<P style="font-family:times;"><FONT SIZE=2><B> Company Overview  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most sensitive data. Our security-as-a-service platform is comprised of
an integrated suite of on-demand data protection solutions, including
threat protection, regulatory compliance, archiving and governance, and secure communication. Our solutions are built on a flexible, cloud-based platform and leverage a number of proprietary
technologies, including big data analytics, machine learning, deep content inspection, secure storage and advanced encryption, to address today's rapidly changing threat landscape. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
fundamental shift in the sources of cyber crime, from hackers to organized crime and governments, combined with the emergence of international data trafficking, are driving an
unprecedented wave of targeted, malicious attacks designed to steal valuable information. At the same time, the growth of business-to-business collaboration, as well as the consumerization of IT and
the associated adoption of mobile devices and unmanaged Internet-based applications, have proliferated sensitive data and reduced the effectiveness of many existing security products. These factors
have contributed to an increasing number of severe data breaches and expanding regulatory mandates, all of which have accelerated demand for effective data protection and governance solutions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
platform addresses this growing challenge by not only protecting data as it flows into and out of the enterprise via on-premise and cloud-based email, instant messaging, social media
and other web-based applications, but also securely archiving these communications for compliance and discovery. We address four important problems for the
enterprise: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In an attempt to defend against the constantly evolving threat landscape and to comply with government mandates, enterprises are
beginning to implement new, more robust corporate policies for data protection, archiving and governance. To enforce these new policies, secure communication technologies and policy-based encryption
are being used to limit the leakage of sensitive data and intellectual property, and archiving and eDiscovery solutions are being used to reduce legal compliance risks. According to International Data
Corporation (IDC), a third-party market research company, the total worldwide market for data protection solutions is estimated to grow from $5.2&nbsp;billion in 2011 to $8.0&nbsp;billion by 2015,
a compound annual growth rate (CAGR) of 11%.* </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Adjusted subscription gross profit  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have included adjusted subscription gross profit, a non-GAAP financial measure, in this prospectus because it is a key measure used
by our management and board of directors to understand and evaluate our operating results, core operating performance, and trends to prepare and approve our annual budget and to develop short- and
long-term operational plans. We have provided a reconciliation between subscription gross profit, the most directly comparable GAAP financial measure, and adjusted subscription gross
profit. We believe that adjusted
subscription gross profit provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
use of adjusted subscription gross profit has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as
reported under GAAP. Because of these limitations, you should consider adjusted subscription gross profit alongside other financial performance measures, including subscription gross profit and our
other GAAP results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have included billings, a non-GAAP financial measure, in this prospectus because it is a key measure used by our management and
board of directors to manage our business and monitor our near term cash flows. We have provided a reconciliation between total revenue, the most directly comparable GAAP financial measure, and
billings. Accordingly, we believe that billings provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board
of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
use of billings as a non-GAAP measure has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for revenue or an analysis of

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have included adjusted EBITDA, a non-GAAP financial measure, in this prospectus because it is a key metric used by our management
and board of directors to measure operating performance and trends and to prepare and approve our annual budget. We define adjusted EBITDA as net loss, adjusted to exclude: depreciation, amortization
of intangibles, interest income (expense), net, provision for income taxes, stock-based compensation, acquisition-related expense, other income, and other expense. We believe that the use of adjusted
EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance
across companies and across periods. We believe that: </FONT></P>

stock-based compensation and non-core operational charges, such as acquisition-related expenses, from adjusted EBITDA because the amount of such expenses in any specific period may not be
directly correlated to the underlying performance of our business operations and these expenses can vary significantly between periods as a result of new acquisitions, full amortization of previously
acquired tangible and intangible assets or the timing of new stock-based awards, as the case may be. </FONT></DD></DL>

use adjusted EBITDA in conjunction with traditional GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the
preparation of
our annual operating budget, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance. </FONT></P>

do not place undue reliance on adjusted EBITDA as our only measures of operating performance. Adjusted EBITDA should not be considered as a substitute for other measures of financial
performance reported in accordance with GAAP. There are limitations to using non-GAAP financial measures, including that other companies may calculate these measures differently than we
do, that they do not reflect our capital expenditures or future requirements for capital expenditures and that they do not reflect changes in, or cash requirements for, our working capital. </FONT></P>

<BR></FONT><FONT SIZE=2><B>  RISK FACTORS    <BR>    </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</FONT><FONT SIZE=2><I>Investing in our common stock involves a high degree of risk. You should carefully consider the following risk
factors, as well as the other information in this prospectus, before deciding whether to invest in shares of our common stock. The occurrence of any of the events described below could harm our
business, financial condition, results of operation and growth prospects. In such an event, the trading price of our common stock may decline and you may lose all or part of your investment.  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Risks Related to Our Business and Industry  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> We have a history of losses, and we are unable to predict the extent of any future losses or when, if ever, we will achieve profitability in the future.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have incurred net losses in every year since our inception, including net losses of $19.7&nbsp;million and $20.9&nbsp;million in
2009 and 2010, respectively. We also had a net loss of $13.7&nbsp;million in the nine months ended September&nbsp;30, 2011. As a result, we had an accumulated deficit of $155.7&nbsp;million as
of September&nbsp;30, 2011. Achieving profitability will require us to increase revenue, manage our cost structure, and avoid unanticipated liabilities. We do not expect to be profitable in the near
term. Revenue growth may slow or revenue may decline for a number of possible reasons, including slowing demand for our solutions, increasing competition, a decrease in the growth of our overall
market, or if we fail for any reason to continue to capitalize on growth opportunities. Any failure by us to obtain and sustain profitability, or to continue our revenue growth, could cause the price
of our common stock to decline significantly. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> We operate in a highly competitive environment with large, established competitors, and our competitors may gain market share in the markets for our solutions that could
adversely affect our business and cause our revenue to decline.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our traditional competitors include security-focused software vendors, such as Symantec Corporation and McAfee,&nbsp;Inc., an Intel
Corporation subsidiary, which offer software products that directly compete with our solutions. In addition to competing with these vendors directly for sales to customers, we compete with them for
the opportunity to have our solutions bundled with the product offerings of our strategic partners. Our competitors could gain market share from us if any of these partners replace our solutions with
the products of our competitors or if these partners more actively promote our competitors' products over our solutions. In addition, software vendors who have bundled our solutions with theirs may
choose to bundle their software with their own or other vendors' software, or may limit our access to standard product interfaces and inhibit our ability to develop solutions for their platform. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
also face competition from large technology companies, such as Cisco Systems,&nbsp;Inc., EMC Corporation, Google&nbsp;Inc., Hewlett-Packard Company, Intel and Microsoft. These
companies are increasingly developing and incorporating into their products data protection and storage software that compete on various levels with our solutions. Our competitive position could be
adversely affected to the extent that our customers perceive that the functionality incorporated into these products would replace the need for our solutions or that buying from one vendor would
provide them with increased leverage and purchasing power and a better customer experience. We also face competition from many smaller companies that specialize in particular segments of the markets
in which we compete. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Many
of our competitors have greater financial, technical, sales, marketing or other resources than we do and consequently may have the ability to influence our customers to purchase
their products instead of ours. Further consolidation within our industry or other changes in the competitive environment could also result in larger competitors that compete with us on several
levels. In addition, acquisitions of smaller companies that specialize in particular segments of the markets in which we compete by large technology companies would result in increased competition
from these large </FONT></P>

companies. For example, Google's acquisition of Postini, an email and web security and archiving service, resulted in Google becoming one of our competitors. If we are unsuccessful in
responding to our competitors or to changing technological and customer demands, our competitive position and financial results could be adversely affected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If we are unable to maintain high subscription renewal rates, our future revenue and operating results will be harmed.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our customers have no obligation to renew their subscriptions for our solutions after the expiration of their initial subscription
period, which typically ranges from one to three years. In addition, our customers may renew for fewer subscription services or users, renew for shorter contract lengths or renew at lower prices due
to competitive or other pressures. We cannot accurately predict renewal rates and our renewal rates may decline or fluctuate as a result of a number of factors, including competition, customers' IT
budgeting and spending priorities, and deteriorating general economic conditions. If our customers do not renew their subscriptions for our solutions, our revenue would decline and our business would
suffer. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If we are unable to sell additional solutions to our customers, our future revenue and operating results will be harmed.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our future success depends on our ability to sell additional solutions to our customers. This may require increasingly sophisticated
and costly sales efforts and may not result in additional sales. In addition, the rate at which our customers purchase additional solutions depends on a number of factors, including the perceived need
for additional solutions, growth in the number of end-users, and general economic conditions. If our efforts to sell additional solutions to our customers are not successful, our business
may suffer. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If our solutions fail to protect our customers from security breaches, our brand and reputation could be harmed, which could have a material adverse effect on our business
and results of operations.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The threats facing our customers are constantly evolving and the techniques used by attackers to access or sabotage data change
frequently. As a result, we must constantly update our solutions to respond to these threats. If we fail to update our solutions in a timely or effective manner to respond to these threats, our
customers could experience security breaches. Many state and foreign governments have enacted laws requiring companies to notify individuals of data security breaches involving their personal data.
These mandatory disclosures regarding a security breach often lead to widespread negative publicity, and any association of us with such publicity may cause our customers to lose confidence in the
effectiveness of our data security measures. Any security breach at one of our customers would harm our reputation as a secure and trusted company and could cause the loss of customers. Similarly, if
a well-publicized breach of data security at a customer of any other cloud-based data protection or archiving service provider or other major enterprise cloud services provider were to
occur, there could be a loss of confidence in the cloud-based storage of sensitive data and information generally. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, our solutions work in conjunction with a variety of other elements in customers' IT and security infrastructure, and we may receive blame and negative publicity for a
security breach that may have been the result of the failure of one of the other elements not provided by us. The occurrence of a breach, whether or not caused by our solutions, could delay or reduce
market acceptance of our solutions and have an adverse effect on our business and financial performance. In addition, any revisions to our solutions that we believe may be necessary or appropriate in
connection with any such breach may cause us to incur significant expenses. Any of these events could have material adverse effects on our brand and reputation, which could harm our business,
financial condition, and operating results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If our customers experience data losses, our brand, reputation and business could be harmed.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our customers rely on our archive solutions to store their corporate data, which may include financial records, credit card
information, business information, health information, other personally identifiable information or other sensitive personal information. A breach of our network security and systems or other events
that cause the loss or public disclosure of, or access by third parties to, our customers' stored files or data could have serious negative consequences for our business, including possible fines,
penalties and damages, reduced demand for our solutions, an unwillingness of our customers to use our solutions, harm to our brand and reputation, and time-consuming and expensive
litigation. The techniques used to obtain unauthorized
access, disable or degrade service, or sabotage systems change frequently, often are not recognized until launched against a target, and may originate from less regulated or remote areas around the
world. As a result, we may be unable to proactively prevent these techniques, implement adequate preventative or reactionary measures, or enforce the laws and regulations that govern such activities.
In addition, because of the large amount of data that we collect and manage, it is possible that hardware failures, human errors or errors in our systems could result in data loss or corruption, or
cause the information that we collect to be incomplete or contain inaccuracies that our customers regard as significant. If our customers experience any data loss, or any data corruption or
inaccuracies, whether caused by security breaches or otherwise, our brand, reputation and business would be harmed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
errors and omissions insurance may be inadequate or may not be available in the future on acceptable terms, or at all. In addition, our policy may not cover any claim against us for
loss of data or other indirect or consequential damages. Defending a suit based on any data loss or system disruption, regardless of its merit, could be costly and divert management's attention. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Defects or vulnerabilities in our solutions could harm our reputation, reduce the sales of our solutions and expose us to liability for losses.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Because our solutions are complex, undetected errors, failures or bugs may occur, especially when solutions are first introduced or
when new versions or updates are released despite our efforts to test those solutions and enhancements prior to release. We may not be able to correct defects, errors, vulnerabilities or failures
promptly, or at all. </FONT></P>

of liability provisions in our standard terms and conditions may not adequately or effectively protect us from any claims related to defects, errors, vulnerabilities or
failures in our solutions, including as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><B><I> Because we provide security solutions, our software, website and internal systems may be subject to intentional disruption that could adversely impact our reputation and
future sales.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We could be a target of attacks specifically designed to impede the performance of our solutions and harm our reputation. Similarly,
experienced computer hackers may attempt to penetrate our network security or the security of our website and misappropriate proprietary information and/or cause interruptions of our services. Because
the techniques used by such computer hackers to access or sabotage networks change frequently and may not be recognized until launched against a target, we may be unable to anticipate these
techniques. If an actual or perceived breach of network security occurs, it could adversely affect the market perception of our solutions, and may expose us to the loss of information, litigation and
possible liability. In addition, such a security breach could impair our ability to operate our business, including our ability to provide support services to our customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> We believe that there is a trend for large and mid-sized enterprises to migrate their on-premise email systems to cloud-based offerings. If we fail to successfully develop,
market, broaden or enhance our solutions to continue to be attractive to existing customers currently using cloud-based email systems or by new prospects, our ability to grow or maintain our revenue
could be harmed, and our business could suffer.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We derive a substantial portion of our revenue from our solutions that protect and archive data in our customers'
on-premise email systems and expect to continue to do so for the foreseeable future. We currently derive a portion of our revenue from customers using cloud-based email systems
such as Google's Google Apps and Microsoft's Office 365, both of which include varying degrees of threat protection and governance services as part of their offering. A significant market shift from
on-premise email systems toward such cloud-based email systems could decrease demand for our solutions because customers who move to cloud-based email systems may no longer value our solutions; if our
current or prospective customers who utilize cloud-based email systems fail to find value in our solutions, our business could be adversely affected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Historically, our solutions have been used primarily for email, and any decrease in the use of email systems by large and mid-sized enterprises over time, or the failure of
our newly developed solutions for emerging methods of communication and collaboration to gain acceptance could harm our business.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically, our customers have primarily used our solutions to protect and archive data in their corporate email systems. If the use
of email decreases, demand for our solutions would decrease and we may fail to diversify our revenue base by increasing demand for our other technology solutions. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, messaging and collaboration technologies are evolving rapidly. For instance, the widespread adoption and use of mobile devices, unmanaged Internet-based collaboration and
file sharing applications and social networking sites have caused valuable and sensitive data to proliferate well beyond traditional corporate email systems, resulting in new and increasing security
risks. We are devoting resources to continue developing and marketing our solutions for these emerging methods of communication and collaboration. However, our customers may not perceive the need to
deploy our solutions intended to address these emerging areas. If we are unable to successfully develop, market, broaden or enhance our solutions to address the wider range of threats caused by the
proliferation of new technologies and methods of communication, demand for our existing solutions would decrease, and our business would be harmed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If functionality similar to that offered by our solutions is incorporated into our competitors' networking products, potential or existing customers may decide against
adding our solutions to their network, which would have an adverse effect on our business.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Some large, well-established providers of networking equipment, such as Cisco and Juniper Networks,&nbsp;Inc. currently
offer, and may continue to introduce, network security features that compete with our solutions, either in stand-alone security products or as additional features in their network infrastructure
products. The inclusion of, or the announcement of an intent to include, functionality perceived to be similar to that offered by our solutions in networking products that are already generally
accepted as necessary components of customers' network architecture may have an adverse effect on our ability to market and sell our solutions. Furthermore, even if the functionality offered by
network infrastructure providers is more limited than that offered by our solutions, a significant number of our customers may elect to accept such limited functionality in lieu of adding appliances
or software from an additional vendor such as us. Many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep
relationships with other providers of networking products, which may make them reluctant to add new third-party components to their networks. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Our solutions collect, filter and archive customer data which may contain personal information, which raises privacy concerns and could result in us having liability or
inhibit sales of our solutions.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Many federal, state and foreign government bodies and agencies have adopted or are considering adopting laws and regulations regarding
the collection, use, and disclosure of personal information. Because many of the features of our solutions use, store, and report on customer data which may contain personal information from our
customers, any inability to adequately
address privacy concerns, or comply with applicable privacy laws, regulations and policies could, even if unfounded, result in liability to us, damage to our reputation, loss of sales, and harm to our
business. Furthermore, the costs of compliance with, and other burdens imposed by, such laws, regulations and policies that are applicable to the businesses of our customers may limit the use and
adoption of our solutions and reduce overall demand for them. Privacy concerns, whether or not valid, may inhibit market adoption of our solutions. For example, in the United States regulations such
as the Gramm-Leach-Bliley Act (GLBA), which protects and restricts the use of consumer credit and financial information, and the Health Insurance Portability and Accountability Act of 1996 (HIPAA),
which regulates the use and disclosure of personal health information, impose significant security and data protection requirements and obligations on businesses that may affect the use and adoption
of our solutions. The European Union has also adopted a data privacy directive that requires member states to impose restrictions on the collection and use of personal data that, in some respects, are
more stringent, and impose more significant burdens on subject businesses, than current privacy standards in the United States. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
failure or perceived failure to comply with laws and regulations may result in proceedings or actions against us by government entities or others, or could cause us to lose users and
customers, which could potentially have an adverse effect on our business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If we do not effectively expand and train our sales force, we may be unable to add new customers or increase sales to our existing customers and our business will be harmed.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We continue to be substantially dependent on our sales force to obtain new customers and to sell additional solutions to our existing
customers. We believe that there is significant competition for sales personnel with the skills and technical knowledge that we require. Our ability to achieve significant revenue growth will depend,
in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel to support our growth. New hires require significant training and may take significant time
before they achieve full productivity. Our recent hires and planned hires may not become as productive as we expect, and we may be unable to hire or retain sufficient numbers of </FONT></P>

successful in obtaining new customers or increasing sales to our existing customer base, our business will be harmed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Our sales cycle is long and unpredictable, and our sales efforts require considerable time and expense. As a result, our results are difficult to predict and may vary
substantially from quarter to quarter, which may cause our operating results to fluctuate.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We sell our security and compliance offerings primarily to enterprise IT departments that are managing a growing set of user and
compliance demands, which has increased the complexity of customer requirements to be met and confirmed in the sales cycle. Additionally, we have found that increasingly security, legal and compliance
departments are involved in testing, evaluating and finally approving purchases, which has also made the sales cycle longer and less predictable. We may not be able to accurately predict or forecast
the timing of sales, which makes our future revenue difficult to predict and could cause our results to vary significantly. In addition, we might devote substantial time and effort to a particular
unsuccessful sales effort, and as a result we could lose other sales opportunities or incur expenses that are not offset by an increase in revenue, which could harm our business. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><B><I> Because our long-term success depends, in part, on our ability to expand the sales of our platform to our customers located outside of the United States, our

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;One key element of our growth strategy is to develop a worldwide customer base and expand our operations worldwide. We have added
employees, offices and customers internationally, particularly in Europe and Asia. Operating in international markets requires significant resources and management attention and will subject us to
regulatory, economic, political and competitive risks and competition that are different from those in the United States. Because of our limited experience with international operations, we cannot
assure you that our international expansion efforts will be successful or that expected returns on such investments will be achieved in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our success will depend to a substantial extent on the willingness of enterprises, large and small, to increase their use of cloud
computing services. The market for messaging security and data compliance solutions delivered as a service in particular is at an early stage relative to on-premise solutions, and these
applications may not achieve and sustain high levels of demand and market acceptance. Many enterprises have invested substantial personnel and financial resources to integrate traditional enterprise
software or hardware appliances for these applications into their businesses or may be reluctant or unwilling to use cloud computing services because they have concerns regarding the risks associated
with reliability and security, among other things, of this delivery model, or its ability to help them comply with applicable laws and regulations. If enterprises do not perceive the benefits of this
delivery model, then the market for our services may develop more slowly than we expect, which would adversely affect our business and operating results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our ability to attract new customers and increase revenue from existing customers will depend in large part on our ability to enhance
and improve our existing solutions and to introduce new solutions. The success of any enhancement or new solution depends on several factors, including the timely completion, introduction and market
acceptance of the enhancement or solution. Any new enhancement or solution we develop or acquire may not be introduced in a timely or cost-effective manner and may not achieve the broad
market acceptance necessary to generate significant revenue. If we are unable to successfully develop or acquire new solutions or enhance our existing solutions to meet customer requirements, we may
not grow as expected and we may not achieve profitability. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
cannot be certain that our development activities will be successful or that we will not incur delays or cost overruns. Furthermore, we may not have sufficient financial resources to
identify and develop new technologies and bring enhancements or new solutions to market in a timely and cost effective manner. New technologies and enhancements could be delayed or cost more than we
expect, and we cannot ensure that any of these solutions will be commercially successful if and when they are introduced. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have derived and anticipate that in the future we will continue to derive a substantial portion of the sales of our solutions
through channel partners. In order to scale our channel program to support growth in our business, it is important that we continue to help our partners enhance their ability to independently sell and
deploy our solutions. We may be unable to continue to successfully expand and improve the effectiveness of our channel sales program. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
agreements with our channel partners are generally non-exclusive and some of our channel partners have entered, and may continue to enter, into strategic relationships
with our competitors or are competitors themselves. Further, many of our channel partners have multiple strategic relationships and they may not regard us as significant for their businesses. Our
channel partners may terminate their respective relationships with us with limited or no notice and with limited or no penalty, pursue other partnerships or relationships, or attempt to develop or
acquire products or services that compete with our solutions. Our partners also may impair our ability to enter into other desirable strategic relationships. If our channel partners do not effectively
market and sell our
solutions, if they choose to place greater emphasis on products of their own or those offered by our competitors, or if they fail to meet the needs of our customers, our ability to grow our business
and sell our solutions may be adversely affected. Similarly, the loss of a substantial number of our channel partners, and our possible inability to replace them, the failure to recruit additional
channel partners, any reduction or delay in their sales of our solutions, or any conflicts between channel sales and our direct sales and marketing activities could materially and adversely affect our
results of operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Because we recognize revenue from subscriptions over the term of the relevant service period, decreases or increases in sales are not immediately reflected in full in our

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We recognize revenue from subscriptions over the term of the relevant service period, which typically range from one to three years,
with some up to five years. As a result, most of our quarterly revenue from subscriptions results from agreements entered into during previous quarters. Consequently, a shortfall in demand for our
solutions in any quarter may not significantly reduce our subscription revenue for that quarter, but could negatively affect subscription revenue in future quarters. We may be unable to adjust our
cost structure to compensate for this potential shortfall in subscription revenue. Accordingly, the effect of significant downturns in sales of subscriptions may not be fully reflected in our results
of operations until future periods. Our subscription model also makes it difficult for us to rapidly increase our subscription revenue through additional sales in any period, as subscription revenue
must be recognized over the term of the contract. </FONT></P>

business also depends on our customers having high-speed access to the Internet. Any Internet outages or delays could adversely affect our ability to provide our solutions to our
customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
operations also rely heavily on the availability of electricity, which also comes from third-party providers. If we or the third-party data center facilities that we use to deliver
our services were to experience a major power outage or if the cost of electricity were to increase significantly, our operations and financial results could be harmed. If we or our third-party data
centers were to experience a major power outage, we or they would have to rely on back-up generators, which might not work properly or might not provide an adequate supply during a major
power outage. Such a power outage could result in a significant disruption of our business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
occurrence of an extended interruption of ours or third-party services for any reason could result in lengthy interruptions in our services or in the delivery of customers' email and
require us to provide service credits, refunds, indemnification payments or other payments to our customers, and could also result in the loss of customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Any failure to offer high-quality technical support services may adversely affect our relationships with our customers and harm our financial results.  </I></B></FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Once our solutions are deployed, our customers depend on our support organization to resolve any technical issues relating to our
solutions. In addition, our sales process is highly dependent on our solutions and business reputation and on strong recommendations from our existing customers. Any failure to maintain
high-quality technical support, or a market perception that we do not maintain high-quality support, could harm our reputation, adversely affect our ability to sell our
solutions to existing and prospective customers, and harm our business, operating results and financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
offer technical support services with many of our solutions. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support
services. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. Increased customer demand for these services, without
corresponding revenue, could increase costs and adversely affect our operating results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have outsourced a substantial portion of our worldwide customer support functions to third-party service providers. If these companies experience financial difficulties, do not
maintain sufficiently skilled workers and resources to satisfy our contracts, or otherwise fail to perform at a sufficient level, the level of support services to our customers may be significantly
disrupted, which could materially harm our reputation and our relationships with these customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe that developing and maintaining awareness and integrity of our company and our brand are important to achieving widespread
acceptance of our existing and future offerings and are important elements in attracting new customers. We believe that the importance of brand recognition will increase as competition in our market
further intensifies. Successful promotion of our brand will depend on the effectiveness of our marketing efforts and on our ability to provide reliable and useful solutions at competitive prices. We
plan to continue investing substantial resources to promote our brand, both domestically and internationally, but there is no guarantee that our brand development strategies will enhance the
recognition of our brand. Some of our existing and potential competitors have well-established brands with greater recognition than we have. If our efforts to promote and maintain our
brand are not successful, our operating results and our ability to attract and retain customers may be adversely affected. In addition, even if our brand recognition and loyalty increases, this may
not result in increased use of our solutions or higher revenue. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, independent industry analysts often provide reviews of our solutions, as well as those of our competitors, and perception of our solutions in the marketplace may be
significantly influenced by these reviews. We have no control over what these industry analysts report, and because industry
analysts may influence current and potential customers, our brand could be harmed if they do not provide a positive review of our solutions or view us as a market leader. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> The steps we have taken to protect our intellectual property rights may not be adequate.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We rely on a combination of contractual rights, trademarks, trade secrets, patents and copyrights to establish and protect our
intellectual property rights. These offer only limited protection, however, and the steps we have taken to protect our proprietary technology may not deter its misuse, theft or misappropriation. Any
of our patents, copyrights, trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Competitors may independently
develop technologies or products that are substantially equivalent or superior to our solutions or that inappropriately incorporate our proprietary technology into their products. Competitors may hire
our former employees who may misappropriate our proprietary technology or misuse our confidential information. Although we rely in part upon confidentiality agreements with our employees, consultants
and other third parties to protect our trade secrets and other confidential information, those agreements may not effectively prevent disclosure of trade secrets and other confidential information and
may not provide an adequate remedy in the event of misappropriation of trade secrets or unauthorized disclosure of confidential information. In addition, others may independently discover our trade
secrets and confidential information, and in such cases we could not assert any trade secret rights against such parties. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
might be required to spend significant resources to monitor and protect our intellectual property rights. We may initiate claims or litigation against third parties for infringement
of our intellectual property rights or misappropriation of our trade secrets, or to establish the validity of our intellectual property rights. Any litigation, whether or not it is resolved in our
favor, could result in significant expense to us and divert the efforts of our technical and management personnel, which may adversely affect our business, operating results and financial condition.
Certain jurisdictions may not provide adequate legal infrastructure for effective protection of our intellectual property rights. Changing legal interpretations of liability for unauthorized use of
our solutions or lessened sensitivity by corporate, government or institutional users to refraining from intellectual property piracy or other infringements of intellectual property could also harm
our business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
issued patents may not provide us with any competitive advantages or may be challenged by third parties, and our patent applications may never be granted at all. It is possible that
innovations for which we seek patent protection may not be protectable. Additionally, the process of obtaining patent </FONT></P>

is expensive and time consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. Given the cost, effort, risks
and downside of obtaining patent protection, including the requirement to ultimately disclose the
invention to the public, we may not choose to seek patent protection for certain innovations. However, such patent protection could later prove to be important to our business. Even if issued, there
can be no assurance that any patents will have the coverage originally sought or adequately protect our intellectual property, as the legal standards relating to the validity, enforceability and scope
of protection of patent and other intellectual property rights are uncertain. Any patents that are issued may be invalidated or otherwise limited, or may lapse or may be abandoned, enabling other
companies to better develop products that compete with our solutions, which could adversely affect our competitive business position, business prospects and financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
cannot assure you that the measures we have taken to protect our intellectual property will adequately protect us, and any failure to protect our intellectual property could harm our
business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Third parties claiming that we infringe their intellectual property rights could cause us to incur significant legal expenses and prevent us from selling our solutions.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Companies in the software and technology industries, including some of our current and potential competitors, own large numbers of
patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement, misappropriation or other violations of intellectual property rights. In
addition, many of these companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them.
The litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our potential patents may provide little or no deterrence. We
have received, and may in the future receive, notices that claim we have infringed, misappropriated or otherwise violated other parties' intellectual property rights. To the extent we gain greater
visibility, we face a higher risk of being the subject of intellectual property infringement claims, which is not uncommon with respect to software technologies in general and information security
technology in particular. There may be third-party intellectual property rights, including issued or pending patents that cover significant aspects of our technologies or business methods. Any
intellectual property claims, with or without merit, could be very time consuming, could be expensive to settle or litigate and could divert our management's attention and other resources. These
claims could also subject us to significant liability for damages, potentially including treble damages if we are found to have willfully infringed patents or copyrights. These claims could also
result in our having to stop using technology found to be in violation of a third party's rights. We might be required to seek a license for the intellectual property, which may not be available on
reasonable terms or at all. Even if a license were available, we could be required to pay significant royalties, which would increase our operating expenses. As a result, we may be required to develop
alternative non-infringing technology, which could require significant effort and expense. If we cannot license or develop technology for any infringing aspect of our business, we would be
forced to limit or stop sales of one or more of our solutions or features of our solutions and may be unable to compete effectively. Any of these results would harm our business, operating results and
financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, our agreements with customers and channel partners include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of
claims of
intellectual property infringement and, in some cases, for damages caused by us to property or persons. Large indemnity payments could harm our business, operating results and financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We utilize various types of software and other technology, as well as intellectual property rights, licensed from unaffiliated third
parties in order to provide certain elements of our solutions. Any errors or defects in any third-party technology could result in errors in our solutions that could harm our business. In addition,
licensed technology and intellectual property rights may not continue to be available on commercially reasonable terms, or at all. While we believe that there are currently adequate replacements for
the third-party technology we use, any loss of the right to use any of this technology on commercially reasonable terms, or at all, could result in delays in producing or delivering our solutions
until equivalent technology is identified and integrated, which delays could harm our business. In this situation we would be required to either redesign our solutions to function with software
available from other parties or to develop these components ourselves, which would result in increased costs. Furthermore, we might be forced to limit the features available in our current or future
solutions. If we fail to maintain or renegotiate any of these technology or intellectual property licenses, we could face significant delays and diversion of resources in attempting to develop similar
or replacement technology, or to license and integrate a functional equivalent of the technology. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Some of our solutions contain "open source" software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our
business.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Some of our solutions are distributed with software licensed by its authors or other third parties under so-called "open
source" licenses, which may include, by way of example, the GNU General Public License, or&nbsp;GPL, and the Apache License. Some of these licenses contain requirements that we make available source
code for modifications or derivative works we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license
or other license granting third parties certain rights of further use. By the terms of certain open source licenses, we could be required to release the source code of our proprietary software, and to
make our proprietary software available under open source licenses, if we combine our proprietary software with open source software in a certain manner. In the event that portions of our proprietary
software are determined to be subject to an open source license, we could be required to publicly release the affected portions of our source code, re-engineer all or a portion of our
technologies, or otherwise be limited in the licensing of our technologies, each of which could reduce or eliminate the value of our technologies and
solutions. In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third party commercial software, as open source licensors generally
do not provide warranties or controls on the origin of the software. We have established processes to help alleviate these risks, including a review process for screening requests from our development
organizations for the use of open source software, but we cannot be sure that all open source software is submitted for approval prior to use in our solutions, that our programmers have not
incorporated open source software into our proprietary solutions and technologies or that they will not do so in the future. In addition, many of the risks associated with usage of open source
software cannot be eliminated, and could, if not properly addressed, negatively affect our business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Governmental regulations affecting the export of certain of our solutions could negatively affect our business.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our products are subject to U.S. export controls, and we incorporate encryption technology into certain of our products. These
encryption products and the underlying technology may be exported outside the United States only with the required export authorizations, including by license, a license exception or other appropriate
government authorizations, including the filing of an encryption registration. Governmental regulation of encryption technology and regulation of imports or exports, or our failure to obtain required
import or export approval for our products, could harm our international sales and adversely affect our revenue. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
determined that subsequent to August 2008, we may have shipped a particular hardware appliance model to a limited number of international customers that, prior to shipment, may have
required either a one-time product review or application for an encryption registration number in lieu of such product review. We are making a voluntary submission to the U.S. Commerce
Department's Bureau of Industry and Security (BIS) to report this potential violation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, the U.S. government also prohibits U.S. companies from doing business with customers in certain restricted countries. As part of a pre-IPO due diligence review,
we discovered a potential export violation involving the provision of web-based, email communication services to end-users located in Iran through our Everyone.net service,
which we acquired in October 2009. Neither of these suspected end-users appears to have been a current customer of these web-based, email communication services since late 2010
or early 2011. Although we had ceased providing the services, we are making a voluntary submission to the U.S. Department of Treasury's Office of Foreign Assets Control (OFAC) to report this potential
violation. Our investigation of these matters is still ongoing, and it is possible that we may discover additional violations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Failure

will depend, in part, on our ability to manage these changes effectively. We will need to continue to improve our operational, financial and management controls and our reporting systems and
procedures. Failure to effectively manage growth could result in declines in service quality or customer satisfaction, increases in costs, difficulties in introducing new features or other operational
difficulties. Any failure to effectively manage growth could adversely impact our business and reputation. </FONT></P>

technologies, products, personnel or operations of acquired companies, particularly if the key personnel of the acquired business choose not to work for us, and we may have difficulty retaining the
customers of any acquired business. Acquisitions may also disrupt our ongoing business, divert our resources and require significant management attention that would otherwise be available for
development of our business. Any acquisition or investment could expose us to unknown liabilities. In addition, as of September&nbsp;30, 2011, we had $20.4&nbsp;million in goodwill and intangible
assets recorded on our consolidated balance sheet. We may in the future need to incur charges with respect to the write-down or impairment of goodwill or intangible assets, which could
adversely affect our operating results. Moreover, we cannot assure you that the anticipated benefits of any acquisition or investment would be realized or that we would not be exposed to unknown
liabilities. In connection with these types of transactions, we may issue additional equity securities that would dilute our stockholders, use cash that we may need in the future to operate our
business, incur debt on terms unfavorable to us or that we are unable to repay, incur large charges or substantial liabilities, encounter difficulties integrating diverse business cultures, and become

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our future success depends upon our ability to recruit and retain key management, technical, sales, marketing, finance, and other
critical personnel. Despite the economic
downturn, competition for qualified management, technical and other personnel is intense, and we may not be successful in attracting and retaining such personnel. If we fail to attract and retain
qualified employees, our ability to grow our business could be harmed. Our officers and other key personnel are employees-at-will, and we cannot assure you that we will be able
to retain them. Competition for people with the specific skills that we require is significant. In order to attract and retain personnel in a competitive marketplace, we believe that we must provide a
competitive compensation package, including cash and equity-based compensation. Volatility in our stock price may from time to time adversely affect our ability to recruit or retain employees. If we
are unable to hire and retain qualified employees, or conversely, if we fail to manage employee performance or reduce staffing levels when required by market conditions, our business and operating
results could be adversely affected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

recorded sales tax liabilities of $0.1&nbsp;million on our consolidated balance sheet as of September&nbsp;30, 2011 in respect of sales and use tax liabilities in various states and local
jurisdictions. It is possible that we could face sales tax audits and that our liability for these taxes could exceed our estimates as state tax authorities could still assert that we are obligated to
collect additional amounts as taxes from our customers and remit those taxes to those authorities. We could also be subject to audits with respect to state and international jurisdictions for which we
have not accrued tax liabilities. A successful assertion that we should be collecting additional sales or other taxes on our services in jurisdictions where we have not historically done so and do not
accrue for sales taxes could result in substantial tax liabilities for past sales, discourage customers from purchasing our application or otherwise harm our business and operating results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our financial performance depends, in part, on the state of the economy, which deteriorated in the recent broad recession, and which
may deteriorate in the future. Challenging economic conditions worldwide have from time to time contributed, and may continue to contribute, to slowdowns in the information technology industry,
resulting in reduced demand for our solutions as a result of continued constraints on IT-related capital spending by our customers and increased price competition for our solutions.
Moreover, we target some of our solutions to the financial services industry and therefore if there is consolidation in that industry, or layoffs, or lack of funding for IT purchases, our business may
suffer. If unfavorable economic conditions continue or worsen, our business, financial condition and operating results could be materially and adversely affected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Natural disasters or other catastrophic events may cause damage or disruption to our operations, international commerce and the global

or other natural disaster, fire, act of terrorism or other catastrophic event that results in the destruction or disruption of any of our critical business operations or information technology systems
could severely affect our ability to conduct normal business operations and, as a result, our future operating results could be harmed. These negative events could make it difficult or impossible for
us to deliver our services to our customers, and could decrease demand for our services. Because we do not carry earthquake insurance for direct quake-related losses, </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales to U.S. and foreign federal, state and local governmental agency customers have accounted for a portion of our revenue in past
periods, and we may in the future increase sales to government entities. Sales into government entities are subject to a number of risks. Selling to government entities can be highly competitive,
expensive and time consuming, often requiring significant upfront time and expense without any assurance that we will win a sale. We have invested in the creation of a cloud offering certified under
the Federal Information Security Management Act (FISMA) for government usage but we cannot be sure that we will continue to sustain or renew this certification, that the government will continue to
mandate such certification or that other government agencies or entities will use this cloud offering. Government demand and payment for our solutions may be impacted by public sector budgetary cycles
and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our solutions. Government entities may have contractual or other legal rights to terminate
contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our future results of operations. For example, if the distributor
receives a significant portion of its revenue from sales to such governmental entity, the financial health of the distributor could be substantially harmed, which could negatively affect our future
sales to such distributor. Governments routinely investigate and audit government contractors' administrative processes, and any unfavorable audit could result in the government refusing to continue
buying our solutions, a reduction of revenue or fines or civil or criminal liability if the audit uncovers improper or illegal activities. Any such penalties could adversely impact our results of
operations in a material way. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> If we fail to maintain an effective system of internal controls, our ability to produce timely and accurate financial statements or comply with applicable regulations could
be impaired.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, and the rules and regulations of the NASDAQ Global Market. We expect that the requirements of these rules and regulations will continue to increase our legal, accounting and
financial compliance costs, make some activities more difficult, time consuming and costly, and place significant strain on our personnel, systems and resources. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to
develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the Securities and Exchange
Commission, or the SEC, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in reports under the
Exchange Act is accumulated and communicated to our principal executive and financial officers. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further, weaknesses in our internal controls may be
discovered in the future. Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm our operating results or cause us to
fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal controls also could
adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over
financial reporting that we are required </FONT></P>

reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will
continue to expend, significant resources, including accounting-related costs, and provide significant management oversight. Any failure to maintain the adequacy of our internal controls, or
consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. In the event that
we are not able to demonstrate compliance with Section&nbsp;404 of the Sarbanes-Oxley Act that our internal controls are perceived as
inadequate or that we are unable to produce timely or accurate financial statements, investors may lose confidence in our operating results and our stock price could decline. In addition, if we are
unable to continue to meet these requirements, we may not be able to remain listed on The NASDAQ Global Market. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
are not currently required to comply with the SEC rules that implement Sections&nbsp;302 and 404 of the Sarbanes-Oxley Act, and are therefore not required to make a formal
assessment of the effectiveness of our internal controls over financial reporting for that purpose. Upon becoming a public company, we will be required to comply with these rules, which will require
management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal control over financial reporting.
Though we will be required to disclose changes made in our internal control and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal control
over financial reporting pursuant to Section&nbsp;404 until the year following our first annual report required to be filed with the SEC. To comply with the requirements of being a public company,
we may need to undertake various actions, such as implementing new internal controls and procedures and hiring accounting or internal audit staff. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until the year following our
first annual report required to be filed with the SEC. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the
level at which our controls are documented, designed or operating. Our remediation efforts may not enable us to avoid a material weakness in the future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> We will incur significantly increased costs and devote substantial management time as a result of operating as a public company.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. For
example, we will be required to comply with the requirements of the Sarbanes-Oxley Act and the Dodd Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently
implemented by the SEC, and the NASDAQ Global Market, our stock exchange, including the establishment and maintenance of effective disclosure and financial controls and changes in corporate governance
practices. We expect that compliance with these requirements will increase our legal and financial compliance costs and will make some activities more time consuming and costly. In addition, we expect
that our management and other personnel will need to divert attention from operational and other business matters to devote substantial time to these public company requirements. In particular, we
expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section&nbsp;404 of the Sarbanes-Oxley Act. In that regard, we
currently do not have an internal audit function, and we will need to hire additional accounting and financial staff with appropriate public company experience and </FONT></P>

operating as a public company will make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The initial public offering price of our common stock will be substantially higher than the net tangible book value per share of our
outstanding common stock immediately after this offering. Therefore, if you purchase our common stock in this offering, you will incur immediate
dilution of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;in net tangible book value per share from the price you paid assuming we offer our shares at
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;, the mid-point of the range on the cover of this
prospectus. In addition, investors purchasing common stock in this offering will have contributed&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of the total consideration paid by our stockholders to purchase shares of common
stock, but will own&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of our outstanding common stock. Moreover, we issued options and a warrant in the past to acquire common stock at prices significantly below the initial public
offering price. As of September&nbsp;30, 2011, there were 20,227,426 shares of our common stock issuable upon the exercise of stock options outstanding, with a weighted-average exercise price of
$1.73 per share. To the extent that these outstanding options are ultimately exercised, you will incur further dilution. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> An active, liquid and orderly trading market for our common stock may not develop, the price of our stock may be volatile, and you could lose all or part of your investment.  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior to this offering, there has been no public market for our common stock. We cannot predict the extent to which investor interest
in us will lead to the development of an active trading market in our common stock or how liquid that market might become. An active public market for our common stock may not develop or be sustained
after the offering. If an active public market does not develop or is not sustained, it may be difficult for you to sell your shares of common stock at a price that is attractive to you, or at all.
The market price for shares of our common stock may decline below the initial public offering price, and you may not be able to resell your shares of common stock at or above the initial public
offering price. In addition, the trading price of our common stock following the offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors,
including but not limited to, those described in this "Risk Factors" section, performance by other companies in our industry and in the technology industry generally, and overall market conditions,
some of which are beyond our control. If the stock market in general experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our
business, financial condition or results of operations. Some companies that have had volatile market prices for their securities have had securities class actions filed against them. If a suit were
filed against us, regardless of its merits or outcome, it would likely result in substantial costs and divert management's attention and resources. This could have a material adverse effect on our
business, operating results and financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms, if at
all. If we raise additional equity financing, our stockholders may experience significant dilution of their ownership interests and the per share value of our common stock could decline. If we issue
equity securities in any additional financing, the
new securities may have rights and preferences senior to our common stock. If we engage in debt financing, we may be required to accept terms that restrict our ability to incur additional indebtedness
and force us to maintain specified liquidity or other ratios. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among other

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This prospectus contains estimates and other statistical data, including those relating to our industry, that we have obtained from
industry publications and reports, including reports from IDC, Ponemon Institute and Gartner, Inc. These industry publications and reports generally indicate that they have obtained their information
from sources believed to be reliable, but do not guarantee the accuracy and completeness of their information. This information involves a number of assumptions and limitations, and you are cautioned
not to give undue weight to these estimates, as there is no assurance that any of them will be reached. Although we have not independently verified the accuracy or completeness of the data contained
in these industry publications and reports, based on our industry experience we believe that the publications and reports are reliable and that the conclusions contained in the publications and
reports are reasonable. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in "Risk Factors." These and other
factors could cause our actual results to differ materially from those expressed in the industry publications and reports. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
reports from Gartner described herein, or the Gartner Reports, represent data, research opinion or viewpoints published as part of a syndicated subscription service, by Gartner, and
are not representations of fact. Each Gartner Report speaks as of its original publication date (and not as of the date of this prospectus) and the opinions expressed in the Gartner Reports are
subject to change without notice. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We estimate that the net proceeds from the sale of shares of our common stock that we are selling in this offering will be
approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, based on an assumed initial public offering price of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share, which is
the midpoint of the estimated offering price range set forth on
the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters' option to purchase
additional shares from us is exercised in full, we estimate that we will receive additional net proceeds of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million. We will not receive any proceeds from the sale of
shares of
our common stock by the selling stockholders. A $1.00 increase or decrease in the assumed initial public offering price of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share would increase or decrease the net proceeds
that
we receive from this offering by approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, assuming the number of shares offered by us remains the same and after deducting the estimated underwriting
discounts
and commissions payable by us. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
expect to use the net proceeds that we receive from this offering for working capital and other general corporate purposes. We may also use a portion of the net proceeds that we
receive from this offering for investments in or acquisitions of complementary businesses, products, services, technologies or other assets. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except
as set forth above, we currently have no specific plans for the use of the net proceeds that we receive from this offering. Accordingly, we will have broad discretion in using the
net proceeds that we receive from this offering. Pending the use of proceeds from this offering as described above, we plan to invest the net proceeds in short-term, interest-bearing
obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have never declared or paid any cash dividends on our common stock. We currently intend to retain any future earnings and do not
expect to pay any cash dividends on our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors and will be
dependent on a number of factors, including our earnings, capital requirements and overall financial conditions. In addition, the terms of our equipment loan agreement with Silicon Valley Bank limit
our ability to pay dividends. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If you invest in our common stock in this offering, your interest will be diluted immediately to the extent of the difference between
the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering. Our pro forma net
tangible book value as of September&nbsp;30, 2011 was $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, or $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share of common stock. Pro
forma net tangible book value per share represents the
amount of our total tangible assets less our total liabilities, divided by the number of shares of common stock outstanding as of September&nbsp;30, 2011, after giving effect to the conversion of
all outstanding shares of our convertible preferred stock into an aggregate of 39,134,535 shares of our common stock immediately upon the completion of this offering. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;After
giving effect to the sale by us of&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares of common stock in this offering at an assumed initial public offering price of
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share, which is the
midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses
payable by us, our pro forma as adjusted net tangible book value as of September&nbsp;30, 2011 would have been approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;million, or approximately
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per
share. This amount represents an immediate increase in pro forma net tangible book value of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share to our existing stockholders and an immediate dilution in pro forma net
tangible
book value of approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;per share to new investors purchasing shares of common stock in this offering at the assumed initial public offering price, or approximately

derived the consolidated statements of operations data for the years ended December&nbsp;31, 2008, 2009 and 2010, and the consolidated balance sheet data as of December&nbsp;31,
2009 and 2010 from our audited consolidated financial statements included elsewhere in this prospectus. We derived the consolidated statements of operations data for the years ended
December&nbsp;31, 2006 and 2007 and the consolidated balance sheet data as of December&nbsp;31, 2006, 2007 and 2008 from our audited financial statements not included in this prospectus. The
unaudited consolidated statements of operations data for the nine months ended September&nbsp;30, 2010 and 2011, and the unaudited consolidated balance sheet data as of September&nbsp;30, 2011,
are derived from our unaudited consolidated financial statements included elsewhere in this prospectus. Our unaudited consolidated financial statements have been prepared on the same basis as our
audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which consist only of normal recurring adjustments, necessary for the fair
statement of those unaudited consolidated financial statements. Our historical results are not necessarily indicative of the results to be expected in the future, and the results for the nine months
ended September&nbsp;30, 2011 are not necessarily indicative of operating results to be expected for the full year ending December&nbsp;31, 2011 or any other period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Overview  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most
sensitive data. Our security-as-a-service platform is comprised of an integrated suite of on-demand data protection solutions, including threat
protection, regulatory compliance, archiving and governance, and secure communication. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
were founded in 2002 to provide a unified solution to help enterprises address their growing data security requirements. Our first solution was commercially released in 2003 to combat
the burgeoning problem of spam and viruses and their impact on corporate email systems. As the threat environment has continued to evolve, we have dedicated significant resources to meet the ongoing
challenges that this highly dynamic environment creates for our customers. In addition, we have invested significantly to expand the breadth of our data protection platform: </FONT></P>

critical data. These Data Loss Prevention, or DLP, solutions apply our proprietary machine learning and deep content inspection technologies to screen outbound email to prevent the theft or
inadvertent loss of sensitive or confidential information.  </FONT> <FONT SIZE=2>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
business is based on a recurring revenue model. Our customers pay a subscription fee to license the various components of our
security-as-a-service platform for a contract term that is typically one to three years. At the end of the license term, customers may renew their subscription and
in each year since the launch of our first solution in 2003, we have retained over 90% of our customers. A growing number of our customers increase their annual subscription fees after their initial
purchase by broadening their use of our platform or by adding more users. As our business has grown, our subscription revenue has increased as a percentage of our total revenue, from 81% of total
revenue in the year ended December&nbsp;31, 2008 to 89% in the nine months ended September&nbsp;30, 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
market and sell our solutions to large and mid-sized customers both directly through our field and inside sales teams and indirectly through a hybrid model where our sales
organization actively assists our network of distributors and resellers. We also derive a lesser portion of our revenue from the license of our solutions to strategic partners who offer our solutions
in conjunction with one or more of their own products or services. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
invoice our customers for the entire contract amount at the start of the term. The majority of these invoiced amounts are treated as deferred revenue on our consolidated balance sheet
and are recognized ratably over the term of the contract. We invoice our strategic partners on a monthly basis, and the associated fees vary based upon the level of usage during the month by their
customers. These amounts are recognized as revenue at the time of invoice. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
solutions are designed to be implemented, configured and operated without the need for any training or professional services. For those customers that seek to develop deeper
expertise in the use of our solutions or would like assistance with complex configurations or the importing of data, we offer various training and professional services. In some cases, we provide a
hardware appliance to those customers that elect to host elements of our solution behind their firewall. Increasing adoption of virtualization in the data center has led to a decline in the sales of
our hardware appliances and a shift towards our software-based virtual appliances, which are delivered as a download via the Internet. Our hardware and services offerings carry lower margins and are
provided as a courtesy to our customers. The revenue derived from these offerings has declined from 19% of total revenue in the year ended December&nbsp;31, 2008 to 11% of total revenue in the nine
months ended September&nbsp;30, 2011. We view this trend as favorable to our business and expect the overall proportion of total revenue derived from these offerings to continue to gradually
decline. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
substantial majority of our revenue is derived from our customers in North America. We believe the markets outside of North America offer an opportunity for growth and we intend to
make additional investments in sales and marketing to expand in these markets. Customers from outside of North America represented 19% of total revenue for the nine months ended September&nbsp;30,
2011 and, 16%, 19% and 17% for the years ended December&nbsp;31, 2010, 2009 and 2008, respectively. As of September&nbsp;30, 2011, we had approximately 2,400 customers around the world, including
24 of the Fortune 100. No single partner or customer accounted for more than 10% of our total revenue in 2008, 2009 or 2010 or the nine months ended September&nbsp;30, 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
majority of costs associated with generating customer agreements are incurred up front. These upfront costs include direct incremental sales commissions, which are recognized upon
the billing of the contract. Although we expect customers to be profitable over the duration of the customer relationship, these upfront costs may exceed related revenue in earlier periods.
Accordingly, an increase in the mix of new customers as a percentage of total customers would likely negatively impact our operating results. On the other hand, we expect that an increase in the mix
of existing customers as a percentage </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>of
total customers would positively impact our operating results. As we accumulate customers that continue to renew their contracts, we anticipate that our mix of existing customers will increase. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To
date, our customers have primarily used our solutions in conjunction with email messaging content. We have developed solutions to address the new and evolving messaging solutions such
as social media and file sharing applications, but these solutions are relatively nascent. If customers increase their use
of these new messaging solutions in the future, we anticipate that our growth in revenue associated with email messaging solutions may slow over time. Although revenue associated with our social media
and file sharing applications has not been material to date, we believe that our ability to provide security, archiving, governance and discovery for these new solutions will be viewed as valuable by
our existing customers, enabling us to derive revenue from these new forms of messaging and communication. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;While
the majority of our current and prospective customers run their email systems on premise, we believe that there is a trend for large and mid-sized enterprises to migrate these
systems to the cloud. While our current revenue derived from customers using cloud-based email systems is approximately 10% of our total revenue, many of these cloud-based email solutions offer some
form of threat protection and governance services, potentially mitigating the need for customers to buy these capabilities from third parties such as ourselves. We believe that we can continue to
provide security, archiving, governance, and discovery solutions that are differentiated from the services offered by cloud-based email providers, and as such our platform will continue to be viewed
as valuable to enterprises once they have migrated their email services to the cloud, enabling us to continue to derive revenue from this new trend toward cloud-based email deployment models. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
are currently in the midst of a significant investment cycle in which we have taken steps designed to drive future revenue growth and profitability. For example, we plan to build out
our infrastructure, develop our technology, offer additional security-as-a-service solutions, and expand our sales and marketing personnel both in North America and
internationally. Accordingly, we expect that our total cost of revenue and operating expenses will continue to increase in absolute dollars, limiting our ability to achieve and maintain positive
operating cash flow and profitability in the near term. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Key Metrics  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We regularly review a number of metrics, including the following key metrics presented in the unaudited table below, to evaluate our
business, measure our performance, identify trends in our business, prepare financial projections and make strategic decisions. Many of these key metrics, such as adjusted subscription gross profit
and billings, are non-GAAP measures. This non-GAAP information is not necessarily comparable to non-GAAP information of other companies. Non-GAAP
information should not be viewed as a substitute for, or superior to, net loss prepared in accordance with GAAP as a measure of our profitability or liquidity. Users of this financial information

 <P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subscription revenue.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Subscription revenue represents the recurring subscription fees paid by our customers and recognized as revenue
during the
period for the use of our security-as-a-service platform, typically licensed for one to three years at a time. We consider subscription revenue to be a key business
metric because it reflects the recurring aspect of our business model and is the primary driver of growth for our business over time. The consistent growth in subscription revenue over the past
several years has resulted from our
ongoing investment in sales and marketing personnel, our efforts to expand our customer base, and our efforts to broaden the use of our platform with existing customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Adjusted subscription gross profit.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Adjusted subscription gross profit is a non-GAAP financial measure that we calculate as the gross
profit generated by our subscription revenue, adjusted to exclude stock-based compensation and the amortization of intangibles related to prior acquisitions. We believe that adjusted subscription
gross profit provides useful information to investors in understanding and evaluating our operating results in the same manner as our management and board of directors. This metric represents the
gross profit on our recurring subscription revenue and is directly related to our ability to generate profitability. Adjusted subscription gross profit, when measured as a percentage of subscription
revenue, improved from 64% during the nine months ended September&nbsp;30, 2010 to 72% during the same period in 2011. These improvements resulted from our ongoing efforts to reduce our cost of
subscription revenue through the replacement of technology licensed from third parties with our own proprietary technology in conjunction with improved operating leverage on our data center
infrastructure. Improvements in the gross profit of these subscription services enhance our ability to drive positive cash flow and profitability for our business overall. For more information about
adjusted subscription gross profit, see "Summary Consolidated Financial Information&#151;Reconciliation of Non-GAAP Financial Measures." </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Billings.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Billings is a non-GAAP financial measure that is a direct reflection of our overall sales activity in the period. Billings can
be derived by adding the change in the deferred revenue between the start and end of the period to the revenue recognized in the same time frame. Billings consist of all amounts invoiced to customers
for non-cancelable sales transactions and hence are important as they correspond directly to our near-term cash flow. However, trends in billings are not directly correlated to trends in
revenue except when measured over longer periods of time, as billings are affected by a combination of factors including the timing of renewals, the sales of our solutions to both new and existing
customers, the relative duration of contracts sold, and the relative amount of business derived from strategic partners. Each of these elements has unique characteristics in the relationship between
billings and revenue, and as such our billings activity is not closely correlated to revenue over shorter </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Revenue  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We derive our revenue primarily through the license of various solutions and services on our
security-as-a-service platform on a subscription basis, supplemented by the sales of training, professional services and hardware depending upon our customers'
requirements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subscription.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;We license our platform and its associated solutions and services on a subscription basis. The fees are charged on a per
user, per year
basis. Subscriptions are typically one to three years in duration. We invoice our customers upon signing for the entire term of the contract. The invoiced amounts billed in advance are treated as
deferred revenue on the balance sheet and are recognized ratably, in accordance with the appropriate revenue recognition guidelines, over the term of the contract (see &#151;Critical Accounting
Policies). We also derive a portion of our subscription revenue from the license of our solutions to strategic partners. We bill these strategic partners monthly. As our business has grown, our
subscription revenue has increased as a percentage of our total revenue, from 81% of total revenue in the year ended December&nbsp;31, 2008 to 89% in the nine months ended September&nbsp;30, 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Hardware and services.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;We provide hardware appliances as a convenience to our customers and as such it represents a small part of our
business. Our
solutions are designed to be implemented, configured and operated without the need for any training or professional services. For those customers that seek to develop deeper expertise in the use of
our solutions or would like assistance with complex configurations or the importing of data, we offer various training and professional services. We typically invoice the customer for hardware at the
time of shipment. Effective January&nbsp;1, 2011, we adopted the revenue recognition guidance of Accounting Standards Update (ASU) 2009-13 and ASU 2009-14, which mandate that
our revenue derived from the sale of hardware be recognized at the time of shipment. Prior to the adoption of this new accounting guidance, hardware revenue was recognized ratably over the duration of
the contract. We typically invoice customers for services at the time the order is placed and recognize this revenue ratably over the term of the contract. On occasion, customers may retain us for
special projects such as archiving import and export services; these types of services are recognized upon completion of the project. The revenue derived from these hardware and services offerings has
declined from 19% of total revenue in the year ended December&nbsp;31, 2008 to 11% of total revenue in the nine months ended September&nbsp;30, 2011. We view this
trend as favorable to our business and expect the overall proportion of revenue derived from these offerings to continue to decline gradually. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Total Cost of Revenue  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cost of Subscription Revenue.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Cost of subscription revenue primarily includes personnel costs, consisting of salaries, benefits,
bonuses, and
stock-based compensation, for employees who provide support services to our customers and operate our data centers. Other costs include fees paid to contractors who supplement our support and data
center personnel; expenses related to the use of third-party data centers in both the United States and internationally; depreciation of data center equipment; amortization of licensing fees and
royalties paid for the use of third-party technology; amortization of capitalized research and development costs; and the amortization of intangible assets related to prior acquisitions. Our cost of
subscription revenue has declined in recent periods as a percentage of its associated revenue as we have replaced third-party licensed technology with our proprietary technology, and we expect the
benefit of these initiatives to continue in future periods. </FONT></P>

training and
professional services to our customers as well as the cost of server hardware shipped to our customers that we procure from third parties and configure with our software solutions. Effective
January&nbsp;1, 2011, in conjunction with the adoption of the new revenue recognition guidance, the cost of hardware is expensed at the time of shipment. Prior to the adoption of this new guidance,
these hardware costs were recognized ratably over the duration of the contract with which they were sold. Our cost of hardware and services as a percentage of its associated revenue has been
relatively consistent from period to period in the past, but with the adoption of our new accounting guidance we expect that it may gradually increase as a percentage of hardware and services revenue
in future periods. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Operating Expenses  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our operating expenses consist of research and development, sales and marketing, and general and administrative expenses. Personnel
costs, which consist of salaries, benefits, bonuses, and stock-based compensation, are the most significant component of our operating expenses. Our headcount increased from 158 employees on
December&nbsp;31, 2007 to 348 employees as of September&nbsp;30, 2011. As a result of this growth in headcount, operating expenses have increased significantly over these periods. We expect
personnel costs to continue to increase in absolute dollars as we hire new employees to continue to grow our business. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Research and Development.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Research and development expenses include personnel costs, consulting services and depreciation. We expect to
continue to
devote substantial resources to research and development in an effort to continuously improve our existing solutions as well as to develop new offerings. We believe that these investments are
necessary to maintain and improve our competitive position. Our research efforts include both software developed for our internal use on behalf of our customers as well as software elements to be used
by our customers in their own facilities. To date, for software developed for internal use on behalf of our customers, we have capitalized costs of approximately $0.4&nbsp;million, all of which
occurred in the nine months ended September&nbsp;30, 2011, and will be amortized as cost of subscription revenue over a two-year period. Based on our current plans, we expect to capitalize a similar
portion of our development costs in the future. For the software developed for use on our customers' premises, the costs associated with the development work between technological feasibility and the
general availability has not been material and as such we have not capitalized any of these development costs to date. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales and Marketing.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Sales and marketing expenses include personnel costs, sales commissions, and other costs including travel and
entertainment,
marketing and promotional events, public relations and marketing activities. All of these costs are expensed as incurred, including sales commissions. These costs also include amortization of
intangible assets as a result of our past acquisitions. We plan to continue to invest in growing our sales and marketing operations, both domestically and internationally. Our sales personnel are
typically not immediately productive, and therefore the increase in sales and marketing expenses we incur when we add new sales representatives is not immediately offset by increased revenue and may
not result in increased revenue over the long-term if these new sales people fail to become productive. The timing of our hiring of new sales personnel and the rate at which they generate
incremental revenue will affect our future financial performance. We expect that sales and marketing expenses will continue to increase in absolute dollars and be among the most significant components
of our operating expenses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;General and Administrative.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;General and administrative expenses include personnel costs, consulting
services, audit fees, tax services, legal expenses and other general corporate items. We expect our general and administrative expenses to increase in future periods as we continue to expand our
operations, hire additional personnel and transition from being a private company to a public company. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The provision for income taxes is related to certain state and foreign income taxes. As we have incurred operating losses in all
periods to date and recorded a full valuation allowance against our deferred tax assets, we have not historically recorded a provision for federal income taxes. Realization of any of our deferred tax
assets depends upon future earnings, the timing and amount of which are uncertain. Utilization of our net operating losses may be subject to substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code and similar state provisions. An analysis was conducted through 2009 to determine whether an ownership change had occurred since inception. The
analysis indicated that although an ownership change occurred in a prior year, the net operating losses and research and development credits would not expire before utilization. In the event we have
subsequent changes in ownership, net operating losses and research and development credit carryovers could be limited and may expire unutilized. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cost of subscription revenue decreased $0.4&nbsp;million, or 2%, for the nine months ended September&nbsp;30, 2011 as compared to the same
period in 2010. The decrease in cost of subscription revenue was primarily attributable to a $0.9&nbsp;million decrease in royalty expense driven by the replacement of third-party licensed
technology with our proprietary technology, as well as improved economic terms associated with other ongoing licensing agreements. We expect that the combination of these two initiatives will also
continue to contribute to reduced royalty expenses in future periods. These savings were partially offset by increased data center costs of $0.3&nbsp;million associated with ongoing growth in usage
by new and existing customers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cost
of hardware revenue and services revenue increased $1.5&nbsp;million, or 49%, for the nine months ended September&nbsp;30, 2011 as compared to the same period in 2010. This
increase was primarily attributable to the adoption of the new revenue recognition guidance effective January&nbsp;1, 2011 under which costs from sales of hardware appliances are now recognized when
the associated hardware revenue is recognized. Accordingly, $1.1&nbsp;million of this cost increase was a result of the change in revenue recognition guidance while $0.2&nbsp;million was due to
the ratable recognition of deferred costs for hardware appliance sales closed prior to the adoption of the new revenue recognition guidance effective January&nbsp;1, 2011. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total other income (expense), net increased $0.4&nbsp;million for the nine months ended September&nbsp;30, 2011 as compared to the same period
in 2010. The change was primarily due to a decrease in interest expense as we continued to pay down our capital equipment loans, offset by a $0.2&nbsp;million adjustment to the accretion of interest
relating to the earn-out consideration from an acquisition that was recorded on a discounted basis. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subscription revenue increased $15.5&nbsp;million, or 37%, for 2010 as compared to 2009. This growth was primarily due to higher demand for our
solutions in North America, aided by improved economic conditions in that region over the prior period as well as our ongoing investments in sales and marketing. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Hardware
and services revenue grew $0.7&nbsp;million, or 12%, for 2010 as compared to 2009. This growth was primarily due to a modest increase in the sale of both hardware and
professional services. The relatively slow growth in hardware and services as compared to subscription revenue reflects the ongoing shift in deployment models towards our cloud-based and virtual
appliance solutions. </FONT></P>

and, to a lesser extent, internationally as our initial investments in sales and marketing outside of North America produced growth in revenue from those markets. </FONT></P>

of subscription revenue increased $7.2&nbsp;million, or 61%, for 2009 as compared to 2008. This increase was primarily due to increased demand for our subscription services, with
data center costs increasing $2.2&nbsp;million and depreciation and amortization by $1.5&nbsp;million. Headcount expansion in support of this growth resulted in $1.6&nbsp;million of additional
personnel costs. Amortization of developed technology increased $1.9&nbsp;million, which represents a full year of amortization expense related to an acquisition in June 2008. </FONT></P>

of hardware and services revenue decreased $0.5&nbsp;million, or 14%, for 2009 as compared to 2008. This resulted from the increasing deployment of our cloud-based services. </FONT></P>

commission expense, travel and entertainment and facilities related spending of $0.7&nbsp;million, $0.7&nbsp;million and $0.3&nbsp;million, respectively. </FONT></P>

other income (expense), net, decreased by $0.5&nbsp;million for 2009 as compared to 2008 primarily due to a reduction in interest income due to lower invested cash balances. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Liquidity and Capital Resources  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Since our inception, we have relied principally on sales of our preferred stock to fund our operating activities. To date, we have
raised $92.8&nbsp;million of equity capital. Additionally, we have utilized equipment lines to fund capital purchases. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
entered into a new equipment loan agreement with Silicon Valley Bank in April 2011 for an aggregate loan principal amount of $6.0&nbsp;million. Interest on the advances are equal to
prime rate plus 0.50%. As of September&nbsp;30, 2011, the interest rate on the advances was 4.50%. We have the ability to draw down on this equipment line through April&nbsp;19, 2012. Each drawn
amount is due 48 months after
funding. Borrowings outstanding under the equipment loan at September&nbsp;30, 2011 were $2.9&nbsp;million. Equipment financed under this loan arrangement is collateralized by the respective
assets underlying the loan. The loan includes a covenant that requires us to maintain cash and cash equivalents plus net accounts receivables of at least two times the amount of all outstanding
indebtedness. As of September&nbsp;30, 2011, we were in compliance with this financial covenant. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based
on our current level of operations and anticipated growth, we believe that our existing sources of liquidity will be sufficient to fund our operations for at least the next
12&nbsp;months. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, and the timing and extent of
spending to support product development efforts and expansion into new territories, and the timing of introductions of new features and enhancements to our solutions. To the extent that existing cash
and cash equivalents and cash from operations are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. We may also seek
to invest in or acquire complementary businesses, applications or technologies, any of which could also require us to seek additional equity or debt financing. Additional funds may not be available on
terms favorable to us or at all. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We

provisions is generally limited to the total amount paid by the customer under the applicable customer agreement. However, certain indemnification provisions potentially expose us to losses in excess
of the aggregate amount paid to us by the customer under the applicable customer agreement. No material claims have been made against us pursuant to these indemnification provisions to date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Off-Balance Sheet Arrangements  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During the periods presented, we did not have, nor do we currently have, any relationships with unconsolidated entities or financial
partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet
arrangements or other contractually narrow or limited purposes. We are therefore not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in those types of
relationships. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Quantitative and Qualitative Disclosures about Market Risk  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our
business. These risks primarily include interest rate, foreign exchange and inflation risks, as well as risks relating to changes in the general economic conditions in the countries where we conduct
business. To reduce certain of these risks, we monitor the financial condition of our large clients and limit credit exposure by collecting in advance and setting credit limits as we deem appropriate.
In addition, our investment strategy has been to invest in financial instruments that are highly liquid and readily convertible into cash with maturity dates within three months from the date of
purchase. To date, we have not used derivative instruments to mitigate the impact of our market risk exposures. We have also not used, nor do we intend to use, derivatives for trading or speculative
purposes. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Interest Rate Risk  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are exposed to market risk related to changes in interest rates. Our investments are considered cash equivalents and primarily
consist of money market funds, corporate debt securities and a certificate of deposit. As of September&nbsp;30, 2011, we had cash, cash equivalents, and short-term investments of
$12.1&nbsp;million. The carrying amount of our cash, cash equivalents and short-term investments reasonably approximates fair value, due to the short maturities of these investments. The
primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We do not enter into investments
for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our
investments. Due to the short-term nature of our investment portfolio, we believe only dramatic fluctuations in interest rates would have a material effect on our investments. As such we
do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of September&nbsp;30, 2011 we had borrowings outstanding with principal amounts of $3.0&nbsp;million. Our outstanding long-term borrowings consist of fixed and
variable interest rate financial instruments. The interest rates of our borrowings range from 2.9% to 10.6%. A hypothetical 10% increase or decrease in interest rates relative to our current interest
rates would not have a material impact on the fair values of all of our outstanding borrowings. Changes in interest rates would, however, affect operating results and cash flows, because of the
variable rate nature of our borrowings. A hypothetical 10% increase or decrease in interest rates relative to interest rates at December&nbsp;31, 2010 would result in an insignificant impact to
interest expense for 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Foreign Currency Risk  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our sales to international customers are generally U.S. dollar-denominated. As a result, there are no significant foreign currency
gains or losses related to these transactions. The functional currency for our wholly owned foreign subsidiaries is the U.S. dollar. Accordingly, the subsidiaries remeasure monetary assets and
liabilities at period-end exchange rates, while nonmonetary items are remeasured at historical rates. Income and expense accounts are remeasured at the average exchange rates in effect </FONT></P>

respectively. For the nine months ended September&nbsp;30, 2011, however, there was a net transaction gain of $93,000. Transaction gains and losses are included in other income (expense), net. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
our international operations grow, our risks associated with fluctuation in currency rates will become greater, and we will continue to reassess our approach to managing this risk. In
addition, currency fluctuations or a weakening U.S. dollar can increase the costs of our international expansion. To date, we have not entered into any foreign currency hedging contracts, since
exchange rate fluctuations have not had a material impact on our operating results and cash flows. Based on our current international structure, we do not plan on engaging in hedging activities in the
near future. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B><I> Inflation Risk  </I></B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We do not believe that inflation has had a material effect on our business, financial condition or results of operations. Nonetheless,
if our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm
our business, financial condition and results of operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Critical Accounting Policies  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our management's discussion and analysis of our financial condition and results of operations are based on our consolidated financial
statements, which have been prepared in accordance with GAAP. GAAP requires us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the dates of
the consolidated financial statements, the disclosure of contingencies as of the dates of the consolidated financial statements, and the reported amounts of revenue and expenses during the periods
presented. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities. If actual results or events differ materially from those contemplated by us in making these estimates, our reported financial condition
and results of operations for future periods could be materially affected. See "Risk Factors" for certain matters that may affect our future financial condition or results of operations. An accounting
policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are uncertain at the time the estimate is made, if different estimates
reasonably could have been used, or if the changes in estimate that are reasonably likely to occur could materially impact the financial statements. Our management has discussed the development,
selection and disclosure of these estimates with the audit committee of our board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We derive our revenue primarily from two sources: (1)&nbsp;subscription revenue for rights related to the use of our
security-as-a-service platform and (2)&nbsp;hardware, training, and professional services revenue provided to customers related to their use of our platform.
Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to three years, and consists of (i)&nbsp;subscription fees from
the licensing of our security-as-a-service platform, (ii)&nbsp;subscription fees for access to the on-demand elements of our platform and
(iii)&nbsp;subscription fees for the right to access our customer support services. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
apply the provision of Accounting Standard Codification (ASC) 985-605, "Software Revenue Recognition," and related interpretations, to all transactions involving the
licensing of software, as well as related support, training, and other professional services. ASC 985-605 requires revenue earned on software arrangements involving multiple elements such
as software license, support, training, and other professional services to be allocated to each element based on the relative fair values of these elements. The fair value of an element must be based
on vendor-specific objective evidence (VSOE) of fair value. VSOE of fair value of each element is based on the price charged when the element is sold separately. Revenue is recognized when all of the
following criteria are met as set forth in ASC 985-605: </FONT></P>

associated professional services. Once the subscription services and the associated professional services have commenced, the entire fee from the arrangement is recognized ratably over the remaining
period of the arrangement. If the professional services are essential to the functionality of the subscription, then the revenue recognition does not commence until such services are completed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Concurrently,
the FASB amended the accounting guidance for revenue recognition (ASU 2009-14) to exclude hardware appliances containing software components and hardware
components that function together to deliver the hardware appliance's essential functionality from the scope of the software revenue recognition guidance of ASC 985-605. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior
to the adoption of ASU 2009-14, revenue derived from hardware appliance sales were recognized based on the software revenue recognition guidance. We could not establish
VSOE of fair value for the undelivered elements in the arrangement, and therefore the entire fee from the arrangement was recognized ratably over the contractual term of the agreement. In addition, we
were unable to establish VSOE of fair value of our hosted on-demand service agreements, and therefore the entire fee for the agreement was recognized ratably over the contractual term of
the agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of the adoption of this new accounting guidance, revenue derived from our subscription services and hardware appliance sales are no longer subject to industry-specific
software revenue recognition guidance. For all arrangements within the scope of the new guidance, including our hosted on-demand services, we evaluate each element in a multiple element
arrangement to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when the delivered item has standalone value and delivery of the
undelivered element is probable and within our control. Revenue derived from the licensing of the security-as-a-service platform continue to be accounted for in
accordance with the industry specific revenue recognition guidance. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When
we are unable to establish the selling price of our non-software deliverables using VSOE or TPE, we use BESP in our allocation of arrangement consideration. The
objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We determine BESP for an individual element within a multiple
element revenue arrangement using the same methods utilized to determine the selling price of an element sold on a standalone basis. We estimate the selling price for our subscription solutions by
considering internal factors such as historical pricing practices and we estimate the selling price of our hardware and services using a combination of our historical costs paired with external
measurements regarding the pricing of similar products and services in similar industries. As there is a significant amount of judgment when determining BESP, we regularly review all of our
assumptions and inputs around BESP and maintain internal controls over the establishment and updates of these estimates. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Hardware
appliance revenue is recognized upon shipment. Subscription and support revenue are recognized over the contract period commencing on the start date of the contract.
Professional services and training, when sold with hardware appliances or subscription and support services, are accounted for separately when those services have standalone value. In determining
whether professional services and training services can be accounted for separately from subscription and support services, we consider the following factors: availability of the services from other
vendors, the nature of the services, and the dependence of the subscription services on the customer's decision to buy the professional services. If professional services and training do not qualify
for separate accounting, we recognize the professional services and training ratably over the contract term of the subscription services. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Delivery

this new accounting guidance, hardware revenue was recognized ratably over the duration of the contract. Accordingly, as of December&nbsp;31, 2010, our deferred revenue balance reflected amounts yet
to be recognized under our then-current accounting practices. These deferred amounts will continue to be recognized ratably under their original amortization schedules until the end of the associated
contract term. As such, until the end of these contract periods, we will recognize hardware revenue both from sales in prior periods subject to the original accounting guidance as well as from sales
in current periods subject to the new accounting guidance, with the principal impact being in 2011 and to a lesser extent 2012 and future periods. Given the marginal contribution toward profitability
of our hardware appliances, we do not expect this transition to contribute materially toward our profitability. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective January&nbsp;1, 2006, we adopted ASC&nbsp;718, which requires non-public companies that used the minimum
value method under ASC&nbsp;718 for either recognition or pro forma disclosures to apply ASC&nbsp;718 using the prospective-transition method. In accordance with ASC&nbsp;718, we recognize the
compensation cost of employee stock-based awards granted subsequent to December&nbsp;31, 2005 in the statement of operations using the straight-line method over the vesting period of the
award. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of each stock option grant date, we considered the fair value of the underlying common stock, determined as described below, in order to
establish the options exercise price. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
there has been no public market for our common stock prior to this offering, and therefore a lack of company-specific historical and implied volatility data, we have determined the
share price volatility for options granted based on an analysis of reported data for a peer group of companies that granted options with substantially similar terms. We analyzed a population of
possible comparable companies and selected those for our peer group that we considered to be the most comparable to us in terms of industry business model, revenue, growth and gross profit margins.
The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies for a period equal to the expected life of the
option. We intend to continue to consistently apply this process using the same or similar entities until a sufficient amount of historical information regarding the volatility of our own share price
becomes available, or unless circumstances change such that the identified entities are no longer similar to us. In this latter case, more suitable entities whose share prices are publicly available
would be utilized in the calculation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
expected life of options granted has been determined utilizing the "simplified" method as prescribed by the SEC's Staff Accounting Bulletin, or SAB, No.&nbsp;107, Share-Based
Payment , or SAB&nbsp;107. The risk-free interest rate is based on a daily treasury yield curve rate whose term is consistent with the expected life of the stock options. We have not,
historically, paid and, in the future, do not anticipate paying cash dividends on our shares of common stock and therefore, the expected dividend yield is assumed to be zero. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, ASC&nbsp;718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
We apply an estimated forfeiture rate based on our historical forfeiture experience. </FONT></P>

our valuations we calculated the enterprise value by applying both the market approach and the income approach. In the market approach the valuations and outcomes of comparable peer
companies in the public market were reviewed. The income approach consists of a discounted cash flow analysis. The methodology we use derives equity values utilizing a probability-weighted expected
return method. Under this approach, various potential liquidity events are identified and each possible outcome is assigned a probability based on discussion with our management. For each of the
possible events, a range of future equity values is estimated based on both the market and income approaches where applicable, applying various possible dates for each event. The timing of these
events is based on discussion with our management. For each future equity liquidity value scenario, the rights and preferences of each stockholder class are considered in order to determine the
appropriate allocation of value to common shares. The value of each common share is then multiplied by a discount factor derived from the calculated discount rate and the expected timing of the event.
The value per common share, taking into account sensitivities to the timing of the event, is then multiplied by an estimated probability for each of the possible events. The calculated value per
common share under a private company scenario is then discounted for a lack of marketability. A probability-weighted value per share </FONT></P>

compared to the
preceding quarter, and both profitability and cash flow were negative. Given that these grants occurred within a span of approximately 60 days and there were no material changes to the business during
that time, we used the same sets of assumptions in assessing the valuation for all three dates. For these grants, we determined our valuation using the income and market approaches with 60% weighting
assigned to the market approach and 40% assigned to the income approach. We then applied the option pricing method, where the rights of the various holders of preferred and common stock are evaluated
against these two valuations in order to arrive at a fair value associated with the common stock. In addition, this analysis used a 25% lack of marketability discount. Based on all of these factors,
our board of directors determined a fair value of our common stock to be $1.94 per share at each respective date. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;July&nbsp;30, 2010.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;In July 2010, our total revenue continued to grow at a modest pace of 4% compared to the preceding quarter during
the early
stages of the economic recovery. In estimating the fair value as of July&nbsp;30, 2010, key assumptions included a time to liquidity of greater than 12&nbsp;months for an initial public offering
or a strategic merger or sale of the company, with the expected outcomes weighted 40% towards an initial public offering, 30% towards a strategic merger or sale, 25% towards remaining a private
company and 5% towards a liquidation scenario. In addition, this analysis used a 25% lack of marketability discount as there was not a perceived change in the likelihood of a liquidation event. Based
on all these factors, the board of directors determined a fair value of our common stock to be $2.49 per share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;October&nbsp;28, 2010.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;In October 2010, our total revenue continued to grow and we generated cash flow from operations for the first
time since the
economic downturn. In estimating the fair value as of October&nbsp;28, 2010, key assumptions included a time to liquidity of greater than 12 months in terms of an initial public offering, strategic
merger or sale of the company, with the expected outcomes weighted 40% towards an initial public offering, 30% towards a strategic merger or sale, 25% towards remaining a private company and 5%
towards a liquidation scenario. In addition, this analysis used a 20% lack of marketability discount. Despite our 4% quarter over quarter revenue growth, a pullback in stock valuations as evidenced by
a decline in the S&amp;P&nbsp;500 index of approximately 10% over this same period of time resulted in a decline in valuations for our peer group. Based on all these factors, the board of directors
determined a fair value of our common stock to be $2.44 per share. </FONT></P>

marketability discount to 17.5%, given the promising acceleration in the growth of our business and positive cash flow. The expected time to strategic merger or sale in the event of not completing a
public offering was still deemed to be greater than 12&nbsp;months. The expected outcomes were weighted 40% towards an initial public offering, 55% towards a strategic merger or sale and 5% towards
a liquidation scenario. Based on all these factors, the board of directors determined a fair value of our common stock to be $2.69 per share. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amended guidance eliminates one of the
presentation options provided by current U.S.&nbsp;GAAP that is to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, it
gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of
comprehensive income or in two separate but consecutive statements. This guidance will be effective for reporting periods beginning after December&nbsp;15, 2011 and will be applied retrospectively.
We do not expect that this guidance will have an impact on our financial position, results of operations or cash flows. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
September 2011, the FASB issued amended guidance relating to the goodwill impairment test. The guidance provides that an entity first assess qualitative factors to determine whether
it is necessary to perform the two-step quantitative goodwill impairment test. Under that option, an entity no longer would be required to calculate the fair value of a reporting unit
unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The guidance also includes examples of the
types of events and circumstances to consider in conducting the qualitative assessment. The guidance will be effective for annual and interim goodwill impairment tests performed for fiscal years
beginning after December&nbsp;15, 2011. Early adoption is permitted. We are currently evaluating this amended guidance but we do not expect that it will have an impact on our consolidated financial
statements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most sensitive data. Our security-as-a-service platform is comprised of
an integrated suite of on-demand data protection solutions, including threat protection, regulatory compliance, archiving and governance, and secure communication. Our solutions are built
on a flexible, cloud-based platform and leverage a number of proprietary technologies, including big data analytics, machine learning, deep content inspection, secure storage and advanced encryption,
to address today's rapidly changing threat landscape. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
fundamental shift in the sources of cyber crime, from hackers to organized crime and governments, combined with the emergence of international data trafficking, are driving an
unprecedented wave of targeted, malicious attacks designed to steal valuable information. At the same time, the growth of business-to-business collaboration, as well as the consumerization of IT and
the associated adoption of mobile devices and unmanaged Internet-based applications, have proliferated sensitive data and reduced the effectiveness of many existing security products. These factors
have contributed to an increasing number of severe data breaches and expanding regulatory mandates, all of which have accelerated demand for effective data protection and governance solutions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
platform addresses this growing challenge by not only protecting data as it flows into and out of the enterprise via on-premise and cloud-based email, instant messaging, social media
and other web-based applications, but also securely archiving these communications for compliance and discovery. We address four important problems for the

targeted.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;In recent years, data security threats have become more sophisticated as professional criminals, governments and "hacktivists"
have targeted sensitive information and a market has emerged for stolen data. As this transition has happened, threats have shifted away from generic malware and high-volume spam to more
targeted attacks focused on high-value data such as credit card numbers, login credentials, health care records, social security numbers, financial information and intellectual property.
Once stolen, this data often is used in a wide range of illegal activity, including insurance fraud, banking theft, identity theft, credit card fraud and insider trading. Gartner estimates that
through the end of 2015, financially motivated attacks will continue to be the source of more than 70% of the most damaging cyber threats.* Seemingly harmless data such as an email address is also
leveraged in conjunction with personal information from social networking sites to launch targeted "spear phishing" attacks&nbsp;-&nbsp;emails designed to look authentic and trick the
end-user into divulging sensitive data or clicking on a malicious web link to gain access to information protected within corporate networks. Spear phishing attacks are believed to have
been used in a number of recent high profile data breaches.  </FONT></DD></DL>

designed primarily to stop large-scale spam and virus attacks that emerged in the early and mid-2000s. The techniques these systems employ to detect and defend against broad attacks, such
as signature databases of known malicious code, IP-reputation for spam generating sites and "honey pots" or spam-traps to identify new threats, are often ineffective against
today's targeted attacks. Cybercriminals are now employing advanced, targeted attacks such as "spear phishing" designed to defeat these legacy defenses by using URLs and shortened URLs to avoid
signature detection, leveraging compromised accounts to bypass reputation systems, and directly targeting known valid recipients to avoid detection by "honey pots."  </FONT> <FONT SIZE=2>

deployed a collection of specialized products and associated hardware for spam and anti-virus protection, compliance enforcement, data loss protection, content encryption, secure mobile

response that coordinates protection against inbound threats with remediation efforts to prevent resulting outbound risks. In addition, existing products are largely reactive, employing either passive
auditing or basic blocking techniques, and do not enable secure communications or proactive data governance in real time. For example, traditional email security offerings will typically deposit even
the most serious of threats in the end-user quarantine, thereby relying on end-users to refrain from opening malicious messages specifically stored in this repository for their review and
disposition by the user.  </FONT> <FONT SIZE=2>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A global company that offers consumer products, manufacturing and logistics services in more than 80 countries and territories
worldwide had been using a legacy security solution and, as part of its regular assessments of its messaging environment and security stance, was looking for solutions that offered superior security,

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The company chose to deploy Proofpoint Enterprise Protection, originally deployed on-premise using hardware appliances. As

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain
of our competitors have greater sales, marketing and financial resources, more extensive geographic presence and greater name recognition than we do. We may face future
competition in our markets from other large, established companies, as well as from emerging companies. In addition, we expect that there is likely to be continued consolidation in our industry that
could lead to increased price competition and other forms of competition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Intellectual Property  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We rely on a combination of trade secrets, patents, copyrights and trademarks, as well as contractual protections, to establish and
protect our intellectual property rights and protect our proprietary technology. As of September&nbsp;30, 2011, we had 15 patents and six patent
applications. We have a number of registered and unregistered trademarks. We require our employees, consultants and other third parties to enter into confidentiality and proprietary rights agreements
and control access to software, documentation and other proprietary information. Although we rely on intellectual property rights, including trade secrets, patents, copyrights and trademarks, as well
as contractual protections to establish and protect our proprietary rights, we believe that factors such as the technological and creative skills of our personnel, creation of new modules, features
and functionality, and frequent enhancements to our solutions are more essential to establishing and maintaining our technology leadership position. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Despite
our efforts to protect our proprietary technology and our intellectual property rights, unauthorized parties may attempt to copy or obtain and use our technology to develop
products with the same functionality as our solution. Policing unauthorized use of our technology and intellectual property rights is difficult. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
expect that software and other solutions in our industry may be subject to third-party infringement claims as the number of competitors grows and the functionality of products in
different industry segments overlaps. Any of these third parties might make a claim of infringement against us at any time. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><B> Employees  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of September&nbsp;30, 2011, we employed 348 people, including 153 in sales and marketing, 75 in operations, professional services,
training and customer support, 88 in product development, and 32 in a general and administrative capacity. As of such date, we had 263 employees in the United States and 85 employees internationally.
We also engage a number of temporary employees and consultants. None of our employees is represented by a labor union with respect to his or her employment with us. We have not experienced any work
stoppages and we consider our relations with our employees to be good. Our future success will depend upon our ability to attract and retain qualified personnel. Competition for qualified personnel
remains intense and we may not be successful in retaining our key employees or attracting skilled personnel. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Legal Proceedings  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;From time to time, we are involved in various legal proceedings arising from the normal course of business activities. We are not
presently a party to any litigation the outcome of which, we believe, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, operating
results, cash flows or financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
part of a pre-IPO due diligence review, we discovered a potential export violation involving the provision of web-based, email communication services to
end-users located in Iran through our Everyone.net service, which we acquired in October 2009. Neither of these suspected end users appears to have been a current customer of these
web-based email services since late 2010 or early 2011. Although we had ceased providing the services, we are making a voluntary submission to OFAC to report this potential violation. In
addition, we determined that after August 2008, we may have shipped a particular hardware appliance model to a limited number of international customers that, prior to shipment, may have required
either a one-time product review or application for an encryption registration number in lieu of such product review. We have since acquired the appropriate encryption registration number.
We are also making a voluntary submission to BIS to report this potential violation. Our investigation of these matters is still ongoing and it is possible that we may discover additional violations.
We are in the process of supplementing our existing systems and procedures designed to ensure that we do not have any such violations in the future. Although we are still in the early stages of
investigating these matters, it is possible these recent voluntary submissions could result in penalties, costs, and restrictions on export privileges, which could harm our operating results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Director Independence  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have applied to list our common stock on the NASDAQ Global Market. The listing rules of the NASDAQ Global Market require that a
majority of the members of our board of directors be independent. Our board of directors undertook a review of its composition and the independence of each director. Based upon information requested
from and provided by each director concerning his background, employment and affiliations, our board of directors determined that none of our non-employee directors has a relationship that
would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under the rules
of the NASDAQ Global Market. In making this determination, our board of directors considered the relationships that each non-employee director has with our company and all other facts and
circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. The
independence of our board committee members is discussed below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Board Leadership  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our board of directors is led by our chairman. The chairman of the board chairs all meetings of our board of directors, including
executive sessions. The chairman of the board also acts as liaison between the independent directors and management. We believe that having different people serving in the roles of chairman of the
board and Chief Executive Officer is an appropriate and effective organizational structure for our company at this time. Separating these positions allows our chairman of the board to lead the board
of directors in its fundamental role of providing advice to and independent oversight of management, while enabling our Chief Executive Officer to focus his time on our
day-to-day business. The board of directors further recognizes the commitment required to serve as our chairman, particularly as the board of directors' oversight
responsibilities continue to grow, as well as the time, effort and energy that our Chief Executive Officer is required to devote to his position. However, we also recognize that no single leadership
model is right for all companies at all times, and that depending on the
circumstances, other leadership models, such as having one person serving as both the chairman of the board and Chief Executive Officer, might become appropriate. Accordingly, the board of directors
anticipates periodically reviewing its leadership structure. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Committees of Our Board of Directors  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our board of directors has established an audit committee, a compensation committee and a nominating and governance committee. The
composition and responsibilities of each committee are described below. Members serve on these committees until their resignations or until otherwise determined by our board of directors. Our board of
directors has adopted a charter for each of these committees, which it believes complies with the applicable requirements of current NASDAQ Global Market rules. We intend to comply with future
requirements to the extent they are applicable to us. Following the closing of this offering, copies of the charters for each committee will be available on the investor relations portion of our
website. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Audit Committee  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our audit committee is currently comprised of Ms.&nbsp;Evan, who is the chair of the audit committee, and Mr.&nbsp;Ward. We
anticipate that a third director will be appointed to the audit committee prior to this offering. We believe that the composition of our audit committee prior to this offering, and our audit
committee's charter and functioning will comply with the requirements for independence under current NASDAQ Global Market and SEC rules and regulations. Each member of our audit committee is
financially literate as required by current NASDAQ Global Market listing standards. In addition, our board of directors has determined that Ms.&nbsp;Evan is an audit committee financial expert

to a policy adopted by our board of directors, each non-employee director who first becomes a member of our board of directors on or after the completion of this
offering will receive an initial option to purchase 75,000 shares of our common stock. At each annual meeting of our stockholders, each non-employee director will automatically be granted
an annual option grant to purchase 25,000 shares of our common stock if the non-employee director has served continuously as a member of our board of directors for at least six months.
Each initial stock option award granted to non-employee directors vests in equal annual installments over three years from the date of grant, the shares underlying which are exercisable at
a price per share equal to the fair market value of the stock on the date of grant. Each annual stock option award vests in full immediately prior to the first annual meeting of our stockholders to
occur after the date of grant. Each of these awards is immediately exercisable in full; however, any unvested shares issued upon exercise will be subject to a right of repurchase by us upon
termination of the director's service at a price per share equal to the fair market value of the stock on the date of grant, which right lapses in accordance with the vesting schedule described above.
The vesting of the awards
made to non-employee directors under the policy described above will accelerate and vest in full in the event of a change in control of our company. The awards will have
10-year terms and will terminate three months following the date the director ceases to be one of our directors or consultants or 12&nbsp;months following that date if the termination is
due to death or disability. In addition to the awards provided for above, non-employee directors are eligible to receive discretionary awards of stock options. All grants to
non-employee directors will be made on a discretionary basis under the 2012 Equity Incentive Plan. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Non-employee
directors receive no other form of remuneration, perquisites or benefits, but are reimbursed for travel, meal and other expenses incurred to attend meetings. The
following table provides information regarding stock options granted to our non-employee directors during 2010. Each of these options was granted with an exercise price equal to the fair
market value of our common stock on the date of grant and will vest in full 12&nbsp;months after the date of this prospectus. Other than reimbursement of reasonable travel and related expenses
incurred by non-employee directors in connection with their attendance at meetings of our board of directors and its committees, we did not pay any other fees, make any other equity or
non-equity awards to, or pay any other compensation to our non-employee directors in 2010. All compensation that we paid to Mr.&nbsp;Steele, our only employee director, is
set forth in the tables below under "Executive Compensation&#151;Executive Compensation Tables." No compensation was paid to Mr.&nbsp;Steele in his capacity as a director. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
refer to these executive officers collectively in this Compensation Discussion and Analysis and the related compensation tables as the "Named Executive Officers." </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Specifically,
this Compensation Discussion and Analysis provides an overview of our executive compensation philosophy, the overall objectives of our executive compensation program, and
each component of compensation that we provide. In addition, we explain how and why the compensation committee of our board of directors arrived at the specific compensation policies and decisions
involving our executive officers, including the Named Executive Officers listed in the Summary Compensation Table set forth below, during 2010. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Executive Compensation Philosophy and Objectives  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We operate in a highly competitive business environment, which is characterized by frequent technological advances, rapidly changing
market requirements, and the emergence of new market entrants. To successfully grow our business in this dynamic environment, we must continually develop and refine our solutions to stay ahead of
customer needs and challenges. To achieve these objectives, we need a highly talented and seasoned team of technical, sales, marketing, operations, and other business professionals. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
compete with many other companies in seeking to attract and retain a skilled management team. To meet this challenge, we have embraced a compensation philosophy of offering our
executive officers a competitive total compensation program that recognizes and rewards individual performance and contributions to our success, allowing us to attract, retain, and motivate talented
executives with the skills and abilities needed to drive our desired business results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our executive compensation consists of base salary, an annual cash bonus opportunity, sales commissions plans, equity compensation in
the form of stock options, and certain employee welfare benefits. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically,
the key component of our executive compensation program has been equity awards for shares of our common stock. As a privately-held company, we have emphasized
the use of equity to provide incentives for our executive officers to focus on the growth of our overall enterprise value and, correspondingly, to create value for our stockholders. We have used stock
options as our primary equity award vehicle for all of our employees. We believe that stock options offer our employees, including the Named Executive Officers, a valuable long-term
incentive that aligns their interests with the long-term interests of our stockholders. Going forward, we may introduce other forms of stock-based compensation awards, as we deem
appropriate, into our executive compensation program to offer our executive officers additional types of long-term equity incentives that further this objective. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
also offer cash compensation in the form of base salaries, annual cash bonus opportunities and sales commissions. Typically, we have structured our annual cash bonus opportunities to
focus on the achievement of specific short-term financial and strategic objectives that will further our longer-term growth objectives. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically,
we have used standard industry surveys, including the Radford High-Technology Executive Compensation Survey, particularly for companies with annual revenue of
up to $200&nbsp;million, to assist the compensation committee in establishing cash compensation levels for our executive officers with an emphasis on technology companies with a similar size, stage
of development, and growth potential. Using this information as a guideline, the compensation committee has emphasized remaining competitive in our market and differentiating total cash compensation
levels through the use of an annual cash bonus plan and sales commissions. Equity compensation has been delivered on a discretionary basis with the goal to retain top talent and align the interests of
our executive officers with the long-term interests of our stockholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have not adopted any formal policies or guidelines for allocating compensation between current and long-term compensation, between cash and non-cash
compensation, or among different forms of non-cash compensation. Instead, the compensation committee reviews each component of executive compensation separately and also takes into
consideration the value of each executive officer's compensation package as a whole and its relative size in comparison to our other executive officers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Role of the Compensation Committee  </I></FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Since 2004, the compensation committee has been responsible for evaluating, approving, and reviewing the compensation arrangements,
plans, policies, and programs for our executive officers, including the Named Executive Officers (other than our CEO), and directors, and overseeing our cash-based and equity-based
compensation plans. Generally, decisions with respect to the cash compensation of our executive officers have been made by the compensation committee, while decisions with respect to their equity
compensation awards have been made by our board of directors, based upon the recommendations of the compensation committee. In the case of our CEO's equity compensation awards, decisions have been
made by the independent members of our board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the beginning of each year, the compensation committee, after consulting with management, establishes the corporate performance objectives for our company and makes decisions with
respect to any base salary adjustment, approves certain individual performance objectives and target annual cash bonus opportunities and formulates recommendations with respect to equity awards for
our executive officers, including the Named Executive Officers, for the upcoming year. Any recommendations for equity awards to our executive officers are submitted to our board of directors for its
consideration and approval. After the end of the fiscal year, the compensation committee reviews the performance of our </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
compensation committee reviews on a periodic basis, at least annually, our executive compensation program, including any incentive compensation plans, to determine whether they are
appropriate, properly coordinated, and achieve their intended purposes and recommends to our board of directors any modifications or new plans or arrangements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Role of Management  </I></FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In carrying out its responsibilities, the compensation committee works with members of our management, including our CEO. Typically,
our management assists the compensation committee by providing information on corporate and individual performance, market data, and management's perspective and recommendations on compensation
matters. This information has included an analysis of the compensation mix and levels of our executive officers compared to the competitive market (as determined using compensation survey data)
prepared by our Human Resources Department. The compensation committee then uses this information as reference points in its deliberations on specific compensation actions and decisions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically,
the initial compensation arrangements with our executive officers, including the Named Executive Officers, have been determined in negotiations with each individual
executive. Our CEO has been responsible for negotiating these arrangements, with the oversight and final approval of the compensation committee (except for Mr.&nbsp;Cooper's initial compensation
arrangement, which was negotiated and approved by the compensation committee). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Typically,
our CEO will make recommendations to the compensation committee regarding compensation matters, including the compensation of our executive officers (except with respect to
his own compensation). Historically, these recommendations have been based on a review of competitive market data as prepared by our Human Resources Department and his evaluation of each executive
officer's individual performance. He also attends compensation committee meetings, except with respect to discussions involving his own compensation. Further, he recuses himself from meetings of our
board of directors when they engage in deliberations with respect to his equity compensation awards. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;While
the compensation committee solicits and reviews our CEO's recommendations and proposals with respect to compensation-related matters, the compensation committee only uses these
recommendations and proposals as one factor in making compensation decisions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Role of Compensation Consultant  </I></FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The compensation committee is authorized to retain the services of one or more executive compensation advisors from time to time, as it
sees fit, in connection with carrying out its duties. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Beginning
in 2010, the compensation committee engaged Compensia,&nbsp;Inc., a national compensation consulting firm that provides executive compensation advisory services, to assist it
in administering our executive compensation program. In addition, as we have begun the transition to public company status, Compensia has assisted the compensation committee in evaluating various
alternatives for our equity compensation strategies and funding, and various other aspects of our executive compensation program. In the future, we expect that the compensation committee, as part of
its annual review of our executive officers' compensation, will instruct its executive compensation advisor to perform an analysis of our executive compensation program to ensure alignment with our
compensation strategy and competitive market practices. Compensia serves at the discretion of the compensation committee. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To assess the competitiveness of our executive compensation program and current compensation levels and to assist it in setting
compensation levels, historically the compensation committee referred to standard industry surveys, including the Radford High-Technology Executive Compensation Survey. While the
compensation committee reviewed this compensation data to inform its decision-making process, it did not set compensation components to meet specific benchmarks. Instead, the compensation committee
used this data as a point of reference so that it could set total compensation levels that it believed were reasonably competitive. While compensation levels differed among our executive officers
based on competitive factors, and the role, responsibilities, and performance of each specific executive officer, there were not material differences in the compensation policies and practices for our
executive officers, including the Named Executive Officers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
2011, the compensation committee, assisted by our management and Compensia, began to develop a compensation peer group comprised of comparably-sized publicly-held
companies, taking into consideration size and growth potential, to be used as a reference source in connection with future executive compensation deliberations. This compensation peer group, which
consisted of both technology companies that had conducted an initial public offering of their equity securities within the past several years and similarly-sized companies in the same industry sector,
was used by the compensation committee for reference purposes during its compensation deliberations during 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
peer group is comprised of the following companies: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Base salary is the primary fixed component of our executive compensation program. We use base salary to compensate our executive
officers, including the Named Executive Officers, for services rendered during the year, and to ensure that we remain competitive in attracting and retaining executive talent. The compensation
committee conducts an annual review of each
executive officer's base salary and makes adjustments as it determines to be reasonable and necessary to reflect the scope of an executive officer's performance, contributions, responsibilities,
experience, prior salary level and position (in the case of a promotion), and market conditions. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
February 2010, the compensation committee reviewed the base salaries of our executive officers, including the Named Executive Officers, taking into consideration a compensation
analysis performed </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>by
our Human Resources Department and the base salary recommendations of our CEO (except with respect to his own base salary), as well as the other factors described above. Exercising its judgment and
discretion, the compensation committee determined to make adjustments to the annual base salaries of certain of our executive officers that ranged from 0% to 28%. The compensation committee did not
benchmark the base salaries of our executive officers against any specific companies or compensation surveys, but did take into account data from the Radford High-Technology Executive
Compensation Survey and data from Compensia in making these subjective determinations. The compensation committee determined that such adjustments were necessary and appropriate to maintain the fixed
component of our executive officers' compensation at competitive levels. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
adjustments to the base salaries of the Named Executive Officers for 2010 were as follows: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We use cash bonuses to motivate our executive officers, including the Named Executive Officers, to achieve our annual financial and
operational objectives, while making progress towards our longer-term growth and other goals. Generally, the compensation committee pays bonuses to our executive officers in its discretion
after the end of the year based on its evaluation of the achievement of one or more corporate performance measures established in our annual operating plan and individual performance requirements, as
described further below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the beginning of each year, the compensation committee adopts an annual bonus plan for our management team and selects one or more corporate financial and operational measures for use
in determining the target size of the bonus pool for the year from which bonuses will be paid. In addition, with respect to our executive officers, including the Named Executive Officers, the
compensation committee also establishes target bonus opportunities for each executive officer and determines the individual performance objectives for variable compensation for certain executive
officers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
February 2010, the compensation committee approved our Executive Bonus Plan for purposes of providing bonus opportunities to our management team, including the Named Executive

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
compensation committee believed that the target levels for these two performance measures for 2010 would require a focused effort by management to generate the target funding for the
bonus pool associated with these measures. The Executive Bonus Plan provided that the bonus pool would receive minimum funding at 50% of the target funding level established for the annual bookings
measure if we achieved at least 90% of our annual bookings target for the year (on a weighted value basis, this amount would represent 37.5% of the potential funding of the bonus pool). Between 90%
and 100% achievement of our annual bookings target for the year, the funding of the bonus pool would increase by 5% for each 1% of performance. Finally, above our annual bookings target for the year,
the funding of the bonus pool would increase by 25% for each 2.5% of performance up to a maximum funding of 250% if we achieved 115% of our annual bookings target. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Executive Bonus Plan also provided that, in the event that we achieved 90% of our annual bookings target for the year, the bonus pool would receive funding of an additional 25% of
the target funding level for the overall bonus pool if we achieved our free cash flow target for the year. A failure to achieve this target level would result in no funding of the bonus pool with
respect to this measure. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Individual Performance Measures  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the Executive Bonus Plan, if we achieved minimum funding of the bonus pool, our CEO was to formulate recommendations on the
amount payable to each executive officer, subject to the approval of the compensation committee. If we achieved at least 90% of our annual bookings target for the year, then the amounts payable would
be based on each participant's actual performance as measured against one or more individual performance objectives. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To
achieve our compensation objective of rewarding individual performance, our CEO developed a series of performance objectives for our executive officers, including the other Named
Executive Officers (other than himself), which he deemed to be integral to the achievement of the corporate performance objectives as well as the strengthening of our internal operations. In addition,
the compensation committee determined the individual performance objectives that would be applicable to our CEO. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For
purposes of the Executive Bonus Plan, these performance objectives for the Named Executive Officers participating in the Executive Bonus Plan were as follows: for Mr.&nbsp;Steele,
his performance objectives related to achieving quarterly revenue goals of $67&nbsp;million in the aggregate over four quarters, IPO preparedness, obtaining additional cloud-based business, margin
improvements and sales team productivity; for Mr.&nbsp;Auvil, his performance objectives related to timely audit, system integration, implementing internal controls and process initiatives,
continued cost reductions, quarterly cash balance objectives and continuing to improve the forecasting and reporting process; and for Mr.&nbsp;Chambers, his performance objectives related to product
development milestones, cost efficiency and employee attrition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Further,
our CEO was to evaluate each executive officer's individual contributions towards the achievement of these performance objectives. In the case of our CEO, the compensation
committee would evaluate his individual contributions towards the achievement of his performance objectives. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Award Decisions and Analysis  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In February 2011, the compensation committee evaluated our performance during 2010 and determined the amount of the annual cash bonuses
to be paid to our executive officers, including the Named Executive Officers, for 2010. In making these awards, the compensation committee consulted with our CEO with respect to the Named Executive
Officers (except with respect to his own bonus) and evaluated our financial and operational performance and the level of achievement of the corporate performance objectives for the year. The
compensation committee determined that, with respect to the annual bookings measure, we had achieved 96% of our
annual bookings target for the year, and with respect to the free cash flow measure, had exceeded our cash flow target for the same period. Based on these results, the compensation committee then set
the size of the bonus pool to be used to pay cash bonuses under the Executive Bonus Plan at 85% of the target. Therefore, target bonus based on achievement of corporate objectives would be 85% of the
amount of each Named Executive Officers' target bonus. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
CEO evaluated the achievement of each executive officer against his individual performance objectives and formulated a recommendation for each such executive officer's annual bonus
for consideration by the compensation committee. These recommendations were based on his subjective assessment of each individual's contributions against the personal performance objectives during the
year. In the case of our CEO, the compensation committee evaluated his performance against his individual performance objectives and determined the amount of his annual bonus. Mr.&nbsp;Steele was
determined to have satisfied his performance objectives at a level of 95%. Mr.&nbsp;Auvil was determined to have satisfied his personal performance objectives at a level of 98%. Mr.&nbsp;Chambers
was determined to have satisfied his personal performance objectives at a level of 90%. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As our Senior Vice President, Worldwide Sales, Mr.&nbsp;Hickman-Smith was eligible for a commission plan providing for the
opportunity to receive incentive compensation based on the ability of our sales organization to achieve specified pre-established sales quotas throughout the year. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For
2010, his target incentive compensation opportunity was equal to 100% of his annual base salary, $225,000. The majority of this target incentive compensation opportunity ($200,000)
was based on the sales organization's actual performance during the year as measured against our monthly, quarterly, and annual bookings quotas for new business, renewals and professional services.
The amounts earned under this portion of his incentive compensation opportunity were to be paid one month in arrears following our determination of the actual bookings for each month. In addition, a
portion of this target annual incentive compensation opportunity ($25,000) was achievable if 50% or more of the representatives in the sales organization achieved 100% of their bookings quotas for the
year. The amounts paid under this incentive award opportunity are paid on an annual basis. In addition to his target incentive compensation, Mr.&nbsp;Hickman-Smith was eligible to receive an annual
revenue bonus of
$25,000, payable upon meeting the specified revenue targets for the first half and second half of the year. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have not disclosed the specific target levels for sales commission quotas because we believe that such disclosure would result in competitive harm to our company. The specific target
levels were based on our historical operating results and growth rates, as well as our expected future results, and were designed to require significant effort on the part of Mr.&nbsp;Hickman-Smith. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mr.&nbsp;Hickman-Smith
earned sales commissions of $182,873 during 2010. Mr.&nbsp;Hickman-Smith did not receive the bonus associated with the sales force productivity. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We use equity awards to incentivize and reward our executives officers, including the Named Executive Officers, for
long-term corporate performance based on the value of our common stock and, thereby, to align the interests of our executive officers with those of our stockholders. These equity awards
have been granted in the form of stock options to purchase shares of our common stock. We believe that stock options, when granted with exercise prices equal to the fair market value of our common
stock on the date of grant, provide an appropriate long-term incentive for our executive officers, since the stock options reward them only to the extent that our stock price grows and
stockholders realize value following their grant date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Typically,
we have granted stock options to our executive officers, including the Named Executive Officers, as part of the compensation committee's annual review of executive

compensation committee has not applied a rigid formula in determining the size of these equity awards. Instead, the compensation committee formulates an equity award recommendation for each
executive officer after taking into consideration a compensation analysis performed by our Human Resources Department, the equity award recommendations of our CEO (except with respect to his own
award), the scope of an executive officer's performance, contributions, responsibilities and experience, and the amount of equity compensation held by the executive officer (including the current
economic value of his unvested equity and the ability of these unvested holdings to satisfy our retention objectives, market conditions, and internal equity). These recommendations are then submitted
to our
board of directors for approval. In making its award decisions, our board of directors exercises its judgment and discretion to set the size of each award at a level it considers appropriate to create
a meaningful opportunity for reward predicated on the creation of long-term stockholder value. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;11, 2010, the compensation committee approved recommendations for stock option grants for each of our executive officers, including the Named Executive Officers, in
recognition of our financial results and each executive officer's individual performance for 2009. These recommendations then were submitted to our board of directors for review and consideration. On
March&nbsp;9, 2010, our board of directors approved stock option grants for each of our executive officers, including the Named Executive Officers. In the case of our CEO, the independent members of
our board of directors approved his stock option grant. The size of these stock option grants was determined by the compensation committee based on its evaluation of the compensation analysis prepared
by our Human Resources Department, its subjective assessment of the performance of each of our executive officers, and its motivation and retention objectives for each of our executive officers. These
stock options were granted with an exercise price equal to $1.94 per share, the fair market value of our common stock as determined by our board of directors on that date. The stock option grants made
to the Named Executive Officers were as follows: </FONT></P>

we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites to our
executive officers, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and
effective, and for recruitment and retention purposes.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

offer letter, the Proprietary Information and Inventions Agreement, and the Arbitration Agreement. Our employment agreement with Mr.&nbsp;Steele is comprised solely of an offer letter and the
Employee Confidentiality Agreement. The initial terms and conditions of employment of each of the Named Executive Officers are set forth in a written employment offer letter with such individual. Each
of these arrangements was approved on our behalf by our board of directors or, in certain instances, the compensation committee. We believe that these employment offer letters were necessary to induce
these individuals to forego other employment opportunities or leave their current employer for the uncertainty of a demanding position in a new and unfamiliar organization. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
filling these executive positions, our board of directors and the compensation committee, as applicable, was aware that it would be necessary to recruit candidates with the requisite
experience and skills to manage a growing business in a unique market niche. Accordingly, it recognized that it would need to develop competitive compensation packages to attract qualified candidates
in a dynamic labor market. At the same time, our board of directors and the compensation committee was sensitive to the need to integrate new executive officers into the executive compensation
structure that it was seeking to develop, balancing both competitive and internal equity considerations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Each
of these employment offer letters provided for "at will" employment and sets forth the initial compensation arrangements for the executive officer, including an initial base salary,
an annual cash bonus opportunity and/or a commissions plan, and an equity award in the form of a stock option to purchase shares of our common stock. Certain of the employment offer letters contain
certain qualifying termination and change in control benefits in favor of certain Named Executive Officers. These arrangements provide for payments and benefits upon termination of their employment in
specified circumstances, including following a change in control. These arrangements (including potential payments and terms) are discussed in more detail in "&#151;Offer Letters and

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;162(m) of the Internal Revenue Code generally disallows public companies a tax deduction for federal income tax purposes
of remuneration in excess of $1&nbsp;million paid to the chief executive officer and each of the three other most highly-compensated executive officers (other than the chief financial officer) in
any taxable year. Generally, remuneration in excess of $1&nbsp;million may only be deducted if it is "performance-based compensation" within the meaning of the Code. In this regard, the compensation
income realized upon the exercise of stock options granted under a stockholder-approved stock option plan generally will be deductible so long as the options are granted by a committee whose members
are non-employee directors and certain other conditions are satisfied. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
we are not currently publicly-traded, our board of directors has not previously taken the deductibility limit imposed by Section&nbsp;162(m) into consideration in setting
compensation for our executive officers. We expect that, where reasonably practicable, the compensation committee will seek to qualify the variable compensation paid to our executive officers for the

our company of providing such compensation, including the potential impact of Section&nbsp;162(m). In the future, the compensation committee may, in its judgment, authorize compensation payments

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sections&nbsp;280G and 4999 of the Internal Revenue Code provide that executive officers and directors who hold significant equity
interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of our company that exceeds
certain prescribed limits, and that our company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We did not provide any executive officer, including any Named
Executive Officer, with a "gross-up" or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections&nbsp;280G or
4999 during 2010, and we have not agreed and are not otherwise obligated to provide any executive officer with such a "gross-up" or other reimbursement. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We follow ASC 718 for our stock-based compensation awards. ASC 718 requires companies to measure the compensation expense for all
share-based payment awards made to employees and directors, including stock options, based on the grant date "fair value" of these awards. This calculation is performed for accounting purposes and
reported in the compensation tables below, even though our executive officers may never realize any value from their awards. ASC 718 also requires companies to recognize the compensation cost of their
stock-based compensation awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our stock option agreements for each of our Named Executive Officers generally provide for acceleration of vesting of 100% of the
unvested shares underlying their options in the event of an involuntary termination (as such term is defined in the stock option agreement) within 18&nbsp;months following a change in control in our
company for employees who have worked for our company for one year or more prior to the involuntary termination. In the case of an involuntary termination (as such term is defined in
Mr.&nbsp;Cooper's stock option agreement), Mr.&nbsp;Cooper's options would accelerate as provided for under "&#151;Offer Letters and Arrangements" and "&#151;Grants of Plan-Based
Awards." The following table summarizes the value of this
acceleration to these Named Executive Officers pursuant to these awards, assuming an involuntary termination and change in control as of December&nbsp;31, 2010. Values are based upon the value of a
share of our common stock as of December&nbsp;31, 2010, which we assumed to be the midpoint of the price range set forth on the cover page of this prospectus, minus the exercise price. </FONT></P>

under Section&nbsp;422 of the Code, and nonstatutory stock options, as well as for the issuance of shares of restricted stock. We may grant incentive stock options only to our employees. We may

The exercise price of incentive stock options granted to 10% stockholders must be at least equal to 110% of the fair market value of our common stock on the date of grant. The maximum permitted
term of options granted under our 2002 Stock Option/Stock Issuance Plan is ten years. In the event of a "change in control," as defined in the 2002 Stock Option/Stock Issuance Plan, the 2002 Stock
Option/Stock Issuance Plan provides that, unless the applicable option agreement provides otherwise, options held by current employees, directors and consultants will terminate if not assumed or
substituted with no acceleration of vesting. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of September&nbsp;30, 2011, we had reserved 28,555,342 shares of our common stock for issuance under our 2002 Stock Option/Stock Issuance Plan. As of September&nbsp;30, 2011,
options to purchase 7,088,122 of these shares had been exercised, options to purchase 20,227,426 of these shares remained outstanding and 1,557,769 of these shares remained available for future grant.
The options outstanding as of September&nbsp;30, 2011 had a weighted-average exercise price of $1.73. Our 2012 Equity Incentive Plan will be effective upon the date of this prospectus. As a result,
we will not grant any additional options under the 2002 Stock Option/Stock Issuance Plan following that date and the 2002 Stock Option/Stock Issuance Plan will terminate at that time. However, any
outstanding options granted under the 2002 Stock Option/Stock Issuance Plan will remain outstanding, subject to the terms of our 2002 Stock Option/Stock Issuance Plan and stock option agreements,
until such outstanding options are exercised or until they terminate or expire by their terms. Options granted under the 2002 Stock Option/Stock Issuance Plan generally have terms similar to those
described below with respect to options granted under our 2012 Equity Incentive Plan, except that stock option agreements evidencing options granted to employees under our 2002 Stock Option/Stock
Issuance Plan generally provide for partial acceleration of vesting in connection with a change in control followed by the optionee's involuntary termination. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
2012 Equity Incentive Plan will be administered by our compensation committee, all of the members of which are non-employee directors under applicable federal securities
laws and outside directors as defined under applicable federal tax laws, or by our board of directors acting in place of our compensation committee. The compensation committee will have the authority
to construe and interpret our 2012 Equity Incentive Plan, grant awards and make all other determinations necessary or advisable for the administration of the plan. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
anticipate that our 2012 Equity Incentive Plan will provide for the grant of incentive stock options that qualify under Section&nbsp;422 of the Code only to our employees. No more
than&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares may be issued under the 2012 Equity Incentive Plan as incentive stock options. All awards other than incentive stock options may be granted to our employees, directors,

consultants, independent contractors and advisors, provided the consultants, independent contractors and advisors render services not in connection with the offer and sale of securities in a
capital-raising transaction. The exercise price of stock options must be at least equal to the fair market value of our common stock on the date of grant. The exercise price of incentive stock options
granted to 10% stockholders must be at least equal to 110% of that value. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
general, options will vest over a four-year period. Options may vest based on time or achievement of performance conditions. Our compensation committee may provide for
options to be exercised only as they vest or to be immediately exercisable with any shares issued on exercise being subject to our right of repurchase that lapses as the shares vest. The maximum term
of options granted under our 2012 Equity Incentive Plan is ten years, except that incentive stock options granted to 10% stockholders will have a maximum term of five years. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
restricted stock award is an offer by us to sell shares of our common stock subject to restrictions. A restricted stock award may vest based on time or achievement of performance
conditions. The price (if any) of a restricted stock award will be determined by the compensation committee. Unless otherwise determined by the compensation committee at the time of award, vesting
will cease on the date the participant no longer provides services to us and unvested shares will be forfeited to us. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Stock
appreciation rights provide for a payment, or payments, in cash or shares of our common stock, to the holder based upon the difference between the fair market value of our common
stock on the date of exercise and the stated exercise price up to a maximum amount of cash or number of shares. Stock appreciation rights may vest based on time or achievement of performance
conditions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Restricted
stock units represent the right to receive shares of our common stock at a specified date in the future, subject to forfeiture of that right because of termination of
employment or failure to achieve certain performance conditions. If a restricted stock unit has not been forfeited, then on the date specified in the restricted stock unit agreement, we will deliver
to the holder of the restricted stock unit whole shares of our common stock (which may be subject to additional restrictions), cash or a combination of our common stock and cash. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Performance

lifetime of the optionee only by the optionee or the optionee's guardian or legal representative. Options granted under our 2012 Equity Incentive Plan generally may be exercised for a period of three
months after the termination of the optionee's service to us, or for a period of 12&nbsp;months in cases of death or disability, or such longer period as our compensation committee may provide.

transactions, our compensation committee may accelerate the vesting of awards (a)&nbsp;immediately upon the occurrence of the transaction, whether or not the award is continued, assumed or

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We

the most recent increase in the number of shares of our common stock available under the plan which was approved by our stockholders, unless it is terminated earlier by our board of directors. Our
board of directors may amend or terminate our 2012 Equity Incentive Plan at any time. If our board of directors amends our 2012 Equity Incentive Plan, it does not need to ask for stockholder approval
of the amendment unless required by applicable law. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We anticipate that we will adopt a 2012 Employee Stock Purchase Plan that will become effective on the date of this prospectus which
will be a plan designed to enable eligible employees to purchase shares of our common stock periodically at a discount following the date of this prospectus. Purchases will be accomplished through
participation in discrete purchase periods. Our 2012 Employee Stock Purchase Plan will be intended to qualify as an employee stock purchase plan under Section&nbsp;423 of the Code. We anticipate we
will initially reserve&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares of our common stock for issuance under our 2012 Employee Stock Purchase Plan. We anticipate that the number of shares reserved for issuance under our
2012
Employee Stock Purchase Plan will increase automatically on the first day of January of each of 2013 through 2019 by the number of shares equal to&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of the total outstanding
shares of
our common stock as of the immediately preceding December&nbsp;31st&nbsp;(rounded to the nearest whole share), but not more than&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares of our common stock. However, our board of

compensation committee will administer our 2012 Employee Stock Purchase Plan. Our employees generally are eligible to participate in our 2012 Employee Stock Purchase Plan if they are
employed by us for at least 20&nbsp;hours per week and more than five months in a calendar year. Employees who are 5% stockholders, or would become 5% stockholders as a result of their participation
in our 2012 Employee Stock Purchase Plan, are ineligible to participate in our 2012 Employee Stock Purchase Plan. We may impose additional restrictions on eligibility. Under our 2012 Employee Stock
Purchase Plan, eligible employees are able to acquire shares of our common stock by accumulating funds through payroll deductions. Our eligible employees will be able to select a rate of payroll
deduction between 1% and 15% of their cash compensation. We will also have the right to amend or terminate our 2012 Employee Stock Purchase Plan, except that, subject to certain exceptions, no such
action may adversely affect any outstanding rights to purchase stock under the plan. Our 2012 Employee Stock Purchase Plan will terminate on the tenth anniversary of the last day of the first purchase
period, unless it is terminated earlier by our board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When
an initial purchase period commences, our employees who meet the eligibility requirements for participation in that purchase period will automatically be granted a nontransferable
option to purchase shares in that purchase period. For subsequent purchase periods, new participants will be required to enroll in a timely manner. Once an employee is enrolled, participation will be
automatic in subsequent purchase periods. Each purchase period will run for no more than six months. An employee's participation automatically ends upon termination of employment for any reason. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except
for the first purchase period, each purchase period will be for six months (commencing each February and August). The first purchase period will begin upon the effective date of
this offering and will end on&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;, 2012. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;No
participant will have the right to purchase more than 3,000 shares of our common stock in any purchase period, or such smaller number of shares as our compensation committee shall
approve. No participant will have the right to purchase our shares in an amount, when aggregated with purchase rights under all our employee stock purchase plans that are also in effect in the same
calendar year(s), that has a fair market value of more than&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;, determined as of the first day of the applicable purchase period, for each calendar year in which that right is
outstanding. The purchase price for shares of our common stock purchased under our 2012 Employee Stock Purchase Plan will be 85% of the lesser of the fair market value of our common stock on
(i)&nbsp;the first trading day of the purchase period and (ii)&nbsp;the last trading day of that purchase period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
we experience a change in control transaction, the purchase period that commenced prior to the closing of the proposed change in control transaction will be shortened and terminated
on a new purchase date. The new purchase date will occur prior to the closing of the proposed change in control
transaction and our 2012 Employee Stock Purchase Plan will then terminate on the closing of the proposed change in control. </FONT></P>

of fiduciary duties as directors, except for liability: </FONT></P>

amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that
amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our
directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
restated bylaws provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or
proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise. Our restated bylaws provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any
action, suit or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was serving at our request as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. Our restated bylaws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final
disposition of any action or proceeding, subject to very limited exceptions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior
to the closing of this offering, we intend to enter into indemnification agreements with each of our directors and executive officers that may be broader than the specific
indemnification provisions contained in our restated certificate of incorporation and bylaws. These indemnification agreements may require us, among other things, to indemnify our directors and
executive officers against liabilities that may arise by reason of their status as a director, officer or employee or their service to our company. These indemnification agreements may also require us
to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit or proceeding. We believe that these agreements are necessary to attract
and retain qualified individuals to serve as directors and executive officers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In January 2009, our board of directors determined that certain stock options granted to our employees, including our executive
officers, were no longer providing the incentive intended when they were originally granted and the holders of all outstanding, unexercised options, whether vested or unvested, that had exercise
prices per share equal to $2.28 or higher were offered an opportunity to cancel such options in exchange for a new option with an exercise price per share equal to the then current fair market value
per share. In exchange for the lower exercise price per share the new stock options were treated for vesting purposes as if they were granted on the date of the exchange, whether such options were
previously vested or not. The new exercise price per share and revised vesting schedule was designed to incentivize our employees, including our executive officers, to work towards achieving our
long-term financial goals. Two of our executive officers, Mr.&nbsp;Steele and Mr.&nbsp;Hickman-Smith, participated in the stock option exchange. Mr.&nbsp;Steele and
Mr.&nbsp;Hickman-Smith exchanged options convertible into a total of 503,527 and 562,304 shares of our common stock, respectively. </FONT></P>

of approximately 40,541,990 shares of our common stock will be entitled to rights with respect to the registration of these shares under the Securities Act, as described below. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The holders of at least 50% of the then-outstanding shares having registration rights may make a written request to us for
the registration of the offer and sale of all or part of the shares having registration rights or registrable securities. The holders of at least 25% of the then-outstanding shares may
make the same request at any time after six months after the effective date of our first registration statement, if the amount of registrable securities to be registered has an aggregate market value
of at least $10.0&nbsp;million. We are only required to file two registration statements that are declared effective upon exercise of these demand registration rights. We may postpone the filing of
a registration statement for up to 90&nbsp;days in a 12-month period if our board of directors determines that the filing would be seriously detrimental to us and our stockholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If we register any of our securities for public sale, holders of shares having registration rights will have the right to include their
shares in the registration statement. However, this right does not apply to a registration relating to sales of shares of participants in one of our stock plans or a registration relating to a
corporate reorganization. The underwriters of any underwritten offering will have the right to limit the number of shares registered by these holders if
they determine in good faith that marketing factors require limitation, in which case the number of shares to be registered will be apportioned pro rata among these holders, according to the total
amount of securities entitled to be included by each holder, or in a manner mutually agreed upon by the holders. However, the number of shares to be registered by these holders cannot be reduced below
25% of the total shares covered by the registration statement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Anti-Takeover Provisions  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws, as we expect they will be in effect
upon the completion of this offering, could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below,
may have the effect of discouraging takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe
that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because
negotiation of these proposals could result in an improvement of their terms. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are subject to the provisions of Section&nbsp;203 of the Delaware General Corporation Law regulating corporate takeovers. In

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generally,
a business combination includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder
is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation's outstanding
voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate
that Section&nbsp;203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our restated certificate of incorporation and our restated bylaws, as we expect they will be in effect upon the completion of this
offering, include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following: </FONT></P>

<UL>
<DL compact>
<DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2><I>Board of Directors Vacancies.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;Our restated certificate of
incorporation and restated bylaws will authorize only our board of directors to fill vacant directorships, including newly created seats. In addition, the number of directors constituting our board of
directors is permitted to be set only by a resolution adopted by a majority vote of our entire board of directors. These provisions would prevent a stockholder from increasing the size of our board of
directors and then gaining control of our board of directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our board of directors
but promotes continuity of management.  </FONT> <FONT SIZE=2>

incorporation and restated bylaws will provide that our board is classified into three classes of directors, each with staggered three year terms. A third party may be discouraged from making a tender
offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors. See
"Management&#151;Board of Directors Composition."  </FONT> <FONT SIZE=2>
<BR><BR></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2><I>Stockholder Action; Special Meetings of Stockholders.</I></FONT><FONT SIZE=2>&nbsp;&nbsp;Our
restated certificate of incorporation will provide that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a
result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our
amended and restated bylaws. Our restated bylaws further will provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairman of our board of
directors, our Chief Executive Officer or our President, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force
consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.  </FONT> <FONT SIZE=2>

meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our restated bylaws also will specify certain requirements regarding the form and
content of a stockholder's notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our
annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also discourage or deter a potential acquirer </FONT></DD></DL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior to this offering, there has been no public market for our common stock, and we cannot predict the effect, if any, that market
sales of shares of our common stock or the availability of shares of our common stock for sale will have on the market price of our common stock prevailing from time to time. Nevertheless, sales of
substantial amounts of our common stock, including shares issued upon exercise of outstanding options, in the public market following this offering could adversely affect market prices prevailing from
time to time and could impair our ability to raise capital through the sale of our equity securities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon
the closing of this offering, we will have a total of&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares of our common stock outstanding, based on the
47,402,137 shares of our capital stock outstanding as of
September&nbsp;30, 2011. Of these outstanding shares, all of the&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares of common stock sold in this
offering will be freely tradable, except that any shares purchased in this
offering by our affiliates, as that term is defined in Rule&nbsp;144 under the Securities Act, would only be able to be sold in compliance with the Rule&nbsp;144 limitations described below. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
remaining outstanding shares of our common stock will be deemed "restricted securities" as defined in Rule&nbsp;144. Restricted securities may be sold in the public market only if
they are registered under the Securities Act or if they qualify for an exemption from registration under Rule&nbsp;144 or Rule&nbsp;701 promulgated under the Securities Act, which rules are
summarized below. In addition, all of our security holders have entered into market standoff agreements with us or lock-up agreements with the underwriters under which they have agreed,
subject to specific exceptions, not to sell any of our stock for at least 180&nbsp;days following the date of this prospectus, as described below. As a result of these agreements and the provisions

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following is a summary of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of our
common stock to non-U.S. holders (defined below), who purchase our common stock pursuant to this offering and hold our stock as a capital asset (generally, on asset hold for investment
purposes), but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively,
so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service (the "IRS") with respect to the statements
made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions. </FONT></P>

you are an individual, you may, in many cases, be deemed to be a resident alien, as opposed to a nonresident alien, by virtue of being present in the United States for at least
31&nbsp;days in the calendar year and for an aggregate of at least 183&nbsp;days during a three-year period ending in the current calendar year. For these purposes, all the days
present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year are counted.
Resident aliens are subject to U.S. federal income tax as if they were U.S. citizens. Such an individual is urged to consult his or her own tax advisor regarding U.S. federal income tax consequences
of the ownership of our common stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Distributions  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have not made any distributions on our common stock, and we do not plan to make any distributions for the foreseeable future.
However, if we do make distributions on our common stock, those payments will constitute dividends for U.S. tax purposes to the extent paid from our current or accumulated earnings and profits, as
determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and
will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an
applicable income tax treaty. Generally, in order for us or our paying agent to withhold tax at a lower treaty rate, a non-U.S. holder must certify its entitlement to treaty benefits. A
non-U.S. holder generally can meet this certification requirement by providing a Form&nbsp;W-8BEN (or any successor form) or appropriate substitute form to us or our paying
agent. If the holder holds the stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to the agent. The
holder's agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. For payments made to a foreign partnership or other
pass-through entity, the certification requirements generally apply to the partners </FONT></P>

received by you that are effectively connected with your conduct of a U.S. trade or business and, if required by an applicable income tax treaty, attributed to a permanent
establishment in the United States, are exempt from such withholding tax. In order to obtain this exemption, you must provide us with an applicable IRS form&nbsp;W-8 (generally
Form&nbsp;W-8ECI) properly certifying such exemption. Such effectively connected dividends, although not subject to withholding tax, are taxed at the same graduated rates applicable to
U.S. persons, net of certain deductions and credits and subject to an applicable income tax treaty providing otherwise. In addition, if you are a corporate non-U.S. holder, dividends that
you receive that are effectively connected with your conduct of a U.S. trade or business, subject to certain adjustments, may also be subject to a branch profits tax at a rate of 30% or such lower
rate as may be specified by an applicable income tax treaty. </FONT></P>

holding corporation" for U.S. federal income tax purposes (a "USRPHC"), at any time within the shorter of the five-year period preceding the disposition or your holding period for our
common stock. </FONT></DD></DL>
</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
believe that we are not currently and will not become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real
property relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our
common stock is regularly traded on an established securities market, such common stock will be treated as a U.S. real property interest only if you actually or constructively hold more than 5% of
such regularly traded common stock at any time during the applicable period that is specified in the Code. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
you are a non-U.S. holder described in the first bullet above, you will generally be required to pay tax on the net gain derived from the sale under regular graduated U.S.
federal income tax rates, and corporate non-U.S. holders described in the first bullet above may be subject to the additional branch profits tax at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be required to pay a flat 30% tax on the gain derived
from the sale, which tax may be offset by U.S. source capital losses (even though you are not considered a resident of the United States). You should consult any applicable income tax or other
treaties that may provide for different rules. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Backup Withholding and Information Reporting  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax
withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of
residence. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Payments
of dividends or of proceeds on the disposition of stock made to you may be subject to additional information reporting and backup withholding (currently at a rate of 28%) unless
you either (i)&nbsp;provide a correct taxpayer identification number and certify that you are not subject to backup withholding on Form&nbsp;W-9, or (ii)&nbsp;establish an exemption,
for example by properly certifying your non-U.S. status on a Form&nbsp;W-8BEN or another appropriate version of IRS Form&nbsp;W-8. Notwithstanding the
foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person and you have not provided a
correct taxpayer identification number, or if we or our paying agent has received notice from the IRS that backup withholding is required. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Backup
withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund or credit generally may be obtained, provided that the required information is furnished to the IRS in a timely manner. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Recent Legislative Developments  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Recent legislation may begin imposing withholding at a rate of 30% on payments to certain foreign entities (including financial
institutions, as specifically defined in this new legislation and certain other non-U.S. entities) of dividends on, and the gross proceeds of dispositions of, U.S. common stock, unless
(i)&nbsp;the foreign financial institution undertakes certain diligence and reporting obligations or (ii)&nbsp;the foreign non-financial entity either certifies it does not have any
substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner. If the payee is a foreign financial institution, it must enter into an agreement with the U.S.
Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and
withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. The withholding requirements are generally scheduled to
phase-in beginning on January&nbsp;1, 2014. You should consult your tax advisor regarding the possible implications of this legislation on your investment in our common stock. </FONT></P>

covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created
if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. </FONT> <FONT SIZE=2>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, convertible preferred stock and stockholders' deficit and cash flows
present fairly, in all material respects, the financial position of Proofpoint,&nbsp;Inc. and its subsidiaries (the "Company") at December&nbsp;31, 2010 and 2009, and the results of their
operations and their cash flows for each of the three years in the period ended December&nbsp;31, 2010 in conformity with accounting principles generally accepted in the United States of America.
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of
these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> 1. The Company and Summary of Significant Accounting Policies  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> The Company  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proofpoint,&nbsp;Inc. (the "Company") was incorporated in Delaware in June 2002 and is headquartered in California. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proofpoint
is a pioneering security-as-a-service vendor that enables large and mid-sized organizations worldwide to defend, protect,
archive and govern their most sensitive data. The Company's security-as-a-service platform is comprised of a number of data protection solutions, including threat
protection, regulatory compliance, archiving and governance, and secure communication. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Liquidity  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has relied principally on preferred stock financings to fund its operating activities to date and at September&nbsp;30,
2011, the Company had an accumulated deficit of $155,694. During the years ended December&nbsp;31, 2008, 2009 and 2010, and the nine months ended September&nbsp;30, 2011 the Company incurred a net
loss of $25,888, $19,738, $20,865 and $13,717 (unaudited), respectively, and had negative cash flows from operations of $7,555 and $3,707, positive
cash flows from operations of $3,409 and negative cash flows from operations of $329 (unaudited), respectively. Management plans to improve operating results by growing revenue while controlling
costs. Management believes that its plans provide sufficient liquidity for the Company to finance its operations for at least the next 12&nbsp;months from December&nbsp;31, 2010. There is no
assurance, however, that management will be successful with its plans or otherwise achieve its intended business objectives and that financing alternatives, if needed, will be available on terms
acceptable to the Company, or at all. Failure to generate sufficient cash from operations, raise additional capital or control operating costs may require the Company to modify, delay or abandon
planned expenditures and could have an impact on the Company's ability to achieve intended business objectives. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Principles of Consolidation  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All
intercompany transactions and balances have been eliminated in consolidation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Foreign Currency Remeasurement and Transactions  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company's sales to international customers are generally U.S. dollar-denominated. As a result, there are no significant foreign
currency gains or losses related to these transactions. The functional currency for the Company's wholly-owned foreign subsidiaries is the U.S. dollar. Accordingly, the subsidiaries
remeasure monetary assets and liabilities at period-end exchange rates, while nonmonetary items are remeasured at historical rates. Income and expense accounts are remeasured at the
average exchange rates in effect during the year. Remeasurement adjustments are recognized in the consolidated statement of operations as transaction gains or losses within other income (expense),
net, in the period of occurrence. Aggregate transaction losses included in determining net loss was $166, $177 and $187 for the years ended December&nbsp;31, 2008, 2009 and 2010, respectively and a
net loss of $58 (unaudited) and a net gain of $93 (unaudited) for the nine months ended September&nbsp;30, 2010 and 2011, respectively. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Certain Significant Risks and Uncertainties  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company operates in a rapidly changing environment that involves a number of risks, some of which are beyond the Company's control
that could have a material adverse effect on the Company's business, operating results, and financial condition. These risks include, among others, the Company's: history of losses, and ability to
achieve profitability in the future; highly competitive environment with large established competitors; ability to maintain high subscription renewal rates and sell additional solutions to current
subscribers; ability to maintain demand for its solutions if there is significant migration of on-premise corporate email systems to the cloud or if new messaging and collaboration
technologies cause a decline in the use of email; ability to protect its customers from security breaches; and potential data losses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Use of Estimates  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates and such difference may be material to the financial statements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Cash and Cash Equivalents  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company considers all highly liquid instruments purchased with an original maturity date of 90&nbsp;days or less from the date of
purchase to be cash equivalents. Cash equivalents consist of money market funds. Cash equivalents were $4,270 and $8,660 as of December 2009 and 2010, respectively, and $2,776 of September&nbsp;30,
2011 (unaudited). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Short-term Investments  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Short-term investments consist of readily marketable securities with remaining maturity of more than three months from the
date of purchase and include
commercial paper, corporate bonds, and debt securities. At December&nbsp;31, 2009, 2010 and September&nbsp;30, 2011 (unaudited), all of the Company's short-term investments were
classified as available-for-sale and were carried at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive loss. Realized
gains and losses are included in "other income (expense), net." Fair value is estimated based on available market information. The cost of securities sold is based on the specific identification
method. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Inventories  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Inventories are stated at lower of cost or market value, with costs computed on a first-in, first-out basis.
Cost is determined using standard costs which approximate actual costs. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net
realizable values when they are determined to be less than cost. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Inventories
held at December&nbsp;31, 2009, 2010 and the nine months ended September&nbsp;30, 2011 (unaudited) consists of finished goods. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Revenue Recognition  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company derives its revenue primarily from two sources: (1)&nbsp;subscription revenue for rights related to the use of the
security-as-a-service platform and (2)&nbsp;hardware, training and professional services revenue provided to customers related to their use of the platform.
Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to three years, and consist of (i)&nbsp;subscription fees from the
licensing of the security-as-a-service platform, (ii)&nbsp;subscription fees for access to the on-demand elements of the platform and
(iii)&nbsp;subscription fees for the right to access the company's customer support services. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company applies the provision of ASC 985-605, "Software Revenue Recognition," and related interpretations, to all transactions involving the licensing of software, as
well as related support, training, and other professional services. ASC 985-605 requires revenue earned on software arrangements involving multiple elements such as software license,
support, training and other professional services to be allocated to each element based on the relative fair values of these elements. The fair value of an element must be based on vendor-specific
objective evidence ("VSOE") of fair value. VSOE of fair value of each element is based on the price charged when the element is sold separately. Revenue is recognized when all of the following
criteria are met as set forth in ASC 985-605: </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company has analyzed all of the elements included in its multiple element arrangements and has determined that it does not have sufficient VSOE of fair value to allocate revenue to
its subscription and software license agreements, support, training, and professional services. The Company defers all revenue under the software arrangement until the commencement of the subscription
services and any associated professional services. Once the subscription services and the associated professional services have commenced, the entire fee from the arrangement is recognized ratably
over the remaining period of the arrangement. If the professional services are essential to the functionality of the subscription, then the revenue recognition does not commence until such services
are completed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
hosted on-demand service agreements do not provide customers with the right to take possession of the software supporting the hosted service. The Company recognizes
revenue from its hosted on-demand services in accordance with ASC 605-20, and as such recognizes revenue when the following criteria are met: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Concurrently,
the FASB amended the accounting guidance for revenue recognition ("ASU 2009-14") to exclude hardware appliances containing software components and hardware
components that function together to deliver the hardware appliance's essential functionality from the scope of the software revenue recognition guidance of ASC 985-605. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company elected to adopt this new guidance in the first quarter of fiscal 2011 for new and materially modified revenue arrangements originating after January&nbsp;1, 2011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior
to the adoption of ASU 2009-14, revenue derived from hardware appliance sales were recognized based on the software revenue recognition guidance. The Company could not
establish VSOE of fair value for the undelivered elements in the arrangement, and therefore the entire fee from the arrangement was recognized ratably over the contractual term of the agreement. In
addition, the Company was unable to establish VSOE of fair value of its hosted on-demand service agreements, and therefore the entire fee for the agreement was recognized ratably over the
contractual term of the agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of the adoption of this accounting guidance, revenue derived from our subscription services and hardware appliance sales are no longer subject to industry-specific software
revenue recognition guidance. For all arrangements within the scope of these new accounting pronouncements, including the Company's hosted on-demand services, the Company evaluates each
element in a multiple element arrangement to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when the delivered item has standalone
value and delivery of the undelivered element is probable and within the Company's control. Revenue derived from the licensing of the security-as-a-service platform
continue to be accounted for in accordance with the industry specific revenue recognition guidance. </FONT></P>

appliance revenue is recognized upon shipment. Subscription and support revenue are recognized over the contract period commencing on the start date of the contract.
Professional services and training, when sold with hardware appliances or subscription and support services, are accounted for separately when those services have standalone value. In determining
whether professional services and training services can be accounted for separately from subscription and support services, the Company considers the following factors: availability of the services
from other vendors, the nature of the services, and the dependence of the subscription services on the customer's decision to buy the professional services. If professional services and training do
not qualify for separate accounting, the </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2><B> Deferred Revenue  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the sale of the Company's
subscription fees, and training and professional services. Once the revenue recognition criteria are met, this revenue is recognized ratably over the term of the associated contract, which typically
range from 12 to 36&nbsp;months. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Deferred product costs are the incremental costs that are directly associated with each noncancelable customer contract or hosting
agreement and primarily consist of cost of appliances and royalty payments made to third parties, from whom the Company has obtained licenses to integrate certain software into its products. The costs
are deferred and amortized over the noncancelable term of the related customer contract or hosting agreement, which typically range from 12 to 36&nbsp;months. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Software Development Costs  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We capitalize certain software development costs, including the costs to develop new software solutions or significant enhancements to
existing solutions, which are developed or obtained for internal use. We capitalize software development costs when application development begins, it is probable that the project will be completed,
and the software will be used as intended. Such capitalized costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is generally two years.
Costs associated with preliminary project stage activities, training, maintenance and all post implementation stage activities are expensed as incurred. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Software
development costs related to software services to be sold are capitalized when technological feasibility has been established. Amortization of capitalized software development
costs will begin as each product is available for general release to customers. Amortization will be computed on an individual solution basis for those solutions available for market and will be
recognized based on the solution's economic life. Because the Company believes its current process for developing software is essentially completed concurrently with the establishment of technology
feasibility. Costs associated with the development work between technological feasibility and the general availability has not been material and as such we have not capitalized any development costs
to date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated
useful life of the related asset, which is generally one to three years. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the lease
term or the estimated useful life of the asset or improvement. Cost of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. When property
and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is included in the other income
(expense), net, in the consolidated statement of operations during the period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In accordance with ASC 360, "Property, Plant, and Equipment," the Company evaluates long-lived assets, such as property and
equipment, including intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.
Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be
impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. No assets were determined to be impaired to date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Expenses related to advertising and promotion of solutions is charged to sales and marketing expense as incurred. The Company did not
incur any significant advertising and promotion expenses during the years ended December&nbsp;31, 2008, 2009 and 2010, and for the nine months ended September&nbsp;30, 2010 (unaudited) and 2011

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Goodwill represents the excess of the purchase price of the acquired enterprise over the fair value of identifiable assets acquired and
liabilities assumed. The Company applies ASC 350, "Intangibles&#151;Goodwill and Other," and performs an annual goodwill impairment test. For the purposes of impairment testing, the Company has
determined that it has one reporting unit. A two-step impairment test of goodwill is required pursuant to ASC 350-20-35. In the first step, the fair value of the
reporting unit is compared to its carrying value. If the fair value exceeds the carrying value, goodwill is not impaired and further testing is not required. If the carrying value exceeds the fair
value, then the second step of the impairment test is required to determine the implied fair value of the reporting </FONT></P>

goodwill. The implied fair value of goodwill is calculated by deducting the fair value of all tangible and intangible net assets of the reporting unit, excluding goodwill, from the fair value
of the reporting unit as determined in the first step. If the carrying value of the reporting unit's goodwill exceeds its implied fair value, then an impairment loss must be recorded that is equal to
the difference. The identification and measurement of goodwill impairment involves the estimation of the fair value of the Company. The estimate of fair value of the Company, based on the best
information available as of the date of the assessment, is subjective and requires judgment, including management assumptions about expected future revenue forecasts and discount rates. No impairment
to the carrying value of goodwill was identified by the Company during the years ended December&nbsp;31, 2009 and 2010 or the nine months ended September&nbsp;30, 2011 (unaudited). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company has elected to use the "with and without" approach as described in ASC 740-20, "Intraperiod Tax Allocation," in determining the order in which tax attributes are
utilized. As a result, the Company will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax
attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the impact of stock-based awards on other tax attributes, such as the research tax
credit, through the consolidated statement of operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective
January&nbsp;1, 2009, the Company adopted the accounting guidance for uncertainties in income taxes, which prescribes a recognition threshold and measurement process for
recording uncertain tax positions taken, or expected to be taken in a tax return, in the financial statements. Additionally, the guidance also prescribes new treatment for the derecognition,
classification, accounting in interim periods and disclosure requirements for uncertain tax positions. The Company accrues for the estimated amount of taxes for uncertain tax positions if it is more
likely than not that the Company would be required to pay such additional taxes. An uncertain tax position will not be recognized if it has a less than 50% likelihood of being sustained. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company recognizes interest and penalties related to tax positions in income tax expense. To the extent that accrued interest and penalties do not ultimately become payable, amounts
accrued will be reduced and reflected as a reduction of the overall income tax provision in the period that such determination is made. No interest or penalties have been accrued for any period
presented. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Employee Benefit Plans  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company sponsors a 401(k) defined contribution plan covering all employees. The Company may make discretionary contributions to the
401(k). To date, no contributions have been made by the Company. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Stock-Based Compensation  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company accounts for stock-based compensation under ASC 718, "Compensation&#151;Stock Compensation" using the
prospective transition method prescribed for private companies. Using the prospective transition method, compensation expense recognized includes the compensation cost for all share-based payment
awards granted to employees subsequent to December&nbsp;31, 2005, based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company uses the
Black-Scholes option pricing model to determine the fair value of stock options. Stock compensation expense is recognized on a straight-line basis over the requisite service period of the
award, which generally equals the vesting period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
ASC 718, the Company is required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures is computed based
on historical data of employee turnover and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in
estimated forfeitures are recognized in the period of change and will impact the amount of stock compensation expenses to be recognized in future periods. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amended guidance eliminates one of the
presentation options provided by current U.S.&nbsp;GAAP that is to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, it
gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
September 2011, the Financial Accounting Standards Board (the "FASB") issued amended guidance relating to the goodwill impairment test. The guidance allows an entity an option to
first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under that option, an entity no longer would be
required to calculate the fair value of a reporting unit unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its
carrying amount. The guidance also includes examples of the types of events and circumstances to consider in conducting the qualitative assessment. The guidance will be effective for annual and
interim goodwill impairment tests performed for fiscal years beginning after December&nbsp;15, 2011. Early adoption is permitted. We are currently evaluating the impact of this amended guidance on
our consolidated financial statements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the Fortiva Agreement, the acquisition was closed in exchange for cash payment of $5,460, cash settlement of Fortiva's outstanding debt for $1,267, issuance to the
former shareholders of Fortiva of 3,100 shares of Series&nbsp;F preferred stock at its fair value of $16,492 ($5.32 per share). The purchase consideration also included the acquisition related costs
of $1,031. The results of Fortiva's operations have been included in the consolidated financial statements since the acquisition date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the Sigaba Agreement, the Company paid total consideration of $461 for the assets. In addition, the Company agreed to pay an additional 20% of the "renewal fees," as
specified in
the Sigaba Agreement, actually collected by the Company from each existing Sigaba customer upon renewal up to a maximum of $150. The minimum amount due to Sigaba under the term of above agreement was
$75 as of December&nbsp;31, 2008, which was recorded to operating expenses in fiscal year 2008. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On October&nbsp;21, 2009, the Company entered into an Agreement of Merger (the "EDN&nbsp;Agreement") with Everyone.net,&nbsp;Inc.
("EDN"), a California corporation, by which the Company acquired 100% of the outstanding shares of EDN. Under the terms of the EDN Agreement, the acquisition was closed in exchange for cash payment of
$5,496, cash settlement of EDN's outstanding debts totaling $1,330, issuance of 188 shares of Series&nbsp;F preferred stock at its fair value of $1,000 ($5.32 per share). Additionally, the Company
agreed to pay additional earn-out consideration ("earn-out") of up to $2,000 through November 2011, such earn-out being contingent upon the achievement of specified
financial targets. The initial fair value of the earn-out of $1,495 was recorded as part of the purchase consideration. The change in fair value of the earn-out of $208 during
the nine months ended September&nbsp;30, 2011, was recognized as a charge to interest income (expense), net for the year. The acquisition related costs of $559 incurred by the Company was charged to
operating expense in the year ended December&nbsp;31, 2009. The results of EDN's operations have been included in the consolidated financial statements since the acquisition date. During the year
ended December&nbsp;31, 2010, the Company paid $1,000 of earn-out to the sellers. The remaining payout of $1,000 will be paid in December 2011 and is fully accrued for at
September&nbsp;30, 2011 given that the performance criteria had been met at September&nbsp;30, 2011. The Company also received $180 during the year ended December&nbsp;31, 2010, in a working

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company limits its concentration of risk in cash equivalents and short-term investments by diversifying its investments among a variety of industries and issuers and by
limiting the average maturity to one year or less. The Company's professional portfolio managers adhere to this investment policy as approved by the Company's board of directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company's investment policy is to invest only in fixed income investments denominated and payable in U.S. dollars. Investment in obligations of the U.S. government and its agencies,
money market instruments, commercial paper, certificates of deposit, bankers' acceptances, corporate bonds of U.S. companies, municipal securities and asset backed securities are allowed. The Company
does not invest in auction rate securities, futures contracts, or hedging instruments. </FONT></P>

Company's accounts receivables are derived from revenue earned from customers primarily located in the United States of America. The Company performs periodic evaluations of its
customers' financial condition and generally does not require its customers to provide collateral or other security to support accounts receivable, and maintains an allowance for doubtful accounts.
Credit losses historically have not been significant. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
of December&nbsp;31, 2009, 2010 and September&nbsp;30, 2011 (unaudited), all investments mature in less than one year. Estimated fair values for marketable securities are based on
quoted market prices for the same or similar instruments. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Fair Value Measurements  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e.,&nbsp;the "exit
price") in an orderly transaction between market participants at the measurement date. A hierarchy for inputs used in measuring fair value has been defined to minimize the use of unobservable inputs
by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data.
Unobservable inputs are inputs that reflect the Company's assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in
the circumstances. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
fair value hierarchy prioritizes the inputs into three broad levels: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the indemnification provisions of the Company's customer agreements, the Company agrees to indemnify and defend and hold harmless
its customers against, among other things, infringement of any patent, trademark or copyright under any country's laws or the misappropriation of any trade secret arising from the customers' legal use
of the Company's solutions. The exposure to the Company under these indemnification provisions is generally limited to the total amount paid by the customers under the applicable customer agreement.
However, certain indemnification provisions potentially expose the Company to losses in excess of the aggregate amount paid to the Company by the customer </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Legal Contingencies  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;From time to time, the Company is involved in claims and legal proceedings that arise in the ordinary course of business. Based on
currently available information, management does not believe that the ultimate outcome of these unresolved matters, individually and in the aggregate, is likely to have a material adverse effect on
the Company's financial position, results of operations or cash flows. However, litigation is subject to inherent uncertainties and the Company's view of these matters may change in the future. Were
an unfavorable outcome to occur, there exists the possibility of a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the
unfavorable outcome occurs, and potentially in future periods. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Equipment Financing Loans  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company entered into a new equipment loan agreement with Silicon Valley Bank in April 2011 for an aggregate loan principle amount
of $6,000. Interest on the advances are equal to prime rate plus 0.50%. As of September&nbsp;30, 2011, the interest on the advances was 4.50%. The Company has the ability to draw down on this
equipment line through April&nbsp;19, 2012. Each drawn amount is due 48&nbsp;months after funding. Borrowings outstanding under the equipment loan at September&nbsp;30, 2011 were $2,926
(unaudited). Equipment financed under this loan arrangement is collateralized by the respective assets underlying the loan. The terms of the loan restrict the Company's ability to pay dividends. The
loan includes a covenant that requires the Company to maintain cash and cash equivalents plus net accounts receivables of at least two times the amount of all outstanding indebtedness. As of
September&nbsp;30, 2011 (unaudited), the Company was in compliance with the financial covenant. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company had a previous equipment loan arrangement with Silicon Valley Bank for $2,000. The loan bore interest at an annual rate of 8.75%. The maturity date was 36&nbsp;months after
the funding date. Borrowings outstanding under the equipment loan at December&nbsp;31, 2010 and September&nbsp;30, 2011 were $67 and $0 (unaudited), respectively. Equipment financed under this
loan arrangement was collateralized by the respective assets underlying each specific draw down. This loan required the Company to maintain a tangible net worth greater than $18,000. As of
December&nbsp;31, 2010, the Company was in compliance with the financial covenant. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest
expense for the years ended December&nbsp;31, 2008, 2009 and 2010 and the nine months ended September&nbsp;30, 2010 and 2011 was approximately $85, $48, $27, $25 (unaudited)
and $37 (unaudited), respectively. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Dividends  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The holders of Series&nbsp;A, B, C, D, E and F preferred stock are entitled to receive noncumulative dividends prior and in
preference to any declaration or payment of any dividend on the common stock of the Company, at the per annum rate of $0.08, $0.1024, $0.1926, $0.2408, $0.2786 and $0.4256 per share, respectively,
when and if declared by the Board of Directors. Dividends on preferred stock or common stock have never been declared by the Board of Directors. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Liquidation  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the event of liquidation, dissolution or winding-up of the Company, either voluntary or involuntary, the holders of the
preferred stock are entitled to receive, prior to and in preference to any distribution of any of the assets of the Company to the holders of common stock by reason of ownership thereof, an amount per
share equal to $1.00, $1.28, $2.41, $3.01, $3.48 and $5.32 plus any declared but unpaid dividends to the holders of Series&nbsp;A, B, C, D, E and F preferred stock, respectively. If the assets and
funds distributed among the holders of Series&nbsp;A, B, C, D, E and F preferred stock are insufficient to permit the payment to such holders of the full amounts, then the entire assets and funds of
the Company shall be distributed ratably among the holders of Series&nbsp;A, B, C, D, E and F preferred stockholders. The remaining assets, if any, shall be distributed to the common stockholders.
These liquidity features cause the Company's convertible preferred stock to be classified as mezzanine equity rather than as a component of stockholders' deficit. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2><B> Conversion  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Each share of Series&nbsp;A, B, C, D, E and F preferred stock is convertible at the option of the holder into such number of shares
of common stock as is determined by dividing $1.00, $1.28, $2.41, $3.01, $3.48 and $5.32, respectively, by the conversion price applicable to such share, determined in effect on the date the
certificate is surrendered for conversion. The conversion price for each share of Series&nbsp;A, B, C, D, E and F preferred stock was $1.00, $1.28, $2.41, $2.41, $3.47, and $5.32, respectively. Such
initial conversion price shall be subject to adjustment for stock splits, reverse stock splits, stock dividends and other matters. Each share of Series&nbsp;A, B, C and F preferred stock is
convertible on a 1:1 basis into common stock. Series&nbsp;D preferred stock is convertible into 1.25 shares of common stock and each share of Series&nbsp;E preferred stock is convertible into
1.00463 shares of common stock. The shares of preferred stock are automatically converted into shares of common stock at the conversion price in effect upon the earlier of a closing of an initial
public offering of common stock in which the gross proceeds exceeds $40,000 and in which the public offering price per share equals or exceeds $10.64 per share, or the date specified by the holders of
a majority of the outstanding shares of the preferred stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Redemption  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The convertible preferred stock is not redeemable by the Company or at the option of the preferred stockholders. </FONT></P>

$1.28 per share in connection with an equipment financing arrangement. Using the Black-Scholes option-pricing model, the Company determined the fair value of each warrant to be $1.07 and $2.01 as of
December&nbsp;31, 2009 and 2010, respectively. The fair value of the warrants was estimated using the following assumptions. </FONT></P>

repurchased 326 shares of common stock prior to 2009, which had been early exercised, which were pending retirement at December&nbsp;31, 2010 and 2009. Accordingly 6,924, 7,968 and 8,593 (unaudited)
shares of common stock were issued and 6,598, 7,657 and 8,268 (unaudited) shares of common stock were outstanding at December&nbsp;31, 2009 and 2010 and September&nbsp;30, 2011, respectively. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A
portion of the shares sold are subject to a right of repurchase by the Company subject to vesting, which is generally over a four year period from the earlier of grant date or employee
hire date, as applicable, until vesting is complete. There was no repurchase of common stock during the years ended December&nbsp;31, 2009 and 2010 and the nine months ended September&nbsp;30,
2011 (unaudited). At December&nbsp;31, 2009 and 2010 and September&nbsp;30, 2011 (unaudited), there were 14, 10 and 5 shares, respectively, subject to repurchase. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Company had, prior to 2009, granted a warrant to a service provider to purchase 4 shares of common stock in exchange for services performed. Such warrant for common stock issued by
the Company is outstanding at September&nbsp;30, 2011 (unaudited). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> 11. Stock Option Plan  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the Company's 2002 stock option plan (the "Plan"), the Company may grant options to purchase common stock or directly issue shares of common stock to employees, outside directors
and consultants at prices equal to the fair market value at the date of grant of options or issue of common stock. The Company has the right to repurchase any unvested shares (at the option exercise
price) of common stock issued directly or under option exercises. The right of repurchase generally expires over the vesting period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The fair value of options granted is estimated on the grant date using the Black-Scholes option valuation model. This valuation model
for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time
that the options granted are expected to be outstanding), the volatility of the common stock price, an assumed risk-free interest rate and the estimated forfeitures of unvested stock
options. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded
for options that do not vest and the compensation cost from vested options, whether forfeited or not, is not reversed. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Board of Directors determined the fair market values of the Company's common stock, in good faith and based on the best information available to the Board and the Company's
management at the time of grant. The Company performed its analysis in accordance with applicable elements of the
practice aid issued by the American Institute of Certified Public Accountants entitled </FONT><FONT SIZE=2><I>Valuation of Privately Held Company Equity Securities Issued as
Compensation</I></FONT><FONT SIZE=2>. The procedures performed to determine the fair value of the Company's common stock was based on a probability-weighted expected return method to estimate the
aggregate equity value of the Company. </FONT></P>

(SAB&nbsp;107). The Company does not have significant historical share option exercise experience and hence considers the expected term assumption calculated using the simplified method to be
reasonable. Since the Company's stock is not publicly traded, the stock volatility assumptions represent an estimate of the historical volatilities of the common stock of a group of publicly-traded
peer companies that operate in a similar industry. The estimate was determined based on the average historical volatilities of these peer companies. The risk-free interest rate used was

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our basic net loss per share of common stock is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period. The
weighted-average number of shares of common stock used to calculate our basic net loss per share of common stock excludes those shares subject to repurchase related to stock options that were
exercised prior to vesting as these shares are not deemed to be issued for accounting purposes until they vest. The diluted net loss per share of common stock is computed by dividing the net loss
using the weighted-average
number of shares of common stock, excluding common stock subject to repurchase, and, if dilutive, potential shares of common stock outstanding during the period. Potential shares of common stock
consist of common stock subject to repurchase and stock options to purchase common stock and warrants to purchase convertible preferred stock (using the treasury stock method) and the conversion of
our convertible preferred stock and convertible notes payable (using the "if converted" method). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pro forma basic and diluted net loss per share of common stock has been computed to give effect to the conversion of the convertible preferred stock into common stock as of the later of
January&nbsp;1, 2010 or the issuance date. As discussed in Note&nbsp;9, the warrants to purchase preferred stock were exercised on a net settlement basis in August 2011. For purposes of this pro
forma presentation of basic and diluted net loss per share of common shares (unaudited), the Company has assumed that the preferred stock warrants were exercised on a net settlement basis on
January&nbsp;1, 2010. Also, the numerator in the pro forma basic and diluted net loss per share calculation has been adjusted to remove gains and losses resulting from remeasurements of the
convertible preferred stock warrant liability. </FONT></P>

to expire in the year 2018. As of December&nbsp;31, 2009 and 2010, the Company had research credits for federal income tax purposes of approximately $2,000 and $2,700, respectively. The
research and development credits will begin to expire in the year 2022. In addition, as of December&nbsp;31, 2009 and 2010, the Company had net operating loss carryforwards and research and
development tax credits for state income tax purposes of approximately $72,000 and $77,900 respectively. The state net operating loss carryforwards expire at varying amounts beginning in the year
2011. As of December&nbsp;31, 2009 and 2010, the Company had state research and development carryforwards of $2,500 and $3,200 which will carryforward indefinitely. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Utilization
of the net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state
provisions. An analysis was conducted through 2009 to determine whether an ownership change had occurred since inception. The analysis indicated that although an ownership change occurred in a prior
year, the net operating losses and research and development credits would not expire before utilization. In the event the Company has subsequent changes in ownership, net operating losses and research
and development credit carryovers could be limited and may expire unutilized. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective
January&nbsp;1, 2009, the Company adopted the provisions of FASB's guidance on accounting for uncertainty in income taxes. This provides a comprehensive model for the
recognition, measurement and disclosure in financial statements of uncertain income tax positions that a company has taken or expects to take on a tax return. Under these provisions, a company can
recognize the benefit of an income tax position only if it is more likely than not (greater than 50%) that the tax position will be sustained upon tax examination, based solely on the technical merits
of the tax position. Otherwise, no benefit can be recognized. Assessing an uncertain tax position begins with the initial determination of the position's sustainability and is measured at the largest
amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain
tax positions must be reassessed. Additionally, companies are required to accrue interest and related penalties, if applicable, on all tax exposures for which reserves have been established consistent
with jurisdictional tax laws. The cumulative effect of this adoption is recorded as an adjustment to the opening balance of its accumulated deficit on the adoption date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
a result of the implementation of these provisions, the Company recognized a $820 increase in its unrecognized tax benefits. There was no increase in the January&nbsp;1, 2009
balance of accumulated deficit since the benefit relates to attribute carryovers for which the related deferred tax asset was subject to a full valuation allowance. At the adoption date of
January&nbsp;1, 2009 and as of December&nbsp;31, 2010, the Company had no accrued interest or penalties related to the tax contingencies. Since the unrecognized tax benefit relates to attribute
carryovers for which the deferred tax asset was subject to a full valuation allowance, the recognition of the unrecognized tax benefits will not affect the Company's effective tax rate. The Company
has elected to recognize interest and penalties as a component of income tax expense. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at
December&nbsp;31, 2010 will significantly increase or decrease within the next twelve months. Because of net operating loss and credit carryforwards, all of the Company's tax years, dating to
inception in 2002 remain open to tax examination in all major tax jurisdictions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law authorizes a court to award, or a corporation's board of directors to grant,

to the closing of the offering that is the subject of this Registration Statement, the Registrant intends to enter into indemnification agreements with each of its current
directors and executive officers to provide these directors and executive officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant's restated
certificate of incorporation and restated bylaws and to provide additional procedural protections. At present, there is no pending litigation or proceeding involving a director, executive officer or
employee of the Registrant regarding which indemnification is sought. Reference is also made to Section&nbsp;8 of the Underwriting Agreement, which provides for the indemnification of executive
officers, directors and controlling persons of the
Registrant against certain liabilities. The indemnification provisions in the Registrant's restated certificate of incorporation and restated bylaws and the indemnification agreements entered into or
to be entered into between the Registrant and each of its directors and executive officers is sufficiently broad to permit indemnification of the Registrant's directors and executive officers for
liabilities arising under the Securities Act. </FONT></P>

described in Item&nbsp;14 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. </FONT></P>

PROSPECTUS SUMMARY
This summary highlights selected information contained elsewhere in this prospectus. This summary does not

consolidated financial statements and related notes included elsewhere in this prospectus, before making an investment in our common stock.
Company Overview
Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most sensitive data. Our security-as-a-service platform is comprised of
an integrated suite of on-demand data protection solutions, including
threat protection, regulatory compliance, archiving and governance, and secure communication. Our solutions are built on a flexible, cloud-based platform and leverage a number of proprietary
technologies, including big data analytics, machine learning, deep content inspection, secure storage and advanced encryption, to address today's rapidly changing threat landscape.
A
fundamental shift in the sources of cyber crime, from hackers to organized crime and governments, combined with the emergence of international data trafficking, are driving an
unprecedented wave of targeted, malicious attacks designed to steal valuable information. At the same time, the growth of business-to-business collaboration, as well as the consumerization of IT and
the associated adoption of mobile devices and unmanaged Internet-based applications, have proliferated sensitive data and reduced the effectiveness of many existing security products. These factors
have contributed to an increasing number of severe data breaches and expanding regulatory mandates, all of which have accelerated demand for effective data protection and governance solutions.
Our
platform addresses this growing challenge by not only protecting data as it flows into and out of the enterprise via on-premise and cloud-based email, instant messaging, social media
and other web-based applications, but also securely archiving these communications for compliance and discovery. We address four important problems for the
enterprise:
•
Keeping malicious content out;
•
Preventing the theft or inadvertent loss of sensitive information and, in turn, ensuring compliance with regulatory data
protection mandates;
•
Collecting, retaining, governing and discovering sensitive data for compliance and litigation support; and
•
Securely sharing sensitive data with customers, partners and suppliers.
Our
platform and its associated solutions are sold to customers on a subscription basis and can be deployed through our unique cloud-based architecture that leverages both our global
data centers as well as optional points-of-presence behind our customers' firewalls. Our
flexible deployment model enables us to deliver superior security and compliance while maintaining the favorable economics afforded by cloud computing, creating a competitive advantage for us over
legacy on-premise and cloud-only offerings.
Our
solutions are used by approximately 2,400 customers worldwide, including 24 of the Fortune 100, protecting tens of millions of end-users. We market and sell our solutions worldwide
both directly through our sales teams and indirectly through a hybrid model where our sales organization actively assists our network of distributors and resellers. We also distribute our solutions
through strategic partners including International Business Machines Corp. (IBM), Microsoft Corporation and VMware, Inc.

Industry Background
A number of trends are leading to a significant shift in the nature and severity of data security threats and the measures required to
address them:
•
Data security attacks are becoming more sophisticated and
targeted.
Professional criminals, governments and "hacktivists" are increasingly pursuing sensitive information, causing threats to
shift from generic malware and high-volume spam to more targeted attacks, including "spear phishing" attacks, focused on high-value financial data.
•
Consumerization of IT and growth of business-to-business collaboration increases risk of data
loss.
The widespread adoption of consumer technologies in the enterprise and the increasing need for business partners to exchange
sensitive data make it more challenging for enterprises to control and govern their data.
•
Consequences of data breaches have become more severe.
The
monetary and reputational cost of data breaches, whether malicious or inadvertent, is increasing rapidly. An ongoing wave of high profile breaches in multiple industries has exposed a broad range of
data, including personal information, diplomatic communications, online banking credentials, financial accounts and health care records.
•
Regulatory mandates create additional data protection and governance
requirements.
Governments around the world and at all levels of jurisdiction are continuing to enact new laws regarding data protection
and privacy as well as new regulations to mandate closer oversight over all aspects of regulatory compliance.
To
protect their data assets, organizations have typically employed a number of disparate on-premise security products. However, these solutions are not well suited to
addressing today's challenges and many organizations are still unable to adequately protect their data assets for a variety of reasons, including:
•
Legacy threat protection products are increasingly vulnerable to modern targeted
attacks.
Widely deployed threat protection products are often ineffective against today's more advanced, targeted attacks.
•
Siloed, reactive security and compliance offerings provide inadequate data
protection.
Legacy security architectures lack the integration and common policy framework to effectively protect and govern data across
the enterprise.
•
Traditional security architectures assume data is behind corporate
firewalls.
With the consumerization of IT and the associated adoption of mobile devices and cloud-based applications, valuable corporate
data is now widely distributed. Legacy systems are unable to provide adequate data protection in this new environment because they are not designed to apply data loss prevention technologies to
webmail, Internet-based collaboration applications or social networking sites.
•
Inflexible, cumbersome security and compliance systems are often bypassed by
end-users.
Most existing solutions are inflexible, cumbersome to use, and hinder end-users'
day-to-day business activities, all of which lead end-users to bypass them.
•
Discrete, hardware-based offerings have high total cost of
ownership.
Traditional on-premise security and archiving products are time consuming to deploy and manage, require redundancy and excess
capacity to handle peak-level workloads, and are difficult and expensive to upgrade.

Market Opportunity
In an attempt to defend against the constantly evolving threat landscape and to comply with government mandates, enterprises are
beginning to implement new, more robust corporate policies for data protection, archiving and governance. To enforce these new policies, secure communication technologies and policy-based encryption
are being used to limit the leakage of sensitive data and intellectual property, and archiving and eDiscovery solutions are being used to reduce legal compliance risks. According to International Data
Corporation (IDC), a third-party market research company, the total worldwide market for data protection solutions is estimated to grow from $5.2 billion in 2011 to $8.0 billion by 2015,
a compound annual growth rate (CAGR) of 11%.*

solutions are built on a cloud-based architecture, protecting data not only as it flows into and out of the enterprise via on-premise and cloud-based email, instant messaging, social media and other
web-based applications, but also securely archiving these communications for compliance and discovery. We have pioneered the use of innovative technologies to deliver better

detect targeted "zero-hour" attacks in realtime and quarantine them appropriately.
•
Comprehensive, integrated data protection suite.
We offer
a comprehensive solution for data protection and governance through an integrated, security-as-a-service platform that improves an organization's ability to detect
and mitigate inbound and outbound threats and securely archive and discover communication across all major communication channels including email, instant messaging, social media and other
web-based applications.
•
Designed to empower end-users.
Our solutions
actively enable secure, business-to-business and business-to-consumer communications and make it easy for end-users to share information.
•
Security optimized cloud architecture.
Our multi-tenant
security-as-a-service solution enables us to leverage the benefits of the cloud to cost-effectively deliver superior security and compliance while
optimizing each deployment for the customer's unique threat environment.
•
Extensible security-as-a-service
platform.

Reconciliation of Non-GAAP Financial Measures
Adjusted subscription gross profit
We have included adjusted subscription gross profit, a non-GAAP financial measure, in this prospectus because it is a key measure used
by our management and board of directors to understand and evaluate our operating results, core operating performance, and trends to prepare and approve our annual budget and to develop short- and
long-term operational plans. We have provided a reconciliation between subscription gross profit, the most directly comparable GAAP financial measure, and adjusted subscription gross
profit. We believe that adjusted
subscription gross profit provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors.
Our
use of adjusted subscription gross profit has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as
reported under GAAP. Because of these limitations, you should consider adjusted subscription gross profit alongside other financial performance measures, including subscription gross profit and our
other GAAP results.

Billings
We have included billings, a non-GAAP financial measure, in this prospectus because it is a key measure used by our management and
board of directors to manage our business and monitor our near term cash flows. We have provided a reconciliation between total revenue, the most directly comparable GAAP financial measure, and
billings. Accordingly, we believe that billings provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board
of directors.
Our
use of billings as a non-GAAP measure has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for revenue or an analysis of
our results as reported under GAAP. Some of these limitations are:
•
Billings is not a substitute for revenue, as trends in billings are not directly correlated to trends in revenue except
when measured over longer periods of time;
•
Billings is affected by a combination of factors including the timing of renewals, the sales of our solutions to both new
and existing customers, the relative duration of contracts sold, and the relative amount of business derived from strategic partners. As each of these elements has unique characteristics in the
relationship between billings and revenue, our billings activity is not closely correlated to revenue except over longer periods of time; and
•
Other companies, including companies in our industry, may not use billings, may calculate billings differently, or may use
other financial measures to evaluate their performance - all of which reduce the usefulness of billings as a comparative measure.

Adjusted EBITDA
We have included adjusted EBITDA, a non-GAAP financial measure, in this prospectus because it is a key metric used by our management
and board of directors to measure operating performance and trends and to prepare and approve our annual budget. We define adjusted EBITDA as net loss, adjusted to exclude: depreciation, amortization
of intangibles, interest income (expense), net, provision for income taxes, stock-based compensation, acquisition-related expense, other income, and other expense. We believe that the use of adjusted
EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance
across companies and across periods. We believe that:
•
Adjusted EBITDA provides investors and other users of our financial information consistency and comparability with our
past financial performance, facilitates period-to-period comparisons of operations and facilitates comparisons with our peer companies, many of which use similar
non-GAAP financial measures to supplement their GAAP results; and
•
It is useful to exclude certain non-cash charges, such as depreciation, amortization of intangible assets and
stock-based compensation and non-core operational charges, such as acquisition-related expenses, from adjusted EBITDA because the amount of such expenses in any specific period may not be
directly correlated to the underlying performance of our business operations and these expenses can vary significantly between periods as a result of new acquisitions, full amortization of previously
acquired tangible and intangible assets or the timing of new stock-based awards, as the case may be.
We
use adjusted EBITDA in conjunction with traditional GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the
preparation of
our annual operating budget, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance.
We
do not place undue reliance on adjusted EBITDA as our only measures of operating performance. Adjusted EBITDA should not be considered as a substitute for other measures of financial
performance reported in accordance with GAAP. There are limitations to using non-GAAP financial measures, including that other companies may calculate these measures differently than we
do, that they do not reflect our capital expenditures or future requirements for capital expenditures and that they do not reflect changes in, or cash requirements for, our working capital.

RISK FACTORS
Investing in our common stock involves a high degree of risk. You should carefully consider the following risk
factors, as well as the other information in this prospectus, before deciding whether to invest in shares of our common stock. The occurrence of any of the events described below could harm our
business, financial condition, results of operation and growth prospects. In such an event, the trading price of our common stock may decline and you may lose all or part of your investment.
Risks Related to Our Business and Industry
We have a history of losses, and we are unable to predict the extent of any future losses or when, if ever, we will achieve profitability in the future.
We have incurred net losses in every year since our inception, including net losses of $19.7 million and $20.9 million in
2009 and 2010, respectively. We also had a net loss of $13.7 million in the nine months ended September 30, 2011. As a result, we had an accumulated deficit of $155.7 million as
of September 30, 2011. Achieving profitability will require us to increase revenue, manage our cost structure, and avoid unanticipated liabilities. We do not expect to be profitable in the near
term. Revenue growth may slow or revenue may decline for a number of possible reasons, including slowing demand for our solutions, increasing competition, a decrease in the growth of our overall
market, or if we fail for any reason to continue to capitalize on growth opportunities. Any failure by us to obtain and sustain profitability, or to continue our revenue growth, could cause the price
of our common stock to decline significantly.
We operate in a highly competitive environment with large, established competitors, and our competitors may gain market share in the markets for our solutions that could
adversely affect our business and cause our revenue to decline.
Our traditional competitors include security-focused software vendors, such as Symantec Corporation and McAfee, Inc., an Intel
Corporation subsidiary, which offer software products that directly compete with our solutions. In addition to competing with these vendors directly for sales to customers, we compete with them for
the opportunity to have our solutions bundled with the product offerings of our strategic partners. Our competitors could gain market share from us if any of these partners replace our solutions with
the products of our competitors or if these partners more actively promote our competitors' products over our solutions. In addition, software vendors who have bundled our solutions with theirs may
choose to bundle their software with their own or other vendors' software, or may limit our access to standard product interfaces and inhibit our ability to develop solutions for their platform.
We
also face competition from large technology companies, such as Cisco Systems, Inc., EMC Corporation, Google Inc., Hewlett-Packard Company, Intel and Microsoft. These
companies are increasingly developing and incorporating into their products data protection and storage software that compete on various levels with our solutions. Our competitive position could be
adversely affected to the extent that our customers perceive that the functionality incorporated into these products would replace the need for our solutions or that buying from one vendor would
provide them with increased leverage and purchasing power and a better customer experience. We also face competition from many smaller companies that specialize in particular segments of the markets
in which we compete.
Many
of our competitors have greater financial, technical, sales, marketing or other resources than we do and consequently may have the ability to influence our customers to purchase
their products instead of ours. Further consolidation within our industry or other changes in the competitive environment could also result in larger competitors that compete with us on several
levels. In addition, acquisitions of smaller companies that specialize in particular segments of the markets in which we compete by large technology companies would result in increased competition
from these large
12
Table of Contents
technology
companies. For example, Google's acquisition of Postini, an email and web security and archiving service, resulted in Google becoming one of our competitors. If we are unsuccessful in
responding to our competitors or to changing technological and customer demands, our competitive position and financial results could be adversely affected.
If we are unable to maintain high subscription renewal rates, our future revenue and operating results will be harmed.
Our customers have no obligation to renew their subscriptions for our solutions after the expiration of their initial subscription
period, which typically ranges from one to three years. In addition, our customers may renew for fewer subscription services or users, renew for shorter contract lengths or renew at lower prices due
to competitive or other pressures. We cannot accurately predict renewal rates and our renewal rates may decline or fluctuate as a result of a number of factors, including competition, customers' IT
budgeting and spending priorities, and deteriorating general economic conditions. If our customers do not renew their subscriptions for our solutions, our revenue would decline and our business would
suffer.
If we are unable to sell additional solutions to our customers, our future revenue and operating results will be harmed.
Our future success depends on our ability to sell additional solutions to our customers. This may require increasingly sophisticated
and costly sales efforts and may not result in additional sales. In addition, the rate at which our customers purchase additional solutions depends on a number of factors, including the perceived need
for additional solutions, growth in the number of end-users, and general economic conditions. If our efforts to sell additional solutions to our customers are not successful, our business
may suffer.
If our solutions fail to protect our customers from security breaches, our brand and reputation could be harmed, which could have a material adverse effect on our business
and results of operations.
The threats facing our customers are constantly evolving and the techniques used by attackers to access or sabotage data change
frequently. As a result, we must constantly update our solutions to respond to these threats. If we fail to update our solutions in a timely or effective manner to respond to these threats, our
customers could experience security breaches. Many state and foreign governments have enacted laws requiring companies to notify individuals of data security breaches involving their personal data.
These mandatory disclosures regarding a security breach often lead to widespread negative publicity, and any association of us with such publicity may cause our customers to lose confidence in the
effectiveness of our data security measures. Any security breach at one of our customers would harm our reputation as a secure and trusted company and could cause the loss of customers. Similarly, if
a well-publicized breach of data security at a customer of any other cloud-based data protection or archiving service provider or other major enterprise cloud services provider were to
occur, there could be a loss of confidence in the cloud-based storage of sensitive data and information generally.
In
addition, our solutions work in conjunction with a variety of other elements in customers' IT and security infrastructure, and we may receive blame and negative publicity for a
security breach that may have been the result of the failure of one of the other elements not provided by us. The occurrence of a breach, whether or not caused by our solutions, could delay or reduce
market acceptance of our solutions and have an adverse effect on our business and financial performance. In addition, any revisions to our solutions that we believe may be necessary or appropriate in
connection with any such breach may cause us to incur significant expenses. Any of these events could have material adverse effects on our brand and reputation, which could harm our business,
financial condition, and operating results.

Table of Contents
If our customers experience data losses, our brand, reputation and business could be harmed.
Our customers rely on our archive solutions to store their corporate data, which may include financial records, credit card
information, business information, health information, other personally identifiable information or other sensitive personal information. A breach of our network security and systems or other events
that cause the loss or public disclosure of, or access by third parties to, our customers' stored files or data could have serious negative consequences for our business, including possible fines,
penalties and damages, reduced demand for our solutions, an unwillingness of our customers to use our solutions, harm to our brand and reputation, and time-consuming and expensive
litigation. The techniques used to obtain unauthorized
access, disable or degrade service, or sabotage systems change frequently, often are not recognized until launched against a target, and may originate from less regulated or remote areas around the
world. As a result, we may be unable to proactively prevent these techniques, implement adequate preventative or reactionary measures, or enforce the laws and regulations that govern such activities.
In addition, because of the large amount of data that we collect and manage, it is possible that hardware failures, human errors or errors in our systems could result in data loss or corruption, or
cause the information that we collect to be incomplete or contain inaccuracies that our customers regard as significant. If our customers experience any data loss, or any data corruption or
inaccuracies, whether caused by security breaches or otherwise, our brand, reputation and business would be harmed.
Our
errors and omissions insurance may be inadequate or may not be available in the future on acceptable terms, or at all. In addition, our policy may not cover any claim against us for
loss of data or other indirect or consequential damages. Defending a suit based on any data loss or system disruption, regardless of its merit, could be costly and divert management's attention.
Defects or vulnerabilities in our solutions could harm our reputation, reduce the sales of our solutions and expose us to liability for losses.
Because our solutions are complex, undetected errors, failures or bugs may occur, especially when solutions are first introduced or
when new versions or updates are released despite our efforts to test those solutions and enhancements prior to release. We may not be able to correct defects, errors, vulnerabilities or failures
promptly, or at all.
Any
defects, errors, vulnerabilities or failures in our solutions could result in:
•
expenditure of significant financial and development resources in efforts to analyze, correct, eliminate or work around
errors or defects or to address and eliminate vulnerabilities;
•
loss of existing or potential partners or customers;
•
loss or disclosure of our customers' confidential information;
•
loss of our proprietary technology;
•
our solutions being susceptible to hacking or electronic break-ins or otherwise failing to secure data;
•
delayed or lost revenue;
•
delay or failure to attain market acceptance;
•
lost market share;
•
negative publicity, which could harm our reputation; or
•
litigation, regulatory inquiries or investigations that would be costly and harm our reputation.

Table of Contents
Limitation
of liability provisions in our standard terms and conditions may not adequately or effectively protect us from any claims related to defects, errors, vulnerabilities or
failures in our solutions, including as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries.
Because we provide security solutions, our software, website and internal systems may be subject to intentional disruption that could adversely impact our reputation and
future sales.
We could be a target of attacks specifically designed to impede the performance of our solutions and harm our reputation. Similarly,
experienced computer hackers may attempt to penetrate our network security or the security of our website and misappropriate proprietary information and/or cause interruptions of our services. Because
the techniques used by such computer hackers to access or sabotage networks change frequently and may not be recognized until launched against a target, we may be unable to anticipate these
techniques. If an actual or perceived breach of network security occurs, it could adversely affect the market perception of our solutions, and may expose us to the loss of information, litigation and
possible liability. In addition, such a security breach could impair our ability to operate our business, including our ability to provide support services to our customers.
We believe that there is a trend for large and mid-sized enterprises to migrate their on-premise email systems to cloud-based offerings. If we fail to successfully develop,
market, broaden or enhance our solutions to continue to be attractive to existing customers currently using cloud-based email systems or by new prospects, our ability to grow or maintain our revenue
could be harmed, and our business could suffer.
We derive a substantial portion of our revenue from our solutions that protect and archive data in our customers'
on-premise email systems and expect to continue to do so for the foreseeable future. We currently derive a portion of our revenue from customers using cloud-based email systems
such as Google's Google Apps and Microsoft's Office 365, both of which include varying degrees of threat protection and governance services as part of their offering. A significant market shift from
on-premise email systems toward such cloud-based email systems could decrease demand for our solutions because customers who move to cloud-based email systems may no longer value our solutions; if our
current or prospective customers who utilize cloud-based email systems fail to find value in our solutions, our business could be adversely affected.
Historically, our solutions have been used primarily for email, and any decrease in the use of email systems by large and mid-sized enterprises over time, or the failure of
our newly developed solutions for emerging methods of communication and collaboration to gain acceptance could harm our business.
Historically, our customers have primarily used our solutions to protect and archive data in their corporate email systems. If the use
of email decreases, demand for our solutions would decrease and we may fail to diversify our revenue base by increasing demand for our other technology solutions.
In
addition, messaging and collaboration technologies are evolving rapidly. For instance, the widespread adoption and use of mobile devices, unmanaged Internet-based collaboration and
file sharing applications and social networking sites have caused valuable and sensitive data to proliferate well beyond traditional corporate email systems, resulting in new and increasing security
risks. We are devoting resources to continue developing and marketing our solutions for these emerging methods of communication and collaboration. However, our customers may not perceive the need to
deploy our solutions intended to address these emerging areas. If we are unable to successfully develop, market, broaden or enhance our solutions to address the wider range of threats caused by the
proliferation of new technologies and methods of communication, demand for our existing solutions would decrease, and our business would be harmed.

Table of Contents
If functionality similar to that offered by our solutions is incorporated into our competitors' networking products, potential or existing customers may decide against
adding our solutions to their network, which would have an adverse effect on our business.
Some large, well-established providers of networking equipment, such as Cisco and Juniper Networks, Inc. currently
offer, and may continue to introduce, network security features that compete with our solutions, either in stand-alone security products or as additional features in their network infrastructure
products. The inclusion of, or the announcement of an intent to include, functionality perceived to be similar to that offered by our solutions in networking products that are already generally
accepted as necessary components of customers' network architecture may have an adverse effect on our ability to market and sell our solutions. Furthermore, even if the functionality offered by
network infrastructure providers is more limited than that offered by our solutions, a significant number of our customers may elect to accept such limited functionality in lieu of adding appliances
or software from an additional vendor such as us. Many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep
relationships with other providers of networking products, which may make them reluctant to add new third-party components to their networks.
Our solutions collect, filter and archive customer data which may contain personal information, which raises privacy concerns and could result in us having liability or
inhibit sales of our solutions.
Many federal, state and foreign government bodies and agencies have adopted or are considering adopting laws and regulations regarding
the collection, use, and disclosure of personal information. Because many of the features of our solutions use, store, and report on customer data which may contain personal information from our
customers, any inability to adequately
address privacy concerns, or comply with applicable privacy laws, regulations and policies could, even if unfounded, result in liability to us, damage to our reputation, loss of sales, and harm to our
business. Furthermore, the costs of compliance with, and other burdens imposed by, such laws, regulations and policies that are applicable to the businesses of our customers may limit the use and
adoption of our solutions and reduce overall demand for them. Privacy concerns, whether or not valid, may inhibit market adoption of our solutions. For example, in the United States regulations such
as the Gramm-Leach-Bliley Act (GLBA), which protects and restricts the use of consumer credit and financial information, and the Health Insurance Portability and Accountability Act of 1996 (HIPAA),
which regulates the use and disclosure of personal health information, impose significant security and data protection requirements and obligations on businesses that may affect the use and adoption
of our solutions. The European Union has also adopted a data privacy directive that requires member states to impose restrictions on the collection and use of personal data that, in some respects, are
more stringent, and impose more significant burdens on subject businesses, than current privacy standards in the United States.
Any
failure or perceived failure to comply with laws and regulations may result in proceedings or actions against us by government entities or others, or could cause us to lose users and
customers, which could potentially have an adverse effect on our business.
If we do not effectively expand and train our sales force, we may be unable to add new customers or increase sales to our existing customers and our business will be harmed.
We continue to be substantially dependent on our sales force to obtain new customers and to sell additional solutions to our existing
customers. We believe that there is significant competition for sales personnel with the skills and technical knowledge that we require. Our ability to achieve significant revenue growth will depend,
in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel to support our growth. New hires require significant training and may take significant time
before they achieve full productivity. Our recent hires and planned hires may not become as productive as we expect, and we may be unable to hire or retain sufficient numbers of
16
Table of Contents
qualified
individuals in the markets where we do business or plan to do business. If we are unable to hire and train sufficient numbers of effective sales personnel, or the sales personnel are not
successful in obtaining new customers or increasing sales to our existing customer base, our business will be harmed.
Our sales cycle is long and unpredictable, and our sales efforts require considerable time and expense. As a result, our results are difficult to predict and may vary
substantially from quarter to quarter, which may cause our operating results to fluctuate.
We sell our security and compliance offerings primarily to enterprise IT departments that are managing a growing set of user and
compliance demands, which has increased the complexity of customer requirements to be met and confirmed in the sales cycle. Additionally, we have found that increasingly security, legal and compliance
departments are involved in testing, evaluating and finally approving purchases, which has also made the sales cycle longer and less predictable. We may not be able to accurately predict or forecast
the timing of sales, which makes our future revenue difficult to predict and could cause our results to vary significantly. In addition, we might devote substantial time and effort to a particular
unsuccessful sales effort, and as a result we could lose other sales opportunities or incur expenses that are not offset by an increase in revenue, which could harm our business.
Because our long-term success depends, in part, on our ability to expand the sales of our platform to our customers located outside of the United States, our
business will be increasingly susceptible to risks associated with international operations.
One key element of our growth strategy is to develop a worldwide customer base and expand our operations worldwide. We have added
employees, offices and customers internationally, particularly in Europe and Asia. Operating in international markets requires significant resources and management attention and will subject us to
regulatory, economic, political and competitive risks and competition that are different from those in the United States. Because of our limited experience with international operations, we cannot
assure you that our international expansion efforts will be successful or that expected returns on such investments will be achieved in the future.
In
addition, our international operations may fail to succeed due to other risks inherent in operating businesses internationally, including:
•
our lack of familiarity with commercial and social norms and customs in other countries which may adversely affect our

Our
failure to manage any of these risks successfully could harm our existing and future international operations and seriously impair our overall business.
If the market for our delivery model and cloud computing services develops more slowly than we expect, our business could be harmed.
Our success will depend to a substantial extent on the willingness of enterprises, large and small, to increase their use of cloud
computing services. The market for messaging security and data compliance solutions delivered as a service in particular is at an early stage relative to on-premise solutions, and these
applications may not achieve and sustain high levels of demand and market acceptance. Many enterprises have invested substantial personnel and financial resources to integrate traditional enterprise
software or hardware appliances for these applications into their businesses or may be reluctant or unwilling to use cloud computing services because they have concerns regarding the risks associated
with reliability and security, among other things, of this delivery model, or its ability to help them comply with applicable laws and regulations. If enterprises do not perceive the benefits of this
delivery model, then the market for our services may develop more slowly than we expect, which would adversely affect our business and operating results.
If we are unable to enhance our existing solutions and develop new solutions, our growth will be harmed and we may not be able to achieve profitability.
Our ability to attract new customers and increase revenue from existing customers will depend in large part on our ability to enhance
and improve our existing solutions and to introduce new solutions. The success of any enhancement or new solution depends on several factors, including the timely completion, introduction and market
acceptance of the enhancement or solution. Any new enhancement or solution we develop or acquire may not be introduced in a timely or cost-effective manner and may not achieve the broad
market acceptance necessary to generate significant revenue. If we are unable to successfully develop or acquire new solutions or enhance our existing solutions to meet customer requirements, we may
not grow as expected and we may not achieve profitability.
We
cannot be certain that our development activities will be successful or that we will not incur delays or cost overruns. Furthermore, we may not have sufficient financial resources to
identify and develop new technologies and bring enhancements or new solutions to market in a timely and cost effective manner. New technologies and enhancements could be delayed or cost more than we
expect, and we cannot ensure that any of these solutions will be commercially successful if and when they are introduced.

If we are unable to cost-effectively scale or adapt our existing architecture to accommodate increased traffic, technological advances or changing customer
requirements, our operating results could be harmed.
As our customer base grows, the number of users accessing our solutions over the Internet will correspondingly increase. Increased
traffic could result in slow access speeds and response times. Since our customer agreements often include service availability commitments, slow speeds or our failure to accommodate increased traffic
could result in breaches of our service level agreements or obligate us to issue service credits. In addition, the market for our solutions is characterized by rapid technological advances and changes
in customer requirements. In order to accommodate increased traffic and respond to technological advances and evolving customer requirements, we expect that we will be required to make future
investments in our network architecture. If we do not implement future upgrades to our network architecture cost-effectively, or if we experience prolonged delays or unforeseen
difficulties in connection with upgrading our network architecture, our service quality may suffer and our operating results could be harmed.
Our quarterly operating results are likely to vary significantly and be unpredictable, which could cause the trading price of our stock to decline.
Our operating results have historically varied from period to period, and we expect that they will continue to do so as a result of a
number of factors, many of which are outside of our control and may be difficult to predict, including:
•
the level of demand for our solutions and the level of perceived urgency regarding security threats and compliance
requirements;
•
the timing of new subscriptions and renewals of existing subscriptions;
•
the mix of solutions sold;
•
the extent to which customers subscribe for additional solutions or increase the number of users;
•
customer budgeting cycles and seasonal buying patterns;
•
the extent to which we bring on new distributors;
•
any changes in the competitive landscape of our industry, including consolidation among our competitors, customers,
partners or resellers;
•
deferral of orders in anticipation of new solutions or enhancements announced by us;
•
price competition;
•
changes in renewal rates and terms in any quarter;
•
any disruption in our sales channels or termination of our relationship with important channel partners;
•
general economic conditions, both domestically and in our foreign markets;
•
insolvency or credit difficulties confronting our customers, affecting their ability to purchase or pay for our solutions;
or
•
future accounting pronouncements or changes in our accounting policies.
Any
one of the factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our quarterly financial and other operating
results, including fluctuations in our key metrics. This variability and unpredictability could result in our failing to meet the expectations of securities analysts or investors for any period. If we
fail to meet or exceed such expectations for these or any other reasons, the market price of our shares could fall substantially and
19
Table of Contents
we
could face costly lawsuits, including securities class action suits. In addition, a significant percentage of our operating expenses are fixed in nature and based on forecasted revenue and cash
flow trends. Accordingly, in the event of revenue shortfalls, we are generally unable to mitigate the negative impact on margins or other operating results in the short term.
If we fail to manage our sales and distribution channels effectively or if our partners choose not to market and sell our solutions to their customers, our operating results
could be adversely affected.
We have derived and anticipate that in the future we will continue to derive a substantial portion of the sales of our solutions
through channel partners. In order to scale our channel program to support growth in our business, it is important that we continue to help our partners enhance their ability to independently sell and
deploy our solutions. We may be unable to continue to successfully expand and improve the effectiveness of our channel sales program.
Our
agreements with our channel partners are generally non-exclusive and some of our channel partners have entered, and may continue to enter, into strategic relationships
with our competitors or are competitors themselves. Further, many of our channel partners have multiple strategic relationships and they may not regard us as significant for their businesses. Our
channel partners may terminate their respective relationships with us with limited or no notice and with limited or no penalty, pursue other partnerships or relationships, or attempt to develop or
acquire products or services that compete with our solutions. Our partners also may impair our ability to enter into other desirable strategic relationships. If our channel partners do not effectively
market and sell our
solutions, if they choose to place greater emphasis on products of their own or those offered by our competitors, or if they fail to meet the needs of our customers, our ability to grow our business
and sell our solutions may be adversely affected. Similarly, the loss of a substantial number of our channel partners, and our possible inability to replace them, the failure to recruit additional
channel partners, any reduction or delay in their sales of our solutions, or any conflicts between channel sales and our direct sales and marketing activities could materially and adversely affect our
results of operations.
Because we recognize revenue from subscriptions over the term of the relevant service period, decreases or increases in sales are not immediately reflected in full in our
operating results.
We recognize revenue from subscriptions over the term of the relevant service period, which typically range from one to three years,
with some up to five years. As a result, most of our quarterly revenue from subscriptions results from agreements entered into during previous quarters. Consequently, a shortfall in demand for our
solutions in any quarter may not significantly reduce our subscription revenue for that quarter, but could negatively affect subscription revenue in future quarters. We may be unable to adjust our
cost structure to compensate for this potential shortfall in subscription revenue. Accordingly, the effect of significant downturns in sales of subscriptions may not be fully reflected in our results
of operations until future periods. Our subscription model also makes it difficult for us to rapidly increase our subscription revenue through additional sales in any period, as subscription revenue
must be recognized over the term of the contract.
Interruptions or delays in services provided by third parties could impair the delivery of our service and harm our business.
We currently serve our customers from third-party data center hosting facilities located in the United States, Canada and Europe. We
also rely on bandwidth providers, Internet service providers, and mobile networks to deliver our solutions. Any damage to, or failure of, the systems of our third-party providers could result in
interruptions to our service. If for any reason our arrangement with one or more of our data centers is terminated we could experience additional expense in arranging for new facilities and support.
Our data center facilities providers have no obligations to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew our agreements with the
20
Table of Contents
facilities
providers on commercially reasonable terms or if in the future we add additional data center facility providers, we may experience costs or downtime in connection with the transfer to, or
the addition of, new data center facilities. In addition, the failure of our data centers to meet our capacity requirements could result in interruptions in the availability of our solutions, impair
the functionality of our solutions or impede our ability to scale our operations. As we continue to add data centers, restructure our data management plans, and increase capacity in existing and
future data centers, we
may move or transfer our data and our customers' data. Despite precautions taken during such processes and procedures, any unsuccessful data transfers may impair the delivery of our service, and we
may experience costs or downtime in connection with the transfer of data to other facilities.
We
also depend on access to the Internet through third-party bandwidth providers to operate our business. If we lose the services of one or more of our bandwidth providers, or if these
providers experience outages, for any reason, we could experience disruption in delivering our solutions or we could be required to retain the services of a replacement bandwidth provider. Our
business also depends on our customers having high-speed access to the Internet. Any Internet outages or delays could adversely affect our ability to provide our solutions to our
customers.
Our
operations also rely heavily on the availability of electricity, which also comes from third-party providers. If we or the third-party data center facilities that we use to deliver
our services were to experience a major power outage or if the cost of electricity were to increase significantly, our operations and financial results could be harmed. If we or our third-party data
centers were to experience a major power outage, we or they would have to rely on back-up generators, which might not work properly or might not provide an adequate supply during a major
power outage. Such a power outage could result in a significant disruption of our business.
The
occurrence of an extended interruption of ours or third-party services for any reason could result in lengthy interruptions in our services or in the delivery of customers' email and
require us to provide service credits, refunds, indemnification payments or other payments to our customers, and could also result in the loss of customers.
Any failure to offer high-quality technical support services may adversely affect our relationships with our customers and harm our financial results.
Once our solutions are deployed, our customers depend on our support organization to resolve any technical issues relating to our
solutions. In addition, our sales process is highly dependent on our solutions and business reputation and on strong recommendations from our existing customers. Any failure to maintain
high-quality technical support, or a market perception that we do not maintain high-quality support, could harm our reputation, adversely affect our ability to sell our
solutions to existing and prospective customers, and harm our business, operating results and financial condition.
We
offer technical support services with many of our solutions. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support
services. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. Increased customer demand for these services, without
corresponding revenue, could increase costs and adversely affect our operating results.
We
have outsourced a substantial portion of our worldwide customer support functions to third-party service providers. If these companies experience financial difficulties, do not
maintain sufficiently skilled workers and resources to satisfy our contracts, or otherwise fail to perform at a sufficient level, the level of support services to our customers may be significantly
disrupted, which could materially harm our reputation and our relationships with these customers.

Table of Contents
If we fail to develop or protect our brand, our business may be harmed.
We believe that developing and maintaining awareness and integrity of our company and our brand are important to achieving widespread
acceptance of our existing and future offerings and are important elements in attracting new customers. We believe that the importance of brand recognition will increase as competition in our market
further intensifies. Successful promotion of our brand will depend on the effectiveness of our marketing efforts and on our ability to provide reliable and useful solutions at competitive prices. We
plan to continue investing substantial resources to promote our brand, both domestically and internationally, but there is no guarantee that our brand development strategies will enhance the
recognition of our brand. Some of our existing and potential competitors have well-established brands with greater recognition than we have. If our efforts to promote and maintain our
brand are not successful, our operating results and our ability to attract and retain customers may be adversely affected. In addition, even if our brand recognition and loyalty increases, this may
not result in increased use of our solutions or higher revenue.
In
addition, independent industry analysts often provide reviews of our solutions, as well as those of our competitors, and perception of our solutions in the marketplace may be
significantly influenced by these reviews. We have no control over what these industry analysts report, and because industry
analysts may influence current and potential customers, our brand could be harmed if they do not provide a positive review of our solutions or view us as a market leader.
The steps we have taken to protect our intellectual property rights may not be adequate.
We rely on a combination of contractual rights, trademarks, trade secrets, patents and copyrights to establish and protect our
intellectual property rights. These offer only limited protection, however, and the steps we have taken to protect our proprietary technology may not deter its misuse, theft or misappropriation. Any
of our patents, copyrights, trademarks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Competitors may independently
develop technologies or products that are substantially equivalent or superior to our solutions or that inappropriately incorporate our proprietary technology into their products. Competitors may hire
our former employees who may misappropriate our proprietary technology or misuse our confidential information. Although we rely in part upon confidentiality agreements with our employees, consultants
and other third parties to protect our trade secrets and other confidential information, those agreements may not effectively prevent disclosure of trade secrets and other confidential information and
may not provide an adequate remedy in the event of misappropriation of trade secrets or unauthorized disclosure of confidential information. In addition, others may independently discover our trade
secrets and confidential information, and in such cases we could not assert any trade secret rights against such parties.
We
might be required to spend significant resources to monitor and protect our intellectual property rights. We may initiate claims or litigation against third parties for infringement
of our intellectual property rights or misappropriation of our trade secrets, or to establish the validity of our intellectual property rights. Any litigation, whether or not it is resolved in our
favor, could result in significant expense to us and divert the efforts of our technical and management personnel, which may adversely affect our business, operating results and financial condition.
Certain jurisdictions may not provide adequate legal infrastructure for effective protection of our intellectual property rights. Changing legal interpretations of liability for unauthorized use of
our solutions or lessened sensitivity by corporate, government or institutional users to refraining from intellectual property piracy or other infringements of intellectual property could also harm
our business.
Our
issued patents may not provide us with any competitive advantages or may be challenged by third parties, and our patent applications may never be granted at all. It is possible that
innovations for which we seek patent protection may not be protectable. Additionally, the process of obtaining patent
22
Table of Contents
protection
is expensive and time consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. Given the cost, effort, risks
and downside of obtaining patent protection, including the requirement to ultimately disclose the
invention to the public, we may not choose to seek patent protection for certain innovations. However, such patent protection could later prove to be important to our business. Even if issued, there
can be no assurance that any patents will have the coverage originally sought or adequately protect our intellectual property, as the legal standards relating to the validity, enforceability and scope
of protection of patent and other intellectual property rights are uncertain. Any patents that are issued may be invalidated or otherwise limited, or may lapse or may be abandoned, enabling other
companies to better develop products that compete with our solutions, which could adversely affect our competitive business position, business prospects and financial condition.
We
cannot assure you that the measures we have taken to protect our intellectual property will adequately protect us, and any failure to protect our intellectual property could harm our
business.
Third parties claiming that we infringe their intellectual property rights could cause us to incur significant legal expenses and prevent us from selling our solutions.
Companies in the software and technology industries, including some of our current and potential competitors, own large numbers of
patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement, misappropriation or other violations of intellectual property rights. In
addition, many of these companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them.
The litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our potential patents may provide little or no deterrence. We
have received, and may in the future receive, notices that claim we have infringed, misappropriated or otherwise violated other parties' intellectual property rights. To the extent we gain greater
visibility, we face a higher risk of being the subject of intellectual property infringement claims, which is not uncommon with respect to software technologies in general and information security
technology in particular. There may be third-party intellectual property rights, including issued or pending patents that cover significant aspects of our technologies or business methods. Any
intellectual property claims, with or without merit, could be very time consuming, could be expensive to settle or litigate and could divert our management's attention and other resources. These
claims could also subject us to significant liability for damages, potentially including treble damages if we are found to have willfully infringed patents or copyrights. These claims could also
result in our having to stop using technology found to be in violation of a third party's rights. We might be required to seek a license for the intellectual property, which may not be available on
reasonable terms or at all. Even if a license were available, we could be required to pay significant royalties, which would increase our operating expenses. As a result, we may be required to develop
alternative non-infringing technology, which could require significant effort and expense. If we cannot license or develop technology for any infringing aspect of our business, we would be
forced to limit or stop sales of one or more of our solutions or features of our solutions and may be unable to compete effectively. Any of these results would harm our business, operating results and
financial condition.
In
addition, our agreements with customers and channel partners include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of
claims of
intellectual property infringement and, in some cases, for damages caused by us to property or persons. Large indemnity payments could harm our business, operating results and financial condition.
23
Table of Contents
We rely on technology and intellectual property licensed from other parties, the failure or loss of which could increase our costs and delay or prevent the delivery of our
solutions.
We utilize various types of software and other technology, as well as intellectual property rights, licensed from unaffiliated third
parties in order to provide certain elements of our solutions. Any errors or defects in any third-party technology could result in errors in our solutions that could harm our business. In addition,
licensed technology and intellectual property rights may not continue to be available on commercially reasonable terms, or at all. While we believe that there are currently adequate replacements for
the third-party technology we use, any loss of the right to use any of this technology on commercially reasonable terms, or at all, could result in delays in producing or delivering our solutions
until equivalent technology is identified and integrated, which delays could harm our business. In this situation we would be required to either redesign our solutions to function with software
available from other parties or to develop these components ourselves, which would result in increased costs. Furthermore, we might be forced to limit the features available in our current or future
solutions. If we fail to maintain or renegotiate any of these technology or intellectual property licenses, we could face significant delays and diversion of resources in attempting to develop similar
or replacement technology, or to license and integrate a functional equivalent of the technology.
Some of our solutions contain "open source" software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our
business.
Some of our solutions are distributed with software licensed by its authors or other third parties under so-called "open
source" licenses, which may include, by way of example, the GNU General Public License, or GPL, and the Apache License. Some of these licenses contain requirements that we make available source
code for modifications or derivative works we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license
or other license granting third parties certain rights of further use. By the terms of certain open source licenses, we could be required to release the source code of our proprietary software, and to
make our proprietary software available under open source licenses, if we combine our proprietary software with open source software in a certain manner. In the event that portions of our proprietary
software are determined to be subject to an open source license, we could be required to publicly release the affected portions of our source code, re-engineer all or a portion of our
technologies, or otherwise be limited in the licensing of our technologies, each of which could reduce or eliminate the value of our technologies and
solutions. In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third party commercial software, as open source licensors generally
do not provide warranties or controls on the origin of the software. We have established processes to help alleviate these risks, including a review process for screening requests from our development
organizations for the use of open source software, but we cannot be sure that all open source software is submitted for approval prior to use in our solutions, that our programmers have not
incorporated open source software into our proprietary solutions and technologies or that they will not do so in the future. In addition, many of the risks associated with usage of open source
software cannot be eliminated, and could, if not properly addressed, negatively affect our business.
Governmental regulations affecting the export of certain of our solutions could negatively affect our business.
Our products are subject to U.S. export controls, and we incorporate encryption technology into certain of our products. These
encryption products and the underlying technology may be exported outside the United States only with the required export authorizations, including by license, a license exception or other appropriate
government authorizations, including the filing of an encryption registration. Governmental regulation of encryption technology and regulation of imports or exports, or our failure to obtain required
import or export approval for our products, could harm our international sales and adversely affect our revenue.
24
Table of Contents
We
determined that subsequent to August 2008, we may have shipped a particular hardware appliance model to a limited number of international customers that, prior to shipment, may have
required either a one-time product review or application for an encryption registration number in lieu of such product review. We are making a voluntary submission to the U.S. Commerce
Department's Bureau of Industry and Security (BIS) to report this potential violation.
In
addition, the U.S. government also prohibits U.S. companies from doing business with customers in certain restricted countries. As part of a pre-IPO due diligence review,
we discovered a potential export violation involving the provision of web-based, email communication services to end-users located in Iran through our Everyone.net service,
which we acquired in October 2009. Neither of these suspected end-users appears to have been a current customer of these web-based, email communication services since late 2010
or early 2011. Although we had ceased providing the services, we are making a voluntary submission to the U.S. Department of Treasury's Office of Foreign Assets Control (OFAC) to report this potential
violation. Our investigation of these matters is still ongoing, and it is possible that we may discover additional violations.
Failure
to comply with such regulations and these recent voluntary submissions could result in penalties, costs, and restrictions on export privileges, which could also harm our
operating results.
We have experienced rapid growth in recent periods. If we fail to manage such growth and our future growth effectively, we may be unable to execute our business plan,
maintain high levels of service or adequately address competitive challenges.
We have experienced significant growth in recent periods. For example, we grew from 158 employees on December 31, 2007 to 348 on
September 30, 2011. This growth has placed, and any future growth may place, a significant strain on our management and operational infrastructure, including our hosting operations. Our success
will depend, in part, on our ability to manage these changes effectively. We will need to continue to improve our operational, financial and management controls and our reporting systems and
procedures. Failure to effectively manage growth could result in declines in service quality or customer satisfaction, increases in costs, difficulties in introducing new features or other operational
difficulties. Any failure to effectively manage growth could adversely impact our business and reputation.
The forecasts of market growth included in this prospectus may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, we cannot
assure you our business will grow at similar rates, if at all.
Growth forecasts are subject to significant uncertainty and are based on assumptions and estimates which may not prove to be accurate.
Forecasts relating to the expected growth in the security and other markets may prove to be inaccurate. Even if these markets experience the forecasted growth, we may not grow our business at similar
rates, or at all. Our growth is subject to many factors, including our success in implementing our business strategy, which is subject to many risks and uncertainties. Accordingly, the forecasts of
market growth included in this prospectus should not be taken as indicative of our future growth.
We have and may further expand through acquisitions of, or investments in, other companies, which may divert our management's attention, dilute our stockholders and consume
corporate resources that otherwise would be necessary to sustain and grow our business.
Our business strategy may, from time to time, include acquiring complementary products, technologies or businesses. We also may enter
into relationships with other businesses in order to expand our solutions, which could involve preferred or exclusive licenses, additional channels of distribution, or investments by or between the
two parties. Negotiating these transactions can be time consuming, difficult and expensive, and our ability to close these transactions may be subject to third-party approvals, such as
25
Table of Contents
government
regulation, which are beyond our control. Consequently, we can make no assurance that these transactions, once undertaken and announced, will close.
These
kinds of transactions may result in unforeseen operating difficulties and expenditures. In particular, we may encounter difficulties assimilating or integrating the businesses,
technologies, products, personnel or operations of acquired companies, particularly if the key personnel of the acquired business choose not to work for us, and we may have difficulty retaining the
customers of any acquired business. Acquisitions may also disrupt our ongoing business, divert our resources and require significant management attention that would otherwise be available for
development of our business. Any acquisition or investment could expose us to unknown liabilities. In addition, as of September 30, 2011, we had $20.4 million in goodwill and intangible
assets recorded on our consolidated balance sheet. We may in the future need to incur charges with respect to the write-down or impairment of goodwill or intangible assets, which could
adversely affect our operating results. Moreover, we cannot assure you that the anticipated benefits of any acquisition or investment would be realized or that we would not be exposed to unknown
liabilities. In connection with these types of transactions, we may issue additional equity securities that would dilute our stockholders, use cash that we may need in the future to operate our
business, incur debt on terms unfavorable to us or that we are unable to repay, incur large charges or substantial liabilities, encounter difficulties integrating diverse business cultures, and become
subject to adverse tax consequences, substantial depreciation or deferred compensation charges. These challenges related to acquisitions or investments could adversely affect our business, operating
results and financial condition.
If we are unable to attract and retain qualified employees, lose key personnel, fail to integrate replacement personnel successfully, or fail to manage our employee base
effectively, we may be unable to develop new and enhanced solutions, effectively manage or expand our business, or increase our revenue.
Our future success depends upon our ability to recruit and retain key management, technical, sales, marketing, finance, and other
critical personnel. Despite the economic
downturn, competition for qualified management, technical and other personnel is intense, and we may not be successful in attracting and retaining such personnel. If we fail to attract and retain
qualified employees, our ability to grow our business could be harmed. Our officers and other key personnel are employees-at-will, and we cannot assure you that we will be able
to retain them. Competition for people with the specific skills that we require is significant. In order to attract and retain personnel in a competitive marketplace, we believe that we must provide a
competitive compensation package, including cash and equity-based compensation. Volatility in our stock price may from time to time adversely affect our ability to recruit or retain employees. If we
are unable to hire and retain qualified employees, or conversely, if we fail to manage employee performance or reduce staffing levels when required by market conditions, our business and operating
results could be adversely affected.
In
addition, hiring, training, and successfully integrating replacement personnel could be time consuming, may cause additional disruptions to our operations, and may be unsuccessful,
which could negatively impact future revenue.
Changes in laws and/or regulations related to the Internet or changes in the Internet infrastructure itself may diminish the demand for our solutions, and could have a
negative impact on our business.
The future success of our business depends upon the continued use of the Internet as a primary medium for commerce, communication and
business applications. Federal, state or foreign government bodies or agencies have in the past adopted, and may in the future adopt, laws or regulations affecting data privacy and the use of the
Internet as a commercial medium. Changes in these laws or regulations could require us to modify our solutions in order to comply with these changes. In addition, government agencies or private
organizations may begin to impose taxes, fees or other charges for accessing the Internet or commerce conducted via the Internet. These laws or charges could limit the
26
Table of Contents
growth
of Internet-related commerce or communications generally, result in a decline in the use of the Internet and the viability of Internet-based applications such as ours and reduce the demand for
our solutions.
The
legal and regulatory framework also drives demand for our solutions. Our customers are subject to laws, regulations and internal policies that mandate how they process, handle,
store, use and transmit a variety of sensitive data and communications. These laws and regulations are subject to revision, change and interpretation at any time, and any such change could either help
or hurt the demand for our solutions. We cannot be sure that the legal and regulatory framework in any given jurisdiction will be favorable to our business or that we will be able to sustain or grow
our business if there are any adverse changes to these laws and regulations.
If we are required to collect sales and use taxes on the solutions we sell, we may be subject to liability for past sales and our future sales may decrease.
State and local taxing jurisdictions have differing rules and regulations governing sales and use taxes, and these rules and
regulations are subject to varying interpretations that may change over time. In particular, the applicability of sales taxes to our subscription services in various jurisdictions is unclear. We have
recorded sales tax liabilities of $0.1 million on our consolidated balance sheet as of September 30, 2011 in respect of sales and use tax liabilities in various states and local
jurisdictions. It is possible that we could face sales tax audits and that our liability for these taxes could exceed our estimates as state tax authorities could still assert that we are obligated to
collect additional amounts as taxes from our customers and remit those taxes to those authorities. We could also be subject to audits with respect to state and international jurisdictions for which we
have not accrued tax liabilities. A successful assertion that we should be collecting additional sales or other taxes on our services in jurisdictions where we have not historically done so and do not
accrue for sales taxes could result in substantial tax liabilities for past sales, discourage customers from purchasing our application or otherwise harm our business and operating results.
Adverse conditions in the national and global economies and financial markets may adversely affect our business and financial results.
Our financial performance depends, in part, on the state of the economy, which deteriorated in the recent broad recession, and which
may deteriorate in the future. Challenging economic conditions worldwide have from time to time contributed, and may continue to contribute, to slowdowns in the information technology industry,
resulting in reduced demand for our solutions as a result of continued constraints on IT-related capital spending by our customers and increased price competition for our solutions.
Moreover, we target some of our solutions to the financial services industry and therefore if there is consolidation in that industry, or layoffs, or lack of funding for IT purchases, our business may
suffer. If unfavorable economic conditions continue or worsen, our business, financial condition and operating results could be materially and adversely affected.
Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events, and to interruption by manmade problems such as terrorism.
Natural disasters or other catastrophic events may cause damage or disruption to our operations, international commerce and the global
economy, and thus could have a strong negative effect on us. We have significant operations in the Silicon Valley area of Northern California, a region known for seismic activity. A major earthquake
or other natural disaster, fire, act of terrorism or other catastrophic event that results in the destruction or disruption of any of our critical business operations or information technology systems
could severely affect our ability to conduct normal business operations and, as a result, our future operating results could be harmed. These negative events could make it difficult or impossible for
us to deliver our services to our customers, and could decrease demand for our services. Because we do not carry earthquake insurance for direct quake-related losses,
27
Table of Contents
and
significant recovery time could be required to resume operations, our financial condition and operating results could be materially adversely affected in the event of a major earthquake or
catastrophic event.
A portion of our revenue is generated by sales to government entities, which are subject to a number of challenges and risks.
Sales to U.S. and foreign federal, state and local governmental agency customers have accounted for a portion of our revenue in past
periods, and we may in the future increase sales to government entities. Sales into government entities are subject to a number of risks. Selling to government entities can be highly competitive,
expensive and time consuming, often requiring significant upfront time and expense without any assurance that we will win a sale. We have invested in the creation of a cloud offering certified under
the Federal Information Security Management Act (FISMA) for government usage but we cannot be sure that we will continue to sustain or renew this certification, that the government will continue to
mandate such certification or that other government agencies or entities will use this cloud offering. Government demand and payment for our solutions may be impacted by public sector budgetary cycles
and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our solutions. Government entities may have contractual or other legal rights to terminate
contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our future results of operations. For example, if the distributor
receives a significant portion of its revenue from sales to such governmental entity, the financial health of the distributor could be substantially harmed, which could negatively affect our future
sales to such distributor. Governments routinely investigate and audit government contractors' administrative processes, and any unfavorable audit could result in the government refusing to continue
buying our solutions, a reduction of revenue or fines or civil or criminal liability if the audit uncovers improper or illegal activities. Any such penalties could adversely impact our results of
operations in a material way.
If we fail to maintain an effective system of internal controls, our ability to produce timely and accurate financial statements or comply with applicable regulations could
be impaired.
As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, and the rules and regulations of the NASDAQ Global Market. We expect that the requirements of these rules and regulations will continue to increase our legal, accounting and
financial compliance costs, make some activities more difficult, time consuming and costly, and place significant strain on our personnel, systems and resources.
The
Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to
develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the Securities and Exchange
Commission, or the SEC, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in reports under the
Exchange Act is accumulated and communicated to our principal executive and financial officers.
Our
current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further, weaknesses in our internal controls may be
discovered in the future. Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm our operating results or cause us to
fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal controls also could
adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over
financial reporting that we are required
28
Table of Contents
to
include in our periodic reports we will file with the SEC under Section 404 of the Sarbanes-Oxley Act. Ineffective disclosure controls and procedures and internal control over financial
reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock.
In
order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will
continue to expend, significant resources, including accounting-related costs, and provide significant management oversight. Any failure to maintain the adequacy of our internal controls, or
consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. In the event that
we are not able to demonstrate compliance with Section 404 of the Sarbanes-Oxley Act that our internal controls are perceived as
inadequate or that we are unable to produce timely or accurate financial statements, investors may lose confidence in our operating results and our stock price could decline. In addition, if we are
unable to continue to meet these requirements, we may not be able to remain listed on The NASDAQ Global Market.
We
are not currently required to comply with the SEC rules that implement Sections 302 and 404 of the Sarbanes-Oxley Act, and are therefore not required to make a formal
assessment of the effectiveness of our internal controls over financial reporting for that purpose. Upon becoming a public company, we will be required to comply with these rules, which will require
management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal control over financial reporting.
Though we will be required to disclose changes made in our internal control and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal control
over financial reporting pursuant to Section 404 until the year following our first annual report required to be filed with the SEC. To comply with the requirements of being a public company,
we may need to undertake various actions, such as implementing new internal controls and procedures and hiring accounting or internal audit staff.
Our
independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until the year following our
first annual report required to be filed with the SEC. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the
level at which our controls are documented, designed or operating. Our remediation efforts may not enable us to avoid a material weakness in the future.
We will incur significantly increased costs and devote substantial management time as a result of operating as a public company.
As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. For
example, we will be required to comply with the requirements of the Sarbanes-Oxley Act and the Dodd Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently
implemented by the SEC, and the NASDAQ Global Market, our stock exchange, including the establishment and maintenance of effective disclosure and financial controls and changes in corporate governance
practices. We expect that compliance with these requirements will increase our legal and financial compliance costs and will make some activities more time consuming and costly. In addition, we expect
that our management and other personnel will need to divert attention from operational and other business matters to devote substantial time to these public company requirements. In particular, we
expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act. In that regard, we
currently do not have an internal audit function, and we will need to hire additional accounting and financial staff with appropriate public company experience and
29
Table of Contents
technical
accounting knowledge. We cannot predict or estimate the amount of additional costs we may incur as a result of becoming a public company or the timing of such costs. We also expect that
operating as a public company will make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and
coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified people to serve on our board of
directors, our board committees or as executive officers.
Risks Related to Our Common Stock
Purchasers in this offering will experience immediate and substantial dilution in the book value of their investment.
The initial public offering price of our common stock will be substantially higher than the net tangible book value per share of our
outstanding common stock immediately after this offering. Therefore, if you purchase our common stock in this offering, you will incur immediate
dilution of $            in net tangible book value per share from the price you paid assuming we offer our shares at
$            , the mid-point of the range on the cover of this
prospectus. In addition, investors purchasing common stock in this offering will have contributed        % of the total consideration paid by our stockholders to purchase shares of common
stock, but will own        % of our outstanding common stock. Moreover, we issued options and a warrant in the past to acquire common stock at prices significantly below the initial public
offering price. As of September 30, 2011, there were 20,227,426 shares of our common stock issuable upon the exercise of stock options outstanding, with a weighted-average exercise price of
$1.73 per share. To the extent that these outstanding options are ultimately exercised, you will incur further dilution.
An active, liquid and orderly trading market for our common stock may not develop, the price of our stock may be volatile, and you could lose all or part of your investment.
Prior to this offering, there has been no public market for our common stock. We cannot predict the extent to which investor interest
in us will lead to the development of an active trading market in our common stock or how liquid that market might become. An active public market for our common stock may not develop or be sustained
after the offering. If an active public market does not develop or is not sustained, it may be difficult for you to sell your shares of common stock at a price that is attractive to you, or at all.
The market price for shares of our common stock may decline below the initial public offering price, and you may not be able to resell your shares of common stock at or above the initial public
offering price. In addition, the trading price of our common stock following the offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors,
including but not limited to, those described in this "Risk Factors" section, performance by other companies in our industry and in the technology industry generally, and overall market conditions,
some of which are beyond our control. If the stock market in general experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our
business, financial condition or results of operations. Some companies that have had volatile market prices for their securities have had securities class actions filed against them. If a suit were
filed against us, regardless of its merits or outcome, it would likely result in substantial costs and divert management's attention and resources. This could have a material adverse effect on our
business, operating results and financial condition.
Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover attempt.
Our certificate of incorporation and bylaws contain provisions that could have the effect of rendering more difficult, delaying or
preventing an acquisition of our company deemed undesirable by our board of directors. These provisions could also reduce the price that investors might be willing to
30
Table of Contents
pay
in the future for shares of our common stock and result in the market price of our common stock being lower than it would be without these provisions. Our corporate governance documents include
provisions:
•
creating a classified board of directors whose members serve staggered three-year terms;
•
authorizing "blank check" preferred stock, which could be issued by our board without stockholder approval which may
contain voting, liquidation, dividend and other rights which are superior to our common stock;
•
limiting the liability of, and providing indemnification to, our directors and officers;
•
limiting the ability of our stockholders to call and bring business before special meetings by providing that any
stockholder action must be effected at a duly called meeting of the stockholders and not by a consent in writing, and providing that only our board of directors, the chairman of our board of
directors, our Chief Executive Officer or President may call a special meeting of the stockholders; and
•
requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for
nominations of candidates for election to our board of directors.
These
provisions, alone or together, could frustrate, delay or prevent hostile takeovers and changes in control or changes in our management.
As
a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders
holding more than 15% of our outstanding common stock from engaging in certain business combinations merging or combining with us without approval of the holders of a substantial majority of all of
our outstanding common stock.
Our directors, executive officers and principal stockholders will continue to have substantial control over us after this offering and could delay or prevent a change in
control or acquisition of us.
After this offering, our directors, executive officers and holders of more than 5% of our common stock, together with their affiliates,
will beneficially own, in the aggregate,        % of our outstanding common stock. As a result, these stockholders, acting together, would have the ability to control the outcome of matters
submitted to our stockholders for approval, including the election of directors and the approval of any merger or consolidation of our company or sale of all or substantially all of our assets. In
addition, these stockholders, acting together, would have the ability to control the management and affairs of our company through their ability to elect the members of our board of directors. The
interests of these stockholders may not always coincide with the interests of our other stockholders. For instance, these stockholders may cause us to enter into transactions or agreements that we
would not otherwise consider. In addition, this concentration of ownership might harm the market price of our common stock by:
•
delaying, deferring or preventing a change in control of us;
•
impeding a merger, consolidation, takeover or other business combination involving us; or
•
discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of us.
Most of our total outstanding shares may be sold into the market when the "lock-up" period ends. If there are substantial sales of shares of our common stock, the price of
our common stock could decline.
The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by our directors,
executive officers and significant stockholders, or if a large number of shares of our common stock becomes available for sale in the public market. After this offering, there will
be            
shares of our common stock issued and outstanding. This number of shares
31
Table of Contents
includes
the shares that we are selling in this offering, which may be resold in the public market immediately. The remaining            outstanding shares are currently restricted from resale as
a result of market standoff agreements. In addition, certain of these shares are also subject to lock-up agreements, as more fully described in "Underwriters." In each case, these shares
will become available to be sold 181 days after the date of this prospectus, subject to extension in some circumstances. Shares held by directors, executive officers and other affiliates will
be subject to volume limitations under Rule 144 under the Securities Act and various vesting agreements.
After
this offering, the holders of an aggregate of approximately 40,541,990 shares of our common stock outstanding will have rights, subject to some conditions, to require us to file
registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders. All of these shares are subject to market
standoff and/or lock-up agreements restricting their sale for 180 days after the date of this prospectus subject to extension in some circumstances. We also intend to register
shares of common stock for sale that we have issued and may issue under our employee equity incentive plans. Once we register these shares, they will be able to be sold freely in the public market
upon issuance, subject to existing market standoff and/or lock-up agreements. Credit Suisse Securities (USA) LLC and Deutsche Bank Securities Inc. may, in their sole
discretion, permit our officers, directors, employees and current stockholders who are subject to contractual lock-up agreements to sell shares prior to the expiration of the
lock-up agreements. See the "Underwriters" section of this prospectus for more information.
The
market price of the shares of our common stock could decline as a result of sales of a substantial number of our shares in the public market or the perception in the market that the
holders of a large number of shares intend to sell their shares.
Our management will have broad discretion over the use of the proceeds we receive from this offering and might not apply the proceeds in ways that increase the value of your
investment.
Our management will have broad discretion to use our net proceeds from this offering, and you will be relying on the judgment of our
management regarding the application of these proceeds. Our management might not apply these proceeds in ways that increase the value of your investment. We intend to use the net proceeds to us from
this offering primarily for general corporate purposes, including working capital, sales and marketing activities, general and administrative matters, and capital expenditures. We may also use a
portion of the net proceeds to acquire, invest in, or obtain rights to complementary technologies, solutions, or businesses. If we do not apply the net proceeds from this offering in ways that enhance
stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline. You will not have the opportunity to influence our decisions on how we use our net
proceeds from this offering.
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could
decline.
The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish
about us or our business. We currently do not have and may never obtain research coverage by securities analysts, and industry analysts that currently cover us may cease to do so. If no securities
analysts commence coverage of our company, or if industry analysts cease coverage of our company, the trading price for our stock would be negatively impacted. In the event we obtain securities
analyst coverage, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more
of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.
32
Table of Contents
Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new solutions could reduce our ability to
compete and could harm our business.
We may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms, if at
all. If we raise additional equity financing, our stockholders may experience significant dilution of their ownership interests and the per share value of our common stock could decline. If we issue
equity securities in any additional financing, the
new securities may have rights and preferences senior to our common stock. If we engage in debt financing, we may be required to accept terms that restrict our ability to incur additional indebtedness
and force us to maintain specified liquidity or other ratios. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among other
things:
•
develop or enhance our application and services;
•
continue to expand our product development, sales and marketing organizations;
•
acquire complementary technologies, products or businesses;
•
expand operations, in the United States or internationally;
•
hire, train and retain employees; or
•
respond to competitive pressures or unanticipated working capital requirements.
We do not anticipate paying cash dividends, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
We do not anticipate paying cash dividends on our common stock in the future. As a result, only appreciation of the price of our common
stock will provide a return to our stockholders. Investors seeking cash dividends should not invest in our common stock.

INDUSTRY AND MARKET DATA
This prospectus contains estimates and other statistical data, including those relating to our industry, that we have obtained from
industry publications and reports, including reports from IDC, Ponemon Institute and Gartner, Inc. These industry publications and reports generally indicate that they have obtained their information
from sources believed to be reliable, but do not guarantee the accuracy and completeness of their information. This information involves a number of assumptions and limitations, and you are cautioned
not to give undue weight to these estimates, as there is no assurance that any of them will be reached. Although we have not independently verified the accuracy or completeness of the data contained
in these industry publications and reports, based on our industry experience we believe that the publications and reports are reliable and that the conclusions contained in the publications and
reports are reasonable. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in "Risk Factors." These and other
factors could cause our actual results to differ materially from those expressed in the industry publications and reports.
The
reports from Gartner described herein, or the Gartner Reports, represent data, research opinion or viewpoints published as part of a syndicated subscription service, by Gartner, and
are not representations of fact. Each Gartner Report speaks as of its original publication date (and not as of the date of this prospectus) and the opinions expressed in the Gartner Reports are

USE OF PROCEEDS
We estimate that the net proceeds from the sale of shares of our common stock that we are selling in this offering will be
approximately $             million, based on an assumed initial public offering price of $            per share, which is
the midpoint of the estimated offering price range set forth on
the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters' option to purchase
additional shares from us is exercised in full, we estimate that we will receive additional net proceeds of $             million. We will not receive any proceeds from the sale of
shares of
our common stock by the selling stockholders. A $1.00 increase or decrease in the assumed initial public offering price of $            per share would increase or decrease the net proceeds
that
we receive from this offering by approximately $             million, assuming the number of shares offered by us remains the same and after deducting the estimated underwriting
discounts
and commissions payable by us.
We
expect to use the net proceeds that we receive from this offering for working capital and other general corporate purposes. We may also use a portion of the net proceeds that we
receive from this offering for investments in or acquisitions of complementary businesses, products, services, technologies or other assets.
Except
as set forth above, we currently have no specific plans for the use of the net proceeds that we receive from this offering. Accordingly, we will have broad discretion in using the
net proceeds that we receive from this offering. Pending the use of proceeds from this offering as described above, we plan to invest the net proceeds in short-term, interest-bearing
obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.
DIVIDEND POLICY
We have never declared or paid any cash dividends on our common stock. We currently intend to retain any future earnings and do not
expect to pay any cash dividends on our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors and will be
dependent on a number of factors, including our earnings, capital requirements and overall financial conditions. In addition, the terms of our equipment loan agreement with Silicon Valley Bank limit
our ability to pay dividends.

the                  shares of our common
stock offered by us in this offering at an assumed initial public offering price of $            per share, the midpoint of the estimated offering price range set forth on the cover page of
this
prospectus, after deducting the estimated underwriting discounts and commissions and estimated offering expenses; and (ii) the restatement of our certificate of incorporation in connection with
this offering to authorize                  shares of common stock
and                  shares of preferred stock.

DILUTION
If you invest in our common stock in this offering, your interest will be diluted immediately to the extent of the difference between
the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering. Our pro forma net
tangible book value as of September 30, 2011 was $             million, or $            per share of common stock. Pro
forma net tangible book value per share represents the
amount of our total tangible assets less our total liabilities, divided by the number of shares of common stock outstanding as of September 30, 2011, after giving effect to the conversion of
all outstanding shares of our convertible preferred stock into an aggregate of 39,134,535 shares of our common stock immediately upon the completion of this offering.
After
giving effect to the sale by us of                  shares of common stock in this offering at an assumed initial public offering price of
$            per share, which is the
midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses
payable by us, our pro forma as adjusted net tangible book value as of September 30, 2011 would have been approximately $             million, or approximately
$            per
share. This amount represents an immediate increase in pro forma net tangible book value of $            per share to our existing stockholders and an immediate dilution in pro forma net
tangible
book value of approximately $            per share to new investors purchasing shares of common stock in this offering at the assumed initial public offering price, or approximately
        % of the assumed initial public offering price.
The
following table illustrates this dilution:

A
$1.00 increase (decrease) in the assumed initial public offering price of $            per share, which is the midpoint of the estimated offering price range set forth on the cover
page of this prospectus, would increase (decrease) our adjusted net tangible book value per share to new investors by approximately $            and would increase (decrease) dilution per
share to
new investors by approximately $            , assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting
estimated
underwriting discounts and commissions payable by us. In addition, to the extent any outstanding options or the outstanding warrant are exercised, you will experience further dilution.
The

stock into common stock immediately upon the completion of this offering, the differences between the existing stockholders and the new investors purchasing shares of our common stock in this
offering, with respect to the number of shares purchased from us, the total consideration paid or to be paid to us, which includes proceeds received from the issuance of common and convertible
preferred stock, cash received from the exercise of stock options and the average price per share paid by our existing stockholders and by our new investors purchasing shares in this offering at an
assumed offering price of $            per share, which is the midpoint of the estimated offering price range set forth on the cover page of this

$             million and increase (decrease) the percent of total consideration paid by new investors by        %, assuming that the number of
shares offered by us, as
set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions payable by us.
Assuming
the underwriters' option to purchase additional shares is exercised in full, sales by us in this offering will reduce the percentage of shares held by existing stockholders to
        % and will increase the number of shares held by our new investors
to                        , or        %.
The
number of shares of our common stock to be outstanding after this offering is based upon the number of shares of our common stock outstanding as of September 30, 2011 and
excludes:
•
20,227,426 shares of our common stock issuable upon the exercise of stock options outstanding as of September 30,
2011, with a weighted-average exercise price of $1.73 per share;
•
711,800 shares of our common stock issuable upon the exercise of stock options granted after September 30, 2011
through November 30, 2011, with a weighted-average exercise price of $3.29 per share;
•
4,375 shares of our common stock issuable upon the exercise of an outstanding warrant as of September 30, 2011,
with an exercise price of $0.15 per share; and
•
shares of our common stock reserved for future issuance under our 2012 Equity
Incentive
Plan and our 2012 Employee Stock Purchase Plan, each of which will become effective on the first day that our common stock is publicly traded and each of which contains provisions that automatically
increase the number of shares reserved for issuance each year, as more fully described in "Executive Compensation—Employee Benefit Plans."
To
the extent that outstanding options or the outstanding warrant are exercised, you will experience further dilution. If all of our outstanding options and the outstanding warrant were
exercised, our pro forma net tangible book value as of September 30, 2011 would have been $             million, or
$            per share, and the pro forma, as adjusted
net tangible book value after this offering would have been $             million, or $            per share, causing
dilution to new investors of $            per share.
In
addition, to the extent we choose to raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further
dilution to our stockholders.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read in
conjunction with our "Selected Consolidated Financial Data" and our consolidated financial statements and related notes included elsewhere in this prospectus. This discussion contains forward-looking
statements that involve risks and uncertainties. Our actual results could differ materially from those forward-looking statements below. Factors that could cause or contribute to those differences
include, but are not limited to, those identified below and those discussed in the section entitled "Risk Factors" included elsewhere in this prospectus.
Overview
Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most
sensitive data. Our security-as-a-service platform is comprised of an integrated suite of on-demand data protection solutions, including threat
protection, regulatory compliance, archiving and governance, and secure communication.
We
were founded in 2002 to provide a unified solution to help enterprises address their growing data security requirements. Our first solution was commercially released in 2003 to combat
the burgeoning problem of spam and viruses and their impact on corporate email systems. As the threat environment has continued to evolve, we have dedicated significant resources to meet the ongoing
challenges that this highly dynamic environment creates for our customers. In addition, we have invested significantly to expand the breadth of our data protection platform:
•
In 2004, we launched our Regulatory Compliance and Digital Asset Security solutions, designed to prevent the loss of
critical data. These Data Loss Prevention, or DLP, solutions apply our proprietary machine learning and deep content inspection technologies to screen outbound email to prevent the theft or
inadvertent loss of sensitive or confidential information.
•
In 2005, we launched Proofpoint Secure Messaging, our first email encryption solution.
•
In 2006, we combined our email encryption and DLP technologies to develop a new solution for policy-based encryption,
enabling each outgoing message to be inspected for confidential content and automatically encrypted accordingly.
•
In 2007, we began selling our software-based virtual appliance, enabling our customers to deploy our solutions in a
private cloud configuration. We also invested in international expansion of our data center infrastructure, establishing operations in Germany and The Netherlands to support our customers outside of
the United States.
•
In 2008, we introduced Proofpoint Enterprise Archive, a cloud-based email archiving solution that enables businesses to
securely archive both their email and instant message conversations while enabling real-time access to the entire repository for quick and easy electronic discovery, or eDiscovery.
•
In 2009, we launched Proofpoint Encryption, a proprietary email encryption solution that improved the level of integration
across our data protection suite and allowed us to phase out technology licensed from a third party. We also introduced a cloud-based email messaging service.
•
In 2010, we evolved our solutions to address new forms of messaging and information sharing in the enterprise such as
social media and Internet-based collaboration and file sharing applications.
43
Table of Contents
•
In 2011, we achieved FISMA certification for our cloud-based archiving and governance solution, enabling us to serve the
rigorous security requirements of U.S. Federal agencies. We also introduced an integrated security offering in conjunction with VMware for its Zimbra Collaboration Server.
Our
business is based on a recurring revenue model. Our customers pay a subscription fee to license the various components of our
security-as-a-service platform for a contract term that is typically one to three years. At the end of the license term, customers may renew their subscription and
in each year since the launch of our first solution in 2003, we have retained over 90% of our customers. A growing number of our customers increase their annual subscription fees after their initial
purchase by broadening their use of our platform or by adding more users. As our business has grown, our subscription revenue has increased as a percentage of our total revenue, from 81% of total
revenue in the year ended December 31, 2008 to 89% in the nine months ended September 30, 2011.
We
market and sell our solutions to large and mid-sized customers both directly through our field and inside sales teams and indirectly through a hybrid model where our sales
organization actively assists our network of distributors and resellers. We also derive a lesser portion of our revenue from the license of our solutions to strategic partners who offer our solutions
in conjunction with one or more of their own products or services.
We
invoice our customers for the entire contract amount at the start of the term. The majority of these invoiced amounts are treated as deferred revenue on our consolidated balance sheet
and are recognized ratably over the term of the contract. We invoice our strategic partners on a monthly basis, and the associated fees vary based upon the level of usage during the month by their
customers. These amounts are recognized as revenue at the time of invoice.
Our
solutions are designed to be implemented, configured and operated without the need for any training or professional services. For those customers that seek to develop deeper
expertise in the use of our solutions or would like assistance with complex configurations or the importing of data, we offer various training and professional services. In some cases, we provide a
hardware appliance to those customers that elect to host elements of our solution behind their firewall. Increasing adoption of virtualization in the data center has led to a decline in the sales of
our hardware appliances and a shift towards our software-based virtual appliances, which are delivered as a download via the Internet. Our hardware and services offerings carry lower margins and are
provided as a courtesy to our customers. The revenue derived from these offerings has declined from 19% of total revenue in the year ended December 31, 2008 to 11% of total revenue in the nine
months ended September 30, 2011. We view this trend as favorable to our business and expect the overall proportion of total revenue derived from these offerings to continue to gradually
decline.
The
substantial majority of our revenue is derived from our customers in North America. We believe the markets outside of North America offer an opportunity for growth and we intend to
make additional investments in sales and marketing to expand in these markets. Customers from outside of North America represented 19% of total revenue for the nine months ended September 30,
2011 and, 16%, 19% and 17% for the years ended December 31, 2010, 2009 and 2008, respectively. As of September 30, 2011, we had approximately 2,400 customers around the world, including
24 of the Fortune 100. No single partner or customer accounted for more than 10% of our total revenue in 2008, 2009 or 2010 or the nine months ended September 30, 2011.
The
majority of costs associated with generating customer agreements are incurred up front. These upfront costs include direct incremental sales commissions, which are recognized upon
the billing of the contract. Although we expect customers to be profitable over the duration of the customer relationship, these upfront costs may exceed related revenue in earlier periods.
Accordingly, an increase in the mix of new customers as a percentage of total customers would likely negatively impact our operating results. On the other hand, we expect that an increase in the mix
of existing customers as a percentage
44
Table of Contents
of
total customers would positively impact our operating results. As we accumulate customers that continue to renew their contracts, we anticipate that our mix of existing customers will increase.
To
date, our customers have primarily used our solutions in conjunction with email messaging content. We have developed solutions to address the new and evolving messaging solutions such
as social media and file sharing applications, but these solutions are relatively nascent. If customers increase their use
of these new messaging solutions in the future, we anticipate that our growth in revenue associated with email messaging solutions may slow over time. Although revenue associated with our social media
and file sharing applications has not been material to date, we believe that our ability to provide security, archiving, governance and discovery for these new solutions will be viewed as valuable by
our existing customers, enabling us to derive revenue from these new forms of messaging and communication.
While
the majority of our current and prospective customers run their email systems on premise, we believe that there is a trend for large and mid-sized enterprises to migrate these
systems to the cloud. While our current revenue derived from customers using cloud-based email systems is approximately 10% of our total revenue, many of these cloud-based email solutions offer some
form of threat protection and governance services, potentially mitigating the need for customers to buy these capabilities from third parties such as ourselves. We believe that we can continue to
provide security, archiving, governance, and discovery solutions that are differentiated from the services offered by cloud-based email providers, and as such our platform will continue to be viewed
as valuable to enterprises once they have migrated their email services to the cloud, enabling us to continue to derive revenue from this new trend toward cloud-based email deployment models.
We
are currently in the midst of a significant investment cycle in which we have taken steps designed to drive future revenue growth and profitability. For example, we plan to build out
our infrastructure, develop our technology, offer additional security-as-a-service solutions, and expand our sales and marketing personnel both in North America and
internationally. Accordingly, we expect that our total cost of revenue and operating expenses will continue to increase in absolute dollars, limiting our ability to achieve and maintain positive
operating cash flow and profitability in the near term.
Key Metrics
We regularly review a number of metrics, including the following key metrics presented in the unaudited table below, to evaluate our
business, measure our performance, identify trends in our business, prepare financial projections and make strategic decisions. Many of these key metrics, such as adjusted subscription gross profit
and billings, are non-GAAP measures. This non-GAAP information is not necessarily comparable to non-GAAP information of other companies. Non-GAAP
information should not be viewed as a substitute for, or superior to, net loss prepared in accordance with GAAP as a measure of our profitability or liquidity. Users of this financial information
should consider the types of events and transactions for which adjustments have been made. See "Summary Consolidated
45

Information—Reconciliation of Non-GAAP Financial Measures" above for a reconciliation of the non-GAAP information to GAAP.

Subscription revenue.
Subscription revenue represents the recurring subscription fees paid by our customers and recognized as revenue
during the
period for the use of our security-as-a-service platform, typically licensed for one to three years at a time. We consider subscription revenue to be a key business
metric because it reflects the recurring aspect of our business model and is the primary driver of growth for our business over time. The consistent growth in subscription revenue over the past
several years has resulted from our
ongoing investment in sales and marketing personnel, our efforts to expand our customer base, and our efforts to broaden the use of our platform with existing customers.
Adjusted subscription gross profit.
Adjusted subscription gross profit is a non-GAAP financial measure that we calculate as the gross
profit generated by our subscription revenue, adjusted to exclude stock-based compensation and the amortization of intangibles related to prior acquisitions. We believe that adjusted subscription
gross profit provides useful information to investors in understanding and evaluating our operating results in the same manner as our management and board of directors. This metric represents the
gross profit on our recurring subscription revenue and is directly related to our ability to generate profitability. Adjusted subscription gross profit, when measured as a percentage of subscription
revenue, improved from 64% during the nine months ended September 30, 2010 to 72% during the same period in 2011. These improvements resulted from our ongoing efforts to reduce our cost of
subscription revenue through the replacement of technology licensed from third parties with our own proprietary technology in conjunction with improved operating leverage on our data center
infrastructure. Improvements in the gross profit of these subscription services enhance our ability to drive positive cash flow and profitability for our business overall. For more information about
adjusted subscription gross profit, see "Summary Consolidated Financial Information—Reconciliation of Non-GAAP Financial Measures."
Billings.
Billings is a non-GAAP financial measure that is a direct reflection of our overall sales activity in the period. Billings can
be derived by adding the change in the deferred revenue between the start and end of the period to the revenue recognized in the same time frame. Billings consist of all amounts invoiced to customers
for non-cancelable sales transactions and hence are important as they correspond directly to our near-term cash flow. However, trends in billings are not directly correlated to trends in
revenue except when measured over longer periods of time, as billings are affected by a combination of factors including the timing of renewals, the sales of our solutions to both new and existing
customers, the relative duration of contracts sold, and the relative amount of business derived from strategic partners. Each of these elements has unique characteristics in the relationship between
billings and revenue, and as such our billings activity is not closely correlated to revenue over shorter

Components of Our Results of Operations
Revenue
We derive our revenue primarily through the license of various solutions and services on our
security-as-a-service platform on a subscription basis, supplemented by the sales of training, professional services and hardware depending upon our customers'
requirements.
Subscription.
We license our platform and its associated solutions and services on a subscription basis. The fees are charged on a per
user, per year
basis. Subscriptions are typically one to three years in duration. We invoice our customers upon signing for the entire term of the contract. The invoiced amounts billed in advance are treated as
deferred revenue on the balance sheet and are recognized ratably, in accordance with the appropriate revenue recognition guidelines, over the term of the contract (see —Critical Accounting
Policies). We also derive a portion of our subscription revenue from the license of our solutions to strategic partners. We bill these strategic partners monthly. As our business has grown, our
subscription revenue has increased as a percentage of our total revenue, from 81% of total revenue in the year ended December 31, 2008 to 89% in the nine months ended September 30, 2011.
Hardware and services.
We provide hardware appliances as a convenience to our customers and as such it represents a small part of our
business. Our
solutions are designed to be implemented, configured and operated without the need for any training or professional services. For those customers that seek to develop deeper expertise in the use of
our solutions or would like assistance with complex configurations or the importing of data, we offer various training and professional services. We typically invoice the customer for hardware at the
time of shipment. Effective January 1, 2011, we adopted the revenue recognition guidance of Accounting Standards Update (ASU) 2009-13 and ASU 2009-14, which mandate that
our revenue derived from the sale of hardware be recognized at the time of shipment. Prior to the adoption of this new accounting guidance, hardware revenue was recognized ratably over the duration of
the contract. We typically invoice customers for services at the time the order is placed and recognize this revenue ratably over the term of the contract. On occasion, customers may retain us for
special projects such as archiving import and export services; these types of services are recognized upon completion of the project. The revenue derived from these hardware and services offerings has
declined from 19% of total revenue in the year ended December 31, 2008 to 11% of total revenue in the nine months ended September 30, 2011. We view this
trend as favorable to our business and expect the overall proportion of revenue derived from these offerings to continue to decline gradually.
Total Cost of Revenue
Cost of Subscription Revenue.
Cost of subscription revenue primarily includes personnel costs, consisting of salaries, benefits,
bonuses, and
stock-based compensation, for employees who provide support services to our customers and operate our data centers. Other costs include fees paid to contractors who supplement our support and data
center personnel; expenses related to the use of third-party data centers in both the United States and internationally; depreciation of data center equipment; amortization of licensing fees and
royalties paid for the use of third-party technology; amortization of capitalized research and development costs; and the amortization of intangible assets related to prior acquisitions. Our cost of
subscription revenue has declined in recent periods as a percentage of its associated revenue as we have replaced third-party licensed technology with our proprietary technology, and we expect the
benefit of these initiatives to continue in future periods.
47
Table of Contents
Cost of Hardware and Services Revenue.
Cost of hardware and services revenue includes personnel costs for employees who provide
training and
professional services to our customers as well as the cost of server hardware shipped to our customers that we procure from third parties and configure with our software solutions. Effective
January 1, 2011, in conjunction with the adoption of the new revenue recognition guidance, the cost of hardware is expensed at the time of shipment. Prior to the adoption of this new guidance,
these hardware costs were recognized ratably over the duration of the contract with which they were sold. Our cost of hardware and services as a percentage of its associated revenue has been
relatively consistent from period to period in the past, but with the adoption of our new accounting guidance we expect that it may gradually increase as a percentage of hardware and services revenue
in future periods.
Operating Expenses
Our operating expenses consist of research and development, sales and marketing, and general and administrative expenses. Personnel
costs, which consist of salaries, benefits, bonuses, and stock-based compensation, are the most significant component of our operating expenses. Our headcount increased from 158 employees on
December 31, 2007 to 348 employees as of September 30, 2011. As a result of this growth in headcount, operating expenses have increased significantly over these periods. We expect
personnel costs to continue to increase in absolute dollars as we hire new employees to continue to grow our business.
Research and Development.
Research and development expenses include personnel costs, consulting services and depreciation. We expect to
continue to
devote substantial resources to research and development in an effort to continuously improve our existing solutions as well as to develop new offerings. We believe that these investments are
necessary to maintain and improve our competitive position. Our research efforts include both software developed for our internal use on behalf of our customers as well as software elements to be used
by our customers in their own facilities. To date, for software developed for internal use on behalf of our customers, we have capitalized costs of approximately $0.4 million, all of which
occurred in the nine months ended September 30, 2011, and will be amortized as cost of subscription revenue over a two-year period. Based on our current plans, we expect to capitalize a similar
portion of our development costs in the future. For the software developed for use on our customers' premises, the costs associated with the development work between technological feasibility and the
general availability has not been material and as such we have not capitalized any of these development costs to date.
Sales and Marketing.
Sales and marketing expenses include personnel costs, sales commissions, and other costs including travel and
entertainment,
marketing and promotional events, public relations and marketing activities. All of these costs are expensed as incurred, including sales commissions. These costs also include amortization of
intangible assets as a result of our past acquisitions. We plan to continue to invest in growing our sales and marketing operations, both domestically and internationally. Our sales personnel are
typically not immediately productive, and therefore the increase in sales and marketing expenses we incur when we add new sales representatives is not immediately offset by increased revenue and may
not result in increased revenue over the long-term if these new sales people fail to become productive. The timing of our hiring of new sales personnel and the rate at which they generate
incremental revenue will affect our future financial performance. We expect that sales and marketing expenses will continue to increase in absolute dollars and be among the most significant components
of our operating expenses.
General and Administrative.
General and administrative expenses include personnel costs, consulting
services, audit fees, tax services, legal expenses and other general corporate items. We expect our general and administrative expenses to increase in future periods as we continue to expand our
operations, hire additional personnel and transition from being a private company to a public company.

Table of Contents
Total Other Income (Expense), Net
Total other income (expense), net, consists of interest income (expense), net and other income (expense), net. Interest income
(expense), net, consists primarily of interest income earned on our cash and cash equivalents offset by the interest expense for our capital lease payments and borrowings under our equipment loans.
Other income (expense), net, consists primarily of the net effect of foreign currency transaction gain or loss.
Provision for Income Taxes
The provision for income taxes is related to certain state and foreign income taxes. As we have incurred operating losses in all
periods to date and recorded a full valuation allowance against our deferred tax assets, we have not historically recorded a provision for federal income taxes. Realization of any of our deferred tax
assets depends upon future earnings, the timing and amount of which are uncertain. Utilization of our net operating losses may be subject to substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code and similar state provisions. An analysis was conducted through 2009 to determine whether an ownership change had occurred since inception. The
analysis indicated that although an ownership change occurred in a prior year, the net operating losses and research and development credits would not expire before utilization. In the event we have
subsequent changes in ownership, net operating losses and research and development credit carryovers could be limited and may expire unutilized.

Subscription revenue increased $11.0 million, or 27%, for the nine months ended September 30, 2011 as compared to the same period in
2010. This increase was driven by growth both in North America as well as internationally as our ongoing investment in sales and marketing resources, coupled with an ongoing improvement in economic
conditions, resulted in improved demand for our platform worldwide.
Hardware
and services revenue increased $1.4 million, or 26%, for the nine months ended September 30, 2011 as compared to the same period in 2010. This increase was
attributable to our adoption of new revenue recognition guidance (as more fully described in our Critical Accounting Policies) effective January 1, 2011 under which revenue from sales of
hardware appliances began to be recognized when sold.

Cost of subscription revenue decreased $0.4 million, or 2%, for the nine months ended September 30, 2011 as compared to the same
period in 2010. The decrease in cost of subscription revenue was primarily attributable to a $0.9 million decrease in royalty expense driven by the replacement of third-party licensed
technology with our proprietary technology, as well as improved economic terms associated with other ongoing licensing agreements. We expect that the combination of these two initiatives will also
continue to contribute to reduced royalty expenses in future periods. These savings were partially offset by increased data center costs of $0.3 million associated with ongoing growth in usage
by new and existing customers.
Cost
of hardware revenue and services revenue increased $1.5 million, or 49%, for the nine months ended September 30, 2011 as compared to the same period in 2010. This
increase was primarily attributable to the adoption of the new revenue recognition guidance effective January 1, 2011 under which costs from sales of hardware appliances are now recognized when
the associated hardware revenue is recognized. Accordingly, $1.1 million of this cost increase was a result of the change in revenue recognition guidance while $0.2 million was due to
the ratable recognition of deferred costs for hardware appliance sales closed prior to the adoption of the new revenue recognition guidance effective January 1, 2011.

increase in travel expenses of $0.8 million. Additionally, as our business grew, commission expense increased by $1.0 million and marketing program spending increased
$0.5 million.

Hardware
and services revenue grew $0.7 million, or 12%, for 2010 as compared to 2009. This growth was primarily due to a modest increase in the sale of both hardware and
professional services. The relatively slow growth in hardware and services as compared to subscription revenue reflects the ongoing shift in deployment models towards our cloud-based and virtual
appliance solutions.

Hardware and services revenue decreased $0.7 million, or 10%, for the year ended December 31, 2009 as compared to 2008 as a direct result of the
increasing demand for our cloud-based services which require no hardware appliances to be sold to customers as part of delivering the service.

data center costs increasing $2.2 million and depreciation and amortization by $1.5 million. Headcount expansion in support of this growth resulted in $1.6 million of additional
personnel costs. Amortization of developed technology increased $1.9 million, which represents a full year of amortization expense related to an acquisition in June 2008.
Cost
of hardware and services revenue decreased $0.5 million, or 14%, for 2009 as compared to 2008. This resulted from the increasing deployment of our cloud-based services.

Research
and development expenses increased by $0.9 million, or 8%, for 2009 as compared to 2008. This growth was primarily due to an increase in headcount over the prior year as
we continued to invest in expanding and enhancing our solutions. This resulted in an increase of $1.4 million in personnel costs, offset by a decrease of $0.3 million in outside services
due to completion of a third-party certification project in 2008 as well as a $0.2 million savings resulting from changing Internet service providers.

Liquidity and Capital Resources
Since our inception, we have relied principally on sales of our preferred stock to fund our operating activities. To date, we have
raised $92.8 million of equity capital. Additionally, we have utilized equipment lines to fund capital purchases.
We
entered into a new equipment loan agreement with Silicon Valley Bank in April 2011 for an aggregate loan principal amount of $6.0 million. Interest on the advances are equal to
prime rate plus 0.50%. As of September 30, 2011, the interest rate on the advances was 4.50%. We have the ability to draw down on this equipment line through April 19, 2012. Each drawn
amount is due 48 months after
funding. Borrowings outstanding under the equipment loan at September 30, 2011 were $2.9 million. Equipment financed under this loan arrangement is collateralized by the respective
assets underlying the loan. The loan includes a covenant that requires us to maintain cash and cash equivalents plus net accounts receivables of at least two times the amount of all outstanding
indebtedness. As of September 30, 2011, we were in compliance with this financial covenant.
Based
on our current level of operations and anticipated growth, we believe that our existing sources of liquidity will be sufficient to fund our operations for at least the next
12 months. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, and the timing and extent of
spending to support product development efforts and expansion into new territories, and the timing of introductions of new features and enhancements to our solutions. To the extent that existing cash
and cash equivalents and cash from operations are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. We may also seek
to invest in or acquire complementary businesses, applications or technologies, any of which could also require us to seek additional equity or debt financing. Additional funds may not be available on
terms favorable to us or at all.

Net Cash Flows Provided by (Used in) Operating Activities
Our net loss and cash flows from operating activities are significantly influenced by our investments in headcount and data center
operations to support anticipated growth. Our cash flows are also influenced by cash payments from customers. We invoice customers for the entire contract amount at the start of the term, and as such
our cash flow from operations is also affected by the length of a customer contract.
Cash
used in operating activities for the nine months ended September 30, 2011 of $(0.3 million) was the result of a net loss of $13.7 million, offset by
non-cash expenditures of $9.1 million, which included depreciation, amortization and stock-based compensation expense. This was further offset by deferred revenue and product costs
of $5.5 million as a result of our subscription based revenue model. The remaining use of funds of $1.3 million was from the net change in working capital items.
Cash
provided by operating activities for the nine months ended September 30, 2010 of $1.5 million was the result of a net loss from operations of $15.1 million.
This was offset by non-cash expenditures of $8.6 million which includes depreciation, amortization, and stock-based compensation expense. This was further offset by deferred revenue
and product costs of $8.7 million as a result of our subscription based revenue model. The remaining use of funds of $0.6 million was from the net change in working capital items.
Cash
provided by operating activities in 2010 of $3.4 million was the result of a net loss of $20.9 million, offset by non-cash expenditures of
$11.4 million, which included depreciation, amortization and stock-based compensation expense, and by deferred revenue and product costs of $13.4 million as a result of our subscription
based revenue model. The remaining use of funds of $0.5 million was from the net change in working capital items.
Cash
used in operating activities in 2009 of $3.7 million was the result of a net loss of $19.7 million, offset by non-cash expenditures of $10.0 million
which included depreciation, amortization and stock-based compensation expense, and by deferred revenue and product costs of $9.2 million. The remaining use of funds of $3.2 million was
from the net change in working capital items.
Cash
used in operating activities in 2008 of $7.6 million was the result of a net loss of $25.9 million, offset by non-cash expenditures of $6.3 million
which included depreciation, amortization and stock-based compensation expense, and by deferred revenue and product costs of $11.4 million as a result of our subscription based revenue model.
The remaining use of funds of $0.7 million was from the net change in working capital items.

Net Cash Flows Provided by (used in) Investing Activities
Our primary investing activities have consisted of capital expenditures in support of expanding our infrastructure and workforce and
the purchase and sale of short-term investments. As our business grows, we expect our capital expenditures and our investment activity to continue to increase.
We
used $8.3 million of cash in investing activities during the nine months ended September 30, 2011. This was primarily from the net purchase of $4.4 million in
short-term investments. In addition, we used $3.8 million to purchase equipment for infrastructure expansion.
Investing
activities for the nine months ended September 30, 2010 resulted in net proceeds of $0.7 million. This was primarily from $2.8 million in net proceeds from
the sale of short-term investments, offset by $2.0 million of equipment purchases used for infrastructure expansion.
Investing
activities for the year ended December 31, 2010 resulted in net proceeds of $0.3 million. This was primarily from $3.7 million of net proceeds from
short-term investments, offset by $3.4 million of equipment purchases used for infrastructure expansion and other fixed assets.
We
used $5.1 million of cash in investing activities in 2009. The main uses were a $6.6 million acquisition and $2.5 million used for infrastructure equipment and
other fixed assets, offset by net proceeds from short-term investments of $4.0 million.
We
used $16.0 million of cash in investing activities in 2008. We used $7.0 million for an acquisition, $6.2 million for net purchases of short-term
investments and $2.9 million for infrastructure equipment and other fixed assets.
Net Cash Flows Provided by (Used in) Financing Activities
Cash provided by financing activities for the nine months ended September 30, 2011 was $3.6 million. This consisted of
$0.9 million of proceeds from the exercise of stock options and borrowings under our new equipment line of which $2.9 million during this period, partially offset by repayment of
equipment financing loans of $0.2 million.
Cash
provided by financing activities for the nine months ended September 30, 2010 was $2.2 million. This consisted of proceeds from sales of our Series F preferred
stock of $1.5 million along with $1.1 million of proceeds from the exercise of employee stock options, partially offset by repayment of equipment financing loans of $0.4 million.
Cash
provided by financing activities in 2010 was $1.4 million. This consisted of proceeds from sales our Series F preferred stock financing of $1.5 million along
with $1.2 million from the exercise of employee stock options, partially offset by repayment of equipment financing loans of $0.5 million and $0.8 million towards earn-out
payments.
Cash
provided by financing activities in 2009 was $4.8 million. This consisted of proceeds from sales of our Series F preferred stock of $5.0 million along with
$0.2 million from the exercise of employee stock options, partially offset by repayment of equipment financing loans of $0.4 million.
Cash
provided by financing activities in 2008 was $27.6 million. This consisted of proceeds from the sales of our Series F preferred stock of $27.8 million along
with $0.2 million from the exercise of employee stock options, partially offset by repayment of equipment financing loans of $0.4 million.

We entered into a new equipment loan agreement with Silicon Valley Bank in April 2011 for an aggregate loan principal amount of
$6.0 million. For more information about our equipment loan agreement please see "Liquidity and Capital Resources."
In
March 2011, we entered into a lease agreement to occupy an additional 22,121 square feet of office space at our headquarters facility. The lease term is 39 months for 78,338
square feet in the aggregate, with a monthly rental of $74,338 commencing on April 1, 2011, and expiring on June 30, 2014.
We
completed an acquisition in October 2009 that included an earn-out payment of up to $1.0 million to stockholders of the acquired company in the event that certain
revenue targets were achieved. We currently anticipate that the full amount of this payment will be made in December 2011.
We
have recorded a liability for sales and use taxes. A variety of factors could affect the liability, which factors include recovery of amounts from customers and any changes in
relevant statutes in the various states in which we have done business. To the extent that the actual amount of our liabilities for sales and use taxes materially differs from the amount we have
recorded on our consolidated balance sheet, our future results of operations and cash flows could be negatively affected.
Under
the indemnification provisions of our standard customer agreements, we agree to indemnify, defend and hold harmless our customers against, among other things, infringement of any
patents, trademarks or copyrights under any country's laws or the misappropriation of any trade secrets arising from the customer's legal use of our solutions. Our exposure under these indemnification
provisions is generally limited to the total amount paid by the customer under the applicable customer agreement. However, certain indemnification provisions potentially expose us to losses in excess
of the aggregate amount paid to us by the customer under the applicable customer agreement. No material claims have been made against us pursuant to these indemnification provisions to date.

Off-Balance Sheet Arrangements
During the periods presented, we did not have, nor do we currently have, any relationships with unconsolidated entities or financial
partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet
arrangements or other contractually narrow or limited purposes. We are therefore not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in those types of
relationships.
Quantitative and Qualitative Disclosures about Market Risk
We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our
business. These risks primarily include interest rate, foreign exchange and inflation risks, as well as risks relating to changes in the general economic conditions in the countries where we conduct
business. To reduce certain of these risks, we monitor the financial condition of our large clients and limit credit exposure by collecting in advance and setting credit limits as we deem appropriate.
In addition, our investment strategy has been to invest in financial instruments that are highly liquid and readily convertible into cash with maturity dates within three months from the date of
purchase. To date, we have not used derivative instruments to mitigate the impact of our market risk exposures. We have also not used, nor do we intend to use, derivatives for trading or speculative
purposes.
Interest Rate Risk
We are exposed to market risk related to changes in interest rates. Our investments are considered cash equivalents and primarily
consist of money market funds, corporate debt securities and a certificate of deposit. As of September 30, 2011, we had cash, cash equivalents, and short-term investments of
$12.1 million. The carrying amount of our cash, cash equivalents and short-term investments reasonably approximates fair value, due to the short maturities of these investments. The
primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We do not enter into investments
for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our
investments. Due to the short-term nature of our investment portfolio, we believe only dramatic fluctuations in interest rates would have a material effect on our investments. As such we
do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.
As
of September 30, 2011 we had borrowings outstanding with principal amounts of $3.0 million. Our outstanding long-term borrowings consist of fixed and
variable interest rate financial instruments. The interest rates of our borrowings range from 2.9% to 10.6%. A hypothetical 10% increase or decrease in interest rates relative to our current interest
rates would not have a material impact on the fair values of all of our outstanding borrowings. Changes in interest rates would, however, affect operating results and cash flows, because of the
variable rate nature of our borrowings. A hypothetical 10% increase or decrease in interest rates relative to interest rates at December 31, 2010 would result in an insignificant impact to
interest expense for 2011.
Foreign Currency Risk
Our sales to international customers are generally U.S. dollar-denominated. As a result, there are no significant foreign currency
gains or losses related to these transactions. The functional currency for our wholly owned foreign subsidiaries is the U.S. dollar. Accordingly, the subsidiaries remeasure monetary assets and
liabilities at period-end exchange rates, while nonmonetary items are remeasured at historical rates. Income and expense accounts are remeasured at the average exchange rates in effect
61
Table of Contents
during
the year. Remeasurement adjustments are recognized in the statement of operations as foreign currency transaction gains or losses in the year of occurrence. Aggregate foreign currency
transaction losses included in determining net loss were $166,000 in 2008, $177,000 in 2009 and $187,000 for fiscal year 2010 and $58,000 for the nine months ended September 30, 2010
respectively. For the nine months ended September 30, 2011, however, there was a net transaction gain of $93,000. Transaction gains and losses are included in other income (expense), net.
As
our international operations grow, our risks associated with fluctuation in currency rates will become greater, and we will continue to reassess our approach to managing this risk. In
addition, currency fluctuations or a weakening U.S. dollar can increase the costs of our international expansion. To date, we have not entered into any foreign currency hedging contracts, since
exchange rate fluctuations have not had a material impact on our operating results and cash flows. Based on our current international structure, we do not plan on engaging in hedging activities in the
near future.
Inflation Risk
We do not believe that inflation has had a material effect on our business, financial condition or results of operations. Nonetheless,
if our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm
our business, financial condition and results of operations.
Critical Accounting Policies
Our management's discussion and analysis of our financial condition and results of operations are based on our consolidated financial
statements, which have been prepared in accordance with GAAP. GAAP requires us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the dates of
the consolidated financial statements, the disclosure of contingencies as of the dates of the consolidated financial statements, and the reported amounts of revenue and expenses during the periods
presented. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities. If actual results or events differ materially from those contemplated by us in making these estimates, our reported financial condition
and results of operations for future periods could be materially affected. See "Risk Factors" for certain matters that may affect our future financial condition or results of operations. An accounting
policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are uncertain at the time the estimate is made, if different estimates
reasonably could have been used, or if the changes in estimate that are reasonably likely to occur could materially impact the financial statements. Our management has discussed the development,
selection and disclosure of these estimates with the audit committee of our board of directors.
The
following critical accounting policies reflect significant judgments and estimates used in the preparation of our consolidated financial statements:
•
Revenue recognition and deferred revenue;
•
Stock-based compensation;
•
Allowance for doubtful accounts;
•
Capitalized software costs;
•
Impairment of long lived assets; and
•
Income taxes.

Table of Contents
Revenue Recognition and Deferred Revenue
We derive our revenue primarily from two sources: (1) subscription revenue for rights related to the use of our
security-as-a-service platform and (2) hardware, training, and professional services revenue provided to customers related to their use of our platform.
Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to three years, and consists of (i) subscription fees from
the licensing of our security-as-a-service platform, (ii) subscription fees for access to the on-demand elements of our platform and
(iii) subscription fees for the right to access our customer support services.
We
apply the provision of Accounting Standard Codification (ASC) 985-605, "Software Revenue Recognition," and related interpretations, to all transactions involving the
licensing of software, as well as related support, training, and other professional services. ASC 985-605 requires revenue earned on software arrangements involving multiple elements such
as software license, support, training, and other professional services to be allocated to each element based on the relative fair values of these elements. The fair value of an element must be based
on vendor-specific objective evidence (VSOE) of fair value. VSOE of fair value of each element is based on the price charged when the element is sold separately. Revenue is recognized when all of the
following criteria are met as set forth in ASC 985-605:
•
Persuasive evidence of an arrangement exists;
•
Delivery has occurred;
•
The fee is fixed or determinable; and
•
Collectability is probable.
We
have analyzed all of the elements included in our multiple element arrangements and have determined that we do not have sufficient VSOE of fair value to allocate revenue to our
subscription and software license agreements, support, training, and professional services. We defer all revenue under the arrangement until the commencement of the subscription services and any
associated professional services. Once the subscription services and the associated professional services have commenced, the entire fee from the arrangement is recognized ratably over the remaining
period of the arrangement. If the professional services are essential to the functionality of the subscription, then the revenue recognition does not commence until such services are completed.
Our
hosted on-demand service agreements do not provide customers with the right to take possession of the software supporting the hosted service. We recognize revenue from
our on-demand services in accordance with ASC 605-20, and as such recognize revenue when the following criteria are met:
•
Persuasive evidence of an arrangement exists;
•
Delivery of our obligations to our customers has occurred;
•
Collection of the fees is probable; and
•
The amount of fees to be paid by the customer is fixed or determinable.
In
October 2009, the Financial Accounting Standards Board (FASB) amended the accounting guidance for multiple element arrangements (ASU 2009-13)
to:
•
Provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be
separated, and how the arrangement consideration should be allocated among its elements;
63
Table of Contents
•
Require an entity to allocate revenue in an arrangement that has separate units of accounting using best estimated selling
price (BESP) of deliverables if a vendor does not have VSOE of fair value or third-party evidence of selling price (TPE); and
•
Eliminate the use of the residual method and require an entity to allocate revenue using the relating selling price method
to the separate unit of accounting.
Concurrently,
the FASB amended the accounting guidance for revenue recognition (ASU 2009-14) to exclude hardware appliances containing software components and hardware
components that function together to deliver the hardware appliance's essential functionality from the scope of the software revenue recognition guidance of ASC 985-605.
Prior
to the adoption of ASU 2009-14, revenue derived from hardware appliance sales were recognized based on the software revenue recognition guidance. We could not establish
VSOE of fair value for the undelivered elements in the arrangement, and therefore the entire fee from the arrangement was recognized ratably over the contractual term of the agreement. In addition, we
were unable to establish VSOE of fair value of our hosted on-demand service agreements, and therefore the entire fee for the agreement was recognized ratably over the contractual term of
the agreement.
As
a result of the adoption of this new accounting guidance, revenue derived from our subscription services and hardware appliance sales are no longer subject to industry-specific
software revenue recognition guidance. For all arrangements within the scope of the new guidance, including our hosted on-demand services, we evaluate each element in a multiple element
arrangement to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when the delivered item has standalone value and delivery of the
undelivered element is probable and within our control. Revenue derived from the licensing of the security-as-a-service platform continue to be accounted for in
accordance with the industry specific revenue recognition guidance.
When
we are unable to establish the selling price of our non-software deliverables using VSOE or TPE, we use BESP in our allocation of arrangement consideration. The
objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We determine BESP for an individual element within a multiple
element revenue arrangement using the same methods utilized to determine the selling price of an element sold on a standalone basis. We estimate the selling price for our subscription solutions by
considering internal factors such as historical pricing practices and we estimate the selling price of our hardware and services using a combination of our historical costs paired with external
measurements regarding the pricing of similar products and services in similar industries. As there is a significant amount of judgment when determining BESP, we regularly review all of our
assumptions and inputs around BESP and maintain internal controls over the establishment and updates of these estimates.
Hardware
appliance revenue is recognized upon shipment. Subscription and support revenue are recognized over the contract period commencing on the start date of the contract.
Professional services and training, when sold with hardware appliances or subscription and support services, are accounted for separately when those services have standalone value. In determining
whether professional services and training services can be accounted for separately from subscription and support services, we consider the following factors: availability of the services from other
vendors, the nature of the services, and the dependence of the subscription services on the customer's decision to buy the professional services. If professional services and training do not qualify
for separate accounting, we recognize the professional services and training ratably over the contract term of the subscription services.
Delivery
generally occurs when the hardware appliance is delivered to a common carrier freight on board shipping point by us or the hosted service has been activated and communicated to
the customer accordingly. Our fees are typically considered to be fixed or determinable at the inception of an
64
Table of Contents
arrangement
and are negotiated at the outset of an arrangement, generally based on specific products and quantities to be delivered. In the event payment terms are provided that differ significantly
from our standard business practices, the fees are deemed to not be fixed or determinable and revenue is recognized as the fees become paid.
We
assess collectability based on a number of factors, including credit worthiness of the customer and past transaction history of the customer. Through September 30, 2011, we
have not experienced any significant credit losses.
We
elected to adopt this new guidance in the first quarter of 2011 for new and materially modified revenue arrangements originating after January 1, 2011. Prior to the adoption of
this new accounting guidance, hardware revenue was recognized ratably over the duration of the contract. Accordingly, as of December 31, 2010, our deferred revenue balance reflected amounts yet
to be recognized under our then-current accounting practices. These deferred amounts will continue to be recognized ratably under their original amortization schedules until the end of the associated
contract term. As such, until the end of these contract periods, we will recognize hardware revenue both from sales in prior periods subject to the original accounting guidance as well as from sales
in current periods subject to the new accounting guidance, with the principal impact being in 2011 and to a lesser extent 2012 and future periods. Given the marginal contribution toward profitability
of our hardware appliances, we do not expect this transition to contribute materially toward our profitability.
Stock-Based Compensation
Effective January 1, 2006, we adopted ASC 718, which requires non-public companies that used the minimum
value method under ASC 718 for either recognition or pro forma disclosures to apply ASC 718 using the prospective-transition method. In accordance with ASC 718, we recognize the
compensation cost of employee stock-based awards granted subsequent to December 31, 2005 in the statement of operations using the straight-line method over the vesting period of the
award.

As of each stock option grant date, we considered the fair value of the underlying common stock, determined as described below, in order to
establish the options exercise price.
As
there has been no public market for our common stock prior to this offering, and therefore a lack of company-specific historical and implied volatility data, we have determined the
share price volatility for options granted based on an analysis of reported data for a peer group of companies that granted options with substantially similar terms. We analyzed a population of
possible comparable companies and selected those for our peer group that we considered to be the most comparable to us in terms of industry business model, revenue, growth and gross profit margins.
The expected volatility of options granted has been determined using an average of the historical volatility measures of this peer group of companies for a period equal to the expected life of the
option. We intend to continue to consistently apply this process using the same or similar entities until a sufficient amount of historical information regarding the volatility of our own share price
becomes available, or unless circumstances change such that the identified entities are no longer similar to us. In this latter case, more suitable entities whose share prices are publicly available
would be utilized in the calculation.
The
expected life of options granted has been determined utilizing the "simplified" method as prescribed by the SEC's Staff Accounting Bulletin, or SAB, No. 107, Share-Based
Payment , or SAB 107. The risk-free interest rate is based on a daily treasury yield curve rate whose term is consistent with the expected life of the stock options. We have not,
historically, paid and, in the future, do not anticipate paying cash dividends on our shares of common stock and therefore, the expected dividend yield is assumed to be zero.
In
addition, ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
We apply an estimated forfeiture rate based on our historical forfeiture experience.

We used a third-party valuation firm to assist us with the development of contemporaneous valuations. Our board of directors determined the fair
value of our common stock on the date of grant based on a number of factors including:
•
Our performance, growth rate and financial condition at the approximate time of the option grant;
•
The value of companies that we consider peers based on a number of factors including, but not limited to, similarity to us
with respect to industry, business model, stage of growth, financial risk or other factors;
•
Changes in the company and our prospects since the last time the board approved option grants and made a determination of
fair value;
•
Amounts recently paid by investors for our common stock and convertible preferred stock in arm's-length transactions with
stockholders;
•
The rights, preferences and privileges of preferred stock relative to those of our common stock;
•
Future financial projections; and
•
Valuations completed in conjunction with, and at the time of, each option grant.
For
our valuations we calculated the enterprise value by applying both the market approach and the income approach. In the market approach the valuations and outcomes of comparable peer
companies in the public market were reviewed. The income approach consists of a discounted cash flow analysis. The methodology we use derives equity values utilizing a probability-weighted expected
return method. Under this approach, various potential liquidity events are identified and each possible outcome is assigned a probability based on discussion with our management. For each of the
possible events, a range of future equity values is estimated based on both the market and income approaches where applicable, applying various possible dates for each event. The timing of these
events is based on discussion with our management. For each future equity liquidity value scenario, the rights and preferences of each stockholder class are considered in order to determine the
appropriate allocation of value to common shares. The value of each common share is then multiplied by a discount factor derived from the calculated discount rate and the expected timing of the event.
The value per common share, taking into account sensitivities to the timing of the event, is then multiplied by an estimated probability for each of the possible events. The calculated value per
common share under a private company scenario is then discounted for a lack of marketability. A probability-weighted value per share
67
Table of Contents
of
common stock is then determined. Under this approach, the value of our common stock is estimated based upon an analysis of values for our common stock assuming the following various possible future
events for the company, including initial public offering, strategic merger or sale, remaining a private company, and dissolution of the business with no resulting value to common stockholders.
Discussion of specific valuation inputs for 2010 and 2011
February 9, March 9 and April 20, 2010.
During the first quarter of 2010, total revenue grew at approximately 5%
compared to the
preceding quarter, and both profitability and cash flow were negative. Given that these grants occurred within a span of approximately 60 days and there were no material changes to the business during
that time, we used the same sets of assumptions in assessing the valuation for all three dates. For these grants, we determined our valuation using the income and market approaches with 60% weighting
assigned to the market approach and 40% assigned to the income approach. We then applied the option pricing method, where the rights of the various holders of preferred and common stock are evaluated
against these two valuations in order to arrive at a fair value associated with the common stock. In addition, this analysis used a 25% lack of marketability discount. Based on all of these factors,
our board of directors determined a fair value of our common stock to be $1.94 per share at each respective date.
July 30, 2010.
In July 2010, our total revenue continued to grow at a modest pace of 4% compared to the preceding quarter during
the early
stages of the economic recovery. In estimating the fair value as of July 30, 2010, key assumptions included a time to liquidity of greater than 12 months for an initial public offering
or a strategic merger or sale of the company, with the expected outcomes weighted 40% towards an initial public offering, 30% towards a strategic merger or sale, 25% towards remaining a private
company and 5% towards a liquidation scenario. In addition, this analysis used a 25% lack of marketability discount as there was not a perceived change in the likelihood of a liquidation event. Based
on all these factors, the board of directors determined a fair value of our common stock to be $2.49 per share.
October 28, 2010.
In October 2010, our total revenue continued to grow and we generated cash flow from operations for the first
time since the
economic downturn. In estimating the fair value as of October 28, 2010, key assumptions included a time to liquidity of greater than 12 months in terms of an initial public offering, strategic
merger or sale of the company, with the expected outcomes weighted 40% towards an initial public offering, 30% towards a strategic merger or sale, 25% towards remaining a private company and 5%
towards a liquidation scenario. In addition, this analysis used a 20% lack of marketability discount. Despite our 4% quarter over quarter revenue growth, a pullback in stock valuations as evidenced by
a decline in the S&P 500 index of approximately 10% over this same period of time resulted in a decline in valuations for our peer group. Based on all these factors, the board of directors
determined a fair value of our common stock to be $2.44 per share.
December 15, 2010.
In December 2010, our total revenue was growing at a rate of almost 10% compared to the preceding quarter and
we continued
to generate cash from operations. In estimating the value for December 15, 2010, key assumptions included an expected time to an initial public offering of one year and the lowering of our
marketability discount to 17.5%, given the promising acceleration in the growth of our business and positive cash flow. The expected time to strategic merger or sale in the event of not completing a
public offering was still deemed to be greater than 12 months. The expected outcomes were weighted 40% towards an initial public offering, 55% towards a strategic merger or sale and 5% towards
a liquidation scenario. Based on all these factors, the board of directors determined a fair value of our common stock to be $2.69 per share.
January 27, 2011.
In January 2011, our business had performed as expected based on our observations on December 15, 2010. Given that a
little over a
month had passed since our prior valuation and there were no material changes to the business since that time, we applied the same sets
68
Table of Contents
of
assumptions as ones used on December 15, 2010 in assessing the valuation and as such we did not have an updated valuation report prepared by our valuation firm. Accordingly, our board of
directors determined a fair value of our common stock to remain $2.69 per share.
April 29, 2011.
In April 2011, our total revenue growth rate had slowed to 4% compared to the preceding quarter and we were no
longer
generating cash from operations. In estimating the fair value as of April 29, 2011, key assumptions included an expected time to an initial public offering deemed to be greater than 12 months
given the slowdown in the business. The expected time for a strategic merger or sale was also estimated to be greater than 12 months. The expected outcomes were weighted 40% towards an initial
public offering, 55% towards a strategic merger or sale and 5% towards a liquidation scenario. In addition, this analysis used a 17% lack of marketability discount. Based on all these factors, the
board of directors determined a fair value of our common stock to be $2.74 per share.
August 5, 2011.
In August 2011, our total revenue growth rate continued at a slower rate of 3% compared to the preceding quarter
and we
continued to generate negative cash flow. In estimating the fair value as of August 5, 2011, key assumptions included an expected time to an initial public offering, strategic merger or sale to
be greater than 12 months. The expected outcomes were weighted 40% towards an initial public offering, 55% towards a strategic merger or sale and 5% towards a liquidation scenario. In addition,
this analysis used a 15% lack of marketability discount, as the ongoing growth of the business implied a gradual improvement in the potential marketability of the common stock. Based
on all these factors, the board of directors determined a fair value of our common stock to be $2.88 per share.
October 12, 2011.
In October 2011, our board of directors approved a plan to proceed with the preparation for a filing for an
initial public
offering. While the timing of the offering was uncertain, this decision substantially increased the likelihood of a public offering as compared to other liquidation events and, as such, the expected
outcome weighting for an initial public offering was changed to 95%, with the remaining 5% assigned towards a liquidation scenario. In addition, this analysis used a 15% lack of marketability discount
given the uncertain timing of the public offering as well as increased volatility in the capital markets. Based on all of these factors, our board of directors determined a fair value of our common
stock to be $3.29 per share.
Allowance for Doubtful Accounts
We assess collectability based on a number of factors, including credit worthiness of the customer along with past transaction history;
in addition, we perform periodic evaluations of our customers' financial condition. Credit losses historically have not been material, which is directly attributable to our subscription-based services
model, enabling us to immediately discontinue the availability of the services in question in the event of non-payment. Through September 30, 2011, we have not experienced any
significant credit losses.
Capitalized Software Costs
Our research and development efforts include both software created for our internal use on behalf of our customers as well as software
elements to be used by our customers in their own facilities. As such, we consider both ASC 350-40 and ASC 985-20 when accounting for our research and development costs.
ASC
350-40,
Internal-Use Software
, contains the following provisions: (1) Preliminary project costs are
expensed as incurred; (2) All costs associated with the development of the application are to be capitalized; and (3) All costs associated with the post-implementation
operation of the software shall be expenses as incurred. As well, the costs for all upgrades and enhancements to the originally developed
69
Table of Contents
software
may be capitalized if additional functionality is added. Accordingly, we capitalize certain software development costs, including the costs to develop new solutions or significant
enhancements to existing solutions, which are developed or obtained for internal use. We capitalize software development costs when application development begins, it is probable that the project will
be completed, and the software will be used as intended. Such capitalized costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is
generally two years. Costs associated with preliminary project stage activities, training, maintenance and all post implementation stage activities are expensed as incurred. To date in 2011, we have
capitalized costs of approximately $0.4 million in aggregate under ASC 350-40. Based on our current plans, we expect to capitalize a similar portion of our development costs in the
future.
ASC
985-20,
Costs of Software to be Sold, Leased, or Marketed,
contains the following provisions: (1) all costs to
establish the technological feasibility shall be expensed when incurred; (2) costs of producing product masters incurred subsequent to establishing technological feasibility shall be
capitalized; and (3) capitalization of computer software costs shall cease when the product is available for general release to customers. Accordingly, software development costs related to
software services to be distributed and sold are capitalized once technological feasibility has been established and prior to the general availability of the solution, with amortization determined for
each individual solution based on the solution's expected economic life. For all development projects subject to this accounting guidance, the costs to establish technological feasibility have been
expensed as incurred. To date, all costs subsequent to technological feasibility but prior to general availability have not been material and as such we have not capitalized any costs associated with
projects subject to ASC 985-20. All costs subsequent to general availability have been expensed as incurred.
Impairment of Long Lived Assets
In accordance with ASC 360,
Property, Plant, and Equipment
, we evaluate
long-lived assets, such as property and equipment and intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying value of
an asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate.
If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. No assets were determined to
be impaired to date.
Income Taxes
We account for income taxes under ASC 740,
Income Taxes
. Under ASC 740, deferred tax
assets and liabilities are determined based on the differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates that will be in
effect when the differences are expected to reverse. A valuation allowance is established to reduce net deferred tax assets to an amount that we estimate is more likely than not to be realized.
We
have elected to use the "with and without" approach as described in ASC 740-20,
Intraperiod Tax Allocation
, in determining
the order in which tax attributes are utilized. As a result, we will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is
realized after all other tax attributes currently available to us have been utilized. In addition, we have elected to account for the impact of stock-based awards on other tax attributes, such as the
research tax credit, through the consolidated statement of operations.
Effective
January 1, 2009, we adopted the accounting guidance for uncertainties in income taxes, which prescribes a recognition threshold and measurement process for recording
uncertain tax positions taken, or expected to be taken in a tax return, in the financial statements. Additionally, the guidance also prescribes new treatment for the de-recognition,
classification, accounting in interim periods and
70
Table of Contents
disclosure
requirements for uncertain tax positions. We accrue for the estimated amount of taxes for uncertain tax positions if it is more likely than not that we would be required to pay such
additional taxes. An uncertain tax position will not be recognized if it has a less than 50% likelihood of being sustained.
We
recognize interest and penalties related to tax positions in income tax expense. To the extent that accrued interest and penalties do not ultimately become payable, amounts accrued
will be reduced and reflected as a reduction of the overall income tax provision in the period that such determination is made. No interest or penalties have been accrued for any period presented.
Recent Accounting Pronouncements
In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amended guidance eliminates one of the
presentation options provided by current U.S. GAAP that is to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, it
gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of
comprehensive income or in two separate but consecutive statements. This guidance will be effective for reporting periods beginning after December 15, 2011 and will be applied retrospectively.
We do not expect that this guidance will have an impact on our financial position, results of operations or cash flows.
In
September 2011, the FASB issued amended guidance relating to the goodwill impairment test. The guidance provides that an entity first assess qualitative factors to determine whether
it is necessary to perform the two-step quantitative goodwill impairment test. Under that option, an entity no longer would be required to calculate the fair value of a reporting unit
unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The guidance also includes examples of the
types of events and circumstances to consider in conducting the qualitative assessment. The guidance will be effective for annual and interim goodwill impairment tests performed for fiscal years
beginning after December 15, 2011. Early adoption is permitted. We are currently evaluating this amended guidance but we do not expect that it will have an impact on our consolidated financial
statements.

BUSINESS
Overview
Proofpoint is a pioneering security-as-a-service vendor that enables large and
mid-sized organizations worldwide to defend, protect, archive and govern their most sensitive data. Our security-as-a-service platform is comprised of
an integrated suite of on-demand data protection solutions, including threat protection, regulatory compliance, archiving and governance, and secure communication. Our solutions are built
on a flexible, cloud-based platform and leverage a number of proprietary technologies, including big data analytics, machine learning, deep content inspection, secure storage and advanced encryption,
to address today's rapidly changing threat landscape.
A
fundamental shift in the sources of cyber crime, from hackers to organized crime and governments, combined with the emergence of international data trafficking, are driving an
unprecedented wave of targeted, malicious attacks designed to steal valuable information. At the same time, the growth of business-to-business collaboration, as well as the consumerization of IT and
the associated adoption of mobile devices and unmanaged Internet-based applications, have proliferated sensitive data and reduced the effectiveness of many existing security products. These factors
have contributed to an increasing number of severe data breaches and expanding regulatory mandates, all of which have accelerated demand for effective data protection and governance solutions.
Our
platform addresses this growing challenge by not only protecting data as it flows into and out of the enterprise via on-premise and cloud-based email, instant messaging, social media
and other web-based applications, but also securely archiving these communications for compliance and discovery. We address four important problems for the
enterprise:
•
Keeping malicious content out;
•
Preventing the theft or inadvertent loss of sensitive information and, in turn, ensuring compliance with regulatory data
protection mandates;
•
Collecting, retaining, governing and discovering sensitive data for compliance and litigation support; and
•
Securely sharing sensitive data with customers, partners and suppliers.
Our
platform and its associated solutions are sold to customers on a subscription basis and can be deployed through our unique cloud-based architecture that leverages both our global
data centers as well as optional points-of-presence behind our customers' firewalls. Our flexible deployment model enables us to deliver superior security and compliance while
maintaining the favorable economics afforded by cloud computing, creating a competitive advantage for us over legacy on-premise and cloud-only offerings.
We
were founded in 2002 to provide a unified solution to help enterprises address their growing data security requirements. Our first solution was commercially released in 2003 to combat
the burgeoning problem of spam and viruses and their impact on corporate email systems. To address the evolving threat landscape and the adoption of communication and collaboration systems beyond
corporate email and networks, we have broadened our solutions to defend against a wide range of threats, protect against outbound security risks, and archive and govern corporate information. Today,
our solutions are used by approximately 2,400 customers worldwide, including 24 of the Fortune 100, protecting tens of millions of end-users. We market and sell our solutions worldwide both directly
through our sales teams and indirectly through a hybrid model where our sales organization actively assists our network of distributors and resellers. We also distribute our solutions through
strategic partners including IBM, Microsoft and VMware.

Industry Background
Significant Shift in the Enterprise Threat Landscape
A number of trends are leading to a significant shift in the nature and severity of data security threats and the measures required to
address them:
•
Data security attacks are becoming more sophisticated and
targeted.
In recent years, data security threats have become more sophisticated as professional criminals, governments and "hacktivists"
have targeted sensitive information and a market has emerged for stolen data. As this transition has happened, threats have shifted away from generic malware and high-volume spam to more
targeted attacks focused on high-value data such as credit card numbers, login credentials, health care records, social security numbers, financial information and intellectual property.
Once stolen, this data often is used in a wide range of illegal activity, including insurance fraud, banking theft, identity theft, credit card fraud and insider trading. Gartner estimates that
through the end of 2015, financially motivated attacks will continue to be the source of more than 70% of the most damaging cyber threats.* Seemingly harmless data such as an email address is also
leveraged in conjunction with personal information from social networking sites to launch targeted "spear phishing" attacks - emails designed to look authentic and trick the
end-user into divulging sensitive data or clicking on a malicious web link to gain access to information protected within corporate networks. Spear phishing attacks are believed to have
been used in a number of recent high profile data breaches.
*
See
"Industry and Market Data."
•
Consumerization of IT and growth of business-to-business collaboration increase risk of data
loss.
The widespread adoption of consumer technologies throughout the enterprise, including mobile devices, unmanaged Internet-based
collaboration and file sharing applications and social networking sites, have caused valuable and sensitive enterprise data to move beyond the reach of traditional corporate data protection measures.
In addition, many companies today operate as part of global, distributed value chains working closely with an extensive network of suppliers, sub-contractors and distribution partners,
with valuable data being constantly exchanged among these business partners. As data increasingly moves beyond traditional network boundaries it becomes more challenging for enterprises to control and
govern.
•
Consequences of data breaches have become more severe.
The
monetary and reputational cost of data breaches, whether malicious or inadvertent, is increasing rapidly. An ongoing wave of high profile breaches in multiple industries has exposed a broad range of
data, including personal information, diplomatic communications, online banking credentials, financial accounts and health care records, causing significant financial and reputational impact to the
affected organizations. A 2011 Ponemon Institute study estimated a 44% increase in successful cyber attacks from the prior year's study contributing to a 56% increase in the median annualized cost of
cyber crime.* In addition, according to Gartner, the federal government estimates there is $5 trillion of intellectual property in the United States, most of it commercially owned, with more
than $300 billion of intellectual property stolen each year from U.S. networks.* Potentially more damaging is the reputational impact to organizations entrusted with sensitive data that is
subsequently compromised.
•
Regulatory mandates create additional data protection and governance
requirements.
Governments around the world and at all levels of jurisdiction are continuing to enact new laws regarding data protection
and privacy as well as new regulations to mandate closer oversight over all aspects of regulatory adherence. Privacy laws and regulations require that enterprises and government organizations create
and enforce policies for the assurance, protection and archiving of various types of corporate information, and the availability of that information in response to litigation
73
Table of Contents
and
other inquiries. For example, laws such as HIPAA, GLBA, the Sarbanes-Oxley Act, related regulations and securities industry oversight requirements have created significant and complex requirements
for the protection and retention of sensitive corporate information. There is also a wide variety of rapidly changing country-specific and even state-specific regulations, such as the UK Data
Protection Act, Canada's Personal Information Protection and Electronic Documents Act (PIPEDA), the European Union's Data Protection Directive and comprehensive privacy regulations enacted in
Massachusetts and Nevada, all of which extend globally to enterprises serving customers in those regions. In addition to government laws and regulations, industry standards such as the Payment Card
Industry Security Standards Council's Data Security Standard (PCI-DSS) mandate that member organizations meet stringent data protection standards.
Traditional information security and compliance solutions are ineffective
To protect their data assets, organizations have typically employed a number of disparate on-premise security products.
However, these solutions are not well suited to addressing today's threats and challenges and many organizations are still unable to adequately protect their data assets for a variety of reasons,
including:
•
Legacy threat protection products are increasingly vulnerable to modern targeted
attacks.
Widely deployed threat protection products, such as firewalls, anti-virus products and secure email gateways were
designed primarily to stop large-scale spam and virus attacks that emerged in the early and mid-2000s. The techniques these systems employ to detect and defend against broad attacks, such
as signature databases of known malicious code, IP-reputation for spam generating sites and "honey pots" or spam-traps to identify new threats, are often ineffective against
today's targeted attacks. Cybercriminals are now employing advanced, targeted attacks such as "spear phishing" designed to defeat these legacy defenses by using URLs and shortened URLs to avoid
signature detection, leveraging compromised accounts to bypass reputation systems, and directly targeting known valid recipients to avoid detection by "honey pots."
•
Siloed, reactive security and compliance offerings provide inadequate data
protection.
To piece together a comprehensive solution for data protection, archiving and governance, enterprises have traditionally
deployed a collection of specialized products and associated hardware for spam and anti-virus protection, compliance enforcement, data loss protection, content encryption, secure mobile
access, archiving and data retention. These point solutions lack the integration and common policy framework to effectively protect and govern data across the enterprise and to ensure a comprehensive
response that coordinates protection against inbound threats with remediation efforts to prevent resulting outbound risks. In addition, existing products are largely reactive, employing either passive
auditing or basic blocking techniques, and do not enable secure communications or proactive data governance in real time. For example, traditional email security offerings will typically deposit even
the most serious of threats in the end-user quarantine, thereby relying on end-users to refrain from opening malicious messages specifically stored in this repository for their review and
disposition by the user.
•
Traditional security architectures assume data is behind corporate
firewalls.
Existing solutions are built on the assumption that sensitive corporate data is stored behind corporate firewalls. With the
consumerization of IT and the associated adoption of mobile devices and cloud-based applications, valuable corporate data is now widely distributed and accessed through a variety of devices. Legacy
systems are unable to provide adequate data protection in this new environment because they are not designed to apply data loss prevention technologies to webmail, Internet-based collaboration
applications or social networking sites.
74
Table of Contents
•
Inflexible, cumbersome security and compliance systems are often bypassed by
end-users.
Traditional security and compliance offerings were designed for IT professionals with limited focus on ease of
use for end-users. Most existing solutions are inflexible, cumbersome to use, and hinder end-users' day-to-day business activities, all of which lead
end-users to bypass them in favor of unsanctioned solutions, thus dramatically increasing the risk of data loss and compliance violations.
•
Discrete, hardware-based offerings have high total cost of
ownership.
Enterprises have traditionally implemented discrete on-premise security, compliance and archiving products that
can be time consuming to deploy and manage, require redundancy and excess capacity to handle peak-level workloads, and are difficult and expensive to upgrade. In addition, traditional
solutions require a wide range of components provided by different vendors with different interfaces and architectures, leading to interoperability issues. This type of patchwork approach is
complicated and expensive to maintain and limits an enterprise's ability to take advantage of the economic and scalability benefits afforded by a
security-as-a-service architecture.
Market opportunity
In an attempt to defend against the constantly evolving threat landscape and to comply with government mandates, enterprises are
beginning to implement new, more robust corporate policies for data protection, archiving and governance. To enforce these new policies, secure communication technologies and policy-based encryption
are being used to limit the leakage of sensitive data and intellectual property, and archiving and eDiscovery solutions are being used to reduce legal compliance risks. According to International Data
Corporation (IDC), a third-party market research company, the total worldwide market for data protection solutions is estimated to grow from $5.2 billion in 2011 to $8.0 billion by 2015,
a CAGR of 11%.*

internally developed applications as well as with those developed by third-parties. In addition, these APIs provide a means to integrate with the other security and compliance components deployed in
our customers' infrastructures.
Our Business Strategy
Our objective is to be the leading security-as-a-service provider of next-generation
data protection and governance solutions. The key elements of our strategy include:
•
Grow our customer base.
We believe the ongoing wave of
data breaches, many of which are instigated by targeted email attacks, is leading more organizations to re-evaluate their legacy threat protection infrastructure. We believe we are
well-positioned to benefit from this replacement cycle. To meet the increasing need among large and mid-sized organizations for effective and comprehensive data protection and
governance, we intend to continue to invest in our direct inside and field sales organizations in order to increase our market share.
•
Broaden the adoption of our platform with existing
customers.
We have designed our security-as-a-service platform as an integrated, modular platform
that enables customers to easily adopt additional services. A majority of our existing customers have licensed only one of our solutions. We believe that this represents a significant opportunity to
expand the adoption of our platform by our existing customers. Accordingly, we plan to invest not only in sales and marketing to drive these sales to existing customers but also in customer service
and research and development to maintain and improve the ongoing customer experience.

Competition
Our markets are highly competitive, fragmented and subject to rapid changes in technology. We compete primarily with a broad array of
data protection and governance software providers.
Key
competitors include:
•
Data protection:
Cisco (through its acquisition of
IronPort), Google (through its acquisition of Postini), McAfee, an Intel subsidiary (through its acquisitions of Secure Computing and MX Logic), Microsoft (through its acquisition of Frontbridge), and
Symantec (through its acquisitions of Brightmail and MessageLabs)
•
Governance:
EMC (through its acquisitions of Legato and
Kazeon), Hewlett-Packard (through its acquisition of Autonomy) and Symantec (through its acquisition of KVS)
86
Table of Contents
We
believe we compete favorably based on the following factors:
•
level of protection against advanced threats;
•
comprehensiveness and integration of the solution;
•
flexibility of delivery models;
•
total cost of ownership;
•
scalability and performance;
•
customer support; and
•
extensibility of platform.
Certain
of our competitors have greater sales, marketing and financial resources, more extensive geographic presence and greater name recognition than we do. We may face future
competition in our markets from other large, established companies, as well as from emerging companies. In addition, we expect that there is likely to be continued consolidation in our industry that
could lead to increased price competition and other forms of competition.
Intellectual Property
We rely on a combination of trade secrets, patents, copyrights and trademarks, as well as contractual protections, to establish and
protect our intellectual property rights and protect our proprietary technology. As of September 30, 2011, we had 15 patents and six patent
applications. We have a number of registered and unregistered trademarks. We require our employees, consultants and other third parties to enter into confidentiality and proprietary rights agreements
and control access to software, documentation and other proprietary information. Although we rely on intellectual property rights, including trade secrets, patents, copyrights and trademarks, as well
as contractual protections to establish and protect our proprietary rights, we believe that factors such as the technological and creative skills of our personnel, creation of new modules, features
and functionality, and frequent enhancements to our solutions are more essential to establishing and maintaining our technology leadership position.
Despite
our efforts to protect our proprietary technology and our intellectual property rights, unauthorized parties may attempt to copy or obtain and use our technology to develop
products with the same functionality as our solution. Policing unauthorized use of our technology and intellectual property rights is difficult.
We
expect that software and other solutions in our industry may be subject to third-party infringement claims as the number of competitors grows and the functionality of products in
different industry segments overlaps. Any of these third parties might make a claim of infringement against us at any time.
Employees
As of September 30, 2011, we employed 348 people, including 153 in sales and marketing, 75 in operations, professional services,
training and customer support, 88 in product development, and 32 in a general and administrative capacity. As of such date, we had 263 employees in the United States and 85 employees internationally.
We also engage a number of temporary employees and consultants. None of our employees is represented by a labor union with respect to his or her employment with us. We have not experienced any work
stoppages and we consider our relations with our employees to be good. Our future success will depend upon our ability to attract and retain qualified personnel. Competition for qualified personnel
remains intense and we may not be successful in retaining our key employees or attracting skilled personnel.

Facilities
Our corporate headquarters, which includes our operations and research and development facilities, is located in Sunnyvale, California,
and consists of 74,338 square feet of space under a lease that expires in 2014. We have an option to extend the lease for three years.
We
have additional U.S. offices in Draper, Utah and Herndon, Virginia. We also lease offices in Toronto, Canada; Paris, France; Tokyo, Japan; Singapore; and Reading, United Kingdom. We
believe our facilities are adequate for our current needs and for the foreseeable future.
We
operate seven data centers at third-party facilities throughout the world: three in the United States, two in Canada, one in The Netherlands and one in Germany.
Legal Proceedings
From time to time, we are involved in various legal proceedings arising from the normal course of business activities. We are not
presently a party to any litigation the outcome of which, we believe, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, operating
results, cash flows or financial condition.
As
part of a pre-IPO due diligence review, we discovered a potential export violation involving the provision of web-based, email communication services to
end-users located in Iran through our Everyone.net service, which we acquired in October 2009. Neither of these suspected end users appears to have been a current customer of these
web-based email services since late 2010 or early 2011. Although we had ceased providing the services, we are making a voluntary submission to OFAC to report this potential violation. In
addition, we determined that after August 2008, we may have shipped a particular hardware appliance model to a limited number of international customers that, prior to shipment, may have required
either a one-time product review or application for an encryption registration number in lieu of such product review. We have since acquired the appropriate encryption registration number.
We are also making a voluntary submission to BIS to report this potential violation. Our investigation of these matters is still ongoing and it is possible that we may discover additional violations.
We are in the process of supplementing our existing systems and procedures designed to ensure that we do not have any such violations in the future. Although we are still in the early stages of
investigating these matters, it is possible these recent voluntary submissions could result in penalties, costs, and restrictions on export privileges, which could harm our operating results.

Table of Contents
Mr. Ward

Capital Partners, one of our largest stockholders.
Our
executive officers are elected by, and serve at the discretion of, our board of directors. There are no familial relationships among our directors and officers.
Board of Directors Composition
Current Board of Directors
Under our bylaws, our board of directors may set the authorized number of directors. Our board of directors currently consists of seven
members.
Pursuant
to the amended and restated voting agreement dated as of February 19, 2008 between our company and the holders of our preferred stock, Messrs. Feiber, Harvey,
Ward, Koen, Steele and Hahn and Ms. Evan have been designated to serve as members of our board of directors. Pursuant to that agreement, Messrs. Feiber and Harvey were selected as
representatives of the holders of our Series A Stock, Ms. Evan was selected as the representative of the holders of our Series B preferred stock, and Mr. Ward was selected
as the representative of the holders of our Series C preferred stock. The current members of our board of directors will continue to serve as directors until their resignations or until their
successors are duly elected by the holders of our common stock, despite the fact that the voting
agreement will terminate upon the closing of this offering. Upon the termination of this agreement, there will be no further contractual obligations regarding the election of our directors.
Classified Board of Directors Following this Offering
Our restated certificate of incorporation and bylaws that will be in effect upon the completion of this offering provide for a
classified board of directors consisting of three classes of directors, each serving staggered three-year terms. Our directors will be divided among the three classes as
follows:
•
Class I directors, whose initial term will expire at the annual meeting of stockholders to be held in 2013;
•
Class II directors, whose initial term will expire at the annual meeting of stockholders to be held in 2014; and
•
Class III directors, whose initial term will expire at the annual meeting of stockholders to be held in 2015.
Directors
in a particular class will be elected for three-year terms at the annual meeting of stockholders in the year in which their terms expire. As a result, only one
class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Each director's
term continues until the election and qualification of his successor, or his earlier death, resignation or removal.
Our
restated certificate of incorporation and bylaws that will be in effect upon the completion of this offering provide that only our board of directors may increase or decrease the
size of our board of directors and fill vacancies on our board of directors until the next annual meeting of stockholders. Any additional directorships resulting from an increase in the authorized
number of directors would be distributed among the three classes so that, as nearly as possible, each class would consist of one-third of the authorized number of directors.
The
classification of our board of directors and provisions described above may have the effect of delaying or preventing a change in control of our company. See "Description of Capital
Stock—Anti-Takeover Provisions—Restated Certificate of Incorporation and Restated Bylaw Provisions."

Director Independence
We have applied to list our common stock on the NASDAQ Global Market. The listing rules of the NASDAQ Global Market require that a
majority of the members of our board of directors be independent. Our board of directors undertook a review of its composition and the independence of each director. Based upon information requested
from and provided by each director concerning his background, employment and affiliations, our board of directors determined that none of our non-employee directors has a relationship that
would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under the rules
of the NASDAQ Global Market. In making this determination, our board of directors considered the relationships that each non-employee director has with our company and all other facts and
circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. The
independence of our board committee members is discussed below.
Board Leadership
Our board of directors is led by our chairman. The chairman of the board chairs all meetings of our board of directors, including
executive sessions. The chairman of the board also acts as liaison between the independent directors and management. We believe that having different people serving in the roles of chairman of the
board and Chief Executive Officer is an appropriate and effective organizational structure for our company at this time. Separating these positions allows our chairman of the board to lead the board
of directors in its fundamental role of providing advice to and independent oversight of management, while enabling our Chief Executive Officer to focus his time on our
day-to-day business. The board of directors further recognizes the commitment required to serve as our chairman, particularly as the board of directors' oversight
responsibilities continue to grow, as well as the time, effort and energy that our Chief Executive Officer is required to devote to his position. However, we also recognize that no single leadership
model is right for all companies at all times, and that depending on the
circumstances, other leadership models, such as having one person serving as both the chairman of the board and Chief Executive Officer, might become appropriate. Accordingly, the board of directors
anticipates periodically reviewing its leadership structure.
Committees of Our Board of Directors
Our board of directors has established an audit committee, a compensation committee and a nominating and governance committee. The
composition and responsibilities of each committee are described below. Members serve on these committees until their resignations or until otherwise determined by our board of directors. Our board of
directors has adopted a charter for each of these committees, which it believes complies with the applicable requirements of current NASDAQ Global Market rules. We intend to comply with future
requirements to the extent they are applicable to us. Following the closing of this offering, copies of the charters for each committee will be available on the investor relations portion of our
website.
Audit Committee
Our audit committee is currently comprised of Ms. Evan, who is the chair of the audit committee, and Mr. Ward. We
anticipate that a third director will be appointed to the audit committee prior to this offering. We believe that the composition of our audit committee prior to this offering, and our audit
committee's charter and functioning will comply with the requirements for independence under current NASDAQ Global Market and SEC rules and regulations. Each member of our audit committee is
financially literate as required by current NASDAQ Global Market listing standards. In addition, our board of directors has determined that Ms. Evan is an audit committee financial expert
within the
93

of Item 407(d) of Regulation S-K under the Securities Act. Our audit committee, among other things:
•
selects a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

than de minimis non-audit services, to be performed by the independent registered public accounting firm; and
•
will review our annual, quarterly and periodic reports related to financial matters to be filed with the SEC.
Compensation Committee
Our compensation committee is currently comprised of Mr. Hahn, who is the chair of the compensation committee, and
Messrs. Feiber and Harvey. The composition of our compensation committee meets the requirements for independence under current NASDAQ rules. Each member of this committee is also a
non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, and an outside director, as defined pursuant
to Section 162(m) of the Code. The purpose of our compensation committee is to discharge the responsibilities of our board of directors relating to compensation of our executive officers. Our
compensation committee, among other things:
•
reviews, approves and determines, or makes recommendations to our board of directors regarding, the compensation of our
executive officers;
•
administers our stock and equity incentive plans;
•
reviews, approves and makes recommendations to our board of directors regarding incentive compensation and equity plans;
•
will review the compensation discussion and analysis to be included in our annual and quarterly reports to be filed with
the SEC and our compensation report to be included in our annual proxy statement; and

94
Table of Contents
Nominating and Governance Committee
The nominating and governance committee will be comprised of two directors. We anticipate that these directors will be appointed to the
nominating and governance committee prior to this offering and the composition of our nominating and governance committee will meet the requirements for independence under current NASDAQ Global Market
rules. Our nominating and governance committee will, among other things:
•
identify, evaluate and select, or makes recommendations to our board of directors regarding, nominees for election to our
board of directors and its committees;
•
evaluate the performance of our board of directors and of individual directors;
•
consider and make recommendations to our board of directors regarding the composition of our board of directors and its
committees;

review related party transactions and proposed waivers of our code of conduct;
•
review developments in corporate governance practices;
•
evaluate the adequacy of our corporate governance practices and reporting; and
•
develop and make recommendations to our board of directors regarding corporate governance guidelines and matters.
The
nominating and corporate governance committee does not have a formal diversity policy in place but will consider diversity of relevant experience, expertise and background, among
other factors, in identifying nominees for directors.
Compensation Committee Interlocks and Insider Participation
During 2010, most of our compensation decisions were made by our compensation committee. No interlocking relationship exists between
our board of directors and the board of directors or compensation committee of any other company, nor has any interlocking relationship existed in the past. None of the members of our compensation
committee has at any time during the prior three years been an officer or employee of ours.
Code of Ethics and Business Conduct
Our board of directors has adopted a code of ethics and business conduct that will become effective upon completion of this offering.
The code of ethics and business conduct will apply to all of our employees, officers and directors. Following the completion of this offering, the full text of our code of ethics and business conduct
will be posted on the investor relations portion of our website at www.proofpoint.com and will be available without charge, upon request in writing to Proofpoint, Inc., 892 Ross Drive,
Sunnyvale, California 94089, Attn: Investor Relations. We intend to disclose future amendments to certain provisions of our codes of ethics and business conduct, or waivers of such provisions, at the
same location on our website identified above and also in public filings.
Director Compensation
Following the closing of this offering, we intend to compensate our non-employee directors with a combination of cash and
equity awards. Non-employee directors will receive an annual retainer fee for service on our board of directors of $30,000, and the additional annual retainer fee for
service:
•
on our audit committee will be $20,000 for the chair of that committee and $10,000 for each of its other members;
95
Table of Contents
•
on our compensation committee will be $12,000 for the chair of that committee and $5,000 for each of its other members;
and
•
on our nominating and corporate governance committee will be $7,500 for the chair of that committee and $3,750 for each of
its other members.
Pursuant
to a policy adopted by our board of directors, each non-employee director who first becomes a member of our board of directors on or after the completion of this
offering will receive an initial option to purchase 75,000 shares of our common stock. At each annual meeting of our stockholders, each non-employee director will automatically be granted
an annual option grant to purchase 25,000 shares of our common stock if the non-employee director has served continuously as a member of our board of directors for at least six months.
Each initial stock option award granted to non-employee directors vests in equal annual installments over three years from the date of grant, the shares underlying which are exercisable at
a price per share equal to the fair market value of the stock on the date of grant. Each annual stock option award vests in full immediately prior to the first annual meeting of our stockholders to
occur after the date of grant. Each of these awards is immediately exercisable in full; however, any unvested shares issued upon exercise will be subject to a right of repurchase by us upon
termination of the director's service at a price per share equal to the fair market value of the stock on the date of grant, which right lapses in accordance with the vesting schedule described above.
The vesting of the awards
made to non-employee directors under the policy described above will accelerate and vest in full in the event of a change in control of our company. The awards will have
10-year terms and will terminate three months following the date the director ceases to be one of our directors or consultants or 12 months following that date if the termination is
due to death or disability. In addition to the awards provided for above, non-employee directors are eligible to receive discretionary awards of stock options. All grants to
non-employee directors will be made on a discretionary basis under the 2012 Equity Incentive Plan.
Non-employee
directors receive no other form of remuneration, perquisites or benefits, but are reimbursed for travel, meal and other expenses incurred to attend meetings. The
following table provides information regarding stock options granted to our non-employee directors during 2010. Each of these options was granted with an exercise price equal to the fair
market value of our common stock on the date of grant and will vest in full 12 months after the date of this prospectus. Other than reimbursement of reasonable travel and related expenses
incurred by non-employee directors in connection with their attendance at meetings of our board of directors and its committees, we did not pay any other fees, make any other equity or
non-equity awards to, or pay any other compensation to our non-employee directors in 2010. All compensation that we paid to Mr. Steele, our only employee director, is
set forth in the tables below under "Executive Compensation—Executive Compensation Tables." No compensation was paid to Mr. Steele in his capacity as a director.

EXECUTIVE COMPENSATION
Compensation Discussion and Analysis
This Compensation Discussion and Analysis provides an overview of the material components of our executive compensation program for:
•
Gary Steele, our Chief Executive Officer (our "CEO");
•
Paul Auvil, our Chief Financial Officer (our "CFO");
•
Wade Chambers, our Executive Vice President, Engineering;
•
Tom Cooper, our Executive Vice President, Worldwide Field Operations; and
•
Dean Hickman-Smith, our Senior Vice President, Worldwide Sales.
We
refer to these executive officers collectively in this Compensation Discussion and Analysis and the related compensation tables as the "Named Executive Officers."
Specifically,
this Compensation Discussion and Analysis provides an overview of our executive compensation philosophy, the overall objectives of our executive compensation program, and
each component of compensation that we provide. In addition, we explain how and why the compensation committee of our board of directors arrived at the specific compensation policies and decisions
involving our executive officers, including the Named Executive Officers listed in the Summary Compensation Table set forth below, during 2010.
Executive Compensation Philosophy and Objectives
We operate in a highly competitive business environment, which is characterized by frequent technological advances, rapidly changing
market requirements, and the emergence of new market entrants. To successfully grow our business in this dynamic environment, we must continually develop and refine our solutions to stay ahead of
customer needs and challenges. To achieve these objectives, we need a highly talented and seasoned team of technical, sales, marketing, operations, and other business professionals.
We
compete with many other companies in seeking to attract and retain a skilled management team. To meet this challenge, we have embraced a compensation philosophy of offering our
executive officers a competitive total compensation program that recognizes and rewards individual performance and contributions to our success, allowing us to attract, retain, and motivate talented
executives with the skills and abilities needed to drive our desired business results.
The
specific objectives of our executive compensation program are to:
•
reward the successful achievement of our financial growth objectives;
•
drive the development of a successful and profitable business;
•
attract, motivate, reward, and retain highly-qualified executives who are important to our success; and
•
recognize strong performers by offering compensation that rewards individual achievement as well as contributions to our
overall success.
Compensation Program Design
Our executive compensation consists of base salary, an annual cash bonus opportunity, sales commissions plans, equity compensation in
the form of stock options, and certain employee welfare benefits.
97
Table of Contents
Historically,
the key component of our executive compensation program has been equity awards for shares of our common stock. As a privately-held company, we have emphasized
the use of equity to provide incentives for our executive officers to focus on the growth of our overall enterprise value and, correspondingly, to create value for our stockholders. We have used stock
options as our primary equity award vehicle for all of our employees. We believe that stock options offer our employees, including the Named Executive Officers, a valuable long-term
incentive that aligns their interests with the long-term interests of our stockholders. Going forward, we may introduce other forms of stock-based compensation awards, as we deem
appropriate, into our executive compensation program to offer our executive officers additional types of long-term equity incentives that further this objective.
We
also offer cash compensation in the form of base salaries, annual cash bonus opportunities and sales commissions. Typically, we have structured our annual cash bonus opportunities to
focus on the achievement of specific short-term financial and strategic objectives that will further our longer-term growth objectives.
Historically,
we have used standard industry surveys, including the Radford High-Technology Executive Compensation Survey, particularly for companies with annual revenue of
up to $200 million, to assist the compensation committee in establishing cash compensation levels for our executive officers with an emphasis on technology companies with a similar size, stage
of development, and growth potential. Using this information as a guideline, the compensation committee has emphasized remaining competitive in our market and differentiating total cash compensation
levels through the use of an annual cash bonus plan and sales commissions. Equity compensation has been delivered on a discretionary basis with the goal to retain top talent and align the interests of
our executive officers with the long-term interests of our stockholders.
We
have not adopted any formal policies or guidelines for allocating compensation between current and long-term compensation, between cash and non-cash
compensation, or among different forms of non-cash compensation. Instead, the compensation committee reviews each component of executive compensation separately and also takes into
consideration the value of each executive officer's compensation package as a whole and its relative size in comparison to our other executive officers.
Compensation-Setting Process
Role of the Compensation Committee
Since 2004, the compensation committee has been responsible for evaluating, approving, and reviewing the compensation arrangements,
plans, policies, and programs for our executive officers, including the Named Executive Officers (other than our CEO), and directors, and overseeing our cash-based and equity-based
compensation plans. Generally, decisions with respect to the cash compensation of our executive officers have been made by the compensation committee, while decisions with respect to their equity
compensation awards have been made by our board of directors, based upon the recommendations of the compensation committee. In the case of our CEO's equity compensation awards, decisions have been
made by the independent members of our board of directors.
At
the beginning of each year, the compensation committee, after consulting with management, establishes the corporate performance objectives for our company and makes decisions with
respect to any base salary adjustment, approves certain individual performance objectives and target annual cash bonus opportunities and formulates recommendations with respect to equity awards for
our executive officers, including the Named Executive Officers, for the upcoming year. Any recommendations for equity awards to our executive officers are submitted to our board of directors for its
consideration and approval. After the end of the fiscal year, the compensation committee reviews the performance of our
98
Table of Contents
executive
officers, including the Named Executive Officers, to determine the payouts for the annual cash bonus opportunities for the previous year.
The
compensation committee reviews on a periodic basis, at least annually, our executive compensation program, including any incentive compensation plans, to determine whether they are
appropriate, properly coordinated, and achieve their intended purposes and recommends to our board of directors any modifications or new plans or arrangements.
Role of Management
In carrying out its responsibilities, the compensation committee works with members of our management, including our CEO. Typically,
our management assists the compensation committee by providing information on corporate and individual performance, market data, and management's perspective and recommendations on compensation
matters. This information has included an analysis of the compensation mix and levels of our executive officers compared to the competitive market (as determined using compensation survey data)
prepared by our Human Resources Department. The compensation committee then uses this information as reference points in its deliberations on specific compensation actions and decisions.
Historically,
the initial compensation arrangements with our executive officers, including the Named Executive Officers, have been determined in negotiations with each individual
executive. Our CEO has been responsible for negotiating these arrangements, with the oversight and final approval of the compensation committee (except for Mr. Cooper's initial compensation
arrangement, which was negotiated and approved by the compensation committee).
Typically,
our CEO will make recommendations to the compensation committee regarding compensation matters, including the compensation of our executive officers (except with respect to
his own compensation). Historically, these recommendations have been based on a review of competitive market data as prepared by our Human Resources Department and his evaluation of each executive
officer's individual performance. He also attends compensation committee meetings, except with respect to discussions involving his own compensation. Further, he recuses himself from meetings of our
board of directors when they engage in deliberations with respect to his equity compensation awards.
While
the compensation committee solicits and reviews our CEO's recommendations and proposals with respect to compensation-related matters, the compensation committee only uses these
recommendations and proposals as one factor in making compensation decisions.
Role of Compensation Consultant
The compensation committee is authorized to retain the services of one or more executive compensation advisors from time to time, as it
sees fit, in connection with carrying out its duties.
Beginning
in 2010, the compensation committee engaged Compensia, Inc., a national compensation consulting firm that provides executive compensation advisory services, to assist it
in administering our executive compensation program. In addition, as we have begun the transition to public company status, Compensia has assisted the compensation committee in evaluating various
alternatives for our equity compensation strategies and funding, and various other aspects of our executive compensation program. In the future, we expect that the compensation committee, as part of
its annual review of our executive officers' compensation, will instruct its executive compensation advisor to perform an analysis of our executive compensation program to ensure alignment with our
compensation strategy and competitive market practices. Compensia serves at the discretion of the compensation committee.

Use of Competitive Data
To assess the competitiveness of our executive compensation program and current compensation levels and to assist it in setting
compensation levels, historically the compensation committee referred to standard industry surveys, including the Radford High-Technology Executive Compensation Survey. While the
compensation committee reviewed this compensation data to inform its decision-making process, it did not set compensation components to meet specific benchmarks. Instead, the compensation committee
used this data as a point of reference so that it could set total compensation levels that it believed were reasonably competitive. While compensation levels differed among our executive officers
based on competitive factors, and the role, responsibilities, and performance of each specific executive officer, there were not material differences in the compensation policies and practices for our
executive officers, including the Named Executive Officers.
During
2011, the compensation committee, assisted by our management and Compensia, began to develop a compensation peer group comprised of comparably-sized publicly-held
companies, taking into consideration size and growth potential, to be used as a reference source in connection with future executive compensation deliberations. This compensation peer group, which
consisted of both technology companies that had conducted an initial public offering of their equity securities within the past several years and similarly-sized companies in the same industry sector,
was used by the compensation committee for reference purposes during its compensation deliberations during 2011.
This
peer group is comprised of the following companies:
Actuate Corporation
LivePerson, Inc.
BroadSoft, Inc.
LogMeIn, Inc.
comScore, Inc.
Smith Micro Software, Inc.
Constant Contact, Inc.
SolarWinds, Inc.
DemandTec, Inc.
Sourcefire, Inc.
Envestnet, Inc.
SuccessFactors, Inc.
Fortinet, Inc.
TeleNav, Inc.
IntraLinks Holdings, Inc.
VASCO Data Security International, Inc.
KIT digital, Inc.
Vocus, Inc.
Executive Compensation Program Components
The following describes each component of our executive compensation program, the rationale for each, and how compensation amounts and
awards are determined.
Base Salary
Base salary is the primary fixed component of our executive compensation program. We use base salary to compensate our executive
officers, including the Named Executive Officers, for services rendered during the year, and to ensure that we remain competitive in attracting and retaining executive talent. The compensation
committee conducts an annual review of each
executive officer's base salary and makes adjustments as it determines to be reasonable and necessary to reflect the scope of an executive officer's performance, contributions, responsibilities,
experience, prior salary level and position (in the case of a promotion), and market conditions.
In
February 2010, the compensation committee reviewed the base salaries of our executive officers, including the Named Executive Officers, taking into consideration a compensation
analysis performed
100
Table of Contents
by
our Human Resources Department and the base salary recommendations of our CEO (except with respect to his own base salary), as well as the other factors described above. Exercising its judgment and
discretion, the compensation committee determined to make adjustments to the annual base salaries of certain of our executive officers that ranged from 0% to 28%. The compensation committee did not
benchmark the base salaries of our executive officers against any specific companies or compensation surveys, but did take into account data from the Radford High-Technology Executive
Compensation Survey and data from Compensia in making these subjective determinations. The compensation committee determined that such adjustments were necessary and appropriate to maintain the fixed
component of our executive officers' compensation at competitive levels.
The
adjustments to the base salaries of the Named Executive Officers for 2010 were as follows:
Named Executive Officer
2009 Base Salary
Percentage Increase
2010 Base Salary
Mr. Steele
$
235,000

Mr. Hickman-Smith

These
base salary adjustments were effective on March 1, 2010. Mr. Steele's base salary was increased in order to bring his base salary from below the
25
th
percentile to the 75
th
percentile of the compensation data from the Radford survey and data from Compensia. Mr. Auvil's base salary was increased
to bring his salary from below the 25
th
percentile of the compensation data from the Radford survey and data from Compensia as well as recently-public companies to approximately
the 50
th
percentile.
Mr. Cooper's
annual base salary was set at $250,000 when he joined our company on December 6, 2010. This amount was determined based on arms-length negotiations
between Mr. Cooper and the compensation committee in establishing his employment relationship with us.
The
base salaries paid to the Named Executive Officers during 2010 are set forth in the Summary Compensation Table below.
Annual Cash Bonuses
We use cash bonuses to motivate our executive officers, including the Named Executive Officers, to achieve our annual financial and
operational objectives, while making progress towards our longer-term growth and other goals. Generally, the compensation committee pays bonuses to our executive officers in its discretion
after the end of the year based on its evaluation of the achievement of one or more corporate performance measures established in our annual operating plan and individual performance requirements, as
described further below.
At
the beginning of each year, the compensation committee adopts an annual bonus plan for our management team and selects one or more corporate financial and operational measures for use
in determining the target size of the bonus pool for the year from which bonuses will be paid. In addition, with respect to our executive officers, including the Named Executive Officers, the
compensation committee also establishes target bonus opportunities for each executive officer and determines the individual performance objectives for variable compensation for certain executive
officers.
In
February 2010, the compensation committee approved our Executive Bonus Plan for purposes of providing bonus opportunities to our management team, including the Named Executive
Officers.
2010 Target Bonus Opportunities
Under the Executive Bonus Plan, the target bonus opportunities were designed to reward our executive officers based on our overall
company performance and the individual executive officer's
101
Table of Contents
contribution
to that performance. As in prior years, the compensation committee determined that the target bonus opportunities for each executive officer should be determined as a percentage of such
executive officer's base salary. The target bonus opportunities for the Named Executive Officers were as follows:
Named Executive Officer
Target Bonus Opportunity
(as a percentage of base salary)
Mr. Steele
50
%
Mr. Auvil
30
Mr. Chambers
30
With
respect to each of the Named Executive Officers listed above, the amount of his target bonus opportunity was established by the compensation committee in consultation with our CEO
(except with respect to his own target bonus opportunity) and was based on several factors, including the scope of the Named Executive Officer's performance, contributions, responsibilities,
experience, prior years' target bonus opportunities and position (in the case of a promotion), and market conditions.
Mr. Cooper's
target bonus opportunity for 2011 was set at $150,000 when he joined our company on December 6, 2010. As with his base salary, this amount was determined based
on arms-length negotiations between Mr. Cooper and the compensation committee in establishing his employment relationship with us.
Mr. Hickman-Smith
did not participate in the Executive Bonus Plan, as his bonus was determined based on the sales commission plan described below.
Corporate Performance Measures
Under the Executive Bonus Plan, the compensation committee selected free cash flow and annual bookings as the two corporate performance
measures that best supported our annual operating plan and enhanced long-term value creation for purposes of funding the bonus pool. For purposes of funding the plan bonus pool, the free
cash flow measure was weighted
25% and the annual bookings measure was weighted 75%. For 2010, the target levels for these two performance measures were set as follows:
Performance Measure
Target Performance Level
Free cash flow
$
(0.2 million)
Annual bookings
80.0 million
The
compensation committee believed that the target levels for these two performance measures for 2010 would require a focused effort by management to generate the target funding for the
bonus pool associated with these measures. The Executive Bonus Plan provided that the bonus pool would receive minimum funding at 50% of the target funding level established for the annual bookings
measure if we achieved at least 90% of our annual bookings target for the year (on a weighted value basis, this amount would represent 37.5% of the potential funding of the bonus pool). Between 90%
and 100% achievement of our annual bookings target for the year, the funding of the bonus pool would increase by 5% for each 1% of performance. Finally, above our annual bookings target for the year,
the funding of the bonus pool would increase by 25% for each 2.5% of performance up to a maximum funding of 250% if we achieved 115% of our annual bookings target.
The
Executive Bonus Plan also provided that, in the event that we achieved 90% of our annual bookings target for the year, the bonus pool would receive funding of an additional 25% of
the target funding level for the overall bonus pool if we achieved our free cash flow target for the year. A failure to achieve this target level would result in no funding of the bonus pool with
respect to this measure.
102
Table of Contents
Individual Performance Measures
Under the Executive Bonus Plan, if we achieved minimum funding of the bonus pool, our CEO was to formulate recommendations on the
amount payable to each executive officer, subject to the approval of the compensation committee. If we achieved at least 90% of our annual bookings target for the year, then the amounts payable would
be based on each participant's actual performance as measured against one or more individual performance objectives.
To
achieve our compensation objective of rewarding individual performance, our CEO developed a series of performance objectives for our executive officers, including the other Named
Executive Officers (other than himself), which he deemed to be integral to the achievement of the corporate performance objectives as well as the strengthening of our internal operations. In addition,
the compensation committee determined the individual performance objectives that would be applicable to our CEO.
For
purposes of the Executive Bonus Plan, these performance objectives for the Named Executive Officers participating in the Executive Bonus Plan were as follows: for Mr. Steele,
his performance objectives related to achieving quarterly revenue goals of $67 million in the aggregate over four quarters, IPO preparedness, obtaining additional cloud-based business, margin
improvements and sales team productivity; for Mr. Auvil, his performance objectives related to timely audit, system integration, implementing internal controls and process initiatives,
continued cost reductions, quarterly cash balance objectives and continuing to improve the forecasting and reporting process; and for Mr. Chambers, his performance objectives related to product
development milestones, cost efficiency and employee attrition.
Further,
our CEO was to evaluate each executive officer's individual contributions towards the achievement of these performance objectives. In the case of our CEO, the compensation
committee would evaluate his individual contributions towards the achievement of his performance objectives.
Award Decisions and Analysis
In February 2011, the compensation committee evaluated our performance during 2010 and determined the amount of the annual cash bonuses
to be paid to our executive officers, including the Named Executive Officers, for 2010. In making these awards, the compensation committee consulted with our CEO with respect to the Named Executive
Officers (except with respect to his own bonus) and evaluated our financial and operational performance and the level of achievement of the corporate performance objectives for the year. The
compensation committee determined that, with respect to the annual bookings measure, we had achieved 96% of our
annual bookings target for the year, and with respect to the free cash flow measure, had exceeded our cash flow target for the same period. Based on these results, the compensation committee then set
the size of the bonus pool to be used to pay cash bonuses under the Executive Bonus Plan at 85% of the target. Therefore, target bonus based on achievement of corporate objectives would be 85% of the
amount of each Named Executive Officers' target bonus.
Our
CEO evaluated the achievement of each executive officer against his individual performance objectives and formulated a recommendation for each such executive officer's annual bonus
for consideration by the compensation committee. These recommendations were based on his subjective assessment of each individual's contributions against the personal performance objectives during the
year. In the case of our CEO, the compensation committee evaluated his performance against his individual performance objectives and determined the amount of his annual bonus. Mr. Steele was
determined to have satisfied his performance objectives at a level of 95%. Mr. Auvil was determined to have satisfied his personal performance objectives at a level of 98%. Mr. Chambers
was determined to have satisfied his personal performance objectives at a level of 90%.

Since
he did not join our company until December 2010, Mr. Cooper was not eligible to receive a cash bonus under the Executive Bonus Plan.
Sales Commission Plan for Mr. Hickman-Smith
As our Senior Vice President, Worldwide Sales, Mr. Hickman-Smith was eligible for a commission plan providing for the
opportunity to receive incentive compensation based on the ability of our sales organization to achieve specified pre-established sales quotas throughout the year.
For
2010, his target incentive compensation opportunity was equal to 100% of his annual base salary, $225,000. The majority of this target incentive compensation opportunity ($200,000)
was based on the sales organization's actual performance during the year as measured against our monthly, quarterly, and annual bookings quotas for new business, renewals and professional services.
The amounts earned under this portion of his incentive compensation opportunity were to be paid one month in arrears following our determination of the actual bookings for each month. In addition, a
portion of this target annual incentive compensation opportunity ($25,000) was achievable if 50% or more of the representatives in the sales organization achieved 100% of their bookings quotas for the
year. The amounts paid under this incentive award opportunity are paid on an annual basis. In addition to his target incentive compensation, Mr. Hickman-Smith was eligible to receive an annual
revenue bonus of
$25,000, payable upon meeting the specified revenue targets for the first half and second half of the year.
We
have not disclosed the specific target levels for sales commission quotas because we believe that such disclosure would result in competitive harm to our company. The specific target
levels were based on our historical operating results and growth rates, as well as our expected future results, and were designed to require significant effort on the part of Mr. Hickman-Smith.
Mr. Hickman-Smith
earned sales commissions of $182,873 during 2010. Mr. Hickman-Smith did not receive the bonus associated with the sales force productivity.
The
cash bonuses paid to the Named Executive Officers for 2010 are set forth in the Summary Compensation Table below.
Equity Compensation
We use equity awards to incentivize and reward our executives officers, including the Named Executive Officers, for
long-term corporate performance based on the value of our common stock and, thereby, to align the interests of our executive officers with those of our stockholders. These equity awards
have been granted in the form of stock options to purchase shares of our common stock. We believe that stock options, when granted with exercise prices equal to the fair market value of our common
stock on the date of grant, provide an appropriate long-term incentive for our executive officers, since the stock options reward them only to the extent that our stock price grows and
stockholders realize value following their grant date.
Typically,
we have granted stock options to our executive officers, including the Named Executive Officers, as part of the compensation committee's annual review of executive
compensation. To date,
104
Table of Contents
the
compensation committee has not applied a rigid formula in determining the size of these equity awards. Instead, the compensation committee formulates an equity award recommendation for each
executive officer after taking into consideration a compensation analysis performed by our Human Resources Department, the equity award recommendations of our CEO (except with respect to his own
award), the scope of an executive officer's performance, contributions, responsibilities and experience, and the amount of equity compensation held by the executive officer (including the current
economic value of his unvested equity and the ability of these unvested holdings to satisfy our retention objectives, market conditions, and internal equity). These recommendations are then submitted
to our
board of directors for approval. In making its award decisions, our board of directors exercises its judgment and discretion to set the size of each award at a level it considers appropriate to create
a meaningful opportunity for reward predicated on the creation of long-term stockholder value.
On
February 11, 2010, the compensation committee approved recommendations for stock option grants for each of our executive officers, including the Named Executive Officers, in
recognition of our financial results and each executive officer's individual performance for 2009. These recommendations then were submitted to our board of directors for review and consideration. On
March 9, 2010, our board of directors approved stock option grants for each of our executive officers, including the Named Executive Officers. In the case of our CEO, the independent members of
our board of directors approved his stock option grant. The size of these stock option grants was determined by the compensation committee based on its evaluation of the compensation analysis prepared
by our Human Resources Department, its subjective assessment of the performance of each of our executive officers, and its motivation and retention objectives for each of our executive officers. These
stock options were granted with an exercise price equal to $1.94 per share, the fair market value of our common stock as determined by our board of directors on that date. The stock option grants made
to the Named Executive Officers were as follows:
Named Executive Officer
Number of Shares Underlying
Stock Option Grant
Mr. Steele
735,269
Mr. Auvil
400,000
Mr. Chambers
100,000
Mr. Hickman-Smith

In
December 2010, in connection with his joining us as our Executive Vice President, Worldwide Field Operations, the compensation committee recommended, and our board of directors
approved, the grant to Mr. Cooper of a stock option to purchase 1,263,029 shares of our common stock with an exercise price equal to $2.69 per share. This stock option grant is discussed in
more detail below.
The
equity awards granted to the Named Executive Officers during 2010 are set forth in the Summary Compensation Table and the Grants of Plan-Based Awards Table below.
Welfare and Other Benefits
We have established a tax-qualified Section 401(k) retirement plan for all employees who satisfy certain eligibility
requirements, including requirements relating to age and length of service. We currently do not match any contributions made to the plan by our employees, including executive officers. We intend for
the plan to qualify under Section 401(a) of the Internal Revenue Code so that contributions by employees to the plan, and income earned on plan contributions, are not taxable to employees until
withdrawn from the plan.
In
addition, we provide other benefits to our executive officers, including the Named Executive Officers, on the same basis as all of our full-time employees in the country
in which they are resident. These benefits include medical, dental, and vision benefits, medical and dependent care flexible spending accounts, short-term and long-term
disability insurance, accidental death and dismemberment insurance, and basic life insurance coverage.
105
Table of Contents
We design our employee benefits programs to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We
adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.
Currently,
we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites to our
executive officers, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and
effective, and for recruitment and retention purposes.
In
the future, we may provide perquisites or other personal benefits in limited circumstances, such as where we believe it is appropriate to assist an individual executive officer in the
performance of his or her duties, to make our executive officers more efficient and effective, and for recruitment, motivation, or retention purposes. All future practices with respect to perquisites
or other personal benefits will be approved and subject to periodic review by the compensation committee.
Employment Agreements
We have entered into employment agreements with each of our executive officers, except as described below, which are comprised of an
offer letter, the Proprietary Information and Inventions Agreement, and the Arbitration Agreement. Our employment agreement with Mr. Steele is comprised solely of an offer letter and the
Employee Confidentiality Agreement. The initial terms and conditions of employment of each of the Named Executive Officers are set forth in a written employment offer letter with such individual. Each
of these arrangements was approved on our behalf by our board of directors or, in certain instances, the compensation committee. We believe that these employment offer letters were necessary to induce
these individuals to forego other employment opportunities or leave their current employer for the uncertainty of a demanding position in a new and unfamiliar organization.
In
filling these executive positions, our board of directors and the compensation committee, as applicable, was aware that it would be necessary to recruit candidates with the requisite
experience and skills to manage a growing business in a unique market niche. Accordingly, it recognized that it would need to develop competitive compensation packages to attract qualified candidates
in a dynamic labor market. At the same time, our board of directors and the compensation committee was sensitive to the need to integrate new executive officers into the executive compensation
structure that it was seeking to develop, balancing both competitive and internal equity considerations.
Each
of these employment offer letters provided for "at will" employment and sets forth the initial compensation arrangements for the executive officer, including an initial base salary,
an annual cash bonus opportunity and/or a commissions plan, and an equity award in the form of a stock option to purchase shares of our common stock. Certain of the employment offer letters contain
certain qualifying termination and change in control benefits in favor of certain Named Executive Officers. These arrangements provide for payments and benefits upon termination of their employment in
specified circumstances, including following a change in control. These arrangements (including potential payments and terms) are discussed in more detail in "—Offer Letters and
Arrangements" and "—Potential Payments upon Termination or Change in Control" sections below.
Outstanding Stock Options
Except as described below in "Offer Letters and Arrangements," in the event that the employment of an executive officer is
involuntarily terminated within 18 months following a change in control of our company for executive officers who have worked for our company one year or more prior to involuntary termination,
the unvested shares of our common stock subject to all of the outstanding
106
Table of Contents
stock
options previously granted to such executive officer will become immediately vested and exercisable in full, as described in "—Potential Payments Upon Termination or Change in
Control."
Objectives of Protections
We believe that these protections assisted us in attracting these individuals to join our company. We also believe that these
protections serve our executive retention objectives by helping the Named Executive Officers maintain continued focus and dedication to their responsibilities to maximize stockholder value, including
in the event that there is a potential transaction that could involve a change in control of our company. The terms of these agreements were determined after review by our board of directors or the
compensation committee, as applicable, of our retention goals for each executive officer and an analysis of relevant market data.
For
a summary of the material terms and conditions of these severance and change in control arrangements, see "Potential Payments Upon Termination or Change in Control" below.
Other Compensation Policies
Stock Ownership Guidelines
Currently, we have not implemented a policy regarding minimum stock ownership requirements for our executive officers, including the
Named Executive Officers.
Compensation Recovery Policy
Currently, we have not implemented a policy regarding retroactive adjustments to any cash or equity-based incentive compensation paid
to our executive officers and other employees where the payments were predicated upon the achievement of financial results that were subsequently the subject of a financial restatement. We intend to
adopt a general compensation recovery (clawback) policy covering our annual and long-term incentive award plans and arrangements once we are a publicly-traded company and after the SEC
adopts final rules implementing the requirement of Section 954 of the Dodd-Frank Act.
Derivatives Trading and Hedging Policy
Currently, we have not implemented a policy regarding the trading of derivatives or the hedging of our equity securities by our
employees, including the Named Executive Officers, and directors.
Tax and Accounting Considerations
Deductibility of Executive Compensation
Section 162(m) of the Internal Revenue Code generally disallows public companies a tax deduction for federal income tax purposes
of remuneration in excess of $1 million paid to the chief executive officer and each of the three other most highly-compensated executive officers (other than the chief financial officer) in
any taxable year. Generally, remuneration in excess of $1 million may only be deducted if it is "performance-based compensation" within the meaning of the Code. In this regard, the compensation
income realized upon the exercise of stock options granted under a stockholder-approved stock option plan generally will be deductible so long as the options are granted by a committee whose members
are non-employee directors and certain other conditions are satisfied.
As
we are not currently publicly-traded, our board of directors has not previously taken the deductibility limit imposed by Section 162(m) into consideration in setting
compensation for our executive officers. We expect that, where reasonably practicable, the compensation committee will seek to qualify the variable compensation paid to our executive officers for the
"performance-based
107
Table of Contents
compensation"
exemption from the deductibility limit. As such, in approving the amount and form of compensation for our executive officers in the future, we will consider all elements of the cost to
our company of providing such compensation, including the potential impact of Section 162(m). In the future, the compensation committee may, in its judgment, authorize compensation payments
that do not comply with an exemption from the deductibility limit when it believes that such payments are appropriate to attract and retain executive talent.
Taxation of "Parachute" Payments
Sections 280G and 4999 of the Internal Revenue Code provide that executive officers and directors who hold significant equity
interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of our company that exceeds
certain prescribed limits, and that our company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We did not provide any executive officer, including any Named
Executive Officer, with a "gross-up" or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or
4999 during 2010, and we have not agreed and are not otherwise obligated to provide any executive officer with such a "gross-up" or other reimbursement.
Accounting for Stock-Based Compensation
We follow ASC 718 for our stock-based compensation awards. ASC 718 requires companies to measure the compensation expense for all
share-based payment awards made to employees and directors, including stock options, based on the grant date "fair value" of these awards. This calculation is performed for accounting purposes and
reported in the compensation tables below, even though our executive officers may never realize any value from their awards. ASC 718 also requires companies to recognize the compensation cost of their
stock-based compensation awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award.
Compensation Risk Assessment
As part of its oversight of our compensation programs, our compensation committee has considered our executive officer and
non-executive employee compensation programs as they relate to corporate risk management. Our compensation programs are currently consistent with practices of other companies in our
industry, and our compensation committee has concluded that our compensation policies and practices are not likely to have a material adverse effect on us, including for the following
reasons:
•
the compensation committee's retention of a high degree of discretion with respect to our management incentive
compensation plan, as well as our use of multiple performance objectives in that plan and our use of a single incentive compensation plan in which the entire management team participates, together
minimize the risk that might be posed by the short-term variable component of our compensation program; and
•
the long-term component of our compensation program, which to date has consisted of stock options, keeps our
officers and employees appropriately focused on long-term entity-level growth through multi-year vesting schedules and by conveying value only if we succeed in growing our
business in a way that results in appreciation of the value of our common stock over time.

Change in Control Arrangements
Our stock option agreements for each of our Named Executive Officers generally provide for acceleration of vesting of 100% of the
unvested shares underlying their options in the event of an involuntary termination (as such term is defined in the stock option agreement) within 18 months following a change in control in our
company for employees who have worked for our company for one year or more prior to the involuntary termination. In the case of an involuntary termination (as such term is defined in
Mr. Cooper's stock option agreement), Mr. Cooper's options would accelerate as provided for under "—Offer Letters and Arrangements" and "—Grants of Plan-Based
Awards." The following table summarizes the value of this
acceleration to these Named Executive Officers pursuant to these awards, assuming an involuntary termination and change in control as of December 31, 2010. Values are based upon the value of a
share of our common stock as of December 31, 2010, which we assumed to be the midpoint of the price range set forth on the cover page of this prospectus, minus the exercise price.

Employee Benefit Plans
2002 Stock Option/Stock Issuance Plan
Our board of directors adopted our 2002 Stock Option/Stock Issuance Plan in December 2002. Our 2002 Stock Option/Stock Issuance Plan
was also approved by our stockholders. The 2002 Stock Option/Stock Issuance Plan provides for the grant of both incentive stock options, which qualify for favorable tax treatment to their recipients
under Section 422 of the Code, and nonstatutory stock options, as well as for the issuance of shares of restricted stock. We may grant incentive stock options only to our employees. We may
grant nonstatutory stock options to our employees, directors and consultants. The exercise price of each incentive stock option must be at least equal to the fair market value of our common stock on
the date of grant and the exercise price of each nonstatutory stock option must be at least equal to 85% of the fair market value of our common stock on the date of
113
Table of Contents
grant.
The exercise price of incentive stock options granted to 10% stockholders must be at least equal to 110% of the fair market value of our common stock on the date of grant. The maximum permitted
term of options granted under our 2002 Stock Option/Stock Issuance Plan is ten years. In the event of a "change in control," as defined in the 2002 Stock Option/Stock Issuance Plan, the 2002 Stock
Option/Stock Issuance Plan provides that, unless the applicable option agreement provides otherwise, options held by current employees, directors and consultants will terminate if not assumed or
substituted with no acceleration of vesting.
As
of September 30, 2011, we had reserved 28,555,342 shares of our common stock for issuance under our 2002 Stock Option/Stock Issuance Plan. As of September 30, 2011,
options to purchase 7,088,122 of these shares had been exercised, options to purchase 20,227,426 of these shares remained outstanding and 1,557,769 of these shares remained available for future grant.
The options outstanding as of September 30, 2011 had a weighted-average exercise price of $1.73. Our 2012 Equity Incentive Plan will be effective upon the date of this prospectus. As a result,
we will not grant any additional options under the 2002 Stock Option/Stock Issuance Plan following that date and the 2002 Stock Option/Stock Issuance Plan will terminate at that time. However, any
outstanding options granted under the 2002 Stock Option/Stock Issuance Plan will remain outstanding, subject to the terms of our 2002 Stock Option/Stock Issuance Plan and stock option agreements,
until such outstanding options are exercised or until they terminate or expire by their terms. Options granted under the 2002 Stock Option/Stock Issuance Plan generally have terms similar to those
described below with respect to options granted under our 2012 Equity Incentive Plan, except that stock option agreements evidencing options granted to employees under our 2002 Stock Option/Stock
Issuance Plan generally provide for partial acceleration of vesting in connection with a change in control followed by the optionee's involuntary termination.
2012 Equity Incentive Plan
We anticipate that we will adopt a 2012 Equity Incentive Plan that will become effective on the date of this prospectus and will serve
as the successor to our earlier stock plans. We anticipate that we will reserve            shares of our common stock to be issued under our 2012 Equity Incentive Plan. We also anticipate
that
the number of shares reserved for issuance under our 2012 Equity Incentive Plan will increase automatically on the first day of January of each of 2013 through 2016 by the number of shares equal to
        % of the total outstanding shares of our common stock as of the immediately preceding December 31, but not more than            shares.
However, our board of directors or
compensation committee may reduce the amount of the increase in any particular year. In addition, the following shares will again be available for grant and issuance under our 2012 Equity Incentive
Plan:
•
shares subject to options or stock appreciation rights granted under our 2012 Equity Incentive Plan that cease to be
subject to the option or stock appreciation right for any reason other than exercise of the option;
•
shares subject to awards granted under our 2012 Equity Incentive Plan that are subsequently forfeited or repurchased by us
at the original issue price;
•
shares subject to awards granted under our 2012 Equity Incentive Plan that otherwise terminate without shares being
issued;
•
shares not issued or subject to outstanding grants under our 2002 Stock Option/Stock Issuance Plan on the date of this
prospectus;
•
shares issuable upon the exercise of options under our 2002 Stock Option/Stock Issuance Plan prior to the date of this
prospectus that expire or become unexercisable for any reason without having been exercised in full after the date of this prospectus; and
114
Table of Contents
•
any shares issued under our 2002 Stock Option/Stock Issuance Plan that are forfeited or repurchased by us after the date
of this prospectus.
Our
2012 Equity Incentive Plan will authorize the award of stock options, restricted stock awards, stock appreciation rights, restricted stock units, performance awards and stock
bonuses. No person will be eligible to receive more than            shares in any calendar year under our 2012 Equity Incentive Plan other than a new employee of ours, who will be eligible
to
receive no more than            shares under the plan in the calendar year in which the employee commences employment.
Our
2012 Equity Incentive Plan will be administered by our compensation committee, all of the members of which are non-employee directors under applicable federal securities
laws and outside directors as defined under applicable federal tax laws, or by our board of directors acting in place of our compensation committee. The compensation committee will have the authority
to construe and interpret our 2012 Equity Incentive Plan, grant awards and make all other determinations necessary or advisable for the administration of the plan.
We
anticipate that our 2012 Equity Incentive Plan will provide for the grant of incentive stock options that qualify under Section 422 of the Code only to our employees. No more
than            shares may be issued under the 2012 Equity Incentive Plan as incentive stock options. All awards other than incentive stock options may be granted to our employees, directors,

consultants, independent contractors and advisors, provided the consultants, independent contractors and advisors render services not in connection with the offer and sale of securities in a
capital-raising transaction. The exercise price of stock options must be at least equal to the fair market value of our common stock on the date of grant. The exercise price of incentive stock options
granted to 10% stockholders must be at least equal to 110% of that value.
In
general, options will vest over a four-year period. Options may vest based on time or achievement of performance conditions. Our compensation committee may provide for
options to be exercised only as they vest or to be immediately exercisable with any shares issued on exercise being subject to our right of repurchase that lapses as the shares vest. The maximum term
of options granted under our 2012 Equity Incentive Plan is ten years, except that incentive stock options granted to 10% stockholders will have a maximum term of five years.
A
restricted stock award is an offer by us to sell shares of our common stock subject to restrictions. A restricted stock award may vest based on time or achievement of performance
conditions. The price (if any) of a restricted stock award will be determined by the compensation committee. Unless otherwise determined by the compensation committee at the time of award, vesting
will cease on the date the participant no longer provides services to us and unvested shares will be forfeited to us.
Stock
appreciation rights provide for a payment, or payments, in cash or shares of our common stock, to the holder based upon the difference between the fair market value of our common
stock on the date of exercise and the stated exercise price up to a maximum amount of cash or number of shares. Stock appreciation rights may vest based on time or achievement of performance
conditions.
Restricted
stock units represent the right to receive shares of our common stock at a specified date in the future, subject to forfeiture of that right because of termination of
employment or failure to achieve certain performance conditions. If a restricted stock unit has not been forfeited, then on the date specified in the restricted stock unit agreement, we will deliver
to the holder of the restricted stock unit whole shares of our common stock (which may be subject to additional restrictions), cash or a combination of our common stock and cash.
Performance
shares are performance awards that cover a number of shares of our common stock that may be settled upon achievement of the pre-established performance conditions
in cash or by
115
Table of Contents
issuance
of the underlying shares. These awards are subject to forfeiture prior to settlement because of termination of employment or failure to achieve the performance conditions.
Stock
bonuses may be granted as additional compensation for service and/or performance, and therefore, not be issued in exchange for cash.
In
the event there is a specified type of change in our capital structure without our receipt of consideration, such as a stock split, appropriate adjustments will be made to the number
of shares reserved under our 2012 Equity Incentive Plan, the maximum number of shares by which the share reserve may increase automatically each year and the limit on incentive stock options, the
maximum number of shares that can be granted in a calendar year, and the number of shares and exercise price, if applicable, of all outstanding awards under our 2012 Equity Incentive Plan.
Awards
granted under our 2012 Equity Incentive Plan may not be transferred in any manner other than by will or by the laws of descent and distribution or as determined by our
compensation committee. Unless otherwise permitted by our compensation committee, stock options may be exercised during the
lifetime of the optionee only by the optionee or the optionee's guardian or legal representative. Options granted under our 2012 Equity Incentive Plan generally may be exercised for a period of three
months after the termination of the optionee's service to us, or for a period of 12 months in cases of death or disability, or such longer period as our compensation committee may provide.
Options generally terminate immediately upon termination of employment for cause.
If
we are dissolved or liquidated or have a change in control transaction, outstanding awards, including any vesting provisions, may be assumed or substituted by the successor company.
Outstanding awards that are not assumed or substituted will expire upon the dissolution, liquidation or closing of a change in control transaction. In the event of specified change in control
transactions, our compensation committee may accelerate the vesting of awards (a) immediately upon the occurrence of the transaction, whether or not the award is continued, assumed or
substituted by a surviving corporation or its parent in the transaction, or (b) in connection with a termination of a participant's service following such a transaction.
We
anticipate that our 2012 Equity Incentive Plan will terminate ten years from the later of the date our board of directors approves the plan or the date our board of directors adopted
the most recent increase in the number of shares of our common stock available under the plan which was approved by our stockholders, unless it is terminated earlier by our board of directors. Our
board of directors may amend or terminate our 2012 Equity Incentive Plan at any time. If our board of directors amends our 2012 Equity Incentive Plan, it does not need to ask for stockholder approval
of the amendment unless required by applicable law.
2012 Employee Stock Purchase Plan
We anticipate that we will adopt a 2012 Employee Stock Purchase Plan that will become effective on the date of this prospectus which
will be a plan designed to enable eligible employees to purchase shares of our common stock periodically at a discount following the date of this prospectus. Purchases will be accomplished through
participation in discrete purchase periods. Our 2012 Employee Stock Purchase Plan will be intended to qualify as an employee stock purchase plan under Section 423 of the Code. We anticipate we
will initially reserve            shares of our common stock for issuance under our 2012 Employee Stock Purchase Plan. We anticipate that the number of shares reserved for issuance under our
2012
Employee Stock Purchase Plan will increase automatically on the first day of January of each of 2013 through 2019 by the number of shares equal to            % of the total outstanding
shares of
our common stock as of the immediately preceding December 31st (rounded to the nearest whole share), but not more than            shares of our common stock. However, our board of
directors or compensation committee may reduce the amount of the increase in any particular year.
116
Table of Contents
Our
compensation committee will administer our 2012 Employee Stock Purchase Plan. Our employees generally are eligible to participate in our 2012 Employee Stock Purchase Plan if they are
employed by us for at least 20 hours per week and more than five months in a calendar year. Employees who are 5% stockholders, or would become 5% stockholders as a result of their participation
in our 2012 Employee Stock Purchase Plan, are ineligible to participate in our 2012 Employee Stock Purchase Plan. We may impose additional restrictions on eligibility. Under our 2012 Employee Stock
Purchase Plan, eligible employees are able to acquire shares of our common stock by accumulating funds through payroll deductions. Our eligible employees will be able to select a rate of payroll
deduction between 1% and 15% of their cash compensation. We will also have the right to amend or terminate our 2012 Employee Stock Purchase Plan, except that, subject to certain exceptions, no such
action may adversely affect any outstanding rights to purchase stock under the plan. Our 2012 Employee Stock Purchase Plan will terminate on the tenth anniversary of the last day of the first purchase
period, unless it is terminated earlier by our board of directors.
When
an initial purchase period commences, our employees who meet the eligibility requirements for participation in that purchase period will automatically be granted a nontransferable
option to purchase shares in that purchase period. For subsequent purchase periods, new participants will be required to enroll in a timely manner. Once an employee is enrolled, participation will be
automatic in subsequent purchase periods. Each purchase period will run for no more than six months. An employee's participation automatically ends upon termination of employment for any reason.
Except
for the first purchase period, each purchase period will be for six months (commencing each February and August). The first purchase period will begin upon the effective date of
this offering and will end on            , 2012.

participant will have the right to purchase more than 3,000 shares of our common stock in any purchase period, or such smaller number of shares as our compensation committee shall
approve. No participant will have the right to purchase our shares in an amount, when aggregated with purchase rights under all our employee stock purchase plans that are also in effect in the same
calendar year(s), that has a fair market value of more than            , determined as of the first day of the applicable purchase period, for each calendar year in which that right is
outstanding. The purchase price for shares of our common stock purchased under our 2012 Employee Stock Purchase Plan will be 85% of the lesser of the fair market value of our common stock on
(i) the first trading day of the purchase period and (ii) the last trading day of that purchase period.
If
we experience a change in control transaction, the purchase period that commenced prior to the closing of the proposed change in control transaction will be shortened and terminated
on a new purchase date. The new purchase date will occur prior to the closing of the proposed change in control
transaction and our 2012 Employee Stock Purchase Plan will then terminate on the closing of the proposed change in control.
401(k) Plan
We sponsor a retirement plan intended to qualify for favorable tax treatment under Section 401(a) of the Code, containing a cash
or deferred feature that is intended to meet the requirements of Section 401(k) of the Code. Employees who have attained at least 21 years of age are generally eligible to participate in
the plan on the first day of the calendar month following the employees' date of hire. Participants may make pre-tax contributions to the plan from their eligible earnings up to the
statutorily prescribed annual limit on pre-tax contributions under the Code. Participants who are 50 years of age or older may contribute additional amounts based on the statutory
limits for catch-up contributions. Pre-tax contributions by participants that we make to the plan and the income earned on those contributions are generally not taxable to
participants until withdrawn. Employer contributions that we make to the plan are generally deductible when made. Participant contributions are held in
117
Table of Contents
trust
as required by law. No minimum benefit is provided under the plan. An employee's interest in his or her pre-tax deferrals is 100% vested when contributed. Although the plan provides
for a discretionary employer matching contribution, to date we have not made such a contribution on behalf of employees. The Plan permits all eligible Plan participants to contribute between 1% and
50% of eligible compensation, on a pre-tax or after-tax (Roth 401k) basis, into their accounts.
Limitation of Liability and Indemnification of Directors and Officers
Our restated certificate of incorporation and bylaws contains provisions that limit the liability of our directors, officers and
employees for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach
of fiduciary duties as directors, except for liability:
•
for any breach of their duty of loyalty to our company or our stockholders;
•
for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
•
unlawful payments of dividends or unlawful stock purchases or redemptions as provided in Section 174 of the
Delaware General Corporation Law; or
•
for any transaction from which they derived an improper personal benefit.
Any
amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that
amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our
directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.
Our
restated bylaws provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or
proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise. Our restated bylaws provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any
action, suit or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was serving at our request as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. Our restated bylaws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final
disposition of any action or proceeding, subject to very limited exceptions.
Prior
to the closing of this offering, we intend to enter into indemnification agreements with each of our directors and executive officers that may be broader than the specific
indemnification provisions contained in our restated certificate of incorporation and bylaws. These indemnification agreements may require us, among other things, to indemnify our directors and
executive officers against liabilities that may arise by reason of their status as a director, officer or employee or their service to our company. These indemnification agreements may also require us
to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit or proceeding. We believe that these agreements are necessary to attract
and retain qualified individuals to serve as directors and executive officers.
The
limitation of liability and indemnification provisions in our restated certificate of incorporation and restated bylaws or in these indemnification agreements may discourage
stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even
though an action, if successful, might
118
Table of Contents
benefit
us and other stockholders. Further, a stockholder's investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as
required by these indemnification provisions. At present, we are not aware of any pending litigation or proceeding involving any person who is or was one of our directors, officers, employees or other
agents or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, for which indemnification is sought,
and we are not aware of any threatened litigation that may result in claims for indemnification.
We
have obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to our directors and officers against loss arising from claims made by
reason of breach of fiduciary duty or other wrongful acts as a director or officer, including claims relating to public securities matters, and to us with respect to payments that may be made by us to
these officers and directors pursuant to our indemnification obligations or otherwise as a matter of law.
Certain
of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their
capacity as members of our board of directors.
Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling our company pursuant to the foregoing
provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements and
indemnification arrangements, discussed above in the sections entitled "Management" and "Executive Compensation," the registration rights described below under "Description of Capital
Stock—Registration Rights," and the voting rights in our fourth amended and restated voting agreement described above under "Management—Board of Directors Composition," the
following is a description of each transaction since January 1, 2008 and each currently proposed transaction in which:
•
we have been or are to be a participant;
•
the amount involved exceeded or exceeds $120,000; and
•
any of our directors, executive officers or holders of more than 5% of our capital stock, or any immediate family member
of or person sharing the household with any of these individuals, had or will have a direct or indirect material interest.
Stock Option Exchange
In January 2009, our board of directors determined that certain stock options granted to our employees, including our executive
officers, were no longer providing the incentive intended when they were originally granted and the holders of all outstanding, unexercised options, whether vested or unvested, that had exercise
prices per share equal to $2.28 or higher were offered an opportunity to cancel such options in exchange for a new option with an exercise price per share equal to the then current fair market value
per share. In exchange for the lower exercise price per share the new stock options were treated for vesting purposes as if they were granted on the date of the exchange, whether such options were
previously vested or not. The new exercise price per share and revised vesting schedule was designed to incentivize our employees, including our executive officers, to work towards achieving our
long-term financial goals. Two of our executive officers, Mr. Steele and Mr. Hickman-Smith, participated in the stock option exchange. Mr. Steele and
Mr. Hickman-Smith exchanged options convertible into a total of 503,527 and 562,304 shares of our common stock, respectively.
Indemnification Agreements
Prior to the completion of this offering, we plan to enter into indemnification agreements with each of our directors and executive
officers. See "Executive Compensation—Limitation of Liability and Indemnification of Directors and Officers."
Sale of Series F Preferred Stock
In multiple closings between February 2008 and May 2010, we sold an aggregate of 6,461,729 shares of our Series F Preferred
Stock at a purchase price of $5.32 per share for an aggregate purchase price of approximately $34.4 million. Each share of our Series F Preferred Stock will convert automatically into

DESCRIPTION OF CAPITAL STOCK
Upon the closing of this offering and the filing of our restated certificate of incorporation, our authorized capital stock will
consist of                        shares of common stock, $0.0001 par value per share,
and                        shares of undesignated preferred stock, $0.0001 par value per share. The following description
summarizes the most important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should
refer to our restated certificate of incorporation and restated bylaws, which are included as exhibits to the registration statement of which this prospectus forms a part, and to the applicable
provisions of Delaware law.
Assuming
the conversion of all outstanding shares of our preferred stock into shares of our common stock, which will occur immediately upon the completion of this offering, as of
September 30, 2011, there were 47,402,137 shares of our common stock outstanding, held by 231 stockholders of record, and no shares of our preferred stock outstanding. Our board of directors is
authorized, without stockholder approval, to issue additional shares of our capital stock.
Common Stock
Dividend Rights
Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock are
entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of
directors may determine. See "Dividend Policy" above.
Voting Rights
Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. We have
not provided for cumulative voting for the election of directors in our restated certificate of incorporation. Accordingly, holders of a majority of the shares of our common stock will be able to
elect all of our directors. Our restated certificate of incorporation establishes a classified board of directors, to be divided into three classes with staggered three-year terms. Only
one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms.
No Preemptive or Similar Rights
Our common stock is not entitled to preemptive rights, and is not subject to conversion, redemption or sinking fund provisions.
Right to Receive Liquidation Distributions
Upon our liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be
distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and
the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.
Preferred Stock
Following this offering, our board of directors will be authorized, subject to limitations prescribed by Delaware law, to issue
preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences and rights of the shares of
each series and any of its qualifications, limitations or restrictions, in each case
125
Table of Contents
without
further vote or action by our stockholders. Our board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of
that series then outstanding, without any further vote or action by our stockholders. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could
adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other
corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of our company and might adversely affect the market price of our common stock
and the voting and other rights of the holders of our common stock. We have no current plan to issue any shares of preferred stock.
Options
As of September 30, 2011, we had outstanding options to purchase an aggregate of 20,227,426 shares of our common stock, with a
weighted-average exercise price of $1.73.
Warrant
As of September 30, 2011, we had outstanding one warrant to purchase 4,375 shares of our common stock with an exercise price of
$0.15 per share.
Registration Rights
Pursuant to the terms of our fourth amended and restated investors' rights agreement, immediately following this offering, the holders
of approximately 40,541,990 shares of our common stock will be entitled to rights with respect to the registration of these shares under the Securities Act, as described below.
Demand Registration Rights
The holders of at least 50% of the then-outstanding shares having registration rights may make a written request to us for
the registration of the offer and sale of all or part of the shares having registration rights or registrable securities. The holders of at least 25% of the then-outstanding shares may
make the same request at any time after six months after the effective date of our first registration statement, if the amount of registrable securities to be registered has an aggregate market value
of at least $10.0 million. We are only required to file two registration statements that are declared effective upon exercise of these demand registration rights. We may postpone the filing of
a registration statement for up to 90 days in a 12-month period if our board of directors determines that the filing would be seriously detrimental to us and our stockholders.
Piggyback Registration Rights
If we register any of our securities for public sale, holders of shares having registration rights will have the right to include their
shares in the registration statement. However, this right does not apply to a registration relating to sales of shares of participants in one of our stock plans or a registration relating to a
corporate reorganization. The underwriters of any underwritten offering will have the right to limit the number of shares registered by these holders if
they determine in good faith that marketing factors require limitation, in which case the number of shares to be registered will be apportioned pro rata among these holders, according to the total
amount of securities entitled to be included by each holder, or in a manner mutually agreed upon by the holders. However, the number of shares to be registered by these holders cannot be reduced below
25% of the total shares covered by the registration statement.
126
Table of Contents
Form S-3 Registration Rights
The holders of then-outstanding shares having registration rights can request that we register all or part of their shares
on Form S-3 if we are eligible to file a registration statement on Form S-3 and if the aggregate price to the public of the shares offered is at least
$2 million. The stockholders may only require us to effect two registration statements on Form S-3 in a 12-month period. We may postpone the filing of a
registration statement on Form S-3 no more than twice during any 12-month period for a total cumulative period of not more than 90 days if our board of directors
determines that the filing would be detrimental to us and our stockholders.

We generally will pay all expenses, other than underwriting discounts and commissions and the reasonable fees and disbursements of one
counsel for the selling stockholders, incurred in connection with the registrations described above.
Expiration of Registration Rights
The registration rights described above will expire, with respect to any particular holder of these rights, on the earlier of the fifth
anniversary of the closing of this offering or when that holder can sell all of its registrable securities without restriction under Rule 144 of the Securities Act.
Anti-Takeover Provisions
The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws, as we expect they will be in effect
upon the completion of this offering, could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below,
may have the effect of discouraging takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe
that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because
negotiation of these proposals could result in an improvement of their terms.
Delaware Law
We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. In
general, Section 203 prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the
date on which the person became an interested stockholder unless:
•
Prior to the date of the transaction, the board of directors of the corporation approved either the business combination
or the transaction which resulted in the stockholder becoming an interested stockholder;
•
The interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons
who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to
the plan will be tendered in a tender or exchange offer; or
•
At or subsequent to the date of the transaction, the business combination is approved by the board of directors of the
corporation and authorized at an annual or special meeting of
127
Table of Contents
stockholders,
and not by written consent, by the affirmative vote of at least 66.67% of the outstanding voting stock that is not owned by the interested stockholder.
Generally,
a business combination includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder
is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation's outstanding
voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate
that Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.
Restated Certificate of Incorporation and Restated Bylaw Provisions
Our restated certificate of incorporation and our restated bylaws, as we expect they will be in effect upon the completion of this
offering, include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following:
•
Board of Directors Vacancies.
Our restated certificate of
incorporation and restated bylaws will authorize only our board of directors to fill vacant directorships, including newly created seats. In addition, the number of directors constituting our board of
directors is permitted to be set only by a resolution adopted by a majority vote of our entire board of directors. These provisions would prevent a stockholder from increasing the size of our board of
directors and then gaining control of our board of directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our board of directors
but promotes continuity of management.
•
Classified Board.
Our restated certificate of
incorporation and restated bylaws will provide that our board is classified into three classes of directors, each with staggered three year terms. A third party may be discouraged from making a tender
offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors. See
"Management—Board of Directors Composition."
•
Stockholder Action; Special Meetings of Stockholders.
Our
restated certificate of incorporation will provide that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a
result, a holder controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our
amended and restated bylaws. Our restated bylaws further will provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairman of our board of
directors, our Chief Executive Officer or our President, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force
consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.
•
Advance Notice Requirements for Stockholder Proposals and Director
Nominations.
Our restated bylaws will provide advance notice procedures for stockholders seeking to bring business before our annual
meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our restated bylaws also will specify certain requirements regarding the form and
content of a stockholder's notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our
annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also discourage or deter a potential acquirer
128
Table of Contents
from
conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of our company.
•
No Cumulative Voting.
The Delaware General Corporation Law
provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation's certificate of incorporation provides otherwise. Our amended and restated
certificate of incorporation and amended and restated bylaws will not provide for cumulative voting.
•
Directors Removed Only for Cause.
Our restated certificate
of incorporation will provide that stockholders may remove directors only for cause.
•
Amendment of Charter Provisions.
Any amendment of the
above expected provisions in our restated certificate of incorporation would require approval by holders of at least two-thirds of our outstanding common stock.
•
Issuance of Undesignated Preferred Stock.
Our board of
directors has the authority, without further action by the stockholders, to issue up to                        shares of
undesignated preferred stock with rights and preferences, including voting rights,
designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock would enable our board of directors to render more difficult or to discourage
an attempt to obtain control of us by means of a merger, tender offer, proxy contest or other means.
•
Choice of Forum.
Our amended and restated certificate of
incorporation will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach
of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or our bylaws; or any action
asserting a claim against us that is governed by the internal affairs doctrine.
Listing
We intend to apply for the listing of our common stock on the NASDAQ Global Market under the symbol "PFPT."
Transfer Agent and Registrar
The transfer agent and registrar for our common stock will
be                                    . The transfer agent's address
is                                    .

SHARES ELIGIBLE FOR FUTURE SALE
Prior to this offering, there has been no public market for our common stock, and we cannot predict the effect, if any, that market
sales of shares of our common stock or the availability of shares of our common stock for sale will have on the market price of our common stock prevailing from time to time. Nevertheless, sales of
substantial amounts of our common stock, including shares issued upon exercise of outstanding options, in the public market following this offering could adversely affect market prices prevailing from
time to time and could impair our ability to raise capital through the sale of our equity securities.
Upon
the closing of this offering, we will have a total of                        shares of our common stock outstanding, based on the
47,402,137 shares of our capital stock outstanding as of
September 30, 2011. Of these outstanding shares, all of the                        shares of common stock sold in this
offering will be freely tradable, except that any shares purchased in this
offering by our affiliates, as that term is defined in Rule 144 under the Securities Act, would only be able to be sold in compliance with the Rule 144 limitations described below.
The
remaining outstanding shares of our common stock will be deemed "restricted securities" as defined in Rule 144. Restricted securities may be sold in the public market only if
they are registered under the Securities Act or if they qualify for an exemption from registration under Rule 144 or Rule 701 promulgated under the Securities Act, which rules are
summarized below. In addition, all of our security holders have entered into market standoff agreements with us or lock-up agreements with the underwriters under which they have agreed,
subject to specific exceptions, not to sell any of our stock for at least 180 days following the date of this prospectus, as described below. As a result of these agreements and the provisions
of our investors' rights agreement described above under "Description of Capital Stock—Registration Rights," subject to the provisions of Rule 144 or Rule 701, based on an
assumed offering date of                        , 2012, shares will be available for sale in the public market as follows:
•
Beginning on the date of this prospectus, the                        shares
sold in this offering will be immediately available
for sale in the public market;
•
Beginning 181 days after the date of this prospectus, subject to extension as described in "Underwriting" below,
                        additional shares will become eligible for sale in the public market, of
which                        shares will be held by affiliates and subject to the volume and other restrictions of
Rule 144, as described below; and
•
The remainder of the shares will be eligible for sale in the public market from time to time thereafter, subject in some
cases to the volume and other restrictions of Rule 144, as described below.
Lock-Up/Market Standoff Agreements
All of our directors and officers and substantially all of our security holders are subject to lock-up agreements or market
standoff provisions that, subject to exceptions described in the section entitled "Underwriting" below, prohibit them from offering for sale, selling, contracting to sell, granting any option for the
sale of, transferring or otherwise disposing of any shares of our common stock, options to acquire shares of our common stock or any security or instrument related to this common stock, option or
warrant, or entering into any swap, hedge or other arrangement that transfers to another any of the economic consequences of ownership of the common stock, for a period of at least 180 days
following the date of this prospectus without the prior written consent of Credit Suisse Securities
130
Table of Contents
(USA) LLC
and Deutsche Bank Securities Inc. See "Underwriting." The 180-day restricted period described above will be extended if:
•
during the last 17 days of the 180-day restricted period we issue an earnings release or material news
or material event related to us occurs; or
•
prior to the expiration of the 180-day restricted period, we announce that we will release earnings results
during the 16-day period beginning on the last day of the 180-day period, in which case the restrictions described in the preceding paragraph will continue to apply until the
expiration of the 18-day period beginning on the issuance of the release or the occurrence of the material news or material event, unless such extension is waived, in writing by Credit
Suisse Securities (USA) LLC and Deutsche Bank Securities Inc.
Rule 144
In general, under Rule 144 as currently in effect, once we have been subject to public company reporting requirements for at
least 90 days, a person who is not deemed to have been one of our affiliates for purposes of the Securities Act at any time during the 90 days
preceding a sale and who has beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than our affiliates, is entitled to sell
those shares without complying with the manner of sale, volume limitation or notice provisions of Rule 144, subject to compliance with the public information requirements of Rule 144. If
such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of any prior owner other than our affiliates, then that person would be entitled
to sell those shares without complying with any of the requirements of Rule 144.
In
general, under Rule 144, as currently in effect, our affiliates or persons selling shares on behalf of our affiliates are entitled to sell upon expiration of the
lock-up and market standoff agreements described above, within any three-month period, a number of shares that does not exceed the greater of:
•
1% of the number of shares of our common stock then outstanding, which will equal
approximately                        shares
immediately after this offering; or
•
the average weekly trading volume of our common stock during the four calendar weeks preceding the filing of a notice on
Form 144 with respect to that sale.
Sales
under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to
the availability of current public information about us.
Rule 701
Rule 701 generally allows a stockholder who purchased shares of our common stock pursuant to a written compensatory plan or
contract and who is not deemed to have been an affiliate of our company during the immediately preceding 90 days to sell these shares in reliance upon Rule 144, but without being
required to comply with the public information, holding period, volume limitation or notice provisions of Rule 144. Rule 701 also permits affiliates of our company to sell their
Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. All holders of Rule 701 shares, however, are required by that rule to
wait until 90 days after the date of this prospectus before selling those shares pursuant to Rule 701.
131
Table of Contents
Stock Options
As soon as practicable after the closing of this offering, we intend to file one or more registration statements on
Form S-8 under the Securities Act covering all of the shares of our common stock subject to outstanding options and the shares of our common stock reserved for issuance under our
stock plans. In addition, we intend to file a registration statement on Form S-8 or such other form as may be required under the Securities Act for the resale of shares of
our common stock issued upon the exercise of options that were not granted under Rule 701. We expect to file this registration statement as soon as permitted under the Securities Act. However,
the shares registered on Form S-8 may be subject to the volume limitations and the manner of sale, notice and public information requirements of Rule 144 and will not be
eligible for resale until expiration of the lock-up and market standoff agreements to which they are subject.
Registration Rights
We have granted demand, piggyback and Form S-3 registration rights to certain of our stockholders to sell our common
stock. Registration of the sale of these shares under the Securities Act would result in these shares becoming freely tradable without restriction under the Securities Act immediately upon the
effectiveness of the registration, except for shares purchased by affiliates. For a further description of these rights, see "Description of Capital Stock—Registration Rights."

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES TO NON-U.S. HOLDERS
The following is a summary of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of our
common stock to non-U.S. holders (defined below), who purchase our common stock pursuant to this offering and hold our stock as a capital asset (generally, on asset hold for investment
purposes), but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively,
so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service (the "IRS") with respect to the statements
made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.
This
summary does not address the tax considerations arising under the laws of any foreign, state or local jurisdiction. Except to the limited extent below, this summary does not address
tax considerations arising under estate or gift tax laws. In addition, this discussion does not address tax considerations applicable to an investor's particular circumstances or to investors that may
be subject to special tax rules, including, without limitation:
•
banks, insurance companies or other financial institutions;
•
persons subject to the alternative minimum tax;
•
tax-exempt organizations or tax-qualified retirement plans;
•
real estate investment trusts or regulated investment companies;
•
controlled foreign corporations or passive foreign investment companies;
•
persons who acquired our common stock as compensation for services;
•
dealers in securities or currencies;
•
traders in securities that elect to use a mark-to-market method of accounting for their securities
holdings;
•
persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth
below);
•
certain former citizens or long-term residents of the United States;
•
persons who hold our common stock as a position in a hedging transaction, "straddle," "conversion transaction" or other
risk reduction transaction; or
•
persons deemed to sell our common stock under the constructive sale provisions of the Code.
In
addition, if a partnership (including any other entity classified as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner
generally will depend on
the status of the partner and upon the activities of the partnership. Accordingly, this summary does not address tax considerations applicable to partnerships that hold our common stock, and partners
in such partnerships should consult their tax advisors.

Table of Contents
YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION, AS WELL AS
ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE UNITED STATES FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR
OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.
Non-U.S. Holder Defined
For purposes of this discussion, you are a non-U.S. holder if you are any holder, other than:
•
an individual citizen or resident of the United States;
•
a corporation or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in the
United States or under the laws of the United States or any political subdivision thereof;
•
an estate whose income is subject to U.S. federal income tax regardless of its source; or
•
a trust (x) whose administration is subject to the primary supervision of a U.S. court and which has one or more
U.S. persons who have the authority to control all substantial decisions of the trust or (y) which has made an election to be treated as a U.S. person for U.S. federal income tax purposes.
If
you are an individual, you may, in many cases, be deemed to be a resident alien, as opposed to a nonresident alien, by virtue of being present in the United States for at least
31 days in the calendar year and for an aggregate of at least 183 days during a three-year period ending in the current calendar year. For these purposes, all the days
present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year are counted.
Resident aliens are subject to U.S. federal income tax as if they were U.S. citizens. Such an individual is urged to consult his or her own tax advisor regarding U.S. federal income tax consequences
of the ownership of our common stock.
Distributions
We have not made any distributions on our common stock, and we do not plan to make any distributions for the foreseeable future.
However, if we do make distributions on our common stock, those payments will constitute dividends for U.S. tax purposes to the extent paid from our current or accumulated earnings and profits, as
determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and
will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock.
Any
dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an
applicable income tax treaty. Generally, in order for us or our paying agent to withhold tax at a lower treaty rate, a non-U.S. holder must certify its entitlement to treaty benefits. A
non-U.S. holder generally can meet this certification requirement by providing a Form W-8BEN (or any successor form) or appropriate substitute form to us or our paying
agent. If the holder holds the stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to the agent. The
holder's agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. For payments made to a foreign partnership or other
pass-through entity, the certification requirements generally apply to the partners
134
Table of Contents
or
other owners rather than to the partnership or other entity, and the partnership or other entity must provide the partners' or other owners' documentation to us or our paying agent.
Dividends
received by you that are effectively connected with your conduct of a U.S. trade or business and, if required by an applicable income tax treaty, attributed to a permanent
establishment in the United States, are exempt from such withholding tax. In order to obtain this exemption, you must provide us with an applicable IRS form W-8 (generally
Form W-8ECI) properly certifying such exemption. Such effectively connected dividends, although not subject to withholding tax, are taxed at the same graduated rates applicable to
U.S. persons, net of certain deductions and credits and subject to an applicable income tax treaty providing otherwise. In addition, if you are a corporate non-U.S. holder, dividends that
you receive that are effectively connected with your conduct of a U.S. trade or business, subject to certain adjustments, may also be subject to a branch profits tax at a rate of 30% or such lower
rate as may be specified by an applicable income tax treaty.
If
you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may be able to obtain a refund of any excess amounts currently withheld if you timely file an
appropriate claim for refund with the IRS.
Gain on Disposition of Common Stock
You generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common
stock unless:
•
the gain is effectively connected with your conduct of a U.S. trade or business (and, if an income tax treaty applies, the
gain is attributable to a permanent establishment maintained by you in the United States);
•
you are an individual who is present in the United States for a period or periods aggregating 183 days or more
during the calendar year in which the sale or disposition occurs and certain other conditions are met; or
•
our common stock constitutes a U.S. real property interest by reason of our status as a "United States real property
holding corporation" for U.S. federal income tax purposes (a "USRPHC"), at any time within the shorter of the five-year period preceding the disposition or your holding period for our
common stock.
We
believe that we are not currently and will not become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real
property relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our
common stock is regularly traded on an established securities market, such common stock will be treated as a U.S. real property interest only if you actually or constructively hold more than 5% of
such regularly traded common stock at any time during the applicable period that is specified in the Code.
If
you are a non-U.S. holder described in the first bullet above, you will generally be required to pay tax on the net gain derived from the sale under regular graduated U.S.
federal income tax rates, and corporate non-U.S. holders described in the first bullet above may be subject to the additional branch profits tax at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be required to pay a flat 30% tax on the gain derived
from the sale, which tax may be offset by U.S. source capital losses (even though you are not considered a resident of the United States). You should consult any applicable income tax or other
treaties that may provide for different rules.
135
Table of Contents
Federal Estate Tax
Our common stock that is held by an individual non-U.S. holder at the time of death will be included in such holder's gross
estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.
Backup Withholding and Information Reporting
Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax
withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of
residence.
Payments
of dividends or of proceeds on the disposition of stock made to you may be subject to additional information reporting and backup withholding (currently at a rate of 28%) unless
you either (i) provide a correct taxpayer identification number and certify that you are not subject to backup withholding on Form W-9, or (ii) establish an exemption,
for example by properly certifying your non-U.S. status on a Form W-8BEN or another appropriate version of IRS Form W-8. Notwithstanding the
foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person and you have not provided a
correct taxpayer identification number, or if we or our paying agent has received notice from the IRS that backup withholding is required.
Backup
withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund or credit generally may be obtained, provided that the required information is furnished to the IRS in a timely manner.
Recent Legislative Developments
Recent legislation may begin imposing withholding at a rate of 30% on payments to certain foreign entities (including financial
institutions, as specifically defined in this new legislation and certain other non-U.S. entities) of dividends on, and the gross proceeds of dispositions of, U.S. common stock, unless
(i) the foreign financial institution undertakes certain diligence and reporting obligations or (ii) the foreign non-financial entity either certifies it does not have any
substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner. If the payee is a foreign financial institution, it must enter into an agreement with the U.S.
Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and
withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. The withholding requirements are generally scheduled to
phase-in beginning on January 1, 2014. You should consult your tax advisor regarding the possible implications of this legislation on your investment in our common stock.

The
underwriting agreement provides that the underwriters are obligated to purchase all the shares of common stock in this offering if any are purchased, other than those shares covered
by the over-allotment option described below. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters
may be increased or the offering may be terminated.
We
and the selling stockholders have granted to the underwriters a 30-day option to purchase up to                        additional
shares from us at the initial public offering
price less the underwriting discounts and commissions. The option may be exercised only to cover any over-allotments of common stock.
The
underwriters proposes to offer the shares of common stock initially at the public offering price on the cover page of this prospectus and to selling group members at that price less
a selling concession of $            per share. After the initial public offering the representatives may change the public offering price and concession and discount to broker/dealers.

The
representatives have informed us that they do not expect sales to accounts over which the underwriters have discretionary authority to exceed 5% of the shares of common stock being
offered.
We
have agreed that we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Securities and Exchange Commission a registration
statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose
the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of the representatives for a period of 180 days after the date of this prospectus.
However, in the event that either (1) during the last 17 days of the "lock-up" period, we release earnings results or material news
137
Table of Contents
or
a material event relating to us occurs or (2) prior to the expiration of the "lock-up" period, we announce that we will release earnings results during the 16-day
period beginning on the last day of the "lock-up" period, then in either case the expiration of the "lock-up" will be extended until the expiration of the 18-day
period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless the representatives waive, in writing, such an extension.
Our
officers and directors and holders of substantially all of our outstanding stock and options have agreed that they will not offer, sell, contract to sell, pledge or otherwise dispose
of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, enter into a transaction that would have
the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock, whether any of these
transactions are to be settled by delivery of our common stock or other securities, in cash or otherwise, or publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter
into any transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of the representatives for a period of 180 days after the date of this prospectus.
However, in the event that either (1) during the last 17 days of the 'lock-up" period, we release earnings results or material news or a material event relating to us occurs
or (2) prior to the expiration of the "lock-up" period, we announce that we will release earnings results during the 16-day period beginning on the last day of the
"lock-up" period, then in either case the expiration of the "lock-up" will be extended until the expiration of the 18-day period beginning on the date of the
release of the earnings results or the occurrence of the material news or event, as applicable, unless the representatives waive, in writing, such an extension.
The
restrictions described in the two immediately preceding paragraphs shall not apply to:
•
transactions by a director, officer or stockholder relating to shares of common stock or other securities acquired in open
market transactions after the completion of the offering of the shares;
•
the sale of shares of common stock pursuant to the underwriting agreement;
•
the issuance by us of shares of common stock upon the exercise of an option or warrant or the conversion of a security
outstanding on the date of and as described in this prospectus;
•
transfers of shares of common stock or any securities convertible into or exercisable or exchangeable for common stock by
a director, officer or stockholder (i) as a bona fide gift, or gifts, (ii) to a family member or trust, or (iii) to affiliates of the director, officer or stockholder, and if such
stockholder is an entity, including limited partners, members or stockholders, provided that it shall be a condition of the transfer that each transferee agrees to be bound in writing by the terms of
the "lock-up" prior to such transfer, such transfer shall not involve a disposition for value and no filing under Section 13 or 16 of the Exchange Act shall be required or shall be made
voluntarily during the 180-day restricted period;
•
the exercise of options granted under our 2002 Stock Option/Stock Issuance Plan or 2012 Equity Incentive Plan or warrants
outstanding on the date of this prospectus, in each case by a director, officer or stockholder, provided that no filing under Section 16(a) of the Exchange Act reporting the disposition of
shares of common stock or any other reduction in the beneficial ownership of shares is required or voluntarily made in connection with these transactions during this 180-day restricted
period;
•
the issuance or grant by us of shares, or options to purchase shares of, common stock pursuant to our stock plans
described in this prospectus, provided that the recipient of such services or options shall sign and deliver a copy of the lock-up agreement to the extent such shares or options become
vested within 180 days after the date of this prospectus;
138
Table of Contents
•
the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of
shares of common stock, provided that such plan does not provide for the transfer of common stock during the 180-day restricted period and that no public filing or other public
announcement of such plan by us or such holders regarding the establishment of such plan is not required to be or voluntarily made during this 180-day restricted period; and
•
the filing by us of a registration statement on Form S-8 in respect of any shares issued under or the
grant of any award pursuant to an employee benefit plan described in this prospectus.
We
and the selling stockholders have agreed to indemnify the underwriters against liabilities under the Securities Act, or contribute to payments that the underwriters may be required to
make in that respect.
We
have applied to list the shares of common stock on the NASDAQ Global Market, under the symbol "PFPT."
In
connection with the offering the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in
accordance with Regulation M under the Exchange Act.
•
Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum.
•
Over-allotment involves sales by the underwriters of shares in excess of the number of shares the underwriters
are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of
shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of
shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any covered short position by either exercising their
over-allotment option and/or purchasing shares in the open market.
•
Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been
completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares
available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be
covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created
if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.
•
Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common stock
originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.
These
stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or
retarding a decline in the market price of the common stock. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions
may be effected on the NASDAQ Global Market or otherwise and, if commenced, may be discontinued at any time.
A
prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters, or selling group members, if any, participating in this offering
and one or more of the underwriters participating in this offering may distribute prospectuses electronically. The
139
Table of Contents
representatives
may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the
underwriters and selling group members that will make Internet distributions on the same basis as other allocations.
From
time to time, the underwriters may perform investment banking and advisory services for us for which they may receive customary fees and expenses.
In
the ordinary course of business, we have, and may in the future, sell solutions or services to one or more of the underwriters in arms length transactions on market competitive terms.
The
shares of common stock are offered for sale in those jurisdictions in the United States, Europe and elsewhere where it is lawful to make such offers.
Each
of the underwriters has represented and agreed that it has not offered, sold or delivered and will not offer, sell or deliver any of the shares of common stock directly or
indirectly, or distribute this prospectus or any other offering material relating to the shares of common stock, in or from any jurisdiction except under circumstances that will result in compliance
with the applicable laws and regulations thereof and that will not impose any obligations on us except as set forth in the underwriting agreement.

In relation to each Member State of the European Economic Area that has implemented the Prospectus Directive, each, a Relevant Member
State, each underwriter represents and agrees that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State, or the Relevant
Implementation Date, it has not made and will not make an offer of Securities to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Securities that

Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Securities to the public in that

(c)   to

for any such offer; or
(d)   in
any other circumstances that do not require the publication by the Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.
For
the purposes of this provision, the expression an "offer of Shares to the public" in relation to any Shares in any Relevant Member State means the communication in any form and by
any means of sufficient information on the terms of the offer and the Shares to be offered so as to enable an investor to decide to purchase or subscribe the Shares, as the same may be varied in that
Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing
measure in each Relevant Member State.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To
the Board of Directors and Stockholders of Proofpoint, Inc.
In
our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, convertible preferred stock and stockholders' deficit and cash flows
present fairly, in all material respects, the financial position of Proofpoint, Inc. and its subsidiaries (the "Company") at December 31, 2010 and 2009, and the results of their
operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of
these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

1. The Company and Summary of Significant Accounting Policies
The Company
Proofpoint, Inc. (the "Company") was incorporated in Delaware in June 2002 and is headquartered in California.
Proofpoint
is a pioneering security-as-a-service vendor that enables large and mid-sized organizations worldwide to defend, protect,
archive and govern their most sensitive data. The Company's security-as-a-service platform is comprised of a number of data protection solutions, including threat
protection, regulatory compliance, archiving and governance, and secure communication.
Liquidity
The Company has relied principally on preferred stock financings to fund its operating activities to date and at September 30,
2011, the Company had an accumulated deficit of $155,694. During the years ended December 31, 2008, 2009 and 2010, and the nine months ended September 30, 2011 the Company incurred a net
loss of $25,888, $19,738, $20,865 and $13,717 (unaudited), respectively, and had negative cash flows from operations of $7,555 and $3,707, positive
cash flows from operations of $3,409 and negative cash flows from operations of $329 (unaudited), respectively. Management plans to improve operating results by growing revenue while controlling
costs. Management believes that its plans provide sufficient liquidity for the Company to finance its operations for at least the next 12 months from December 31, 2010. There is no
assurance, however, that management will be successful with its plans or otherwise achieve its intended business objectives and that financing alternatives, if needed, will be available on terms
acceptable to the Company, or at all. Failure to generate sufficient cash from operations, raise additional capital or control operating costs may require the Company to modify, delay or abandon
planned expenditures and could have an impact on the Company's ability to achieve intended business objectives.
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All
intercompany transactions and balances have been eliminated in consolidation.
Foreign Currency Remeasurement and Transactions
The Company's sales to international customers are generally U.S. dollar-denominated. As a result, there are no significant foreign
currency gains or losses related to these transactions. The functional currency for the Company's wholly-owned foreign subsidiaries is the U.S. dollar. Accordingly, the subsidiaries
remeasure monetary assets and liabilities at period-end exchange rates, while nonmonetary items are remeasured at historical rates. Income and expense accounts are remeasured at the
average exchange rates in effect during the year. Remeasurement adjustments are recognized in the consolidated statement of operations as transaction gains or losses within other income (expense),
net, in the period of occurrence. Aggregate transaction losses included in determining net loss was $166, $177 and $187 for the years ended December 31, 2008, 2009 and 2010, respectively and a
net loss of $58 (unaudited) and a net gain of $93 (unaudited) for the nine months ended September 30, 2010 and 2011, respectively.

1. The Company and Summary of Significant Accounting Policies (Continued)
Certain Significant Risks and Uncertainties
The Company operates in a rapidly changing environment that involves a number of risks, some of which are beyond the Company's control
that could have a material adverse effect on the Company's business, operating results, and financial condition. These risks include, among others, the Company's: history of losses, and ability to
achieve profitability in the future; highly competitive environment with large established competitors; ability to maintain high subscription renewal rates and sell additional solutions to current
subscribers; ability to maintain demand for its solutions if there is significant migration of on-premise corporate email systems to the cloud or if new messaging and collaboration
technologies cause a decline in the use of email; ability to protect its customers from security breaches; and potential data losses.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates and such difference may be material to the financial statements.
Cash and Cash Equivalents
The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of
purchase to be cash equivalents. Cash equivalents consist of money market funds. Cash equivalents were $4,270 and $8,660 as of December 2009 and 2010, respectively, and $2,776 of September 30,
2011 (unaudited).
Short-term Investments
Short-term investments consist of readily marketable securities with remaining maturity of more than three months from the
date of purchase and include
commercial paper, corporate bonds, and debt securities. At December 31, 2009, 2010 and September 30, 2011 (unaudited), all of the Company's short-term investments were
classified as available-for-sale and were carried at fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive loss. Realized
gains and losses are included in "other income (expense), net." Fair value is estimated based on available market information. The cost of securities sold is based on the specific identification
method.
Inventories
Inventories are stated at lower of cost or market value, with costs computed on a first-in, first-out basis.
Cost is determined using standard costs which approximate actual costs. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net
realizable values when they are determined to be less than cost.
Inventories
held at December 31, 2009, 2010 and the nine months ended September 30, 2011 (unaudited) consists of finished goods.

1. The Company and Summary of Significant Accounting Policies (Continued)
Revenue Recognition
The Company derives its revenue primarily from two sources: (1) subscription revenue for rights related to the use of the
security-as-a-service platform and (2) hardware, training and professional services revenue provided to customers related to their use of the platform.
Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to three years, and consist of (i) subscription fees from the
licensing of the security-as-a-service platform, (ii) subscription fees for access to the on-demand elements of the platform and
(iii) subscription fees for the right to access the company's customer support services.
The
Company applies the provision of ASC 985-605, "Software Revenue Recognition," and related interpretations, to all transactions involving the licensing of software, as
well as related support, training, and other professional services. ASC 985-605 requires revenue earned on software arrangements involving multiple elements such as software license,
support, training and other professional services to be allocated to each element based on the relative fair values of these elements. The fair value of an element must be based on vendor-specific
objective evidence ("VSOE") of fair value. VSOE of fair value of each element is based on the price charged when the element is sold separately. Revenue is recognized when all of the following
criteria are met as set forth in ASC 985-605:
•
Persuasive evidence of an arrangement exists,
•
Delivery has occurred,
•
The fee is fixed or determinable, and
•
Collectability is probable.
The
Company has analyzed all of the elements included in its multiple element arrangements and has determined that it does not have sufficient VSOE of fair value to allocate revenue to
its subscription and software license agreements, support, training, and professional services. The Company defers all revenue under the software arrangement until the commencement of the subscription
services and any associated professional services. Once the subscription services and the associated professional services have commenced, the entire fee from the arrangement is recognized ratably
over the remaining period of the arrangement. If the professional services are essential to the functionality of the subscription, then the revenue recognition does not commence until such services
are completed.
The
hosted on-demand service agreements do not provide customers with the right to take possession of the software supporting the hosted service. The Company recognizes
revenue from its hosted on-demand services in accordance with ASC 605-20, and as such recognizes revenue when the following criteria are met:
•
Persuasive evidence of an arrangement exists,
•
Delivery of the Company's obligations to its customers has occurred,
•
Collection of the fees is probable, and
•
The amount of fees to be paid by the customer is fixed or determinable.

1. The Company and Summary of Significant Accounting Policies (Continued)
In
October 2009, the FASB amended the accounting guidance for multiple element arrangements ("ASU 2009-13") to:
•
Provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be
separated, and how the arrangement consideration should be allocated among its elements;
•
Require an entity to allocate revenue in an arrangement that has separate units of accounting using best estimated selling
price ("BESP") of deliverables if a vendor does not have VSOE of fair value or third-party evidence of selling price ("TPE"), and
•
Eliminate the use of the residual method and require an entity to allocate revenue using the relating selling price method
to the separate unit of accounting.
Concurrently,
the FASB amended the accounting guidance for revenue recognition ("ASU 2009-14") to exclude hardware appliances containing software components and hardware
components that function together to deliver the hardware appliance's essential functionality from the scope of the software revenue recognition guidance of ASC 985-605.
The
Company elected to adopt this new guidance in the first quarter of fiscal 2011 for new and materially modified revenue arrangements originating after January 1, 2011.
Prior
to the adoption of ASU 2009-14, revenue derived from hardware appliance sales were recognized based on the software revenue recognition guidance. The Company could not
establish VSOE of fair value for the undelivered elements in the arrangement, and therefore the entire fee from the arrangement was recognized ratably over the contractual term of the agreement. In
addition, the Company was unable to establish VSOE of fair value of its hosted on-demand service agreements, and therefore the entire fee for the agreement was recognized ratably over the
contractual term of the agreement.
As
a result of the adoption of this accounting guidance, revenue derived from our subscription services and hardware appliance sales are no longer subject to industry-specific software
revenue recognition guidance. For all arrangements within the scope of these new accounting pronouncements, including the Company's hosted on-demand services, the Company evaluates each
element in a multiple element arrangement to determine whether it represents a separate unit of accounting. An element constitutes a separate unit of accounting when the delivered item has standalone
value and delivery of the undelivered element is probable and within the Company's control. Revenue derived from the licensing of the security-as-a-service platform
continue to be accounted for in accordance with the industry specific revenue recognition guidance.
Hardware
appliance revenue is recognized upon shipment. Subscription and support revenue are recognized over the contract period commencing on the start date of the contract.
Professional services and training, when sold with hardware appliances or subscription and support services, are accounted for separately when those services have standalone value. In determining
whether professional services and training services can be accounted for separately from subscription and support services, the Company considers the following factors: availability of the services
from other vendors, the nature of the services, and the dependence of the subscription services on the customer's decision to buy the professional services. If professional services and training do
not qualify for separate accounting, the

Company
recognizes the professional services and training ratably over the contract term of the subscription services.
Delivery
generally occurs when the hardware appliance is delivered to a common carrier freight on board shipping point by the Company or the hosted service has been activated and
communicated to the customer accordingly. The Company's fees are typically considered to be fixed or determinable at the inception of an arrangement and are negotiated at the outset of an arrangement,
generally based on specific products and quantities to be delivered. In the event payment terms are provided that differ significantly from its standard business practices, the fees are deemed to not
be fixed or determinable and revenue is recognized as the fees become paid.
The
Company assesses collectability based on a number of factors, including credit worthiness of the customer and past transaction history of the customer. Through September 30,
2011, the Company has not experienced significant credit losses.
Revenue
as reported and pro forma revenue that would have been reported during the nine months ended September 30, 2011, had the Company not adopted the new guidance is shown in

$

Deferred Revenue
Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the sale of the Company's
subscription fees, and training and professional services. Once the revenue recognition criteria are met, this revenue is recognized ratably over the term of the associated contract, which typically
range from 12 to 36 months.
Deferred Product Costs
Deferred product costs are the incremental costs that are directly associated with each noncancelable customer contract or hosting
agreement and primarily consist of cost of appliances and royalty payments made to third parties, from whom the Company has obtained licenses to integrate certain software into its products. The costs
are deferred and amortized over the noncancelable term of the related customer contract or hosting agreement, which typically range from 12 to 36 months.
Software Development Costs
We capitalize certain software development costs, including the costs to develop new software solutions or significant enhancements to
existing solutions, which are developed or obtained for internal use. We capitalize software development costs when application development begins, it is probable that the project will be completed,
and the software will be used as intended. Such capitalized costs are amortized on a straight-line basis over the estimated useful life of the related asset, which is generally two years.
Costs associated with preliminary project stage activities, training, maintenance and all post implementation stage activities are expensed as incurred.

1. The Company and Summary of Significant Accounting Policies (Continued)
Software
development costs related to software services to be sold are capitalized when technological feasibility has been established. Amortization of capitalized software development
costs will begin as each product is available for general release to customers. Amortization will be computed on an individual solution basis for those solutions available for market and will be
recognized based on the solution's economic life. Because the Company believes its current process for developing software is essentially completed concurrently with the establishment of technology
feasibility. Costs associated with the development work between technological feasibility and the general availability has not been material and as such we have not capitalized any development costs
to date.
Property and Equipment
Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated
useful life of the related asset, which is generally one to three years. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the lease
term or the estimated useful life of the asset or improvement. Cost of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. When property
and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is included in the other income
(expense), net, in the consolidated statement of operations during the period.
Impairment of Long-Lived Assets
In accordance with ASC 360, "Property, Plant, and Equipment," the Company evaluates long-lived assets, such as property and
equipment, including intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.
Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be
impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. No assets were determined to be impaired to date.
Advertising and Promotion Costs
Expenses related to advertising and promotion of solutions is charged to sales and marketing expense as incurred. The Company did not
incur any significant advertising and promotion expenses during the years ended December 31, 2008, 2009 and 2010, and for the nine months ended September 30, 2010 (unaudited) and 2011
(unaudited), respectively.
Goodwill and Intangible Assets
Goodwill represents the excess of the purchase price of the acquired enterprise over the fair value of identifiable assets acquired and
liabilities assumed. The Company applies ASC 350, "Intangibles—Goodwill and Other," and performs an annual goodwill impairment test. For the purposes of impairment testing, the Company has
determined that it has one reporting unit. A two-step impairment test of goodwill is required pursuant to ASC 350-20-35. In the first step, the fair value of the
reporting unit is compared to its carrying value. If the fair value exceeds the carrying value, goodwill is not impaired and further testing is not required. If the carrying value exceeds the fair
value, then the second step of the impairment test is required to determine the implied fair value of the reporting
F-12
Table of Contents
Proofpoint, Inc.
Notes to Consolidated Financial Statements (Continued)
(in thousands, except per share amounts)
1. The Company and Summary of Significant Accounting Policies (Continued)
unit's
goodwill. The implied fair value of goodwill is calculated by deducting the fair value of all tangible and intangible net assets of the reporting unit, excluding goodwill, from the fair value
of the reporting unit as determined in the first step. If the carrying value of the reporting unit's goodwill exceeds its implied fair value, then an impairment loss must be recorded that is equal to
the difference. The identification and measurement of goodwill impairment involves the estimation of the fair value of the Company. The estimate of fair value of the Company, based on the best
information available as of the date of the assessment, is subjective and requires judgment, including management assumptions about expected future revenue forecasts and discount rates. No impairment
to the carrying value of goodwill was identified by the Company during the years ended December 31, 2009 and 2010 or the nine months ended September 30, 2011 (unaudited).
Intangible
assets consist of developed technology, vendor relationships and customer relationships. The values assigned to intangibles are based on estimates and judgments regarding
expectations for success and life cycle of solutions and technologies acquired.
Intangible
assets are amortized on a straight-line basis over their estimated lives, which approximate the pattern in which the economic benefits of the intangible assets are
consumed, as follows:
Developed technology
4 years
Customer relationships
4 years
Vendor relationships
4 years
Fair Value of Financial Instruments
The carrying amounts of certain of the Company's cash equivalents, accounts receivable, accounts payable and accrued liabilities
approximate their fair values due to their short maturities. Based on borrowing rates that are available to the Company for loans with similar terms and consideration of the Company's credit risk, the
carrying value of the note payable approximates its fair value. The carrying value of the preferred stock warrant liability represents its fair value. See Note 6, "Financial Instruments and
Fair Value Measurements," regarding the fair values of the Company's investments and preferred stock warrant liability.
Warranty
The Company provides limited warranties on all sales and provides for the estimated cost of the warranties at the date of sale, to the
extent not already provided by its own vendors. The estimated cost of warranties has not been material to date.
Income Taxes
The Company accounts for income taxes under ASC 740, "Income Taxes." Under ASC 740, deferred tax assets and liabilities are determined
based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected
to reverse. A valuation allowance is established to reduce net deferred tax assets to an amount that the Company estimates is more likely than not to be realized.

1. The Company and Summary of Significant Accounting Policies (Continued)
The
Company has elected to use the "with and without" approach as described in ASC 740-20, "Intraperiod Tax Allocation," in determining the order in which tax attributes are
utilized. As a result, the Company will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax
attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the impact of stock-based awards on other tax attributes, such as the research tax
credit, through the consolidated statement of operations.
Effective
January 1, 2009, the Company adopted the accounting guidance for uncertainties in income taxes, which prescribes a recognition threshold and measurement process for
recording uncertain tax positions taken, or expected to be taken in a tax return, in the financial statements. Additionally, the guidance also prescribes new treatment for the derecognition,
classification, accounting in interim periods and disclosure requirements for uncertain tax positions. The Company accrues for the estimated amount of taxes for uncertain tax positions if it is more
likely than not that the Company would be required to pay such additional taxes. An uncertain tax position will not be recognized if it has a less than 50% likelihood of being sustained.
The
Company recognizes interest and penalties related to tax positions in income tax expense. To the extent that accrued interest and penalties do not ultimately become payable, amounts
accrued will be reduced and reflected as a reduction of the overall income tax provision in the period that such determination is made. No interest or penalties have been accrued for any period
presented.
Employee Benefit Plans
The Company sponsors a 401(k) defined contribution plan covering all employees. The Company may make discretionary contributions to the
401(k). To date, no contributions have been made by the Company.
Stock-Based Compensation
The Company accounts for stock-based compensation under ASC 718, "Compensation—Stock Compensation" using the
prospective transition method prescribed for private companies. Using the prospective transition method, compensation expense recognized includes the compensation cost for all share-based payment
awards granted to employees subsequent to December 31, 2005, based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company uses the
Black-Scholes option pricing model to determine the fair value of stock options. Stock compensation expense is recognized on a straight-line basis over the requisite service period of the
award, which generally equals the vesting period.
Under
ASC 718, the Company is required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures is computed based
on historical data of employee turnover and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in
estimated forfeitures are recognized in the period of change and will impact the amount of stock compensation expenses to be recognized in future periods.

Stock-based
compensation expense recognized is shown in the operating activities section of the consolidated statements of cash flows. In addition, ASC 718 requires the cash flows
resulting from the tax benefits due to tax deductions on stock option exercises in excess of the stock-based compensation expense recognized (excess tax benefits) to be classified in the financing
activities section of the consolidated statements of cash flows. During the years ended December 31, 2008, 2009, 2010, and the nine months ended September 30, 2010 (unaudited) and 2011
(unaudited), the Company did not recognize any excess tax benefits.
The
Company accounts for stock options issued to nonemployees in accordance with the provisions of ASC 505-50 using a fair-value approach. The measurement of
stock-based compensation for nonemployees is subject to periodic adjustments as the options vest, and the expense is recognized over the period over which services are received.
Comprehensive Income (Loss)
Comprehensive income (loss) includes all changes in equity that are not the result of transactions with stockholders. The Company's
comprehensive income (loss) consists of its net loss and changes in unrealized gains (losses) from its available-for-sale investments.
Unaudited Interim Financial Information
The consolidated financial statements as of September 30, 2011, and for the nine months ended September 30, 2011 and
September 30, 2010 are unaudited. All disclosures as of September 30, 2011 and for the nine months ended September 30, 2011 and September 30, 2010, presented in the notes
to the financial statements are unaudited. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect
all normal recurring adjustments necessary for a fair statement of the Company's financial position as of September 30,2011 and the results of operations and cash flows for the nine months
ended September 30, 2011. The results of operations for the nine months ended
September 30, 2011 are not necessarily indicative of the results to be expected for the year ended December 31, 2011 or for other interim periods or for future years.
Unaudited Pro Forma Stockholders' Deficit
The September 30, 2011 unaudited pro forma stockholders' deficit has been prepared assuming that upon the closing of a
qualifying initial public offering all of the Company's convertible preferred stock outstanding will automatically convert into shares of common stock. The September 30, 2011 unaudited pro
forma stockholders' deficit reflects the conversion of all outstanding preferred stock into shares of common stock.
Recent Accounting Pronouncements
In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amended guidance eliminates one of the
presentation options provided by current U.S. GAAP that is to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, it
gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a

single
continuous statement of comprehensive income or in two separate but consecutive statements. This guidance will be effective for reporting periods beginning after December 15, 2011 and
will be applied retrospectively. We do not expect that this guidance will have an impact on our financial position, results of operations or cash flows.
In
September 2011, the Financial Accounting Standards Board (the "FASB") issued amended guidance relating to the goodwill impairment test. The guidance allows an entity an option to
first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under that option, an entity no longer would be
required to calculate the fair value of a reporting unit unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its
carrying amount. The guidance also includes examples of the types of events and circumstances to consider in conducting the qualitative assessment. The guidance will be effective for annual and
interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. We are currently evaluating the impact of this amended guidance on
our consolidated financial statements.
2. Acquisitions
Fortiva, Inc.
On June 20, 2008, the Company entered into a Share Purchase Agreement (the "Fortiva Agreement") with Fortiva, Inc.
("Fortiva"), an Ontario, Canada corporation, by which the Company acquired 100% of the outstanding shares of Fortiva.
Under
the terms of the Fortiva Agreement, the acquisition was closed in exchange for cash payment of $5,460, cash settlement of Fortiva's outstanding debt for $1,267, issuance to the
former shareholders of Fortiva of 3,100 shares of Series F preferred stock at its fair value of $16,492 ($5.32 per share). The purchase consideration also included the acquisition related costs
of $1,031. The results of Fortiva's operations have been included in the consolidated financial statements since the acquisition date.
The
Company acquired Fortiva to provide the Company with a number of benefits, including acquiring technology and adding meaningful scale to its existing business in the United States
and providing exposure into the Canadian market. The total purchase price recorded was as follows:

The
acquisition was accounted for as a purchase business combination. The Company allocated the purchase price to tangible assets acquired, liabilities assumed and identifiable
intangible assets acquired based on their estimated fair values. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The goodwill is not deductible for tax
purposes. The following table

Secure Data in Motion, Inc.
On August 4, 2008, the Company entered into an Asset Purchase Agreement (the "Sigaba Agreement") with Secure Data in
Motion, Inc. ("Sigaba"), a Delaware corporation, that was accounted for as a business combination.
Under
the terms of the Sigaba Agreement, the Company paid total consideration of $461 for the assets. In addition, the Company agreed to pay an additional 20% of the "renewal fees," as
specified in
the Sigaba Agreement, actually collected by the Company from each existing Sigaba customer upon renewal up to a maximum of $150. The minimum amount due to Sigaba under the term of above agreement was
$75 as of December 31, 2008, which was recorded to operating expenses in fiscal year 2008.
The
total cash consideration of $461 was allocated to goodwill.
Everyone.net, Inc.
On October 21, 2009, the Company entered into an Agreement of Merger (the "EDN Agreement") with Everyone.net, Inc.
("EDN"), a California corporation, by which the Company acquired 100% of the outstanding shares of EDN. Under the terms of the EDN Agreement, the acquisition was closed in exchange for cash payment of
$5,496, cash settlement of EDN's outstanding debts totaling $1,330, issuance of 188 shares of Series F preferred stock at its fair value of $1,000 ($5.32 per share). Additionally, the Company
agreed to pay additional earn-out consideration ("earn-out") of up to $2,000 through November 2011, such earn-out being contingent upon the achievement of specified
financial targets. The initial fair value of the earn-out of $1,495 was recorded as part of the purchase consideration. The change in fair value of the earn-out of $208 during
the nine months ended September 30, 2011, was recognized as a charge to interest income (expense), net for the year. The acquisition related costs of $559 incurred by the Company was charged to
operating expense in the year ended December 31, 2009. The results of EDN's operations have been included in the consolidated financial statements since the acquisition date. During the year
ended December 31, 2010, the Company paid $1,000 of earn-out to the sellers. The remaining payout of $1,000 will be paid in December 2011 and is fully accrued for at
September 30, 2011 given that the performance criteria had been met at September 30, 2011. The Company also received $180 during the year ended December 31, 2010, in a working
capital adjustment following the closing of the acquisition and such amount was recorded in the

3. Concentration of Risks
Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable.
The
Company limits its concentration of risk in cash equivalents and short-term investments by diversifying its investments among a variety of industries and issuers and by
limiting the average maturity to one year or less. The Company's professional portfolio managers adhere to this investment policy as approved by the Company's board of directors.
The
Company's investment policy is to invest only in fixed income investments denominated and payable in U.S. dollars. Investment in obligations of the U.S. government and its agencies,
money market instruments, commercial paper, certificates of deposit, bankers' acceptances, corporate bonds of U.S. companies, municipal securities and asset backed securities are allowed. The Company
does not invest in auction rate securities, futures contracts, or hedging instruments.

3. Concentration of Risks (Continued)
The
Company's accounts receivables are derived from revenue earned from customers primarily located in the United States of America. The Company performs periodic evaluations of its
customers' financial condition and generally does not require its customers to provide collateral or other security to support accounts receivable, and maintains an allowance for doubtful accounts.
Credit losses historically have not been significant.
No
single customer accounted for more than 10% of total revenue in the years ended December 31, 2008, 2009, 2010 and for the nine months ended September 30, 2010
(unaudited) and 2011 (unaudited).
At
December 31, 2009 and September 30, 2011 (unaudited), no single customer accounted for more than 10% of total accounts receivable. At December 31, 2010, the

As
of December 31, 2009, 2010 and September 30, 2011 (unaudited), all investments mature in less than one year. Estimated fair values for marketable securities are based on
quoted market prices for the same or similar instruments.
Fair Value Measurements
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit
price") in an orderly transaction between market participants at the measurement date. A hierarchy for inputs used in measuring fair value has been defined to minimize the use of unobservable inputs
by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data.
Unobservable inputs are inputs that reflect the Company's assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in
the circumstances.
The
fair value hierarchy prioritizes the inputs into three broad levels:
•
Level 1 Quoted (unadjusted) prices in active markets for identical assets or liabilities.
The
Company's Level 1 assets consist of money market funds, and a certificate of deposit.
•
Level 2 Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar
assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by
observable market data for substantially the full term of the asset or liability.
The
Company's Level 2 assets and liabilities consist of corporate bonds and agency debt securities.
•
Level 3 Unobservable inputs to the valuation methodology that are supported by little or no market activity and
that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing
models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation.

Operating Leases
The Company leases certain of its facilities under noncancelable operating leases with various expiration dates through June 2014.
Rent
expense was $1,001, $1,117, $1,157, $853 (unaudited) and $1,084 (unaudited) for the years ended December 31, 2008, 2009 and 2010 and for the nine months ended
September 30, 2010 and 2011, respectively.
Capital Leases
The Company acquired capital leases as part of the EDN acquisition. The leases were secured by fixed assets primarily used in a data
center. The leases have various expiration dates through October 2012. The interest rates range from 2.9% to 10.6%.
At
December 31, 2010, future annual minimum lease payments under noncancelable operating and capital leases were as follows:

Contingencies
Under the indemnification provisions of the Company's customer agreements, the Company agrees to indemnify and defend and hold harmless
its customers against, among other things, infringement of any patent, trademark or copyright under any country's laws or the misappropriation of any trade secret arising from the customers' legal use
of the Company's solutions. The exposure to the Company under these indemnification provisions is generally limited to the total amount paid by the customers under the applicable customer agreement.
However, certain indemnification provisions potentially expose the Company to losses in excess of the aggregate amount paid to the Company by the customer
F-26

under
the applicable customer agreement. To date, there have been no claims against the Company or its customers pursuant to these indemnification provisions.
Legal Contingencies
From time to time, the Company is involved in claims and legal proceedings that arise in the ordinary course of business. Based on
currently available information, management does not believe that the ultimate outcome of these unresolved matters, individually and in the aggregate, is likely to have a material adverse effect on
the Company's financial position, results of operations or cash flows. However, litigation is subject to inherent uncertainties and the Company's view of these matters may change in the future. Were
an unfavorable outcome to occur, there exists the possibility of a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the
unfavorable outcome occurs, and potentially in future periods.
8. Debt
Equipment Financing Loans
The Company entered into a new equipment loan agreement with Silicon Valley Bank in April 2011 for an aggregate loan principle amount
of $6,000. Interest on the advances are equal to prime rate plus 0.50%. As of September 30, 2011, the interest on the advances was 4.50%. The Company has the ability to draw down on this
equipment line through April 19, 2012. Each drawn amount is due 48 months after funding. Borrowings outstanding under the equipment loan at September 30, 2011 were $2,926
(unaudited). Equipment financed under this loan arrangement is collateralized by the respective assets underlying the loan. The terms of the loan restrict the Company's ability to pay dividends. The
loan includes a covenant that requires the Company to maintain cash and cash equivalents plus net accounts receivables of at least two times the amount of all outstanding indebtedness. As of
September 30, 2011 (unaudited), the Company was in compliance with the financial covenant.
The
Company had a previous equipment loan arrangement with Silicon Valley Bank for $2,000. The loan bore interest at an annual rate of 8.75%. The maturity date was 36 months after
the funding date. Borrowings outstanding under the equipment loan at December 31, 2010 and September 30, 2011 were $67 and $0 (unaudited), respectively. Equipment financed under this
loan arrangement was collateralized by the respective assets underlying each specific draw down. This loan required the Company to maintain a tangible net worth greater than $18,000. As of
December 31, 2010, the Company was in compliance with the financial covenant.
Interest
expense for the years ended December 31, 2008, 2009 and 2010 and the nine months ended September 30, 2010 and 2011 was approximately $85, $48, $27, $25 (unaudited)
and $37 (unaudited), respectively.

In
October 2009, the Company entered into an amendment to the Series F preferred stock Purchase agreement and issued 940 shares of Series F preferred stock at $5.32 per
share, to an existing investor, for cash proceeds of $5,000 net of issuance costs of $38. Additionally, the Company issued 188 shares of Series F preferred stock, as part of the consideration
paid for the acquisition of EDN, see Note 2.
In
May 2010, the Company entered into a second amendment to the Series F preferred stock Purchase agreement and issued 282 shares of Series F preferred stock at $5.32 per
share to an existing investor, for cash proceeds of $1,500 net of issuance costs of $9.
The
preferred stock has certain rights, preferences, privileges and restrictions with respect to voting, dividends, liquidation and conversion as follows:
Voting
Each share of the preferred stock has the same voting rights as the number of shares of common stock into which it is convertible.

9. Preferred Stock (Continued)
Dividends
The holders of Series A, B, C, D, E and F preferred stock are entitled to receive noncumulative dividends prior and in
preference to any declaration or payment of any dividend on the common stock of the Company, at the per annum rate of $0.08, $0.1024, $0.1926, $0.2408, $0.2786 and $0.4256 per share, respectively,
when and if declared by the Board of Directors. Dividends on preferred stock or common stock have never been declared by the Board of Directors.
Liquidation
In the event of liquidation, dissolution or winding-up of the Company, either voluntary or involuntary, the holders of the
preferred stock are entitled to receive, prior to and in preference to any distribution of any of the assets of the Company to the holders of common stock by reason of ownership thereof, an amount per
share equal to $1.00, $1.28, $2.41, $3.01, $3.48 and $5.32 plus any declared but unpaid dividends to the holders of Series A, B, C, D, E and F preferred stock, respectively. If the assets and
funds distributed among the holders of Series A, B, C, D, E and F preferred stock are insufficient to permit the payment to such holders of the full amounts, then the entire assets and funds of
the Company shall be distributed ratably among the holders of Series A, B, C, D, E and F preferred stockholders. The remaining assets, if any, shall be distributed to the common stockholders.
These liquidity features cause the Company's convertible preferred stock to be classified as mezzanine equity rather than as a component of stockholders' deficit.
Conversion
Each share of Series A, B, C, D, E and F preferred stock is convertible at the option of the holder into such number of shares
of common stock as is determined by dividing $1.00, $1.28, $2.41, $3.01, $3.48 and $5.32, respectively, by the conversion price applicable to such share, determined in effect on the date the
certificate is surrendered for conversion. The conversion price for each share of Series A, B, C, D, E and F preferred stock was $1.00, $1.28, $2.41, $2.41, $3.47, and $5.32, respectively. Such
initial conversion price shall be subject to adjustment for stock splits, reverse stock splits, stock dividends and other matters. Each share of Series A, B, C and F preferred stock is
convertible on a 1:1 basis into common stock. Series D preferred stock is convertible into 1.25 shares of common stock and each share of Series E preferred stock is convertible into
1.00463 shares of common stock. The shares of preferred stock are automatically converted into shares of common stock at the conversion price in effect upon the earlier of a closing of an initial
public offering of common stock in which the gross proceeds exceeds $40,000 and in which the public offering price per share equals or exceeds $10.64 per share, or the date specified by the holders of
a majority of the outstanding shares of the preferred stock.
Redemption
The convertible preferred stock is not redeemable by the Company or at the option of the preferred stockholders.

Series B Preferred Stock Warrants
In 2004, the Company issued warrants to purchase 78 shares of the Company's Series B convertible preferred stock at a price of
$1.28 per share in connection with an equipment financing arrangement. Using the Black-Scholes option-pricing model, the Company determined the fair value of each warrant to be $1.07 and $2.01 as of
December 31, 2009 and 2010, respectively. The fair value of the warrants was estimated using the following assumptions.

10. Common Stock
The Company's Certificate of Incorporation, as amended on October 19, 2009, authorizes the Company to issue 70,000 shares of $0.0001 par value common stock. The Company had
repurchased 326 shares of common stock prior to 2009, which had been early exercised, which were pending retirement at December 31, 2010 and 2009. Accordingly 6,924, 7,968 and 8,593 (unaudited)
shares of common stock were issued and 6,598, 7,657 and 8,268 (unaudited) shares of common stock were outstanding at December 31, 2009 and 2010 and September 30, 2011, respectively.
A
portion of the shares sold are subject to a right of repurchase by the Company subject to vesting, which is generally over a four year period from the earlier of grant date or employee
hire date, as applicable, until vesting is complete. There was no repurchase of common stock during the years ended December 31, 2009 and 2010 and the nine months ended September 30,
2011 (unaudited). At December 31, 2009 and 2010 and September 30, 2011 (unaudited), there were 14, 10 and 5 shares, respectively, subject to repurchase.
The
Company had, prior to 2009, granted a warrant to a service provider to purchase 4 shares of common stock in exchange for services performed. Such warrant for common stock issued by
the Company is outstanding at September 30, 2011 (unaudited).
11. Stock Option Plan
Under the Company's 2002 stock option plan (the "Plan"), the Company may grant options to purchase common stock or directly issue shares of common stock to employees, outside directors
and consultants at prices equal to the fair market value at the date of grant of options or issue of common stock. The Company has the right to repurchase any unvested shares (at the option exercise
price) of common stock issued directly or under option exercises. The right of repurchase generally expires over the vesting period.

Under
the 2002 Plan, the term of an option grant shall not exceed ten years from the date of its grant and options generally vest over a three to four-year period, with
vesting on a monthly or annual interval. 28,555 shares of common stock are reserved for issuance to eligible participants, under the 2002 Plan. As of December 31, 2009 and 2010,
September 30, 2011, 508 shares, 52 shares and 1,558 (unaudited) shares, respectively, were available for future grants.

respectively,
and cash proceeds from such option exercises were $175, $209, $1,211 and $861 (unaudited).
Stock-Based Compensation
The fair value of options granted is estimated on the grant date using the Black-Scholes option valuation model. This valuation model
for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time
that the options granted are expected to be outstanding), the volatility of the common stock price, an assumed risk-free interest rate and the estimated forfeitures of unvested stock
options. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded
for options that do not vest and the compensation cost from vested options, whether forfeited or not, is not reversed.
The
Board of Directors determined the fair market values of the Company's common stock, in good faith and based on the best information available to the Board and the Company's
management at the time of grant. The Company performed its analysis in accordance with applicable elements of the
practice aid issued by the American Institute of Certified Public Accountants entitled
Valuation of Privately Held Company Equity Securities Issued as
Compensation
. The procedures performed to determine the fair value of the Company's common stock was based on a probability-weighted expected return method to estimate the
aggregate equity value of the Company.
The
weighted average fair value of stock options granted to employees during the years ended December 31, 2008, 2009, 2010 and the nine months ended September 30, 2011, was
$2.16, $1.57, $2.29 and $2.79 (unaudited), respectively. The fair values were estimated on the grant dates using the Black-Scholes option-pricing model with the following weighted-average assumptions:

The
estimate for expected term of options granted reflect the midpoint of the vesting term and the contractual life computed with the simplified method outlined in SAB 107C
(SAB 107). The Company does not have significant historical share option exercise experience and hence considers the expected term assumption calculated using the simplified method to be
reasonable. Since the Company's stock is not publicly traded, the stock volatility assumptions represent an estimate of the historical volatilities of the common stock of a group of publicly-traded
peer companies that operate in a similar industry. The estimate was determined based on the average historical volatilities of these peer companies. The risk-free interest rate used was
the Federal Reserve Bank's constant maturities interest rate commensurate with the expected life of the options in effect at the time of the grant. The expected

dividend
yield was zero, as the Company does not anticipate paying a dividend within the relevant time frame. Expected forfeitures are estimated based on the Company's historical experience.
The
Company realized no income tax benefit from stock option exercises in each of the periods presented due to recurring losses and valuation allowances.
As
of September 30, 2011, the Company had unamortized stock-based compensation expense of $9,431 (unaudited) related to stock options, that will be recognized net of forfeitures
over the average remaining vesting term of the options of 2.97 (unaudited) years.
Stock Reserved for Issuance
As of December 31, 2010 and September 30, 2011 (unaudited), the Company has reserved common stock for issuance of the

During
the year ended December 31, 2009, the Company re-priced options granted to 62 employees with an exercise price of $2.28 per share and granted new options at a
fair value of $1.53 per share to vest over four years. The incremental expense of $541 relating to such re-pricing of options is being recorded over the new vesting term of the options.
12. Net Loss per Share
Our basic net loss per share of common stock is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period. The
weighted-average number of shares of common stock used to calculate our basic net loss per share of common stock excludes those shares subject to repurchase related to stock options that were
exercised prior to vesting as these shares are not deemed to be issued for accounting purposes until they vest. The diluted net loss per share of common stock is computed by dividing the net loss
using the weighted-average
number of shares of common stock, excluding common stock subject to repurchase, and, if dilutive, potential shares of common stock outstanding during the period. Potential shares of common stock
consist of common stock subject to repurchase and stock options to purchase common stock and warrants to purchase convertible preferred stock (using the treasury stock method) and the conversion of
our convertible preferred stock and convertible notes payable (using the "if converted" method).

Pro forma basic and diluted net loss per share of common stock has been computed to give effect to the conversion of the convertible preferred stock into common stock as of the later of
January 1, 2010 or the issuance date. As discussed in Note 9, the warrants to purchase preferred stock were exercised on a net settlement basis in August 2011. For purposes of this pro
forma presentation of basic and diluted net loss per share of common shares (unaudited), the Company has assumed that the preferred stock warrants were exercised on a net settlement basis on
January 1, 2010. Also, the numerator in the pro forma basic and diluted net loss per share calculation has been adjusted to remove gains and losses resulting from remeasurements of the
convertible preferred stock warrant liability.

14. Segment Reporting
Operating segments are reported in a manner consistent with the internal reporting provided to, and defined as components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating
decision maker is its chief executive officer. The Company's chief executive officer reviews financial information presented on a consolidated basis and as a result, the Company concluded that there
is only one operating and reportable segment.

Realization
of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets have been fully
offset by a valuation allowance. The valuation allowance increased by approximately $12,700, $5,600 and $8,200 during December 31, 2008, 2009 and 2010, respectively.
As
of December 31, 2009 and 2010, the Company had net operating loss carryforwards for federal income tax purposes of approximately $85,000 and $90,400, respectively. The net
operating losses will
F-37

begin
to expire in the year 2018. As of December 31, 2009 and 2010, the Company had research credits for federal income tax purposes of approximately $2,000 and $2,700, respectively. The
research and development credits will begin to expire in the year 2022. In addition, as of December 31, 2009 and 2010, the Company had net operating loss carryforwards and research and
development tax credits for state income tax purposes of approximately $72,000 and $77,900 respectively. The state net operating loss carryforwards expire at varying amounts beginning in the year
2011. As of December 31, 2009 and 2010, the Company had state research and development carryforwards of $2,500 and $3,200 which will carryforward indefinitely.
Utilization
of the net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state
provisions. An analysis was conducted through 2009 to determine whether an ownership change had occurred since inception. The analysis indicated that although an ownership change occurred in a prior
year, the net operating losses and research and development credits would not expire before utilization. In the event the Company has subsequent changes in ownership, net operating losses and research
and development credit carryovers could be limited and may expire unutilized.
Effective
January 1, 2009, the Company adopted the provisions of FASB's guidance on accounting for uncertainty in income taxes. This provides a comprehensive model for the
recognition, measurement and disclosure in financial statements of uncertain income tax positions that a company has taken or expects to take on a tax return. Under these provisions, a company can
recognize the benefit of an income tax position only if it is more likely than not (greater than 50%) that the tax position will be sustained upon tax examination, based solely on the technical merits
of the tax position. Otherwise, no benefit can be recognized. Assessing an uncertain tax position begins with the initial determination of the position's sustainability and is measured at the largest
amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain
tax positions must be reassessed. Additionally, companies are required to accrue interest and related penalties, if applicable, on all tax exposures for which reserves have been established consistent
with jurisdictional tax laws. The cumulative effect of this adoption is recorded as an adjustment to the opening balance of its accumulated deficit on the adoption date.
As
a result of the implementation of these provisions, the Company recognized a $820 increase in its unrecognized tax benefits. There was no increase in the January 1, 2009
balance of accumulated deficit since the benefit relates to attribute carryovers for which the related deferred tax asset was subject to a full valuation allowance. At the adoption date of
January 1, 2009 and as of December 31, 2010, the Company had no accrued interest or penalties related to the tax contingencies. Since the unrecognized tax benefit relates to attribute
carryovers for which the deferred tax asset was subject to a full valuation allowance, the recognition of the unrecognized tax benefits will not affect the Company's effective tax rate. The Company
has elected to recognize interest and penalties as a component of income tax expense. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at
December 31, 2010 will significantly increase or decrease within the next twelve months. Because of net operating loss and credit carryforwards, all of the Company's tax years, dating to
inception in 2002 remain open to tax examination in all major tax jurisdictions.

U.S.
income and foreign withholding taxes associated with the repatriation of earning of foreign subsidiaries have not been provided on undistributed earnings for certain foreign
subsidiaries. The Company intends to reinvest these earnings indefinitely outside the United States. As of December 31, 2010, the Company estimates that no material additional U.S. income or
foreign withholding taxes would have to be provided if these earnings were repatriated back to the United States.
16. Subsequent Events

ITEM 14.   Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation's board of directors to grant,
indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the Delaware General Corporation Law are sufficiently broad to
permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended, or Securities Act.
As
permitted by the Delaware General Corporation Law, the Registrant's restated certificate of incorporation contains provisions that eliminate the personal liability of its directors
for monetary damages for any breach of fiduciary duties as a director, except for liability:
•
for any breach of the director's duty of loyalty to the Registrant or its stockholders;
•
for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
•
under Section 174 of the Delaware General Corporation Law (regarding unlawful dividends, stock purchases or
redemptions); or
•
for any transaction from which the director derived an improper personal benefit.
As
permitted by the Delaware General Corporation Law, the Registrant's restated bylaws provide that:
•
the Registrant is required to indemnify its directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to very limited exceptions;
•
the Registrant may indemnify its other employees and agents as set forth in the Delaware General Corporation Law;
II-1
Table of Contents
•
the Registrant is required to advance expenses, as incurred, to its directors and officers in connection with a legal
proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions; and
•
the rights conferred in the bylaws are not exclusive.
Prior
to the closing of the offering that is the subject of this Registration Statement, the Registrant intends to enter into indemnification agreements with each of its current
directors and executive officers to provide these directors and executive officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant's restated
certificate of incorporation and restated bylaws and to provide additional procedural protections. At present, there is no pending litigation or proceeding involving a director, executive officer or
employee of the Registrant regarding which indemnification is sought. Reference is also made to Section 8 of the Underwriting Agreement, which provides for the indemnification of executive
officers, directors and controlling persons of the
Registrant against certain liabilities. The indemnification provisions in the Registrant's restated certificate of incorporation and restated bylaws and the indemnification agreements entered into or
to be entered into between the Registrant and each of its directors and executive officers is sufficiently broad to permit indemnification of the Registrant's directors and executive officers for
liabilities arising under the Securities Act.
The
Registrant has directors' and officers' liability insurance for securities matters.

June 23, 2011, the Registrant issued 48,886 shares of its Series B preferred stock upon exercise of warrants issued by the Registrant in

The
sales of the securities described in paragraphs (1) - (3) above were deemed to be exempt from registration under the Securities Act in reliance upon
Section 4(2) of the Securities Act. The recipients of the securities in these transactions represented their intentions to acquire the securities for investment only and not with a view to or
for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates issued in these transactions. All such recipients represented that they were
accredited investors or, together with their purchaser representative, otherwise satisfied applicable requirements. The issuances and sales of the securities described in
paragraphs (4) - (5) above were deemed to be exempt from registration under the Securities Act in reliance upon Rule 701 promulgated under Section 3(b) of the
Securities Act as transactions pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. None of the foregoing transactions involved any underwriters,
underwriting discounts or commissions, or any public offering.
ITEM 16.    Exhibits and Financial Statement Schedules.
(a)    Exhibits.
See Exhibit Index immediately following the Signature Pages.
(b)    Financial Statement Schedules.
All financial statement schedules are omitted because they are not applicable or the information is included in the Registrant's
consolidated financial statements or related notes.
ITEM 17.    Undertakings.
The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreements
certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to provisions
described in Item 14 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
