appropriate classification of marketable securities at the time of purchase and reevaluates its designation as of each balance sheet date. All marketable securities owned during the three and nine months ended September&nbsp;30, 2010 and 2009 were
classified as available for sale. Interest and dividend income on investments in marketable securities are included in &#147;Interest income.&#148; The cost of securities sold is based on the specific identification method. Investments in marketable
securities are recorded as of each balance sheet date at fair value, with unrealized gains and, to the extent deemed temporary, unrealized losses in stockholders&#146; equity. Accretion of discounts and amortization of premiums and realized gains

investments in marketable securities. In the event that the cost basis of a security exceeds its fair value, the Company evaluates, among other factors, the amount and duration of the period that the fair value is less than the cost basis, the
financial health of and business outlook for the issuer, including industry and sector performance, and operational and financing cash flow factors, overall market conditions and trends, the Company&#146;s intent to sell the investment and whether
it is more likely than not the Company would be required to sell the investment before its anticipated recovery. If a decline in fair value is determined to be other-than-temporary, the Company records an impairment charge in the statement of
operations and establishes a new cost basis in the security. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; margin-left:2%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B><I>Revenue Recognition </I></B></FONT></P>

accounting. If the arrangement constitutes separate units of accounting according to the separation criteria of ASC 605-25, a revenue recognition policy must be determined for each unit. If the arrangement constitutes a single unit of accounting,
the revenue recognition policy must be determined for the entire arrangement. </FONT></P>

expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the results of operations in
the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely </FONT></P>

expected to be taken in a tax return. ASC 740 requires interim income tax expense or benefit to be calculated using an estimated annual effective tax rate, unless the taxpayer&#146;s best estimate of the annual effective tax rate is the actual
year-to-date tax rate. The Company&#146;s effective income tax rates for each of the three and nine months ended September&nbsp;30, 2010 was the Company&#146;s actual year-to-date effective tax rate. ASC 740 also provides guidance on de-recognition,
classification, interest and penalties, accounting in interim periods, disclosures and transition. The Company&#146;s policy is to classify any interest recognized in accordance with ASC 740 as interest expense and to classify any penalties
recognized in accordance with ASC 740 as an expense other than income tax expense. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; margin-left:2%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B><I>Net Income (Loss) Per Share

<P STYLE="margin-top:0px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As of September&nbsp;30, 2010, several of the Company&#146;s investments in marketable securities were in an unrealized loss position for a duration of
less than 12 months. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As of December&nbsp;31, 2009, the Company&#146;s investments in marketable securities consisted of certificates of
deposit of $27,000,000 and accrued interest of $157,000 for which amortized cost approximated fair value. The Company&#146;s investments in marketable securities, including those classified on its balance sheet as cash equivalents, reach maturity
between October&nbsp;21, 2010 and May&nbsp;20, 2013, with a weighted average maturity date of approximately September&nbsp;30, 2011. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>4.
Income Taxes </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">For the three and nine months ended September&nbsp;30, 2010, the Company recognized $257,000 and $2,395,000, respectively, of
income tax expense primarily as a result of the application of ASC 740 to stock-based compensation. Exercises of stock options during the three and nine months ended September&nbsp;30, 2010 resulted in tax deductions for stock-based compensation in
excess of expense recorded for the stock options under GAAP, resulting in income tax benefits of $160,000 and $2,278,000, respectively. The Company recognized the income tax benefit related to the excess tax deductions as an increase to capital in
excess of par value, which based on ASC 740 resulted in an offsetting charge in the same amount to income tax expense. Exercises of stock options in prior periods resulted in $5,716,000 in tax deductions in excess of expense recorded for the stock
options under GAAP. Because these excess deductions occurred in periods for which there were no income taxes payable, the tax benefit will not be recognized as an increase to capital in excess of par value unless and until the excess deductions are
used to reduce income taxes payable. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">For the three and nine months ended September&nbsp;30, 2010, gross unrecognized tax benefits decreased
by $278,000 and $411,000, respectively, as a result of settlements with taxing authorities. Because the Company has incurred cumulative net operating losses since inception, all tax years remain open to examination by major jurisdictions. An
examination of the Company&#146;s 2006 federal income tax return was completed in 2009 with no adjustments. An examination of the Company&#146;s 2007, 2006 and 2005 North Carolina income tax returns was completed in March 2010 and did not result in
any adjustments that had a material impact on the Company&#146;s financial statements for any period. </FONT></P>

exclusive development and worldwide commercialization rights to the Company&#146;s product candidate known as AZD3480 (TC-1734) as a treatment for specified conditions characterized by cognitive impairment, including attention deficit/hyperactivity
disorder, or ADHD. The Company is eligible to receive license fees and milestone payments under the agreement. The amount of license fees and milestone payments depends on the timing and achievement of development, regulatory, first commercial sale
and first detail milestone events. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">AstraZeneca paid the Company an initial fee of $10,000,000 in February 2006. Based on the agreement terms,
the Company allocated $5,000,000 of the initial fee to the research collaboration, which the Company recognized as revenue on a straight-line basis over the four-year term of the research collaboration. The Company deferred recognition of the
remaining $5,000,000 of the initial fee, which was allocated to the AZD3480 license grants, until December 2006, when AstraZeneca made a determination to proceed with further development of AZD3480 following the completion of additional clinical and
non-clinical studies that AstraZeneca conducted during 2006. On December&nbsp;27, 2006, AstraZeneca communicated its decision to proceed with further development of AZD3480 to the Company. As a result, in the first quarter of 2007, the Company began
recognizing the $5,000,000 of the initial fee that it had previously deferred as revenue on a straight-line basis over the estimated five-year development period for AZD3480. In July 2009, the Company announced that it had been informed by
AstraZeneca of AstraZeneca&#146;s plans to conduct further development of AZD3480 for ADHD. The Company extended its estimate of the development period for AZD3480 to continue through 2013 and began recognizing the part of the $5,000,000 portion of
the initial fee not yet recognized as of April&nbsp;1, 2009 as revenue on a straight-line basis over the remaining estimated development period. The Company recognized $145,000 and $457,000 of the initial fee as revenue for three months ended
September&nbsp;30, 2010 and 2009, respectively, and $538,000 and $1,477,000 of the initial fee as revenue for the nine months ended September&nbsp;30, 2010 and 2009, respectively. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT

to develop TC-5619 independently through completion of Phase 1 clinical development and a Phase 2 clinical proof of concept clinical trial in accordance with a mutually acceptable development plan, following which AstraZeneca would have the right to
license TC-5619 on terms specified in the agreement. The Company is recognizing the $2,000,000 payment as revenue on a straight-line basis over the estimated period of the Company&#146;s research and development obligations for TC-5619. Accordingly,
the Company recognized $43,000 and $122,000 of the payment as revenue for the three months ended September&nbsp;30, 2010 and 2009, respectively, and $235,000 and $474,000 of the payment as revenue for the nine months ended September&nbsp;30, 2010

the terms applicable to TC-5619. In conjunction with the amendment, the Company and AstraZeneca agreed to an expanded development program for TC-5619 and the Company received a payment of $11,000,000 to maintain AstraZeneca&#146;s future option to
license TC-5619. The Company recorded the $11,000,000 payment as deferred revenue and is recognizing it as revenue on a straight-line basis over the estimated period of the Company&#146;s research and development obligations for TC-5619. The Company
recognized $2,357,000 and $3,929,000 of the payment as revenue for the three and nine months ended September&nbsp;30, 2010, respectively. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As
part of the expanded TC-5619 development program, the Company has two Phase 2 clinical proof of concept trials ongoing, one in cognitive dysfunction in schizophrenia, or CDS, and one in ADHD. The Company also agreed to conduct specified clinical and
non-clinical studies, and AstraZeneca agreed to conduct other specified non-clinical studies, to support the potential advancement of TC-5619 into Phase 2 clinical development for Alzheimer&#146;s disease. A decision as to whether to conduct Phase 2
clinical development of TC-5619 for Alzheimer&#146;s disease would be made in the future. If TC-5619 has been licensed by AstraZeneca or remains subject to AstraZeneca&#146;s license option, any Phase 2 clinical development for Alzheimer&#146;s
disease would be funded by AstraZeneca. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">Under the agreement, AstraZeneca has an option for an exclusive license to TC-5619 for various

clinical and non-clinical studies related to Alzheimer&#146;s disease if TC-5619 does not achieve clinical proof of concept in CDS or ADHD. If AstraZeneca exercises its option, it would pay the Company an exercise fee of $30,000,000 and assume
responsibility for and fund all future development and commercialization for TC-5619 beyond the currently agreed upon development program. In that event, the Company would be eligible to receive additional payments of up to $212,000,000, if
development, regulatory, first commercial sale and first detail milestone events for TC-5619 are achieved in three indications, and stepped double-digit royalties on any future TC-5619 product sales for any indication. If AstraZeneca does not
exercise its option the first time that TC-5619 achieves clinical proof of concept, whether in CDS, ADHD or Alzheimer&#146;s disease, or if TC-5619 achieves clinical proof of concept in neither CDS nor ADHD and AstraZeneca disclaims any further
interest, the Company would retain all of its rights in TC-5619. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company has also received payments under the agreement that it
recognized in full as revenue upon achievement of the corresponding milestone event because the event met each of the conditions required for immediate recognition under its revenue recognition policy (see Note 2). In particular, the Company
received a $10,000,000 payment from AstraZeneca in July 2009 based on achievement of the objective in a completed Phase 2 clinical trial of AZD3480 in adults with ADHD, a milestone event under an amendment to the agreement. The Company made a
payment of $350,000 to UKRF in December 2009 as a result of the $10,000,000 payment received from AstraZeneca. The Company has also received cumulative payments from AstraZeneca of $2,400,000 based on the achievement of milestone events related to
the development of product candidates arising under the parties&#146; completed preclinical research collaboration, including AZD1446. </FONT></P>

sale milestone events for TC-5214 are achieved, cumulative payments of up to an additional $500,000,000 if specified sales related milestone events for TC-5214 are achieved and significant stepped double-digit royalties on net sales of TC-5214
worldwide. The Company recorded the upfront payment made by AstraZeneca as deferred revenue and is recognizing the payment as revenue on a straight-line basis over the estimated period of the Company&#146;s substantive performance obligations under
the agreement, or approximately 33 months. The Company recognized $18,290,000 and $54,274,000 of the upfront payment as revenue for the three and nine months ended September&nbsp;30, 2010, respectively. The Company would recognize as revenue the
full amount of each payment received based on the achievement of milestone events under the agreement upon its achievement if the Company determines that the revenue satisfies the requirements for immediate recognition under its revenue recognition
policy (see Note 2). </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Company and AstraZeneca have jointly designed a program for the global development of TC-5214. The initial program
is planned to include development of TC-5214 as an adjunct therapy and as a second-line &#147;switch&#148; monotherapy, in each case in patients with major depressive disorder who do not respond adequately to first-line antidepressant treatment.
AstraZeneca is responsible for 80% and the Company is responsible for 20% of the costs of the initial program, except that AstraZeneca is responsible for 100% of development costs that are required only to obtain or maintain regulatory approval in
countries outside the United States and the European Union. The Company has the right to terminate its obligation to fund its share of the costs of the initial program once it has funded a specified amount. In addition, for each of the Company and
AstraZeneca, costs that were not contemplated at execution to be part of the initial program may in some cases be excluded from the cost-sharing arrangement. If the Company funds the specified amount and terminates its obligation to fund its share
of further costs of the initial program, any future milestones and royalties payable to the Company under this agreement would be reduced by the amount of the Company&#146;s unfunded share plus interest at a specified rate, subject to a maximum
reduction that may be applied to any one payment. In addition, if the Company and AstraZeneca mutually agree to develop TC-5214 for any indication other than major depressive disorder or in any formulation other than those contemplated by the
initial program, the same cost-sharing arrangement would apply, except that the Company would have the immediate right to terminate its obligation to fund its share of development costs for the other indication or formulation. If the Company
terminates its obligation to fund its share of these other development costs, any future milestones and royalties payable to the Company under this agreement would be reduced by the amount of the Company&#146;s unfunded share plus interest at a
specified rate, subject to a maximum reduction that may be applied to any one payment, but only from and after the occurrence of a specified event to be agreed upon by the parties. </FONT></P>

recognizing these deferred amounts into revenue over the periods discussed in Note 5 to our unaudited financial statements included in this quarterly report. As of September&nbsp;30, 2010, we had $28.8 million of the deferred amounts remaining to be

preclinical research involving the use of compounds that modulate NNRs to address Levodopa-induced abnormal involuntary movements, known as dyskinesias, and we have received aggregate payments of $641,000 from MJFF since August 2009 in connection
with this grant. The other grant is to fund research to identify NNR-related biomarkers relevant to Parkinson&#146;s disease, and we expect to receive an aggregate of $304,000 from MJFF over a one-year period that began in December 2009 in
connection with this grant. In addition, as of September&nbsp;30, 2010, we are a named subcontractor under a grant awarded to The California Institute of Technology by the National Institute on Drug Abuse, or NIDA, part of the National Institutes of

taxes for any period through December&nbsp;31, 2009. We expect that we may incur taxable income, before giving effect to net operating loss carryforwards, for the year ending December&nbsp;31, 2010. For the three and nine months ended
September&nbsp;30, 2010, we recognized $257,000 and $2.4 million, respectively, of income tax expense primarily as a result of the application of Accounting Standards Codification Topic 740, <I>Income Taxes,</I> or ASC 740, to stock-based
compensation. Exercises of stock options during the three and nine months ended September&nbsp;30, 2010 resulted in tax deductions for stock-based compensation in excess of expense recorded for the stock options under U.S. generally accepted
accounting principles, or GAAP, resulting in income tax benefits of $160,000 and $2.3 million, respectively. We recognized the income tax benefit related to the excess tax deductions as an increase to capital in excess of par value, which based on
ASC 740 resulted in an offsetting charge in the same amount to income tax expense. As of September&nbsp;30, 2010, we had net operating loss carryforwards of $66.0 million for federal income tax purposes and $76.8 million for state income tax
purposes. We also had research and development income tax credit carryforwards of $7.4 million for federal income tax purposes and $595,000 for state income tax purposes as of September&nbsp;30, 2010. The federal net operating loss carryforwards
begin to expire in 2020. The state net operating loss carryforwards begin to expire in 2015. The federal and state research and development tax credits begin to expire in 2021. As a result of various factors, including the subjectivity of
measurements used in the calculation of particular tax positions taken or that may in the future be taken in our tax returns, it is uncertain whether or to what extent we will be eligible to use the tax credits. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to ownership change
limitations provided by Section&nbsp;382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. When an ownership change, as defined by Section&nbsp;382, occurs, an annual limitation is imposed on a company&#146;s use of net
operating loss and credit carryforwards attributable to periods before the change. As a result of a series of stock issuances, we had such an ownership change in November 2002. Consequently, an annual limitation is imposed on our use of net
operating loss and credit carryforwards that are attributable to periods before November 2002. In addition, a portion of the net operating loss carryforwards described above may potentially not be usable by us if we experience further ownership
changes in the future. For financial reporting purposes, we have recorded a valuation allowance to fully offset the deferred tax asset related to these carryforwards and the tax credits because the likelihood that we will be eligible to use or
realize any benefit from them is uncertain. </FONT></P>

compared to the three months ended September&nbsp;30, 2009. The higher net operating revenues were primarily attributable to an increase of $10.3 million in milestones and license fees from collaborations revenue, partially offset by a decrease of
$1.1 million in collaboration research and development revenue. The increase in milestones and license fees from collaborations revenue reflected recognition of $18.3 million of the $200.0 million upfront payment received under our TC-5214 agreement
with AstraZeneca, which we entered into in December 2009, and $2.4 million of the $11.0 million payment received under an April 2010 amendment to our cognitive disorders agreement with AstraZeneca to modify the terms applicable to TC-5619, partially
offset by achievement of a milestone event under our cognitive disorders agreement with AstraZeneca during the three months ended September&nbsp;30, 2009 for which we received $10.0 million and a decrease for the 2010 period of $313,000 of license
fees derived from the cognitive disorders agreement as a result of the expiration of the term of the preclinical research collaboration in January 2010. The decrease in collaboration research and development revenue for the 2010 period resulted from
the completion of the preclinical research collaboration under our cognitive disorders agreement with AstraZeneca. We plan to recognize the remaining $145.3 million of the upfront payment received under the TC-5214 agreement with AstraZeneca on a
straight-line basis over the estimated development period for TC-5214 to submission of a new drug application to the FDA and, as a result, expect to have higher net operating revenues for the year ending December&nbsp;31, 2010 as compared to the
year ended December&nbsp;31, 2009. As of September&nbsp;30, 2010, we forecast the new drug application submission date for TC-5214 to be approximately September&nbsp;30, 2012. We do not expect to record any collaboration research and development
revenue from the cognitive disorders agreement for the year ending December&nbsp;31, 2010 or any future period. </FONT></P>

administrative expenses for the three months ended September&nbsp;30, 2010 increased by $424,000 as compared to the three months ended September&nbsp;30, 2009. The higher general and administrative expenses were primarily attributable to an increase
of $407,000 in stock-based compensation, salary and other compensation-related expenses for general and administrative personnel to $1.2 million for the 2010 period from $776,000 for the 2009 period. The largest component of the increase was
stock-based compensation expense and was primarily due to a significantly higher fair value calculated for stock options granted during 2010 as compared to the fair value calculated for stock options granted during and prior to the 2009 period.

compared to the nine months ended September&nbsp;30, 2009. The higher net operating revenues were primarily attributable to an increase of $44.3 million in milestones and license fees from collaborations revenue, partially offset by a decrease of
$3.7 million in collaboration research and development revenue. The increase in milestones and license fees from collaborations revenue reflected recognition of $54.3 million of the $200.0 million upfront payment received under our TC-5214 agreement
with AstraZeneca and $3.9 million of the $11.0 million payment received under the April 2010 amendment to our cognitive disorders agreement with AstraZeneca, partially offset by the achievement of a milestone event under our cognitive disorders
agreement with AstraZeneca during the nine months ended September&nbsp;30, 2009 for which we received $10.0 million and decreases for the 2010 period of $2.5 million in aggregate payments received from GlaxoSmithKline upon achievement of milestone
events under our alliance agreement and $833,000 in license fees derived from the cognitive disorders agreement as a result of the expiration of the term of the preclinical research collaboration in January 2010. The decrease in collaboration
research and development revenue for the 2010 period resulted from the completion of the preclinical research collaboration under the cognitive disorders agreement with AstraZeneca. </FONT></P>

account any amounts that we would be entitled to receive if milestone events are achieved under either of our collaboration agreements with AstraZeneca or our alliance agreement with GlaxoSmithKline. However, our operating plan may change as a

coupled with other factors, may dramatically limit our access to additional equity or debt financing in the future on acceptable terms or at all. Also, additional strategic alliances, collaborations or licensing or other arrangements may not be
available on acceptable terms or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate our research and development programs or obtain funds through arrangements with collaborators or others that
may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently. Additionally, any future equity funding may dilute the ownership of our stockholders. </FONT></P>

investments without assuming significant risk. To achieve our objectives, we maintain a portfolio of cash equivalents and investments in marketable securities that are of high credit quality. As of September&nbsp;30, 2010, we had cash, cash
equivalents and investments in marketable securities of $268.0 million. Our investments may be subject to interest rate risk and could fall in value if market interest rates increase. However, because our cash equivalents are invested in accounts
with market interest rates and short term in nature and our investments in marketable securities are traded in active markets, we believe that our exposure to interest rate risk is not significant and estimate that an immediate and uniform 10%
increase in market interest rates from levels as of September&nbsp;30, 2010 would not have a material impact on the total fair value of our portfolio. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

NOTES TO UNAUDITED FINANCIAL STATEMENTS
September 30, 2010
1. The Company and Nature of Operations
Targacept, Inc., or the Company, is a Delaware corporation formed on March 7, 1997. The Company is a biopharmaceutical company engaged in the design, discovery and development of NNR
Therapeutics™ for the treatment of diseases and disorders of the nervous system. The Company's NNR Therapeutics selectively target neuronal nicotinic receptors, which it refers to as NNRs. Its facilities are located in Winston-Salem, North
Carolina.
2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited financial statements have been
prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company's audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31,
2009. In the opinion of the Company's management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of its financial position, operating results and cash flows for the periods presented have been
included. Operating results for the three and nine months ended September 30, 2010 and 2009 are not necessarily indicative of the results that may be expected for the full year, for any other interim period or for any future year.
Use of Estimates and Reclassifications
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues and expenses reported in the
financial statements and accompanying notes. Actual results could differ from these estimates.
Certain reclassifications have been made to
the financial statements for the nine months ended September 30, 2009 to conform to the presentation in the financial statements for the nine months ended September 30, 2010. These reclassifications had no impact on previously reported net
loss for any period.
Fair Value Measurement
The Company follows Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 820,
Fair Value Measurements and Disclosures
, or ASC 820, for application to
financial assets. ASC 820 defines fair value, provides a consistent framework for measuring fair value under GAAP and requires fair value financial statement disclosures. ASC 820 applies only to the measurement and disclosure of financial assets
that are required or permitted to be measured and reported at fair value under other ASC topics (except for ASC Topic 718,
Compensation – Stock Compensation
).

2. Summary of Significant Accounting Policies (continued)
The valuation techniques of ASC 820 are based on both observable and unobservable inputs. Observable inputs reflect readily obtainable data from
independent sources, and unobservable inputs reflect the Company's market assumptions. ASC 820 classifies these inputs into the following hierarchy:
Level 1 Inputs
– quoted prices (unadjusted) in active markets for identical assets that the reporting entity has the ability to access at the measurement date.
Level 2 Inputs
– inputs other than quoted prices included within Level 1 that are observable for the asset, either directly or indirectly.
Level 3 Inputs
– unobservable inputs for the asset.
The following tables present the Company's investments in marketable securities that are measured at fair value on a recurring basis as of September 30, 2010 and December 31, 2009,

September 30, 2010
2. Summary of Significant Accounting Policies (continued)
Investments in Marketable Securities
Consistent with the Company's investment policy, the Company's cash expected to be used to fund short-term liquidity requirements is invested with prominent financial institutions in bank
depository accounts, certificates of deposit and institutional money market funds and cash that the Company does not expect to need to fund its short-term liquidity requirements is invested in U.S. Treasury notes and bonds, U.S. federal and state
agency-backed certificates and corporate debt securities that are rated at least A quality or equivalent.
The Company determines the
appropriate classification of marketable securities at the time of purchase and reevaluates its designation as of each balance sheet date. All marketable securities owned during the three and nine months ended September 30, 2010 and 2009 were
classified as available for sale. Interest and dividend income on investments in marketable securities are included in "Interest income." The cost of securities sold is based on the specific identification method. Investments in marketable
securities are recorded as of each balance sheet date at fair value, with unrealized gains and, to the extent deemed temporary, unrealized losses in stockholders' equity. Accretion of discounts and amortization of premiums and realized gains
and losses are included in interest income in the statement of operations.
An investment in marketable securities is considered to be
impaired when a decline in fair value below its cost basis is determined to be other-than-temporary. The Company evaluates whether a decline in fair value below cost basis is other-than-temporary using available evidence regarding the Company's
investments in marketable securities. In the event that the cost basis of a security exceeds its fair value, the Company evaluates, among other factors, the amount and duration of the period that the fair value is less than the cost basis, the
financial health of and business outlook for the issuer, including industry and sector performance, and operational and financing cash flow factors, overall market conditions and trends, the Company's intent to sell the investment and whether
it is more likely than not the Company would be required to sell the investment before its anticipated recovery. If a decline in fair value is determined to be other-than-temporary, the Company records an impairment charge in the statement of
operations and establishes a new cost basis in the security.
Revenue Recognition
The Company uses the revenue recognition guidance established by ASC Topic 605,
Revenue Recognition
, or ASC 605. In determining the accounting for
collaboration and alliance agreements, the Company follows the provisions of Subtopic 25,
Multiple Element Arrangements,
of ASC 605, or ASC 605-25. ASC 605-25 provides guidance on whether an arrangement that involves multiple
revenue-generating activities or deliverables should be divided into separate units of accounting for revenue recognition purposes and, if this division is required, how the arrangement consideration should be allocated among the separate units of
accounting. If the arrangement constitutes separate units of accounting according to the separation criteria of ASC 605-25, a revenue recognition policy must be determined for each unit. If the arrangement constitutes a single unit of accounting,
the revenue recognition policy must be determined for the entire arrangement.

September 30, 2010
2. Summary of Significant Accounting Policies (continued)
Collaboration research and development revenue is earned and recognized as research is performed and related expenses are incurred. Non-refundable upfront
fees, which may include, for example, an initial payment upon commencement of the contractual relationship, payment representing a common stock purchase premium or payment to secure a right for a future license, are recorded as deferred revenue and
recognized into revenue as milestones and license fees from collaborations on a straight-line basis over (1) the estimated development period, to the extent the fees are attributable to a specific licensed product candidate, or otherwise
(2) the estimated period of the Company's substantive performance obligations or, where the Company's collaborator has substantially all research and development responsibility, over the estimated research and development period.
Revenue for non-refundable payments based on the achievement of collaboration milestones is recognized as revenue when the milestones are
achieved if all of the following conditions are met: (1) achievement of the milestone event was not reasonably assured at the inception of the arrangement; (2) substantive effort is involved to achieve the milestone event; and (3) the
amount of the milestone payment appears reasonable in relation to the effort expended, the other milestone payments in the arrangement and the related risk associated with achievement of the milestone event. If any of these conditions is not met,
the milestone payment is deferred and recognized on a straight-line basis over a period determined as discussed above.
Research and
development costs that are reimbursable under collaboration agreements are recorded in accordance with ASC 605, Subtopic 45,
Principal Agent Considerations
. Reimbursable amounts received under a cost-sharing arrangement are reflected as a
reduction of research and development expense.
Product sales revenue is recognized when goods are shipped, at which point title has passed,
net of allowances for returns and discounts. Revenue from a grant is recognized as the Company performs the work and incurs reimbursable costs in accordance with the objectives of the award. Grant payments received prior to the Company's
performance of work required by the terms of the award are recorded as deferred revenue and recognized as grant revenue as the Company performs the work and incurs qualifying costs.
Income Taxes
The
Company uses the liability method in accounting for income taxes as required by ASC Topic 740,
Income Taxes,
or ASC 740. Under ASC 740, deferred tax assets and liabilities are recorded for operating loss and tax credit carryforwards and for
the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the results of operations in
the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely

than not that the assets will be realized. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. ASC 740 requires interim income tax expense or benefit to be calculated using an estimated annual effective tax rate, unless the taxpayer's best estimate of the annual effective tax rate is the actual
year-to-date tax rate. The Company's effective income tax rates for each of the three and nine months ended September 30, 2010 was the Company's actual year-to-date effective tax rate. ASC 740 also provides guidance on de-recognition,
classification, interest and penalties, accounting in interim periods, disclosures and transition. The Company's policy is to classify any interest recognized in accordance with ASC 740 as interest expense and to classify any penalties
recognized in accordance with ASC 740 as an expense other than income tax expense.
Net Income (Loss) Per Share
The Company computes net income (loss) per share in accordance with ASC Topic 260,
Earnings Per Share
, or ASC 260. Under the
provisions of ASC 260, basic net income (loss) per share, or Basic EPS, is computed by dividing the net income (loss) by the weighted average number of common shares outstanding. Diluted net income (loss) per share, or Diluted EPS, is computed by
dividing the net income (loss) by the weighted average number of common shares and dilutive common share equivalents outstanding. The calculations of Basic EPS and Diluted EPS are set forth in the table below (in thousands, except share and per
share amounts):

Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options. For the nine
months ended September 30, 2009, the Company excluded all common share equivalents from the calculation of Diluted EPS because their effect is anti-dilutive. As a result, Diluted EPS is identical to Basic EPS for the nine months ended
September 30, 2009.

For the nine months ended September 30, 2009, shares subject to dilutive outstanding stock options may have been included in the calculation of
common share equivalents using the treasury stock method if the Company had been in a net income position. Shares subject to outstanding stock options that were anti-dilutive and consequently not included in the calculation of common share
equivalents totaled 923,313 and 17,380 for the three months ended September 30, 2010 and 2009, respectively, and 824,259 and 3,768,462 for the nine months ended September 30, 2010 and 2009, respectively, calculated on a weighted-average

2. Summary of Significant Accounting Policies (continued)
Intellectual Property
The Company capitalizes the costs of intellectual property acquired or licensed from external sources as intangible assets if, at the time of acquisition, the intellectual property has reached
technological feasibility. Intellectual property acquired or licensed from external sources that has not reached technological feasibility at the time of acquisition or that has no expected future use is charged to research and development expense
as incurred. The Company records all other charges related to the filing, prosecution and maintenance of patents to research and development expense as incurred.
Recent Accounting Pronouncements
In April 2010, the FASB issued Accounting
Standards Update No. 2010-17,
Milestone Method of Revenue Recognition,
or ASU 2010-17. ASU 2010-17 defines a milestone event and permits an entity to make an accounting policy election to recognize a payment that is contingent upon
achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. ASU 2010-17 is effective for fiscal years beginning on or after June 15, 2010, and for interim periods within those years, and may be
applied prospectively to milestones achieved after the adoption date or retrospectively for all periods presented. Early adoption is permitted. The Company does not expect ASU 2010-17 to have a material impact on its financial results.

3. Investments in Marketable Securities (continued)
As of September 30, 2010, several of the Company's investments in marketable securities were in an unrealized loss position for a duration of
less than 12 months.
As of December 31, 2009, the Company's investments in marketable securities consisted of certificates of
deposit of $27,000,000 and accrued interest of $157,000 for which amortized cost approximated fair value. The Company's investments in marketable securities, including those classified on its balance sheet as cash equivalents, reach maturity
between October 21, 2010 and May 20, 2013, with a weighted average maturity date of approximately September 30, 2011.
4.
Income Taxes
For the three and nine months ended September 30, 2010, the Company recognized $257,000 and $2,395,000, respectively, of
income tax expense primarily as a result of the application of ASC 740 to stock-based compensation. Exercises of stock options during the three and nine months ended September 30, 2010 resulted in tax deductions for stock-based compensation in
excess of expense recorded for the stock options under GAAP, resulting in income tax benefits of $160,000 and $2,278,000, respectively. The Company recognized the income tax benefit related to the excess tax deductions as an increase to capital in
excess of par value, which based on ASC 740 resulted in an offsetting charge in the same amount to income tax expense. Exercises of stock options in prior periods resulted in $5,716,000 in tax deductions in excess of expense recorded for the stock
options under GAAP. Because these excess deductions occurred in periods for which there were no income taxes payable, the tax benefit will not be recognized as an increase to capital in excess of par value unless and until the excess deductions are
used to reduce income taxes payable.
For the three and nine months ended September 30, 2010, gross unrecognized tax benefits decreased
by $278,000 and $411,000, respectively, as a result of settlements with taxing authorities. Because the Company has incurred cumulative net operating losses since inception, all tax years remain open to examination by major jurisdictions. An
examination of the Company's 2006 federal income tax return was completed in 2009 with no adjustments. An examination of the Company's 2007, 2006 and 2005 North Carolina income tax returns was completed in March 2010 and did not result in
any adjustments that had a material impact on the Company's financial statements for any period.

5. Strategic Alliance and Collaboration Agreements
AstraZeneca AB
Cognitive Disorders
In December 2005, the Company entered into a collaborative research and license agreement with AstraZeneca AB under which the Company granted AstraZeneca
exclusive development and worldwide commercialization rights to the Company's product candidate known as AZD3480 (TC-1734) as a treatment for specified conditions characterized by cognitive impairment, including attention deficit/hyperactivity
disorder, or ADHD. The Company is eligible to receive license fees and milestone payments under the agreement. The amount of license fees and milestone payments depends on the timing and achievement of development, regulatory, first commercial sale
and first detail milestone events.
AstraZeneca paid the Company an initial fee of $10,000,000 in February 2006. Based on the agreement terms,
the Company allocated $5,000,000 of the initial fee to the research collaboration, which the Company recognized as revenue on a straight-line basis over the four-year term of the research collaboration. The Company deferred recognition of the
remaining $5,000,000 of the initial fee, which was allocated to the AZD3480 license grants, until December 2006, when AstraZeneca made a determination to proceed with further development of AZD3480 following the completion of additional clinical and
non-clinical studies that AstraZeneca conducted during 2006. On December 27, 2006, AstraZeneca communicated its decision to proceed with further development of AZD3480 to the Company. As a result, in the first quarter of 2007, the Company began
recognizing the $5,000,000 of the initial fee that it had previously deferred as revenue on a straight-line basis over the estimated five-year development period for AZD3480. In July 2009, the Company announced that it had been informed by
AstraZeneca of AstraZeneca's plans to conduct further development of AZD3480 for ADHD. The Company extended its estimate of the development period for AZD3480 to continue through 2013 and began recognizing the part of the $5,000,000 portion of
the initial fee not yet recognized as of April 1, 2009 as revenue on a straight-line basis over the remaining estimated development period. The Company recognized $145,000 and $457,000 of the initial fee as revenue for three months ended
September 30, 2010 and 2009, respectively, and $538,000 and $1,477,000 of the initial fee as revenue for the nine months ended September 30, 2010 and 2009, respectively.
Under the agreement, the Company is also eligible to receive (1) additional payments of up to $103,000,000 if development, regulatory and first commercial sale milestone events for AZD3480 are
achieved only for ADHD, (2) other payments if development, regulatory, first commercial sale and first detail milestone events for AZD3480 are achieved for any other target indication under the agreement and (3) if regulatory approval is
achieved for AZD3480 for any particular indication, stepped double-digit royalties on any sales of AZD3480 for that indication or any other indication. Under the terms of a sponsored research agreement and a subsequent license agreement between the
Company and University of Kentucky Research Foundation, or UKRF, if the Company receives any of these payments from AstraZeneca related to AZD3480, including royalties, the Company is required to pay a low single digit percentage of each such
payment to UKRF.

5. Strategic Alliance and Collaboration Agreements (continued)
The Company is exploring the practicability of conducting an additional
clinical trial of AZD3480 in Alzheimer's disease. In September 2010, the Company and AstraZeneca amended the agreement to enable the Company potentially to conduct such a trial and to provide for respective roles and responsibilities and
associated financial terms. Under the amendment, AstraZeneca paid the Company $500,000 in October 2010.
With respect to AZD1446, the most
advanced product candidate that arose out of the parties' preclinical research collaboration described below, the Company is also eligible to receive payments of up to $73,000,000, if development, regulatory, first commercial sale and first
detail milestone events for AZD1446 are achieved for a single indication under the agreement, and, if regulatory approval is achieved for AZD1446 for any particular indication, stepped royalties on any sales of AZD1446 for that indication or any
other indication.
The Company would recognize any revenue based on the achievement of any milestone event under the agreement upon
achievement of the milestone event if the Company determines that the revenue satisfies the requirements for immediate recognition under its revenue recognition policy (see Note 2). The Company and AstraZeneca also conducted a multi-year preclinical
research collaboration under the agreement. The term of the research collaboration expired in January 2010. While the research collaboration was ongoing, the Company was eligible to receive payments from AstraZeneca for research services performed.
The Company recognized collaboration research and development revenue as the research was performed and related expenses were incurred. As a result of the expiration of the research collaboration in January 2010, the Company did not recognize any
collaboration research and development revenue for the three or nine months ended September 30, 2010. The Company recognized collaboration research and development revenue of $1,059,000 and $3,724,000 for the three and nine months ended
September 30, 2009, respectively.
In October 2007, the Company provided notice under the agreement offering AstraZeneca the right to
license its product candidate TC-5619 for specified conditions characterized by cognitive impairment. Based on a subsequent election by AstraZeneca made under the terms of the agreement, AstraZeneca paid the Company $2,000,000 and the Company agreed
to develop TC-5619 independently through completion of Phase 1 clinical development and a Phase 2 clinical proof of concept clinical trial in accordance with a mutually acceptable development plan, following which AstraZeneca would have the right to
license TC-5619 on terms specified in the agreement. The Company is recognizing the $2,000,000 payment as revenue on a straight-line basis over the estimated period of the Company's research and development obligations for TC-5619. Accordingly,
the Company recognized $43,000 and $122,000 of the payment as revenue for the three months ended September 30, 2010 and 2009, respectively, and $235,000 and $474,000 of the payment as revenue for the nine months ended September 30, 2010
and 2009, respectively.

5. Strategic Alliance and Collaboration Agreements (continued)
In April 2010, the Company and AstraZeneca amended the agreement to modify
the terms applicable to TC-5619. In conjunction with the amendment, the Company and AstraZeneca agreed to an expanded development program for TC-5619 and the Company received a payment of $11,000,000 to maintain AstraZeneca's future option to
license TC-5619. The Company recorded the $11,000,000 payment as deferred revenue and is recognizing it as revenue on a straight-line basis over the estimated period of the Company's research and development obligations for TC-5619. The Company
recognized $2,357,000 and $3,929,000 of the payment as revenue for the three and nine months ended September 30, 2010, respectively.
As
part of the expanded TC-5619 development program, the Company has two Phase 2 clinical proof of concept trials ongoing, one in cognitive dysfunction in schizophrenia, or CDS, and one in ADHD. The Company also agreed to conduct specified clinical and
non-clinical studies, and AstraZeneca agreed to conduct other specified non-clinical studies, to support the potential advancement of TC-5619 into Phase 2 clinical development for Alzheimer's disease. A decision as to whether to conduct Phase 2
clinical development of TC-5619 for Alzheimer's disease would be made in the future. If TC-5619 has been licensed by AstraZeneca or remains subject to AstraZeneca's license option, any Phase 2 clinical development for Alzheimer's
disease would be funded by AstraZeneca.
Under the agreement, AstraZeneca has an option for an exclusive license to TC-5619 for various
cognitive disorders the first time that TC-5619 achieves clinical proof of concept, whether in CDS, ADHD or Alzheimer's disease. The amended terms also allow AstraZeneca to exercise its option to license TC-5619 upon completion of the other
clinical and non-clinical studies related to Alzheimer's disease if TC-5619 does not achieve clinical proof of concept in CDS or ADHD. If AstraZeneca exercises its option, it would pay the Company an exercise fee of $30,000,000 and assume
responsibility for and fund all future development and commercialization for TC-5619 beyond the currently agreed upon development program. In that event, the Company would be eligible to receive additional payments of up to $212,000,000, if
development, regulatory, first commercial sale and first detail milestone events for TC-5619 are achieved in three indications, and stepped double-digit royalties on any future TC-5619 product sales for any indication. If AstraZeneca does not
exercise its option the first time that TC-5619 achieves clinical proof of concept, whether in CDS, ADHD or Alzheimer's disease, or if TC-5619 achieves clinical proof of concept in neither CDS nor ADHD and AstraZeneca disclaims any further
interest, the Company would retain all of its rights in TC-5619.
The Company has also received payments under the agreement that it
recognized in full as revenue upon achievement of the corresponding milestone event because the event met each of the conditions required for immediate recognition under its revenue recognition policy (see Note 2). In particular, the Company
received a $10,000,000 payment from AstraZeneca in July 2009 based on achievement of the objective in a completed Phase 2 clinical trial of AZD3480 in adults with ADHD, a milestone event under an amendment to the agreement. The Company made a
payment of $350,000 to UKRF in December 2009 as a result of the $10,000,000 payment received from AstraZeneca. The Company has also received cumulative payments from AstraZeneca of $2,400,000 based on the achievement of milestone events related to
the development of product candidates arising under the parties' completed preclinical research collaboration, including AZD1446.

TC-5214
In December 2009, the Company entered into a collaboration and license agreement with AstraZeneca AB for the global development and commercialization of
TC-5214. Under the agreement, AstraZeneca made an upfront payment to the Company of $200,000,000 and the Company is eligible to receive cumulative payments of up to an additional $540,000,000 if specified development, regulatory and first commercial
sale milestone events for TC-5214 are achieved, cumulative payments of up to an additional $500,000,000 if specified sales related milestone events for TC-5214 are achieved and significant stepped double-digit royalties on net sales of TC-5214
worldwide. The Company recorded the upfront payment made by AstraZeneca as deferred revenue and is recognizing the payment as revenue on a straight-line basis over the estimated period of the Company's substantive performance obligations under
the agreement, or approximately 33 months. The Company recognized $18,290,000 and $54,274,000 of the upfront payment as revenue for the three and nine months ended September 30, 2010, respectively. The Company would recognize as revenue the
full amount of each payment received based on the achievement of milestone events under the agreement upon its achievement if the Company determines that the revenue satisfies the requirements for immediate recognition under its revenue recognition
policy (see Note 2).
The Company and AstraZeneca have jointly designed a program for the global development of TC-5214. The initial program
is planned to include development of TC-5214 as an adjunct therapy and as a second-line "switch" monotherapy, in each case in patients with major depressive disorder who do not respond adequately to first-line antidepressant treatment.
AstraZeneca is responsible for 80% and the Company is responsible for 20% of the costs of the initial program, except that AstraZeneca is responsible for 100% of development costs that are required only to obtain or maintain regulatory approval in
countries outside the United States and the European Union. The Company has the right to terminate its obligation to fund its share of the costs of the initial program once it has funded a specified amount. In addition, for each of the Company and
AstraZeneca, costs that were not contemplated at execution to be part of the initial program may in some cases be excluded from the cost-sharing arrangement. If the Company funds the specified amount and terminates its obligation to fund its share
of further costs of the initial program, any future milestones and royalties payable to the Company under this agreement would be reduced by the amount of the Company's unfunded share plus interest at a specified rate, subject to a maximum
reduction that may be applied to any one payment. In addition, if the Company and AstraZeneca mutually agree to develop TC-5214 for any indication other than major depressive disorder or in any formulation other than those contemplated by the
initial program, the same cost-sharing arrangement would apply, except that the Company would have the immediate right to terminate its obligation to fund its share of development costs for the other indication or formulation. If the Company
terminates its obligation to fund its share of these other development costs, any future milestones and royalties payable to the Company under this agreement would be reduced by the amount of the Company's unfunded share plus interest at a
specified rate, subject to a maximum reduction that may be applied to any one payment, but only from and after the occurrence of a specified event to be agreed upon by the parties.

5. Strategic Alliance and Collaboration Agreements (continued)
The Company's portion of the costs of the initial program for the three
and nine months ended September 30, 2010 was $2,888,000 and $4,915,000, respectively. AstraZeneca's allocable portion of the initial program costs paid by the Company for the three and nine months ended September 30, 2010 was $929,000
and $1,812,000, respectively, which is reflected in the Company's financial statements as a reduction to research and development expense.
AstraZeneca is responsible under the agreement for executing and funding the costs of global commercialization of TC-5214. The Company has retained an
option to co-promote TC-5214 to a specified target physician audience in the United States. If the Company exercises its co-promotion option, AstraZeneca would compensate the Company on a per detail basis. AstraZeneca is also responsible under the
agreement for the manufacture and supply of TC-5214.
Under the terms of an existing license agreement, the Company paid $16,000,000 to
University of South Florida Research Foundation, or USFRF, in February 2010 based on the Company's receipt of the upfront payment from AstraZeneca and would be required to pay to USFRF a percentage of each milestone payment that may be received
from AstraZeneca, after deducting from the milestone payment the remaining portion of the Company's projected share of the costs of the initial development program for TC-5214, as well as royalties on any future product sales. The percentage of
each milestone payment, net of any deduction, that the Company would be required to pay would be at least 10% and could be greater in specified circumstances. Based on the terms of the license agreement with USFRF and the terms of another existing
license agreement with Yale University, the Company expects to pay royalties at an effective worldwide rate in the low single digits and that the effective royalty rate could in some circumstances reach the mid single digits.
GlaxoSmithKline
On July 27, 2007, the Company entered into a product development and commercialization agreement with SmithKline Beecham Corporation, doing business
as GlaxoSmithKline, and Glaxo Group Limited, which are referred to together as GlaxoSmithKline, that sets forth the terms of an alliance designed to discover, develop and market product candidates that selectively target specified NNR subtypes in
five therapeutic focus areas: pain, smoking cessation, addiction, obesity and Parkinson's disease. In February 2010, GlaxoSmithKline announced plans to cease discovery research in selected neuroscience areas, specifically including pain.
Discussions between the Company and GlaxoSmithKline regarding the effects of its strategic change on the alliance remain ongoing. Until these discussions are completed, the overall impact is uncertain, but the Company anticipates that at least
several of the therapeutic focus areas in the alliance will be discontinued. Because the overall impact has not yet been determined, the remainder of this discussion describes the current terms of the alliance.

NOTES TO UNAUDITED FINANCIAL STATEMENTS (continued)
September 30, 2010
5. Strategic Alliance and Collaboration Agreements (continued)
With respect to each therapeutic focus area in the alliance, if the Company
achieves clinical proof of concept with respect to a lead product candidate, GlaxoSmithKline would have an exclusive option for an exclusive license to that lead product candidate and up to two other product candidates in development in the alliance
for the same therapeutic focus area on a worldwide basis. If GlaxoSmithKline exercises its option and pays the applicable exercise fee, GlaxoSmithKline would become responsible for using diligent efforts to conduct later-stage development and
commercialization of the lead product candidate at its sole expense. GlaxoSmithKline's exclusive license would include all fields of use other than those indications for which the Company has granted development and commercialization rights for
product candidates under its collaboration agreement with AstraZeneca focused in cognitive disorders.
Under the agreement and a related stock
purchase agreement, GlaxoSmithKline made an initial payment to the Company of $20,000,000 and purchased 1,275,502 shares of the Company's common stock for an aggregate purchase price of $15,000,000 on July 27, 2007. The purchase price paid
by GlaxoSmithKline reflected an aggregate deemed premium of $3,521,000, based on the closing price of the Company's common stock on the trading day immediately preceding the date that agreements were signed and announced. The Company deferred
recognition of both the initial payment made by GlaxoSmithKline and the deemed premium paid for the shares of the Company's common stock purchased by GlaxoSmithKline and is recognizing both amounts into revenue on a straight-line basis over the
estimated nine-year period of the Company's research and early development obligations under the agreement. The Company recognized $653,000 of the initial payment and deemed premium as revenue for each of the three-month periods ended
September 30, 2010 and 2009 and $1,960,000 of the initial payment and deemed premium as revenue for each of the nine-month periods ended September 30, 2010 and 2009.
The terms of the alliance provide for the Company to conduct its research and development activities under the agreement at its sole expense. The Company is, however, eligible to receive additional
payments from GlaxoSmithKline, contingent upon the achievement of specified discovery, development, regulatory and commercial milestones as well as stepped double-digit royalties dependent on any future sales for any product licensed by
GlaxoSmithKline. The Company would recognize any revenue based on the achievement of milestones under the agreement upon achievement of the milestone event if the Company determines that the revenue satisfies the requirements for immediate
recognition under its revenue recognition policy (see Note 2). The amounts that the Company may receive depend on the success of the Company's research and development activities, the timing and achievement of the discovery, development,
regulatory and commercial milestone events, the extent to which the specified therapeutic focus areas remain subject to the alliance and whether GlaxoSmithKline exercises any options that are triggered under the agreement.

5. Strategic Alliance and Collaboration Agreements (continued)
In December 2007, the Company received a $6,000,000 payment from GlaxoSmithKline upon the achievement of a specified milestone event under the agreement. The Company determined the payment did not meet
each of the conditions of its revenue recognition policy (see Note 2) required for recognition of the full amount into revenue upon achievement of the milestone. Specifically, based on the progress of this product candidate as of inception of the
agreement, achievement of this milestone was reasonably assured within the meaning of the Company's revenue recognition policy. Accordingly, the Company recorded the payment as deferred revenue and is recognizing it into revenue on a
straight-line basis over the estimated period of the Company's research and early development obligations under the agreement. The Company recognized $173,000 of the payment as revenue for each of the three-month periods ended
September 30, 2010 and 2009 and $519,000 of the payment as revenue for each of the nine-month periods ended September 30, 2010 and 2009.
Beyond the $6,000,000 payment discussed above, the Company has received an aggregate of $4,000,000 in payments from GlaxoSmithKline for achievement of various milestone events under the agreement related
to progress in the Company's preclinical programs, including $2,500,000 for the nine months ended September 30, 2009. The Company immediately recognized the full amount of each payment as revenue upon achievement of the corresponding
milestone event because each event met each of the conditions required for immediate recognition under its revenue recognition policy (see Note 2).
6. Subsequent Events
In November 2010, the Internal Revenue Service notified the Company
that it had approved cumulative grants of $1,467,000 to the Company under the Qualifying Therapeutic Discovery Project tax credit program enacted as part of the Patient Protection and Affordable Care Act of 2010. Approximately $1,431,000 of the
grants reflects qualifying investments made by the Company during 2009 and are to be paid to the Company in November 2010. The remaining $36,000 of the grants reflects qualifying investments made by the Company during 2010 and is to be paid to
the Company in 2011.

Overview
Background
We are a biopharmaceutical company engaged in the design,
discovery and development of novel NNR Therapeutics for the treatment of diseases and disorders of the nervous system. Our NNR Therapeutics selectively target a class of receptors known as neuronal nicotinic receptors, which we refer to as NNRs.
NNRs are found on nerve cells throughout the nervous system and serve as key regulators of nervous system activity.
We have
multiple clinical-stage product candidates and preclinical programs in areas where we believe there are significant medical need and commercial potential, as well as proprietary drug discovery technologies. We have two collaboration agreements with
AstraZeneca, one that we entered into in December 2009 for the global development and commercialization of TC-5214 as a treatment for major depressive disorder, or MDD, and refer to in this quarterly report as our "TC-5214 agreement with
AstraZeneca" and the other focused in cognitive disorders that we entered into in December 2005 and refer to in this quarterly report as our "cognitive disorders agreement with AstraZeneca." We also have an alliance agreement with
GlaxoSmithKline. Our most advanced product candidates are described below:
•
TC-5214
. TC-5214 is a nicotinic channel blocker that is thought to derive antidepressant activity by modulating the activity of various NNR
subtypes. We are co-developing TC-5214 with AstraZeneca under our TC-5214 agreement with AstraZeneca as an adjunct (or add-on) therapy for patients with MDD who do not respond adequately to first-line antidepressant treatment. Phase 3 clinical
trials of TC-5214 are ongoing. In addition, we expect a Phase 2 clinical trial of TC-5214 as a second-line "switch" monotherapy to initiate in the first quarter of 2011.
•
TC-5619
. TC-5619 is a novel small molecule that modulates the activity of the
a
7 NNR. We have two
Phase 2 clinical trials of TC-5619 ongoing, one in cognitive dysfunction in schizophrenia, or CDS, and one in adults with attention deficit/hyperactivity disorder, or ADHD. We are also conducting clinical and non-clinical studies to support the
potential
21
Table of Contents
advancement of TC-5619 into Phase 2 clinical development in Alzheimer's disease. A decision as to whether to conduct Phase 2 clinical development of TC-5619 as a treatment for
Alzheimer's disease would be made in the future. AstraZeneca has an option for an exclusive license to TC-5619 for various cognitive disorders that is exercisable the first time that TC-5619 achieves Phase 2 clinical proof of concept, whether
in CDS, ADHD or Alzheimer's disease. AstraZeneca also can exercise its license option upon completion of specified clinical and non-clinical studies related to Alzheimer's disease if TC-5619 does not achieve clinical proof of concept
in CDS or ADHD.
•
AZD3480 (TC-1734)
. AZD3480 is a novel small molecule that modulates the activity of the
a
4ß2 NNR and is subject to our cognitive disorders agreement with AstraZeneca. We or AstraZeneca have conducted several clinical studies of AZD3480 in various cognitive disorders and we are in
discussions with AstraZeneca regarding potential additional development as a treatment for ADHD. Whether AstraZeneca will decide to conduct any additional development of AZD3480 in ADHD is uncertain in light of reservations about the adequacy
of the therapeutic margin to support development across the broad ADHD patient population. We expect AstraZeneca to make its decision by the end of 2010.
•
AZD1446 (TC-6683).
AZD1446 is a novel small molecule that modulates the activity of the
a
4ß2
NNR and is under consideration for further development as a treatment for Alzheimer's disease under our cognitive disorders agreement with AstraZeneca. We discovered AZD1446 as part of a multi-year preclinical research collaboration conducted
under the agreement. AstraZeneca has completed three of four Phase 1/2a clinical studies expected to inform its decision whether to advance AZD1446, and we expect AstraZeneca's decision in the coming months.
•
TC-6987
. TC-6987 is a novel small molecule that modulates the activity of the
a
7 NNR and is in
development as a treatment for inflammatory disorders. We have completed a Phase 1 single rising dose clinical trial and a Phase 1 multiple rising dose clinical trial of TC-6987. We plan to conduct multiple Phase 2 learning trials to identify the
optimal indication for TC-6987, with the first such study to be in asthma and expected to initiate in 2010.
•
TC-6499
. TC-6499 is a product candidate that we previously evaluated and are no longer developing as a pain treatment. Based on the activity of
TC-6499 at certain NNR subtypes located in the gastrointestinal tract, we believe it may have potential as a treatment for certain gastrointestinal disorders. We are conducting an ongoing exploratory Phase 2a study of TC-6499 as a treatment for
constipation-predominant irritable bowel syndrome.
Under our TC-5214 agreement with AstraZeneca, we and
AstraZeneca have jointly designed an initial development program that is planned to include development of TC-5214 as an adjunct therapy and as a second-line "switch" monotherapy, in each case in patients with MDD who do not respond
adequately to first-line antidepressant treatment. AstraZeneca is responsible for 80% and we are responsible for 20% of the costs of the initial program, except that AstraZeneca is responsible for 100% of development costs that are required only to
obtain or maintain regulatory approval in countries outside the United States and the European Union. We have the right to terminate our obligation to fund our share of the costs of the initial program once we have funded a specified amount. In
addition, for each of us and AstraZeneca, costs that were not contemplated at execution to be part of the initial program may in some cases be excluded from the cost-sharing arrangement.
22
Table of Contents
If we fund the specified amount and terminate our obligation to fund our share of further costs of the initial program, any future milestones and royalties payable to us under the agreement would
be reduced by the amount of our unfunded share plus interest at a specified rate, subject to a maximum reduction that may be applied to any one payment. AstraZeneca is responsible for executing and funding the costs of global commercialization of
TC-5214.
Under our cognitive disorders agreement with AstraZeneca:
•
we are responsible for conducting and funding the ongoing Phase 2 clinical trials of TC-5619 in CDS and in adults with ADHD, as well as specified
clinical and non-clinical studies to support the potential advancement of TC-5619 into Phase 2 clinical development for Alzheimer's disease; AstraZeneca is responsible for conducting and funding other specified non-clinical studies to support
the potential advancement of TC-5619 into Phase 2 clinical development for Alzheimer's disease;
•
except as discussed in the next bullet, AstraZeneca is responsible for substantially all current and future development costs for AZD3480, AZD1446 and
each other compound arising from the preclinical research collaboration described below that it elects to advance;
•
we are exploring the practicability of conducting an additional clinical trial of AZD3480 in Alzheimer's disease and have agreed with AstraZeneca
on respective roles and responsibilities for such a study; if an Alzheimer's disease study proceeds, we would be responsible for funding the study but would be entitled to receive approximately $6.2 million from AstraZeneca, in tranches
culminating with dosing; and
•
from January 2006 to January 2010, we and AstraZeneca conducted a preclinical research collaboration under the agreement to discover and develop
compounds that act on the
a
4ß2 NNR as treatments for conditions characterized by cognitive impairment; AstraZeneca paid us research fees, based on a reimbursement rate specified under the agreement,
for research services rendered in the preclinical research collaboration.
In addition to our two
collaboration agreements with AstraZeneca, we have an alliance agreement with GlaxoSmithKline that is designed to discover, develop and market product candidates that selectively target specified NNR subtypes in specified therapeutic focus areas. In
February 2010, GlaxoSmithKline announced plans to cease discovery research in selected neuroscience areas. Although the overall impact of GlaxoSmithKline's strategic change on our alliance has not yet been finally determined, we anticipate that
at least several therapeutic focus areas in the alliance will be discontinued.
We trace our scientific lineage to a research
program initiated by R.J. Reynolds Tobacco Company in 1982 to study the activity and effects of nicotine in the body. We were incorporated in 1997 as a wholly owned subsidiary of RJR. In August 2000, we became an independent company when we issued
and sold stock to venture capital investors. Since our inception, we have had limited revenue from product sales and have funded our operations principally through the sale of equity securities, revenue from collaboration agreements, grants and
equipment and building lease incentive financing. We have devoted substantially all of our resources to the discovery and development of our product candidates and technologies, including the design, conduct and management of preclinical and
clinical studies and related manufacturing, regulatory and clinical affairs, as well as intellectual property prosecution.

Table of Contents
We generated net
income for the three and nine months ended September 30, 2010 due primarily to recognition into revenue of a portion of the upfront payment received under our TC-5214 agreement with AstraZeneca. We have also generated net income for two other
quarterly periods since our inception, in each case due primarily to the achievement in each period of a single milestone event related to AZD3480 under our cognitive disorders agreement with AstraZeneca. Except for these periods, we have not been
profitable and we may incur losses in future periods as our clinical-stage and preclinical product candidates advance into later-stage development and as we progress our programs, invest in additional product opportunities and expand our research
and development infrastructure. As of September 30, 2010, we had an accumulated deficit of $216.2 million. Clinical trials and preclinical studies are time-consuming, expensive and may never yield a product that will generate revenue.
As a clinical-stage company, our revenues, expenses and results of operations are likely to fluctuate significantly from
quarter to quarter and year to year. We believe that period-to-period comparisons of our results of operations should not be relied upon as indicative of our future performance.
Revenue
In January 2010, we received a $200.0 million upfront payment under our TC-5214 agreement with AstraZeneca, which we recorded as deferred
revenue and are recognizing into revenue on a straight-line basis over the estimated development period for TC-5214 to submission of a new drug application to the U.S. Food and Drug Administration, or FDA. We are eligible under our TC-5214 agreement
with AstraZeneca to receive additional payments of over $1.0 billion if development, regulatory, first commercial sale and specified sales related milestone events for TC-5214 are achieved and stepped double-digit royalties on any future TC-5214
product sales. As of September 30, 2010, we had $145.3 million of the deferred portion of the upfront payment remaining to be recognized into revenue. Pursuant to the April 2010 amendment to our cognitive disorders agreement with AstraZeneca,
we received an $11.0 million payment in May 2010, which we recorded as deferred revenue and are recognizing into revenue on a straight-line basis over the estimated period of our research and development obligations related to TC-5619.
As of September 30, 2010 we had received $55.4 million in aggregate upfront fees and milestone payments under our cognitive
disorders agreement with AstraZeneca and recognized an additional $26.5 million in collaboration research and development revenue for research services that we provided under the agreement. As of September 30, 2010, we had also received $45.0
million in aggregate payments under our alliance agreement with GlaxoSmithKline. We initially deferred recognition of an aggregate of $52.5 million received under our cognitive disorders agreement with AstraZeneca and from GlaxoSmithKline and are
recognizing these deferred amounts into revenue over the periods discussed in Note 5 to our unaudited financial statements included in this quarterly report. As of September 30, 2010, we had $28.8 million of the deferred amounts remaining to be
recognized in future periods. In October 2010, we received an additional $500,000 from AstraZeneca in connection with an amendment to our cognitive disorders agreement with AstraZeneca.

We acquired rights to
Inversine, which is our only product approved for marketing by the FDA, in August 2002. Effective September 30, 2009, we discontinued Inversine. Sales of Inversine generated net revenue of $118,000 and $473,000 for the three and nine months
ended September 30, 2009, respectively.
From time to time we seek and are awarded grants or work to be performed under
grants awarded to third-party collaborators from which we derive revenue. As of September 30, 2010, we have been awarded two grants from The Michael J. Fox Foundation for Parkinson's Research, or MJFF. One of the grants is to fund
preclinical research involving the use of compounds that modulate NNRs to address Levodopa-induced abnormal involuntary movements, known as dyskinesias, and we have received aggregate payments of $641,000 from MJFF since August 2009 in connection
with this grant. The other grant is to fund research to identify NNR-related biomarkers relevant to Parkinson's disease, and we expect to receive an aggregate of $304,000 from MJFF over a one-year period that began in December 2009 in
connection with this grant. In addition, as of September 30, 2010, we are a named subcontractor under a grant awarded to The California Institute of Technology by the National Institute on Drug Abuse, or NIDA, part of the National Institutes of
Health, to fund research on innovative NNR-based approaches to the development of therapies for smoking cessation. We have received approximately $1.1 million in the aggregate over a five-year research term that began in July 2006 in connection with
the NIDA grant. Funding for awards under federal grant programs is subject to the availability of funds as determined annually in the federal appropriations process.
Research and Development Expenses
Since our inception, we have focused our
activities on our drug discovery and development programs. We record research and development expenses as they are incurred. Research and development expenses represented approximately 89% and 81% of our total operating expenses for the three months
ended September 30, 2010 and 2009, respectively, and 88% and 84% of our total operating expenses for the nine months ended September 30, 2010 and 2009, respectively.
We utilize our research and development personnel and infrastructure resources across several programs. We currently have clinical, preclinical and early research programs, and many of our costs are not
specifically attributable to a single program. Instead, these costs are directed to broadly applicable research efforts. Accordingly, we cannot state precisely our total costs incurred on a program-by-program basis.
We have not received FDA or foreign regulatory marketing approval for any of our product candidates that are in development. Our current
and future expenditures on preclinical and clinical development programs are subject to numerous uncertainties in timing and cost to completion. In particular, our strategy includes entering into alliances and collaborations with third parties to
participate in the development and commercialization of some of our product candidates. Where a third party has responsibility for or authority over any or all of the preclinical or clinical development of a particular product candidate, the
estimated completion date may be largely under the control of that third party and not under our control. We cannot forecast with certainty whether AstraZeneca will exercise any options to license particular product candidates that become
exercisable under the terms of our cognitive disorders agreement with AstraZeneca, whether GlaxoSmithKline will exercise any options to license particular product candidates that become exercisable under the terms of our alliance agreement with
GlaxoSmithKline, whether any of our product candidates will be subject to future alliances or collaborations or how any such arrangement would affect our
25
Table of Contents
development plans or capital requirements. Because of this uncertainty, and because of the numerous uncertainties related to clinical trials and drug development generally, we are unable to
determine the duration and completion costs of our research and development programs or whether or when we will generate revenue from the commercialization and sale of any of our product candidates in development.
General and Administrative Expenses
General and administrative expenses consist principally of salaries and other related costs for personnel in executive, finance, business development, legal and human resource functions. Other general and
administrative expenses include expenses associated with stock options granted to personnel in those functions, depreciation and other facility costs not otherwise included in research and development expenses, patent-related costs, insurance costs
and professional fees for consulting, legal, accounting and public and investor relations services.
Income Taxes
We have incurred net operating losses through December 31, 2009 and have not paid federal, state or foreign income
taxes for any period through December 31, 2009. We expect that we may incur taxable income, before giving effect to net operating loss carryforwards, for the year ending December 31, 2010. For the three and nine months ended
September 30, 2010, we recognized $257,000 and $2.4 million, respectively, of income tax expense primarily as a result of the application of Accounting Standards Codification Topic 740,
Income Taxes,
or ASC 740, to stock-based
compensation. Exercises of stock options during the three and nine months ended September 30, 2010 resulted in tax deductions for stock-based compensation in excess of expense recorded for the stock options under U.S. generally accepted
accounting principles, or GAAP, resulting in income tax benefits of $160,000 and $2.3 million, respectively. We recognized the income tax benefit related to the excess tax deductions as an increase to capital in excess of par value, which based on
ASC 740 resulted in an offsetting charge in the same amount to income tax expense. As of September 30, 2010, we had net operating loss carryforwards of $66.0 million for federal income tax purposes and $76.8 million for state income tax
purposes. We also had research and development income tax credit carryforwards of $7.4 million for federal income tax purposes and $595,000 for state income tax purposes as of September 30, 2010. The federal net operating loss carryforwards
begin to expire in 2020. The state net operating loss carryforwards begin to expire in 2015. The federal and state research and development tax credits begin to expire in 2021. As a result of various factors, including the subjectivity of
measurements used in the calculation of particular tax positions taken or that may in the future be taken in our tax returns, it is uncertain whether or to what extent we will be eligible to use the tax credits.
Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to ownership change
limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. When an ownership change, as defined by Section 382, occurs, an annual limitation is imposed on a company's use of net
operating loss and credit carryforwards attributable to periods before the change. As a result of a series of stock issuances, we had such an ownership change in November 2002. Consequently, an annual limitation is imposed on our use of net
operating loss and credit carryforwards that are attributable to periods before November 2002. In addition, a portion of the net operating loss carryforwards described above may potentially not be usable by us if we experience further ownership
changes in the future. For financial reporting purposes, we have recorded a valuation allowance to fully offset the deferred tax asset related to these carryforwards and the tax credits because the likelihood that we will be eligible to use or
realize any benefit from them is uncertain.

Fair Value
The carrying amounts of our cash and cash equivalents, investments in marketable securities, accounts receivable, accounts
payable and accrued expenses are considered to be representative of their respective fair values due to their short-term nature and, in the case of short-term investments, their market interest rates. Likewise, the carrying amounts of our long-term
debts are considered to be representative of their fair value due to their market interest rates. Cash that we do not expect to need to fund our short-term liquidity requirements is invested in U.S. Treasury notes and bonds, U.S. federal and state
agency-backed certificates and corporate debt securities that are rated at least A quality or equivalent. Our investments in marketable securities of $98.2 million at September 30, 2010, which include marketable securities classified on our
balance sheet as cash equivalents, are recorded at fair value using quoted market prices.
Critical Accounting Policies
and Estimates
Our management's discussion and analysis of our financial condition and results of operations are
based on our unaudited financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information. The preparation of these financial statements requires us to make estimates and
judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate these estimates and judgments. We base our estimates on historical experience and on various assumptions that we believe to be
reasonable under the circumstances. These estimates and assumptions form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenues and expenses that are not readily apparent from other sources.
Actual results and experiences may differ materially from these estimates. In addition, our reported financial condition and results of operations could vary if new accounting standards are enacted that are applicable to our business.
Our significant accounting policies are described in Note 2 to our audited financial statements included in our Annual Report on Form
10-K for the year ended December 31, 2009 and in the notes to our financial statements included in this quarterly report. We believe that our accounting policies relating to revenue recognition, accrued expenses and stock-based compensation are
the most critical to understanding and evaluating our reported financial results. We have identified these policies as critical because they are important to the presentation of our financial condition and results of operations and require us to
make judgments and estimates on matters that are inherently uncertain and may change in future periods. These policies are described under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations
– Critical Accounting Policies and Estimates" in our Annual Report on Form 10-K for the year ended December 31, 2009.

Net operating revenues for the three months ended September 30, 2010 increased by $9.1 million as
compared to the three months ended September 30, 2009. The higher net operating revenues were primarily attributable to an increase of $10.3 million in milestones and license fees from collaborations revenue, partially offset by a decrease of
$1.1 million in collaboration research and development revenue. The increase in milestones and license fees from collaborations revenue reflected recognition of $18.3 million of the $200.0 million upfront payment received under our TC-5214 agreement
with AstraZeneca, which we entered into in December 2009, and $2.4 million of the $11.0 million payment received under an April 2010 amendment to our cognitive disorders agreement with AstraZeneca to modify the terms applicable to TC-5619, partially
offset by achievement of a milestone event under our cognitive disorders agreement with AstraZeneca during the three months ended September 30, 2009 for which we received $10.0 million and a decrease for the 2010 period of $313,000 of license
fees derived from the cognitive disorders agreement as a result of the expiration of the term of the preclinical research collaboration in January 2010. The decrease in collaboration research and development revenue for the 2010 period resulted from
the completion of the preclinical research collaboration under our cognitive disorders agreement with AstraZeneca. We plan to recognize the remaining $145.3 million of the upfront payment received under the TC-5214 agreement with AstraZeneca on a
straight-line basis over the estimated development period for TC-5214 to submission of a new drug application to the FDA and, as a result, expect to have higher net operating revenues for the year ending December 31, 2010 as compared to the
year ended December 31, 2009. As of September 30, 2010, we forecast the new drug application submission date for TC-5214 to be approximately September 30, 2012. We do not expect to record any collaboration research and development
revenue from the cognitive disorders agreement for the year ending December 31, 2010 or any future period.

Research and
development expenses for the three months ended September 30, 2010 increased by $8.1 million as compared to the three months ended September 30, 2009. The higher research and development expenses were principally attributable to:
•
an increase of $5.2 million in costs incurred for third-party research and development services in connection with our clinical-stage product
candidates (including costs for clinical trial activities, formulation activities, production of clinical trial materials, and pharmacology, toxicology and other non-clinical studies) to $7.0 million for the 2010 period from $1.8 million for the
2009 period; this increase was principally due to the conduct of Phase 2 clinical development of TC-5619 for two indications, the conduct of later-stage Phase 1 clinical development of TC-6987 and our cost-sharing obligations with respect to ongoing
Phase 3 clinical trials of TC-5214;
•
a $1.5 million upfront payment that we made to Cornerstone Therapeutics Inc. upon entering into an exclusive worldwide license agreement in August
2010;
•
an increase of $814,000 in stock-based compensation, salary and other compensation-related expenses for research and development personnel to $4.4
million for the 2010 period from $3.6 million for the 2009 period; the largest component of this increase was stock-based compensation expense and was primarily due to a significantly higher fair value calculated for stock options granted during
2010 as compared to the fair value calculated for stock options granted during and prior to 2009; and
•
an increase of $633,000 in other research and development expenses, including infrastructure costs, to $3.1 million for the 2010 period from $2.5
million for the 2009 period; this increase was primarily due to increases in the number of employees and depreciable equipment utilized in our research and development functions.
These increases were partially offset by a decrease of $141,000 in costs incurred for third-party research and development services in connection with
our preclinical programs to $1.3 million for the 2010 period from $1.4 million for the 2009 period. The reduced spending for the 2010 period in connection with our preclinical programs primarily resulted from the uncertainty surrounding the
continuation of some of the therapeutic focus areas of our alliance with GlaxoSmithKline.
The costs that we incurred for the
three months ended September 30, 2010 and 2009 for third-party services in connection with research and development of clinical-stage product candidates are shown in the table below:

of $407,000 in stock-based compensation, salary and other compensation-related expenses for general and administrative personnel to $1.2 million for the 2010 period from $776,000 for the 2009 period. The largest component of the increase was
stock-based compensation expense and was primarily due to a significantly higher fair value calculated for stock options granted during 2010 as compared to the fair value calculated for stock options granted during and prior to the 2009 period.

Net operating revenues for the nine months ended September 30, 2010 increased by $40.6 million as
compared to the nine months ended September 30, 2009. The higher net operating revenues were primarily attributable to an increase of $44.3 million in milestones and license fees from collaborations revenue, partially offset by a decrease of
$3.7 million in collaboration research and development revenue. The increase in milestones and license fees from collaborations revenue reflected recognition of $54.3 million of the $200.0 million upfront payment received under our TC-5214 agreement
with AstraZeneca and $3.9 million of the $11.0 million payment received under the April 2010 amendment to our cognitive disorders agreement with AstraZeneca, partially offset by the achievement of a milestone event under our cognitive disorders
agreement with AstraZeneca during the nine months ended September 30, 2009 for which we received $10.0 million and decreases for the 2010 period of $2.5 million in aggregate payments received from GlaxoSmithKline upon achievement of milestone
events under our alliance agreement and $833,000 in license fees derived from the cognitive disorders agreement as a result of the expiration of the term of the preclinical research collaboration in January 2010. The decrease in collaboration
research and development revenue for the 2010 period resulted from the completion of the preclinical research collaboration under the cognitive disorders agreement with AstraZeneca.

development expenses for the nine months ended September 30, 2010 increased by $12.2 million as compared to the nine months ended September 30, 2009. The higher research and development expenses were principally attributable to:
•
an increase of $7.9 million in costs incurred for third-party research and development services in connection with our clinical-stage product
candidates to $15.6 million for the 2010 period from $7.7 million for the 2009 period; this increase was principally due to the conduct of Phase 2 clinical development of TC-5619 for two indications, the conduct of multiple Phase 1 clinical trials
of TC-6987 and our cost-sharing obligations with respect to ongoing Phase 3 clinical trials of TC-5214;
•
an increase of $2.5 million in stock-based compensation, salary and other compensation-related expenses for research and development personnel to $13.6
million for the 2010 period from $11.1 million for the 2009 period; the largest component of this increase was stock-based compensation expense and was primarily due to a significantly higher fair value calculated for stock options granted during
2010 as compared to the fair value calculated for stock options granted during and prior to 2009;
•
an increase of $1.7 million in other research and development expenses, including infrastructure costs, to $9.1 million for the 2010 period from $7.4
million for the 2009 period; this increase was primarily due to increases in the number of employees and depreciable equipment utilized in our research and development functions; and
•
the $1.5 million upfront payment that we made to Cornerstone Therapeutics Inc.
These increases were partially offset by a decrease of $1.4 million in costs incurred for third-party research and development services in connection
with our preclinical programs to $2.2 million for the 2010 period from $3.6 million for the 2009 period. The reduced spending for the 2010 period in connection with our preclinical programs primarily resulted from the uncertainty surrounding the
continuation of some of the therapeutic focus areas of our alliance with GlaxoSmithKline.
The costs that we incurred for the
nine months ended September 30, 2010 and 2009 for third-party research and development services in connection with clinical-stage product candidates are shown in the table below:

General and
administrative expenses for the nine months ended September 30, 2010 increased by $1.2 million as compared to the nine months ended September 30, 2009. The higher general and administrative expenses were primarily attributable to an
increase of $984,000 in stock-based compensation, salary and other compensation-related expenses for general and administrative personnel to $3.4 million for the 2010 period from $2.5 million for the 2009 period. The largest component of the
increase was stock-based compensation expense and was primarily due to a significantly higher fair value calculated for stock options granted during 2010 as compared to the fair value calculated for stock options granted during and prior to 2009.

Interest income for the

Treasury notes and bonds, U.S. federal and state agency-backed certificates and corporate debt securities, partially offset by lower interest rates. Interest expense for the nine months ended September 30, 2010 decreased by $56,000 as compared
to the nine months ended September 30, 2009.

Income tax expense for the
nine months ended September 30, 2010 was $2.4 million as compared to an income tax benefit of $83,000 for the nine months ended September 30, 2009, a change of $2.5 million. The change was primarily due to tax deductions for stock-based
compensation for the 2010 period in excess of expense recorded under GAAP for the corresponding stock options. Tax deductions in excess of recorded expense are only recognized for periods with net income.
Liquidity and Capital Resources
Sources of Liquidity
We have historically financed our operations and
internal growth primarily through public and private offerings of our securities, payments under collaborations and alliances, including upfront fees, payments for research and development services and payments upon achievement of milestone events,
equipment and building lease incentive financing, government grants and interest income. We discontinued our only approved product, Inversine, effective as of September 30, 2009. The net contribution from Inversine sales was not historically a
significant source of cash.
In December 2009, we entered into a collaboration and license agreement with AstraZeneca for the
global development and commercialization of TC-5214. We received a $200.0 million upfront payment from AstraZeneca in January 2010. Under the terms of an existing license agreement, we paid $16.0 million to University of South Florida Research
Foundation, or USFRF, in January 2010 based on our receipt of the upfront payment from AstraZeneca.
As discussed above under
the caption "—Overview— Revenue," we are eligible to receive substantial additional payments from AstraZeneca, contingent on the achievement of specified milestone events related to TC-5214, AZD3480, AZD1446, and, if AstraZeneca
licenses TC-5619, TC-5619 and from GlaxoSmithKline, contingent on the achievement of specified milestone events in the specified therapeutic focus areas of the alliance. There is no assurance that we will achieve any particular milestone event in
2010, in any future period or at all. In particular, in February 2010, GlaxoSmithKline announced plans to cease discovery research in selected neuroscience areas. Although the overall impact of GlaxoSmithKline's strategic change on our alliance
has not yet been finally determined, we anticipate that at least several therapeutic focus areas in the alliance will be discontinued. In that event, we would no longer be eligible to receive milestone payments from GlaxoSmithKline for those
therapeutic focus areas, which would diminish the alliance as a potential source of future funds.
In July 2010, we entered
into a loan agreement with a bank that provides aggregate borrowing capacity of $4.0 million to be provided in up to three individual term loans that we may take at any time on or prior to June 30, 2011 to fund the purchase of equipment,
furnishings, software
34
Table of Contents
and other fixed assets. In September 2010, we borrowed $1.2 million under this loan facility at a fixed interest rate of 3.4% per annum. We are obligated only to pay interest through the
remainder of 2010. Beginning January 1, 2011 and continuing through the maturity date of December 1, 2014, the loan is repayable in equal monthly installments of $28,000. We granted to the bank a first priority security interest in the
assets acquired with the proceeds of the loan. Any future loan under the facility would, at our discretion on a loan-by-loan basis, bear interest at either a variable rate equal to the thirty-day LIBOR plus 2.15%, adjusted monthly on the first day
of each month, or a fixed rate equal to the bank's fixed rate cost of funds index corresponding to the term of the loan plus 2.15%. Any additional loan that we take during 2010 would be interest only through 2010 and then would be re-payable in
equal monthly installments of principal and interest over 48 months. Any loan that we take during the first half of 2011 would be interest only through June 30, 2011 and then would be re-payable in equal monthly installments of principal and
interest over the next 48 months.
In March 2008, we entered into a loan agreement with a bank that provided borrowing
capacity of $5.3 million to fund the purchase of equipment, furnishings, software and other fixed assets and enable the refinancing of our then-existing loan facility with R.J. Reynolds Tobacco Holdings, Inc. We borrowed $4.8 million upon
entering into the loan agreement and borrowed the remaining $489,000 in September 2008. Pursuant to the loan agreement, we granted a first priority security interest in favor of the bank in the assets acquired with the proceeds of the loan facility
or the previous facility that it replaced. The March 2008 loan bears interest at a fixed rate of 5.231% per annum and is repayable in equal monthly installments of $112,000 beginning April 1, 2008 and continuing through the maturity date
of March 1, 2012. The September 2008 loan bears interest at a fixed rate of 6.131% per annum and is repayable in equal monthly installments of $11,000 beginning October 1, 2008 and continuing through the maturity date of
September 1, 2012. As of September 30, 2010, the outstanding principal balance under the loan facility was $2.2 million. There is no additional borrowing capacity remaining available to us under the loan agreement.
In April 2002, we received a $500,000 loan from the City of Winston-Salem. Under the terms of the loan, there was no interest accrual or
payment due until the fifth anniversary of the loan. Following expiration of the five-year grace period in April 2007, the outstanding principal balance of the loan began to bear interest at an annual interest rate of 5% and became payable in 60
equal monthly installments of $9,000. As of September 30, 2010, the outstanding principal balance under the loan was $161,000.
Our cash, cash equivalents and investments in marketable securities were $268.0 million as of September 30, 2010 and $111.1 million as of December 31, 2009. As of September 30, 2010, the
majority of our cash, cash equivalents and investments were invested in bank depository accounts and institutional money market funds at Branch Banking and Trust Company, RBC Bank and Wells Fargo & Company. In addition, as of
September 30, 2010, we had cash of $98.2 million that we do not expect to need to fund our short-term liquidity requirements invested in U.S. Treasury notes and bonds, U.S. federal and state agency-backed certificates, corporate debt securities
that are rated at least A quality or equivalent and certificates of deposit.

Net cash provided by operating activities for the nine months ended September 30, 2010 was
$154.0 million and net cash used in operating activities for the nine months ended September 30, 2009 was $12.5 million, a difference of $166.6 million.
For the nine months ended September 30, 2010, net cash provided by operating activities was principally the result of our receipt of:
•
the $200.0 million upfront payment under our TC-5214 agreement with AstraZeneca in January 2010;
•
the $11.0 million payment under an amendment to our cognitive disorders agreement with AstraZeneca to modify the terms applicable to TC-5619 in April
2010; and
•
$397,000 under our grants with MJFF.
These cash inflows were partially offset by:
•
our payments in January 2010 of $16.0 million to USFRF based on our receipt of the $200.0 million upfront payment under our TC-5214 agreement with
AstraZeneca and $350,000 to University of Kentucky Research Foundation as a result of the $10.0 million milestone payment we received from AstraZeneca in July 2009 for achievement of a milestone event under our cognitive disorders agreement with
AstraZeneca;
•
our payment of $1.5 million to Cornerstone Therapeutics Inc. upon entering into an exclusive worldwide license agreement in August 2010; and
•
aggregate payments of $39.1 million made for operating charges, including costs incurred for third-party research and development services in
connection with clinical-stage product candidates and preclinical programs and personnel and infrastructure costs.
For the
nine months ended September 30, 2009, net cash used in operating activities was principally the result of aggregate payments of $30.5 million made for operating charges, including costs incurred for third-party research and development services
in connection with clinical-stage product candidates and preclinical programs and personnel and infrastructure costs, and was partially offset by our receipt of:
•
the $10.0 million payment from AstraZeneca in July 2009;
36
Table of Contents
•
$4.0 million in collaboration research and development revenue under our preclinical research collaboration with AstraZeneca, which ended in January
2010;
•
$2.5 million in aggregate payments from GlaxoSmithKline upon achievement of milestone events under our alliance agreement;
•
$473,000 in net product sales from sales of Inversine, which we discontinued effective September 30, 2009; and
•
$321,000 under a grant from MJFF.
Net cash used in investing activities for the nine months ended September 30, 2010 was $56.6 million and net cash provided by investing activities for the nine months ended September 30, 2009
was $9.8 million, a difference of $66.4 million. Cash used in investing activities primarily reflects the portion of our cash that we allocate to, and the timing of purchases and maturities of, our investments in marketable securities. The net
purchases of investments in marketable securities for the nine months ended September 30, 2010 were $54.9 million and occurred primarily as a result of our receipt of the upfront payment under our TC-5214 agreement with AstraZeneca. The net
sales of investments in marketable securities for the nine months ended September 30, 2009 were $10.0 million. Additionally, we purchased $1.7 million of property and equipment for the 2010 period, an increase of $1.5 million from $152,000 for
the 2009 period, to expand our internal research and development capacity.
Net cash provided by financing activities for the
nine months ended September 30, 2010 was $4.4 million and net cash used in financing activities for the nine months ended September 30, 2009 was $277,000, a difference of $4.7 million. The change was principally attributable to an increase
for the 2010 period of $1.4 million in proceeds from the issuance of common stock upon the exercise of stock options, the related income tax effect of $2.4 million for the 2010 period and our receipt of $1.2 million in September 2010 under a loan
facility.
Funding Requirements
As of September 30, 2010, we had an accumulated deficit of $216.2 million. We may incur operating losses in future periods as our clinical-stage and preclinical product candidates advance into
later-stage development and as we progress our programs, invest in additional product opportunities and expand our research and development infrastructure. However, we may generate operating income for any particular reporting period as a result of
the recognition into revenue of amounts previously received under our agreements with AstraZeneca and GlaxoSmithKline, including in particular our TC-5214 agreement with AstraZeneca, the timing of milestone events that may be achieved under those
agreements and the timing of costs incurred related to development of our clinical-stage and preclinical product candidates. Our future capital requirements are difficult to forecast and will depend on many factors, including:
•
whether and to what extent milestone events are achieved for TC-5214 under our TC-5214 agreement with AstraZeneca and for AZD3480 and AZD1446 under our
cognitive disorders agreement with AstraZeneca;
37
Table of Contents
•
the progress of, and outcomes from, Phase 3 clinical development of TC-5214 and the amount and timing of development costs for TC-5214 payable by us;
•
whether AstraZeneca exercises its right to license TC-5619 when exercisable;
•
the scope, progress, duration, results and cost of clinical trials, as well as non-clinical studies and assessments, of our other product candidates;
•
the impact on our alliance of GlaxoSmithKline's shift in discovery research focus announced in February 2010 and whether any of our programs in
the therapeutic focus areas of the alliance continue and research and development-related milestone events are achieved;
•
the extent to which we retain development or commercialization rights or responsibilities for our product candidates that are not subject to our
collaborations with AstraZeneca or our alliance with GlaxoSmithKline and incur associated development costs, manufacturing costs or costs to establish sales and marketing functions;
•
whether we establish strategic alliances, collaborations and licensing or other arrangements on terms favorable to us;
•
the costs, timing and outcomes of regulatory reviews or other regulatory actions;
•
the number and characteristics of product candidates that we pursue;
•
the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending patents and other intellectual property
rights;
•
the costs of manufacturing-related services for our product candidates in clinical and late preclinical development;
•
the rate of technological advancements for the indications that we target;
•
the costs to satisfy our obligations under existing and potential future alliances and collaborations;
•
the timing, receipt and amount of sales or royalties, if any, from our potential products; and
•
the extent and scope of our general and administrative expenses.
Implementing our strategy may require additional capital as our clinical-stage and preclinical product candidates advance into
later-stage development and as we progress our programs, invest in additional product opportunities and expand our research and development infrastructure. Our existing capital resources may not be sufficient to enable us to fund the completion of
the
38
Table of Contents
development of any of our product candidates. We currently expect our existing capital resources to be sufficient to fund our operations at least through the end of 2013, without taking into
account any amounts that we would be entitled to receive if milestone events are achieved under either of our collaboration agreements with AstraZeneca or our alliance agreement with GlaxoSmithKline. However, our operating plan may change as a
result of many factors, including those described above, and we may need additional funds sooner than planned to meet operational needs and capital requirements for product development.
To the extent our capital resources are insufficient to meet future capital requirements, we may need to finance future cash needs
through alliances, collaborations or licensing or other arrangements, public or private equity or debt offerings or other financings. The global credit and financial markets continue to be negatively impacted by the recessionary environment. This,
coupled with other factors, may dramatically limit our access to additional equity or debt financing in the future on acceptable terms or at all. Also, additional strategic alliances, collaborations or licensing or other arrangements may not be
available on acceptable terms or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate our research and development programs or obtain funds through arrangements with collaborators or others that
may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently. Additionally, any future equity funding may dilute the ownership of our stockholders.
We cannot determine precisely the completion dates and related costs of our research and development programs due to inherent
uncertainties in outcomes of clinical trials and regulatory approvals of our product candidates. We cannot be certain that we will be able to successfully complete our research and development projects or establish strategic alliances,
collaborations or licensing or other arrangements for our product candidates. Our failure, or the failure of any of our licensees or collaborators, to complete research and development programs for our product candidates could have a material
adverse effect on our financial position or results of operations.

Recent
Accounting Pronouncements
In April 2010, the Financial Accounting Standards Board issued Accounting Standards Update
No. 2010-17,
Milestone Method of Revenue Recognition
, or ASU 2010-17. ASU 2010-17 defines a milestone event and permits an entity to make an accounting policy election to recognize a payment that is contingent upon achievement of a
substantive milestone in its entirety in the period in which the milestone is achieved. ASU 2010-17 is effective for fiscal years beginning on or after June 15, 2010, and for interim periods within those years, and may be applied prospectively
to milestones achieved after the adoption date or retrospectively for all periods presented. Early adoption is permitted. We do not expect ASU 2010-17 to have a material impact on our financial results.
Item 3.
Quantitative and Qualitative Disclosures About Market Risk
The primary objectives of our investment activities are to preserve our capital and meet our liquidity needs to fund our operations. We also seek to generate competitive rates of return from our
investments without assuming significant risk. To achieve our objectives, we maintain a portfolio of cash equivalents and investments in marketable securities that are of high credit quality. As of September 30, 2010, we had cash, cash
equivalents and investments in marketable securities of $268.0 million. Our investments may be subject to interest rate risk and could fall in value if market interest rates increase. However, because our cash equivalents are invested in accounts
with market interest rates and short term in nature and our investments in marketable securities are traded in active markets, we believe that our exposure to interest rate risk is not significant and estimate that an immediate and uniform 10%
increase in market interest rates from levels as of September 30, 2010 would not have a material impact on the total fair value of our portfolio.
We contract for the conduct of some of our clinical trials and other research and development and manufacturing activities with contract research organizations, clinical trial sites and contract
manufacturers in Europe and India. We may be subject to exposure to fluctuations in foreign currency exchange rates in connection with these agreements. If the average Euro/U.S. dollar or Indian Rupee/U.S. dollar exchange rate were to strengthen or
weaken by 10% against the corresponding exchange rate as of September 30, 2010, we estimate that the impact on our financial position, results of operations and cash flows would not be material. We do not hedge our foreign currency exposures.
We have not used derivative financial instruments for speculation or trading purposes.
Item 4.
Controls and Procedures
