                       AFFILIATED COMPUTER SERVICES, INC.

         We provide a full range of information technology services to clients
which have time-critical, transaction-intensive information processing needs.
Our services include technology outsourcing, business process outsourcing and
systems integration services. We are based in Dallas, Texas and have offices
primarily in North America, as well as Central America, South America, Europe,
Africa and the Middle East.

         We were formed in 1988 to participate in the trend to outsource
information processing requirements to third parties which enables businesses to
focus on core operations, respond to rapidly changing technologies and reduce
data processing expenses. Our business strategy is to expand our client base and
enhance our service offerings through both internal marketing and the
acquisition of complementary companies. Our marketing efforts focus on
developing long-term relationships with clients that choose to outsource mission
critical business processes and information technology requirements. Our
revenues have increased from $534 million in fiscal year 1995 to $1.96 billion
in fiscal year 2000, a compound growth rate of 30%. Of this growth,
approximately 14% resulted from internal growth and 16% resulted from growth
through acquisitions. Since inception through December 31, 2000, we have
completed 52 acquisitions, which have resulted in geographic expansion, growth
and diversification of our customer base, expansion of services and products
offered, and increased economies of scale. Approximately 89% of our revenues for
the past three fiscal years were recurring revenues, which are revenues derived
from services that our clients use each year in connection with their ongoing
businesses.

         We provide business process outsourcing, systems integration services
and technology outsourcing in two primary markets. Our largest market is the
commercial sector, which accounts for approximately two-thirds of our annual
revenues and serves a variety of clients nationwide, including retailers, local
municipalities, federal and state agencies, healthcare providers,
telecommunications companies, wholesale distributors, manufacturers, utilities,
financial institutions and insurance companies. We also serve the federal
government market, which accounts for approximately one-third of our annual
revenues. Within our federal government business, approximately half of our
revenues are derived from civilian agencies with the remaining half from
Department of Defense agencies.

         During 2000, we executed a plan to divest certain non-strategic
operations in order to focus on our core information technology outsourcing and
business process outsourcing operations. We sold our ATM processing business,
commercial staffing business and other small professional services businesses.
These business units collectively comprised approximately 15% of fiscal year
2000 consolidated revenues.

         Our principal executive offices are located at 2828 North Haskell
Avenue, Dallas, Texas 75204. Our telephone number at that location is (214)
841-6111.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         This Prospectus contains forward-looking statements. These statements
relate to our, and in some cases our customers' or partners', future plans,
objectives, expectations, intentions and financial performance, and the
assumptions that underlie these statements. In some cases, you can identify
forward-looking statements because they use terms such as "anticipates,"
"believes," "continue," "could," "estimates," "expects," "intends," "may,"
"plans," "potential," "predicts,"



                                       4
<PAGE>   7

"should" or "will" or the negative of those terms or other comparable words.
These statements involve known and unknown risks, uncertainties and other
factors that may cause industry trends or our actual results, level of activity,
performance or achievements to be materially different from any future results,
levels of activity, performance or achievements expressed or implied by these
statements. These factors include those listed under "Risk Factors" and
elsewhere in this Prospectus.

         Although we believe that expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. We will not update any of the
forward-looking statements after the date of this Prospectus to conform these
statements to actual results or changes in our expectations, except as required
by law.

         You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this Prospectus.

                                  RISK FACTORS

         Any investment in the Common Stock involves a high degree of risk. You
should carefully consider the following information about risks, together with
other information contained in this Prospectus, before making an investment
decision. Additional risks and uncertainties not known to us or that we now
believe to be unimportant could also impair our business. If any of the
following risks actually occur, our business, results of operations and
financial condition could suffer significantly. As a result, the market price of
the Common Stock could decline, and you may lose all or a part of your
investment in the Common Stock. Some of the risks that could cause our results
to vary are discussed below.

LOSS OF SIGNIFICANT CLIENTS, SUCH AS THE DEPARTMENT OF EDUCATION OR OTHER MAJOR
CLIENTS, COULD HURT OUR BUSINESS BY REDUCING OUR REVENUES AND PROFITABILITY.

         Our success depends substantially upon retaining our significant
clients. Generally, we may lose clients due to merger or acquisition, business
failure, contract expiration, conversion to a competing service provider or
conversion to an in-house data processing system. We cannot guarantee that we
will be able to retain long-term relationships or secure renewals of short-term
relationships with our significant clients in the future.

         We incur a high level of fixed costs related to our technology
outsourcing and business process outsourcing clients. These fixed costs result
from significant investments in data processing centers, including computer
hardware platforms, computer software, facilities, and client service
infrastructure. The loss of any one of our significant clients could leave us
with a significantly higher level of fixed costs than is necessary to serve our
remaining clients, thereby reducing our profitability.

         We also are vulnerable to reduced processing volumes from our clients,
which could occur due to business downturns, product liability issues, work
stoppages by organized labor, or other business reasons. Many of our clients are
in industries that are currently undergoing significant consolidation. In the
past, we have modified contracts on terms that have been both adverse and
beneficial, and it is possible that future adverse modifications may occur. Our
five



                                       5
<PAGE>   8

largest clients accounted for approximately 18% of our revenue for the fiscal
year ended June 30, 2000. For the fiscal year ended June 30, 1999, our five
largest clients accounted for approximately 19% of our revenue. Approximately 7%
of our revenue in fiscal 2000 and fiscal 1999 came from services performed for
the Department of Education. Our agreement with the Department of Education
expires in September 2003; however, the agreement contains provisions allowing
the Department of Education to terminate the contract prior to the expiration
date without cause. If the Department of Education terminates the contract, we
would generally be reimbursed for the then remaining unamortized costs incurred
with respect to providing the services under the contract, except to the extent
that we are able to use any hardware, software or other resources for other
purposes. Our relationship with the Department of Education is also subject to
the risks of the reduction or modification of the contract due to changing needs
and requirements or to unavailability of funds from the United States
government. Our government contracts allow for termination at any time without
cause and contain extensive audit rights, either of which could hurt our
revenues and profits. We cannot assure you that the Department of Education will
not cancel or modify the contract or that we will maintain our historic level of
revenue or profit from this relationship.

         After the Department of Education, our next four largest clients
accounted for approximately 11% of our revenue in fiscal 2000 and fiscal 1999,
and our agreements with these clients have remaining terms of one to five years.

WE MUST MAKE SIGNIFICANT CAPITAL INVESTMENTS IN ORDER TO ATTRACT AND RETAIN
LARGE OUTSOURCING AGREEMENTS. THESE INVESTMENTS MAY BECOME IMPAIRED IF OUR
CLIENTS' FINANCIAL CONDITION DETERIORATES.

         We must make significant capital investments in order to attract and
retain large outsourcing agreements. We sometimes must purchase assets such as
computing equipment and purchased software, assume financial obligations such as
computer lease and software maintenance obligations, make investments in
securities issued by clients, incur capital expenditures or incur expenses
necessary to provide outsourcing services to a client. We cannot guarantee that
we will be able to finance and properly evaluate these assets and investments.

         We record these investments and asset purchases at fair market value.
We record the remainder of the purchase amount as intangible assets, which are
then amortized over the term of each contract. The termination of a client
contract or the deterioration of the financial condition of a client has in the
past, and may in the future result, in an impairment of the net book value of
the assets recorded.

COMPETITION IN OUR MARKETS COULD FORCE US TO LOWER PRICES OR CAUSE US TO LOSE
BUSINESS TO OUR COMPETITORS.

         We cannot guarantee that we will be able to compete successfully in the
future. We expect to encounter additional competition as we address new markets
and as the computing and communications markets converge. If we are forced to
lower our pricing or if demand for our services decreases, our business,
financial condition, and results of operations will be materially and adversely
affected. Our markets are intensely competitive and highly fragmented. Our
market share represents a small percentage of the total technology services
market. Our clients' requirements and the technology available to satisfy those
requirements continually change. Our



                                       6

principal competitors include Electronic Data Systems Corporation, First Health,
Unisys, Maximus, FYI, Inc., National Processing Company, IBM Global Services,
Computer Sciences Corporation and several other national, regional and local
competitors. Many of our competitors have greater financial, technical, and
operating resources and a larger client base than we do. They may be able to use
their resources to adapt more quickly to new or emerging technologies or to
devote greater resources to the promotion and sale of their products and
services. Many of our largest competitors have a greater international presence
than us and offer a broader range of services. In addition, we must frequently
compete with a client's own internal information technology capability, which
may constitute a fixed cost for the client.

WE MAY HAVE DIFFICULTIES EXECUTING OUR ACQUISITION STRATEGY, WHICH COULD HURT
OUR FUTURE GROWTH AND FINANCIAL CONDITION.

         We intend to continue to expand our business through acquisitions of
companies. Through acquisitions, we intend to expand our geographic presence, to
expand the products and services we offer to existing clients and to enter new
markets. Since our inception in June 1988 through December 31, 2000, we have
completed 52 acquisitions. Approximately one-half of our revenue growth during
the five years ended June 30, 2000 was due to acquisitions. We regularly
evaluate potential acquisition candidates. Risks that we may encounter in our
acquisitions include:

         o        higher acquisition prices due to increased competition for
                  acquisitions;

         o        fewer suitable acquisition candidates at acceptable prices;

         o        insufficient capital resources for acquisitions;

         o        inability to successfully integrate or operate acquired
                  companies;

         o        loss of key management and other employees of acquired
                  companies; and

         o        departure of key clients of acquired companies.

         Although we have not experienced the problem to date, governmental and
regulatory constraints could prevent some acquisitions in the future. We cannot
assure you that any future acquisitions will be successfully integrated or will
be advantageous to us. Without additional acquisitions, we are unlikely to
maintain historical growth rates. If our acquisition strategy fails, our
business, financial condition and results of operations could be materially and
adversely affected.

RAPID TECHNOLOGICAL CHANGES REQUIRE US TO COMMIT SUBSTANTIAL RESOURCES AND COULD
AFFECT OUR ABILITY TO ATTRACT AND RETAIN CLIENTS.

         The markets for our information technology services are subject to
rapid technological changes and rapid changes in client requirements. To
compete, we commit substantial resources to operating multiple hardware
platforms, to customizing third-party software programs and to training client
personnel and our personnel in the use of new technologies. Information
processing is shifting toward client-server and web-based systems, in which
individual computers or groups of personal computers and mid-range systems
replace mainframe systems.



                                       7
<PAGE>   10

This trend could adversely affect our business and financial results. Future
hardware and software products may be able to process large amounts of data more
cost-effectively than existing mainframe platforms which we use in much of our
business.

         We have committed substantial resources to developing outsourcing
solutions for these distributed computing environments, but we cannot guarantee
that we will be successful in customizing products and services that incorporate
new technology on a timely basis. We also cannot guarantee that we will continue
to be able to deliver the services and products demanded by the marketplace.

OUR RELIANCE ON SIGNIFICANT SOFTWARE VENDOR RELATIONSHIPS COULD RESULT IN
SIGNIFICANT EXPENSE OR INABILITY TO SERVE OUR CLIENTS IF WE LOSE THESE
RELATIONSHIPS.

         Our ability to service our clients depends to a large extent on our use
of various software programs that we license from a small number of primary
software vendors. We may not be able to replace them with alternative vendors.
If our significant software vendors assert claims against us for infringement of
intellectual property rights or other claims of breach of our contracts with
them, or if they attempt to re-price our licenses or require us to cure a
claimed breach under a license agreement, we could be required to expend
significant resources to resolve these matters. If our significant vendors were
to terminate or refuse to renew our contracts with them, we might not be able to
replace the related software programs and would be unable to serve our clients.
As a result our business would be materially adversely affected.

OUR CONTRACTS CONTAIN TERMINATION PROVISIONS AND PRICING RISKS THAT CREATE
UNCERTAIN REVENUE STREAMS THAT COULD DECREASE OUR REVENUES AND PROFITABILITY.

         Some of our contracts with clients permit termination in the event our
performance is not consistent with service levels specified in those contracts.
Some of our government clients can terminate their contracts for any reason or
no reason. Our clients' ability to terminate contracts creates an uncertain
revenue stream. If clients are not satisfied with our level of performance, our
reputation in the industry may suffer, which could also materially and adversely
affect our business, financial condition, and results of operations.

         Some of our contracts contain pricing provisions that require the
client to pay a set fee for our services regardless of whether our costs to
perform these services exceed the amount of the set fee. Many of our technology
outsourcing and business process outsourcing contracts provide for credits for
our clients if we fail to achieve specific contract standards. Some of our
contracts contain re-pricing provisions which can result in reductions of our
fees for performing our services. In these situations, we could incur
significant unforeseen costs or financial penalties in performing the contract.

         Technology costs have been dropping for many years and are continuing
to do so due in large part to hardware technology advances. New contracts are
generally priced at lower unit rates than historical contracts. We sometimes
renegotiate client contracts in advance of the scheduled expiration date and
will lower our charges in return for other contractual considerations. If we are
not able to lower our technology costs to keep up with market rates, then our
business, financial condition, and results of operations could be adversely
affected.



                                       8
<PAGE>   11

WE HAVE RISKY INVESTMENTS IN SOME SMALL TECHNOLOGY COMPANIES WHO ARE IN VARIOUS
STAGES OF DEVELOPMENT.

         We have made investments in, and have received equity and/or debt of,
various development-stage or emerging technology companies. We anticipate that
we may continue to periodically make other investments in similar companies. We
are generally a passive investor in such companies and have little or no control
in their development and management. We cannot guarantee that we have properly
evaluated these companies and investments, or that we will be able to do so in
the future. These investments are risky and illiquid, and we may lose some or
all of the amount we have invested. The failure of any of these companies to
develop or effectively execute its business plan may result in an impairment of
the net book value of the assets recorded.

FAILURE TO PROPERLY MANAGE OUR OPERATIONS AND OUR GROWTH COULD HURT OUR ABILITY
TO SERVICE OUR EXISTING CLIENTS, AND COULD IMPEDE OUR ABILITY TO ATTRACT NEW
BUSINESS.

         We have rapidly expanded our operations in recent years. We intend to
continue expansion in the foreseeable future to pursue existing and potential
market opportunities. This rapid growth places a significant demand on our
management and operational resources. In order to manage growth effectively, we
must implement and improve our operational systems, procedures, and controls on
a timely basis. If we fail to implement these systems, procedures and controls
on a timely basis, we may not be able to service our clients' needs, hire and
retain new employees, pursue new business, complete future acquisitions or
operate our businesses effectively. We could also trigger contractual credits to
clients. Failure to properly integrate acquired operations with vendors' systems
could result in increased cost. As a result of any of these problems associated
with expansion, our business, financial condition and results of operations
could be materially and adversely affected.

OUR GOVERNMENT CONTRACTS ALLOW FOR TERMINATION AT ANY TIME WITHOUT CAUSE AND
CONTAIN EXTENSIVE AUDIT RIGHTS, EITHER OF WHICH COULD HURT OUR REVENUES AND
PROFITS.

         Loss or termination of one or more large government contracts could
have a material adverse effect on our business and financial results.
Approximately one-third of our revenue in fiscal 2000 was derived from contracts
with the United States government or its agencies. We have over 103 active prime
contracts and numerous active subcontracts with the United States government or
its agencies. The largest of these contracts accounted for approximately 7% of
our revenue for fiscal 2000 and fiscal 1999. Government contracts, by their
terms, generally can be terminated for convenience by the government. This means
that the government may terminate the contract at any time, without cause. In
some instances, we will receive compensation only for the services provided or
costs incurred at the time of termination. Many of our government contracts
contain base periods of one or more years, as well as one or more option periods
that may cover more than half of the potential contract duration. The government
generally has the right not to exercise the renewal option periods. Its failure
to exercise option periods could curtail the contract term of some of our
government contracts. The government's termination of, or failure to exercise
option periods for, significant government contracts could have a material
adverse effect on our business and financial results.



                                       9
<PAGE>   12

         Government contracts are generally subject to audits and investigations
by government agencies. These audits and investigations involve a review of the
contractor's performance on its contracts, as well as its pricing practices, its
cost structure, and its compliance with applicable laws, regulations and
standards. If the government finds that we improperly charged any costs to a
contract, the costs are not reimbursable. If already reimbursed, the cost must
be refunded to the government. If the government discovers improper or illegal
activities in the course of audits or investigations, the contractor may be
subject to various civil and criminal penalties and administrative sanctions,
which may include termination of contracts, forfeiture of profits, suspension of
payments, fines and suspensions or debarment from doing business with the
government. In recent years, the government has substantially increased the
personnel and resources it devotes to audits and investigations and has
encouraged auditors and investigators to emphasize the detection of fraud or
improper activities. We believe that this high level of industry scrutiny will
continue for the foreseeable future. The government could subject us to similar
scrutiny in the future. Any resulting penalties or sanctions could have a
material adverse effect on our business and financial results.

FEDERAL REGULATIONS RELATING TO CONFIDENTIALITY OF HEALTH DATA COULD REQUIRE US
TO MAKE SIGNIFICANT EXPENDITURES FOR NEW TECHNOLOGY AND SUBJECT US TO INCREASED
COMPLIANCE RISKS.

         In 1996, Congress passed the Health Insurance Portability and
Accountability Act ("HIPAA") which required the Secretary of Health and Human
Services ("HHS") to establish standards for information sharing, security and
confidentiality with regard to health data of individuals. In August 2000, HHS
published final rules relating to the standardization of information used in
common healthcare information processing transactions, which rules require
compliance by October 2002. In December 2000, HHS published its final health
data privacy regulations which will take effect in April 2003. These regulations
restrict the use and disclosure of personally identifiable health information
without the prior consent and/or authorization of the patient. HHS has not yet
issued final rules on the security provisions under HIPAA and has indicated that
it will issue further guidelines and enforcement advice on the regulations it
has issued in final form. The final security rules, if and when issued, and the
guidelines and enforcement advice may differ from the proposed security rules
and the other currently-final regulations. We cannot predict the potential
impact of the final rules or the anticipated changes in the currently-final
regulations. In addition, the Texas legislature is currently considering similar
legislation that will address medical record privacy and restrict the uses and
disclosures of individually identifiable health information, and other federal
or state privacy legislation may be enacted at any time.

         These laws or regulations, if and when adopted, could restrict our
ability to obtain, use, process or disseminate the individually identifiable
health information of our employees and the employees of our processing clients.
We process personally identifiable health data for many of our clients. In
connection with our services we and our clients will be required to comply with
HIPAA. We may be required to implement new technology and security features to
protect the privacy and integrity of such health data. Our compliance with these
new laws or regulations could require significant expenditures on our part.
Expenditures necessary for our own internal HIPAA compliance will not be
directly chargeable to our clients.

         While we believe that our compliance efforts undertaken on behalf of
our clients will result in an increase in our charges to such clients, we cannot
guarantee that such increases will



                                       10
<PAGE>   13

occur. Furthermore, HIPAA subjects us in certain instances, as a service
provider, to liability and monetary penalties for failure to comply with HIPAA
when processing personally identifiable health data maintained by our clients.
If we fail to comply with HIPAA in connection with such processing services, we
could incur liability under these provisions.

OUR HIGH TURNOVER OF TECHNICALLY SKILLED EMPLOYEES REQUIRES THAT WE DEVOTE
SUBSTANTIAL RESOURCES TO ATTRACT AND RETAIN THEM. THE FAILURE TO ATTRACT AND
RETAIN TECHNICAL PERSONNEL AND SKILLED MANAGEMENT COULD HURT OUR ABILITY TO GROW
AND MANAGE OUR BUSINESS.

         Our success depends to a significant extent upon our ability to
attract, retain and motivate highly skilled and qualified personnel. If we fail
to attract, train, and retain sufficient numbers of these technically-skilled
people, our business, financial condition, and results of operations will be
materially and adversely affected. Competition for personnel is intense in the
information technology services industry, and recruiting and training personnel
requires substantial resources. We must continue to grow internally by hiring
and training technically-skilled people in order to perform services under our
existing contracts and new contracts that we will enter into. The people capable
of filling these positions are in great demand and recruiting and training these
personnel require substantial resources. Despite increasing our expenditures to
hire and retain a technically-skilled workforce, our business still experiences
significant turnover. Our success also depends on the skills, experience, and
performance of key members of our management team. The loss of any key employee
could have an adverse effect on our business, financial condition and results of
operations and prospects. Other than with Darwin Deason, we have not entered
into employment agreements with any of our key personnel, although we have
entered into severance agreements with certain of our executive officers and we
may in the future enter into employment agreements with our key personnel.

DARWIN DEASON HAS SUBSTANTIAL CONTROL OVER OUR COMPANY AND CAN AFFECT VIRTUALLY
ALL DECISIONS MADE BY OUR STOCKHOLDERS.

         Darwin Deason, our Chairman of the Board, beneficially owns 3,299,686
shares of Class B Common Stock and 2,504,174 shares of the Common Stock as of
March 1, 2001. Mr. Deason controls approximately 45% of the total voting power
of the Company (based on total shares of common stock outstanding as of March 1,
2001). As a result, Mr. Deason has the requisite voting power to significantly
affect virtually all decisions made by the Company and our stockholders,
including the power to block corporate actions such as an amendment to most
provisions of our certificate of incorporation. In addition, Mr. Deason may
significantly influence the election of directors and any other action requiring
shareholder approval. Mr. Deason serves as the one-person nominations committee
to our Board of Directors and thus recommends management's slate of directors to
be proposed by the Board to our shareholders. In the spring of 1999, Mr. Deason
was succeeded by Jeffrey A. Rich as Chief Executive Officer. Mr. Deason has an
employment contract including severance arrangements, which has an expiration
date of May 2004, and is annually renewable thereafter.

LEGAL PROCEEDINGS, INCLUDING A $17 MILLION JUDGMENT, COULD RESULT IN MATERIAL
CHARGES AGAINST EARNINGS.



                                       11
<PAGE>   14

         On December 16, 1998, a state district court in Houston, Texas entered
final judgment against us in a lawsuit brought by twenty-one former employees of
Gibraltar Savings Association and/or First Texas Savings Association
(collectively, "GSA/FTSA"). The GSA/FTSA employees alleged that they were
entitled to the value of 401,541 shares of our stock pursuant to options issued
to the GSA/FTSA employees in 1988 in connection with a former data processing
services agreement between GSA/FTSA and us. The judgment against us was for
approximately $17,000,000, which includes attorneys' fees and pre-judgment
interest, but excludes additional attorneys' fees of approximately $850,000
which could be awarded in the event the plaintiffs are successful upon appeal
and final judgment. We continue to believe that we have meritorious defenses to
all or a substantial portion of the plaintiffs' claims. We filed our appeal of
the judgment on March 15, 1999 and are vigorously pursuing the appeal. The
plaintiffs also filed a notice of appeal and are pursuing their appeal. Should
the proceedings not be favorably resolved on appeal, we would be subject to a
charge equal to the amount of any final judgment, fees and interest awarded in
favor of the plaintiffs.

         Government contracts are subject to review and audit by various
governmental authorities in the normal course of our business. Cost audits have
been completed through fiscal 1998 for a majority of the federal government
business operations. In management's opinion, any such reviews and the results
of cost audits for subsequent fiscal years will not have a material effect on
our financial position or results of operations.

         We are subject to certain other legal proceedings, claims and disputes
which arise in the ordinary course of business. Although we cannot predict the
outcomes of these legal proceedings, management does not believe these actions,
in the aggregate, will have a material adverse effect on our financial position,
results of operations or liquidity.

PROVISIONS OF OUR CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE LAW COULD
DETER TAKEOVER ATTEMPTS THAT STOCKHOLDERS MAY THINK ARE IN THEIR BEST INTERESTS.

         Some provisions in our certificate of incorporation and bylaws could
also delay, defer, prevent or make more difficult a merger, tender offer, or
proxy contest involving our capital stock. Our stockholders might view
transactions such as these as being in their best interests because, for
example, a change of control might result in a price higher than the market
price for shares of the Common Stock. Among other things, these provisions:

         o        require an 80% vote of the stockholders to amend some
                  provisions of our certificate of incorporation;

         o        require an 80% vote of the stockholders to amend some
                  provisions of our bylaws;

         o        permit only our Chairman, President or a majority of the Board
                  of Directors to call stockholder meetings;

         o        authorize our Board of Directors to issue up to 3,000,000
                  shares of preferred stock in series with the terms of each
                  series to be fixed by our Board of Directors;

         o        authorize our Board of Directors to issue Class B Common
                  Stock, which shares are entitled to ten votes per share;



                                       12
<PAGE>   15

         o        permit directors to be removed, with or without cause, only by
                  a vote of at least 80% of the combined voting power; and

         o        specify advance notice requirements for stockholder proposals
                  and director nominations to be considered at a meeting of
                  stockholders.

         In addition, with some exceptions, Section 203 of the Delaware General
Corporation Law restricts mergers and other business combinations between us and
any holder of 15% or more of our voting stock.

         We also have a stockholder rights plan. Under this plan, after the
occurrence of specified events, our stockholders will be able to buy stock from
us or our successor at reduced prices. These rights will not extend, however, to
persons participating in takeover attempts without the consent of our Board of
Directors. Accordingly, this plan could delay, defer or prevent a change of
control of our company.

         Further, we have entered into severance agreements with certain of our
executive officers, which may have the effect of discouraging an unsolicited
takeover proposal. Finally, Mr. Deason's ownership of approximately 45% of the
voting power of our capital stock could have the effect of delaying, deterring
or preventing a takeover of our company. See "Darwin Deason has substantial
control over our company and can affect virtually all decisions made by our
stockholders" for additional information about Mr. Deason's ownership.

INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS COULD REQUIRE US TO INCUR SUBSTANTIAL
COSTS TO DEFEND THE CLAIMS, CHANGE OUR SERVICES, PURCHASE NEW LICENSES OR
REDESIGN OUR USE OF CHALLENGED TECHNOLOGY.

         We and other companies in our industry rely heavily on the use of
intellectual property. We do not own the majority of the software that we use to
run our business; instead we license this software from a small number of
primary vendors. If these vendors assert claims that we or our clients are
infringing on their software or related intellectual property, we could incur
substantial costs to defend these claims.

         In addition, if any of our vendors' infringement claims are ultimately
successful, our vendors could require us (1) to cease selling or using products
or services that incorporate the challenged software or technology, (2) to
obtain a license or additional licenses from our vendors, or (3) to redesign our
products and services which rely on the challenged software or technology. We
are not currently involved in any material intellectual property litigation, but
could be in the future to protect our trade secrets or know-how, or to defend
ourselves or our clients against alleged infringement claims.

AVAILABILITY OF SIGNIFICANT AMOUNTS OF THE COMMON STOCK FOR SALE COULD CAUSE THE
MARKET PRICE OF THE COMMON STOCK TO DROP.

         There is a substantial number of shares of the Common Stock that may be
issued and subsequently sold under the Plans, upon exercise of employee stock
options, and upon conversion of our Class B Common Stock, our 4% convertible
subordinated notes and our 3.5%



                                       13
<PAGE>   16

convertible subordinated notes. The sale or issuance of additional shares of the
Common Stock could adversely affect the prevailing market price of the Common
Stock.

WE MAY, IN THE FUTURE, BE EXPOSED TO RISKS RELATED TO INTERNATIONAL OPERATIONS
WHICH COULD INCREASE OUR COSTS AND HURT OUR BUSINESS.

         We currently have limited operations in many countries around the world
but may increase our international presence in the future. Risks that affect
international operations include:

         o        fluctuations in currency exchange rates;

         o        complicated licensing and work permit requirements;

         o        variations in the protection of intellectual property rights;

         o        restrictions on the ability to convert currency; and

         o        additional expenses and risks inherent in conducting
                  operations in geographically distant locations, with clients
                  speaking different languages and having different cultural
                  approaches to the conduct of business.

THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY, WHICH MAY RESULT IN
LOSSES FOR INVESTORS.

         The market price for the Common Stock has been and may continue to be
volatile. For example, during the 52-week period ended February 28, 2001, the
closing prices of the Common Stock as reported on the New York Stock Exchange
ranged from a high of $68.40 to a low of $31.31. We expect our stock price to be
subject to fluctuations as a result of a variety of factors, including factors
beyond our control. These factors include:

         o        actual or anticipated variations in our quarterly operating
                  results;

         o        announcements of technological innovations or new products or
                  services by us or our competitors;

         o        announcements relating to strategic relationships or
                  acquisitions;

         o        changes in financial estimates or other statements by
                  securities analysts;

         o        changes in general economic conditions;

         o        conditions or trends affecting the outsourcing industry; and

         o        changes in the economic performance and/or market valuations
                  of other information technology companies.



                                       14
<PAGE>   17

         Because of this volatility, we may fail to meet the expectations of our
stockholders or of securities analysts at some time in the future, and our stock
price and therefore the price of our notes could decline as a result.

         In addition, the stock market has experienced significant price and
volume fluctuations that have particularly affected the trading prices of equity
securities of many high technology companies. These fluctuations have often been
unrelated or disproportionate to changes in the operating performance of these
companies. Any negative change in the public's perception of information
technology companies could depress our stock price regardless of our operating
results.

OTHER RISKS, UNKNOWN OR IMMATERIAL TODAY, MAY BECOME KNOWN OR MATERIAL IN THE
FUTURE.

         We have attempted to identify material risk factors currently affecting
our business and company. However, additional risks that we do not yet know of,
or that we currently think are immaterial, may occur or become material. These
risks could impair our business operations or adversely affect revenues or
profitability.

                                 USE OF PROCEEDS

         The Company will not receive any of the proceeds from the sale of the
Common Stock by the Selling Stockholders to the public pursuant to this
Prospectus. All proceeds from the sale of the Common Stock by the Selling
Stockholders will be for the account of the Selling Stockholders.

                              SELLING STOCKHOLDERS

         The following table lists the names of certain Selling Stockholders and
the number of shares of the Common Stock to be sold by them pursuant to this

*        All Selling Stockholders will own less than 1% of the outstanding
         shares of the Common Stock after the offering.

(1)      Represents shares of the Common Stock beneficially owned by the named
         individual as of May 30, 2001.

(2)      Does not constitute a commitment to sell any or all of the stated
         number of shares of the Common Stock. The number of shares of the
         Common Stock offered shall be determined from time to time by each
         Selling Stockholder in his or her sole discretion.

                              PLAN OF DISTRIBUTION

         The Selling Stockholders may sell all or a portion of the shares of the
Common Stock from time to time under this Prospectus in one or more transactions
on the New York Stock Exchange, or other exchange, in a negotiated transaction
or in a combination of such methods of sale, at market prices prevailing at the
time of sale, at prices related to such prevailing market prices or at prices
otherwise negotiated. The Selling Stockholders may effect such transactions by
selling the shares of the Common Stock to or through broker-dealers, and such
broker-dealers may receive compensation in the form of underwriting discounts,
concessions or commissions from the Selling Stockholders and/or the purchasers
of the shares of the Common Stock for whom such broker-dealers may act as agent
(which compensation may be less than or in excess of customary commissions).

         The Selling Stockholders and any broker-dealers that participate in the
distribution of the shares of the Common Stock may be deemed to be
"underwriters" within the meaning of Section 2(11) of the Act, and any
commissions received by them and any profit on the resale of the shares of the
Common Stock sold by them may be deemed to be underwriting discounts and
commissions under the Act. All selling and other expenses incurred by the
Selling Stockholders will be borne by the Selling Stockholders.

         In addition to any shares of the Common Stock sold hereunder, the
Selling Stockholders may, at the same time, sell any other shares of the Common
Stock, owned by them in compliance with all of the requirements of Rule 144,
regardless of whether such shares of the Common Stock are covered by this
Prospectus.

         There is no assurance that the Selling Stockholders will sell all or
any portion of the shares of the Common Stock covered by this Prospectus.

         The Company will pay all expenses related to registering the shares of
the Common Stock covered by this Prospectus and will not receive any proceeds
from sales of any such shares of the Common Stock by the Selling Stockholders to
the public.

                                  LEGAL MATTERS

         The validity of the Common Stock issuable under the Plans has been
passed upon for us by Jackson Walker L.L.P., Dallas, Texas.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Delaware General Corporation Law (the "DGCL") authorizes Delaware
corporations to limit the liability of directors and officers to the corporation
or its stockholders for money damages, except for (a) breaches of a director's
duty of loyalty to the corporation or its stockholders; (b) acts or omissions
not in good faith or involving intentional misconduct or knowing violations of
the law; (c) the payment of unlawful dividends or unlawful stock repurchases or
redemptions; or (d) transactions in which the director received an improper
personal benefit. The DGCL, unless limited by the corporation's charter,
provides that indemnification is mandatory to the extent that a director,
officer, employee or agent, acting in good faith, and in a manner that he or she
reasonably believes to be in, or not opposed to, the best interests of the
corporation, or with respect to any criminal action or proceeding, there was no
reason to believe that his or her conduct was unlawful, or has been successful
on the merits or otherwise in the defense of any proceeding covered by the
indemnification statute. The DGCL generally permits indemnification for expenses
incurred in the defense or settlement of derivative or third party actions,
provided that there is a determination by a majority vote of the directors who
are not parties to the action even though less than a quorum, or by a committee
of directors designated by a majority vote of the directors, even though less
than a quorum, or if such directors so direct, by independent legal counsel in a
written opinion, or by the stockholders, that the person seeking indemnification
acted in good faith and in a manner reasonably believed to be in, or not opposed
to, the best interests of the corporation, or in a criminal proceeding that the
person had no reason to believe that his or her conduct to be unlawful. Without
court approval, however, no indemnification may be made in respect of any
derivative action in which such person is adjudged liable. The DGCL states that
the indemnification provided by the statute shall not be deemed exclusive of any
other rights under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

         Article Ninth of the Certificate of Incorporation of the Company limits
the liability of directors and officers to the fullest extent permitted by the
DGCL. Article Ninth of the Charter of the Company also authorizes the Company to
enter into contracts, adopt bylaws or resolutions to provide for the
indemnification of the Company's directors and officers. Section 33 of the


<PAGE>   23

Company's bylaws provides for the indemnification of the Company's directors and
officers to the fullest extent permitted by the DGCL. In addition, the Company's
directors and officers are covered by certain insurance policies maintained by
the Company.

         Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers or persons controlling the Company pursuant to
the foregoing provisions, the Company has been informed that in the opinion of
the Commission, such indemnification is against public policy as expressed in
the Act and is therefore unenforceable.

ITEM 9.           UNDERTAKINGS.

         (a)      The Company hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:


<PAGE>   24

                           (i) To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in this Registration
Statement;

                  (2) That, for the purpose of determining any liability under
the Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Company hereby undertakes that, for purposes of determining any
liability under the Act, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
filing of the Plans' annual reports pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                     500,000 SHARES OF CLASS A COMMON STOCK

         This prospectus (this "Prospectus") relates to the offer and sale of up
to 500,000 shares of Class A common stock, par value $0.01 (the "Common Stock")
of Affiliated Computer Services, Inc. (the "Company") from time to time by the
stockholders of the Company identified on pages 15, 16 and 17 of this Prospectus

trading, at such prices and upon such terms as may be obtainable.

         Upon any sale of the Common Stock offered hereby, the Selling
Stockholders and participating agents, brokers, dealers or market makers may be
deemed to be underwriters as that term is defined in the Securities Act of 1933,
as amended (the "Act"), and commissions or discounts or any profit realized on
the resale of such securities purchased by them may be deemed to be underwriting
commissions or discounts under the Act. The Company will not receive any of the
proceeds from the sales by the Selling Stockholders.

         No underwriter is being utilized in connection with this offering. The
Company will pay all expenses incurred in connection with this offering.

in fiscal year 2000, a compound growth rate of 30%. Of this growth,
approximately 14% resulted from internal growth and 16% resulted from growth
through acquisitions. Since inception through December 31, 2000, we have
completed 52 acquisitions, which have resulted in geographic expansion, growth
and diversification of our customer base, expansion of services and products
offered, and increased economies of scale. Approximately 89% of our revenues for
the past three fiscal years were recurring revenues, which are revenues derived
from services that our clients use each year in connection with their ongoing
businesses.

         We provide business process outsourcing, systems integration services
and technology outsourcing in two primary markets. Our largest market is the
commercial sector, which accounts for approximately two-thirds of our annual
revenues and serves a variety of clients nationwide, including retailers, local
municipalities, federal and state agencies, healthcare providers,
telecommunications companies, wholesale distributors, manufacturers, utilities,
financial institutions and insurance companies. We also serve the federal
government market, which accounts for approximately one-third of our annual
revenues. Within our federal government business, approximately half of our
revenues are derived from civilian agencies with the remaining half from
Department of Defense agencies.

         During 2000, we executed a plan to divest certain non-strategic
operations in order to focus on our core information technology outsourcing and
business process outsourcing operations. We sold our ATM processing business,
commercial staffing business and other small professional services businesses.
These business units collectively comprised approximately 15% of fiscal year
2000 consolidated revenues.

         Our principal executive offices are located at 2828 North Haskell
Avenue, Dallas, Texas 75204. Our telephone number at that location is (214)
841-6111.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         This Prospectus contains forward-looking statements. These statements
relate to our, and in some cases our customers' or partners', future plans,
objectives, expectations, intentions and financial performance, and the
assumptions that underlie these statements. In some cases, you can identify
forward-looking statements because they use terms such as "anticipates,"
"believes," "continue," "could," "estimates," "expects," "intends," "may,"
"plans," "potential," "predicts,"

                                       4
7

"should" or "will" or the negative of those terms or other comparable words.
These statements involve known and unknown risks, uncertainties and other
factors that may cause industry trends or our actual results, level of activity,
performance or achievements to be materially different from any future results,
levels of activity, performance or achievements expressed or implied by these
statements. These factors include those listed under "Risk Factors" and
elsewhere in this Prospectus.

         Although we believe that expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. We will not update any of the
forward-looking statements after the date of this Prospectus to conform these
statements to actual results or changes in our expectations, except as required
by law.

         You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this Prospectus.

                                  RISK FACTORS

         Any investment in the Common Stock involves a high degree of risk. You
should carefully consider the following information about risks, together with
other information contained in this Prospectus, before making an investment
decision. Additional risks and uncertainties not known to us or that we now
believe to be unimportant could also impair our business. If any of the
following risks actually occur, our business, results of operations and
financial condition could suffer significantly. As a result, the market price of
the Common Stock could decline, and you may lose all or a part of your
investment in the Common Stock. Some of the risks that could cause our results
to vary are discussed below.

LOSS OF SIGNIFICANT CLIENTS, SUCH AS THE DEPARTMENT OF EDUCATION OR OTHER MAJOR
CLIENTS, COULD HURT OUR BUSINESS BY REDUCING OUR REVENUES AND PROFITABILITY.

         Our success depends substantially upon retaining our significant
clients. Generally, we may lose clients due to merger or acquisition, business
failure, contract expiration, conversion to a competing service provider or
conversion to an in-house data processing system. We cannot guarantee that we
will be able to retain long-term relationships or secure renewals of short-term
relationships with our significant clients in the future.

         We incur a high level of fixed costs related to our technology
outsourcing and business process outsourcing clients. These fixed costs result
from significant investments in data processing centers, including computer
hardware platforms, computer software, facilities, and client service
infrastructure. The loss of any one of our significant clients could leave us
with a significantly higher level of fixed costs than is necessary to serve our
remaining clients, thereby reducing our profitability.

         We also are vulnerable to reduced processing volumes from our clients,
which could occur due to business downturns, product liability issues, work
stoppages by organized labor, or other business reasons. Many of our clients are
in industries that are currently undergoing significant consolidation. In the
past, we have modified contracts on terms that have been both adverse and
beneficial, and it is possible that future adverse modifications may occur. Our
five

                                       5
8

largest clients accounted for approximately 18% of our revenue for the fiscal
year ended June 30, 2000. For the fiscal year ended June 30, 1999, our five
largest clients accounted for approximately 19% of our revenue. Approximately 7%
of our revenue in fiscal 2000 and fiscal 1999 came from services performed for
the Department of Education. Our agreement with the Department of Education
expires in September 2003; however, the agreement contains provisions allowing
the Department of Education to terminate the contract prior to the expiration
date without cause. If the Department of Education terminates the contract, we
would generally be reimbursed for the then remaining unamortized costs incurred
with respect to providing the services under the contract, except to the extent
that we are able to use any hardware, software or other resources for other
purposes. Our relationship with the Department of Education is also subject to
the risks of the reduction or modification of the contract due to changing needs
and requirements or to unavailability of funds from the United States
government. Our government contracts allow for termination at any time without
cause and contain extensive audit rights, either of which could hurt our
revenues and profits. We cannot assure you that the Department of Education will
not cancel or modify the contract or that we will maintain our historic level of
revenue or profit from this relationship.

         After the Department of Education, our next four largest clients
accounted for approximately 11% of our revenue in fiscal 2000 and fiscal 1999,
and our agreements with these clients have remaining terms of one to five years.

WE MUST MAKE SIGNIFICANT CAPITAL INVESTMENTS IN ORDER TO ATTRACT AND RETAIN
LARGE OUTSOURCING AGREEMENTS. THESE INVESTMENTS MAY BECOME IMPAIRED IF OUR
CLIENTS' FINANCIAL CONDITION DETERIORATES.

         We must make significant capital investments in order to attract and
retain large outsourcing agreements. We sometimes must purchase assets such as
computing equipment and purchased software, assume financial obligations such as
computer lease and software maintenance obligations, make investments in
securities issued by clients, incur capital expenditures or incur expenses
necessary to provide outsourcing services to a client. We cannot guarantee that
we will be able to finance and properly evaluate these assets and investments.

         We record these investments and asset purchases at fair market value.
We record the remainder of the purchase amount as intangible assets, which are
then amortized over the term of each contract. The termination of a client
contract or the deterioration of the financial condition of a client has in the
past, and may in the future result, in an impairment of the net book value of
the assets recorded.

COMPETITION IN OUR MARKETS COULD FORCE US TO LOWER PRICES OR CAUSE US TO LOSE
BUSINESS TO OUR COMPETITORS.

         We cannot guarantee that we will be able to compete successfully in the
future. We expect to encounter additional competition as we address new markets
and as the computing and communications markets converge. If we are forced to
lower our pricing or if demand for our services decreases, our business,
financial condition, and results of operations will be materially and adversely
affected. Our markets are intensely competitive and highly fragmented. Our
market share represents a small percentage of the total technology services
market. Our clients' requirements and the technology available to satisfy those
requirements continually change. Our

                                       6
9

principal competitors include Electronic Data Systems Corporation, First Health,
Unisys, Maximus, FYI, Inc., National Processing Company, IBM Global Services,
Computer Sciences Corporation and several other national, regional and local
competitors. Many of our competitors have greater financial, technical, and
operating resources and a larger client base than we do. They may be able to use
their resources to adapt more quickly to new or emerging technologies or to
devote greater resources to the promotion and sale of their products and
services. Many of our largest competitors have a greater international presence
than us and offer a broader range of services. In addition, we must frequently
compete with a client's own internal information technology capability, which
may constitute a fixed cost for the client.

WE MAY HAVE DIFFICULTIES EXECUTING OUR ACQUISITION STRATEGY, WHICH COULD HURT
OUR FUTURE GROWTH AND FINANCIAL CONDITION.

         We intend to continue to expand our business through acquisitions of
companies. Through acquisitions, we intend to expand our geographic presence, to
expand the products and services we offer to existing clients and to enter new
markets. Since our inception in June 1988 through December 31, 2000, we have
completed 52 acquisitions. Approximately one-half of our revenue growth during
the five years ended June 30, 2000 was due to acquisitions. We regularly
evaluate potential acquisition candidates. Risks that we may encounter in our
acquisitions include:

         o        higher acquisition prices due to increased competition for
                  acquisitions;

         o        fewer suitable acquisition candidates at acceptable prices;

         o        insufficient capital resources for acquisitions;

         o        inability to successfully integrate or operate acquired
                  companies;

         o        loss of key management and other employees of acquired
                  companies; and

         o        departure of key clients of acquired companies.

         Although we have not experienced the problem to date, governmental and
regulatory constraints could prevent some acquisitions in the future. We cannot
assure you that any future acquisitions will be successfully integrated or will
be advantageous to us. Without additional acquisitions, we are unlikely to
maintain historical growth rates. If our acquisition strategy fails, our
business, financial condition and results of operations could be materially and
adversely affected.

RAPID TECHNOLOGICAL CHANGES REQUIRE US TO COMMIT SUBSTANTIAL RESOURCES AND COULD
AFFECT OUR ABILITY TO ATTRACT AND RETAIN CLIENTS.

         The markets for our information technology services are subject to
rapid technological changes and rapid changes in client requirements. To
compete, we commit substantial resources to operating multiple hardware
platforms, to customizing third-party software programs and to training client
personnel and our personnel in the use of new technologies. Information
processing is shifting toward client-server and web-based systems, in which
individual computers or groups of personal computers and mid-range systems
replace mainframe systems.

                                       7
10

This trend could adversely affect our business and financial results. Future
hardware and software products may be able to process large amounts of data more
cost-effectively than existing mainframe platforms which we use in much of our
business.

         We have committed substantial resources to developing outsourcing
solutions for these distributed computing environments, but we cannot guarantee
that we will be successful in customizing products and services that incorporate
new technology on a timely basis. We also cannot guarantee that we will continue
to be able to deliver the services and products demanded by the marketplace.

OUR RELIANCE ON SIGNIFICANT SOFTWARE VENDOR RELATIONSHIPS COULD RESULT IN
SIGNIFICANT EXPENSE OR INABILITY TO SERVE OUR CLIENTS IF WE LOSE THESE
RELATIONSHIPS.

         Our ability to service our clients depends to a large extent on our use
of various software programs that we license from a small number of primary
software vendors. We may not be able to replace them with alternative vendors.
If our significant software vendors assert claims against us for infringement of
intellectual property rights or other claims of breach of our contracts with
them, or if they attempt to re-price our licenses or require us to cure a
claimed breach under a license agreement, we could be required to expend
significant resources to resolve these matters. If our significant vendors were
to terminate or refuse to renew our contracts with them, we might not be able to
replace the related software programs and would be unable to serve our clients.
As a result our business would be materially adversely affected.

OUR CONTRACTS CONTAIN TERMINATION PROVISIONS AND PRICING RISKS THAT CREATE
UNCERTAIN REVENUE STREAMS THAT COULD DECREASE OUR REVENUES AND PROFITABILITY.

         Some of our contracts with clients permit termination in the event our
performance is not consistent with service levels specified in those contracts.
Some of our government clients can terminate their contracts for any reason or
no reason. Our clients' ability to terminate contracts creates an uncertain
revenue stream. If clients are not satisfied with our level of performance, our
reputation in the industry may suffer, which could also materially and adversely
affect our business, financial condition, and results of operations.

         Some of our contracts contain pricing provisions that require the
client to pay a set fee for our services regardless of whether our costs to
perform these services exceed the amount of the set fee. Many of our technology
outsourcing and business process outsourcing contracts provide for credits for
our clients if we fail to achieve specific contract standards. Some of our
contracts contain re-pricing provisions which can result in reductions of our
fees for performing our services. In these situations, we could incur
significant unforeseen costs or financial penalties in performing the contract.

         Technology costs have been dropping for many years and are continuing
to do so due in large part to hardware technology advances. New contracts are
generally priced at lower unit rates than historical contracts. We sometimes
renegotiate client contracts in advance of the scheduled expiration date and
will lower our charges in return for other contractual considerations. If we are
not able to lower our technology costs to keep up with market rates, then our
business, financial condition, and results of operations could be adversely
affected.

                                       8
11

WE HAVE RISKY INVESTMENTS IN SOME SMALL TECHNOLOGY COMPANIES WHO ARE IN VARIOUS
STAGES OF DEVELOPMENT.

         We have made investments in, and have received equity and/or debt of,
various development-stage or emerging technology companies. We anticipate that
we may continue to periodically make other investments in similar companies. We
are generally a passive investor in such companies and have little or no control
in their development and management. We cannot guarantee that we have properly
evaluated these companies and investments, or that we will be able to do so in
the future. These investments are risky and illiquid, and we may lose some or
all of the amount we have invested. The failure of any of these companies to
develop or effectively execute its business plan may result in an impairment of
the net book value of the assets recorded.

FAILURE TO PROPERLY MANAGE OUR OPERATIONS AND OUR GROWTH COULD HURT OUR ABILITY
TO SERVICE OUR EXISTING CLIENTS, AND COULD IMPEDE OUR ABILITY TO ATTRACT NEW
BUSINESS.

         We have rapidly expanded our operations in recent years. We intend to
continue expansion in the foreseeable future to pursue existing and potential
market opportunities. This rapid growth places a significant demand on our
management and operational resources. In order to manage growth effectively, we
must implement and improve our operational systems, procedures, and controls on
a timely basis. If we fail to implement these systems, procedures and controls
on a timely basis, we may not be able to service our clients' needs, hire and
retain new employees, pursue new business, complete future acquisitions or
operate our businesses effectively. We could also trigger contractual credits to
clients. Failure to properly integrate acquired operations with vendors' systems
could result in increased cost. As a result of any of these problems associated
with expansion, our business, financial condition and results of operations
could be materially and adversely affected.

OUR GOVERNMENT CONTRACTS ALLOW FOR TERMINATION AT ANY TIME WITHOUT CAUSE AND
CONTAIN EXTENSIVE AUDIT RIGHTS, EITHER OF WHICH COULD HURT OUR REVENUES AND
PROFITS.

         Loss or termination of one or more large government contracts could
have a material adverse effect on our business and financial results.
Approximately one-third of our revenue in fiscal 2000 was derived from contracts
with the United States government or its agencies. We have over 103 active prime
contracts and numerous active subcontracts with the United States government or
its agencies. The largest of these contracts accounted for approximately 7% of
our revenue for fiscal 2000 and fiscal 1999. Government contracts, by their
terms, generally can be terminated for convenience by the government. This means
that the government may terminate the contract at any time, without cause. In
some instances, we will receive compensation only for the services provided or
costs incurred at the time of termination. Many of our government contracts
contain base periods of one or more years, as well as one or more option periods
that may cover more than half of the potential contract duration. The government
generally has the right not to exercise the renewal option periods. Its failure
to exercise option periods could curtail the contract term of some of our
government contracts. The government's termination of, or failure to exercise
option periods for, significant government contracts could have a material
adverse effect on our business and financial results.

                                       9
12

         Government contracts are generally subject to audits and investigations
by government agencies. These audits and investigations involve a review of the
contractor's performance on its contracts, as well as its pricing practices, its
cost structure, and its compliance with applicable laws, regulations and
standards. If the government finds that we improperly charged any costs to a
contract, the costs are not reimbursable. If already reimbursed, the cost must
be refunded to the government. If the government discovers improper or illegal
activities in the course of audits or investigations, the contractor may be
subject to various civil and criminal penalties and administrative sanctions,
which may include termination of contracts, forfeiture of profits, suspension of
payments, fines and suspensions or debarment from doing business with the
government. In recent years, the government has substantially increased the
personnel and resources it devotes to audits and investigations and has
encouraged auditors and investigators to emphasize the detection of fraud or
improper activities. We believe that this high level of industry scrutiny will
continue for the foreseeable future. The government could subject us to similar
scrutiny in the future. Any resulting penalties or sanctions could have a
material adverse effect on our business and financial results.

FEDERAL REGULATIONS RELATING TO CONFIDENTIALITY OF HEALTH DATA COULD REQUIRE US
TO MAKE SIGNIFICANT EXPENDITURES FOR NEW TECHNOLOGY AND SUBJECT US TO INCREASED
COMPLIANCE RISKS.

         In 1996, Congress passed the Health Insurance Portability and
Accountability Act ("HIPAA") which required the Secretary of Health and Human
Services ("HHS") to establish standards for information sharing, security and
confidentiality with regard to health data of individuals. In August 2000, HHS
published final rules relating to the standardization of information used in
common healthcare information processing transactions, which rules require
compliance by October 2002. In December 2000, HHS published its final health
data privacy regulations which will take effect in April 2003. These regulations
restrict the use and disclosure of personally identifiable health information
without the prior consent and/or authorization of the patient. HHS has not yet
issued final rules on the security provisions under HIPAA and has indicated that
it will issue further guidelines and enforcement advice on the regulations it
has issued in final form. The final security rules, if and when issued, and the
guidelines and enforcement advice may differ from the proposed security rules
and the other currently-final regulations. We cannot predict the potential
impact of the final rules or the anticipated changes in the currently-final
regulations. In addition, the Texas legislature is currently considering similar
legislation that will address medical record privacy and restrict the uses and
disclosures of individually identifiable health information, and other federal
or state privacy legislation may be enacted at any time.

         These laws or regulations, if and when adopted, could restrict our
ability to obtain, use, process or disseminate the individually identifiable
health information of our employees and the employees of our processing clients.
We process personally identifiable health data for many of our clients. In
connection with our services we and our clients will be required to comply with
HIPAA. We may be required to implement new technology and security features to
protect the privacy and integrity of such health data. Our compliance with these
new laws or regulations could require significant expenditures on our part.
Expenditures necessary for our own internal HIPAA compliance will not be
directly chargeable to our clients.

         While we believe that our compliance efforts undertaken on behalf of
our clients will result in an increase in our charges to such clients, we cannot
guarantee that such increases will

                                       10
13

occur. Furthermore, HIPAA subjects us in certain instances, as a service
provider, to liability and monetary penalties for failure to comply with HIPAA
when processing personally identifiable health data maintained by our clients.
If we fail to comply with HIPAA in connection with such processing services, we
could incur liability under these provisions.

OUR HIGH TURNOVER OF TECHNICALLY SKILLED EMPLOYEES REQUIRES THAT WE DEVOTE
SUBSTANTIAL RESOURCES TO ATTRACT AND RETAIN THEM. THE FAILURE TO ATTRACT AND
RETAIN TECHNICAL PERSONNEL AND SKILLED MANAGEMENT COULD HURT OUR ABILITY TO GROW
AND MANAGE OUR BUSINESS.

         Our success depends to a significant extent upon our ability to
attract, retain and motivate highly skilled and qualified personnel. If we fail
to attract, train, and retain sufficient numbers of these technically-skilled
people, our business, financial condition, and results of operations will be
materially and adversely affected. Competition for personnel is intense in the
information technology services industry, and recruiting and training personnel
requires substantial resources. We must continue to grow internally by hiring
and training technically-skilled people in order to perform services under our
existing contracts and new contracts that we will enter into. The people capable
of filling these positions are in great demand and recruiting and training these
personnel require substantial resources. Despite increasing our expenditures to
hire and retain a technically-skilled workforce, our business still experiences
significant turnover. Our success also depends on the skills, experience, and
performance of key members of our management team. The loss of any key employee
could have an adverse effect on our business, financial condition and results of
operations and prospects. Other than with Darwin Deason, we have not entered
into employment agreements with any of our key personnel, although we have
entered into severance agreements with certain of our executive officers and we
may in the future enter into employment agreements with our key personnel.

DARWIN DEASON HAS SUBSTANTIAL CONTROL OVER OUR COMPANY AND CAN AFFECT VIRTUALLY
ALL DECISIONS MADE BY OUR STOCKHOLDERS.

         Darwin Deason, our Chairman of the Board, beneficially owns 3,299,686
shares of Class B Common Stock and 2,504,174 shares of the Common Stock as of
March 1, 2001. Mr. Deason controls approximately 45% of the total voting power
of the Company (based on total shares of common stock outstanding as of March 1,
2001). As a result, Mr. Deason has the requisite voting power to significantly
affect virtually all decisions made by the Company and our stockholders,
including the power to block corporate actions such as an amendment to most
provisions of our certificate of incorporation. In addition, Mr. Deason may
significantly influence the election of directors and any other action requiring
shareholder approval. Mr. Deason serves as the one-person nominations committee
to our Board of Directors and thus recommends management's slate of directors to
be proposed by the Board to our shareholders. In the spring of 1999, Mr. Deason
was succeeded by Jeffrey A. Rich as Chief Executive Officer. Mr. Deason has an
employment contract including severance arrangements, which has an expiration
date of May 2004, and is annually renewable thereafter.

LEGAL PROCEEDINGS, INCLUDING A $17 MILLION JUDGMENT, COULD RESULT IN MATERIAL
CHARGES AGAINST EARNINGS.

                                       11
14

         On December 16, 1998, a state district court in Houston, Texas entered
final judgment against us in a lawsuit brought by twenty-one former employees of
Gibraltar Savings Association and/or First Texas Savings Association
(collectively, "GSA/FTSA"). The GSA/FTSA employees alleged that they were
entitled to the value of 401,541 shares of our stock pursuant to options issued
to the GSA/FTSA employees in 1988 in connection with a former data processing
services agreement between GSA/FTSA and us. The judgment against us was for
approximately $17,000,000, which includes attorneys' fees and pre-judgment
interest, but excludes additional attorneys' fees of approximately $850,000
which could be awarded in the event the plaintiffs are successful upon appeal
and final judgment. We continue to believe that we have meritorious defenses to
all or a substantial portion of the plaintiffs' claims. We filed our appeal of
the judgment on March 15, 1999 and are vigorously pursuing the appeal. The
plaintiffs also filed a notice of appeal and are pursuing their appeal. Should
the proceedings not be favorably resolved on appeal, we would be subject to a
charge equal to the amount of any final judgment, fees and interest awarded in
favor of the plaintiffs.

         Government contracts are subject to review and audit by various
governmental authorities in the normal course of our business. Cost audits have
been completed through fiscal 1998 for a majority of the federal government
business operations. In management's opinion, any such reviews and the results
of cost audits for subsequent fiscal years will not have a material effect on
our financial position or results of operations.

         We are subject to certain other legal proceedings, claims and disputes
which arise in the ordinary course of business. Although we cannot predict the
outcomes of these legal proceedings, management does not believe these actions,
in the aggregate, will have a material adverse effect on our financial position,
results of operations or liquidity.

PROVISIONS OF OUR CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE LAW COULD
DETER TAKEOVER ATTEMPTS THAT STOCKHOLDERS MAY THINK ARE IN THEIR BEST INTERESTS.

         Some provisions in our certificate of incorporation and bylaws could
also delay, defer, prevent or make more difficult a merger, tender offer, or
proxy contest involving our capital stock. Our stockholders might view
transactions such as these as being in their best interests because, for
example, a change of control might result in a price higher than the market
price for shares of the Common Stock. Among other things, these provisions:

         o        require an 80% vote of the stockholders to amend some
                  provisions of our certificate of incorporation;

         o        require an 80% vote of the stockholders to amend some
                  provisions of our bylaws;

         o        permit only our Chairman, President or a majority of the Board
                  of Directors to call stockholder meetings;

         o        authorize our Board of Directors to issue up to 3,000,000
                  shares of preferred stock in series with the terms of each
                  series to be fixed by our Board of Directors;

         o        authorize our Board of Directors to issue Class B Common
                  Stock, which shares are entitled to ten votes per share;

                                       12
15

         o        permit directors to be removed, with or without cause, only by
                  a vote of at least 80% of the combined voting power; and

         o        specify advance notice requirements for stockholder proposals
                  and director nominations to be considered at a meeting of
                  stockholders.

         In addition, with some exceptions, Section 203 of the Delaware General
Corporation Law restricts mergers and other business combinations between us and
any holder of 15% or more of our voting stock.

         We also have a stockholder rights plan. Under this plan, after the
occurrence of specified events, our stockholders will be able to buy stock from
us or our successor at reduced prices. These rights will not extend, however, to
persons participating in takeover attempts without the consent of our Board of
Directors. Accordingly, this plan could delay, defer or prevent a change of
control of our company.

         Further, we have entered into severance agreements with certain of our
executive officers, which may have the effect of discouraging an unsolicited
takeover proposal. Finally, Mr. Deason's ownership of approximately 45% of the
voting power of our capital stock could have the effect of delaying, deterring
or preventing a takeover of our company. See "Darwin Deason has substantial
control over our company and can affect virtually all decisions made by our
stockholders" for additional information about Mr. Deason's ownership.

INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS COULD REQUIRE US TO INCUR SUBSTANTIAL
COSTS TO DEFEND THE CLAIMS, CHANGE OUR SERVICES, PURCHASE NEW LICENSES OR
REDESIGN OUR USE OF CHALLENGED TECHNOLOGY.

         We and other companies in our industry rely heavily on the use of
intellectual property. We do not own the majority of the software that we use to
run our business; instead we license this software from a small number of
primary vendors. If these vendors assert claims that we or our clients are
infringing on their software or related intellectual property, we could incur
substantial costs to defend these claims.

         In addition, if any of our vendors' infringement claims are ultimately
successful, our vendors could require us (1) to cease selling or using products
or services that incorporate the challenged software or technology, (2) to
obtain a license or additional licenses from our vendors, or (3) to redesign our
products and services which rely on the challenged software or technology. We
are not currently involved in any material intellectual property litigation, but
could be in the future to protect our trade secrets or know-how, or to defend
ourselves or our clients against alleged infringement claims.

AVAILABILITY OF SIGNIFICANT AMOUNTS OF THE COMMON STOCK FOR SALE COULD CAUSE THE
MARKET PRICE OF THE COMMON STOCK TO DROP.

         There is a substantial number of shares of the Common Stock that may be
issued and subsequently sold under the Plans, upon exercise of employee stock
options, and upon conversion of our Class B Common Stock, our 4% convertible
subordinated notes and our 3.5%

                                       13
16

convertible subordinated notes. The sale or issuance of additional shares of the
Common Stock could adversely affect the prevailing market price of the Common
Stock.

WE MAY, IN THE FUTURE, BE EXPOSED TO RISKS RELATED TO INTERNATIONAL OPERATIONS
WHICH COULD INCREASE OUR COSTS AND HURT OUR BUSINESS.

         We currently have limited operations in many countries around the world
but may increase our international presence in the future. Risks that affect
international operations include:

         o        fluctuations in currency exchange rates;

         o        complicated licensing and work permit requirements;

         o        variations in the protection of intellectual property rights;

         o        restrictions on the ability to convert currency; and

         o        additional expenses and risks inherent in conducting
                  operations in geographically distant locations, with clients
                  speaking different languages and having different cultural
                  approaches to the conduct of business.

THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY, WHICH MAY RESULT IN
LOSSES FOR INVESTORS.

         The market price for the Common Stock has been and may continue to be
volatile. For example, during the 52-week period ended February 28, 2001, the
closing prices of the Common Stock as reported on the New York Stock Exchange
ranged from a high of $68.40 to a low of $31.31. We expect our stock price to be
subject to fluctuations as a result of a variety of factors, including factors
beyond our control. These factors include:

         o        actual or anticipated variations in our quarterly operating
                  results;

         o        announcements of technological innovations or new products or
                  services by us or our competitors;

         o        announcements relating to strategic relationships or
                  acquisitions;

         o        changes in financial estimates or other statements by
                  securities analysts;

         o        changes in general economic conditions;

         o        conditions or trends affecting the outsourcing industry; and

         o        changes in the economic performance and/or market valuations
                  of other information technology companies.

                                       14
17

         Because of this volatility, we may fail to meet the expectations of our
stockholders or of securities analysts at some time in the future, and our stock
price and therefore the price of our notes could decline as a result.

         In addition, the stock market has experienced significant price and
volume fluctuations that have particularly affected the trading prices of equity
securities of many high technology companies. These fluctuations have often been
unrelated or disproportionate to changes in the operating performance of these
companies. Any negative change in the public's perception of information
technology companies could depress our stock price regardless of our operating
results.

OTHER RISKS, UNKNOWN OR IMMATERIAL TODAY, MAY BECOME KNOWN OR MATERIAL IN THE
FUTURE.

         We have attempted to identify material risk factors currently affecting
our business and company. However, additional risks that we do not yet know of,
or that we currently think are immaterial, may occur or become material. These
risks could impair our business operations or adversely affect revenues or
profitability.

                                 USE OF PROCEEDS

         The Company will not receive any of the proceeds from the sale of the
Common Stock by the Selling Stockholders to the public pursuant to this

*        All Selling Stockholders will own less than 1% of the outstanding

(2)      Does not constitute a commitment to sell any or all of the stated
         number of shares of the Common Stock. The number of shares of the
         Common Stock offered shall be determined from time to time by each
         Selling Stockholder in his or her sole discretion.

                              PLAN OF DISTRIBUTION

         The Selling Stockholders may sell all or a portion of the shares of the
Common Stock from time to time under this Prospectus in one or more transactions
on the New York Stock Exchange, or other exchange, in a negotiated transaction
or in a combination of such methods of sale, at market prices prevailing at the
time of sale, at prices related to such prevailing market prices or at prices
otherwise negotiated. The Selling Stockholders may effect such transactions by
selling the shares of the Common Stock to or through broker-dealers, and such
broker-dealers may receive compensation in the form of underwriting discounts,
concessions or commissions from the Selling Stockholders and/or the purchasers
of the shares of the Common Stock for whom such broker-dealers may act as agent
(which compensation may be less than or in excess of customary commissions).

         The Selling Stockholders and any broker-dealers that participate in the
distribution of the shares of the Common Stock may be deemed to be
"underwriters" within the meaning of Section 2(11) of the Act, and any
commissions received by them and any profit on the resale of the shares of the
Common Stock sold by them may be deemed to be underwriting discounts and
commissions under the Act. All selling and other expenses incurred by the
Selling Stockholders will be borne by the Selling Stockholders.

         In addition to any shares of the Common Stock sold hereunder, the
Selling Stockholders may, at the same time, sell any other shares of the Common
Stock, owned by them in compliance with all of the requirements of Rule 144,
regardless of whether such shares of the Common Stock are covered by this
Prospectus.

         There is no assurance that the Selling Stockholders will sell all or
any portion of the shares of the Common Stock covered by this Prospectus.

         The Company will pay all expenses related to registering the shares of
the Common Stock covered by this Prospectus and will not receive any proceeds
from sales of any such shares of the Common Stock by the Selling Stockholders to
the public.

                                  LEGAL MATTERS

         The validity of the Common Stock issuable under the Plans has been
passed upon for us by Jackson Walker L.L.P., Dallas, Texas.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Delaware General Corporation Law (the "DGCL") authorizes Delaware
corporations to limit the liability of directors and officers to the corporation
or its stockholders for money damages, except for (a) breaches of a director's
duty of loyalty to the corporation or its stockholders; (b) acts or omissions
not in good faith or involving intentional misconduct or knowing violations of
the law; (c) the payment of unlawful dividends or unlawful stock repurchases or
redemptions; or (d) transactions in which the director received an improper
personal benefit. The DGCL, unless limited by the corporation's charter,
provides that indemnification is mandatory to the extent that a director,
officer, employee or agent, acting in good faith, and in a manner that he or she
reasonably believes to be in, or not opposed to, the best interests of the
corporation, or with respect to any criminal action or proceeding, there was no
reason to believe that his or her conduct was unlawful, or has been successful
on the merits or otherwise in the defense of any proceeding covered by the
indemnification statute. The DGCL generally permits indemnification for expenses
incurred in the defense or settlement of derivative or third party actions,
provided that there is a determination by a majority vote of the directors who
are not parties to the action even though less than a quorum, or by a committee
of directors designated by a majority vote of the directors, even though less
than a quorum, or if such directors so direct, by independent legal counsel in a
written opinion, or by the stockholders, that the person seeking indemnification
acted in good faith and in a manner reasonably believed to be in, or not opposed
to, the best interests of the corporation, or in a criminal proceeding that the
person had no reason to believe that his or her conduct to be unlawful. Without
court approval, however, no indemnification may be made in respect of any
derivative action in which such person is adjudged liable. The DGCL states that
the indemnification provided by the statute shall not be deemed exclusive of any
other rights under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

         Article Ninth of the Certificate of Incorporation of the Company limits
the liability of directors and officers to the fullest extent permitted by the
DGCL. Article Ninth of the Charter of the Company also authorizes the Company to
enter into contracts, adopt bylaws or resolutions to provide for the
indemnification of the Company's directors and officers. Section 33 of the
23

Company's bylaws provides for the indemnification of the Company's directors and
officers to the fullest extent permitted by the DGCL. In addition, the Company's
directors and officers are covered by certain insurance policies maintained by
the Company.

         Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers or persons controlling the Company pursuant to
the foregoing provisions, the Company has been informed that in the opinion of
the Commission, such indemnification is against public policy as expressed in
the Act and is therefore unenforceable.

ITEM 9.           UNDERTAKINGS.

         (a)      The Company hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:
24

                           (i) To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in this Registration
Statement;

                  (2) That, for the purpose of determining any liability under
the Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Company hereby undertakes that, for purposes of determining any
liability under the Act, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
filing of the Plans' annual reports pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
25

                                   SIGNATURES

         Pursuant to the requirements of the Act, the Company certifies that it
has reasonable grounds to believe that it meets all of the requirements for
filing on Form S-8 and has duly caused this Registration Statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of
Dallas, State of Texas on the 30th day of May, 2001.
