                       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.

RECENT DEVELOPMENTS

     During December 2000, we acquired Business Resources Corporation ("BRC"), a
subsidiary of Tyler Technologies, Inc. for approximately $70 million in cash,
which was funded by borrowings under our existing credit facility. BRC is a
provider of outsourced records management, document workflow, imaging systems
and services to state and local governments. BRC also provides real estate title
plant services to title companies. The acquisition was accounted for under the
purchase method of accounting, and BRC's results have been included in our
consolidated financial statements from the effective date of the acquisition.

                                  RISK FACTORS

     You should carefully consider the following risks before making an
investment decision. You should also refer to the other information set forth in
this prospectus and incorporated by reference in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results could vary significantly from the results
discussed in the forward-looking statements. Some 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 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. See "-- 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" for
a description of related risks. 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

                                        2
   5

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 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:

     - higher acquisition prices due to increased competition for acquisitions;

     - fewer suitable acquisition candidates at acceptable prices;

     - insufficient capital resources for acquisitions;

     - inability to successfully integrate or operate acquired companies;

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

     - 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.
This trend could adversely affect our business and financial results. Future

                                        3
   6

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.

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.

                                        4

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.

     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 Healthcare 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 December 2000, HHS
published its final health data privacy regulations which became effective in
April 2001 and must be complied with by April 14, 2003. These regulations
restrict the use and disclosure of personally identifiable health information
without the prior informed consent of the patient. HHS has not yet issued final
rules on most of the other provisions under HIPAA and has yet to issue proposed
rules on other

                                        5
   8

provisions. The final rules, if and when issued, may differ from the proposed
rules. We cannot predict the potential impact of the final rules or the rules
that have not yet been proposed. In addition, other federal or state privacy
legislation may be enacted at any time.

     These laws or regulations, when adopted, could restrict our ability to
obtain, use, process or disseminate the personally 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 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 Class A Common Stock as
of March 1, 2001. Mr. Deason controls approximately 45% of the total voting
power of ACS (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 ACS 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.

     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 our
Class A Common Stock. Among other things, these provisions:

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

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

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

     - 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;

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

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

     - 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

                                        7
   10

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 CLASS A COMMON STOCK FOR SALE COULD CAUSE
THE MARKET PRICE OF OUR CLASS A COMMON STOCK TO DROP.

     There is a substantial number of shares of our Class A Common Stock that
may be issued and subsequently sold upon exercise of employee stock options, and
upon conversion of our Class B Common Stock, our 4% convertible subordinated
notes and the notes covered by this prospectus. The sale or issuance of
additional shares of Class A Common Stock following this offering could
adversely affect the prevailing market price of the Class A Common Stock. See
"Description of Capital Stock" for a description of these shares.

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:

     - fluctuations in currency exchange rates;

     - complicated licensing and work permit requirements;

     - variations in the protection of intellectual property rights;

     - restrictions on the ability to convert currency; and

     - 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 AND THEREFORE THE PRICE OF OUR NOTES MAY FLUCTUATE
SIGNIFICANTLY, WHICH MAY RESULT IN LOSSES FOR INVESTORS.

     The market price for our Class A Common Stock has been and may continue to
be volatile. For example, during the 52-week period ended April 30, 2001, the
closing prices of our Class A Common Stock as reported on the New York Stock
Exchange ranged from a high of $72.00 to a low of $32.56. We

                                        8
   11

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:

     - actual or anticipated variations in our quarterly operating results;

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

     - announcements relating to strategic relationships or acquisitions;

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

     - changes in general economic conditions;

     - conditions or trends affecting the outsourcing industry; and

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

     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.

THE NOTES RANK BELOW OUR SENIOR DEBT, AND WE MAY BE UNABLE TO REPAY OUR
OBLIGATIONS UNDER THE NOTES.

     The notes are unsecured and subordinated in right of payment to all of our
senior debt. Because the notes are subordinate to our senior debt, if we
experience:

     - a bankruptcy, liquidation or reorganization;

     - an acceleration of the notes due to an event of default under the
       Indenture; or

     - other specified events;

we are permitted to make payments on the notes only after we have satisfied all
of our senior debt obligations. Therefore, we may not have sufficient assets
remaining to pay amounts due on any or all of the notes. In addition, the notes
effectively will be subordinate to all liabilities, including trade payables, of
our subsidiaries and any subsidiaries that we may in the future acquire or
establish. Consequently, our right to receive assets of any subsidiaries upon
their liquidation or reorganization, and the rights of the holders of the notes
to share in those assets, would be subordinate to the claims of the
subsidiaries' creditors.

     The notes are our obligations exclusively. The Indenture for the notes does
not limit our ability, or that of any of our presently existing or future
subsidiaries, to incur senior debt, other indebtedness and other liabilities. We
may have difficulty paying what we owe under the notes if we, or any of our
subsidiaries, incur additional indebtedness or other liabilities. As of March
31, 2001, we had senior debt outstanding of approximately $167 million, and our
subsidiaries had approximately $270 million of outstanding liabilities,
excluding intercompany liabilities. From time to time we and our subsidiaries
may incur additional indebtedness, including senior debt, which could adversely
affect our ability to pay our obligations under the notes.

WE MAY BE UNABLE TO REPAY OR REPURCHASE THE NOTES.

     At maturity, the entire outstanding principal amount of the notes will
become due and payable. In addition, if we experience a change in control, as
defined in "Description of the Notes -- Repurchase at Option of Holders Upon a
Change in Control," each holder of the notes may require us to repurchase all or
a portion of that holder's notes. At maturity or if a change in control occurs,
we may not have sufficient funds or may be unable to arrange for additional
financing to pay the principal amount or repurchase price

                                        9
   12

due. Under the terms of the Indenture for the notes, we may elect, if we meet
certain conditions, to pay the repurchase price with shares of Class A Common
Stock. Any future borrowing arrangements or agreements relating to senior debt
to which we become a party may contain restrictions on, or prohibitions against,
our repayments or repurchases of the notes. If the maturity date or change in
control occurs at a time when our other arrangements prohibit us from repaying
or repurchasing the notes, we could try to obtain the consent of the lenders
under those arrangements, or we could attempt to refinance the borrowings that
contain the restrictions. If we do not obtain the necessary consents or
refinance these borrowings, we will be unable to repay or repurchase the notes.
In that case, our failure to repurchase any tendered notes or repay the notes
due upon maturity would constitute an event of default under the Indenture. Any
such default, in turn, may cause a default under the terms of our senior debt.
As a result, in those circumstances, the subordination provisions of the
Indenture would, absent a waiver, prohibit any repayment or repurchase of the
notes until we pay the senior debt in full.

THERE MAY BE NO PUBLIC MARKET FOR THE NOTES, OR IF THERE IS ONE, WE CANNOT
ENSURE THAT IT WILL CONTINUE FOR ANY PERIOD OF TIME.

     Prior to offering the notes, there was no trading market for the notes.
Although the initial purchasers advised us that they currently intend to make a
market in the notes, the initial purchasers are not obligated to do so and may
discontinue their market-making activities at any time without notice.
Consequently, we cannot ensure that any market for the notes will develop, or if
one does develop, that it will continue for any period of time. If an active
market for the notes fails to develop or continue, this failure could harm the
trading price of the notes. We do not intend to apply for listing of the notes
on any securities exchange or any automated quotation system.

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.

     All of the notes and the shares of our Class A Common Stock issuable upon
conversion of the notes are being sold by the selling securityholders or by
their pledgees, donees, transferees or other successors in interest. We will not
receive any proceeds from the sale of the notes or the shares of our Class A
Common Stock issuable upon conversion of the notes.

                              DESCRIPTION OF NOTES

     We issued the notes under a document called the "Indenture." The Indenture
is a contract between us and U.S. Trust Company of Texas, N.A., as Trustee.
Because this section is a summary, it does not describe every aspect of the
notes and the Indenture that may be important to you, and is subject to and
qualified in its entirety by reference to all of the provisions of the
Indenture. In this section, we use capitalized words to signify defined terms
that have been given special meaning in the Indenture. We describe the meaning
of only the more important terms. You should read the Indenture itself for a
full description of the terms of the notes. Wherever we refer to particular
defined terms, those defined terms are incorporated by reference here. In this
section, references to "ACS," "we," "our" or "us" refer solely to Affiliated
Computer Services, Inc. and not its subsidiaries.

GENERAL

     The notes are general, unsecured obligations of ACS. The notes are
subordinated, which means that they rank behind certain of our indebtedness as
described below. The notes are limited to $316,990,000 aggregate principal
amount. We are required to repay the principal amount of the notes in full on
February 15, 2006. The notes bear interest at the rate of 3.50% per annum.
Interest is computed on the basis of a 360-day year of twelve thirty-day months.
We will pay interest on the notes on February 15 and August 15 of each year,
commencing on August 15, 2001.

     A holder of notes may convert the notes into shares of our Class A Common
Stock initially at the conversion rate of 11.5117 shares per $1,000 in principal
amount of the notes at any time before the close of business on February 15,
2006, unless the notes have been previously redeemed or repurchased. The
conversion rate may be adjusted as described below.

     We may redeem the notes at our option at any time on or after February 18,
2004, in whole or in part, at the redemption prices set forth below under
"-- Optional Redemption by ACS," plus accrued and unpaid interest to the
redemption date. If there is a Change in Control of ACS, you may have the right
to require us to repurchase your notes as described below under "-- Repurchase
at Option of Holders Upon a Change in Control."

FORM, DENOMINATION, TRANSFER, EXCHANGE AND BOOK-ENTRY PROCEDURES

     The notes are issued:

     - only in fully registered form,

     - without interest coupons, and

     - in denominations of $1,000 and greater multiples.

     The notes are evidenced by one or more global notes which were deposited
with the Trustee as custodian for The Depository Trust Company ("DTC") and
registered in the name of Cede & Co. ("Cede"), as nominee of DTC. The global
notes and any notes issued in exchange for any global note are subject to
restrictions on transfer and will bear the legend regarding those restrictions
set forth under "Notice to Investors." Except as set forth below, record
ownership of any global note may be transferred, in whole or in part, only to
another nominee of DTC or to a successor of DTC or its nominee.

     The global notes will not be registered in the name of any person, or
exchanged for notes that are registered in the name of any person, other than
DTC or its nominee unless either of the following occurs:

     - DTC notifies us that it is unwilling, unable or no longer qualified to
       continue acting as the depositary for the global notes; or

     - an Event of Default with respect to the notes represented by the global
       notes has occurred and is continuing.

In those circumstances, DTC will determine in whose names any securities issued
in exchange for the global notes will be registered.

                                        11
   14

     DTC or its nominee will be considered the sole owner and holder of the
global notes for all purposes, and as a result:

     - a holder of notes cannot get notes registered in its name if they are
       represented by a global note;

     - a holder of notes cannot receive certificated (physical) notes in
       exchange for its beneficial interest in the global notes;

     - a holder of notes will not be considered to be the owner or holder of a
       global note or any note it represents for any purpose; and

     - all payments on the global notes will be made to DTC or its nominee.

     The laws of some jurisdictions require that certain kinds of purchasers
(for example, certain insurance companies) can only own securities in definitive
(certificated) form. These laws may limit your ability to transfer your
beneficial interests in a global note to these types of purchasers.

     Only institutions (such as a securities broker or dealer) that have
accounts with DTC or its nominee (called "participants") and persons that may
hold beneficial interests through participants can own a beneficial interest in
a global note. The only place where the ownership of beneficial interests in a
global note will appear and the only way the transfer of those interests can be
made will be on the records kept by DTC (for their participants' interests) and
the records kept by those participants (for interests of persons held by
participants on their behalf).

     Secondary trading in bonds and notes of corporate issuers is generally
settled in clearinghouse (that is, next-day) funds. In contrast, beneficial
interests in a global note usually trade in DTC's same-day funds settlement
system, and settle in immediately available funds. We make no representations as
to the effect that settlement in immediately available funds will have on
trading activity in those beneficial interests.

     We will make cash payments of interest on and principal of and the
redemption or repurchase price of the global notes, as well as any payment of
Liquidated Damages (as described below under "-- Registration Rights"), in
respect of the notes, to Cede, the nominee for DTC, as the registered owner of
the global notes. We will make these payments by wire transfer of immediately
available funds on each payment date.

     We have been informed that DTC's practice is to credit participants'
accounts on the payment date with payments in amounts proportionate to their
respective beneficial interests in the notes represented by a global note as
shown on DTC's records, unless DTC has reason to believe that it will not
receive payment on that payment date. Payments by participants to owners of
beneficial interests in notes represented by a global note held through
participants will be the responsibility of those participants, as is now the
case with securities held for the account of customers registered in "street
name."

     We will send any redemption notices to Cede. We understand that if less
than all the notes are being redeemed, DTC's practice is to determine by lot the
amount of the holdings of each participant to be redeemed.

     We also understand that neither DTC nor Cede will consent or vote with
respect to the notes. We have been advised that under its usual procedures, DTC
will mail an "omnibus proxy" to us as soon as possible after the record date.
The omnibus proxy assigns Cede's consenting or voting rights to those
participants to whose accounts the notes are credited on the record date
identified in a listing attached to the omnibus proxy.

     Because DTC can only act on behalf of participants, who in turn act on
behalf of indirect participants, the ability of a person having a beneficial
interest in the principal amount represented by a global note to pledge the
interest to persons or entities that do not participate in the DTC book-entry
system, or otherwise take actions in respect of that interest, may be affected
by the lack of a physical certificate evidencing its interest.

     DTC has advised us that it will take any action permitted to be taken by a
holder of notes (including the presentation of notes for exchange) only at the
direction of one or more participants to whose account with DTC interests in the
global notes are credited and only in respect of such portion of the principal

                                        12
   15

amount of the notes represented by the global notes as to which such participant
or participants has or have given such direction.

     DTC has also advised us as follows:

     - DTC is a limited purpose trust company organized under the laws of the
       State of New York,

     - a member of the Federal Reserve System,

     - a "clearing corporation" within the meaning of the Uniform Commercial
       Code, as amended, and

     - a "clearing agency" registered pursuant to the provisions of Section 17A
       of the Exchange Act.

     DTC was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants. Participants
include securities brokers and dealers, banks, trust companies and clearing
corporations and may include certain other organizations. Certain of such
participants (or their representatives), together with other entities, own DTC.
Indirect access to the DTC system is available to other entities such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

     The policies and procedures of DTC, which may change periodically, will
apply to payments, transfers, exchanges and other matters relating to beneficial
interests in the global notes. We and the Trustee have no responsibility or
liability for any aspect of DTC's or any participants' records relating to
beneficial interests in the global notes, including for payments made on the
global notes, and we and the Trustee are not responsible for maintaining,
supervising or reviewing any of those records.

CONVERSION RIGHTS

     A holder of notes may, at its option, convert any portion of the principal
amount of any note that is an integral multiple of $1,000 into shares of our
Class A Common Stock at any time prior to the close of business on the maturity
date, unless the notes have been previously redeemed or repurchased, at a
conversion rate of 11.5117 shares of Class A Common Stock per $1,000 principal
amount of notes. The conversion rate is equivalent to a conversion price of
approximately $86.87. The right of a holder of notes to convert a note called
for redemption or delivered for repurchase will terminate at the close of
business on the business day prior to the redemption date or repurchase date for
that note, unless we default in making the payment due upon redemption or
repurchase.

     A holder of notes may convert all or part of any note by delivering the
note at the Corporate Trust Office of the Trustee in the Borough of Manhattan,
the City of New York, accompanied by a duly signed and completed notice of
conversion, a copy of which may be obtained by the Trustee. The conversion date
will be the date on which the note and the duly signed and completed notice of
conversion are so delivered.

     As promptly as practicable on or after the conversion date, we will issue
and deliver to the Trustee a certificate or certificates for the number of full
shares of our Class A Common Stock issuable upon conversion, together with
payment in lieu of any fraction of a share. The certificate will then be sent by
the Trustee to the conversion agent for delivery to the holder. The shares of
our Class A Common Stock issuable upon conversion of the notes will be fully
paid and nonassessable and will rank equally with the other shares of our Class
A Common Stock.

     If a holder of notes surrenders a note for conversion on a date that is not
an Interest Payment Date, the holder will not be entitled to receive any
interest for the period from the next preceding Interest Payment Date to the
conversion date, except as described below in this paragraph. Any note
surrendered for conversion during the period from the close of business on any
Regular Record Date to the opening of business on the next succeeding Interest
Payment Date (except notes (or portions thereof) called for redemption on a
redemption date or to be repurchased on the repurchase date for which the right
to convert would terminate during such period) must be accompanied by payment of
an amount equal to the interest payable on such Interest Payment Date on the
principal amount of notes being surrendered for conversion. In the case of any
note which has been converted after any Regular Record Date (as defined

                                        13
   16

below under "-- Payment and Conversion") but before the next succeeding Interest
Payment Date, interest payable on such Interest Payment Date shall be payable on
such Interest Payment Date notwithstanding such conversion, and such interest
shall be paid to the holder of the note on such Regular Record Date.

     No other payment or adjustment for interest, or for any dividends in
respect of our Class A Common Stock, will be made upon conversion. Holders of
our Class A Common Stock issued upon conversion will not be entitled to receive
any dividends payable to holders of our Class A Common Stock as of any record
time or date before the close of business on the conversion date. We will not
issue fractional shares upon conversion. Instead, we will pay cash based on the
market price of our Class A Common Stock at the close of business on the
conversion date.

     A holder of notes will not be required to pay any taxes or duties relating
to the issue or delivery of our Class A Common Stock on conversion but will be
required to pay any tax or duty relating to any transfer involved in the issue
or delivery of our Class A Common Stock in a name other than that of the holder.
Certificates representing shares of our Class A Common Stock will not be issued
or delivered unless all taxes and duties, if any, payable by you have been paid.

     The conversion rate will be subject to adjustment for, among other things:

     - dividends (and other distributions) payable in our Class A Common Stock
       on shares of our capital stock;

     - the issuance to all holders of our Class A Common Stock of rights,
       options or warrants entitling them to subscribe for or purchase our Class
       A Common Stock at less than the then Current Market Price of such Class A
       Common Stock (determined as provided in the Indenture) as of the record
       date for shareholders entitled to receive such rights, options or
       warrants;

     - subdivisions, combinations and reclassifications of our Class A Common
       Stock;

     - distributions to all holders of our Class A Common Stock of evidences of
       indebtedness of ACS, shares of capital stock, cash or assets (including
       securities, but excluding those dividends, rights, options, warrants and
       distributions referred to above, dividends and distributions paid
       exclusively in cash and distributions upon mergers or consolidations as
       discussed below);

     - distributions consisting exclusively of cash (excluding any cash portion
       of distributions referred to in the immediately preceding clause, or cash
       distributed upon a merger or consolidation as discussed below) to all
       holders of our Class A Common Stock in an aggregate amount that, combined
       together with (1) other such all-cash distributions made within the
       preceding 12 month period in respect of which no adjustment has been made
       and (2) any cash and the fair market value of other consideration payable
       in connection with any tender offer by us or any of our subsidiaries for
       our Class A Common Stock concluded within the preceding 12 month period
       in respect of which no adjustment has been made, exceeds 10% of our
       market capitalization (being the product of the Current Market Price per
       share of the Class A Common Stock on the record date for such
       distribution and the number of shares of Class A Common Stock then
       outstanding); and

     - the successful completion of a tender offer made by us or any of our
       subsidiaries for our Class A Common Stock which involves an aggregate
       consideration that, together with any cash and other consideration
       payable in a tender offer by us or any of our subsidiaries for our Class
       A Common Stock expiring within the 12 month period preceding the
       expiration of such tender offer in respect of which no adjustment has
       been made, exceeds 10% of our market capitalization on the expiration of
       such tender offer.

     We reserve the right to effect such increases in the conversion rate in
addition to those required by the foregoing provisions as we consider to be
advisable in order that any event treated for United States federal income tax
purposes as a dividend of stock or stock rights will not be taxable to the
recipients. We will not be required to make any adjustment to the conversion
rate until the cumulative adjustments amount to 1.0% or more of the conversion
rate. We will compute all adjustments to the conversion rate and will give
notice by mail to holders of the registered notes of any adjustments.

                                        14
   17

     In case of any consolidation or merger of ACS with or into another entity
or any merger of another entity into ACS (other than a merger which does not
result in any reclassification, conversion, exchange or cancellation of our
Class A Common Stock), or in case of any sale or transfer of all or
substantially all of our assets, each note then outstanding will become
convertible only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer by a holder of the
number of shares of Class A Common Stock into which the notes were convertible
immediately prior to the consolidation or merger or sale or transfer.

     We may increase the conversion rate for any period of at least 20 days,
upon at least 15 days' notice, if our Board of Directors determines that the
increase would be in our best interest. The Board of Directors' determination in
this regard will be conclusive. We will give holders of notes at least 15 days'
notice of such an increase in the conversion rate. Any increase, however, will
not be taken into account for purposes of determining whether the closing price
of our Class A Common Stock exceeds the conversion price by 105% in connection
with an event which otherwise would be a Change in Control as defined below.

     We may also increase the conversion rate for the remaining term of the
notes or any shorter period in order to avoid or diminish any income tax to any
holders of shares of Class A Common Stock resulting from any dividend or
distribution of stock or issuance of rights or warrants to purchase or subscribe
for stock or from any event treated as such for income tax purposes. If at any
time we make a distribution of property to our stockholders that would be
taxable to such stockholders as a dividend for United States federal income tax
purposes, such as distributions of evidences of indebtedness or assets of ACS,
but generally not stock dividends on Class A Common Stock or rights to subscribe
for Class A Common Stock, and, pursuant to the adjustment provisions of the
Indenture, the conversion price (as defined in the Indenture) of the notes is
reduced, that reduction may be deemed for United States federal income tax
purposes to be the payment of a taxable dividend to holders of notes. See
"Summary of Certain United States Federal Income Tax Considerations
 -- Constructive Dividends on Notes."

SUBORDINATION

     The notes are subordinated and, as a result, the payment of the principal,
any premium and interest (including Liquidated Damages) on the notes, including
amounts payable on any redemption or repurchase, will be subordinated to the
prior payment in full, in cash or other payment satisfactory to holders of
Senior Indebtedness, of all of our Senior Indebtedness. The notes are also
effectively subordinated to any debt or other liabilities of our subsidiaries.
On March 31, 2001, we had approximately $167 million outstanding Senior
Indebtedness and the aggregate amount of liabilities of our subsidiaries was
approximately $270 million, excluding intercompany liabilities.

     "Senior Indebtedness" is defined in the Indenture to mean: the principal of
(and premium, if any) and interest (including all interest accruing subsequent
to the commencement of any bankruptcy or similar proceeding, whether or not a
claim for post-petition interest is allowable as a claim in any such proceeding)
on, and all fees and other amounts payable in connection with, the following,
whether absolute or contingent, secured or unsecured, due or to become due,
outstanding on the date of the Indenture or thereafter created, incurred or
assumed:

     - our indebtedness evidenced by a credit or loan agreement, note, bond,
       debenture or other written obligation;

     - all of our obligations for money borrowed;

     - all of our obligations evidenced by a note or similar instrument given in
       connection with the acquisition of any businesses, properties or assets
       of any kind;

     - our obligations (1) as lessee under leases required to be capitalized on
       the balance sheet of the lessee under generally accepted accounting
       principles and (2) as lessee under other leases for facilities, capital
       equipment or related assets, whether or not capitalized, entered into or
       leased for financing purposes;

                                        15
   18

     - all of our obligations under interest rate and currency swaps, caps,
       floors, collars, hedge agreements, forward contracts or similar
       agreements or arrangements;

     - all of our obligations with respect to letters of credit, bankers'
       acceptances and similar facilities (including reimbursement obligations
       with respect to the foregoing);

     - all of our obligations issued or assumed as the deferred purchase price
       of property or services (but excluding trade accounts payable and accrued
       liabilities arising in the ordinary course of business);

     - all obligations of the type referred to in the above clauses of another
       person and all dividends of another person, the payment of which, in
       either case, we have assumed or guaranteed, or for which we are
       responsible or liable, directly or indirectly, jointly or severally, as
       obligor, guarantor or otherwise, or which are secured by a lien on our
       property; and

     - renewals, extensions, modifications, replacements, restatements and
       refundings of, or any indebtedness or obligation issued in exchange for,
       any such indebtedness or obligation described in the above clauses of
       this definition.

     Senior Indebtedness will not include the notes or any other indebtedness or
obligation if its terms or the terms of the instrument under which or pursuant
to which it is issued expressly provide that it is not superior in right of
payment to the notes.

     We may not make any payment on account of principal, premium or interest
(including Liquidated Damages, if any of the notes or any shares of Class A
Common Stock issued on conversion therein), or redemption or repurchase of the
notes, if either of the following occurs:

     - we default in our obligations to pay principal, premium, interest or
       other amounts on our Senior Indebtedness, including a default under any
       redemption or repurchase obligation, and the default continues beyond any
       grace period that we may have to make those payments; or

     - any other default occurs and is continuing on any Designated Senior
       Indebtedness (as defined below) and (1) the default permits the holders
       of the Designated Senior Indebtedness to accelerate its maturity and (2)
       the Trustee has received a notice (a "Payment Blockage Notice") of the
       default from ACS, the holder of such debt or such other person permitted
       to give such notice under the Indenture.

     If payments of the notes have been blocked by a payment default on Senior
Indebtedness, payments on the notes may resume when the payment default has been
cured or waived or ceases to exist. If payments on the notes have been blocked
by a nonpayment default, payments on the notes may resume on the earlier of (1)
the date the nonpayment default is cured or waived or ceases to exist or (2) 179
days after the Payment Blockage Notice is received if the maturity of the
Designated Senior Indebtedness has not been accelerated.

     No nonpayment default that existed on the day a Payment Blockage Notice was
delivered to the Trustee can be used as the basis for any subsequent Payment
Blockage Notice. In addition, once a holder of Designated Senior Indebtedness
has blocked payment on the notes by giving a Payment Blockage Notice, no new
period of payment blockage can be commenced pursuant to a subsequent Payment
Blockage Notice until both of the following are satisfied:

     - 365 days have elapsed since the effectiveness of the immediately prior
       Payment Blockage Notice; and

     - all scheduled payments of principal, any premium and interest with
       respect to the notes that have come due have been paid in full in cash.

     "Designated Senior Indebtedness" means our obligations under any particular
Senior Indebtedness in which the instrument creating or evidencing the same or
the assumption or guarantee thereof (or related agreements or documents to which
we are a party), whether or not executed contemporaneously with the incurrence
of such Senior Indebtedness, expressly provides that such indebtedness shall be
"Designated Senior Indebtedness" for purposes of the Indenture. The instrument,
agreement or other document

                                        16
   19

evidencing any Designated Senior Indebtedness may place limitations and
conditions on the right of such Senior Indebtedness to exercise the rights of
Designated Senior Indebtedness.

     In addition, upon any acceleration of the principal due on the notes as a
result of an Event of Default or upon any payment or distribution of our assets
to creditors upon any dissolution, winding up, liquidation or reorganization,
whether voluntary or involuntary, marshaling of assets, assignment for the
benefit of creditors, or in bankruptcy, insolvency, receivership or other
similar proceedings, all principal, premium, if any, interest and other amounts
due on all Senior Indebtedness must be paid in full before you are entitled to
receive any payment. By reason of such subordination, in the event of
insolvency, our creditors who are holders of Senior Indebtedness are likely to
recover more, ratably, than you are, and you will be likely to experience a
reduction or elimination of payments on the notes.

     Further, the notes will be "structurally subordinated" to all indebtedness
and other liabilities, including trade payables and lease obligations, of our
subsidiaries. This occurs because any right of ACS to receive any assets of our
subsidiaries upon their liquidation or reorganization, and the right of the
holders of the notes to participate in those assets, will be effectively
subordinated to the claims of that subsidiary's creditors, including trade
creditors, except to the extent that ACS itself is recognized as a creditor of
such subsidiary, in which case the claims of ACS would still be subordinate to
any security interest in the assets of the subsidiary and any indebtedness of
the subsidiary senior to that held by ACS.

     The Indenture does not limit our ability to incur Senior Indebtedness or
our ability or the ability of our subsidiaries to incur any other indebtedness.

OPTIONAL REDEMPTION BY ACS

     On or after February 18, 2004, we may redeem the notes, in whole or in
part, at the prices set forth below. If we elect to redeem all or part of the
notes, we will give at least 30 but no more than 60 days notice to you. Promptly
after giving such notice, we will make a public announcement thereof by release
made to Reuters Economic Services and Bloomberg Business News.

     The redemption price, expressed as a percentage of principal amount, is as
follows for the periods set forth below:



                                                             REDEMPTION
YEAR                                                           PRICE
----                                                         ----------
                                                          
February 18, 2004 to February 14, 2005.....................   101.40%
February 15, 2005 to February 14, 2006.....................   100.70%


and thereafter is equal to 100% of the principal amount, in each case together
with accrued interest to the date of redemption.

     No sinking fund is provided for the notes, which means that the Indenture
does not require us to redeem or retire the notes periodically.

     We may, to the extent permitted by applicable law, at any time purchase
notes in the open market, by tender at any price or by private agreement. Any
note that we purchase may, to the extent permitted by applicable law and subject
to restrictions contained in the purchase agreement with the initial purchasers,
be re-issued or resold or may, at our option, be surrendered to the Trustee for
cancellation. Any notes surrendered for cancellation may not be re-issued or
resold and will be canceled promptly.

PAYMENT AND CONVERSION

     We will make all payments of principal and interest on registered notes by
U.S. dollar check drawn on an account maintained at a bank in The City of New
York. If a holder of notes holds registered notes with a face value greater than
$2,000,000, at the request of the holder we will make payments of principal or
interest to the holder by wire transfer to an account maintained by the holder
at a bank in The City of New York. Payment of any interest on the notes will be
made to the person in whose name a note, or any predecessor note, is registered
at the close of business on the February 1 or the August 1 (whether or not a
business day) immediately preceding the relevant Interest Payment Date (a
"Regular Record Date"). If a holder of notes holds registered notes with a face
value in excess of $2,000,000 and the holder would like

                                        17
   20

to receive payments by wire transfer, the holder will be required to provide the
Trustee with wire transfer instructions at least 15 days prior to the relevant
payment date.

     Payments on any global note registered in the name of DTC or its nominee
will be payable by the Trustee to DTC or its nominee in its capacity as the
registered holder under the Indenture. Under the terms of the Indenture, we and
the Trustee will treat the persons in whose names the notes, including any
global note, are registered as the owners for the purpose of receiving payments
and for all other purposes. Consequently, neither we, the Trustee nor any of our
agents or the Trustee's agents has or will have any responsibility or liability
for (1) any aspect of DTC's records or any participant's or indirect
participant's records relating to or payments made on account of beneficial
ownership interests in a global note, or for maintaining, supervising or
reviewing any of DTC's records or any participant's or indirect participant's
records relating to the beneficial ownership interests in a global note, or (2)
any other matter relating to the actions and practices of DTC or any of its
participants or indirect participants.

     We will not be required to make any payment on the notes due on any day
which is not a business day until the next succeeding business day. The payment
made on the next succeeding business day will be treated as though it were paid
on the original due date and no interest will accrue on the payment for the
additional period of time.

     Notes may be surrendered for conversion at the Corporate Trust Office of
the Trustee in the Borough of Manhattan, The City of New York. Notes surrendered
for conversion must be accompanied by appropriate notices and any payments in
respect of interest or taxes, as applicable, as described above under
"-- Conversion Rights."

     We have initially appointed the Trustee as paying agent and conversion
agent. We may terminate the appointment of any paying agent or conversion agent
and appoint additional or other paying agents and conversion agents. However,
until the notes have been delivered to the Trustee for cancellation, or moneys
sufficient to pay the principal of, premium, if any, and interest on the notes
have been made available for payment and either paid or returned to us as
provided in the Indenture, the Trustee will maintain an office or agency in the
Borough of Manhattan, The City of New York for surrender of notes for
conversion. Notice of any termination or appointment and of any change in the
office through which any paying agent or conversion agent will act will be given
in accordance with "-- Notices" below.

     All moneys deposited with the Trustee or any paying agent, or then held by
us, in trust for the payment of principal of, premium, if any, or interest on
any notes which remain unclaimed at the end of two years after the payment has
become due and payable will be repaid to us, and a holder of notes will then
look only to us for payment.

REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE IN CONTROL

     If a Change in Control as defined below occurs, a holder of notes will have
the right, at its option, to require us to repurchase all of its notes not
previously called for redemption, or any portion of the principal amount
thereof, that is equal to $1,000 or an integral multiple of $1,000. The price we
are required to pay is 100% of the principal amount of the notes to be
repurchased plus interest accrued to the repurchase date.

     At our option, instead of paying the repurchase price in cash, we may pay
the repurchase price in our Class A Common Stock valued at 95% of the average of
the closing prices of our Class A Common Stock for the five trading days
immediately preceding and including the third trading day prior to the
repurchase date. We may only pay the repurchase price in our Class A Common
Stock if we satisfy conditions provided in the Indenture.

     Within 30 days after the occurrence of a Change in Control, we are
obligated to give to the holders of notes notice of the Change in Control and of
the repurchase right arising as a result of the Change in Control and to make a
public announcement thereof by release made to Reuters Economic Services and
Bloomberg Business News. We must also deliver a copy of this notice to the
Trustee. To exercise the repurchase right, a holder of notes must deliver on or
before the 30th day after the date of our notice irrevocable written notice to
the Trustee of the holders exercise of its repurchase right, together with the

                                        18
   21

notes with respect to which the right is being exercised. We are required to
repurchase the notes on the date that is 45 days after the date of our notice.

     A Change in Control will be deemed to have occurred at the time after the
notes are originally issued that any of the following occurs:

          (1) any person, including any syndicate or group deemed to be a
     "person" under Section 13(d)(3) of the Exchange Act, acquires beneficial
     ownership, directly or indirectly, through a purchase, merger or other
     acquisition transaction or series of transactions, of shares of our capital
     stock entitling the person to exercise 50% or more of the total voting
     power of all shares of our capital stock that is entitled to vote generally
     in elections of directors, other than (i) an acquisition by us, any of our
     subsidiaries or any of our employee benefit plans or (ii) any such
     acquisition by Mr. Darwin Deason, the Deason International Trust or any
     person controlled by Mr. Deason or the Deason International Trust, so long
     as any such acquisition does not result, directly or indirectly, in a
     "going private transaction" within the meaning of the Exchange Act; or

          (2) we merge or consolidate with or into any other person, any merger
     of another person into us, or we convey, sell, transfer or lease all or
     substantially all of our assets to another person, other than any such
     transaction:

          - that does not result in any reclassification, conversion, exchange
            or cancellation of outstanding shares of our capital stock, and
            pursuant to which the holders of our Class A Common Stock
            immediately prior to such transaction have the entitlement to
            exercise, directly or indirectly, 50% or more of the total voting
            power of all shares of capital stock entitled to vote generally in
            the election of directors of the continuing or surviving corporation
            immediately after such transaction; or

          - which is effected solely to change our jurisdiction of incorporation
            and results in a reclassification, conversion or exchange of
            outstanding shares of our Class A Common Stock solely into shares of
            Class A Common Stock of the surviving entity.

     However, a Change in Control will not be deemed to have occurred if either:

     - the closing price per share of our Class A Common Stock for any five
       trading days within the period of 10 consecutive trading days ending
       immediately after the later of the Change in Control or the public
       announcement of the Change in Control, in the case of a Change in Control
       relating to an acquisition of capital stock, or the period of 10
       consecutive trading days ending immediately before the Change in Control,
       in the case of Change in Control relating to a merger, consolidation or
       asset sale, equals or exceeds 105% of the conversion price of the notes
       in effect on each of those trading days; or

     - all of the consideration (excluding cash payments for fractional shares
       and cash payments made pursuant to dissenters' appraisal rights) in a
       merger or consolidation otherwise constituting a Change in Control under
       clause (1) and/or clause (2) above consists of shares of common stock
       traded on a national securities exchange or quoted on the NASDAQ National
       Market (or will be so traded or quoted immediately following such merger
       or consolidation) and as a result of such merger or consolidation the
       notes become convertible into such common stock.

     For purposes of these provisions:

     - the conversion price is equal to $1,000 divided by the conversion rate;

     - whether a person is a "beneficial owner" will be determined in accordance
       with Rule 13d-3 under the Exchange Act; and

     - "person" includes any syndicate or group that would be deemed to be a
       "person" under Section 13(d)(3) of the Exchange Act.

     Rule 13e-4 under the Exchange Act requires the dissemination of prescribed
information to security holders in the event of an issuer tender offer and may
apply in the event that the repurchase option becomes available to you. We will
comply with this rule to the extent it applies at that time.
                                        19
   22

     The definition of Change in Control includes a phrase relating to the
conveyance, transfer, sale, lease or disposition of "all or substantially all"
of our assets. There is no precise, established definition of the phrase
"substantially all" under applicable law. Accordingly, the ability of a holder
to require us to repurchase its notes as a result of conveyance, transfer, sale,
lease or other disposition of less than all of our assets may be uncertain.

     The foregoing provisions would not necessarily provide the holders of notes
with protection if we are involved in a highly leveraged or other transaction
that may adversely affect the holders.

     Our ability to repurchase notes upon the occurrence of a Change in Control
is subject to important limitations. Some of the events constituting a Change in
Control could result in or cause an event of default under, or be prohibited or
limited by, the terms of our Senior Indebtedness. The terms of our credit
facility prohibit the prepayment of any principal of, or interest on, the notes,
except exchanges of the notes for other notes, conversions of the notes into our
equity that is not mandatorily redeemable and up to $3 million in cash
redemptions. As a result, unless we were to obtain a waiver, a repurchase of the
notes in cash could be prohibited under the subordination provisions of the
Indenture until the Senior Indebtedness is paid in full. Although we have the
right to repurchase the notes with our Class A Common Stock, subject to certain
conditions, we cannot assure the holders of notes that we would have the
financial resources, or would be able to arrange financing, to pay the
repurchase price in cash for all the notes that might be delivered by holders of
notes seeking to exercise the repurchase right. If we were to fail to repurchase
the notes when required following a Change in Control, an Event of Default under
the Indenture would occur, whether or not such repurchase is permitted by the
subordination provisions of the Indenture. Any such default may, in turn, cause
a default under our Senior Indebtedness. See "-- Subordination."

MERGERS AND SALES OF ASSETS

     We may not consolidate with or merge into any other person or convey,
transfer, sell or lease our properties and assets substantially as an entirety
to any person unless:

     - the person formed by such consolidation or into or with which we are
       merged or the person to which our properties and assets are so conveyed,
       transferred, sold or leased, is a corporation, limited liability company,
       partnership or trust organized and existing under the laws of the United
       States, any State within the United States or the District of Columbia;

     - if we are not the surviving person, the surviving person assumes the
       payment of the principal of, premium, if any, and interest on the notes
       and the performance of our other covenants under the Indenture; and

     - immediately after giving effect to the transaction, no Event of Default,
       and no event that, after notice or lapse of time or both, would become an
       Event of Default, will have occurred and be continuing.

EVENTS OF DEFAULT

     The following will be Events of Default under the Indenture:

     - we fail to pay principal of or premium, if any, on any note when due,
       whether or not prohibited by the subordination provisions of the
       Indenture;

     - we fail to pay any interest, including any Liquidated Damages, on any
       note when due, which failure continues for 30 days, whether or not
       prohibited by the subordination provisions of the Indenture;

     - we fail to provide notice of a Change in Control, whether or not such
       notice is prohibited by the subordination provisions of the Indenture;

     - we fail to perform any other covenant in the Indenture, which failure
       continues for 60 days after written notice as provided in the Indenture;

     - any indebtedness under any bonds, debentures, notes or other evidences of
       indebtedness for money borrowed (or any guarantee thereof) by us in an
       aggregate principal amount in excess of

                                        20
   23

       $25,000,000 is not paid when due either at its stated maturity or upon
       acceleration thereof, and such indebtedness is not discharged, or such
       acceleration is not rescinded or annulled, within a period of 30 days
       after notice as provided in the Indenture; and

     - certain events of bankruptcy, insolvency or reorganization involving us.

     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any holder, unless the holder shall
have offered reasonable indemnity to the Trustee. Subject to providing
indemnification of the Trustee, the holders of a majority in aggregate principal
amount of the outstanding notes will have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.

     If an Event of Default (other than an Event of Default arising from events
of insolvency, bankruptcy or reorganization with respect to us) occurs and is
continuing, either the Trustee or the holders of at least 25% in principal
amount of the outstanding notes may, subject to the subordination provisions of
the Indenture, accelerate the maturity of all notes. However, after such
acceleration, but before a judgment or decree based on acceleration, the holders
of a majority in aggregate principal amount of outstanding notes may, under
certain circumstances, rescind and annul the acceleration if all Events of
Default, other than the non-payment of principal of the notes which have become
due solely by such declaration of acceleration, have been cured or waived as
provided in the Indenture. If an Event of Default arising from events of
insolvency, bankruptcy or reorganization with respect to us occurs, then the
principal of, and accrued interest on, all the notes will automatically become
immediately due and payable without any declaration or other act on the part of
the holders of the notes or the Trustee. For information as to waiver of
defaults, see "-- Meetings, Modification and Waiver."

     A holder of notes will not have any right to institute any proceeding with
respect to the Indenture, or for any remedy under the Indenture, unless:

     - the holder gives the Trustee written notice of a continuing Event of
       Default;

     - the holders of at least 25% in aggregate principal amount of the
       outstanding notes have made written request and offered reasonable
       indemnity to the Trustee to institute proceedings; and

     - the Trustee has not received from the holders of a majority in aggregate
       principal amount of the outstanding notes a direction inconsistent with
       the written request and shall have failed to institute such proceeding
       within 60 days.

However, these limitations do not apply to a suit instituted by a holder of
notes for the enforcement of payment of the principal of, premium, if any, or
interest, including Liquidated Damages, on the holder's note on or after the
respective due dates expressed in its note or the holder's right to convert its
note in accordance with the Indenture.

     We will be required to furnish to the Trustee annually a statement as to
our performance of certain of our obligations under the Indenture and as to any
default in such performance.

MEETINGS, MODIFICATION AND WAIVER

     The Indenture contains provisions for convening meetings of the holders of
notes to consider matters affecting their interests.

     Certain limited modifications of the Indenture may be made without the
necessity of obtaining the consent of the holders of the notes. Other
modifications and amendments of the Indenture may be made, and certain past
defaults by us may be waived, either (i) with the written consent of the holders
of not less than a majority in aggregate principal amount of the notes at the
time outstanding or (ii) by the adoption of a resolution, at a meeting of
holders of the notes at which a quorum is present, by the holders of at least
66 2/3% in aggregate principal amount of the notes represented at such meeting.
The quorum at any meeting called to adopt a resolution will be persons holding
or representing a majority in aggregate

                                        21
   24

principal amount of the notes at the time outstanding and, at any reconvened
meeting adjourned for lack of a quorum, 25% of such aggregate principal amount.

     However, a modification or amendment requires the consent of the holder of
each outstanding note affected if it would:

     - change the stated maturity of the principal or interest of a note;

     - reduce the principal amount of, or any premium or interest on, any note;

     - reduce the amount payable upon a redemption or mandatory repurchase;

     - modify the provisions with respect to the repurchase rights of holders of
       notes in a manner adverse to the holders;

     - change the place or currency of payment on a note;

     - impair the right to institute suit for the enforcement of any payment on
       any note;

     - modify our obligation to maintain an office or agency in New York City;

     - modify the subordination provisions in a manner that is adverse to the
       holders of the notes;

     - adversely affect the right to convert the notes;

     - modify our obligation to deliver information required under Rule 144A to
       permit resales of the notes and Class A Common Stock issued upon
       conversion of the notes if we cease to be subject to the reporting
       requirements under the Exchange Act;

     - reduce the above-stated percentage of the principal amount of the holders
       whose consent is needed to modify or amend the Indenture;

     - reduce the percentage of the principal amount of the holders whose
       consent is needed to waive compliance with certain provisions of the
       Indenture or to waive certain defaults; or

     - reduce the percentage required for the adoption of a resolution or the
       quorum required at any meeting of holders of notes at which a resolution
       is adopted.

     The holders either through written consent of a majority in aggregate
principal amount of the outstanding notes or by the adoption of a resolution, at
a meeting of holders of the outstanding notes at which a quorum is present, by
the holders of at least 66 2/3% in aggregate principal amount of notes
represented at such meeting may waive any past default under the Indenture,
except a default in the payment of principal, premium, if any, or interest which
has not been cured or in respect of a provision which cannot be modified or
amended without the consent of all the holders affected.

REGISTRATION RIGHTS

     The registration statement of which this prospectus forms a part has been
filed under the terms of a Registration Rights Agreement, which we entered into
with the initial purchasers of the notes. In the Registration Rights Agreement
we agreed, for the benefit of the holders of the notes and the shares of Class A
Common Stock issuable upon conversion of the notes (together, the "Registrable
Securities") that we would, at our expense:

     - file with the SEC, within 90 days after the date the notes were
       originally issued, a shelf registration statement covering resales of the
       Registrable Securities;

     - use our reasonable efforts to cause the shelf registration statement to
       be declared effective under the Securities Act within 180 days after the
       date the notes were originally issued, subject to our right to postpone
       having the shelf registration statement declared effective for an
       additional 90 days in limited circumstances; and

     - use our reasonable efforts to keep effective the shelf registration
       statement until two years after the date the notes were issued or, if
       earlier, until there are no outstanding Registrable Securities (the
       "Effectiveness Period").

                                        22
   25

     We will be permitted to suspend the use of the prospectus that is part of
the shelf registration statement in connection with the sales of Registrable
Securities during prescribed periods of time for reasons relating to pending
corporate developments, public filings with the SEC and other events. Following
the effectiveness of the registration statement of which this prospectus forms a
part, we will provide to each holder of Registrable Securities copies of this
prospectus, notify each holder when the shelf registration statement has become
effective and take certain other actions required to permit public resales of
the Registrable Securities.

     We may, upon written notice to all the holders of Registrable Securities,
postpone having the shelf registration statement declared effective, in each
case, for a reasonable period not to exceed 90 days if we in good faith
reasonably believe that we possess material non-public information the
disclosure of which would have a material adverse effect on us and our
subsidiaries taken as a whole. Notwithstanding any such postponement, damages
("Liquidated Damages") will accrue on the notes (or on the Class A Common Stock
into which any notes have been converted) if either of the following events
("Registration Defaults") occurs:

     - on or prior to 90 days following the date the notes were originally
       issued, a shelf registration statement has not been filed with the SEC;
       or

     - on or prior to 180 days following the date the notes were originally
       issued, the shelf registration statement is not declared effective.

     In that case, Liquidated Damages will accrue on the Registrable Securities
from and including the day following the Registration Default to but excluding
the day on which the Registration Default has been cured. Liquidated Damages
will be paid semi-annually in arrears, with the first semi-annual payment due on
the first Interest Payment Date following the date on which the Liquidated
Damages began to accrue. Liquidated Damages for any day accrue either on the
principal amount of the notes or based on the then current conversion price of
Class A Common Stock issuable upon conversion of the notes.

     The rates at which Liquidated Damages will accrue will be as follows:

     - 0.25% of the principal amount (or the conversion price) per annum to and
       including the 90th day after the Registration Default; and

     - 0.50% of the principal amount (or the conversion price) per annum from
       and after the 91st day after the Registration Default.

     In addition, Liquidated Damages will accrue if:

     - the shelf registration statement ceases to be effective, or we otherwise
       prevent or restrict holders of Registrable Securities from making sales
       under the shelf registration statement, for more than 30 days, whether or
       not consecutive during any 90-day period; or

     - the shelf registration statement ceases to be effective, or we otherwise
       prevent or restrict holders of Registrable Securities from making sales
       under the shelf registration statement, for more than 90 days, whether or
       not consecutive, during any 12-month period.

     In either event, we will pay Liquidated Damages at a rate of 0.50% per
annum from the 31st day of the 90-day period or the 91st day of the 12-month
period. The Liquidated Damages will continue to accrue until the earlier of the
following:

     - the time the shelf registration statement again becomes effective or the
       holders of Registrable Securities are again able to make sales under the
       shelf registration statement, depending on which event triggered the
       increase in interest rate; or

     - the date the Effectiveness Period expires.

     A holder who elects to sell any Registrable Securities pursuant to the
shelf registration statement will be required to be named as a selling security
holder in the related prospectus, may be required to deliver a prospectus to
purchasers, may be subject to certain civil liability provisions under the
Securities Act in

                                        23
   26

connection with those sales and will be bound by the provisions of the
Registration Rights Agreement that apply to a holder making such an election,
including certain indemnification provisions.

     We will mail the Notice and Questionnaire to the holders of Registrable
Securities not less than 30 calendar days prior to the time we intend in good
faith to have the shelf registration statement declared effective (the
"Effective Time").

     No holder of Registrable Securities will be entitled to be named as a
selling security holder in the shelf registration statement as of the Effective
Time, and no holder of Registrable Securities will be entitled to use this
prospectus for offers and resales of Registrable Securities at any time, unless
such holder has returned a completed and signed Notice and Questionnaire to us
by the deadline for response set forth in the Notice and Questionnaire. Holders
of Registrable Securities will, however, have at least 28 calendar days from the
date on which the Notice and Questionnaire is first mailed to them to return a
completed and signed Notice and Questionnaire to us.

     Beneficial owners of Registrable Securities who have not returned a Notice
and Questionnaire by the questionnaire deadline described above may receive
another Notice and Questionnaire from us upon request. Following our receipt of
a completed and signed Notice and Questionnaire, we will include the Registrable
Securities covered thereby in the shelf registration statement, subject to
restrictions on the timing and number of supplements to the shelf registration
statement provided in the Registration Rights Agreement.

     We agreed in the Registration Rights Agreement to use our reasonable
efforts to cause the shares of Class A Common Stock issuable upon conversion of
the notes to be listed on the New York Stock Exchange or other stock exchange or
trading system on which shares of Class A Common Stock primarily trade on or
prior to the effectiveness of the shelf registration statement.

     This summary of certain provisions of the Registration Rights Agreement may
not contain all the information important to the holders of notes. We will
provide holders of notes a copy of the Registration Rights Agreement upon
request.

NOTICES

     Notice to holders of the registered notes will be given by mail to the
addresses as they appear in the security register. Such notices will be deemed
to have been given on the date of such mailing.

     Notice of a redemption of notes will be given not less than 30 nor more
than 60 days prior to the redemption date and will specify the redemption date.
A notice of redemption of the notes will be irrevocable.

REPLACEMENT OF NOTES

     We will replace any note that becomes mutilated, destroyed, stolen or lost
at the expense of the holder upon delivery to the Trustee of the mutilated notes
or evidence of the loss, theft or destruction satisfactory to us and the
Trustee. In the case of a lost, stolen or destroyed note, indemnity satisfactory
to the Trustee and us may be required at the expense of the holder of the note
before a replacement note will be issued.

PAYMENT OF STAMP AND OTHER TAXES

     We will pay all stamp and other duties, if any, which may be imposed by the
United States or any political subdivision thereof or taxing authority thereof
or therein with respect to the issuance of the notes. We will not be required to
make any payment with respect to any other tax, assessment or governmental
charge imposed by any government or any political subdivision thereof or taxing
authority thereof or therein.

GOVERNING LAW

     The Indenture and the notes are governed by and construed in accordance
with the laws of the State of New York, United States of America.

                                        24
   27

THE TRUSTEE

     If an Event of Default occurs and is continuing, the Trustee will be
required to use the degree of care of a prudent person in the conduct of his own
affairs in the exercise of its powers. Subject to such provisions, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request of any of the holders of notes, unless they shall have
offered to the Trustee reasonable security or indemnity.

                          DESCRIPTION OF CAPITAL STOCK

     We are authorized to issue up to 500,000,000 shares of Class A Common
Stock, $.01 par value, up to 14,000,000 shares of Class B Common Stock, $.01 par
value, and up to 3,000,000 shares of preferred stock, $1.00 par value. As of
March 31, 2001, we had issued and outstanding 46,741,598 shares of Class A
Common Stock held by 519 stockholders of record, 3,299,686 shares of Class B
Common Stock held by one holder of record, and no shares of preferred stock. As
of December 31, 2000, 5,521,984 shares of Class A Common Stock were subject to
outstanding options. In addition, up to 5,391,936 shares of Class A Common Stock
could be issued upon conversion of our 4% convertible subordinated notes due
March 15, 2005 in the aggregate principal amount of $230 million at a conversion
price of $42.66 per share (equivalent to a conversion rate of 23.4432 shares per
$1,000 principal amount of 4% notes), and 3,299,686 shares of Class A Common
Stock could be issued upon conversion of all outstanding shares of Class B
Common Stock.

     The relative rights and limitations of the Class A Common Stock and the
Class B Common Stock, as well as our preferred stock, are summarized below. We
refer you to the certificate of incorporation and the bylaws, copies of which
have been filed as exhibits to our reports or registration statements filed with
the Securities and Exchange Commission, for the complete terms of our capital
stock.

PREFERRED STOCK

     Our Board of Directors has the authority, without further action by the
stockholders, to:

     - issue up to 3,000,000 shares of preferred stock in one or more series;

     - fix the rights, preferences, privileges and restrictions granted to or
       imposed upon any unissued shares of preferred stock; and

     - fix the number of shares constituting any series and the designations of
       the series.

     The issuance of preferred stock could adversely affect the voting power of
the holders of Class A Common Stock and the likelihood that holders will receive
dividend payments and payments upon liquidation and may have the effect of
delaying, deferring or preventing a change in control of the Company.

CLASS A COMMON STOCK AND CLASS B COMMON STOCK

  Voting Rights

     Each share of Class A Common Stock is entitled to one vote and each share
of Class B Common Stock is entitled to ten votes on all matters submitted to a
vote of the stockholders. Except as otherwise provided by law, Class A Common
Stock and Class B Common Stock vote together as a single class on all matters
presented for a vote of the stockholders. Neither class of our common stock has
cumulative voting rights.

  Conversion

     Class A Common Stock has no conversion rights. Each share of Class B Common
Stock is convertible at any time, at the option of and without cost to the
stockholder, into one share of Class A Common Stock upon surrender to our
transfer agent of the certificate or certificates evidencing the Class B Common
Stock to be converted, together with a written notice of the election of a
stockholder to convert shares into Class A Common Stock. Shares of Class B
Common Stock will also be automatically converted into shares of Class A Common
Stock on the occurrence of events described below. Once shares of Class B Common
Stock are converted into shares of Class A Common Stock, the shares may not be
converted back into Class B Common Stock.

  Restrictions on Transfer of Class B Common Stock

     No person or entity holding shares of Class B Common Stock may transfer the
shares, whether by sale, assignment, gift, bequest, appointment or otherwise,
except to a permitted transferee (as described

                                        26
   29

below). In the case of a Class B holder who is a natural person and the
beneficial owner of shares of Class B Common Stock to be transferred, a
permitted transferee consists of:

     - the Class B holder's spouse; provided, however, that upon divorce any
       Class B Common Stock held by the spouse shall automatically be converted
       into Class A Common Stock;

     - any lineal descendant of any great-grandparent of the Class B holder,
       including adopted children, and the descendant's spouse (the descendants
       and their spouses, together with the Class B holder's spouse, are
       referred to as "family members");

     - the trustee of a trust for the sole benefit of the Class B holder or any
       of the Class B holder's family members;

     - any charitable organization established by the Class B holder or any of
       the Class B holder's family members;

     - any partnership made up exclusively of the Class B holder and any of the
       Class B holder's family members or any corporation wholly-owned by the
       Class B holder and any of the Class B holder's family members; provided
       that, if there is any change in the partners of the partnership or in the
       stockholders of the corporation that would cause the partnership or
       corporation no longer to be a permitted transferee, any Class B Common
       Stock held by the partnership or corporation shall automatically be
       converted into Class A Common Stock;

     - in the case of a Class B holder that is a partnership or corporation, (1)
       the partnership's partners or the corporation's stockholders, as the case
       may be, (2) any transferor to the partnership or corporation of shares of
       Class B Common Stock after the record date of the initial distribution of
       Class B Common Stock and (3) successors by merger or consolidation;

     - in the case of a Class B holder that is an irrevocable trust on the
       record date of the distribution of Class B Common Stock, (1) successor
       trustees of the trust, (2) any person to whom or for whose benefit
       principal or income may be distributed under the terms of the trust or
       any person to whom the trust may be obligated to make future transfers,
       provided the obligation exists prior to the date the trust becomes a
       holder of Class B Common Stock and (3) any family member of the creator
       of the trust; and

     - in the case of a Class B holder that is any trust other than an
       irrevocable trust on the date of the distribution of Class B Common
       Stock, (1) successor trustees of the trust and (2) the person who
       established the trust and the person's permitted transferees.

     Upon the death or permanent incapacity of any Class B holder, the holder's
Class B Common Stock shall automatically be converted into Class A Common Stock.
All shares of Class B Common Stock will automatically convert into shares of
Class A Common Stock on the ninetieth day after the death of Darwin Deason or
upon the conversion by Mr. Deason of all Class B Common Stock beneficially owned
by Mr. Deason into shares of Class A Common Stock.

     Subject to compliance with applicable securities laws, shares of Class B
Common Stock are freely transferable among permitted transferees, but any other
transfer of Class B Common Stock will result in its automatic conversion into
Class A Common Stock. The restriction on transfers of shares of Class B Common
Stock to other than a permitted transferee may preclude or delay a change in
control of our capital stock.

  Dividends and Liquidation Rights

     The holders of Class A Common Stock and Class B Common Stock are entitled
to receive dividends out of assets legally available therefore at times and in
amounts as the Board of Directors may from time to time determine. Upon
liquidation and dissolution of ACS, the holders of Class A Common Stock and
Class B Common Stock are entitled to receive all assets available for
distribution to stockholders.

                                        27
   30

  Other Rights

     The holders of Class A Common Stock and Class B Common Stock are not
entitled to preemptive or subscription rights, and there are no redemption or
sinking fund provisions applicable to the common stock.

RIGHTS AGREEMENT

     On August 5, 1997, we entered into a rights agreement and authorized and
declared a dividend distribution of one right for each share of Class A Common
Stock and one right for each share of Class B Common Stock, each as outstanding
at the close of business on August 25, 1997. Class A Common Stock and Class B
Common Stock issued after August 25, 1997 will be issued with an associated
right. Each right entitles the registered holder to purchase from us one share
of Class A Common Stock at an exercise price of $150.00 per share, subject to
adjustment from time to time.

SUMMARY OF CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of certain material United States federal income
tax considerations relating to the purchase, ownership and disposition of the
notes and the Class A Common Stock into which the notes may be converted, but
does not purport to be a complete analysis of all the potential tax
considerations relating thereto.

     We have based this summary on the provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), the applicable Treasury Regulations
promulgated or proposed thereunder (the "Treasury Regulations"), and judicial
authority and current administrative rulings and practice, all of which are
subject to change, possibly on a retroactive basis, and to different
interpretations. This summary applies to you only if you hold the notes and
Class A Common Stock as capital assets for United States federal income tax
purposes. A capital asset is generally an asset held for investment rather than
as inventory or as property used in a trade or business. This summary also does
not discuss the particular tax consequences that might be relevant to you if you
are subject to special rules under the federal income tax laws. Special rules
apply, for example, if you are:

     - a bank, thrift, insurance company, regulated investment company, or other
       financial institution or financial service company,

     - a broker or dealer in securities or foreign currency,

     - a person that has a functional currency other than the U.S. dollar,

     - a partnership or other flow-through entity,

     - a subchapter S corporation,

     - a person subject to alternative minimum tax,

     - a person who owns the notes or Class A Common Stock as part of a
       straddle, hedging transaction, conversion transaction, constructive sale
       transaction or other risk-reduction transaction,

     - a tax-exempt entity,

     - a person who has ceased to be a United States citizen or to be taxed as a
       resident alien, or

     - a person who acquires the notes or Class A Common Stock in connection
       with his or her employment or other performance of services.

     In addition, the following summary does not address all possible tax
consequences. In particular, except as specifically provided, it does not
discuss any estate, gift, generation-skipping, transfer, state, local or foreign
tax consequences. We have not sought any ruling from the Internal Revenue
Service (the "IRS"), with respect to the statements made and the conclusions
reached in the following summary, and there can be no assurance that the IRS
will agree with such statements and conclusions. For all these reasons, we urge
you to consult with your tax advisor about the federal income tax and other tax
consequences of the acquisition, ownership and disposition of the notes and
Class A Common Stock.

     INVESTORS CONSIDERING THE PURCHASE OF THE NOTES SHOULD CONSULT THEIR OWN
TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME
TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING
UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY
APPLICABLE TAX TREATY.

IN GENERAL

     The notes should be treated as indebtedness for federal income tax
purposes, and this summary assumes that the notes will be so treated by the IRS.

     The discussion below applies to those beneficial owners of the notes or
Class A Common Stock who, for federal income tax purposes, are:

     - a citizen or resident of the United States, including an alien individual
       who is a lawful permanent resident of the United States or who meets the
       substantial presence residency test under the federal income tax laws,

                                        29
   32

     - a corporation, partnership or other entity treated as a corporation or
       partnership for federal income tax purposes, that is created or organized
       in or under the laws of the United States, any of the fifty states or the
       District of Columbia, unless otherwise provided by Treasury Regulations,

     - an estate the income of which is subject to federal income taxation
       regardless of its source, or

     - a trust if a court within the United States is able to exercise primary
       supervision over the administration of the trust and one or more United
       States persons have the authority to control all substantial decisions of
       the trust,

and if such status is not overridden under the provisions of an applicable tax
treaty.

PAYMENT OF INTEREST

     All of the notes bear interest at a stated fixed rate. You generally must
include this stated interest in your gross income as ordinary interest income:

     - when you receive it, if you use the cash method of accounting for federal
       income tax purposes, or

     - when it accrues, if you use the accrual method of accounting for federal
       income tax purposes.

CONVERSION OF NOTES

     You generally will not recognize gain or loss on the conversion of the
notes solely into Class A Common Stock, except with respect to cash received in
lieu of fractional shares. Your tax basis in the shares of Class A Common Stock
received upon conversion of the notes will be equal to your adjusted tax basis
in the notes exchanged therefor (less any portion thereof allocable to cash
received in lieu of a fractional share of Class A Common Stock). The holding
period of the Class A Common Stock will generally include the period during
which you held the notes prior to conversion. Cash received in lieu of a
fractional share of Class A Common Stock should generally be treated as a
payment in exchange for such fractional share rather than as a dividend. You
generally will recognize capital gain or loss on the receipt of cash paid in
lieu of such fractional shares equal to the difference between the amount of
cash received for the fractional shares and the amount of tax basis allocable to
the fractional shares.

SALE, EXCHANGE OR REDEMPTION OF NOTES OR SHARES OF CLASS A COMMON STOCK

     You generally will recognize capital gain or loss upon the sale, exchange,
redemption, retirement or other disposition of the notes (other than a
conversion) measured by the difference between (i) the amount of cash and the
fair market value of any property you receive on the sale, exchange, redemption,
or other disposition (except to the extent attributable to accrued interest not
previously included in income, which will generally be taxable as ordinary
income, or attributable to accrued interest previously included in income, which
amount may be received without generating further income), and (ii) your
adjusted tax basis in the notes. Your adjusted tax basis in a note generally
will equal your cost of the note, less any principal payments received by you.
In general, if you hold Class A Common Stock into which the notes have been
converted, you will recognize capital gain or loss upon the sale, exchange, or
other disposition of the Class A Common Stock measured by the difference between
(i) the amount of cash and the fair market value of any property you receive,
and (ii) your adjusted tax basis in the Class A Common Stock. (For a discussion
of the basis and holding period of shares of Class A Common Stock, see
"-- Conversion of Notes" above.) Gain or loss on the disposition of notes or
Class A Common Stock will generally be long-term capital gain or loss if the
notes or shares of Class A Common Stock have been held for more than one year at
the time of such disposition. In general, for individuals, long-term capital
gains are currently taxed at a maximum rate of 20% and short-term capital gains
and ordinary income are currently taxed at a maximum rate of 39.6%.

CONSTRUCTIVE DIVIDENDS ON NOTES

     Under Treasury Regulations, an adjustment in the conversion price, or the
failure to make such an adjustment, may, under particular circumstances, be
treated as a constructive taxable dividend to the extent of our current or
accumulated earnings and profits. Adjustments to the conversion price made
pursuant to a bona fide reasonable adjustment formula which has the effect of
preventing the dilution of
                                        30
   33

your interest as a holder of the notes generally will not be considered to
result in a constructive distribution of stock where the adjustment does not
compensate you for taxable distributions to other stockholders. However, if at
any time

           (i) we make a distribution of cash or property to, or purchase Class
               A Common Stock from, our stockholders, and such distribution or
               purchase would be taxable to such stockholders as a dividend for
               United States federal income tax purposes and, pursuant to the
               anti-dilution provisions of the Indenture, the conversion price
               (as defined in the Indenture) of the notes is reduced,

           (ii) the conversion price is reduced pursuant to a formula that is
                not a bona fide reasonable adjustment formula, or

          (iii) the conversion price of the notes is reduced at our discretion,

such reduction in conversion price may be deemed to be the payment of a taxable
dividend to you as a holder of the notes (pursuant to Section 305 of the Code)
to the extent paid out of our current or accumulated earnings and profits. You
could therefore have taxable income as a result of an event pursuant to which
you received no cash or property. Your tax basis in a note, however, generally
will be increased by the amount of any constructive dividend included in your
income.

DISTRIBUTIONS ON CLASS A COMMON STOCK

     The amount of any distribution by us on the Class A Common Stock will be
equal to the amount of cash and the fair market value, on the date of
distribution, of any property distributed. Generally, distributions will be
treated as follows:

     - first as ordinary dividend income to the extent paid out of our current
       or accumulated earnings and profits,

     - next as a nontaxable return of capital that reduces your basis in the
       stock dollar-for-dollar until the basis has been reduced to zero, and

     - finally as capital gain from the sale or exchange of the stock.

     In general, if you are a corporation for U.S. federal income tax purposes,
you will qualify for the 70% dividends-received deduction if you own less than
20% of the voting power and value of our stock. If you are a corporation that
owns 20% or more of the voting power and value of our stock (other than any non-
voting, non-convertible, non-participating preferred stock) generally you will
qualify for an 80% dividends-received deduction. The dividends-received
deduction is subject, however, to certain holding period requirements and
taxable income and other limitations.

     A failure to fully adjust the conversion price of the notes to reflect a
stock dividend or other event increasing the proportionate interest of holders
of Class A Common Stock in our earnings and profits or assets could, in some
circumstances, be deemed to result in the payment of a taxable dividend to
holders of Class A Common Stock.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

     In general, we will be required to report to the IRS "reportable payments"
made to certain persons other than those treated as corporations for U.S.
federal income tax purposes. "Reportable payments" would include principal and
interest on a note, dividends on Class A Common Stock, the proceeds of the sale
of a note and the proceeds of the sale of Class A Common Stock. If you are a
noncorporate holder of notes or Class A Common Stock you may be subject to
backup withholding at a 31% rate when you receive interest and dividends with
respect to the notes or Class A Common Stock, or when you receive proceeds upon
the sale, exchange, redemption, retirement or other disposition of the notes or
Class A

                                        31

Common Stock. In general, you can avoid this backup withholding by properly
executing under penalties of perjury an IRS Form W-9 or substantially similar
form that provides:

     - your correct taxpayer identification number, and

     - a certification that (a) you are exempt from backup withholding because
       you are a corporation or come within another enumerated exempt category,
       (b) you have not been notified by the IRS that you are subject to backup
       withholding as a result of a failure to report all interest or dividends,
       or (c) you have been notified by the IRS that you are no longer subject
       to backup withholding.

     If you do not provide your correct taxpayer identification number on the
IRS Form W-9 or substantially similar form, you may be subject to penalties
imposed by the IRS.

     Backup withholding will not apply, however, with respect to payments made
to certain holders, including corporations, tax exempt organizations and certain
foreign persons, provided their exemptions from backup withholding are properly
established.

     Amounts withheld are generally not an additional tax and may be refunded or
credited against your federal income tax liability, provided you furnish the
required information to the IRS.

     We will report to the holders of notes and Class A Common Stock and to the
IRS the amount of any "reportable payments" for each calendar year and the
amount of tax withheld, if any, with respect to such payments.

                            SELLING SECURITYHOLDERS

     We originally sold the notes on February 21, 2001 and March 20, 2001 to
Goldman, Sachs & Co. and Bear, Stearns & Co. Inc. in a private placement. The
initial purchasers of the notes have advised us that the notes were resold in
transactions exempt from the registration requirements of the Securities Act to
"qualified institutional buyers," as defined in Rule 144A of the Securities Act.
These subsequent purchasers, or their transferees, pledgees, donees or
successors, may from time to time offer and sell any or all of the notes and/or
shares of Class A Common Stock issuable upon conversion of the notes pursuant to
this prospectus.

     The notes and Class A Common Stock issuable upon conversion of the notes
are being registered in accordance with the Registration Rights Agreement.
Pursuant to the Registration Rights Agreement, we are required to file a
registration statement with regard to the notes and the shares of our Class A
Common Stock issuable upon conversion of the notes and to keep the registration
statement effective until the earlier of:

          (1) the sale of all the securities registered under the registration
              statement;

          (2) the expiration of the holding period applicable to these
              securities under Rule 144(k) under the Securities Act with respect
              to persons who are not our affiliates; and

          (3) two years from the date the registration statement is declared
              effective.

     The selling securityholders may choose to sell the notes and/or the Class A
Common Stock issuable upon conversion of the notes from time to time. See "Plan
of Distribution".

     The following table sets forth the name of each selling securityholder and
relationship, if any, with us and (i) the amount of notes owned by each selling
securityholder as of May 24, 2001 (assuming no notes have been sold under this
prospectus as of such date), and the maximum amount of notes which may be
offered for the account of such selling securityholder under the prospectus,
(ii) the amount of Class A Common Stock beneficially owned by each selling
securityholder as of May 24, 2001 and (iii) the maximum amount of Class A Common
Stock which may be offered for the account of such selling securityholder under
the prospectus.

(1) No such holder may offer notes pursuant to the registration statement of
    which this prospectus forms a part until such holder is included as a
    selling securityholder in a supplement to this prospectus in accordance with
    the Registration Rights Agreement.

(2) Assumes conversion into Class A Common Stock of the full amount of notes
    held by the selling securityholder at the initial conversion rate and the

    notes is subject to adjustment under certain circumstances. See "Description
    of Notes -- Conversion Rights." Accordingly, the number of shares of Class A
    Common Stock issuable upon conversion of the notes may increase or decrease
    from time to time. Fractional shares will not be issued upon conversion of
    the notes; rather, cash will be paid in lieu of fractional shares, if any.

(3) No selling securityholder will own one percent or more of the Class A Common
    Stock relating to this offering after completion of the offering.

(4) Bear, Stearns & Co. Inc. or one of its affiliates was the manager or

(6) Information about other selling securityholders will be set forth in
    prospectus supplements, if required.

     Because the selling securityholders may, pursuant to this prospectus, offer
all or some portion of the notes they presently hold, no estimate can be given
as to the amount of the notes that will be held by the selling securityholders
upon termination of any such sales. In addition, the selling securityholders
identified above may have sold, transferred or otherwise disposed of all or a
portion of their notes since the date on which they provided the information
regarding their notes, in transactions exempt from the registration requirements
of the Securities Act. See "Plan of Distribution."

     Only selling securityholders identified above who beneficially own the
notes set forth opposite each such selling securityholder's name in the
foregoing table on the effective date of the registration statement of which
this prospectus forms a part may sell such notes pursuant to the registration
statement. We may from time to time, in accordance with the Registration Rights
Agreement, include additional selling securityholders in supplements to this
prospectus.

     The Company will pay the expenses of registering the notes being sold
hereunder other than underwriting discounts, selling commissions and transfer
taxes.

                              PLAN OF DISTRIBUTION

     We are registering the notes and the shares of our Class A Common Stock
issuable upon conversion of the notes to permit public secondary trading of
these securities by the holders from time to time after the date of this
prospectus. We have agreed, among other things, to bear all expenses, other than
underwriting discounts, selling commissions and transfer taxes, in connection
with the registration and sale of the notes and the shares of our Class A Common
Stock issuable upon conversion of the notes covered by this prospectus.

     We will not receive any of the proceeds from the offering of the notes or
the shares of our Class A Common Stock issuable upon conversion of the notes by
the selling securityholders. The notes and shares of Class A Common Stock
issuable upon conversion of the notes may be sold from time to time directly by
any selling securityholder or, alternatively, through underwriters,
broker-dealers or agents. If notes or shares of Class A Common Stock issuable
upon conversion of the notes are sold through underwriters or broker-dealers,
the selling securityholder will be responsible for underwriting discounts or
commissions or agents' commissions.

     The notes or shares of Class A Common Stock issuable upon conversion of the
notes may be sold:

     - in one or more transactions at fixed prices,

     - at prevailing market prices at the time of sale,

     - at varying prices determined at the time of sale, or

     - at negotiated prices.

                                        38
   41

     These sales may be effected in transactions, which may involve block trades
or transactions in which the broker acts as agent for the seller and the buyer:

     - on any national securities exchange or quotation service on which the
       notes or shares of Class A Common Stock issuable upon conversion of the
       notes may be listed or quoted at the time of sale;

     - in the over-the-counter market;

     - in transactions otherwise than on a national securities exchange or
       quotation service or in the over-the-counter market; or

     - through the writing of options.

     In connection with sales of the notes or shares of Class A Common Stock
issuable upon conversion of the notes or otherwise, any selling securityholder
may:

     - enter into hedging transactions with broker-dealers, which may in turn
       engage in short sales of the notes or shares of Class A Common Stock
       issuable upon conversion of the notes in the course of hedging the
       positions they assume;

     - sell short and deliver notes or shares of Class A Common Stock issuable
       upon conversion of the notes to close out the short positions; or

     - loan or pledge notes or shares of Class A Common Stock issuable upon
       conversion of the notes to broker-dealers that in turn may sell the
       securities.

     The outstanding Class A Common Stock is publicly traded on the New York
Stock Exchange. The initial purchasers of the notes have advised us that certain
of the initial purchasers are making and currently intend to continue making a
market in the notes; however, they are not obligated to do so and any
market-making of this type may be discontinued at any time without notice, in
the sole discretion of the initial purchasers. We do not intend to apply for
listing of the notes on the New York Stock Exchange or any securities exchange.
Accordingly, we cannot assure that any trading market will develop or have any
liquidity.

     The selling securityholders and any broker-dealers, agents or underwriters
that participate with the selling securityholders in the distribution of the
notes or the shares of Class A Common Stock issuable upon conversion of the
notes may be deemed to be "underwriters" within the meaning of the Securities
Act, in which event any commissions received by these broker-dealers, agents or
underwriters and any profits realized by the selling securityholders on the
resales of the notes or the shares may be deemed to be underwriting commissions
or discounts under the Securities Act.

     In addition, any securities covered by this prospectus which qualify for
sale pursuant to Rule 144, Rule 144A or any other available exemption from
registration under the Securities Act may be sold under Rule 144, Rule 144A or
any of the other available exemptions rather than pursuant to this prospectus.

     There is no assurance that any selling securityholder will sell any or all
of the notes or shares of Class A Common Stock issuable upon conversion of the
notes described in this prospectus, and any selling securityholder may transfer,
devise or gift the securities by other means not described in this prospectus.

     We agreed to indemnify and hold the selling securityholders, each
underwriter, selling agent or other securities professional, if any, which
facilitates the disposition of the notes and the shares of our Class A Common
Stock issuable upon conversion of the notes, harmless against certain
liabilities under the Securities Act that could arise in connection with the
sale of the notes or the Class A Common Stock upon conversion of the notes by
the selling securityholders. The Registration Rights Agreement provides for us
and the selling securityholders, each underwriter, selling agent or other
securities professional, if any, which facilitates the disposition of the notes
and the shares of our Class A Common Stock issuable upon conversion of the
notes, to indemnify each other against certain liabilities arising under the
Securities Act.

     We agreed pursuant to the Registration Rights Agreement to use reasonable
efforts to cause the registration statement to which this prospectus relates to
become effective within 180 days after the date the notes were originally issued
and to keep the registration statement effective until the earlier of:

     - the sale of all the securities registered under the registration
       statement,

     - the expiration of the holding period applicable to the securities under
       Rule 144(k) under the Securities Act with respect to persons who are not
       our affiliates, and

     - two years from the date the registration statement is declared effective.

     The Registration Rights Agreement provides that we may suspend the use of
this prospectus in connection with sales of notes and shares of Class A Common
Stock issuable upon conversion of the notes by holders for a period not to
exceed an aggregate of 30 days in any 90-day period or 90 days in any 12-month
period if our Board of Directors shall determine it is in our best interests to
suspend such use. We will bear the expenses of preparing and filing the
registration statement and all post-effective amendments.

                                 LEGAL MATTERS
