   [LOGO]
                       AFFILIATED COMPUTER SERVICES, INC.
              4% CONVERTIBLE SUBORDINATED NOTES DUE MARCH 15, 2005
 
    This Prospectus relates to the offering for resale by the Selling
Securityholders (the "Selling Securityholders") of up to an aggregate of
$230,000,000 of 4% Convertible Subordinated Notes due March 15, 2005 (the
"Notes") of Affiliated Computer Services, Inc., a Delaware corporation ("ACS" or
the "Company"), and the 5,391,936 shares of Class A Common Stock, par value $.01
per share (the "Class A Common Stock") that are issuable upon conversion of the
Notes at the initial conversion rate of 23.4432 shares per U.S. $1,000 principal
amount of Notes, subject to adjustment in certain events. The Notes offered
hereby were originally offered by the Company in an underwritten private
placement.
 
    The Notes will be convertible at any time on or after June 15, 1998 and
prior to the close of business on the maturity date, unless previously redeemed
or repurchased, at a conversion rate of 23.4432 shares of Class A Common Stock
per $1,000 principal amount of Notes (equivalent to a conversion price of U.S.
$42.66 per share), subject to adjustment under certain circumstances. See
"Description of Notes -- Conversion Rights". The Company's Class A Common Stock
is listed on the New York Stock Exchange under the symbol "AFA." The closing
sale price of the Class A Common Stock on April 1, 1998 was $34 1/16 per share.
Interest on the Notes will be payable semiannually on March 15 and September 15
of each year, commencing on September 15, 1998.
 
    The Notes are redeemable at the option of the Company, on or after March 15,
2002, in whole or in part, at the redemption prices set forth herein, plus
accrued interest to the redemption date. See "Description of Notes -- Optional
Redemption". The Notes are not entitled to any sinking fund. The Notes will
mature on March 15, 2005.
 
    In the event of a Change in Control (as defined herein), each holder of
Notes may require the Company to repurchase its Notes, in whole or in part, for
cash or, at the Company's option, Class A Common Stock (valued at 95% of the
average closing sale prices for the five trading days immediately preceding and
including the third trading day prior to the repurchase date) at a repurchase
price of 100% of the principal amount of Notes to be repurchased, plus accrued
interest to the repurchase date. See "Description of Notes -- Repurchase at
Option of Holders Upon a Change in Control".
 
    The Notes are unsecured obligations of the Company, subordinated in right of
payment to all existing and future Senior Indebtedness (as defined herein) of
the Company and effectively subordinated in right of payment to all indebtedness
and other liabilities of the Company's subsidiaries. As of December 31, 1997,
the aggregate amount of outstanding Senior Indebtedness of the Company was
approximately $300 million. The Indenture will not restrict the Company or its
subsidiaries from incurring additional Senior Indebtedness or other
indebtedness. See "Description of Notes -- Subordination".
 
    The Notes may be sold from time to time pursuant to this Prospectus by the
Selling Securityholders. The Notes may be sold by the Selling Securityholders in
ordinary brokerage transactions, in transactions in which brokers solicit
purchases, in negotiated transactions, or in a combination of such methods of
sale, at market prices prevailing at the time of sale, at prices relating to
such prevailing market prices or at negotiated prices. See "Plan of
Distribution." The distribution of the Notes is not subject to any underwriting
agreement. The Company will receive no part of the proceeds of sales from the
offering by the Selling Securityholders. All expenses of registration incurred
in connection with this offering are being borne by the Company, but all selling
and all other expenses incurred by the Selling Securityholders will be borne by
such Selling Securityholders. None of the securities offered pursuant to this
Prospectus have been registered prior to the filing of the Registration

                                  RISK FACTORS
 
    In addition to the other information set forth in this Prospectus, the
following risk factors should be carefully considered in evaluating an
investment in the Notes offered hereby and the shares of Class A Common Stock
issuable upon conversion thereof. This Prospectus contains certain
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act, which involve risks and uncertainties.
The Company's actual results may differ significantly from the results discussed
in the forward-looking statements as a result of various risks and
uncertainties, including the timing and magnitude of technological advances; the
performance of recently acquired businesses; the prospects for future
acquisitions; the possibility that a current customer could be acquired or
otherwise affected by a future event that would diminish their information
technology requirements; the competition in the information technology industry
and the impact of such competition on pricing, revenues and margins; the degree
to which business entities continue to outsource information technology and
business processes; uncertainties surrounding budget reductions or changes in
funding priorities or existing government programs; the costs of attracting and
retaining highly skilled personnel; and the other factors summarized below.
 
RELIANCE ON SIGNIFICANT CUSTOMERS
 
    The success of ACS has been dependent in large part on its retention of
contracts with certain significant customers. The five largest customers of ACS
for the fiscal years ended June 30, 1995, 1996, and 1997, accounted for
approximately 21%, 23%, and 22%, respectively, of its revenues. For the fiscal
year ended June 30, 1997, the Company's principal contract with the Department
of Education accounted for approximately 11% of ACS's revenues. Other than the
Department of Education, no one customer represented more than 5% of ACS's
revenues for the fiscal year ended June 30, 1997. While ACS believes its
relations with such customers are good and has contracts with each with
remaining terms of approximately one to seven years, the loss of any of such
customers or a material decrease in services provided to any such customers
could have an adverse impact on ACS. Generally, ACS may lose customers due to
merger, business failure, conversion to a competing data processor, or
conversion to an in-house data processing system. There can be no assurance that
ACS will be able to maintain long-term relationships with its significant
customers. ACS could also be vulnerable to reduced processing volumes from its
customers, which reductions might occur due to business downturns, product
liability issues, work stoppages by organized labor, or other business reasons.
Many of ACS's customers are in industries that are currently undergoing
significant consolidation.
 
    Generally, the Company's business with the federal government is conducted
through Computer Data Systems, Inc., a Maryland corporation ("CDSI"). Such
business is subject to various risks, including the reduction or modification of
contracts due to changing government needs and requirements. Additionally, the
federal government may terminate contracts, including the Company's principal
contract with the Department of Education, for convenience. In the event of such
a termination of one or more of CDSI's contracts, CDSI would generally be
reimbursed for the then remaining unamortized costs incurred with respect to
providing the services under such contracts. See "-- Government Contracts".
 
    Outsourcing companies such as ACS incur a high level of fixed costs related
to data processing customers. These fixed costs result from significant
investments in data processing centers, including computer hardware platforms,
computer software, facilities, and customer service infrastructure. The loss of
any one significant outsourcing customer can leave an outsourcing company with a
higher level of fixed costs than is necessary to serve remaining customers,
thereby reducing profitability. ACS also incurs a high level of variable costs
related to its image management and professional services customers. Such
variable costs are primarily due to the labor intensive nature of providing
these services.
 
                                       3
<PAGE>
INVESTMENTS RELATED TO SIGNIFICANT CUSTOMER CONTRACTS
 
    Large outsourcing agreements often require a significant capital investment.
ACS is sometimes required to purchase certain assets (such as computing
equipment and purchased software), assume certain financial obligations (such as
computer lease and software maintenance obligations), make investments in
certain securities issued by its customers, incur specific capital expenditures
or incur expenses necessary to provide outsourcing services to a new customer.
These investments and asset purchases have been recorded by ACS at fair market
value, with the remainder of the purchase amount recorded as intangible assets,
which are then amortized over the term of each contract. The termination of a
customer contract or the deterioration of the financial condition of a customer
has in the past, and may in the future, result in an impairment of the net book
value of the assets recorded. Moreover, there can be no assurance that ACS will
be successful in its ability to both finance and properly evaluate these assets
and investments.
 
COMPETITION AND TECHNOLOGICAL CHANGE
 
    The markets for ACS's services are intensely competitive and highly
fragmented. ACS's market share represents a small percentage of the total
information processing market. Many of ACS's principal competitors have greater
financial, technical, and operating resources than ACS, and 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 the Company's largest competitors have greater international
presences than the Company and offer a broader range of services. In addition,
ACS's competitors are expected to continue their practice of investing in or
acquiring assets from large data processing customers in order to obtain
outsourcing contracts. There can be no assurance that ACS will be able to
compete successfully in the future or that competition will not have a material
adverse effect on the results of operations of ACS.
 
    The market for information processing services is subject to rapid
technological changes and rapid changes in customer requirements. Technological
advances and competition require ACS to commit substantial amounts of its
resources to the operation of multiple hardware platforms, the customization of
third-party software programs and the training of customer personnel in the use
of such hardware and software. A significant portion of ACS's outsourcing
revenue is derived from data processing services performed on IBM-compatible
mainframe systems. Technological advances currently in process may result in the
development of hardware and software products that are able to manipulate large
amounts of data more cost-effectively than existing mainframe platforms. An
acceleration of the shift towards client-server data processing, in which
individual computers or groups of personal computers and mid-range systems
replace mainframe systems, may adversely affect ACS. ACS has committed
substantial amounts of its resources to the development of outsourcing solutions
for these distributed computing environments. There can be no assurance that ACS
will be successful in customizing products and services that incorporate new
technology on a timely basis or will continue to be able to deliver the services
and products demanded by the marketplace.
 
RISKS RELATED TO THE COMPANY'S ACQUISITION STRATEGY
  AND POTENTIAL DIFFICULTIES IN MANAGING GROWTH AND EXPANSION
 
    A key element of the Company's strategy has been, and will continue to be,
to expand its business by strategic acquisitions of companies that enable the
Company to expand its geographic presence, to expand the products and services
offered to existing customers and to obtain a presence in new, complementary
markets. Since its inception in June 1988, ACS has completed 38 acquisitions
accounted for as purchases and one acquisition, its recent acquisition of CDSI,
accounted for as a pooling of interests. Approximately one-half of the increase
in the Company's revenues during the five years ended June 30, 1997 is
attributable to acquisitions accounted for as purchases. The Company regularly
evaluates potential acquisition candidates.
 
                                       4
<PAGE>
    No assurance can be given that the Company will be able to identify any
suitable acquisition candidates, to complete any acquisitions on favorable terms
or to obtain any financing that may be required on favorable terms, that any
acquisition by the Company will not adversely affect the business, financial
condition or results of operations of the Company or that acquisitions will
enhance the business of the Company. In pursuing acquisitions, the Company
competes with other companies, some of which have greater financial resources
than the Company. Without additional acquisitions, the Company's ability to
continue to grow at historical rates could be adversely affected. In addition,
as acquisition activity in the information technology services industry
continues, it may become increasingly difficult for the Company to find suitable
acquisition candidates on favorable terms.
 
    Acquisitions involve a number of risks that could adversely affect the
business, financial condition or results of operations of the Company, including
the diversion of management's attention, the assimilation of the operations and
personnel of the acquired companies and the potential loss of key employees. The
Company's ability to manage its growth effectively will require it to continue
to improve its corporate accounting, financial reporting and management
information systems, and to attract, retain, train, motivate and manage its
employees effectively.
 
    Acquisitions also entail transaction costs and integration expenses, in
addition to increased indebtedness and non-cash amortization charges in many
cases. Future acquisitions may result in potentially dilutive issuances of
securities and increased goodwill and intangible assets and amortization
expenses.
 
GOVERNMENT CONTRACTS
 
    After taking into account the recent acquisition of CDSI by ACS (which was
accounted for as a pooling of interests) approximately 33% of ACS's revenues in
fiscal 1997 were derived from contracts with the United States government or
agencies thereof (collectively, the "Government"). The Company, primarily,
through CDSI, has over 40 active prime contracts and numerous active
subcontracts with the Government, the largest of which accounted for
approximately 11% of the Company's revenues for fiscal 1997. Loss or termination
of one or more large Government contracts could have a material adverse effect
on the Company.
 
    Government contracts, by their terms, generally can be terminated for
convenience by the Government, which means that the Government may terminate the
contract at any time, without cause, and in certain instances ACS would be
entitled to receive compensation only for the services provided or costs
incurred at the time of termination. In addition, many of the Government
contracts awarded to the Company 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 option periods and its failure to exercise option periods could curtail
the contract term of certain contracts held by the Company. The Government's
termination of, or failure to exercise option periods for, significant
Government contracts could have a material adverse effect on the Company.
 
    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 any costs are improperly charged to a contract, the costs are not
reimbursable and, if already reimbursed, will have to be refunded to the
Government. Furthermore, if improper or illegal activities are discovered in the
course of any 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. The
Company believes that this high level of industry scrutiny will continue for the
foreseeable future. There can be no assurance that the Company will not be
subject in the
 
                                       5
<PAGE>
future to penalties and sanctions with respect to its activities, both past and
future. If the Company became subject to penalties or sanctions, the penalties
or sanctions could have a material adverse effect on the Company's business and
financial condition.
 
RISKS RELATED TO POTENTIAL YEAR 2000 PROBLEMS
 
    The Company utilizes a significant number of computer software programs and
operating systems across its entire organization. To the extent that the
Company's systems contain source codes that are unable to interpret
appropriately the upcoming calendar year 2000, some level of modification, or
even possibly replacement of such systems, may be necessary. The Company has
established processes for evaluating and managing the risks associated with Year
2000 software failures and management is in the process of taking steps to
ensure a smooth Year 2000 transition. The Company has identified and analyzed
both internally developed and acquired system software that utilizes date
embedded codes that may experience operational problems when the year 2000 is
reached. The Company is making and intends to complete necessary modifications
to the identified system software by the end of calendar year 1998. Management
does not anticipate that the Company will incur significant operating expenses
or be required to invest heavily in computer systems improvements to be Year
2000 compliant. However, no assurance can be given that any or all of the
Company's systems are or will be Year 2000 compliant or that the costs required
to address the Year 2000 issue or that the effect of the Company's failure to
achieve substantial Year 2000 compliance will not have a material adverse effect
on the Company's business, financial condition or results of operations.
 
    The Company is also cooperating with its customers, suppliers and others
with which it does business to coordinate Year 2000 compliance. In most
instances, the Company's customers maintain and enhance their own application
programs, although they use computer and network resources provided by the
Company. Although the Company generally does not have any contractual
responsibility to ensure that such application programs are Year 2000 compliant,
the Company's business could be adversely affected if the Company's customers
experience Year 2000 problems with such applications and such customers
consequently use less computing resources of the Company, alter their pattern of
usage of resources or dedicate less of their information processing budgets to
projects conducted by the Company. The Company's business could also be
adversely affected if potential new customers decide not to pursue outsourcing
projects as a result of focusing information technology resources on Year 2000
issues in their own organizations.
 
RISKS ASSOCIATED WITH ATM FEE LEGISLATION
 
    Legislation and regulations have been proposed at the state and federal
government levels that may be enacted to regulate the fees that may be collected
by ATM owners, which could have the effect of reducing the economic viability of
many ATMs. If such or similar legislation or regulations are enacted, the number
of ATMs operated nationwide (or within the geographic areas affected by the
legislation or regulations) could be significantly reduced. This could adversely
affect ACS's results of operations as it relates to ACS electronic commerce ("
ECG") business. Approximately 10% of ACS revenues for the fiscal year ended June
30, 1997 were derived from its ECG business.
 
DEPENDENCE ON KEY PERSONNEL
 
    The success of ACS is largely dependent on the skills, experience, and
performance of certain key members of its management, including Darwin Deason,
Chairman of the Board and Chief Executive Officer of ACS. The loss of the
services of any of these key employees could have an adverse effect on ACS's
business and prospects. ACS has not entered into employment agreements with any
of its key personnel, although it has entered into severance agreements with
each of its executive officers.
 
                                       6
<PAGE>
    The Company's success will also depend to a significant extent upon its
ability to continue to attract, retain and motivate highly skilled and qualified
personnel. Competition for such personnel is intense in the information
technology services industry.
 
VOTING CONTROL BY CHAIRMAN OF THE BOARD
 
    ACS is controlled by Darwin Deason, its Chairman and Chief Executive
Officer, who has voting control over an aggregate of 3,299,686 shares of Class B
Common Stock, par value $.01 per share ("Class B Common Stock"), of the Company
and 3,123,410 shares of Class A Common Stock, which have an aggregate of
36,120,270 votes, or approximately 46% of the total voting power of ACS.
Accordingly, Mr. Deason can significantly affect virtually all decisions made
with respect to ACS by its stockholders, including decisions relating to the
election of directors.
 
SUBORDINATION
 
    The Notes will be unsecured and subordinated in right of payment in full to
all existing and future Senior Indebtedness of the Company. As a result of such
subordination, in the event of the Company's liquidation or insolvency, payment
default with respect to Senior Indebtedness, or upon the acceleration of the
Notes due to an event of default, the assets of the Company will be available to
pay obligations on the Notes only after all Senior Indebtedness has been paid in
full, and there may not be sufficient assets remaining to pay amounts due on any
or all of the Notes then outstanding.
 
    The Notes are obligations exclusively of the Company. Since the operations
of the Company are partially conducted through subsidiaries, the cash flow and
the consequent ability to service debt, including the Notes, of the Company, are
partially dependent upon the earnings of its subsidiaries and the distribution
of those earnings to, or upon loans or other payments of funds by those
subsidiaries to, the Company. The payment of dividends and the making of loans
and advances to the Company by its subsidiaries are subject to statutory or
contractual restrictions, are dependent upon the earnings of those subsidiaries
and are subject to various business considerations. Any right of the Company to
receive assets of any of its subsidiaries upon their liquidation or
reorganization (and the consequent 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 the Company is itself recognized as a creditor of such subsidiary, in which
case the claims of the Company would still be subordinate to any security
interests in the assets of such subsidiary and any indebtedness of such
subsidiary senior to that held by the Company.
 
    As of December 31, 1997, the Company had approximately $300 million of
indebtedness and other liabilities that would have constituted Senior
Indebtedness. The Indenture does not prohibit or limit the incurrence of Senior
Indebtedness or the incurrence of other indebtedness or other liabilities by the
Company or its subsidiaries. The incurrence of additional indebtedness and other
liabilities by the Company or its subsidiaries could adversely affect the
Company's ability to pay its obligations on the Notes. See "Description of Notes
- -- Subordination".
 
LIMITATIONS ON REPURCHASE OF NOTES
 
    The Company's ability to repurchase Notes upon the occurrence of a Change in
Control is subject to limitations. There can be no assurance that the Company
would have the financial resources, or would be able to arrange financing, to
pay the repurchase price for all the Notes that might be delivered by Holders of
Notes seeking to exercise the repurchase right. Moreover, although under the
Indenture the Company may elect, subject to satisfaction of certain conditions,
to pay the repurchase price for the Notes using shares of Class A Common Stock,
the terms of the 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 equity of the Company that is not mandatorily
redeemable and up to $3 million in cash redemptions) and
 
                                       7
<PAGE>
the Company's ability to repurchase Notes may be limited or prohibited by the
terms of borrowing arrangements, including Senior Indebtedness, existing at the
time of a Change in Control. The Company's ability to repurchase Notes may also
be limited by the terms of its subsidiaries' then-existing borrowing
arrangements due to dividend restrictions. Any failure by the Company to
repurchase the Notes when required following a Change in Control would result in
an Event of Default under the Indenture whether or not such repurchase is
permitted by the subordination provisions of the Indenture. Any such default
may, in turn, cause a default under Senior Indebtedness of the Company.
Moreover, the occurrence of a Change in Control could result in an event of
default under the Credit Facility and may cause an event of default under the
terms of other Senior Indebtedness of the Company. As a result, in each case,
any repurchase of the Notes would, absent a waiver, be prohibited under the
subordination provisions of the Indenture until the Senior Indebtedness is paid
in full. In addition, the Company's repurchase of the Notes as a result of the
occurrence of a Change in Control may be prohibited or limited by, or create an
event of default under, the terms of agreements related to borrowings which the
Company may enter into from time to time, including agreements relating to
Senior Indebtedness. See "Description of Notes -- Repurchase at Option of
Holders Upon a Change in Control".
 
ABSENCE OF TRADING MARKET; TRANSFER RESTRICTIONS
 
    There is no existing trading market for the Notes and there can be no
assurance as to the liquidity of any such market that may develop, the ability
of the holders of Notes to sell such securities, the price at which the holders
of Notes would be able to sell such securities or whether a trading market, if
it develops, will continue. The Notes are expected to be eligible for trading in
the Private Offerings, Resales and Trading through Automated Linkages market of
the National Association of Securities Dealers, Inc. ("NASD"). The Company does
not intend to apply for listing of the Notes on any securities exchange or for
inclusion of the Notes on any automated quotation system. If a liquid market for
the Notes fails to develop or be maintained, the trading price of the Notes
could be adversely affected. If a trading market were to develop, the Notes
could trade at prices higher or lower than their principal amount, depending
upon many factors, including prevailing interest rates, the market for similar
securities and the operating results of the Company.
 
    Transfers of Notes and Class A Common Stock issuable upon conversion of the
Notes are subject to certain restrictions. Each purchaser of Notes offered
hereby in making its purchase will be deemed to have made certain
acknowledgments, representations and agreements with respect to such transfer
restrictions.
 
POTENTIAL VARIABILITY OF OPERATING RESULTS; POSSIBLE PRICE VOLATILITY
 
    The Company's future operating results are uncertain and can vary from
quarter to quarter and from year to year due to fluctuations in a wide variety
of factors, many of which are outside of the Company's control, including, but
not limited to, the timing and magnitude of technological advances, the
possibility that a current customer could be acquired or otherwise affected by a
future event that would diminish their information technology requirements,
competition in the information technology industry and the impact of such
competition on pricing, revenues and margins, the degree to which business
entities continue to outsource information and business processes, uncertainties
surrounding budget reductions or changes in funding priorities or existing
government programs and general economic factors. Unfavorable changes in the
above or other factors could adversely affect the Company's operating results in
any period.
 
    The price of Class A Common Stock is determined in the marketplace and may
be influenced by many factors, including the depth and liquidity of the market
for the Class A Common Stock, investor perception of ACS and the industry within
which ACS competes and general economic and market conditions. Variations in
operating results, general trends in the industry and other factors could cause
the market price of the Class A Common Stock to fluctuate significantly. In
addition, general trends and developments in the industry, including the
announcement of technological innovations by ACS or its competitors, government
regulation and other factors, could have a significant impact on the price of
Class A Common
 
                                       8
<PAGE>
Stock. The stock market has, on occasion, experienced extreme price and volume
fluctuations that have often particularly affected market prices for smaller
companies and that often have been unrelated or disproportionate to the
operating performance of the affected companies, and the price of Class A Common
Stock could be affected by such fluctuations.
 
ANTI-TAKEOVER EFFECT OF CERTIFICATE OF INCORPORATION AND BYLAWS AND OTHER
  STOCKHOLDER
  PROTECTION MECHANISMS
 
    Certain provisions of the ACS charter and ACS bylaws may delay, defer, or
prevent a tender offer or takeover attempt that a stockholder might consider to
be in such stockholder's best interest, including attempts that might result in
a premium over the market price for the securities. For example, the ACS charter
provides that the removal of any director or directors, with or without cause,
requires the affirmative vote of at least 80% of the combined voting stock of
ACS, giving effect to the number of votes per share attributable to such share.
Such ACS charter provision would restrict the ability of a party to gain control
of the ACS Board by acquiring a majority of the ACS voting stock, removing all
of the directors and then replacing them with directors seeking to benefit such
party. Additionally, the ACS bylaws provide that the number of directors shall
be fixed, from time to time, by resolution of the ACS Board, and further, that
such number of directors of ACS be divided into three classes that are elected
for staggered three-year terms. Thus, in any given year, only a portion of the
ACS directors would be eligible for election, thereby eliminating the ability of
a hostile party to gain control of the ACS Board in a single proxy contest,
making an unsolicited takeover attempt (including an attempt that an ACS
stockholder might consider in such stockholders' best interest) more expensive
and more difficult. The ACS bylaws also provide for advance notice procedures
with respect to the submission by stockholders of proposals to be acted on at
stockholder meetings and of nominations of candidates for election as directors.
Further, the ACS charter permits the ACS Board to establish by resolution one or
more series of preferred stock ("ACS Preferred Stock") and to establish the
powers, designations, preferences and relative, participating, optional, or
other special rights of each series of ACS Preferred Stock. The ACS Preferred
Stock could be issued on terms that are unfavorable to the holders of Class A
Common Stock or that could make a takeover or change in control of ACS more
difficult. The Company also has a significant number of authorized but unissued
shares of Class B Common Stock, which are entitled to ten votes per share. The
issuance of shares of Class B Common Stock could make a takeover or change in
control of ACS more difficult. Further, ACS has instituted a stockholder rights
plan and has entered into severance agreements with each of its executive
officers, which plan and agreements may have the effect of discouraging an
unsolicited takeover proposal. Moreover, ACS is subject to Section 203 of the
Delaware General Corporation Law, which places restrictions on certain business
combinations with certain stockholders that could render more difficult a change
in control of ACS. Finally, the ownership by Mr. Deason of approximately 46% of
the total voting power of ACS capital stock, including shares of Class B Common
Stock that are entitled to ten votes per share, could also have the effect or
delaying, deterring or preventing a takeover of ACS. See "-- Voting Control by
Chairman of the Board."
 
SHARES AVAILABLE FOR FUTURE SALE
 
    No prediction can be made as to the effect, if any, that future sales of
Notes or shares of Class A Common Stock or the availability of Notes, shares of
Class A Common Stock or shares of Class B Common Stock for future sale, will
have on the market price of Class A Common Stock prevailing from time to time.
Sales of substantial amounts of Class A Common Stock (including shares issued
upon the exercise of stock options) or Class B Common Stock, or the perception
that such sales could occur, may adversely affect prevailing market prices for
Class A Common Stock. In connection with a recent acquisition, the Company
agreed to file with the Commission under certain circumstances a registration
statement including up to 304,086 shares of Class A Common Stock. In addition,
in connection with the initial public offering of the Company's Class A Common
Stock, the Company filed with the Commission a shelf registration statement,
which has not been withdrawn and currently covers 14,811,812 shares.

    The Company and the directors and executive officers of the Company have
agreed that until after June 15, 1998, they will not, directly or indirectly,
offer, sell, contract to sell or otherwise dispose of any shares of Class A
Common Stock (other than the issuance of Class A Common Stock upon conversion of
the Notes), any shares of Class B Common Stock, any securities substantially
similar to the Notes, the Class A Common Stock or the Class B Common Stock or
any securities convertible into or exchangeable or exercisable for Class A
Common Stock or substantially similar securities (other than, in the case of the
Company, pursuant to existing employee stock option and stock purchase plans,
upon the conversion of outstanding convertible securities or pursuant to
existing earn-out obligations arising out of prior acquisitions), without the
prior consent of Goldman, Sachs & Co.; provided, however, that the Company may
issue up to 3,000,000 shares of Class A Common Stock in consideration for
acquisitions of businesses occurring after March 17, 1998 but before June 15,
1998, provided that each recipient of any such shares agrees in writing that all
such shares shall remain subject to restrictions identical to those contained in
this sentence; and provided, further, however, that during the period beginning
on April 17, 1998 continuing to and including June 15, 1998, the directors and
executive officers may offer, sell, contract to sell or otherwise dispose of up
to an aggregate of 12.5% of their individual holdings of shares of Class A
Common Stock and Class B Common Stock.

                              DESCRIPTION OF NOTES
 
    The Notes have been issued under an Indenture, dated as of March 20, 1998
(the "Indenture"), between the Company and U.S. Trust Company, as Trustee (the
"Trustee"), copies of which are available for inspection at the Corporate Trust
Office of the Trustee in the Borough of Manhattan, The City of New York.
Wherever particular defined terms of the Indenture (including the Notes and the
various forms thereof) are referred to, such defined terms are incorporated
herein by reference (the Notes and various terms relating to the Notes being
referred to in the Indenture as "Securities"). References in this section to the
"Company" are solely to Affiliated Computer Services, Inc. and not its
subsidiaries. The following summaries of certain provisions of the Indenture do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, the detailed provisions of the Notes and the
Indenture, including the definitions therein of certain terms.
 
GENERAL
 
    The Notes are unsecured subordinated obligations of the Company, are limited
to U.S.$230,000,000 aggregate principal amount and mature on March 15, 2005,
payable at a price of 100% of the principal amount thereof. The Notes bear
interest at the rate per annum shown on the front cover of this Prospectus from
March 20, 1998, payable semiannually on March 15 and September 15 of each year,
commencing on September 15, 1998. Interest payable per $1,000 principal amount
of Notes for the period from March 20, 1998 to September 15, 1998 will be
U.S.$19.44.
 
    The Notes are convertible into Class A Common Stock initially at the
conversion rate stated on the cover page hereof, subject to adjustment upon the
occurrence of certain events described under "-- Conversion Rights", at any time
on or after the 90th day following the last original issue of the Notes and
prior to the close of business on the maturity date, unless previously redeemed
or repurchased.
 
    The Notes are redeemable at the option of the Company, on or after March 15,
2002, in whole or in part, at the redemption prices set forth below under "--
Optional Redemption", plus accrued interest to the redemption date.
 
GLOBAL NOTE; BOOK-ENTRY SYSTEM
 
    Notes held by Qualified Institutional Buyers as defined in Rule 144A under
the Securities Act (each a "Qualified Institutional Buyer"), or by non-U.S.
persons who acquired Notes in an "offshore transaction" in reliance on
Regulation S under the Securities Act (each a "Non-U.S. Person"), are evidenced
by one or more global Notes in definitive, fully registered form without
interest coupons (collectively, the "Global Note"), which will be 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 Note (and any
Notes issued in exchange therefor) will be subject to certain restrictions on
transfer set forth therein and in the Indenture and will bear a legend regarding
such restrictions. Except as set forth below, record ownership of the 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.
 
    Qualified Institutional Buyers and Non-U.S. Persons may beneficially own
interests in the Global Note held by DTC only through participants in DTC
("Participants") or certain banks, brokers, dealers, trust companies and other
parties that clear through or maintain a custodial relationship with a
Participant either directly or indirectly ("Indirect Participants"). A Qualified
Institutional Buyer and Non-U.S. Person may hold its interest in the Global Note
directly through DTC if such Qualified Institutional Buyer is a participant in
DTC or indirectly through organizations that are Participants. Transfers between
Participants will be effected in the ordinary way in accordance with DTC's rules
and will be settled in same-day funds. The laws of some states require that
certain persons take physical delivery of securities in definitive form.
Consequently, the ability to transfer beneficial interests in the Global Note to
such persons may be limited.
 
                                       14
<PAGE>
    Cash payment of interest on and principal of and the redemption or
repurchase of the Global Note, as well as any payment of Liquidated Damages,
will be made to Cede, the nominee for DTC, as the registered owner of the Global
Note, by wire transfer of immediately available funds on each relevant payment
date. Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the Global Note, including for any delay by
DTC or any Participant or Indirect Participant in identifying the beneficial
ownership interests, and the Company and the Trustee may conclusively rely on,
and shall be protected in relying on, instructions from DTC for all purposes.
 
    The Company has been informed that, with respect to any cash payment of
interest on, principal of, or the redemption or repurchase price of, the Global
Note, as well as any payment of Liquidated Damages, DTC's practice is to credit
Participants' accounts on the payment date therefor with payments in amounts
proportionate to their respective beneficial interests in the Notes represented
by the Global Note as shown on the records of DTC (adjusted as necessary so that
such payments are made with respect to whole Notes only), unless DTC has reason
to believe that it will not receive payment on such payment date. Payments by
Participants to owners of beneficial interests in Notes represented by the
Global Note held through such Participants will be the responsibility of such
Participants, as is now the case with securities held for the accounts of
customers registered in "street name".
 
    Redemption notices shall be sent to Cede. 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 in such issue to be redeemed.
 
    Neither DTC or Cede will consent or vote with respect to the Notes. Under
its usual procedures, DTC mails an omnibus proxy (the "Omnibus Proxy") to the
issuer 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 the Global Note to pledge such
interest to persons or entities that do not participate in the DTC book-entry
system, or otherwise take actions in respect of such interest, may be affected
by the lack of a physical certificate evidencing such interest.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more Participants to whose
account with DTC interests in the Global Note are credited and only in respect
of such portion of the principal amount of the Notes represented by the Global
Note as to which such Participant or Participants has or have given such
direction.
 
    DTC has advised the Company 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, thereby eliminating the need for
physical transfer and delivery of certificates. 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 rules applicable to DTC and its
Participants are on file with the Commission.
 
                                       15
<PAGE>
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of beneficial ownership interests in the Global Note among
Participants, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time.
 
    The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Company believes to be reliable, but the
Company takes no responsibility for the accuracy thereof. None of the Company,
the Trustee nor any of their respective agents will have any responsibility for
the performance by DTC, its Participants or Indirect Participants of their
respective obligations under the rules and procedures governing their
operations, including maintaining, supervising or reviewing the records relating
to, or payments made on account of, beneficial ownership interests in the Global
Note.
 
    So long as DTC, or its nominee, is the registered owner of the Global Note,
DTC or its nominee, as the case may be, will be considered the sole legal owner
or holder of the Notes represented by the Global Note for all purposes under the
Indenture. Except as set forth below, owners of beneficial interests in such
Global Note will not be entitled to have Notes represented by the Global Note
registered in their names, will not receive or be entitled to receive physical
delivery of Notes in definitive form and will not be considered the legal owners
or holder thereof under the Indenture. Accordingly, each person owning a
beneficial interest in the Global Note must rely on the procedures of DTC and,
if such person is not a Participant, those of the Participant through which such
person owns its interests, in order to exercise any rights of a holder under the
Indenture or such Note.
 
    If DTC is at any time unwilling, unable or ineligible to continue as
depository and a successor depository is not appointed by the Company within 90
days, the Company will issue Notes in definitive registered form, without
coupons, in denominations of U.S. $1,000 of principal amount at maturity and any
integral multiple thereof, in exchange for the Global Note representing such
Notes. In addition, the Company may at any time and in its sole discretion
determine not to have any Notes in registered form represented by the Global
Note and, in such event, will issue Notes in definitive registered form, without
coupons, in exchange for the Global Note representing such Notes. In any such
instance, an owner of a beneficial interest in the Global Note will be entitled
to physical delivery in definitive form of Notes represented by such Global Note
equal in principal amount to such beneficial interest and to have such Notes
registered in its name.
 
CONVERSION RIGHTS
 
    The Holder of any Note will have the right, at the Holder's option, to
convert any portion of the principal amount of any Note that is an integral
multiple of $1,000 into shares of Class A Common Stock at any time on or after
the 90th day following the last original issue date of the Notes and prior to
the close of business on the maturity date, unless previously redeemed or
repurchased, at a conversion rate of 23.4432 shares of Class A Common Stock per
$1,000 principal amount of Notes (the "Conversion Rate") (equivalent to a
conversion price of $42.66 per share of Class A Common Stock), subject to
adjustment in certain events as described below. The right to convert a Note
called for redemption or delivered for repurchase will terminate at the close of
business on the Redemption Date for such Note or the Repurchase Date, as the
case may be.
 
    The right of conversion attaching to any Note may be exercised by the Holder
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. Such notice of conversion can be obtained at the
office of the Trustee at its Corporate Trust Office in New York City. 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, the Company will issue and deliver to the Trustee
a certificate or certificates for the number of full shares of Class A Common
Stock issuable upon conversion, together with payment in lieu of any fraction of
a share; such certificate will be sent by
 
                                       16
<PAGE>
the Trustee to the Conversion Agent for delivery to the Holder. Such shares of
Class A Common Stock issuable upon conversion of the Notes, in accordance with
the provisions of the Indenture, will be fully paid and nonassessable and will
rank PARI PASSU with the other shares of Class A Common Stock of the Company
outstanding from time to time. 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 a
Repurchase Date and, as a result, the right to convert such Notes 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 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 such Note on such Regular Record Date. As a
result of the foregoing provisions, Holders that surrender Notes for conversion
on a date that is not an Interest Payment Date will not receive any interest for
the period from the Interest Payment Date next preceding the date of conversion
to the date of conversion or for any later period, even if the Notes are
surrendered after a notice of redemption (except for the payment of interest on
Notes called for redemption on a Redemption Date or to be repurchased on a
Repurchase Date for which the right to convert such Notes would terminate
between a Regular Record Date and the Interest Payment Date to which it
relates). No other payment or adjustment for interest, or for any dividends in
respect of Class A Common Stock, will be made upon conversion. Holders of Class
A Common Stock issued upon conversion will not be entitled to receive any
dividends payable to holders of Class A Common Stock as of any record time or
date before the close of business on the conversion date. No fractional shares
will be issued upon conversion but, in lieu thereof, an appropriate amount will
be paid in cash by the Company based on the market price of the Class A Common
Stock at the close of business on the day of conversion.
 
    A Holder delivering a Note for conversion will not be required to pay any
taxes or duties in respect of the issue or delivery of Class A Common Stock on
conversion but will be required to pay any tax or duty which may be payable in
respect of any transfer involved in the issue or delivery of the Class A Common
Stock in a name other than that of the Holder of the Note. Certificates
representing shares of Class A Common Stock will not be issued or delivered
unless all taxes and duties, if any, payable by the Holder have been paid.
 
    The Conversion Rate is subject to adjustment in certain events, including,
without duplication: (a) dividends (and other distributions) payable in Class A
Common Stock on shares of capital stock of the Company, (b) the issuance to all
holders of Class A Common Stock of rights', options or warrants entitling them
to subscribe for or purchase 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, (c) subdivisions, combinations and
reclassifications of Class A Common Stock, (d) distributions to all holders of
Class A Common Stock of evidences of indebtedness of the Company, 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 to which the next succeeding paragraph applies), (e)
distributions consisting exclusively of cash (excluding any cash portion of
distributions referred to in (d) above, or cash distributed upon a merger or
consolidation to which the next succeeding paragraph applies) to all holders of
Class A Common Stock in an aggregate amount that, combined together with (i)
other such all-cash distributions made within the preceding 12 months in respect
of which no adjustment has been made and (ii) any cash and the fair market value
of other consideration payable in respect of any tender offer by the Company or
any of its subsidiaries for Class A Common Stock concluded within the preceding
12 months in respect of which no adjustment has been made, exceeds 10% of the
Company's 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 (f) the
successful completion of a tender offer
 
                                       17
<PAGE>
made by the Company or any of its subsidiaries for Class A Common Stock which
involves an aggregate consideration that, together with (i) any cash and other
consideration payable in a tender offer by the Company or any of its
subsidiaries for Class A Common Stock expiring within the 12 months preceding
the expiration of such tender offer in respect of which no adjustment has been
made and (ii) the aggregate amount of any such all-cash distributions referred
to in (e) above to all holders of Class A Common Stock within the 12 months
preceding the expiration of such tender offer in respect of which no adjustments
have been made, exceeds 10% of the Company's market capitalization on the
expiration of such tender offer. The Company reserves the right to make such
increases in the Conversion Rate in addition to those required in the foregoing
provisions as it considers 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. No adjustment of the Conversion Rate will
be required to be made until the cumulative adjustments amount to 1.0% or more
of the Conversion Rate. The Company will compute any adjustments to the
Conversion Rate pursuant to this paragraph and will give notice by mail to
Holders of the Registered Notes of any adjustments.
 
    In case of any consolidation or merger of the Company with or into another
Person or any merger of another Person into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or
cancellation of the Class A Common Stock), or in case of any sale or transfer of
all or substantially all of the assets of the Company, each Note then
outstanding will, without the consent of the Holder of any Note, 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 such Note was convertible
immediately prior thereto (assuming such holder of Class A Common Stock failed
to exercise any rights of election and that such Note was then convertible).
 
    In the event that the Rights are separated from the Class A Common Stock in
accordance with the provisions of the Company's Rights Agreement dated August
11, 1997 (the "Rights Agreement") such that the holder of Notes would thereafter
not be entitled to receive any such Rights in respect of the Class A Common
Stock issuable upon conversion of such Notes, the Conversion Rate will be
adjusted as provided in clause (b) of the preceding paragraph (subject to
readjustment in the event of an adjustment to the Purchase Price (as defined in
the Rights Agreement) or in the event of the expiration, termination or
redemption of the Rights). In lieu of any such adjustment, the Company may amend
the Rights Agreement to provide that upon conversion of the Notes the Holders
will receive, in addition to the Class A Common Stock issuable upon such
conversion, the Rights that would have attached to such shares of Class A Common
Stock if the Rights had not become separated from the Class A Common Stock
pursuant to the provisions of the Rights Agreement.
 
    The Company from time to time may increase the Conversion Rate by any amount
for any period of at least 20 days, in which case the Company shall give at
least 15 days' notice of such increase, if the Board of Directors has made a
determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. No such increase shall be taken into
account for purposes of determining whether the closing sale price of the Class
A Common Stock exceeds the Conversion Price by 105% in connection with an event
which otherwise would be a Change in Control.
 
SUBORDINATION
 
    The payment of the principal of, premium, if any, and interest on the Notes
(including any Liquidated Damages (as defined) and any amounts payable upon the
redemption or the repurchase of the Notes permitted by the Indenture) will be
subordinated in right of payment to the extent set forth in the Indenture to the
prior payment in full of the principal of, premium, if any, interest and other
amounts in respect of all Senior Indebtedness of the Company. The principal
amount of outstanding Senior Indebtedness was approximately $300 million at
December 31, 1997.
 
                                       18
<PAGE>
    "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: (a) indebtedness of the Company evidenced by a credit or loan
agreement, note, bond, debenture or other written obligation, (b) all
obligations of the Company for money borrowed, (c) all obligations of the
Company evidenced by a note or similar instrument given in connection with the
acquisition of any businesses, properties or assets of any kind, (d) obligations
of the Company (i) as lessee under leases required to be capitalized on the
balance sheet of the lessee under generally accepted accounting principles and
(ii) as lessee under other leases for facilities, capital equipment or related
assets, whether or not capitalized, entered into or leased for financing
purposes, (e) all obligations of the Company under interest rate and currency
swaps, caps, floors, collars, hedge agreements, forward contracts or similar
agreements or arrangements, (f) all obligations of the Company with respect to
letters of credit, bankers' acceptances and similar facilities (including
reimbursement obligations with respect to the foregoing), (g) all obligations of
the Company 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), (h) all obligations of the type referred to
in clauses (a) through (g) above of another Person and all dividends of another
Person, the payment of which, in either case, the Company has assumed or
guaranteed, or for which the Company is responsible or liable, directly or
indirectly, jointly or severally, as obligor, guarantor or otherwise, or which
is secured by a lien on the property of the Company, and (i) renewals,
extensions, modifications, replacements, restatements and refundings of, or any
indebtedness or obligation issued in exchange for, any such indebtedness or
obligation described in clauses (a) through (h) of this paragraph; provided,
however, that Senior Indebtedness shall not include the Securities or any such
indebtedness or obligation if the terms of such indebtedness or obligation (or
the terms of the instrument under which, or pursuant to which it is issued)
expressly provide that such indebtedness or obligation is not superior in right
of payment to the Securities.
 
    No payment on account of principal of, premium, if any, or interest on
(including any Liquidated Damages (as defined)), or the redemption or repurchase
of, the Notes may be made by the Company if (i) a default in the payment of
principal, premium, if any, or interest (including a default under any
repurchase or redemption obligation) or other amounts with respect to Senior
Indebtedness occurs and is continuing beyond the applicable grace period or (ii)
any other event of default occurs and is continuing with respect to Designated
Senior Debt (as defined below) that permits the holders thereof to accelerate
the maturity thereof, and the Trustee receives a notice of such default (a
"Payment Blockage Notice") from the Company, a holder of such Designated Senior
Debt or other person permitted to give such notice under the Indenture. Payments
on the Notes may and shall be resumed (a) in the case of a payment default, upon
the date on which such default is cured or waived and (b) in the case of a
nonpayment default, the earlier of the date on which such nonpayment default is
cured or waived or 179 days after the date on which the Payment Blockage Notice
is received. No new period or payment blockage may be commenced unless and until
(i) 365 days have elapsed since the effectiveness of the immediately prior
Payment Blockage Notice and (ii) all scheduled payments of principal, premium,
if any, and interest on the Notes that have come due have been paid in full in
cash. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for any subsequent Payment Blockage Notice. "Designated Senior Debt" means
the Company's obligations under the Credit Facility and 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 the
Company is a party) expressly provides that such indebtedness shall be
"Designated Senior Debt" for purposes of the Indenture (provided that such
instrument, agreement or other document may place limitations and conditions on
the right of such Senior Indebtedness to exercise the rights of Designated
Senior Debt). In addition, upon any acceleration of the principal due on the
Notes as
 
                                       19
<PAGE>
a result of an Event of Default or payment or distribution of assets of the
Company to creditors upon any dissolution, winding up, liquidation or
reorganization, whether voluntary or involuntary, marshaling of assets,
assignment for the benefit of credits, or in bankruptcy, insolvency,
receivership or other similar proceedings of the Company, all principal,
premium, if any, interest and other amounts due on all Senior Indebtedness must
be paid in full before the Holders of the Notes are entitled to receive any
payment. By reason of such subordination, in the event of insolvency, creditors
of the Company who are holders of Senior Indebtedness may recover more, ratably,
than the Holders of the Notes, and such subordination may result in a reduction
or elimination of payments to the Holders of the Notes.
 
    In addition, the Notes will be structurally subordinated to all indebtedness
and other liabilities (including trade payables and lease obligations) of the
Company's subsidiaries, as any right of the Company to receive any assets of its
subsidiaries upon their liquidation or reorganization (and the consequent 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 the Company itself is recognized as a
creditor of such subsidiary, in which case the claims of the Company would still
be subordinate to any security interest in the assets of such subsidiary and any
indebtedness of such subsidiary senior to that held by the Company.
 
    The Indenture does not limit the Company's or its subsidiaries' ability to
incur Senior Indebtedness or any other indebtedness.
 
OPTIONAL REDEMPTION
 
    The Notes may not be redeemed at the option of the Company prior to March
15, 2002. On and after March 15, 2002, the Notes may be redeemed, in whole or in
part, at the option of the Company, at the redemption prices specified below,
upon not less than 30 nor more than 60 days' prior notice as provided under "--
Notices" below.
 
    The redemption price (expressed as a percentage of principal amount) is as
follows for the 12-month periods beginning on March 15 of the following years:

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.
 
PAYMENT AND CONVERSION
 
    The principal of Notes will be payable in U.S. dollars, against surrender
thereof at the Corporate Trust Office of the Trustee in the Borough of
Manhattan, The City of New York, by dollar check drawn on, or by transfer to a
dollar account (such transfer to be made only to Holders of an aggregate
principal amount of Notes in excess of U.S.$2,000,000) maintained by the Holder
with, a bank in New York City. Payment of any installment of interest on Notes
will be made to the Person in whose name such Notes (or any predecessor Note) is
registered at the close of business on the March 1 or the September 1 (whether
or not a Business Day) immediately preceding the relevant Interest Payment Date
(a "Regular Record Date"). Payments of such interest will be made by a dollar
check drawn on a bank in New York City mailed to the Holder at such Holder's
registered address or, upon application by the Holder thereof to the Trustee not
later than the applicable Regular Record Date, by transfer to a dollar account
(such transfer to be made only to Holders of an aggregate principal amount of
Notes in excess of U.S.$2,000,000) maintained by the
 
                                       20
<PAGE>
Holder with a bank in New York City. No transfer to a dollar account will be
made unless the Trustee has received written wire instructions not less than 15
days prior to the relevant payment date.
 
    Payments in respect of the principal of (and premium, if any) and interest
on any Registered 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, the
Company and the Trustee will treat the Persons in whose names the Notes,
including the Registered Global Notes, are registered as the owners thereof for
the purpose of receiving such payments and for any and all other purposes
whatsoever. Consequently, neither the Company, the Trustee nor any agent of the
Company or the Trustee has or will have any responsibility or liability for (i)
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 the Registered Global Notes, 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 the Registered Global
Notes, or (ii) any other matter relating to the actions and practices of DTC or
any of its Participants or Indirect Participants.
 
    Any payment on the Notes due on any day which is not a Business Day need not
be made on such day, but may be made on the next succeeding Business Day with
the same force and effect as if made on such due date, and no interest shall
accrue on such payment for the period from and after such date. "Business Day",
when used with respect to any place of payment, place of conversion or any other
place, as the case may be, means each Monday, Tuesday, Wednesday, Thursday and
Friday which is not a day on which banking institutions in such place of
payment, place of conversion or other place, as the case may be, are authorized
or obligated by law or executive order to close; provided, however, that a day
on which banking institutions in New York, New York or London, England are
authorized or obligated by law or executive order to close shall not be a
Business Day for certain purposes.
 
    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".
 
    The Company has initially appointed the Trustee as Paying Agent and
Conversion Agent. The Company may at any time terminate the appointment of any
Paying Agent or Conversion Agent and appoint additional or other Paying Agents
and Conversion Agents, provided that 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 the Company as provided in the Indenture, it 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 such 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
the Company, 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 such
payment has become due and payable will be repaid to the Company, and the Holder
of such Note will thereafter look only to the Company for payment thereof.
 
REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE IN CONTROL
 
    If a Change in Control (as defined) occurs, each Holder of Notes shall have
the right, at the Holder's option, to require the Company to repurchase all of
such Holder's Notes not theretofore called for redemption, or any portion of the
principal amount thereof, that is $5,000 or an integral multiple of $1,000 in
excess thereof, on the date (the "Repurchase Date") that is 45 days after the
date of the Company Notice (as defined), at a price equal to 100% of the
principal amount of the Notes to be repurchased, together with interest accrued
to the Repurchase Date (the "Repurchase Price").
 
                                       21
<PAGE>
    The Company may, at its option, in lieu of paying the Repurchase Price in
cash, pay the Repurchase Price in Class A Common Stock valued at 95% of the
average of the closing sales prices of the Class A Common Stock for the five
trading days immediately preceding and including the third day prior to the
Repurchase Date; provided that payment may not be made in Class A Common Stock
unless the Company satisfies certain conditions with respect to such payment
prior to the Repurchase Date as provided in the Indenture.
 
    Within 30 days after the occurrence of a Change in Control, the Company is
obligated to give to all Holders of the Notes notice, as provided in the
Indenture (the "Company Notice"), of the occurrence of such Change in Control
and of the repurchase right arising as a result thereof. The Company must also
deliver a copy of the Company 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 the Company Notice irrevocable written notice to the Trustee of the Holder's
exercise of such right, together with the Notes with respect to which the right
is being exercised.
 
    A Change in Control shall be deemed to have occurred at such time after the
original issuance of the Notes as there shall occur:
 
        (i) the acquisition by any Person (including any syndicate or group
    deemed to be a "person" under Section 13(d)(3) of the Exchange Act) of
    beneficial ownership, directly or indirectly, through a purchase, merger or
    other acquisition transaction or series of transactions, of shares of
    capital stock of the Company entitling such Person to exercise 50% or more
    of the total voting power of all shares of capital stock of the Company
    entitled to vote generally in elections of directors, other (A) than any
    such acquisition by the Company, any subsidiary of the Company or any
    employee benefit plan of the Company or (B) 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
 
        (ii) any consolidation or merger of the Company with or into, any other
    Person, any merger of another Person into the Company, or any conveyance,
    sale, transfer or lease of all or substantially all of the assets of the
    Company to another Person (other than (a) any such transaction (x) which
    does not result in any reclassification, conversion, exchange or
    cancellation of outstanding shares of capital stock of the Company and (y)
    pursuant to which the holders of the 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 and (b) any merger which is
    effected solely to change the jurisdiction of incorporation of the Company
    and results in a reclassification, conversion or exchange of outstanding
    shares of Common Stock into solely shares of common stock);
 
provided, however, that a Change in Control shall not be deemed to have occurred
if the closing sales price per share of the 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 under clause (i) above) or
the period of 10 consecutive trading days ending immediately before the Change
in Control (in the case of a Change in Control under clause (ii) above) shall
equal or exceed 105% of the Conversion Price of the Notes in effect on each such
trading day. The "Conversion Price" is equal to $1,000 divided by the Conversion
Rate. "Beneficial Owner" shall be determined in accordance with Rule 13d-3
promulgated by the Commission under the Exchange Act, as in effect on the date
of execution of the Indenture. "Person" includes any syndicate or group which
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 certain
information to security holders in the event of an issuer tender offer and may
apply in the event that the repurchase option
 
                                       22
<PAGE>
becomes available to Holders of the Notes. The Company will comply with this
rule to the extent applicable at that time.
 
    The Company may, to the extent permitted by applicable law, at any time
purchase Notes in the open market or by tender at any price or by private
agreement. Any Note so purchased by the Company may, to the extent permitted by
applicable law and subject to restrictions contained in the Purchase Agreement,
be re-issued or resold or may, at the Company's option, be surrendered to the
Trustee for cancellation. Any Notes surrendered as aforesaid may not be
re-issued or resold and will be canceled promptly.
 
    The foregoing provisions would not necessarily afford Holders of the Notes
protection in the event of highly leveraged or other transactions involving the
Company that may adversely affect Holders.
 
    The Company's ability to repurchase Notes upon the occurrence of a Change in
Control is subject to limitations. There can be no assurance that the Company
would have the financial resources, or would be able to arrange financing, to
pay the Repurchase Price for all the Notes that might be delivered by Holders of
Notes seeking to exercise the repurchase right. Moreover, although under the
Indenture the Company may elect, subject to satisfaction of certain conditions,
to pay the repurchase price for the Notes using shares of Class A Common Stock,
the terms of the 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 equity of the Company that is not mandatorily
redeemable and up to $3 million in cash redemptions) and the Company's ability
to repurchase Notes may be limited or prohibited by the terms of borrowing
arrangements, including Senior Indebtedness, existing at the time of a Change in
Control. The Company's ability to repurchase Notes with cash may also be limited
by the terms of its subsidiaries' borrowing arrangements due to dividend
restrictions. Any failure by the Company to repurchase the Notes when required
following a Change in Control would result in an Event of Default under the
Indenture whether or not such repurchase is permitted by the subordination
provisions of the Indenture. Any such default may, in turn, cause a default
under Senior Indebtedness of the Company. Moreover, the occurrence of a Change
in Control could result in an event of default under the Company's Credit
Facility and may cause an event of default under terms of other Senior
Indebtedness of the Company. As a result, in each case, any repurchase of the
Notes would, absent a waiver, be prohibited under the subordination provisions
of the Indenture until the Senior Indebtedness is paid in full. In addition, the
Company's repurchase of Notes as a result of the occurrence of a Change in
Control may be prohibited or limited by, or create an event of default under,
the terms of agreements related to borrowings which the Company may enter into
from time to time, including agreements relating to Senior Indebtedness. See "--
Subordination".
 
MERGERS AND SALES OF ASSETS BY THE COMPANY
 
    The Company may not consolidate with or merge into any other Person or
convey, transfer, sell or lease its properties and assets substantially as an
entirety to any Person, and the Company shall not permit any Person to
consolidate with or merge into the Company or convey, transfer, sell or lease
such Person's properties and assets substantially as an entirety to the Company
unless (a) the Person formed by such consolidation or into or with which the
Company is merged or the Person to which the properties and assets of the
Company are so conveyed, transferred, sold or leased shall be a corporation,
limited liability company, partnership or trust organized and existing under the
laws of the United States, any State thereof or the District of Columbia and, if
other than the Company, shall expressly assume the payment of the principal of,
premium, if any, and interest on the Notes and the performance of the other
covenants of the Company under the Indenture, and (b) immediately after giving
effect to such transaction, no Event of Default, and no event that, after notice
or lapse of time or both, would become an Event of Default, shall have occurred
and be continuing.
 
                                       23
<PAGE>
EVENTS OF DEFAULT
 
    The following will be Events of Default under the Indenture: (a) failure to
pay principal of or premium, if any, on any Note when due, whether or not such
payment is prohibited by the subordination provisions of the Notes and the
Indenture; (b) failure to pay any interest (including any Liquidated Damages) on
any Note when due, continuing for 30 days, whether or not such payment is
prohibited by the subordination provisions of the Notes and the Indenture; (c)
failure to provide a Company Notice in the event of a Change in Control whether
or not such notice is prohibited by the subordination provisions of the Notes
and the Indenture; (d) failure to perform any other covenant of the Company in
the Indenture, continuing for 60 days (plus an additional 60 days in the case of
defaults subject to cure, provided the Company commences such cure within the
initial 60 days and is diligently pursuing such cure) after written notice as
provided in the Indenture; (e) any indebtedness under any bonds, debentures,
notes or other evidences of indebtedness for money borrowed by the Company in an
aggregate principal amount in excess of $25,000,000 is not paid at final
maturity thereof (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 (f) certain events of bankruptcy, insolvency or reorganization.
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 of the Holders, unless such Holders shall
have offered to the Trustee reasonable indemnity. Subject to such provisions for
the 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 as specified in clause (f) above) shall
occur and be 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; provided,
however, that 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 such
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
as specified in clause (f) above occurs and is continuing, then the principal
of, and accrued interest on, all the Notes shall 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".
 
    No Holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such Holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and the Holders of at least 25% in aggregate principal amount of the
outstanding Notes shall have made written request, and offered reasonable
indemnity, to the Trustee to institute such Proceeding as trustee, and the
Trustee shall not have received from the Holders of a majority in aggregate
principal amount of the outstanding Notes a director inconsistent with such
request and shall have failed to institute such proceeding within 60 days.
However, such limitations do not apply to a suit instituted by a Holder of a
Note for the enforcement of payment of the principal of, premium, if any, or
interest (including Liquidated Damages) on such Note on or after the respective
due dates expressed in such Note or of the right to convert such Note in
accordance with the Indenture.
 
    The Company will be required to furnish to the Trustee annually a statement
as to the performance by the Company of certain of its obligations under the
Indenture and as to any default in such performance.
 
                                       24
<PAGE>
MEETINGS, MODIFICATION AND WAIVER
 
    The Indenture contains provision 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 the Company 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. However, no such modification or amendment may, without the consent of
the Holder of each outstanding Note affected thereby (a) change the stated
maturity of the principal of, or any installment of interest on, any Note, (b)
reduce the principal amount of, or the premium, if any, or interest on, any
Note, (c) reduce the amount payable upon a redemption or mandatory repurchase,
(d) modify the provisions with respect to the repurchase right of the Holders in
a manner adverse to the Holders, (e) change the place or currency of payment of
principal of, premium, if any, or interest on, any Note (including any payment
of Liquidated Damages or of the Repurchase Price in respect of such Note), (f)
impair the right to institute suit for the enforcement of any payment on or with
respect to any Note, (g) modify the obligation of the Company to maintain an
office or agency in New York City, (h) except as otherwise permitted or
contemplated by provisions concerning consolidation, merger, conveyance,
transfer, sale or lease of all or substantially all of the property and assets
of the Company, adversely affect the right of Holders to convert any of the
Notes or to require the Company to repurchase any Note other than as provided in
the Indenture, (i) modify the subordination provisions in a manner adverse to
the Holders of the Notes, (j) reduce the above-stated percentage of outstanding
Notes necessary to modify or amend the Indenture, (k) reduce the percentage of
aggregate principal amount of outstanding Notes necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults, (l) reduce the percentage in aggregate principal amount of outstanding
Notes required for the adoption of a resolution or the quorum required at any
meeting of Holders of Notes at which a resolution is adopted, or (m) modify the
obligation of the Company to deliver information required under Rule 144A to
permit resales of Notes and Class A Common Stock issuable upon conversion
thereof in the event the Company ceases to be subject to certain reporting
requirements under the United States securities laws. The quorum at any meeting
called to adopt a resolution will be persons holding or representing a majority
in aggregate 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.
 
    The Holders of a majority in aggregate principal amount of the outstanding
Notes may waive compliance by the Company with certain restrictive provisions of
the Indenture by written consent or by the adoption of a resolution at a
meeting. The Holders of a majority in aggregate principal amount of the
outstanding Notes also may waive any past default under the Indenture, except a
default in the payment of principal, premium, if any, or interest, by written
consent.
 
REGISTRATION RIGHTS
 
    The Company entered into a registration rights agreement with the initial
purchasers of the Notes (the "Registration Rights Agreement") pursuant to which
the Company, at the Company's expense and for the benefit of the holders of the
Registered Notes and the shares of Common Stock issuable upon conversion thereof
(together, the "Registrable Securities"), (i) filed with the Commission, within
90 days after the date of last original issuance of the Notes, a registration
statement to which this Prospectus relates (the "Shelf Registration Statement")
covering resales of the Registrable Securities, (ii) has used reasonable efforts
to cause the Shelf Registration Statement to be declared effective under the
Securities Act within 180 days after the date of last original issuance of the
Notes and (iii) will use reasonable efforts to keep effective the Shelf
Registration Statement until two years after the date it is declared effective
or, if
 
                                       25
<PAGE>
earlier, until there are no outstanding Registerable Securities (the
"Effectiveness Period"). The Company will be permitted to suspend the use of the
prospectus which is part of the Shelf Registration Statement in connection with
sales of Registrable Securities during certain periods of time under certain
circumstances relating to pending corporate developments, public filing with the
Commission and other events. The Company will provide to each holder of
Registrable Securities copies of the prospectus that is a part of the Shelf
Registration Statement, notify each holder when the Shelf Registration Statement
has become effective and take certain other actions as are required to permit
public resales of the Registrable Securities.
 
    In the event that the Shelf Registration Statement ceases to be effective
(or the holders of Registrable Securities are otherwise prevented or restricted
by the Company from effecting sales pursuant thereto) (an "Effective Failure")
during the Effectiveness Period for more than 60 days, whether or not
consecutive, during any 12-month period then the interest rate borne by
Registered Notes will increase by an additional one-half of one percent (.5%)
per annum from the 61st day of the applicable 12-month period until such time as
the Effective Failure is cured.
 
    Prior to the filing of the Shelf Registration Statement, the Company gave
notice of its intention to make such filing to each of the holders of the
Registrable Securities in the same manner as the Company would give notice to
holders of Securities under the Indenture. Such notice sought, among other
things, a determination from each of such holders as to whether such holder
elects to sell Registrable Securities pursuant to the Registration Statement.
 
    A holder who so elected to sell any Registrable Securities pursuant to the
Shelf Registration Statement is 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 connection with such sales and will be bound by the provisions
of the Registration Rights Agreement which are applicable to a holder making
such election (including certain indemnification provisions).
 
    Any holder of any Registrable Securities wishing to include such holder's
Registrable Securities in the Shelf Registration Statement must deliver a
Selling Securityholder's Questionnaire substantially in the form attached as
Annex A to this Offering Circular to the Company within 30 days after notice
from the Company of its intention to file the Shelf Registration Statement (the
"Questionnaire Deadline") (each such holder, an "Electing Holder"). The Company
will include in the Shelf Registration Statement the Registrable Securities of
Electing Holders. If the Shelf Registration Statement shall have been filed
prior to the Questionnaire Deadline, the Company will file, as promptly as
reasonably practicable and in any event no later than 10 days after the
Questionnaire Deadline, a supplement (if the Shelf Registration Statement shall
then be effective) or an amendment (if the Shelf Registration Statement shall
not then be effective) with respect to the Registrable Securities of Electing
Holders (or shall otherwise ensure that such Registrable Securities are included
in the Shelf Registration Statement). A holder of Registrable Securities who
fails to deliver a properly completed and signed Selling Securityholder's
Questionnaire to the Company prior to the Questionnaire Deadline will not be
entitled to include its Registrable Securities in the Shelf Registration
Statement (or supplement or amendment thereto) first filed thereafter. After the
Questionnaire Deadline (or, if later, the date that the Shelf Registration
Statement becomes effective), the Company shall upon the request of any holder
of Registrable Securities that is not then an Electing Holder, as promptly as
reasonably practicable, send a Selling Securityholder's Questionnaire to such
holder. Following its receipt of a completed and signed questionnaire in return,
the Company will reasonably promptly include the Registrable Securities covered
thereby in the Shelf Registration Statement.
 
    The Company agreed in the Registration Rights Agreement to use its
reasonable efforts to cause such shares of Class A Common Stock issuable upon
conversion of the Notes to be listed on the New York Stock Exchange, or, if the
Class A Common Stock is not then listed on the New York Stock Exchange, to
 
                                       26

be listed on such exchange as the Class A Common Stock is then listed, upon
effectiveness of the Shelf Registration Statement.
 
    This summary of certain provisions of the Registration Rights Agreement does
not purpose to be complete and is subject to, and qualified in its entirety by
reference to, all the provisions of the Registration Rights Agreement, a copy of
which will be made available to beneficial owners of the Notes upon request to
the Company.
 
TITLE
 
    The Company, the Trustee, any Paying Agent and any Conversion Agent may
treat the registered owner (as reflected in the security register) of any Note
as the absolute owner thereof (whether or not such Note shall be overdue) for
the purpose of making payment and for all other purposes.
 
NOTICES
 
    Notice to Holders of the Notes will be given by mail to the addresses of
such Holders 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 at least once not less than 30
nor more than 60 days prior to the redemption date (which notice shall be
irrevocable) and will specify the Redemption Date.
 
REPLACEMENT OF NOTES
 
    Notes that become mutilated, destroyed, stolen or lost will be replaced by
the Company at the expense of the Holder upon delivery to the Trustee of the
mutilated Notes or evidence of the loss, theft or destruction thereof
satisfactory to the Company and the Trustee. In the case of a lost, stolen or
destroyed Note, indemnity satisfactory to the Trustee and the Company may be
required at the expense of the Holder of such Note before a replacement Note
will be issued.
 
PAYMENT OF STAMP AND OTHER TAXES
 
    The Company will pay all stamp and other duties, if any, which may be
imposed by the United States or the United Kingdom or any political subdivision
thereof or taxing authority thereof or therein with respect to the issuance of
the Notes. The Company 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 will be governed by and construed in accordance
with the laws of the State of New York, United States of America.
 
THE TRUSTEE
 
    In case an Event of Default shall occur (and shall not be cured), 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.

                              PLAN OF DISTRIBUTION
 
    The Notes were issued to the Selling Securityholders in connection with an
underwritten private placement. The Notes and Class A Common Stock issuable upon
the conversion thereof may be sold from time to time directly by the undersigned
Selling Securityholder or, alternatively, through underwriters, broker-dealers
or agents. Such Notes and Class A Common Stock 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. Such
sales may be effected in transactions (which may involve crosses or block
transactions) (i) on any national securities exchanges or U.S. inter-dealer
quotation system of a registered national securities association on which the
Notes or Class A Common Stock may be listed or quoted at the time of sale, (ii)
in the over-the-counter market, (iii) in transactions otherwise than on such
exchanges or services or in the over-the-counter market, or (iv) through the
writing of options. In connection with sales of the Notes or Class A Common
Stock or otherwise, the Selling Securityholder may enter into hedging
transactions with broker-dealers, which may in turn engage in short sales of the
Notes or Class A Common Stock in the course of hedging the positions they
assume. The Selling Securityholder may also sell Notes or Class A Common Stock
short and deliver Registrable Securities to close out such short positions, or
loan or pledge Notes or Class A Common Stock to broker-dealers that in turn may
sell such securities.
 
    Pursuant to the provisions of the Registration Rights Agreement entered into
by and between the Company and Goldman, Sachs & Co., the Company will pay the
costs and expenses incident to its registration and qualification of the Notes
offered hereby, including registration and filing fees. In addition, the Company
has agreed to indemnify the Selling Securityholders against certain liabilities,
including liabilities arising under the Securities Act.
 
    The Selling Securityholders and any broker-dealer participating in the
distributing of the Notes may be deemed to be "underwriters" within the meaning
of the Securities Act, and any profit and any commissions paid or any discounts
or concessions allowed to any such broker-dealer may be deemed to be
underwriting discounts and commissions under the Securities Act. The Selling
Securityholders may indemnify any broker-dealer that participates in
transactions involving the sale of Notes against certain liabilities, including
liabilities under the Securities Act.
 
    There can be no assurances that the Selling Securityholders will sell any or
all of the Notes offered by them hereunder.
 
                                 LEGAL MATTERS
 
    The validity of the securities offered hereby will be passed upon by Hughes
