 (1) The proposed maximum offering price per unit will be determined from time
     to time by the registrants in connection with the issuance by the
     registrants of the securities registered hereunder. In no event will the
     aggregate initial public offering price of all securities issued from time
     to time pursuant to this registration statement exceed $1,500,000,000. The
     aggregate amount of Class A Common Stock registered hereunder is further
     limited to that which is permissible under Rule 415(a)(4) of the Securities
     Act. The securities registered hereunder may be sold separately or as units
     with other securities registered hereunder.

 (2) The proposed maximum aggregate offering price has been estimated solely for
     the purpose of calculating the registration fee in accordance with Rule
     457(o) of the Securities Act.

 (3) Subject to note (1) above, there is being registered hereunder an
     indeterminate principal amount of senior and subordinated debt securities
     as may be sold, from time to time, by the registrant at indeterminate
     prices, including an indeterminate amount of debt securities as may be
     issued in connection with the issuance of preferred securities of ACS Trust
     I and ACS Trust II or in connection with warrants registered hereby. If any
     debt securities are issued at an original issue discount, then the offering
     price shall be in the greater principal amount as shall result in an
     aggregate initial offering price not to exceed $1,500,000,000 less the
     dollar amount of any securities previously issued hereunder.

 (4) Subject to note (1) above, there is being registered hereunder an
     indeterminate number of shares of Class A Common Stock or, in the case of
     the selling stockholder, an indeterminate number of shares of Class A
     Common Stock up to 1,504,562, as may be sold, from time to time, by the
     registrant or the selling stockholder at indeterminate prices. There are
     also being registered hereunder an indeterminate number of shares of Class
     A Common Stock as may be issuable upon conversion of preferred stock or
     debt securities or exercise of warrants registered hereby. No separate
     consideration will be received for Class A Common Stock issued upon
     conversion of preferred stock or debt securities. The above also includes
     an equivalent number of rights to purchase shares of Class A Common Stock
     issuable under the registrant's First Amended and Restated Rights
     Agreement.

 (5) Subject to note (1) above, there is being registered hereunder an
     indeterminate number of shares of preferred stock as may be sold, from time
     to time, by the registrant at indeterminate prices. There are also being
     registered hereunder an indeterminate number of shares of preferred stock
     as may be issuable by the registrant in connection with the issuance of
     depositary shares or warrants registered hereby.

 (6) Subject to note (1) above, there is being registered hereunder an
     indeterminate number of depositary shares to be evidenced by depositary
     receipts issued pursuant to a depositary agreement. In the event the
     registrant elects to offer to the public fractional shares of the preferred
     stock registered hereunder, depositary receipts will be distributed to
     those persons purchasing such fractional interests, and such shares will be
     issued to the depositary bank under the depositary agreement.

 (7) Subject to note (1) above, there is being registered hereunder an
     indeterminate number of warrants to purchase Class A Common Stock,
     preferred stock or debt securities of the registrant, as may be sold, from
     time to time, by the registrant at indeterminate prices.

 (8) Subject to note (1) above, there is being registered hereunder an
     indeterminate number of shares of preferred securities of ACS Trust I and
     ACS Trust II, as may be sold, from time to time, by the trusts at
     indeterminate prices.

 (9) No additional consideration will be received from the Affiliated Computer
     Services, Inc. guarantees with respect to the trust preferred securities.

(10) Not applicable pursuant to General Instruction II.D. of Form S-3.

(11) The registrants previously filed with the Securities and Exchange
     Commission on November 15, 1999, a shelf registration statement
     (Registration Number 333-90943) for the registration of $500,000,000 of
     securities. No securities were sold pursuant to such registration statement
     and such registration statement has been terminated. The filing fee paid by
     the registrants in connection with such prior registration statement is
     offset, pursuant to Rule 457(p) of the Securities Act, against the filing
     fee due in connection with this registration statement, resulting in a new
     net paid filing fee of $250,000.

     Generally, whenever we use the terms "we," "our," "us," and "ACS," we are
referring to Affiliated Computer Services, Inc. and its subsidiaries. However,
for purposes of the "Description of Notes," the "Description of Capital Stock,"
the "Description of Warrants" and the "Description of Depositary Shares"
sections of this prospectus, and when the context otherwise requires, the terms
"we," "our," "us," and "ACS" refer only to Affiliated Computer Services, Inc.

     This prospectus is part of a registration statement we filed with the
Securities and Exchange Commission using a "shelf" registration process. The
registration statement also includes a prospectus under which ACS Trust I and
ACS Trust II, two of our subsidiaries, may offer from time to time trust
preferred securities guaranteed by us and we may offer our related subordinated
debt securities. Under the shelf registration process, we may offer from time to
time any combination of the securities described in these two prospectuses in
one or more offerings with a total initial offering price of up to
$1,500,000,000. This prospectus provides you with a general description of the
senior debt securities, subordinated debt securities, Class A Common Stock,
preferred stock, depositary shares and warrants we may offer. Each time we use
this prospectus to offer these securities, we will provide a prospectus
supplement that will contain specific information about the terms of that
offering such as:

     - the type and amount of securities which we propose to sell;

     - the initial offering price of such securities;

     - the names and compensation of the underwriters or agents, if any, through
       or to which we will sell the securities;

     - information about any securities exchanges or automated quotation systems
       on which the securities will be listed or traded;

     - any material United States federal income tax considerations applicable
       to the securities; and

     - any other material information about the offering and the sale of the
       securities.

The prospectus supplement may also add, update, or change information contained
or incorporated by reference in this prospectus. Please carefully read this
prospectus and the prospectus supplement, together with the additional
information described under the heading "Where You Can Find More Information."

     We were formed in 1988 to participate in the trend to outsource information
processing requirements to third parties. This outsourcing enables businesses to
focus on core operations, respond to rapidly changing technologies and reduce
expenses associated with business processes and data processing. Our business
strategy is to expand our client base and enhance our service offerings through
both internal marketing and the acquisition of complementary companies. Our
marketing efforts focus on developing long-term relationships with clients that
choose to outsource mission critical business processes and information
technology requirements. Our focus over the last several years has been to
participate in the expanding business process outsourcing market. Our business
expansion has been accomplished both from internal growth as well as through
acquisitions.

     We serve two primary markets. Our largest market is the commercial sector.
Within the commercial sector, which includes state and local governments, we
provide business process outsourcing, systems integration services and
technology outsourcing to a variety of clients nationwide, including healthcare
providers, retailers, local municipalities, state agencies, wholesale
distributors, manufacturers, utilities, financial institutions and insurance
companies.

     We also serve the federal government market. Our services in this market
are comprised of business process outsourcing, systems integration services and
technology outsourcing. Within our federal government business, approximately
half of our revenues are derived from civilian agencies, including the
Department of Education, with the remaining half from Department of Defense
agencies.

     Additional information concerning our business and operations is
incorporated by reference herein from our other SEC filings and may be included
in applicable prospectus supplements.

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

                                USE OF PROCEEDS

     Except as otherwise provided in the applicable supplement to this
prospectus, we expect to use the net proceeds from the sale of the securities we
are offering in this prospectus for general corporate purposes. These purposes
may include:

     - repayment of indebtedness, including indebtedness incurred in connection
       with acquisitions;

     - redemption or repurchase of our securities;
                                        2
   9

     - additions to working capital;

     - capital expenditures; or

     - acquisitions.

     We will set forth specific information about the use of proceeds from the
sale of the securities in the applicable prospectus supplement. Before any net
proceeds are applied to the uses described above, the proceeds may be invested
in short-term or marketable securities.

     If our chairman, Darwin Deason, sells any of his Class A Common Stock
through this prospectus, we will not receive any proceeds from his sale of
shares of Class A Common Stock. See "Selling Securityholder."

                  RATIO OF EARNINGS TO COMBINED FIXED CHARGES
                            AND PREFERRED DIVIDENDS

     The following table sets forth our ratio of earnings to fixed charges for
the periods indicated:



   FISCAL YEAR ENDED JUNE 30,
--------------------------------
1997   1998   1999   2000   2001
----   ----   ----   ----   ----
                
3.9    3.7    4.2    4.6    5.4


     For the purpose of calculating the ratio of earnings to fixed charges,
earnings are defined as earnings before income taxes and extraordinary items
plus fixed charges. Fixed charges consist of interest expense, amortization of
debt issue costs and a portion of rental expense representative of interest.
Since there have been no preferred securities outstanding during the periods
presented, the ratio of earnings to combined fixed charges and preferred
dividends does not differ from the presentation of the ratio of earnings to
fixed charges presented above.

                         DESCRIPTION OF DEBT SECURITIES

     The debt securities covered by this prospectus will be our general
unsecured obligations. The debt securities will be either senior debt securities
or subordinated debt securities. We will issue the debt securities under one or
more separate indentures between us and a trustee named in the indentures.
Senior debt securities will be issued under a senior indenture, and subordinated
debt securities will be issued under a subordinated indenture. We sometimes call
the senior indenture and the subordinated indenture the "indentures."

     We have summarized selected provisions of the indentures and the debt
securities below. You should read the indentures for more details regarding the
provisions we describe below and for other provisions that may be important to
you. We have filed the forms of the indentures with the SEC as exhibits to the
registration statement of which this prospectus forms a part. Please read "Where
You Can Find More Information."

GENERAL

     The senior debt securities will constitute senior debt and will rank
equally with all our unsecured and unsubordinated debt. The subordinated debt
securities will be subordinated to, and thus have a junior position to, any
senior debt securities and all our other senior debt. In some cases, and as
would be described in a prospectus supplement, a series of our subordinated debt
may also be junior in some respects to a different series of subordinated debt.
The indentures will not limit the amount of debt we may issue under the
indentures, and, unless we inform you otherwise in the prospectus supplement,
they will not limit the amount of other debt or securities we may incur or
issue. We may issue debt securities under either indenture from time to time in
one or more series, each in an amount we authorize prior to issuance.

                                        3
   10

     We conduct a substantial part of our operations through our subsidiaries,
and our subsidiaries generate a significant part of our operating income and
cash flow. As a result, distributions or advances from our subsidiaries are
important sources of funds to meet our debt service obligations. Contractual
provisions or laws, as well as our subsidiaries' financial condition and
operating requirements, may limit our ability to obtain from our subsidiaries
cash that we need to pay our debt service obligations, including payments on the
debt securities. In addition, holders of the debt securities will have a junior
position to the claims of creditors of our subsidiaries on their assets and
earnings.

     Unless we inform you otherwise in the prospectus supplement, the indentures
and the debt securities will not contain:

     - any covenants or other provisions designed to protect holders of the debt
       securities in the event we participate in a highly leveraged transaction;
       or

     - provisions that give holders of the debt securities the right to require
       us to repurchase their securities in the event of a decline in our credit
       rating resulting from a takeover, recapitalization or similar
       restructuring or otherwise.

     The prospectus supplement relating to any series of debt securities being
offered will include specific terms relating to the offering. These terms will
include some or all of the following:

     - the title of the debt securities;

     - the total principal amount of the debt securities;

     - whether the debt securities are senior debt securities or subordinated
       debt securities;

     - whether a series of subordinated debt is junior in any respect to another
       series of subordinated debt;

     - whether we will issue the debt securities in individual certificates to
       each holder or in the form of temporary or permanent global securities
       held by a depository on behalf of holders;

     - the date or dates on which the principal of and any premium on the debt
       securities will be payable;

     - any interest rate, the date from which interest will accrue, interest
       payment dates and record dates for interest payments;

     - whether and under what circumstances any additional amounts with respect
       to the debt securities will be payable;

     - the place or places where payments on the debt securities will be
       payable;

     - any provisions for redemption or early repayment;

     - any sinking fund or other provisions that would obligate us to redeem,
       purchase or repay the debt securities prior to maturity;

     - the denominations in which we may issue the debt securities;

     - whether payments on the debt securities will be payable in foreign
       currency or currency units or another form, and whether payments will be
       payable by reference to any index or formula;

     - the portion of the principal amount of the debt securities that will be
       payable if the maturity is accelerated, if other than the entire
       principal amount;

     - any additional means of defeasance of the debt securities, any additional
       conditions or limitations to defeasance of the debt securities or any
       changes to those conditions or limitations;

     - any changes or additions to the events of default or covenants this
       prospectus describes;

     - any restrictions or other provisions relating to the transfer or exchange
       of the debt securities;

     - any terms for the conversion or exchange of the debt securities for other
       securities issued by ACS or any other entity; and

     - any other terms of the debt securities.

                                        4
   11

     We may sell the debt securities at a discount, which may be substantial,
below their stated principal amount. Those debt securities may bear no interest
or interest at a rate that at the time of issuance is below market rates.

     If we sell any of the debt securities for any foreign currency or currency
unit or if payments on the debt securities are payable in any foreign currency
or currency unit, we will describe in the prospectus supplement the
restrictions, elections, material tax consequences, specific terms and other
information relating to those debt securities and the foreign currency or
currency unit.

OUR SENIOR DEBT SECURITIES

     Generally speaking, our senior debt securities will rank equally with all
of our other senior debt, except to the extent any such debt is secured by our
assets.

     "Senior debt" is defined to include all debt, not expressed to be
subordinate or junior in right of payment to any other indebtedness of ACS.

     Unless we inform you otherwise in the prospectus supplement, the term
"debt" means:

     - indebtedness for borrowed money;

     - obligations evidenced by bonds, debentures, notes or similar instruments;

     - obligations, including reimbursement obligations, relating to letters of
       credit or similar instruments;

     - obligations to pay the deferred and unpaid purchase price of property or
       services, except trade payables and accrued expenses incurred in the
       ordinary course of business;

     - capitalized lease obligations;

     - debt of a third party secured by a lien on any asset of ACS;

     - debt of others guaranteed by ACS to the extent of the guarantee; and

     - obligations for claims under derivative products.

     Any senior debt securities offered pursuant to the senior indenture will be
senior in right of payment to our subordinated debt securities.

OUR SUBORDINATED DEBT SECURITIES

     Our subordinated debt securities will have a junior position to all of our
senior debt. Under the subordinated indenture, payment of the principal,
interest and any premium on the subordinated debt securities will generally be
subordinated and junior in right of payment to the prior payment in full of all
senior debt. Further, a series of subordinated debt may be junior in some
respects to another series of subordinated debt. The subordinated indenture will
provide that no payment of principal, interest and any premium on the
subordinated debt securities may be made in the event:

     - we fail to pay the principal, interest, premium or any other amounts on
       any senior debt when due; or

     - we default in performing any other covenant (a "covenant default") in any
       senior debt if the covenant default allows the holders of that senior
       debt to accelerate the maturity of the senior debt they hold.

The subordinated indenture will not limit the amount of senior debt that we may
incur.

     Unless we inform you otherwise in the prospectus supplement, a covenant
default will prevent us from making payments on the subordinated debt securities
only for up to 179 days after holders of the senior debt give the trustee for
the subordinated debt securities notice of a covenant default.

                                        5
   12

     Unless provided in a prospectus supplement, any subordinated debt
securities offered pursuant to the subordinated indenture will rank equally in
right of payment with each other and to our $230,000,000 original principal
amount of 4% convertible subordinated notes due March 15, 2005 and our
$316,990,000 original principal amount of 3.50% convertible subordinated notes
due February 15, 2006.

     The subordinated indenture will prohibit us from making for a specified
time period any payment of principal of or premium, if any, or interest on, or
sinking fund requirements for, the subordinated debt securities during the
continuance of any default in respect of senior debt, unless and until the
default on the senior debt is cured or waived.

     Upon any distribution of our assets in connection with any dissolution,
winding up, liquidation, reorganization, bankruptcy or other similar proceeding
relative to us, our creditors or our property, the holders of our senior debt
will first be entitled to receive payment in full of the principal thereof and
premium, if any, and interest due on the senior debt securities before the
holders of the subordinated debt securities are entitled to receive any payment
of the principal of and premium, if any, or interest on the subordinated debt
securities. Because of this subordination, if we become insolvent, our creditors
who are not holders of our senior debt or of our subordinated debt securities
may recover less, ratably, than holders of our senior debt securities but may
recover more, ratably, than holders of our subordinated debt securities.

     The subordination does not affect our obligation, which is absolute and
unconditional, to pay, when due, principal of, premium, if any, and interest on
the subordinated debt securities. In addition, the subordination does not
prevent the occurrence of any default under the indenture.

GLOBAL CERTIFICATES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that will be deposited with a depository
identified in a prospectus supplement. The specific terms of the depository
arrangements with respect to any debt securities of a series will be described
in a prospectus supplement.

     Unless otherwise specified in a prospectus supplement, debt securities
issued in the form of a global certificate to be deposited with a depository
will be represented by a global certificate registered in the name of the
depository or its nominee. Upon the issuance of a global certificate in
registered form, the depository for the global certificate will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the debt securities represented by the global certificate to the accounts of
institutions that have accounts with the depository or its nominee. The
depository or its nominee are referred to in this prospectus as participants.
The accounts to be credited shall be designated by the underwriters or agents of
the debt securities, or by us if the debt securities are offered and sold
directly by us.

     Ownership of beneficial interests in a global certificate will be limited
to participants or persons that may hold interests through participants.
Ownership of beneficial interests by participants in a global certificate will
be shown on, and the transfer of that ownership interest will be effected only
through, records maintained by the depository or its nominee for the global
certificate. Ownership of beneficial interests in a global certificate by
persons that hold through participants will be shown on, and the transfer of
that ownership interest within a participant will be effected only through,
records maintained by that participant. The laws of some jurisdictions require
that some purchasers of securities take physical delivery of their securities in
definitive form. These limits and laws may impair your ability to transfer
beneficial interests in a global certificate.

     So long as the depository for a global certificate in registered form, or
its nominee, is the registered owner of the global certificate, the depository
or its nominee, as the case may be, will be considered the sole owner or holder
of the debt securities of the series represented by the global certificate for
all purposes under the indentures. Except as set forth below, owners of
beneficial interests in a global certificate will not be entitled to have debt
securities of the series represented by the global certificate

                                        6
   13

registered in their names, will not receive or be entitled to receive physical
delivery of debt securities in definitive form, and will not be considered the
owners or holders of the global certificate under the applicable indenture.

     Payment of principal of, premium, if any, and any interest on debt
securities of a series registered in the name of or held by a depository or its
nominee will be made to the depository or its nominee, as the case may be, as
the registered owner or the holder of a global certificate representing the debt
securities. None of us, the trustee, any paying agent, or the applicable debt
security registrar for the debt securities will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a global certificate for debt securities or
for maintaining, supervising or reviewing any records relating to beneficial
ownership interests.

     We expect that the depository for debt securities of a series, upon receipt
of any payment of principal, premium or interest in respect of a permanent
global certificate, will credit immediately participants' accounts with payments
in amounts proportionate to their respective beneficial interests in the
principal amount of the global certificate as shown on the records of the
depository. We also expect that payments by participants to owners of beneficial
interests in a global certificate held through those participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in street name, and those payments will be the responsibility of the
participants. However, we have no control over the practices of the depository
and/or the participants and there can be no assurance that these practices will
not be changed.

     Unless it is exchanged in whole or in part for debt securities in
definitive form, a global certificate may generally be transferred only as a
whole unless it is being transferred to particular nominees of the depository.

     Unless otherwise stated in any prospectus supplement, The Depository Trust
Company, New York, New York will act as depository. Beneficial interests in
global certificates will be shown on, and transfers of global certificates will
be effected only through, records maintained by The Depository Trust Company and
its participants.

EVENTS OF DEFAULT

     Under the indentures an event of default, unless a prospectus supplement
provides otherwise, will mean any of the following:

     - our failure to pay principal of or any premium on any debt securities of
       that series when due, regardless of whether such payment became due
       because of maturity, redemption, acceleration or otherwise, or is
       required by any sinking fund established with respect to such series;

     - our failure to pay interest or any required additional amounts on any
       debt securities of that series for 30 days;

     - our failure to comply with any of our covenants or agreements in the debt
       securities of that series or the applicable indenture, other than an
       agreement or covenant that we have included in that indenture solely for
       the benefit of other series of debt securities, for the period of days
       specified in the applicable prospectus supplement after written notice by
       the trustee or by the holders of at least 25% in principal amount of all
       the outstanding debt securities issued under that indenture that are
       affected by that failure;

     - certain defaults with respect to our debt (other than the debt securities
       of that series) in an aggregate principal amount in excess of that dollar
       amount specified in the related prospectus supplement and supplemental
       indenture for the debt securities, which consists of the failure to make
       any payment at maturity or that results in acceleration of the maturity
       of such debt;

     - specified events involving our bankruptcy, insolvency or reorganization;
       or

     - any other event of default provided for that series of debt securities.

                                        7
   14

     An event of default for a particular series of debt securities does not
necessarily constitute an event of default for any other series of debt
securities issued under an indenture. The trustee may withhold notice to the
holders of debt securities of any default (except in the payment of principal or
interest) if it considers on good faith that the withholding of notice is in the
best interests of the holders.

     If an event of default for any series of debt securities occurs and is
continuing, the trustee or the holders of at least 25% in principal amount of
the outstanding debt securities of the series affected by the default, or, in
some cases, 25% in principal amount of all senior debt securities or
subordinated debt securities affected, voting as one class, may declare the
principal of and all accrued and all unpaid interest on those debt securities to
be due and payable. If an event of default relating to events of bankruptcy,
insolvency or reorganization occurs, the principal of and all accrued and unpaid
interest on all the debt securities will become immediately due and payable
without any action on the part of the applicable trustee or any holder. The
holders of a majority in principal amount of the outstanding debt securities of
the series affected by the default, or of all senior debt securities or
subordinated debt securities affected, voting as one class, may in some cases
rescind this accelerated payment requirement. Depending on the terms of our
other indebtedness, an event of default under either of the indentures may give
rise to cross defaults on our other indebtedness.

     The indentures will limit the right to institute legal proceedings. No
holder of any debt securities will have the right to bring a claim under an
indenture unless:

     - the holder has given written notice of a continuing default for that
       series to the trustee;

     - the holders of not less than 25% of the aggregate principal amount of
       debt securities of the series shall have made a written request to the
       trustee to bring the claim and furnished the trustee reasonable
       indemnification as the trustee may require;

     - the trustee has not commenced an action within 60 days of receipt of the
       notice and indemnification; and

     - during the 60-day period following receipt of the notice and
       indemnification, no direction inconsistent with the request has been
       given to the trustee by the holders of not less than a majority of the
       aggregate principal amount of the debt securities of the series then
       outstanding.

Subject to applicable law and any applicable subordination provisions, the
holders of debt securities may enforce payment of the principal of or premium,
if any, or interest on their debt securities.

     Except as provided in the next sentence, the holders of a majority in
aggregate principal amount of any series of debt securities may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee or exercising any power conferred on the trustee. The trustee may
decline to follow the holders' direction if, being advised by counsel, the
trustee determines that the action is not lawful, or if the trustee in good
faith determines that the action would unduly prejudice the holders of the debt
securities not taking part in the action or would impose personal liability on
the trustee.

     Each indenture will provide that, in case an event of default in respect of
a particular series of debt securities has occurred, the trustee must use the
degree of care of a prudent man in the conduct of his own affairs. Subject to
these provisions, the trustee is under no obligation to exercise any of its
rights or power under the indenture at the request of any of the holders of the
debt securities of any series unless they have furnished to the trustee
reasonable security or indemnity.

     We will be required to furnish to the trustee an annual statement as to our
fulfillment of all of our obligations under the relevant indenture.

DEFEASANCE

     When we use the term "defeasance," we mean discharge from some or all of
our obligations under an indenture. If we deposit with the applicable trustee
funds or government securities sufficient to make

                                        8
   15

payments on the debt securities of a series on the dates those payments are due
and payable, then, at our option, either of the following will occur:

     - we will be discharged from our obligations with respect to the debt
       securities of that series ("legal defeasance"); or

     - we will no longer have any obligation to comply with the restrictive
       covenants under the applicable indenture, and the related events of
       default will no longer apply to us, but some of our other obligations
       under the indenture and the debt securities of that series, including our
       obligation to make payments on those debt securities, will survive
       ("covenant defeasance").

     If we effect a covenant defeasance of a series of debt securities, the
holders of the debt securities of the series affected will not be entitled to
the benefits of the applicable indenture, except for our obligations to:

     - register the transfer or exchange of debt securities;

     - replace stolen, lost or mutilated debt securities; and

     - maintain paying agencies and hold moneys for payment in trust.

     Unless we inform you otherwise in the prospectus supplement, we will be
required to deliver to the applicable trustee an opinion of counsel that the
deposit and related defeasance would not cause the holders of the debt
securities to recognize income, gain or loss for United States federal income
tax purposes. If we elect legal defeasance, that opinion of counsel must be
based on a ruling from the United States Internal Revenue Service or a change in
law to that effect.

CONSOLIDATION, MERGER OR SALE OF ASSETS

     Each indenture will generally permit us to consolidate or merge with
another entity. The indentures will also permit us to sell all or substantially
all of our property and assets. However, we will only consolidate or merge with
or into any other entity, or sell all or substantially all of our assets, in
accordance with the terms and conditions of the indentures. The indentures
provide that we may consolidate with another entity to form a new entity, or
merge into any other entity, or transfer or dispose of our assets substantially
as an entirety to any other entity only if:

     - the resulting or surviving entity assumes the due and punctual payments
       on the debt securities and the performance of our covenants and
       obligations under the applicable indenture and the debt securities; and

     - immediately after giving effect to the transaction, no default or event
       of default would occur and be continuing.

     The remaining or acquiring entity will be substituted for us in the
indentures with the same effect as if it had been an original party to the
indentures. Thereafter, the successor entity may exercise our rights and powers
under any indenture, in our name or in its own name. Any act or proceeding
required or permitted to be done by our board of directors or any of our
officers may be done by the board or officers of the successor entity.

MODIFICATION AND WAIVER

     We may amend or supplement either indenture if the holders of a majority in
principal amount of the outstanding debt securities of all series issued under
the applicable indenture and affected by the amendment or supplement, acting as
one class, consent to it. Without the consent of the holder of each debt
security affected, however, no amendment or supplement may:

     - reduce the amount of debt securities whose holders must consent to an
       amendment, supplement or waiver;

     - reduce the rate of or change the time for payment of interest on any debt
       security;
                                        9
   16

     - reduce the principal of, premium on or any mandatory sinking fund payment
       for any debt security;

     - change the stated maturity of any debt security;

     - reduce any premium payable on the redemption of any debt security or
       change the time at which any debt security may or must be redeemed;

     - change any obligation to pay additional amounts on any debt security;

     - make the payments on any debt security payable in any currency or
       currency unit other than as the debt security originally states;

     - impair the holder's right to institute suit for the enforcement of any
       payment on any debt security;

     - make any change in the percentage of principal amount of debt securities
       necessary to waive compliance with specified provisions of the applicable
       indenture or to make any change in the applicable indenture's provisions
       for modification;

     - waive a continuing default or event of default regarding any payment on
       any debt security; or

     - with respect to the subordinated indenture, modify the provisions
       relating to the subordination of any subordinated debt security in a
       manner adverse to the holder of that security.

     We and the applicable trustee may agree to amend or supplement either
indenture or waive any provision of either indenture without the consent of any
holders of debt securities in some circumstances, including:

     - to cure any ambiguity, omission, defect or inconsistency;

     - to provide for the assumption of our obligations under the indenture by a
       successor upon any merger, consolidation or asset transfer;

     - to provide for uncertificated debt securities in addition to or in place
       of certificated debt securities or to provide for bearer debt securities;

     - to provide any security for or add guarantees of any series of debt
       securities;

     - to comply with any requirement to effect or maintain the qualification of
       the indenture under the Trust Indenture Act of 1939;

     - to add covenants that would benefit the holders of any debt securities or
       to surrender any rights we have under the indenture;

     - to add events of default with respect to any debt securities;

     - to make any change that does not adversely affect any outstanding debt
       securities of any series in any material respect;

     - to facilitate the defeasance or discharge of any series of debt
       securities if that change does not adversely affect the holders of debt
       securities of that series or any other series under the indenture in any
       material respect; and

     - to provide for the acceptance of a successor or another trustee.

                                        10
   17

     The holders of a majority in principal amount of the outstanding debt
securities of any series, or of all senior debt securities or subordinated debt
securities affected, voting as one class, may waive any existing or past default
or event of default with respect to those debt securities. Those holders may
not, however, waive any default or event of default in any payment on any debt
security or compliance with a provision that cannot be amended or supplemented
without the consent of each holder affected.

CERTIFICATES AND OPINIONS TO BE FURNISHED TO THE TRUSTEE

     Each indenture will provide that, in addition to other certificates or
opinions that may be specifically required by other provisions of an indenture,
every time we ask the trustee to take action under the indenture, we must
provide a certificate of some of our officers and an opinion of counsel (who may
be our counsel) stating that, in the opinion of the signers, all conditions
precedent to the action have been complied with.

REPORT TO HOLDERS OF DEBT SECURITIES

     We will provide audited financial statements annually to the trustee. The
trustee will be required to submit an annual report to the holders of the debt
securities discussing, among other things, the trustee's eligibility to serve as
trustee, the priority of the trustee's claims regarding some advances made by
it, and any action taken by the trustee materially affecting the debt
securities.

THE TRUSTEE

     U.S. Trust Company of Texas, N.A. will initially serve as the trustee under
both our senior and subordinated indentures.

     Pursuant to applicable provisions of the indentures and the Trust Indenture
Act of 1939 governing trustee conflicts of interest, any uncured event of
default with respect to any series of debt securities will force the trustee to
resign as trustee under either the subordinated indentures or the senior
indentures. Any resignation requires the appointment of a successor trustee
under the applicable indenture in accordance with its terms and conditions.

     The trustee may resign or be removed by us under certain circumstances
specified in the indenture with respect to one or more series of debt securities
and a successor trustee may be appointed to act with respect to any series. The
holders of a majority in aggregate principal amount of the debt securities of
any series may remove the trustee with respect to the debt securities of that
series.

     Each indenture will contain limitations on the right of the trustee
thereunder, in the event that the trustee becomes our creditor, to obtain
payment of claims in particular cases or to realize on some property received in
respect of any claim as security or otherwise.

                          DESCRIPTION OF CAPITAL STOCK

     We may issue shares of our Class A Common Stock from time to time
hereunder.

     Our authorized capital stock consists of:

     - 500,000,000 shares of Class A Common Stock, $.01 par value,

     - 14,000,000 shares of Class B Common Stock, $.01 par value, and

     - 3,000,000 shares of preferred stock, $1.00 par value.

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

CLASS A COMMON STOCK AND CLASS B COMMON STOCK

  VOTING RIGHTS

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

  CONVERSION OF CLASS B COMMON STOCK

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

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

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

     No person or entity holding shares of Class B Common Stock may transfer the
shares, whether by sale, assignment, gift, bequest, appointment or otherwise,
except to certain permitted transferees.

  DIVIDENDS AND LIQUIDATION RIGHTS

     The holders of Class A Common Stock and Class B Common Stock are entitled
to receive dividends out of assets legally available therefore at times and in
amounts as the Board of Directors may from time to time determine. Subject to
any rights of preferred stock, upon liquidation and dissolution of ACS, the

                                        12
   19

holders of Class A Common Stock and Class B Common Stock are entitled to receive
all assets available for distribution to stockholders.

  OTHER RIGHTS

     The holders of Class A Common Stock and Class B Common Stock are not
entitled to preemptive or subscription rights. This means that holders of common
stock do not have rights to buy any portion of securities we may issue in the
future. There are no redemption or sinking fund provisions applicable to the
common stock.

RIGHTS AGREEMENT

     On August 5, 1997, we entered into a rights agreement and authorized and
declared a dividend distribution of one right for each share of Class A Common
Stock and one right for each share of Class B Common Stock, each as outstanding
at the close of business on August 25, 1997. Class A Common Stock and Class B
Common Stock issued after August 25, 1997 have been and will be issued with an
associated right. On April 2, 1999, we amended and restated the rights agreement
in order to comply with changes in Delaware law. We have summarized the material
provisions of our amended and restated stockholder rights plan below. The
summary is not complete. The terms of our stockholder rights plan are fully
described in our amended and restated rights agreement dated as of April 2,
1998, which is incorporated in this prospectus by reference. See "Where You Can
Find More Information."

     Under the amended and restated rights agreement, each share of Class A
Common Stock and Class B Common Stock that we issue is accompanied by the right,
under specified circumstances, to purchase one share of Class A Common Stock at
a price of $150.00, subject to adjustments. The rights will expire on August 25,
2007, unless this date is extended by us or unless we have already redeemed the
rights. Until the distribution date:

     - the rights are not exercisable,

     - the rights can only be transferred with the Class A Common Stock and/or
       Class B Common Stock, and

     - the stock certificates representing shares of our Class A Common Stock
       and Class B Common Stock also represent the rights attached to our Class
       A Common Stock and Class B Common Stock.

     The distribution date is the date, after the date of the rights agreement,
that is the earliest of:

     - ten business days following a public announcement that a person or group
       of affiliated or associated persons has acquired, or obtained the right
       to acquire, beneficial ownership of 15% or more of the Class A Common
       Stock, other than:

      - us and certain related entities;

      - Darwin Deason and certain entities related to him; and

      - any person or group of affiliated or associated persons who acquires 15%
        or more:

        - inadvertently and subsequently divest the excess stock over 14.9%,

        - through a reduction in the number of outstanding shares of Class A
          Common Stock by our board of directors, including a majority of those
          directors not associated with the person or group of affiliated or
          associated persons, and the person or group of affiliated or
          associated persons does not acquire any additional shares, or

                                        13
   20

        - through a stock acquisition or tender or exchange offer pursuant to a
          definitive agreement approved by our board of directors, including a
          majority of those directors not associated with the acquiring person
          or group of affiliated or associated persons, prior to the execution
          of the agreement or the public announcement of the offer; or

     - ten business days following the commencement of, or announcement of an
       intention to make, a tender offer or exchange offer, the consummation of
       which would result in the beneficial ownership by a person or group of
       15% or more of such outstanding Class A Common Stock.

     Pursuant to the terms of the rights agreement, the rights separate from the
shares of our common stock on the distribution date. The rights of the person or
group that triggered the distribution date will be void. As soon as practical
after the distribution date, we will mail the holders of record certificates
representing the rights. The rights will become exercisable to purchase either
the number of shares of Class A Common Stock or the common stock of the
acquiring company, as applicable, having a market value of two times the
applicable exercise price of the right. The exercise price at the time of the
plan's creation was $150.00, however the exercise price and the number of shares
that are evidenced by each right are subject to adjustment from time to time as
set forth in the rights agreement in order to prevent dilution. After the
distribution date but before any person or group of affiliated or associated
persons has acquired, or obtained the right to acquire, beneficial ownership of
50% or more of the Class A Common Stock, our board of directors may exchange the
rights, other than the rights of the person or group of affiliated or associated
persons that triggered the distribution date, in whole or in part, at an
exchange ratio of one share of Class A Common Stock per right, subject to
adjustment.

     Unless the rights have expired or been redeemed or exchanged, they may be
exercised after the distribution date at the option of the holders as provided
in the rights agreement. Until a right is exercised, the holder of the right
will have no rights as a stockholder of us, including, without limitation, the
right to vote, or to receive dividends.

     Under certain conditions set forth in the rights agreement, our board of
directors may, at its option, direct us to redeem the rights in whole, but not
in part, at a price of $0.01 per right. In addition, our board of directors may
extend or reduce the period during which the rights are redeemable, so long as
the rights are redeemable at the time of such extension or reduction.
Immediately upon any redemption of the rights, the right to exercise the rights
will terminate and the only right of the holders of rights will be to receive
the redemption price.

     Our board of directors may amend or supplement the terms of the rights
without the consent of the holders, including an amendment to extend the date on
which the rights expire, except that from and after the distribution date no
such amendment may adversely affect the basic economic interests of the holders
of the rights.

     The rights agreement is intended to protect our stockholders in the event
of an unsolicited attempt to acquire us. Our rights could prevent or delay a
takeover of us by causing substantial dilution to a person or group that
attempts to acquire us on terms not approved by our board of directors. Our
rights should not interfere with any merger or other business combination
approved by our board of directors, since our stockholder rights may be redeemed
by us for a price of $0.01 per rights as described above.

PREFERRED STOCK

     We have no preferred stock outstanding. This section describes the general
terms and provisions of the preferred stock that we may offer by this
prospectus. We may issue preferred stock in one or more series. Each series of
preferred stock will have its own rights and preferences. We will describe in a
prospectus supplement:

     - the specific terms of the series of any preferred stock offered through
       this prospectus, and

     - any general terms outlined in this section that will not apply to those
       shares of preferred stock.

                                        14
   21

This summary of terms is not complete. For additional information before you buy
any preferred stock, you should read our certificate of incorporation and bylaws
that are in effect on the date that we offer any preferred stock, as well as any
applicable amendment to our charter designating terms of a series of preferred
stock.

     Under our certificate of incorporation, we have the authority to issue up
to 3,000,000 shares of preferred stock. Prior to issuing shares of preferred
stock of a particular series, our board of directors will determine or fix the
terms of that series of preferred stock, including:

     - voting rights,

     - redemption provisions,

     - conversion rights,

     - dividend rights,

     - any sinking fund provisions,

     - any transfer restrictions, and

     - preferences in liquidation.

     When we issue shares of preferred stock, they will be fully paid and
nonassessable. This means the full purchase price for the outstanding preferred
stock will be paid at issuance and that you and the purchaser of those shares of
preferred stock will not be required later to pay us any additional amount for
that preferred stock. The preferred stock will have no preemptive rights to
subscribe for any additional securities that we may issue in the future. This
means that purchasers will not receive any rights to buy any portion of the
securities that we may issue in the future.

     Because our board of directors has the power to establish the preferences
and rights of each class or series of preferred stock, our board of directors
may grant the holders of any series or class of preferred stock preferences,
powers and rights senior to the rights of holders of shares of our common stock.
It is not possible to state the actual effect of the authorization and issuance
of additional series of preferred stock upon the rights of holders of our common
stock until our board of directors determines the specific terms, rights and
preferences of a series of preferred stock. These effects might include, among
other things:

     - granting the holders of preferred stock priority over the holders of our
       common stock with respect to the payment of dividends;

     - diluting the voting power of our common stock; or

     - granting the holders of preferred stock preference with respect to
       liquidation rights.

In addition, the issuance of preferred stock may, under some circumstances,
render more difficult or tend to discourage a merger, tender offer or proxy
contest, the assumption of control by a holder of a large block of our
securities or the removal of incumbent management.

CERTIFICATE OF INCORPORATION AND BYLAWS

     Our certificate of incorporation and bylaws contain several provisions that
may be deemed to have an anti-takeover effect and may delay, defer or prevent a
tender offer or takeover attempt. Among other things, these provisions require:

     - 80% vote of stockholders to amend some provisions of our certificate of
       incorporation or our bylaws;

     - permit only our chairman, president or a majority of our board of
       directors to call stockholder meetings; and

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

                                        15
   22

     Our certificate of incorporation does not provide for cumulative voting.
Any action required or permitted to be taken by our stockholders may be taken at
a duly called annual or special meeting of stockholders. The bylaws provide that
special meetings of the stockholders may be called only by the chairman of the
board of directors, the president or a majority of the members of the board of
directors. These provisions could have the effect of delaying until the next
annual stockholders' meeting actions that are not favored by the holders of a
majority of the voting power of our outstanding capital stock. Moreover, the
bylaws authorize the stockholders to take action by written consent signed by
the holders of a majority of the voting power of our outstanding capital stock,
provided that written notice is given to those stockholders who have not
consented in writing.

     Under the Delaware General Corporation Law, the approval of a Delaware
corporation's board of directors, in addition to stockholder approval, is
required to adopt any amendment to the company's certificate of incorporation,
but the exclusive power to adopt, amend and repeal the bylaws is conferred
solely upon the stockholders, unless the corporation's certificate of
incorporation also confers the power on its board of directors. Our certificate
of incorporation grants the power to amend the bylaws to the board of directors.
Our certificate of incorporation also contains provisions permitted under the
Delaware General Corporation Law that limit the liability of directors.

     In addition to these provisions of the certificate of incorporation and
bylaws, we are subject to the provisions of Section 203 of the Delaware General
Corporation Law, which restricts the consummation of some business combination
transactions, including mergers, stock and asset sales and other transactions
resulting in financial benefit to the stockholder, between a Delaware public
corporation and an "interested stockholder" for a period of three years after
the date the interested stockholder acquired its stock. An "interested
stockholder" is defined as a person who, together with any of the person's
affiliates and/or associates, beneficially owns 15% or more of any class or
series of stock entitled to vote in the election of directors. However, a person
is not an "interested stockholder" if:

     - the transaction is approved by (1) the corporation's board of directors
       prior to the date the interested stockholder acquired the shares or (2) a
       majority of the board of directors and by the affirmative vote of the
       holders of two-thirds of the outstanding shares of each class or series
       of stock entitled to vote generally in the election of directors, not
       including the shares owned by the interested stockholder; or

     - the interested stockholder acquired at least 85% of the voting stock of
       the corporation in the transaction in which it became an interested
       stockholder.

     Section 203 of the Delaware General Corporation Law is intended to
discourage some takeover practices by impeding the ability of a hostile acquirer
to engage in some types of transactions with the target company. Moreover, the
bylaws contain a provision that permits any contract or other transaction
between ACS and any of our directors, officers or stockholders, or any
corporation or firm in which any of them are directly or indirectly interested,
to be valid notwithstanding the presence of the director, officer or stockholder
at the meeting authorizing the contract or transaction, or his participation or
vote in the stockholder's meeting or authorization, subject to conditions,
including disclosure.

TRANSFER AGENT AND REGISTRAR

     First City Transfer Company, our affiliate, serves as transfer agent and
registrar for the Class A Common Stock and preferred stock.

NEW YORK STOCK EXCHANGE LISTING

     Our Class A Common Stock is listed for trading on the New York Stock
Exchange under the symbol "ACS".

                        DESCRIPTION OF DEPOSITARY SHARES

     We have no depositary shares outstanding. We may issue depositary receipts
for depositary shares, each of which will represent a fractional interest of a
share of a particular series of preferred stock, as specified in the applicable
prospectus supplement. Shares of preferred stock of each series represented by
depositary shares will be deposited under a separate deposit agreement among us,
the depositary named in the deposit agreement and the holders from time to time
of the depositary receipts. You are encouraged to read the deposit agreement and
depositary receipts.

     Subject to the terms of the deposit agreement, each owner of a depositary
receipt will be entitled, in proportion to the fractional interest of a share of
a particular series of preferred stock represented by the depositary shares
evidenced by the depositary receipt he owns, to all the rights and preferences
of the preferred stock represented by the depositary shares, including:

     - dividend rights,

     - voting rights,

     - conversion rights,

     - redemption rights, and

     - liquidation rights.

     The depositary shares will be evidenced by depositary receipts issued
pursuant to the applicable deposit agreement. Immediately following us issuing
and delivering the preferred stock to the preferred stock depositary, we will
cause the preferred stock depositary to issue, on our behalf, the depositary
receipts. A prospectus supplement will include the form of deposit agreement and
depositary receipt. These documents will include the provisions described in
this prospectus.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The preferred stock depositary will distribute all cash dividends or other
cash distributions received relating to the preferred stock to the record
holders of depositary receipts evidencing the related depositary shares in
proportion to the number of depositary receipts owned by those holders, subject
to some obligations of holders to:

     - file proofs, certificates and other information; and

     - pay some charges and expenses to the preferred stock depositary.

In the event of a distribution other than in cash, the preferred stock
depositary will distribute property received by it to the record holders of
depositary receipts entitled to the distribution, subject to some obligations of
holders to:

     - file proofs, certificates and other information; and

     - pay some charges and expenses to the preferred stock depositary, unless
       the preferred stock depositary determines that it is not feasible to make
       those distributions, in which case the preferred stock depositary may,
       with our approval, sell the property and distribute the net proceeds from
       the sale to holders of the relevant depositary receipts. No distribution
       will be made relating to any depositary share to the extent that it
       represents any preferred stock converted into other securities.

WITHDRAWAL OF STOCK

     Upon surrender of the depositary receipts at the corporate trust office of
the preferred stock depositary (unless the related depositary shares have
previously been called for redemption or converted into other securities), the
holders of those depositary receipts will be entitled to delivery at the
corporate trust office, to or upon that holder's order, the number of whole or
fractional shares of the preferred stock and any money or other property
represented by the depositary shares evidenced by the depositary receipts owned

                                        17
   24

by the holder. Holders of depositary receipts will be entitled to receive whole
or fractional shares of the related preferred stock on the basis of the
proportion of preferred stock represented by the depositary share surrendered as
specified in the applicable prospectus supplement. However, holders of shares of
preferred stock will not thereafter be entitled to receive depositary shares for
such stock. If the depositary receipts delivered by the holder evidence a number
of depositary shares in excess of the number of depositary shares representing
the number of shares of preferred stock to be withdrawn, the preferred stock
depositary will deliver to the holder surrendering the depositary receipt at the
same time a new depositary receipt evidencing the excess number of depositary
shares.

REDEMPTION OF DEPOSITARY SHARES

     Whenever we redeem shares of preferred stock held by the preferred stock
depositary, the preferred stock depositary will redeem as of the same redemption
date the number of depositary shares representing shares of the preferred stock
so redeemed, provided we shall have paid in full to the preferred stock
depositary the redemption price of the preferred stock to be redeemed plus an
amount equal to any accrued and unpaid dividends thereon to the date fixed for
redemption. The redemption price per depositary share will be equal to the
corresponding proportion of the redemption price and any other amounts per share
payable with respect to the preferred stock. If fewer than all the depositary
shares are to be redeemed, the depositary shares to be redeemed will be selected
pro rata (as nearly as may be practicable without creating fractional depositary
shares) or by any other equitable method determined by us.

     From and after the date fixed for redemption, all dividends in respect of
the shares of preferred stock called for redemption will cease to accrue, the
depositary shares called for redemption will no longer be deemed to be
outstanding. At such time, all rights of the holders of the depositary receipts
evidencing the depositary shares called for redemption will cease, except the
right to receive any moneys payable upon redemption of the depositary receipts
and any money or other property to which the holders of the depositary receipts
redeemed were entitled upon redemption and surrender, which moneys or other
property will be paid to the preferred stock depositary.

VOTING OF PREFERRED STOCK

     Upon receipt of notice of any meeting at which the holders of the preferred
stock are entitled to vote, the preferred stock depositary will mail the
information contained in such notice of meeting to the record holders of the
depositary receipts evidencing the depositary shares which represent such
preferred stock. Each record holder of depositary receipts evidencing depositary
shares on the record date (which will be the same date as the record date for
the preferred stock) will be entitled to instruct the preferred stock depositary
as to the exercise of the voting rights pertaining to the amount of preferred
stock represented by each holder's depositary shares. The preferred stock
depositary will vote the amount of preferred stock represented by the depositary
shares in accordance with the instructions provided by the holder of the
depositary shares. We will agree to take all reasonable action which may be
deemed necessary by the preferred stock depositary in order to enable the
preferred stock depositary to vote in accordance with the instructions provided
by the holders.

     The preferred stock depositary will abstain from voting the amount of
preferred stock represented by depositary shares to the extent it does not
receive specific instructions from the holders of depositary receipts evidencing
the depositary shares. The preferred stock depositary shall not be responsible
for any failure to carry out any instruction to vote, or for the manner or
effect of any such vote made, as long as such action or non-action is in good
faith and does not result from negligence or willful misconduct of the preferred
stock depositary.

LIQUIDATION PREFERENCE

     In the event of our liquidation, dissolution or winding up, whether
voluntary or involuntary, the holders of each depositary receipt will be
entitled to the fraction of the liquidation preference accorded

                                        18
   25

each share of preferred stock represented by the depositary shares evidenced by
the respective depositary receipt, as set forth in the applicable prospectus
supplement.

CONVERSION OF PREFERRED STOCK

     The depositary shares will not be convertible into common stock or any
other of our securities or property. Nevertheless, if available, the depositary
receipts may be surrendered by holders of the depositary receipts to the
preferred stock depositary with written instructions to the preferred stock
depositary to instruct us to cause conversion of the preferred stock represented
by the depositary shares evidenced by the depositary receipts surrendered into
whole shares of common stock, other shares of our preferred stock or other
shares of stock. We have agreed that upon receipt of instructions to convert and
any amounts payable in respect of the conversion, we will cause the conversion
of depositary receipts utilizing the same procedures as those provided for
delivery of preferred stock to effect conversion of the depositary receipts. If
the depositary shares evidenced by a depositary receipt are to be converted in
part only, a new depositary receipt or receipts will be issued for any
depositary shares not to be converted. No fractional shares of common stock will
be issued upon conversion, and if conversion would result in a fractional share
being issued, an amount will be paid in cash by us equal to the value of the
fractional interest based upon the closing price of the common stock on the last
business day prior to the conversion.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     The form of depositary receipt evidencing the depositary shares that
represent the preferred stock and any provision of the deposit agreement may at
any time be amended by agreement between us and the preferred stock depositary.
However, any amendment that materially and adversely alters the rights of the
holders of depositary receipts or that would be materially and adversely
inconsistent with the rights granted to the holders of the related preferred
stock will not be effective unless the amendment has been approved by the
existing holders of at least sixty-six and two-third percent (66 2/3%) of the
depositary shares evidenced by the depositary receipts then outstanding. No
amendment will impair the right, subject to some exceptions in the deposit
agreement, of any holder of depositary receipts to surrender any depositary
receipt with instructions to deliver to the holder the related preferred stock
and all money and other property, if any, represented thereby, except in order
to comply with law. Every holder of an outstanding depositary receipt at the
time any amendment becomes effective will be deemed, by continuing to hold such
receipt, to consent and agree to the amendment and to be bound by the deposit
agreement as amended by such amendment.

     The deposit agreement may be terminated by us upon not less than 30 days'
prior written notice to the preferred stock depositary if the holders of a
majority of each series of preferred stock affected by the termination consents
to the termination. Upon a termination that has been consented to, the preferred
stock depositary will deliver or make available to each holder of depositary
receipts, upon surrender of the depositary receipts held by the holder, the
number of whole or fractional shares of preferred stock as are represented by
the depositary shares evidenced by the depositary receipts surrendered by the
holder together with any other property held by the preferred stock depositary
with respect to the depositary receipts surrendered by the holder. In addition,
the deposit agreement will automatically terminate if:

     - all outstanding depositary shares have been redeemed;

     - there has been a final distribution in respect of the related preferred
       stock in connection with any liquidation, dissolution or winding up of
       ACS and the distribution has been distributed to the holders of
       depositary receipts evidencing the depositary shares representing such
       preferred stock; or

     - each share of the related preferred stock has been converted into our
       securities not represented by depositary shares.

CHARGES OF PREFERRED STOCK DEPOSITARY

     We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the deposit agreement. In addition, we will pay the
fees and expenses of the preferred stock depositary in connection with the
performance of its duties under the deposit agreement. However, holders of
depositary receipts will pay the fees and expenses of the preferred stock
depositary for any duties requested by those holders to be performed which are
outside of those expressly provided for in the deposit agreement.

RESIGNATION AND REMOVAL OF PREFERRED STOCK DEPOSITARY

     The preferred stock depositary may resign at any time by delivering to us
notice of its election to do so, and we may at any time remove the preferred
stock depositary. Any resignation or removal of the preferred stock depositary
will take effect upon the appointment of a successor preferred stock depositary.
A successor preferred stock depositary must be appointed within 60 days after
delivery of the notice of resignation or removal and must be a bank or trust
company having its principal office in the United States and having a combined
capital and surplus of at least $50,000,000.

MISCELLANEOUS

     The preferred stock depositary will forward to holders of depositary
receipts any reports, notices, proxy soliciting materials or other
communications from us that are received by the preferred stock depositary with
respect to the related preferred stock. Neither the preferred stock depositary
nor us will be liable if it is prevented from or delayed in performing its
obligations under the deposit agreement, by law or any circumstances beyond its
control. Our obligations and the obligations of the preferred stock depositary
under the deposit agreement will be limited to performing their duties under the
deposit agreement in good faith and without negligence (in the case of any
action or inaction in the voting of preferred stock represented by the
depositary shares), gross negligence or willful misconduct, and we and the
preferred stock depositary will not be obligated to prosecute or defend any
legal proceeding in respect of any depositary receipts, depositary shares or
shares of preferred stock represented thereby unless satisfactory indemnity is
furnished.

     We and the preferred stock depositary may rely on written advice of counsel
or accountants, or information provided by persons presenting shares of
preferred stock represented by the depositary receipts for deposit, holders of
depositary receipts or other persons believed in good faith to be competent to
give information to us and the preferred stock depositary, and on documents
believed in good faith to be genuine and signed by a proper party. In the event
the preferred stock depositary receives conflicting claims, requests or
instructions from any holders of depositary receipts, on the one hand, and us,
on the other hand, the preferred stock depositary will be entitled to act on
those claims, requests or instructions received from us.

offered thereby. Warrants may be exercised at any time up to the close of

warrants will become void.

     Warrants may be exercised as set forth in the applicable prospectus
supplement. Upon receipt of payment and the warrant certificate properly
completed and duly executed at the corporate trust office of the warrant agent
or any other office indicated in the applicable prospectus supplement, we will,
as soon as practicable, forward the debt securities, or shares of preferred
stock or Class A Common Stock purchasable upon exercise of the warrant. If less
than all of the warrants represented by a warrant certificate are exercised, a
new warrant certificate will be issued for the remaining warrants.

                             SELLING SECURITYHOLDER

     Darwin Deason founded ACS in 1988 and until February 1999 served as our
chairman and chief executive officer. Since February 1999, he has continued to
serve as the chairman of our board of directors. As of August 24, 2001 he owned
beneficially 1,504,562 shares of our Class A Common Stock and all 3,299,686
shares of our outstanding Class B Common Stock.

     The following table sets forth information with respect to Mr. Deason's
beneficial ownership of Class A Common Stock, as adjusted to reflect the sale by
Mr. Deason of up to 1,504,562 shares of Class A Common Stock registered for sale
by the registration statement of which this prospectus is a part.

                              PLAN OF DISTRIBUTION

     We may sell the securities described in this prospectus in and outside the
United States (a) through underwriters or dealers, (b) directly to purchasers,
including our affiliates, (c) through agents or (d) through a combination of any
of these methods. The prospectus supplement will include the following
information:

     - the terms of the offering,

     - the names of any underwriters or agents,

     - the name or names of any managing underwriter or underwriters,

     - the purchase price of the securities from us,

     - the net proceeds to us from the sale of the securities,

     - any delayed delivery arrangements,

     - any underwriting discounts, commissions and other items constituting
       underwriters' compensation,

     - any initial public offering price,

     - any discounts or concessions allowed or reallowed or paid to dealers, and

     - any commissions paid to agents.

SALE THROUGH UNDERWRITERS OR DEALERS

     If we use underwriters in the sale, the underwriters will acquire the
securities for their own account. The underwriters may resell the securities
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
prior to or at the time of sale, including at prevailing market prices or at
prices related to prevailing market prices. Underwriters may offer securities to
the public either through underwriting syndicates represented by one or more
managing underwriters or directly by one or more firms acting as underwriters.
Unless we inform you otherwise in the prospectus supplement, the obligations of
the underwriters to purchase the securities will be subject to certain
conditions, and the underwriters will be obligated to purchase all the offered
securities if they purchase any of them. The underwriters may change from time
to time any initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers.

     During and after an offering through underwriters, the underwriters may
purchase and sell the securities in the open market. These transactions may
include overallotment and stabilizing transactions and purchases to cover
syndicate short positions created in connection with the offering. The
underwriters may also impose a penalty bid, which means that selling concessions
allowed to syndicate members or other broker-dealers for the offered securities
sold for their account may be reclaimed by the syndicate if the offered
securities are repurchased by the syndicate in stabilizing or covering
transactions. These activities may stabilize, maintain or otherwise affect the
market price of the offered securities, which may be higher than the price that
might otherwise prevail in the open market. If commenced, the underwriters may
discontinue these activities at any time.

     If we use dealers in the sale of securities, we will sell the securities to
them as principals. They may then resell those securities to the public at
varying prices determined by the dealers at the time of resale. We will include
in the prospectus supplement the names of the dealers and the terms of the
transaction.

DIRECT SALES AND SALES THROUGH AGENTS

     We may sell the securities directly. In this case, no underwriters or
agents would be involved. We may also sell the securities through agents we
designate from time to time. In the prospectus supplement, we will name any
agent involved in the offer or sale of the offered securities, and we will
describe any

                                        23
   30

commissions payable by us to the agent. Unless we inform you otherwise in the
prospectus supplement, any agent will agree to use its reasonable best efforts
to solicit purchases for the period of its appointment.

     We may sell the securities directly to institutional investors or others
who may be deemed to be underwriters within the meaning of the Securities Act of
1933 with respect to any sale of those securities. We will describe the terms of
any such sales in the prospectus supplement.

DELAYED DELIVERY CONTRACTS

     If we so indicate in the prospectus supplement, we may authorize agents,
underwriters or dealers to solicit offers from certain types of institutions to
purchase securities from us at the public offering price under delayed delivery
contracts. These contracts would provide for payment and delivery on a specified
date in the future. The contracts would be subject only to those conditions
described in the prospectus supplement. The prospectus supplement will describe
the commission payable for solicitation of those contracts.

GENERAL INFORMATION

     We may have agreements with the agents, dealers and underwriters to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act of 1933, or to contribute with respect to payments that the
agents, dealers or underwriters may be required to make. Agents, dealers and
underwriters may be customers of, engage in transactions with or perform
services for us in the ordinary course of their businesses.

                                 LEGAL MATTERS

     The validity of the securities will be passed upon for us by Baker Botts
L.L.P., Dallas, Texas.

                             ABOUT THIS PROSPECTUS

     Generally, whenever we use the terms "we," "our," "us," and "ACS," we are
referring to Affiliated Computer Services, Inc. and its subsidiaries. However,
for purposes of the "The Trusts," "Description of the Trust Preferred Securities
Guarantees," and "Description of the Subordinated Debt Securities," sections of
this prospectus, and when the context otherwise requires, the terms "we," "our,"
"us," and "ACS" refer only to Affiliated Computer Services, Inc.

     This prospectus is part of a registration statement we filed with the SEC
using a "shelf" registration process. The registration statement also includes a
prospectus under which we may offer from time to time senior debt securities,
subordinated debt securities, Class A Common Stock, preferred stock, warrants
and depositary securities. Under the shelf registration process, we may offer
from time to time any combination of the securities described in these two
prospectuses in one or more offerings with a total initial offering price of up
to $1,500,000,000. This prospectus provides you with a general description of
the trust preferred securities of ACS Trust I and ACS Trust II, the subordinated
debt securities to be issued by ACS to the trusts, and ACS's guarantee of the
trust preferred securities. Each time we use this prospectus to offer these
securities, we will provide a prospectus supplement that will contain specific
information about the terms of that offering such as:

     - the type and amount of securities which we propose to sell;

     - the initial offering price of such securities;

     - the names and compensation of the underwriters or agents, if any, through
       or to which we will sell the securities;

     - information about any securities exchanges or automated quotation systems
       on which the securities will be listed or traded;

     - any material United States federal income tax considerations applicable
       to the securities; and

     - any other material information about the offering and the sale of the
       securities.

The prospectus supplement may also add, update, or change information contained
or incorporated by reference in this prospectus. Please carefully read this
prospectus and the prospectus supplement, together with the additional
information described under the heading "Where You Can Find More Information."

     We have not included separate financial statements of the trusts in this
prospectus. We do not consider that such financial statements are material to
holders of the trust preferred securities because:

     - each trust is a special purpose entity,

     - neither trust has any operating history or independent operations, and

     - neither trust is engaged in, nor will it engage in, any activity other
       than issuing preferred and common securities, investing in and holding
       our subordinated debt securities and engaging in related activities.

     Furthermore, the combination of our obligations under the subordinated debt
securities, the associated indenture, the declarations of trust and the
guarantees provides a full, irrevocable and unconditional guarantee of payments
of distributions and other amounts due on the trust preferred securities. We do
not expect that the trust will file reports with the SEC under the Securities
Exchange Act of 1934.

                   A WARNING ABOUT FORWARD-LOOKING STATEMENTS

     Statements contained in this prospectus, incorporated by reference in this
prospectus and contained in any accompanying prospectus supplement, that are not
historical facts, are forward-looking statements as defined in the Private
Securities Litigation Reform Act of 1995. These forward-looking statements
include information about possible or assumed future results of our operations.
Also, when we use the words "believes," "expects," "anticipates," "estimates,"
"may," "could," "potential" or similar expressions, we
                                        1
   37

are making forward-looking statements. Many possible events or factors could
affect the future financial results and performance of our company. This could
cause our results or performance to differ materially from those expressed in
our forward-looking statements. You should consider these risks when you
purchase securities.

     The following list identifies some of the factors that could cause our
actual results to differ from those expressed or implied by our forward-looking
statements.

     - our ability to attract and retain skilled personnel,

     - changes in demand for and pricing of information technology outsourcing,
       business process outsourcing, and systems integration services,

     - changes in regulation and governmental or public policy,

     - competition,

     - changes in the financial condition of our customers,

     - general economic conditions, fluctuations in interest rates and
       fluctuations in currency exchange rates in countries in which we do
       business,

     - our ability to complete and integrate strategic acquisitions and
       alliances,

     - changes in the U.S. federal government spending levels for information
       technology services,

     - unexpected operational difficulties or cancellations of significant
       customer contracts, and

     - other factors we discuss in this prospectus, the applicable prospectus
       supplement and our other filings with the SEC.

                       AFFILIATED COMPUTER SERVICES, INC.

     We are a global, Fortune 1000 company delivering comprehensive business
process outsourcing and information technology outsourcing solutions, as well as
system integration services, to both commercial and federal government clients.
We are based in Dallas, Texas and have offices primarily in North America, as
well as Central America, South America, Europe, Africa and the Middle East. Our
clients have time-critical, transaction-intensive information processing needs
and we typically service these needs through long-term contracts.

     We were formed in 1988 to participate in the trend to outsource information
processing requirements to third parties. This outsourcing enables businesses to
focus on core operations, respond to rapidly changing technologies and reduce
expenses associated with business processes and data processing. Our business
strategy is to expand our client base and enhance our service offerings through
both internal marketing and the acquisition of complementary companies. Our
marketing efforts focus on developing long-term relationships with clients that
choose to outsource mission critical business processes and information
technology requirements. Our focus over the last several years has been to
participate in the expanding business process outsourcing market. Our business
expansion has been accomplished both from internal growth as well as through
acquisitions.

     We serve two primary markets. Our largest market is the commercial sector.
Within the commercial sector, which includes state and local governments, we
provide business process outsourcing, systems integration services and
technology outsourcing to a variety of clients nationwide, including healthcare
providers, retailers, local municipalities, state agencies, wholesale
distributors, manufacturers, utilities, financial institutions and insurance
companies.

     We also serve the federal government market. Our services in this market
are comprised of business process outsourcing, systems integration services and
technology outsourcing. Within our federal government business, approximately
half of our revenues are derived from civilian agencies, including the
Department of Education, with the remaining half from Department of Defense
agencies.

     Additional information concerning our business and operations is
incorporated by reference herein from our other SEC filings and may be included
in applicable prospectus supplements.

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

                                USE OF PROCEEDS

     Except as otherwise provided in the applicable supplement to this
prospectus, we expect to use the net proceeds from the sale of the securities we
are offering in this prospectus for general corporate purposes. These purposes
may include:

     - repayment of indebtedness, including indebtedness incurred in connection
       with acquisitions;

     - redemption or repurchase of our securities;

     - additions to working capital;

     - capital expenditures; or

     - acquisitions.

     We will set forth specific information about the use of proceeds from the
sale of the securities in the applicable prospectus supplement. Before any net
proceeds are applied to the uses described above, the proceeds may be invested
in short-term or marketable securities.

     Each trust will use all proceeds from the sale of the trust preferred
securities to purchase our subordinated debt securities.

          ACCOUNTING TREATMENT RELATING TO TRUST PREFERRED SECURITIES

     The financial statements of any trust issuing securities will be
consolidated with our financial statements, with the trust securities shown on
our consolidated financial statements as ACS-obligated mandatorily convertible
preferred trust securities of a subsidiary trust. Our financial statements will
include a footnote that discloses, among other things, that the assets of the
trust consist of our subordinated debt securities and will specify the
designation, principal amount, interest rate and maturity date of such
subordinated debt securities.

                  RATIO OF EARNINGS TO COMBINED FIXED CHARGES
                            AND PREFERRED DIVIDENDS

     The following table sets forth the ratio of earnings to fixed charges for
the periods indicated:



   FISCAL YEAR ENDED JUNE 30,
--------------------------------
1997   1998   1999   2000   2001
----   ----   ----   ----   ----
                
3.9    3.7    4.2    4.6    5.4


     For the purpose of calculating the ratio of earnings to fixed charges,
earnings are defined as earnings before income taxes and extraordinary items
plus fixed charges. Fixed charges consist of interest expense, amortization of
debt issue costs and a portion of rental expense representative of interest.
Since there have been no preferred securities outstanding during the periods
presented, the ratio of earnings to combined fixed charges and preferred
dividends does not differ from the presentation of the ratio of earnings to
fixed charges presented above.

                                   THE TRUSTS

     Each of the trusts was created under the Delaware Business Trust Act and
will be governed by an amended and restated trust agreement between the trustees
of each trust and ACS. Each amended and restated trust agreement will be
qualified under the Trust Indenture Act of 1939.

     We have summarized selected provisions of the amended and restated trust
agreement below. This summary is not complete. For a complete description, we
encourage you to read the applicable form of amended and restated trust
agreement, which we have filed with the SEC. Please read "Where You Can Find
More Information."

     The address of the principal office of each trust is 2828 North Haskell
Avenue, Dallas, Texas 75204. The telephone number at that location is (214)
841-6111.

SECURITIES OF EACH TRUST

     When a trust issues its preferred securities, you and the other holders of
the preferred securities will own all of the issued and outstanding preferred
securities of the trust, representing an undivided beneficial interest in the
assets of each trust. ACS will acquire all of the issued and outstanding common
securities of each trust, representing an undivided beneficial interest in the
assets of each trust of at least 3%. The preferred securities will be
substantially identical to the common securities and will rank equally with the
common securities, except that:

     - if an event of default under the trust agreement occurs and is
       continuing, the holders of preferred securities will have the right to
       receive payments before the holders of the common securities receive
       payments; and

     - the holders of common securities have the exclusive right to increase or
       decrease the number of trustees, or to appoint, remove or replace the
       trustees and to increase or decrease the number of trustees.

     Each trust will exist primarily for the purposes of:

     - issuing its preferred and common securities,

     - investing the proceeds from the sale of its preferred and common
       securities in the subordinated debt securities of ACS, and

     - engaging in only such other activities as are necessary or incidental to
       issuing its securities and purchasing and holding subordinated debt
       securities of ACS.

     The rights of the holders of the preferred securities of a trust, including
economic rights, rights to information and voting rights, will be contained in
and governed by the applicable trust agreement, the Delaware Business Trust Act
and the Trust Indenture Act of 1939.

POWERS AND DUTIES OF TRUSTEES

     The number of trustees of each trust initially will be three. Two of the
trustees will be individuals who are officers or employees of ACS. The third
trustee will be Wilmington Trust Company, a Delaware banking corporation which
has its principal place of business in the State of Delaware, which is
unaffiliated with us and which will serve as the property trustee under the
trust agreement for purposes of the Trust Indenture Act of 1939.

     The property trustee will own and hold for your benefit the subordinated
debt securities purchased by a trust. The property trustee will also:

     - generally exercise the rights, powers and privileges of a holder of the
       subordinated debt securities;

     - maintain exclusive control of a segregated non-interest bearing bank
       account to hold all payments on the subordinated debt securities; and

                                        4
   40

     - promptly make distributions to the holders of the trust securities out of
       funds from the property account.

     Wilmington Trust Company, acting in its capacity as guarantee trustee, will
hold for your benefit a preferred securities guarantee, which will be separately
qualified under the Trust Indenture Act of 1939.

     Because ACS will own all of the common securities of each trust, ACS will
have the exclusive right to appoint, remove or replace trustees and to increase
or decrease the number of trustees. In most cases, there will be at least three
trustees. The term of a trust will be described in the applicable prospectus
supplement, but a trust may dissolve earlier as provided in the applicable trust
agreement.

     The duties and obligations of the trustees of a trust will be governed by
the trust agreement of that trust, the Delaware Business Trust Act and the Trust
Indenture Act of 1939.

BOOKS AND RECORDS

     The books and records of each trust will be maintained at the principal
office of the trust and will be open for inspection by each holder of preferred
securities of the trust or any authorized representative for any purpose
reasonably related to the holder's interest in the trust during normal business
hours.

THE PROPERTY TRUSTEE

     The property trustee, for the benefit of the holders of the trust
securities, generally will exercise all rights under the indenture for the
holders of the subordinated debt securities deposited in the trust as trust
assets, including the right to enforce ACS's obligations under the subordinated
debt securities upon the occurrence of an event of default under the indenture.

     If ACS extends the interest payment period for the related subordinated
debt securities held by a trust and, as a result, the trust does not make
distributions, the property trustee will not be able to enforce the payment of
distributions on the preferred securities until an event of default under the
trust agreement has occurred. If an event of default under the trust agreement
has occurred and is continuing, then the holders of at least a majority of
outstanding preferred securities of a trust may direct the property trustee for
such trust or the guarantee trustee, as the case may be, to enforce the
available remedies under the related trust agreement and preferred securities
guarantee. If the property trustee fails to enforce its rights under the
applicable series of subordinated debt securities, you may provide written
notice to the property trustee that you will enforce those rights and, to the
extent permitted by applicable law, 30 days after submitting that request, you
may, to the extent permitted by applicable law, enforce those rights directly
against ACS without first instituting any legal proceeding against the property
trustee or any other person.

     If an event of default under the applicable trust agreement has occurred
and is continuing and results from ACS's failure to make payments on the
applicable series of subordinated debt securities when due, then you may
directly institute a proceeding to enforce payment of the principal of, any
premium or interest on or any additional amounts payable with respect to the
applicable series of subordinated debt securities in an amount corresponding to
the aggregate liquidation amount of your trust preferred securities. If you
bring any such direct action, ACS will be entitled to your rights under the
applicable trust agreement to the extent of any payment made by ACS to you.
Except as expressly provided in the preceding sentences or in the applicable
prospectus supplement, you will not be able to exercise directly any other
remedy available to the holders of the applicable series of subordinated debt
securities.

EVENTS OF DEFAULT

     If an event of default under the subordinated debt indenture occurs and is
continuing, an event of default under the related trust agreement will occur and
be continuing. In that case, each trust agreement provides that the holders of
common securities will waive any such event of default under the trust agreement
of such trust until all events of default under the trust agreement of such
trust relating to the preferred securities of the trust have been cured, waived
or otherwise eliminated. Until all such events of default under the trust
agreement of such trust relating to the preferred securities have been cured,
waived
                                        5
   41

or otherwise eliminated, the property trustee will act solely on behalf of the
holders of the preferred securities, and only the holders of the preferred
securities will have the right to direct the property trustee as to some matters
under the amended and restated trust agreement and under the indenture relating
to the subordinated debt securities.

     If the holders of the preferred securities of a trust waive any event of
default under the trust agreement as provided in the amended and restated trust
agreement, ACS, as the holder of the common securities, will also be bound by
the waiver without any further act, vote or consent. The property trustee will
notify you of any notice of default relating to the subordinated debt
securities, unless such default has been cured before the giving of such notice
or the property trustee in good faith determines that the withholding of such
notice is in your interests.

DEBTS AND OBLIGATIONS

     In each trust agreement, ACS has agreed to pay all debts and obligations,
other than payments on the related trust securities, and all costs and expenses
of the applicable trust, including the fees and expenses of its trustees and any
taxes and all costs and expenses of the trust. But ACS will not pay withholding
taxes of the trust, except to the extent we describe in the prospectus
supplement. ACS's obligations under each trust agreement will benefit, and will
be enforceable by, any person to whom any such debts, obligations, costs,
expenses and taxes are owed whether or not such creditor has received notice of
ACS's contractual obligation. Any such creditor may enforce these obligations
directly against ACS, and ACS has irrevocably waived any right or remedy to
require that any such creditor take any action against any trust or any other
person before proceeding against ACS. ACS will be entitled to the benefits of
all rights of a trust relating to any amounts paid to any creditor by ACS.

                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES

TERMS

     Each trust may issue only one series of preferred securities. The terms of
the preferred securities will include those stated in the amended and restated
trust agreement and those made a part of that declaration by the Trust Indenture
Act of 1939. For a complete description of the trust preferred securities, we
encourage you to read the amended and restated trust agreement, a form of which
we have filed with the SEC, before purchasing trust preferred securities. Please
read "Where You Can Find More Information."

     ACS will guarantee the trust preferred securities on a subordinated basis
to the extent described under "Description of the Trust Preferred Securities
Guarantee."

     The prospectus supplement relating to preferred securities being offered
will include specific terms relating to the offering. These terms will include
some or all of the following:

     - the designation of the trust preferred securities;

     - the number of trust preferred securities issued by the trust;

     - the annual distribution rate, the distribution payment dates, the record
       dates for distribution payments and the additional amounts, if any, that
       may be payable with respect to the trust preferred securities;

     - whether distributions will be cumulative and compounding and, if so, the
       dates from which distributions will be cumulative or compounded;

     - the amounts that will be paid out of the assets of the trust to the
       holders of preferred securities upon dissolution, winding-up or
       termination of the trust;

     - any repurchase or redemption provisions;

                                        6
   42

     - any voting rights of the trust preferred securities in addition to those
       required by law;

     - any rights to defer distributions on the trust preferred securities by
       extending the interest payment period on the subordinated debt
       securities; and

     - any other relevant terms, rights, preferences, privileges, limitations or
       restrictions of the trust preferred securities.

VOTING

     You will have limited voting rights, relating only to the modification of
the trust preferred securities and, under specified circumstances, the exercise
of the property trustee's rights as holder of the subordinated debt securities
and the preferred securities guarantee. You will not be able to appoint, remove
or replace trustees or to increase or decrease the number of trustees, because
these rights will be vested exclusively in ACS as the holder of the common
securities of the trust.

DISTRIBUTIONS

     Under each amended and restated trust agreement, the property trustee must
make distributions on the preferred securities of a trust to the extent that the
property trustee has cash on hand in the applicable property account to permit
such payment. The only funds available for distribution to the holders of the
preferred securities of a trust will be those received by the property trustee
on the applicable subordinated debt securities. If ACS does not make payments on
the subordinated debt securities, the property trustee will not make
corresponding distributions on the trust preferred securities. Under each
amended and restated trust agreement, if and to the extent ACS does make
payments on the subordinated debt securities, the property trustee will be
obligated to make distributions on the preferred and common securities of such
trust on a pro rata basis.

     ACS will guarantee payment of distributions on the preferred securities of
a trust as and to the extent described under "Description of the Trust Preferred
Securities Guarantees." A preferred securities guarantee covers distributions
and other payments on the applicable trust preferred securities only if and to
the extent that ACS has made a payment to the property trustee on the applicable
subordinated debt securities. If an event of default under the related amended
and restated trust agreement has occurred and is continuing, any funds available
to make payments will be paid first to you and the other holders of the trust
preferred securities pro rata based on the aggregate liquidation amount of trust
preferred securities held by you and other holders in relation to the aggregate
liquidation amount of all the outstanding trust preferred securities. In that
case, ACS, as the holder of common securities of a trust, would receive payments
only after satisfaction of all amounts owed to the holders of trust preferred
securities.

RECORD HOLDERS

     The trustees of a trust may treat the registered owners of the trust
preferred securities as the holders for purposes of receiving distributions and
for all other purposes. Trust preferred securities will be issued in fully
registered form. Unless we inform you otherwise in a prospectus supplement,
trust preferred securities will be represented by one or more global
certificates registered on the books and records of such trust in the name of a
depository or its nominee. Under each amended and restated trust agreement:

     - The trust and its trustees will be entitled to deal with the depository
       for all purposes, including the payment of distributions and receiving
       approvals, votes or consents under the related trust agreement.

     - Except for provisions in the related trust agreement dealing with the
       issuance of definitive certificates representing the trust preferred
       securities, the trust and its trustees will not have any obligation to
       persons owning a beneficial interest in trust preferred securities
       registered in the name of and held by the depository or its nominee.

                                        7
   43

     - The rights of beneficial owners of trust preferred securities will be
       exercised only through the depository and will be limited to those
       established by law and agreements with the depository and/or its
       participants.

     The depository will receive all notices and communications relating to, and
distributions on, trust preferred securities that are registered in the name of
and held by the depository or its nominee. ACS will disclose in the applicable
prospectus supplement the specific terms of the depository arrangement for the
trust preferred securities of a trust and any additional rights and limitations
of owners of beneficial interests in the global subordinated debt securities.

            DESCRIPTION OF THE TRUST PREFERRED SECURITIES GUARANTEES

     We have summarized selected provisions of the guarantees below. This
summary is not complete. For a complete description, we encourage you to read
the guarantees, a form of which we have filed with the SEC, before purchasing
trust preferred securities. Please read "Where You Can Find More Information."

     ACS will irrevocably and unconditionally agree to pay you in full the
following amounts to the extent not paid by the trust:

     - any accumulated and unpaid distributions and any additional amounts with
       respect to the trust preferred securities and any redemption price for
       trust preferred securities called for redemption by the trust, if and to
       the extent that ACS has made corresponding payments on the subordinated
       debt securities to the property trustee of the trust; and

     - payments upon the dissolution, winding-up or termination of the trust
       equal to the lesser of:

      - the liquidation amount plus all accumulated and unpaid distributions and
        additional amounts on the trust preferred securities to the extent the
        trust has funds legally available for those payments, and

      - the amount of assets of the trust remaining legally available for
        distribution to the holders of trust preferred securities in liquidation
        of the trust.

     Wilmington Trust Company, as guarantee trustee, will hold the guarantee for
the benefit of the holders of preferred securities. ACS may satisfy its
obligation to make a guarantee payment either by making payment directly to the
holders of trust preferred securities or to the guarantee trustee for remittance
to the holders or by causing the applicable trust to make the payment to them.

     Each guarantee is a guarantee from the time of issuance of the applicable
series of trust preferred securities. But the guarantees cover distributions and
other payments on trust preferred securities only if and to the extent that ACS
has made corresponding payments on the subordinated debt securities to the
applicable property trustee. If ACS does not make those corresponding payments
on the subordinated debt securities, the trust will not have funds available for
payments and that trustee will not make distributions on the preferred
securities.

     ACS's obligations under the trust agreement for each trust, the guarantees,
the subordinated debt securities and the associated indenture taken together
will provide a full and unconditional guarantee on a subordinated basis of
payments due on the trust preferred securities.

COVENANTS OF ACS

     In each guarantee, ACS will agree that, as long as any preferred securities
issued by the applicable trust are outstanding, ACS will not make the payments
and distributions described below if:

     - it is in default on its guarantee payments or other payment obligations
       under the related guarantee;

     - any event of default under the applicable trust agreement has occurred
       and is continuing; or

                                        8
   44

     - ACS has elected to defer payments of interest on the related subordinated
       debt securities by extending the interest payment period and that
       deferral period is continuing.

In these circumstances, ACS will agree that it will not:

     - declare or pay any dividends on its capital stock or redeem, purchase,
       acquire or make a distribution or liquidation payment with respect to its
       capital stock other than:

      - dividends or distributions in, options, warrants or rights to subscribe
        for or purchase, shares of its capital stock,

      - transactions relating to a shareholders' rights plan,

      - as a result of a reclassification of its capital stock or the exchange
        or conversion of one class or series of its capital stock for another
        class or series of its capital stock,

      - the payment of accrued dividends and the purchase of fractional share
        interests upon conversion or exchange of its capital stock, or

      - purchases of its shares of common stock related to benefit plans of
        itself or any of its affiliates, dividend reinvestment plans or stock
        purchase plans;

     - make any payments on or repay, repurchase or redeem any ACS debt security
       that ranks equally with or junior to the subordinated debt securities;
       and

     - make any guarantee payments on any guarantee by ACS of the debt
       securities of any of its subsidiaries, other than a payment under a
       guarantee related to a series of the trust preferred securities, if that
       guarantee ranks equally with or junior to the subordinated debt
       securities.

In addition, as long as preferred securities issued by any trust are
outstanding, ACS will agree that it will:

     - remain the sole direct or indirect owner of all the outstanding common
       securities of that trust, except as permitted by the applicable trust
       agreement;

     - permit the common securities of that trust to be transferred only as
       permitted by the trust agreement; and

     - use reasonable efforts to cause that trust to continue to be treated as a
       grantor trust for United States federal income tax purposes, except in
       connection with a distribution of subordinated debt securities to the
       holders of trust preferred securities as provided in the trust agreement,
       in which case the trust would be dissolved.

AMENDMENTS AND ASSIGNMENT

     ACS and the guarantee trustee may amend each guarantee without the consent
of any holder of trust preferred securities if the amendment does not adversely
affect the rights of the holders in any material respect. In all other cases,
ACS and the guarantee trustee may amend each guarantee only with the prior
approval of the holders of at least a majority of outstanding preferred
securities issued by the applicable trust. The manner in which ACS will obtain
that approval will be described in the prospectus supplement.

     ACS may assign its obligations under the guarantees only in connection with
a consolidation, merger or asset sale involving ACS that is permitted under the
indenture governing the subordinated debt securities.

TERMINATION OF THE GUARANTEES

     A guarantee will terminate upon:

     - full payment of the redemption price of all preferred securities of the
       applicable trust;

     - distribution of the related subordinated debt securities, or any
       securities into which those debt securities are convertible (if
       applicable), to the holders of the preferred securities and common
       securities of that trust in exchange for all the securities issued by
       that trust; or

     - full payment of the amounts payable upon liquidation of that trust.

     However, each guarantee will continue to be effective or will be reinstated
if any holder of trust preferred securities must repay any amounts paid on those
trust preferred securities or under the guarantee.

STATUS OF THE GUARANTEES

     ACS's obligation under each guarantee to make guarantee payments will be:

     - unsecured,

     - subordinated and junior in right of payment to all other liabilities of
       ACS, except for liabilities that, by their terms, rank equally with or
       subordinate to ACS's obligations under a guarantee, and

     - senior to all capital stock of ACS.

     ACS's obligations under each guarantee will rank equally with obligations
under other guarantee agreements that ACS may enter into from time to time if
both:

     - the agreements are in substantially the form of the preferred securities
       guarantee and provide for comparable guarantees by ACS of payment on
       preferred securities issued by other trusts or financing vehicles of ACS,
       and

     - the debt relating to those trust preferred securities is subordinated,
       unsecured indebtedness of ACS.

     ACS's obligations under each guarantee will be effectively junior to all
debt and preferred stock of its subsidiaries.

     By your acceptance of the trust preferred securities, you agree to the
subordination provisions and other terms of the related guarantee.

     Each guarantee will be deposited with the guarantee trustee to be held for
your benefit. The guarantee trustee will have the right to enforce the guarantee
on your behalf. In most cases, the holders of a majority of outstanding
preferred securities issued by the applicable trust will have the right to
direct the time, method and place of:

     - conducting any proceeding for any remedy available to the applicable
       guarantee trustee, or

     - exercising any trust or other power conferred upon that guarantee trustee
       under the applicable guarantee.

     Each guarantee will constitute a guarantee of payment and not merely of
collection. This means that the guarantee trustee may institute a legal
proceeding directly against ACS to enforce the payment rights under the
guarantee without first instituting a legal proceeding against any other person
or entity.

     If the guarantee trustee fails to enforce the guarantee or ACS fails to
make a guarantee payment, you may institute a legal proceeding directly against
ACS to enforce your rights under that guarantee without first instituting a
legal proceeding against the applicable trust, the guarantee trustee or any
other person or entity.

PERIODIC REPORTS UNDER GUARANTEES

     ACS will be required to provide annually to the guarantee trustee a
statement as to its performance of its obligations and its compliance with all
conditions under the guarantees. ACS and the guarantee trustee will also provide
any reports required to be delivered by the Trust Indenture Act of 1939.

DUTIES OF GUARANTEE TRUSTEE

     The guarantee trustee normally will perform only those duties specifically
set forth in the applicable guarantee. The guarantees do not contain any implied
covenants. If a default occurs on a guarantee, the guarantee trustee will be
required to use the same degree of care and skill in exercise of its powers
under the guarantee as a prudent person would use under the circumstances in the
conduct of his or her own affairs. The guarantee trustee will exercise any of
its rights or powers under the guarantee at the request or direction of holders
of the applicable series of trust preferred securities only if it is offered
security and indemnity satisfactory to it.

GOVERNING LAW

     New York law will govern the guarantees.

                DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

     ACS may issue to a trust from time to time one or more series of
subordinated debt securities under a subordinated indenture between it and the
indenture trustee. The indenture will be qualified under the Trust Indenture
Act. The indenture does not limit the amount of debt securities that ACS may
issue under the indenture or the amount of additional debt that ACS or any of
its subsidiaries may incur. ACS will issue only one series of subordinated debt
securities to each trust.

     We have summarized selected provisions of the indenture and the debt
securities below. You should read the indenture for more details regarding the
provisions we describe below and for other provisions that may be important to
you. We have filed a form of the indenture with the SEC as an exhibit to the
registration statement of which this prospectus forms a part. Please read "Where
You Can Find More Information."

     In this summary description of the subordinated debt securities, all
references to "ACS," "we" or "us" means Affiliated Computer Services, Inc. only
and does not include its subsidiaries or affiliates, unless the context requires
otherwise.

GENERAL

     The subordinated debt securities will be subordinated to, and thus have a
junior position to, all our other senior debt. In some cases, and as would be
described in a prospectus supplement, a series of our subordinated debt may also
be junior in some respects to a different series of subordinated debt. The
indenture will not limit the amount of debt we may issue under the indenture,
and, unless we inform you otherwise in the prospectus supplement, they will not
limit the amount of other debt or securities we may incur or issue. We may issue
debt securities under an indenture from time to time in one or more series, each
in an amount we authorize prior to issuance.

     We conduct a substantial part of our operations through our subsidiaries,
and our subsidiaries generate a significant part of our operating income and
cash flow. As a result, distributions or advances from our subsidiaries are
important sources of funds to meet our debt service obligations. Contractual
provisions or laws, as well as our subsidiaries' financial condition and
operating requirements, may limit our ability to obtain from our subsidiaries
cash that we need to pay our debt service obligations, including payments on the
debt securities. In addition, holders of the debt securities will have a junior
position to the claims of creditors of our subsidiaries on their assets and
earnings.

                                        11
   47

     Unless we inform you otherwise in the prospectus supplement, the indenture
and the debt securities will not contain:

     - any covenants or other provisions designed to protect holders of the debt
       securities in the event we participate in a highly leveraged transaction;
       or

     - provisions that give holders of the debt securities the right to require
       us to repurchase their securities in the event of a decline in our credit
       rating resulting from a takeover, recapitalization or similar
       restructuring or otherwise.

     The prospectus supplement relating to any series of debt securities being
offered will include specific terms relating to the offering. These terms will
include some or all of the following:

     - the title of the debt securities;

     - the total principal amount of the debt securities;

     - whether a series of subordinated debt is junior in any respects to
       another series of subordinated debt;

     - whether we will issue the debt securities in individual certificates to
       each holder or in the form of temporary or permanent global securities
       held by a depositary on behalf of holders;

     - the date or dates on which the principal of and any premium on the debt
       securities will be payable;

     - any interest rate, the date from which interest will accrue, interest
       payment dates and record dates for interest payments;

     - whether and under what circumstances any additional amounts with respect
       to the debt securities will be payable;

     - the place or places where payments on the debt securities will be
       payable;

     - any provisions for redemption or early repayment;

     - any sinking fund or other provisions that would obligate us to redeem,
       purchase or repay the debt securities prior to maturity;

     - the denominations in which we may issue the debt securities;

     - whether payments on the debt securities will be payable in foreign
       currency or currency units or another form, and whether payments will be
       payable by reference to any index or formula;

     - the portion of the principal amount of the debt securities that will be
       payable if the maturity is accelerated, if other than the entire
       principal amount;

     - any additional means of defeasance of the debt securities, any additional
       conditions or limitations to defeasance of the debt securities or any
       changes to those conditions or limitations;

     - any changes or additions to the events of default or covenants this
       prospectus describes;

     - any restrictions or other provisions relating to the transfer or exchange
       of the debt securities; and

     - any other terms of the debt securities.

     We may sell the debt securities at a discount, which may be substantial,
below their stated principal amount. Those debt securities may bear no interest
or interest at a rate that at the time of issuance is below market rates.

     If we sell any of the debt securities for any foreign currency or currency
unit or if payments on the debt securities are payable in any foreign currency
or currency unit, we will describe in the prospectus supplement the
restrictions, elections, material tax consequences, specific terms and other
information relating to those debt securities and the foreign currency or
currency unit.

SUBSEQUENT DISTRIBUTION TO HOLDERS OF TRUST SECURITIES

     If we issue subordinated debt securities to a trust in connection with the
issuance of preferred and common securities by that trust, those subordinated
debt securities subsequently may be distributed to the holders of the preferred
and common securities either:

     - upon the dissolution of the trust, which may be at our election, or

     - upon the occurrence of events that we will describe in the prospectus
       supplement.

SUBORDINATION

     Our subordinated debt securities will have a junior position to all of our
senior debt. "Senior debt" is defined to include debt not expressed to be
subordinate or junior in right of payment to any other indebtedness of ACS.

     Unless we inform you otherwise in the prospectus supplement, the term
"debt" means:

     - indebtedness for borrowed money;

     - obligations evidenced by bonds, debentures, notes or similar instruments;

     - obligations relating to letters of credit or similar instruments;

     - reimbursement obligations relating to letters of credit and similar
       instruments described in the preceding item;

     - obligations to pay the deferred and unpaid purchase price of property or
       services, except trade payables and accrued expenses incurred in the
       ordinary course of business;

     - capitalized lease obligations;

     - debt of a third party secured by a lien on any asset of ACS;

     - debt of others guaranteed by ACS to the extent of the guarantee; and

     - obligations for claims under derivative products.

Under the subordinated indenture, payment of the principal, interest and any
premium on the subordinated debt securities will generally be subordinated and
junior in right of payment to the prior payment in full of all senior debt.
Further, a series of subordinated debt may be junior in some respects to another
series of subordinated debt. The subordinated indenture will provide that no
payment of principal, interest and any premium on the subordinated debt
securities may be made in the event:

     - we fail to pay the principal, interest, premium or any other amounts on
       any senior debt when due; or

     - we default in performing any other covenant (a "covenant default") in any
       senior debt if the covenant default allows the holders of that senior
       debt to accelerate the maturity of the senior debt they hold.

The indenture will not limit the amount of senior debt that we may incur.

     Unless we inform you otherwise in the prospectus supplement, a covenant
default will prevent us from making payments on the subordinated debt securities
only for up to 179 days after holders of the senior debt give the trustee for
the subordinated debt securities notice of a covenant default.

     Unless provided in a prospectus supplement, any subordinated debt
securities offered pursuant to the subordinated indenture will rank equally in
right of payment with each other and to our $230,000,000 original principal
amount of 4% convertible subordinated notes due March 15, 2005 and our
$316,990,000 original principal amount of 3.50% convertible subordinated notes
due February 15, 2006.

                                        13
   49

     The indenture will prohibit us from making for a specified time period any
payment of principal of or premium, if any, or interest on, or sinking fund
requirements for, the subordinated debt securities during the continuance of any
default in respect of senior debt, unless and until the default on the senior
debt is cured or waived.

     Upon any distribution of our assets in connection with any dissolution,
winding up, liquidation, reorganization, bankruptcy or other similar proceeding
relative to us, our creditors or our property, the holders of our senior debt
will first be entitled to receive payment in full of the principal thereof and
premium, if any, and interest due on the senior debt securities before the
holders of the subordinated debt securities are entitled to receive any payment
of the principal of and premium, if any, or interest on the subordinated debt
securities. Because of this subordination, if we become insolvent, our creditors
who are not holders of our senior debt or of our subordinated debt securities
may recover less, ratably, than holders of our senior debt securities but may
recover more, ratably, than holders of our subordinated debt securities.

     The subordination does not affect our obligation, which is absolute and
unconditional, to pay, when due, principal of, premium, if any, and interest on
the subordinated debt securities. In addition, the subordination does not
prevent the occurrence of any default under the indenture.

GLOBAL CERTIFICATES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that will be deposited with a depository
identified in a prospectus supplement. The specific terms of the depository
arrangements with respect to any debt securities of a series will be described
in a prospectus supplement.

     Unless otherwise specified in a prospectus supplement, debt securities
issued in the form of a global certificate to be deposited with a depository
will be represented by a global certificate registered in the name of the
depository or its nominee. Upon the issuance of a global certificate in
registered form, the depository for the global certificate will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the debt securities represented by the global certificate to the accounts of
institutions that have accounts with the depository or its nominee. The
depository or its nominee are referred to in this prospectus as participants.
The accounts to be credited shall be designated by the underwriters or agents of
the debt securities, or by us if the debt securities are offered and sold
directly by us.

     Ownership of beneficial interests in a global certificate will be limited
to participants or persons that may hold interests through participants.
Ownership of beneficial interests by participants in a global certificate will
be shown on, and the transfer of that ownership interest will be effected only
through, records maintained by the depository or its nominee for the global
certificate. Ownership of beneficial interests in a global certificate by
persons that hold through participants will be shown on, and the transfer of
that ownership interest within a participant will be effected only through,
records maintained by that participant. The laws of some jurisdictions require
that some purchasers of securities take physical delivery of their securities in
definitive form. These limits and laws may impair your ability to transfer
beneficial interests in a global certificate.

     So long as the depository for a global certificate in registered form, or
its nominee, is the registered owner of the global certificate, the depository
or its nominee, as the case may be, will be considered the sole owner or holder
of the debt securities of the series represented by the global certificate for
all purposes under the indenture. Except as set forth below, owners of
beneficial interests in a global certificate will not be entitled to have debt
securities of the series represented by the global certificate registered in
their names, will not receive or be entitled to receive physical delivery of
debt securities in definitive form, and will not be considered the owners or
holders of the global certificate under the indenture.

                                        14
   50

     Payment of principal of, premium, if any, and any interest on debt
securities of a series registered in the name of or held by a depository or its
nominee will be made to the depository or its nominee, as the case may be, as
the registered owner or the holder of a global certificate representing the debt
securities. None of us, the trustee, any paying agent, or the applicable debt
security registrar for the debt securities will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a global certificate for debt securities or
for maintaining, supervising or reviewing any records relating to beneficial
ownership interests.

     We expect that the depository for debt securities of a series, upon receipt
of any payment of principal, premium or interest in respect of a permanent
global certificate, will credit immediately participants' accounts with payments
in amounts proportionate to their respective beneficial interests in the
principal amount of the global certificate as shown on the records of the
depository. We also expect that payments by participants to owners of beneficial
interests in a global certificate held through those participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in street name, and those payments will be the responsibility of the
participants. However, we have no control over the practices of the depository
and/or the participants and there can be no assurance that these practices will
not be changed.

     Unless it is exchanged in whole or in part for debt securities in
definitive form, a global certificate may generally be transferred only as a
whole unless it is being transferred to particular nominees of the depository.

     Unless otherwise stated in any prospectus supplement, The Depository Trust
Company, New York, New York will act as depository. Beneficial interests in
global certificates will be shown on, and transfers of global certificates will
be effected only through, records maintained by The Depository Trust Company and
its participants.

EVENTS OF DEFAULT

     Under the indenture, an event of default, unless a prospectus supplement
provides otherwise, will mean any of the following:

     - our failure to pay principal of or any premium on any debt securities of
       that series when due, regardless of whether such payment became due
       because of maturity, redemption, acceleration or otherwise, or is
       required by any sinking fund established with respect to such series;

     - our failure to pay interest or any required additional amounts on any
       debt securities of that series for 30 days;

     - our failure to comply with any of our covenants or agreements in the debt
       securities of that series or the indenture, other than an agreement or
       covenant that we have included in the indenture solely for the benefit of
       other series of debt securities, for the period of days specified in the
       applicable prospectus supplement after written notice by the trustee or
       by the holders of at least 25% in principal amount of all the outstanding
       debt securities issued under the indenture that are affected by that
       failure;

     - certain defaults with respect to our debt (other than the debt securities
       of that series) in an aggregate principal amount in excess of that dollar
       amount specified in the related prospectus supplement and supplemental
       indenture for the debt securities, which consists of the failure to make
       any payment at maturity or that results in acceleration of the maturity
       of such debt;

     - specified events involving our bankruptcy, insolvency or reorganization;

     - certain events of dissolution or winding up of the trusts; or

     - any other event of default provided for that series of debt securities.

     An event of default for a particular series of debt securities does not
necessarily constitute an event of default for any other series of debt
securities issued under an indenture. The trustee may withhold notice
                                        15
   51

to the holders of debt securities of any default (except in the payment of
principal or interest) if it considers on good faith that the withholding of
notice is in the best interests of the holders.

     If an event of default for any series of debt securities occurs and is
continuing, the trustee or the holders of at least 25% in principal amount of
the outstanding debt securities of the series affected by the default, voting as
one class, may declare the principal of and all accrued and all unpaid interest
on those debt securities to be due and payable. If an event of default relating
to events of bankruptcy, insolvency or reorganization occurs, the principal of
and all accrued and unpaid interest on all the debt securities will become
immediately due and payable without any action on the part of the trustee or any
holder. The holders of a majority in principal amount of the outstanding debt
securities of the series affected by the default, voting as one class, may in
some cases rescind this accelerated payment requirement. Depending on the terms
of our other indebtedness, an event of default under the indenture may give rise
to cross defaults on our other indebtedness.

     The indenture will limit the right to institute legal proceedings. No
holder of any debt securities will have the right to bring a claim under an
indenture unless:

     - the holder has given written notice of a continuing default for that
       series to the trustee;

     - the holders of not less than 25% of the aggregate principal amount of
       debt securities of the series shall have made a written request to the
       trustee to bring the claim and furnished the trustee reasonable
       indemnification as the trustee may require;

     - the trustee has not commenced an action within 60 days of receipt of the
       notice and indemnification; and

     - during the 60-day period following receipt of the notice and
       indemnification, no direction inconsistent with the request has been
       given to the trustee by the holders of not less than a majority of the
       aggregate principal amount of the debt securities of the series then
       outstanding.

Subject to applicable law and any applicable subordination provisions, the
holders of debt securities may enforce payment of the principal of or premium,
if any, or interest on their debt securities.

     Except as provided in the next sentence, the holders of a majority in
aggregate principal amount of any series of debt securities may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee or exercising any power conferred on the trustee. The trustee may
decline to follow the holders' direction if, being advised by counsel, the
trustee determines that the action is not lawful, or if the trustee in good
faith determines that the action would unduly prejudice the holders of the debt
securities not taking part in the action or would impose personal liability on
the trustee.

     The indenture will provide that, in case an event of default in respect of
a particular series of debt securities has occurred, the trustee must use the
degree of care of a prudent man in the conduct of his own affairs. Subject to
these provisions, the trustee is under no obligation to exercise any of its
rights or power under the indenture at the request of any of the holders of the
debt securities of any series unless they have furnished to the trustee
reasonable security or indemnity.

     We will be required to furnish to the trustee an annual statement as to our
fulfillment of all of our obligations under the indenture.

DEFEASANCE

     When we use the term "defeasance," we mean discharge from some or all of
our obligations under an indenture. If we deposit with the applicable trustee
funds or government securities sufficient to make payments on the debt
securities of a series on the dates those payments are due and payable, then, at
our option, either of the following will occur:

     - we will be discharged from our obligations with respect to the debt
       securities of that series ("legal defeasance"); or

                                        16
   52

     - we will no longer have any obligation to comply with the restrictive
       covenants under the indenture, and the related events of default will no
       longer apply to us, but some of our other obligations under the indenture
       and the debt securities of that series, including our obligation to make
       payments on those debt securities, will survive ("covenant defeasance").

     If we effect a covenant defeasance of a series of debt securities, the
holders of the debt securities of the series affected will not be entitled to
the benefits of the indenture, except for our obligations to:

     - register the transfer or exchange of debt securities;

     - replace stolen, lost or mutilated debt securities; and

     - maintain paying agencies and hold moneys for payment in trust.

     Unless we inform you otherwise in the prospectus supplement, we will be
required to deliver to the trustee an opinion of counsel that the deposit and
related defeasance would not cause the holders of the debt securities to
recognize income, gain or loss for United States federal income tax purposes. If
we elect legal defeasance, that opinion of counsel must be based on a ruling
from the United States Internal Revenue Service or a change in law to that
effect.

CONSOLIDATION, MERGER OR SALE OF ASSETS

     The indenture will generally permit us to consolidate or merge with another
entity. The indenture will also permit us to sell all or substantially all of
our property and assets. However, we will only consolidate or merge with or into
any other entity, or sell all or substantially all of our assets, in accordance
with the terms and conditions of the indenture. The indenture provides that we
may consolidate with another entity to form a new entity, or merge into any
other entity, or transfer or dispose of our assets substantially as an entirety
to any other entity only if:

     - the resulting or surviving entity assumes the due and punctual payments
       on the debt securities and the performance of our covenants and
       obligations under the applicable indenture and the debt securities; and

     - immediately after giving effect to the transaction, no default or event
       of default would occur and be continuing.

     The remaining or acquiring entity will be substituted for us in the
indenture with the same effect as if it had been an original party to the
indenture. Thereafter, the successor entity may exercise our rights and powers
under the indenture, in our name or in its own name. Any act or proceeding
required or permitted to be done by our board of directors or any of our
officers may be done by the board or officers of the successor entity.

MODIFICATION AND WAIVER

     We may amend or supplement the indenture if the holders of a majority in
principal amount of the outstanding debt securities of all series issued under
the indenture and affected by the amendment or supplement, acting as one class,
consent to it. Without the consent of the holder of each debt security affected,
however, no amendment or supplement may:

     - reduce the amount of debt securities whose holders must consent to an
       amendment, supplement or waiver;

     - reduce the rate of or change the time for payment of interest on any debt
       security;

     - reduce the principal of, premium on or any mandatory sinking fund payment
       for any debt security;

     - change the stated maturity of any debt security;

     - reduce any premium payable on the redemption of any debt security or
       change the time at which any debt security may or must be redeemed;

                                        17
   53

     - change any obligation to pay additional amounts on any debt security;

     - make the payments on any debt security payable in any currency or
       currency unit other than as the debt security originally states;

     - impair the holder's right to institute suit for the enforcement of any
       payment on any debt security;

     - make any change in the percentage of principal amount of debt securities
       necessary to waive compliance with specified provisions of the indenture
       or to make any change in the indenture's provisions for modification;

     - waive a continuing default or event of default regarding any payment on
       any debt security; or

     - modify the provisions relating to the subordination of any subordinated
       debt security in a manner adverse to the holder of that security.

     We and the trustee may agree to amend or supplement an indenture or waive
any provision of an indenture without the consent of any holders of debt
securities in some circumstances, including:

     - to cure any ambiguity, omission, defect or inconsistency;

     - to provide for the assumption of our obligations under the indenture by a
       successor upon any merger, consolidation or asset transfer;

     - to provide for uncertificated debt securities in addition to or in place
       of certificated debt securities or to provide for bearer debt securities;

     - to provide any security for or add guarantees of any series of debt
       securities;

     - to comply with any requirement to effect or maintain the qualification of
       the indenture under the Trust Indenture Act of 1939;

     - to add covenants that would benefit the holders of any debt securities or
       to surrender any rights we have under the indenture;

     - to add events of default with respect to any debt securities;

     - to make any change that does not adversely affect any outstanding debt
       securities of any series in any material respect;

     - to facilitate the defeasance or discharge of any series of debt
       securities if that change does not adversely affect the holders of debt
       securities of that series or any other series under the indenture in any
       material respect; and

     - to provide for the acceptance of a successor or another trustee.

     The holders of a majority in principal amount of the outstanding debt
securities of any series, or of all debt securities affected, voting as one
class, may waive any existing or past default or event of default with respect
to those debt securities. Those holders may not, however, waive any default or
event of default in any payment on any debt security or compliance with a
provision that cannot be amended or supplemented without the consent of each
holder affected.

CERTIFICATES AND OPINIONS TO BE FURNISHED TO THE TRUSTEE

     The indenture will provide that, in addition to other certificates or
opinions that may be specifically required by other provisions of an indenture,
every time we ask the trustee to take action under the indenture, we must
provide a certificate of some of our officers and an opinion of counsel (who may
be our counsel) stating that, in the opinion of the signers, all conditions
precedent to the action have been complied with.

REPORT TO HOLDERS OF DEBT SECURITIES

     We will provide audited financial statements annually to the trustee. The
trustee will be required to submit an annual report to the holders of the debt
securities discussing, among other things, the trustee's eligibility to serve as
trustee, the priority of the trustee's claims regarding some advances made by
it, and any action taken by the trustee materially affecting the debt
securities.

THE TRUSTEE

     U.S. Trust Company of Texas, N.A. will initially serve as the trustee under
our subordinated indenture.

     U.S. Trust Company of Texas, N.A. will also initially serve as the trustee
under our senior indenture. Pursuant to applicable provisions of the indentures
and the Trust Indenture Act of 1939 governing trustee conflicts of interest, any
uncured event of default with respect to any series of debt securities will
force the trustee to resign as trustee under either the subordinated indentures
or the senior indentures. Any resignation requires the appointment of a
successor trustee under the applicable indenture in accordance with its terms
and conditions.

     The trustee may resign or be removed by us under certain circumstances
specified in the indenture with respect to one or more series of debt securities
and a successor trustee may be appointed to act with respect to any series. The
holders of a majority in aggregate principal amount of the debt securities of
any series may remove the trustee with respect to the debt securities of that
series.

     The indenture will contain limitations on the right of the trustee
thereunder, in the event that the trustee becomes our creditor, to obtain
payment of claims in particular cases or to realize on some property received in
respect of any claim as security or otherwise.

                              PLAN OF DISTRIBUTION

     We may sell the securities described in this prospectus in and outside the
United States (a) through underwriters or dealers, (b) directly to purchasers,
including our affiliates, (c) through agents or (d) through a combination of any
of these methods. The prospectus supplement will include the following
information:

     - the terms of the offering,

     - the names of any underwriters or agents,

     - the name or names of any managing underwriter or underwriters,

     - the purchase price of the securities from us,

     - the net proceeds to us from the sale of the securities,

     - any delayed delivery arrangements,

     - any underwriting discounts, commissions and other items constituting
       underwriters' compensation,

     - any initial public offering price,

     - any discounts or concessions allowed or reallowed or paid to dealers, and

     - any commissions paid to agents.

SALE THROUGH UNDERWRITERS OR DEALERS

     If we use underwriters in the sale, the underwriters will acquire the
securities for their own account. The underwriters may resell the securities
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
prior to or at the time of sale including at prevailing market prices or at
prices related to prevailing market prices.
                                        19
   55

Underwriters may offer securities to the public either through underwriting
syndicates represented by one or more managing underwriters or directly by one
or more firms acting as underwriters. Unless we inform you otherwise in the
prospectus supplement, the obligations of the underwriters to purchase the
securities will be subject to certain conditions, and the underwriters will be
obligated to purchase all the offered securities if they purchase any of them.
The underwriters may change from time to time any initial public offering price
and any discounts or concessions allowed or reallowed or paid to dealers.

     During and after an offering through underwriters, the underwriters may
purchase and sell the securities in the open market. These transactions may
include overallotment and stabilizing transactions and purchases to cover
syndicate short positions created in connection with the offering. The
underwriters may also impose a penalty bid, which means that selling concessions
allowed to syndicate members or other broker-dealers for the offered securities
sold for their account may be reclaimed by the syndicate if the offered
securities are repurchased by the syndicate in stabilizing or covering
transactions. These activities may stabilize, maintain or otherwise affect the
market price of the offered securities, which may be higher than the price that
might otherwise prevail in the open market. If commenced, the underwriters may
discontinue these activities at any time.

     If we use dealers in the sale of securities, we will sell the securities to
them as principals. They may then resell those securities to the public at
varying prices determined by the dealers at the time of resale. We will include
in the prospectus supplement the names of the dealers and the terms of the
transaction.

DIRECT SALES AND SALES THROUGH AGENTS

     We may sell the securities directly. In this case, no underwriters or
agents would be involved. We may also sell the securities through agents we
designate from time to time. In the prospectus supplement, we will name any
agent involved in the offer or sale of the offered securities, and we will
describe any commissions payable by us to the agent. Unless we inform you
otherwise in the prospectus supplement, any agent will agree to use its
reasonable best efforts to solicit purchases for the period of its appointment.

     We may sell the securities directly to institutional investors or others
who may be deemed to be underwriters within the meaning of the Securities Act of
1933 with respect to any sale of those securities. We will describe the terms of
any such sales in the prospectus supplement.

DELAYED DELIVERY CONTRACTS

     If we so indicate in the prospectus supplement, we may authorize agents,
underwriters or dealers to solicit offers from certain types of institutions to
purchase securities from us at the public offering price under delayed delivery
contracts. These contracts would provide for payment and delivery on a specified
date in the future. The contracts would be subject only to those conditions
described in the prospectus supplement. The prospectus supplement will describe
the commission payable for solicitation of those contracts.

GENERAL INFORMATION

     We may have agreements with the agents, dealers and underwriters to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act of 1933, or to contribute with respect to payments that the
agents, dealers or underwriters may be required to make. Agents, dealers and
underwriters may be customers of, engage in transactions with or perform
services for us in the ordinary course of their businesses.

*  The registrants previously filed with the Securities and Exchange Commission
   on November 15, 1999, a shelf registration statement (Registration Number
   333-90943) for the registration of $500,000,000 of securities. No securities
   were sold pursuant to such registration statement and such registration
   statement has been terminated. The filing fee paid by the registrants in
   connection with such prior registration statement is offset, pursuant to Rule
   457(p) of the Securities Act, against the filing fee due in connection with
   this registration statement, resulting in a new net paid filing fee of
   $250,000.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 9 of the Company's Second Amended and Restated Certificate of
Incorporation provides for indemnification of directors and officers to the full
extent permitted under Delaware law.

     Section 145 of the Delaware General Corporation Law empowers a Delaware
corporation to indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director or officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise. The indemnity may include expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by that person in connection with such action, suit or proceeding, provided that
such person acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the corporation and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful. A Delaware corporation may indemnify directors,
officers, employees and others in an action by or in the right of the
corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the person to be indemnified has been
adjudged to be liable to the corporation. Where a director or officer is
successful on the merits or otherwise in the defense of any action referred to
above or in defense of any claim, issue or matter therein, the corporation must
indemnify that director or officer against the expenses (including attorneys'
fees) which he or she actually and reasonably incurred in connection therewith.

     Section 33 of the Company's bylaws provides that the Company will, to the
fullest extent permitted by applicable law as then in effect, indemnify any
person who is or was involved in any manner or is threatened to be made so
involved in any threatened, pending or completed investigation, claim, action,
suit or proceeding, whether civil, criminal, administrative, or investigative
(including, without limitation, any action, suit, or proceeding by or in the
right of the Company to procure a judgment in its favor) by

                                       II-1
   60

reason of the fact that such person is or was or had agreed to become a
director, officer, employee or agent of the Company, or is or was serving at the
request of the Board of Directors or an officer of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, or other enterprise, whether for profit or not for profit, or anything
done or not done by such person in any capacity, against all expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such proceeding. Section 33 of the Company's
bylaws also provides that the Company may provide advances to an indemnitee to
cover expenses he or she incurs in defending against any action, suit,
proceeding or investigation.

     The Company has also entered into indemnification agreements with each of
its directors. These indemnification agreements generally provide the Company's
directors with a contractual right of indemnification to the same extent
provided by Section 145 of the Delaware General Corporation Law and a
contractual right to advancement of expenses consistent with the provisions of
Article IX of the Company's amended and restated bylaws.

     Additionally, the Company's certificate of incorporation, as amended,
contains a provision that eliminates the personal liability of directors to the
Company or its shareholders to the fullest extent allowed by Delaware law for or
with respect to any acts or omissions in the performance of his or her duties as
a director of the Company. As a result, shareholders may be unable to recover
monetary damages against directors for negligent or grossly negligent acts or
omissions in violation of their duty of care. The provision does not change the
liability of a director for breach of his duty of loyalty to the Company or to
shareholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, for the declaration or
payment of dividends in violation of Delaware law, or in respect of any
transaction from which that director receives an improper personal benefit.

     The Company also maintains directors' and officers' liability insurance for
its directors and officers that protects them from certain losses arising from
claims or charges made against them in their capacities as directors or officers
of the Company.

     Agreements the Company may enter into with underwriters, dealers and agents
who participate in the distribution of securities of the Company may contain
provisions relating to the indemnification of the Company's officers and
directors.

ITEM 17. UNDERTAKINGS.

     (a) The undersigned registrants hereby undertake:

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

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933, as amended (the "Securities Act");

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this registration statement. Notwithstanding the foregoing, any
        increase or decrease in the volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

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

     provided, however, that paragraphs (i) and (ii) do not apply if the
     registration statement is on Form S-3, Form S-8 or Form F-3, and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission by the registrants pursuant to Section 13 or 15(d) of the
     Securities Exchange Act of 1934 that are incorporated by reference in the
     registration statement.

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

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

     (b) The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in this registration statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrants pursuant to the indemnification provisions described herein, or
otherwise, the registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrants of expenses incurred or paid by a director, officer
or controlling person of the registrants in the successful defense of any
action, suit, or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrants will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
                                       II-4

     (d) The undersigned registrants hereby undertake that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     (e) The undersigned registrants hereby undertake to file an application for
the purpose of determining the eligibility of the trustee under any indenture
relating to the debt securities to act under subsection (a) of Section 310 of
the Trust Indenture Act of 1939 in accordance with the rules and regulations
prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act
of 1939.
