Darwin Deason and Cerberus Submit Revised Offer for Affiliated Computer Services, Inc.

DALLAS -- Darwin Deason, the founder and Chairman of Affiliated Computer Services, Inc. (NYSE: ACS), today announced that he, together with his investment partner Cerberus Capital Management, L.P., sent the following letter to the board of directors of ACS on Saturday, April 21:

April 21, 2007


Board of Directors
Affiliated Computer Services, Inc.
2828 N. Haskell Avenue
Dallas, Texas 75204

Gentlemen:

    It has been a full month since my investment partner, Cerberus
Capital Management, L.P., and I made our proposal on March 20 to
acquire Affiliated Computer Services, Inc. (the "Company").
Unfortunately, during that time we have made no progress whatsoever,
and the Special Committee has refused to negotiate with us, to permit
Cerberus to conduct essential due diligence or to engage us in any
constructive fashion.

    In a final attempt to show you our good faith and our willingness
to provide the Company's shareholders with full and fair value, we
are hereby increasing our offer to $62.00 in cash per share. Our
increased offer represents nearly a 21% premium over the
pre-announcement closing price and a 24% premium over the 90-day
average closing price. It also represents nearly an 11% increase over
our initial indication of interest at $56.00 and, more importantly, a
5% increase over our publicly announced $59.25 offer. Our $62.00 per
share offer is fully priced and is the highest price we are prepared
to pay based on the information made available to us to date. This
offer is conditioned on the prompt commencement of due diligence and
prompt negotiation of a definitive merger agreement.

    We are convinced that the overwhelming majority of the Company's
shareholders support our transaction with the Company. Accordingly,
in addition to the customary shareholder approval by a majority in
voting power, I will agree, only with respect to my proposal with
Cerberus, to submit the definitive merger agreement for approval by a
majority of the Class A and Class B shares voted on a
one-share-one-vote basis. We are also prepared to have the adequacy
of our price tested by a robust marketing process that would commence
immediately upon our execution of a definitive merger agreement. We
propose a 40-day "go-shop" period following execution of a merger
agreement during which the Company and its advisors would solicit
superior proposals; if a superior proposal is accepted during the
"go-shop" period, we would receive only a break-up fee of 1.5% of the
Company's equity value. Moreover, under the terms of my exclusivity
agreement with Cerberus, I am free to negotiate with any competing
bidders during a post-signing "go-shop" period and to vote my shares
in favor of any superior proposal reached by the Board for the
benefit of ACS shareholders. The terms of the exclusivity agreement
will not obstruct the market check process.

    We believe that these terms are customary for similar
transactions today and will ensure that the interests of the public
shareholders are protected. As you know, a post-signing market check
is a valuable, respected tool to generate shareholder value. The
suggestion to us by the Committee's advisors that equity sponsor-led
transactions never generate topping bids following definitive
agreement is erroneous information which the Committee should reject.
In fact, on many occasions, competing proposals submitted during the
post-signing period have resulted in increased consideration to
shareholders. Equity sponsors have topped other financial buyers
three times this week alone: Catalina Marketing, Aeroflex and
Alliance Boots.

    I wish to reiterate that I personally am committed to the
long-term future of the Company. I plan to continue as Chairman for
at least the next five years, whether or not our proposed acquisition
is consummated. Following the acquisition, I will continue to have an
extremely large economic stake in the Company. As I previously
disclosed, I will roll, into equity securities of the acquiring
entity, Company common stock and options having an aggregate value of
approximately $300 million, and I will receive performance- and
time-based equity incentives going forward. My roll of equity
securities is not an option, it is a continuation of my long-term
commitment to the Company - and you should interpret it as such.

    Since my founding of the Company nearly 20 years, ago, I have
been active as a major shareholder and as Executive Chairman. In
discussions, your advisors have proposed that I be compelled to
accept any transaction approved by the Board of Directors. I will not
accept your advisors' attempts to disenfranchise me and disregard my
rights as a Class B shareholder and under my employment agreement, as
confirmed in the Company's charter. The Company's investors have
purchased their Class A shares with full knowledge of my rights, and
I will not agree to compromise these rights in any way. Any attempt
to create a scenario where my rights are disregarded - as if the
directors were acting as fiduciaries for the shareholders of a
hypothetical company, instead of ACS - ignores the facts and Delaware
law to the detriment of the Company's shareholders.

    We believe that our proposal is in the best interests of the
Company and its public shareholders and that the shareholders will
find the offer attractive. We believe that it is in the interests of
all involved - shareholders, customers, employees and other
stakeholders - that the Board engage with us concerning our offer.
The Board's continuing delay puts the entire Company and our offer at
risk.

                                        Very truly yours,


                                        /s/ Darwin Deason

                                        Darwin Deason
