VOTING AGREEMENT

This VOTING AGREEMENT (the “Agreement”), dated as of February 9, 2006, is made by and between Darwin Deason (the “Principal Stockholder”), and Affiliated Computer Services, Inc., a Delaware corporation (the “Company”).

WHEREAS, the Company is commencing as of the date hereof an issuer tender offer (the “Tender Offer”) under Rule 13e-4 of the Securities Exchange Act of 1934, as amended, for shares of its Class A Common Stock, $0.01 par value (the “Class A Shares”), on the terms specified in the Company’s Schedule TO (as it may be amended or supplemented by the Company from time to time, the “Schedule TO”) filed with the Securities and Exchange Commission as of the date hereof;

WHEREAS, as of the date hereof, the Principal Stockholder owns, with the right to vote, the number of Class A Shares and the number of shares of the Company’s Class B Common Stock, $0.01 par value (the “Class B Shares”) set forth on Schedule A hereto (collectively, the “Owned Shares”), which represent in the aggregate, based on Company share data as of February 5, 2006, approximately 36.89% of the combined voting power of the Company’s outstanding Class A Shares and Class B Shares; and

WHEREAS, as a condition to the willingness of the Company to commence the Tender Offer, the Company has required that the Principal Stockholder enter into this Agreement with respect to Voting Securities (as hereinafter defined) the Principal Stockholder may directly or indirectly own from time to time at or after the Post Closing Determination Time (as hereinafter defined) (the “Subject Shares”), it being understood that Voting Securities shall be Subject Shares only during the period they are so owned.

NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein, the parties hereto agree as follows:

ARTICLE I

VOTING AGREEMENT

SECTION 1.1 Voting Agreement. (a) The Principal Stockholder hereby agrees that during the time this Agreement is in effect, at any meeting of the stockholders of the Company, however called, or at any adjournment or postponement thereof (a “Company Stockholders’ Meeting”), or in any other circumstances upon which a vote, consent or other approval (including by written consent) is sought by or from the stockholders of the Company, the Principal Stockholder shall (x) when a Company Stockholders’ Meeting is held, appear at such Company Stockholders’ Meeting or otherwise cause Subject Shares that represent Excess Voting Power to be counted as present thereat for the purpose of establishing a quorum (except to the extent otherwise provided in the immediately succeeding clause (y) with respect to non-affiliated shares which are not counted as present), and (y) cause Subject Shares that represent Excess Voting Power to be treated in the same manner (i.e., not present (and, therefore, not

counted as present for quorum purposes), present but abstaining, voting for or voting against), and in proportion to, the votes or actions of all Company stockholders, including the vote or actions of the Principal Stockholder and his affiliates on the basis, solely for the purpose of determining proportionality, of one vote per Class A Share and Class B Share (even though the Class B Shares have ten votes per share), at any such Company Stockholders’ Meeting or under any such other circumstances upon which a vote, consent or other approval (including by written consent) is sought by or from the stockholders of the Company. For purposes of this Agreement: (i) “Cap Amount” means the aggregate percentage voting power represented by the Subject Shares of the combined voting power of the outstanding Voting Securities as of the Pre-Closing Determination Time (as hereinafter defined), (ii) “Excess Voting Power” (as calculated as of the Post Closing Determination Time and at such other subsequent times, from time to time, as required by this Agreement) means the aggregate percentage voting power represented by the Subject Shares of the combined voting power of the outstanding Voting Securities less the Cap Amount, adjusted in accordance with the first sentence of Section 1.1(b), (iii) “Pre-Closing Determination Time” means the date and time immediately prior to the Expiration Date (as hereinafter defined), (iv) “Post Closing Determination Time” means the date and time immediately after the Expiration Date, (v) “Expiration Date” means the date and time denominated as such with respect to the Tender Offer (including extensions thereof) in the Schedule TO, (vi) “Voting Securities” means securities of the Company having the power generally to vote on the election of directors and other matters submitted to a vote of stockholders of the Company, and (vii) “affiliates” of the Principal Stockholder means any person or entity that directly, or indirectly through one of more intermediaries, controls, or is controlled by, or is under common control with, the Principal Stockholder.

(b) In calculating Excess Voting Power attributable to the Subject Shares: (i) there shall not be taken into account, and the term Subject Shares shall not be deemed to include, the voting power represented by any Class A Shares acquired by the Principal Stockholder after the Post Closing Determination Time (through his exercise of stock options, open market purchases or acquisition of shares in other post-Expiration Date transactions, other than share acquisitions derived, directly or indirectly, from Class A or Class B Shares owned by the Principal Stockholder at the Post Closing Determination Time), and (ii) there shall be taken into account the voting power represented by any Class A Shares issued to or acquired from third parties by the Company after the Post Closing Determination Time, including pursuant to the exercise of stock options, under employee benefit plans, in public or private transactions, in acquisition transactions, in open market purchases or similar circumstances, which net issuances and acquisitions will impact the calculation of the then applicable amount of the Excess Voting Power but not the Cap Amount. The provisions of Section 1.1(a) shall not apply to any Subject Shares which do not represent Excess Voting Power.

SECTION 1.2 Irrevocable Proxy. (a) As security for the Principal Stockholder’s obligations under Section 1.1, the Principal Stockholder hereby irrevocably constitutes and appoints the Company as his attorney and proxy in accordance with the Corporation Law, with full power of substitution and re-substitution, to cause his Subject Shares representing Excess Voting Power to be counted as present at any Company Stockholders’ Meeting (except to the extent otherwise provided in Section 1.1(a)(y) with respect to non-affiliated shares which are not counted as present), to vote his Subject Shares representing Excess Voting Power at any Company Stockholders’ Meeting, and to execute consents in respect of his Subject Shares representing Excess Voting Power as and to the extent provided in Section 1.1. The Principal Stockholder hereby revokes all other proxies and powers of attorney with respect to his Subject Shares representing Excess Voting Power that he may have heretofore

appointed or granted, and represents that any proxies heretofore given in respect of his Subject Shares representing Excess Voting Power, if any, are revocable.

(b) The Principal Stockholder hereby affirms that the irrevocable proxy set forth in this Section 1.2 is given in connection with the commencement by the Company of the Tender Offer, and that such irrevocable proxy is given to induce the Company to so commence the Tender Offer and to secure the performance of the duties of the Principal Stockholder under this Agreement. The Principal Stockholder hereby further affirms that the irrevocable proxy is coupled with an interest and, except as set forth in this Section 1.2 or in Section 5.1, is intended to be irrevocable in accordance with the provisions of Section 212 of the Delaware General Corporation Law. If for any reason the proxy granted herein is not irrevocable, then the Principal Stockholder agrees to vote his Subject Shares representing Excess Voting Power in accordance with Section 1.1 above. The parties agree that the foregoing is a voting agreement created under Section 218(c) of the Delaware General Corporation Law.

(c) This irrevocable proxy shall automatically terminate on the Termination Date (as hereinafter defined). Prior to that date, this irrevocable proxy shall not be terminated by any act of the Principal Stockholder or by operation of Law, whether by the death or incapacity of the Principal Stockholder or by the occurrence of any other event or events, it being understood that actions taken by the Company hereunder prior to the Termination Date shall be and remain valid as if such death, incapacity or other event or events had not occurred, regardless of whether or not the Company has received notice of the same.

SECTION 1.3 Acknowledgment. The Principal Stockholder hereby acknowledges that he has received and reviewed of a copy of the Schedule TO.
