                       AMENDMENT NO. 1 TO RIGHTS AGREEMENT

     This Amendment No. 1 (this "Amendment"), dated as of April 25, 2007, is by
and between COVANSYS CORPORATION, a Michigan corporation (the "Company"), and
COMPUTERSHARE TRUST COMPANY, N.A. (formerly known as EquiServe Trust Company,
N.A). (the "Rights Agent").

     WHEREAS, the Company and the Rights Agent entered into that certain Rights
Agreement, dated as of December 1, 2004 (the "Rights Agreement");

     WHEREAS, capitalized terms used but not otherwise defined in this Amendment
shall have the meaning given them in the Rights Agreement;

     WHEREAS, the board of directors (the "Board") of the Company has been
presented with a proposal whereby pursuant to an Agreement and Plan of Merger
(the "Merger Agreement") by and among the Company, Computer Sciences
Corporation, a Nevada corporation ("CSC"), and Surfside Acquisition Corp., a
Michigan corporation wholly owned by Parent ("Merger Sub") (CSC and Merger Sub,
together with their permitted successors and assigns, are collectively referred
to herein as the "Other Parties") at a meeting of the board of directors of the
Company held on April 25, 2007 (the "Meeting"), pursuant to which Merger Sub
will be merged with and into the Company (the "Merger");

     WHEREAS, upon the effectiveness of the Merger, the Other Parties
collectively will acquire 100% of the outstanding shares of the Common Shares;

     WHEREAS, the acquisition of 100% of the outstanding shares of the Common
Shares would result in the acquiring entity or entities being deemed to be an
"Acquiring Person" under the Rights Agreement, which would trigger certain
events pursuant to the terms of the Rights Agreement;

     WHEREAS, at the Meeting the Board determined that it is in the best
interest of the Company and its Shareholders to amend the Rights Agreement prior
to the Company entering into the Merger Agreement so that (i) the Other Parties
will not thereby become Acquiring Persons under the Rights Agreement, (ii)
neither a Distribution Date nor a Stock Acquisition Date will thereby occur, and
(iii) the Expiration Date will be immediately prior to the Effective Time, as
defined in the Merger Agreement;

     WHEREAS, pursuant to Section 27 of the Rights Agreement, this Amendment is
being executed by the Company and the Rights Agent for the purpose of amending
the Rights Agreement as set forth below.

     NOW THEREFORE, in consideration of the mutual covenants and conditions
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

          the Merger Agreement or compliance with the terms of the Merger
          Agreement, including proxies or agreements to vote Common Shares
