PRESS RELEASE FOR IMMEDIATE PUBLICATION

CGI extends tender offer for all of the outstanding shares of AMS

Montreal, Quebec — April 16, 2004 — CGI Group Inc. (TSX: GIB.A; NYSE: GIB) (“CGI”) today announced that its wholly-owned subsidiary, CGI Virginia Corporation (“CGI Virginia”), has extended its cash tender offer to purchase all of the outstanding shares of common stock of American Management Systems, Incorporated (Nasdaq: AMSY) (“AMS”) for $19.40 per share, net to the seller in cash and without interest. The offer, which previously was scheduled to expire at 12:00 Midnight, Eastern time, on Thursday, April 15, 2004, has been extended until 12:00 Midnight, Eastern time, on Thursday, April 29, 2004. The extension of the tender offer also extends the closing of the purchase of AMS’s defense and intelligence business by CACI International Inc. (“CACI”), pursuant to an asset purchase agreement in which CGI, AMS and CACI agreed to simultaneously close CACI’s asset purchase with the tender offer.

CGI has been advised by Computershare Trust Company of New York, the depositary for the tender offer, that as of the close of business on Thursday, April 15, 2004, approximately 36.6 million shares of AMS’s common stock, or approximately 85.7% of all of the outstanding shares of AMS’s common stock, had been validly tendered and not withdrawn pursuant to the offer.

Except for this extension, the terms and conditions of the offer remain in effect and unmodified.

CGI Virginia is extending the offer because all of the required authorizations that must be obtained pursuant to the offer (including the authorization from, or the expiration of the period of time for any applicable review process by, the Committee on Foreign Investment in the United States (“CFIUS”) under the Exon-Florio Amendment to Section 720 of the Defense Production Act of 1950 (the “Defense Production Act”)) were not obtained before the expiration of the offer period that was originally scheduled to expire at 12:00 Midnight, Eastern time, on Thursday, April 15, 2004. CGI, AMS and CACI are cooperating with CFIUS during its review of the transaction between the three companies under the Defense Production Act. The parties filed a joint Exon-Florio application with CFIUS on March 25, 2004. CGI believes that the proposed transaction will be found to raise no national security concerns. CGI Virginia expects to extend the offer for additional periods as necessary until all required authorizations that must be obtained pursuant to the offer are obtained.

As a consequence of the extension of the offer period, holders of shares of AMS’s common stock may tender or withdraw their shares until 12:00 Midnight, Eastern time, Thursday, April 29, 2004, unless the offer is further extended. If the offer is further extended, CGI will issue a press release no later than 9:00 a.m., Eastern time, Friday, April 30, 2004. Promptly after the expiration of the offer period, CGI

Virginia will accept for payment, and will pay for, all shares validly tendered in the offer and not withdrawn prior to such expiration.

AMS stockholders should read the solicitation/recommendation statement on Schedule 14D-9 of AMS and CGI’s Tender Offer statement on Schedule TO, including the Offer to Purchase, the Letter of Transmittal and the Notice of Guaranteed Delivery.
