Montreal, Quebec, March 18, 2004

CGI Group Inc. (CGI) (TSX: GIB.A; NYSE: GIB) announced today the completion of its previously announced (i) firm underwritten private placement in Canada and the United States of approximately 33.1 million subscription receipts at a price of CDN$8.00 per subscription receipt for gross proceeds of approximately CDN$264.6 million and (ii) private placement of approximately 8.3 million subscription receipts with BCE Inc. at a price of CDN$8.00 per subscription receipt for proceeds of approximately CDN$66.1 million, on the same terms and conditions as the firm underwritten private placement offering. The private placements were undertaken in connection with CGI's previously announced acquisition of American Management Systems, Inc. (Nasdaq: AMSY) (AMS) by way of tender offer.

The firm underwritten private placement offering was co-underwritten by National Bank Financial Inc. and Credit Suisse First Boston Canada Inc.

Each subscription receipt will be automatically exchanged for one Class A Subordinate share of CGI, without payment of additional consideration, on the date that CGI accepts for payment at least a majority of the outstanding shares of AMS under the tender offer.

The gross proceeds from the private placements will be held in escrow pending the completion of the tender offer, which is anticipated to occur in May 2004, but no later than July 1, 2004.

This press release is not an offer in the United States of the subscription receipts or the Class A subordinate shares into which the subscription receipts are exchangeable. Neither the subscription receipts nor such Class A Subordinate shares have been or will be registered under the Securities Act of 1933, as amended, and neither may be offered or sold in the United States absent registration or an applicable exemption from registration requirements thereunder.
