Fairfax, Virginia, September 6, 2004

A July 2004 Yankee Group report states that newly merged CGI-AMS now offers a "dynamic blend of consulting professionals and software expertise" in the telecommunications space, with special attention paid to Tapestry®, a modular solution for convergent rating, billing, and enterprise order management.

This report comes on the heels of CGI-AMS' July 7 release of Tapestry 5.2 and its expanded customer self-care and revenue assurance capabilities. Tapestry addresses the diverse needs of today's retail, wholesale, and government telecom service providers including VoIP and other IP-based services, allowing clients to achieve high customer satisfaction while managing costs and supporting new products and services.

"Tapestry is a proven asset to leverage. CGI has the opportunity to use Tapestry as a key point of expansion in the wireless and convergent communications market...," said Paul Hughes, Director of Billing and Payment Applications Strategies at the Yankee Group.

This industry analyst validation is good news for CGI-AMS, especially for its telecommunications practice which brings in more than a quarter of the company's total business. The Yankee Group also notes that CGI-AMS now has "scale and capability on par with leading systems integrators."

"The merger of CGI and AMS creates a powerful combination of systems integration, outsourcing, and software solutions for our Telecommunications customers," said Nazzic Turner senior vice president of CGI-AMS. "Tapestry is in the unique position of supporting the avalanche of IP services out-of-the-box. CGI-AMS will continue to expand on Tapestry's rating flexibility, positioning its usability for the myriad of products being offered by today's carriers."
