Fairfax, VA, August 15, 2006

CGI Federal, Inc., a wholly-owned U.S. operating subsidiary of CGI Group Inc., (NYSE: GIB; TSX: GIB.A) today announced that USAID has completed the worldwide implementation of CGI's Momentum® financial management system (referred to as Phoenix by USAID).

"The successful implementation of Momentum to USAID Headquarters in Washington, D.C., and to more than 50 worldwide missions is the culmination of a project that included consideration of over one hundred currencies, diverse languages and cultural practices, round-the-clock operations in multiple time zones, and diverse network and telecommunication infrastructure environments of developing nations," said CGI Vice President Donna Ryan. CGI provided on-site training and implementation support at each mission as well as full-time solution center staffing in Cairo, Egypt; Manila, Philippines; Accra, Ghana; and Nairobi, Kenya.

With Phoenix now fully deployed, USAID's entire financial and accounting operation runs on a single, corporate system providing full auditability, real-time, online access to, and reporting of, financial information on a global basis. Phoenix also offers USAID the flexibility to consolidate its mission-based financial staff and activities into centralized locations, creating the opportunity to target staff and quickly pull out from any location that becomes dangerous or unstable, while still supporting projects underway in that location. "As the key partner in our financial modernization effort which began in 1999, the CGI team and Momentum solution have been instrumental in helping us achieve our vision of having a single, agency-wide financial management system," said Lisa Fiely, Chief Financial Officer, USAID.
