Los Angeles, California, May 24, 2005

CGI-AMS Inc., the wholly-owned U.S. operating subsidiary of CGI Group Inc. (CGI) (TSX: GIB.SV.A; NYSE: GIB), announced today that Los Angeles County has extended its relationship with CGI-AMS via a multi-year, US$33 million contract. This supplements a previous agreement, which included the implementation of the County's core financial system. Los Angeles County has been a CGI-AMS client since 1986 and is the largest County in the United States.

"The County's top priority is to provide top-notch services, delivered with speed and efficiency to our citizens, while maximizing taxpayer dollars," said J. Tyler McCauley, Auditor-Controller for Los Angeles County. "We selected AMS Advantage 3 as the most cost-efficient and best solution for us."

AMS Advantage Financial Management will provide County officials with Web-based and real-time access to reliable financial information, enabling more timely decisions on funding for programs across the full range of services offered to County residents. The new system will streamline business processes supporting the management of the County's $17 billion budget, eliminate redundant investments, and allow the County to retire dozens of disparate systems.

In addition to providing the County with AMS Advantage Financial Management, CGI-AMS will assist with examining the County's requirements in the human resources arena to include HR administration, time and attendance, benefit administration, payroll, recruitment, employee self-service, and other related areas.

"Our collaboration with CGI-AMS has been extremely beneficial. We have pinpointed numerous efficiencies during the analysis phase of the engagement, and anticipate continued success on many levels," said McCauley.

Donna Morea, president of CGI-AMS added: "CGI-AMS is partnering with Los Angeles County to implement truly transformational systems that will ultimately provide residents and employees with improved services in a timely and cost-effective manner. Equally important, the County is empowered to centrally monitor organizational performance and leverage that information to further improve operations while reducing costs. It is yet another example of why organizations turn to CGI-AMS to provide outstanding services for measurable results. This really speaks to what all levels of government are trying to do today."

With government best practices embedded in the solutions, the AMS Advantage suite is tailored to meet the unique administrative needs of state and local public sector entities.

AMS Advantage is used by more than 190 public sector clients, 45 of which have already committed to implementing the new Web-based AMS Advantage 3 solution. The company incorporates more than 30 years of government experience and knowledge in the public sector market. AMS Advantage is a flexible, module-based solution that automates document workflow, decreases paperwork and ultimately improves customer service and facilitates decision-making.
