Montreal, Quebec, December 16, 2002

CGI Group Inc. (CGI) (TSX: GIB.A; NYSE: GIB) today announced that it has completed the acquisition of ProjExpert, a Montreal-based consulting company specializing in the implementation of Enterprise Resource Planning (ERP) specific to Oracle applications. ProjExpert created a niche for itself in the integration of financial systems within the sectors of government, financial services and manufacturing. With this acquisition, sixteen professionals will join CGI's existing Oracle team located in Montreal.

ProjExpert, with revenues of CDN$2.75 million, was founded in 1996. Founder and principal associate of ProjExpert, Pierre Cloutier comments: "Having collaborated with CGI in the past, we felt very positive about our shared culture and values in reference to our vision and way of doing business. To expand our operations, we needed a solid partner who was committed to growing and evolving their ERP practice. CGI was a logical choice."

Pierre Turcotte, senior vice-president, Greater Montreal for CGI added: "The demand for ERP expertise, particularly in the public, manufacturing and distribution sectors, is growing rapidly. Their combined business and technological experience is very impressive and will help us continue to build our practice. Together, we will have an increased ability to penetrate this growing market."

Over the years, CGI has developed an extensive ERP practice North America-wide by building a team of professionals knowledgeable in various software packages. ERP software is geared at streamlining business processes such as finance, human resources, planning and sales. The result is creating an enhanced competitive edge.
