Calgary, Alberta, June 27, 2004

A consortium of major oil and gas companies have selected CGI Group Inc. (CGI) (TSX: GIB.A; NYSE: GIB) to build and maintain a sustainable production accounting solution. Devon Canada, EnCana, Husky Energy, Talisman Energy, and CGI have signed a co-venture contract whereby CGI will build, maintain and enhance a single solution to be used by these companies, over the next 10 to 20 years. This solution is intended to increase efficiency, improve the quality of information by providing end users more time for data analysis and ultimately result in the ability to make better business decisions. The new system is being developed as an industry solution that will be available to other oil and gas companies that operate in Canada.

"We are pleased to be part of this initiative to create an industry solution for production accounting. Changing production accounting systems is challenging and expensive. The prospect of having a sustainable long term solution is very appealing to us. The strong working relationship that has developed between the parties involved gives us confidence that the result will serve the industry well," said Bill Stevenson, comptroller upstream operations, EnCana Corporation.

Terry Johnson, senior vice-president, Western Canada, CGI added: "We are very excited about this partnership and the confidence these major companies have shown in our ability to deliver. This innovative solution adds to our service offerings and makes us a partner of choice given our breadth and depth of service and solution capabilities as well as our strong foothold in this constantly evolving sector. Moving forward, we expect other oil and gas companies to embrace and implement this leading edge solution."
