Montreal, Quebec, September 9, 1999

CGI today announced an enterprise alliance with Microsoft Corporation, which will enable CGI to develop and deploy leading edge solutions for the telecommunications, government and financial services markets across the United States and Canada. Under the three-year agreement, CGI will deliver best-of-breed, reliable solutions founded on the Microsoft® enterprise platform in order to meet the changing needs of its clients. Based on the market potential of this agreement, CGI is targeting revenue growth of US$500 million over this three-year period

"CGI is pleased to have signed this agreement with Microsoft, a world-class provider of software solutions," said Jean Brassard, CGI's President and COO. "After investing heavily in Year 2000 compliance, companies across North America are preparing to launch new IT solutions that leverage emerging technologies including eCommerce and web-based applications. Teaming with Microsoft will allow CGI to maintain its leadership in Canada in these emerging technologies, while significantly enhancing its access to large U.S. clients. Combining CGI's strong systems integration, consulting and outsourcing expertise with Microsoft's well established technology solutions provides for a powerful service offering."

Under the alliance, Microsoft will provide CGI with software, development and support services. And, CGI will invest in the training of at least 500 new Microsoft Certified Engineers (MCSE's), Developers (MCSD's) and Database Administrator's (MCDBA's) to design, develop and implement business solutions. Additionally, Microsoft will provide Microsoft Consulting Services personnel to CGI for assistance in knowledge transfer, practice development and customer project support.

The agreement, which is non-exclusive for both companies, will further enhance CGI's ability to serve the needs of clients that have selected the Microsoft platform as their technology of choice. The agreement addresses the tremendous growth Microsoft is experiencing in the enterprise space and the requirement for partners who can deliver rich enterprise solutions to their customers.

"It's exciting for us to have CGI as an Enterprise Partner, and to have our products being complemented by their strong systems integration, consulting and outsourcing expertise," said Simon Witts, General Manager of Microsoft Canada. "We rely on strong partnerships to help us provide our enterprise customers fully integrated, end-to-end information technology solutions to help them improve their businesses. CGI brings with it strong market knowledge, industry expertise and sales force capacity to help us better understand the business needs in key market sectors such as insurance, banking, telecommunications and government."

"This is an important alliance because it provides a great opportunity for us to reach out to our enterprise customers with CGI's business solutions expertise in consulting and systems integration and outsourcing services," said Orlando Ayala, Senior Vice President of Microsoft Americas and South Pacific region. "This North American alliance will focus on the emerging industries of telecommunications and financial services and we are working with CGI to provide customers in these industries with leading-edge solutions."
