Poznan, Poland, May 22, 2005

Bank Zachodni WBK, one of the largest retail banks in Poland, successfully implemented Strata™ Enterprise, the universal enterprise-wide rule-based decisioning and scoring platform from CGI Group Inc. (CGI) (TSX: GIB.SV.A; NYSE: GIB), the eight largest information technology (IT) services providers in the world. Installed in over 50 largest financial services and telecommunications institutions worldwide, Strata is a market leader in decisioning and scoring.

BZ WBK selected Strata only seven months ago, following a recommendation from AIB, a long-term client of CGI. After seamless integration with other systems in the bank and the transfer of business processes to this new solution, the system was officially launched in January 2005 to process first credit applications. Currently, Strata is operating in the capacity of an application scoring and decisioning engine in credit originations for cash loans and overdrafts. It will soon be used for credit cards and other areas. The entire implementation process was supported by CGI professionals.

The integration of Strata Enterprise as a decisioning and scoring engine at BZ WBK will result in significant benefits for the bank gained through the high degree of automation and increased operational efficiency. Functional richness of the system, its stability, flexibility, quick time-to-market, low TOC and independence of IT prompted BZ WBK to extend the use into additional areas of behavioral scoring, rating, and decisioning across the bank, including solutions imposed by regulatory requirements of Basel II.

Dariusz Gorzen, general manager for CGI in Poland said: “We are very pleased that BZ WBK has joined the group of satisfied clients and users of Strata. Our top end solution combined with high quality of services and expertise of our professionals has already resulted in a superior level of satisfaction and significant operational and financial benefits for BZ WBK.”
