Transaction Highlights Pro Forma Guidance

FISCAL 2004 CDN$ CURRENT GUIDANCE PRO FORMA GUIDANCE(1) PRO FORMA RUN-RATE(2) Revenue $2.9 to $3.2 billion$3.3 to $3.6 billion $3.8 to $4.2 billion Growth Rate 8% to 17% 21% to 32% — Net Earnings $197 to $213million(3) $210 to $233 million $254 to $270 million Growth Rate 11% to 20%(3) 18% to 32% — Earnings per Share $0.49 to $0.53 $0.50 to $0.54(4) $0.58 to $0.61(4) Growth Rate 8% to 17% 11% to 20% — (1) The Pro Forma Guidance represents the Fiscal 2004 Current Guidance adjusted for the acquisition assuming closing on May 1st, 2004, and would incorporate five months of operations and certain anticipated operating efficiencies. (2) The Pro Forma Run-Rate and the expected 15% to 20% accretion to earnings are based upon the Fiscal 2004 Current Guidance plus annualized fiscal 2003 fourth quarter operations of AMS, excluding the U.S. DIG Business, and include twelve months of the full operating efficiencies expected to be realized. Full operating efficiencies may take more than twelve months to achieve. The Pro Forma Run-Rate is for illustrative purposes only. Fiscal 2003 fourth quarter earnings of AMS, exclusive of the U.S. DIG Business, are based on CGI management’s estimate of the allocation of overhead between the U.S. DIG business and other businesses of AMS. (3) Net earnings under the Current Guidance is derived from CGI’s Current Guidance for earnings per share and the number of shares outstanding as of December 31, 2003. (4) Earnings per share are after giving effect to US$250 million (CDN$331 million) of additional equity.

The assumptions used in the preparation of the Pro Forma Guidance and the Pro Forma Run-Rate, although considered reasonable by management at the time of preparation, may prove to be incorrect. The actual results for the period may vary from the above guidance and run-rate and such variation may be material.
