Glass Lewis Recommends Shareholders Vote ''FOR'' Geac's Slate of Directors; Ontario Teachers' Pension Plan Also Supports Geac Board Nominees.

MARKHAM, Ontario and SOUTHBOROUGH, Mass. -- Geac Computer Corporation Limited (TSX: GAC and NASDAQ: GEAC) today announced that Glass Lewis & Co., a leading independent proxy advisory firm, has recommended that its clients vote to elect Geac's slate of nominees to the Company's Board of Directors. In addition, a significant Geac shareholder, the Ontario Teachers' Pension Plan ("OTPP"), an independent corporation with net assets of approximately $88 billion that is responsible for investing the fund's assets and administering the pensions of Ontario's 158,000 elementary and secondary school teachers and 101,000 retired teachers, has said publicly that it will vote for all of Geac's Board nominees.

Geac's Board nominees last week received the recommendation of Institutional Shareholder Services Canada ("ISS Canada"). All of Geac's eight current directors are standing for reelection at the Company's annual meeting on September 13, 2005.

Glass Lewis stated in its report, "We believe the Company has demonstrated its ability to create real value for shareholders, particularly since the management change in August 2003. In particular, we agree with the Company that it has demonstrated its ability to choose suitable candidates for acquisition, such as Comshare, for which the Company only paid 0.66 times revenue. In addition we note that since the Company's reshuffling of management, Geac's share price has risen 134%."

The Glass Lewis report continues, "We do not believe the dissident nominees have demonstrated sufficient cause for removing the incumbent directors. While we understand that Crescendo has some apprehension regarding the sudden availability of a large amount of cash and credit, we believe the board has demonstrated its ability to effectively pursue strategic and accretive business opportunities. It is, in fact, the Company's commendable performance over the past two years that has generated a good chunk of the available capital. Furthermore, we find the withdrawal of Crescendo's previous nominee, Gerry Smith, to be somewhat troubling. The abrupt change of nominees calls into question whether a suitably rigorous process was utilized by Crescendo to identify appropriate candidates. Accordingly, we recommend that shareholders vote FOR all management nominees, and NOT VOTE the dissident "gold" card. "

C. Kent Jespersen, Non-Executive Chairman of Geac, said, "This endorsement from Glass Lewis comes on the heels of a similar endorsement that we received last week from ISS Canada. The fact that both Glass Lewis and ISS Canada have recommended our nominees, and that Ontario Teachers' Pension Plan is voting for our full slate, are resounding acknowledgments that this Company and its Board are working in the best interests of shareholders."

Crescendo has targeted two of the current Geac Board members, Michael D. Marvin and Robert L. Sillcox, to be replaced by dissident nominees. The Board believes these two directors have extensive, highly relevant experience and have made invaluable contributions to Geac. Geac's current Board members collectively have extensive industry and corporate governance experience and are dedicated to supporting Geac's success through responsible and well-considered strategic actions that create and return value to all shareholders.

Geac encourages shareholders to vote to reelect Geac's slate of eight directors. Shareholders can vote by phone, internet or mail, and instructions can be found on the white proxy form. If shareholders have questions about voting, they can contact Geac's proxy solicitor, Georgeson Shareholder Communications, toll-free at [phone].
