Geac Opposes Director Nominees by Dissident Hedge Fund.

MARKHAM, Ontario and SOUTHBOROUGH, Mass. -- Geac Computer Corporation Limited (TSX: GAC and NASDAQ: GEAC), a global enterprise software company, today said the Geac Board of Directors unanimously opposes the election of two dissident director nominees proposed last Friday by Crescendo Investments II, LLC, because it believes their election would not be in the best interest of other Geac shareholders. Crescendo Partners, headed by Eric Rosenfeld, is a New York activist hedge fund that has been accumulating shares in Geac since early March, disclosed a 5% ownership position in the company on Friday, August 12, and last week commenced a proxy contest.

Geac's 2005 annual meeting of shareholders is scheduled for Tuesday, September 13, 2005. Shareholders of record as of July 15, 2005, are eligible to vote for directors at the meeting.

C. Kent Jespersen, Non-Executive Chairman of Geac, said on behalf of the Board, "Crescendo first approached Geac and demanded two Board seats only two weeks ago. This past Thursday, I and two other independent Geac directors met with Eric Rosenfeld at his request on one day's notice. He again demanded Board seats for himself and Gerry Smith, whom no director has ever met, and when the Board did not immediately agree, Crescendo filed proxy materials the next day. Caving in to Mr. Rosenfeld's ultimatum would have violated our Corporate Governance and Nominating Committee processes for evaluating potential director nominees. These processes include conducting sufficient diligence regarding changes to Board composition and specific director candidates to enable the Board to make informed decisions."

Jespersen continued, "Geac shareholders have been well served by the Company's current leadership and business strategy. Since the new management team was installed by the Board approximately two years ago, Geac's financial performance has improved dramatically and the share price has more than doubled, far exceeding all relevant indices. Geac's Board of independent and highly experienced directors is working to generate further increases in shareholder value, and the Board of Directors has been engaged in acquisition and strategic reviews advised by Bear, Stearns & Co. since the end of 2004.

During the past two years under Geac's new leadership team, Geac's share price has appreciated by 124% to C$11.83 last Friday from C$5.29 on July 17, 2003. By comparison, the NASDAQ and the TSX Composite Index increased only 26% and 49%, respectively, over the same period. During the last two fiscal years since Charles Jones was named Chief Executive Officer, net earnings have increased 141%, to US$77.0 million, or US$0.87 per diluted share, for the year ended April 30, 2005, up from US$31.9 million, or US$0.39 per diluted share, for the year ended April 30, 2003. During the same two-year period, EBITDA margin increased to 22.5% from 16.1%, and cash and short-term investments more than doubled to $188.2 million from $89.8 million.

Geac urges shareholders to reelect the Company's eight Board nominees by completing and returning the white proxy card. For assistance in voting, shareholders can call Geac's proxy solicitors, Georgeson Shareholder Communications, toll-free at 1-866-765-7561.

Further details are provided in Geac's 2005 management proxy circular and Annual Report, including audited financial statements, which are available in the Investor's section of the company's website.
