                     GEAC ANNOUNCES SUCCESSFUL CONCLUSION OF
                            TENDER OFFER FOR COMSHARE

                  -- GEAC OWNS APPROXIMATELY 90.6% OF COMSHARE --

MARKHAM, ONTARIO AND ANN ARBOR, MICHIGAN - August 13, 2003 - Geac Computer
Corporation Limited (TSX: GAC), a global enterprise software company for
Business Performance Management, and Comshare, Incorporated (Nasdaq: CSRE), a
leading provider of software that helps companies implement and execute
strategy, today announced the successful completion of the subsequent offering
period for Geac's tender offer to purchase all the outstanding shares of common
stock of Comshare at a price of US$4.60 per share. The subsequent offering
period expired at 5:00 p.m. EDT on Wednesday, August 13, 2003.

Based upon a tally by Equiserve Trust Company, N.A., the depositary for the
offer, an aggregate of 9,792,548 shares of Comshare common stock were validly
tendered in the initial offering period and subsequent offering period. Geac,
through its indirect wholly owned subsidiary Conductor Acquisition Corp., has
accepted for payment all shares validly tendered in the tender offer. In
addition, Conductor Acquisition Corp. has purchased directly from Comshare an
additional 363,201 common shares of Comshare at a price of US$4.60 per share,
for an aggregate price of US$1,670,725, in connection with the exercise of the
top-up option granted in the merger agreement between Geac and Comshare. The
top-up shares together with the shares tendered and accepted represent a total
of 10,155,749 shares, or 90.61% of Comshare's 11,208,347 total shares
outstanding.

Geac plans to effect a merger of Conductor Acquisition Corp. with and into
Comshare on Thursday, August 14, 2003, or as soon as practicable thereafter. The
merger will be consummated without a vote or meeting of Comshare stockholders,
in accordance with Michigan law. In the merger, each of the remaining shares of
Comshare common stock will be converted into the right to receive US$4.60 in
cash, without interest. In connection with the merger, all outstanding stock
options will be cancelled and each holder of an outstanding stock option to
purchase shares of Comshare's common stock at an exercise price less than
US$4.60 per share will, assuming such option has not been exercised prior to
completion of the merger, receive a cash payment equal to the difference between
the exercise price which otherwise would have been paid by such holder, and the
offer price of US$4.60 per share.

Questions and requests for assistance concerning the offer may be directed to
Georgeson Shareholder Securities Corporation, the dealer manager for the offer,
