                                                                    NEWS RELEASE

             GEAC COMPLETES TENDER OFFER FOR COMSHARE, INCORPORATED

       TRANSACTION BROADENS GEAC'S BUSINESS PERFORMANCE MANAGEMENT SUITE,
          DEMONSTRATES FURTHER COMMITMENT TO CORPORATE GROWTH STRATEGY

MARKHAM, ONTARIO AND ANN ARBOR, MICHIGAN-- August 1, 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, announced earlier today that Geac had acquired approximately 84% of
Comshare's outstanding shares, pursuant to a tender offer by Geac which expired
at midnight on July 31, 2003. As previously announced, Geac will provide a
subsequent offering period, expiring at 5:00 p.m. EDT on August 11, 2003, to
enable any Comshare shareholders who have not already done so to tender their
shares. Geac will acquire the balance of the shares not tendered through a cash
merger of its wholly owned subsidiary Conductor Acquisition Corp. with and into
Comshare.

The acquisition of Comshare further enhances Geac's Business Performance
Management offerings with the addition of Comshare's MPC(TM) suite of planning,
budgeting, forecasting, financial consolidation, and management reporting and
analysis solutions. The addition of Comshare demonstrates that Geac is executing
on its Business Performance Management strategy to offer a portfolio of
high-value solutions that optimize organizations' critical financial and
operations functions, and that help customers address regulatory and compliance
imperatives related to the Sarbanes-Oxley Act of 2002 and other similar
legislation. "Bringing Comshare into the Geac family is a win for Geac's and
Comshare's customers, shareholders and employees," said Charles S. Jones,
president of Geac. "This transaction not only responds to our customers' stated
need for powerful financial planning tools, it also stands to build shareholder
value by positioning Geac in another high-growth segment of the software
industry. We selected Comshare for its strength in the corporate performance
management market, its modern technology and its outstanding customer
satisfaction. We expect Geac to provide a platform for assisting Comshare to
grow while providing customers with more technology and product alternatives."

In a Research Alert published on June 23, 2003, AMR Research stated, "Comshare
is a fine fit for Geac... Comshare's existing product portfolio of financial
planning, budgeting, forecasting, and consolidation software will help Geac
position this broad range of [Business Performance Management] products with its
existing customers, supplementing its System21, SmartStream, and E- and M-Series
product lines."

Concurrent with Geac's acceptance of the tendered shares, James M. Travers has
been appointed President and Chief Executive Officer of Comshare, Inc. Travers
remains Senior Vice President of Geac Computer Corporation Limited, and
President of Geac Americas. To ensure seamless continuity of the business, Brian
Jarzynski, senior vice president, CFO and treasurer; Dave King, senior vice
president and CTO; Brian Hartlen, senior vice president, marketing; Kenneth
Kane, senior vice president, field operations; and



Patrick D. Berryman, vice president and general counsel of Comshare will remain
in their positions. Dennis Ganster resigned as President and Chief Executive
Officer of Comshare, Inc. to pursue other interests.

Mr. Jones said, "Comshare's management team, led by Dennis Ganster, has done an
excellent job of building an innovative product line and a loyal customer base.
I thank Dennis for his hard work, and his support of this transaction."

As contemplated by the merger agreement, six designees of Geac have been
appointed as directors of Comshare. The Geac designees, who will constitute a
majority of the Board of Directors of Comshare, are Anna C. Forgione, Steven
Horniak, Ruth Klein, Derek J. Murphy, Lou J. Pagotto and James M. Riley.
Comshare directors Richard Crandall, Kathryn A. Jehle and John H. MacKinnon,
along with Mr. Ganster, have resigned from the Board of Directors of Comshare.
Comshare directors Geoffrey Bloom, Alan G. Merten, John F. Rockart and Anthony
G. Stafford will continue in office pending completion of the merger, and will
constitute the committee of independent directors of Comshare contemplated by
the merger agreement.
