                                                                    NEWS RELEASE

GEAC COMPLETES ACQUISITION OF COMSHARE

MARKHAM, ONTARIO - August 15, 2003 - Geac Computer Corporation Limited (TSX:
GAC), a global enterprise software company for Business Performance Management,
today announced the completion of its acquisition of Comshare, Incorporated
(Nasdaq: CSRE). The acquisition was completed on August 14, 2003 by the merger
of Conductor Acquisition Corp., an indirect wholly owned subsidiary of Geac,
with and into Comshare in a "short form" merger in accordance with Michigan law.
As a result of the merger, Comshare is now an indirect wholly owned subsidiary
of Geac.

The merger follows a cash tender offer for all outstanding shares of Comshare at
a price of US$4.60 per share, which was completed upon the expiration of a
subsequent offering period on August 13, 2003. As a result of the merger, each
outstanding share of Comshare not owned by Geac or Conductor has been
automatically converted into the right to receive US$4.60 per share in cash,
without interest. Former Comshare shareholders who did not tender their shares
in the tender offer will receive a Letter of Transmittal that will instruct them
as to how to receive the US$4.60 per share payment.

"We're pleased this merger has gone so smoothly," said Charles S. Jones,
president and chief executive officer of Geac. "Clearly it is an opportunity to
build shareholder value by positioning Geac in a potentially growth segment of
the software industry. Planning, budgeting, forecasting and financial
consolidation are key components of our overall Business Performance Management
strategy. The successful completion of this conservatively priced acquisition
marks another tangible milestone in Geac's growth strategy, but, more
importantly, it extends our suite of high-performance applications creating
significant value for our customers around the world."

"Regulatory and compliance imperatives related to the Sarbanes-Oxley Act of 2002
and current and proposed Canadian securities laws require that CEOs and CFOs
have greater visibility into their financial performance processes through
effective planning, budgeting and forecasting of business metrics. These
regulatory initiatives should be a key driver for growth for Geac through a
combination of new license revenue and extended service and support contracts,"
said Timothy J. Wright, chief technology officer and chief information officer
of Geac. "Businesses today demand auditable and accountable control over their
core processes, including systems of



internal control. We are focused on delivering that control to our global
customers through solutions like our Geac Comshare MPC and Geac Extensity
Expense Reports product suites. These high-value products for the first time
provide the necessary visibility into financial operations, allowing CEOs and
CFOs to be confident that their companies are meeting compliance mandates while
increasing their overall business performance."

Geac acquired control of Comshare for accounting purposes on August 6, 2003 and
will consolidate the results of Comshare into its results from that date
forward.
