ITEM 5. OTHER EVENTS

         On June 22, 2003, Comshare, Incorporated entered into an Agreement and
Plan of Merger with Geac Computer Corporation Limited and its indirect wholly
owned merger subsidiary, Conductor Acquisition Corp., a Michigan corporation. A
copy of the agreement is attached as Exhibit 2.1. At the time of the execution
of the agreement, Codec Systems Limited, who owns approximately 14% of
Comshare's outstanding common stock, and Anthony Stafford, who is an officer and
majority shareholder of Codec and who is a Comshare director, entered into a
Tender and Voting Agreement with Geac, a copy of which is attached as Exhibit
2.2. Dennis G. Ganster, Comshare's Chairman, President and Chief Executive
Officer, also entered into a Tender and Voting Agreement, a copy of which is
attached as Exhibit 2.3.

         A copy of Comshare's press release, dated June 23, 2003, is attached as
Exhibit 99.1 and is incorporated herein by reference.

         This announcement is not a recommendation, an offer to purchase or a
solicitation of an offer to sell shares of Comshare. Geac has not commenced the
tender offer for shares of Comshare. Upon commencement of the tender offer for
shares of common stock of Comshare, which is expected to occur on or before July
3, 2003, Geac will file with the Securities and Exchange Commission a tender
offer statement on Schedule TO, and the Company will thereafter file with the
Commission a solicitation/recommendation statement on Schedule 14D-9. Comshare
stockholders are advised to read Geac's tender offer statement and Comshare's
solicitation/recommendation statement when they are available because they will
contain important information about Geac, Comshare, the tender offer and the
merger. Comshare stockholders may obtain free copies of these statements, when
available, from the Commission's website at www.sec.gov, or by contacting Geac
Investor Relations at 905.475.0525 x3325 or Comshare Investor Relations at
734.994.4800 or email bjarzynski@comshare.com.
