                   COMSHARE ADOPTS SHAREHOLDER RIGHTS PLAN

Ann Arbor, MI, September 16, 1996 -- Comshare, Inc. (Nasdaq-NM: CSRE),
The Decision Support Company, today announced that its Board of Directors has
adopted a Shareholder Rights Plan ("Rights Plan"). 

"The Board of Directors has implemented the Rights Plan to protect the
interests of our shareholders and as an indication of our confidence in
the long-term strategic direction we've established for the Company," said T.
Wallace Wrathall, President and Chief Executive Officer.

"This confidence arises from a number of factors, including the solid foundation
provided by our focus on decision support applications for specific lines of
business and the new applications released in Fiscal 1996," he continued.  "We
have exciting product development plans for Fiscal 1997 aimed at adding new
applications, broadening our technology platforms, and further increasing market
appeal of all of our offerings." 

"The Rights Plan was not adopted in response to any specific effort to acquire
control of the Company, but rather is intended to assist shareholders in
realizing the long-term value of their investment in the Company," stated
Wrathall.  We join over 1,000 companies, including many software companies,
that have adopted shareholder rights plans with similar provisions to the plan
approved by our Board," continued Wrathall.

In connection with the adoption of the Rights Plan, the Board of Directors
declared a dividend of one right to purchase one one-hundredth (1/100th) of a
share of Series A Preferred Stock on each share of its outstanding Common
Stock. The initial exercise price of a right is $110 and the rights expire on
September 16, 2006. Distribution of these rights will be made to shareholders
of record on September 30, 1996.

The rights will become exercisable if a person or group acquires 15% or more of
the Company's Common Stock or announces a tender offer which would cause that
result. In addition, if a person or group acquires 15% or more of the Company's
Common Stock, the Rights will entitle shareholders (other than the acquiror) to
purchase the Company's Common Stock, or in certain cases, stock of the
acquiror, at a discount to market prices.

Details of the Rights Plan are outlined in a letter which will be mailed to all
shareholders.
