         agreement of Codec. To Codec's knowledge, no "affiliate" or

         enter into and perform its obligations under this Agreement, and the
         execution, delivery and performance of this Agreement by Codec has been
         duly authorized by all necessary corporate proceedings. This Agreement
         constitutes a valid and binding obligation of Codec and the performance
         of its terms does not constitute a violation of Codec's charter

         decree or contract to which Code is a party.

                  b. There are no arrangements, agreements or understandings
         between Codec and Comshare other than as set forth in this Agreement.

                  c. There are no arrangements, agreements or understandings
         between Codec and any other person regarding Comshare or its common
         stock, other than those relating to Codec's distributorship

         2. Representations and Warranties of Comshare. Comshare hereby
represents and warrants to Codec as of the date hereof as follows:

                  a. Comshare has full power and authority to enter into and
         perform its obligations under this Agreement, and the execution,
         delivery and performance of this Agreement by Comshare has been duly
         authorized by the Board of Directors of Comshare and requires no
         further Board of Directors or stockholder action. The Board of







         Directors of Comshare may be referred to hereinafter as the "Board."
         This Agreement constitutes a valid and binding obligation of Comshare
         and the performance of its terms does not constitute a violation of its
         articles of incorporation or by-laws or a default under any instrument,
         judgment, order, writ, decree or contract to which Comshare is a party.

                  b. There are no arrangements, agreements or understandings
         between Codec and Comshare other than as set forth in this Agreement,
         other than those relating to Codec's distributorship relationship with

         3. Representations and Warranties of Stafford. Stafford hereby
represents and warrants to Comshare as of the date hereof as follows:

                  a. Stafford is not the subject of any order, judgment, writ or
         decree which prohibits him from serving as an officer or director of
         Comshare or any company that has a class of securities registered
         pursuant to Section 12 of the Exchange Act. Except as set forth in
         Section 1(a) above, neither Stafford, nor, to his knowledge, any
         affiliate, associate or immediate family (as defined in Item 404(a) of
         Regulation S-K promulgated by the Securities and Exchange Commission
         ("SEC")) of Stafford, other than Codec, beneficially owns any shares or
         rights to acquire shares of Comshare common stock.

                  b. No event has occurred with respect to Stafford that would
         require disclosure in a Comshare report or other document filed on the
         date hereof pursuant to the Securities Act of 1933, as amended (the
         "Securities Act"), or the Exchange Act, pursuant to Item 401(f) or Item
         404 of Regulation S-K other than those relating to Codec's
         distributorship relationship with Comshare.

         4. Directorships. Comshare agrees that upon the execution of the
Agreement, the Comshare Board will elect Stafford to the Board, and will
recommend that shareholders vote for the election of Stafford to the Board of
Directors at Comshare's 2002 and 2003 Annual Meetings of Shareholders. In
addition, the Board will elect one additional person, determined as set forth
below, (the "Independent Director") to the Board, and will recommend that
shareholders vote for the election of the Independent Director to the Board at
Comshare's 2002 and 2003 Annual Meetings of Shareholders, subject to a separate
agreement between Comshare, Codec and the Independent Director in which the
Independent Director makes representations as to himself similar in form to
those set forth in Section 3 and agrees to be bound by this Agreement to the
same extent as Stafford.

                  a. Comshare and its Board agree to nominate and support
         Stafford and the Independent Director for re-election to the Board of
         Comshare, as long as this Agreement is in effect and has not been
         terminated.

                  b. Stafford and the Independent Director will be entitled to
         receive the identical compensation and benefits being paid to the other
         non-employee directors of Comshare, including the reimbursement of
         out-of-pocket expenses incurred in attending Board and committee
         meetings in accordance with Company policies regarding the same.


                                       2






                  c. Codec shall not provide, and Stafford and the Independent
         Director shall not accept, any incentive or compensation that would
         influence them to recommend or support any significant initiative
         affecting Comshare and its stockholders.

                  d. The procedure for the selection of the Independent Director
         shall be as follows: Codec will propose an individual who is qualified
         to serve pursuant to the standards set forth in Section 3(a) above and
         who is not an officer, director, former officer or director, affiliate
         or associate of Codec or Comshare. If the Board determines that
         individual proposed by Codec is acceptable to the Board, then such
         individual shall be elected to the Board as the Independent Director.
         If the Board reasonably determines that the individual proposed by
         Codec is not acceptable (the reason for which may include, but are not
         limited to, his failure to satisfy the qualifications set forth in the
         first sentence of this Section 4(d)), then Codec shall propose
         additional candidates to the Board until an acceptable Independent
         Director candidate is approved by the Board. The Board will not
         unreasonably withhold its acceptance of an individual proposed by
         Codec. If the Independent Director resigns from the Board, or if he
         dies or becomes disabled, Comshare and Codec shall replace the
         Independent Director with a qualified individual to serve the remainder
         of the Independent Director's term or terms pursuant to paragraph 4(a)
         of this Agreement, using the procedures set forth above in this
         subsection (d) for the initial election of an Independent Director,
         (the "Replacement Director"). The Replacement Director will have all of
         the rights, benefits and obligations of this Agreement. As a condition
         to the Replacement Director being appointed to the Board, he shall
         agree to make representations as to himself similar in form to those
         set forth in Section 3 and agree to be bound by this Agreement to the
         same extent as the Independent Director. References to the Independent
         Director in this Agreement shall refer to the Replacement Director once
         he is elected as a member of the Board.

                  e. Stafford shall serve on the Nominating Committee and the
         Independent Director shall serve on the Compensation Committee, if
         eligible to do so under applicable rules of the SEC and The Nasdaq
         Stock Market. At the first meeting of the Board following the 2002
         Annual Meeting of Shareholders, the Board will appoint Stafford as
         Chairman of the Nominating Committee.

                  f. During the term of the Agreement, beginning immediately
         after the 2002 Annual Meeting of Shareholders, the number of Board
         members shall not exceed eight members, provided that the Board may
         increase the maximum number of Board members by one to accommodate an
         additional member to serve on the Audit Committee who constitutes an
         independent financial expert (as those terms are defined by the SEC and
         the Nasdaq Stock Market) in order to satisfy SEC and The Nasdaq Stock
         Market requirements, including avoiding disclosure that the Audit
         Committee does not have a financial expert as a member.

         5. Codec's Prohibited Conduct. During the term of this Agreement,
Codec, Stafford and the Independent Director shall not, and Codec shall use its
reasonable best efforts to cause its officers, directors, managing personnel,
affiliates and associates to not, and Stafford and the Independent Director
shall use their respective reasonable best efforts to cause their immediate
family to not, directly or indirectly, without the prior written consent of
Comshare:

selected by each party or, in the event such firms are unable to agree, a third
nationally recognized investment banking firm to be selected by them) of such
other property included in such price. For this purpose:

within such three (3) day period, the parties shall promptly select a third firm
whose determination shall be made within an additional three-(3) day period and
shall be conclusive.

                           (ii) The parties shall use their best efforts to
cause any determination of the value of property other than securities to be
made within seven (7) business days after Comshare's receipt of all information

within an additional three (3) day period and shall be conclusive.

                           (iii) The date on which Comshare must exercise its
right of first refusal shall be extended until three (3) business days after the
determination of the value of property included in the purchase price.

the closing of the purchase of the Disclosed Shares with respect to which such
right has been exercised shall take place within twenty (20) calendar days (or
if approval of such purchase by Comshare's stockholders is required by law or
pursuant to any regulatory rule or policy, within sixty (60) calendar days)
after Comshare gives notice of such exercise.

                  d. If Comshare does not exercise its right of first refusal
hereunder within the time specified for such exercise, Codec or Stafford, as the
case may be, shall be free during the period of ninety (90) calendar days

of shares of Comshare common stock they, and their officers, directors, managing
personnel, affiliates, associates and immediate family, beneficially own.

         10. Termination. This Agreement shall terminate and Stafford and the
Independent Director shall immediately tender their respective resignations from
the Board if requested by the Board as a result of a majority vote, other than
the vote of Stafford and the Independent Director, upon the earlier of: (i)
Codec having beneficial ownership of less than five percent (5%) of the
outstanding shares of common stock of Comshare; (ii) any person becoming the
beneficial owner of more than 50% of Comshare's voting stock, including by way
of merger, acquisition or other type of business combination, (iii) the
dissolution or merger of Codec or any other transaction which results in the
failure of Codec to exist as a separate legal entity; provided that this
Agreement shall be binding on the party who receives the Disclosed Shares as a
result of such dissolution, merger or other transaction and it shall be a
condition of such dissolution, merger or other transaction that such person
agree to be bound by this Agreement to the same extent as Codec, (iv) in the
event of a material breach of this Agreement by Comshare or Codec, in the
discretion of the non-breaching party, or (v) the written consent of Comshare
and Codec. If this

                                       7






Agreement has not been previously terminated as provided in the prior sentence,
this Agreement shall terminate on the day following Comshare's 2003 Annual

Independent Director acknowledge that they will be subject to Comshare's insider
trading and disclosure policies, as in effect from time to time, at any time
while they are on the Board to the same extent as the other directors of
Comshare. Codec, Stafford and the Independent Director expressly agree to
maintain material nonpublic information concerning Comshare in confidence, which
agreement shall be covered by Section 243.100(b)(2)(ii) of Regulation FD in
instances where SEC Regulation FD applies. This Section 12 shall survive any
termination of this Agreement.

         13. Remedies. Comshare, Codec, Stafford and the Independent Director
acknowledge and agree that a breach or threatened breach by either party may
give rise to irreparable injury inadequately compensable in damages, and
accordingly each party shall be entitled to injunctive relief to prevent a
breach of the provisions hereof and to enforce specifically the terms and
provisions hereof in any state or federal court having jurisdiction, in addition
to any other remedy to which such aggrieved party may be entitled to at law or
