                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To the Plan Administrator
    of the Profit Sharing Plan
    of Comshare, Incorporated:



We have audited the accompanying statements of net assets available for benefits
of the PROFIT SHARING PLAN OF COMSHARE, INCORPORATED (the "Plan") as of June 30,
2000 and 1999, and the related statements of changes in net assets available for
benefits for the years ended June 30, 2000, 1999 and 1998. These financial
statements and the schedule referred to below are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
June 30, 2000 and 1999 and the changes in its net assets available for benefits
for the years ended June 30, 2000, 1999 and 1998 in conformity with accounting
principles generally accepted in the United States.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes is presented for purposes of additional analysis and is
not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedule has been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                               PROFIT SHARING PLAN

                            OF COMSHARE, INCORPORATED

                          NOTES TO FINANCIAL STATEMENTS


(1)   DESCRIPTION OF THE PLAN

      The information discussed below is a summary only and reference should be
      made to the Profit Sharing Plan of Comshare, Incorporated (the "Plan") or
      inquiries made of the Plan Administrator for more complete information.

      (a)     General

              The Plan is a defined contribution plan covering eligible
              employees of Comshare, Incorporated (the "Company"). The Plan
              provides retirement benefits and is subject to the provisions of
              the Employee Retirement Income Security Act of 1974 (ERISA). The
              Company administers the Plan and pays all plan administration
              costs, including fees paid to the Trustee. The operating expenses
              of the Investment Advisor are netted from the returns of the
              funds.

              The Employee Stock Ownership Plan (ESOP) of Comshare, Incorporated
              was merged with the Plan effective October 1, 1995. All of the
              assets of the ESOP which consisted primarily of Comshare common
              stock were transferred to the Plan and placed in the new Comshare
              Stock Fund.

      (b)     Trustee and Investment Advisor

              As of June 30, 2000 the Plan held all investments with Vanguard
              Fiduciary Trust Company (the "Trustee" and "Investment Advisor").

              In accordance with the Trust Agreement, the Trustee holds and
              administers the Plan's assets and executes transactions therewith
              for the purpose of providing benefits as described in the Plan
              agreement. The Investment Advisor executes all investment
              transactions.

      (c)     Management Estimates

              The preparation of financial statements in conformity with
              accounting principles generally accepted in the United States
              requires management to make estimates and assumptions that affect
              the reported amounts of assets and liabilities and disclosure of
              contingent assets and liabilities at the date of the financial
              statements and the reported amounts of income and expenses during
              the reporting period. Actual results could differ from those
              estimates.

      (d)     Contributions

              The Plan provides for annual employer fixed contributions equal to
              2% of eligible participants' compensation. In addition, the
              Company may make discretionary contributions, the amount of which
              is determined by the Board of Directors. There were no
              discretionary contributions in 2000, 1999, or 1998. To qualify for
              such employer contributions for any given Plan year, a participant
              must be credited with 1,000 or more hours of service during the
              Plan year and be employed by the Company on the last day of the
              Plan year.

              The annual employer fixed contribution for 2000 will be paid to
              the Plan by the Company in September, 2000 in the amount of
              $319,875 and is included in the employer's contribution
              receivables on the Statement of Net Assets Available for Benefits
              for the Year Ended June 30, 2000. Upon receipt of the employer
              fixed contribution, the Plan will allocate contributions to
              eligible participants based on the participants then current
              investment elections.

              All full-time employees and certain part-time employees are
              eligible to make employee before-tax contributions to the Plan at
              the beginning of the calendar quarter following the date of hire.
              Eligible participants begin sharing in employer contributions
              after completing one year of service. As of June 30, 2000 there
              were 305 active participants.

              Participants vest in employer discretionary contributions
              according to a five year schedule. Participants completing at
              least 1,000 hours of service in a given plan year are credited
              with an increase in vesting for such plan year. Full vesting also
              occurs upon retirement at age 65, or after death or total
              disability. Employer matching contributions vest according to a
              five year schedule (prior to 1/1/98 a seven year schedule was in
              effect) for participants with targeted compensation greater than
              the social security wage base. All other participants are fully
              vested in employer matching contributions.

              Employee contributions and employer fixed contributions are always
              fully vested.

      (g)     Loans and Hardship Withdrawals

              The Plan provides for hardship withdrawals in certain
              circumstances and for loans to participants. Loans are limited to
              50% of a participant's vested balance, and bear interest
              comparable to competitive bank rates for loans of similar purpose.
              Loans are repaid through payroll withholding, and typically mature
              within five years with a maximum maturity of twenty years. A 10%
              excise tax is imposed upon hardship withdrawals

                          NOTES TO FINANCIAL STATEMENTS

                                   (continued)


      (h)     Benefit Distributions

              Distribution of the vested amounts in a participant's account can
              be made upon termination of employment or upon retirement.
              Benefits are paid, at the option of the participant, in a lump sum
              payment or in periodic payments of substantially equal amounts for
              a specified number of years, not to exceed ten.

      (i)     Benefits Payable

              As of June 30, 2000 and 1999, the net assets available for
              benefits included $102,139 and $1,233,413, respectively, for
              benefits payable that were due but undistributed to participants
              as a result of termination of employment or retirement. These
              amounts are shown as liabilities on Form 5500 and are the only
              reconciling item between the financial statements and Form 5500.

      (j)     Allocation to Participants' Accounts

              The Trustee maintains the detailed accounts of the net assets
              available for benefits in the Plan. The Trustee values the fund
              for each investment option at market value on a daily basis. The
              net change in each fund's market value for the period is allocated
              to the accounts of participants within that fund in the same
              proportion that the balance of each participant's account bears to
              the total of the fund on the last day of the period. Interest
              income on loans to participants is credited directly to the
              individual participant's account. Company discretionary
              contributions and forfeitures are allocated to eligible
              participants' accounts in the same proportion that the
              participant's eligible compensation bears to the total eligible
              compensation of all participants for the year.

      (k)     Plan Termination

              Management of the Company has no intention to terminate the Plan.
              In the event the Plan is terminated, the participants will become
              fully vested and will receive the balances in their individual
              accounts.

      (l)     Federal Income Tax Status

              The Plan obtained its latest determination letter dated September
              16, 1996, in which the Internal Revenue Service stated that the
              Plan, as amended and restated effective July 1, 1994, was in
              compliance with the applicable requirements of the Internal
              Revenue Code (the "Code").

              The Plan has subsequently been amended and restated effective
              October 1, 1995 to reflect the merger with the ESOP. The Plan
              administrator is applying for a new determination letter. The Plan
              administrator and the Plan's tax counsel believe that the Plan is
              currently designed and being operated in compliance with the
              applicable requirements of the Code. Therefore, they believe that
              the Plan was qualified and the related trust was tax-exempt as of
              the financial statement date.

      (m)     Forfeitures

              Non-vested account balances of terminated employees are forfeited
              at the end of the quarter following the date of termination.
              Forfeitures were $11,242, $61,758 and $61,836 for the years ended
              June 30, 2000, 1999 and 1998, respectively. Forfeitures are
              allocated on a pro-rata basis to remaining participants.

(2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      (a)     Basis of Accounting

              The financial statements have been prepared on the accrual basis
              of accounting.

      (b)     Investments

              Investment transactions are recorded by the Trustee on a trade
              date basis. Investments are stated in the Statement of Net Assets
              Available for Benefits at market value. Realized gains and losses
              on sale of investments and unrealized appreciation of investments
              are computed based on the difference between the market value of
              the investments at the beginning of the year, or at the time of
              purchase if acquired during the year, and the market value of
              investments when sold or at Plan year-end.

      (c)     Compliance with SOP 99-3

              The Accounting Standards Executive Committee issued Statement of
              Position 99-3, "Accounting for and Reporting of Certain Defined
              Contribution Plan Investments and Other Disclosure Matters" (SOP
              99-3), which eliminates the requirement for a defined contribution
              plan to disclose participant-directed investment programs. As
              required by SOP 99-3, the Plan adopted SOP 99-3 for the 2000
              financial statements and reclassified certain amounts in the 1999
              and 1998 financial statements to eliminate the
              participant-directed fund investment program disclosures.


(3)   SUBSEQUENT EVENTS

              Effective July 7, 2000, three new investment funds were added to
              the Plan. The new fund options include the Vanguard Extended
              Market Index Fund, Vanguard Windsor II Fund and the R/S Emerging
              Growth Fund.

              As of September 8, 2000, the Company's stock was trading at $5.25
              per share compared to $4.75 per share at June 30, 2000. The
              investments in the Comshare Stock Fund consist primarily of the
              Company's stock which is valued in the accompanying Statement of
              Net Assets Available for Benefits at the June 30, 2000 share
              price.
