                                    PREAMBLES


         SECTION 1.01 ESTABLISHMENT OF PLAN. Effective June 1, 1986, Comshare,
Incorporated (the "Company") adopted the Benefit Adjustment Plan of Comshare,
Incorporated to provide designated Employees with a program of deferred
compensation. The plan has been amended from time to time and is hereby amended
and restated effective November 6, 1997 (the "Plan").

         SECTION 1.02 PURPOSE. The Company desires to retain certain of its
Employees by designating them as Participants in a program which will (i)
provide them with the opportunity to defer a portion of the Compensation which
otherwise would be paid to them currently ("Deferred Compensation"); (ii)
provide for the payment of benefits which otherwise would be currently funded by
the Company under its Tax-Qualified Retirement Plans but for the limitations of
Section 415 of the Internal Revenue Code of 1986, as amended ("Code") ("Excess
Benefits"); and (iii) provide for the payment of benefits which otherwise would
be currently funded by the Company under its Tax-Qualified Retirement Plans but
for the restrictions of Sections 401(a)(17), 401(k) and 401(m) of the Code
("Restricted Benefits"). Prior to August 14, 1997 the Company also (a) provided
benefits based on a Social Security integration formula ("Social Security
Integration Benefits"); and (b) provided discretionary supplemental compensation
benefits based on set percentages of a Participant's Compensation in excess of
$100,000, as indexed from time to time in accordance with Section 6.02
("Supplemental Compensation"). Participants with vested Social Security
Integration Benefits and Supplemental Compensation Benefits on August 14, 1997
shall continue to retain vested rights to such amounts after August 14, 1997.

         SECTION 1.03 INTERPRETATION AND GOVERNING LAW. This Plan is intended to
constitute an unfunded program maintained primarily for the purpose of providing
deferred compensation for a select group of management or highly compensated
employees consistent with the requirements of Sections 201(2), 301(a)(3) and
401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"). In part, the Plan is also intended to constitute an "excess benefit
plan" as defined in ERISA Section 3(36).

                          DEFERRED COMPENSATION ACCOUNT

         SECTION 4.01 ELIGIBILITY. An Employee who is an officer of the Company
may participate in the Deferred Compensation Account portion of the Plan.

         SECTION 4.02 ELECTIVE COMPENSATION DEFERRAL. Each Participant shall be
permitted to elect annually in writing, prior to the beginning of any calendar
year, to have a designated whole percentage of his or her Compensation to be
earned during the year credited to his or her Deferred Compensation Account
established pursuant to the provisions of this Article IV. This election shall
be made by submitting a completed Compensation Deferral Agreement to the
Company. An eligible Employee who has not elected to defer Compensation pursuant
to this Section 4.02 for a given calendar year shall be permitted to commence
participation at any time during the calendar year by submitting a completed
Compensation Deferral Agreement prior to the beginning of the pay period for
which the election is to be effective. A Participant's deferral election shall
remain in effect until revoked in writing. Any such revocation shall become
effective with respect to the next pay period after receipt by the Company. Once
having revoked an election, an Employee shall be precluded from deferring
Compensation under this Section 4.02 until the beginning of the next calendar
year.

         SECTION 4.03 VESTING. A Participant shall at all times have a 100%
vested interest in amounts credited to his or her Deferred Compensation Account
pursuant to Section 4.02.

         SECTION 4.04 INVESTMENT. The amount credited to a Participant's
Deferred Compensation Account shall be invested by the Trustee in a money market
account chosen by the Plan Administrator, and gains and losses (if applicable)
shall be credited to the Participant's Deferred Compensation Account as of the
Valuation Dates. A Participant, subject to the discretion of the Trustee, may
direct the Trustee to invest the amount credited to his or her Deferred
Compensation Account in various mutual funds selected by the Plan Administrator;

receiving an allocation of either Company contributions or forfeitures under any
such Tax-Qualified Retirement Plan, the Company shall credit an amount
equivalent to the amount of such contributions and forfeitures to the Company
Contribution Account maintained on behalf of the Participant pursuant to the
provisions of this Article V. Such Excess Benefits amounts shall be calculated
as of each June 30th and paid into the Plan by the end of the calendar year. An
Employee shall be entitled to an Excess Benefits allocation during the Plan Year
only if the Employee is employed by the Company on the June 30th as of which the

of an Employee's retirement, Disability or death, employment with the Company on

a Participant from receiving either Company contributions or forfeitures under
any such Tax-Qualified Retirement Plan, the Company shall credit an amount equal
to the amount of such contributions or forfeitures of such Restricted Benefits
to the Company Contribution Account maintained on behalf of the Participant
pursuant to the provisions of this Article V. Such Restricted Benefits amounts
shall be calculated as of each June 30th and paid into the Plan by the end of
the calendar year. An Employee shall be entitled to a Restricted Benefits
allocation during the Plan Year only if the Employee is employed by the Company
on the June 30th as of which the Restricted Benefits amounts are calculated;

         Provided, that a Participant who continues his or her employment after

         Participant's Beneficiary in a lump sum amount.

         Company shall make payment to the Participant (in the event of
         termination following Disability or upon a Change in Control) or to the
         designated Beneficiary (in the event of death) in the same manner and

         Disability, the vested portion of a Participant's Deferred Compensation
         and Company Contribution Accounts shall be paid after the Participant's
         termination of employment in the same manner and to the same extent as

                DISTRIBUTION OF SUPPLEMENTAL COMPENSATION ACCOUNT

         SECTION 8.01 PAYMENT OF SUPPLEMENTAL COMPENSATION ACCOUNT.

         (a) UPON TERMINATION AFTER ATTAINMENT OF RETIREMENT AGE. Within a
         reasonable time following the first Valuation Date after the
         termination of the Participant's employment with the Company for
         reasons other than Cause on or after attainment of Early or Normal
         Retirement Age, the Company shall pay the Participant 180 monthly level
         installments of an amount determined by annuitizing the amount credited
         to the Participant's Supplemental Compensation Account assuming an 8%
         fixed rate of return during the payout period. If the Participant
         should die on or after the commencement of installment payments but
         prior to receipt of all 180 installments, the remaining installments
         shall be paid on regularly scheduled monthly payment dates to the
         Participant's Beneficiary.

         (b) UPON DEATH, DISABILITY PRIOR TO RETIREMENT AGE OR FOLLOWING A
         CHANGE IN CONTROL. If a Participant's employment with the Company is
         terminated by reason of death or Disability prior to attainment of
         Early or Normal Retirement Age or in the event of a Change in Control,
         the Company shall pay 180 installments to the Participant (in the event
         of Disability) or the Participant's Beneficiary (in the event of death)
         in the same manner and to the same extent as provided in (a) above, as
         if the Participant had retired on the date of his death, termination
         due to Disability or upon a Change in Control.

         (c) UPON OTHER TERMINATION OF EMPLOYMENT. If a Participant shall
         terminate employment with the Company without satisfying the conditions
         of (a) or (b) above, or shall terminate employment for Cause before
         satisfying the vesting provisions of Article VI, the amount credited to
         the Participant's Supplemental Compensation Account shall be forfeited.

         SECTION 8.02 PURCHASE OF ANNUITY FROM AN INSURER. To the extent that
the Company purchases an annuity from an insurance company in the name of a
Participant to satisfy in full the Company's obligations regarding the payment
of a Participant's Supplemental Compensation Account, the Company shall be
relieved of any further obligations to provide payments to such Participant
under Article VIII, and the Participant shall have recourse against the insurer
and not the Company to provide any future payments.

         SECTION 9.01 UNFUNDED ACCOUNTS. Amounts credited to a Participant's
Account under the Plan shall accumulate in a reserve account established on the
books of the Company. Amounts credited thereto shall be adjusted by a rate of
earnings or losses consistent with the before-tax rate of return realized upon
any assets used in satisfying the Company's obligations under this Plan.

         SECTION 9.02 GENERAL CREDITOR. A Participant shall be regarded as an
unsecured general creditor of the Company with respect to any rights derived by
the Participant from the existence of this Plan or the existence or aggregated
amount credited to a Participant's Account. Title to and beneficial ownership of
any Company assets whether cash, money market or mutual fund investments, life
insurance contracts or other assets which may be used by the Company from time
to time to satisfy all or any portion of its obligations for benefit payments
under the Plan, shall remain solely the property of the Company and no
Participant shall have any right to specific assets owned by the Company.

         SECTION 9.03 ESTABLISHMENT OF RABBI TRUST AND SELECTION OF TRUSTEE. The
Company may establish a Rabbi Trust by a trust agreement with a Trustee to carry
out the purposes of the Plan. The Company shall select any such trustee, who
shall be an independent third party, or corporate trustee. The Company may
modify any such trust agreement to accomplish the purposes of the Plan. Subject
to notice provisions, if any, in the Rabbi Trust agreement, the trustee may
resign by delivering a written resignation to the Company; similarly, the
Trustee may be removed by the Company at any time, upon written notice to the
Trustee. Any Rabbi Trust established hereunder shall not make the Plan "funded"
for purposes of ERISA or the Code.

         SECTION 9.04 ASSIGNMENT. No rights under this Plan may be assigned,
transferred, pledged or encumbered by the Company, Participant or Beneficiary
except by will or by the intestate laws or other laws of descent and
distribution. The obligations and rights of this Plan may be assigned by the
Company if the Company or its assets are purchased by another Corporation or are
merged into the assets of another corporation.

         SECTION 9.05 WITHHOLDING. The Trustee shall withhold from a
Participant's distribution hereunder, and the Company also shall have the right
(i) to withhold from a Participant's compensation, or (ii) to require a
Participant or Beneficiary to tender a sufficient amount of cash to the Company
to satisfy any applicable federal, state and local income and employment tax
withholding obligations derived from benefit payments hereunder. In the case of
an annuity purchased from an insurer under Article VIII, the insurer shall
withhold from the annuity a sufficient amount to satisfy any federal, state and
local income and employment tax withholding obligations derived from the benefit
payments hereunder.

any other Corporation or reorganize unless and until such succeeding Corporation
agrees to assume and discharge the obligations and rights of the Company under

all obligations under this Plan.

that term is defined in ERISA or otherwise) with respect to the Plan from any
and all claims, loss, damages, expenses (including reasonable counsel fees
approved by the Company), and liability (including any reasonable amounts paid
in settlement with the Company's approval) arising out of any act or omission of
such fiduciaries incurred in the capacity of "fiduciary" of the Plan as that
term is defined in ERISA or otherwise. The Company shall not indemnify any
fiduciary whose conduct is finally adjudicated by a court of competent

liability insurance as it shall deem necessary or appropriate to protect any
person acting as a "fiduciary" of the Plan, as that term is defined in ERISA or
otherwise, from any liability which may be incurred as a result of the
performance of fiduciary duties with respect to the Plan, other than liability
arising out of the knowing or willful misconduct of such fiduciary.
