may determine.

Amendment to Articles of Incorporation:

               Any resolution of the Board of Directors establishing and
designating a series of Preferred Stock and fixing and determining the relevant

share for share, and each holder of Common Stock is entitled to one vote per
share.  Except to the extent required by law, no holder of Common Stock shall
have the right in voting for directors to cumulate his shares and give one

the same principle among as many candidates as he shall determine.  Except as
otherwise stated herein, the shares of Common Stock shall have the rights and
privileges provided by Michigan law.

                           PREFERRED AND COMMON STOCK

or to





                                       6

purchase any part of a new or additional issue of stock or any other reacquired
shares of stock of any class whatsoever or of any securities convertible into

The Corporation Company.


                                   ARTICLE V

               Whenever a compromise or arrangement or any plan of
reorganization of this corporation is proposed between this corporation and its
creditors or any class of them and/or between this corporation and its
shareholders or any class of them, any court of equity jurisdiction within the
state of Michigan, may on the application of this corporation or of any
creditor or any shareholder thereof, or on the application of any receiver or
receivers appointed for this corporation, order a meeting of the creditors or
class of creditors, and/or of the shareholders or class of shareholders, as the
case may be, to be affected by the proposed compromise or arrangement or
reorganization, to be summoned in such manner as said court directs.  If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the shareholders or class of shareholders, as the
case may be, to be affected by the proposed compromise or arrangement or
reorganization, agree to any compromise or arrangement or to any reorganization
of this corporation as a consequence of such compromise or arrangement, said
compromise or arrangement and said reorganization shall, if sanctioned by the
court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the shareholders or class of
shareholders, as the case may be, and also on this corporation.


                                   ARTICLE VI

               (a)      No director of the Corporation shall be personally
liable to the Corporation or its shareholders for monetary damages for breach
of fiduciary duty as a director, provided that the foregoing shall not
eliminate or limit





                                       7
   8





the liability of a director for any of the following:  (i) breach of the
director's duty of loyalty to the Corporation or its shareholders; (ii) acts or
omissions not in good faith or that involve intentional misconduct or knowing
violation of law; (iii) a violation of Section 551(1) of the Michigan Business
Corporation Act; (iv) a transaction from which the director derived an improper
personal benefit; or (v) an act or omission occurring before the date on which
the Article VI became effective.  If the Michigan Business Corporation Act
hereafter is amended to authorize the further elimination or limitation of the
liability of directors, then the liability of a director of the Corporation, in
addition to the limitation on personal liability contained herein, shall be
limited to the fullest extent permitted by the amended





                                       8
   9





Michigan Business Corporation Act.  No amendment or repeal of this Article VI
shall apply to or have any effect on the liability or alleged liability of any
director of the Corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment or repeal.

               (b)(1)  Each individual who was or is made a party or is
threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that such individual, or an
individual of whom such individual is the legal representative, (i) is or was a
director or officer of the Corporation, or (ii) is or was serving (at such time
as such individual is or was a director or officer of the Corporation) at the
request of the Corporation as a director, officer, partner, trustee,
administrator, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans (hereinafter "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a director, officer,
partner, trustee, administrator, employee or agent or in any other capacity
while serving as a director, officer, partner, trustee, administrator, employee
or agent, shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the Michigan Business Corporation Act, as the same
exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment), against all expense, liability and loss
(including attorneys' fees, judgments, fines and amounts paid or to be paid in
settlement) reasonably incurred or suffered by such indemnitee in connection
therewith and such indemnification shall continue as to an indemnitee who has
ceased to be a director or officer and shall inure to the benefit of such
indemnitee's heirs, executors and administrators; provided, however, that,
except as provided in paragraph (b)(2) hereof with respect to proceedings to
enforce rights to indemnification, the Corporation shall indemnify any such
indemnitee seeking indemnification in connection with a proceeding (or part
thereof) initiated by such indemnitee only if such proceeding (or part thereof)
was authorized by the Board of Directors of the Corporation.  The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition (hereinafter
"advances"); provided, however, that the payment of such expenses incurred by
an indemnitee in advance of the final disposition of a proceeding, shall be
made only upon delivery to the Corporation of an undertaking, by or on behalf
of such indemnitee, to repay all advances if it shall ultimately be





                                       9
   10





determined by final judicial decision that such indemnitee is not entitled to
be indemnified under this Section or otherwise.  The Corporation may, by action
of its Board of Directors or by action of any person to whom the Board of
Directors has delegated such authority, provide indemnification to other
employees and agents of the Corporation with the same scope and effect as the
foregoing indemnification.

               (b)(2)  If a claim under paragraph (b)(1) of this Section is not
paid in full by the Corporation within thirty days after a written claim has
been received by the Corporation, the indemnitee may at any time thereafter
bring suit against the Corporation to recover the unpaid amount of the claim.
If





                                       10
   11





successful in whole or in part in any such suit or in a suit brought by the
Corporation to recover advances, the indemnitee shall be entitled to be paid
also the expense of prosecuting or defending such claim.  In any action brought
by the indemnitee to enforce a right hereunder (other than an action brought to
enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking has been tendered to the
Corporation) it shall be a defense that, and in any action brought by the
Corporation to recover advances the Corporation shall be entitled to recover
such advances if, the indemnitee has not met the applicable standard of conduct
set forth in the Michigan Business Corporation Act.  Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or
its shareholders) to have made a determination prior to the commencement of
such action that indemnification of the indemnitee is proper in the
circumstances because the indemnitee has met the applicable standard of conduct
set forth in the Michigan Business Corporation Act, nor an actual determination
by the Corporation (including its Board of Directors, independent legal
counsel, or its shareholders) that the indemnitee has not met such applicable
standard of conduct, shall be a defense to an action brought by the indemnitee
or create a presumption that the indemnitee has not met the applicable standard
of conduct.  In any action brought by the indemnitee to enforce a right
hereunder or by the Corporation to recover payments by the Corporation of
advances, the burden of proof shall be on the Corporation.

               (b)(3)  The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition
conferred in this Article shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Articles of Incorporation, Bylaw, agreement, vote of shareholders or
disinterested directors or otherwise.

               (b)(4)  The Corporation may maintain insurance, at its expense,
to protect itself and any director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Michigan Business Corporation Act.

               These Restated Articles of Incorporation were duly adopted on
the 5th day of February, 1996, in accordance with the provisions of Section 642
of the Act and were duly adopted by the Board of Directors without a vote of
the shareholders.

                     ARTICLES OF INCORPORATION DETERMINING
                   THE TERMS OF THE SERIES A PREFERRED STOCK

                                       of

                             COMSHARE, INCORPORATED



               It is certified that:

               FIRST:  That the name of the corporation is Comshare,
Incorporated (the "Corporation").

               SECOND:  The Corporation identification number (CID) assigned by
the Bureau is: 085-703.

               THIRD:  The location of its registered office is: 30600
Telegraph Road, Bingham Farms, Michigan  48025.

               FOURTH:  That pursuant to the authority conferred upon the Board
of Directors by the Articles of Incorporation of said Corporation, the Board of
Directors of the Corporation on September 12, 1996, duly adopted the following
resolution creating a series of 200,000 shares of Preferred Stock, no par
value, designated as Series A Preferred Stock:

               RESOLVED, That it is hereby declared to be in the best interests
of the Corporation that the Articles of Incorporation of the Corporation, as
amended to date, be further amended to create a new series of Preferred Stock
to consist of 200,000 shares and to be designated as Series A Preferred Stock,
no par value, and to determine the preferences, limitations and relative rights
of the Series A Preferred Stock by adding the following to Article V of such
Articles of Incorporation to read as follows:

               SERIES A PREFERRED STOCK, NO PAR VALUE

               A.       Designation and Amount.  The shares of such series 




                                      1
   14


shall be designated as "Series A Preferred Stock, no par value," and the number
of shares constituting such series shall be 200,000.  Such number of shares may
be increased or decreased by resolution of the Board of Directors of the
Corporation; provided, that no decrease shall reduce the number of shares of
Series A Preferred Stock to a number less than the number of shares then
outstanding plus the number of shares reserved for issuance upon the exercise
of outstanding options,

                                      2

   15



rights or warrants or upon the conversion of any outstanding securities issued
by the Corporation convertible into Series A Preferred Stock.

               B.       Dividends and Distributions.

                        (1)     Subject to any prior and superior rights of the
holders of any series of Preferred Stock ranking prior and superior to the
shares of Series A Preferred Stock with respect to dividends that may be
authorized by the Articles of Incorporation, the holders of shares of Series A
Preferred Stock shall be entitled prior to the payment of any dividends on
shares ranking junior to the Series A Preferred Stock to receive, when, as and
if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the last day of January, April,
July and October in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $1.00 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock,
par value $1.00 per share, of the Corporation (the "Common Stock") since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock.  In the event the Corporation
shall at any time after September 12, 1996 (the "Rights Declaration Date") (i)
declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the amount to
which holders of shares of Series A Preferred Stock were entitled immediately
prior to such event under clause (b) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of

                                      3

   16


Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

                        (2)     The Corporation shall declare a dividend or
distribution on the Series A Preferred Stock as provided in paragraph (1) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in
the event no

                                      4

   17


dividend or distribution shall have been declared on the Common Stock during
the period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

                        (3)     Dividends shall begin to accrue and be
cumulative on outstanding shares of Series A Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of Series
A Preferred Stock, unless the date of issue of such shares is prior to the
record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is
a date after the record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive a quarterly dividend and before
such Quarterly Dividend Payment Date, in either of which events such dividends
shall begin to accrue and be cumulative from such Quarterly Dividend Payment
Date.  Accrued but unpaid dividends shall not bear interest.  Dividends paid on
the shares of Series A Preferred Stock in an amount less than the total amount
of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive payment of a dividend or distribution declared thereon, which record
date shall be no more than 30 days prior to the date fixed for the payment
thereof.

                        (4)     Dividends in full shall not be declared or paid
or set apart for payment on the Series A Preferred Stock for a dividend period
terminating on the Quarterly Dividend Payment Date unless dividends in full
have been declared or paid or set apart for payment on the Preferred Stock of
all series (other than series with respect to which dividends are not
cumulative from a date prior to such dividend date) for the respective dividend
periods terminating on such dividend date.

               C.       Voting Rights.  The holders of shares of Series A
Preferred Stock shall have the following voting rights:

                                      5

   18


                        (1)     Subject to the provision for adjustment
               hereinafter set forth, each share of Series A Preferred Stock
               shall entitle the holder thereof to 100 votes on all matters
               voted on at a meeting of the shareholders of the Corporation.
               In the event the Corporation shall at any time after the Rights
               Declaration Date (i) declare any dividend on Common Stock
               payable in shares of Common Stock, or (ii)

                                      6

   19

               subdivide the outstanding Common Stock, or (iii) combine the
               outstanding Common Stock into a smaller number of shares, then
               in each such case the number of votes per share to which holders
               of shares of Series A Preferred Stock were entitled immediately
               prior to such event shall be adjusted by multiplying such number
               by a fraction the numerator of which is the number of shares of
               Common Stock outstanding immediately after such event and the
               denominator of which is the number of shares of Common Stock
               that were outstanding immediately prior to such event.

                        (2)     Except as otherwise provided herein, in any
               other Amendment to the Articles of Incorporation of the
               Corporation or by law, the holders of shares of Series A
               Preferred Stock and the holders of shares of Common Stock and
               any other capital stock of the Corporation having general voting
               rights shall vote together as one voting group on all matters
               voted on at a meeting of shareholders of the Corporation.

                        (3)     Except as set forth herein or by law, holders
               of Series A Preferred Stock shall have no special voting rights
               and their consent shall not be required (except to the extent
               they are entitled to vote with holders of Common Stock as set
               forth herein) for taking any corporate action.

               D.       Certain Restrictions.

                        (1)     Whenever quarterly dividends or other dividends
or distributions payable on the Series A Preferred Stock as provided in Section
B. are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the Corporation shall not:

                        (a)     declare or pay dividends on, or make any other
               distributions on, any shares of stock ranking junior (either as
               to dividends or upon liquidation, dissolution or winding up) to
               the Series A Preferred Stock;

                                      7

   20


                        (b)     declare or pay dividends on or make any other
               distributions on any shares of stock ranking on a parity (either
               as to dividends or upon liquidation, dissolution or winding up)
               with the Series A Preferred Stock, except dividends paid ratably
               on the Series A Preferred Stock and all such parity stock on
               which dividends are payable or in arrears in proportion to the
               total amounts to which the holders of all such shares are then
               entitled;

                                      8

   21

                        (c)     redeem or purchase or otherwise acquire for
               consideration shares of any stock ranking junior (either as to
               dividends or upon liquidation, dissolution or winding up) to the
               Series A Preferred Stock, provided that the Corporation may at
               any time redeem, purchase or otherwise acquire shares of any
               such junior stock in exchange for shares of any stock of the
               Corporation ranking junior (either as to dividends or upon
               dissolution, liquidation or winding up) to the Series A
               Preferred Stock;

                        (d)     redeem or purchase or otherwise acquire for
               consideration any shares of Series A Preferred Stock or any
               shares of stock ranking on a parity with the Series A Preferred
               Stock, except in accordance with a purchase offer made in
               writing or by publication (as determined by the Board of
               Directors) to all holders of such shares and the Series A
               Preferred Stock upon such terms as the Board of Directors, after
               consideration of the respective annual dividend rates and other
               relative rights and preferences of the respective series and
               classes, shall determine in good faith will result in fair and
               equitable treatment among the respective series or classes.

                        (2)     The Corporation shall not permit any subsidiary
of the Corporation to purchase or otherwise acquire for consideration any
shares of stock of the Corporation unless the Corporation could, under
paragraph (1) of this Section D, purchase or otherwise acquire such shares at
such time and in such manner.

               E.       Liquidation, Dissolution or Winding Up.

                        (1)     Upon any liquidation, dissolution or winding up
of the Corporation, no distribution shall be made to the holders of shares of
stock ranking junior (either as to dividends or upon liquidation, dissolution
or winding up) to the Series A Preferred Stock unless, prior thereto, the
holders of shares of Series A Preferred Stock shall have received $100.00 per
share, plus an amount equal to accrued and unpaid dividends and distributions
thereon, whether or not declared, to the date of such payment (the "Series A
Liquidation Preference").  Following the payment of the full amount of the
Series A

                                      9

   22


Liquidation Preference, no additional distributions shall be made to the
holders of shares of Series A Preferred Stock unless, prior thereto, the
holders of shares of Common Stock shall have received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i) the Series
A Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in
subparagraph (3) below to reflect such events as stocks splits, stock dividends
and recapitalizations

                                     10

   23


with respect to the Common Stock) (such number in clause (ii), the "Adjustment
Number").  Following the payment of the full amount of the Series A Liquidation
Preference and the Common Adjustment in respect of all outstanding shares of
Series A Preferred Stock and Common Stock, respectively, holders of Series A
Preferred Stock and holders of shares of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed, with
the holders of Series A Preferred Stock entitled to receive an aggregate per
share amount equal to 100 times (as appropriately adjusted as set forth in
subparagraph (3) below to reflect such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock) the aggregate amount to
be distributed per share to holders of shares of Common Stock.

                        (2)     In the event, however, that there are not
sufficient assets available to permit payment in full of the Series A
Liquidation Preference and the liquidation preferences of all other series of
Preferred Stock, if any, which rank on a parity with the Series A Preferred
Stock, then such remaining assets shall be distributed ratably to the holders
of such parity shares and the Series A Preferred Stock in proportion to their
respective liquidation preferences.

                        (3)     In the event the Corporation shall at any time
after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the Adjustment Number in effect immediately prior to
such event shall be adjusted by multiplying such Adjustment Number by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to
such event.

               F.       Merger, Consolidation, etc.  In case the Corporation
shall enter into any merger, consolidation, combination or other transaction in
which the shares of Common Stock are exchanged or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the

                                     11

   24


provision for adjustment hereinafter set forth) equal to 100 times the
aggregate amount of stock, securities, cash and/or any other property (payable
in kind), as the case may be, into which or for which each share of Common
Stock is changed or exchanged.  In the event the Corporation shall at any time
after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine

                                     12

   25


the outstanding Common Stock into a smaller number of shares, then in each such
case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

               G.       Redemption.  The shares of Series A Preferred Stock 
shall not be redeemable.

               H.       Ranking.  The Series A Preferred Stock shall rank
junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and other distribution of assets, unless, in accordance
with authorization in the Articles of Incorporation, the terms of any such
series shall provide otherwise.

               I.       Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become authorized but
unissued shares of preferred stock and may be reissued as part of a new series
of preferred stock subject to the conditions and restrictions on issuance set
forth herein, in the Articles of Incorporation, or in any other Amendment to
the Articles of Incorporation creating a series of preferred stock or any
similar stock or as otherwise required by law.

               J.       Amendment.  The Articles of Incorporation of the
Corporation shall not be further amended in any manner which would alter or
change the powers, preferences or special rights of the Series A Preferred
Stock so as to affect them adversely without the affirmative vote of the
holders of a majority of the outstanding shares of Series A Preferred Stock,
voting separately as one voting group.

               K.       Fractional Shares.  Series A Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of

                                     13

   26


holders of Series A Preferred Stock.

               FIFTH:  That this Amendment to the Articles of Incorporation of
the Corporation was duly adopted by the Board of Directors of the Corporation
on September 12, 1996, without shareholder action, which shareholder action was
not required.

                                     14

   27

               IN WITNESS WHEREOF, we have executed and subscribed this
Certificate and do affirm the foregoing as true this 16th day of September,
1996.
