ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         This Amendment No. 12 is being filed as a result of transactions,
including both acquisitions and dispositions, of the Company's Common Stock, as
described in Item 5(c).

         Mr. Karmanos, Mr. Thewes, Mr. Lobsinger, Mr. Prowse, Mr. Nathan and the
Cutting Trust acquired the shares beneficially owned by them at various times
from April 1973 through November 1992 for consideration which did not exceed
$1,203,252 in the aggregate and the source of which was their own personal
funds. Of the shares of Common Stock beneficially owned by GAP II and
GAP-Compuware, an aggregate of 5,876,371 shares of Common Stock were acquired by
them on December 15, 1992 upon the conversion and redemption of 729,395 shares
of the Company's Convertible Participating Preferred Stock, which shares of
Convertible Participating Preferred Stock were acquired from the Company in
November 1989 for the aggregate consideration of approximately $30,000,000, the
source of which was their working capital (GAP II and GAP-Compuware subsequently
sold an aggregate of 2,130,000 of these shares of Common Stock in the IPO). GAP
II and GAP-Compuware acquired the remaining 1,411,270 shares of Common Stock
beneficially owned by them in June 1990 at a price per share of $4.33, the
source of which was their own working capital. The Long Family Trust, the Long
Unitrust and the Harris Family Trust acquired the shares of Common Stock
beneficially owned by each of them in August 1990 and January 1991 as a result
of a merger of the Company and Centura Software which occurred in August 1990.
The Karmanos Partnership, Glendening Karmanos, Thewes 1995 Trust, Thewes 1997
Trust, W. and K. Long Unitrust, Harris Unitrust, J. Cutting Trust, Cutting
Foundation and General Atlantic Partners became members of the group when shares
held by original group members were transferred. GAP-Amsterdam became a member
of the group when the Company acquired all of the stock of Uniface Holding,
B.V., a Netherlands corporation ("Uniface"). GAP-Amsterdam 's shares in Uniface
were exchanged for shares in the Company pursuant to the terms of the Exchange
Agreement.

ITEM 4.  PURPOSE OF TRANSACTION

         All of the members of the group except Glendening Karmanos and the
Thomas Thewes 1998 Trust have agreed, pursuant to two separate shareholder
agreements described in greater detail in Item 6 below, to grant to Peter
Karmanos, Jr. the power to vote the shares of Common Stock which they own for a
period of ten years beginning on the effective date of the IPO Registration
Statement, which date was December 15, 1992. In the event that Mr. Karmanos
shall die before the end of such ten year period, Mr. Thomas Thewes, if he
survives Mr. Karmanos, shall receive the right to vote the group's shares of
Common Stock for the remainder of such period. Glendening Karmanos and the
Thewes 1998 Trust have agreed, pursuant to separate shareholder agreements
described in greater detail in Item 6 below, to grant to Peter Karmanos, Jr. the
power to vote the shares of Common Stock which they own. As a result of such
proxies, Mr. Karmanos now controls the vote of approximately 10.1% of the issued
and outstanding shares of Common Stock (11.2% assuming the exercise of all stock
options exercisable within 60 days of the date hereof held by Mr. Karmanos and
the other members of the group).

         Mr. Karmanos and Mr. Thewes are the founders of the Company. The other
group members have worked with or for or have been shareholders of the Company
for a significant period of time. As a result of such association, the group
members share certain common views regarding the Company and its direction for
the future. Thus, the purpose of granting such proxies to Mr. Karmanos was to
enable him to exercise voting control over the affairs of the Company in order
that these common views could effectively be put into place.

         As to item 5(c), Mr. Lobsinger acquired shares of the Company's Common
Stock on the open market since September 30, 1996. To the best of the
undersigned's knowledge neither Mr. Lobsinger nor any member of the group has
any present intention, other than in the ordinary course of business, of
engaging in any of the following types of activities:

         (a) the acquisition by any person of additional securities of the
Company, or the disposition of securities of the Company, although various
members of the group are free to sell in open market transactions or make gifts,
should they so desire, from time to time and have indicated they may do so if
they decide the time and/or market price, are in their view appropriate;

         (b)   an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Company or any of its subsidiaries;

         (c)   a sale or transfer of a material amount of assets of the Company
or any of its subsidiaries;

         (d)   any change in the present board of directors or management of the
Company, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the board;

         (e)   any material change in the present capitalization or dividend
policy of the Company;

         (f)   any other material change in the Company's business or corporate
structure;

         (g)   changes in the Company's articles of incorporation or bylaws 
which may impede the acquisition of control of the Company by any person;

         (h)   causing a class of securities of the Company to be delisted from
a national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;

         (i)   causing a class of equity securities of the Company to become
eligible for termination of registration pursuant to Section 12(g)(4) of the
Act; or

         (j)   any action similar to any of those enumerated above.

Director of the Company, a ten-year proxy to vote the shares of Common Stock
held by them (11,753,737 shares in the aggregate, which includes 725,564 shares
subject to options exercisable within 60 days of the date thereof) or acquired
by them during the term of the agreement. In addition, on October 22, 1992, GAP
II and GAP-Compuware entered into a shareholder agreement with Mr. Karmanos
granting him a ten-year proxy to vote their shares of Common Stock (5,149,521
shares in the aggregate). Pursuant to both such agreements the proxies will be
exercisable by Thomas Thewes if he survives Mr. Karmanos. Shareholders under
both such agreements may sell their shares at any time in bona fide open market
transactions free of the proxies granted to Mr. Karmanos. Under their agreement,
GAP II and GAP-Compuware have also agreed for a ten-year period not to increase
their ownership of Common Stock. In addition, pursuant to the agreement among
the Company, Peter Karmanos, Jr., Thomas Thewes, GAP II and GAP-Compuware, in
the event Peter Karmanos, Jr. dies or is declared mentally incompetent prior to

outstanding Common Stock of the Company, the selection of the Chief Executive
Officer of the Company shall require the affirmative vote of at least 63% of the
number of members of the Board of Directors.

         Such agreement also provides that GAP II and GAP-Compuware are
entitled, for so long as they and their affiliates together shall hold in the
aggregate at least five (5%) percent of the outstanding shares of Common Stock,
to designate one director to the Board of Directors of the Company, and Mr.
Karmanos and Mr. Thewes have agreed that they will vote their shares and the
shares over which they hold proxies for the election of such director.

agreement pursuant to which she granted to Peter Karmanos, Jr., Chairman of the

                              COMPUWARE CORPORATION
                              SHAREHOLDER AGREEMENT

        THIS SHAREHOLDER AGREEMENT ("Agreement") is made as of June 9, 1998,
among Compuware Corporation, a Michigan corporation ("Compuware") Peter 
Karmanos, and Thomas Thewes, all of whom hereby agree that:

        A. The parties to this agreement are also parties to a certain Voting
Agreement dated November 5, 1992, as amended, which affects certain shares of
Compuware stock owned by Mr. Thewes; and

        B. Mr. Thewes is currently contemplating making a charitable gift of
200,000 shares from his stock that is subject to the 1992 agreement, as amended,
and desires to ensure that these shares will not be considered property
attributable to him for estate tax purposes at any time after completing the
gift; and

        C. The form of gift contemplated by Mr. Thewes to ensure these shares
will not be considered property attributable to him for estate tax purposes at
any time after completing the gift is not permissible under the 1992 agreement
without Mr. Karmanos's consent; and

        D. Mr. Karmanos is not willing to consent to an unrestricted release of
these 200,000 shares from the 1992 agreement unless the terms of this agreement
are substituted in place of the terms of the 1992 agreement; and

        E. To ensure that these shares will not be considered property
attributable to him for estate tax purposes at any time after completing the
gift, and to accomplish the charitable purposes of the recipient, Mr. Thewes is
willing to accept the terms of this Agreement on his own behalf and in
limitation of the rights of any subsequent owners of the shares; and

        F. Compuware is willing to be a party to this Agreement to help
effectuate the desire of Mr. Thewes and Mr. Karmanos.


        With that in mind, the parties wish to enter into an agreement which for
a period of time will govern the manner in which the 200,000 shares to be
transferred by Mr. Thewes will be voted, and limit subsequent owners' ability to
transfer them.
