ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On March 21, 2005, Compuware Corporation ("Compuware") entered into a
definitive Settlement Agreement with International Business Machines Corporation
("IBM") to settle all of the outstanding litigation and related disputes among

         Pursuant to the terms of the Settlement Agreement:

         1)       IBM will pay a minimum of $140 million over four years for
                  licenses to Compuware software products and maintenance of
                  Compuware software products, and will offer to purchase a
                  minimum of $260 million of Compuware services over four years.
                  These commitments are as follows:



                                               LICENSES AND MAINTENANCE                    SERVICES
                                               ------------------------                    --------

                  4/1/06 - 3/31/07                $40 million                            $60 million
                  4/1/07 - 3/31/08                $40 million                            $80 million
                  4/1/08 - 3/31/09                $40 million                            $80 million
                                                  -----------                            -----------
                                       Total      $140 million                           $260 million


         2)       IBM and Compuware have entered into an irrevocable, perpetual
                  patent cross-licensing agreement, covering patents related to
                  both companies' businesses currently issued or issuing on or
                  prior to March 21, 2009; and
         3)       The parties have agreed to dismiss all claims in the above
                  litigation with prejudice and have granted mutual releases.

         At this time, Compuware believes that the impact, if any, of the
settlement on Compuware's fourth quarter 2005 results will be insignificant.

incorporated herein by reference. A copy of the press release dated March 22,
2005 announcing the execution of the Settlement Agreement is attached as Exhibit
