ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On May 6, 2005, Compuware Corporation ("Compuware") entered into an
Agreement and Plan of Merger (the "Merger Agreement") with Adlex, Inc.
("Adlex"), Compuware Acquisition Corp., a newly formed and wholly-owned
Compuware subsidiary (the "Merger Sub"), and Tad Witkowicz as the Adlex
stockholder representative, contemplating the acquisition of Adlex by Compuware.
Adlex, based in Marlborough, Massachusetts, is a privately held company that
provides service delivery management technology that enables internet service
providers and enterprise customers to cost-effectively diagnose and manage
end-user experience and quality of service for business-critical applications.
The Merger Agreement provides for the merger of the Merger Sub with and into
Adlex, with Adlex surviving the merger as a wholly-owned subsidiary of
Compuware.

         The purchase price for this transaction is $35.9 million in cash plus
potential additional consideration if Compuware collects certain net license
fees within nine months after the closing. The closing of the transaction is
subject to customary approvals, consents and other conditions, and is expected
to be completed in the first quarter of Compuware's 2006 fiscal year.

         A copy of the definitive Merger Agreement is attached as Exhibit 2.6
and is incorporated herein by reference. A copy of the press release dated May
9, 2005 announcing the execution of the agreement is attached as Exhibit 99.1.
The foregoing description of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement.
