Compuware Corporation Signs Definitive Agreement to Acquire Covisint

Compuware to Support, Extend and Enhance "Automotive Industry Operating System" Productivity Solutions

DETROIT, Feb. 5 -- Compuware Corporation and Covisint, LLC (Covisint) announced today that they have entered into a definitive agreement for Compuware to acquire the products and technology of Covisint -- the company whose solutions connect the global automotive industry. Covisint has more than 135,000 users in more than 96 countries. Compuware expects that this purchase will add one to two cents per share to Compuware's earnings for its next fiscal year ending March 31, 2005.

Compuware and Covisint expect to close the transaction within 30 days, subject to customary closing contingencies.

"Combining Compuware's productivity solutions and skilled professionals with Covisint's messaging, portal and web services offerings will present a compelling package that can significantly extend cost-savings for OEMs and suppliers," said Compuware Chairman and CEO Peter Karmanos, Jr. "Compuware's financial stability, global presence and mature services and development organizations will only enhance the value Covisint is able to deliver to the automotive industry. This is an outstanding opportunity to gain synergy from extended relationships and enhanced technology."

Covisint's offerings help some of the largest companies in the world connect, communicate and collaborate through a common infrastructure, eliminating redundancies, reducing costs and increasing productivity. The majority of Covisint's staff will be retained and is expected to transition to Compuware's Detroit headquarters over the next several months.

"Now that Covisint is running mission-critical processes for the OEMs and large Tier One Suppliers they would like us to rapidly expand our capabilities," said Bob Paul, Covisint President and CEO. "Under the stewardship of Compuware we will be able to globally scale our technology offering. Compuware was a logical choice for us due to its strong local presence and similar commitment to the automotive industry."
