MUNICH, Germany--(BUSINESS WIRE)--Jan. 27, 2003

The Hsinchu District Court in Taiwan has approved both of Infineon's injunction applications.

Following this ruling two Infineon employees will immediately resume office, which were illegally removed at the Extraordinary Shareholder Meeting of ProMOS on January 10. Angela Shih will serve as Supervisor and Michael Buckermann as member of the ProMOS Board of Directors.

Infineon appreciates the prompt decision by the Hsinchu District Court in this matter and is prepared to take other appropriate actions to defend its rights as a shareholder of ProMOS.

Effective immediately, Infineon terminates the technology license agreement with ProMOS due to a serious breach of contract as ProMOS is supplying all products manufactured with Infineon technology to Mosel Vitelic and due to destruction of the relationship of trust between the contract partners which is inevitably necessary for such a license agreement.

As a result of this termination, ProMOS from now on will not be allowed to manufacture products based on Infineon technology.

Infineon and Mosel Vitelic signed a shareholders agreement for the foundation of the joint venture ProMOS in 1996, which supplied all DRAM products manufactured on the licensed Infineon technology to Infineon. Infineon then supplied Mosel Vitelic with DRAM products. However, there is no more a basis to continue this cooperation because of repeated violations of the shareholders agreement by Mosel Vitelic, the breach of the license agreement by ProMOS and further measures by Mosel Vitelic, which controls the ProMOS board, impairing the partnership.
