INFINEON CANCELS PROMOS SHAREHOLDER AGREEMENT WITH MOSEL VITELIC

Munich, Germany - October 4, 2002 - Infineon Technologies (FSE/NYSE: IFX) today
announced that is has cancelled its shareholder agreement with Mosel Vitelic on

accordance with the terms of the shareholders agreement.

Simultaneously, the product purchase agreement which establishes the rights of
both partners to purchase products from ProMOS will terminate. ProMOS can
