Sergio Marchionne and Peter Voser will not stand for re-election to the Board of Directors of UBS AG

Sergio Marchionne, senior independent director of the Board of Directors of UBS AG, and Peter Voser will not stand for re-election to the Board of UBS AG at the general assembly of 14 April 2010.

UBS has announced that Sergio Marchionne, senior independent director of the Board of Directors, and Peter Voser have decided not to stand for re-election to the Board of UBS AG at the annual general meeting (AGM) which will take place on 14 April 2010. Sergio Marchionne and Peter Voser would both like in future to focus on their current demanding management positions and have therefore decided not to seek any further mandates at UBS.

Sergio Marchionne is chief executive officer (CEO) of Fiat S.p.A., Turin, and Fiat Group Automobiles as well as CEO of Chrysler Group LLC and chairman of CNH Case New Holland, a Fiat Group company. He was elected to the BoD at the AGM 2007 and appointed independent vice chairman and senior independent director in 2008. He is a member of the governance and nominating committee and of the strategy committee.

Peter Voser, CEO and executive BoD member of Royal Dutch Shell plc in London, was elected to the BoD at the AGM 2005. He is a member of the governance and nominating committee and of the strategy committee.

Kaspar Villiger, Chairman of the Board of UBS, said of these decisions: "I would like to thank the outgoing board members Sergio Marchionne and Peter Voser for their strong contributions to the management of our firm. With their comprehensive economic and entrepreneurial competence they supported UBS in difficult times and provided significant input to the stabilization and the successful initiation of the turnaround of our company."

UBS will provide information at a later stage regarding candidates to succeed the outgoing board members.
