Wacker Chemie AG / Changes to the Management Board

WACKER’s Executive Board is Complete

Munich, Mar 13, 2008

Dr. Wilhelm Sittenthaler is to join the Executive Board of Wacker Chemie AG. A resolution to this effect was passed by the Supervisory Board at its meeting today. Wilhelm Sittenthaler will become a member of WACKER’s Executive Board on May 8, 2008. His contract lasts until 2013. Today’s appointment means that the Executive Board will continue to have four members. At the same meeting, the Supervisory Board extended Auguste Willems’ contract for another five years until 2013.

The new appointment is related to the fact that Dr. Peter-Alexander Wacker, the current President & CEO, is leaving the Executive Board. At the Annual Shareholder Meeting on May 8, 2008, he will step down and stand as a candidate for the Supervisory Board that same day. His successor as President & CEO will be Dr. Rudolf Staudigl, who has been a member of the company’s Executive Board since 1995. Wacker Chemie AG announced this change at its helm in December 2007.

Wilhelm Sittenthaler has held various managerial positions at WACKER over the last 28 years. Since May 1, 2003, he has been President & CEO of Siltronic AG, a fully-owned subsidiary of Wacker Chemie AG. In his new position on WACKER’s Executive Board, he will remain President & CEO of Siltronic.
