Dietmar Hopp leaves SAP Supervisory Board

     WALLDORF, Germany, — Mar. 24, 2005 — Dietmar Hopp, founder of SAP and a member of the supervisory board since 1998, will resign from this position at the close of the next annual general meeting (AGM) of shareholders. The supervisory board therefore proposes to the AGM to elect Dr. Erhard Schipporeit, member of the board of management and CFO of E.ON AG, Dusseldorf, as a shareholder representative on the supervisory board. Dr. Schipporeit’s responsibilities on the board of management of E.ON include finance, accounting, taxes and IT. SAP’s next annual general meeting of shareholders is invited to convene at the Rosengarten, Mannheim, on May 12, 2005.

     “Dietmar Hopp has decisively marked SAP’s development as a co-founder, as a member of the executive board as well as a member of the supervisory board. His competence and his ability to motivate SAP’s employees were key to his success in leading the company. As chairman and later as a member of the supervisory board, his advice and counsel, based on his rich experience, were always in demand”, says Prof. Dr. h. c. Hasso Plattner, co-founder of SAP AG and chairman of the supervisory board.

     Dietmar Hopp is one of the founders of SAP AG. From 1988, when SAP was first listed on the stock market, until 1997, he was chairman of the executive board. From 1997 until 1998, together with Hasso Plattner, he served as chief executive officer (CEO). In 1998, Hopp was elected to the supervisory board and became its chairman. In 2003 he relinquished the role of chairman, while continuing to serve as a member of the supervisory board. Hopp, who turns 65 in April 2005, said, “it’s better to withdraw from responsible positions too early rather than too late.”
