Board

Celanese announced today that the Board of Management decided to have new shareholder representatives appointed by court order. The current members of the Supervisory Board elected by the shareholder meeting have resigned with effect prior to the company's annual general meeting on June 15. This decision reflects the changed shareholder structure of Celanese AG as the takeover offer by Blackstone was accepted by 84.32% of the Celanese shareholders. The shareholder representatives to be newly appointed are the following:

Chinh Chu (Senior Managing Director, The Blackstone Group), Cornelius Geber (formerly Member of the Board of Management of Kuehne und Nagel), Benjamin Jenkins (Principal, The Blackstone Group), Dr. Hanns Ostmeier (Senior Managing Director, The Blackstone Group Deutschland GmbH), Dr. Ron Sommer (formerly Chairman of the Board of Management of Deutsche Telekom) and Dr. Bernd Thiemann (formerly Chairman of the Board of Management of DZ-Bank).

In a reaction to substantially decreased trading volumes at the New York Stock Exchange, the Board of Management also authorized the submission of all filings with the NYSE and the U.S. Securities and Exchange Commission necessary to de-list the company's shares from the NYSE. The trading of the company's shares on the NYSE is expected to cease in the second quarter of 2004. Celanese AG's Board of Management further authorized taking all necessary actions to enter into a domination and profit and loss transfer agreement (Beherrschungs- und Ergebnisabfuehrungsvertrag) with BCP Crystal Acquisition GmbH & Co. KG, an indirect wholly-owned subsidiary of Blackstone Crystal Holdings Capital Partners IV Ltd. The agreement is subject to approval by Celanese AG's Supervisory Board and the affirmative vote of at least 75% of the share capital represented at an extraordinary shareholders' meeting of Celanese AG, which is expected to be convened in the third quarter of 2004.
