(DALLAS) July 24, 2006 --- Celanese Corporation (NYSE: CE), a global hybrid chemical company, today announced that Martin G. McGuinn and John K. Wulff have been nominated for election to the Celanese board of directors. The election will be held at a special meeting of shareholders on August 14, 2006.

Until February 2006, McGuinn was chairman and chief executive officer of Mellon Financial Corporation, where he spent 25 years in a number of positions. McGuinn recently concluded a one-year term as chairman of the Financial Services Roundtable and also served as president of the Federal Reserve Board’s advisory council in 2005. McGuinn also serves on several nonprofit boards, including Carnegie Mellon University, the Carnegie Museums of Pittsburgh and the University of Pittsburgh Medical Center. Upon election, McGuinn is expected to serve on the company’s audit committee as an independent director.  

Wulff has been the non-executive chairman of the board of Hercules Incorporated since July 2003. Before that, he served as a member of the Financial Accounting Standards Board from July 2001 until June 2003. Wulff was previously chief financial officer of Union Carbide Corporation from 1996 to 2001. During his 14 years at Union Carbide, he also served as vice president and principal accounting officer from January 1989 to December 1995, and controller from July 1987 to January 1989. Wulff was also a partner of KPMG and predecessor firms from 1977 to 1987. Currently, he serves as director on the boards of Moody’s Corporation, Sunoco Incorporated, and Fannie Mae. Upon election, Wulff is expected to serve on the company’s compensation committee as an independent director.

Upon approval by shareholders, the Celanese board will be comprised of 11 directors, which will include 6 independent directors. Due to the May 2006 sale of shares by funds affiliated with The Blackstone Group, L.P., the New York Stock Exchange required that the Celanese board of directors be comprised of a majority of independent directors within 12 months of the transaction. The proposed change to the board marks an accelerated compliance with this requirement. The company had previously been exempt from the requirement as a result of being a controlled company.
