Celanese Names Gallagher President, Acetyls and Celanese Asia; Sterin Named Chief Financial Officer.

DALLAS -- Celanese Corporation (NYSE: CE), a global hybrid chemical company, today announced the appointment of John J. Gallagher III, executive vice president and chief financial officer, to the position of executive vice president and president, Acetyls and Celanese Asia, effective immediately. Gallagher will relocate to the Acetyls and Celanese Asia headquarters in Shanghai, China.

Steven M. Sterin, vice president and corporate controller, has been named senior vice president and chief financial officer, replacing Gallagher, effective immediately.

The organizational changes became necessary following the recent diagnosis that John O'Dwyer, current president, Acetyls and Celanese Asia, has a very serious illness that requires him to leave his position. O'Dwyer will continue to serve in an advisory capacity with the company.

"The entire Celanese organization appreciates John's significant contributions to the company and supports his need to focus completely on his health," said Chairman and CEO David N. Weidman.

"John Gallagher and Steven Sterin have been instrumental in the execution of our corporate strategy and in driving improvements in their organizations," Weidman said. "As Celanese executive vice president, John has been integral in setting the company's strategy and guiding its operations."

Gallagher, 43, has more than 20 years of experience in the chemicals industry, serving as CEO of Great Lakes Chemical prior to joining Celanese, with previous positions as CFO of UOP LLC and chief financial officer of the Bendix division of AlliedSignal, Inc. He has a bachelor's degree in accounting from the University of Delaware.

Sterin, 35, has been vice president and corporate controller at Celanese since 2005 and has led significant company projects, including Sarbanes-Oxley compliance and implementation of a five-day accounting closing. He previously served as director of finance and controller for Celanese Chemicals. He joined the company in 2003, following seven years in global tax, treasury and finance positions for Reichhold Inc., a composite and coating resins manufacturer.
