B common stock of Celanese Corporation are owned by Blackstone Capital Partners (Cayman) Ltd. 1 ("Cayman 1"), Blackstone 
Capital Partners (Cayman) Ltd. 2 ("Cayman 2"), and Blackstone Capital Partners (Cayman) Ltd. 3 ("Cayman 3" and collectively

may be deemed to be the beneficial owner of the shares of Series B common stock held by the Cayman Entities owned by such 
Blackstone Funds. Blackstone Management Associates (Cayman) IV L.P. ("BMA") is the general partner of each of the 
Blackstone Funds and may, therefore, be deemed to be the beneficial owner of the share of Series B common stock held by the 
Cayman Entities. BLRA is the general partner of BMA and may, therefore, be deemed to be the beneficial owner of shares of 
Series B common stock held by the Cayman Entities. 
Mr. O'Neill disclaims beneficial ownership of shares of the Series B common stock that may be deemed beneficially owned by 
BLRA or any other affiliates of The Blackstone Group set forth above. This report shall not be deemed an admission that Mr. 
O'Neill is the beneficial owner of, or has any pecuniary interest in, such securities for purposes of Section 16 of the 
Exchange Act of 1934, as amended, or for any other purpose.
