     On March 8, 2006, Celanese AG announced that pursuant to an instruction from Celanese Europe Holdings GmbH & Co. KG (formerly known as BCP Crystal Acquisition GmbH & Co.

     The information set forth in Item 6 is hereby amended and supplemented with the following:

     On March 6, 2006, Celanese AG announced that it has reached a settlement with 11 plaintiff shareholders. The plaintiffs had filed actions with the Regional Court (Landgericht) of Frankfurt am Main for avoidance or nullity, respectively, of (i) the resolution of the shareholders’ meeting of Celanese AG of July 30/31, 2004 to consent to the conclusion of the Domination Agreement (Beherrschungs- und Gewinnabführungsvertrag) with the Purchaser (ii) the resolution of the shareholders’ meeting of Celanese AG of May 19/20, 2005 to confirm such consent; and (iii) further resolutions passed at the shareholders’ meetings of July 30/31, 2004 and May 19/20, 2005. The settlement provides for the Purchaser to offer at least EUR51.00 per share of Celanese AG as cash consideration to each shareholder who will cease to be a shareholder of Celanese AG pursuant to the proposed squeeze-out described above. The Purchaser further agrees to make early payment of the guaranteed dividend owed pursuant to Section 4 of the Domination Agreement for the financial year 2005/2006, ending on September 30, 2006. Such guaranteed annual payment will be made on the first banking day following the ordinary shareholders’ meeting of Celanese AG for the financial year 2004/2005, which will take place in May 2006. To receive the early payment, the respective minority shareholder must deliver on his own behalf and on behalf of the legal successors to his shares a declaration to the effect that (i) his claim for payment of compensation for the financial year 2005/2006 pursuant to the Domination Agreement is settled by such early payment, and that (ii) in this respect, he indemnifies the Purchaser against compensation claims by any legal successors to his shares. The plaintiff parties to the settlement withdrew all actions filed by them in connection with the Domination Agreement as well as other ancillary litigation and the plaintiff parties recognized the validity of the Domination Agreement.
