Item 8.01 Other Events.

On July 24, 2014, Rockwood Specialties Group, Inc. (“Rockwood”), an indirect subsidiary of Rockwood Holdings, Inc. (the “Company”) and Huntsman International LLC (“Huntsman”), amended the Stock Purchase Agreement (the “Stock Purchase Agreement”), dated September 17, 2013, among Rockwood, the Company and Huntsman, as amended, to provide for an extension of the outside date (as defined in the Stock Purchase Agreement) for the consummation of the transactions contemplated by the Stock Purchase Agreement from September 17, 2014 to October 31, 2014.

The effectiveness of the amendment is contingent on (i) the funding into escrow of existing financing commitments of Huntsman, (ii) Huntsman’s obtaining an extension of existing financing commitments from September 17, 2014 to October 31, 2014 or (iii) Huntsman’s securing financing by some other method whereby financing is made available on terms and conditions substantially no less favorable in the aggregate to Huntsman than as set forth in existing financing commitments.

The foregoing description of the Stock Purchase Agreement and the transactions contemplated thereby is not complete and is subject to and qualified in its entirety by reference to the Stock Purchase Agreement, a copy of which is filed as Exhibit 10.1 to the Current Report on Form 8-K of the Company filed on September 23, 2013, and the terms of which are incorporated herein by reference.
