On November 14, 2014, Rockwood Holdings, Inc. (the “Company”) held a special meeting of its stockholders in connection with the Agreement and Plan of Merger, dated as of July 15, 2014, among Albemarle Corporation (“Albemarle”), Albemarle Holdings Corporation, a wholly-owned subsidiary of Albemarle (“Merger Sub”) and the Company, pursuant to which Merger Sub will merge with and into the Company, with the Company surviving as a wholly owned subsidiary of Albemarle.

At the special meeting, the following proposals were submitted to a vote of the Company’s stockholders. each of which is described in detail in the definitive proxy statement filed by the Company with the Securities and Exchange Commission on October 1, 2014.  For each of the following proposals, a quorum was present for the purpose of the vote, and a summary of the voting results for each proposal is as follows:

Proposal 1: Adopt the Agreement and Plan of Merger, dated as of July 15, 2014, among Albemarle Corporation, Albemarle Holdings Corporation and Rockwood Holdings, Inc., as it may be amended from time to time.

Proposal 1 was approved by the Company’s stockholders, as the number of votes in favor of Proposal 1 constituted a majority of the outstanding shares of the Company’s common stock entitled to vote on such proposal.
