The description of the Merger and the Merger Agreement contained in this Item 2.01 does not purport to be complete and is subject to and qualified in its entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission (the “SEC”) on July 18, 2014, and is incorporated by reference herein.  The information set forth in Items 5.01 and 5.02 of this Current Report on Form 8-K is incorporated by reference herein.

In connection with the consummation of the Merger, Albemarle and the Company notified the New York Stock Exchange (the “NYSE”) that each issued and outstanding share of Company Common Stock (other than the Excluded Shares (excluding shares held by any wholly-owned subsidiaries of the Company)) was canceled and that each outstanding share of Company Common Stock (other than the Excluded Shares) was converted into the right to receive the Merger Consideration.  As a result, all shares of Company Common Stock were removed from trading on the NYSE following the close of trading on January 12, 2015.  Accordingly, the Company requested on January 12, 2015 that the NYSE file with the SEC a notification of removal from listing and registration on Form 25 to effect the delisting of the shares of Company Common Stock from the NYSE and the deregistration of the shares of Company Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  Additionally, the Company intends to file a Form 15 with the SEC requesting the termination of registration of the shares of Company Common Stock under Section 12(g) of the Exchange Act and the suspension of reporting obligations under Sections 13 and 15(d) of the Exchange Act.  The information set forth in Item 2.01 is incorporated by reference into this Item 3.01.
