Item 1.01 Entry into a Material Definitive Agreement.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

Mr. Gibbons, 53, was most recently Senior Vice President and Chief Financial Officer of Westlake Chemical Corporation, a worldwide commodity chemical company traded on the NYSE. Prior to joining Westlake, Mr. Gibbons was with Valero Energy Corporation, beginning his career there in 1981, holding positions of increasing responsibility, ending as Executive Vice President and Chief Financial Officer from January 1998 through the end of 2003. Prior to joining Valero, Mr. Gibbons spent five years working in the Houston office of Deloitte & Touche, where his practice was concentrated in the energy industry. He is a member of the Financial Executives Institute, American Institute of Certified Public Accountants and the Texas Society and Houston chapter of Certified Public Accountants. He earned a B.B.A. in accounting from the University of Texas at Austin in December 1975.

Effective February 26, 2007, Mr. Gibbons entered into an employment agreement with the Company. Pursuant to the terms of the employment agreement, Mr. Gibbons serves as the Senior Vice President and Chief Financial Officer, and in such other positions as the parties may mutually agree, for an initial period of three years, subject to the terms of the employment agreement. The employment agreement provides for a base salary of $350,000 per year. For a full description of the employment arrangement with Mr. Gibbons, please refer to the employment agreement, a copy of which has been filed herewith as Exhibit 10.1.

Effective February 26, 2007, the Company also entered into an Indemnification and Hold Harmless Agreement with Mr. Gibbons, which provides that if Mr. Gibbons is a party or is threatened to be made a party to any action, the Company will indemnify him and hold him harmless against any and all liabilities or losses incurred in connection with such action if it arises out of or is related to the fact that he is or was serving as an officer of the Company, to the fullest extent permitted by then applicable law. Further, the rights of Mr. Gibbons under this agreement are in addition to any other rights he may have under the Company’s corporate governance documents or applicable law. The terms and conditions of Mr. Gibbons’ Indemnification and Hold Harmless Agreement are virtually identical to the terms and conditions in similar contracts pursuant to which the Company has agreed to indemnify its directors and its executive officers. A copy of the Indemnification and Hold Harmless Agreement has been filed herewith as Exhibit 10.2.
