12/27/2005 Proxy Information

Until his retirement from the firm in March 2003, Mr. Gordon was Vice Chairman, Investment Banking, for Merrill Lynch & Co., which firm has provided various types of investment banking services to the Company, including serving as an underwriter on our public debt and equity offerings and providing advice in connection with merger and acquisition transactions. Mr. Ware is the president and a shareholder of Amarillo National Bank, Amarillo, Texas, which bank provides an $18 million short-term line of credit to the Company, serves as a depository bank for the Company and is trustee for the Company’s 1998 Long-Term Incentive Plan. The Company pays fees to Amarillo National Bank, which are normal and customary for these types of services.

All non-management members of the Board of Directors, other than Mr. Springer, satisfy the independence requirements of the New York Stock Exchange. Because Mr. Springer’s son-in-law is employed as an auditor with Ernst & Young LLP, the Company’s independent registered public accounting firm, under the corporate governance-related listing standards of the New York Stock Exchange, Mr. Springer may not be considered independent from the Company. Mr. Springer’s son-in-law is not involved in the audit of the Company and is not considered a “covered person” with respect to the Company, as defined under the SEC’s independence-related regulations for auditors. Thus, this relationship has no effect on Ernst & Young LLP’s independence as our auditors. In addition, Mr. Springer does not serve on our Audit Committee. The Board of Directors has also adopted categorical standards of director independence, which are attached as Exhibit A to this Proxy Statement, which standards supplement the independence requirements by the New York Stock Exchange. Directors who meet these standards are considered to be “independent.” Note that for purposes of the standards, the Board has adopted the definition of an “immediate family member”, as set forth by the New York Stock Exchange, which includes parents, siblings and in-laws of the director, as well as anyone else (other than domestic employees) who shares such director’s home. The Board has determined that Messrs. Gordon and Ware, as well as all other current non-management directors other than Mr. Springer, as discussed above, meet these standards and are, therefore, considered to be independent directors because none of their relationships with the Company have been determined to be material.
