        <footnote id="F1">Each performance share represents a contingent right to receive one share of Company Common Stock.</footnote>
        <footnote id="F2">At the Company's 2003 annual meeting in May 2003, the Company's shareholders awarded Mr. Culp the right to receive 388,600 shares of Company Common Stock, subject to specified conditions.  As further described in the Company's 2003 proxy statement, the  Company will grant Mr. Culp 388,600 shares of Company Common Stock on January 2, 2010 if (1) Mr. Culp remains employed as CEO of the Company on December 1, 2009,  (2) the Company achieves certain specified financial targets, and (3) the Company's Compensation Committee has certified that such financial targets have been attained.  On May 4, 2004, the Compensation Committee certified that these financial targets have been attained.  As a result, if Mr. Culp remains employed as CEO on December 1, 2009, the Company will grant him 388,600 shares of Company Common Stock on January 2, 2010.  This Form 4 is being filed in connection with the Compensation Committee's determination that the performance criteria of the award have been achieved.</footnote>
