        <footnote id="F1">On June 29, 2001 James C. Smith entered into a PEACS variable share forward agreement with an unaffiliated third party (the &quot;PEACS program&quot;), whereby Mr. Smith will be obligated to deliver between 1,000,000 and 2,000,000 shares of common stock of the Issuer on dates ranging between January 7, 2002 and June 25, 2003.  The exact number of shares to be delivered and the purchase price per share will depend on the number fo trading days on which the closing price per share of common stock exceeds $25.75.  The PEACS program is a component of a stock sale plan adopted by Mr. Smith on June 20, 2001, which plan is intended to comply with Rule 10b5-1 under the Securities and Exchange Act of 1934 (the &quot;Rule 10b5-1 plan&quot;).  This sale represents the delivery of shares pursuant to settlement under the PEACS program.</footnote>
        <footnote id="F2">Represents shares subject to the PEACS program.</footnote>
        <footnote id="F3">Mr. Smith is also the direct owner of 463,934 shares. In addition 191,348 shares are held by the James C. and Norma I. Smith Foundation.</footnote>
