        <footnote id="F2">On May 22, 2000, the reporting person entered into a prepaid forward purchase agreement (the &quot;Agreement&quot;) with an unaffiliated third party (the &quot;Buyer&quot;), under which the reporting person agreed to deliver up to 300,000 shares of Common Stock to the Buyer on May 23, 2003.   The reporting person was paid cash by the Buyer in an amount equal to (300,000 x 67% of the Common Stock share price on May 22, 2000), as specified in the Agreement.  The reporting person pledged 300,000 shares of Common Stock to the Buyer to secure his obligations under the Agreement and retained voting and dividend rights in the pledged shares during the term of the pledge.</footnote>
        <footnote id="F3">The number of shares to be delivered depends on the closing price of the Common Stock on May 21, 2003 (the &quot;Settlement Price&quot;).  If the Settlement Price is less than or equal to $15.54, the reporting person must transfer 300,000 shares to the Buyer.  If the Settlement Price is greater than $15.54 but less than or equal to $26.79, the reporting person must transfer a number of shares equal to (300,000 x $15.54)/Settlement Price.  If the Settlement Price is greater than $26.79, the reporting person must transfer a number of shares equal to 300,000 x (($15.54 + Settlement Price - $26.79)/Settlement Price).</footnote>
