        <footnote id="F1">On January 2, 2007, the Issuer entered into an agreement with Willing L. Biddle (the &quot;Reporting Person&quot;) whereby the Reporting Person was granted a restricted stock award of 60,000 shares of Common Stock pursuant to the Issuer's Amended and Restated Restricted Stock Award Plan (the &quot;Restricted Stock Award Plan&quot;).</footnote>
        <footnote id="F2">This figure includes 522,500 restricted shares of Common Stock issued pursuant to the Restricted Stock Award Plan.  On January 2, 2007, restrictions applicable to a previously reported grant of 55,000 restricted shares of Common Stock lapsed resulting in the Reporting Person becoming fully vested in such shares.  This resulted in no change in the number of shares beneficially owned by the Reporting Person.</footnote>
