        <footnote id="F1">The shares acquired represent a grant of restricted stock to the reporting person.  The grant will vest in thirds annually beginning on June 14, 2005 and ending on June 14, 2007.</footnote>
        <footnote id="F2">On June 15, 2004, the Reporting Person filed a Form 4 which reported his receipt of a grant of 5,010 shares of restricted stock.  The amount of securities directly beneficially owned following this reported transaction was incorrectly reported as 47,510.  This Form 4/A amends Table I to disclose the amount of securities of beneficially owned following the grant of 5,010 shares of restricted stock to be 31,676 with the remaining 13,334 shares indirectly owned as reported above.</footnote>
