        <footnote id="F1">On August 2, 2002,  319,177 shares beneficially owned by the Reporting Person were sold at a price of $19.00 per share.  The transaction was reported on Schedule 13D and on Form 4s filed by other reporting persons, but the Reporting Person did not timely file its Form 4 with respect to this transaction.  The 1,024,669 shares reflected in Column 5 as beneficially owned are the number of shares so owned after giving effect to this 2002 transaction and before the February 2004 transaction reported in the second row.</footnote>
        <footnote id="F2">The Reporting Person is the general partner of Aurora Overseas Capital Partners L.P., which in turn is the general partner of Aurora Overseas Equity Partners I, L.P., the partnership that owns the reported securities.</footnote>
