        <footnote id="F1">On June 25, 2003, the reporting person entered into a prepaid variable forward contract with a securities brokerage firm. Under the terms of the documents relating to such contract, the reporting person had to deliver up to the 250,000 shares of the Issuer's common stock referenced in column 7 of Table II to the securities brokerage firm on June 26, 2006. The number of shares the reporting person had to deliver on such date was a function of the closing price of the Issuer's common stock on such date. The amounts that would be in columns 2 and 8 of Table II were also a function of, among other things, the closing price of the Issuer's common stock on June 26, 2006.  Such prepaid variable forward contract terminated by its terms on 6/26/06 and pursuant to its terms 200,283 shares of the Issuer's common stock were retained by the securities brokerage firm on 6/26/06 and 49,717 were retained by reporting person.</footnote>
        <footnote id="F2">The original Form 4 filed by the reporting person inadvertently reported both the number of derivative securities in Column 5 of Table II and the amount of securites underlying derivative security in Column 7 of Table II as 1.  The amount in Column 7 of Table II should have been 250,000.  No other changes have been made to the original Form 4.</footnote>
        <footnote id="F3">$0.00 has been inserted to satisfy the requirements to submit this form via the EDGAR system.</footnote>
