        <footnote id="F1">This transaction was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person.  On July 12, 2005, 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 will have to deliver up to the 37,982  shares of the Issuer's common stock referenced in column 7 of Table II to the securities brokerage firm on July 12, 2007.  The number of shares the reporting person will be required to deliver on such date shall be a function of the closing price of the Issuer's common stock on such date.  Similarly, the amounts that would be in columns 2 and 8 of Table II will be a function of, among other things, the closing price of the Issuer's common stock on July 12, 2007.</footnote>
        <footnote id="F2">The derivative security is a prepaid variable forward contract as referenced in footnote (1).  $0.00 has been inserted to satisfy the requirements to submit this form via the EDGAR system.</footnote>
        <footnote id="F3">The original Form 4 filed by the reporting person inadvertently stated the ownership form in Column 10 of Table II to be Direct.  This amended form relects the correct ownership form in Column 10 of Table II to be Indirect and reflects the nature of indirect beneficial ownership in Column 11 of Table II to be the McGee Revocable Tr.</footnote>
