        <footnote id="F1">The original Form 4 reported a sale of 2,105 shares, which represented the number of shares the reporting person had directed his broker to sell. In fact, due to an error in the broker's systems, the broker confirmed the sale of 2,105 but only 2,042 shares were sold, resulting in an overstatement of the number of shares sold by 63 shares.</footnote>
        <footnote id="F2">Total number of shares directly owned following all transactions reported in the original Form 4 filing.</footnote>
