        <footnote id="F1">Represents the number of shares required to be sold by the reporting person to cover tax withholding obligations in connection with the vesting of certain restricted stock units (&quot;RSUs&quot;) previously reported in Table I following the date of grant. This sale is mandated by the Issuer's election under its 2005 Long Term Incentive Compensation Plan (as amended) to require the satisfaction of tax withholding obligations to be funded by a &quot;sell to cover&quot; transaction and does not represent a discretionary trade by the reporting person.</footnote>
        <footnote id="F2">This number includes unvested RSUs previously reported.</footnote>
