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>
