        <footnote id="F1">Represents shares of the Issuer's common stock underlying restricted stock units (&quot;RSUs&quot;) awarded to the Reporting Person. The RSUs will vest in a series of four successive equal annual installments upon the Reporting Person's continuation in Board service with the Issuer through January 21, 2015, with the first installment to vest on February 21, 2012 and the remaining installments to vest on the second, third and fourth anniversaries of the January 21, 2011 award date, subject to accelerated vesting upon certain changes in ownership or control of the Issuer.</footnote>
        <footnote id="F2">Unless the Reporting Person elects to defer the issuance of the shares until the Reporting Person's separation of service from the Issuer, the shares of the Issuer's common stock will be issued as the RSU's vest.</footnote>
