        <footnote id="F1">Represents shares of restricted stock previously issued to the Reporting Person in accordance with Rule 16b-3 and withheld by the Issuer on March 9, 2009 in order to satisfy the Reporting Person's tax liability incurred upon the vesting of shares of restricted stock as permitted under the Issuer's 2006 Omnibus Incentive Compensation Plan.</footnote>
        <footnote id="F2">Any Form 4 filed by the Reporting Person after March 9, 2009, and before August 23, 2011, did not take into account the transaction reported in this Form 4 and therefore included an additional 6,505 shares in the amount of securities beneficially owned by the Reporting Person following the reported transaction. The accurate amount of securities beneficially owned by the Reporting Person as of the date of this filing is reflected in the Reporting Person's Form 4 filed with the Commission on August 23, 2011, which takes into account the transaction reported in this Form 4.</footnote>
