        <footnote id="F1">Represents 46 shares of Common Stock of the issuer withheld by the issuer in satisfaction of the applicable withholding taxes on certain shares of Common Stock that became issuable on December 29, 2009 pursuant to the terms of the December 29, 2006 Restricted Stock Unit Issuance Agreement between the reporting person and the issuer (the &quot;Agreement&quot;). The issuable shares were previously reported as Table I securities at the time the restricted stock units were granted, and accordingly the issuance of those shares is not a reportable transaction on this Form 4.</footnote>
        <footnote id="F2">Includes 83 shares of Common Stock of the issuer issued to the reporting person on December 29, 2009 under the Agreement, 2,237 shares of Common Stock of the issuer, and 5,508 shares of Common Stock of the issuer held under an IRA account.  Also includes 2,940 shares underlying restricted stock units.</footnote>
