        <footnote id="F1">The Restricted Stock Units (RSUs), the conversion of which are reported herein, were granted to the reporting person by the issuer as part of the equity incentive grant made by the issuer on January 6, 2004.  On that date, the fair market value of a share of the issuer's stock was $23.80.  The RSUs vest in equal portions over a 3-year period and are received by the reporting person upon vesting unless the reporting person has previously chosen a longer deferral period.  This report reflects the January 11, 2007 issuance by the issuer of shares underlying the final one-third of these RSUs and withholding by the issuer of sufficient shares to pay income taxes required to be withheld from the reporting person.  The fair market value of the shares, based on the closing price of the issuer's stock on the vesting date is $35.22.</footnote>
