        <footnote id="F1">The Restricted Stock Units (RSU), the conversion of which are reported herein, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on February 18, 2005.  On that date the fair market value (FMV) of a share of the issuer's stock was $24.90.  The RSU grant vests in equal portions over a three (3) year period, and are received by the Reporting Person upon vesting, on a one-for-one basis unless the Reporting Person has previously chosen a longer deferral period.  This report reflects the vesting of the final third of RSU from the original grant and the acquisition by the Reporting Person of the underlying shares minus sufficient shares withheld by the issuer at the request of the Reporting Person as necessary to pay applicable income taxes.  The FMV of the shares, based on the closing price of the issuer's stock on February 15, 2008 (last business day before shares vested) is $43.11.</footnote>
