        <footnote id="F1">Shares withheld to cover taxes upon vesting of restricted stock units. No shares were sold.</footnote>
        <footnote id="F2">This amendment is being filed to correct an administrative error which resulted in the amount of shares withheld for the payment of taxes due upon vesting of the Restricted Stock Units (RSUs) being misreported. The number of shares beneficially owned following this transaction were therefore also misreported and accordingly have been updated in this amendment. The number of RSUs that vested remains unchanged from the filing of the original Form 4.</footnote>
