Each PRSU represents a contingent right to receive one share of Registrant common stock upon vesting and settlement.</footnote>
        <footnote id="F2">Represents shares withheld to satisfy tax withholding obligations arising as a result of the vesting and settlement of the PRSUs described in footnote 1.</footnote>
