        <footnote id="F1">The restricted stock award reported on this Form 4 will lapse in five equal annual installments beginning on March 4, 2027 and ending on March 4, 2031.</footnote>
        <footnote id="F2">Each Performance Restricted Stock Unit (each, a &quot;PRSU&quot;) represents a contingent right to receive, at vesting, one share of Common Stock subject to the achievement of certain performance goals and service-based vesting requirements.</footnote>
        <footnote id="F3">These PRSUs consist of five equal tranches, each of which will be earned if and when the closing price of one share of Common Stock equals or exceeds the specified stock price performance goal for such tranche for 60 consecutive trading days during the three year performance period beginning on the grant date, provided that any earned PRSUs will not be settled until the third anniversary of the grant date, subject to satisfaction of the service-based vesting requirements set forth in the award agreement. The specified stock price performance goals for each tranche are $7.67, $8.52, $9.38, $10.23 and $11.08, respectively.</footnote>
