        <footnote id="F1">The reporting person has elected to receive restricted stock units in lieu of cash retainer fees payable for service on the Issuer's board of directors and any committees thereof. Each restricted stock unit represents a contingent right to receive, following vesting, one share of the Issuer's common stock.  The number of restricted stock units issued represents the quotient of (A) the amount of such fees divided by (B) the Issuer's closing stock price on the grant date, rounded down to the nearest whole share.  All restricted stock units will vest on December 31, 2023 subject to the non-employee director continuing to be a service provider through the applicable vesting date.</footnote>
