        <footnote id="F2">Each Performance-based Restricted Stock Unit (PSU) represents a contingent right to receive one share of common stock of the Company. Subject to the terms of the PSU Agreement, the PSUs are contingent on satisfying both a performance-based and a time-based vesting condition. The performance-based vesting condition is satisfied if the average closing price of the Company's stock reaches $11.50 using a 20-day look-back period, which period may begin no earlier than 151 days following February 8, 2023. The PSUs will time-vest in approximately three equal annual installments, with such first installment time-vesting on February 10, 2024. Both vesting conditions must be met by February 10, 2028 or else the PSUs will be forfeited.</footnote>
