        <footnote id="F1">On July 25, 2025, the Company granted Ms. Reed 150,000 restricted stock units (&quot;RSUs&quot;) under the Company's 2020 Omnibus Incentive Plan. The RSUs granted may vest in four tranches of 37,500 each upon the date the Board determines that the applicable performance condition has been achieved: (i) the common stock of the Company achieves a 10-day volume weighted average price (VWAP) of $6.50; (ii) the common stock achieves a 10-day VWAP of $7.50; (iii) the common stock achieves a 10-day VWAP of $9.50; and (iv) the common stock achieves a 10-day VWAP of $11.50. In the event that the Performance Conditions are not met, the RSUs granted will vest in four equal installments of 37,500 on each of the first, second, third and fourth anniversaries of the grant date, and will be settled upon vesting (or within 30 days thereafter). All vesting events are subject to continued employment on each applicable vesting date.</footnote>
        <footnote id="F2">On July 24, 2026, the first tranche of 37,500 RSUs vested on the first anniversary of the grant date.</footnote>
