        <footnote id="F1">Represents the number of shares of the Issuer's common stock (&quot;Common Stock&quot;) underlying restricted stock units (&quot;RSUs&quot;). Each RSU represents the contingent right to receive one share of Common Stock upon settlement. 25% of the RSUs vested and settled into Common Stock on September 21, 2023, and 25% of the RSUs vest and settle into Common Stock in equal quarterly installments thereafter, subject to the Reporting Person's Continuous Service (as defined in the Issuer's 2022 Equity Incentive Plan) through each such date.</footnote>
