        <footnote id="F1">On November 8, 2021, the reporting person was granted an option to purchase 1,029,167 ordinary shares of the Issuer. 29,167 of the ordinary shares underlying the option will be eligible to vest based on: (i) the achievement of certain performance criteria for the fiscal year ended December 31, 2021; and (ii) the reporting person remaining in continuous service through the first anniversary of the grant date. The remaining 1,000,000 of the ordinary shares underlying the option will be eligible to vest in five equal annual installments based on the Issuer's satisfaction of certain performance criteria for each of the fiscal years ending December 31, 2022, 2023, 2024, 2025, and 2026. On March 30, 2022, the compensation committee certified that the Issuer had achieved the performance criteria for 2021. As a result, the 29,167 ordinary shares underlying the option are now eligible to vest based solely on the satisfaction of the continuous service requirement.</footnote>
