1 This percentage is calculated based upon 10,099,591 shares of the Issuer’s common stock outstanding as of November 10, 2022 in accordance with Issuer’s prospectus supplement filed on November 10, 2022. However, as more fully described in Item 3, the securities reported in rows (8), (10) and (11) show the number of shares of Common Stock that would be issuable upon full conversion and exercise of such reported securities and do not give effect to such blockers. Therefore, the actual number of shares of Common Stock beneficially owned by such Reporting Person, after giving effect to such blockers, is less than the number of securities reported in rows (8), (10) and (11).
