Explanation of Responses:

1. Restricted stock units ("RSUs") convert into common stock on a one-for-one basis.

2. The RSUs shall vest upon the earlier of (i) the one-year anniversary of the date of grant or (ii) the day prior to the Issuer's next annual shareholder meeting following the date of grant.

3. Mr. Johnson is deemed to hold the securities reported herein for the benefit of certain affiliated funds (the "Caligan Funds") to which Caligan Partners LP ("Caligan") serves as investment manager and a managed account to which Caligan serves as a consultant, and may, after vesting, if applicable, transfer the securities directly to such Caligan Funds or managed account.

4. Since the filing of the Form 4 filed by the Reporting Persons on September 7, 2022, and more than 6 months ago, the managed account to which Caligan serves as a consultant has reduced its holding by 480,000 shares of Common Stock, and accordingly, such shares of Common Stock are no longer included in the total amount of securities beneficially owned that are reported in Column 5.

5. Securities held by (i) Caligan Partners Master Fund LP, a Cayman Islands limited partnership, (ii) an affiliated fund to which Caligan serves as investment manager, (iii) managed accounts to which Caligan serves as investment manager, and (iv) a managed account to which Caligan serves as a consultant. Mr. Johnson is the Managing Partner of Caligan and a Managing Member of Caligan Partners GP LLC, the general partner of Caligan.

Remarks:

Each Reporting Person disclaims beneficial ownership in the securities reported on this Form 4 except to the extent of its or his pecuniary interest, if any, therein, and this report shall not be deemed to be an admission that such Reporting Person is the beneficial owner of such securities for purposes of Section 16 or for any other purpose. Caligan may be deemed to be a director by deputization of the Issuer by virtue of the fact that Mr. Johnson currently serves on the Issuer's board of directors.
