Ownership

 

(a)

Amount beneficially owned:

 

The Reporting Persons hold 349,997 warrants, exercisable for an aggregate of 174,999 shares of Common Stock (the “2022 Warrants”). Each 2022 Warrant is exercisable for ½ a share of Common Stock. The 2022 Warrants are only exercisable to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would not beneficially own more than 9.99% of the outstanding Common Stock after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the 2022 Warrant (the “2022 Beneficial Ownership Limitation”). As of the date hereof, the 2022 Beneficial Ownership Limitation, limits the exercise of the 2022 Warrants by the Reporting Persons to zero out of the 174,999 shares of Common Stock underlying the 2022 Warrants.

 

The Reporting Persons hold 1,600,000 warrants, exercisable for an aggregate of 1,200,000 shares of Common Stock (the “2023 Warrants” and together with the 2022 Warrants, the “Warrants”). Each 2023 Warrant is exercisable for ¾ a share of Common Stock. The 2023 Warrants are only exercisable to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would not beneficially own more than 9.99% of the outstanding Common Stock after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the 2023 Warrant (the “2023 Beneficial Ownership Limitation”). As of the date hereof, the 2023 Beneficial Ownership Limitation, limits the exercise of the 2023 Warrants by the Reporting Persons to zero out of the 1,200,000 shares of Common Stock underlying the 2023 Warrants.

 

As of the close of business on April 15, 2021 (i) BVF beneficially owned 2,017,290 shares of Common Stock, excluding 81,457 shares of Common Stock issuable upon the exercise of certain 2022 Warrants and 627,431 shares of Common Stock issuable upon the exercise of certain 2023 Warrants, (ii) BVF2 beneficially owned 1,626,270 shares of Common Stock, excluding 52,475 shares of Common Stock issuable upon the exercise of certain 2022 Warrants and 468,740 shares of Common Stock issuable upon the exercise of certain 2023 Warrants, and (iii) Trading Fund OS beneficially owned 257,664 shares of Common Stock, excluding 14,595 shares of Common Stock issuable upon the exercise of certain 2022 Warrants and 81,341 shares of Common Stock issuable upon the exercise of certain 2023 Warrants.

 

BVF GP, as the general partner of BVF, may be deemed to beneficially own the 2,017,290 shares of Common Stock beneficially owned by BVF.

 

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own the 1,626,270 shares of Common Stock beneficially owned by BVF2.

 

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 257,664 shares of Common Stock beneficially owned by Trading Fund OS.

 

BVF GPH, as the sole member of each of BVF GP and BVF2 GP, may be deemed to beneficially own the 3,643,560 shares of Common Stock beneficially owned in the aggregate by BVF and BVF2.

 

Partners, as the general partner of BVF, BVF2, the investment manager of Trading Fund OS, and the sole member of Partners OS, may be deemed to beneficially own the 3,972,300 shares of Common Stock beneficially owned in the aggregate by BVF, BVF2, Trading Fund OS, and certain Partners managed accounts (the “Partners Managed Accounts”), including 71,076 shares of Common Stock held in the Partners Managed Accounts (which excludes 26,472 shares of Common Stock issuable upon the exercise of certain 2022 Warrants and 22,490 shares of Common Stock issuable upon the exercise of certain 2023 Warrants).

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 3,972,300 shares of Common Stock beneficially owned by Partners.

 

Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 3,972,300 shares of Common Stock beneficially owned by BVF Inc.

 

The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of any shares of Common Stock owned by another Reporting Person. BVF GP disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF. BVF2 GP disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF2. Partners OS disclaims beneficial ownership of the shares of Common Stock beneficially owned by Trading Fund OS.
