The A-1 Warrants are exercisable for a period of five years following the date of issuance and have an exercise price of $1.08 per share. The A-1 Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “A-1 Warrants Blocker”). As of the close of business on December 31, 2021, the A-1 Warrants Blocker limits the aggregate exercise of A-1 Warrants by the Reporting Persons to 2,592,572 out of the 2,592,572 shares of Common Stock underlying the A-1 Warrants owned by the Reporting Persons in the aggregate.

The A-2 Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Exchange Act, more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “A-2 Warrants Blocker”). As of the close of business on December 31, 2021, the A-2 Warrants Blocker limits the aggregate exercise of A-2 Warrants by the Reporting Persons to 6,306,280 out of the 6,306,280 shares of Common Stock underlying the A-2 Warrants owned by the Reporting Persons in the aggregate.

The Reporting Persons hold 2,532,155 A-3 Warrants (the “A-3 Warrants”) exercisable for an aggregate of 2,532,155 shares of Common Stock. The A-3 Warrants are exercisable for a period of five years following the date of issuance and have an exercise price of $0.7464 per share. The A-3 Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Exchange Act, more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “A-3 Warrants Blocker”). As of the close of business on December 31, 2021, the A-3 Warrants Blocker limits the aggregate exercise of A-3 Warrants by the Reporting Persons to 762,383 out of the 2,532,155 shares of Common Stock underlying the A-3 Warrants owned by the Reporting Persons in the aggregate. In providing beneficial ownership described herein, the Reporting Persons have assumed that the A-3 Warrants held by BVF to acquire 762,383 shares of Common Stock would be exercised, which would bring the Reporting Persons to the aggregate 9.99% limitation, and the remaining A-3 Warrants exercisable into 600,367 shares of Common Stock owned by BVF, A-3 Warrants exercisable into 957,489 shares of Common Stock owned by BVF2, A-3 Warrants exercisable into 152,442 shares of Common Stock owned by Trading Fund OS and the A-3 Warrants exercisable into 59,474 shares of Common Stock held in the Partners Managed Account, would not be exercised due to the A-3 Warrants Blocker.
