Explanation of Responses:

Id	Content
F1	Shares withheld from the quarterly vesting of annual restricted stock unit awards related to the tax withholding obligation.
F2	On August 26, 2022, the Issuer effected a 1-for-25 reverse stock split of its Common Stock (the "Reverse Stock Split"), resulting in a decrease in the Reporting Person's ownership by 183,320 shares.
F3	The Reverse Stock Split resulted in a decrease in the Reporting Person's ownership by 253 shares.
F4	This option has been adjusted to reflect the Reverse Stock Split (in prior reports, this option was previously reported as covering a number of shares equal to this reported amount times 25 (and at an exercise price equal to this reported exercise price divided by 25)).
F5	Award will vest 50% on July 1, 2023, and the remaining 50% will vest on July 1, 2024.
F6	Award of an employee stock option in connection with a retention agreement. The option vests one-third on May 1, 2022 and two-thirds on May 1, 2023, subject to employee's continued service through the vesting date. Vesting would be accelerated upon a termination of employee's employment without cause.
F7	One-fourth of the option vests on the one-year anniversary date of the grant and the remainder vests in equal quarterly installments over the following three years.
