Explanation of Responses:

Id	Content
F1	Each restricted stock unit (the "RSU") represents a contingent right to receive one share of the Issuer's Common Stock.
F2	These shares of the Issuer's Common Stock were sold automatically to cover taxes upon the vesting of RSUs.
F3	The price reported in Column 4 is a weighted average price of all shares sold on the transaction date by the Issuer's broker to cover taxes upon the vesting of RSUs for certain employees of the Issuer, including the Reporting Person. These shares were sold in multiple transactions at prices ranging from $9.94 to $10.21, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.
F4	These RSUs vested in a series of sixteen successive quarterly installments measured from February 8, 2022, generally subject to the Reporting Person's continued service with the Issuer, and had no expiration date.
F5	These numbers have been adjusted to reflect the one-for-twenty reverse stock split effective September 15, 2025.
F6	These RSUs vest in a series of four successive equal annual installments measured from February 8, 2023, generally subject to the Reporting Person's continued service with the Issuer, and have no expiration date.
