### Footnotes:

(1) Reflects a grant of restricted stock units, which vested in full upon grant, pursuant to the Issuers 2021 Stock Incentive Plan made to the Reporting Person in exchange for the Reporting Persons agreement with the Issuer to forego his cash bonus earned for the second quarter of 2022, as determined by the Issuer's board of directors annually after the end of 2022. The number of restricted stock units was determined by dividing the amount of such cash bonus earned for the second quarter of 2022 by the thirty (30) day volume weighted average price (VWAP) of the Issuers common stock as of the same date used to determine other employee stock based bonuses paid in respect of the second quarter of 2022.

(2) Reflects a grant of restricted stock units, which vested in full upon grant, pursuant to the Issuers 2021 Stock Incentive Plan made to the Reporting Person in exchange for the Reporting Persons agreement with the Issuer to forego his cash bonus earned for the third quarter of 2022, as determined by the Issuer's board of directors annually after the end of 2022. The number of restricted stock units was determined by dividing the amount of such cash bonus earned for the third quarter of 2022 by the thirty (30) day volume weighted average price (VWAP) of the Issuers common stock as of the same date used to determine other employee stock based bonuses paid in respect of the third quarter of 2022.

The number of restricted stock units was determined by dividing the amount of such cash bonus earned for the fourth quarter of 2022 by the thirty (30) day volume weighted average price (VWAP) of the Issuers common stock as of the same date used to determine other employee stock based bonuses paid in respect of the fourth quarter of 2022.

(4) Represents a weighted average sales price per share for these shares, which were sold in multiple transactions at prices ranging from $2.90 to $2.94. The Reporting Person has provided to the Issuer, and undertakes to provide to the staff of the Commission or any security holder of the Issuer, upon request, full information regarding the number of shares sold at each separate price within the range. The shares were sold in order to satisfy tax obligations payable upon the settlement of the restricted stock units previously granted to the Reporting Person in exchange for the Reporting Person's agreement with the Issuer to forego his cash bonus earned in respect of the second quarter of 2022, the third quarter of 2022 and the fourth quarter of 2022.
