Explanation of Responses:

( 1 )These shares of Series A Non-Voting Convertible Preferred Stock ("Preferred Stock") were issued to the Reporting Person under securities purchase agreements entered into with the Issuer, pursuant to which the Issuer has agreed to submit to its stockholders the approval of the conversion of the Preferred Stock into shares of Common Stock at its 2024 annual meeting of stockholders (the "Conversion Proposal"). Following such approval of the Conversion Proposal, each share of Preferred Stock will automatically convert into 40 shares of Common Stock, subject to certain limitations, including that the Reporting Person is prohibited from converting shares of Preferred Stock into shares of Common Stock if, as a result of such conversion, the Reporting Person, together with his affiliates, would beneficially own more than 19.9% of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion. The Preferred Stock has no expiration date.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
