The Series H Warrant is currently exercisable at a price of $12.075 per share (subject to adjustment as provided in the Series H Warrant), subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of the Series H Warrant to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock, and expires on June 5, 2025. The 2022 Warrant is currently exercisable at a price of $1.96 per share (subject to adjustment as provided in the 2022 Warrant), subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of the 2022 Warrant to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock, and expires October 25, 2027.

As of December 31, 2023, LPC Fund owned 9.676% of the outstanding shares of Common Stock.

In each case representing the approximate maximum number of shares (in addition to the 86,905 outstanding shares of Common Stock referred to in the prior sentence) that may be acquired by LPC Fund upon exercise of such warrant without exceeding the 9.99% beneficial ownership limitation contained in such warrant. The Reporting Persons may be deemed to beneficially own an aggregate of 1,307,049 shares of Common Stock (as calculated pursuant to Section 13(d) of the Act, and Rule 13d-3 promulgated thereunder), representing 9.676% of the outstanding shares of Common Stock (based on such information regarding the outstanding shares of Common Stock supplied by the Issuer to LPC Fund).

As of February 9, 2024, LPC Fund owned 2.709% of the outstanding shares of Common Stock. Based on the information provided by the Issuer in its Current Report on Form 8-K, filed with the Securities Exchange Commission on February 2, 2024, there was a total of 30,452,042 shares of Common Stock outstanding as of January 31, 2024, which includes the 10,078 shares of Common Stock previously issued to LPC Fund. Pursuant to Rule 13d-3(d)(1)(i) under the Act, the denominator used in the calculation for the percentage of class owned by the Reporting Persons, assumes the issuance 10,407 shares of Common Stock underlying the Series D Warrant, 19,820 shares of Common Stock underlying the Series F Warrant, 20,180 shares of Common Stock underlying the Series G Warrant, 54,348 shares of Common Stock underlying the Series H Warrant, 586,294 shares of Common Stock underlying the 2022 Warrant, and 146,520 shares of Common Stock underlying the Preferred Series E-4 Warrant. In each case representing the approximate maximum number of shares (in addition to the 10,078 outstanding shares of Common Stock referred to in the prior sentence) that may be acquired by LPC Fund upon exercise of such warrant without exceeding the 9.99% beneficial ownership limitation contained in such warrant. The Reporting Persons may be deemed to beneficially own an aggregate of 847,647 shares of Common Stock (as calculated pursuant to Section 13(d) of the Act, and Rule 13d-3 promulgated thereunder), representing 2.709% of the outstanding shares of Common Stock (based on such information regarding the outstanding shares of Common Stock supplied by the Issuer to LPC Fund). The updated disclosure as of February 9, 2024 is included solely to reflect the beneficial ownership by the Reporting Persons of less than 5% of the outstanding shares of Common Stock and cessation of further reporting thereby on Schedule 13G.

Page 11 of 13

In the case of each of the Warrants, the warrant amounts are in addition to the 86,905 outstanding shares of Common Stock issued to LPC Fund and referred to in clause (i) above and are subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of any Warrants to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock.

As of February 9, 2024, LPC Fund beneficially owned, directly the following securities from the Issuer: (i) 10,078 shares of Common Stock purchased by LPC Fund directly from the Issuer; (ii) 146,520 shares of Common Stock underlying the Preferred Series E-4 Warrant; (iii) 10,407 shares of Common Stock underlying the Series D Warrant; (iv) 19,820 shares of Common Stock underlying the Series F Warrant; (v) 20,180 shares of Common Stock underlying the Series G Warrant; (vi) 54,348 shares of Common Stock underlying the Series H Warrant; and (vii) 586,294 shares of Common Stock underlying the 2022 Warrant. In the case of each of the Warrants, the warrant amounts are in addition to the 10,078 outstanding shares of Common Stock issued to LPC Fund and referred to in clause (i) above and are subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of any Warrants to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock.

The Series D Warrant, Series F Warrant, Series G Warrant, Series H Warrant and 2022 Warrant each include a customary “cashless” exercise provision, which may be used to acquire underlying shares of Common Stock if at the time of exercise an effective registration statement registering the resale of such shares under the Act is not available to the warrant holders.

LPC is the Managing Member of LPC Fund. RCC and Alex Noah are the Managing Members of LPC. Mr. Scheinfeld is the president and sole shareholder of RCC, as well as a principal of LPC. Mr. Cope is the president and sole shareholder of Alex Noah, as well as a principal of LPC. As a result of the foregoing, Mr. Scheinfeld and Mr. Cope have shared voting and shared investment power over the shares of Common Stock of the Issuer held directly by LPC Fund.

Pursuant to Section 13(d) of the Act and the rules thereunder, each of LPC, RCC, Mr. Scheinfeld, Alex Noah, and Mr. Cope may be deemed to be a beneficial owner of the shares of Common Stock of the Issuer beneficially owned directly by LPC Fund.

The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of any shares of Common Stock owned by another Reporting Person. Pursuant to Rule 13d-4 of the Act, each of LPC, RCC, Mr. Scheinfeld, Alex Noah, and Mr. Cope disclaims beneficial ownership of the shares of Common Stock of the Issuer held directly by LPC Fund.
