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.
