| 1 | Represents 1,488,096 shares of Common Stock purchased by LPC Fund directly from the Issuer in a registered direct offering of Common Stock on February 2, 2023 (the "<u>Registered Direct Offering</u>") and a warrant to purchase 1,488,096 shares of Common Stock (the "<u>Warrant</u>") purchased by LPC Fund directly from the Issuer in a concurrent private placement (the "<u>Private Placement</u>"). The Warrant, however, contains a 9.99% contractual cap on the amount of outstanding shares of the Issuer's common stock that LPC Fund may own upon exercise of such Warrant. Therefore, the number of shares of the Issuer's common stock beneficially owned by LPC Fund under the Warrant as of the date of this filing was 12,959 shares, which, when combined with the 1,488,096 shares of Common Stock presently owned, is 9.99% of the 15,025,584 shares that were outstanding on that date (as reported in the Issuer's prospectus supplement filed on February 6, 2023). The shares outstanding includes the 1,488,096 shares of Common Stock of the Issuer owned directly by LPC Fund, but does not include any shares issuable upon exercise of the Warrant issued to LPC Fund or any other investor in the Private Placement. |

---

As of February 2, 2023, LPC Fund beneficially owned, directly, 1,488,096 shares of Common Stock, purchased by LPC Fund directly from the Issuer in the Registered Direct Offering and 12,959 shares currently exercisable under the Warrant purchased directly from the Issuer in the Private Placement. The Warrant amount is 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 to exceed 9.99% of the outstanding Common Stock.

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.
