Item 3. Source and Amount of Funds or Other Consideration

Prior to the Issuer’s initial public offering (the “IPO”), and after accounting for the 8.4-1 reverse stock split that the Issuer had effected on July 13, 2021, FH-VII and FH-VIIA collectively purchased from the Issuer in a series of private transactions, 1,541,822 shares of Series A Preferred Shares (“Series A Stock”), 951,742 shares of Series B Preferred Shares (“Series B Stock”) and 290,210 shares of Series C Preferred Shares (“Series C Stock”) for an aggregate purchase price of $19,371,856. Upon closing of the IPO, the shares of Series A Stock, Series B Stock and Series C Stock held by FH-VII and FH-VIIA automatically converted into shares of Common Stock of the Issuer on a 1-to-1 basis, resulting in FH-VII and FH-VIIA collectively holding a total of 2,783,774 shares of Common Stock at such time. In addition, at the time of the IPO, FH-VII and FH-VIIA collectively purchased an aggregate of 187,500 shares of Common Stock of the Issuer at the IPO price of $16.00 per share.

Between November 9, 2022 and November 11, 2022, FLSPF purchased an aggregate of 376,098 shares of Common Stock of the Issuer for a total approximate purchase price of $6,406,706.

Between November 9, 2022 and November 11, 2022, FLSPOF purchased an aggregate of 376,097 shares of Common Stock of the Issuer for a total approximate purchase price of $6,406,689.

Between November 9, 2022 and November 11, 2022, FLS XI purchased an aggregate of 178,738 shares of Common Stock of the Issuer for a total approximate purchase price of $3,044,744.

FH-VII holds 2,312,331 shares of Common Stock of the Issuer as of the date of this filing (the “FH-VII Shares”), FH-VIIA holds 658,943 shares of Common Stock of the Issuer as of the date of this filing (the “FH-VIIA”), FLSPF holds 376,098 shares of Common Stock of the Issuer as of the date of this filing (the “FLSPF Shares”), FLSPOF holds 376,097 shares of Common Stock of the Issuer as of the date of this filing (the “FLSPOF Shares”) and FLS XI holds 178,738 shares of Common Stock of the Issuer as of the date of this filing (the “FLS XI Shares”).

The working capita l of FH-VII, FH-VIIA, FLSPF, FLSPOF and FLS XI was the source of the funds for the purchase of the FH-VII Shares, the FH-VIIA Shares, the FLSPF Shares, the FLSPOF Shares and the FLS XI Shares. No part of the purchase price of the FH-VII Shares, the FH-VIIA Shares, the FLSPF Shares, the FLSPOF Shares or the FLS XI Shares was represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the FH-VII Shares, the FH-VIIA Shares, the FLSPF Shares, the FLSPOF Shares and the FLS XI Shares.
