Notwithstanding the foregoing, a holder will not have the right to exercise any portion of a pre-funded warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% of the number of common shares outstanding immediately after giving effect to the exercise, which such percentage may be increased or decreased by the holder, but not in excess of 9.99%, upon at least 61 days’ prior notice to the Company. Since the closing of this offering, the Company has issued 505,000 common shares upon the exercise of pre-funded warrants. *OID Note Extension* The Company used a portion of the net proceeds of the public offering to repay $1,250,000 of the 20% OID subordinated promissory notes described in Note 13. Pursuant to a note extension agreement, the maturity date of the remaining notes was extended to the earlier of (i) April 11, 2024 or (ii) the completion of a subsequent financing, in exchange for an additional 20% original issue discount. The Company also subsequently repaid one of the notes in the principal amount of $187,500. Accordingly, the aggregate principal amount of the remaining notes is $2,109,375. *New OID Note* On March 4, 2024, the Company issued a 20% OID subordinated note in the principal amount of $1,250,000 to an accredited investor for a purchase price of $1,000,000.

On April 9, 2024, the note was further amended and restated to increase the principal amount to $2,500,000 and to increase the purchase price to $2,000,000. This note is due and payable on June 4, 2024; provided, however, that if the Company has filed, prior to such date, a registration statement on Form S-1 relating to a public offering of its equity and the Form S-1 is still being reviewed by the SEC as of such date, then the maturity date will be automatically extended until July 5, 2024 and the principal amount of the note shall be increased to $2,750,000. The Company may voluntarily prepay the note in full at any time. In addition, if the Company consummates any equity or equity-linked or debt securities issuance, or enters into a loan agreement or other financing, other than certain excluded debt (as defined in the note), then the Company must prepay the note in full.
