This Amendment No. 1 is being filed jointly by the Reporting Persons and amends the Schedule 13G initially filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on May 8, 2024 (the “Schedule 13G”).

Except as set forth below, all Items of the Schedule 13G remain unchanged. All capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13G.

Item 2.

(d) Title of Class of Securities

Common Shares, no par value per share, of the Issuer (the “Common Stock”).

Item 4. Ownership.

(a) and (b):

As of the close of business on September 30, 2024, each of the Reporting Persons may have been deemed to have beneficial ownership of 438,220 shares of Common Stock issuable upon exercise of a warrant held by Intracoastal (“Intracoastal Warrant 1”), and all such shares of Common Stock in the aggregate represent beneficial ownership of approximately 4.99% of the Common Stock, based on (1) 8,343,755 shares of Common Stock outstanding as of July 11, 2024, as reported by the Issuer, plus (2) 438,220 shares of Common Stock issuable upon exercise of Intracoastal Warrant 1. The foregoing excludes (I) 4,014,386 shares of Common Stock issuable upon exercise of Intracoastal Warrant 1 because Intracoastal Warrant 1 contains a blocker provision under which the holder thereof does not have the right to exercise Intracoastal Warrant 1 to the extent (but only to the extent) that such exercise would result in beneficial ownership by the holder thereof, together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates, of more than 4.99% of the Common Stock, (II) 3,443 shares of Common Stock issuable upon exercise of a second warrant held by Intracoastal (“Intracoastal Warrant 2”) because Intracoastal Warrant 2 contains a blocker provision under which the holder thereof does not have the right to exercise Intracoastal Warrant 2 to the extent (but only to the extent) that such exercise would result in beneficial ownership by the holder thereof, together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates, of more than 4.99% of the Common Stock and (III) 2,870 shares of Common Stock issuable upon exercise of a third warrant held by Intracoastal (“Intracoastal Warrant 3”) because Intracoastal Warrant 3 contains a blocker provision under which the holder thereof does not have the right to exercise Intracoastal Warrant 3 to the extent (but only to the extent) that such exercise would result in beneficial ownership by the holder thereof, together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates, of more than 4.99% of the Common Stock. Without such blocker provisions, each of the Reporting Persons may have been deemed to have beneficial ownership of 4,458,919 shares of Common Stock.

(c) Number of shares as to which each Reporting Person has:

(i) Sole power to vote or to direct the vote:          0         .

(ii) Shared power to vote or to direct the vote:          438,220         .

(iii) Sole power to dispose or to direct the disposition of          0         .

(iv) Shared power to dispose or to direct the disposition of          438,220        .
