Explanatory Note:

This Amendment No. 1 to Schedule 13G is filed jointly on behalf of Jeremy M. Sclar, Crocker Mountain LLC, a Maine limited liability company (“Crocker Mountain”), and the Jeremy M. Sclar 2012 Irrevocable Family Trust (the “JS Trust,” and collectively with Mr. Sclar and Crocker Mountain, the “Reporting Persons”), pursuant to Rule 13d-1(c). Prior to the effective date of the registration of the Issuer’s common shares, no par value per share (“Common Shares”), pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, in July of 2022, (i) Mr. Sclar acquired 65,000 Common Shares, which appear to represent approximately 3,900,000 Common Shares prior to a 60:1 stock split (the “Stock Split”) of the Issuer that occurred in June 2022, (ii) Crocker Mountain acquired (a) 20,449,980 Common Shares, representing 340,833 Common Shares following the Stock Split, (b) 9,000,000 Series 1 Preferred Shares (“Series 1 Preferred Shares”) of the Issuer, each initially convertible into one Common Share in accordance with the terms of the Series 1 Preferred Shares and, as a result of the Stock Split, now convertible into an aggregate of 150,000 Common Shares and (c) 5,112,480 warrants to purchase Common Shares, representing 85,208 warrants to purchase Common Shares following the Stock Split, each exercisable to purchase one Common Share and (iii) the JS Trust acquired 9,000,000 Series 1 Preferred Shares, each initially convertible into one Common Share in accordance with the terms of the Series 1 Preferred Shares and, as a result of the Stock Split, now convertible into an aggregate of 150,000 Common Shares. On October 11, 2022, the JS Trust acquired 104,869 Common Shares in a private placement conducted by the Issuer. On August 24, 2023, Crocker Mountain and JS Trust acquired 664,893 and 664,894 common share units (“Common Share Units”), respectively, each consisting of one Common Share and one warrant to purchase one Common Share (the “August 2023 Warrants”), in a private placement conducted by the Issuer.
