**Item 4. Ownership:**

**(a) Amount beneficially owned:**

As of the date hereof, each of WA and WGP is deemed to be the beneficial owner of 9,271,572 Common Shares, as a result of WA's clients' ownership of 9,271,572 Common Shares.
WA's clients also own (i) 28,884,464 warrants to purchase Common Shares at an exercise price of $1.25 per Common Share (the "October 2025 Warrants") and (ii) 21,920,001 pre-funded warrants to purchase Common Shares at an exercise price of $0.000001 per Common Share (the "Pre-Funded Warrants" and, together with the October 2025 Warrants, the "Warrants"), with each of (i) and (ii) subject to the Beneficial Ownership Limitations (defined below). Warrants are subject to a blocker which prevents the holder from exercising Warrants to the extent that, upon such exercise, the holder would beneficially own in excess of 9.9% of Common Shares outstanding as a result of the exercise (the "Beneficial Ownership Limitations").
