F1	On August 14, 2024, the reporting person was granted 300,000 RSUs, vesting in three equal annual installments beginning on the first anniversary of the grant date. Each RSU represents a conditional right to receive a cash payment equal to the fair market value of one Common Share of the Issuer or, at the Issuer's discretion, a number of Common Shares (or a combination of cash and Common Shares) equal to the fair market value of one Common Share. One-third of the RSUs vested on August 14, 2025 and were converted into Common Stock on a one-to-one basis at the Issuer's discretion.
F2	The price used to calculate the August 14 RSU vesting was C$0.78, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on August 13, 2025. The price was converted using the Bank of Canada exchange rate for August 13, 2025 of C$1.3767 = US$1.00.
