Explanation of Responses:
1. The price used to calculate the August 14 RSU vesting was C$0.83, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on August 14, 2026. The price was converted using the Bank of Canada exchange rate for August 14, 2026 of C$1.3875= US$1.00.
2. On August 14, 2024, the reporting person was granted 1,000,000 RSUs vesting on August 14, 2026. 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. The RSUs vested on August 14, 2026 and were coverted into Common Stock on a one-to-one basis at the Issuer's discretion.
3. On August 14, 2024, the reporting person was granted 100,000 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. The RSUs vested on August 14, 2026 and were coverted into Common Stock on a one-to-one basis at the Issuer's discretion.
