Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

On November 26, 2025, the reporting person was granted 200,000 restricted share units ("RSUs") which vested immediately. Each RSU represents a conditional right to receive a cash payment equal to the fair market value of one Common Share 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.

Footnote F2

The price used to calculate the November 26 RSU vesting was C$1.01, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on November 25, 2025. The price was converted using the Bank of Canada exchange rate for November 25, 2025 of C$1.4104= US$1.00
