Filing notes and footnotes

Explanation of responses 3 footnotes

Footnote F1

On November 26, 2025, the reporting person was granted 752,000 performance share units (PSUs) which vested November 10, 2026. Each PSU represented 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 PSUs was C$0.84, which was the closing issuer's price on The Toronto Stock Exchange on November 9, 2026. The price was converted using the Bank of Canada exchange rate for November 10, 2026 of C$1.4181=US$1.00

Footnote F3

These shares were withheld upon the vesting of PSUs to pay tax withholding obligations.
