Explanation of Responses:

( 1 )This Form 4/A is being filed by Aron English (the "Reporting Person") to amend the prior Form 4 filed by Mr. English and certain other reporting persons with the Securities and Exchange Commission on January 23, 2024. The prior Form 4 is hereby amended to correct the amount of Common Shares the Reporting Person received in the CA$30.0 million rights offering announced by the Issuer on January 9, 2024 (the "Rights Offering") to include an additional 22,776 Common Shares received pursuant to the Reporting Person's exercise of his oversubscription rights in connection with the closing of the Rights Offering. The Reporting Person did not receive confirmation of the final amount of Common Shares allocated pursuant to his oversubscription rights until after the filing of the prior Form 4. Accordingly, the total amount of Common Shares directly owned by the Reporting Person is 7,492,943. ( 2 )On January 9, 2024, the Issuer announced the results of the Rights Offering. Each subscription right was exercisable for 0.81790023 Common Shares, rounded down to the nearest whole number, together with oversubscription rights. The Reporting Person participated in the Rights Offering in full, as well as exercising his oversubscription rights, at a subscription price of CA$0.35 per Common Share. The number of Common Shares reported above includes the allocation pursuant to the Reporting Person's exercise of his oversubscription rights. ( 3 )Represents Canadian dollars (C$).
