[1] The warrants are subject to an acceleration clause such that if the volume-weighted average trading price of the Company's common shares on the TSX-V exceeds $0.12 per common share for a period of 10 consecutive trading days at any date before the expiration date of such warrants, the Company may, at its option, accelerate the warrant expiry date to within 30 days. To March 31, 2021, the Company's common shares have met the criterion for acceleration. The Company, however, has not accelerated the warrant expiry date.
