Schedule of Percentage of PRSUs Vest upon Increases of Share Price

The Company granted to certain executives and senior employees restricted share units with service and performance-based conditions for vesting (the “PRSUs”). If the Company’s share price increases to certain values for 20 consecutive trading days, as outlined below, a percentage of the PRSUs will vest at the end of the three-year service period. The grant date fair value of the PRSUs were valued using the Monte Carlo valuation method and determined to have a weighted average grant date fair value of C$3.27 (2020 – C$1.70).
