(i) Unless otherwise decided by the Board of Directors of the Company, the DSU vest the day prior to the next annual general meeting and are payable in common shares, cash or a combination of common shares and cash, at the sole discretion of the Company, to each non-executive director when he or she leaves the board or is not re-elected. The value of the payout is determined by multiplying the number of DSU expected to be settled at the payout date by the closing price of the Company's shares on the day prior to the grant date. The fair value is recognized over the vesting period. On the settlement date, one common share will be issued for each DSU, after deducting any income taxes payable on the benefit earned by the director that must be remitted by the Company to the tax authorities. The DSU granted in 2022 have a weighted average value of $14.71 per DSU ($15.54 per DSU in 2021).

(ii) On December 31, 2019, 150,000 RSU were granted to an officer (with a value of $12.70 per RSU), which vested and were payable in equal tranches over a three-year period (1/3 per year), in common shares, cash or a combination of common shares and cash, at the sole discretion of the Company. An additional number of 75,000 RSU were also granted (with a value of $12.70 per RSU) and vested in 2021 following the acquisition by the officer of a total of 75,000 common shares of the Company.

The remaining RSU vest and are payable in common shares, cash or a combination of common shares and cash, at the sole discretion of the Company, three years after the grant date, one half of which depends on the achievement of certain performance measures.

The value of the payout is determined by multiplying the number of RSU expected to be vested at the payout date by the closing price of the Company's shares on the day prior to the grant date. The fair value is recognized over the vesting period and is adjusted in function of the applicable terms for the performance-based components, when applicable. On the settlement date, one common share is issued for each RSU, after deducting any income taxes payable on the benefit earned by the employee that must be remitted by Osisko to the tax authorities. The RSU granted in 2022 have a weighted average value of $14.26 per RSU ($13.24 per RSU in 2021).
