(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 2021 have a weighted average value of $15.54 per DSU ($12.35 per DSU in 2020).

(ii) On December 31, 2019, 150,000 RSU were granted to an officer (with a value of $12.70 per RSU), which vest and are 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 75,000 RSU were also granted (with a value of $12.70 per RSU) and vested during the three months ended March 31, 2020 following the acquisition by the officer of a total of 75,000 common shares of the Company. A total of 34,852 common shares were issued to the officer (after deducting the income taxes payable on the benefit earned by the employee that must be remitted by the Company to the tax authorities). 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 Development to the tax authorities. The RSU granted in 2021 have a weighted average value of $13.24 per RSU ($13.56 per RSU in 2020).

(ii) Following the closing of the reverse takeover transaction completed on November 25, 2020, which lead to the creation of Osisko Development and the subsequent transfer of certain Osisko employees to Osisko Development on January 1, 2021, Osisko and Osisko Development mutually agreed that a pro-rata portion of the outstanding long-term equity incentive compensation awarded by Osisko to the transferred employees in the form of RSU would be borne by Osisko Development. As a result, a pro-rata portion of the outstanding RSU awarded by Osisko (the "Osisko RSU") to the transferred employees were cancelled, and RSU (the "Replacement RSU") having a relative equivalent value were granted by Osisko Development. Accordingly, in June 2021, 458,450 Replacement RSU were granted to officers and employees who held Osisko RSU that were cancelled. The maturity date of the Replacement RSU is the same as the maturity date of the corresponding Osisko RSU that were cancelled.
