With respect to 50% of the transition notional shares, the vesting date shall be on or any time after January 26, 2017 if the weighted average Canadian dollar closing price of Common Shares on the TSX for at least three consecutive calendar months has exceeded $2.58 per common share by at least 50%. The remaining 50% of the transition notional shares vest on January 26, 2019.
