In accordance with the policies of the TSXV, this proposed Warrant amendment will also include an accelerated expiry provision such that the exercise period of the Warrants will be reduced to thirty (30) days if, for any ten (10) consecutive trading days during the unexpired term of such Warrants (the "Premium Trading Days"), the closing price of the Company's Common Shares exceeds the amended exercise price by 25% or more, with the 30-day expiry period to begin no more than seven (7) calendar days after the 10^th Premium Trading Day.
