Explanation of Responses:

( 1 )The option, representing a right to purchase a total of 25,000 shares, is fully exercisable as of the date hereof. ( 2 )The exercise price of the option of CAD$6.10 is converted to USD based on the daily average exchange rate as reported by the H.10 statistical release of the Board of Governors of the Federal Reserve System on September 27, 2019 of C$1.3250 = US$1.00. ( 3 )The option, representing a right to purchase a total of 15,000 shares, became exercisable as to 5,000 shares on November 21, 2017 and as to 5,000 shares on November 21, 2018, with the remainder to vest on November 21, 2019, subject to continued service through each vesting date. ( 4 )The exercise price of the option of CAD$5.76 is converted to USD based on the daily average exchange rate as reported by the H.10 statistical release of the Board of Governors of the Federal Reserve System on September 27, 2019 of C$1.3250 = US$1.00. ( 5 )Each deferred share unit is the economic equivalent of one share of the Issuer's Common Shares. Upon the Reporting Person's resignation, death or retirement from the board of directors of the Issuer, the deferred share units will be settled in cash based on a conversion price that is equal to, if the Common Shares are listed on more than one stock exchange, the volume weighted average price of the Common Shares for the five trading days on which the Common Shares were trading, based on the stock exchange with the higher average trading volume over the twenty trading days immediately prior to such date.
