        <footnote id="F1">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.</footnote>
