Upon the Amendments becoming effective, each Warrant will be exercisable until 5:00 p.m. (Toronto time) on May 11, 2023 at an exercise price of C$4.25 per Common Share. In addition, the Warrants will be subject to an amended clause whereby, if for any 10 consecutive trading days during the unexpired term of the Warrants, the closing price of the Common Shares on the Exchange is equal to or greater than C$4.89, the expiry date will be accelerated to 30 calendar days (the " Acceleration Clause "). The Corporation will announce any such accelerated expiry date of the Warrants by news release. All other terms and conditions of the Warrants remain the same. The amended warrant terms remain subject to the final acceptance of the Exchange.
