¹ On May 4, 2022, the Common Shares were consolidated on the basis of one post-consolidation Common Share for every three pre-consolidation Common Shares (the "Share Consolidation"). Accordingly, the number of Common Shares and Warrants issued upon the conversion of the Subscription Receipts (which, for the avoidance of doubt, were issued prior to the Share Consolidation) has been adjusted to give effect to the Share Consolidation.
