Explanation of Responses:

( 1 )Each Performance-Based Restricted Share Unit ("PRSU") represents the right to receive one Issuer Common Share (or a cash payment equivalent thereto), plus cash dividend equivalents as applicable. ( 2 )In general, the PRSUs can be earned from 0% to 200% depending on the degree to which the Issuer's Common Shares satisfy up to seven specified average closing price goals (based on 20 consecutive trading days' achievement of a specified 20-trading-day average price) (the "Average Share Price Goals") from December 1, 2023 through December 31, 2026. Generally, PRSUs earned based on the Average Share Price Goals (or, if earlier, based upon performance evaluation through a change in control of the Issuer) then generally pay out (subject to a payment cap) in two equal installments in early 2027 and 2028, subject to certain alternative terms for death, disability or termination without cause.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
