Explanation of Responses:

( 1 )In connection with the cessation of the Reporting Person's service as a director of the Issuer, the Reporting Person received Common Shares in settlement of outstanding Deferred Share Units ("DSUs"). ( 2 )The DSUs are held directly and solely by Mr. Watsa and were received in connection with service as a director of the Issuer. Each DSU is the economic equivalent of one common share. ( 3 )Each of the Reporting Persons disclaims beneficial ownership of the securities reported herein for purposes of Rule 16a-1(a) under the Exchange Act, except to the extent of its or his pecuniary interest therein, if any. This report shall not be deemed an admission that other Reporting Persons are beneficial owners of the securities reported herein for purposes of Rule 16a-1(a) under the Exchange Act. ( 4 )These securities are held by The Second 810 Holdco Ltd ("810 Holdco"). Mr. Watsa is the controlling person of 810 Holdco. ( 5 )These securities are held by wholly-owned subsidiaries of Fairfax Financial Holdings Limited. Mr. Watsa is the CEO and controlling person of Fairfax Financial Holdings Limited through the other Reporting Persons. ( 6 )The 1.75% extendable convertible unsecured debentures (the "Debentures") were repaid at par upon maturity by the Issuer. The Debentures had a maturity date of February 15, 2024 and were convertible at any time into common shares of the Issuer at an initial conversion price of $6.00 per common share (for a total value of $150,000,000, which was inadvertently stated as $150,000 in the Form 4 filed on November 15, 2023 (as was the $330,000 stated in the same Form 4, which should have read $330,000,000), both of which amounts are deemed amended by the filing of this Form 4), subject to adjustments in accordance with the terms of such Debentures. None of the Debentures were converted into common shares of the Issuer prior to repayment.

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