All of the persons named in the accompanying proxy are current directors or officers of the Company. If a shareholder wishes to appoint some other person (who need not be a shareholder) to represent that shareholder at the Meeting, the shareholder may do so either by (i) striking out the printed names and inserting the desired person’s name in the blank space provided in the proxy or (ii) completing another proper proxy and, in either case, delivering the completed and executed proxy to the Company’s transfer agent, Computershare Investor Services Inc., Proxy Dept., 100 University Avenue, 9****th Floor, Toronto, Ontario, Canada M5J 2Y1, by not later than 9:30 a.m. (Pacific Daylight Time) on Monday, June 2, 2025 or, in the event the Meeting is postponed or adjourned, not less than two business days prior to the day set for the recommencement of such postponed or adjourned Meeting. Proxies delivered after such times will not be accepted or acted upon.

To be valid, the proxy must be dated and be signed by the shareholder or by a duly appointed attorney for such shareholder, or, if the shareholder is a corporation, it must either be under its common seal or signed by a duly authorized officer. If a proxy is signed by a person other than the registered shareholder, or by an officer of a registered corporate shareholder, the Chair of the Meeting may require evidence of the authority of such person to sign before accepting such proxy.

THE SHARES REPRESENTED BY A PROXY WILL BE VOTED OR WITHHELD FROM VOTING BY THE PROXYHOLDER IN ACCORDANCE WITH THE INSTRUCTIONS OF THE PERSON APPOINTING THE PROXYHOLDER ON ANY BALLOT THAT MAY BE CALLED FOR AND, IF A CHOICE HAS BEEN SPECIFIED WITH RESPECT TO ANY MATTER TO BE ACTED UPON, THE SHARES WILL BE VOTED ACCORDINGLY.

If a choice with respect to any proposal is not specified or if more than one choice has been specified for the same proposal, the person appointed proxyholder will vote the securities represented by the proxy as recommended by the Board.
