Registered shareholders and duly appointed proxyholders will be able to virtually attend the Meeting and vote (to the extent of any voting rights as described below) in real time, provided they follow the instructions in the attached Circular. Non-registered shareholders who have not duly appointed themselves as proxyholder will be able to virtually attend (as guests) but not be able to vote or speak at the Meeting. Only Class A participating shareholders of record at the close of business on January 16, 2026 will be entitled to vote at the Meeting, except to the extent that a shareholder of record has transferred any shares after that date and the transferee of such shares establishes proper ownership and requests, not later than 10 days before the Meeting, that the transferee's name be included in the list of shareholders entitled to vote at the Meeting.

Class A participating shareholders who do not expect to virtually attend the Meeting are requested to complete the accompanying proxy or voting instruction form and mail it to TSX Trust Company, Attention: Proxy Department, P.O. Box 721, Agincourt, Ontario, M1S 0A1. A self-addressed envelope is provided for this purpose. Alternatively, shareholders may, with the control number, vote online at www.meeting-vote.com or by smartphone using the QR code provided.

Shareholders who wish to appoint a person other than the management nominees identified in the form of proxy or voting instruction form (including a non-registered shareholder who wishes to appoint themselves to attend the virtual Meeting) must carefully follow the instructions in the attached Circular and on their form of proxy or voting instruction form. These instructions include the step of registering such proxyholder with the Company's transfer agent, TSX Trust Company, after submitting the form of proxy or voting instruction form. Failure of a proxyholder to register with the transfer agent will result in the proxyholder not receiving a control number to participate in the Meeting and only being able to attend as a guest.

Holders of Class A participating shares of the Company will be entitled to vote separately as a class on any resolution put forward at the Meeting.
