Obtaining Paper Copies of the Proxy Materials

The Canadian securities regulators have adopted rules which permit the use of notice-and-access for proxy solicitation instead of the traditional physical delivery of material. This process provides the option to post meeting related materials including management information circulars, as well as annual financial statements and management’s discussion and analysis on a website in addition to SEDAR+.

Securityholders may request to receive paper copies of the proxy materials related to the above referenced meeting by mail at no cost. Requests for paper copies must be received by May 31, 2024 in order to receive the paper copy in advance of the meeting. Shareholders may request to receive a paper copy of the Materials for up to one year from the date the Materials were filed on www.sedar.com.

For more information regarding notice-and-access or to obtain a paper copy of the Materials you may contact our transfer agent, Odyssey Trust Company, via www.odysseycontact.com or by phone at 1- 888-290-1175 (toll-free within North America) or 1-587-885-0960 (direct from outside North America).
