COVID-19 GUIDANCE

In the context of the effort to mitigate potential risk to the health and safety associated with COVID-19 and in compliance with the orders and directives of the Government of Canada, the Province of Ontario and the City of Toronto, shareholders are being discouraged from attending the Meeting in person. All shareholders are encouraged to vote on the matters before the Meeting by proxy in the manner set out herein and in the accompanying management information circular dated May 9, 2022 of the Company (the “Circular”). The Company is offering its shareholders the option to watch and listen to the Meeting via Zoom. Shareholders attending via Zoom will not be able to participate and vote at the Meeting. Please see details on how to watch and listen to the Meeting in the accompanying Circular.

NOTICE-AND-ACCESS

Notice is also hereby given that the Company has decided to use the notice-and-access method of delivery of meeting materials for the Meeting for beneficial owners of common shares of the Company (the “ Non-Registered Holders ”) and for registered shareholders. The notice-and-access method of delivery of meeting materials allows the Company to deliver the meeting materials over the internet in accordance with the notice-and-access rules adopted by the Ontario Securities Commission under National Instrument 54-101 – Communication with Beneficial Owners of Securities of a Reporting Issuer . Under the notice-and-access system, registered shareholders will receive a form of proxy and the Non-Registered Holders will receive a voting instruction form enabling them to vote at the Meeting. However, instead of a paper copy of the notice of Meeting, the management information circular, the annual consolidated financial statements of the Company for the financial year ended December 31, 2021 and related management’s discussion and analysis and other meeting materials (collectively the “ Meeting Materials ”), shareholders receive a notification with information on how they may access such materials electronically. The use of this alternative means of delivery is more environmentally friendly as it will help reduce paper use and will also reduce the cost of printing and mailing the Meeting Materials to shareholders. Shareholders are reminded to view the Meeting Materials prior to voting. The Company will not be adopting stratification procedures in relation to the use of notice-and access provisions.
