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 Guelph, the 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 of the Corporation dated August 19, 2021 (the "Circular"). If a shareholder wishes to attend to Meeting in person, shareholders must provide the Corporation with proof that they have been fully vaccinated against the COVID-19 virus.

Voting

All Shareholders are invited to attend the Meeting and may attend in person or may be represented by proxy. A "beneficial" or "non-registered" Shareholder will not be recognized directly at the Meeting for the purposes of voting common shares registered in the name of his/her/its broker; however, a beneficial Shareholder may attend the Meeting as proxyholder for the registered Shareholder and vote the common shares in that capacity. Only Shareholders as of the Record Date are entitled to receive notice of and vote at the Meeting. Shareholders who are unable to attend the Meeting in person, or any adjournments or postponements thereof, are requested to complete, date and sign the enclosed form of proxy (registered holders) or voting instruction form (beneficial holders) and return it in the envelope provided. To be effective, the enclosed form of proxy or voting instruction form must be mailed or faxed so as to reach or be deposited with Capital Transfer Agency ULC (in the case of registered holders) at 390 Bay Street, Suite 920, Toronto, Ontario M5H 2Y2, Fax Number: 416.350.5008, prior to the Proxy Deadline, failing which such votes may not be counted, or your intermediary (in the case of beneficial holders) with sufficient time for them to file a proxy by the Proxy Deadline.

NOTICE-AND-ACCESS

Notice is also hereby given that the Corporation 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 Corporation (the "Non-Registered Holders") and for registered shareholders. The notice-and-access method of delivery of meeting materials allows the Corporation 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 Corporation for the financial year ended March 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 Corporation will not be adopting stratification procedures in relation to the use of notice-and access provisions.
