COVID-19 SAFETY PROTOCOLS

The Corporation will be following stringent safety protocols for the Meeting as a result of the coronavirus pandemic (“ COVID-19 ”). Registered shareholders and properly appointed proxy holders who wish to attend the Meeting in person will be required to present their identification and a copy of their completed proxy or other proof of their status as a shareholder or valid proxy holder, complete the Company’s sign-in and COVID screening, not enter with any food or drink, wear masks covering their nose and chin at all times while inside the building, and maintain appropriate physical distancing at all times. The capacity of the Corporation’s offices is limited and those choosing to attend in person will be accommodated on a “first-come first-served” basis. No one other than registered shareholders and properly appointed proxy holders will be allowed to attend the Meeting in person to ensure adequate space is available for those registered shareholders and properly appointed proxy holders who wish to attend the Meeting. All shareholders are strongly urged to send in their proxies in advance of the Meeting as set out in the Circular below and as set out in the proxy or voting instruction form mailed to registered shareholders and Non-Objecting Beneficial Owners (“NOBO”) to ensure that their votes are counted at the Meeting. The lockdown resulting from the outbreak of COVID-19 has created unprecedented disruptions in the global economy and required the Corporation to take all necessary precautions to ensure the health and safety of its officers, directors, employees and shareholders. Given the fact that the spread of COVID-19 in certain areas of the country has increased recently and new restrictions have been imposed resulting from the anticipated increase in COVID-19 cases, the Corporation needs to continue to take appropriate precautions while proceeding with the Meeting. In order to provide some accommodation to those shareholders unable or unwilling to attend in person, the Corporation has set up a conference call number for shareholders and guests to phone in and listen to the Meeting

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 2021 Annual General and Special Meeting of 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 noticeand-access system, shareholders still receive a proxy or voting instruction form (as applicable) enabling them to vote at the Meeting. However, instead of a paper copy of the Circular, the Annual Financial Statements and related Annual MD&A and other meeting materials (collectively the “Meeting Materials”), shareholders receive a notification (the “Notice-and-Access 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 materials to shareholders. Shareholders are reminded to view the Meeting Materials prior to voting.
