In light of the rapidly evolving news and guidelines related to the COVID-19 outbreak, we ask that, in considering whether to attend the Meeting, shareholders follow the instructions and Guidelines of the Public Health Agency of Canada (https://www.canada.ca/en/public-health/services/diseases/coronavirusdisease-covid-19.html), particularly with respect to “social distancing” efforts, as well as all additional provincial and local instructions and guidance. You may still vote on the above items by submitting a Proxy. A form of Proxy has been provided in this package, together with an Information Circular which forms part of this Notice. Please refer to the Notes to the Proxy for instructions on completing the Proxy.
