The accompanying Information Circular provides additional information relating to the matters to be dealt with at the Meeting and is supplemental to, and expressly made a part of, this Notice of Meeting.

The Board of Directors of the Company has fixed August 7, 2020 as the record date for the determination of shareholders entitled to notice of and to vote at the Meeting and at any adjournment or postponement thereof. Each registered shareholder at the close of business on that date is entitled to such notice and to vote at the Meeting in the circumstances set out in the accompanying Information Circular.

To proactively deal with the unprecedented public health impact of the coronavirus, also known as COVID19 (“COVID-19”) and recent Provincial and Federal guidance regarding public gatherings, shareholders and proxyholders are strongly encouraged NOT to attend the Meeting in person. The COVID-19 virus is causing unprecedented social and economic disruption and we want to ensure that no one is unnecessarily exposed to any risks. Furthermore, so that the Company can mitigate potential risks to the health and safety of shareholders and the community, there will be strict limitations on the number of persons permitted entry to the Meeting and anyone who is not a registered shareholder or proxyholder will not be permitted entry.

The Company urges all shareholders to vote by proxy in advance of the Meeting in accordance with the instructions set out below. The COVID-19 situation is dynamic and continues to evolve daily. If events arise that require us to make changes to the date, time and/or location of the Meeting we will promptly notify shareholders and communicate any changes through a press release. The Company intends to resume holding unrestricted in-person shareholder’s meetings in future years.

If you are a registered shareholder of the Company and unable to attend the Meeting in person, please complete, date and sign the accompanying form of proxy and deposit it with the Company’s transfer agent, TSX Trust Company: by mail or registered mail at 301 – 100 Adelaide Street West, Toronto, Ontario M5H 4H1, or via the Internet at www.voteproxyonline.com, or by facsimile at 416-595-9593, at least 48 hours (excluding Saturdays, Sundays and holidays recognized in the Province of British Columbia) before the time and date of the Meeting or any adjournment or postponement thereof.

If you receive more than one form of proxy because you own common shares registered in different names or addresses, each form of proxy should be completed and returned.

The form of proxy confers discretionary authority with respect to: (i) amendments or variations to the matters of business to be considered at the Meeting; and (ii) other matters that may properly come before the Meeting. As of the date hereof, management of the Company knows of no amendments, variations or other matters to come before the Meeting other than the matters set forth in this Notice of Meeting. Shareholders who are planning on returning the applicable accompanying form of proxy are encouraged to review the Information Circular carefully before submitting the proxy form. It is the intention of the persons named in the enclosed applicable form of proxy, if not expressly directed to the contrary in such form of proxy, to vote IN FAVOUR of the resolutions proposed by management as set forth under “Particulars of Matters to be Acted Upon” in the accompanying Information Circular .
