A total of 6,846,444 of the 2018 Warrants and 3,350,000 of the 2019 Warrants are held directly or indirectly by insiders of the Company. The extension in respect of warrants held by insiders and their ability to exercise the 2018 Warrants after November 27, 2020 and the 2019 Warrants after April 15, 2020 will be subject to obtaining disinterested shareholder approval, which the Company intends to seek at the annual general and special meeting of shareholders of the Company scheduled for December 22, 2020.

The extensions of the warrants held by insiders of the Company constitute related party transactions within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions (" MI 61-101 "). The Company is relying on the exemptions from the valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101, as the fair market value of the participation in the Offering by each insider does not exceed 25% of the market capitalization of the Company, as determined in accordance with MI 61-101. The Company does not intend to file a material change report in respect of the extensions.
