4Front Ventures Corp. — Proxy Solicitation & Information Statement 2020

Nov 20, 2020

NOTICE-AND-ACCESS NOTIFICATION for the Annual and Special Meeting of Shareholders to be held on December 21, 2020

Holders (the “ Shareholders ”) of subordinate voting shares (“ Subordinate Voting Shares ” or “ SVS ”), subordinate proportionate voting shares (“ Subordinate Proportionate Voting Shares ” or “ SPVS ”) and multiple voting shares (“ Multiple Voting Shares ” or “ MVS ” and collectively with SVS and SPVS, the “ Shares ”) of 4Front Ventures Corp. (the “ Company ”) are receiving this notification as the Company has opted to use the notice-and-access model for delivery of meeting materials to its Shareholders in accordance with National Instrument 51-102 - Continuous Disclosure Obligations (“ NI 51-102 ”) and National Instrument 54-101 - Communication with Beneficial Owners of Securities of a Reporting Issuer (“ NI 54-101 ” and together with NI 52-102, “ Notice-and-Access ”).

Notice-and-Access reduces the volume of materials that must be physically mailed to securityholders by allowing issuers to deliver meeting materials to securityholders electronically by providing securityholders with access to these materials online. Notice-and-Access will be used to deliver the meeting materials to Shareholders. The Company will not be using the procedure known as “stratification” to deliver a paper copy of the meeting materials to any Shareholders with this notice.

Under Notice-and-Access, Shareholders still receive a form of proxy or voting instruction form enabling them to vote at the shareholders’ meeting. However, instead of a paper copy of the management information circular dated November 19, 2020 (the “ Circular ”), Shareholders receive this notice-and-access notification with information on how they may access the Circular and other relevant meeting materials electronically. The use of this alternative means of delivery is more environmentally friendly as it will help reduce paper use and also will reduce the cost of printing and mailing materials to Shareholders.
