Article 1 - Restrictions on Transfer

1.1 Restrictions on Transfer. Each Shareholder acknowledges and agrees that during the period commencing on the date hereof and ending on July 1, 2022 (as modified in accordance with Section 1.2, the “Lock-up Period”), that such Shareholder will not, without the prior written consent of the Company (which consent may be withheld at the sole discretion of the Company), directly or indirectly, offer or sell, agree to offer or sell, or enter into an arrangement to offer or sell or otherwise transfer, pledge, assign or dispose of any of such Shareholder’s Class A subordinate voting shares in the capital of the Company (the “Subordinate Voting Shares”) or Class B subordinate proportionate voting shares in the capital of the Company (the “Subordinate Proportionate Voting Shares”, or options which have an effective strike price per Subordinate Voting Share less than the closing price of such on the Canadian Stock Exchange as of the date of this Agreement (“ITM Options,” and together with the Subordinate Voting Shares and Proportionate Voting Shares, the “Shares”), or any Shares controlled by such Shareholder, in each case as set forth in Schedule “A” hereto, or enter into any swap, forward or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of such Shareholder’s Shares (regardless of whether any such arrangement is to be settled by the delivery of securities of the Company, securities of another person, cash or otherwise), or shares which such Shareholder controls, or agree to do any of the foregoing or publicly announce any intention to do any of the foregoing.

1.2 Release Schedule. Notwithstanding Section 1.1, the Parties acknowledge and agree that each Shareholder’s Shares will be released from the restrictions set forth in Section 1.1 in accordance with the release schedule set forth in Schedule “B” hereto as the same may be accelerated as set forth in Schedule “B” (the “Release Schedule”) and that such restrictions are subject in their entirety to the Release Schedule.

1.3 Shares Subject to Lock-Up. The only Shares subject to this Agreement are (a) the Shares set forth in Schedule “A” hereto; and (b) any Subordinate Voting Shares into which the Proportionate Voting Shares set forth in Schedule “A” have converted.

1.4 Permitted Transfers. The restrictions provided herein shall not apply to the following transfers, pledges or other dispositions by a Shareholder:

(a) transfers to affiliates of such Shareholder, any family members of such Shareholder, or any company, trust or other entity wholly owned by or maintained for the benefit of such Shareholder and/or any family members of such Shareholder, or for charitable purposes;

(b) transfers as a distribution to limited partners, members or shareholders of such Shareholder, as the case may be;

(c) transfers occurring by operation of law, pursuant to a domestic relations order or in connection with transactions arising as a result of the death or incapacity of such Shareholder; or

(d) pledges of such Shareholder’s Shares as security for bona fide indebtedness of such Shareholder or such Shareholder’s family members or affiliates (as applicable);

(e) pledges of such Shareholder’s Shares as security for bona fide indebtedness of the Company, its subsidiaries and affiliates, or otherwise for the benefit of the Company, all conditional upon board consent;

provided, in the case of each of (a), (b), (c) and, solely as to pledges entered into within the Lockup Period, (d) (in the case of (c) to the extent permissible under applicable law or the applicable order), that any such transferee or pledgee shall first execute a lock-up agreement in substantially the form of this Agreement covering the remainder of the Lock-up Period, as applicable, or

(f) transfers or other dispositions made pursuant to a bona fide take-over bid made to all of the holders of Subordinate Voting Shares or all of the holders of Subordinate Proportionate Voting Shares or other acquisition, merger, tender or exchange offer, business combination or arrangement transaction; provided that, in the event that the take-over or other acquisition, merger, tender or exchange offer, business combination or arrangement transaction is not completed, any securities shall remain subject to the restrictions contained in this Agreement.

For the purposes of this Agreement, “affiliate” shall have the meaning ascribed to such term in the British Columbia Business Corporations Act.

1.5 Release. Following the expiration of each applicable Lock-Up Period, the applicable portion of each Shareholder’s Shares shall be released from the restrictions herein automatically without the taking of any further action on the part of any Party. Each Shareholder acknowledges and agrees that such Shareholder is subject to restrictions pursuant to applicable securities laws regarding insider trading and reporting, and such restrictions are separate and apart from those restrictions contained herein.

1.6 Adjustment. If, following the date hereof, any change in the outstanding shares of the Company, or securities convertible into or exchangeable into or exercisable for shares of such capital stock, shall occur by reason of any reclassification, recapitalization, stock split (including reverse stock split) or subdivision or combination, exchange or readjustment of shares, merger or similar transaction, or any stock dividend or stock distribution with a record date after the date hereof, each Shareholder’s Shares subject to the lock-up restrictions set forth herein and the releases from such restrictions shall be appropriately adjusted to reflect such change and such adjustment shall provide each Shareholder with the same economic effect as contemplated by this Agreement prior to such change.

1.7 Trading Volume. The Company agrees that, to the extent the median daily volume of trading of the Subordinate Voting Shares on the Canadian Securities Exchange (“CSE”) and any other exchange on which the Subordinate Voting Shares are then traded is in excess of US$5 million (calculated by reference to the number of Subordinate Voting Shares so traded, in each case, multiplied by the trading price for such Subordinate Voting Share) over 20 consecutive trading days, it will consider whether any of the restrictions contained in this Agreement should be adjusted.
