(the "Company")

- and -

COMPUTERSHARE TRUST COMPANY OF CANADA, a trust company under the laws of Canada, as trustee for the benefit of the SVS Holders (as defined below)

(the "Trustee")

- and -

each of the persons listed in Schedule "A" hereto, and any person who becomes a party to this Agreement by executing an adoption agreement in the form set forth in Schedule "B" hereto (collectively, the "Shareholders")

WHEREAS by articles of amendment effective on May 24, 2018, the Company amended its articles (which, as amended, are referred to as the "Articles") to amend and re-designate its existing common shares as Class B subordinating voting shares (the "Subordinate Voting Shares") and to create a class of Class A multiple voting shares (the "Multiple Voting Shares");

AND WHEREAS the Shareholders, on the date hereof, hold at least 80% of the Multiple Voting Shares that are issued and outstanding as of the date of this Agreement;

AND WHEREAS it is the expectation of the Shareholders that the Subordinate Voting Shares will be listed on the Canadian Stock Exchange (the "CSE");

AND WHEREAS the Shareholders and the Company wish to enter into this Agreement in order to secure the listing of the Subordinate Voting Shares on the CSE, and derive the benefit of such listing, and for the purpose of ensuring that the holders, from time to time, of the Subordinate Voting Shares (collectively, the "SVS Holders") will not be deprived of any rights under applicable take-over bid legislation to which they would have been entitled in the event of a take-over bid for the Multiple Voting Shares if the Multiple Voting Shares had been Subordinate Voting Shares;

AND WHEREAS pursuant to the Articles, Multiple Voting Shares will, inter alia, automatically convert into Subordinate Voting Shares upon any Transfer that is not a Transfer to a Permitted Holder (as such terms are defined in the Articles)

AND WHEREAS the Shareholders and the Company hereby acknowledge that any Transfer of Multiple Voting Shares, whether in accordance with this Agreement or otherwise, shall in all circumstances be subject to the provisions of the Articles, including those relating to the automatic conversion of Multiple Voting Shares into Subordinate Voting Shares;

- 2 -

AND WHEREAS the Shareholders and the Company wish to constitute the Trustee as a trustee for the SVS Holders so that the SVS Holders, through the Trustee, will receive the benefits of this Agreement, including the covenants of the Shareholders and the Company contained herein;

AND WHEREAS these recitals and any statements of fact in this Agreement are, and shall be deemed to be, made by the Shareholders and the Company and not by the Trustee;

NOW THEREFORE in consideration of the mutual covenants and agreements contained in this Agreement and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged by each of the parties) the parties hereto agree as follows:

1.1 Definitions

In this Agreement, capitalized terms that are not otherwise defined shall have the meaning given to them in the Articles.

1.2 Interpretation not Affected by Headings, etc.

The division of this Agreement into articles, sections and paragraphs and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation of this Agreement.

1.3 Number, Gender, etc.

Words importing the singular number only shall include the plural and vice versa. Words importing the use of any gender shall include all genders.

Unless otherwise indicated, all references in this Agreement to any legislation include the regulations and rules thereunder, in each case as amended, re-enacted, consolidated or replaced from time to time and in the case of any such amendment, re-enactment, consolidation or replacement, reference herein to a particular provision shall be read as referring to such amended, re-enacted, consolidated or replaced provision.

1.5 Including

The word "including" shall mean including, without limitation.

ARTICLE 2

PURPOSE OF AGREEMENT

2.1 Establishment of Trust

The purpose of this Agreement is to ensure that the SVS Holders will not be deprived of any rights under applicable take-over bid legislation in any jurisdiction of Canada ("Securities Laws") to which they would have been entitled in the event of a take-over bid for the Multiple Voting Shares if the Multiple Voting Shares had been Subordinate Voting Shares.

- 3 -

2.2 Restriction on Sale

Subject to Section 2.3 and the Articles, the Shareholders shall not sell, directly or indirectly, any Multiple Voting Shares pursuant to a take-over bid (as defined in applicable Securities Laws) under circumstances in which applicable Securities Laws would have required the same offer to be made to SVS Holders if the sale by the Shareholders had been a sale of the Subordinate Voting Shares underlying such Multiple Voting Shares rather than such Multiple Voting Shares, but otherwise on the same terms.

For the purposes of this Section 2.2, it shall be assumed that the offer that would have resulted in the sale of Multiple Voting Shares (or Subordinate Voting Shares into which such Multiple Voting Shares are convertible or converted pursuant to the Articles) by the Shareholders would have constituted a take-over bid for the Subordinate Voting Shares under applicable Securities Laws, regardless of whether this actually would have been the case, and the varying of any material term of an offer shall be deemed to constitute the making of a new offer.

2.3 Permitted Sale

Subject to the provisions of the Articles, Section 2.2 shall not apply to prevent a sale by any Shareholder of Multiple Voting Shares if concurrently an offer is made to purchase Subordinate Voting Shares that:

(a) offers a price per Subordinate Voting Share at least as high as the highest price per share paid or required to be paid pursuant to the take-over bid for the Multiple Voting Shares;

(b) provides that the percentage of outstanding Subordinate Voting Shares to be taken up (exclusive of shares owned immediately prior to the offer by the offeror or persons acting jointly or in concert with the offeror) is at least as high as the percentage of outstanding Multiple Voting Shares to be sold (exclusive of Multiple Voting Shares owned immediately prior to the offer by the offeror and persons acting jointly or in concert with the offeror);

(c) has no condition attached other than the right not to take up and pay for Subordinate Voting Shares tendered if no shares are purchased pursuant to the offer for Multiple Voting Shares; and

(d) is in all other material respects identical to the offer for Multiple Voting Shares.

In addition, and notwithstanding the foregoing, subject to the provisions of the Articles, Section 2.2 shall not apply to prevent the sale of Multiple Voting Shares by any Shareholder to a Permitted Holder, subject to Section 2.7 of this Agreement, provided such sale does not or would not constitute a take-over bid or, if so, is exempt or would be exempt from the formal bid requirements (as defined in applicable Securities Laws).

For greater certainty, the conversion of Multiple Voting Shares into Subordinate Voting Shares shall not, in of itself, constitute a sale of Multiple Voting Shares for the purposes of this Agreement.

- 4 -

2.4 Improper Sale

If any person or company, other than the Shareholders, carries out or purports to carry out a sale (including an indirect sale) of Multiple Voting Shares that the Shareholders are restricted from carrying out pursuant to Section 2.2, the Shareholders shall not and the Trustee shall take all necessary steps to ensure that the Shareholders shall not and shall not be permitted to, at or after the time such sale becomes effective, do any of the following with respect to any of the Multiple Voting Shares so sold or purported to be sold:

(a) sell them without the prior written consent of the Trustee;

(b) convert them into Subordinate Voting Shares without the prior written consent of the Trustee; or

(c) exercise any voting rights attaching to them except in accordance with the written instructions of the Trustee, with which the Shareholders shall comply.

Without limiting the generality of the foregoing, the Trustee shall exercise the above rights in a manner that the Trustee, on the advice of counsel, considers to be: (i) in the best interests of the SVS Holders, other than the Shareholders and SVS Holders who, in the opinion of the Trustee, participated directly or indirectly in the transaction that triggered the operation of this Section 2.4; and (ii) consistent with the intentions of the Shareholders and the Company in entering into this Agreement as such intentions are set out in the Recitals hereto. In the event that an indirect sale of Multiple Voting Shares that is referred to in this Section 2.4 occurs and this Section 2.4 is applicable to such sale, the Shareholders shall have no liability under this Agreement in respect of such sale, provided that the Shareholders are in compliance with all other provisions of this Agreement, including the provisions of this Section 2.4.

2.5 Assumptions

For the purposes of this Article 2:

(a) any sale, transfer or other disposition that would result in a direct or indirect acquisition of Multiple Voting Shares or Subordinate Voting Shares, or in the direct or indirect acquisition of control or direction over those shares, shall be construed to be a "sale" of those Multiple Voting Shares or Subordinate Voting Shares, as the case may be, and the terms "sell" and "sold" shall have a corresponding meaning; and

(b) if there is an offer to acquire that would have been a take-over bid for the purposes of applicable Securities Laws if not for the provisions of the Articles that cause the Multiple Voting Shares to automatically convert into Subordinate Voting Shares in certain circumstances, that offer to acquire shall nonetheless be construed to be a take-over bid for the Multiple Voting Shares for the purposes of this Agreement.

2.6 Prevention of Improper Sales

The Shareholders shall use commercially reasonable efforts to prevent any person or company from carrying out a sale (including an indirect sale) in breach of this Agreement in respect of any Multiple Voting Shares, regardless of whether that person or company is a party to this Agreement.

- 5 -

2.7 Supplemental Agreements

Without limiting any provision of this Agreement, the Shareholders shall not sell any Multiple Voting Shares unless the sale is conditional upon the person or company acquiring those shares entering into an agreement substantially in the form of this Agreement and under which that person or company has the same rights and obligations as the Shareholders have under this Agreement. Neither the conversion of Multiple Voting Shares into Subordinate Voting Shares in accordance with the provisions of the Articles nor any subsequent sale of those Subordinate Voting Shares shall constitute a sale of Multiple Voting Shares for the purposes of this Section 2.7.

2.8 Security Interest

Nothing in this Agreement shall prevent any Shareholder from time to time, directly or indirectly, from granting a bona fide security interest, by way of pledge, hypothecation or otherwise, whether directly or indirectly, in Multiple Voting Shares to any financial institution with which it deals at arm's length (within the meaning of the Income Tax Act (Canada)) in connection with a bona fide borrowing, provided that the financial institution agrees in writing to become a party to and abide by the terms of this Agreement as if such financial institution were a Shareholder as defined herein until such time as the pledge, hypothecation or other security interest has been released or the Multiple Voting Shares which were subject thereto have been sold in accordance with the terms of this Agreement.

2.9 All Sales Subject to Articles

The Shareholders and the Company hereby acknowledge that any sale of Multiple Voting Shares, whether in accordance with this Agreement or otherwise, shall in all circumstances be subject to the provisions of the Articles, including those relating to the automatic conversion of Multiple Voting Shares into Subordinate Voting Shares, and that in the event of a conflict between this Agreement and any provision of the Articles, the provisions of the Articles shall prevail.

ARTICLE 3

ACCEPTANCE OF TRUST

3.1 Acceptance and Conditions of Trust

The Trustee hereby accepts the trust created by this Agreement (the "Trust") and assumes the duties created and imposed upon it pursuant to its appointment as trustee for the SVS Holders by this Agreement, provided that:

(a) it shall not be liable for any action taken or omitted to be taken by it under or in connection with this Agreement, except for its own gross negligence, wilful misconduct or bad faith;

(b) it may employ or retain such counsel, auditors, accountants or other experts or advisers, whose qualifications give authority to any opinion or report made by them, as the Trustee may reasonably require for the purpose of determining and discharging its duties hereunder and shall not be responsible for any wilful misconduct or gross negligence on the part of any of them. The Trustee may, if it is acting in good faith, rely on the accuracy of any such opinion or report;

(c) it may, if it is acting in good faith, rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any instruction, advice, notice, opinion or other document believed by it to be genuine and to have been signed or presented by the proper party or parties and, subject to subsection 3.1(a), shall be under no liability with respect to any action taken or omitted to be taken in accordance with such instruction, advice, notice, opinion or other document;

- 6 -

(d) it shall exercise its rights under this Agreement in a manner that it considers to be in the best interests of the SVS Holders (other than the Shareholders and SVS Holders who, in the opinion of the Trustee, participated directly or indirectly in a transaction restricted by Section 2.2) and consistent with the purpose of this Agreement; and

(e) none of the provisions of this Agreement shall require the Trustee under any circumstances whatsoever to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties or the exercise of any of its rights or powers in connection with the Agreement.

In the exercise of its rights and duties hereunder, the Trustee will exercise that degree of care, diligence and skill that a reasonably prudent Trustee would exercise in comparable circumstances.

The Trustee represents that to the best of its knowledge and belief at the time of the execution and delivery hereof no material conflict of interest exists in the Trustee's role as a fiduciary hereunder and agrees that in the event of a material conflict of interest arising hereafter it will, within three months after ascertaining that it has such material conflict of interest, either eliminate the same or resign its trust hereunder. Subject to the foregoing, the Trustee, in its personal or any other capacity, may buy, lend upon and deal in securities of the Company and generally may contract with and enter into financial transactions with the Company, any of its affiliates or any of the Shareholders or any of their affiliates without being liable to account for any profit made thereby.

3.2 Enquiry by Trustee

Subject to Section 3.4, if and whenever the Trustee receives written notice from an interested party, other than SVS Holders, stating in sufficient detail that the Shareholders or the Company may have breached, or may intend to breach, any provision of this Agreement, the Trustee shall, acting on the advice of counsel, make reasonable enquiry to determine whether such a breach has occurred or is intended to occur. If the Trustee determines that a breach has occurred, or is intended to occur, the Trustee shall forthwith deliver to the Company a certificate stating that the Trustee has made such determination. Upon delivery of that certificate, the Trustee shall be entitled to take, and subject to Section 3.4 shall take, such action as the Trustee, acting upon the advice of counsel, considers necessary to enforce its rights under this Agreement on behalf of the SVS Holders.

3.3 Request by SVS Holders

Subject to Section 3.4, if and whenever SVS Holders representing not less than 10% of the then outstanding Subordinate Voting Shares determine that any one or more of the Shareholders or the Company has breached, or may intend to breach, any provision of this Agreement, such SVS Holders may require the Trustee to take action in connection with that breach or intended breach by delivering to the Trustee a requisition in writing signed in one or more counterparts by those SVS Holders and setting forth the action to be taken by the Trustee. Subject to Section 3.4, upon receipt by the Trustee of such a requisition, the Trustee shall forthwith take such action as is specified in the requisition and/or any other action that the Trustee considers necessary to enforce its rights under this Agreement on behalf of the SVS Holders.

- 7 -

3.4 Condition to Action

The obligation of the Trustee to take any action on behalf of the SVS Holders pursuant to Sections 3.2 and

3.3 shall be conditional upon the Trustee receiving from either the interested party referred to in Section 3.2, the Company or from one or more SVS Holders such funds and indemnity as the Trustee may reasonably require in respect of any costs or expenses which it may incur in connection with any such action. The Company shall provide such reasonable funds and indemnity to the Trustee if the Trustee has delivered to the Company the certificate referred to in Section 3.2.

3.5 Limitation on Action by SVS Holder

No SVS Holder shall have the right, other than through the Trustee, to institute any action or proceeding or to exercise any other remedy for the purpose of enforcing any rights arising from this Agreement unless SVS Holders shall have:

(a) requested that the Trustee act in the manner specified in Section 3.3; and

(b) provided reasonable funds and indemnity to the Trustee,

and the Trustee shall have failed to so act within thirty days after the provision of such funds and indemnity. In such case, any SVS Holder, acting on behalf of itself and all other SVS Holders, shall be entitled to take those proceedings in any court of competent jurisdiction that the Trustee might have taken.

ARTICLE 4

COMPENSATION

4.1 Fees and Expenses of the Trustee

The Company agrees to pay to the Trustee the fees set forth in Schedule "C" hereto and shall reimburse the Trustee for all reasonable expenses and disbursements including those incurred pursuant to Section 3.1(b) herein. Notwithstanding the foregoing, the Company shall have no obligation to compensate the Trustee or reimburse the Trustee for any expenses or disbursements paid, incurred or suffered by the Trustee:

(a) in connection with any action taken by the Trustee pursuant to Section 3.2 if the Trustee has not delivered to the Company the certificate referred to in Section 3.2 in respect of that action; or

(b) in any suit or litigation in which the Trustee is determined to have acted in bad faith or with gross negligence or wilful misconduct.

On all invoices issued by the Trustee for its services rendered hereunder which remain unpaid for a period of thirty days or more, interest at a rate per annum equal to the then current rate of interest charged by the Trustee to its corporate customers will be incurred, from thirty days after the issuance of the invoice until the date of payment. This Section shall survive the termination of this Agreement and the resignation or removal of the Trustee.

ARTICLE 5

INDEMNIFICATION

5.1 Indemnification of the Trustee

The Company agrees to indemnify and hold harmless the Trustee from and against all claims, losses, damages, costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel) which, without gross negligence, wilful misconduct or bad faith on the part of the Trustee, its officers, directors and employees may be paid, incurred or suffered by the Trustee by reason of or as a result of the Trustee's acceptance or administration of the Trust, its compliance with its duties set forth in this Agreement or any written or oral instructions delivered to the Trustee by the Company pursuant hereto. In no case shall the Company be liable under this indemnity for any claim against the Trustee unless the Company shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Trustee, promptly after the Trustee shall have received any such written assertion of a claim, or shall have been served with a summons or other first legal process giving information as to the nature and basis of the claim. The Company shall be entitled to participate at its own expense in the defence of the assertion or claim. The Company may elect at any time after receipt of such notice to assume the defence of any suit brought to enforce any such claim. The Trustee shall have the right to employ separate counsel in any such suit and participate in the defence thereof and the fees and expenses of such counsel shall be subject to Section 4.1 herein.

ARTICLE 6

CHANGE OF TRUSTEE

6.1 Resignation

The Trustee, or any trustee subsequently appointed, may resign at any time by giving written notice of such resignation to the Company specifying the date on which its desired resignation shall become effective, provided that such notice shall be provided at least three months in advance of such desired effective date unless the Shareholders and the Company otherwise agree. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee (which shall be a corporation or company licensed or authorized to carry on the business of a trust company in Ontario) by written instrument, in duplicate, one copy of which shall be delivered to the resigning trustee and one copy to the successor trustee. If the Company does not appoint a successor trustee, the Trustee or any SVS Holder may apply to a court of competent jurisdiction in Ontario for the appointment of a successor trustee.

6.2 Removal

The Trustee, or any trustee subsequently appointed, may be removed at any time on thirty days' prior notice by written instrument executed by the Company, in duplicate, provided that the Trustee is not at such time taking any action which it may take under Section 3.2 or 3.3 hereof. One copy of that instrument shall be delivered to the Trustee so removed and one copy to the successor trustee. The removal of the Trustee shall become effective upon the appointment of a successor trustee in accordance with Section 6.3.

6.3 Successor Trustee

Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to the Shareholders and the Company and to its predecessor trustee an instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, upon payment of any amounts then due to the predecessor trustee pursuant to the provisions of this Agreement, shall become vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as trustee in this Agreement. However, on the written request of the Shareholders and the Company or of the successor trustee, the trustee ceasing to act shall execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee, the Shareholders, the Company and such predecessor trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers.

- 9 -

6.4 Notice of Successor Trustee

Upon acceptance of appointment by a successor trustee as provided herein, the Company shall cause to be mailed notice of the succession of such trustee hereunder to the SVS Holders. If the Shareholders or the Company shall fail to cause such notice to be mailed within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Shareholders and the Company.

ARTICLE 7

TERMINATION

7.1 Term

The Trust created by this Agreement shall continue until no Multiple Voting Shares remain outstanding.

7.2 Survival of Agreement

This Agreement shall survive any termination of the Trust and shall continue until there are no Multiple Voting Shares outstanding; provided, however, that the provisions of Article 4 and Article 5 shall survive any such termination of this Agreement.

ARTICLE 8

GENERAL

8.1 Obligations of the Shareholders not Joint

The Shareholders and the Company acknowledge that federal and/or provincial legislation that addresses the protection of individuals' personal information (collectively, "Privacy Laws") applies to certain obligations and activities under this Agreement.

The Shareholders and the Company shall, prior to transferring or causing to be transferred personal information to the Trustee, obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Trustee shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Trustee agrees: (a) to have a designated chief privacy officer; (b) to maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry; (c) to use personal information solely for the purposes of providing its services under or ancillary to this Agreement and to comply with applicable laws and not to use it for any other purpose except with the consent of or direction from the other parties to this Agreement or the individual involved; (d) not to sell or otherwise improperly disclose personal information to any third party; and (e) to employ administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification.

- 10 -

8.3 Anti-Money Laundering Regulations

The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment and acting reasonably, determines that such act might cause it to be in noncompliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Trustee, in its sole judgment and acting reasonably, determine at any time that its acting under this Agreement has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days' written notice to the Company or any shorter period of time as agreed to by the Company, provided that: (a) the Trustee's written notice shall describe the circumstances of such noncompliance; and (b) if such circumstances are rectified to the Trustee's satisfaction within such 10-day period, then such resignation shall not be effective.

8.4 Third Party Interests

The other parties to this Agreement hereby represents to the Trustee that any account to be opened by, or interest to be held by, the Trustee in connection with this Agreement, for or to the credit of such party, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party, in which case such party hereto agrees to complete and execute forthwith a declaration in the Trustee's prescribed form as to the particulars of such third party.

8.5 Severability

If any provision of this Agreement is held to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remainder of this Agreement shall not in any way be affected or impaired thereby and the agreement shall be carried out as nearly as possible in accordance with its original terms and conditions.

8.6 Amendments, Modifications, etc.

This Agreement shall not be amended, and no provision thereof shall be waived, unless, prior to giving effect to such amendment or waiver, the following have been obtained: (i) the consent of the TSX and any other applicable securities regulatory authorities in Canada; and (ii) the approval of at least two-thirds of the votes cast by SVS Holders present or represented at a meeting duly called for the purpose of considering such amendment or waiver, excluding votes attached to any Subordinate Voting Shares held directly or indirectly by holders of Multiple Voting Shares, their affiliates and related parties and any persons who have an agreement to purchase Multiple Voting Shares on terms which would constitute a sale for purposes of Section 2.2, other than as permitted herein, prior to giving effect to such amendment or waiver. The provisions of this Agreement shall only come into effect contemporaneously with the listing of the Subordinate Voting Shares on the CSE and shall terminate at such time as there remain no outstanding Multiple Voting Shares.

- 11 -

8.7 Ministerial Amendments

Notwithstanding the provisions of Section 8.6, the parties to this Agreement may in writing, at any time and from time to time, without the approval of the SVS Holders but subject to the approval of the CSE, amend or modify this Agreement to cure any ambiguity or to correct or supplement any provision contained in this Agreement or in any amendment to this Agreement that may be defective or inconsistent with any other provision contained in this Agreement or that amendment, or to make such other provisions in regard to matters or questions arising under this Agreement, as shall not adversely affect the interest of the SVS Holders.

8.8 Force majeure
