FINANCIAL MATTERS

(1) General Operational Funding Principles. Except as expressly provided in this Agreement, none of the Shareholders shall be obligated to subscribe for additional Common Shares or other shares of the Corporation or to make loans to the Corporation or guarantee indebtedness or other obligations of the Corporation. It is the intention of the Parties that funds required by the Corporation from time to time will be obtained, to the extent possible, by borrowing from the Corporations' bankers or other lender acceptable to the BOD.

(2) Borrowing from Non-Arm's Length Lenders.

(a)

Notwithstanding Section 3(1), any proposed borrowing of money (the actual amount of money in any such circumstances being the "Special Loan Principal Amount") by the Company from a lender who is not Arm's Length (a "Special Approval Lender") to any of the Parties (a "Special Approval Loan") shall require the unanimous approval of all of the Directors. In the event unanimous approval is not achieved, the Directors shall cause the Company to offer in writing (the "Special Loan Offer Notice") to all Shareholders the right to lend to the Company their Pro Rata Proportion of the money contemplated by the Special Approval Loan on terms no less favourable than those proposed by the Special Approval Lender (the "Special Loan Offer"), all of which will be summarized in the Special Loan Offer Notice. The Special Loan Offer Notice will include, without limitation, a summary of the reasons for the Special Approval Loan and copy of the most recent financial statements of the Company.

(b)

Any of the Shareholders who want to accept the Special Loan Offer shall give notice of acceptance in writing to the Company within fifteen (15) Business Days from the receipt of the Special Loan Offer Notice. The Shareholders are not entitled to agree to loan any amount of the Special Approval Loan less than their respective Pro Rata Proportion of the Special Loan Principal Amount as set forth in the Special Loan Offer Notice. The failure by a Shareholder to deliver a notice of acceptance to the Corporation within the fifteen (15) Business Day period described in this Section 3(1)(b) shall be deemed to be a rejection of the Special Loan Offer. If, upon expiry of the fifteen (15) Business Day period described in this Section 3(1)(b), all or some of the Shareholders have not provided written notice that they have accepted the Special Loan Offer, the Corporation shall, to the extent of the Special Loan Amount not committed to be loaned by Shareholders (such shortfall being the "Uncommitted Special Loan Amount"), offer in writing (the

"Second Special Loan Offer Notice") to each of those Shareholders who accepted the Special Loan Offer (the "Participating Shareholders") the right to lend to the Company up to the full amount of the Uncommitted Special Loan Amount. Any of the Participating Shareholders who want to accept the Second Special Loan Offer shall give notice of acceptance in writing to the Company within five (5) Business Days from the receipt of the Second Special Loan Offer Notice and shall indicate the maximum amount they are prepared to loan. The failure by a Participating Shareholder to deliver a notice of acceptance to the Corporation within the five (5) Business Day period described above shall be deemed to be a rejection of the Second Special Loan Offer. If prior to expiry of such five (5) Business Day period, one or more of the Participating Shareholders (the "Second Offer Participating Shareholders") collectively agree to lend more than all of the Uncommitted Special Loan Amount, then the BOD shall allocate the Uncommitted Special Loan Amount in its entirety and in its discretion among the Second Offer Participating Shareholders provided that any such allocation shall not exceed any amount indicated by a Second Offer Participating Shareholder. If following the election of the Second Offer Participating Shareholders any portion of the Uncommitted Special Loan Amount remains unallocated (the "Unallocated Special Loan Amount"), then the Company shall be free to borrow the Unallocated Special Loan Amount from the Special Approval Lender on the terms summarized in the Special Loan Offer Notice and in no circumstances on terms more favourable than those set forth in the Special Loan Offer Notice.

(3) Distribution Principles.

(a)

Subject to Section 3(3)(b) below, the BOD shall, having regard to the factors enumerated below, estimate the funds arising in the ordinary course of the Company's operations during the relevant fiscal year which will be surplus to the Company's reasonable requirements and therefore available for distribution to Shareholders ("Available Distributable Funds"). In determining Available Distributable Funds, the BOD shall have regard to the Company's future growth requirements, special opportunities, existing and projected debt service and working capital requirements, the then anticipated methods of financing the foregoing and such other factors as the BOD may consider appropriate under the circumstances. In particular, the BOD may establish an appropriate reserve to fund payment of indebtedness, capital expenditure commitments and other known liabilities and obligations falling due after the fiscal year in question. Available Distributable Funds shall be distributed to the Shareholders at such times as determined by the BOD and by way of dividends or in such other manner as the BOD may determine. The BOD may at any time revise its estimate of Available Distributable Funds for a particular fiscal year and if the BOD is at any time unable to agree on estimated Available Distributable Funds, the BOD shall refer the matters in dispute to the Company's external accountants or auditors, as the case may be, for determination, which shall be binding on all Parties until such time as the

BOD or the Company's external accountants or auditors, as the case may be, make a further determination of Available Distributable Funds as contemplated herein.

(b)

Notwithstanding Section 3(3)(b), no dividends shall be declared or paid by the Company until after September 30, 2019 unless otherwise unanimously agreed by all of the members of the BOD.

(4) Executive Compensation. Base compensation for officers [*] will be frozen until [*] at those levels set forth in Schedule "D" unless otherwise unanimously agreed by all of the members of the BOD.

(5) Financial Reporting the Shareholders. During the term of this Agreement, each Shareholder shall receive from the Company, within forty-five (45) days of the end of each financial quarter in a fiscal year of the Company, unaudited financial statements for the immediately preceding quarter.

EMPLOYEE STOCK OPTION PLAN

(1) Employee Stock Option Plan. The Company shall establish an employee stock option plan (the "ESOP") for up to ten percent (10%) of the issued Shares at any given time (calculated on a fully-diluted basis) and shall initially reserve for issuance pursuant to the exercise of options granted under the ESOP two million fifty nine thousand five hundred and fifty eight (2,059,558) Shares, which options may be issued to the Company's employees, directors and officers on such terms and conditions as the BOD may determine. The option price for Shares shall be determined by the BOD in accordance with the terms of the ESOP.

PRE-EMPTIVE RIGHTS

(1) Offerings of Shares. If, and each time, the Shareholders determine in accordance with Section 2(4)(k) to issue additional securities of the Company or any subsidiary thereof, such offering shall be made in accordance with this Section 5 (the "Offering").

(2) Notice of Pre-Emptive Right. The Offering shall be made by an authorized officer of the Company sending to each Shareholder ("Notice of Pre-Emptive Right") a notice setting forth the following information:

(a)

a description of the securities to be offered (the "Treasury Shares");

(b)

the subscription price for each Treasury Share (the "Subscription Price"); and

(c)

the subscription date (the "Subscription Date"), which shall be a date not earlier than ten (10) Business Days after the date of the notice.

(3) Notice of Subscription. Each Shareholder may subscribe for his, her or its Pro Rata Proportion of the Treasury Shares determined as at the date of the Notice of Pre-emptive Right by giving notice of his subscription ("Notice of Subscription") to the Company within ten (10)

Business Days after receipt of the Notice of Pre-Emptive Right (the "Subscription Period"). A Shareholder wishing to subscribe for Treasury Shares in excess of his Pro Rata Proportion shall, in his, her or its Notice of Subscription, specify the number or dollar amount, as the case may be, of Treasury Shares in excess of his, her or its Pro Rata Proportion that he, she or it wishes to purchase.

(4) Unsubscribed Treasury Shares. If a Shareholder does not subscribe for his, her or its Pro Rata Proportion within the Subscription Period pursuant to Section 5(3) of this Agreement, the unsubscribed Treasury Shares shall be used (to the extent of the total number available) to satisfy the subscriptions of the other Shareholders pursuant to Section 5(3) of this Agreement for Treasury Shares in excess of their Pro Rata Proportions based on the Pro Rata Proportions of such Shareholders. No Shareholder shall be bound to take any Treasury Shares in excess of the amount he requested to purchase in his, her or its Notice of Subscription.

(5) Division of Treasury Shares. If the Treasury Shares of any issue are not capable, without division into fractions, of being offered to or being divided between the parties in their Pro Rata Proportions, the Treasury Shares shall be offered to or divided between the parties as nearly as may be in these proportions and any balance shall be offered to or divided between the parties in the manner determined by the Shareholders by Shareholder Resolution.

(6) Issuance of Treasury Shares. Each Shareholder subscribing for Treasury Shares shall pay for, and the Company shall issue, the Treasury Shares on the Subscription Date.

ACCESS TO INFORMATION/CONFIDENTIALITY

(1) Access. During the term of this Agreement, each Shareholder shall, one (1) time per year and upon not less than fifteen (15) Business Days' written notice given to the Company, have access to all corporate and accounting books and records in the possession of the Company, and shall be entitled to make such examination thereof at the head office of the Company.

(2) Confidentiality/Non-Disclosure. Each Shareholder shall (a) hold all of the Company's proprietary information and information concerning its business and affairs in the strictest of confidence, and (b) not make any disclosure to third parties (other than its lawyers, financial advisors and accountants) or to the public of, or use or authorize anyone to use for any purposes other than for the private affairs of the Company, any information or data relating to the operations of the Company or of any other party, except with the approval of the BOD, but this provision shall not prohibit any disclosure to the extent required by governmental or regulatory authorities. Notwithstanding the foregoing, the BOD shall be entitled to make such disclosures as the BOD, in his sole discretion, deems appropriate in connection with a potential transaction or business opportunity involving the Company, provided that the recipient of any disclosed confidential information of the Company shall sign a confidentiality agreement approved by the BOD.

RESTRICTIONS ON TRANSFERS OF SHARES

Except for sales/transfers of Shares (a) to or between family trusts or personal holding companies where the respective Shareholder remains in control of his or her Shares (each a "Permitted Assign"), and/or (b) as expressly provided for herein, no Shareholder may sell,

assign, transfer, mortgage, pledge or otherwise dispose of or otherwise encumber or grant a security interest in any Shares held or owned by the Shareholder.

VOLUNTARY TRANSFERS OF SHARES

(1)

Right of First Refusal.

If any Shareholder (in this Section 8 called the "Selling Shareholder") wishes to sell any or all of his, her or its Shares (the "Offered Shares"), the Selling Shareholder shall first deliver to all other Shareholders (in this Section 8 called "Other Shareholders") an offer in writing to sell his, her or its Offered Shares to the Other Shareholders in accordance with their Pro Rata Proportions (the "Offer"). The Offer shall be deemed to be an irrevocable offer by the Selling Shareholder to the Other Shareholders to sell all the Offered Shares to the Other Shareholders at the price per Share and upon the terms and conditions as contained in the Offer.

Any of the Other Shareholders who want to accept the Offer shall give notice of acceptance in writing to the Selling Shareholder within fifteen (15) Business Days from the receipt of the Offer. The Other Shareholders are not entitled to purchase any amount of the Offered Shares less than their respective Pro Rata Proportion of the Offered Shares as set forth in the Offer. The failure by an Other Shareholder to deliver a notice of acceptance to the Selling Shareholder within the fifteen (15)-Business Day period described in this Section 8(1) shall be deemed to be a rejection of the Offer.

If, upon expiry of the fifteen (15)-Business Day period described in this Section 8(1), all or some of the Other Shareholders have not provided written notice that they have accepted the Offer, the Selling Shareholder shall, to the extent of the Offeror's Shares not so purchased, be free to complete the sale of such Shares with an Arm's Length third party purchaser within a further period of sixty (60) days, subject to (i) the requirement that such sale be on terms no more favourable to the Arm's Length third party purchaser than the terms offered by the Selling Shareholder to the Other Shareholders as set forth in the Offer, and (ii) the condition precedent that the Arm's Length third party purchaser shall first have executed and delivered a binding adoption agreement with the other Shareholders as provided in Section 18(10).

If the Selling Shareholder does not complete the sale to the Arm's Length third party purchaser within the further sixty (60)-day period, such Shares shall again become subject to the provisions of this Section 8(1). All transfers of Shares pursuant to this Section 8(1) shall be completed on a good faith, bona fide basis.

(2)

Tag-Along Rights.

[*] If any or all of the

Other Shareholders accept the Purchase Offer, the sale of all or such percentage, in accordance with their Pro Rata Proportions, of the Shares held by such Other Shareholders, as the case may be, shall be completed at the same time as the sale of all or the same percentage, as applicable, of [*]. Each of the accepting Other Shareholders shall do all acts and things and execute such documents as may be necessary to carry out his, her or its obligations thereunder.

(3)

Drag-Along Rights.

If the Shareholders receive a bona fide cash offer (or cash equivalents) (in this Section 8(3) called a "Third Party Offer") from a person at arm's length to all of the Shareholders (in this section called a "Third Party") for all of the outstanding Shares of the Company, then unless all of the Shareholders have already agreed to accept or reject the Third Party Offer, one or more Shareholders may require all of the Shareholders to indicate in writing to the Company as to whether they are in favour or against acceptance of the Third Party Offer. A Shareholder who does not participate in the straw vote is deemed to be against acceptance. Shareholders holding collectively at least eighty percent (80%) per cent of the issued and outstanding Shares (the "Accepting Shareholders") who vote to accept the Third Party Offer may, if they wish, give a notice (the "Drag Along Notice") to the Shareholders who have not voted to accept the Third Party Offer (the "Standing Xxx Shareholders"). Delivery of the Drag Along Notice is deemed to be an offer by the Accepting Shareholders to sell all of the Shares owned by them to the Standing Xxx Shareholders at the same price per Share and on the same terms and conditions as are contained in the Third Party Offer.

The Standing Xxx Shareholders may accept the offer deemed by the Tag Along Notice within fifteen (15) Business Days following receipt of the Drag Along Notice in which case there shall be a binding agreement of purchase and sale by which the Standing Xxx Shareholders shall purchase all of the Shares owned by the Accepting Shareholders at the same price per Share and on the same terms and conditions as are contained in the Third Party Offer. The Drag Along Notice may be accepted by one or more of the Standing Xxx Shareholders, and if it is accepted by more than one, unless they otherwise agree, each of them shall purchase that number of Shares of the Accepting Shareholders pro rata to the number of shares owned by the Standing Xxx Shareholders who accept the offer in the Drag Along Notice. For greater certainty, if there is only one Standing Xxx Shareholder who delivers a Notice, such Standing Xxx Shareholder shall be required to purchase all of the Shares of the Accepting Shareholders, and if two or more Standing Xxx Shareholders accept the offer deemed by the Tag Along Notice, then they shall purchase in such proportions as they may agree or, failing agreement, pro-rata in accordance with number of Shares owned by them.

If the Standing Xxx Shareholders do not accept the offer deemed by the Tag Along Notice within the fifteen (15)-day period referred to above in this Section 8(3), then the Standing Xxx Shareholder(s) shall be deemed to have accepted the Third Party Offer and shall be required to sell all of their Shares to the Third Party in accordance with the Third Party Offer.

(4)

Permitted Transfers.

Section 8(1), Section 8(2) and Section 8(3) shall not apply in the event of a transfer of Shares owned by any Shareholder to a Permitted Assign by such Shareholder provided, however, that, as a condition precedent to being registered as a holder of any such Shares following any such transfer, the Permitted Assign shall have executed and delivered an agreement (which agreement shall not constitute a novation without the written agreement of each of the other Parties) whereby such Permitted Assign agrees to assume and be bound by all the obligations of the transferor and be subject to all the restrictions to which the transferor is subject under the terms of this Agreement; and in the case of a Permitted Assign which is a corporation, to retransfer such Shares to the transferor if such corporation shall cease to qualify as a Permitted Assign. Each of the Shareholders agrees that, if the Shares beneficially owned by such Shareholder are transferred to a Permitted Assign of such Shareholder, such Shareholder shall remain bound by the provisions of this Agreement; shall ensure that such Permitted Assign shall continue to qualify as a Permitted Assign for so long as the Permitted Assign beneficially owns, directly or indirectly, such Shares; and shall guarantee to the other Shareholders the performance by the Permitted Assign of all of the obligations of such Permitted Assign under the agreement to be entered into by such Permitted Assign as referred to in this Section 8(4).

MANDATORY TRANSFERS OF SHARES

If any Shareholder suffers an Event of Insolvency or commits an Event of Default (in this Section 9 called a "Defaulting Shareholder"), such Defaulting Shareholder or his, her or its legal or personal representatives, as the case may be, shall offer to sell all of the Defaulting Shareholder's Shares to the other Shareholders in accordance with their Pro Rata Proportions for a purchase price equal to the Fair Market Value of such Shares. Each of the other Shareholders may then, in his, her or its sole discretion, decide, but is not obliged, to purchase such Defaulting Shareholder's Shares in accordance with their Pro Rata Proportions. In the event that a Shareholder does not purchase a portion of the Defaulting Shareholder's Shares in accordance with his, her or its Pro Rata Proportions pursuant to this Section 9, then the remaining Shareholders may then, in their sole discretion, decide, but are not obliged, to purchase such outstanding Shares of the Defaulting Shareholder in accordance with their Pro Rata Proportions.

10.

THE FAIR MARKET VALUE OF SHARES

The Shareholders shall select by Shareholder Resolution an independent business valuator who is (a) a member of the Canadian Institute of Chartered Business Valuators, and (b) knowledgeable in the industry(ies) of which the Company is then part. The valuator so selected shall determine the fair market value of each Share (excluding any possible minority discount) based on such factors as such valuator deems professionally appropriate or necessary.
