(a) the Financial Advisor has rendered its opinion to the Board to the effect that, as of the date of such opinion, and subject to the assumptions, limitations, qualifications and other matters considered in connection with the preparation of such opinion, and treating the conversion of the Common Shares into the Amalco Redeemable Shares pursuant to the Amalgamation and the subsequent redemption for cash of such Amalco Redeemable Shares by Amalco as a single, unitary transaction, the cash redemption consideration to be received by the holders of Common Shares (other than the Excluded Shareholders) upon the redemption of the Amalco Redeemable Shares to be issued to the holders of Common Shares (other than the Excluded Shareholders) upon conversion of the Common Shares pursuant to the Amalgamation is fair from a financial point of view to such holders of Common Shares (other than the Excluded Shareholders); it being understood that, for purposes of such opinion, the term "Excluded Shareholders" means the Interested Shareholder and those holders of Common Shares that elect to receive the Cash and Note Option (the "Fairness Opinion");

(b) the Board, following the receipt and review of recommendations from the Special Committee, has determined (with ▇▇. ▇▇▇▇▇▇▇ as an interested director abstaining) that the Amalgamation is fair to the Shareholders (other than the Excluded Shareholders) and is in the best interests of Opta Minerals, and accordingly has approved (with ▇▇. ▇▇▇▇▇▇▇ as an interested director abstaining) the entering into of this Agreement and the Amalgamation Agreement, and the making of a recommendation that Shareholders vote all of their Common Shares in favour of the Amalgamation Resolution (collectively, the "Board Approval"); and

(c) each member of the Board (other than ▇▇. ▇▇▇▇▇▇) and each officer of Opta Minerals has advised Opta Minerals that he intends to vote all Common Shares held by him in favour of the Amalgamation Resolution and that the press release announcing the Amalgamation may so reference such statement of intention and references to such intention may be made in the Circular.

The Acquiror (or the Acquiror Parent on behalf of the Acquiror) shall, no later than the Effective Date, provide the Depositary with sufficient funds and Subordinated Notes in escrow (the terms and conditions of such escrow to be satisfactory to the Parties, acting reasonably) to pay in full: (i) the aggregate Share Consideration (for the redemption of all of the Amalco Redeemable Shares issued pursuant to the Amalgamation to the holders of the Common Shares (other than, for greater certainty, the Common Shares held by the Interested Shareholder which will be transferred to the Acquiror Parent and then to the Acquiror prior to the Amalgamation as indicated in the Recitals to this Agreement, and will then be cancelled pursuant to the Amalgamation, all as set forth more particularly in the Amalgamation Agreement)), and (ii) the Option Consideration.

-17-

2.7 U.S. Restrictions on Consideration

The Amalco Redeemable Shares and the Subordinated Notes will be “restricted securities” (as such term is defined in Rule 144(a)(3) under the U.S. Securities Act) to the same extent and proportion that the Common Shares were “restricted securities” prior to the Effective Date.

7.3 Responding to Acquisition Proposals and Superior Proposals

(a) Notwithstanding Section 7.1(a) or any other provision of this Agreement, if at any time following the occurrence of a Specified Lock-Up Termination Event and prior to obtaining the Shareholder Approval, Opta Minerals or any of its Representatives receives a bona fide written Acquisition Proposal and such Acquisition Proposal was not solicited after the date hereof in contravention of Section 7.1(a) and did not otherwise result from a contravention of Section 7.1(a), then Opta Minerals may:

-29-

(i) contact the person making such Acquisition Proposal and its representatives for the sole purpose of clarifying the terms and conditions of such Acquisition Proposal and the likelihood of its consummation so as to determine whether such Acquisition Proposal is, or would reasonably be expected to lead to, a Superior Proposal; and

(ii) if the Board first determines in good faith, after consultation with its financial advisors, outside legal counsel and the Special Committee, that such Acquisition Proposal is, or would reasonably be expected to lead to, a Superior Proposal and the failure to provide the person making such Acquisition Proposal with access to such information would be inconsistent with the fiduciary duties of the Board: (A) provide the person making such Acquisition Proposal and its Representatives with access to information regarding Opta Minerals for a period of not more than seven (7) Business Days (the "Diligence Period"); and (B) engage in discussions and negotiations with respect to the Acquisition Proposal with the person making such Acquisition Proposal and its Representatives; provided that (x) Opta Minerals first enters into an Acceptable Confidentiality Agreement with such person, (y) Opta Minerals provides a copy of such Acceptable Confidentiality Agreement to the Acquiror Parent and the Acquiror promptly following its execution and the Acquiror Parent and the Acquiror are promptly provided (to the extent not previously provided) with all information provided to such person (which requirement may be satisfied by posting such information to Opta Minerals’ electronic data room at ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇ – Project Wedge), and (z) as of the expiry of the Diligence Period, unless such person has made a Superior Proposal, Opta Minerals shall request the return or destruction of all information provided to such person pursuant to such Acceptable Confidentiality Agreement and use commercially reasonable efforts to ensure that such requests are honoured.

(b) Notwithstanding Section 7.1(a) or any other provision of this Agreement, Opta Minerals may at any time following the occurrence of a Specified Lock-Up Termination Event and prior to obtaining the Shareholder Approval (A) enter into an agreement (other than an Acceptable Confidentiality Agreement contemplated by Section 7.3(a)(ii)) with respect to an Acquisition Proposal that is a Superior Proposal and/or (B) withdraw, modify or qualify its approval or recommendation of the Amalgamation and recommend or approve an Acquisition Proposal that is a Superior Proposal, provided:

(i) the person making the Superior Proposal was not restricted from making such Superior Proposal pursuant to an existing standstill or similar restriction;

(ii) Opta Minerals shall have at all times been, and continue to be, in compliance with its obligations under this Article 7;

(iii) the Board has determined, after consultation with its outside legal counsel and financial advisors and the Special Committee, that such Acquisition Proposal is a Superior Proposal and that the failure to take the relevant action would be inconsistent with its fiduciary duties;

-30-

(iv) Opta Minerals has delivered written notice to the Acquiror Parent and the Acquiror (A) of the determination of the Board that the Acquisition Proposal is a Superior Proposal, (B) of the intention of the Board to approve or recommend such Superior Proposal and/or of Opta Minerals to enter into an agreement with respect to such Superior Proposal, together with a copy of such proposed agreement to be executed by the person making such Superior Proposal and (C) providing a summary of the valuation analysis attributed by the Board in good faith to any non-cash consideration included in such Acquisition Proposal after consultation with its financial advisors (the "Superior Proposal Notice");

(v) at least five (5) Business Days have elapsed since the date the Superior Proposal Notice was received by the Acquiror Parent and the Acquiror, which five (5) Business Day period is referred to as the "Match Period" (for greater certainty, the Match Period shall expire at 5:00 p.m. (Toronto time) on the fifth (5^th) Business Day following the day that the Superior Proposal Notice was delivered to the Acquiror Parent and the Acquiror;

(vi) if the Acquiror Parent and the Acquiror have offered to amend the terms of the Amalgamation and this Agreement during the Match Period pursuant to Section 7.3(c), the Board has determined in good faith, after consultation with Opta Mineral's outside legal counsel and financial advisers, that such Acquisition Proposal continues to be a Superior Proposal compared to the terms of the Amalgamation and this Agreement as proposed to be amended by the Acquiror Parent and the Acquiror at the termination of the Match Period;

(vii) such Superior Proposal does not require Opta Minerals or any other person to seek to interfere with the attempted successful completion of the Amalgamation (including requiring Opta Minerals to delay, adjourn, postpone or cancel the Meeting) or provide for the payment of any break, termination or other fees or expenses or confer any rights or options to acquire assets or securities of Opta Minerals or any of its Subsidiaries to any person in the event that Opta Minerals completes the Amalgamation or any other similar transaction with the Acquiror Parent or the Acquiror agreed to prior to the termination of this Agreement; and

(viii) prior to, or concurrently with, entering into such definitive agreement, Opta Minerals pays the Termination Payment to the Acquiror.

(c) Opta Minerals acknowledges and agrees that, during the Match Period, or such longer period as Opta Minerals may approve for such purpose, the Acquiror Parent and the Acquiror shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement and the Amalgamation and Opta Minerals shall co-operate with the Acquiror Parent and the Acquiror with respect thereto, including negotiating in good faith with the Acquiror Parent and the Acquiror to enable the Acquiror to make such adjustments to the terms and conditions of this Agreement and the Amalgamation as Acquiror deems appropriate and as would enable the Acquiror to proceed with the Amalgamation on such adjusted terms. The Board will review any proposal by the Acquiror Parent and the Acquiror to amend the terms of the Amalgamation in order to determine, in good faith in the exercise of its fiduciary duties, whether the Acquiror’s proposal to amend the Amalgamation would result in the Acquisition Proposal not being a Superior Proposal compared to the proposed amendment to the terms of the Amalgamation. If the Board determines that the Acquisition Proposal would cease to be a Superior Proposal, Opta Minerals shall promptly so advise the Acquiror Parent and the Acquiror and Opta Minerals and the Acquiror Parent and the Acquiror shall amend this Agreement to reflect such offer made by the Acquiror, and shall take and cause to be taken all such actions as are necessary to give effect to the foregoing.

-31-

(d) The Board shall promptly (and in any event no later than three (3) Business Days following a request to that effect from the Acquiror Parent or the Acquiror) reaffirm its recommendation of the Amalgamation by press release after: (i) any Acquisition Proposal (which the Board determines not to be a Superior Proposal) is publicly announced or made or (ii) the Board determines that a proposed amendment to the terms of the Amalgamation and this Agreement would result in the Acquisition Proposal not being a Superior Proposal, and the Acquiror Parent and the Acquiror have so amended the terms of the Amalgamation. Opta Minerals shall provide the Acquiror Parent and the Acquiror and their legal advisor with a reasonable opportunity to review and comment on the form and content of any such press release, and shall make all reasonable amendments to such press release as requested by the Acquiror Parent, the Acquiror and their counsel.

(e) Nothing in this Agreement shall prevent the Board from responding through a directors’ circular or otherwise as required by Securities Laws to an Acquisition Proposal that it determines is not a Superior Proposal. Further, nothing in this Agreement shall prevent the Board from making any disclosure to the Securityholders if the Board, acting in good faith and upon the advice of its outside legal counsel, shall have first determined that the failure to make such disclosure would be inconsistent with the fiduciary duties of the Board and provided further that such disclosure is otherwise in accordance with the terms of this Agreement. The Acquiror Parent, the Acquiror and their counsel shall be given a reasonable opportunity to review and comment on the form and content of any such directors’ circular, recognizing that whether or not such comments are appropriate will be determined by Opta Minerals, acting reasonably.

(f) Each successive material modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of Section 7.3(b) and shall require a new five (5) Business Day Match Period from the date described in Section 7.3(b)(v).

(g) If no Specified Lock-up Termination Event shall have occurred and at any time prior to obtaining the Shareholder Approval, Opta Minerals receives a Superior Proposal, the Board may, notwithstanding Section 7.1(a)(iii), make a Change in Recommendation if and only if Opta Minerals shall have at all times been and continues to be, in compliance with its obligations under Article 7, provided, for greater certainty, that Opta Minerals shall not have the right to terminate this Agreement as a result of such Superior Proposal unless the terms and conditions applicable to such a termination set forth in Section 7.3 have been complied with and satisfied.

(iii) any Governmental Entity shall have enacted any Law or issued an order, decree or ruling permanently restraining or enjoining or otherwise prohibiting any of the transactions contemplated herein (unless such law, order, decree or ruling has been withdrawn, reversed or otherwise made inapplicable) which order, decree or ruling is final and non-appealable;

(c) Opta Minerals, if:

9.3 Termination Payment

(a) The Acquiror shall be entitled to a payment of $1,000,000 (the "Termination Payment") upon the occurrence of any of the following events (each a "Termination Payment Event") which shall be paid by Opta Minerals within the time specified in respect of such Termination Payment Event:

(i) this Agreement is terminated by the Acquiror pursuant to Section 9.2(d)(iii), provided that neither the Acquiror Parent nor the Acquiror is in breach of the Support Agreements, in which case the Termination Payment shall be paid to the Acquiror by 1:00 p.m. (Toronto time) on the first Business Day following termination;

(ii) this Agreement is terminated by the Acquiror pursuant to Section 9.2(d)(iv), provided that neither the Acquiror Parent nor the Acquiror is in breach of the Support Agreements, in which case the Termination Payment shall be paid to the Acquiror by 1:00 p.m. (Toronto time) on the first Business Day following termination;

(A) prior to the termination of the Agreement, a bona fide Acquisition Proposal has been made or publicly announced, or any Person other than the Acquiror Parent, the Acquiror or their affiliates has publicly announced an intention to do so; and

(B) within twelve (12) months following the date of the termination of this Agreement, a definitive agreement is entered into with respect to an Acquisition Proposal (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to in clause (A) above), and such Acquisition Proposal is subsequently completed; and

(C) for purposes of this paragraph (iv), the term “Acquisition Proposal” will have the meaning assigned to such term in Section 1.1, except that references to “20% or more” will be deemed to be references to “50% or more”.

-37-

(b) The Termination Payment shall be paid by Opta Minerals to the Acquiror by wire transfer in immediately available funds to an account specified by the Acquiror. For greater certainty, the obligations of Opta Minerals under this Section 9.3 shall survive the termination of this Agreement, regardless of the circumstances thereof.

(c) Opta Minerals acknowledges that the amount set out in this Section 9.3 in respect of the Termination Payment represents liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, which the Acquiror will suffer or incur as a result of the event giving rise to such damages and resultant termination of this Agreement, and is not a penalty. Opta Minerals irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive.

(d) For greater certainty, Opta Minerals shall not be obligated to make more than one payment under this Section 9.3 if one or more of the events specified therein occurs.

9.4 Effect of Termination

Where a Termination Payment Event occurs, the Termination Payment to be received pursuant to Section 9.3 in consideration for the disposition by the Acquiror Parent and the Acquiror of their rights under this Agreement (other than the rights that survive termination of this Agreement set out in this Section 9.4) is the sole remedy in compensation or damages of Opta Minerals with respect to the event or events giving rise to the termination of this Agreement and the resulting Termination Payment Event; provided, however, that nothing contained in this Section 9.4, and no payment of any Termination Payment, shall relieve or have the effect of relieving any Party in any way from liability for damages incurred or suffered by a Party as a result of an intentional or wilful breach of this Agreement. In the event of termination of this Agreement pursuant to Section 9.2, this Agreement shall be of no further force and effect, except that Section 9.3, this Section 9.4 and Article 10 shall survive the termination of this Agreement.

9.5 Remedies

Subject to Section 9.4, the Parties acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any Party or its Representatives and any such breach would cause the non-breaching Party irreparable harm. Accordingly, the Parties agree that, in the event of any breach or threatened breach of this Agreement by one of the Parties, the non-breaching Party will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance and the Parties shall not object to the granting of injunctive or other equitable relief on the basis that there exists an adequate remedy at Law. Such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at Law or equity to each of the Parties.

9.6 Expenses

Except as otherwise provided herein, all fees, costs and expenses incurred in connection with this Agreement and the Amalgamation shall be paid by the Party incurring such fees, costs or expenses (including, in the case of Opta Minerals, those fees, costs and expenses referred to in the definition of Estimated Transaction Costs in Section 1.1).

TERMS OF SUBORDINATED NOTES

Issuer:		Opta Minerals Inc. (the “Corporation”), a corporation existing under the laws of Canada (and, for greater certainty, being the corporation that will result from the Amalgamation (as hereinafter defined)).
Issue:		Unsecured promissory notes of the Corporation (the “Notes”) in an aggregate principal amount of up to C$2,958,067 to be issued in connection with the Acquisition (as hereinafter defined).
Description of Acquisition:		It is proposed that the Corporation will enter into an acquisition agreement (the “Acquisition Agreement”) with Speyside Equity Fund I LP (“Speyside”), Wedge Acquisition Holdings Inc., an affiliate of Speyside (“Acquiror Parent”), and Wedge Acquisition Inc., a wholly-owned subsidiary of Acquiror Parent (“Acquiror”), pursuant to which Acquiror will acquire (the “Acquisition”) all of the issued and outstanding common shares of the Corporation (the “Common Shares”), other than those Common Shares held by certain current shareholders of the Corporation who will exchange their Common Shares for shares of Acquiror Parent prior to the completion of the Acquisition, by way of amalgamation of Acquiror and the Corporation (the “Amalgamation”) under Section 181 of the Canada Business Corporations Act. Pursuant to the terms of the Acquisition Agreement, the consideration payable to the shareholders of the Corporation for their Common Shares will consist of, at the election of each shareholder: (i) approximately C$0.5202 per Common Share payable entirely in cash (the “Cash Only Option”); or (ii) approximately C$0.3526 per Common Share payable in cash and a Note in a principal amount of approximately C$0.1676 per Common Share (the “Cash and Note Option”), subject to adjustment in accordance with the terms of the Acquisition Agreement. The Notes shall be issued effective as of the date of completion of the Amalgamation (the “Issue Date”). SunOpta Inc. (“SunOpta”) has irrevocably agreed with Acquiror Parent and Acquiror that it will elect to accept the Cash and Note Option.
Interest Rate:		Simple interest at the rate of 2% per annum accruing from the Issue Date (as hereinafter defined) computed on the basis of a 360-day year composed of twelve 30-day months, with pro-rata payments being made for any partial months.  Interest shall be payable in cash on the earlier of: (i) the Maturity Date (as hereinafter defined); and (ii) the date on which all principal outstanding under the Notes is repaid.  Interest shall be payable at the same rate on overdue interest.
Maturity Date:		Thirty (30) months following the Issue Date (the “Maturity Date”).

Subordination and Postponement:		The Notes will (i) be direct obligations of the Corporation; (ii) not be guaranteed by any subsidiary of the Corporation, (iii) not be secured by any mortgage or pledge of or charge over any of the property, assets or undertaking of the Corporation or any of its subsidiaries, (iv) will be subordinate to the Senior Indebtedness in all respects; and (v) subject only to any Mandatory Prepayments described below, will be postponed to repayment of all Senior Indebtedness (as hereinafter defined). “Senior Indebtedness” means all indebtedness of the Corporation under that certain Second Amended and Restated Credit Agreement dated as of May 18, 2012 between the Corporation, as borrower, the parties named therein from time to time as guarantors, The Bank of Nova Scotia, as administrative agent (the “Senior Indebtedness Agent”), and the Lenders, as lenders (as same may be amended, restated, supplemented or otherwise modified from time to time) (the “Credit Agreement”). If the holder of any Note receives any payment from the Corporation under the Note in contravention of the terms of the Notes which provide that the Notes shall be subordinated to the Senior Indebtedness and postponed to repayment of all Senior Indebtedness, such payment shall be held in trust for and promptly paid by the holder to the Senior Indebtedness Agent. The Notes will not restrict the Corporation from incurring additional indebtedness or from mortgaging, pledging or charging its property or assets to secure any other indebtedness of the Corporation.
Optional Prepayment:		Subject to prior approval of the Corporation’s principal lenders under the Senior Indebtedness to the extent that the terms of the Senior Indebtedness require such approval, the outstanding principal amount of some or all of the Notes (the “Principal Amount”) and all accrued and unpaid interest thereon may be prepaid, in whole or in part, by the Corporation at any time without penalty or premium.
Mandatory Prepayments:		The Corporation shall repay amounts owing under the Notes including any accrued interest thereon (collectively, the “Note Indebtedness”) on a quarterly basis commencing first quarter of 2016 as follows: (a)   if the ratio of Senior Indebtedness to EBITDA of the Corporation for the prior four quarters on a rolling basis is less than or equal to 2.75:1, then the Corporation shall repay C$150,000 on the last day of the current fiscal quarter; and (b)   if the ratio of Senior Indebtedness to EBITDA of the Corporation for the prior four quarters on a rolling basis is greater than 2.75:1 but less than or equal to 3.25:1, then the Corporation shall repay C$50,000 on the last day of the current fiscal quarter; and (c)   if the ratio of Senior Indebtedness to EBITDA of the Corporation for the prior four quarters on a rolling basis is greater than 3.25:1, then the Corporation shall not be obligated to repay any Note Indebtedness on the last day of the current fiscal quarter.

In addition, within five (5) days of any Change of Control, the Corporation shall repay all Note Indebtedness then outstanding.

All Mandatory Prepayments of Note Indebtedness shall be applied first against the principal amount then outstanding and any surplus shall be applied against the interest then accrued and outstanding.

For purposes any such Mandatory Repayments:

“EBITDA” means for any relevant period, an amount equal to the Corporation’s net income or net loss for the period, calculated on a consolidated basis;

(a) plus, amounts deducted in calculating net income or net loss in respect of depreciation and amortization;

(b) plus, total interest expense;

(c) plus, amounts deducted in calculating net income or net loss in respect of income taxes, whether or not deferred;

and excluding:

(d) any gain or loss attributable to the sale, conversion or other disposition of property; and

(e) gains resulting from the write up of property and losses resulting from the write down of property (other than allowances for doubtful accounts receivable); and

(f) any gain or loss on the repurchase or redemption of any securities (including in connection with the early retirement or defeasance of any debt); and

(g) any unrealized, foreign currency translation gains or losses; and

(h) all non-cash gains, non-cash losses or other non-cash amounts that were included in such net income; and

(i) any amount included in net income to which any other person is entitled;

all of which shall be calculated in accordance with generally accepted accounting principles unless otherwise expressly described. Unless otherwise provided, EBITDA shall be calculated on a rolling four quarter basis. Furthermore and notwithstanding the foregoing definition of EBITDA: (i) to the extent that any amendments or add backs are made in the future to the definition for purposes of calculating EBITDA pursuant to Credit Agreement in respect of the Senior Indebtedness, the definition of EBITDA for purposes of the Mandatory Prepayments under the Notes shall be similarly amended, and (ii) the treatment of any expense as an extraordinary, unusual or non-recurring item under GAAP for the purposes of EBITDA under the Note shall treated in the same manner as under the Credit Agreement.

		“Change of Control” means, other than the Amalgamation, (A) any consolidation or merger of the Corporation with or into any other corporation or other entity or person, or any other amalgamation, arrangement, corporate reorganization, other than any such amalgamation, arrangement, consolidation, merger or reorganization in which the voting shares of the Corporation immediately prior to such consolidation, merger or reorganization, continue to represent a majority of the voting power of the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such amalgamation, arrangement, consolidation, merger or reorganization; or (B) any transaction or series of related transactions to which the Corporation is a party in which in excess of 50% of the voting rights attached to the Corporation’s securities is transferred (provided, however, that any such transfer to an affiliate of the Acquiror Parent or to a fund managed by an affiliate of the general partner of Speyside shall not constitute a Change of Control).
Non-Transferability:		The Notes may not be transferred other than a transfer of all but not less than all of the Notes held by a holder to such holder’s, direct or indirect,  wholly-owned subsidiary. A holder of Notes must give prior written notice to the Corporation of any such transfer.
Financial Information:		For so long as any Note Indebtedness remains outstanding, the Corporation shall deliver to each holder of Notes: (a)          as soon as practicable, but in any event within 120 days after the end of each fiscal year of the Corporation audited financial statements of the Corporation for and as at the end of such fiscal year; and (b)          as soon as practicable, but in any event within 60 days after the end of each of the first three quarters, unaudited quarterly financial statements.
Inspection Rights:		For so long as any Note Indebtedness remains outstanding, the Corporation shall permit a representative of the holders of the Notes to examine its accounts and records and discuss the Corporation’s affairs, finances and accounts with its officers, during normal business hours of the Corporation as may be reasonably requested; provided, however, that the Corporation shall not be obligated to provide access to any information that it reasonably and in good faith considers to be confidential information (unless covered by an enforceable confidentiality agreement, in form acceptable to the Corporation).
Currency:		All amounts under the Notes shall be denominated and paid in Canadian dollars.

Default:		Normal events of default for subordinated promissory notes, including: (a) failure to pay principal or premium, if any, on the Notes when due, whether at maturity, by declaration or otherwise; (b) certain events of bankruptcy, insolvency or reorganization of the Corporation under bankruptcy or insolvency laws; or (c) default in the observance or performance of any material covenant or condition of the Notes and continuance of such default for a period of 30 days after notice in writing has been given under terms of the Notes to the Corporation specifying such default and requiring the Corporation to rectify the same; or (d) any default under the Credit Agreement. Upon default by the Corporation in payment of any amount owing under the Notes, the principal sum then outstanding plus all accrued and unpaid interest shall, at the option of the holder of the Note, become immediately due and payable without demand or notice.
Modifications and Waivers:		The rights of the holders of Notes may in certain circumstances be modified and/or events of default under the Notes may be waived by way of an Extraordinary Resolution which shall be binding upon all holders of Notes. “Extraordinary Resolution” will be defined, in effect, as a resolution passed at a meeting of holders of Notes by the affirmative votes of the holders of at least 66 2/3% of the principal amount of Notes voted on the resolution at a meeting of holders at which a quorum, as set forth below, is present or as one or more instruments in writing signed by the holders of at least 66 2/3% in principal amount of all outstanding Notes. Holders of at least 50% in principal amount of the outstanding Notes will constitute a quorum for a meeting of holders with respect to an Extraordinary Resolution. In the absence of a quorum, the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting. Not less than five days' notice shall be given of the time and place of such adjourned meeting. At the adjourned meeting, the holders of Notes present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally called.
Governing Law:		All documentation in connection with the Notes shall be governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein.
