ARTICLE 2 PURCHASE AND SALE

Section 2.1

Purchase and Sale

On the Closing Date, the Vendor shall sell and the Purchaser shall purchase, the Purchased Shares upon and subject to the terms and conditions of this Agreement for a purchase price (the “Purchase Price”) equal to ONE BILLION ONE-HUNDRED TWENTY-FIVE MILLION DOLLARS ($1,125,000,000), subject to adjustment as set out in this Agreement, including in accordance with Section 2.5 and Section 2.6.

Section 2.2

Payment

Except as provided below, the Purchase Price payable, without any deduction or withholding whatsoever, on the Closing Date shall be paid and satisfied by the Purchaser by wire transfer to the order of the Vendor in immediately available funds.

Section 2.3

Closing Financial Statements

Not later than 90 days after the Closing Date, the Vendor will prepare and deliver the Closing Financial Statements which include the balance sheet and statement of income and loss and calculation of the Net Working Capital, in each case as at the Effective Closing Time, to the Purchaser. The Closing Financial Statements will be prepared on a basis consistent with the Annual Financial Statements and the Interim Financial Statements, save and except the Closing Financial Statements will be unaudited and consequently will not contain notes. In each case the Purchaser will make available to the Vendor the Books and Records and the services of the officers, employees and other personnel of the Corporations who participated in the preparation of the Annual Financial Statements, the Interim Financial Statements and the Net Working Capital calculation. The Vendor will make available to the Purchaser copies of all working papers, books and records and personnel used in the preparation of the Closing Financial Statements and the Net Working Capital calculation, together with such other information relating thereto as the Purchaser may reasonably request. The Purchaser may notify the Vendor that it accepts or disputes the Closing Financial Statements and the calculation of the Net Working Capital at any time within 30 days after receiving them, but will be deemed to accept them on the 31st day after receipt thereof unless the Purchaser delivers a written notice (the

- 22 -

“Dispute Notice”) to the Vendor of a dispute (a “Closing Financial Statements Dispute”) prior to that 31st day. On the date of the Purchaser’s deemed acceptance, or any earlier date upon which the Vendor receives notice of the Purchaser’s acceptance, the Closing Financial Statements and the calculation of Net Working Capital, will be conclusive and binding on the Purchaser and the Vendor.

Section 2.4

Disputes

The Dispute Notice must set out the reasons for the Closing Financial Statements Dispute, the amounts in dispute, and reasonable details of the calculation of those amounts. The Purchaser and the Vendor will attempt, in good faith, to resolve the Closing Financial Statements Dispute within 10 days after the Vendor’s receipt of the Dispute Notice. Any Closing Financial Statements Dispute not resolved by the Purchaser and the Vendor within that period will be submitted to a senior partner of the accounting firm of Deloitte & Touche LLP (the “Selected Accountant”), who will resolve the Closing Financial Statements Dispute acting as an expert, and not an arbitrator. The resolution of the Closing Financial Statements Dispute will be final and binding upon the Purchaser and the Vendor, with no right of appeal or judicial review on any grounds. The fees, costs and expenses of the Selected Accountant in resolving the Closing Financial Statements Dispute shall be borne as follows: (a) if the Selected Accountant makes a determination, in the aggregate, in favour of the Purchaser with respect to the issues raised in the Dispute Notice, the fees and expenses shall be borne by the Vendor; and (b) if the Selected Accountant makes a determination, in the aggregate, in favour of the Vendor with respect to the issues raised in the Dispute Notice, the fees and expenses shall be borne by the Purchaser. Any amounts in the Closing Financial Statements not disputed in the Dispute Notice will be deemed accepted by Purchaser, and Purchaser will not be permitted to raise any such amounts in connection with the foregoing dispute resolution procedure, subject to the recognition that amounts not disputed may incur adjustments in connection with the resolution of amounts included in the Dispute Notice to the extent they are mathematical functions of or mathematically dependent on the disputed amounts.

Section 2.5

(b)

if the Non-Inventory Working Capital is less than the Non-Inventory Working Capital Target, (i) the Purchase Price will be decreased by the amount of that difference, and (ii) the Vendor will pay the amount of that decrease to the Purchase Price to the Purchaser within three (3) Business Days.

- 23 -

(2) Materials Supplies & Packaging and Additives Inventory Adjustment

(a)

if the value of the Materials Supplies & Packaging and Additives Inventory calculated in accordance with the Working Capital Protocol is greater than the Materials Supplies & Packaging and Additives Inventory Target, (i) the Purchase Price will be increased by the amount of that excess, and (ii) the Purchaser will pay the amount of that increase to the Purchase Price to the Vendor within three (3) Business Days; and

(b)

if the value of the Materials Supplies & Packaging and Additives Inventory calculated in accordance with the Working Capital Protocol is less than the Materials Supplies & Packaging and Additives Inventory Target, (i) the Purchase Price will be decreased by the amount of that difference, and (ii) the Vendor will pay the amount of that decrease to the Purchase Price to the Purchaser within three (3) Business Days.

(3) Hydrocarbon Inventory Adjustment

(a)

if the Hydrocarbon Inventory Value calculated in accordance with the Working Capital Protocol is greater than the Hydrocarbon Inventory Target: (i) the Purchase Price will be increased by the value of the amount of that excess, and (ii) the Purchaser will pay the amount of that increase to the Purchase Price to the Vendor within three (3) Business Days; and

(b)

if the Hydrocarbon Inventory Value calculated on the basis of the Closing Financial Statements and in accordance with the Working Capital Protocol is less than the Hydrocarbon Inventory Target, (i) the Purchase Price will be decreased by the amount of that difference, and (ii) the Vendor will pay the amount of that decrease to the Purchase Price to the Purchaser within three (3) Business Days.

Section 2.6

Any payment made by the Vendor to any of the Purchaser Indemnified Parties pursuant to Article 7 will constitute a reduction to the Purchase Price.

(a)

cooperating with each other in connection with the filings required to obtain each Regulatory Approval, and consulting with each other in relation to each step of the procedure before the relevant Governmental Authorities and as to the contents of all communications with such Governmental Authorities. In particular, to the extent permitted by Applicable Law or Governmental Authority, no Party will make any submission, filing, notification, or communication in relation to the transactions contemplated hereunder without first providing the other Party with a copy of such notification in draft form (subject to reasonable redactions or limiting such draft, or parts thereof, on an outside-counsel-only basis where appropriate) and giving such other Parties a reasonable opportunity to discuss its content before it is filed with the relevant Governmental Authorities, and such first Party will consider in good faith all reasonable comments timely made by the other Parties in this respect;

(b)

furnishing to the other Parties (on an outside-counsel-only basis where appropriate) all information within its possession that is reasonably required for obtaining the Regulatory Approvals; provided, however, that (i) no such information will be required to be provided by a party if it determines, acting reasonably, that the provision of such information would jeopardize any solicitor-client, attorney-client, work product or other legal privilege or that such information is material and competitively sensitive (it being understood, however, that the Parties will cooperate in any reasonable requests that would enable an otherwise required production to occur without so jeopardizing privilege or jeopardizing the confidentiality of any such material and competitively sensitive information) and (ii) in any such case the Parties will cooperate with a view to establishing a mutually satisfactory procedure for providing such information, and the relevant party required to provide such information will provide it directly to such Governmental Authority requiring or requesting such information;

For greater certainty, comments provided by the Vendor need not be accepted by the Purchaser.

(7) Reverse Termination Fee.

(a)

In the event that the Agreement is terminated pursuant to Section 10.2(c) (Occurrence of Outside Date) due to the fact that the condition set forth in Section 6.3(1) (Required Regulatory Approvals) is otherwise not satisfied by the Outside Date, the Purchaser shall pay SIXTY MILLION DOLLARS ($60,000,000) (the “Reverse Termination Fee”) to the Vendor within two (2) Business Days of the occurrence of such termination.

(b)

The Parties acknowledge and agree that because of the unique nature of the subject matter hereof, it is difficult or impossible to determine with precision the actual economic impact as a result of the failure of the Purchaser to satisfy its obligations under this Section 5.3 or any other circumstances giving rise to the obligation of the Purchaser to pay to the Vendor the Reverse Termination Fee. As such, any sums payable under this Section 5.3(7)(b) shall constitute minimum liquidated damages (whether or not expressly stated to be so) and have been agreed to as a genuine, fair and reasonable estimate of the minimum actual damages that will be suffered in the circumstances giving rise thereto. The Purchaser agrees that the amounts of such minimum liquidated damages shall be due and payable to the Vendor regardless of the actual economic impact caused by the circumstances giving rise to the obligation of the Purchaser to pay to the Vendor the Reverse Termination Fee. The Parties agree to waive their right to seek a declaration, judgment or order from a court of competent jurisdiction or other dispute resolution body that this Section 5.3(7)(b) is unenforceable in accordance with Applicable Law or should otherwise be altered or amended in any way. The Parties acknowledge and agree that nothing in this Section 5.3(7)(b)

- 55 -

is intended to cap, waive, derogate from or otherwise limit the right of the Vendor to pursue any claims against the Purchaser it may have as a result of the failure of the Purchaser to satisfy its obligations under Section 5.3 or any other circumstances giving rise to the obligation of the Purchaser to pay to the Vendor the Reverse Termination Fee.

Section 5.4

Notwithstanding the foregoing, Purchaser shall not make any written communications to any of employees of the Corporations (including the Employees) without first providing Vendor with the form of such proposed communication and obtaining the prior written consent of Vendor, such consent not to be unreasonably withheld. Notwithstanding anything to the contrary in this Agreement, the Vendor shall not be required to disclose any information to the Purchaser if such disclosure would be reasonably likely to (a) jeopardize any solicitor-client or other legal privilege or (b) contravene any Applicable Law, fiduciary duty or binding agreement entered into prior to the date hereof. None of the Vendor or the Corporations makes any representation or warranty as to the accuracy of any information (if any) provided pursuant to this Section 5.4, and the Purchaser may not rely on the accuracy of any such information, in each case other than as expressly set forth in the representations and warranties contained in Article 3 of this Agreement. The information provided pursuant to this Section 5.4 will be held in strict confidence and will be used solely for the purpose of evaluating and effecting the transactions contemplated hereby.

Section 5.5

Purchaser Pre-Closing Transactions

(1) Subject to the Vendor’s approval, which approval shall not be unreasonably withheld, upon the written request of the Purchaser, and solely to the extent that Vendor, in its sole discretion, determines that the actions described herein would not be prejudicial to the Vendor, having regard, without limitation, to the taxation, financial and legal implications thereof, the Vendor shall cause the Corporations to use commercially reasonable efforts to: (i) perform such reorganizations of its corporate structure, capital structure, business, operations and assets or such other transactions as the Purchaser may reasonably request (each, a “Purchaser Pre-Closing Transactions”), and (ii) cooperate with the Purchaser and its advisors in order to facilitate the Purchaser’s determination of the Purchaser Pre-Closing Transactions and any transactions or other steps following the Closing to be undertaken and the manner in which they will be effected. For certainty, the Purchaser Pre-Closing Transactions will not include any transaction that is inconsistent with or adverse to the purpose or intent of a Vendor Pre-Closing Transaction, and neither Vendor’s action or inaction with respect to the Purchaser Pre-Closing Transactions will, regardless of whether it results in a failure by the Vendor to satisfy any of its obligations in this Section 5.5, result in a breach of any covenant, representation or warranty of Vendor, or result in any condition of Closing to not be satisfied.

- 56 -

(2) The Purchaser agrees that it will be responsible for all costs and expenses associated with the Purchaser Pre-Closing Transactions to be carried out at its request and shall indemnify and save harmless the Vendor and the Corporations from and against any and all Taxes, liabilities, losses, damages, claims, costs, expenses, interest awards, judgments and penalties suffered or incurred by any of them in connection with or as a result of any such Purchaser Pre-Closing Transaction, including any of the foregoing that arise in the event that Closing does not occur.

The Purchaser shall safeguard all Personal Information collected from the Vendor in accordance with applicable Privacy Laws and in a manner consistent with the degree of sensitivity of the Personal Information and, furthermore, maintain at all times the security and integrity of the Personal Information. The Purchaser shall not make any copies of the Personal Information or any excerpts thereof or in any way re-create the substance or contents of the Personal Information if Closing does not occur for any reason and shall return all Personal Information to the Vendor or destroy such Personal Information at the Vendor’s request.

The Party responsible for the preparation of an applicable Stub Period Return (the “Preparing Party”) shall prepare each Stub Period Return on a basis consistent with (i) Applicable Laws and (ii) to the extent consistent with Applicable Laws, the past practices and procedures of the Corporations.

The Receiving Party shall notify the Preparing Party in writing within thirty (30) days in the case of an income Tax Return, and ten (10) days in the case of any other Tax Return, after delivery to it of a Stub Period Return if it has any comments with respect to items set forth in such Stub Period Return, including the substance of its comments. To the extent the Preparing Party agrees with the Receiving Party’s comments, then the Tax Returns shall be filed on a basis that reflects such comments. To the extent the Preparing Party does not agree with such comments, the Preparing Party shall notify the Receiving Party in writing no later than two (2) Business Days after receipt of the Receiving Party’s comments specifying the reasons for such disagreement. The Parties shall then make reasonable efforts forthwith to resolve any such disagreements, failing which, the Parties agree to cause the Selected Accountant to resolve such disagreements at least five (5) Business Days prior to the due date therefor (taking into account any available extensions), and any such resolution shall be final and binding upon the Parties. The fees and expenses of the Selected Accountant shall be borne equally by the Parties. Notwithstanding the foregoing, for each Stub Period Return where the Purchaser is the Preparing Party, the Purchaser shall, at the request of the Vendor, cause such return to contain (i) a request to carry back losses, credits or other available tax attributes that are solely attributable to a Pre-Closing Tax Period to such earlier taxation years or periods as are specified by the Vendor in its sole discretion, and/or (ii) an election by the Corporation pursuant to subsection 256(9) of the ITA in respect of its taxation year ending immediately before the acquisition of control of it by the Purchaser. The Purchaser will cause the Corporations to timely remit any Taxes shown as owing on such Stub Period Returns.

fashion such data and other information as may reasonably be required for the preparation, review and filing of all Tax Returns and in order to contest any Tax matter, prepare for any audit by a governmental Authority or to pursue any refund, objection or appeal; and preserving such data and other information until the expiry of any applicable limitation period under Applicable Law with respect to such Tax Returns of the Corporations; provided that, for the avoidance of doubt, neither the Vendor nor any Affiliate of the Vendor shall have any obligation to provide or make available to any Person all or any portion of any Tax Return of the Vendor or of any Affiliate of the Vendor (other than the Corporations).

(3) Tax Notice. If any of the Purchaser Indemnified Parties receive any written proposal to assess or reassess, assessment, reassessment, appeal or notification of similar proceeding with respect to any Tax in respect of which a claim may be made for indemnification under this Agreement (each, a “Tax Notice”), such Purchaser Indemnified Party shall promptly (but in any event within ten (10) days of receipt) deliver a copy of the Tax Notice to the Vendor, together with all correspondence relating to, and any other documents received in respect of, such Tax Notice; provided, however, that failure to give such Tax Notice on a timely basis shall not affect the indemnification provided hereunder except to the extent the Indemnifier shall have been actually prejudiced as a result of such failure.

(4) Tax Contest Carriage. Where a Tax Notice relates to a Pre-Closing Tax Period, provided that the Vendor has, after receiving written notification of a Tax Notice, unconditionally acknowledged in writing its obligation to indemnify the Purchaser Indemnified Parties in respect of such Taxes, the Vendor shall have the exclusive authority to control, at its own expense, any submissions in respect of such Tax Notice and any objection or appeal in respect of such Tax Notice (each, a “Tax Contest”) and may make all decisions in connection with such Tax Contest. Without limiting the foregoing, the Vendor may, in its sole discretion, pursue or forego any and all administrative appeals, proceedings and conferences with any Taxing Authority with respect thereto, and may, in its sole discretion, contest the Tax Contest in any permissible manner, provided that neither the Vendor nor the Purchaser Indemnified Parties may settle any Tax Contest without the prior written consent of the other, which consent shall not be unreasonably withheld, conditioned or delayed; provided further that the Purchaser Indemnified Parties shall only require the Vendor’s consent to settle that portion of a Tax Contest that relates to Taxes for any Pre-Closing Tax Period or Taxes for any other Tax Period for which the Vendor must indemnify the Purchaser Indemnified Parties. If the Vendor fails within sixty (60) days of receipt of a Tax Notice to assume control of a Tax Contest in accordance with this Section 5.8(4), then the Vendor shall be deemed to have waived its right to control the Tax Contest and the Purchaser Indemnified Parties shall have the right to settle and/or dispute the matter as they deem reasonable.

(5) Joint Carriage. The Vendor and the Purchaser Indemnified Parties shall jointly control and participate in all proceedings taken in connection with (A) any Tax Contest relating to Taxes for any Straddle Period and (B) any Tax Contest relating partly to Pre-Closing Tax Periods and partly to other taxable periods. Neither the Vendor nor any of the Purchaser Indemnified Parties shall settle any such Tax Contest without the prior written consent of the other, which consent shall not be unreasonably withheld, conditioned or delayed.

(6) Tax Refunds. Except as provided below, any refunds or credits of Taxes (including any interest paid or credited with respect thereto net of any Taxes paid by any of the Corporations on such interest) of, or with respect to, any of the Corporations for any Pre-Closing Tax Period will be for the account of the Vendor (except to the extent such refunds or credits were reflected in the calculation of the Net Working Capital). The Purchaser shall promptly inform the Vendor of any such refunds or credits to which the Vendor may be entitled hereunder and shall pay to the Vendor an amount equal to the amount of such refunds or credits within 10 days following the date such refunds or credits were paid or credited by the relevant Governmental Authority to any of the Corporations, as applicable. Notwithstanding the foregoing, any Tax refund, credit or other Tax benefit in any Pre-Closing Tax Period attributable or due to the carryback of net operating loss, tax item, tax attribute or other Tax benefit from any Post-Closing Tax Period shall be solely for the account of Purchaser. Any payment made to Vendor pursuant to this Section 5.8 shall constitute an increase to the Purchase Price.

(7) Amendments to Tax Returns. Except as required by Applicable Law or in accordance with Section 5.8(4), none of the Purchaser or any of the Corporations shall, or cause or permit their Affiliates to, without the prior written consent of the Vendor, (a) refile, amend or otherwise modify any Tax Return of any of the Corporations filed for a Pre-Closing Tax Period or Straddle Period, or (b) make any Tax election that would have any retroactive effect to any Pre-Closing Tax Period. The Vendor shall have no liability whatsoever resulting from any action by the Purchaser or any of the Corporations contrary to this Section.

(8) Proration of Taxes. In the case of any Tax that is payable for a Straddle Period, the portion of such Tax relating to the Pre-Closing Tax Period shall equal the portion of such Tax that would have been payable if the relevant Tax period ended on and included the Closing Date. Any payments made prior to the Closing with respect to a Straddle Period shall be taken into account as though the relevant Taxable period ended on the Closing Date.

(9) Vendor Pre-Closing Transactions. Other than the Vendor Pre-Closing Transactions, which shall be implemented as described on Schedule 1.1(172), except in the Ordinary Course of Business, the Vendor shall not undertake any other similar actions relating to structure, corporate organization, reorganization, recapitalization, or intercompany account settlement without the Purchaser’s consent.

Section 5.9

Intercompany Arrangements

The Vendor shall take such action and execute such documents as may be necessary so that concurrently with the completion of the Transaction, all intercompany loans, notes and advances, tax sharing or similar agreements, and all intercompany receivables and payables, in each case among any of the Corporations on the one hand and any of the Suncor Group, on the other hand, shall be settled, discharged or otherwise cancelled, as applicable.

The Purchaser agrees not to amend, reduce or terminate any such insurance policies or the coverage thereunder or to agree to any of the foregoing.

Section 5.11

Access to Books and Records

The Purchaser has the right to have its representatives present during any such inspection.

Section 5.12

(1) For a period of seven years after the Closing Date, the Purchaser shall not permit the Corporations to amend, repeal or modify any provision in their respective constating documents or by-laws relating to exculpation or indemnification of former officers and directors in a manner that would adversely affect the rights of former officers and directors in respect of actions or omissions taken before the Effective Closing Time, it being the intent of the Parties that the officers and directors of the Corporations before the Closing shall continue to be entitled to exculpation and indemnification to the greatest extent permitted under the Applicable Law of the jurisdiction governing such entity.

(2) After the Effective Closing Time, the Purchaser shall cause each of the Corporations, as applicable, to exculpate (to the greatest extent permitted by Applicable Law) and indemnify, defend and hold harmless, each of their directors and officers in office immediately before the Effective Closing Time against all damages, costs, obligations, expenses and fees (including reasonable legal fees) to the fullest extent permitted under the constating documents and by-laws of each such entity in effect as of the date of this Agreement.

In furtherance of the foregoing, if any third party requires the consent of Vendor or any of its Affiliates to the disclosure of claims data, insurance coverage or information maintained by an insurance company or other third party in respect of any claim (including any claims under any Vendor insurance policies relating to periods prior to the Closing), such consent shall not be unreasonably withheld.

(2) Vendor shall use commercially reasonable efforts to purchase an OIL wrap Commercial Market Property/Business Interruption insurance policy in the amounts and coverages set forth on Schedule 5.17.

Section 5.18

Such notice shall specify whether the potential Damages arise as a result of a claim by a non-Affiliated Person against the Indemnified Party (a “Third Party Claim”) or whether the potential Damages do not so arise (a “Direct Claim”), and shall also specify with reasonable particularity (to the extent that the information is available):

(a)

the factual basis for the Direct Claim or Third Party Claim, as the case may be; and

(b)

the amount of the potential Damages arising therefrom, if known.

- 70 -

If, the Indemnifier does not receive notice of a particular claim in time effectively to contest the determination of any liability susceptible of being contested or to assert a right to recover an amount under applicable insurance coverage, then the liability of the Indemnifier to the Indemnified Party under this Article 7 shall be reduced to the extent that Damages are incurred by the Indemnifier resulting from the Indemnified Party’s failure to give such notice on a timely basis. Nothing in this Section 7.7 shall be construed to affect the time within which a Notice of Claim must be delivered pursuant to Section 7.8(1) in order to permit recovery pursuant to Section 7.4 or Section 7.5 as the case may be.

Section 7.8

Time Limits for Notice of Claim

(1) Notice by the Purchaser. No Damages may be recovered from the Vendor pursuant to Section 7.4(a) through Section 7.4(i) unless a Notice of Claim is delivered by the Purchaser on or before the following dates:

(a)

with respect to Vendor Fundamental Representations, there is no outside date for Delivery of a Notice of Claim;

(b)

with respect to the Vendor Environmental Representations, on or before the last day of the Vendor Environmental Representations Survival Period;

(c)

with respect to a breach of any other representation or warranty of the Vendor contained in this Agreement or in any certificate executed and delivered pursuant to this Agreement, on or before the last day of the Representations Survival Period;

(d)

with respect to the Excluded Pre-Closing Environmental Liabilities, on or before the third anniversary of the Closing Date;

(e)

with respect to any breach or any non-fulfilment of any covenant or agreement on the part of the Vendor contained in this Agreement or in any certificate executed and delivered pursuant to this Agreement or in respect of the Vendor Pre-Closing Transactions, on or before the sixth anniversary of the Closing Date; and

(f)

with respect to any Vendor Taxes, to the extent that such Tax was not specifically taken into account on the Closing Financial Statements, on or before the ninetieth (90th) day after the closing of the applicable statute of limitations (including any extension thereof); provided that for purposes of clarity the gross amount of an item shall be specifically taken into account if it is ultimately reflected as a net number due to financial consolidation.

Unless a Notice of Claim has been given on or before the dates set out above with respect to each particular representation, warranty, covenant and agreement, the Vendor shall be released on such date from all obligations in respect of that particular representation, warranty, covenant or agreement and from the obligation to indemnify the Purchaser Indemnified Parties in respect thereof pursuant to Section 7.4(a) through Section 7.4(i), as the case may be.

- 71 -

(2) Notice by the Vendor. No Damages may be recovered from the Purchaser pursuant to Section 7.5(a) through Section 7.5(d) unless a Notice of Claim is delivered by the Vendor on or before the following dates:

(a)

with respect to Purchaser Fundamental Representations, there is no outside date for Delivery of a Notice of Claim; and

(b)

with respect to a breach of any other representation or warranty of the Purchaser contained in this Agreement or in any other agreement, certificate or instrument executed and delivered pursuant to this Agreement, or in respect of the Purchaser Pre-Closing Transactions, on or before the last day of the Representations Survival Period;

(c)

with respect to any breach or any non-fulfilment of any covenant or agreement on the part of the Purchaser contained in this Agreement or in any other agreement, certificate or instrument executed and delivered pursuant to this Agreement, on or before the sixth anniversary of the Closing Date.

Unless a Notice of Claim has been given on or before the dates set out above with respect to each particular representation, warranty, covenant and agreement, the Purchaser shall be released on such date from all obligations in respect of that particular representation, warranty, covenant or agreement and from the obligation to indemnify the Vendor Indemnified Parties in respect thereof pursuant to Section 7.5(a) through Section 7.5(d) as the case may be.

(3) Waiver of Potential Defence. If the date by which a Notice of Claim must be given as set out in Section 7.8(1) or Section 7.8(2) in respect of a particular representation, warranty, covenant or agreement has passed, an Indemnified Party that might otherwise have been entitled to indemnification had such date not passed shall not be entitled to assert a right to give a Notice of Claim on the basis that it did not know and could not reasonably have known of the existence of the breach of that representation, warranty, covenant or agreement, or of any other element necessary to make a claim for Damages in respect thereof prior to such date. Each Party irrevocably agrees not to assert in any proceeding that it should be relieved from any of the provisions of this Article 7 by reason that it did not know and could not reasonably have known of the existence of any breach of representation, warranty, covenant or agreement or of any other element necessary to make a claim for Damages in respect thereof.

Section 7.9

Notice of and the Defence of Third Party Claims

With respect to a Third Party Claim, the Indemnifier shall have the right to participate in or, by giving notice to that effect to the Indemnified Party not later than 30 days after receipt of the Notice of Claim with respect to such Third Party Claim and subject to the rights of any insurer or other third party having potential liability therefor, to elect to assume the defence of such Third Party Claim at the Indemnifier’s own expense and by the Indemnifier’s own counsel, and the Indemnified Party shall have the right to participate in the defence of any Third Party Claim assisted by counsel of its own choosing. The Indemnified Party shall not settle or compromise any Third Party Claim without the prior written consent of the Indemnifier.

- 72 -

Section 7.10

Assistance for Third Party Claims

The Indemnifier and the Indemnified Party shall use all reasonable efforts to make available to the party which is undertaking and controlling the defence of any Third Party Claim:

(a)

those employees whose assistance, testimony or presence is necessary to assist such party in evaluating and in defending any Third Party Claim; and

(b)

all documents, records and other materials in the possession of such party reasonably required by such party for its use in defending any Third Party Claim,

and shall otherwise co-operate with the party defending such Third Party Claim.

Section 7.11

Settlement of Third Party Claims

Subject to the proviso in Section 7.7, if an Indemnifier elects to assume the defence of any Third Party Claim as provided in Section 7.9, the Indemnifier shall not be liable for any legal expenses subsequently incurred by the Indemnified Party in connection with the defence of such Third Party Claim. However, if the Indemnified Party bona fide believes on reasonable grounds that the Indemnifier has failed to take steps to defend diligently such Third Party Claim, the Indemnified Party may, at its option and on thirty (30) days written notice to the Indemnifier, elect to assume the defence of and to compromise or settle the Third Party Claim assisted by counsel of its own choosing and the Indemnifier shall, subject to Section 7.6, be liable for all reasonable costs and expenses paid or incurred in connection therewith. Without the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld, the Indemnifier shall not, while defending such Third Party Claim, thereafter enter into any compromise or settlement of any Third Party Claim; provided, however, that if the terms of the proposed settlement involved solely the payment of money by the Indemnifier and such consent is not obtained for any reason, the liability of the Indemnifier shall be limited to the proposed settlement amount.

Section 7.12

Direct Claims

With respect to a Direct Claim, the Indemnifier shall have a period of 30 days from receipt of a Notice of Claim in respect thereof within which to investigate and respond to the Indemnified Party in writing to such Direct Claim. If the Indemnifier shall object to the indemnification of the Indemnified Party in respect of such Direct Claim, the Indemnifier shall specify in reasonable particularity the basis for such objection, and the Indemnifier and the Indemnified Party shall, within 30 days of the Indemnified Party’s receipt of such objection, attempt to agree in good faith upon the rights of the respective parties with respect to such Direct Claim to which Indemnifier shall have objected. If the Indemnifier and the Indemnified Party are unable to agree as to indemnification, the Indemnified Party shall be permitted to submit such disputes to the courts as set forth in Section 11.12. The Indemnified Party shall make available to the Indemnifier the information relied upon by the Indemnified Party to substantiate its right to be indemnified, together with all other information as may be reasonably requested by the Indemnifier. If the Indemnifier does not so respond within such period, the Indemnifier shall be deemed to have rejected such Direct Claim, in which event the Indemnified Party shall be free to pursue such remedies as may be available to it.

- 73 -

Section 7.13

Reductions and Subrogation

If the amount of Damages incurred by an Indemnified Party at any time subsequent to the making of an Indemnity Payment is reduced by:

(a)

any net Tax benefit actually realized (whether by refund or by a reduction in Taxes otherwise payable) by the Indemnified Party in the taxable year in which such Damages were incurred, in any carryback Tax period prior to the taxable year in which such Damages were incurred, or the single Tax year immediately following the taxable year in which such Damages were incurred; provided that Damages shall be increased by any Tax costs, basis reduction, fees or expenses incurred as a result of the Damages or receipt of an Indemnity Payment. For purposes of this Section 7.13(a), the amount of any “Tax benefits actually realized” shall equal the excess, if any, of (i) the hypothetical Tax liability of the Indemnified Party calculated by excluding the relevant Tax deductions attributable to such Damages, over (ii) the actual Tax liability of the Indemnified Party calculated by taking into account the relevant Tax deductions attributable to such Damages and treating such deductions as the last items in such calculation; or

(b)

any recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by or against any other Person,

the amount of such reduction (less any costs, expenses (including Taxes) or premiums incurred in connection therewith) shall promptly be repaid by the Indemnified Party to the Indemnifier. Upon making a full Indemnity Payment, the Indemnifier shall, to the extent of such Indemnity Payment, be subrogated to all rights of the Indemnified Party against any third party in respect of the Damages to which the Indemnity Payment relates. Until the Indemnified Party recovers full payment of its Damages, any and all claims of the Indemnifier against any such third party on account of such Indemnity Payment shall be postponed and subrogated in right of payment to the Indemnified Party’s rights against such third party. The applicable Indemnified Parties shall use commercially reasonable efforts to recover from insurance policies or other applicable sources of recovery the maximum portion of any Damages of such Indemnified Parties.

Section 7.14

Exclusive Remedy

From and after the Closing, the equitable remedies and the rights of indemnity set forth in this Article 7 are the sole and exclusive remedy of each Party and its Indemnified Parties in respect of any misrepresentation, breach of warranty or breach or non-fulfillment of covenant by the other Party hereunder, whether occurring before or after Closing. Accordingly, each Party waives, from and after the Closing, any and all rights, remedies and claims that such Party and its Indemnified Parties may have against the other, whether at law, under any statute or in equity (including claims arising under any Environmental Laws, claims for breach of contract, breach of representation and warranty, negligent misrepresentation and all claims for breach of duty), or otherwise, directly or indirectly, relating to the provisions of this Agreement or the transactions contemplated by this Agreement other than the rights of indemnity and equitable remedies as expressly provided for in this Article 7 and other than those arising from fraud or wilful misconduct.

(c)

by the Vendor if the completion of the Transaction has not occurred on or before the date that is one hundred twenty (120) days following the date of this Agreement (as such date may be postponed as set forth below, the “Outside Date”) due to the failure of the condition set forth in Section 6.3(1), provided that if on such date the condition set forth in Section 6.3(1) (Required Regulatory Approvals) shall not have been satisfied and all other conditions set forth in Section 6.2 and Section 6.3 (other than those conditions that by their terms are to be satisfied at Closing) shall have been satisfied, the Purchaser shall have the right to postpone the Outside Date (i) by an initial period of up to forty five (45) days by Purchaser’s delivery of the applicable Extension Notice and, (ii) by a subsequent period of up to forty five (45) days by Purchaser’s delivery of the applicable Extension Notice; it being agreed that (A) five (5) Business Days prior to the expiry of the Outside Date or the expiry of any extension period referenced above, the Purchaser shall irrevocably advise the Vendor in writing whether it will elect to postpone the Outside Date (in each case an “Extension Notice”), and (B) the latest Outside Date resulting from all such extensions, if exercised, would occur two hundred and ten (210) days from the date of this Agreement, and further provided that the Vendor may not terminate this Agreement pursuant to

Section 11.10

Time

For every provision of this Agreement, time is of the essence.

Section 11.11

Governing Law

This Agreement is governed by, and is to be construed and interpreted in accordance with, the laws of the Province of Ontario and the laws of Canada applicable in the Province of Ontario.

Section 11.12

Submission to Jurisdiction

Each Party agrees: (i) that any action or proceeding relating to this Agreement may (but need not) be brought in any court of competent jurisdiction in the Province of Ontario, and for that purpose now irrevocably and unconditionally attorns and submits to the jurisdiction of such Ontario court; (ii) that it irrevocably waives any right to, and will not, oppose any such Ontario action or proceeding on any jurisdictional basis, including forum non conveniens; and (iii) not to oppose the enforcement against it in any other jurisdiction of any judgment or order duly obtained from an Ontario court as contemplated by this Section 11.12. Each of the Vendor and the Purchaser irrevocably appoints the respective Persons identified in Section 11.9 as its agent to receive on its behalf service of summons and any other legal process which may be served in any action, suit or proceeding. Such service may be made by mailing or delivering a copy of such process to the applicable party in care of its agent at the address given in Section 11.9 and each of the Parties hereby irrevocably authorizes and directs the respective agents to accept such service on their behalf. If and to the extent that such service and any summons or other legal process cannot for any reason be effected upon the applicable agent as in this Agreement provided, each of the Parties further irrevocably consents to the service of any and all legal process in any such action, suit or proceeding by the mailing of copies of such process in the manner specified in Section 11.9. Nothing in this Section 11.12 shall affect the rights of the Parties to serve legal process in any other manner permitted by Applicable Law.

Section 11.13

Entire Agreement

This Agreement together with the Ancillary Agreements and the Confidentiality Agreement constitute the entire agreement between the Parties with respect to the subject matter and supersede all prior agreements, negotiations, discussions, undertakings, representations, warranties and understandings, whether written or oral. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the Parties in connection with the subject matter of this Agreement, except as specifically set forth herein and in the Ancillary Agreements. The Parties are not relying on any other information, discussion or understanding in entering into this Agreement and the Ancillary Agreements and completing the Transaction.

Section 11.14

Amendment

No amendment, supplement, restatement or termination of any provision of this Agreement is binding unless it is in writing and signed by each Person that is a Party to this Agreement at the time of the amendment, supplement, restatement or termination.

Section 11.15

Waiver

No waiver of any provision of this Agreement is binding unless it is in writing and signed by all the Parties to this Agreement entitled to grant the waiver. No failure to exercise, and no delay in exercising, any right or remedy, under this Agreement will be deemed to be a waiver of that right or remedy. No waiver of any breach of any provision of this Agreement will be deemed to be a waiver of any subsequent breach of that provision.

Section 11.16

Severability

If any provision of this Agreement is or becomes illegal, invalid or unenforceable in any jurisdiction, the illegality, invalidity or unenforceability of that provision will not affect:

(a)

the legality, validity or enforceability of the remaining provisions of this Agreement; or

(b)

the legality, validity or enforceability of that provision in any other jurisdiction.

Section 11.17

Assignment and Enurement

Except as expressly set forth herein, no Party may assign its rights or obligations under this Agreement. Purchaser may assign its right or obligations under this Agreement to a wholly owned Subsidiary of Guarantor without the consent of Vendor; provided that such Subsidiary has agreed in writing to be bound by this Agreement and is capable of fulfilling Purchaser’s obligations hereunder; provided further that Guarantor’s obligations under the Guarantee shall continue in respect of this Agreement (and such assignment will not be effective until the Vendor has received a written agreement, in a form and substance satisfactory to the Vendor, which provides for the continuation of all of the Guarantor’s obligations under the Guarantee in respect of the Subsidiary and this Agreement). This Agreement enures to the benefit of and binds the Parties and their respective successors and permitted assigns. For greater certainty, permitted assigns shall include successors by amalgamation, and nothing in this Section 11.17 shall prohibit the Purchaser and/or any Affiliate of the Purchaser from amalgamating with PCLI at any time following the Closing.

Section 11.18

Counterparts and Electronic Transmission

This Agreement may be executed in any number of counterparts, each of which when executed and delivered is an original but all of which taken together constitute one and the same instrument. To evidence its execution of an original counterpart of this Agreement, a Party may send a copy of its original signature on the execution page hereof to the other Party by electronic transmission and such transmission shall constitute delivery of an executed copy of this Agreement to the receiving Party.
