(iii) Seller will have thirty (30) days (the “Seller’s Review Period”) from its receipt of the Buyer’s Objection to review and respond to it, and the Parties will thereafter attempt in good faith to reach an agreement with respect to any matters in dispute. If Seller and Buyer are unable to resolve their disagreement within sixty (60) days following the Seller’s Review Period, they will refer such disagreement to the Accounting Firm, who will, acting as experts and not as arbitrators, determine, only with respect to the remaining differences so submitted, whether and to what extent, if any, the Final Working Capital Statement requires adjustment.

Seller and Buyer will direct the Accounting Firm to use its best efforts to render its determination within twenty (20) Business Days. The Accounting Firm’s determination will be conclusive and binding upon Buyer and Seller.

Buyer and Seller will each pay one half (1/2) of the fees and disbursements incurred by the Accounting Firm. Buyer and Seller will make readily available to the Accounting Firm all relevant books and records and all other items and information reasonably requested by the Accounting Firm.

To the extent a dividend is paid by any of the Rangeland Companies to Seller after the Working Capital Date, the amount of the Closing Date payment in Section 2.2(c) will be adjusted downward by the amount of the dividend paid.

(i) Prior to the Closing Date, Seller shall notify Buyer of additions or changes to the Schedules to this Agreement required to reflect events since the date of this Agreement or facts discovered by Seller after the date hereof so as to cause Seller’s representations and warranties contained herein (other than any which speak as to a particular date) to be true and correct in all material respects as of the Closing Date. Notices given by Seller pursuant to this Section 5.1(c) will be deemed to have amended the Schedules to this Agreement, to have qualified the representations and warranties contained in Sections 4.1 and 4.2, and to have corrected any misrepresentation or breach of warranty that otherwise might have existed hereunder by reason of the fact, circumstance, event or development (with the result that no misrepresentation or breach shall be deemed to have occurred), in each case to the extent of the disclosure contained in such notice, including for purposes of Section 7.1(b).

Buyer and Seller shall use their respective reasonable best efforts to: (I) make such filings promptly (and in any event within fourteen (14) days) following the date of execution of this Agreement by Buyer; (II) respond promptly to any requests for additional information and documentary materials made by the Competition Bureau and/or the Investment Review Division of Industry Canada; (III) make any further filings that may be necessary, proper or advisable in connection therewith; (IV) cause the waiting periods under the Competition Act to expire or to obtain a no-action letter or advance ruling certificate under the Competition Act at the earliest possible date; (V) successfully complete the approval process under the Investment Canada Act at the earliest possible date; and (VI) resist in good faith, at each of their respective cost and expense (including the institution or defence of legal proceedings), any assertion that the transactions contemplated hereby should not proceed to completion; all to the end of expediting consummation of the transactions contemplated hereby. Each of Buyer and Seller shall consult with the other prior to any meetings, by telephone or in person, with the staff of the applicable Governmental Authorities and each of Buyer and Seller shall have the right to have a representative present at any such meeting (except that Buyer, with respect to Buyer’s application for

(ii) cooperate with each other and take all reasonable steps necessary to obtain authorizations and other consents, Permits and approvals for, or as a consequence of, the purchase and sale of the Shares from all other applicable Governmental Authorities.

(b) Specific Assignments.

(i) (A) With respect to any agreement, contract, licence, lease, easement, Right-of-Way or Permit (a “Subject Instrument”) which (1) is material to the operation of the Rangeland Business Unit as it is currently operated by the Seller Group, and either (2) required consent for the assignment thereof to RPC or RMC in connection with the conveyance of the RPC Assets and the Rangeland Marketing Business Assets by members of the BP Group to RPC and RMC, respectively, or (3) now requires consent for the assignment thereof to RPC or RMC by reason of the change of control respecting RPC and RMC that will occur upon consummation of the transactions contemplated hereby, Seller shall take such actions as are commercially reasonable and necessary, and Buyer shall cooperate fully with Seller in all commercially reasonable respects, to effect assignment thereof as of the Closing Date. It is understood that such actions by Seller shall not include any requirement of Seller to expend money, commence any litigation or offer or grant any accommodation (financial or otherwise) to any third party. In the event that Seller is unable to obtain the requisite approval for assignment of any such Subject Instrument, or in the event such Subject Instrument is required to be amended or supplemented and is not so amended or supplemented as of the Closing Date, and such assignment is reasonably necessary to conduct the operation of the Rangeland Business Unit in the ordinary course of business without giving rise to a material adverse effect on the Rangeland Business Unit, at the written request of Buyer on or before the Closing Date (except where such action would be unlawful or prohibited by such Subject Instrument), Seller shall (x) retain any such Subject Instrument and shall enter into an arrangement with Buyer to provide the applicable Rangeland Company with the benefits of such Subject

Instrument, provided that the applicable Rangeland Company shall perform Seller’s obligations thereunder arising on or after the Closing Date (and indemnify Seller against Losses suffered in connection therewith) until such Subject Instrument is assigned to the applicable Rangeland Company or expires at the earliest opportunity in accordance with its terms, or is properly amended or supplemented, and (y) take all commercially reasonable and necessary actions required to assign to the applicable Rangeland Company, or amend or supplement, any such Subject Instrument as soon as practicable after the Closing Date.

(B) In addition to the obligations of Seller under Section 5.3(b)(i)(A), from the Closing Date until the first anniversary of the Closing Date, Seller shall take such actions as are commercially reasonable and necessary, including expending money in an aggregate amount not to exceed three million dollars ($3,000,000), and Seller shall cooperate fully with Buyer in all commercially reasonable respects, to remedy or cure the absence or invalidity of or defect in any easement, right-of-way, permit, licence or other right of access forming part of the Rangeland Pipeline Business Assets. Expenditures by Seller under this Section 5.3(b)(i)(B) shall not be included for purposes of satisfying any of the limits under Section 8.11 but shall be included for purposes of determining the limit under Section 8.13(c).

(ii) Notwithstanding Seller’s obligations pursuant to Section 5.3(b)(i), the assignment of any Subject Instrument which requires consent for assignment, or amendment or supplement, may be effected after the Closing Date. The Purchase Price shall not be subject to adjustment, and the Closing of the transactions contemplated by this Agreement shall not be delayed, by reason of any inability to obtain consent for assignment of any such Subject Instrument or any such amendment or supplement. Buyer acknowledges that certain consents to the transactions contemplated by this Agreement may be required from parties to Subject Instruments (written or otherwise) to which any of Seller or other member of the Seller Group is a party, and such consents may not be obtained (provided that Seller has complied with its obligations under this Section 5.3(b)). Buyer agrees that Seller shall not have any liability

whatsoever to Buyer arising out of or relating to the failure to obtain any consents that may have been or may be required in connection with the transactions contemplated by this Agreement or because of the default, acceleration or termination of any such Subject Instrument as a result thereof (provided that Seller has complied with its obligations under this Section 5.3(b)). Buyer further agrees that no representation, warranty or covenant of Seller contained herein shall be breached or deemed breached and no condition of Buyer shall be deemed not to be satisfied as a result of the failure to obtain any consent or as a result of any such default, acceleration or termination or any lawsuit, action, claim, proceeding or investigation commenced or threatened by or on behalf of any Persons arising out of or relating to the failure to obtain any consent or any such default, acceleration or termination (provided that Seller has complied with its obligations under this Section 5.3(b)).

(iii) With respect to any Subject Instrument that may not be properly assigned to a Rangeland Company because of the failure to obtain the required consent as described in Section 5.3(b)(i)(A)(2) or (3) or that may not be operated or used by Seller for the applicable Rangeland Company’s benefit, Buyer shall indemnify, defend and hold harmless Seller and the other members of the BP Group from and against any liability that Seller or any other members of the BP Group may have in connection with such non-transferred Subject Instruments as a result of the transactions contemplated by this Agreement; provided that, for the avoidance of doubt, it is expressly understood and agreed that, in the event Seller is unable to provide the Rangeland Companies the benefits of any such Subject Instrument, Buyer shall not be required to indemnify Seller against Losses suffered in connection therewith until and to the extent Seller, with full cooperation from Buyer and the Rangeland Companies in all respects, is able to provide the Rangeland Companies the benefit of any such Subject Instrument.

(c) Notification. From the date hereof to and including the Closing Date, each Party shall promptly notify the other Party if it obtains knowledge that any representation or warranty of Seller in this Agreement or any agreement contemplated hereby or information set forth in the Schedules hereto is not true and correct in all material respects, or if such Party obtains knowledge of any material errors in, or omissions from, the Schedules to this Agreement.

(d) Transition Services Agreement. Buyer and Seller shall execute and deliver at Closing the Transition Services Agreement.

(e) Working Capital Amount. The Parties agree to use commercially reasonable efforts to minimize the Working Capital Amount and the aggregate Working Capital of the Rangeland Companies at Closing.

(f) Other Actions. Buyer and Seller shall otherwise use their respective commercially reasonable efforts to cause the satisfaction of all covenants in this Article 5 and the conditions precedent in Sections 7.1 and 7.2 and the Closing to occur as soon as reasonably practicable after the date of this Agreement.

All offers of employment by Buyer and terminations of employment by Seller pursuant to this Article 6 and the Parties’ respective obligations in this Article 6 shall be conditional upon the Closing pursuant to this Agreement and the execution and delivery by each Transferred Employee of a release of Seller in form and substance satisfactory to Seller, acting reasonably.

6.6 Transfer Time

All Transferred Employees shall become employees of the Employer as of 12:01 a.m. on the Closing Date and, except as otherwise provided herein, at such time Employer shall assume and be responsible for payment of all salaries and benefits and all other costs and liabilities relating to services by the Transferred Employees after the Closing Date except that, with regard to an Employee on Leave, such obligations shall not attach until such Employee commences employment with the Employer.

The Employer shall provide to all Transferred Employees employee benefits in accordance with employee benefit plans (such as non-registered employee savings plans, registered retirement savings plans and welfare benefit plans), programs, policies and pay practices (such as vacations, bonuses and sick and disability leaves) provided to employees of the Employer in substantially similar employment circumstances, which shall, in aggregate, be the same as or better than the benefits specified in Part 4 of Schedule ”L”, with coverage effective as of the Closing Date, and the Employer shall

The Employer shall not reduce any Transferred Employee’s initial salary or wages as an employee of the Employer during the eighteen (18) month period after the Closing Date.

6.9 Vacation

Seller shall be responsible for paying the Transferred Employees for any vacation due as of the Closing Date under the applicable vacation policy of Seller or other members of the BP Group (“Seller Vacation Policy”). The Employer will provide Transferred Employees who, based upon the recognized credited service amounts of such Transferred Employees with Seller or other members of the BP Group, were eligible for a greater amount of annual vacation under Seller Vacation Policy than they are under the Employer’s vacation policy even after the Employer recognizes such Transferred Employees’ credited service amounts, with their Seller annual vacation amount; provided that the annual vacation amount for any Transferred Employee shall not in any event exceed five (5) weeks. Between the Closing Date and the end of the year in which the Closing occurs, the Employer shall permit all Transferred Employees to take the same number of hours of vacation on an unpaid basis as those Transferred Employees would have been eligible to take immediately prior to the Closing Date under the Seller Vacation Policy based upon the recognized credited service amounts of such Transferred Employees with Seller or other members of the BP Group.

The Employer’s severance policy established under this Section 6.10 shall recognize the Transferred Employees’ recognized credited service amounts with Seller or other members of the BP Group.

6.11 Service Credit

From and after the Closing Date, the Transferred Employees shall be given credit for their service recognized by Seller or other members of the BP Group prior to the Closing Date for all purposes, including eligibility, vesting and benefit determination and accrual under all applicable plans and programs of the Employer, as well as for purposes of determining any vacation, severance or other related benefits to be provided in the manner described above.

6.12 Employee Records

Buyer agrees that all information with respect to Employees provided to it or its Affiliates by Seller shall be kept and maintained by Buyer and its Affiliates as confidential information and shall not be divulged to any third party unless the Employer has the consent of the Employee or, alternatively, is under legal compulsion pursuant to Applicable Laws to disclose such confidential information.

8.6 Procedures Relating to Indemnification Between Buyer and Seller

Following the discovery of any facts or conditions which could reasonably be expected to give rise to a Loss or Losses for which indemnification is provided under this Agreement, the Party seeking indemnification (the “Indemnified Party”) shall, as promptly as reasonably possible thereafter, provide written notice to the Party from

whom indemnification is sought (the “Indemnifying Party”), setting forth the specific facts and circumstances, in reasonable detail, relating to such Loss or Losses and the amount of Loss or Losses (or a reasonable, good-faith estimate thereof if the actual amount is not known or not capable of reasonable calculation) (“Indemnification Notice”); provided, however, that failure to give such Indemnification Notice on a timely basis shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually and materially prejudiced as a result of such failure. Notwithstanding the foregoing:

(a) a Buyer Indemnified Party shall not be entitled to make a claim against Seller under Section 8.2(b) unless and until (i) Buyer shall have provided Seller written notice of default; and (ii) Seller shall have failed to cure such default within sixty (60) days after Seller’s receipt of Buyer’s notice; and

(b) a Seller Indemnified Party shall not be entitled to make a claim against Buyer under Section 8.1(c) unless and until (i) Seller shall have provided Buyer written notice of default; and (ii) Buyer shall have failed to cure such default within sixty (60) days after Buyer’s receipt of Seller’s notice.

8.7 Procedures Relating to Indemnification for Third Party Claims

(a) In order for an Indemnified Party to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any Person against the Indemnified Party (a “Third Party Claim”), such Indemnified Party must provide an Indemnification Notice to the Indemnifying Party of the Third Party Claim as promptly as reasonably possible after receipt by such Indemnified Party of notice of the Third Party Claim. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five (5) Business Days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim; provided, however, that failure to provide an Indemnification Notice, or deliver copies of all notices and documents, in a timely manner shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually and materially prejudiced as a result of such failure.

(b) If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defence thereof and, if it so chooses and acknowledges its obligation to indemnify the Indemnified Party therefor, to assume the defence thereof with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party. Notwithstanding any acknowledgment made

pursuant to the immediately preceding sentence, the Indemnifying Party shall continue to be entitled to assert any limitation on its indemnification responsibility contained in Sections 8.11 and 8.12. Should the Indemnifying Party so elect to assume the defence of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defence thereof. If the Indemnifying Party assumes such defence, the Indemnified Party shall have the right to participate in the defence thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood, however, that the Indemnifying Party shall control such defence. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defence thereof. If the Indemnifying Party chooses to defend any Third Party Claim, the Parties shall cooperate in the defence or prosecution of such Third Party Claim. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information which are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Whether or not the Indemnifying Party shall have assumed the defence of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, or consent to the entry of any judgment with respect to, such Third Party Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld).

8.8 Losses Net of Insurance and Taxes

(a) Insurance. The amount of any and all Losses under this Article 8 and elsewhere under this Agreement shall be determined net of any amounts recovered or recoverable by the Indemnified Party under insurance policies, indemnities or other reimbursement arrangements with respect to such Losses. Each Party hereby waives, or will procure the waiver of, any subrogation rights that its insurer may have with respect to any indemnifiable Losses.

(b) Taxes. In determining the amount of any Loss for which any Party is entitled to indemnification under this Article 8, the gross amount thereof shall be reduced by any net Tax Benefit realized by such Party in connection with such Loss to the extent such Tax Benefit results directly from the incurrence of such Loss. If an indemnification payment

hereunder results in incremental Tax being payable by the Indemnified Party, the amount shall be equal to:

(i) the gross amount of such Loss minus the Tax Benefit realized by such Party as determined above, divided by

(ii) one (1) minus the Tax Rate;

provided, however, that no indemnification payment shall be payable until final settlement of such Tax liability with the relevant Tax authority, and only upon receipt by the Indemnifying Party of a copy of an official communication issued by the relevant Tax authority which evidences such final settlement of the Tax liability and, in such circumstances, the Indemnifying Party will also pay to the Indemnified Party interest, at the Seller’s Interest Rate if the Indemnifying Party is Seller or at the Buyer’s Interest Rate if the Indemnifying Party is Buyer, on the indemnification amount payable from the date the obligation to make such indemnification payment arose until the date on which such indemnification payment is made. For purposes of this Section 8.8:

“Tax Benefit” means, as to a Party which is indemnified against Losses hereunder, the Tax Rate multiplied by the amount of any income tax deduction or allowance in any year arising from any Loss that entitles the Indemnified Party to indemnity under this Agreement. If a change in law replaces or otherwise supplements the federal or provincial income tax on corporations with another method of taxation, the Parties hereto agree to negotiate in good faith a new definition of Tax Benefit; and

“Tax Rate” means the rate of Tax exigible under the laws applicable to a relevant Person for any relevant period of time.

8.9 Attorneys’ Fees

In connection with any litigation arising out of this Agreement or to enforce any indemnification claim pursuant to this Agreement, the prevailing Party shall be entitled to recover from the non-prevailing Party the prevailing Party’s reasonable attorneys’ fees and costs, on appeal or otherwise.

8.10 Time Limitation

Except as otherwise provided herein, any claim by any Buyer Indemnified Party for indemnity arising under this Agreement, including pursuant to Section 8.2, shall be brought within one (1) year after the Closing Date; provided that any claim arising under Section 8.2(a) for Excluded Liabilities, Section 5.1(f) or under Sections 9.3(c) and 9.3(f) may be brought within ten (10) years of the Closing Date, any claim arising under

Section 5.1(g) may be brought within two (2) years of the Closing Date and any claim arising under Section 5.1(e) may be brought within the Applicable Period. A claim shall be deemed to have been brought only upon delivery of a proper Indemnification Notice to the other Party at the notice address set forth in Section 12.2. Any claim required to be made within such one (1) year period, ten (10) year period or other period referred to in this Section 8.10, as the case may be, not so timely made shall be forever barred.

8.11 Monetary Limitation

Except as otherwise provided in this Agreement, Buyer shall have no claim under this Agreement against Seller or any other member of the BP Group for any Losses unless and until the aggregate of all such Losses incurred or sustained by Buyer Indemnified Parties (excluding any expenditures pursuant to Section 5.3(b)(i)(B)) exceeds five million dollars ($5,000,000) and then only for the excess over five million dollars ($5,000,000) (the “Threshold”); provided that Losses amounting to less than four hundred thousand dollars ($400,000) in the aggregate arising out of the same occurrence or matter shall not be aggregated with other Losses for purposes of determining whether and when the Threshold has been reached. After the Threshold has been reached, Seller shall have no obligation to indemnify Buyer Indemnified Parties under this Agreement with respect to such matters for any Losses amounting to less than four hundred thousand dollars ($400,000) in the aggregate arising out of the same occurrence or matter. For purposes of this Section 8.11, Losses shall exclude Rights-of-Way Losses, which are addressed in Section 8.13 below.

8.12 Limitation of Liability

Seller’s aggregate liability for indemnification pursuant to this Agreement, including Section 8.2, but subject to Sections 8.2(a) and 9.3(f), shall in no event exceed an amount equal to fifty million dollars ($50,000,000).

8.13 Rights-of-Way Monetary Limitation

(a) Buyer shall have no claim under this Agreement against Seller or any other member of the BP Group for any Rights-of-Way Losses unless and until the aggregate of all such Rights-of-Way Losses incurred or sustained by the Buyer Indemnified Parties exceeds four million dollars ($4,000,000) and then only for the excess over four million dollars ($4,000,000) (the “Level 1 Threshold”), subject to Sections 8.13(b), (c) and (d).

(b) For any Rights-of-Way Losses incurred or sustained by the Buyer Indemnified Parties in an aggregate amount in excess of the Level 1 Threshold but less than or equal to eight million dollars ($8,000,000) (the “Level 2 Threshold”), Buyer shall only have a claim under this Agreement against Seller for fifty percent (50%) of such excess over the Level 1 Threshold.

(c) Subject to Section 8.12, Buyer shall have a claim under this Agreement against Seller for one hundred percent (100%) of the excess of the aggregate amount of Rights-of-Way Losses incurred or sustained by Buyer Indemnified Parties over the Level 2 Threshold, provided that the sum of Seller’s aggregate liability for indemnification for Rights-of-Way Losses pursuant to this Agreement, including Section 8.2 and this Section 8.13, plus any payment made by Seller to Buyer pursuant to Section 5.3(b)(i)(B), shall in no event exceed five million dollars ($5,000,000).

(d) Notwithstanding the foregoing, Seller shall have no obligation to indemnify the Buyer Indemnified Parties under this Agreement with respect to such matters for any Rights-of-Way Losses amounting to less than four hundred thousand dollars ($400,000) in the aggregate arising out of the same occurrence or matter.

8.14 Mitigation

Each Party hereto shall take all reasonable steps and use all commercially reasonable efforts to mitigate any and all Losses.

8.15 Adjustment to Purchase Price

Any indemnity payment under this Agreement shall be treated as an adjustment to the Purchase Price.

8.16 Subrogation

Each Party shall assign to the other Party and subrogate the other Party to all its rights and remedies against any Person (other than, with respect to rights and remedies of Seller, those against the BP Group and its insurers) in respect of any payment made by the other Party in respect of any indemnification or liability assumed by the other Party pursuant to this Agreement or as a result of this Agreement (including legal fees and other costs of litigation). Each Party shall provide all reasonable cooperation of assistance required by the other Party in making and prosecuting any claim for recovery against any such Person to the extent that payment is made by the other Party. Neither Party shall knowingly take any action to impair any such right or remedy of the other Party to recover any such payment.

Should Seller or BP Resources, acting on their own behalf and that of RMC and RPC, disagree with the competent taxing authority’s proposed revisions to the agreed amounts, Seller or BP Resources, acting in their sole discretion, shall decide whether to file notices of objection with the competent taxing authority or notices of appeal to a court of competent jurisdiction (both in accordance with the Tax Act and the Alberta Tax Act) with respect to any such assessment or reassessment.

Buyer and its Affiliates (including the Rangeland Companies) shall co-operate fully with Seller and its counsel in the conduct, defence or compromise of any such Seller’s Tax Matter, including by executing and delivering waivers of relevant statutes of limitations and powers of attorney; provided, however, that if the matters in issue have the potential to prospectively affect the Tax liability of Buyer or any of its Affiliates (including the Rangeland Companies), Buyer shall have the right to participate in such proceeding to the extent reasonable in the circumstances.

(b) Buyer and its Affiliates (including the Rangeland Companies) shall have the sole right to control and direct the conduct, defence or compromise of any matter, including any audit, proposed adjustment, claim, assessment, reassessment, administrative or judicial proceeding or the filing of any

amended return or claim for refund, involving any Tax liability for which Buyer or its Affiliates (including the Rangeland Companies) may be responsible (excluding, for greater certainty, any Seller’s Tax Matters) (a “Buyer’s Tax Matter”) and to employ counsel of its own choice at its own expense. Seller shall co-operate fully, and shall cause the other members of the BP Group to co-operate fully, with Buyer and its counsel in the conduct, defence or compromise of any such Buyer’s Tax Matter, including by executing and delivering waivers of relevant statutes of limitations and powers of attorney; provided, however, that if the matters in issue have the potential to retroactively affect the Tax liability of Seller or the other members of the BP Group, Seller shall have the right to participate in such proceeding to the extent reasonable in the circumstances.

9.8 Transaction a Share Sale

(a) Seller and Buyer (on its own behalf and that of its Affiliates, including the Rangeland Companies) hereby acknowledge and agree that the purchase and sale of the Shares, as described in Section 2.1 of this Agreement (the “Subject Transaction”), shall be, for purposes of the Tax Act and the Alberta Tax Act, treated at all material times as the purchase and sale of shares which are non-depreciable “capital property” as that term is defined in Section 54 of the Tax Act. For greater certainty, Seller and Buyer (on its own behalf and that of its Affiliates, including the Rangeland Companies) acknowledge and agree that they will not advocate in any way or at any time that the Subject Transaction should be treated for purposes of the Tax Act and the Alberta Tax Act as the sale and purchase of depreciable assets or any type of transaction other than as specified above.

(b) Should any relevant taxing authority take the view that the Subject Transaction is in law anything other than the purchase and sale of shares which are non-depreciable “capital property” as that term is defined in Section 54 of the Tax Act, Buyer (and its Affiliates, including the Rangeland Companies) shall co-operate (in accordance with Section 9.5(a) of this Agreement) with Seller in advocating by whatever means necessary that the Subject Transaction is to be treated for Tax purposes as the purchase and sale of shares which are non-depreciable “capital property” as that term is defined in Section 54 of the Tax Act .

(c) Should it ultimately be determined by a court of competent jurisdiction or otherwise that the Subject Transaction is not in law a purchase and sale of shares which are non-depreciable “capital property” as that term is defined in Section 54 of the Tax Act, but is instead the sale and purchase of depreciable assets or any other type of transaction that results in a tax benefit to Buyer (or its Affiliates, including the Rangeland Companies), Buyer shall make a payment to Seller equal in amount to the value of the tax benefit realized by Buyer (or its Affiliates, including the Rangeland Companies) as a result of the recharacterization of the Subject Transaction, such value to be determined by Seller in a reasonable manner.

ARTICLE 10

Seller agrees that it will consult with Buyer in advance of taking any such actions following the Closing Date with a view towards establishing a mutually agreeable plan for such visits so that these actions will not unreasonably interfere with the normal operation of the Rangeland Business Unit.

(b) To the extent the Partnership is unable to obtain the written confirmation contemplated in Section 10.2(a) within thirty (30) days from the date this Agreement is signed, then upon the written request of Buyer, at Buyer’s sole cost and expense and only to the extent necessary to comply with the Partnership’s disclosure obligations under Rule 3-05 of Regulation S-X, Seller shall use reasonable commercial efforts to provide the Partnership and its representatives (including its legal counsel and independent auditors) reasonable access during normal business hours to such historical financial information as may then be in Seller’s possession or control (and to those persons who are responsible for such information) that is necessary to allow the Partnership to prepare the historical financial statements required by Rule 3-05 of Regulation S-X, and to enable the audit thereof.

(c) The obligations of Seller to disclose or provide reasonable access to any such historical financial information shall terminate three (3) years after the date of this Agreement. Seller shall have no liability whatsoever to Buyer or any other Person for information provided or disclosed hereunder, or the accuracy or sufficiency thereof or in connection with any claim arising out of such information. Buyer acknowledges that Seller makes no representation or warranty with respect to any such information and expressly disclaims any implied or constructive representation or warranty. Buyer shall reimburse Seller for all actual costs incurred by

Seller in performing its obligations under this Section 10.2 and shall indemnify Seller for any and all Losses suffered, sustained, paid or incurred by Seller directly or indirectly with respect to such matter.

Buyer and Seller agree that, from the date hereof to and including the Closing Date, no public release or announcement concerning the transactions contemplated hereby shall be issued or made by either Party (including any member of the BP Group) without the prior consent of the other Party (which consent shall not be unreasonably withheld), except (a) as such release or announcement may be required by Applicable Laws or the rules or regulations of any securities exchange, whether in Canada or elsewhere (or in the opinion of counsel such release or announcement is appropriate or desirable under or in light of such laws and regulations), in which case the Party making the release or announcement shall allow the other Party reasonable time to comment on such release or announcement in advance of such issuance, and (b) that any member of the BP Group, including Seller, may make such an announcement to its employees. Notwithstanding the foregoing, Buyer and Seller shall cooperate to prepare a joint press release to be issued on the Closing Date and, upon the request of either Buyer or Seller, at the time of the signing of this Agreement. Buyer and Seller agree to keep the terms of this Agreement confidential, except to the extent required by Applicable Laws or for financial reporting purposes or as otherwise provided herein and except that the Parties may disclose such terms to their respective (and in the case of Seller, the BP Group’s) counsel, auditors, accountants, agents, advisors and other representatives as necessary in connection with the ordinary conduct of their respective businesses (so long as such Persons agree to keep the terms of this Agreement confidential).

13.6 Survival Of Covenants, Representations and Warranties

The covenants, representations and warranties in this Agreement and in any other document delivered in connection herewith shall survive the Closing solely for purposes of Sections 8.1, 8.2 and 8.3. The representations and warranties in Section 4.1(i) with respect to the Rangeland Pipeline System Real Property set forth in Part 1 of Schedule ”D” shall not survive and shall terminate at Closing.

13.7 Entire Agreement

This Agreement, the attached Schedules and the agreements referred to herein or executed simultaneously herewith, set forth the entire agreement and understanding of the Parties in respect to the transactions contemplated hereby and thereby and supersede all prior agreements, arrangements and undertakings, whether written or oral, relating to the subject matter hereof (other than the Confidentiality Agreement, which shall continue in effect). No representation, promise, inducement or statement of intention, whether written or oral, has been made by either Party which is not embodied in or superseded by this Agreement or the Confidentiality Agreement or in the documents referred to herein, and no Party shall be bound by or liable for any alleged representation, promise, inducement or statement of intention not so set forth whether in the Information Memorandum, in certain “data rooms”, management presentations or any other form in expectation of the transactions contemplated by this Agreement. Except as otherwise specifically provided in this Agreement, no conditions, usage of trade, course of dealing or performance, understanding or agreement purporting to modify, vary, explain or supplement the terms or conditions of this Agreement will be binding unless hereafter made in writing and signed by the Party to be bound, and no modification will be effected by the acknowledgment or acceptance of documents containing terms or conditions at variance with or in addition to those set forth in this Agreement, except as otherwise specifically agreed to by the Parties in writing.

13.8 Assignment

This Agreement and any rights and obligations hereunder shall not be assignable or transferable by Buyer or Seller (including by operation of law in connection with a merger or sale of stock, or sale of substantially all the assets, of Buyer or Seller) without the prior written consent of the other Party and any purported assignment without such consent shall be void and without effect; provided, however, that each of Buyer and Seller may (a) assign any and all of its rights and interests hereunder to one or more of its Affiliates and (b) designate one or more of its Affiliates to perform its obligations hereunder; provided further that each of Buyer and Seller shall remain responsible for the performance of all of its respective obligations hereunder.

13.9 Waiver

Any of the terms, covenants, representations, warranties or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party

waiving compliance. The failure of either Party at any time or times to require performance of any provision hereof shall in no manner affect the right at a later time to enforce the same. No waiver by either Party of any condition, or of any breach of any term, covenant, representation or warranty contained in this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation or warranty.

13.10 Expenses

Whether or not the transactions contemplated hereby are consummated, and except as otherwise specifically provided in this Agreement, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby, including legal, due diligence, accounting and investment banking fees and expenses, shall be paid by the Party incurring such costs or expenses.

13.11 Counterparts

This Agreement may be executed simultaneously in one or more counterparts (including by means of facsimile signature pages), all of which shall be considered one and the same agreement, and shall become effective when one or more such counterparts have been signed by each of the Parties and delivered to the other Party.

13.12 No Strict Construction

Notwithstanding the fact that this Agreement has been drafted or prepared by one of the Parties, Buyer and Seller confirm that both they and their respective counsel have reviewed, negotiated and adopted this Agreement as the joint agreement and understanding of the Parties, and the language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no doctrine of strict construction shall be applied against any Person.

13.13 Schedules

The disclosures in the Schedules hereto (including any disclosures made in amendments made pursuant to Section 5.1(c)) are to be taken as relating to the representations and warranties of Seller as a whole. Matters listed once on the Schedules shall be deemed disclosed with reference to all sections of the Schedules and all of Sections 4.1 and 4.2 of this Agreement. The inclusion of information in the Schedules hereto shall not be construed as an admission that such information is material to the Rangeland Business Unit, the Rangeland Business Unit Assets or the Seller Group. In addition, matters reflected in the Schedules are not necessarily limited to matters required by this Agreement to be reflected in such Schedules. Such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature. Prior to the Closing, Seller shall have the right at all times to supplement, modify or update the Schedules hereto; provided, however, that any such supplements, modifications or updates shall be subject to the provisions

of Section 5.1(c). The Schedules are incorporated herein by reference and made a part hereof.

13.14 Severability

Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be valid and effective under Applicable Laws, but if any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, (a) such provision shall be deemed to be automatically amended to the extent necessary to comply with Applicable Laws and permit enforcement and (b) such finding shall not affect the binding effect of the other provisions of this Agreement, unless, in either case, such amendment or finding (after giving effect to any permitted amendment) materially impairs the economic benefit or protections to be derived by a Party from the transactions contemplated hereby, taken as a whole.

13.15 No Third Party Beneficiaries

Except as provided with respect to indemnification as set forth in Article 8 and elsewhere in this Agreement, nothing in this Agreement shall confer any rights upon any Person other than the Parties and their respective successors and permitted assigns.

13.16 Time of Essence

With regard to all rights and obligations of the Parties and all dates and time periods set forth or referred to in this Agreement, time is of the essence.

13.17 No Conditions

For the avoidance of doubt, the only conditions to Closing are those set forth in Sections 7.1 and 7.2 herein, and no other covenants or conditions set forth in this Agreement are intended to have any effect on the Closing or the payment of the Purchase Price.

13.18 Joint Liability

The liabilities of PipelineCo and MarketingCo in respect of any covenants or any other obligations stated under this Agreement to be covenants or obligations of Buyer shall be joint.

13.19 Enurement

This Agreement shall be binding upon and enure to the benefit of the Parties and their respective successors and permitted assigns.

IN WITNESS WHEREOF, the Parties have duly executed this Agreement as of the day and year first above written.
