If SEP does not deliver the Initial Statement to Contributor within 75 days following the Closing Date, then, at the election of Contributor, either (A) Contributor may prepare and present the Initial Statement within an additional 75 days thereafter or (B) the Estimated Working Capital shall be deemed to be the Final Working Capital, the Estimated Notes Balance shall be deemed to be the Final Notes Balance and the Estimated Cenex Adjustment shall be deemed to be the Final Cenex Adjustment, in each case, in accordance with the last sentence of Section 2.4(f). If Contributor prepares the Initial Statement in accordance with the immediately preceding sentence, all references to “Contributor” in Sections 2.4(b) and 2.4(d) shall be deemed to be references to “SEP” and all references to “SEP” shall be deemed, in Sections 2.4(b) and 2.4(d), to be references to “Contributor”.

independent accountants, in each case, relating to the preparation of the Initial Statement and the calculations related thereto, as well as all of the financial books, ledgers and records related thereto (the “Financial Records”), and SEP shall make reasonably available to Contributor the individuals responsible for and knowledgeable about the information used in, and the preparation or calculation of, the Initial Statement. Contributor acknowledges and agrees that access to the working papers of SEP’s independent accountants may be conditioned upon Contributor’s execution of a customary confidentiality and hold harmless agreement relating to such access to working papers in form and substance reasonably acceptable to SEP’s independent accountants.

(c) SEP shall, following the Closing through the date that the Final Statement becomes such in accordance with the last sentence of Section 2.4(f), take all actions necessary or desirable to maintain and preserve all Financial Records, policies and procedures on which the Initial Statement is based or on which the Final Statement is to be based so as not to impede or delay the determination of the amounts set forth in the Initial Statement or the preparation of the Notice of Distribution Adjustment Disagreement or the Final Statement in the manner and utilizing the methods permitted by this Agreement.

(d) In the event that Contributor concludes that the Initial Statement or any amount set forth therein has not been prepared on the basis required by this Agreement, Contributor shall submit a written notice to SEP on or prior to the expiration of the Distribution Adjustment Review Period (the “Notice of Distribution Adjustment Disagreement”), which notice shall set forth in reasonable detail the basis of Contributor’s disagreement, the amounts involved and the proposed determination of the dispute amount. If no Notice of Distribution Adjustment Disagreement is received by SEP on or prior to the expiration date of the Distribution Adjustment Review Period, then the Initial Statement shall be deemed to have been accepted by Contributor and shall become final and binding upon the Parties in accordance with the last sentence of Section 2.4(f).

(e) During the 30 days immediately following the expiration of the Distribution Adjustment Review Period (the “Distribution Adjustment Consultation Period”), the Parties shall seek in good faith to resolve any disagreement that they may have with respect to the matters specified in the Notice of Distribution Adjustment Disagreement.

(f) If, at the end of the Distribution Adjustment Consultation Period, the Parties have been unable to resolve all disagreements that they may have with respect to the matters specified in the Notice of Distribution Adjustment Disagreement, then the Parties shall submit separate written statements setting forth in detail their respective positions with respect to all matters that remain in dispute with respect to the Notice of Distribution Adjustment Disagreement (along with a copy of the Initial Statement marked to indicate those line items that are in dispute) to Ernst & Young LLP (the “Independent Accountant”) promptly thereafter. In the event that Ernst & Young LLP refuses or is otherwise unable to act as the Independent Accountant, the Parties shall cooperate in good faith to appoint an independent certified public accounting firm qualified and of national recognition in the United States and Canada that is mutually agreeable to the Parties, in which event “Independent Accountant” shall mean such firm. Within 30 days after the submission of such matters to the Independent Accountant, or as soon as practicable thereafter, the Independent Accountant, acting as an

expert and not as an arbitrator, will make a final determination, binding on the Parties, on the basis of the Agreed Valuation Principles and in accordance with this Section 2.4(f), of the appropriate amount of each of the matters that remain in dispute with respect to the Notice of Distribution Adjustment Disagreement. To the extent any amount determined by the Independent Accountant pursuant to the preceding sentence is calculated in Canadian Dollars, it shall be converted into its USD Currency Equivalent as of the Closing Date. There shall be no ex parte communications between either Party, on the one hand, and the Independent Accountant, on the other hand, relating to those matters in dispute, other than the initial written submission by the Parties of their respective positions on the matters in dispute and written answers by the Parties to written questions from the Independent Accountant. With respect to each disputed line item, the Independent Accountant’s determination, if not in accordance with the position of either Party, shall not be in excess of the highest, nor less than the lowest, of the amounts advocated in any Notice of Distribution Adjustment Disagreement or in the Initial Statement with respect to such disputed line item. For the avoidance of doubt, the Independent Accountant shall not review any line items or make any determination with respect to any matter other than those matters in the Notice of Distribution Adjustment Disagreement that remain in dispute. The statement setting forth the Working Capital on the Closing Date and the Notes Balance and Cenex Adjustment, in each case, as of the Closing Date that is final and binding on the Parties, as determined either through agreement of the Parties (deemed or otherwise) pursuant to Section 2.4(b), Section 2.4(d) and this Section 2.4(f) or through the determination of the Independent Accountant pursuant to this Section 2.4(f), is referred to herein as the “Final Statement”, and the determinations of the Working Capital, Notes Balance and Cenex Adjustment set forth in the Final Statement are respectively referred to as the “Final Working Capital”, the “Final Notes Balance” and the “Final Cenex Adjustment”.

(g) The cost of the Independent Accountant’s review and determination shall be shared equally by the Parties. During the review by the Independent Accountant, the Parties shall each make available to the Independent Accountant such individuals and such information, books, records and work papers, as may be reasonably required by the Independent Accountant to fulfill its obligations under Section 2.4(f); provided, however, that the independent accountants of the Parties shall not be obligated to make any working papers available to the Independent Accountant unless and until the Independent Accountant has signed a customary confidentiality and hold harmless agreement relating to such access to working papers in form and substance reasonably acceptable to such independent accountants.

(h) The “Post-Closing Adjustment” shall be an amount equal to the sum of (i) the Final Working Capital minus the Estimated Working Capital, (ii) the Estimated Notes Balance minus the Final Notes Balance and (iii) the Final Cenex Adjustment minus the Estimated Cenex Adjustment. If the Post-Closing Adjustment is a positive amount, then SEP shall distribute cash to Contributor in the amount of the Post-Closing Adjustment, which distribution shall be sourced by SEP solely from debt proceeds under indebtedness that meets all the requirements of Section 7.22(c). If the Post-Closing Adjustment is a negative amount, then Contributor shall contribute cash to SEP in an amount equal to the absolute value of the Post-Closing Adjustment. Any such payment shall be made within three Business Days after the Final Statement becomes such, together with interest thereon, from the Closing Date through the date on which the applicable Post-Closing Adjustment is paid, at the Interest Rate calculated and payable in accordance with Section 2.11.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES OF SEP

Except as set forth in the SEP Disclosure Schedule (which disclosure schedule sets forth items of disclosure with specific reference to the particular Section or subsection of this Agreement to which the information in such disclosure schedule relates; provided, however, that any information set forth in one Section or subsection of such disclosure schedule shall be deemed to apply to each other Section or subsection thereof or hereof to which its relevance could reasonably be expected to be pertinent), SEP represents and warrants to Contributor as follows:

Section 6.1 Organization and Qualification. SEP has been duly organized, is validly existing and is in good standing under the Laws of the State of Delaware.

Section 6.2 Corporate Authorization. SEP has all requisite limited partnership power and authority to execute and deliver this Agreement and the other Transaction Documents to which it is or will be a party, to perform its obligations hereunder and thereunder and to

consummate the Transactions. The execution and delivery of this Agreement and the other Transaction Documents, the performance of SEP’s obligations hereunder and the consummation of the Transactions have been duly authorized by all necessary action of SEP. This Agreement and the other Transaction Documents to which SEP is or will be a party have been or will be duly executed and delivered by SEP and, assuming the due authorization, execution and delivery of the Transaction Documents by each Person that is or will be a party thereto, constitute the legal, valid and binding obligations of SEP, enforceable against SEP in accordance with their terms, subject to the Bankruptcy and Equity Exception.

Section 6.3 Consents and Approvals. Except in connection, or in compliance, with the approvals, filings and notifications required by applicable Laws that are set forth on Section 6.3 of the SEP Disclosure Schedule (the “SEP Approvals”), no consent, approval, waiver, authorization, notice or filing is required to be obtained by SEP or any of its Affiliates from, or to be given by SEP or any of its Affiliates to, or be made by SEP or any of its Affiliates with, any Person (including any Government Entity) in connection with the execution, delivery and performance by SEP of this Agreement or the other Transaction Documents to which it is or will be a party or the consummation of the Transactions, except as would not, individually or in the aggregate, prevent or materially delay or impair the ability of SEP to consummate the Transactions.

Section 6.4 Non-Contravention. Assuming the receipt of all SEP Approvals, the execution and delivery by SEP of this Agreement and the other Transaction Documents to which it is or will be a party, the performance of its obligations pursuant to the Transaction Documents and the consummation of the Transactions will not constitute or result in (a) a violation of the Organizational Documents of SEP, (b) a breach or violation of, a termination of, a right of termination or default under, the creation or acceleration of any obligations under, or the creation of an Encumbrance on any of the assets of SEP pursuant to, any Contract to which SEP is a party (with or without notice or lapse of time or both) or (c) assuming the receipt of all Contributor Approvals, a breach or violation of, or a default under, any Law to which SEP or its Affiliates are subject, except, in the case of clause (b) or (c), as would not, individually or in the aggregate, prevent or materially delay or impair the ability of SEP to consummate the Transactions.

Section 6.5 Litigation and Claims. As of the date hereof, there is no civil, criminal or administrative action, suit, demand, claim, hearing, proceeding or investigation pending or, to the Knowledge of SEP, threatened, against SEP or any of its properties or assets before any Government Entity except as would not, individually or in the aggregate, prevent or materially impair or delay the ability of SEP to consummate the Transactions.

Section 6.6 Financing. SEP will have sufficient funds to pay the Cash Distribution to Contributor at the Closing, which distribution shall be sourced by SEP solely from debt proceeds under indebtedness that meets all the requirements of Section 7.22(c).

Section 6.7 Investment Intent. SEP is receiving the Contributed Interests for investment only and not with a view toward, or for sale in connection with, any distribution thereof, nor with any intention of distributing or selling the Contributed Interests (a) in violation of the Securities Act or any other applicable Law or (b) in a manner that would result in the recognition of gain or loss by Contributor for U.S. federal income tax purposes. SEP

acknowledges and agrees that the Contributed Interests may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of (i) without registration under the Securities Act, except pursuant to an exemption from such registration available under the Securities Act, and without compliance with any other applicable Law and (ii) without complying with the terms of the Organizational Documents of U.S. Holdco.

Section 6.8 No Brokers or Finders. There is no investment banker, broker, finder or other intermediary that has been retained by or is authorized to act on behalf of SEP or any of its Affiliates who is entitled to any fee or commission from SEP or any of its Affiliates in connection with the Transactions for which Contributor or any of its Affiliates would be liable.

Section 6.9 Issuance of Total Unit Consideration. Upon issuance, all of the Total Unit Consideration will be duly authorized, validly issued and outstanding, and will have been issued free of preemptive rights in compliance with Laws. Upon issuance, the Total Unit Consideration will be fully paid (to the extent required by the SEP Partnership Agreement) and nonassessable (subject to Del. Code ▇▇▇. Tit. 6, §§ 17-303, 17-607 and 17-804 (2007)). Upon consummation of the transactions contemplated by this Agreement, Contributor will acquire good and valid title to all of the Total Unit Consideration, free and clear of any Encumbrances other than transfer restrictions imposed thereon by securities Laws or arising under the SEP Partnership Agreement.

Section 6.10 SEP SEC Documents. SEP has timely filed with the Commission all forms, registration statements, reports, schedules and statements required to be filed by it under the Exchange Act or the Securities Act (all such documents filed on or prior to the date of this Agreement, collectively, the “SEP SEC Documents”). The SEP SEC Documents, including any audited or unaudited financial statements and any notes thereto or schedules included therein (the “SEP Financial Statements”), at the time filed (in the case of registration statements, solely on the dates of effectiveness) (except to the extent corrected by a subsequently filed SEP SEC Document filed prior to the date of this Agreement) (a) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading and (b) complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. The SEP Financial Statements were prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission) and fairly present (subject in the case of unaudited statements to normal, recurring and year-end audit adjustments) in all material respects the consolidated financial position and status of the business of SEP as of the dates thereof and the consolidated results of its operations and cash flows for the periods then ended. Deloitte & Touche LLP is an independent registered public accounting firm with respect to SEP and has not resigned or been dismissed as independent registered public accountants of SEP as a result of or in connection with any disagreement with SEP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures.

Section 6.11 Independent Investigation; No Other Representations or Warranties. SEP acknowledges that in making the decision to enter into this Agreement and to consummate the Transactions, SEP has relied solely on (a) the basis of its own independent investigation of the

Express U.S. Pipeline System, its components and the risks related thereto and (b) upon the express written representations, warranties and covenants in this Agreement. Without limiting the foregoing, SEP expressly acknowledges the provisions set forth in Section 5.26. Except for the representations and warranties contained in this Article VI, none of SEP, any of its Affiliates, any of its or their respective stockholders, trustees or Representatives, and any other Person has made or is making any other representation or warranty of any kind or nature whatsoever, oral or written, express or implied, with respect to SEP or its Affiliates, or its or their respective businesses, the Total Unit Consideration, this Agreement, the other Transaction Documents to which SEP is or will be a party or the Transactions. Except for the representations and warranties contained in this Article VI, (i) SEP disclaims, on behalf of itself and its Affiliates, any other representations or warranties, whether made by SEP, any of its Affiliates, any of their respective stockholders, trustees or Representatives or any other Person and (ii) SEP disclaims, on behalf of itself and its Affiliates, all Liabilities and responsibility for any other representation, warranty, opinion, projection, forecast, advice, statement or information made, communicated or furnished (orally or in writing) to Contributor or its Affiliates.

(b) Manuals. Following the Closing, Contributor shall, and shall cause its Affiliates to, provide SEP with full access to all operating procedures, manuals, guidelines and other procedures used in connection with the Express U.S. Pipeline System, including the general operating procedure control room manuals, the operating procedure control room manuals applicable to the Express U.S. Pipeline System, the portions of the emergency response plans applicable to the Express U.S. Pipeline System, the facility operating procedures for each pump station and terminal on the Express U.S. Pipeline System and the portions of welding manuals and integrity management plans, including facilities, natural hazards and tank integrity plans, and training program materials, modules, tests, evaluation

SEP shall pay all filing fees in connection with SEP Approvals. Contributor shall pay all filing fees for all Contributor Approvals.

(b) As promptly as practicable, and in no event later than fifteen Business Days after the date hereof, Contributor and SEP shall (i) promptly make any filings with, or notices to, the Wyoming Public Service Commission and promptly file any supplemental information required or requested in connection therewith and (ii) make all filings and notifications with all Government Entities that may be or may become reasonably necessary, proper or advisable under this Agreement and applicable Laws to consummate and make effective the Transactions.

(c) Contributor and SEP may not, without the consent of the other (which consent shall not be unreasonably withheld, delayed or conditioned), (i) cause any such filing or submission applicable to it to be withdrawn or refiled for any reason, including to provide the applicable Government Entity with additional time to review any or all of the Transactions or (ii) consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the Transactions at the behest of any Government Entity. Each of Contributor and SEP shall use commercially reasonable efforts to supply promptly any information and documentary material that may be requested pursuant to any applicable Laws in connection with such filings or submissions.

(d) Subject to applicable Laws relating to the sharing of information, Contributor and SEP shall promptly notify each other of any communication such other Party receives from any Government Entity (other than communications for purely logistical purposes) and permit such other Party to review in advance any proposed applications, notices, filings, submissions, undertakings, correspondence and communications of any nature (including responses to requests for information and inquiries from any Government Entity) by such Party, as applicable, to any Government Entity and shall provide such other Party with copies of all applications, notices, filings, submissions, undertakings, correspondence and communications of any nature (including responses to requests for information and inquiries from any Government Entity) between such Party, as applicable, or any of its Representatives, on the one hand, and any Government Entity or members of the staff of any Government Entity, on the other hand, in each case to the extent relating to the matters that are the subject of this Agreement and the other Transaction Documents, except with respect to Taxes (which are covered by Section 7.8). Except with respect to Taxes (which are covered by Section 7.8), neither Party shall agree to participate in any meeting or discussion with any Government Entity relating to the matters that are the subject of this Agreement (including in respect of satisfying or obtaining the SEP Approvals and the Contributor Approvals) or any of the other Transaction Documents unless such Party consults with such other Party in advance and, to the extent permitted by such Government Entity, gives such other Party the opportunity to attend and participate at such meeting or discussion. Contributor and SEP shall coordinate and cooperate fully with each other in exchanging such information and providing such assistance as each may reasonably request in connection with the foregoing and shall keep each other informed of the status of discussions relating to obtaining or concluding the SEP Approvals and the Contributor Approvals; provided, however, that the foregoing shall not require Contributor and SEP or any of their respective Affiliates (i) to disclose any information that in the reasonable judgment of such Party or any of its respective Affiliates (as the case may be) would result in the disclosure of any trade secrets of third parties or violate any of its obligations with respect to confidentiality, (ii) to disclose any privileged information or confidential competitive information of such Party or any of its respective Affiliates or (iii) to disclose the valuation of, or any communications analyses or other work product regarding the valuation of, the Contributed Interests, the Total Unit Consideration, the Companies or the Companies’ assets. If either Party seeks to withhold information from any of the other Party for any reason permitted by this Section 7.4(d), such Party, as applicable, shall nonetheless provide a redacted version of the information so withheld to the others and, subject to the requirement that such outside counsel not disclose the unredacted version to any other Person, a complete, unredacted version of the same to the outside legal counsel of the others. Neither Party shall be required to comply with any provision of this Section 7.4(d) to the extent that such compliance would be prohibited by applicable Law.

Section 7.5 Supplemental Disclosure. Any Disclosure Schedule may, from time to time, prior to the tenth day prior to the Closing Date, be supplemented or amended with respect to any event, condition, fact or circumstance that arises or with respect to which Knowledge is first obtained after the date of this Agreement, that would cause or constitute an inaccuracy in, or breach of, any representation or warranty in this Agreement to which such Disclosure Schedule relates. The Person supplementing or amending its Disclosure Schedules (the “Disclosing Party”) shall deliver a copy of the amendment or supplement, which shall clearly identify and highlight the relevant changes to such Disclosure Schedules (the “Supplemental Disclosure”) to

Contributor, if SEP is the Disclosing Party, or to SEP, if Contributor is the Disclosing Party (in each case, the “Receiving Party”). The Receiving Party shall have ten days after receipt of such Supplemental Disclosure (the “Termination Period”) in which to review the Supplemental Disclosure. If a Supplemental Disclosure discloses facts that would constitute a breach of the Disclosing Party’s representations and warranties hereunder and such breach would reasonably be expected to result in the failure of the condition to Closing specified in Section 8.2(a), if Contributor is the Disclosing Party, or Section 8.3(a), if SEP is the Disclosing Party, to be satisfied at the Closing, then SEP, if Contributor is the Disclosing Party, or Contributor, if SEP is the Disclosing Party, may terminate this Agreement by delivering a written notice of termination to the others prior to the expiration of the Termination Period (which termination notice shall specify the representation or warranty breached, identify the specific facts in the Supplemental Disclosure that constitute the breach and describe why the failure of the condition to Closing would reasonably be expected to occur). If a notice of termination is not received with respect to any Supplemental Disclosure within the Termination Period, the Receiving Party will be deemed to have waived its right to terminate with respect to such Supplemental Disclosure and the relevant Disclosure Schedule will be deemed, solely for the purpose of the Receiving Party’s condition to Closing as set forth in Section 8.2(a) or Section 8.3(a), as applicable, and not for any other purpose under this Agreement (including the indemnification provisions in Article X), to be amended and supplemented as described in the Supplemental Disclosure as of the date hereof. For the avoidance of doubt, no Supplemental Disclosure (whether or not a notice of termination is received with respect thereto during the Termination Period) shall be deemed to have amended or supplemented the relevant Disclosure Schedule for purposes of the condition to Closing set forth in Section 8.2(d).

Section 7.6 Insurance; Damage or Casualty Loss.

(a) If between the date hereof and the Closing Date, Contributor and its Affiliates become aware of a loss that has occurred to all or any portion of any Company’s properties prior to the Closing, which such loss is potentially covered by any of the Policies and such loss exceeds the applicable deductible under such Policy, then Contributor and its Affiliates shall cause the applicable Company to file a claim with the applicable insurance carriers and shall pay or cause to be paid to the applicable Company any insurance proceeds received for such loss.

(b) If between the date hereof and the Closing Date, Contributor and its Affiliates become aware of any claim of liability made against any of the Companies or a circumstance arises that may give rise to a liability claim against any Company prior to Closing, such claim or circumstance is potentially covered by any of the Policies and such claim or circumstance exceeds the applicable deductible under such Policy, then Contributor and its Affiliates shall cause the applicable Company to file a claim with the applicable insurance carriers and shall pay or cause to be paid to the applicable Company any insurance proceeds received for such loss.

(c) Between the date hereof and the Closing, Contributor shall not, and shall cause the Companies not to, voluntarily compromise, settle or adjust any amounts payable by reason of any losses or claims referenced in Section 7.6(a) or Section 7.6(b) in excess of $500,000 without first obtaining the written consent of SEP, such consent not to be unreasonably withheld, conditioned or delayed.

Section 7.7 Indebtedness.

Following the Closing, SEP shall, and shall cause each of the Companies to, jointly and severally, indemnify and hold harmless Contributor and its Affiliates from and against the Equity Percentage of any and all Losses arising from or relating to any Pre-Closing Letter of Credit with respect to which SEP has not obtained a Replacement Letter of Credit.

Subject to Section 10.4(i), Contributor shall be liable for and indemnify the SEP Indemnified Parties for (i) Taxes imposed on or with respect to any of the Companies or for which any of the Companies may otherwise be liable for any taxable year or period that begins before the Closing and ends on or before the Closing Date (a “Pre-Closing Period”) and, with respect to any taxable year or period beginning on or before and ending after the Closing Date (a “Straddle Period”), the portion of such taxable year or period ending at the end of the Closing Date, including any such Taxes for which any Company may be liable as a transferee or successor, (ii) the portion of the Transfer Taxes for which Contributor is liable under Section 7.8(d) or (iii) Taxes attributable to any taxable year or period beginning on or before the Closing Date imposed on any Company under Treasury Regulation Section 1.1502-6 or any similar provision of state, local or non-U.S. Law, other than, in the case of this clause (iii), any such Taxes attributable to any affiliated group of which SEP or any of its Affiliates (other than the Companies) is the common parent; provided, however, the Contributor’s liability for Taxes hereunder shall be reduced to take into account the amount of any such Taxes taken into account in determining the Financial Statements Current Liabilities. To the extent any of the Taxes described in the previous sentence gives rise to any Tax deduction or Tax credit for any SEP Indemnified Party, the amount which shall be payable pursuant to this Section 7.8(a) shall be determined in accordance with the principles set forth in Section 10.8(c). Contributor shall be entitled to any refund of Taxes of the Companies received for any Pre-Closing Period and, with respect to any Straddle Period, for the portion of such taxable year or period ending at the end of the Closing Date; provided, however, the Contributor’s entitlement to a refund of Taxes hereunder shall be reduced to take into account the amount of any such refund of Taxes taken into account in determining the Financial Statements Current Assets.

(g) Cancellation of Certain Tax Sharing Agreements. Prior to the Closing, all Tax allocation, Tax sharing, Tax indemnity and similar agreements, arrangements and understandings between any Company, on the one hand, and Contributor or any of its Affiliates (other than the Companies), on the other hand, shall be terminated with respect to each Company, and no Company will have any Liability under any such agreement, arrangement or understanding after the Closing.

Section 7.12 [Intentionally Omitted]

Section 7.13 Transitional Arrangements.

(a) Intercompany Agreements. Prior to or concurrently with the Closing, Contributor shall, and shall cause its respective Affiliates to, terminate all Intercompany Agreements existing prior to the Closing, except for Continuing Intercompany Agreements and Intercompany Agreements that by their terms will cease to include Contributor or its Affiliates (other than the Companies) as parties upon consummation of the Transactions, which shall remain in effect after the Closing Date.

(b) Non-Solicit. SEP and Contributor acknowledge that Section 7.13(e)(i) of the Original Purchase Agreement included certain non-solicitation covenants. In the event of a breach of such provision by the Contributors or their respective Affiliates (as such terms are defined in the Original Purchase Agreement) and upon SEP’s request, Contributor will use commercially reasonable efforts to exercise any rights Contributor may have under the Original Purchase Agreement with respect to such breach.

Section 7.14 Directors and Officers.

In addition to and in connection with the foregoing, SEP agrees that, for a period of 10 years following the Closing, it will indemnify and hold harmless each present and former partner, director and officer of any Company (in each case, when acting in such capacity), against the Equity Percentage of any costs or expenses (including reasonable attorneys’ fees), judgments, fines, Losses, claims, damages or Liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Closing, whether asserted or claimed prior to, at or within 10 years following the Closing, to the fullest extent that the Companies would have been permitted under applicable Law or their respective Organizational Documents in effect on the date hereof to indemnify such director or officer.

(b) SEP shall not, and shall cause its Affiliates not to, without consent of Contributor (which consent shall not be unreasonably withheld, delayed or conditioned), amend, restate or repeal any Organizational Documents of any Company within six years after the Closing unless such Organizational Document (after giving effect to such amendment, restatement or repeal and applicable Law) would provide for such Company to indemnify and hold harmless each present and former partner, director and officer of such Company (in each case, when acting in such capacity), against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, Losses, claims, damages or Liabilities incurred in

connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters in connection with acting in such capacity, to at least the same extent that such indemnification would be provided for under applicable Law or its Organizational Documents in effect on the Closing Date.

(c) If SEP or any Company (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of SEP or such Company, as the case may be, shall assume all of the obligations set forth in this Section 7.14.

(d) Contributor and SEP hereby acknowledge and agree that from and after the Closing each of the present and former partners, directors and officers of any Company shall be an express third-party beneficiary of this Section 7.14. The rights of such partners, directors and officers under this Section 7.14 shall be in addition to any rights such partners, directors and officers may have under the Organizational Documents of the Companies or under any applicable Contracts or Laws.

Section 7.15 [Intentionally Omitted]

Section 7.16 Financial Statements.

(a) After the date of this Agreement and prior to the Closing, Contributor shall deliver to SEP, as soon as reasonably feasible, the 2013 Unaudited Financials and copies of any monthly reports and quarterly or annual financial statements of the Companies, in each case, prepared in the ordinary course after the date of this Agreement and prior to the Closing, in a format historically utilized by the Companies.

(b) No later than 70 days after the Closing Date, Contributor shall deliver the following financial statements to SEP, each on a GAAP basis (including respective balance sheets, statements of income and cash flows and applicable footnotes), in such form as may be required by Rule 3-05(a) of Regulation S-X promulgated under the Securities Act to be filed with the Commission by SEP as a result of the Transactions, together with the unqualified audit opinion of the independent public accountants of the Companies for the financial statements in clause (i) below (collectively, the “Required Financials”): (i) audited consolidated financial statements of the U.S. Holdco (or other consolidation level acceptable to the Securities and Exchange Commission) at and for the years ended December 31, 2010, December 31, 2011 and December 31, 2012 and (ii) unaudited consolidated financial statements on a GAAP basis of U.S. Holdco (or other consolidation level acceptable to the Securities and Exchange Commission) at and for any period(s) for 2013 as may be required by Rule 3-05(a) of Regulation S-X.

(c) From the date hereof until delivery of the Required Financials to SEP in accordance with Section 7.16(b), Contributor shall keep SEP informed, and consult with SEP on a regular basis, with respect to the preparation of the Required Financials, including by promptly providing SEP with copies of any drafts of the Required Financials and promptly informing SEP of any correspondence and communications with the independent public accountants of the Companies relating to the Required Financials.

(d) Contributor shall use its commercially reasonable efforts to cause the independent public accountants of the Companies to provide to SEP no later than the date on which the Required Financials must be filed with the Commission any consent necessary to the filing of the Required Financials with the Commission and any such customary representation letters as are necessary in connection therewith, provided, however, that SEP shall cooperate with and assist Contributor and its Affiliates and the auditors engaged by the Companies, including promptly providing any information reasonably requested by any of them.

(e) SEP and Contributor agree that the liquidated damages owing from Contributor for Contributor’s breach of Section 7.16(b) shall be an amount equal to $1,720,000 (the “Liquidated Damages Payment”). Determination of Contributor’s breach shall not be affected by whether such breach resulted from reasons partially or totally outside of Contributor’s control, except to the extent such breach was caused primarily by SEP. Payment to SEP of the liquidated damages contemplated by this Section 7.16(e) shall be SEP’s sole and exclusive remedy for Contributor’s breach of Section 7.16(b). The liquidated damages so paid will be treated as a reduction in the Cash Distribution for all purposes (including for Tax purposes, to the maximum extent permitted by Law) and Contributor will irrevocably forfeit the right to any such amount payable.

(f) Contributor and SEP acknowledge and agree that (i) the Liquidated Damages Payment constitutes liquidated damages because the potential injury to SEP resulting from Contributor’s breach of Section 7.16(b) is uncertain and difficult to quantify, (ii) the amount of the Liquidated Damages Payment is reasonable and considers (A) the actual or anticipated harm that could be caused by Contributor’s breach of Section 7.16(b), (B) the difficulty of proving the loss arising from any such potential breach and (C) the difficulty of finding another, adequate remedy at law and (iii) the Liquidated Damages Payment is structured to function as damages resulting from Contributor’s breach and not as a penalty.

Section 7.17 [Intentionally Omitted]

Section 7.19 Third-Party Consents; Assignments. From the date of this Agreement and for up to one year after the Closing Date, Contributor shall use commercially reasonable efforts to obtain (and SEP shall cooperate with Contributor’s efforts to obtain) all consents, approvals, waivers, authorizations, notices or filings required to be obtained by any Company from, or to be given by any Company to, or made by any Company with, any Person that is not a Government Entity pursuant to the Contracts set forth on Section 7.19 of the Contributor Disclosure Schedule and any other Contracts, if any, to which a Company is a party and as to which a consent, approval, waiver, authorization, notice or filing is required in connection with the execution, delivery and performance of this Agreement and the other Transaction Documents and the consummation of the Transactions.

Section 7.20 Third-Party Indemnification. If at any time after the Closing, SEP or the Companies is subject to a claim that is reasonably expected to give rise to Losses for SEP or the Companies in excess of $2,500,000 that SEP reasonably believes would be covered under Section 7.20 of the Original Purchase Agreement, then upon SEP’s request, Contributor will use commercially reasonable efforts to exercise its rights under Section 7.20 of the Original Purchase Agreement to the extent applicable. If such exercise results in a recovery in favor of Contributor, then Contributor shall, following receipt of payment in respect of such recovery, transfer to SEP and the Companies the amount, if any, by which such recovery exceeds all Losses incurred or to be incurred by Contributor in respect of or related to Contributor’s pursuit of such claim and/or pursuit of indemnification in respect thereof on an after-Tax basis, except to the extent the indemnification rights of Contributor or any of its Affiliates pursuant to the Original Purchase Agreement and the exercise thereof in respect of any claim or claims would be limited or reduced by the satisfaction of SEP’s request and, provided that, SEP and its Affiliates (including the Companies) agree to indemnify, hold harmless and defend, Contributor and its Affiliates from and against any and all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities arising in connection with pursuing or satisfying SEP’s request, including in connection with any demand, claim, counterclaim, cross claim or other action, suit, proceeding or investigation, without defense, offset or counterclaim of any kind.

Section 7.21 [Intentionally Omitted]

Section 7.22 Tax Treatment; Section 704(c); Transaction Recourse Debt.

(a) The Parties intend that the contribution of the Contributed Interests to SEP and the Cash Distribution by SEP (each as described in Article II) are properly characterized as transactions, respectively, described in Section 721(a) and 731 of the Code. The Parties acknowledge and agree that, because the U.S. Holdco, Express Pipeline LLC and Platte Pipe Line Company are all disregarded entities prior to the Closing, the contribution of the Contributed Interests to SEP shall be treated as a contribution of the Equity Percentage of each underlying asset of such entities to SEP, followed by a contribution of such proportionate part of these assets by SEP, and the remaining part of these assets by Contributor, to a new partnership constituted by the U.S. Holdco for U.S. federal and any applicable state and local tax purposes.

(b) The Parties hereby agree that, for purposes of applying Section 704(c) of the Code to the transactions contemplated by this Agreement, each of SEP and the U.S. Holdco shall adopt the remedial method under Treasury Regulation Section 1.704-3(d) with respect to the difference between fair market value and adjusted tax basis, as of the Closing Date, of the assets treated as having been contributed to it for U.S. federal income tax purposes (“Built-in Gain”). For purposes of determining Built-in-Gain pursuant to this Section 7.22(b), the Parties shall agree to cooperate in good faith in the preparation of a schedule reflecting the relative fair market value of the assets deemed contributed to SEP pursuant to Section 7.22(a) (“Allocation Schedule”). Within 90 days following the Closing,

Contributor shall submit a draft Allocation Schedule to SEP for its review and reasonable comment. Within 15 days after the receipt of such draft Allocation Schedule, SEP shall submit any comments it may have to the draft Allocation Schedule to Contributor, and Contributor shall consider these comments in good faith. Within 15 days after receipt of such comments, Contributor shall prepare, and submit to SEP, a final Allocation Schedule.

(c) The Parties understand and agreed that, prior to the Closing, SEP shall borrow (such borrowing, the “Transaction Debt”) an amount equal to the Cash Distribution (properly taking into account the possibility of a Post-Closing Adjustment Distribution by SEP) under indebtedness that constitutes an MLP GP Recourse Liability. The Parties have agreed to take such steps as may be appropriate to cause the proceeds of the Transaction Debt to be allocable to the Cash Distribution pursuant to Treasury Regulation Section 1.707-5(b)(1) and Temporary Treasury Regulation Section 1.163-8T. The Parties intend that the Cash Distribution paid to Contributor shall qualify as a “debt-financed transfer” not taken into account as part of a “disguised sale” of property contributed to SEP under Treasury Regulation Sections 1.707-3 and 1.707-5(b).

(d) During the greater of (i) the original term to maturity of the Transaction Debt (but in any event no longer than 10 years) and (ii) the period ending on the fourth anniversary of the Closing Date, the Parties shall ensure (and shall cause their respective Affiliates to ensure) that Contributor’s “allocable share” of the Transaction Debt (or any “refinancing” of such borrowing treated as the liability it refinances pursuant to Treasury Regulation Section 1.707-5(c)) will not be less than the entire outstanding principal balance of the Transaction Debt outstanding immediately after the Closing.

(e) The Parties shall act at all times in a manner consistent with the foregoing provisions of this Section 7.22, except with the prior written consent of Contributor or as otherwise required by applicable Law following a final determination by the U.S. Internal Revenue Service or a Government Entity with competent jurisdiction.

Section 7.23 SEP Equity Offerings. SEP shall not, and shall cause its subsidiaries not to, use SEP Restricted Equity Proceeds for any purposes other than the funding of capital expenditures of SEP or any of its subsidiaries (including any acquisitions, mergers or joint ventures).

Section 7.24 Net Worth of Contributor. Contributor will maintain a net value (as determined pursuant to the principles of Treasury Regulation Section 1.752-2(k)(2), applying those principles as if Contributor were a disregarded entity for federal income tax purposes) that is not less than the principal amount of the Transaction Debt outstanding immediately after the Closing, together with all other indebtedness of SEP that constitutes an MLP GP Recourse Liability, which amount will be reduced by principal payments by SEP on such indebtedness and which amount will not be increased by any new borrowings by SEP.

Section 7.25 Further Assurances. Each of the Parties shall execute and deliver, or shall cause to be executed and delivered, such documents and other instruments and shall take, or shall cause to be taken, such further actions as may be reasonably required to carry out the provisions of this Agreement and give effect to the Transactions.

All covenants and agreements that by their terms apply or are to be performed in their entirety on or prior to the Closing shall terminate at the Closing. The period during which any such representation and warranty survives is the “Survival Period” for such representation and warranty. Notwithstanding the foregoing, any representation or warranty that would otherwise terminate shall survive with respect to Losses in respect of which notice, in reasonable detail, is given pursuant to this Agreement prior to the end of the Survival Period for such representation or warranty until such Losses are finally resolved and paid. For the avoidance of doubt, Contributor’s obligations with respect to the Retained Liabilities shall survive indefinitely.

Section 10.2 Indemnification by Contributor.

(a) Subject to the limitations set forth in Section 10.4, Contributor hereby agrees that from and after the Closing it shall indemnify, defend and hold harmless, without duplication, SEP, its Affiliates (including the Companies) and their respective directors, officers, shareholders, trustees and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “SEP Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the SEP Indemnified Parties, to the extent arising out of:

(i) any breach of any representation or warranty made by Contributor in Article III or Article V of this Agreement for the period such representation or warranty survives;

(ii) any breach by Contributor of any covenant or agreement made by Contributor in this Agreement; and

(iii) the Retained Liabilities.

(b) For purposes of this Section 10.2, whether any representations and warranties have been breached, and the determination and calculation of any Losses resulting from such breach, shall be determined without giving effect to any qualification as to “materiality” (including the word “material” and the term “Material Adverse Effect”).

Section 10.3 Indemnification by SEP.

(a) Subject to the limitations set forth in Section 10.4, SEP hereby agrees that from and after the Closing it shall indemnify, defend and hold harmless Contributor and its Affiliates, directors, officers, shareholders, trustees and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “Contributor Indemnified Parties” and collectively with the SEP Indemnified Parties, the “Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the Contributor Indemnified Parties, to the extent arising out of:

(i) any breach of any representation or warranty made by SEP in Article VI for the period such representation or warranty survives; and

(ii) any breach of any covenant or agreement of SEP in this Agreement.

(b) For purposes of this Section 10.3, whether SEP has breached any of its representations and warranties herein, and the determination and calculation of any Losses resulting from such breach, shall be determined without giving effect to any qualification as to “materiality” (including the word “material” and the term “Material Adverse Effect”).

Section 10.4 Limitations.

(a) Except with respect to (i) Taxes or (ii) any Loss arising out of any breach of (A) any representation or warranty in Section 5.16 or (B) any of the Fundamental Representations, Contributor shall be liable to the SEP Indemnified Parties for any Losses with respect to the matters contained in Section 10.2(a)(i) unless and until the aggregate of all Losses therefrom for which Contributor would otherwise be liable exceeds an amount equal to $20 million less Losses claimed under the Securities Purchase Agreement or the Original Purchase Agreement, without duplication, and not recovered under either such agreement because and to the extent the “Deductible” under either such agreement had not been satisfied (the “Deductible”), after which Contributor shall only be liable for Losses in excess of the Deductible.

(b) Except with respect to (i) Taxes or (ii) any Loss arising out of any breach of (A) any representation or warranty in Section 5.16 or (B) any of the Fundamental Representations, Contributor shall not be liable to the SEP Indemnified Parties with respect to the matters contained in Section 10.2(a)(i) for any individual Loss (or series of related Losses arising from a common set of facts), except to the extent such individual Loss (or series of

related Losses arising from a common set of facts) exceeds $300,000 (the “Mini-Basket”), and any such individual Losses (or series of related Losses arising from a common set of facts) not in excess of the Mini-Basket will not be aggregated for purposes of calculating the Deductible in Section 10.4(a).

(c) In no event shall Contributor’s aggregate liability to the SEP Indemnified Parties for Losses with respect to the matters contained in Section 10.2(a)(i) exceed $156 million less Losses claimed under the Securities Purchase Agreement or the Original Purchase Agreement, without duplication, and recovered under either such agreement (the “Cap”), except with respect to (i) Taxes or (ii) any Loss arising out of any breach of (A) any representation or warranty in Section 5.16 or (B) any of the Fundamental Representations, in which case Contributor’s aggregate liability to SEP Indemnified Parties pursuant to Section 10.2(a)(i) for such Losses shall not exceed the Cash Distribution.

(d) In no event shall SEP’s aggregate liability to the Contributor Indemnified Parties for Losses with respect to matters contained in Section 10.3(a)(i) exceed $156 million, less Losses claimed and recovered under the Securities Purchase Agreement.

(e) Notwithstanding anything in this Agreement to the contrary, should any SEP Indemnified Party have a claim for indemnification for Losses hereunder and such Losses are subject to indemnification under the Original Purchase Agreement, then SEP shall cause each Company that suffered such Losses (if indemnified under the Original Purchase Agreement or, if not, then the other SEP Indemnified Parties) to seek to recover such Losses under the Original Purchase Agreement to the extent indemnification is available thereunder and no SEP Indemnified Parties shall be entitled to seek recovery hereunder for such Losses unless, and then only to the extent that, full recovery is not achieved pursuant to the Original Purchase Agreement. Any SEP Indemnified Party that asserts a claim for Losses under the Original Purchase Agreement shall seek to recover 100% of the Losses suffered by the applicable Company (and not just the Equity Percentage thereof) and SEP shall pay, or cause the applicable SEP Indemnified Party to pay, such recovered amounts to the applicable Company. As to any Losses claimed by an SEP Indemnified Party and suffered by a Company, 100% of such Losses (and not just the Equity Percentage thereof) shall be counted towards the Deductible and the Cap hereunder.

(f) Notwithstanding anything herein to the contrary, no Indemnified Party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Person or its Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement or the Original Purchase Agreement.

(g) Notwithstanding anything to the contrary in this Agreement, in no event shall an Indemnifying Party be liable under this Article X for any exemplary, punitive, special, consequential, incidental or indirect damages, including lost profits or diminution of value or any loss of goodwill or possible business after the Closing, whether actual or prospective, except to the extent any such damages are included in any Third-Party Claim against a SEP Indemnified Party for which such SEP Indemnified Party is entitled to indemnification under this Agreement.

(h) Each Indemnified Party shall use commercially reasonable efforts to mitigate their respective Losses upon and after becoming aware of any event or condition that would reasonably be expected to give rise to any Losses that are indemnifiable hereunder. In the event an Indemnified Party fails to so mitigate an indemnifiable Loss, the Indemnifying Party shall have no liability for any portion of such Loss that reasonably could have been avoided had the Indemnified Party made such efforts. Without limiting the generality of the foregoing, after an Indemnified Party acquires knowledge of any fact or circumstance that results in or reasonably would be expected to result in an indemnified Loss or a Third-Party Claim for which the Indemnifying Party may have Liability to such Indemnified Party, such Indemnified Party shall notify the Indemnifying Party promptly and implement such reasonable actions as the Indemnifying Party shall request in writing for the purposes of mitigating the possible Losses arising therefrom.

(i) Notwithstanding anything herein to the contrary, to the extent any SEP Indemnified Party other than the Companies has a claim under Section 10.2(a)(i) or under Section 7.8(a) for Losses suffered by the Companies, such SEP Indemnified Party shall only be entitled to recover the Equity Percentage of such Losses.

Section 10.5 Third-Party Claim Indemnification Procedures.

(a) In the event that any written claim or demand for which an Indemnifying Party may have liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a third party (other than those relating to Taxes, which are the subject of Section 7.8) (a “Third-Party Claim”) such Indemnified Party shall promptly, but in no event more than ten days following such Indemnified Party’s receipt of a Third-Party Claim, notify the party or parties from whom indemnification is sought (collectively, the “Indemnifying Party”) in writing of such Third-Party Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Third-Party Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”). However, the failure to give prompt notice will not affect the rights or obligations of the Indemnifying Party except and only to the extent that, as a result of such failure, the Indemnifying Party was prejudiced. The Indemnifying Party shall have 15 days (or such lesser number of days set forth in the Claim Notice as may be required by court proceedings in the event of a litigated matter) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third-Party Claim. For purposes of this Article X, any existing or future claims related to the Retained Liabilities shall be subject to the same procedures as Third-Party Claims.

(b) In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third-Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense at its expense. Once the Indemnifying Party has duly assumed the defense of a Third-Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ a single separate counsel of its choosing. The Indemnified Party shall

participate in any such defense at its expense unless the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and the Indemnified Party shall have reasonably concluded, based on the advice of outside counsel, that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case the Indemnified Party shall participate in such defense and employ separate counsel at the Indemnifying Party’s expense. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third-Party Claim on a basis that would result in (i) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates or (ii) a finding or admission of a violation of Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates.

(c) If the Indemnifying Party elects not to defend the Indemnified Party against a Third-Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, the Indemnified Party shall have the right, but not the obligation, to assume its own defense; it being understood that the Indemnified Party’s right to indemnification for a Third-Party Claim shall not be adversely affected by assuming the defense of such Third-Party Claim. The Indemnified Party shall not settle a Third-Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

(d) The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defense of a Third-Party Claim, including by providing access to each other’s relevant business records and other documents, and employees.

(e) The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of confidential information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third-Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges. For the avoidance of doubt, nothing in this Section 10.5 shall be construed as a waiver by an Indemnified Party or an Indemnifying Party of any privilege, including any privilege associated with separate counsel as described herein.

Section 10.6 Payments. The Indemnifying Party shall pay all amounts payable pursuant to this Article X, by wire transfer of immediately available funds, promptly following receipt from an Indemnified Party of a ▇▇▇▇, together with all accompanying reasonably detailed back-up documentation, for a Loss that is the subject of indemnification hereunder, unless the Indemnifying Party in good faith disputes the Loss, in which event it shall so notify the Indemnified Party (provided, that, in the event of a good faith dispute with respect to a Loss, the Indemnifying Party shall promptly pay the portion of such Loss, if any, that is not subject to dispute). In any event, the Indemnifying Party shall pay to the Indemnified Party, by wire transfer of immediately available funds, the amount of any Loss for which it is liable hereunder no later than 30 days following any final determination of such Loss and the Indemnifying Party’s liability therefor. A “final determination” shall exist when (a) the parties to the dispute have reached an agreement in writing, (b) a court of competent jurisdiction shall have entered a final and non-appealable order or judgment or (c) an arbitration or like panel shall have rendered a final non-appealable determination with respect to disputes the parties to such dispute have agreed to submit thereto.

Section 10.7 Characterization of Indemnification Payments. All payments made by an Indemnifying Party to an Indemnified Party in respect of any claim pursuant to Section 10.2 or Section 10.3 hereof shall be treated as adjustments to the Cash Distribution to the maximum extent permitted by applicable Tax Law.

Section 10.8 Adjustments to Losses.

(a) Insurance. In calculating the amount of any Loss, the proceeds actually received by the Indemnified Party or any of its Affiliates under any insurance policy or pursuant to any claim, recovery, settlement or payment by or against any other Person, net of any actual costs or expenses incurred in connection with securing or obtaining such proceeds, shall be deducted. In the event that an Indemnified Party has any rights against a third party with respect to any occurrence, claim or Loss that results in a payment by an Indemnifying Party under this Article X, such Indemnifying Party shall be subrogated to such rights to the extent of such payment; provided that until the Indemnified Party recovers full payment of the Loss, any and all claims of the Indemnifying Party against any such third party on account of said indemnity payment are hereby expressly made subordinate and subject in right of payment to the Indemnified Party’s rights against such third party. Without limiting the generality or effect of any other provision hereof, each Indemnified Party and Indemnifying Party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

(b) Cash Distribution Adjustment. In calculating the amount of any Loss for which SEP is entitled to indemnification hereunder, the amount of any reserve or other negative provision related to such Loss shall be deducted to the extent reflected in the Final Statement and taken into account for any adjustment to the Cash Distribution in accordance with Section 2.3 and Section 2.4.

(c) Taxes. In calculating the amount of any Loss, there shall be deducted an amount equal to any Tax benefit (including the utilization of a Tax loss or Tax credit carried forward) as a result of such Loss by the party claiming such Loss. The amount of adjustment for any such Tax benefit shall equal (i) in the case of a Tax deduction, (A) the amount of the Tax deduction multiplied by (B) the applicable combined federal, state and provincial corporate income tax rates in effect for the year in which the applicable indemnity payment is made or (ii) in the case of a Tax credit, 100%. In the case of any Tax deduction that will be recognized, or any Tax credit that will be utilized, in taxable years after the year in which the indemnity payment is made, the Tax benefit shall be discounted using a discount rate equal to 5%.

(d) Reimbursement. If an Indemnified Party recovers an amount from a third party in respect of a Loss that is the subject of indemnification hereunder after all or a portion of such Loss has been paid by an Indemnifying Party pursuant to this Article X, the Indemnified Party shall promptly remit to the Indemnifying Party the amount, if any, by which (i) the sum of (A) the amount paid by the Indemnifying Party to such Indemnified Party in respect of such Loss plus (B) the amount received from the third party in respect thereof, exceeds (ii) the full amount of the Indemnifying Party’s portion of such Loss.

Section 10.9 Remedies; Exclusive Remedy. Except in the case of fraud and as otherwise provided in Section 11.9, the rights and remedies under this Article X are exclusive and in lieu of any and all other rights and remedies that the Contributor Indemnified Parties may have against SEP or that the SEP Indemnified Parties may have against Contributor under this Agreement or otherwise with respect to the Companies, the Contributed Interests or any breach of any representation or warranty or any failure to perform any covenant or agreement set forth in this Agreement. Each of the Parties expressly waives any and all other rights, remedies and causes of action it or its Affiliates may have against the other Party and its respective Affiliates, now or in the future under any Law with respect to the Transactions. The remedies expressly provided in this Agreement shall constitute the sole and exclusive basis for and means of recourse between the Parties with respect to the Transactions.

Section 10.10 Tax Indemnification. To the extent that Contributor or SEP may be liable for indemnification for any Taxes under both Section 7.8 and this Article X, Contributor or SEP, as applicable, shall only be liable under Section 7.8.

Section 11.2 Amendment; Waiver. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by each Person signatory hereto, or in the case of a waiver, by the Person against whom the waiver is to be effective. No failure or delay by any Person in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law except as otherwise specifically provided in Article X hereof.

Section 11.3 No Assignment or Benefit to Third Parties. This Agreement shall be binding upon and inure to the benefit of SEP and Contributor and their respective successors, legal representatives and permitted assigns. No Party may assign any of its rights or delegate any of its obligations under this Agreement (for the avoidance of doubt, no merger or sale of securities of any Party or any entity that directly or indirectly controls any Party shall constitute an assignment hereunder), without the prior written consent of the others, except as provided in Section 11.5, and any attempted or purported assignment in violation of this Section 11.3 shall be null and void; provided that, after the Closing, (a) SEP may, in its sole discretion, without the consent of Contributor assign all or a portion of its rights and/or obligations under this Agreement to an Affiliate of SEP and (b) Contributor may, without the consent of SEP, assign all or a portion of its rights and/or obligations under this Agreement to an Affiliate; provided that, in either case, (i) such assignment shall not relieve the assigning party of its obligations hereunder, (ii) such assignment shall not have any adverse tax consequence to the non-assigning party or parties and (iii) the assigning Person shall within ten Business Days of such assignment notify all

parties to this Agreement about such assignment, including providing copies of the documentation pursuant to which such assignment was effectuated. From and after the Closing, each Person that is an Indemnified Party but not a party to this Agreement, shall be an express third-party beneficiary of Section 7.14. Except as set forth in the immediately preceding sentence, nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties to this Agreement and their respective successors and permitted assigns, any rights or remedies under or by reason of this Agreement.

Section 11.4 Entire Agreement. This Agreement (including all Schedules and Exhibits), and the other Transaction Documents contain the entire agreement among Contributor and SEP with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters.

Section 11.5 Fulfillment of Obligations. Any obligation of any Person signatory hereto to any other Person signatory hereto under this Agreement or any of the other Transaction Documents that is performed, satisfied or fulfilled completely by an Affiliate of such Person signatory hereto shall be deemed to have been performed, satisfied or fulfilled by such Person signatory hereto. Each party to each of the Transaction Documents shall cause its Subsidiaries and Affiliates to perform all actions, agreements and obligations set forth herein or therein requiring the performance of any such Subsidiary or Affiliate (including any entity that becomes a Subsidiary or Affiliate of such party on or after the date hereof).

Section 11.6 [Intentionally Omitted]

Section 11.7 Expenses. Except as otherwise expressly provided in this Agreement, whether or not the Transactions are consummated, all costs and expenses incurred in connection with this Agreement and the Transactions shall be borne by the Person signatory hereto incurring such costs and expenses.

Section 11.8 Governing Law; Submission to Jurisdiction; Selection of Forum; Waiver of Trial by Jury.

(a) This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York, without regard to the conflict of laws rules thereof (other than New York General Obligations Law Sections 5-1401 and 5-1402).

(b) Except as otherwise set forth in this Agreement, all actions, suits or proceedings arising out of or relating to this Agreement, any of the other Transaction Documents or the consummation of the Transactions shall be heard and determined exclusively in United States District Court for the Southern District of New York or any federal court sitting in the Borough of Manhattan of The City of New York; provided, however, that if such federal court does not have jurisdiction over such action, suit or proceeding, such action, suit or proceeding shall be heard and determined exclusively in any state court sitting in the Borough of Manhattan of The City of New York. Consistent with the preceding sentence, Contributor and SEP hereby (i) irrevocably submit to the exclusive jurisdiction of any federal or New York state court sitting in the Borough of Manhattan of The City of New York for the purpose of any action, suit or proceeding arising out of or relating to

this Agreement, any of the other Transaction Documents or the consummation of the Transactions brought by any of them, (ii) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such action, suit or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the action, suit or proceeding is brought in an inconvenient forum, that the venue of the action, suit or proceeding is improper, or that this Agreement, any of the other Transaction Documents or the Transactions may not be enforced in or by any of the above-named courts and (iii) irrevocably consent to and grant any such court exclusive jurisdiction over the person of such parties and over the subject matter of such action, suit or proceeding and agree that mailing of process or other papers in connection with any such action, suit or proceeding in the manner provided in Section 11.1 or in such other manner as may be permitted by applicable Law shall be valid and sufficient service thereof.

(c) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION, SUIT OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT, ANY OF THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS. EACH PARTY HEREBY (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHERS HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, ANY OF THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 11.8(C).

Section 11.9 Specific Performance. Each of the Parties acknowledges that its obligations hereunder are unique and that remedies at law, including monetary damages, will be inadequate in the event it should default in the performance of its obligations under this Agreement. Accordingly, in the event of any breach of any agreement, representation, warranty or covenant set forth in this Agreement, a Party, in the case of a breach by the other Party, shall be entitled to equitable relief, without the proof of actual damages, including in the form of an injunction or injunctions or orders for specific performance to prevent breaches of this Agreement and to order the defaulting Party to affirmatively carry out its obligations under this Agreement, and each of the Parties hereby waives any defense to the effect that a remedy at law would be an adequate remedy for such breach. Such equitable relief shall be in addition to any other remedy to which each of the Parties are entitled to at law or in equity as a remedy for such nonperformance, breach or threatened breach. Each of the Parties hereby waives any requirements for the securing or posting of any bond with such equitable remedy. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by any of the Parties, each of whom expressly reserves any and all rights and remedies available to it at law or in equity in the event of any breach or default by the others under this Agreement prior to the Closing.

Section 11.10 Disclosure Schedules. Except with respect to any Supplemental Disclosure, which is governed by Section 7.5, the disclosure of any matter in any section or subsection of the Contributor Disclosure Schedule or the SEP Disclosure Schedule (collectively, the “Disclosure Schedules”), as applicable, shall be deemed to be a disclosure under the respective Person’s Disclosure Schedule for all purposes of this Agreement to which such matter could reasonably be expected to be pertinent. The mere inclusion of any item in any section or subsection of any of the Disclosure Schedules, as an exception to any representation or warranty or otherwise shall not be deemed to constitute an admission by any of the Parties, as applicable, or to otherwise imply, that any such item has had or is reasonably likely to have, individually or in the aggregate, a Material Adverse Effect or otherwise represents an exception or material fact, event or circumstance for the purposes of this Agreement, that such item meets or exceeds a monetary or other threshold specified for disclosure in this Agreement or that such item represents a determination that the Transactions require the consent of any third party. The sections or subsections of each Disclosure Schedule are arranged in sections corresponding to the numbered and lettered sections and subsections of this Agreement. Matters disclosed in any section or subsection of any of the Disclosure Schedules are not necessarily limited to matters that are required by this Agreement to be disclosed therein. Such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature or impose any duty or obligation to disclose any information beyond what is required by this Agreement, and disclosure of such additional matters shall not affect, directly or indirectly, the interpretation of this Agreement or the scope of the disclosure obligations hereunder. To the extent cross-references are set forth in any section or subsection of any of the Disclosure Schedules, such cross-references are intended solely for convenience and are by no means intended as a statement of limitation as to where disclosure is relevant or appropriate. The reference to any Contract or other documents or materials in any section or subsection of any of the Disclosure Schedules shall be deemed to incorporate by reference, for all purposes set forth in this Section 11.10 and the remainder of this Agreement, all terms and conditions of, and schedules and annexes to, such Contract or other document to the extent made available, prior to the date of this Agreement, to SEP and its Representatives or Contributor and its Representatives, as applicable. Headings inserted in the sections or subsections of any of the Disclosure Schedules are for convenience of reference only and shall to no extent have the effect of amending or changing the express terms of the sections or subsections as set forth in this Agreement.

Section 11.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, and all of which shall constitute one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

Section 11.12 Headings. The heading references herein and the table of contents hereof are for convenience purposes only, and shall not be deemed to limit or affect any of the provisions hereof.

Section 11.13 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the

application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 11.14 Action by SEP. With respect to any action (including any case where the agreement of, or selection by, SEP is required), notice, consent, approval or waiver that is required to be taken or given or that may be taken or given by SEP prior to or after the Closing Date with respect to, or in connection with, the subject matter hereof, such action, notice, consent, approval or waiver shall be taken or given by the Conflicts Committee on behalf of SEP.
