To the extent that amounts are so withheld and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. If withholding is taken in Parent Common Units, Parent, Merger Sub or the Exchange Agent (as applicable) shall be treated as having sold such Parent Common Units for an amount of cash equal to the fair market value of such Parent Common Units at the time of such deemed sale.

Nothing in this Section 5.4 shall prohibit the Partnership, or the GP Board, directly or indirectly through any officer, employee or Representative, from informing any person that the Partnership is party to this Agreement and informing such person of the restrictions that are set forth in this Section 5.4.

(b) Following the execution of this Agreement, each of the Partnership and the General Partner shall, and each of them shall cause their respective Subsidiaries, and the respective directors, officers, employees of the Partnership, the General Partner and such Subsidiaries to, and shall use its reasonable best efforts to cause the Representatives of the Partnership, the General Partner and such Subsidiaries to, immediately cease and terminate any discussions existing as of the date of this Agreement between the Partnership or any of its Subsidiaries or any of their respective officers, directors, employees or Representatives and any person (other than Parent, Merger Sub, GP Merger Sub or any of their respective officers, directors, employees or Representatives) that relate to any Acquisition Proposal.

(c) As used in this Agreement:

(i) “Acquisition Proposal” means any bona fide offer or proposal, whether or not in writing, received from or made public by a third party (other than an offer, proposal by Parent, Merger Sub, GP Merger Sub or their respective affiliates) relating to any Acquisition Transaction; and

Section 5.5 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Partnership shall prepare and file with the SEC the Form S-4, which will include the Combined Consent Statement/Prospectus. Each of Parent and the Partnership shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the LP Merger and the other transactions contemplated hereby. Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of Parent Common Units in the LP Merger, and the Partnership shall furnish all information concerning the Partnership and the holders of Partnership Common Units, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Combined Consent Statement/Prospectus will be made by Parent or the Partnership, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other party a reasonable opportunity to review and comment thereon. Parent or the Partnership, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Common Units issuable in connection with the LP Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Combined Consent Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Partnership, or any of their respective affiliates, officers or directors, is discovered by Parent or the Partnership that should be set forth in an amendment or supplement to any of the Form S-4 or the Combined Consent Statement/Prospectus, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the unitholders of the Partnership. For the avoidance of doubt, the Combined Consent Statement/Prospectus shall not be required to include a recommendation by the GP Board or the Conflicts Committee to the Partnership’s unitholders regarding this Agreement.

- 58 -

(b) The General Partner shall distribute to the Partnership’s unitholders the Combined Consent Statement/Prospectus as promptly as practicable after the Form S-4 is declared effective under the Securities Act. The Partnership shall (i) in accordance with the Partnership Organizational Documents, including Sections 13.6 and 13.11 of the Partnership Agreement, and applicable Law, take all actions to establish a record date (which will be as soon as reasonably practicable after the date upon which the Form S-4 is declared effective) for the purpose of determining Partnership unitholders entitled to deliver written consents, and (ii) in accordance with the Partnership Organizational Documents and applicable Law, distribute to the Partnership’s unitholders, the Combined Consent Statement/Prospectus, which shall include a form of consent that may be executed by the public unitholders of the Partnership Common Units in connection with the Requisite Unitholder Approval, as soon as reasonably practicable after the date upon which the Form S-4 becomes effective (and, in the case of the Sponsors, within 24 hours of the Form S-4 being declared effective).

Section 5.6 Equity-Based Awards.

(a) Each award of phantom units that corresponds to Partnership Common Units and vests solely based on the passage of time (including any Seconded Employee Phantom Awards), whether vested or unvested (“Partnership Phantom Units”), that is outstanding immediately prior to the Effective Time, shall, as of the Effective Time, be assumed by Parent and converted into a restricted unit award representing a contractual right to receive Parent Common Units or, in the case of Seconded Employees, the right to receive cash determined based on the value of Parent Common Units (each an “Assumed Restricted Unit Award”). Each such Assumed Restricted Unit Award shall be converted into a restricted unit award to receive a number of Parent Common Units (or the cash equivalent thereof, as applicable) equal to the product obtained by multiplying (x) the number of Partnership Common Units subject to such Partnership Phantom Unit immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up or down to the nearest whole Parent Common Unit. Each Assumed Restricted Unit Award shall otherwise be subject to the same terms and conditions (including as to vesting, distribution equivalent rights and issuance) as were applicable to the Partnership Phantom Unit immediately prior to the Effective Time.

(b) Each award of performance units that corresponds to Partnership Common Units, including Seconded Employee Performance Awards (each, a “Partnership Performance Award,” and together with the Partnership Phantom Units, the “Partnership Equity Awards”), that is outstanding and unvested as of the Effective Time, shall, as of the Effective Time, be measured as to performance as of the Effective Time (or a date reasonably proximate thereto) as determined in good faith by the GP Board and each such Partnership Performance Award shall, with respect to the number of Partnership Common Units that are considered earned with respect thereto based on the higher of actual performance or target shall, as of the Effective Time (the “Earned Performance Units”), be assumed by Parent and converted into an Assumed Restricted Unit Award, which shall have distribution equivalent rights and be eligible to vest solely based

- 59 -

on continued service at the end of the performance period that was originally applicable thereto; provided, however, that the Earned Performance Units will vest upon a “qualifying termination” and, to the extent applicable, will incorporate the provisions related to termination due to “retirement,” as provided in the Partnership Phantom Unit Awards. Notwithstanding the foregoing, with respect to Partnership Performance Awards granted in 2021, the number of Earned Performance Units shall be equal to the target number of units granted, regardless of performance. The number of Parent Common Units that are subject to such Assumed Restricted Unit Awards shall be equal to the number of Earned Performance Units with respect to the corresponding Partnership Performance Award, multiplied by the Exchange Ratio, rounded up or down to the nearest whole Parent Common Unit. Any performance units that correspond to Partnership Common Units that are not Earned Performance Units shall, upon the Effective Time, automatically be cancelled for no consideration.

(c) The General Partner shall take any and all actions reasonably necessary to effectuate the transactions contemplated by this Section 5.6 and such transactions shall be subject to compliance with Section 409A of the Code.

Section 5.7 Employee Matters.

(a) Following the Effective Time and until the first anniversary of the Closing Date (the “Continuation Period”), Parent shall, or shall cause one of its Subsidiaries to, provide the individuals who are employed by the Partnership, the General Partner or any of their Subsidiaries immediately before the Effective Time (the “Current Employees”) and who continue employment during such time period with (i) annual base salary or wages (as applicable) that are no less favorable than the annual base salary or wages (as applicable) provided to such Current Employees immediately prior to the Effective Time,(provided, that the foregoing shall not preclude Parent from implementing broad-based salary or other pay reduction programs following the date of this Agreement that are proportionate with reductions in salary or other pay for Parent’s other similarly situated employees), (ii) severance benefits that are no less favorable than the severance benefits set forth on Section 5.7(a) of the Partnership Disclosure Schedule, provided, however, that severance benefits for those certain employees subject to the Partnership’s February 2021 voluntary early retirement program (the “VERP”) and the other employees set forth on Section 5.7(a) of the Partnership Disclosure Schedule shall be as set forth in the VERP, and (iii) other compensation and employee benefits that are no less favorable than either, at Parent’s election, (A) the other compensation and employee benefits provided to similarly situated employees of Parent and its Subsidiaries, or (B) the other compensation and employee benefits provided to such Current Employees immediately prior to the Effective Time (excluding equity and equity-based compensation, defined benefit and supplemental pensions and retiree medical benefits).

(b) For purposes of vesting, eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies, and disability plans and policies, determining levels of benefits (but not, for the avoidance of doubt, for purposes of benefit accrual under any defined benefit pension plan) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Current Employees after the Effective Time (the “New Plans”), each Current Employee shall be credited with his or her years of service with the Partnership, the General Partner and their Subsidiaries and their respective predecessors and

- 60 -

prior employers before the Effective Time, to the same extent as such Current Employee was entitled, before the Effective Time, to credit for such service under any similar Partnership Benefit Plan in which such Current Employee participated or was eligible to participate immediately prior to the Effective Time, provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, (i) each Current Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is comparable to a Partnership Benefit Plan in which such Current Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Current Employee, Parent shall use commercially reasonable efforts to cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless and to the extent the individual, immediately prior to entry in the New Plans, was subject to the same such conditions under the comparable Old Plans, (iii) credit amounts paid under any Old Plan providing medical, dental, pharmaceutical and/or vision benefits under any corresponding New Plan for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the New Plan with respect to the plan year in which the Effective Time occurs, and (iv) assume and honor all vacation and paid time off days accrued by Current Employees prior to the Effective Time, including payment for such days upon termination of employment to the extent provided for under Law or the terms of the vacation and paid time off policies of the Partnership, the General Partner and their Subsidiaries, provided however, that the foregoing shall not restrict Parent from amending, modifying or terminating any applicable vacation or paid time off policy to the extent permitted by Law and (v) solely for vacation and paid time off policies, provide credit for years in the energy industry in addition to prior service credit with the Partnership, the General Partner and their Subsidiaries and their respective predecessors before the Effective Time. For purposes of this Agreement, “Benefit Plans” means any (i) “employee benefit plan” (within the meaning of Section 3(3) of ERISA), (ii) bonus, incentive or deferred compensation or equity or equity-based compensation plan, program, policy or arrangement, including employer stock and incentive plans, (iii) severance, change in control, employment, consulting, retirement, retention or termination plan, program, agreement, policy or arrangement or (iv) other compensation or benefit plan, program, agreement, policy, practice, contract, arrangement or other obligation, whether or not in writing and whether or not subject to ERISA, including all bonus, cash or equity-based incentive, deferred compensation, stock purchase, health, medical, dental, disability, accident, life insurance, or vacation, paid time off, perquisite, fringe benefit, severance, change of control, retention, employment, separation, retirement, pension, or savings, plans, programs, policies, agreements or arrangements.

(c) If the Effective Time occurs after July 1, 2021, then as soon as practicable following the Closing Date, Parent shall pay annual incentive bonuses for the 2021 calendar year in an amount equal to the higher of actual performance or target, prorated for the portion of the 2021 calendar year that occurs prior to the Closing Date, under the Partnership Short Term Incentive Plan. If the Effective Time occurs before July 1, 2021, then no pro-rated annual incentive bonuses will be paid in connection with the consummation of the transactions contemplated by this Agreement and the Current Employees will be eligible for annual bonuses for 2021 under the terms of Parent’s applicable short-term incentive plans as if they had been employed with Parent and its Subsidiaries from January 1, 2021.

- 61 -

(d) Parent shall establish and maintain or make provision for, the establishment or continuation of a health care and dependent care flexible spending account plans applicable to Current Employees and the election by any Current Employee under the Partnership Benefit Plan that includes flexible spending accounts will be continued as an election as if made under the applicable Benefit Plan containing flexible spending accounts from the beginning of the plan year of Partnership.

(e) If the Effective Time occurs prior to the end of a school semester, Parent acknowledges that the Partnership, the General Partner or their applicable Subsidiary or applicable successor thereof shall retain their obligations with respect to the Partnership’s tuition reimbursement program for the remainder of that semester and shall provide benefits thereunder in accordance with terms of such program to eligible Current Employees immediately prior to the Effective Time.

(f) If requested by Parent, subject to the terms of any such Partnership Benefit Plan and applicable Law, the Partnership or General Partner, as applicable, shall both (i) execute resolutions to terminate any Partnership Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement (a “Partnership 401(k) Plan”) and (ii) fully vest each Current Employee in his or her account balance in such Partnership 401(k) Plan, in each case, effective at least one day prior to the Closing Date (the “ERISA Effective Date”). Prior to the ERISA Effective Date, the Partnership shall provide Parent with executed resolutions of its or, as applicable, its Subsidiary’s Board of Directors authorizing such termination and amending any such Partnership 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws. The Partnership and the General Partner shall also take and/or cause their Subsidiaries to take such other actions in furtherance of the termination of each Partnership 401(k) Plan as Parent may reasonably require, including such actions as Parent may require prior to the Effective Time to support Parent obtaining a determination letter with respect to the termination of each Partnership 401(k) Plan following the ERISA Effective Date. Parent shall cause its Parent Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement to accept a direct rollover of any Current Employee’s benefits under the Partnership 401(k) Plan in cash and, if applicable, promissory notes.

(g) Parent acknowledges that the Partnership, the General Partner or their applicable Subsidiary or applicable successor thereof shall retain their obligations under the Partnership Deferred Compensation Plan and all duties and obligations thereunder. Parent will not cause the Partnership Deferred Compensation Plan to be terminated without payment of vested benefits accrued thereunder becoming payable to the participants therein.

(h) Parent hereby acknowledges that a “change of control” (or similar phrase) within the meaning of the Partnership Benefit Plans will occur at or prior to the Effective Time, as applicable. For the avoidance of doubt, Parent shall assume the Partnership Change of Control Plan and all duties and obligations of the Partnership thereunder. Parent will not terminate the Partnership Change of Control Plan prior to the end of the “Protected Period” as defined therein.

- 62 -

(i) Nothing in this Section 5.7 shall be construed as an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment or termination of any Benefit Plan in accordance with its terms. Nothing in this Section 5.7 shall limit the right of Parent, the Surviving Entities or any of their Subsidiaries to terminate the employment of any Current Employee at any time, subject to any rights to severance or other separation benefits accrued as of the applicable termination date under a Partnership Benefit Plan. Without limiting the generality of Section 8.13, the provisions of this Section 5.7 (including, for the avoidance of doubt, Section 5.7(j)) are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other person shall be a third-party beneficiary of this Agreement, and nothing herein shall be construed as an amendment to any Partnership Benefit Plan or other compensation or benefit plan or arrangement (including any Benefit Plan of Parent or its Subsidiaries) for any purpose.

(j) Subject to Section 5.7(k) below, Parent, the Partnership and the General Partner shall reasonably cooperate to take such actions as are necessary or desirable to provide for the termination of all Secondment Arrangements, and shall use commercially reasonable efforts to enter into an agreement or agreements with Ox or its applicable affiliate pursuant to which (i) the Secondment Arrangements shall be terminated upon or as soon as reasonably practicable after the Effective Time such that, as of such time of termination, the Seconded Employees shall be eligible to participate in the Benefit Plans of Parent or its applicable Subsidiary(ies) (the actual time of such termination, the “Secondment Termination Time”), excluding those obligations which by the terms of the Secondment Arrangements are intended to survive any such termination; (ii) one of Parent, the Partnership, the General Partner, or an applicable Subsidiary or successor of the foregoing shall have made an offer of employment, effective upon the Secondment Termination Time, to each Seconded Employee with such offers of employment on terms consistent with the provisions of Sections 5.7(a)-(d) and (h) but applying Section 5.7(a)-(d) and (h) with respect to the Seconded Employees by taking into account the compensation and benefits provided to the Seconded Employees by Ox or its applicable affiliate, and the Seconded Employees’ service with Ox or its applicable affiliate as of, immediately prior to the Effective Time (excluding, for the avoidance of doubt, equity and equity-based compensation, defined benefit and supplemental pensions and retiree medical benefits); and (iii) the Termination Costs and Severance Costs (as defined in the applicable Secondment Arrangement) of each Seconded Employee who does not become a Current Employee, or for which a Sponsor is otherwise responsible in respect of any Seconded Employee under the terms of the applicable Secondment Arrangement, will remain the obligation of the Partnership, the General Partner or their applicable Subsidiary or successor to the extent such Termination Costs and Severance Costs are the obligation of the Partnership, the General Partner or their applicable Subsidiary or successor pursuant to the terms of the applicable Secondment Arrangement. For the avoidance of doubt, subject to Section 5.7(k) below, it is expected that all such Seconded Employees who accept such offers and commence employment with Parent, the Partnership, the General Partner, or an applicable Subsidiary or successor of the foregoing shall be considered Current Employees for purposes of this Section 5.7. From and after the date of this Agreement, the General Partner and the Partnership shall, and shall use commercially reasonable efforts to cause any person employing a Seconded Employee to, reasonably cooperate with

- 63 -

Parent and provide Parent with such information regarding the Seconded Employees as is reasonably requested by Parent, including compensation information. Section 5.7(j) of the Partnership Disclosure Schedule sets forth, to the knowledge of the Partnership, a true and correct list of each Benefit Plan or other agreement maintained, sponsored, or entered into by a Sponsor (or an Affiliate thereof) pursuant to which any Termination Costs and Severance Costs would be incurred with respect to any Seconded Employee.

(k) Inactive Seconded Employees. With respect to any Seconded Employee who, as of the Closing, is not actively in service and on a disability or other approved leave of absence (excluding bona fide vacation) (an “Inactive Seconded Employee”), Ox or its applicable affiliate shall employ or shall continue to employ such Inactive Seconded Employee following the Closing and the applicable Secondment Arrangement will remain in effect with respect to and will continue to cover such Inactive Seconded Employee until he or she returns to active service or terminates employment with Ox or its applicable affiliate, and Parent’s, the Partnership’s, the General Partnership’s, or their applicable Subsidiary’s offer of employment to such Inactive Seconded Employee shall be for employment on the earliest reasonably practicable date following the date on which such Inactive Seconded Employee is able to return to work, and otherwise on the terms and conditions consistent with this Section 5.7(k); provided that such Inactive Seconded Employee is able to return to work within 180 days following the Closing Date, or such later time as required by applicable Law. For all purposes of this Agreement, in the case of any Inactive Seconded Employee who becomes a Current Employee, the date that such Inactive Seconded Employee commences (or is deemed to commence) employment with Parent or its Subsidiaries or the time of such commencement (or deemed commencement) of employment shall be substituted for the “Secondment Termination Time,” wherever such term appears, except where the context requires otherwise.

Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the General Partner, Partnership or any of their respective Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 5.11 is not prior to, or in substitution for, any such claims under any such policies.

- 68 -

(g) The obligations of Parent and the Surviving Entities under this Section 5.11 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.11 applies without the consent of such Indemnified Party.

any of their respective Representatives pursuant to any agreement, arrangement, contract, certificate, instrument, or other document relating to any such financing will be effective until the Effective Time, and none of the General Partner, the Partnership, nor any of its Subsidiaries will be required to take any action pursuant to any of the foregoing that is not contingent on the occurrence of the Closing or that must be effective before the Effective Time. Further, nothing in this Section 5.16 will require (1) the General Partner, the Partnership, its Subsidiaries, or their respective Representatives to execute, deliver or enter into, or perform any agreement, document or instrument, including any definitive financing document, with respect to any financing or adopt resolutions approving the agreements, documents and/or instruments pursuant to which any financing is obtained or pledge any collateral with respect to any financing prior to Closing or (2) any officer or Representative of the General Partner, the Partnership or any of its Subsidiaries to deliver any certificate or take any other action under this Section 5.16 that could reasonably be expected to result in personal liability to such officer or Representative, or (3) the Representatives of the General Partner, the Partnership or its Subsidiaries to deliver any legal opinions with respect to such financing.

ARTICLE VII.

TERMINATION

Section 7.1 Termination or Abandonment. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and abandoned at any time prior to the Effective Time:

(a) by the mutual written consent of the Partnership and Parent;

- 78 -

(b) by either the Partnership or Parent, if the LP Merger shall not have been consummated on or prior to November 30, 2021 (the “End Date”); provided, however, that if all of the conditions to Closing, other than any of the conditions set forth in Section 6.1(b) or Section 6.1(c), shall have been satisfied or shall be capable of being satisfied at such time, the End Date shall automatically be extended to February 28, 2022, which date shall thereafter be deemed to be the End Date; provided, further, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to a party if the failure of the Closing to occur by such date shall be due to the material breach by such party of any representation, warranty, covenant or other agreement of such party set forth in this Agreement;

(c) by either the Partnership or Parent, if an injunction or other Law shall have been entered, enacted or become effective permanently restraining, enjoining or otherwise prohibiting the consummation of the Mergers and such injunction or other Law has become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 7.1(c) shall not be available to a party if such injunction was due to the material breach by such party of any covenant or other agreement of such party set forth in this Agreement;

(d) by the Partnership, if Parent, Merger Sub or GP Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, Parent does not diligently attempt or ceases to diligently attempt to cure such breach or failure after receiving written notice from the Partnership describing such breach or failure in reasonable detail (provided that the Partnership is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

(e) by Parent, if the Partnership or the General Partner shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, the Partnership or the General Partner, as applicable, does not diligently attempt, or ceases to diligently attempt, to cure such breach or failure in such a manner that would make it reasonably likely that such breach or failure will be cured prior to the End Date, in each case after receiving written notice from Parent describing such breach or failure in reasonable detail (provided that Parent is not then in material breach of any representation, warranty, covenant or other agreement contained herein); and

(f) by Parent, if the Partnership or the General Partner shall have Willfully Breached any of its obligations under Section 5.4, which materially impedes, interferes with or hinders the consummation of the transactions contemplated hereby on or before the End Date.

- 79 -

Section 7.2 Effect of Termination. In the event of termination of this Agreement pursuant to Section 7.1, this Agreement shall terminate (except for the provisions of this Section 7.2, Section 7.3 and Article VIII), and there shall be no other liability on the part of the Partnership or Parent to the other, except, subject to Section 7.3, for liability arising out of or the result of, fraud or any Willful Breach of any covenant or agreement or Willful Breach of any representation or warranty in this Agreement occurring prior to termination or as provided for in the Confidentiality Agreement, in which case the aggrieved party shall be entitled to all rights and remedies available at law or in equity.

Section 7.3 Breakup Fee.

(a) If (i) this Agreement is terminated by Parent pursuant to Section 7.1(f) [Willful Breach], then the Partnership shall pay the Break-Up Fee to Parent, within three business days of such termination, by wire transfer of same day federal funds to the account specified by Parent.

(b) If (i) this Agreement is terminated by Parent pursuant to Section 7.1(e) [Breach of Representation or Failure to Perform Covenant] and (ii) prior to such termination and after the date of this Agreement, any person (other than Parent, Merger Sub or any of their respective affiliates) shall have made an Acquisition Proposal, which shall have been publicly announced or disclosed or otherwise communicated to the GP Board or any affiliate of the General Partner (including Caribou and Ox but excluding their respective affiliates (other than the Partnership and its Subsidiaries)) and not have been withdrawn prior to such termination and (iii) within 12 months after the date of such termination, the Partnership enters into a definitive agreement with respect to an Acquisition Proposal (or publicly approves or recommends to the unitholders of the Partnership or otherwise does not oppose, in the case of a tender or exchange offer, an Acquisition Proposal) or consummates an Acquisition Proposal, then the Partnership shall pay to Parent, within three business days of the first to occur of the events described in clause (iii), the Breakup Fee , by wire transfer of same day federal funds to the account specified by Parent.

(c) Solely for purposes of this Section 7.3, “Acquisition Transaction” shall have the meaning ascribed thereto in Section 5.4(c)(i), except that all references to “25% or more” shall be changed to “more than 50%.”

(d) As used in this Agreement, “Breakup Fee” means $97,500,000.

Upon payment of the Breakup Fee to Parent pursuant to Section 7.3(a) or Section 7.3(b), no parties shall have any further liability with respect to this Agreement or the transactions contemplated hereby to the Partnership or its unitholders or Parent or its unitholders, as applicable; provided that nothing herein shall release any party from liability arising out of or the result of fraud. The parties acknowledge and agree that in no event shall the Partnership be required to pay the Breakup Fee, as applicable, on more than one occasion. In addition, the parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement and are not a penalty, and that, without these agreements, neither party would enter into this Agreement. If the Partnership fails to pay promptly the amounts due pursuant to this Section 7.3, the Partnership will also pay to Parent interest on the unpaid amount under this Section 7.3, accruing from its due date, at an interest rate per annum equal to two percentage points in excess of the prime commercial lending rate quoted by The Wall Street Journal and the reasonable out-of-pocket expenses (including legal fees) in connection with any action taken to collect payment. Any change in the interest rate hereunder resulting from a change in such prime rate will be effective at the beginning of the date of such change in such prime rate.

Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given shall be deemed to be receipt of the notice as of the date of such rejection, refusal or inability to deliver.

Section 8.8 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated by any of the parties hereto without the prior written consent of the other parties; provided, however, that Parent may assign its right to receive the Breakup Fee under Section 7.3 to one or more wholly owned direct or indirect subsidiaries of Parent without the prior written consent of the Partnership, so long as such assignment does not delay the Closing. Subject to the first sentence of this Section 8.8, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Any purported assignment not permitted under this Section shall be null and void.

Section 8.9 Severability. Any term or provision of this Agreement which is held to be invalid or unenforceable in a court of competent jurisdiction shall be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement. Upon such a determination, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transaction contemplated hereby are consummated as originally contemplated to the fullest extent possible. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

Section 8.10 Entire Agreement. This Agreement together with the exhibits hereto, schedules hereto, the Support Agreements and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof and thereof, and this Agreement is not intended to grant standing to any person other than the parties hereto.

Section 8.11 Amendments; Waivers. At any time prior to the Effective Time, 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 the Partnership, Parent, the General Partner, Merger Sub and GP Merger Sub or, in the case of a waiver, by the party against whom the waiver is to be effective; provided, however, after the Sponsor Written Consent has been obtained, if any such amendment or waiver shall (a) be materially adverse to the Sponsors, the effectiveness of such amendment or waiver shall be subject to the approval of the Sponsors and (b) by applicable Law or in accordance with the rules and regulations of the NYSE require further approval of the unitholders of the Partnership, the effectiveness of such amendment or waiver shall be subject to the approval of the unitholders of the Partnership; provided, further,

- 84 -

that no provision of this Agreement may be amended or waived without the prior consent of the Conflicts Committee. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 8.12 Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever. The table of contents to this Agreement is for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 8.13 Third-Party Beneficiaries. Each of Parent, Merger Sub, GP Merger Sub, the Partnership and the General Partner agrees that (a) their respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the Partnership or Parent, Merger Sub and GP Merger Sub, as applicable, in accordance with and subject to the terms of this Agreement, and (b) except for (i) the provisions of Section 5.11, (ii) the right of the Partnership’s unitholders to receive the LP Merger Consideration on the terms and conditions of this Agreement, this Agreement is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. Notwithstanding the foregoing, each of Parent, Merger Sub, GP Merger Sub, the Partnership and the General Partner expressly agrees that each Sponsor is intended to, and shall, be a third party beneficiary of the representations, warranties and covenants and agreements of the parties set forth in this Agreement, which representations, warranties and covenants and agreements shall not be amended, modified or waived in any way that materially adversely affects a Sponsor without the prior written consent of such Sponsor. For the avoidance of doubt, the parties agree that without limiting the prior sentence, any amendment or modification of, or the waiver of rights under, Sections 2.1(a), 2.1(b), 5.1(b) (but only if such amendment or modification further restricts the conducts of the Partnership or its Subsidiaries businesses) 5.8, 5.11, 5.14, 5.18, 6.1, 6.2, 7.1, 7.2, 7.3, 8.13 or 8.14 of this Agreement shall be deemed to materially adversely affect the Sponsors.

Section 8.14 No Recourse to Sponsors. Notwithstanding anything to the contrary contained herein, each of Parent, Merger Sub, GP Merger Sub, the Partnership and the General Partner expressly agrees that the Sponsors shall have no liability to any person in connection with this Agreement or, except as expressly set forth in their respective Support Agreements and subject to the terms and conditions thereof, the transactions contemplated hereby, and none of the parties to this Agreement shall make any claims whatsoever against either Sponsor or its affiliates (other than the Partnership and the General Partner) or their respective representatives in connection with this Agreement or the transactions contemplated hereby other than, if applicable, enforcement by Parent of the Support Agreements in accordance with their terms.

Section 8.14 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement,

- 85 -

unless the context otherwise requires. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant thereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. References in this Agreement to specific laws or to specific provisions of laws shall include all rules and regulations promulgated thereunder, and any statute defined or referred to herein or in any agreement or instrument referred to herein shall mean such statute as from time to time amended, modified or supplemented, including by succession of comparable successor statutes. Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.

Section 8.15 Definitions.

REGISTRATION RIGHTS

Section 2.01    Shelf Registration.

(a)    As promptly as practicable after the date hereof, and in any event within five days following the date hereof, the Parent shall use commercially reasonable efforts to prepare and file a Registration Statement to permit the public resale of the Registrable Units held by the Holders from time to time as permitted by Rule 415 of the Securities Act (a “Shelf Registration Statement”) in accordance with the provisions of this Agreement; provided, that the Parent shall only be obligated to prepare and file one such Shelf Registration Statement pursuant to this Section 2.01 on behalf of the Holders. The Parent shall effect such Shelf Registration Statement using a registration statement on Form S-3 whenever the Parent is eligible to do so, and shall use an Automatic Shelf Registration Statement (as defined in Rule 405 of the Securities Act) if it is a well-known seasoned issuer (as defined under Rule 405 of the Securities Act). The Parent shall use its commercially reasonable efforts to (i) cause such Shelf Registration Statement to be declared effective as soon as practicable after the filing thereof and (ii) keep such Shelf Registration Statement continuously effective during the Effectiveness Period.

(b)    At any time and from time to time following the effectiveness of the Shelf Registration Statement required by Section 2.01(a), any Holder may request to sell all or a portion of their Registrable Units in an underwritten offering that is registered pursuant to such Shelf Registration Statement, including a Block Trade (a “Shelf Underwritten Offering”), provided that such Holder(s) reasonably expect(s) to sell Registrable Units yielding aggregate gross proceeds of at least $200,000,000 from such Shelf Underwritten Offering. All requests for a Shelf Underwritten Offering shall be made by giving written notice to the Parent (the “Shelf Takedown

4

Notice”). Each Shelf Takedown Notice shall specify the approximate number of Registrable Units proposed to be sold in the Shelf Underwritten Offering and the expected price range (net of underwriting discounts and commissions) of such Shelf Underwritten Offering. Within three Business Days after receipt of any Shelf Takedown Notice, the Parent shall give written notice of such requested Shelf Underwritten Offering to all other Holders of Registrable Units (the “Parent Shelf Takedown Notice”) and, subject to the provisions of Section 2.01(d), shall include in such Shelf Underwritten Offering all Registrable Units with respect to which the Parent has received written requests for inclusion therein within five Business Days after sending the Parent Shelf Takedown Notice, or, in the case of a Block Trade, as provided in Section 2.03. The Parent shall enter into an underwriting agreement in a form as is customary in underwritten offerings of securities by the Parent with the managing underwriter selected by the Holder(s) requesting such Shelf Underwritten Offering (which managing underwriter shall be subject to approval of the Parent, which approval shall not be unreasonably withheld) and shall take all such other reasonable actions as are requested by the managing underwriter in order to expedite or facilitate the disposition of such Registrable Units in accordance with the terms of this Agreement. In connection with any Shelf Underwritten Offering contemplated by this Section 2.01(b), subject to Section 2.04, the underwriting agreement into which each Holder and the Parent shall enter shall contain such representations, covenants, indemnities and other rights and obligations as are customary in underwritten offerings of securities by the Parent. Notwithstanding any other provision of this Agreement to the contrary, CenterPoint Energy, Inc. (“CenterPoint”) may not demand more than five Shelf Underwritten Offerings and OGE Energy Corp. (“OGE”) may not demand more than three Shelf Underwritten Offerings, provided that there shall be no more than three Shelf Underwritten Offerings in any 12-month period, of which, no more than two such Shelf Underwritten Offerings in any 12-month period may be demanded by CenterPoint and no more than one such Shelf Underwritten Offering in any 12-month period may be demanded by OGE unless either CenterPoint or OGE shall assign to the other one or more such Shelf Underwritten Offerings in any 12-month period.

(c)    If the Parent or any of its Affiliates is conducting or actively pursuing a securities offering of Parent Common Units (other than in connection with any at-the-market offering or similar continuous offering program), then the Parent may suspend any Holder’s right to require the Parent to conduct a Shelf Underwritten Offering pursuant to Section 2.01(b); provided, however, that the Parent may only suspend such Holder’s right to require the Partnership to conduct a Shelf Underwritten Offering once in any six-month period and in no event for a period that exceeds an aggregate of 60 days in any 180-day period or 90 days in any 365-day period.

(d)    In connection with any Shelf Underwritten Offering, if the managing underwriter advises the Parent that in its opinion the number of Registrable Units proposed to be included in such offering exceeds the maximum number of Parent Common Units that can be sold in such offering without being likely to materially delay or jeopardize the success or timing of the offering (including the price per unit of the Parent Common Units proposed to be sold in such offering), the Parent shall include in such Shelf Underwritten Offering the Registrable Units of the Holders pro rata based on the total amount of Registrable Units requested to be included therein by each such Holder that can be sold without exceeding such maximum number of Parent Common Units.

Section 2.02    Piggyback Registration.

(a)    If the Parent proposes to file with the SEC (i) a Registration Statement to register any Parent Common Units for an underwritten offering under the Securities Act or (ii) a prospectus supplement relating to the sale of Parent Common Units pursuant to an effective “automatic” registration statement, so long as the Parent is a WKSI at such time or, whether or not the Parent is a WKSI, so long as the Registrable Units were previously included in the underlying shelf Registration Statement or are included on an effective Registration Statement, in each case for its own account and/or for another Person (such other Person, an “Other Holder”), other than on a registration statement on Form S-8 or Form S-4, and the form of registration statement to be used may be used for a registration of Registrable Units (a “Piggyback Registration”), the Parent shall give five Business Days’ written notice to the Holders of its intention to file such registration statement and, subject to this Section 2.02, shall include in such Registration Statement and in any offering of Parent Common Units to be made pursuant to such Registration Statement all Registrable Units with respect to which the Parent has received a written request for inclusion therein from any Holder within three Business Days after such Holder’s receipt of the Parent’s notice. The Parent shall have no obligation to proceed with any Piggyback Registration and may abandon, terminate and/or withdraw such registration for any reason at any time prior to the pricing thereof. Any Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Units in such Piggyback Registration by giving written notice to the Parent of such withdrawal at least two Business Days prior to the time of the public announcement of the Parent’s intention to conduct such underwritten offering.

(b)    If a Piggyback Registration is initiated for an underwritten offering on behalf of the Parent or any Other Holder and the managing underwriter(s) advise the Parent that in their opinion the number of Parent Common Units proposed to be included in such offering exceeds the number of Parent Common Units that can be sold in such offering without being likely to materially delay or jeopardize the success or timing of the offering (including the price per unit of the Parent Common Units proposed to be sold in such offering), the Parent shall include in such registration and offering (i) first, the number of Parent Common Units that the Parent or, if such offering was initiated by any Other Holder, any Other Holder proposes to sell and (ii) second, the number of Parent Common Units requested to be included therein by the Holders that have elected to include Registrable Units in such Piggyback Registration, pro rata among all such Holders on the basis of the number of Parent Common Units requested to be included therein by all such Holders or as such Holders and the Parent may otherwise agree and (iii) third, the number of Parent Common Units requested to be included therein by other unitholders of Parent, pro rata among all such unitholders on the basis of the number of Parent Common Units requested to be included therein by all such unitholders or as such unitholders and the Parent may otherwise agree. If the number of Parent Common Units that can be so sold is less than the number of Parent Common Units proposed to be sold by the Parent or any Other Holder pursuant to the Piggyback Registration, the amount of Parent Common Units to be sold shall be fully allocated to the Parent or such Other Holder, as applicable.

(c)    In any Piggyback Registration under Section 2.02(b), the Parent shall have the right to select the underwriter or underwriters for any offering conducted pursuant thereto.

6

(d)    None of the Holders shall sell any Registrable Units in any offering pursuant to a Piggyback Registration unless it (i) agrees to sell such Registrable Units on the basis provided in the underwriting arrangements approved by the Parent and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lockups and other documents reasonably required of such Holder under the terms of such arrangements.

Section 2.03     Block Trades. Notwithstanding the foregoing, at any time and from time to time when a Shelf Registration Statement is on file with the SEC and is effective, if a Holder wishes to engage in an underwritten or other coordinated registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), with a total offering price reasonably expected to be at least, in the aggregate, either (x) $50 million or (y) all remaining Registrable Units held by the Holder, then notwithstanding the time periods provided for in Section 2.01(b), such Holder need only to notify the Parent of the Block Trade at least five Business Days prior to the day such offering is to commence and the Parent shall use commercially reasonable efforts to facilitate such Block Trade; provided that the Holders representing a majority of the Registrable Units wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Parent and any underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade.

Section 2.04    Suspension Periods. The Parent may delay the filing or effectiveness of, or by written notice to the Holders suspend the use of, a Shelf Registration Statement in conjunction with a registration of Registrable Units pursuant to Section 2.01, but in each such case only if the Parent determines in good faith that (a) such delay would enable the Parent to avoid disclosure of material information, the disclosure of which at that time would be adverse to the Parent (including by interfering with, or jeopardizing the success of, any pending or proposed acquisition, disposition or reorganization), (b) such filing or use would render the Parent unable to comply with applicable securities Laws or (c) obtaining any financial statements (including required consents) required to be included in any such Shelf Registration Statement (or incorporated therein) would be impracticable. Any period during which the Parent has delayed the filing, effectiveness or use of a Registration Statement pursuant to this Section 2.04 is herein called a “Suspension Period.” During any such Suspension Period, the Holder will be entitled to withdraw any request for a Shelf Underwritten Offering and, if such request is withdrawn, such Shelf Underwritten Offering will not count as a Shelf Underwritten Offering. In no event shall the number of days covered by (i) any one Suspension Period exceed 60 days and (ii) all Suspension Periods in any 360 day period exceed 150 days. The Holders shall keep the existence of each Suspension Period confidential.

Section 2.05    Obligations of the Parent and the Holders. (a) Whenever required under Section 2.01 to use commercially reasonable efforts to effect the registration of any Registrable Units, the Parent shall:

(i)    as expeditiously as possible, subject to the other provisions of this Agreement, prepare and file with the SEC a Registration Statement with respect to such Registrable Units and cause such Registration Statement to be declared effective (or become automatically effective) under the Securities Act;

(c)    The Holders agree by having their Parent Common Units treated as Registrable Units hereunder that, upon being advised in writing by the Parent of the occurrence of an event pursuant to Section 2.05(a)(vii) when the Parent is entitled to do so pursuant to Section 2.04, the Holders will immediately discontinue (and direct any other Persons making offers and sales of Registrable Units to immediately discontinue) offers and sales of Registrable Units pursuant to any Registration Statement until it is advised in writing by the Parent that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 2.05(a)(vii), and, if so directed by the Parent, the Holders will deliver to the Parent all copies, other than permanent file copies then in the Holders’ possession, of the Prospectus covering such Registrable Units current at the time of receipt of such notice.

Section 2.07    Expenses of Registration. All expenses incurred in connection with any Registration pursuant to Section 2.01 and any Registration pursuant to Section 2.02 of this Agreement, and any offerings under the Registration Statements filed in such Registrations, excluding underwriters’ discounts and commissions, but including without limitation all registration, filing and qualification fees, word processing, duplicating, printers’ and accounting fees (including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance), fees of the Financial Industry Regulatory Authority, Inc. or listing fees, messenger and delivery expenses, all fees and expenses of complying with state securities or blue sky laws (including the reasonable fees and disbursements of counsel for the underwriters in connection with blue sky qualifications), and the fees and disbursements of counsel for the Parent (“Registration Expenses”), shall be paid by the Parent.

Section 2.08    Indemnification. The Parent shall indemnify, to the fullest extent permitted by Law, the Holders and their respective directors, officers, affiliates, employees, agents and each Person who controls such Holder (within the meaning of the Securities Act or the Exchange Act), against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable attorneys’ fees) relating to the Registrable Units arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as the same are made in reliance and in conformity with information furnished in writing to the Parent by any Holder or to the Parent by any participating underwriter for use in connection with any such Registration Statement or Prospectus, or amendment or supplement thereto. In connection with an underwritten offering in which any Holder participates conducted pursuant to a registration effected hereunder, the Parent shall indemnify each participating underwriter to the same extent as provided above with respect to the indemnification of the Holders.

(a)    In connection with any Registration Statement in which any Holder is participating, such Holder shall furnish to the Parent in writing such information as the Parent reasonably

11

requests for use in connection with any such Registration Statement or Prospectus, or amendment or supplement thereto, and such Holder shall indemnify to the fullest extent permitted by Law, the Parent and its respective directors, officers, affiliates, employees, agents and each Person who controls Parent (within the meaning of the Securities Act or the Exchange Act), against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement or Prospectus, or any amendment or supplement thereto, or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information furnished in writing to the Parent by or on behalf of such participating Holder expressly for use therein. In connection with an underwritten offering conducted pursuant to a registration effected hereunder, the participating Holders shall indemnify each participating underwriter to the same extent as provided above with respect to the indemnification of the Parent.

(b)    Any Person entitled to indemnification hereunder shall (1) give prompt written notice to the indemnifying Person of any claim with respect to which it seeks indemnification and (2) permit such indemnifying Person to assume the defense of such claim with counsel reasonably satisfactory to the indemnified Person. Failure to so notify the indemnifying Person shall not relieve it from any liability that it may have to an indemnified Person. The indemnifying Person shall not be subject to any liability for any settlement made by the indemnified Person without its consent (but such consent will not be unreasonably withheld). An indemnifying Person who is entitled to, and elects to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to one local counsel) for all Persons indemnified (hereunder or otherwise) by such indemnifying Person with respect to such claim (and all other claims arising out of the same circumstances), unless in the reasonable judgment of any indemnified Person there may be one or more legal or equitable defenses available to such indemnified Person that are in addition to or may conflict with those available to another indemnified Person with respect to such claim, in which case each such indemnified Person shall be entitled to use separate counsel. The indemnifying Person shall not consent to the entry of any judgment or enter into or agree to any settlement relating to a claim or action for which any indemnified Person would be entitled to indemnification by any indemnified Person hereunder unless such judgment or settlement imposes no ongoing obligations on any such indemnified Person and includes as an unconditional term the giving, by all relevant claimants and plaintiffs to such indemnified Person, of a release, reasonably satisfactory in form and substance to such indemnified Person, from all liabilities in respect of such claim or action for which such indemnified Person would be entitled to such indemnification.

(c)    The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer or director of such indemnified Person and shall survive the transfer of securities and the termination of this Agreement, but only with respect to offers and sales of Registrable Units made before such termination.

12

(d)    If the indemnification provided for in or pursuant to this Section 2.08 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying Person, in lieu of indemnifying such indemnified Person, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying Person, on the one hand, and of the indemnified Person, on the other hand, in connection with the statements or omissions which result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying Person, on the one hand, and of the indemnified Person, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying Person or by the indemnified Person, and by such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

Section 2.09    Lockup. The Holders shall, in connection with any underwritten offering of Parent Common Units, upon the request of the underwriters managing the underwritten offering of Parent Common Units, agree in writing not to effect any sale, disposition or distribution of any Registrable Units (other than that included in such Registration) without the prior written consent of the underwriters for such period of time as such underwriters may specify, but in no event to exceed 10 days prior to the date of the Prospectus and 60 days from the date of the Prospectus.

Section 6.14    Severability. To the fullest extent permitted by law, any term or provision of this Agreement, or the application thereof, that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is illegal, void, invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any illegal, void, invalid or unenforceable term or provision with a term or provision that is legal, valid and enforceable and that comes closest to expressing the intention of the illegal, void, invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. To the fullest extent permitted by law, in the event such court does not exercise the power granted to it in the prior sentence, the parties hereto shall replace such illegal, void, invalid or unenforceable term or provision with a legal, valid and enforceable term or provision that will achieve, to the extent possible, the original economic, business and other purposes of such illegal, void, invalid or unenforceable term as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.15    Expenses. Except as otherwise expressly provided herein or in the Merger Agreement, all costs and expenses incurred in connection with this Agreement and the actions contemplated hereby shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

Section 6.16    Successors and Assigns; Third Party Beneficiaries.

(a)    Except in connection with a Permitted Transfer, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto; provided, however, that Parent, Merger Sub and GP Merger Sub may transfer or assign their rights

and obligations under this Agreement, in whole or in part or from time to time in part, to one or more of their affiliates to which their rights are assigned pursuant to the terms of the Merger Agreement at any time. Any assignment in violation of the foregoing shall be null and void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b)    This Agreement is not intended to and shall not confer upon any person (other than the parties hereto) any rights or remedies hereunder.

Section 6.8    Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

(a)    THIS AGREEMENT AND THE AGREEMENTS, INSTRUMENTS AND DOCUMENTS CONTEMPLATED HEREBY AND ALL DISPUTES BETWEEN THE PARTIES UNDER OR RELATING TO THIS AGREEMENT OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION, WHETHER IN CONTRACT, TORT OR OTHERWISE, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH

9

THE LAWS OF THE STATE OF DELAWARE (WITHOUT REFERENCE TO SUCH STATE’S PRINCIPLES OF CONFLICTS OF LAW). THE DELAWARE COURT OF CHANCERY (AND IF THE DELAWARE COURT OF CHANCERY SHALL BE UNAVAILABLE, ANY DELAWARE STATE COURT AND THE FEDERAL COURT OF THE UNITED STATES OF AMERICA SITTING IN THE STATE OF DELAWARE) WILL HAVE EXCLUSIVE JURISDICTION OVER ANY AND ALL DISPUTES BETWEEN THE PARTIES HERETO, WHETHER IN LAW OR EQUITY, BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE AGREEMENTS, INSTRUMENTS AND DOCUMENTS CONTEMPLATED HEREBY OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION, WHETHER IN CONTRACT, TORT OR OTHERWISE. EACH OF THE PARTIES IRREVOCABLY CONSENTS TO AND AGREES TO SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH DISPUTE, IRREVOCABLY CONSENTS TO THE SERVICE OF THE SUMMONS AND COMPLAINT AND ANY OTHER PROCESS IN ANY OTHER ACTION OR PROCEEDING RELATING TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, ON BEHALF OF ITSELF OR ITS PROPERTY, BY DELIVERY IN ANY METHOD CONTEMPLATED BY SECTION 6.4 OR IN ANY OTHER MANNER AUTHORIZED BY LAW, AND HEREBY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUCH DISPUTE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY CLAIM THAT (i) SUCH PARTY IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF SUCH COURTS, (ii) SUCH PARTY AND SUCH PARTY’S PROPERTY IS IMMUNE FROM ANY LEGAL PROCESS ISSUED BY SUCH COURTS OR (iii) ANY LITIGATION COMMENCED IN SUCH COURTS IS BROUGHT IN AN INCONVENIENT FORUM.

(b)    THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT THAT ANY PARTY MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY PROCEEDING, LITIGATION OR COUNTERCLAIM BASED ON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY.

Section 6.9    Amendment; Waiver. This Agreement may not be amended or modified, except by an instrument in writing signed on behalf of each of the parties hereto; provided, further, that no provision of this Agreement may be amended or waived without the prior consent of the Conflicts Committee (which consent, subject to the Conflicts Committee’s duties under applicable Law and the Partnership Agreement, shall not be unreasonably withheld, delayed or conditioned). Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to the party benefiting from such waiver.

Section 6.10    Amendment and/or Waiver of Merger Agreement. The parties hereto agree that neither the Parent Parties nor the Partnership Parties will agree to (i) amend or modify the Merger Agreement in any way that materially adversely affects the Unitholder unless the Unitholder consents in writing to such amendment or modification, or (ii) waive any right of such party under the Merger Agreement in any way that materially adversely affects the Unitholder unless the Unitholder consents in writing to such waiver. For the avoidance of doubt, the parties agree that without limiting the prior sentence, any amendment or modification of, or the waiver of rights under, Sections 2.1(a), 2.1(b), 5.1(b)(but only if such amendment or modification further

10

restricts the conduct of the Partnership or its Subsidiaries business), 5.8, 5.11, 5.14, 5.18, 6.1, 6.2, 7.1, 7.2, 7.3, 8.13 or 8.14 of the Merger Agreement shall be deemed to materially adversely affect the Unitholder.

Section 6.11    Remedies. The parties hereto agree that money damages would not be a sufficient remedy for any breach of this Agreement and that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is hereby agreed that, prior to the valid termination of this Agreement pursuant to Section 6.1, the parties hereto shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach, to prevent breaches of this Agreement, and to specifically enforce compliance with this Agreement. In connection with any request for specific performance or equitable relief, each of the parties hereto hereby waives any requirement for the security or posting of any bond in connection with such remedy. Such remedy shall not be deemed to be the exclusive remedy for breach of this Agreement but shall be in addition to all other remedies available at law or equity to such party. The parties further agree that, by seeking the remedies provided for in this Section 6.11, no party hereto shall in any respect waive its right to seek any other form of relief that may be available to it (i) under this Agreement, including monetary damages in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 6.11 are not available or otherwise are not granted, or (ii) under the Merger Agreement.

Section 6.12    Unitholder Capacity. Notwithstanding anything contained in this Agreement to the contrary, the representations, warranties, covenants and agreements made herein by the Unitholder are made solely with respect to such Unitholder and the Covered Units and the GP LLC Interests. The Unitholder is entering into this Agreement solely in its capacity as the owner, directly or indirectly, of such Covered Units and GP LLC Interests and nothing herein shall (a) limit or affect any actions or omissions by the Unitholder in any other capacity, (b) be construed to prohibit, limit or restrict any actions or omissions by any affiliate or direct or indirect owner of the Unitholder, or any of its or their respective officers, directors, managers, representatives or employees, in each case, not acting as such on behalf of the Unitholder, including exercising rights under the Merger Agreement or (c) be construed to prohibit, limit or restrict any of the Unitholder’s direct or indirect owners or affiliates, or any of its or their respective officers, directors, managers, representatives or employees, from exercising its fiduciary duties, if any, to the limited partners of the Partnership under applicable Law.

Section 6.13    Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, trustee, beneficiary, settlor, agent, attorney, representative or affiliate of the Unitholder shall have any liability (whether in contract or in tort) for any obligations or liabilities of the Unitholder arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby; provided that notwithstanding the foregoing the Unitholder shall remain responsible for all obligations or liabilities of the Unitholder arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.

Section 6.14    Severability. To the fullest extent permitted by law, any term or provision of this Agreement, or the application thereof, that is invalid or unenforceable in any situation in

11

any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is illegal, void, invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any illegal, void, invalid or unenforceable term or provision with a term or provision that is legal, valid and enforceable and that comes closest to expressing the intention of the illegal, void, invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. To the fullest extent permitted by law, in the event such court does not exercise the power granted to it in the prior sentence, the parties hereto shall replace such illegal, void, invalid or unenforceable term or provision with a legal, valid and enforceable term or provision that will achieve, to the extent possible, the original economic, business and other purposes of such illegal, void, invalid or unenforceable term as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.15    Expenses. Except as otherwise expressly provided herein or in the Merger Agreement, all costs and expenses incurred in connection with this Agreement and the actions contemplated hereby shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

Section 6.16    Successors and Assigns; Third Party Beneficiaries.

(a)    Except in connection with a Permitted Transfer, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto; provided, however, that Parent, Merger Sub and GP Merger Sub may transfer or assign their rights and obligations under this Agreement, in whole or in part or from time to time in part, to one or more of their affiliates to which their rights are assigned pursuant to the terms of the Merger Agreement at any time. Any assignment in violation of the foregoing shall be null and void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b)    This Agreement is not intended to and shall not confer upon any person (other than the parties hereto) any rights or remedies hereunder.
