Prior to the mailing of the Proxy Statement/Prospectus, Buyer shall appoint American Stock Transfer and Trust Company, LLC or a commercial bank or trust company reasonably acceptable to MLP to act as exchange agent hereunder for the purpose of exchanging Certificates for the Applicable Merger Consideration (the “Exchange Agent”). At or before the Effective Time, Buyer shall deposit with the Exchange Agent for the benefit of the Holders of MLP Units for exchange in accordance with this Article III, through the Exchange Agent, certificates representing New Buyer Common Units and an amount of cash sufficient to effect the delivery of the Cash Consideration less the CW Holdings Cash Payment Amount. Before the Effective Time, CW Holdings shall deposit with the Exchange Agent for the benefit of the Holders of MLP Units (other than the CW Holders) for exchange in accordance with this Article III,

through the Exchange Agent, the CW Holdings Cash Payment Amount. Buyer agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 3.2 and Section 3.4(c) and to make Fractional Unit Payments pursuant to Section 3.4(e), in each case without interest. Any cash and certificates representing New Buyer Common Units deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Applicable Merger Consideration contemplated to be paid for the MLP Units pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 3.4(c) and Section 3.4(e), the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time (but in no event later than five Business Days after the Effective Time), Buyer shall cause the Exchange Agent to mail to each record holder of MLP Units as of the Effective Time a letter of transmittal (the “Letter of Transmittal”) (which shall specify that in respect of certificated MLP Units, delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and which shall have such other provisions as may be necessary for the Holders of MLP Units to be admitted as Additional Limited Partners in Buyer and which shall be in such form and have such other provisions as Buyer General Partner and MLP General Partner may reasonably specify) and instructions for use in effecting the surrender of the Certificates in exchange for the Applicable Merger Consideration payable in respect therefor. Promptly after the Effective Time, upon surrender of Certificates, if any, for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, each holder who held MLP Units immediately prior to the Effective Time shall be entitled to receive upon surrender of the Certificates therefor (i) certificates for New Buyer Common Units representing, in the aggregate, the whole number of New Buyer Common Units that such holder has the right to receive pursuant to this Article III (after taking into account all MLP Units then held by such holder) and (ii) a check in an amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to this Article III, including the Cash Consideration, any Fractional Unit Payments pursuant to Section 3.4(e) and distributions pursuant to Section 3.4(c). No interest shall be paid or accrued on any Applicable Merger Consideration or any distributions payable pursuant to Section 3.4(c). In the event of a transfer of ownership of MLP Common Units that is not registered in the transfer records of MLP, the Applicable Merger Consideration payable in respect of such MLP Common Units may be paid to a transferee, if the Certificate representing such MLP Common Units is presented to the Exchange Agent, and in the case of both certificated and book-entry MLP Common Units, accompanied by all documents reasonably required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Applicable Merger Consideration in any name other than that of the record holder of such MLP Common Units, or shall establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until such required documentation has been delivered and Certificates, if any, have been surrendered, as contemplated by this Section 3.4(b), each Certificate shall be deemed at any time after the Effective Time to

represent only the right to receive upon such delivery and surrender the Applicable Merger Consideration payable in respect of MLP Units, distributions pursuant to Section 3.4(c), and (without the necessity of such surrender) any cash or distributions to which such holder is entitled pursuant to Section 3.2.

(c) Distributions with Respect to Unexchanged Certificates. No dividends or other distributions declared with respect to Buyer Common Units with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to New Buyer Common Units that such holder would be entitled to receive in accordance herewith and no Fractional Unit Payment shall be paid to any such holder until such holder shall have delivered the required documentation and surrendered any such Certificate in accordance with this Article III. Subject to applicable Law, following compliance with the requirements of Section 3.4(b), there shall be paid to each such holder of New Buyer Common Units, without interest, (i) promptly after such compliance, the amount of any Fractional Unit Payment to which such holder is entitled pursuant to Section 3.4(e) and the amount of dividends or other distributions previously paid with respect to the New Buyer Common Units issuable with respect to such Certificate that have a record date after the Effective Time and a payment date on or prior to the time of surrender and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to such New Buyer Common Units with a record date after the Effective Time and prior to such surrender and a payment date subsequent to such surrender.

(d) No Further Ownership Rights in MLP Common Units or MLP Class D Units. The Applicable Merger Consideration paid upon conversion of an MLP Common Unit or Class D Unit in accordance with the terms hereof and any declared distributions to be paid on MLP Common Units or MLP Class D Units as described in Section 3.2(c) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to such MLP Units.

(e) Fractional Units. No certificates or scrip representing fractional New Buyer Common Units or book-entry credit of the same shall be issued upon the surrender of MLP Common Units or MLP Class D Units outstanding immediately prior to the Effective Time, and such fractional units shall not entitle the owner thereof to vote or to any rights as a unitholder of Buyer. Notwithstanding any other provision of this Agreement, each registered holder of MLP Units converted in the Merger who would otherwise have been entitled to receive a fractional New Buyer Common Unit (after taking into account all MLP Units exchanged by such holder) shall receive, in lieu thereof, from Buyer in exchange for such fractional unit, an amount (a “Fractional Unit Payment”) in cash (without interest rounded up to the nearest whole cent) equal to the product of (i) such fraction, multiplied by (ii) the average of the closing price of Buyer Common Units on the NYSE Composite Transaction Reporting System as reported in The Wall Street Journal (but subject to correction for typographical or other manifest errors in such reporting) over the five-day trading period ending on the third trading day immediately preceding the Effective Time. For the avoidance of doubt, all references to the “Applicable Merger Consideration” shall be deemed to include Fractional Unit Payments (if any), unless the context suggests otherwise.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Holders of the Certificates for twelve months after the Closing Date shall be delivered to Buyer, upon demand by Buyer, and any Holders of the Certificates who have not theretofore complied with this Article III shall thereafter look only to Buyer and only as general creditors thereof for payment of their claim for New Buyer Common Units, any Fractional Unit Payment and any distributions with respect to New Buyer Common Units to which such Holders may be entitled. If any Certificates shall not have been surrendered prior to such date on which any New Buyer Common Units, any Fractional Unit Payment or any distributions with respect to New Buyer Common Units in respect of such Certificate would escheat to or become the property of any Governmental Entity, any such units, cash, dividends or distributions in respect of such Certificates shall, to the extent permitted by applicable Law, become the property of Buyer, free and clear of all claims or interest of any Person previously entitled thereto.

(g) No Liability. To the fullest extent permitted by Law, none of Buyer, Buyer General Partner, MLP, MLP General Partner, the Surviving Entity or their respective Representatives shall be liable to any Person in respect of any New Buyer Common Units (or distributions with respect thereto) or Fractional Unit Payment properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(h) Withholding. Each of Buyer, the Surviving Entity and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of MLP Units such amounts or securities as Buyer, the Surviving Entity or the Exchange Agent is required to deduct and withhold under the Code or any provision of state, local or foreign Tax law, with respect to the making of such payment or issuance. To the extent that amounts or securities are so withheld by Buyer, the Surviving Entity or the Exchange Agent, such withheld amounts or securities shall be treated for all purposes of this Agreement as having been paid or issued to the holder of MLP Units in respect of whom such deduction and withholding was made by Buyer, the Surviving Entity or the Exchange Agent, as the case may be.

(i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Buyer, the posting by such Person of an indemnity agreement or a bond, in a customary amount, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Applicable Merger Consideration payable in respect of the MLP Units represented by such Certificate and any distributions to which the Holders thereof are entitled pursuant to Section 3.4(b) or (c).

(j) Book Entry and Admission of Holders of New Buyer Common Units as Additional Limited Partners of Buyer. All New Buyer Common Units to be issued in the Merger shall be issued in book-entry form, without physical certificates. Upon the issuance of New Buyer Common Units to the Holders of MLP Units in accordance with this Section 3.4, Buyer and Buyer General Partner shall be deemed to have automatically

consented to the admission of such holder as a limited partner of Buyer in respect of its New Buyer Common Units and shall reflect such admission on the books and records of Buyer.

(k) Investment of the Exchange Fund. Buyer shall cause the Exchange Agent to invest any cash included in the Exchange Fund as directed by Buyer on a daily basis, in Buyer’s sole discretion; provided, however, that (i) any investment of such Exchange Fund shall be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and (ii) no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to MLP unitholders pursuant to the other provisions of this Section 3.4. Any interest and other income resulting from such investments shall be paid promptly to Buyer.

SECTION 3.5 Treatment of Awards under MLP Unit Plan.

(a) MLP Restricted Common Units. All restrictions on each MLP Common Unit that is a restricted unit issued pursuant to the MLP Unit Plan (an “MLP Restricted Common Unit”) outstanding immediately prior to the Effective Time shall, immediately prior to the Effective Time, lapse. Each such MLP Restricted Common Unit outstanding as of the Effective Time (other than any MLP Restricted Common Units surrendered in connection with the payment of Taxes, if any, due upon the lapse of restrictions described in this Section 3.5(a), as permitted by and in accordance with the terms and conditions of the MLP Unit Plan) shall be considered an outstanding MLP Common Unit for all purposes of this Agreement, including with respect to the right to receive the Merger Consideration in accordance with this Article III.

(b) MLP Phantom Units. Each MLP Phantom Unit that is outstanding immediately prior to the Effective Time shall, immediately prior to the Effective Time, automatically and without any action on the part of the holder thereof, vest in full and the restrictions with respect thereto shall lapse. Each such MLP Common Unit that shall be issued in settlement of such MLP Phantom Unit (other than any MLP Common Units withheld in connection with the payment of Taxes, if any, due with respect to such MLP Phantom Units, as permitted by and in accordance with the terms and conditions of the MLP Unit Plan) shall be considered outstanding as of the Effective Time for all purposes of this Agreement, including with respect to the right to receive the Merger Consideration in accordance with this Article III. Each MLP Phantom Unit that is payable solely in cash and that vests pursuant to this Section 3.5(b) shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, vest in full and shall become immediately payable in cash.

(b) Section 4.1(b) of the MLP Disclosure Schedule sets forth, as of the Execution Date, a true and complete list of the MLP Group Entities, together with (i) the legal nature of each such Person, (ii) the jurisdiction of organization or formation of such Person, (iii) the name of the MLP Group Entity that owns directly or of record any equity or similar interest in such Person and (iv) the interest (expressed in a percentage or other amount) owned by such MLP Group Entity in such Person. Each of the MLP Group Entities is duly qualified and in good standing to do business as a foreign limited partnership, limited liability company, corporation or otherwise, as the case may be, in each jurisdiction in which the conduct or nature of its business or the ownership, leasing, holding or operating of its properties makes such qualification necessary, except such jurisdictions where the failure to be so qualified or in good standing, individually or in the aggregate, does not constitute an MLP Material Adverse Effect.

(c) Each of the MLP Parties has heretofore made available to Buyer complete and correct copies of its Governing Documents, in each case as amended to the Execution Date, and such Governing Documents are in full force and effect.

SECTION 4.2 Authority; No Violation; Consents and Approvals.

(a) Each of the MLP Parties has all requisite limited liability company or partnership power and authority, as applicable, to enter into this Agreement and to carry out its obligations hereunder and, subject to, with respect to consummation of the Merger, MLP Unitholder Approval, to consummate the transactions contemplated hereby. The execution, delivery and performance by each MLP Party of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all requisite limited liability company or partnership, as applicable, action on the part of such MLP Party. Subject to MLP Unitholder Approval, no other limited liability company or partnership proceedings are necessary to consummate the transactions contemplated by

this Agreement (except for the filing of the appropriate merger documents as required by Delaware law). This Agreement has been duly executed and delivered by each MLP Party and, assuming the due authorization, execution and delivery hereof by the Other Parties, constitutes a legal, valid and binding agreement of each MLP Party, enforceable against such MLP Party in accordance with its terms (except insofar as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a Proceeding in equity or at law)). The adoption of this Agreement by the affirmative vote or consent of the Holders of at least a “Unit Majority” (as such term is defined in the MLP Partnership Agreement) (the “MLP Unitholder Approval”) is the only additional vote of partnership interests in MLP necessary to approve this Agreement and the Merger.

(b) Assuming the consents, approvals and filings referred to in Section 4.2(b) of the MLP Disclosure Schedule and the MLP Unitholder Approval are obtained or made, neither the execution and delivery by the MLP Parties of this Agreement, nor the consummation by the MLP Parties of the transactions contemplated hereby, nor compliance by the MLP Parties with any of the terms or provisions of this Agreement, will (i) violate any provision of the Governing Documents of any of the MLP Group Entities; (ii) result in any breach of or constitute a default (or an event that, with notice or lapse of time or both, would become a default) under, or give to others any right of termination, cancellation, amendment or acceleration of any obligation or the loss of any benefit under any agreement, permit, franchise, note, indenture, bond, mortgage, lease or instrument to which any of the MLP Group Entities is a party or by or to which any of their properties are bound; (iii) result in the creation of an Encumbrance, other than Permitted Encumbrances, upon or require the sale or give any Person the right to acquire any of the assets of any of the MLP Group Entities, or restrict, hinder, impair or limit the ability of any of the MLP Group Entities to carry on its business as and where it is now being carried on; or (iv) violate any Law applicable to the MLP Group Entities, except for matters described in clauses (ii), (iii) or (iv) that do not, individually or in the aggregate, constitute an MLP Material Adverse Effect.

(c) No consent, approval, order or authorization of, or registration, declaration or filing with, or permit from, any Governmental Entity, is required to be obtained or made by any MLP Group Entity in connection with the execution and delivery of this Agreement by the MLP Parties or the consummation by the MLP Parties of the transactions contemplated by this Agreement, except for: (i) the filing with the SEC of (A) a proxy statement in preliminary and definitive form relating to the meeting of the unitholders of MLP to be held in connection with adoption of this Agreement and (B) such reports under Section 13(a) of the Exchange Act, and such other compliance with the Exchange Act and the rules and regulations thereunder, as may be required in connection with this Agreement and the transactions contemplated by this Agreement; (ii) the filing of the certificate of merger with the Office of the Secretary of State of the State of Delaware; (iii) any filings, consents, authorizations, approvals or exemptions in connection with compliance with the rules of the NYSE; (iv) such filings, consents, authorizations, approvals or exemptions as may be required by any applicable state

securities or “blue sky” or takeover laws; and (v) any such consent, approval, order, authorization, registration, filing, or permit that the failure to obtain or make do not constitute, individually or in the aggregate, an MLP Material Adverse Effect.

SECTION 4.5 Absence of Undisclosed Liabilities.

(a) Neither MLP nor any of the MLP Subsidiaries has any indebtedness or liability, absolute or contingent, which is of a nature required to be reflected on the balance sheet of MLP or in the notes thereto, in each case prepared in conformity with GAAP, and which is not shown or reserved against on the MLP Financial Statements, other than

(i) liabilities incurred or accrued in the ordinary course of business consistent with past practice since December 31, 2012, including liens for current Taxes and assessments not in default;

SECTION 4.6 MLP SEC Reports and Internal Controls.

(a) Since December 31, 2010, all reports (except for the Proxy Statement/Prospectus, which is addressed in Section 4.7), including but not limited to the Annual Reports on Form 10-K, the Quarterly Reports on Form 10-Q and the Current Reports on Form 8-K, forms, schedules, statements and other documents required to be filed or furnished by MLP with or to the SEC, as applicable, pursuant to the Exchange Act or the Securities Act (the “MLP SEC Reports”), have been timely filed or furnished in accordance with the rules and regulations of the SEC. All such MLP SEC Reports (i) complied as to form in all material respects in accordance with the requirements of the Exchange Act and the Securities Act, as the case may be, and the rules and regulations thereunder and (ii) as of its filing date in the case of any Exchange Act report and as of its effective date in the case of any Securities Act filing, 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 the light of the circumstances under which they were made, not misleading. As of the Execution Date, there are no outstanding or unresolved comments received from the SEC staff with respect to the MLP SEC Reports. To the Knowledge of the MLP, none of the MLP SEC Reports is the subject of ongoing SEC review or investigation.

(b) MLP has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act. MLP’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by MLP in the reports that it files under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to MLP’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations promulgated thereunder (the “Xxxxxxxx-Xxxxx Act”). MLP’s management has completed its assessment of the effectiveness of MLP’s internal control over financial reporting in compliance with the requirements of Section 404 of the Xxxxxxxx-Xxxxx Act for the year ended December 31, 2012, and such assessment concluded that such controls were effective. To MLP’s Knowledge, it has disclosed, based on its most recent evaluations, to MLP’s outside auditors and the audit committee of the MLP Board (i) all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect MLP’s ability to record, process, summarize and report financial information (as defined in Rule 13a-15(f) of the Exchange Act) and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the MLP’s internal controls over financial reporting.

No MLP Group Entity has received any written communication within the past two years from a Governmental Entity that alleges that any MLP Group Entity is not in compliance with or is in default or violation of any applicable Law, except where such non-compliance, default or violation would not constitute, individually or in the aggregate, an MLP Material Adverse Effect.

None of the MLP Group Entities is in default or violation of any of the MLP Permits, except for any such defaults or violations that would not, individually or in the aggregate, constitute an MLP Material Adverse Effect. No suspension or cancellation of any of the MLP Permits is pending or, to the Knowledge of MLP, threatened, except where such suspension or cancellation would not constitute, individually or in the aggregate, an MLP Material Adverse Effect. As of the Execution Date, to the Knowledge of MLP, no event or condition has occurred or exists which would result in a violation of, breach, default or loss of a benefit under, or acceleration of an obligation of the MLP Group Entities under, any MLP Permit, or has caused (or would cause) an applicable Governmental Entity to fail or refuse to issue, renew or extend any MLP Permit (in each case, with or without notice or lapse of time or both), except for violations, breaches, defaults, losses, accelerations or failures that would not constitute, individually or in the aggregate, an MLP Material Adverse Effect.

SECTION 4.10 Legal Proceedings. There are no pending (or, to the Knowledge of the MLP Parties, threatened) Proceedings, with respect to which any MLP Group Entity has been contacted in writing by counsel for the plaintiff or claimant, against or affecting any MLP Group Entity or any of their properties, assets, operations or business and which constitute, individually or in the aggregate, an MLP Material Adverse Effect.

SECTION 4.11 Environmental Matters. Except as reflected in the MLP Financial Statements, and except for any such matter that individually or in the aggregate would not constitute an MLP Material Adverse Effect:

(a) The MLP Parties shall, in accordance with applicable Law and the MLP Partnership Agreement, cause a meeting of the Holders of MLP Units (the “MLP Unitholders’ Meeting”) to be duly called and held, as soon as practicable after the Registration Statement is declared effective under the Securities Act (and in any event no later than 45 days thereafter), for the purpose of obtaining the MLP Unitholder Approval. Unless there has been an MLP Recommendation Change, (i) the MLP Parties shall use their reasonable best efforts to solicit and obtain the MLP Unitholder Approval; and (ii) the MLP Parties shall include in the Proxy Statement/Prospectus the recommendation by the MLP Board of the adoption of this Agreement by the Holders of MLP Units (the “MLP Recommendation”). The MLP Parties shall be required to cause the MLP Unitholders’ Meeting be called and held even if the MLP Board (or the MLP Conflicts Committee) effected an MLP Recommendation Change.

(b) The MLP Parties shall not adjourn or postpone the MLP Unitholders’ Meeting except to the extent the MLP Board or the MLP Conflicts Committee determines in good faith, after consultation with outside counsel, that such adjournment or postponement is required by applicable securities Law; provided, however, that the MLP Parties (or the MLP Conflicts Committee), after consultation with Buyer, may adjourn or postpone the MLP Unitholders’ Meeting (i) to the extent the MLP Board or the MLP Conflicts Committee believes in good faith, after consultation with outside legal counsel, that such adjournment or postponement is necessary to ensure that any required supplement or amendment to the Proxy Statement/Prospectus or other required public disclosure is provided to Holders of MLP Units and that such Holders of MLP Units have a reasonable period of time to review any such supplement or amendment; (ii) if as of the time for which the MLP Unitholders’ Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus) there are insufficient MLP Units represented (either in Person or by proxy) to constitute a quorum necessary to conduct business at such meeting; or (iii) to solicit additional proxies for the purpose of obtaining the MLP Unitholder Approval; provided, further, that unless otherwise agreed to by the Parties, the MLP Unitholders’ Meeting may not be adjourned or postponed to a date that is more than 20 Business Days after the date for which the meeting was originally scheduled (excluding any adjournments or postponements required by applicable securities Law); provided further, that, notwithstanding the foregoing, the MLP Parties may postpone or adjourn such meeting until the fifth Business Day after the expiration of any Recommendation Change Notice Period or Superior Proposal Notice Period.

SECTION 6.5 Non-Solicitation; Change in Recommendation.

(a) The MLP Parties shall, and shall cause their respective Subsidiaries and shall use their reasonable best efforts to cause their respective Representatives to, immediately cease and terminate any solicitation, discussions or negotiations with any Person that may be ongoing with respect to or that may reasonably be expected to lead to an MLP Takeover Proposal.

(b) The MLP Parties shall not, and shall cause their respective Subsidiaries and shall use their reasonable best efforts to cause their respective Representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate (including by way of furnishing information) any inquiries regarding, or the making or submission of any proposal or offer that constitutes an MLP Takeover Proposal (provided that the nothing in this Agreement shall prohibit any of the MLP Parties or their Representatives from informing any Person of the provisions of this Section 6.5 or from contacting any Person or group of Persons who has made an MLP Takeover Proposal after Execution Date solely to request the clarification of terms and condition thereof to determine whether the MLP Takeover Proposal is, or could reasonably be expected to lead to, a Superior Proposal); (ii) conduct or participate in any discussions or negotiations regarding any MLP Takeover Proposal; (iii) furnish to any Person any non-public information or data relating to MLP or any of its Subsidiaries or afford access to the business, properties, assets, or, except as required by Law or the MLP Partnership Agreement, books or records of MLP or any of its Subsidiaries in any such case in connection with an MLP Takeover Proposal; or (iv) approve or recommend, or propose to approve or recommend, or allow any MLP Group Entity to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to, or that is intended to lead to any MLP Takeover Proposal (other than a confidentiality agreement permitted to be entered into by, and in accordance with, the next sentence). Notwithstanding the foregoing, at any time prior to obtaining the MLP Unitholder Approval, the MLP Parties and their Subsidiaries and Representatives may take the actions described in clauses (ii) and (iii) of this Section 6.5(b) with respect to a third Person that makes a bona fide unsolicited written MLP Takeover Proposal that did not result from a material breach of this Section 6.5(b) (a “Receiving Party”), if (A) the MLP Board (or the MLP Conflicts Committee) determines in good faith (after consultation with outside legal counsel) that such MLP Takeover Proposal is, or could reasonably be expected to lead to, an MLP Superior Proposal; (B) the MLP Board (or the MLP Conflicts Committee), after consultation with its outside legal counsel and financial advisors, determines in good faith that the failure to take such action would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law; and (C) prior to furnishing any such non-public information to such Receiving Party, MLP receives from such Receiving Party an executed confidentiality agreement on terms substantially similar to, and not materially less favorable to the MLP Parties in the aggregate than, those contained in the Confidentiality Agreement (including the standstill obligations contained in Section 13 and the non-solicitation obligations contained in Section 14 of the Confidentiality Agreement). The MLP Parties shall as promptly as practicable (in all events within 24 hours) provide to Buyer a copy of such confidentiality agreement. The MLP Parties shall, as promptly as practicable (and in any event within 24 hours), advise Buyer in writing of any request for non-public information in connection with an MLP Takeover Proposal, any MLP Takeover Proposal received from any third person, or any request for discussions or negotiations with respect to any MLP Takeover Proposal, and, in the case of any MLP Takeover Proposal received, the material terms and conditions of such MLP Takeover Proposal. The MLP Parties shall, as promptly as practicable (and in all events

within 24 hours), provide to Buyer complete copies of any written proposal or offers (including proposed agreements) received by the MLP Parties or any of their Subsidiaries or Representatives in connection with any of the foregoing, and the identity of the Person making any such request or MLP Takeover Proposal.

(c) The MLP Board and the MLP Conflicts Committee shall not, in each case unless permitted by Section 6.5(d), (i) fail to include the MLP Recommendation in the Proxy Statement/Prospectus; (ii) withdraw, or modify in any manner adverse to the Buyer Parties, or propose publicly to withdraw, or modify in any manner adverse to the Buyer Parties), the MLP Recommendation; or (iii) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any MLP Takeover Proposal (any action described in this Section 6.5(c) being referred to as an “MLP Recommendation Change”); provided, however, that nothing in this Agreement shall prohibit accurate disclosure (and such disclosure shall not be deemed to be an MLP Recommendation Change) of factual information regarding the business, financial condition or results of operations of the MLP Parties or the Buyer Parties or the fact that an MLP Takeover Proposal has been made, the identity of the Person making such proposal or the material terms of such proposal in the Proxy Statement/Prospectus or otherwise, in each case to the extent the MLP Parties in good faith determine, after consultation with its outside legal counsel, that such information, facts, identity or terms is required to be disclosed under applicable Law.

(d) Notwithstanding any other provision of this Agreement, at any time prior to obtaining the MLP Unitholder Approval, the MLP Board (and/or the MLP Conflicts Committee) may effect an MLP Recommendation Change if the MLP Board (or the MLP Conflicts Committee), after consultation with its outside legal counsel and financial advisors, determines in good faith that the failure to take such action would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law and:

(i) if the MLP Board (or the MLP Conflicts Committee) intends to effect such MLP Recommendation Change in response to an MLP Takeover Proposal:

(A) such MLP Takeover Proposal is bona fide, in writing and has not been withdrawn or abandoned;

(B) the MLP Board (or MLP Conflicts Committee) has determined, after consultation with its outside legal counsel and financial advisors, that such MLP Takeover Proposal constitutes an MLP Superior Proposal after giving effect to all of the adjustments offered by the Buyer Parties pursuant to clause (E) below;

(C) the MLP Parties have provided prior written notice to the Buyer Parties in accordance with Section 9.3 (the “Superior Proposal Notice”) of the MLP Board’s (or the MLP Conflicts Committee’s) intention to effect an MLP Recommendation Change, and such Superior Proposal Notice has specified the identity of the Person making such MLP Takeover Proposal, the material terms and conditions of such MLP Takeover Proposal, and complete copies of any written proposal or offers (including proposed agreements) received by the MLP Parties in connection with such MLP Takeover Proposal;

(D) during the period that commences on the date of delivery of the Superior Proposal Notice as determined in accordance with Section 9.3 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “Superior Proposal Notice Period”), the MLP Parties shall, and shall cause their Representatives to, (1) negotiate with the Buyer Parties and its Representatives in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the MLP Board (or the MLP Conflicts Committee) not to effect an MLP Recommendation Change; and (2) keep the Buyer Parties and its Representatives reasonably informed with respect to the status and changes in the material terms and conditions of such MLP Takeover Proposal or other change in circumstances related thereto; provided, however, any material revisions to such MLP Takeover Proposal (it being agreed that any change in the purchase price in such MLP Takeover Proposal shall be deemed a material revision) shall require delivery of a subsequent Superior Proposal Notice and a subsequent Superior Proposal Notice Period in respect of such revised MLP Takeover Proposal, except that such subsequent Superior Proposal Notice Period shall expire upon the later of (x) the end of the initial Superior Proposal Notice Period and (y) 11:59 p.m. Central time on the date that is the third calendar day following the date of the delivery of such subsequent Superior Proposal Notice; and

(E) the MLP Board (or the MLP Conflicts Committee) shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by the Buyer Parties and, at the end of the Superior Proposal Notice Period, shall have determined in good faith that such MLP Takeover Proposal continues to constitute a Superior Proposal even if such revisions were to be given effect; or

(ii) if the MLP Board (or the MLP Conflicts Committee) intends to effect such MLP Recommendation Change due to circumstances not involving an MLP Takeover Proposal:

(A) the MLP Parties have provided prior written notice to the Buyer Parties in accordance with Section 9.3 (the “Recommendation Change Notice”) of the MLP Board’s (or the MLP Conflicts Committee’s) intention to effect an MLP Recommendation Change, and such Recommendation Change Notice has specified the reasons for the MLP Recommendation Change;

(B) during the period that commences on the date of delivery of the Recommendation Change Notice as determined in accordance with Section 9.3 and ends at 11:59 p.m. Central time the date that is the fifth calendar day following the date of such delivery (the “Recommendation Change Notice Period”), the MLP Parties shall, and shall cause their Representatives to, (A) negotiate with the Buyer Parties and its Representatives in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the MLP Board (or the MLP Parties) not to effect an MLP Recommendation Change; and (B) keep the Buyer Parties and its Representatives reasonably informed of any change in circumstances related thereto; and

(C) the MLP Board (or the MLP Conflicts Committee) shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by the Buyer Party and, at the end of the Recommendation Change Notice Period, shall have determined in good faith that the failure to effect an MLP Recommendation Change would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law even if such revisions were to be given effect.

(e) Nothing contained in this Agreement shall prevent the MLP Board (or the MLP Conflicts Committee) from taking and disclosing to the limited partners of MLP a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act (or any similar communication to Holders of MLP Units) or from making any legally required disclosure to the limited partners of MLP. Any “stop-look-and-listen” communication by the MLP Board (or the MLP Conflicts Committee) to the limited partners of MLP pursuant to Rule 14d-9(f) promulgated under the Exchange Act (or any similar communication to the Holders of MLP Units) shall not be considered an MLP Recommendation Change.

(f) The MLP Parties shall, and shall cause their respective Subsidiaries to, request all Persons (other than the Buyer Parties and their Representatives) who have been furnished confidential information regarding the MLP Parties or their Subsidiaries in connection with the solicitation of or discussions regarding an MLP Takeover Proposal within the 12 months prior to the Execution Date promptly to return or destroy such information to the extent that the MLP Parties or their respective Subsidiaries are entitled to have such documents returned or destroyed.

(g) Except to the extent the MLP Board (or the MLP Conflicts Committee) determines in good faith that the failure to take such action would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law, each of the MLP Parties agrees not to, and to cause its Subsidiaries not to, release any third Person from the confidentiality and standstill provisions of any agreement to which such MLP Party or its Subsidiaries is or may become a party.

(h) Each MLP Party shall use its reasonable best efforts to inform all Representatives of such MLP Party and its Subsidiaries of the restrictions described in this Section 6.5. Notwithstanding anything to the contrary in this Section 6.5, any action, or failure to take action, in violation of the restrictions set forth in this Section 6.5 by any Representative of an MLP Party or any of its Subsidiaries at the direction or with the consent of such MLP Party or any of its Subsidiaries shall be deemed to be a breach of this Section 6.5.

SECTION 6.6 Reasonable Best Efforts; Further Assurances. From and after the Execution Date, upon the terms and subject to the conditions hereof, each of the Parties shall use its reasonable best efforts to take, or cause to be taken, all appropriate action, and to do or cause to be done, all things necessary, proper or advisable under applicable Law and Environmental Law to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable. Without limiting the foregoing but subject to the other terms of this Agreement, the Parties agree that, from time to time, whether before, at or after the

Closing Date, each of them shall execute and deliver, or cause to be executed and delivered, such instruments of assignment, transfer, conveyance, endorsement, direction or authorization as may be necessary to consummate and make effective the transactions contemplated by this Agreement.

SECTION 6.7 No Public Announcement. On the Execution Date, the Parties shall issue a joint press release with respect to the execution of this Agreement and the Merger, which press release shall be reasonably satisfactory to Buyer General Partner and MLP General Partner. No Party shall issue any other press release or make any other public announcement concerning this Agreement or the transactions contemplated by this Agreement (other than an MLP Recommendation Change, as may be required by Law or by obligations pursuant to any listing agreement with the NYSE, in which event the Party making the public announcement or press release shall, to the extent practicable, (a) notify the Buyer General Partner or MLP General Partner, as applicable, in advance of such public announcement or press release; and (b) allow the Other Party reasonable time to comment on such public announcement in advance of such issuance) without the prior approval of the Buyer General Partner or MLP General Partner, as applicable, which approval shall not be unreasonably withheld, delayed or conditioned. Notwithstanding the foregoing, the Buyer Parties and the MLP Parties may respond to inquiries from securities analysts and the news media to the extent necessary to respond to such inquiries; provided, however, that such responses shall be in compliance with applicable securities Law.

SECTION 6.8 Expenses. Whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement, including legal fees, accounting fees, financial advisory fees and other professional and non-professional fees and expenses, shall be paid by the Party incurring such expenses.

SECTION 6.9 Tax Matters.

(a) The Parties intend to take the position that the Merger will constitute an “assets-over” partnership merger within the meaning of Treasury Regulations Section 1.708-1(c)(3)(i) and any cash deemed received by MLP will be treated as reimbursement of preformation expenditures in accordance with Treasury Regulations Section 1.707-4(d).

(b) The Buyer Parties and the MLP Parties acknowledge and agree that, for U.S. federal income tax purposes, the transactions contemplated by this Agreement shall cause a termination of MLP pursuant to Section 708(a)(1)(A) of the Code. As a result, for U.S. federal income tax purposes, the taxable year of MLP shall end as of the Closing Date and the Parties shall take all actions permitted under applicable Laws to close the Tax periods of the subsidiaries of MLP other than Crestwood Midstream Finance Corporation as of the Closing Date. Allocation of income or deductions relating to the period ending on the Closing Date shall be taken into account by means of an interim closing of the books; provided, however, that exemptions, allowances or deductions that are calculated for an entire Tax period (including, but not limited to, depreciation and amortization deductions) shall be allocated between the portion of such Tax period

ending on the Closing Date and the remaining portion of such period in proportion to the number of days in each such period. Buyer shall prepare and file, or cause to be prepared and filed, all Tax Returns of MLP and its subsidiaries required to be filed after the Closing Date; provided, however, that Buyer shall timely provide the MLP Representative with a copy of any Tax Return (together with all supporting documentation and workpapers) to be filed by or with respect to MLP or any of its subsidiaries for any Tax period that begins on or before the Closing Date at least thirty (30) days prior to the due date for filing such Tax Return for the MLP Representative’s review and reasonable comment. Buyer shall take into account any changes reasonably requested by the MLP Representatives and cause such Tax Return to be filed timely, providing a copy of the Tax Return as filed to the MLP Representatives.

(c) All sales, use, stamp, registration, value added, documentary, filing, recording, transfer or similar fees or Taxes or governmental charges levied by any Governmental Entity in connection with the transactions contemplated by this Agreement, shall be borne by Buyer. The Parties shall cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Taxes.

SECTION 6.10 Section 16(b). Prior to the Effective Time, MLP and Buyer shall take such actions as may be necessary to cause acquisitions or dispositions of equity securities of MLP and Buyer resulting from the transactions contemplated by this Agreement by each Person (including any Person who may be deemed to be a “director by deputization” under applicable securities laws) who may be subject to Section 16 of the Exchange Act with respect to MLP, or may become subject to such requirements with respect to Buyer, to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with the procedures set forth in such Rule 16b-3 and the Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP SEC No-Action Letter (January 12, 1999).

SECTION 6.11 Indemnification, Exculpation and Insurance.

(a) Without limiting any other rights that any Indemnified Person may have pursuant to any employment agreement or indemnification agreement or under the MLP Partnership Agreement, the Governing Documents of the MLP General Partner or this Agreement in effect on the Execution Date, from the Effective Time and until the six (6) year anniversary of the Effective Time, Buyer shall indemnify, defend and hold harmless each Person who is now, or has been at any time prior to the Execution Date or who becomes prior to the Effective Time, a director or officer of any of the MLP Group Entities or who acts as a fiduciary under any Employee Benefit Plan of the MLP Group Entities (the “Indemnified Persons”) against all losses, claims, damages, costs, fines, penalties, expenses (including reasonable attorneys’ and other professionals’ fees and expenses), liabilities or judgments or amounts that are paid in settlement (with the approval of the indemnifying party, which approval shall not be unreasonably withheld, delayed or conditioned), of or incurred in connection with any threatened or actual Proceeding to which such Indemnified Person is a party by reason of the fact that such Person is or was a director or officer of any of the MLP Group Entities, a fiduciary under any Employee Benefit Plan or is or was serving at the request of any of the MLP Group Entities as a director, officer, employee or agent of another corporation, partnership,

limited liability company, joint venture, trust or other enterprise existing prior to or at the Effective Time and whether asserted or claimed prior to, at or after the Effective Time (“Indemnified Liabilities”), including all Indemnified Liabilities based in whole or in part on, or arising in whole or in part out of, or pertaining to, this Agreement or the transactions contemplated hereby, in each case to the fullest extent permitted under applicable Law (and Buyer shall pay expenses incurred in connection therewith promptly as statements therefor are received to each Indemnified Person to the fullest extent permitted under applicable Law).

(b) Without limiting the foregoing, in the event any such Proceeding is brought or threatened to be brought against any Indemnified Persons (whether arising before or after the Effective Time): (i) the Indemnified Persons may retain MLP’s regularly engaged legal counsel or other counsel satisfactory to them, and Buyer shall pay all reasonable fees and expenses of such counsel for the Indemnified Persons promptly as statements therefor are received, and (ii) Buyer shall use its reasonable best efforts to assist in the defense of any such matter (and the Indemnified Persons shall cooperate with Buyer with respect thereto); provided, however, that Buyer shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned). Any Indemnified Person wishing to claim indemnification or advancement of expenses under this Section 6.11, upon learning of any such Proceeding, shall notify Buyer (but the failure so to notify shall not relieve a Party from any obligations that it may have under this Section 6.11 except to the extent such failure materially prejudices such Party’s position with respect to such claims); provided, further, that Buyer shall not be obligated pursuant to this Section 6.11(b) to pay the fees and disbursements of more than one (1) counsel for all Indemnified Persons in any single action, unless, in the good faith judgment of any of the Indemnified Persons, there is or may be a conflict of interest between two or more of such Indemnified Persons, in which case there may be separate counsel for each similarly situated group. With respect to any determination of whether any Indemnified Person is entitled to indemnification by Buyer under this Section 6.11, such Indemnified Person shall have the right to require that such determination be made by special, independent legal counsel jointly selected by the Indemnified Person and Buyer, and who has not otherwise performed material services for Buyer or the Indemnified Person within the last three (3) years.

(c) Buyer and the Surviving Entity shall not amend, repeal or otherwise modify (i) the certificate of limited partnership or MLP Partnership Agreement of the Surviving Entity or (ii) the certificate of limited partnership of Buyer or the Buyer Partnership Agreement, in each case, in any manner that would affect adversely the rights thereunder of any Indemnified Person to indemnification, exculpation and advancement except to the extent required by applicable Law. Buyer shall, and shall cause the Surviving Entity to, fulfill and honor any indemnification, expense advancement or exculpation agreements between the MLP Group Entities and any of their directors, officers or employees existing immediately prior to the Effective Time.

(d) Buyer and the Surviving Entity shall, to the fullest extent permitted by Law, indemnify any Indemnified Person against, and advance expenses to any

Indemnified Person with respect to, all reasonable costs and expenses (including reasonable attorneys’ fees and expenses) relating to the enforcement of such Indemnified Person’s rights under this Section 6.11 or under any Governing Documents or contract; provided that such indemnification shall be provided only if such Indemnified Person is ultimately determined to be entitled to indemnification hereunder or thereunder promptly following such determination.

(e) In the event that Buyer or the Surviving Entity or any of their respective successors or assigns: (i) consolidates with or merges into any other Person and is not the continuing or surviving entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its assets to any Person, then, and in each such case, Buyer and the Surviving Entity shall cause proper provision to be made so that the successors and assigns of Buyer or the Surviving Entity, as the case may be, assume the obligations set forth in this Section 6.11 contemporaneous with the closing of any such consolidation, merger, transfer or conveyance.

(f) At or prior to the Effective Time, MLP may cause to be put in place, or, if requested by MLP, the Buyer shall cause to be put in place, and, in either case, Buyer shall fully prepay immediately prior to the Effective Time, “tail” insurance policies covering claims for at least for six (6) years following the Effective Time from an insurance carrier with the same or better credit rating as MLP’s current insurance carrier with respect to directors’ and officers’ liability insurance in an amount and scope of not less than the existing coverage and having other terms at least as favorable to the insured Persons as the directors’ and officers’ liability insurance coverage maintained by the MLP Group Entities as of the Execution Date; provided, however, that in no event shall Buyer or the Surviving Entity be required to expend pursuant to this Section 6.11(f) more than an amount per year equal to 300% of current annual premiums paid by MLP for such insurance (the “Premium Cap”), in which case the Surviving Entity shall, and Buyer shall cause the Surviving Entity to, use reasonable best efforts to maintain in effect, at no expense to the beneficiaries, for a period of at least six (6) years from the Effective Time for the persons who are covered by MLP’s existing directors’ and officers’ liability insurance, with the best overall terms, conditions, retentions and levels of coverage reasonably available for an annual premium equal to the Premium Cap. Buyer shall maintain such policy in full force and effect and continue to honor the obligations thereunder.

SECTION 6.12 Distributions. The Buyer Parties and the MLP Parties shall coordinate with each other the declaration of, and the setting of record dates and payment dates for, distributions in respect of their respective units so that, in respect of any fiscal quarter, Holders of MLP Units do not (a) receive more than one distribution in respect of both (i) MLP Units and (ii) Buyer Common Units received pursuant to the Merger in exchange therefor; or (b) fail to receive a distribution in respect of one of (i) MLP Units or (ii) Buyer Common Units received pursuant to the Merger in exchange therefor.

SECTION 6.13 Limited Liability Company Interests of MLP General Partner. At or prior to the Effective Time, NRGY shall transfer 100% of its limited liability company interest in MLP General Partner to Buyer General Partner, which MLP General Partner will at the time of such transfer own 100% of the MLP Incentive Distribution Rights. At or prior to the Effective Time, Buyer shall cause New General Partner to be formed as a Subsidiary of Buyer.

SECTION 6.14 Amendment of the MLP Partnership Agreement. At the Effective Time, the MLP Partnership Agreement shall be amended and restated so that it reads substantially in the form of the MLP Amended and Restated Partnership Agreement.

SECTION 6.15 Buyer Board Directors. NRGY shall not change, or cause to be changed, any of the directors of the Buyer Board until the earlier of (a) the termination of the Option Agreement pursuant to its terms and (b) the Effective Time; provided, however, that NRGY may add, or cause to be added, additional directors to the Buyer Board if NRGY causes the Buyer Board to delegate to the Buyer Special Committee all its authority to negotiate and/or approve any amendments, supplements, waivers or modifications in respect of this Agreement and all other agreements contemplated hereby (including the Voting Agreement and the Option Agreement), or approve or agree to any termination of this Agreement or any other agreement contemplated hereby (including the Voting Agreement and the Option Agreement), and exercise all rights under this Agreement and any other agreement contemplated hereby (including the Voting Agreement and the Option Agreement).

SECTION 6.16 Financing.

(a) The Buyer Parties shall use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary to arrange the Debt Refinancing on the terms and conditions described in the Refinancing Commitment Letter, including using their commercially reasonable efforts to (i) maintain in effect the Refinancing Commitment Letter; (ii) satisfy on a timely basis all conditions applicable to the Buyer Parties to obtaining the Debt Refinancing as set forth in the Refinancing Commitment Letter that are within its control; (iii) negotiate and enter into definitive agreements with respect thereto on the terms and conditions (including, if necessary, the flex provisions) contemplated by the Refinancing Commitment Letter or on other terms no less favorable to Buyer; (iv) comply with the Buyer’s obligations under the Refinancing Commitment Letter and the definitive agreements with respect thereto; (v) subject to the terms and conditions contemplated in the Refinancing Commitment Letter, consummate the Debt Refinancing at or prior to the Effective Time; and (vi) enforce its rights under the Refinancing Commitment Letter. If any portion of the Debt Refinancing becomes unavailable on the terms and conditions (including the flex provisions) contemplated in the Refinancing Commitment Letter or the definitive agreements with respect thereto, the Buyer Parties shall promptly notify the MLP Parties and use their commercially reasonable efforts to amend, modify, supplement, alter, restate, substitute or replace the Debt Refinancing with other alternative financing, on terms no less favorable to Buyer, as promptly as possible; provided, however, that the Buyer Parties shall not permit any amendment, modification, supplement, alteration, restatement, substitution or replacement of the Refinancing Commitment Letter or the Debt Refinancing on terms that are less favorable to Buyer, without the prior consent of the MLP Parties, such consent not to be unreasonably withheld, delayed or conditioned. In such event, the term “Refinancing Commitment Letter” as used herein shall be deemed to include the amended, modified, supplemented, altered, restated, substituted or

replacement, commitment letter. The Buyer Parties shall promptly (and in any event within two Business Days) notify the MLP Parties: (A) of any default or breach by any party to the Refinancing Commitment Letter or definitive documents related to the Debt Refinancing of which the Buyer Parties are aware; (B) of the receipt of any written notice from any party to the Refinancing Commitment Letter with respect to (1) any default, breach, termination or repudiation by any party to the Refinancing Commitment Letter or definitive documents related to the Debt Refinancing or (2) any material dispute or disagreement between or among parties to the Refinancing Commitment Letter or definitive documents related to the Debt Refinancing of which the Buyer Parties become aware; and (C) if for any reason the Buyer Parties determine in good faith that they will not be able to obtain all or any portion of the Debt Refinancing on the terms, in the manner or from the sources contemplated by the Refinancing Commitment Letters. The Buyer Parties shall keep the MLP Parties informed on a reasonably current basis of the status of their efforts to arrange the Debt Refinancing and provide copies of all draft and executed documents related to the Debt Refinancing to the MLP Parties. In the event that the Buyer Parties are unable to obtain the Debt Refinancing or alternative financing on terms no less favorable to Buyer, the Buyer Parties will obtain an amendment to the Buyer Credit Agreement so that the Buyer will be permitted thereunder to, and will have sufficient funds available thereunder to, refinance the MLP Credit Agreements at the Closing; provided, however, that the Buyer Parties shall be permitted to pay any and all fees to the lenders and administrative agent in connection with any such amendment without the prior consent of the MLP Parties.

(b) The Buyer Parties shall use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary to maintain in effect the Repurchase Commitment Letter. If a “Ratings Decline” (as defined in the Buyer Indenture) has occurred within 90 days following the consummation of the General Partner Transactions (or the Parties reasonably expect such a Ratings Decline to occur) and there has not been a successful consent solicitation as described in Section 6.17(a), the Buyer Parties shall comply with all the terms of Section 4.15 of the Buyer Indenture and conduct a “Change of Control Offer” (as defined in the Buyer Indenture) under the terms required by the Buyer Indenture and shall use their commercially reasonable efforts to arrange the Repurchase Financing on the terms and conditions described in the Repurchase Commitment Letter, including using their commercially reasonable efforts to (i) satisfy on a timely basis all conditions applicable to the Buyer to obtaining the Repurchase Financing as set forth in the Repurchase Commitment Letter that are within its control; (ii) negotiate and enter into definitive agreements with respect thereto on the terms and conditions contemplated by the Repurchase Commitment Letter (including, if necessary, the flex provisions) or on other terms no less favorable to the Buyer; (iii) comply with the Buyer’s obligations under the Repurchase Commitment Letter and the definitive agreements with respect thereto; (iv) subject to the terms and conditions contemplated in the Repurchase Commitment Letter, conduct and consummate the Repurchase Financing at or prior to the time any repurchases of the Buyer Notes are required to be made under Section 4.15 of the Buyer Indenture; and (v) enforce its rights under the Repurchase Commitment Letter. If any portion of the Repurchase Refinancing becomes unavailable on the terms and conditions (including the flex provisions) contemplated in the Repurchase Commitment Letter or the

definitive agreements with respect thereto, the Buyer Parties shall promptly notify the MLP Parties and use their commercially reasonable efforts to amend, modify, supplement, alter, restate, substitute or replace the Repurchase Financing with other alternative financing, on terms no less favorable, taken as a whole, to Buyer, as promptly as possible; provided, however, that the Buyer Parties shall not permit any amendment, modification, supplement, alteration, restatement, substitution or replacement of the Repurchase Commitment Letter without the consent of the MLP Parties, such consent not to be unreasonably withheld. In such event, the term “Repurchase Commitment Letter” as used herein shall be deemed to include the amended, modified, supplemented, altered, restated, substituted or replacement, commitment letter.

in this Section 8.6 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Buyer Parties would not enter into this Agreement. Each of the MLP Parties further acknowledges and agrees that a Termination Fee is not a penalty, but rather liquidated damages in amounts reasonably estimated by the Parties to compensate the Buyer Parties for efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby. Accordingly, if MLP fails promptly to pay the amount due pursuant to this Section 8.6 and, in order to obtain such payment, Buyer commences a Proceeding which results in an order against MLP for the Termination Fee or Expense Reimbursement, MLP shall pay to Buyer its costs and expenses (including attorneys’ fees and expenses) in connection with such Proceeding, together with interest on any unpaid amount of the Termination Fee or Expense Reimbursement at the rate on six-month U.S. Treasury obligations plus 500 basis points in effect on the date such payment was required to be made, calculated on a daily basis from the date the Termination Fee or Expense Reimbursement was required to be paid until the date of the actual payment. Notwithstanding anything contained in this Agreement to the contrary, if a Termination Fee becomes due and payable and MLP pays a Termination Fee, none of the MLP Parties shall have any further liability of any kind for any reason in connection with this Agreement or the termination contemplated hereby. For the avoidance of doubt, under no circumstances shall MLP be required to pay more than one Termination Fee or more than one Expense Reimbursement.

(e) Any amounts paid to the Escrow Agent pursuant to this Section 8.6, together with interest thereon (the “Escrow Fund”), shall be released by the Escrow Agent to Buyer as follows:

(i) at any time prior to the end of the fiscal year in which the payment was made to the Escrow Agent, Buyer shall submit to the Escrow Agent a certificate demanding a portion of the Escrow Fund equal to no greater than 70% of the maximum remaining amount that, in the good faith view of Buyer, may still be taken into the gross revenues of Buyer and be treated as if such amount were not “qualifying income” (as defined in Section 7704 of the Code) while satisfying the qualifying income exception required for partnership treatment for publicly traded partnerships, after taking into consideration all other sources of non-qualifying income (such maximum remaining amount, the “Non-Qualifying Income Cushion”), and the Escrow Agent shall within one Business Day thereafter, pay Buyer the amount demanded, by wire transfer of immediately available funds to an account designated by the Buyer;

(ii) during the fiscal year following the date that the payment was made to the Escrow Agent but prior to the passage of 30 calendar days following the filing of the IRS Form 1065 for the prior fiscal year, Buyer shall submit to the Escrow Agent a certificate identifying the actual Non-Qualifying Income Cushion from the prior year. If the payment contemplated by clause (i) above was (A) less than 80% of the actual Non-Qualifying Income Cushion, then Buyer shall submit to the Escrow Agent a certificate demanding a portion of the Escrow Fund equal

to an amount which, when combined with the payment contemplated by clause (i) shall equal 90% of the actual Non-Qualifying Income Cushion, and the Escrow Agent shall within one Business Day thereafter, pay Buyer the amount demanded; (B) greater than or equal to 80%, but less than or equal to 90% of the actual Non-Qualifying Income Cushion, then Buyer shall notify the Escrow Agent that it shall not demand any additional payments from the Escrow Account; and (C) greater than 90% of the actual Non-Qualifying Income Cushion, then Buyer shall deliver a certificate to such effect to the Escrow Agent and return to the Escrow Fund an amount equal to the excess of the payment contemplated by clause (i) over 80% of the Non-Qualifying Income Cushion. Any payment under this clause (ii) shall be made by the Escrow Agent, or Buyer, as the case may be, by wire transfer of immediately available funds to an account designated by Buyer or the Escrow Agent, as the case may be; and

(iii) within one Business Day following the earlier of (A) completion of the procedures as contemplated by Section 8.6(e)(ii) above and (B) the passage of 30 days following the filing of the IRS Form 1065 for the prior fiscal year, the Escrow Agent shall pay MLP the remainder, if any, of the Escrow Fund, by wire transfer of immediately available funds to an account designated MLP.

(f) Each Party acknowledges and agrees that (i) the amount of a payment, if any, pursuant to clause (ii) of Section 8.6(e) is uncertain, and that depending on the amount of the demands made by Buyer pursuant to clause (ii) of Section 8.6(e), the Escrow Fund may be insufficient to permit payments to MLP pursuant to clause (iii) of Section 8.6(e); and (ii) MLP shall have no rights to any amounts in the Escrow Fund or to audit or inquire into the amounts demanded by or paid to Buyer.

(g) In the event Buyer exercises the “Option” as defined, and in accordance with, the Option Agreement, the Escrow Agent or Buyer, as applicable, shall return to MLP an amount equal to $21.8 million upon the full performance by MLP General Partner, CW Gas Holdings and CW Holdings of their obligations pursuant to Section 2.3(a) of the Option Agreement within three Business Days of the date of such performance. Section 8.6(e) shall apply mutatis mutandis in respect of any such return as if “MLP” was the “Buyer” referred to herein.

SECTION 8.7 Procedure for Termination. A termination of this Agreement pursuant to this Article VIII shall, in order to be effective, require, in the case of Buyer, action by the Buyer Board (or a committee thereof to which the Buyer Board has delegated decision making authority with respect to the applicable termination right), and, in the case of MLP, action by the MLP Board (or a committee thereof to which the MLP Board has delegated decision making authority with respect to the applicable termination right) or, in the case of a termination pursuant to Section 8.3(b), action by the MLP Conflicts Committee.

ARTICLE IX

MISCELLANEOUS

SECTION 9.1 Survival. None of the representations, warranties, agreements, covenants or obligations in this Agreement or in any instrument delivered pursuant to this Agreement shall survive the consummation of the Merger, except for those agreements, covenants and obligations contained herein (including Article III, Section 6.11 and Section 6.18) that by their terms are to be performed in whole or in part after the Effective Time and this Article IX).

SECTION 9.2 Enforcement of this Agreement. The Parties acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any Party and any such breach would cause the non-breaching Parties irreparable harm. Accordingly, the Parties agree that prior to the termination of this Agreement, in the event of any breach or threatened breach of this Agreement by one of the Parties, the Parties shall also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance. Such remedies shall not be the exclusive remedies for any breach of this Agreement but shall be in addition to all other remedies available at law or equity to each of the Parties.

SECTION 9.3 Notices. Any notice, request, instruction, correspondence or other document to be given hereunder by any Party to the Other Parties (each, a “Notice”) shall be in writing and delivered in Person or by courier service requiring acknowledgment of receipt of delivery or mailed by U.S. registered or certified mail, postage prepaid and return receipt requested, or by telecopier, as follows; provided, however, that copies to be delivered below shall not be required for effective notice and shall not constitute notice:

SECTION 9.4 Governing Law; Jurisdiction; Waiver of Jury Trial. To the maximum extent permitted by applicable Law, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without regard to principles of conflicts of law; provided, however, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York with respect to any action including any Financing Source. Each of the Parties agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708. Each of the Parties irrevocably and unconditionally confirms and agrees that it is and shall continue to be (a) subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware and (b) subject to service of process in the State of Delaware. Each Party hereby irrevocably and unconditionally (i) consents and submits to the exclusive jurisdiction of the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (and, if such court shall not have subject matter jurisdiction, any Delaware state court and the federal court of the United States located in the State of Delaware (together with the Delaware Court of Chancery, the “Delaware Courts”) for any Proceedings arising out of or relating to this Agreement or the transactions contemplated by this Agreement (and agrees not to commence any litigation relating thereto except in such courts); (ii) waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum; and (iii) acknowledges and agrees that any controversy which may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such Party hereby irrevocably and unconditionally waives any right such Party may have to a trial by jury in respect of any litigation directly or indirectly arising or relating to this Agreement or the transactions contemplated by this Agreement. Each of the Parties agrees that it will not, and will not permit its Affiliates to, bring or support any Proceeding of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against the Financing Sources in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including with respect to any dispute arising out of or relating in any way to the Debt Financing or the performance thereof, in any forum other than the United States District Court for the

Xxxxxxxx Xxxxxxxx xx Xxx Xxxx or any court of the State of New York sitting in the Borough of Manhattan in the City of New York and agree that the waiver of jury trial set forth in this Section 9.4 hereof shall be applicable to any such proceeding.

SECTION 9.5 Entire Agreement; Amendments and Waivers.

(a) Except for the Confidentiality Agreement, this Agreement and the exhibits and schedules hereto constitute the entire agreement between and among the Parties pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties, and there are no representations, warranties or other agreements between or among the Parties in connection with the subject matter hereof except as set forth specifically herein or contemplated hereby. Except as expressly set forth in this Agreement (including the representations and warranties set forth in Article IV and Article V), (i) the Parties acknowledge and agree that neither the MLP Group Entities nor any other Person has made, and the Buyer Group Entities are not relying upon, any covenant, representation or warranty, express or implied, as to the MLP Group Entities or as to the accuracy or completeness of any information regarding any MLP Group Entity furnished or made available to any Buyer Group Entity; and (ii) the MLP Parties shall not have or be subject to any liability to any Buyer Group Entity or any other Person, or any other remedy in connection herewith, based upon the distribution to any Buyer Group Entity of, or any Buyer Group Entity’s use of or reliance on, any such information or any information, documents or material made available to the Buyer Group Parties in any “data rooms,” “virtual data rooms,” management presentations or in any other form in expectation of, or in connection with, the transactions contemplated hereby.

(b) This Agreement may be amended by the Parties at any time before or after the MLP Unitholder Approval, but, after any such MLP Unitholder Approval was obtained, no amendment shall be made which by Law requires further approval by the unitholders of MLP without such further approval. No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the Party to be bound thereby. The failure of a Party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided. Notwithstanding the foregoing, no amendment shall be made to Section 9.4, Section 9.5, Section 9.6 or Section 9.10 which would be adverse to the Financing Sources without the prior written consent of such Financing Sources.

(c) Any amendments, supplements, waivers or modifications in respect of this Agreement pursuant to this Section 9.5 or any agreement to terminate this Agreement pursuant to Section 8.1 shall, in order to be effective, require, in the case of Buyer, action by the Buyer Board with the prior consent or recommendation of the Buyer Special Committee (or another committee to which the Buyer Board has delegated decision making authority with respect to the subject matter of such action) and, in the case of MLP, action by the MLP Board (or a committee thereof to which the MLP Board has

delegated decision making authority with respect to the subject matter of the amendment); provided, however, that no amendment of this Agreement that changes the form of, reduces the amount of or extends the timing of payment of, the Applicable Merger Consideration or alters the rights of the MLP Conflicts Committee or Buyer Special Committee hereunder shall be effective unless such amendment is also approved by the MLP Conflicts Committee or Buyer Special Committee, as applicable.

SECTION 9.6 Binding Effect; No Third Party Beneficiaries; Assignment.

(a) This Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns.

(b) None of the provisions of this Agreement shall be for the benefit of or enforceable by any third Person, including any creditor of any Party or any of their Affiliates, except (i) as provided in Section 6.11; (ii) as provided in Section 9.8; (iii) for the Financing Sources and their respective current former or future equity holders, controlling persons, Affiliates and Representatives, which shall be third party beneficiaries of Section 9.4, Section 9.5, Section 9.10 and this Section 9.6; and (iv) for the right of the MLP Unitholders the right to receive the Applicable Merger Consideration following the Effective Time and the right to be admitted as an Additional Limited Partner of Buyer in connection therewith. No such third Person shall obtain any right under any provision of this Agreement or shall by reason of any such provision make any claim in respect of any liability (or otherwise) against any Party. Without limiting the generality of the foregoing, nothing in this Agreement shall confer upon any employee, or legal representative or beneficiary thereof or other Person, any rights or remedies, including any right to employment or continued employment for any specified period, or compensation or benefits of any nature or kind whatsoever under this Agreement or a right in any employee or beneficiary of such employee or other Person under any Employee Benefit Plan that such employee or beneficiary or other Person would not otherwise have under the terms of such plan, nothing in this Agreement, express or implied, is intended to confer upon any Person other than the Parties and their respective permitted successors and assigns, any rights, benefits or obligations hereunder.

(c) No Party may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or alienation in violation of this Agreement shall be null, void and ineffective.

SECTION 9.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.

SECTION 9.8 No Recourse. This Agreement may only be enforced against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against the entities that are expressly identified as Parties and no former, current or future equity holders, controlling persons, directors, officers, employees, agents or Affiliates of any Party or any former, current or future equity holder, controlling person, director, officer, employee, general or limited partner, member, manager, agent or Affiliate of any of the foregoing (each, a “Non-Recourse Party”) shall have any liability for any obligations or liabilities of the Parties or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any representations made or alleged to be made in connection herewith. Without limiting the rights of any Party against the Other Parties, in no event shall any Party or any of its Affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any Non-Recourse Party.

SECTION 9.9 Execution. This Agreement may be executed in multiple counterparts each of which shall be deemed an original and all of which shall constitute one instrument. Delivery of an executed signature page of this Agreement by facsimile or other customary means of electronic transmission (e.g., “pdf”) shall be effective as delivery of a manually executed counterpart hereof.

SECTION 9.10 Certain Agreements with Respect to Financing Sources. The Parties agree on behalf of themselves and their respective equity holders, controlling persons, Affiliates, and Representatives (collectively, the “Related Parties”) that the Financing Sources and their and their respective current former or future equity holders, controlling persons, Affiliates or Representatives and each of their successors and assigns shall be subject to no liability or claims by the Related Parties arising out of or relating to this Agreement, the financing or the transactions contemplated hereby or in connection with the Debt Financing, or the performance of services by such Financing Sources or their Affiliates or Representatives with respect to the foregoing; provided, however that nothing in this Section 9.10 shall limit the rights that any Party would have pursuant to the Commitment Letters.
