ARTICLE III

MERGER CONSIDERATION; EXCHANGE PROCEDURES

3.1 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Parent GP Merger Sub, the Partnership, Partnership GP or any holder of Parent securities or Partnership Common Units, Partnership Class B Units or Partnership Class C Units:

(a) All of the limited liability company interests in Merger Sub outstanding immediately prior to the Effective Time will be automatically converted into the sole limited partner interest in the Partnership.

(b) The general partner interest in the Partnership issued and outstanding immediately prior to the Effective Time will remain outstanding in the Surviving Entity in the form set forth in the Existing Partnership Agreement, and the Partnership GP, as the holder of such general partner interest, will continue as the sole general partner of the Surviving Entity as set forth in the Existing Partnership Agreement. At the Effective Time, the books and records of the Partnership will be revised to reflect that all limited partners of the Partnership immediately prior to the Effective Time cease to be limited partners of the Partnership pursuant to the terms of this Agreement and that Parent is the sole limited partner of the Partnership, and the Partnership will continue without dissolution.

(c) Each Partnership Common Unit and Partnership Class B Unit issued and outstanding immediately prior to the Effective Time will be converted into the right to receive 0.9856 Parent Common Units (the “Merger Consideration,” and such ratio, the “Exchange Ratio”), which Parent Common Units will be duly authorized and validly issued in accordance with applicable Laws and the Parent Agreement, as applicable (such Parent Common Units described in this clause (c) are referred to herein as the “New Common Units”). Notwithstanding anything to the contrary in this Agreement, in no event will Parent be obligated to issue in excess of 72,001,686 New Common Units as part of the Merger Consideration.

(d) Each Partnership Class C Unit issued and outstanding immediately prior to the Effective Time will be converted into the right to receive cash in an amount equal to (i) $350 million divided by (ii) the number of Partnership Class C Units outstanding immediately prior to the Effective Time (the “Cash Consideration”), which shall be treated as a purchase of the Class C Units by Parent from such holders in accordance with Treas. Reg. §1.708-1(c)(4).

(e) Notwithstanding anything to the contrary in this Agreement, at the Effective Time, all Partnership Common Units, Partnership Class B Units and Partnership Class C Units (if any) owned by the Partnership or its wholly-owned Subsidiaries or by Parent or its wholly-owned Subsidiaries will automatically be cancelled and no consideration will be received therefor.

3.2 Rights As Unitholders; Unit Transfers. All Partnership Common Units and Partnership Class B Units converted into the right to receive the Merger Consideration pursuant to Section 3.1(c) and all Partnership Class C Units converted into the right to receive the Cash

Consideration pursuant to Section 3.1(d) will cease to be outstanding and will automatically be canceled and will cease to exist when converted as a result of and pursuant to the Merger. At the Effective Time, each holder of a certificate representing Partnership Common Units, Partnership Class B Units or Partnership Class C Units (a “Certificate”) and each holder of non-certificated Partnership Common Units, Partnership Class B Units or Partnership Class C Units represented by book-entry (“Book-Entry Units”) will cease to be a limited partner of the Partnership and cease to have any rights with respect thereto, except the right to receive, in the case of a holder of Partnership Common Units or Partnership Class B Units, (a) the Merger Consideration, and the right to be admitted as an additional limited partner of Parent in connection therewith, (b) any cash to be paid in lieu of any fractional New Common Unit in accordance with Section 3.3(d), and (c) any distributions in accordance with Section 3.3(c), and, in the case of a holder of Partnership Class C Units, the Cash Consideration, in each case, to be issued or paid, without interest, in consideration therefor in accordance with Section 3.3; provided, however, that the rights of (i) any holder of the Partnership Equity Awards will be as set forth in Section 3.5, and (ii) Parent and its Subsidiaries, and the Partnership and its Subsidiaries will be as set forth in Section 3.1(e). In addition holders as of the relevant record date of Partnership Common Units, Partnership Class B Units and Partnership Class C Units outstanding immediately prior to the Effective Time will have continued rights to any distribution, without interest, with respect to such Partnership Common Units, Partnership Class B Units and Partnership Class C Units with a record date occurring prior to the Effective Time that may have been declared or made by the Partnership with respect to such units in accordance with the terms of the Existing Partnership Agreement and this Agreement and which remains unpaid as of the Effective Time (a “Regular Distribution”). Regular Distributions by the Partnership are not part of the Merger Consideration or Cash Consideration, and will be paid on the payment date set therefor to such holders of Partnership Common Units, Partnership Class B Units and Partnership Class C Units whether or not they exchange their Partnership Common Units, Partnership Class B Units and Partnership Class C Units pursuant to Section 3.3. At the Effective Time, the unit transfer books of the Partnership will be closed immediately and there will be no further registration of transfers on the unit transfer books of the Partnership with respect to Partnership Common Units, Partnership Class B Units and Partnership Class C Units.

3.3 Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Parent will appoint a commercial bank or trust company reasonably acceptable to the Partnership to act as exchange agent hereunder for the purpose of exchanging Partnership Units for the Merger Consideration or Cash Consideration as required by this Article III (the “Exchange Agent”). Promptly after the Effective Time, Parent will deposit, or cause to be deposited, with the Exchange Agent for the benefit of the holders of the applicable Partnership Units, for exchange in accordance with this Article III, through the Exchange Agent, New Common Units and cash as required by this Article III. Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 3.3(c) and to make payments in lieu of any fractional New Common Units pursuant to Section 3.3(d), in each case without interest. Any cash (including as payment for any fractional New Common Units in accordance with Section 3.3(d) and any distributions with respect to such fractional New Common Units in accordance with Section 3.3(c)) and New Common Units deposited with the Exchange Agent are

hereinafter referred to as the “Exchange Fund.” The Exchange Agent will, pursuant to irrevocable instructions from Parent, deliver the Merger Consideration and Cash Consideration contemplated to be paid for Partnership Units pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 3.3(c) and 3.3(d), the Exchange Fund will not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Parent will instruct the Exchange Agent to mail to each record holder of Partnership Units as of the Effective Time (other than the Partnership and its Subsidiaries and Parent and its Subsidiaries) (i) a letter of transmittal (specifying that in respect of certificated Partnership Units, delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Exchange Agent, and which will be in customary form and agreed to by Parent and the Partnership prior to the Effective Time) (the “Letter of Transmittal”) and (ii) instructions (in customary form and agreed to by Parent and the Partnership prior to the Effective Time) for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration or Cash Consideration payable in respect of Partnership Units represented by such Certificates or Book-Entry Units, as applicable. 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 (including in respect of Book-Entry Units) as may be reasonably required pursuant to such instructions, (A) each holder who held Partnership Common Units or Partnership Class B Units immediately prior to the Effective Time (other than the Partnership and its Subsidiaries and Parent and its Subsidiaries) will be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor (x) New Common Units representing, in the aggregate, the whole number of New Common Units that such holder has the right to receive pursuant to Section 3.1(c) (after taking into account all Partnership Common Units or Partnership Class B Units then held by such holder) and (y) a check in an amount equal to the aggregate amount of the cash that such holder has the right to receive with respect to such Partnership Common Units or Partnership Class B Units pursuant to Section 3.3(c) and Section 3.3(d), and (B) each holder who held Partnership Class C Units immediately prior to the Effective Time (other than the Partnership and its Subsidiaries and Parent and its Subsidiaries) will be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor a check in an amount equal to the aggregate amount of the Cash Consideration, if any, payable in respect of such Partnership Class C Units that such holder has the right to receive pursuant to Section 3.1(d). No interest will be paid or accrued on any Merger Consideration, Cash Consideration, any cash payment in lieu of fractional New Common Units, any Parent distributions payable pursuant to Section 3.3(c) or any Regular Distribution. In the event of a transfer of ownership of Partnership Units that is not registered in the transfer records of the Partnership, the Merger Consideration or Cash Consideration, as applicable, and any Parent distributions payable pursuant to Section 3.3(c) payable in respect of such Partnership Units may be paid to a transferee, if the Certificate representing such Partnership Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both certificated and book-entry Partnership Units, accompanied by all documents reasonably required to evidence and effect such transfer and the Person requesting such exchange will pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration or Cash Consideration, as applicable, in

any name other than that of the record holder of such Partnership Units, or will 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 3.3, each Certificate or Book-Entry Unit will be deemed at any time after the Effective Time to represent only the right to receive upon such delivery and surrender the Merger Consideration or Cash Consideration, as applicable, payable in respect of Partnership Units, and any cash or distributions to which such holder is entitled pursuant to Section 3.3(c), Section 3.3(d) and (without the necessity of such surrender) Regular Distributions.

(c) Distributions with Respect to Unexchanged Partnership Common Units and Partnership Class B Units. No distributions declared or made with respect to Parent Common Units with a record date after the Effective Time will be paid to the holder of any Partnership Common Units or Partnership Class B Units with respect to New Common Units that such holder would be entitled to receive in accordance herewith and no cash payment in lieu of fractional New Common Units will be paid to any such holder until such holder has delivered the required documentation and surrendered any Certificates or Book-Entry Units as contemplated by this Section 3.3. Subject to applicable Law, following compliance with the requirements of Section 3.3(b), there will be paid to such holder of New Common Units issuable in exchange therefor, without interest, (i) promptly after the time of such compliance, the amount of any cash payable in lieu of fractional New Common Units to which such holder is entitled pursuant to Section 3.3(d) (which shall be paid by the Exchange Agent as provided therein) and the amount of distributions with a record date after the Effective Time theretofore paid with respect to New Common Units and payable with respect to such New Common Units, and (ii) promptly after such compliance, or, if later, at the appropriate payment date, the amount of distributions with a record date after the Effective Time but prior to such delivery and surrender and a payment date subsequent to such compliance payable with respect to such New Common Units (which shall be paid by Parent).

(d) Fractional New Common Units. No certificates or scrip of New Common Units representing fractional New Common Units or book entry credit of the same will be issued upon the surrender of Partnership Common Units or Partnership Class B Units outstanding immediately prior to the Effective Time in accordance with Section 3.3(b), and such fractional interests will not entitle the owner thereof to vote or to have any rights as a holder of any New Common Units. Notwithstanding any other provision of this Agreement, each holder of Partnership Common Units or Partnership Class B Units converted in the Merger who would otherwise have been entitled to receive a fraction of a New Common Unit (after taking into account all Partnership Common Units and Partnership Class B Units exchanged by such holder) will receive, in lieu thereof, cash (without interest rounded up to the nearest whole cent) in an amount equal to the product of (i) the Average Closing Price as of the Closing Date and (ii) the fraction of a New Common Unit that such holder would otherwise be entitled to receive pursuant to this Article III. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, Parent will cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof.

(e) Further Rights in Partnership Common Units.

(i) The Merger Consideration issued upon conversion of a Partnership Common Unit or Partnership Class B Unit in accordance with the terms hereof (including any cash paid pursuant to Section 3.3(d)) and any declared distributions to be paid on Parent Common Units as described in Section 3.3(c) will be deemed to have been issued in full satisfaction of all rights pertaining to such Partnership Common Unit or Partnership Class B Unit.

(ii) The Cash Consideration paid upon conversion of a Partnership Class C Unit in accordance with the terms hereof will be deemed to have been paid in full satisfaction of all rights pertaining to such Partnership Class C Units.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Partnership Units after 180 days following the Effective Time will be delivered to Parent upon demand by Parent and, from and after such delivery, any former holders of Partnership Units who have not theretofore complied with this Article III will thereafter look only to Parent for the Merger Consideration or Cash Consideration, as the case may be, payable in respect of such Partnership Units, any cash in lieu of fractional New Common Units to which they are entitled pursuant to Section 3.3(d), or any distributions with respect to New Common Units to which they are entitled pursuant to Section 3.3(c), in each case, without any interest thereon. Any amounts remaining unclaimed by holders of Partnership Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any governmental entity will, to the extent permitted by applicable Law, be held by Parent. Without limitation of the foregoing, after 180 days following the Effective Time any amounts remaining unclaimed by holders of Partnership Units will become the property of Parent, subject to the legitimate claims of any Person previously entitled thereto under abandoned property, escheat or similar laws.

(g) Lost Certificates. If any Certificate is 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 Parent, the posting by such Person of an indemnity agreement or a bond, in such amount reasonably determined by Parent, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration or Cash Consideration, as applicable, payable in respect of Partnership Units represented by such Certificate, any distributions to which the holders thereof are entitled pursuant to Section 3.3(c) and any cash payable in lieu of fractional New Common Units to which the holders thereof are entitled pursuant to Section 3.3(d).

(h) Withholding. Each of Parent, Merger Sub and the Exchange Agent are entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Partnership Units such amounts or securities as Parent, Merger Sub or the Exchange Agent reasonably deems to be 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; provided, however, that the Exchange Agent will provide reasonable notice to the

applicable holders of Partnership Units prior to deducting and withholding any amounts or securities pursuant to this Section 3.3(h). To the extent that amounts or securities are so deducted and withheld such amounts will be treated for all purposes of this Agreement as having been paid or issued to the holder of Partnership Units in respect of whom such deduction and withholding was made by Parent, Merger Sub or the Exchange Agent, as the case may be.

(i) Book Entry and Admission of Holders of New Common Units as Additional Limited Partners of Parent. All New Common Units to be issued in the Merger will be issued in book-entry form, without physical certificates. Upon the issuance of New Common Units to the holders of Partnership Common Units and Partnership Class B Units in accordance with this Section 3.3, and the compliance by such holders with the requirements of the Parent Agreement, which requirements may be satisfied by each holder of New Common Units by the execution and delivery by such holder of a completed and executed Letter of Transmittal, Parent GP will be deemed to have automatically consented to the admission of such holder as a limited partner of Parent in respect of its New Common Units and will reflect such admission on the books and records of Parent.

(j) Investment of the Exchange Fund. Parent will cause the Exchange Agent to invest the Exchange Fund as directed by Parent on a daily basis, in Parent’s sole discretion; provided, however, that no such investment or loss thereon affects the amounts payable or the timing of the amounts payable to the Partnership Unitholders pursuant to the other provisions of this Section 3.3. Any interest and other income resulting from such investments will be paid promptly to Parent.

(k) Tax Characterization of Merger and Cash Received. The Partnership and Parent each acknowledges and agrees that for federal income Tax purposes the transactions consummated pursuant to this Agreement will be treated as an “assets-over” partnership merger transaction under Treasury Regulations Sections 1.708-1(c)(1) and 1.708-1(c)(3)(i), whereby the Partnership will be the terminating partnership and Parent will be the resulting partnership. As a result, the transactions consummated pursuant to this Agreement shall be treated for U.S. federal income Tax purposes as a contribution of all of the assets of the Partnership to Parent in exchange for the Merger Consideration, the cash received in lieu of fractional Parent Common Units and the assumption of liabilities. To the maximum extent possible, any cash received in lieu of fractional Parent Common Units shall be treated as a reimbursement of preformation capital expenditures described in Treasury Regulation Section 1.707-4(d). To the extent the any cash received in lieu of fractional Parent Common Units exceeds the amount that can be so treated, such excess cash will be treated as proceeds of a disguised sale transaction described in Section 707(a)(2)(B) of the Code (a “Disguised Sale”). Each holder of Partnership Class C Units will be deemed to have consented for U.S. federal income tax purposes (and to the extent applicable, state or local income tax purposes) to report the Cash Consideration received in the Merger as proceeds from the sale of the holder’s Partnership Class C Units to Parent consistent with Treasury Regulation Section 1.708-1(c)(4). Each of the Partnership and Parent agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing and shall not take any position inconsistent therewith on any such Tax Return, or in the course of any audit, litigation or other proceeding with respect to U.S. federal income Taxes, except as otherwise required by applicable Laws following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Authority.

3.4 Anti-Dilution Provisions. Without limiting the covenants in Sections 4.1 and 4.2, in the event the outstanding Partnership Units or Parent Common Units shall have been changed into a different number of units or a different class after the date of this Agreement by reason of any subdivisions, reclassifications, splits, unit distributions, combinations or exchanges of Partnership Units or Parent Common Units, the Exchange Ratio will be correspondingly adjusted to provide to the holders of such Partnership Common Units and Partnership Class B Units the same economic effect as contemplated by this Agreement prior to such event.

3.5 Treatment of Awards under the Partnership LTIP. Immediately prior to the Effective Time, any award of Partnership Common Units issued under the Partnership LTIP that is subject to vesting or forfeiture conditions (“Partnership Restricted Units”), that is subject to time-based vesting and that is outstanding and unvested immediately prior to the Effective Time will, automatically and without any action on the part of the holder thereof, become fully vested and the restrictions with respect thereto shall lapse and such Partnership Restricted Units shall be converted into the right to receive the Merger Consideration pursuant to Section 3.1(c) on the terms applicable to issued and outstanding Partnership Common Units. Immediately prior to the Effective Time, any award of performance units with respect to Partnership Common Units that is outstanding immediately prior to the Effective Time (“Partnership Performance Units” and, together with the Partnership Restricted Units, “Partnership Equity Awards”) will, automatically and without action on the part of the holder thereof, vest and be settled in a number of Partnership Common Units determined based on actual attainment of the applicable performance goal(s) as of two Business Days prior to the Effective Time, and such resulting Partnership Common Units shall be converted at the Effective Time into the right to receive the Merger Consideration pursuant to Section 3.1(c) on the terms applicable to other issued and outstanding Partnership Common Units.

3.6 Treatment of Contingent Partnership Class B Units. Immediately prior to the Effective Time, a number of Contingent Class B Units issuable upon a Change of Control transaction (as used in Section 7.4 of the Existing Partnership Agreement) equal to the Adjusted Class B Amount automatically and without any action on the part of the holder thereof, shall vest and be issued, the restrictions with respect thereto shall lapse and such issued Contingent Class B Units shall be treated as issued and outstanding Partnership Class B Units as of immediately prior to the Effective Time and otherwise subject to the terms of this Agreement applicable to issued and outstanding Partnership Class B Units. For purposes of this Agreement, the “Adjusted Class B Amount” equals (x) 6,748,067 minus (y) the excess of (A) the number of Partnership Common Units issued in respect of the Partnership Performance Units in accordance with Section 3.5 over (B) 383,900 and minus (z) the number, if any, of Contingent Class B Units issued pursuant to Section 7.4(d) of the Existing Partnership Agreement.

7.1 Consummation of the Merger.

(a) Subject to the terms and conditions of this Agreement (including Section 7.1(d)), each of the Parent Entities, on the one hand, and the Partnership Entities, on the other hand, will cooperate with the other and use (and will cause their respective Subsidiaries to use) its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date) and to consummate and make effective, in the most expeditious manner practicable, the Merger, including preparing and filing promptly and fully all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings under applicable Antitrust Laws), (ii) obtain promptly (and in any event no later than the Outside Date) all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the Merger, (iii) defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Merger and (iv) obtain all necessary consents, approvals or waivers from third parties.

(b) In furtherance and not in limitation of the foregoing, each Party hereto agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable and in any event within 15 Business Days after the date of this Agreement and to supply as promptly as practicable any additional information and documentary material that may be requested by any Governmental Authority pursuant to the HSR Act or any other Antitrust Law and use its reasonable best efforts to take, or cause to be taken (including by their respective Subsidiaries), all other actions consistent with this Section 7.1 necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable (and in any event no later than the Outside Date). Parent will pay any HSR Act filing fee.

(c) Each of the Parties hereto will use its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission with a Governmental Authority in connection with the transactions contemplated hereby and in connection with any investigation or other inquiry by or before a Governmental Authority relating to the Merger, including any proceeding initiated by a private Person, (ii) promptly inform the Other Parties of (and supply to the Other Parties) any communication received by such Party from, or given by such Party to, the Federal Trade Commission, the Antitrust Division of the Department of Justice, or any other Governmental Authority and any material communication received or given in connection with any proceeding by a private Person, in each case regarding the Merger, (iii) permit the Other Parties to review in advance and incorporate the Other Parties’ reasonable comments in any communication to be given by it to any Governmental Authority with respect to obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and (iv) consult with the Other Parties in advance of any meeting or teleconference with any Governmental Authority or, in connection with any proceeding by a private Person, with any other Person, and, to the extent not prohibited by the Governmental Authority or other Person, give the Other Parties the opportunity to attend and participate in such meetings and teleconferences. Subject to Section 7.4(b), the Parties will take reasonable efforts to share information protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege pursuant to this Section 7.1 in a manner so as to preserve the applicable privilege.

(d) Parent agrees to take, or cause to be taken (including by its Subsidiaries), any and all steps and to make, or cause to be made (including by its Subsidiaries), any and all undertakings necessary to resolve such objections, if any, that a Governmental Authority may assert under any Antitrust Law with respect to the transactions contemplated hereby, and to avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the Merger, in each case, so as to enable the Closing to occur as promptly as practicable and in any event no later than the Outside Date, including, without limitation, (x) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any businesses, assets, equity interests, product lines or properties of Parent (or any of its Subsidiaries) or the Surviving Entity or any equity interest in any joint venture held by Parent (or any of its Subsidiaries) or the Surviving Entity, (y) creating, terminating or divesting relationships, ventures, contractual rights or obligations of Parent (or any of its Subsidiaries) or the Surviving Entity and (z) otherwise taking or committing to take any action that would limit Parent’s freedom of action with respect

to, or its ability to retain or hold, directly or indirectly, any businesses, assets, equity interests, product lines or properties of Parent (including any of its Subsidiaries) or the Surviving Entity or any equity interest in any joint venture held by Parent (or any of its Subsidiaries) or the Surviving Entity, in each case as may be required in order to obtain all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations required directly or indirectly under any Antitrust Law or to avoid the commencement of any action to prohibit the transactions contemplated hereby under any Antitrust Law, or, in the alternative, to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any action or proceeding seeking to prohibit the Merger or delay the Closing beyond the Outside Date. To assist Parent in complying with its obligations set forth in this Section 7.1, the Partnership will enter into one or more agreements requested by Parent to be entered into prior to the Closing with respect to any transaction to divest, hold separate or otherwise take any action that limits the Surviving Entity’s freedom of action, ownership or control with respect to, or their ability to retain or hold, directly or indirectly, any of the businesses, assets, equity interests, product lines or properties of the Surviving Entity or any equity interest in any joint venture held by the Surviving Entity (each, a “Divestiture Action”); provided, however, that the consummation of the transactions provided for in any such agreement for a Divestiture Action will be conditioned upon the Closing or satisfaction of all of the conditions to the Closing in a case where the Closing will occur immediately following such Divestiture Action (and where Parent has irrevocably committed to effect the Closing immediately following such Divestiture Action). Notwithstanding anything in this Agreement to the contrary, nothing in this Section 7.1 or elsewhere shall require, or be deemed to require, any Parent Entity or any of their respective Subsidiaries to take or agree to take any Divestiture Action if doing so would, individually or in the aggregate, result in a Material Adverse Effect on the Partnership and Parent, taken together.

(e) In furtherance and not in limitation of the covenants of the Parties contained in this Section 7.1, if any administrative or judicial action or proceeding, including any proceeding by a private Person, is instituted (or threatened to be instituted) challenging the Merger as violative of any Antitrust Law, each of Parent and the Partnership will use reasonable best efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Merger.

7.2 Registration Statement; Proxy Statement.

(a) As soon as practicable following the date of this Agreement (but no later than 20 Business Days after the date of this Agreement unless otherwise mutually agreed by the Parties), the Partnership will prepare and file with the SEC the Proxy Statement and Parent will prepare and Parent will file with the SEC the Registration Statement, in which the Proxy Statement will be included as a prospectus. Each of the Partnership and Parent will use its reasonable best efforts to have the Registration Statement declared effective under the Securities Act as promptly as practicable after such filing and keep the Registration Statement effective for so long as necessary to consummate the transactions contemplated hereby. Parent also agrees to use commercially reasonable efforts to obtain any necessary state securities law or “Blue Sky”

permits and approvals required to carry out the transactions contemplated by this Agreement. The Partnership will use its reasonable best efforts to cause the Proxy Statement to be mailed to the Partnership Unitholders as promptly as practicable after the Registration Statement is declared effective under the Securities Act. No filing of, or amendment or supplement to, the Registration Statement will be made by Parent, and no filing of, or amendment or supplement to, the Proxy Statement will be made by the Partnership without providing the Other Parties a reasonable opportunity to review and comment thereon. If at any time prior to the Effective Time any information relating to the Partnership or Parent, or any of their respective Affiliates, directors or officers, is discovered by the Partnership or Parent that should be set forth in an amendment or supplement to either the Registration Statement or the Proxy Statement, so that either such document 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 will promptly notify the Other Parties and an appropriate amendment or supplement describing such information will be promptly filed with the SEC and, to the extent required by Law, disseminated to the Partnership Unitholders. The Parties will notify each other promptly of the receipt of any comments from the SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Proxy Statement or the Registration Statement or for additional information and will supply each other with copies of (i) all correspondence between it or any of its Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Proxy Statement, the Registration Statement or the transactions contemplated hereby and (ii) all orders of the SEC relating to the Registration Statement.

(b) The Partnership will, as soon as reasonably practicable following the date of this Agreement, establish a record date for, and as soon as reasonably practicable following the Registration Statement being declared effective by the SEC, duly call, give notice of, convene and hold, the Partnership Meeting. The Partnership Meeting shall be held as promptly as practicable, and, if reasonably practicable, shall be held within 45 days after the mailing of the Proxy Statement. Subject to Section 7.3, the Partnership will, through the Partnership Board, (i) determine that the Merger is in the best interests of the Partnership and the Partnership Unitholders and (ii) recommend that the Partnership Unitholders approve this Agreement and the transactions contemplated hereby, including the Merger (the “Partnership Board Recommendation”). The Proxy Statement shall (subject to Section 7.3) include the Partnership Board Recommendation. The Partnership’s obligations to call, give notice of and hold the Partnership Meeting in accordance with Section 7.2(a) shall not be limited or otherwise affected by the making, commencement, disclosure, announcement or submission of any Superior Proposal or Alternative Proposal, or by any Partnership Change in Recommendation. Without limiting the generality of the foregoing, the Partnership agrees that: (i) unless this Agreement is validly terminated in accordance with Article IX (including, if applicable, upon payment of the Termination Fee and Parent Expenses), the Partnership shall not submit any Superior Proposal to a vote of the Partnership Unitholders; and (ii) the Partnership shall not (without Parent’s prior written consent) adjourn, postpone or cancel (or propose, publicly or otherwise, or resolve to, to adjourn, postpone or cancel) the Partnership Meeting. Notwithstanding anything in this Agreement to the contrary, the Partnership may postpone or adjourn the Partnership Meeting (i) in the absence of proxies sufficient to obtain the Partnership Unitholder Approval, to solicit

additional proxies for the purpose of obtaining Partnership Unitholder Approval, (ii) in the absence of a quorum, and (iii) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that the Partnership has determined after consultation with outside legal counsel is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the Partnership Unitholders prior to Partnership Meeting. Notwithstanding anything to the contrary in this Agreement, if there occurs a Partnership Change in Recommendation, the Partnership shall remain required to call, hold and convene the Partnership Meeting unless this Agreement has been terminated in accordance with its terms.

7.3 Alternative Proposals; Change in Recommendation.

(a) The Partnership will, and will cause its Subsidiaries and its and their respective directors, officers, and employees, and will use its reasonable best efforts to cause their respective other Representatives to, immediately cease and cause to be terminated any discussions or negotiations with any Person conducted heretofore with respect to an Alternative Proposal, and request the return or destruction of all confidential information previously provided to such Persons by or on behalf of the Partnership or its Subsidiaries. Except as permitted by this Section 7.3, the Partnership will not, and will cause its Subsidiaries and its and their respective directors, officers and employees not to, and will use reasonable best efforts to cause their respective other Representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiry, proposal or offer that would reasonably be expected to lead to an Alternative Proposal, or (ii) enter into or participate in any discussions or negotiations regarding, or furnish to any Person any non-public information with respect to, or that could reasonably be expected to lead to, any Alternative Proposal. Notwithstanding anything to the contrary contained in this Section 7.3, if at any time following the date of this Agreement and prior to obtaining the Partnership Unitholder Approval, (i) the Partnership has received a written Alternative Proposal which was not solicited after the date of this Agreement and that the Partnership Board believes is bona fide, and that did not result from a breach of this Section 7.3 and (ii) the Partnership Board, after consultation with its financial advisors and outside legal counsel, determines in good faith that such Alternative Proposal constitutes or would reasonably be expected to lead to or result in a Superior Proposal, then the Partnership may, subject to clauses (x) and (y) below, (A) furnish information, including confidential information, with respect to the Partnership and its Subsidiaries to the Person making such Alternative Proposal and (B) participate in discussions or negotiations regarding such Alternative Proposal; provided that (x) (I) at least 24 hours prior to furnishing any such non-public information to, or entering into discussions or negotiations with, such Person, the Partnership gives Parent written notice of the identity of such Person and the Partnership’s intention to furnish non-public information to, or enter into discussions or negotiations with, such Person and (II) the Partnership receives from such Person, and delivers to Parent a copy of, an executed confidentiality agreement containing provisions, including limitations on the use and disclosure of non-public written and oral information furnished to such Person by or on behalf of the Partnership, not materially less favorable to the Partnership than the provisions of the Confidentiality Agreement as in effect immediately prior to the execution of this Agreement, and (y) the Partnership will provide to Parent any non-public information about the Partnership and its Subsidiaries that was not previously provided or made available to Parent prior to or substantially concurrently with providing or making available such non-public information to such other Person.

(b) In addition to the obligations of the Partnership set forth in this Section 7.3, the Partnership will promptly (and in no event later than 24 hours after receipt) (i) advise Parent in writing of any Alternative Proposal (and any changes thereto) and the material terms and conditions of any such Alternative Proposal, including the identity of such Person making such Alternative Proposal, and (ii) provide Parent with copies of all written proposals or draft agreements received by the Partnership or any Representative of the Partnership setting forth the terms and conditions of, or otherwise relating to, such Alternative Proposal. The Partnership will keep Parent reasonably informed of all material developments with respect to the status and terms of any such Alternative Proposal, offers, inquiries or requests (and the Partnership shall promptly provide Parent with copies of any additional written proposals received by the Partnership or that the Partnership has delivered to any third party making an Alternative Proposal relating to such Alternative Proposal) and of the status of any such discussions or negotiations. The Partnership Parties agree that neither Partnership Party nor any of the Subsidiaries of the Partnership will enter into any agreement with any person subsequent to the date of this Agreement which prohibits the Partnership from providing any information to Parent in accordance with this Section 7.3.

(c) Except as otherwise provided in this Section 7.3, the Partnership Board shall not: (i) (A) withdraw, modify or qualify in any manner adverse to Parent the Partnership Board Recommendation, (B) fail to include the Partnership Board Recommendation in the Proxy Statement or (C) publicly approve or recommend, or publicly propose to approve or recommend, any Alternative Proposal (any action described in this Section 7.3(c)(i) being referred to as a “Partnership Change in Recommendation”); (ii) approve, adopt or recommend, or publicly propose to approve, adopt or recommend, or allow the Partnership or any of its Subsidiaries 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 contract or any tender or exchange offer providing for, with respect to, or in connection with, any Alternative Proposal; (iii) fail to announce publicly within 10 Business Days after a tender offer or exchange offer relating to the Partnership Units shall have been commenced that the Partnership Board recommends rejection of such tender offer or exchange offer and reaffirming the Partnership Board Recommendation; or (iv) resolve, agree or publicly propose to, or permit the Partnership or any Representative of the Partnership to agree or publicly propose to take any of the actions referred to in this Section 7.3(c). For the avoidance of doubt, a public statement that describes the Partnership’s receipt of an Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed a Partnership Change in Recommendation.

(d) Notwithstanding the foregoing, if (i) the Partnership receives a written Alternative Proposal (and such proposal is not withdrawn) that the Partnership Board believes is bona fide, (ii) such Acquisition Proposal did not result from a breach of this Section 7.3 and (iii) the Partnership Board determines, after consultation with its financial advisors and outside legal counsel, that such Alternative Proposal constitutes a Superior Proposal, then the Partnership Board may at any time prior to obtaining the Partnership Unitholder Approval, terminate this

Agreement and pay Parent a Termination Fee and/or effect a Partnership Change in Recommendation; provided, however, that the Partnership Board may not take such action pursuant to the foregoing unless:

(i) the Partnership has provided prior written notice to Parent specifying in reasonable detail the reasons for such action (including a description of the material terms of such Superior Proposal and delivering to Parent a copy of the proposed definitive agreement providing for the Alternative Proposal for such Superior Proposal in the form to be entered into and any other relevant proposed transaction agreements, at least three Business Days in advance of its intention to take such action with respect to a Partnership Change in Recommendation, unless at the time such notice is otherwise required to be given there are less than three Business Days prior to the Partnership Meeting, in which case the Partnership will provide as much notice as is reasonably practicable (the period inclusive of all such days, the “Notice Period”) (it being understood and agreed that any material amendment to the terms of a Superior Proposal shall require a new notice pursuant to this Section 7.3(d)(i) and a new Notice Period, except that such new Notice Period in connection with any amendment shall be for two Business Days from the time Parent receives such notice (as opposed to three Business Days)); and

(ii) during the Notice Period the Partnership has negotiated with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute (in the determination of the Partnership Board, after consultation with its financial advisors and outside legal counsel) a Superior Proposal.

(e) The Partnership Board is permitted, at any time prior to obtaining the Partnership Unitholder Approval, other than in connection with an Alternative Proposal, to make a Partnership Change in Recommendation in response to an Intervening Event but only if (i) prior to taking any such action, the Partnership Board determines in good faith, after consultation with and considering the advice of the Partnership’s outside legal counsel, that failure to take such action would be inconsistent with its duties under applicable Delaware law, the Existing Partnership Agreement or the Partnership GP Agreement, (ii) the Partnership has given at least three Business Days’ advance written notice to Parent that the Partnership Board intends to take such action (which notice shall specify in reasonable detail the reasons for such action) and (iii) during such period the Partnership has negotiated, and has used reasonable best efforts to cause its financial advisors and outside legal counsel to negotiate, with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so as to permit the Partnership Board (in its judgment, after consultation with its financial advisors and outside legal counsel) not to make the determination described in clause (i). If after compliance with the foregoing clauses (i) – (iii) the Partnership Board determines in good faith, after consultation with its financial advisors and outside legal counsel, that the failure to make a Partnership Change in Recommendation would be inconsistent with its duties under applicable Delaware law, the Existing Partnership Agreement or the Partnership GP Agreement, then the Partnership Board may, at any time prior to obtaining the Partnership Unitholder Approval, effect a Partnership Change in Recommendation. An “Intervening Event” means a material event, circumstance, state of facts, occurrence,

development or change that did not exist or was not known to the Partnership Board on the date of this Agreement (or if known, the consequences of which were not known or reasonably foreseeable by the Partnership Board as of the date of this Agreement), which event, circumstance, state of facts, occurrence, development or change, or any material consequences thereof, becomes known to the Partnership Board prior to the receipt of the Partnership Unitholder Approval; provided, however, that (A) in no event shall the receipt, existence, potential for or terms of an Alternative Proposal or any matter relating thereto or consequence thereof constitute an Intervening Event and (B) if the Intervening Event relates to a change, event, development, circumstance, condition, occurrence or effect involving the Partnership, then none of the following changes, events, developments, circumstances, conditions, occurrences or effects shall constitute an Intervening Event: (1) changes in the general economic, financial, credit or securities markets, including prevailing interest rates or currency rates, or regulatory or political conditions and changes in oil, natural gas, condensate or natural gas liquids prices or prices of other commodities, including changes in price differentials; (2) changes in general economic conditions in the (v) oil and gas exploration and production industry, (w) natural gas gathering, compressing, treating, processing and transportation industry generally, (x) the natural gas liquids fractionating and transportation industry generally, (y) the crude oil and condensate logistics and marketing industry generally, and (z) the natural gas marketing and trading industry generally (including in each case changes in law affecting such industries); (3) the announcement or pendency of this Agreement (including, for the avoidance of doubt, performance of obligations under this Agreement); and (4) changes in any Laws or regulations applicable to the Partnership or applicable accounting regulations or the interpretations thereof.

(f) Nothing contained in this Agreement will prevent the Partnership or the Partnership Board from taking and disclosing to the Partnership Unitholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act (or any similar communication to the Partnership Unitholders) or from making any legally required disclosure to Partnership Unitholders. Any “stop-look-and-listen” communication by the Partnership or the Partnership Board to the Partnership Unitholders pursuant to Rule 14d-9(f) promulgated under the Exchange Act (or any similar communication to the Partnership Unitholders) will not be considered a failure to make, or a withdrawal, modification or change in any manner adverse to Parent of, all or a portion of the Partnership Board Recommendation.

(g) The Partnership agrees that it will not release or permit the release of any Person from, or amend, waive or permit the amendment or waiver of any provision of, any “standstill” or similar agreement or provision to which the Partnership is or becomes a party or under which the Partnership has any rights, and will use its reasonable best efforts to enforce each such agreement or provision at the request of Parent.

(h) The Partnership acknowledges and agrees that any action inconsistent with any provision set forth in this Section 7.3 that is taken by a Representative of the Partnership that, if taken by the Partnership would have been a breach of this Section 7.3, shall be deemed to constitute a breach of such provision by the Partnership.

(i) Promptly, but in any event no later than 24 hours after the date of this Agreement, the Partnership shall request each Person that has executed a confidentiality or

similar agreement in connection with such Person’s consideration of a possible Alternative Proposal to return or destroy all confidential information previously furnished to such Person by or on behalf of the Partnership.

(j) For purposes of this Agreement:

(i) “Alternative Proposal” means any proposal or offer, which was not solicited after the date of this Agreement, from any Person or “group” (as defined in Section 13(d) of the Exchange Act), other than Parent and its Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions), of assets of the Partnership equal to 20% or more of the consolidated assets of the Partnership or to which 20% or more of the Partnership’s revenues or earnings are attributable, (B) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of beneficial ownership (within the meaning of Section 13(d) of the Exchange Act) of 20% or more of any class of the Partnership’s equity securities, (C) tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning 20% or more of any class of the Partnership’s equity securities, or (D) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Partnership which is structured to permit such Person or group to acquire beneficial ownership of at least 20% of the Partnership’s consolidated assets or equity interests; in each case, other than the transactions contemplated by this Agreement.

(ii) “Superior Proposal” means a written offer, which was not solicited after the date of this Agreement and which was obtained after the date of this Agreement, to acquire, directly or indirectly, more than 75% of the outstanding equity securities of the Partnership or more than 75% of the assets of the Partnership and its Subsidiary, made by a third party, which did not result from a breach of Section 7.3, is on terms and conditions which the Partnership Board determines in good faith, after consultation with its financial advisors and outside legal counsel, to be more favorable from a financial point of view to the Partnership Unitholders than the transactions contemplated by this Agreement, taking into account at the time of determination (a) relevant financial considerations, (b) the identity of the person making such offer, (c) the anticipated timing, conditions and prospects for completion of the transactions contemplated by such offer, (d) the other terms and conditions of such offer and the implications thereof on the Partnership, including relevant legal, regulatory and other aspects of such offer and (e) any changes to the terms of this Agreement that as of that time had been committed to by Parent in writing.

7.4 Access to Information; Confidentiality.

(a) Upon reasonable notice, each Party shall, and shall cause each of its Subsidiaries to afford to the Other Parties and their respective Representatives reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of its and its Subsidiaries’ properties, commitments, books, contracts, records and correspondence (in each case, whether in physical or electronic form), officers, employees, accountants, counsel, financial advisors and other Representatives. Each Party shall furnish promptly to the Other

Parties (i) a copy of each report, schedule and other document filed or submitted by it pursuant to the requirements of federal or state securities Laws and a copy of any communication (including “comment letters”) received by such Party from the SEC concerning compliance with securities Laws and (ii) all other information concerning its and its Subsidiaries’ business, properties and personnel as the Other Parties may reasonably request, including information necessary to prepare the Proxy Statement and the Registration Statement. Without limiting the foregoing, the Partnership shall deliver or cause to be delivered to Parent (1) on a monthly basis reports specifying the capital expenditures, operating expenses, production and completed and in-progress activities of the Partnership and its Subsidiaries, together with a comparison to the relevant items in the Partnership 2014 Budget, and (2) weekly operating reports, in each case, to the extent as prepared by the Partnership in the ordinary course of business consistent with past practice. Except for disclosures permitted by the terms of the Confidentiality Agreement, each Party and its Representatives shall hold information received from the Other Parties pursuant to this Section 7.4 in confidence in accordance with the terms of the Confidentiality Agreement.

(b) This Section 7.4 shall not require any Party to permit any access, or to disclose any information, that in the reasonable, good faith judgment (after consultation with counsel, which may be in-house counsel) of such Party would reasonably be expected to result in (i) any violation of any contract or Law to which such Party or its Subsidiaries is a party or subject or cause any privilege (including attorney-client privilege) that such Party or any of its Subsidiaries would be entitled to assert to be undermined with respect to such information and such undermining of such privilege could in such Party’s good faith judgment (after consultation with counsel, which may be in-house counsel) adversely affect in any material respect such Party’s position in any pending or, what such Party believes in good faith (after consultation with counsel, which may be in-house counsel) could be, future litigation or (ii) if such Party or any of its Subsidiaries, on the one hand, and any Other Party or any of its Subsidiaries, on the other hand, are adverse parties in a litigation, such information being reasonably pertinent thereto; provided that, in the case of clause (i), the Parties shall cooperate in seeking to find a way to allow disclosure of such information (including by entering into a joint-defense or similar agreement) to the extent doing so (1) would not (in the good faith belief of the Party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) reasonably be expected to result in the violation of any such contract or Law or reasonably be expected to cause such privilege to be undermined with respect to such information or (2) could reasonably (in the good faith belief of the Party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) be managed through the use of customary “clean-room” arrangements pursuant to which non-employee Representatives of the Other Party shall be provided access to such information; provided, further, that the Party being requested to disclose the information shall (x) notify the Other Parties that such disclosures would reasonably be expected to violate its or its Subsidiaries’ obligations under any such contract or Law or would reasonably be expected to cause such privilege to be undermined and (y) communicate to the Other Parties in reasonable detail the facts giving rise to such notification and the subject matter of such information (to the extent it is able to do so in accordance with the first proviso in this Section 7.4(b)) and (z) in the case where such disclosures would be reasonably expected to violate its or its Subsidiaries’ obligations under any contract, use reasonable commercial efforts to seek consent from the applicable third party to any such contract with respect to the disclosures prohibited thereby (to the extent not otherwise expressly prohibited by the terms of such contract).

7.5 Public Statements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and the Partnership. Parent and the Partnership will not, and each of the foregoing will cause its Representatives not to, issue any public announcements or make other public disclosures regarding this Agreement or the transactions contemplated hereby, without the prior written approval of the Parties; provided, however, that a Party or its Representatives may issue a public announcement or other public disclosures required by Law or the rules of any stock exchange upon which such Party’s or its Parent entity’s capital stock is traded, provided such Party uses reasonable best efforts to afford the Other Party an opportunity to first review the content of the proposed disclosure and provide reasonable comment regarding same; provided, however, that this Section 7.5 shall not be deemed to restrict in any manner the Partnership’s ability to communicate with its employees and that the Partnership shall not be required by this Section 7.5 to consult with any Other Party with respect to a public announcement in connection with the receipt and existence of an Alternative Proposal and matters related thereto or a Partnership Change in Recommendation, but nothing in this Section 7.5 shall limit the Partnership’s obligations under Section 7.3.

7.6 Confidentiality. The obligations of Parent and the Partnership under the Confidentiality Agreement shall remain in full force and effect and all information provided to any Party or its Representatives pursuant to or in connection with this Agreement is deemed to be “Evaluation Material” as defined under the Confidentiality Agreement; provided, however, that nothing in the Confidentiality Agreement shall be deemed to restrict the performance by the Partnership Parties or the Parent Parties of their respective obligations under this Agreement, and in the case of any conflict between the terms of this Agreement and the terms of the Confidentiality Agreement the terms of this Agreement shall control.

7.7 Takeover Laws. Neither the Partnership nor Parent will take any action that would cause the transactions contemplated by this Agreement to be subject to requirements imposed by any Takeover Laws, and each of them will take all reasonable steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement from the Takeover Laws of any state that purport to apply to this Agreement or the transactions contemplated hereby.

7.8 New Common Units Listed. Parent will use its commercially reasonable efforts to list, prior to the Closing, on the NASDAQ, upon official notice of issuance, the New Common Units.

7.9 Third-Party Approvals.

(a) Subject to the terms and conditions of this Agreement, Parent and the Partnership and their respective Subsidiaries will cooperate and use their respective commercially reasonable efforts to prepare all documentation, to effect all filings, to obtain all permits, consents, approvals and authorizations of all Governmental Authorities and third parties

necessary to consummate the transactions contemplated by this Agreement and to comply with the terms and conditions of such permits, consents, approvals and authorizations and to cause the Merger to be consummated as expeditiously as practicable. Each of Parent and the Partnership has the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable Laws relating to the exchange of information, with respect to, all material written information submitted to any third party or any Governmental Authorities in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the Parties agrees to act reasonably and promptly. Each Party agrees that it will consult with the Other Parties with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement, and each Party will keep the Other Parties apprised of the status of material matters relating to completion of the transactions contemplated hereby.

(b) Each of Parent and the Partnership agrees, upon request, to furnish the Other Party with all information concerning itself, its Subsidiaries, directors, officers and unitholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the Registration Statement or any filing, notice or application made by or on behalf of such Other Party or any of such Other Party’s Subsidiaries to any Governmental Authority in connection with the transactions contemplated hereby.

(c) This Section 7.9 shall not apply to (i) approval under Antitrust Laws or (ii) approval of the SEC of the Registration Statement and Proxy Statement.

7.10 Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any additional rights that any director, officer, trustee, employee, agent, or fiduciary may have under any employment or indemnification agreement or under the Existing Partnership Agreement, the Director and Officer Indemnification Agreements, this Agreement or, if applicable, similar organizational documents or agreements of any of the Partnership’s Subsidiaries, from and after the Effective Time, Parent and the Surviving Entity, jointly and severally, will: (i) indemnify and hold harmless each person who is now, or has been or becomes at any time prior to the Effective Time, an officer, director or employee of the Partnership GP, the Partnership or any of its Subsidiaries and also with respect to any such Person, in their capacity as a director, officer, employee, member, trustee or fiduciary of another corporation, foundation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (whether or not such other entity or enterprise is affiliated with the Partnership) serving at the request of or on behalf of the Partnership GP, the Partnership or any of its Subsidiaries and together with such Person’s heirs, executors or administrators (collectively, the “Indemnified Parties”) to the fullest extent authorized or permitted by applicable Law in connection with any Claim or Action against any losses, claims, damages, liabilities, costs, Indemnification Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) resulting therefrom; and (ii) promptly pay on behalf of or, within 15 days after any request for advancement, advance to each of the Indemnified Parties, any Indemnification Expenses incurred in defending, serving as a witness with respect to or otherwise participating

with respect to any Claim or Action in advance of the final disposition of such Claim or Action, including payment on behalf of or advancement to the Indemnified Party of any Indemnification Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security. The indemnification and advancement obligations of Parent and the Surviving Entity pursuant to this Section 7.10(a) extend to acts or omissions occurring at or before the Effective Time and any Claim or Action relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger and the transactions contemplated by this Agreement, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim or Action relating thereto), and all rights to indemnification and advancement conferred hereunder continue as to any Indemnified Party who has ceased to be a director or officer of the Partnership or any of its Subsidiaries after the date of this Agreement and inure to the benefit of such person’s heirs, executors and personal and legal representatives. As used in this Section 7.10: (x) the term “Claim” means any threatened, asserted, pending or completed action or proceeding, whether instituted by any Party, any Governmental Authority or any other person, that any Indemnified Party in good faith believes might lead to the institution of any action or proceeding, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism (“Action”), arising out of or pertaining to matters that relate to such Indemnified Party’s duties or service as a director or officer of the Partnership GP or of any of its Subsidiaries or as a trustee of (or in a similar capacity with) any compensation and benefit plan of any thereof; (y) the term “Indemnification Expenses” means documented out-of-pocket attorneys’ fees and expenses and all other reasonable and documented out-of-pocket costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim for which indemnification is sought pursuant to this Section 7.10(a), including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party; and (z) the phrase “to the fullest extent authorized or permitted by applicable Law” includes, but is not limited to (1) to the fullest extent authorized or permitted by any provision of the DRULPA and the DLLCA that authorizes or permits additional indemnification by agreement or otherwise, or the corresponding provision of any amendment to or replacement of the DRULPA and the DLLCA and (2) to the fullest extent authorized or permitted by any amendments to or replacements of the DRULPA and the DLLCA adopted after the date of this Agreement that increase the extent to which an entity may indemnify its directors, officers, trustees, employees, agents, or fiduciaries or persons serving in any capacity in which any Indemnified Party serves. Any amendment, alteration or repeal of the DRULPA or the DLLCA that adversely affects any right of any Indemnified Party will be prospective only and does not limit or eliminate any such right with respect to any Claim or Action involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal. Neither Parent nor the Surviving Entity will settle, compromise or consent to the entry of any judgment in any actual or threatened Claim or Action in respect of which indemnification has been or could be sought by such Indemnified Party hereunder unless such settlement, compromise or judgment includes an

unconditional release of such Indemnified Party from all liability arising out of such Claim or Action without admission or finding of wrongdoing, or such Indemnified Party otherwise consents thereto.

(b) Without limiting the foregoing, Parent and Merger Sub agree that all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the Indemnitees as provided in the Existing Partnership Agreement (or, as applicable, the charter, bylaws, partnership agreement, limited liability company agreement, or other organizational documents of any of the Partnership GP or the Partnership’s Subsidiaries) and indemnification agreements (including, without limitation, the Director and Officer Indemnification Agreements) of the Partnership GP, the Partnership or any of its Subsidiaries will be assumed by the Surviving Entity and Parent in the Merger, without further action, at the Effective Time and will survive the Merger and continue in full force and effect in accordance with their terms.

(c) For a period of six years from the Effective Time, the Existing Partnership Agreement and the organizational documents of the Partnership’s Subsidiaries, including any applicable amendments thereto or restatements thereof, will contain provisions no less favorable with respect to indemnification, advancement of expenses, exculpation and limitations on liability of directors and officers than are set forth in the Existing Partnership Agreement and Director and Officer Indemnification Agreements, which provisions will not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were Indemnified Parties, unless such modification is required by Law and then only to the minimum extent required by Law; provided, however, that any such modification shall be prospective only and shall not limit or eliminate any such right with respect to any Claim or Action involving any occurrence or alleged occurrence of any action or omission to act that took place prior to modification; and provided further that all rights to indemnification in respect of any Action pending or asserted or any Claim made within such period continue until the disposition of such Action or resolution of such Claim.

(d) For a period of six years from the Effective Time, Parent will maintain in effect the current directors’ and officers’ liability and fiduciary liability insurance policies covering the Indemnified Parties (but may substitute therefor other policies of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the Indemnified Parties so long as that substitution does not result in gaps or lapses in coverage or are alleged to have occurred) with respect to matters occurring on or before the Effective Time, but Parent is not required to pay annual premiums in excess of 300% of the last annual premiums paid therefor prior to the date of this Agreement (the “Maximum Amount”) and will purchase the maximum amount of coverage that can be obtained for that amount if the coverage described in this Section 7.10(d) would cost in excess of that amount. If Parent elects, then Parent may, on or prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such; provided that in no event shall the cost of such policy, if purchased by the Partnership, exceed six times the Maximum Amount and, if such a “tail policy” is purchased, neither Parent nor the Surviving Entity shall have any further obligations under this Section 7.10(d).

(e) If Parent, the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges with or into any other person and is not the continuing or surviving corporation, partnership or other entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision will be made so that the successors and assigns of Parent or the Surviving Entity assume the obligations set forth in this Section 7.10.

(f) Parent will cause the Surviving Entity to perform all of the obligations of the Surviving Entity under this Section 7.10.

(g) This Section 7.10 survives the consummation of the Merger and is intended to be for the benefit of, and to be enforceable by, the Indemnified Parties and the Indemnitees and their respective heirs and personal representatives, and will be binding on Parent, the Surviving Entity and their respective successors and assigns.

7.11 Notification of Certain Matters. The Partnership shall give prompt notice to Parent, and Parent shall give prompt notice to the Partnership, to the extent in each case it obtains Knowledge thereof of (i) any notice or other communication received by such Party from any Governmental Authority in connection with the transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, if the subject matter of such communication or the failure of such Party to obtain such consent would reasonably be expected to be material to the Partnership or Parent, (ii) any actions, suits, claims, investigations or proceedings commenced or threatened against, relating to or involving or otherwise affecting such Party or any of its Subsidiaries and that relate to the Merger, (iii) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would result in the failure to be satisfied of any of the conditions to the Closing in Article VIII and (iv) any material failure of such Party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereby which would result in the failure to be satisfied of any of the conditions to the Closing in Article VIII; provided that, in the case of clauses (iii) and (iv), the failure to comply with this Section 7.11 shall not result in the failure to be satisfied of any of the conditions to the Closing in Article VIII, or give rise to any right to terminate this Agreement under Article IX, if the underlying fact, circumstance, event or failure would not in and of itself give rise to such failure or right.

7.12 Section 16 Matters. Prior to the Effective Time, Parent and the Partnership will take all such steps as may be required (to the extent permitted under applicable Law) to cause any dispositions of Partnership Common Units (including derivative securities with respect to Partnership Common Units) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Partnership, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

7.13 [Intentionally Omitted]

7.14 Distributions. Each of the Partnership and Parent will consult with the Other Party regarding the declaration and payment of distributions in respect of Partnership Common Units, Partnership Class B Units, Partnership Class C Units and the Parent Common Units and the record and payment dates relating thereto, so that no Partnership Unitholder receives two distributions, or fails to receive one distribution, for any single calendar month with respect to its applicable Partnership Common Units, Partnership Class B Units, Partnership Class C Units or any Parent Common Units any such Partnership Unitholder receives in exchange therefor pursuant to the Merger.

7.15 Employee Benefits.

(a) At least five business days prior to the Closing, Parent or an Affiliate of Parent shall extend offers of employment, which offers shall be effective as of the Closing, to (i) each Employee that is a field-level Employee and (ii) each Employee employed in the positions to be offered on Schedule 7.15(a) (collectively, the “Business Employees”). The Partnership shall cooperate with Parent to make the Business Employees reasonably accessible to the Parent and to assist Parent in its efforts to secure satisfactory employment arrangements with any Business Employees. The Partnership shall, or shall use reasonable efforts to cause QRM to, terminate for all purposes (including under all Partnership Employee Benefit Plan) the employment of each Business Employee. Each Business Employee who commences employment with Parent or an Affiliate thereof, effective as of the Closing, shall hereinafter be referred to as a “Continuing Employee” as of the Closing.

(b) For a period of twelve months following the Effective Time, Parent shall, and shall cause its Affiliates to, provide each of the Continuing Employees with (i) a base salary or wage rate, as applicable, that is no less favorable than such Continuing Employee’s base salary or wage rate as of immediately prior to the Effective Time, (ii) a target annual cash bonus opportunity that is no less favorable than the target annual cash bonus opportunity provided to such Continuing Employee as of immediately prior to the Effective Time, and (iii) other health and welfare employee benefits (but, for clarity, excluding equity-based compensation and retiree welfare and defined benefit plans) that are substantially comparable, in the aggregate, to the employee benefits provided to such Continuing Employee as of immediately prior to the Effective Time.

(c) Without limiting Section 7.15(b), Parent shall, or shall cause its Affiliates to , provide to the Business Employees whose employment is terminated at or following the Effective Time with the severance payments and benefits in accordance with the terms and conditions mutually agreed to between Parent and the Partnership prior to Closing.

(d) Effective as of the Effective Time, Parent will, or will cause its Affiliates to, cause each compensation or employee benefit plan maintained by Parent or any of its Affiliates and in which any Continuing Employee becomes eligible to participate in, to treat the prior service of such Continuing Employee with any of Partnership, QRM and their respective Affiliates as service rendered to Parent or its Affiliates, as the case may be, for all purposes

(including vesting, eligibility, level of benefit and benefit accrual purposes, but other than for purposes of benefit accrual under any defined benefit plan or retiree welfare plan or vesting under any equity compensation plan) to the extent that such service crediting does not violate any applicable Law or result in duplication of benefits for the same period of service.

(e) Parent will, or will cause its Affiliates to, use commercially reasonable efforts to (i) waive any limitation on health and welfare coverage of any Continuing Employee and his or her eligible dependents due to pre-existing conditions and/or waiting periods, active employment requirements, and requirements to show evidence of good health under the applicable health and welfare plan of Parent or any Affiliate of Parent to the extent such Continuing Employee and his or her eligible dependents are covered under a health and welfare benefit plan of the Partnership, QRM or any of their respective Affiliates (as the case may be), and such conditions, periods or requirements are satisfied or waived under such plan, immediately prior to the Effective Time and (ii) credit each Continuing Employee and his or her eligible dependents with all deductible payments, co-payments and co-insurance paid by such employee and covered dependents under the medical employee benefit plan of the Partnership, QRM or any of their respective Affiliates (as the case may be) prior to the Effective Time during the year in which the Effective Time occurs for the purpose of determining the extent to which any such employee and his or her dependents have satisfied their deductible and whether they have reached the out-of-pocket maximum under the applicable medical plan of Parent or any Affiliate of Parent for such year.

(f) For purposes of determining the number of vacation days and other paid time off to which each Continuing Employee is entitled during the calendar year in which the Effective Time occurs, Parent will, to the extent permitted by applicable Law, assume and honor all vacation and other paid time off days accrued or earned but not yet taken by such Continuing Employee as of the Effective Time.

(g) Unless otherwise notified by Parent in writing, prior to the Effective Time, the Partnership shall take or cause to be taken any and all actions necessary or appropriate, including board approvals, to terminate the Partnership LTIP effective as of and contingent upon the Closing.

(h) The provisions of this Section 7.15 are for the sole benefit of the Parties and nothing herein, expressed or implied, is intended or will be construed to confer upon or give to any person (including, for the avoidance of doubt, any Employee, Business Employee or Continuing Employee or other current or former employee of the Partnership, QRM or any of their respective Affiliates), other than the Parties and their respective permitted successors and assigns, any legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 7.15) under or by reason of any provision of this Agreement. Nothing in this Section 7.15 amends, or will be deemed to amend (or prevent the amendment or termination of) any Partnership Employee Benefit Plan or any Parent Employee Benefit Plan. Parent has no obligation to continue to employ or retain the services of any Continuing Employee for any period of time following the Effective Time and, except as specifically provided in this Section 7.15, Parent will be entitled to modify any compensation or benefits provided to, and any other terms or conditions of employment of, any such employees in its absolute discretion.

7.16 Transaction Litigation. The Partnership shall give Parent the opportunity to participate in the defense or settlement of any security holder litigation against the Partnership, the Partnership GP and/or its respective directors relating to the Merger and the other transactions contemplated by this Agreement, and no such settlement shall be agreed to without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed.

7.17 Financing Cooperation. Prior to the Effective Time, the Partnership Entities shall, and shall cause their respective Subsidiaries and their respective Representatives to, at Parent’s sole cost and expense, provide all cooperation that is reasonably necessary, proper or advisable in connection with any financing by Parent or any of its Subsidiaries in connection with the Merger as may be reasonably requested by Parent or its Representatives. Without limiting the generality of the foregoing, the Partnership Entities shall, and shall cause their respective Subsidiaries and use commercially reasonable efforts to cause their respective Representatives to (i) furnish, as promptly as practicable, the report of the Company’s auditor on the most recently available audited consolidated financial statements of the Company and its Subsidiaries and use its commercially reasonable efforts to obtain the consent of such auditor to the use of such report in accordance with normal custom and practice and use commercially reasonable efforts to cause such auditor to provide customary comfort letters (providing “negative assurance” comfort) and drafts thereof to the underwriters, initial purchasers or placement agents, as applicable, in connection with such financing by Parent; (ii) use commercially reasonable efforts to furnish, as promptly as practicable, financial statements and other financial data of the Partnership as would be required by Regulation S-X and Regulation S-K promulgated under the Securities Act for a registered public offering to consummate any offering(s) of securities contemplated by such financing; and (iii) provide reasonable and customary assistance in the preparation of one or more confidential information memoranda, prospectuses, offering memoranda, private placement memoranda and other marketing and syndication materials (including the provision of authorization letters and a representation with respect to the presence or absence of material non-public information) reasonably requested by Parent, including by making available, at reasonable times and on reasonable advance notice, employees and advisors of the Partnership Entities; provided that (x) none of the Partnership or any of its Subsidiaries shall be required to pay any commitment or other fee or incur any other liability or obligation in connection with such financing or to take any action that would be prohibited by any applicable Law or cause a default of, or breach under, or otherwise violate any Partnership Material Agreement, in each case except for any payment, incurrence or action that is conditioned upon, and shall not take effect until, the Effective Time, (y) no obligations of the Partnership or any of its Subsidiaries under any certificate, opinion, contract, indenture or other document or instrument delivered pursuant to this Section 7.17 shall be effective until the Effective Time, and none of the Partnership or any of its Subsidiaries shall be required to take any action pursuant to this Section 7.17 under any certificate, opinion, contract, indenture or other document or instrument that is not contingent upon the Closing or that would be effective

prior to the Effective Time and (z) none of the Partnership or its senior officers shall be required to engage in any action that would interfere unreasonably with the business of the Partnership and its Subsidiaries. Parent shall indemnify and hold harmless the Partnership and its Subsidiaries and their respective officers, directors and other Representatives from and against any and all losses or damages suffered or incurred by them in connection with the arrangement of any financing by Parent or any of its Subsidiaries in connection with the Merger and any information utilized in connection therewith except (A) with respect to information supplied by the Partnership, its Subsidiaries and Representatives specifically for inclusion or incorporation by reference therein and/or (B) to the extent such losses and damages arise from the willful misconduct of the Partnership or any of its Subsidiaries’ officers, directors, employees or Representatives.

7.18 Parent Distributions. Subject to the Parent Partnership Agreement and Delaware law, effective as of the first full calendar month following the Effective Time, Parent shall increase its monthly distributions to the holders of Parent Common Units to at least $0.1733 per Parent Common Unit per month.

7.19 Director Appointment. Prior to the Closing, Parent shall take all action necessary to increase the size of the Parent Board by one, and elect as a member of the Parent Board effective as of the Effective Time one individual mutually agreed by Parent and the Partnership prior to Closing, with such person to hold office in accordance with the Parent Partnership Agreement.

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

(b) by the Partnership or Parent if there is in effect a final nonappealable order of a Governmental Authority of competent jurisdiction restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; provided, that the right to terminate this Agreement under this Section 9.1(b) is not available to the Partnership, on the one hand, or Parent, on the other hand, if such order was primarily due to the failure of the Partnership, on the one hand, or any of Parent or Merger Sub, on the other hand, to perform any of its obligations under this Agreement;

(c) by Parent if (i) the Partnership has breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or (ii) any representation or warranty of the Partnership becomes untrue, and, with respect to either clause (i) or (ii) above, which breach, failure to perform or untruth if it was continuing as of the Closing Date would result in the failure of the conditions set forth in Sections 8.3(a) or (b) to be satisfied and such breach, failure to perform or untruth is incapable of being cured (or become true) or, if capable of being cured (or become true), is not cured (or become true) by the earlier of (x) the Outside Date or (y) within 30 days following receipt by the Partnership of notice of such breach, failure or untruth from Parent;

(d) by the Partnership if (i) Parent has breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or (ii) any representation or warranty of Parent becomes untrue, and, with respect to either clause (i) or (ii) above, which breach, failure to perform or untruth if it was continuing as of the Closing Date

would result in the failure of the conditions set forth in Sections 8.2(a) or (b) to be satisfied and such breach, failure to perform or untruth is incapable of being cured (or become true) or, if capable of being cured (or become true), is not cured (or become true) by the earlier of (x) the Outside Date or (y) within 30 days following receipt by Parent of notice of such breach, failure or untruth from the Partnership;

(e) by the Partnership or Parent if the Closing does not occur on or before March 31, 2015 (the “Outside Date”); provided, however, that such failure of the Closing to occur is not due to the failure of such Party to perform and comply in all material respects with the covenants and agreements to be performed or complied with by such Party prior to the Closing;

(f) by the Partnership or Parent if the Partnership Meeting has concluded and the Partnership Unitholder Approval has not been obtained;

(g) by Parent, if a Partnership Change in Recommendation has occurred; or

9.3 Effect of Termination. In the event that this Agreement is validly terminated as provided in Section 9.1, then each of the Parties will be relieved of its duties and obligations arising under this Agreement after the date of such termination and such termination will be without liability to Parent or the Partnership; provided, that the agreements and obligations of the Parties set forth in Section 7.6, this Section 9.3, Section 9.4 and Article X hereof will survive any such termination and are enforceable hereunder; provided further, that nothing in this Section 9.3 relieves any of Parent or the Partnership of any liability for fraud or any Willful Breach of any covenant or agreement contained herein occurring prior to termination, or as provided in the Confidentiality Agreement, in which case the aggrieved party shall be entitled to all rights and remedies available at law or in equity (including, in the case of the Parent, liability for damages based on the consideration that would have otherwise been payable to the holders of Partnership Units). “Willful Breach” means an intentional and willful material breach, or an intentional and willful material failure to perform, in each case that is the consequence of an act or omission by a Party with the knowledge that the taking of, or failure to take, such act would, or would be reasonably expected to, cause a material breach of this Agreement.

(a) In the event that (i) an Alternative Proposal is publicly submitted, publicly proposed or publicly disclosed prior to, and not withdrawn at the time of, the date of the

Partnership Meeting (or, if the Partnership Meeting has not occurred, prior to the termination of this Agreement pursuant to Section 9.1(e)) and (ii) this Agreement is terminated by the Partnership or Parent pursuant to Section 9.1(c), Section 9.1(e) or Section 9.1(f) and (iii) the Partnership enters into a definitive agreement with respect to, or consummates, an Alternative Proposal within twelve months after the date this Agreement is terminated, then the Partnership will pay to Parent the Termination Fee minus the Expenses previously paid or reimbursed by the Partnership, upon the earlier of the public announcement that the Partnership has entered into such definitive agreement or the consummation of any such transaction.

(b) In the event this Agreement is terminated (i) by Parent pursuant to Section 9.1(c) or (ii) by the Partnership pursuant to Section 9.1(d), in each of cases (i) and (ii), the non-terminating party will pay the terminating party, within two Business Days after the date of termination, the Expenses.

(c) In the event this Agreement is terminated by (i) Parent pursuant to Section 9.1(g), then the Partnership will pay to Parent, within two Business Days after the date of termination, the Termination Fee or (ii) the Partnership pursuant to Section 9.1(h), then the Partnership will immediately prior to or simultaneously with such termination pay to Parent, the Termination Fee.

(d) Any payment of the Termination Fee or Expenses (or applicable portion thereof) will be made in cash by wire transfer of same day funds to an account designated in writing by the recipient of such payment.

(e) The Partnership acknowledges that the provisions of this Section 9.4 are an integral part of the transactions contemplated hereby and that, without these agreements, Parent would not enter into this Agreement. The parties agree that in the event that the Partnership pays the Termination Fee to Parent, the Partnership has no further liability to Parent of any kind in respect of this Agreement and the transactions contemplated hereby.

(f) As used herein, (i) “Termination Fee” means a cash amount equal to $64,875,000, and (ii) “Expenses” means the reasonable and documented out-of-pocket expenses of a party incurred in connection with the negotiation, execution and delivery of this Agreement and the performance of the transactions contemplated hereby up to an aggregate amount equal to $16,425,000. In no event will the Partnership or the Parent be required to pay the other Party’s Expenses on more than one occasion.

(g) In no event shall Parent be entitled to more than one payment of the Termination Fee in connection with this Agreement pursuant to which the Termination Fee is payable, and if the Termination Fee is payable at such time as Parent has already received payment or concurrently receives payment from the Partnership in respect of Parent’s Expenses, the amount of such Expenses actually received by Parent shall be deducted from the Termination Fee.

(h) Except as otherwise provided in this Agreement, including in this Section 9.4, each party shall pay its own expenses incident to preparing for, entering into and carrying out this Agreement and the consummation of the transactions contemplated by this Agreement; provided, that Parent and the Partnership shall each bear and pay one-half of (i) the fees payable in connection with the filings required to be made under the HSR Act and (ii) the expenses incurred in connection with the filing, printing and mailing of the Registration Statement and Proxy Statement.

(i) Each of the Parties acknowledges that the agreements contained in this Section 9.4 are an integral part of the transactions contemplated hereby, and that, without these agreements, the Parties would not enter into this Agreement.

Any purported assignment not permitted under this Section 10.5 shall be null and void.

10.6 Entire Understanding; No Third-Party Beneficiaries. This Agreement together with the Registration Rights Agreement, the Lock-up Agreement and the Confidentiality Agreement constitute the entire agreement and understanding of the Parties with respect to the matters therein and supersedes all prior agreements and understandings on such matters. The provisions of this Agreement are binding upon, inure to the benefit of the Parties and, subject to Section 10.5, their respective successors and assigns, and no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the Parties and their respective successors and, except (a) as provided in Section 7.10 (which will be to the benefit of and enforceable by the Persons referred to in such Section), (b) following the Effective Time, the rights of holders of Partnership Common Units and Partnership Class B Units to receive the Merger Consideration and the right of the holders of Partnership Class C Units to receive the Cash Consideration and (c) as provided in Section 10.13 (which will be to the benefit of and enforceable by the Financing Sources).

10.7 Severability. Any provision of this Agreement which is invalid, illegal or unenforceable in any jurisdiction will, as to that jurisdiction, be ineffective only to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions hereof in such jurisdiction or rendering that or any other provision of this Agreement invalid, illegal or unenforceable in any other jurisdiction.

10.8 Jurisdiction.

(a) Each of the Parties irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder shall be brought and determined exclusively in the Court of Chancery of the State of Delaware or, if such Court does not have subject matter jurisdiction, to the Superior Court of the State of Delaware or, if jurisdiction is vested exclusively in the Federal courts of the United States, the Federal courts of the United States sitting in the State of Delaware, and any appellate court from any such state or Federal court, and hereby irrevocably and unconditionally agree that all claims with respect to any such claim shall be heard and determined in such Delaware court or in such Federal court, as applicable. The Parties agree that a final judgment in any such claim is conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by law.

(b) Each of the Parties irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any related matter in any Delaware state or Federal court located in the State of Delaware and the defense of an inconvenient forum to the maintenance of such claim in any such court.

(c) Each of the Parties agrees that it will not, and it will not permit any of its controlled Affiliates to, bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind of description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source or any Financing Related Party, in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or relating in any way to the financing or the performance thereof, in any forum other than the U.S. District Court for the Southern District of New York or, if such court does not have subject matter jurisdiction, in any state court located in the Borough of Manhattan (and the Parties hereto agree to submit to the exclusive jurisdiction of, and venue in, such court in connection therewith), and that the provisions Section 10.9 relating to waiver of jury trial shall apply to such action, cause of action, claim, cross-claim or third-party claim.

10.9 Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY HEREBY IRREVOCABLY WAIVES AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING IN WHOLE OR IN PART UNDER, RELATED TO, BASED ON, OR IN CONNECTION WITH, THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN TORT OR CONTRACT OR OTHERWISE. ANY PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 10.9 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

10.10 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 past, present or future Affiliate, director, officer, employee, incorporator, member, manager, partner, stockholder, agent, attorney or representative of any Party has any liability for any obligations or liabilities of the Parties or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.

10.11 Specific Performance. The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 10.11 in the Delaware Court of Chancery or any state or federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (x) any Party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each Party further agrees that no Party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 10.11, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

10.12 Survival. Except as otherwise provided in this Agreement, none of the representations, warranties, agreements and covenants contained in this Agreement will survive the Closing or the termination of this Agreement if this Agreement is validly terminated in accordance with Article IX prior to the Closing; provided, however, that if the Closing occurs, the agreements of the Parties in Sections 3.2, 3.3, 3.4, 3.5, 7.10, 7.15, 7.16, 7.18 and Article X will survive the Closing, and if this Agreement is terminated prior to the Closing, the agreements of the Parties in Sections 7.6, 9.2, 9.3 and 9.4, and this Article X will survive such termination. The Confidentiality Agreement shall (i) survive termination of this Agreement in accordance with its terms and (ii) terminate as of the Effective Time.

10.13 No Recourse to Financing Sources. Notwithstanding anything herein to the contrary, the Partnership Entities agree, on behalf of themselves and each of their former, current or future officers, directors, managers, employees, members, partners, Partnership Unitholders, agents and other representatives and controlled Affiliates (the “Partnership Parties”) that Parent’s, Parent GP’s and Merger Sub’s financial institutions and their respective Affiliates (collectively “Financing Sources”), and each of their respective former, current or future general or limited partners, stockholders, managers, members, agents, representatives and Affiliates, and each of their successors and assigns (collectively, “Finance Related Parties”) shall be subject to no liability or claims to the Partnership Parties in connection with the financing of or in any way relating to this Agreement or any of the transactions contemplated hereby or thereby, whether at law, in equity, in contract, in tort or otherwise. Notwithstanding anything to the contrary in this Agreement, (a) no amendment or modification to Section 10.6(c), Section 10.8(c) or this Section 10.13 (or amendment or modification with respect to any related definitions as they affect the second paragraph of Section 10.6(c), Section 10.8(c) or this Section 10.13) shall be effective without the prior written consent of each Financing Source (on behalf of themselves and the applicable Financing Related Parties), (b) no amendment or modification to Section 9.4 (or any amendment or modification with respect to any related definitions as they affect Section 9.4) that would be adverse to the Financing Sources or the Financing Related Parties shall be effective without the prior written consent of each Financing Source (on behalf of themselves and the applicable Financing Related Parties), and (c) each Financing Source and Financing Related Party shall be an express third party beneficiary of, and shall have the right to enforce, the second paragraph of Section 10.6(c), Section 10.8(c) or this Section 10.13. Each of the Parties hereto agrees that Section 10.3 notwithstanding, this Section 10.13 shall be interpreted and any action relating to this provision shall be governed by the laws of the State of New York.
