Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place remotely by exchange of documents and signatures (or their electronic counterparts) at 9:00 a.m., Central time on the second business day after the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other place, date and time as the Partnership and Parent may agree in writing. The date on which the Closing actually occurs is referred to as the “Closing Date.”

Section 1.3 Effective Time. At the Closing, the Partnership shall file with the Secretary of State of the State of Delaware a certificate of merger (the “Certificate of Merger”), executed in accordance with, and containing such information as is required by, the relevant provisions of the Delaware LP Act, the Delaware LLC Act and the Existing Partnership Agreement in order to effect the Merger, and make any other filings or recordings as may be required by Delaware law in

Section 1.4 Effects of the Merger. The effects of the Merger shall be as provided in this Agreement and in the applicable provisions of the Delaware LP Act, the Delaware LLC Act and Section 14.5 of the Existing Partnership Agreement. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the rights, privileges and powers, and all property, real, personal and mixed, and all debts due to either of the Partnership or Merger Sub, as well as all other things and causes of action belonging to each of the Partnership and Merger Sub, shall vest in the Surviving Entity without further act or deed, all as provided under the Delaware LP Act, the Delaware LLC Act and Section 14.5 of the Existing Partnership Agreement.

Section 1.5 Organizational Documents of the Surviving Entity. At the Effective Time, (a) the Partnership’s Certificate of Limited Partnership as in effect immediately prior to the Effective Time shall remain unchanged and shall be the certificate of formation of the Surviving Entity from and after the Effective Time, until duly amended in accordance with the provisions thereof and applicable Law, and (b) the Partnership’s limited partnership agreement as in effect immediately prior to the Effective Time shall remain unchanged and shall be the limited partnership agreement of the Surviving Entity from and after the Effective Time, until duly amended in accordance with the provisions thereof and applicable Law.

Section 1.6 Partnership Managing GP Directors. At the Effective Time, the persons listed on Section 1.6 of the Parent Disclosure Schedule shall be appointed as the directors of the Partnership Managing GP and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal in accordance with the terms of the limited liability company agreement of Partnership Managing GP.

Section 1.7 Partnership Managing GP Officers. The officers of Merger Sub immediately prior to the Effective Time shall be appointed as the officers of Partnership Managing GP and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal in accordance with the terms of the limited liability company agreement of Partnership Managing GP.

Section 1.8 Parent GP Director. Prior to the Effective Time, Parent and the Parent GP shall take all necessary action so that upon and after the Effective Time the size of the current Parent GP Board is increased by one (1) member and, effective as of the Effective Time, a member of the Partnership Managing GP Board to be mutually agreed between Parent and the Partnership (the “New Parent Director”) is appointed to the Parent GP Board to fill the vacancy on the Parent GP Board created by such increase. So long as the New Parent Director continues to satisfy any requirements of applicable Laws and regulations (including of the NYSE) and corporate governance polices of ET applicable to serving as a member of the Parent GP Board applicable to all members of the Board, in their capacities as such, and complies with the provisions of the Parent Partnership Agreement and the Parent GP LLC Agreement applicable to all members of the Parent GP Board in their capacities as such, the Parent GP and Parent shall not, and shall cause their

respective controlled affiliates and use reasonable best efforts to cause their respective other affiliates to not, take any action to remove the New Parent Director from the Parent GP Board (or otherwise take or refrain from taking any action having the effect of the New Parent Director not serving as a member of the Parent GP Board) for a period of one (1) year following the Effective Time.

ARTICLE II

CONVERSION OF UNITS; EXCHANGE OF CERTIFICATES; EQUITY AWARDS

Section 2.1 Conversion of Partnership Interests. Subject to the terms and conditions of this Agreement, at the Effective Time, and by virtue of the Merger and without any action on the part of Parent, the Parent GP, Merger Sub, the Partnership, Partnership GP or Partnership Managing GP or any of their respective affiliates or any holder of securities of Parent, the Parent GP, Merger Sub, the Partnership, Partnership GP or Partnership Managing GP:

(a) Each Partnership Common Unit issued and outstanding immediately prior to the Effective Time (other than any Excluded Units and Parent Subsidiary Held Units) shall be converted into and shall thereafter represent the right to receive 0.400 (the “Exchange Ratio”) common units representing limited partner interests in Parent having the rights and obligations specified with respect to “Common Units” in the Parent Partnership Agreement (the “Parent Common Units” and such consideration, the “Merger Consideration”). Each person that receives Parent Common Units upon the exchange of Partnership Common Units for the Merger Consideration in accordance with this Article II shall be admitted as a limited partner of Parent.

(b) Each Partnership Preferred Unit issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding from and after the Effective Time as limited partnership interests of the Surviving Entity in the Merger having the same terms as are applicable to the Partnership Preferred Units immediately prior to the Effective Time.

(c) The general partner interest in the Partnership issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding from and after the Effective Time as the general partner interest of the Surviving Entity in the Merger.

(d) Notwithstanding anything to the contrary in this Agreement, at the Effective Time, (i) all Partnership Common Units directly owned immediately prior to the Effective Time by the Partnership or by Parent or Merger Sub (collectively, the “Excluded Units”) and (ii) any Partnership Common Units owned, immediately prior to the Effective Time, by a Subsidiary of Parent (including any New Parent Subsidiary Units) (“Parent Subsidiary Held Units”) shall remain issued and outstanding from and after the Effective Time as limited partnership interests of the Surviving Entity in the Merger having the same terms as are applicable to Partnership Common Units immediately prior to the Effective Time.

Section 2.2 Rights as Unitholders; Unit Transfers.

(a) All Partnership Common Units converted into the right to receive the Merger Consideration pursuant to Section 2.1(a) 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 (a “Certificate”) and each holder of non-certificated Partnership Common Units represented in book-entry form (“Book-Entry Units”) will cease to be a limited partner of the Partnership in their capacity as a holder of Partnership Common Units and cease to have any rights with respect thereto, except the right to receive (i) the Merger Consideration, (ii) any cash to be paid in lieu of any fractional Parent Common Units in accordance with Section 2.4(d) and (iii) any distributions in accordance with Section 2.4(c) and this Section 2.2(a); provided, however, that the rights of (x) any holder of the Partnership LTI Awards shall be as set forth in Section 2.6, and (y) Parent, the Partnership and their respective Subsidiaries will be as set forth in Section 2.1(d). In addition, holders as of the relevant record date of Partnership Common Units outstanding immediately prior to the Effective Time will have continued rights to any distribution, without interest, with respect to such Partnership Common 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 Partnership Common 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, and will be paid by Parent on the payment date set therefor to such holders as of the relevant record date of Partnership Common Units, whether or not they exchange their Partnership Common Units pursuant to Section 2.4.

(b) At the Effective Time, there will be no further registration of transfers on the unit transfer books of the Partnership with respect to Partnership Common Units and, promptly following the Effective Time, the books and records of the Partnership will be revised to reflect that Parent will be admitted as a limited partner of the Partnership.

Section 2.3 Merger Sub Interests. At the Effective Time, and by virtue of the Merger and without any action on the part of any person, each limited liability company interest of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into a number of validly issued, fully paid (to the extent required by the Existing Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act) Partnership Common Units, equal in number to the number of Partnership Common Units outstanding as of immediately prior to the Effective Time (other than Parent Subsidiary Held Units, if any) and, together with any outstanding Partnership Preferred Units and Parent Subsidiary Held Units, if any, outstanding immediately after the Effective Time in accordance with Section 2.1(b), shall constitute the only outstanding limited partnership interests of the Surviving Entity as of immediately after the Effective Time.

Section 2.4 Exchange of Partnership Common Units.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint an exchange agent mutually and reasonably acceptable to Parent and the Partnership (the “Exchange Agent”) in connection with the Merger and in connection therewith, shall enter into an agreement with the Exchange Agent in a form reasonably acceptable to the Partnership (the “Exchange Agent Agreement”). At or prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, in trust for the benefit of holders of Partnership Common Units (other than the Excluded Units), Parent Common Units (which shall be in non-certificated book-entry form) issuable pursuant to Section 2.1(a) and Section 2.6 and an amount of cash sufficient to effect delivery of cash lieu of any fractional Parent Common Units in accordance with Section 2.4(d). Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, Parent Common Units issuable and cash required to effect delivery of cash lieu of any fractional Parent Common Units in accordance with Section 2.4(d), make any Regular Distribution in accordance with Section 2.2 and make any distributions in accordance with Section 2.4(c) (all Parent Common Units and cash deposited with the Exchange Agent from time to time, the “Exchange Fund”). The Exchange Fund shall not be used for any purpose that is not expressly provided for in this Agreement.

(b) Exchange Procedures.

(i) Promptly after the Effective Time (and after receipt by the Exchange Agent of all information reasonably necessary to enable the Exchange Agent to effect the mailing set forth in this Section 2.4(b); provided, however, that Parent and the Surviving Entity shall use reasonable best efforts to obtain such information to enable such mailing to occur no later than the third business day following the Effective Time), Parent or the Surviving Entity shall cause the Exchange Agent to mail to each record holder of Partnership Common Units as of immediately prior to the Effective Time (other than the holders of Excluded Units), (A) a letter of transmittal in customary form and agreed to by Parent and the Partnership prior to the Effective Time that will specify that, in respect of certificated Partnership Common Units, delivery will be effected, and that risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Exchange Agent (including by delivery of the Partnership Common Units, book-entry notation, or affidavits of loss in lieu of delivery thereof as provided in Section 2.4(g)) (the “Letter of Transmittal”) to the Exchange Agent and (B) 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, cash in lieu of any fractional Parent Common Units in accordance with Section 2.4(d), any Regular Distribution in accordance with Section 2.2 or any distributions in accordance with Section 2.4(c).

(ii) Upon surrender of Certificates or Book-Entry Units, if any, for cancellation to the Exchange Agent, together with 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, each holder who held Partnership Common Units immediately prior to the Effective Time (other than the holders of Excluded Units) will be entitled to receive in exchange therefor the Merger Consideration (after taking into account all Partnership Common Units surrendered by such holder and subject to any withholding tax

specified in Section 2.5) and an aggregate amount of cash that such holder has the right to receive with respect to such Partnership Common Units pursuant to Section 2.2, Section 2.4(c) and Section 2.4(d). No interest will be paid or accrued on any distributions in accordance with Section 2.2 or Section 2.4(c) or any cash payment in lieu of fractional Parent Common Units in accordance with Section 2.4(d). In the event of a transfer of ownership of Partnership Common Units that is not registered in the transfer records of the Partnership, the Merger Consideration, any distributions in accordance with Section 2.2 or Section 2.4(c) and any cash to be paid in lieu of any fractional Parent Common Units in accordance with Section 2.4(d) in respect of such Partnership Common Units may be paid to a transferee, if the Certificate representing such Partnership Common Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both Certificates and Book-Entry Units, accompanied by all documents reasonably required to evidence and effect such transfer, and that the person requesting such exchange will pay to the Exchange Agent any transfer or other similar Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such Partnership Common Units, or will establish to the reasonable satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until such required documentation has been delivered and Certificates and Book-Entry Units, if any, have been surrendered, as contemplated by this Section 2.4, 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 in respect of Partnership Common Units, any cash or distributions to which such holder is entitled pursuant to Section 2.4(c) and Section 2.4(d) and (without the necessity of such surrender) any Regular Distribution in accordance with Section 2.2.

(c) Parent Distributions with Respect to Unexchanged Partnership Common 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 unsurrendered Partnership Common Units and no cash payment in lieu of fractional Parent Common Units will be paid to any such holder, in each case, until such holder has delivered the required documentation and surrendered any such Certificates or Book-Entry Units as contemplated by this Section 2.4. Subject to applicable Law and Section 5.18, following compliance with the requirements of Section 2.4(b), there will be paid to the holder of Parent Common Units, without interest, (i) promptly after the time of such compliance, and with no effect to the Merger Consideration to which such holder is entitled to pursuant to Section 2.1(a) (after taking into account all Partnership Common Units surrendered by such holder and subject to any withholding tax specified in Section 2.5), the amount of any cash payable in lieu of fractional Parent Common Units to which such holder is entitled pursuant to Section 2.4(d) and the amount of distributions with a record date after the Effective Time theretofore paid with respect to such Parent Common Units, and (ii) at the appropriate payment date, the amount of distributions with a record date after the Effective Time but prior to such delivery and surrender of Partnership Common Units and a payment date subsequent to such delivery and surrender payable with respect to such Parent Common Units.

(d) Fractional Units. No fractional Parent Common Units shall be issued in the Merger, but in lieu thereof each holder of Partnership Common Units otherwise entitled to a fractional Parent Common Unit will be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 2.4(d), a cash payment (without interest and rounded to the nearest cent) in lieu of such fractional Parent Common Unit in an amount equal to the product of

(i) the volume-weighted average closing price of one Parent Common Unit as reported on the NYSE for the ten consecutive full trading days ending at the close of trading on the full trading day immediately preceding the Closing Date (the “Parent Trading Price”) and (ii) the fraction of a Parent Common Unit that such holder would otherwise be entitled to receive pursuant to this Article II. No certificates or scrip representing fractional Parent Common Units shall be issued in the Merger. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Partnership Common Units in lieu of any fractional Parent Common Units, Parent will cause the Exchange Agent to make available such amounts to such holders of Partnership Common Units, without interest, subject to and in accordance with Section 2.4. The parties acknowledge that payment of cash in lieu of issuing fractional Parent Common Units was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of complying with the Parent Partnership Agreement and avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance of fractional Parent Common Units.

(e) No Further Ownership Rights in Partnership Common Units. The Merger Consideration issued upon conversion of a Partnership Common Unit in accordance with the terms hereof, together with any cash in lieu of fractional Parent Common Units to be paid in accordance with Section 2.4(d) and any declared distributions to be paid on Parent Units as described in Section 2.4(c), will be deemed to have been issued (or paid) in full satisfaction of all rights pertaining to such Partnership Common Unit (other than the right to receive any Regular Distribution in accordance with Section 2.2). If, after the Effective Time, Certificates are presented to the Surviving Entity or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Section 2.4(e).

(f) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Partnership Common Units for eighteen (18) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Partnership Common Units who have not theretofore complied with this Section 2.4 shall thereafter look only to Parent for payment of their claim for the Merger Consideration, any cash in lieu of fractional Parent Common Units in accordance with Section 2.4(d) and any distributions pursuant to Section 2.4(c). Any amounts remaining unclaimed by holders of Partnership Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any Governmental Authority will, to the extent permitted by applicable Law, become the property of Parent.

(g) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration and distributions to be paid in respect of the Partnership Common Units represented by such Certificate as contemplated by this Section 2.4(g).

(h) No Liability. Notwithstanding anything in this Agreement to the contrary, none of the Partnership, Parent, Merger Sub, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of Partnership Common Units for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 2.5 Withholding. Each of Parent, the Partnership, Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as Parent, the Partnership, Merger Sub or the Exchange Agent, as applicable, is required to deduct and withhold under the Internal Revenue Code of 1986, as amended (the “Code”), or any Tax Law, with respect to the making of such payment; provided that, each of Parent and Merger Sub shall use reasonable best efforts to cooperate with any reasonable request of the Partnership in order to reduce or eliminate any such deduction or withholding. To the extent that amounts are so deducted and withheld and timely paid over to the applicable Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. If any such deduction or withholding is taken in Parent Units, Parent, Merger Sub or the Exchange Agent (as applicable) shall be treated as having sold such Parent Units on behalf of the applicable recipient for an amount of cash equal to the fair market value of such Parent Units at the time of such deemed sale.

(iii) With respect to each Partnership Time-Vesting Cash Award, an amount in cash equal to one hundred percent (100%) of the amount of cash subject to such Partnership Time-Vesting Cash Award.

(b) Any amounts payable pursuant to Partnership LTI Awards that vest as of the Effective Time pursuant to Section 2.6(a) shall be paid as soon as practicable following the Effective Time, but no later than the Surviving Entity’s next regularly scheduled payroll date, net of applicable Tax withholding.

(c) With respect to the Nustar Services Company LLC Employee Unit Purchase Program (the “Purchase Program”), the Partnership and the Partnership Subsidiaries shall take all actions reasonably necessary to provide that (i) no individual who is not participating in the Purchase Program as of the date of this Agreement may commence participation in the Purchase Program and (ii) the Purchase Program shall terminate no later than fifteen (15) days prior to the Effective Time.

(i) in response to an Acquisition Proposal, only if: (A) none of the Partnership, Partnership GP or the Partnership Managing GP shall have Willfully Breached any of the provisions set forth in this Section 5.4 (it being understood that, for purposes of this clause, any action by the Partnership Subsidiaries or by a Representative of the Partnership or the Partnership Subsidiaries that, if taken by Partnership, Partnership GP or the Partnership Managing GP would constitute a Willful Breach of this Section 5.4 shall constitute a Willful Breach by the Partnership, Partnership GP and Partnership Managing GP) which Willful Breach was a material contributing factor to the making of the applicable Acquisition Proposal; (B) the Partnership Managing GP Board determines in good faith, after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes a Superior Proposal; (C) following such determination, the Partnership provides to Parent written notice (“Notice of Change”) to the effect that the Partnership Managing GP Board has determined in good faith, after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes a Superior Proposal and advising Parent that the Partnership Managing GP Board proposes to effect a Change of Recommendation absent any change to the terms and conditions of this Agreement; (D) during the period from the time the Notice of Change is provided until 5:00 p.m., Central time, on the third business day immediately following the day on which the Partnership delivered the Notice of Change (such period, the “Notice of Change Period”) (it being understood and agreed that each material revision, amendment, update or supplement to the terms and conditions of such Superior Proposal, including any revision in price of financing, in each case during such three (3) business day period shall require a new written notice by the Partnership to Parent of any such material revision, amendment, update or supplement to the terms and conditions of such Superior Proposal, and such three (3) business day period shall be extended until the second (2nd) business day from the date of receipt of such additional notice by Parent), if requested by Parent, the Partnership and its Representatives use reasonable best efforts to engage in good faith negotiations with Parent and its Representatives, the intent and purpose of which is to amend this Agreement in such a manner that obviates the need for such Change of Recommendation or termination of this Agreement; and (E) at the end of such Notice of Change Period, such Acquisition Proposal has not been withdrawn, and the Partnership Managing GP Board reaffirms in good faith after consultation with its financial advisor and outside legal counsel that such Acquisition Proposal continues to constitute a Superior Proposal (taking into account any changes to the terms of this Agreement proposed by Parent as a result of the negotiations required by clause (D) or otherwise); or

(ii) in response to an Intervening Event, only if: (A) the Partnership Managing GP Board determines in good faith, after consultation with its financial advisor and outside legal counsel, to effect a Change of Recommendation absent any revision to the terms and conditions of this Agreement; (B) following such meeting, the Partnership provides to Parent written notice (a “Notice of Intervening Event”) to the effect that the Partnership Managing GP Board has determined in good faith, after consultation with its financial advisor and outside legal counsel, that the Partnership Managing GP Board proposes to effect a Change of Recommendation absent any revision to the terms and conditions of this Agreement; (C) during the period from the time the Notice of Intervening Event is provided until 5:00 p.m., Central time, on the third business day immediately following the day on which the Partnership delivered the Notice of Intervening Event (such period, the “Notice of Intervening Event Period”) (it being understood and agreed that each material development with respect to an Intervening Event during such three (3) business day period shall require a new written notice by the Partnership to Parent of any such material development, and such three (3) business day period shall be extended until the second (2nd) business day from the date of receipt of such additional notice by Parent), if requested by Parent, the Partnership and its Representatives have engaged in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need for such Change of Recommendation; (D) the Partnership Managing GP Board has considered in good faith any revisions to the terms of this this Agreement proposed by Parent as a result of the negotiations contemplated by clause (C) or otherwise and (E) the Partnership Managing GP Board determines in good faith (taking into account any changes to the terms of this Agreement proposed by Parent as a result of the negotiations contemplated by clause (C) or otherwise), after consultation with its financial advisor and outside legal counsel, that the failure to make such a Change of Recommendation in response to such Intervening Event would be inconsistent with the directors’ duties under applicable Law and the Existing Partnership Agreement.

(f) Nothing in this Agreement shall prevent the Partnership Managing GP Board from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 and Rule 14e-2 or Item 1012(a) of Regulation M-A under the Exchange Act or (ii) making any “stop-look-and-listen” communication or similar communication of the type contemplated pursuant to Rule 14d-9 under the Exchange Act; provided, however, that any such disclosure or communication in each of clause (i) or (ii) shall not by themselves constitute or be deemed to be a Change of Recommendation.

(g) As used in this Agreement:

(i) “Acceptable Confidentiality Agreement” means a confidentiality agreement to which the Partnership is a party, the material provisions of which, as they relate to confidentiality, are no less favorable in the aggregate to the Partnership than those contained in the Confidentiality Agreement; provided, however, that such confidentiality agreement shall not restrict compliance by the Partnership with the terms of this Section 5.4. For the avoidance of doubt, a joinder to an Acceptable Confidentiality Agreement pursuant to which a Third Party agrees to be bound by the confidentiality and use provisions of an Acceptable Confidentiality Agreement shall be an Acceptable Confidentiality Agreement;

(iv) “Intervening Event” means any material event, fact, circumstance, development or occurrence that is not known or reasonably foreseeable (or if known or reasonably foreseeable, the material consequences of which were not known or reasonably foreseeable), to or by the Partnership Managing GP Board as of the entry into this Agreement, which event, fact, circumstance, development, occurrence or material consequences becomes known to or by the Partnership Managing GP Board prior to obtaining the Partnership Unitholder Approval; provided, however, that such event, fact, circumstance, development or occurrence shall not constitute an Intervening Event if such event, fact, circumstance, development or occurrence results from or arises out of: (A) any changes in the unit price or trading volume of the Partnership Units or Parent Common Units or in the credit rating of Parent or the Partnership or any their respective Subsidiaries (provided, however, that the exception in this clause (A) shall not prevent or otherwise affect a determination that any event, change, effect, development or occurrence underlying such change has resulted in an Intervening Event), (B) any Acquisition Proposal or (C) any Superior Proposal;

(v) “Superior Proposal” means a written Acquisition Proposal (with references in the definition of Acquisition Transaction contained in the definition of Acquisition Proposal to “20%” being deemed to be replaced with references to “50%”) that the Partnership Managing GP Board, or any committee thereof, determines, in good faith, after consultation with its outside legal counsel and its financial advisor, is (A) if accepted, reasonably likely to be consummated (or, alternatively, at least as likely as the Merger to be consummated), and (B) more favorable, from a financial point of view, to the holders of Partnership Common Units than the Merger and the transactions contemplated by this Agreement, after taking into account all factors that the Partnership Managing GP Board determined are relevant acting in a manner consistent with their duties under applicable Law and the Existing Partnership Agreement; and

(vi) “Third Party” means any person, including any “group” as defined in Section 13(d) of the Exchange Act, other than Parent or any of its affiliates or any “group” that includes Parent or any of its affiliates (it being understood and acknowledged, for the avoidance of doubt, ET and its affiliates shall not be a Third Party hereunder).

Subject to Section 5.4, the Partnership shall include the Partnership Recommendation in the Proxy Statement/Prospectus. Each of Parent and the Partnership shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective for so long as necessary to consummate the Merger and the transactions contemplated hereby. The Partnership will use reasonable best efforts to cause the Proxy Statement/Prospectus to be mailed to the holders of Partnership Common Units as soon as reasonably practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action required to be taken under any applicable state securities laws in connection with the issuance and reservation of Parent Common Units in the Merger, and the Partnership shall furnish all information concerning the Partnership and the holders of Partnership Common Units and Partnership Preferred Units, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement/Prospectus will be made by Parent or the Partnership, as applicable, without providing the other party a reasonable opportunity to review and comment thereon.

(b) Parent or the Partnership, as applicable, will advise the other promptly after the receipt of any comments of the staff of the SEC with respect to the Form S-4 or the Proxy Statement/Prospectus and of any request by the staff of the SEC for any amendment or supplement thereto or for additional information, and shall promptly provide Parent or the Partnership, as applicable, with copies of all correspondence between Parent or the Partnership, as applicable, and the staff of the SEC with respect to the Form S-4 or the Proxy Statement/Prospectus (including a summary of any substantive oral conversations).

(d) If at any time prior to the Effective Time any information relating to Parent or the Partnership, or any of their respective affiliates, officers or directors, is discovered by Parent or the Partnership which should be set forth in an amendment or supplement to any of the Form S-4 or the Proxy Statement/Prospectus, so that any 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 shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by applicable Law, disseminated to the holders of Partnership Common Units.

(e) The Partnership, commencing upon the initial submission to the SEC of the Form S-4, shall, until it has established a record date, on a bi-weekly basis, instruct its Representatives to run a broker search for a deemed record date of 20 business days after the date of such search. The Partnership, Partnership GP and Partnership Managing GP shall use reasonable best efforts to (i) duly establish the earliest practicable record date for determining Partnership unitholders entitled to vote at the Partnership Unitholders’ Meeting in accordance with the Partnership Organizational Documents, (ii) promptly following the SEC Clearance Date, duly establish the earliest practicable date for a meeting of holders of Partnership Common Units to obtain the Partnership Unitholder Approval (the “Partnership Unitholders’ Meeting”) in accordance with the Partnership Organizational Documents, and in any event within 40 days after the date the definitive Proxy Statement/Prospectus is first mailed to Partnership unitholders (unless a later date is required by applicable Law or the Existing Partnership Agreement) and (iii) promptly following the SEC Clearance Date, subject to Section 5.4, solicit proxies to obtain the Partnership Unitholder Approval at the Partnership Unitholders’ Meeting; provided, however, that the Partnership may postpone or adjourn the Partnership Unitholders’ Meeting (A) in compliance with applicable Laws if (1) there are holders of an insufficient number of Partnership Common Units present or represented by proxy at the Partnership Unitholders’ Meeting to constitute a quorum at such meeting (in which case the Partnership shall, and shall cause its proxy solicitor to use reasonable best efforts to, solicit as promptly as practicable the presence, in person or by proxy of a quorum), but only until there are a sufficient number of Partnership Common present or represented by proxy at the Partnership Unitholders’ Meeting to obtain such a quorum, (2) on a date for which the Partnership Unitholders’ Meeting is scheduled, the Partnership has not received proxies representing a sufficient number of Partnership Common Units and Partnership Preferred Units to obtain the Partnership Unitholder Approval, in order to solicit additional proxies from holders of Partnership Common Units for the purposes of obtaining the Partnership Unitholder Approval, but only until there are a sufficient number of Partnership Common Units present or represented by proxy at the Partnership Unitholders’ Meeting to obtain the Partnership Unitholder Approval or (3) to the extent it could reasonably be expected to be necessary to ensure that any supplement or amendment to the Proxy Statement/Prospectus that is required by applicable Laws is disclosed to the holders of Partnership Common Units; provided, however, that with respect to postponement in the case of clauses (1) and (2), the Partnership GP shall not change the record date for the Partnership Unitholders’ Meeting without Parent’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed); and (B) with Parent’s prior written consent. Notwithstanding the foregoing, in the event the Partnership postpones or adjourns the Partnership Unitholders’ Meeting pursuant to the foregoing sentence, the Partnership shall use its reasonable best efforts to reconvene and hold a Partnership Unitholders’ Meeting as promptly as reasonably practicable. Subject to Section 5.4, the Partnership shall use its reasonable best efforts to obtain the Partnership Unitholder Approval, including soliciting proxies therefor.

Section 5.7 Employee Matters.

(a) Following the Effective Time and until the first anniversary of the Closing Date (or, if earlier, the date of termination of employment of an applicable Current Employee), Parent shall, or shall cause one of its Subsidiaries to, provide the individuals who are employed by the Partnership or any of the Partnership Subsidiaries immediately before the Effective Time (the “Current Employees”) and who continue employment during such time period with (i) annual base salary or hourly wage rate (as applicable) that is no less favorable than the annual base salary or hourly wage rate (as applicable) provided to such Current Employees immediately prior to the Effective Time, (ii) a target annual cash incentive compensation opportunity (expressed as a percentage of base salary) and a target long-term incentive compensation opportunity (expressed as a percentage of base salary) that, together in the aggregate, are no less favorable than the target annual cash incentive compensation opportunity (expressed as a percentage of base salary) and target long-term incentive compensation opportunity (expressed as a percentage of base salary) that, together in the aggregate, were provided to such Current Employees immediately prior to the Effective Time, and (iii) employee benefits (excluding any defined benefit and supplemental pensions, retiree or post-termination health or welfare benefits, and retention or change in control payments or other special or one-time awards (collectively, the “Excluded Benefits”)) that are substantially comparable in the aggregate to the other compensation and employee benefits (subject to the same exclusions) provided to similarly situated employees of Parent and its Subsidiaries. In the event that, following the Effective Time and until the second anniversary of the Closing Date, a Current Employee experiences a severance-qualifying termination of employment as described on Section 5.7(a) of the Partnership Disclosure Schedule, such Current Employee shall be entitled to severance benefits pursuant to the formula set forth on Section 5.7(a) of the Partnership Disclosure Schedule, subject to such Current Employee’s execution of a customary release and waiver of claims (which shall not include any restrictive covenants); provided, however, that such Current Employee is not otherwise entitled to receive severance benefits under any employment, severance, change in control, retention or similar agreement or arrangement between such Current Employee and the Partnership or any of its affiliates. Parent shall honor and comply with, or cause its applicable Subsidiary to honor and comply with, the severance agreements set forth on Section 5.7(a) of the Partnership Disclosure Schedule.

(b) For purposes of vesting, eligibility to participate and determining levels of benefits (but not for any purposes under any plan or program providing for Excluded Benefits and, with respect to benefit accrual, solely to the extent that past service with Parent and its Subsidiaries is credited for similarly situated employees of Parent and its Subsidiaries) under the Benefit Plans of Parent and its Subsidiaries providing benefits (other than those providing Excluded Benefits) to Current Employees after the Effective Time (the “New Plans”), each Current Employee shall be credited with his or her years of service with the Partnership and the Partnership Subsidiaries and their respective predecessors before the Effective Time, to the same extent and for the same purpose as such Current Employee was entitled, before the Effective Time, to credit for such service under any similar Partnership Benefit Plan in which such Current Employee participated or was eligible to participate immediately prior to the Effective Time; provided, however, that the foregoing shall not apply to the extent that its application would result in a duplication of benefits,

compensation or coverage with respect to the same period of service; provided, further, that such service shall only be taken into account to the extent service with Parent and its Subsidiaries is credited for similarly situated employees under any New Plan. In addition, and without limiting the generality of the foregoing, for the plan year that includes the Closing Date, Parent shall, and shall cause its Subsidiaries (as applicable) to provide that (i) each Current Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is comparable to a Partnership Benefit Plan in which such Current Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), (ii) for purposes of each New Plan providing medical, dental, pharmaceutical or vision benefits to any Current Employee cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Current Employee and his or her covered dependents, unless and to the extent the individual, immediately prior to entry in the New Plans, was subject to the same such conditions under the comparable Old Plans, (iii) credit amounts paid under any Old Plan providing medical, dental, pharmaceutical or vision benefits under any corresponding New Plan for purposes of applying the corresponding deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the New Plan with respect to the plan year in which the Effective Time occurs and (iv) assume and honor all accrued, unused vacation and paid time off accrued by the Current Employees prior to the Effective Time.

(c) If requested by Parent not later than five (5) business days prior to the Effective Time, subject to the terms of any such Partnership Benefit Plan and applicable Law, the Partnership shall (i) terminate any Partnership Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement (a “Partnership 401(k) Plan”), (ii) fully vest each Current Employee in his or her account balance in such Partnership 401(k) Plan, and (iii) make or cause to be made to the Partnership 401(k) Plan all employer contributions that would have been made on behalf of the Current Employees had the transaction contemplated by this Agreement not occurred, regardless of any service or end-of-year employment requirements, but prorated for the portion of the plan year that ends on the Closing Date, in each case, effective at least one day prior to the Closing Date (the “ERISA Effective Date”). Prior to the ERISA Effective Date, the Partnership shall provide Parent with draft resolutions of the Partnership Managing GP Board or, as applicable, the Board of Directors of the applicable Partnership Subsidiaries authorizing such termination and amending any such Partnership 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws for Parent’s review and comment (which comments shall be considered in good faith by the Partnership), and shall provide Parent with duly executed versions of such documentation no later than the ERISA Effective Date. If the Partnership 401(k) Plan is terminated pursuant to this Section 5.7(c), then as of immediately after the Effective Time, Parent shall permit all Current Employees who were eligible to participate in the Partnership 401(k) Plan as of immediately prior to the Effective Time to participate in a 401(k) plan maintained by Parent or an affiliate thereof, and Parent shall, or shall cause the applicable affiliate thereof to permit each such Current Employee to elect to transfer his or her account balance (including notes in respect of outstanding loans) when distributed from the terminated Partnership 401(k) Plan to Parent’s 401(k) plan.

(d) Nothing in this Section 5.7 shall be construed as the establishment of an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment, modification or termination of any Benefit Plan or any other compensation or benefit plan, program, policy, agreement or arrangement. Nothing in this Section 5.7 shall limit the right of Parent, the Surviving Entity or any of their Subsidiaries to terminate the employment of any Partnership Employee at any time. Without limiting the generality of Section 8.13, the provisions of this Section 5.7 are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other person shall be a third-party beneficiary of this Agreement, and nothing herein shall be construed as an amendment, modification or termination to any Partnership Benefit Plan, each Benefit Plan sponsored, maintained, contributed to or required to be contributed to by Parent or any of its Subsidiaries, or under which Parent or any of its Subsidiaries has any material liability (contingent or current), or other compensation or benefit plan, program, policy, agreement or arrangement (including any New Plan) for any purpose.

In the event any public disclosure is required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, the disclosing party will endeavor, on a basis reasonable under the circumstances, to provide a meaningful opportunity to Parent and/or the Partnership, as applicable, to review and comment upon such press release or other announcement or disclosure in advance and shall give due consideration to all reasonable additions, deletions or changes suggested thereto.

Section 5.11 Indemnification and Insurance.

(a) For a period of six (6) years after the Effective Time, Parent shall cause the Surviving Entity and its Subsidiaries to indemnify and hold harmless, and provide advancement of expenses to, their respective current or former directors and officers and any person who becomes a director or officer of any of the Partnership or the Partnership Subsidiaries prior to the Effective Time (the “Indemnified Parties”) to the fullest extent that applicable Laws permit such Surviving Entity to indemnify its own directors and officers. In addition, for a period of six (6) years after the Effective Time, Parent shall cause to be maintained in effect (i) the provisions regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses in the Partnership Organizational Documents and the organizational documents of the Partnership Subsidiaries and (ii) any indemnification agreement of the Partnership, the Partnership GP or a Partnership Subsidiary with any Indemnified Party in existence as of the entry into this Agreement, except to the extent that such agreement provides for an earlier termination, in each case, that are in existence as of the entry into this Agreement, and no such provision shall be amended, modified or repealed in any manner that would adversely affect the rights or protections thereunder of any such Indemnified Party in respect of acts or omissions occurring or alleged to have occurred at or prior to the Effective Time (including acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger or any of the other transactions contemplated by this Agreement).

(b) For a period of six (6) years following the Effective Time, the Surviving Entity shall cause to be maintained in effect the existing policy of the Partnership’s and/or the Partnership Managing GP’s directors’ and officers’ liability insurance (or a comparable replacement policy) (the “D&O Policy”) covering claims arising from facts or events that occurred at or prior to the Effective Time to the extent that such claims are of the type covered by the D&O Policy (including for acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby to the extent that such acts or omissions are covered by the D&O Policy) and covering each Indemnified Party who is covered as of the Effective Time by the D&O Policy, in any case on terms with respect to coverage and amounts that are no less favorable in the aggregate than those terms in effect on the date hereof; provided, that in no event shall Parent or the Surviving Entity be required to expend in any one year an amount in excess of 300% of the larger of the current annual premium paid by the Partnership for such insurance (the larger such 300% amount, the “Maximum Annual Premium”); and provided further, that if the annual premium of such insurance coverage exceeds the Maximum Annual Premium, Parent and the Surviving Entity shall be obligated to obtain a policy with the greatest comparable coverage available for a cost not exceeding the Maximum Annual Premium. Notwithstanding anything to the contrary in this Agreement, in lieu of its obligations under the first sentence of this Section 5.11(b), Parent or the Partnership may purchase a six (6)-year “tail” prepaid policy on the D&O Policy on terms with respect to coverage and amounts no less favorable in the aggregate than the D&O Policy, and in the event that Parent or the Partnership purchases such a “tail” policy, Parent or the Surviving Entity, as applicable, shall maintain such “tail” policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other applicable obligations of the Surviving Entity under the first sentence of this Section 5.11(b) for so long as such “tail” policy shall be maintained in full force and effect (provided, that such obligations shall not be deemed satisfied if such “tail” policy is not in effect at least six (6) years from the Effective Time).

(c) The obligations under this Section 5.11 shall not be terminated, amended or otherwise modified in such a manner as to adversely affect any Indemnified Party (or any other person who is a beneficiary under the D&O Policy or the “tail” policy referred to in Section 5.11(b) and any of such person’s heirs and Representatives) without the prior written consent of such affected Indemnified Party or other person who is a beneficiary under the D&O Policy or the “tail”

policy referred to in Section 5.11(b) (and, after the death of any of the foregoing persons, such person’s heirs and Representatives). Each of the Indemnified Parties or other persons who are beneficiaries under the D&O Policy or the “tail” policy referred to in Section 5.11(b) (and, after the death of any of the foregoing persons, such person’s heirs and Representatives) are intended to be third party beneficiaries of this Section 5.11, with full rights of enforcement as if a party thereto. The rights of the Indemnified Parties (and other persons who are beneficiaries under the D&O Policy or the “tail” policy referred to in Section 5.11(b) (and their heirs and Representatives)) under this Section 5.11 shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificate of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Partnership or any Partnership Subsidiaries, or applicable Laws (whether at law or in equity).

(d) In the event that the Surviving Entity or any of its Subsidiaries (or any of their respective successors or assigns) shall consolidate or merge with any other person and shall not be the continuing or surviving entity in such consolidation or merger, then in each case, to the extent necessary to protect the rights of the Indemnified Parties and other persons who are beneficiaries under the D&O Policy or the “tail” policy referred to in Section 5.11(b) (and their respective heirs and Representatives), proper provision shall be made so that the continuing or surviving corporation or Entity (or its successors or assigns, if applicable) shall assume the obligations set forth in this Section 5.11.

Section 5.12 Control of Operations. Without in any way limiting any party’s rights or obligations under this Agreement, the parties understand and agree that (a) nothing contained in this Agreement shall give Parent or the Partnership, directly or indirectly, the right to control or direct the other party’s operations prior to the Effective Time and (b) prior to the Effective Time, each of the Partnership and Parent shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

Section 5.13 Section 16 Matters. Prior to the Effective Time, Parent, the Partnership, Partnership GP and Partnership Managing GP shall take all such steps as may be required to cause any dispositions of Partnership Units (including derivative securities with respect to Partnership Units) or acquisitions of Parent Units (including derivative securities with respect to Parent 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.

Section 5.14 Intended Tax Treatment.

(a) Parent and the Partnership each acknowledge and agree that, for U.S. federal and applicable state and local income tax purposes, (i) the Merger is intended to be treated as an exchange described in Section 721(a) of the Code pursuant to which the holders of Partnership Common Units contribute such Partnership Common Units to Parent in exchange for Parent Common Units pursuant to the Merger, (ii) neither the Partnership nor any partner of the Partnership is intended to recognize gain for U.S. federal income tax purposes in connection with the Merger (other than (x) gain resulting from (A) any decrease in a partner’s share of partnership liabilities (as determined pursuant to Section 752 of the Code and the Treasury Regulations

promulgated thereunder), (B) the receipt of cash in lieu of fractional Parent Common Units, (C) any distribution of cash or property by Parent (other than to the extent such distribution qualifies as an “operating cash flow distribution” within the meaning of Treasury Regulations Section 1.707-4(b)(2)), (D) any sale of Parent Units pursuant to Section 2.5 or (E) the Special Distribution, or (y) in the case of any non-U.S. holder of Partnership Common Units, gain subject to tax as a result of the application of Section 897, Section 1445 or 1446 of the Code and the Treasury Regulations thereunder), and (iii) the Special Distribution is intended to be treated as a payment of a distribution under Section 731 of the Code from the Partnership to holders of Partnership Common Units (clauses (i) through (iii), the “Intended Tax Treatment”). Except to the extent required to do so as a result of a “determination” as defined in Section 1313(a) of the Code, each of Parent and the Partnership will not (and will cause its respective controlled affiliates not to) make any tax filings or otherwise take any position inconsistent with the Intended Tax Treatment or Section 5.14(e) and will (and will cause its respective controlled affiliates to) cooperate with the other party to make any filings, statements or reports required to effect, disclose or report the Intended Tax Treatment.

(b) Each of Parent and the Partnership will (and will cause its respective controlled affiliates to) use its reasonable best efforts to cause the Merger to qualify for the Intended Tax Treatment, and will not take or knowingly fail to take (and will cause its respective controlled affiliates not to take or knowingly fail to take) any actions if such actions or the failure to take such actions would reasonably be expected to prevent or impede the Merger from qualifying for the Intended Tax Treatment. Each of Parent and the Partnership shall notify the other party promptly after becoming aware of any fact or circumstance that could reasonably be expected to (i) cause the Merger to fail to qualify for the Intended Tax Treatment or (ii) prevent or impede the receipt of any of the Required Tax Opinions.

(c) Each of Parent and the Partnership will use its reasonable best efforts and will reasonably cooperate with one another to obtain the opinions of counsel referred to in Section 6.1(d), Section 6.1(e), Section 6.2(e) and Section 6.2(f) (the “Required Tax Opinions”). In connection therewith, (i) Parent shall deliver to requisite counsels (A) in connection with the opinions of counsel referred to in Section 6.1(d), Section 6.1(e) and Section 6.2(f), one or more duly executed certificates in form and substance reasonably satisfactory to such counsels containing such customary representations as shall be reasonably necessary or appropriate to enable such counsels to render such Required Tax Opinions and (B) in connection with the opinion of counsel referred to in Section 6.2(e), a duly executed certificate in form and substance consistent with the certificate set forth in Section 5.14(c) of the Parent Disclosure Schedule (the certificates referenced in clause (A) and (B) together, the “Parent Tax Certificates”) and (ii) the Partnership shall deliver to requisite counsels (A) in connection with the opinions of counsel referred to in Section 6.1(d), Section 6.1(e) and Section 6.2(f), one or more duly executed certificates in form and substance reasonably satisfactory to such counsels containing such customary representations as shall be reasonably necessary or appropriate to enable such counsels to render such Required Tax Opinions and (B) in connection with the opinion of counsel referred to in Section 6.2(e), a duly executed certificate in form and substance consistent with the certificate forth in Section 5.14(c) of the Partnership Disclosure Schedule (the certificates referenced in clause (A) and (B) together, the “Partnership Tax Certificates”), in each case dated as of the Closing Date (and, if requested, Parent and the Partnership shall deliver such certificates to requisite counsels in connection with any opinions to be filed in connection with the Form S-4, dated as of the date of such opinions), and Parent and the Partnership shall provide such other information as shall be reasonably requested by counsels for purposes of rendering the Required Tax Opinions (or any opinions to be filed in connection with the Form S-4).

(d) Subject to the following sentence, Parent shall prepare and file any U.S. federal (and applicable state and local) income Tax Returns for the Partnership and its Subsidiaries for the tax year including the Closing Date (and any prior years for which such Tax Returns are required to be filed after the Effective Time) in accordance with the past practices of the Partnership or such Subsidiaries. The Partnership and Parent agree that all items of income, gain, loss, deduction and credit of the Partnership (and any Subsidiary of the Partnership that is treated as a partnership for U.S. federal income tax purposes) for the taxable year during which the Closing Date occurs will be allocated between (i) the portion of such taxable year that ends on the Closing Date and (ii) the portion of such taxable year that begins on the date immediately after the Closing Date using an interim closing of the books pursuant to Section 706 of the Code.

(e) Parent shall cause the Partnership to remain treated as a partnership, for U.S. federal income tax purposes, that is regarded as separate from Parent, making the assumptions set forth in Section 5.14(e) of the Partnership Disclosure Schedule, from immediately prior to the Effective Time until a date that is at least one (1) year following the Closing.

Section 5.15 Partnership Credit Agreement; Partnership Receivables Financing Agreement.

(a) The Partnership shall, prior to the Closing, following a request in writing by Parent, (i) deliver (or cause to be delivered) notices of prepayment or termination of the Partnership Credit Agreement and Partnership Receivables Financing Agreement (which notices shall be conditioned upon the consummation of the Closing) within the time periods required thereunder and (ii) take all other actions reasonably required to facilitate the termination of the commitments thereunder and the release of any Liens and termination of all guarantees granted in connection therewith, in each case on the Closing Date, subject to the payment by the Partnership of the Payoff Amount pursuant to Section 5.15(b); and

(b) The Partnership shall, at least one (1) business day prior to the Closing Date, following a request in writing by Parent, deliver or cause to be delivered to Parent in escrow (subject to release on the Closing Date) customary payoff letters, in form reasonably acceptable to Parent, from the administrative agent and collateral agent under the Partnership Credit Agreement and from the administrative agent and collateral agent under the Partnership Receivables Financing Agreement (each, a “Payoff Letter”), specifying the total payment required to be made as of the Closing Date to repay in full all obligations under each of the Partnership Credit Agreement and the Partnership Receivables Financing Agreement (including interest, premiums, penalties, make-whole payments, breakage costs and other fees and expenses (if any) that are required to be paid by the Partnership or any Partnership Subsidiary as a result of such repayment on the Closing Date), together with pay-off instructions for making such repayment on the Closing Date (such amounts under the Partnership Credit Agreement and the Partnership Receivables Financing Agreement collectively, the “Payoff Amount”). Parent shall provide (or cause to be provided) all funds to pay the Payoff Amount set forth in the Payoff Letters on the Closing Date.

Section 5.16 Stock Exchange Listing. Parent shall cause the Parent Units to be issued in the Merger and such other Parent Units to be reserved for issuance in connection with the Merger to be approved for listing on the NYSE, subject to official notice of issuance, as promptly as reasonably practicable, and in any event prior to the Closing Date. Prior to filing the listing application or notification form or responding to any comments of the NYSE with respect thereto, Parent shall provide the Partnership with a reasonable opportunity to review and comment on such document or response (including the proposed final version of such document or response). The Partnership shall use reasonable best efforts to furnish all information concerning itself and its affiliates and provide such other assistance as may be reasonably requested by Parent in connection with the preparation and filing of the listing application or notification form (or any amendment or supplement thereto) or in connection with responding to any comments of the NYSE with respect thereto.

Without limiting in any way the respective applicable obligations of Parent and the Partnership under Section 5.1 and Section 5.8, each of Parent, the Parent GP and the Partnership and their controlled affiliates shall, and shall use reasonable best efforts to cause their respective other affiliates to, give the other the opportunity to participate in the defense or settlement of any unitholder claim or unitholder legal proceeding (including any class action or derivative litigation) against such party or its affiliates or its or their officers, general partners or directors relating to the transactions contemplated by this Agreement, and no such settlement shall be agreed to, without the prior written consent of Parent and the Partnership, which consent with respect to any such settlement shall not be unreasonably withheld, conditioned or delayed. Each of Parent and the Partnership and their respective controlled affiliates shall, and shall use reasonable best efforts to cause their respective other affiliates to cooperate and shall use its reasonable best efforts to cause its Representatives to cooperate, in the defense against such claim or legal proceeding.

Section 5.18 Distributions. Subject to Section 5.27, after the entry into this Agreement until the Closing Date, each of the Partnership and Parent shall coordinate with the other regarding the declaration of any distributions in respect of Parent Common Units and any distributions in respect of Partnership Units and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Parent Common Units and Partnership Common Units shall not receive two (2) distributions (it being understood that the Special Distribution shall not be counted for this purpose) or fail to receive one distribution, as applicable, in any quarter with respect to their Parent Common Units or Partnership Units and any Parent Common Units any holder of Partnership Units receives in exchange therefor in the Merger. For the avoidance of doubt, this Section 5.18 shall not limit the right of the Partnership to declare and pay (and set a record date for) the Special Distribution in accordance with Section 5.27.

Prior to the earlier of the Effective Time and the Termination Date, the Partnership will cooperate with Parent and use its reasonable best efforts to take, or cause to be taken, all actions and do, or cause to be done, all things reasonably necessary, proper or advisable on its part pursuant to applicable Law and the rules and regulations of NYSE to cause (a) the delisting of the Partnership Common Units from NYSE as promptly as practicable after the Effective Time; and (b) the deregistration of the Partnership Common Units pursuant to the Exchange Act as promptly as practicable after such delisting.

All documentation regarding the foregoing shall be subject to the review and approval (not to be unreasonably withheld, conditioned or delayed) of Parent. Parent shall provide (or cause to be provided) all funds for the Redemptions as required by the Redemptions.

(xi) that would require its legal counsel to provide any legal opinions or 10b-5 letters;

(xii) other than as contemplated by Section 5.21(a)(v) and (vii) above, that would require the Partnership or the Partnership Subsidiaries to prepare any pro formas, projections or forecasts or provide financial statements that are not prepared in the ordinary course of its financial reporting practice;

(xiii) that would require the Partnership or the Partnership Subsidiaries to disclose (if not previously publicly disclosed by the Partnership) any preliminary financial results or “flash numbers”; and

(xiv) that would require the Partnership to file or furnish any reports or information with the SEC in connection with such financing.

(c) Parent shall indemnify and hold harmless the Partnership and Partnership Subsidiaries and their respective directors, officers, employees, equityholders, Representatives, advisors and affiliates from and against any out-of-pocket costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, or damages suffered or incurred by any of them in connection with the Debt Financing to the fullest extent permitted by law and any information utilized in connection therewith except to the extent any such cost or expense, judgment, fine, loss, claim, or damage results from the bad faith, gross negligence, fraud, intentional misrepresentation or willful misconduct by the Partnership, the Partnership Subsidiaries or any of their respective affiliates or Representatives. Parent shall promptly, following the Partnership’s written request therefor, reimburse the Partnership and the Partnership Subsidiaries for all reasonable and documented expenses incurred by any of them or their Representatives in connection with fulfilling their respective obligations pursuant to this Section 5.21 (including reasonable and documented out-of-pocket attorneys’ fees).

(d) The Partnership hereby consents, on its own behalf and on behalf of the Partnership Subsidiaries, to (i) the inclusion of Evaluation Material (as defined in the Confidentiality Agreement) in any customary disclosure document for the Debt Financing provided to potential debt providers required to facilitate the Debt Financing to the extent the recipients of such disclosure document are subject to customary confidentiality requirement or the disclosure documents are filed with the SEC and (ii) the use of its logos in connection with the Debt Financing so long as such logos are used in a manner that is not intended to or reasonably likely to harm or disparage the Partnership and the Partnership Subsidiaries or the reputation or goodwill of the Partnership and the Partnership Subsidiaries and their respective products, services, offerings or Intellectual Property rights.

Section 5.22 Committed Financing

(a) Parent shall, and shall cause its Subsidiaries to, use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary, proper or advisable to consummate the Committed Financing or any Substitute Financing in an amount equal to the Required Amount, including, using reasonable best efforts to (i) (A) maintain in effect the Debt Commitment Letter and (B) negotiate, enter into and deliver definitive agreements with respect to the Committed Financing reflecting the terms contained in the Debt Commitment Letter (or with other terms agreed by Parent and the Financing Sources, subject to the restrictions on amendments of the Debt Commitment Letter set forth below), so that such any such agreements (other than customary post-closing agreements/deliverables) are in effect no later than the Closing and (ii) satisfy on a timely basis all the conditions to the Committed Financing and the definitive agreements related thereto that are in Parent’s (or its Subsidiaries’) control. Parent shall pay, or cause to be paid, as the same shall become due and payable, all fees and other amounts under the Debt Commitment Letter.

(b) Following the reasonable request therefor, Parent shall keep the Partnership reasonably informed on a timely basis of the status of Parent’s and its Subsidiaries’ efforts to obtain the Committed Financing, including providing copies of any amendment, modification or replacement of the Debt Commitment Letter (provided, that any fee letter may be redacted to remove the fee amounts, the rates and amounts included in the “market flex” and other economic terms that could not adversely affect the conditionality, enforceability, termination or aggregate principal amount of the Committed Financing) and shall give the Partnership prompt notice of (x) any material breach or default by any party to the Debt Commitment Letter or the definitive documentation related thereto of which Parent has become aware and (y) any condition precedent of the Committed Financing that Parent has any reason to believe will not be satisfied at the Closing Date; provided that neither Parent nor any of its affiliates shall be under any obligation to disclose any information that is subject to attorney-client or similar privilege to the extent such privilege is asserted in good faith or otherwise would violate or contravene any law or any obligation of confidentiality. Parent may amend, modify, replace, terminate, assign or agree to any waiver under the Debt Commitment Letter without the prior written approval of the Partnership; provided that Parent shall not, without the Partnership’s prior written consent, permit any such amendment, replacement, modification, assignment, termination or waiver to be made to, or consent to any waiver of, any provision of or remedy under the Debt Commitment Letter which would (i) reduce the aggregate cash amounts of the Committed Financing (including by increasing the amount of fees to be paid or original issue discount) unless the aggregate amount of the Committed Financing following such reduction, together with cash on hand and other sources of funds of Parent on the Closing Date, would be equal to, or in excess of, the Required Amount, (ii) (x)impose new or additional conditions to the Committed Financing or (y) otherwise expand, amend, modify or waive any of the conditions to the Committed Financing or (iii) otherwise expand, amend, modify or waive any provision of the Debt Commitment Letter in a manner that, in the case of subclauses (ii)(y) or (iii), would reasonably be expected to (A) prevent, materially impair or materially delay the funding of the Committed Financing (or satisfaction of the conditions to the Committed Financing) on the Closing Date or (B) materially adversely affect the ability of Parent or any of its Subsidiaries to pay the Required Amounts at Closing; provided that notwithstanding the foregoing, Parent may modify, supplement or amend the Debt Commitment Letter to (1) add lenders, lead arrangers, bookrunners, syndication agents or similar entities that have not executed the Debt Commitment Letter as of the date of this Agreement and (2) implement or exercise any “market flex” provisions contained in the Debt Commitment Letter. In the event that new commitment letters or fee letters are entered into in accordance with any amendment, replacement, supplement or other modification of the Debt Commitment Letter permitted pursuant to this Section 5.22 such new commitment letters or fee letters shall be deemed to be the “Debt

Commitment Letter” for all purposes of this Agreement and references to “Committed Financing” herein shall include and mean the financing contemplated by the Debt Commitment Letter as so amended, replaced, supplemented or otherwise modified, as applicable. Parent shall promptly deliver to the Partnership copies of any termination, amendment, modification, waiver or replacement of the Debt Commitment Letter.

(c) If funds in the amounts set forth in the Debt Commitment Letter, or any portion thereof, become unavailable (other than in accordance with the terms of the Debt Commitment Letter), Parent shall, and shall cause its Subsidiaries to, as promptly as practicable following the occurrence of such event (i) notify the Partnership in writing thereof and (ii) use reasonable best efforts to obtain substitute financing, including, as applicable, a commitment to provide such substitute financing (on terms that are not materially less favorable to Parent, taken as a whole, than the terms as set forth in the Debt Commitment Letter, taking into account any “market flex” provisions thereof, and which does not include any conditions to the consummation of such substitute financing that are more onerous than the conditions set forth in the Committed Financing) sufficient, together with cash on hand and other sources of funds of Parent on the Closing Date, to enable Parent and its Subsidiaries to pay the Required Amount at Closing (the “Substitute Financing”) and, promptly after execution thereof, deliver to the Partnership true, complete and correct copies of the new commitment letter and the related fee letters (in redacted form removing the fee amounts, the rates and amounts included in the “market flex” and other economic terms that could not adversely affect the conditionality, enforceability, termination or aggregate principal amount of the Committed Financing) or related definitive financing documents with respect to such Substitute Financing. Upon obtaining any commitment for any such Substitute Financing, such financing shall be deemed to be a part of the “Committed Financing” and any commitment letter for such Substitute Financing shall be deemed to be the “Debt Commitment Letter” for all purposes of this Agreement.

(d) Notwithstanding the foregoing, compliance by Parent and its Subsidiaries with this Section 5.22 shall not limit or modify the Partnership’s right to seek specific performance to cause Parent to consummate the Merger, whether or not the Debt Financing is available.

Section 5.23 General Partner Obligations. Each of the Parent GP and the Partnership Managing GP shall take all action necessary to cause Parent and the Partnership, as applicable, to perform its obligations under this Agreement and to consummate the transactions contemplated by this Agreement, including the Merger, upon the terms and subject to the conditions set forth in this Agreement. For the avoidance of doubt, any violation of the obligations of Parent or the Partnership under this Agreement shall also be deemed to be a breach of this Agreement by the Parent GP or the Partnership Managing GP, as applicable.

Section 5.24 Obligations of Merger Sub and Parent. Parent shall take all action necessary to cause Merger Sub to perform its obligations under this Agreement and to consummate the transactions contemplated by this Agreement, including the Merger, upon the terms and subject to the conditions set forth in this Agreement.

Immediately after the execution of this Agreement, Parent shall deliver to the Partnership evidence of the adoption of this Agreement by Parent, in its capacity as the sole member of Merger Sub, and the consent effecting such adoption shall not be modified or withdrawn after the entry into this Agreement.

Section 5.25 Third-Party Consents. From the entry into this Agreement and prior to the earlier of the Effective Time and the Termination Date, the Partnership shall use commercially reasonable efforts to (a) seek the consents of, and deliver the notices and certificates to, as applicable, each of the parties (other than the Partnership and the Partnership Subsidiaries) to the contracts listed on Section 5.25 of the Partnership Disclosure Schedule to the extent required in connection with the transactions contemplated by this Agreement and (b) take all reasonable action to satisfy any legal or contractual requirements to provide notice to or enter into any consultation procedure with any labor union, labor organization, or works council which is representing any Partnership Employee in connection with the transactions contemplated by this Agreement. Notwithstanding the foregoing, in connection with the foregoing, neither the Partnership nor any of the Partnership Subsidiaries nor any of their respective affiliates shall be required to (i) make any payment of a consent fee, “profit sharing” payment or other consideration (including increased or accelerated payments) or concede anything of value, (ii) amend, supplement or otherwise modify any contract or (iii) agree or commit to do any of the foregoing, and any failure to do so shall not be considered, by itself, a breach of this Section 5.25. The parties hereby acknowledge and agree that none of the consents, requirements, notices or other actions contemplated by this Section 5.25 shall serve as a condition to the Closing.

Section 5.26 Additional Specified Negative Covenants. Notwithstanding anything to the contrary set forth in this Agreement and not in limitation of any other obligations set forth herein, Parent GP and Parent shall, and shall cause each of their respective Subsidiaries to, from and after the entry into this Agreement until the Effective Time, not acquire (or enter into any agreement to acquire), directly or indirectly by merger, consolidation, acquisition of stock or assets or otherwise, any business, person or assets from any other person if such transaction would reasonably be expected to (a) impose any material delay in the obtaining of, or materially increase the risk of not obtaining, any approval, consent, clearance, non-action or other similar action or inaction from any Governmental Authority required in connection with the transactions contemplated by this Agreement, including the Merger, (b) materially increase the risk of any Governmental Authority enacting, issuing, promulgating, enforcing or entering any Legal Restraint, or (c) materially increase the risk of the parties not being able to remove any such Legal Restraint described in the preceding clause (b).

Section 5.27 Special Distribution. The parties shall coordinate regarding the declaration by the Partnership of a distribution in respect of Partnership Common Units and the record date and payment date relating thereto, such that the holders of Partnership Common Units shall receive, prior to the Effective Time, a special cash distribution (the “Special Distribution”) in the amount of $0.212 per Partnership Common Unit. The Special Distribution shall be declared and paid on, and to holders of record of, Partnership Common Units as of such dates as are mutually agreed upon by Parent and the Partnership (to be no later than the Effective Time) and shall be subject to applicable Law and compliance with the terms of the Existing Partnership Agreement.

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

Section 7.3 Partnership Breakup Fee.

(a) If this Agreement is validly terminated by Parent pursuant to Section 7.1(g) (Change of Recommendation) or the Partnership pursuant to Section 7.1(h) (Superior Proposal), then the Partnership shall pay to Parent within two (2) business days after the date of termination, the Partnership Breakup Fee, by wire transfer of same day federal funds to the account specified by Parent.

(b) If this Agreement is validly terminated (i) Parent pursuant to Section 7.1(f) (Breach of Representation or Covenant), and the breach giving rise to the right to terminate this Agreement pursuant to Section 7.1(f) was the Partnership’s failure to convene and hold a Partnership Unitholders’ Meeting in violation of Section 5.6, or (ii) by Parent or the Partnership pursuant to Section 7.1(d) (No Partnership Unitholder Approval) and, in the case of each of clause (i) and (ii), (A) at or prior to the time of the termination of this Agreement an Acquisition Proposal shall have been publicly disclosed or publicly announced and not have been withdrawn prior to such termination; and (B) on or prior to the twelve (12)-month anniversary of such termination of this Agreement (1) any Acquisition Transaction is consummated or (2) the Partnership or any Partnership Subsidiary enters into a definitive contract providing for any Acquisition Transaction (it being understood that, for purposes of this clause (2), each reference to “20%” in the definition of “Acquisition Transaction” shall be deemed to be a reference to “50%”) which is thereafter consummated, then the Partnership shall pay to Parent an amount equal to the Partnership Breakup Fee, by wire transfer of same day federal funds to the account specified by Parent on the earlier of the public announcement of the Partnership’s entry into such contract or the consummation of any such Acquisition Transaction.

(c) Notwithstanding anything to the contrary in this Agreement, the payment of the Partnership Breakup Fee to Parent pursuant to Section 7.3(a) or Section 7.3(b) shall be the sole and exclusive monetary remedy available to Parent or any of its affiliates in connection with this Agreement and the transactions contemplated by this Agreement in any circumstance in which the Partnership Breakup Fee is payable hereunder, and upon payment by the Partnership of the Partnership Breakup Fee to the account designated by Parent none of the Partnership, the Partnership GP, any Partnership Subsidiary or any of their respective former, current or future officers, directors, partners, unitholders, limited partners, general partners, shareholders, stockholders, managers, members, affiliates, Representatives or other agents shall have any further liability with respect to this Agreement or the transactions contemplated hereby to Parent or any of its affiliates or any of its or their former, current or future officers, directors, partners, unitholders, limited partners, general partners, shareholders, stockholders, managers, members, affiliates, Representatives or other agents; provided, however, that nothing herein shall release the Partnership from liability arising out of or the result of Fraud. The parties acknowledge and agree that in no event shall the Partnership be required to pay the Partnership Breakup Fee on more than one occasion, and in no event shall Parent, Parent GP or Merger Sub be entitled to specific performance to cause the Partnership to consummate the transactions contemplated by this Agreement if Parent has received the Partnership Breakup Fee and vice versa.

It is accordingly agreed that, in addition to any other remedy that may be available to it at law or in equity, each of the parties shall be entitled to an injunction or injunctions or equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), and all such rights and remedies at law or in equity shall be cumulative, except as may be limited by Section 7.3.

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

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

Section 8.10 Entire Agreement.

Section 8.11 Disclosure Schedules. Each of the Partnership Disclosure Schedule and the Parent Disclosure Schedule shall be arranged in separate parts corresponding to the numbered and lettered sections set forth in this Agreement. For purposes of this Agreement any disclosure set forth in any particular Section or subsection of the Partnership Disclosure Schedule or the Parent Disclosure Schedule shall be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (a) the representations, warranties, covenants, agreements or other provisions hereof of the respective Party that are contained in the corresponding Section or subsection of this Agreement, and (b) any other representations, warranties, covenants, agreements or other provisions hereof of the respective party that are contained in this Agreement, but in the case of this clause (b) only if the relevance of that disclosure as an exception to (or a disclosure for purposes of) such representations, warranties, covenants, agreements and other provisions hereof, is reasonably apparent. The mere inclusion of an item in the Partnership Disclosure Schedule or Parent Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission that such item represents a material fact, event or circumstance or that such item has had, or would reasonably be expected to have a Partnership Material Adverse Effect or Parent Material Adverse Effect, as applicable. The Partnership Disclosure Schedule and Parent Disclosure Schedule shall each be delivered as of the entry into this Agreement, and no

amendments or modifications thereto shall be made without the written consent of Parent (in the case of an amendment or modification to the Partnership Disclosure Schedule) or the Partnership (in the case of an amendment or modification to the Parent Disclosure Schedule). Any purported update or modification to the Partnership Disclosure Schedule or the Parent Disclosure Schedule after the entry into this Agreement that is not so consented to shall be disregarded.

Section 8.12 Amendments; Waivers. At any time prior to the Effective Time, any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the Partnership, Partnership GP, Partnership Managing GP, Parent, Parent GP and Merger Sub or, in the case of a waiver, by the party against whom the waiver is to be effective. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 8.13 No Third-Party Beneficiaries. Each of the parties agrees that (a) their respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the applicable parties hereto, in accordance with and subject to the terms of this Agreement, and (b) except for (i) the provisions of Article II and Section 7.2 (of which the holders of Partnership Common Units are express third party beneficiaries as described in the last sentence of this Section 8.13) and Section 5.11 (of which the Indemnified Parties are an express third party beneficiary), and (ii) the right of the holders of Partnership Common Units to receive the Merger Consideration on the terms and conditions of this Agreement (subject to the last sentence of this Section 8.13) this Agreement is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The parties further agree that the holders of Partnership Common Units are express third party beneficiaries of Article II and Section 7.2 and shall have the right to enforce this Agreement and to pursue and recover any remedies, damages or other amounts, whether in law or in equity, to which the holders of Partnership Common Units may be entitled arising out of this Agreement; provided, that, for purposes of efficiency and administrability, in order to enforce such third party beneficiary rights prior to the Closing, the holders of Partnership Common Units shall appoint an agent to act on behalf of the holders of Partnership Common Units (which appointment may be made by amendment to the Partnership Organizational Documents), and such agent shall be entitled to enforce such rights and pursue and recover such remedies, damages or other amounts on behalf of the holders of Partnership Common Units.

Section 8.14 Financing Provisions. Notwithstanding anything in this Agreement to the contrary, the Partnership, on behalf of itself and the Partnership Subsidiaries and each of its controlled affiliates, hereby: (a) agrees that any legal action or proceeding, whether in law or in equity, whether in contract or in tort or otherwise, involving the Financing Sources, arising out of or relating to, this Agreement, the Debt Financing, any transactions contemplated hereby or thereby, or the performance of any services thereunder, shall be subject to the exclusive jurisdiction of any federal or state court in the Borough of Manhattan, New York, New York, so long as such forum is and remains available, and any appellate court thereof and each party hereto irrevocably submits itself and its property with respect to any such legal action to the exclusive jurisdiction of such court, (b) agrees that any such legal action shall be governed by the laws of the State of New

York (without giving effect to any conflicts of law principles that would result in the application of the laws of another state), except as otherwise provided in any agreement relating to the Debt Financing and except to the extent relating to the interpretation of any provisions in this Agreement (including any provision in the Debt Commitment Letter or in any definitive documentation related to the Debt Financing that expressly specifies that the interpretation of such provisions shall be governed by and construed in accordance with the law of the State of Delaware), (c) knowingly, intentionally and voluntarily waives to the fullest extent permitted by applicable law trial by jury in any such legal action or proceeding brought against the Financing Sources in any way arising out of or relating to, this Agreement, the Debt Financing, any transactions contemplated hereby or thereby, or the performance of any services thereunder, (d) agrees that service of process upon the Partnership, the Partnership Subsidiaries or the Partnership’s controlled affiliates in any such legal proceeding or proceeding shall be effective if notice is given in accordance with Section 8.7, (e) irrevocably waives, to the fullest extent that it may effectively do so, the defense of an inconvenient forum to the maintenance of such legal proceeding in any such court, (f) agrees that none of the Financing Sources shall have any liability to the Partnership or any of the Partnership Subsidiaries or any of their respective controlled affiliates or representatives relating to or arising out of this Agreement, the Debt Commitment Letter or the Debt Financing or any transactions contemplated hereby or thereby or the performance of any services thereunder, and (g) agrees that notwithstanding Section 8.13, the Financing Sources are express third party beneficiaries of, and may enforce, any of the provisions of this Section 8.14 and that this Section 8.14 and the definition of “Financing Sources” and any of the defined terms therein may not be amended in a manner adverse to the Financing Sources without the written consent of the Financing Entities (such consent not to be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, nothing in this Section 8.14 shall in any way limit or modify the rights and obligations of Parent under this Agreement, or any Financing Source’s obligations under the Debt Commitment Letter, or the rights of the Partnership and the Partnership Subsidiaries against the Financing Sources with respect to the Debt Financing or any of the transactions contemplated thereby or any services thereunder following the Closing Date.
