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.

4

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

6

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

7

(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).

8

(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.

Section 2.6 Long-Term Incentive Awards.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of any party to this Agreement, each Partnership LTI Award shall become fully vested and shall be cancelled and converted into the right to receive:

(i) With respect to each Partnership Restricted Unit Award, (A) a number of Parent Common Units equal to the product of (x) the number of Partnership Common Units subject to such Partnership Restricted Unit Award immediately prior to the Effective Time, multiplied by (y) the Exchange Ratio and (B) a cash payment equal to the product of (x) the number of Partnership Common Units subject to such Partnership Restricted Unit Award immediately prior to the Effective Time multiplied by the per-unit amount of the Special Distribution.

(ii) With respect to each Partnership Performance Cash Award, an amount in cash equal to two hundred percent (200%) of the target amount of cash pursuant to such Partnership Performance Cash Award, except that for each Partnership Performance Cash Award that constitutes a “carry forward” award as identified in Section 3.2(e) of the Company Disclosure Schedule the cash amount shall equal one hundred percent (100%) of the target amount.

(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.

9

(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.

(d) The Partnership Managing GP Board (or an appropriate committee thereof) shall adopt such resolutions as are reasonably necessary to effectuate the transactions contemplated by this Section 2.6.

Section 2.7 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available to holders of Partnership Units or otherwise with respect to the Merger or the other transactions contemplated by this Agreement.

Section 2.8 Certain Adjustments to Prevent Dilution. If at any time during the period between the entry into this Agreement and the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 7.1 (the “Termination Date”), any change in the outstanding Partnership Common Units or outstanding Parent Common Units shall occur as a result of any reclassification, unit split (including a reverse unit split) or combination, exchange or readjustment of units, or any unit distribution with a record date during such period (excluding, for clarity, the issuance of New Subsidiary Units), the Merger Consideration, the Exchange Ratio and any other similarly dependent items shall be equitably adjusted to provide to Parent, Merger Sub and the holders of Partnership Common Units the same economic effect as contemplated by this Agreement prior to such action, and thereafter, all references in this Agreement to the Merger Consideration, the Exchange Ratio and any other similarly dependent items shall be references to the Merger Consideration, the Exchange Ratio and any other similarly dependent items as so adjusted; provided, however, that nothing in this Section 2.8 shall be deemed to permit or authorize any party hereto to effect any such change that it is not otherwise authorized or permitted to undertake pursuant to this Agreement.

(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

62

(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;

63

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,

69

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.

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.

Unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, each party shall consult with each other before issuing any press release or public statement with respect to the Merger and, subject to the requirements of applicable Law or the rules of any securities exchange, shall not issue any such press release or public statement without the prior written consent of Parent or the Partnership, as applicable. 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. Notwithstanding anything in this Section 5.10 to the contrary, each party shall be permitted to issue press releases or make public announcements or disclosure (a) with respect to any Acquisition Proposal or Acquisition Transaction or a Change of Recommendation not in breach of Section 5.4(e) or any litigation between the parties relating to this Agreement, and (b) that is consistent with previous press releases, public disclosures or public statements made by any party in compliance with this Section 5.10.

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”

75

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

76

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).

77

(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.

78

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.

Section 5.17 Unitholder Litigation. 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.

Section 5.19 Stock Exchange Delisting; Deregistration. 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.

79

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.

Section 5.21 Financing.

(a) The Partnership shall, and shall cause the Partnership Subsidiaries and their respective Representatives to, in each case, use its and their reasonable best efforts to, provide Parent all customary cooperation reasonably requested by Parent in connection with debt provided pursuant to the Debt Commitment Letter or other debt financing to fund the Required Amount (the “Debt Financing”), including using reasonable best efforts to:

80

(iv) to the extent timely requested, provide, at least five (5) business days prior to the Closing Date, all documentation and other information required by bank regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act, relating to any of the Partnership or any Partnership Subsidiary, in each case as reasonably requested by Parent or any of its affiliates or Representatives or any Financing Sources at least five (5) business days prior to the aforementioned date of delivery;

(b) Notwithstanding anything to the contrary in this Section 5.21, the Partnership and the Partnership Subsidiaries shall not be required to provide cooperation or take action under this Section 5.21:

83

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

84

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. For the avoidance of doubt, any violation of the obligations of Merger Sub under this Agreement shall also be deemed to be a breach of this Agreement by Parent. 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.

85

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.

ARTICLE VII

TERMINATION

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

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

90

(b) by either the Partnership or Parent, if the Merger shall not have been consummated on or before the date that is nine (9) months after the date of this Agreement (the “End Date”); provided, however, that if, as of the applicable End Date, all of the conditions to Closing set forth in Article VI have been satisfied or waived (or by their nature are to be satisfied at the Closing) except, to the extent applicable, for the conditions set forth Section 6.1(b), or Section 6.1(c), then either Parent or the Partnership may cause the End Date to be extended on two (2) separate occasions by a period of three (3) months each, by delivering written notice to the other party, and if so extended, such date shall be the “End Date”; provided further, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to any party whose breach or affiliates’ breach of its obligations in this Agreement (and, in the case of Parent, also ET’s breach of its obligations in the ET Support Agreement) has contributed, in any material respect, to the failure of the Closing to occur on or prior to the End Date;

(c) by either the Partnership or Parent, if the consummation of the Closing would violate any final and nonappealable Legal Restraint; provided, however, that no party shall be permitted to terminate this Agreement pursuant to this Section 7.1(c) whose breach or affiliates’ breach of any provision of this Agreement (and, in the case of Parent, also ET’s breach of its obligations in the ET Support Agreement) contributed, in any material respect, to the issuance or continued existence of such Legal Restraint;

(d) by either the Partnership or Parent, if the Partnership Unitholders’ Meeting (including any adjournments or postponements thereof) shall have concluded, at which a vote upon the approval and adoption of this Agreement was taken, and the Partnership Unitholder Approval shall not have been obtained;

(e) by the Partnership, if ET, Parent, the Parent GP or Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement or the ET Support Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, is not cured by ET, Parent, the Parent GP or Merger Sub within the earlier of 30 days after written notice from the Partnership to Parent describing such breach or failure in reasonable detail and the End Date; provided, however, that, for purposes of clauses (i) and (ii) above, if an inaccuracy in any of Parent, Parent GP, ET or Merger Sub’s representations and warranties (as of the date of this Agreement or as of a date subsequent to the date of this Agreement) or a breach of a covenant or obligation by Parent, Parent GP, ET or Merger Sub is curable by the End Date and Parent or Merger Sub, as applicable, is continuing to exercise its reasonable best efforts to cure such inaccuracy or breach, then the Partnership may not terminate this Agreement under this Section 7.1(e) on account of such inaccuracy or breach, unless such inaccuracy or breach shall remain uncured for a period of 30 days commencing on the date that Partnership gives Parent notice of such inaccuracy or breach;

(f) by Parent, if the Partnership, Partnership GP or Partnership Managing GP shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, is not cured by the Partnership, Partnership GP or Partnership Managing GP within the earlier of 30 days after written notice from

91

Parent to the Partnership describing such breach or failure in reasonable detail and the End Date; provided, however, that, for purposes of clauses (i) and (ii) above, if an inaccuracy in any of the Partnership, Partnership GP or Partnership Managing GP’s representations and warranties (as of the date of this Agreement or as of a date subsequent to the date of this Agreement) or a breach of a covenant or obligation by the Partnership, Partnership GP or Partnership Managing GP is curable by the End Date and the Partnership, Partnership GP or Partnership Managing GP, as applicable, is continuing to exercise its reasonable best efforts to cure such inaccuracy or breach, then Parent may not terminate this Agreement under this Section 7.1(f) on account of such inaccuracy or breach, unless such inaccuracy or breach shall remain uncured for a period of 30 days commencing on the date that Parent gives the Partnership notice of such inaccuracy or breach;

(g) by Parent, prior to the Partnership Unitholder Approval in the event of a Change of Recommendation; and

(h) by the Partnership, prior to the Partnership Unitholder Approval in accordance with Section 5.4(e) in order to accept a Superior Proposal and enter into an agreement providing for a Superior Proposal.

In the event of termination of this Agreement pursuant to Section 7.1, this Agreement shall terminate (except for the provisions of this Section 7.2, Section 7.3, Article VIII and Article IX), and there shall be no other liability on the part of the Partnership, Partnership GP or Partnership Managing GP on the one hand, and Parent or Merger Sub, and Parent GP to the other except as provided in Section 7.3 and, subject to Section 7.3(c), liability (which the parties acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs, and, in the case of liabilities or damages payable by Parent, Parent GP or Merger Sub, would include the benefits of the transactions contemplated by this Agreement lost by the Partnership’s unitholders (taking into consideration all relevant matters, including lost stockholder premium, other combination opportunities and the time value of money)) arising out of or the result of, a party’s (and, in the case of Parent, also ET’s) Fraud or any Willful Breach of any covenant or agreement in this Agreement or the ET Support Agreement occurring prior to termination or as provided for in the Confidentiality Agreement (which shall continue pursuant to the terms thereof) or ET Support Agreement, in which case, subject to Section 7.3(c), the aggrieved party shall be entitled to all rights and remedies available at law or in equity.

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.

92

(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. In addition, the parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement and are not a penalty, and that, without these agreements, neither party would enter into this Agreement. If the Partnership fails to pay promptly the amounts due pursuant to this Section 7.3 other than due to a failure of Parent to provide the Partnership with wire instructions, the Partnership will also pay to Parent interest on the unpaid amount under this Section 7.3, accruing from its due date, at an interest rate per annum equal to two (2) percentage points in the excess of the prime commercial lending rate quoted by The Wall Street Journal and the reasonable and documented out-of-pocket expenses (including reasonable and documented out-of-pocket legal fees) in connection with any action taken to collect payment. Any change in the interest rate hereunder resulting from a change in such prime rate will be effective at the beginning of the date of such change in such prime rate.

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

Section 8.11 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

97

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).

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.

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.

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.

In addition, but without limiting the proviso at the end of Section 3(b), ET shall not take any actions primarily intended to interfere with the consummation of the Merger and the transactions contemplated by the Merger Agreement or otherwise primarily intended to result in Parent, Parent GP or Merger Sub breaching its obligations under the Merger Agreement or this Agreement.

Without limiting the terms of Section 2(b) or Section 3(d) hereof, ET hereby authorizes the Partnership and Parent to publish and disclose in any public filing made in connection with this Agreement and the Merger Agreement and the transactions contemplated hereby and thereby, including the Merger (including the Form S-4 and/or Proxy Statement/Prospectus), and in any other announcement or disclosure required by the SEC or other applicable Law, ET’s identity and ownership of its interests in Parent, Parent GP and Merger Sub and the nature of ET’s obligations under this Agreement.

5. Amendment and Modification. Neither this Agreement nor any term hereof may be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed by the Partnership, Parent and ET.

6. Waiver. No failure on the part of any party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy. No single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. No provision of this Agreement may be waived, discharged or terminated other than by an instrument in writing signed by the party against whom the enforcement of such waiver, discharge or termination is sought.

8. Entire Agreement. This Agreement constitutes the entire agreement between the three parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, both written and oral (excluding, for clarity, the Confidentiality Agreement and the Merger Agreement), between the parties with respect to the subject matter hereof.

9. Section Headings. Headings of the Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever.

10. Construction. (a) Each of the parties has participated in the drafting and negotiation of this Agreement. The parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement. (b) Whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders. (c) The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. (d) As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” (e) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement, unless the context otherwise requires. (f) The term “or” is not exclusive. (g) The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply “if.” (h) All accounting terms not expressly defined in this Agreement shall have the meanings given to them under GAAP. (i) When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. (j) Except as otherwise indicated, all references in this Agreement to “Sections,” “Exhibits” and “Schedules” are intended to refer to Sections of this Agreement and Exhibits or Schedules to this Agreement. (k) References to any statute, law or regulation shall be deemed to refer to such statute, law or regulation as amended from time to time and to any rules, regulations or requirements promulgated thereunder. (l) Unless otherwise specified in this Agreement, all references in this Agreement to “dollars” or “$” shall mean U.S. Dollars and all amounts in this Agreement shall be paid in U.S. Dollars, and if any amounts, costs, fees or expenses incurred by any Party pursuant to this Agreement are denominated in a currency other than U.S. Dollars, to the extent applicable, the U.S. Dollar equivalent for such costs, fees and expenses shall be determined by converting such other currency to U.S. Dollars at the foreign exchange rates published in The Wall Street Journal or, if not reported

10

thereby, another authoritative source in effect at the time such amount, cost, fee or expense is incurred, and if the resulting conversion yields a number that extends beyond two (2) decimal points, rounded to the nearest penny. (m) When calculating the period of time within which, or following which, any action is to be taken pursuant to this Agreement, the date that is the reference day in calculating such period shall be excluded. References to days shall refer to calendar days unless business days are specified.

11. Assignment. 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. Subject to the first sentence of this Section, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Any purported assignment not permitted under this Section shall be null and void.

12. Governing Law. This Agreement, and all claims or causes of action (whether at Law, in contract or in tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

13. Jurisdiction; Specific Enforcement.

(a) The parties agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed, or were threatened to be not performed, in accordance with their specific terms or were otherwise breached. 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 3(h) of this Agreement. The parties further agree that no party to this Agreement shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 13 and each party waives any objection to the imposition of such relief or any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. A party’s pursuit of an injunction, specific performance or other equitable remedies at any time shall not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such party may be entitled.

(b) Each of the parties hereto irrevocably agrees that any legal action or proceeding relating to or arising out of this Agreement and the rights and obligations hereunder, or for recognition and enforcement of any judgment relating to or arising out of this Agreement and the rights and obligations hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined 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

11

declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to or arising out of this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts in accordance with the first sentence of this Section 13(b). Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. To the fullest extent permitted by applicable Law, each of the parties hereto hereby consents to the service of process in accordance with Section 7; provided, however, that nothing herein shall affect the right of any party to serve legal process in any other manner permitted by Law.

14. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

15. 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.

16. Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the proposed transaction and the anticipated benefits thereof.

(“NuStar” or “NS”), that could cause actual results to differ materially from those expressed in such forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: the completion of the proposed transaction on anticipated terms and timing, or at all, including obtaining regulatory approvals and NuStar unitholder approval; anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, prospects, business and management strategies for the management, expansion and growth of the combined company’s operations, including the possibility that any of the anticipated benefits of the proposed transaction will not be realized or will not be realized within the expected time period; the ability of Sunoco and NuStar to integrate the business successfully and to achieve anticipated synergies and value creation; potential litigation relating to the proposed transaction that could be instituted against Sunoco, NuStar or the directors of their respective general partners; the risk that disruptions from the proposed transaction will harm Sunoco’s or NuStar’s business, including current plans and operations and that management’s time and attention will be diverted on transaction-related issues; potential adverse reactions or changes to business relationships, including with employees, suppliers, customers, competitors or credit rating agencies, resulting from the announcement or completion of the proposed transaction; rating agency actions and Sunoco and NuStar’s ability to access short-and long-term debt markets on a timely and affordable basis; potential business uncertainty, including the outcome of commercial negotiations and changes to existing business relationships during the pendency of the proposed transaction that could affect Sunoco’s and/or NuStar’s financial performance and operating results; certain restrictions during the pendency of the merger that may impact NuStar’s ability to pursue certain business opportunities or strategic transactions or otherwise operate its business; dilution caused by Sunoco’s issuance of additional units representing limited partner interests in connection with the proposed transaction; fees, costs and expenses and the possibility that the transaction may be more expensive to complete than anticipated; those risks described in Item 1A of Sunoco’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission (the “SEC”) on February 17, 2023, and its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K; those risks described in Item 1A of NuStar’s Annual Report on Form 10-K, filed with the SEC on February 23, 2023, and its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K; and those risks that will be more fully described in the registration statement on Form S-4 and accompanying proxy statement/prospectus that will be filed with the SEC in connection with the proposed transaction. Those disclosures are incorporated by reference in this presentation. While the list of factors presented here is, and the list of factors to be presented in the registration statement and the proxy statement/prospectus will be, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of
