At the Effective Time, the books and records of ▇▇▇▇▇▇ shall be revised to reflect the admission of Partners as the sole limited partner of ▇▇▇▇▇▇ and all other limited partners of ▇▇▇▇▇▇ simultaneously ceasing to be limited partners of ▇▇▇▇▇▇ pursuant to the terms of this Agreement, and ▇▇▇▇▇▇ shall continue without dissolution.

(c) Each ▇▇▇▇▇▇ Common Unit issued and outstanding immediately prior to the Effective Time (other than any ▇▇▇▇▇▇ Common Units held by ▇▇▇▇▇▇ or its Subsidiaries, which shall be cancelled as of the Effective Time) shall be converted into the right to receive 1.010 Partners Common Units (such ratio, the “Exchange Ratio,” and such amount of Partners Common Units, the “Merger Consideration”) which Partners Common Units shall be duly authorized and validly issued in accordance with applicable Laws and the Partners Partnership Agreement, as applicable, fully paid (to the extent required under the Partners Partnership Agreement) and non-assessable (except to the extent such non-assessability may be affected by Sections 17-303, 17-607 and 17-804 of the DRULPA) (such Partners Common Units described in this clause (c) shall be referred to herein as the “New Common Units”).

At the Effective Time, the unit transfer books of ▇▇▇▇▇▇ shall be closed immediately and there shall be no further registration of transfers on the unit transfer books of ▇▇▇▇▇▇ with respect to ▇▇▇▇▇▇ Common Units.

Section 3.4 Exchange of Certificates.

(a) Exchange Agent. Promptly after the Effective Time, Partners shall deposit or shall cause to be deposited with the Exchange Agent for the benefit of the holders of ▇▇▇▇▇▇ Common Units, for exchange in accordance with this Article III, through the Exchange Agent, New Common Units and cash as required by this Article III. Partners agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 3.2 and Section 3.4(c) and to make payments in lieu of any fractional New Common Units pursuant to Section 3.4(e), in each case without interest. Any cash and New Common Units deposited with the Exchange Agent (including as payment for any fractional New Common Units in accordance with Section 3.4(e) and any distributions with respect to such fractional New Common Units in accordance with Section 3.4(c)) shall hereinafter be referred to as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for ▇▇▇▇▇▇ Common Units pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 3.4(c) and 3.4(e), the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Partners shall instruct the Exchange Agent to mail to each record holder of ▇▇▇▇▇▇ Common Units as of the Effective Time (i) a letter of transmittal (which shall specify that in respect of certificated ▇▇▇▇▇▇ Common Units, delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which shall be in customary form and agreed to by Partners and ▇▇▇▇▇▇ prior to the Effective Time) and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration payable in respect of ▇▇▇▇▇▇ Common Units represented by such

Certificates or Book-Entry Units, as applicable. Promptly after the Effective Time, upon surrender of Certificates, if any, for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents (including in respect of Book-Entry Units) as may be required pursuant to such instructions, each holder who held ▇▇▇▇▇▇ Common Units immediately prior to the Effective Time shall be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor (A) New Common Units representing, in the aggregate, the whole number of New Common Units that such holder has the right to receive pursuant to this Article III (after taking into account all ▇▇▇▇▇▇ Common Units then held by such holder) and (B) a check in an amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to this Article III, including cash payable in lieu of any fractional New Common Units pursuant to Section 3.4(e) and distributions pursuant to Section 3.4(c). No interest shall be paid or accrued on any Merger Consideration, any cash payment in lieu of fractional New Common Units, or on any unpaid distributions payable to holders of Certificates or Book-Entry Units. In the event of a transfer of ownership of ▇▇▇▇▇▇ Common Units that is not registered in the transfer records of ▇▇▇▇▇▇, the Merger Consideration payable in respect of such ▇▇▇▇▇▇ Common Units may be paid to a transferee, if the Certificate representing such ▇▇▇▇▇▇ Common Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both certificated and book-entry ▇▇▇▇▇▇ Common Units, accompanied by all documents required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such ▇▇▇▇▇▇ Common Units, or shall establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until the required documentation has been delivered and Certificates, if any, have been surrendered, as contemplated by this Section 3.4, each Certificate or Book-Entry Unit shall be deemed at any time after the Effective Time to represent only the right to receive upon such delivery and surrender the Merger Consideration payable in respect of ▇▇▇▇▇▇ Common Units and any cash or distributions to which such holder is entitled pursuant to Section 3.2.

(c) Distributions with Respect to Unexchanged ▇▇▇▇▇▇ Common Units. No distributions declared or made with respect to Partners Common Units with a record date after the Effective Time shall be paid to the holder of any ▇▇▇▇▇▇ Common Units with respect to New Common Units that such holder would be entitled to receive in accordance herewith and no cash payment in lieu of fractional New Common Units shall be paid to any such holder until such holder shall have delivered the required documentation and surrendered any Certificates or Book-Entry Units as contemplated by this Section 3.4. Subject to applicable Law, following compliance with the requirements of Section 3.4(b), there shall be paid to such holder of New Common Units issuable in exchange therefor, without interest, (i) promptly after the time of such compliance, the amount of any cash payable in lieu of fractional New Common Units to which such holder is entitled pursuant to Section 3.4(e) and the amount of distributions with a record date after the Effective Time theretofore paid with respect to New Common Units and payable with respect to such New Common Units, and (ii)at the appropriate payment date, the amount of distributions with a record date after the Effective Time but prior to such delivery and surrender and a payment date subsequent to such compliance payable with respect to such New Common Units.

(d) Further Rights in ▇▇▇▇▇▇ Common Units. The Merger Consideration issued upon conversion of a ▇▇▇▇▇▇ Common Unit in accordance with the terms hereof (including any cash paid pursuant to Section 3.2, Section 3.4(c) or Section 3.4(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such ▇▇▇▇▇▇ Common Unit.

(e) Fractional New Common Units. No certificates or scrip of New Common Units representing fractional New Common Units or book entry credit of the same shall be issued upon the surrender of ▇▇▇▇▇▇ Common Units outstanding immediately prior to the Effective Time in accordance with Section 3.4(b), and such fractional interests will not entitle the owner thereof to vote or to have any rights as a holder of any New Common Units. Notwithstanding any other provision of this Agreement, each holder of ▇▇▇▇▇▇ Common Units converted in the Merger who would otherwise have been entitled to receive a fraction of a New Common Unit (after taking into account all ▇▇▇▇▇▇ Common Units exchanged by such holder) shall receive, in lieu thereof, cash (without interest rounded up to the nearest whole cent) in an amount equal to the product of (i) the Average Closing Price as of the Closing Date and (ii) the fraction of a New Common Unit that such holder would otherwise be entitled to receive pursuant to this Article III. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall so notify Partners, and Partners shall, or shall cause the Surviving Entity to, deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof. To the extent applicable, each holder of ▇▇▇▇▇▇ Common Units shall be deemed to have consented for U.S. federal income tax purposes (and to the extent applicable, state or local income tax purposes) to report the cash received for fractional New Common Units in the Merger as a sale of a portion of the holder’s Duncan Common Units to Partners consistent with Treasury Regulation Section 1.708-1(c)(4).

(f) Termination of Exchange Fund. Any portion of the Exchange Fund constituting New Common Units or cash that remains undistributed to the holders of ▇▇▇▇▇▇ Common Units after 180 days following the Effective Time shall be delivered to Partners upon demand by Partners and, from and after such delivery, any former holders of ▇▇▇▇▇▇ Common Units who have not theretofore complied with this Article III shall thereafter look only to Partners for the Merger Consideration payable in respect of such ▇▇▇▇▇▇ Common Units, any cash in lieu of fractional New Common Units to which they are entitled pursuant to Section 3.4(e) and any distributions with respect to New Common Units to which they are entitled pursuant to Section 3.4(c), in each case, without any interest thereon. Any amounts remaining unclaimed by holders of ▇▇▇▇▇▇ Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any governmental entity shall, to the extent permitted by applicable Law, become the property of Partners, free and clear of any Liens, claims or interest of any Person previously entitled thereto.

(g) No Liability. To the fullest extent permitted by Law, none of ▇▇▇▇▇▇ ▇▇, Partners, ▇▇▇▇▇▇, or the Surviving Entity shall be liable to any holder of ▇▇▇▇▇▇ Common Units for any Partners Common Units (or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or

destroyed and, if required by Partners, the posting by such Person of a bond, in such reasonable amount as Partners may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of ▇▇▇▇▇▇ Common Units represented by such Certificate and any distributions to which the holders thereof are entitled pursuant to Section 3.3.

(i) Withholding. Each of Partners, the Surviving Entity and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of ▇▇▇▇▇▇ Common Units such amounts as Partners, the Surviving Entity or the Exchange Agent is required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment; provided, however, that Partners, the Surviving Entity or the Exchange Agent, as the case may be, shall provide reasonable notice to the applicable holders of ▇▇▇▇▇▇ Common Units prior to withholding any amounts pursuant to this Section 3.4(i). To the extent that amounts are so deducted and withheld by Partners, the Surviving Entity or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of ▇▇▇▇▇▇ Common Units in respect of whom such deduction and withholding was made by Partners, the Surviving Entity or the Exchange Agent, as the case may be.

(j) Book Entry and Admission of Holders of New Common Units as Additional Limited Partners of Partners. All New Common Units to be issued in the Merger shall be issued in book-entry form, without physical certificates. Upon the issuance of New Common Units to the holders of ▇▇▇▇▇▇ Common Units in accordance with this Section 3.4 and the compliance by such holders with the requirements of Section 10.4 of the Partners Partnership Agreement, which requirements may be satisfied by each holder of ▇▇▇▇▇▇ Common Units by the execution and delivery by such holder of a completed and executed letter of transmittal, Partners GP shall be deemed to have automatically consented to the admission of such holder as a limited partner of Partners in respect of its New Common Units and shall reflect such admission on the books and records of Partners.

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

Section 3.5 Anti-Dilution Provisions. In the event of any subdivisions, reclassifications, recapitalizations, splits, unit distributions, combinations or exchange of units with respect to, or Rights in respect of, ▇▇▇▇▇▇ Common Units or Partners Common Units (in each case, as permitted pursuant to Section 4.3), the number of New Common Units to be issued in the Merger and the Average Closing Price of Partners Common Units will be correspondingly adjusted to provide to the holders of ▇▇▇▇▇▇ Common Units the same economic effect as contemplated by this Agreement prior to such event.

Section 3.6 Treatment of ▇▇▇▇▇▇ Equity-Based Awards; ▇▇▇▇▇▇ Unit Purchase Plan.

(a) As of the date of this Agreement, there are no outstanding unvested restricted ▇▇▇▇▇▇ Common Units, and there are no outstanding unit appreciation rights or options or other awards issued under the ▇▇▇▇▇▇ Unit Plan.

(b) With respect to the ▇▇▇▇▇▇ Unit Purchase Plan, the amount of money credited to the account of each participant under such plan, after reduction for any required withholding, and held (immediately prior to the Effective Time) for the purchase of ▇▇▇▇▇▇ Common Units (including, but not limited to, each participant’s accumulated payroll deductions for the DUPP Purchase Period during which the Effective Time occurs plus the applicable Employee Discount Amount, as defined in and determined under the ▇▇▇▇▇▇ Unit Purchase Plan, with respect thereto) shall be used to purchase ▇▇▇▇▇▇ Common Units immediately prior to the Effective Time in accordance with the terms of the ▇▇▇▇▇▇ Unit Purchase Plan. At the Effective Time, automatically and without any action on the part of any participant in the ▇▇▇▇▇▇ Unit Purchase Plan, each whole ▇▇▇▇▇▇ Common Unit then credited to the account of each participant, whether purchased under the ▇▇▇▇▇▇ Unit Purchase Plan for a DUPP Purchase Period ended prior to the Effective Time or purchased in accordance with this Section 3.6(b) or otherwise, shall be canceled at the Effective Time and converted into the right to receive the Merger Consideration pursuant to Section 3.1(c). Any fractional ▇▇▇▇▇▇ Common Unit credited to the account of a participant and not converted to the right to receive Merger Consideration in accordance with the foregoing shall be converted into the right to receive cash in accordance with the applicable provisions of the ▇▇▇▇▇▇ Unit Purchase Plan and Section 3.4(b). The conversion of the ▇▇▇▇▇▇ Common Units pursuant to this Section 3.6(b) shall be in full satisfaction of the obligations of ▇▇▇▇▇▇ under the ▇▇▇▇▇▇ Unit Purchase Plan with respect to the DUPP Purchase Period in which the Effective Time falls and with respect to all prior DUPP Purchase Periods. ▇▇▇▇▇▇ shall cause the ▇▇▇▇▇▇ Unit Purchase Plan to be suspended as of the Effective Time, and no further purchase rights shall be granted or exercised under the ▇▇▇▇▇▇ Unit Purchase Plan unless and until such suspension is lifted in accordance with the terms of such Plan and Section 3.6(c).

(c) As soon as practicable following the suspension of the ▇▇▇▇▇▇ Unit Purchase Plan in accordance with Section 3.6(b), if permitted under the NYSE corporate governance rules with respect to shareholder approval of equity compensation plans and amendments thereto and any other applicable Law without seeking approval of the holders of the Partners Common Units or the ▇▇▇▇▇▇ Common Units or the imposition of any other condition (other than compliance with applicable Securities Act requirements), (i) the ▇▇▇▇▇▇ Unit Purchase Plan shall be continued by EPCO and all ▇▇▇▇▇▇ obligations assumed by Partners and such plan shall continue in effect, subject to amendment, termination and/or suspension in accordance with its terms, notwithstanding the occurrence of the Merger, (ii) from and after the Effective Time all references to ▇▇▇▇▇▇ Common Units in the ▇▇▇▇▇▇ Unit Purchase Plan shall be substituted with references to Partners Common Units, (iii) the number of Partners Common Units that will be available for delivery under the ▇▇▇▇▇▇ Unit Purchase Plan from and after the Effective Time shall equal the number of ▇▇▇▇▇▇ Common Units that were available for delivery under the ▇▇▇▇▇▇ Unit Purchase Plan immediately prior to the Effective Time (but after effecting the purchases described in Section 3.6(b) multiplied by the Exchange Ratio (rounded down to the nearest whole number of Partners Common Units), and (iv) no participant in the ▇▇▇▇▇▇ ▇▇▇▇

▇▇

▇▇▇▇▇▇▇▇ ▇▇▇▇ shall have any right to acquire ▇▇▇▇▇▇ Common Units under such plan from and after the Effective Time.

(d) If the continuation of the ▇▇▇▇▇▇ Unit Purchase Plan in accordance with the provisions of Section 3.6(c) is not permitted, ▇▇▇▇▇▇ shall cause the ▇▇▇▇▇▇ Unit Purchase Plan to terminate as of the Effective Time, and no further purchase rights shall be granted or exercised under the ▇▇▇▇▇▇ Unit Purchase Plan at or after the Effective Time.

Notwithstanding the foregoing, nothing contained in this Agreement shall prohibit ▇▇▇▇▇▇ or any of its Representatives from furnishing any information or data pertaining to ▇▇▇▇▇▇, or entering into or participating in discussions or negotiations with, any person that makes an unsolicited written Acquisition Proposal that did not result from a knowing and intentional breach of this Section 6.6 (a “Receiving Party”), if (i) the ▇▇▇▇▇▇ Audit Committee after consultation with its outside legal counsel and financial advisors, determines in good faith (A) that such Acquisition Proposal constitutes or is likely to result in a Superior Proposal, and (B) that failure to take such action would be inconsistent with its duties under the ▇▇▇▇▇▇ Existing Partnership Agreement and applicable Law and (ii) prior to furnishing any such non-public information to such Receiving Party (including any information pertaining to ▇▇▇▇▇▇ Subsidiaries in which Partners has an equity interest or transactions to which Partners is a party), ▇▇▇▇▇▇ receives from such Receiving Party an executed Confidentiality Agreement.

(b) Except as otherwise provided in this Section 6.6(b), neither the ▇▇▇▇▇▇ Audit Committee nor the ▇▇▇▇▇▇ ▇▇ Board shall: (i) (A) withdraw, modify or qualify in any manner adverse to Partners the ▇▇▇▇▇▇ Recommendation or (B) publicly approve or recommend, or publicly propose to approve or recommend, any Acquisition Proposal (any action described in this clause (i) being referred to as a “▇▇▇▇▇▇ Change in Recommendation”); or (ii) approve, adopt or recommend, or publicly propose to approve, adopt or recommend, or allow ▇▇▇▇▇▇ or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement, or other similar contract or any tender or exchange offer providing for, with respect to, or in connection with, any Acquisition Proposal. Notwithstanding the foregoing, at any time prior to obtaining the ▇▇▇▇▇▇ Unitholder Approval, the ▇▇▇▇▇▇ Audit Committee may make a ▇▇▇▇▇▇ Change in Recommendation if it has concluded in good faith, after consultation with its outside legal counsel and financial advisors, that failure to make a ▇▇▇▇▇▇ Change in Recommendation would be inconsistent with its duties under the ▇▇▇▇▇▇ Existing Partnership Agreement and applicable Law; provided, however, that (1) the ▇▇▇▇▇▇ Audit Committee shall not be entitled to exercise its right to make a ▇▇▇▇▇▇ Change in Recommendation pursuant to this sentence unless ▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇ have: (w) complied in all material respects with this Section 6.6, (x) provided to Partners and the Partners Audit Committee three Business Days prior written notice (such notice, a “Notice of Proposed Recommendation Change”) advising Partners that the ▇▇▇▇▇▇ ▇▇ Audit Committee intends to take such action and specifying the reasons therefor in reasonable detail, including, if applicable, the terms and conditions of any Superior Proposal that is the basis of the proposed action and the identity of the Person making the proposal (it being understood and agreed that

any amendment to the terms of any such Superior Proposal shall require a new Notice of Proposed Recommendation Change and an additional three Business Day period) and (y) if applicable, provided to Partners all materials and information delivered or made available to the Person or group of persons making any Superior Proposal in connection with such Superior Proposal (to the extent not previously provided) and (2) the ▇▇▇▇▇▇ Audit Committee shall not be entitled to make a ▇▇▇▇▇▇ Change in Recommendation in response to an Acquisition Proposal unless such Acquisition Proposal constitutes a Superior Proposal. Any ▇▇▇▇▇▇ Change in Recommendation shall not invalidate the approval of this Agreement or any other approval of the ▇▇▇▇▇▇ Audit Committee, including in any respect that would have the effect of causing any state (including Delaware) corporate takeover statute or other similar statute to be applicable to the transactions contemplated hereby or thereby, including the Merger. Notwithstanding any provision in this Agreement to the contrary, Partners and Partners GP shall maintain, and cause their Representatives to maintain, the confidentiality of all information received from ▇▇▇▇▇▇ pursuant to this Section 6.6, subject to the exceptions contained in the Confidentiality Agreement.

(c) In addition to the obligations of ▇▇▇▇▇▇ set forth in this Section 6.6, ▇▇▇▇▇▇ shall as promptly as practicable (and in any event within 24 hours after receipt) advise Partners orally and in writing of any Acquisition Proposal or any matter giving rise to a ▇▇▇▇▇▇ Change in Recommendation and the material terms and conditions of any such Acquisition Proposal or any matter giving rise to a ▇▇▇▇▇▇ Change in Recommendation (including any changes thereto) and the identity of the Person making any such Acquisition Proposal. ▇▇▇▇▇▇ shall keep Partners informed on a reasonably current basis of material developments with respect to any such Acquisition Proposal or any matter giving rise to a ▇▇▇▇▇▇ Change in Recommendation.

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

Section 6.7 Affiliate Arrangements.

(a) Not later than the 15th day after the mailing of the Proxy Statement/Prospectus, ▇▇▇▇▇▇ shall deliver to Partners a schedule listing each person that, to the best of its knowledge, is or is reasonably likely to be, as of the date of the ▇▇▇▇▇▇ Meeting, deemed to be an “affiliate” of ▇▇▇▇▇▇ (a “Rule 145 Affiliate”) as that term is used in Rule 145 under the Securities Act.

(b) ▇▇▇▇▇▇ shall use its commercially reasonable best efforts to cause its Rule 145 Affiliates not to sell any securities received under the Merger in violation of the registration requirements of the Securities Act, including Rule 145 thereunder.

Section 6.8 Takeover Laws. Neither ▇▇▇▇▇▇ nor Partners shall take any action that would cause the transactions contemplated by this Agreement to be subject to requirements imposed by any Takeover Laws, and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement from, or if necessary challenge the validity or applicability of, any rights plan adopted by such party or any applicable Takeover Law, as now or hereafter in effect, including Takeover Laws of any state that purport to apply to this Agreement or the transactions contemplated hereby.

Section 6.9 No Rights Triggered. Each of ▇▇▇▇▇▇ and Partners shall take all steps necessary to ensure that the entering into of this Agreement and the consummation of the transactions contemplated hereby and any other action or combination of actions, or any other transactions contemplated hereby, do not and will not result in the grant of any Rights to any person (a) in the case of ▇▇▇▇▇▇, under the ▇▇▇▇▇▇ Existing Partnership Agreement, and, in the case of Partners, under the Partners Partnership Agreement or (b) under any material agreement to which it or any of its Subsidiaries is a party.

Section 6.10 New Common Units Listed. Partners shall use its commercially reasonable best efforts to list, prior to the Closing, on the NYSE, upon official notice of issuance, the New Common Units.

Section 6.11 Third-Party Approvals.

(a) Partners and ▇▇▇▇▇▇ and their respective Subsidiaries shall cooperate and use their respective commercially reasonable best efforts to prepare all documentation, to effect all filings, to obtain all permits, consents, approvals and authorizations of all Governmental Authorities and third parties necessary to consummate the transactions contemplated by this Agreement and to comply with the terms and conditions of such permits, consents, approvals and authorizations and to cause the Merger to be consummated as expeditiously as practicable. Each of Partners and ▇▇▇▇▇▇ shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable Laws relating to the exchange of information, with respect to, all material written information submitted to any third party or any Governmental Authorities in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and promptly. Each party hereto agrees that it will consult with the Other Parties with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement, and each party will keep the Other Parties apprised of the status of material matters relating to completion of the transactions contemplated hereby.

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

Section 6.12 Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any additional rights that any director, officer, trustee, employee, agent, or fiduciary may have under any employment or indemnification agreement or under the ▇▇▇▇▇▇ Existing Partnership Agreement, the ▇▇▇▇▇▇ ▇▇ Existing LLC Agreement, or this Agreement or, if applicable, similar organizational documents or agreements of any of ▇▇▇▇▇▇’▇ Subsidiaries, from and after the Effective Time, Partners GP, Partners and the Surviving Entity, jointly and severally, shall: (i) indemnify and hold harmless each person who is at the date hereof or during the period from the date hereof through the date of the Effective Time serving as a director or officer of ▇▇▇▇▇▇ ▇▇ or of any of its Subsidiaries or as a trustee of (or in a similar capacity with) any Compensation and Benefit Plan of any thereof (collectively, the “Indemnified Parties”) to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, in connection with any Claim and any losses, claims, damages, liabilities, costs, Indemnification Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) resulting therefrom; and (ii) promptly pay on behalf of or, within 10 days after any request for advancement, advance to each of the Indemnified Parties, any Indemnification Expenses incurred in defending, serving as a witness with respect to or otherwise participating with respect to any Claim in advance of the final disposition of such Claim, including payment on behalf of or advancement to the Indemnified Party of any Indemnification Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security. The indemnification and advancement obligations of Partners and the Surviving Entity pursuant to this Section 6.12(a) shall extend to acts or omissions occurring at or before the Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger and the transactions contemplated by this Agreement, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto), and all rights to indemnification and advancement conferred hereunder shall continue as to any Indemnified Party who has ceased to be a director or officer of ▇▇▇▇▇▇ ▇▇ after the date hereof and shall inure to the benefit of such person’s heirs, executors and personal and legal representatives. As used in this Section 6.12(a): (x) the term “Claim” means any threatened, asserted, pending or completed action, whether instituted by any party hereto, any Governmental Authority or any other person, that any Indemnified Party in good faith believes might lead to the institution of any action or proceeding, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism (“Action”), arising out of or pertaining to matters that relate to such Indemnified Party’s duties or service as a director or officer of ▇▇▇▇▇▇ ▇▇ or of any of its Subsidiaries or as a trustee of (or in a similar capacity with) any Compensation and Benefit Plan of any thereof; and (y) the term “Indemnification Expenses” means reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim for which indemnification is authorized pursuant to this Section 6.12(a), including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party. Neither Partners, ▇▇▇▇▇▇ ▇▇ nor the Surviving Entity shall

settle, compromise or consent to the entry of any judgment in any actual or threatened Action in respect of which indemnification has been or could be sought by such Indemnified Party hereunder unless such settlement, compromise or judgment includes an unconditional release of such Indemnified Party from all liability arising out of such Action without admission or finding of wrongdoing, or such Indemnified Party otherwise consents thereto.

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

(c) For a period of six years from the Effective Time, the ▇▇▇▇▇▇ agreement of limited partnership shall contain provisions no less favorable with respect to indemnification, advancement of expenses and limitations on liability of directors and officers than are set forth in the ▇▇▇▇▇▇ Existing Partnership Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were Indemnified Parties, unless such modification shall be required by Law and then only to the minimum extent required by Law.

(d) For a period of six years from the Effective Time, Partners shall, or shall cause EPCO to, maintain in effect the current directors’ and officers’ liability insurance policies covering the Indemnified Parties maintained by EPCO (but may substitute therefor other policies of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the Indemnified Parties so long as that substitution does not result in gaps or lapses in coverage) with respect to matters occurring on or before the Effective Time, but neither Partners nor EPCO will be required to pay annual premiums in excess of 300% of the last annual premiums paid therefor prior to the date hereof and shall purchase as much coverage as is reasonably practicable for that amount if the coverage described in this Section 6.12(d) would cost in excess of that amount.

(e) If Partners, ▇▇▇▇▇▇ ▇▇, the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges with or into any other person and shall not be the continuing or surviving corporation, partnership or other entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of Partners, ▇▇▇▇▇▇ ▇▇ or the Surviving Entity assume the obligations set forth in this Section 6.12.

(f) Partners and ▇▇▇▇▇▇ ▇▇ shall cause the Surviving Entity to perform all of the obligations of the Surviving Entity under this Section 6.12.

(g) This Section 6.12 shall survive the consummation of the Merger and is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and the Indemnitees and their respective heirs and personal representatives, and shall be binding on Partners, ▇▇▇▇▇▇ ▇▇, the Surviving Entity and their respective successors and assigns.

Each of ▇▇▇▇▇▇ and Partners shall give prompt notice to the other of (a) any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein, and (b) (i) any change in its condition (financial or otherwise) or business or (ii) any litigation or governmental complaints, investigations or hearings, in each case to the extent such change, litigation, complaints, investigations, or hearings results in, or would reasonably be expected to result in, a Material Adverse Effect.

Section 6.14 Rule 16b-3. Prior to the Effective Time, (i) ▇▇▇▇▇▇ shall take such steps as may be reasonably requested by any party hereto to cause dispositions of ▇▇▇▇▇▇ equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of ▇▇▇▇▇▇ to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters and (ii) Partners shall take such steps as may be reasonably requested by any party hereto to cause dispositions of Partners equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of Partners to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters.

Each of ▇▇▇▇▇▇ ▇▇ and Partners GP shall consult with the Other Party regarding the declaration and payment of distributions in respect of the ▇▇▇▇▇▇ Common Units and the Partners Common Units and the record and payment dates relating thereto, so that no ▇▇▇▇▇▇ Unitholder shall receive two distributions, or fail to receive one

distribution, for any single calendar quarter with respect to its applicable ▇▇▇▇▇▇ Common Units or any Partners Common Units any such ▇▇▇▇▇▇ Unitholder receives in exchange therefor pursuant to the Merger.

Section 6.18 ▇▇▇▇▇▇ ▇▇ Amended and Restated Limited Liability Company Agreement. As of the Effective Time, the ▇▇▇▇▇▇ ▇▇ Existing LLC Agreement shall be amended and restated in substantially the form of the ▇▇▇▇▇▇ ▇▇ Amended and Restated LLC Agreement attached hereto as Annex A.

(a) By the mutual consent of Partners and ▇▇▇▇▇▇ in a written instrument.

(b) By either Partners or ▇▇▇▇▇▇ upon written notice to the other, if:

(i) any Governmental Authority has issued a statute, rule, order, decree or regulation or taken any other action, in each case permanently restraining, enjoining or otherwise prohibiting the consummation of the Merger or making the Merger illegal and such statute, rule, order, decree, regulation or other action shall have become final and nonappealable (provided that the terminating party is not then in breach of Section 6.1);

a Delaware limited liability company

Address
▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇
▇▇▇▇▇ ▇▇▇▇
▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇

8. Limited Liability. Except as otherwise provided by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Member shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a member of the Company.

9. Capital Contributions. The Member may make capital contributions to the Company, in cash, property or other assets as the Member in its sole discretion shall determine from time to time, but shall have no obligation to do so.

10. Allocation of Profits and Losses. The Company’s profits and losses shall be allocated solely to the Member.

11. Distributions. Distributions shall be made to the Member at the times and in the aggregate amounts determined by the Member. Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to the Member on account of its interest in the Company if such distribution would violate Section 18-607 of the Act or other applicable Law. “Law” means any applicable constitutional provision, statute, act, code, law, regulation, rule, ordinance, order, decree, ruling, proclamation, resolution, judgment, decision, declaration or interpretative or advisory opinion or letter of a governmental authority.

12. Management. The management of the Company shall be exclusively vested in a Board of Directors (the “Board” or “Board of Directors”) and, subject to the direction of the Board, the officers (the “Officers”), who shall collectively (Board and Officers) constitute “managers” of the Company within the meaning of the Act. The authority and functions of the Board on the one hand and of the Officers on the other shall be identical to the activity and functions of the board of directors and officers, respectively, of a corporation organized under the Delaware General Corporation Law. Thus, the business and affairs of the Company shall be managed by the Board, and the day-to-day activities of

Page 3 of 9

the Company shall be conducted on the Company’s behalf by the Officers, who shall be agents of the Company.

13. Board of Directors. The Board shall consist of one or more individuals (the ”Directors”) appointed by the Member, such number of Directors to be determined from time to time by the Member.

The Directors shall hold office until their respective successors are chosen and qualify or until their earlier death, resignation or until removed by the Member, in the Member’s discretion. The Board may act (a) by majority vote of Directors present at a meeting at which a quorum (consisting of a majority of Directors) is present or (b) by written consent of a majority of the Directors.

14. Officers. The Board may, from time to time as it deems advisable, select natural persons, who shall be agents of the Company, and designate them as Officers of the Company and assign titles (including, without limitation, Chairman, President, Vice President, Secretary, Treasurer, Assistant Secretary and Assistant Treasurer) to any such person. Unless the Board decides otherwise, if the title is one commonly used for officers of a business corporation formed under the Delaware General Corporation Law, the assignment of such title shall constitute the delegation to such person of the authorities and duties that are normally associated with that office. Any delegation pursuant to this Section 14 may be revoked at any time by the Board. An Officer may be removed with or without cause by the Board.

15. Other Business. The Member may engage in or possess an interest in other business ventures of every kind and description, independently or with others. The Company shall not have any rights in or to such independent ventures or the income or profits therefrom by virtue of this Agreement.

16. Indemnification.

(a) To the fullest extent permitted by Law but subject to the limitations expressly provided in this Agreement, each Indemnitee (as defined below) shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities (joint or several), expenses (including reasonable legal fees and expenses), judgments, fines, penalties, interest, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any such person may be involved, or is threatened to be involved, as a party or otherwise, by reason of such person’s status as (i) a present or former member of the Board of Directors or any committee thereof, (ii) a present or former Member, (iii) a present or former Officer, or (iv) a Person serving at the request of the Company in another entity in a similar capacity as that referred to in the immediately preceding clauses (i) or (iii), provided, that the Person described in the immediately preceding clauses (i), (ii), (iii) or (iv) (“Indemnitee”) shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect

Page 4 of 9

of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 16, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 16 shall be made only out of the assets of the Company.

(b) To the fullest extent permitted by Law, expenses (including reasonable legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 16(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 16.

(c) The indemnification provided by this Section 16 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, as a matter of Law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity.

(d) The Company may purchase and maintain insurance, on behalf of the members of the Board of Directors, the Officers and such other persons as the Board of Directors shall determine, against any liability that may be asserted against or expense that may be incurred by such person in connection with the Company’s activities or such person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 16, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by the Indemnitee of such Indemnitee’s duties to the Company also imposes duties on, or otherwise involves services by, the Indemnitee to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable Law shall constitute “fines” within the meaning of Section 16; and action taken or omitted by the Indemnitee with respect to an employee benefit plan in the performance of such Indemnitee’s duties for a purpose reasonably believed by such Indemnitee to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Company.

(f) In no event may an Indemnitee subject any Members of the Company to personal liability by reason of the indemnification provisions of this Agreement.

Page 5 of 9

(g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 16 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(h) The provisions of this Section 16 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i) No amendment, modification or repeal of this Section 16 or any provision hereof shall in any manner terminate, reduce or impair either the right of any past, present or future Indemnitee to be indemnified by the Company or the obligation of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 16 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted, and provided such Person became an Indemnitee hereunder prior to such amendment, modification or repeal.

(j) THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 16 ARE INTENDED BY THE PARTIES TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT.

17. Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Company, the Members or any other Person for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered in a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b) Subject to its obligations and duties as set forth in Sections 12 and 13, the Board of Directors and any committee thereof may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through the Company’s Officers or agents, and neither the Board of Directors nor any committee thereof shall be responsible for any misconduct or negligence on the part of any such Officer or agent appointed by the Board of Directors or any committee thereof in good faith.

Page 6 of 9

provision hereof shall be prospective only and shall not in any way affect the limitations on liability under this Section 17 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may be asserted.

18. Assignments. The Member may at any time assign in whole or in part its limited liability company interest in the Company. If the Member transfers all of its interest in the Company pursuant to this Section 18, the transferee shall be admitted to the Company upon its execution of an instrument signifying its agreement to be bound by the terms and conditions of this Agreement. Such admission shall be deemed effective immediately prior to the transfer, and, immediately following such admission, the transferor Member shall cease to be a member of the Company.

19. Resignation. The Member may at any time resign from the Company. If the Member resigns pursuant to this Section 19, an additional member shall be admitted to the Company, subject to Section 20 hereof, upon its execution of an instrument signifying its agreement to be bound by the terms and conditions of this Agreement. Such admission shall be deemed effective immediately prior to the resignation, and, immediately following such admission, the resigning Member shall cease to be a member of the Company.

20. Admission of Additional Members. One or more additional members of the Company may be admitted to the Company with the written consent of the Member.

21. Dissolution.

(a) The Company shall dissolve and its affairs shall be wound up upon the first to occur of the following: (i) the written consent of the Member; (ii) at any time there are no members of the Company unless, within 90 days of the occurrence of the event that terminated the continued membership of the last remaining member of the Company (the “Termination Event”), the personal representative of the last remaining member agrees in writing to continue the Company and to the admission to the Company of such personal representative or its nominee or designee as a Member, effective as of the occurrence of the Termination Event, and such successor or its nominee or designee shall be admitted upon its execution of an instrument signifying its agreement to be bound by the terms and conditions of this Agreement; or (iii) the entry of a decree of judicial dissolution under Section 18-802 of the Act.

(b) The bankruptcy of the Member shall not cause the Member to cease to be a member of the Company and upon the occurrence of such an event, the business of the Company shall continue without dissolution.

(c) In the event of dissolution, the Company shall conduct only such activities as are necessary to wind up its affairs (including the sale of the assets of the Company in an orderly manner), and the assets of the Company shall be applied in the manner, and in the order of priority, set forth in Section 18-804 of the Act.

22. Severability of Provisions. Each provision of this Agreement shall be considered severable, and if for any reason any provision or provisions herein are determined to be invalid, unenforceable or illegal under any existing or future Law, such invalidity, unenforceability or illegality shall not impair the operation of or affect those portions of this Agreement that are valid, enforceable and legal.

23. Entire Agreement; Interpretation Under the Act. This Agreement constitutes the entire agreement of the Member with respect to the subject matter hereof. In the event of a direct conflict between the provisions of this Agreement and (a) any provision of the Certificate of Formation, or (b) any mandatory, non-waivable provision of the Act, such provision of the Certificate of Formation or the Act shall control. If any provision of the Act provides that it may be varied or superseded in the limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter.

24. Governing Law. THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER JURISDICTION.

25. Amendments. This Agreement may not be modified, altered, supplemented or amended except pursuant to a written agreement executed and delivered by the Member.

26. Sole Benefit of Member. The provisions of this Agreement (including Section 8) are intended solely to benefit the Member and, to the fullest extent permitted by applicable Law, shall not be construed as conferring any benefit upon any creditor of the Company (and no such creditor shall be a third-party beneficiary of this Agreement), and no Member shall have any duty or obligation to any creditor of the Company to make any contributions or payments to the Company.

Any indemnification pursuant to this Section 9.1 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

(e) For purposes of this Section 9.1, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, the Indemnitee to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable Law shall constitute “fines” within the meaning of Section 9.1(a); and action taken or omitted by the Indemnitee with respect to any employee benefit plan in the performance of such Indemnittee’s duties for a purpose reasonably believed by such Indemnitee to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Partnership.

(f) In no event may an Indemnitee subject the Limited Partner to personal liability by reason of the indemnification provisions set forth in this Agreement.

(j) THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 9.1 ARE INTENDED BY THE PARTIES TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT.

9.2 Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partner or any other Person for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered in a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b) Subject to its obligations and duties as General Partner set forth in Article V, the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

The provisions of this Agreement, to the extent that they restrict or otherwise modify the duties and liabilities of an Indemnitee otherwise existing at Law or in equity, are agreed by the Partners to replace such other duties and liabilities of such Indemnitee.

(d) Any amendment, modification or repeal of this Section 9.2 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability to the Partnership, the Limited Partner, the General Partner, and the Partnership’s and General Partner’s directors, officers and employees under this Section 9.2 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Notwithstanding any other provision of this Article 4, except subsection 4.2(b)(i), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain (as generally defined under Treas. Reg. § 1.704-1 or § 1.704-2), during any taxable year, any Partner who has a share of the Partner Nonrecourse Debt Minimum Gain shall be allocated such amount of income and gain for such year (and subsequent years, if necessary) determined in the manner required by Treas.

1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specifically allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Allocation Regulations, the deficit balance, if any, in its adjusted capital account created by such adjustments, allocations or distributions as quickly as possible.

(v) Gross Income Allocations. In the event any Partner has a deficit balance in its adjusted capital account at the end of any Partnership taxable period, such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this subsection 4.2(b)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its adjusted capital account after all other allocations provided in this Section 4.2 have been tentatively made as if subsection 4.2(b)(v) were not in the Agreement.

(ix) Curative Allocation. The special allocations set forth in subsections 4.2(b)(i), (ii) and (iv)-(vii) (the “Regulatory Allocations”) are intended to comply with the Allocation Regulations. Notwithstanding any other provisions of this Section 4.2, the Regulatory Allocations shall be taken into account in allocating items of income, gain, loss and deduction among the Partners such that, to the extent possible, the net amount of allocations of such items and the Regulatory Allocations to each Partner shall be equal to the net amount that would have been allocated to each Partner if the Regulatory Allocations had not occurred.

(c) Tax Allocations. For federal income tax purposes, except as otherwise required by the Code, the Allocation Regulations or the following sentence, each item of Partnership income, gain, loss, deduction and credit shall be allocated among the Partners in the same manner as corresponding items are allocated in Sections 4.2(a) and (b). Notwithstanding any provisions contained herein to the contrary, solely for federal income tax purposes, items of income, gain, depreciation, gain or loss with respect to property contributed or deemed contributed to the Partnership by a Partner shall be allocated so as to take into account the variation between the Partnership’s tax basis in such contributed property and its Carrying Value in the manner provided under Section 704(c) of the Code and Treas.

Partnership has committed prior to the date of termination and those costs, expenses, and liabilities shall be allocated to the distributee under this Section 7.2. The distribution of cash and/or property to a Partner in accordance with the provisions of this Section 7.2 constitutes a complete return to the Partner of its Capital Contributions and a complete distribution to the Partner of its Partnership Interest and all the Partnership’s property and constitutes a compromise to which all Partners have consented within the meaning of Section 17-502(b)(1) of the Delaware Act. To the extent that a Partner returns funds to the Partnership, it has no claim against any other Partner for those funds.

7.3 Termination. On completion of the distribution of Partnership assets as provided in this Agreement, the Partnership is terminated, and the General Partner (or such other Person or Persons as the Delaware Act may require or permit) shall cause the cancellation of the Certificate and any filings made as provided in Section 2.5 and shall take such other actions as may be necessary to terminate the Partnership.

(b) To the fullest extent permitted by Law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 9.1(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 9.1.

(f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

9.2 Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners or any other Person for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered in a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(d) Any amendment, modification or repeal of this Section 9.2 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability to the Partnership, the Limited Partners, the General Partner, and the Partnership’s and General Partner’s directors, officers and employees under this Section 9.2 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.
