Section 3.3 Rights As Unitholders; Unit Transfers.
 
  Except as set forth in Section 3.2, all ENP Common Units shall cease to be outstanding and shall automatically be canceled and cease to exist when converted as a result of and pursuant to the Merger.  At the Effective Time, each holder of a certificate representing ENP Common Units (a “Certificate”) and each holder of non-certificated ENP Common Units represented by book-entry (“Book-Entry Units”) shall cease to be a unitholder of ENP and cease to have any rights with respect thereto, except the right to receive (a) the Merger Consideration, and the right to be admitted as an Additional Member in connection therewith, (b) any cash to be paid in lieu of any fractional New Common Unit in accordance with Section 3.4(e), and (c) any distributions in accordance with Section 3.4(c), in each case, to be issued or paid, without interest, in consideration therefor in accordance with Section 3.4; provided, however, that the rights of (i)  any holder of ENP Restricted Units shall be as set forth in Section 3.1(e), (ii) VNG shall be as set forth in Section 3.2 and (iii) VNR and its Subsidiaries other than VNG, and ENP and its Subsidiaries shall be as set forth in Section 3.1(d).  In addition, to the extent applicable, holders of ENP Common Units immediately prior to the Effective Time shall have continued rights to any distribution, without interest, with respect to such ENP Common Units with a record date occurring prior to the Effective Time that may have been declared or made by ENP with respect to such ENP Common Units in accordance with the terms of this Agreement and which remains unpaid as of the Effective Time.  Such distributions by ENP are not part of the Merger Consideration, and shall be paid on the payment date set therefor to such holders of ENP Common Units whether or not they exchange their ENP Common Units pursuant to Section 3.4. At the Effective Time, except as set forth in Section 3.2, the unit transfer books of ENP shall be closed immediately and there shall be no further registration of transfers on the unit transfer books of ENP with respect to ENP Common Units.
 
Section 3.4 Exchange of Certificates.
 
(a) Exchange Agent.  Prior to the Effective Time, VNR shall appoint a commercial bank or trust company reasonably acceptable to ENP to act as exchange agent hereunder for the purpose of exchanging ENP Common Units for New Common Units and cash as required by this Article III (the “Exchange Agent”). Promptly after the Effective Time, VNR shall deposit, or shall cause a VNR Party to deposit, with the Exchange Agent for the benefit of the holders of the applicable ENP 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.  VNR agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 3.3 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 (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)) and New Common Units deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”  The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for ENP 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.
 
 
17

 
(b) Exchange Procedures.  Promptly after the Effective Time, VNR shall instruct the Exchange Agent to mail to each record holder of ENP Common Units as of the Effective Time (other than (x) holders of ENP Restricted Units, (y) VNG and (z) ENP and its Subsidiaries and VNR and its Subsidiaries other than VNG) (i) a letter of transmittal (which shall specify that in respect of certificated ENP 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 VNR and ENP prior to the Effective Time) (the “Letter of Transmittal”) and (ii) instructions (which shall be in customary form and agreed to by VNR and ENP prior to the Effective Time) for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration payable in respect of ENP 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 ENP Common Units immediately prior to the Effective Time (other than (x) holders of ENP Restricted Units, (y) VNG and (z) ENP and its Subsidiaries and VNR and its Subsidiaries other than VNG) 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 ENP 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 any VNR distributions payable pursuant to Section 3.4(c).  In the event of a transfer of ownership of ENP Common Units that is not registered in the transfer records of ENP, the Merger Consideration payable in respect of such ENP Common Units may be paid to a transferee, if the Certificate representing such ENP 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 ENP Common Units, accompanied by all documents reasonably required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such ENP Common Units, or shall establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable.  Until such required documentation has been delivered and Certificates, if any, have been surrendered, as contemplated by this Section 3.4, 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 ENP Common Units, cash payable in lieu of fractional New Common Units, distributions pursuant to Section 3.4(c), and (without the necessity of such surrender) any cash or distributions to which such holder is entitled pursuant to Section 3.3.
 
 
18

 
(c) Distributions with Respect to Unexchanged ENP Common Units.  No distributions declared or made with respect to VNR Common Units with a record date after the Effective Time shall be paid to the holder of any ENP 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 ENP Common Units.  The Merger Consideration issued upon conversion of an ENP Common Unit in accordance with the terms hereof (including any cash paid pursuant to Section 3.3, Section 3.4(c) or Section 3.4(e)) and any declared distributions to be paid on ENP Common Units as described in Section 3.3 shall be deemed to have been issued in full satisfaction of all rights pertaining to such ENP 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 ENP 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 ENP 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 ENP 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 VNR, and VNR shall 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 ENP 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 ENP Common Units to VNR consistent with Treasury Regulation Section 1.708-1(c)(4).
 
 
19

 
(f) Termination of Exchange Fund.  Any portion of the Exchange Fund constituting New Common Units or cash that remains undistributed to the holders of ENP Common Units after 180 days following the Effective Time shall be delivered to VNR upon demand by VNR and, from and after such delivery, any former holders of ENP Common Units who have not theretofore complied with this Article III shall thereafter look only to VNR for the Merger Consideration payable in respect of such ENP Common Units, any cash in lieu of fractional New Common Units to which they are entitled pursuant to Section 3.4(e), or 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 ENP 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, be held by VNR.  Without limitation of the foregoing, after 180 days following the Effective Time any amounts remaining unclaimed by holders of ENP Common Units shall become the property of VNR, subject to the legitimate claims of any Person previously entitled thereto.
 
(g) No Liability.  To the fullest extent permitted by Law, none of ENP GP, VNR, VNG, ENP, the Surviving Entity or their respective Representatives shall be liable to any holder of ENP Common Units for any VNR 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 VNR, the posting by such Person of an indemnity agreement or a bond, in a customary amount, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of ENP Common Units represented by such Certificate and any distributions to which the holders thereof are entitled pursuant to Section 3.3(b) or (c).
 
(i) Withholding.  The Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of ENP Common Units such amounts as the Exchange Agent reasonably deems to be required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment; provided, however, that the Exchange Agent shall provide reasonable notice to the applicable holders of ENP 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 the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of ENP Common Units in respect of whom such deduction and withholding was made by the Exchange Agent.
 
 
20

 
(j) Book Entry and Admission of Holders of New Common Units as Additional Members of VNR.  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 ENP Common Units in accordance with this Section 3.4, and the compliance by such holders with the requirements of the VNR LLC Agreement, which requirements may be satisfied by each holder of ENP Common Units by the execution and delivery by such holder of a completed and executed Letter of Transmittal, VNR shall be deemed to have automatically consented to the admission of such holder as a member of VNR in respect of its New Common Units and shall reflect such admission on the books and records of VNR.
 
(k) Investment of the Exchange Fund.  VNR shall cause the Exchange Agent to invest any cash included in the Exchange Fund as directed by VNR on a daily basis, in VNR’s sole discretion; provided, however, that (i) any investment of such Exchange Fund shall be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and (ii) no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to ENP 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 VNR.
 
 
21

 
Section 3.5 Anti-Dilution Provisions.
 
  In the event of any subdivisions, reclassifications, recapitalizations, splits, unit distributions, combinations or exchanges of units with respect to, or Rights in respect of, ENP Common Units or VNR Common Units (in each case, as permitted pursuant to Section 4.1(c) and Section 4.2(c), respectively), the Exchange Ratio, the Merger Consideration, the number of New Common Units to be issued in the Merger and the Average Closing Price of VNR Common Units will be correspondingly adjusted to provide to the holders of ENP Common Units the same economic effect as contemplated by this Agreement prior to such event.
 
Section 3.6 Treatment of ENP LTIP.
 
(a) On and after the Effective Time, 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 VNR Common Units or the ENP Common Units or the imposition of any other condition (other than compliance with applicable Securities Act requirements), (i) the ENP LTIP shall be continued by VNR and all ENP obligations assumed by VNR (including obligations with respect to ENP Restricted Units in accordance with Section 3.1(e) hereof) 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 ENP Common Units in the ENP LTIP shall be substituted with references to VNR Common Units, (iii) the number of VNR Common Units that will be available for delivery under the ENP LTIP from and after the Effective Time shall equal the number of ENP Common Units that were available for delivery under the ENP LTIP immediately prior to the Effective Time (reduced by the number of ENP Common Units subject to outstanding ENP Restricted Units if such reduction has not already been taken into account), and (iv) no participant in the ENP LTIP shall have any right to acquire ENP Common Units under the ENP LTIP from and after the Effective Time.

(m) Oil and Gas Matters.
 
(i) For purposes of this Agreement, “ENP Oil and Gas Agreements” means the following types of agreements or contracts to which ENP or any of its Subsidiaries is a party, whether as an original party, by succession or assignment or otherwise, with respect to the Oil and Gas Properties forming the basis for the reserves reflected in the ENP Reserve Report:  oil and gas leases, farm-in and farm-out agreements, agreements providing for an overriding royalty interest, agreements providing for a royalty interest, agreements providing for a net profits interest, crude oil or natural gas sales or purchase contracts, joint operating agreements, unit operating agreements, unit agreements, field equipment leases, and agreements restricting ENP’s ability to operate, obtain, explore for or develop interests in a particular geographic area.  No ENP Oil and Gas Agreements contain any material restriction on ENP’s ability to operate, obtain, explore for or develop interests in a particular geographic area.  Complete copies of all such Oil and Gas Agreements have been made available to VNR.

Section 6.5 Access; Information.
 
(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each party shall, and shall cause its Subsidiaries to, afford the Other Parties and their Representatives, access, during normal business hours throughout the period prior to the Effective Time, to all of its properties, books, contracts, commitments and records, and to its Representatives, and, during such period, it shall, and shall cause its Subsidiaries to, furnish promptly to such Person and its Representatives (i) a copy of each material report, schedule and other document filed by it pursuant to the requirements of federal or state securities law (other than reports or documents that VNR or ENP or their respective Subsidiaries, as the case may be, are not permitted to disclose under applicable Law) and (ii) all other information concerning its business, properties and personnel as the Other Parties may reasonably request.  Notwithstanding the foregoing, neither ENP nor VNR nor any of their respective Subsidiaries shall be required to (A) provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of the institution in possession or control of such information or contravene any Law, fiduciary duty or binding agreement entered into prior to the date of this Agreement or (B) allow any invasive sampling or testing of their properties.  The parties hereto will make appropriate substitute disclosure arrangements under the circumstances in which the restrictions of the immediately preceding sentence apply

Section 6.6 Acquisition Proposals; Change in Recommendation.
 
(a) ENP GP and ENP shall, and they shall cause their Subsidiaries and Representatives to (i) immediately cease and terminate any solicitation, encouragement, discussions or negotiations with any Person that may be ongoing with respect to or that may reasonably be expected to lead to an Acquisition Proposal, and (ii) request such Person to promptly return or destroy all confidential information concerning ENP and its Subsidiaries.

ENP GP and ENP shall as promptly as practicable (in all events within 48 hours) provide to VNR a copy of such Confidentiality Agreement. ENP GP and ENP shall, as promptly as practicable (and in any event within 48 hours), advise VNR in writing of any request for non-public information or any Acquisition Proposal received from any third Person, or any inquiry or request for discussions or negotiations with respect to any Acquisition Proposal, and the material terms of such request, Acquisition Proposal or inquiry.  ENP GP and ENP shall, as promptly as practicable (and in all events within 48 hours), provide to VNR copies of any written materials received by ENP GP, ENP or any of their Subsidiaries or Representations in connection with any of the foregoing, and the identity of the Person or group making any such request, Acquisition Proposal or inquiry.

62

 
(b) By either VNR or ENP, upon written notice to the other party, if:
 
(i) the Merger has not been consummated on or before December 31, 2011 (the “Termination Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(i) shall not be available to a party whose failure to fulfill any material obligation under this Agreement or other material breach of this Agreement has been the primary cause of, or resulted in, the failure of the Merger to have been consummated on or before such Termination Date;
 
(ii) 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 material breach of Section 6.1;

(ii) During the calendar year following the date that the Preliminary Amount was paid to VNR but prior to the passage of 30 Business Days following the filing of the IRS Form 1065 for the prior year, VNR shall submit to ENP a certificate (the “Final Non-Qualifying Income Cushion Certificate”) identifying the actual maximum remaining amount which may still be taken into the gross income of VNR without exceeding the permissible non-qualifying income limits for a publicly traded partnership (for purposes of Section 7704 of the Code), after taking into consideration all other sources of non-qualifying income from the prior year other than the Preliminary Amount (the “Final Non-Qualifying Income Cushion”).  If the Preliminary Amount was (A) less than 90% of the Final Non-Qualifying Income Cushion, then ENP shall pay to VNR an amount which, when combined with Preliminary Amount, will equal 90% of the Final Non-Qualifying Income Cushion, and (B) greater than 90% of the Final Non-Qualifying Income Cushion, then VNR shall return to ENP an amount equal to the excess of Preliminary Amount over 90% of the Final Non-Qualifying Income Cushion.  Any payment under this clause (ii) shall be made by VNR or ENP, as applicable, by wire transfer of immediately available funds to an account designated by VNR or ENP, as applicable within five Business Days following the delivery of the Final Non-Qualifying Income Cushion Certificate.
 
 
64

This SECOND AMENDED AND RESTATED LIMITED LIABILITY COMPANY AGREEMENT (this “Agreement”) of ENCORE ENERGY PARTNERS GP LLC (the “Company”), dated as of [__________], 2011, is adopted, executed and agreed to by the Sole Member (as defined below).
 
WHEREAS, the Company, Encore Energy Partners LP, a Delaware limited partnership (the “Partnership”), Vanguard Natural Resources, LLC, a Delaware limited liability company, Vanguard Natural Gas, LLC, a Delaware limited liability company (the “Sole Member”) and Vanguard Acquisition Company, LLC, a Delaware limited liability company (“Merger Sub”), entered into an Agreement and Plan of Merger, dated July [___], 2011, pursuant to which, among other things, Merger Sub merged with and into the Partnership, with the Partnership continuing as the surviving entity (the “Merger”).
 
WHEREAS, in connection with the Merger, the Sole Member desires to enter into this Agreement;
 
NOW, THEREFORE, the Sole Member does hereby amend and restate the Amended and Restated Limited Liability Company Agreement of the Company, dated as of December 31, 2010 (the “Previous LLC Agreement”), as heretofore amended, to provide, in its entirety, as follows:
 
1 Formation
 
.  Encore Energy Partners GP, LLC has previously been formed as a Delaware limited liability company under and pursuant to the Delaware Limited Liability Company Act (the “Act”).
 
2 Term.
 
  The Company shall have perpetual existence.
 
3 Purposes.
 
  The purposes of the Company are to carry on any lawful business, purpose or activity for which limited liability companies may be formed under the Act.
 
4 Members.
 
  The Sole Member shall be the sole member of the Company.
 
5 Contributions.
 
  The capital contributions as reflected on the Company’s books and records shall constitute the full obligation of the Sole Member to furnish cash or property to the Company, and no additional cash or property shall be required of the Sole Member.  Without creating any rights in favor of any third party, the Sole Member may, from time to time, make additional contributions of cash or property to the capital of the Company, but shall have no obligation to do so.
 
 
 

 
6 Distributions.
 
  The Sole Member shall be entitled (a) to receive all distributions (including, without limitation, liquidating distributions) made by the Company, and (b) to enjoy all other rights, benefits and interests in the Company.
 
7 Management.
 
  The management of the Company shall be exclusively vested in the Sole Member, and the Company shall not have “managers,” as that term is used in the Act.  The powers of the Company shall be exercised by or under the authority of, and the business and affairs of the Company shall be managed under the direction of, the Sole Member.
 
8 Officers. The Sole Member may designate one or more persons to be officers of the Company.  Officers are not “managers,” as that term is used in the Act.  Any officers who are so designated shall have such titles and authority and perform such duties as the Sole Member may delegate to them.  The salaries or other compensation, if any, of the officers of the Company shall be fixed by the Sole Member.  Any officer may be removed as such, either with or without cause, by the Sole Member.  Designation of an officer shall not of itself create contract rights.  Initially, the officers of the Company as of the date of this Agreement shall continue as the officers of the Company.
 
9 Dissolution.
 
  The Company shall dissolve and its affairs shall be wound up at such time, if any, as the Sole Member may elect.  No other event will cause the Company to dissolve.
 
10 Governing Law.

11 Amendments.

12 Liability.
 
  The Sole Member and the officers shall not have any liability for the obligations, debts or liabilities of the Company except to the extent provided in the Act.
 
13 Indemnification.
 
(a)           To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, each Indemnitee 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 Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of such person’s status as an Indemnitee; provided, however that the 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 of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 13, 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.  The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above.  Any indemnification pursuant to this Section 13 shall be made only out of the Company’s assets, it being agreed that a Member shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification.
 
 
 

 
(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 13(a) in defending any Claim shall, from time to time, be advanced by the Company prior to the final disposition of such Claim 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 13.
 
(c)           The indemnification provided by this Section 13 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 and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.
 
(d)           The Company may purchase and maintain insurance, on behalf of former members of the Board of Directors of the Company (“Former Board Members”), the officers and such other Persons as the Company 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, 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 13, 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 13(a) 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 the Members to personal liability by reason of the indemnification provisions set forth in this Agreement.
 
(g)           An Indemnitee shall not be denied indemnification in whole or in part under this Section 13 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction is otherwise permitted by the terms of this Agreement.

 
 

 
(h)           The provisions of this Section 13 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 13 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 13 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, provided such Person became an Indemnitee hereunder prior to such amendment, modification or repeal.

(j)           No Member shall be liable to the Company or to any Member for any loss suffered by the Company unless such loss is caused by such Member’s gross negligence, willful misconduct, intentional violation of law or material breach of this Agreement.  No Member shall be liable for errors in judgment or for any acts or omissions that do not constitute gross negligence, willful misconduct, intentional violation of law or material breach of this Agreement.  Any Member may consult with counsel and accountants in respect of Company affairs and, provided such Member acts in good faith reliance upon the advice or opinion of such counsel or accountants, such Member shall not be liable for any loss suffered by the Company in reliance thereon.

(k)           No Former Board Member shall be liable to the Company or to any Member for any loss suffered by the Company unless such loss is caused by such Former Board Member's gross negligence, willful misconduct, intentional violation of law or material breach of the Previous LLC Agreement.  No Former Board Member shall be liable for errors in judgment or for any acts or omissions that do not constitute gross negligence, willful misconduct, intentional violation of law or material breach of the Previous LLC Agreement.  Any Former Board Member may consult with counsel and accountants in respect of Company affairs and, provided such Former Board Member acts in good faith reliance upon the advice or opinion of such counsel or accountants, such Former Board Member shall not be liable for any loss suffered by the Company in reliance thereon.

(l)           THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 13 ARE INTENDED BY THE MEMBERS 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, SUBJECT TO LIMITS UNDER APPLICABLE LAW.

2. 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 a determination that the Indemnitee is not entitled to be indemnified 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.
 
3. The indemnification provided by this Section 9.1 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Common Units, 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 and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.
 
4. The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.
 
5. 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, it 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 it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership.

8. The provisions of this Section 9.1 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.
 
9. No amendment, modification or repeal of this Section 9.1 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 9.1 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.
 
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 Persons who have acquired interests in the securities of the Partnership, 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 by 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.
 
(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to the Partners, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement.
 
(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 of the Indemnitees 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.
