(e) The Company may issue additional Membership Interests and options, rights, warrants and appreciation rights relating to the Membership Interests for any Company purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the Board shall determine in accordance with Section 9.04.

(f) Each additional Membership Interest authorized to be issued by the Company pursuant to Section 3.01(d) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Membership Interests), as shall be fixed by the Board in accordance with Section 9.04, including (i) the right to share in Company profits and losses or items thereof; (ii) the right to share in Company distributions; (iii) the rights upon dissolution and liquidation of the Company; (iv) whether, and the terms and conditions upon which, the Company may, or shall be required to, redeem the Membership Interest (including sinking fund provisions); (v) whether such Membership Interest is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Membership Interest will be issued, evidenced by certificates and assigned or transferred; and (vii) the right, if any, of each such Membership Interest to vote on Company matters, including matters relating to the relative rights, preferences and privileges of such Membership Interest.

(g) The Board shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Membership Interests and options, rights, warrants and appreciation rights relating to Membership Interests pursuant to this Section 3.01, (ii) reflecting the admission of such additional Members in the books and records of the Company as the record holder of such Membership Interest and (iii) all additional issuances of Membership Interests, in each case including amending this Agreement and Exhibit A and Exhibit B hereof as necessary to reflect any such issuance. The Board, acting pursuant to Section 9.04, shall determine the relative rights, powers and duties of the holders of the Units or other Membership Interests being so issued. The Board shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Membership Interests pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any governmental agency.

Section 3.02 No Liability of Members.

The Members shall have no liability under this Agreement except as expressly provided in this Agreement or the Delaware Act.

Section 3.03 Withdrawal of Members.

No Member shall have any right to withdraw from the Company; provided, however, that when a Transferee becomes registered on the books and records of the Company as the Member with respect to the Membership Interest so transferred, the transferring Member shall cease to be a Member with respect to the Membership Interest so Transferred.

Section 3.04 Record Holders.

The Company shall be entitled to recognize the Person in whose name any Membership Interest is registered on the books and records of the Company as the Member with respect to any Membership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to, or interest in, such Membership Interest on the part of any other Person, regardless of whether the Company shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation or guideline of any governmental agency.

Section 4.01 Transfers Generally.

(a) No Membership Interest shall be Transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV and Article V.

(b) From the execution hereof until the date that is the third anniversary of the Closing Date (the “Control Period”), no Membership Interest shall be Transferred, in whole or in part, except for a Permitted Transfer in accordance with the applicable provisions of this Article IV.

(c) Following the Control Period, no Membership Interest shall be Transferred, in whole or in part, except for (i) a Permitted Transfer in accordance with the applicable provisions of this Article IV or (ii) subject to Section 3.4(c) of the Partnership Agreement, Transfers in accordance with the applicable provisions of Article V and this Article IV.

(d) Notwithstanding any other provision of this Agreement, during and following the Restricted Period, no Member may Transfer less than all of the Membership Interests held by such Member.

(e) No Transfer (including a Permitted Transfer) may be undertaken unless and until the following have occurred: (i) the proposed Transferee shall have agreed in writing to be bound by the terms of this Agreement and provided to the Board its name, address, taxpayer identification number and any other information reasonably necessary to permit the Company to file all required federal and state tax returns or reasonably requested by the Board and (ii) the Member proposing to make such Transfer shall have delivered to the Company an Opinion of Counsel (reasonably acceptable as to form, substance and identity of counsel to the Company) that no registration under the Securities Act is required in connection with such Transfer (unless the requirement of an opinion is waived by the Board).

Section 4.02 Specific Performance.

The Members acknowledge and agree that an award of money damages would be inadequate for any breach of the provisions of this Article IV and Article V and any such breach would cause the non-breaching parties irreparable harm. Accordingly, the Members agree that, in the event of any breach or threatened breach of this Article IV and Article V by a Member, the Members, to the fullest extent permitted by law, will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance; provided such Member is not in material default hereunder. Such remedies will not be the exclusive remedies for any breach of this Article IV and Article V but will be in addition to all other remedies available at law or equity to each of the Members.

RIGHTS UPON A PROPOSED TRANSFER

Section 5.01 Right of First Offer.

(a) Following the Control Period, except for a Permitted Transfer, no Membership Interest shall be Transferred unless the provisions of this Section 5.01 or Section 5.02 are first complied with. If a Member (the “ROFO Seller”) wishes to solicit proposals from third parties to acquire all, but not less than all, of the ROFO Seller’s Units, the ROFO Seller shall first provide a notice (the “ROFO Notice”) to the other Member, with a copy to the Company,

containing: (i) the number and class of Units proposed to be transferred (the “ROFO Units”) and (ii) a request for the other Member (the “ROFO Non-Selling Member”) to specify the purchase price (the “ROFO Price”) and other terms and conditions on which the ROFO Non-Selling Member is willing to purchase the ROFO Units.

(b) Within 30 days after receiving the ROFO Notice, the ROFO Non-Selling Member (the “ROFO Accepting Member”) may elect (the “ROFO Offer Notice”) to purchase all, but not less than all, of the ROFO Units. The ROFO Offer Notice shall specify the ROFO Price and other terms and conditions on which the ROFO Accepting Member is willing to purchase the ROFO Units. If the ROFO Accepting Member submits a ROFO Offer Notice within the time period specified herein, the ROFO Seller shall have 30 days from the date it received the ROFO Offer Notice to elect (the “ROFO Acceptance Notice”) to accept the ROFO Accepting Member’s offer to purchase the ROFO Units.

(c) If the ROFO Seller accepts the ROFO Accepting Member’s offer, the ROFO Accepting Member must purchase the ROFO Units in the manner, and subject to the terms and conditions, described in Section 5.01(d). If the ROFO Seller does not accept the offer from the ROFO Accepting Member or fails to make such election within 30 days after receiving the ROFO Offer Notice, the ROFO Seller may, during the next 120 days, Transfer the ROFO Units to a third party Transferee (i) at a purchase price not less than 105% of the ROFO Price and upon terms no more favorable to the proposed transferee than those specified in the ROFO Notice and (ii) subject to the applicable terms and restrictions of this Agreement, including Article IV.

(d) Sales of the ROFO Units to the ROFO Accepting Member pursuant to this Section 5.01 shall be made at the offices of the Company within 60 days of the delivery of ROFO Acceptance Notice, or on such other date as the parties may agree. Such sales shall be effected by the ROFO Seller’s delivery of the ROFO Units, free and clear of all Encumbrances (other than restrictions imposed by the governing documents of the Company and securities laws), to the ROFO Accepting Member, against payment to the ROFO Seller of the ROFO Price by the ROFO Accepting Member and on the terms and conditions specified in the applicable ROFO Offer Notice.

Section 5.02 Right of First Refusal.

Delivery of the ROFR Sellers’s Notice to the other Member (the “ROFR Non-Transferring Member”) shall constitute an offer (a “ROFR Offer”) by the ROFR Seller to sell the ROFR Units at the ROFR Sale Price to the ROFR Non-Transferring Member, which shall remain outstanding for a period of thirty (30) days after the delivery of the ROFR Seller’s Notice (subject to extension as provided below, the “ROFR Period”).

(b) During the ROFR Period, the ROFR Non-Transferring Member shall have the right to accept the ROFR Offer by delivering a notice to the ROFR Seller (a “ROFR Acceptance Notice”), with a copy to the Company, of its acceptance of the ROFR Offer at the ROFR Sale Price and on the same terms specified in the ROFR Seller’s Notice.

(c) A failure by the ROFR Non-Transferring Member to validly deliver a ROFR Acceptance Notice during the ROFR Period shall be deemed a rejection of the ROFR Offer and a waiver of the ROFR Non-Transferring Member’s right to purchase any portion of the ROFR Units.

(d) If the ROFR Non-Transferring Member does not elect to purchase all of the ROFR Units pursuant to this Section 5.02, then the ROFR Seller shall be free, for a period of sixty (60) days from the date of the expiration of the ROFR Period, to sell such ROFR Units to a third party (the “Proposed Transferee”) (x) at a price per Unit equal to or greater than the ROFR Price and upon terms no more favorable to the Proposed Transferee than those specified in the ROFR Seller’s Notice and (y) subject to the applicable terms and restrictions of this Agreement, including Article IV.

(a) If there is a net decrease in Company Minimum Gain during any Allocation Year, each Economic Member shall be allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. This Section 8.03(a) is intended to comply with the Company Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(b) Except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Allocation Year, any Economic Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such Allocation Year shall be allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. This Section 8.03(b) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c) In the event any Economic Member has a deficit balance in its Capital Account at the end of any Allocation Year in excess of the sum of (A) the amount such Economic Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Economic Member is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Economic Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 8.03(c) shall be made only if and to the extent that such Economic Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VIII have been tentatively made as if this Section 8.03(c) were not in this Agreement.

(d) In the event any Economic Member has a deficit balance in its Capital Account at the end of any Allocation Year in excess of the sum of (A) the amount such Economic Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Economic Member is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Economic Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 8.03(d) shall be made only if and to the extent that such Economic Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article VIII have been tentatively made as if Section 8.03(c) and this Section 8.03(d) were not in this Agreement.

(e) Nonrecourse Deductions for any Allocation Year shall be allocated to the Economic Members pro rata in accordance with each Economic Member’s Ownership Percentage.

(f) Member Nonrecourse Deductions for any Allocation Year shall be allocated 100% to the Economic Member that bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Economic Member bears the economic risk of loss with respect to a Member Nonrecourse Debt, such Economic Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Economic Members in accordance with the ratios in which they share such economic risk of loss.

(g) For purposes of Treasury Regulation Section 1.752-3(a)(3), the Economic Members agree that Nonrecourse Liabilities of the Company shall be allocated to the Economic Members pro rata in accordance with each Economic Member’s Ownership Percentage.

(h) To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Economic Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(i) Notwithstanding any other provision of this Section 8.03, the allocations set forth in Sections 8.03(a), (b), (c), (d), (e), (f) and (h) (the “Required Allocations”) shall be taken into account so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Economic Member pursuant to Sections 8.02 and 8.03, together, shall be equal to the net amount of such items that would have been allocated to each such Economic Member under Section 8.02 and Section 8.03 had the Required Allocations and this Section 8.03(i) not otherwise been provided in this Agreement. The Company may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made.

(j) Items of income, gain, loss and deduction realized in any taxable year that includes a Dissolution Event shall be allocated in a manner that will cause, to the extent possible, the ratio of each Economic Member’s Capital Account to the sum of all Economic Members’ Capital Accounts to be equal to such Economic Member’s Ownership Percentage. Upon a Dissolution Event, if any property is distributed in kind, any unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously shall be allocated among the Economic Members as if there were a taxable disposition of that property for the fair market value of that property on the date of distribution.

(k) The allocations in Section 8.02, this Section 8.03 and Section 8.05, and the provisions of this Agreement relating to the maintenance of Capital Accounts, are included to ensure compliance with requirements of the federal income tax law (and any applicable state income tax laws). Such provisions are intended to comply with Treasury Regulations Sections 1.704-1 and 1.704-2 and shall be interpreted and applied in a manner consistent with such Treasury Regulations and any amendment or successor provision thereto. The Management Members shall cause appropriate modifications to be made if unanticipated events might otherwise cause this Agreement not to comply with such Treasury Regulations, so long as such modifications do not cause a material change in the relative economic benefit of the Economic Members under this Agreement.

Section 8.04 Section 704(c).

In accordance with Section 704(c) of the Code and the Treasury Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Economic Members to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of same under this Agreement). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (b) of the definition of Gross Asset Value hereof, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the Treasury Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement; provided that the Company shall use the traditional method without curatives set forth in Treasury Regulation Section 1.704-3(b). Allocations pursuant to this Section 8.04 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Economic Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

Section 8.05 Varying Interests.

All items of income, gain, loss, deduction or credit shall be allocated, and all distributions shall be made, to the Persons shown on the records of the Company to have been Economic Members as of the last calendar day of the period for which the allocation or distribution is to be made. Notwithstanding the foregoing, if during any taxable year there is a change in any Economic Member’s Ownership Percentage, the Economic Members agree that their allocable shares of such items for the taxable year shall be determined on any method determined by the Board to be permissible under Code Section 706 and the related Treasury Regulations to take account of the Economic Members’ varying Ownership Percentages.

Section 8.06 Withheld Taxes.

All amounts withheld pursuant to the Code or any provision of any state or local tax law with respect to any payment, distribution or allocation to the Company or the Economic Members shall be treated as amounts distributed to the Economic Members pursuant to this Article VIII for all purposes of this Agreement. The Company is authorized to withhold from distributions, or with respect to allocations, to the Economic Members and to pay over to any federal, state or local government any amounts required to be so withheld pursuant to the Code or any provision of any other federal, state or local law and shall allocate such amounts to those Economic Members with respect to which such amounts were withheld.

Section 8.07 Limitations on Distributions.

Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Member on account of its interest in the Company if such distribution would violate Section 18-607 of the Delaware Act or other applicable law. All distributions required to be made under this Agreement shall be made subject to Sections 18-607 and 18-804 of the Delaware Act.

(iii) Alternate Directors. Alternate Directors shall be entitled to receive notice of and attend meetings of the Board; provided that such attendance shall be only in an observer capacity unless a particular Alternate Director is serving in place of a Management Member’s designated Director. An Alternate Director may, without prior

If any other Director shall cease to serve as a Director for any reason, the vacancy resulting thereby will be filled by another Director designated in accordance with Section 9.02(b)(ii).

(d) Changes in Size.

Special meetings of the Board, to be held at the offices of the Company (or such other place as shall be determined by the Board), shall be called at the direction of any one Director. Attendance of a Director at a meeting shall constitute a waiver of notice of such meeting, except where a Director attends a meeting for the express purpose of objecting to the transaction of any business on the ground that such meeting is not properly called or convened. The reasonable costs and expenses incurred by the Directors and Alternate Directors in connection with any meeting of the Board shall be borne and paid by the Company (and any Director and Alternate Director may obtain reimbursement from the Company for any such reasonably documented costs and expenses).

(b) Actions Requiring Approval of the Board. In addition to such other matters as the Board may from time to time by resolution in accordance with Section 9.04(a) determine, and except for such actions as the Board may from time to time in accordance with Section 9.04(a) delegate to the officers of the Company that may be taken without approval of the Board, the Company shall not, and shall cause the Group Members not to, and shall not authorize or permit any officer or agent of the Company on behalf of the Company or of any Group Member to, effect any non-ministerial action, including the following actions:

Within five days after receipt of the Deadlock Notice, the receiving Management Member shall submit to the other Management Member a written response (a “Dispute Response”). The Dispute Notice and the Dispute Response shall each include (A) a statement setting forth the position of the Management Member giving the notice and a summary of arguments supporting such position and (B) the name and title of a senior representative of such Management Member who has authority to settle the Deadlock.

(iii) If such Deadlock is not resolved within 60 days of delivery of the Deadlock Response, (A) prior to the IPO Date, either Management Member may require such Deadlock to be submitted to nonbinding mediation in Houston, Texas, before an impartial mediator acceptable to both Management Members and with senior representatives of both Members who have authority to settle the Deadlock in attendance, or (B) on or after the IPO Date, such Deadlock shall be resolved by the affirmative vote of a majority of the Independent Directors on the Board.

(iv) Notwithstanding anything herein to the contrary, until a Deadlock is resolved, each Management Member agrees to continue to perform its obligations under this Agreement and to cause its Representatives to continue to perform their obligations under this Agreement. In the event a Deadlock exists with respect to any Annual Budget, then, until such time as such Deadlock is resolved, the Annual Budget for such calendar year shall be based on the corresponding portions of the Annual Budget for the preceding calendar year (excluding any unusual or extraordinary revenues, expenses or capital expenditures that occurred during such prior calendar year), together with any additional amounts to the extent necessary, when combined with amounts authorized to be spent in such last Annual Budget, to meet the Partnership’s existing commitments and obligations and to conduct and maintain the Partnership’s operations and properties in the ordinary course of business. With respect to non-recurring amounts and capital expenditures, if any, for which there is no corresponding portion of the Annual Budget for the preceding calendar year, only budgeted amounts directed or approved by the Board of Directors on a case by case basis shall be utilized.

Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board need be specified in the notice of such meeting. A meeting may be held at any time without notice if all the Directors are present or if those not present waive notice of the meeting either before or after such meeting. Notwithstanding anything in the foregoing to the contrary, the failure to give notice or documents or other information to an Alternate Director that is acting solely in an observer capacity shall not affect the validity of any action taken by the Board.

Section 9.06 Action by Written Consent of Board.

To the extent permitted by applicable law, the Board may act without a meeting, without notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by all Directors (which, for the avoidance of doubt, need not include the consent of any Alternate Directors unless a particular Alternate Director is serving in place of a Management Member’s designated Director). All actions taken by the Board in the form of a written consent shall be distributed to each Director and Alternate Director promptly upon the taking of such action.

Section 9.07 Conference Telephone Meetings.

(c) The indemnification provided by this Section 13.01 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of a Majority Interest or of the Board, as a matter of law, in equity 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 the Company, its Affiliates, the Indemnitees 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 or any of its Affiliate’s activities or such Person’s activities on behalf of the Company or any of its Affiliates, 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 13.01, the Company 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 Company 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 13.01(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 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 13.01 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 13.01 are for the benefit of the Indemnitees and their heirs, successors, assigns, executors and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i) Any amendment, modification or repeal of this Section 13.01 or any provision hereof shall be prospective only and shall not in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Company, nor the obligations of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 13.01 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.

(j) TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AND SUBJECT TO SECTION 13.01(a), THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 13.01 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.

Section 13.02 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 Persons who have acquired interests in the Membership Interests, 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) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Company or to the Members, the Indemnitee acting in connection with the Company’s business or affairs shall not be liable to the Company or to any Member for its good faith reliance on the provisions of this Agreement, and the provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of any Indemnitee otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of the Indemnitee.

(c) Any amendment, modification or repeal of this Section 13.02 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 13.02 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.

(b) The Directors may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by the Directors, and any act taken or omitted to be taken in reliance upon the advice or opinion (including an Opinion of Counsel) of such Persons as to matters that the Directors reasonably believe to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such advice or opinion.

(a) Whenever a Member makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its capacity as a Member, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then such Member or its Affiliates causing it to do so shall be entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty (including any fiduciary duty) or obligation whatsoever to the Company, any Member or Director, and the Member, or such Affiliates causing it to do so, shall not, to the fullest extent permitted by law, be required to act pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, it being the intent of all Members that such Member or any such Affiliate, in its capacity as a Member, shall have the right to make such determination solely on the basis of its own interests.

Notwithstanding any duty otherwise existing at law or in equity, any matter approved by the Board in accordance with the provisions, and subject to the limitations, of the Partnership Agreement, shall not be deemed to be a breach of any duties owed by the Board or any Director to the Company or the Members.

(c) The provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties (including fiduciary duties) and liabilities of an officer of the Company or a Member or Director otherwise existing at law, in equity or by operation of the preceding sentences, are agreed by the Company and the Members to replace such duties and liabilities of such officer, Member or Director. The Members (in their own names and in the name and on behalf of the Company), acknowledge, affirm and agree that (i) none of the Members would be willing to make an investment in the Company or enter into this Agreement, and no Representative would be willing to so serve on the Board, in the absence of this Section 13.05, and (ii) they have reviewed and understand the provisions of Section 18-1101(b) and (c) of the Delaware Act.

(d) Nothing in this Agreement is intended to or shall eliminate any implied contractual covenant of good faith and fair dealing, the requirement not to waste Company assets or otherwise relieve or discharge any Representative or Member from liability to the Company or the Members on account of any fraudulent or intentional misconduct of such Representative or Member.

With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds.
