Any Disposition of Membership Interests may be made only if the Board shall have received an executed written joinder agreement of the transferee, in form and substance reasonably satisfactory to the Board, whereby the transferee, if applicable, agrees to be bound by all of the terms and conditions of this Agreement applicable to Members.

Section 5.2 Additional Capital Contributions by Members.

(a) If, at any time, the Board determines that the Company is in need of additional capital, then, with the prior written consent of each Member, each Member shall be obligated to contribute in cash such capital, subject to the limitations contained in this Section 5.2 or elsewhere in this Agreement, pro rata in accordance with its Sharing Ratio in effect at the time of such contribution.

An advance described in this Section 5.3 constitutes a loan from the Member to the Company, bears interest at such rate from the date of the advance until the date of payment and is not a Capital Contribution.

Section 5.4 Return of Contributions. Except as expressly provided herein, no Member is entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Account or its Capital Contributions.

DISTRIBUTIONS AND ALLOCATIONS

Section 6.1 Distributions. (a) Except as otherwise provided in Section 6.2, distributions to the Members shall be made only to all Members simultaneously in proportion to their respective Sharing Ratios (at the time the amounts of such distributions are determined) and in such aggregate amounts and at such times as shall be determined by the Board; provided, however, that any loans from Members pursuant to Section 5.3 shall be repaid prior to any distributions to Members pursuant to this Section 6.1.

(b)

(i) Subject to the availability of sufficient funds (without taking into account any reserves for capital expenditures or other liabilities that have not been incurred by the Company or any of its Subsidiaries, other than reserves reasonably anticipated to satisfy operating expenses for the 45 days following such date of determination for which sources of funding (including available debt facilities) are not then available), the Company shall distribute to each Member with respect to each taxable quarter of the Company an amount of cash sufficient to permit such Member to satisfy its tax liabilities arising from allocations of income, gain, loss, deduction and credit and guaranteed payments (if any) deemed received by such Member pursuant to Code Section 707(c) (other than guaranteed payments in respect of services performed by such Member) (a “Tax Distribution”), in each case, to the extent attributable to such Member’s Membership Interest in the Company in any taxable quarter for which such an allocation is made, determined using the same principles as described in Section 6.1(b)(ii) (as applicable), but for the taxable quarter in question and adjusted for prior taxable quarters of the tax year and losses and deductions of the Company realized in prior tax years to the extent such losses and deductions have not been offset by income or gain of the Company realized in subsequent taxable periods. In the event the

Company does not have sufficient funds (without taking into account any reserves for capital expenditures or other liabilities that have not been incurred by the Company or any of its Subsidiaries, other than reserves reasonably anticipated to satisfy operating expenses for the 45 days following such date of determination for which sources of funding (including available debt facilities) are not then available) to make Tax Distributions as and when required by the terms of this Agreement, the Company shall use its commercially reasonable efforts to obtain funds necessary to make such Tax Distributions as promptly as possible.

(ii) The Tax Distribution payable to the Members shall be pro rata based on the Members’ Sharing Ratios; provided, however, that the Tax Distribution to each Member shall be equal at least to its “Tax Amount.” As used herein, “Tax Amount” means the product of (x) the Company’s reasonable estimation of the taxable income, gain, loss, deduction, credit, and guaranteed payments (to the extent described in Section 6.1(b)(i) above) allocated to such Member for such Allocation Period, multiplied by (y) the highest marginal effective rate of U.S. federal, state and local income tax (including for this purpose any tax under Code Section 1411 or similar provisions of law) applicable to an individual or corporation (whichever has the higher rate) resident in New York, New York, taking account of any difference in rates applicable to ordinary income, capital gains and “qualified dividends,” as such term is defined in Code Section 1(h) and any allowable deductions in respect of such state and local taxes in computing such Member’s liability for U.S. federal income taxes, and such other assumptions as the Company shall reasonably determine.

For the avoidance of doubt, in determining the Tax Amount for any Member, there shall be taken into account any items allocated to such Member pursuant to Code Section 704(c) (including any amounts allocable pursuant to the “remedial allocation method” described in Treasury Regulation Section 1.704-3(d), if applicable), and any items taken into account by such Partner (or its direct or indirect owner) pursuant to the provisions of Code Section 613A(c)(7)(D) and the Treasury Regulations promulgated thereunder).

(iii) Notwithstanding anything in this Section 6.1(b) to the contrary, for any taxable quarter, if the Company does not have sufficient funds (without taking into account any reserves for capital expenditures or other liabilities that have not been incurred by the Company or any of its Subsidiaries, other than reserves reasonably anticipated to satisfy operating expenses for the 45 days following such date of determination for which sources of funding (including available debt facilities) are not then available) available to provide all Members with the full amount of their Tax Distributions, then Tax Distributions shall be made to the Members pro rata in proportion to the amount of their respective Tax Distributions.

(iv) A final accounting for Tax Distributions shall be made for each Allocation Period after the Company’s actual taxable income has been determined, and any shortfall in the amount of Tax Distributions a Member received for such taxable year based on such final determination shall promptly be distributed to such Member, and any excess in the amount of Tax Distributions a Member received for such taxable year shall be applied against the subsequent Tax Distributions due to such Member;

provided, however, for any Allocation Period, if the Company does not have funds sufficient to distribute to each Member the amount of such Member’s shortfall, then such available funds shall be distributed in a manner and priority analogous to the manner and priority described in Section 6.1(b)(iii) (regarding insufficient funds with respect to a given taxable quarter). For any Allocation Period, if any shortfall remains for any Member after giving effect to the preceding sentence, the amount of such shortfall shall be added to the Tax Distributions payable to such Member in succeeding Allocation Periods until the time such shortfall is paid. In addition, in the event of any audit adjustment by a taxing authority which affects the amount of taxable income allocated or required to be allocated to the Members in any year, or in the event the Company files an amended return which has such effect, the aggregate amount of Tax Distributions that should have been made with respect to such year shall be recalculated by giving effect to such audit adjustment or changes reflected in the amended return, as applicable (treating any interest or penalties incurred by any of the Members in connection therewith as an addition to the assumed tax liability of such Members), and any excess or shortfall in the resulting amount of Tax Distributions shall be treated in accordance with the preceding two (2) sentences.

(v) Tax Distributions shall be considered advanced distributions made pursuant to the applicable provisions of Section 6.1 and shall reduce such future distributions (including distributions under Section 12.2).

(vi) The parties agree that it is not expected that the Company will have any Profit or Loss and, as such, a Tax Distribution under this Section 6.1(b) is unlikely to be needed.

Section 6.2 Distributions on Dissolution and Winding Up. Upon the dissolution and winding up of the Company, after adjusting the Capital Accounts, if any, for all distributions made under Section 6.1 and all allocations under Article VI, all available proceeds distributable to the Members as determined under Section 12.2 shall be distributed (i) in the manner set forth in Section 6.1(a), or (ii) if the obligation to maintain Capital Accounts has been suspended under Section 13.11, to the sole Member.

Section 6.3 Allocations.

(a) Profits and Losses.

(i) General Application. For each Allocation Period, after giving effect to Section 6.3(b), the rules set forth below in this Section 6.3(a) shall apply for the purpose of determining each Member’s allocable share of the items of income, gain, loss and expense of the Company comprising Profits or Losses of the Company for such Allocation Period.

(ii) Hypothetical Liquidation. The items of income, expense, gain and loss of the Company comprising Profits or Losses for an Allocation Period shall be allocated among the Persons who were Members during such Allocation Period in a manner that shall, as nearly as possible, cause the Capital Account balance of each Member at the end of such fiscal year to equal the excess (which may be negative) of:

(A) the amount of the hypothetical distribution (if any) that such Member would receive if, on the last day of the fiscal year, (x) all Company assets were sold for cash equal to their respective Gross Asset Values, taking into account any adjustments thereto for such fiscal year, (y) all Company liabilities were satisfied in cash according to their terms (limited, with respect to each Nonrecourse Liability or any Member Nonrecourse Debt with respect to such Member, to the Gross Asset Values of the assets securing such liability), and (z) the net proceeds thereof (after satisfaction of such liabilities) were distributed in full pursuant to Section 12.2(a)(iii) hereof; over

(B) the sum of (x) the amount, if any, without duplication, that such Member would be obligated to contribute to the capital of the Company, (y) such Member’s share of Company Minimum Gain determined pursuant to Treasury Regulations Section 1.704-2(g), and (z) such Member’s share of Member Minimum Gain determined pursuant to Treasury Regulations Section 1.704 2(i)(5), all computed as of the hypothetical sale described in Section 6.3(a)(ii)(A) hereof;

(b) Regulatory Allocations. Notwithstanding the foregoing provisions of Section 6.3(a), the following special allocations will be made in the following order of priority:

(i) Minimum Gain Chargeback. If there is a net decrease in Company Minimum Gain during an Allocation Period, then each Member will be allocated items of Company income and gain for such Allocation Period (and, if necessary, for subsequent Allocation Periods) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, determined in accordance with Treasury Regulations Section 1.704-2(g)(2). This Section 6.3(b)(i) is intended to comply with the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(f) and will be interpreted consistently therewith.

(ii) Member Minimum Gain Chargeback. If there is a net decrease in Member Minimum Gain attributable to a Member Nonrecourse Debt during any Company Allocation Period, each Member who has a share of the Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(5), will be specially allocated items of Company income and gain for such Allocation Period (and, if necessary, subsequent Allocation Periods) in an amount equal to such Member’s share of the net decrease in Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of Treasury Regulations Section 1.704-2(i)(4). This Section 6.3(b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(i)(4) and will be interpreted consistently therewith.

(iii) Qualified Income Offset. If any Member unexpectedly receives an adjustment, allocation, or distribution of the type contemplated by Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of income, gain and Simulated Gain will be allocated to all such Members (in proportion to the amounts of their respective deficit Adjusted Capital Accounts) in an amount and manner sufficient to eliminate the deficit balance in the Adjusted Capital Account of such Member as quickly as possible, provided that an allocation pursuant to this Section 6.3(b)(iii) shall be made if and only to the extent that such Member would have an Adjusted Capital Account deficit after all other allocations provided for in this Section 6.3 have been tentatively made as if this Section 6.3(b)(iii) were not in this Agreement. It is intended that this Section 6.3(b)(iii) qualify and be construed as a “qualified income offset” within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

(iv) Gross Income Allocation. In the event any Member has a deficit Capital Account at the end of any Allocation Period which is in excess of the sum of (x) the amount such Member is obligated to restore pursuant to any provision of this Agreement and (y) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentence of Treasury Regulation Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 6.3(b)(iv) shall be made only if and to the extent that such Member would have a deficit Capital Account balance in excess of such sum after all other allocations provided for in this Section 6.3 have been made as if Section 6.3(b)(iii) hereof and this Section 6.3(b)(iv) were not in this Agreement.

(v) Limitation on Allocation of Net Loss. If the allocation of Losses, Simulated Depletion or Simulated Losses to a Member as provided in Section 6.3(a) hereof would create or increase an Adjusted Capital Account deficit, there will be allocated to such Member only that amount of Losses, Simulated Depletion or Simulated Losses as will not create or increase an Adjusted Capital Account deficit. The Losses, Simulated Depletion or Simulated Losses that would, absent the application of the preceding sentence, otherwise be allocated to such Member will be allocated to the other Members in accordance with their relative proportion of Units, subject to the limitations of this Section 6.3(b)(v).

(vi) Certain Additional Adjustments. To the extent that an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) or Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts will 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 gain or loss will be specially allocated to the Members in accordance with their Interests in the Company in the event that Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Members to whom such distribution was made in the event that Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

(vii) Nonrecourse Deductions. Nonrecourse Deductions for each Allocation Period of the Company will be allocated to the Members in proportion to their respective Sharing Ratios.

(viii) Member Nonrecourse Deductions. Member Nonrecourse Deductions will be allocated each Allocation Period to the Member that bears the economic risk of loss (within the meaning of Treasury Regulations Section 1.752-2) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable.

(ix) Simulated Depletion, Simulated Loss. Simulated Depletion for each Depletable Property, and Simulated Loss upon disposition of Depletable Property, shall be allocated among the Members in proportion to their shares of Simulated Basis in such property.

(i) Except as provided in Section 6.3(c)(ii), Section 6.3(c)(iii), and Section 6.3(d) hereof, for income tax purposes under the Code and the Treasury Regulations, each Company item of income, gain, loss, deduction and credit will be allocated between the Members as its correlative item of “book” income, gain, loss, deduction or credit is allocated pursuant to this Article VI.

(ii) Tax items with respect to Company assets that are contributed to the Company with a Gross Asset Value that varies from its basis in the hands of the contributing Member immediately preceding the date of contribution will be allocated between the Members for income tax purposes pursuant to Treasury Regulations promulgated under Code Section 704(c) so as to take into account such variation. The Company will account for such variation under any method approved under Code Section 704(c) and the applicable Treasury Regulations and, the Parties agree that, unless and until a different method is selected pursuant to the provisions of this Agreement, the Company shall use the remedial method pursuant to Treasury Regulations Section 1.704-3(d). If the Gross Asset Value of any Company asset is adjusted pursuant to the definition of “Gross Asset Value” herein, subsequent allocations of income, gain, loss, deduction and credit with respect to such Company asset will take account of any variation between the adjusted basis of such Company asset for federal income tax purposes and its Gross Asset Value in a manner consistent with Code Section 704(c) and the Treasury Regulations promulgated thereunder under any method approved under Code Section 704(c) and the applicable Treasury Regulations as chosen by the Company. Allocations pursuant to this Section 6.3(c)(ii) are solely for purposes of federal, state and local taxes and will not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of net Profits, net Losses and any other items or distributions pursuant to any provision of this Agreement.

(iii)

(A) If the Company recognizes Depreciation Recapture with respect to the sale of any Company asset, (i) the portion of the gain on such sale which is allocated to a Member pursuant to Section 6.3(a) and Section 6.3(b) shall be treated as consisting of a portion of the Company’s Depreciation Recapture on the sale and a portion of the balance of the Company’s remaining gain on such sale under principles consistent with Treasury Regulations Section 1.1245-1 and (ii) if, for U.S. federal income tax purposes, the Company recognizes both “unrecaptured section 1250 gain” (as defined in Code Section 1(h)) and gain treated as ordinary income under Code Section 1250(a) with respect to such sale, the amount treated as Depreciation Recapture under Section 6.3(d)(iii) hereof shall be comprised of a proportionate share of both such types of gain.

(B) For purposes of this Section 6.3(c)(iii), “Depreciation Recapture” means the portion of any gain from the disposition of an asset of the Company which, for U.S. federal income tax purposes, (i) is treated as ordinary income under Code Section 1245, (ii) is treated as ordinary income under Code Section 1250 or (iii) is “unrecaptured section 1250 gain” as such term is defined in Code Section 1(h).

(d) Income Tax Allocations with respect to Depletable Properties.

(i) Pursuant to Code Section 613A(c)(7)(D) and the Treasury Regulations promulgated thereunder, cost and percentage depletion deductions with respect to any Depletable Property shall be computed separately by the Members rather than the Company. For purposes of such computations, the federal income tax basis of each Depletable Property shall be allocated to each Member in accordance with such Member’s Sharing Ratio as of the time such Depletable Property is contributed to or acquired by the Company (and any additions to such federal income tax basis resulting from expenditures required to be capitalized in such basis shall be allocated among the Members in a manner designed to cause the Members’ proportionate shares of such adjusted federal income tax basis to be in accordance with their Sharing Ratios as determined at the time of any such additions), and shall be reallocated among the Member in accordance with the Members’ Sharing Ratios as determined immediately following the occurrence of an event giving rise to an adjustment to the Gross Asset Values of the Company’s Depletable Properties pursuant to clause (ii) of the definition of Gross Asset Value.

(ii) For purposes of the separate computation of gain or loss by each Member on the taxable disposition of Depletable Property, the amount realized from such disposition shall be allocated (i) first, to the Members in an amount equal to the Simulated Basis in such Depletable Property in proportion to their allocable shares thereof and (ii) second, any remaining amount realized shall be allocated consistent with the allocation of Simulated Gains.

(iii) The allocations described in clauses (i) and (ii) of this Section 6.3(d) are intended to be applied in accordance with the Members’ “interests in partnership capital” under Code Section 613A(c)(7)(D); provided that the Members understand and agree that the Company, in good faith, authorize special allocations of federal income tax basis, income, gain, deduction or loss, as computed for federal income tax purposes, in order to eliminate differences between Simulated Basis and adjusted federal income tax basis with respect to Depletable Properties, in such manner as determined consistent with the principles outlined in Section 6.3(c)(ii). The provisions of this Section 6.3(d) and the other provisions of this Agreement relating to allocations under Code Section 613A(c)(7)(D) are intended to comply with Treasury Regulation Section 1.704-1(b)(4)(v) and shall be interpreted and applied in a manner consistent with such Treasury Regulations.

(iv) Each Member shall separately keep records of its share of the adjusted tax basis in each Depletable Property, adjust such share of the adjusted tax basis for any cost or percentage depletion allowable with respect to such property and use such adjusted tax basis in the computation of its cost depletion or in the computation of its gain or loss on the disposition of such property by the Company. Upon the request of the Company, each Member shall advise the Company of its adjusted tax basis in each Depletable Property and any depletion computed with respect thereto, both as computed in accordance with the provisions of this subsection. The Company may rely on such information and, if it is not provided by the Member, may make such reasonable assumptions as it shall determine with respect thereto. The Company shall provide each Member with information reasonably requested by such Member to comply with this Section 6.3(d)(iv) and other tax reporting obligations.

(e) Other Provisions.

(i) For any Allocation Period or other period during which any part of any Interest in the Company is Transferred between the Members or to another Person (other than by pledge of, or grant of a security interest in, such Interest), the portion of the Profits, Losses and other items of income, gain, loss, deduction and credit that are allocable with respect to such part of an Interest in the Company will be apportioned between the Transferor and the Transferee under any method allowed pursuant to Code Section 706 and the applicable Treasury Regulations as determined by the Company, although an interim closing of the books method shall be used if the Transferor agrees to reimburse the Company for reasonable costs incurred.

(ii) In the event that the Code or any Treasury Regulations require allocations of items of income, gain, loss, deduction or credit different from those set forth in this Article V, the Company is hereby authorized to adjust or amend the allocations to the extent necessary to satisfy the Code and any Treasury Regulations, and no such new allocation will give rise to any claim or cause of action by any Member.

(iii) For purposes of determining the Members’ proportional share of the Company’s “excess nonrecourse liabilities” within the meaning of Treasury Regulations Section 1.752-3(a)(3), the Members’ interests in profits will be equal to their respective Sharing Ratios.

(iv) Credits. All tax credits shall be allocated among the Members as determined by the Company, consistent with applicable law.

(f) Valuation; Revaluation. Except as otherwise specifically provided in this Agreement, valuations will be made by the Company or by independent third parties appointed by the Company and deemed qualified by the Company to render an opinion as to the value of the Company’s assets, using such methods and considering such information relating to the investments, assets and liabilities of the Company as the Company or independent third party, as the case may be, may determine in the discretion of the Company.

The Parties agree that the Company will not receive a distributive share of profits or losses (or underlying items of income, gain, deduction or loss) from the Partnership.

Section 6.4 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 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 Member’s Sharing Ratio, the 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 Members’ varying Sharing Ratios.

Section 6.5 Withheld Taxes. All amounts withheld pursuant to the Code or any provision of any state, local or foreign tax law with respect to any payment, distribution or allocation to the Company or the Members shall be treated as amounts distributed to the Members pursuant to this Article VI for all purposes of this Agreement. The Company is authorized to withhold from distributions, or with respect to allocations, to the Members and to pay over to any federal, state, local or foreign government any amounts required to be so withheld pursuant to the Code or any provision of any other federal, state, local or foreign law and shall allocate such amounts to those Members with respect to which such amounts were withheld.

Section 6.6 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 Act or other Applicable Law.

ARTICLE VII

MANAGEMENT

Section 7.1 Management by Board. (a) The management of the Company is fully reserved to the Members, 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 Members, who shall make all decisions and take all actions for the Company.

(b) The Members shall have the power and authority to delegate to one or more other persons the Members’ rights and power to manage and control the business and affairs, or any portion thereof, of the Company, including to delegate to agents, officers and employees of a Member or the Company, and to delegate by a management agreement with or otherwise to other Persons.

(c) The Members hereby expressly delegate to the board of directors of the Company (the “Board”), to the fullest extent permitted under this Agreement and the Act, all of the Members’ power and authority to manage and control the business and affairs of the Company. The Board may at any time designate one or more other Persons to be officers of the Company and/or to assist in carrying out the Board’s decisions and the day-to-day activities of the Company. SXE GP and any officers are not “managers” as that term is used in the Act. Any officers who are designated as such shall have such titles and authority and perform such duties as the Board may delegate to them. The salaries or other compensation, if any, of the officers of the Company shall be fixed by the Board in accordance with Section 7.11(c)(vii). Any officer may be removed as such, either with or without cause, by the Board and any vacancy occurring in any office of the Company may be filled by the Board, in each case in accordance with Section 7.11(c)(vi). Designation of an officer shall not of itself create contract rights.

Section 7.2 Number; Qualification; Tenure. (a) The number of Directors constituting the Board shall initially be eight. A Director need not be a Member.

(b) So long as (i) BBTS is a Designating Party, BBTS shall have the right to designate four Directors (two of whom shall be designated by BBTS as “TW Directors” and two of whom shall be designated by BBTS as “EIG Directors”), (ii) Southcross is a Designating Party, Southcross shall have the right to designate two Directors, (iii) PMM is affiliated with the Company or any Designating Party, PMM shall have the right to designate one Director, and (iv) DWB is affiliated with the Company or any Designating Party, DWB shall have the right to designate one Director; and each such Person shall have the sole right to remove (with or without cause), and to fill vacancies with respect to the Director(s) designated by such Person.

Each Director shall serve as a Director of the Company indefinitely (until his or her earlier death, resignation or removal).

(c) The right of each Designating Party to designate Directors is transferable, and may be transferred by a Designating Party in whole (and not in part), to any transferee of Units of such Designating Party (or its Permitted Transferees) to the extent permitted pursuant to Section 4.2, provided such transferee has a Sharing Ratio of at least 10% after giving effect to such transfer. Upon any assignment by a Designating Party of its right to designate Directors, such Designating Party shall cease to be a Designating Party.

(d) Upon the date a Member ceases to be a Designating Party (i) such Person shall no longer have the right to designate any Director or any member of the SXE GP Board, (ii) other than upon BBTS ceasing to be a Designating Party as a result of a BBTS Distribution,

the size of the Board shall be reduced by the number of such forfeited board seats and (iii) any Director or member of the SXE GP Board designated by such Person shall be deemed to have resigned as a Director or member of the Board and as a member of the SXE GP Board, as applicable.

(e) Any matter involving a conflict between the Company, a Member or any Affiliate of a Member shall be administered on behalf of the Board by the Directors who are disinterested in such matter.

Section 7.3 Regular Meetings. Regular quarterly and annual meetings of the Board shall be held at such time and place as shall be designated from time to time by resolution of the Board. Notice of such regular quarterly and annual meetings shall not be required.

All notices and other communications to be given to Directors shall be sufficiently given for all purposes hereunder if in writing and delivered by hand, courier or overnight delivery service or three Days after being mailed by certified or registered mail, return receipt requested, with appropriate postage prepaid, or when received in the form of an e-mail or facsimile, and shall be directed to the address, e-mail address or facsimile number as such Director shall designate by notice to the Company. 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, except for amendments to this Agreement, as provided herein. 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.

Section 7.6 Action by Consent of Board. To the extent permitted by Applicable Law and this Agreement, the Board, or any committee of the Board, may act without a meeting so long as a written consent with respect to any action taken in lieu of a meeting is signed by not less than the number of Directors (or committee members) entitled to vote that would be necessary to authorize or take such action at a meeting of the Board (or such committee) at which all Directors (or members of such committee) entitled to vote thereto were present and voted.

Section 7.7 Conference Telephone Meetings. Directors or members of any committee of the Board may participate in a meeting of the Board or such committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting.

Section 7.8 Quorum. A majority of all Directors entitled to vote, present in person or participating in a Board meeting, shall constitute a quorum for the transaction of business, but if

at any meeting of the Board there shall be less than a quorum present, a majority of the Directors entitled to vote and present may adjourn the meeting from time to time without further notice. Except as otherwise required by Applicable Law or this Agreement, all decisions of the Board, or any committee of the Board, shall require the affirmative vote of a majority of all Directors entitled to vote, or of the members of any committee of the Board, respectively. The Directors present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough Directors to leave less than a quorum.

Section 7.9 Committees.

(a) Unless agreed by all Designating Parties with a Veto Interest, the Board may not establish any committees of the Board or delegate any of its responsibilities to any committee.

(b) A majority of any committee, present in person or participating in accordance with Section 7.7, shall constitute a quorum for the transaction of business of such committee.

(c) A majority of any committee may determine its action and fix the time and place of its meetings unless the Board shall otherwise provide. Notice of such meetings shall be given to each member of the committee in the manner provided for in Section 7.5. The Board shall have power at any time to fill vacancies in, to change the membership of, or to dissolve any such committee.

Section 7.10 No Compensation of Directors. No Director shall receive any compensation from the Company for services provided to the Company in its capacity as a Director (including as a committee member), nor shall any Director be entitled to be reimbursed for out-of-pocket costs and expenses incurred in connection with attending meetings of the Board or committees thereof.

Section 7.11 Voting on Certain Matters. The Members shall cooperate in good faith, and shall provide all Voting Support necessary, such that:

(a) The board of directors of SXE GP (the “SXE GP Board”) shall be composed of seven directors. The initial directors to serve on the SXE GP Board are set forth on Exhibit C. So long as (i) BBTS is a Designating Party, BBTS shall have the right to designate four directors to serve on the SXE GP Board (two of whom must be an Independent Director) and (ii) Southcross is a Designating Party, Southcross shall have the right to designate two directors to serve on the SXE GP Board (one of whom must be an Independent Director); provided, however, an Independent Director designated by a Designating Party may be removed upon the vote or consent of a majority of the SXE GP Board (including the approval of the chairman of the SXE GP Board); provided, further, however, that the Designating Party that designated such removed Independent Director shall have the right to designate an Independent Director to replace the removed Independent Director. The seventh member of SXE GP Board and the chairman of the SXE GP Board shall be determined by a vote or consent of a majority of the other directors on the SXE GP Board; provided, however, the initial chairman of the SXE GP Board shall be DWB until the second anniversary of the Effective Date (or until his earlier death

or resignation). There shall always be three Independent Directors on SXE GP Board and if a Designating Party has forfeited its right to designate directors to serve on the SXE GP Board, the remaining Designating Party(ies) shall determine such forfeited directors, and if the Designating Parties cannot agree on such directors within 15 Business Days after the deemed resignation of such forfeited directors, the remaining members of the SXE GP Board, by majority vote or consent, shall determine such forfeited directors.

(b) The initial Chairman of the Board shall be DWB. The position of Chairman of the Board shall be filled on an annually rotating basis by the Designating Parties (provided, prior to a BBTS Distribution (and for so long as BBTS is a Designating Party) BBTS shall designate two successor Chairmen to each one designated by Southcross), such that the next Chairman of the Board after DWB’s initial two-year term shall be designated by BBTS (so long as BBTS is a Designating Party) for a term of one year, his successor shall be designated by BBTS (so long as BBTS is a Designating Party) for a term of one year, his successor shall be designated by Southcross (so long as Southcross is a Designating Party), and so on (and after the BBTS Distribution, such rights of BBTS will be exercised by EIG and TW Aggregator, in succession, so long as such Person is a Designating Person).

(c) The following actions (the “Super Majority Decisions”) of the Company, any Person in the Partnership Group or any of their respective Subsidiaries will require approval of a majority of all Directors entitled to vote and the approval of at least one Director designated by each Designating Party that has a Veto Interest:

(i) approval by the Company (in its capacity as general partner of the Partnership) of any matter set forth in Section 6.2(a) or Section 10.1(a) of the Partnership Agreement;

Section 7.13 Liquidity Event.

(a) Liquidity Event. At any time following 1642 days after the Effective Date and (ii) so long as the Partnership (or any successor thereto) has not effected a Qualified IPO, each Designating Party shall each have the right, at each of their express direction and in each of their sole discretion, to direct the Board to take such actions to effect a Qualified IPO (and, after the fifth anniversary of the Effective Date, a Liquidity Event), upon delivering a written notice thereof to the Board (a “Liquidity Event Notice”) of such decision.

(b) Effecting a Liquidity Event. Upon receipt of a Liquidity Event Notice or approval by the Board of a Liquidity Event, the Company shall initiate a process to effect a Liquidity Event, including without limitation engaging an independent investment banking firm to advise the Board with respect to consummating such Liquidity Event. Such investment banking firm shall be selected by the Board (pursuant to the approval standard required for such

Liquidity Event) in accordance with Section 7.11(c) or Section 7.11(d), as applicable; provided that if the Board does not select an investment banking firm within 30 days after the date that the Liquidity Event Notice is delivered to the Board the investment banking firm shall be selected by the Directors designated by Designating Party who delivered the Liquidity Event Notice. The Company shall, and shall cause the Partnership to, execute such engagement and indemnity agreements as such investment banking firm shall require, and the fees and expenses of such investment banking firm shall be paid by the Partnership. The Board shall use commercially reasonable efforts to consummate a Liquidity Event as soon as practicable following the delivery of a Liquidity Event Notice (provided that the Board shall first use good faith efforts to effect a Qualified IPO prior to effecting any other Liquidity Event unless such Liquidity Event is approved by the Board as a Super Majority Decision pursuant to Section 7.11(c)).

(c) Certain Obligations of the Company and the Members. Upon receipt of a Liquidity Event Notice or approval by the Board of a Liquidity Event, the Company (in its capacity as general partner of the Partnership) shall diligently pursue the consummation of a Liquidity Event in good faith and the Board shall manage the business and affairs of the Company primarily with a view toward the consummation of such Liquidity Event as soon as reasonably practicable following the exercise of such right. Each Member shall, and shall cause its Affiliates to, take all actions, including those set forth in Section 7.13(d), if applicable, reasonably necessary or appropriate to (i) cooperate with the Company (in its capacity as the general partner of the Partnership) in working toward the consummation of a Liquidity Event and (ii) cause its Director designees to act in accordance with this Section 7.13 (including replacing its Director designees, if necessary).

(d) Public Offering. If the Board determines that the Liquidity Event shall be a Public Offering:

(i) each Member agrees that it will, and will cause its Affiliates and any Director appointed by such Member to, and the Company shall:

(A) if the underwriters in any Public Offering request that all Partners hold their Partnership Units for a period of time following the Public Offering, do so and enter into a customary lock-up agreement;

(B) complete and execute all consents, questionnaires, powers of attorney, indemnities, underwriting agreements and other documents as may reasonably be required or advisable in connection with a Public Offering; provided that no such Person shall be required to make any representations or warranties in connection with a Public Offering other than representations and warranties regarding such Person and, if applicable, such Person’s intended method of distribution;

(C) if determined by the Board to be reasonably necessary or appropriate in connection with a Public Offering, do all things reasonably necessary or advisable to effect any recapitalization, reorganization, conversion, contribution and/or exchange of Partnership Units into other equity interests and related reorganization of the Partnership and its Subsidiaries; provided that any

such recapitalization, reorganization, conversion, contribution and/or exchange does not change the relative rights, obligations and preferences of the partners in the Partnership with respect to their ownership of Partnership Units (or its successor), except in accordance with Section 3.11(b) of the Partnership Agreement;

(D) consent to certain additional restrictions on the transfer of Partnership Units or other equity interests in the Partnership (or its successor) which the Board determines may be required in order to permit compliance with the Securities Act or other Applicable Law;

(E) use commercially reasonable efforts to accommodate any such other reasonable actions required by the Commission or similar Governmental Authority to effect the Public Offering; and

(F) make modifications to this Agreement or the Partnership Agreement (or any other agreement then governing the rights and obligations of the Members with respect to the Company or the partners in the Partnership with respect to the Partnership or any of their Subsidiaries or any successor to the Company or the Partnership or any of their Subsidiaries) as are customary and appropriate for companies that conduct a Public Offering, such modifications to be in form and substance reasonably satisfactory to the Board.

(ii) The Company shall be responsible for its own costs, fees and expenses in connection with a Public Offering and shall reimburse the Members and their Affiliates for the reasonable out-of-pocket costs, fees and expenses (excluding underwriting discounts, selling commissions and similar fees) incurred by them in connection with a Public Offering, including the reasonable costs, fees and expenses of one outside counsel for each Member with, a Sharing Ratio of greater than 10% immediately prior to the occurrence of the Liquidity Event.

(iii) If the managing underwriter or the placement agent advises the Partnership, the Company or the Board that the inclusion of securities of the partners in the Partnership requested to be included for sale in a secondary offering in connection with the Public Offering would materially and adversely affect the price, distribution or timing of the offering, then the Partnership shall have the right to exclude all or any portion of such securities of the Partnership from sale in connection with the Public Offering, with such exclusions applied to the partners’ of the Partnership pro rata share (based on the relative percentages of securities to be included in the Public Offering held by the Partners immediately prior to the Public Offering).

(iv) Without limiting Section 7.13(d)(i)(D) above, without the prior written consent of the underwriters managing any Qualified IPO, for a period beginning seven days immediately preceding, and ending on the 180th day following, the effective date of the registration statement used in connection with such offering, no holder of Membership Interests, except pursuant to an effective registration statement as part of such Qualified IPO, shall (i) offer, pledge, sell, contract to sell, sell any option or

contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer, directly or indirectly, any Membership Interests or any securities convertible into or exercisable or exchangeable for Membership Interests or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such Membership Interests, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of such Membership Interests or such other securities, in cash or otherwise; provided, however, that the foregoing restrictions shall not apply to (x) transactions relating to such Membership Interests or securities acquired in open market transactions after the completion of the Qualified IPO, (y) Membership Transfers required in accordance with the terms of this Agreement or the Partnership Agreement or (z) conversions of such Membership Interests or securities into other classes of Membership Interests or securities without change of holder.

(v) The Members shall cooperate in good faith, and shall provide all Voting Support necessary, such that if equity securities are offered to the public in a Qualified IPO or any secondary offering after a Qualified IPO, each Member will be provided with customary registration rights, including demand and piggyback registration rights (pursuant to a Registration Rights Agreement), in any such offering, subject to standard underwriters’ cutback provisions. The registration rights will be assignable by any Designating Party upon any Disposition by such Designating Party of any interest in the Company to any Assignee who holds at least a 10% Membership Interest after giving effect to such Disposition. If any Member desires to exercise or exercises any such registration rights, each non-exercising Member shall cooperate with respect to such registration demand, including providing Voting Support.

INDEMNITY AND LIMITATION OF LIABILITY

Section 9.1 Indemnification; Limitation of Liability.

(a) To the fullest extent permitted by Applicable Law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Company from and against any and all Claims or other amounts arising from any and all Claims, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its 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 9.1, 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 9.1 shall be made only out of the assets of the Company, it being agreed that the Members shall not be personally liable for such indemnification and shall have no obligation to contribute or lend any monies or property to the Company to enable it to effectuate such indemnification. Except as required by the Act, and to the fullest extent such limitation is permitted by Applicable Law, no Member shall owe any fiduciary or other duties (including any duty of loyalty or duty of care) to the Company or the other Members. The Members acknowledge and agree that the foregoing is intended to comply with the provisions of the Act (including Section 18-1101 of the Act) permitting members of a limited liability company to eliminate fiduciary duties.

(b) To the fullest extent permitted by Applicable Law, expenses (including legal fees and expenses) incurred by an Indemnitee shall, from time to time, be advanced by the Company prior to a determination that the Indemnitee is not entitled to be indemnified 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 9.1.

(c) 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, 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 the Indemnitees, the Company and its Affiliates 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 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 9.1, 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”; 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 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) An Indemnitee shall not be denied indemnification in whole or in part under this Section 9.1 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.

(g) 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.

(h) 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 Company or the obligations of the Company 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.

(i) 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.

Section 9.2 Limited 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 Membership Interests in the Company 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, such 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.

(c) 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.

(C) Company property (including cash) shall be distributed among the Members in accordance with Section 6.2; and, to the extent practicable, those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 Days after the date of the liquidation); provided, however, that notwithstanding the foregoing provisions of clauses (A), (B) and (C) immediately above, if the obligation to maintain Capital Accounts has been suspended under Section 13.11 of this Agreement, no allocations shall be made and all Company property shall be distributed to the sole Member.

Section 13.3 Entire Agreement; Superseding Effect. This Agreement constitutes the entire agreement of the Members relating to the Company and the transactions contemplated hereby, and supersedes all provisions and concepts contained in all prior contracts or agreements between the Members with respect to the Company, whether oral or written.

Section 13.4 Effect of Waiver or Consent. Except as otherwise provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Member in the performance by that Member of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Member of

the same or any other obligations of that Member with respect to the Company. Except as otherwise provided in this Agreement, failure on the part of a Member to complain of any act of any Member or to declare any Member in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Member of its rights with respect to that default until the applicable statute-of-limitations period has run.

Section 13.5 Amendment or Restatement. Subject to the right of the Board to amend this Agreement as expressly provided herein, this Agreement may be amended or restated only by a written instrument executed by all Members; provided, however, that notwithstanding anything to the contrary contained in this Agreement, each Member agrees that the Board, without the approval of any Member, may amend any provision of the Delaware Certificate and this Agreement, and may authorize any Officer to execute, swear to, acknowledge, deliver, file and record any such amendment and whatever documents may be required in connection therewith, to reflect any change that does not require consent or approval (or for which such consent or approval has been obtained) under this Agreement or does not adversely affect the rights of the Members.

Section 13.6 Binding Effect. This Agreement is binding on and shall inure to the benefit of the Members and, subject to the restrictions on Dispositions set forth in this Agreement, their respective successors and permitted assigns.

Section 13.7 Governing Law; Severability. This Agreement is governed by and will be construed in accordance with the laws of the State of Delaware, excluding any conflict-of-laws rule or principle (whether under the laws of Delaware or any other jurisdiction) that might refer the governance or the construction of this Agreement to the law of another jurisdiction. If any provision of this Agreement or its application to any Person or circumstance is held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances will not be affected thereby, and such provision will be enforced to the greatest extent permitted by law.

Section 13.8 Consent to Jurisdiction; Waiver of Jury Trial. THE COMPANY AND THE PARTIES HERETO VOLUNTARILY AND IRREVOCABLY SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF TEXAS AND THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA IN DALLAS COUNTY, TEXAS OVER ANY DISPUTE BETWEEN OR AMONG THE PARTIES OR THE COMPANY AND THE PARTIES ARISING OUT OF THIS AGREEMENT, IN EACH CASE OTHER THAN A DISPUTE SUBJECT TO SECTION 13.9, AND THE COMPANY AND EACH PARTY IRREVOCABLY AGREES THAT ALL SUCH CLAIMS IN RESPECT OF SUCH DISPUTE SHALL BE HEARD AND DETERMINED IN SUCH COURTS. THE COMPANY AND THE PARTIES HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH THEY MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH DISPUTE ARISING OUT OF THIS AGREEMENT BROUGHT IN SUCH COURT OR ANY DEFENSE OF INCONVENIENT FORUM FOR THE MAINTENANCE OF SUCH DISPUTE. THE COMPANY AND EACH PARTY AGREES THAT A JUDGMENT IN ANY SUCH DISPUTE MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.

EACH OF THE PARTIES HERETO HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY ACTION OR OTHER PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT.

Section 13.9 Dispute Resolution.

(a) Any dispute, controversy or claim, of any and every kind or type, whether based on contract, tort, statute, regulations, or otherwise, arising out of, connected with, or relating in any way to the Company, its business or to this Agreement or the obligations of the parties hereunder, including without limitation, any dispute as to the existence, validity, construction, interpretation, negotiation, performance, non-performance, breach, termination or enforceability of this Agreement (in each case, a “Dispute”) shall be resolved solely and exclusively in accordance with the procedures specified in this Section 13.9. The parties shall attempt in good faith to settle any Dispute by mutual discussions within 30 days after the date that one party gives notice to the other parties of such a Dispute. If the Dispute is not resolved within such 30 day period, any party may refer the Dispute to arbitration and the Dispute shall be finally settled by arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules then in effect (the “Rules”), and judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. The arbitration shall be held in Dallas, Texas, and presided over by three arbitrators. The party giving notice of the Dispute shall appoint one arbitrator, and the other parties to the Dispute shall appoint one arbitrator. The two appointed arbitrators shall together appoint a third arbitrator. If the appointed arbitrators fail to appoint the third arbitrator within 30 days after their appointment, then the third arbitrator shall be selected in accordance with the Rules. The parties to such Dispute and the Company shall execute such engagement and indemnity agreements as the arbitrators shall require. Notwithstanding this agreement to arbitrate Disputes, any party to a Dispute may apply to a court sitting on Dallas, Texas, for temporary restraining orders, temporary injunctive relief or other interim measures pending arbitration. No court other than a court sitting in Dallas, Texas, shall have authority or jurisdiction to enter temporary restraining orders, temporary injunctive relief or other interim orders pending arbitration, and no party to a Dispute shall make any application for interim orders to any court other than a court sitting in Dallas, Texas. The arbitrators shall award costs, attorneys’ fees and expert witness fees to the prevailing party or parties. The arbitrators may not award indirect, consequential, special or punitive damages, and recovery of any such damages in any Dispute is hereby waived. The award rendered by the arbitrators shall be final and binding, subject only to grounds and procedures for vacating or modifying the award under the Federal Arbitration Act, 9 U.S.C. §§ 1 et. seq.

(b) To the extent that any party hereto (including assignees of any party’s rights or obligations under this Agreement) may be entitled, in any jurisdiction, to claim for itself or its revenues, assets or properties, immunity from service of process, from suit, from the jurisdiction of any court, from an interlocutory order or injunction or the enforcement of the same against its property in such court, from attachment prior to judgment, from attachment in aid of execution of an arbitral award or judgment (interlocutory or final), or from any other legal process, and to the extent that, in any such jurisdiction there may be attributed such immunity (whether claimed or not), each party hereto hereby irrevocably agrees not to claim, and hereby irrevocably waives, such immunity.

(c) This agreement to arbitrate shall be binding upon the successors, assignees and any trustee or receiver of any party.

Section 13.10 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Member shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions.

Section 13.11 Waiver of Certain Rights. Each Member irrevocably waives any right it may have to maintain any action for dissolution of the Company or for partition of the property of the Company.

Section 13.12 Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument.
