(iii)If the Company elects to redeem less than all of the outstanding Series A Preferred Units, the number of Series A Preferred Units to be redeemed shall be determined by the Company, and such Series A Preferred Units shall be redeemed by the Company pro rata across all Holders of Series A Preferred Units (based on such Holders’ respective Series A Preferred Sharing Percentages), with such adjustments as are appropriate, in the Board’s discretion, in order to avoid redemption of fractional Series A Preferred Units; provided, that except for any redemptions made in accordance with Section 5.1(b), each such redemption by the Company shall be for an aggregate amount of Series A Preferred Units involving at least $10,000,000 based on the Base Return as to the Series A Preferred Units the Company desires to redeem (the “Minimum Optional Redemption Amount”) or, if the Base Return as to all of the outstanding Series A Preferred Units is less than the Minimum Optional Redemption Amount, then all outstanding Series A Preferred Units. The Series A Preferred Units not redeemed shall remain outstanding and entitled to all the rights and preferences provided in this Agreement.

Section 4.9Remedial Sale

(a)In addition to, and not in limitation of, the rights set forth in Section 4.8(a), and subject to Section 6.8(b)(xiv), following the occurrence of a Trigger Event, the Series A Preferred Members (acting by Preferred Approval) shall have the right to cause the Company to pursue and consummate a transaction that results in the Base Return with respect to each then outstanding Series A Preferred Unit being paid in cash to the Holder of such Series A Preferred Unit at the consummation of such transaction (a “Remedial Sale”) by delivering written notice thereof (a “Remedial Sale Notice”) to the Company (the Member or Members delivering such notice, collectively the “Initiating Member”). A Remedial Sale may involve a sale of any or all of the equity interests or assets of the Company or its Subsidiaries (other than any sale or other transaction, including a sale of assets of Double E, that (i) would be in violation of the express terms of the Double E LLC Agreement or (ii) would require the consent or approval of the other members of Double E under the Double E LLC Agreement and which is completed without first obtaining such consent or approval).

(b)Following delivery of a Remedial Sale Notice, the Board shall identify, manage, control, negotiate, structure (following consultation with the Series A Preferred Members), approve and otherwise pursue such Remedial Sale, which Remedial Sale may be structured, accomplished and implemented as may be determined by the Board (following consultation with the Series A Preferred Members); provided, however, without limiting any rights of the Holders of Series A Preferred Units set forth in Section 6.8(b)(xiv), the Company shall not enter into any agreement with respect to a Remedial Sale without the prior written approval of the TES Member (which approval shall not be unreasonably withheld, conditioned or delayed). The Board (i) shall manage the business and affairs of the Company primarily with a view toward the consummation of such Remedial Sale as soon as reasonably practicable following the exercise of such right and (ii) shall, and shall cause the Company to, take such actions as reasonably necessary to consummate a Remedial Sale, including (A) engaging a nationally recognized independent investment banker who is reasonably acceptable to the Series A Preferred Members to advise on and conduct such Remedial Sale and (B) Summit Parent agrees to cooperate, and to cause employees of Summit Parent to cooperate, (including by participating in management

presentations, preparing marketing materials and making diligence materials available in an electronic data room) in any marketing process in connection with any proposed Remedial Sale.

(c)If the Company does not consummate a Remedial Sale approved or deemed approved by the Series A Preferred Members within six months of the date of the Remedial Sale Notice, then instead of the Board, the Initiating Member shall (i) engage, on behalf of the Company, an independent investment bank to advise on and conduct the sale and (ii) identify, manage, control, negotiate, structure (following consultation with the Company and the other Series A Preferred Members) and otherwise pursue such Remedial Sale, which Remedial Sale may be structured, accomplished and implemented as may be determined by the Initiating Member (following consultation with the Company and the other Series A Preferred Members). The Series A Preferred Members shall keep the Board reasonably informed of the Remedial Sale process. The Board (A) shall manage the business and affairs of the Company primarily with a view toward the consummation of such Remedial Sale as soon as reasonably practicable following the exercise of such right and (B) shall, and shall cause the Company to, take such actions as the Initiating Member reasonably requests in connection with any proposed Remedial Sale.

(d)If the Initiating Member delivers a Remedial Sale Notice in accordance with Section 4.9(a), each Member shall (i) take all actions reasonably necessary to cooperate with the Initiating Member, the other Series A Preferred Members, the Company and the Board in working toward the consummation of a Remedial Sale, (ii) raise no objections against any Remedial Sale that (x) in the case of Section 4.9(b) is approved by the Board and the TES Member or (y) in the case of Section 4.9(c) is approved by the Initiating Member and (iii) to the extent necessary or desirable to effect the consummation of such Remedial Sale, that (x) in the case of Section 4.9(b) is approved by the Board and the TES Member, vote for and consent to, such Remedial Sale or (y) in the case of Section 4.9(c) is approved by the Initiating Member, vote for and consent to, and cause its appointee(s) to the Board to vote for and consent to, such Remedial Sale; provided, however, if the Company receives more than one offer to consummate a Remedial Sale, the Holders of Series A Preferred Units shall be deemed to have approved the offer for a Remedial Sale that results in the highest enterprise value of the Company, subject to the satisfaction of the requirements set forth in this Section 4.9. If the Remedial Sale is structured as a (x) merger, consolidation or sale of assets, each Member shall waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger, consolidation or sale of assets or (y) sale of Units, each Member shall agree to sell all of its Units or rights to acquire Units on the terms and conditions reasonably approved by the Initiating Member or in the case of Section 4.9(b), the Board and the TES Member, and that are customary for such transaction. Notwithstanding anything in this Section 4.9 to the contrary, in connection with any Remedial Sale, without the prior written consent of such Holder of Series A Preferred Units in no event shall any Holder of Series A Preferred Units be subject to any post-closing obligations, including indemnification obligations, or to any non-compete, no contact, non-solicit or other restrictive covenants (other than a confidentiality covenant on terms reasonably acceptable to each Holder of Series A Preferred Units), nor shall Summit Parent or its Subsidiaries (other than the Company and its Subsidiaries) be subject to any post-closing restriction on its ability to engage in the oil and natural gas gathering and processing business without the prior written consent of Summit Parent.

(e)In any Remedial Sale, the consideration received by the Company shall be allocated and distributed to each Member in accordance with Section 10.2(b) after all the liabilities of the Company have been satisfied in full or provided for.

(f)The Company shall bear the costs and expenses of any Remedial Sale to the extent such costs and expenses are incurred for the benefit of all Holders and are not otherwise paid by the acquiring party.

(g)For the avoidance of doubt, notwithstanding anything herein to the contrary, in no event shall TES Member be required to consent to the consummation of any Remedial Sale that does not result in the satisfaction of the Base Return in cash or that imposes obligations on TES Member after the closing of such Remedial Sale, nor shall the Company consummate any such Remedial Sale without the consent of TES Member.

Section 4.10Undrawn Commitment Amount

. The Company shall pay to each Series A Preferred Member, within 21 days after the end of each fiscal quarter, an amount (the “Undrawn Commitment Amount”) equal to the Undrawn Commitment Rate of such Series A Preferred Member’s Undrawn Portion. The Undrawn Commitment Amount may, at the discretion of the Board, be paid to each Series A Preferred Member (a) in cash or (b) by issuing a number of additional Series A Preferred Units in an amount equal to the quotient of (i) the Undrawn Commitment Amount divided by (ii) the Series A Preferred Issue Amount to such Series A Preferred Member (the “Undrawn Commitment Units”); provided that if, with respect to any fiscal quarter, the Company elects to satisfy any Undrawn Commitment Amount using both the forms of consideration described in the preceding clauses (a) and (b), the Company shall pay each Series A Preferred Member pro rata portions of each such form of consideration (based on each such Series A Preferred Member’s Undrawn Commitment Amount in respect of the relevant fiscal quarter).

Article V
DISTRIBUTIONS AND ALLOCATIONS

Section 5.1Distributions

(a)Generally. Subject to Section 5.1(b), Section 5.1(c), Section 5.2 and Article X, all Available Cash shall be retained by the Company unless otherwise agreed by the Board and consented to by Preferred Approval in accordance with Section 6.8(b)(iii).

(b)Distributions of Available Cash.

(i)The Company shall not make any distributions among the Members except as provided in Section 5.1(c), Section 5.2, and Article X; provided that, (A) the Company may make distributions among the Members pursuant to this Section 5.1(b) following the date on which there are no Series A Preferred Units outstanding; and (B) commencing with the first full fiscal quarter following the fiscal quarter in which the In-Service Date occurs and so long as all distributions required to be paid by the Company in accordance with Section 5.1(c) have been timely paid in accordance with Section 5.1(c), the Board may elect to cause the Company to make distributions of Available Cash in

respect of any fiscal quarter of the Company on the Series A Preferred Distribution Payment Date for such fiscal quarter (the “Quarterly AC Distribution Date”) as follows:

(A)if no Funded Indebtedness of the Company or its Subsidiaries is outstanding on the applicable Quarterly AC Distribution Date, then the Company may make distributions of Available Cash with respect to the relevant fiscal quarter (1) __% to redeem, on a pro rata basis, the Series A Preferred Units in accordance with Section 4.8(b) (except that the Minimum Optional Redemption Amount shall not apply) and (2) __% to the Holders of Common Units in accordance with Section 5.1(b)(iii); and

(B)if (1) Funded Indebtedness of the Company or its Subsidiaries is outstanding on the applicable Quarterly AC Distribution Date and (2) the Leverage Ratio is ___ or below, then the Company may make distributions of Available Cash with respect to the relevant fiscal quarter (a) __% to redeem, on a pro rata basis, the Series A Preferred Units in accordance with Section 4.8(b) (except that the Minimum Optional Redemption Amount shall not apply) and (b) __% to the Holders of Common Units in accordance with Section 5.1(b)(iii).

(ii)In no event shall distributions made in accordance with Section 5.1(b)(i) in any fiscal quarter exceed the Maximum Quarterly AC Distribution Amount without Preferred Approval.

(iii)Subject to Section 5.1(b)(i), the Board shall, following the end of each fiscal quarter, determine the amount of Available Cash distributable to the Holders of Common Units in accordance with Section 5.1(b)(i), if any, and promptly, on or following the Series A Preferred Distributions Payment Date for such fiscal quarter, distribute any such Available Cash to the Holders of Common Units pro rata (based on the Common Unit Sharing Percentages of such Holders).

(c)Distributions on Series A Preferred Units.

(i)From and after the Effective Date, distributions at the Series A Preferred Distributions Rate (or the Series A Preferred Distributions Rate plus the Step-Up Rate pursuant to either (A) Section 5.1(c)(iii) or (B) the last sentence of Section 5.2) shall accrue on each Series A Preferred Unit (the “Series A Preferred Distributions”). Series A Preferred Distributions shall accrue and accumulate from day to day, whether or not declared, and shall be cumulative. When, as and if declared by the Board, subject to the Company’s right to make Series A Non-Cash Distribution Elections during the PIK Period as set forth in Section 5.1(c)(ii), Series A Preferred Distributions shall be payable in cash, in arrears on each Series A Preferred Distributions Payment Date for the fiscal quarter ending immediately prior to such Series A Preferred Distributions Payment Date (or with respect to the first applicable Series A Preferred Distributions Payment Date, for the period commencing on the Effective Date and ending on the last day of the fiscal quarter during which the Effective Date occurs) from the assets of the Company out of funds legally permitted to be distributed pursuant to the Act for payment. Except as provided in Section

5.1(b), this Section 5.1(c), Section 5.2 and Article X, the Company shall not declare, pay or set aside any distributions or dividends on any Units (other than Series A Preferred Units) or effect any repurchase or redemption of, any Units or other Interests of the Company (other than redemptions of Series A Preferred Units in accordance with Section 4.8), in either case, so long as any Series A Preferred Units remain issued and outstanding.

(ii)Notwithstanding anything to the contrary in this Section 5.1(c), the Company may, at the sole election of the Board, with respect to any Series A Preferred Distribution accrued in respect of any fiscal quarter (or portion thereof for which a Series A Preferred Distribution is due) until the expiration of the PIK Period, elect (a “Series A Non-Cash Distribution Election”) to have up to 100% of the amount that would have been payable in cash if such distribution had been a cash distribution to instead be paid through the issuance to the Series A Preferred Member of a number of Series A Preferred Units (the “PIK Units”) equal to the quotient resulting from the division of the amount of the Series A Preferred Distribution for such quarter by the Series A Preferred Issue Amount, which issuance shall be effective as of the first day of the fiscal quarter immediately following the fiscal quarter in respect of which such payment is due in lieu of paying such portion of such accrued Series A Preferred Distribution in cash. Notwithstanding anything in this Agreement to the contrary, for any fiscal quarter with respect to which there is any unpaid amount of any Series A Preferred Distribution, such quarter shall be deemed a fiscal quarter with respect to which the Company made a Series A Non-Cash Distribution Election.

(iii)If the Company fails to pay in cash in full all or any part of any Series A Preferred Distribution when due for any quarter following the PIK Period, then from and after the first day of the immediately following fiscal quarter and continuing until such failure is cured by payment in full in cash of all arrearages (for the avoidance of doubt, including arrearages attributable to the Step-Up Rate), (A) the Series A Preferred Distributions shall accrue at the Series A Preferred Distributions Rate plus the Step-Up Rate and (B) the amount of such accrued but unpaid cash distributions shall constitute arrearages that shall accrue and accumulate (and compound quarterly) at the Series A Preferred Distributions Rate plus the Step-Up Rate until paid. Notwithstanding anything to the contrary in this Agreement, the portion of such arrearages attributable to the Step-Up Rate shall not be deemed distributions paid by the Company to the Holders of Series A Preferred Units for purposes of the ROI and IRR calculations as used in the calculation of the Base Return, but instead shall be deemed liquidated damages (and not a penalty) paid by the Company to the Holders of Series A Preferred Units as a return of a separate portion of the Base Return.

(d)Payments of Cash Distributions. Payment of all cash distributions made by the Company to a Member shall be made by wire transfer of immediately available funds in accordance with such written instructions to the Company as may be provided by such Member from time to time.

Section 5.2Tax Distributions

. To the extent (a) the Board determines that the Company has Available Cash and (b) such distributions are permitted by any credit or financing agreements to which the Company or any of its Subsidiaries is a party, the Board shall cause the

Company to make distributions to each Holder in the amount, if positive, of (X) such Holder’s Cumulative Assumed Tax Liability as of each Tax Distribution Date minus (Y) the cumulative cash distributions made to such Holder pursuant to Section 5.1 and this Section 5.2. If, as of any Tax Distribution Date, the Company either (a) has insufficient Available Cash or (b) is not permitted under any credit or financing agreement to make distributions in an amount equal to the aggregate of the Cumulative Assumed Tax Liabilities of the Holders of Series A Preferred Units for such Tax Distribution Date (if the Company is not permitted to make tax distributions pursuant to clauses (a ) or (b), a “Tax Distribution Default”), then the Company shall make distributions to the Holders of Series A Preferred Units pursuant to this Section 5.2 to the extent of such Available Cash or to the extent permitted under such agreement, as applicable. Notwithstanding anything in this Section 5.2 to the contrary, no Holder shall have any obligation to make any Capital Contribution to fund any distributions described in this Section 5.2. Any distribution made pursuant to this Section 5.2 shall be treated as an advance against the next distribution payable to such Holder pursuant to Section 5.1, as applicable and shall reduce such distributions. If the Company is in a Tax Distribution Default for any portion of any fiscal quarter during the PIK Period, the Series A Preferred Distributions Rate for such fiscal quarter shall be the Series A Preferred Distributions Rate plus the Step-Up Rate (and, notwithstanding anything to the contrary in this Agreement, such portion of distributions attributable to the Step-Up Rate shall not, to the extent distributed by the Company by issuing additional Series A Preferred Units, be deemed distributions paid by the Company to the Holders of Series A Preferred Units for purposes of the ROI and IRR calculations as used in the calculation of Base Return, but instead shall be deemed liquidated damages (and not a penalty) paid by the Company to the Holders of Series A Preferred Units).

Section 5.3Allocations

(a)Profits and Losses. Except as otherwise provided in this Agreement, Profit and Loss of the Company will be allocated among the Members in a manner such that, after giving effect to the special allocations set forth in Section 5.3(b) and Section 5.3(c), the Capital Account balance of each Member, immediately after making such allocation, is, as nearly as possible, equal (proportionately) to their Target Capital Account. “Target Capital Account” with respect to a Member or Series A Preferred Unit means (i) the distributions that would be made to such Member or in respect of such Series A Preferred Unit pursuant to Section 5.1 and Section 10.2 if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Fair Market Value, all Company liabilities were satisfied (limited with respect to each nonrecourse liability to the Fair Market Value of the assets securing such liability) and the net assets of the Company were distributed in accordance with Section 10.2 to the Members immediately after making such allocation (but determined without regard to clause (a) of the definition of “Base Return”), minus (ii) such Member’s or Unit’s share of Company Minimum Gain and Member Minimum Gain, computed immediately prior to the hypothetical sale of assets. The entitlement to distributions pursuant to this Agreement (including pursuant to a redemption or dissolution) of a Holder of Series A Preferred Units shall not be treated, for U.S. federal income tax purposes, as a guaranteed payment for the use of capital pursuant to Section 707(c) of the Code or as a capital shift for U.S. federal income tax purposes, except to the extent that a distribution is paid in cash to a Holder of Series A Preferred Units and the Company has insufficient Profit and items of gross income and gain to allocate to a Holder of Series A Preferred Units to cause such Member’s Capital Account to reflect the amount such Member actually receives, in which case such excess distribution shall

be treated for U.S. federal income tax purposes as a guaranteed payment for the use of capital pursuant to Code Section 707(c).

(b)Regulatory Allocations. Notwithstanding the foregoing provisions of Section 5.3(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 a Company taxable year, then each Holder will be allocated items of Company income and gain for such taxable year (and, if necessary, for subsequent years) in an amount equal to such Holder’s share of the net decrease in Company Minimum Gain, determined in accordance with Treasury Regulations Section 1.704-2(g)(2). This Section 5.3(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 taxable year, each Holder 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 taxable year (and, if necessary, subsequent years) in an amount equal to such Holder’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 Sections 1.704-2(g)(2) and (j)(2)(ii). This Section 5.3(b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement of Treasury Regulation Section 1.704-2(i)(4) and will be interpreted consistently therewith.

(iii)Qualified Income Offset. If any Holder 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 and gain will be allocated to all such Holders (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 Holder as quickly as possible; provided, that an allocation pursuant to this Section 5.3(b)(iii) shall be made if and only to the extent that such Holder would have an Adjusted Capital Account deficit after all other allocations provided for in this Article V have been tentatively made as if this Section 5.3(b)(iii) were not in this Agreement. It is intended that this Section 5.3(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)Limitation on Allocation of Net Loss. If the allocation of Losses to a Holder as provided in Section 5.3(a) would create or increase an Adjusted Capital Account deficit, there will be allocated to such Holder only that amount of Losses as will not create or increase an Adjusted Capital Account deficit. The Losses that would, absent the application of the preceding sentence, otherwise be allocated to such Holder will be allocated to the other Holders in accordance with their relative proportion of Units, subject to the limitations of this Section 5.3(b)(iv).

(v)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 as the result of a distribution to a Holder in complete liquidation of its Interest, 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 Holders 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 Holders to whom such distribution was made in the event that Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

(vi)Nonrecourse Deductions. The Nonrecourse Deductions for each taxable year of the Company will be allocated to the Common Units in proportion to their Common Unit Sharing Percentages.

(vii)Member Nonrecourse Deductions. The Member Nonrecourse Deductions will be allocated each year to the Holder 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.

(c)Allocations with Respect to Series A Preferred Units. Notwithstanding any other provision of this Section 5.3:

(i)Items of Company gross income and gain for the taxable period shall be allocated to the Holders of Series A Preferred Units in proportion to, and to the extent of, an amount equal to the sum of (A) the Series A Preferred Distributions that are paid in cash with respect to the Series A Preferred Units for such period; (B) after taking into account clause (A), the excess, if any, of (X) the Series A Preferred Issue Amount with respect to such Holder’s Series A Preferred Units, over (Y) such Holder’s existing Capital Account balance in respect of such Series A Preferred Units, until the Capital Account balance of each such Holder in respect of its Series A Preferred Units is equal to the Series A Preferred Issue Amount with respect to such Holder’s Series A Preferred Units; and (C) to the extent such allocation would not create or increase a Loss, additional items of gross income and gain such that the Capital Account balance in respect of each Series A Preferred Unit, immediately after making such allocation, is, as nearly as possible, equal (proportionately) to its Target Capital Account.

(ii)Without duplication of allocations under (c)(i) above, items of Company gross income shall be allocated to the Holders of Series A Preferred Units, pro rata, until the aggregate amount of gross income allocated to each Holder of Series A Preferred Units pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Losses allocated to such Member pursuant to Section 5.3(a) for all previous taxable years.

(iii)If (A) (1) a redemption pursuant to Section 4.8 occurs, (2) a Remedial Sale occurs, or (3) the Company liquidates or dissolves pursuant to Section 10.2 (each, a “Series A Allocation Event”), and (B) after having made all other allocations provided for in this Section 5.3 for the taxable period in which the Series A Allocation Event occurs, the per unit Capital Account of each Series A Preferred Unit does not equal the amount each Holder of Series A Preferred Units receives pursuant to such Series A Allocation Event, then items of gross income, gain, loss and deduction for such taxable period shall be allocated among the Members in a manner determined appropriate by the Board so as to cause, to the maximum extent possible, the per unit Capital Account of each Series A Preferred Unit to equal the amount received with respect to such Series A Preferred Units (and no other allocation pursuant to this Agreement shall reverse the effect of such allocations). Notwithstanding anything to the contrary in this Agreement, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the balances described above, items of gross income and gain that would otherwise be included in Profit or Loss, as the case may be, for the taxable period in which the Series A Allocation Event occurs, may be reallocated from the Members holding Units other than Series A Preferred Units to Members holding Series A Preferred Units. If a Series A Allocation Event occurs on or before 60 days after the end of the taxable period in which such Series A Allocation Event occurs and the reallocation of items for such taxable period as set forth above in this Section 5.3(c) fails to achieve the per unit Capital Accounts described above, then items of gross income, gain, loss and deduction for such prior taxable period shall be reallocated among all Members in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 5.3(c), cause the per unit Capital Account for each Series A Preferred Unit to equal the amount received with respect to a Series A Preferred Unit at the time of a Series A Allocation Event.

(iv)If, after taking into account all other provisions of this Section 5.3 other than this Section 5.3(c)(iv), (A) a Series A Allocation Event occurs on or before the date prescribed by Law for the filing of the Company’s federal income tax return for the taxable period immediately prior to the taxable period in which the Series A Allocation Event occurs and (B) the reallocation of items for the taxable period in which the Series A Allocation Event occurs as set forth in this Section 5.3(c) fails to achieve the per unit Capital Account described in this Section 5.3(c), then for US federal income tax purposes, any deficit in such per unit Capital Account described in this Section 5.3(c) will be treated as a guaranteed payment for the use of capital within the meaning of Code Section 707(c).

(d)Tax Allocations.

(i)Except as provided in Section 5.3(d)(ii), 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 in the same manner as the correlative item of “book” income, gain, loss, deduction or credit is allocated pursuant to this Article V.

(ii)Tax items with respect to Company assets that are contributed to the Company (or deemed contributed to the Company, consistent with Revenue Ruling 99-5,

1991 C.B. 434) with a Gross Asset Value that varies from its basis in the hands of the contributing Holder immediately preceding the date of contribution will be allocated between the Holders for federal 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 using the “remedial method” under Treasury Regulation Section 1.704-3(d). If the Gross Asset Value of any Company asset is adjusted pursuant to the definition of “Gross Asset Value” in this Agreement, 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 using the “remedial method” under Treasury Regulation Section 1.704-3(d).

(iii)Allocations pursuant to this Section 5.3(d) 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 Holder’s Capital Account or share of Profits, Losses and any other items or distributions pursuant to any provision of this Agreement.

(e)Other Provisions.

(i)For any Tax Year or other period during which any part of any Interest in the Company is Transferred between the Holders 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 Board.

(ii)For purposes of determining a Holder’s proportional share of the Company’s “excess nonrecourse liabilities” within the meaning of Treasury Regulations Section 1.752-3(a)(3), each Holder’s interest in Profits shall be in the same proportion as Nonrecourse Deductions are allocated to such Holder, as provided in Section 5.3(b)(vi).

(iii)The allocations set forth in Section 5.3 are intended to comply with the Code and Treasury Regulations. If the Board determines that the allocations to a Member are not in compliance with the Code and Treasury Regulations, the Board is authorized to make any appropriate adjustments; provided that the Board shall make no adjustments without first notifying the Members, providing an explanation of the proposed adjustments and permitting the Members to discuss the proposed adjustments with the Board; provided, further that the Board may not make any adjustments that would have a disproportionate and adverse impact on the Series A Preferred Members without Preferred Approval.

(f)Valuation; Revaluation. Except as otherwise specifically provided in this Agreement, valuations for purposes of allocation of tax items will be made by the Board or, in the discretion of the Board, by independent third parties appointed by the Board and deemed qualified by the Board to render an opinion as to the value of the Company’s assets, using customary and

industry accepted valuation techniques and taking into account such information relating to the investments, assets and liabilities of the Company as the Board or independent third party, as the case may be, as are customary and reasonable and each such valuation shall be determined without application of any minority, illiquidity, or other discount.

Section 5.4Withholding

. The Company may withhold distributions or portions thereof if it is required to do so by any applicable rule, regulation, or Law, and each Holder hereby authorizes the Company to withhold from or pay on behalf of or with respect to such Holder any amount of federal, state, local or foreign taxes that the Board determines that the Company is required to withhold or pay with respect to any amount distributable or allocable to such Holder pursuant to this Agreement. If the Company determines that it is required to withhold any amount payable to a Holder, the Company shall use commercially reasonable efforts to provide such Holder at least three Business Days prior to the date the applicable payment is scheduled to be made with (a) written notice of the intent to deduct and withhold, which shall include a copy of the calculation of the amount to be deducted and withheld, and (b) a reasonable opportunity for such Holder to provide forms or other evidence that would exempt such amounts from withholding (or reduce such withholding). Any amounts withheld pursuant to this Section 5.4 will be treated as having been distributed to such Holder. To the extent that the cumulative amount of such withholding for any period exceeds the distributions to which such Holder is entitled for such period, the amount of such excess will be considered a loan from the Company to such Holder, with interest accruing at 2% plus the Interest Rate. Such loan may, at the option of the Board, be satisfied (a) out of distributions to which such Holder would otherwise be subsequently entitled, or (b) by the immediate payment in cash to the Company of such excess amount.

Article VI
MANAGEMENT

Section 6.1Management

Section 6.3Officers

. The Board may, from time to time, designate one or more Persons to be Officers of the Company, with such titles as the Board may assign to such Persons. No Officer need be a Member or a resident of the State of Delaware. Officers so designated will have such authority and perform such duties as the Board may, from time to time, delegate to them and,

unless otherwise specified by the Board, will have the authority and responsibilities generally held by officers of a Delaware corporation holding the same titles. Any number of offices may be held by the same Person. Each Officer shall have such fiduciary duties to the Company and its Members that an officer of a Delaware corporation having a corresponding title would have. The salaries or other compensation, if any, of the Officers and agents of the Company will be fixed from time to time by the Board. Any Officer may resign as such at any time. Such resignation will be made in writing and delivered to the Board and will take effect at the time specified therein, or if no time be specified, at the time of its receipt by the Board.

Section 6.4Waiver of Fiduciary Duties; Indemnification; Limitation of Liability

(b)Other than any action or failure to act in breach of Section 6.2(n) (which such breach would, for the avoidance of doubt, constitute a breach of the fiduciary duty of the Directors acting or failing to act in breach of Section 6.2(n)), no Director shall have any fiduciary or other duty to the Company, any Member or any other Person that is a party to or is otherwise bound by this Agreement other than the implied contractual covenant of good faith and fair dealing, and no Director shall be liable in damages to the Company, any Member or any other Person that is a party to or is otherwise bound by this Agreement by reason of, or arising from or relating to the operations, business or affairs of, or any action taken or failure to act on behalf of, the Company, except to the extent that it is determined by a final, non-appealable order of a court of competent jurisdiction that any of the foregoing was caused by a bad faith violation of the implied contractual covenant of good faith and fair dealing, or actual (and not constructive) fraud or willful misconduct, or, with respect to any criminal action or proceeding, that such Director acted with knowledge that its conduct was unlawful.

(c)Notwithstanding any other provision of this Agreement, to the extent that any provision of this Agreement purports or is interpreted (i) to have the effect of replacing, restricting or eliminating the duties that might otherwise, as a result of Delaware or other applicable Law, be owed by any Director or Member to the Company, the Members, any other Person who acquires an interest in the Company or any other Person who is bound by this Agreement or (ii) to constitute a waiver of such duties by the Company, the Members, any other Person who acquires

an interest in the Company or any other Person who is bound by this Agreement or a consent by any of the foregoing to any such replacement, restriction or elimination, such provision shall be deemed to have been approved by the Company, all the Members, each other Person who acquires an interest in the Company and each other Person who is bound by this Agreement.

(d)Each Director, in performing its obligations under this Agreement, shall be entitled to act or omit to act considering only such factors as such Director chooses to consider, and any action of such Director or failure to act, taken or omitted in good faith reliance on this Section 6.4 shall not constitute a breach of any duty (including any fiduciary duty, all of which are disclaimed to the extent provided in Section 6.4(b)) on the part of such Director to the Company or any other Member. Notwithstanding anything to the contrary in this Agreement, to the fullest extent permitted by applicable Law, and without limiting the foregoing, (i) subject to the provisions of this Agreement, each Director may grant or withhold approval, in such Director’s sole and absolute discretion, with respect to any action before such Director on which it is entitled to grant approval and (ii) with respect to any action before a Director on which such Director is entitled to vote or grant approval, to the fullest extent permitted by applicable Law, such Director shall be entitled to consider only such interest and factors as it desires, including its own interests or the interest of such Director or its Affiliates, and shall have no duty (including any fiduciary or quasi-fiduciary duty) or obligation to give any consideration to any interest of or factors affecting the Company, the Members or any of their respective Subsidiaries, Affiliates or any other Person.

IT IS THE EXPRESS INTENT OF THE COMPANY THAT THE FOREGOING INDEMNITY SHALL BE APPLICABLE TO ANY LOSS THAT HAS RESULTED FROM OR IS ALLEGED TO HAVE RESULTED FROM THE ACTIVE OR PASSIVE OR THE SOLE, JOINT, OR CONCURRENT NEGLIGENCE OF THE INDEMNITEE.

(f)To the maximum extent permitted by applicable Law, expenses incurred by an Indemnitee in defending any proceeding (except a proceeding by or in the right of the Company), will be paid by the Company in advance of the final disposition of the proceeding, upon receipt of a written undertaking by or on behalf of such Indemnitee to repay such amount if

such Indemnitee is adjudicated to be ineligible for indemnification as authorized pursuant to this Section 6.4.

(j)The Company will have the power to purchase and maintain insurance on behalf of any Indemnitee against any liability asserted against such Indemnitee and incurred by such Indemnitee in any such capacity, or arising out of such Person’s status as a Indemnitee, whether or not the Company would have the power to indemnify such Indemnitee against such liability under the provisions of this Section 6.4 or under applicable Law. The Company will obtain and fully pay a customary directors’ and officers’ insurance policy (“D&O Insurance”) covering the Directors and Officers of the Company (including the Series A Preferred Director and Board Observer). The Company will cause the D&O Insurance to remain in effect for all periods during with any Series A Preferred Units are outstanding and shall ensure that the Board Observer and Series A Preferred Director are named insureds and covered by customary “Side A” coverage under the D&O Insurance and, in each case, are entitled to terms, conditions, retentions and limits of liability thereunder that are at least as favorable as the those provided under the directors’ and officers’ insurance coverage provided to any Summit Director by the Company or by Summit Parent to its directors.

(k)Notwithstanding anything in this Agreement to the contrary, nothing in this Section 6.4 or Section 6.7 shall (i) limit or waive any claims against, actions, rights to xxx, other remedies or other recourse the Company, any Member or any other Person may have against the any Member, Director, Officer or other Covered Person for a breach of contract claim relating to any binding agreement to which such Covered Person is a party (including, where applicable, this Agreement or any of the Other Transaction Documents) or (ii) entitle any such Covered Person to be indemnified or advanced expenses with respect to such a breach.

Indemnitee may have to seek or obtain indemnification or advancement of expenses from any other Person or any of its Affiliates (“Other Indemnitor”) or from any insurance policy for the benefit of such Indemnitee, and any obligation of any Other Indemnitor to provide advancement or indemnification for all or any portion of the same expenses, liabilities, judgments, penalties, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such expenses, liabilities, judgments, penalties, fines and amounts paid in settlement) incurred by such Indemnitee and any rights of recovery of such Indemnitee under any insurance policy for the benefit of such Indemnitee are secondary; and
