A Member may own one or more classes of Membership Interests, and the ownership of one class of Membership Interests shall not affect the rights, privileges, preferences or obligations of a Member with respect to the other class of Membership Interests owned by such Member. Any reference herein to a holder of a class of Membership Interests shall be deemed to refer to such holder only to the extent of such holder’s ownership of such class or series of Membership Interests.

(b) Members. At the Effective Date, and upon the execution and delivery by the Members of this Agreement and the consummation of the transaction contemplated by the Master Reorganization Agreement, the Company issued:

(i) Class A Units to LGN pursuant to the transactions contemplated in the Master Reorganization Agreement, and LGN was admitted to the Company as a Class A Member;

(ii) Class A Units to LGN Sub pursuant to the transactions contemplated in the Master Reorganization Agreement, and LGN Sub was admitted to the Company as a Class A Member;

(iii) Class A Units to BCP 8 pursuant to the transactions contemplated in the Master Reorganization Agreement, and BCP 8 was admitted to the Company as a Class A Member; and

(iv) Class B Units to Legence Parent pursuant to the transactions contemplated in the Master Reorganization Agreement, and Legence Parent was admitted to the Company as a Class B Member.

(c) Additional Persons may be admitted to the Company as new Members only as provided in this Agreement.

(d) Amendments to Exhibit A. The Membership Interests and respective Percentage Interests held by each Member are set forth on Exhibit A hereto. Exhibit A shall be amended from time to time to reflect changes and adjustments resulting from (i) the admission of any new Member, (ii) any Transfer of Membership Interests in accordance with this Agreement and/or (iii) any Capital Contributions made, changes to Percentage Interests or additional Membership Interests issued, in each case as permitted by this Agreement (provided, that a failure to reflect such change or adjustment on

13

Exhibit A shall not prevent any otherwise valid change or adjustment from being effective). Any reference in this Agreement to Exhibit A shall be deemed a reference to the Exhibit A as amended in accordance with this Section 3.1(d) and in effect from time to time.

(e) Splits, Distributions and Reclassifications. The Company shall not in any manner subdivide (by any split, distribution, reclassification, recapitalization or otherwise) or combine (by reverse split, reclassification, recapitalization or otherwise) the outstanding Class A Units or Class B Units unless an identical event is occurring with respect to the Class A Stock or Class B Stock, respectively, in which event the Class A Units or Class B Units, as applicable, shall be subdivided or combined concurrently with and in the same manner as the Class A Stock or Class B Stock, unless, in each case, such action is necessary to maintain at all times a one-to-one ratio between either the number of Class A Units owned, directly or indirectly, by LGN and the number of shares of Class A Stock or the number of Class B Units owned by Members (other than LGN and its Subsidiaries) and the number of outstanding shares of Class B Stock. This Section 3.1(e) shall be applied to maintain at all times (i) a one-to-one ratio between the number of Class A Units owned, directly or indirectly, by LGN and the number of outstanding shares of Class A Stock or (ii) a one-to-one ratio between the number of Class B Units owned by Members (other than LGN and its Subsidiaries) and the number of outstanding shares of Class B Stock.

(f) Cancellation of Class A Stock and Class A Units. At any time a share of Class A Stock is redeemed, repurchased, acquired, cancelled or terminated by a Class A Member, the Company shall redeem, repurchase, acquire, cancel or terminate, as applicable, one Class A Unit (or other economically equivalent equity interest) registered in the name of such Class A Member upon the same terms and for the same price as the Class A Stock so that the aggregate number of Class A Units held by such Class A Member at all times equals the number of shares of Class A Stock issued outstanding.

(g) Offerings of Class A Stock. At any time LGN issues a share of Class A Stock or other equity security other than pursuant to an Incentive Plan, the net proceeds received by LGN with respect to such share of Class A Stock or equity security, if any, shall be concurrently directly or indirectly contributed to the Company, and the Company shall issue to LGN or one of LGN’s wholly owned subsidiaries one Class A Unit (or in the event of an issuance of other equity securities, the corresponding equivalent number of Class A Units) registered in the name of LGN or one of LGN’s wholly owned subsidiaries; provided, however, that if LGN issues any shares of Class A Stock in order to purchase or fund the purchase from a Member of a number of Class B Units (and the corresponding number of shares of Class B Stock) equal to the number of shares of Class A Stock so issued, then such purchased Class B Units shall automatically convert into Class A Units and the Company shall not issue any new Class A Units in connection therewith.

(h) Incentive Plan Awards. At any time LGN issues one or more shares of Class A Stock pursuant to an Incentive Plan, whether such share or shares are issued upon exercise of an option, settlement of a restricted stock unit, as restricted stock or otherwise, the Company shall issue to LGN a corresponding number of Class A Units; provided, that LGN shall be required to concurrently contribute the net proceeds (if any) received by LGN from or otherwise in connection with such corresponding issuance of one or more shares of Class A Stock, including the exercise price of any option exercised to the Company. If any such shares of Class A Stock so issued by LGN in connection with an Incentive Plan are subject to vesting or forfeiture provisions, then the Class A Units that are issued by the Company to LGN in connection therewith in accordance with the preceding provisions of this Section 3.1(h) shall be subject to vesting or forfeiture on the same basis (and, if any of such shares of Class A Stock vest or are forfeited, then a corresponding number of the Class A Units issued by the Company in accordance with the preceding provisions of this Section 3.1(h) shall automatically vest or be forfeited). Any cash or property held by either LGN or the Company or on either’s behalf in respect of dividends paid on restricted Class A Stock that fails to vest shall be returned to the Company upon the forfeiture of such restricted Class A Stock.

14

(i) Issuances of Debt Securities. If at any time LGN or any of its Subsidiaries (other than the Company and its Subsidiaries) issues Debt Securities, LGN or such Subsidiary shall transfer to the Company (in a manner to be determined by the Managing Member in its reasonable discretion) the proceeds received by LGN or such Subsidiary in exchange for such Debt Securities in a manner that directly or indirectly burdens the Company with the repayment of the Debt Securities.

3.2 Number of Members. The number of Members of the Company shall never be fewer than one.

3.3 Representations and Warranties. Each Member hereby represents, warrants and acknowledges to the Company that: (a) such Member has such knowledge and experience in financial and business matters and is capable of evaluating the merits and risks of an investment in the Company and is making an informed investment decision with respect thereto; (b) such Member is acquiring interests in the Company for investment only and not with a view to, or for resale in connection with, any distribution to the public or public offering thereof; and (c) the execution, delivery and performance of this Agreement have been duly authorized by such Member.

3.4 Restrictions on the Transfer of Interests.

(a) Permitted Transfers. Except for Transfers to Permitted Transferees or Transfers made in accordance with Section 3.1(f) or Section 3.6, no Member shall Transfer all or any portion of such Member’s Membership Interests, without the prior written Consent of the Managing Member, which consent may be given or withheld in the sole discretion of the Managing Member. Any purported Transfer in breach of the terms of this Agreement shall be null and void ab initio, and the Company shall not recognize any such prohibited Transfer on its books and records. Any Member who Transfers or attempts to Transfer any Membership Interests except in compliance herewith shall be liable to, and shall indemnify and hold harmless, the Company and the other Members for all costs, expenses, damages and other liabilities resulting therefrom. In connection with the Transfer of any Membership Interests, the holder of such Membership Interests shall deliver prior written notice to the Company describing in reasonable detail the proposed Transfer at least one Business Day prior thereto. For the avoidance of doubt, all Transfers to Permitted Transferees shall also comply with Sections 3.4(b) to 3.4(e). Notwithstanding anything to the contrary in this Agreement, no Transfer shall be permitted (i) to the extent such Transfer would, in the reasonable determination of the Managing Member, cause the Company to lose its status as a partnership for U.S. federal income tax purposes or, without limiting the generality of the foregoing, cause the Company to be treated as a “publicly traded partnership” or to be taxed as a corporation pursuant to Section 7704 of the Code and any applicable Treasury Regulations issued thereunder, or any successor provision of the Code, (ii) to the extent such Transfer would, in the reasonable determination of the Managing Member, result in the Company having more than one hundred (100) partners, within the meaning of Treasury Regulations Section 1.7704-1(h)(1) (determined pursuant to the rules of Treasury Regulations Section 1.7704-1(h)(3)), except as the Managing Member might reasonably determine that the Company can rely on one or more of the secondary market safe harbors set forth in Treasury Regulations Section 1.7704-1(c)(3), or (iii) unless (A) such Member already has a properly completed Internal Revenue Service Form W-9 on file with the Company, (B) such Member delivers to the Company an affidavit of non-foreign status with respect to such Member that satisfies the requirements of section 1446(f)(2) of the Code contemporaneously with or before the Transfer or (C) such Member causes the Transferee to properly withhold and remit to the Internal Revenue Service the amount of tax required to be withheld upon the Transfer by section 1446(f) of the Code and the Treasury Regulations promulgated thereunder (and no more than 10 days following the Transfer, provides evidence to the Company of such withholding and remittance). Any attempted Transfer that would cause the Company to be treated a publicly treated partnership or taxed as a corporation pursuant to Section 7704 of the Code shall be void ab initio and without effect.

15

(b) Securities Laws. Notwithstanding anything in this Agreement to the contrary, no Membership Interest shall be Transferred except pursuant to an effective registration statement under the Securities Act or an applicable exemption from registration and/or qualification under the Securities Act and any other applicable securities Laws.

(c) Effect of Permitted Transfer. Any Transfer of a Membership Interest that complies with Section 3.4(a) and Section 3.4(b) shall be effective to assign the right to become a Member, and, without the need for any action or Consent of any other Person, a Transferee of such Membership Interest shall automatically be admitted as a Member upon such Transferee’s delivery to the Managing Member of an executed customary joinder agreement prepared by the Company. As a condition to the Company’s obligation to effect a Transfer permitted hereunder, any Transferee of Membership Interests shall be required to (i) become a party to this Agreement as a Member and shall have the rights and obligations of a Member hereunder, (ii) expressly assume all liabilities and obligations of the Transferring Member (or its applicable Affiliates) to the Company or the other Members and (iii) if the Transferee is to be admitted to the Company as a new Member, acknowledge the representations and warranties in Section 3.3 are true and correct with respect to such Transferee as of the date such Person is to become a Member. Each Transfer is effective against the Company as of the first Business Day following delivery of the joinder agreement to the Company.

(d) Expenses. Except as provided in Section 3.4(a), the Company shall bear any ordinary course expenses it may incur in connection with effecting any Transfer of any Membership Interests. Any transfer or similar taxes arising as a result of the Transfer of a Member’s Membership Interest shall be paid by the Transferring Member. The Managing Member shall be reimbursed by the Company for any stock repurchase excise taxes incurred by the Managing Member in connection with any “repurchase” as defined in Section 4501(c)(1) of the Code.

(e) Distributions. Any distribution or payment made by the Company to the Transferring Member prior to such time as the Transferee was admitted as a Member pursuant to the provisions of this Agreement with respect to the Transfer of such Transferring Member’s Membership Interests shall constitute a release of the Company, the Managing Member, and the Members, of all liability to such Assignee or new Member who may be interested in such distribution or payment by reason of such Transfer.

16

3.5 Change in Business Form.

(a) If the Managing Member approves the reorganization of the Company or any of its Subsidiaries into another business form, each Member hereby consents to such reorganization or election and shall vote for (to the extent such Member has voting rights), raise no objections against such reorganization, and each Member shall take such actions as are reasonably requested by the Managing Member in connection with the consummation of such reorganization of the Company or any of its Subsidiaries as determined by the Managing Member. The method of effecting such reorganization shall be determined by the Managing Member.

(b) In connection with any such reorganization, (i) the organizational documents of the reorganized entity shall provide that the rights and obligations of the Members hereunder shall continue to apply substantially in accordance with the terms hereof, except to the extent the parties hereto otherwise agree in writing and (ii) each Membership Interest shall (effective upon and subject to the consummation of such reorganization) convert into equity securities of the reorganized entity and shall be allocated among the Members such that each Member shall receive equity securities in the reorganization entity with substantially similar economic rights as such Member’s former Membership Interests.

3.6 Exchange of Units.

(a) Legence Parent Exchange Rights. Subject to the terms and conditions of this Agreement and the Exchange Agreement, Legence Parent and its respective successors and assigns (the “Redeeming Member”) shall be entitled to exchange with the Company, at any time and from time to time upon delivery of a written notice (the “Redemption Notice”) to the Company, with a copy to LGN (the date of delivery of such Redemption Notice, the “Redemption Notice Date”), any or all of Legence Parent’s or its successors’ and assigns’ Class B Units (together with the same number of shares of Class B Stock) for an equivalent number of shares of Class A Stock or, at LGN’s option, subject and pursuant to the terms and conditions of the Exchange Agreement, cash (a “Cash Election” and, such amount, the “Cash Election Amount”) as set forth in the Exchange Agreement (each such transaction, a “Redemption”). Any such Redemption shall be treated for federal income tax purposes as a sale of the Redeeming Member’s Class B Units (together with the same number of shares of Class B Stock) to LGN in exchange for shares of Class A Stock or cash, as applicable.

(b) LGN Call Rights. Notwithstanding anything to the contrary in this Section 3.6, a Redeeming Member shall be deemed to have offered to sell its Class B Units as described in the Redemption Notice to LGN, and LGN may, in its sole discretion, by delivery of a notice in accordance with, and subject to the terms of, this Section 3.6(b) (a “Call Election Notice”), elect to purchase directly and acquire such Class B Units (together with the same number of shares of Class B Stock) on the Redemption Date by transferring to the Redeeming Member the number of shares of Class A Stock the Redeeming Member (or its designee) would otherwise receive pursuant to Section 3.6(a) and the Exchange Agreement or, at LGN’s election, an amount of cash equal to the Cash Election Amount of such shares of Class A Stock (the “Call Right”), whereupon LGN shall acquire the Class B Units offered for redemption by the Redeeming Member (together with the same number of shares of Class B Stock from Legence Parent). LGN shall be treated for all purposes of this Agreement as the owner of such Class B Units; provided, that if LGN funds the Cash Election Amount through the net proceeds of an issuance of equity securities of LGN other than shares of Class A Stock, such Class B Units will be reclassified into another equity security of the Company if the Managing Member determines such reclassification is necessary. LGN may, at any time prior to the Redemption Date, in its sole discretion, deliver a Call Election Notice to the Company and the Redeeming Member setting forth its election to

17

exercise its Call Right. A Call Election Notice may be revoked by LGN at any time; provided, that any such revocation does not prejudice the ability of the parties to consummate a Redemption on the Redemption Date. Except as otherwise provided by this Section 3.6(b), an exercise of the Call Right shall be consummated pursuant to the same timeframe and in the same manner as the relevant Redemption would have been consummated if LGN had not delivered a Call Election Notice.

ARTICLE IV

CAPITAL CONTRIBUTIONS

4.1 Capital Contributions; Return of Cash.

(a) General. Following the Effective Date, no Member shall be required to make any Capital Contributions to the Company, except as otherwise agreed to in writing by such Member, and any Capital Contributions following the Effective Date shall be made as detailed in, and subject to the provisions of Section 4.1(b).

(b) Capital Calls.

(i) To the extent approved by the Managing Member, from time to time, additional Capital Contributions may be called for from the Members if the Managing Member determines that such additional Capital Contributions are necessary for the conduct of the Company’s business (any such additional Capital Contributions called for from the Members by the Managing Member, being hereinafter referred to as an “Additional Call Amount”). In that event, the Members shall have the opportunity, but not the obligation, to participate in such additional Capital Contributions in accordance with their Percentage Interest. To the extent that some Members elect not to make an additional Capital Contribution, those Members that do elect to make an additional Capital Contribution shall have the opportunity, but not the obligation, to increase their additional Capital Contributions pro rata in accordance with their respective Percentage Interests such that the total of the additional Capital Contribution equals the Additional Call Amount.

(ii) Upon the funding of any Capital Contribution by a Member pursuant to clause (i) above, such Member shall be issued a number of additional Class A or Class B Units, as applicable, equal to the amount of the Capital Contribution made by such Member in respect of such Capital Contribution divided by the Fair Market Value of such Class A Units and Class B Units. Exhibit A and the books and records of the Company shall be thereafter amended accordingly.

(c) Excess Cash. Notwithstanding any other provision of this Agreement, if LGN acquires or holds any material amount of cash in excess of any monetary obligations it reasonably anticipates, LGN may, in its sole discretion:

(i) contribute (or cause to be contributed) such excess cash amount to the Company in exchange for a number of Class A Units, and distribute to holders of Class A Stock shares of Class A Stock; or

(ii) use such excess cash amount in such other manner, and make such other adjustments to or take such other actions with respect to the capitalization of LGN and the Company and to the one-to-one exchange ratio between Class A Units and Class A Stock, as LGN in good faith determines to be fair and reasonable to the shareholders and other equityholders of LGN and to the Members to preserve the intended economic effect of Section 3.1, Section 3.6 and the other provisions hereof.

4.2 Capital Accounts. The Company shall maintain for each Member a separate Capital Account in accordance with the rules of Treasury Regulation section 1.704-1(b)(2)(iv) and in accordance with the following provisions:

(a) Each Member’s Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Company by such Member pursuant to this Agreement (net of any liabilities assumed by the Company in connection with such Capital Contributions and any

18

liabilities to which any property comprising such Capital Contributions is subject), and (ii) all Profits and any other items of Company income and gain allocated with respect to such Member pursuant to Section 5.1, and decreased by (x) the amount of cash or Agreed Value of property actually or deemed distributed to such Member pursuant to this Agreement (net of liabilities assumed by such Member and the liabilities to which such property is subject), and (y) all Losses and any other items of Company deduction and loss allocated to such Member pursuant to Section 5.1.

(b) The amount of any profits or losses of the Company that are to be allocated pursuant to Article V and reflected in the Members’ Capital Accounts (“Profits” or “Losses”) shall equal the Company’s taxable income or loss for the applicable period determined in accordance with section 703(a) of the Code (for this purpose, all items of income, gain, loss, or deduction required to be stated separately pursuant to section 703(a)(1) of the Code shall be included in taxable income or loss, as applicable), and otherwise in accordance with the methods of accounting followed by the Company for federal income tax purposes.

(c) Notwithstanding the foregoing (without duplication):

(i) Any income of the Company that is exempt from federal income tax and not otherwise taken into account in computing Profits and Losses pursuant to the definition of “Profits” and “Losses” shall be added to such taxable income or loss.

(ii) Any expenditures of the Company described in section 705(a)(1)(B) or 705(a)(2)(B) of the Code or treated as section 705(a)(2)(B) of the Code expenditures pursuant to Treasury Regulation section 1.704-1(b)(2)(iv)(i) and not currently deductible nor capitalized for federal income tax purposes shall be subtracted from such taxable income or loss.

(iii) To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(iv) In lieu of the depreciation, amortization and other cost recovery deductions taken into account in computing such items, there shall be taken into account Depreciation, computed in accordance with the definition of “Depreciation.”

(v) For purposes of determining income, gain, loss, and deduction, or any other item allocable to any period, such items will be determined on a daily, monthly or other basis, as reasonably determined by the Partnership Representative using any permissible method under section 706 of the Code and the related Treasury Regulations.

19

(vi) If the Carrying Value of any asset differs from its adjusted tax basis for U.S. federal income tax purposes, any gain or loss resulting from a disposition of such asset shall be calculated with reference to such Carrying Value.

(vii) In the event an adjustment to the Carrying Value of the assets of the Company occurs pursuant to Section 4.2(e), any Unrealized Gain or Unrealized loss shall be treated as having been actually realized.

(viii) Any items that are allocated pursuant to Section 5.1(c) shall not be taken into account in computing Profits and Losses, but such items available to be specially allocated will be determined by applying rules analogous to those set forth in clauses (i) through (vii) above.

(d) A Transferee shall succeed to the pro rata portion of the Capital Account of the transferor relating to the Membership Interest so Transferred. Except as otherwise provided herein, all items of income, gain, expense, loss, deduction, and credit allocable to any Membership Interest that may have been Transferred during any calendar year shall, if permitted by law, be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as owning that Membership Interest, based upon the interim closing of the books method or such other method as agreed between the transferor, the transferee and the Company; provided however, that this allocation must be made in accordance with a method permissible under section 706 of the Code and the Treasury Regulations thereunder.

(e) In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), (i) on an issuance of additional Membership Interests for more than a de minimis amount of cash or Contributed Property; (ii) immediately prior to any actual or deemed distribution to a Member of more than a de minimis amount of Company property in redemption or retirement of a Membership Interest; (iii) on the date of the liquidation or dissolution of the Company within the meaning of Treasury Regulation section 1.704-1(b)(2)(ii)(g); (iv) on the grant of a Membership Interest (other than a de minimis Membership Interest) as consideration for the provision of services to or for the benefit of the Company by an existing Member acting in a member capacity, or by a new Member acting in a member capacity or in anticipation of becoming a Member of the Company; (v) upon the acquisition of a Membership Interest in the Company by any new or existing Member upon the exercise of a noncompensatory option in accordance with Treasury Regulations section 1.704-1(b)(2)(iv)(s); or (vi) at such other times as the Partnership Representative shall reasonably determine to be necessary or advisable in order to comply with Treasury Regulations section 1.704-1(b), the Capital Accounts of all Members and the Carrying Value of each Company property immediately prior to such issuance or adjustment (or immediately after in the case of an acquisition described in clause (v)) shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property and had been allocated to the Members at such time pursuant to Section 5.1 in the same manner as any item of gain or loss actually recognized during such period would have been allocated. Notwithstanding the foregoing, such adjustments pursuant to clauses (i), (ii), (iv) and (v) above shall be made only if the Partnership Representative determines that such adjustments are necessary or appropriate to reflect the relative economic interests of the Members in the Company without material distortion (materiality to be determined in the sole discretion of the Partnership Representative). In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and Fair Market Value of all Company assets (including cash equivalents) immediately prior to the event

20

triggering such adjustment shall be determined by the Partnership Representative using such method of valuation as it may reasonably adopt. The Partnership Representative shall allocate such aggregate value among the assets of the Company (in such manner as it determines) to arrive at a Fair Market Value for individual properties. If any noncompensatory options or warrants are outstanding upon the occurrence of an event described in clauses (i) through (vi) above, the Company shall adjust the Carrying Value of its properties in accordance with Treasury Regulation sections 1.704-1(b)(2)(iv)(f)(1) and 1.704-1(b)(2)(iv)(h)(2). The Carrying Value of Company assets shall be increased (or decreased) to reflect any adjustments to the adjusted basis of such assets pursuant to section 734(b) or section 743(b) of the Code, but only to the extent that such adjustments are taken into account in determining Capital Accounts pursuant to Treasury Regulation section 1.704-1(b)(2)(iv)(m). Notwithstanding the foregoing, the Carrying Values shall not be adjusted pursuant to the immediately preceding sentence to the extent that an adjustment pursuant to clauses (i) through (v) above is made in connection with a transaction that would otherwise result in an adjustment pursuant to the immediately preceding sentence. If the Carrying Value of a Company asset has been determined or adjusted pursuant to this Section 4.2(e) (other than with respect to the Carrying Value of a Company asset being distributed to a Member), such Carrying Value shall thereafter be adjusted by the Depreciation taken into account with respect to such Company asset.

4.3 Contributions of Contributed Property. Except as set forth within the Master Reorganization Agreement, all Capital Contributions currently contemplated by this Agreement are to be made in readily available cash funds. To the extent that, as determined by the Managing Member, any subsequent Capital Contribution is made in the form of Contributed Property, any costs or expenses associated with the transfer, assignment, conveyance or recordation of such Contributed Property, including any taxes in respect thereof, shall be borne by the Member making such contribution, and any such costs or expenses, whether paid directly by the Member or reimbursed to the Company, shall not be deemed Capital Contributions.

ARTICLE V

ALLOCATIONS AND DISTRIBUTIONS

5.1 Allocations for Capital Account Purposes.

(a) General. Except as otherwise provided in this Agreement, Profits and Losses for a taxable year (or portion thereof) shall be allocated among the Members in a manner such that, after giving effect to the special allocations set forth in Section 5.1(b), the Capital Account of each Member, immediately after making such allocation, is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made to such Member pursuant to Section 10.2(d) if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Carrying Value, all Company liabilities were satisfied (limited with respect to each nonrecourse liability to the Carrying Value of the assets securing such liability), and the net assets of the Company were distributed in accordance with Section 10.2(d)(ii) to the Members immediately after making such allocation, minus (ii) such Member’s share of Company Minimum Gain and Member Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets, and the amount such Member is treated as obligated to contribute to the Company, computed immediately after the hypothetical sale of assets. Notwithstanding the foregoing, the allocations pursuant to this Section 5.1(a) may be adjusted (including by allocating items of income, gain, loss and

21

expense includable in the computation of Profits and Losses) to the extent the Partnership Representative determines that such adjustment is necessary to comply with the provisions of Section 704(b) of the Code and the Treasury Regulations under Section 704(b) of the Code or give economic effect to Section 5.3 and 10.2 and the other relevant provisions of this Agreement.

(b) Special Allocations. Notwithstanding any other provision of this Section 5.1, the following special allocations shall be made for such taxable period in the following order and priority:

(i) Company Minimum Gain Chargeback. Notwithstanding the other provisions of this Section 5.1, if there is a net decrease in Company Minimum Gain during any Fiscal Year, each Member shall be allocated items of Company income and gain for such taxable period (and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections 1.704-2(f)(6) and (g)(2) and section 1.704-2(j)(2)(i), or any successor provisions. This Section 5.1(b)(i) is intended to comply with the Company Minimum Gain chargeback requirement in Treasury Regulation section 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt. Notwithstanding the other provisions of this Section 5.1 (other than Section 5.1(b)(i)), except as provided in Treasury Regulation section 1.704-2(i)(4), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Fiscal Year, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such Fiscal Year shall be allocated items of Company income and gain for such Fiscal Year (and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. This Section 5.1(b)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation sections 1.704-1(b)(2)(ii)(d)(4), (5) and (6), items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under section 704(b) of the Code, the deficit balance, if any, in such Member’s Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Section 5.1(b)(iii) shall be made only if and to the extent that such Member would have a deficit in such Member’s Adjusted Capital Account after all other allocations provided in this Article V have been tentatively made as if this Section 5.1(b)(iii) were not a part of this Agreement. This Section 5.1(b)(iii) is intended to be a “qualified income offset” as that term is used in Treasury Regulation section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

22

(iv) Stop Loss. No amount of loss or deduction shall be allocated pursuant to Section 5.1(a) or Section 5.1(c) to the extent that such allocation would cause any Member to have a deficit balance in its Adjusted Capital Account at the end of such Fiscal Year (or increase any existing deficit balance in its Adjusted Capital Account) while any other Member has an Adjusted Capital Account with positive balance. All loss and deductions in excess of the limitation set forth in the preceding sentence shall be allocated among such other Members, who have positive Adjusted Capital Account balances, in proportion thereto until each Member’s Adjusted Capital Account balance is reduced to zero.

(v) Gross Income Allocations. In the event any Member has a deficit balance in its Capital Account at the end of any Company taxable period, such Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 5.1(b)(v) shall be made only if and to the extent that such Member would have a deficit balance in its Capital Account after all other allocations provided in this Section 5.1 have been tentatively made as if this Section 5.1(b)(v) and Section 5.1(b)(iii) were not in the Agreement.

(vi) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Members in any manner determined by the Partnership Representative and permissible under the Treasury Regulations.

(vii) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any Fiscal Year shall be allocated one hundred percent (100%) to the Member that bears the Economic Risk of Loss with respect to such Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation section 1.704-2(i). If more than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, such Member Nonrecourse Deductions attributable to a Member Nonrecourse Debt shall be allocated between or among such Members in accordance with the ratios in which they share such Economic Risk of Loss.

(viii) Nonrecourse Liabilities. Any “excess nonrecourse liabilities” of the Company, within the meaning of Treasury Regulation section 1.752-3(a)(3), shall be allocated to the Members in any manner determined by the Partnership Representative and permissible under the Treasury Regulations.

(ix) Partnership Tax Audit Adjustments. Items of income, gain, loss, expense or credit resulting from a Covered Audit Adjustment shall be allocated to the Members in accordance with the applicable provisions of the Partnership Tax Audit Rules.

(x) Curative Allocation. Notwithstanding any other provision of this Section 5.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss or deduction allocated to each Member pursuant to the Required Allocations and the Agreed Allocations, together,

23

shall be equal to the net amount of such items that would have been allocated to each such Member under the Agreed Allocations had the Required Allocations and the related Curative Allocations not otherwise been provided in this Section 5.1. It is the intention of the Members that allocations pursuant to this Section 5.1(b)(x) be made among the Members in a manner that is likely to minimize economic distortions.

(c) Allocations on Liquidation. Notwithstanding any other provisions of this Article V, after taking into account the special allocations in Section 5.1(b), in the year in which the Company liquidates pursuant to Article X and all subsequent years (and for any prior years with respect to which the due date (without regard to extensions) for the filing of the Company’s federal income tax return has not passed as of the date of the liquidation), all items of income, gain, loss and deduction of the Company shall be allocated among the Members in a manner reasonably determined by the Partnership Representative as shall cause to the nearest extent possible the Capital Account of each Member to equal the amount to be distributed to such Member pursuant to Section 10.2(d)(ii).

5.2 Allocations for Tax Purposes.

(a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Members in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 5.1.

(b) Notwithstanding any provisions contained herein to the contrary, solely for federal (and applicable state and local) income tax purposes, items of income, gain, depreciation, amortization, gain or loss with respect to property for which a Book-Tax Disparity exists, shall be allocated so as to take into account the variation between the Company’s tax basis in such property and its Carrying Value consistent with Treasury Regulations sections 1.704-1(b)(4)(i) and 1.704-3. Such allocations shall be made in accordance with such methods provided for in Treasury Regulations section 1.704-3 as reasonably determined by the Partnership Representative.

(c) For the proper administration of the Company, the Partnership Representative shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations for federal income tax purposes of income (including gross income or deductions); and (iii) amend the provisions of this Agreement as appropriate to reflect the proposal or promulgation of Treasury Regulations under section 704(b) or section 704(c) of the Code. The Partnership Representative may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 5.2(c) only if such conventions, allocations or amendments are consistent with the principles of section 704 of the Code and would not have a material adverse effect on any Member.

(d) All recapture of income tax deductions resulting from the taxable sale or other disposition of Company property shall, to the maximum extent possible, be allocated to the Member to whom the deduction that gave rise to such recapture was allocated hereunder to the extent that such Member is allocated any gain from the disposition of such property.

24

(e) All items of income, gain, loss, deduction and credit recognized by the Company for federal income tax purposes and allocated to the Members in accordance with the provisions hereof shall be determined without regard to the election under section 754 of the Code that will be made by the Company; provided however, that such allocations, once made, shall be adjusted (in any manner determined by the Partnership Representative) as necessary or appropriate to take into account those adjustments permitted or required by sections 734 and 743 of the Code.

(f) If, as a result of an exercise of a noncompensatory option to acquire a Membership Interest in the Company, a Capital Account reallocation is required under Treasury Regulations section 1.704-1(b)(2)(iv)(s)(3), the Company shall make corrective allocations pursuant to Treasury Regulations section 1.704-1(b)(4)(x).

5.3 Requirement of Distributions.

(a) Subject to the provisions of Section 5.3(b) and Section 10.2(d), distributions of assets and properties of the Company shall be made by the Company at such times as determined by the Managing Member in its sole discretion. Each distribution of cash or other property by the Company shall be made 100% to the Members pro rata in accordance with each Member’s Percentage Interest. Distributions of cash shall be made to the Members by wire transfer or ACH to the account designated by the relevant Member. For purposes of the foregoing, if payments are made by or on behalf of the Company to a Member or an Affiliate thereof other than in respect of such Member’s Membership Interests (including in respect of indebtedness for borrowed money), then such payments shall not be considered a distribution for purposes of determining the allocation of a distribution pursuant to this Section 5.3(a).

(b) Notwithstanding the foregoing, the Managing Member shall cause Available Cash to be distributed at least five days prior to each of April 15, June 15, September 15 and December 15 (or any other successor or substitute estimated tax payment date applicable to corporate taxpayers) (each an “Estimated Tax Payment Date”), with respect to the taxable period related to each Estimated Tax Payment Date (each, an “Estimated Tax Period”), to each Member. Such distributions shall be made pro rata to each Member based on such Member’s pro rata share of the Tax Amount (taking into account such Member’s Percentage Interest as of the date of such applicable distribution pursuant to this Section 5.3(b)); provided, that, a Member’s pro rata share of the Tax Amount will only be distributed to such Member to the extent that the aggregate amount previously distributed to such Member pursuant to Section 5.3(a) hereof or this Section 5.3(b) in such Fiscal Year is less than the amount required to be distributed to such Member on such Estimated Tax Payment Date under this Section 5.3(b); provided, further, that there will be an adjustment following each Fiscal Year (but no later than one day prior to the due date for payment of U.S. federal taxes by a corporation), and the Company shall distribute any additional amounts as necessary to make the amounts previously distributed to a Member pursuant to Section 5.3(a) hereof or this Section 5.3(b) in such Fiscal Year equal such Member’s pro rata share of the Tax Amount (taking into account such Member’s Percentage Interest) attributable to such Fiscal Year. The “Tax Amount” calculated for the period beginning on the start of the Fiscal Year through the end of the applicable Estimated Tax Period is the Class A Member Tax Amount divided by the Percentage Interest attributable to the Class A Member as of the date of such applicable distribution pursuant to this Section 5.3(b). The “Class A Member Tax Amount” is the sum of (x)(i) the U.S. federal, state and local estimated aggregate taxable income of the Company allocated to the Class

25

A Member for such Estimated Tax Period or such Fiscal Year (for the avoidance of doubt, including any adjustments under section 734 or 743 of the Code and any allocations of taxable income under section 704(c) of the Code), multiplied by (ii) the U.S. federal, state and local estimated effective tax rate of the Class A Member for such Fiscal Year and (y) such additional amounts the Managing Member reasonably determines in good faith is necessary to enable LGN to timely meet its payment obligations under the Tax Receivable Agreement.

5.4 Withholding. To the extent the Company (or any entity in which the Company owns a direct or indirect interest) is required by law to withhold or to make tax payments on behalf of or with respect to any Member (“Tax Advances”), the Company may withhold such amounts and make such tax payments as so required. All Tax Advances made on behalf of a Member shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Member. If (a) at the time a Member ceases to be a Member, (b) at the time of liquidation of the Company or (c) at any other time determined by the Board, any such Tax Advances to a Member are or would remain outstanding, such Member shall repay such amount to the Company. If a distribution to a Member is actually reduced as a result of a Tax Advance, for all purposes of this Agreement such Member shall be treated as having received a distribution equal to the amount of such Tax Advance. Each Member hereby agrees to indemnify and hold harmless the Company and the other Members from and against any liability from such Member’s failure to repay Tax Advances (including for the avoidance of doubt any penalty or interest incurred with respect to such withholding). Each Member shall provide the Company with such information that the Company reasonably requests in order to determine the amount of any taxes required to be withheld with respect to such Member. For the avoidance of doubt, any taxes, penalties and interest payable under the Partnership Tax Audit Rules by the Company or any fiscally transparent entity in which the Company owns an interest shall be treated as Tax Advances specifically attributable to the Members and the Partnership Representative shall use commercially reasonable efforts to allocate the burden of (or any diminution in distributable proceeds resulting from) any such taxes, penalties or interest to the Members to whom such amounts are specifically attributable (whether as a result of their status, actions, inactions or otherwise) as determined by the Partnership Representative. Notwithstanding any other provision of this Agreement, (i) any Person who ceases to be a Member shall be treated as a Member for purposes of this Section 5.4, (ii) the obligations of a Member pursuant to this Section 5.4 shall survive indefinitely with respect to any taxes (and any related penalties and interest) withheld or paid by the Company that relate to the period during which such Person was actually a Member, regardless of whether such taxes are assessed, withheld or otherwise paid during such period and (iii) a Member’s obligation to indemnify the Company and the other Members and make contributions to the Company under this Section 5.4 shall survive the termination, dissolution, liquidation, cancellation, and winding up of the Company, and for purposes of this Section 5.4 to the fullest extent permitted by applicable Law, the Company shall be treated as continuing in existence. The Company may pursue and enforce all rights and remedies it may have against each Member under this Section 5.4, including instituting a lawsuit to collect such amounts required to be paid to the Company or otherwise borne by the Company, with interest calculated at a rate equal to 10.0% per annum (but not in excess of the highest rate per annum permitted by applicable Law), compounded on the last day of each fiscal quarter.

ARTICLE VII

INDEMNIFICATION

7.1 Right to Indemnification. Subject to the limitations and conditions as provided herein and to the fullest extent permitted by applicable Laws, each Person who was or is made a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (hereinafter a “Proceeding”), or any appeal in such a Proceeding or any inquiry or investigation that could lead to such a Proceeding, by reason of the fact that he or she, or a Person of whom he or she is the legal representative, is or was a Member of the Company or Affiliate thereof or any of their respective representatives, an officer or employee of the Company or Affiliate or a director, officer, member or employee of the Managing Member or any Affiliate, a member of a committee of the Company or an officer of the Company, or while such a Person is or was serving at the request of the Managing Member on behalf of the Company as a manager, director, officer, partner, venturer, member, trustee, Partnership Representative or Designated Individual, employee, agent or similar functionary of another foreign or domestic general partnership, corporation, limited partnership, joint venture, limited liability company, trust, employee benefit plan or other enterprise (each an “Indemnitee”), shall be indemnified by the Company to the extent such Proceeding or other above-described process relates to any such above-described relationships with, status with respect to, or representation of any such Person to the fullest extent permitted by the Act, as the same exists or may hereinafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said Laws permitted the Company to provide prior to such amendment), against judgments, penalties (including excise and similar taxes and punitive damages), fines, settlements and reasonable expenses (including attorneys’ and experts’ fees) actually incurred by such Person in connection with such Proceeding, and indemnification under this Article VII shall continue as to a Person who has ceased to serve in the capacity which initially entitled such Person to indemnity hereunder for any and all liabilities and damages related to and arising from such Person’s activities while acting in such capacity; provided however, that no Person shall be entitled to indemnification under this Section 7.1 if there has been a final and non-appealable judgment

30

entered by a court of competent jurisdiction determining that, in respect of the matter for which such Person is seeking indemnification pursuant to this Section 7.1 such Person’s actions or omissions constituted an intentional breach of this Agreement or gross negligence or willful misconduct on the part of such Person or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Article VII 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 loan any monies or property to the Company to enable it to effectuate such indemnification. The rights granted pursuant to this Article VII shall be deemed contract rights, and no amendment, modification or repeal of this Article VII shall have the effect of limiting or denying any such rights with respect to actions taken or Proceedings arising prior to any such amendment, modification or repeal. An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.1 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. IT IS ACKNOWLEDGED THAT THE INDEMNIFICATION PROVIDED IN THIS SECTION 7.1 COULD INVOLVE INDEMNIFICATION FOR NEGLIGENCE OR UNDER THEORIES OF STRICT LIABILITY.

7.2 Indemnification of Officers, Employees (if any) and Agents. The Company may indemnify and advance expenses to Persons who are not entitled to indemnification under Section 7.1, including current and former employees (if any) or agents of the Company, and those Persons who are or were serving at the request of the Company as a manager, director, officer, partner, venturer, member, trustee, employee (if any), agent or similar functionary of another foreign or domestic general partnership, corporation, limited partnership, joint venture, limited liability company, trust, employee benefit plan or other enterprise against any liability asserted against such Person and incurred by such Person in such a capacity or arising out of his status as such a Person to the same extent that it may indemnify and advance expenses to a Member under this Article VII.

7.3 Indemnification and Expense Advancement With Respect to Actions Commenced by an Indemnitee. Notwithstanding 7.1, Section 7.2 and Section 7.4, the Company shall be required to indemnify and advance expenses to an Indemnitee in connection with any action, suit or proceeding commenced by such Indemnitee only if the commencement of such action, suit or proceeding by such Indemnitee was authorized by the Managing Member in its sole discretion.

7.4 Advance Payment. Any right to indemnification conferred in this Article VII shall include a limited right to be paid or reimbursed by the Company for any and all reasonable expenses as they are incurred by a Person entitled or authorized to be indemnified under Sections 7.1 and 7.2 who was, is or is threatened, to be made a named defendant or respondent in a Proceeding in advance of the final disposition of the Proceeding and without any determination as to such Person’s ultimate entitlement to indemnification; provided however, that the payment of such expenses incurred by any such Person in advance of final disposition of a Proceeding shall be made only upon delivery to the Company of a written affirmation by such Person of his good faith belief that he has met the requirements necessary for indemnification under this Article VII and a written undertaking by or on behalf of such Person to repay all amounts so advanced if it shall ultimately be determined that such indemnified Person is not entitled to be indemnified under this Article VII or otherwise.

31

7.5 Appearance as a Witness. Notwithstanding any other provision of this Article VII, the Company shall pay or reimburse expenses incurred by any Person entitled to be indemnified pursuant to this Article VII in connection with such Person’s appearance as a witness or other participation in a Proceeding at a time when he is not a named defendant or respondent in the Proceeding.

7.6 Nonexclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in this Article VII shall not be exclusive of any other right which a Person indemnified pursuant to Sections 7.1 and 7.2 may have or hereafter acquire under any Laws, this Agreement, or any other agreement, vote of Members or otherwise. The Company may purchase and maintain (or may reimburse an Indemnitee for the cost of) insurance, on behalf of an Indemnitee as the Managing Member shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Indemnitee in connection with the Company’s activities or such Indemnitee’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Indemnitee against such liability under the provisions of this Agreement.

7.7 No Member Liability for Indemnification Obligations. In no event may an Indemnitee subject the Members to personal liability by reason of the indemnification provisions set forth in this Agreement. An Indemnitee shall not be denied indemnification in whole or in part under this Article VII 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.

7.8 Member Notification. To the extent discretionary to the Company, the Managing Member shall approve or disapprove of indemnification or advancement of expenses under this Article VII. Any indemnification of or advance of expenses to any Person entitled or authorized to be indemnified under this Article VII shall be reported in writing to the Managing Member within the 12 month period immediately following the date the indemnification or advance was made; provided, that no failure to comply with the notification provisions of this Section 7.8 shall operate to deprive a Person of any indemnification or advancement of expenses to which such Person would otherwise be entitled.

7.9 Savings Clause. If this Article VII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify and hold harmless any Person entitled to be indemnified pursuant to this Article VII as to costs, charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Article VII that shall not have been invalidated and to the fullest extent permitted by Laws.

7.10 Scope of Indemnity. For the purposes of this Article VII, references to the “Company” include all constituent entities, whether corporations or otherwise, absorbed in a consolidation or merger as well as the resulting or surviving entity. Thus, any Person entitled to be indemnified or receive advances under this Article VII shall stand in the same position under the provisions of this Article VII with respect to the resulting or surviving entity as he would have if such merger, consolidation, or other reorganization never occurred.

32

7.11 Other Indemnities.

(a) The Company acknowledges and agrees that the obligation of the Company under this Agreement to indemnify or advance expenses to any Indemnitee for the matters covered thereby shall be the primary source of indemnification and advancement of such Indemnitee in connection therewith and any obligation on the part of any Indemnitee under any Other Indemnification Agreement to indemnify or advance expenses to such Indemnitee shall be secondary to the Company’s obligation and shall be reduced by any amount that the Indemnitee may collect as indemnification or advancement from the Company. If the Company fails to indemnify or advance expenses to an Indemnitee as required or contemplated by this Agreement, and any Person makes any payment to such Indemnitee in respect of indemnification or advancement of expenses under any Other Indemnification Agreement on account of such Unpaid Indemnity Amounts, such other Person shall be subrogated to the rights of such Indemnitee under this Agreement in respect of such Unpaid Indemnity Amounts.

(b) The Company, as an indemnifying Party from time to time, agrees that, to the fullest extent permitted by applicable Law, its obligation to indemnify Indemnitees under this Agreement shall include any amounts expended by any other Person under any Other Indemnification Agreement in respect of indemnification or advancement of expenses to any Indemnitee in connection with any Proceedings to the extent such amounts expended by such other Person are on account of any Unpaid Indemnity Amounts.

7.12 Replacement of Fiduciary Duties. Notwithstanding any other provision of this Agreement, to the extent that any provision of this Agreement purports or is interpreted (a) 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 the Managing Member or any other Indemnitee to the Company, the Members, any other Person who acquires an interest in a Membership Interest or any other Person who is bound by this Agreement or (b) to constitute a waiver or consent by the Company, the Members, any other Person who acquires an interest in a Membership Interest or any other Person who is bound by this Agreement to any such replacement or restriction, such provision shall be deemed to have been approved by the Company, all of the Members, each other Person who acquires an interest in a Membership Interest and each other Person who is bound by this Agreement.

7.13 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, any other Person who acquires an interest in a Membership Interest or any other Person who is bound by this Agreement, 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 in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal. The Members, any other Person who acquires an interest in a

33

Membership Interest or any other Person who is bound by this Agreement, each on their own behalf and on behalf of the Company, waives any and all rights to claim punitive damages or damages based upon the federal or state income taxes paid or payable by any such Member or other Person.

(b) The Managing Member may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agent or agents, and the Managing Member shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the Managing Member in good faith.

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Company, the Members, any Person who acquires an interest in a Membership Interest or any other Person who is bound by this Agreement, any Indemnitee acting in connection with the Company’s business or affairs shall not be liable, to the fullest extent permitted by Law, to the Company, to any Member, to any other Person who acquires an interest in a Membership Interest or to any other Person who is bound by this Agreement for its reliance on the provisions of this Agreement.

(d) Any amendment, modification or repeal of this Agreement 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 Agreement 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.

(a) approval of dissolution by (x) the Managing Member and (y) the Members holding at least 66 ²⁄₃% of the issued and outstanding Class B Units;

(b) the consummation of a sale of all or substantially all of the assets of the Company; or

(c) entry of a decree of judicial dissolution of the Company in accordance with the Act.

37

Dissolution of the Company shall be effective on the day on which the event occurs giving rise to the dissolution, but the Company will not terminate until the assets of the Company have been liquidated and the assets distributed as provided in Section 10.2 and the Certificate has been canceled.

10.2 Liquidation and Termination. In connection with the winding up and dissolution of the Company, the Managing Member shall act as a liquidator (“Liquidator”), unless the Managing Member otherwise determines. The Liquidator shall proceed diligently to wind up the affairs of the Company in an orderly manner and make final distributions as provided herein and in the Act. The Liquidator shall use commercially reasonable efforts to complete the liquidation of the Company within two years after an applicable Dissolution Event; provided, that such period may be extended for up to two additional one-year periods by the Managing Member. The costs of liquidation shall be borne as a Company expense (including the costs and expenses of the Liquidator, in its capacity as such). Until final distribution, the Liquidator shall continue to operate the Company properties for a reasonable period of time to allow for the sale of all or a part of the assets thereof with all of the power and authority of the Members. The steps to be accomplished by the Liquidator are as follows:

(a) as promptly as possible after approval of the winding up and dissolution of the Company and again after final liquidation, the Liquidator shall cause a proper accounting to be made of the Company’s assets, liabilities, and operations through the last day of the calendar month in which the winding up and dissolution is approved or the final liquidation is completed, as applicable;

(b) the Liquidator shall cause any notices required by applicable Law to be sent to each known creditor of and claimant against the Company in the manner described by applicable Law;

(c) upon approval of the winding up and dissolution of the Company, the Liquidator shall, unless the Managing Member otherwise determines, be prohibited from distributing assets in kind and shall instead sell for cash the equity of the Company or the assets of the Company at the best price available. The property of the Company shall be liquidated as promptly as is consistent with obtaining the fair value thereof. The Liquidator may sell all of the Company property, including to one or more of the Members. If any assets are sold or otherwise liquidated for value, the Liquidator shall proceed as promptly as practicable in a commercially reasonable manner to implement the procedures of this Section 10.2(c); and

(d) subject to the terms and conditions of this Agreement and any applicable Law (including the Act), the Liquidator shall distribute the assets of the Company in the following order of priority:

(i) First, the Liquidator shall pay, satisfy or discharge from Company assets all of the debts, liabilities and obligations of the Company, or otherwise make adequate provision for payment, satisfaction and discharge thereof; provided however, that such payments shall not include any Capital Contributions described in Article IV or any other obligations of the Members created by this Agreement; and

38

(ii) Second, all remaining assets of the Company shall be distributed to the Members in accordance with Section 5.3.

(e) All distributions to the Members pursuant to Section 10.2(d)(ii) above shall be in the form of cash, unless the Managing Member otherwise determines (and is further approved by the Members holding at least 66 ²⁄₃% of the issued and outstanding Class B Units pursuant to Section 6.2(b)).

(f) When the Liquidator has complied with the foregoing liquidation plan, the Liquidator (or the Managing Member), on behalf of all Members, shall execute, acknowledge and cause to be filed a Certificate of Cancellation.

10.3 Provision for Contingent Claims.

(a) The Liquidator shall make a reasonable provision to pay all claims and obligations, including all contingent, conditional or unmatured claims and obligations, actually known to the Company but for which the identity of the claimant is unknown; and

(b) If there are insufficient assets to both pay the creditors pursuant to Section 10.2 and to establish the provision contemplated by Section 10.3(a), subject to applicable Law, the claims shall be paid as provided for in accordance to their priority, and, among claims of equal priority, ratably to the extent of assets therefor.

10.4 Deficit Capital Accounts. No Member shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Company.

10.5 Deemed Contribution and Distribution. In the event the Company is “liquidated” within the meaning of Treasury Regulation section 1.704-1(b)(2)(ii)(g) but no Dissolution Event has occurred, the Company’s property shall not be liquidated, the Company’s liabilities shall not be paid or discharged, and the Company’s affairs shall not be wound up. Instead, solely for federal income tax purposes, the Company shall be deemed to have contributed all Company property and liabilities to a new limited liability company in exchange for an interest in such new limited liability company and, immediately thereafter, the Company will be deemed to liquidate by distributing interests in the new limited liability company to the Members.
