ARTICLE 6

DISTRIBUTIONS

Section 6.01. Distributions. To the extent permitted by Applicable Law and hereunder, distributions to Members may be declared by the Managing Member out of funds legally available therefor in such amounts and on such terms (including the payment dates of such distributions) as the Managing Member shall determine using such record date as the Managing Member may designate; such distribution shall be made to the Members as of the close of business on such record date on a pro rata basis in accordance with each Member’s Percentage Interest as of the close of business on such record date; provided, however, that the Managing Member shall have the obligation to make distributions as set forth in Sections 6.02 and 11.01; and provided further that, notwithstanding any other provision herein to the contrary, no distributions shall be made to any Member to the extent such distribution would render the Company insolvent. For purposes of the foregoing sentence, insolvency means the inability of the Company to meet its payment obligations when due. Promptly following the designation of a record date and the declaration of a distribution pursuant to this Section 6.01, the Managing

Member shall give notice to each Member of the record date, the amount and the terms of the distribution and the payment date thereof. In furtherance of the foregoing, it is intended that the Managing Member shall, to the extent permitted by Applicable Law and hereunder, have the right in its sole discretion to make distributions to the Members pursuant to this Section 6.01 in such amounts as shall enable WIND to meet its obligations pursuant to the Tax Receivable Agreement.

Section 6.02. Distributions for Payment of Income Tax. On or about each date (a “Tax Distribution Date”) that is five (5) Business Days prior to the date on which estimated U.S. federal income tax payments are required to be made by calendar year individual taxpayers and each due date for the U.S. federal income tax return of an individual calendar year taxpayer (without regard to extensions), the Company shall make a distribution to each Member of cash in an amount equal to such Member’s Assumed Tax Liability, if any (the “Tax Distributions”) Distributions pursuant to this Section 6.02 shall be treated as an advance distribution under Section 6.01 and shall be offset against future distributions that such holder of Membership Interests would otherwise be entitled to receive pursuant to Section 6.01. The calculation of Assumed Tax Liability shall take into account the carry forward of prior losses and the character of the items allocated (e.g., capital or ordinary) and shall treat each distribution made pursuant to this Section 6.02 as a payment of taxes or estimated taxes. If on a Tax Distribution Date there are not sufficient funds on hand to distribute to each Member the full amount of such Member’s Assumed Tax Liability, distributions pursuant to this Section 6.02 shall be made to the Members to the extent of the available funds in proportion to each Member’s Assumed Tax Liability and the Company shall make future distributions as soon as funds become available to pay the remaining portion of such Member’s Assumed Tax Liability. To the extent that, on any Tax Distribution Date, a Member would otherwise be entitled to receive less than its Percentage Interest of the aggregate Tax Distributions to be paid on such date, the Tax Distributions to such Member shall be increased to ensure that all distributions made pursuant to this Section 6.02 shall be made on a pro rata basis in accordance with Percentage Interests. In the event of any audit adjustment by a taxing authority that affects the calculation of any Member’s Tax Distribution for any taxable tear, or in the event the Company files an amended return which has such effect, each Member’s Tax Distribution with respect to such year shall be recalculated by giving effect to such audit adjustment or changes reflected in the amended return, as applicable (and by including therein an additional amount that, when distributed to the Members pursuant to this sentence, will be sufficient to cover any interest or penalties incurred by any of Member or former Member in connection therewith), and (x) any shortfall in the amount of Tax Distributions the Members and Former Members received for the relevant taxable years based on such audit recalculated Tax Distribution amount shall promptly be distributed to such Members and Former Members, except to the extent that distributions were made to such Members and former Members pursuant to Section 6.01 in the relevant taxable years and (y) any excess in the amount of Tax Distributions the Members received for the relevant taxable years based audit recalculated Tax Distribution shall be applied against the subsequent Tax Distributions due to such Member.

Section 6.03. Limitations on Distributions. Notwithstanding anything to the contrary contained in this Agreement, distributions to Members shall be subject to the restrictions contained in §18-607 of the Delaware LLC Act.

Section 6.04. Withholding.

(a) Authority to Withhold; Treatment of Withheld Amounts. Each Member hereby authorizes the Company and the Managing Member on behalf of the Company to withhold and to pay over, or otherwise to pay, any withholding or other taxes payable by the Company (pursuant to any provision of United States federal, state or local or foreign law) with respect to such Member or as a result of such Member’s participation in the Company; and if and to the extent that the Company shall be required to withhold or pay any such withholding or other taxes, such Member shall be deemed for all purposes of this Agreement to have received a payment from the Company as of the time such withholding or other tax is paid, which payment shall be deemed to be a distribution with respect to such Member’s Membership Interest in the Company.

(b) Indemnification. Each Member shall, to the fullest extent permitted by Applicable Law, indemnify and hold harmless the Managing Member and each other Person (other than the Company) who is or who is deemed to be the responsible withholding agent for United States federal, state or local or foreign income tax purposes against all claims, liabilities and expenses of whatever nature (other than any claims, liabilities and expenses in the nature of penalties and accrued interest thereon that result from such Managing Member’s or such other Person’s gross negligence, willful misconduct or fraud) relating to the Company’s, the Managing Member’s or such other Person’s obligation to withhold and to pay over, or otherwise to pay, any withholding or other taxes payable by the Company or any of its Affiliates with respect to such Member or as a result of such Member’s participation in the Company.

(c) Refunds. In the event that the Company receives a refund of taxes previously withheld, the economic benefit of such refund shall be apportioned among the Members in a manner reasonably determined by the Managing Member to offset the prior operation of this Section 6.04 in respect of such withheld taxes.

Section 7.03. Allocations of Net Profits and Net Losses. Subject to Section 7.04, Net Profits or Net Losses for any Fiscal Year or other period shall be allocated to the Members in proportion to their respective Percentage Interests.

Section 7.04. Special Allocations.

(a) Notwithstanding any other provision of this Agreement, the following allocations shall be made for each Fiscal Year or other period:

(i) Notwithstanding any other provision of this Section 7.04, if there is a net decrease in Company Minimum Gain during any taxable period, each Member shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treas. Reg. § 1.704-2(f), (g)(2) and (j). For purposes of this Section 7.04, each Member’s Capital Account shall be determined and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Article 6 with respect to such taxable period. This Section 7.04(a)(i) is intended to comply with the partnership minimum gain chargeback requirement in Treas. Reg. § 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Notwithstanding the other provisions of this Section 7.04 (other than 7.04(a)(i) above), if there is a net decrease in Member Nonrecourse Debt Minimum Gain

during any taxable period, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treas. Reg. § 1.704-2(i)(4) and (j)(2). For purposes of this Section 7.04, each Member’s Adjusted Capital Account balance shall be determined, and the allocation of income and gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 7.04(a), other than Section 7.04(a)(i) above, with respect to such taxable period. This Section 7.04(a)(ii) is intended to comply with the Member nonrecourse debt minimum gain chargeback requirement in Treas. Reg. § 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Except as provided in Sections 7.04(a)(i) and 7.04(a)(ii) above, in the event any Member unexpectedly receives any adjustments, allocations or distributions described in Treas. Reg. § 1.704-1(b)(2)(ii)(d)(4), (5) or (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 such Treasury Regulations, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Sections 7.04(a)(i) and 7.04(a)(ii).

(iv) In the event any Member has a deficit balance in its Adjusted Capital Account at the end of any 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, however, that an allocation pursuant to this Section 7.04(a)(iv) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 7.04(a) have been tentatively made as if this Section 7.04(a)(iv) were not in this Agreement.

(v) Nonrecourse Deductions for any taxable period shall be allocated to the Members in accordance with their Percentage Interests.

(vi) Member Nonrecourse Deductions for any taxable period shall be allocated 100% to the Member that bears the Economic Risk of Loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treas. Reg. § 1.704-2(i). If more than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Members in accordance with the ratios in which they share such Economic Risk of Loss.

(b) Curative Allocation. The allocations set forth in Section 7.04(a) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Company

income, gain, loss, or deduction pursuant to this Section 7.04(b). Therefore, notwithstanding any other provision of this Article 7 (other than the Regulatory Allocations), but subject to the Code and the Treasury Regulations, the Managing Member shall make such offsetting special allocations of Company income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of the Agreement. In exercising its discretion under this Section 7.04(b), the Managing Member shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

(c) Notwithstanding any other provisions of this Section 7.04, if, following the application of Sections 7.04(a) and 7.04(b), the Managing Member determines in its sole discretion that the allocation provisions in Sections 7.04(a) and 7.04(b) do not reflect the economic arrangements among the Members, then Net Profits and Net Losses shall, following the application of Sections 7.04(a) and 7.04(b), be allocated in the sole discretion of the Managing Member in a manner that the Managing Member concludes reflects the economic arrangements of the Members.

Section 7.05. Allocation for Income Tax Purposes.

(a) Except as provided in Section 7.05(b), 7.05(c) and 7.05(d), each item of income, gain, loss and deduction of the Company for U.S. federal income tax purposes shall be allocated among the Members in the same manner as such items are allocated for book purposes under Sections 7.03 and 7.04.

(b) The Members recognize that there may be a difference between the Book Value of a Company asset and the asset’s adjusted tax basis at the time of the property’s contribution or revaluation pursuant to this Agreement. In such a case, all items of tax depreciation, cost recovery, amortization, and gain or loss with respect to such asset shall be allocated among the Members to take into account the disparities between the Book Values and the adjusted tax basis with respect to such properties in accordance with the provisions of Sections 704(b) and 704(c) of the Code and the Treasury Regulations under those sections; provided, however, that any tax items not required to be allocated under Sections 704(b) or 704(c) of the Code shall be allocated in the same manner as such gain or loss would be allocated for book purposes under Sections 7.03 and 7.04.

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

(d) If any deductions for depreciation, cost recovery or depletion are recaptured as ordinary income upon the sale or other disposition of Company properties, the ordinary income character of the gain from such sale or disposition shall be allocated among the Members in the same ratio as the deductions giving rise to such ordinary income character were allocated.

Section 7.06. Other Allocation Rules. All items of income, gain, loss, deduction and credit allocable to Membership Interests that have been transferred shall be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as the owner of such Membership Interests, without regard to the results of Company operations during any particular portion of that calendar year and without regard to whether cash distributions were made to the transferor or the transferee during that calendar year; provided, however, that this allocation must be made in accordance with a method permissible under Code Section 706 and the regulations thereunder.

Section 7.07. Certain Costs And Expenses. The Company shall (a) pay, or cause to be paid, all costs, fees, operating expenses and other expenses of the Company (including the costs, fees and expenses of attorneys, accountants or other professionals and the compensation of all personnel providing services to the Company) incurred in pursuing and conducting, or otherwise related to, the business of the Company, and (b) in the sole discretion of the Managing Member, reimburse the Managing Member for any out-of-pocket costs, fees and expenses incurred by it in connection therewith. To the extent that the Managing Member reasonably determines in good faith that its expenses are related to the business conducted by the Company and/or its subsidiaries (including any good faith allocation of a portion of expenses that so relate to the business of the Company and/or its subsidiaries and that also relate to other businesses or activities of the Managing Member), then the Managing Member may cause the Company to pay or bear all such expenses of the Managing Member, including, costs of securities offerings not borne directly by Members, compensation and meeting costs of its board of directors, cost of periodic reports to its stockholders, litigation costs and damages arising from litigation, accounting and legal costs and franchise taxes (which are not based on, or measured by, income) provided that the Company shall not pay or bear any income tax obligations of the Managing Member; provided further that the payment of Tax Distributions to the Managing Member shall not be prevented by the foregoing. Payments under this Section 7.07 are intended to constitute reasonable compensation for past or present services and are not “distributions” within the meaning of §18-607 of the Delaware LLC Act.

Section 10.01. Transfer of Membership Interests. Other than as provided for below in this Section 10.01 or in Section 10.02, no Member may sell, assign, transfer, grant a participation in, pledge, hypothecate, encumber or otherwise dispose of (such transaction being herein

collectively called a “Transfer”) all or any portion of its Membership Interest except with the written consent of the Managing Member, which may be granted or withheld in its sole discretion. Without the consent of the Managing Member (but otherwise in compliance with Sections 9.01 and 9.02), a Member may, at any time, (a) Transfer any portion of such Member’s Membership Interest pursuant to the Exchange Agreement, and (b) Transfer any portion of such Member’s Membership Interest to a Permitted Transferee of such Member. Any Transfer of Series B Membership Interests to a Permitted Transferee of such Member must be accompanied by the transfer of an equal number of corresponding Class B Shares to such Permitted Transferee. Any purported Transfer of all or a portion of a Member’s Membership Interest not complying with this Section 10.01 shall be void ab initio and shall not create any obligation on the part of the Company or the other Members to recognize that purported Transfer or to recognize the Person to which the Transfer purportedly was made as a Member. A Person acquiring a Member’s Membership Interest pursuant to this Section 10.01 shall not be admitted as a substituted or additional Member except in accordance with the requirements of Section 10.04, but such Person shall, to the extent of the Membership Interest transferred to it, be entitled to such Member’s (i) share of distributions, (ii) share of profits and losses, including Net Profits and Net Losses, and (iii) Capital Account in accordance with Section 7.01(a). Notwithstanding anything in this Section 10.01 or elsewhere in this Agreement to the contrary, if a Member Transfers all or any portion of its Membership Interest after the designation of a record date and declaration of a distribution pursuant to Section 6.01 and before the payment date of such distribution, the transferring Member (and not the Person acquiring all or any portion of its Membership Interest) shall be entitled to receive such distribution in respect of such transferred Membership Interest.

Section 10.02. Transfer of WIND’s Interest. WIND may not Transfer all or any portion of its Membership Interest held in the form of Series A Membership Interests at any time.

Section 10.03. Lock Up. The Members (other than WIND and any Member party to an underwriting or lock-up agreement with the IPO Underwriters) may not, from the date hereof and until 180 days after the date of the IPO Underwriting Agreement (as such 180-day period may be extended pursuant to Section 5(k) of the IPO Underwriting Agreement), offer, sell, contract to sell, pledge, Transfer or otherwise dispose of, directly or indirectly, any Class A Shares, Class B Shares or Series B Membership Interests issued pursuant to the Merger Agreement, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such Class A Shares, Class B Shares or Series B Membership Interests, whether any such aforementioned transaction is to be settled by delivery of such Class A Shares, Class B Shares or Series B Membership Interests or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of WIND (which consent may be withheld in its sole discretion).

Section 10.04. Recognition of Transfer; Substituted and Additional Members. (a) No direct or indirect Transfer of all or any portion of a Member’s Membership Interest may be made, and no purchaser, assignee, transferee or other recipient of all or any part of such Membership Interest shall be admitted to the Company as a substituted or additional Member hereunder, unless:

(i) the provisions of Section 10.01 or Section 10.02, as applicable, shall have been complied with;

(ii) in the case of a proposed substituted or additional Member (other than a Permitted Transferee described in clauses (i) through (iv) of the definition thereof) that is (i) a competitor or potential competitor of WIND, the Company or their Subsidiaries, (ii) a Person with whom the WIND, the Company or their Subsidiaries has had or is expected to have a material commercial or financial relationship or (iii) likely to subject WIND, the Company or their Subsidiaries to any material legal or regulatory requirement or obligation, or materially increase the burden thereof, in each case as determined by the Managing Member in its sole discretion, the admission of the purchaser, assignee, transferee or other recipient as a substituted or additional Member shall have been approved by the Managing Member;

(iii) the Managing Member shall have been furnished with the documents effecting such Transfer, in form and substance reasonably satisfactory to the Managing Member, executed and acknowledged by both the seller, assignor or transferor and the purchaser, assignee, transferee or other recipient, and the Managing Member shall have executed (and the Managing Member hereby agrees to execute) any other documents on behalf of itself and the Members required to effect the Transfer;

(iv) the provisions of Section 10.04(b) shall have been complied with;

(v) the Managing Member shall be reasonably satisfied that such Transfer will not (A) result in a violation of the Securities Act or any other Applicable Law; or (B) cause an assignment under the Investment Company Act;

(vi) such Transfer would not cause the Company to lose its status as a partnership for federal income tax purposes and, without limiting the generality of the foregoing, such Transfer shall not be effected on or through an “established securities market” or a “secondary market or the substantial equivalent thereof,” as such terms are used in Section 1.7704-1 of the Treasury Regulations;

(vii) the Managing Member shall have received the opinion of counsel, if any, required by Section 10.04(c) in connection with such Transfer; and

(viii) all necessary instruments reflecting such Transfer and/or admission shall have been filed in each jurisdiction in which such filing is necessary in order to qualify the Company to conduct business or to preserve the limited liability of the Members.

(b) Each substituted Member and additional Member shall be bound by all of the provisions of this Agreement. Each substituted Member and additional Member, as a condition to its admission as a Member, shall execute and acknowledge such instruments (including a counterpart of this Agreement or a joinder agreement in customary form), in form and substance reasonably satisfactory to the Managing Member, as the Managing Member reasonably deems necessary or desirable to effectuate such admission and to confirm the agreement of such substituted or additional Member to be bound by all the terms and provisions of this Agreement with respect to the Membership Interest acquired by such substituted or additional Member. The admission of a substituted or additional Member shall not require the consent of any Member other than the Managing Member (if and to the extent such consent of the Managing Member is expressly required by this Article 10). As promptly as practicable after the admission of a substituted or additional Member, the books and records of the Company and Exhibit A shall be changed to reflect such admission.

(c) As a further condition to any Transfer of all or any part of a Member’s Membership Interest, the Managing Member may, in its discretion, require a written opinion of counsel to the transferring Member reasonably satisfactory to the Managing Member, obtained at the sole expense of the transferring Member, reasonably satisfactory in form and substance to the Managing Member, as to such matters as are customary and appropriate in transactions of this type, including, without limitation (or, in the case of any Transfer made to a Permitted Transferee, limited to an opinion) to the effect that such Transfer will not result in a violation of the registration or other requirements of the Securities Act or any other federal or state securities laws. No such opinion, however, shall be required in connection with a Transfer made pursuant to the Exchange Agreement.

Section 10.05. Expense of Transfer; Indemnification. All reasonable costs and expenses incurred by the Managing Member and the Company in connection with any Transfer of a Member’s Membership Interest, including any filing and recording costs and the reasonable fees and disbursements of counsel for the Company, shall be paid by the transferring Member. In addition, the transferring Member hereby indemnifies the Managing Member and the Company against any losses, claims, damages or liabilities to which the Managing Member, the Company, or any of their Affiliates may become subject arising out of or based upon any false representation or warranty made by, or breach or failure to comply with any covenant or agreement of, such transferring Member or such transferee in connection with such Transfer.

Section 10.06. Exchange Agreement. In connection with any Transfer of any portion of a Member’s Membership Interest pursuant to the Exchange Agreement, the Managing Member shall cause the Company to take any action as may be required under the Exchange Agreement or requested by any party thereto to effect such Transfer promptly.

(c) 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 distributed as provided in this Section 11.01 and any filings required by the Delaware LLC Act have been made.

The Managing Member or a Person selected by the Managing Member to act as liquidating trustee, shall wind up the affairs of the Company pursuant to this Agreement. The Managing Member or liquidating trustee, as applicable, is authorized, subject to the Delaware LLC Act, to sell, exchange or otherwise dispose of the assets of the Company, or to distribute Company assets in kind, as the Managing Member or liquidating trustee shall determine to be in the best interests of the Members.

The Managing Member or liquidating trustee may consult with counsel and accountants with respect to winding up the Company and distributing its assets and shall be justified in acting or omitting to act in accordance with the advice or opinion of such counsel or accountants, provided that the Managing Member or liquidating trustee shall have used reasonable care in selecting such counsel or accountants.

(e) Upon dissolution of the Company, the expenses of liquidation (including compensation for the services of the liquidating trustee and legal and accounting fees and expenses) and the Company’s liabilities and obligations to creditors shall be paid, or reasonable provisions shall be made for payment thereof, in accordance with Applicable Law, from cash on hand or from the liquidation of Company properties.

(f) A reasonable time shall be allowed for the orderly winding up of the business and affairs of the Company and the liquidation of its assets pursuant to this Section 11.01 to minimize any losses otherwise attendant upon such winding up. Notwithstanding the generality of the foregoing, within 180 calendar days after the effective date of dissolution of the Company, the assets of the Company shall be distributed in the following manner and order: (i) all debts and obligations of the Company, if any, shall first be paid, discharged or provided for by adequate reserves; and (ii) the balance shall be distributed to the Members in accordance with Section 6.01.

ARTICLE 12

EXCULPATION AND INDEMNIFICATION

Section 12.01. Exculpation. To the fullest extent permitted by Applicable Law, and except as otherwise expressly provided herein, no Indemnitee shall be liable to the Company or any other Indemnitee for any Losses, which at any time may be imposed on, incurred by, or asserted against, the Company or any other Indemnitee as a result of or arising out of the

activities of the Indemnitee on behalf of the Company to the extent within the scope of the authority reasonably believed by such Indemnitee to be conferred on such Indemnitee, except to the extent such Losses arise out of (i) the Indemnitee’s failure to act in good faith and in a manner such Indemnitee believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal proceeding, the Indemnitee’s not having any reasonable cause to believe such conduct was unlawful, (ii) the Indemnitee’s material breach of this Agreement or any other Transaction Document, or (iii) the Indemnitee’s gross negligence or willful misconduct.

Section 12.02. Indemnification. To the fullest extent permitted by Applicable Law, each of (a) the Members, the Managing Member and their respective Affiliates, (b) the stockholders, members, managers, directors, officers, partners, employees and agents of the Members and the Managing Member and their respective Affiliates, and (c) the officers of the Company (each, an “Indemnitee”) shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities, expenses (including legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (collectively, “Losses”), which at any time may be imposed on, incurred by, or asserted against, the Indemnitee as a result of or arising out of this Agreement, the Company, its assets, business or affairs or the activities of the Indemnitee on behalf of the Company to the extent within the scope of the authority reasonably believed to be conferred on such Indemnitee; provided, however, that the Indemnitee shall not be entitled to indemnification for any Losses to the extent such Losses arise out of (i) the Indemnitee’s failure to act in good faith and in a manner such Indemnitee believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal proceeding, the Indemnitee’s not having any reasonable cause to believe such conduct was unlawful, (ii) the Indemnitee’s material breach of this Agreement or any other Transaction Document, or (iii) the Indemnitee’s gross negligence or willful misconduct. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that the Indemnitee acted in a manner specified in clause (i), (ii) or (iii) above. Any indemnification pursuant to this Article 12 shall be made only out of the assets of the Company and no Member shall have any personal liability on account thereof.

Section 12.03. Expenses. Expenses (including reasonable legal fees and expenses) incurred by an Indemnitee in defending any claim, demand, action, suit or proceeding described in Section 12.02 shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding, upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as provided in this Article 12.

Section 12.04. Non-Exclusivity. The indemnification and advancement of expenses set forth in this Article 12 shall not be exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, the Delaware LLC Act, this Agreement, any other agreement, a policy of insurance or otherwise. The

indemnification and advancement of expenses set forth in this Article 12 shall continue as to an Indemnitee who has ceased to be a named Indemnitee and shall inure to the benefit of the heirs, executors, administrators, successors and permitted assigns of such a Person.

Section 12.05. Insurance. The Company may purchase and maintain insurance on behalf of the Indemnitees against any liability asserted against them and incurred by them in such capacity, or arising out of their status as Indemnitees, whether or not the Company would have the power to indemnify them against such liability under this Article 12.

(a) to adopt the calendar year as the Company’s taxable year or Fiscal Year, if permitted under the Code;

(b) to adopt the accrual method of accounting and to keep the Company’s books and records on the U.S. federal income tax method;

(d) as required by the Tax Receivable Agreement, to make an election under Code Section 754 with respect to the Company (and to cause each Subsidiary Partnership to make such an election under Code Section 754), which elections shall be in effect for each Fiscal Year in which any Sponsor Transfers Series B Membership Interests pursuant to the Exchange Agreement; and

(e) any other election the Managing may deem appropriate and in the best interests of the Members.

Section 13.05. Tax Matters Member.

(a) The Managing Member shall be the “tax matters partner” of the Company as defined in Code Section 6231(a)(7) (the “Tax Matters Member”). The Tax Matters Member shall take such action as may be necessary to cause to the extent possible each other Member to become a notice partner within the meaning of Code Section 6231 (a)(8). The Tax Matters Member shall inform each other Member of all significant matters that may come to its attention in its capacity as Tax Matters Member by giving notice thereof on or before the fifth day after becoming aware thereof and, within that time, shall forward to each other Member copies of all significant written communications it may receive in that capacity.

(b) Any cost or expense incurred by the Tax Matters Member in connection with its duties, including the preparation for or pursuance of administrative or judicial proceedings, shall be paid by the Company.

(c) Any Member that enters into a settlement agreement with respect to any partnership item (within the meaning of Code Section 6231(a)(3)) shall notify the other Members of such settlement agreement and its terms within 90 days from the date of the settlement.

(d) No Member shall file a request pursuant to Code Section 6227 for an administrative adjustment of partnership items for any taxable year without first notifying the other Members. If the Managing Member consents to the requested adjustment, the Tax Matters Member shall file the request for the administrative adjustment on behalf of the Members. If such consent is not obtained within 30 days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member, including the Tax Matters Member, may file a request for administrative adjustment on its own behalf. Any Member intending to file a petition under Code Sections 6226 or 6228 or other Code Section with respect to any item involving the Company shall notify the other Members of such intention and the nature of the contemplated proceeding. In the case where the Tax Matters Member is the Member intending to

file such petition on behalf of the Company, such notice shall be given within a reasonable period of time to allow the other Members to participate in the choosing of the forum in which such petition will be filed.

(e) If any Member intends to file a notice of inconsistent treatment under Code Section 6222(b), such Member shall give reasonable notice under the circumstances to the other Members of such intent and the manner in which the Member’s intended treatment of an item is (or may be) inconsistent with treatment of that item by the other Members.

ARTICLE 14

ARBITRATION

The Members shall attempt in good faith to resolve all claims, disputes and other disagreements arising hereunder or under the Exchange Agreement (each, a “Dispute”) by negotiation. If a Dispute cannot be resolved in such manner, such Dispute shall, at the request of any party, after providing written notice to the other parties to the Dispute, be submitted to arbitration in The City of New York in accordance with the Commercial Arbitration Rules of the American Arbitration Association then in effect. The proceeding shall be confidential. The party initially asserting the Dispute (the “Initiating Party”) shall notify the other party (the “Responding Party”) of the name and address of the arbitrator chosen by the Initiating Party and shall specifically describe the Dispute in issue to be submitted to arbitration. Within 30 days of receipt of such notification, the Responding Party shall notify the Initiating Party of its answer to the Dispute, any counterclaim which it wishes to assert in the arbitration and the name and address of the arbitrator chosen by the Responding Party. If the Responding Party does not appoint an arbitrator during such 30-day period, appointment of the second arbitrator shall be made by the American Arbitration Association upon request of the Initiating Party. The two arbitrators so chosen or appointed shall choose a third arbitrator, who shall serve as president of the panel of arbitrators (the “Panel”) thus composed. If the two arbitrators so chosen or appointed fail to agree upon the choice of a third arbitrator within 30 days from the appointment of the second arbitrator, the third arbitrator will be appointed by the American Arbitration Association upon the request of the arbitrators or either of the parties. In all cases, the arbitrators must be persons who are knowledgeable about, and have recognized ability and experience in dealing with, the subject matter of the Dispute. The arbitrators will act by majority decision. Any decision of the arbitrators shall (a) be rendered in writing and shall bear the signatures of at least two arbitrators, and (b) identify the members of the Panel. Absent fraud or manifest error, any such decision of the Panel shall be final, conclusive and binding on the parties to the arbitration and enforceable by a court of competent jurisdiction. The expenses of the arbitration shall be borne equally by the parties to the arbitration; provided, however, that each party shall pay for and bear the costs of its own experts, evidence and legal counsel, unless the arbitrator rules otherwise in the arbitration. The parties shall complete all discovery within 30 days after the Panel is composed, shall complete the presentation of evidence to the Panel within 15 days after the completion of discovery, and a final decision with respect to the matter submitted to

arbitration shall be rendered within 15 days after the completion of presentation of evidence. The parties shall cause to be kept a record of the proceedings of any matter submitted to arbitration hereunder.

ARTICLE 15

Member holding Series B Membership Interests, such amendment or waiver may only be made by the Managing Member upon the prior written consent of such disproportionately and adversely affected Member, (ii) to the extent any amendment or waiver, including any amendment or waiver of the Exhibits attached hereto, would disproportionately and adversely affect the rights of holders of Series B Membership Interests compared with the rights of holders of Series A Membership Interests or any other series or class of Membership Interest, such amendment or waiver may only be made by the Managing Member upon the prior written consent of the Majority Holders, and (iii) the following provisions may not be amended by the Managing Member in any manner adverse to a Member holding Series B Membership Interests without the prior written consent of the Majority Holders: Section 6.01, Section 6.02, Article 7, Section 8.02, Section 10.04(a)(vi), Section 13.02, Section 13.03, Section 13.04(d) and Section 15.04.

Each of the parties irrevocably waives, to the fullest extent permitted by law, any objection or defense that it may now or hereafter have based on venue, inconvenience of forum, the lack of personal jurisdiction and the adequacy of service of process (as long as the party was provided Notice in accordance with the methods specified in Section 15.08) in any suit, action or proceeding brought in such courts.

Section 15.11. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.
