(b) Waiver of Notice. No notice of any meeting of Members need be given to any Member who submits a signed waiver of notice, whether before or after the meeting. Neither the business to be transacted at, nor the purpose of, any meeting of the Members need be specified in a written waiver of notice. The attendance of any Member at a meeting of Members shall constitute a waiver of notice of such meeting, except when the Member attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business on the ground that the meeting has not been lawfully called or convened.

(c) Quorum. Except as otherwise required by applicable law or by the Certificate, the presence in person or by proxy of the owners of record of a Majority-in-Interest shall constitute a quorum for the transaction of business at a meeting of Members.

(d) Voting. If the Managing Member has fixed a record date, every Member shall be entitled to such number of votes as is equal to the Ownership Percentage of such Member at the close of business on such record date. If no record date has been so fixed, then every Member shall be entitled to such number of votes as is equal to the Ownership Percentage of such Member on the close of business on the day preceding the day on which notice of the meeting is given or the first consent in respect of the applicable action is executed and delivered to the Company, or, if notice is waived, at the close of business on the day preceding the day on which the meeting is held. Except as otherwise required by applicable law or the Certificate, the vote of a Majority-in-Interest at any meeting at which a quorum is present shall be sufficient for the transaction of any business at such meeting.

(e) Proxies. Each Member may authorize any Person to act for such Member by proxy on all matters in which a Member is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting. Every proxy must be signed by the Member or such Member’s attorney-in-fact. No proxy shall be valid after the expiration of three years from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the Member executing it unless otherwise provided in such proxy; provided, that such right to revocation shall not invalidate or otherwise affect actions taken under such proxy prior to such revocation.

Unless otherwise provided in this Agreement, any action that may be taken at any meeting of the Members may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the number of Members necessary to take such action in accordance with the terms of this Agreement.

(b) Provision of Credit Support to Benefit Company. To the extent the Managing Member determines that it is necessary or desirable for the Company to post letters of credit or to provide guaranties or other forms of credit support as security for contingent obligations to third parties arising under any debt financing, swap, cap, floor, collar or other hedging arrangements or similar financial transactions or in order to secure the performance of the Company or any of its Subsidiaries under any contract (collectively, “Company Credit Support”), then the Managing Member may post or provide any Company Credit Support on behalf or for the benefit of the Company. In the event that the Managing Member provides such Company Credit Support, the Company shall pay to the Managing Member on the last day of each calendar quarter, a fee in an amount equal to 12.99% per annum on the maximum undrawn amount of each item of Company Credit Support during such quarter. Subject to the last sentence of this Section 4.4(b), the Members shall be deemed to have made an Additional Capital Contribution for all purposes under this Agreement, including the crediting of amounts to Capital Accounts, on a pro rata basis in accordance with their respective Ownership Percentages in the event that any Company Credit Support posted, provided or otherwise procured by the Managing Member pursuant to this Section 4.4(b) is drawn. Each Non-Managing Member hereby agrees to pay the Managing Member an amount equal to such Non-Managing Member’s pro rata share of any Additional Capital Contribution deemed made pursuant to this Section 4.4(b) promptly following the making of such Additional Capital Contribution. If any such Non-Managing Member fails to repay the Managing Member such Non-Managing Member’s pro rata share of any Additional Capital Contribution deemed made pursuant to this Section 4.4(b) within ten (10) Business Days following notification to such Non-Managing Member by the Managing Member of the making of such deemed Additional Capital Contribution (the Non-Managing Member failing to make such repayment, the “Credit Support Non-Contributing Member”), the Members and the Company shall treat the Credit Support Non-Contributing Member’s deemed Additional Capital Contribution not as an Additional Capital Contribution by such Credit Support Non-Contributing Member in exchange for the issuance of Units but instead as an Additional Capital Contribution by the Managing Member on the date deemed made for all purposes under this Agreement, including the crediting of amounts to Capital Accounts.

(c) Advances by Managing Member.

(i) If the Company requires additional funds for the business or operations of the Company or any of its Subsidiaries and, subject to this Section 4.4(c)(i), the Managing Member determines (A) that a Member Loan is necessary or advisable to advance such required funds to the Company and (B) the amount of the funds required, then the Managing Member may (but shall have no obligation to) advance the required funds, each of which advance shall (w) constitute a loan from the Managing Member to the Company, (x) bear interest at a rate of 12.99% per annum, (y) not be deemed to be a Capital Contribution by the Managing Member to the Company and (z) not be convertible into Units (each such loan, a “Member Loan”); provided, that promptly after the funding of such Member Loan, the Managing Member shall offer to each Non-Managing Member the right to purchase, at par value, such Non-Managing Member’s Ownership Percentage of such Member Loan.

(ii) Repayments of Member Loans shall be made: (A) first, on a pro rata basis to pay accrued interest to the date of such payment on all outstanding Member Loans and (B) second, on a pro rata basis to pay principal due and payable on all outstanding Member Loans. For the avoidance of doubt, any Member Loan shall be a contractual obligation of the Company and amounts payable to the Managing Member thereunder shall reduce Distributable Amounts in accordance with the definition thereof.

14

(b) The provisions of this Section 4.6 shall survive the termination of the Company.

Section 4.7 Other Business for Members. Any Member or Affiliate thereof may engage in or possess an interest in other business ventures of any nature or description, independently or with or on behalf of others, similar or dissimilar to the business of the Company or any of its Subsidiaries, and the Company and the Members shall have no rights by virtue of this Agreement in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Company or any of its Subsidiaries, shall not be deemed wrongful or improper. No Member nor its respective Affiliates will be obligated to present any particular investment opportunity to the Company, even if such opportunity is of a character that, if presented to the Company, could be taken by the Company or any of its Subsidiaries. Furthermore, each Member and each of its respective Affiliates shall have the right to take for such Person’s own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment opportunity without liability to the Company or any other Member.

Any higher valuation or other forms of promote raised from a sale of new Units to a Third-Party Purchaser shall be for the benefit of each Member in proportion to its Ownership Percentage immediately prior to the issuance and sale of new Units to such Third-Party Purchaser.

(d) Exhibit A sets forth the Units owned by each Member as of the Effective Date and shall be revised by the Officers as necessary to reflect changes and adjustments resulting from the issuance, redemption or any Transfer of Units made in accordance with the terms of this Agreement; provided, that a failure to reflect any such issuance, redemption or any Transfer on Exhibit A shall not prevent any such issuance, redemption or any Transfer from being effective.

Section 7.3 Capital Accounts. A capital account (“Capital Account”) shall be established for each Member and shall be maintained as provided in this Article VII and Article VIII. No later than 60 days after the end of each calendar quarter, the Officers shall prepare a statement of the Capital Account balances of the Members as of the end of such calendar quarter.

Section 7.4 Capital Account Adjustments. As of the end of each Accounting Period, the balance in each Member’s Capital Account shall be adjusted by (a) increasing such balance by such Member’s (i) allocable share of Net Profit (allocated in accordance with Article VIII) or other income and gain allocated in accordance with this Agreement, (ii) the amount of cash and the Gross Asset Value of any property (as of the date of the contribution thereof and net of any liabilities encumbering such property) contributed to the Company during such Accounting Period, if any, and (iii) the net amount of any Company liabilities that are assumed by such Member or that are secured by any Company assets distributed to such Member and (b) decreasing such balance by (i) the amount of cash and the Gross Asset Value of any property (as of the date of the distribution thereof and net of any liabilities encumbering such property) distributed to such Member during such Accounting Period, (ii) such Member’s allocable share of Net Loss (allocated in accordance with Article VIII) or other loss and deduction allocated in accordance with this Agreement and (iii) the net amount of any liabilities of such Member that are assumed by the Company or that are secured by any property contributed by such Member to the Company. The provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Sections 1.704-1(b) and 1.704-2 and shall be interpreted and applied in a manner consistent with such Treasury Regulations. In addition, the Capital Accounts shall be increased or decreased upon a revaluation of Company property pursuant to clause (b) of the definition of Gross Asset Value in the manner prescribed in Treasury Regulations Section 1.704-1(b)(2)(iv)(f). In determining the amount of any liability for purposes of this Section 7.4, there shall be taken into account Section 752 of the Code and any other applicable provisions of the Code and the Treasury Regulations. Notwithstanding any provision to the contrary in this Agreement, income and gain of the Company, loss and deductions of the Company, and all other items attributable to any Units Transferred for the Accounting Period in which such Units are Transferred will be divided and allocated between (or among) the affected Persons by taking into account their varying interests during the period in accordance with Code Section 706(d), using any conventions permitted by law and approved by the Managing Member and the parties to such Transfer.

20

Section 7.5 Additional Capital Contributions.

(a) Generally. No Member shall be required to make any Additional Capital Contribution to the Company in respect of the Units then held by such Member except to the extent any Member agrees in writing to fund Additional Capital Contributions. Except as otherwise provided below, Members making Additional Capital Contributions under this Section 7.5 shall receive in respect thereof a number of Units determined by dividing (i) the Additional Capital Contribution being made by such Member by (ii) the Additional Membership Unit Price. Each Unit issued to a Member pursuant to this Section 7.5 will be duly authorized and validly issued in accordance with this Agreement and fully paid (to the extent required by this Agreement) and nonassessable (except as such nonassessability may be affected by matters described in § 18-607 of the Delaware Act).

Section 7.6 Negative Capital Accounts. Except as required by law, no Member shall be required to make up a negative balance in its Capital Account.

Section 7.7 Assignee Capital Accounts. The original Capital Account established for any Person who acquires Units by virtue of a Transfer in accordance with the terms of this Agreement shall be in the same amount as, and shall replace, the Capital Account of the assignor of such Units. To the extent such Person acquires less than all of the Units of the assignor, the initial Capital Account of such Person shall be in proportion to the Units owned by the assignor immediately before such Transfer, and the Capital Account of the assignor who retains any Units shall be reduced correspondingly.

ARTICLE VIII.

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. This Section 8.2(b) is intended to comply with the provisions of Treasury Regulations Section 1.7042(i) and shall be interpreted consistently therewith.

(e) Qualified Income Offset. Except as provided in Section 8.2(c) and Section 8.2(d) above, in the event any Member unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall be allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by such Treasury Regulation, the deficit balance, if any, in its Adjusted Capital Account created by such adjustment, allocation or distribution as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Section 8.2(c) or Section 8.2(d). This Section 8.2(e) is intended to constitute a qualified income offset described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(f) Gross Income Allocation. In the event any Member has a deficit balance in its Adjusted Capital Account at the end of any Accounting Period, such Member shall be 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 8.2(f) 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 8.2 (other than Section 8.2(e)) have been tentatively made as if Section 8.2(e) and this Section 8.2(f) were not in this Agreement.

(g) Regulatory Allocations. The allocations set forth in this Section 8.2 (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 8.2(g). Therefore, notwithstanding any other provision of this Article VIII (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 this Agreement. In exercising its discretion under this Section 8.2(g), the Managing Member shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

Section 8.3 Income Tax Allocations.

(a) Except as provided in this Section 8.3, each item of income, gain, loss and deduction of the Company for federal income tax purposes shall be allocated among the Members in the same manner as such items are allocated for book purposes under Section 8.1 and Section 8.2.

(b) In accordance with Code Section 704(c) and applicable Treasury Regulations, income, gain, loss and deduction with respect to any property contributed to the Company (or any predecessor thereto) that has a Gross Asset Value that is different from its adjusted tax basis shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company (or any predecessor thereto) for U.S. federal income tax purposes and the fair market value of such property for U.S. federal income tax purposes at the time of contribution. If the Gross Asset Value

23

of any Company property is adjusted in accordance with clause (c) or (d) of the definition of Gross Asset Value, then subsequent allocations of income, gain, loss and deduction shall take into account any variation between the adjusted basis of such property for federal income tax purposes and its Gross Asset Value as provided in Code Section 704(c) and the related Treasury Regulations. The allocations described in this Section 8.3 shall be made using any method permitted under Treasury Regulations Section 1.704-3 as determined by the Managing Member.

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

ARTICLE IX.

DISTRIBUTIONS

Section 9.1 Distributions Generally. Distributable Amounts (as hereinafter defined) shall be distributed within 30 Business Days after the end of each calendar quarter or at any other time determined by the Managing Member to the Members pro rata according to their relative Ownership Percentages.

The term “ Distributable Amounts” means the amount of cash on hand from time to time in excess of amounts required, as reasonably determined by the Managing Member, to pay or provide for payment of existing and projected obligations (including fees and expenses payable under this Agreement or any other contract), capital expenditures, acquisitions and the reasonably anticipated needs of the Company and its Subsidiaries and to provide a reasonable reserve for working capital and contingencies for the next calendar quarter.

Section 9.2 Distributions in Kind. In the event of a distribution of Company property, such property shall for all purposes of this Agreement be deemed to have been sold at its fair market value, as determined by the Managing Member, and the proceeds of such sale shall be deemed to have been distributed to the Members.

Section 9.3 No Withdrawal of Capital. Except as otherwise expressly provided in this Article IX or Article XIII, no Member shall have the right to withdraw capital from the Company or to receive any distribution or return of such Member’s Capital Contributions.

Section 9.4 Withholding. All amounts withheld or paid pursuant to the Code or any provision of any foreign, state or local tax law or treaty with respect to any payment, distribution or allocation to the Company, its Subsidiaries or the Members (including any Company Level Taxes or similar taxes paid by a Subsidiary of the Company with respect to items of income, gain, loss, deduction or credit allocable or attributable to the Members) shall be treated as amounts distributed to the Members pursuant to this Article IX for all purposes of this Agreement. The Managing Member is authorized to withhold from distributions, or with respect to allocations, to the Members and to pay over to any federal, foreign, state or local government any amounts required to be so withheld or paid pursuant to the Code or any provision of any other federal, foreign, state or local law or treaty and shall allocate the burden of such amounts to those Members with respect to which such amounts are specifically attributable, as determined by the Managing

24

Member. Each Member hereby agrees to indemnify and hold harmless the Company, the other Members, and the Tax Matters Representative from and against any liability (including any liability for Company Level Taxes or similar taxes paid by a Subsidiary of the Company) with respect to income attributable to, or distributions or other payments to, such Member. Notwithstanding any other provision of this Agreement, (a) any Person who ceases to be a Member shall be treated as a Member for purposes of this Section 9.4 and (b) the obligations of a Member pursuant to this Section 9.4 shall survive indefinitely with respect to any taxes withheld or paid by the Company or a Subsidiary of 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. Any determinations made by the Managing Member pursuant to this Section 9.4 shall be binding upon the Members.

Section 9.5 Restricted Distributions. Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Member on account of its Units in the Company if that distribution would violate Section 18-607 of the Delaware Act or other applicable law or any Financing Agreement Transaction Documents.

ARTICLE X.

BOOKS AND RECORDS

Section 10.1 Books, Records and Financial Statements.

Each Member shall furnish to the Company all pertinent information in its possession relating to the Company’s operations that is necessary to enable the Company’s tax returns to be timely prepared and filed.

The expenses, if any, that the Tax Matters Representative incurs in fulfilling its covenants pursuant to this Section 10.2 shall be expenses of the Company. The Tax Matters Representative will, within 10 days after the receipt of any notice regarding an audit or tax examination of the Company or any Subsidiary of the Company or any request for material information regarding the Company or any Subsidiary of the Company by United States federal, state, local or other tax authorities (“Tax-Authority Notice”), forward to each Member a photocopy of such Tax-Authority Notice and any material correspondence relating to the Company received from the relevant tax authority. The Tax Matters Representative will, within 10 days thereof, advise each Member in writing of the substance of any conversation affecting the Company held with any representative of the relevant tax authority. The Tax Matters Representative is authorized to take such actions and to execute and file all statements and forms on behalf of the Company that are permitted or required by the applicable provisions of the Bipartisan Budget Act (including a “push-out” election under Section 6226 of the Code or any analogous election under state or local tax law). Each Member agrees to cooperate with the Tax Matters Representative and to do or refrain from doing any or all things requested by the Tax Matters Representative (including paying any and all resulting taxes, additions to tax, penalties and interest in a timely fashion) in connection with any examination of the Company’s affairs by any federal, state, or local tax authorities, including resulting administrative and judicial proceedings. No Member shall have any claim against the Tax Matters Representative for any actions taken (or any failures to take action) by the Tax Matters Representative pursuant to this Section 10.2(b).

References to the Code or Treasury Regulations promulgated thereunder shall be deemed to refer to corresponding provisions that may become applicable under state, local or foreign income tax statutes and regulations.

(ii) For purposes of determining the Net Profit, Net Loss or any other items allocable to any period, Net Profit, Net Loss and any such other items shall be determined on a daily, monthly or other basis, as determined by the Managing Member using any method that is permissible under Section 706 of the Code and the Treasury Regulations thereunder.

ARTICLE XI.

LIABILITY, EXCULPATION AND INDEMNIFICATION

Section 11.1 Liability. Except as otherwise provided by the Delaware Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Covered Person shall be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Covered Person.

Section 11.2 Exculpation. No Covered Person shall be liable to the Company or any other Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Covered Person in good faith and reasonably believed to be in, or not opposed to, the best interests of the Company, except that a Covered Person shall be liable for any such loss, damage or claim incurred by reason of such Covered Person’s gross negligence, willful misconduct or willful breach of this Agreement.

27

Section 11.3 Fiduciary Duty. Any duties (including fiduciary duties) of a Covered Person to the Company or to any other Covered Person that would otherwise apply at law or in equity are hereby eliminated to the fullest extent permitted under the Delaware Act and any other applicable law; provided, that (a) the foregoing shall not eliminate the obligation of each Covered Person to act in compliance with the express terms of this Agreement and (b) the foregoing shall not be deemed to eliminate the implied contractual covenant of good faith and fair dealing. A Covered Person acting under this Agreement shall not be liable to the Company or to any other Covered Person for its good faith reliance on the provisions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, each of the Members hereby acknowledges and agrees that the Managing Member, in determining whether or not to make any particular decision for which the Managing Member’s consent is required, may act in and consider the best interests of itself and its Affiliates and shall not be required to act in or consider the best interests of the Company, any of its Subsidiaries or the other Members.

Section 11.4 Indemnification. To the fullest extent permitted by applicable law, a Covered Person shall be entitled to indemnification from the Company for any loss, damage or claim incurred by such Covered Person by reason of any act or omission performed or omitted by such Covered Person in good faith and reasonably believed to be in, or not opposed to, the best interests of the Company. THIS INDEMNITY SHALL APPLY TO MATTERS THAT ARISE OUT OF THE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF ANY SUCH COVERED PERSON; PROVIDED, HOWEVER, that no Covered Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Covered Person by reason of such Covered Person’s gross negligence, willful misconduct or willful breach of this Agreement with respect to such acts or omissions. Any indemnity under this Section 11.4 shall be provided out of and to the extent of Company assets only, and no Covered Person shall have any personal liability on account thereof.

To the fullest extent permitted by applicable law, expenses (including reasonable attorneys’ fees, disbursements, fines and amounts paid in settlement) incurred by a Covered Person in defending any claim, demand, action, suit or proceeding relating to or arising out of its performance of its duties on behalf of the Company 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 Covered Person to repay such amount if it shall ultimately be determined by a court of competent jurisdiction that the Covered Person is not entitled to be indemnified as authorized in Section 11.4.

Section 11.6 Nonexclusivity; Severability. The exculpation and indemnification provisions set forth in this Agreement shall not be deemed to be exclusive and shall be in addition to any such rights provided by contract, agreement or organizational document of any Subsidiary to which any Covered Person may be entitled. To the fullest extent permitted by applicable law, if any portion of this Article XI shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify the Managing Member and each Officer, as applicable, and may indemnify each employee or agent, as applicable, of the Company as to costs, charges and expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Company, to the fullest extent permitted by any applicable portion of this Article XI that shall not have been invalidated.

TRANSFERS OF UNITS

Section 12.1 Restrictions on Transfers of Units.

(a) Generally. Except pursuant to the procedures described in this Article XII, a Member shall not, in any transaction or series of transactions, directly or indirectly, Transfer all or any of its Units. Any attempt by a Member to Transfer, directly or indirectly, all or any of its Units in violation of this Agreement shall be void ab initio and will not be an effective Transfer of such Units.

(b) No Indirect Transfer. Without limiting the generality of the foregoing, the stock, limited liability company interests, partnership interests or other equity securities of any Non-Managing Member may not be Transferred by the holders thereof, and there shall be no change of Control of any Non-Managing Member, in each case without written approval of the Managing Member, which approval may be withheld or conditioned (including upon modification of the terms of any Units) in its sole discretion.

Section 12.2 Permitted Transfers. Notwithstanding the foregoing restrictions on Transfers:

(a) The Managing Member may Transfer, without being subject to Section 12.3 (other than clause (c)(iii) thereof), all or any of its Units to an Affiliate at any time;

(b) any Member may Transfer, without being subject to Section 12.3 (other than clause (c)(iii) thereof), all or any of its Units pursuant to a pledge or security agreement in favor of the collateral agent for the secured parties under any Financing Agreement Transaction Documents; and

(c) any Non-Managing Member may Transfer, without being subject to Section 12.3 (other than clause (c)(iii) thereof), all or any of its Units with the prior written approval of the Managing Member, which approval may be withheld or conditioned (including upon modification of the terms of any Units) in its sole discretion.

29

Section 12.3 Overriding Provisions.

(a) The approval of any Transfer in any one or more instances shall not limit or waive the requirement for such approval in any other or future instance.

(b) Except as provided in Section 12.2, all Transfers permitted under this Article XII are subject to this Section 12.3, Section 12.4 and Section 12.5.

(c) Any proposed Transfer by a Member pursuant to the terms of this Article XII shall, in addition to meeting applicable requirements of this Agreement, satisfy the following conditions:

(i) the Transfer will 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 Treasury Regulations Section 1.7704-1, and, at the request of the Managing Member, the transferor and the transferee will have each provided the Company a certificate to such effect;

(ii) the proposed Transfer will not result in the Company having more than 100 Members, within the meaning of Treasury Regulations Section 1.77041(h)(1) (determined pursuant to the rules of Treasury Regulations Section 1.77041(h)(3)) or otherwise cause the Company to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code; and

(iii) the proposed Transfer will be made in accordance with all applicable laws and regulations, all necessary governmental consents shall have been obtained and requirements satisfied, including compliance with U.S. federal and state securities laws, and the Transfer will not cause the Company to breach or violate any applicable law or the terms and conditions of any Financing Agreement Transaction Documents.

The Managing Member may request an opinion of legal counsel or other evidence reasonably satisfactory to the Managing Member with respect to any of the foregoing provisions of this Section 12.3 or any other matters that the Managing Member reasonably deems appropriate in respect of any such proposed Transfer. The Managing Member may waive any of the foregoing provisions except as otherwise required by applicable law.

(d) The Members’ Capital Account balances shall promptly be amended to reflect any permitted transfers of Units pursuant to this Article XII in the manner set forth in Section 7.7.

Section 12.4 Release of Liability.

30

Section 12.5 Substitute Members.

(a) In the event a Member Transfers its Units in compliance with the applicable provisions of this Article XII, the transferee thereof shall become a Member in substitution of the transferor in respect of the Units so transferred, with all of the rights and limitations attendant to the transferor’s Units and Ownership Percentage just as if such transferee were a Member hereunder, upon satisfaction of the following:

The effective date of any Transfer permitted under this Agreement shall be the close of business on the day of receipt thereof by the Company.

Section 12.6 Resignation. No Member may resign from the Company, other than as a result of a Transfer of all of such Member’s Units effected in accordance with the terms of this Agreement.

ARTICLE XIII.

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 13.1 Dissolving Events. The Company shall be dissolved and its affairs wound up in the manner hereinafter provided upon the happening of any of the following events:

(a) the Members vote or agree in writing to dissolve the Company;

(b) any event which under applicable law would cause the dissolution of the Company; provided, that unless required by law, the Company shall not be wound up as a result of any such event and the business of the Company shall continue.

Notwithstanding the foregoing, the death, retirement, resignation, expulsion, bankruptcy or dissolution of any Member or the occurrence of any other event that terminates the continued membership of any Member in the Company under the Delaware Act shall not, in and of itself, cause the dissolution of the Company. In such event, the remaining Member(s) shall continue the business of the Company without dissolution.

31

Section 13.2 Liquidation. Upon the dissolution of the Company, unless an election to continue the Company is made pursuant to Section 13.1, the business and affairs of the Company shall be wound up, and the Managing Member (or its designee) will serve as liquidator (the “Liquidator”) of the Company.

(a) Except as expressly provided in this Article XIII, the Liquidator will have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the Managing Member and the Members under the terms of this Agreement, to the extent necessary or desirable in the good faith judgment of the Liquidator to carry out the duties and functions of the Liquidator hereunder for and during such period of time as will be required in the good faith judgment of the Liquidator to complete the winding up and liquidation of the Company as provided for herein.

(b) Except as otherwise provided in this Article XIII (including Section 13.4 below), the Liquidator will liquidate the assets of the Company and apply and distribute the net proceeds of such liquidation in the following manner and order:

(i) first, net proceeds of the liquidation will be applied and distributed to creditors in satisfaction of indebtedness (other than any loans or advances that may have been made by any of the Members to the Company), whether by payment or placing in escrow a reserve of cash or other assets of the Company for the payment of creditors, certain administrative expenses (including payment of the expenses of the terminating transactions such as brokerage commissions, legal fees, accounting fees and closing costs) and contingent liabilities in an amount reasonably determined by the Liquidator to be appropriate for such purposes; and

(ii) second, net proceeds of the liquidation will be applied to the payment of outstanding loans that may have been made by any of the Members to the Company; and

(iii) third, remaining net proceeds of the liquidation shall be distributed to Members in accordance with Section 9.1.

provided, that no payment or distribution in any of the foregoing categories shall be made until all payments in each prior category shall have been made in full; provided, further, that if the payments due to be made in any of the foregoing categories exceed the remaining proceeds available for such purpose, such payments shall be made to the Persons entitled to receive the same pro rata in accordance with the respective amounts due to them.

Section 13.3 Reserves. After all of the assets of the Company have been distributed, the Company will terminate in accordance with Section 13.5. If at any time thereafter any funds in any cash reserve fund referred to in Section 13.2(b) are released because the need for such cash reserve fund has ended, such funds will be distributed to the Members in the same manner as if such distribution had been made pursuant to Section 13.2(b).

32

Section 13.4 Distribution In Kind. Notwithstanding the provisions of Section 13.2 that require the liquidation of the assets of the Company, if, upon the dissolution of the Company, the Liquidator determines that an immediate sale of part or all of the Company’s assets would be impractical or would cause undue loss to the Members, the Liquidator may, in good faith, defer for a time the liquidation of any assets except those necessary to satisfy liabilities of the Company (other than the Company’s liabilities to its Members). The Liquidator may distribute to the Members, in lieu of cash, such Company assets as the Liquidator deems not suitable for liquidation. Any distributions in kind will be subject to such conditions relating to the disposition and management thereof as the Liquidator reasonably deems equitable. Furthermore, to the extent that there is a distribution of Company property pursuant to Section 13.2 in accordance with this Section 13.4, the ratio of cash to non-cash distributions shall be identical for each Member, unless any Member elects, in its sole discretion, to take a greater portion of its distribution in non-cash Company property. The Liquidator will value any property distributed in kind based upon such property’s fair market value as determined using such method of valuation as the Liquidator and the Members receiving any such in-kind distribution agree upon.

Section 13.5 Termination. The Company shall terminate when the winding up of the Company’s affairs has been completed, all of the assets of the Company have been distributed and the Certificate has been canceled, all in accordance with the Delaware Act.

Section 13.6 Claims of the Members. The Members and former Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members and former Members shall have no recourse against the Company or any other Member.
