(i) To the extent permitted by applicable law and subject to the provisions of this Agreement (including Section 1.9(c)(ii) and Article V), in furtherance of the purposes of the Company set forth in Section 1.3, the Managing Member is hereby authorized to cause the Company to purchase property (whether real, personal, or mixed) from, sell Property to or otherwise deal with any Member, acting on its own behalf, or any Affiliate of any Member (each such agreement, a “Related Party Transaction”); provided that any such purchase, sale, or other transaction shall be made on terms and conditions which are no less favorable to the Company than those generally being provided to or available from an independent third party.

(ii) Any transaction or series of related transactions that is a Related Party Transaction between the Managing Member (or an Affiliate) and the Company that involves aggregate payments in excess of $250,000, other than reimbursements to the Managing Member for Reimbursable Company Expenses incurred in connection with the Company’s business pursuant to Section 5.3(b), which will be reported in accordance with Section 5.3(c) (each such transaction, an “Above Threshold Related Party Transaction”), must have the prior approval of a majority of the Company Conflicts Committee (as defined in Section 1.9(c)(iii) below).

(iii) The Class A Member and the Managing Member shall each designate two (2) members to serve on a committee (the “Company Conflicts Committee”) whose purpose is to act upon any Above Threshold Related Party Transaction submitted to the Company Conflicts Committee pursuant to this Section 1.9(c)(iii). Meetings of the Company Conflicts Committee may be called by the Managing Member on not less than two (2) business days’ notice to each of the members of the Company Conflicts Committee by telephone, facsimile, mail, electronic mail, telegram or other means of communication, with such notice to specify the relevant Above Threshold Related Party Transaction for consideration at such meeting.

(iv) Unless three of the four members of the Company Conflicts Committee vote to approve any proposed Above Threshold Related Party Transaction, the Conflicts Committee members designated by the Class A Member (the “Class A Member Conflict Committee Members”) disputing the fairness of the Above Threshold Related Party Transaction are required to submit a good faith proposal of terms and conditions with respect to such Above Threshold Related Party Transaction that they reasonably believe to be no less favorable to the Company than those generally being provided to or available from an independent third party.

(v) If the Class A Conflict Committee Members and the two members of the Company Conflicts Committee designated by the Managing Member (the “Managing Member Conflict Committee Members”) are unable to resolve any dispute with respect to approval of an Above Threshold Related Party Transaction through good faith negotiation, then, within two (2) Business Days after such meeting, either the Class A Member or the Managing Member (either such person, the “Initiating Party”‘) may submit the Above Threshold Related Party Transaction Dispute to arbitration in accordance with the following paragraphs (1)-(4).

(1) Location of Arbitration: Procedures. Any Initiating Party may cause the filing (such filing, an “Arbitration Filing”) in Houston, Texas or such other place as may be mutually acceptable to the Class A Member and the Managing Member under the AAA Commercial Arbitration Rules with Expedited Procedures in effect on the date hereof, as modified by Section 1.9(c)(v)(1)-(4).

(2) Selection of Arbitrator. The Class A Member and the Managing Member shall meet within two (2) Business Days after the date of any dispute to agree upon a neutral arbitrator with at least fifteen (15) years experience in a senior management capacity in the operation of natural gas pipelines and processing plants to resolve the dispute. If the Class A Member and the Managing Member are unable to agree upon a neutral arbitrator within two (2) Business Days of such meeting, then the AAA shall select from its Large Complex Case Panel one neutral arbitrator with at least fifteen (15) years experience in a senior management capacity in the operation of natural gas pipelines and processing plants.

(3) Submissions. The Initiating Party shall submit to the arbitrator the dispute to be decided and set forth matters with respect to the dispute as the Initiating Party deems appropriate. Within five (5) days thereafter, the other Person (such other person, the “Responding Party”) shall submit to the arbitrator its response to the Arbitration Filing and set forth matters with respect to the dispute as the Responding Party deems appropriate. The arbitrator shall determine (a) whether an experienced and prudent operator of natural gas pipelines and processing plants would consider the terms and conditions of the transaction leading to the dispute to be no less favorable to the Company than those generally being provided to or available from an independent third party, and (b) if not, the terms and conditions that would generally be provided to or available from an independent third party. The arbitrator’s decision on one or both of these issues shall be set forth in writing.

(4) Effect of Determination: Costs. The determination(s) by the arbitrator described in Article 1.9(c)(v)(3) above shall be final and binding upon the Company Conflicts Committee. The cost of the arbitration (including fees of the AAA and the arbitrator) shall be borne equally by the Class A Member and the Managing Member.

(vi) On or before the 60^th day following the end of each quarter, the Managing Member shall furnish the Company Conflicts Committee a schedule of any transaction or series of related transactions entered into during such preceding quarter that constitute a Related Party Transaction by the Company with the Managing Member or an Affiliate involving aggregate payments of less than $250,000, other than reimbursements to the Managing Member for Reimbursable Company Expenses incurred in connection with the Company’s business pursuant to Section 5.3(b), which will be reported in accordance with Section 5.3(c) (each such transaction, a “Below Threshold Related Party Transaction”). Any Class A Member Conflicts Committee Member may, within seventy-five (75) days following actual receipt by such Class A Conflicts Committee Member of the schedule provided pursuant to this Section 1.9(c)(vi), dispute in writing any amount set forth on the schedule with respect to any Below Threshold Related Party Transaction on the ground that such amount was not fair and reasonable to the Company. The Managing Member and the Class A Member Conflicts Committee Members shall attempt to resolve such dispute, acting diligently and in good faith. If the Managing Member and the Class A Member Conflicts Committee Members are unable to resolve any such dispute within thirty (30) days, or such additional time as may be reasonable under the circumstances, either the Managing Member or any Class A Member Conflicts Committee Member may submit the dispute to arbitration in accordance with paragraphs (1)-(4) of Section 1.9(c)(v).

(d) In accordance with the provisions of Section 18-1101 of the Delaware Limited Liability Company Act, to the extent that, at law or in equity, a Member of the Company has duties (including fiduciary duties) to the Company or to another Member or to another Person that is a party to or is otherwise bound by this Agreement, all such duties (including fiduciary duties) of any such Member are hereby waived and eliminated; provided, that the foregoing provision shall only be given effect to the fullest extent permitted by applicable law and shall not eliminate or waive the implied contractual covenant of good faith and fair dealing.

Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2).

(b) Member Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Article III, if there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any Allocation Year, each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in an amount equal to such Member’s share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4).

(d) Gross Income Allocation. In the event that any Member has an Adjusted Capital Account Deficit at the end of any Allocation Year, each such Member shall be allocated items of Company income and gain in the amount of such deficit as quickly as possible; provided that an allocation pursuant to this Section 3.3(d) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit in excess of such sum after all other allocations provided for in this Article III have been tentatively made as if Section 3.3(c) and this Section 3.3(d) were not in this Agreement.

(e) Nonrecourse Deductions. Nonrecourse Deductions for any Allocation Year shall be allocated 95% to the Managing Member and 5% to the Class A Member.

3.4

Regulatory Allocations.

The allocations set forth in Sections 3.3(a), 3.3(b), 3.3(c), 3.3(d), 3.3(e), 3.3(f) and 3.3(g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Members that, to the extent possible, the Regulatory Allocations shall be offset with special allocations of other items of Company income, gain, loss, or deduction pursuant to this Section 3.4. Therefore, notwithstanding any other provision of this Article III (other than the Regulatory Allocations), the Tax Matters Member shall, with the consent of the Class A Member, which consent will not be unreasonably withheld, delayed or conditioned, 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 and all Company items were allocated pursuant to Section 3.1, Section 3.2, and Section 3.3 (other than the Regulatory Allocations). In exercising its discretion under this Section 3.4, the Tax Matters Member shall take into account future Regulatory Allocations under Sections 3.3(a) and 3.3(b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 3.3(e) and 3.3(f).

3.5

Other Allocation Rules.

(a) Profits, Losses, and any other items of income, gain, loss, or deduction will be allocated to the Members pursuant to this Article III as of the last day of each Fiscal Year; provided that Profits, Losses, and such other items shall also be allocated at such times as the Gross Asset Values of Property are adjusted pursuant to subparagraph (ii) of the definition of “Gross Asset Value” in Section 1.10.

(b) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily, monthly, or other basis, as determined by the Tax Matters Member (except to the extent otherwise provided in Section 10.7) using any permissible method under Code Section 706 and the Regulations thereunder.

(c) The Members are aware of the income tax consequences of the allocations made by this Article III and hereby agree to be bound by the provisions of this Article III in reporting their shares of Company income and loss for income tax purposes, except as otherwise required by law.

3.6

Tax Allocations; Code Section 704(c).

(a) Except as otherwise provided in this Section 3.6, 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 this Article III.

(b) In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and deduction with respect to any Property contributed to the capital of the Company 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 for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of Gross Asset Value) using the “remedial allocation method” described in Treasury Regulations Section 1.704-3(d). For purposes of applying Section 704(c) and the remedial allocation method, to the extent that the Company is required under Code Section 263A to capitalize into inventory costs depreciation allowances with respect to the Anadarko Contributed Assets, the difference between gross income derived from the business of operating the Anadarko Contributed Assets as computed for Code Section 704(b) purposes and gross income derived from the business of operating the Anadarko Contributed Assets as computed for tax purposes will be treated as gain from the disposition of a contributed asset.

(c) In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder applying the “remedial allocation method” described in Treasury Regulations Section 1.704-3(d).

(d) Any elections or other decisions relating to such allocations shall be made by the Tax Matters Member, with the consent of the Class A Member, which consent will not be unreasonably withheld, delayed or conditioned, in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 3.6 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

ARTICLE IV

(a) Cash Available for Distribution.

First, 99% to the Class A Member and 1% to the Managing Member until the Class A Member has been distributed an amount equal to the excess, if any, of (A) its cumulative Class A Member Priority Return from the Closing Date through such Distribution Date, over (B) all prior distributions to the Class A Member pursuant to this Section 4.1(a)(i);

(c) Special Distributions of Interests in the APC Note. The Company shall, upon a written request of the Class A Member given to the Managing Member within five (5) Business Days of any distribution of Cash From Sales made pursuant to Section 4.1(b), distribute a portion of the APC Note with a ▇▇▇▇-to-Market Value equal to ninety percent (90%) of the Gross Asset Value of the Anadarko Contributed Assets with respect to which such distribution under Section 4.1(b) was made.

(d) APC Note Prepayments. The Company shall distribute 100% of all APC Note Prepayments to the Managing Member within ten (10) Business Days following the Company’s receipt thereof.

The variance between the

estimated Cash Available for Distribution and the actual Cash Available for Distribution for such quarter (the “Cash Available for Distribution Variance”) shall increase or decrease, as applicable, the amount of Cash Available for Distribution for the next quarter.

4.2

Amounts Withheld.

All amounts withheld pursuant to the Code or any provision of any state, local, or foreign tax law with respect to any payment, distribution, or allocation to the Company or the Members will be treated as amounts paid or distributed, as the case may be, to the Members with respect to which such amount was withheld pursuant to this Section 4.2 for all purposes under this Agreement. The Company is authorized to withhold from payments and distributions, or with respect to allocations, to the Members, and to pay over to any federal, state, and local government or any foreign government, any amounts required to be so withheld pursuant to the Code or any provisions of any other federal, state, or local law or any foreign law, and will allocate any such amounts to the Members with respect to which such amount was withheld.

4.3

Limitations on Distributions.

The Company shall make no distributions to the Members except (i) as provided in this Article IV and Section 10.8 and Article XII, or (ii) as agreed to by all of the Members.

4.4

Distributions and Payments to Members.

It is the intent of the Members that no distribution or payment to any Member (including distributions under Sections 4.1, 10.8 and 12.2) will be deemed a return of money or other property in violation of the Act. The payment or distribution of any such money or property to a Member will be deemed to be a compromise within the meaning of Section 18-502(b) of the Act, and the Member receiving any such money or property will not be required to return any such money or property to the Company, any creditor of the Company or any other Person. However, if any court of competent jurisdiction relating to such Member holds pursuant to a final, nonappealable judgment that, notwithstanding the provisions of this Agreement, any Member is obligated to return such money or property, such obligation will be the obligation of such Member. The Members agree that in no event will the obligation of any Member to return such money or property be the obligation of the Company or any other Member irrespective of whether or not such obligation arises out of a final, nonappealable judgment of a court of competent jurisdiction. Any amounts required to be paid under such obligation will be treated as a permitted Additional Capital Contribution pursuant to Section 2.2.

The Class A Member shall bear all expenses of its own participation in any audit or subsequent controversy involving a Special Class A Issue.

The Members will execute any forms necessary to effectuate the TEFRA Election.

(d) Tax Returns and Tax Information. The Tax Matters Member shall prepare (in consultation with and subject to the prior written approval of the Class A Member, which shall not be unreasonably withheld, delayed or conditioned) and file all necessary federal, state and local income and franchise tax returns (including all notices, disclosures, registrations, information statements, etc., required in connection therewith) for the Company, shall make any and all elections allowed or required for federal and state income tax purposes including, without limitation, the election to adjust the tax basis of properties owned by the Company pursuant to Section 754 of the Code and shall prepare and file all other tax returns for the Company. Returns and other reports referred to in this Section 8.3(d) shall be prepared, where applicable, in accordance with the Code and Regulations. The Tax Matters Member shall file the Company’s federal income tax return for each calendar year on or before the due date, including extensions thereof. The Tax Matters Member shall provide to each Member on a timely basis (but no later than 30 days after the end of each of the first three quarters in each calendar year and by April 15

following the end of each calendar year), a year-to-date estimate of all income, gains, losses, deductions, credits, depletion and gain or loss for the Company (the “Tax Return Items”). The Tax Matters Member agrees that it will, upon the request of any Member, cooperate with that Member or its tax advisors upon reasonable notice with regard to the timely compilation of the information pertaining to that Member’s estimated income tax liability under the Code. The Tax Matters Member shall be responsible for the maintenance of all tax accounting records, including depreciation, cost recovery and amortization records, and shall provide a copy of such records to any Member upon request. The Tax Matters Member shall deliver to the Members copies of the federal, state and local income and franchise tax returns and the Tax Return Items for all calendar years on or before June 15 following the end of each such year.

(e) Partner Level Audits. Each Member shall retain complete control with respect to any IRS audit of such Member (as opposed to the Company) and of any contest resulting therefrom, but if an issue is raised in any such audit of a Member that relates to the Company or to any Special Class A Issue, the affected Member shall keep the other Members reasonably informed of the progress of any such issue (including providing copies of any written communications with the IRS on such issue, suitably redacted to remove references to unrelated matters).

(f) Cooperation of Class A Member. The Class A Member shall provide to the Tax Matters Member such information as is reasonably required to allow the Tax Matters Member to perform its obligations under this Section 8.3.

(g) Timely Tax Compliance; Replacement of Tax Matters Member. The Tax Matters Member will perform its obligations under this Section 8.3 in a timely manner, including but not limited to meeting any applicable federal, state or local tax filing deadlines, or obtaining extensions of such deadlines from the relevant taxing authority. In the event that the Tax Matters Member fails to perform its obligations under this Section 8.3 in a timely manner (and to the extent that such failure could reasonably be expected to cause a material adverse impact on the Class A Member) and the Class A Member has complied with its obligations under Section 8.3(f), the Class A Member may replace the Tax Matters Member by delivering to the Tax Matters Member a notice of such election and upon delivery of such notice, the Class A Member will become the successor Tax Matters Member; provided, however, that the Managing Member will have the right to review (i) all prospective tax returns prior to filing and (ii) any written communications received from the IRS by the successor Tax Matters Member, and the Managing Member may provide comments to the successor Tax Matters Member with respect to these items, which the successor Tax Matters Member may take into consideration.

(c) Such Transfer will not cause the Company to be deemed to be an “investment company” under the Investment Company Act of 1940, as amended and the transferor shall provide an opinion of nationally recognized counsel to such effect. The Managing Member and the other Members shall provide to such counsel any information available to the Managing Member or to such other Members, as the case may be, and relevant to such opinion.

10.4

Prohibited Transfers.

Any purported Transfer of an Interest that is not a Permitted Transfer shall, to the fullest extent permitted by law, be null and void and of no force or effect whatsoever; provided that, if the Company is required to recognize a Transfer that is not a Permitted Transfer, the rights with respect to the Transferred Interest shall be strictly limited to the transferor’s rights to allocations and distributions as provided by this Agreement with respect to the Transferred Interest, which allocations and distributions may be applied (without limiting any other legal or equitable rights of the Company) to satisfy any debts, obligations, or Liabilities for damages that the transferor or transferee of such Interest may have to the Company.

In the case of a Transfer or attempted Transfer of an Interest that is not a Permitted Transfer, the parties engaging or attempting to engage in such Transfer shall be liable to indemnify and hold harmless the Company and the other Members from all Liability and Damages that the Company or any of such indemnified Members may incur (including incremental tax liabilities, lawyers’ fees and expenses) as a result of such Transfer or attempted Transfer and efforts to enforce the indemnity granted hereby.

10.5

Rights of Unadmitted Assignees.

A Person who acquires an Interest but who is not admitted as a substituted Member pursuant to Section 10.6 shall be entitled only to allocations and distributions with respect to such Interest in accordance with this Agreement, and, to the fullest extent permitted by law, shall have no right to any information or accounting of the affairs of the Company, shall not be entitled to inspect the books or records of the Company, and shall not have any of the rights of a Member under the Act or this Agreement.

10.6

Admission of Substituted Members.

Subject to the other provisions of this Article X, a transferee of an Interest may be admitted to the Company as a substituted Member only upon satisfaction of the conditions set forth in this Section 10.6:

(a) The Interest with respect to which the transferee is being admitted was acquired by means of a Permitted Transfer;

(b) The transferee of an Interest (other than, with respect to clauses (i) and (ii) below, a transferee that was a Member prior to the Transfer) shall, by written instrument, (i) accept and adopt the terms and provisions of this Agreement, including this Article X, and (ii) assume the obligations of the transferor Member under this Agreement with respect to the Transferred Interest. The transferor Member shall be released from all such assumed obligations except (x) those obligations or Liabilities of the transferor Member arising out of a breach of this Agreement by the transferor Member and (y) in the case of a Transfer to any Person other than a Member, those obligations or Liabilities of the transferor Member based on events occurring, arising, or maturing prior to the date of Transfer; and

(c) The transferee and transferor shall each execute and deliver such other instruments as the Managing Member reasonably deems necessary or appropriate to effect, and as a condition to, such Transfer, including amendments to the Certificate or any other instrument filed with the State of Delaware or any other state or Governmental Authority.

10.7

Distributions and Allocations in Respect of Transferred Member Interests.

If any Interest is Transferred during any Allocation Year in compliance with the provisions of this Article X, Profits, Losses, each item thereof, and all other items attributable to the Transferred Interest for such Allocation Year shall be divided and allocated between the transferor and the transferee by taking into account their varying Interests during the Fiscal Year in accordance with Code Section 706(d), using any conventions permitted by law and agreed to by the transferor and transferee. All distributions on or before the date of such Transfer shall be made to the transferor, and all distributions thereafter shall be made to the transferee. Solely for purposes of making such allocations and distributions, the Company shall recognize such Transfer not later than the end of the calendar month during which it is given notice of such Transfer; provided that, if the Company is given notice of a Transfer at least ten (10) Business Days prior to the Transfer, the Company shall recognize such Transfer as of the date of such Transfer; and provided further that if the Company does not receive a notice stating the date such Interest was Transferred and such other information as the Managing Member may reasonably require within thirty (30) days after the end of the Allocation Year during which the Transfer occurs, then all such items shall be allocated, and all distributions shall be made, to the Person who, according to the books and records of the Company, was the owner of the Interest on the last day of such Allocation Year. To the fullest extent permitted by law, neither the Company nor the Managing Member shall incur any Liability for making allocations and distributions in accordance with the provisions of this Section 10.7, whether or not the Managing Member or the Company has knowledge of any Transfer of ownership of any Interest.

10.8

Redemption of Class A Member’s Interest in the Company.

(a) The Class A Member’s entire Interest is required to be redeemed by the Company (a “Mandatory Redemption”) on the 30th anniversary of the Closing Date (or the next Business Day if such date does not fall on a Business Day). In addition, the Class A Member may, by delivery of a written notice to the Managing Member (a “Class A Member Redemption Notice”) at any time after the 15th anniversary of the Closing Date, elect to cause the Company to redeem on the last Business Day of any Fiscal Quarter, all (but not less than all) of the Class A Member’s Interest. Finally, the Managing Member may, by delivery of a written notice to the Class A Member (a “Managing Member Redemption Notice” and, together with a Class A Member Redemption Notice, a “Redemption Notice”) prior to the effectiveness of any Liquidation Notice delivered to the Managing Member pursuant to Section 13.2, or at any time after the 15th anniversary of the Closing Date, elect pursuant to a redemption option (the “Redemption Option”) to have the Company redeem all of the Class A Member’s Interest.

(b) In the event that the Class A Member’s Interest in the Company is redeemed pursuant to this Section 10.8, (i) the ▇▇▇▇-to-Market Value of the Property shall be determined in accordance with Section 13.3 hereof and the Gross Asset Values of all the Property shall be adjusted pursuant to subparagraph (ii) of the definition of “Gross Asset Value” in Section 1.10 as of the Valuation Date, and the Gross Liability Values of the Liabilities of the Company shall be adjusted pursuant to the definition of “Gross Liability Value” in Section 1.10 as of the Redemption Date, and (ii) Profits, Losses, and other items of Company income, gain, loss, or deduction for the period beginning on the first day of the Allocation Year during which the Redemption Date occurs and ending on the Redemption Date shall be allocated pursuant to Article III. On the Redemption Date, if permitted by the Act and other applicable law, the Company shall distribute to the Class A Member an amount of Cash or other property the aggregate Gross Asset Values of which are equal to the balance in the Class A Member’s Capital Account immediately after giving effect to the adjustments and allocations required by the first sentence of this Section 10.8(b); provided that, unless the Managing Member and the Class A Member otherwise consent, the APC Note shall be distributed to the Class A Member in redemption of the Class A Member’s Interest. If the Capital Account balance of the Class A Member exceeds the Gross Asset Value of the APC Note, the Company shall also distribute cash in an amount equal to such excess as part of the redemption distribution. If the Gross Asset Value of the APC Note exceeds such Capital Account balance, the Class A Member will be required to contribute cash equal to such excess to the Company.

(c) In the event that the Class A Member’s Interest in the Company is being redeemed pursuant to Section 10.8(a), distributions shall be made to such Member, and its Interest in the Company shall be retired, at 9:00 a.m. on (the “Redemption Date”) (i) in the case of a Mandatory Redemption, the 30th anniversary of the Closing Date (or the next Business Day if such date does not fall on a Business Day), or (ii) in the case of any other redemption, the date

that is specified in the Redemption Notice, which date shall not be less than five (5) Business Days or more than fifteen (15) Business Days after the date on which the Redemption Notice was given pursuant to Section 10.8(a).

POWER OF ATTORNEY

11.1

Managing Member as Attorney In Fact.

Each Member hereby makes, constitutes, and appoints the Managing Member, each successor Managing Member, and the Liquidator, severally, with full power of substitution and resubstitution, its true and lawful attorney in fact for it and in its name, place, and stead and for its use and benefit, to sign, execute, certify, acknowledge, swear to, file, publish, and record (i) all certificates of formation, amended name or similar certificates, and other certificates and instruments (including counterparts of this Agreement) that the Managing Member or Liquidator may deem necessary to be filed by the Company under the laws of the State of Delaware or any other jurisdiction in which the Company is doing or intends to do business; provided that such power does not extend to the signing or execution of counterparts of this Agreement on behalf of the Class A Member; (ii) any and all amendments, restatements, or changes to this Agreement and the instruments described in clause (i), as now or hereafter amended, which the Managing Member may deem necessary to effect a change or modification of the Company in accordance with the terms of this Agreement, including amendments, restatements, or changes to reflect (A) the exercise by the Managing Member of any power granted to it under this Agreement, (B) the admission of any additional or substituted Member, and (C) the disposition by any Member of its Interest; provided that the Managing Member shall not, to the extent that any amendment, modification, or change to this Agreement requires the consent of the Class A Member, execute such amendment on behalf of the Class A Member without the express written consent of the Class A Member; (iii) all certificates of cancellation and other instruments which the Liquidator deems necessary or appropriate to effect the dissolution and termination of the Company pursuant to the terms of this Agreement, and (iv) any other instrument which is now or may hereafter be required by law to be filed on behalf of the Company or is deemed necessary by the Managing Member, or Liquidator to carry out fully the provisions of this Agreement in accordance with its terms.

11.2

Nature of Special Power.

The power of attorney granted pursuant to this Article XI:

(a) Is a special power of attorney coupled with an interest and is irrevocable; provided, however, that, with respect to the power of attorney granted to the Managing Member, such power shall terminate upon the appointment of the Liquidator;

(b) Subject to Section 11.1(ii) hereof, may be exercised by such attorney in fact by listing the Members executing any agreement, certificate, instrument, or other document with the single signature of any such attorney in fact acting as attorney in fact for such Members; and

(c) Shall survive and not be affected by the subsequent Bankruptcy, insolvency, dissolution, or cessation of existence of a Member and shall survive the delivery of an assignment by a Member of the whole or a portion of its Interest (except that where the assignment is of such Member’s entire Interest and the assignee, with the consent of the other Members, is admitted as a substituted Member, the power of attorney shall survive the delivery of such assignment for the sole purpose of enabling any such attorney in fact to effect such substitution) and shall extend to such Member’s or assignee’s successors and assigns.

ARTICLE XII

DISSOLUTION AND WINDING UP

12.1

Liquidating Events.

(a) Liquidation. The Company shall dissolve and shall commence winding up and liquidating upon the first to occur of any of the following (each a “Liquidating Event”):

(i)

The date upon which a Liquidation Notice becomes effective to cause a Notice Event to become a Liquidating Event;

(ii)

The Bankruptcy of any of the Company or any Member;

(iii)

The unanimous vote of the Members to dissolve, wind up, and liquidate the Company;

(iv)

The happening of any other event which the Managing Member determines in good faith and upon advice of counsel to the Company makes it unlawful, impossible, or impractical to carry on the business of the Company;

(v)

The failure of the Managing Member to cause the Company to redeem the Class A Member’s Interest in accordance with Section 10.8;

(vi)

The entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act; or

(vii)

At any time there are no members of the Company unless the Company is continued in accordance with the Act.

The Members hereby agree that, notwithstanding any provision of the Act, the Company shall not dissolve prior to the occurrence of a Liquidating Event.

(b) Reconstitution. If it is determined, by a court of competent jurisdiction, that the Company has dissolved prior to the occurrence of a Liquidating Event, then within an additional ninety (90) days after such determination (the “Reconstitution Period”), all of the Members may elect to reconstitute the Company and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited liability company on terms identical to those set forth in this Agreement. Unless such an election is made within the Reconstitution Period, the Company shall wind up its affairs in accordance with Section 12.2. If such an election is made within the Reconstitution Period, then:

(i)

The reconstituted limited liability company shall continue until the occurrence of a Liquidating Event as provided in Section 12.1(a);

(ii)

Unless otherwise agreed to by all of the Members, the Certificate and this Agreement shall, subject to any requirement under the Act to file a new certificate of formation, automatically constitute the Certificate and Agreement of such new Company. All of the assets and liabilities of the dissolved Company shall be deemed to have been automatically assigned, assumed, conveyed, and transferred to the new Company. No bond, collateral, assumption, or release of any Member’s or the Company’s liabilities shall be required;

provided that the right of the Members to select successor managers and to reconstitute and continue the business of the Company shall not exist and may not be exercised unless the Company has received an opinion of counsel that the exercise of the right would not result in the loss of limited liability of any Member and neither the Company nor the reconstituted limited liability company would cease to be treated as a partnership for federal income tax purposes upon the exercise of such right to continue.

12.2

Winding Up.

Upon the occurrence of (i) a Liquidating Event or (ii) the determination by a court of competent jurisdiction that the Company has dissolved prior to the occurrence of a Liquidating Event (unless the Company is reconstituted pursuant to Section 12.1(b) hereof), the Company shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Members, and no Member shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Company’s business and affairs; provided that, to the extent not inconsistent with the foregoing, all covenants contained in this Agreement and obligations provided for in this Agreement shall

continue to be fully binding upon the Members until such time as the Property has been distributed pursuant to this Section 12.2 and the Certificate has been canceled pursuant to the Act. The Liquidator shall be responsible for overseeing the winding up of the Company, which winding up shall be completed within ninety (90) days of the occurrence of the Liquidating Event and within ninety (90) days after the last day on which the Company may be reconstituted pursuant to Section 12.1(b) hereof. The Liquidator shall take full account of the Company’s liabilities and Property and shall cause the Property or the proceeds from the sale thereof (as determined pursuant to Section 12.9 hereof), to the extent sufficient therefor, to be applied and distributed, to the maximum extent permitted by law, in the following order:

(c) Third, to Members and former Members of the Company in satisfaction of liabilities for distribution under Sections 18-601 or 18-604 of the Act; and

(d) The balance, if any, to the Members in accordance with the positive balance in their Capital Accounts, computed in accordance with Section 8.2(e) and after giving effect to all contributions, distributions, and allocations for all periods.

No Member shall receive additional compensation for any services performed pursuant to this Article XII.

12.3

Compliance With Certain Requirements of Regulations; Deficit Capital Accounts.

In the event the Company is “liquidated” within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant to this Article XII to the Members who have positive Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2). If any Member has a deficit balance in its Capital Account (after giving effect to all contributions, distributions, and allocations for all Allocation Years, including the Allocation Year during which such liquidation occurs), such Member shall have no obligation to make any contribution to the capital of the Company with respect to such deficit, and such deficit shall not be considered a debt owed to the Company or to any other Person for any purpose whatsoever. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Members pursuant to this Article XII may be:

(a) Distributed to a trust established for the benefit of the Members for the purposes of liquidating Company assets, collecting amounts owed to the Company, and paying any contingent or unforeseen liabilities or obligations of the Company. The assets of any such trust shall be distributed to the Members from time to time, in the reasonable discretion of the Liquidator, in the same proportions as the amount distributed to such trust by the Company would otherwise have been distributed to the Members pursuant to Section 12.2; or

(b) Withheld to provide a reasonable reserve for Company liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Company; provided that such withheld amounts shall be distributed to the Members as soon as practicable.

12.4

Deemed Distribution and Recontribution.

Notwithstanding any other provision of this Article XII, in the event the Company is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Property shall not be liquidated, the Company’s Debts and other 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 its Property and Liabilities to a new limited liability company in exchange for an interest in such new company and, immediately thereafter, the Company will be deemed to liquidate by distributing interests in the new company to the Members.

12.5

Rights of Members.

Except as otherwise provided in this Agreement or the Master Offset Agreement, each Member shall look solely to the Property for the return of its Capital Contributions and has no right or power to demand or receive Property other than cash from the Company. If the assets of the Company remaining after payment or discharge of the Debts or Liabilities of the Company are insufficient to return such Capital Contributions, the Members shall have no recourse against the Company, the Managing Member or any other Member.

12.6

Allocations and Distributions During Period of Liquidation.

During the period commencing on the first day of the Fiscal Year during which a Liquidating Event occurs and ending on the date on which all of the assets of the Company have been distributed to the Members pursuant to Section 12.2 hereof, the Members shall continue to share Profits, Losses, gain, loss, and other items of Company income, gain, loss, or deduction in the manner provided in Article III but no distributions shall be made pursuant to Article IV after the day on which the Liquidating Event occurs.

12.7

Character of Liquidating Distributions.

All payments made in liquidation of the Interest of a Member in the Company shall be made in exchange for the Interest of such Member in Property pursuant to Section 736(b)(1) of the Code, including the interest of such Member in Company goodwill.

12.8

The Liquidator.

(a) Definition. The “Liquidator” shall be appointed by Managing Member (except that if a Liquidation Event described in Section 12.1(a)(i), Section 12.1(a)(ii) (in respect of the Bankruptcy of the Managing Member) or Section 12.1(a)(v) has occurred, the “Liquidator” shall be appointed by the Class A Member) and shall have the power of attorney granted to the Managing Member pursuant to Article XI.

(b) Compensation. The Company is authorized to pay such reasonable compensation to the Liquidator for its services performed pursuant to this Article XII as shall be agreed upon by the Liquidator and the Managing Member, or, if a Liquidation Event described in Section 12.1(a)(i), Section 12.1(a)(ii) (in respect of the Bankruptcy of the Managing Member) or Section 12.1(a)(v) has occurred, the Class A Member, to reimburse the Liquidator for its reasonable costs and expenses incurred in performing those services.

(c) Indemnification. The Company shall, to the fullest extent permitted by law, indemnify, save harmless, and pay all judgments and claims against the Liquidator or any officers, directors, stockholders, agents, or employees of the Liquidator relating to any Liability or damage incurred by reason of any act performed or omitted to be performed by the Liquidator, or any officers, directors, agents, or employees of the Liquidator in connection with the winding up of the Company, including reasonable attorneys’ fees incurred by the Liquidator, officer, director, agent, or employee in connection with the defense of any action based on any such act or omission, which attorneys’ fees may be paid as incurred, except to the extent such Liability or damage is caused by the fraud, intentional misconduct of, or a knowing violation of the laws by the Liquidator which was material to the cause of action.

12.9

Form of Liquidating Distributions.

Except as provided in this Section 12.9, for purposes of making distributions required by Section 12.2, the Liquidator may determine whether to distribute all or any portion of the Property in kind or to sell all or any portion of the Property and distribute the proceeds therefrom; provided that, if permitted by the Act and other applicable law and unless the Class A Member and the Managing Member otherwise consent, the APC Note shall be distributed to the Class A Member in liquidation of the Class A Member’s Interest. If the Capital Account balance of the Class A Member exceeds the Gross Asset Value of the APC Note, the Company shall also distribute cash in an amount equal to such excess as part of the liquidation distribution. The Liquidator shall not distribute Property other than cash to a Class A Member without its consent, and the Liquidator shall be required to reduce the Property to cash to the extent necessary to

make distributions to a Class A Member pursuant to Section 12.2 in cash. If the Gross Asset Value of the APC Note exceeds such Capital Account balance, the Class A Member will be required to contribute cash equal to such excess to the Company.

ARTICLE XIII

NOTICE EVENTS

13.1

Notice Events.

In the event that any of the following events (“Notice Events”) shall occur, the Members shall have the rights described in Section 13.2:

(a) The Managing Member fails to (i) be in substantial compliance with its obligation to deal with the Company on an arm’s length basis and as a separate entity or (ii) perform or observe any material term, covenant, or agreement, on its part to be performed or observed (other than such terms, covenants, or obligations as are described in (i) above) under this Agreement, but only if such failure continues unabated for twenty (20) days following the Managing Member obtaining notice from the Class A Member of such failure; or

(b) Any representation or warranty made or deemed made by the Managing Member under or in connection with this Agreement shall prove to have been incorrect in any material respect when made.

13.2

Liquidation Notice.

At any time on or after the occurrence of a Notice Event, the Class A Member may elect to cause such Notice Event to result in a Liquidating Event by delivering to the Managing Member a notice (a “Liquidation Notice”) of such election; provided that: (i) such Notice Event shall not result in a Liquidating Event until the expiration of three (3) Business Days following such delivery, (ii) the Class A Member may rescind such Liquidation Notice by delivering to the Managing Member a notice prior to such third (3rd) Business Day, and (iii) a Liquidation Notice automatically will be deemed rescinded upon the election within such three (3) Business Day period by the Managing Member (or its designee) pursuant to the Managing Member Redemption Option to redeem all of the Class A Member’s Interest pursuant to Section 10.8.

13.3

Determination of Gross Asset Value.

For purposes of determining the amount of any adjustment to (i) the Gross Asset Value of any Property of the Company (including the APC Note) pursuant to subparagraph (ii) or (iii) of the definition of Gross Asset Value in Section 1.10, and (ii) the Gross Liability Value of any Company Liability pursuant to the definition of Gross Liability Value in Section 1.10, the value of such Property or Company Liability will be determined in accordance with this Section 13.3 (such value being the “▇▇▇▇-to-Market Value”).

(a) In the case of any Property of the Company for which a Gross Asset Value is required by this Agreement to be determined, the Managing Member and the Class A Member shall negotiate in good faith the ▇▇▇▇-to-Market Value of the Property taking into consideration the realizable gross fair market value of the applicable Property on sale thereof to a willing, unrelated purchaser in an arms length transaction (taking into consideration any liquidity or other appropriate discounts). If the Managing Member and the Class A Member are unable to agree on the ▇▇▇▇-to-Market Value of the applicable Property, the ▇▇▇▇-to-Market Value will be determined as provided in (i)-(iv) below.

(i) The Managing Member and the Class A Member will each engage a nationally recognized independent investment banking firm (the “Managing Member Appraiser” and the “Class A Member Appraiser,” respectively) to determine the ▇▇▇▇-to-Market Value of the applicable Property using customary investment banking valuation techniques used to determine fair market value of similarly situated assets (the “Appraised Asset Value”). The Managing Member Appraiser and the Class A Member Appraiser will select a third nationally recognized independent investment banking firm not affiliated with any Member (together with the Managing Member Appraiser and the Class A Member Appraiser, the “Appraisers”) to determine the Appraised Asset Value. In the event the Managing Member Appraiser and the Class A Member Appraiser cannot agree upon the identity of the third Appraiser, the Managing Member Appraiser and the Class A Member Appraiser shall each provide a written list of three other nationally recognized independent investment banking firms, listed in alphabetical order, and the first commonly listed firm shall be selected as the third Appraiser.

(ii) The Company shall provide each Appraiser prompt access to such information as the Appraiser may reasonably request to enable it to determine the Appraised Asset Value. Each Appraiser shall work independently of each other Appraiser and must agree in writing that all Confidential Information and all other information obtained, analysis performed and conclusions reached in the engagement shall be kept confidential by such Appraiser and shall not be disclosed by such Appraiser to any other person (including any other Appraiser) in any manner whatsoever (other than with respect to providing a final report to the Company and the Members setting forth that Appraiser’s opinion on the Appraised Asset Value) before the Appraiser will be provided access to any Confidential Information.

(iii) Each Appraiser will determine the Appraised Asset Value within sixty (60) days of its engagement and furnish the Managing Member and the Class A Member its determination. Following receipt of all Appraised Asset Values for the Property in question, the Managing Member and the Class A Member will adopt the median Appraised Asset Value as the ▇▇▇▇-to-Market Value of the applicable Property.

(iv) The fees and expenses of the Appraisers will be divided equally between the Managing Member and the Class A Member.

(b) In the case of any Liability of the Company for which a Gross Liability Value is required by this Agreement to be determined, the Managing Member and the Class A Member shall negotiate in good faith the ▇▇▇▇-to-Market Value of the Company Liability taking into consideration the amount of cash that a willing assignor would pay to a willing, unrelated assignee to assume such Liability in an arm’s length transaction. If the Managing Member and the Class A Member are unable to agree on the ▇▇▇▇-to-Market Value of the applicable Liability, the ▇▇▇▇-to-Market Value will be determined in a manner corresponding to that set forth in Section 13.3(a) hereof; provided, however, in the event that the ▇▇▇▇-to-Market Value of an applicable Liability is being determined concurrently with the determination of the ▇▇▇▇-to-Market Value of Property or other Liabilities, all Market-to-Market Values shall be determined in the same process set forth in Section 13.3(a).
