ARTICLE 1

DEFINITIONS

Section 1.1Definitions.

The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

“12-Quarter Test” requires that, for each Quarter in the Incentive Trigger Period:

(a) the Company distributes Available Cash from Operating Surplus to holders of the Outstanding Class A Units and Common Units in an amount that on average exceeds the First Target Distribution on all of the Outstanding Class A Units and Common Units over the Incentive Trigger Period;

(b) the Company generates Adjusted Operating Surplus in an amount that, on average, equals or exceeds 100% of all distributions of Available Cash to the Outstanding Class A Units and Common Units up to the First Target Distribution on all of the Outstanding Class A Units and Common Units, plus 117.65% of any distributions to the Outstanding Class A Units and Common Units in excess of the First Target Distribution up to the Second Target Distribution and 133.33% of any distributions to the Outstanding Class A Units and Common Units in excess of the Second Target Distribution; and

(c) the Company does not reduce the amount of Available Cash distributed per Outstanding Class A Unit or Common Unit in respect of any such Quarter in the Incentive Trigger Period.

“4-Quarter Test” requires that, for each of (i) the last four full, consecutive, non-overlapping calendar Quarters in the Incentive Trigger Period, (ii) any four full consecutive, non-overlapping Quarters occurring after such last four Quarters in the Incentive Trigger Period,provided that the Company has distributed Available Cash from Operating Surplus to the holders of the Outstanding Class A Units and Common Units in an amount that equals or exceeds the Initial Quarterly Distribution for each Quarter occurring between the end of the Incentive Trigger Period and the beginning of the four full, consecutive, non-overlapping Quarters that satisfy the 4-Quarter Test, or (iii) any four full, consecutive, non-overlapping Quarters occurring partially within and partially after such last four Quarters of the Incentive Trigger Period:

(a) the Company distributes Available Cash from Operating Surplus to the holders of Outstanding Class A Units and Common Units in an amount that exceeds the First Target Distribution on all of the Outstanding Class A Units and Common Units;

(b) the Company generates Adjusted Operating Surplus in an amount that equals or exceeds 100% of all distributions of Available Cash to the Outstanding Class A Units and Common Units up to the First Target Distribution, plus 117.65% of any distributions to the Outstanding Class A Units and Common Units in excess of the First Target Distribution up to the Second Target Distribution and 133.33% of any distributions to the Outstanding Class A Units and Common Units in excess of the Second Target Distribution; and

(c) the Company does not reduce the amount of Available Cash distributed per Outstanding Class A Unit or Common Unit in respect of any of such four Quarters.

“Acquisition” means any transaction in which any Group Member acquires (through an asset acquisition, merger, stock acquisition or other form of investment) control over all or a portion of the assets, properties or business of another Person for the

purpose of increasing the asset base of the Company Group from the asset base of the Company Group existing immediately prior to such transaction;provided however, that any acquisition of properties or assets of another Person that is made solely for investment purposes shall not constitute an Acquisition under this Agreement.

“Additional Book Basis” means the portion of any remaining Carrying Value of an Adjusted Property that is attributable to positive adjustments made to such Carrying Value as a result of Book-Up Events. For purposes of determining the extent that Carrying Value constitutes Additional Book Basis:

(a) Any negative adjustment made to the Carrying Value of an Adjusted Property as a result of either a Book-Down Event or a Book-Up Event shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive adjustments made thereto pursuant to a Book-Up Event or Book-Down Event.

(b) If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event and the Carrying Value of other property is increased as a result of such Book-Down Event, an allocable portion of any such increase in Carrying Value shall be treated as Additional Book Basis;provided that the amount treated as Additional Book Basis as a result of such Book-Down Event shall not exceed the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceed the remaining Additional Book Basis attributable to all of the Company’s Adjusted Property after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event).

“Additional Book Basis Derivative Items” means any Book Basis Derivative Items that are computed with reference to Additional Book Basis. To the extent that the Additional Book Basis attributable to all of the Company’s Adjusted Property as of the beginning of any taxable period exceeds the Aggregate Remaining Net Positive Adjustments as of the beginning of such period (the “Excess Additional Book Basis”), the Additional Book Basis Derivative Items for such period shall be reduced by the amount that bears the same ratio to the amount of Additional Book Basis Derivative Items determined without regard to this sentence as the Excess Additional Book Basis bears to the Additional Book Basis as of the beginning of such period.

“Additional Member” means a Person admitted as a Member of the Company pursuant toSection 5.5 and who is shown as such on the books and records of the Company.

“Adjusted Capital Account” means the Capital Account maintained for each Member as of the end of each fiscal year of the Company, (a) increased by any amounts that such Member is obligated to restore under the standards set by Treasury Regulation Section 1.704-1(b)(2)(ii)(c) (or is deemed obligated to restore under Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5)) and (b) decreased by (i) the amount of all deductions in respect of depletion that, as of the end of such fiscal year are expected to be made to such Member’s Capital Account in respect of the oil and gas properties of the Company, (ii) the amount of all losses and deductions that, as of the end of such fiscal year, are reasonably expected to be allocated to such Member in subsequent years under Sections 704(e)(2) and 706(d) of the Code and Treasury Regulation Section 1.751-1(b)(2)(ii), and (iii) the amount of all distributions that, as of the end of such fiscal year, are reasonably expected to be made to such Member in subsequent years in accordance with the terms of this Agreement or otherwise to the extent they exceed offsetting increases to such Member’s Capital Account that are reasonably expected to occur during (or prior to) the year in which such distributions are reasonably expected to be made (other than increases as a result of a minimum gain chargeback pursuant toSection 6.1(d)(i) orSection 6.1(d)(ii)). The foregoing definition of Adjusted Capital Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. The “Adjusted Capital Account” of a Member in respect of a Common Unit, a Class A Unit, a Management Incentive Interest or any other Member Interest shall be the amount that such Adjusted Capital Account would be if such Common Unit, Class A Unit, Management Incentive Interest or other Member Interest were the only interest in the Company held by such Member from and after the date on which such Common Unit, Class A Unit, Management Incentive Interest or other Member Interest was first issued.

“Adjusted Operating Surplus” means, with respect to any period, (a) Operating Surplus generated with respect to that period; less (b) any net increase in Working Capital Borrowings with respect to that period; less (c) any net reduction in cash reserves for Operating Expenditures with respect to that period not relating to an Operating Expenditure made with respect to that period; plus

Section 3.7Conversion of Class A Units and Management Incentive Interests.

(a) Concurrently with any termination of the right of the holder(s) of the Class A Unit(s) to class voting pursuant toSection 11.8(d) that is not supported by the affirmative vote of any Common Units held by the holders of a majority of the Outstanding Class A Units or a majority of the Outstanding Management Incentive Interests or their Affiliates, then:

(i) each Outstanding Class A Unit shall automatically convert into, and shall thereafter constitute, one Common Unit; and

(ii) the holder(s) of the Management Incentive Interests shall have the right, exercisable upon notice to the Company delivered at any time within 180 days thereafter, to require the conversion by the Company of the Management Incentive Interests into a number of Common Units, the fair market value of which is equal to the fair market value of such Management Incentive Interests. For purposes of thisSection 3.7(a)(ii), the fair market value of the Management Incentive Interests shall be determined by agreement between the holder(s) thereof and the Conflicts Committee or, failing agreement within 30 days after the holder(s)’ demand for conversion, by an independent investment banking firm or other independent expert selected by the holder(s) and the Conflicts Committee, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the holder(s)’ demand for conversion, then each of the holder(s) and the Conflicts Committee shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent investment banking firm or other independent expert shall determine the fair market value of the Management Incentive Interests.

(b) The Class A Units and Management Incentive Interests shall also be convertible into Common Units pursuant to the Management Agreement.

(c) The transfer of a Class A Unit or Management Incentive Interests that have converted into a Common Unit shall be subject to the restrictions imposed by the Board of Directors necessary to preserve the uniformity of units, including the application ofSection 6.2(e).

(b) The Board of Directors may keep confidential from the Members, for such period of time as the Board of Directors determines, (i) any information that the Board of Directors determines to be in the nature of trade secrets or (ii) other information (including the Social Security Number or Tax Identification Number of any Member) the disclosure of which the Board of Directors determines (A) is not in the best interests of the Company Group, (B) could damage the Company Group or (C) that any Group Member is required by law, by the rules of any National Securities Exchange on which any Company Security is listed for trading, or by agreement with any third party to keep confidential (other than agreements with Affiliates of the Company the primary purpose of which is to circumvent the obligations set forth in thisSection 3.8).

ARTICLE 4

CERTIFICATES; RECORD HOLDERS;

TRANSFER OF INTERESTS; REDEMPTION OF INTERESTS

Section 4.1Certificates.

Upon the Company’s issuance of Common Units to any Person, the Company may issue one or more Certificates in the name of such Person evidencing the number of such Common Units being so issued. In addition, upon the request of any Person owning any other Company Securities other than Common Units, the Company shall issue to such Person one or more Certificates evidencing such other Company Securities. Certificates shall be executed on behalf of the Company by the Chairman of the Board, President or any Vice President and the Secretary or any Assistant Secretary. No Certificate representing Common Units shall be valid for any purpose until it has been countersigned by the Transfer Agent;provided, however, that if the Board of Directors elects to issue Common Units in global form, the Common Unit Certificates shall be valid upon receipt of a certificate from the Transfer Agent certifying that the Common Units have been duly registered in accordance with the directions of the Company. Any or all of the signatures required on the Certificate may be by facsimile. If any Officer or Transfer Agent who shall have signed or whose facsimile signature shall have been placed upon any such Certificate shall have ceased to be such Officer or Transfer Agent before such Certificate is issued by the Company, such Certificate may nevertheless be issued by the Company with the same effect as if such Person were such Officer or Transfer Agent at the date of issue. Certificates shall be consecutively numbered and shall be entered on the books and records of the Transfer Agent as they are issued and shall exhibit the holder’s name and number and type of Company Securities represented thereby.

Section 4.2Mutilated, Destroyed, Lost or Stolen Certificates.

If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate Officers on behalf of the Company shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Company Securities as the Certificate so surrendered.

(a) The appropriate Officers on behalf of the Company shall execute and deliver, and the Transfer Agent shall countersign, a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate:

(i) makes proof by affidavit, in form and substance satisfactory to the Company, that a previously issued Certificate has been lost, destroyed or stolen;

23

(ii) requests the issuance of a new Certificate before the Company has notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim;

(iii) if requested by the Company, delivers to the Company a bond, in form and substance satisfactory to the Company, with surety or sureties and with fixed or open penalty as the Company may direct to indemnify the Company and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and

(iv) satisfies any other reasonable requirements imposed by the Company.

If a Member fails to notify the Company within a reasonable time after he has notice of the loss, destruction or theft of a Certificate, and a transfer of the Member Interests represented by the Certificate is registered before the Company or the Transfer Agent receives such notification, the Member shall be precluded from making any claim against the Company or the Transfer Agent for such transfer or for a new Certificate.

(b) As a condition to the issuance of any new Certificate under thisSection 4.2, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith.

Section 4.3Record Holders.

The Company shall be entitled to recognize the Record Holder as the owner of a Member Interest and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Member Interest on the part of any other Person, regardless of whether the Company shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Member Interests are listed for trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Member Interests, as between the Company on the one hand, and such other Persons on the other, such representative Person shall be the Record Holder of such Member Interest.

Section 4.4Transfer Generally.

The term “transfer,” when used in this Agreement with respect to a Member Interest, shall be deemed to refer to any transaction pursuant to which the Company issues any Member Interest or by which the holder of a Member Interest assigns such Member Interest to another Person who is or becomes a Member, and includes a sale, assignment, gift, exchange or any other disposition by law or otherwise, including any transfer upon foreclosure of any pledge, encumbrance, hypothecation or mortgage. Other than with respect to an assignment by Atlas America of its Class A Units and Management Incentive Interests to Atlas Energy Management immediately following the execution of this Agreement on the Closing Date, no Member Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in thisArticle 4. Any transfer or purported transfer of a Member Interest not made in accordance with thisArticle 4 shall be, to the fullest extent permitted by law, null and void.

Section 4.5Registration and Transfer of Member Interests.

(a) The Company shall keep or cause to be kept on behalf of the Company a register that, subject to such reasonable regulations as it may prescribe and subject to the provisions ofSection 4.5(b), will provide for the registration and transfer of Member Interests. The Transfer Agent is hereby appointed registrar and transfer agent for the purpose of registering Common Units and transfers of such Common Units as herein provided. The Company shall not recognize transfers of Certificates evidencing Member Interests unless such transfers are effected in the manner described in thisSection 4.5. Upon surrender of a Certificate for registration of

24

transfer of any Member Interests evidenced by a Certificate, and subject to the provisions ofSection 4.5(b), the appropriate Officers of the Company shall execute and deliver, and in the case of Common Units, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the Record Holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Member Interests as were evidenced by the Certificate so surrendered.

(b) Except as provided inSection 4.7, the Company shall not recognize any transfer of Member Interests until the Certificates evidencing such Member Interests are surrendered for registration of transfer. No charge shall be imposed by the Company for such transfer;provided, that as a condition to the issuance of any new Certificate under thisSection 4.5(b), the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto.

(c) By acceptance of the transfer of any Member Interest in accordance with thisSection 4.5 and except as provided inSection 4.7, each transferee of a Member Interest (including any nominee holder or an agent or representative acquiring such Member Interests for the account of another Person) (i) shall be admitted to the Company as a Substituted Member with respect to the Member Interests so transferred to such Person when any such transfer or admission is reflected in the books and records of the Company, with or without execution of this Agreement, (ii) shall be deemed to agree to be bound by the terms of this Agreement, (iii) shall become the Record Holder of the Member Interests so transferred, (iv) represents that the transferee has the capacity, power and authority to enter into this Agreement, (v) grants powers of attorney to the Officers of the Company and any Liquidator of the Company in accordance withSection 2.6, and (vi) makes the consents and waivers contained in this Agreement. The transfer of any Member Interests and the admission of any new Member shall not constitute an amendment to this Agreement.

Section 4.6Restrictions on Transfers.

(a) In addition to the restrictions set forth inSection 4.5(b) and except as provided inSection 4.6(c)(b) below, but notwithstanding the other provisions of thisArticle 4, no transfer of any Member Interests shall be made if such transfer would violate the then applicable federal or state securities laws or rules and regulations of the Securities and Exchange Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer.

(b) In addition to the restrictions set forth inSection 4.5(b), the Company may impose restrictions on the transfer of Member Interests if it receives an Opinion of Counsel providing that such restrictions are necessary to avoid a significant risk of any Group Member becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes. The Board of Directors may impose such restrictions by amending this Agreement in accordance withArticle 11;provided,however, that any amendment that would result in the delisting or suspension of trading of any class of Member Interests on the principal National Securities Exchange on which such class of Member Interests is then traded must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Member Interests of such class.

(c) Nothing contained in thisArticle 4, or elsewhere in this Agreement, shall preclude the settlement of any transactions involving Member Interests entered into through the facilities of any National Securities Exchange on which such Member Interests are listed for trading.

(d) Subject to (i) the foregoing provisions of thisSection 4.5, (ii) Section 4.3, (iii) Section 4.6,(iv) with respect to any class or series of Member Interests other than the Class A Units, Common Units and Management Incentive Interests, the provisions of any amendment to this Agreement containing the statement of designations establishing such class or series, (v) the provisions of the Management Agreement and any other contractual provision binding on any Member and (vi) provisions of applicable law including the Securities Act, Member Interests shall be freely transferable to any Person.

Section 4.7Citizenship Certificates; Non-citizen Assignees.

(a) If any Group Member is or becomes subject to any federal, state or local law or regulation that the Board of Directors determines would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest

25

based on the nationality, citizenship or other related status of a Member or Assignee, the Board of Directors may request any Member or Assignee to furnish to the Board of Directors, within 30 days after receipt of such request, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other related status (or, if the Member or Assignee is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the Board of Directors may request. If a Member or Assignee fails to furnish to the Board of Directors within such 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the Board of Directors determines that a Member or Assignee is not an Eligible Citizen, the Member Interests owned by such Member or Assignee shall be subject to redemption in accordance with the provisions ofSection 4.8. In addition, the Board of Directors may require that the status of any such Member or Assignee be changed to that of a Non-citizen Assignee and, thereupon, such Member shall cease to be a member of the Company and shall have no voting rights, whether arising hereunder, under the Delaware Act, at law, in equity or otherwise, in respect of its Member Interests. The voting rights in respect of Member Interests of Non-citizen Assignees shall be deemed to have been exercised with the votes being distributed in the same ratios or for the same candidates for election as Directors as the votes of Members in respect of Member Interests other than those of Non-citizen Assignees are cast, either for, against or abstaining as to the matter or election.

(b) Upon dissolution of the Company, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant toSection 10.3, but shall be entitled to the cash equivalent thereof, and the Company shall provide cash in exchange for an assignment of the Non-citizen Assignee’s share of any distribution in kind. Such payment and assignment shall be treated for Company purposes as a purchase by the Company from the Non-citizen Assignee of his economic interest in the Company (representing his right to receive his share of such distribution in kind).

(c) At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the Board of Directors, request admission as a Substituted Member with respect to any Member Interests of such Non-citizen Assignee not redeemed pursuant toSection 4.8, such Non-citizen Assignee be admitted as a Member, and upon approval of the Board of Directors, such Non-citizen Assignee shall be admitted as a Member and shall no longer constitute a Non-citizen Assignee and shall reacquire all voting rights of his Member Interests.

Section 4.8Redemption of Member Interests of Non-citizen Assignees.

(a) If at any time a Member or Assignee fails to furnish a Citizenship Certification or other information requested within the 30-day period specified inSection 4.7(a), or if upon receipt of such Citizenship Certification or other information the Board of Directors determines, with the advice of counsel, that a Member or Assignee is not an Eligible Citizen, the Company may, unless the Member or Assignee establishes to the satisfaction of the Board of Directors that such Member or Assignee is an Eligible Citizen or has transferred his Member Interests to a Person who is an Eligible Citizen and who furnishes a Citizenship Certification to the Board of Directors prior to the date fixed for redemption as provided below, redeem the Member Interest of such Member or Assignee as follows:

(i) The Board of Directors shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Member or Assignee, at his last address designated on the records of the Company or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certificate evidencing the Redeemable Interests and that on and after the date fixed for redemption no further allocations or distributions to which the Member would otherwise be entitled in respect of the Redeemable Interests will accrue or be made.

(ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Member Interests of the class to be so redeemed multiplied by the number of Member Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the Board of Directors, in cash or by delivery of a promissory note of the Company in the

26

principal amount of the redemption price, bearing interest at the Prime Rate annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii) Upon surrender by or on behalf of the Member or Assignee, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank, the Member or Assignee or his duly authorized representative shall be entitled to receive the payment therefor.

(iv) After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Member Interests.

(b) The provisions of thisSection 4.8 shall also be applicable to Member Interests held by a Member or Assignee as nominee of a Person determined to be other than an Eligible Citizen.

(c) Nothing in thisSection 4.8 shall prevent the recipient of a notice of redemption from transferring his Member Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the Board of Directors shall withdraw the notice of redemption, provided the transferee of such Member Interest certifies to the satisfaction of the Board of Directors in a Citizenship Certification that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

Section 5.3Interest and Withdrawal.

No interest shall be paid by the Company on Capital Contributions. No Member shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon dissolution of the Company may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Member shall have priority over any other Member either as to the return of Capital Contributions or as to profits, losses or distributions.

Section 5.4Capital Accounts.

(a) The Company shall maintain for each Member (or a beneficial owner of Member Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Company in accordance with Section 6031(c) of the Code or any other method acceptable to the Company) owning a Member Interest a separate Capital Account with respect to such Member Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Company with respect to such Member Interest pursuant to this Agreement and (ii) all items of Company income and gain (including Simulated Gain and income and gain exempt from tax) computed in accordance withSection 5.4(b) and allocated with respect to such Member Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Member Interest pursuant to this Agreement and (y) all items of Company deduction and loss (including Simulated Depletion and Simulated Loss) computed in accordance withSection 5.4(b) and allocated with respect to such Member Interest pursuant toSection 6.1.

(b) For purposes of computing the amount of any item of income, gain, loss or deduction, Simulated Depletion, Simulated Gain or Simulated Loss which is to be allocated pursuant toArticle 6 and is to be reflected in the Members’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose),provided, that:

(i) Solely for purposes of thisSection 5.4, the Company shall be treated as owning directly its proportionate share (as determined by the Board of Directors based upon the provisions of the applicable Group Member Agreement) of all property owned by any other Group Member that is classified as a partnership for federal income tax purposes.

(ii) All fees and other expenses incurred by the Company to promote the sale of (or to sell) a Member Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Members pursuant toSection 6.1.

(iii) Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss, deduction, Simulated Depletion, Simulated Gain and Simulated Loss shall be made without regard to any election under Section 754 of the Code which may be made by the Company and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

28

(iv) Any income, gain, loss, Simulated Gain or Simulated Loss attributable to the taxable disposition of any Company property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Company’s Carrying Value with respect to such property as of such date.

(v) In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery amortization or Simulated Depletion attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Company were equal to the Agreed Value of such property. Upon an adjustment pursuant toSection 5.4(d) to the Carrying Value of any Company property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery, amortization or Simulated Depletion attributable to such property shall be determined (A) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment and (B) using any method of depreciation, cost recovery, amortization or Simulated Depletion that the Board of Directors may adopt.

(vi) If the Company’s adjusted basis in a depreciable or cost recovery property is reduced for federal income tax purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction shall, solely for purposes hereof, be deemed to be an additional depreciation or cost recovery deduction in the year such property is placed in service and shall be allocated among the Members pursuant toSection 6.1. Any restoration of such basis pursuant to Section 48(q)(2) of the Code shall, to the extent possible, be allocated in the same manner to the Members to whom such deemed deduction was allocated.

(c) A transferee of a Member Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Member Interest so transferred.

(i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Member Interests for cash or Contributed Property and the issuance of Member Interests as consideration for the provision of services, the Capital Account of all Members and the Carrying Value of each Company property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property immediately prior to such issuance and had been allocated to the Members at such time pursuant toSection 6.1 in the same manner as any item of gain, loss, Simulated Gain or Simulated Loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Company assets (including cash or cash equivalents) immediately prior to the issuance of additional Member Interests shall be determined by the Board of Directors using such method of valuation as it may adopt;provided,however, that the Board of Directors, in arriving at such valuation, must take fully into account the fair market value of the Member Interests of all Members at such time. The Board of Directors shall allocate such aggregate value among the assets of the Company (in such manner as it determines) to arrive at a fair market value for individual properties.

(ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Member of any Company property (other than a distribution of cash that is not in redemption or retirement of a Member Interest), the Capital Accounts of all Members and the Carrying Value of all Company property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated to the Members, at such time, pursuant toSection 6.1 in the same manner as any item of gain, loss, Simulated Gain or Simulated Loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market value of all Company assets (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant toSection 10.3 or in the case of a deemed distribution, be determined and allocated in the same manner as that provided inSection 5.4(c)(i) or (B) in the case of a liquidating distribution pursuant toSection 10.3, be determined and allocated by the Liquidator using such method of valuation as it may adopt.

The issuance of Company Securities pursuant toSection 5.5 shall be subject to the limitation that no fractional Units shall be issued by the Company.

Section 5.7No Preemptive Rights.

No Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Company Security, whether unissued, held by the Company or hereafter created.

Section 5.8Splits and Combinations.

(a) Subject toSection 5.6,Section 5.8(d) andSection 6.7, the Company may make a Pro Rata distribution of Company Securities of any class or series to all Record Holders of Company Securities of such class or series or may effect a subdivision or combination of Company Securities so long as, after any such event, each Member shall have the same Percentage Interest in the Company as before such event, and any amounts calculated on a per Unit basis or stated as a number of Units are proportionately adjusted retroactive to the date of formation of the Company.

30

(b) Whenever such a distribution, subdivision or combination of Company Securities is declared, the Board of Directors shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The Board of Directors also may cause a firm of independent public accountants selected by it to calculate the number of Company Securities to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The Board of Directors shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation.

(c) Promptly following any such distribution, subdivision or combination, the Company may issue Certificates to the Record Holders of Company Securities as of the applicable Record Date representing the new number of Company Securities held by such Record Holders, or the Board of Directors may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Company Securities Outstanding, the Company shall require, as a condition to the delivery to a Record Holder of such new Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date.

(d) The Company shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions ofSection 5.6 and this Section 5.8(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

Section 5.9Fully Paid and Non-Assessable Nature of Member Interests.

Section 5.10Registration Rights of Atlas America and its Affilitaes.

(a) If (i) Atlas Energy Management, Atlas America or any of their Affiliates (including for purposes of thisSection 5.10, any Person that is an Affiliate of Atlas Energy Management or Atlas America at the date hereof notwithstanding that it may later cease to be an Affiliate of Atlas Energy Management or Atlas America) holds Company Securities that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Company Securities (the “Holder”) to dispose of the number of Company Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Company shall file with the Commission as promptly as practicable after receiving such request, and use all commercially reasonable efforts to cause to become effective and remain effective for a period following its effective date until all Company Securities covered by such registration statement have been sold or until Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) becomes available for such Company Securities, a registration statement under the Securities Act registering the offering and sale of the number of Company Securities specified by the Holder (which registration statement may constitute a “shelf” registration statement covering the Company Securities specified by the Holder on an appropriate form under Rule 415 under the Securities Act, or any similar rule that may be adopted by the Commission);provided,however, that the Company shall not be required to effect more than three registrations pursuant to thisSection 5.10(a); andprovided further,however, that if the Conflicts Committee determines in good faith that the requested registration, or use of any prospectus forming a part thereof, would be materially detrimental to the Company and its Members because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Company, (y) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (z) render the Company unable to comply with requirements under applicable securities laws, then the Company shall have the right to postpone such requested registration or use of any such prospectus for a

31

period of not more than three months after receipt of the Holder’s request, such right to postpone a requested registration or use of any such prospectus pursuant to thisSection 5.10(a) not to be utilized more than once in any twelve-month period. Except as provided in the preceding sentence, the Company shall be deemed not to have used all commercially reasonable efforts to keep the registration statement effective during the applicable period if it voluntarily takes any action that would result in Holders of Company Securities covered thereby not being able to offer and sell such Company Securities at any time during such period, unless such action is required by applicable law. In connection with any registration pursuant to thisSection 5.10(a), the Company shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request;provided,however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Company would become subject to general service of process or to taxation or qualification to do business as a foreign corporation, limited liability company or partnership doing business in such jurisdiction solely as a result of such registration, and (B) such documents as may be necessary to apply for listing or to list the Company Securities subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such Company Securities in such states. Except as set forth inSection 5.10(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Company, without reimbursement by the Holder.

(b) If the Company shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of the Company for cash (other than an offering relating solely to an employee benefit plan or a business combination), the Company shall use all commercially reasonable efforts to include such number or amount of securities held by any Holder in such registration statement as the Holder shall request;provided, that the Company is not required to make any effort or take any action to so include the securities of the Holder once the registration statement becomes or is declared effective by the Commission, including any registration statement providing for the offering from time to time of securities pursuant to Rule 415 of the Securities Act. If the proposed offering pursuant to thisSection 5.10(b) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Company and the Holder in writing that in their opinion the inclusion of all or some of the Holder’s Company Securities, in addition to the equity securities of the Company that the Company proposes to sell, would adversely and materially affect the success of the offering, the Company shall include in such offering only that number or amount, if any, of securities held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth inSection 5.10(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Company, without reimbursement by the Holder.

(c) If underwriters are engaged in connection with any registration referred to in thisSection 5.10, the Company shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Company’s obligation underSection 7.7, the Company shall, to the fullest extent permitted by law, indemnify and hold harmless the Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Indemnified Persons”) from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (hereinafter referred to in thisSection 5.10(c) as a “claim” and in the plural as “claims”) based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which any Company Securities were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or in any amendment or supplement thereto (if used during the period the Company is required to keep the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading; provided, however, that the Company shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, such

32

preliminary, summary or final prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Indemnified Person specifically for use in the preparation thereof.

(d) The rights to cause the Company to register Company Securities pursuant to thisSection 5.10 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such Company Securities, provided (i) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Company Securities with respect to which such registration rights are being assigned; and (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in thisSection 5.10.

(e) Any request to register Company Securities pursuant to thisSection 5.10 shall (i) specify the Company Securities intended to be offered and sold by the Person making the request, (ii) express such Person’s present intent to offer such Company Securities for distribution, (iii) describe the nature or method of the proposed offer and sale of Company Securities, and (iv) contain the undertaking of such Person to provide all such information and materials and take all action as may be required in order to permit the Company to comply with all applicable requirements in connection with the registration of such Company Securities.

(iv)Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Company income, gain and Simulated Gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant toSection 6.1(d)(i) or(ii).

(v)Gross Income Allocations. In the event any Member has a deficit balance in its Capital Account at the end of any Company taxable period in excess of the sum of (A) the amount such Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Member is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Member shall be specially allocated items of Company gross income, gain and Simulated Gain in the amount of such excess as quickly as possible;provided, that an allocation pursuant to thisSection 6.1(d)(v) shall be made only if and to the extent that such Member would have a deficit balance in its Capital Account as adjusted after all other allocations provided for in thisSection 6.1 have been tentatively made as if thisSection 6.1(d)(v) were not in this Agreement.

(vi)Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Members in accordance with their respective Percentage Interests. If the Board of Directors determines that the Company’s Nonrecourse

35

Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the Board of Directors is authorized, upon notice to the other Members, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

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

(viii)Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Members agree that Nonrecourse Liabilities of the Company in excess of the sum of (A) the amount of Company Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Members in accordance with their respective Percentage Interests.

(ix)Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain or Simulated Gain (if the adjustment increases the basis of the asset) or loss or Simulated Loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(x)Curative Allocation.

(A) Notwithstanding any other provision of thisSection 6.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss, deduction, Simulated Depletion, Simulated Gain or Simulated Loss allocated to each Member pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Member under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in thisSection 6.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Company Minimum Gain and (2) Member Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Member Nonrecourse Debt Minimum Gain. Allocations pursuant to thisSection 6.1(d)(x)(A) shall only be made with respect to Required Allocations to the extent the Board of Directors reasonably determines that such allocations will otherwise be inconsistent with the economic agreement among the Members. Further, allocations pursuant to thisSection 6.1(d)(x)(A) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the Board of Directors determines that such allocations are likely to be offset by subsequent Required Allocations.

(B) The Board of Directors shall, with respect to each taxable period, (1) apply the provisions ofSection 6.1(d)(x)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant toSection 6.1(d)(x)(A) among the Members in a manner that is likely to minimize such economic distortions.

36

(xi)Corrective Allocations. In the event of any allocation of Additional Book Basis Derivative Items or any Book-Down Event or any recognition of a Net Termination Loss, the following rules shall apply:

(A) In the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss underSection 5.4(c) hereof) to only certain Members (the “Allocated Members”), the Board of Directors shall allocate additional items of gross income, gain and Simulated Gain away from the Allocated Members to the extent that the Additional Book Basis Derivative Items allocated to the Allocated Members exceed their Share of Additional Book Basis Derivative Items and to the remaining Members (or shall allocate additional items of deduction, loss, Simulated Depletion and Simulated Loss away from the other Members and to the Allocated Members). For this purpose, a Member shall be treated as having been allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that otherwise have been allocated to the Member under this Agreement. Any allocation made pursuant to thisSection 6.1(d)(xi)(A) shall be made after all of the other Agreed Allocations have been made as if thisSection 6.1(d)(xi)were not in this Agreement and, to the extent necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations.

(B) In the case of any negative adjustments to the Capital Accounts of the Members resulting from a Book-Down Event or from the recognition of a Net Termination Loss, such negative adjustment (1) shall first be allocated, to the extent of the Aggregate Remaining Net Positive Adjustments, in such a manner, as determined by the Board of Directors, that to the extent possible the aggregate Capital Accounts of the Members will equal the amount that would have been the Capital Account balance of the Members if no prior Book-Up Events had occurred, and (2) any negative adjustment in excess of the Aggregate Remaining Net Positive Adjustments shall be allocated pursuant toSection 6.1(c) hereof.

(C) In making the allocations required under thisSection 6.1(d)(xi), the Board of Directors may apply whatever conventions or other methodology it determines will satisfy the purpose of thisSection 6.1(d)(xi).

Section 6.2Allocations for Tax Purposes.

(a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Members in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant toSection 6.1.

(b) The deduction for depletion with respect to each separate oil and gas property (as defined in Section 614 of the Code) shall be computed for federal income tax purposes separately by the Members rather than by the Company in accordance with Section 613A(c)(7)(D) of the Code. Except as provided inSection 6.2(c)(iii)), for purposes of such computation (before taking into account any adjustments resulting from an election made by the Company under Section 754 of the Code), the adjusted tax basis of each oil and gas property (as defined in Section 614 of the Code) shall be allocated among the Members in accordance with their respective Percentage Interests.

Each Member shall separately keep records of his share of the adjusted tax basis in each oil and gas property, allocated as provided above, adjust such share of the adjusted tax basis for any cost or percentage depletion allowable with respect to such property, and use such adjusted tax basis in the computation of its cost depletion or in the computation of his gain or loss on the disposition of such property by the Company.

(c) Except as provided inSection 6.2(c)(iii), for the purposes of the separate computation of gain or loss by each Member on the sale or disposition of each separate oil and gas property (as defined in Section 614 of the Code), the Company’s allocable share of the “amount realized” (as such term is defined in Section 1001(b) of the Code) from such sale or disposition shall be allocated for federal income tax purposes among the Members as follows:

(i) first, to the extent such amount realized constitutes a recovery of the Simulated Basis of the property, to the Members in the same proportion as the depletable basis of such property was allocated to the Members pursuant toSection 6.2(b) (without regard to any special allocation of basis underSection 6.2(c)(iii));

37

(ii) second, the remainder of such amount realized, if any, to the Members so that, to the maximum extent possible, the amount realized allocated to each Member under thisSection 6.2(c)(ii) will equal such Member’s share of the Simulated Gain recognized by the Company from such sale or disposition.

(iii) The Members recognize that with respect to Contributed Property and Adjusted Property there will be a difference between the Carrying Value of such property at the time of contribution or revaluation, as the case may be, and the adjusted tax basis of such property at that time. All items of tax depreciation, cost recovery, amortization, adjusted tax basis of depletable properties, amount realized and gain or loss with respect to such Contributed Property and Adjusted Property shall be allocated among the Members to take into account the disparities between the Carrying Values and the adjusted tax basis with respect to such properties in accordance with the principles of Treasury Regulation Section 1.704-3(d) except as otherwise determined by the Board of Directors with respect to goodwill.

(iv) Any elections or other decisions relating to such allocations shall be made by the Board of Directors in any manner that reasonably reflects the purpose and intention of the Agreement.

(d) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, other than an oil and gas property pursuant toSection 6.2(c), items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Members as follows:

(i) (A) In the case of a Contributed Property, such items attributable thereto shall be allocated among the Members in the manner provided under Section 704(c) of the Code that takes into account the variation between the Agreed Value of such property and its adjusted basis at the time of contribution; and (B) any item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Members in the same manner as its correlative item of “book” gain or loss is allocated pursuant toSection 6.1.

(ii) (A) In the case of an Adjusted Property, such items shall (1) first, be allocated among the Members in a manner consistent with the principles of Section 704(c) of the Code to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant toSection 5.4(c)(i) orSection 5.4(c)(ii), and (2) second, in the event such property was originally a Contributed Property, be allocated among the Members in a manner consistent withSection 6.2(d)(i)(A); and (B) any item of Residual Gain or Residual Loss attributable to an Adjusted Property shall be allocated among the Members in the same manner as its correlative item of “book” gain or loss is allocated pursuant toSection 6.1.

(iii) The Board of Directors shall apply the principles of Treasury Regulation Section 1.704-3(d) to eliminate Book-Tax Disparities except as otherwise determined by the Board of Directors with respect to goodwill.

(e) For the proper administration of the Company and for the preservation of uniformity of the Common Units (or any class or classes thereof), the Board of Directors shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations for federal income tax purposes of income (including gross income) or deductions; and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Common Units (or any class or classes thereof). The Board of Directors may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in thisSection 6.2(e) only if such conventions, allocations or amendments would not have a material adverse effect on the Members, the holders of any class or classes of Common Units issued and Outstanding or the Company, and if such allocations are consistent with the principles of Section 704 of the Code.

38

(f) The Board of Directors may not determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) or to depreciate or amortize such portion of an adjustment using a predetermined rate derived from the depreciation or amortization method and useful life applied to the Company’s common basis of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6), Treasury Regulation Section 1.197-2(g)(3), any successor regulations thereto or the legislative history of Section 743 of the Code. If the Board of Directors determines that such reporting position cannot be taken, the Board of Directors may adopt depreciation and amortization conventions under which all purchasers acquiring Common Units in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Company’s property. If the Board of Directors chooses not to utilize such aggregate method, the Board of Directors may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Member Interests, so long as such conventions would not have a material adverse effect on the Members or the Record Holders of any class or classes of Common Units.

(g) Any gain allocated to the Members upon the sale or other taxable disposition of any Company asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to thisSection 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Members (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

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

(i) Each item of Company income, gain, loss and deduction shall, for federal income tax purposes, be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Members as of the opening of the National Securities Exchange on which the Common Units are then traded on the first Business Day of each month;provided,however, such items for the period beginning on the Closing Date and ending on the last day of the month in which the Option Closing Date or the expiration of the Over-Allotment Option occurs shall be allocated to the Members as of the opening of the National Securities Exchange on which the Common Units are then traded on the first Business Day of the next succeeding month; andprovided,further, that gain or loss on a sale or other disposition of any assets of the Company or any other extraordinary item of income or loss realized and recognized other than in the ordinary course of business, as determined by the Board of Directors, shall be allocated to the Members as of the opening of the National Securities Exchange on which the Common Units are then traded on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The Board of Directors may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

(j) Allocations that would otherwise be made to a Member under the provisions of thisArticle 6 shall instead be made to the beneficial owner of Common Units held by a nominee in any case in which the nominee has furnished the identity of such owner to the Company in accordance with Section 6031(c) of the Code or any other method determined by the Board of Directors.

Section 6.3Requirement and Characterization of Distributions; Distributions to Record Holders.

(a) Within 45 days following the end of each Quarter commencing with the Quarter ending on December 31, 2006, an amount equal to 100% of Available Cash with respect to such Quarter shall, subject to Section 18-607 of the Delaware Act, be distributed in accordance with thisArticle 6 by the Company to the Members as of the Record Date selected by our Board of Directors for such distribution (or by an Officer designated by our Board of Directors to select the Record Date for such distribution). All amounts of Available Cash distributed by the Company on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Company to the Members pursuant toSection 6.4 equals the Operating

39

Surplus from the Closing Date through the close of the date of determination. Any remaining amounts of Available Cash distributed by the Company on such date shall, except as otherwise provided inSection 6.4, be deemed to be “Capital Surplus.” All distributions required to be made under this Agreement shall be made subject to Section 18-607 or Section 18-804 of the Delaware Act.

(b) NotwithstandingSection 6.3(a), in the event of the dissolution and liquidation of the Company, all receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of,Section 10.3.

(c) The Company may treat taxes paid by the Company on behalf of, or amounts withheld with respect to, all or less than all of the Members, as a distribution of Available Cash to such Members.

(d) Each distribution in respect of a Member Interest shall be paid by the Company, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such Member Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Company’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 6.4Distributions of Available Cash from Operating Surplus.

(a)During the MII Vesting Period. Available Cash with respect to any Quarter ending prior to or on the date of the end of the MII Vesting Period that is deemed to be Operating Surplus pursuant to the provisions ofSection 6.3 orSection 6.6 shall, subject to Section 18-607 of the Delaware Act, be distributed, except as otherwise required bySection 5.5(b) in respect of other Company Securities issued pursuant thereto, as follows: (A) 2% to the holder(s) of the Class A Units, Pro Rata and (B) 98% to the holders of the Common Units, Pro Rata.

(b)After the MII Vesting Period. Available Cash with respect to each Quarter after the MII Vesting Period that is deemed to be Operating Surplus pursuant to the provisions ofSection 6.3 orSection 6.6 shall, subject to Section 18-607 of the Delaware Act, be distributed, except as otherwise required bySection 5.5(b) in respect of additional Company Securities issued pursuant thereto, as follows:

(i) First, (A) 2% to the holders of the Class A Units, Pro Rata, and (B) 98% to the holders of Common Units, Pro Rata, until there has been distributed in respect of each Class A Unit and each Common Unit then Outstanding an amount equal to the Initial Quarterly Distribution for such Quarter;

(ii) Second, (A) 2% to the holders of Class A Units, Pro Rata, and (B) 98% to the holders of Common Units, Pro Rata, until there has been distributed in respect of each Class A Unit and each Common Unit then Outstanding an amount equal to the Initial Quarterly Distribution for such Quarter plus $0.06 (the “First Target Distribution”);

(iii) Third, (A) 2% to the holders of the Class A Units, Pro Rata, (B) 83% to the holders of the Common Units, Pro Rata, and (C) 15% to the holders of the Management Incentive Interests, Pro Rata, until there has been distributed in respect of each Class A Unit and each Common Unit then Outstanding an amount equal to the Initial Quarterly Distribution for such Quarter plus $0.17 (the “Second Target Distribution”); and

(iv) Thereafter, (A) 2% to the holders of the Class A Units, Pro Rata, (B) 73% to the holders of the Common Units, Pro Rata, and (C) 25% to the holders of the Management Incentive Interests, Pro Rata.

Section 6.5Payment of the EP MID.

If both the 12-Quarter Test and the 4-Quarter Test have been met with respect to the Incentive Trigger Period, an EP MID shall be made contemporaneously with the distribution paid in respect of the Class A Units and Common Units pursuant toSection 6.4 for the fourth calendar quarter in the 4-Quarter Test to the holder of the Management Incentive Interests.

40

Section 6.6Distributions of Available Cash from Capital Surplus.

Available Cash that is deemed to be Capital Surplus pursuant to the provisions ofSection 6.3(a) shall, subject to Section 18-607 of the Delaware Act, be distributed, unless the provisions ofSection 6.3 require otherwise, 100% to the holders of Common Units, Pro Rata, until a hypothetical holder of a Common Unit acquired on the Closing Date has received with respect to such Common Unit, during the period since the Closing Date through such date, distributions of Available Cash that are deemed to be Capital Surplus in an aggregate amount equal to the Initial Issue Price. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance withSection 6.4.

Section 6.7Adjustment of Initial Quarterly Distribution, First Target Distribution, Second Target Distribution and Unrecovered Capital.

(a) The Initial Quarterly Distribution, First Target Distribution, Second Target Distribution and Unrecovered Capital shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Company Securities in accordance withSection 5.8. In the event of a distribution of Available Cash that is deemed to be from Capital Surplus, the then applicable Initial Quarterly Distribution, First Target Distribution and Second Target Distribution shall be adjusted proportionately downward to equal the product obtained by multiplying the otherwise applicable Initial Quarterly Distribution, First Target Distribution and Second Target Distribution, as the case may be, by a fraction of which the numerator is the Unrecovered Capital of the Common Units immediately after giving effect to such distribution and of which the denominator is the Unrecovered Capital of the Common Units immediately prior to giving effect to such distribution.

(b) The Initial Quarterly Distribution, First Target Distribution and Second Target Distribution shall also be subject to adjustment pursuant toSection 6.8.

Section 6.8Entity-Level Taxation.

If legislation is enacted or the interpretation of existing language is modified by a governmental taxing authority so that a Company Group member is treated as an association taxable as a corporation or is otherwise subject to an entity-level tax for federal, state or local income tax purposes, then the Board of Directors may reduce the Initial Quarterly Distribution, the First Target Distribution and the Second Target Distribution by the amount of the income taxes that are payable by reason of any such new legislation or interpretation (the “Incremental Income Tax”), or any portion thereof selected by the Board of Directors, in the manner provided in thisSection 6.8. If the Board of Directors elects to reduce the Initial Quarterly Distribution, the First Target Distribution and the Second Target Distribution for any Quarter with respect to all or a portion of the Incremental Income Taxes, the Board of Directors shall estimate for such Quarter the Company Group’s aggregate liability (the “Estimated Incremental Quarterly Tax Amount”) for all (or the relevant portion of) such Incremental Income Taxes;provided that any difference between such estimate and the actual liability for Incremental Income Taxes (or the relevant portion thereof) for such Quarter may, to the extent determined by the Board of Directors, be taken into account in determining the Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the Initial Quarterly Distribution shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of thisSection 6.8 times (b) the quotient obtained by dividing (i) Available Cash with respect to such Quarter by (ii) the sum of Available Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the Board of Directors. For purposes of the foregoing, Available Cash with respect to a Quarter will be deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

(b) The Board of Directors shall consist of 7 natural Persons. Each Director shall be elected as provided inSection 7.1(c) and shall serve in such capacity until his or her successor has been duly elected and qualified or until such Director dies, resigns or is removed. A Director may resign at any time upon written notice to the Company. The Board of Directors may from time to time determine the number of Directors then constituting the whole Board of Directors, but the Board of Directors shall not decrease the number of Persons that constitute the whole Board of Directors if such decrease would shorten the term of any Director.

(c) The persons comprising the initial Board of Directors shall be as follows: Edward E. Cohen, Jonathan Z. Cohen, Richard D. Weber, Matthew A. Jones, Walter C. Jones, Ellen F. Warren and Bruce M. Wolf. Such persons shall serve as members of the Board of Directors until the annual meeting of Members to be held in 2007 and until their successors are duly elected and qualified, or until their earlier death, resignation or removal.

The nomination of Persons to serve as Directors and the election of the Board of Directors shall be in accordance withArticle 11.

(d) Any Director may be removed at any time, with or without cause, only by the affirmative vote or consent of a Unit Majority.

(e) Subject to the rights of the holders of any series of Member Interests, vacancies existing on the Board of Directors created by virtue of an increase in the size of the Board of Directors or resulting from the death, resignation or removal of a Director may be filled only by the affirmative vote of a majority of the Directors then serving, even if less than a quorum. Any Director chosen to fill a vacancy shall hold office until the next annual meeting of Members and until his or her successor has been duly elected and qualified or until such Director’s earlier death, resignation or removal.

(f) Directors need not be Members. The Board of Directors may, from time to time and by the adoption of resolutions, establish qualifications for Director.

(g) Unless otherwise required by the Delaware Act, other law or the provisions hereof,

(i) each member of the Board of Directors shall have one vote;

(ii) the presence at a meeting of the Board of Directors of a majority of the members of the Board of Directors shall constitute a quorum at any such meeting for the transaction of business; and

(iii) the act of a majority of the members of the Board of Directors present at a meeting of the Board of Directors at which a quorum is present shall be deemed to constitute the act of the Board of Directors.

43

(h) Regular meetings of the Board of Directors and any committee thereof shall be held at such times and places as shall be designated from time to time by resolution of the Board of Directors or such committee.

Section 7.7Indemnification.

(a) To the fullest extent permitted by law as it currently exists and to such greater extent as applicable law hereafter may permit, but subject to the limitations expressly provided in this Agreement, the Company shall indemnify, hold harmless and defend any Person who was or is a party or is threatened to be made a party to, or otherwise requires representation of counsel in connection with, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including an action by or in the right of the Company) by reason of the fact that such Person is an Indemnitee or by reason of any action alleged to have been taken or omitted in such capacity, against losses, expenses (including attorneys’ fees of counsel for such Indemnitee), judgments, fines, damages, penalties, interest, liabilities and amounts paid in settlement actually and reasonably incurred by the Person in connection with such action, suit or proceeding;provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to thisSection 7.7(a), the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the Person acted in bad faith or engaged in fraud, willful misconduct or, with respect to any criminal action or proceeding, acted with the knowledge that the Person’s conduct was unlawful.

(b) To the extent an Indemnitee has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to inSection 7.7(a), or in the defense of any claim, issue or matter therein, such Person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such Person in connection therewith.

(c) Expenses (including reasonable attorneys’ fees of counsel for such Indemnitee) incurred by an Indemnitee in defending any action, suit or proceeding referred to inSection 7.7(a) shall be paid by the Company, when and as incurred, in advance of the final disposition of such action, suit or proceeding and in advance of any determination that such Indemnitee is not entitled to be indemnified, upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “Final Adjudication”) that such Person is not entitled to be indemnified by the Company as authorized in thisSection 7.7.

(d) The indemnification, advancement of expenses and other provisions of thisSection 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Member Interests, as a matter of law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity (including any capacity under the Underwriting Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(e) The Company may purchase and maintain insurance, on behalf of its Directors and Officers, and such other Persons as the Board of Directors shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(f) For purposes of the definition of Indemnitee inSection 1.1, the Company shall be deemed to have requested a Person to serve as fiduciary of an employee benefit plan whenever the performance by such Person of his duties to the Company also imposes duties on, or otherwise involves services by, such Person to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of

48

Section 7.7(a); and action taken or omitted by such Person with respect to any employee benefit plan in the performance of such Person’s duties for a purpose reasonably believed by him to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in, or not opposed to, the best interests of the Company.

(g) Any indemnification pursuant to thisSection 7.7 shall be made only out of the assets of the Company, it being agreed that the Members shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification.

(h) An Indemnitee shall not be denied indemnification in whole or in part under thisSection 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(i) If a claim underSection 7.7 is not paid in full by the Company within 60 days after a written claim has been received by the Company, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be 20 days, the Indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the Indemnitee shall be entitled to be paid also the reasonable expenses of prosecuting or defending such suit. In (i) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the Indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the Company shall be entitled to recover such expenses upon a Final Adjudication that, the Indemnitee has not met any applicable standard for indemnification set forth in this Agreement. Neither the failure of the Company (including its Directors who are not parties to such action, a committee of such Directors, independent legal counsel, or its Members) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in this Agreement, nor an actual determination by the Company (including its Directors who are not parties to such action, a committee of such Directors, independent legal counsel, or its Members) that the Indemnitee has not met the applicable standard of conduct shall create a presumption that the Indemnitee has not met the applicable standard of conduct, or, in the case of such a suit brought by the Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified or to such advancement of expenses, under thisSection 7.7 or otherwise shall be on the Company.

(j) The Company may indemnify any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in the right of the Company) by reason of the fact that the Person is or was an employee (other than an Officer) or agent of the Company, or, while serving as an employee (other than an Officer) or agent of the Company is or was serving at the request of the Company as a manager, director, officer, employee, partner, fiduciary, trustee or agent of another Group Member or another Person to the extent

(i) permitted by the laws of the State of Delaware as from time to time in effect, and

(ii) authorized by the Board of Directors.

The Company may, to the extent permitted by Delaware law and authorized by the Board of Directors, pay expenses (including attorneys’ fees) reasonably incurred by any such employee or agent in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding, upon such terms and conditions as the Board of Directors determine. The provisions of thisSection 7.7(j) shall not constitute a contract right for any such employee or agent.

(k) The indemnification, advancement of expenses and other provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

49

(l) Except to the extent otherwise provided inSection 7.7(j), the right to be indemnified and to receive advancement of expenses in thisSection 7.7 shall be a contract right. No amendment, modification or repeal of thisSection 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Company, nor the obligations of the Company to indemnify any such Indemnitee under and in accordance with the provisions of thisSection 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.8Exculpation of Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable to the Company, the Members or any other Persons who have acquired interests in Company Securities for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b) Subject to its obligations and duties as Board of Directors set forth in thisArticle 7, the Board of Directors may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the Board of Directors shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the Board of Directors in good faith.

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Company, to the Members or any other Persons who have acquired interests in Company Securities, none of the Directors and any other Indemnitee acting in connection with the Company’s business or affairs shall be liable to the Company, to any Member or any other Persons who have acquired interests in Company Securities for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate or otherwise modify the duties (including fiduciary duties) and liabilities of an Indemnitee otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of such Indemnitee.

(d) Any amendment, modification or repeal of thisSection 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of any Indemnitee under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

(e) An Indemnitee shall be fully protected in relying in good faith upon the records of the Company and upon information, opinions, reports or statements presented by a Director, Member or liquidating trustee, an Officer or employee of the Company, or committees of the Company, Members or Directors, or by any other person as to matters that the Member, Director or liquidating trustees reasonably believes are within such other Person’s professional or expert competence, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits or losses of the Company, or the value and amount of assets or reserves or contracts, agreements or other undertakings that would be sufficient to pay claims and obligations of the Company or to make reasonable provision to pay such claims and obligations, or any other facts pertinent to the existence and amount of assets from which distributions to members or creditors might properly be paid.

Section 7.9Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties.

(a) Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever a potential conflict of interest exists or arises between any Affiliate of the Company, on the one hand, and the Company or any Group Member, on the other, any resolution or course of action by the Board of Directors in respect of such conflict of interest shall be permitted and deemed approved by all Members, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty existing at law, in equity or otherwise, including any fiduciary duty, if the resolution or

50

course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of holders of a majority of the Outstanding Common Units (excluding Common Units held by interested parties), (iii) on terms no less favorable to the Company than those generally being provided to or available from unrelated third parties or (iv) fair and reasonable to the Company, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Company). The Board of Directors shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval of such resolution, and the Board of Directors may also adopt a resolution or course of action that has not received Special Approval, provided that interested directors shall recuse themselves from participation in such resolution. If Special Approval is not sought and the Board of Directors determines that the resolution or course of action taken with respect to a conflict of interest complies with the standards set forth in clause (iii) or (iv) of the second preceding sentence, then (A) such resolution or course of action shall be permitted and deemed approved by all the Members, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty existing at law, in equity or otherwise, including any fiduciary duty and (B) it shall be presumed that, in making its decision, the Board of Directors acted in good faith, and in any proceeding brought by any Member or Assignee or by or on behalf of such Member or any other Member or the Company challenging such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption. Notwithstanding anything to the contrary in this Agreement, the existence of the conflicts of interest described in the Registration Statement are hereby approved by all Members and shall not constitute a breach of this Agreement or any duty existing at law, in equity or otherwise.

(b) Whenever the Board of Directors or any Director or Officer makes a determination or takes or declines to take any other action, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then, unless another express standard is provided for in this Agreement, the Board of Directors or such Director or Officer shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. In order for a determination or other action to be in “good faith” for purposes of this Agreement, the Person or Persons making such determination or taking or declining to take other action must believe that the determination or other action is in the best interests of the Company. No action taken by the Board of Directors, any Director or any Officer on behalf of the Company in good faith reliance on the provisions of this Agreement, including thisArticle 7, shall constitute a breach of any duty (including any fiduciary duty or other similar duty) on the part of such Board of Directors or any Director or Officer, as the case may be. To the extent that the foregoing provisions have, or are construed to have, the effect of restricting, eliminating or otherwise modifying the duties and liabilities, including fiduciary duties, of the Directors or Officers otherwise existing at law, in equity or otherwise, such provisions and any such restriction, elimination or modification (i) are, and shall be deemed to have been, approved and agreed to by the Members (ii) are intended and agreed to replace and supersede such other duties and liabilities.

(d) Except as expressly set forth in this Agreement or required by law, none of the Directors, nor any other Indemnitee shall have any duties or liabilities, including fiduciary duties, to the Company or any Member and the provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of the Directors or any other Indemnitee otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of the Directors or such other Indemnitee.

(e) The Members hereby authorize the Board of Directors, on behalf of the Company as a partner or member of a Group Member, to approve of actions by the Board of Directors or managing member of such Group Member similar to those actions permitted to be taken by the Board of Directors pursuant to thisSection 7.9.

(c) the entry of a decree of judicial dissolution of the Company pursuant to the provisions of the Delaware Act; or

(d) at such time as there are no Members, unless the Company is continued without dissolution in accordance with the Delaware Act.

Section 10.2Liquidator.

Upon dissolution of the Company, the Board of Directors shall select one or more Persons to act as Liquidator. The Liquidator (if other than the Board of Directors) shall be entitled to receive such compensation for its services as may be approved by holders of a Unit Majority. The Liquidator (if other than the Board of Directors) shall agree not to resign at any time without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of a Unit Majority. Upon dissolution, death, incapacity, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of a Unit Majority. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in thisArticle 10, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the Board of Directors under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth inSection 7.3(b)) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Company as provided for herein.

54

Section 10.3Liquidation.

The Liquidator shall proceed to dispose of the assets of the Company, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as determined by the Liquidator, subject to Section 18-804 of the Delaware Act and the following:

(a) The assets may be disposed of by public or private sale or by distribution in kind to one or more Members on such terms as the Liquidator and such Member or Members may agree. If any property is distributed in kind, the Member receiving the property shall be deemed for purposes ofSection 10.3(c) to have received cash equal to its fair market value; and contemporaneously therewith, appropriate cash distributions must be made to the other Members. Notwithstanding anything to the contrary contained in this Agreement, the Members understand and acknowledge that a Member may be compelled to accept a distribution of any asset in kind from the Company despite the fact that the percentage of the asset distributed to such Member exceeds the percentage of that asset which is equal to the percentage in which such Member shares in distributions from the Company. The Liquidator may defer liquidation or distribution of the Company’s assets for a reasonable time if it determines that an immediate sale or distribution of all or some of the Company’s assets would be impractical or would cause undue loss to the Members. The Liquidator may distribute the Company’s assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Members.

(b) Liabilities of the Company include amounts owed to the Liquidator as compensation for serving in such capacity (subject to the terms ofSection 10.2) and amounts to Members otherwise than in respect of their distribution rights underArticle 6. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be applied to other liabilities or distributed as additional liquidation proceeds.

(c) All property and all cash in excess of that required to discharge liabilities as provided inSection 10.3(b) shall be distributed to the Members in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to thisSection 10.3(c)) for the taxable year of the Company during which the liquidation of the Company occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable year (or, if later, within 90 days after said date of such occurrence).

Section 10.4Cancellation of Certificate of Formation.

Upon the completion of the distribution of Company cash and property as provided inSection 10.3 in connection with the liquidation of the Company, the Certificate of Formation and all qualifications of the Company as a foreign limited liability company in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Company shall be taken.

Section 10.5Return of Contributions.

None of any member of the Board of Directors or any Officer will be personally liable for, or have any obligation to contribute or loan any monies or property to the Company to enable it to effectuate, the return of the Capital Contributions of the Members or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Company assets. A Member may not resign or withdraw from the Company prior to the dissolution and winding up of the Company, provided that the transfer of any Member Interest shall not constitute a breach or violation of this provision.

Section 10.6Waiver of Partition.

To the maximum extent permitted by law, each Member hereby waives any right to partition of the Company property.

Section 10.7Capital Account Restoration.

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

Section 11.7Waiver of Notice; Approval of Meeting.

Whenever notice to the Members is required to be given under this Agreement, a written waiver, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice.

Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Members need be specified in any written waiver of notice unless so required by resolution of the Board of Directors.

(c) At any time from and after the Purchase Date, a holder of an Outstanding Member Interest subject to purchase as provided in thisSection 13.1 may surrender his Certificate evidencing such Member Interest to the Transfer Agent in exchange for payment of the amount described inSection 13.1(a), therefor, without interest thereon.

(d) Upon the exercise by any Person of the right to purchase Member Interests granted pursuant toSection 13.1(a), no Member shall be entitled to dissenters’ rights of appraisal.
