Consistent with the provisions of Regulations Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Interests for cash or Contributed Property, the Capital Accounts 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 4.1. 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 such Interests shall be determined by the Operating Member using such method of valuation as it may adopt.

(e)Distributed Unrealized Gains and Losses. In accordance with Regulations Section 1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Member of any Company property (other than a distribution of cash or cash equivalents that are not in redemption or retirement of a Member’s Interest), the Capital Accounts of all Members and the Carrying Value of each 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 (which shall be determined by the Operating Member using any valuation method it deems reasonable under the circumstances), and had been allocated to the Members at such time, pursuant toSection 4.1.

(f)Code Compliance. The parties intend that the foregoing provisions cause each Member’s Capital Account to be maintained and adjusted in accordance with the Code and Regulations thereunder, and such provisions shall be interpreted consistently with such intent.

3.5Return of Capital. No Member shall have the right to demand a return of such Member’s Capital Contributions (or the balance of such Member’s Capital Account). Further, no Member has the right (i) to demand and receive any distribution from the Company in any form other than cash or (ii) to bring an action of partition against the Company or its property. Neither the Members nor the Management Committee shall have any personal liability for the repayment of the Capital Contributions from Members. No Member is required to contribute or to lend any cash or property to the Company to enable the Company to return any other Member’s Capital Contributions.

-23-

3.6Loans by Members. The Company may incur indebtedness only upon the approval of the Management Committee in accordance withSection 5.4. In addition, with the consent of the other Members, any Member may lend funds to the Company for such purposes as are specified in writing to, and approved by, the other Members, including for purposes of funding capital expenditures or working capital;provided, however, no Member may make such a loan as an alternative to any Capital Contribution required underSection 3.2. A loan account shall be established and maintained for such Member separate from such Member’s Capital Account and any loan made to the Company shall be credited to such loan account. Interest on all loans shall accrue at the Default Rate or at such other rate as may be approved by the Members and all advances to the Company from such loan account shall be repaid prior to any distributions to the Members pursuant toSection 4.3. A credit balance in such loan account shall constitute a liability of the Company; it shall not constitute a part of any Member’s Capital Account.

ARTICLE 4

ALLOCATIONS AND DISTRIBUTIONS

4.1Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in determining the rights of the Members among themselves, the Company’s items of income, gain, loss and deduction (computed in accordance withSection 3.4(b)) shall be allocated among the Members in each taxable year or portion thereof (an “allocation period”) as provided herein below.

(a)Net Income. All items of income, gain, loss and deduction taken into account in computing Net Income for such allocation period shall be allocated to each of the Members in accordance with its respective Percentage Interest.

(b)Net Losses. All items of income, gain, loss and deduction taken into account in computing Net Losses for such allocation period shall be allocated to each Member in accordance with its respective Percentage Interest;provided, however, that Net Losses shall not be allocated pursuant to thisSection 4.1(b)to the extent that such allocation would cause a Member to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account).

(c)Nonrecourse Liabilities. For purposes of 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 (computed without duplication of items between (A) and (B)) shall be allocated among the Members in accordance with their respective Percentage Interests.

(d)Company Minimum Gain Chargeback. Notwithstanding the other provisions of this Section 4.1, except as provided in Regulations Sections 1.704-2(f)(2) through (5), if there is a net decrease in Company Minimum Gain during any Company taxable year, each Member shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Regulations Sections 1.704-2(f)(6) and (g)(2) and Section 1.704-2(j)(2)(i), or any successor provisions. For purposes of thisSection 4.1(d), each Member’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to thisSection 4.1 with respect to such taxable year (other than an allocation pursuant toSection 4.1(h) or(i)).

-24-

(e)Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt. Notwithstanding the other provisions of thisSection 4.1 (other thanSection 4.1(d), except as provided in Regulations Section 1.704-2(i)(4)), if there is a net decrease in Minimum Gain Attributable to Member Nonrecourse Debt during any Company taxable period, any Member with a share of Minimum Gain Attributable to Member Nonrecourse Debt at the beginning of such taxable period shall be allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of thisSection 4.1, each Member’s Adjusted Capital Account balance shall be determined and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to thisSection 4.1, other thanSections 4.1(d),(h) and(i), with respect to such taxable period.

(f)Qualified Income Offset. In the event any Member unexpectedly receives adjustments, allocations or distributions described in Regulations Sections 1.704-1(b)(2)(ii)(d)(4) through (6) (or any successor provisions), items of Company income and gain shall be specifically allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the 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 4.1(d) or4.1(e).

(g)Gross Income Allocations. In the event any Member has a deficit balance in its Adjusted Capital Account at the end of any Company taxable period which is in excess of the sum of (i) the amount such Member is obligated to restore pursuant to any provisions of this Agreement and (ii) the amount such Member is deemed obligated to restore pursuant to the penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), such Member shall be specifically allocated items of Company gross income and gain in the amount of such excess as quickly as possible;provided, that an allocation pursuant to thisSection 4.1(g) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in thisSection 4.1 have been tentatively made as if thisSection 4.1(g) was not in the Agreement.

(h)Nonrecourse Deductions. Nonrecourse Deductions for any taxable year shall be allocated to the Members in accordance with their respective Percentage Interests. If the Company determines in its good faith discretion that the Company’s Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor requirements of the Regulations promulgated under Section 704(b) of the Code, the Company is authorized, upon notice to the Members, to revise the prescribed ratio to the numerically closest ratio which does satisfy such requirements.

(i)Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable year shall be allocated 100% to the Member that bears the Economic Risk of Loss for such Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Regulations Section 1.704-2(i) (or any successor provision). 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 ratably in proportion to their respective shares of such Economic Risk of Loss.

-25-

(j)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 Regulations 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 (if the adjustment increases the basis of the asset) or 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 Regulations.

(k)Special Allocations Regarding WFSG Sub Note and Retained Member Proceeds. Notwithstanding any other provision to the contrary in this Agreement, any items of income, gain, loss or expense or Unrealized Gain or Unrealized Loss related to (i) the WFSG Sub Note shall be allocated solely to the Preferred Interest Member, and (ii) Retained Member Proceeds shall be allocated to the Member with respect to which the Retained Member Proceeds are retained, but shall not be treated as items of the Company for tax or Capital Account purposes.

(l)Special Allocations Regarding Plant Matters Expenditures. Any deduction or loss attributable to costs or depreciable expenses incurred by the Company in connection with the payment of Plant Matters Expenditures by WFSG or an Affiliate (other than the Company) pursuant toSection 10.3(c) of the Formation Agreement shall be allocated solely to WFSG Sub.

4.2Allocations for Tax Purposes. The Members agree as follows:

(a)Allocations of Gain, Loss, etc. Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction which is recognized by the Company for federal income tax purposes 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 4.1 hereof.

(b)Book-Tax Disparities. In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, 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) In the case of a Contributed Property, (A) such items of income, gain, loss, depreciation, amortization and cost recovery deductions attributable thereto shall be allocated among the Members in the manner provided under Section 704(c) of the Code and Section 1.704-3(d) of the Regulations (i.e. the “remedial method”) 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 thereto shall be allocated among the Members in the same manner as is correlative item of “book” gain or loss is allocated pursuant toSection 4.1.

-26-

(ii) In the case of an Adjusted Property, (A) such items of income, gain, loss, depreciation, amortization and cost recovery deductions attributable thereto shall be allocated among the Members in a manner consistent with the principles of Section 704(c) of the Code and Section 1.704-3(d) of the Regulations (i.e. the “remedial method”) to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant toSection 3.4(d) or3.4(e), unless such property was originally a Contributed Property, in which case such items shall be allocated among the Members in a manner consistent withSection 4.2(b)(i); 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 4.1.

(c)Conventions/Allocations. For the proper administration of the Company, the Company shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; and (ii) amend the provisions of this Agreement as appropriate to reflect the proposal or promulgation of Regulations under Section 704(b) or Section 704(c) of the Code. The Company may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in thisSection 4.2(c) only if such conventions, allocations or amendments are consistent with the principles of Section 704 of the Code.

(d)Section 743(b). The Company may determine to depreciate 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) using a predetermined rate derived from the depreciation method and useful life applied to the Company’s common basis of such property, despite the inconsistency of such method with Regulations Section 1.167(c)-1(a)(6), or any successor provisions. If the Company determines that such reporting position cannot reasonably be taken, the Company may adopt any reasonable depreciation convention that would not have a material adverse effect on the Members.

(e)Recapture Income. 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 4.2 be characterized as Recapture Income in the same proportions and 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.

(f)Section 754. 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 which may be made by the Company;provided, however, that such allocations, once made, shall be adjusted as necessary or appropriate to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

4.3Distributions.

(a) Subject toSection 4.3(b) andSection 9.2, within 30 days following the end of each Distribution Period, an amount equal to 100% of Available Cash with respect to such Distribution Period shall, subject to Section 18-607 of the Delaware Act, be distributed in accordance with thisArticle 4 by the Company to the Members in accordance with their respective Percentage Interests (at the time the amount of such distributions are made).

-27-

(b) Prior to any distribution made pursuant toSection 4.3(a), a Member shall be entitled upon giving written notice to the Company to have such Member’s Percentage Interest of Available Cash subject to such distribution deposited into an interest bearing account of the Company for the benefit only of such Member (the “Retained Member Proceeds”). Such account shall be a separate Company account maintained for such Member and no proceeds in such account shall be commingled with any other proceeds or accounts of the Company or of any other Member.

(c) From time to time and at any time, upon the delivery of written notice to the Company by the relevant Member, such Member may either (i) direct the Company to distribute all or any portion of such Member’s Retained Member Proceeds (and any interest with respect to such Retained Member Proceeds) to such Member, in which event the Company shall promptly distribute such portion of the Retained Member Proceeds (and any interest with respect to such Retained Member Proceeds) to such Member as directed, or (ii) direct the Company to apply all or any portion of such Member’s Retained Member Proceeds (and any interest with respect to such Retained Member Proceeds) against any obligation of the Member to make a Capital Contribution pursuant to the terms of this Agreement, in which event such portion of the Retained Member Proceeds (and any interest with respect to such Retained Member Proceeds) shall be deemed to have been made as a Capital Contribution to the Company by such Member.

4.4Preferred Distribution Rights.

(a) Notwithstanding any provision in this Agreement to the contrary, any payments of principal or interest under the WFSG Sub Note (“Note Income”) shall (unless otherwise directed pursuant toSection 3.2(c)) be distributed solely to APL Sub (referred from time to time in this Agreement as the “Preferred Interest Member”) in accordance withSection 4.4(b) (the “Preferred Distribution Rights”).

(b) Notwithstanding any provision in this Agreement to the contrary, if and to the extent that the Company receives Note Income, then the Company shall promptly make a distribution to the Preferred Interest Member in an amount equal to 100% of any such Note Income. Except as set forth inSection 9.2(c)(v) of this Agreement, such distribution shall be unconditionally made without right of recoupment or setoff.

(c) Except for distributions made in violation of the Delaware Act or other applicable Law, the Preferred Interest Member shall not be obligated to return any distribution of Note Income to the Company or pay the amount of any such distribution for the account of the Company or to any creditor of the Company. The amount of any such distribution returned to the Company by the Preferred Interest Member or paid by the Preferred Interest Member for the account of the Company or to a creditor of the Company shall be added to the account or accounts from which it was subtracted when it was distributed to the Preferred Interest Member.

-28-

4.5Varying Interests. All items of income, gain, loss, deduction or credit shall be allocated, and all distributions shall be made, to the Persons shown on the records of the Company to have been Members as of the last calendar day of the period for which the allocation or distribution is to be made. Notwithstanding the foregoing, if during any taxable year there is a change in any Member’s Percentage Interest, the Members agree that their allocable shares of items for the taxable year shall be determined by the Tax Matters Member using an interim closing of the books under Code Section 706 and the related Treasury Regulations to take account of the Members’ varying Percentage Interests.

ARTICLE 6

INDEMNIFICATION; LIMITATIONS ON LIABILITY

6.1 Indemnification by the Company.

(a)Indemnification. The Company shall indemnify and hold harmless each Member, each Representative, the alternates of each Representative, and the officers of the Company (each individually, a “Company Indemnitee”) from and against any and all losses, claims, demands, costs, damages, liabilities, expenses of any nature (including reasonable attorneys’ fees and disbursements), judgments, fines, settlements, and other amounts actually and reasonably incurred by such Company Indemnitee and arising from any threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative or other, including any appeals, to which a Company Indemnitee was or is a party or is threatened to be made a party (collectively, “Liabilities”), arising out of or incidental to the business of the Company or such Company Indemnitee’s status as a Member, Representative or alternate of a Representative or an officer of the Company;provided, however, that the Company shall not indemnify and hold harmless any Company Indemnitee for any Liabilities which are due to actual fraud or willful misconduct of such Company Indemnitee.

(b)Rights of Company Indemnitee. Reasonable expenses incurred by a Company Indemnitee in defending any claim, demand, action, suit or proceeding subject to thisSection 6.1 shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of such Company Indemnitee to repay such amounts if it is ultimately determined that such Company Indemnitee is not entitled to be indemnified as authorized in thisSection 6.1. The indemnification provided by thisSection 6.1 shall inure solely to the benefit of the Company Indemnitee and his heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

6.2 Indemnification by the Members. Each Member shall indemnify and hold harmless the Company, the other Members and their respective Representatives and alternates and the officers of the Company (each individually, a “Member Indemnitee”) for any and all Liabilities actually and reasonably incurred by such Member Indemnitee solely as a result of the actual fraud or willful misconduct of such Member, its Representatives and alternates or any officer of the Company employed by such Member or its Affiliates.

6.3 Defense of Action. Promptly after receipt by a Company Indemnitee or a Member Indemnitee (either, an “Indemnified Party”) of notice of any pending or threatened claim, demand, action, suit, proceeding or investigation made or instituted by a Person other than another Indemnified Party (a “Third Party Action”), such Indemnified Party shall, if a claim in respect thereof is to be made by such Indemnified Party against a Person providing indemnification pursuant toSections 6.1 or6.2 (“Indemnifying Party”), give notice thereof to the Indemnifying Party. The Indemnifying party, at its own expense, may elect to assume the defense of any such Third Party Action through its own counsel on behalf of the Indemnified Party (with full right of subrogation to the Indemnified Party’s rights and defenses). The Indemnified Party may employ separate counsel in any such Third Party Action and participate in the defense thereof; but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless the

-32-

Indemnified Party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party shall not have the right to assume the defense of such Third Party Action on behalf of the Indemnified Party), it being understood, however, that the Indemnifying Party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the Indemnified Parties, and such fees shall be designated in writing by the Indemnified Parties. All fees and expenses for any such separate counsel shall be paid periodically as incurred. The Indemnifying Party shall not be liable for any settlement of any such Third Party Action effected without its consent unless the Indemnifying Party shall elect in writing not to assume the defense thereof or fails to prosecute diligently such defense and fails after written notice from the Indemnified Party to promptly remedy the same, in which case, the Indemnified Party without waiving any rights to indemnification hereunder may defend such Third Party Action and enter into any good faith settlement thereof without the prior written consent from the Indemnifying Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, effect any settlement of any such Third Party Action unless such settlement includes an unconditional release of the Indemnified Party from all Liabilities that are the subject of such Third Party Action. The Members agree to cooperate in any defense or settlement of any such Third Party Action and to give each other reasonable access to all information relevant thereto. The Members will similarly cooperate in the prosecution of any claim or lawsuit against any third party. If, after the Indemnifying Party elects to assume the defense of a Third Party Action, it is determined pursuant to the dispute resolution procedures described inSection 13.11 that the Indemnified Party is not entitled to indemnification with respect thereto, the Indemnifying Party shall discontinue the defense thereof, and if any fees or expenses for separate counsel to represent the Indemnified Party were paid by the Indemnifying Party, the Indemnified Party shall promptly reimburse the Indemnifying Party for the full amount thereof.

6.4 Limited Liability of Members. To the fullest extent permitted by applicable Law, no Member shall be personally liable for any debts, liabilities or obligations of the Company;provided, that each Member shall be responsible (i) for the making of any Capital Contribution required to be made to the Company by such Member pursuant to the terms hereof and (ii) for the amount of any distribution made to such Member that must be returned to the Company pursuant to the Delaware Act.

6.5 Waiver of Duties.

(a) Each Member acknowledges its express intent, and agrees with the other Member, for the benefit of the Representatives, that to the fullest extent permitted by applicable Law: (i) the only fiduciary or other duties or obligations, if any, that any Representative will owe in their capacity as a Representative will be to the Member that appointed such Representative to serve in that capacity, and the nature and extent of those duties and obligations and the liabilities resulting from any breach thereof constitute an internal governance affair of Member; and (ii) no Representative will, under this Agreement, the Delaware Act or otherwise, owe in his capacity as a Representative, or be personally liable for monetary damages for any breach of, any fiduciary or other duties or obligations, including any obligation of good faith and fair dealing, to the Company, any other Member or any of their respective Affiliates or any other Representative.

Any action taken (or authorized) by the Operating Member shall not require any further action, approval or consent of the Members or the Management Committee, except solely to the extent provided underSection 5.4 or as otherwise expressly provided in this Agreement. To the extent that any action requiring authorization by the Management Committee is approved in accordance with the provisions ofSection 5.4, the Operating Member shall be deemed to be authorized to take such actions as may be necessary (or which the Operating Member, in its good faith believes is required) to implement or carry out the intent of the Management Committee relative to such authorized actions. The Management Committee may from time to time re-determine the authority delegated to the Operating Member pursuant to thisSection 7.1 by a unanimous resolution of the Representatives, and without any further requirement to amend or modify this Agreement.

7.2 Expenses.

(a) The Operating Member shall be reimbursed for all direct charges incurred or payments actually made by the Operating Member, acting in such capacity (including amounts paid to Affiliates of the Operating Member), to the extent such charges are included in the amounts in any approved Operating Budget, approved Growth Capital Budget or other approved Growth Capital Expenditures (the “Direct Charges”).

-35-

(b) As reimbursement for all expenses other than Direct Charges allocable to the Company or otherwise incurred by a Member in connection with the discharge of duties under this Agreement in connection with the operations of the Company, the Company shall pay the Operating Member a monthly rate of $133,000 (the “Operating Fee”) for the balance of calendar year 2009 and prorated for any partial month, which amount shall be paid each month beginning on the first day of the first month after the Closing Date. The Operating Fee shall be netted against any amounts paid to Atlas America (or its Affiliate) pursuant to the Transition Services Agreement. Unless otherwise adjusted by the Management Committee following its evaluation of the Operating Fee in connection with the Operating Budget approval cycle, the Operating Fee will be increased to a rate of $2.2 million annually for the year beginning January 1, 2010, which amount shall be paid in twelve equal monthly payments beginning on January 1, 2010.

(c) Commencing with January 1, 2012, the Operating Fee shall be adjusted every other year as of the first day of January of such alternate year in connection with the Operating Budget approval cycle, and such amounts shall continue to be payable by the Company during each year in twelve equal monthly payments beginning on January 1 of each year;provided,however, that any such adjustment shall require the unanimous approval of the Management Committee. If the Management Committee fails to approve an adjustment in the Operating Fee in accordance with the terms of thisSection 7.2(c), then the Operating Fee shall be adjusted as of the first day of January of such alternate year for which the Management Committee fails to approve any such adjustment by multiplying the Operating Fee currently in use by the percentage increase or decrease, if any, in the GDPCP Index over the prior year for which information is then available by each year. This percentage adjustment shall be calculated based upon the most recent quarterly publication of the GDPCP Index published and available and shall be compared to the quarterly publication of the GDPCP Index for the same quarter of the prior calendar year. If the GDPCP Index ceases to be published, then it shall be replaced with the IPD Index. If both the GDPCP Index and the IPD Index cease to be published, then the Management Committee shall within thirty (30) days of written notice thereof from the Operating Member negotiate a replacement index. The adjusted Operating Fee shall be the Operating Fee currently in use, plus or minus the computed adjustment.

(d) In connection with the Operating Budget approval cycle, the Operating Member shall be entitled to request an increase in the Operating Fee.

(e) In the event the Non-Operating Member becomes the Operating Member pursuant toSection 7.5, the new Operating Member shall from that time forward be entitled to receive the Operating Fee.

(f) All amounts due to the Operating Member under thisSection 7.2 shall be paid within 25 days of Operating Member’s monthly invoice.

7.3 Accounts and Other Matters

(a)Accounts. The Operating Member shall establish and maintain one or more separate bank and investment accounts and arrangements for Company funds in the Company’s name with such financial institutions and firms it may determine. The Company may not commingle the Company’s funds with the funds of any Member or any other Person. All such accounts shall be and remain the property of the Company and all funds shall be received, held and disbursed for the purposes specified in this Agreement.

-36-

(b)Certain Additional Undertakings.

(i)Separateness Generally. The Operating Member shall cause the Company to conduct its business and operations in accordance with thisSection 7.3(b).

(iii)Separate Assets. The Operating Member shall cause the Company to not commingle or pool the Company’s funds or other assets with those of any other Person, and to maintain its assets in a manner that is not costly or difficult to segregate, ascertain or otherwise identify as separate from those of any other Person.

(iv)No Effect. Failure by the Operating Member or the Company to comply with any of the obligations set forth above shall not affect the status of the Company as a separate legal entity, with its separate assets and separate liabilities or restrict or limit the Company from engaging or contracting with any Member or any of their Affiliates for the provision of services or the purchase or sale of products.

7.4 Practices of the Operating Member. The Operating Member shall exercise the Operating Member’s powers and rights, and discharge the Operating Member’s duties under this Agreement in accordance with the following: (a) the requirements of this Agreement; (b) in accordance with practices generally acceptable for an experienced and prudent operator engaged in a similar activity under similar circumstances of the natural gas gathering industry; (c) all applicable Laws and regulations, including environmental standards in effect from time to time, and any other applicable rules and requirements of Governmental Authorities; (d) the contractual obligations and undertakings of the Company, as the same may be amended from time to time; and (e) honestly, in good faith and in the reasonable interests of the Company;provided, however, that in the event of a conflict among any of the foregoing, the most stringent requirement on the Operating Member shall prevail; and provided, further, that the Operating Member shall not deemed to be in breach of thisSection 7.4 if, with respect toclauses (c) and(d)only, the Operating Member commits any nonmaterial violation or default that does not adversely affect the Company in a material manner.

-37-

7.5 Replacement of the Operating Member. If WFSG Sub (a) as Operating Member is in Default pursuant toSection 9.1 or (b) ceases to hold a Percentage Interest of at least 34%, then APL Sub, as long as it is not in Default under this Agreement, shall become the Operating Member and assume all the rights and responsibilities of the Operating Member provided for in this Agreement;provided, however, that nothing in thisSection 7.5 shall be deemed to affect the rights of the former Operating Member as a Member under this Agreement.

ARTICLE 8

TRANSFER AND ISSUANCE OF INTERESTS

8.1 Restrictions on Transfer. The Members agree as follows:

(a)General. Except as provided in thisArticle 8, a Member may not sell, assign, transfer, convey, merge, consolidate, reorganize, exchange or otherwise dispose, directly or indirectly (through the sale of equity interests in a direct or indirect parent entity or otherwise), whether voluntary or involuntary or by operation of Law (“Transfer”), all or any part of such Member’s Interest;provided, that the foregoing restriction shall not preclude or limit a Member’s ability to mortgage, pledge, encumber or create or suffer to exist any pledge, lien, charge or encumbrance upon, security interest or participation in, or trust in respect of all or any part of such Member’s Interest. Any attempted Transfer of an Interest, other than in strict accordance with thisArticle 8, shall be, and is hereby declared, null and voidab initio. The rights and obligations constituting an Interest may not be separated, divided or split from the other attributes of an Interest except as contemplated by the express provisions of this Agreement. The Members agree that a breach of the provisions of thisArticle 8 may cause irreparable injury to the Company and to the other Members for which monetary damages (or other remedy at law) are inadequate in view of (i) the complexities and uncertainties in measuring the actual damages that would be sustained by reason of the failure of a Member to comply with such provision and (ii) the uniqueness of the Company’s business and the relationship among the Members. Accordingly, the Members agree that the provisions of thisArticle 8 may be enforced by specific performance pursuant toSection 13.11.

(b)Certain Prohibited Transfers. No Member shall Transfer all or any part of its Interest if such Transfer (i) (either considered alone or in the aggregate with prior Transfers by the same Member or any other Member) would result in the termination of the Company for federal income tax purposes; (ii) would result in a violation of the Delaware Act or any other applicable Laws; or (iii) would result in a Default hereunder or termination of an existing financial agreement to which the Company is a party or in the acceleration of debt thereunder.

(c)Defaulting Members. No Defaulting Member may Transfer any of its Interest except with the consent of the Non-Defaulting Member and subject toSection 9.2(a).

-38-

8.2 Possible Additional Restrictions on Transfer

(a)General Restriction. Except as provided inSection 8.2(b) below, a Member may not Transfer all or any part of such Member’s Interest except by complying with all of the following requirements: (i) such Transfer occurs after the earlier of (x) the fifth anniversary of the date of this Agreement and (y) such time as the WFSG Sub Note is retired, subject toSection 8.1;provided, however, that under no circumstances (other than as provided inSection 8.2(b)) may such Transfer occur before the second anniversary of the date of this Agreement; (ii) such Member must obtain the express written consent of the other Member, which consent may be granted or withheld by any such other Member in its absolute discretion, except as permitted underSection 8.2(d); and (iii) such Member must offer such other Member the right to acquire such Interest in accordance withSection 8.2(d).

(b)Permitted Transfers. Upon written notice to the other Member and without triggering any rights underSection 8.2(d) or requiring the consent of such other Member, a Member may Transfer all or any part of its respective Interest, subject toSection 8.1(b) (other thanSection 8.1(b)(i)) andSection 8.1(c), as follows (each, a “Permitted Transfer”):

(i) any Transfer to a Related-Party Parent of such Member or one or more Persons wholly owned or controlled directly or indirectly by such Related-Party Parent;

(ii) any Transfer to any Person that is controlled by the Member or a Related-Party Parent of such Member;provided,however, that (A) such Transfer may only be made indirectly to such Person, (B) neither such Person nor any member of such Person’s consolidated group for financial accounting purposes is primarily engaged in one or more of the following businesses, the exploration, production, gathering and transportation of hydrocarbons or the processing of natural gas and (C) such Person is not listed onSchedule 8.2(b) hereto;

(iii) any Transfer to one or more Persons in connection with the Transfer of any assets, including equity securities, in which (A) the Member’s entire Interest is being transferred and (B) such Interest does not represent more than 15% of the fair market value of the assets being transferred concurrently by the Parent of such Member;

(iv) any Transfer resulting from any issuance, sale or other transfer of equity by any Related-Party Parent of a Member, whether by merger, consolidation or otherwise; or

(v) any Transfer resulting from the sale of all or substantially all of the assets of a Member’s Parent.

Notwithstanding the foregoing, no Transfer of WFSG Sub’s Interest to a Related-Party Parent or wholly owned subsidiary thereof shall be a Permitted Transfer unless WFSG Sub concurrently assigns the WFSG Sub Note to such Related-Party Parent or subsidiary thereof.

(c)Possible Additional Restrictions on Transfer. Notwithstanding anything to the contrary contained in this Agreement, in the event of (i) the enactment (or imminent enactment) of any legislation, (ii) the publication of any temporary or final Regulation, (iii) any ruling by the Internal Revenue Service or (iv) any judicial decision that in any such case, in the opinion of counsel, would result in the taxation of the Company for federal income tax purposes as a corporation or would otherwise subject the Company to being taxed as an entity for federal income tax purposes, this Agreement shall be deemed to impose such restrictions on the Transfer

-39-

of a Member’s Interest as may be required, in the opinion of counsel to the Company, to prevent the Company from being taxed as a corporation or otherwise being taxed as an entity for federal income tax purposes, and the Members thereafter shall amend this Agreement as necessary or appropriate to impose such restrictions.

(d)Right of First Refusal

(i)Procedure. If a Member at any time desires to consummate a bona fide transaction that will result in the Transfer of all or a portion of its Interest (whether or not the proposed Transfer is to another Member), then such Member (the “Offering Member”) shall promptly give notice thereof (the “Offer Notice”) to the Company and the other Members;provided, however, that thisSection 8.2(d)(i) shall not apply to a Permitted Transfer. The Offer Notice shall set forth all relevant information with respect to the proposed Transfer, including the name and address of the prospective acquirer, the precise Interest that is the subject of the Transfer (the “Marketed Interest”), the price to be paid for such Marketed Interest and any other terms and conditions of the proposed Transfer, including an execution copy of the agreement pursuant to which the proposed Transfer is to take place (the “Proposed Transfer Agreement”). The other Member (the “Non-Offering Member”) shall have the right of first refusal (“Right of First Refusal”) to acquire, for the same purchase price, as set forth in the Offer Notice, and on terms and provisions that are not less favorable to the Offering Member than the terms and provisions contained in the Proposed Transfer Agreement, such Marketed Interest;provided,further, that if the purchase price to be paid to the Offering Member pursuant to the proposed Transfer is not entirely in cash, the purchase price for the Non-Offering Member shall be the sum of (A) the cash portion of the purchase price, (B) in the case of any marketable securities constituting part of such purchase price, the volume-weighted average closing price of any such marketable securities over the 20 trading days immediately preceding the date of the Offer Notice, and (C) in the case of any part of the purchase price not constituting cash or marketable securities, the fair market value of such part of the purchase price determined in good faith by the Management Committee. The Non-Offering Member shall have the right (but not the obligation) to acquire the Marketed Interest. If the Non-Offering Member wishes to exercise the Right of First Refusal, the Non-Offering Member must provide notice of its election (the “Election Notice”), to the Offering Member within 30 days of receipt by the Non-Offering Member of the Offer Notice (the “Election Period”), or the Non-Offering Member shall be deemed to have waived its Right of First Refusal for the subject Transfer, but not any Right of First Refusal for future Transfers. Upon receipt of the Election Notice by the Offering Member, the Members shall negotiate in good faith and enter into a definitive agreement with respect to the transaction specified by the Non-Offering Member in the Election Notice and consummate such transaction within 90 days of receipt of the Offer Notice by the Non-Offering Member. If the Members do not consummate the transaction specified in the Election Notice within such 90-day period, the Non-Offering Member shall be deemed to have waived its Right of First Refusal.

(ii)Waiver of Right of First Refusal. If the Right of First Refusal is deemed waived pursuant toSection 8.2(d)(i), the Offering Member shall have the right, subject to compliance with the provisions ofSections 8.1 and8.2, to market, offer, negotiate and consummate the Transfer of the Marketed Interest described in the Offer Notice to a third party for a period of 120 days after the expiration of the Election Period;provided, however, that the Offering Member may not consummate any such Transfer to a third

-40-

party unless (x) the acquisition consideration to be paid by such third party is at least equal in value to the consideration set forth in the Offer Notice and (y) the other terms and provisions of such sale are substantially identical to, and not more favorable to such third party than, the terms and provisions contained in the Proposed Transfer Agreement. If, however, the Offering Member is unable to consummate the Transfer of the Marketed Interest to a third party within the 120-day period following expiration of the Election Period, the proposed Transfer shall again become subject to the Right of First Refusal inSection 8.2(d)(i).

(iii)Applicability of Transfer Restrictions. All transfers pursuant to thisSection 8.2(d) must comply with the restrictions on transfers set forth inSection 8.1 (other thanSection 8.1(b)(i)) andSection 8.2.

8.3Restriction on Preferred Distribution Rights. Notwithstanding any provision in this Agreement to the contrary, the Preferred Distribution Rights and any other rights expressly designated in this Agreement as being rights of the Preferred Interest Member shall not be Transferred by the Preferred Interest Member.

8.4Documentation; Validity of Transfer. No purported transfer of a Member’s Interest shall be effective as to the Company or the other Members unless and until the applicable provisions ofSections 8.1 and8.2 have been satisfied and such other Members have received a document in a form acceptable to such other Members executed by both the transferring Member (or its legal representative) and the transferee. Such document shall include: (i) the notice address of the transferee, (ii) such transferee’s express agreement in writing to be bound by all of the terms and conditions of this Agreement with respect to the Interest being transferred, (iii) the Interests of the transferring Member and the transferee after the transfer and (iv) representations and warranties from both the transferring Member and the transferee that the transfer was made in accordance with applicable Law (including state and federal securities Laws) and the terms and conditions of this Agreement. Each transfer shall be effective against the Company and the other Members as of the first Business Day of the calendar month immediately succeeding the Company’s receipt of the document required by thisSection 8.4, and the applicable requirements ofSections 8.1 and8.2 have been met. A transferee of an Interest shall only the right to receive its Percentage Interest of the Company’s profits, losses, allocations and distributions until such time as such transferee is admitted as a substituted Member pursuant toSection 8.5.

8.5Substituted Members. Upon compliance with the provisions ofSection 8.4, as of the effectiveness of any transfer of an Interest permitted under this Agreement, (i) any transferee acquiring the Interest of a Member shall be deemed admitted as a substituted Member with respect to the Interest transferred, and (ii) such substituted Member shall be entitled to the rights and powers and subject to the restrictions and liabilities of the transferring Member with respect to the Interest so acquired;provided, that no purported transfer of an Interest in violation of the terms of this Agreement (including any transfer occurring by operation of Law) shall vest the transferee with any rights, powers or privileges hereunder, and no such purported transferee shall be deemed a Member hereunder for any purposes or have any right to vote or consent with respect to Company matters, to inspect Company records, to maintain derivative proceedings, to maintain any action for an accounting or to exercise any other rights of a Member hereunder or under the Delaware Act.

-41-

8.6Covenant Not to Withdraw or Dissolve. Notwithstanding any provision of the Delaware Act, each Member hereby agrees that it has entered into this Agreement based on the expectation that all Members will continue as Members and carry out the duties and obligations undertaken by them hereunder. Except as otherwise expressly required or permitted hereby, each Member hereunder covenants and agrees not to (i) take any action to file a certificate of dissolution or its equivalent with respect to itself, (ii) take any action that would cause a Bankruptcy of such Member, (iii) withdraw or attempt to withdraw from the Company, except as otherwise expressly permitted by this Agreement or the Delaware Act, (iv) exercise any power under the Delaware Act to dissolve the Company, (v) transfer all or any portion of its Interest, except as expressly provided herein, or (vi) demand a return of such Member’s Capital Contributions or profits (or a bond or other security for the return of such contributions or profits), in each case without the consent of the other Members.

ARTICLE 9

then a “Default” hereunder shall be deemed to have occurred and the Member with respect to which one or more Events of Default has occurred shall be referred to as the “Defaulting Member,” and the other Members shall be referred to as “Non-Defaulting Members.”

9.2Consequences of Default. The Members agree as follows:

(a)Forfeiture of Rights. Notwithstanding anything contained herein to the contrary, a Defaulting Member who is in default pursuant toSections 9.1(a) or9.1(b) shall forfeit all rights as a Member, including all rights underArticle 5, other than the right to receive its Percentage Interest of the Company’s profits, losses, allocations and distributions.

(c)Options of Non-Defaulting Members. In the event of the occurrence of an Event of Default, the Non-Defaulting Member may take one or more of the following actions:

(i) cure the Default and cause the cost of such cure to be charged against a special loan account established for the Defaulting Member until the entire amount of such cost plus interest at the Default Rate on the unpaid balance in accordance withSection 3.2 shall have been recovered by the Non-Defaulting Member from any subsequent distributions made pursuant to this Agreement to which the Defaulting Member would otherwise have been entitled, which amounts shall be paid first as interest and then principal, until the cost is paid in full;

-43-

(ii) exercise any other rights and remedies available at law or in equity, subject toSection 13.11;

(iii) in the case of a Default underSection 9.1(c)(v), WFSG Sub shall have (A) the option of recouping all or a portion of the amounts reimbursable or indemnified under the Formation Agreement by reducing the principal amount on the WFSG Sub Note pursuant to section 1.4.2 thereof or (B) the right to withhold or deduct all or a portion of the amounts reimbursable or indemnified under the Formation Agreement from one or more interest payments that would otherwise be made to the payee under the WFSG Sub Note pursuant to section 1.2 thereof;provided, that in each case, prior to exercise of such option for recoupment or right of setoff, WFSG Sub shall deliver or cause to be delivered written notice to APL Sub at least 15 days prior to the date on which WFSG Sub intends to exercise such option or right; and,provided, further, that if it is later finally determined and nonappealable that WPZ Sub (or its Affiliate) was not entitled to any portion of the Indemnity Claim Amount subject to such recoupment or setoff, WFSG Sub shall promptly reimburse APL Sub (or cause APL Sub to be reimbursed) the amount of such portion to which it was not entitled plus annualized interest on such amount at the Default Rate from the date of such recoupment or setoff to the date of reimbursement to APL Sub;provided,further, the Members agree that no pre-judgment interest or similar interest, which otherwise may be available under statutory or common law, will be payable on such reimbursed amounts.

(iv) in the case of a Default underSection 9.1(c)(v), and the amounts reimbursable or indemnified under the Formation Agreement exceed the outstanding principal amount on the WFSG Sub Note (as a result of reductions in such principal amount pursuant toSection 9.2(c)(iii)) or if the remedies underSection 9.2(c)(iii) are otherwise not available (other than as a consequence of the repayment of the WFSG Sub Note except for mandatory pre-payments underSection 3.2(c)), WFSG Sub shall also have the option (a “Default Adjustment Option”) to adjust the Capital Account of APL Sub (and of any Affiliate of APL Sub that is also a Member) downward by the amount of any such past due indemnity or reimbursement payments (a “Default Adjustment”);provided, however, that WFSG Sub shall only have the right to exercise the Default Adjustment Option if (A) the relevant indemnification claim is made prior to the expiration of the applicable survival period under the Formation Agreement and (B) WFSG Sub has delivered written notice to APL Sub at least 15 days prior to the date upon which WFSG Sub intends to exercise such Default Adjustment Option.

-45-

referred to as the “Liquidator”) shall proceed to wind up the business and affairs of the Company in accordance with the terms hereof and the requirements of the Delaware Act. A reasonable amount of time shall be allowed for the period of winding up in light of prevailing market conditions and so as to avoid undue loss in connection with any sale of Company Assets. This Agreement shall remain in full force and effect during the period of winding up.

(b)Distributions. In connection with the winding up of the Company, the Company Assets or proceeds thereof shall be distributed as follows:

(i) to the Preferred Interest Member, the WFSG Sub Note (and any guaranty thereunder) shall be distributed in-kind in satisfaction of the Preferred Interest Member’s Preferred Distribution Rights to the extent any obligation under the WFSG Sub Note remains unsatisfied and no adjustment to the Capital Accounts shall result from such distribution of the WFSG Sub Note;

(ii) to creditors, including Members who are creditors, to the extent otherwise permitted by Law, in satisfaction of liabilities of the Company (whether by payment or the making of reasonable provision for payment thereof) other than liabilities for which reasonable provision for payment has been made and liabilities to Members and former Members under Sections 18-601 and 18-604 of the Delaware Act;

(B) with respect to all Company Assets that have not been sold, the fair market value of such Company Assets (as determined by the Liquidator using any method of valuation as it, using its best judgment, deems reasonable) shall be determined and the Capital Accounts of the Members shall be adjusted in accordance withArticle 4 to reflect the manner in which the unrealized income, gain, loss, and deduction inherent in such Company Assets that have not been reflected in the Capital Accounts previously would be allocated among the Members if there were a taxable disposition of such Company Assets for their fair market value on the date of distribution;

(C) Company Assets shall be distributed among the Members ratably (provided, that Retained Member Proceeds (and any interest with respect to such Retained Member Proceeds) shall be distributed to the Member with respect to which such Retained Member Proceeds were retained), in proportion to each Member’s positive Capital Account balances, as determined after taking into account all Capital Account adjustments for the taxable year of the Company during which the liquidation of the Company occurs (other than those made by reason of thisclause (C)); and in each case, those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 days after the date of the liquidation); and

Following the completion of the winding up of the affairs of the Company and the distribution of Company Assets, the Company shall be deemed terminated and the Liquidator shall file a certificate of cancellation in the Office of the Secretary of State of the State of Delaware as required by the Delaware Act.

(a)Scope. Any dispute (other than voting dead-locks) arising out of or relating to this Agreement shall be resolved in accordance with the procedures specified in thisSection 13.11, which shall be the sole and exclusive procedures for the resolution of any such disputes.

(b)Senior Party Negotiation.

The Members shall meet within ten Business Days of the commencement of the arbitration procedures by any Member and agree on three arbitrators to act as the arbitration panel on such matters. If the Members are unable to agree at such a meeting to all three arbitrators, the panel will be appointed in the following manner.

Each party is required to continue to perform its obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement, unless to do so would be impossible or impracticable under the circumstances. The requirements of thisSection 13.11 shall not be deemed a waiver of any right of termination under this Agreement.

13.12 Disclosure. Each Member is acquiring its Interest in the Company based upon its own independent investigation, and the exercise by such Member of its rights and the performance of its obligations under this Agreement are based upon its own investigation, analysis and expertise.

13.13 Brokers and Finder.

13.14 Further Assurances. The Members shall provide to each other such information with respect to the transactions contemplated hereby as may be reasonably requested and shall execute and deliver to each other such further documents and take such further action as may be reasonably requested by any Member to document, complete or give full effect to the terms and provisions of this Agreement and the transactions contemplated herein.

13.17 Security. Each Interest shall constitute a “security” within the meaning of, and shall be governed by, (i) Article 8 of the Uniform Commercial Code (including Section 8-102(a)(15) thereof) as in effect from time to time in the State of Delaware, and (ii) Article 8 of the Uniform Commercial Code of any other applicable jurisdiction that now or hereafter substantially includes the 1994 revisions toArticle 8 thereof as adopted by the American Law Institute and the National Conference of Commissioners on Uniform State Laws and approved by the American Bar Association on February 14, 1995. Notwithstanding any provision of this Agreement to the contrary, to the extent that any provision of this Agreement is inconsistent with any non-waivable provision ofArticle 8 of the Uniform Commercial Code as in effect in the State of Delaware (6 Del.
