(a)    As of the Closing Date, the Participating Interests of the Parties are as follows:

(b)    If a Party Transfers all or any undivided percentage of its Joint Development Interest pursuant to the provisions of this Agreement, the Participating Interests of the Parties shall be revised accordingly.

2.3    Operations; Development Area.

  

(a)    Subject to Sections 2.3(c), 2.3(d), 2.5 and 2.6 and the other terms of this Agreement, CONSOL Operator shall manage and control the participation of the Parties in all Development Operations and Area-Wide Operations relating to the portion of the Development Area described on Exhibit A-2 (as adjusted pursuant to Section 2.3(c), the “CNX Operated Area”) in accordance with the Development Plan and applicable Annual Plan and Budget and such other operating guidelines as the Joint Development Committee may establish, including proposing all Development Operations on behalf of the Parties under any Applicable Operating Agreement relating to such area, making all elections on behalf of the Parties under any Applicable Operating Agreement (other than elections with respect to operations proposed by a Third Party Operator or other Third Party under an Applicable Operating Agreement) relating to such area, and conducting all Area-Wide Operations on behalf of the Parties relating to such area. In addition, subject to Sections 2.5 and 2.6, CONSOL Operator shall have such other powers and responsibilities as are set forth in this Agreement or as granted to it by the Joint Development Committee.

(b)    Subject to Sections 2.3(c), 2.3(d), 2.5 and 2.6 and the other terms of this Agreement, Noble Operator shall manage and control the participation of the Parties in all Development Operations and Area-Wide Operations relating to the portion of the Development Area described on Exhibit A-3 (as adjusted pursuant to Section 2.3(c), the “NBL Operated Area”) in accordance with the Development Plan and applicable Annual Plan and Budget and such other operating guidelines as the Joint Development Committee may establish, including proposing all Development Operations on behalf of the Parties under any Applicable Operating Agreement relating to such area, making all elections on behalf of the Parties under any Applicable Operating Agreement (other than elections with respect to operations proposed by a Third Party Operator or other Third Party under an Applicable Operating Agreement) relating to such area, and conducting all Area-Wide Operations on behalf of the Parties relating to such area. In addition, subject to Sections 2.5 and 2.6, Noble Operator shall have such other powers and responsibilities as are set forth in this Agreement or as granted to it by the Joint Development Committee.

(c)    CONSOL and Noble may adjust the allocation of the Operated Areas between the Party Operators by written agreement; provided that, at any time that Drilling Units have been designated covering at least 60% of the net acreage included in the Subject Assets within the NBL Operated Area and such Subject

Assets covered by such Drilling Units have become or, within the following 24-months months are reasonably expected to become, Developed Assets or P&A/Condemned Assets, then upon written request from Noble to CONSOL (an “Expansion Request”), Noble and CONSOL shall meet (which meeting shall occur within 15 days of such request being received by CONSOL) and use their commercially reasonable efforts to agree upon expanding the NBL Operated Area (and, if applicable, reducing the CNX Operated Area) so that Noble Operator can continue conducting drilling and completion Development Operations to the same extent and at the same pace that it was conducting drilling and completion Development Operations prior to the Expansion Request. If Noble and CONSOL are unable to so mutually agree upon an expansion of the NBL Operated Area within 45 days of CONSOL receiving an Expansion Request, then the NBL Operated Area shall automatically be expanded by one county (each, an “Expansion County”), which Expansion County shall be selected by Noble by choosing one of the counties listed on Schedule 2.3(c) that is not then a part of the NBL Operated Area (and, if applicable, the CNX Operated Area shall be reduced by excluding from such area such Expansion County, provided that, notwithstanding the foregoing, from and after the date of such expansion, the CNX Operated Area shall continue to include (and the NBL Operated Area shall not include) any Drilling Units within the Expansion County that were designated by CONSOL Operator prior to such expansion and on which any drilling and completion operations had been commenced or are reasonably expected to be commenced within six months following such expansion (the “Excluded Units”). Unless otherwise agreed by the Parties, an Excluded Unit shall cease to be an Excluded Unit and operatorship of such Excluded Unit shall be transferred to Noble Operator promptly after all drilling and completion operations that caused such Drilling Unit to be an Excluded Unit have been concluded by CONSOL Operator. Unless otherwise mutually agreed, the right to expand the NBL Operated Area shall automatically terminate at the time that all counties listed on Schedule 2.3(c) have become part of the NBL Operated Area (excluding any Excluded Units).

(d)    Notwithstanding anything in the Agreement to the contrary, beginning on the Closing Date and ending on the date that is 90 days following the date on which CONSOL Operator receives written notice from Noble Operator that it is electing to assume operatorship of the NBL Operated Area, or such earlier date as CONSOL Operator and Noble Operator may mutually agree (the “Operatorship Transition Period”), the NBL Operated Area shall be deemed to be a part of the CNX Operated Area and CONSOL Operator shall serve as Party Operator of such Operated Area; provided that in the event that Noble Operator does not provide such notice to CONSOL Operator on or before December 31, 2012, then the Operatorship Transition Period shall terminate, the NBL Operated Area thereafter shall be deemed to cover none of the Development Area, the CONSOL Operated Area shall be deemed to cover both the area initially defined as the NBL Operated Area and the area initially defined as the CONSOL Operated Area and the provisions of Section 2.3(c) shall no longer be applicable. During the Operatorship Transition Period, prior to commencing any Development Operation in the Operated Area that is described on Exhibit A-3, CONSOL Operator shall provide a copy of any AFE and any related drilling and completion plan for such Development Operation to Noble Operator and thereafter meet with Noble Operator to discuss and review such AFE and/or related drilling and completion plan. At the end of the Operatorship Transition Period, CONSOL Operator shall use its commercially reasonable efforts to assist Noble Operator in taking over as operator in the NBL Operated Area.

2.4    Operating Agreements.

  

(a)    Except for any Unit JOAs that are executed and delivered by the Parties on the Closing Date, all Leases and related assets in the Development Area: (i) in which only the Parties hold interests as of the Closing Date, or (ii) in which the Parties hereafter both acquire interests, shall be deemed to be subject to and governed by an operating agreement in the form attached hereto as Exhibit B-1 (the “Master JOA”); provided that with respect to those Subject Assets that are subject to any Third Party Operating Agreement,

only the lien provisions of the Master JOA shall be applicable to such Subject Assets. On the Closing Date, the Master JOA shall be executed by the Parties and shall cover all such Subject Assets (including those Subject Assets that are subject to a Third Party Operating Agreement), excluding, however, those Subject Assets that are covered by a Unit JOA. All Leases and related assets in the Development Area in which the Parties hereafter both acquire interests that are not subject to a Third Party Operating Agreement, shall automatically become subject to the Master JOA and, within 30 days following the end of each calendar quarter, the Parties shall supplement and/or amend each applicable Master JOA Agreement to reflect the addition of such Leases and related assets; provided that to the extent that such Leases and related assets are Developed Assets and not subject to a Third Party Operating Agreement at the time of acquisition, then such Leases and related assets shall become subject to a Unit JOA to be executed by the Parties at the time of the acquisition of such Leases and related assets. For those Subject Assets that are subject to a Third Party Operating Agreement, such Third Party Operating Agreement shall govern the operations thereon; provided that if such Subject Assets as of the Closing Date are not Developed Assets, then the lien provisions of the Master JOA shall be applicable to such Subject Assets.

(b)    On the Closing Date, the Parties shall execute and file a separate Memorandum of Operating Agreement, Lien and Financing Statement, in the case of Noble, in the form attached hereto as Exhibit B-2 (the “Noble Master JOA Memorandum”), and, in the case of CONSOL, in the form attached hereto as Exhibit B-3 (the "CONSOL Master JOA Memorandum" and, together with the Noble Master JOA Memorandum, the "Master JOA Memoranda") and related financing statements for the Master JOA and, within 30 days of the Closing Date, the Parties will file such Master JOA Memoranda in the real property records of each county in which the Subject Assets that are covered by the Master JOA are located and such financing statements in the proper office under the Uniform Commercial Code in the states in which such Subject Assets are located.

(c)    From and after the Closing Date, if a Drilling Unit is designated by CONSOL Operator or Noble Operator to cover a specified portion of the Subject Assets covered by the Master JOA that is not also covered by a Third Party Operating Agreement and such portion of the Subject Assets covered by such Drilling Unit become Developed Assets, then the Master JOA shall automatically be deemed to not cover such portion of the Subject Assets and a separate operating agreement in the form attached hereto as Exhibit D-1 (each, a “Unit JOA”), with CONSOL Operator or Noble Operator serving as operator (as applicable pursuant to Section 2.3) shall be deemed to cover such portion of the Subject Assets with respect to such Drilling Unit. Further, from and after the Closing Date, if any portion of the Subject Assets that are subject to a Third Party Operating Agreement become Developed Assets, then the Master JOA shall automatically be deemed to not cover such portion of the Subject Assets and only such Third Party Operating Agreement shall cover such portion of the Subject Assets.

(d)    Within 30 days following the end of each calendar quarter, the Parties shall (i) modify or amend the Master JOA and each Master JOA Memoranda and related financing statements (including making any filings necessary to reflect such modifications or amendments in the applicable real property and other public records) to reflect any Subject Assets that have become subject to, or removed from, the Master JOA during the previous calendar quarter, (ii) execute and deliver separate Unit JOAs to cover any Subject Assets that have been deemed to have become subject to a Unit JOA during the previous calendar quarter and (iii) execute and file a separate Memorandum of Operating Agreement, Lien and Financing Statement, in the case of Noble, in the form attached hereto in Exhibit D-2 (the “Noble Unit JOA Memorandum”), and, in the case of CONSOL, in the form attached hereto as Exhibit D-3 (the “CONSOL Unit JOA Memorandum” and, together with the Noble Unit JOA Memorandum, the “Unit JOA Memoranda”) and related financing statements for each Unit JOA that is being executed and delivered pursuant to clause (ii) above and file such Unit JOA Memoranda in the real property records of each county in which the Subject Assets that are covered

by the applicable Unit JOA are located and in the proper office under the Uniform Commercial Code in the states in which such Subject Assets are located.

(e)    In addition, subject to Section 2.4(a), the Parties agree to use their respective commercially reasonable efforts to have the form of the Unit JOA adopted as the operative operating agreement by all Working Interest owners for any Drilling Unit in the Development Area in which Persons other than the Parties hold Working Interests.

(f)    As between the Parties, each Applicable Operating Agreement shall be subject to the provisions of the Tax Partnership Agreement unless and until the applicability of such provisions to the Subject Assets subject to each such Applicable Operating Agreement terminates in accordance with the terms of the Tax Partnership Agreement.

2.8    Insurance.

  

(a)    Each Party Operator shall use its commercially reasonable efforts to carry insurance for the benefit of the joint account of the Parties as outlined in Exhibit C (or at such other insurance level as the Joint Development Committee may approve) for those Subject Assets for which it serves as operator. Each Party Operator shall provide copies of such policies to the Parties covered by such policies upon request, and shall notify all Parties to be covered by such policies if it has been unable to obtain or maintain any of such policies. Except for worker's compensation policies, each Party Operator shall use its commercially

reasonable efforts to arrange for each of the Parties, according to their respective interests, to be named as additional insureds on the relevant policies, with waivers of subrogation in favor of all Parties with respect to their interests under this Agreement or such Applicable Operating Agreement where such Party Operator is the operator, as applicable. Each Party Operator shall use commercially reasonable efforts to duly file any relevant claims and to collect for the account of the relevant Parties any proceeds under such policies.

(b)    Notwithstanding the foregoing, any Party may obtain such insurance as it deems advisable for its own account at its own expense. Such insurance shall, in so far as it relates to Development Operations or Area-Wide Operations, contain a waiver of subrogation by the insurers in favor of each of the other Parties. Each Party Operator shall reasonably cooperate and assist such insurers in the investigation of insurance claims made by a Party in connection with the operations performed hereunder.

(a)    Production. Each Party retains and reserves the right to take-in-kind all of its Production in the CNX Operated Area and the Noble Operated Area subject to the terms of this Section 2.10.

(b)    Gas Production.

(i)    For the Interim Marketing Period, Noble hereby designates CONSOL Operator as marketer of Noble's Gas Production (“Marketer”), in the CNX Operated Area and in the Noble Operated Area, produced during the Interim Marketing Period in accordance with and subject to the following terms of this Section 2.10. During the Interim Marketing Period and subject to the remaining provisions of this Section 2.10, Marketer shall have authority and responsibility to market and sell such Gas Production (but not hedge such Gas Production) and to enter into sales, transportation, gathering and treatment agreements with respect to such Gas Production on behalf of the Party that owns the same (a “Marketing Transaction”); provided that Marketer shall not enter into a Marketing Transaction that (i) has a noncompetition provision, area of mutual interest restriction, preferential purchase right, or dedication of properties or (ii) a term that extends beyond March 31, 2013, in each case, that is binding upon a Party without the prior written consent of such Party. For each Marketing Transaction, Noble's Gas Production in an Operated Area shall be marketed on terms at least as favorable as terms received by Marketer for its share of Gas Production during the Interim Marketing Period and Marketer will market all Gas Production on market-based terms as reasonably determined in good faith by Marketer. Unless Noble otherwise consents to the same in writing, none of Noble's Gas Production may be marketed to Marketer itself or any Affiliate of Marketer. During the Interim Marketing Period, title to Noble's Gas Production will pass to (A) with respect to all processed natural gas liquids, condensate or other processed products from such Gas Production (“Processed Gas Production”),

to the processor at the point at which title is required to be transferred to such processor under the applicable processing agreement and (B) with respect to all other such Gas Production (“Residual Gas Production”), to Marketer at the first delivery point location into an interstate natural gas pipeline system. During the Interim Marketing Period, all Residual Gas Production shall be sold under the NAESB Agreement and the related transaction confirmations. Furthermore, during the Interim Marketing Period, title to Noble's Gas Production shall at all times remain with Noble until such time as title is passed to another Person as described above, such that all products, both volume and value, sold on behalf of Noble or directly by Noble is to be reported as production volume, sales and revenue, by Noble. During the Interim Marketing Period, the Parties will cause their Gas Production to be delivered pursuant to the Processing Agreements, as required.

(ii)    During the Interim Marketing Period, Marketer will make all nominations that are required under the terms of any of its Marketing Transactions. As requested by Marketer from time to time, Noble will reasonably cooperate and coordinate with Marketer in order to permit Marketer to perform under the terms of each of its Marketing Transaction with respect to Noble's Gas Production and Noble shall indemnify, defend and hold Marketer harmless from any breach of any Marketing Transaction to the extent arising from Noble's failure to so reasonably cooperate and coordinate.

(iii)    Subject to Section 8.3(a), during the Interim Marketing Period Marketer shall remit to Noble all amounts due to Noble under the NAESB Agreement as and when due under the NAESB Agreement.

(iv)    At the end of the Interim Marketing Period, each Party will take-in-kind any and all of its Gas Production in the CNX Operated Area and the Noble Operated Area and provide its own full marketing services.

(c)    Transportation and Processing.

(i)    After the Interim Marketing Period, subject to Section 2.10(c), each Party shall be responsible for obtaining their own gathering, processing and transportation agreements with respect to their Gas Production. Prior to the end of the Interim Marketing Period and, if and to the extent required by Schedule 2.10(a), thereafter, each Party will comply with the terms of Schedule 2.10(a) with respect to the Downstream Contracts and the Peoples Contract.

(ii)    During the Interim Marketing Period and for so long thereafter as CONSOL holds any of the Downstream Contracts for the benefit of Noble pursuant to Schedule 2.10(a), Noble shall be responsible for, and shall pay in accordance with Section 7.2, all demand charges and tariffs required to be paid by CONSOL with respect to such Downstream Contracts to the extent applicable to the Assigned FT Interests. During the Interim Marketing Period, Noble shall be responsible for, and shall pay in accordance with Section 7.2, in addition to any other amounts set forth herein, in the NAESB Agreement or any related transaction confirmations, a daily reservation fee of $2,700. During the Interim Marketing Period, with respect to that amount of Noble's and its Affiliates' Gas Production that is delivered to the Texas Eastern Transmission interstate pipeline in Marshall, West Virginia, Green, Pennsylvania, Fayette, Pennsylvania, Westmoreland, Pennsylvania, or Indiana, Pennsylvania, that is in excess of 54,000 MMBtu per day but less than 104,001 MMBtu per day (the “Excess Gas Production”), CONSOL shall purchase such Excess Gas Production under the terms of the NAESB Agreement and the related transaction confirmations at the inlet meter of the Texas Eastern Transmission interstate pipeline and, notwithstanding anything in this Section 2.10, the NAESB Agreement or any related transaction confirmation to the contrary, pay Noble and its Affiliates in respect of such Excess Gas Production as and when required under the terms of the NAESB Agreement an amount equal to (x) the first of the month Platts Inside F.E.R.C's Gas Market Report, “Price of Spot Gas

Delivered to Pipelines,” for deliveries at Appalachian Lebanon Hub for the calendar month in which such Excess Gas Production is so delivered multiplied by (y) the amount of Excess Gas Production delivered during such calendar month.

(iii)    For purposes of flow assurance for each Party's share of Gas Production, it is the intent of the Parties to participate equally in any future processing agreements for Gas Production obtained by either Party after the Closing Date. If either Party desires to acquire additional processing capacity, then prior to entering into negotiations for a new processing agreement, such Party shall provide written notice to the Joint Development Committee, which shall include, the general deal parameters and the portion or portions of the Subject Assets within the Development Area that would be affected by such new processing agreement (a “Proposed Processing Agreement”). At the next meeting of the Joint Development Committee following such submission, the Joint Development Committee shall vote to authorize or not authorize a Party (the “Negotiating Party”) to negotiate the Proposed Processing Agreement on behalf of the Parties. Any members of the Joint Development Committee appointed by the Party (or its Affiliates) that submits a proposal for a Proposed Processing Agreement shall be deemed to have voted to authorize a Negotiating Party to negotiate the terms of a Proposed Processing Agreement on behalf of the Parties in accordance with this Section 2.10(b)(iii). If the Joint Development Committee fails to authorize a Negotiating Party to negotiate a Proposed Processing Agreement on behalf of the Parties, then the Party making the proposal to acquire additional processing capacity may enter into a processing agreement covering the subject matter of the proposal for the Proposed Processing Agreement (with such revisions as are necessary to account for only such Party's Gas Production being subject to such agreement). If the Joint Development Committee authorizes a Negotiating Party to negotiate the Proposed Processing Agreement on behalf of the Parties, then, for a period of 90 days following the date of such authorization, such Negotiating Party shall have the exclusive right to negotiate such Proposed Processing Agreement on behalf of the Parties and no other Party shall negotiate or enter into any processing agreement relating to the subject matter of such Proposed Processing Agreement; provided that if such Negotiating Party fails to negotiate such Proposed Processing Agreement within such 90-day period, then such Negotiating Party will no longer have the right to negotiate such Proposed Processing Agreement (and until it resubmits a written notice to the Joint Development Committee to obtain the Joint Development Committee's authorization of another Proposed Processing Agreement in accordance with the provisions of this Section 2.10(b)(iii)). In negotiating any Proposed Processing Agreement, the Negotiating Party shall use its commercially reasonable efforts to negotiate any processing agreement or agreements on market based terms and to negotiate separate processing agreements for each Party (with the same terms and other than revisions necessary to account for each Party's separate Gas Production). Upon completion of such negotiations, if applicable, the Negotiating Party shall submit the final Proposed Processing Agreement or agreements to the Joint Development Committee. At the next meeting of the Joint Development Committee following such submission, the Joint Development Committee shall vote to approve or disapprove such agreement or agreements. If the Joint Development Committee approves such agreement or agreements, then each Party shall promptly execute and deliver such agreement or, if applicable, its respective agreement. If the Joint Development Committee fails to approve a Proposed Processing Agreement or Proposed Processing Agreements after such agreement(s) has been negotiated by the Negotiating Party, then the Party whose members of the Joint Development Committee voted to approve such final Proposed Processing Agreements or agreements may enter into a processing agreement covering the subject matter of the Proposed Processing Agreement (with such revisions as are necessary to account for only such Negotiating Party's Gas Production being subject to such agreement).

(iv)    Upon mutual agreement of the Parties, the Parties shall have the right, prior to September 25, 2011, to unwind the production dedication under the Processing Agreements in accordance with the terms of the Processing Agreements.

(d)    Hedging. Each Party will be responsible for conducting (for its own account) any hedging activities with respect to its Production from the Subject Assets.

(e)    Administrative Services and Reporting. Each Party or Party Operator conducting marketing activities under this Section 2.10 on behalf of another Party shall also be responsible for providing any accounts receivable, collection, revenue accounting, system balancing and other back office marketing services necessary to market such Production. Each Party or Party Operator conducting marketing activities under this Section 2.10 on behalf of another Party shall provide to such other Party the following reports and information as such data and reports are produced or compiled (unless otherwise provided below) relating to the Production being marketed hereunder on behalf of such other Party:

(i)    counterparty credit exposure reports, as amended from time to time, which reports shall include a list of counterparties with to which the Parties have credit exposure, the maximum amount of potential credit exposure to each such counterparty for a 60-day period (regardless of any outstanding credit extensions to such counterparty at the time of such report) and any outstanding credit extensions to such counterparty at the time of such report;

(ii)    prior to the first day of each calendar month, a listing on anticipated sales and volumes by counterparty for the production of such Party being sold during such relevant calendar month;

(iii)    copies of all transaction confirmations entered into under any NAESB agreement or similar agreement to which such Party or Party Operator is a party; and

(iv)    any other data or information that a Party whose production is being marketed hereunder may reasonably request relating to its Production.

(f)    Wellhead Condensate Production. From and after the Closing Date, each Party Operator shall have exclusive authority and responsibility to market and sell all of the Wellhead Condensate Production of the Parties in the Operated Area in which it operates (but not hedge such Wellhead Condensate Production), and to enter into any necessary marketing agreements for such Wellhead Condensate Production. A Party Operator shall not enter into any marketing agreement that has a noncompetition provision, area of mutual interest restriction, preferential purchase right or dedication of properties that is binding upon a Party without the prior written consent of such Party. Each Party's Wellhead Condensate Production in an Operated Area shall be marketed by the applicable Party Operator on market-based terms at least as favorable as terms received by the applicable Party Operator for its share of Wellhead Condensate Production and the applicable Party Operator will market all Wellhead Condensate Production on market-based terms as reasonably determined in good faith by the applicable Party Operator. Unless a Party otherwise consents to the same in writing, none of such Party's Wellhead Condensate Production may be marketed to the Party Operator marketing such Wellhead Condensate Production or any Affiliate of such Party Operator. Title to a Party's Wellhead Condensate Production will remain in such Party until such time as title to such Wellhead Condensate Production is required to be transferred to the purchasing counterparty under the terms of the applicable sales contract. As requested by a Party Operator from time to time, each Party will reasonably cooperate and coordinate with such Party Operator in order to permit such Party Operator to market such Party's Wellhead Condensate Production. All net proceeds from a Party's Wellhead Condensate Production received by a Party Operator shall be held for the account of such Party and delivered by such Party Operator no later than the 25th day of the calendar month following receipt thereof by such Party Operator to an account designated by the applicable Party.

(g)    Drip Condensate Production. From and after the Closing Date, each Party's Drip Condensate

Production will be handled by the gatherer of any applicable gathering agreement. Title to a Party's Drip Condensate Production will remain in such Party until such time as title to such Drip Condensate Production is required to be transferred to the gatherer under the terms of the applicable gathering agreement.

(d)    Periodic Review. On or before August 31 in the calendar year immediately preceding the relevant calendar year, the Joint Development Committee shall review the calculation of Services Costs being charged by each Party Operator pursuant to the then current Annual Plan and Budget and the amount of the Marketing Fees chargeable by CONSOL and vote to approve the calculation of such Services Costs and the amount of such Marketing Fee for the following year (each of which may be modified by the Joint Development Committee). If the Joint Development Committee fails to approve the calculation of such Services Costs or the amount of such Marketing Fee (with any modifications that the Joint Development Committee may approve) for such following year, then any Party may submit such matter to an expert in accordance with Section 11.7(b) and such expert shall adjust such calculation and/or fees so that the amount of Services Costs and/or Marketing Fees chargeable to the Parties under this Section 2.11 equals in such expert's opinion a market rate for fees being charged for similar services by other Persons in the Development Area at the time of such adjustment.

2.12    Contracts; Use of Affiliates.

All services performed and materials supplied by any such Affiliates or related parties shall be performed or supplied at arm's length and on competitive rates, pursuant to written agreements, and in accordance with customs and standards prevailing in the industry.

(c)    Notwithstanding Sections 2.12(a) or 2.12(b) or any Applicable Operating Agreement to the contrary, unless either (i) such contract has been approved by the Joint Development Committee or (ii) such contract is expressly contemplated by an Annual Plan and Budget, a Party Operator shall not enter into an Affiliate Contract or a contract or agreement that contains a confidentiality obligation that would prevent such Party Operator from providing to the other Parties the data and reports required by Section 2.9(a).

2.13    Non-Solicitation.

  

(a)    During the term of this Agreement and for a period of 12 calendar months thereafter, Noble and its Affiliates may not solicit or hire any officer or employee of CONSOL or its Affiliates without first obtaining the prior written consent of CONSOL; provided that this prohibition shall not apply to offers of employment made by Noble or its Affiliates pursuant to a general solicitation of employment to the public or the industry.

Section 3.1(h) and to provide (directly or through a subcommittee) advice and recommendations for the conduct of Development Operations and Area-Wide Operations, there is hereby established a joint development committee composed of representatives of CONSOL and Noble (the “Joint Development Committee”). CONSOL shall be entitled to appoint three representatives to the Joint Development Committee and Noble shall be entitled to appoint three representatives to the Joint Development Committee. The initial representatives to the Joint Development Committee for CONSOL shall be Randall M. Albert, M. Charles Hardoby and Stephen W.

On all matters coming before the Joint Development Committee, the representatives of each of CONSOL and Noble shall have an aggregate vote equal to the Participating Interest of the Person (and its Affiliates) that appointed such representatives divided by the aggregate Participating Interests of all Persons (and their Affiliates) with representatives on the Joint Development Committee. Any representative of a Party that is present or otherwise available to vote or consent on an action of the Joint Development Committee shall have the authority to cast all of the votes or consents allocated to all of the representatives of such Party. In addition to the representatives, each Party may also send such advisors as it may deem appropriate to any Joint Development Committee meetings.

(d)    Unless otherwise agreed to by the members of the Joint Development Committee, the Joint Development Committee shall meet once (and no more than once unless otherwise mutually agreed) per calendar month to review and discuss reports concerning the Development Plan, Annual Plan and Budget and the drilling schedule, relevant geoscience and other data relating to Subject Assets and such other matters as may be reasonably proposed by a Party Operator or members of the Joint Development Committee. Meetings of the Joint Development Committee may be called by either CONSOL Operator or NBL Operator by giving notice to the members of the Joint Development Committee at least 5 days in advance of such meeting, along with a proposed agenda for such meeting (which shall include any items that a member of the Joint Development Committee or a Party Operator may request to have included on such agenda). All meetings shall be held during normal business hours at a time and place agreed to by CONSOL Operator and NBL Operator, or failing to reach such agreement, meetings occurring in even numbered months shall be held in a location selected by NBL Operator and meetings held in odd numbered months shall be held in a location selected by CONSOL Operator; provided that members of the Joint Development Committee shall be allowed to participate telephonically (or, to the extent available, by video conference) in any such meeting.

(e)    All decisions, approvals and other actions of the Joint Development Committee shall be decided by the affirmative vote of members of the Joint Development Committee holding collectively at least two-thirds of the votes eligible to vote on such proposals (which eligible votes, for the avoidance of doubt, shall not include any votes by the representatives of any Defaulting Party in accordance with Section 8.2(a)).

Each Party

agrees and acknowledges that each member of the Joint Development Committee shall be entitled to determine whether or not to take any action under this Agreement or any Associated Agreement by only considering the interests of the Party that designated such member to the Joint Development Committee and not the interests of the other Party.

(f)    In lieu of a meeting, any Party Operator may submit any proposal that is within the Joint Development Committee's powers to approve or disapprove (including any amendment to the then existing Development Plan or Annual Plan and Budget) to the Joint Development Committee for a vote by written notice. Such Party Operator shall provide a copy of any such proposal by written notice to the members of the Joint Development Committee. The members of the Joint Development Committee shall communicate their votes on the proposal by written notice to the submitting Party Operator within 14 days after receipt of the proposal from such Party Operator.

(g)    The Joint Development Committee may establish such subcommittees as it may deem appropriate, including a technical committee (whose purpose would be to advise the Party Operators with respect to the development of the Subject Assets, the coordination of Development Services, the selection of Third Party contractors, the terms of contracts for Development Operations and such other matters as the Joint Development Committee may direct). The functions of such subcommittees shall be to serve in an advisory capacity only. CONSOL and Noble shall each have the right to appoint an equal number of representatives to each subcommittee. The Joint Development Committee is hereby deemed to have established a HSE Committee (the “HSE Committee”) whose purpose shall be to (A) review violations of applicable health, safety and environmental Law by a Party Operator and (B) collaborate with each Party Operator to develop additional health, safety and environmental policies and programs in its Operated Area.

Development Committee an amendment to the portion of the then existing Development Plan covering such Operated Area, which amendment sets forth the Development Operations and Area-Wide Operations reasonably expected to be carried out during the following three calendar years in such Operated Area. Following distribution of all amendments to the Development Plan from each of the Party Operators, the representatives of the Joint Development Committee shall have 30 days to furnish to the other members of the Joint Development Committee any proposed revisions they desire to make to the proposed amendments to the Development Plan. Promptly following the Joint Development Committee's 30-day review process, the Joint Development Committee shall meet to consider the amendments to the Development Plan and any recommendations made with respect thereto by any member of the Joint Development Committee and approve or reject such amendments to the Development Plan and such recommendations. In addition, the Joint Development Committee shall annually review the Development Plan in connection with its annual review and approval of the Annual Plan and Budget for the following calendar year and may from time to time amend or modify the Development Plan.

(d)    For the avoidance of doubt, any reference in this Agreement to the Development Plan shall mean the Development Plan attached hereto as Exhibit E, as such Development Plan may be amended from time to time by the Joint Development Committee pursuant to the terms hereof.

3.3    Annual Plan and Budgets.

  

(a)Attached hereto as Exhibit F is an annual development plan and budget for Development Operations and Area-Wide Operations which the Parties currently anticipate to be conducted by the Party Operators through calendar year 2012 (as hereafter amended, modified or supplemented, the “Annual Plan and Budget”). Each Party Operator shall, with respect to its Operated Area, be responsible for conducting the Development Operations and Area-Wide Operations that are contemplated by, and in accordance with, the then applicable Annual Plan and Budget covering such Operated Area. The Joint Development Committee shall have the sole right to amend, modify and supplement any Annual Plan and Budget.

(b)Other than with respect to calendar year 2011, on or before August 31 in the calendar year immediately preceding the relevant calendar year, each Party Operator shall, with respect to its Operated Area, prepare and submit to the Joint Development Committee that portion of a proposed Annual Plan and Budget for such relevant calendar year that pertains to such Operated Area. In preparing such portion of such proposed Annual Plan and Budget, each Party Operator shall prepare such Annual Plan and Budget in a manner consistent with the then current Development Plan for such relevant calendar year. Each such portion of such proposed Annual Plan and Budget submitted by a Party Operator shall contain at least the following with respect to the Operated Area of such Party Operator:

(i)all Development Operations and Area-Wide Operations that are expected to be conducted by such Party Operator in its Operated Area during such calendar year;

(ii)all lease maintenance costs and expenditures required under the terms of existing Leases or existing Third Party contracts held by a Party Operator for the benefit of Development Operations and Area-Wide Operations (including each Party's share thereof);

(iii)itemized estimates of the Development Costs (including each Party's share thereof including Carried Costs, separately stated, in the case of Noble) for Development Operations and Area-Wide Operations covered by the proposed Annual Plan and Budget by budget category containing sufficient detail, if available, to afford the ready identification of the nature, scope and duration of the activity in question;

(iv)the number of wells proposed to be drilled as part of the Development Operations and Area-Wide Operations during such calendar year, the areas for drilling groups of wells and proposed locations of such wells (to the extent reasonably ascertainable at the time such Annual Plan and Budget is proposed), and the estimated Development Costs (including each Party's share thereof) associated therewith;

Each Party Operator shall also provide to the Joint Development Committee any technical and interpretive data to support its proposed portion of the Annual Plan and Budget that any member of the Joint Development Committee may reasonably request.

(c)Following distribution of the applicable portion of the proposed Annual Plan and Budget from each of the Party Operators, the representatives of the Joint Development Committee shall have 30 days to furnish to the other members of the Joint Development Committee any proposed revisions they desire to make to such proposed Annual Plan and Budget. Promptly following the Joint Development Committee's 30-day review process, the Joint Development Committee shall meet to consider the proposed Annual Plan and Budget and any recommendations made with respect thereto by any member of the Joint Development Committee and approve or reject the proposed Annual Plan and Budget and such recommendations. In addition to annually submitting an Annual Plan and Budget to the Joint Development Committee, commencing in 2012, on or prior to June 30 of each calendar year, each Party Operator shall meet with the Joint Development Committee to review the then current Annual Plan and Budget to discuss any potential amendments or modifications to such Annual Plan and Budget for the remaining portion of such calendar year that may be proposed by the members of the Joint Development Committee or such Party Operator.

(d)Inclusion of an operation in an approved Annual Plan and Budget shall (unless and until such operation is removed from such Annual Plan and Budget pursuant to an amendment thereof): (i) bind all Parties to participate in such operation, and no Party shall have the right to make any nonconsent election under an Applicable Operating Agreement with respect to such operation; and (ii) subject to an occurrence of a Force Majeure Event affecting such operation, authorize the applicable Party Operator to propose and conduct such operation for the account of all of the Parties under the relevant Applicable Operating Agreement (provided that, to the extent any Third Party is a party to such Applicable Operating Agreement, a Party Operator shall propose such operation to such Third Party in accordance with the terms of such Applicable Operating Agreement, though, for the avoidance of doubt, such Party Operator need not re-propose such operation to the Parties but the Party Operator shall provide any AFEs required by the terms of the Applicable Operating Agreement to such Party, which shall be for informational purposes only) or under this Agreement in the case of an Area-Wide Operation.

(e)Subject to a Force Majeure Event that affects such Development Operations, each Party Operator shall be responsible for proposing, and shall conduct, Development Operations relating to its Operated Area that are contemplated in an Annual Plan and Budget under the Applicable Operating Agreement; provided that, notwithstanding anything to the contrary in this Agreement, no Party Operator shall have any liability for failing to commence operations to drill all of the wells set forth in the applicable

Annual Plan and Budget for any year for its Operated Area so long as such Party Operator proposes and commences the drilling of at least 95% of the wells contemplated to be drilled in an Annual Plan and Budget for its Operated Area for such year. Other than as provided in the preceding sentence or as provided in Section 3.3(g), no Party or its Affiliates (including any Party Operator) shall propose Development Operations under any Applicable Operating Agreement. Other than with respect to Development Operations proposed by a Third Party Operator or a Third Party under an Applicable Operating Agreement, each Party hereby authorizes each Party Operator on its behalf to provide such notices, make such elections and take such actions as may reasonably be required under any Applicable Operating Agreement or any other Associated Agreement to implement the operations and activities contemplated by an approved Annual Plan and Budget in such Party Operator's Operated Area. In the event that an operation that is included in an approved Annual Plan and Budget is proposed by a Party Operator under an Applicable Operating Agreement and a Third Party to such Applicable Operating Agreement non-consents such proposal, then (i) if the Working Interest of the non-consenting Third Party with respect to such proposed operation is less than 50%, each Party shall be required to participate for its full Working Interest share of the Working Interest of such non-consenting Third Party and the applicable Party Operator shall make such elections, on behalf of each Party, as is necessary to implement the same and (ii) if the Working Interest of the non-consenting Third Party with respect to such proposed operation is 50% or more, each Party shall have the right to elect to participate for its full Working Interest share of the Working Interest of such non-consenting Third Party in accordance with the terms of the Applicable Operating Agreement; provided that if any Party elects not to participate for its full Working Interest share of the Working Interest of such non-consenting Third Party, the Party Operator shall have the option to withdraw its proposal for such Development Operation (and if the Party Operator withdraws such proposal, such Development Operation shall be deemed to have been removed from the Annual Plan and Budget).

(f)Each Party shall have the right to elect to participate or not to participate in any Development Operations proposed by a Third Party Operator or other Third Party pursuant to an Applicable Operating Agreement. Any such Development Operation in which less than all of such Parties elect to participate as permitted hereunder may be conducted by the Parties electing to participate in such Development Operation under the terms of the relevant Applicable Operating Agreement. Except as provided in Section 3.5 with respect to a Non-Consent Year, Noble's obligation to pay the Carried Costs on behalf of CONSOL in accordance with Section 7.1 shall not apply to Development Operations proposed by a Third Party Operator or other Third Parties pursuant to an Applicable Operating Agreement unless Noble is a participating party in such Development Operation.

(g)In the event that the Joint Development Committee fails to approve an Annual Plan and Budget for a particular calendar year on or prior to December 15 of the year preceding such particular calendar year (for purposes of this Section 3.3(g), such particular year for which the Joint Development Committee fails to approve an Annual Plan and Budget, the “relevant calendar year”), the Joint Development Committee shall be deemed to have approved an Annual Plan and Budget for such relevant calendar year that includes the following: (i) all Development Operations and Area-Wide Operations that were previously commenced pursuant to an approved Annual Plan and Budget in a prior calendar year and not completed in such prior calendar year; (ii) the wells scheduled to be drilled during the relevant calendar year as set forth in the Development Plan, if any, and the associated Development Costs reasonably expected to be required to implement such Development Operations (regardless of estimated amounts set forth in the Development Plan); (iii) all actual Operating Expenses relating to the subject assets and incurred during the relevant calendar year; (iv) Services Costs and overhead rates and Marketing Fees (and related Third Party expenses) in accordance with Section 2.11 (provided that if the Services Costs or Marketing Fee (as applicable) are not then approved by the Joint Development Committee or determined by an expert pursuant to Section 2.11(d), then until so approved or determined, such cost or fee shall be equal to the Services Costs or Marketing Fee

(as applicable) for the preceding calendar year); (v) existing payment commitments to Third Parties under Leases and binding contracts with respect to the Subject Assets; and (vi) taxes payable with respect to the Subject Assets by a Party Operator under the terms of any Applicable Operating Agreement. In the event that any Development Operation scheduled to be performed during any calendar year is not commenced during such calendar year, then the Development Plan shall automatically be amended to add such Development Operation to the Development Plan to be conducted in the year following the year in which the Development Plan would have otherwise expired and the Development Plan shall be automatically extended for such period of time as is reasonably necessary for the applicable Party Operator to conduct such Development Operation.

(h)Subject to Section 7.1 and subject to the applicable Annual Plan and Budget (as modified by Section 3.3(i)), each Party shall be responsible for such Party's Share of Development Costs, including its Share of Development Costs for operations conducted by a Party Operator in accordance with Section 3.3(j). Subject to Section 7.1, each Party shall pay or advance its Share of Development Costs in accordance with Section 7.2. For the avoidance of doubt, no Party shall be obligated to participate in acquisitions of Leases included in an Annual Plan and Budget (other than Fill-In Interests), if any, but instead shall have the right but not the obligation to participate in such acquisitions pursuant to ARTICLE V.

(i)Approval by the Joint Development Committee of an Annual Plan and Budget shall constitute the Joint Development Committee's deemed approval for any Party Operator to expend up to 20% in excess of the authorized amount applicable to its operations in its Operated Area within each Annual Plan and Budget category, not to exceed in the aggregate 10% of the aggregate amount applicable to such operations in such Annual Plan and Budget. Each Party Operator shall promptly notify the Joint Development Committee of any expenditure made by it in the exercise of its rights pursuant to this Section 3.3(i). The deemed approval levels set forth in this Section 3.3(i) shall be calculated with respect to the original amount of an Annual Plan and Budget or, once amended, the amended amount of the Annual Plan and Budget, provided that no expenditures incurred pursuant to Section 3.3(j) shall be deemed to be included in an approved Annual Plan and Budget for purposes of calculating the deemed approval levels pursuant to this Section 3.3(i), nor shall any such expenditures be considered to be amounts expended in excess of the authorized amount of any Annual Plan and Budget for purposes of calculating the deemed approval levels set forth in this Section 3.3(i).

(j)Notwithstanding anything to the contrary in this Agreement, each Party Operator is expressly authorized to make expenditures and incur liabilities when it reasonably determines that such expenditures or incurrences are necessary or advisable to deal with emergencies, including well blowouts, fires, oil spills, or any other similar event, which may endanger property, lives, or the environment. Each Party Operator shall as soon as practicable report to the Parties the nature of any such emergency which arises, the measures it intends to take or has taken in respect of such emergency and the estimated related expenditures.

(k)To the extent reasonably within the control of any Party Operator conducting any Development Operation and subject to any Force Majeure Event affecting such Development Operation, each Development Operation shall be conducted at approximately the time prescribed in the applicable Annual Plan and Budget.

(l)For the avoidance of doubt, any reference in this Agreement to an Annual Plan and Budget in connection with any operations, rights or obligations shall mean an Annual Plan and Budget that is approved or deemed to have been approved by the Joint Development Committee, including all amendments to such Annual Plan and Budgets that are approved (or deemed approved) by the Joint Development Committee pursuant to the terms hereof.

3.4    AFEs. Prior to any Party Operator (a) spudding any well included in the Annual Plan and Budget, or (b) making any expenditure that is included in the Annual Plan and Budget and that is estimated to cost in excess of $500,000, such Party Operator shall submit an AFE to the Parties covering such well or expenditure for information purposes only.

3.5    Non-Consent Years. Notwithstanding any other provision in this Agreement to the contrary, subject and pursuant to the terms and provisions of this Section 3.5, each of Noble and CONSOL shall have the right (the “Non-Consent Right”) to elect to non-consent all (but not less than all) wells to be drilled in the Development Area under the Annual Plan and Budget deemed approved pursuant to Section 3.3(g) during a Non-Consent Year in the event that the Joint Development Committee fails to approve an Annual Plan and Budget for such Non-Consent Year.

(a)    Non-Consent Right.

(i)Commencing in calendar year 2013, on or prior to December 20 of any calendar year, either Noble or CONSOL may exercise its Non-Consent Right with respect to the following calendar year (such following calendar year, the “Non-Consent Year”) by giving written notice of the same to all other Parties. For clarity, no calendar year prior to 2014 can be a Non-Consent Year. For clarity, a Party electing to exercise the Non-Consent Right shall be entitled to elect to participate in any wells that are not included in the Annual Plan and Budget for the Non-Consent Year (being the Annual Plan and Budget deemed approved pursuant to Section 3.3(g)) proposed to be drilled by a Third Party Operator or Third Party under any Applicable Operating Agreement in the Non-Consent Year on a well-by-well basis.

(ii)If either Noble or CONSOL (the “Non-Consenting Party”) exercises its Non-Consent Right for a Non-Consent Year, then (A) such Non-Consenting Party shall not be entitled or obligated to conduct, propose or otherwise participate in any wells included in the Annual Plan and Budget for the Non-Consent Year (being the Annual Plan and Budget deemed approved pursuant to Section 3.3(g)) for which drilling operations are commenced in the Development Area during the Non-Consent Year and (B) the other Party (the “Electing Party”) shall have the right (but not the obligation, notwithstanding anything herein to the contrary) to propose and drill each of the wells scheduled pursuant to the Development Plan to be drilled during such Non-Consent Year (such wells proposed where drilling operations are commenced, the “Non-Consent Wells”). For clarity, the Electing Party shall not be required to drill any or all of the Non-Consent Wells and it can choose which Non-Consent Well(s) to drill during such Non-Consent Year and when such Non-Consent Wells should be drilled.

(iii)The Electing Party will have the right to become operator with respect to any Non-Consent Wells commenced during the Non-Consent Year (including becoming operator with respect to any Non-Consent Wells commenced in the Non-Consenting Party's Operated Area). The Non-Consenting Party will use commercially reasonable efforts to assist the Electing Party to become operator with respect to such Non-Consent Wells. The Non-Consenting Party will also serve as a contract operator for the Electing Party, if the Electing Party is unable to takeover as operator with respect to any Non-Consent Well where the Non-Consenting Party is already designated as operator. The Non-Consenting Party will transfer to the Electing Party those agreements that the Electing Party needs to operate such Non-Consent Wells or, if such agreements are not transferable, hold such agreements for the benefit of the Electing Party.

(iv)With respect to each Non-Consent Well that is commenced during the Non-Consent Year, the non-consent penalties set forth in the Applicable Operating Agreement for such Non-Consent Well shall be applicable to the Non-Consenting Party.

(v)The Non-Consenting Party shall be solely responsible for any payment requirements (the “Non-Terminable Contract Obligations”) resulting from the Parties not satisfying their obligations under any non-terminable (without fee payment) contract relating to the Subject Assets during the Non-Consent Year (the “Non-Terminable Contracts”); provided that if in connection with its Development Operations during the Non-Consent Year the Electing Party does not actually incur at least an amount equal to 67% of the actual costs and expenses relating to drilling and completing wells that such Electing Party was projected to incur (after taking into account Noble's obligation to pay the Carried Costs for such wells) pursuant to the Annual Plan and Budget for such Non-Consent Year (being the Annual Plan and Budget deemed approved pursuant to Section 3.3(g)), then, within 15 days following the end of such Non-Consent Year, the Electing Party shall reimburse the Non-Consent Party for its Participating Interest share of all actual amounts paid by the Non-Consenting Party with respect to the Non-Terminable Contract Obligations and shall thereafter be responsible for paying its Participating Interest share of all Non-Terminable Contract Obligations. During a Non-Consent Year, the Parties shall each use their commercially reasonable efforts to mitigate any payment requirements under any Non-Terminable Contracts at the sole cost and expense of the Non-Consent Party; provided that the Electing Party shall not be required to conduct any Development Operations to satisfy its obligations to mitigate such payment requirements.

(vi)In the event that any wells scheduled pursuant to the Development Plan for such Non-Consent Year are not Non-Consent Wells, then the Development Plan shall automatically be amended to add such wells that are not Non-Consent Wells to the Development Plan to be conducted in the year following the year in which the Development Plan would have otherwise expired and the Development Plan shall be automatically extended for such period of time as is reasonably necessary for the applicable Party Operator to conduct such Development Operation.

(b)    Carried Costs. If Noble is the Non-Consenting Party, then:

(i)On or prior to January 1 of the Non-Consent Year, Noble must advance to the Tax Partnership Account designated and controlled (subject to the obligation of CONSOL to withdraw such funds only to pay for specific costs of the Non-Consent Year's drilling program) by CONSOL (the “Non-Consent Account”) the total amount of the Carried Costs that are contemplated by the Development Plan for the Non-Consent Year (the “Carried Costs Amount”), which funds may thereafter be solely utilized for the purposes described in Section 3.5(b)(ii) or 3.5(c)(ii). The Parties acknowledge that such funds in the Non-Consent Account discharge Noble's obligations to pay Carried Costs during such Non-Consent Year. Notwithstanding the fact that Noble has no right to the return of such funds once they are paid into such Non-Consent Account, interest in such funds shall be allocated and distributed 50% to CONSOL and 50% to Noble. Except for payment under this Section 3.5(b) of the Carried Costs Amount, Noble shall have no other obligation to pay any Carried Costs during the Non-Consent Year.

(ii)With respect to any Non-Consent Well or any other well proposed by a Third Party under an Applicable Operating Agreement that is actually spudded during the Non-Consent Year in which CONSOL participates, notwithstanding anything in Section 7.1(b) to the contrary, CONSOL shall pay out of the Non-Consent Account (until expended) two-thirds of CONSOL's Working Interest share of all Drilling and Completion Costs with respect to such wells (and all such Drilling and Completion Costs that are funded pursuant to this Section 3.5(b)(ii) shall be deemed to be Carried Costs for all purposes hereunder).

(iii)The provisions of Section 7.1(d) shall not be applicable during any Non-Consent Year.

(c)    Following a Non-Consent Year.

(i)To the extent that any Non-Consent Wells were commenced by the Electing Party in the Operated Area of the Non-Consenting Party, then the Non-Consenting Party will take over as operator with respect to each such Non-Consent Well as promptly as practicable following the later to occur of (A) the end of such Non-Consent Year and (B) the date upon which all drilling and completion operations with respect to such Non-Consent Well have been completed, and the Electing Party will use commercially reasonable efforts to assist the Non-Consenting Party to become operator with respect to each such Non-Consent Well.

(ii)If any portion of the Carried Costs Amount is not fully used to pay the costs set forth in Section 3.5(b) during the Non-Consent Year, then following such Non-Consent Year the funds remaining in the Non-Consent Account shall be used to satisfy Noble's obligation to pay Carried Costs and Noble shall not have any obligation to pay any additional amounts in respect of the Carried Costs incurred in following years until all such funds have been so expended.

(d)    Limited Right. Neither Noble nor CONSOL may exercise its Non-Consent Right if such Party also exercised its Non-Consent Right with respect to the calendar year immediately preceding the Non-Consent Year. A Party shall only be permitted to exercise the Non-Consent Right twice during the term of this Agreement.

4.1Restrictions on Transfer.

  

(a)Transfers by CONSOL and its Affiliates.

(i)Subject to Sections 4.1(c) through (f), 4.2, 4.3 and 4.4, prior to the thirty-month anniversary of the Closing Date, CONSOL shall not, and shall cause any of its Affiliates holding any Joint Development Interest not to, Transfer all or any portion of their Joint Development Interests (other than a Transfer of an Immaterial Interest) or undergo a Change in Control without the prior written consent of Noble (which may be granted or withheld in Noble's sole discretion).

(ii)Subject to Sections 4.1(c) through (f), 4.2, 4.3 and 4.4, from and after the thirty-month anniversary of the Closing Date, CONSOL and its Affiliates holding any Joint Development Interest shall be permitted to Transfer all or any undivided portion of their Joint Development Interests to any Person that as of the date of such Transfer has the financial ability to perform the future payment obligations hereunder and under the Associated Agreements with respect thereto, or undergo a Change in Control; provided that upon a Transfer where CONSOL intends that the transferee will become CONSOL Operator or upon such a Change in Control, Noble Operator shall be entitled to take over as CONSOL Operator under this Agreement and each Applicable Operating Agreement unless such transferee establishes to Noble's reasonable satisfaction that it has the technical ability and experience to serve as CONSOL Operator.

(b)Transfers by Noble and its Affiliates.

(i)Subject to Sections 4.1(c) through (f), 4.2, 4.3 and 4.4, prior to the later to occur of: (A) the thirty-month anniversary of the Closing Date and (B) the Carry Termination Event Noble shall not, and shall cause any of its Affiliates holding any Joint Development Interest not to, Transfer all or any portion of their Joint Development Interests (other than a Transfer of an Immaterial Interest) and Noble shall not permit any of its Affiliates holding any Joint Development Interest to undergo a Change in Control unless

the prior written consent of CONSOL to such otherwise prohibited Transfer or Change in Control (which may be granted or withheld in CONSOL's sole discretion) is first obtained.

(ii)Subject to Sections 4.1(c) through (f), 4.2, 4.3 and 4.4, from and after the later to occur of: (A) the thirty-month anniversary of the Closing Date and (B) the Carry Termination Event, Noble and its Affiliates holding any Joint Development Interest shall be permitted to Transfer all or any undivided portion of their Joint Development Interests to any Person that as of the date of such Transfer has the financial ability to perform the future payment obligations hereunder and under the Associated Agreements with respect thereto, or undergo a Change in Control; provided that upon a Transfer where Noble intends that the transferee will become Noble Operator or upon such a Change in Control, CONSOL Operator shall be entitled to take over as Noble Operator under this Agreement and each Applicable Operating Agreement unless such transferee establishes to CONSOL's reasonable satisfaction that it has the technical ability and experience to serve as Noble Operator.

(c)Permitted Transfers. Notwithstanding the restrictions on Transfer set forth in Sections 4.1(a) or 4.1(b), but subject to the requirements of Sections 4.1(e) and 4.2, (i) any Party and its Affiliates may Transfer all or an undivided portion of their Joint Development Interests (including the Tax Partnership) to any Affiliate of any Party (provided such Affiliate will be bound by all the provisions hereof as if it was the original party hereto), (ii) CONSOL and its Affiliates may encumber all or a portion of their Joint Development Interests solely for financing purposes and (iii) Noble and its Affiliates may encumber all or a portion of their Joint Development Interests that have become Developed Assets solely for financing purposes; provided, however, that no such Transfer of any Joint Development Interests as permitted under this Section 4.1(c) shall relieve such transferring Person of any of its or its Affiliates' obligations under this Agreement or, unless specifically provided otherwise, any Associated Agreement (whether accruing prior to or after the date of such Transfer). Notwithstanding Sections 4.1(a), 4.1(b) or 4.1(d) to the contrary, any Transfer by a Party to an Affiliate of such Party shall be deemed pursuant to and subject to this Section 4.1(c).

(d)Liability of Transferor/Transferee.

(e)Transfers by Defaulting Parties. No Defaulting Party may, and any Defaulting Party shall cause its Affiliates not to, Transfer all or any part of its Joint Development Interest or undergo a Change in Control unless and until the Total Amount in Default is paid by such Defaulting Party or its transferee or any other Person on behalf of such Defaulting Party and then further subject to compliance with the other provisions of this ARTICLE IV.

(f)Transfers in Violation of this ARTICLE IV. Any Transfer or attempted Transfer or Change in Control in violation of this ARTICLE IV shall be, and is hereby declared, null and void ab initio.

4.2Documentation for Transfers. Any Transfer (other than a Transfer of an Immaterial Interest or a Transfer permitted under Section 4.1(c)(i)) by any Party that is otherwise permitted pursuant to Section 4.1 shall not be effective unless and until the other Parties have received a document executed by both the transferring Party (or its legal representative) and the permitted transferee (or its legal representative) that includes: (a) the notice address of the permitted transferee; (b) such permitted transferee's express agreement

in writing to (i) be bound by all of the terms and conditions of this Agreement and any applicable Associated Agreement and (ii) assume an undivided interest (in an amount equal to the Participating Interest being Transferred to the permitted transferee) of all of the liabilities and obligations of the transferring Party under this Agreement and any applicable Associated Agreements (which may be limited to the liabilities and obligations arising from and after the effective time of the assignment); (c) a description of the Participating Interests in the Subject Assets being Transferred by the transferring Party and the permitted transferee immediately following the Transfer; and (d) representations and warranties to the other Parties from both the transferring Party and the permitted transferee that the Transfer was made in accordance with applicable Law (including state and federal securities Law) and the terms and conditions of this Agreement and any applicable Associated Agreements. Each permitted Transfer shall be effective against the other Parties as of the first Business Day of the calendar month immediately following the other Parties' receipt of the document required by this Section 4.2.

4.3Maintenance of Uniform Interest. For the purpose of maintaining uniformity of ownership in the Development Area as among the Parties, from and after the Closing Date during the term of this Agreement, no Party shall Transfer any portion of its Joint Development Interest (other than a Transfer of an Immaterial Interest or a Transfer permitted under Section 4.1(c)(i)) unless such Transfer covers the entirety of such Party's Joint Development Interest, or an undivided percentage thereof. Any Transfer of an undivided portion of a Party's Joint Development Interest shall also include a proportionate share of the transferring Party's rights and obligations in and under this Agreement and any applicable Associated Agreement.

4.4Right of First Offer.

(a)Subject to Section 4.1, if a Party or any of its Affiliates (each such Person, a “Transferor”) desires to Transfer to a Third Party (either directly or indirectly through a Change in Control but excluding Transfers of the types described in Section 4.1(c) and a Transfer of an Immaterial Interest) all or any portion of the Transferor's Joint Development Interest, the Transferor shall give to the other Parties (the “ROFO Parties”) written notice (“ROFO Notice”) stating the Transferor's desire to effect such Transfer, the Joint Development Interest to be Transferred (the “Offered Interest”) and the terms and conditions on which the Transferor proposes to Transfer the Offered Interest; provided, however, that if the consideration set forth in such ROFO Notice contemplates any non-cash consideration, the ROFO Parties shall be entitled to pay in lieu of such non-cash consideration, cash in an amount equal to the Fair Market Value of such non-cash consideration unless the ROFO Parties and Transferor agree to some other form of consideration. The ROFO Parties shall have the right but not the obligation to elect to acquire such Offered Interest on the terms and conditions set forth in the ROFO Notice. The ROFO Notice shall constitute a binding offer (the “ROFO Offer”) by the Transferor to Transfer to the ROFO Parties the Offered Interest at the price and upon the terms specified in the ROFO Notice and such offer shall be irrevocable for 30 days following receipt by the ROFO Parties. Any ROFO Party may accept such ROFO Offer and acquire all but not less than all of the Offered Interest by giving written notice of the same to the Transferor within such 30-day period; provided that if more than one ROFO Party accepts such ROFO Offer then, unless such ROFO Parties otherwise agree, each ROFO Party shall acquire a pro rata portion of the Offered Interest based on the relative Participating Interests of each accepting ROFO Party. The failure by any ROFO Party to so notify the Transferor within such 30-day period shall be deemed an election by such ROFO Party not to accept such ROFO Offer.

(b)If one or more ROFO Parties accepts the ROFO Offer, then the Transferor and such accepting ROFO Parties shall cooperate together to consummate the Transfer of the Offered Interest to the ROFO Parties as promptly as practicable following such acceptance.

(c)If none of the ROFO Parties accepts the ROFO Offer, then the Transferor may Transfer all

but not less than all of the Offered Interest at any time within 180 days following the end of the 30-day period that the ROFO Parties had to accept the ROFO Offer. Any such Transfer shall be at a price not less than the price set forth in the ROFO Notice and on such other terms and conditions not more favorable in any material respect to the acquiring party than those specified in the ROFO Notice. If the Transferor does not affect such Transfer within such 180-day period, the Transfer of the Offered Interest shall again become subject to the right of first offer set forth in this Section 4.4.

5.1Creation of Area of Mutual Interest. Subject to Section 10.2(5), the Parties agree that for a period beginning on the Closing Date and ending on the 25th anniversary thereof, the Development Area shall be an area of mutual interest as described in Exhibit A-1. For clarity, in general this Agreement only applies to Subject Assets covering depths within the Marcellus Formation, but with respect to any Fill-In Interest or Option Interest to be acquired pursuant to this ARTICLE V, such Fill-In Interest and/or Option Interest shall include all depths that have been or are being acquired by the acquiring Party or Acquiring Party, as applicable. In the event a Fill-In Interest or an Option Interest is acquired pursuant to this ARTICLE V, only the portion of such Fill-In Interest or Option Interest that covers depths within the Marcellus Formation shall thereafter be subject to the terms and provisions of this Agreement and the depths outside the Marcellus Formation shall not be subject to the terms of this Agreement. Further for clarity, if a Party or any of its Affiliates, directly or indirectly, acquires a Lease or related asset in the Development Area that does not cover any depths within the Marcellus Formation, then such acquisition shall not be subject to the terms of this ARTICLE V or the other terms of this Agreement.

5.2Acquisition of Fill-In Interests for Drilling Units in the Development Area. Although it is anticipated that only a Party Operator will acquire Fill-In Interests in such Party Operator's Operated Area, if, after the date hereof, any Party or any of its Affiliates, directly or indirectly (including by merger, acquisition of equity or otherwise), acquires any additional Leases and related assets within the Development Area covering at least depths within the Marcellus Formation that completes or increases their Working Interest in a Drilling Unit covering existing Subject Assets (a “Fill-In Interest”), then such Party will promptly provide written notice to the other Parties of such acquisition, including the material terms and conditions of such acquisition (excluding any terms dealing solely with assets not within the Development Area). Within 30 days after such notice is delivered to the other Parties, such other Parties shall purchase their individual Participating Interest share of such Fill-In Interests from such acquiring Party or its Affiliate. At the closing of such purchase, (a) each purchasing Party will be required to (i) except for obligations assumed pursuant to clause (ii) below, pay in cash to the acquiring Party (or its Affiliate) its Participating Interest share of the Acquisition Costs that the acquiring Party (or its Affiliate) incurred in acquiring such Fill-In Interest, together with interest thereon at the Agreed Rate from the date on which the acquiring Party (or its Affiliate) acquired the Fill-In Interest to the date of such payment and (ii) if the Fill-In Interest is acquired pursuant to a farmout agreement or similar agreement requiring the drilling of a well or the performance of other similar obligations, subject to Section 7.1, assume its Participating Interest share of all obligations required to be performed by the applicable acquiring Party or its Affiliates to earn such Fill-In Interest and (b) the acquiring Party (or its Affiliate) shall deliver to such other Parties their respective individual Participating Interest share of the Fill-In Interests on the same terms and conditions as the acquiring Party (or its Affiliate) acquired the Fill-In Interests (with such changes as may be necessitated by the differences in the parties, the transfer of only the Fill-In Interests and, if applicable, the payment of the Fair Market Value in lieu of other consideration or the apportionment of rights from a Package Sale); provided that, except for a special warranty of title covering the acquiring Party's (or its Affiliate's) period of ownership, the acquiring Party shall in no event have any

liability to the other Parties for representations, warranties or indemnities with respect to the Fill-In Interest in excess of the Parties' Participating Interest shares of amounts that the acquiring Party (or its Affiliate) actually recovers from the Person from whom it acquired the Fill-In Interest. The costs of recording the assignment of each Party's interest in Fill-In Interests in the real property records of the appropriate county or township as applicable shall be chargeable to the joint account under the Applicable Operating Agreement.

5.3Acquisition of Option Interests in the Development Area.  

(a)If, after the date hereof, a Party or any of its Affiliates, directly or indirectly (including by merger, acquisition of equity or otherwise), acquires or seeks to acquire any additional Leases and related assets within the Development Area covering at least depths within the Marcellus Formation (other than any Fill-In Interest) (such Person, the “Acquiring Party”), then the Acquiring Party (i) will in the case of any acquisition that has already taken place and (ii) may in the case of any proposed acquisition promptly provide written notice (the “Acquisition Notice”) to the other Parties (the “Non-Acquiring Parties”) of such acquisition or proposed acquisition, as applicable, including the material terms and conditions (excluding any terms dealing solely with assets not within the Development Area) of such acquisition and a description of the Leases and related assets that are being or has been acquired (the “Option Interests”). Within 30 days after such Acquisition Notice is delivered to the Non-Acquiring Parties (the “Election Period”), the Non-Acquiring Parties will have the option to acquire (i) all, but not less than all, of their Participating Interest share of such Option Interests and (ii) all, but not less than all, of their Participating Interest share of any portion of the Option Interests that any Non-Acquiring Parties elect not to acquire in accordance with this Section 5.3(a), in each case, on the same terms and conditions on which the Acquiring Party acquired or will acquire the Option Interests by providing written notice of such election to the Acquiring Party. If a Non-Acquiring Party fails to exercise its option within such 30-day period, such Non-Acquiring Party shall be deemed to have made an election not to participate.

(b)If any of the Non-Acquiring Parties elect to participate in accordance with Section 5.3(a), such Non-Acquiring Parties shall purchase their share of the Option Interests from the Acquiring Party within 30 days of its election in the case of any acquisition that has already taken place, or in the case of a proposed acquisition, at the closing of such acquisition (or as promptly as practicable thereafter as the Acquiring Party may reasonably determine) (such date, the “Payment Date”). At the closing of such purchase (an “AMI Purchase Date”), (i) such Non-Acquiring Parties will be required to (A) except for obligations assumed pursuant to clause (B) below, pay to the Acquiring Party (or to such other Person as the Acquiring Party may designate) its share of the Acquisition Costs in proportion to the interest in the Option Interests it is acquiring in cash, together with interest thereon at the Agreed Rate from the date on which the Acquiring Party acquired the Option Interests (if earlier than the Payment Date) to the Payment Date and (B) if the Option Interest is acquired pursuant to a farmout agreement or similar agreement requiring the drilling of a well or the performance of other similar obligations, subject to Section 7.1, assume its share of all obligations required to be performed by the Acquiring Party or its Affiliates to earn such Option Interest and (ii) the Acquiring Party shall deliver to such Non-Acquiring Parties their respective interests in the Option Interests on the same terms and conditions as such Acquiring Party is or has acquired its interest in the Option Interests (with such changes as may be necessitated by the differences in the parties, the transfer of only the Option Interests and, if applicable, the payment of the Fair Market Value in lieu of other consideration or the apportionment of rights from a Package Sale); provided that, except for a special warranty of title covering the Acquiring Party's period of ownership, the Acquiring Party shall in no event have any liability to the Non-Acquiring Parties for representations, warranties or indemnities with respect to the Option Interest in excess of the Non-Acquiring Parties' Participating Interest shares of amounts that the Acquiring Party actually recovers from the Person from whom it acquired the Option Interest. Each Non-Acquiring Party will be responsible for and will pay the costs of recording the assignment of its interest in the Option Interests in the real property

records of the appropriate county or township as applicable.

(c)If all of the Non-Acquiring Parties elect not to participate in accordance with Section 5.3(a), the Acquiring Party will retain 100% of the Option Interests and such Option Interests will be excluded from the Development Area and will not be governed by the terms of this Agreement or any Applicable Operating Agreement.

(d)If an Acquiring Party acquires or seeks to acquire any Lease that lies partially within and partially outside of the Development Area, then the entirety of such Lease shall be deemed to be an Option Interest and if one or more Non-Acquiring Parties elects to acquire an interest in such Lease, the Development Area (and the applicable Operated Area to which such Lease relates) shall automatically be amended to include the entirety of such Lease. The Parties shall memorialize in writing any such amendment to the Development Area and any Operated Area.

(e)For avoidance of doubt, the Additional Interests shall be treated as “Fill-In Interests” or “Option Interests,” as applicable, for purposes of this Agreement in accordance with the Acquisition Agreement, and CONSOL shall offer the Additional Interests to Noble within 15 days following the Closing Date in accordance with the terms of this Section 5.3.

(f)Each Party shall cause its Affiliates to comply with the terms of this ARTICLE V.

5.4Exceptions.

  

(a)Notwithstanding anything in this ARTICLE V to the contrary, the provisions of this ARTICLE V shall not apply to (i) any acquisition of a Lease or related asset by CONSOL or its Affiliates for the purpose of curing a title defect in accordance with the Acquisition Agreement or (ii) any indirect acquisition by a Party or its Affiliates of any Lease and related assets by the acquisition of an entity having at least 75% (by Fair Market Value) of its assets outside of the Development Area; provided that such indirect acquisition of such Lease(s) and related assets is not made with the intention of circumventing the provisions of this Article V.

(b)Notwithstanding anything in this ARTICLE V to the contrary, in the event that, during the period in which the provisions of this ARTICLE V are applicable to the Parties, a Party or its Affiliates acquires more than $50,000,000 (by Fair Market Value) of Option Interests, in a single transaction or series of related transactions, in exchange for cash or assets and the Acquiring Party specifies in its Acquisition Notice that such Acquiring Party is acquiring such Option Interest through a like kind exchange (as provided for under Section 1031 of the Internal Revenue Code of 1986, as amended and the regulations thereto), then the following provisions of this Section 5.4(b) shall also apply to such acquisition (and to the extent of any conflict between Section 3.5 and this Section 5.4(b), this Section 5.4(b) shall control):

(i)The Election Period shall not begin until the Acquiring Party provides the Non-Acquiring Parties with written notice in accordance with this Section 5.4(b)(i), which the Acquiring Party shall be required to provide to the Non-Acquiring Parties within 5 Business Days following the end of the 3-month anniversary of the date on which such Party and/or Affiliate completes such like kind exchange. Such notice from the Acquiring Party to the Non-Acquiring Parties shall include (A) the material terms and conditions (excluding any terms dealing solely with assets not within the Development Area) of such acquisition, (B) a description of the Option Interests, (C) a description of all drilling, completing, deepening, sidetracking, reworking and plugging and abandoning operations that have been conducted with respect to the Option Interests since the Acquiring Party acquired such Option Interests or are contemplated to be

completed through the end of the Election Period, (D) copies of all written notices of claims made by or against the Acquiring Party relating to the Option Interests, (E) copies of all environmental assessment in the possession of or under the control of the Acquiring Party relating to the Option Interests and (F) an estimated preliminary settlement statement reflecting the Acquisition Costs of the Option Interests (as adjusted pursuant to Section 5.4(b)(ii).

(ii)If the Non-Acquiring Parties elect to participate in accordance with Section 5.3(a), then on the AMI Purchase Date, (A) such Non-Acquiring Parties will be required to pay to the Acquiring Party (or to such other Person as the Acquiring Party may designate) its share of the Acquisition Costs in proportion to the interest in such Option Interests it is acquiring in cash (with such adjustments to such Acquisition Costs (including capital expenditures and lease operating expenses) as may be necessitated by the fact that development and other operations may have occurred with respect to such Option Interests since the date such Option Interests were acquired by the Acquiring Party) and (B) the Acquiring Party shall deliver to such Non-Acquiring Parties their respective interests in such Option Interests with special warranty of title by, through and under the Acquiring Party and otherwise on the same terms and conditions as such Acquiring Party is or has acquired its interest in such Option Interests (with such changes as may be necessitated by the differences in the parties, the fact that operations have occurred with respect to such Option Interests, the transfer of only such Option Interests and, if applicable, the payment of the Fair Market Value in lieu of other consideration or the apportionment of rights from a Package Sale).

(iii)The Non-Acquiring Parties shall not be charged any interest on the Acquisition Costs.

(iv)Beginning on the date that such Option Interests are acquired by the Acquiring Party until the earlier of (A) the AMI Purchase Date and (B) the date upon which the Non-Acquiring Party elects (or is deemed to have elected) not to participate (the “Restricted Period”), each Non-Acquiring Party shall be entitled to receive the same reports and information relating to, and shall have the same access to, such Option Interests as if such Option Interests were Subject Assets hereunder and such Non-Acquiring Party held an interest therein (including all AFEs required by Section 3.4).

(v)During the Restricted Period, except as permitted under this ARTICLE V, the Acquiring Party shall not, and shall cause its Affiliates not to, Transfer all or any portion of the Option Interests to any Person.

(vi)During the Restricted Period, the Acquiring Party shall, and shall cause its Affiliates to, consult with the Non-Acquiring Party prior to conducting any drilling operations on the Option Interests (other than drilling operations that have been commenced prior to the Acquiring Party's acquisition of the Option Interests).

(vii)For clarity, the “Option Interests” as used in this Section 5.4(b) shall include any improvements made to, or equipment or other property acquired by, such Acquiring Party in connection with any operations conducted upon the Leases included in the Option Interests after the date the original Option Interests are acquired by such Acquiring Party.

(viii)Unless and until the AMI Purchase Date occurs, only the Acquiring Party (and not the Non-Acquiring Parties) shall be entitled to the benefits and burdens of the Option Interests.

6.1Tax Partnership. The Parties intend and expect that the transactions contemplated by the Acquisition Agreement, this Agreement and the Associated Agreements, taken together, will be treated, for purposes of federal income taxation and for purposes of certain state income tax laws that incorporate or follow federal income tax principles (“Tax Purposes”), as resulting in the creation of a partnership (the “Tax Partnership”) in which Noble and CONSOL are treated as partners. Accordingly, for Tax Purposes, (a) the Tax Partnership will be treated as (i) holding (A) the Parties' interests in Oil and Gas Assets, (B) any other Subject Assets and (C) any cash held in any account identified or otherwise treated as being an asset of the Tax Partnership resulting from production or contribution pursuant to the Asset Acquisition Agreement or this Agreement and (ii) engaging in all activities of the Parties with respect to the Subject Assets, (b) CONSOL will be treated as contributing to the Tax Partnership at Closing of the Oil and Gas Assets and its undertaking to fund, when due, the costs and expenses allocable to it under this Agreement in exchange for an interest in the Tax Partnership; (c) Noble will be treated as contributing to the Tax Partnership at Closing (by deposit into the Cost Reconciliation Account) the Closing Cash Payment (as adjusted), its undertaking to fund, when due, the Post Closing Cash Payments and the costs and expenses allocable to it under this Agreement (including the Carried Costs, any Carried Costs Amount and any Carried Costs Balance Payments) in exchange for an interest in the Tax Partnership; (d) upon any withdrawal by CONSOL (as and to the extent permitted under Section 7.6 hereof) of the Total Cost Sharing Payments from the Cost Reconciliation Account, CONSOL will be treated as receiving distributions from the Tax Partnership of the withdrawn amounts (i) as a reimbursement of CONSOL's preformation expenditures with respect to the Oil and Gas Assets within the meaning of Treasury Regulations Section 1.707-4(d) to the extent applicable and (ii) in a transaction subject to treatment under Section 707(a) of the Internal Revenue Code of 1986, as amended, and its implementing Treasury Regulations as in part a sale, and in part a contribution, of the Oil and Gas Assets to the Tax Partnership to the extent that Treasury Regulations Section 1.707-4(d) is inapplicable, and (e) from and after its commencement, the Tax Partnership will be treated as realizing all items of income or gain and incurring all items of cost or expense attributable to the ownership, operation or disposition of the Subject Assets, notwithstanding that such items are realized, paid or incurred by the Parties individually. The governing terms and conditions of the Tax Partnership are set forth in Exhibit G hereto.

6.2Tax Information. Each Party Operator shall provide the TRP (as defined in the Tax Partnership Agreement) or each Party, as applicable, in a timely manner and at each Party's sole expense, with information with respect to Development Operations and Area-Wide Operations conducted by such Party Operator as the TRP or such Party may reasonably request for preparation of its tax returns, responding to any audit or tax proceeding with respect to Asset Taxes or complying with the reporting obligations in the Tax Partnership Agreement.

6.3Responsibility for Taxes. Each Party shall be responsible for reporting and discharging its own tax measured by the income of the Party and the satisfaction of such Party's share of all contract obligations under this Agreement, the Associated Agreements and the Tax Partnership Agreement. Each Party shall protect, defend, and indemnify each other Party from and against any and all losses, costs, and liabilities arising from the indemnifying Party's failure or refusal to report and discharge such taxes or satisfy such obligations.

7.1Payment of Development Costs and Carried Costs.

(a)Subject to the other terms of this Agreement including Section 7.1(b) and subject to the applicable Annual Plan and Budget, (i) Noble shall pay its Share of Development Costs and (ii) CONSOL shall pay its Share of Development Costs.

(b)In addition to paying for its Share of Development Costs, unless the following obligation is temporarily suspended pursuant to Section 7.1(d), during the Carry Period (notwithstanding the terms of any Applicable Operating Agreement to the contrary) Noble shall pay, on behalf of CONSOL and its Affiliates, one-third of all Drilling and Completion Costs that CONSOL would otherwise be required to pay as its Share of Development Costs under Section 7.1(a) (all such Drilling and Completion Costs that Noble is obligated to pay pursuant to this Section 7.1(b) and subject to Section 3.5, the “Carried Costs”). For clarity, the Parties intend that Noble shall pay its Share of Development Costs plus all Carried Costs until the Carry Termination Event, and that CONSOL shall pay its Share of Development Costs less all Carried Costs until the Carry Termination Event.

(c)Until the Carry Termination Event, all Carried Costs shall be paid by Noble in the same manner and at the same time it pays or advances its Share of Development Costs pursuant to Section 7.2.

(d)Unless otherwise agreed by Noble in writing and except as provided in Section 3.5(b)(iii), Noble's obligation to pay, on behalf of CONSOL and its Affiliates, the Carried Costs shall be temporarily suspended (i) during any period beginning on the first date in any calendar year that the Carried Costs paid by Noble for Drilling and Completion Costs incurred in such calendar year exceeds $400,000,000 and ending on the last day of such calendar year and (ii) during any period (A) beginning on the first day of the month following the month in which the average midpoint price per MMBtu of natural gas (as reported by Platts Gas Daily for natural gas delivered at Henry Hub for each such day) for a calendar month and the preceding two calendar months before such month is less than $4.00/MMBtu and (B) ending on the first day of the month following the month in which the average midpoint price per MMBtu of natural gas (as reported by Platts Gas Daily for natural gas delivered at Henry Hub for each such day) for a calendar month and the preceding two calendar months before such month equals or exceeds $4.00/MMBtu.

(e)Under no circumstance shall Noble be permitted to offset any amounts owed by CONSOL to Noble against Noble's obligation to pay the Carried Costs or the Post Closing Cash Payments.

7.2Payment Procedures.

  

(a)Each Party Operator, at its option, may issue statements and invoices to any Party for such Party's Share of Development Costs (after giving effect to Section 7.1(b)) and, in the case of Noble, the Carried Costs that such Party Operator incurs in connection with Development Operations or may issue a request to any Party to advance such Party's Share of Development Costs and, in the case of Noble, the Carried Costs that such Party Operator reasonably anticipates to be incurred in the future in connection with Development Operations; provided that no Party shall be obligated to advance any monies hereunder to such Party Operator for costs more than 30 days before such Development Costs are reasonably anticipated to be incurred by such Party Operator.

(b)Subject to the proviso in Section 7.2(a), in response to each statement or invoice for

Development Costs issued by a Party Operator pursuant to Section 7.2(a), each Party shall pay or advance its Share of Development Costs and, in the case of Noble, the Carried Costs within 15 days of receiving such statement or invoice.

(c)In response to each statement or invoice for Development Costs issued by a Third Party Operator under an Applicable Operating Agreement (to the extent a Party Operator has not previously issued a statement or invoice for such Development Costs), subject to the applicable Annual Plan and Budget, each Party shall pay its Share of Development Costs (after giving effect to Section 7.1(b)). In the event that a Party Operator has issued a statement or invoice for Development Costs and a Third Party Operator under an Applicable Operating Agreement issues a statement or invoice for the same Development Costs, (i) subject to the applicable Annual Plan and Budget (as modified by Section 3.3(i)), each Party shall pay or advance its Share of Development Costs (after giving effect to Section 7.1(b)) by the earlier of (x) the date such amounts are required to be paid or advanced pursuant to such Party Operator's statement or invoice and (y) one Business Day prior to the date such amounts are required to be paid or advanced pursuant to such Third Party Operator's statement or invoice and (ii) upon receipt of such payment or advance, such Party Operator shall pay, on behalf of each Party, such operator for such Development Costs.

(d)Each Party shall have the right to audit each Party Operator's and its Affiliates' accounts with respect to Development Operations and Area-Wide Operations in which it participates on the same basis as is provided in Exhibit “C” to the Master JOA.

7.3Carried Costs Balance Payment. At any time from and after the thirty-month anniversary of the Closing Date until the Carry Termination Event, Noble, upon five Business Days written notice to CONSOL (the “Balance Election Notice”), shall have the right (but not the obligation) to elect to pay the Carried Costs Balance as a lump sum payment, as applicable (such payment, the “Carried Costs Balance Payment”). Promptly following the delivery of the Balance Election Notice by Noble, but in any event within five Business Days following such delivery, Noble shall pay the Carried Costs Balance Payment by wire transfer of immediately available funds to the Carried Cost Balance Account designated and controlled (subject to the obligations of CONSOL to withdraw such funds solely for the purpose hereafter described) by CONSOL promptly following CONSOL's receipt of the Balance Election Notice. Upon CONSOL's receipt of the Carried Costs Balance Payment, Noble's and its Affiliates' obligation to pay Carried Costs shall be deemed to be fully satisfied, the Carry Termination Event shall be deemed to have occurred and Noble shall have no right to the return of the Carried Cost Balance. Notwithstanding anything in this Agreement to the contrary, any funds held in the Carried Costs Balance Account (exclusive of interest, which notwithstanding the fact that the payment of the requisite funds into the Carried Costs Balance Account, shall be allocated and distributed 100% to Noble) shall, prior to the termination of the Tax Partnership pursuant to Section 7.1 of the Tax Partnership Agreement, be used solely to pay Drilling and Completion Costs of CONSOL incurred pursuant to Development Operations and Area-Wide Operations in the same amount and manner as the funds provided by Noble to pay Carried Costs in accordance with Section 7.1(b) would have been used pursuant to this Agreement had the Carried Costs Balance Payment not been made and the Carry Termination Event not occurred.

7.4Post Closing Cash Payments. Noble shall pay to CONSOL the Post Closing Cash Payments as and when required under the Acquisition Agreement.

7.5Certain Order of Payments. Notwithstanding anything in this Agreement to the contrary, each Party hereby agrees that with respect to any outstanding payment obligation of Noble, all monies received by CONSOL and all recoveries realized in connection with any of the remedies hereunder for a default by Noble shall first be applied towards any portion of the Post Closing Cash Payments that are then due and

payable by Noble to CONSOL, second, be applied towards any Carried Costs that are then due and payable by Noble, and third, be applied pro rata amongst the Parties towards any other payment obligations of Noble.

7.6Total Cost Sharing Payments. Noble shall pay the Total Cost Sharing Payments into the Cost Reconciliation Account designated and controlled (subject to the obligations of CONSOL to withdraw such funds solely for the purposes specified in this Section 7.6) by CONSOL as and when required under the Acquisition Agreement. The funds (other than interest accruing thereon) held from time to time in the Cost Reconciliation Account shall not be withdrawn or applied for the benefit of either Party for 30 days after the date on which such funds are deposited into the Cost Reconciliation Account (with respect to such funds, the “Lockup Termination Date”), provided that CONSOL shall be entitled to borrow any portion of the principal balance of the Cost Reconciliation Account prior to the relevant Lockup Termination Date applicable to the funds at an arm's-length interest rate and on other commercially reasonable terms for similar loans. The Parties acknowledge that the funds in the Cost Reconciliation Account discharge Noble's obligation to make Total Cost Sharing Payments dollar for dollar. Notwithstanding the fact that Noble has no right to the return of the Total Cost Sharing Payments paid into the Cost Reconciliation Account, any interest earned on the Cost Reconciliation Account (or loans made therefrom) shall be allocated and distributed to the Parties based on their respective Participating Interests periodically. Following the relevant Lockup Termination Date, the principal balance of the Cost Reconciliation Account shall be withdrawn by, and transferred to, CONSOL as reimbursement of costs funded by CONSOL in respect of the Oil and Gas Assets prior to the Closing Date (and not theretofore reimbursed from the Total Cost Sharing Payments).

8.1Defaults.  

(a)In the event that any Party fails to pay any of its Share of Development Costs (other than with respect to operational expenses, excluding Carried Costs, that are being disputed by a Party in good faith in an aggregate amount not to exceed $1,000,000) or Noble fails to pay any Carried Costs, in each case, on or before the Initial Default Date, or Noble fails to make any payment in respect of the Post Closing Cash Payments as and when required by Section 7.4 and under the Acquisition Agreement (such Party, a “Defaulting Party” and each such failure, a “Payment Default”), then (i) the other Parties (the “Non-Defaulting Parties”) shall provide written notice of such Payment Default (a “Default Notice”) to such Defaulting Party within 10 days after the Initial Default Date (provided any failure by the Non-Defaulting Parties to give such notice within such time period shall not affect any rights or remedies of the Non-Defaulting Parties in this Agreement, the Acquisition Agreement or any Associated Agreement, but shall be a covenant for the benefit of the Defaulting Party solely for the purpose of allowing the Defaulting Party to assert a claim in the event the Defaulting Party incurs damages caused by the Non-Defaulting Party's failure to give any such notice within such period) and (ii) in addition to (A) the remedies available to any Non-Defaulting Party under any Associated Agreements, (B) those remedies that occur automatically pursuant to Section 8.2, (C) in the case Noble is the Defaulting Party with respect to its payment obligations for the Post Closing Cash Payments, the remedies available to CONSOL under the Acquisition Agreement, and (D) any and all other rights and remedies under this Agreement or at Law or in equity, the applicable Non-Defaulting Parties shall be entitled to exercise, in their sole discretion, any one or more of the remedies set forth in Section 8.3 during the period of time beginning on the Initial Default Date until the date upon which the Total Amount in Default has been fully cured (the “Default Period”).

(b)All amounts in default and not paid when due under this Agreement shall bear interest at the Agreed Rate from the due date to the date of payment.

8.2Certain Automatic Remedies for a Default.  

(a)General Remedies. Unless a majority of the Non-Defaulting Parties (based on their relative Participating Interests) elect in writing to waive or extend the time period for any or all of the following, then, for a period (1) beginning on the earlier of (x) the 10^th day after the date on which the Defaulting Party receives the Default Notice and (y) 20 days after the Initial Default Date and (2) ending upon the expiration of the Default Period, the Defaulting Party shall automatically not be entitled to:

(i)make or elect to participate in any proposal under this Agreement or any Applicable Operating Agreement;

(ii)vote on any matter with respect to which approval is required under the express terms of this Agreement or any Associated Agreement (excluding any amendment or waiver of the terms of any such agreement and any amendment or modification to the Development Plan);

(iii)call any Joint Development Committee meeting;

(iv)send its representatives or advisors to any meeting of the Joint Development Committee (and such members shall not be eligible to vote on any matters brought before the Joint Development Committee);

(v)access any data or information relating to any operation conducted under this Agreement or any Associated Agreement (except to the extent that the Defaulting Party is a Party Operator, in which case such Defaulting Party shall be entitled to such data and information as may be necessary to perform its responsibilities in such capacity);

(vi)Transfer all or any part of its Joint Development Interest or any other Subject Asset, undergo a Change in Control or encumber all or any part of its Joint Development Interest or any other Subject Assets, except in a case of a Transfer of a Joint Development Interest to, or a Change in Control with, a Person or encumbrance in favor of a Person who simultaneously with such Transfer, Change in Control or encumbrance satisfies in full the Total Amount in Default;

(vii)elect to acquire any Offered Interest pursuant to Section 4.4; or

(viii)elect to acquire any Option Interests pursuant to Section 5.3.

(b)Certain Remedies. If Noble is a Defaulting Party with respect to the Total Amount (a “NBL Payment Default”), then unless CONSOL elects in writing to waive or extend the time period for the following, as of the earlier to occur of (x) the 110^th day after the date on which Noble, as the Defaulting Party, receives the Default Notice for such NBL Payment Default and (y) 120 days after the Initial Default Date for such NBL Payment Default (the “NBL Acceleration Trigger”), Noble shall be required to pay the NBL Balance as a lump sum payment, as applicable (such payment, the “NBL Balance Payment”). Promptly following the NBL Acceleration Trigger, but in any event within five Business Days following the date of such NBL Acceleration Trigger, Noble shall pay to CONSOL the NBL Balance Payment by wire transfer of immediately available funds as follows: (i) the amount of the Carried Costs Balance shall be paid to the Carried Costs Balance Account specified by CONSOL in writing to Noble promptly following the NBL Acceleration Trigger and (ii) the amount of the Post Closing Cash Payments Balance shall be paid to a Tax Partnership Account specified by CONSOL in writing to Noble promptly following the NBL Acceleration

Trigger. Upon CONSOL's receipt of the NBL Balance Payment, (a) Noble and its Affiliates shall be deemed to no longer be in default of the obligation to pay the Total Amount in accordance with this Agreement and the Acquisition Agreement, (b) such obligation to pay Total Amount shall be deemed to be fully satisfied, and (c) the Carry Termination Event shall be deemed to have occurred. Notwithstanding anything in this Agreement to the contrary, any funds held in the Carried Costs Balance Account (exclusive of interest, which shall be allocated and distributed 50% to CONSOL and 50% to Noble) shall, prior to the termination of the Tax Partnership pursuant to Section 7.1 of the Tax Partnership Agreement, be used solely to pay Drilling and Completion Costs incurred pursuant to Development Operations and Area-Wide Operations in the same amount and manner as the funds provided by Noble to pay Carried Costs would have been used pursuant to this Agreement had the NBL Balance Payment not been made and the Carry Termination Event not occurred.

8.3Certain Other Remedies for a Default.

  

(a)Right to Entitlements. From and after the 30^th day after the Initial Default Date, a Defaulting Party shall have no right to receive its Entitlement from the Subject Assets and the Non-Defaulting Parties shall have the right to collect such Entitlement; provided that, in the case that (i) Noble is the Defaulting Party, the proceeds from all such Entitlements shall be used to pay the Total Amount in Default and shall be deemed, first, to apply to the portion of the Total Amount in Default that relates to any portion of the Post Closing Cash Payments that are then due and payable by Noble to CONSOL, second, and only to the extent that all Payment Defaults have been cured with respect to the Post Closing Cash Payments, to apply to the portion of the Total Amount in Default that relates to any Carried Costs and, third, and only to the extent that all Payment Defaults have been cured with respect to the Post Closing Cash Payments and the Carried Costs, proportionately to the remainder of the Total Amount in Default and (ii) CONSOL is the Defaulting Party, the proceeds from all such Entitlements shall be used to pay the Total Amount in Default and shall be deemed to apply proportionately to the Total Amount in Default.

(c)Removal of Party Operator.

8.4Cumulative and Additional Remedies. The rights and remedies granted to Non-Defaulting

Parties in this ARTICLE VIII shall be cumulative, not exclusive, and shall be in addition to any other rights and remedies that may be available to the Non-Defaulting Parties, at Law, in equity or otherwise. Each right and remedy available to a Non-Defaulting Party may be exercised from time to time and so often and in such order as may be considered expedient by a Non-Defaulting Party in its sole discretion.

9.1Land and Geoscience Data. To the extent that a Party is neither prohibited nor required to make payment of a fee pursuant to any Third Party agreement or applicable Law, each Party will make available to any other Party, upon request, (a) all existing leasehold documentation developed or obtained by such Party in connection with the acquisition of Subject Assets within the Development Area, including all lease, land, title and division order files (including any available abstracts of title, title opinions and reports, and title curative documents), contracts, accounting records, correspondence, permitting, engineering, production, and well files (including any well logs) and (b) all seismic and geological data and other similar information, including drainage data, seismic surveys, information regarding fracing of wells and related information regarding the development and operation of the Subject Assets, in each case, that such Party may possess. The Party holding such data and information, as the case may be, will use its commercially reasonable efforts to obtain the consent of the applicable party to disclose any such data to such other Parties (to the extent applicable to such Parties' interest in the Subject Assets at such time) if such disclosure is otherwise prohibited without such consent. Other than with respect to amounts required to be paid to obtain any necessary consent to share any information that was held by CONSOL Operator prior to the Closing Date and amounts being paid by Noble to CONSOL pursuant to the Acquisition Agreement, the costs of acquiring, transferring or sharing any such data and information (including any fee amounts required to be paid to obtain any necessary consents) for any Subject Assets will be Development Costs to be borne and paid by the Parties in relation to their Participating Interests. With respect to amounts required to be paid to obtain any necessary consent to share any information that was held by CONSOL Operator prior to the Closing Date, such amount shall be paid by the Party requesting the sharing of such information.

EACH PARTY EXPRESSLY AGREES THAT ANY RELIANCE UPON OR CONCLUSIONS DRAWN FROM ANY MATERIALS, DOCUMENTS AND OTHER INFORMATION PROVIDED BY ANOTHER PARTY SHALL BE AT ITS OWN RISK TO THE MAXIMUM EXTENT PERMITTED BY LAW AND SHALL NOT GIVE RISE TO ANY LIABILITY OF OR AGAINST THE PROVIDING PARTY. EACH PARTY HEREBY WAIVES AND RELEASES ANY CLAIMS ARISING UNDER THIS AGREEMENT, COMMON LAW OR ANY STATUTE ARISING OUT OF ANY MATERIALS, DOCUMENTS OR INFORMATION PROVIDED BY ANOTHER PARTY TO SUCH PARTY. EACH PARTY agreeS that, to the extent required by applicable Law to be effective, the disclaimers of certain representations and warranties contained in this Section 9.2 are “conspicuous” disclaimers for the purpose of any applicable Law.

Notwithstanding the foregoing, (1) the termination of this Agreement or any provision thereof shall not relieve any Party from any expense, liability or other obligation or remedy therefor which has accrued or attached prior to the date of such termination, (2) as among the Parties (but not as to any successor or assign of such Party following the termination of this Agreement), the provisions of Section 6.1 and Exhibit G shall survive such termination and remain in full force and effect until the Tax Partnership is terminated in accordance with the terms of the Tax Partnership Agreement, (3) the provisions of Section 2.6 and ARTICLE XI (other than Section 11.8) shall survive such termination and remain in full force and effect indefinitely, (4) the provisions of Section 2.13 shall survive such termination and remain in full force and effect in accordance with its terms, and (5) the provisions of ARTICLE V and this clause (5) shall survive the termination of this Agreement until the 25th anniversary of the Closing Date; provided that with respect to this clause (5), from and after the termination of this Agreement, (x) Section 5.2 shall terminate and any Fill-In Interests acquired by any Party shall be deemed to be an Option Interest subject to Section 5.3, (y) either Party can terminate the provisions of ARTICLE V with respect to all or any portion of the Development Area prior to the 25th anniversary of the Closing Date by giving 6 months prior written notice of the same to the other Parties and (z) upon the sale of any Lease and/or well by any Party to a Third Party, the provisions of ARTICLE V with respect to such Lease and/or well and all related assets with respect thereto shall terminate.
