The General Manager (whose roles are defined in Section 5.1 below) shall execute and file such certificates as shall be required under the laws of each State in which the Company does business for the Company to be qualified to do business under its name in that State.

1.3                       Principal Office: The principal office of the Company shall be located in Sheridan County, Wyoming. The Company may have such other offices and business locations

2

as the Members may agree. The books and records of the Company shall be maintained at the Company’s principal office or at such other location as agreed upon by the Members.

1.4                               Perpetual Existence: The Company’s existence began upon the issuance of a Certificate of Formation by the Secretary of State of Delaware on March 28, 2007, and shall continue in perpetuity until the Company is dissolved or liquidated in accordance with this Agreement or as required by the laws of the State of Delaware.

1.5                               Agent: Corporation Service Company (CSC) shall be the Company’s agent in the States of Delaware and Wyoming for service of process and receipt of notice until otherwise determined by the Executive Committee (whose roles are defined in Section 5.3 below).

ARTICLE 2

BUSINESS PURPOSE

2.1                               Purpose: The business purpose for which the Company has been formed is to plan, establish and conduct a coal mining business in Sheridan County, Wyoming, within the area as set forth on the map attached hereto as Exhibit C and within such other areas as agreed to by the Members (the “JV Area”). Without limiting the generality of the foregoing, the following activities shall be deemed to be within the Company’s business purpose:

(a)                                 The acquisition, by purchase or lease, of coal reserves, coal and surface properties (including the Consol Leased Properties and the Chevron Leased Properties), water rights if applicable, roads, utility service, coal preparation and processing facilities, transportation and loading facilities, coal mining machinery and equipment, and other infrastructure, plant and equipment appropriate to a commercial coal mining operation;

3

(b)                                 The conduct of pre-mining exploration, testing, mapping, engineering and permitting activities necessary or appropriate to a commercial coal mining operation;

(c)                                  The financing (including bonding) of the development and operation of the coal mining operation to be conducted by the Company, including the encumbrance of the Company’s properties and assets as may be necessary or appropriate to secure financing;

(d)                                 The processing and transporting of coal and other products (such as coalbed methane) mined and produced by or for the Company;

(e)                                  Activities approved by the Executive Committee relating to distribution and marketing of coal and other products;

(f)                                   The post-mining reclamation of the properties of the Company, whether leased, owned or controlled, impacted by the Company’s operations; and

(g)                                  Such other activities as are necessary or desirable to carry out the intentions of the Members to conduct a coal mining operation upon the Consol Leased Properties, the Chevron Leased Properties and such other properties in the JV Area that the Company may acquire.

2.2                               Limitation on Purpose: The business purpose of the Company shall not be extended beyond the purpose set forth in Section 2.1 by implication or otherwise without the unanimous consent of the Members.

2.3                               JV Area Properties: All properties in the JV Area necessary or desirable for fulfillment of the Company’s business purpose shall be sought and acquired, whether by lease, purchase or otherwise, by the Company or by a Member for the benefit of the Company. If either Member notifies the Company and the other Member of the notifying Member’s desire to acquire such a property interest, the Company (acting by vote of the Executive Committee

4

representatives appointed by the non-notifying Member) shall have a period of one hundred twenty (120) days in which to determine (by notice to both Members) to acquire such interest in the Company’s name. Both Members shall provide reasonable cooperation to the Company’s efforts in pursuing such acquisition. If the Company does not give notice within such time period of its determination to pursue the acquisition, the notifying Member is free to pursue acquisition of such property for its own account and its own development. If, however, the notifying Member determines that the opportunity to acquire the property interest may be lost through delay, the Member may acquire the interest in its own name during the same one hundred twenty (120) day period, subject to the Company’s right to acquire the property interest from the Member on the same terms as the Member acquired it. To so acquire the property interest, the Company shall give notice to the notifying Member within the same one hundred twenty (120) day period and the notifying Member shall take the appropriate actions to cause the transfer of the property interest to the Company. For the avoidance of doubt, property interests related to the exploration, development, production, transportation or marketing of crude oil, natural gas (excluding coalbed methane) or other hydrocarbons are not deemed necessary or desirable for fulfillment of the Company’s business purpose.

2.4                               Other Activities: Subject to the provisions of Section 2.3, each Member and all of its current and future Affiliates may engage, or invest in, other business ventures of any nature and description, independently or with others, which other business ventures may be competitive with the business of the Company. (For purposes of this Agreement, an “Affiliate” of a given entity shall mean any individual, corporation, partnership, limited liability company or other entity that, directly or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with the given entity. For this purpose “control” means possession,

5

directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of securities or partnership or other ownership interest, by contract or otherwise).) Neither a Member nor its Affiliates, nor any shareholder, member, partner, officer, director, employee or agent of any of the foregoing, shall have any rights, by virtue of this Agreement or its interest in the Company, in and to the independent ventures of the other Member, nor shall any Member or such entities affiliated with such Member be deemed to have any fiduciary obligations to the other Member or its affiliated entities.

2.5                               Indemnity of Members by the Company: To the fullest extent permitted by law, the Company shall indemnify, defend and hold harmless each Member from and against any loss, liability, damages, expenses or claims (including attorneys’ fees) sought against or incurred by such Member (i) as a result of its status as a Member of the Company or arising out of or incidental to the business of the Company, or (ii) by reason of any acts, omissions or alleged acts or omissions arising out of or purportedly arising out of its activities as a Member on behalf of the Company or activities of the Company, but excluding in each case (i) and (ii) any loss, liability, damage, expense or claim to the extent resulting from the fraud, bad faith, gross negligence or willful misconduct of the indemnified Member.

(i)                                     charging interest to the Delinquent Member on the unpaid portion of such required payment at the sum of (A) the “prime rate” or “reference rate” of interest quoted in The Wall Street Journal published on the due date plus (B) two percent (2%) per annum (such sum being the “Default Interest Rate”) from the date that such payment was due until the date that it is made;

(ii)                                  taking such action as the other Member may deem appropriate to obtain payment by the Delinquent Member of the required payment, including (A) instituting a dispute resolution procedure pursuant to Section 11.9 or (B) withholding any distributions otherwise payable to the Delinquent Member;

(iii)                               permitting (but not requiring) the other Member (“Lending Member”) to deliver to the Company all or any portion of the Delinquent Member’s unpaid required payment, with the following results:

(A)                               the sum delivered constitutes a loan from the Lending Member to the Delinquent Member pursuant to the applicable provisions of this Agreement;

9

(B)                               the principal balance of such loan and all accrued unpaid interest thereon is due and payable in whole on the tenth (10th) business day after written demand therefor by the Lending Member to the Delinquent Member;

(C)                               the unpaid principal balance of such loan bears interest at the Default Interest Rate from the date that such loan is made until the date that the principal balance, together with all interest accrued thereon, is repaid to the Lending Member;

(D)                               all distributions from the Company that otherwise would be made to the Delinquent Member (whether before or after dissolution of the Company) instead shall be paid to the Lending Member, for credit against the unpaid interest accrued thereon and the unpaid balance of such loan, until the principal balance and all interest accrued thereon shall have been paid in full to the Lending Member (with payments being applied first to accrued and unpaid interest and then to principal), but all such payments to the Lending Member shall be treated for all other purposes of this Agreement as a distribution to the Delinquent Member, and

(E)                                the Lending Member shall have the right (in addition to the other rights and remedies granted to it pursuant to this Agreement, including but not limited to rights and remedies pursuant to Sections 5.6 and 8.1(c) herein, or available to it at law or in equity) to take, after five business days’ advance written notice to the Delinquent Member, such action (including arbitration proceedings under Section 11.9 below) as the Lending Member may deem appropriate to obtain payment by the Delinquent Member of the principal balance

10

of such loan and all interest accrued thereon, at the cost and expense of the Delinquent Member.

3.7                               No Entitlement to Return of Capital: A Member is not entitled to the return of any part of its capital or to be paid interest in respect of either its capital account or its capital contributions. An unrepaid capital contribution is not a liability of the Company or of either Member (unless otherwise agreed to by the Members). A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s capital contributions. The foregoing provisions do not limit the Members from agreeing to distribute capital of the Company or from receiving distributions of capital upon the liquidation of the Company.

ARTICLE 4

INTERESTS, ALLOCATIONS & DISTRIBUTIONS

4.1                               Interests in Company: In consideration of their contributions of such assets as are set forth in Exhibit A-1 and Exhibit A-2, the Members shall have the following membership interests in the Company (herein, “Interests”):

4.2                               Allocations:

(a)                                 Except as otherwise provided in this Agreement, the profits and losses of the Company (and each item of income, deduction, gain, loss and credit entering into the computation thereof) shall be computed in accordance with generally accepted accounting

11

principles, consistently applied, and shall be allocated to the Members in proportion to their Interests.

(b)                                 Net gains and losses from Capital Transactions shall be allocated to the Members in proportion to their Interests. (As used in this Agreement, the term “Capital Transactions” means any of the following: the sale or transfer other than in the ordinary course of business of the Company’s properties; the financing or refinancing of the Company’s properties; the condemnation by exercise of the power of eminent domain of any of the Company’s properties; the receipt of insurance proceeds from the loss or destruction of a substantial asset of the Company which proceeds are not applied to the restoration or repair of the lost or damaged asset; transactions in connection with the termination and dissolution of the Company; and any other transaction that results in extraordinary receipts or proceeds which, in accordance with generally accepted accounting principles, are attributable to capital.)

(c)                                  It is the intention of the Members that the allocations in this Agreement shall be deemed to have “substantial economic effect” within the meaning of Section 704 of the Code and Treas. Reg. § 1.704-1, et seq. (the “Regulations”). If the provisions of this Agreement should be deemed to be inconsistent with or in conflict with Section 704 of the Code or the accompanying regulations thereunder, then Section 704 of the Code and the Regulations shall be deemed to override the contrary provisions of this Agreement. If Section 704 of the Code or the Regulations at any time require that this Agreement contain provisions that are not expressly set forth herein in order for the allocations in this Agreement to have substantial economic effect, such provisions shall be incorporated into this Agreement by reference and shall be deemed a part of this Agreement to the same extent as though they had been expressly set forth herein, and the Members shall be authorized by an instrument in writing to amend the terms of this

12

Agreement to add such provisions, and any such amendment shall be retroactive to whatever extent required to create allocations having substantial economic effect. If any allocations are made pursuant to the Regulations, such allocations shall be taken into account in making subsequent allocations hereunder, as necessary to prevent the allocations pursuant to the Regulations, to the maximum extent practicable without violation of the Regulations, from distorting the manner in which Company distributions will be divided between the Members pursuant to this Agreement.

(d)                                 In order to comply with Section 704(c) of the Code, allocations for capital and tax purposes shall be made on a functional basis; that is, each deduction will be allocated to each of the Members in accordance with its respective contribution to the expenses giving rise to the deduction or in accordance with its respective adjusted basis in the assets giving rise to the deduction.

4.3                               Distributions: Except for distributions arising in connection with the liquidation of the Company which shall be handled as provided in Section 8.3, the Net Distributable Cash Flow of the Company shall be distributed periodically when and as directed by the Executive Committee, to the Members in proportion to their Interests. If any property other than cash is distributed by the Company to a Member, the fair market value of such property shall be used for the purpose of determining the amount of such distribution; and the difference, if any, of such fair market value above or below the value at which such property is carried on the books of the Company shall be credited or charged to the capital accounts of the Members in proportion to their Interests As used in this Agreement:

(i)                                     “Net Distributable Cash Flow” means any Available Funds after (A) paying the ordinary and necessary expenses of the Company, (B) paying any debts or

13

liabilities of the Company to the extent required under any agreement with any lender or creditor (including either Member) and (C) establishing reserves to meet current or reasonably expected obligations of the Company as the Executive Committee determines in its sole discretion; and

(ii)                                  “Available Funds” means Company cash on hand, as of the date of computation, including (without limitation) cash derived from any one or more of the following sources: (a) the capital contributions of the Members made pursuant to the terms of this Agreement, (b) the proceeds of any disposition of all or any portion of the assets of the Company, including, but not limited to, any insurance proceeds, (c) any distribution (including liquidating distributions) received from any entity in which the Company holds an interest, (d) all Company operating income, and (e) any other sources of cash.

4.4                               Transactions or Disputes with Related Parties:

(a)                                 The Company may contract or arrange with either Member or its Affiliates for the performance of services for the Company, and the payment of compensation therefor, in carrying out the business of the Company with such Member or Affiliate acting as an independent contractor in accordance with Section 5.7, provided that such contract or arrangement is approved by the Executive Committee representatives appointed by the disinterested Member.

(b)                                 Notwithstanding anything to the contrary contained in this Agreement, in the event of any dispute between the Company and either Member or its Affiliates (a “Related Party”), arising under any contract or arrangement between the Company and any Related Party (a “Contractual Dispute”), the Executive Committee representatives appointed by the

14

disinterested Member shall be authorized to manage and direct the conduct of such Contractual Dispute on behalf of the Company. In no event may a Related Party which is a party to such Contractual Dispute represent or make any decisions on behalf of the Company in any Contractual Dispute. The Company is specifically authorized to pursue any claim or defense with respect to a Contractual Dispute to enforce the rights of the Company.

21

restriction of the Members to bind the Company, it is expressly agreed that no Member shall have the right as a Member to exercise any control over the retention or termination of independent contractors or consultants or to direct the hiring, promotion or termination of any employees.

In the event either Member materially defaults in the performance of any material obligation under this Agreement and such defaulting Member has not cured such default within ninety (90) days of its receipt of a notice specifying such default, and the defaulting Member has not challenged the occurrence of such default pursuant to the dispute resolution procedures set forth in Section 11.9, all voting, management and control rights of the defaulting Member shall be suspended and shall not be reinstated until the default has been fully satisfied. Upon the filing by or against either Member (a “Bankrupt Member”) or any of its Affiliates of any petition in bankruptcy under any chapter of title 11, United States Code or any successor statute, all voting, management and control rights of the Bankrupt Member with respect to the Company shall immediately cease and be of no further force or effect. The value of such Bankrupt Member’s voting, management and control rights shall be determined in accordance with generally accepted accounting principles and shall be added to the Bankrupt Member’s Capital Account. Without limitation on the foregoing, during any suspension and following any termination of such voting, management and control rights, the Member affected by such suspension or termination shall not have representatives on the Executive Committee and may not participate in exercise of the right of first refusal provisions of Section 9.2 of this Agreement or the option

22

to purchase provisions of Section 9.3 of this Agreement, in each case without the written consent of the non-disabled Member.

5.7                               Secondment and Services from the Members:

(a)                                 The General Manager may take advantage, in his or her discretion, of opportunities to obtain the services of management-salaried employees of the Members and/or the Members’ Affiliates. The General Manager will give the opportunity to qualified and experienced management-salaried individuals nominated by each of the Members to fill any such open positions within the Company. Such employees will be seconded from the Members and the Company will reimburse the Members for their seconded employees. It will be the General Manager’s intent to balance the number of seconded employees from each of the Members, so long as both Members nominate a balanced number of individuals to provide the services to the Company pursuant to this Section 5.7. Non-management, hourly employees of the Company shall not be seconded from the Members, but rather, shall be hired directly by the Company based on experience and qualifications as determined by the General Manager or his or her duly delegated personnel.

(b)                                 In the event that loaned employees are to be furnished by a Member or its Affiliates to the Company, the Company and the applicable Member or Affiliate shall enter into a Loaned Employee Agreement substantially in the form of Exhibit D attached hereto, pursuant to which the Member or its Affiliate shall make available the services of such employees as the Company and the Member or Affiliate may agree.

(c)                                  Within ten (10) days of the execution of this Agreement, (i) the Company and Consol shall enter into a Services Agreement substantially in the form of Exhibit E attached hereto, pursuant to which Consol or an Affiliate shall furnish independent contractor services to

26

which the Tax Matters Partner reasonably believed to be in the best interest of the Company or the Members. The Tax Matters Partner shall not be indemnified under this provision against any liability to the Company or its Members to which the Tax Matters Partner would otherwise be subject by reason of gross negligence or willful misconduct.

(b)                                 entry of a decree of judicial dissolution of the Company, pursuant to Section 11.9(d) below or otherwise;

(d)                                 in the event that the results of the preliminary work program, which includes preliminary testing, engineering and evaluation of the cost of the operation and related mining activities in the JV Area, are not favorable and do not yield projected commercially reasonable financial operating figures.

The Company may only be dissolved upon the happening of one of the foregoing events. The Members hereby expressly waive dissolution of the Company on account of any other event (such as the bankruptcy of a Member) to the extent such event may be superseded by the terms of this Agreement. Dissolution of the Company shall be effective upon the date on which the

28

event giving rise to the dissolution occurs, but the Company shall not terminate until the assets of the Company have been distributed as provided in Section 8.3. Prior to the liquidation and termination of the Company, the business of the Company, and the rights and obligations of the Members relative to the Company, shall continue to be governed by this Agreement.

8.2                               Liquidation and Winding Up Upon Dissolution: If the Company is dissolved, the Company shall be wound up and liquidated in accordance with the requirements of law and the following provisions:

(b)                                 Upon dissolution, the Liquidator shall ensure that an account is taken as soon as practicable of all property, assets and liabilities of the Company;

(c)                                  Each Member shall pay to the Company any amount owed by it to the Company, and the Liquidator shall be empowered and authorized to pursue any claims of the Company against such Member, including claims in any bankruptcy or other court proceeding in lieu of any dispute resolution procedures otherwise required by Section 11.9; and

(d)                                 The assets and property of the Company or the proceeds of any sale thereof, together with payment received pursuant to Section 8.2(c), shall be applied by the Liquidator as provided in Section 8.3.

8.3                               Distributions Upon Liquidation: Upon the dissolution of the Company, the assets of the Company shall be sold (or distributed in kind, at the election of the Members) in an orderly fashion, and the proceeds thereof shall be distributed, on or before the later to occur of

29

(i)         the close of the Company’s taxable year, or (ii) ninety (90) days following the date of such dissolution, as follows:

(a)                 First:                                     To the payment and discharge of all of the Company’s debts and liabilities, to the necessary expenses of liquidation, to a cash reserve for the completion of the reclamation obligations of the Company and to the establishment of a cash reserve which the Members determine to create for unmatured and/or contingent liabilities and obligations of the Company;

(c)                  Third:                               To the Members in accordance with their Capital Accounts; provided, however, that if such distribution would vary in any material respect from that provided for under Section 4.3 (if it were applicable to such distribution), then items (including gross items) of income, gain, loss and deduction for the year of liquidation (and any prior year as to which an amended return may be filed) shall be allocated in such a manner as to cause, to the maximum extent practicable without violation of the Regulations, the distributions to the Members pursuant to this Section 8.3(c) to equal what they would have been had such distributions been made pursuant to Section 4.3; and provided further, that if the Liquidator establishes any reserves in accordance with the provision of Section 8.3(a), then the distributions pursuant to this Section 8.3(c) (including distributions of such reserves) shall be pro rata in accordance with the balances of the Member’s Capital Accounts.

30

No Member shall be required to contribute any property to the Company or any third party by reason of having a negative Capital Account.

ARTICLE 9

RESTRICTIONS ON TRANSFERS BY MEMBERS

9.1                               Permitted Transfers: Neither Member may sell, assign, transfer, pledge, encumber, create a security interest in or otherwise dispose of all of any part of its Interest in the Company without the express written consent of the other Member, except as provided in this Article; provided that a Member may assign all but not part of its Interest to an Affiliate. Any attempted sale, assignment, transfer, encumbrance or disposition not expressly permitted by this Article shall be null and void ab initio and of no force and effect. Any assignment, including any assignment to an Affiliate of a Member, shall not operate to release the assigning Member of its obligations and liabilities under this Agreement without the consent of the other Member.

9.2                               Right of First Refusal: Either Member may transfer all (but not part) of its Interest to another person (other than an Affiliate) after complying with the following provisions of this Section:

(a)                                 Offer to Sell. Either Member desiring to transfer all (but not part) of its Interest (the “Transferring Member”) shall first deliver a written notice to the other Member advising it of the proposed price and other terms of a bona fide binding offer (the “Offer”) from a third party that is Creditworthy as defined below.

(b)                                 Exercise. The other Member shall have the right to acquire the Transferring Member’s Interest at the price and on the terms of the Offer if, within forty-five (45) days after receipt of the Offer, it notifies the Transferring Member of exercise of such

31

option. If the other Member exercises such right, the transaction shall be consummated within ninety (90) days after receipt of the Offer, or at such other date as the Members may agree.

(c)                                  Completion of Sale. If the other Member does not exercise such right within the 45-day period described in clause (b), the Transferring Member may, at any time within one hundred twenty (120) days after the expiration of such forty-five (45)-day period, but no later, transfer its Interest to a Creditworthy third party, on terms no more favorable to the third party than those offered to the other Member. Upon transfer, the indemnity and other obligations of the Transferring Member under the Agreement shall be terminated as to future activities, but the indemnity and other obligations of the Transferring Member shall survive and continue to apply with respect to actions or omissions occurring prior to transfer. As used in this Agreement, “Creditworthy” means a person with the financial and technical capability to perform its obligations under this Agreement and with a tangible net worth, based on audited financial statements provided to the remaining member, which equals or exceeds a tangible net worth reasonably satisfactory to the remaining member.

9.3                               Option to Purchase: Each Member (the “Affected Member”) grants to each other Member an option to purchase the Affected Member’s Interest, which option shall be exercisable either (i) in the event that the Interest of the Affected Member is involuntarily transferred to a pledgee, judgment creditor, assignee for the benefit of creditors, receiver, trustee in bankruptcy or other person, or (ii) upon the filing by or against the Affected Member or any of its Affiliates of any petition in bankruptcy under any chapter of title 11, United States Code or any successor statute. Upon the occurrence of any event described in clause (i) or (ii) above (an “Option Triggering Event”), the other Member shall have the option and privilege of purchasing the Affected Member’s Interest by giving notice to the Affected Member of exercise

32

of such option not later than ninety (90) days following such transfer, for the fair market value of such Interest as determined by an independent appraiser chosen by the Company. No pledgee, judgment creditor, assignee for the benefit of creditors, receiver, trustee in bankruptcy or other holder of a claim to the Interest of a Member may sell, foreclose upon, hold or otherwise transfer such Interest in derogation of the option hereby granted.

9.4                               Substitute Members. No transferee of any Interest (including transferees by operation of law) shall be admitted as a Member hereunder or acquire any rights hereunder, including voting rights, representation on the Executive Committee or the right to receive distributions and allocations in respect of a transfer, unless such Interest is transferred in compliance with Article 9. Each permitted transferee of an Interest under Article 9 shall execute an instrument assuming and agreeing to perform all obligations of a Member under this Agreement and shall thereupon be admitted as a Member of the Company in the place of the Member whose Interest was transferred to such transferee; provided that the transferor shall remain liable for performance of all obligations under this Agreement arising prior to the date of such assumption and agreement.

4.3                               to use the Surface Lands as may be reasonably required or convenient in connection with its Mining Operations.

76

5.                                      Term. This Lease shall be for an initial term often (10) years from the Effective Date and as long thereafter as Lessee is conducting Mining Operations, (“Term”), unless this Lease is sooner terminated under Section 14.

6.                                      Cross-Mining and Commingling.

6.1                               Cross Mining Within the JV Area. Lessee shall have the right to conduct Mining Operations on the Surface Lands in conjunction with, or in support of, mining activities conducted by Lessee anywhere within the JV Area.

6.2                               Commingling Within or Outside the JV Area. Lessee shall have the right to commingle Lessor’s Coal with other coal produced from both within and outside the JV Area. Lessee shall keep a strict account of the quality and tonnage of both Lessor’s Coal and other coal produced or purchased by Lessee and all those tonnages shall be determined before any coal may be commingled with Lessor’s Coal. The “Gross Sales Price,” as defined below, for Lessor’s Coal shall include an adjustment upward or downward to reflect the amount by which the arm’s length market price for Lessor’s Coal is greater than or less than the arm’s length market price of the commingled coal.

7.                                      Production Royalties.

7.1                               Royalty. Lessee shall pay Lessor a production royalty equal to the product of 8% of the “Gross Sales Price,” multiplied by the tonnage of the Lessor’s Coal sold by Lessee in an arm’s length transaction during each month. The “Gross Sales Price” will be calculated on a per-ton basis using the gross amount paid to Lessee F.O.B. at the “mine” for all Lessor’s Coal produced from the mine that is sold during the month. The term “mine” as used in this Section 7.1 shall include all conveyors, rail and truck loadouts and other facilities associated with the mining and loading of Lessor’s Coal. Lessee shall disclose to Lessor the price and any adjustments to the price by way of an itemized statement in such form and detail as Lessee may reasonably adopt. The production royalty for all of Lessor’s Coal sold during any calendar month shall be paid on or before the 30th day of the next calendar month.

7.2                               Weights & Market Price. All quantities used in the calculation of production royalties shall be obtained by weighing by certified weighing systems or by other measurements using prudent engineering methods. When Lessor’s Coal is commingled with other coal or is sold from coal stockpiles, Lessee shall determine Lessor’s proportionate amount of coal sold using reasonable and practical allocations. All relevant data that may be used for the purpose of ascertaining the arm’s length market price or weights of Lessor’s Coal on which royalty is due shall be available in detail at all reasonable times for Lessor’s inspection.

7.3                               Recoverable Materials. Lessee may remove, sell, or otherwise dispose of, Recoverable Materials. If Lessee sells any Recoverable Materials, Lessee shall compensate Lessor at a rate of 8% of the total Gross Sales Price realized by the Lessee.

7.4                               Dealings with Affiliates. Lessee shall conduct any dealings with Affiliates on fair and customary arm’s length terms.

77

7.5                               Survival. The obligation to pay accrued production royalties shall survive the termination of this Lease.

7.6                               Payments. Lessee shall make all payments to Lessor by check or wire transfer.

8.                                      Royalty Adjustments.

8.1                               Proportional Interest. Lessee shall pay the production royalties to Lessor only in the proportion that Lessor’s interest bears to the undivided fee. Lessor shall timely repay any overpayment and Lessee shall timely pay Lessor for any underpayment that may occur.

8.2                               Interest Adjustments. If Lessor’s interest is increased or decreased by any reversion or otherwise, the royalties shall be adjusted accordingly at the first payment date after Lessee has been notified of the change.

8.3                               Binding Nature of Statements. If Lessor or Lessee does not question in writing to the other the accuracy of any monthly statement of royalty or any other payments to be made hereunder within three (3) years after receiving it, the statement or payment shall be conclusive.

9.                                      Lessee Operations.

9.1                               Operating Standards. Lessee shall conduct Mining Operations in a workmanlike manner and in such a manner as to recover the Maximum Economically Recoverable (“MER”) quantity of Lessor’s Coal. Lessee shall employ machinery and methods that are modern and efficient and shall conduct the Mining Operations according to a proper overall mine plan and system of mining.

9.2.                            Required Permits. Lessee shall timely obtain all Permits required for the Mining Operations. Lessee shall maintain all Permits in full effect, timely file all renewal applications and remain in compliance with all Permits. Lessee shall, upon Lessor’s written request, make available copies of the Permits for Lessor’s review and copying.

9.3                               Compliance with Laws and Regulations; Indemnification. Lessee shall conduct all Mining Operations in accordance with all Applicable Laws. Lessee shall indemnify and hold harmless Lessor from and against all claims asserted against Lessor arising from failure by Lessee to comply with Applicable Laws, including Lessee’s failure to keep any required bonds in place. Lessee may appeal from any ruling, regulation, order or other determination, and carry on its operations in accordance with its interpretation of them pending final determination, in which event Lessee shall indemnify Lessor from any loss, liability or expense resulting from an adverse determination.

9.4                               Maps and Annual Reports.

At least thirty (30) days prior to beginning to remove overburden for the extraction of Lessor’s Coal and annually thereafter, Lessee shall provide to Lessor a map

78

detailing Lessee’s mining plan and proposed activities within the JV Area. Thereafter, Lessee shall provide to Lessor a copy of the annual report as required by Wyoming statute ▇▇-▇▇-▇▇▇. Lessor may in good faith object to the mining plan and proposed activities relating to the Leased Interests. Lessor’s objection will not result in a delay in Lessee’s Mining Operations or Mine Permits. If Lessor and Lessee are unable to reach a mutually satisfactory resolution of Lessor’s objections, either party may resort to the dispute resolution provisions of Section 20.

9.5                               Records and Audit Rights. Lessee shall keep a correct record for three (3) years after Lessor’s Coal or other materials have been removed relating to the mining, shipping and selling of Lessor’s Coal and shall permit Lessor or Lessor’s agents at reasonable times to examine all relevant records, including all: books of account, records of analyses, weight slips, sales contracts, shipping records, mining plans, projections, prints, surveys, maps and relevant documents, records and instruments, during the three-year audit period. Lessee will not be required to retain, and Lessor will have no further right to review, the production and payment records after the three (3) year retention period.

9.7                               Reclamation of Surface Lands. Lessee shall perform all Reclamation activities on the Surface Lands required in connection with Lessee’s Mining Operations, at its sole cost, as required by Applicable Laws.

9.8                               Regulatory Notices. Lessee will provide to Lessor prompt oral notice, followed by written notice, of all notices, demands, citations or complaints (“Regulatory Notices”) issued by any government agency to Lessee with respect to (i) the release of Hazardous Substances on the Surface Lands, or (ii) which causes an interruption in the Mining Operations of Lessee Parties for a period of more than seven (7) business days. Lessee shall undertake promptly those actions required by Applicable Laws necessary to cure or comply with the Regulatory Notices.

9.9                               Waste Disposal. Lessee shall comply with all Applicable Laws governing the disposal of refuse or waste materials that Lessee disposes of on the Surface Lands. If Lessee is disposing of its refuse or waste materials in violation of any Applicable Law and in such manner as to create an environmental hazard on the Surface Lands, Lessor may by written notice to the Lessee require Lessee to cease doing so and to ▇▇▇▇▇ the condition.

9.10                        Lessor Release. Lessor Parties shall not be liable to Lessee, and Lessee hereby releases them from any Claim, except to the extent of Lessor’s indemnity provided for in section 9.11,b.

9.11                        Indemnity.

a.                                      Lessee does hereby agree to indemnify, defend and save harmless Lessor and each Lessor Party from and against all Claims (i) asserted against a Lessor Party as a result of Lessee’s breach of any representation, warranty, or covenant hereof; or (ii) arising out of the occupancy, use, operations, actions or omissions of any Lessee

79

Party, in all cases, whether or not Lessee may have acted negligently; or (iii) arising from environmental conditions created by Lessee or violations of Applicable Laws first occurring or exacerbated during the Term; or (iv) reclamation activities of Lessee on the Surface Lands; or (v) environmental conditions or reclamation obligations assumed by Lessee either contractually or by operation of law; provided that Lessee shall not be responsible for any Claims resulting from the negligence of Lessor acting as Lessor and not on behalf of Lessee. If any action or proceeding is brought against any Lessor Party by reason of any Claim, Lessee, upon notice from any the Lessor Party, shall defend the Claim at Lessee’s expense with counsel reasonably acceptable to Lessee and the Lessor Party and, if any judgments shall be rendered therein against Lessor, Lessee shall satisfy them and all the costs and expenses thereof, including reasonable attorneys’ fees.

▇.                                      ▇▇▇▇▇▇ does hereby agree to indemnify, defend and save harmless Lessee and each Lessee Party from and against all Claims (i) arising out of the occupancy, use, operations, actions or omissions of any Lessor Party, in all cases, whether or not Lessor may have acted negligently; or (ii) arising from environmental conditions created by Lessor or violations of Applicable Laws existing as of the Effective Date or exacerbated during the Term provided that Lessor shall not be responsible for any Claims resulting from the negligence of Lessee. If any action or proceeding is brought against any Lessee Party by reason of any Claim described in this Section 9.11(b), Lessor, upon notice from any the Lessee Part, shall defend the claim at Lessor’s expense with counsel reasonably acceptable to Lessor and the Lessee Party and, if any judgments shall be rendered therein against Lessee, Lessor shall satisfy them and all the costs and expenses thereof, including reasonable attorneys’ fees.

9.12                        Insurance. Prior to Lessee employing any person as an employee, whether directly or through a loaned employee arrangement, and during the Term thereafter, Lessee shall maintain the insurance as set forth on Exhibit C.

9.13                        Damaged, Lost, Impaired or Bypassed Coal.

a.                                      If any of the economically recoverable Lessor’s Coal, within the meaning of MER, is lost or bypassed as a proximate result of Lessee’s failure to operate as a prudent mine operator (“Lost Coal”), Lessee shall pay production royalty for the Lost Coal as if mined and removed, at the times Lessee would otherwise have mined the Lessor’s Coal in its normal Mining Operations.

b.                                      If Lessee encounters any substantial seam of the Lessor’s Coal that Lessee considers economically un-recoverable for any reason, Lessee shall notify Lessor of that fact as promptly as circumstances reasonably permit. Upon receipt of the notice, Lessor shall have the right to appoint a representative to inspect mat portion of Lessor’s Coal that Lessee considers to be economically un-recoverable and Lessor’s representative shall be given reasonable access to the mine workings and all pertinent information available to Lessee regarding the Lessor’s Coal. However, Lessee shall not be obligated to delay its Mining Operations in order to afford such access to Lessor’s representative and Lessor’s representative shall not be permitted to unreasonably interfere with Lessee’s Mining Operations. At Lessor’s request, Lessee’s representative shall meet and confer with Lessor’s representative and the

80

representatives shall endeavor in good faith to agree whether the Lessor’s Coal at issue is economically recoverable. If the representatives are unable to agree on that issue, they shall select a disinterested and independent person experienced in geology and coal mining economics to act as an arbitrator, whose decision shall be binding upon Lessor and Lessee. The prevailing party shall be entitled to reimbursement by the other party for a portion or all of the arbitration costs, as determined by the arbitrator to be appropriate. If the representatives selected by Lessor and Lessee cannot agree on an arbitrator, either party may invoke the dispute resolution provisions of Section 20 of this Lease to resolve the dispute. Even if it is determined, pursuant to the procedures set forth in this Section 9.13, that the Lessor’s Coal in dispute is economically recoverable, Lessee may elect not to mine it and, if Lessee so elects, the Lessor’s Coal shall be deemed to be Lost Coal.

c.                                       Any payment to be made by Lessee for a royalty paid on Lost Coal shall be based on the Gross Sales Price, as used in Section 7.1, for a one (1) year period (or the period of time the Mining Operations have produced coal if less than one (1) year), as adjusted by the arbitrator for such factors as he or she may determine to be appropriate including the Btu, sulfur, sodium, and ash content of the Lost Coal. If Lessee subsequently mines any of the Lost Coal for which payment has been made under this section, Lessee shall not be liable for any additional production royalty thereon.

▇.                                      ▇▇▇▇▇▇ shall have a maximum of three (3) years after any Lessor’s Coal becomes Lost Coal in which to bring a claim against Lessee for payment of production royalty on it. The three (3) year period shall begin on the date that Lessor knew or reasonably should have known, based on credible evidence, that Lessee no longer intended to attempt to mine the Lost Coal in question. The procedure in this Section 9.13 shall be Lessor’s sole means of challenging Lessee’s determination that any Lessor’s Coal is not economically recoverable.

e.                                       Lessee shall use reasonable methods to test the extent of Lessor’s Coal.

10.                               Title and Lessor’s Interests.

10.1                        Disclaimer-Condition of Leased Interests. Lessor does not warrant its title to the Leased Interests, or the quantity or quality of the Coal, or the condition of the Leased Interests. Lessee shall inspect the Surface Lands and ascertain what mining rights and privileges Lessor owns within the JV Area before conducting any Mining Operations thereon. Lessor makes no representation that any reserve calculations or estimates, exploratory data, analyses or samples it may furnish to Lessee are accurate or complete. All warranties, other than those set forth in this Lease, are hereby disclaimed, including, without limitation, warranties of merchantability and fitness for a particular purpose. Lessee accepts the Surface Lands and the Lessor’s Coal “As Is, Where Is.”

10.2                        Title Dispute. Upon receipt of notice of title dispute or claims adverse to Lessor’s interest, Lessee may withhold any further payments to Lessor until sixty (60) days after receipt of evidence satisfactory to Lessee that the dispute and adverse claim have been resolved.

81

10.3                        Lessee’s Option to Cure or Terminate. Lessee shall have the right at any time during the Term to examine the title to the Leased Interests and to cure any objections to title. If any objections have a material adverse effect on the Lessee’s Mining Operations, Lessee may terminate this Lease or that portion having a title defect on notice to Lessor.

10.4                        No Liens. Neither Lessee nor Lessor shall through its actions permit a lien or other encumbrance to be imposed on the Leased Interests.

10.5                        Rights of Third Parties. Lessee shall so conduct its operations pursuant to this Lease so as not to violate any rights of third parties.

10.6                        Surface Rights. Lessor does not own or control all of the surface overlying the Coal. Lessee will, at Lessee’s cost, acquire all surface rights, rights-of-way or other rights necessary for Lessee’s Mining Operations.

11.                               Transfers by Lessor. Lessor may transfer, as defined in Section 12 below its rights hereunder and the provisions hereof shall extend to the Lessor’s heirs, executors, administrators, successors and assigns.

11.1                        Death of Royalty Holder. In case of death of any person entitled to receive royalties or other payments, the evidence of change in ownership shall consist of letters of administration or final decree of distribution of the estate of the decedent issued by a court of competent jurisdiction. Until then, Lessee may continue to make payments in accordance with the records in Lessee’s possession as if the change or transfer had not been made, or at Lessee’s option may suspend payment until 60 days after such evidence is received.

11.2                        No Impact on Lessee. No change or division in the ownership of the Lessor’s Coal, royalties or other payments shall operate to increase the obligations or diminish the rights of Lessee.

11.3                        Divided Royalties. If ownership of royalties or other payments becomes divided, or in the event of assignment of this Lease as to a segregated portion or portions of the Leased Interests, all royalties payable hereunder shall be apportioned among the several owners by written agreement delivered to Lessee with the other documentation referenced above. In the absence of such written division agreement, payments to the original Lessor will satisfy all obligations of Lessee.

12.                               Transfers by Lessee. Lessee shall not transfer, convey, encumber, pledge or assign this Lease or its rights hereunder or sublet the Lessor’s Coal in whole or in part (collectively “transfer”) without Lessor’s prior written consent, which Lessor may not unreasonably withhold, except to (i) an Affiliate of Lessee or (ii) in connection with any merger, consolidation or sale or transfer of all or substantially all of Lessee’s stock or assets. Any attempted transfer without Lessor’s required consent shall be void.

13.                               Taxes and Liens. Lessee shall reimburse Lessor for all taxes and assessments (exclusive of income, franchise, capital stock, excess profits, or similar taxes of Lessor, or taxes paid on royalties or like taxes) that may be hereafter levied or assessed, whether against Lessor or Lessee, on account of ownership or control of the Leased Interests or Lessee’s improvements

82

thereon.
