SECTION 4.1. Due Organization; Good Standing; Power. Peabody is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority under applicable Law and its Charter Documents to own or lease and to operate its assets and to conduct or cause to be conducted the Peabody Business as it is now being conducted by Peabody. Each Subsidiary of Peabody that is being contributed or transferred to the JV Entities as a part of the Peabody Business (each, a “Peabody Transferred Subsidiary”) and each of the other Affiliates of Peabody that is transferring or contributing assets or Liabilities to the JV Entities pursuant to this Agreement (collectively, the “Peabody Transferring Affiliates” and, together with the Peabody Transferred Subsidiaries, the “Peabody Entities”) is, or will be at the Closing Date, a corporation, limited liability company or other entity duly organized and validly existing under the laws of its jurisdiction of organization.

being or to be conducted by it at the time of the Closing. Each of Peabody and each Peabody Entity is, or will be at the Closing Date, duly authorized, qualified or licensed to do business as a foreign corporation or other organization in good standing in each of the jurisdictions in which its right, title or interest in or to any of the Peabody Contributed Assets held by it or the Peabody Business conducted by it requires such authorization, qualification or licensing, except where the failure to have such authorization, qualification or licensing has not had and would not reasonably be expected to have, individually or in the aggregate, a Peabody Material Adverse Effect. Peabody has all requisite corporate power and authority under applicable Law and its Charter Documents to enter into this Agreement and the other Transaction Documents to which it is or will be a party and to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. Each Peabody Entity has, or will have at the Closing Date, all corporate or other requisite power and authority under applicable Law and its Charter Documents to enter into the Transaction Documents to which it is or will be a party, to perform its obligations thereunder and to consummate the transactions contemplated thereby.

This Agreement has been duly executed and delivered by Peabody, and at the Closing each of the other Transaction Documents to which Peabody or any Peabody Entity is a party will have been duly executed and delivered by Peabody and such Peabody Entity, as the case may be.

At the Closing, each other Transaction Document to which Peabody or any Peabody Entity is a party will be the legal, valid and binding obligation of Peabody and such Peabody Entity, as the case may be, in each case enforceable against Peabody and such Peabody Entity in accordance with its terms, except as that enforceability may be (i) limited by any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and (ii) subject to general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law).

SECTION 4.3. Absence of Conflicts. Neither the execution and delivery by Peabody of this Agreement nor the execution and delivery by Peabody or any Peabody Entity of any other Transaction Document to which Peabody or any such Peabody Entity is or will be a party, nor the consummation by them of the transactions contemplated hereby and thereby, does or will (a) conflict with, or result in the breach of any provision of, the Charter Documents of Peabody or any such Peabody Entity, (b) violate any applicable Law or any Permit or Order of any Governmental Authority applicable to or binding upon Peabody or any such Peabody Entity or to

As of the Closing Date, none of the JV Entities will be, or will be required to become, a “restricted subsidiary” or will otherwise be subject to restrictions on payment of cash distributions under any debt documents or in connection with any indebtedness of Peabody or its Affiliates.

SECTION 4.4. No Consents. Neither the execution and delivery by Peabody of this Agreement nor the execution and delivery by Peabody or any Peabody Entity of any other Transaction Document to which Peabody or any such Peabody Entity is or will be a party, nor the consummation by Peabody or any such Peabody Entity of the transactions contemplated by the Transaction Documents in accordance with the terms thereof will require any Consent of, or any registration, declaration, notice of filing made to or with, any Governmental Authority (a “Governmental Approval”), other than compliance with and filings required under the HSR Act or any applicable non-U.S. Antitrust Laws. At the Closing, no Governmental Approval or other Consent will be required by Peabody or any Peabody Entity for the consummation of the transactions contemplated by this Agreement and the other Transaction Documents to which Peabody or any such Peabody Entity is a party, except for such Governmental Approvals or Consents as have not had and would not reasonably be expected to have, individually or in the aggregate, a Peabody Material Adverse Effect.

(b) In furtherance and not in limitation of Section 6.4(a), each Party shall, and shall cause its Affiliates to, cooperate in good faith to obtain all Consents required by the terms

63

of any Contracts with Third Parties or Permits in connection with the transactions contemplated by this Agreement; provided, however, that, subject to Section 6.4(d), neither Party shall be obligated to pay any material amount as consideration therefor to, or make any material financial accommodation in favor of, the Person or Governmental Authority from whom such Consent is sought, other than filing and processing fees.

(c) In furtherance and not in limitation of Section 6.4(a) but subject to Section 6.4(e), each Party shall (i) if required by the HSR Act, submit no later than ten Business Days after the date hereof a Notification and Report Form pursuant to the HSR Act (an “HSR Filing”) with respect to the transactions contemplated by this Agreement, (ii) submit as promptly as reasonably practicable after the date hereof (A) any appropriate filings required pursuant to other Antitrust Laws in connection with the transactions contemplated by this Agreement and (B) any other necessary filings with other Governmental Authorities in connection with the transactions contemplated by this Agreement, (iii) supply, and assist and cooperate with the other Party in supplying, as promptly as practicable any additional information and documentary material that may be formally requested pursuant to such Laws or by such Governmental Authorities (including any “second request”, civil investigative demand, subpoena or other similar request pursuant to compulsory process) and (iv) use its best efforts to take, or cause to be taken, all actions, and do, or cause to be done, and assist and cooperate with the other Party in doing, all things necessary, proper or advisable to cause the expiration or termination of any applicable waiting periods and the receipt of any applicable Governmental Approvals as may be necessary or advisable in order to consummate and make effective the transactions contemplated by this Agreement as soon as reasonably possible.

(d) For purposes of this Section 6.4, the “best efforts” of each Party shall include, subject to Section 6.4(e), taking all actions and doing all things necessary, proper or advisable to resolve as soon as reasonably possible and in any event prior to the Outside Date such objections, if any, as may be asserted by any Governmental Authority or any other Person pursuant to the HSR Act (regardless of whether such Party is required to submit an HSR Filing) or any other applicable Laws with respect to this Agreement or the transactions contemplated hereby, including by (i) defending any lawsuits or other Proceedings instituted, or threatened to be instituted, by any Person, whether judicial or administrative, challenging this Agreement or the transactions contemplated hereby, (ii) attempting to have repealed, rescinded or made inapplicable any Law, and to prevent the entry of, or to have vacated, lifted, reversed or overturned, any Order (whether temporary, preliminary or permanent) or other legal restraint or prohibition that is enacted, issued, promulgated, enforced or entered by a Governmental Authority that would restrain, enjoin, make illegal or otherwise prohibit or delay the consummation of the transactions contemplated by this Agreement or (iii) proposing, negotiating, committing to and effecting by consent decree, hold separate order or otherwise, (A) (1) any requirement to divest, hold separate or otherwise dispose of any Peabody Contributed Assets or any Arch Contributed Assets, (2) any requirement to conduct the business of the Peabody Business or the Arch Business in a specified manner, (3) any requirement to terminate any existing relationship, contractual rights or obligations, (4) any requirement to create any relationship, contractual rights or obligations or (5) any other limitation on its ability to, or the manner in which it does, operate, conduct or exercise decision-making over the Peabody Business or the Arch Business (any such action or limitation described in clauses (1) through (5), a “Restriction”) or (B) any requirement to modify the terms of this Agreement or the

64

other Transaction Documents in order to modify the activities or business to be conducted by the JV Entities or the scope of the Contributed Assets (any such action or limitation described in this clause (B), a “Transaction Modification”), in each case as may be necessary to cause the conditions set forth in Sections 7.1(a), 7.1(b) and 7.1(c) to be satisfied prior to the Outside Date; provided, however, that neither Party shall be required to agree to, accept or undertake any Restrictions that are not conditioned on the Closing.

(e) Nothing in this Section 6.4 shall require Peabody or Arch or any of their respective Affiliates to agree to, accept or undertake (i) any Restriction relating to any Excluded Assets or any assets, categories of assets, Subsidiaries or Affiliates not relating to the Peabody Business or the Arch Business or (ii) any Restrictions or Transaction Modifications if such Restrictions and Transaction Modifications, individually or in the aggregate, would reasonably be expected to materially reduce the synergies and other economic benefits expected to be realized through the formation of, and the transfer of the Peabody Business and the Arch Business to, the JV Company. In the event that Peabody, Arch or any of their respective Affiliates is required to divest or otherwise dispose of (or hold separate and commit or agree to divest or otherwise dispose of) any Peabody Contributed Assets or any Arch Contributed Assets, (x) all net after-Tax proceeds from such divestiture or disposal shall be contributed to the JV Company at the Closing (or, if later, promptly upon receipt of such proceeds) for no additional consideration and (y) the Parties shall cause the JV Company, effective as of the Closing, to assume any Liabilities, including any indemnification obligations, in connection with such divestiture or disposal.

(f) The Parties shall jointly direct and control all aspects of the Parties’ efforts to obtain any Governmental Approvals with respect to the transactions contemplated by this Agreement (including the termination or expiration of the waiting period under the HSR Act), including in any Proceeding initiated by any Governmental Authority, and shall jointly develop the Parties’ strategy or appropriate course of action with respect to obtaining such Governmental Approvals. Each Party shall (i) promptly notify the other Party or its counsel of any substantive communication, inquiry or investigation received by such Party from, or given by it to, any Governmental Authority and, to the extent reasonably practicable and permitted by applicable Law, permit the other Party to review in advance any proposed substantive communication to any such Governmental Authority and consider the other Party’s reasonable comments, (ii) not agree to participate in any substantive meeting or discussion with any such Governmental Authority in respect of any filing, investigation or inquiry concerning this Agreement or the transactions contemplated hereby unless, to the extent reasonably practicable and permitted by such Governmental Authority, such Party gives the other Party the opportunity to attend and participate therein and (iii) promptly furnish the other Party with copies of all correspondence, filings and written communications between them and their respective Affiliates, and Representatives, on the one hand, and any such Governmental Authority or its staff, on the other hand, with respect to this Agreement and the transactions contemplated hereby in order for such other Party to meaningfully consult and participate in accordance with this Section 6.4(f); provided, however, that any materials furnished pursuant to this Section 6.4(f) may be redacted or restricted to external legal counsel to the extent necessary to comply with applicable Laws relating to the exchange of information and to address reasonable attorney-client privilege or other relevant legal privilege or confidentiality concerns. Notwithstanding the foregoing, in the event of any dispute between the Parties relating to the strategy or appropriate course of action or

65

the content of any submission made in connection with the Parties’ efforts to obtain any Governmental Approvals with respect to the transactions contemplated by this Agreement (including the termination or expiration of the waiting period under the HSR Act), where such dispute cannot be resolved through a good faith effort involving the Parties’ respective internal counsel, Peabody shall have the right, in its sole discretion, to make the final determination with respect to such matter; provided, however, that each Party shall not, and shall cause its Affiliates not to, propose any Restriction or any Transaction Modification to any Governmental Authority or commit to or effect any Restriction or any Transaction Modification, in each case without the prior written consent of the other Party.

(g) Unless otherwise recommended by outside counsel to each of Arch and Peabody after consultation with the SEC, Arch shall, as soon as reasonably possible, but in no event later than 60 days after the date hereof, file with the SEC an application for an order to be issued by the SEC either (i) pursuant to Section 3(b)(2) of the 1940 Act declaring that Arch is primarily engaged in a business other than that of investing, reinvesting, owning, holding, or trading in securities, or, alternatively, (ii) pursuant to Section 6(c) of the 1940 Act granting Arch an exemption from all provisions of the 1940 Act (any such order, an “ICA Order”). Arch shall use, and shall cause its Affiliates to use, its best efforts to take, or cause to be taken, all actions, and do, or cause to be done, all things necessary, proper or advisable to obtain an (x) ICA Order as soon as reasonably possible and in any event prior to the Outside Date and (y) opinion of counsel described in Section 7.3(e), including delivering representation letters dated as of the Closing Date and signed by an officer of Arch, in customary form and substance, to such counsel containing representations of Arch as may be necessary or appropriate to enable such counsel to render an opinion described in Section 7.3(e) on the Closing Date; provided, however, that nothing in this Section 6.4(g) shall require Arch to purchase or divest any assets. Arch shall keep Peabody fully informed on a timely basis of the status of its application for the ICA Order and shall supply as promptly as practicable any additional information and documentary material that may be requested by the SEC in connection with the application for the ICA Order.

SECTION 6.5. Public Announcements. The Parties shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements with respect to the transactions contemplated by or the terms of this Agreement, and shall not issue any such press release or make any such public statement prior to such consultation, except to the extent such Party reasonably concludes is required by applicable Law, court process or by obligations pursuant to any rules, regulations or requirements of, or listing agreement with, any national securities exchange or national securities quotation system. The Parties agree that all formal employee communication programs or announcements with respect to the transactions contemplated by this Agreement or the other Transaction Documents shall be in forms mutually agreed between the Parties (such agreement not to be unreasonably withheld, conditioned or delayed). The Parties agree that each Party’s initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the Parties. The restrictions set forth in this Section 6.5 shall not apply to any press release or other public statement in connection with any dispute regarding this Agreement or the other Transaction Documents or the transactions contemplated hereby or thereby.

66

SECTION 6.6. Cooperation. Prior to the Closing, subject to applicable Laws, the Parties agree to cooperate in good faith to take such steps as may be reasonably necessary or advisable so that the JV Company shall be in a position to seamlessly begin operating the Peabody Business and the Arch Business immediately after the Closing. In furtherance of the foregoing, Peabody and Arch shall discuss in good faith (a) the name, branding, logos and marks to be used by the JV Entities following the Closing, (b) the provision by either Party or their respective Affiliates of any transition services, including information technology hosting and systems migration, as may be reasonably necessary or advisable for the JV Company to continue operating the Peabody Business and the Arch Business immediately after the Closing in substantially the same manner as operated by the respective Parties immediately prior to the Closing Date and (c) the engagement of any Third Parties, including consultants, software providers and other vendors, to provide services in connection with any such activities (it being acknowledged and agreed that Peabody shall be responsible for 66.5% of any amounts paid to any such Third Party by Arch or its Affiliates with Peabody’s prior written consent and Arch shall be responsible for 33.5% of any amounts paid to any such Third Party by Peabody or its Affiliates with Arch’s prior written consent).

SECTION 6.7. Non-Assignable Assets.

(a) To the extent that any asset (including any Permit) included in the Peabody Contributed Assets or the Arch Contributed Assets cannot be assigned to the JV Entities at the Closing without the prior Consent of any Person (or any attempted assignment without such prior Consent would result in a violation of Law or Contract or would materially and adversely affect the rights of the JV Entities thereto or thereunder) and such Consent has not been obtained as of the Closing Date, the Closing shall, subject to the satisfaction of the conditions set forth in Article VII, nevertheless take place on the terms set forth herein but the assignment of such Contract or Permit (each, a “Non-Assignable Asset”) to the applicable JV Entity shall not become effective unless and until such Consent has been obtained.

(b) Until such time as all Non-Assignable Assets have been assigned to the applicable JV Entity, the Parties shall, and shall cause their Affiliates and the JV Company to, (i) use their commercially reasonable efforts to obtain any required Consents for the assignment of such Non-Assignable Assets; provided, however, that (A) neither Party shall be obligated to pay any material amount as consideration therefor to, or make any material financial accommodation in favor of, or commence litigation against, the Person or Governmental Authority from whom such Consent is requested, other than filing and processing fees, and (B) neither Party shall take any action in connection with obtaining such Consent that would impose any conditions or obligations on any of the JV Entities after the Closing without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed) and (ii) to the greatest extent permitted by Law, establish arrangements under which a JV Entity (A) shall obtain the legal or economic claims, rights and benefits associated with such Non-Assignable Asset, (B) shall have dominion and control over such Non-Assignable Asset and (C) shall assume the legal and economic burden, obligations and Liabilities with respect to such Non-Assignable Asset and shall indemnify, defend and hold harmless the Person that is party to or otherwise holds such Non-Assignable Asset therefor. The Person that is party to or otherwise holds any such Non-Assignable Asset shall hold such Non-Assignable Asset in trust for the sole benefit and on behalf of the applicable JV Entity and shall, as soon as

67

practicable following receipt, pay over to the JV Company or its designees all receipts of cash relating to such Non-Assignable Asset until such time as such Non-Assignable Asset has been assigned to a JV Entity.

(c) When and if all Consents required for the assignment of any Non-Assignable Asset have been obtained, the assignment of such Non-Assignable Asset to the applicable JV Entity shall become automatically effective in accordance with the terms of this Agreement without the payment of any additional consideration.

(d) In the event that, as of the Closing, not all Governmental Approvals have been obtained with respect to the change in ownership and control of any Peabody Contributed Permit or any Arch Contributed Permit (including, as applicable, with respect to the transfer or reissuance of any such Permits to the JV Entities), to the extent that the JV Entities operate under any such Permits after the Closing pending the receipt of such approvals, any recipient of a notice of violation of, or failure to comply with, any such Permit shall notify the Parties and the JV Company immediately following receipt of such notice, and Peabody (in the case of any Peabody Contributed Permit) or Arch (in the case of any Arch Contributed Permit), as the case may be, in consultation with the other Party shall be entitled to undertake any actions and measures that are reasonably necessary and appropriate to cure, remedy or abate such violations or failure to comply as soon as reasonably practicable. In such event, the JV Entities shall cease any conduct and activities giving rise to such violations or failure to comply and shall provide the applicable Party with access to the relevant properties and facilities and information as may be reasonably requested or necessary in connection with such Party’s efforts to cure, remedy or abate such violations and failure to comply.

SECTION 6.8. Improper or Unintended Transfers.

(a) If, at any time after the Closing Date:

(i) a Party becomes aware that a JV Entity possesses any Excluded Asset, such asset shall be promptly transferred and conveyed to the applicable Peabody Entity or Arch Entity that held or was responsible for such Excluded Asset prior to the Closing; or

(ii) a Party becomes aware that Peabody, Arch or any of their respective Affiliates possesses any Contributed Asset, such asset shall be promptly transferred and conveyed to a JV Entity.

(b) Prior to the transfer of any asset pursuant to this Section 6.8, the Person receiving or possessing such asset shall hold such asset in trust for such other Person.

SECTION 6.9. Employee Matters.

(a) Prior to the Closing:

(i) the Parties shall cooperate in good faith to identify the Specified Employees (other than the Mining Site Employees) and, from time to time from the date of this Agreement to the Closing, the Parties shall update Sections 1.1(d) and 1.1(e) of the

68

Peabody Disclosure Letter and Sections 1.1(d) and 1.1(e) of the Arch Disclosure Letter, respectively, to reflect any mutually agreed changes to the lists of Specified Employees and Excluded Employees, in each case other than changes to the Mining Site Employees (which agreement shall not be unreasonably withheld, conditioned or delayed); provided, however, that, except as expressly set forth in this Section 6.9, no such updates shall affect the representations, warranties, covenants or agreements of the Parties under this Agreement;

(ii) the Parties shall, and shall cause their respective Affiliates to, take such steps as are required to transfer the employment of each Specified Employee to a Peabody Transferred Subsidiary or an Arch Transferred Subsidiary, as the case may be, if such Specified Employee is not already employed by a Peabody Transferred Subsidiary or an Arch Transferred Subsidiary;

(iii) each Party shall, and shall cause its Affiliates to, take such steps as are required to transfer the employment of (A) any employee who is employed by a Transferred Subsidiary and is not a Specified Employee and (B) any Inactive Employee, in each case to an Affiliate of such Party other than a Transferred Subsidiary;

(iv) the Parties shall cause the JV Company to make an offer of employment with a JV Entity (on terms and conditions to be determined by the JV Company after good faith consultation with the Parties), effective as at and from the Closing Date, to each Specified Employee (other than any Inactive Employees) who is not employed by a Transferred Subsidiary and whose employment is not expected to be transferred by the applicable Party to a Transferred Subsidiary prior to the Closing;

(v) the JV Company shall consider in good faith an application for employment from each Inactive Employee to the extent that such Inactive Employee is able to return to active employment within 180 days following the Closing Date or such later time as may be required by applicable Law, and the Party that previously employed such Inactive Employee will promptly notify the JV Company of such Inactive Employee’s ability to return to active employment; and

(vi) each Party shall not, and shall cause its Affiliates not to, discourage any employee to whom an offer of employment is made by a JV Entity pursuant to this Section 6.9(a) from accepting such offer.

(b) The Parties shall cooperate in good faith to integrate the compensation and benefit arrangements for the Transferred Employees in order to achieve as of the Closing Date an integrated set of Employee Benefit Plans that treats all Transferred Employees fairly, regardless of whether they were employed by Peabody or Arch prior to the Closing.

(c) The Parties shall cause the JV Company to provide each Transferred Employee whose employment is terminated within 120 days following the Closing Date due to redundancy by any JV Entity with eligibility for the severance benefits that would have been provided by Peabody and its Affiliates or Arch and its Affiliates, as the case may be, based on such Transferred Employee’s employer immediately prior to the Closing; provided, however,

69

that each Arch Business Employee listed on Section 6.9(c) of the Arch Disclosure Letter shall instead be eligible for severance benefits at the levels set forth on Section 6.9(c) of the Peabody Disclosure Letter and otherwise on the terms and conditions determined by the JV Company, including a requirement that the Transferred Employee execute and not revoke a release of claims that is intended to protect each of Peabody, Arch and their respective Affiliates from any claims. The Parties shall cause the JV Company to provide each Transferred Employee whose employment is terminated by any JV Entity from the end of such 120-day period through the 12-month anniversary of the Closing Date, regardless of whether such Transferred Employee was employed by Peabody and its Affiliates or Arch and its Affiliates prior to the Closing, with eligibility for severance benefits at the levels set forth on Section 6.9(c) of the Peabody Disclosure Letter and otherwise on the terms and conditions determined by the JV Company, including a requirement that the Transferred Employee execute and not revoke a release of claims that is intended to protect each of Peabody, Arch and their respective Affiliates from any claims.

(d) On the Closing Date, the Parties shall cause the JV Company, or one or more of its wholly-owned Subsidiaries, to assume all assets (other than any Excluded Assets) and all Liabilities relating to any Assumed Benefit Plans accrued prior to the Closing Date in respect of the Transferred Employees. From and after the Closing Date, the Parties shall cause the JV Entities to honor all obligations accrued under all Assumed Benefit Plans prior to the Closing in respect of each Transferred Employee in accordance with their terms as in effect immediately prior to the Closing. Except as required by applicable Law, effective as of the Closing Date, each Transferred Employee shall cease to actively participate in any Peabody Benefit Plan or Arch Benefit Plan (other than any Assumed Benefit Plan).

(e) The Parties shall cause the JV Company to reimburse each Party for any claims or Liabilities, including severance, redundancy or similar termination payments or benefits, arising out of or in connection with the termination of employment of any Mining Site Employee who is not a Transferred Employee by either Party or its Affiliates at or after the Closing if such termination occurs within three months following the Closing.

(f) Each Party shall, severally and not jointly, bear the full and sole responsibility and Liability for providing proper notifications to its and its Affiliates’ respective employees and any state or municipal agency or authority as may be required pursuant to the federal Workers’ Adjustment and Retraining Notification Act of 1988 (the “WARN Act”) or any similar state or municipal Law that may apply to any employment loss or the closure of work sites that may occur in connection with the transactions contemplated by this Agreement. Notwithstanding the foregoing or anything else in this Agreement to the contrary, the JV Entities shall be solely responsible for providing proper notifications under the WARN Act and for any claims or Liabilities, including severance, redundancy or similar termination payments or benefits, arising out of or in connection with the termination of employment of any Transferred Employees by any JV Entity after the Closing and the Parties shall cause the JV Entities not to terminate the employment of any Transferred Employee until at least the day following the Closing Date.

(g) The Parties intend that the transactions contemplated by this Agreement should not constitute a separation, termination or severance of employment of any Transferred

70

Employee prior to or upon the occurrence of the Closing for purposes of any severance plan of the Parties or their respective Affiliates or the WARN Act, and that each Transferred Employee will have continuous and uninterrupted employment immediately before and immediately after the Closing.

(h) The Parties shall cause the JV Entities to have in effect one or more defined contribution plans that each include a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (collectively, the “JV 401(k) Plan”) that will provide benefits to the Transferred Employees who are currently participating in Peabody’s 401(k) Savings Plan or Arch’s 401(k) Savings Plan (together with Peabody’s 401(k) Savings Plan, the “Business 401(k) Plans”) as of the Closing Date (or as soon as practicable thereafter). As soon as practicable following the Closing Date, each Party shall cause to be transferred from the applicable Business 401(k) Plan to the JV 401(k) Plan the assets and Liabilities relating to the account balances of the Transferred Employees in accordance with the terms of such Business 401(k) Plan, the JV 401(k) Plan, this Agreement and all applicable Laws, including the Code. Such transfer of assets and Liabilities shall consist of a transfer in cash of all account balances referred to in the first sentence of this Section 6.9(h), including (i) such Liabilities for the beneficiaries of the Transferred Employees, (ii) accrued benefit Liabilities arising under any applicable qualified domestic relations order and (iii) the balances of all participant loans under the Business 401(k) Plans. The Parties shall cause the JV Entities to direct the trustee of the JV 401(k) Plan to accept such transfers of assets and Liabilities from such Business 401(k) Plan. Upon such transfer of assets, the JV 401(k) Plan shall assume all Liabilities of each Party under the applicable Business 401(k) Plan with respect to all participants in such Business 401(k) Plan whose balances were transferred to the JV 401(k) Plan and their beneficiaries pursuant to such transfer, and such Party and such Business 401(k) Plan shall have no Liabilities to provide such participants with benefits under such Business 401(k) Plan following such transfer. Each Party shall, and shall cause the JV Company to, use its reasonable efforts to minimize the duration of any “blackout period” imposed in connection with each transfer of account balances from the Business 401(k) Plans to the JV 401(k) Plan. The Parties shall, and shall cause the JV Entities to, cooperate in effecting a transition of all outstanding 401(k) loans of Transferred Employees in a cost-efficient manner designed to prevent a deemed distribution from the applicable Business 401(k) Plan, either through plan amendment of the JV 401(k) plan to accept rollover of loans from such Business 401(k) Plan or through a bridge loan from the JV Company to any Transferred Employees with outstanding loan balances under such Business 401(k) Plan as of the Closing Date (or as soon as practicable thereafter). The JV Entities shall be solely responsible for all ongoing rights of or relating to the Transferred Employees for future participation (including the right to make contributions through payroll deductions) in the JV 401(k) Plan. The Parties shall, and shall cause the JV Entities to, cooperate in good faith to take the actions described in this Section 6.9(h) in a cost-efficient manner.

(i) Effective as of the Closing, each Transferred Employee who is a participant as of immediately prior to the Closing in a Peabody Pension Plan or Arch Pension Plan shall cease active participation in such applicable plan and service from and after the Closing with the JV Entities or any other employer other than Peabody or Arch, as the case may be, or their respective Affiliates shall not be taken into account for any purpose under such plan. Notwithstanding any provision of this Agreement to the contrary, following the Closing, (i) Peabody and its Affiliates shall retain sponsorship of each Peabody Pension Plan and all

71

assets and Liabilities arising out of or relating to such Peabody Pension Plan and (ii) Arch and its Affiliates shall retain sponsorship of each Arch Pension Plan and all assets and Liabilities arising out of or relating to such Arch Pension Plan, in each case, in respect of the Transferred Employees with vested rights thereunder in accordance with the terms of such plan as in effect from time to time and their applicable beneficiaries.

(j) Each Party shall pay to each Transferred Employee who participated in an annual cash incentive plan or program or any mining-level incentive plan or program sponsored by such Party or its Affiliates immediately prior to the Closing Date a prorated bonus in respect of the performance period in which the Closing occurs in an amount equal to the product of (x) the amount of the annual bonus or mining-level incentive plan bonus that would have been payable to such Transferred Employee under the applicable plan or program based on actual performance through the end of the applicable performance period as determined by such Party in its reasonable discretion pursuant to the terms of such plan or program, multiplied by (y) a fraction, the numerator of which is the number of days in such performance period that elapsed prior to the Closing Date, and the denominator of which is the number of days in such performance period. Such prorated bonus shall be paid, in the case of annual cash incentive plans or programs, at the time that bonuses under the applicable plan or program for such performance period are paid to similarly situated employees of the applicable Party and, in the case of mining-level incentive plans or programs, immediately prior to the Closing. For the avoidance of doubt, the JV Company shall not be required to provide any such Transferred Employee the opportunity to earn a bonus for the portion of the performance period in which the Closing occurs that elapsed prior to the Closing Date.

(k) From and after the Closing, the JV Entities shall give or cause to be given to each Transferred Employee full credit for all purposes (including for purposes of eligibility to participate or receive benefits, vesting, benefit accrual, level of benefits and early retirement subsidies and including for purposes of severance, vacation/paid time off, layoff and similar benefits and for any purposes as may be required under applicable Law), other than for benefit accrual purposes under any Arch Pension Plan or Peabody Pension Plan, under each Employee Benefit Plan established or maintained by any JV Entity in which Transferred Employees are eligible to participate on or after the Closing for service accrued or deemed accrued on or prior to the Closing with Arch or Peabody, as the case may be, or any Affiliate or predecessor thereof to the same extent that such credit was recognized by Arch or Peabody, as the case may be, or any Affiliate thereof under comparable benefit plans immediately prior to the Closing; provided, however, that such credit need not be provided to the extent that such credit would result in any duplication of benefits for the same period of service.

(l) With respect to each welfare benefit plan, program or arrangement maintained, sponsored or contributed to by the JV Entities after the Closing (collectively, the “JV Welfare Benefit Plans”) in which any Transferred Employee or spouse or dependent thereof may be eligible to participate on or after the Closing, the JV Entities shall (i) waive, or cause its Affiliates or insurance carrier to waive, all limitations as to preexisting conditions, actively-at-work requirements, exclusions and waiting periods, if any, with respect to participation and coverage requirements applicable to each Transferred Employee or spouse or dependent thereof, and any other restrictions that would prevent immediate or full participation by such Transferred Employee or spouse or dependent thereof, under such JV Welfare Benefit Plan, to the same

72

extent satisfied or waived under a comparable benefit plan of Arch or Peabody, as applicable, or any Affiliate thereof, and (ii) provide, or cause its Affiliates to provide, full credit to each Transferred Employee or spouse or dependent thereof for any co-payments, deductibles, out-of-pocket expenses and for any lifetime maximums paid by such Transferred Employee or spouse or dependent thereof under the comparable benefit plan of Arch or Peabody, as the case may be, or any Affiliate thereof during the relevant plan year up to and including the Closing Date as if such amounts had been paid under such JV Welfare Benefit Plan.

(m) In accordance with applicable Law, each Party shall pay each Transferred Employee employed by such Party or one of its Affiliates immediately prior to the Closing all wages accrued through the Closing Date, to the extent earned on or prior to the Closing Date. With respect to each Transferred Employee subject to U.S. payroll Taxes, pursuant to IRS Revenue Procedure 2004-53, each Party agrees to apply, and to cause the JV Company to apply, the “alternate” procedure for purposes of employee payroll reporting and withholding.

(n) Nothing in this Section 6.9 shall create any third-party beneficiary right in any Transferred Employee, or the dependent or beneficiary thereof, or any right to employment or continued employment or to a particular term or condition of employment. Nothing in this Section 6.9 shall be construed to establish, amend or modify any benefit or compensation plan, program, agreement or arrangement.

SECTION 6.10. Replacement of Financial Assurances. From and after the date of this Agreement, each Party shall, and shall cause its Affiliates to, use its commercially reasonable efforts to cause it and its Affiliates (other than the Transferred Subsidiaries) to be completely and unconditionally released, effective as of the Closing, from all obligations with respect to each Peabody Financial Assurance and each Arch Financial Assurance, as the case may be, including using its commercially reasonable efforts to cause the JV Company to arrange for and substitute, on or prior to the Closing, each Peabody Financial Assurance and each Arch Financial Assurance with a Financial Assurance made or delivered by a JV Entity in such form or amount as is reasonably acceptable to the Governmental Authority or other Person that holds or is the beneficiary of such Peabody Financial Assurance or Arch Financial Assurance, as the case may be. If the JV Company is unable or is not permitted under applicable Law to effectuate such substitution on or prior to the Closing with respect to any Peabody Financial Assurance or Arch Financial Assurance (an “Outstanding Financial Assurance”), (a) the Parties shall continue to use their commercially reasonable efforts to cause the JV Company to effectuate such substitution as soon as practicable following the Closing and (b) the applicable Party shall, and shall cause its Affiliates to, cause such Outstanding Financial Assurance to remain in place and not be terminated or modified in any way until such substitution is effectuated. Upon substitution of any Outstanding Financial Assurance, any collateral furnished by a Party or its Affiliate in respect of such substituted Outstanding Financial Assurance shall be returned to such Party or its Affiliate.

SECTION 6.11. Reorganizations. At or prior to the Closing, each Party shall cause, and shall reasonably cooperate with the other Party in causing, take all actions reasonably necessary to cause the transactions set forth in the reorganization plans set forth in Section 6.11 of the Peabody Disclosure Letter and Section 6.11 of the Arch Disclosure Letter, respectively (the “Pre-Closing Reorganization Plans” and such transactions, the “Pre-Closing

73

Reorganizations”), to occur, with only such changes as would not reasonably be expected to be adverse to the Peabody Business, the Arch Business or the JV Entities (including from a Tax perspective or otherwise). Each Party shall, and shall cause its Affiliates to, (a) consult with the other Party in good faith in connection with and in advance of any changes to the Pre-Closing Reorganizations and (b) keep the other Party reasonably informed on a timely basis with respect to all material activity concerning the status of the Pre-Closing Reorganizations. The agreements and instruments to effectuate the Pre-Closing Reorganizations shall be in form and substance reasonably acceptable to each Party.

SECTION 6.12. Insurance. From and after the Closing, (a) unless otherwise agreed by Peabody in writing, the Peabody Business, the Peabody Transferred Subsidiaries, the Peabody Contributed Assets and the Peabody Assumed Liabilities shall cease to be insured by the insurance policies and self-insured programs maintained by Peabody and its Affiliates and (b) the Arch Business, the Arch Transferred Subsidiaries, the Arch Contributed Assets and the Arch Assumed Liabilities shall cease to be insured by the insurance policies and self-insured programs maintained by Arch and its Affiliates, in each case with respect to events or circumstances that first occur on or after the Closing Date. With respect to events or circumstances that first occurred or existed prior to the Closing Date that are covered by occurrence-based insurance policies or self-insured programs maintained by Peabody, Arch or their respective Affiliates (the “Parent Insurance Policies”), from and after the Closing, each Party shall, and shall cause its Affiliates to, use its commercially reasonable efforts (at the JV Entities’ sole cost and expense) to cooperate with the JV Entities to submit any claims under the Parent Insurance Policies to the extent such coverage is available under the Parent Insurance Policies and the JV Entities elect to submit such claims and use its commercially reasonable efforts (at the JV Entities’ sole cost and expense) to cooperate in collecting the insurance proceeds with respect thereto; provided that, to the extent that coverage for any such claims is also available under any insurance policies of the JV Entities, the Parties shall cause the JV Entities to also submit claims under such insurance policies. The Parties shall cause the JV Entities to reimburse Peabody, Arch or their applicable Affiliates for any increased costs (including premiums) incurred by such Persons as a result of any such claims (other than claims that constitute Excluded Liabilities), as such amounts are determined in accordance with those policies and programs generally applicable from time to time; provided further that the JV Entities shall exclusively bear (and none of Peabody, Arch or their respective Affiliates shall have any obligation to repay or reimburse the JV Entities for) the amount of any deductibles, retentions or loss adjustments associated with claims under the Parent Insurance Policies (other than claims that constitute Excluded Liabilities) and shall be liable for all uninsured or uncovered amounts of such claims. For the avoidance of doubt, except as expressly set forth in this Agreement, Peabody, Arch and their respective Affiliates shall retain all rights to control their respective insurance policies and programs, notwithstanding whether any such policies or programs apply to any Liabilities of the JV Entities, and nothing herein shall require Peabody, Arch or any of their respective Affiliates to maintain any insurance after the Closing.

SECTION 6.13. Termination of Affiliate Contracts and Intercompany Accounts.

(a) Except for those Contracts set forth on Section 6.13(a) of the Peabody Disclosure Letter, Peabody shall, and shall cause its Affiliates to, cause any Contracts, Liabilities or other obligations relating to the Peabody Business between Peabody or any of its Affiliates, on

74

the one hand, and any Affiliate of Peabody, on the other hand, to be terminated or extinguished immediately prior to the Closing, and the parties to such Contracts, Liabilities or obligations shall execute customary releases reasonably satisfactory to Arch to ensure that the JV Entities (including the Peabody Transferred Subsidiaries) shall have no Liability or obligation thereunder.

(b) Except for those Contracts set forth on Section 6.13(b) of the Arch Disclosure Letter, Arch shall, and shall cause its Affiliates to, cause any Contracts, Liabilities or other obligations relating to the Arch Business between Arch or any of its Affiliates, on the one hand, and any Affiliate of Arch, on the other hand, to be terminated or extinguished immediately prior to the Closing, and the parties to such Contracts, Liabilities or obligations shall execute customary releases reasonably satisfactory to Peabody to ensure that the JV Entities (including the Arch Transferred Subsidiaries) shall have no Liability or obligation thereunder.

SECTION 6.14. Further Assurances. Each Party shall, and shall cause its Affiliates to, from time to time after the Closing Date and without further consideration, execute, acknowledge and deliver such other instruments of conveyance and transfer and take such other actions and execute and deliver such other documents, assignments, deeds, certifications and further assurances as any Party may reasonably request to carry out, evidence and confirm the intended purposes of this Agreement and the other Transaction Documents or the transactions contemplated hereby or thereby.

SECTION 6.15. Bulk Transfer Laws. Each Party hereby waives compliance by it and each of its Affiliates with the notice requirements and other applicable provisions relating to transferee liability of the “bulk-sale” or “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the transfer of any or all of the Peabody Contributed Assets or the Arch Contributed Assets to any of the JV Entities in connection with the transactions contemplated by this Agreement.

SECTION 6.16. Confidentiality. From the date hereof until the Closing, each Party shall, and shall cause its Affiliates and its and their respective Representatives to, keep confidential and not disclose to any other Person, or use for their own benefit or the benefit of any other Person, any confidential and non-public information to the extent relating to the Peabody Business or the Arch Business, as the case may be, in accordance with the provisions of the Confidentiality Agreement. The obligations of each Party under this Section 6.16 shall not apply to information which (a) is used by such Party in its other businesses, (b) is or becomes generally available to the public without breach of such Party’s obligations under this Section 6.16 or (c) is required to be disclosed by applicable Law or any Order. The Parties expressly acknowledge and agree that, in the event that Closing occurs, the Confidentiality Agreement shall be terminated in its entirety effective as of the Closing Date, and all obligations with respect to confidentiality shall be governed by the provisions of the LLC Agreement.

SECTION 6.17. Resignations. Each Party shall use its commercially reasonable efforts to cause to be delivered to the JV Company on the Closing Date resignation letters of such members of the board of directors (or comparable governing body) and officers of each Transferred Subsidiary as the other Party shall have requested in writing at least ten Business

75

Days prior to the Closing Date, such resignation letters to include customary mutual release of liability and waiver provisions and to be effective as of the Closing.

SECTION 6.18. Guarantees.

(a) Peabody Guarantee. Peabody hereby absolutely, irrevocably and unconditionally guarantees to Arch, the JV Company and their respective Affiliates the full and timely performance by any controlled Affiliate of Peabody of any agreements, covenants or other obligations that are required to be performed or satisfied by such Affiliate under any of the Transaction Documents to the extent arising at or after the Closing (including any obligations to make payments in respect of capital contributions under the LLC Agreement). If such Affiliate fails to perform or satisfy any of such agreements, covenants or other obligations, then Peabody will itself duly and promptly perform or satisfy, as the case may be, such agreements, covenants or other obligations, or cause the same to be duly and promptly performed or satisfied, in each case as if Peabody were itself the obligor with respect to such agreements, covenants and obligations. The guarantee provided in this Section 6.18(a) shall become effective as of the Closing.

(b) Arch Guarantee. Arch hereby absolutely, irrevocably and unconditionally guarantees to Peabody, the JV Company and their respective Affiliates the full and timely performance by any controlled Affiliate of Arch of any agreements, covenants or other obligations that are required to be performed or satisfied by such Affiliate under any of the Transaction Documents to the extent arising at or after the Closing (including any obligations to make payments in respect of capital contributions under the LLC Agreement). If such Affiliate fails to perform or satisfy any of such agreements, covenants or other obligations, then Arch will itself duly and promptly perform or satisfy, as the case may be, such agreements, covenants or other obligations, or cause the same to be duly and promptly performed or satisfied, in each case as if Arch were itself the obligor with respect to such agreements, covenants and obligations. The guarantee provided in this Section 6.18(b) shall become effective as of the Closing.

SECTION 6.19. Right of First Refusal.

(a) From and after the Closing, if either Party or any of their respective Affiliates (the “Offering Party”) receives a bona fide written offer (an “Offer”) from any Third Party (the “Offeror”) to purchase or otherwise acquire any or all of the ROFR Assets (the “Offered Assets”) in any transaction or series of related transactions on terms that the Offering Party is willing to accept, the Offering Party shall, as promptly as practicable but in no event later than five Business Days after the Offering Party’s receipt of such Offer, provide written notice thereof (the “Offer Notice”) to the JV Company and each member of the JV Company that is not an Affiliate of the Offering Party. The Offer Notice shall describe in reasonable detail the terms of such Offer, including (i) a description of the Offered Assets, (ii) the type and amount of consideration to be paid for such Offered Assets and the terms of the payment thereof (the “Offer Price”) and (iii) the identity of the Offeror (including, to the Knowledge of the Offering Party, the identity of any Persons that Control the Offeror), and shall include copies of all documentation relating to the Offer, including all offer letters, term sheets and written draft Contracts proposed to be entered into in connection therewith.

76

(b) During the 30-day period following the receipt of such Offer Notice (5:00 p.m. (New York City time) on such 30th day, the “Offer Deadline”), the JV Company shall have the right to irrevocably elect to purchase, at the Offer Price (provided that if any portion of the Offer Price includes non-cash consideration, the JV Company may substitute cash of equivalent value), all (but not less than all) of the Offered Assets by providing written notice of such election to purchase the Offered Assets (a “ROFR Election Notice”) to the Offering Party on or prior to the Offer Deadline.

(c) A ROFR Election Notice shall constitute a binding commitment of the JV Company to purchase all of the Offered Assets. If a valid ROFR Election Notice is delivered prior to the Offer Deadline, the closing of the purchase of the Offered Assets by the JV Company shall occur not later than the later of (i) 30 days after the delivery of the ROFR Election Notice and (ii) such later date as may be necessary to comply with the requirements of any applicable Law or to obtain any necessary Governmental Approvals.

(d) If a valid ROFR Election Notice has not been delivered by the Offer Deadline, then for a period of 60 days immediately following the Offer Deadline (which period shall be extended by any period of time required to comply with applicable Law or the requirements of any Governmental Authority), the Offering Party may sell the Offered Assets to the Offeror for consideration not less than the Offer Price and otherwise on the terms and conditions described in the Offer Notice. If such sale is not consummated within such period or is proposed to be made for consideration less than the Offer Price or otherwise not on the same terms and conditions or to the Offeror described in the Offer Notice, the Offering Party shall not, and shall not permit its Affiliates to, sell or dispose of the Offered Assets unless and until a further Offer Notice has been delivered (and the procedures set forth in this Section 6.19 have been complied with in connection with such further Offer Notice) with respect to such Offered Assets.

SECTION 6.20. Intellectual Property Matters.

(a) Peabody and its Affiliates hereby unconditionally grant to the JV Entities as of the Closing a non-exclusive, royalty-free, perpetual, irrevocable, fully paid-up license (with the right to grant sublicenses) to use the Peabody Retained IP (other than the Peabody Retained Marks) as it exists as of the Closing; provided, however, that the Parties shall cause the JV Entities not to sublicense or disclose any confidential Peabody Retained IP to any Person unless such Person is subject to a customary obligation of confidentiality. Each of Peabody and its Affiliates, on the one hand, and the JV Entities, on the other hand, may modify or improve the Peabody Retained IP licensed pursuant to this Section 6.20(a), and the Person making such modifications or improvements shall own all right, title and interest therein.

(b) Arch and its Affiliates hereby unconditionally grant to the JV Entities as of the Closing a non-exclusive, royalty-free, perpetual, irrevocable, fully paid-up license (with the right to grant sublicenses) to use the Arch Retained IP (other than the Arch Retained Marks) as it exists as of the Closing; provided, however, that the Parties shall cause the JV Entities not to sublicense or disclose any confidential Arch Retained IP to any Person unless such Person is subject to a customary obligation of confidentiality. Each of Arch and its Affiliates, on the one hand, and the JV Entities, on the other hand, may modify or improve the Arch Retained IP

77

licensed pursuant to this Section 6.20(b), and the Person making such modifications or improvements shall own all right, title and interest therein.

(c) From and after the Closing, except as expressly provided in this Section 6.20(c), the Parties shall cause the JV Entities not to use the Peabody Retained Marks or the Arch Retained Marks alone or together with other words, logos, symbols or designs in any form, variation or manner in connection with any business that the JV Entities may thereafter conduct. The JV Entities shall use commercially reasonable efforts to remove and cease use of all Peabody Retained Marks or Arch Retained Marks, including removing or replacing all logos and signage on tangible items included in the Contributed Assets, as promptly as reasonably practicable but in any event no later than the date that is six months after the Closing Date; provided, however, that during such six-month period, the JV Entities may continue to use any tangible items included in the Contributed Assets, including the existing signage and the existing stock of letterhead, labels, promotional materials and other documents and materials, that contain the Peabody Retained Marks and the Arch Retained Marks in a manner consistent with (and for a purpose no different from) the use of such Peabody Retained Marks or Arch Retained Marks by Peabody or Arch, as the case may be, and their respective Affiliates prior to the Closing.

SECTION 6.21. Tax Covenants.

(a) Tax Returns.

(i) Pre-Closing Tax Returns. From and after the Closing, Peabody shall prepare or cause to be prepared all Tax returns required to be filed by the Peabody Transferred Subsidiaries or, other than Tax returns related to Income Taxes, with respect to the Peabody Contributed Assets for any Pre-Closing Tax Period (the “Peabody Prepared Returns”), and Arch shall prepare or cause to be prepared all Tax returns required to be filed by the Arch Transferred Subsidiaries or, other than Tax returns related to Income Taxes, with respect to the Arch Contributed Assets for any Pre-Closing Tax Period (the “Arch Prepared Returns”). Except as otherwise required by applicable Law, each of Peabody and Arch shall prepare such Tax returns in accordance with past practice. Peabody and Arch shall each deliver to the JV Company all Peabody Prepared Returns and Arch Prepared Returns, together with all supporting documentation, no later than ten days prior to the due date for filing such Tax return, and, if any Peabody Prepared Return or any Arch Prepared Return would reasonably be expected to result in or otherwise affect material Taxes of any JV Entity in any Post-Closing Taxable Period, Peabody or Arch, as the case may be, shall also deliver such Tax return, together with all supporting documentation to Arch or Peabody, as the case may be, no later than ten days prior to the due date for filing such Tax return, for review and reasonable comment by the JV Company and Arch or Peabody, as the case may be, and the party filing such Tax return shall incorporate any reasonable comments received no later than five days prior to the due date for filing such Tax return. Peabody and Arch shall use commercially reasonable efforts to determine which of Peabody, Arch or the JV Company shall file such Tax return. If after complying with the immediately preceding sentence in good faith, Peabody and Arch are unable to agree on which of Peabody, Arch or the JV Company is responsible for filing such Tax return, then the JV Company shall be responsible for filing such Tax return. If the JV Company files any Tax return pursuant

78

to this Section 6.21(a)(i) and if such Tax return shows Taxes as due and owing, Peabody or Arch, as applicable, shall pay the amount of Contributor Taxes with respect to such Tax return to the JV Company no later than the due date for filing such Tax return and the JV Company shall remit such Taxes to the applicable Governmental Authority. If either Peabody or Arch files any Tax return pursuant to this Section 6.21(a)(i), such Tax return shows Taxes as due and owing, and such Taxes were specifically included in Peabody Net Working Capital or Arch Net Working Capital, as the case may be, as finally determined pursuant to Section 3.5(c), then the JV Company shall pay the amount of such identified Taxes to Peabody or Arch no later than the due date for filing such Tax return and Peabody or Arch, as the case may be, shall remit such Taxes to the applicable Governmental Authority.

(ii) Straddle Period Tax Returns. The JV Company shall prepare and file or cause to be prepared and filed all Tax returns required to be filed by the Peabody Transferred Subsidiaries or the Arch Transferred Subsidiaries or, other than Tax returns related to Income Taxes, with respect to the Peabody Contributed Assets or the Arch Contributed Assets, in each case, for any Straddle Period. Except as required by applicable Law, the JV Company shall prepare such Tax returns in accordance with past practice. With respect to any material Straddle Period Tax return (which, for the avoidance of doubt, shall include any Tax return that shows a liability of greater than $500,000) or to the extent any other Straddle Period Tax return is not prepared on a basis consistent with past practice, the JV Company shall deliver a copy of such Tax return to each of Peabody and Arch, together with all supporting documentation, no later than ten days prior to the due date for filing such Tax return, for their review and reasonable comment. The JV Company shall incorporate any reasonable comments to such Tax return provided by the applicable Party no later than five days prior to the due date for filing such Tax return. Peabody or Arch, as applicable, shall pay the amount of Contributor Taxes with respect to such Tax return to the JV Company no later than the due date for filing such Tax return and the JV Company shall remit such Taxes to the applicable Government Authority.

(iii) Amended Returns. From and after the Closing, neither Party shall file an amended Tax return (A) with respect to a Straddle Period, or (B) with respect to a Pre-Closing Tax Period if the filing of such amended Tax return would reasonably be expected to result in or otherwise affect material Taxes of any JV Entity in any Post-Closing Taxable Period, in each case without the consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(b) Cooperation. From and after Closing, (i) the JV Company, Peabody and Arch shall use their respective commercially reasonable efforts to cooperate with the reasonable requests of the JV Company, Peabody or Arch, as applicable, in connection with the payment of Taxes, the filing of Tax returns and the conduct and settlement of any Tax Contest. Such cooperation shall include the provision by the JV Company to Peabody or Arch, as applicable, or the provision by Peabody or Arch, as applicable, to the JV Company of records and information and access to employees reasonably requested in connection with the preparation and filing of any Tax return or the conduct or settlement of any Tax Contest and (ii) Peabody, Arch and, to the extent any such books and records are held by or are transferred to the JV Entities, the JV

79

Entities shall retain all books and records with respect to Pre-Closing Taxes for a period of at least seven years following the Closing Date.

(c) Tax Contests. From and after the Closing:

(i) the JV Company shall promptly notify (A) Peabody upon receipt by any JV Entity of any written notice of any Tax Contest for which any Person would be entitled to make a Claim for indemnification under Section 8.2 or that would give rise to a Pre-Closing Tax Asset and (B) Arch upon receipt by any JV Entity of any written notice of any Tax Contest for which any Person would be entitled to make a Claim for indemnification under Section 8.3 or that would give rise to a Pre-Closing Tax Asset. Any such notice shall specify whether such Tax Contest would reasonably be expected to result in or otherwise affect any Taxes of any JV Entity in any Post-Closing Taxable Period;

(ii) Peabody shall promptly notify Arch upon receipt by Peabody or any of its Affiliates of any written notice of any Tax Contest if the resolution of such Tax Contest would reasonably be expected to result in or otherwise affect any Taxes of any JV Entity in any Post-Closing Taxable Period;

(iii) Arch shall promptly notify Peabody upon receipt by Arch or any of its Affiliates of any written notice of any Tax Contest if the resolution of such Tax Contest would reasonably be expected to result in or otherwise affect any Taxes of any JV Entity in any Post-Closing Taxable Period; and

(iv) (A) Peabody shall have the sole right to direct and control the defense of any Tax Contests for which any Person be entitled to make a Claim for indemnification under Section 8.2 or that would give rise to a Pre-Closing Tax Asset and (B) Arch shall have the sole right to direct and control the defense of any Tax Contests for which any Person would be entitled to make a Claim for indemnification under Section 8.3 or that would give rise to a Pre-Closing Tax Asset; provided, however, in each case, that if the conduct or settlement of any Tax Contest would reasonably be expected to result in or otherwise affect any Taxes of any JV Entity in any Post-Closing Taxable Period, the controlling Party shall keep the other Party reasonably informed as to the progress of such Tax Contest and shall not enter into any settlement or compromise of such Tax Contest in any manner that would reasonably be expected to result in or otherwise affect any Taxes of any JV Entity in any Post-Closing Taxable Period without the other Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed). No provision of this Section 6.21(c)(iv) shall apply to Tax Contests relating to Income Taxes (other than Tax Contests related to Peabody Prepared Returns and Arch Prepared Returns), and Peabody or Arch, as applicable, shall have exclusive control of any such Tax Contest.

(d) The failure of any Party or the JV Company to notify any Party of any Tax Contest pursuant to Section 6.21(c) shall not relieve such Party from any liability that it might have with respect to such Tax Contest, except to the extent such Party demonstrates that its

80

defense of such Tax Contest is actually and materially prejudiced by the failure to promptly give such notice.

(e) Conflict with Other Provisions. To the extent that the provisions of this Section 6.21 are inconsistent with or conflict with any other provisions under this Agreement, the provisions of this Section 6.21 shall control.

SECTION 6.22. Arch Royalty Credits. Prior to the Closing, the Parties shall cooperate in good faith to establish arrangements under which, from and after the Closing, (i) the Arch Royalty Credits (when and if issued) shall be transferred to the JV Company or one or more of its wholly-owned Subsidiaries, (ii) the JV Company shall use commercially reasonable efforts to monetize the value of such Arch Royalty Credits, including by using such Arch Royalty Credits in lieu of a monetary payment for a bonus bid for a coal lease sale or as a monetary credit against any Royalties due under any federal coal lease and (iii) Arch or its Affiliates shall, from and after the Closing, obtain all economic claims, rights and benefits, on a dollar-for-dollar basis, associated with such Arch Royalty Credits (as and when such Arch Royalty Credits are monetized), in each case to the fullest extent permitted under applicable Law.

SECTION 6.23. Federal Leases.

To the extent the actions set forth in the immediately preceding sentence are pending as of the Closing Date, the Parties shall, to the extent such actions are contemplated or permitted by applicable Law, cause the JV Entities to use their reasonable best efforts to effectuate such actions as soon as reasonably practicable after the Closing Date.

(a) any inaccuracy in, or breach of, a Peabody Fundamental Representation or the representations and warranties set forth in Section 4.10; provided that, solely for purposes of determining the amount of any Losses resulting from such inaccuracy or breach, such determination shall be made without giving effect to any limitation as to “materiality”, “material adverse effect” or “Peabody Material Adverse Effect” set forth in such representation and warranty;

SECTION 8.5. Limitation of Liability.

(a) A Notice of Claim under this Article VIII based on any inaccuracy in, or breach of, a representation or warranty or any failure to perform or comply with any covenant or agreement must be delivered prior to the expiration of the applicable Survival Period, and any claim not made prior to the expiration of such Survival Period shall be of no force or effect and shall not give rise to any obligation of the Indemnifying Party to indemnify, defend or hold harmless any Indemnified Party. Notwithstanding the foregoing, if, before 5:00 p.m. (New York City time) on the last day of the Survival Period, an Indemnified Party shall have delivered a Notice of Claim in accordance with Section 8.6 and any claim identified in such Notice of Claim shall not have been finally resolved or disposed of at such date, the representation, warranty,

85

covenant or agreement that is the subject of such claim shall, to the extent of such claim only, survive until such claim has been fully and finally resolved or disposed of in accordance with the terms hereof.

(b) Notwithstanding anything in this Agreement to the contrary but subject to Section 8.5(d), the maximum aggregate liability of Peabody, on the one hand, and Arch, on the other hand, in respect of the indemnities contained in Section 8.2(a) and Section 8.3(a), respectively, shall not exceed the Indemnity Cap Amount.

(c) Notwithstanding anything in this Agreement to the contrary but subject to Section 8.5(d), neither Party shall be liable to the other Party or its Affiliates or to the JV Company, whether in contract, tort (including negligence and strict liability) or otherwise, at law or in equity, pursuant to this Agreement for any consequential, special, incidental, indirect, punitive or similar damages whatsoever, including lost profits (other than lost profits that are proven to be direct damages), diminution of value or damages calculated on multiples of earnings or other metrics, other than consequential, special, incidental, indirect, punitive or similar damages paid to a Third Party in respect of a Third Party Claim.

(d) Notwithstanding anything in this Agreement to the contrary, the limitations set forth in Sections 8.5(b) and 8.5(c) shall not be applicable to any Losses of any Indemnified Party that arise out of or in connection with fraud, intentional misrepresentation or willful misconduct.

(e) Notwithstanding anything to the contrary in this Agreement, the representations and warranties in Section 4.10 (other than the representations and warranties in Section 4.10(c)) and the representations and warranties in Section 5.10 (other than the representations and warranties in Section 5.10(c)) may only be relied upon for purposes of liability for taxable periods (or portions thereof) ending on or prior to the Closing Date.

SECTION 8.6. Notice of Claim.

(a) A Person that has suffered or incurred a Loss for which such Person may be entitled to make a claim for indemnification (a “Claim”) under this Agreement (the “Indemnified Party”) shall give written notice to the party obligated to indemnify the Indemnified Party for such Claim (the “Indemnifying Party”) of such Claim (a “Notice of Claim”) within 30 days of becoming aware that it has suffered such Loss. The Notice of Claim shall specify whether the Claim arises as a result of a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), and shall include a copy of all papers (if any) served with respect to such Third Party Claim, or whether the Claim does not so arise (a “Direct Claim”), and shall also specify with reasonable particularity, to the extent that the information is available, the factual basis for the Claim and the amount of the Claim.

(b) Each of Peabody and Arch shall be entitled to provide a Notice of Claim on behalf of the JV Company in respect of a Claim for indemnification under Section 8.2 and Section 8.3, respectively, and shall be entitled to make elections on behalf of and otherwise control any such Claim on behalf of the JV Company as the Indemnified Party in respect of such

86

Claim under this Article VIII, without duplication of recovery for the same Loss by either Party, on the one hand, and the JV Company, on the other hand.

(c) The failure of the Indemnified Party to notify the Indemnifying Party promptly as required by Section 8.6(a) shall not relieve the Indemnifying Party of any liability that it might have to any Indemnified Party, except to the extent that the Indemnifying Party demonstrates that its defense of any Third Party Claim is actually and materially prejudiced by the Indemnified Party’s failure to promptly give such notice.

SECTION 8.7. Direct Claims. With respect to any Direct Claim, following receipt of a Notice of Claim from the Indemnified Party, the Indemnifying Party shall have 45 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If the Indemnified Party and the Indemnifying Party agree at or prior to the expiration of such 45-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed-upon amount of the Claim, failing which the Indemnified Party is free to pursue all rights and remedies available to it pursuant to this Agreement to enforce its indemnification rights set forth in this Agreement.

SECTION 8.8. Defense of Third Party Claims.

(a) Subject to Section 8.8(d), upon receiving a Notice of Claim relating to any Third Party Claim, the Indemnifying Party shall be entitled to participate in the investigation and defense of such Third Party Claim and, if it so elects, to assume the investigation and defense of such Third Party Claim with counsel selected by the Indemnifying Party (and reasonably acceptable to the Indemnified Party). The Indemnified Party shall cooperate in good faith in any such defense. The Indemnified Party shall have the right, at its own cost and expense, to participate in the defense of any Third Party Claim with counsel selected by it subject to the Indemnifying Party’s right to control the defense thereof.

(b) In order to assume the investigation and defense of a Third Party Claim, the Indemnifying Party must give the Indemnified Party written notice of its election and acceptance of the defense within 20 days of the Indemnifying Party’s receipt of the Notice of Claim.

(c) Subject to Section 8.8(d), if the Indemnifying Party assumes the investigation and defense of a Third Party Claim:

(i) the Indemnifying Party will pay for all costs and expenses of the investigation and defense of the Third Party Claim except that the Indemnifying Party will not, so long as it diligently conducts such defense, be liable to the Indemnified Party for any fees of other counsel or any other expenses with respect to the defense of the Third Party Claim incurred by the Indemnified Party after the date the Indemnifying

87

Party validly exercised its right to assume the investigation and defense of the Third Party Claim;

(ii) the Indemnifying Party will reimburse the Indemnified Party for all reasonable costs and expenses incurred by the Indemnified Party in connection with the investigation and defense of the Third Party Claim prior to the date the Indemnifying Party validly exercised its right to assume the investigation and defense of the Third Party Claim; and

(iii) if the Indemnifying Party thereafter fails to defend the Third Party Claim within a reasonable time, the Indemnified Party shall be entitled to assume such defense and the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to the Third Party Claim.

(d) Where the named parties to any Third Party Claim include the Indemnified Party as well as the Indemnifying Party and the Indemnified Party determines in good faith, based on written advice from its legal counsel, that joint representation would be inappropriate due to the actual or potential differing interests between them or there may be one or more legal defenses available to the Indemnified Party which are different from or in addition to those available to the Indemnifying Party, and the Indemnified Party notifies the Indemnifying Party in writing that it elects to retain separate counsel, the Indemnifying Party shall not have the right to assume the defense of such Third Party Claim on behalf of the Indemnified Party and shall be liable to pay the reasonable fees and expenses of counsel of the Indemnified Party.

(e) If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable Law to incur losses or make a payment to any Third Party with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may incur such Losses or make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment. If the amount of any liability of the Indemnified Party under such Third Party Claim, as finally determined, is less than the amount that was paid by the Indemnifying Party to the Indemnified Party, the Indemnified Party shall, forthwith after the receipt of the difference from the Third Party, pay the amount of such difference, together with any interest thereon paid by the Third Party to the Indemnified Party, to the Indemnifying Party. In addition, the Indemnifying Party shall post all security required by any court, regulatory body or other authority having jurisdiction, including without limitation, for purposes of enabling the Indemnifying Party to contest any Third Party Claim.

(f) If the Indemnified Party undertakes the defense of the Third Party Claim, the Indemnifying Party will not be bound by any compromise or settlement of the Third Party Claim effected without the consent of the Indemnifying Party (which consent may not be unreasonably withheld, conditioned or delayed) unless such compromise or settlement includes an unconditional release of the Indemnifying Party from all liability and obligations arising from such Third Party Claim.

(g) The Indemnified Party and the Indemnifying Party shall cooperate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with

88

respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

(h) The Indemnifying Party will not be permitted to compromise and settle or to cause a compromise and settlement of a Third Party Claim without the prior written consent of the Indemnified Party, which consent may not be unreasonably withheld, conditioned or delayed, unless:

(i) the terms of the compromise and settlement require only the payment of money for which the Indemnified Party is entitled to full indemnification under this Agreement and the Indemnifying Party agrees to timely pay such amount in full; and

(ii) the Indemnified Party is not required to admit any wrongdoing, take or refrain from taking any action, acknowledge any rights of the Person making the Third Party Claim or waive any rights that the Indemnified Party may have against the Person making the Third Party Claim.

SECTION 8.9. No Duplicate Recovery. For the avoidance of doubt, to the extent any Loss gives rise to a claim by an Indemnified Party under more than one provision of this Agreement (including multiple representations and warranties or covenants or agreements), or under more than one clause of Section 8.2, 8.3 or 8.4, such Indemnified Party may seek recovery under any and all such provisions and clauses; provided, however, that any Loss under this Agreement shall be determined without duplication of recovery for the same Loss by reason of the facts giving rise to such Loss arising out of an Assumed Liability, an Excluded Liability or constituting a breach of more than one representation, warranty, covenant or agreement.

SECTION 8.10. Duty to Mitigate; Adjustments. Each Indemnified Party shall have a duty to take reasonable steps to mitigate any Losses which it may suffer or incur by reason of the breach or failure to perform of any representation, warranty, covenant or obligation of any Indemnifying Party under this Agreement, including diligently pursuing any possible indemnification, counterclaim or other action against third parties relating to the cause or effect of the Loss; provided that no Indemnified Party shall have any duty to make any claim under its own insurance coverage for an indemnification obligation of an Indemnifying Party. The amount for which any Indemnifying Party shall be liable with respect to any Loss incurred by any Indemnified Party shall be reduced to the extent that such Indemnified Party actually realizes any proceeds (net of any costs or expenses incurred by such Indemnified Party in the collection of such proceeds, including any deductible for or retention under any insurance policy and any increase in the premium for such policies) recovered from third parties (including insurers) with respect to such Loss. If an Indemnified Party receives an indemnification payment hereunder from any Indemnifying Party in respect of a Loss and subsequently actually recovers any proceeds from third parties with respect to such Loss, such Indemnified Party shall return such indemnification payment to such Indemnifying Party up to the amount of such proceeds (net of any costs or expenses incurred by such Indemnified Party in the collection of such proceeds, including any deductible for or retention under any insurance policy and any increase in the premium for such policies).

89

SECTION 8.11. Exclusive Remedy. Except as permitted by Section 3.5, 6.8, 6.18, 6.19 or 10.8, from and after the Closing, indemnification pursuant to this Article VIII shall be the sole and exclusive remedy for the Parties for monetary damages for any inaccuracy in, or breach of, a representation or warranty or any failure to perform or comply with any covenant or agreement contained in this Agreement (without limitation of any remedies available under any other Transaction Document). The Parties agree that no payment for any Loss pursuant to this Article VIII shall affect the Parties’ (or their respective Affiliates’) ownership interests in the JV Company.

SECTION 8.12. Waiver of Right to Rescission. Arch and Peabody acknowledge that, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach on or prior to the Closing Date of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement. As the payment of money shall be adequate compensation, following Closing, Arch and Peabody waive any right to rescind this Agreement or any of the transactions contemplated hereby.

ARTICLE IX

(A) this Agreement shall automatically terminate, without any further action by either Party, at 5:00 p.m. (New York City time) on September 18, 2020 if the Closing has not occurred prior to such date; provided, however, that this Agreement shall not terminate pursuant to this Section 9.1(e)(i)(A) if the Terminating Party has failed to perform its obligations pursuant to Section 6.4; and

(B) unless the Closing has occurred, this Agreement may be terminated by the Non-Terminating Party at any time after the delivery of such Continuation Notice; or

(ii) if the Non-Terminating Party does not deliver a valid and timely Continuation Notice, this Agreement shall automatically terminate, without any further action by either Party, at the Continuation Deadline if the Closing has not occurred prior to such date.

91

SECTION 10.2. Governing Law; Consent to Jurisdiction; Venue.

(a) This Agreement, and any non-contractual claim arising out of the transactions contemplated by this Agreement, shall be governed by, and construed in accordance with, the Laws of the State of New York, regardless of Laws that might otherwise govern under applicable principles of conflict of laws thereof.

(b) Each of the Parties hereby (i) agrees that any suit, action or other proceeding arising directly or indirectly out of, under or relating to this Agreement, its negotiation or the transactions contemplated hereby will be heard and determined exclusively in the State and Federal Courts located in the Borough of Manhattan in the City and State of New York (and each agrees that no such suit, action or other proceeding relating to this Agreement will be brought by it or any of its Affiliates except in such court), subject to any appeal; and (ii) irrevocably and unconditionally submits to the exclusive jurisdiction of any such court in any such suit, action or other proceeding, irrevocably and unconditionally waives the defense of an inconvenient forum to the maintenance of any such suit, action or other proceeding and agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from any such court. Each of the Parties further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 10.1 will be effective service of process for any suit, action or other proceeding in New York with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. The Parties hereby agree that final judgment in any such suit, action or other proceeding will be conclusive, subject to any appeal, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

SECTION 10.3. Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, AND COVENANTS THAT SUCH PARTY WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF THIS AGREEMENT OR THE SUBJECT MATTER HEREOF OR IN ANY WAY CONNECTED WITH THE DEALINGS OF ANY

95

PARTY IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREIN, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER IN CONTRACT, TORT OR OTHERWISE. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR OTHER PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 10.3.

SECTION 10.4. Entire Agreement. This Agreement, taken together with the Peabody Disclosure Letter, the Arch Disclosure Letter, the Confidentiality Agreement, the Common Interest Agreement and the other Transaction Documents, constitutes the entire agreement between the Parties and supersedes all prior agreements, understandings, negotiations and discussions, whether written or oral, between the Parties with respect to the subject matter hereof and thereof.

SECTION 10.5. Third-Party Beneficiaries. The JV Company shall be considered to be a third-party beneficiary of the provisions of this Agreement. Except as expressly set forth in Article VIII or this Section 10.5, this Agreement is for the sole benefit of the Parties and their successors and permitted assigns and does not confer upon any Person other than the Parties any rights or remedies.

SECTION 10.6. Severability. If any provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, all other provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party or such Party waives its rights under this Section 10.6 with respect thereto. Upon such determination that any term or other provision is invalid, illegal or unenforceable in any respect, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 10.7. Extension; Waiver. At any time prior to the Closing, the Parties may (a) extend the time for the performance of any of the obligations or other acts of the other Party, (b) waive any inaccuracies in the representations and warranties contained in this Agreement, (c) waive compliance with any covenants and agreements contained in this Agreement or (d) waive the satisfaction of any of the conditions contained in this Agreement. Any agreement on the part of either Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

SECTION 10.8. Specific Performance. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is

96

accordingly agreed that, prior to the termination of this Agreement pursuant to Article IX, the Parties shall be entitled to an injunction or injunctions to (a) prevent breaches of this Agreement and (b) enforce specifically the performance of the terms and provision of this Agreement, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which the Parties are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

SECTION 10.9. Amendments. No term or provision of this Agreement may be amended except by an instrument in writing signed by both Parties.

SECTION 10.10. Assignment. No Party shall assign this Agreement or any of its rights or benefits under this Agreement, or delegate any of its duties or obligations, except with the prior written consent of the other Party. Any purported assignment or delegation without such consent shall be null and void. This Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

SECTION 10.11. Counterparts.

(a) This Agreement may be executed in any number of counterparts each of which when so executed will be deemed to be an original and when taken together shall constitute the entire and same agreement.

(b) Delivery of an executed signature page to this Agreement by any Party by electronic transmission will be as effective as delivery of a manually executed copy of this Agreement by such Party.

SECTION 10.12. Time of the Essence. With respect to all dates and time periods in this Agreement, time is of the essence.

Subject to the terms of this Agreement, the property, business and affairs of the Company shall be managed by or under the direction of a board of managers of the Company (the “Board of Managers”), which, for the purposes of the Delaware Act, shall be deemed a “manager” (as defined in the Delaware Act), but which shall be subject to the rights, obligations, limitations and duties set forth in this Agreement.

(b) Designation of Managers. Upon the execution and delivery of this Agreement, (i) the Majority Member shall designate three Managers to the Board of Managers (each such Manager, a “Majority Manager”) and (ii) the Minority Member shall designate two Managers to the Board of Managers (each such Manager, a “Minority Manager”). The Managers, designated in accordance with the foregoing, shall constitute the Board of Managers. Each Member shall be entitled to designate one or more alternative Managers who, in the absence or inability to act of a Manager designated by such Member, may attend and vote at meetings of the Board of Managers on behalf of such Member. A Manager may be designated as the alternate Manager for any other Manager.

(d) Resignation of Managers. Any Manager may resign at any time. Such resignation shall be made in writing and shall take effect at the time specified therein, and, if no time is specified, at the time of its receipt by the Board of Managers. The acceptance of a resignation shall not be necessary to make it effective.

(e) Vacancies on the Board of Managers. Other than any removal contemplated by Section 4.01(f)(ii), upon any removal, resignation, death or disability of any Manager, the Member that designated such Manager shall be entitled to designate a replacement in accordance with Section 4.01(b).

To the fullest extent permitted by applicable Law, the Company hereby renounces any interest in any Business Opportunity and any expectancy that any Business Opportunity will be offered to the Company; provided, however, that the Company does not renounce any interest in or expectancy with respect to any Business Opportunity that is offered to any Manager if such Business Opportunity is expressly offered to such Manager in his or her capacity as a Manager.

(i) Subsidiary Boards. To the extent requested by a Member, the Company and the Members shall take all actions necessary to cause the Managers designated by such Member to be designated as members of the board of directors or similar governing body of any of the Company’s Subsidiaries with the same proportionate representation and voting rights of such Managers on such other board of directors or governing body as on the Board of Managers.

Copies of agendas and minutes of all meetings of the Board of Managers shall be distributed to all Managers. Any Manager may participate in any meeting of the Board of Managers by means of a conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

(b) Quorum. At any meeting of the Board of Managers, the presence in person of Managers representing a majority of the entire Board of Managers, including at least one Majority Manager and at least one Minority Manager, shall constitute a quorum for the transaction of business; provided that if a quorum is not present at a first called meeting due to the absence of at least one Majority Manager or at least one Minority Manager, the meeting may be reconvened no earlier than 24 hours after the initial scheduled meeting (with notice of such reconvened meeting being given to each Manager not present at the first called meeting), and at such second called meeting, a quorum shall be deemed present if Managers representing a majority of the entire Board of Managers are present (so long as there is at least one Majority Manager present at such meeting, and regardless of whether any Minority Manager is present at such meeting).

Any action, resolution or decision of the Board of Managers at a meeting of the Board of Managers shall be taken or made if approved by an affirmative vote of Managers representing at least 50% of the voting power of the entire Board of Managers (which must include the affirmative vote of at least one Majority Manager); provided, however, that any Supermajority Approval Action shall require Supermajority Approval in accordance with Section 4.04(b). The collective voting power of the Managers designated by each Member with respect to any action, resolution or decision of the Board of Managers shall equal such Member’s Percentage Interest, as in effect at such time, and such voting power shall be apportioned equally among the Managers designated by such Member. If at any meeting of the Board of Managers there shall be less than a quorum present, a majority of those Managers present shall adjourn the meeting until a quorum is obtained.

(d) Action Without Board of Managers Meeting. Any action, resolution or decision required or permitted to be taken or made at any meeting of the Board of Managers may

be taken or made by written consent in lieu of a meeting if consented to, in writing, by the unanimous consent of the Board of Managers. Any such written consent shall be filed with the minutes of proceedings of the Board of Managers and a copy thereof, together with all materials prepared for, or provided to, any consenting Manager in connection with such action, resolution or decision, shall be promptly provided to each non-consenting Manager, if any.

The Board of Managers shall review the proposed adjustments to the Approved Budget promptly after receipt thereof. If the Board of Managers approves such adjustments by Supermajority Approval, the Approved Budget shall be deemed to be modified to give effect to such adjustments.

this Agreement, then the Board of Managers shall be deemed to not have approved such adjustments.

If such Parent Executives are unable to resolve such Deadlock Event within 21 days after such Deadlock Event is submitted to them for resolution, then (i) unless the Deadlock Event relates to an Identified Action, the Board of Managers shall be deemed to not have approved the relevant action and (ii) if the Deadlock Event relates to an Identified Action, such Deadlock Event shall be resolved in accordance with Section 4.07(c).

The decision of the mediation panel (the “Mediation Panel”) shall be final and binding on each Member and the Company, shall be deemed to have been approved by the Board of Managers in accordance with Section 4.04, and will not be subject to any appeal or proceedings to vacate, except on the grounds set forth in the Federal Arbitration Act, 9 U.S.C. § 1, et seq. The decision of the Mediation Panel may be enforced in any court of competent jurisdiction. The Mediation Panel shall consist of three mediators (each of whom shall have appropriate industry expertise and at least 15 years’ experience in the coal mining industry), one to be appointed by each Member and a third mediator to be chosen by the two Member-appointed mediators. Each mediator shall be independent of each Member and its Affiliates.

The mediation shall be held in St. Louis, Missouri, and the proceeding shall be conducted and concluded as soon as reasonably practicable, based upon the schedule established by the Mediation Panel, but in any event the decision of the Mediation Panel shall be rendered within 15 days following the conclusion of the hearing with respect to such dispute. The Mediation Panel shall act as a limited expert for the specific purposes of resolving the Deadlock Event but may not award

33

Each Member shall bear its own costs and expenses incurred in connection with the mediation, and each Member shall bear 50% of the fees and expenses of the Mediation Panel and the costs of administration of the mediation.

In accordance with the terms of the Implementation Agreement, contemporaneously with the execution of this Agreement, (a) the Peabody Member has made, or caused to be made, a Capital Contribution to the Company as contemplated by the Implementation Agreement in exchange for the issuance by the Company of a Membership Interest to the Peabody Member and the assumption of the Peabody Assumed Liabilities (as defined in the Implementation Agreement) and (b) the Arch Member has made, or caused to be made, a Capital Contribution to the Company as contemplated by the Implementation Agreement in exchange for the issuance by the Company of a Membership

34

Interest to the Arch Member and the assumption of the Arch Assumed Liabilities (as defined in the Implementation Agreement), such that, after giving effect to such transactions, the Members hold the respective Percentage Interests as set forth on Schedule 3.01 as of the date hereof.

Section 5.02 Additional Capital Contributions.

(a) No Member shall be required to make any Capital Contribution to the Company in addition to, or in excess of, such Member’s Initial Capital Contribution pursuant to Section 5.01, other than, and in each case subject to Section 5.02(b), (i) any Capital Contribution approved by the Board of Managers in an amount necessary to fund the Operations in accordance with an Approved Budget or any Permitted Variance, (ii) any Capital Contribution required in connection with an Emergency, (iii) any Capital Contribution approved by the Board of Managers in an amount necessary to fund an Approved Capital Plan and (iv) any other Capital Contribution approved by each Member in writing (each such Capital Contribution referred to in clauses (i), (ii), (iii) and (iv) of this Section 5.02(a), an “Additional Capital Contribution”).

(b) In the event that any Additional Capital Contribution is required to be made in accordance with Section 5.02(a), the Board of Managers shall deliver a written notice of such Additional Capital Contribution (a “Capital Call Notice”) to each Member, and each Member shall contribute in cash its pro rata portion (based on its then-applicable Percentage Interest) of the aggregate amount of such Additional Capital Contribution, or shall cause such portion to be contributed in cash, to the Company on the Capital Call Date, in accordance with this Section 5.02(b) and the Capital Call Notice. The Capital Call Notice shall specify in reasonable detail (i) the Section of this Agreement pursuant to which such Additional Capital Contribution is required to be made, (ii) the aggregate amount of such Additional Capital Contribution, (iii) the amount of such Member’s portion of the aggregate amount of such Additional Capital Contribution, which amount shall be in proportion to such Member’s Percentage Interest, determined as of the date of the Capital Call Notice, (iv) any applicable bank account information and (v) the date on which such Additional Capital Contribution is required to be made (the “Capital Call Date”), which date shall not be earlier than the 15th day following the date of the Capital Call Notice unless otherwise determined by mutual written agreement of the Members.

(c) If any Member fails to timely contribute, in accordance with Section 5.02(b) and the applicable Capital Call Notice, all or any portion (the “Unfunded Amount”) of any Additional Capital Contribution that such Member (the “Defaulting Member”) is required to make in accordance with Section 5.02(a), the Defaulting Member shall be deemed to be in material breach of this Agreement and the Company and the non-Defaulting Member shall be entitled to pursue all remedies available at law or in equity against the Defaulting Member, including the following:

(i) the Company may take all actions, including court proceedings, as the non-Defaulting Member may deem appropriate, to obtain payment by the Defaulting Member of the Unfunded Amount, together with interest at the Default Rate (as in effect on the Capital Call Date) from the Capital Call Date until the date of such contribution, at the cost and expense of the Defaulting Member; or

35

(ii) the non-Defaulting Member may, in its sole discretion, advance all, but not less than all, of the Unfunded Amount to the Company, which advance may, at the option of the non-Defaulting Member, be deemed to be either:

(A) an additional Capital Contribution, in which case the Percentage Interest of each Member shall be adjusted to equal the amount (expressed as a percentage) determined by dividing the total Capital Contributions made by such Member by the total Capital Contributions made by both Members; or

(B) a loan from such non-Defaulting Member to the Company (a “Shortfall Loan”) in the amount so advanced, which Shortfall Loan shall be advanced directly to the Company and shall bear interest at the Default Rate (as in effect on the date that such advance is made) from the date that such advance is made until such Shortfall Loan is repaid in full (and repayment of such Shortfall Loan shall have priority over all Distributions of Distributable Cash or other distributions that would otherwise be payable to the Defaulting Member under Section 7.01 or Section 7.02).

(d) Subject to the approval of each Member, the Members may make loans to the Company, upon such terms and conditions as may be mutually agreed by the Members and the Company, in lieu of making any Additional Capital Contribution. Any such loan by a Member to the Company shall not be considered a Capital Contribution and the making of such loan shall not result in any increase in such Member’s Capital Account.

Section 5.03 Withdrawal of Capital. Except as otherwise provided by this Agreement or the Delaware Act, no Member shall have the right to withdraw, or receive any return of, all or a portion of such Member’s Capital Contributions, nor shall any Member have the right to demand and receive any cash or other property in return for its Capital Contributions. Nothing in this Section 5.03 shall limit the terms of Section 3.06 or Section 11.02.

Section 5.04 Status of Capital Contributions. The Members shall be liable only to make their Capital Contributions pursuant to Section 5.01 and Section 5.02, and no Member shall be required to lend any funds to the Company pursuant to this Agreement. No Member shall have any personal liability for the payment of any Capital Contribution of any other Member.

Section 5.05 Capital Accounts.

(a) The Company shall maintain for each Member an account to be designated its “Capital Account”. The Capital Account of each Initial Member shall be equal to the value of such Member’s Initial Capital Contribution, as set forth on Schedule 5.05, to which shall be added the value of any Additional Capital Contributions made by such Member. The Capital Account of any Additional Member shall be equal to the value of its Initial Capital Contribution (including the value attributed to any non-cash assets provided as Capital Contributions), to which shall be added the value of any Additional Capital Contributions made by such Additional Member. A Member’s Capital Account shall be increased by allocations to such Member of profits of the Company in accordance with Section 6.01. A Member’s Capital Account shall be

36

reduced by (i) the amount of cash distributed to such Member by the Company, (ii) the fair market value of any property distributed to such Member by the Company, net of liabilities secured by the distributed property or subject to which such Member is considered to assume or take the distributed property (in each case, as determined in good faith by the Members in accordance with this Agreement), and (iii) allocations to such Member of losses of the Company in accordance with Section 6.01.

(b) Each Member shall have a single Capital Account that shall reflect its Membership Interest in the Company. If any Member Transfers its Membership Interest in accordance with the terms of this Agreement, the Transferee shall succeed to that portion of the Transferor’s Capital Account which is attributable to such Transferred Membership Interest. The Company shall maintain records to enable separate identification of Capital Contributions and Distributions to the extent related to separate Membership Interests.

(c) The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Regulations Sections 1.704-1(b) and 1.704-2 and shall be interpreted and applied in a manner consistent with such Regulations. In the event that the Board of Managers shall determine that it is prudent to modify the manner in which the Capital Accounts, or any additions thereto or subtractions therefrom, are computed in order to comply with such Regulations, which for the avoidance of doubt includes any modifications pursuant to Section 6.04(b), the Board of Managers may make such modification, provided if such modification is likely to have a material effect on the amounts distributable to any Member pursuant to Article VII or Article XI hereof, such modification shall require Supermajority Approval.

ARTICLE VI

Allocations of Profit and Loss; Tax Matters

Section 6.01 Allocation of Net Profits and Net Losses. Subject to the other provisions of this Article VI, for purposes of adjusting the Capital Accounts of the Members, the Net Profits, Net Losses and, to the extent necessary, individual items of income, gain, loss, credit and deduction, for any fiscal year shall be allocated among the Members in a manner such that the Adjusted Capital Account of each Member, immediately after making such allocation is, as nearly as possible, equal (proportionately) to the distributions that would be made to such Member pursuant to Section 11.02 if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Gross Asset Value, all Company liabilities were satisfied (limited with respect to each Nonrecourse Liability to the Gross Asset Value of the asset securing such liability), and the net assets of the Company were distributed in accordance with Section 11.02 to the Members immediately after making such allocation.

Section 6.02 Special Allocations. Notwithstanding the foregoing provisions of this Article VI, the following special allocations shall be made in the following order of priority:

(a) Minimum Gain Chargeback. If there is a net decrease in Company Minimum Gain during any Company taxable year, then each Member shall be allocated items of Company income and gain for such taxable year (and, if necessary, for subsequent years) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, determined in

37

accordance with Regulations Section 1.704-2(g)(2). This Section 6.02(a) is intended to comply with the minimum gain chargeback requirement of Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

(b) Member Minimum Gain Chargeback. If there is a net decrease in Member Minimum Gain attributable to a Member Nonrecourse Debt during any Company taxable year, then each Member who has a share of the Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain for such taxable year (and, if necessary, for subsequent years) in an amount equal to such Member’s share of the net decrease in Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of Regulations Section 1.704-2(i)(4). This Section 6.02(b) is intended to comply with the Member Nonrecourse Debt minimum gain chargeback requirement of Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c) Qualified Income Offset. If any Member unexpectedly receives an adjustment, allocation, or distribution of the type contemplated by Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), then items of income and gain shall be allocated to all such Members (in proportion to the amounts of their respective deficit Adjusted Capital Accounts) in an amount and manner sufficient to eliminate the deficit balance in the Adjusted Capital Account of such Member as quickly as possible. It is intended that this Section 6.02(c) qualify and be construed as a “qualified income offset” within the meaning of Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d) Limitation on Allocation of Net Loss. If the allocation of Net Loss (or items of loss or deduction) to a Member as provided in Section 6.01 hereof would create or increase an Adjusted Capital Account deficit, then there shall be allocated to such Member only that amount of Net Loss (or items of loss or deduction) as will not create or increase an Adjusted Capital Account deficit. The Net Loss (or items of loss or deduction) that would, absent the application of the preceding sentence, otherwise be allocated to such Member shall be allocated to the other Members in proportion to their relative Percentage Interests, subject to the limitations of this Section 6.02(d).

(e) Certain Additional Adjustments. To the extent that an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Regulations Section 1.704-1(b)(2)(iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Member in complete liquidation of its Membership Interest, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such gain or loss shall be specially allocated to the Members in accordance with their Membership Interests in the Company in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Members to whom such distribution was made in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

(f) Nonrecourse Deductions. The Nonrecourse Deductions for each Company taxable year shall be allocated to the Members in proportion to their relative Percentage Interests.

38

(g) Member Nonrecourse Deductions. The Member Nonrecourse Deductions shall be allocated each year to the Member that bears the economic risk of loss (within the meaning of Regulations Section 1.752-2) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable.

(h) Curative Allocations. The allocations set forth in Section 6.02(a) through Section 6.02(g) hereof (the “Regulatory Allocations”) are intended to comply with certain requirements of Regulations Sections 1.704-1(b) and 1.704-2(i). Notwithstanding the provisions of Section 6.01, the Regulatory Allocations shall be taken into account in allocating other items of income, gain, loss and deduction among the Members so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Member shall be equal to the net amount that would have been allocated to each such Member if the Regulatory Allocations had not occurred.

Section 6.03 Tax Allocations.

(a) Except as provided in Section 6.03(b) hereof, for income tax purposes under the Code and the Regulations each Company item of income, gain, loss, deduction and credit shall be allocated among the Members as its correlative item of “book” income, gain, loss, deduction or credit is allocated pursuant to this Article VI.

(b) Tax items with respect to any Company asset that is contributed to the Company with a Gross Asset Value that varies from its basis in the hands of the contributing Member immediately preceding the date of contribution shall be allocated among the Members for income tax purposes pursuant to Regulations promulgated under Code Section 704(c) so as to take into account such variation. The Company shall account for such variation using any method approved under Code Section 704(c) and the applicable Regulations as chosen by the Board of Managers. If the Gross Asset Value of any Company asset is adjusted pursuant to the definition of “Gross Asset Value” herein, subsequent allocations of income, gain, loss, deduction and credit with respect to such Company asset shall take account of any variation between the adjusted basis of such Company asset for federal income tax purposes and its Gross Asset Value in a manner consistent with Code Section 704(c) and the applicable Regulations using any method approved under Code Section 704(c) and the applicable Regulations as chosen by the Board of Managers. Any (i) recapture of Depreciation or any other item of deduction shall be allocated, in accordance with Regulations Section 1.1245-1(e), to the Members that received the benefit of such deductions (taking into account the effect of remedial allocations), and (ii) recapture of tax credits shall be allocated to the Members in accordance with applicable Law. Tax credits of the Company shall be allocated among the Members as provided in Regulations Sections 1.704-(b)(4)(ii) and 1.704-1(b)(4)(viii). If, as a result of an exercise of a noncompensatory option to acquire an interest in the Company, a Capital Account reallocation is required under Regulations Section 1.704-1(b)(2)(iv)(s)(3), the Company shall make corrective allocations pursuant to Regulations Section 1.704-1(b)(4)(x).

(c) Allocations pursuant to Section 6.03(b) are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Net Profits, Net Losses and any other items or distributions pursuant to any provision of this Agreement.

39

Section 6.04 Other Tax Provisions.

(a) For any fiscal year or other period during which any part of a Membership Interest in the Company is transferred between the Members or to another person, the portion of the Net Profits, Net Losses and other items of income, gain, loss, deduction and credit that are allocable with respect to such part of a Membership Interest in the Company shall be apportioned between the transferor and the transferee using any method allowed pursuant to Code Section 706 and the applicable Regulations as chosen by the Board of Managers.

(b) In the event that the Code or any Regulations require allocations of items of income, gain, loss, deduction or credit different from those set forth in this Article VI, the Board of Managers is hereby authorized to make new allocations in reliance on the Code and such Regulations, and no such new allocation shall give rise to any claim or cause of action by any Member.

(c) For purposes of determining a Member’s proportional share of the Company’s “excess nonrecourse liabilities” within the meaning of Regulations Section 1.752-3(a)(3), each Member’s interest in Net Profits shall be such Member’s Percentage Interest.

(d) In accordance with Regulations Section 1.704-1(b)(4)(iii), excess percentage depletion deductions with respect to depletable property shall be allocated to the Members in accordance with the allocation of gross income from the property from which such deductions are derived. The term “excess percentage depletion” shall mean the excess, if any, of deductions for percentage depletion as determined for tax purposes over the Gross Asset Value of the depletable property.

(e) The Members acknowledge and are aware of the income tax consequences of the allocations made by this Article VI and hereby agree to be bound by the provisions of this Article VI in reporting their shares of Net Profits, Net Losses and other items of income, gain, loss, deduction and credit for federal, state and local income tax purposes.

Section 6.05 Partnership Audit Matters. The Operator shall serve as the “partnership representative” within the meaning of Code Section 6223(a) (any person so designated as the partnership representative, the “Tax Representative”). If required by applicable Law, including Regulations Section  ###-###-####-1(b)(3), the Tax Representative shall designate an individual Person (the “Designated Individual”) to act on behalf of the Tax Representative in applicable tax matters and applicable proceedings with tax authorities. The Tax Representative and the Designated Individual shall act on behalf of the Company under Subchapter C of Section 63 of the Code (relating to partnership audit proceedings) and in any tax proceedings brought by other taxing authorities, and the Company and all Members shall be bound by the actions taken by the Tax Representative or the Designated Individual in such capacity. The Members, the Company, the Tax Representative and the Designated Individual agree to make, in the manner prescribed by the Regulations, the election pursuant to Code Section 6221(b) (the “Opt-Out Election”), for every taxable year of the Company for which the Opt-Out Election is available. In the event that the Opt-Out Election is not available, following a reasonable period of time to permit the Members to use commercially reasonable efforts to cooperate in determining the method for paying any “imputed underpayment” described in Code Section 6225(c), any Member may direct, in its sole discretion, the Tax Representative and the Designated Individual

40

to make, on a timely basis, the election provided by Code Section 6226(a) (the “Push-Out Election”) to treat a “partnership adjustment” as an adjustment to be taken into account by each Member in accordance with Code Section 6226(b), and if so directed, the Tax Representative or the Designated Individual shall make the Push-Out Election; provided that, notwithstanding Schedule 4.04(b), the making of the Push-Out Election and any actions taken by the Tax Representative or the Designated Individual in connection with making the Push-Out Election shall not require Supermajority Approval. If the Push-Out Election is made, the Company shall furnish to each Member for the year under audit a statement reflecting the Member’s share of the adjusted items as determined in the notice of final partnership adjustment, and each such Member shall take such adjustment into account as required under Code Section 6226(b) and shall be liable for any related interest, penalty, addition to tax, or additional amounts. With respect to any imputed underpayment to which Code Section 6225 applies, (a) the Tax Representative and the Designated Individual shall request that the IRS approve any modifications available under Code Section 6225(c) that would reduce any imputed underpayment, the Company’s allocable share, if any, of an imputed underpayment from any lower-tier tax partnership, and interest, penalty, addition to tax, or additional amount that could be assessed and collected from the Company under Chapter 63 of the Code, including modifications arising as a result of a Member filing an amended return pursuant to clause (c) of this Section 6.05 (“Company Level Taxes”), (b) the Company, the Tax Representative and the Designated Individual shall use commercially reasonable efforts to ensure that any imputed underpayment is borne by the Members (or former Members) to whom the underpayment is attributable and to cause any reduction attributable to the status of a Member to be allocated to such Member (taking into account the amendments described in clause (c) of this Section 6.05) and (c) any Member may file an amended U.S. federal income tax return (as described in Code Section 6225(c)(2)) that takes into account all adjustments to the reviewed year of the Company properly allocable to such Member and pay any tax due with such return; provided, however, that no Member shall be required to file an amended U.S. federal income tax return without the consent of such Member; provided further that notwithstanding Schedule 4.04(b), any actions taken by the Tax Representative or the Designated Individual in connection with the filing of such amended tax return shall not require Supermajority Approval. Each Member agrees to indemnify and hold harmless the Company, the Tax Representative and the Designated Individual from and against any liability with respect to such Member’s proportionate share (taking into account any reductions in accordance with clause (c) of the immediately preceding sentence and the effect of the Push-Out Election, if made) of any Company Level Taxes in connection with a Company-level tax audit of a taxable period during which such Member was a Member of the Company, regardless of whether such Member is a member of the Company in the year in which such Company Level Tax is actually imposed on the Company or becomes payable by the Company as a result of such audit.

Section 6.06 Tax Returns. Except as otherwise provided for in this Agreement, including clause (ix) of Item 19 of Schedule 4.04(b), the Tax Representative shall, in any reasonable manner, prepare or cause to be prepared and file or cause to be filed for each Taxable Year of the Company all tax and information returns that the Company is required to file. Each Member shall, upon request of the Company, supply any information necessary for the Company to prepare such tax returns. At least 75 days prior to the due date (taking into consideration timely filed extensions) of any income tax return, and at least 30 days prior to the due date (taking into consideration timely filed extensions) of any Wyoming ad valorem and severance

41

tax return or Wyoming personal property tax return (the “Wyoming Returns”), the Tax Representative shall provide to each Member a draft of such tax return, together with all supporting workpapers necessary to complete a review. Each Member shall provide comments on any draft income tax return at least 45 days prior to the due date of any income tax return (taking into consideration timely filed extensions) and at least 15 days prior to the due date of any Wyoming Return (and, in the case of any income tax return, each Member shall receive a copy of the final returns no later than August 31 of each calendar year). For each Taxable Year of the Company, the Tax Representative shall cause the Members to be provided, on a timely basis, with information needed by them to file their own tax returns by reason of their interest in the Company, including the applicable Schedule K-1 to the Company’s U.S. federal partnership tax return for such Taxable Year. Notwithstanding anything in this Agreement to the contrary, the Tax Representative shall be authorized to engage a Third Party to assist it in performing its obligations under this Article VI, and the costs and expenses of the Tax Representative incurred in connection with its obligations shall be reimbursed by the Company. Each Member shall prepare and file its tax returns in a manner consistent with the positions taken by the Company in its tax returns.

Section 6.07 Tax Elections.

(a) The Company shall make the following elections for all partnership income tax returns:

(i) to elect the calendar year as the Company’s fiscal year if permitted by applicable law;

(ii) to elect the accrual method of accounting;

(iii) to elect to treat all organizational and start up costs of the Company as deferred expenses amortizable over 180 months under Sections 195 and 709 of the Code;

(iv) to make an election to adjust the basis of the Company property with respect to a Member under Code Section 754 at the request of the Member;

(v) to annually elect out of bonus depreciation for purposes of Code Section 168(k); and

(vi) to include cost depletion and percentage depletion as a component of costs of goods sold in accordance with Treasury Regulations Section 1.263A-1(e)(3)(ii)(J), Code Section 471 and the Treasury Regulations thereunder.

(b) The Board of Managers, in its reasonable discretion, may cause the Company to make or decline to make, or to revoke or seek to revoke, any other election which the Company may make under the tax laws. The Members agree to provide information reasonably requested by the Board of Managers in order to ensure compliance with the requirements of these rules.

42

Section 6.08 Taxation as Partnership. The Company shall be treated as a partnership for U.S. federal, state, local and foreign tax purposes and the Members agree to take all reasonable actions, including the amendment hereof (so long as such amendment does not materially adversely affect any Member or its Affiliates) and the execution of other documents, as may reasonably be required to qualify for and receive such treatment and further agree not to take any position or make any election, in a tax return or otherwise, inconsistent therewith.

Section 6.09 Withholding.

(a) The Tax Representative, with Supermajority Approval by the Board of Managers, may cause the Company to withhold from payments or distributions to a Member or payments received by the Company to the extent allocable to any Member and to pay over to any Governmental Authority on behalf of such Member any amount required to be so withheld or paid pursuant to the Code or any other federal, foreign, state or local Law, and any amount so withheld or otherwise paid with respect to any such payment, distribution or allocation shall be treated for all purposes of this Agreement as paid, distributed or allocated, as applicable, to the applicable Member. Each Member hereby agrees to indemnify and hold harmless the Company, the Tax Representative, the other Members and the Board of Managers from and against any liability for taxes (including penalties, interest or other additions to tax) required to be withheld from distributions to or payments with respect to such Member.

(b) Upon the Company’s request, each Member shall promptly provide to the Company a duly completed and executed IRS Form W-9 or the appropriate IRS Form W-8 and such other information as may be reasonably requested by the Company (including without limitation an affidavit of non-foreign status pursuant to Code Section 1446(f)(2)) in order for the Company to accurately determine its withholding obligation, if any. A Member making a Transfer permitted by this Agreement shall (i) at least ten Business Days prior to the consummation of such Transfer, deliver to the Company an affidavit of non-foreign status with respect to such Member that satisfies the requirements of Code Section 1446(f)(2), or (ii) no more than 15 Business Days following such Transfer, provide to the Company proof that the Transferee has properly withheld and remitted to the IRS the amount of tax required to be withheld upon the Transfer by Code Section 1446(f).

Section 7.03 Limitations on Distributions. Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make any Distribution if such Distribution would violate Section 18-607 of the Delaware Act or other applicable Law, or the terms of any credit facility or any financing arrangement of the Company or any of its Subsidiaries, but shall instead make such Distribution as soon as practicable after such time, if any, as of which the making of such Distribution shall have ceased to cause any such violation.

ARTICLE VIII

ARTICLE IX

Liability, Exculpation and Indemnification

Section 9.01 Liability. Except as otherwise provided by the Delaware Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Member or other Covered Person shall be obligated personally for any such debt, obligation or liability of the Company by reason of being a Member or other Covered Person. Except as expressly provided herein, no Member, in its capacity as such, shall have liability to the Company or any other Member hereunder. No Member or former Member shall be liable for the Capital Contributions of, the return of the Capital Contributions of, or any Distribution to, any other Member.

Section 9.02 Exculpation.

(a) No Covered Person shall be liable to the Company or any other Covered Person for any costs, expenses, damages or other liability incurred by reason of any act or omission (in relation to the Company or this Agreement) performed or omitted by such Covered Person in good faith on behalf of the Company; provided that a Covered Person shall be liable for any such costs, expenses, damages or other liability resulting from (i) any gross negligence, fraud or willful misconduct of such Covered Person or (ii) any such act or omission that such Covered Person does not reasonably believe to be within the scope of authority conferred on such Covered Person by this Agreement. This Section 9.02 is not intended to alter or expand the

46

rights or obligations that a Covered Person may have under any Applicable Agreement with the Company or its Subsidiaries.

(b) A Covered Person shall be fully protected in relying in good faith upon the records of the Company and upon such information, opinions, reports or statements presented to the Company by any Person as to matters the Covered Person reasonably believes are within such other Person’s professional or expert competence, including information, opinions, reports or statements as to the value and amount of the assets, liabilities or any other facts pertinent to the existence and amount of assets from which Distributions to Members might properly be paid.

Section 9.03 Fiduciary Duty.

(a) To the fullest extent permitted by applicable Law (including Section 18-1101 of the Delaware Act), no Member, Operator or Affiliate of any of the foregoing acting under this Agreement shall have any fiduciary or similar duty, at law or in equity, or any liability relating thereto, to the Company or any other Member, Operator or Affiliate of any of the foregoing, with respect to or in connection with the Company or the Company’s business or affairs. The provisions of this Agreement, to the extent that they restrict the duties and liabilities of a Member, Operator or Affiliate of any of the foregoing otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of such Member, Operator or Affiliate of any of the foregoing.

(b) Without limitation of Section 4.01(h), each Manager shall have the same fiduciary duties as a member of a board of directors of a Delaware corporation (assuming such corporation had in its certificate of incorporation a provision eliminating the liabilities of directors as provided in Section 102(b)(7) of the Delaware General Corporation Law); provided, however, that each Manager shall be permitted to take into account the interests of the Member that designated such Manager in the course of discharging such Manager’s fiduciary duties.

Section 9.04 Indemnification. To the fullest extent permitted by applicable Law, the Company shall indemnify each Covered Person for any cost, expense, damage or other liability incurred by such Covered Person by reason of (a) (i) any Assumed Liabilities (as defined in the Implementation Agreement) or (ii) any Outstanding Financial Assurances (as defined in the Implementation Agreement), including all claims or premiums payable thereunder and all direct and indirect costs incurred in connection with furnishing and maintaining any collateral (including cash collateral and letters of credit) required thereunder (except as required pursuant to Section 3.09), (b) any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of authority conferred on such Covered Person by this Agreement or (c) any Proceeding seeking any such amount or otherwise relating to any such act or omission or the fact that such Person is or was a Covered Person, except that no Covered Person shall be entitled to be indemnified with respect to any cost, expense, damage or other liability to the extent incurred by such Covered Person by reason of (i) the gross negligence, fraud or willful misconduct of such Covered Person, (ii) any such act or omission that such Covered Person does not reasonably believe to be within the scope of authority conferred on such Covered Person by this Agreement or (iii) any Proceeding initiated by such Covered Person (other than a Proceeding to enforce such Covered Person’s rights under this Section 9.04); provided that any indemnity under this

47

Section 9.04 shall be provided out of and to the extent of Company assets only, and no other Covered Person shall have any personal liability on account thereof. The Company hereby agrees that it is the indemnitor of first resort (i.e., its indemnification and advancement of expenses obligations to any Covered Person under this Agreement are primary and any separate obligation that any Member or Affiliate thereof may have to provide indemnification or advancement of expenses for the same costs, expenses, damages or other liabilities incurred by such Covered Person is secondary), and if any Member or Affiliate thereof pays or causes to be paid, for any reason, any amounts otherwise indemnifiable hereunder or under any other indemnification agreement (whether pursuant to any Contract, any organizational documents or otherwise) with any Covered Person, then (x) such Member or Affiliate thereof shall be fully subrogated to all rights of such Covered Person with respect to such payment and (y) the Company shall reimburse such Member or Affiliate thereof for the payments actually made. This Section 9.04 is not intended to alter or expand the rights or obligations that a Covered Person may have under any Applicable Agreement with the Company or its Subsidiaries.

Section 9.05 Expenses. To the fullest extent permitted by applicable Law, reasonable expenses (including reasonable legal fees) incurred by a Covered Person in defending any Proceeding subject to indemnification pursuant to Section 9.04 shall, from time to time, be advanced by the Company to the Covered Person prior to the final disposition of such Proceeding upon receipt by the Company of an undertaking by or on behalf of the Covered Person to repay such amount if it shall be determined that the Covered Person is not entitled to indemnification with respect thereto pursuant to Section 9.04.

Section 9.06 Insurance. The Company may purchase and maintain insurance, to the extent and in such amounts as the Board of Managers by resolution shall deem reasonable or appropriate, on behalf of Covered Persons and such other Persons as the Board of Managers by resolution shall determine, against any liability that may be asserted against or expenses that may be incurred by any such Person in connection with the activities of the Company or any indemnities provided by the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

Section 9.07 Other Procedures. The Members and the Company may enter into indemnity contracts with Covered Persons and such other Persons as the Board of Managers shall determine and adopt written procedures pursuant to which arrangements are made for the advancement of expenses and the funding of obligations under Section 9.04 and Section 9.05 and containing such other procedures regarding indemnification as are consistent with the provisions of this Agreement.

ARTICLE X

Transfer of Membership Interests; Redemption

Section 10.01 Transfer of Membership Interests Generally. No Member may, directly or indirectly, Transfer or permit any Transfer of all or any portion of the Membership Interest directly or indirectly owned by such Member to any Person, unless (a) such Transfer is specifically permitted by, and consummated in accordance with, this Article X, (b) in the event such Transfer is not to another Member, the Transferee shall execute and deliver to the Company an Adoption Agreement and (c) either (i) such Transfer is pursuant to an effective registration

48

statement under the Securities Act of 1933, as amended (the “Securities Act”), and has been registered under all applicable state securities or “blue sky” Laws or (ii) no such registration is required because of the availability of an exemption from registration under the Securities Act and any applicable state securities or “blue sky” Laws. Any Transferee of a Member’s Membership Interest shall be bound by the terms and provisions of this Agreement that apply to such Member specifically, in addition to terms and provisions of this Agreement that generally apply to any Member, and such Transferee shall assume or shall otherwise satisfy or discharge any obligations and commitments of such Member and its Affiliates. All rights that are applicable to a specific Member hereunder (including the right to designate Managers pursuant to Section 4.01(b)) shall be Transferable in connection with a valid Transfer hereunder. To the fullest extent permitted by applicable Law, any purported Transfer of any Membership Interest in breach of this Agreement shall be null and void ab initio, and neither the Company nor the Members shall recognize the same. Any Member who Transfers or attempts to Transfer any Membership Interest except in compliance herewith shall be liable to, and shall indemnify and hold harmless, the Company and the other Members for all costs, expenses, damages and other liabilities resulting therefrom.

Section 10.02 Permitted Transfers. Subject to the restrictions set forth in this Article X:

(a) each Member may Transfer all, but not less than all, of its Membership Interest to a Wholly Owned Affiliate of such Member that is organized under the Laws of any state of the United States of America (an “Affiliate Transferee”), subject to Section 6.03(c); provided, however, that (i) such Transferor shall remain responsible for the obligations and commitments owed to the Company, with respect to such Membership Interest, on or before the date of such Transfer, (ii) if the Parent or any other Affiliate of such Transferor has provided a Guarantee to the Company in respect of any of such Transferor’s agreements, covenants or other obligations owed to the Company or the Members, such Guarantee shall remain in full force and effect and such Parent or other Affiliate shall remain responsible for the agreements, covenants or other obligations of such Transferor and such Affiliate Transferee owed to the Company or the Members thereunder, and (iii) such Transfer shall not subject the Company to, and shall not be reasonably likely to subject the Company to, any regulatory or tax obligations (other than immaterial tax reporting obligations) that would not otherwise be applicable to the Company if such Transfer were not to occur. In the event that subsequent to any such Transfer, the Company becomes, or is reasonably likely to become, subject to any such regulatory or tax obligations (other than immaterial tax reporting obligations) as a result of such Transfer or the identity of such Affiliate Transferee, then such Transferor (or such initial Transferor, as applicable) shall cause such Affiliate Transferee to Transfer its Membership Interest back to such Transferor and, pending such Transfer back, all rights of the Affiliate Transferee (and any Manager appointed by such Affiliate Transferee) under this Agreement (but not such Affiliate Transferee’s obligations) shall be immediately suspended; and

(b) at any time after the first anniversary of the date hereof, each Member may Transfer all, but not less than all, of its Membership Interest to any Third Party in accordance with Section 10.01, Section 10.03, Section 10.05 and Section 10.06.
