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 thisclause (B), a “Transaction Modification”), in each case as may be necessary to cause the conditions set forth inSections 7.1(a),7.1(b) and7.1(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 thisSection 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 netafter-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.

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 thisSection 6.4(f);provided,however, that any materials furnished pursuant to thisSection 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

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.

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 inSection 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 inSection 7.3(e) on the Closing Date;provided,however, that nothing in thisSection 6.4(g) shall require Arch to purchase or divest any assets.

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 inArticle 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 allNon-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 suchNon-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 suchNon-Assignable Asset, (B) shall have dominion and control over suchNon-Assignable Asset and (C) shall assume the legal and economic burden, obligations and Liabilities with respect to suchNon-Assignable Asset and shall indemnify, defend and hold harmless the Person that is party to or otherwise holds suchNon-Assignable Asset therefor. The Person that is party to or otherwise holds any suchNon-Assignable Asset shall hold suchNon-Assignable Asset in trust for the sole benefit and on behalf of the applicable JV Entity and shall, as soon as

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

(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.

(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;

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

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 thisSection 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 thisSection 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

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

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 anyco-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 Procedure2004-53, 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 thisSection 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 thisSection 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

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 thePre-Closing Reorganizations and (b) keep the other Party reasonably informed on a timely basis with respect to all material activity concerning the status of thePre-Closing Reorganizations. The agreements and instruments to effectuate thePre-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;providedfurther 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

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 andnon-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

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 thisSection 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 thisSection 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 abona fidewritten 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.

(b) During the30-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 includesnon-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 thisSection 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 anon-exclusive, royalty-free, perpetual, irrevocable, fullypaid-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 Arch and its Affiliates, on the one hand, and the JV Entities, on the other hand, may modify or improve the Arch Retained IP

licensed pursuant to thisSection 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 thisSection 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 suchsix-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 anyPre-Closing Tax Period (the “PeabodyPreparedReturns”), 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 anyPre-Closing Tax Period (the “ArchPreparedReturns”). 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

to thisSection 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 thisSection 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 toSection 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 aPre-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

Entities shall retain all books and records with respect toPre-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 underSection 8.2 or that would give rise to aPre-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 underSection 8.3 or that would give rise to aPre-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 underSection 8.2 or that would give rise to aPre-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 underSection 8.3 or that would give rise to aPre-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 thisSection 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 toSection 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

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

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 toSection 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 inSection 8.2(a) andSection 8.3(a), respectively, shall not exceed the Indemnity Cap Amount.

(d) Notwithstanding anything in this Agreement to the contrary, the limitations set forth inSections 8.5(b) and8.5(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.

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 underSection 8.2 andSection 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

Claim under thisArticle 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 bySection 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 such45-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 toSection 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.

(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

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

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 ofSection 8.2,8.3 or8.4, 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).

SECTION 8.11.Exclusive Remedy. Except as permitted bySection 3.5,6.8,6.18,6.19 or10.8, from and after the Closing, indemnification pursuant to thisArticle 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 thisArticle 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.

(a) This Agreement, and anynon-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 inSection 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

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 THISSECTION 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 inArticle VIII or thisSection 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 thisSection 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.

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

accordingly agreed that, prior to the termination of this Agreement pursuant toArticle 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.

If any Deadlock Event is not resolved within 30 days after the delivery of a Deadlock Notice, the Members shall escalate such Deadlock Event to the chief executive officers of each Member’s Parent (the “Parent Executives”) for resolution, and such Parent Executives shall consult and negotiate with each other in good faith (including at least one meeting in person, at a mutually acceptable time and place) to attempt to resolve such Deadlock Event within 21 days of such escalation. 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 withSection 4.07(c).

(c) In the event that any Deadlock Event relating to an Identified Action has not been resolved within 12 months after delivery of a Deadlock Notice, either Member may elect to submit the dispute for resolution by binding mediation administered by the American Arbitration Association (the “AAA”) pursuant to its Commercial Mediation Procedures then in existence (the “Rules”) and in accordance with thisSection 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 withSection 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,etseq. 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. If either Member fails to appoint a mediator or the two Member-appointed mediators fail to appoint the third within the time periods described below, then the appointments shall be made by the AAA pursuant to the Rules. 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

damages, interest or penalties to either Member with respect to any Deadlock Event. 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 the event of an Emergency, notwithstanding anything to the contrary in this Agreement, the Operator is authorized to (a) make all notifications required under applicable Law to the appropriate Governmental Authorities, (b) implement Emergency response and mitigation measures as are required by applicable Law or are otherwise deemed necessary or advisable by the Board of Managers or the Operator to respond to or mitigate the Emergency and (c) commence any required remediation, maintenance or repair work necessary (i) for the assets and properties of the Company to operate safely and in compliance with applicable Law, (ii) for the Company to be in compliance with all applicable Laws and (iii) to otherwise mitigate damage resulting from the Emergency. The Operator shall as promptly as reasonably practicable notify all the Managers in writing upon the occurrence of any Emergency and shall keep the Managers reasonably informed as to the status thereof.

Section 4.09Capital Projects.

(a) The Operator may from time to time submit to the Board of Managers and the Members a proposal for a capital project, including any expansion of capacity of the Company’s existing assets or development of an undeveloped mineral deposit, that is not reflected in the then-current Approved Budget (a “Proposed Capital Project”). Such proposal shall include (i) the projected revenue, capital costs and operating costs for such Proposed Capital Project, (ii) the proposed Additional Capital Contributions to be made by the Members to fund such Proposed Capital Project, (iii) any external financing proposed to be pursued in connection with such Proposed Capital Project and (iv) any other information which the Operator deems relevant to the consideration of such Proposed Capital Project.

(ii) thenon-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 thenon-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 suchnon-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 underSection 7.01 orSection 7.02).

Section 5.05CapitalAccounts.

(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 onSchedule 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 anynon-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 withSection 6.01. A Member’s Capital Account shall be

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 withSection 6.01.

(b) Each Member shall have a single Capital Account that shall reflect its Membership Interest in the Company.

ARTICLE VI

Allocations of Profit and Loss; Tax Matters

Section 6.01Allocation of Net Profits and Net Losses. Subject to the other provisions of thisArticle 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 toSection 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 withSection 11.02 to the Members immediately after making such allocation.

Section 6.02SpecialAllocations. Notwithstanding the foregoing provisions of thisArticle 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

accordance with RegulationsSection 1.704-2(g)(2). ThisSection 6.02(a) is intended to comply with the minimum gain chargeback requirement of RegulationsSection 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 RegulationsSection 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 RegulationsSection 1.704-2(i)(4). ThisSection 6.02(b) is intended to comply with the Member Nonrecourse Debt minimum gain chargeback requirement of RegulationsSection 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 RegulationsSection 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 thisSection 6.02(c) qualify and be construed as a “qualified income offset” within the meaning of RegulationsSection 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 inSection 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 thisSection 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 RegulationsSection 1.704-1(b)(2)(iv)(m)(2) or RegulationsSection 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 RegulationsSection 1.704-1(b)(2)(iv)(m)(2) applies, or to the Members to whom such distribution was made in the event that RegulationsSection 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.

(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 RegulationsSection 1.752-2) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable.

(h)Curative Allocations. The allocations set forth inSection 6.02(a) throughSection 6.02(g) hereof (the “Regulatory Allocations”) are intended to comply with certain requirements of Regulations Sections1.704-1(b) and1.704-2(i). Notwithstanding the provisions ofSection 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 6.03Tax Allocations.

(a) Except as provided inSection 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 thisArticle 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 RegulationsSection 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 RegulationsSections 1.704-(b)(4)(ii) and1.704-1(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 RegulationsSection 1.704-1(b)(2)(iv)(s)(3), the Company shall make corrective allocations pursuant to RegulationsSection 1.704-1(b)(4)(x).

(c) Allocations pursuant toSection 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.

Section 6.04Other 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 thisArticle 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 RegulationsSection 1.752-3(a)(3), each Member’s interest in Net Profits shall be such Member’s Percentage Interest.

(d) In accordance with RegulationsSection 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 thisArticle VI and hereby agree to be bound by the provisions of thisArticle 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 6.05Partnership 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 RegulationsSection 301.6223-1(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 theOpt-Out Election is available. In the event that theOpt-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

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 thePush-Out Election;provided that, notwithstandingSchedule 4.04(b), the making of thePush-Out Election and any actions taken by the Tax Representative or the Designated Individual in connection with making thePush-Out Election shall not require Supermajority Approval. If thePush-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 toclause (c) of thisSection 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 inclause (c) of thisSection 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 notwithstandingSchedule 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 withclause (c) of the immediately preceding sentence and the effect of thePush-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 6.06TaxReturns. Except as otherwise provided for in this Agreement, includingclause (ix) of Item 19 ofSchedule 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

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).

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 thisArticle 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 6.09Withholding.

(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.

Transfer of Membership Interests; Redemption

Section 10.01Transfer 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, thisArticle 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

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 toSection 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 10.02PermittedTransfers. Subject to the restrictions set forth in thisArticle 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 toSection 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 withSection 10.01,Section 10.03,Section 10.05 andSection 10.06.

Section 10.03NoPublicly Traded Partnership. Notwithstanding anything in this Agreement to the contrary, no Transfer of any Membership Interest may be made if, in the reasonable determination of the Board of Managers, such Transfer would result in the Company being treated as a “publicly traded partnership” within the meaning of Code Section 7704(b).

Section 10.04Encumbrances. The pledge or granting of a Permitted Encumbrance against any Member’s Membership Interest shall not be deemed to be a Transfer subject to the restrictions of thisArticle X. Any foreclosure or exercise of other secured party remedies with respect to any such Permitted Encumbrance shall be deemed to be a Transfer subject to the restrictions of thisArticle X.

Section 10.05Right ofFirst Refusal.

(a) In the event that any Member (the “Selling Member”) receives from any prospective Transferee other than any Member and other than any Person that qualifies as an Affiliate Transferee of the Selling Member (such prospective Transferee, the “Offeror”) a bona fide written offer (the “Offer”) to directly or indirectly purchase all, but not less than all, of the Membership Interest owned by the Selling Member (such Membership Interest, the “Offered Interest”) in any transaction or series of related transactions on terms that the Selling Member is willing to accept, the Selling Member shall, as promptly as practicable but in no event later than five Business Days after the Selling Member’s receipt of the Offer, provide written notice thereof (the “Offer Notice”) to the Company and the Member that is not the Selling Member (the “Non-Selling Member”). The Offer Notice shall set forth (i) the aggregate Percentage Interest represented by the Offered Interest (which shall be all of the Percentage Interest owned by the Selling Member), (ii) the identity of the Offeror, (iii) the type and amount of consideration proposed to be paid for the Offered Interest (including a description of any proposednon-cash consideration), (iv) the terms of the Offeror’s financing, if any, and (v) any other material terms or conditions of the Offer (collectively, the “Offer Terms”) 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;provided that, in the event that the Offer is part of a broader transaction involving the Selling Member or an Affiliate thereof, the determination of the portion of the consideration for such transaction constituting the proposed purchase price for the Offered Interest for the purposes of a Matching Offer shall be made by an Appraiser selected by the Selling Member and reasonably acceptable to theNon-Selling Member.

(b) TheNon-Selling Member may, within 45 days after the date of the Offer Notice (5:00 p.m. (New York City time) on such 45th day, the “ROFR Deadline”), irrevocably offer to purchase all, but not less than all, the Offered Interest pursuant to and in accordance withSection 10.05(c) by providing written notice of such offer to purchase the Offered Interest (a “ROFR Election Notice”) to the Company and the Selling Member prior to the ROFR Deadline. Any such ROFR Election Notice shall contain a bona fide, binding, fully financed offer on behalf of theNon-Selling Member on the Offer Terms, it being agreed that if any of the Offer Terms includenon-cash consideration, theNon-Selling Member may substitute cash of equivalent value (any such offer made pursuant to and in accordance with thisSection 10.05(b), a “Matching Offer”).

(c) If a valid and timely Matching Offer is made, the Selling Member shall be entitled, in its sole discretion, either to continue to hold the Offered Interest or to Transfer all, but not less than all, the Offered Interest to theNon-Selling Member on the terms and conditions of the Matching Offer. Within ten Business Days after receipt of such Matching Offer, the Selling Member shall notify theNon-Selling Member and the Company of whether the Selling Member elects to accept the Matching Offer (a “ROFR Acceptance”) or decline the Matching Offer and continue to hold the Offered Interest. If no such notice is delivered prior to the expiration of suchten-Business Day period, the Selling Member shall be deemed to have declined the Matching Offer. If the Selling Member delivers a ROFR Acceptance, the closing of the Transfer of the Offered Interest contemplated by the Matching Offer pursuant to thisSection 10.05 (the “ROFR Closing”) shall occur not later than the later of (i) 30 days after the delivery of the ROFR Acceptance and (ii) five Business Days after the date on which all of the following conditions are satisfied or (to the extent permitted by applicable Law) waived by the applicable Member, or, subject to such satisfaction or waiver, on such other date as the Selling Member and theNon-Selling Member may mutually agree upon:

(i) there shall not be in effect any Law or Order that enjoins, restrains, prohibits or makes illegal the ROFR Closing; and

(ii) there shall have been obtained all material consents and approvals from Governmental Authorities that are required for each of the Selling Member and the Non-Selling Member, as applicable, to effect the ROFR Closing.

(d) At the ROFR Closing, (i) the Non-Selling Member shall deliver to the Selling Member the aggregate purchase price for the Offered Interest set forth in the Matching Offer and (ii) the Selling Member shall deliver to theNon-Selling Member good and marketable title to the Offered Interest, free and clear of all Encumbrances, pursuant to and in accordance with definitive agreements customary for such transactions and reasonably acceptable to the Selling Member and the Non-Selling Member;provided,however, that the representations and warranties to be made by the Selling Member shall be limited to the following customary representations and warranties related to authority, ownership and the ability to convey title to the Offered Interest (and the Selling Member shall agree to indemnify the Non-Selling Member for breach of such representations and warranties): (w) the Selling Member holds all right, title and interest in and to the Offered Interest that the Selling Member purports to hold, free and clear of all Encumbrances, (x) the obligations of the Selling Member in connection with the transaction have been duly authorized, (y) the documents to be entered into by the Selling Member have been duly executed by the Selling Member and delivered to theNon-Selling Member and are enforceable against the Selling Member in accordance with their respective terms and (z) neither the execution and delivery of documents to be entered into in connection with such transaction, nor the performance of the Selling Member’s obligations thereunder, will cause a breach or violation of the terms of any material Contract to which the Selling Member is a party or Law or Order applicable to the Selling Member (collectively, the “Required Representations”).

(e) If a Matching Offer for all of the Offered Interest is not set forth in a ROFR Election Notice prior to the ROFR Deadline, the Selling Member shall be entitled, in its sole discretion, either to continue to hold the Offered Interest or to Transfer all, but not less than all,

the Offered Interest to the Offeror at a price no less than the price pursuant to, and on other terms no more favorable to the Offeror than those of, the Offer Terms within 60 days following the ROFR Deadline (which period shall be extended by any period of time required to comply with applicable Law or the requirements of any Governmental Authority). In the event that the Selling Member shall not have consummated such Transfer within such period, any subsequent Transfer of the Offered Interest shall be subject to thisSection 10.05.

(f) The Company and each Member shall reasonably cooperate in connection with, and shall, as reasonably requested, take (or cause to be taken) all actions and execute (or cause to be executed) all instruments, in each case reasonably necessary or appropriate to effect, the Transfer of the Offered Interest to theNon-Selling Member or the Offeror, as applicable, pursuant to and in accordance with thisSection 10.05;provided,however, that neither the Company nor any Member shall be obligated to offer any consideration (except as expressly provided in thisSection 10.05), agree to any restriction or modify the rights and obligations of such Person under this Agreement in connection therewith.

(g) The obligations of the Selling Member and the rights of theNon-Selling Member set forth in thisSection 10.05 shall apply to each Offer made with respect to any Offered Interest, including any amendment to a prior Offer for which an Offer Notice has previously been delivered.

(b) Each of the Selling Member and theNon-Selling Member shall have the right to Transfer in aTag-Along Transfer a Percentage Interest equal to the product of (i) the Percentage Interest of such Selling Member orNon-Selling Member, as the case may be (expressed as a decimal)multiplied by (ii) the aggregate Percentage Interest that the Offeror proposes to buy as stated in the Offer Notice (expressed as a percentage).

(c) TheTag-Along Offer may be accepted by theNon-Selling Member at any time within 20 days after theNon-Selling Member’s receipt of theTag-Along Offer, which acceptance must be made by delivery of a written notice indicating such acceptance to the Selling Member.

(d) The Selling Member may elect in its sole discretion to terminate the proposed Transfer of any of its Membership Interest in theTag-Along Transfer (and shall not otherwise be deemed to owe any duty or responsibility to theNon-Selling Member to proceed with the Tag-Along Transfer), in which case, the obligations under thisSection 10.06 in respect of suchTag-Along Transfer shall cease.

(e) If for any reason the Selling Member elects to terminate or otherwise not to sell any of its Membership Interest in theTag-Along Transfer or suchTag-Along Transfer should fail to close, the Selling Member must comply with the provisions set forth inSection 10.05 and thisSection 10.06, to the extent applicable, prior to making any subsequent Transfer of all or any portion of its Membership Interest.

(b) In order to exercise the Drag-Along Right, the Selling Member shall send a written notice (a “Drag-Along Notice”) to theNon-Selling Member at least 15 days prior to the anticipated closing date of the Drag-Along Transfer setting forth the terms and conditions of such Drag-Along Transfer together with a statement asserting suchNon-Selling Member’s obligation to participate in such Drag-Along Transfer on substantially the same terms and conditions (including a pro rata portion, based on the then-applicable relative Percentage Interests of the Members, of the aggregate consideration attributable to the Membership Interests in such Drag-Along Transfer) as the Selling Member.

(c) TheNon-Selling Member shall be required to participate in the Drag-Along Transfer on the terms and conditions set forth in the Drag-Along Notice, and shall execute all agreements, instruments and certificates and take all actions necessary or desirable to effectuate the Drag-Along Transfer;provided,however, that theNon-Selling Member shall not be subject to the provisions of thisSection 10.07 if in the Drag-Along Transfer theNon-Selling Member: (i) is required to be subject to an obligation for indemnification or other liability that is in excess of either (A) the aggregate purchase price that suchNon-Selling Member actually receives in such Drag-Along Transfer or (B) itsprorata portion of the aggregate obligations for indemnification or other liability of the Selling Member and theNon-Selling Member (based on the then-applicable relative Percentage Interests of such Members), (ii) is subject to any obligations that are materially different and adverse as compared to the obligations of the Selling Member in such Transfer or (iii) is required to make representations and warranties other than the Required Representations.
