In the event such a challenge cannot be mutually resolved between PCC and D-R, it shall become a Dispute under this Agreement and resolved in accordance with Article VI hereof. 3.2. Amendment to Collective Bargaining Agreements. (a) D-R and PCC acknowledge that from time to time it may be necessary for D-R or its Affiliates, Successors, Assigns, Lessees or Contractors to re-negotiate the terms of the Collective Bargaining Agreements. In the 9 event that D-R or its Affiliates, Successors, Assigns, Lessees or Contractors agrees to any modifications or amendments to the benefits provided under, or to the plan design of, any Classified Employee Retiree Medical Plan ("Amended Medical Plan"), to the extent allowed by law PCC shall have the right to determine whether to satisfy the Post-94 Retiree Medical Liabilities through the Classified Employee Retiree Medical Plan(s) or through any Amended Medical Plan, provided, however, in the event a claim against D-R or PCC is filed with a court or administrative agency with jurisdiction over the claim, asserting that the Post-94 Retiree Medical Liabilities must be provided through an Amended Medical Plan, then, (i) in the event the claim is asserted against PCC, PCC may elect to satisfy the Post-94 Medical Liabilities though an Amended Medical Plan, and (ii) in the event the claim is asserted against D-R, PCC shall agree, upon the written request of D-R, to satisfy such Liabilities through the Amended Medical Plan. (b) In the event an Amended Medical Plan is negotiated by D-R or its Affiliates, Successors, Assigns, Lessees or Contractors, PCC shall have the right, at its sole cost and expense, to submit to the actuarial firm of Mercer Human Resource Consulting, or another actuarial firm mutually acceptable to PCC and D-R (the "Actuarial Firm"): (i) the Classified Employee Retiree Medical Plan(s) pursuant to which PCC is satisfying the Post-94 Retiree Medical Liabilities; and (ii) the Amended Medical Plan. The Actuarial Firm will perform a relative value analysis of each plan, including its administration, using actuarial methods designed to estimate the cost difference between two or more plans. This analysis will compare the coverage provisions of the Amended Medical Plan to those of the Classified Employee Retiree Medical Plan(s) to determine the relative cost of 10 each plan based on the respective benefit design and services covered. This relative cost will be calculated as a factor representing the percentage cost difference of the Amended Medical Plan relative to the Classified Employee Retiree Medical Plan(s) ("Relative Cost Factor"). If the relative value analysis demonstrates that the cost of the Amended Medical Plan, including its administration, exceeds the cost of the Classified Employee Retiree Medical Plan(s), including its administration, and PCC chooses or is required to satisfy the Post-94 Retiree Medical Liabilities through the Amended Medical Plan, D-R will reimburse PCC that amount by which the projected cost to be incurred by PCC for that plan year to satisfy the Post-94 Retiree Medical Liabilities under the Amended Medical Plan ("Amended Plan Projected Cost") exceeds the amount PCC would have expected to incur under the terms of the Classified Employee Retiree Medical Plan(s) ("Classified Plan Expected Cost"). This amount shall be divided and reimbursed in four equal installments at the end of each calendar quarter. The Amended Plan Projected Cost and the Classified Plan Expected Cost will be estimated based on actuarial methods and factors, including the historical experience of the plans, expected medical cost and utilization trend, demographic differences and the Relative Cost Factor. (c) Either PCC or D-R shall have the right to request that the Actuarial Firm perform a new relative value analysis of the Classified Employee Retiree Medical Plan(s) and the Amended Medical Plan, or any successor thereto: (i) at the termination of any collective bargaining agreement to which D-R or any of its Affiliates, Successors, Assigns, Lessees or Contractors are signatory or every five years, whichever occurs first; and (ii) in the event legislation is enacted which affects the terms or costs of any such plan. The party requesting such new relative value analysis shall pay all costs and expenses associated therewith. 3.3. PCC Amendments to the Medical Plans. If PCC has or secures from the UMWA a right to change the medical plan(s) by which it satisfies the Post-94 Retiree Medical Liabilities, PCC may make any 11 such changes so long as they do not impose any liability or additional costs or obligations on D-R or its Affiliates, Successors, Assigns, Lessees or Contractors. 3.4. D-R Provision of Benefits. D-R and PCC acknowledge that there is a possibility that participants for which PCC is required to satisfy the Post-94 Retiree Medical Liabilities may demand under the Collective Bargaining Agreements that D-R or its Affiliates, Successors, Assigns, Lessees or Contractors, rather than PCC, provide their retiree medical benefits ("Participants"). In the event D-R or its Affiliates, Successors, Assigns, Lessees or Contractors is required to provide such retiree medical benefits for any such Participant: (a) PCC shall reimburse D-R or its Affiliates, Successors, Assigns, Lessees or Contractors the Classified Plan Expected Cost, prorated for each such Participant, which will be estimated based on actuarial methods and factors, including the historical experience of the plans, expected medical cost and utilization trend, demographic differences and the Relative Cost Factor. This amount shall be divided and reimbursed in four equal installments at the end of each calendar quarter. (b) Either PCC or D-R shall have the right to request that the Actuarial Firm perform a new relative value analysis of the Classified Employee Retiree Medical Plan(s) and the Amended Medical Plan, or any successor thereto: (i) at the termination of any collective bargaining agreement to which D-R or any of its Affiliates, Successors, Assigns, Lessees or Contractors are signatory or every five years, whichever occurs first; and (ii) in the event legislation is enacted which affects the terms or costs of any such plan. The party requesting such new relative value analysis shall pay all costs and expenses associated therewith. 12 ARTICLE IV WORKERS' COMPENSATION AND FEDERAL BLACK LUNG LIABILITIES 4.1. General. In order to assist PCC with regard to the satisfaction of the Workers' Compensation and Federal Black Lung Liabilities, PCC and D-R agree as follows: (a) Administration. PCC or one or more of its Affiliates shall be solely responsible for administering the Workers' Compensation and Black Lung Liabilities, including making such determinations, awarding and denying such benefits, seeking such administrative and judicial rulings and remedies and taking all such other actions as PCC shall deem necessary or appropriate. (b) Notices and Communication. (i) D-R and PCC agree to cooperate with each other in providing any notices that may be necessary to the appropriate Governmental Authority regarding the allocation between PCC, on the one hand, and D-R, on the other hand, of the Workers' Compensation and Federal Black Lung Liabilities. (ii) In the event D-R or any of its Affiliates, Successors, Assigns, Lessees or Contractors receive any Communications that are related to the Workers' Compensation and Federal Black Lung Liabilities, D-R agrees that it shall, and shall cause its Affiliates, Successors, Assigns, Lessees or Contractors to, send promptly to PCC or its designated Affiliate a copy of any such Communications. (iii) D-R and PCC agree to cooperate with each other in providing such notices of the allocation of liabilities under the Acquisition 13 Agreement as D-R and PCC deems appropriate to any insurer or third party administrator providing services or benefits related to the Workers' Compensation and Federal Black Lung Liabilities. 4.2. Litigation and Disputes. PCC shall have the right to resolve or defend against any claim that is related to the Workers' Compensation and Federal Black Lung Liabilities in such manner as PCC in its discretion deems appropriate, in accordance with such procedures as PCC deems appropriate and with the controlling Workers' Compensation Act and federal black lung Laws, including raising the defense that D-R is the responsible operator under the federal black lung Laws because D-R or its Affiliates, Successors, Assigns, Lessees or Contractors is a successor-in-interest to PCC or its Affiliates; provided, however, that D-R shall have the right to respond that PCC is the responsible operator under the federal black lung Laws notwithstanding D-R's acquisition of the Purchased Assets. PCC also shall have the right to institute or defend against any litigation related to the Workers' Compensation and Federal Black Lung Liabilities, except that PCC shall promptly notify D-R of any workers' compensation or federal black lung claim in which it intends to assert that D-R is responsible for payment of the same under the Acquisition Agreement, in which case D-R shall have the right to intervene in any such action to oppose PCC's position. Any dispute as to which entity is the responsible entity for such workers' compensation claims shall be determined in accordance with the Workers' Compensation Acts, and any dispute as to which entity is the responsible operator for such black lung claims shall be determined in accordance with the federal black lung Laws. 4.3. No Adverse Changes. D-R agrees that it will, and will cause its Affiliates, Successors, Assigns, Lessees or Contractors to, use its or their commercially reasonable 14 efforts to retain in effect any lawful program or practice of PCC or its Affiliates in effect at Closing that is intended to reduce employer liability or the length of time an employee is entitled to receive benefits under the Workers' Compensation Act. 4.4. Recurrence of Prior Claims. In the event D-R or any of its Affiliates, Successors, Assigns, Lessees or Contractors receives a claim under the applicable Workers' Compensation Acts or federal black lung Laws and D-R or its Affiliates, Successors, Assigns, Lessees or Contractors believes in good faith that such claim relates to, or is a recurrence of, a prior claim that constituted a Workers' Compensation or Federal Black Lung Liability (a "Recurrence Claim"), the provisions of this Section 4.4 shall govern. D-R shall promptly notify PCC of any Recurrence Claim and the basis for its determination that such claim is a Recurrence Claim prior to communicating its determination to any other person or entity. If PCC agrees with D-R that such claim is a Recurrence Claim, such claim shall be deemed a Workers' Compensation and Federal Black Lung Liability, and the rights and obligations of the parties shall be as provided in this Article IV. If PCC disagrees with D-R's position, the matter will be submitted to the appropriate Governmental Authority for a determination, with each side being responsible for its respective costs in such procedure. D-R recognizes that in the event the employee who has filed the claim disagrees with the position of the parties with respect to a Recurrence Claim, the employee may file a claim with the appropriate Governmental Authority for a determination. In any such case, PCC and D-R shall each have the right to defend its position, with each side bearing the cost of its own defense. 15 ARTICLE V EMPLOYEE RELATED LIABILITIES 5.1. Employee Related Liabilities. In order to assist PCC with regard to the satisfaction of the Employee Related Liabilities, PCC and D-R agree as follows: (a) Administration. PCC or one or more of its Affiliates shall be solely responsible for administering the Employee Related Liabilities, making such determinations, awarding and denying such benefits, seeking such administrative and judicial rulings and remedies and taking all such other actions as PCC shall deem necessary or appropriate.

(iii) Within a reasonable period of time after the panel forms must be returned under the Collective Bargaining Agreements, PCC shall provide all forms that have been returned to D-R. (iv) PCC shall notify D-R of any Classified Employee on Schedule 3.13(b) of the Acquisition Agreement who failed to submit a panel form as required under the Collective Bargaining Agreements, and PCC and D-R shall cooperate with each other to determine the final status of all Classified Employees on Schedule 3.13(b) of the Acquisition Agreement. ARTICLE VII DISPUTE RESOLUTION Disputes under or alleged violations of this Agreement shall be handled in accordance with the Dispute resolution procedure set forth in Article VII of the Indemnification and Guaranty Agreement. 18 ARTICLE VIII TERM The term of this Agreement shall commence as of the Closing Date and shall continue through the completed satisfaction of all of the Coal Act Liabilities, Post-94 Retiree Medical Liabilities, Workers' Compensation and Federal Black Lung Liabilities and the Employee Related Liabilities.

(a) To the extent permitted by Law and on a timely basis, D-R agrees to take any reasonable action, provide information and execute any appropriate documents, and shall cause its Affiliates, Successors, Assigns, Lessees or Contractors to take any reasonable action, provide information and execute any appropriate documents, that PCC reasonably requests in order to assist PCC with regard to the administration and satisfaction of the Coal Act Liabilities, Post-94 Retiree Medical Liabilities, Workers' Compensation and Federal Black Lung Liabilities and the Employee Related Liabilities. Upon written request by D-R, PCC shall reimburse D-R for costs above $10,000 per year that are reasonably incurred by D-R or its Affiliates as a result of actions taken by it or them under this Agreement. Prior to payment of such costs, PCC shall be entitled to receive a detailed invoice of such costs from D-R if so requested by PCC.

The parties have used commercially reasonable efforts to include the correct tax ticket numbers in an exhibit to be attached to and referenced in the Conveyance Deeds in order to identify the Real Property being transferred to D-R. To the extent it is later determined that different tax ticket numbers should have been included on or removed from the Conveyance Deeds, each party agrees to take any reasonable action, provide information and execute any appropriate documents, and shall cause its Affiliates, Successors, Assigns, Lessees or Contractors to take any reasonable action, provide information and execute any appropriate documents, that the other party reasonably requests in order to ensure that the Conveyance Deeds reference the tax ticket numbers associated with the actual Real Property transferred to D-R. 9.2. Continuing Obligations.

Notwithstanding the foregoing, in the event PCC fails to take such actions as are necessary to comply with its obligations under the Acquisition Agreement and this Agreement with respect to any of the Coal Act Liabilities, Post-94 Retiree Medical Liabilities, Workers' Compensation and Federal Black Lung Liabilities or the Employee Related Liabilities within a reasonable time after receiving notice from D-R that attempts have been or are being made to obtain information concerning or to impose any of the Coal Act Liabilities, Post-94 Retiree Medical Liabilities, Workers' Compensation and Federal Black Lung Liabilities or the Employee Related Liabilities on D-R or any of its Affiliates, Successors, Assigns, Lessees or Contractors, D-R shall be permitted to communicate with the appropriate Third Party regarding PCC's obligations with respect to such Coal Act Liabilities, Post-94 Retiree Medical Liabilities, Workers' Compensation and Federal Black Lung Liabilities or the Employee Related Liabilities.
