**ARTICLE 6 TERM**This Coal Lease is granted for a primary term of ten (10) years from the Effective Date ofthis Coal Lease, and for so long thereafter as the Coal is being produced by Lessee in “PayingQuantities,” but the period for mining shall not exceed twenty-five (25) years from the date of thefirst Coal delivery from the Leased Premises, plus any adjustment for Force Majeure. As used inthis Article, the term “Paying Quantities” means that, by midnight of the last day of the primaryterm of the Exploration Lease, the Lessee has commenced and thereafter continues the primaryremoval of Coal intended for sale and upon which royalties will be paid, subject to the provisionsof Force Majeure contained in Article 31 of this Coal Lease.No Coal may be mined from the Leased Premises after the end of such twenty-five (25) yearperiod, as extended by Force Majeure. However, after the end of the twenty-five (25) year periodfor mining or, when prior thereto, mining on the Leased Premises otherwise ceases, this Coal Leaseshall continue for as long as is necessary to allow Lessor to conduct activities necessary orappropriate to reclaim the land, salvage equipment, and comply with applicable laws andregulations. Reclamation shall be deemed complete at time of final bond release. If, at the endof twenty-five (25) years, there is mineable Coal remaining within the Leased Premises that wouldbe sterilized, bypassed, or forever forsaken by the termination of mining of Coal by Lessee,adjustments to this termination date may be made by the mutual consent of Lessor and Lessee.**ARTICLE 7 ROYALTY PAYMENTS**7.1 **Minimum Royalty**. Lessee shall pay, or cause to be paid, a royalty to the Superintendentfor the use and benefit of Lessor, on or before the twenty-fifth (25th) day of each calendar monthduring the term hereof on all Coal mined and shipped from the Leased Premises during the precedingcalendar month. The amount of minimum royalty, hereinafter “Minimum Royalty,” paid shall be anamount per ton equal to 6.5% of the sales price per ton sold and delivered F.O.B. Mine at loadoutinto or onto a Carrier, hereinafter “Sales Price.” The Minimum Royalty of 6.5% may be increased asprovided in provision 7.3 below.7.2**Additional Royalty**. Lessee shall pay, or cause to be paid, an additional royalty to theSuperintendent for the use and benefit of Lessor, on or before the twenty-fifth (25th) day of thecalendar month following each calendar quarter during the term hereof on all Coal mined and shippedfrom the Leased Premises during the preceding calendar quarter. The amount of additional royaltyshall be determined as follows: a. Lessee shall determine the Sales Price less Minimum Royalty andany production taxes, hereinafter “Base Price.” The Base Price is determinedusing the formula and methodology set forth in Appendix A attached hereto. Theproduction tax components shown in Appendix A are those currently in effect.If, in the future, taxes levied and payable change, taxes in effect at the timeof sales will be included in the formula and methodology used in determiningBase Price. The amount of additional royalty shall be equal to one-third (1/3)the increase in the Base Price per ton above $5.157 per ton,hereinafter “Initial Base Price.” The Initial Base Price was determinedusing the formula and methodology set forth in Appendix A for a Sales Priceof $7.38 per ton.

 b. The Initial Base Price of $5.157 per ton is effective July 1,2004, and will be adjusted quarterly thereafter on January 1, April 1, July 1,and October 1 during the term hereof, hereinafter the “Adjustment Date.” TheInitial Base Price as adjusted shall be used to determine the additionalroyalty for the quarter preceding the Adjustment Date. The Initial Base Priceshall be adjusted to reflect 85% of any increase in the “GDP-IPD” in accordancewith the definitions, formula, and methodology set forth in Appendix B attachedhereto and effective on the Adjustment Date. c. After April 1, July 1, October 1, and January 1 each yearduring the term hereof, the Lessee shall determine the Base Price for all Coalmined and shipped on a year-to-date basis during all of the previous quartersfor the calendar year. The additional royalty due for all Coal mined andshipped on a year-to-date basis will then be computed. The additional royaltydue for the previous quarter will then be equal to the total additional royaltyas computed on a year-to-date basis less the additional royalty payments paidfor all quarters during the current year prior to the quarter being paid.Appendix C hereto attached shows an example of the formula and methodology fordetermining the additional royalty payment for a quarter.7.3 **Royalty Offset**. If the amount of taxes payable to the Crow Tribe is reduced for anyreason (including, but not limited to, a reduction in the Montana tax rates) after this Coal Leasetakes effect, the Minimum Royalty provided in Article 7.1 and payable to the Crow Tribe shall beincreased by an amount necessary to offset the reduction in taxes, so that the total taxes androyalty paid to the Crow Tribe equals the current taxes in existence in 2003, plus the royaltyotherwise payable under this Coal Lease; provided, however, that the maximum royalty rate shallnot exceed 12.5% of the Sales Price; and provided further that if Westmoreland notifies the CrowTribe that the increased royalty will result in serious difficulty in marketing the coal, or lossof sales under current long term coal sales agreements, the Crow Tribe will negotiate in good faithon reducing the amount of increase in the royalty rate. If a tax increase occurs, following a taxreduction and royalty increase per this section, then there will be a commensurate royaltyreduction, so that the total taxes and royalty paid remains as provided in the first sentence ofthis Section 7.3.7.4 **Royalty Cap and Additional Royalty Adjustment**. Notwithstanding Sections 7.1, 7.2, or7.3, the total royalty paid to Lessor from the mining operations under this Coal Lease shall neverexceed 12.5% of the Sale Price.7.5**Measure of Quantity for Royalty Payment**. The quantity of all Coal mined and shipped bythe Lessee shall be determined by railroad or truck scales, belt weightometers, or other meansmutually agreed upon.

All tax provisions in the Exploration Agreement, including,without limitation, Sections 15, 17, and 19, shall apply to all mining and Mining Activitiesundertaken pursuant to this Coal Lease.8.2 **Tax Obligation and Calculation**. On Coal mined and shipped from the Mining Area pursuantto this Coal Lease, Lessee will from time to time pay to the Lessor a tax equal to the Montana coalseverance tax existing at the time the Exploration Agreement is executed and applicable to themining of Coal generally within the state of Montana and a tax equal to the Montana state grossproceeds tax existing at that time and applicable to the mining of Coal generally within the state,less whatever amount is required to be paid in severance and gross proceeds taxes to the state ofMontana or its political subdivisions. The tax shall be levied on the Sales Prices of Coal asdefined in Section 7.1, less any applicable deductions.Compliance with the terms of this Coal Lease shall satisfy any obligation which Lessee mayhave now, or at any time hereafter, to pay any severance or other tax to Lessor pursuant to any taxordinance which now exists or may be adopted by Lessor hereafter. Lessor shall not attempt toassess or collect any tax or other amount from Lessee except as provided for in this Coal Lease orthe Exploration Agreement.Nothing in this Lease is to be construed as an admission that Montana has any right to taxcoal on the Crow Reservation. In the event the Crow Tribe litigates this issue, Lessee willcooperate reasonably to provide information to the Lessor.8.3 **Maximum Tax**. The amount of tax payable to Lessor under provision 8.2 will not exceed theamount that otherwise would be payable by a Coal operator on non-tribal lands to Montana or itspolitical subdivisions, giving effect to all allowable deductions and credits, if Lessor’sactivities were fully taxable by Montana or its political subdivisions.8.4 **Reporting and Payment**. Lessee shall provide to the Lessor all of the information thatLessee may be, or otherwise would be, required to provide to the state of Montana or its politicalsubdivisions in satisfaction of the requirements of Montana’s severance tax law and gross proceedstax law at the same time that such information is, or otherwise would be, provided to the state ofMontana or to its political subdivisions. Lessee shall pay any amounts due to the Lessor underthis Article, and provide an accounting of, and explanation for, said amounts, at the same timethat Montana’s severance and gross proceeds taxes are being, or otherwise would be, paid. Theconfidentiality provisions of Article 18 shall apply equally to this Article. All tax paymentsshall be made according to the applicable federal regulations governing royalty payments for Indiancoal. Where the express terms of this Agreement differ from any provisions of the applicablefederal regulations, the terms of this Agreement shall control.

8.5 **Changes in Rate of Tax**. a. **Tax Reduction**. In the event that either the Montana state severance tax or gross proceeds taxshould be repealed or reduced below its current level, then amounts paid by Lessee under Section8.2 shall be reduced accordingly. Further, an adjustment to royalty will be made in accord withArticle 7. In addition, the parties shall have the rights provided herein below: (1) Lessor may require Lessee to negotiate withLessor on the amount of severance and/or gross proceeds taxes, if any,which Lessee will pay to the Lessor by giving Lessee notice of anintent to renegotiate this provision with respect to a severance taxand/or gross proceeds tax within ninety (90) days (unless otherwiseagreed) after the effective date of the act of the Montana legislatureor after action of any Montana political subdivision effecting suchreduction.  (2) Unless otherwise agreed, negotiations shallcommence within thirty (30) days after Lessee’s receipt of the Lessor’snotice of intent to renegotiate.  (3) Lessee’s obligation to pay a severance and/or agross proceeds tax to Lessor under this Coal Lease shall be suspendedduring the period of renegotiation from the last day of the month inwhich the intent to renegotiate is received by Lessor.

In the event Lessor and Lessee are unable to reach anagreement on the amount of taxes to be paid to the Lessor within sixty (60) days of thecommencement of negotiations provided for in 8.5a.(1) (excluding time required to seek approval ofany such agreement at the next meeting of Lessor’s Tribal Legislature), then, unless otherwiseagreed, either Lessor or Lessee may resolve the issue of the proper amount of taxes payable byLessee to Lessor under this Coal Lease through binding arbitration. The arbitration procedureshall be that provided in the Exploration Agreement at Section 26. The arbitrators shall be askedto arrive at a reasonable rate of severance and gross proceeds tax which, when combined with theroyalty received by the Crow Tribe, accomplishes the following goals: provision to Westmoreland ofa reasonable profit and rate of return on its investment, when compared with similar (includingnon-tribal) mining operations located within Lessee’s market area; whileproviding a reasonable return to the Crow Tribe from the mining of its mineral assets in the formof royalty and severance and gross proceeds taxes.

The parties recognize the Crow Tribe’s legal position that the Stateof Montana lacks jurisdiction to regulate Westmoreland’s activities under this Agreement that occuron or affect lands within the exterior boundaries of the diminished Reservation (which include allof the Prospect Area and Mining Area), while the State asserts jurisdiction to regulateWestmoreland’s activities outside the boundaries of the diminished Reservation (includingWestmoreland’s existing mining operations on Tract III within the “ceded strip”).The Lessee shall comply with all applicable requirements of the law, including the SurfaceMining Control and Reclamations Act of 1977, and all regulations promulgated thereunder, includingthose codified at 30 CFR part 750.Lessee recognizes that the Crow Tribe may seek and be granted legal authority pursuant tofederal law (including future acts of Congress) to operate and administer certain environmentalregulatory programs within the Crow Indian Reservation that would otherwise be operated oradministered by federal agencies, including, but not limited to, SMCRA and the Clean Water Act.Lessee will not take any actions opposing the Tribe’s efforts to obtain such authority. If at anytime in the future the Crow Tribe gains the legal right and ability to regulate those activitiesdescribed above in this Article 13, and desires to establish and undertake such regulation, Lesseeagrees to negotiate in good faith to amend this Agreement to allow such regulation of itsactivities upon such terms as shall guarantee: (a) no net increase in Lessee’s costs; (b) noduplication, overlap, inconsistency, or conflict with, between, or among competing laws andregulations issued and applied by any other government with the right and power to impose suchregulation; and (c) Lessee shall not be subjected to inspection, regulation, and enforcement bymore than one governmental entity.**ARTICLE 14 USE OF LANDS OUTSIDE THE LEASED PREMISES**Subject to Article 4 of this Coal Lease, Lessee shall be entitled to make use of tribalsurface lands lying outside the Leased Premises reasonably required for Mining Activities on theLeased Premises, including, but not limited to, the construction, operation, and maintenance ofroads, power lines, railroads, conveyors, and any road easements required for landowner access.Lessee shall, to the extent deemed by it to be reasonably feasible and prudent, utilize such landsin a manner which will minimally impact the Lessor’s use of such lands, including mining operationsconducted by others.

Any surface lands within the Crow Reservation necessary or convenient forMining Activities in excess of permissible acreage limitations may first beacquired by Lessor, and leased back to the Lessee at the surface rental ratesspecified in this Coal Lease.    If Lessor declines to acquire such lands, then such lands may be acquired byLessee for Lessor, such acquisition to be evidenced by an appropriate deedin Lessor’s name. Lessor shall then execute and deliver a lease of saidlands back to Lessee which grants Lessee all rights to use provided in thisCoal Lease and the Exploration Agreement, without cost, (except as otherwiseprovided for in this Coal Lease or the Exploration Agreement) any and all ofthe land and any water rights associated with such land for MiningActivities until the Mining Activities on that land have been completed, andall uses by Lessee for any purposes connected with mining or reclamationcease.
