and all improvements made by ▇▇▇▇▇▇▇▇▇▇▇▇ on the Prospect Area, or any part of the Crow Reservation, under the terms of this Exploration Agreement and during the period of this Exploration Agreement, shall be done in a miner-like and proper manner, so that the Prospect Area shall be carefully operated and the minerals contained in the Prospect Area may be sampled and evaluated in an economical and environmentally responsible manner.

	a.		Roads. ▇▇▇▇▇▇▇▇▇▇▇▇ may use existing roads, if any, on the South Extension and may construct and maintain at its own expense any additional roads within the Prospect Area that are necessary in carrying on prospecting and exploration work. The Crow Tribe consents to the construction and use of such roads and will cooperate in obtaining any needed consents or approvals from any government entity, including the BIA.
	b.		No Public Right. The public shall obtain no rights to any roads constructed by ▇▇▇▇▇▇▇▇▇▇▇▇, nor shall ▇▇▇▇▇▇▇▇▇▇▇▇ be obliged to maintain said roads for use by any other person, or permit any other persons to use them, and on termination of this Exploration Agreement, or if at any time it becomes unnecessary for ▇▇▇▇▇▇▇▇▇▇▇▇ to use any roads for conducting authorized operations, the right to use and any obligation to maintain the roads shall cease and, subject to any need to use roads to complete reclamation, all rights shall revest in the surface owner.

     2.3 Licensing and Permits. Prior to exercising the exploration rights set forth in this Exploration Agreement, ▇▇▇▇▇▇▇▇▇▇▇▇ shall obtain all necessary licenses and permits from the federal government. The parties recognize that time is of the essence in ▇▇▇▇▇▇▇▇▇▇▇▇’▇ ability to conduct exploration within the Prospect Area, and it is contemplated that ▇▇▇▇▇▇▇▇▇▇▇▇ will be able to obtain a federal approval of a prospecting permit for the limited purpose of conducting those exploration activities immediately after the Crow Tribe’s approval of this Agreement, and prior to federal approval pursuant to the requirements of the IMDA.

     2.5 Reservation of Right to Grant Additional Exploration Licenses. The Crow Tribe retains the right to grant exploration rights for minerals other than Coal, on the Prospect Area designated by ▇▇▇▇▇▇▇▇▇▇▇▇, but the parties agree any exploration rights so granted shall not interfere with the exploration rights of ▇▇▇▇▇▇▇▇▇▇▇▇. Any exploration rights granted to parties other than ▇▇▇▇▇▇▇▇▇▇▇▇ covering the Prospect Area shall provide that activities conducted pursuant to such rights are subordinate to the exploration rights of ▇▇▇▇▇▇▇▇▇▇▇▇ and thus shall not interfere with ▇▇▇▇▇▇▇▇▇▇▇▇’▇ exploration rights and shall further provide any selection of a mining (including drilling for hydrocarbons) area by such third parties shall be made only after ▇▇▇▇▇▇▇▇▇▇▇▇ has selected its Mining Area in accordance with Section 8 of this Exploration Agreement, and after selection, ▇▇▇▇▇▇▇▇▇▇▇▇ shall have the exclusive use of said Mining Area. To the extent practicable, ▇▇▇▇▇▇▇▇▇▇▇▇ shall conduct its exploration activities so as not to diminish the quantity or value of the Tribe’s Coal or coal bed methane resources in seams that ▇▇▇▇▇▇▇▇▇▇▇▇ does not intend to mine under this Agreement.

SECTION 3 OPTION TO LEASE

     3.1 Exclusive Option to Lease. ▇▇▇▇▇▇▇▇▇▇▇▇ shall have the exclusive option to lease the Crow Tribe’s Coal in the Prospect Area. Said option shall be exercised, if at all, upon completion of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ exploration and reserve analysis in the Prospect Area or no later than April 1, 2005, unless ▇▇▇▇▇▇▇▇▇▇▇▇ elects the extension provided in provision 5.4 of this Exploration Agreement.

     3.2 Exercise of Option. If ▇▇▇▇▇▇▇▇▇▇▇▇ elects to exercise the option granted and receive a Coal Lease to the Mining Area, it shall notify the Crow Tribe in a manner in accordance with provision 25.3 of this Exploration Agreement.

The Crow Tribe shall, on the receipt of the notice of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ intention to exercise its option, deliver the fully executed lease to ▇▇▇▇▇▇▇▇▇▇▇▇.

     3.3 Conversion of Option into Right of First Refusal. The option to demand and receive a Coal Lease, if not exercised, shall convert into a right of first refusal for as long as ▇▇▇▇▇▇▇▇▇▇▇▇ operates the Absaloka Mine. If the Crow Tribe receives an offer to lease Coal in the Prospect Area from any party other than ▇▇▇▇▇▇▇▇▇▇▇▇ during the right of first refusal period, it

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

must present to ▇▇▇▇▇▇▇▇▇▇▇▇ an offer to lease said Coal on the same terms as said offer, and ▇▇▇▇▇▇▇▇▇▇▇▇ shall have sixty (60) days within which to accept or reject.

          This right of first refusal shall not apply if, after ▇▇▇▇▇▇▇▇▇▇▇▇ fails to exercise its option, the Crow Tribe decides to develop the Coal in the Prospect Area itself, or through any entity or joint venture of which the Crow Tribes owns not less than one-half (i.e., a Tribally-owned mine); provided, however, that ▇▇▇▇▇▇▇▇▇▇▇▇ will be given the opportunity to bid on any general contract for operating a Tribally-owned mine in the Prospect Area.

          The Crow Tribe must inform any offeror no later than five (5) days after receiving any offer of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ right of first refusal.

     3.4 Machinery and Equipment. No equipment, tools, machinery, improvements, or personal property of any nature or description brought or placed in the property prior to the exercise of this option by ▇▇▇▇▇▇▇▇▇▇▇▇ for use in the work shall become a fixture.

          All the equipment, structures, improvements, and other property shall remain the property of ▇▇▇▇▇▇▇▇▇▇▇▇, subject to removal by ▇▇▇▇▇▇▇▇▇▇▇▇. If ▇▇▇▇▇▇▇▇▇▇▇▇ does not exercise this option, it shall be entitled to remove all equipment, tools, machinery, structures, improvements, and personal property from the property within ninety (90) days after the expiration of this option.

     3.5 Title of Owner. The Crow Tribe represents that it is the lawful owner of all minerals located in the Mining Area, as specifically described herein, and such Tribal Land as is located in the Mining Area. The Crow Tribe further represents the minerals covered by this Exploration Agreement are each free from all liens and encumbrances of every nature and description.

          During the period of this option, the Crow Tribe shall protect all of its property in the Mining Area from any and all liens except those arising from the acts of ▇▇▇▇▇▇▇▇▇▇▇▇ on the Mining Area.

          The Crow Tribe shall not encumber any of its property in the Mining Area or any part of it and shall furnish to ▇▇▇▇▇▇▇▇▇▇▇▇ satisfactory evidence of good title to same not less than ninety (90) days after any written request from ▇▇▇▇▇▇▇▇▇▇▇▇ to do so.

          Nothing herein shall be construed as prohibiting the Tribe from pledging or assigning payments due the Tribe under this Agreement, including lump sum payments, royalties, and taxes.

     3.6 Unavoidable Delays. Any time lost by ▇▇▇▇▇▇▇▇▇▇▇▇ in the event of Force Majeure, as that term is defined in Section 11 of this Exploration Agreement, shall not run against the time specified in this Exploration Agreement for exercise of this option.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

SECTION 4 SETTLEMENT WITH MMS

     As additional consideration for this Exploration Agreement, the parties agree to settle the matters recited in the Settlement Agreement attached hereto as Exhibit C by executing same and carrying out its terms.

     Except for the Exploration License granted in Section 2, the Crow Tribe’s performance of this Exploration and Option to Lease Agreement is contingent upon the Tribe’s receipt of the payment due under said Settlement Agreement as provided in Section 5.2 below.

SECTION 5 LUMP SUM PAYMENTS

     Payments. In consideration for the execution of this Exploration Agreement, as well as the grant of the rights and obligations contained in this Exploration Agreement, and the agreement to settle the MMS dispute per Section 4, ▇▇▇▇▇▇▇▇▇▇▇▇ shall make lump sum payments as follows:

     5.1 [*****] upon final approval of this Exploration Agreement, including the Coal Lease and the MMS Settlement Agreement. For purposes of this contingency, the term “final approval” shall mean binding approval of this Exploration Agreement and Coal Lease, and all exhibits and agreements attached thereto, by the Crow Tribe by signed approval of the Executive Branch of the governing body of the Crow Tribe of Indians and final and binding approval by the legislature of the Crow Tribe pursuant to Article V, Section 2(d), of the Constitution of the Crow Tribe. A true and correct copy of the Crow Tribal Legislative Act No. CLB 0402, enacted February 10, 2004, and approved February 12, 2004, approving this Exploration Agreement and the Coal Lease, and all exhibits and attachments, and authorizing the Executive of the Crow Government to execute said agreements on behalf of the Crow Tribe is attached hereto as Exhibit “D.”

          If ▇▇▇▇▇▇▇▇▇▇▇▇ elects not to exercise its option, or if this Exploration Agreement is not approved by the Secretary as provided in Section 21, then the [*****], paid pursuant to this, shall be treated as an advance of royalty and taxes under the existing Tract III Lease and shall be reimbursed pro rata over the next twenty-four (24) months following expiration of the term of the option.

     5.2 One Million Five Hundred Thousand Dollars and 0/100 ($1,500,000), following approval per Section 5.1, and upon approval and execution of the Settlement Agreement attached as Exhibit C, according to its terms, releasing ▇▇▇▇▇▇▇▇▇▇▇▇ from any further royalties, assessments, or taxes of any kind based on option payments received from Xcel Energy (formerly NSP), from the period from 1986 to 1999, as full, final and complete settlement of the MMS dispute. Following approval, execution, and payment as provided herein, the MMS Settlement Agreement shall survive any of the following: termination of this Exploration Agreement or the Coal Lease, or failure or refusal of the Secretary to approve same, and shall be permanent and binding according to its terms.

          This lump sum payment for the MMS Settlement Agreement is not contingent upon federal approval of this Exploration and Option to Lease Agreement or associated prospecting permit or Coal Mining Lease and is non-recoupable according to the terms of the Settlement Agreement, as long as it has been separately approved according to its terms.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     5.3 If ▇▇▇▇▇▇▇▇▇▇▇▇ elects to exercise the option specified in Section 3 of this Exploration Agreement, ▇▇▇▇▇▇▇▇▇▇▇▇ shall pay the Crow Tribe the sum of [*****], which shall be paid, less any advance payment as provided in Section 5.4 below, within ten (10) days of exercising the option.

     5.4 ▇▇▇▇▇▇▇▇▇▇▇▇ may extend its exploration rights and the date for exercising its option from April 1, 2005, to June 1, 2006, by paying an additional [*****] to the Crow Tribe on or before April 1, 2005. If ▇▇▇▇▇▇▇▇▇▇▇▇ subsequently elects to exercise its right to mine, said [*****] shall be an advance on the consideration required for ▇▇▇▇▇▇▇▇▇▇▇▇’▇ right to elect its option as specified in provision 5.3. If ▇▇▇▇▇▇▇▇▇▇▇▇ elects not to exercise its option, then [*****] of this payment shall be treated as an additional advancement on royalty and taxes under the existing Tract III Lease to be reimbursed over the next eight (8) quarters.

     5.5 With the exception of the contingencies outlined in Sections 5.1 and 5.4 of this Exploration Agreement, the above described lump sum payments shall not be recoupable against future royalties, taxes, or any other amounts ▇▇▇▇▇▇▇▇▇▇▇▇ owes the Crow Tribe.

     5.6 All lump sum payments to the Crow Tribe shall be made to the Superintendent in trust for the use and benefit of the Crow Tribe.

Current Tract III Lease Royalty Rates shall remain in effect on all sales made under contracts existing on December 1, 2004, through their term, or any price renegotiation date, whichever comes first, but ▇▇▇▇▇▇▇▇▇▇▇▇ shall agree that on such sales, the Crow Tribe will realize an overall royalty of not less than that provided in Article 7 of the Coal Lease.

     6.2 Extension of Tract III Lease. If ▇▇▇▇▇▇▇▇▇▇▇▇ exercises its option to lease under this Exploration Agreement, the parties recognize that ▇▇▇▇▇▇▇▇▇▇▇▇ must use its current Tract III Facilities Area for the efficient production of Coal from the Mining Area for the entire period during which ▇▇▇▇▇▇▇▇▇▇▇▇ conducts Mining Activities in the Mining Area. The parties further recognize that it is to their mutual interest and benefit to maintain ▇▇▇▇▇▇▇▇▇▇▇▇’▇ Tract III facilities area beyond the end of the current projected Tract III production to provide the means for future production should market conditions warrant. Therefore, if ▇▇▇▇▇▇▇▇▇▇▇▇ exercises its option to lease hereunder, the Tract III Lease shall be amended to provide that ▇▇▇▇▇▇▇▇▇▇▇▇ shall have the

In addition, ▇▇▇▇▇▇▇▇▇▇▇▇ will provide One Hundred Twenty-Five Thousand Dollars and 0/100 cents ($125,000.00) to the Crow Tribe to help fund this project. Said fund shall be available thirty (30) days after the date upon which final approval of this Exploration Agreement is granted by the Secretary. At the Tribe’s option and request at any time thereafter, the remaining balance of the fund shall be paid directly to the Tribe.

SECTION 8 SELECTION OF MINING AREA

     8.1 Mining Tract Designation. On or before the Exercise Date, ▇▇▇▇▇▇▇▇▇▇▇▇ shall select, from the Prospect Area, the Mining Area. Selection of the Mining Area shall not itself constitute exercise of the option, and the Mining Area may be amended by ▇▇▇▇▇▇▇▇▇▇▇▇ prior to the Exercise Date.

     8.2 Selection Notice. ▇▇▇▇▇▇▇▇▇▇▇▇ shall select the Mining Area by delivering to the Crow Tribe written notice, in the manner set forth herein, providing the legal description of the tract selected. The mining tract described in the notice shall constitute the Mining Area. The Mining Area shall be identified and by addendum attached to the Coal Lease.

SECTION 9 COAL LEASE

The parties agree to cooperate to seek approval of all terms of this Exploration Agreement and Coal Lease by the Secretary as expeditiously as possible. Approval of the Coal Lease is subject to the limitations in Section 21.6.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     9.2 Effective Date of Lease. In the event ▇▇▇▇▇▇▇▇▇▇▇▇ elects to exercise its option to lease, the Coal Lease shall take effect thirty (30) days following ▇▇▇▇▇▇▇▇▇▇▇▇’▇ notice of its election to lease.

     9.3 Limitation of Mining Area. Notwithstanding any provision in this Exploration Agreement or the Coal Lease, any grant of rights from the Crow Tribe to ▇▇▇▇▇▇▇▇▇▇▇▇ to use or lease land, or to explore for and/or mine Coal is limited to Tribal Land and Tribal Coal. To the extent there is other land and/or Coal located in the Prospect Area and/or the Mining Area, ▇▇▇▇▇▇▇▇▇▇▇▇ shall be responsible for obtaining any necessary right to enter, explore for, and mine Coal on said land or to use and occupy said land, including the acquisition of any necessary surface rights.

     9.4 Acreage Under Lease. Lessee currently leases Coal owned by Lessor outside the boundaries of the Crow Reservation pursuant to the terms of the Tract III lease. Lessee may identify and lease a Mining Area in excess of 2,560 acres, but not more than 3,400 acres, in a single, reasonably compact block. Approval of the Exploration Agreement and Coal Lease shall constitute consent of the Crow Tribe and approval by the Secretary of the Interior, pursuant to applicable law (including 25 C.F.R. §211.25) of: (a) Lessee holding both the Tract III lease and the Coal Lease; and (b) Lessee leasing more than 2,560 acres, but not more than 3,400 acres under the Coal Lease.

SECTION 10 ACQUISITION OF SURFACE RIGHTS

     10.1 The parties recognize that Exploration Rights and Mining Activities will require acquisition of surface rights and/or payment for use and/or damage to surface owners. The parties also recognize that without the ability to conduct Mining Activities in the Mining Area, the Crow Tribe will be unable to realize financial returns of significant benefit to the Crow people.

     10.2 ▇▇▇▇▇▇▇▇▇▇▇▇ will be solely responsible for the cost of paying surface property owners for interests acquired, including grants of ownership, easements, or leases, and for payment of any loss of use or surface damage incurred.

     10.3 The Crow Tribe will cooperate and reasonably assist ▇▇▇▇▇▇▇▇▇▇▇▇ in gaining access to the surface as required to conduct Mining Activities. The Crow Tribe acknowledges that, according to the law, custom, and usage of the Crow Tribe, it has the right, particularly within the boundaries of the Crow Reservation, but also elsewhere, to use and disturb the surface and subsurface of lands, including lands owned by others, to explore for and evaluate mineral deposits, to extract minerals owned by the Crow Tribe, and to convey these rights to a mineral lessee, subject only to the obligation of the Crow Tribe, or the mineral lessee as the case may be, to compensate the property owner for any loss of use or damage to the property. The Crow Tribe agrees to fully support ▇▇▇▇▇▇▇▇▇▇▇▇’▇ efforts in accord with this principle, to obtain such surface rights as may be required to conduct Mining Activities under this Exploration Agreement, or to enforce said right to mine subject to said obligation to reasonably compensate surface owners for loss of use and damage to property.

     10.4 If ▇▇▇▇▇▇▇▇▇▇▇▇’▇ acquisition of surface title within the Crow Reservation would otherwise be prevented as a practical matter by the operation of Section 2 of the 1920 Crow Allotment Act, ▇▇ ▇▇▇▇. ▇▇▇, ▇▇▇, and initial acquisition of such lands in the name of the Crow Tribe would lawfully avoid the impediment, the Tribe agrees to cooperate with ▇▇▇▇▇▇▇▇▇▇▇▇ by taking title to (and, as applicable, exchanging) such lands as are necessary for the purposes of this Agreement in its name and subject to ▇▇▇▇▇▇▇▇▇▇▇▇’▇ rights to use and possess them or to use them for exchange purposes pursuant to Sections 16.2 and 16.3. Nothing in this Agreement shall affect any rights of individual Crow allottees or their heirs or successors arising under Section 2.

▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇

     11.1 Suspension of Obligations. In the event of Force Majeure, as defined in this section, the obligations of ▇▇▇▇▇▇▇▇▇▇▇▇ pursuant to this Exploration Agreement and the documents executed pursuant to this Exploration Agreement, including deadlines for exercising options, shall be suspended, and the term of this Exploration Agreement and all time periods provided for herein shall be extended during the period of Force Majeure, but for no longer period, except as otherwise provided by this Exploration Agreement. However, this provision shall not apply to the settlement with MMS addressed in Section 4.

     11.2 Definition. The term “Force Majeure”, as used in this Exploration Agreement, means any cause beyond the control of ▇▇▇▇▇▇▇▇▇▇▇▇, including, but not limited to: acts of God, labor disputes, insurrections, riots, labor or material shortages, break downs of or damage to equipment or facilities, interruption of transportation of Coal, (including rail car shortages), embargoes, fires, explosions, floods, litigation of any nature preventing ▇▇▇▇▇▇▇▇▇▇▇▇ from exercising any rights outlined in this Exploration Agreement, the elements, casualties not attributable to ▇▇▇▇▇▇▇▇▇▇▇▇, an administrative delay in a governmental agency (including Tribal Government), which is not caused by ▇▇▇▇▇▇▇▇▇▇▇▇’▇ action, newly enacted or mandatory legislation or administrative regulations or changes in the interpretation thereof, orders of civil or military authority or of anybody having jurisdiction over the parties, the Prospect Area or the Mining Area, and extraordinary circumstances not attributable to and not reasonably foreseeable by a reasonably prudent operator, whether such situations affect ▇▇▇▇▇▇▇▇▇▇▇▇ directly or by reason of their effect on a subsidiary, customer, contractor, shipper, or supplier, which wholly or partly prevent the exercise of the Exploration Rights or the mining or delivery of Coal at a reasonable profit.

          The examples enumerated above are by way of example, and not limitation. Force Majeure shall not include any condition arising out of business risks such as fluctuations in prices, sales, or costs, including costs of compliance with requirements for environmental protection; commonly experienced delays in delivery of supplies or equipment; or inability to obtain sufficient sales.

     11.3 Mitigation. ▇▇▇▇▇▇▇▇▇▇▇▇ shall diligently attempt to remedy, as soon as possible, any Force Majeure and to mitigate its effects on the implementation of this Exploration Agreement

and on the payments due the Crow Tribe hereunder; provided, that nothing contained herein shall require the settlement of strikes, lockouts, or other labor difficulties by ▇▇▇▇▇▇▇▇▇▇▇▇ contrary to its wishes, and the disposition or manner of handling or remedying any and all such labor difficulties is hereby expressly acknowledged to be entirely within the discretion of ▇▇▇▇▇▇▇▇▇▇▇▇.

     11.4 Procedures. If a period of Force Majeure is incurred, ▇▇▇▇▇▇▇▇▇▇▇▇ will notify the Crow Tribe within thirty (30) days from the beginning of such period of Force Majeure. The notice will include descriptions of the circumstances that prevent ▇▇▇▇▇▇▇▇▇▇▇▇’▇ performance and ▇▇▇▇▇▇▇▇▇▇▇▇’▇ plans and efforts to remedy or mitigate the Force Majeure, and an estimate of the expected duration of the period of Force Majeure. When the period of Force Majeure has ended, ▇▇▇▇▇▇▇▇▇▇▇▇ will also notify the Crow Tribe. Notice of the commencement of and cessation of Force Majeure periods will be given to the Crow Tribe in writing in accordance with provision 25.3 of this Exploration Agreement. Notice shall also be given to the Regional Director and to the Tribal Attorney.

SECTION 12 CROW REPRESENTATIVES

     Authorized Representative. Crow Tribal Chairperson, who is recognized as such by the BIA, or the said Chairperson’s designee (“Designated Official”), shall be the sole party authorized to deal with ▇▇▇▇▇▇▇▇▇▇▇▇ on any matters related to this Exploration Agreement, excluding regulatory matters and any action taken or authorized by the Tribal Chairperson or the Designated Official shall be deemed to be action taken or authorized by the Crow Tribe unless the authority of the Tribal Chairperson or the Designated Official has been called into question or otherwise been diminished or withdrawn by a properly adopted Tribal resolution delivered to ▇▇▇▇▇▇▇▇▇▇▇▇. ▇▇▇▇▇▇▇▇▇▇▇▇ may otherwise rely upon the authority of the Tribal Chairperson or the Designated Official in conducting any transactions, negotiations, or dealings involving the Crow Tribe, to the full extent of the Chairperson’s powers as head of the Executive Branch of the Crow Tribal Government as provided in Article IV of the Constitution and Bylaws of the Crow Tribe.

SECTION 13 EMPLOYMENT STANDARDS

     Employment Rights. Tribal employment rights are provided in Article 36 of the Coal Lease.

SECTION 14 ASSIGNMENT

     14.1 Assignment of Rights. Each right and obligation hereunder shall extend to and be binding upon, and every benefit hereof shall inure to the heirs, executors, administrators, successors, or assigns of the respective parties.

     14.2 Restriction on Assignment. ▇▇▇▇▇▇▇▇▇▇▇▇ agrees not to assign this Exploration Agreement, by an operating agreement or otherwise, not to sublet any portion of the lands under this Exploration Agreement except with the approval of the Crow Tribe and the Secretary, provided, however, such approval shall not be unreasonably withheld. It is further provided such approval

shall not be required in the event the assignment or sublease is to an Operating Subsidiary of ▇▇▇▇▇▇▇▇▇▇▇▇. ▇▇▇▇▇▇▇▇▇▇▇▇ shall, however, provide notice of such assignment to the Crow Tribe, the Tribal Attorney, and the Regional Director.

SECTION 15 CROW REGULATION

     15.1 Recognition of Tribal Sovereignty. ▇▇▇▇▇▇▇▇▇▇▇▇ recognizes the sovereignty of the Crow Tribe as established by treaty and recognized by federal law. The parties recognize the Crow Tribe, as a sovereign, is concerned with the protection of the health and general welfare of the Crow Tribe and its members, the quality of the environment, the protection, and conservation of tribal resources as well as concerns for the Crow Tribe’s unique cultural interests. The rights provided by this Section 15 are in addition to, and do not diminish, the rights provided in Section 18.

     15.2 Tribal Recognition of Competitive Nature of Mining. The Crow Tribe recognizes the competitive nature of mining and the need for Crow Tribal Coal to be competitive in the marketplace with other Coal mines located within and without Montana. The Crow Tribe also recognizes the Coal mined from the property covered by this Exploration Agreement will compete with low-cost incremental Coal production from existing operations, including non-tribal operations.

     15.3 Notification of Increased Government Costs. The Crow Tribe agrees that while it may adopt laws or regulations that affect the conduct of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ business and exploration and Mining Activities pursuant to this Exploration Agreement, such laws or regulations will not be effective, as to ▇▇▇▇▇▇▇▇▇▇▇▇, until one hundred and twenty (120) days after ▇▇▇▇▇▇▇▇▇▇▇▇ has been provided with a copy of such regulation or law. ▇▇▇▇▇▇▇▇▇▇▇▇ shall then have the right to determine whether the law results in any increased governmental costs to ▇▇▇▇▇▇▇▇▇▇▇▇.

	a.		Definition. For purposes of this Exploration Agreement, “Governmental Costs” shall include all externally imposed costs on ▇▇▇▇▇▇▇▇▇▇▇▇, including, but not limited to, costs incurred by an Operating Subsidiary and other costs associated with Mining Activities (excluding the costs of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ regular staff required for reporting to the Crow Tribe as a government), whether imposed by the Crow Tribe, the United States, or some other governmental entity.
	b.		Governmental Costs, as used herein, shall not include state, county, local, or tribal taxes, which are addressed elsewhere in this Exploration Agreement.

     15.4 Objection Procedure. If ▇▇▇▇▇▇▇▇▇▇▇▇ determines the new law or regulation will increase ▇▇▇▇▇▇▇▇▇▇▇▇’▇ total current Governmental Costs, ▇▇▇▇▇▇▇▇▇▇▇▇ shall notify the Crow Tribe, in writing, detailing the basis of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ belief. ▇▇▇▇▇▇▇▇▇▇▇▇ and the Crow Tribe shall thereafter meet within thirty (30) days after the Crow Tribe’s receipt of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ notice to discuss the matter. If, after that meeting, ▇▇▇▇▇▇▇▇▇▇▇▇ maintains its position and the Crow Tribe does not amend or modify the Tribal Law to remove ▇▇▇▇▇▇▇▇▇▇▇▇’▇ objection, ▇▇▇▇▇▇▇▇▇▇▇▇ may seek arbitration regarding such law or regulation and its economic impact on ▇▇▇▇▇▇▇▇▇▇▇▇.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     15.5 Effect of Arbitrator’s Determination. If the arbitrators rule that the law does not increase ▇▇▇▇▇▇▇▇▇▇▇▇’▇ Governmental Costs, then ▇▇▇▇▇▇▇▇▇▇▇▇ shall comply with such law, unless otherwise provided for herein, including Section 18. If the arbitrators determine the new law or regulation results in an increase in Governmental Costs, then ▇▇▇▇▇▇▇▇▇▇▇▇ shall comply with the new law or regulation but the Crow Tribe shall, at its option, either subsidize the increased Governmental Costs through a tribal tax credit or waive the applicability of the new law or regulation to the extent it results in ▇▇▇▇▇▇▇▇▇▇▇▇’▇ Governmental Costs.

          If the arbitrators have not ruled within the one hundred and twenty (120) day period prior to the new tribal law or regulation taking effect, ▇▇▇▇▇▇▇▇▇▇▇▇ will comply with the new law or regulation as provided above until a ruling is made, provided, however, that in the event the arbitrators subsequently rule that the tribal law under review causes the total Governmental Costs of mining Crow Coal to increase, then ▇▇▇▇▇▇▇▇▇▇▇▇ shall be entitled to recover the difference in such costs incurred from the end of the one hundred and twenty day (120) period provided for above until the date the arbitrators’ ruling goes into effect. Such recovery shall be paid by the Crow Tribe by giving ▇▇▇▇▇▇▇▇▇▇▇▇ a deduction in tribal taxes due or to become due from ▇▇▇▇▇▇▇▇▇▇▇▇.

     15.6 Arbitrators Standard of Review. In determining whether the tribal law under review causes the Governmental Costs of mining Crow Coal to increase, the arbitrators shall compare the Governmental Costs applicable to mining under this Exploration Agreement and the Coal Lease prior to enactment to said Governmental Costs after enactment. Such costs shall include, but not be limited to, fees, operating expenses, safety requirements and reclamation costs. In making this comparison, the arbitrators shall take into account all relevant factors they consider reasonable and necessary to permit a valid comparison. In addition, the arbitrator may consider any savings or reduction in Governmental Costs of mining Crow Coal which have resulted from the passage of other tribal laws, and those savings shall be utilized as offsets in considering the Governmental Costs associated with the tribal law under review.

     15.7 Prohibition Against Regulatory Takings. While making no representations as to the quality, quantity, or location of any Coal reserves subject to this Exploration Agreement, the Crow Tribe agrees it will take no action which precludes ▇▇▇▇▇▇▇▇▇▇▇▇ from mining Crow Coal covered by this Exploration Agreement where such Coal could otherwise be mined under state or federal law, nor will the Crow Tribe enact, as to ▇▇▇▇▇▇▇▇▇▇▇▇, any law, ordinance, or regulation which would result in a regulatory taking of the rights and permits granted to ▇▇▇▇▇▇▇▇▇▇▇▇ under this Exploration Agreement. The Crow Tribe further agrees not to unreasonably withhold or delay any licenses, permits, or other concurrences required by ▇▇▇▇▇▇▇▇▇▇▇▇ pursuant to any law enacted by the Crow Tribe.

     15.8 Procedure. Arbitration shall be conducted in accord with Section 26, except as otherwise provided in this section.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

SECTION 16 TRIBAL LAND

     16.1 Conveyance of Tribal Land. Notwithstanding any provision of this Exploration Agreement or the Coal Lease to the contrary, no lease of coal or option to lease by the Crow Tribe provided for herein, shall be construed by any court or regulatory agency, for any purpose, as a conveyance of Tribal Land in fee. Any such conveyance shall be considered a conveyance of a possessory interest only, and shall in no way be construed to divest the Crow Tribe of its jurisdiction over its land and activities occurring thereon. Except as expressly and unequivocally provided in this Exploration Agreement and Coal Lease (including, without limitation, the limited waivers of sovereign immunity contained therein), the Crow Tribe retains all attributes of its sovereignty and jurisdiction over the lands encumbered by this Exploration Agreement or any right-of-way granted hereunder, and over any activities occurring thereon.

     16.2 Conveyance of Acquired Property. ▇▇▇▇▇▇▇▇▇▇▇▇ recognizes the Crow Tribe’s interest in obtaining title to property it may acquire within the boundaries of the Crow Reservation as part of its South Extension Project. ▇▇▇▇▇▇▇▇▇▇▇▇ agrees to convey to the Crow Tribe title to any property interest acquired within the boundary of the Crow Reservation pursuant to the Coal Lease at the conclusion of Mining Activities. ▇▇▇▇▇▇▇▇▇▇▇▇ shall retain the exclusive and entire right to use and possession of properties within the lease boundaries for the duration of its Mining Activities, including reclamation activities (through final bond release).

     16.3 Property Acquired to Trade. This provision will not prevent ▇▇▇▇▇▇▇▇▇▇▇▇ from acquiring property within the boundaries of the Crow Reservation for the purpose of swapping or trading for other property, to allow ▇▇▇▇▇▇▇▇▇▇▇▇ to acquire title to surface within the Mining Area. Property acquired by ▇▇▇▇▇▇▇▇▇▇▇▇ for that purpose, and eventually used for that purpose, shall not be conveyed to the Crow Tribe. Further, to facilitate acquisition of property needed for Mining Activities, ▇▇▇▇▇▇▇▇▇▇▇▇ may encumber any property it acquires within the Crow Reservation or any property acquired by it for or in the name of the Crow Tribe with access road easements in favor of ▇▇▇▇▇▇▇▇▇▇▇▇ (for Mining Activities) or private owners as may be needed to arrange land swaps or purchases, for acquisition by ▇▇▇▇▇▇▇▇▇▇▇▇ of surface rights needed for Mining Activities. ▇▇▇▇▇▇▇▇▇▇▇▇ will not increase the number of acres owned on the Crow Reservation in fee by non-tribal members.

SECTION 17 TRIBAL TAXES

     17.1 Tribal Severance and Gross Proceeds Taxes. The parties recognize the economic difficulties that will be encountered in developing a new mine in the proposed Mining Area which will be economically competitive in the marketplace, and that taxes on Coal mined hereunder have a negative effect on ▇▇▇▇▇▇▇▇▇▇▇▇’▇ ability to market Tribal Coal and maximize the Crow Tribe’s royalties and ▇▇▇▇▇▇▇▇▇▇▇▇’▇ profits. The parties further recognize this Exploration Agreement and the Coal Lease include provisions which will assist in making Crow Coal produced under the Exploration Agreement more marketable. Thus, except as otherwise provided in this Exploration Agreement or the Coal Lease, the parties hereto agree the activities of ▇▇▇▇▇▇▇▇▇▇▇▇ on the Crow Reservation pursuant to this Exploration Agreement shall only be subject to the Crow Tribe severance tax and gross proceeds tax calculated as provided in the Coal Lease and as further limited by its terms.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     17.2 Exclusion of Additional Taxes. It is the intent of the Crow Tribe that the taxes provided for in this section and the Coal Lease shall be in lieu of all other ad valorem real or personal property taxes, or other taxes of any kind or character, including sales taxes, resource indemnity trust taxes, real, personal, or business property taxes, or income taxes the Crow Tribe might otherwise be empowered to levy against ▇▇▇▇▇▇▇▇▇▇▇▇.

     17.3 Preemption. It is the intent of the parties that the taxes imposed by the Crow Tribe will preempt all state and local taxes, since it is the finding and conclusion of the parties hereto that any additional or dual taxes will place the Coal produced under this Exploration Agreement and Coal Lease at a competitive disadvantage in the marketplace, thus frustrating the Crow Tribe’s efforts to market Crow Coal and improve the Crow Reservation’s economy. In particular, the parties acknowledge ▇▇▇▇▇▇▇▇▇▇▇▇ is unwilling to enter into this Exploration Agreement and Coal Lease without the tax incentives and protections provided herein and in the Coal Lease, and that Coal cannot be mined profitably if ▇▇▇▇▇▇▇▇▇▇▇▇ is required to pay dual state and tribal taxes.

SECTION 18 JURISDICTIONAL DISPUTES

     If ▇▇▇▇▇▇▇▇▇▇▇▇ should, in good faith, question any tribal law or regulation on the basis the Crow Tribe does not have jurisdiction to pass such law, ▇▇▇▇▇▇▇▇▇▇▇▇ shall, subject to the other provisions of this Exploration Agreement, comply with such tribal law or regulation where there is no conflicting federal law, and such compliance shall continue until there is a determination by a court of competent jurisdiction that the Crow Tribe lacks jurisdiction to enforce such law. If there exists a conflict between the tribal law or regulation and a law or regulation of the United States or the state of Montana, ▇▇▇▇▇▇▇▇▇▇▇▇ shall comply with the tribal law unless ▇▇▇▇▇▇▇▇▇▇▇▇ obtains an opinion of counsel which provides ▇▇▇▇▇▇▇▇▇▇▇▇ with a good faith basis for believing that said law or regulation is preempted by conflicting state or federal law and that compliance with the conflicting state or federal law or regulation is appropriate. In such a situation, ▇▇▇▇▇▇▇▇▇▇▇▇ need only comply with the conflicting state or federal law or regulation until such time as a court of competent jurisdiction determines the state or federal law has no application to ▇▇▇▇▇▇▇▇▇▇▇▇. Thereafter, ▇▇▇▇▇▇▇▇▇▇▇▇ shall, subject to other provisions of this Exploration Agreement, comply with the applicable tribal law or regulation.

SECTION 19 LIMITED WAIVER OF SOVEREIGN IMMUNITY

     The Crow Tribe specifically and unequivocally waives its sovereign immunity from suit and hereby consents to being named as a party in any litigation between ▇▇▇▇▇▇▇▇▇▇▇▇, an Operating Subsidiary and the Crow Tribe involving the construction, execution, interpretation, validity, enforcement, performance, or any dispute arising under this Exploration Agreement and the Coal Lease, including any dispute concerning the rights, responsibilities, and obligations of the parties hereto relating to the mining of Crow Coal under this Exploration Agreement and the Coal Lease. It is agreed that this waiver of sovereign immunity is limited and extends only to ▇▇▇▇▇▇▇▇▇▇▇▇ and an Operating Subsidiary and to no other parties, and that the waiver is further limited to only those matters referenced in this provision.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     This waiver shall be effective such that both parties shall comply with the binding arbitration provisions of the Exploration Agreement and Coal Lease and either party may have recourse to federal court to fully enforce the parties’ agreement to arbitrate and the arbitration result pursuant to the Federal Arbitration Act found at 9 U.S.C. § 1, et seq.

     This waiver of sovereign immunity is based upon the Crow Tribe’s opinion, belief and considered finding that the assertion of the Crow Tribe’s sovereign immunity in any dispute involving ▇▇▇▇▇▇▇▇▇▇▇▇ concerning this Exploration Agreement or the Coal Lease would be inappropriate. The parties expressly recognize this waiver shall not extend to or apply to any claim which might be brought against the Crow Tribe for punitive damages. Further, the parties expressly recognize this waiver shall not permit or authorize the sale or transfer of any property held by the United States in trust for the Crow Tribe. Except for an award of costs and attorneys’ fees of or for any arbitration proceedings, the Crow Tribe’s monetary liability resulting from any dispute arising under the referenced agreements and the waiver of sovereign immunity herein is limited to an award against the Tribe of offsets or withholding of future royalties and taxes otherwise payable by ▇▇▇▇▇▇▇▇▇▇▇▇ to the Crow Tribe, and/or injunctive relief providing for enforcement of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ right to explore, lease, and mine according to the referenced agreements.

     A true and correct copy of Crow Tribal Legislative Act No. CLB 0402, enacted February 10, 2004, and approved February 12, 2004, approving this limited waiver of sovereign immunity as to matters arising in conjunction with this Exploration Agreement and Coal Lease, is attached hereto as Exhibit “D.”

SECTION 20 AUTHORIZATIONS

     20.1 Crow Tribe Authorizations. The Crow Tribe warrants the execution of this Exploration Agreement has been validly authorized by the Crow Tribal Legislature and Executive Branch and that the execution by the Chairman of the Crow Tribe has been duly authorized and approved.

     20.3 Corporate Existence of ▇▇▇▇▇▇▇▇▇▇▇▇. ▇▇▇▇▇▇▇▇▇▇▇▇ is a corporation duly incorporated, validly existing, and in good standing under the laws of the state of Delaware, is registered to do business in Montana, and its registration status in Montana is active and in good standing. ▇▇▇▇▇▇▇▇▇▇▇▇ has full corporate power and authority to execute and deliver this Agreement and to perform its obligations hereunder.

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

     20.4 Authority. The execution and delivery by ▇▇▇▇▇▇▇▇▇▇▇▇ of this Agreement, and the performance by ▇▇▇▇▇▇▇▇▇▇▇▇ of its obligations hereunder, have been duly and validly authorized by ▇▇▇▇▇▇▇▇▇▇▇▇ and no other corporate action on the part of ▇▇▇▇▇▇▇▇▇▇▇▇ is necessary. Upon execution by the President of ▇▇▇▇▇▇▇▇▇▇▇▇, and delivery by ▇▇▇▇▇▇▇▇▇▇▇▇, and upon due execution by the Crow Tribe, and by governmental approval as provided herein, this Agreement shall be valid and binding upon ▇▇▇▇▇▇▇▇▇▇▇▇ and enforceable against ▇▇▇▇▇▇▇▇▇▇▇▇ in accordance with its terms.

     20.5 Opinion of Counsel of ▇▇▇▇▇▇▇▇▇▇▇▇. The legal counsel of ▇▇▇▇▇▇▇▇▇▇▇▇ has simultaneously, with the execution of this Exploration Agreement, delivered to the Crow Tribe an opinion that this Exploration Agreement is duly authorized and validly executed by ▇▇▇▇▇▇▇▇▇▇▇▇, which opinion is attached hereto as Exhibit F.

SECTION 21 APPROVAL BY SECRETARY AND BY THE TRIBE

     21.1 Approval by Crow Tribe. The Crow Tribe shall approve this and all attached and related exhibits and agreements in the manner provided in Section 5.1.

     21.2 Approval by the Secretary. Approval by the Secretary is required. ▇▇▇▇▇▇▇▇▇▇▇▇ and the Crow Tribe shall cooperate in seeking prompt approval of this Exploration Agreement and the Coal Lease and all other agreements and exhibits attached or incorporated therein. Failure to obtain approval of the Secretary shall result in cancellation of this Agreement or related agreements as provided herein. It is understood that after approval by the Crow Tribe, further approval of the MMS Settlement Agreement by the Secretary (including the MMS) shall be independent from the Secretary’s approval of the remainder of the Exploration and Option to Lease Agreement.

     21.3 Deadline for Secretarial Approval. The Secretary shall approve the agreements as provided in Section 21.2 within six (6) months of the date of the payment of the sum described in Section 5.1. If said approval does not occur within six (6) months, ▇▇▇▇▇▇▇▇▇▇▇▇ may, at its sole option, cancel this and all related agreements or extend the time provided for such secretarial approval. The parties anticipate and request that the separate approvals by the Secretary of the MMS Settlement Agreement (Exhibit C) and the Prospecting Permit referred to in Section 2.3 occur as soon after the Tribe’s approval of this Agreement as is reasonably practical.

     21.4 Payments Prior to Secretarial Approval. The payment described in Section 5.1 shall be made upon the approval described therein, but shall be refunded as provided therein if the Secretary does not provide approval as provided in this Section 21. The payment described in Section 5.2 shall not be refunded to ▇▇▇▇▇▇▇▇▇▇▇▇ if the Secretary does not provide approval of the Exploration Agreement and Coal Lease, as long as the MMS Settlement Agreement referenced in Section 5.2 has been fully approved according to its separate terms.

     21.5 Approval of This and Related Agreements. Approval of this Exploration Agreement by the Secretary, the Crow Tribe, and ▇▇▇▇▇▇▇▇▇▇▇▇ constitutes approval of all other agreements and exhibits attached or incorporated herein, specifically including the Coal Lease, and

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

further secretarial approval of those agreements shall be unnecessary. It is the finding of the Secretary, by the approval of this Exploration Agreement, that such approval is in the best interests of the Crow Indian Tribe, and any regulations that are, in any way, inconsistent with the rights granted herein, are waived.

     21.6 Approval of Agreements Does Not Constitute Permission to Mine. The Secretary’s approval of the Exploration Agreement and the Coal Lease do not constitute approval or authorization of any surface disturbing activities from an environmental perspective. All parties acknowledge that future NEPA (National Environmental Policy Act, 42 U.S.C. § 4321, et seq.) compliance will be necessary for exploration/development, drilling, and mining. it is contemplated that future NEPA compliance will involve environmental analysis satisfactory to the BIA, BLM, and OSM prior to authorization and permitting for mining. Therefore, the approval provided by this section does not constitute issuance or approval of any required exploration, drilling, or mining permit or plan.

SECTION 22 FEDERAL TRUST AND SUPERVISION

     22.1 Federal Trust Responsibilities. While the mineral interests and certain lands covered by this Exploration Agreement and the Coal Lease are in trust or restricted status, all of ▇▇▇▇▇▇▇▇▇▇▇▇’▇ obligations under this Exploration Agreement and the Coal Lease, and the obligations of its sureties, are to the United States as well as to the Crow Tribe, and all payments to the Crow Tribe provided herein or therein will be made to the Superintendent for the use and benefit of the Crow Tribe, and payments shall be made according to applicable federal regulations. Nothing contained in this Exploration Agreement or the Coal Lease shall operate to delay or prevent a termination of Federal trust responsibilities with respect to the lands covered by this Exploration Agreement or the Coal Lease; however, such termination shall not serve to abrogate this Mining Area Agreement or the Coal Lease.

     22.2 Relinquishment of Supervision. Should the Secretary, at any time during the term of this Exploration Agreement or the Coal Lease, relinquish supervision as to all or part of the lands covered by this Exploration Agreement or the Coal Lease, the relinquishment shall not bind ▇▇▇▇▇▇▇▇▇▇▇▇ until it has received from the Secretary thirty (30) days written notice of such relinquishment. After notice of relinquishment has been received, this Exploration Agreement and the Coal Lease are subject to the following further conditions:

	a.		Payments. All payments payable after such notice attributable to tribally owned Coal relinquished from supervision shall be paid directly to the Crow Tribe.
	b.		Effect on Bonding Requirements. If at the time supervision is relinquished by the Secretary as to all the tribally-owned Coal within the Mining Area or Facilities Area, ▇▇▇▇▇▇▇▇▇▇▇▇ has made all payments due under this Exploration Agreement or the Coal Lease and has fully performed all obligations to be performed up to the time of such relinquishment, then any

Confidential materials omitted and filed separately with the SEC. Asterisks denote omissions.

bond given to secure the performance of this Exploration Agreement or the Coal Lease and on file in the office of the Bureau of Indian Affairs shall be cancelled and released.

If at the time of any such relinquishment of supervision by the Bureau, ▇▇▇▇▇▇▇▇▇▇▇▇ has not performed all obligations imposed upon it hereunder or under the Coal Lease, ▇▇▇▇▇▇▇▇▇▇▇▇ shall file with the Crow Tribe a bond (“New Bond”) in favor of the Crow Tribe in a principal amount equal to that immediately theretofore in force with the Bureau of Indian Affairs and conditioned upon the performance by ▇▇▇▇▇▇▇▇▇▇▇▇ of those undertakings provided for in the bond (“Old Bond”) immediately theretofore in force with the Bureau. The new Bond shall be continued in force until ▇▇▇▇▇▇▇▇▇▇▇▇ performs all obligations secured thereby, provided, however, that such New Bond shall not be required until the Old Bond filed with the Bureau has been released.

SECTION 23 DEFAULT

     23.1 Conditions of Default. The breach by ▇▇▇▇▇▇▇▇▇▇▇▇ or the Crow Tribe of any of the terms and conditions of this Exploration Agreement of the Coal Lease shall constitute a default hereunder.

     23.2 Default Procedures. If a party believes a default has occurred, it may notify the other party in writing of such alleged default, specifying its nature. The parties shall meet within thirty (30) days to attempt to agree in whether there is such a default and, if so, on an appropriate remedy. If the parties are unable to agree, the complaining party may, within sixty (60) days after giving notice of such default, begin arbitration proceedings as provided for in this Exploration Agreement.

	a.		Non-Monetary Default. If the arbitrator decides that a non-monetary default has occurred, the defaulting party shall have one hundred and eighty (180) days after receipt of the decision finding a default to cure such default, provided, however, such one hundred and eighty (180) day period shall be extended to include any period during which the defaulting party prosecutes with diligence and to completion an attempt to cure such non-monetary default, if it cannot be cured within one hundred and eighty (180) days.
	b.		Monetary Default. If the arbitrator decides a monetary default has occurred, the defaulting party shall have sixty (60) days after receipt of the decision finding such a default to cure that default. If such default is not cured as required, the complaining party, in addition to seeking other remedies available at law, may ask the arbitrator to impose penalties or sanctions; provided, any sanction that involves termination of all or part of this Exploration Agreement or the Coal Lease because such uncured default

shall be effective only after a determination by the arbitrators that the defaulting party has acted willfully in failing to cure the default.

     23.3 Remedies for ▇▇▇▇▇▇▇▇▇▇▇▇’▇ Default. If default by ▇▇▇▇▇▇▇▇▇▇▇▇ is not cured as required by the arbitrators, the Crow Tribe may request, and the arbitrators may order, a termination of this Exploration Agreement or the Coal Lease as to the Prospect Area or the Mining Area with respect to which the default occurred.

     23.4 Remedies of Secretary. The parties hereto expressly recognize this section does not limit the options of the Secretary, in the exercise of the Secretary’s trust responsibilities, under this Exploration Agreement.

SECTION 24 TERMINATION

     Termination Rights. At any time prior to the effective date of the Coal Lease as provided in Section 9.2 herein, ▇▇▇▇▇▇▇▇▇▇▇▇ may terminate this Exploration Agreement.
