rights-of-way which may be necessary and convenient in the exercise of the rights and privileges granted, subject to the conditions herein provided. 


PART II. TERMS AND CONDITIONS 


Sec.
1. (a) RENTAL RATE – Lessee must pay lessor rental annually and in advance for each acre or fraction thereof during the continuance of the lease at the rate of $3.00 for
each lease year. 


(b)
RENTAL CREDITS – Rental will not be credited against either production or advance royalties for any year. 


Sec.
2. (a) PRODUCTION ROYALTIES – The royalty will be 121/2 percent of the value of the coal as set forth in the regulations. Royalties are due to
lessor the final day of the month succeeding the calendar month in which the royalty obligation accrues. 







 

(b)
ADVANCE ROYALTIES – Upon request by the lessee, the BLM may accept, for a total of not more than 10 years, the payment of advance royalties in lieu of continued
operation, consistent with the regulations. The advance royalty will be based on a percent of the value of a minimum number of tons determined in the manner established by the advance royalty
regulations in effect at the time the lessee requests approval to pay advance royalties in lieu of continued operation. 







Sec.
3. BONDS – Lessee must maintain in the proper office a lease bond in the amount of $ *.
The BLM may require an increase in this amount when additional coverage is determined appropriate. 


*$29,271,000.00



Sec.
4. DILIGENCE – This lease is subject to the conditions of diligent development and continued operation, except that these conditions are excused when operations under the lease
are interrupted by strikes, the elements, or casualties not attributable to the lessee. The lessor, in the public interest, may suspend the condition of continued operation upon payment of advance
royalties in accordance with the regulations in existence at the time of the suspension. Lessee's failure to produce coal in commercial quantities at the end of 10 years will terminate the
lease. Lessee must submit an operation and reclamation plan pursuant to Section [Illegible] of the Act not later than 3 years after lease issuance. 


The
lessor reserves the power to assent to or order the suspension of the terms and conditions of this lease in accordance with, inter alia. Section 39 of the Mineral Leasing Act, 30 U.S.C.
209. 


Sec.
5. LOGICAL MINING UNIT (LMU) – Either upon approval by the lessor of the lessee's application or at the direction of the lessor, this lease will become an LMU or part of an
LMU, subject to the provisions set forth in the regulations. 


The
stipulations established in an LMU approval in effect at the time of LMU approval will supersede the relevant inconsistent terms of this lease so long as the lease remains committed to the LMU. If
the LMU of which this lease is a part is dissolved, the lease will then be subject to the lease terms which would have been applied if the lease had not been included in an LMU. 


Sec.
6. DOCUMENTS, EVIDENCE AND INSPECTION – At such times and in such form as lessor may prescribe, lessee must furnish detailed statements showing the amounts and quality
of all products removed and sold from the lease, the proceeds therefrom, and the amount used for production purposes or unavoidably lost. 


Lessee
must keep open at all reasonable times for the inspection by BLM the leased premises and all surface and underground improvements, works, machinery, ore stockpiles, equipment, and all books,
accounts, maps, and records relative to operations, surveys, or investigations on or under the leased lands. 


Lessee
must allow lessor access to and copying of documents reasonably necessary to verify lessee compliance with terms and conditions of the lease. 



While
this lease remains in effect, information obtained under this section will be closed to inspection by the public in accordance with the Freedom of Information Act (5 U.S.C. 552). 


See.
7. DAMAGES TO PROPERTY AND CONDUCT OF OPERATIONS – Lessee must comply at its own expense with all reasonable orders of the Secretary, respecting diligent operations, prevention
of waste, and protection of other resources. 


Lessee
must not conduct exploration operations, other than casual use, without an approved exploration plan. All exploration plans prior to the commencement of mining operations within an approved
mining permit area must be submitted to the BLM. 


2







 

Lessee
must carry on all operations in accordance with approved methods and practices as provided in the operating regulations, having due regard for the prevention of injury to life, health, or
property, and prevention of waste, damage or degradation to any land, air, water, cultural, biological, visual, and other resources, including mineral deposits and formations of mineral deposits not
leased hereunder, and to other land uses or users. Lessee must take measures deemed necessary by lessor to accomplish the intent of this lease term. Such measures may include, but are not limited to
modification to proposed siting or design of facilities, timing of operations, and specification of interim and final reclamation procedures. Lessor reserves to itself the right to lease, sell, or
otherwise dispose of the surface or other mineral deposits in the lands and the right to continue existing uses and to authorize future uses upon or in the leased lands, including issuing leases for
mineral deposits not covered hereunder and approving easements or rights-of-way. Lessor must condition such uses to prevent unnecessary or unreasonable interference with rights
of lessee as may be consistent with concepts of multiple use and multiple mineral development. 


Sec.
8. PROTECTION OF DIVERSE INTERESTS, AND EQUAL OPPORTUNITY – Lessee must: pay when due all taxes legally assessed and levied under the laws of the State or the United States;
accord all employees complete freedom of purchase; pay all wages at least twice each month in lawful money of the United States; maintain a safe working environment in accordance with standard
industry practices; restrict the workday to not more than 8 hours in any one day for underground workers, except in emergencies; and take measures necessary to protect the health and safety of
the public. No person under the age of 16 years should be employed in any mine below the surface. To the extent that laws of the State in which the lands are situated are more restrictive than
the provisions in this paragraph, then the State laws apply. 


Lessee
will comply with all provisions of Executive Order No. 11246 of September 24, 1965, as amended, and the rules, regulations, and relevant orders of the Secretary of Labor. Neither
lessee nor lessee's subcontractors should maintain segregated facilities. 


Sec.
9. (a) TRANSFERS 



	ý
	This
lease may be transferred in whole or in part to any person, association or corporation qualified to hold
such lease interest.



	o
	This
lease may be transferred in whole or in part to another public body or to a person who will mine the coal
on behalf of, and for the use of, the public body or to a person who for the limited purpose of creating a security interest in favor of a lender agrees to be obligated to mine the coal on behalf of
the public body.



	o
	This
lease may only be transferred in whole or in part to another small business qualified under 13 CFR 121. 



Transfers
of record title, working or royalty interest must be approved in accordance with the regulations. 







(b) RELINQUISHMENT – The lessee may relinquish in writing at any time all rights under this lease or any portion thereof as provided in the regulations. Upon
lessor's acceptance of the relinquishment, lessee will be relieved of all future obligations under the lease or the relinquished portion thereof, whichever is applicable. 


Sec.
10. DELIVERY OF PREMISES, REMOVAL OF MACHINERY, EQUIPMENT, ETC. – At such time as all portions of this lease are returned to lessor, lessee must deliver up to lessor the land
leased, underground timbering, and such other supports and structures necessary for the preservation of the mine workings on the leased premises or deposits and place all workings in condition for
suspension or abandonment. Within 180 days thereof, lessee must remove from the premises all other structures, machinery, equipment, tools, and materials that it elects to or as required by the
BLM. Any such 


3







 



structures,
machinery, equipment, tools, and materials remaining on the leased lands beyond 180 days, or approved extension thereof, will become the property of the lessor, but lessee may
either remove any or all such property or continue to be liable for the cost of removal and disposal in the amount actually incurred by the lessor. If the surface is owned by third parties, lessor
will waive the requirement for removal, provided the third parties do not object to such waiver. Lessee must, prior to the termination of bond liability or at any other time when required and in
accordance with all applicable laws and regulations, reclaim all lands the surface of which has been disturbed, dispose of all debris or solid waste, repair the offsite and onsite damage caused by
lessee's activity or activities incidental thereto, and reclaim access roads or trails. 


Sec.
11. PROCEEDINGS IN CASE OF DEFAULT – If lessee fails to comply with applicable laws, existing regulations, or the terms, conditions and stipulations of this lease, and the
noncompliance continues for 30 days after written notice thereof, this lease will be subject to cancellation by the lessor only by judicial proceedings. This provision will not be construed to
prevent the exercise by lessor of any other legal and equitable remedy, including waiver of the default. Any such remedy or waiver will not prevent later cancellation for the same default occurring at
any other time. 


Sec.
12. HEIRS AND SUCCESSORS-IN-INTEREST – Each obligation of this lease will extend to and be binding upon, and every benefit hereof will inure to, the
heirs, executors, administrators, successors, or assigns of the respective parties hereto. 


Sec.
13. INDEMNIFICATION – Lessee must indemnify and hold harmless the United States from any and all claims arising out of the lessee's activities and operations under this lease.

SEC.
15.    SPECIAL STIPULATIONS –    



In
addition to observing the general obligations and standards of performance set out in the current regulations, the lessee shall comply with and be bound by the following special stipulations. 


These
stipulations are also imposed upon the lessee's agents and employees. The failure or refusal of any of these persons to comply with these stipulations shall be deemed a failure of the lessee to
comply with the terms of the lease. The lessee shall require his agents, contractors and subcontractors involved in activities concerning this lease to include these stipulations in the contracts
between and among them. These stipulations may be revised or amended, in writing, by the mutual consent of the lessor and the lessee at any time to adjust to changed conditions or to correct an
oversight. 


(a)  CULTURAL RESOURCES – (1) Before undertaking any activities that may disturb the surface of the leased lands, the
lessee shall conduct a cultural resource intensive field inventory in a manner specified by the Authorized Officer of the BLM or of the surface managing agency, if different, on portions of the mine
plan area and adjacent areas, or exploration plan area, that may be adversely affected by lease-related activities and which were not previously inventoried at such a level of intensity. The inventory
shall be conducted by a qualified professional cultural resource specialist (i.e., archeologist, historian, historical architect, as appropriate), approved by the Authorized Officer of the
surface managing agency (BLM, if the surface is privately owned), and a report of the inventory and recommendations for protecting any cultural resources identified shall be submitted to the Assistant
Director of the Western Support Center of the Office of Surface Mining, the Authorized Office of the BLM, if activities are associated with coal exploration outside an approved mining permit area
(hereinafter called Authorized Officer), and the Authorized Officer of the surface managing
agency, if different. The lessee shall undertake measures, in accordance with instructions from the Assistant Director, or Authorized Officer, to protect cultural resources on the leased lands. The
lessee shall not commence the surface disturbing activities until permission to proceed is given by the Assistant Director or Authorized Officer. 



(2)  The
lessee shall protect all cultural properties that have been determined eligible to the National Register of Historic Places within the lease area from lease-related activities
until the cultural resource mitigation measures can be implemented as part of an approved mining and reclamation or exploration plan unless modified by mutual agreement in consultation with the State
Historic Preservation Officer. 


(3)  The
cost of conducting the inventory, preparing reports, and carrying out mitigation measures shall be borne by the lessee. 


(4)  If
cultural resources are discovered during operations under this lease, the lessee shall immediately bring them to the attention of the Assistant Director or Authorized Officer, or
the Authorized Officer of the surface managing agency, if the Assistant Director is not available. The lessee shall not disturb such resources except as may be subsequently authorized by the Assistant
Director or Authorized Officer. 


Within
two (2) working days of notification, the Assistant Director or Authorized Officer will evaluate or have evaluated any cultural resources discovered and will determine if any action may
be required to protect or preserve such discoveries. The cost of data recovery for cultural resources discovered during lease operations shall be borne by the lessee unless otherwise specified by the
Authorized Officer of the BLM or of the surface managing agency, if different. 


(5)  All
cultural resources shall remain under the jurisdiction of the United States until ownership is determined under applicable law. 



(b)  PALEONTOLOGICAL RESOURCES – If paleontological resources, either large and conspicuous, and/or of significant
scientific value are discovered during mining operations, the find will be reported to the Authorized Officer immediately. Mining operations will be suspended within 250 feet of said 


7







 



find.
An evaluation of the paleontological discovery will be made by a BLM approved professional paleontologist within five (5) working days, weather permitting, to determine the appropriate
action(s) to prevent the potential loss of any significant paleontological value. Operations within 250 feet of such discovery will not be resumed until written authorization to proceed is issued by
the Authorized Officer. The lessee will bear the cost of any required paleontological appraisals, surface collection of
fossils, or salvage of any large conspicuous fossils or significant scientific interest discovered during the operations. 


(c)  THREATENED and ENDANGERED SPECIES – The lease area may now or hereafter contain plants, animals, or their habitats
determined to be threatened or endangered under the Endangered Species Act of 1973, as amended, 16 U.S.C. 1531 et seq., or that have other special
status. The Authorized Officer may recommend modifications to exploration and development proposals to further conservation and management objectives or to avoid activity that will contribute to a
need to list such species or their habitat or to comply with any biological opinion issued by the Fish and Wildlife Service for the proposed action. The Authorized Officer will not approve any
ground-disturbing activity that may affect any such species or critical habitat until it completes its obligations under applicable requirements of the Endangered Species Act. The Authorized Officer
may require modifications to, or disapprove a proposed activity that is likely to result in jeopardy to the continued existence of a proposed or listed threatened or endangered species, or result in
the destruction or adverse modification of designated or proposed critical habitat. 


The
lessee shall comply with instructions from the Authorized Officer of the surface managing agency (BLM, if the surface is private) for ground disturbing activities associated with coal exploration
on federal coal leases prior to approval of a mining and reclamation permit or outside an approved mining and reclamation permit area. The lessee shall comply with instructions from the Authorized
Officer of the Office of Surface Mining Reclamation and Enforcement, or his designated representative, for all ground-disturbing activities taking place within an approved mining and reclamation
permit area or associated with such a permit. 


(d)    MULTIPLE MINERAL DEVELOPMENT – Operations will not be approved which, in the opinion of the Authorized Officer,
would unreasonably interfere with the orderly development and/or production from a valid existing mineral lease issued prior to this one for the same lands. 


(e)    OIL AND GAS/COAL RESOURCES – The BLM realizes that coal mining operations conducted on Federal coal leases issued
within producing oil and gas fields may interfere with the economic recovery of oil and gas; just as Federal oil and gas leases issued in a Federal coal lease area may inhibit coal recovery. BLM
retains the authority to alter and/or modify the resource recovery and protection plans for coal operations and/or oil and gas operations on those lands covered by Federal mineral leases so as to
obtain maximum resource recovery. 


(f)    RESOURCE RECOVERY AND PROTECTION – Notwithstanding the approval of a resource recovery and protection plan (R2P2) by
the BLM, lessor reserves the right to seek damages against the operator/lessee in the event (i) the operator/lessee fails to achieve maximum economic recovery (MER) (as defined at 43 CFR
3480.0-5(21)) of the recoverable coal reserves or (ii) the operator/lessee is determined to have caused a wasting of recoverable coal reserves. Damages shall be measured on the
basis of the royalty that would have been payable on the wasted or unrecoverable coal. 


The
parties recognize that under an approved R2F2, conditions may require a modification by the operator/lessee of that plan. In the event a coal bed or portion thereof is not to be mined or is
rendered unmineable by the operation, the operator/lessee shall submit appropriate justification to obtain approval by the Authorized Officer to leave such reserves unmined. Upon approval by the
Authorized Officer, such coal beds or portions thereof shall not be subject to damages as described above. Further, nothing in this section shall prevent the operator/lessee from exercising its right
to relinquish all or portion of the lease as authorized by statute and regulation. 


8







 

In
the event the Authorized Officer determines that the R2P2, as approved, will not attain MER as the result of changed conditions, the Authorized Officer will give proper notice to the
operator/lessee as required under applicable regulations. The Authorized Office will order a modification if necessary, identifying additional reserves to be mined in order to attain MER. Upon a final
administrative or judicial ruling upholding such an ordered modification, any reserves left unmined (wasted) under that plan will be subject to damages as described in the first paragraph under this
section. 


Subject
to the right to appeal hereinafter set forth, payment of the value of the royalty on such unmined recoverable coal reserves shall become due and payable upon determination by the Authorized
Officer that the coal reserves have been rendered unmineable or at such time that the operator/lessee had demonstrated an unwillingness to extract the coal. 


The
BLM may enforce this provision either by issuing a written decision requiring payment of the MMS demand for such royalties, or by issuing a notice of non-compliance. A decision or
notice of non-compliance issued by the lessor that payment is due under this stipulation is appealable as allowed by law. 


(g)  PUBLIC LAND SURVEY PROTECTION – The lessee will protect all survey monuments, witness corners, reference monuments,
and bearing trees against destruction, obliteration, or damage during operations on the lease areas. If any monuments, corners or accessories are destroyed, obliterated, or damaged by this operation,
the lessee will hire an appropriate county surveyor or registered land surveyor to reestablish or restore the monuments, corners, or accessories at the same locations, using the surveying procedures
in accordance with the "Manual of Surveying Instructions for the Survey of the Public Lands of the United States." The survey will be recorded, in the
appropriate county records, with a copy sent to the Authorized Officer.
