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

Sec. 2. (a) PRODUCTION ROYALTIES - The royalty shall be 12 1/2 percent of the
value of the coal produced by strip or auger methods and 8 percent of the value
of the coal produced by underground mining methods. The value of the coal shall
be determined as set forth in 43 CFR 3480. 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 lessee, the authorized officer 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

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 shall maintain in the proper office a lease bond in the
amount of $5,000.00. The authorized officer may require an increase in this
amount when additional coverage is determined appropriate.

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 the 10 years shall terminate the lease. If not submitted already, lessee
shall submit an operation and reclamation plan pursuant to Section 7 of the Act
no later than 3 years after the effective date of this lease readjustment.

The lessor reserves the power to assent to or under 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 shall 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

                                                                               3

the LMU. If the LMU of which this lease is a part is dissolved, the lease shall
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 shall 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 shall keep open at all reasonable times for the inspection of any duly
authorized officer of lessor, the leased premises and all surface and
underground improvements, works, machinery, ore stockpits, equipment, and all
books, accounts, maps and records relative to operations, surveys, or
investigations on or under the leased lands.

Lessee shall 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
shall be closed to inspection by the public in accordance with the Freedom of
Information Act (5 U.S.C. 552).

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

Lessee shall 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 shall be submitted to
the authorized officer.

Lessee shall 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 shall
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 shall
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 shall:
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

the health and safety of the public. No person under the age of 16 years shall
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 the
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 shall maintain
segregated facilities.

          association or corporation qualified to hold such lease interest.

     [ ]  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.

     [ ]  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 shall 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
times as all portions of this lease are returned to lessor, lessee shall 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 shall remove from the premises all
other structures, machinery, equipment, tools, and materials that it elects to
or as required by the authorized officer. Any such structures, machinery,
equipment, tools and materials remaining on the leased lands beyond 180 days or
approved extension thereof, shall become the property of the lessor, but lessee
shall either remove any or all such property or shall 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 shall waive the requirement for
removal, provided the third parties do not object to such waiver. Lessee shall,
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

                                                                               5

noncompliance continues for 30 days after written notice thereof, this lease
shall be subject to cancellation by the lessor only by judicial proceedings.
This provision shall 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 shall 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 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 hereto.

Sec. 13. INDEMNIFICATION - Lessee shall 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. 14. SPECIAL STATUTES - This lease is subject to the Federal Water Pollution
Control Act (33 U.S.C. 1151-1175), the Clean Air Act (42 U.S.C. 1857, et. seq.),
and to all other applicable laws pertaining to exploration activities, mining
operations and reclamation, including the Surface Mining Control and Reclamation
Act of 1977 (30 U.S.C. 1201 et. seq.).

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 officer 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.

                                                                               6

(2) The lessee shall protect all cultural resource properties 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 plan
or exploration plan.

(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 surface managing agency
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
surface disturbing activities, the find will be reported to the Authorized
Officer immediately. Surface disturbing activities will be suspended within 250
feet of said 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 of significant scientific interest
discovered during the operations.

(c) 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.

(d) 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.

                                                                               7

(e) 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 royalty that would have been
payable on the wasted or unrecovered coal.

The parties recognize that under an approved R2P2, conditions may require a
modification by the operator/lessee of that plan. In the event a coalbed 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 (AO) to leave such reserves unmined. Upon approval by the
AO, such coalbeds 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 rights to relinquish all or portion of the
lease as authorized by statute and regulation.

In the event the AO determines that the R2P2, as approved, will not attain MER
as the result of changed conditions, the AO will give proper notice to the
operator/lessee as required under application regulations. The AO 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 AO that the coal reserves have been rendered
unmineable or at such time that the operator/lessee has 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 noncompliance. A decision or notice of noncompliance issued by the lessor
that payment is due under this stipulation is appealable as allowed by law.

(f) 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 location, using 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.

                         Period of Liability Terminated

On August 5, 1999, and October 12, 1999, we received documents evidencing the
merger of Cyprus Amax Coal Company into RAG American Coal Company with RAG
American Coal Company as the surviving entity, along with documentation of the
name change from Amax Land Company to RAG Wyoming Land Company. Additionally, we
received qualifications statements for RAG American Coal Company and RAG Wyoming
Land Company.

On August 20, 1999, we received a replacement logical mining unit bond (Numbers
210067-067, KA2990-067, 103198931-067) in the amount of $2,415,000 with RAG
Wyoming Land Company as principal, to provide coverage for Federal coal leases
WYW0317682, WYW78629, and WYW80954 included in the Belle Ayr Mine Logical Mining
Unit (LMU). The limits shared by the sureties are shown below:

Travelers Casualty and Surety Company    103198931-067             $805,000

On October 12, 1999, we received a rider to the above-described bond which
extends coverage of the bond to cover any and all liabilities that may be
outstanding on Bond Number 159015328, with AMAX Land Company as principal, and
National Fire Insurance Company of Hartford as surety.

The merger documents, qualifications statements, replacement bond, and rider
have been examined, found satisfactory, and are accepted effective October 12,
1999.

The period of liability under LMU Bond Number 159015328, with National Fire
Insurance Company of Hartford as surety, and AMAX Land Company as principal, is
hereby terminated effective October 12, 1999, the acceptance date of the
replacement bond.

The records of this office have been changed to reflect that the lessee of
record for Federal coal leases WYW0317682, WYW78629, and WYW80954 is RAG Wyoming
Land Company. We have also changed our records to reflect that RAG Wyoming Land
Company is now the applicant for Federal coal lease application WYW141568 filed
March 20, 1997.

Additionally, RAG Wyoming Land Company has requested that the Belle Ayr Mine LMU
be modified to change the unit operator from AMAX Land Company to RAG Wyoming
Land Company. The LMU is hereby modified to reflect that RAG Wyoming Land
Company is the operator and will be responsible for operations under the LMU in
accordance with the LMU approval document.

lease-related activities. If the authorized officer determines that one is
necessary, the paleontological appraisal shall be conducted by a qualified
paleontologist approved by the authorized officer of the surface managing agency
(BLM if the surface is privately owned), using the published literature and,
where appropriate, field appraisals for determining the possible existence of
larger and more conspicuous fossils of scientific significance. A report of the
appraisal and recommendations for protecting any larger and more conspicuous
fossils of significant scientific interest on the leased lands so identified
shall be submitted to the authorized officer of the surface managing agency (BLM
if the surface is privately owned). When necessary to protect and collect the
larger and more conspicuous fossils of significant scientific interest on the
leased lands, the lessee shall undertake the measures provided in the approval
of the mining and reclamation plan or exploration plan.

(2) The lessee shall not knowingly disturb, alter, destroy or take any larger
and more conspicuous fossils of significant scientific interest, and shall
protect all such fossils in conformance with the measures included in the
approval of the mining and reclamation plan or exploration plan.

(3) The lessee shall immediately bring any such fossils that might be altered or
destroyed by his operation to the attention of the Regional Director or the
District Mining Supervisor, as appropriate. Operations may continue as long as
the fossil specimen or specimens would not be seriously damaged or destroyed by
the activity. The Regional Director or the District Mining Supervisor, as
appropriate, shall evaluate or have evaluated such discoveries brought to his
attention and, within five (5) working days, shall notify the lessee what action
shall be taken with respect to such discoveries.

(4) All such fossils of significant scientific interest shall mean under the
jurisdiction of the United States until ownership is determined under applicable
law. Copies of all paleontological resource data generated as a result of the
lease term requirements will be provided to the Regional Director or the
District Mining Supervisor, as appropriate.

(5) The cost of any required salvage of such fossils shall be borne by the
United States.

(6) These conditions apply to all such fossils of significant scientific
interest discovered within the lease area whether discovered in the overburden,
interburden, or coal seam or seams.

     (c) The Lessee will protect all survey monuments, witness corners,
reference monuments, and bearing trees against destruction, obliteration, or
damage during operations on the lease area. If any monuments, corners, or
accessories are destroyed, obliterated, or damaged

                                                                              10

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 location, using surveying procedures in accordance with
the "Manual of Surveying Instructions for the Survey of the Public Lands of the
United States," and will record the survey in the appropriate county records,
with a copy sent to the Authorized Officer.

     (d) The lessee shall comply with all valid and applicable laws and
regulations of Federal, State, and local governmental authority.

PART II: TERMS AND CONDITIONS

Sec. 1. (a) RENTAL RATE - Lessee shall 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 shall not be credited against either production or
advance royalties for any year.

Sec. 2. (a) PRODUCTION ROYALTIES - The royalty shall be 12 1/2 percent of the
value of the coal produced by strip or auger methods and 8 percent of the value
of the coal produced by underground mining methods. The value of the coal shall
be determined as set forth in 43 CFR 3480. 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 lessee, the authorized officer 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 shall 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 shall maintain in the proper office a lease bond in the
amount of $1,723,000.00. The authorized officer may require an increase in this
amount when additional coverage is determined appropriate.

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 the 10 years shall terminate the lease. If not submitted already, lessee
shall submit an operation and reclamation plan pursuant to Section 7 of the Act
no later than 3 years after the effective date of this lease readjustment.

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 shall 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 shall then be subject to the lease terms which would
have been applied if the lease had not been included in an LMU.

                                                                               3

Sec. 6. DOCUMENTS, EVIDENCE AND INSPECTION - At such times and in such form as
lessor may prescribe, lessee shall 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 shall keep open at all reasonable times for the inspection of any duly
authorized officer of lessor, the leased premises and all surface and
underground improvements, works, machinery, ore stockpits, equipment, and all
books, accounts, maps, and records relative to operations, surveys, or
investigations on or under the leased lands.

Lessee shall 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
shall be closed to inspection by the public in accordance with the Freedom of
Information Act (5 U.S.C. 552).

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

Lessee shall 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 shall be submitted to
the authorized officer.

Lessee shall 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 shall
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 minerals deposits not
covered hereunder, and approving easements or rights-of-way. Lessor shall
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 shall:
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

                                                                               4

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 the 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 shall maintain
segregated facilities.

          association or corporation qualified to hold such lease interest.

     [ ]  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.

     [ ]  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 shall 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
times as all portions of this lease are returned to lessor, lessee shall 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 shall remove from the premises all
other structures, machinery, equipment, tools, and materials that it elects to
or as required by the authorized officer. Any such structures, machinery,
equipment, tools and materials remaining on the leased lands beyond 180 days or
approved extension thereof, shall become the property of the lessor, but lessee
shall either remove any or all such property or shall 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 shall waive the requirement for
removal, provided the third parties do not object to such waiver. Lessee shall,
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 shall be subject to

                                                                               5

cancellation by the lessor only by judicial proceedings. This provision shall
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
shall 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 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 hereto.

Sec. 13. INDEMNIFICATION - Lessee shall 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. 14. SPECIAL STATUTES - This lease is subject to the Federal Water Pollution
Control Act (33 U.S.C. 1151-1175), the Clean Air Act (42 U.S.C. 1857, et seq.),
and to all other applicable laws pertaining to exploration activities, mining
operations and reclamation, including the Surface Mining Control and Reclamation
Act of 1977 (30 U.S.C. 1201 et seq.).

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 officer 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.

                                                                               6

(2) The lessee shall protect all cultural resource properties 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.

(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 surface managing agency
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
surface disturbing activities, the find will be reported to the Authorized
Officer immediately. Surface disturbing activities will be suspended within 250
feet of said 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 of significant scientific interest
discovered during the mining operations.

(c) 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.

(d) 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.

                                                                               7

(e) 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 unrecovered coal.

The parties recognize that under an approved R2P2, conditions may require a
modification by the operator/lessee of that plan. In the event a coalbed or
portion thereof is not to be mined or rendered unmineable by the operation, the
operator/lessee shall submit appropriate justification to obtain approval by the
authorized officer (AO) to leave such reserves unmined. Upon approval by the AO,
such coalbeds 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 rights to relinquish all or portion of the lease as authorized by
statute and regulation.

In the event the AO determines that the R2P2, as approved, will not attain MER
as the result of changed conditions, the AO will give proper notice to the
operator/lessee as required under applicable regulations. The AO 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 AO that the coal reserves have been rendered
unmineable or at such time that the operator/lessee has 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 noncompliance. A decision or notice of noncompliance issued by the lessor
that payment is due under this stipulation is appealable as allowed by law.

(f) 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 location, using 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.

                                                                               8

these stipulations shall be deemed a failure of the Lessee to comply with the
terms of this lease. The Lessee shall require his agents, contractors and
subcontractors involved in activities concerning this lease to include those
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.
The Lessor may amend these stipulations at any time without the consent of the
Lessee in order to make them consistent with any new federal or state statutes
and the regulations promulgated under authority or new statutes.

(a) Cultural Resources - (1) Before undertaking any activities that may disturb
the surface of the leased lands, the leasee 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 or
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 Regional Director of the Office of Surface
Mining (or the District Mining Supervisor if activities are associated with coal
exploration outside an approved mining permit area) and the authorized officer
of the BLM or the surface managing agency (if different). The lessee shall
undertake measures, in accordance with instructions from the Regional Director
for the District Mining Supervisor if activities are associated with coal
exploration outside an approved mining permit area), to protect cultural
resources on the leased land. The lessee shall not commence the surface
disturbing activities until permission to proceed is given by the Regional
Director (or the District Mining Supervisor if activities are associated with
coal exploration outside an approved mining permit area).

(2) The lessee shall protect all cultural resources properties 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 plan
or exploration plan.

(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 Regional Director
(or the District Mining Supervisor if activities are associated with coal
exploration outside an approved mining permit area), or the authorized officer
of the surface managing agency if the Regional Director, or District Mining
Supervisor, as appropriate, is not available. The lessee shall not disturb such
resources except as may be subsequently authorized by the Regional Director (or
the District Mining Supervisor if activities are associated with coal
exploration outside an approved mining permit area). Within two (2) working days
of notification, the Regional Director (or the District Mining Supervisor if
activities are associated with coal exploration outside an approved mining
permit area) 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 surface managing

                                                                               9

agency 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 - (1) Before undertaking any activities that may
disturb the surface of the leased lands, the lessee shall contact the Bureau of
Land Management to determine whether the authorized officer will require the
lessee to conduct a paleontological appraisal of the mine plan and adjacent
areas, or exploration plan areas, that may be adversely affected by
lease-related activities. If the authorized officer determines that one is
necessary, the paleontological appraisal shall be conducted by a qualified
paleontological approved by the authorized officer of the surface managing
agency (BLM if the surface is privately owned), using the published literature
and, where appropriate, field appraisals for determining the possible existence
of larger and more conspicuous fossils of scientific significance. A report of
the appraisal and recommendations for protecting any larger and more conspicuous
fossils of significant scientific interest on the leased lands so identified
shall be submitted to the authorized officer of the surface managing agency (BLM
if the surface is privately owned). When necessary to protect and collect the
larger and more conspicuous fossils of significant scientific interest on the
leased lands, the lessee shall undertake the measures provided in the approval
of the mining and reclamation plan or exploration plan.

(2) The lessee shall not knowingly disturb, alter, destroy or take any larger
and more conspicuous fossils of significant scientific interest, and shall
protect all such fossils in conformance with the measures included in the
approval of the mining and reclamation plan or exploration plan.

(3) The lessee shall immediately bring any such fossils that might be altered or
destroyed by his operation to the attention of the Regional Director or the
District Mining Supervisor, as appropriate. Operations may continue as long as
the fossil specimen or specimens would not be seriously damaged or destroyed by
the activity. The Regional Director or the District Mining Supervisor, as
appropriate, shall evaluate or have evaluated such discoveries brought to his
attention and, within five (5) working days, shall notify the lessee what action
shall be taken with respect to such discoveries.

(4) All such fossils of significant scientific interest shall mean under the
jurisdiction of the United States until ownership is determined under applicable
law. Copies of all paleontological resource data generated as a result of the
lease term requirements will be provided to the Regional Director or the
District Mining Supervisor, as appropriate.

(5) The cost of any required salvage of such fossils shall be borne by the
United States.

(6) These conditions apply to all such fossils of significant scientific
interest discovered within the lease area whether discovered in the overburden,
interburden, or coal seam or seams.

     (c) The Lessee will protect all survey monuments, witness corners,
reference monuments, and bearing trees against destruction, obliteration, or
damage

                                                                              10

during operations on the lease area. 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 location, using
surveying procedures in accordance with the "Manual of Surveying Instructions
for the Survey of the Public Lands of the United States," and will record the
survey in the appropriate county records, with a copy sent to the Authorized
Officer.

(d) The lessee shall comply with all valid and applicable laws and regulations
of Federal, State, and local governmental authority.
