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 it 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, 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 


4







 



managing
agency, if different. The lessee shall undertake measures, in accordance with instructions from the Regional 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 Regional Director or authorized officer. 


(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 Regional Director or authorized officer, or the authorized
officer of the surface managing agency, if the Regional Director is not available. The lessee shall not disturb such resources except as may be subsequently authorized by the Regional Director or
authorized officer.
Within two (2) working days of notification, the Regional 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 construction, the find will be reported to the authorized officer immediately. Construction 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)
The BLM realizes that coal mining operations conducted on leases issued within producing oil and gas fields may interfere with the economic recovery of oil and gas; just as oil and gas leases
issued in a coal lease may inhibit coal production. BLM retains authority to alter and/or modify coal operations or oil and gas operations on lands covered by Federal leases so as to obtain maximum
resource recovery.

Qualifications Accepted; Name Change Recognized;

Logical Mining Unit Modified; Bond Accepted;

Period of Liability Terminated  


On
July 27, 1998, we received evidence and documentation that Kennecott Energy and Coal Company has purchased the stock of Kerr-McGee Coal Corporation. Upon closing,
Kerr-McGee Coal Corporation changed its name to Jacobs Ranch Coal Company. Additionally, we have received a qualifications statement for Jacobs Ranch Coal Company along with bond
number 400JZ3979, with St. Paul Fire and Marine Insurance Company as surety, and Jacobs Ranch Coal Company as principal, in the amount of $4,190,000 to provide coverage for the
above-referenced leases included in the Jacobs Ranch Logical Mining Unit (LHU). 


The
qualifications statement and bond have been examined, found satisfactory, and are accepted effective July 27, 1998. 


The
period of liability under LMU bond number 2971100-2645, with Safeco Insurance Company of America as surety, and Kerr-McGee Coal Corporation as principal, is hereby
terminated effective July 27, 1998, the acceptance date of the replacement, bond. 


The
records of this office have been changed to reflect that the lessee of record for the leases in the Jacobs Ranch Mine is Jacobs Ranch Coal Company. We have also changed our records to reflect that
Jacobs Ranch Coal Company is now the applicant for both Federal coal lease application WYW136458 filed April 14, 1995 and Federal coal exploration license WYW144836 filed February 25,
1998. 


Additionally,
Kennecott Energy and Coal Company has requested that the Jacobs Ranch LMU be modified to change the unit operator from Kerr-McGee Coal Corporation to Jacobs Ranch Coal
Company. The LMU is hereby modified to reflect that Jacobs Ranch Coal Company is the operator and will be responsible for operations under the LMU in accordance with the LMU approval document.
