         Competitive Offer(s), it shall first afford Seller the
         opportunity to furnish such quantity by following the
         procedures set forth in paragraph (i) above.  

  (iii)  Each time Buyers desire to purchase Coal for use in Unit
         4 during the period January 1, 2014 through December 31, 
         2020, they shall follow the procedure set forth above.

     Section 4.  Deficient Quantity Charge and Payment.

     (a)  Deficient  Quantity  Charge.  For Contract Year 1994
and each Contract Year thereafter, the Deficient Quantity Charge
shall be calculated as follows:
         A = B ((AR1 + AR2 + AR3 + AR4)/4)

    Where:

         A=the Deficient Quantity Charge.
         B=the previous Contract Year's Deficient Quantity
         Charge.

    AR1=the Quarterly Adjustment Ratio calculated pursuant to
    Section 1(oo) hereof and in effect on January 1 of the
    Contract Year during which Buyers incurred the Deficient
    Quantity.

    AR2=
    the Quarterly Adjustment Ratio calculated pursuant to Section
    1(oo) hereof and in effect on April 1 of the Contract Year
    during which Buyers incurred the Deficient Quantity.

    AR3=
    the Quarterly Adjustment Ratio calculated pursuant to Section
    1(oo) hereof and in effect on July 1 of the Contract Year
    during which Buyers incurred the Deficient Quantity.

    AR4=
    the Quarterly Adjustment Ratio calculated pursuant to Section
    1(oo) hereof and in effect on October 1 of the Contract Year
    during which Buyers incurred the Deficient Quantity.

     (b) Deficient Quantity Payment.  If, during any Contract
Year, Buyers incur Deficient Quantity, then they shall pay Seller
an amount determined by multiplying the Deficient Quantity Charge
for such Contract Year by the Deficient Quantity.  Such amount
shall be paid by Buyers in six consecutive equal monthly
installments beginning with the first such installment due and
payable on or before April 15 of the Contract Year succeeding the
Contract Year in which the Deficient Quantity is incurred. 
Seller, on or before March 1 of such succeeding Contract Year,
shall furnish Buyers with an invoice showing the total and
monthly amounts due for such Deficient Quantity along with any
appropriate documentation supporting the calculation of such
amounts.  Exhibit I attached hereto and hereby made a part hereof
is representative of the actual method and procedure which Buyers
and Seller have agreed shall be followed in calculating the
Deficient Quantity payment for any applicable Contract Year.

     Section 5.  Source and Dedication; Buyers' Request for Belle
Ayr Mine  Coal; Alternate Source Coal; Loading; Deliveries; Title
and Risk of Loss.

     (a)  Source and Dedication.  Basic Source Coal to be
delivered by Seller under this Agreement shall be from the Mine;
provided, Seller shall have the right at any time, and from time
to time, to deliver Coal from Seller's Belle Ayr Mine located
near Gillette, Wyoming and shown on Exhibit A hereto to be used
by itself or blended with Coal at the Mine; and all such Coal
shall be considered to be Basic Source Coal for all purposes
hereunder; provided further, if Seller delivers any Basic Source
Coal from the Belle Ayr Mine or blends Belle Ayr Coal with Coal
at the Mine, it shall notify Agent/Operator in writing prior to
the loading of any such Coal or anytime (i) a change is made to
return Coal sourcing to the Mine or (ii) it discontinues blending
at the Mine.  Seller hereby dedicates to Buyers the total
quantities of Coal from the Mine that are required, or may be
required, to be delivered to Buyers in order for Seller to
fulfill the commitments undertaken by it under this Agreement.
     (b)  Buyers' Request for Belle Ayr Mine Coal.  Buyers shall
have the right at any time, and from time to time, to request
that Seller deliver Coal during each Contract Year from the Belle
Ayr Mine.  If Seller, in its sole discretion, agrees to deliver
such requested quantity of Coal or portion thereof then the
applicable Additional Charge shall be added to the then
applicable Price or Incremental Price.
     (c)  Alternate Source Coal.  (i) Seller, at all times during
the Term, shall have the right, but not the obligation, to
deliver to Buyers all or part of the Annual Base Quantity from
alternate sources ("Alternate Source Coal") without regard to
whether or not the source mine or mines are owned or controlled
by Seller ("Alternate Source Mines"), so long as such Alternate
Source Coal: (A) is delivered to the Energy Center at a cost per
MMBtu (defined as including cost of Alternate Source Coal,
transportation, loss in transit, any required chemical additive
and rail equipment and/or any other items required to deliver
Coal in a usable form and including the Utilization Cost) not
higher than the cost per MmBtu of Mine Coal delivered to the
Energy Center; (B) is of substantially the same or better quality
and has substantially the same or better characteristics as
required for Basic Source Coal pursuant to Section 6(a) hereof;
(C) enables Buyers, by performance or by compromise agreeable to
Buyers, Seller and Buyers' rail carrier, to comply with Buyers'
obligations under transportation agreements in existence and in
effect at the time of delivery; and (D)  has been approved by
Buyers in their reasonable discretion pursuant to the procedures
set forth below.
    (ii)  In  addition,  Seller's  right  to  supply  Alternate 
Source Coal is subject to the following conditions:
    (A)  At any time, and from time to time, Seller, if it
         desires to supply Alternate Source Coal, shall request 
         Agent/Operator's approval for the delivery of Alternate
         Source Coal.  At the time of such request Seller shall
         provide Agent/Operator with the proximate and ultimate
         analyses of such Coal and shall make available
         quantities of such Alternate Source Coal as
         Agent/operator may reasonably request for purposes of
         analyzing and testing, including test burns in the
         Energy Center.  All such test Coal shall be priced as
         though it was Alternate Source Coal purchased hereunder
         by Agent/Operator.   Agent/Operator shall notify Seller
         of its approval or disapproval of such Alternate Source
         Coal within 30 days of the later of its receipt of (A)
         Seller's request or (B) the last shipment of such
         Alternate Source Coal for the test burn.  If
         Agent/Operator has notified Seller that it has approved
         such Alternate Source Coal, it shall also advise Seller
         in such notice of the Utilization Cost. Such Utilization
         Cost shall be fixed and firm for a period of twelve
         months from the date Agent/Operator so notifies Seller. 
         If Seller desires to deliver such Alternate Source Coal
         beyond the twelve month period, it shall notify Buyers
         at least 90 days prior to the expiration of such twelve
         month period and Buyers, within 60 days of receipt of
         such notice, shall advise Seller of the Utilization Cost
         to be effective during the ensuing twelve month period.

    (B)  When securing an Alternate Source Coal for shipment to
         Agent/Operator, Seller shall also secure for
         Agent/Operator access to and the right to inspect the
         mining, weighing, sampling and other applicable
         operations of the Alternate Source Mine.

    (C)  The price payable by Buyers for Alternate Source Coal,
         taking into account the Utilization Cost, shall be
         calculated pursuant to the procedure set forth in
         Exhibit 0 attached hereto and hereby made a part hereof;
         provided, if the parties are unable to agree on the
         Utilization Cost from such Alternate Source Coal and
         Seller desires to deliver Alternate Source Coal as the
         result of operational problems, including coal quality,
         at the Mine or Belle Ayr Mine, then pending resolution
         of such Utilization Cost, Buyers will take the Alternate
         Source Coal for such period as long as such Coal meets
         the other conditions set forth in this section 5(c);
         provided further, the price for Alternate Source Coal
         shall not exceed the Price less the Utilization Cost.

     (d)     Railcar Loading; Rail Tariff.  The Coal to be sold
and delivered hereunder shall be loaded F.O.B. railcars at the
Mine, Belle Ayr Mine or Alternate Source Mine with freight
charges paid by Buyers.  Coal shall be loaded into railcars
provided by Buyers in accordance with the applicable tariff
and/or contract requirements of Buyers, rail carrier(s) for
transportation by rail to the Energy Center.  Seller agrees to
pay all costs, penalties, or increases in freight charges
incurred solely due to Seller's failure to comply with those
applicable tariff and/or contract requirements relative to
loading and weighing time and loaded railcar weight which
requirements (i) are set forth in Exhibit M attached hereto and
hereby made a part hereof or (ii) might be
modified or changed in the future and consented to in writing by
Seller, which consent shall not unreasonably be withheld;
provided, Seller shall not have to incur any increased cost in
order to comply with such new requirements.
     (e)     Title and Risk of Loss.  Delivery and title to the
Coal shall pass to Buyers when a loaded unit train departs the
Mine, Belle Ayr Mine or Alternate Source Mine, if applicable, for
its ultimate destination.  Risk of loss shall follow title.
     (f)     Regular Deliveries.  Subject to other provisions of
this Agreement and taking into account the regularly scheduled
holidays and vacation periods of the employees at the Mine,
deliveries of Coal hereunder shall be made in approximately equal
weekly quantities.  Such delivery schedules may be adjusted at
any time by mutual agreement between the parties.


     Section 6.  Quality of Coal.
     (a)     Coal Specifications.  Except if and to the extent
that Seller and Buyers may from time to time agree in writing,
Coal to be supplied hereunder shall be:
     (i)  substantially free from impurities such  as,  but  not
          limited to, bone, slate, earth, rock, pyrite,  wood,
          tramp metal and mine debris;

    (ii)  sized to a top size of two inches (2"); and

   (iii)  of a typical weighted average quality over any monthly
          period substantially equal to the following    
          specifications, on an "as received basis", as
          established by analyses of samples taken and analyzed as
          provided in Section 11 hereof, to-wit:

Coal Characteristics                       Specifications

     (b)  Off-Specification Coal.  Seller shall take all
reasonable necessary precautions in order to avoid delivering
Coal to Buyers that does not meet the above specifications;
however, in the event Off-Specification Coal is delivered, Buyers
shall pay for all such Off-Specification Coal at a price
equivalent to 90 percent of the Price or Incremental Price, as
the case may be.  In the event the monthly weighted average
analysis shows that Off-Specification Coal has been delivered,
Buyers have the option to suspend all further shipments until
Buyers are reasonably assured by Seller that Seller will be able
to deliver Coal which will meet the specifications as set out in
Section 6(a) hereof.  If Buyers suspend shipments pursuant to
this Section 6(b), then the Annual Base Quantity shall be reduced
by an amount equal to the product obtained by multiplying the
number of days of such suspension by the result obtained by
dividing the Annual Base Quantity by 365.

     Section 7.  Price and Incremental Price: Certain Taxes:
Economic Controls.
     (a)     Price and Incremental Price.  Buyers shall pay to
Seller the Price for Annual Base Quantity Coal and the
Incremental Price for Incremental Quantity Coal delivered F.O.B.
railcars at the Mine, the Belle Ayr Mine or Alternate source Mine
and accepted under this Agreement.  The Price shall consist of
the IC and RTRC and shall be calculated from time to time as
provided for in Section 8(a) hereof.  The Incremental Price shall
consist of the ICIP and RTRCIP and shall be calculated or
redetermined from time to time as provided for in Section 8(b)
hereof.
     (b)  Certain Taxes.  If any sales tax, excise tax, use tax
or similar taxes applicable to the sale or use of Coal are levied
at or after the point of delivery, Buyers shall either pay such
taxes directly or reimburse Seller if Seller has paid such taxes.
     (c)  Economic Controls.  In the event the effect of any
adjustment or redetermination of the Price or Incremental Price
provided for herein is hereafter prevented, suspended or limited
by any economic controls required or established by applicable
laws, rules or regulations promulgated by federal, state, county
or local governmental bodies or agencies, then, upon and as of
the effective date of the repeal, modification or lapse thereof,
in whole or in part, the Price or Incremental Price shall be
revised to give effect to all adjustments thereto and
redeterminations thereof required or permitted under this
Agreement but not theretofore made due to such economic controls. 
Such revised Price or Incremental Price shall apply (until
further adjusted or redetermined from time to time) to all
subsequent deliveries of Coal made hereunder.
     Section 8.  Calculation of Price and Incremental Price.
     (a)  Price Components.  Beginning January 1, 1993, the Price
shall consist of two components:  RTRC and IC and shall be an
amount equal to the sum of such components.  The Price shall be
calculated from time to time to reflect the respective amounts
contained in the RTRC and IC components.  Each of these
components shall be calculated pursuant to this Section 8.  An
example of the operation of this Section 8 using hypothetical
numbers is set forth in Exhibits B through E and Exhibit G which
are attached hereto and hereby made a part hereof.  Exhibits B
through E and Exhibit G are representative of the actual methods
and procedures which Buyers and Seller have agreed shall be
followed, except as otherwise provided for in this Agreement, in
making the calculations.
     (i)  Calculation of RTRC.  The RTRC shall be an amount
          equal to the sum of the values of the items of the
          RTRC set forth in Sections 8(a)(i)(C),(D),(E),(F), and
          (G) hereof and any items added pursuant to Section 
          8(c)(i) hereof.  Such values shall be calculated
          Quarterly beginning January 1, 1993, and at any other
          time that a change occurs in the respective value of
          any such item included in the RTRC. Calculations
          shall be made using actual amounts unless such actual
          amounts are not available in which case reasonable
          estimated amounts shall be used.  Documentation to
          substantiate the use of such actual or reasonable
          estimated amounts shall be provided by Seller to
          Buyers at the time Seller notifies Buyers of any
          change in the RTRC.  If an estimated amount for any
          item is used in the calculation of the RTRC, then
          such amount shall be reconciled with the final actual
          amount of such item as soon as such actual amount
          becomes known and, if there is a difference between
          the two such amounts, then an appropriate invoice
          shall be issued pursuant to Section 9(a) hereof.   

          The value for each item of the RTRC and the CP shall
          be solved to six decimal places.  The respective
          values of the items of the RTRC shall be added
          together and the result thereof shall be rounded to
          four decimal places to determine the RTRC.  Such
          calculations shall be made pursuant to the following
          procedures and formulas:

          (A) The symbols, descriptions, units of measure and
              data sources used to determine values for the items
              of the RTRC calculated by equations, set forth in
              Section 8(a)(i)(B) hereof, are set forth in the RTRC
              EQUATION RELATED SYMBOLS TABLE below:

          (B)  The equations used to determine values for items
               of the RTRC calculated by equations are:

               (1)  BLT = (CP-BLT) (BLR/100)
                    but not more than the statutory maximum
                    per ton expressed as $/MMBtu based on 
                    8300 Btu/lb.

               (2)  R + (CP) (RR) (FRT)/((TT) (100))

               (3) PRT = (((CP-R-ORG-BLT-PRT) (MDC/TDC))+

                   ORG+BLT+PRT) (PRTR)/100

               (4) ORG = (CP-BLT-PRT-
                   R+((.20) (FRT)/(TT)))) (ORR/100

               (5) S = (CP-R-ORG) (FDR-CDR) (TR)/10,000

               (6) CP = IC+R+ORG+PRT+BLT+S

               These equations shall be solved and the equation
               determined items of the RTRC calculated
               simultaneously by direct substitution iteration
               until no change is noted in the sixth decimal place
               in each of the variables on both sides of the equal
               sign in each equation and the resultant items of
               the RTRC shall be rounded to six decimal places.
               The non-variable values shall be input to four
               decimal places.  The above equations exclude the
               Reclamation Fee (however, it is agreed that if the
               current statutory amount of such Fee is changed by
               a New Law, then the difference between the amount
               imposed by the New Law and the current amount shall
               be included in the RTRC calculations) and Amax Land
               Royalties from the appropriate equations in effect
               on January 1, 1993, because of their inclusion in
               the IC.  If, as a result of an action of a third
               party, any of the above equations no longer
               accurately determines the value of the applicable '
               item of the RTRC, then an appropriate change in
               such equations) shall be made; provided, if, in
               calculating values for items (3), (4) and (5) of
               the RTRC enumerated above, a third party, as of
               December 31, 1992, deducted amounts for the
               Reclamation Fee and/or Amax Land Royalties, then
               amounts for the Reclamation Fee and/or Amax Land
               Royalties shall never be used in calculating such
               values hereunder and the changed equations) shall
               replace the appropriate above equations).  In such
               event Seller shall submit revised equations to
               Buyers, along with supporting documentation, for
               Buyers' written approval, which shall not
               unreasonably be withheld.
 
          (C)  The Wyoming severance taxes and Campbell County
          (Wyoming) ad valorem taxes on production item of the
          RTRC shall be calculated by the equation specified in
          Section 8 (a) (i) (B) (3) hereof.  An example
          calculation is shown on Exhibit C hereto.

          (D)  The statutory depletion item of the RTRC shall be 
          calculated by the equation specified in Section
          8(a)(i)(B)(5) hereof.  An example calculation is shown
          on Exhibit C hereto.
          (E)  The Federal Royalty item of the RTRC shall be
          calculated by the equation specified in Section
          8(a)(i)(B)(2) hereof.  An example calculation is shown
          on Exhibit C hereto.

          (F)  The John Organ Royalty item of the RTRC shall be
          calculated by the equation specified in Section
          B(a)(i)(B)(4) hereof. 

          An example calculation is shown on-Exhibit C hereof.

          G)  The Federal Black Lung Excise Tax item of the RTRC
          shall be calculated by the equation specified in Section
          8(a) (i) (B) (1) hereof.  An example calculation is
          shown on Exhibit C hereto.

    (ii)  Adjustment of IC.     As of January 1, 1993, the IC
          shall be $0.3455/MMBtu and shall thereafter be adjusted
          Quarterly during each Contract Year.  The IC for an
          Adjustment Quarter shall be determined by multiplying
          the amount of the IC for the previous Quarter by the
          Quarterly Adjustment Ratio for such Adjustment Quarter.
          The product of such calculation shall be rounded to four
          decimal places.  If any information needed for the
          calculation of the Quarterly Adjustment Ratio is not
          available until after the beginning of an Adjustment
          Quarter, the calculation of the Quarterly Adjustment
          Ratio shall be applied retroactively to the beginning of
          such Adjustment Quarter.  Seller shall use all
          reasonable efforts to provide Buyers with documentation
          to substantiate the use of all calculations, whether
          based upon estimated amounts or actual amounts, together
          with supporting calculations and appropriate
          documentation, no later than 30 days prior to the
          beginning of the Adjustment Quarter.  If an estimated
          amount for any item is used in the calculation of the
          IC, then such amount shall be reconciled with the final
          actual amount of such item as soon as such actual amount
          becomes known and, if there is a difference between the
          two such amounts, then an appropriate invoice shall be
          issued pursuant to Section 9 (a) hereof.  Example
          calculations are shown on Exhibits D, E and G hereto.


     (b)  Incremental Price Calculation and Redetermination. 
Beginning January 1, 1993, the Incremental Price shall consist of
two components: RTRCIP and ICIP and shall be an amount equal to
the sum of such components.  The Incremental Price shall be
calculated from time to time to reflect the respective amounts
contained in the RTRCIP and ICIP components.  Each of these
components shall be calculated pursuant to this Section 8.  An -
example of the operation of this Section 8 using hypothetical
numbers is set forth in Exhibit B and Exhibits D through G
hereto.  Exhibit B and Exhibits D through G are representative of
the actual methods and procedures which Buyers and Seller have
agreed shall be followed, except as otherwise provided for in
this Agreement, in making the calculations.
     (i)  Calculation of RTRCIP.       The RTRCIP shall be an
          amount equal to the sum of the values of the items of
          the RTRCIP set forth in Sections 8(b) (i) (C), (D),
          (E),(F) and (G) hereof and any items added pursuant to
          Section 8 (c) (i) hereof.  Such values shall be
          calculated Quarterly beginning January 1, 1993, and at
          any other time that a change occurs in the respective
          amount of any item included in the RTRCIP.  Calculations
          shall be made using actual amounts unless such actual
          amounts are not available in which case reasonable
          estimated amounts shall be used.  Documentation to
          substantiate the use of such actual or reasonable
          estimated amounts shall be provided by Seller to Buyers
          at the time Seller notifies Buyers of any change in the
          RTRCIP.  If an estimated amount for any item is used in
          the calculation of the RTRCIP, then such amount shall be
          reconciled with the final actual amount of such item as
          soon as such actual amount becomes known and, if there
          is a difference between the two such amounts, then an
          appropriate invoice shall be issued pursuant to Section
          9(a)hereof.  The value of each item of the RTRCIP and
          the  CIP shall be solved to six decimal places.  The
          respective values of the items of the RTRCIP shall be
          added together and the result thereof, shall be rounded
          to four decimal places to determine the RTRCIP.  Such
          calculations shall be made pursuant to the following
          procedures and formulas:

     (A)  The symbols, descriptions, units of measure and data
          sources used to determine values for the items of the
          RTRCIP calculated by equations, set forth in Section
          8 (b) (i) (B) hereof, are set forth in the RTRCIP

     (B)  The equations used to determine values for items of
          the RTRCIP calculated by equations are:

     (1)  BLT = (CIP-BLT)(BLR/100)
          but not more than the statutory maximum per ton         
          expressed as $/MMBtu based on 8300 Btu/lb.

     (2)  R = (CIP)(RR)(FRT)/((TT)(100))

     (3)  PRT = (((CIP-R-ORG-BLT-PRT) (MDC/TDC)) +ORG+ BLT+PRT)
          (PRTR) /100

     (4)  ORG = (CIP-BLT-PRT-R+

     (5)  S = (CIP-R-ORG)(FDR-CDR)(TR)/10,000

     (6)  CIP = ICIP+R+ORG+PRT+BLT+S


These equations shall be solved and the equation determined items
of the RTRCIP calculated simultaneously by direct substitution
iteration until no change is noted in the sixth decimal place in
each of the variables on both sides of the equal sign in each
equation and the resultant items of the RTRCIP shall be rounded
to six decimal places.  The non-variable values shall be input to 
four decimal places.  The above equations exclude the Reclamation
Fee (however, it is agreed that if the current statutory amount
of such Fee is changed by a New Law, then the difference between
the amount imposed by the New Law and the current amount shall be
included in the RTRCIP calculations) and Amax Land Royalties from
the appropriate equations in effect on January 1, 1993, because
of their inclusion in the ICIP.  If, as a result of an action of
a third party, any of the above equations no longer accurately
determines the value of the applicable item of the RTRCIP, then
an appropriate change in such equations) shall be made provided,
if, in calculating values for items (3), (4) and (5) of the
RTRCIP enumerated above, a third party, as of December 31, 1992,
deducted amounts for the Reclamation Fee and/or Amax Land
Royalties, then amounts for the Reclamation Fee and/or Amax Land
Royalties shall never be used in calculating such values
hereunder and the changed equations) shall replace the
appropriate above equations).  In such event Seller shall submit
revised equations to Buyers, along with supporting documentation,
for Buyers' written approval, which shall not unreasonably be
withheld.

     (C)  The Wyoming severance taxes and Campbell County
          (Wyoming) ad valorem taxes on production item of the
          RTRCIP shall be calculated by the equation specified in
          Section 8(b)(i)(B)(3) hereof.  An example calculation is
          shown on Exhibit F hereto.


     (D)  The statutory depletion item of the RTRCIP shall be
          calculated by the equation specified in Section
          8(b)(i)(B)(5) hereof.  An example calculation is shown
          on Exhibit F hereto.

     (E)  The Federal Royalty item of the RTRCIP shall be
          calculated by the equation specified in Section
          8(b)(i)(B)(2) hereof.  An example calculation is shown
          on Exhibit F hereto.

     (F)  The John Organ Royalty item of the RTRCIP shall be
          calculated by the equation specified in Section
          8(b)(i)(B)(4) hereof.  An example calculation is shown
          on Exhibit F hereto.

     (G)  The Federal Black Lung Excise Tax item of the RTRCIP
          shall be calculated by the equation specified in Section
          8 (b) (i) (B) (1) hereof.  An example calculation is
          shown on Exhibit F hereto.

    (ii)  Adjustment of ICIP.  As of January 1, 1993, the ICIP
          shall be $0.1540/MMBtu and shall thereafter be adjusted
          Quarterly during each Contract Year.  The ICIP for an
          Adjustment Quarter shall be determined by multiplying
          the amount of the ICIP for the previous Quarter by the
          Quarterly Adjustment Ratio for such Adjustment Quarter.
          The product of such calculation shall be rounded to four
          decimal places.  If any information needed for the
          calculation of the Quarterly Adjustment Ratio is not
          available until after the beginning of an Adjustment
          Quarter, the calculation of the Quarterly Adjustment
          Ratio shall be applied retroactively to the beginning of
          such Adjustment Quarter.  Seller shall use all
          reasonable efforts to provide Buyers with documentation
          to substantiate the use of all calculations, whether
          based upon estimated amounts or actual amounts, together
          with supporting calculations and appropriate
          documentation, no later than 30 days prior to the
          beginning of the Adjustment Quarter.  If an estimated
          amount for any item is used in the calculation of the
          ICIP, then such amount shall be reconciled with the
          final actual amount of such item as soon as such actual
          amount becomes known and, if there is a difference
          between the two such amounts, then an appropriate
          invoice shall be issued pursuant to Section 9 (a)
          hereof.  Example calculations are shown on Exhibits D, E
          and G hereto.

   (iii)  Market Redetermination.  Notwithstanding anything
          contained to the contrary in this Agreement, and in
          addition to all other rights of the parties contained
          herein, it is agreed that a redetermination of the
          Incremental Price shall be made hereunder.  The purpose
          of such redetermination is to change the Incremental
          Price so that it is reflective of the then current
          market price for similar Powder River Basin coal sold to
          utility purchasers buying coal for their own consumption
          under five year coal supply agreements commencing at the
          time of the redetermination for the purchase of
          approximately 1,000,000 tons of coal per year and
          containing terms and conditions as set forth in
          Exhibit L attached hereto and hereby made a part hereof
          (hereinafter such current market price referred to as
          the "Market Price").

          Redeterminations of the Incremental Price pursuant to
          this Section 8(b)(iii) shall be effective on January 1,
          1998, January 1, 2003, January 1, 2008, January 1, 2013
          and January 1, 2018.

          Redetermination shall be initiated by Buyers serving
          written notice to Seller of the selection of their
          Consultant no later than August 15 prior to the
          Contract Year in which such redetermination of the
          Incremental Price shall become effective.  Upon receipt
          of such notice, Seller, within 10 days, shall notify
          Buyers of which Consultant it has chosen to determine
          the Market Price.

          After each party has received its Consultant's
          determination of the Market Price, Agent/operator and
          Seller shall compare their Consultants' Market Prices,
          on or before October 5. If either one of the Market
          Prices is within five percent of the simple arithmetic
          average of the two Consultant's Market Prices, then the
          simple  arithmetic average of the two Market Prices
          shall be the Incremental Price which will be effective
          on such respective January 1. If neither of the
          Consultant's Market Price is within five percent of the
          simple arithmetic average, as shown on Exhibit J-1
          hereto, then a third and fourth Consultant shall be
          selected in a random drawing from the list contained on
          Exhibit K hereto.  The third Consultant selected shall
          be contacted within 10 Business Days to ascertain if
          such Consultant can determine a Market Price by December
          1.  If the third Consultant cannot make such a timely
          determination, then the fourth Consultant shall be
          contacted as soon as possible to see if it can make such
          a timely determination.  This process shall be repeated,
          if necessary, until a Consultant is selected and if the
          process is delayed beyond the applicable January 1, the
          resulting Incremental Price shall be applied
          retroactively to such applicable January 1. Any
          communications with the third or fourth or subsequent
          Consultant must be made simultaneously by both
          Agent/Operator and Seller.  When the Consultant has
          determined the Market Price, the Incremental Price,
          which will become effective on each respective
          January 1, shall be the simple arithmetic average of all
          three Consultant's Market Prices, as shown on
          Exhibit J-2 hereto.  The ICIP effective on each
          respective January 1 shall be solved by using the
          Incremental Price and the formulas and non-variable
          inputs used to calculate each respective January 1
          RTRCIP.
     (c)     New  Laws.  After  December  31,  1992,  Seller's 
Law  Costs shall be calculated by Seller  and  the  amount 
(whether  an increase or decrease) of such change shall be
included in  either the  RTRC or the IC as an item of cost as
provided for below:
          (i)  Classification of Seller's Laws Cost.

          (A)  If an item of cost occasioned by a New Law is a
               specific amount per ton or other measure and is
               not then an item of the RTRC, then it shall become
               an item of and be included in the RTRC on the basis
               of the specific amount per ton, converted to the
               equivalent dollars per MMBtu based upon 8,300 Btu's 
               per pound, retroactively to the date the New Law
               first affected Seller's Laws Cost.

          (B)  If an item of cost occasioned by a New Law is   
               calculated as a percent of Seller's revenue from
               the sale of coal from the Mine less applicable
               deductions, if any, and is not then an item of the
               RTRC, then it shall become an item of and be
               included in the RTRC on the basis of an 
               amount calculated pursuant to the procedures set
               forth in Section 8 (a) (i) (B) hereof
               retroactively to the date the New Law first
               affected Seller's Laws Cost.

          (C)  If an item of cost occasioned by a New Law causes 
               Seller's operating costs at the Mine to increase    
               decrease, then such cost shall become an item of
               and be included in the IC on the basis of an amount
               calculated pursuant to the procedures set forth in
               Section 8 (c) (ii) or (iii) hereof.

          (D)   Any Seller's Laws Cost which can not be classified
                in one of the preceding sections, shall be
                classified as either an IC or RTRC cost by mutual
                agreement of the parties.


          (ii)  IC Related Cost Reduction.

          (A)  If Seller's Laws Cost is classified as an IC cost
               and is a reduction for an item of cost, then       
               Seller and Buyers shall agree on an estimated
               amount of the cost reduction and the IC shall be
               reduced by such amount retroactively to the date
               such New Law first affected Seller's Laws Cost and
               this estimated amount shall continue to be used in
               calculating the IC until Buyers and Seller agree
               to an amount pursuant to Section 8(c)(ii)(B)
               hereof.

          (B)  After the IC has been reduced pursuant to Section
               8(c)(ii)(A) hereof for the Survey Period, the
               actual amount of reduction for such item of cost
               shall be determined.  Seller shall calculate and
               present to Buyers, Seller's determination of the
               actual amount of such cost reduction for each
               Quarter of the Survey Period.  Buyers or Buyers'
               representative shall have the right at Buyers'
               expense to review Seller's applicable records to
               independently calculate and present to Seller,
               Buyers' determination of the actual amount of such
               cost reduction for each Quarter of the Survey
               Period. Such review shall include an eight Quarter
               period commencing four Quarters previous to
               the first Quarter of the Survey Period.  Buyers'
               review shall be completed within 120 days after
               Buyers or Buyers' representative has received all
               necessary data and information from Seller. 
               Seller and Buyers shall then review the
               available-data and agree on the
               actual cost reduction for each Quarter of the 
               Survey Period.

          (C)  After Buyers and Seller have reached an agreement
               pursuant to Section 8(c)(ii)(B) hereof, the Price
               for each Quarter of the Survey Period shall be
               recalculated based upon the new values of the IC
               (which shall reflect the actual amount of such
               cost reduction).  The total amount paid by Buyers
               for Coal delivered during the Survey Period shall
           be compared with the total amount that would have been 
             paid by Buyers if the recalculated Price had been in
           effect and Buyers' account shall either be credited
               or debited, as the case may be, for the amount of
               any difference between such total amounts.

          (D)   After Buyers and Seller have reached an agreement
                pursuant to Section 8(c)(ii)(B) hereof, the      
                weighted average actual amount of such cost
              reduction for such item of cost shall be calculated
              for the Survey Period.  For purposes of calculating
              the IC pursuant to Section 8(a)(ii) hereof for all
                Quarters subsequent to the Survey Period such
                weighted average actual amount of such cost
                reduction shall replace the estimated amount
                previously included in the IC for the fourth
                 Quarter of the Survey Period.

          (iii)  IC Related Cost Increase.

          (A)     If Seller's Laws Cost is classified as an IC 
          cost and is an increase f or an item of cost, then       
                    Seller and Buyers shall agree on an estimated
                  amount of the cost increase and include such
                  amount in the IC retroactively to the date the
                  New Law first affected Seller's Laws Cost and
                  this estimated amount shall continue to be used
                  in calculating the IC until Buyers and Seller
                  agree to an amount pursuant to Section
                  8(c)(iii)(B) hereof.

          (B)   After an item of cost has been included in the IC
                  pursuant to Section 8(c)(iii)(A) hereof for the
                Survey Period, the actual amount of increase for  
               such item of cost shall be determined.   Seller
                  shall calculate and present to Buyers, Seller's
                  determination of the actual amount of such cost
                  increase for each Quarter of the Survey Period.

                Buyers or Buyers's representative shall have the
                  right at Buyers' expense to review Seller's
                  applicable records to independently 
                  calculate and present to Seller, Buyers'
                  determination of the actual amount of such cost
                  increase for each Quarter of the survey Period.

                Such review shall include an eight Quarter period
                commencing four Quarters previous to the Quarter
                during which the IC was first increased and shall
                 be completed within 120 days after Buyers or
                Buyers' representative has received all necessary
                  data and information from Seller.  Seller and
                  Buyers shall then review the available data and
                  agree on the actual cost increase for each
                  Quarter of the Survey Period.

          (C)   After Buyers and Seller have reached an agreement
                  pursuant to Section 8(c)(iii)(B) hereof, the
                Price for each Quarter of the Survey Period shall 
                be recalculated based upon the new values of the
                IC (which shall reflect the actual amount of such
                cost increase).  The total amount paid by Buyers
                for Coal delivered during the Survey Period shall
                be compared with the total amount that would have
                been paid by Buyers if the recalculated Price had
                  been in effect and Buyers, account shall either
                  be credited or debited, as the case may be, for
                  the amount of any difference between such total
                  amounts. 

          (D)   After Buyers and Seller have reached an agreement
                  pursuant to Section 8 (c) (iii) (B) hereof, the
                  weighted average actual amount of such cost
                  increase for such item of cost shall be
                  calculated for the Survey Period.  For purposes
                  of calculating the IC pursuant to Section
                  8(A)(ii) hereof for the first Quarter after the
                  Survey Period, such weighted average actual
                  amount of such cost increase shall replace the
                  estimated amount previously included in the IC
                  for the fourth Quarter of the Survey Period.

          (iv)  ICIP and RTRCIP Adjustments.  If a classification
         of Seller's Law Costs pursuant to Section 8(c)(i) hereof
           results in an adjustment in the RTRC or IC then a
        similar adjustment shall be made to the RTRCIP or ICIP,
           as the case may be.  If adjustments to the RTRC or IC
       made pursuant to Section 8 (c) hereof result in a change
       in the Price, then a similar adjustment shall be made to
           the Incremental Price based upon the corresponding
           changes to the  RTRCIP and the ICIP.
         
     (d)  Additional Charge Adjustment.  As of January 1, 1993,
the Additional Charge shall be $0.0150/MMBtu and shall thereafter
be adjusted Quarterly during each Contract Year.  The Additional
Charge for an Adjustment Quarter shall be determined by
multiplying the previous Quarter's Additional Charge by the
Quarterly Adjustment Ratio for such Adjustment Quarter.  The
product of such calculation shall be rounded to four decimal
places.  If any information needed for the calculation of the
Quarterly Adjustment Ratio is not available until after the
beginning of an Adjustment Quarter, the calculation of the
Quarterly Adjustment Ratio shall be applied retroactively to the
beginning of such Adjustment Quarter.  Seller shall use all
reasonable efforts to provide Buyers with documentation to
substantiate the use of all calculations, whether
based upon estimated amounts or actual amounts, together with
supporting calculations and appropriate documentations, no later
than 30 days prior to the beginning of the Adjustment Quarter. 
An example calculation is shown on Exhibit H hereto.
     (e)  Procedure in the Event Indices are Discontinued or
Changed.  Buyers and Seller hereby agree that the indices used to
adjust the Price and Incremental Price are not intended to
reflect the changes in Seller's costs of providing Coal hereunder
or the change in the general market price for coal.  The sole
purpose in using the various indices is to afford the parties a
method whereby the Price and Incremental Price can be adjusted.
     If any index referred to in this Agreement is changed,
discontinued or unavailable for (i) four or more months out of
any two consecutive Quarters, if using monthly indices, or (ii)
two consecutive Quarters, if using Quarterly indices such that
the current index cannot be calculated, then the parties shall
undertake in good faith to agree upon a substitute index.  If an
index is only temporarily unavailable then said index shall be
calculated as provided for in Exhibit E attached hereto and
hereby made a part hereof or some other mutually agreed to
method.  If the base period of one or more of the indices used in
this Agreement changes, such indices will continue to be used,
but the index values used in the Prior Index calculation will be
changed to the index values for the new base period.
     Section 9.  Billing and Payment.
     (a)     Semi-Monthly Invoicing.  Each month, Seller shall
render two invoices and Buyers shall make two payments covering
the quantity of Coal delivered during such month.  Such quantity
shall
be determined using weights determined pursuant to Section 10
hereof and calorific value determined pursuant to Section 11
hereof.   The first invoice shall cover Coal delivered by Seller
during the first 15 days of the month and shall be mailed to
Buyers within five Business Days thereafter.  Buyers shall pay
the first invoice within nine Business Days of the date upon
which such first invoice is received.  The second invoice shall
cover Coal delivered by Seller from the 16th day to the last day
of the month and shall be mailed to Buyers within five Business
Days after the last day of the month.  Buyers shall pay the
second invoice within nine Business Days of the date upon which
such second invoice is received.  Invoices or credit memorandums
for retroactive price adjustments and other exceptional
circumstance shall be rendered by Seller as promptly as possible. 
Buyers shall make payment on such invoices within nine Business
Days of receipt of an invoice.
     (b) Monthly   Allocation   of Annual Base Quantity and
Incremental Quantity.   The Annual Base Quantity shall be
apportioned monthly by dividing the Annual Base Quantity by 365
and multiplying the result by the number of days in each month,
assuming that February always has 28 days in it.  The result for
each month shall be called the Monthly Base Quantity.  In any
month where the quantity of Coal shipped exceeds the Monthly Base
Quantity, the quantity of Coal which exceeds the Monthly Base
Quantity shall be deemed to be Incremental Quantity Coal.        
Such Incremental Quantity Coal shall be invoiced at the
applicable Incremental Price in the second invoice of each month
as provided in Section 9 (a) hereof.
     (c)  Annual True-up of the Annual Base Quantity.  The amount
paid by Buyers for the Annual Base Quantity shall be trued-up at
the end of each Contract Year if: (i) Buyers, during any Contract
Year, fail to take delivery of the Annual Base Quantity (less any
adjustments allowed pursuant to the terms of this Agreement) and
have been invoiced for Incremental Quantity Coal during the
Contract Year, Buyers shall pay to Seller the difference between
the Price and the Incremental Price, as the Price and Incremental
Price existed on December 31 of the Contract Year, multiplied by
the quantity of Incremental Quantity Coal invoiced by Seller
during such Contract Year pursuant to Section 9(b) above; or (ii)
Buyers, during any Contract Year, take delivery of more than the
Annual Base Quantity (less any adjustments allowed pursuant to
the terms of this Agreement) and the quantity of Coal invoiced by
Seller at the applicable Price during such Contract Year is less
than the Annual Base Quantity (less any adjustments allowed
pursuant to the terms of this Agreement), then Buyers shall pay
to Seller the difference between the Price and the Incremental
Price, as those Prices existed on December 31 of such Contract
Year, multiplied by the difference between the Annual Base
Quantity (less any adjustments allowed pursuant to the terms of
this Agreement) and the quantity of Coal invoiced by Seller at
the applicable Price during such Contract Year.  Seller shall
invoice Buyers for any amount to be paid under the provisions of
this Section 9(c) within 10 Business Days after the end of the
Contract Year.  Buyers shall pay such amount within 15 Business
Days after receipt of such invoice.  Example calculations of the
true-up are set forth in Exhibit N hereto.
     (d)  Method of Payment.  All payments required by this
Section 9 shall be made by electronic funds transfer via ACH in
U.S. currency for the invoiced amount to the account of Seller
numbered 72-51807 at Continental Illinois National Bank, ABA
Number 071-000039, Chicago, Illinois 60693 or any other bank and
account specified by Seller.
    Section 10.  Weights.
     (a)  Weights.   The weights of the Coal delivered hereunder
shall be determined on Seller's Scales at the point of delivery. 
The weights thus determined shall be accepted as the weight of
Coal for which invoices are to be rendered and payments made in
accordance with Section 9 hereof.  Seller shall furnish the
railroad transporting the Coal with copies of the weights thereby
determined in accordance with the rail tariff or contract in
effect at any given time.  Seller's Scales shall be inspected and
certified by the State of Wyoming or an entity mutually agreed
upon by Buyers and Seller at intervals of approximately six
months and Agent/operator shall be furnished with a copy of the
certification.  Seller shall use its best efforts to notify
Agent/Operator approximately 15 Business Days prior to any scale
inspection and certification.
     (b)  Missed Weights.  In the event that 50 percent or more
of the individual railcar weights from a unit train are available
from Seller's Scales, the average of the available railcar
weights from that unit train will be used for any unavailable
weights.  In the event that less than 50 percent of the
individual railcar weights from a unit train are available from
Seller's Scales, the average railcar weights from the previous 10
unit trains comprised of similar railcars from the same Coal
source shipped to the Energy Center will be used for any
unavailable weights.
     (c)  Weighing Audits and Adjustments.  Buyers shall have the
right to have a representative present at any and all times to
observe weighing of the Coal and inspection and certification of
Seller's Scales.  If any party should at any time question the
accuracy of Seller's Scales, such party may request a prompt test
of Seller's Scales at its expense by the State of Wyoming or an
entity mutually agreed upon by Agent/Operator and Seller.  If any
such test reveals an error in weight in excess of one and one-
half percent, then the weights of Coal shipped during one-half of
the period since the last preceding test shall be adjusted by the
amount of the error shown, an appropriate debit or credit
memorandum shall be furnished to Buyers by Seller and Seller's
Scales shall be promptly adjusted at Seller's expense.
     Section 11.  Sampling and Analysis.
     (a)  Sampling Procedure.  Coal to be delivered hereunder
shall be sampled at the Mine, Belle Ayr Mine or Alternate Source
Mine on a continuous basis:
      (i)  at the batch loading sampling system or
     (ii)  prior to ultimate loading into railcars.

     Such sampling shall be performed in accordance with methods
approved by ASTM, as the same may be supplemented or modified
from time to time, or by such other methods as may mutually be
agreed upon by Seller and Buyers.  Gross samples of Coal so taken
shall represent a unit train shipment; be representative of, and
identified as to, each shipment of Coal delivered hereunder to
Buyers; and be taken by equipment and in manners that meet the
requirements of ASTM Standard D2234 (Standard Test Methods for
Collection of a Gross Sample of Coal).  Sampling may also be done 
by Buyers at destination.  Buyers and Seller shall each have the
right to have a representative present in order to observe any
sampling and analysis done by the other and to take check samples
of the Coal.  All of Seller's samples shall be divided into three
parts in the manner specified by ASTM Standard D2013 (Standard
Method of Preparing Coal Samples for Analysis) and put into
suitable airtight containers.  One part shall be retained and
analyzed by Seller pursuant to applicable ASTM Standards; one
part shall be delivered to Agent/Operator or Buyers' designee by
mutually agreeable means and analyzed by Buyers pursuant to
applicable ASTM Standards; and the third part shall be retained
by Seller in one of the aforesaid containers, properly sealed and
labeled, for not less than 30 days after the last day of the
month in which the sample was taken, to be analyzed if a dispute
arises due to a difference between Buyers' and Seller's analysis.
     (b)  Analysis Procedures.  Seller shall perform a "short
proximate" (for moisture, ash, sulfur and gross calorific value)
analysis and any other analyses mutually agreed upon for each
shipment as soon as practicable upon completion of loading and
shall notify Agent/Operator of the results thereof prior to
receipt of the Coal at the Energy Center.  The analysis methods
for moisture, ash, sulfur, gross calorific value and coal size
designation shall be performed in accordance with ASTM Standards
D3302 (Standard Test Method for Total Moisture in Coal), D3174
(Standard Test Method for Ash in the Analysis Sample of Coal and
Coke from Coal), D4239 (Standard Test Methods for Sulfur in the
Analysis Sample of Coal and Coke Using High Temperature Tube
Furnace Combustion Methods), D3286 (Standard Test Method for
Gross Calorific Value of Coal and Coke by the Isoperibol Bomb
Calorimeter) and D4749 (Standard Test Method for Performing the
Sieve Analysis of Coal and Designating Coal Size).  The procedure
for determining grindability shall be agreed to in writing by
Buyers and Seller.  Each party hereto shall assume the cost of
all sampling and analyses performed by it.  The analysis of the
third part of any sample, should its analysis be found necessary,
shall be made by an independent commercial testing laboratory
(pursuant to applicable ASTM Standards), mutually chosen, and the
results of such analysis shall be controlling.  The cost of the
analysis made by such commercial laboratory shall be shared
equally by Seller and Buyers.
     (c)  Analysis Reports.  Seller shall mail copies of each
shipment analysis and monthly analyses to Agent/Operator as
completed and, further, shall furnish a monthly report to
Agent/Operator, including a summary of the individual shipment
analyses and weights serving as the basis for invoicing.        
Such analyses shall be deemed acceptable and binding unless
protested by Agent/Operator within 30 days after receipt of the
applicable monthly report.
     Section 12.  Records and Audits.
     (a)  Recordkeeping. Seller shall keep accurate and
satisfactory records and books of account in compliance with
generally accepted accounting principles showing all weights and
analyses of Coal, costs, payments, invoices, and/or revisions,
adjustments, credits, debits pertaining to Price, Incremental
Price, Deficient Quantity Charge, Additional Charge and annual
true-up of Annual Base Quantity pursuant to Section 9(c) hereof
and
all other information and data required for the purposes of this
Agreement ("Records").
     (b)  Records' Revisions - Calculations.  Each time the
Records are revised in accordance with this Agreement and at any
other time upon 30 days' notice in writing from Buyers, Seller
shall furnish to Buyers a detailed statement showing the
revisions and/or calculations of the Records and the basis
thereof.
     (c)  Right to Audit.  At all reasonable times,
Agent/operator shall have the right to have the applicable
Records audited at Agent/Operator's expense for the purpose of
verifying all Records.  Such audit shall be mutually scheduled at
least 30 days prior to the start of the Audit.
     (d)  Right to Audit Invoiced Items.  The Invoiced Items
shall consist of the Price, Incremental Price, Deficient Quantity
Charge, Additional Charge and any annual true-up payment.       
The Invoiced Items shall be binding upon Buyers unless the audit
is completed, the written audit report is submitted to Seller,
and Buyers take exception to said Invoiced Items within one year
of the end of the Contract Year in which any change was made to
an Invoiced Item.  At Agent/Operator's option any audit shall be
made:
          (i) by the nationally recognized firm of certified
              public accountants as shall then be
              retained by Seller or Buyers or;

              (ii) by Buyers' internal audit staffs.


     Such audit report shall set forth, in reasonable detail, all
data necessary to verify any such adjustments of the Invoiced
Items.    Any errors made by Seller in making such adjustments as
disclosed by any such audit shall be promptly corrected by making
appropriate retroactive changes, except that claimed errors
resulting from an interpretation of this Agreement by such
auditors
not agreed to by Seller's General Counsel shall be subject to
resolution pursuant to Section 16 hereof.
     Section 13.  Force Majeure.
     (a)  Defined.  As used herein, the term "Force Majeure shall
mean any and all causes beyond the control and without fault or
negligence of the party affected thereby, including, without
limitation, acts of God, acts or orders of public authorities
(including civil and military authorities and courts of competent
jurisdiction) , acts of the public enemy, embargoes,
insurrections, riots, labor disputes, labor or material
shortages, fires, explosions, floods, river freeze-ups,
breakdowns of or damage to plants, equipment or facilities
(including emergency outages of equipment or facilities to make
repairs to avoid breakdowns thereof or damage thereto) which
wholly or partially prevent or interfere with the mining,
hauling, processing or loading of Coal by Seller or the
receiving, transporting and/or delivering by the carrier thereof,
or the utilizing thereof by Buyers.
     (b)  Effect Hereunder.   If, because of Force Majeure, any
party hereto is unable to carry out any of its obligations under
this Agreement (other than the obligation of a party to pay money
in connection with the performance of this Agreement), and if
such party shall promptly give to the other parties concerned
written notice of such Force Majeure, then the obligation of the
party giving such notice shall be suspended to the extent made
necessary by such Force Majeure and during its continuance;
provided, the party giving such notice shall use its best efforts
to eliminate the cause of such Force Majeure insofar as possible
with a minimum of delay; provided further, any party shall have
the right to
settle or resolve any labor dispute with its employees in its
sole discretion.  The parties receiving notice shall, within 30
days, accept or reject the claim of Force Majeure; provided, such
party shall have been afforded reasonable time and access to
appropriate personnel and records to investigate the Force
Majeure.
     (c)  Deficiencies in Delivery.  Any deficiencies in delivery
of Coal hereunder caused by a Force Majeure which are related to
the transportation of Coal from the Mine, Belle Ayr Mine or
Alternate Source Mine to the Energy Center, except where Buyers
have received notice from the rail carrier transporting Coal that
it has incurred a Force Majeure under the rail tariff or
contract, shall be made up as soon as possible unless such Force
Majeure has a duration of 7 or more consecutive days in which
case only that part of the deficiency related to the first 7 days
of such Force Majeure will have to be made up.  All other
deficiencies in deliveries of Coal hereunder caused by Force
majeure shall not be made up except by mutual consent.  Any
quantity of Coal that would have been shipped during a period of
Force Majeure shall be credited against the Annual Base Quantity
of Coal (by an amount equal to the product obtained by
multiplying the number of days of such suspension by the result
obtained by dividing the Annual Base Quantity by 365).  In the
event Force Majeure causes only a partial reduction in the total
quantity of Coal Seller can deliver, Seller shall deliver to
Buyers its pro rata share of the coal produced from the Mine,
Belle Ayr Mine or Alternate Source Mine, if applicable, during
the continuance of such partial reduction.
     (d)  Rights to Suspend and Purchase and/or Sell to Others. 
Either party hereto shall have the right to elect to suspend the
purchase or sale of Coal, as the case may be, for the period of
time during which such Force Majeure may exist, and Buyers, if
they so elect, in the case of an event of Force Majeure (i)
declared by Seller without regard to duration or (ii) caused by
the inability of Buyers' contract rail carrier(s) to transport
Coal from the Mine, Belle Ayr Mine or Alternate Source Mine to
the Energy Center for a period of 14 or more consecutive days,
shall have the right during such period to purchase coal from
other sources and Seller, if it so elects, shall have the right
during such period to sell coal to others.  The quantity of coal
so purchased from other sources shall be credited against the
Annual Base Quantity 
     If Buyers suspend shipments pursuant to this Section 13,
then the Annual Base Quantity shall be reduced by an amount equal
to the product obtained by multiplying the number of days of such
suspension by the result obtained by dividing the Annual Base
Quantity by 365.
     (e)  Right to Terminate Agreement.  Notwithstanding the
foregoing, in the event the party which gave notice of an event
of Force Majeure which has caused such party to be unable to
comply substantially with such party's obligations hereunder has
not substantially eliminated such Force Majeure within 12 months
after so notifying the other party, such other party shall have
the right, at its option, to terminate this Agreement without any
penalty by notifying the party which gave such notice of Force
Majeure of its election to do so.  Any such termination shall be
effective 30 days after the giving of such notice.
     (f)  Exception to Force Majeure.  Notwithstanding the
foregoing provisions of this Section 13, it is expressly
understood that any prohibition to take deliveries of, or to
utilize Coal subject hereto, which is imposed upon Buyers by
means of laws, regulations or orders of a court or administrative
body, whether or not such event is beyond the control of Buyers,
shall not for the purposes herein negate the provisions set forth
in Section 15 hereof.
     Section 14.  Relief From Economic Hardship.
     (a)  Notice Required.  Seller and Buyers acknowledge the
possibility of either party sustaining an economic hardship under
this Agreement because of conditions which were unforeseeable on
January 1, 1993.  At any time either party believes it has
sustained an economic hardship under this Agreement and wishes to
invoke the provisions of this Section 14 to obtain relief, if
any, it shall give notice in writing to the other party setting
forth documentary proof of the following:
          (i)  the existence, nature, cause, extent and impact of  
              such economic hardship; and

         (ii)  the facts establishing that the conditions causing
               such economic hardship were unforeseeable.


     The party sending such notice shall also state the relief
which it considers reasonable and appropriate to eliminate such
economic hardship.
     (b)  Consideration of Request.  Upon receipt of the notice
set forth above, the' party receiving such notice shall consider
the documentary proof submitted and any other relevant matters,
and if (subject to the provisions of section 14(c) hereof), it,
in its judgement, finds that the party sending such notice has
sustained an economic hardship due to the cause stated in such
notice and is entitled to relief hereunder, the party receiving
such notice shall give reasonable and appropriate relief to the
party sustaining the economic hardship.  The party receiving such
notice shall not arbitrarily refuse to find that the other party
has sustained an 
economic hardship nor arbitrarily deny reasonable and appropriate
relief to eliminate such hardship if found to exist.

     (c)  Exceptions.  Economic hardship arising from any of the
following types of causes or conditions shall not be grounds for
relief hereunder:
          (i)   where the cause or condition is provided for in  
                this Agreement;
          (ii)  where the cause or condition results from a matter
                involving the internal operations of the party
                claiming that it has sustained an economic
                hardship;

          (iii) changes in the market for coal resulting from
                competitive factors;
          (iv)  availability or costs of alternative fuels; or
           (v)  the prohibition to take deliveries of, or to
                utilize the Coal subject hereto, the effect of    
           which is provided for in Section 15 hereof.

     (d)  Effect of Refusal.  If the party receiving a request
referred to in Section 14(a)  hereof, (i) elects to negotiate
regarding the matters set forth in such request but an
appropriate amendment of this Agreement regarding such matters
has not been fully executed within 90 days following the date of
such request, or (ii) refuses to agree to or negotiate regarding
such matters, then the party which made such request may, with
the concurrence of the other party, submit such matters to
arbitration pursuant to Section 16 hereof or, if the other party
does not agree to submit such matters to arbitration hereunder,
exercise any other right or remedies available to it at law or in
equity.
     Section 15. Compliance with Anti-Pollution Laws and
Regulations, etc.
     (a)  Termination Charge.  The parties hereto recognize that,
during the Term, legislative, administrative or regulatory bodies
or courts having competent jurisdiction over the subject matter
herein may enact laws, regulations, or issue orders such as, but
not limited to, those relating to air pollution, the effect of
which will make it impossible or impractical for Buyers to
utilize the Coal subject hereto without substantially changing or
altering its utilization, equipment or transportation to the
Energy Center.  Any such laws, regulations or orders may pertain
to, but would not necessarily be limited to, sulfur content of
the Coal.  If any such laws, regulations or orders are imposed
and, as a result thereof, Buyers, in their sole judgment, decide
that it will be to their best interest not to utilize the Coal
subject hereto, notwithstanding the provisions of this Agreement
to the contrary, Buyers shall have the right to terminate this
Agreement; provided, before Buyers can terminate this Agreement
pursuant to this Section 15, Buyers and Seller shall meet to
attempt to develop a plan that would allow Buyers to continue to
utilize the Coal under this Agreement.  Seller shall pay all
costs to develop any plan contemplated by this Section 15,
including, but not limited to, any professional services incurred
by Buyers.   The plan design and costing shall be approved by
Buyers in their sole discretion.  The plan design, development
and implementation cost shall be paid by Seller, in its sole
discretion.  If Seller refuses to pay the total plan design,
development and implementation cost, then Buyers may terminate
this Agreement pursuant to this Section 15; provided, Buyers
agree to pay Seller an annual termination charge
("Termination Charge") for the remaining life of this Agreement. 
The Termination Charge shall be equal to $0.0120 per MMBtu
multiplied by the Annual Base Quantity.  During any period in
which Buyers are obligated to pay the Termination Charge, Seller
shall use its reasonable efforts to sell the Coal which Buyers
are obligated to purchase hereunder to others.
     (b)  Termination Charge Reduction.  After Seller has shipped
all of the coal contracted from the Mine to others in any
Contract Year, should Seller sell any of the Coal which Buyers
were obligated to purchase hereunder during said Contract Year to
others at a sales price, which is greater than the Price that
would have been in effect for such Contract Year, then, the
Termination Charge shall be reduced by an amount equal to the
product of the difference between such sales price and Price
multiplied by the quantity of such coal sold to others.
     (c)  Termination Charge - Effect of Other Contracts.  In the
event there are other agreements for coal produced at the Mine
that contain a similar termination charge that are also
terminated, the portion of said contracted quantity that is sold
shall be prorated.  Said credits are to become effective for all
coal sold over and above the total unaffected portion of the
Mine's contracted annual production.  During any period in which
Buyers are obligated to pay the Termination Charge, Seller shall
use its reasonable efforts to sell the entire output of the Mine
to others.
     (d)  Termination Charge - Seller's Obligation/Buyers'
Recourse.    Rejection by Seller of a bona fide offer to purchase
coal at a price at least equal to that which would then be
currently effective under this Agreement shall relieve Buyers of
their obligation to pay the Termination Charge attributable to
said
quantity.  Seller shall keep Buyers informed as to offers and
sales of said coal.
     Section 16.  Arbitration.
    (a)  Pre-Arbitration Procedure.  With respect to any
controversy, claim, counterclaim, dispute, difference or
misunderstanding arising out of or relating to the interpretation
or application of any term or provision of this Agreement
("Dispute") any party may provide written notice to all the other
parties by certified mail, return receipt request ("Notice") of
the existence of a Dispute.  The parties shall for a period of 30
calendar days following the date of the Notice that a Dispute
exists engage in good faith discussions and negotiations in an
attempt to resolve such Dispute.   If, by the end of such 30 day
period, unless such period is extended by mutual agreement of the
parties, the parties have been unable to resolve such Dispute,
they shall have a period of 15 calendar days to mutually agree to
arbitrate such Dispute pursuant to the procedure set forth below. 
If, at the end of such 15 day period the parties have not
mutually agreed to arbitrate such Dispute, then such Dispute may
be resolved in any federal or state court located in the State of
Colorado or the appellate courts thereof.
     (b)  Arbitration Procedure.  Any arbitration hereunder shall
be subject to and conducted pursuant to the procedures set forth
in the Rules for Commercial Arbitration of the American
Arbitration Association and the Federal Arbitration Act;
provided, the parties shall agree prior to arbitration as to
whether or not the arbitration award or decision shall be binding
upon the parties.

electronic communications or orally to such agent of the party
hereto being notified as may be appropriate and, if given by

production, sale and delivery of Coal subject hereto and
activities relating to a New Law in Section 8(c) hereof shall, at

upon the parties hereto and their respective successors and
assigns; provided, this Agreement may not be assigned by either

claim that any Action brought in any Court has been brought in an
inconvenient forum, and (iii) any objection, with respect to any
