COAL SUPPLY AGREEMENT

    THIS AGREEMENT is made and entered into this 25th day of August, 1995, by 
and between Kennecott Energy Company, a Delaware corporation, with offices in 
Gillette, Wyoming, for and on behalf of Spring Creek Coal Company, a Montana 
corporation (hereinafter together called "Seller"), and American Crystal 
Sugar Company, a Minnesota cooperative with offices at 101 North Third 
Street, Moorhead, Minnesota 56560 ("Buyer").

                                       RECITALS

    1.   Spring Creek Coal Company and Buyer entered into a Coal Supply
Agreement dated August 1, 1986 ("the 1986 Coal Supply Agreement") relating to
the supply of coal to July 31, 1995.

    2.   Buyer desires to secure a continued coal supply for use in the
operation of its sugar factories in East Grand Forks, Moorhead and Crookston,
Minnesota, and in Drayton and Hillsboro  North Dakota, and, at its option, at
the ProGold Limited Liability Company ("Progold LLC") (a 46% owned affiliate of
Buyer) Wahpeton, North Dakota corn processing factory referred to collectively
as the "Sugar Factories" or individually as a "Sugar Factory," from 1995 for a
period of ten (10) years.




    3.   Seller desires to continue to sell to Buyer coal to be mined from its
Spring Creek Mine (the "Mine") near Decker, Montana.

    NOW, THEREFORE, in consideration of the mutual covenants and agreements of
the parties set forth below, Seller agrees to sell and deliver, and Buyer agrees
to purchase and accept, coal of the quantity and quality specified below, at the
price and on the terms and conditions stated in this Agreement.

    SECTION 1.      TERM; CAMPAIGN SEASONS.

    1.01 TERM.  The term of this Agreement shall commence on August 1, 1994
("the Effective Date") and shall continue up to July 31, 2005.

    1.02 CAMPAIGN SEASONS.  Shipments to all sugar factories except ProGold LLC
under this Agreement are to be divided into periods of approximately ten months
commencing on or about.  August 15 and continuing until about May 31 of the
following calendar year, with the last such period running from about August 15,
2004, to about May 31, 2005.  These ten-month periods of coal deliveries shall
be referred to as "Campaign Seasons." Shipments to ProGold LLC may occur
year-round.

    SECTION 2.      COAL SOURCE.

    The coal sold under this Agreement shall be from Seller's
    Spring Creek Mine located near Decker, Montana.  If an event of


                                          2


force majeure, as defined in Section 8, prevents delivery of coal at the Spring
Creek Mine, Seller may, but shall not be required to, supply coal from sources
other than the Spring Creek Mine ("Substitute Coal"), provided that the price
for Substitute Coal shall be adjusted as necessary so that the total delivered
cost per million Btu for Substitute Coal delivered to the Sugar Factories,
taking into account Buyer's actual transportation costs, equals the delivered
cost per million Btu for coal from the Mine, subject to any price adjustments
pursuant to Sections 4.02 and 6.01. Seller's right to furnish Substitute Coal
shall not affect its right to claim a force majeure or to claim excuse from
performance pursuant to Section 8 below.  Buyer may, but shall not be required
to, accept Substitute Coal with field averages different than Spring Creek Mine
field averages specified in Section 4.01 (a) of this Agreement.

    SECTION 3.     COAL QUANTITY; SHIPMENT SCHEDULE.

         3.01      QUANTITY.  Seller agrees to sell and Buyer agrees to 
purchase  all of the coal (other than up to 6,500 tons of Buyer's total coal 
requirement in each Campaign Season, which amount Buyer may utilize for test 
coal burns) that Buyer requires to operate its Sugar Factories during the 
term of this Agreement, which Buyer in good faith estimates to be 500,000 
tons per

                                          3


Campaign Season.  The term "ton" shall mean 2,000 pounds of coal, weighed as
provided in Section 5.04(b) below.

    3.02      ESTIMATES.

         (a)  CAMPAIGN SEASON ESTIMATES.  Upon execution of
this Agreement and by August 1 of each subsequent year, Buyer shall furnish
Seller with a written estimate of the quantity of coal to be delivered FOB
Seller's Mine during the Campaign Season beginning in that year.

         (b)  CHANGES TO ESTIMATES.  If Buyer desires to alter the quantity of
coal to be delivered FOB Seller's Mine during a Campaign Season, Buyer may 
notify Seller by mail or by telephone, telegraph or other electronic means.  
Any electronic notice shall be confirmed in writing within ten (10) days.  
For purposes of this Section 3.02, the total amount of coal requested by 
Buyer for a Sugar Factory during any period shall be calculated by the 
following formula:

    [(Lp divided by Lcs) x Ecs] + A = Coal Requested

    where

    Lp =      Length of the actual delivery period within the Campaign Season,
              in days
    Lcs =     Length of the Campaign Season, in days
    Ecs =     Estimate of coal requirements for that Sugar Factory for the
              Campaign Season
    A   =     Adjustments.  The term "Adjustments" shall mean the sum of all
              increases or decreases in coal


                                          4


         deliveries during the given period requested by Buyer.

         (c)  EXTENSION OF CAMPAIGN SEASON.  For all sugar factories except
ProGold LLC, Buyer may extend any Campaign Season by three months before August
15 or after May 31 of such Campaign Season upon six weeks' written notice to
Seller.  Campaign season for ProGold LLC is contemplated to be year-round.

    3.03 SHIPMENTS.  Buyer shall use reasonable efforts to schedule arrivals of
trains at Seller's Mine such that Seller can deliver coal in approximately equal
monthly amounts during any Campaign Season; provided that deliveries in the
first months of a Campaign Season will be larger to allow Buyer to build
stockpiles at each Sugar Factory.  Weekly deliveries will be in substantially
equal quantities consistent with the monthly delivery quantity.  Seller shall
use reasonable efforts to deliver as much coal as Buyer desires to take in any
week.  Buyer agrees to pay for and accept delivery of up to 12 percent more than
Buyer's estimated or amended coal requirements in any month, provided that Buyer
shall not be required to pay for more coal than it has requested during any
Campaign Season.

    SECTION 4.     QUALITY OF COAL.

         4.01      QUALITY AND SIZE OF COAL.

               (a)  FIELD AVERAGES.  Field averages for Spring Creek Coal are
as follows:


                                          5



         Btu:                9,400 per pound
         Sulfur:             0.33 percent
         Sodium oxide:       8.39 percent
         Ash:                4.00 percent
         Moisture:           24.50 percent
         Size:               run-of-mine, sized to pass through two-inch round 
                             screen (crushed 2" x 0)

Buyer acknowledges that actual quality of particular coal shipments will vary as
different portions of the field are mined.  Buyer's exclusive remedies for
variations from field averages are those set forth in Section 4.02 below.

         (b)  SAMPLING.  Representative samples of coal f rom each trainload
shall be taken at the loading facilities at Seller's Spring Creek Mine by agents
of an independent commercial testing organization, using methods and procedures
approved by the American Society for Testing and Materials (ASTM).  The
resulting analysis shall be accepted as the quality of coal on which invoices
are to be rendered and payments made in accordance with Section 6. Any change in
the quality of coal during subsequent transportation or storage shall have no
effect on the quality of coal as shown on the invoice.

    4.02      REMEDIES FOR QUALITY VARIATIONS.  Buyer may not reject any
trainload of coal once the coal has commenced loading onto railcars at the Point
of Delivery as defined in Section 5.01. The following remedies shall be Buyer's
exclusive



                                          6


remedies for variations in the quality of coal delivered under this Agreement.

         (a)  BTU/LB.  If any five consecutive trainloads of coal contain a
cumulative weighted average Btu/lb less than 9200 Btu/lb, then the Purchase
Price of the fifth and each consecutive trainload that, when averaged with the
previous four trains, maintains a weighted average Btu/lb less than 9200 Btu/lb
("low Btu coal") shall be adjusted according to the following formula:

    Weighted Average Btu content per pound-9200
    (for five consecutive trainloads)                      x Purchase
    ------------------------------------------                Price
                   9200

    If any five consecutive trainloads of coal contain a cumulative weighted
average Btu/lb greater than 9600 Btu/lb, then the Purchase Price of the fifth
and each consecutive trainload that, when averaged with the previous four
trains, maintains a weighted average Btu/lb greater than 9600 Btu/lb ("high Btu
coal") shall be adjusted according to the following formula:


    Weighted Average Btu content per pound - 9600
    (for five consecutive trainloads)                      x Purchase
     -------------------------------------------              Price
                   9600





                                          7




         (b)(i)    SULFUR DIOXIDE.  If delivered coal cannot
be burned at the Sugar Factory to which it is shipped because the cumulative
weighted average sulfur dioxide content of any five consecutive trainloads of
coal exceeds 1.2 pounds per million Btu of sulfur dioxide, Buyer shall have the
following remedies:

              (aa)      Buyer may, at its option, reconsign all segments of the
fifth and each consecutive trainload that maintains a cumulative weighted
average in excess of 1.2 pounds per million Btu of sulfur dioxide at Seller's
expense to a Sugar Factory that can burn such coal, or

              (bb)      If Seller cannot cure the problem within seven (7) days
by providing Substitute Coal or otherwise, Buyer may discontinue coal purchases
(as to any unit train that has not commenced loading) with respect to the
affected Sugar Factory.  Reduction in tonnage to the affected Sugar Factory
shall be Buyer's sole remedy per this Section (b) (i)  (bb), and Seller shall
not be liable for any incidental or consequential damages, including lost
profits, caused thereby.

              (ii)      In the case of shipments of coal to the East Grand
Forks Sugar Factory, Seller shall use its reasonable efforts to deliver a
cumulative weighted average sulfur dioxide content of any five consecutive
trainloads of coal not exceeding 0.65 pounds sulfur dioxide per million Btu.


                                          8



              (iii)     In the case of shipments of coal to the Crookston Sugar
Factory, Seller shall use its reasonable efforts to deliver a cumulative
weighted average sulfur dioxide content of any five consecutive trainloads of
coal not exceeding 0.93 pounds of sulfur dioxide per million Btu.

         (c) SODIUM OXIDE, MOISTURE AND ASH.  With respect to sodium oxide,
         moisture and ash content, Buyer assumes the risk of all variations
         from field averages.

    SECTION 5.    UNIT TRAINS, LOADING AND WEIGHING.

         5.01      POINT OF DELIVERY.   The coal for the Sugar Factories 
shall be delivered FOB loaded in railcars provided by Buyer on the railroad 
loading siding at the Mine or, if Substitute Coal is delivered to any Sugar 
Factory, at the railroad loading siding located at the Substitute Coal Source 
(the "Point of Delivery"), with freight paid by Buyer.

         5.02      TITLE.  Upon the completion of loading of a railcar, the
title and risk of loss for all coal in that car shall be Buyer's.

         5.03      TRAINS.  Buyer shall provide trains of no fewer than 55
open-top hopper or gondola railcars each.  Such railcars shall be delivered to
the Point of Delivery by Buyer, ready for loading, with hopper doors closed and
cleaned of all previous commodities.


                                          9



         5.04      LOADING PROCEDURE.

              (a)  OPERATIONS.  Buyer shall be responsible for arranging all
transportation contracts and for coordinating the arrival of railroad trains for
loading at the Point of Delivery with Seller.  Buyer or its designee shall use
best efforts to give Seller at least 24 hours' notice of the arrival of railcars
at the Point of Delivery for loading.  Seller shall operate its railcar loading
facilities twenty-four (24) hours per day, three hundred sixty-five (365) days
per year, subject to Seller's labor agreements.  Seller shall, at its expense,
load each railcar to its full visible capacity and will complete the loading of
each train, including authorization of the train's departure.  Seller will hold
Buyer harmless from any damages caused by the overloading of railcars.

              (b)  WEIGHING.  The weight of coal sold under this Agreement
shall be determined on appropriate commercial scales chosen by Seller and
installed at Seller's loading facilities at the Spring Creek Mine.  Seller's
scales shall be inspected and certified by Hoke and Associates at six-month
intervals during the term of this Agreement.  The weights determined at Seller's
Spring Creek Mine shall be accepted by Buyer as the quantity of coal for which
invoices are to be rendered and payments made in accordance with Section 6
below.  Any change in the weight of



                                          10


coal during subsequent transportation or storage shall have no effect on the
weight of coal shown on the invoice.  In the event Seller's scales are
inoperative for a period, Seller shall inform Buyer and use its best efforts to
restore operation of the scales as soon as possible.  The weight of coal per
railcar delivered during such period that scales are inoperative shall be
deemed equal to the average weight per railcar for coal delivered during the
preceding month.  If Seller's scales are inoperative during the first month of
this Agreement, the weight of coal delivered shall be determined by mutually
acceptable independent means.

         SECTION 6.      PRICE; PRICE ADJUSTMENTS.

         6.01      PURCHASE PRICE. The Purchase Price per ton of coal (2,000 
pounds) to be paid by Buyer, or by Buyer on behalf of ProGold LLC, to Seller 
for each delivery of coal FOB Point of Delivery in railcars under this 
Agreement shall be the sum of (a) the Base Price, as defined and as adjusted 
as provided below, plus (b) the Pass-Through Costs, as defined in Section 
6.04, plus (c) the New Costs, as defined in Section 6.05, applicable to such 
delivery. The Purchase Price, as thus determined, shall be subject to 
adjustment for changes in the depletion allowance as provided in Section 
6.06, and for Btu Variations as provided in Section 4.02.


                                          11

                                             *CONFIDENTIAL TREATMENT REQUESTED*

    As of the Effective Date, the initial Base Price per ton of coal FOB 
Point of Delivery is equal to ** (the "Initial Base Price"), the Pass-Through 
Costs are equal to ** and the Purchase Price is therefore equal to ** per 
ton.  The Purchase Price per ton of coal delivered by Seller to Buyer or to 
ProGold LLC during the Campaign Season from August 1994 to May 1995 ("the 
Campaign Season 1994-95"), shall be adjusted from the Purchase Price to be 
paid by Buyer for such coal delivery pursuant to the 1986 Coal Supply 
Agreement to the Purchase Price referred to in this Section 6.01. Such 
adjustments in Purchase Price for deliveries of coal already made during the 
Campaign Season 1994-95 to the date of this Agreement shall be paid or 
credited to Buyer in accordance with Section 6.08 hereof.

         6.02      INDEX ADJUSTMENT OF BASE PRICE.  The Initial Base Price as 
of the Effective Date shall be divided, for purposes of escalation, into 
three Initial Base Price Components, weighted in percentage terms as follows: 
(1) Gross Domestic Product-Implicit Price Deflator (GDP-IPD Component: 40%); 
(2) SIC Code 122 (Labor Component: 30%); and (3) PPI 112 (Machinery 
Component: 30%).  The Initial Base Price values are set forth as follows:

    GDP - IPD = First published, first quarter 1994 value
    (125.7) [Source: Department of Commerce, Bureau of
    Economic Analysis] as published in the April 1994

                                      12


    monthly report, "Survey of Current Business", Table 7.13.

    SIC 122 = First published, May 1994 value (17.85) [Source: U.S. 
    Department of labor, Bureau of Labor Statistics] as published in the 
    July 1994 monthly report, "Employment & Earnings" currently in Table B-15.

    PPI - 112 = First published, June 1994 value (133.6) [Source: U.S. 
    Department of Labor, Bureau of Labor Statistics] as published in the 
    June 1994 monthly report, "Producer Price Indexes", currently in Table 6.

    The Initial Base Price will apply to all shipments of coal made during the 
Campaign Season 1994-1995 and all shipments thereafter through September 30, 
1995.

    The Initial Base Price will be adjusted on the first day of each 
calendar quarter during the term of this Agreement, beginning October 1, 
1995.  The Initial Base Price, as adjusted, will be referred to as the "Base 
Price".  These adjustments will be calculated as follows using the most 
current first published index information available at the beginning of each 
quarter:

 ABP =  |.4 x (AG) +.3 x (AL) +   .3 x (AM)   |x IBP
        |    -------    ------        ------- |
        |    (125.7)    (17.85)       (133.6) |
where,

      ABP = Adjusted Base Price for the current calendar quarter.

      AG =  GDP/IPD first published index value for the second preceding 
            quarter.

      AL =  SIC 122 AHE first published index value for the third preceding 
            month.

                                      13



      AM = PPI - 112 first published index value for the second preceding
           month.

      IBP = The Initial Base Price as referred to in Section 6.01.

         6.03      CHANGES IN INDICES.  Should any of the indices  referred 
to in Section 6.02 above be discontinued, the parties shall select a 
substitute index or indices by mutual agreement.

         6.04      PASS-THROUGH COSTS.  Seller's costs per ton of coal 
produced and delivered, falling into the categories below, shall be treated 
as "Pass-Through Costs" fully reimbursable by Buyer to Seller over and above 
the Base Price determined under Sections 6.01 and 6.02. The amounts set forth 
in attached Exhibit A are the amounts that will be included in the Purchase 
Price as of August 1, 1994, for each Pass-Through Cost Item.  Pass-Through 
Costs, other than pass through costs assessed on values relating to the sales 
price, shall be prorated over the total volume of Seller's production from 
the Mine, and Buyer shall be assigned, as its actual Pass-Through Costs, only 
that prorated share based on Buyer's share of the total of Seller's 
production from the Mine.  Buyer shall receive a refund or credit against 
future purchases (if applicable) in the event Seller receives a reduction in 
or refund of any Pass-Through Costs charged to Buyer.  The categories of 
Pass-Through Costs are more specifically defined as follows:

                                      14


              (a)  TAXES AND BLACK LUNG COSTS.  All taxes and black lung 
costs (other than taxes directly borne by Buyer or taxes imposed on or 
measured by net income and franchise taxes) levied or assessed by any 
governmental authority on the coal, on its severance from the soil, or on 
Seller's mining facilities or operations or other activities incident to the 
performance of its obligations under this Agreement, including all taxes and 
governmental charges levied or assessed against Seller with respect to the 
coal for reclamation by any governmental authority; taxes imposed pursuant to 
26 USC Section 4121 or other successor provision of law, or other taxes that 
may be imposed to provide health or safety benefits to Seller's employees; 
and all costs, other than taxies, incurred by Seller in connection with 
production of coal at the Mine for black lung, including (without limitation) 
premiums for black lung insurance, or payments made or accrued to a private 
or public trust (including a trust fund established pursuant to Section 
501(c) (21) of the Internal Revenue Code) or reserve for future black lung 
claims.  In the event Seller chooses to cover its potential black lung 
liability by a means other than black lung insurance, the amount included as 
black lung costs under this provision shall not exceed the cost of such 
insurance.  Buyer is to bear and pay directly (or reimburse Seller for any 
such taxes Seller pays) all sales, use,

                                       15


or similar taxes levied or assessed on the coal purchased hereunder.  The 
parties agree that if taxes are assessed on values related to the sales 
price, taxes paid by Buyer under this Agreement shall be computed using the 
Purchase Price under this Agreement.

              (b)  ROYALTIES.  All royalties in effect on the coal sold to 
Buyer and for which Seller is liable under the leases then prevailing, 
notwithstanding suspension of payment pending any appeal of the royalty or 
adjustment thereof.  In the event any royalty or adjustment is appealed by 
Seller and decreased as a result, Seller will refund to Buyer any 
overpayments.  The amount of royalties to be paid by Buyer as to any month's 
deliveries of coal mined under leases held by Seller ("Leased Coal") shall 
equal the applicable royalty per ton multiplied by the number of tons of 
Leased Coal delivered to Buyer from the Mine during that month.  If royalties 
are assessed on values related to the sales price, royalties paid by Buyer 
under this Agreement shall be computed using the Purchase Price under this 
Agreement.

         6.05      NEW COSTS.  The Base Price provided in Section 6.01 
includes Seller's best estimate of the cost, per ton of coal, of complying 
with all federal, state, and local laws, rules, and regulations in force as 
of July 1, 1994, except for

                                      16

those items specifically designated as Pass-Through Costs, as they were 
implemented, interpreted, and enforced on the Effective Date, which estimate 
shall, for purposes of this provision, be binding upon Seller (such costs 
shall be referred to as "Compliance Costs") . To the extent that new laws, 
rules, regulations, or governmental orders coming into effect after July 1, 
1994, or changes in the implementation, interpretation or enforcement of 
laws, rules and regulations in effect on July 1, 1994, cause any increase or 
decrease in the Compliance Costs, the Purchase Price shall be increased or 
decreased, as the case may be, by the amount that accurately reflects the 
change in Compliance Costs incurred.  Such changes in Compliance Costs shall 
be referred to as "New Costs."

    New Costs shall be prorated over the total volume of Seller's production 
from the Mine if the new cost is based on tonnage sold from the Mine, and 
Buyer shall be assigned, as its actual New Costs, only that prorated share 
based on its share of the total of Seller's production from the Mine.  If the 
New Cost is based on a percentage of Sales Price, Buyer shall pay its portion 
of the new cost based on its Sales Price.

         6.06      ADJUSTMENT OF PURCHASE PRICE FOR CHANGES IN DEPLETION 
ALLOWANCE.  If at any time after the Effective Date changes are made in the 
law regarding the allowance for depletion

                                      17

                                             *CONFIDENTIAL TREATMENT REQUESTED*

on coal that affect the state and federal income tax deductions for depletion 
available to Seller, the Purchase Price shall be increased or decreased by 
the amount needed to provide Seller with the same cash flow from the sale of 
each ton of coal under this Agreement after state and federal income taxes.  
In calculating Seller's after-tax cash flow from the sale of a ton of coal 
for this purpose, Seller shall compute its taxes as if it filed separate 
(nonconsolidated) state and federal income tax returns and paid state and 
federal income taxes at the maximum rate for corporations.

         6.07      BILLING AND PAYMENT.  Seller shall invoice Buyer 
semimonthly for coal delivered.  Payment shall be made by check or wire 
transfer, due within twenty (20) days after the date of each invoice; 
provided that Buyer may withhold payment of the portion of any invoice which 
is the subject of a bona fide dispute under the provisions of this Agreement. 
 Checks and wire transfers shall be made to Seller's account as follows:

percent per annum. All invoiced amounts shall be subject, however, to 
subsequent adjustment wherever this Agreement specifically so provides, and 
no interest shall be payable to either party with respect to the amounts of 
such adjustments.  If payment is not made when due, Seller may give Buyer 
written notice of such past due payment.  Three (3) days after such notice is 
effective, pursuant to Section 10.07, Seller may suspend deliveries until the 
invoice, including any interest, has been paid.  If the invoice is not paid 
within fifteen (15) days after Seller's notice becomes effective, Buyer's 
failure to make payment when due shall constitute a material breach of this 
Agreement by Buyer, and Seller may, at its sole option, cancel this 
Agreement.

         6.08      ADJUSTMENTS.  The parties recognize that at the time each 
invoice for coal is prepared, it may not be possible to calculate 
definitively the costs and other price

                                      19



adjustment factors applicable to the calendar half-month for which such 
invoice is rendered; each invoice will, therefore, be based upon the most 
current data reasonably available at the time of invoicing.  Upon receipt of 
information permitting determination of price adjustments, Seller shall 
prepare and furnish to Buyer a supplemental invoice reflecting that 
information.  Seller or Buyer shall, within fifteen (15) days after mailing 
of such supplemental invoice, pay the sum required by such invoice as above 
provided.

         6.09      FINALITY OF INVOICES.  Except as otherwise expressly 
provided in this Agreement, any invoice that is not contested within 
twenty-four (24) months after the date thereof shall be deemed correct and 
final unless any of the Pass-Through Costs have retrospective effect on the 
Purchase Price of coal more than 24 months after the date of invoice, and 
provided that Seller shall advise Buyer of any such effect or potential 
effect within a reasonable time following Seller becoming so aware.

         6.10      RECORDS AND AUDITS.  Seller shall keep accurate records 
and books of accounts showing all data relating to price, quantity and 
quality determinations and adjustments required for purposes of this 
agreement.  At the election of Buyer, once each fiscal year of Seller, Seller 
shall make such records and books of account covering the preceding fiscal 
year

                                      20


available for audit at Seller's offices during Seller's normal office hours.  
Such audits shall be prepared and certified to by a nationally recognized 
firm of certified public accountants to be mutually agreed by Buyer and 
Seller and Buyer shall bear the expenses of the audit.  The findings of the 
audit will be binding on the parties absent a finding by either party of a 
material error in the audit which error is identified within 60 days after 
completion of the audit and submission of the findings to the Seller.  If the 
audit discloses that an overpayment or an under payment has been made, the 
amount thereof shall promptly be paid to the party to whom it is owed by the 
other party.  Buyer shall have the option of having the audit prepared by 
Seller's independent auditors as part of the regular annual audit of Seller's 
books and records.  In such event, only those expenses in excess of Seller's 
normal audit expenses will be borne by Buyer.  The accounting firm conducting 
the audit shall be bound not to disclose and shall treat as confidential any 
and all proprietary information of Seller furnished to or examined by such 
firm in connection with the audit.


                         *CONFIDENTIAL TREATMENT  REQUESTED*

    SECTION 7.     DISCLAIMER OF WARRANTIES, LIMITATION ON LIABILITY.

         7.01      EXPRESS WARRANTIES.  BUYER AGREES THAT SELLER MAKES NO
EXPRESS WARRANTIES OTHER THAN THOSE IDENTIFIED AS SUCH IN THIS AGREEMENT.


                                          21



         7.02      IMPLIED WARRANTIES.  ALL WARRANTIES OF MERCHANTABILITY
OR OF FITNESS FOR A PARTICULAR PURPOSE OR ARISING FROM A COURSE OF DEALING OR
USAGE OF TRADE ARE SPECIFICALLY EXCLUDED.

         7.03      LIMITATION ON LIABILITY.  In no event shall either party have
liability to the other party for incidental or consequential damages except as
expressly stated in this Agreement.

    SECTION 8.     FORCE MAJEURE.

    If either party is unable to meet any of its obligation under this 
Agreement as a result of flood, earthquake, storm, or other act of God, fire, 
derailment, accident, strike, lockout, boycotts, picketing, shortages of or 
inability to obtain electric power, raw materials, railcars or machinery, 
mechanical breakdown in facilities, war, insurrection, riot, catastrophic 
sugar beet or corn crop failure (as applicable), railroad line abandonment, 
act of government or governmental agency, or due to any cause beyond the 
reasonable control of either party, including the inability of a Sugar 
Factory, the Mine and/or the rail carrier to meet its obligations for reasons 
whether similar or dissimilar to the foregoing and whether foreseeable or 
unforeseeable, such event will be deemed an event of force majeure.  In 
addition, it shall be deemed an event of force majeure in the event Buyer is

                                          22


unable to burn Seller's coal due to ash-fouling, sulfer dioxide emissions, or 
other legally enforceable environmental restrictions, or either party 
permanently closes or experiences partial failure or nonoperation of any of 
its facilities lasting a minimum of seven (7) days as a result of reasons 
beyond the control of such party.  In the event of force majeure, the 
obligations of the parties, other than payment for coal previously delivered, 
shall be suspended for the duration of the event of force majeure, provided 
that reasonable notice is given.  Whenever in Seller's judgment any event of 
force majeure requires restriction of deliveries, Seller reserves the right 
in its discretion to allocate its available supply of coal in a fair and 
equitable manner without obligation to furnish products from other sources.  
No suspension or reduction for reason of force majeure shall invalidate the 
remainder of this Agreement; but on removal of the cause, shipments shall 
resume at the specified rate; deficiencies in shipments so caused shall not 
be made up except by mutual consent.  If any event of force majeure prevents 
the performance of either party for a period of one year or more despite that 
party's efforts to eliminate the force majeure event and to mitigate its 
impact, then the party not claiming an event of force majeure may terminate 
this Agreement by providing at least thirty (30) days written notice of 
termination to the other

                                          23


party.  The provisions of this Section shall not excuse either party from
performing unless that party gives a reasonable notice to the other party of the
occurrence of an event of force majeure.

    SECTION 9.    DISPUTES.

    In the event any dispute arises between the parties concerning any issue of
law or fact arising out of this Agreement, it shall be settled by arbitration
pursuant to the Commercial Arbitration Rules of the American Arbitration
Association, and judgment upon the award may be entered in any court having
jurisdiction over the matter.

    The parties to the arbitration shall be entitled to such discovery as would
be available to them under the Federal Rules of Civil Procedure, and the
arbitrators will have all the authority of a court under such Rules incidental
to such discovery, including but not limited to orders to produce documents or
other materials and orders to appear and submit to deposition and to impose
appropriate sanctions, including but not limited to awarding sanctions against a
party for failure to comply with any order.

    The arbitration panel shall consist of three arbitrators with experience in
the coal industry, one appointed by Seller, one by Buyer and the third by the
arbitrators appointed by Seller


                                          24



and Buyer.  If the party appointed arbitrators cannot agree within fifteen (15)
days after their appointment on appointment of the third arbitrator, then the
third arbitrator shall be appointed by the American Arbitration Association.

    SECTION 10.    GENERAL PROVISIONS.

         10.01     WAIVER.  Failure of either party at any time to require
performance of any provision of this Agreement shall not limit that party's
right to enforce the provisions, nor shall any waiver of any breach of any
provision be a waiver of any succeeding breach of the provision itself or of any
other provision.
