        NOW THEREFORE, in consideration of the premises and the mutual
covenants and agreements of the parties hereinafter set forth, it is hereby
agreed by and between the parties hereto as follows:


SECTION 1.  TERM.

(a)     The term of this Agreement shall commence as of the first date written
        above and shall continue in effect through December 31, 2000.

(b)     Buyer has sole option to extend the term of this Agreement for any
        period up to five (5) years subject to reserve tonnage verification
        and price negotiation.  Buyer shall notify Seller of the exercise of
        such option on or before August 25, 1999.  Should Buyer and Seller not
        mutually agree upon price by December 31, 1999, Seller shall not sell
        coal, to another buyer, at a price lower than quoted by Seller to
        Buyer.  Such restriction on Seller shall be effective until December
        31, 2001.

SECTION 2.  QUANTITY.

(a)     The quantity of coal to be sold and purchased under this Agreement
        shall be 300,000 tons per Contract Year of Coal having a sulphur
        dioxide content not to exceed 2.0 pounds per million British Thermal
        Units (MMBTU), as described in Section 4(a) and 4(b), and an 
        additional 250,000 tons per Contract Year of coal having a sulphur 
        dioxide content not to exceed 2.4 pounds per MMBTU, as described in 
        Section 4(a) and 4(b), for a total of 550,000 tons per contract year.  
        "Ton" shall be defined as a short ton of 2,000 pounds avoirdupois 
        weight. "Contract Year" shall be defined as a period beginning on 
        January 1 and ending on the succeeding December 31.  If the first year 
        is a partial Contract Year, the quantities will be prorated coincident 
        with the number of days available for shipment from the date of
        commencement of shipments through the end of the calendar year.

(b)     On or before November 1 of each Contract Year, Buyer shall retain the
        right, upon written notice to Seller, to increase or decrease either,
        or both, of the two different quantities in Section 2(a) above for the
        next Cotnract Year by an amount not greater than 10%.

(c)     Buyer shall have the right of first refusal regarding Spot Sales from
        all reserves in the State of Indiana owned or controlled by Seller
        presently or in the future.  "Spot Sales" shall be defined as tonnage
        sold under a contract term of one year or less, or tonnage sold under
        a contract term of one year or less and subsequently extended by one
        year increments.  To exercise this right, Buyer must respond to Seller
        by accepting or rejecting a bona fide offer within twenty-four (24)
        hours after receipt of notice from Seller regarding another proposed
        sale.  Notice to Buyer shall include all terms and conditions of the
        sale such as, but not limited tok, source, quality, quantity by month
        and term, F.O.B. mine and delivered prices, means of delivery, F.O.B.
        point, and premium or penalty provisions.  Such notice shall
        constitute an offer to sell to Buyer under the terms thereby defined. 
        If Buyer refuses such offer, then Seller may sell that coal, to said
        buyer only, under terms and conditions of that agreement shall remain
        identical to the notice presented to Buyer throughout the life of that
        agreement.  So long as Seller complies in good faith with these
        provisions, the provisions of Subsection 6(q) shall not apply.


SECTION 3.  SOURCE OF COAL AND DELIVERIES.

(a)     The source of coal shall be the reserves of Seller located in Greene
        County, Indiana, identified on Exhibit A and nearby reserves which may
        be acquired by Seller. Exhibit A will be updated as Seller acquires
        additional reserves for this Agreement.  Seller covenants that it will
        not sell or contract to sell coal from said reserves in such manner
        or quantity as to jeopardize its ability to perform under the terms
        of this Agreement.  Seller further covenants that coal from sources
        not previously approved by Buyer in writing will not be included in
        shipments to Buyer.

(b)     Coal subject to this Agreement shall be delivered by Seller to Buyer
        FOB trucks (to be arranged by Buyer) loaded at Seller's mine, or at
        Buyer's option, FOB railcars (to be arranged by Buyer) at Seller's
        rail siding (the location of which is set forth in Exhibit A). 
        Seller's rail siding(s) shall have the capacity to hold and load a
        minimum of fifty-five 100-ton capacity railroad cars in accordance
        with existing tariff or applicable rail contract or both.  "Shipment"
        shall be defined as a single train rail delivery or, if trucks are
        used for transporting the coal, "Shipment" shall be defined as the sum
        of one day's truck deliveries from any one of Seller's loading points
        to any one of Buyer's Stations.  Risk of loss shall follow title to
        the coal.  Title shall pass when coal is delivered to trucks or
        railcards by Seller.  Point of delivery for purposes of Sections 5 and
        6 of this Agreement shall be FOB railcar or truck as the case may be. 
        Point of delivery for Purposes of Sections 4, 7 and 9 of this
        Agreement shall be FOB Buyer's Station(s).

(c)     Coal deliveries subject to this Agreement shall be made in
        substantially equal monthly quantities subject to the vacation and
        holiday schedules of Seller, Buyer and shippers and in accordance with
        Buyer's shipping instructions.

(d)     The primary destination of coal deliveries shall be Buyer's H.T.
        Pritchard Station and C.C. Perry K Station.  Buyer shall have the
        right, but not the obligation, to direct shipments to any other of its
        Stations.

       deliveries of any and all coal subject to this Agreement until
       Seller gives assurances acceptable to Buyer that it has corrected
       such deviations.  If 1) such assurances are not given within thirty
       (30) days following such suspension, and 2) Seller uses its best
       efforts to meet the quality specifications and is unable to do so,
       then Buyer's remedies shall be limited to terminating this

       railcars.

(e)    Seller warrants that coal delivered to Buyer shall not contain
       extraneous materials that would render the coal, in Buyer's sole
       opinion, unsuitable for use at Buyer's Station(s).  Extraneous
       materials include, but are not limited to, slate, shale, fireclay,
       rock, stone, dirt, mud, wood and rags.  Should any Shipment(s) of
       coal containing such extraneous material be delivered to any of
       Buyer's Stations then Buyer may immediately reject such Shipment(s)
       and title to such Shipment(s) shall revert to Supplier.


(f)    THE QUALITY SPECIFICATIONS SET FORTH IN THIS SECTION 4 SHALL BE IN
       LIEU OF ANY OTHER WARRANTY OF QUALITY, EXPRESS OR IMPLIED,
       INCLUDING BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF
       MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

(g)    For purposes of this Agreement pounds of sulfur dioxide per million
       BTU shall be calculated according to the following:


            Pounds of SO2 per MMBTU =

            (%S X 20,000)/(As-received BTU/pound)


       Percent sulfur and As-received BTU per pound shall be determined in
       accordance with Section 9.

SECTION 8.  WEIGHTS.

(a)    The weight of coal shipped shall be determined on scales maintained
       by Seller.  The weights thus determined shall be accepted as the
       quantity of coal for which invoices are to be rendered and payments
       made in accordance with Section 10.  Seller shall arrange for such
       scales to be properly inspected and approved at least twice each
       year by either the railroad, a mutually acceptable representative
       agency, or the scale manufacturer in accordance with the applicable
       standards established by the carrier or the appropriate weighing
       and inspection bureau, and subject to verification by Buyer and all
       carriers involved in the delivery to Buyer's Station(s).  Seller
       shall notify Buyer in advance of all scale inspections, and Buyer
       shall have the right to have a representative present.

(b)    Buyer shall have the right to have a representative present at any
       and all times to observe the weighing of the coal.  If Buyer should
       at any time question the accuracy of the scales, Buyer shall so
       advise Seller, who shall arrange for the scales to be tested,
       subject to Buyer's rights detailed in Subsection 8(a).  Such tests
       shall be conducted by the railroad, the Indiana State Bureau of
       Weights and Measures, a mutually acceptable representative agency
       or the scale manufacturer.  Tests shall be performed in accordance
       with the applicable standards established by the carrier or the
       appropriate weighing and inspection bureau.  If such tests show
       Seller's scales to be in error, said scales shall be adjusted to an
       accurate condition.  If any such inspection or test reveals an
       error in weight in excess of one-half percent (1/2%), then weights
       of the coal measured on that scale during the period commencing
       with the date on which the accuracy was questioned to the date that
       scale is correctly calibrated shall be adjusted in proportion to
       the calibration error.  Invoices submitted during this period shall
       be adjusted in accordance with said adjustment to weights.  No
       adjustments shall be made to invoices submitted prior to the time
       the accuracy of the scales was questioned.

(c)    Buyer retains the option to weigh coal deliveries on Buyer's scales
       at any time and for any reason from time to time.  If Buyer chooses
       to exercise this option, then Buyer will notify Seller in writing
       and the rights and responsibilities of Seller per Subsections 8(a)
       and 8(b) shall be assumed by Buyer, and the rights and
       responsibilities of Buyer thereunder shall be assumed by Seller.


SECTION 9.  SAMPLING AND ANALYSIS.

(a)    Each day that coal is delivered hereunder, Buyer shall take or
       cause to be taken representative samples of such coal.  Buyer shall
       further cause to be determined by proper analysis the quality and
       characteristics of the coal.  Sampling shall consist of
       representative samples, manually gathered, from at least 20% of the
       railcars or trucks in each Shipment or by mechanical sampling
       systems where available.  Analysis of each Shipment shall be
       performed in general accordance with ASTM procedures.  Buyer shall
       furnish semi-monthly to Marine and Triad a report showing the
       quality of the coal on a Shipment basis.  Seller shall have the
       right to have a representative present at any and all times to
       observe the sampling and analysis.  Results of sampling and
       analysis by Buyer shall determine the quality of each Shipment.

(b)    If Seller should at any time question either Buyer's sampling
       methods or the results of any of Buyer's analyses, Seller shall
       have the right, at its expense, to have the coal sampled at
       destination and analyzed by a commercial testing laboratory, which
       will be chosen mutually by the Parties.  Tests shall be performed
       using standards developed by ASTM, Bureau of Mines, or other
       mutually acceptable procedures.  The results of such sampling and
       analysis shall be accepted as the quality of the coal for each
       Shipment so sampled.

(c)    If Buyer's sample is from less than 20% of a Shipment, the results
       of Seller's sample and analysis shall determine the quality and
       characteristics of such Shipment.

(d)    Buyer has the right to require sampling and analysis on a more
       frequent basis and as necessary in order to assure compliance with
       applicable environmental standards.  In such event, the term
       "Shipment" in Subsection 3(b) shall be redefined by Buyer to the
       extent required to assure such compliance.


SECTION 10.  BILLING AND PAYMENT.

(a)    As provided in the Sales Service Agreement, Marine shall be
       responsible for the rendering of invoices to Buyer.  After the 15th
       day of each month, Marine shall render an invoice to Buyer covering
       the coal shipped during the first fifteen (15) days of that month. 
       After the last day of each month, Marine shall render an invoice to
       Buyer covering the coal shipped during the sixteenth day through
       the last day of that month.  Buyer shall, within ten (10) business
       days after receipt of each invoice, pay to Seller's account at
       National City Bank of Louisville, by cash or check, in United
       States funds, the net amount of that invoice.  Each invoice shall
       be for the Adjusted Base Price approved by Buyer, in effect at the
       time of shipment.

(b)    As soon as practical after all pertinent data has been received
       relating to quality, Buyer shall issue to Marine a debit or credit
       memo giving effect to all adjustments for the month's shipments
       relative to quality as detailed in Section 7.  If additional
       amounts are due from Buyer, Buyer shall pay to Seller's account at
       National City Bank of Louisville, by cash or check, in United
       States funds, the net amount of each invoice within ten (10)
       business days after receipt.  If credits are due, Buyer shall
       deduct the amount of any credit memo from the next payment due.

(c)    Payment shall be deemed to have been made on the date that any
       check is deposited in the United States Mail.


SECTION 11.  RECORDS AND AUDITS.

(a)    Seller and Marine shall keep accurate and satisfactory records and
       books of account showing all financial and technical data required
       for purposes of administering this Agreement.

(b)    Each time the Base Price is adjusted in accordance with any
       provision of Section 6, Marine shall furnish to Buyer a detailed
       statement showing the calculations of the Adjusted Base Price and
       the basis for the proposed adjustment.

(c)    Buyer shall have the right at all times and at any time, upon
       reasonable and written notice, to examine or to cause a nationally
       recognized accounting firm or mining engineering firm to examine
       the reserves, mine, and records of Seller and Marine as they
       pertain to this Agreement.  The cost of such examination shall be
       borne by Buyer.



SECTION 12.  FORCE MAJEURE.

(a)    The term "force majeure" shall mean any and all causes beyond the
       control and without the fault or negligence of the Party failing to
       perform.  Such causes shall include but not be limited to acts of
       God, acts of the public enemy, insurrections, riots, labor
       disputes, boycotts, labor and material shortages, fires,
       explosions, floods, breakdowns of or damage to equipment or
       facilities, interruptions to transportation, embargoes, acts of
       military authorities, or other causes of a similar nature whether
       or not foreseen or foreseeable which wholly or partly prevent the
       mining, loading and/or delivery of the coal by Seller; or the
       receiving, unloading, accepting, and/or utilizing of the coal by
       Buyer.  Settlement of labor disputes shall be deemed beyond the
       control and without the fault or negligence of the Party
       experiencing such event.  Documentation verifying a condition of
       force majeure shall be made available by the Party invoking the
       provisions of this Section.

(b)    If, because of a verifiable condition of force majeure, either
       Party is unable to carry out any of its obligations under this
       Agreement (except for obligation of either Party to pay money in
       connection with the performance of this Agreement), that Party
       shall promptly give written notice to the other Party.  The
       obligation of the Party giving notice shall be suspended to the
       extent made necessary by said force majeure during its continuance. 
       However, the Party giving notice shall use commercially reasonable
       efforts to eliminate the force majeure with a minimum of delay. 
       Any deficiencies in deliveries of the coal caused by a condition of
       force majeure shall not be made up except by mutual consent.

(c)    During a period in which Buyer invokes a condition of force
       majeure, Seller, in the absence of mutual agreement to make up
       deficient deliveries, may sell to others the coal otherwise
       designated for Buyer.  Likewise, during a period in which Seller
       invokes a condition of force majeure, Buyer, in the absence of
       mutual agreement to make up deficient deliveries, may buy from
       others the coal otherwise to have been purchased from Seller.


SECTION 13.  COMPLIANCE WITH ANTI-POLLUTION LAWS AND
             REGULATIONS, ETC.

(a)    The Parties to this Agreement recognize that, during the term of
       this Agreement, legislative bodies, regulatory agencies or courts
       having competent jurisdiction over the subject matter of this
       Agreement may enact laws or 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 Buyer to utilize
       the coal subject to this Agreement at H.T. Pritchard Station for
       the 2.4 pounds of sulphur dioxide per mmBTU product, or C.C. Perry
       K Station for the 2.0 pounds of sulphur dioxide per mmBTU product
       without changing or altering its present equipment.  Such laws,
       regulations or orders may pertain to, but would not necessarily be
       limited to, the sulfur content of the coal.  If any such laws,
       regulations or orders are imposed, Buyer shall provide written
