      WHEREAS, the parties wish to further amend the Agreement, and to settle
certain disputes between the parties;

      WHEREAS, Buyer and Sellers are of the opinion that it would be mutually
beneficial to combine the original Agreement and all amendments into one
document for clarity and ease of administration; and

      WHEREAS, Sellers agree to sell and Buyer agrees to purchase coal upon
terms and conditions as follows:

      NOW, THEREFORE, in consideration of the mutual benefits to be derived, as
of July 1, 1996, Buyer and Sellers do hereby amend and combine the original
Agreement and all amendments into this document.

      1.0   Description. The description of the coal to be sold and delivered
            under this Agreement for use at Buyer's Roxboro 4 and/or Mayo 1
            Units is made part of the basis of the bargain of the Agreement.
            Conformity to the description also requires that the coal be
            substantially free from impurities. The said coal shall not be
            larger than 2 inches in diameter, but may be of smaller size
            provided such smaller size does not cause Buyer unusual difficulties
            in handling and utilization. The said coal shall conform to the
            following quality characteristics:

                  Buyer and Sellers understand and agree that the tonnages set
                  forth above are annual commitments and that Buyer and Sellers
                  shall schedule, ship and accept shipments each calendar month
                  as necessary to insure that such annual contract commitments
                  are satisfied each calendar year, subject to the provisions of
                  Paragraph 8.0, Force Majeure. Monthly shipping schedules will,
                  where possible, be adjusted to reflect Sellers' planned
                  vacation period and Buyer's planned maintenance outages.

                  (1)   On or prior to December 1 of each calendar year during
                        the term hereof, Sellers shall provide Buyer with a
                        tentative schedule of monthly coal shipments during the
                        ensuing calendar year. Buyer shall promptly review this
                        schedule and notify Sellers of any modifications within
                        ten (10) business days of receipt. Buyer and Sellers
                        shall then agree on the tentative monthly shipping
                        schedule for the ensuing calendar year on or prior to
                        December 20.

                  (2)   Buyer shall specify to Sellers on or prior to the
                        twenty-fifth day of each calendar month during the term
                        hereof the dates and destinations for shipments to be
                        made hereunder in the next succeeding calendar month;
                        provided, however, that Buyer reserves the right to
                        change the destination of such shipments at any time.

            (b)   The term "ton" as used herein shall mean a net ton of two
                  thousand pounds, avoirdupois weight.

            (c)   Sellers will load coal sold hereunder pursuant to trainload or
                  other applicable tariffs (and supplements) established by the
                  railroad that will haul the coal, and such other tariffs as
                  may evolve that are mutually acceptable to Buyer, Sellers, and
                  the railroad. Loading of trains at the rate of at least 10,000
                  tons in a 4-hour period will be performed by Sellers,
                  exclusive of holidays, in accordance with the provisions of
                  applicable freight tariffs.

            (d)   Buyer and Sellers shall mutually arrange for the necessary
                  rail cars to make the specified deliveries and Sellers shall
                  cause the coal to be loaded in a manner that will assure
                  reasonably uniform consistency as to size and quality. Sellers
                  shall cause each rail car to be loaded to full visible
                  capacity, and shall reimburse Buyer for any penalty and
                  freight charges resulting from deficits in carload minimum
                  weight. Sellers shall pay any costs of demurrage or storage at
                  the shipping points not caused by Buyer.

            (e)   The coal shipped hereunder shall be supplied from the loadout
                  facilities of Marrowbone or, at Sellers' sole discretion, any
                  other source, provided that:

                                       3
<PAGE>

                  (1)   With respect to shipments from Marrowbone, Sellers shall
                        have the right, at their sole discretion, to purchase
                        and/or process coals produced by other coal producers
                        (whether affiliated with Sellers or not) and to ship
                        such coal to Buyer, provided that the coal shipped to
                        Buyer satisfies the quality characteristics specified in
                        Paragraph 1.0, Description.

                  (2)   The f.o.b. mine prices set forth in Paragraph 5.0, Price
                        are based on shipment from the Marrowbone loadout
                        facility at Naugatuck, West Virginia. In the event
                        Sellers elect to ship coal from any origin other than
                        the Marrowbone loadout at Naugatuck, West Virginia, the
                        f.o.b. mine place for such shipments shall be adjusted
                        to result in the same delivered cost to Buyer,
                        calculated in cents per million Btu, as the cost which
                        would have resulted if such shipments had originated
                        from Marrowbone.

                  (3)   With the exception of purchases of replacement coal for
                        non-shipment arising out of force majeure events (as
                        provided in Paragraph 8.0, Force Majeure), if Sellers
                        elect to supply coal to Buyer from sources other than
                        Marrowbone, such coal shall be purchased by Sellers
                        under a contract with a coal producer with a term of at
                        least sixty (60) days. Sellers shall notify Buyer before
                        shipping any coal to Buyer from a source or seam other
                        than those from which coal has been shipped to Buyer in
                        the past hereunder.

      2.1   Weights.

            (a)   In the event that coal is delivered from the Marrowbone
                  loadout at Naugatuck, West Virginia, Sellers will determine
                  the weight of coal delivered under this Agreement by means of
                  electronic belt scales located at the mine site, provided and
                  operated by Sellers and approved by the railroad. The loaded
                  weight will be determined for each train for each loading and
                  such weight shall be the basis for payment by Buyers. Sellers
                  shall test and calibrate such scales at thirty (30) day
                  intervals to maintain them at a trainload accuracy within plus
                  or minus 0.5 percent through the use of calibration techniques
                  acceptable to Sellers, Buyer, and the railroad. Testing,
                  calibration, and certification of the scales will be under the
                  jurisdiction of the railroad and the applicable state agency.
                  Sellers shall promptly provide Buyer with a copy of the
                  results of all scale testing, calibrations, and
                  certifications.

            (b)   Sellers shall give immediate notice by telephone or facsimile,
                  and confirm such notice in writing to both Buyer and the
                  railroad, if and when Sellers discover that the weighing
                  facilities have become inoperable or are discovered to be in
                  error beyond the limits mentioned above. During any period
                  when such weighing facilities are inoperable or in error,

                                       4
<PAGE>

                  determination of the quantities of coal delivered shall be
                  made by a procedure to be established by Buyer, Sellers, and
                  the railroad.

            (c)   Buyer shall have the right to have a representative present at
                  any and all times to observe the determination of weights. If
                  Buyer should at any time question the accuracy of the weights
                  thus determined, Buyer shall so advise Sellers, and confirm
                  such advice in writing, and Sellers shall arrange to test the
                  weighing devices or methods. If such tests show the weighing
                  devices to be in error, they shall be adjusted to the required
                  accuracy as mutually agreed upon by Buyer and Sellers, in
                  accordance with generally accepted calibration techniques used
                  in the coal and railroad industries.

            (d)   If the weighing devices are determined to be in error beyond
                  the limits as set forth in Paragraph 2.1(a), an appropriate
                  adjustment shall be made in weights and related payments;
                  provided, however, that no such adjustment shall be
                  retroactive for a period in excess of thirty (30) days prior
                  to the date that Buyer first questioned Sellers about the
                  accuracy of the weighing devices or methods, or thirty (30)
                  days prior to the discovery of the inaccuracy of the weighing
                  devices if the inaccuracy is discovered upon a regularly
                  scheduled testing.

            (e)   In the event Sellers elect to supply coal to Buyer from
                  sources other than Marrowbone, the weight of coal in each
                  shipment shall be determined in accordance with Buyer's
                  transportation contract with the railroad, any amendments
                  thereto, or any new agreements between Buyer and the railroad
                  for the transportation of coal hereunder. Sellers shall have
                  the right, but not the obligation, to weigh such coal at
                  Seller's loading facilities as long as such weights are
                  determined by scales and in accordance with policies and
                  procedures approved by the railroad. Sellers shall reimburse
                  Buyer for any and all costs associated with the weighing of
                  such coal charged by the railroad to Buyer. Weights so
                  determined shall be accepted by the parties for purposes of
                  payment hereunder

      3.0   Term of Agreement. The term of this Agreement shall be for the
            period beginning October 1, 1976 and ending December 31, 2006.

      4.0   Payment. Buyer shall make payments in accordance with the following
            schedule:

            (a)   For coal received at Buyer's plants from the first day of the
                  month through the fifteenth day of the month, payment will be
                  made on or before the tenth day of the following month.

            (b)   For coal received at Buyer's plants from the sixteenth day of
                  the month through the last day of the month, payment will be
                  made on or before the twenty-fifth day of the following month.

      5.2   Buyer and Sellers recognize that the prices set forth in Paragraph
            5.1 may require adjustment, either increase or decrease, because of
            the imposition of federal or state legislation or regulation after
            July 1, 1996, or any changes in the interpretation and enforcement
            of existing federal or state requirements after

                                       6
<PAGE>

            July 1, 1996, that impose or change a tax, assessment or other
            governmental charge based on the volume of tons produced or the
            price of coal sold by Sellers under this Agreement. In the event of
            such an imposition, either party may submit to the other party
            detailed documentation of the proposed price adjustment, and Sellers
            and Buyer shall meet to discuss and attempt to agree upon an
            adjustment to reflect the actual change in Sellers' costs.

            In the event that Sellers elect to supply coal from sources other
            than Marrowbone, the provisions of this Paragraph 5.2 shall only
            apply to the price of coal from such sources if (i) Sellers purchase
            such coal for resale to Buyer under a contract with a term of at
            least one (1) year, and (ii) the contract between Sellers and the
            supplier of such coal provides for the payment by Sellers to the
            supplier of the types of costs described in this Paragraph 5.2,
            including any such costs in effect at the time Sellers execute a
            contract for the purchase of coal from such sources.

            In the event that Sellers elect to blend coal subject to price
            adjustments pursuant to this Paragraph 5.2 with other coals, only
            the price for the percentage of such coal supplied to Sellers that
            is subject to this Paragraph 5.2 shall be adjusted.

            In the event Sellers and Buyer are unable to agree as to the amount
            the price per ton should be increased or decreased, then the matter
            shall be submitted to an independent third party experienced in the
            matters in question that is acceptable to both Sellers and Buyer.
            The cost of such third party shall be borne equally by Buyer and
            Sellers. The price increase or decrease per ton, as determined by
            the independent third party, shall be binding on both Sellers and
            Buyer; provided, however, that any increase shall not exceed the
            amount previously proposed by Sellers, and any decrease shall not
            exceed the amount previously proposed by Buyer. In the event a third
            party cannot be agreed upon, the provisions of Paragraph 18.0, Third
            Party Selection shall apply.

      5.3   On the day of execution of this Agreement, Buyer shall remit a
            payment for coal of $3,013,000 to Sellers.

            Buyer shall remit the following additional payments for coal to
            Sellers on or before the dates specified:

      6.0   Remedies for Quality Deviations. The following are Buyer's sole and
            exclusive remedies for coal quality deviations from the quality
            characteristics specified in Paragraph 1.0, Description:

            (a)   A price adjustment shall be applied to Sellers' account when
                  there is a difference between the as-received Btu per pound
                  and 12,000 Btu per pound. If and when the results of analysis
                  reflect that the average Btu content of coal delivered
                  hereunder, calculated on a per purchase order basis, is less
                  than 11,900 or more than 12,100 Btu per pound, a price
                  adjustment will be made based upon the delivered cost of coal
                  to Buyer, including the actual freight rate per ton, excluding
                  the payment for coal pursuant to Paragraph 5.3.

                                     EXAMPLE

            For coal delivered with a weighted average quality of 12,200 Btu per
            pound on a purchase order basis at a price per ton of $19.20 and a
            freight rate of $4.31 per ton, an increase in the price per ton
            would be calculated as follows:


                         
Price                       $19.20
Freight Rate                  4.3l
                            ------
Delivered Cost/Ton          $23.51

200 Btu/lb. Variance        X $23.51 = $.3918/ton increase in the price per ton
------------------------
12,000 Btu/lb. Guarantee


            For coal delivered with a weighted average quality of 11,800 Btu per
            pound on a purchase order basis at a price per ton of $19.20 and a
            freight rate of $4.31 per ton, a decrease in the price per ton would
            be calculated as follows:


                         
Price                       $19.20
Freight Rate                  4.3l
                            ------
Delivered Cost/Ton          $23.51

200 Btu/lb. Variance        X $23.51 = $.3918/ton decrease in the price per ton
------------------------
12,000 Btu/lb. Guarantee


            (b)   Moisture Content

                  (1)   If the weighted average moisture content calculated on a
                        per purchase order basis exceeds 8.5%, a price
                        adjustment of $.20 per ton per percentage point
                        (fractions pro rata) will be credited to Buyer for all
                        tons shipped under that purchase order.

                  (2)   If the moisture content of any trainload shipment of
                        coal exceeds 9.0%, a price adjustment of $.25 per ton
                        will be credited to Buyer for all tons in such trainload
                        shipment.

                                       8
<PAGE>

            (c)   Ash Content

                  (1)   If the weighted average ash content calculated on a per
                        purchase order basis exceeds 13.2%, a price adjustment
                        of $.30 per ton per percentage point (fractions pro
                        rata) will be credited to Buyer for all tons shipped
                        under that purchase order.

                  (2)   If the ash content of any trainload shipment of coal
                        exceeds 14%, a price adjustment of $.40 per ton will be
                        credited to Buyer for all tons in such trainload
                        shipment.

            (d)   Grindability (HGI)

                  (1)   If the weighted average grindability calculated on a per
                        purchase order basis is less than 39, a price adjustment
                        of $.25 per ton per grind point (fractions pro rata)
                        will be credited to Buyer for all tons shipped under
                        that purchase order.

                  (2)   If the grindability of any trainload shipment of coal is
                        less than 38, a price adjustment of $.35 per ton will be
                        credited to Buyer for all tons in such trainload
                        shipment.

            (e)   Sellers agree to promptly supply Buyer with an analysis,
                  performed in accordance with ASTM standards, of the sulfur
                  content of each shipment of coal supplied under this
                  Agreement. In the event that the sulfur content of any single
                  trainload shipment exceeds 1.2 lbs. SO(2)/mmBtu, Buyer shall
                  have the right to reject such trainload shipment, and title
                  and risk of loss shall revert back to Sellers upon rejection.
                  In the event that a trainload shipment of coal is rejected by
                  Buyer, Sellers shall reimburse Buyer for its actual costs
                  incurred including transportation from the mine to
                  destination. Buyer shall not unload any trainload shipment
                  delivered hereunder until it has received Sellers' analysis
                  reflecting a sulfur content of 1.2 pounds SO(2)/mmBtu or less.
                  Sellers agree to reimburse Buyer for any demurrage incurred as
                  a result of holding any trainload shipment while awaiting
                  receipt of such analysis.

            (f)   In the event that Sellers are supplying coal hereunder from a
                  source other than Marrowbone mines producing coal in the
                  Coalburg, Clarion and/or 5-Block seams and the analysis of any
                  trainload shipment containing any coal from such source
                  indicates an Ash Fusion Temperature (H=W, Reducing) less than
                  2400(degree)F or a Volatile Matter content of less than 25.0%
                  (30% effective January 1, 2000), Buyer may suspend further
                  shipments from such source until Sellers give Buyer reasonable
                  assurances that further shipments from such source will
                  satisfy the requirements of Paragraph 1.0, Description. For
                  the purpose of this Paragraph 6.0(f), a source shall be
                  defined as an individual mine or a readily identifiable seam
                  for which quality is ascertainable, and from which coal is
                  produced for

                                       9
<PAGE>

                  delivery hereunder. Any trainload shipments containing any
                  coal from such source that have an Ash Fusion Temperature
                  (H=W, Reducing) less than 2400(degree)F or a Volatile Matter
                  content of less than 25.0% (30% effective January l, 2000)
                  that have not yet been unloaded may be rejected by Buyer, and
                  upon rejection, Sellers shall reimburse Buyer for its actual
                  costs incurred including transportation from the mine to
                  destination, and title and risk of loss shall revert to
                  Sellers.

                  In the event that shipments hereunder originate at any
                  Marrowbone mine producing coal in the Coalburg, Clarion,
                  and/or 5-Block seams, Buyer shall not have the right to
                  suspend or reject shipments based on the Ash Fusion
                  Temperature or Volatile Matter content of such shipments.

      6.1   Other Quality Parameters. In the event Buyer is unable, after
            exerting reasonable efforts, to burn coal shipped hereunder from
            reserves other than the Coalburg, Clarion and/or 5-Block seam
            reserves controlled by Marrowbone as of July 1, 1996 because such
            coal causes significant operating problems that are directly
            attributable to a quality parameter other than those set forth in
            Paragraph 1.0, Description, Buyer shall consult with Sellers, and
            allow Sellers' combustion consultants reasonable access to Buyer's
            records, facilities, and personnel, in an effort to alleviate such
            problems. In the event the parties' efforts do not alleviate such
            operating problems within forty-five (45) days from Buyer's
            notification to Sellers of the problem, Sellers shall, at their sole
            discretion, elect either (i) to change to a source that Sellers,
            after reasonable consultation with Buyer, determine will alleviate
            such operating problems, in which case shipments will commence as
            soon as practicable from such changed source and any shipments
            missed as a result of Buyer's operating problems or the change in
            source shall be made up as soon as practicable, or (ii) to cease
            shipments hereunder for the remaining term of the contract or
            commitment for the source that Sellers and Buyer believe is causing
            such operating problems. Buyer's operating problems, and Sellers'
            election of either of the foregoing options, shall not excuse or
            otherwise effect Buyer's obligation to make payments for coal
            pursuant to Paragraph 5.3.

            Upon request by Sellers, Buyer shall evaluate any source or seam of
            coal to be supplied under this Agreement, and if such source or seam
            is approved by Buyer, in writing, in advance of the commencement of
            shipments from such source or seam, the provisions of this Paragraph
            6.1 shall not apply. Such approval shall not be unreasonably
            withheld, and Buyer shall not withhold such approval if it has
            previously purchased coal from the source or seam in question and
            burned such coal without encountering significant operating
            problems. Sellers shall provide Buyer with quality information
            regarding the seam or source. In the event Buyer has not burned coal
            from the source or seam in question, Buyer may test burn such coal.
            If Sellers request a test, Buyer shall test burn such coal unless
            the quality information provided to Buyer indicates that there is a
            quality characteristic inherent in the coal, other than those
            specified in Paragraph 1.0, Description, which prevents the burning
            of such coal at Roxboro 4 and/or Mayo 1

                                       10
<PAGE>

            Units. The coal supplied for such test will be supplied at a
            mutually agreed-upon price, consistent with the spot market price
            for compliance coal at the time of the shipment. The quantity of
            coal supplied for the test burn shall not exceed 50,000 tons, and
            such quantity will be in addition to the tonnage commitment pursuant
            to Paragraph 2.0, Quantity and Delivery. Buyer shall inform Sellers
            of its decision to approve or disapprove such source or seam within
            ten (10) days of receipt of all necessary information and/or
            completion of any test burn of the coal.

      7.0   Sampling and Analysis. Sellers or their designee shall sample and
            analyze each trainload shipment of coal to be delivered to Buyer to
            determine the quality parameters specified in Paragraph 1.0,
            Description. Such sampling and analysis shall be performed in
            accordance with ASTM standards or by other mutually acceptable
            methods. Sampling of the coal will be performed as the coal is
            loaded into railcars. Sellers or their designee shall provide
            trainload analyses to Buyer as soon as practicable after each train
            is loaded.

      7.1   Buyer or its representative shall have the right to inspect the
            sampling system(s) and laboratory used to sample and analyze the
            coal applied hereunder at any and all times that coal is loaded or
            analyzed for delivery to Buyer. Should it be determined that the
            sampling system(s) or laboratory are not in compliance with ASTM
            standards for sampling and analyzing coal, Sellers agree to take the
            necessary steps to ensure that future shipments of coal to Buyer are
            sampled and analyzed in accordance with ASTM standards. Prior to or
            within ten (10) days of the first shipment of coal that is sampled
            or analyzed by a sampling system or laboratory that has not
            previously sampled or analyzed deliveries under this Agreement,
            Sellers shall provide Buyer with independent confirmation that the
            sampling system and/or the laboratory are in accordance with ASTM
            standards.

      7.2   Should it be determined that sampling or analysis of a trainload
            shipment was not performed by Sellers or their designee in
            accordance with ASTM standards, the parties agree that (i) Buyer's
            sampling and analysis shall govern for that shipment or (ii) if
            neither party performed the sampling and analysis of that shipment
            in accordance with ASTM standards, the shipment shall be deemed not
            to have been sampled and analyzed for the purposes of this
            Agreement. The sampling and analysis of a shipment that was
            performed in accordance with ASTM standards and that was used in
            calculating adjustments to monthly billings in accordance with
            Paragraph 6.0, Remedies for Quality Deviations herein shall govern
            for all other purposes under this Agreement.

      7.3   As soon as practicable after the end of each month, the weighted
            average quality of the coal delivered hereunder for the quality
            parameters specified in Paragraph 1.0, Description hereof during
            that month shall be determined on a purchase order basis and
            provided to Buyer. The quality results thus determined shall be used
            in calculating price adjustments pursuant to Paragraph 6.0, Remedies
            for Quality Deviations.

                                       11

      7.4   In the event that Sellers elect to ship coal from source(s) other
            than Marrowbone pursuant to Paragraph 2.0(e) that will deliver coal
            directly to Buyer under a purchase agreement with a term of one year
            or more, or volume of 500,000 tons or more, Buyer shall promptly
            review the independent confirmation that the sampling system is in
            accordance with ASTM standards pursuant to Paragraph 7.1. If the
            subject sampling system has been changed since its last bias test,
            or has not been bias tested within the last eighteen (18) months,
            and Buyer has reasonable concerns regarding possible bias of such
            system, Buyer shall have the right to request a bias test of the
            sampling system, to be conducted within sixty (60) days of
            commencement of shipments from such source, by an independent third
            party in conformance with the Rose method for bias testing. A report
            of the test will be supplied to Buyer and Sellers. Should the
            results of the bias test show a "statistically significant bias" in
            the sampling system as determined by the third party, Sellers shall
            take immediate action to eliminate such bias, and shall pay for all
            costs of the bias test. If the bias test does not show a
            "statistically significant bias" in the sampling system, Buyer shall
            pay for all reasonable costs of the bias test. In the event the
            third party called for above cannot be agreed upon, the provisions
            of Paragraph 18.0, Third Party Selection shall apply.

      8.0   Force Majeure

      8.1   Neither party shall be subject to liability to the other for failure
            to perform in strict compliance with this Agreement where such
            failure results from an event or occurrence beyond the control of
            the party affected thereby such as, without limitation, acts of God,
            war, insurrection, riots, strikes, labor disputes, labor and
            material shortages, fires, explosions, floods, breakdowns or damage
            to the mines, plants, equipment or facilities, interruptions to
            transportation, car shortages, embargoes, orders or acts of civil or
            military authority, legislation, regulation, or administrative
            ruling. Normally scheduled maintenance outages, including without
            limitation outages for installation of equipment (including any
            outage for the installation of low NOx burners at the Roxboro 4
            Unit) required to comply with regulations or legislation in effect
            as of July 1, 1996, shall not constitute an event of force majeure
            hereunder. Written notice including full information as to the cause
            and probable extent of the event shall be furnished within ten (10)
            calendar days after the failure first occurs. Failure to provide
            such notice within the ten (10) calendar days specified herein shall
            be deemed a waiver of all rights provided pursuant to Paragraph 8.1
            with regard to the particular event or occurrence. Any interruption
            in deliveries hereunder as a result of any such force majeure event
            shall not terminate this Agreement and upon removal of the cause of
            interruption, deliveries shall be resumed.

      8.2   In the event of the enactment of any federal, state or local law,
            legislation, ordinance, rule or regulation after July 1, 1996, which
            prohibits the burning or use of the coal to be supplied hereunder or
            has the effect of requiring Buyer to purchase coal having different
            quality characteristics from those set forth in Paragraph 1.0,
            Description in order to comply with such federal, state or local
            law, ordinance or regulation, shipments hereunder may be terminated
            by Buyer

                                       12
<PAGE>

            upon ninety (90) days advance notice to Sellers; provided, however,
            that shipments under this Agreement shall not be so canceled if
            Sellers elect (i) to substitute coal from other sources and such
            coal has quality characteristics which enable Buyer to comply with
            applicable law, or (ii) to modify the operation from which the coal
            is supplied such that the quality of coal shipped shall enable Buyer
            to comply with applicable law, or (iii) to take any other step that
            enables Buyer to comply with applicable law. In the event that
            shipments are terminated pursuant to this Paragraph 8.2, Buyer shall
            remit to Sellers $3.447 per ton as liquidated damages as full and
            complete settlement of all claims and not as a penalty for each ton
            terminated. Such amounts shall be paid in accordance with Paragraph
            4.0, Payment based upon the shipment schedule established pursuant
            to Paragraph 2.0, Quantity and Delivery. Termination of shipments
            pursuant to this Paragraph 8.2 shall excuse Buyer's obligation to
            make payments for coal pursuant to Paragraph 5.3 with respect to
            those tons terminated. To the extent that such payments for coal
            have been made by Buyer with respect to terminated tons, such
            amounts shall be credited against future payments for coal to be
            made under Paragraph 5.3, or if no future payments for coal are to
            be made, Sellers shall refund such amounts to Buyer.

      8.3   In the event that (i) a force majeure event results in the physical
            inability to generate electricity at the Roxboro 4 and/or Mayo 1
            Unit(s), or (ii) a force majeure event that does not fall within
            Paragraph 8.2 above totally prevents the generation of electricity
            at Roxboro 4 and/or Mayo 1, for a period that exceeds six (6)
            consecutive calendar months in duration ("Extended Force Majeure"),
            Buyer's annual commitment to purchase coal under this Agreement
            shall be reduced by an amount equal to the number of tons not
            shipped during and as a result of the Extended Force Majaure;
            provided, however, that nothing herein shall (or shall be construed
            to) discharge or diminish Buyer's obligation to take reasonable
            steps to avoid, cure, or otherwise mitigate the effect of such an
            event of force majeure, including but not limited to acceptance of
            additional quantities hereunder at the unaffected Unit. Buyer shall
            not enter into any new spot or contract agreements for compliance
            coal for the unaffected Unit during the term of the Extended Force
            Majeure until Sellers are given the option to supply such quantities
            hereunder.

            Should Buyer expect that the Extended Force Majeure will exceed a
            total of twelve (12) months, then after the expiration of the
            initial six (6) months of the Extended Force Majeure, the parties
            shall determine whether the coal to be delivered hereunder or coal
            with different specifications than those in Paragraph 1.0,
            Description can be supplied by Sellers and consumed at Buyer's other
            coal-fired plants without causing operational problems, regulatory
            compliance issues, or breach of any contract commitments to other
            coal suppliers. If so, Sellers shall have the option to deliver such
            coal under this Agreement, and this Agreement shall be amended to
            reflect any necessary changes. If coal with different specifications
            than those in Paragraph 1.0, Description is delivered hereunder, the
            price for such coal shall be adjusted to reflect the difference in
            the quality of the coal to be substituted and any other relevant
            factors in existence at the time. Should the parties be unable to
            agree upon such an adjustment, it shall

                                       13
<PAGE>

            be determined by an independent third party agreed upon by both
            Buyer and Sellers. In the event a third party cannot be agreed upon,
            the provisions of Paragraph 18.0, Third Party Selection shall apply.

            The occurrence of an Extended Force Majeure shall not affect Buyer's
            obligation to make payments for coal as set forth in Paragraph 5.3.

      8.4   Coal not shipped as scheduled as a result of an event of force
            majeure (excluding coal not shipped due to an Extended Force Majeure
            pursuant to Paragraph 8.3) shall be rescheduled for shipment as soon
            as practicable after the cessation of the force majeure event. This
            revised schedule shall provide for delivery of such coal within
            thirty (30) months of cessation of the force majeure event.

            In the event that Sellers experience a force majeure event, the
            price applicable to rescheduled shipments shall be the lesser of the
            price applicable at the time such shipments were originally
            scheduled for shipment or the price applicable on the date of
            shipment of coal. In the event that Buyer experiences a force
            majeure event, the price applicable to such rescheduled shipments
            shall be the greater of the price in effect on the date of the
            shipment of the coal or the price applicable at the time such
            shipments were originally scheduled for shipment.

      8.5   Except as provided in Paragraph 8.8, a force majeure event,
            including an Extended Force Majeure event pursuant to Paragraph 8.3,
            shall not affect the amount or timing of payments for coal due
            pursuant to Paragraph 5.3. Such payments for coal shall be made as
            if those tons not shipped as originally scheduled as a result of the
            force majeure event were shipped as so scheduled; provided, however,
            that if such tons are not made up pursuant to Paragraph 8.4 as a
            result of Sellers' inability to supply such tons, Buyer shall
            receive a credit for payments for coal made pursuant to Paragraph
            5.3 with respect to any tons not shipped.

      8.6   Twelve (12) months prior to any renewal of a contract between the
            United Mine Workers of America ("UMWA") and the employers of
            employees represented by the UMWA, or any future labor organization
            representing such employees, reasonable efforts shall be made by
            Buyer and Sellers to mutually agree to accelerate shipment of coal
            prior to the anticipated commencement of the expiration of such
            contract. Such acceleration of coal shipments (hereafter referred to
            as "Accelerated Tonnage"), which shall be shipped to Buyer and shall
            meet the specifications herein, is in anticipation of the
            interruption of coal supplies which might result by reason of the
            expiration of such contract. The price for all Accelerated Tonnage
            shall be the price in effect at the time the coal was originally
            scheduled to be shipped pursuant to Paragraph 5.1. Neither the
            amount nor the timing of the payments for coal due under Paragraph
            5.3 with respect to such tons shall be affected by such acceleration
            and such payments for coal shall be made as if shipment of the
            Accelerated Tonnage had not occurred.

                                       14
<PAGE>

      8.7   The parties shall mutually determine within thirty (30) days of the
            end of any disruption described in Paragraph 8.6 or any disruption
            resulting from a railroad labor strike, the amount of coal that
            Sellers were unable to ship based upon the tons scheduled to be
            shipped during the period of such disruption, less any Accelerated
            Tonnage. After such determination, the parties shall mutually
            schedule the shipment of such coal so that Sellers may reasonably
            produce and ship same over the next succeeding thirty (30) month
            period. The price for such coal shall be the price in effect at the
            time of shipment.

      9.0   Quality Information. On request, Sellers shall furnish to Buyer
            information sufficient to show the quality of coal to be shipped
            from any seam or source, including proximate analysis, mineral ash
            analysis, ultimate analysis, or any other quality information
            requested by Buyer with respect to coal shipped under this Agreement
            that is existing and reasonably available to Sellers.

            On request, Buyer shall furnish to Sellers any quality analysis
            performed by it or on its behalf with respect to shipments
            hereunder.

      10.0  Title. The title to the coal covered by this Agreement shall pass
            directly from Sellers to Buyer as soon as the coal is loaded into
            railcars at the mine.

      11.0  Consignment. The coal covered by this Agreement is intended for
            consumption at Buyer's Roxboro 4 and/or Mayo 1 Units. However, at
            any time and from time to time during the term of this Agreement,
            Buyer shall have the right to have all or any part of the coal
            covered by this Agreement consigned to any other destination,
            provided that Buyer gives Sellers five (5) days written notice of
            such consignment; that Buyer causes Sellers to be furnished with
            railroad cars, applicable railroad tariffs, and adequate
            instructions for shipment of coal so consigned; and that such
            consigned shipments do not impose additional obligations on Sellers
            greater than those provided for in Paragraph 2.0, Quantity and
            Delivery and Paragraph 2.1, Weights.

            In any case of consignment pursuant to this Paragraph, Buyer shall
            remain fully liable for the obligations set forth in this Agreement,
            and Buyer shall pay for such coal, including quality adjustments
            pursuant to Paragraph 6.0, Remedies for Quality Deviations,
            utilizing the same freight rates which would have been effective had
            the shipment(s) not been reconsigned by Buyer. Sellers shall not
            have any contractual responsibility to the consignee, and such
            consignee shall have no rights, privileges or responsibilities
            hereunder.

      12.0  Access. Buyer or its designated representatives shall have access,
            at reasonable times and without interfering with production, to
            Marrowbone or any affiliate of Sellers producing coal covered by
            this Agreement. In addition, Sellers shall exert reasonable efforts
            to ensure that Buyer or its designated representatives shall have
            access, at reasonable times and without interfering with production,
            to mines owned by third parties producing coal covered by this
            Agreement. Such access shall be for the purpose of inspecting said
            mines and related facilities and

                                       15
<PAGE>

            examining the quality records. Buyer shall also have access to
            Sellers' or its supplier's books and records during normal business
            hours as necessary to understand and evaluate any proposed price
            adjustment submitted to Buyer by Sellers in accordance with the
            provisions of Paragraph 5.2. Sellers shall provide Buyer with access
            to such books and records within two (2) weeks of Buyer's written
            request, and shall make all such books and records available at the
            mine or at Sellers' corporate offices. Sellers or their designated
            representatives shall have access, at reasonable times and without
            interfering with operations, to the facilities of Buyer to observe
            the sampling and analysis of any coal sold hereunder.

      13.0  Waiver. No waiver of any breach of this Agreement shall be held to
            be a waiver of any other breach. Except with respect to remedies as
            set forth in Paragraph 6.0, Remedies for Quality Deviations, all
            remedies afforded under this Agreement shall be in addition to every
            other remedy provided herein or by law.

            1995 ("Agreement")

Dear Mr. Davis:

Please refer to Article XlV, Payments of the Agreement referenced above.
Confirming discussions between the parties, the last paragraph of Article XIV
shall be deleted in its entirety and replaced with the following:

      "d)   Such payments shall be made by Buyer to Seller via wire or
            electronic transfer of immediately available funds (in United States
            currency) to the following account:

I believe the preceding accurately reflects our discussions. If you concur,

3)    Assuming CP&L provides notice at least 90 days prior to the 1st day of the
      4th quarter of 2003 CP&L shall have the option in its sole discretion to
      receive up to fifty thousand (50,000) of the Deferred Tons per month
      (approximately 5 unit trains per month) during the 4th quarter 2003. The
      50,000 tons may be requested in any unit train combination under the Wolf
      Creek and Marrowbone Agreements (i.e. 0 Wolf Creek and 5 Marrowbone to 2
      Wolf Creek and 3 Marrowbone to 5 Wolf Creek and 0 Marrowbone). The amount
      of tons received under this option from each Agreement (Wolf Creek and
      Marrowbone) shall reduce the Deferred Tons remaining to be received under
      the corresponding Agreement (Wolf Creek and Marrowbone).

      After December 31, 2003 CP&L will take delivery of the Deferred Tons
      remaining over any time period or periods that it deems acceptable prior
      to the expiration of the corresponding Agreement. CP&L will provide 30
      days prior notice and the Deferred Tons will not exceed a total of 167,000
      tons per month (maximum of 100,000 tons per month Wolf Creek and 67,000
      tons per month Marrowbone).

      The price for the Deferred Tons, regardless of when the tons are received,
      shall be the contract price that was in effect for each Agreement at the
      time of deferral, which is listed below in the Deferred Tons Pricing
      Table.

Re:   Amended and Restated Agreement for the Sale and Purchase of Coal Dated
      July 1, 1996, Between CP&L and Mountaineer Coal Development Company, d/b/a
      Marrowbone Development Company, and Bluegrass Coal Development Company
      (the "Marrowbone Contract") and Agreement for Sale and Purchase of Coal
      Dated July 1, 1996, Between CP&L and Franklin Coal Sales Company (the
      "Franklin Contract")

Dear Dwain:

      This letter shall confirm our agreement in principle with respect to the
Marrowbone Contract and the Franklin Contract.

      We have agreed that simultaneously with the execution of this letter
agreement the parties will execute, acknowledge and deliver the attached
Amendment No. Three to the Marrowbone Contract which effectively reduces the
tonnage requirement thereunder to 1.5 million tons per year through the
remainder of the contract. In connection therewith, upon execution of the
Amendment the following actions will be taken:

      1.    Horizon will immediately file in its bankruptcy proceeding
            appropriate Motions for the assumption of the Marrowbone Contract
            and the Coal Supply Agreement, dated December 29, 2000, between
            Horizon Natural Resources Sales Company, f/k/a AEI Coal Sales
            Company, Inc., and Massey Coal Sales Company, Inc., d/b/a Massey
            Utility Sales Company (the "Massey Contract"). In addition, Horizon
            will request an expedited review and approval of this assumption of
            executory contracts.

      2.    Horizon will immediately file a notice of rejection of the Franklin
            Contract under the procedures previously adopted for rejection of
            executory contracts in its bankruptcy proceeding.

      At such time as a non-appealable Order approving the assumption of the
Marrowbone Contract and the Massey Contract has been entered by the Bankruptcy
Court, Horizon will execute and deliver to CP&L a letter of confirmation in the
form attached whereby Horizon (i) dedicates the coal to be received under the
assumed Massey Contract for fulfillment of its obligations under the Marrowbone
Contract, as amended and assumed; and (ii) covenants and

<PAGE>

Mr. Dwain K. Lanier
Executive Director, Fossil Fuels
Progress Energy-Carolinas, Inc.

Page 2

agrees that it will not transfer or assign the Massey Contract without the prior
written consent of CP&L.

      We acknowledge and agree that nothing contained in this agreement is
intended to be a waiver or release of any outstanding claims or disputes
relating to light loading charges imposed by the Norfolk Southern Railroad and
Horizon agrees to accept such ultimate responsibility as may be determined to
exist pursuant to the terms and provisions of the Marrowbone Contract. Horizon
and CP&L shall work together in a good faith effort to determine a reasonable
light loading claim amount and resolve this matter within 90 days of the date
hereof.

      If the foregoing properly reflects our agreement with respect to these
matters, please so indicate by signing and dating this letter in the space
provided below and return it together with an executed Amendment No. Three to me
at your earliest convenience. This agreement may be executed via facsimile and
in counterparts, each of which, when taken together, shall constitute an
original. We will then instruct our bankruptcy counsel to immediately implement
the actions described above.

                                            Yours truly,

                                            /s/ Marc Merritt

      A. BUYER and SELLERS are parties to that certain Amended and Restated
Agreement for Sale and Purchase of Coal dated July 1, 1996, which, along with

125,000 tons per month through the end of the year); the Total Tonnage for each
of calendar years 2004, 2005 and 2006 is reduced from 2,750,000 tons to
1,500,000 tons; and the Total Tonnage under the Contract shall be reduced from
28,875,000 tons to 23,775,167 tons.

      2. Conflicting Language. To the extent that any language contained in the
Contract conflicts with any language contained in this Amendment, the language
contained in this Amendment shall control.

<PAGE>

      3. Facsimile and Counterparts. This Amendment may be executed via
facsimile and in counterparts, each of which, when taken together, shall
constitute an original.

      4. Full Force and Effect. Except as expressly amended by this Amendment,
the Contract remains unchanged and in full force and effect, and is hereby
ratified and reaffirmed.

      IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Amendment as of the date first set forth above.
