to supply such coal.

     During the term of this Agreement, Anker shall sell and deliver to ER&L,
and ER&L shall purchase and accept from Anker, all of ER&L's total coal
requirements for AES' use at the Facility, which presently are estimated to
equal approximately 200,000 Tons of Coal from the Financial Closing Date until
the In-Service Date and to equal approximately 600,000 Tons of Coal per year
from the In-Service Date through the remaining term of this Agreement; it being
understood by the Parties that such estimates are for informational purposes
only, and that the actual quantities of Coal to be supplied hereunder shall be
determined by, among other things, the actual availability and operating
performance of the Facility as well as the quality and other characteristics of
the coal used at the Facility.

     Section 3.3. Quality. The Coal delivered by Anker to ER&L hereunder shall
have the following qualities and characteristics:

          (a) Monthly Specifications. The As-Delivered Coal delivered during
each calendar month must satisfy the following minimum and maximum
specifications on an as-received basis (the "Monthly Specifications"), with such
compliance to be determined on the basis of the weighted average of the analyses
of said deliveries performed pursuant to Section 4.4 hereof:



                                                       ASTM Method

provided, that if the sulphur removing equipment in the Facility removes more
sulphur than presently contemplated, so that the sulphur emissions of the
Facility are less than the standards set forth in the Facility's permit, and AES
increases the Monthly Specification for Sulphur content under its agreement with
ER&L, ER&L shall correspondingly increase this Agreement's Monthly Specification
for Sulphur content as an accommodation to Anker and may if appropriate increase
the Individual Specification for Sulphur content to a reasonably higher
percentage which shall in no event cause ER&L to purchase Coal hereunder in a
manner which would cause a violation of the Facility's permit.

          (b) Individual Specifications. Each individual barge load of
As-Delivered Coal hereunder must satisfy the following minimum and maximum
specifications on an as-received basis (the "Individual Specifications"), with
such compliance to be determined on the basis of the analyses of the Coal
contained in said barge load pursuant to Section 4.4 hereunder:



                                                        ASTM Method
                                                        -----------
                                                  
     Moisture content --                  [*](2)            D-3173

     Ash content --                       [*](2)            D-3174

     Sulphur content --                   [*](2)            D-3177

     High Heating Value

     Delivered size --                    [*](2)

     Fines --                             [*](2)


provided, that if, after taking into account (A) the quantities, qualities and
characteristics of all Coal previously supplied hereunder during the
then-current month, (B) the quantities of Coal to be supplied hereunder from
each particular source or sources during the remainder of such month, and the
qualities and characteristics of such source or sources, and (C) any other
relevant factors, ER&L reasonably determines that the Monthly Specifications
will not be met by the Coal supplied and to be supplied during such month, then
ER&L may request reasonable changes of any or all of the Individual
Specifications to be met by subsequent individual deliveries for such month so
as to ensure that the total quantity of Coal supplied during such month will
satisfy the Monthly Specifications.

     It is understood that an individual barge load may not be a full barge load
of Coal because from time to time, one-third (1/3) of the full barge load will
consist of limestone.

     All Coal delivered hereunder shall be substantially free from impurities,
including but not limited to, bone, slate, earth, rock, pyrite or wood. No oil
or other material will be added to change the natural heating value of the Coal,
however, a freeze protection agent may be added at ER&L's request and expense as
provided in section 4.1(c) (2) hereof. In addition, Anker shall, at ER&L's
request and provided Anker's cost of supplying Coal is not significantly
increased, use its reasonable efforts during any wet periods at the Facility to
keep the Fines of Coal delivered hereunder to a minimum. Each trainload of Coal
shall be loaded in a manner that will reasonably ensure a uniform consistency of
size and quality. At Anker's request, ER&L shall blend trainloads of Coal in
accordance with Anker's instructions at no additional charge during the dumping
of the rail cars and during the loading of the barge; provided, however, that
ER&L shall not be required to blend Coal from more than two trainloads at any
one time, or to alternate rail cars more frequently than every two rail cars.
After the rail cars are loaded, Anker shall give ER&L adequate prior notice and
instructions for blending the Coal.

          (c) Change of Individual Specifications. ER&L has advised Anker that
under the AES Agreement, AES has the right to make certain limited changes in
the Individual Specifications within two (2) years after the first delivery of
Coal. In such event, AES will be obligated to pay certain rate increases to
ER&L. Anker and ER&L agree that if AES makes such changes, identical changes in
the Individual Specifications will be made under this Agreement. The procedure
for making such changes and for making corresponding Purchase Price adjustments
shall be as follows:

          (1) If required by AES, ER&L may elect to modify the Individual-
Specifications in accordance with Sections 3. 3 (c) (2) and 3. 3 (c) (3) hereof.
Any such election shall designate new specifications from the following table,
and the corresponding amount shown below shall be added as an adjustment to the
Purchase Price for each Ton of Coal hereunder:

     Section 3.4. Adjustments to Specifications.

     (a) Initial Tests. Within twenty (20) days of a request from ER&L, Anker
shall deliver to ER&L Coal consistent with the Monthly Specifications and in
sufficient quantities such that AES can complete, prior to the actual
performance testing of the Facility under the Construction Contract, a test burn
demonstrating the qualities of the Coal and a similar test demonstrating the
qualities of the limestone to be burned with the Coal. If ER&L determines after
either such test that the Coal is not satisfactory for the efficient and
economic operation of the Facility, ER&L shall notify Anker of adjustments in
the appropriate Monthly and Individual Specifications that are necessary for the

confidential treatment filed with the Securities and Exchange Commission (the
"Commission"). The omitted portions, marked by "[*]," have been filed separately
with the Commission.

   11

Facility to operate in such a manner. ER&L shall not make a determination that
this Coal is not satisfactory unless AES has made a similar determination.

          (b) Operating Constraints on Size. If Coal delivered pursuant to this
Agreement causes mechanical or operational problems due to clogging in the
material handling and feed systems of the Facility, ER&L shall notify Anker of
adjustments in the Monthly and Individual Specifications for size as to the Coal
or Fines that are necessary (without making any changes in the physical plant of
the Facility) for the Facility to operate without said problems. ER&L shall not
so notify Anker unless AES has given ER&L similar notification.

          (c) Regulatory Changes. If AES is required as a result of any
Applicable Law or Permit (given the then existing physical plant of the
Facility) to burn Coal having specifications different from those set forth
herein, ER&L shall notify Anker of the adjustments to the Monthly and Individual
Specifications that are required thereby. ER&L shall not so notify Anker unless
AES has given ER&L similar notification. Anker shall commence to supply Coal
conforming to the revised specifications within fifteen (15) days of such notice
or such time as is required pursuant to such Applicable Law or Permit, whichever
is later.

          (d) Price Adjustment. If Anker is to supply Coal conforming to new
specifications as a result of adjustments made pursuant to Sections 3. 4 (a) ,
(b) or (c) hereof, the price therefor shall be negotiated by ER&L and Anker in
good faith to reflect such adjustment; but only such adjustment, to the
specifications, and such pricing shall take into account among other things any
cost increases and the benefit of any bargain accruing to ER&L and/or Anker
under this Agreement as a result of such specification adjustment and shall
reflect the relative significance or insignificance of any revisions to the
specifications as compared to all the other factors taken into account in
arriving at the Purchase Price. If the Parties fail to reach agreement within
thirty (30) days of ER&L's notice to Anker of revisions, the matter of price
revisions shall be referred to arbitration pursuant to Article XIII hereof, and
pending resolution of such dispute deliveries of Coal shall be continued in
accordance with the provisions of this Agreement.

          (e) Termination for Non-Supply. If Anker does not on a timely basis
commence to supply Coal conforming to the revised specifications as contemplated
in Section 3.4(a), (b) or (c) hereof, ER&L may terminate this Agreement
immediately upon providing 30 days' prior written notice of termination to
Anker.

          (f) Consultation by the Parties. ER&L shall consult with Anker if AES
complains about the quality or quantity of Coal being delivered to the Facility
and such complaints will have an adverse effect on Anker under this Agreement,
or if AES indicates to ER&L that it will or may wish to modify Individual or
Monthly Specifications pursuant to Sections 3.4(a), (b) or (c) hereof.

   12

Section 3.5. Sources; Reserves

          (a) Sources. The Coal sold and purchased hereunder shall be produced
from Mines Sources. Anker shall not deliver Coal produced from any source other
than Mines Sources unless (i) and only to the extent a Force Majeure event
prevents such delivery or (ii) ER&L has given its prior written consent, which
consent shall not unreasonably be withheld. Anker may propose new Mines Sources
by requesting, from time to time, ER&L's consent to the approval of specific
coal mines, coal suppliers or coal seams. At ER&L's option, such consent may be
conditioned upon (i) ER&L's satisfaction with test analyses of the coal from
such other source, (ii) provision by Anker of amounts of coal from such source
sufficient for performing satisfactory test burns or similar tests thereof,
(iii) provision of other means of proof, satisfactory to ER&L, of the compliance
of such coal with the specifications set forth herein, and (iv) ER&L's ability
to obtain AES' consent if ER&L deems it necessary to do so. Deliveries of Coal
hereunder from any source other than Mines shall comply with and be subject to
all terms and conditions of this Agreement; ER&L's consent to any new Mine
Sources shall not be construed as an acknowledgement by ER&L that any delivery
from such new Mine Sources so complies.

          (b) Reserves. Anker represents and warrants that it has the legal
right to sell, and that Anker and its affiliates named in Annexes B and C hereto
now own, lease or otherwise have the legal right to mine and sell, and have
dedicated or will dedicate to the performance of this Agreement on or before the
Financial Closing Date, a sufficient number of Tons of recoverable Coal from the
Mines (the "Coal Reserves") to enable Anker to supply Coal in accordance with
the provisions of this Agreement. General descriptions of the Coal Reserves are
set forth in Annex A hereto, which Annex is incorporated herein by this
reference. Anker warrants that the Coal will meet the terms and conditions of
this Agreement.

          (c) Transfer of Reserves. If Anker or any of its affiliates sells,
leases, contracts to sell or otherwise transfers or agrees to transfer to others
any of its interests in the Coal from the Coal Reserves, Anker agrees such
transactions will neither jeopardize Anker's ability to supply the total
quantity of Coal required under this Agreement nor interrupt any scheduled
deliveries hereunder.

          (d) Anker Affiliates. The Anker affiliates which will be supplying
Coal and/or Waste disposal services as described in this Agreement are those
named in the agreements attached hereto as Annexes B and C.

                                   ARTICLE IV

                                DELIVERY OF COAL

     Section 4.1.   Delivery Points; Arrangements; Procedures.

          (a) Delivery Points. This Agreement is a "destination" contract in
which Anker agrees to deliver Coal F.O.B. barge the Facility at the Coal
Delivery Point. The Coal Delivery Point shall be located at the Facility's dock
facilities on the Thames River at a point designated by AES. Notwithstanding any
other provision of this Agreement which may be construed to the contrary, all
risks of loss and damage in, and any liability arising out of or in connection
with, transit (commencing from the tender of the Coal for carriage on the rail
cars and continuing until delivery of the Coal to ER&L at the Coal Delivery
Point) shall be borne by ER&L. Without limiting the generality of the preceding
sentence, ER&L shall have full responsibility for the Coal while it is in the
possession of ER&L or ER&L's subcontractors (including without limitation CSXT),
including the obligation to pay Anker its full, actual loss for any loss or
damage to the Coal, and ER&L shall indemnify Anker from and against any and all
loss or liability asserted against Anker by any third party arising out of or in
connection with the transportation of the Coal by ER&L or any carrier arranged
by ER&L.

          (b) Assurances as to Delivery Arrangements. ER&L shall provide all
rail and barge transportation arrangements and services, and all related
handling and ancillary arrangements and services, necessary to accomplish the
transportation of the Coal hereunder from its tender by Anker for carriage until
its delivery at the Coal Delivery Point. From time to time, Anker shall provide
ER&L within ten (10) days of any request by ER&L with evidence that demonstrates
to ER&L's satisfaction that Anker is and shall continue for the term of this
Agreement to be able to provide timely tenders of Coal as required hereunder. If
Anker fails to provide such reasonable assurances within fifteen (15) days of
ER&L's request, Anker shall be in default of this Agreement and ER&L may pursue
its rights and remedies in accordance with Section 10.2 hereof, including its
rights thereunder to terminate this Agreement.

          (c) Procedures.

          (1) Tender for Carriage. All Coal shall be shipped by Anker to ER&L
hereunder via CSXT in unit trains of 7,000 Tons, or smaller if the Coal is to be
transported in a barge which will also transport limestone, and shall be in
accordance with CSXT's instructions and rules regarding unit train permits,
loading, safety and other procedures. All tenders of shipments of Coal to ER&L
shall be covered by a mine card on which Anker will show the following:

                     "Subject to Contract ICC-CSXT-C-04070"

or such other number as may from time to time be provided by ER&L as the correct
reference to ER&L's rail transportation contract with CSXT.


   14

          (2) Freeze Protection. When requested by ER&L, Anker shall apply a
freeze protection agent as the Coal is loaded in the cars in amounts as may be
agreed to from time to time by the Parties. The price for the freeze
conditioning (material and application) shall be [*](5) for each pint per Ton of
Coal, which ER&L agrees to pay to Anker promptly upon receipt of Anker's invoice
therefor. The freeze protection price shall be subject to escalation as provided
in Section 6.3.

     Section 4.2. Delivery Schedule.

          (a) Scheduling Determinations. By the fifteenth (15th) day preceding
the start of each calendar quarter during the term of this Agreement, ER&L shall
provide Anker with an estimate of the amount of Coal to be delivered during such
quarter pursuant to this Agreement. In addition, on or before the twenty-eighth
(28th) day of each calendar month during the term of this Agreement, ER&L shall
deliver to Anker written notice of the estimated amount of Coal to be delivered
to ER&L during the next succeeding calendar month. Upon receipt of such notice,
Anker shall confer with ER&L and the Parties shall arrange a delivery schedule
for the month consistent with AES's needs; provided, however, that upon ER&L's
request Anker shall use its best efforts to modify said schedule to the extent
necessary to accommodate ER&L's changing Coal requirements. In the event either
Party learns of a probable interruption in a scheduled delivery of Coal
hereunder, such Party shall promptly notify the other Party.

          (b) Loading Arrangements. At the time Anker and ER&L confer, they
shall set the days for loading the unit trains, provided, however, that if the
schedule calls for Anker to load Coal on Sundays or public holidays, the
schedule shall be adjusted at Anker's request to permit loading on the day prior
or subsequent to such Sunday or public holiday, but such adjustment shall not
delay the schedule of the barge. If the empty cars of the unit train are
tendered on the day set, Anker agrees to load the cars within the time period
set by CSXT's Original Applicable Tariff and, if the cars are not so loaded, to
pay the demurrage charges provided in such tariff. If the empty cars are
tendered on a day other than the day set, Anker agrees to load the cars within
the time period set by CSXT's Original Applicable Tariff starting on the day set
(if the empty cars arrived early) or starting on the first full working day
beginning at 8:00 A.M. the cars are available (if the empty cars arrived late) .
If the cars are not so loaded, Anker agrees to pay the demurrage charges
provided in the tariff, subject to the provisions of Section 6.4(c) hereof. It
is agreed that for purposes of the demurrage payments by Anker contemplated by
this Agreement, the time periods set for loading in the Original Applicable
Tariff will be the time periods as set by such tariff on the date of this
Agreement and that such time periods will not thereafter change even if such
tariff is amended or changed.

     Anker shall have no responsibility, whether for the payment of demurrage
charges or otherwise, for any delays subsequent to the loading of the cars,
including any delays in unloading the cars and loading or unloading the barges,
unless caused by Anker's acts of

confidential treatment filed with the Securities and Exchange Commission (the
"Commission"). The omitted portions, marked by "[*]," have been filed separately
with the Commission.


   15

commission or omission. ER&L shall indemnify Anker from and against any and all
loss or liability arising out of or in connection with such delays for which
Anker is not responsible.

          (c) Notices to CSXT. At least forty-eight (48) hours prior to each
tender of Coal to CSXT for carriage hereunder, Anker shall give notice thereof
by telephone to CSXT's Director of Unit Trains, or such other person designated
in writing by ER&L to Anker.

     Section 4.3. Invoices. Anker shall deliver to ER&L an invoice for each
barge load of Coal after delivery of such Coal to AES at the Coal Delivery
Point, provided that in the event of a delay of more than thirty (30) days in
the delivery of Coal after it is loaded on rail cars, Anker may deliver its
invoice at the end of such thirty (30) day period. Said invoices shall specify
the tonnage delivered with appropriate weight documentation, specifications of
the Coal delivered, the rail origin point and dates, and the sources of the
Coal, and shall reflect the results of all analyses conducted pursuant to
Section 4.4. hereof. ER&L agrees to promptly provide necessary documentation
input required by Anker to prepare the invoices required herein, and if such
documentation is not so provided, Anker may prepare invoices based on its
reasonable estimates.

     Section 4.4. Analysis. Each shipment of Coal hereunder shall be sampled and
analyzed at Baltimore, Maryland.

          (a) Sample. At least one representative sample of each barge shipment
at Baltimore shall be taken and given to an independent laboratory agreed to by
Anker and ER&L (the "Lab") for analysis. The sampling shall be random, and the
analysis shall be performed in accordance with methods approved by the American
Society for Testing Materials (ASTM) consistent with Section 3.3 hereof or such
other methods as may reasonably be agreed upon by Anker and ER&L. Either Party
shall have the right to have a representative present at any and all times to
observe such sampling and analysis. The Lab shall furnish the parties with a
copy of the report of each analysis within 36 hours of completion of loading of
the barge. The Parties shall share equally the cost of the sampling and Lab
analysis.

          (b) Replacement of Lab. If either party becomes dissatisfied with the
Lab, the Parties will mutually agree to another Lab.

     ER&L shall at all times keep Anker informed of the identity of the
laboratory performing the analyses under the AES Agreement and consult with
Anker regarding any changes thereof.

          (c) Analysis. The Lab shall divide all samples into not less than two
(2) parts and put them in suitable airtight containers, the second container in
each case to be held available for a period of sixty (60) days after the date on
which the shipment from which such sample was taken was delivered. If the Lab is
the same laboratory AES and ER&L use, the results of the Lab's analysis shall be
binding on Anker and ER&L. If


   16

AES and ER&L use a different independent laboratory to analyze representative
samples of the same shipment taken at Baltimore, and if that laboratory's
analysis results are materially different from the Lab's analysis, the second
container shall be analyzed by an independent laboratory selected by agreement
of ER&L and Anker, or by the Lab if ER&L and Anker are unable to agree on an
independent laboratory before the fifty-fifth day of the aforesaid 60-day
period, and the results of such analysis shall be binding.

          (d) Procedure If Coal Is Rejected. ER&L has advised Anker that under
the AES Agreement, AES may reject a barge load of Coal in whole or in part at or
before the time of unloading the barge at the Facility. In the event Coal is so
rejected, Anker and ER&L agree they will attempt to persuade AES to accept such
Coal, including arranging with AES for additional sampling and testing of the
Coal at the Coal Delivery Point and/or Facility.

     In the event AES finally rejects Coal delivered by ER&L, or in the
event ER&L reasonably believes AES will reject it, ER&L may reject such Coal if
the Coal remains in the barge and is rejected on the basis of either visible
impurities or of the analysis results of samples taken in Baltimore, or if the
Coal has been unloaded from the barge and it is unusable; provided, however,
that Anker shall not be subject to rejection of Coal solely as a result of
damage (including contamination) which occurred in transit.

     Section 4.5. Weighing. For each delivery hereunder of Coal to the Coal
Delivery Point, weights shall be determined either by CSXT using its normal
railroad scales or by barge draft survey, and the choice of the method for
determining weights for such delivery under the AES Agreement shall apply for
purposes of this Agreement. The railroad weight certificates or draft survey
certificates shall be conclusive evidence of the quantity of Coal in any
shipment.

     Section 4.6. Non-Complying Deliveries.

          (a) If any Coal tendered for delivery by Anker hereunder fails to meet
the applicable Individual Specifications set forth herein or to conform with the
timing and quantities, determined pursuant to Section 4.2 hereof and AES rejects
a barge shipment of Coal in whole or in part and advises ER&L, ER&L shall have
the right to reject such Coal as set forth in Section 4.4 (d) hereof, and ER&L
shall use its reasonable efforts to so advise Anker before the shipment is due
to be unloaded at the Facility, and notify Anker of the rejection and the
reasons therefor. Anker shall promptly remove any deficient Coal shipment so
rejected at its own expense and cure any deficiency in supply caused thereby (to
the extent that ER&L has not purchased replacement quantities pursuant to
Section 4.6 (c) hereof).

          (b) If in any thirty (30) day period Anker makes two (2) or more barge
shipments of Coal that would be subject to rejection under Section 4.6 (a)
hereof and which are not cured by Anker within ten (10) days of the
non-conforming delivery (whether or not such shipments are accepted by ER&L
under Section 4.6 (a) hereof) ER&L may (i) request that Anker provide at its own
expense assurances to ER&L's


   17

reasonable satisfaction that future shipments of Coal will comply with the terms
and conditions of this Agreement, or (ii) upon fifteen (15) days' advance
written notice, direct Anker to suspend further shipments of Coal, which
suspension shall be considered to be commercially reasonable. Such suspension
shall continue until the earlier of (i) ER&L's notice to Anker to resume
deliveries hereunder, and (ii) the provision of the assurances re- quested by
ER&L. If Anker fails to provide such assurances within fifteen (15) days of
ER&L's request, Anker shall be in default of this Agreement and ER&L may pursue
its rights and remedies under Section 10.2 hereof, including its right
thereunder to terminate this Agreement.

          (c) If Anker fails to cure any rejected shipment pursuant to Section
4.6 (a) hereof after notice from ER&L, then ER&L shall have the right within
thirty (30) days to purchase replacement coal from alternative sources, and
Anker shall use its best efforts to assist ER&L in finding and acquiring such
replacement supplies. In the event that ER&L purchases replacement quantities of
coal pursuant to this Section 4.6 (c), Anker shall reimburse ER&L for the
difference, if any, between (1) the costs incurred by ER&L in purchasing said
replacement supplies minus (2) the amounts that would otherwise be payable by
ER&L to Anker hereunder for the supplies so replaced (including any amounts
which would in turn be payable by Anker to or on behalf of ER&L, or would be
credited to ER&L, for transportation, handling and ancillary services relating
to such supplies). Anker shall make such payment within thirty (30) days of
receipt from ER&L of an invoice documenting such excess costs together with
appropriate supporting documentation.

     Section 4.7. Title. Anker warrants that title to all Coal delivered to ER&L
hereunder will be good and merchantable and its transfer lawful, and that
such Coal will be free of any lien (except carriers' liens) , claim, demand,
security interest or other encumbrance. Title to the Coal purchased and sold
hereunder shall pass from Anker to ER&L upon acceptance of delivery to ER&L at
the Coal Delivery Point, subject to ER&L's right to reject Coal under Section
4.6 hereof or in accordance with Applicable Laws.

                                    ARTICLE V

                              DISPOSITION OF WASTE

     Section 5.1.  Removal and Disposal Obligations.

          (a) General. ER&L shall remove the Waste from the Waste Removal Point
and transport all the Waste to the rail siding serving the Waste Destination
Point. Unless the Parties otherwise agree, Anker shall dispose of all Waste
which it is required to dispose of pursuant to this Article V, whether such
Waste is in the form of Pelletized Waste or Dry Waste. The general procedure for
removal and delivery of Waste shall be as follows:


   18

          (1) Construction of Pelletizing Facility. ER&L shall construct at or
near the Waste Removal Point a pelletizing facility (the "Pelletizing Facility")
which will convert the form of the Waste into free-flowing spherical pellets
capable of being transported and handled without generating a significant amount
of dust ("Pelletized Waste"). It is anticipated that AES will purchase the
completed Pelletizing Facility. In consideration for ER&L's guarantee that the
Pelletized Waste will have the aforesaid properties, Anker will reimburse ER&L
for a portion of the cost of constructing the Pelletizing Facility. The amount
of such reimbursement shall be [*].(6) Such reimbursement shall be payable on
completion of construction and acceptance of the Pelletizing Facility by AES,
against ER&L's invoice accompanied by appropriate supporting documentation. In
the event that this Agreement, or Anker's obligation to dispose of Waste
hereunder, is terminated prior to the expiration of the term of this Agreement
for reasons other than Anker's willful breach, ER&L shall refund Anker's [*](5)
payment; provided, however, that if such termination occurs after the fifth
(5th) anniversary of the date Anker made its payment, the amount of such refund
shall be reduced by [*](5) for each full year elapsed after such fifth (5th)
anniversary date.

          (2) Removal and Delivery of Pelletized Waste. It is contemplated that
when the Pelletizing Facility is completed, the Waste shall be converted into
Pelletized Waste at the Pelletizing Facility. The Parties anticipate that the
Pelletized Waste will be transported by barge from the dock at the Waste Removal
Point to a dock in Baltimore, Maryland, and will be transported by rail from
Baltimore, Maryland to the rail siding serving the Waste Destination Point.

          (3) Removal and Delivery of Dry Waste. It is contemplated that prior
to the completion of construction of the Pelletizing Facility, and from time to
time thereafter, ER&L will remove Dry Waste from the Waste Removal Point. ER&L
shall transport the Dry Waste to the rail siding serving the Waste Destination
Point. The Parties anticipate that the Dry Waste will be transported by rail
from the Waste Removal Point to the rail siding serving the Waste Destination
Point.

          (4) Alternate Disposition; Sale. At any time prior to the actual or
constructive placement at the Waste Disposal Site of rail cars containing Waste,
the Parties may arrange, in accordance with the provisions of this Agreement,
for the disposition of the Waste by a means other than its disposal by Anker at
the Waste Disposal Site, including, without limitation, the sale of the Waste to
a third party. Any such arrangement shall be expressed in writing; in the event
of an emergency, the Parties shall attempt to expedite such agreement. If either
Party proposes the sale of Waste to a third party, the terms of any such sale
shall require the approval of both Parties.

          (b) Certain Obligations of ER&L. ER&L shall not agree, without Anker's
consent, to any change in the AES Agreement which modifies ER&L's rights to
dispose of the Waste. Notwithstanding any other provision of this Agreement
which may be

   19

construed to the contrary, all risks of loss or damage in, and any liability
arising out of or in connection with, the transportation of the Waste from the
Waste Removal Point to the Waste Destination Point shall be borne by ER&L.
Without limiting the generality of the preceding sentence, ER&L shall have full
responsibility for the Waste while it is in ER&L's possession as though ER&L
were a common carrier as to the Waste, and ER&L shall indemnify Anker from and
against any and all loss or liability asserted against Anker by any third party
arising out of or in connection with the transportation of the Waste by ER&L or
any carrier arranged by ER&L, except to the extent, if any, that such loss or
liability result from Anker's negligence.

          (c) Disposal obligations of Anker. Anker shall dispose of all
Pelletized Waste and Dry Waste delivered by ER&L to the Waste Disposal Site (or
at another site if required under Section 5.3 (b) hereof) in a safe and lawful
manner, in accordance with Applicable Laws and Permits governing transport from
the rail siding to the Waste Disposal Site and disposal, and in accordance with
the terms and conditions of this Agreement. Notwithstanding any other provision
of this Agreement, however, Anker shall not be obligated hereunder to dispose of
waste other than fly ash and bottom ash or to dispose of any material if such
material may not be handled and disposed of in compliance with Applicable Laws
and Permits.

          (d) Non-Complying Deliveries. In the event that ER&L delivers to Anker
any waste or other material that Anker is not required to dispose of pursuant to
the provisions of Section 5.1(c) hereof, Anker shall have the right to reject
such shipment. In the event that ER&L delivers to Anker any Waste which Anker
determines, upon visual inspection, cannot be unloaded and handled at the Waste
Disposal Facility without the use of equipment, operations, or periods of time
which are materially different from the norm for the Waste Disposal Facility,
Anker shall have the right (but not the obligation) to instruct ER&L to set
aside such rail cars until such time as ER&L and Anker shall have agreed upon
special arrangements, including additional compensation, for the disposal of
such Waste, and during such period all costs incurred as a result of or in
connection with such Waste and the setting aside of such rail cars shall be
borne by ER&L.

     Section 5.2. Quantity. During the term of this Agreement, unless prohibited
by a change in Applicable Laws or Permit rules or otherwise excused hereunder,
and unless the Parties arrange in accordance with the provisions hereof for
another disposition of the Waste, Anker shall dispose of all Waste, which
presently is estimated to equal approximately [*](7) Tons per year during the
term of this Agreement, it being understood by the Parties that such estimate is
for informational purposes only, and that the actual quantities of Waste to be
removed and disposed of hereunder will be determined by, among other things, the
actual availability and operating performance of the Facility as well as the
quality and other characteristics of the coal and limestone used at the
Facility.

     Section 5.3.  Method of Waste Disposal at Waste Disposal Site.

          (a) Waste Disposal Site. With respect to the Waste Disposal Site,
Anker represents that (i) directly or indirectly through affiliates or other
subcontractors, it has the right to dispose of Waste as contemplated herein at
the Waste Disposal Site; (ii) directly or indirectly through affiliates or other
subcontractors, Anker has all necessary rights of access to the Waste Disposal
Site to allow it to dispose of the Waste to the extent and in the manner and
quantities contemplated herein, (iii) directly or indirectly through affiliates
or other subcontractors, Anker is in full compliance with any and all Applicable
Laws and has all necessary Permits pertaining to the provision of Waste disposal
services as contemplated herein, (iv) no materials or substances have been
released or deposited at or on the Waste Disposal Site which may in any manner
constitute or result in a violation of, or create any liability under, any
Applicable Law concerning any waste or materials and (v) Anker will take all
necessary steps to ensure that no such waste or material which may be in
violation of any Applicable Law or may result in any such liability shall in the
future be released or deposited at the Waste Disposal Site.

          (b) Assurances as to Arrangements and Site. Anker shall enter into
such arrangements as are necessary to ensure the timely, safe and lawful
transportation from Anker's siding to the Waste Disposal Site in accordance with
the schedules determined pursuant to Section 5.3(f) hereof. Such arrangements
must ensure full compliance with Applicable Laws governing transportation and
disposal of Waste. Within forty-five (45) days after the date hereof, Anker
shall provide ER&L with evidence of such arrangements, which evidence shall
demonstrate to ER&L's satisfaction that Anker will be able to dispose of the
Waste as required hereunder.

     In addition, if Applicable Laws and Permit rules are changed so as to
prohibit Anker from disposing of the Waste as provided herein, or if the
disposal of Waste otherwise cannot be made at the Waste Disposal Site in the
manner and quantities contemplated herein, the provisions of Section 5.6 hereof
shall apply.

          (c) Siding Construction. At or near a Waste Disposal Site, Anker will
design and submit to ER&L for its approval, which shall not be unreasonably
withheld, a Waste unloading facility. After the design and location are approved
by ER&L, Anker will provide necessary grading and construct the necessary
unloading facility, including, but not limited to, the unloading pit, machinery,
lighting, and safety features. ER&L will provide and install necessary siding
tracks and switch work. Carloads of Waste will be unloaded and the cars reloaded
with Coal pursuant to this Agreement at or near the Waste unloading site.

          (d) Construction Costs, Allocation and Limits. It is agreed, if
Anker's costs for the Waste Disposal Facility (the "Base Cost") exceed [*],(8)
the provisions of

- -----------

confidential treatment filed with the Securities and Exchange Commission (the
"Commission"). The omitted portions, marked by "[*]," have been filed separately
with the Commission.

   21

Section 6.2(b) shall apply, and if the Base Cost is projected to exceed [*],(9)
at Anker's option the Parties will use their best efforts to negotiate a
mutually satisfactory alternative agreement. Should the parties fail to reach
such an agreement, Anker may elect either to spend the additional amount
required or to terminate its Waste disposal services under this Agreement. The
Base Cost for the Waste Disposal Facility shall include, without limitation,
capital cost and the cost of engineering, design and testing, whether performed
internally or by employing the services of third parties, and whether incurred
before, on or after the date of this Agreement.

          (e) Cost Recovery. If ER&L fails to deliver substantially all the
Waste from the Waste Removal Point to Anker's rail siding serving the Waste
Disposal Site, Anker may terminate its Waste disposal services under this
Agreement and ER&L shall reimburse Anker for its costs in designing, acquiring,
constructing and testing the Waste Disposal Facility less the accumulated
depreciation on the Waste Disposal Facility as shown on the books of Anker and
its affiliates. The provisions of this Section 5.3(e) shall be in addition to an
other remedy provided to Anker hereunder or by Applicable Law; provided,
however, that Anker shall not be entitled to reimbursement pursuant to the
preceding sentence to the extent of its use of the Waste Disposal Facility.

          (f) Schedule; Additional Costs. By the twentieth (20th) day preceding
the start of each calendar quarter during the term of this Agreement, ER&L shall
provide Anker with an estimate of the amount of Waste to be removed and disposed
of during such quarter pursuant to this Agreement. In addition, on or before the
twenty- eighth (28th) day of each calendar month during the term of this
Agreement, ER&L shall advise Anker of the estimated amount of Waste to be
removed from the Facility during the next succeeding calendar month. Upon
receipt of such notice, Anker shall arrange for the disposal of said estimated
quantities, provided, however, that upon ER&L's request Anker shall use its best
efforts to accommodate changing Waste disposal requirements of ER&L. Anker shall
have no responsibility, whether for the payment of demurrage charges or
otherwise, for any delays prior to the actual or constructive placement of the
cars at Anker's rail siding serving the Waste Disposal Site, including any
delays in loading or unloading the barges or in loading the cars. ER&L shall
indemnify Anker from and against any and all loss or liability arising out of or
in connection with such delays.

     ER&L represents to Anker that the Waste to be handled can readily be dumped
from the rail cars using conventional means. If the carloads of Waste are not
free flowing so they can be unloaded through bottom dump hoppers with the aid of
a car shaker, ER&L will reimburse Anker for any reasonable, extra expense
incurred to unload, haul, handle and dispose of the Waste.

          (g) Weighing. The weight of each quantity of Waste to be disposed of
by Anker hereunder shall be determined as follows: If such Waste is transported
in part by barge, the weight shall be determined after the Waste is loaded in
rail cars by using, at

   22

ER&L's option, either the official railroad weights or weights taken from
certified scales at the rail loading facility in Baltimore. If such Waste is not
transported in part by barge, the weight shall be taken from certified rail
scales on which ER&L shall cause the Waste to be weighed in the rail cars. ER&L
shall promptly furnish all such weights to Anker. If requested by Anker, ER&L
shall arrange reasonable notice and adequate access so that Anker has a
reasonable opportunity to observe the weighing procedure.

          (h) Invoices. Seven (7) days after the unloading of each bargeload of
Pelletized Waste, Anker shall send an invoice to ER&L for the Waste disposal
services relating to such Waste. With respect to Waste disposal services for Dry
Waste and any other Waste not shipped by barge, Anker shall send an invoice to
ER&L seven (7) days after the unloading at the Waste Destination Point of each
rail car load of such Waste.

          (i) Non-Complying Disposals. If Anker shall fail to dispose of any
Waste received by it, and unless otherwise excused hereunder, Anker shall have
thirty (30) days from the date of such failure to cure such breach by disposing
of said Waste shipment.

     If Anker f ails to cure such breach after notice from ER&L, then ER&L shall
have the right to purchase temporary replacement Waste disposal services from
alternative sources, and Anker shall use its best efforts to assist ER&L in
finding and acquiring such replacement services. Anker shall reimburse ER&L,
within thirty (30) days of receipt from ER&L of an invoice documenting the
relevant costs, for the difference, if any, between (1) the sum of any fines or
penalties that ER&L incurs under any Applicable Laws or Permits or otherwise as
a result of such breach by Anker plus the costs incurred by ER&L in purchasing
said replacement services minus (2) the amounts that would otherwise be payable
by ER&L to Anker hereunder for the services so replaced (including any amounts
which would in turn be payable by Anker to ER&L, or would be credited to ER&L,
for transportation, handling, and ancillary services relating to the Waste
disposed of).

     Section 5.4. Title. Title to the Waste to be disposed of by Anker hereunder
shall pass from ER&L to Anker upon actual placement at the Waste Destination
Point of the rail cars carrying such Waste.

     Section 5.5. Waste Disposal Service Not Required If Coal Is Not Used. Anker
will not be obligated, but may at its option elect, to provide Waste disposal
service if ER&L is not purchasing Coal from Anker under this Agreement.

     Section 5.6. Alternate Waste Disposal. (a) If Anker's failure to dispose of
Waste is the result of a change of Applicable Law or Permit rule or other reason
beyond Anker's reasonable control or otherwise excused hereunder, such failure
will not be a breach of this Agreement. In the event that Applicable Laws or
Permit rules are changed so as to prohibit or render uneconomical the
disposition of the Waste by Anker as contemplated by Section 5.3 hereof, or if
for reasons beyond Anker's control the disposal of Waste otherwise cannot be
made at the Waste Disposal Site in the manner and quantities contemplated
herein, Anker may so notify ER&L and propose to provide an


   23

alternate Waste disposal service at an adjusted Purchase Price therefor. If the
parties are unable to agree on such alternate Waste disposal service and
adjusted Purchase Price, Anker may elect to terminate its Waste disposal
services under this Agreement.

          (b) At any time during the term of this Agreement, Anker may propose
to provide Waste Disposal services at a location other than a Waste Disposal
Site. ER&L shall not unreasonably withhold its consent to any such proposal, but
ER&L's consent may be conditioned on the consent of AES.

                                   ARTICLE VI

                             PURCHASE PRICE FOR COAL

                           AND WASTE DISPOSAL SERVICES

     Section 6.1. Coal.

          (a) Purchase Price. The Purchase Price per Ton for the Coal under this
Agreement shall be equal to the base amount set forth below next to the Pricing
District (as determined pursuant to Section 6.1(b) hereof) in which the Coal is
loaded on rail cars:



                  Base Amount of
                  Purchase Price          Pricing District(s)
                  ---------------         -------------------

                                      
                  [*](10)                 Cumberland-Piedmont East
                  [*](10)                 Cumberland-Piedmont West, Mountain
                  [*](10)                 Fairmont, Grafton, WV Northern
                  [*](10)                 Clarksburg, Belington
                  [*](10)                 Elk River North, Gauley North,
                                               Beech Mountain
                  [*](10)                 Elk River South, Gauley Middle
                  [*](10)                 Gauley South


together with the adjustments thereto made for inflation in accordance with
Section 6.3 hereof and such other adjustments as are provided herein.

          (b) Pricing Districts. For purposes of Section 6.1(a) hereof, the base
amount of the Purchase Price for each Ton of Coal shall be determined according
to the Pricing District in which such Coal is loaded on rail cars for shipment
to the Facility. Annex D hereto sets forth coal loading locations in each
Pricing District. Coal loaded from such locations shall be deemed loaded in the
Pricing District indicated in Annex D, without regard to changes in railroad
freight districts which may occur from time to time. The Pricing District for
Coal which is not loaded from a location listed in Annex D shall

- -----------
(10) Portions of this exhibit have been omitted pursuant to a request for
confidential treatment filed with the Securities and Exchange Commission (the
"Commission"). The omitted portions, marked by "[*]," have been filed separately
with the Commission.

   24

be determined as follows: If the Coal is loaded from a location which is
situated between two locations listed under the same Pricing District in Annex
D, it shall be deemed loaded in said Pricing District. If the Coal is loaded
from a location which is situated between locations listed under different
Pricing Districts in Annex D, the Parties shall agree as to which of said
Pricing Districts includes such location.

          (c) Adjustment for Content. The Purchase Price of Coal shall be
adjusted for the heat content, ash content, and sulphur content, determined on
the basis of the Lab's analysis referred to in Section 4.4 hereof, as follows:

          (i) BTU's - [*](11) a Ton increase for each BTU/lb. by which the BTU's
exceed [*].(11)

          (ii) ash - [*](11) a Ton decrease or increase for each [*](11) of a
percentage point by which the ash content exceeds or falls below [*].(11)

          (iii) sulphur

               (a)  An increase of [*](11) a ton for each [*](11) of a
                    percentage point by which the sulphur content falls below
                    [*].(11)

               (b)  A decrease of [*](11) a ton for each [*](11) of a percentage
                    point by which the sulphur content exceeds [*].(11)

The foregoing adjustment amounts shall be adjusted for inflation in accordance
with Section 6.3 hereof.

          (d) Adjustments for Non-Conformity with Specifications. The Purchase
Prices for Coal in each calendar month shall be reduced to reflect the extent,
if any, to which the actual specifications of the Coal deliveries purchased
hereunder during such month do not conform with the applicable Individual or
Monthly Specifications. The Parties shall in good faith negotiate such reduction
promptly after the end of any such month. Either Party may submit such dispute
to arbitration under Section 13.1 hereof. Such negotiations and arbitration, if
any, shall take into account (i) the benefit of any bargain accruing to each of
ER&L and Anker under this Agreement in light of market prices available on the
Base Date with respect to agreements with similar durations and (ii) the
relative significance or insignificance of any nonconformance compared to all
other factors taken into account in arriving at the Purchase Price. For purposes
of clarification the parties acknowledge that, for example, if Coal is delivered
with a sulphur content in excess of the applicable specifications so that ER&L
is required to purchase more Limestone and handle more Waste than originally
contemplated, the Purchase Price for such Coal shall be reduced so that such
additional service attributable to such nonconformance shall be for Anker's
account.

          (e) Adjustment for Government Imposition Increases. Anker has
determined that a portion of the Purchase Price for Coal is allocable to the
charges that will be made by Anker (with respect to the supply of Coal under
this Agreement) for reimbursement of costs specified in this Section 6.1(e) (the
"Reimbursable Costs"). The Reimbursable Costs are the costs due to the
government impositions described below. Anker has determined that as of the Base
Date, the Reimbursable Costs in the aggregate are fairly attributed to [*](12)
of the Purchase Price for Coal (the "Total Percentage"), and that each category
of government imposition set forth below is fairly attributed to the "Partial
Percentage" of said Purchase Price set forth below.

Reimbursable Costs Attributable                             Partial Percentage
to Government Imposition

1.   Federal Black Lung excise tax
     for surface mined coal: the greater
     of 4% of the applicable sales price
     or $.55 per Ton, and/or

     Federal Black Lung excise tax for
     deep mined coal: the greater of 4% of
     the applicable sales price or $1.10 per
     Ton                                                       [*](12)

2.   Federal Reclamation Deep Mine Fee:
     $.15 per Ton and/or

     Federal Reclamation Strip Mine Fee:
     $.35 per Ton and/or
     State reclamation tax: $.0l per Ton                       [*](12)

3.   State coal severance or B&O tax or
     sales tax:

     3.85% of the applicable sales price                       [*](12)
4.   State Black Lung tax: 1% of gross payroll                 [*](12)

              Total Percentage                                 [*](12)

     If after the Base Date any change in government imposition within any
category above causes a change in Reimbursable Costs of Anker, the Purchase
Price for Coal shall be adjusted as provided herein. As soon as is practicable,
the Reimbursable Cost shall be recomputed in the same manner (except as noted in
this sentence) used in calculating the [*](12) Total Percentage, to reflect any
such change of government imposition within the appropriate category; the
recomputation of Reimbursable Costs shall take into account changes in the ratio
between surface and deep mining assumed on the Base Date and

- -----------
(12) Portions of this exhibit have been omitted pursuant to a request for
confidential treatment filed with the Securities and Exchange Commission (the
"Commission"). The omitted portions, marked by "[*]," have been filed separately
with the Commission.


   26

actually and reasonably anticipated at the time of the recomputation. The
Partial Percentage for such category shall be adjusted to equal:

Recomputed Reimbursable                   Original
      Costs                     x         Partial
- -----------------------
Original Reimbursable                     Percentage
      Costs

The Partial Percentages (as adjusted) shall be added to determine adjusted Total
Percentage. The difference between the adjusted Total Percentage and [*](13) (or
any more recent adjusted Total Percentage) shall be the "Difference Percentage."
The Purchase Price for Coal shall be adjusted to reflect [*](13) of such
Difference Percentage. Such adjustment shall be effective as of the effective
date of the change in government imposition, and shall be payable retroactively
to such date. Payment shall be made promptly upon receipt of the invoice
therefor.

     Anker represents that the determinations included in this Section 6.1(e) as
of the Base Date and the information in the chart above are accurate and true or
based upon reasonable projections and assumptions. Any adjustments in the
Purchase Price for Coal pursuant to this Section 6.1(e) shall be made on the
basis of true, accurate and reasonably detailed and confirmed information.

     If any new government imposition, not included in the categories in the
foregoing chart, is introduced and is payable by Anker in order to perform this
Agreement, the Parties shall in good faith negotiate (a) the Purchase Price
adjustment, and the corresponding modifications in the Total Percentage and
Partial Percentages, necessary to reimburse Anker for such new government
imposition and (b) the portion of such adjustment, if any, which ER&L will
provide whether or not it obtains equivalent adjustments and modifications from
AES. Thereafter, ER&L shall promptly and diligently attempt to negotiate
equivalent adjustments and modifications with AES. The adjustments negotiated by
the Parties shall apply hereunder to the extent that AES agrees with ER&L to
make equivalent adjustments in the purchase price, total percentage and partial
percentages provided for in the AES Agreement. To the extent that AES does not
agree to equivalent adjustments and modifications, the Purchase Price hereunder
shall be adjusted by an amount equal to the sum of (a) the amount of the portion
of the Purchase Price adjustment negotiated by the Parties to reimburse Anker
for such new government imposition which ER&L agreed to provide, if any, plus
(b) an amount, not exceeding the balance of such negotiated Purchase Price
adjustment, equal to any reduction in the government impositions included in the
categories in the foregoing chart which occurred in conjunction with the
introduction of such new government imposition.

     Section 6.2. Waste.

          (a) Purchase Price. The Purchase Price per Ton of Waste for the Waste
disposal services under this Agreement shall be equal to

           [*](14) per Ton for Pelletized Waste
           [*](14) per Ton for Dry Waste

together with the adjustments thereto made for inflation in accordance with
Section 6.3 hereof and such other adjustments as are provided herein. The
provisions of section 5.1(d) hereof shall apply to the determination of the
Purchase Price under the circumstances specified in that section.

          (b) Adjustment for Surcharge. If Anker's Base Cost for the Waste
Disposal Facility, as determined pursuant to Section 5.3(d), exceeds [*],(14)
the Purchase Price per Ton of Waste shall be increased by a surcharge (the
"Surcharge Adjustment") . The amount of the Surcharge Adjustment shall be
[*](14) for each [*](14) or part thereof by which the Base Cost exceeds [*].(14)
Anker shall notify ER&L of the amount of the Base Cost, and shall by notice
correct such amount from time to time as necessary. Promptly following any such
notice of correction, the Surcharge Adjustment shall be recalculated; the future
Purchase Price shall be adjusted accordingly; and the difference between the
total amount theretofore paid on account of the Surcharge Adjustment, and the
total amount that would have been payable on the basis of the Base Cost as so
corrected, shall be paid or refunded, as the case may be, by the appropriate
Party. The Surcharge Adjustment shall apply to, and only to, the Purchase Price
for the first [*](14) Tons of Waste to be disposed of by Anker hereunder in each
year for a period of [*](14) commencing [*].(14) If fewer than [*](14) Tons of
Waste are to be disposed of by Anker in any such year, ER&L shall pay Anker,
promptly following the end of such year, an amount equal to the Surcharge
Adjustment multiplied by the difference between [*](14) and the number of Tons
of Waste to be disposed of by Anker in such year. In the event that this
Agreement, or Anker's Waste disposal services hereunder, shall be terminated
prior to the expiration of the [*](14) period during which the Surcharge
Adjustment applies, ER&L shall promptly pay to Anker the total amount that would
thereafter have been payable on account of the Surcharge Adjustment.

          (c) Adjustment for Government Imposition Increases. If Applicable Laws
and Permit rules are changed so as to make it more expensive for Anker to use
its Waste Disposal Site, the rates, Purchase Price per Ton of Waste and other
applicable payments, if any, provided herein shall be adjusted to reflect the
benefits and detriments resulting to Anker as a result of continuance and use of
the Waste Disposal Site and the additional expenses incurred, including
additional capital expenditures.

   28

          (d) Adjustment for Start-Up Waste Disposal. In view of the Parties'
determination that the characteristics of the Waste delivered to Anker in
calendar year 1990 have not conformed to the Parties' expectations, the Purchase
Price per Ton for the first [*](15) Tons of Waste to be disposed of by Anker
shall be adjusted to compensate Anker for its additional start-up costs in
handling and disposing of such Waste. The amount of such adjustment shall be
[*](51) per Ton. The aggregate amount of such adjustment shall be payable in a
one-time lump sum payment on the date of this Agreement.

     Section 6.3. Inflation Adjustment. The Purchase Prices for Coal and waste
disposal services referred to in Section 6.1 (a) and Section 6.2(a),
respectively, the adjustment amounts set forth in Section 6.1(c) hereof, the
adjustment amounts set forth in Section 3.3(c) hereof, and the price payable for
freeze protection set forth in Section 4.1(c)(2) hereof, during any calendar
year shall be adjusted by Anker as soon as is practicable after the beginning of
such calendar year to equal the product of (a) such amount times (b) the sum of
one (1) plus [*](15) of the percentage change in the GNP Deflator from the GNP
Deflator for the first quarter of 1986 (the "Base GNP Value") to the GNP
Deflator for the fourth quarter of the immediately preceding calendar year (the
"Adjustment Formula"). Such adjustments shall be applied to the Purchase Prices
for all Coal and Waste disposal services delivered in the then-current calendar
year, and shall be retroactively applied to any such deliveries made in such
current year prior to the calculation of such adjustment amounts. If the
difference of the payments already made by ER&L during such current calendar
year minus the adjusted payment determined from such retroactive application of
the Adjustment Formula is a negative number, that difference shall be paid by
ER&L to Anker; if the difference is a positive number, that difference shall be
paid by Anker to ER&L. Such payments shall be made promptly upon receipt of an
invoice therefor.

     Section 6.4. Freight Charges; Adjustments.

          (a) Transportation Arrangements. ER&L shall be responsible for making
all arrangements for the transportation of Coal and Waste, and shall instruct
the carriers to direct their invoices to ER&L as the shipper.

          (b) Freight. All freight costs shall be for the account of ER&L, and
the Purchase Prices include the full consideration payable by Anker to ER&L for
transportation services arranged for and rendered hereunder, other than charges
(including without limitation demurrage) incurred at Anker's request or as a
result of Anker's acts or omissions.

          (c) Reimbursement or Adjustment for Change in Tariffs.

     (i) Demurrage Changes. ER&L shall reimburse Anker for demurrage costs
incurred by Anker in connection with the performance of this Agreement as a
result of any change in railroad demurrage rates or rules, as follows:

          A. Demurrage Rates. The amount that ER&L shall, reimburse Anker for
     costs caused by a demurrage rate change shall be Anker's actual cost under
     such rate change minus the lesser of: (x) the carrier's published demurrage
     charges or (y) the tariff charge for demurrage provided in the Original
     Applicable Tariff as adjusted for inflation pursuant to the Adjustment
     Formula set forth in Section 6.3.

          B. Demurrage Rules. The amount that ER&L shall reimburse Anker for
     costs caused by a demurrage rule change shall be an amount equal to the
     difference between Anker's demurrage costs under such rule change and
     Anker's demurrage costs immediately prior to the rule change.

     (ii) Non-Demurrage Changes. Subject to the limitations provided in this
Section 6. 4 (c) (ii) , ER&L shall reimburse Anker for non-demurrage costs
incurred by Anker in connection with the performance of this Agreement as a
result of a Compelled Change. A "Compelled Change" means a change in Anker's
facility, plant or operations compelled by a published railroad rate or rule
change (other than a change in demurrage rates or rules which is subject to the
provisions of Section 6.4(c)(i) hereof) applicable to Anker and other shippers
who are reasonably similar to Anker or its affiliates named in Annexes B and C
hereto as to location, size, and line of business. When a rate or rule change
that will result in a Compelled Change is announced, Anker and ER&L shall confer
within fourteen (14) days after Anker notifies ER&L of the rate or rule change
to determine a mutually cost efficient manner to effect the Compelled Change.
ER&L shall reimburse Anker starting from the date Anker puts the Compelled
Change into service until the termination-of this Agreement or any extension
thereof as to the commodity (Coal or Waste) handled or served by the facility or
plant affected by the rate or rule change that resulted in the Compelled Change;
provided, however, that in no event shall ER&L be liable to reimburse Anker more
than [*](16) for any Compelled Change. Unless the parties otherwise agree,
reimbursement for any Compelled Change is to be amortized in equal monthly
payments over five consecutive years; however, if this Agreement terminates
prior to full amortization, then ER&L shall not be responsible to further
reimburse Anker after such termination date. In the event that the costs
incurred by Anker related partly to the performance of this Agreement and partly
to unrelated business of Anker, then ER&L's reimbursement obligation under this
Section 6.4 (c) (ii) shall be limited to the prorated share of Anker's costs
that related to the performance of this Agreement at the time Anker incurred
such costs.

     (iii) Disputes. Any dispute regarding any reimbursement or adjustment
covering demurrage or non-demurrage changes in tariffs may be referred to
arbitration pursuant to Article XIII hereof.

                                   ARTICLE VII

                               PAYMENT AND RECORDS

     Section 7.1. Billing. Anker shall deliver to ER&L invoices showing the
Purchase Price for the Coal and the Waste disposal services delivered by Anker
and for any cost incurred by Anker for the account of ER&L and any reimbursement
or adjustment payable to Anker as provided in Sections 4.3, 5.3(h) and 6.4
hereof. If ER&L disputes any portion of any statement submitted by Anker for
payment pursuant to this Section 7.1, ER&L shall pay the undisputed portion of
such statement in accordance with Section 7.2 hereof and the Parties shall
cooperate and use their best efforts to resolve the dispute as quickly as
possible. Any such dispute may be submitted for arbitration in accordance with
Article XIII hereof.

     Section 7.2. Payment. ER&L shall pay to Anker the payment due on the basis
of each statement provided to ER&L by Anker pursuant to Section 7.1 hereof.
Payment shall be made by wire transfer into Anker's account designated from time
to time by Anker by notice and shall be received by Anker no later than the
"Payment Due Date". "Payment Due Date" means the later of (1) the last day of
the month in which the Coal being invoiced was shipped or the Waste being
invoiced was unloaded from rail cars at the Waste Destination Point, as the case
may be, or (2) the f6urth business day following the date of Anker's invoice.
Any payment not so made (including disputed amounts withheld and later
determined to be payable pursuant to arbitration, settlement or otherwise) shall
be overdue and shall bear interest, at an annual rate equal to the Prime Rate
plus one percent (1%), from the Payment Due Date until the earlier of (A) the
date such payment is actually received by Anker and (B) the 15th day of the
month next succeeding the month in which the Coal being invoiced was shipped or
the Waste being invoiced was unloaded, and thereafter shall bear interest at
such aggregate rate plus an additional three percent (3%) until the date such
payment is actually received by Anker.

     Section 7.3. Records. Each Party shall keep and maintain complete and
accurate records and all other data required by each of them for the purposes of
proper administration of this Agreement. In addition, Anker shall keep and
maintain complete and accurate records with respect to Waste disposal services,
including the amounts- of Waste disposed and the location of such disposal.
Anker shall make such records available to ER&L or its designees or
representatives upon request, and shall provide ER&L with access to such
personnel, all as may be required by ER&L to determine whether all Waste
disposal services were provided in compliance with all Applicable Laws and
Permits. All such records shall be maintained by Anker for five (5) years after
the expiration of this Agreement. At the end of such period ER&L may, at its
option, obtain from Anker and keep and maintain such records, or copies thereof,
for such duration as ER&L deems appropriate. Either Party will have the right
from time to time,


   31

upon written notice to the other, to examine the records and data of the other
relating to this Agreement at any time during the period the records are
required to be maintained under this Section 7.3.

                                  ARTICLE VIII

                                  FORCE MAJEURE

     Section 8.1. Definition. "Force Majeure" shall mean any cause or causes
which wholly or partly prevent or delay the performance of obligations arising
under this Agreement and which are not reasonably within the control of the
non-performing Party, and shall include, without limitation, a change of
Applicable Laws or Permit rules adversely affecting Waste disposal service, an
act of God, nuclear emergency, explosion, fire, epidemic, landslide, lightning,
earthquake, flood or similar cataclysmic occurrence, an act of the public enemy,
war, blockade, insurrection, riot, civil disturbance, general industry-wide
strikes of the United Mine Workers Union affecting the States of Kentucky, Ohio,
Pennsylvania and West Virginia, restrictions or restraints imposed by law or by
rule, regulation or order of governmental authorities, whether Federal, State or
local, and any other cause beyond the reasonable control of the Party relying on
such cause to excuse its performance hereunder; provided, however, that none of
the following shall constitute Force Majeure: (i) lack of money, (ii) changes in
market conditions, (iii) unless the result of any of the events listed above,
failure of the Mines to produce Coal in such quantities or of such quality as
required under this Agreement, or (iv) unless the result of any of the events
listed above, unavailability of the Waste Disposal Site for disposal of Waste.

     Section 8.2. Burden of Proof. In the event that the Parties are unable in
good faith to agree that a Force Majeure event has occurred, the Parties shall
submit the dispute for arbitration pursuant to Article XIII hereof, and the
burden of proof as to whether an event of Force Majeure has occurred shall be
upon the Party claiming an event of Force Majeure.

     Section 8.3. Effect of Force Majeure. If either Party is rendered wholly or
partially unable to perform its obligations under this Agreement because of a
Force Majeure event, that Party shall be excused from whatever performance,
other than an obligation to pay money, is affected by the Force Majeure event to
the extent so affected, provided, that:

          A. The non-performing Party within five (5) business days after the
     occurrence of the inability to perform due to a Force Majeure event shall
     provide written notice to the other Party of the particulars of the
     occurrence including an estimation of its expected duration and probable
     impact on the performance of its obligations hereunder and shall continue
     to furnish timely regular reports with respect thereto during the period of
     Force Majeure, but provided that if a Party has actual notice of the
     occurrence and status of the condition of Force Majeure, the other Party
     shall not be required to give such notice;


   32

          B. the non-performing Party shall use its best efforts to continue to
     perform its obligations hereunder and to remedy its inability to so perform
     (but such requirement shall not be construed to obligate a Party to accede
     to the demands of labor); Anker shall, at a minimum, allocate all of its
     available Coal supply and reserves and its Waste disposal capabilities on a
     pro rata basis among only ER&L and those other customers with whom Anker
     had firm contracts as of the date the Force Majeure condition commenced (or
     renewals on substantially the same terms as said original contracts); and
     ER&L shall, at a minimum, cause CSXT to allocate all of its available
     transportation and handling facilities on a pro rata basis among only Anker
     and those other customers with whom CSXT has firm contracts as of the date
     the Force Majeure condition commenced; and the non-performing Party shall
     notify the other Party promptly (but in no event later than three (3) days
     after the event of Force Majeure) of the proposed allocation method;

          C. the non-performing Party shall provide the other Party with prompt
     notice of the cessation of the event of Force Majeure giving rise to the
     excuse from performance;

          D. no obligation of either Party that arose prior to the occurrence of
     the event of Force Majeure shall be excused as a result of such occurrence;

          E. if either Party is prevented for more than one hundred twenty (120)
     days during any twelve (12) month period during the term hereof from
     substantially fulfilling its obligations under this Agreement by an event
     of Force Majeure, the other Party may terminate this Agreement; provided,
     however, that ER&L may not terminate this Agreement pursuant to this
     paragraph if Anker is prevented from so fulfilling its obligations by an
     event of Force Majeure affecting CSXT or ER&L's arrangements for
     transportation of the Coal and Waste.

     Section 8.4. Extension of Term. The term of this Agreement shall, at a
Party's option, be extended for a period equal to the sum of all periods during
which the other Party is unable as a result of a-Force Majeure event to perform
as required hereunder.

                                   ARTICLE IX

                                 RIGHT TO VISIT

     Section 9.1. Right to Visit. Each Party grants to the other (including its
agents) the right to visit its facilities, from time to time, upon reasonable
notice and subject to the applicable rules and regulations of the facilities, in
order to witness and review operations related to this Agreement. If ER&L
determines under Section 3.4 hereof that the Coal deliveries have caused
operating problems, ER&L and Anker shall cooperate in arranging for Anker to
review the specific problem area.


   33

                                    ARTICLE X

                            EVENTS OF DEFAULT; REMEDY

     Section 10. 1. Event of Default. (a) An event of default ("Event of
Default") under this Agreement shall be deemed to exist upon the occurrence of
any one or more of the following events:

          (1) Failure by either Party to make payment of any amounts due the
     other Party under this Agreement, which failure continues for a period of
     fifteen (15) days after written notice of such nonpayment.

          (2) Anker's failures to deliver shipments of Coal to ER&L or to
     dispose of shipments of Waste as required hereunder (without curing such
     failure within fifteen (15) days after notice of such failure pursuant to
     Sections 4.6(c) or 5.3(i) hereof) number in the aggregate six (6) or more
     in any twelve (12) month period during the term of this Agreement. It is
     understood a failure to dispose of Waste shipments because of a change of
     Applicable Law or Permit rules or because such change substantially
     increases Anker's cost, will not be an Event of Default.

          (3) Anker fails to provide the assurances requested by ER&L pursuant
     to Sections 4. 1 (b) , 4. 6 (b) or 5. 3 (b) hereof within fifteen (15) days
     after notice of such failure.

          (4) Failure by either Party to perform fully any other material
     provision of this Agreement, and (i) such failure continues for a period of
     thirty (30) days after written notice of such nonperformance or (ii) if the
     nonperforming Party shall commence within such thirty (30) days and shall
     thereafter proceed with all due diligence to cure such failure, such
     failure is not cured within such longer period (not to exceed ninety (90)
     days) as shall be necessary for such Party to cure the same with all due
     diligence.

     Section 10.2. Remedy for Breach. Upon the occurrence and during the
continuance of an Event of Default hereunder, the Party not in default shall
have the right to terminate this Agreement, upon ten (10) days' written notice
and to pursue any other remedy given under this Agreement or now or hereafter
existing at law or in equity or otherwise. ER&L may not terminate this Agreement
in part without Anker's consent.

     Section 10.3. Specific Performance and Injunctive Relief. Each Party shall
be entitled to a decree compelling specific performance with respect to, and
shall be entitled, without the necessity of filing any bond, to the restraint by
injunctive relief of any actual or threatened breach of, any material obligation
of the other Party under this Agreement.

     Section 10. 4. Waiver. Waiver by either Party of any breach, or failure to
require strict performance of the terms and conditions of this Agreement at any
time, shall in no way affect, limit or waive such Party's right thereafter to
enforce and compel strict


   34

compliance with this Agreement and shall in no way be construed as a consent to
any continuing or subsequent breach or failure to perform in strict compliance
with this Agreement.

     Section 10. 5. No Consequential Damages. Notwithstanding anything herein to
the contrary, neither Party shall be liable for consequential damages by virtue
of its breach of any of its obligations hereunder.

                                   ARTICLE XI

                                    INSURANCE

     Section 11.1. Insurance. Commencing on the first date upon which any
service is to be provided by Anker hereunder, Anker shall, at its own expense,
acquire and maintain the following minimum coverages:

     (a) Comprehensive General Liability Insurance, including automobile
liability and contractual liability, insuring the indemnity obligations set
forth in this Agreement, with completed operations coverage, with limits of
$1,000,000 per occurrence applicable to loss of or damage to property.

     (b) Worker's Compensation Insurance including occupational Disease
Insurance in accordance with the laws of the states where the work is to be
performed, and Employer's Liability Insurance in the amount of $1,000,000 per
occurrence.

     In addition, all dollar amounts expressed in this Section 11.1 shall be
updated triennially based on then current market conditions.

     Section 11. 2. Coverage. The insurance policies acquired and maintained by
Anker pursuant to Section 11.1 hereof shall be endorsed naming ER&L as
additional insured with respect to any and all third party bodily injury and/or
property damage claims arising from Anker's performance of this Agreement and
shall require thirty (30) days' written notice to be given to ER&L of
cancellation and material change in any of the policies.

     It is understood such insurance will not cover ER&L employees or agents
except when the injury is incurred on property owned or controlled by Anker. It
is further understood such insurance will not cover ER&L employees or agents for
black lung claims, workmen's compensation claims and in the event the employee's
or agent's injury is solely caused by his own negligence.

     Section 11.3. Evidence of Coverage. Evidence of insurance for the coverage
specified herein shall be provided by Anker to ER&L prior to the In-Service
Date. During the remaining term of this Agreement, Anker, upon reasonable
request, shall furnish ER&L with certificates of insurance described in this
Article XI.


   35

     Section 11.4. Liability Notwithstanding Insurance Coverage. The insurance
coverages described in this Article XI shall be primary to any other coverage
available to ER&L and shall not be deemed to limit Anker's liability under this
Agreement.

                                   ARTICLE XII

                              COMPLIANCE WITH LAWS

     Section 12. 1. Compliance with Laws. Anker represents and warrants to ER&L
that directly or indirectly through affiliates or other subcontractors it has
all Permits (which are accurately described in Annex E attached hereto), and
during the term of this Agreement shall maintain all Permits, required under
Applicable Law to be held in connection with the Mines, the Waste Disposal Sits,
the mining of Coal and the disposal of Waste as contemplated by this Agreement,
and as otherwise required to perform its obligations hereunder. Anker shall
comply with all Applicable Laws and Permits in performing its obligations
hereunder and shall operate and maintain the Waste Disposal Site in accordance
with all Applicable Laws. Anker shall promptly notify ER&L of any material
actual or threatened loss, amendment or breach of any such Permit or any
material actual or threatened breach of any such Applicable Law.

     It is understood if Applicable Laws and Permit rules are changed, Anker
will use its best efforts to comply with such changes, but if the changes make
it impossible or unreasonably uneconomical for Anker to furnish Waste disposal
service, Anker will not be required to do so.

                                  ARTICLE XIII

                                   ARBITRATION

     Section 13.1. Arbitration. The Parties shall negotiate in good faith and
attempt to resolve any dispute which may develop under this Agreement; however,
if the Parties are unable to resolve a dispute hereunder, either Party may serve
upon the other a demand that such matter be arbitrated, in which case the same
shall be resolved by arbitration conducted in accordance with the rules of the
American Arbitration Association. In the event of such a dispute, the Parties
shall endeavor to appoint an arbitrator agreeable to both of them, who shall be
the sole arbitrator. In the event that the Parties are unable to agree upon an
arbitrator within twenty (20) days of the filing of a demand for arbitration by
the initiating Party, then either Party may request the American Arbitration
Association to appoint a member in good standing of such Association as the sole
arbitrator. Unless the Parties otherwise agree, the arbitration will be held in
Washington, D.C. The Parties will proceed with the arbitration expeditiously and
will conclude all proceedings thereunder, including any hearing, in order that a
decision may be rendered within one hundred twenty (120) days from the filing of
the demand for arbitration by the initiating Party. The award of the arbitrator
will be final and binding on both Parties and may be enforced in any court
having jurisdiction of the Party against which enforcement is sought. Each Party
shall bear its own expenses, including but not limited to counsel


   36

fees, except that all expenses of the arbitration shall be apportioned in the
award of the arbitrator based upon the respective merit of the positions of the
Parties. This Section 13.1 shall survive the termination or expiration of this
Agreement.

     Section 13.2. Price and Payment During Arbitration. Whenever a decision has
not been rendered within the 120-day period provided by Section 13.1 hereof in
an arbitration which relates to a Purchase Price increase proposed by Anker or
to a disputed payment withheld by ER&L, ER&L shall, upon the expiration of such
120-day period, commence paying to Anker such proposed Purchase Price or pay to
Anker such withheld payment, as the case may be. Upon the rendering of the
arbitral decision, all overpayments shall be refunded and all underpayments
shall be paid, with interest thereon in each case at an annual rate equal to the
Prime Rate plus one percent (1%) except where a different interest rate is
applicable pursuant to Section 7.2 hereof.

                                   ARTICLE XIV

                                 INDEMNIFICATION

     Section 14.1  Indemnification

     (a) General. Each Party shall indemnify and hold the other Party and its
successors and assigns harmless from and against all damages, losses or expenses
suffered or paid as a result of any and all claims, demands, suits, penalties,
causes of action, proceedings, judgments, administrative and judicial orders and
liabilities (including reasonable counsel fees incurred in any litigation or
otherwise) assessed, incurred or sustained by or against such other Party and
its successors and assigns with respect to or arising out of any breach by the
indemnifying Party or its warranties, representations, covenants or agreements
hereunder.

     (b) Environmental. Anker shall indemnify and hold ER&L and its successors
and assigns harmless from and against all damages, losses or expenses suffered
or paid as a result of any and all claims, demands, suits, penalties, causes of
action, proceedings, judgments, administrative and judicial orders and
liabilities (including reasonable counsel and consultant fees incurred in any
litigation or enforcement efforts) assessed, incurred or sustained by or against
ER&L and its successors and assigns under any statute, regulation, ordinance or
common law theory and arising out of any matter relating to environmental
protection aspects of the transportation from Anker's rail siding to the Waste
Disposal Site and disposal of the Waste by Anker and its employees, contractors
and agents, unless such damages, losses or expenses arose solely because of a
change in Applicable Laws or Permit rules, in which event no indemnity will be
due from Anker to ER&L.

     Section 14.2. Notice and Legal Defense. Promptly after receipt by a Party
of any claim or notice of the commencement of any action, administrative or
legal proceedings, or investigation as to which the indemnity provided for in
Section 14.1 hereof, or an indemnity provided elsewhere in this Agreement
(including without limitation Sections


   37

4.1, 4.2 (b) , 5. 1 (b) and 5.3 (f) hereof) , may apply, the indemnified Party
shall notify the indemnifying Party in writing of such fact. The indemnifying
Party shall assume the defense thereof with counsel designated by such Party and
satisfactory to the indemnified Party; provided, however, that if the defendants
in any such action include both the indemnified Party and the indemnifying Party
and the Parties conclude that there may be legal defenses available to
indemnified Party which are different from or additional to, or inconsistent
with, those available to the indemnifying Party, the indemnified Party shall
have the right to select separate counsel to participate in the defense of such
action on behalf of such indemnified Party, at the indemnifying Party's expense.

     Section 14.3. Failure to Defend Action. Should a Party be entitled to
indemnification under Section 14.1 hereof as a result of a claim by a third
party, and the indemnifying Party fails to assume the defense of such claim, the
indemnified Party shall at the expense of the indemnifying Party contest (or,
with the prior written consent of such indemnifying Party, settle) such claim,
provided that no such contest need be made and settlement or full payment of any
such claim may be made without consent of the indemnifying Party (with such
indemnifying Party remaining obligated to indemnify the indemnified Party
hereunder) if, in the written opinion of the indemnified Party's counsel, such
claim is meritorious.

     Section 14.4. Indemnification Amount. In the event that a Party is
obligated to indemnify the other Party hereunder, the amount owing to the
indemnified Party will be the amount of such Party's actual out-of-pocket loss
net of (i) any insurance or other recovery and (ii) any net reduction of taxes
realized by the indemnified person as a result of such loss and any recovery
(whether such recovery is the indemnity payment made under this Article XIV or
insurance proceeds).

                                   ARTICLE XV

                               NOTICE AND SERVICE

last nine (9) of such


   38

eighteen (18) hours fall on a Saturday, Sunday or federal legal holiday, then at
9 a.m. the following business day.

          (iii) If a notice is served by fax, it shall be deemed given and
received when it is transmitted, provided, however, that notice served by fax
shall only be effective if the sending party first telephones the notified party
to advise that the notice is being sent.

          (c) Notices shall be sent to the Parties at the following addresses:

     Section 16.1 Assignment by Parties.

     (a) Except as specified below, the rights and obligations of the Parties to

written consent of the other Party which consent shall not be unreasonably

     (b) Either Party shall have the right, without the consent of the other

Party.


   39

and the respective rights and obligations hereunder of Anker and ER&L shall be
binding upon, and inure to the benefit of, their respective permitted successors
and assigns.

     Section 16.3. Undertaking of CSXT. In consideration for Anker's entering
into this Agreement, ER&L shall arrange for CSXT, which owns indirectly all of
the issued and outstanding shares of ER&L, to deliver to Anker, effective as of
the date of this Agreement, an agreement to be responsible for all of the
obligations of ER&L hereunder and certain other obligations, substantially in
the form of Annex F hereto.

                                  ARTICLE XVII

     Section 17. 1. Independent Contractor. Each Party will at all times act as
and be deemed to be an independent contractor for all purposes of this Agreement
and will not act as nor be deemed to be an employee or agent of the other Party.

     Section 17.2. Confidentiality. Anker and ER&L shall retain in confidence
the commercial terms of this Agreement and any information obtained as a result
of negotiation and performance of this Agreement which either Party identifies
to the other as being proprietary in nature, except that the Parties may
disclose such information to any parties providing financing or to any party
controlling, controlled by, or under common control with such Party. It is
understood, however, that such information may be disclosed when requested by a

     Section 17.4. Choice of Law. This Agreement shall be governed by and

     Section 17.5. Severability and Renegotiation. Should any provision of this
Agreement for any reason be declared invalid or unenforceable by final and
unappealable order of any court or regulatory body having jurisdiction
thereover, such decision shall not affect the validity of the remaining
portions, which remaining portions shall remain in force and effect as if this
Agreement had been executed with the invalid portion thereof eliminated. In the
event any such provision of this Agreement is so declared invalid, the Parties
shall promptly renegotiate in good faith new provisions to eliminate such
invalidity and to restore this Agreement as near as possible to its original
intent and effect.

     Section 17. 6. Other Agreements. This Agreement, together with the
agreement of CSXT referred to in Section 16.3 hereof and that certain Agent and
Substitution Agreement by and among Anker, CSXT and ER&L effective November 30,
1990 (the


   40

"Agent and Substitution Agreement"), supersede any and all oral or written
agreements and understandings heretofore made relating to the subject matters
herein and therein and constitute the entire agreement and understanding of the
Parties relating to the subject matters herein and therein. Without limiting the
effect of the preceding sentence, it is specifically agreed that as of the date
hereof, this Agreement amends in its entirety the CSXT-Anker Agreement and that,
upon the execution and delivery of this Agreement, the agreement of CSXT
referred to in Section 16.3 hereof, and the AES-ER&L Agreement, the CSXT-Anker
Agreement shall be terminated and replaced by this Agreement, all except for the
provisions of the Amendatory Agreement to the CSXT-Anker Agreement dated as of
June 21, 1989, which Amendatory Agreement remains in full force and effect as a
valid and subsisting Agreement between Anker and CSXT. This Agreement is the New
Anker Agreement referred to in the Agent and Substitution Agreement.

     Section 17.7. Transitional Provisions. In furtherance of Section 17.6
hereof and of the Agent and Substitution Agreement, the following provisions
shall apply to this Agreement.

            (a) Capacity of ER&L. ER&L has entered into this Agreement and shall
perform this Agreement in its capacity as agent for CSXT while the AES-CSXT
Agreement remains in effect. ER&L has entered into this Agreement and shall
perform this Agreement as principal upon and after the date on which the
AES-ER&L Agreement becomes effective.

            (b) Historical Provisions. Certain provisions of this Agreement
relate to matters which transpired prior to the date of this Agreement, but
which were performed pursuant to corresponding provisions of the CSXT-Anker
Agreement. Such provisions are included herein for purposes of historical
reference and of Section 17.7(c) hereof.

            (c) Ratification. The Parties hereby ratify and adopt for purposes
of this Agreement all notices, approvals, consents and other actions taken by or
between CSXT and Anker pursuant to corresponding provisions of the CSXT-Anker
Agreement, including, without limitation, any changes of Individual
Specifications as contemplated by Section 3.3 (c) hereof, any adjustments to
specifications as contemplated by Section 3.4 hereof, any approvals of coal
sources as contemplated by Section 3.5 hereof, any scheduling information and
arrangements as contemplated by Sections 4.2 and 5.3 (f) hereof, the selection
of the Lab as contemplated by Section 4.4 hereof, and any price adjustments as
contemplated by Article VI hereof.

     Section 17. 8. Change of Carrier. This Agreement contemplates that ER&L
will arrange for transportation of Coal via CSXT. Nothing in this Agreement,
however, shall be construed to prevent ER&L from arranging for transportation
via any other carrier, subject to the Parties' agreement on suitable terms
corresponding to the provisions hereof which relate to transportation via CSXT.

titles and similar items are provided for the purpose of reference and
