<PAGE>


      may be coordinated with other barge deliveries to the Ghent Generating 
      Station.

      SECTION III. SOURCE AND SHIPMENT OF, AND TITLE TO, COAL.

      1. The primary source of coal to supply the requirements of this 
Agreement shall be the Shoemaker Mine and the McElroy Mine in Marshall 
County, West Virginia. As necessary to comply with the quality requirements 
of this Agreement, Seller may blend with coal from such primary sources, coal 
from Seller's Dilworth, Mahoning Valley, Bailey and/or Enlow Fork Mines. 
Seller may substitute comparable quality coal from other reserves that Seller 
controls now or in the future, so long as such coal (A) is delivered to KU at 
no greater delivered cost per million BTU including taxes, (B) is of a 
quality and in conformity with the Specifications set forth in Section IV and 
(C) prior written approval for such substitution has been obtained from KU.

      2. Seller represents and warrants that the coal reserves now controlled 
by Seller and Seller's production capacity are sufficient to satisfy all the 
requirements of this Agreement. It is understood that some of the production 
may be sold to purchasers other than KU; provided, however, that Seller 
shall, at all times while this Agreement remains in effect, maintain 
sufficient coal reserves and production capacity for Seller's full 
performance of its obligations hereunder.

      3. Seller shall prepare and load the coal into barges provided by KU's 
barge carrier. Seller shall deliver the coal to 

                                     -3-

      (c) KU shall have the right to classify as rejectable any barge of coal
      which, when sampled and analyzed in accordance with the provisions of
      Section VIII, fails to meet the Specifications set out in Paragraph 2(b)
      of this Section IV. If KU does reject coal failing to meet such
      Specifications, Seller shall forthwith arrange for coal to be removed from
      the barge or shipped to another purchaser at Seller's expense, including
      but not limited to sampling and barge demurrage. If all coal received
      hereunder by KU for three consecutive barges is classified by KU as
      rejectable coal, or if KU has other reasonable grounds to anticipate that

                                     -5-
<PAGE>


      further shipments will be of rejectable coal, KU shall have the option of
      stopping further shipments of coal by Seller until such time as Seller
      furnishes to KU reasonable assurance that the quality of coal to be
      shipped hereunder will meet the Specifications in Paragraph 2(a). In lieu
      of rejecting the coal, KU may at its option purchase the rejected coal on
      a "distress" basis mutually agreed upon.

      (d) If 20-percent or more of monthly ratable shipments do not meet the
      Specifications in Paragraph 2(a), KU shall also have the option of
      stopping shipments until Seller furnishes reasonable assurance that the
      quality of coal shipped hereunder meets the Specifications in Paragraph
      2(a).

      (e)   SELLER HEREBY DISCLAIMS, AND BUYER HEREBY WAIVES, ANY AND ALL
      IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR
      PURPOSE.

      SECTION V. PRICES OF COAL. Prices hereafter specified are to be paid by KU
to Seller for coal delivered and accepted hereunder and include any barge
fleeting or switching charges. Such prices shall not be increased before April
1, 1995, by increases in Seller's cost of Reclamation, Royalty expenses,
Severance Taxes, any other applicable Taxes, or any other costs included in the
Price f.o.b. Barge. After April 1, 1995, such prices shall be subject only to
the Adjustments herein specified.

               April 1, 1995 through                        $18.00
                   March 31, 1996
               April 1, 1996 through                        $18.40
                   March 31, 1997
               April 1, 1997 through                        $18.75
                   March 31, 1998

      Such prices shall remain fixed during each contract year.

      2. The above price shall be subject to adjustment only in the event of 
the enactment or change of any applicable federal or state statutes, 
regulations, or other governmental impositions occurring after April 1, 1995, 
which cause Seller's cost for providing coal to KU under this Agreement to 
increase or decrease. Seller shall promptly notify KU of any such changes and 
supply sufficient documentation for KU to verify any such changes. Such 
adjustments shall be made effective on the first day of the calendar month 
following the effective date of any change, (except when such change is 
effective on the first day of the month in which case the adjustment shall be 
made as of such date).

<PAGE>


      SECTION VI.  CALORIFIC, ASH AND MOISTURE ADJUSTMENTS.

      1. As soon as practicable after the end of each month, KU shall 
determine and report to Seller the weighted average calorific value, in BTU 
per pound, the weighted average ash content, in percent, and weighted average 
moisture content, in percent, from the weights of such coal determined as 
provided in Section VII and from analyses thereof made as provided in Section 
VIII. The debits or credits resulting from the calorific, ash and moisture 
adjustments described in the following paragraphs (2), (3), (4), and (5) will 
be made by the end of the following month.

      2. CALORIFIC ADJUSTMENT. Such weighted average calorific value shall be
used in adjusting the price of coal in the following manner. The f.o.b. Barge
Price then in effect, specified and determined as provided in Section V, but
before any Ash or Moisture Adjustment provided for hereafter in this Section VI,
shall be adjusted to reflect variation from 12,000 BTU per pound in such
weighted average calorific value of the coal received, in arriving at the price
(exclusive of any Ash or Moisture Adjustment) to be paid by KU to Seller for
such coal, in accordance with the following formula (assuming, for purposes of
illustration, an f.o.b. Barge Price, prior to the Calorific Adjustment, of
$18.00):

  ACTUAL   BTU/LB.   -   12,000   x   $18.00   =   Premium/Penalty    Per   Ton
  -----------------------------
             12,000

      3. ASH ADJUSTMENT.

(a) If the monthly weighted average percent of ash for all

                                     -8-
<PAGE>


receipt(s) received is less than 8.00%, the upward price adjustment shall be 
$0.20/ton per percent with a base of 8.00%, I.E., ($0.20/ton x (8.00% - 
monthly weighted ash %) = upward price adjustment).

Example:  Monthly  weighted  average ash analysis is 5.80%,
      $0.20/ton x (8.00% - 5.80%) = $0.44/ton is the upward price adjustment.

(b) If the monthly weighted average percent of ash is in excess of 11.00% and is
less than or equal to 12.00%, the downward price adjustment shall be $0.20/ton
per percent with a base of 11.00%, I.E., ($0.20/ton x (monthly weighted ash % -
11.00%) = downward price adjustment).

Example:   Monthly  weighted  average  ash  analysis  is  11.50%,
  $0.20/ton  x (11.50% - 11.00%) = $0.10/ton is the downward price adjustment.

(c) If the monthly weighted average percent of ash is greater than 12.00% and is
less than or equal to 13.00%, the downward price adjustment shall be $0.40/ton
per percent with a base of 11.00% I.E., ($0.40/ton x (monthly weighted ash % -
11.00%) = downward price adjustment).

Example:   Monthly  weighted  average  ash  analysis  is  12.50%,  $0.40/ton  x
(12.50% - 11.00%) = $0.60/ton is the downward price adjustment.

(d) If the monthly weighted average percent of ash is greater than 13.00%, the
downward price adjustment shall be $0.70/ton per 

                                     -9-
<PAGE>


percent with a basis of 11.00%, I.E., ($0.70/ton x (monthly weighted ash % - 
11.00%) = downward price adjustment).

Example:   Monthly  weighted  average  ash  analysis  is  13.50%,  $0.70/ton  x
(13.50% - 11.00%) = $1.75/ton is the downward price adjustment.

      4.    MOISTURE ADJUSTMENT.

(a) If the monthly weighted average percent of moisture is in excess of 10.00%
and is less than or equal to 11.00%, the downward price adjustment shall be
$0.04/ton per percent with a base of 10.00%, I.E., ($0.04/ton x (monthly
weighted moisture % - 10.00%) = downward price adjustment). Example: Monthly
weighted average moisture analysis is 10.50%, $0.04/ton x (10.50% - 10.00%) =
$0.02/ton is the downward price adjustment.

(b) If the monthly weighted average percent of moisture is greater than 11.00%
and is less than or equal to 12.00%, the downward price adjustment shall be
$0.08/ton per percent with a base of 10.00%, I.E., ($0.08/ton x (monthly
weighted moisture % - 10.00%) = downward price adjustment). Example: Monthly
weighted average moisture analysis is 11.50%, $0.08/ton x (11.50% - 10.00%) =
$0.12/ton is the downward price adjustment.

(c) If the monthly weighted average percent of moisture is greater than 12.00%,
the downward price adjustment shall be $0.12/ton per percent with a base of
10.00%, I.E., ($0.12/ton x 

                                     -10-
<PAGE>


(monthly weighted moisture % - 10.00%) = downward price adjustment).

Example:  Monthly  weighted average  moisture  analysis is 12.50%,  $0.12/ton x
(12.50% - 10.00%) = $0.30/ton is the downward price adjustment.

      5. COMBINATION OF ADJUSTMENTS. The 11,700 BTU per pound Minimum Calorific
Value, 13.00% Maximum Ash, and 10.00% Maximum Moisture. Specifications in
Paragraph 2(b) of Section IV shall apply in the determination of coal
rejectability; but if KU receives and burns coal not meeting Specifications in
Paragraph 2(a) of Section IV, the actual BTU per pound, actual Ash content and
actual Moisture content of the coal shall be used in computation of the
Adjustments provided for in this Section VI. When the Calorific Adjustment, Ash
Adjustment, and Moisture Adjustment have been independently made as above
provided, the results shall be combined, and the final adjustment to the price
payable for such coal is so determined.

      SECTION VII. WEIGHT DETERMINATIONS. The determinations of the weight of
the coal, for purposes of payment, shall be made with KU's belt scales at Ghent.
KU will provide to Seller by fax or other expeditious means, the barge weights,
as they become available. Said scales shall be inspected and certified in
accordance with the appropriate provisions of the laws of Kentucky. Seller shall
have the right to inspect at reasonable times and witness the certification of
said scales. If a 

                                     -11-
<PAGE>


discrepancy is found as a result of said inspection or certification, same 
shall be resolved by mutual consent.

      SECTION VIII.  SAMPLING AND ANALYSIS.

      1. The Seller has sole responsibility for quality control of the coal and
shall forward its loading quality to KU as soon after barge loading as
practicable. KU will, for purposes of payment, take a representative sample at
Ghent. Samples taken by KU, for purposes of payment, shall be taken in
accordance with KU's approved procedures of sampling. Each barge shall be
sampled and analyzed by KU. The analyses shall be performed in KU's laboratory
in accordance with KU's approved methods. Each barge sample shall be analyzed
for the as-received average moisture, ash, BTU and sulfur content. KU will
furnish Seller revisions of KU's approved sampling procedures.

      2. KU shall compute the as-received weighted average moisture, ash, BTU
and sulfur content for all coal received during each calendar month. Such
calculations and payment of any premium/penalty adjustments will be delivered to
Seller before the end of the following month. The values so determined shall be
binding upon the parties unless and until it is established, by one or more
independent laboratories using the referee sample as designated in Section
VIII.3., that such analyses or calculations have been erroneous.

      3. Prior to testing, each gross sample shall be divided into four equal
portions and used as follows: one shall be 

                                     -12-
<PAGE>


analyzed to determine the quality of the coal; one shall be available for 
Seller (Seller sample); one shall be retained by KU, as the referee sample 
for a period of 30 days. If requested by either party, such retained referee 
sample will be sent to the location mutually agreed to for testing. All 
testing of any such sample by third parties shall be at requester's expense 
unless the results differ by more than the applicable ASTM reproducibility 
standards, in such case, KU will pay for testing. If the independent 
laboratory results differ by more than the applicable ASTM reproducibility, 
independent laboratory results will govern.

      4. KU shall provide to Seller, by mail or more expedient methods as
required, the as-received weighted average moisture, ash, BTU and sulfur content
of each barge received.

      5. Seller shall have the right to inspect, observe the operation of any
sampling device or appurtenance thereto, sample crusher, reducer, sample
container, laboratory equipment or procedure of KU. A proven deficiency in KU's
sampling or testing procedures or facilities discovered by Seller shall be
brought to KU's attention, and KU shall take any needed corrective action.

      SECTION IX. BILLING AND PAYMENT. Seller shall invoice KU for coal in each
shipment. Such invoices shall be itemized to the extent required by KU, and
shall be paid within 15 days after receipt of coal and receipt of invoice by KU.

                                     -13-
<PAGE>


      SECTION X. RECORDS AND AUDITS. Seller shall maintain accurate and 
complete books of account and records regarding coal delivered hereunder. KU, 
or independent consultants or firms designated by KU, shall have the right at 
all times to observe and inspect Seller's operations, and at any reasonable 
time or times to examine and audit all pertinent books of account and records 
of Seller for the purpose of verifying transactions and matters hereunder. If 
any such examination or audit discloses that an error has occurred and 
resulted in an overpayment or underpayment hereunder, the amount thereof 
shall be established and promptly paid, by the owing party, to the party 
owed. This provision shall survive the termination or expiration of this 
Agreement.

      SECTION XI.   COMPLIANCE WITH LAWS, REGULATIONS, POLICIES AND 
RESTRICTIONS.

      1. The parties recognize that, during the continuance of this Agreement,
legislative or regulatory bodies or the courts may adopt laws, regulations,
policies and/or restrictions which will make it impossible or commercially
impractical for Seller to continue delivery hereunder. If as a result of the
adoption of such laws, regulations, policies or restrictions, or change in
interpretation or enforcement thereof Seller decides that it will be impossible,
or economically or otherwise impracticable for Seller to continue delivery
hereunder, Seller shall so notify KU, and thereupon Seller and KU shall promptly
consider whether corrective actions can be taken in the mining and preparation
of

                                     -14-
<PAGE>


the coal at Seller's mine and/or in the handling and utilization of the coal 
at KU's Ghent Unit 1; and if in Seller's judgment such actions will not, 
without unreasonable expense to Seller, make it possible and practical for 
Seller to continue to deliver coal hereunder and without violating any 
applicable law, regulation, policy or restriction, Seller shall have the 
right, upon notice to KU, to terminate this Agreement without further 
obligation hereunder on the part of either party; provided, however, that if 
the impracticality of Seller's continuing to deliver coal hereunder is only 
on economical grounds, KU may, at its option, prevent such termination by 
agreeing to reimburse Seller for such expense to the extent that Seller deems 
such expense to be unreasonable.

      2. The parties also recognize that, during the continuance of this
Agreement, legislative or regulatory bodies or the courts may adopt laws,
regulations, policies and/or restrictions or change in interpretation or
enforcement thereof which will make it impossible or commercially impracticable
for KU to utilize in Ghent 1 Unit this or like kind and quality coal which
thereafter would be delivered hereunder. If as a result of the adoption of such
laws, regulations, policies or restrictions, KU decides that it will be
impossible or economically or otherwise impracticable for KU to utilize in KU's
Ghent Unit 1 coal which would be delivered hereunder, KU shall so notify Seller,
and thereupon KU and Seller shall promptly consider whether corrective actions
can 

                                     -15-
<PAGE>


be taken in the mining and preparation of the coal at the mine and/or in the 
handling and utilization of the coal at KU's said Station; and if in KU's 
judgment such actions will not, without unreasonable expense to KU, make it 
possible and practical for KU to so utilize coal which thereafter would be 
delivered hereunder and without violating any applicable law, regulation, 
policy or order, KU shall have the right, upon notice to Seller, to terminate 
this Agreement without further obligation hereunder on the part of either 
party; provided, however, that, if the impracticality of KU's utilizing the 
coal is only on economical grounds, Seller may, at its option, prevent such 
termination by agreeing to reimburse KU for such expense to the extent that 
KU deems such expense to be unreasonable.

      SECTION XII.  FORCE MAJEURES.

      1. DEFINITION. The term "force majeure" as used herein shall mean any and
all causes reasonably beyond the control of the party failing to perform, such
as but not limited to acts of God, acts of the public enemy, insurrections,
riots, labor disputes, government closures, boycotts, labor and material
shortages, fires, explosions, floods, breakdowns or outages (including scheduled
outages for maintenance or repairs) of or damage to plants, equipment or
facilities, interruptions to power supplies or transportation, embargoes, and
acts of military or civil authorities, which wholly or partly prevent the
mining, processing, loading and/or delivering of the coal by Seller, or 

                                     -16-
<PAGE>


the receiving, accepting and/or utilizing of the coal by KU. As used in the 
preceding sentence, the phrase "prevent the receiving or accepting" (of the 
coal by KU) shall include, but not be limited to, breakdowns or outages of 
the material handling systems at the Ghent Station. The parties recognize 
that coal purchased by KU hereunder is intended by it for use in its Ghent 
Unit 1. No breakdown or outage of any KU generating unit other than Ghent 
Unit 1 shall constitute a force majeure hereunder; nor shall any asserted 
ability of KU to use coal in any generating unit other than Ghent Unit 1 be 
deemed to negate or eliminate a force majeure hereunder. As used in this 
Paragraph, "scheduled outages for maintenance or repairs" includes, but is 
not limited to, outages determined by KU to be necessary for warranty 
inspections, periodic major overhauls, identification and/or correction of 
causes of unsatisfactory performance including but not limited to failure to 
meet environmental requirements, and/or performance of maintenance or repairs 
reasonably believed to be necessary to the avoidance of involuntary or forced 
outages. The outages do not include outages for normal maintenance performed 
on an annual basis. For purposes of this Section XII, any force majeure 
events which wholly or partly prevent the mining, processing, loading and/or 
delivering of the coal by Seller from the Shoemaker and/or McElroy mine(s) 
shall be deemed to equally prevent the mining, processing, loading and/or 
delivering of the coal by Seller from all other sources listed in Section 
III.1.
                                     -17-
<PAGE>


 Each party shall promptly notify the other party following commencement of a 
force majeure.

      2. EFFECT HEREUNDER--GENERAL. If because of a force majeure either party
is unable to carry out any of its obligations under this Agreement (other than
the obligation to pay money in connection with performance of the Agreement),
and if such party shall promptly give to the other party written notice of such
force majeure, then the obligations of the party giving such notice and the
corresponding obligations of the other party shall be suspended to the extent
made necessary by such force majeure and during its continuance; provided,
however, that the party giving such notice shall act promptly in reasonable
manner to eliminate such force majeure. Either party shall have the right to
elect to suspend the production, delivery, receipt, acceptance and/or sale or
purchase of coal, as the case may be, for the period of time during which such
force majeure exists; and, in the event of a force majeure declared by Seller,
KU, if it so elects, shall have the right during such period to purchase coal
from other sources, and, in the event of a force majeure declared by KU, Seller,
if it so elects, shall have the right during such period to sell coal to others.
Any deficiencies in deliveries of coal hereunder caused by force majeures shall
not be made up except by mutual consent; but if Seller for any reason other than
a KU force majeure fails to deliver coal to KU pursuant to normal established
shipment schedules but does not 

                                     -18-
<PAGE>


notify KU of the occurrence of a force majeure, KU shall have the right to 
require, but shall not be obligated to accept, make-up tonnages or deliveries 
of tonnages so lost, at the price in effect when lost.

      3. TERMINATION FOR PROTRACTED FORCE MAJEURE(S). If (A) a force majeure
occurs, (B) the obligations of the parties are suspended pursuant to provisions
of this Section XII, (C) such condition (alone or extended by other force
majeures) continues so that the obligations of the parties remain suspended for
a period of six months, and (D) at the end of such six months or at any time
thereafter during the continuance of the force majeure(s) the party other than
the party suffering the force majeure(s), in the exercise of reasonable
judgment, concludes that there is no likelihood of discontinuance in the
immediate future of the force majeure(s) or the resulting suspension of the
obligations of the parties, then such party may terminate this Agreement without
liability to the party suffering the force majeure(s) by giving to such party
sixty days written notice of intention to terminate, unless the force majeure(s)
are discontinued and the obligations are restored within such sixty days.

      SECTION XIII.  WAIVERS AND REMEDIES.

      1. The failure of either party to insist in any one or more instances upon
strict performance of any provision of this Agreement by the other party, or to
take advantage of any of its 

                                     -19-
<PAGE>

rights hereunder, shall not be construed as a waiver by it of any such rights 
with respect to any subsequent non-performance of such provision or other 
matter hereunder; but the provision shall retain its effectiveness and 
enforceability, and the rights of the parties shall continue and remain in 
full force and effect.

      2. If, at the time a party takes action hereunder requested or demanded 
by the other party, the party taking the action gives written notice that it 
is doing so under protest and without agreement as to the appropriateness of 
the action, then the taking of the action, even if thereafter repeated 
without further notice, shall not give rise to application of the principles 
of contemporaneous construction by the parties.

      3. Each remedy specifically provided for under this Agreement shall be
taken and construed as cumulative and in addition to every other remedy provided
for herein or by law.

      4. Except with respect to a termination by either party pursuant to the 
provisions of Section XV, no default by either party in the performance of 
any of its covenants or obligations hereunder, which except for this 
provision would be the legal basis for the right of rescission or termination 
of this Agreement by the other party, shall give or result in such a right 
unless and until the defaulting party shall fail to correct or take all such 
actions as are necessary to correct such default within thirty days after 
written notice of claim of such default is given to the defaulting party by 
the other party.

                                     -20-
<PAGE>


      5. In no event shall either party be liable to the other for any 
consequential damages as the result of any breach of warranty or default in 
performance hereunder.

      SECTION XIV.  NOTICES.

      1. Any notice, request, consent, demand, report or statement which is 
given to, or served upon, any party under any provision of or in relation to
