or the business conducted thereat.  Such investigation may include, but need not
be limited to, the  performance  of soil and surface or ground  water  sampling,

Plant Property (as defined in the Use and Non-Disturbance Agreement) shall be at
Buyer's  expense;  provided  further  that  Buyer  shall have no  obligation  to
maintain such roads for use by any other Person. During the Use Period,  Sellers
shall permit Buyer (at no additional cost to Buyer) to store all or such portion
of the Facility at the Facility Site as Buyer may require.

                  (d) Sellers shall provide, or cause to be provided,  to Buyer,

disposal and telephone) required in connection with the maintenance, removal and
relocation of the Facility by Buyer, provided that Buyer shall reimburse Sellers
for any actual costs or expenses so incurred on behalf of Buyer. Buyer agrees to

Closing Date, the Facility shall have been materially and adversely  affected by
reason  of any loss,  taking,  condemnation,  destruction  or  physical  damage,

best  efforts,  at their own expense,  to repair the Facility such that it is in
materially  the  same   condition  as  it  was  prior  to  such  loss,   taking,

against,  and agree to defend  promptly  Buyer,  any  Affiliate of Buyer and the
officers, directors, employees, agents, representatives and advisors of Buyer or
any Affiliate of Buyer  (collectively,  "Buyer  Indemnified  Persons") from, and
reimburse Buyer  Indemnified  Persons for, any and all losses,  damages,  costs,

Buyer Indemnified  Person may at any time suffer or incur, or become subject to,
as a result of or in connection with: (i) any breach or inaccuracy of any of the
representations   and  warranties  made  by  Sellers  in  this  Agreement,   the
Transaction  Documents or any other agreement or instrument delivered by Sellers
pursuant  hereto or thereto;  (ii) any  failure of Sellers  (before or after the
Closing Date) to carry out, perform, satisfy and discharge any of its covenants,
agreements,  undertakings,  liabilities or obligations under this Agreement, the
Transaction  Documents or under any of the agreements and instruments  delivered
by  Sellers  pursuant  to  hereto or  thereto;  (iii)  claims  by third  parties
(including governmental authorities) against Buyer relating to the construction,
operation,  maintenance  and  ownership  by  Sellers  of the  Facility  and  the
performance by Sellers under the Contracts, in each case under this clause (iii)
for the period prior to the Effective Time;  (iv) any of the matters  referenced
in Schedules 3.5 and 3.11 attached hereto;  (v) any violations of, or failure to
operate  the  Facility  in  accordance  with,  necessary  permits  prior  to the

additional  or modified  terms under any  Contracts  (or  substitute  contracts)
required  for or  resulting  from  the  satisfaction  and  performance  of  such
obligations;  and (vii) any of the events, circumstances or conditions described
in Section 3.14, any

                                       35
<PAGE>

pollution  or threat to human health or the  environment  that (A) is related in
any way to Sellers' (or any other owner's  (including,  but not limited to, each
of the Real Property Owners) or operator's) management,  use, control, ownership
or operation of the  Facility or Facility  Site prior to the Closing,  including

operation of law; and (viii) any and all Excluded Liabilities.

                  (b) In the event a claim  against a Buyer  Indemnified  Person
arises that Buyer reasonably believes is covered by the indemnity  provisions of
Section  8.1(a),  notice shall be given promptly by Buyer to Sellers  containing
details  reasonably  sufficient  for Sellers to identify the nature and basis of
the claim.  Provided  that Sellers  admit in writing to Buyer that such claim is
covered by the indemnity  provisions of Section  8.1(a),  Sellers shall have the
right to contest and defend by all appropriate  legal proceedings such claim and
to control all settlements (unless Buyer agrees to assume the cost of settlement
and to forgo such  indemnity)  and to select lead  counsel to defend any and all
such claims at the sole cost and expense of Sellers; provided, however, that (i)
Sellers may not effect any settlement that could result in any cost,  expense or
liability  to Buyer  unless  Buyer  consents in writing to such  settlement  and
Sellers  agree to  indemnify  Buyer  therefor  and (ii) in the event  that Buyer
reaches  a  settlement  with  respect  to  such  a  claim,   Sellers  shall  not
unreasonably withhold their consent to such settlement. Buyer may select counsel
to participate with Sellers' counsel in any such defense, in which event Buyer's
counsel shall be at its own sole cost and expense.  In connection  with any such
claim,  action or  proceeding,  the Parties shall  cooperate with each other and
provide  each  other  with  access  to  relevant  books  and  records  in  their
possession.

                  (c)  Sellers  shall  not be  required  to  indemnify  and hold
harmless Buyer  Indemnified  Persons pursuant to Section 8.1(a)(i) in respect of
the  representations  and warranties made by Sellers herein unless such right to
indemnification  is asserted by Buyer  (whether or not such Losses have actually
been  incurred) by notice to Sellers within twelve (12) months after the Closing
Date, with the exception of (i) the  representations and warranties set forth in
Sections  3.4 and 3.19,  which must be asserted by Buyer  within the  applicable
statute of  limitations  or any  extensions  thereof  required by any applicable
authority  relating to the taxes or  assessments  giving rise to the Loss,  plus
sixty (60) days, (ii) the representations and

                                       36
<PAGE>

warranties set forth in Section 3.12, which must be asserted by Buyer within the
applicable  statute of limitations  for the violation of the underlying law that
forms the basis of such claim,  plus sixty (60) days, (iii) the  representations
and  warranties  set forth in Sections 3.1, 3.2, and 3.7, which shall be without
time  limitation,  and (iv) the  representations  and  warranties  set  forth in
Section 3.14,  which must be asserted within  twenty-four  (24) months after the
Closing Date.

                  (d)  Notwithstanding  the  foregoing,  Sellers  shall  not  be
required to indemnify  Buyer  Indemnified  Persons  under  Section  8.1(a)(i) in
respect of the representations and warranties made by Sellers (other than in the
case of fraud or  misrepresentation)  unless  the amount of all Losses for which
indemnification  is sought by Buyer  under  Section  8.1(a)(i)  exceeds,  in the
aggregate,  $75,000.00,  in which event, Sellers' indemnity obligation hereunder
would apply to all such Losses.  Sellers' aggregate  indemnification  obligation
pursuant  to  Section   8.1(a)(i)   shall  in  no  event   exceed  the  Purchase
Consideration paid to Sellers.

                  (e) Subject to Section 10.11, the indemnification  provided in
this Section 8.1,  including the limitations with respect thereto,  shall be the
exclusive  remedy  for  Buyer  with  respect  to  Losses  as a  result  of or in
connection with the matters described in Section 8.1(a)(i),  notwithstanding any
provisions  in this  Agreement or any other such  agreement or instrument to the
contrary.

         8.2 Buyer's Indemnity.

                  (a)  Buyer  hereby  indemnifies  and holds  harmless  from and
against, and agrees to defend promptly Sellers, any Affiliate of Sellers and the
officers, directors,  employees, agents, representatives and advisors of Sellers
or any Affiliate of Sellers (collectively,  "Sellers' Indemnified Persons") from
and reimburse Sellers' Indemnified Persons for, any and all Losses that Sellers'
Indemnified  Persons may at any time suffer or incur, or become subject to, as a
result of or in  connection  with:  (i) any breach or  inaccuracy  of any of the
representations  and  warranties  made by Buyer in this  Agreement  or any other
agreement or instrument  delivered by Buyer pursuant hereto; (ii) any failure by
Buyer to  carry  out,  perform,  satisfy  and  discharge  any of its  covenants,
agreements,  undertakings,  liabilities or  obligations  under this Agreement or
under any of the agreements and instruments  delivered by Buyer pursuant to this
Agreement;   and  (iii)  claims  by  third   parties   (including   governmental

                  (b) In the event a claim against a Sellers' Indemnified Person
arises that is covered by the  indemnity  provisions of Section  8.2(a),  notice
shall  be given  promptly  by  Sellers  to Buyer  containing  detail  reasonably
sufficient  for Buyer to  identify  the nature and basis of the claim.  Provided
that  Buyer  admits in  writing  to  Sellers  that such  claim is covered by the
indemnity  provisions of Section  8.2(a),  Buyer shall have the right to contest
and defend by all appropriate  legal  proceedings  such claim and to control all
settlements (unless Sellers agrees to assume the cost of settlement and to forgo
such  indemnity) and to select lead counsel to defend any and all such claims at
the sole cost and expense of Buyer;  provided,  however,  that (i) Buyer may not
effect any  settlement  that could  result in any cost,  expense or liability to
Sellers unless Sellers  consents in writing to such  settlement and Buyer agrees
to  indemnify  Sellers  therefor  and (ii) in the  event  that  Sellers  reach a
settlement with respect to such a claim,  Buyer shall not unreasonably  withhold
their consent to such settlement. Sellers may select counsel to participate with
Buyer's counsel in any such defense, in which event Sellers' counsel shall be at
the sole cost and expense of Sellers.  In connection with any such claim, action
or  proceeding,  the Parties  shall  cooperate  with each other and provide each
other with access to relevant books and records in their possession.

                  (c) Buyer shall not be required to indemnify and hold harmless
Sellers'  Indemnified  Persons  pursuant to Section  8.2(a)(i) in respect of the
representations  and  warranties  made by  Buyer  herein  unless  such  right to
indemnification is asserted by Sellers (whether or not such Losses have actually
been  incurred)  by notice to the Buyer  within  twelve  (12)  months  after the
Closing Date, with the exception of the representations and warranties set forth
in Sections 4.1 and 4.2, which shall be without time limitation.

                  (d) Notwithstanding the foregoing, Buyer shall not be required
to indemnify Sellers'  Indemnified Persons under Section 8.2(a)(i) in respect of
the  representations  and  warranties  made by Buyer  (other than in the case of
fraud  or  misrepresentation)   unless  the  amount  of  all  Losses  for  which
indemnification  is sought by Sellers under Section  8.2(a)(i)  exceeds,  in the
aggregate,  $75,000.00,  in which event,  Buyer's indemnity obligation hereunder
would apply to all such Losses.  Buyer's  aggregate  indemnification  obligation
pursuant  to  Section   8.2(a)(i)   shall  in  no  event   exceed  the  Purchase
Consideration paid to Sellers.

                  (e) Subject to Section 10.11, the indemnification  provided in
this Section 8.2, including the limitations with respect thereto, shall be the

                                       38
<PAGE>

exclusive  remedy  for  Sellers  with  respect  to  Losses  as a result of or in
connection with the matters described in Section 8.2(a)(i),  notwithstanding any
provisions  in this  Agreement or any other such  agreement or instrument to the
contrary.

         8.3 Bulk Sales Compliance.

         To the extent  applicable,  Sellers shall comply with the provisions of
the bulk sales law of any U.S. jurisdiction, and Sellers covenants and agrees to
pay and discharge when due all claims of any governmental entities and creditors
of Sellers and its  subsidiaries  that could be asserted against Buyer by reason
of such non-compliance. Sellers agrees to indemnify and hold Buyer harmless from
and against and shall on demand  reimburse Buyer for any and all Losses suffered
by Buyer by reason of Sellers' failure to pay and discharge any such claims.

         8.4 Additional Instruments.

         At any time and from time to time after the Closing,  at either Party's
request and without further consideration, Sellers or Buyer, as the case may be,
shall execute and deliver such other instruments of sale, transfer,  conveyance,
assignment  and  confirmation  and take such other  action  (including,  but not
limited to, the  filings of liens and  execution  of  financing  statements)  as
Sellers or Buyer may  reasonably  deem  necessary  or desirable in order to more
effectively transfer,  convey, and assign to Buyer, and confirm Buyer's title to
and  interest in and  responsibility  and  liability  for,  the Facility and the
consummation  of the  transactions  contemplated  herein.  Without  limiting the
generality of the  foregoing,  Sellers will  cooperate  with and assist Buyer in
renewing,  or  transferring,  into  Buyer's  name those  permits for which Buyer
requests  such  assistance  and  cooperation  at the  appropriate  time for such
renewal or transfer as determined by Buyer.

         8.5 Access to Books, Records and Employees.

         From and after the  Closing  Date,  Buyer  will  authorize  and  permit
Sellers and its respective representatives to have access during normal business
hours, upon reasonable notice and for reasonable  purposes and in such manner as
will not unreasonably  interfere with the conduct of Buyer's business,  to Books
and Records and within the  control of Buyer that relate to the  Facility.  From
and after the Closing  Date,  Sellers  will  authorize  and permit Buyer and its
representatives  to have access during normal  business  hours,  upon reasonable
notice and for reasonable

                                       39
<PAGE>

purposes and in such manner as will not unreasonably  interfere with the conduct
of Sellers'  business,  to all books and  records,  files,  documents  and other
correspondence  related to the Facility prior to the Effective  Time,  which are
not included  among the Books and Records.  Buyer and Sellers  agree to maintain
all books,  records,  files,  documents and other correspondence  related to the
Facility  prior to the Effective  Time for a period of seven (7) years after the
Closing Date.

tribunal,  administrative  agency or commission or other  governmental  or other
regulatory  authority or agency  shall issue an order,  decree or ruling or take
any other action,  which permanently  restrains,  enjoins or otherwise prohibits
the acquisition by Buyer of the Facility and such order, decree, ruling or other
action shall have become final and non-appealable;

                  (c) by either  Buyer or Sellers if the other Party or Parties,
as the case may be, shall have  breached in any  material  respect any of its or
their,  as the  case may be,  representations,  warranties,  covenants  or other
agreements  contained  in this  Agreement or any of the  Transaction  Documents,
which breach  cannot be or has not been cured within  thirty (30) days after the
giving of written notice thereof by such non-breaching Party; or

                  (d) by either  Sellers or Buyer if the Closing  Date shall not
have occurred on or before January 31, 2000; provided,  however,  that the right
to terminate this  Agreement  pursuant to this clause (d) shall not be available
to any Party whose failure to fulfill any  obligation  under this  Agreement has
been the cause of, or  resulted  in, the  failure of the  Closing  Date to occur
prior to such date.

         9.2 Rights on Termination; Waiver.

respect to any fraud or breach of this Agreement prior to such termination.

                  (b) If any of the  conditions  set forth in Article VI of this
Agreement have not been satisfied,  Buyer may  nevertheless  elect to waive such
conditions and proceed with the  consummation of the  transactions  contemplated

termination of this Agreement shall be binding unless executed in writing by all
of the Parties.  No waiver of any of the provisions of this  Agreement  shall be
deemed or shall  constitute a waiver of any other  provision of this  Agreement,

         Except as otherwise  specifically  provided herein, each of the Parties
shall pay the fees and expenses of their  respective  counsel,  accountants  and

jurisdiction of any Federal court located in the Commonwealth of Kentucky or any
Kentucky  state court in the event of any dispute  arising out of or relating to

claim that any such  action  brought  in any such  court has been  brought in an

                  (b) Whenever the words  "include",  "includes" or  "including"

"without limitation."

                  (c) The words  "hereof",  "herein" and "herewith" and words of
similar import shall,  unless  otherwise  stated,  be construed to refer to this
Agreement as a whole and not to any particular provision of this Agreement,  and

         10.8 Severability.

         Any  term or  provision  of this  Agreement  that is held by a court of
competent  jurisdiction or other authority to be invalid,  void or unenforceable
in  any  situation  in  any  jurisdiction  shall  not  affect  the  validity  or
enforceability  of the remaining terms and provisions  hereof or the validity or
enforceability  of the offending term or provision in any other  situation or in
any  other  jurisdiction.  If  the  final  judgment  of  a  court  of  competent
jurisdiction  or other authority  declares that any term or provision  hereof is
invalid,  void or  unenforceable,  the parties  agree that the court making such
determination  shall  have the  power to reduce  the  scope,  duration,  area or
applicability of the term or provision,  to delete specific words or phrases, or
to replace any invalid,  void or unenforceable  term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision.

         10.9 No Reliance.

         No  third  party  is  entitled  to rely on any of the  representations,
warranties and agreements contained in this Agreement.  Buyer and Sellers assume
no liability to any third party because of any reliance on the  representations,
warranties  and  agreements  of Buyer or Sellers  contained  in this  Agreement.
Nothing contained in this Agreement shall be construed as creating a partnership
or joint venture or any agency  relationship  between the Parties,  or any other
relationship other than Buyer and Sellers as provided herein.

         10.10 Parties in Interest.

         This Agreement shall be binding upon and inure solely to the benefit of
each Party, and nothing in this Agreement, express or implied, is intended to or
shall  confer  upon any other  Person any  rights,  benefits  or remedies of any
nature whatsoever under or by reason of this Agreement.

         10.11 Specific Performance.

         The Parties agree that irreparable damage would occur in the event that
any of the provisions of this  Agreement  were not performed in accordance  with
the terms hereof or were otherwise  breached.  It is accordingly agreed that the
Parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement

                                       46

addition to any other remedy at law or equity.

         10.12 Time of Essence.

         Each of the Parties  hereby  agrees that,  with regard to all dates and
time periods set forth or referred to in this Agreement, time is of the essence.

         10.13 Representations, Warranties and Covenants.

         The  representations and warranties of each Party shall be deemed to be
material and to have been relied upon by the other Party.  The  representations,
warranties, covenants and agreements of Sellers and Buyer contained herein shall
survive the execution and delivery of this Agreement and the consummation of the
transactions  contemplated hereby and, as to the representations and warranties,
shall be effective  until the relevant time  limitation for making any indemnity
claim with respect to such representations and warranties under Sections 8.1 and
8.2. shall have been reached.

         10.14 Election of Remedies.

         Neither the exercise of nor the failure to exercise a right of set-off,
or to give notice of a claim under this  Agreement,  will constitute an election
of  remedies  or limit  Buyer in any  manner  in the  enforcement  of any  other
remedies that may be available to any of them, whether at law or in equity.

         10.15 TECO Coal Undertaking.

         In the event that Buyer shall fail to pay Pocahontas all or any portion
of the Subsequent  Consideration in accordance with the terms of this Agreement,
TECO Coal  agrees  that it shall,  subject to the terms and  conditions  of this
Agreement,  pay to Pocahontas the unpaid amount of the Subsequent  Consideration
which is due and payable under this  Agreement;  provided,  however,  that in no
event shall TECO Coal be  obligated  to pay  pursuant to this  Section  10.15 in
excess of an amount equal to the  Subsequent  Consideration,  less the amount of
any payment or payments made by, or on behalf of Buyer,  to Pocahontas  pursuant
to Section 2.2(b).
