                                   THE CLOSING


      3.1  Closing.  Upon the  terms  and  subject  to the  satisfaction  of the
conditions  contained in Article VII of this  Agreement,  the sale,  assignment,
conveyance,  transfer and delivery of the Purchased Assets to Buyer, the payment

or another  mutually  acceptable time and location,  on the date that is fifteen

                                      24





Closing is hereinafter called the "Closing Date." The Closing shall be effective
for all purposes as of 12:01 a.m. on the Closing Date.

      3.2  Payment  of  Purchase  Price.  Upon  the  terms  and  subject  to the
satisfaction of the conditions contained in this Agreement,  in consideration of
the  aforesaid  sale,  assignment,  conveyance,  transfer  and  delivery  of the
Purchased  Assets,  Buyer will pay or cause to be paid to Sellers at the Closing
an  aggregate  amount of five  hundred  forty six million  seven  hundred  fifty
thousand  seven hundred forty one United States  Dollars (U.S.  $546,750,741.00)
(the "Purchase Price") plus or minus any adjustments  pursuant to the provisions
of this Agreement,  by wire transfer of immediately  available funds denominated
in U.S. dollars or by such other means as are agreed upon by Sellers and Buyer.

      3.3 Adjustment to Purchase Price.  (a) Subject to Section  3.3(b),  at the
Closing, the Purchase Price shall be adjusted,  without duplication,  to account
for the items set forth in this Section 3.3(a):

                  (i) The Purchase  Price shall be increased  or  decreased,  as
      applicable,  to  reflect  the  difference  between  the book  value of all
      Inventories as of the Closing Date and the value of all  Inventories as of
      June 30, 1998 as reflected on Schedule 3.3(a)(i).

                  (ii) The  Purchase  Price shall be adjusted to account for the
      items prorated as of the Closing Date pursuant to Section 3.5.

                  (iii) The  Purchase  Price  shall be  increased  by the amount
      expended,  or for which  liabilities are incurred,  by Sellers between the
      date hereof and the Closing Date for capital  additions to or replacements
      of property,  plant and  equipment  included in the  Purchased  Assets and
      other expenditures or repairs on property, plant and equipment included in
      the Purchased  Assets that would be  capitalized  by Sellers in accordance
      with normal accounting  policies of Sellers and its Affiliates  (together,
      "Capital Expenditures"), which are not described on Schedule 6.1 and which
      either  (A)  are  mandated  after  the  date  of  this  Agreement  by  any
      Governmental  Authority  (subject to Buyer's  right  reasonably  to direct
      Sellers to contest such  mandates by  appropriate  proceedings  at Buyer's
      expense and provided there is no adverse impact on the Purchased  Assets);
      or (B) do not fall within category (A) above but do not exceed in

                                      25





      the aggregate $2 million for all Aggregate  Purchased  Assets;  or (C) are
      approved in writing by Buyer.

      (b) At least ten (10)  Business  Days prior to the Closing  Date,  Sellers
shall  prepare  and  deliver  to  Buyer  an  estimated  closing  statement  (the
"Estimated  Closing  Statement")  that shall set forth Sellers' best estimate of
the adjustments to the Purchase Price required by Section 3.3(a) (the "Estimated
Adjustment").  Within  five (5)  Business  Days  following  the  delivery of the
Estimated Closing Statement by Sellers to Buyer,  Buyer may object in good faith
to the  Estimated  Adjustment  in  writing.  If Buyer  objects to the  Estimated
Adjustment,   the  Parties  shall  attempt  to  resolve  their   differences  by
negotiation.  If the Parties are unable to do so within three (3) Business  Days
prior to the  Closing  Date  (or if  Buyer  does  not  object  to the  Estimated
Adjustment), the Purchase Price shall be adjusted (the "Closing Adjustment") for
the  Closing by the  amount of the  Estimated  Adjustment  not in  dispute.  The
disputed  portion  shall  be paid as a  Post-Closing  Adjustment  to the  extent
required by Section 3.3(c).

      (c) Within  sixty (60) days  following  the Closing  Date,  Sellers  shall
prepare  and  deliver  to Buyer a final  closing  statement  (the  "Post-Closing
Statement")  that shall set forth all adjustments to the Purchase Price required
by Section 3.3(a) (the "Post-Closing  Adjustment").  The Post-Closing  Statement
shall be prepared using the same accounting principles,  policies and methods as
Sellers have  historically  used in connection with the calculation of the items
reflected on such Post-Closing Statement.  Within thirty (30) days following the
delivery of the Post-Closing  Statement by Sellers to Buyer, Buyer may object to
the Post-Closing Adjustment in writing. Sellers agree to cooperate with Buyer to
provide  Buyer and  Buyer's  Representatives  information  used to  prepare  the
Post-Closing Statement and information relating thereto. If Buyer objects to the
Post-Closing  Adjustment,  the Parties  shall attempt to resolve such dispute by
negotiation.  If the Parties are unable to resolve  such dispute  within  thirty
(30) days of any objection by Buyer,  the Parties shall appoint the  Independent
Accounting Firm, which shall, at Sellers' and Buyer's joint expense,  review the
Post-Closing Adjustment and determine the appropriate adjustment to the Purchase
Price, if any, within thirty (30) days of such appointment. The Parties agree to
cooperate  with  the  Independent  Accounting  Firm  and  provide  it with  such
information as it reasonably  requests to enable it to make such  determination.
The finding of such Independent  Accounting Firm shall be binding on the Parties
hereto.  Upon  determination  of the appropriate  adjustment by agreement of the
Parties or by binding  determination of the Independent  Accounting Firm, if the
Post-
                                      26





Closing Adjustment is more or less than the Closing Adjustment,  the Party owing
the  difference  shall deliver such  difference to the other Party no later than
two (2) Business Days after such determination,  in immediately  available funds
or in any other manner as reasonably requested by the payee.

lease,  and  operate  its  material  properties  and  assets and to carry on its
business as is now being conducted. Such Seller is duly qualified to do business
as a  foreign  corporation  and is in  good  standing  under  the  laws  of each
jurisdiction in which its business as now being conducted shall require it to be
so  qualified,  except  where the  failure to be so  qualified  would not have a
Material  Adverse  Effect.  Such Seller has heretofore  delivered to Buyer true,
complete and correct copies of its  Certificate of  Incorporation  and Bylaws as
currently in effect.

      4.2 Authority  Relative to this Agreement.  Such Seller has full corporate
power and authority to execute and deliver this  Agreement and to consummate the
transactions  contemplated  by it hereby.  The  execution  and  delivery of this
Agreement by such Seller and the consummation of the  transactions  contemplated
by such Seller  hereby have been duly and validly  authorized  by all  necessary
corporate action required on the part of such Seller and this Agreement has been
duly and validly  executed and delivered by such Seller.  Subject to the receipt
of Sellers' Required Regulatory Approvals, this Agreement constitutes the legal,
valid and binding agreement of such Seller,  enforceable  against such Seller in
accordance  with its terms,  except that such  enforceability  may be limited by
applicable bankruptcy, insolvency,  reorganization,  fraudulent conveyance, 

                                      31





moratorium  or other  similar  laws  affecting  or  relating to  enforcement  of
creditors'  rights  generally and general  principles of equity  (regardless  of
whether enforcement is considered in a proceeding at law or in equity).

Schedule  4.3(a),  and  subject  to  obtaining   Sellers'  Required   Regulatory
Approvals,  neither the execution and delivery of this  Agreement by Sellers nor
the  consummation by Sellers of the  transactions  contemplated  hereby will (i)
conflict  with or result in any breach of any  provision of the  Certificate  of
Incorporation  or Bylaws of such Seller,  (ii) result in a default (or give rise
to any right of termination, consent, cancellation or acceleration) under any of
the terms,  conditions  or provisions of any note,  bond,  mortgage,  indenture,
material  agreement or other  instrument or obligation to which such Seller is a
party or by which it, or any of the  Purchased  Assets may be bound,  except for
such defaults (or rights of  termination,  cancellation or  acceleration)  as to
which  requisite  waivers or consents  have been  obtained or which,  would not,
individually or in the aggregate,  create a Material  Adverse  Effect;  or (iii)
constitute  violations  of  any  law,  regulation,  order,  judgment  or  decree
applicable to such Seller,  which violations,  individually or in the aggregate,
would create a Material Adverse Effect,  or create any Encumbrance  other than a
Permitted Encumbrance.

(i) such consents, approvals, filings or notices which, if not obtained or made,
will not prevent such Seller from performing its material obligations  hereunder
and (ii) such consents, approvals, filings or notices which become applicable to
such  Seller or the  Purchased  Assets as a result  of the  specific  regulatory
status of Buyer  (or any of its  Affiliates)  or as a result of any other  facts

its Affiliates) is or proposes to be engaged.

existing material defaults by such Seller or, to Sellers'  Knowledge,  any other

Assets except where the failure to have such Permits would not,  individually or
in the  aggregate,  create a Material  Adverse  Effect.  Except as  disclosed on

such Seller.

Property used in and,  individually or in the aggregate with other  Intellectual

Schedule  4.16,  (i) such Seller is not,  nor has it received any notice that it
is, in default (or with the giving of notice or lapse of time or both,  would be
in default),  under any contract to use such Intellectual  Property, and (ii) to
such Seller's  Knowledge,  such Intellectual  Property is not being infringed by
any other Person.  Neither Seller has received  notice that it is infringing any
Intellectual  Property of any other Person in  connection  with the operation or
business of the Purchased  Assets,  and such Seller,  to its  Knowledge,  is not
infringing  any  Intellectual  Property of any other Person the effect of which,
individually or in the aggregate, would have a Material Adverse Effect.

is a holding company  registered under the Public Utility Holding Company Act of
1935.

reorganization,   fraudulent  conveyance,   moratorium  or  other  similar  laws
affecting or relating to enforcement of creditors'  rights generally and general
principles  of equity  (regardless  of whether  enforcement  is  considered in a
proceeding at law or in equity).

      5.3   Consents and Approvals; No Violation.

            (a) Except as set forth in Schedule 5.3(a), and subject to obtaining
Buyer Required Regulatory Approvals,  neither the execution and delivery of this
Agreement  by  Buyer  nor  the   consummation  by  Buyer  of  the   transactions
contemplated  hereby  will (i)  conflict  with or  result  in any  breach of any
provision  of the  Certificate  of  Incorporation  or Bylaws  (or other  similar
governing  documents) of Buyer, or (ii) result in a default (or give rise to any
right of  termination,  cancellation  or  acceleration)  under any of the terms,
conditions  or  provisions  of any note,  bond,  mortgage,  indenture,  material
agreement  or  other  instrument  or  obligation  to  which  Buyer or any of its
Subsidiaries is a party or by which any of their respective assets may be bound,
except  for  such   defaults  (or  rights  of   termination,   cancellation   or

which  would not,  individually  or in the  aggregate,  have a material  adverse
effect on the business, assets, operations or condition (financial or otherwise)
of Buyer ("Buyer Material Adverse Effect") or (iii) violate any law, regulation,
order, judgment or decree applicable to Buyer, which violations, individually or
in the aggregate, would create a Buyer Material Adverse Effect.

            (b)  Except  as set  forth  in  Schedule  5.3(b)  (the  filings  and
approvals  referred  to in such  Schedule  are  collectively  referred to as the

delivery of this Agreement,  or the  consummation  by Buyer of the  transactions

                                      45

Material  Adverse  Effect.  Buyer is not subject to any  outstanding  judgments,
rules,  orders,  writs,  injunctions  or  decrees of any  court,  arbitrator  or
Governmental Authority which would,  individually or in the aggregate,  create a
Buyer Material Adverse Effect.

by  Sellers  of any  representation  or  warranty  of  Sellers,  or of any other
condition or circumstance that would excuse Buyer from its timely performance of

Environmental  Permits  necessary  for Buyer to own and  operate  the  Purchased
Assets as of the Closing. Without limiting the foregoing,  Buyer is not aware of

defined  in  the  Public  Utility  Holding  Company  Act  of  1935)  status  and
market-based rate authorization specified in items 3 and 2 of Schedule 5.3(b).

warranties   and  covenants   contained  in  this  Agreement  or  the  Ancillary
Agreements, Buyer acknowledges and agrees that it has, prior to its execution of

necessary for the purposes of acquiring the Purchased Assets for Buyer's

                                      46





intended use. Buyer acknowledges and agrees that it hereby assumes the risk that
adverse past,  present,  and future physical  characteristics  and Environmental
Conditions may not have been revealed by its Inspections and the  investigations
of the Purchased Assets contained in the  Environmental  Reports.  In making its
decision to execute this Agreement,  and to purchase the Purchased Assets, Buyer
has  relied on and will rely  upon,  among  other  things,  the  results  of its
Inspections and the Environmental Reports.

      6.2   Access to Information.

      (a)  Between the date of this  Agreement  and the  Closing  Date,  each of
Seller and Genco will, at reasonable times and upon reasonable  notice: (i) give
Buyer and its Representatives  reasonable access to its managerial personnel and
to all books,  records,  plans,  equipment,  offices  and other  facilities  and
properties  constituting  the  Purchased  Assets;  (ii) furnish  Buyer with such
financial  and  operating  data  and  other  information  with  respect  to such
Purchased Assets as Buyer may from time to time reasonably  request,  and permit
Buyer to make such reasonable
                                      49





Inspections  thereof as Buyer may request;  (iii) furnish Buyer at its request a
copy of each material report, schedule or other document filed by such Seller or
Genco or any of its Affiliates  with respect to such  Purchased  Assets with the
SEC, FERC, NJBPU,  PaPUC,  PaDEP or any other Governmental  Authority;  and (iv)
furnish Buyer with all such other  information as shall be reasonably  necessary
to enable Buyer to verify the accuracy of the  representations and warranties of
such Seller contained in this Agreement;  provided,  however,  that (A) any such
inspections  and  investigations  shall be  conducted in such a manner as not to
interfere  unreasonably  with the  operation of the Purchased  Assets,  (B) such
Seller or Genco shall not be required to take any action which would  constitute
a waiver of the attorney-client privilege, and (C) such Seller or Genco need not
supply Buyer with any information which such Seller or Genco is under a legal or
contractual obligation not to supply.  Notwithstanding  anything in this Section
6.2 to the contrary,  Sellers and Genco will only furnish or provide such access
to Transferring Employee Records and will not furnish or provide access to other
employee  personnel  records or medical  information  unless  required by law or
specifically authorized by the affected employee, nor shall Buyer have the right
to  administer to any of Sellers' or Genco's  employees  any skills,  aptitudes,
psychological  profile,  or other employment  related test. Buyer shall not have
the right to perform or conduct  any  environmental  sampling or testing at, in,
on, or underneath the Purchased Assets.

      (b) Each  Party  shall,  and  shall  use its  best  efforts  to cause  its
Representatives  to, (i) keep all  Proprietary  Information  of the other  Party
confidential and not to disclose or reveal any such  Proprietary  Information to
any  person  other  than  such  Party's  Representatives  and  (ii) not use such
Proprietary  Information  other than in connection with the  consummation of the
transactions  contemplated  hereby.  After the  Closing  Date,  any  Proprietary
Information  to the extent  related to the  Purchased  Assets shall no longer be
subject to the  restrictions  set forth herein.  The  obligations of the Parties
under this Section  6.2(b) shall be in full force and effect for three (3) years
from the date hereof and will survive the  termination  of this  Agreement,  the
discharge  of all other  obligations  owed by the  Parties to each other and the
closing of the transactions contemplated by this Agreement.

      (c) For a period of seven (7) years after the Closing Date (or such longer
period as may be required by applicable law or Section  6.8(g)),  each Party and
its Representatives shall have reasonable access to all of the books and records
of the Purchased  Assets,  including all  Transferring  Employee  Records in the
possession of the other Party to the extent that such access
                                      50





may  reasonably  be  required  by such  Party in  connection  with  the  Assumed
Liabilities  or the  Excluded  Liabilities,  or  other  matters  relating  to or
affected by the operation of the Purchased Assets. Such access shall be afforded
by the  Party in  possession  of any such  books and  records  upon  receipt  of
reasonable  advance written notice and during normal  business hours.  The Party
exercising  this right of access  shall be solely  responsible  for any costs or
expenses  incurred by it or the other Party with respect to such access pursuant
to this Section  6.2(c).  If the Party in  possession  of such books and records
shall desire to dispose of any books and records upon or prior to the expiration
of such seven-year period (or any such longer period),  such Party shall,  prior
to such disposition, give the other Party a reasonable opportunity at such other
Party's  reasonable  expense,  to segregate and remove such books and records as
such other Party may select.

      (d)  Notwithstanding  the terms of Section 6.2(b) above, the Parties agree
that prior to the Closing Buyer may reveal or disclose  Proprietary  Information
to any other Persons in connection with Buyer's financing of its purchase of the
Purchased  Assets  or  any  equity  participation  in  Buyer's  purchase  of the
Purchased  Assets  (provided  that such Persons agree in writing to maintain the
confidentiality   of  the  Proprietary   Information  in  accordance  with  this
Agreement).

      (e) Upon the other  Party's  prior  written  approval  (which  will not be
unreasonably  withheld  or  delayed),   either  Party  may  provide  Proprietary
Information of the other Party to the NJBPU, the PaPUC, the SEC, the FERC or any
other Governmental  Authority with jurisdiction or any stock exchange, as may be
necessary to obtain Sellers' Required  Regulatory  Approvals,  or Buyer Required
Regulatory Approvals, respectively, or to comply generally with any relevant law
or regulation.  The disclosing  Party will seek  confidential  treatment for the
Proprietary   Information  provided  to  any  Governmental   Authority  and  the
disclosing Party will notify the other Party as far in advance as is practicable
of its  intention  to  release to any  Governmental  Authority  any  Proprietary
Information.

      (f)  Except as  specifically  provided  herein  or in the  Confidentiality
Agreement,  nothing in this Section  shall impair or modify any of the rights or
obligations of Buyer or its Affiliates under the Confidentiality  Agreement, all
of which remain in effect until termination of such agreement in accordance with
its terms.

      (g) Except as may be permitted  in the  Confidentiality  Agreement,  Buyer
agrees that, prior to the Closing Date, it will

                                      51






not contact any vendors,  suppliers,  employees, or other contracting parties of
Sellers,  Genco or their  Affiliates with respect to any aspect of the Purchased
Assets or the  transactions  contemplated  hereby,  without  the  prior  written
consent of Sellers, which consent shall not be unreasonably withheld.

      6.3  Public  Statements.  Subject  to  the  requirements  imposed  by  any
applicable law or any  Governmental  Authority or stock  exchange,  prior to the
Closing Date, no press release or other public  announcement or public statement
or comment in response to any inquiry relating to the transactions  contemplated
by this  Agreement  shall be  issued  or made by any  Party  without  the  prior
approval  of the  other  Parties  (which  approval  shall  not  be  unreasonably
withheld). The Parties agree to cooperate in preparing such announcements.

      6.4 Expenses.  Except to the extent specifically provided herein,  whether
or not the  transactions  contemplated  hereby  are  consummated,  all costs and
expenses  incurred  in  connection  with  this  Agreement  and the  transactions
contemplated  hereby  shall be borne  by the  Party  incurring  such  costs  and
expenses.  Notwithstanding  anything  to the  contrary  herein,  Buyer  will  be
responsible for (a) all costs and expenses  associated with the obtaining of any
title insurance policy and all endorsements  thereto that Buyer elects to obtain
and (b) all filing fees under the HSR Act.

      6.5   Further Assurances.

      (a) Subject to the terms and  conditions  of this  Agreement,  each of the
Parties  hereto  shall use its best efforts to take,  or cause to be taken,  all
actions,  and to do,  or cause to be  done,  all  things  necessary,  proper  or
advisable under applicable laws and regulations to consummate and make effective
the purchase and sale of the Purchased Assets pursuant to this Agreement and the
assumption of the Assumed  Liabilities,  including without  limitation using its
best efforts to ensure satisfaction of the conditions  precedent to each Party's
obligations  hereunder,  including obtaining all necessary consents,  approvals,
and authorizations of third parties and Governmental  Authorities required to be
obtained in order to consummate the transactions hereunder,  and to effectuate a
transfer  of the  Transferable  Permits to Buyer.  Buyer  agrees to perform  all
conditions  required of Buyer in connection  with Sellers'  Required  Regulatory
Approvals,  other than those  conditions  which  would  create a Buyer  Material
Adverse  Effect.  Neither of the Parties  hereto  shall,  without  prior written
consent  of the  other  Party,  take or fail to take  any  action,  which  might
reasonably be expected to prevent or materially impede,  interfere with or delay
the transactions contemplated by this Agreement.
                                      52





      (b) Buyer agrees that prior to the Closing Date,  neither Buyer nor any of
its  Affiliates  will enter into any other  contract  to acquire,  nor  acquire,
electric  generation  facilities  located in the control area  recognized by the
North  American  Reliability  Council as the PJM  Control  Area if the  proposed
acquisition of such additional electric  generation  facilities might reasonably
be  expected  to  prevent  or  materially  impede,  interfere  with or delay the
transactions contemplated by this Agreement. Buyer shall give Sellers reasonable
advance notice (and in any event not less than 30 days) before Buyer enters into
contracts  to acquire or acquires any electric  generation  facility  located in
said PJM Control Area.

      (c) In the event that any Purchased  Asset shall not have been conveyed to
Buyer at the Closing,  each Seller shall, subject to Section 6.5(d) and (e), use
Commercially  Reasonable Efforts to convey such asset to Buyer as promptly as is
practicable after the Closing.

      (d) To the extent that  Sellers'  rights under any  Sellers'  Agreement or
Real Property  Lease may not be assigned  without the consent of another  Person
which consent has not been obtained by the Closing Date,  this  Agreement  shall
not constitute an agreement to assign the same, if an attempted assignment would
constitute a breach thereof or be unlawful.  Sellers and Buyer agree that if any
consent to an  assignment  of any material  Sellers'  Agreement or Real Property
Lease shall not be obtained or if any attempted  assignment would be ineffective
or would impair  Buyer's  rights and  obligations  under the  material  Sellers'
Agreement or Real Property Lease in question,  so that Buyer would not in effect
acquire the benefit of all such rights and obligations,  the applicable  Seller,
at Buyer's option and to the maximum  extent  permitted by law and such material
Sellers'  Agreement  or Real  Property  Lease,  shall,  after the Closing  Date,
appoint Buyer to be such Seller's  agent with respect to such material  Seller's
Agreement or Real Property Lease, or, to the maximum extent permitted by law and
such  material  Sellers'  Agreement  or Real  Property  Lease,  enter  into such
reasonable  arrangements  with Buyer or take such other actions as are necessary
to provide Buyer with the same or  substantially  similar rights and obligations
of such  material  Sellers'  Agreement  or Real  Property  Lease  as  Buyer  may
reasonably  request.  Sellers  and Buyer  shall  cooperate  and  shall  each use
Commercially Reasonable Efforts prior to and after the Closing Date to obtain an
assignment of such material Sellers' Agreement or Real Property Lease to Buyer.

      (e) To the extent  that  Sellers'  rights  under any  warranty or guaranty
described in Section 2.1(i) may not be assigned
                                      53





without the consent of another  Person,  which  consent has not been obtained by
the Closing Date,  this  Agreement  shall not  constitute an agreement to assign
same,  if an  attempted  assignment  would  constitute a breach  thereof,  or be
unlawful.  Sellers and Buyer agree that if any consent to an  assignment  of any
such warranty or guaranty shall not be obtained,  or if any attempted assignment
would be ineffective or would impair  Buyer's rights and  obligations  under the
warranty or guaranty in question,  so that Buyer would not in effect acquire the
benefit of all such rights and obligations,  the applicable  Seller,  at Buyer's
expense,  shall use Commercially  Reasonable Efforts, to the extent permitted by
law and such warranty or guaranty,  to enforce such warranty or guaranty for the
benefit of Buyer so as to provide Buyer to the maximum extent  possible with the
benefits and obligations of such warranty or guaranty.

      (f) Between the date hereof and the Closing, Buyer shall have the right to
commence the regulatory approval processes  associated with the construction and
operation of new, modified or repowered electric generating units and associated
equipment at the Real Property.  Sellers shall provide reasonable  assistance to
Buyer, under Buyer's reasonable direction, in obtaining all Permits required (i)
to own and operate the Purchased Assets as contemplated by the Agreement and the
Ancillary  Agreements  and (ii) to  construct  and operate  such new or modified
facilities,  provided,  however,  that Buyer  shall  reimburse  Sellers  for all
reasonable costs incurred by Sellers in its assistance of Buyer hereunder.

      (g)  Sellers  agree  to use  Commercial  Reasonable  Efforts  to have  the
co-owners of the Keystone and Conemaugh  Stations enter into an  interconnection
agreement  with  Seller  (substantially  in the  form  of the  agreements  being
executed by Buyer and JCP&L, Met-Ed and Penelec, respectively, relating to other
generating stations). Pending any such agreement, following the Closing, Sellers
agree to continue to provide interconnection service to each Station on the same
terms and conditions as they are currently so providing.

      6.6   Consents and Approvals.

      (a) As promptly as possible after the date of this Agreement,  Sellers and
Buyer,  as  applicable,  shall each file or cause to be filed  with the  Federal
Trade Commission and the United States  Department of Justice any  notifications
required to be filed under the HSR Act and the rules and regulations promulgated
thereunder with respect to the  transactions  contemplated  hereby.  The Parties
shall use their  respective best efforts to respond promptly to any requests for
additional

                                      54






information  made by either of such agencies,  and to cause the waiting  periods
under the HSR Act to terminate or expire at the earliest possible date after the
date of filing.  Buyer will pay all filing fees under the HSR Act but each Party
will bear its own costs of the preparation of any filing.

      (b) As promptly as possible after the date of this Agreement,  Buyer shall
file with the FERC an application  requesting Exempt Wholesale  Generator status
for Buyer,  which filing may be made  individually  by Buyer or jointly with the
Sellers in  conjunction  with other  filings to be made with the FERC under this
Agreement,  as reasonably determined by the Parties. Prior to Buyer's submission
of that  application  with the FERC,  Buyer shall submit such application to the
Sellers for review and comment and Buyer shall  incorporate into the application
any revisions reasonably requested by Sellers. Buyer shall be solely responsible
for the cost of  preparing  and filing this  application,  any  petition(s)  for
rehearing,  or any  re-application.  If Buyer's  initial  application for Exempt
Wholesale Generator status is rejected by the FERC, Buyer agrees to petition the
FERC for  rehearing  and/or  to  re-submit  an  application  with the  FERC,  as
reasonably  required  by the  Sellers,  provided  that in either case the action
directed by the Sellers does not create a Buyer Material Adverse Effect.

      (c) As promptly as possible after the date of this Agreement,  Buyer shall
file with the FERC an application requesting  authorization under Section 205 of
the Federal Power Act to sell electric  generating  capacity and energy, but not
other services, including, without limitation,  ancillary services, at wholesale
at market-based rates, which filing may be made individually by Buyer or jointly
with Sellers in  conjunction  with other  filings to be made with the FERC under
this Agreement,  as reasonably determined by the Parties. Prior to the filing of
that  application  with the FERC,  Buyer shall  submit such  application  to the
Sellers for review and comment and Buyer shall  incorporate into the application
any  revisions  reasonably  requested  by the  Sellers.  Buyer  shall be  solely
responsible  for  the  cost  of  preparing  and  filing  this  application,  any
petition(s) for rehearing, or any reapplication.  If Buyer's initial application
for  market-based  rate  authorization  results in a FERC request for additional
information  or is rejected by the FERC,  Buyer shall  provide that  information
promptly,  to petition the FERC for rehearing and/or to re-submit an application
with the FERC, as reasonably required by the Sellers,  provided that the Sellers
shall have a  reasonable  opportunity  to make  changes  to such a  petition  or
re-submission application and,



                                      55






provided  further,  that the action  directed  by Seller does not create a Buyer
Material Adverse Effect.

      (d) As promptly as possible, and in any case within sixty (60) days, after
the date of this Agreement,  Sellers and Buyer,  as applicable,  shall file with
the NJBPU, the PaPUC, the FERC and any other  Governmental  Authority,  and make
any  other  filings  required  to be  made  with  respect  to  the  transactions
contemplated  hereby.  The Parties  shall  respond  promptly to any requests for
additional  information  made by such agencies,  and use their  respective  best
efforts to cause  regulatory  approval to be obtained at the  earliest  possible
date  after  the date of  filing.  Each  Party  will  bear its own  costs of the
preparation of any such filing.

      (e) Without limitation of Section 10.11, Sellers and Buyer shall cooperate
with each other and promptly  prepare and file  notifications  with, and request
Tax clearances  from,  state and local taxing  authorities in  jurisdictions  in
which a portion of the Purchase Price may be required to be withheld or in which
Buyer would otherwise be liable for any Tax  liabilities of Sellers  pursuant to
such state and local Tax law.

      (f) Buyer shall have the primary responsibility for securing the transfer,
reissuance or procurement of the Permits and  Environmental  Permits (other than
Transferable  Permits) effective as of the Closing Date. Sellers shall cooperate
with Buyer's  efforts in this regard and assist in any transfer or reissuance of
a Permit or Environmental Permit held by Sellers or the procurement of any other
Permit or Environmental Permit when so requested by Buyer.

      6.7 Fees and Commissions.  Each Seller, on the one hand, and Buyer, on the
other hand, represent and warrant to the other that, except for Goldman, Sachs &
Co., which are acting for and at the expense of such Seller,  no broker,  finder
or other Person is entitled to any brokerage fees,  commissions or finder's fees
in connection with the transaction  contemplated  hereby by reason of any action
taken by the Party making such representation. Each Seller, on the one hand, and
Buyer, on the other hand, will pay to the other or otherwise discharge, and will
indemnify and hold the other  harmless  from and against,  any and all claims or
liabilities  for all brokerage  fees,  commissions and finder's fees (other than
the fees,  commissions  and finder's  fees payable to the parties  listed above)
incurred by reason of any action taken by the indemnifying party.

      6.8   Tax Matters.


                                      56





      (a) All  transfer  and  sales  taxes  incurred  in  connection  with  this
Agreement  and  the  transactions   contemplated   hereby  (including,   without
limitation,  (a) Pennsylvania and New Jersey sales tax; and (b) the Pennsylvania
and New  Jersey  realty  transfer  taxes on  conveyances  of  interests  in real
property  (including such taxes assessed by Pennsylvania  municipalities as well
as by the Commonwealth of Pennsylvania  itself)) shall be borne by Buyer. Except
for the  Pennsylvania  Realty  Transfer Tax  Statement of Value,  which shall be
filed by Buyer,  Sellers shall file, to the extent  required by, or  permissible
under,  applicable law, all necessary Tax Returns and other  documentation  with
respect to all such  transfer  and sales taxes,  and, if required by  applicable
law,  Buyer  shall  join in the  execution  of any such Tax  Returns  and  other
documentation.  Prior to the Closing Date, to the extent applicable, Buyer shall
provide  to  Sellers  appropriate   certificates  of  Tax  exemption  from  each
applicable taxing authority.

      (b) With respect to Taxes to be prorated in accordance with Section 3.5 of
this Agreement,  Buyer shall prepare and timely file all Tax Returns required to
be filed after the Closing Date with respect to the  Purchased  Assets,  if any,
and  shall  duly  and  timely  pay all  such  Taxes  shown to be due on such Tax
Returns.  Buyer's  preparation  of any such Tax  Returns  shall  be  subject  to
Sellers'  approval,  which approval shall not be  unreasonably  withheld.  Buyer
shall make such Tax Returns  available for Sellers' review and approval no later
than fifteen (15)  Business  Days prior to the due date for filing each such Tax
Return.

      (c) Within  fifteen (15)  Business  Days after  receipt of such Tax Return
referred  to in Section  6.8(b),  each Seller  shall pay to Buyer such  Sellers'
share of the amount shown on such Tax Return,  less  payments on account of such
Taxes previously made by each Seller.  To the extent that such Sellers' previous
payments  exceed such  Sellers'  share,  the Buyer shall pay such excess to such
Seller.  With  respect  to real  estate  taxes,  evidence  of  payment  shall be
delivered by each Seller to Buyer at the Closing.  As soon as practicable  after
the  Closing,  Sellers  and Buyer  shall  cooperate  in the filing of an amended
return  and/or  other  documents  in order to obtain the  available  refund with
respect to any Closing Year PURTA Tax. Buyer shall be entitled to such refund to
the extent, but only to the extent, that it does not exceed any payments made by
Buyer on account of such PURTA liability.

      (d) Buyer and Sellers shall provide the other with such  assistance as may
reasonably be requested by the other Party in connection with the preparation of
any Tax Return,  any audit or other examination by any taxing authority,  or any
judicial or administrative proceedings relating to liability for Taxes, and
                                      57





each  shall  retain  and  provide  the  requesting  party  with any  records  or
information  which  may be  relevant  to  such  return,  audit,  examination  or
proceedings.  Any  information  obtained  pursuant  to this  Section  6.8(d)  or
pursuant to any other Section hereof providing for the sharing of information or
review of any Tax Return or other  instrument  relating  to Taxes  shall be kept
confidential  by the parties  hereto.  Schedule 6.8 sets forth  procedures to be
followed with respect to the tax appeals and audits referred to therein.

      (e) Genco Tax matters.

      (1) Section 338(h)(10) Election. (i) With respect to the sale of the Genco
Stock,  GPU and Buyer shall  jointly make the  election  provided for by section
338(h)(10) of the Code and Section  1.338(h)(10)-1  of the Treasury  Regulations
promulgated under the code and any comparable  election under state or local tax
law (the  "Election").  As soon as  practicable  after the  Closing  Date,  with
respect to such Election,  GPU and Buyer shall  mutually  prepare a Form 8023-A,
with all attachments,  and GPU shall sign such Form 8023-A.  Buyer and GPU shall
also  cooperate  with each other to take all actions  necessary and  appropriate
(including filing such additional forms, returns, elections, schedules and other
documents as may be required) to effect and preserve such Election in accordance
with the provisions of Section  1.338(h)(10)-1  of the Treasury  Regulations (or
any  comparable  provisions  of  state  and  local  tax  law)  or any  successor
provisions.

      (ii) With respect to the  Election,  the parties  shall  endeavor to agree
upon the  amount of the  Modified  Aggregate  Deemed  Sales  Price as defined in
Section  1.338(h)(10)-1  of the Treasury  Regulations  (the "Modified ADSP") and
upon an allocation  of such Modified ADSP among the assets of Genco  pursuant to
Treasury Regulation Section  1.338(h)(10)-1.  Buyer and GPU shall use their good
faith  Commercially  Reasonable Efforts to agree upon such allocation within one
hundred twenty (120) days of the date of this  Agreement.  In the event that the
parties  cannot  agree on a mutually  satisfactory  allocation  within said time
period,  the  Independent  Accounting  Firm shall,  at GPU's and  Buyer's  joint
expense,  determine the appropriate allocation.  The finding of such Independent
Accounting  Firm shall be  binding on the  parties.  The  parties  shall take no
action  inconsistent with, or fail to take any action necessary for the validity
of the Election,  and shall adopt and utilize the asset values  determined  from
such reasonable allocation for the purpose of all Tax Returns filed by them, and
shall not voluntarily take any action inconsistent therewith upon examination of
any Tax Return, in any refund claim, in any litigation or otherwise with respect
to such
                                      58






Tax Returns.  Buyer and GPU shall  notify and provide the other with  reasonable
assistance in the event of an examination,  audit or other proceeding  regarding
the agreed upon allocation of the Modified ADSP.

      (2) Return Filing, Payments, Refunds and Credits. Notwithstanding anything
to the contrary in Section 3.5 of this Agreement,

      (i) For  purposes  of  this  Agreement,  the  amount  of  Taxes  of  Genco
attributable to the pre-Closing  portion of any taxable period  beginning before
and ending after the Closing  Date (the  "Straddle  Period")  shall be allocated
between the pre-Closing and post-Closing portions based, in the case of real and
personal property taxes, on a per diem basis, and in the case of all other Taxes
(including,  without limitation, Income Taxes), on the actual activities, income
or loss of Genco  during  such  pre-Closing  and  post-Closing  portions  of the
Straddle  Period  assuming a hypothetical  closing of the books as of the end of
the  Closing  Date;  provided,  further,  that  the  taxes  of  Genco  that  are
attributable to the pre-Closing  portion of any taxable period shall include any
Taxes  resulting from the gain on any deemed sale of assets by Genco pursuant to
Section 338 of the Code or any comparable  provision under the laws of any other
jurisdiction with respect to the transactions contemplated by this Agreement.

      (ii) Buyer and GPU shall cause Genco to join, for all pre-Closing  periods
and the Straddle Period for which Genco is required or eligible to do so, in all
consolidated,  combined  or  unitary  federal,  state,  or Local  Income  Tax or
franchise Tax Returns of GPU (or any Tax Affiliate for all  pre-Closing  periods
("GPU's Tax Returns") and shall, in each jurisdiction  where this is required or
permissible  under  applicable law, cause the taxable year of Genco to terminate
as of the Closing Date. GPU shall cause to be prepared and timely filed all such
GPU's Tax Returns and shall pay or cause to be paid all Taxes shown to be due on
such  GPU's  Tax  Returns;  provided,  however,  that in the case of a GPU's Tax
Return for the Straddle  Period,  Buyer shall or shall cause Genco to pay to GPU
the portion of such Taxes shown to be due thereon  attributable to Genco for the
post-Closing  Date portion of the Straddle Period  determined in accordance with
Section 6.8(e)(2)(i) and the GPU Intercompany Tax Allocation Agreement in effect
on the  date of the  signing  of  this  Agreement  (the  "GPU  Intercompany  Tax
Allocation Agreement").

      (iii)  Buyer  shall or shall  cause  Genco to prepare  and timely file all
Income Tax Returns of Genco for all pre-Closing periods and the Straddle Period,
other than those referred to in Section 6.8(e)(2)(ii),  which Income Tax Returns
have not been filed as of the  Closing  Date,  and shall cause to be timely paid
all Taxes
                                      59





shown to be due on such Tax  Returns.  No later  than ten days  prior to the due
date for the filing of each Income Tax Return  referred  to in this  section 6.8
(e)(2)(iii),  GPU shall pay to Genco the  amount of Taxes  shown as due  thereon
less any estimated Taxes paid by Genco during the pre-Closing period;  provided,
however,  that in the case of an Income Tax Return  for a Straddle  Period,  GPU
shall  only  be  required  to pay  Genco  the  portion  of  such  Taxes  that is
attributable to the pre-Closing Date portion of such Straddle Period, determined
in accordance with Section  6.8(e)(2)(i) and the GPU Intercompany Tax Allocation
Agreement less any estimated Taxes paid by Genco during the pre-Closing  period.
GPU shall fully  cooperate with Buyer and Genco in accordance with past practice
in the  preparation  of the  Income Tax Return as  referred  to in this  Section
6.8(e)(2)(iii).


      (iv) Buyer  shall or shall  cause Genco to prepare and timely file all Tax
Returns for all pre-Closing  periods and the Straddle  Period,  other than those
Tax Returns referred to in Section  6.8(e)(2)(ii)  and (iii),  which Tax Returns
have not been filed as of the  Closing  Date,  and shall cause to be timely paid
all Taxes shown to be due thereon.  No later than ten days prior to the due date
for the filing of each Tax Return referred to in this Section 6.8(e)(2)(iv), GPU
shall  pay to  Genco  the  amount  shown  as  due  thereon  attributable  to the
pre-Closing Date portion of the Straddle Period less any estimated Taxes paid by
Genco during the pre-Closing period.

      (v) The Tax Returns referred to in Section  6.8(e)(2)(ii),  (iii) and (iv)
shall be prepared in a manner  consistent with past practice,  unless a contrary
treatment is required by an intervening  change in the applicable law. GPU shall
cause to be made available to Buyer a copy of any Tax Return that is required to
be filed by GPU or Genco  under  6.8(e)(2)(ii)  and Buyer shall cause to be made
available  to Seller a copy of any Tax Return  that is  required  to be filed by
Buyer or Genco under Section  6.8(e)(2)(iii) or (iv), in each case together with
all relevant  work papers and other  information.  Each such Tax Return shall be
made  available  for review and approval no later than 20 Business Days prior to
the due date for the  filing of such Tax  Return  (taking  into  account  proper
extensions),  such approval not be unreasonably  withheld.  An exact copy of any
such Tax Return  filed by Buyer shall be provided to GPU and any such Tax Return
filed by GPU shall be  provided to Buyer,  in each case,  no later than ten days
after such Tax Return is filed.  To the extent that the Tax Returns that are the
subject of this  clause (v) are  combined  or  consolidated  tax  returns,  each
reference to Tax Return shall be to a pro forma separate return of Genco.

                                      60






      (vi) Any  refunds  or  credits  of the  Taxes of Genco  plus any  interest
received with respect  thereto from the applicable  taxing  authorities  for any
pre-Closing  period (including  without  limitation,  refunds or credits arising
from amended  returns  filed after the Closing Date) shall be for the account of
GPU,  except to the extent that such refunds or credits are  attributable to the
mandatory carryback of any deductions or credits for any Tax Period ending after
a Closing  Date and, if received by Buyer or Genco,  shall be paid to GPU within
ten days after Buyer or Genco  receives  such refund or after the  relevant  Tax
Return is filed  within which the credit is applied  against  Buyer's or Genco's
liability for Taxes for a period which begins after the Closing Date, net of any
Taxes Buyer or Genco is required to pay on account of  receiving  such refund or
credit  (including  a reasonable  estimate of resulting  future Tax costs.) GPU,
without the consent of Buyer,  shall not apply for any refund that will create a
material  adverse  effect on any  post-Closing  period  Tax Return and shall not
apply for any  refund for any  Straddle  Period Tax Return or any Tax Return for
Genco that is not a consolidated,  combined,  or unitary Tax Return. Any refunds
or  credits  of Taxes of Genco  for any  Straddle  Period  shall be  apportioned
between  GPU and Buyer in the same  manner as the  liability  for such  Taxes is
apportioned pursuant to Section 6.8(e)(2)(i).

      (3) Tax  Indemnification.  (i) Without  duplication,  GPU shall indemnify,
defend  and hold Buyer and Genco  harmless  from and  against  any and all Taxes
(including interest and penalties) which may be suffered or incurred by Buyer or
Genco in respect of or  relating  to,  directly  or  indirectly  (x) Taxes of or
attributable to Genco for all pre-Closing  periods, (y) Taxes of or attributable
to Genco with respect to the pre-Closing portion of the Straddle period, and (z)
Taxes payable by Genco with respect to any pre-Closing period or Straddle Period
by reason  of Genco  being  severally  liable  for the Tax of any Tax  Affiliate
pursuant to Treasury  Regulation  1.1502-6 or any  analogous  state or local Tax
law.

      (ii) Without duplication,  Buyer shall indemnify,  defend and hold GPU and
each of its  Affiliates  harmless from and against any and all Taxes  (including
interest and penalties)  which may be suffered or incurred by them in respect of
or relating to,  directly or indirectly  (x) Taxes of or  attributable  to Genco
with respect to all  post-Closing  periods,  and (y) Taxes of or attributable to
Genco with respect to the post-Closing portion of any Straddle Period.

      (iii) An indemnity  payment due under this Section 6.8(e)(4) shall be made
within thirty (30) days after (i) the party in

                                      61






control of the issue  under  Section  6.8(e)(3)  determines  not to contest  the
issue,  the receipt of a formal notice or assessment from a taxing  authority or
the  occurrence  of any other event  giving  rise to the  payment  subject to an
indemnity,  or (ii) if the party in control of the issue under Section 6.8(e)(4)
determines  to  contest  the  issue,  the  earlier  of the  signing of a closing
agreement  or  settlement  agreement  or any other  similar  agreement  with the
relevant tax  authorities,  the receipt of a  deficiency  notice with respect to
which the period for filing a petition with the relevant court has expired, or a
decision of any court of competent  jurisdiction  which is not subject to appeal
or as to which the time for appeal has expired.

      (4) Tax Contest. (i) GPU and Buyer shall notify the other party in writing
within 30 days of receipt of written  notice of any  pending or  threatened  tax
examination,  audit or  other  administrative  or  judicial  proceeding  (a "Tax
Contest")  that could  reasonably  be expected  to result in an  indemnification
obligation  under this  Section  6.8(e) of such  other  party  pursuant  to this
Section  6.8(e).  If the  recipient  of such  notice of a Tax  Contest  fails to
provide  such  notice  to  the  other  party,   it  shall  not  be  entitled  to
indemnification  for any Taxes arising in connection with such Tax Contest,  but
only to the extent,  if any,  that such  failure or delay  shall have  adversely
affected the indemnifying party's ability to defend against,  settle, or satisfy
any action, suit or proceeding against it, or any damage, loss, claim, or demand
for which the indemnified party is entitled to indemnification hereunder.

      (ii) If a Tax  Contest  relates  to any  period  ending on or prior to the
Closing  Date or to any Taxes for  which  GPU is liable in full  hereunder,  GPU
shall at its expense control the defense and settlement of such Tax Contest.  If
such Tax contest  relates to any period  beginning  after the Closing Date or to
any Taxes for which  Buyer is liable in full  hereunder,  Buyer shall at its own
expense control the defense and settlement of such Tax Contest. The party not in
control of the  defense  shall have the right to observe  the conduct of any Tax
Contest at its expense, including through its own counsel and other professional
experts. Buyer and GPU shall jointly represent Genco in any Tax Contest relating
to a Straddle Period, and fees and expenses related to such representation shall
be paid equally by Buyer and GPU.

      (iii) Notwithstanding  anything to the contrary in section  6.8(e)(4)(ii),
to the extent that an issue raised in any Tax Contest controlled by one party or
jointly  controlled could materially affect the liability for Taxes of the other
party,  the controlling  party shall not, and neither party in the case of joint
control shall, enter into a final settlement without the

                                      62






consent of the other party,  which  consent  shall not be  reasonably  withheld.
Where a party  withholds  its  consent to any final  settlement,  that party may
continue or initiate further proceedings,  at its own expense, and the liability
of the  party  that  wished  to  settle  (as  between  the  consenting  and  the
non-consenting  party) shall not exceed the  liability  that would have resulted
from the proposed final  settlement  including  interest,  additions to Tax, and
penalties that have accrued at that time),  and the  non-consenting  party shall
indemnify the consenting party for such Taxes.

            Notwithstanding  any  provision of this  Agreement to the  contrary,
this  Section 6.8 shall  survive for the duration of any  applicable  limitation
periods.


      (5) Tax Sharing Agreements.  Any Tax sharing agreement to which Genco is a
party shall be deemed  terminated with respect to Genco on, and effective as of,
the Closing Date, and no Person shall have any rights or obligations  under such
Tax sharing  agreement with respect to Genco after such  termination;  provided,
however,  that the GPU  Intercompany  Tax allocation  Agreement  shall remain in
effect  with  respect  to Genco in order to  determine  the  portion  of GPU and
Sellers'  Tax  liabilities  attributable  to Genco,  and to be paid to GPU under
Section 6.8(e)(2)(ii) for the post-Closing Date portion of the Straddle Period.

      (f) Disputes.  In the event that a dispute arises  between  Sellers or GPU
and  Buyer  as to the  amount  of  Taxes,  or  indemnification,  whether  or not
attributable  to Genco,  or the amount of any allocation of Purchase Price under
Section 3.4 or 6.8(e)(1)(ii)  hereof, the parties shall attempt in good faith to
resolve  such  dispute,  and  any  agreed  upon  amount  shall  be  paid  to the
appropriate  party.  If such  dispute is not  resolved 30 days  thereafter,  the
parties  shall  submit  the  dispute  to the  Independent  Accounting  firm  for
resolution,  which  resolution  shall be final,  conclusive  and  binding on the
parties.  Notwithstanding  anything in this Agreement to the contrary,  the fees
and expenses of the  Independent  Accounting Firm in resolving the dispute shall
be borne  equally  by Seller or GPU,  as  applicable,  and  Buyer.  Any  payment
required  to be  made  as a  result  of the  resolution  of the  dispute  by the
Independent Accounting firm shall be made within ten days after such resolution,
together with any interest  determined by the Independent  Accounting Firm to be
appropriate.

      (g) Cooperation.  Buyer and GPU shall (and Buyer and GPU shall cause Genco
to)  cooperate  fully,  as and to the extent  reasonably  requested by the other
Party, in connection with the

                                      63






filing of Tax Returns  pursuant to this  Agreement and any audit,  litigation or
other  proceeding  with respect to Taxes.  Such  cooperation  shall  include the
retention  and (upon the other  Party's  request)  the  provision of records and
information which are reasonably relevant to any such audit, litigation or other
proceeding and making  employees (to the extent such employees were  responsible
for the preparation,  maintenance or interpretation of information and documents
relevant  to Tax  matters  or to the extent  required  as  witnesses  in any Tax
proceedings),  available on a mutually  convenient  basis to provide  additional
information  and  explanation of any material  provided  hereunder.  The Parties
agree (i) to retain,  and (in the case of Buyer) to cause  Genco to retain,  all
books and records with respect to Tax matters pertinent to Genco relating to any
taxable  period  beginning  before the Closing  Date until six months  after the
expiration of the statute of limitations  (and, to the extent  notified by Buyer
or Sellers,  any extensions  thereof) of the respective taxable periods,  and to
abide  by all  record  retention  obligations  imposed  by law  or  pursuant  to
agreements  entered into with any taxing  authority,  and (ii) to give the other
Party reasonable written notice prior to transferring,  destroying or discarding
any such  books and  records  and,  if the  other  Party so  requests,  Buyer or
Sellers,  as the case may be, shall allow the other Party to take  possession of
such books and records.

      Buyer,  Genco and GPU  further  agree,  upon  request,  to use their  best
efforts  to obtain  any  certificate  or other  document  from any  governmental
authority  or any  other  Person  as may be  necessary  to  mitigate,  reduce or
eliminate  any Tax that could be imposed  (including,  but not  limited to, with
respect to the transactions contemplated hereby).

      At GPU's  request,  Buyer will cause Genco to make and/or join with GPU in
making  after  Closing any election of GPU's  consolidated  group for which each
member's  consent is required,  if the making of such  election  does not have a
material adverse impact on Buyer or Genco for any post-acquisition Tax period.

      6.9 Advice of  Changes.  Prior to the  Closing,  each Party will  promptly
advise the other in writing with respect to any matter  arising after  execution
of this Agreement of which that Party obtains  Knowledge and which,  if existing
or occurring at the date of this  Agreement,  would have been required to be set
forth in this Agreement,  including any of the Schedules hereto.  Sellers may at
any time notify Buyer of any development causing a breach of any of its or GPU's
representations  and warranties in Article IV or IVA. Unless Buyer has the right
to terminate  this  Agreement  pursuant to Section 9.1(f) below by reason of the
developments and exercises that right within the period of

                                      64






fifteen (15) days after such right accrues,  the written notice pursuant to this
Section  6.9 will be  deemed  to have  amended  this  Agreement,  including  the
appropriate  Schedule,  to have  qualified the  representations  and  warranties
contained in Article IV or IVA above, and to have cured any misrepresentation or
breach of warranty that otherwise might have existed  hereunder by reason of the
development.

      6.10  Employees.

      (a) At least 90 days prior to the Closing Date (but in no case sooner than
ninety (90) days after the date hereof), Buyer shall provide Sellers with notice
of its Union Employee staffing level requirements  (which Buyer may determine in
its sole  discretion),  listed by  classification  and  operation,  and shall be
required to make reasonable  efforts to offer employment to that number of Union
Employees necessary to satisfy such staffing level requirements. As used herein,
"Union  Employees"  means  such  employees  of  Sellers  who are  covered by the
Collective Bargaining Agreement as defined in Section 6.10(d) below, and who are
listed  in,  or  whose  employment  responsibilities  are  listed  in,  Schedule
6.10(a)(i) as "Plant Employees" or "Dedicated  Support Staff" as associated with
the Plants  purchased by Buyer,  and those Union Employees who are listed in, or
whose employment responsibilities are listed in, Schedule 6.10(a)(ii) as "Mobile
Maintenance" or "Corporate  Support".  Any offers of employment shall be made at
least 60 days prior to the Closing Date. In each classification, Union Employees
shall be so offered employment in order of their seniority.

      (b) Buyer is also entitled to determine its  Non-Union  Employee  staffing
level  requirements in its sole discretion,  and make reasonable efforts to make
offers of  employment  with  Buyer or any of its  Affiliates,  effective  on the
Closing Date, to Non-Union  Employees  consistent with such staffing levels.  As
used herein, " Non-Union  Employees"  means such salaried  employees of Sellers,
Genco, GPUN or GPUS who are listed in, or whose employment  responsibilities are
listed in, Schedule 6.10(b) as "Plant  Employees" or "Dedicated  Support Staff",
and those Non-Union  Employees listed in, or whose  employment  responsibilities
are listed  in,  Schedule  6.10(a)(ii)  as "Mobile  Maintenance"  or  "Corporate
Support".  Any offers of employment shall be made at least sixty (60) days prior
to the Closing  Date.  Each  person who becomes  employed by Buyer or any of its
Affiliates  pursuant to Section 6.10(a) or (b) (whether pursuant to a Qualifying
Offer  or  otherwise)  shall be  referred  to  herein  as a  "Transferred  Union
Employee" or "Transferred Non-Union Employee", respectively. At least forty-five
(45) days prior to the Closing Date,  Buyer shall provide  Seller with notice of
those Non-Union Employees to whom

                                      65






it made a Qualifying Offer. As used herein, the term "Qualifying Offer" means an
offer of employment at an annual level of  compensation  that is at least 85% of
the employee's current total annual cash compensation (consisting of base salary
and target incentive bonus) at the time the offer is made. Schedule 6.10(b) sets
forth, for each of the Non-Union  Employees  listed therein,  his or her current
base salaries and target incentive bonuses.

      (c) All offers of  employment  made  pursuant to  Sections  6.10(a) or (b)
shall be made in accordance  with all applicable  laws and  regulations,  and in
addition,  for Union  Employees,  in  accordance  with  seniority  and all other
applicable provisions of the Collective Bargaining Agreement.

      (d) Schedule 6.10(d) sets forth the collective bargaining  agreement,  and
amendments thereto, to which each Seller is a party with the Union in connection
with the Purchased Assets ("Collective Bargaining Agreement"). Transferred Union
Employees  shall retain their seniority and receive full credit for service with
Sellers in connection  with  entitlement  to vacation and all other benefits and
rights under the Collective  Bargaining  Agreement and under each  compensation,
retirement  or other  employee  benefit  plan or program  Buyer is  required  to
maintain for Transferred Union Employees  pursuant to the Collective  Bargaining
Agreement.  With respect to  Transferred  Union  Employees,  effective as of the
Closing Date,  Buyer shall assume the  Collective  Bargaining  Agreement for the
duration of its term as it relates to Transferred Union Employees to be employed
at the Plants in positions  covered by the Collective  Bargaining  Agreement and
shall  thereafter  comply with all applicable  obligations  under the Collective
Bargaining  Agreement.  Consistent  with its  obligations  under the  Collective
Bargaining  Agreement and applicable  laws, Buyer shall be required to establish
and  maintain  a  pension  plan and  other  employee  benefit  programs  for the
Transferred  Union  Employees  for the  duration  of the term of the  Collective
Bargaining  Agreement which are  substantially  equivalent to Seller's plans and
programs in effect for the Transferred Union Employees  immediately prior to the
Closing Date (the "Sellers'  Plans"),  and which provide at least the same level
of benefits or coverage as do Sellers'  Plans for the duration of the Collective
Bargaining  Agreement.  Buyer  further  agrees  to  recognize  the  Union as the
collective bargaining agent for the applicable Transferred Union Employees.

      (e)  Transferred   Non-Union  Employees  shall  be  eligible  to  commence
participation in welfare benefit plans of Buyer or its Affiliates as may be made
available by Buyer (the "Replacement Welfare Plans").  Buyer shall (i) waive all
limitations as to pre-existing condition exclusions and waiting periods with

                                      66






respect to the Transferred  Non-Union  Employees  under the Replacement  Welfare
Plans,  other than, but only to the extent of,  limitations  or waiting  periods
that were in effect  with  respect to such  employees  under the  welfare  plans
maintained by Sellers, Genco, GPUN or GPUS or their Affiliates and that have not
been  satisfied  as of the  Closing  Date,  and (ii)  provide  each  Transferred
Non-Union  Employee with credit for any copayments and deductibles paid prior to
the Closing Date in  satisfying  any  deductible or  out-of-pocket  requirements
under  the  Replacement  Welfare  Plans (on a  pro-rata  basis in the event of a
difference in plan years).

      (f) Transferred  Non-Union Employees shall be given credit for all service
with  Sellers,  Genco,  GPUN,  GPUS and  their  Affiliates  under  all  deferred
compensation,    profit-sharing,    401(k),   retirement   pension,    incentive
compensation,  bonus, fringe benefit and other employee benefit plans,  programs
and  arrangements  of Buyer  ("Buyer  Benefit  Plans")  in which they may become
participants.  The service  credit so given shall be for purposes of eligibility
and  vesting,  but shall not be for  purposes of level of  benefits  and benefit
accrual except to the extent that the Buyer Benefit Plans otherwise provide.

      (g) To the extent allowable by law, Buyer shall take any and all necessary
action to cause the  trustee of any  defined  contribution  plan of Buyer or its
Affiliates in which any Transferred  Employee  becomes a participant to accept a
direct  "rollover"  of all or a portion of said  employee's  "eligible  rollover
distribution"  within  the  meaning  of  Section  402 of the  Code  from the GPU
Companies  Employee  Savings  Plan  for  Non-Bargaining  Employees  or from  the
Employee Savings Plan for Bargaining Unit Employees  maintained by JCP&L, Met-Ed
or  Penelec  (the  "Sellers'  Savings  Plans")  if  requested  to do  so by  the
Transferred  Employee.  Buyer  agrees  that the  property so rolled over and the
assets so  transferred  may  include  promissory  notes  evidencing  loans  from
Sellers'  Savings Plans to Transferred  Employees that are outstanding as of the
Closing Date.  However,  except as otherwise  provided in Section  6.10(d),  any
defined  contribution plan of Buyer or its Affiliates  accepting such a rollover
or transfer  shall not be required to make any further loans to any  Transferred
Employee after the Closing Date.

      (h) Buyer  shall pay or  provide to  Transferred  Employees  the  benefits
described in  subparagraphs  (i),  (ii) and (iii) of this Section  6.10(h),  and
shall  reimburse  Sellers for the cost of the benefits that Sellers' or Sellers'
Affiliates will provide to Union Employees and Non-Union Employees in accordance
with subparagraph (iv) of this Section 6.10(h).

                                      67






                  (i) Buyer  shall make a  transition  incentive  payment in the
      amount of $2,500 to each Transferred Union Employee. Payment shall be made
      as soon as  practicable  after,  but in any  event no  later  than 60 days
      following, the Closing Date.

                  (ii) In the case of each Transferred Non-Union Employee who is
      initially  assigned by Buyer to a principal place of work that is at least
      50 miles  farther from the  employee's  principal  residence  than was his
      principal  place of work  immediately  prior to the  Closing  Date and who
      relocates his or her principal residence to the vicinity of his or her new
      principal place of work within 12 months following the Closing Date, Buyer
      shall reimburse the employee for all "moving  expenses" within the meaning
      of Section  217(b) of the Code  incurred by the employee and other members
      of his or her  household  in  connection  with  such  relocation,  up to a
      maximum  aggregate  amount of $5,000.  Claims for  reimbursement  for such
      expenses shall be filed in accordance with such  procedures,  and shall be
      accompanied by such substantiation of the expenses for which reimbursement
      is sought, as Buyer may reasonably  request.  All claims for reimbursement
      shall be processed,  and qualifying expenses shall be reimbursed,  as soon
      as practicable  after,  but in any event no later than 60 days  following,
      the date on which the employee's  claim for  reimbursement is submitted to
      Buyer.

                  (iii) Buyer shall provide the severance  benefits described in
      Section  1 of  Schedule  6.10(h)  to  each  Transferred  Employee  who  is
      "Involuntarily  Terminated"  (as defined below) (a) within 12 months after
      the Closing Date or (b), in the case of any Transferred Non-Union Employee
      who had attained age 50 and had completed at least 10 Years of Service (as
      defined in Section 1(c) of Schedule 6.10(h)) prior to the Closing Date, on
      or any time prior to June 30, 2004.  For purposes of this Section  6.10(h)
      and  Schedule  6.10(h),  a  Transferred   Employee  shall  be  treated  as
      "Involuntarily  Terminated" if his or her employment with Buyer and all of
      its  Affiliates is terminated  by Buyer or any of its  Affiliates  for any
      reason  other  than for  cause or  disability.  Buyer  shall  require  any
      Transferred  Employee who is Involuntarily  Terminated,  as a condition to
      receiving the severance  benefits described in Section 1(b), (c), (d), (e)
      and (f) of  Schedule  6.10(h),  to  execute  a release  of claims  against
      Sellers, Genco, GPUN or GPUS, as applicable,  and all of their Affiliates,
      and Buyer, in such form as Buyer and Sellers shall agree upon.


                                      68





                  (iv) At the Closing or as soon thereafter as practicable,  but
      in any event no later than 60 days following the Closing Date, Buyer shall
      pay to Sellers,  in  addition to all other  amounts to be paid by Buyer to
      Sellers hereunder,  an amount equal to Buyer's Allocable Share (as defined
      below) of the aggregate estimated cost that the Sellers or any of Sellers'
      Affiliates will or may incur in providing the severance,  pension,  health
      care and group  term life  insurance  benefits  described  in Section 2 of
      Schedule  6.10(h) to the Union Employees and Non-Union  Employees  therein
      described (collectively the "Termination Benefits"). The estimated cost of
      such benefits shall be calculated by the actuarial firm regularly  engaged
      to provide  actuarial  services to the GPU Companies with respect to their
      pension,  health care and life  insurance  plans,  and shall be determined
      using the same  assumptions as to mortality,  turnover,  interest rate and
      other actuarial assumption as used by such firm in determining the cost of
      benefits  under the GPU  Companies'  pension,  health  and group term life
      insurance  plans for  purposes  of their most  recently  issued  financial
      statements  prior to the Closing  Date.  For  purposes  of the  foregoing,
      Buyer's  "Allocable  Share" shall be  calculated  as set forth in Schedule
      6.10(h)(iv).

      (i) Buyer shall not be  responsible  for any payments  required  under any
voluntary  early  retirement  plan,  program or arrangement  offered by Sellers,
Genco,  GPUN or GPUS in connection  with the transfer of the  Purchased  Assets.
Within  thirty  (30)  days  following  the last day that any Union  Employee  or
Non-Union Employee may elect to participate in any such plan offered by Sellers,
Genco,  GPUN or  GPUS,  Sellers  shall  provide  Buyer  with a list of all  such
employees who have so elected.

      (j) Sellers shall be  responsible,  with respect to the Purchased  Assets,
for performing and  discharging  all  requirements  under the WARN Act and under
applicable  state and local laws and  regulations  for the  notification  of its
employees  of any  "employment  loss"  within the  meaning of the WARN Act which
occurs prior to the Closing Date.

      (k) Buyer  shall  not be  responsible  for  extending  COBRA  continuation
coverage to any employees and former employees of Sellers,  Genco, GPUN or GPUS,
or to any qualified  beneficiaries of such employees and former  employees,  who
become or became  entitled to COBRA  continuation  coverage  before the Closing,
including those for whom the Closing occurs during their COBRA election period.

      (l)   Sellers or Sellers' Affiliates shall pay to all

                                      69






Transferred   Employees,   all   compensation,   bonus,   vacation  and  holiday
compensation,  pension, profit sharing and other deferred compensation benefits,
workers'  compensation,  or other employment benefits to which they are entitled
under the terms of the applicable compensation or benefit programs at such times
as are provided therein.

      (m) Individuals who are otherwise "Union  Employees" as defined in Section
6.10(a) or "Non-Union  Employees"  as defined in Section  6.10(b) but who on any
date are not  actively  at work due to a leave of absence  covered by the Family
and Medical Leave Act ("FMLA"), or due to any other authorized leave of absence,
shall nevertheless be treated as "Union Employees" or as "Non-Union  Employees",
as the case may be, on such  date if they are able (i) to return to work  within
the  protected  period  under the FMLA or such other  leave  (which in any event
shall not extend more than twelve (12) weeks after the Closing Date),  whichever
is applicable,  and (ii) to perform the essential  functions of their jobs, with
or without a reasonable accommodation.

      (n) Effective as of the day  immediately  preceding the Closing Date,  GPU
shall (i) cause Genco to terminate or to transfer to one or more  Affiliates  of
GPU, the  employment of any  individual in the employ of Genco on such preceding
day who will not be a Transferred  Employee  immediately  following the Closing,
and (ii) cause all Benefit Plans  maintained by Genco,  and all  liabilities and
obligations  of Genco with  respect to such  plans,  to be  transferred  to, and
assumed by, one or more Affiliates of GPU other than Genco.

      6.11  Risk of Loss.

      (a) From the date hereof  through the  Closing  Date,  all risk of loss or
damage  to the  property  included  in the  Purchased  Assets  shall be borne by
Sellers,  other than loss or damage caused by the acts or negligence of Buyer or
any Buyer  Representative,  which loss or damage shall be the  responsibility of
Buyer.

      (b) If,  before the  Closing  Date,  all or any  portion of the  Purchased
Assets is (i) taken by eminent  domain or is the subject of a pending or (to the
Knowledge of Sellers)  contemplated  taking which has not been  consummated,  or
(ii) damaged or destroyed  by fire or other  casualty,  such Seller shall notify
Buyer promptly in writing of such fact,  and (x) in the case of a  condemnation,
such Seller  shall  assign or pay, as the case may be, any  proceeds  thereof to
Buyer at the Closing and (y) in the case of a casualty, such Seller shall either
restore the damage or assign the insurance proceeds therefor (and pay the amount
of any deductible and/or self-insured amount in respect of such
                                      70





casualty) to Buyer at the Closing.  Notwithstanding  the above, if such casualty
or loss results in a Material Adverse Effect,  Buyer and Sellers shall negotiate
to settle  the loss  resulting  from such  taking  (and such  negotiation  shall
include, without limitation,  the negotiation of a fair and equitable adjustment
to the Purchase Price).  If no such settlement is reached within sixty (60) days
after  Sellers  have  notified  Buyer of such  casualty  or loss,  then Buyer or
Sellers may terminate this Agreement pursuant to Section 9.1(h). In the event of
damage or  destruction  which  Sellers  elect to restore,  Sellers will have the
right to postpone  the  Closing  for up to four (4) months.  Buyer will have the
right to inspect and observe,  or have its  representatives  inspect or observe,
all repairs necessitated by any such damage or destruction.

      6.12 Additional  Covenants of Buyer.  Notwithstanding  any other provision
hereof,  Buyer covenants and agrees that, after the Closing Date, Buyer will not
make any  modifications  to the Purchased Assets or take any action which in and
of itself,  results in a loss of the  exclusion  of  interest  on the  Pollution
Control  Revenue  Bonds  issued on  behalf of  Sellers  in  connection  with the
Purchased Assets from gross income for federal income purposes under Section 103
of the Code. Actions with respect to the Purchased Assets shall not constitute a
breach by the Buyer of this Section  6.12 in the  following  circumstances:  (i)
Buyer ceases to use or decommissions any of the Purchased Assets or subsequently
repowers such Purchased  Assets that are no longer used or  decommissioned  (but
does not hold such Purchased  Assets for sale);  (ii) Buyer acts with respect to
the  Purchased  Assets in order to comply  with  requirements  under  applicable
federal,  state or local  environmental  or other laws or regulations;  or (iii)
Buyer acts in a manner the  Sellers  (i.e.  a  reasonable  private  provider  of
electricity  of similar  stature as Seller)  would have acted during the term of
the Pollution Control Revenue Bonds (including, but not limited to, applying new
technology). In the event Buyer acts or anticipates acting in a manner that will
cause a loss of the exclusion of interest on the Pollution Control Revenue Bonds
from gross  income for  federal  income tax  purposes,  at the request of Buyer,
Sellers shall take any remedial  actions  permitted under the federal income tax
law that would prevent a loss of such inclusion of interest from gross income on
the Pollution Control Revenue Bonds. Buyer further covenants and agrees that, in
the event that Buyer transfers any of the Purchased  Assets,  Buyer shall obtain
from its  transferee  a covenant  and  agreement  that is  analogous  to Buyer's
covenant and agreement pursuant to the immediately  preceding sentence,  as well
as a covenant  and  agreement  that is analogous  to that of this  sentence.  In
addition, Buyer shall not, without 60 days advanced written notice to Seller (to
the extent practicable under the

                                      71






circumstances), take any action which would result in (x) a change in the use of
the assets  financed  with the Pollution  Revenue  Control Bonds from the use in
which  such  assets  were  originally  intended,  or (y) a sale of  such  assets
separate  from the  generating  assets to which they  relate,  provided  that no
notice is required  of the events set forth in clauses (i) (ii) or (iii)  above.
This covenant shall survive  Closing and shall continue in effect so long as the
pollution control bonds remain outstanding.

            6.13 Name Change. At or prior to the Closing,  GPU shall cause Genco
to amend its certificate of incorporation to change its corporate name to delete
"GPU" therefrom and to adopt such name as Buyer may advise GPU in writing.

with by Sellers and GPU on or prior to the Closing Date;

      (e) The  representations  and  warranties  of Sellers and GPU set forth in

                  (i)  Each  of   Sellers   and  GPU  is  a   corporation   duly
      incorporated,  validly existing and in good standing under the laws of its
      state of  incorporation  and has the corporate power and authority to own,
      lease and operate its material  assets and  properties and to carry on its
      business as is now conducted, and to execute and deliver the Agreement and

                  (ii) The Agreement and each Ancillary Agreement have been duly
      and validly  executed and  delivered by each Seller and GPU, as applicable
      and  constitutes a legal,  valid and binding  agreement of each Seller and
      GPU, as applicable,  enforceable in accordance with its terms, except that
      such enforceability may be limited by applicable  bankruptcy,  insolvency,
      fraudulent  conveyance,  reorganization,  moratorium or other similar laws
      affecting or relating to  enforcement of creditors'  rights  generally and
      general  principles  of  equity  (regardless  of  whether  enforcement  is
      considered in a proceeding at law or in equity);

                  (iii) The execution, delivery and performance of the Agreement
      and each  Ancillary  Agreement by each Seller and GPU, as applicable  does
      not (A) conflict with the Certificate of  Incorporation  or Bylaws of such
      Seller  or GPU or (B) to the  knowledge  of  such  counsel,  constitute  a
      violation of or default under those agreements or
                                      73





      instruments set forth on a Schedule attached to the opinion and which have
      been  identified  to such counsel as all the  agreements  and  instruments
      which are material to the  business or financial  condition of each Seller
      and GPU;

                  (iv)  The  Bill  of  Sale,  the  deeds,   the  Assignment  and
      Assumption Agreement and other transfer  instruments  described in Section
      3.6 have been  duly  executed  and  delivered  and are in  proper  form to
      transfer  to Buyer such title as was held by such  Seller and GPU,  in the
      case of the Genco Stock to the Purchased Assets;

                  (v) No consent or approval of,  filing with, or notice to, any
      Governmental Authority is necessary for the execution and delivery of this
      Agreement by the Sellers and GPU, or the  consummation  by Sellers and GPU
      of the  transactions  contemplated  hereby,  other than (i) such consents,
      approvals,  filings or notices set forth in Schedule  4.3(b) or which,  if
      not obtained or made, will not prevent the Sellers and GPU from performing
      their material  obligations  hereunder and (ii) such consents,  approvals,
      filings  or  notices  which  become  applicable  to  Sellers or GPU or the
      Purchased  Assets as a result of the specific  regulatory  status of Buyer
      (or  any  of its  Affiliates)  or as a  result  of any  other  facts  that
      specifically  relate to the business or  activities in which Buyer (or any
      of its Affiliates) is or proposes to be engaged.

                  (vi) The Genco  Stock is owned of  record by GPU,  and to such
      counsel's   knowledge,   beneficially   by  GPU  free  and  clear  of  all
      Encumbrances. The Genco Stock has been duly authorized and validly issued,
      and is fully paid and non-assessable. There are no other authorized shares
      of  capital  stock of Genco  other  than the 2500  shares of common  stock
      comprising the Genco Stock.  None of the shares comprising the Genco Stock
      has been issued in violation  of, or is subject to, any  statutory  or, to
      such counsel's  knowledge,  other  Restrictive Third Party Rights. To such
      counsel's knowledge,  (i) there are no outstanding  securities convertible
      into or  exchangeable  for the capital  stock of Genco or any  restrictive
      covenants  applicable  to the Genco Stock,  and (ii) neither GPU nor Genco
      has any obligation,  contingent or otherwise,  to issue, sell, repurchase,
      redeem or otherwise  acquire any of the Genco Stock or other capital stock
      of Genco or any equity or debt securities of Genco.  Upon the consummation
      of the  transactions  contemplated in the Agreement,  Buyer will have good
      and valid title to the Genco Stock, to such counsel's knowledge,  free and
      clear of all Encumbrances and Restrictive Third Party Rights.
                                      74





      In rendering the foregoing opinion, Sellers' and GPU's counsel may rely on
opinions of counsel as to local laws reasonably acceptable to Buyer.

      (h) Sellers and GPU shall have  delivered,  or caused to be delivered,  to
Buyer at the Closing, Sellers' and GPU's closing deliveries described in Section
3.6.

the extent  necessary,  to own and  operate the Plants in  accordance  with past
emissions and operating  practices,  except for those Permits and  Environmental
Permits, the absence of which would not in the aggregate have a Material Adverse
Effect.

      (m) Seller's Required Regulatory  Approvals shall contain no conditions or
terms which would result in a Material Adverse Effect.

      (n) Neither the Real  Property nor any portion  thereof shall be part of a
tax lot which includes any real property and/or  buildings,  facilities or other
improvements other than that which comprises the Real Property.

      (o) No  Site,  or  any  portion  thereof  shall  be  subject  to a  zoning
classification or classifications,  rule or regulation, or a variance or special
exception, which, individually or in the aggregate, does not permit such Site or
any portion  thereof to be used as the same (i) is currently used for generation
purposes or (ii) was historically used for generation purposes while under

                                      75






Seller's current ownership or the ownership of any Affiliate thereof, unless the
failure  of such Site of any  portion  thereof  to be zoned to permit  such use,
shall not result in a Material Adverse Effect.

GPU to  effect  the sale of the  Purchased  Assets  and the  other  transactions
contemplated  by this Agreement  shall be subject to the fulfillment at or prior

                  (i) Buyer is a Delaware  corporation  duly organized,  validly
      existing  and  in  good  standing  under  the  laws  of the  state  of its

      such counsel, constitute
                                      77

      will not prevent Buyer from  performing its respective  obligations  under
      the Agreement, the Ancillary Agreements and Guaranty.

(j) Buyer shall have  delivered,  or caused to be  delivered,  to Sellers at the
Closing, Buyer's closing deliveries described in Section 3.7.

      7.3   Zoning Condition Adjustments.

            (a) In the  event  that any Site or any  portion  thereof,  shall be
subject to a zoning  classification or classifications,  rule or regulation,  or
variance or special  exception,  which does not permit or otherwise restrict the
Site or any portion  thereof,  to be used as the same (i) is currently  used for
generation  purposes or (ii) was historically used for generation purposes while
under Seller's current  ownership or the ownership of any Affiliate  thereof for
generation  purposes,  and if such failure  shall  result in a material  adverse
effect on the use of such Site for generating  purposes as currently used (or as
so historically  used),  then, in such event, Buyer may, prior to the Closing on
written  notice to the Seller,  exclude from the Purchased  Assets such Site and
the  Purchased  Assets  related to such Site.  Buyer and Seller shall  thereupon
negotiate a fair and equitable adjustment to the Purchase Price or, failing such
agreement  within 30 days,  the  adjustment  shall be determined by appraisal in
accordance  with Section  7.3(b),  the cost of which shall be shared  equally be
Buyer and Seller.

            (b) The Parties shall select an Appraiser (as defined  below) within
30 days of the expiration of the 30 day period referred to in Section 7.3(a). In
the event the Parties cannot within such period agree on a single Appraiser, the
Parties shall each within 15 days select a separate Appraiser, and such
                                      78





Appraisers  shall  within 15 days,  later  designate  a third  Appraiser  to act
hereunder.  The Appraiser shall be instructed to provide a written report of the
appropriate reduction of the Purchase Price to be allocated to the excluded Site
(and associated Purchased Assets). Each of the Parties may submit such materials
and  information  to the  Appraiser  as it deems  appropriate  and shall use its
Commercially  Reasonable  Efforts to cause the  Appraiser to render its decision
within 60 days after the matter has been submitted to it. The  determination  of
the  Appraiser  shall be final  and  binding  on the  Parties.  As used  herein,
"Appraiser"  means an individual who has a minimum of ten (10) years of relevant
experience in valuing electric generation  facilities and has an MAI designation
of the Appraisal Institute.

            (c)  Buyer  agrees to use  Commercially  Reasonable  Efforts  at its
expense  and  in  consultation  with  Seller  to  mitigate  any  adverse  zoning
restrictions  which could cause a failure of the  Closing  condition  in Section
7.1(o), or require a Purchase Price adjustment under this Section 7.3, including
by seeking a re-zoning or zoning variance of the applicable Site.


                                  ARTICLE VIII

                                 INDEMNIFICATION

      8.1 Indemnification.

      (a)  Buyer  shall  indemnify,  defend  and hold  harmless  Sellers,  their
officers,  directors,  employees,  shareholders,  Affiliates and agents (each, a
"Sellers'  Indemnitee")  from and against any and all  claims,  demands,  suits,
losses,  liabilities,   damages,  obligations,   payments,  costs  and  expenses
(including,  without limitation,  the costs and expenses of any and all actions,
suits, proceedings, assessments, judgments, settlements and compromises relating
thereto  and  reasonable   attorneys'  fees  and  reasonable   disbursements  in
connection  therewith)  (each, an  "Indemnifiable  Loss"),  asserted  against or
suffered by any Sellers'  Indemnitee  relating to, resulting from or arising out
of (i) any breach by Buyer of any covenant or  agreement  of Buyer  contained in
this Agreement or the representations and warranties  contained in Sections 5.1,
5.2 and 5.3, (ii) the Assumed  Liabilities,  (iii) any loss or damages resulting
from or arising out of any  Inspection,  or (iv) any Third Party Claims  against
Sellers'  Indemnitee  arising out of or in connection with Buyer's  ownership or
operation of the Plants and other Purchased  Assets on or after the Closing Date
(other than Third Party  Claims  which arise out of acts by Buyer  permitted  by
Section 6.12 hereof).

                                      79





      (b) Each  Seller  shall  indemnify  defend and hold  harmless  Buyer,  its
officers,  directors,  employees,  shareholders,  Affiliates and agents (each, a
"Buyer  Indemnitee") from and against any and all Indemnifiable  Losses asserted
against or suffered  by any Buyer  Indemnitee  relating  to,  resulting  from or
arising out of (i) any breach by such Seller of any  covenant  or  agreement  of
such Seller  contained in this Agreement or the  representations  and warranties
contained in Sections 4.1, 4.2 and 4.3, (ii) the Excluded Liabilities other than
Section  2.4(o)  or  2.4(c)  (relating  to  the  Operating  Agreements),   (iii)
noncompliance  by Sellers  with any bulk sales or  transfer  laws as provided in
Section 10.11, or (iv) any Third Party Claims against a Buyer Indemnitee arising
out of or in  connection  with  Sellers'  ownership or operation of the Excluded
Assets on or after  the  Closing  Date.  GPU shall  indemnify,  defend  and hold
harmless  each  Buyer  Indemnitee  from and  against  any and all  Indemnifiable
Losses,  asserted  against or  suffered  by any Buyer  Indemnitee  relating  to,
resulting  from or arising out of any breach by GPU of any covenant or agreement
of GPU  contained  in this  Agreement,  the  Excluded  Liabilities  set forth in
Section  2.4(o)  and  2.4(c)  (relating  to  the  Operating  Agreements)  or the
representations and warranties contained in Sections 4A.1, 4A.2 and 4A.3.

      (c) Each  Party,  for  itself  and on  behalf of its  Representatives  and
Affiliates,  does hereby release,  hold harmless and forever discharge the other
party, its Representatives and Affiliates, from any and all Indemnifiable Losses
of any  kind or  character,  whether  known or  unknown,  hidden  or  concealed,
resulting  from or arising out of any  Environmental  Condition  or violation of
Environmental  Law  relating to the  Purchased  Assets  provided  that  Sellers'
release  of Buyer  shall not extend to any of Buyer's  Assumed  Liabilities  set
forth in Section 2.3, and provided further that Buyer's release of Sellers shall
not extend to any of Sellers'  Excluded  Liabilities  set forth in Section  2.4.
Subject to the  foregoing  proviso,  each party hereby waives any and all rights
and benefits  with respect to such  Indemnifiable  Losses that it now has, or in
the future  may have  conferred  upon it by virtue of any  statute or common law
principle  which provides that a general release does not extend to claims which
a party does not know or suspect to exist in its favor at the time of  executing
the release,  if knowledge of such claims would have  materially  affected  such
party's  settlement  with the  obligor.  In this  connection,  each party hereby
acknowledges that it is aware that factual matters,  now unknown to it, may have
given or may  hereafter  give rise to  Indemnifiable  Losses that are  presently
unknown,  unanticipated and unsuspected, and it further agrees that this release
has  been  negotiated  and  agreed  upon  in  light  of  that  awareness  and it
nevertheless hereby


                                      80





intends to release the other party and its  Representatives  and Affiliates from
the Indemnifiable Losses described in the first sentence of this paragraph.

      (d) Notwithstanding anything to the contrary contained herein:

                  (i) Any Person entitled to receive  indemnification under this
      Agreement (an "Indemnitee")  shall use Commercially  Reasonable Efforts to
      mitigate all losses,  damages and the like relating to a claim under these
      indemnification  provisions,  including  availing  itself of any defenses,
      limitations,  rights of  contribution,  claims  against  third Persons and
      other rights at law or equity.  The Indemnitee's  Commercially  Reasonable
      Efforts shall include the  reasonable  expenditure of money to mitigate or
      otherwise   reduce  or   eliminate   any  loss  or   expenses   for  which
      indemnification would otherwise be due, and the Indemnitor shall reimburse
      the Indemnitee for the Indemnitee's reasonable expenditures in undertaking
      the mitigation.

                  (ii) Any  Indemnifiable  Loss  shall be net of (A) the  dollar
      amount of any  insurance  or other  proceeds  actually  receivable  by the
      Indemnitee  or any of its  Affiliates  with  respect to the  Indemnifiable
      Loss,  but shall not take into  account  any  income tax  benefits  to the
      Indemnitee  or  any  Income  Taxes  attributable  to  the  receipt  of any
      indemnification  payments hereunder. Any party seeking indemnity hereunder
      shall use Commercially Reasonable Efforts to seek coverage (including both
      costs of defense and indemnity) under applicable  insurance  policies with
      respect to any such Indemnifiable Loss.

      (e) The expiration or  termination of any covenant or agreement  shall not
affect  the  Parties'  obligations  under  this  Section  8.1 if the  Indemnitee
provided the Person  required to provide  indemnification  under this  Agreement
(the  "Indemnifying  Party") with proper  notice of the claim or event for which
indemnification   is   sought   prior  to  such   expiration,   termination   or
extinguishment.

      (f) Except to the extent otherwise  provided in Article IX, the rights and
remedies of Sellers,  GPU and Buyer under this Article VIII are exclusive and in
lieu of any and all other rights and remedies which  Sellers,  GPU and Buyer may
have under this Agreement or otherwise for monetary relief,  with respect to (i)
any breach of or failure to perform any covenant,  agreement,  or representation
or warranty set forth in this Agreement, after the occurrence of the Closing, or
(ii) the Assumed Liabilities or

                                      81






the Excluded Liabilities, as the case may be. The indemnification obligations of
the Parties set forth in this Article VIII apply only to matters  arising out of
this  Agreement,  excluding the Ancillary  Agreements.  Any  Indemnifiable  Loss
arising  under or pursuant to an  Ancillary  Agreement  shall be governed by the
indemnification  obligations, if any, contained in the Ancillary Agreement under
which the Indemnifiable Loss arises.

      (g)  Notwithstanding  anything to the contrary herein, no party (including
an Indemnitee)  shall be entitled to recover from any other party  (including an
Indemnifying Party) for any liabilities,  damages, obligations, payments losses,
costs,  or  expenses  under  this  Agreement  any amount in excess of the actual
compensatory  damages,  court costs and reasonable  attorney's and other advisor
fees suffered by such party.  Buyer,  Sellers and GPU waive any right to recover
punitive,  incidental,  special,  exemplary and consequential damages arising in
connection  with or with  respect  to this  Agreement.  The  provisions  of this
Section 8.1(g) shall not apply to indemnification for a Third Party Claim.

      8.2   Defense of Claims.

      (a) If any Indemnitee  receives notice of the assertion of any claim or of
the  commencement  of any claim,  action,  or proceeding  made or brought by any
Person who is not a party to this  Agreement or any Affiliate of a Party to this
Agreement (a "Third Party Claim") with respect to which indemnification is to be
sought from an Indemnifying  Party, the Indemnitee shall give such  Indemnifying
Party  reasonably  prompt written notice  thereof,  but in any event such notice
shall not be given  later than ten (10)  calendar  days  after the  Indemnitee's
receipt of notice of such Third Party  Claim.  Such notice  shall  describe  the
nature of the Third  Party Claim in  reasonable  detail and shall  indicate  the
estimated amount, if practicable, of the Indemnifiable Loss that has been or may
be sustained by the Indemnitee.  The  Indemnifying  Party will have the right to
participate  in or, by giving  written  notice  to the  Indemnitee,  to elect to
assume the defense of any Third Party Claim at such Indemnifying Party's expense
and by such Indemnifying Party's own counsel,  provided that the counsel for the
Indemnifying Party who shall conduct the defense of such Third Party Claim shall
be reasonably satisfactory to the Indemnitee.  The Indemnitee shall cooperate in
good faith in such defense at such Indemnitee's own expense.  If an Indemnifying
Party elects not to assume the defense of any Third Party Claim,  the Indemnitee
may  compromise  or settle  such Third  Party  Claim over the  objection  of the
Indemnifying Party, which settlement or compromise shall conclusively  establish
the Indemnifying Party's liability pursuant to this Agreement.

                                      82





      (b) (i) If, within ten (10)  calendar  days after an  Indemnitee  provides
written  notice  to the  Indemnifying  Party  of any  Third  Party  Claims,  the
Indemnitee  receives  written  notice  from the  Indemnifying  Party  that  such
Indemnifying  Party has  elected to assume the defense of such Third Party Claim
as provided in Section 8.2(a), the Indemnifying Party will not be liable for any
legal expenses  subsequently  incurred by the Indemnitee in connection  with the
defense thereof; provided, however, that if the Indemnifying Party shall fail to
take  reasonable  steps  necessary to defend  diligently  such Third Party Claim
within twenty (20) calendar days after receiving notice from the Indemnitee that
the Indemnitee  believes the  Indemnifying  Party has failed to take such steps,
the  Indemnitee may assume its own defense and the  Indemnifying  Party shall be
liable for all  reasonable  expenses  thereof.  (ii)  Without the prior  written
consent  of the  Indemnitee,  the  Indemnifying  Party  shall not enter into any
settlement  of any Third Party Claim which would lead to liability or create any
financial  or other  obligation  on the part of the  Indemnitee  for  which  the
Indemnitee is not entitled to indemnification hereunder. If a firm offer is made
to settle a Third Party Claim without  leading to liability or the creation of a
financial  or other  obligation  on the part of the  Indemnitee  for  which  the
Indemnitee is not entitled to  indemnification  hereunder  and the  Indemnifying
Party desires to accept and agree to such offer,  the  Indemnifying  Party shall
give written notice to the Indemnitee to that effect. If the Indemnitee fails to
consent to such firm offer  within ten (10)  calendar  days after its receipt of
such notice,  the  Indemnifying  Party shall be relieved of its  obligations  to
defend  such Third  Party  Claim and the  Indemnitee  may contest or defend such
Third Party Claim.  In such event,  the maximum  liability  of the  Indemnifying
Party as to such Third Party Claim will be the amount of such  settlement  offer
plus reasonable costs and expenses paid or incurred by Indemnitee up to the date
of said notice.

      (c) Any claim by an Indemnitee on account of an  Indemnifiable  Loss which
does not result from a Third Party Claim (a "Direct Claim") shall be asserted by
giving the Indemnifying Party reasonably prompt written notice thereof,  stating
the  nature of such claim in  reasonable  detail and  indicating  the  estimated
amount,  if  practicable,  but in any event such notice shall not be given later
than ten (10)  calendar days after the  Indemnitee  becomes aware of such Direct
Claim,  and the  Indemnifying  Party shall have a period of thirty (30) calendar
days within which to respond to such Direct  Claim.  If the  Indemnifying  Party
does not respond within such thirty (30) calendar day period,  the  Indemnifying
Party shall be deemed to have accepted  such claim.  If the  Indemnifying  Party
rejects such


                                      83





claim,  the  Indemnitee  will  be  free  to seek  enforcement  of its  right  to
indemnification under this Agreement.


      (d) If the amount of any Indemnifiable Loss, at any time subsequent to the
making of an  indemnity  payment in  respect  thereof,  is reduced by  recovery,
settlement or otherwise under or pursuant to any insurance coverage, or pursuant
to any claim,  recovery,  settlement  or payment  by,  from or against any other
entity,  the amount of such  reduction,  less any costs,  expenses  or  premiums
incurred in connection  therewith  (together with interest thereon from the date
of payment thereof at the publicly  announced prime rate then in effect of Chase
Manhattan  Bank) shall promptly be repaid by the Indemnitee to the  Indemnifying
Party.

      (e) A failure to give timely  notice as provided in this Section 8.2 shall
not affect the rights or obligations of any Party hereunder  except if, and only
to the extent that, as a result of such failure, the Party which was entitled to
receive such notice was actually prejudiced as a result of such failure.


                                   ARTICLE IX

                                   TERMINATION

      9.1 Termination. (a) This Agreement may be terminated at any time prior to
the Closing Date by mutual written consent of Sellers and Buyer.

            (b) This  Agreement may be terminated by Sellers or Buyer if (i) any
Federal or state  court of  competent  jurisdiction  shall have issued an order,
judgment or decree permanently  restraining,  enjoining or otherwise prohibiting
the  Closing,  and such order,  judgment or decree  shall have become  final and
nonappeallable  or (ii) any statute,  rule,  order or regulation shall have been
enacted or issued by any Governmental  Authority which,  directly or indirectly,
prohibits the  consummation  of the Closing;  or (iii) the Closing  contemplated
hereby  shall have not occurred on or before the day which is 12 months from the
date of this  Agreement  (the  "Termination  Date");  provided that the right to
terminate this Agreement  under this Section 9.1(b) (iii) 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 to occur on or
before such date; and provided,  further,  that if on the day which is 12 months
from the date of this  Agreement  the  conditions  to the  Closing  set forth in
Section 7.1(b) or (c) or 7.2(b), (c) or (d)
                                      84





shall not have been  fulfilled but all other  conditions to the Closing shall be
fulfilled  or shall be capable of being  fulfilled,  then the  Termination  Date
shall be the day which is 18 months from the date of this Agreement.

            (c) Except as otherwise  provided in this Agreement,  this Agreement
may be terminated by Buyer if any of Buyer Required  Regulatory  Approvals,  the
receipt of which is a condition to the  obligation  of Buyer to  consummate  the
Closing as set forth in Section  7.1(c),  shall have been denied (and a petition
for rehearing or refiling of an application  initially denied without  prejudice
shall also have been denied) or shall have been  granted but  contains  terms or
conditions which do not satisfy the closing condition in Section 7.1(c).

            (d) This Agreement may be terminated by Sellers,  if any of Sellers'
Required  Regulatory  Approvals,  the  receipt  of which is a  condition  to the
obligation of Sellers or GPU to  consummate  the Closing as set forth in Section
7.2(c),  shall have been denied (and a petition for  rehearing or refiling of an
application  initially denied without  prejudice shall also have been denied) or
shall have been granted but contains  terms or  conditions  which do not satisfy
the closing condition in Section 7.2(c).

            (e) This  Agreement  may be  terminated by Buyer if there has been a
violation  or  breach  by  Sellers  or GPU of any  covenant,  representation  or
warranty  contained in this Agreement  which has resulted in a Material  Adverse
Effect and such  violation  or breach is not cured by the earlier of the Closing
Date or the date thirty  (30) days after  receipt by Sellers or GPU, as the case
may be, of notice  specifying  particularly  such violation or breach,  and such
violation or breach has not been waived by Buyer.

            (f) This Agreement may be terminated by Sellers, if there has been a
material  violation  or  breach  by Buyer  of any  covenant,  representation  or
warranty  contained in this  Agreement and such violation or breach is not cured
by the earlier of the Closing Date or the date thirty (30) days after receipt by
Buyer of notice  specifying  particularly  such  violation  or breach,  and such
violation or breach has not been waived by Sellers.

            (g) This  Agreement may be terminated by Sellers if there shall have
occurred any change that is materially  adverse to the  business,  operations or
conditions (financial or otherwise) of Buyer.


                                      85





            (h) This  Agreement  may be terminated by either of Sellers or Buyer
in accordance with the provisions of Section 6.11(b).

      9.2  Procedure  and  Effect  of  No-Default  Termination.  In the event of
termination  of this  Agreement  by either or both of the  Parties  pursuant  to
Section 9, written  notice thereof shall  forthwith be given by the  terminating
Party to the other Party, whereupon, if this Agreement is terminated pursuant to
any of Sections  9.1(a)  through (d) and 9.1(g) and (h), the  liabilities of the
Parties hereunder will terminate, except as otherwise expressly provided in this
Agreement,  and  thereafter  neither  Party shall have any recourse  against the
other by reason of this Agreement.


                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

may be amended,  modified or supplemented  only by written agreement of Sellers,
Buyer and GPU.

      10.2 Waiver of Compliance;  Consents. Except as otherwise provided in this
Agreement,  any  failure of any of the  Parties to comply  with any  obligation,
covenant,  agreement or condition  herein may be waived by the Party entitled to
the benefits thereof only by a written  instrument  signed by the Party granting
such  waiver,  but  such  waiver  of such  obligation,  covenant,  agreement  or
condition  shall not  operate as a waiver of, or estoppel  with  respect to, any
subsequent failure to comply therewith.

      10.3 No  Survival.  Each and every  representation,  warranty and covenant
contained  in this  Agreement  (other than the  covenants  contained in Sections

                                      86





survive  the Closing  Date;  and none of  Sellers,  Buyer , GPU or any  officer,

employment,  and no provision of this  Agreement  shall create any rights in any
such  Persons in respect  of any  benefits  that may be  provided,  directly  or
indirectly,  under any employee benefit plan or arrangement  except as expressly
provided  for  thereunder.  Notwithstanding  the  foregoing,  without  the prior
written  consent  of  Sellers,  (i)  Buyer  may  assign  all of its  rights  and
obligations  hereunder to any majority owned Subsidiary (direct or indirect) and
upon Sellers' receipt of notice from Buyer of any such assignment, such assignee
will be deemed to have assumed,  ratified, agreed to be bound by and perform all
such  obligations,  and all  references  herein to "Buyer"  shall  thereafter be
deemed to be references to such assignee, in each case without the necessity for
further act or evidence by the Parties hereto or such  assignee,  and (ii) Buyer
or its permitted assignee may assign,  transfer,  pledge or otherwise dispose of
(absolutely  or as security)  its rights and  interests  hereunder to a trustee,
lending  institutions  or other party for the purposes of leasing,  financing or
refinancing  the Purchased  Assets,  including such an  assignment,  transfer or
other  disposition  upon or pursuant to the exercise of remedies with respect to
such leasing,  financing or refinancing,  or by way of  assignments,  transfers,
pledges,  or other dispositions in lieu thereof (and any such assignee may fully
exercise its rights  hereunder or under any other agreement and pursuant to such
assignment  without any further  prior consent of any party  hereto);  provided,
however,  that  no such  assignment  in  clause  (i) or (ii)  shall  relieve  or
discharge the assignor from any of its obligations hereunder. The Sellers agree,
at Buyer's  expense,  to execute and deliver such documents as may be reasonably
necessary  to  accomplish  any  such  assignment,   transfer,  pledge  or  other
disposition of rights and interests  hereunder so long as Sellers'  rights under
this  Agreement  are not  thereby  altered,  amended,  diminished  or  otherwise
impaired.

      10.6  Governing Law.  This Agreement shall be governed by and construed
in accordance with the law of the State of New York (without giving effect to
conflict of law principles) as to all

RIGHT TO A JURY TRIAL WITH  RESPECT  TO ANY ACTION OR CLAIM  ARISING  OUT OF ANY
DISPUTE IN  CONNECTION  WITH THIS  AGREEMENT  OR THE  TRANSACTIONS  CONTEMPLATED

      10.7  Counterparts.  This  Agreement  may  be  executed  in  two  or  more

      10.11 Bulk Sales Laws. Buyer acknowledges that,  notwithstanding  anything
in this  Agreement to the  contrary,  Sellers may, in its sole  discretion,  not
comply  with  the  provision  of the  bulk  sales  laws of any  jurisdiction  in
connection with the  transactions  contemplated by this Agreement.  Buyer hereby
waives  compliance by Sellers with the  provisions of the bulk sales laws of all
applicable jurisdictions.

      10.12 U.S. Dollars.  Unless otherwise stated, all dollar amounts set

      10.13 Zoning Classification. Without limitation of Sections 7.1(o) and 7.3
Buyer  acknowledges  that the Real Properties are zoned as set forth in Schedule
10.13.

      10.14  Sewage  Facilities.  Except as set forth in Schedule  10.14,  Buyer

serve the Real Property.  Accordingly, any additional sewage disposal planned by
Buyer will  require an  individual  (on-site)  sewage  system and all  necessary
permits as required by the Pennsylvania  Sewage  Facilities Act (the "Facilities
Act").  Buyer recognizes that certain of the existing  individual sewage systems
on the Real Property may have been  installed  pursuant to  exemptions  from the
requirements  of the  Facilities Act or prior to the enactment of the Facilities
Act and that soils and site testing may not have been  performed  in  connection
therewith.  The owner of the property or properties  served by such a system, at
the  time  of any  malfunction,  may  be  held  liable  for  any  contamination,
pollution,  public health hazard or nuisance  which occurs as the result of such
malfunction.

      10.15 GPU.  Buyer  acknowledges  and agrees that the  liability of GPU and
each Seller hereunder is several as to each of their respective  obligations and
not joint.
