imposed by any federal, state or local government on the ownership, lease,
maintenance, use or sale of the Purchased Assets on or after the Closing Date,
except for any Income Taxes attributable to income received by Seller; and

            (e) For purposes of clarification, Buyer acknowledges that it
shall assume and be fully responsible for holding in its accounts sufficient
SO2 Allowances and NOx Allowances to cover emissions of SO2 and NOx from all
of the Sites for all of the calendar year in which the Closing occurs,
including the period of such year prior to the Closing Date.

      2.4 Excluded Liabilities. Notwithstanding Section 2.3, Buyer shall not
assume or be obligated to pay, perform or otherwise discharge the following
Liabilities of Seller (the "Excluded Liabilities"):

Closing Date.

            (h) Any Liability under or related to Environmental Laws or the
common law arising as a result of or in connection with loss of life, injury

Substances disposed of or Released at the Purchased Assets have migrated; and

            (j) Any Liability under or related to Environmental Laws or the

maintenance or operation by Seller or its Affiliates of the Transmission
Assets prior to, on or after the Closing Date, except to the extent caused by
the acts or omissions of Buyer or Buyer's ownership, lease, maintenance or
operation of the Purchased Assets.

      2.5 Control of Litigation. The Parties agree and acknowledge that Seller
shall be entitled exclusively to control, defend and settle any suit, action
or proceeding, and any investigation arising out of or relating to any

                                  ARTICLE III

                                  THE CLOSING

      3.1 Closing. The sale, assignment, conveyance, transfer and delivery of
the Purchased Assets by Seller to Buyer, and the purchase, assumption and
acquisition by Buyer of the Purchased Assets and the Assumed Liabilities, and
the consummation of the other transactions contemplated hereby, shall take
place at a closing (the "Closing") to be held at the offices of Skadden, Arps,
Slate, Meagher & Flom LLP, One Rodney Square, Wilmington, Delaware, at 10:00
a.m. local time on the first Business Day after August 31, 2000 that is ten
(10) Business Days after the date on which the last of the conditions
precedent to the Closing set forth in Sections 7.1(a) and (c), and Sections
7.2(a) and (c) of this Agreement shall have been satisfied or, to the extent
permitted by applicable Law, waived by the Party for whose benefit such
conditions precedent exist, or at such other date, time and location
thereafter as may be agreed

                                       20
<PAGE>

upon in writing between Buyer and Seller. The date on which the Closing actually
occurs is hereinafter called the "Closing Date." The Closing shall be effective
for all purposes as of 12:01 a.m., New York City time, on the Closing Date.

      3.2 Payment of Purchase Price.

            (a) Upon the terms and subject to the conditions set forth in this
Agreement, in consideration of the aforesaid sale, assignment, conveyance,
transfer and delivery of the Purchased Assets, Buyer shall, at the Closing,
(i) pay to Seller cash in the aggregate amount of $96,136,000 plus the amount,
if any, by which the Closing Adjustment Amount exceeds the Target Adjustment
Amount, or minus the amount, if any, by which the Target Adjustment Amount
exceeds the Closing Adjustment Amount (the "Purchase Price"), and (ii) assume
and agree to pay, perform and otherwise discharge the Assumed Liabilities.

            (b) At least five (5) Business Days prior to the Closing Date,
Seller shall provide to Buyer its good faith estimate of the Closing
Adjustment Amount, which estimate shall be certified in writing by an
appropriate officer of Seller (the "Estimated Adjustment Amount").

            (c) At the Closing, in furtherance but not in duplication of
Section 3.2(a) and without limiting the generality of Section 3.7, Buyer shall
pay to Seller cash in an aggregate amount equal to $96,136,000 plus the
amount, if any, by which the Estimated Adjustment Amount exceeds the Target
Adjustment Amount, or minus the amount, if any, by which the Target Adjustment
Amount exceeds the Estimated Adjustment Amount (the "Closing Payment"). The
Closing Payment shall be paid to Seller by Buyer at the Closing by wire
transfer of immediately available funds to the account of Seller designated by
Seller at least two (2) Business Days prior to the Closing Date.

      3.3 Adjustment to Purchase Price.

            (a) Within sixty (60) days after the Closing Date, Seller shall
deliver to Buyer, at Seller's sole cost and expense, a statement setting forth
the Closing Adjustment Amount (the "Closing Statement"). Contemporaneously,
Seller shall deliver to Buyer a schedule setting forth a calculation of the
Purchase Price and the amount of any payment to be made, and by whom, pursuant
to Section 3.3(c).

            (b) In the event that Buyer is in disagreement with the Closing
Statement, and in the event that the aggregate amount of such disagreements
exceeds $100,000, Buyer shall, within ten (10) Business Days after receipt of
the Closing Statement, notify Seller of such disagreements setting forth with
specificity the nature and amounts thereof. In the event that Buyer is in
disagreement with only a portion of the Closing Statement, Buyer or Seller, as
the case may be, shall pay all undisputed amounts in the manner set forth in
Section 3.3(c); and all other amounts shall be paid at such time as all
disagreements are resolved in accordance with this Section 3.3(b).

                                       21
<PAGE>

If (i) the aggregate amount of the disagreements referred to in this Section
3.3(b) does not exceed $100,000 or (ii) Buyer fails to notify Seller of all
disagreements within the ten (10) Business Day period provided for herein, then
the Closing Statement, as delivered by Seller pursuant to Section 3.3(a), shall
be final, binding and conclusive on the Parties hereto. If Buyer is in
disagreement with the Closing Statement and notifies Seller within such ten (10)
Business Day period, then the Parties shall promptly attempt to resolve such
disagreements by negotiation. If the Parties are unable to resolve such
disagreements within thirty (30) days following such notice of disagreement by
Buyer, the Parties shall appoint an Independent Accounting Firm within forty-
five (45) days following such notice, which shall review the Closing Statement
and determine the Closing Adjustment Amount. Resolution of any disagreements
shall be made by the Independent Accounting Firm in a writing addressed to all
Parties within thirty (30) days following referral to it by the Parties of such
disagreements in accordance with this Agreement. The findings of such
Independent Accounting Firm shall be final, binding and conclusive on the
Parties. All costs and fees of the Independent Accounting Firm shall be borne
equally by Buyer and Seller.

            (c) No later than the fifth (5th) Business Day following the
determination of the Closing Adjustment Amount pursuant to Section 3.3(b),
either (i) Seller shall pay Buyer the amount, if any, by which the Closing
Payment exceeds the Purchase Price, or (ii) Buyer shall pay Seller the amount,
if any, by which the Purchase Price exceeds the Closing Payment, in either
case, together with simple interest accruing on such payment at the Prime Rate
from the Closing Date through and including the date of payment, by wire
transfer of immediately available funds to an account designated by the
receiving Party. As used herein, "Prime Rate" means, as of any date, the prime
rate as published in The Wall Street Journal on such date or, if not published
on such date, on the most recent date of publication.

      3.4 Tax Reporting and Allocation of Purchase Price. Buyer and Seller
shall use their respective reasonable best efforts to agree in good faith upon
an allocation among the Purchased Assets of the sum of the Purchase Price and
the Assumed Liabilities consistent with Section 1060 of the Code and the
Treasury Regulations thereunder within sixty (60) days after the Closing Date.
In the event that the Parties cannot agree on a mutually satisfactory
allocation within such sixty-day period, the Parties shall appoint an
Independent Accounting Firm that shall, at Seller's and Buyer's joint expense,
determine the appropriate allocation. The finding of such Independent
Accounting Firm shall be final, binding and conclusive on the Parties. After
determination of the allocation by agreement of the Parties or by binding
determination of the Independent Accounting Firm, Buyer and Seller shall file,
for the tax year in which the Closing occurs, Internal Revenue Service Form
8594, and all Tax Returns, in accordance with such allocation. Buyer and
Seller shall report the transactions contemplated by this Agreement for United
States federal Income Tax and all other Tax purposes in a manner consistent
with the allocation determined pursuant to this Section 3.4. Buyer and Seller
shall provide the other promptly with any information required to complete
Form 8594. Buyer and Seller 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 Purchase Price and the Assumed Liabilities.

                                       22

      3.5 Prorations.

            (a) Buyer and Seller agree that, except as otherwise provided in
this Agreement, all of the items customarily prorated relating to the
ownership, lease, maintenance or operation of the Purchased Assets, including
those listed below (but not including Income Taxes), shall be prorated as of
the Closing Date, with Seller liable to the extent such items relate to any
period prior to the Closing Date, and Buyer liable to the extent such items
relate to any period on or after the Closing Date (measured in the same units
used to compute the item in question, otherwise measured by calendar days):

                  (i) Personal property, real estate and occupancy Taxes
(other than any Pennsylvania public utility realty tax pursuant to 72 P.S. ss.
8102-A ("PURTA"), as well as additional assessments and surtaxes relating to
PURTA (collectively, the "PURTA Assessment") which are addressed in Section
3.5(c)), assessments and other charges, if any, on or with respect to the
ownership, lease, maintenance or operation of the Purchased Assets;

                  (ii) Rent, Taxes and all other items (including prepaid
services and goods not included in Inventory), in each case, payable by or to
Seller under any of the Seller's Agreements;

                  (iii) Any permit, license, registration, compliance
assurance fees or other fees with respect to any Transferable Permit;

                  (iv) Sewer rents and charges for water, telephone,
electricity and other utilities;

                  (v) Insurance premiums paid on or with respect to the
ownership, lease, maintenance or operation of the Purchased Assets to the
extent payable under any policy or other arrangement included among the
Seller's Agreements; and

                  (vi) Prepaid operating and maintenance expenses, whether
arising under the Jointly Owned Stations Operating Agreements or otherwise.

            (b) Seller or Buyer, as the case may be, shall promptly reimburse
the other Party that portion of any amount paid by such other Party to the
extent relating to the period for which Seller or Buyer, as the case may be,
is liable under Section 3.5(a), in each case, upon presentation of a statement
setting forth in reasonable detail the nature and amount of any such payment.
In connection with the prorations set forth in Section 3.5(a), if actual
figures are not available on the Closing Date, the proration shall be
calculated based upon the respective amounts accrued through the Closing Date
or paid for the most recent year or other appropriate period for which such
amounts paid are available. All prorated amounts shall be recalculated and
paid to the appropriate Party within sixty (60) days after the date that the
previously unavailable actual figures become available. Seller and Buyer shall
furnish each other with such documents

                                       23
<PAGE>

and other records as may be reasonably requested in order to confirm all
proration calculations made pursuant to this Section 3.5. Notwithstanding
anything to the contrary herein, no proration shall be made under this Section
3.5 with respect to (i) real property Tax refunds that are Excluded Assets under
Section 2.2(h) or (ii) Taxes payable by Buyer pursuant to Section 6.5(a).

            (c) (i) Seller shall be responsible for and pay the PURTA
Assessment imposed on any public utilities which are included in the Purchased
Assets located in the Commonwealth of Pennsylvania (the "Pennsylvania Assets")
with respect to the calendar year in which the Closing occurs. Buyer shall
reimburse Seller in accordance with this Section 3.5(c) for its proportionate
share of the PURTA Assessment for the calendar year in which the Closing
occurs. Buyer's proportionate share shall be based upon the number of days
within the Closing year that Buyer owned the Pennsylvania Assets. For example,
if the Closing were to occur on December 1, 2000, and $1,000,000 of PURTA
Assessment for calendar year 2000 had been paid, then Buyer's proportionate
share of such PURTA Assessment would be equal to the product obtained by
multiplying $1,000,000 by a fraction, the numerator of which would be the
number of days in calendar year 2000 during which Buyer owned the Pennsylvania
Assets (31), and the denominator of which would be the number of days in
calendar year 2000 (366). Therefore, the aggregate amount of Buyer's
proportionate share of the PURTA Assessment would be $1,000,000 multiplied by
31/366, or $84,699.50. Seller shall compute Buyer's obligation hereunder and
notify Buyer of such obligation at least five (5) Business Days before the
Closing. The reimbursement payable by Buyer to Seller hereunder shall be paid
at Closing.

                  (ii) In the event Seller or Buyer obtains a refund of the
PURTA Assessment paid with respect to the year in which the Closing occurred,
any such refund, net of any costs incurred by the Party obtaining such refund
(a "Net PURTA Refund"), shall be prorated in accordance with this Section
3.5(c). Any prorated Net PURTA Refund shall be paid to the Party entitled to
such prorated Net PURTA Refund promptly upon final adjudication or settlement
of such Net PURTA Refund. Buyer and Seller shall provide each other with such
cooperation and information as either of them reasonably may request of the
other in connection with the filing of any refund claim for a PURTA
Assessment, or the conduct of any audit, dispute, proceeding, suit or action
concerning any PURTA Assessment.

      3.6 Deliveries by Seller. At the Closing, Seller shall deliver, or cause
to be delivered, the following to Buyer:

            (a) One or more Limited Warranty Deeds, duly executed by Seller
and in recordable form;

            (b) The Bills of Sale, duly executed by Seller;

            (h) All such other agreements, documents, instruments and writings
as shall, in the reasonable opinion of Buyer and its counsel, be necessary to
sell, assign, convey, transfer and deliver to Buyer the Purchased Assets, in
accordance with this Agreement and, where necessary or desirable, in
recordable form, provided that Seller shall not be required to prepare or
obtain any survey, abstract, title opinion or title insurance policy with
respect to the Real Property; and

            (i) Such other agreements, documents, instruments and writings as
are required to be delivered by Seller at or prior to the Closing Date
pursuant to this Agreement or otherwise reasonably required in connection
herewith.

      3.7 Deliveries by Buyer. At the Closing, Buyer shall deliver, or cause
to be delivered, the following to Seller:

necessary for Buyer to purchase and acquire the Purchased Assets, and to
assume the Assumed Liabilities, in each case, in accordance with this
Agreement and, where necessary or desirable, in recordable form; and

            (g) Such other permits, agreements, documents, instruments and
writings as are required to be delivered by Buyer at or prior to the Closing

      3.8 Post-Closing Excluded Asset Deliveries. In the event that Seller or
Buyer, or any of their respective Representatives, shall determine after the
Closing that any Excluded Asset is in the possession of Buyer or any of its
Representatives, Buyer shall, or shall cause any such Representative to,
promptly, but in no event later than five (5) Business Days following such
determination, pay or deliver, or cause to be paid or delivered, to Seller

      3.9 Relationship of this Agreement and Related Purchase Agreements. The
transactions contemplated by this Agreement, together with the transactions
contemplated by the Related Purchase Agreements, are intended by the Parties
to be consummated substantially simultaneously; and if any of the transactions
contemplated hereby or by any of the Related Purchase Agreements are not
consummated simultaneously on the Closing Date in accordance with the terms
and subject to the conditions set forth herein and therein, as applicable,
then each Party shall take, or cause to be taken, all actions, and do, or
cause to be done, all things, in each case, that are necessary to dissolve and
invalidate all transactions contemplated hereby; provided, however, that if
the failure to consummate the transactions contemplated hereby or by the
Related Purchase Agreements results from a default or breach of a party under
this Agreement or any of the Related Purchase Agreements, then nothing in the
foregoing shall preclude or limit the rights or remedies of any Party in
connection with such default or breach. Notwithstanding any provision
contained herein to the contrary, if all conditions to the obligations of all
parties to this Agreement and the ACE Related Purchase Agreement to consummate
the transactions contemplated hereby and thereby have been satisfied or, to
the extent permitted by applicable Law, waived, but, for any reason, the
transactions contemplated by the DP&L Related Purchase Agreements cannot be
consummated simultaneously therewith, then the Parties shall, at Buyer's
option and in its sole discretion, consummate the transactions contemplated by
this Agreement and the ACE Related Purchase Agreement; provided, however, that
nothing contained in this

                                       26
<PAGE>

Section 3.9 shall be construed as relieving Buyer of any of its obligations
under the DP&L Related Purchase Agreements, as set forth therein.


                                  ARTICLE IV

                   REPRESENTATIONS AND WARRANTIES OF SELLER

      Seller hereby represents and warrants to Buyer as follows (all such
representations and warranties, except those set forth in Sections 4.1 and
4.2, being made to the Knowledge of Seller):

      4.1 Organization; Qualification. Seller is a corporation duly
incorporated, validly existing and in good standing under the laws of the
State of New Jersey and has all requisite corporate power and authority to
own, lease and operate its properties and to carry on its business as it is
now being conducted. 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 requires it to be so qualified,
except to the extent that the failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect.

      4.2 Authority. Seller has full corporate power and authority to execute
and deliver this Agreement and each Additional Agreement to which it is a
party and to consummate the transactions contemplated hereby and thereby. The
execution and delivery by Seller of this Agreement and each Additional
Agreement to which it is a party and the consummation by Seller of the
transactions contemplated hereby and thereby have been duly and validly
authorized by all necessary corporate action required on the part of Seller.
This Agreement has been duly and validly executed and delivered by Seller and,
subject to the receipt of Seller's Required Regulatory Approvals, this
Agreement constitutes, and upon the execution and delivery by Seller of each
Additional Agreement to which it is a party, each such Additional Agreement
will constitute, the legal, valid and binding obligation of Seller,
enforceable against Seller in accordance with its terms, except that such
enforceability may be limited by applicable bankruptcy, insolvency,
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).

      4.3 Consents and Approvals; No Violation.

            (a) Except as set forth on Schedule 4.3(a), subject to obtaining
or making all Seller's Required Regulatory Approvals, neither the execution
and delivery by Seller of this Agreement and the Additional Agreements to
which it is a party nor the consummation by Seller of the transactions
contemplated hereby or thereby will (i) conflict with or result in any breach
of any provision of the certificate or articles of incorporation or bylaws of
Seller; (ii) result in a default (or give rise to any right of termination,
cancellation or acceleration) under any of the

                                       27
<PAGE>

terms, conditions or provisions of any note, bond, mortgage, indenture, material
agreement or other instrument or obligation to which 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
consents, approvals or waivers have been, or will be prior to the Closing
obtained, or which would not, individually or in the aggregate, have a Material
Adverse Effect; or (iii) constitute violations of any Law, order, judgment or
decree applicable to Seller, which violations, individually or in the aggregate,
would have a Material Adverse Effect.

            (b) Except for consents, approvals, filings and notices (i)
required under the HSR Act or (ii) set forth on Schedule 4.3(b) (the consents,
approvals, filings and notices referred to in clause (ii) of this sentence are
collectively referred to herein as the "Seller's Required Regulatory
Approvals"), no consent or approval of, filing with, or notice to, any
Governmental Authority is necessary for the execution and delivery by Seller
of this Agreement and the Additional Agreements to which it is a party or the
consummation by Seller of the transactions contemplated hereby or thereby,
other than (i) such consents, approvals, filings and notices which, if not
obtained or made, would not materially impair Seller's ability to perform its
material obligations under this Agreement or such Additional Agreements; (ii)
such consents, approvals, filings and notices which become applicable to
Seller or the Purchased Assets as a result of the 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; and (iii) such consents, approvals, filings and
notices, the failure of which to obtain or make would not, individually or in
the aggregate, have a Material Adverse Effect.

      4.4 Insurance. Except as set forth on Schedule 4.4, all material

is considered in a proceeding at law or in equity).

      5.3 Consents and Approvals; No Violation.

            (a) Except as set forth on Schedule 5.3(a), and subject to
obtaining or making all Buyer's Required Regulatory Approvals, neither the

Buyer, any such Subsidiary or any of their respective properties and assets
may be bound, except for such defaults (or rights of termination, cancellation

the financial position, results of operations and cash flow of Buyer at and
for the periods therein.

Effect or would materially impair such Buyer's ability to consummate the

                                  ARTICLE VI

                           COVENANTS OF THE PARTIES

      6.1 Access to Information.

            (a) Between the date of this Agreement and the Closing Date,
Seller shall: (i) use its Commercially Reasonable Efforts to give Buyer and
its Representatives, during ordinary business hours and upon reasonable
notice, reasonable access to all books, records, plans, offices and other
facilities and properties included in the Purchased Assets; (ii) furnish Buyer
with such financial and operating data and other information in the possession
of Seller with respect to the Purchased Assets as Buyer may from time to time
reasonably request; and (iii) furnish Buyer with all such other information in
the possession of Seller as shall be reasonably necessary to enable Buyer to
verify the accuracy of the representations and warranties of Seller contained
in this Agreement; provided, however, that (A) any such inspections and
investigations shall be conducted in such manner as not to interfere
unreasonably with the operation of the Purchased Assets, (B) Seller shall not
be required to take any action which would constitute a waiver of the
attorney-client or other privilege, (C) Seller need not supply Buyer with any
information which Seller is under a legal or contractual obligation not to
supply and (D) Seller shall not be required to supply Buyer with any
information with respect to the Jointly Owned Stations to which Seller is not
entitled pursuant to the terms of the Jointly Owned Stations Operating
Agreements. Notwithstanding anything herein to the contrary, prior to the
Closing Date, Buyer shall not have the right to perform or conduct, or cause
to be performed or conducted, any environmental sampling or testing at, in, on
or underneath any Jointly Owned Station.

            (b) All information furnished to or obtained by Buyer and Buyer's
Representatives pursuant to this Section 6.1 shall be Proprietary Information
and shall be kept confidential in accordance with the terms of the
Confidentiality Agreement. Nothing in this Section 6.1 is intended to or shall
be deemed to amend, supplement or otherwise modify the obligations of Buyer,
its Representatives or its Affiliates under the Confidentiality Agreement, all
of which remain in effect until termination of such agreement in accordance
with its terms.

            (c) For a period of seven (7) years from and after the Closing
Date, each Party and its Representatives shall have reasonable access to all
of the books and records of the Purchased Assets in the possession of the
other Party to the extent that such access may

                                       33
<PAGE>

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 or the Excluded Assets. Such access shall be
afforded by the Party in possession of any such books and records upon receipt
of reasonable advance 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 6.1(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, such Party shall, prior to such disposition, give the
other Party a reasonable opportunity, at such other Party's cost and expense, to
segregate and remove such books and records as such other Party may select.

            (d) Buyer shall not, prior to the Closing Date, contact any
customer, vendor, supplier or employee of, or any other Person having business
dealings with, Seller or its Affiliates with respect to any aspect of the
Purchased Assets or the transactions contemplated hereby or by any Additional
Agreement, without the prior written consent of Seller, which consent shall
not be unreasonably withheld or delayed.

      6.2 Public Statements. Except as required by applicable Law or by
applicable rules of any national securities exchange, in which event the
Parties shall consult with each other in advance, prior to the Closing Date,
no press release or other public announcement, statement or comment in
response to any inquiry relating to the transactions contemplated by this
Agreement shall be issued, made or permitted to be issued or made by any Party
or its Representatives without the prior written consent of the other Party.

      6.3 Further Assurances.

            (a) Subject to the terms and conditions of this Agreement, each of
the Parties hereto shall use its reasonable 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 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 using its reasonable best
efforts to ensure satisfaction of the conditions precedent to each Party's
obligations hereunder, including obtaining all necessary consents, approvals
and authorizations of, and making all required notices or filings with, third
parties required to be obtained or made in order to consummate the
transactions hereunder, including the transfer of the Transferable Permits to
Buyer. Seller shall cooperate with Buyer in its efforts to obtain all other
Permits and Environmental Permits necessary for Buyer to operate the Purchased
Assets. Buyer shall perform all conditions required of Buyer in connection
with obtaining the Seller's Required Regulatory Approvals. No Party 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.

            (b) Without limiting the generality of Section 6.3(a):

                                       34
<PAGE>

                  (i) In the event that any Purchased Asset shall not have
been conveyed to Buyer at the Closing, Seller shall, subject to Section
6.3(b)(ii), use Commercially Reasonable Efforts after the Closing to convey
such asset to Buyer as promptly as practicable.

                  (ii) To the extent that Seller's rights under any material
Seller's Agreement may not be assigned without the consent, approval or
authorization of any third party which consent, approval or authorization has
not been obtained by the Closing Date, this Agreement shall not constitute an
agreement to assign such right if an attempted assignment would constitute a
breach of such Seller's Agreement or violate any applicable Law. If any
consent, approval or authorization to the assignment of any material Seller's
Agreement shall not be obtained, or if any attempted assignment would be
ineffective or would impair Buyer's rights and obligations under such Seller's
Agreement, such that Buyer would not acquire and assume the benefit and
detriment of all such rights and obligations, Seller, at its option and to the
fullest extent permitted by applicable Law and such Seller's Agreement, shall,
after the Closing Date, appoint Buyer to be Seller's agent with respect to
such Seller's Agreement, or, to the fullest extent permitted by applicable Law
and such Seller's Agreement, 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 under such Seller's
Agreement.

      6.4 Consents and Approvals. Without limiting the generality of Section
6.3(a):

            (a) As promptly as practicable after the date of this Agreement,
Seller and Buyer shall each file or cause to be filed with the Federal Trade
Commission and the United States Department of Justice all notifications
required to be filed under the HSR Act and the rules and regulations
promulgated thereunder, as amended from time to time, with respect to the
transactions contemplated hereby and by the Additional Agreements. The Parties
shall use their respective Commercially Reasonable Efforts to respond promptly
to any requests for additional information made by such agencies, and to cause
the applicable waiting period under the HSR Act to terminate or expire at the
earliest possible date after the date of filing. Buyer shall pay all filing
fees payable under the HSR Act but each Party shall bear its own costs and
expenses of the preparation of any filing.

            (b) As promptly as practicable after the date of this Agreement,
Seller and Buyer shall take, or cause to be taken, all actions, and do, or
cause to be done, all things necessary, proper or advisable under applicable
Laws to obtain all required consents and approvals of the NJBPU, the PaPUC,
the SEC and all other Governmental Authorities, and make all other filings and
give all other notices required to be made prior to the Closing with respect
to the transactions contemplated hereby and by the Additional Agreements. The
Parties shall respond promptly to any requests for additional information made
by such Persons, and use their respective Commercially Reasonable Efforts to
cause all such consents and approvals to be obtained or waived at the earliest
possible date after the date of filing. Each Party will bear its own costs of
the preparation of any such filing or notice; provided, however, that Buyer
shall

                                       35
<PAGE>

bear all costs associated with experts and consultants reasonably necessary for
the preparation of any such filing or notice or reasonably necessary to obtain
such consents and approvals as promptly as practicable.

            (c) Seller 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 Seller pursuant to state or
local Tax Law.

            (d) Without limiting the generality of Section 6.4(b), as promptly
as practicable after the date hereof, Buyer shall make all filings required by
the Federal Power Act. Prior to filing any application with the FERC, Buyer
shall submit such application to Seller for review and comment and shall
incorporate into such application all revisions reasonably requested. Buyer
shall be solely responsible for the cost of preparing and filing such
application, as well as all petition(s) for rehearing and all reapplications.
If any filing is rejected by the FERC, Buyer shall petition the FERC for
rehearing or permission to re-submit an application with the FERC, provided
that, in either case, such action has been approved by Seller.

      6.5 Certain Tax Matters.

            (a) All transfer, sales and similar Taxes ("Transfer Taxes")
incurred in connection with this Agreement and the Additional Agreements, and
the transactions contemplated hereby and thereby (including (i) sales Tax on
the sale or purchase of the Purchased Assets imposed by Pennsylvania and (ii)
transfer Tax on conveyances of interests in real property imposed by
Pennsylvania) shall be borne by Buyer (and, to the extent paid by Seller,
Buyer shall reimburse Seller upon request); provided, however, that if,
pursuant to Section 6.6(e), the transactions contemplated by this Agreement
are effectuated as a Like-Kind Exchange, then Seller shall bear such Transfer
Taxes to the extent that they exceed the amount of Transfer Taxes that would
have otherwise been incurred had the transactions not been effectuated as a
Like-Kind Exchange (and all such amounts shall be computed on an after-Tax
basis). Buyer, at its expense, shall prepare and file, to the extent required
by, or permissible under, applicable Law, all necessary Tax Returns and other
documentation with respect to all such Transfer Taxes, and, if required by
applicable Law, Seller shall join in the execution of all such Tax Returns and
other documentation; provided, however, that prior to the Closing Date, to the
extent applicable, Buyer shall provide to Seller appropriate certificates of
Tax exemption from each applicable Governmental Authority.

            (b) With respect to Taxes to be prorated in accordance with
Section 3.5, 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 such Tax Returns shall be subject to Seller's
approval, which approval shall not be unreasonably withheld or delayed. Buyer
shall make each

                                       36
<PAGE>

such Tax Return available for Seller's review and approval (which approval shall
not be unreasonably withheld or delayed) no later than fifteen (15) Business
Days prior to the due date for filing such Tax Return, it being understood that
Seller's failure to approve any such Tax Return shall not limit Buyer's
obligation to timely file such Tax Return and duly and timely pay all Taxes
shown to be due thereon.

            (c) Buyer and Seller 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, audit or other examination, or any proceeding,
by or before any Governmental Authority relating to Liability for Taxes, and
each Party shall retain and provide the requesting Party with all books and
records or other information which may be relevant to such Tax Return, audit,
examination or proceeding. All books, records and information obtained
pursuant to this Section 6.5(c) or pursuant to any other Section that provides
for the sharing of books, records and information or review of any Tax Return
or other instrument relating to Taxes shall be kept confidential by the
parties hereto in accordance with the terms and conditions set forth in the
Confidentiality Agreement.

            (d) In the event that a dispute arises between Seller and Buyer
regarding Taxes or any amount due under this Section 6.5, the affected Parties
shall attempt in good faith to resolve such dispute and any agreed-upon amount
shall be promptly paid to the appropriate Party. If any such dispute is not
resolved within thirty (30) days after notice thereof is given to any Party,
the affected Parties shall submit the dispute to an Independent Accounting
Firm for resolution, which resolution shall be final, binding and conclusive
on such 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 and Buyer. Any payment required to be
made as a result of the resolution by the Independent Accounting Firm of any
such dispute shall be made within five (5) Business Days after such
resolution, together with any interest determined by the Independent
Accounting Firm to be appropriate.

            (e) As reasonably requested by Seller, Buyer shall cooperate with
Seller in effectuating the transactions contemplated by this Agreement in such
a manner as to qualify for deferred like-kind exchange treatment under Section
1031 of the Code ("Like-Kind Exchange") (including the transfer of cash and
other property and the assignment of this Agreement to one or more qualified
intermediaries and the execution of appropriate documentation). In such event,
Seller shall be responsible, and shall indemnify Buyer, for any Transfer Taxes
incurred by Buyer as a result of effectuating such Like-Kind Exchange to the
extent that the amount of such Transfer Taxes exceeds the amount of Transfer
Taxes that the Buyer would have otherwise incurred had the transactions not
been effectuated as a Like-Kind Exchange (and all such amounts shall be
computed on an after-Tax basis). At Buyer's request, Seller shall promptly
provide Buyer copies of all documents prepared by Seller, including proposed
agreements, relating to the Like-Kind Exchange and shall give Buyer a
reasonable opportunity to promptly comment on such documents and agreements.

                                       37
<PAGE>

            (f) To the extent that any Party receives a Tax refund or credit
with respect to a Tax that was paid or incurred by the other Party, such
receiving Party shall promptly pay the amount of such Tax refund or credit to
the other Party.

      6.6 Advice of Changes. Prior to the Closing, each Party shall advise the
other in writing with respect to any matter arising after the date of this
Agreement of which that Party obtains Knowledge and which, if existing or
occurring on or prior to the date of this Agreement, would have been required
to be set forth in this Agreement, including any of the Schedules hereto.
Seller shall, from time to time prior to the Closing, promptly supplement or
amend the Schedules to this Agreement with respect to (a) any matter that
existed as of the date of this Agreement and should have been set forth or
described in any of the Schedules hereto and (b) any matter hereafter arising
which, if existing as of the date of this Agreement, would have been required
to be set forth or described in any of the Schedules hereto in order to make
any representation or warranty set forth in this Agreement true and correct as
of such date; provided, however, that, with respect to clause (a) above, any
such supplemental or amended disclosure shall not be deemed to have been
disclosed as of the date of this Agreement unless expressly consented to in
writing by Buyer; and provided further, that, with respect to clause (b)
above, any such supplemental or amended disclosure shall, for purposes of this
Agreement, including for purposes of determining whether the conditions to
Closing set forth in Article VII are satisfied, be deemed to have been
disclosed as of the date of this Agreement.

      6.7 Risk of Loss.

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

            (b) Notwithstanding any provision hereof to the contrary, subject
to Section 9.1(g), if, before the Closing Date, all or any portion of the

casualty, Seller shall notify Buyer promptly in writing of such fact, and (x)
in the case of a condemnation or taking, Seller shall assign or pay, as the
case may be, any net proceeds thereof to Buyer at the Closing and (y) in the

Notwithstanding the foregoing, if such condemnation, taking, damage or
destruction results in a Material Adverse Effect, Buyer and Seller shall
negotiate to resolve the loss resulting from such condemnation, taking, damage
or destruction (and such negotiation shall include the negotiation of a fair
and equitable adjustment to the Purchase Price). If no such resolution can be
agreed upon within ninety (90) days after Seller has notified Buyer of such
loss, then Buyer, on the one hand, or Seller, on the other hand, may terminate
this Agreement pursuant to Section 9.1(g).

such Emission Allowances that are to be allocated or issued by a Governmental
Authority in the future. Buyer and Seller further acknowledge and agree that
such actions may be required before, on or after the Closing Date.

                                 ARTICLE VIII

                        INDEMNIFICATION AND ARBITRATION

      8.1 Indemnification.

            (a) From and after the Closing Date, Buyer shall indemnify, defend
and hold harmless Seller and its Representatives (each, a "Seller's
Indemnitee"), from and against any and all claims, demands, suits, losses,
liabilities, penalties, damages, obligations, payments, costs and expenses
(including reasonable attorneys' fees and expenses in connection therewith)
(each, an "Indemnifiable Loss"), asserted against or suffered by any Seller's
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, (ii)
the Assumed Liabilities, (iii) any Inspection or (iv) any Third-Party Claim
against any Seller's Indemnitee in connection with Buyer's ownership, lease,
maintenance or operation of any of the Purchased Assets on or after the
Closing Date (other than to the extent such Third-Party Claim constitutes an
Excluded Liability); provided, however, that Buyer shall be liable to Seller
pursuant to clause (i) of this Section 8.1(a) only for Indemnifiable Losses
for which any Seller's Indemnitee gives written notice to Buyer (setting forth
with reasonable specificity the nature and amount of the Indemnifiable Loss)
during the period for which such covenants or agreements survive the Closing
in accordance with Section 10.6.

            (b) From and after the Closing, Seller shall indemnify, defend and
hold harmless Buyer and its Representatives (each, a "Buyer's Indemnitee" and,
together with Seller's Indemnitees, an "Indemnitee"), from and against any and
all Indemnifiable Losses asserted against or suffered by any Buyer's
Indemnitee relating to, resulting from or arising out of (i) any breach by
Seller of any covenant or agreement of Seller set forth in this Agreement or
(ii) the Excluded Liabilities; provided, however, that Seller shall be liable
pursuant to clause (i) of this Section 8.1(b) only for Indemnifiable Losses
for which any Buyer's Indemnitee gives written notice to Seller (setting forth
with reasonable specificity the nature and amount of the Indemnifiable Loss)
during the period for which such covenants or agreements survive the Closing
in accordance with Section 10.6.

                                       42
<PAGE>

            (c) In furtherance, and not in limitation, of the provisions set
forth in Section 8.1(a), Buyer, for itself and on behalf of its
Representatives, hereby irrevocably releases, holds harmless and forever
discharges Seller from any and all Indemnifiable Losses of any kind or
character, whether known or unknown, contingent or accrued, arising under or
relating to Environmental Laws, or relating to any claim in respect of any
Environmental Condition or Hazardous Substance, whether based on common law or
Environmental Laws relating to the Purchased Assets, other than such
Liabilities which have been retained by Seller hereunder (collectively,
"Environmental Claims"). In furtherance of the foregoing, Buyer, for itself
and on behalf of its Representatives, hereby irrevocably waives any and all
rights and benefits with respect to such Environmental Claims that it now has,
or in the future may have conferred upon it by virtue of any Law 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, Buyer
hereby acknowledges that it is aware that factual matters now unknown to it
may have given, or hereafter may give, rise to Environmental Claims that are
presently unknown, unanticipated and unsuspected, and Buyer further agrees
that this release set forth in this Section 8.1(c) has been negotiated and
agreed upon in light of that awareness, and Buyer, for itself and on behalf of
its Representatives, nevertheless hereby intends irrevocably to release, hold
harmless and forever discharge Seller from all such Environmental Claims.

            (d) The rights and remedies of Seller and Buyer set forth in this
Article VIII are exclusive and in lieu of any and all other rights and
remedies which Seller and Buyer may have under this Agreement, under
applicable Law, whether at common law or in equity, including for declaratory,
injunctive or monetary relief, in each case, with respect to any Indemnifiable
Loss.

            (e) Notwithstanding anything to the contrary herein, no Person
(including an Indemnitee) shall be entitled to recover from any other Person
(including any Party hereto required to provide indemnification under this
Agreement (an "Indemnifying Party")) any amount in excess of the actual
compensatory damages, court costs and reasonable attorneys' fees suffered by
such Party. Buyer and Seller hereby irrevocably waive any right to recover
punitive, special, exemplary and consequential damages arising in connection
with or with respect to this Agreement (other than with respect to
indemnification for a Third-Party Claim).

            (f) Any Indemnitee shall use Commercially Reasonable Efforts to
mitigate all losses, damages and the like relating to a claim under the
indemnification provisions in this Section 8.1, including availing itself of
any defenses, limitations, rights of contribution, claims against third
Persons and other rights at law or equity. For purposes of this Section
8.1(f), 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, in
addition to its other obligations hereunder, the Indemnifying

                                       43
<PAGE>

Party shall reimburse the Indemnitee for the Indemnitee's reasonable
expenditures in undertaking the mitigation.

      8.2 Defense of Claims.

            (a) If any Indemnitee receives notice of the assertion of any
claim or of the commencement of any suit, action or proceeding made or brought
by any Person who is not an Indemnitee (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 no event later than ten (10) Business 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 incurred by the Indemnitee. The Indemnifying Party shall
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. If
an Indemnifying Party elects not to assume the defense of any Third-Party
Claim, the Indemnitee may defend, compromise or settle such Third-Party Claim
with counsel selected by it, provided that, without the prior written consent
of the Indemnifying Party, the Indemnitee shall not agree to the entry of any
judgment with respect to, or any compromise or settlement of, any Third-Party
Claim, which judgment, compromise or settlement does not include the
unconditional release of the Indemnifying Party.

            (b) If, within twenty (20) Business Days after an Indemnitee gives
written notice to the Indemnifying Party of any Third-Party Claim, such
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), then the Indemnifying Party shall not be liable
for any costs, fees or expenses subsequently incurred by the Indemnitee in
connection with the defense, compromise or settlement thereof.

            (c) Subject to Section 8.3, any claim by an Indemnitee on account
of an Indemnifiable Loss which does not constitute a Third-Party Claim (a
"Direct Claim") shall be asserted by giving the Indemnifying Party reasonably
prompt written notice thereof, in no event later than twenty (20) Business
Days after the Indemnitee becomes aware of such Direct Claim, stating the
nature of such claim in reasonable detail and indicating the estimated amount,
if practicable, of such Indemnifiable Loss and the Indemnifying Party shall
have a period of twenty (20) Business Days within which to respond to such
Direct Claim. If the Indemnifying Party fails to respond during such twenty
(20) Business Day period, the Indemnifying Party shall be deemed to have
accepted such claim and, subject to this Article VIII, shall promptly
reimburse the Indemnitee for the Indemnifiable Losses set forth in the
Indemnitee's notice.

            (d) 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
to the extent that, as a result of such

                                       44
<PAGE>

failure, the Party which was entitled to receive such notice was actually
prejudiced as a result of such failure.

      8.3 Arbitration.

            (a) Notwithstanding any provision hereof to the contrary, in the
event of any dispute between Seller and Buyer arising after the Closing
(whether relating to facts, events or circumstances occurring or existing
prior to, on or after the Closing Date) and relating to or arising out of any
provision of this Agreement (other than disputes arising under Section 2.3,
2.4, 3.2, 3.3, 3.4, 6.5 or 8.1(a)(ii)), the Party asserting such dispute shall
give written notice to the other of the fact that a dispute has arisen
pursuant hereto. Such notice shall include (i) a statement setting forth in
reasonable detail the facts, events, circumstances, evidence and arguments
underlying such dispute and (ii) proposed arrangements for a meeting to
attempt to resolve the dispute to be held within sixty (60) days after such
notice is given. Within thirty (30) days after such notice is given, the other
Party hereto shall submit to the Party giving such notice a written summary
responding to such statement of facts, events, circumstances, evidence and
arguments contained in the notice and an acceptance of or proposed alternative
to the meeting arrangements set forth in the initial notice.

            (b) The chief executive officers (or any other executive officer
or officers directly reporting to, and duly designated by, such chief
executive officers) of each of the Parties shall meet at a mutually acceptable
time and place to attempt to settle any dispute in good faith; provided,
however, that such meeting shall be held at the principal offices of the Party
receiving the notice of dispute unless otherwise agreed; and provided further,
that any such meeting shall be held no later than sixty (60) days after the
written notice of dispute is given pursuant to Section 8.3(a). Each Party
shall bear its own costs and expenses with respect to preparation for,
attendance at and participation in such meeting.

            (c) In the event that (i) a meeting has been held in accordance
with Section 8.3(b), (ii) any such dispute of the kind referred to in Section
8.3(a) shall not have been resolved at such meeting and (iii) the aggregate
amount in dispute exceeds $100,000, then either Party may submit such dispute
to binding arbitration pursuant to the Commercial Arbitration Rules of the
American Arbitration Association (the "Commercial Arbitration Rules"). In the
event that such dispute is submitted to arbitration pursuant to the Commercial
Arbitration Rules, then the arbitration tribunal shall be composed of three
arbitrators (one arbitrator selected by each Party within thirty (30) days
after the meeting held in accordance with Section 8.3(b) with the third
selected by the other two arbitrators or, in the absence of agreement between
them, the American Arbitration Association), the venue of the arbitration
shall be Wilmington, Delaware, the language of the arbitration shall be
English and the arbitration shall commence no later than sixty (60) days after
the meeting held in accordance with Section 8.3(b). The decision, judgment and
order of the arbitration tribunal shall be final, binding and conclusive as to
the Parties and their respective Representatives, and may be entered in court
of competent jurisdiction. Other than the fees and expenses of the
arbitrators, which shall be shared equally by the Parties, each Party shall

                                       45
<PAGE>

bear its own costs and expenses (including attorneys' fees and expenses)
relating to the arbitration.

      8.4 Remediation of Matters Covered in Section 2.4(g). With respect to
the Liabilities as to which Seller has retained responsibility for Remediation
pursuant to Section 2.4(g):

            (a) Seller shall have the right, but not the obligation, to
control the management of any Remediation covered by this Section 8.4. With
respect to Liabilities that are potentially covered by this Section 8.4,
Seller must notify Buyer within thirty (30) days of receipt of notice of
Buyer's claim for indemnification for such matter that it intends to undertake
responsibility for said Remediation. Prior to a determination by Seller that
it will undertake Remediation pursuant to this Section 8.4, Buyer shall, at
Seller's expense, take only those actions necessary to comply with applicable
Environmental Laws or as required by Governmental Authorities or address
conditions that pose an immediate and acute environmental or health risk
(unless additional actions are approved by Seller, such approval not to be
unreasonably withheld or delayed).

            (b) Seller shall comply with all applicable Laws, including all
applicable Environmental Laws, with respect to its performance pursuant to
this Section 8.4. Seller shall promptly provide copies to Buyer of all
notices, correspondence, draft reports, submissions, work plans, and final
reports and shall give Buyer a reasonable opportunity (at Buyer's own expense)
to promptly comment on any submissions Seller intends to deliver or submit to
the appropriate regulatory body prior to said submission. Buyer may, at its
own expense, hire its own consultants, attorneys or other professionals to
monitor the investigation or remediation, including any field work undertaken
by Seller, and Seller shall provide Buyer with the results of all such field
work. Notwithstanding the foregoing, Buyer shall not take any actions that
shall unreasonably interfere with Seller's performance of the Remediation.
Seller shall undertake any such work required herein in a manner designed to
minimize any disruption, to the greatest extent possible, with the conduct of
operations at the property. Buyer shall allow Seller reasonable access to
conduct any of the work contemplated herein and shall fully cooperate with
Seller in the performance of the Remediation, including providing Seller with
reasonable access to employees and documents as necessary.

            (c) If Seller declines to undertake the performance of a
Remediation hereunder, Buyer shall be entitled to control the investigation
and remediation. Buyer shall promptly provide copies to Seller of all notices,
correspondence, draft reports, submissions, work plans, and final reports and
shall give Seller a reasonable opportunity (at Seller's own expense) to
promptly comment on any submissions Buyer intends to deliver or submit to the
appropriate regulatory body prior to said submission. Seller may, at its own
expense, hire its own consultants, attorneys or other professionals to monitor
the Remediation, including any field work undertaken by Buyer, and Buyer shall
provide Seller with the results of all such field work. Notwithstanding the
foregoing, Seller shall not take any actions that shall unreasonably interfere
with Buyer's performance of the Remediation. Seller's decision to allow Buyer
to undertake

                                       46
<PAGE>

Remediation hereunder shall not limit or affect Seller's obligation to indemnify
Buyer for said investigation and remediation as otherwise provided in this
Agreement.

            (d) Without regard to whether Buyer or Seller is conducting a
Remediation pursuant to this Section 8.4, the Parties agree that such
Remediation will be conducted in a reasonable manner and consistent with the
use of the Site in question as an electric generating station. Without
limiting the foregoing, the Parties agree that they will conduct any such
Remediation so that the Remediation Standard that is applicable to the Site is
the least stringent Remediation Standard that would apply to the Site based on
the current use of the Site, and Buyer furthermore covenants that it will
accept a deed restriction or other reasonable institutional or engineering
controls, if such mechanisms will (A) allow the Remediation of the Site to be
completed in the least cost manner in compliance with applicable Environmental
Law and (B) not unreasonably interfere with operations at the Site.
Notwithstanding the foregoing, if Buyer determines at or after the Closing
that it desires a Remediation such that the Site is remediated to a more
stringent Remediation Standard, it may do so, provided, that (x) if Seller is
managing a Remediation pursuant to this Section 8.4, it has the right, to the
extent permitted by Law, to cease conduct of the Remediation and request Buyer
to assume the conduct of the Remediation and (y) notwithstanding which of the
Parties conducts the Remediation, Buyer shall be liable for the costs and
expenses associated with the Remediation to the extent those costs and
expenses exceed those that would be associated with a Remediation Standard as
determined by the previous sentence.


                                  ARTICLE IX

                                  TERMINATION

      9.1 Termination.

            (a) This Agreement may be terminated at any time prior to the
Closing by mutual written consent of the Parties.

            (b) This Agreement may be terminated by Seller, on the one hand,
or Buyer, on the other hand, upon written notice to the other Party, (i) at
any time prior to the Closing if any 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 nonappealable; (ii) at any time prior to the Closing if
any Law shall have been enacted or issued by any Governmental Authority which,
directly or indirectly, prohibits the consummation of the transactions
contemplated by this Agreement or by any Additional Agreement; or (iii) at any
time after the first anniversary of the date of this Agreement if the Closing
shall not have occurred on or before such date; provided, however, that the
right to terminate this Agreement under this Section 9.1(b)(iii) shall not be
available to any Party whose breach of this Agreement has caused, or resulted
in, the failure of the Closing to occur on or

                                       47
<PAGE>

before such date; and provided, further, that if on such date, the conditions to
the Closing set forth in Section 7.1(c) or 7.2(c) shall not have been satisfied
but all other conditions to the Closing shall be satisfied or shall be capable
of being satisfied, then no Party shall be entitled to terminate this Agreement
prior to the date which is 180 days after the first anniversary of the date of
this Agreement.

            (c) This Agreement may be terminated by Buyer, upon written notice
to Seller, if any of Buyer's 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), and such denial was not caused by or the result
of a breach of this Agreement by Buyer.

            (d) This Agreement may be terminated by Seller, upon written
notice to Buyer, if any of the Seller's Required Regulatory Approvals, the
receipt of which is a condition to the obligation of Seller 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), and such denial was not caused by or the result
of a breach of this Agreement by Seller.

            (e) Except as otherwise provided in this Agreement, this Agreement
may be terminated by Buyer, upon written notice to Seller, if there has been a
breach by Seller of any covenant, agreement, representation or warranty
contained in this Agreement which has had a Material Adverse Effect and such
breach is not cured by the earlier of the Closing Date or the date thirty (30)
