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

            (a) Any Liabilities of Seller in respect of any Excluded Assets
or other assets of Seller which are not Purchased Assets, except to the

Buyer's ownership, lease, maintenance or operation of the Purchased Assets;

            (g) Liability for Remediation of Environmental Conditions at,
on, under or migrating from, the Purchased Assets, but only to the extent

Seller for a violation of Environmental Laws by Seller; (ii) Seller's
conviction, guilty plea or plea of nolo contendere was based on Seller's
intentional and willful wrongful actions; and (iii) Seller's conviction,

Seller has received written notice from a Governmental Authority on or
before the sixth anniversary of the 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 to persons or property or damage to natural resources (whether or
not such loss, injury or damage arose or was made manifest before the

                                       19
<PAGE>

or the arrangement of such activities, in connection with the ownership, lease,
maintenance or operation of the Purchased Assets, at any Off-Site Location,
prior to the Closing Date; provided that, for purposes of this Section, "Off-
Site Location" does not include any location to which Hazardous Substances
disposed of or Released at the Purchased Assets have migrated; and

            (j) Any Liability under or related to Environmental Laws or the
common law arising as a result of or in connection with the ownership,
lease, 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 Excluded Assets or Excluded Liabilities, and Buyer agrees
to cooperate in connection therewith to the extent Seller reasonably
requests; provided, however, that Buyer shall not be required to incur 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 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.

                                       20
<PAGE>

            (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 $113,136,000
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 $113,136,000 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). 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.

                                       21
<PAGE>

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.


      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

                                       22
<PAGE>

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 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).

                                       23
<PAGE>

            (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;

and instruments contemplated hereby;

            (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:

of Buyer, of resolutions authorizing the execution and delivery of this

<PAGE>

            (f) All such other permits, agreements, documents, instruments
and writings as shall, in the reasonable opinion of Seller and its counsel,
be 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 Date pursuant to this Agreement or otherwise reasonably required in
connection herewith.

      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

            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 the
ACE Related Purchase Agreements to consummate the transactions contemplated
thereby have been satisfied or, to the extent permitted by applicable Law,
waived, but, for any reason, the transactions contemplated by this
Agreement and the DP&L Related Purchase Agreement cannot be consummated
simultaneously therewith, then the Parties shall, at Buyer's option and in
its sole discretion, consummate the transactions contemplated by the ACE
Related Purchase Agreements; provided, however, that nothing contained in
this Section 3.9 shall be construed as relieving Buyer of any of its
obligations under this Agreement or the DP&L Related Purchase Agreement, as
set forth therein.


                                 ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF SELLER

                                       26
<PAGE>

      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
States of Delaware and Virginia 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
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.

                                       27
<PAGE>

            (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
policies of fire, liability, workers' compensation and other forms of
insurance owned or held by, or on behalf of, Seller and insuring any
Purchased Assets are in full force and effect, all premiums with respect
thereto covering all periods up to and including the date hereof have been
paid (other than retroactive premiums which may be payable with respect to
comprehensive general liability and workers' compensation insurance
policies), and no written notice of cancellation or termination has been

      5.1 Organization; Qualification. Buyer is a corporation duly
organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite 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 of this Agreement and each such

<PAGE>

contemplated hereby or thereby have been duly and validly authorized by all
necessary corporate action required on the part of Buyer. This Agreement has
been duly and validly executed and delivered by Buyer and, subject to the
receipt of Buyer's Required Regulatory Approvals, this Agreement constitutes,
and upon the execution and delivery by Buyer of each Additional Agreement to
which it is a party, each such Additional Agreement will constitute, the legal,
valid and binding obligation of Buyer, enforceable against Buyer 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).

      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
execution and delivery by Buyer of this Agreement or the Additional
Agreements to which it is a party nor the consummation by Buyer 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 (or other similar governing documents) of Buyer or
any of its Subsidiaries; (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 Buyer, any such Subsidiary or any of
their respective properties and 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, materially impair Buyer's ability to consummate the transactions
contemplated hereby or by any Additional Agreement, or to perform its
material obligations hereunder or thereunder (a "Buyer Material Adverse
Effect"); or (iii) constitute violations of any Law, order, judgment or
decree applicable to Buyer or any of its Subsidiaries, which violations,
individually or in the aggregate, would have a Buyer Material Adverse
Effect.

            (b) Except for consents, approvals, filings and notices (i)
required under the HSR Act or (ii) set forth on Schedule 5.3(b) (the
consents, approvals, filings and notices referred to in clause (ii) of this
sentence are collectively referred to herein as the "Buyer'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 Buyer of this Agreement and the Additional Agreements to which it is a
party or the consummation by Buyer of the transactions contemplated hereby
or thereby, other than such consents, approvals, filings or notices, which,
if not obtained or made, would not have a Buyer Material Adverse Effect.

      5.4 Buyer's Permits. Buyer holds, and is in compliance with, or on or
prior to the Closing Date will hold, and from and after the Closing Date
will comply with, all permits, certificates, licenses and other
authorizations of all Governmental Authorities that Buyer requires

"Buyer's Permits").

      5.5 Availability of Funds. Buyer has sufficient funds and lines of
credit available to it, or has received binding written commitments from
creditworthy financial institutions, true and correct copies of which have
been provided to Seller, to permit Buyer on the Closing Date to pay the
Purchase Price, all other amounts payable by Buyer hereunder or under any
Additional Agreement, and all fees and expenses incurred by Buyer in
connection with the transactions contemplated hereby and by the Additional
Agreements, and to permit Buyer to timely pay or perform all of its other
obligations (including its obligations pursuant to Article VIII) under this
Agreement and the Additional Agreements.

      5.6 Financial Statements. Buyer has provided Seller with true and
correct copies of its balance sheet, income statement and statement of
changes in cash flows of Buyer for each of its last three completed fiscal
years, together with the related reports of its independent accountants,
PricewaterhouseCoopers LLP, and for its most recently completed fiscal
quarter ("Buyer's Financial Statements"). Such Buyer's Financial Statements
have been prepared in accordance with United States generally accepted
accounting principles consistently applied and fairly reflect, in all
material respects, the financial position, results of operations and cash
flow of Buyer at and for the periods therein.

      5.7 Legal Proceedings. There are no suits, actions or proceedings
pending or threatened against Buyer by or before any Governmental
Authority, which would, individually or in the aggregate, have a Buyer
Material Adverse Effect or would materially impair such Buyer's ability to

orders or decrees of any Governmental Authority which would, individually

                          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 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

                                       33
<PAGE>

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):

                  (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

                                       34
<PAGE>

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
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 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

                                       35
<PAGE>

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 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.

                                       36
<PAGE>

            (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.

            (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

                                       37
<PAGE>

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 Purchased Assets is (i) condemned or taken by eminent domain or is
the subject of a pending or threatened condemnation or taking which has not
been consummated, or (ii) materially damaged or destroyed by fire or other
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 case of a fire or other casualty, Seller shall either restore such
damage or assign the insurance proceeds therefor to Buyer at the Closing.
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).

      6.8 PJM; MAAC. From and after the Closing Date, Buyer shall maintain
membership in good standing in PJM and MAAC, and shall submit to the
governance of the independent system operator established and administered
under the PJM Agreement.

      6.9 Emission Allowances. Buyer and Seller shall take all necessary
actions, including executing any required forms or providing appropriate
notices to Governmental Authorities, in a

                                       38

timely fashion, to ensure that (i) Buyer will obtain all, or the rights to all,
(A) Emission Allowances that are to be transferred to it pursuant to Section
2.1(f) and as set forth on Schedule 2.1(f), including the right to receive such
Emission Allowances that are to be allocated or issued by a Governmental
Authority in the future, and (B) Excess Emission Allowances that are to be
transferred to it pursuant to Section 2.1(g) and as set forth on Schedule 2.1(g)
and (ii) Seller will retain or obtain all, or the rights to all, Emission
Allowances that are defined as Excluded Assets pursuant to Section 2.2(o),
including the right to receive 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.

            (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

                                       42
<PAGE>

(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
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

                                       43
<PAGE>

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 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,

                                       44
<PAGE>

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 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

                                       45
<PAGE>

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 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

                                       46
<PAGE>

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 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

                                       47
<PAGE>

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) days after receipt by Seller of notice
specifying in reasonable detail the nature of such breach, unless Buyer
shall have previously waived such breach.

            (f) Except as otherwise provided in this Agreement, this
