shall have been satisfied

                                       22
<PAGE>

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.

               (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 $508,463,000
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 each 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 $508,463,000 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

                                       23
<PAGE>

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. 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

                                       24

with reasonable assistance in the event of an examination, audit or other

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

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.

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

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

possession of Seller 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, and (C)
Seller need not supply Buyer with any information which Seller is under a
legal or contractual obligation not to supply. 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 Wholly Owned
Station, and Seller shall only furnish or provide such access to Employee
personnel records and files to the extent permitted by applicable Law and
to the extent that such records and files pertain to the following: (i)
skill and development training; (ii) seniority histories; (iii) salary and
benefit information; (iv) Occupational, Safety and Health Administration
reports; and (v) active medical restriction forms.

               (b) All information furnished to or obtained by Buyer and
Buyer's Representatives pursuant to this Section 6.2 shall be Proprietary
Information and shall be kept confidential in accordance with the terms of
the Confidentiality Agreement. Nothing in this Section 6.2 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, including
all Transferred Employee Records, 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

                                       37
<PAGE>

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 6.2(c).
If the Party in possession of such books and records shall desire to dispose of
any books and records upon or prior to the expiration of such seven-year period,
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.

        6.3 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.

        6.4 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 6.4(a):

                                       38
<PAGE>

                      (i) In the event that any Purchased Asset shall not
have been conveyed to Buyer at the Closing, Seller shall, subject to
Section 6.4(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.

        6.5 Consents and Approvals. Without limiting the generality of
Section 6.4(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
DPSC, the MPSC, 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. In furtherance of the foregoing, the Parties shall,
prior to January 31, 2000, agree upon a form of Power Purchase Agreement,
substantially to the effect of the term sheet set forth in Exhibit G
hereto. 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

                                       39
<PAGE>

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
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 6.5(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.

        6.6 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 Delaware and
Maryland and (ii) transfer Tax on conveyances of interests in real property
imposed by Delaware and Maryland) 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

                                       40
<PAGE>

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.

               (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 6.6(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 6.6, 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.

                                       41
<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.

        6.7 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.

        6.8 Employees.

               (a) Buyer shall offer employment, effective as of the
Closing Date, to all employees of Seller employed at the Wholly Owned
Stations as of the Closing Date who are covered by any IBEW Collective
Bargaining Agreement, including those employees absent from active service
due to illness or leave of absence (the "Union Employees"), pursuant to and
in accordance with the applicable IBEW Collective Bargaining Agreement and
applicable Law. Each Union Employee who becomes employed by Buyer pursuant
to this Section 6.8(a) is referred to herein as a "Transferred Union
Employee". Each Transferred Union Employee shall receive on or before the
date that is thirty (30) days after the Closing Date a $4,500 lump sum
signing bonus from Seller, less applicable withholdings.

               (b) Any Union Employee who refuses an offer of employment
from Buyer shall be treated by Seller as a terminated employee under the
terms of the IBEW Collective Bargaining Agreements.

               (c) Schedule 6.8(c) sets forth the collective bargaining
agreements and amendments and supplements thereto to which Seller is a
party with the IBEW in connection with the Wholly Owned Stations (as so
amended and supplemented, "IBEW Collective Bargaining Agreements").
Transferred Union Employees shall retain their seniority and receive full
credit for service with Seller and its Affiliates in connection with
entitlement to vacation and all

                                       42
<PAGE>

other benefits and rights under the IBEW Collective Bargaining Agreements to
which seniority or years of service are applicable. On the Closing Date, Buyer
shall assume the IBEW Collective Bargaining Agreements for the duration of their
respective terms as they relate to Transferred Union Employees and other
employees to be employed by Buyer or its Affiliates at the Wholly Owned Stations
in positions covered by the IBEW Collective Bargaining Agreements, and Buyer
shall comply with all applicable obligations under the IBEW Collective
Bargaining Agreements. Buyer shall establish a pension plan and benefit programs
for the duration of the remaining term of the IBEW Collective Bargaining
Agreements which are substantially equivalent to Seller's plans and programs and
shall provide, with respect to each benefit and coverage thereunder, at least
the same level of benefits and coverage as Seller's plans and programs as of the
Closing Date, all in accordance with the IBEW Collective Bargaining Agreements.
Buyer shall recognize the IBEW as the collective bargaining agent for the
Transferred Employees in positions covered by the IBEW Collective Bargaining
Agreements.

               (d) Buyer shall comply with the provisions of ss. 1016(b) of
the Delaware Electric Utility Restructuring Act of 1999, and similar Laws
in other jurisdictions, with respect to all Union Employees covered by the
IBEW Collective Bargaining Agreements.

               (e) Buyer may, but, except as set forth below, shall not be
required to, offer employment, effective as of the Closing Date, to certain
employees of Seller, to be agreed to by Buyer and Seller, who are (i)
employed at the Wholly Owned Stations (other than Union Employees) or (ii)
corporate support personnel identified by Seller within thirty (30) days
after the date hereof (collectively, the "Non-Union Employees" and,
together with Union Employees, "Employees"), provided that, Buyer shall
hire its initial complement of management personnel from among the
Non-Union Employees. Within ninety (90) days after the date hereof, Buyer
shall notify Seller as to the identity of those Non-Union Employees to whom
it intends to offer employment, provided that, during such period, Seller
shall, upon reasonable notice and to the extent not disruptive to the
operation of the Purchased Assets, provide Buyer with reasonable access to
Non-Union Employees and, to the extent permitted by applicable Law, their
personnel records. Each Non-Union Employee who becomes employed by Buyer
pursuant to this Section 6.8(e) shall be referred to herein as a
"Transferred Non-Union Employee" and, together with Transferred Union
Employees, the "Transferred Employees." Each Transferred Non-Union Employee
shall receive on or before the date that is thirty (30) days after the
Closing Date a lump sum signing bonus from Seller equal to 10% of such
Transferred Non-Union Employee's base salary in the most recent calendar
year ending prior to the Closing, less applicable withholdings. Any offer
of employment to a Non-Union Employee that satisfies all of the following
requirements is referred to herein as a "Qualified Offer":

                      (i) Buyer shall offer such Non-Union Employee
full-time employment with Buyer; provided, however, that nothing herein
shall prevent Buyer from terminating any Transferred Non-Union Employee
following the Closing Date for cause within twelve (12) months after the
Closing and for any reason thereafter.

                                       43
<PAGE>

                      (ii) Buyer shall pay and provide such Transferred
Non-Union Employee annual compensation, bonus and other incentive
opportunities (the "Total Cash Compensation") at a rate equal to at least
85% of such Transferred Non-Union Employee's Total Cash Compensation in the
most recent calendar year ending prior to the Closing.

                      (iii) The location of such Transferred Non-Union
Employee's workplace must be no more than 50 miles from the location of
such Transferred Non-Union Employee's workplace as of immediately prior to
the Closing Date.

                      (iv) Such Transferred Non-Union Employee shall be
eligible to participate in such employee benefit plans, programs and
arrangements of Affiliates of Buyer as are offered to similarly situated
non-union employees of Buyer's operating Affiliates ("Buyer's Benefit
Plans") and shall receive full credit for service with Seller and their
Affiliates for eligibility, vesting and benefits entitlement purposes;
provided, however, that such service shall not be required to be recognized
to the extent that such recognition would result in a duplication of
benefits. Buyer shall cause the Buyer's Benefit Plans to (x) waive all
limitations as to pre-existing condition exclusions and waiting periods
with respect to such Transferred Non-Union Employee under the employee
welfare benefit plans (as such term is defined in Section 3(1) of ERISA) of
Buyer or its Affiliates ("Buyer's Welfare Plans") to the extent such
limitations or waiting periods that were in effect with respect to such
Transferred Non-Union Employees under Seller's employee welfare plans have
been satisfied as of the Closing Date, and (y) provide such Transferred
Non-Union Employee with credit for any co-payments and deductibles paid
prior to the Closing Date in satisfying any deductible or out-of-pocket
requirements under the Buyer Welfare Plans (on a pro rata basis in the
event of a difference in plan years).

               (f) With respect to each Transferred Employee's accrued
benefit (based on service and compensation as of the Closing Date) (the
"Closing Date Benefits"), Seller shall, effective as of the Closing Date,
amend the Conectiv Retirement Plan ("Seller's Pension Plan") to (i)
recognize service with Buyer for purposes of vesting the Closing Date
Benefits in Seller's Pension Plan; (ii) recognize service with Buyer toward
eligibility for receipt of subsidized early retirement and optional benefit
forms with respect to the Closing Date Benefits under Seller's Pension
Plan; (iii) provide that retirement from Buyer's service shall be deemed
retirement from active employment with Seller for purposes of eligibility
for receipt of subsidized early retirement and optional benefit forms with
respect to the Closing Date Benefits under Seller's Pension Plan; and (iv)
provide that Closing Date Benefits cannot commence until the earlier of
such Transferred Employee's actual retirement from Buyer's employment or
attainment of age 65. The pension plan of Buyer ("Buyer's Pension Plan")
shall recognize all prior service with Seller for purposes of vesting and
benefit accrual for Transferred Union Employees (and, at Buyer's election,
Transferred Non-Union Employees), and may offset the Closing Date Benefits
from benefit accruals thereunder. Buyer and Seller shall provide each other
with such records and information as may be necessary or appropriate to
carry out their respective obligations under this Section 6.8(f) for the
purposes of administration of Buyer's Pension Plan and Seller's Pension
Plan.

                                       44
<PAGE>

               (g) As soon as practicable, and in any event within ninety
(90) days after the Closing Date, Buyer shall establish or make available
to Transferred Union Employees a defined contribution pension plan (or
plans) and trust (or trusts) intended to qualify under Sections 401(a) and
501(a) of the Code (such plan or plans referred to as "Buyer's Savings
Plan") in which all Transferred Union Employees shall be eligible to
participate as of the later of the Closing Date or the Buyer's Savings
Plan's Effective Date. Buyer's Savings Plan shall provide for deferral
options and employer matching contributions with respect to the Transferred
Union Employees who are participants in the Conectiv Savings & Investment
Plan and the Atlantic City Electric Co. Savings Plan B (collectively,
"Seller's Savings Plans") as of the Closing Date (such employees, the
"Transferred Savings Employees") that are no less favorable than those
provided as of immediately prior to the Closing Date to the Transferred
Savings Employees under the Seller's Savings Plans (including an
opportunity to make up for any lost deferrals and/or employer matching
contributions that were unavailable because of a delay between the Closing
Date and the effective date of Buyer's Savings Plan). Contributions to the
Seller's Savings Plans with respect to the Transferred Savings Employees
shall cease effective as of the Closing Date. Each Transferred Savings
Employee shall be afforded the option of transferring his or her account
balance into the Buyer's Savings Plan; provided, however, that if Seller is
able to obtain a favorable ruling from the Internal Revenue Service to the
effect that the consummation of the transactions contemplated hereby shall
constitute a sale of substantially all of the assets used in a trade or
business within the meaning of Section 401(k)(10) of the Code, each
Transferred Savings Employee shall be afforded the option of rolling over
his or her account balance into the Buyer's Savings Plan. Such transfers or
rollovers shall satisfy the requirements of Section 414(l) of the Code and
Section 208 of ERISA and shall be in the form of cash or other property, as
Seller and Buyer shall mutually agree prior to such transfer or rollover.
Prior to such transfer or rollover, Buyer will provide Seller with such
documents and other information as Seller shall reasonably request to
assure itself that Buyer's Savings Plan and the trust or trusts established
pursuant thereto (i) provide for voluntary participant after-tax
contributions and (ii) contain participant loan provisions and procedures
necessary to effect the orderly transfer of participant loan balances
associated with the transfer or rollover. In the event that a Transferred
Savings Employee shall elect to leave his or her loan balance in one of
Seller's Savings Plans, Buyer shall cooperate with Seller in providing that
such outstanding loan balance shall be repaid through payroll deductions
from Buyer's payroll. Upon such transfer, Buyer's Savings Plan shall assume
all Liabilities whatsoever with respect to all amounts transferred from
Seller's Savings Plan to Buyer's Savings Plan in respect of the Transferred
Savings Employees and Seller, its Affiliates and Seller's Savings Plan
shall be relieved of all such Liabilities. Notwithstanding anything in this
Section 6.8(g) to the contrary, no such transfer or rollover shall take
place unless and until Seller have received written evidence of the
adoption of Buyer's Savings Plan and the trust (or trusts) thereunder by
Buyer and either (A) a copy of a favorable determination letter issued by
the Internal Revenue Service and satisfactory to Seller's counsel with
respect to Buyer's Savings Plan or (B) an opinion, satisfactory to Seller's
counsel, of Buyer's counsel to the effect that the terms of Buyer's Savings
Plan and its related trust or trusts qualify under Sections 401(a) and
501(a) of the Code. Buyer and Seller shall provide each other with such
records and information

                                       45
<PAGE>

as may be necessary or appropriate to carry out their obligations under this
Section 6.8(g) for the purposes of administration of Buyer's Savings Plan, and
they shall cooperate in the filing of documents required by the transactions
described herein.

               (h) Buyer shall provide severance benefits as set forth on
Schedule 6.8(h) to any Transferred Non-Union Employee (i) who, within the
12-month period immediately following the Closing Date, is terminated by
Buyer or any of its Affiliates other than for cause (as defined on Schedule
6.8(h)) or (ii) with respect to such Persons who have received and accepted
Qualifying Offers, whose terms and conditions of employment with Buyer or
any of its Affiliates are changed during the 12-month period immediately
following the Closing Date, such that such terms and conditions fail to
satisfy all of the requirements set forth in clauses (i) through (iv) of
Section 6.8(e).

               (i) Buyer shall provide notice of and the opportunity to
purchase continuation coverage as required by COBRA to any dependent or
former dependent of a Transferred Union Employee or Transferred Non-Union
Employee who incurs a "qualifying event" (as such term is defined in COBRA)
on or after the Closing Date, or who incurs a "qualifying event" prior to
the Closing Date (other than a termination of employment or death of the
employee) as to which notice is not provided to Seller or Buyer until the
Closing Date or thereafter.

               (j) Seller shall be responsible, with respect to the
Purchased Assets, for performing and discharging all requirements under the
WARN Act and under applicable state and local Laws for the notification of
Union Employees and Non-Union Employees of any "employment loss" (within
the meaning of the WARN Act) which occurs prior to the Closing Date.

               (k) Notwithstanding any contrary provision of this Section
6.8, Buyer may, in its sole discretion and at its expense, choose to offer
a voluntary early retirement or employment termination benefit program to
any group of Union Employees or Non-Union Employees, and such program may
be offered either before or after the Closing. Seller shall (i) cooperate
with Buyer in the design, implementation and administration of such
program; and (ii) provide Buyer with such financial and demographic
information as may be reasonably necessary for such design, implementation
or administration. Buyer acknowledges and agrees that (x) any such program
will require participating Employees to sign a release or waiver as a
condition of receipt of benefits thereunder; (y) such release or waiver
shall be designed and implemented in compliance with the requirements for
valid waivers contained in the Age Discrimination in Employment Act, as
amended, whether or not a participating Employee is protected by such Act;
and (z) such release or waiver shall release Seller, its directors,
officers and subsidiaries, to the same extent that Buyer is released
thereby. Buyer shall reimburse Seller for all reasonable out-of-pocket
costs, fees and expenses incurred at the direction of Buyer in the design,
implementation or administration of such program.

        6.9 Risk of Loss.

                                       46
<PAGE>

               (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).

        6.10 Certain Tax-Exempt Bonds. Buyer acknowledges that Seller
financed the Purchased Assets set forth on Schedule 6.10 with the proceeds
of tax-exempt bonds and that the continuing tax-exempt status of such bonds
depends on the continuing qualifying use of such assets as property used to
abate or control water or atmospheric pollution or contamination by
removing, altering, disposing or storing pollutants, contaminants, water or
heat within the meaning of Section 103(b)(4)(F) of the Code ("Qualifying
Use"). In the event that the use of such assets is changed to a
non-Qualifying Use on or before the maturity date of such bonds, as set
forth on Schedule 6.10, Seller will be required to take certain action to
comply with their obligations to maintain the tax-exempt status of those
bonds. Accordingly, Buyer shall give Seller written notice of any change in
the use of such assets from their current Qualifying Use that occurs before
the maturity date of such bonds, as set forth on Schedule 6.10. Such notice
shall be given at least ten (10) Business Days prior to such change in use.
Notwithstanding the foregoing, Buyer shall not be deemed to have breached
this Section 6.10 if Buyer shall abandon the use of such assets. In the
event that Buyer sells or otherwise transfers such assets on or before the
maturity date of such bonds, as set forth on Schedule 6.10, Buyer shall
give written notice to Sellers at least ten (10) Business Days prior
thereto and Buyer shall require the subsequent owner of such assets to
covenant and agree to comply with the provisions of this Section 6.10. This
covenant shall be included in any recorded deed of transfer of such assets
and, to the extent applicable, will be considered a covenant that runs with
the land.

        6.11 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.

        6.12 Emission Allowances.

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

               (b) Notwithstanding anything in this Agreement to the
contrary, Seller shall provide additional Emissions Allowances to Buyer in
connection with Seller's operation of the Purchased Assets during the year
of the Closing, or Buyer shall transfer Emissions Allowances to Seller, as
follows:

                      (i) SO2 Allowances.

                             (A) Seller shall provide SO2 Allowances to
Buyer based on the following formula: (1) Seller's emissions of SO2 (in
tons) from the units subject to Title IV of the Clean Air Act, 42 U.S.C.ss.
7401, et seq., for the period of the year from and including January 1 of
the year the transaction closes up to, but not including, the Closing Date;
minus (2) Seller's Prorated SO2 Allowances. Seller's Prorated SO2
Allowances shall be determined by adding all of the SO2 Allowances set
forth on Schedule 6.12(b)(i) from and including January 1 of the year in
which the transaction closes up to, but not including, the Closing Date. If
the result of this calculation is less than zero, then Buyer shall transfer
to Seller SO2 Allowances equal to the absolute value of the result of the
calculation set forth in this subsection.

                             (B) If Schedule 6.12(b)(i) is not finalized as
of the date of the execution of this Agreement, Seller hereby covenants to
act in good faith to promptly prepare such schedule. Schedule 6.12(b)(i)
shall be prepared as follows. First, Seller shall develop a projection of
its SO2 emissions for each of the Purchased Assets for each calendar day
for the year 2000. Second, Seller shall take the SO2 Allowances set forth
on Schedule 2.1(f) for each Purchased Asset for the year 2000 and allocate
the SO2 Allowances to each calendar day for the year 2000 so that for each
calendar day, the ratio of said SO2 Allowances to the total number of SO2
Allowances for the Purchased Asset set forth on Schedule 2.1(f) for the
year 2000 shall

                                       48
<PAGE>

equal the ratio of the projected SO2 emissions for each calendar day to the
total number of projected SO2 emissions for the Purchased Asset for the year
2000. When completed, Schedule 6.12(b)(i) shall be a day-by-day schedule of SO2
Allowances for each of the Purchased Assets. The final form and substance of
Schedule 6.12(b)(i) shall be subject to the agreement of Seller and Buyer,
acting in good faith, consistent with the terms of this subsection.

                      (ii) NOx Emission Allowances.

                             (A) Seller shall provide NOx Emission
Allowances to Buyer based on the following formula: (1) Seller's emissions
of NOx (in tons) from the units subject to the NOx Budget Program of New
Jersey for the period of the year from and including May 1 of the year in
which the transaction closes up to, but not including, the Closing Date or
September 30 of said year, whichever comes first; minus (2) Seller's
Prorated NOx Emission Allowances. Seller's Prorated NOx Emission Allowances
shall be determined by adding all of the NOx Emission Allowances set forth
on Schedule 6.12(b)(ii) from and including May 1 of the year the
transaction closes up to, but not including, the Closing Date or September
30 of the year the transaction closes, whichever comes first. If the result
of this calculation is less than zero, than Buyer shall transfer to Seller
an amount of NOx Emission Allowances equal to the absolute value of the
result of the calculation set forth in this subsection.

                             (B) If Schedule 6.12(b)(ii) is not finalized
as of the date of the execution of this Agreement, Seller hereby covenants
to act in good faith to promptly prepare such schedule after the relevant
Governmental Authority finalizes the allocation of NOx Emission Allowances
for the year 2000. Schedule 6.12(b)(ii) shall be prepared as follows.
First, Seller shall develop a projection of its NOx emissions for each of
the Purchased Assets for each calendar day from May 1, 2000 to and
including September 30, 2000. Second, Seller shall take the NOx Emission
Allowances set forth on Schedule 2.1(f) for each Purchased Asset for the
year 2000 and allocate the NOx Emission Allowances to each calendar day for
the period May 1, 2000 to and including September 30, 2000, so that for
each such calendar day, the ratio of said NOx Emission Allowances to the
total number of NOx Emission Allowances for the Purchased Asset set forth
on Schedule 2.1(f) for the year 2000 shall equal the ratio of the projected
NOx emissions for each such calendar day to the total number of projected
NOx emissions for the Purchased Asset for the period May 1, 2000 to and
including September 30, 2000. When completed, Schedule 6.12(b)(ii) shall be
a day-by-day schedule of NOx Emission Allowances for each of the Purchased
Assets. The final form and substance of Schedule 6.12(b)(ii) shall be
subject to the agreement of Seller and Buyer, acting in good faith,
consistent with the terms of this subsection.

                      (iii) If it appears that the Closing of the
transactions contemplated by this Agreement will not occur until after
December 31, 2000, Seller shall prepare schedules that will accomplish the
same purpose as Schedules 6.12(b)(i) and 6.12(b)(ii) for calendar year
2001. Such schedules shall be prepared consistent with the terms of Section
6.12(b).

               (c) Buyer shall deliver to Seller, within thirty (30) days
after Closing, a statement indicating the amount of SO2 Allowances and NOx
Emission Allowances it is owed, or that it owes Seller, in accordance with
the formulas set forth in subsection (b) (the "Statement"). The Statement
shall be based on verified CEMs data for SO2 and NOx and shall include
sufficient information to be evaluated by Seller. In the event that Seller
is in disagreement with the Statement, Seller shall, within ten (10)
calendar days after receipt of the Statement, notify Buyer of such
disagreement setting forth with specificity the nature of such
disagreement. If Seller fails to notify Buyer of all disagreements within
the ten (10) calendar days provided for herein, then the Statement, as
delivered by Buyer pursuant to Section 6.12(c), shall be final, binding and
conclusive on the Parties hereto and the Party owing SO2 Allowances and/or
NOx Emission Allowances to the other Party shall transfer such SO2
Allowances and/or NOx Emission Allowances (or make a payment in lieu of
transferring such Emissions Allowances in accordance with Section 6.12(d)).
If Seller is in disagreement with the Statement and notifies Buyer within
such ten (10) calendar day period, then the Parties shall promptly attempt
to resolve such disagreement by negotiation. If the Parties are unable to
resolve such disagreements within fifteen (15) calendar days following such
notice of disagreement, the Parties shall appoint an Independent Accounting
Firm within thirty (30) calendar days following such notice, which shall
review the Statement and any additional information related to the
Statement submitted by either of the Parties and shall determine the amount
of SO2 Allowances and/or NOx Emission Allowances owed by either of the
Parties. Resolution of any such disagreements shall be made by the
Independent Accounting Firm in a writing addressed to all Parties within
thirty (30) calendar 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 by Buyer and Seller equally.

               (d) The Party or Parties owing SO2 Allowances and/or NOx
Emission Allowances calculated pursuant to this Section shall transfer the
number of SO2 Allowances and/or NOx Emission Allowances owed to the other
Party by no later than thirty (30) days prior to the dates by which Buyer
must have sufficient SO2 Allowances and/or NOx Emission Allowances in its
compliance accounts in order to comply with Title IV of the federal Clean
Air Act or the NOx Budget Programs of Delaware and Maryland. The NOx
Emission Allowances and SO2 Allowances transferred hereunder shall have a
vintage year that is the same as the year the transaction closes or, solely
in the case of SO2 Allowances, a prior vintage year, unless the Party that
is owed such Emission Allowances waives such requirement in writing. If the
Party owing SO2 Allowances and/or NOx Emission Allowances does not or
cannot meet this provision, the other Party shall be entitled to (i)
acquire SO2 Allowances and/or NOx Emission Allowances equal to the number
of additional SO2 Allowances and/or NOx Emission Allowances calculated
pursuant to this Section and (ii) seek compensation from the owing Party
for the cost of acquiring such additional SO2 Allowances and/or NOx
Emission Allowances, respectively ("Allowance Cost"), which shall be
calculated based on the market price for such allowances as of the date
such allowances are purchased; provided, that a Party that is owed SO2
Allowances and/or NOx Emission Allowances and has the right to purchase
such Emission Allowances pursuant to this Section must purchase such
Emission Allowances no later than 180 days after the date(s) by which the
owing Party was to provide such Emission Allowances

                                       50
<PAGE>

to the owed Party, as set forth in the first sentence of this subsection, in
order to be entitled to receive compensation under this subsection. The Party
that has the right to purchase SO2 Allowances and/or NOx Emission Allowances
pursuant to this Section shall also be entitled to receive simple interest at
the Prime Rate on the Allowance Cost, which shall accrue from the date(s)
payment is due as provided in the following sentence through and including the
date of payment by the owing Party. Payment shall be made no later than thirty
(30) days after the owing Party receives an invoice from the owed Party for
compensation, which invoice shall specify the market price of the Emissions
Allowances acquired by the owed Party; provided, that the owing Party shall not
be obligated to make such payment if it disputes the amount of compensation
claimed by the owed Party within fifteen (15) days after receipt of the invoice
from the owed Party. Any disputes concerning the compensation owed to Buyer
under Section 6.12(d) shall be resolved through good faith negotiations between
the Parties. Buyer and Seller shall be obligated to act reasonably to mitigate
the Allowance Cost as set forth herein. Furthermore, notwithstanding anything to
the contrary herein, Seller shall have no obligation to indemnify Buyer for any
penalties or fines or other costs or expenses related to Buyer's failure to
comply with the legal requirements of Title IV of the Clean Air Act or the NOx
Budget Program of New Jersey.

        6.13 Insurance Claims. Seller shall use its Commercially Reasonable
Efforts to assist Buyer in making any claims relating to pre-Closing
periods against any insurance policies of Seller that may provide coverage
related to the Assumed Liabilities.

        6.14 Reimbursement of Certain Metering Expenses. From and after the
Closing, Buyer shall (i) reimburse Seller for reasonable amounts expended
by Seller prior to the later to occur of December 31, 2000 and the date
that is ninety (90) days after the Closing Date in connection with the
installation, renovation or improvement of revenue quality meters and
related equipment up to an aggregate amount of $1,500,000; and (ii)
cooperate with Seller as fully as reasonably possible in order to
facilitate Seller's installation, renovation or improvement of revenue
quality meters and related equipment to the extent that such installation,
renovation or improvement requires that Seller gain access to the Real
Property after the Closing Date.

Section 10.6.

               (b) From and after the Closing, Seller shall indemnify,

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

                                       55
<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

                                       56
<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,

                                       57
<PAGE>

3.2, 3.3, 3.4, 6.6 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 Sections 2.4(g) and 2.4(n).
With respect to the Liabilities as to which Seller has retained
responsibility for Remediation pursuant to Section 2.4(g) or 2.4(n):

               (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 the Liabilities described in

                                       58
<PAGE>

Schedule 2.4(n), Seller shall notify Buyer at the Closing whether it intends to
control the management of the Remediation after the Closing. As for other
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 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

                                       59
<PAGE>

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.

                                TERMINATION

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 denied (and a
petition for rehearing or refiling of an application initially denied

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
Agreement may be terminated by Seller, upon written notice to Buyer, if
there has been a material breach by Buyer 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 Buyer of notice
specifying in reasonable detail the nature of such breach, unless Seller

               (g) This Agreement may be terminated by Seller, on the one
hand, or Buyer, on the other hand, upon written notice to the other Party,
in accordance with the provisions of Section 6.9(b), provided that the
Party seeking to so terminate shall have complied with its obligations
under Section 6.9.

        9.2 Effect of Termination. Upon termination of this Agreement prior
to the Closing pursuant to Section 9.1, this Agreement shall be null and
void and of no further force or effect (except that the provisions set
forth in Section 6.3, this Section 9.2 and Article X, and the
Confidentiality Agreement, shall remain in full force and effect in
accordance with their respective terms); and no Party shall have any
further Liability under this Agreement (other than for any wilful breach of
its obligations hereunder).

        10.9 Assignment. This Agreement shall be binding upon and inure to
the benefit of the Parties and their respective successors and permitted
assigns, but neither this Agreement nor any of the rights, interests,

including by operation of law, without the prior written consent of the

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

extent caused by the acts or omissions of Buyer or Buyer's ownership,
lease, maintenance or operation of the Purchased Assets.

                                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

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.

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

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.

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.

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.

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
received by Seller with respect to any such policy which was not replaced
on substantially similar terms prior to the date of such cancellation or

compliance with applicable Environmental Laws, as would not, individually
or in the aggregate, materially impair the ability of Buyer to operate the
Purchased Assets after the Closing in the manner operated by Seller on the
date hereof.

                                       28

            (c) Seller has not entered into or agreed to any consent decree
or order under any Environmental Law relating to the Purchased Assets, and

                                       29
<PAGE>

            (c) Except as set forth on Schedule 4.9(a), there is not under
any Seller's Agreement set forth on Schedule 4.9(a) any default or event

Effect"); or (iii) constitute violations of any Law, order, judgment or
decree applicable to Buyer or any of its Subsidiaries, which violations,

Effect.

            (b) Except for consents, approvals, filings and notices (i)

                          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

            (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
<PAGE>

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.

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

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

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

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
Agreement may be terminated by Seller, upon written notice to Buyer, if
there has been a material breach by Buyer 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 Buyer of notice
specifying in reasonable detail the nature of such breach, unless Seller

            (g) This Agreement may be terminated by Seller, on the one
hand, or Buyer, on the other hand, upon written notice to the other Party,
in accordance with the provisions of Section 6.7(b), provided that the
Party seeking to so terminate shall have complied with its obligations
under Section 6.7.

      9.2 Effect of Termination. Upon termination of this Agreement prior
to the Closing pursuant to Section 9.1, this Agreement shall be null and
void and of no further force or effect (except that the provisions set
forth in Section 6.2, this Section 9.2 and Article X, and the
Confidentiality Agreement, shall remain in full force and effect in
accordance with their respective terms); and no Party shall have any
further Liability under this Agreement (other than for any wilful breach of
its obligations hereunder).
