FirstEnergy Corp.

Akron, Ohio 44308

Dear Sirs:

          This letter confirms the agreement in principle of 
Duquesne Light Company ("DLC"), a Pennsylvania corporation, and 
FirstEnergy Corp. ("FE"), an Ohio corporation, acting on behalf 
of Ohio Edison Company, Pennsylvania Power Company, The Cleveland 
Electric Illuminating Company, and The Toledo Electric Company 
(together, "FE Subsidiaries"), regarding the exchange of 
interests in certain electric generation facilities (hereinafter 
"Generation Exchange").  FE shall cause the FE Subsidiaries to 
perform all acts described herein as necessary or appropriate to 
fulfill FE's obligations hereunder.  The terms of the agreement 
in principle are as follows:

          1.  Interests Exchanged.  The Parties intend to 
exchange the following interests in electric generation assets:
  
             (a)  DLC will assign, convey, transfer and deliver 
to the FE Subsidiaries its rights, title and interest in and to 
the following electric generation plants: Beaver Valley Power 
Station Units Nos. 1 & 2 (subject to Section 3 hereof), Perry 
Unit No. 1, W.H. Sammis Unit No. 7, Bruce Mansfield Units Nos. 1, 
2 & 3, and Eastlake Unit No. 5 (together, "DLC Interests"), as 
described and identified in Exhibit 1 hereof.

             (b)  The FE Subsidiaries will assign, convey, 
transfer and deliver to DLC its rights, title and interest in and 
to the following electric generation plants:  all units located 
at the Avon Lake, New Castle, and Niles generating stations 
(together, "FE Interests"), as described and identified in 
Exhibit 2 hereof.

             (c)  Each Party will be responsible for the costs of 
any state or local transfer taxes associated with the transfer of 
its real property to the other.

          2.  Structure of Exchange.

             (a)  The Generation Exchange will be structured to 
qualify as a tax deferred, like-kind exchange under Internal 
Revenue Code Section 1031.  The Parties recognize, however, that 
certain assets associated with the exchange may constitute 
nonqualifying property under Section 1031.  

                              - 7 -



             (b)  The Generation Exchange would be followed 
immediately by DLC's sale of the FE Interests to the winning 
bidder ("Winning Bidder") in DLC's generation auction ("DLC 
Auction"), except as provided in Section 7. 

             (c)  FE will indemnify and hold DLC harmless against 
claims and liabilities associated with its temporary ownership of 
the FE Interests to the extent such claims and liabilities are 
not assumed by the Winning Bidder.

          3.  Beaver Valley Unit 2.  DLC will terminate the 
Facility Leases  and will be responsible for all payments and 
expenses associated with such termination.  DLC will indemnify 
and hold FE harmless against any claims and liabilities 
associated with the termination of the Facility Leases.

          4.  FE Financial Commitment.  FE will provide a 
financial commitment that DLC has determined will ensure that the 
net proceeds from the DLC Auction will be sufficient, at a 
minimum, to maintain or reduce the level of stranded cost 
recovery approved by the PaPUC in its May 29, 1998 restructuring 
order. 

          5.  Decommissioning.  DLC will be responsible for its 
share of nuclear decommissioning costs for the Beaver Valley 
Power Station and Perry Unit 1.  The Parties will cooperate in 
developing alternative methods for handling DLC's decommissioning 
obligations in a manner that caps such obligations at the total 
funding amounts allowed by the PaPUC in the DLC restructuring 
order and provides FE the after-tax treatment associated with 
those funds that are assumed in such order.  Any additional 
decommissioning costs, or costs associated with spent nuclear 
fuel or the disposal or decommissioning of any other nuclear 
equipment, facilities or properties of any kind, will be the sole 
responsibility of FE.

          6.  Labor.  The Parties will cooperate to resolve 
labor-related matters, including with respect to union contracts, 
workforce levels, severance, and employee benefits, in a manner 
that treats employees fairly and equitably apportions any related 
costs between the Parties.  The definitive agreements for the 
Generation Exchange shall clearly define and apportion the rights 
and obligations of the Parties regarding these matters.

          7.  FENOC.

             (a)  DLC will assign, convey, transfer and deliver 
its right, title and interest in the Beaver Valley Power Station 
to FE, including the transfer of responsibility for the operation 
and maintenance of the plant to FirstEnergy Nuclear Operating 
Company ("FENOC"), and DLC's interest in Perry Unit 1 ("Nuclear 
Interest Transfer"), as soon as practicable after the receipt of 
all associated regulatory approvals and the satisfaction of any 
other condition, as set forth in the definitive agreements, to 
such a transfer, including conditions related to the Facility 
Lease, decommissioning, labor-related matters, nuclear fuel, and 
transmission as further described Sections 3, 5, 6, 9, and 10 
hereof.  Such transfers of DLC's right, title and interest and 
operating responsibility in or for its nuclear interests will be 
made as the conditions precedent for such transfer of Beaver 
Valley Unit 1, Beaver Valley Unit 2 and/or Perry Unit 1 are 
satisfied.
             (b)  Upon execution of this agreement in principle, 
DLC shall provide written notification to FE that it supports the 
pending Nuclear Regulatory Commission application by FENOC to 

                              - 8 -



assume operating responsibility for Perry Unit 1.  DLC's support 
for such NRC application shall not constitute a waiver of DLC's 
right to withhold consent to the assignment of such operating 
responsibility to FENOC pursuant to the Perry Unit 1 Operating 
Agreement, dated as of March 10, 1987, such consent to be 
required and provided upon execution of the Exchange Agreements 
described in Section 14.

          8.  Cooperation in DLC Auction.  

             (a)  FE will cooperate with DLC in a commercially 
reasonable manner to provide for the timely and successful 
completion of the DLC Auction, including providing the due 
diligence specified in Section 15 and designating a person or 
persons having engineering and operational familiarity with 
respect to each of the FE Interests to be the principal contact 
person(s) for the auction of the FE Interests and causing such 
person(s) to make sufficient time available for such purpose as 
reasonably required by DLC or its consultants or advisors.

             (b)  FE agrees that it will not submit a bid in 
DLC's auction.  

             (c)  For any FE employee(s) affected by the 
Generation Exchange to whom FE desires to submit an offer of 
continuing employment, FE shall disclose the identity of such 
employee(s) to DLC reasonably in advance of the date when bids 
are due in the DLC Auction.

             (d)  Nothing in this agreement in principle or the 
definitive agreements shall be deemed to grant FE any rights with 
respect to, or otherwise to participate in, the implementation of 
the DLC Auction.

          9.  Fuel.  Each Party will sell, assign, convey, 
transfer and deliver  to the other its rights, title and interest 
in and to the fuel inventories, including nuclear fuel in core, 
associated with the generation interests being exchanged at the 
cost of such fuel inventories.  Each Party will also assign, to 
the extent assignable, all rights and obligations under fuel 
contracts applicable to such interests.  To the extent any such 
contract is not assignable, including leases for nuclear fuel, 
the Party to such contract shall agree to resell the fuel 
delivered under such contract or lease to the other Party and 
receive from the other Party the cost of such deliveries on an 
as-incurred basis during the term of the contract or lease, 
provided that no such contract shall be extended, nor shall any 
additional nuclear fuel be added to any such leases.

         10.  Transmission Facilities.  DLC will sell, assign, 
convey, transfer and deliver to FE (i) the transmission 
facilities necessary and appropriate to permit the delivery of 
power from the Beaver Valley Power Station and the Bruce 
Mansfield Power Station to the FE transmission system, and (ii) 
any substation and related facilities as are necessary to meet 
Nuclear Regulatory Commission requirements for the safe and 
reliable operation of the Beaver Valley Power Station, provided 
that arrangements are made for continued use by DLC of such 
substation facilities as are necessary for the integration and 
operation of its system.  The purchase price for the DLC 
facilities so transferred shall be equal to the net book costs of 
such facilities at the closing date of such transaction.

         11.  CAPCO Agreements.  All contractual arrangements 
associated with the Central Area Power Coordination Group 
("CAPCO"), including the unit operating agreements associated 
with the DLC Interests, the Transmission Facilities Agreement, 
and the CAPCO Basic Operating Agreement, will be modified or 
terminated so that DLC shall have no further rights or 

                              - 9 -



obligations respecting such agreements and in a manner necessary 
or appropriate to permit compliance by FE with any law, 
regulation or contract.

         12.  Property Tax Litigation.  As of the date of 
execution of this agreement in principle, FE will receive the 
full benefits, including any refunds, and shall bear the full 
costs after such date related to, pending litigation and appeals 
regarding the property taxes for the Perry, Eastlake and Sammis 
plants, provided, however, that if the Generation Exchange as to 
any such unit is not consummated for any reason, the Parties 
shall negotiate arrangements that place them in the same position 
as to such unit, with respect to any such costs or benefits, as 
if this agreement in principle had not been executed.  DLC will 
continue to take all actions necessary in such proceedings, in 
cooperation with FE, until the closing subject to reimbursement 
of all expenses upon closing.

         13.  Litigation.  The Generation Exchange will 
constitute a full settlement of all existing and future 
litigation between the Parties related to their ownership 
interests in the CAPCO assets.  Following the execution of this 
agreement in principle, definitive settlement agreements as to 
any pending litigation will be negotiated consistent with this 
agreement in principle and will take effect on the date of 
closing of the Generation Exchange.  In addition, upon execution 
of this agreement in principle, the Parties will jointly seek an 
order of the Court in the current litigation regarding Eastlake 
Unit 5 (the "Eastlake Litigation") to stay all proceedings in the 
Eastlake Litigation pending the complete execution of Exchange 
Agreements.  Upon the complete execution of the Exchange 
Agreements, the Parties will jointly present to the Court an 
agreed order which will have the effect of suspending the 
Eastlake Litigation while preserving the Parties' rights to 
continue the Eastlake Litigation in the event that the Generation 
Exchange does not close.  If the Generation Exchange does not so 
close, DLC shall retain all rights with respects to such 
litigation, with the exception being that execution of the 
Exchange Agreements shall constitute an irrevocable waiver by DLC 
of claims for money damages in the Eastlake Litigation but not 
for any other remedy, including the partition or sale of the 
unit.

         14.  Definitive Agreements.  Following the execution of 
this agreement in principle, the Parties shall in good faith 
negotiate as soon as practicable definitive agreements (together 
with any related schedules, together the "Exchange Agreements") 
reflecting the terms of the Generation Exchange as set forth in 
this agreement in principle and containing such additional terms, 
covenants, representations and warranties, assumptions of 
liability and other conditions as are normal and customary for 
transactions of this kind.  The representations, warranties, 
covenants and conditions for FE and DLC are expected to include, 
but not necessarily be limited to, those set forth in the Asset 
Purchase Agreement Term Sheet, attached as Appendix D to the DLC 
Generation Auction Plan.

          It is specifically agreed and understood by the Parties 
that the terms set forth in this agreement in principle do not 
constitute all of the major terms which will be included in the 
Exchange Agreements, that the terms set forth herein are subject 
to further discussion, negotiation, and due diligence, and that 
this agreement in principle is an expression of intent only and 
is not intended, nor will it be alleged by either Party, to 
create or result in any legally binding obligation upon the 
Parties, with the sole exception being this sentence and Sections 
7(b) and 23.

         15.  Due Diligence. 

             (a)  Between the date of this letter and the date of 
consummation of the Generation Exchange, FE will (i) give DLC and 
its authorized representatives (including without limitation, its 
professional and financial advisors and any qualified bidder in 
the DLC Auction, together "DLC Representatives"), access during 
regular business hours upon reasonable notice to all of the 
generating plants constituting the FE Interests and to all of its 
books and records associated with the FE Interests, (ii) permit 
DLC Representatives to make such reasonable inspections as it may 
require, including the performance of Phase I and Phase II 
environmental audits as to the FE Interests, provided that DLC 
bears all of the expenses related to such audits and inspections,

furnish DLC Representatives with such financial and operating 
data and other information with respect to the FE Interests as 
DLC Representatives may request from time to time, and (iv) keep 
DLC Representatives apprised of material developments in the 
operation and maintenance of the FE Interests.  As provided in 
the letter agreement between FE and DLC respecting confidenti-
ality, the information provided to DLC Representatives will be

bidder in the DLC Auction to execute a confidentiality agreement 
providing similar protections for due diligence information 
provided by FE to such bidders.

consummation of the transactions contemplated herein or 
termination hereof, DLC will keep FE apprised of material 
developments regarding the operation and maintenance of the 
Beaver Valley Power Station and shall otherwise provide FE access 
to such information respecting Beaver Valley as is reasonably 
required for FE to perform due diligence for the Generation 
Exchange.  To the extent DLC determines that certain due 
diligence information should be provided to FE only pursuant to a 
confidentiality agreement, the Parties shall negotiate such an 
agreement in good faith.

         16.  Assumption of Liabilities.  DLC shall cause the 
Winning Bidder to assume such liabilities, whether known or 
unknown, absolute or contingent, direct or indirect, relating to 
the FE Interests as are normal and customary in transactions of 
this kind, including liabilities relating to DLC's temporary 
ownership of the FE Interests.  FE will assume such liabilities, 
whether known or unknown, absolute or contingent, direct or 
indirect, relating to the DLC Interests as are normal and 
customary in transactions of this kind.  Each Party shall 
indemnify the other against any claim, and any reasonable 
expenses incurred by the other party as to such claim, asserting 
that the other Party's execution of this agreement in principle 
or the Exchange Agreements constitutes an interference with any 
contractual obligation of the first Party.

         17.  Representations and Warranties.  FE will provide 
representations and warranties to DLC that are normal and 
customary for transactions of this kind and the Winning Bidder 
shall be an intended third party beneficiary thereof.  DLC will 
provide representations and warranties to FE with respect to the 
DLC Interests that are normal and customary for transactions of 
this kind, provided that recognition shall be given for the fact 
FE, not DLC, is the operator of certain of the DLC Interests.

         18.  Covenants.  Each Party will provide such covenants 
as are normal and customary for transactions of this kind, 

                              - 11 -



including, without limitation, covenants to operate and maintain 
their respective generation interests in the regular and ordinary 
course from the date of execution of the Exchange Agreements to 
the closing date of the Generation Exchange.

         19.  Conditions.  The Exchange Agreements shall include 
conditions to closing the transaction(s) as are normal and 
customary for transaction of this kind, including conditions 
related to securing necessary regulatory approvals and for the 
absence of any material breach of covenants, representations or 
warranties under the Exchange Agreements and, furthermore, a 
condition that the Agreement and Plan of Merger between DQE, Inc. 
and Allegheny Energy, Inc. has been terminated and there is no 
court order requiring DQE to consummate the transactions 
contemplated under said agreement.

         20.  Interim Operations; Proration of Expenses. The 
Exchange Agreements shall include covenants regarding interim 
operation of the FE Interests and DLC Interests following 
execution of such agreements and prior to closing of the 
Generation Exchange as are normal and customary for transactions 
of this kind, including the use of prudent utility practice in 
operating and maintaining such interests, a fair apportionment of 
the risk of loss or damage to such interests prior to closing, 
and limitations on encumbering such interests or making certain 
capital expenditures during such period.  The Exchange Agreements 
also shall include provisions regarding the proration of costs 
and expenses as of the closing date, including as to property 
taxes, fuel inventories, etc.

         21.  Expenses.  Except as otherwise provided for herein, 
each Party will bear its own expenses associated with the 
Generation Exchange, including expenses associated with legal, 
financial or other advisors retained to negotiate the Exchange 
Agreements.  

         22.   Termination.  If the Parties do not execute 
definitive Exchange Agreements by December 21, 1998, this 
agreement in principle shall be terminable by either Party upon 
written notice to the other.  Following any such termination, 
neither Party will have any further liability or obligation to 
the other regarding an exchange of generation assets. 

         23.   Public Announcements; Confidentiality.

             (a)  The parties agree that this agreement in 
principle shall be a public document and, as such, may be 
disclosed to employees, shareholders and regulatory bodies as 
necessary and appropriate.  Neither Party, however, shall, 
without the prior consent of the other, make public statements 
regarding ongoing negotiations to reach agreement with respect to 
the Exchange Agreements. 

             (b)   FE acknowledges and agrees that DLC will 
submit this agreement in principle to the PaPUC for the purpose 
of obtaining PaPUC approval of the Generation Exchange, including 
authorization for the accounting for the net proceeds from the 
sale of the FE Interests.  It is anticipated that the PaPUC will 
be in a position to issue an order regarding this Generation 
Exchange not later than December 21, 1998.

         24.  Governing Law.  This agreement in principle shall 
be governed by and construed in accordance with the laws of the 
Commonwealth of Pennsylvania without giving effect to the 
provisions thereof relating to conflicts of law.

                              - 12 -



         25.  Counterparts.  This agreement in principle may be 
executed in two or more counterparts, each of which shall be 
deemed to be an original but all of which shall constitute one 
and the same agreement.

          If the foregoing correctly reflects the understanding 
between us, please so indicate by signing and returning the 
enclosed copy of this letter at your earliest convenience.
