                      [FORM OF OPINION OF BUYER'S COUNSEL]

Duquesne Light Company
One Oxford Center

Pittsburgh, PA  15279

Gentlemen:

          This opinion is furnished to you pursuant to Section 8.5 of the Fort
Martin Power Station Asset Purchase Agreement dated as of November 28, 1995, by
and among Duquesne Light Company, a Pennsylvania corporation and AYP Capital,
Inc., a Delaware corporation (the "Agreement").  Unless otherwise defined
herein, capitalized terms used herein and defined in the Agreement shall have
the same meanings herein as therein.

          We have acted as counsel to Buyer in connection with the preparation,
execution and delivery of the Agreement and the purchase by Buyer of the
Purchased Assets as provided for therein.  In connection with this opinion, we
have participated in the preparation or examined executed counterparts or
copies, certified or otherwise identified to our satisfaction, of the Agreement
and such other instruments, agreements, certificates and documents, and made
such further investigation and examination as we have deemed necessary as a
basis for this opinion.  In such examination, we have assumed the genuineness of
all signatures (other than those of the Buyer), the authenticity of all
documents submitted to us as originals and the conformity

to the original documents of all documents submitted to us as copies.  As to any
facts material to our opinion, we have, when relevant facts were not
independently established by us, relied upon the aforesaid instruments,
agreements, certificates and documents.  In addition, we have assumed the due
execution and delivery, pursuant to due authorization, by Seller of the
Agreement.  We are members of the Bar of the State of Pennsylvania and do not
purport to be experts in the laws of any jurisdiction other than the laws of the
State of Pennsylvania and of the United States, and the Delaware General
Corporation Law.

          Based upon and subject to the foregoing, we are of the opinion that:

          1.  Buyer was duly organized and is validly existing as a corporation
and is in good standing under the laws of the State of Delaware and has full
corporate power and authority to execute and deliver the Agreement and
consummate the transactions contemplated thereby.

          2.  The execution, delivery and performance of the Agreement, and the
consummation of the transactions contemplated thereby, have been duly authorized
by the Board of Directors of Buyer and all other corporate action on the part of
Buyer necessary in connection with such execution, delivery and performance has
been duly and validly taken.  The Agreement has been duly executed and delivered
on behalf of Buyer and

constitutes a valid and binding obligation of Buyer, enforceable against Buyer
in accordance with its terms, subject, as to enforcement, to the effect or
application of bankruptcy, insolvency, reorganization and other similar laws of
general applicability relating to or affecting creditors' rights generally,
general equitable principles, whether considered in a proceeding at law or in
equity, and public policies.

          3.  Neither the execution and delivery of the Agreement nor the
consummation of the transactions contemplated thereby violates any provision of
the certificate of incorporation or by-laws of Buyer or any law, regulation or
rule or, to the best of our knowledge after due inquiry, any judgment, decree,
order, permit or license of any federal, Pennsylvania or other state or local
court or governmental agency or body to which Buyer or any of its properties or
assets is bound or subject.

          4.  Except for the orders, consents or approvals set forth in Section
6.3(a) of the Disclosure Schedule to the Agreement [(as amended and revised)]
required to authorize the purchase of the Purchased Assets pursuant to the terms
of the Agreement, which orders, consents or approvals have been obtained and are
in full force and effect, no consent, approval, order or authorization of, or
registration, declaration or filing with, any Federal or Pennsylvania or West
Virginia state governmental authority or regulatory body is required on the part
of Buyer in

connection with the execution and delivery of the Agreement or the acquisition
of the Purchased Assets as contemplated thereby.

          5.  At your request, we hereby confirm that we are not acting as
counsel for Buyer in any pending litigation in which Buyer is a party, and we
have not had referred to us by Buyer for legal advice or legal representation
any matter that we believe might be deemed to be overtly threatened litigation
in which Buyer might become a party.  The statement set forth in the previous
sentence is limited to those matters that Buyer has referred to us for legal
representation or about which any such Person has consulted us as counsel and
with respect to which we have given substantive attention subsequent to
_______________ but prior to _______________.  We have identified those matters
by making inquiry of lawyers currently in our firm who, according to our
records, have been engaged in legal services on behalf of Buyer during that
period, and by examining certain current records that we maintain for our
internal operations.  In that process we have not undertaken any independent
review of documents or records concerning such Persons that are in our
possession.

          We are furnishing this opinion for you in connection with the closing
of the transaction occurring today.  The opinion is solely for your benefit and
is not to be used, circulated,

Gentlemen:

          I have acted as counsel to AYP Capital, Inc., an affiliate of
Allegheny Power Service Corporation ("APSC"), in connection with that certain
Fort Martin Power Station Asset Purchase Agreement dated as of November 28 1995,
by and among Duquesne Light Company, a Pennsylvania corporation and AYP Capital,
Inc., a Delaware corporation (the "Agreement").  Unless otherwise defined
herein, capitalized terms used herein and defined in the Agreement shall have
the same meanings herein as therein.

          I am a member of the Bar of the State of Pennsylvania.

          At your request, I have inquired of lawyers employed by APSC and its
affiliates responsible for administering claims and litigation against APSC and
its affiliates, including Buyer, and of certain officers of Buyer, and on the
basis of such inquiry am pleased to confirm that there is not pending or, to my
knowledge, threatened any claim, action, suit, proceeding, arbitration,
investigation, hearing or notice of hearing which seeks to make illegal, enjoin
or prevent the transactions contemplated by the Agreement.

                                    Very truly yours,

                     [FORM OF OPINION OF SELLER'S COUNSEL]
                            [Dated the Closing Date]

_____________________


Gentlemen:
          This opinion is furnished to you pursuant to Section

9.5  of the Fort Martin Power Station Asset Purchase Agreement, dated as of
November 28, 1995, by and among Duquesne Light Company, a Pennsylvania
corporation, and AYP Capital, Inc., a Delaware corporation (the "Agreement").
The capitalized terms used herein and not defined herein shall have the
respective meanings set forth in the Agreement.

          I have acted as counsel to Seller in connection with the preparation,
execution and delivery of the Agreement and the sale of the Purchased Assets by
Seller to AYP Capital, Inc. pursuant to the Agreement.  As such counsel, I have
examined originals (or copies certified or otherwise identified to my
satisfaction) of the Agreement, the deed referred to in Section 4.2 of the
Agreement (the "Deed"), the bill[s] of sale referred to in Section 4.2 of the
Agreement (the "Bill[s] of Sale") and such other instruments, certified and 
documents and have reviewed such questions of law as I have deemed necessary or
<PAGE>
 
------------------------
                  , 1996
------------------
Page 2

appropriate for the purpose of this opinion. In such examination, I have assumed
the genuineness of all signatures (other than those of the Seller), the
authenticity of all documents submitted to me as originals and the conformity to
the original documents of all documents submitted to me as copies. As to any
facts material to this opinion, I have, when relevant facts were not
independently established, relied upon the aforesaid instruments, certificates
and documents. In addition, I have assumed the due execution and delivery
pursuant to due authorization by Buyer of the Agreement.

          Based upon the foregoing, I am of the opinion that:

          1.   Seller was duly organized and is validly existing as a
corporation and is in good standing under the laws of the Commonwealth of
Pennsylvania and the State of West Virginia and has full corporate power and
authority to execute and deliver the Agreement, the Deed, the Bill[s] of Sale
[and other instruments] and consummate the transactions contemplated thereby.

          2.   The execution, delivery and performance of the Agreement, the
Deed, the Bill[s] of Sale [and other instruments], and the consummation of the
transactions contemplated thereby, have been duly authorized by the Board of
Directors of Seller and all other corporate action on the part of Seller
necessary in connection with such execution, delivery and performance has been 
duly and validly taken.  The Agreement, the Deed and the Bill[s]

of Sale have each been duly executed and delivered on behalf of Seller and
constitute valid and binding obligations of Seller, enforceable against Seller
in accordance with their respective terms except as enforcement may be limited
by bankruptcy, insolvency, reorganization and other similar laws of general
applicability relating to or affecting creditors' rights generally and general
equitable principles, whether considered in a proceeding at law or in equity.

          3.   Neither the execution and delivery of the Agreement nor the
consummation of the transactions contemplated thereby violates any provision of
the Articles of Incorporation or By-Laws of Seller or any statute, law,
regulation or rule, or, to the best of our knowledge after due inquiry, any
judgment, decree, order, permit or license, of any Federal or Pennsylvania
or West Virginia state court or governmental agency or body to which Seller is 
subject or by which any of its properties or assets, including, without 
limitation, Unit No. 1, is bound or subject.

          4.   To the best of my knowledge after due inquiry, Seller is not in
violation of any statute, law, judgment, decree, order, permit, license,
regulation or rule of any Federal or Pennsylvania or West Virginia state court
or governmental agency or body relating to or affecting the ownership, use or
operation of Unit No. 1, other than such violations as would not,

adversely affect or interfere with the ownership, use or operation of Unit No. l
or adversely affect the ability of Seller to execute and deliver the Agreement,
the Deed, the Bill[s] of Sale [and other instruments] and consummate the
transactions contemplated thereby.

          5.   Except for orders of the [PaPUC and the FERC] authorizing the
sale of the Purchased Assets pursuant to the terms of the Agreement, which
orders have been obtained and are in full force and effect, no consent,
approval, order or authorization of, or registration declaration or filing with,
any Federal or Pennsylvania or West Virginia state governmental authority or
regulatory body is required on the part of Seller in connection with the 
execution and delivery of the Agreement, the Deed, the Bill[s] of Sale [or 
other instruments] or the sale of the Purchased Assets to Buyer as 
contemplated thereby.

          6.   There is no claim, action, suit, proceeding, arbitration,
investigation or hearing or notice of hearing pending or, to the best of our
knowledge after due inquiry, threatened, before any court or governmental or
administrative authority which seeks to make illegal, enjoin or prevent the
transactions contemplated by this Authority.

          7.  The Deed and the Bill[s] of Sale [and other instruments] are in
form sufficient to transfer to the Buyer all

of the Seller's right, title and interest to the Purchased Assets; provided,
however, that no opinion is expressed with respect to the existence, nature or
extent of the Seller's right, title and interest in the Purchased Assets.

          I am a member of the Bar of the Commonwealth of Pennsylvania and I do
not express any opinion as to any law other than the laws of the Commonwealth of
Pennsylvania and the Federal law of the United States of America.  With respect
to matters governed by the laws of the State of West Virginia, I have, with your
consent relied entirely upon the opinion of _______________, without independent
investigation.

          I am furnishing this opinion for you in connection with the closing of
the transaction occurring today.  The opinion is solely for your benefit and is
not to be used, circulated, quoted or otherwise referred to for any other
purpose without my written permission.

Section 5.4(a)--Violations of Articles, By-Laws or Contracts.
 
     1.   None, except as set forth in response to 5.4(b).
 
Section 5.4(b)--Consents; Compliance with Applicable Laws.
 
     1.   Required Consents and Approvals
 
          (i)  Approval, if required, under Section 1102(a)(3) of the
               Pennsylvania Public Utility Code [66 Pa. C.S.A. (S) 1102(a)(3)]
 
          (ii) Approval, if required, under (S) 521(a) of the Pennsylvania
               Public Utility Code  [66 Pa. C.S.A. (S) 521(a)]

                                     DS-4
<PAGE>
 
         (iii) Approval, if required, under Section 203 of the Federal Power
               Act (16 U.S.C. (S) 824b) for the sale by Duquesne of a part
               interest in the Fort Martin Station transmission facilities.
 
          (iv) Approval, if required, from West Virginia for Seller to transfer
               to Buyer its Certificate of Public Convenience and Necessity with
               respect to Unit No. 1.
 
     2.   Fort Martin No. 1 Unit meets applicable standards as to particulates
          and opacity with high-efficiency electrostatic precipitators and
          cleaned coal.  From time to time, excursions of opacity normal to
          fossil fuel operations are experienced.  The West Virginia Division of
          Environmental Protection (WVDEP), Office of Air Quality (OAQ) issued
          Notices of Violation (NOVs) for opacity exceedances for the fourth
          quarter of 1993 and the first quarter of 1994 for Fort Martin.  In
          addition, Fort Martin has reported opacity exceedances for each
          quarter thereafter.

          Because of the stringent 10% opacity limit in West Virginia which led
          to the above-mentioned NOV's, Monongahela and other West Virginia
          electric utilities petitioned the OAQ in 1994 to revise the opacity
          limit from 10% to 20% in order to be consistent with

                                     DS-5
<PAGE>
 
          surrounding states and the federal New Source Performance Standards
          (NSPS).  The OAQ on October 21, 1994 published a proposed revision to
          Title 45, Regulation 2 to increase the opacity limit to 20%.  The
          final rule was submitted to the state legislature in West Virginia for
          approval in early 1995.  The proposed increase in the opacity limit
          was rejected and the opacity limit remains at 10%.  The plant
          continues to have occasional opacity exceedances and there are
          presently two (2) outstanding NOVs.  Refurbishment of the
          electrostatic precipitators is scheduled to be completed during a
          planned major outage in 1996.  The refurbishment may mitigate these
          occasional opacity exceedances.
 
     3.   Under the National Pollutant Discharge Elimination System (NPDES), a
          permit for the Fort Martin ash disposal site is in place.  However,
          the NPDES permit renewal for this disposal site contains what the
          Operating Subsidiaries of Allegheny Power System (APS) believe are
          overly stringent discharge limitations.  The WVDEP has temporarily
          stayed the stringent permit limitations while the Operating
          Subsidiaries continue to work with WVDEP and EPA in order to
          scientifically justify less stringent limits.  Where this is not
          possible, installation of waste water treatment

                                     DS-6
<PAGE>
 
          facilities may become necessary.  The cost of such facilities, if
          required, cannot be predicted by Duquesne or APS at this time.
 
     4.   Pursuant to the National Groundwater Protection Strategy, West
          Virginia adopted a Groundwater Protection Act in 1991.  This law
          establishes a statewide antidegradation policy which could require
          reconstruction of existing landfills and surface impoundments as well
          as groundwater remediation at Fort Martin.  Groundwater protection
          standards were approved and implemented in 1993 (based on EPA drinking
          water criteria) which established compliance limits.  Pursuant to the
          groundwater protection standards variance provision, on October 26,
          1994 the APS Operating Subsidiaries jointly filed with American
          Electric Power and Virginia Power, a Notice of Intent (NOI) to request
          class or source variances from the groundwater standards for steam
          electric operating facilities in West Virginia.  Additionally, each of
          the companies filed individual NOI's.  Technical and socio-economic
          justification to support the variance requests are being developed and
          the costs shared by the Operating Subsidiaries under a contract with
          EPRI.  While the justification for the variance requests is being
          developed, Fort Martin is protected from any

                                     DS-7
<PAGE>
 
          enforcement action.  Because variance requests must ultimately be
          approved by the West Virginia legislature, Duquesne or APS cannot
          predict the outcome.
 
     5.   Under Title IV of the CAAA, Fort Martin No. 1 Unit is classified as a
          Phase I Group 1 boiler (tangential fired).  It is anticipated that no
          plant modifications will be required to meet NOx requirements for
          Phase I.  For Phase II, the compliance strategy may require the
          installation of Low NOx Burners.
 
     6.   Currently, Fort Martin No. 1 Unit is not impacted by Title I of the
          CAAA.
 
Section 5.4(c)--Environmental.
 
          None.
 
Section 5.4(d)--Permits.
 
     1.   The permits listed in Attachment I to this Disclosure Statement.
 
     2.   Additional permits and/or approvals as set forth in response to

     3.   The current ash disposal site is estimated to have capacity to receive
          ash resulting from coal combustion at Fort Martin for seven (7) years.
          Engineering, permitting and construction of a new site to meet current
          regulatory criteria must be completed prior to exhausting the capacity
          of the current disposal site.

     1.   Richard Armstrong and Linda Armstrong, et al. v. the Duquesne Light
          Company, et al. No. 93-C-54 (West Virginia).
 
     2.   Seller is one of the plaintiffs challenging the regulation promulgated
          by West Virginia to establish the method used for calculating the
          kilowatt hour tax which was in effect between August 11, 1989 and June
          1, 1995.  The plaintiffs filed a declaratory judgment action in the
          Circuit Court of Kanawa County, West Virginia on March 29, 1990,
          seeking a ruling that the regulations adopted by the State Tax
          Commissioner to implement a tax upon the generation of electric power,
          exceeded the Commissioner's statutory authority and was
          unconstitutional.  In calculating the tax imposed upon generators
          under the statute, which was based upon the number of kilowatt hours
          of electricity produced, the plaintiffs contended that the statutory
          phrase "net generation available for sale" entitled them to deduct
          electric power generated in West Virginia and consumed in the utility
          business as well as electricity lost in the process of transmission
          and distribution before

                                     DS-9
<PAGE>
 
          calculating the tax.  The Commissioner contended that only electricity
          consumed in the process of generation was deductible and that all
          other generation was taxable, thereby increasing the taxes payable.
          The plaintiffs paid the tax in accordance with the State's position
          and filed claims for refunds.  The Circuit Court of Kanawha County
          ruled in favor of the position of the Commissioner and the plaintiffs
          have appealed to the West Virginia Supreme Court of Appeals, where the
          case is currently pending.  If the Supreme Court of Appeals rules in
          favor of the plaintiffs, the decision would likely be used as a
          precedent in pursuing tax refund claims.

Section 5.8--Insurance.
 
     1.   The policies currently in effect are listed in Attachment III to this
          Disclosure Statement.
 
     2.   Currently, there is one coverage dispute pending which is related to
          caustic induction incident that occurred January 1995.  Buyer will not
          be obligated in any way by the outcome of this dispute.
