           Guaranteed to the extent Duquesne Capital has funds as set forth
                                      herein by

                               Duquesne Light Company 

                                  ------------------

             The % Cumulative Monthly Income Preferred Securities, Series A
          (the "Series A MIPS") offered hereby are being issued by, and
          represent limited partner interests in, Duquesne Capital L.P., a
          Delaware special purpose limited partnership ("Duquesne
          Capital").  Duquesne Capital was formed for the sole purpose of
          issuing its limited partnership interests and lending the
          proceeds thereof to Duquesne Light Company ("Duquesne Light"),
          the sole General Partner of Duquesne Capital.   The proceeds of
          the Series A MIPS will be loaned to Duquesne Light in return for
          __% Subordinated Deferrable Interest Debentures, Series A (the
          "Series A Debentures").  
             Holders of the Series A MIPS will be entitled to receive, 
          to the extent of funds held by Duquesne Capital and legally 
          available therefor, periodic cash distributions ("dividends"), at 
          an annual rate of % of the liquidation preference of $25 per 
          security, accumulating from the date of original issuance and 
          payable monthly in arrears on the last day of each calendar month, 
          commencing May 31, 1996.  The payment of dividends and payments on 
          liquidation or redemption with respect to the Series A MIPS, to 
          the extent of funds held by Duquesne Capital and legally available 
          therefor, will be guaranteed under a Payment and Guarantee Agreement 
          (the "Guarantee") of Duquesne Light to the extent described herein 
          and in the accompanying Prospectus.  The Guarantee does not cover
          payment of amounts in respect of the Series A MIPS to the extent
          that Duquesne Capital does not have legally available funds for
          the payment thereof and cash on hand sufficient to make such
          payment.  Duquesne Capital's earnings will be limited to payments
          by Duquesne Light on the Series A Debentures and any other
          Indenture Securities (as defined in the accompanying Prospectus). 
          If Duquesne Light fails to make interest payments on the Series A
          Debentures, Duquesne Capital will have insufficient funds to pay
          dividends on the Series A MIPS and the Guarantee will not cover
          payment of such dividends.  In such event, the holders of Series
          A MIPS may enforce certain rights in respect of the Series A
          Debentures.  See "Description of the Guarantee" in the
          accompanying Prospectus.

     (2)   Duquesne Capital and Duquesne Light have agreed to
           indemnify the several Underwriters against certain
           liabilities, including liabilities under the Securities
           Act of 1933, as amended.  See "Underwriting".

     (3)   In view of the fact that the proceeds of the sale of the
           Series A MIPS will be loaned to Duquesne Light, Duquesne
           Light has agreed, in the Underwriting Agreement, to pay to
           the Underwriters as compensation for their services $
           per security (or $   in the aggregate); provided that
           such compensation will be $   per security sold to
           certain institutions.  Therefore, to the extent that
           Series A MIPS are sold to such institutions, the actual
           amount of Underwriters' compensation will be less than the
           amount specified in the preceding sentence and the
           Proceeds to Duquesne Capital will be greater than the
           amount set forth in the table above.  See "Underwriting".

     (4)   Expenses of the offering which are payable by Duquesne
           Light are estimated to be $550,000.

          Underwriters, as specified herein, subject to receipt and
          acceptance by them and subject to their right to reject any order
          in whole or in part.  It is expected that delivery of the Series
          A MIPS will be made only in book-entry form through the

          (Cover continued)

             The Guarantee and the Series A Debentures will rank
          subordinate in right of payment to all Senior Indebtedness (as
          defined in the accompanying Prospectus) of Duquesne Light.  As of
          December 31, 1995, Duquesne Light had approximately $1.7 billion
          of Senior Indebtedness outstanding.  

             The Series A MIPS are redeemable, at the option of Duquesne
          Capital (with Duquesne Light's consent), in whole or in part,
          from time to time, on or after May 31, 2001, at $25 per security
          plus accumulated and unpaid dividends to the date fixed for
          redemption (the "Redemption Price").

             In addition, upon redemption or payment at maturity of the
          Series A Debentures, the proceeds from such redemption or payment
          will be applied to redeem Series A MIPS.  Under certain
          circumstances following the occurrence of a Special Event (as
          defined in the accompanying Prospectus), Duquesne Light may cause
          Duquesne Capital to redeem the Series A MIPS in whole at the
          Redemption Price or Duquesne Light may cause Duquesne Capital to
          distribute the Series A Debentures in exchange for the Series A
          MIPS in whole.  If Series A Debentures are distributed, Duquesne
          Light will use its best efforts to have such Series A Debentures
          listed on the same exchange on which the Series A MIPS are then
          listed.  See "Certain Terms of the Series A MIPS--Redemption or
          Exchange" and "Certain Terms of the Series A Debentures".

             In the event of the liquidation of Duquesne Capital, holders
          of Series A MIPS will be entitled to receive for each security a
          liquidation preference of $25 plus accumulated and unpaid
          dividends to the date of payment, subject to certain limitations. 
          See "Description of the MIPS--Liquidation Distribution" in the
          accompanying Prospectus.

             Duquesne Light may defer interest payments on the Series A
          Debentures for up to 60 months and, as a consequence, dividends
          on the Series A MIPS would be deferred during any such interest
          deferral period.  

             The Series A MIPS have been approved for listing on the New
          York Stock Exchange, subject to official notice of issuance.

                          CERTAIN INVESTMENT CONSIDERATIONS

             Prospective purchasers of the Series A MIPS should carefully
          review the information contained in the Prospectus and elsewhere
          in this Prospectus Supplement and should particularly consider
          the following matters.  Capitalized terms used in this Prospectus
          Supplement shall have the meanings ascribed thereto in the
          Prospectus  unless otherwise  defined in this Prospectus
          Supplement.

          SUBORDINATION OF DUQUESNE LIGHT'S OBLIGATIONS

             The payment of dividends and payments on liquidation or
          redemption with respect to the Series A MIPS, to the extent of
          funds held by Duquesne Capital and legally available to make such
          payments, will be guaranteed by Duquesne Light under the
          Guarantee.  The Guarantee does not cover payment of amounts in
          respect of the Series A MIPS to the extent that Duquesne Capital
          does not have legally available funds for the payment thereof and
          cash on hand sufficient to make such payment.

             Duquesne Light's  obligations under the Guarantee and the
          Series A Debentures will be subordinate in right of payment to
          all Senior Indebtedness of Duquesne Light.  As of December 31,
          1995, Duquesne Light had approximately $1.7 billion of Senior
          Indebtedness outstanding (exclusive of certain guarantees and
          other contingent obligations, but inclusive of capitalized lease
          obligations and current installments and short-term notes
          payable).  See "Description of the Guarantee--Status of the
          Guarantee" and "Description of the Debentures and the
          Indenture--Subordination" in the Prospectus.  There are no
          provisions in the Series A MIPS, the Guarantee, the Partnership
          Agreement or the Indenture that limit Duquesne Light's ability to
          incur additional indebtedness, including indebtedness that ranks
          senior to the Guarantee and the Series A Debentures.

          OPTION TO EXTEND INTEREST PAYMENT PERIOD

             Duquesne Light has the right under the Indenture, from time to
          time, to extend interest payment periods on the Series A
          Debentures for up to 60 consecutive months, and, as a
          consequence, monthly dividends on the Series A MIPS will be
          deferred by Duquesne Capital (and will continue to accumulate but
          without interest on any amounts so deferred) during any such
          extended interest payment period.  During any such extended
          interest period, Duquesne Light may not declare or pay dividends
          on, or redeem, purchase, acquire or make a liquidation payment
          with respect to, any shares of its capital stock.  Prior to the
          end of any such extended interest payment period of less than 60
          consecutive months, Duquesne Light may further extend the
          interest payment period; provided that such extended interest
          payment period, together with all such further extensions
          thereof, may not exceed a period of 60 consecutive months. 
          Following the termination of any extended interest payment
          period, if Duquesne Light has paid all amounts then due, Duquesne
          Light shall have the right to again extend interest payment
          periods for up to 60 consecutive months, subject to the above
          requirements.  Duquesne Light has no current intention to extend
          the interest payment period as described above.  See "Description
          of the Debentures and the Indenture--Option to Extend Interest
          Payment Period" and "Description of the MIPS--Voting Rights" in
          the accompanying Prospectus.

          TAX CONSEQUENCES OF EXTENDED INTEREST PAYMENT PERIOD

             Because Duquesne Light has the right to extend the interest
          payment period on the Series A Debentures, the Series A
          Debentures will be treated as issued with original issue discount
          ("OID") for Federal income tax purposes.  Should an
          extended interest payment period occur, Duquesne Capital will
          continue to accrue income for Federal income tax purposes which
          will be allocated but not distributed to record holders of Series
          A MIPS.  As a result, such a holder will include such income in
          gross income for Federal income tax purposes in advance of the
          receipt of cash, and will not receive the cash related to such
          income if such a holder disposes of the Series A MIPS prior to
          the record date for payment of dividends.  The tax basis of the
          Series A MIPS will be increased by the amount of any OID that is
          included in a Series A MIPS holder's income without receipt of
          cash, and will be decreased when and if such cash is subsequently
          received by such Series A MIPS holder from Duquesne Capital.  See
          "United States Income Taxation--Potential Extension of Interest
          Payment Period" in the accompanying Prospectus.

          SPECIAL EVENT REDEMPTION OR EXCHANGE

             Upon the occurrence and continuation of a Special Event (as
          defined in the accompanying Prospectus, which term, as so
          defined, relates to a change in law or regulation or official
          interpretation thereof), Duquesne Light, as general partner of
          Duquesne Capital (the "General Partner"), will elect to either
          (i) cause Duquesne Capital to redeem the Series A MIPS in whole
          (and not in part) or (ii) cause Duquesne Capital to distribute
          the Series A Debentures in exchange for Series A MIPS.  In the
          case of a Special Event which is a Tax Event, the General Partner
          may also elect to cause the Series A MIPS to remain outstanding. 
          See "Certain Terms of the Series A MIPS--Redemption or Exchange"
          herein and "Description of the MIPS--Special  Event Redemption or
          Exchange" in the accompanying Prospectus.

             Such an exchange will generally be treated as a non-taxable
          exchange and will result in each Series A MIPS holder receiving
          an aggregate basis in its Series A Debentures equal to such
          holder's aggregate tax basis in its Series A MIPS.  A Series A
          MIPS holder's holding period in the Series A Debentures received
          in such an exchange will include the period for which the Series
          A MIPS were held by such holder, provided the Series A MIPS were
          held as a capital asset.

             If such an exchange occurs following a determination that, due
          to a change in law, Duquesne Capital is subject to Federal income
          tax with respect to interest received on the Series A Debentures,
          such exchange will generally be taxable to the Series A MIPS
          holder.  Gain or loss will be recognized in an amount measured by
          the difference between the Series A MIPS holder's basis in its
          Series A MIPS and the value of the Series A Debentures received
          in the exchange.  In such case, the holding period of the Series
          A MIPS holder for the Series A Debentures will not include the
          period for which the Series A MIPS were held.

          POSSIBLE TAX LAW CHANGES

             On March 19, 1996, the Revenue Reconciliation Bill of 1996
          (the "Bill"), the revenue portion of President Clinton's budget
          proposal, was released.  The Bill would, among other things,
          generally deny interest deductions for interest on an instrument
          issued by a corporation that has a maximum weighted average
          maturity of more than 40 years.  The Bill would also generally
          treat as equity an instrument issued by a corporation that has a
          maximum term of 20 years and that is not shown as indebtedness on
          the separate balance sheet of the issuer or, where the instrument
          is issued to a related party (other than a corporation), where
          the holder or some other related party issues a related
          instrument that is not shown as indebtedness on the issuer's
          balance sheet.  The above-described provisions were proposed to
          be effective generally for instruments issued on or after
          December 7, 1995.  If either provision were to apply to the
          Series A Debentures, Duquesne Light would be unable to deduct
          interest on the Series A Debentures.  However, on March 29, 1996,
          the Chairmen of the Senate Finance and House Ways and Means
          Committees issued a joint statement to the effect that it was
          their intention that the effective date of the President's
          legislative proposals, if adopted, will be no earlier than the
          date of appropriate Congressional action.  There can be no
          assurance, however, that current or future legislative proposals 
          or final legislation will not affect the ability of Duquesne 
          Light to deduct interest on the Series A Debentures.  Such a 
          change would constitute a Tax Event, which would permit Duquesne
          Light to cause a redemption of the Series A MIPS or a distribution
          of such Series A Debentures in liquidation of Duquesne Capital, 
          as described more fully under "Description of the MIPS--Special 
          Event Redemption or Exchange" in the accompanying Prospectus.
                
                                DUQUESNE LIGHT COMPANY

               Duquesne Light was formed under the laws of Pennsylvania by
          the consolidation and merger in 1912 of three constituent
          companies.  As part of a corporate reorganization, Duquesne Light
          became a wholly-owned subsidiary of DQE, an energy services

                          CERTAIN TERMS OF THE SERIES A MIPS

               THE FOLLOWING SUMMARY OF CERTAIN TERMS OF THE SERIES A MIPS
          SUPPLEMENTS THE DESCRIPTION OF THE MIPS SET FORTH IN THE
          ACCOMPANYING PROSPECTUS UNDER THE HEADING "DESCRIPTION OF THE
          MIPS", TO WHICH DESCRIPTION REFERENCE IS HEREBY MADE.  

          GENERAL

               The Series A MIPS will be issued as the initial series of
          Preferred Securities pursuant to the Partnership Agreement.

          DIVIDENDS

               Dividends on the Series A MIPS will be cumulative from the
          date of issue and will be payable monthly in arrears on the last
          day of each calendar month at an annual rate of ___% of the
          liquidation preference of $25 per security.  The first dividend
          payment date for the Series A MIPS will be May 31, 1996.

               Dividends on the Series A MIPS are required to be paid to
          the extent that, on any scheduled dividend payment date, Duquesne
          Capital has (x) funds legally available for the payment of such
          dividends, as determined by the General Partner, and (y) cash on
          hand sufficient to permit such payment.  Duquesne Capital's
          earnings will be limited to Duquesne Light's payments of interest
          on the Series A Debentures and any other Indenture Securities. 
          See "Description of the Debentures and the Indenture" in the
          accompanying Prospectus.  Duquesne Light has the right under the
          Indenture, from time to time, to extend the interest payment
          periods on the Series A Debentures for up to 60 consecutive
          months, and, as a consequence, monthly dividends on the Series A
          MIPS will be deferred by Duquesne Capital (and will continue to
          accumulate but without interest on any amounts so deferred)
          during any such extended interest payment period.  See
          "Description of the Debentures and the Indenture--Option to Extend
          Interest Payment Period" in the accompanying Prospectus.

               Dividends on the Series A MIPS will be payable to the
          holders thereof as they appear on the books and records of
          Duquesne Capital on the relevant record dates, which will be one
          Business Day prior to the relevant payment dates; provided,
          however, that if the Series A MIPS of any series are not held by
          a securities depositary, the General Partner shall have the right
          to change such record dates.  

          REDEMPTION OR EXCHANGE

               On or after May 31, 2001, Duquesne Capital may, at its
          option and at the direction of Duquesne Light, redeem the Series
          A MIPS in whole or in part upon not less than 30 nor more than 60
          days' notice at a redemption price of $25 per security plus an
          amount equal to accumulated and unpaid dividends thereon, if any,
          to the date fixed for redemption.

               In addition, upon the payment of the Series A Debentures at
          maturity, the proceeds from such payment will be applied to
          redeem Series A MIPS at a redemption price of $25 per security
          plus an amount equal to accumulated and unpaid dividends, if any,
          thereon, to such maturity date.  See "Certain Terms of the Series
          A Debentures" herein and "Description of the MIPS--Redemption
          Procedures" in the accompanying Prospectus.

               If a Special Event shall occur, Duquesne Capital may redeem
          the Series A MIPS in whole or cause Series A Debentures to be
          distributed in exchange for the Series A MIPS.  In the event of
          any such distribution, each holder of Series A MIPS would receive
          Series A Debentures in an aggregate principal amount equal to the
          aggregate liquidation preference of $25 per security on the
          Series A MIPS held by it and bearing interest at __% per annum
          from the last date on which dividends on the Series A MIPS were
          paid.  Upon any such distribution of Series A Debentures in
          exchange for the Series A MIPS, Duquesne Light will use its best
          efforts to have the Series A Debentures listed on the same
          exchange on which the Series A MIPS are listed.  After the date
          fixed for any such exchange, (i) the Series A MIPS will no longer
          be deemed to be outstanding, (ii) DTC or its nominee, as the
          record holder of the Series A MIPS will exchange the global
          certificate or certificates representing the Series A MIPS for a
          registered global certificate or certificates representing the
          Series A Debentures to be delivered upon such exchange and
          (iii) any certificates representing Series A MIPS not held by DTC
          or its nominee will be deemed to represent Series A Debentures
          having a principal amount equal to the aggregate liquidation
          preference of such Series A MIPS until such certificates are
          presented to Duquesne Capital or its agent for exchange.

          MISCELLANEOUS

               The Series A MIPS have been approved for listing on the New
          York Stock Exchange, subject to official notice of issuance.

                       CERTAIN TERMS OF THE SERIES A DEBENTURES

               THE FOLLOWING SUMMARY OF CERTAIN TERMS AND PROVISIONS OF THE
          SERIES A DEBENTURES SUPPLEMENTS THE DESCRIPTION OF THE DEBENTURES

          contribution made by the General Partner, Duquesne Light will
          issue Series A Debentures to Duquesne Capital in an aggregate
          principal amount equal to the sum of the aggregate liquidation
          preference of the Series A MIPS and the amount of such capital
          contribution.

               The entire principal amount of the Series A Debentures will
          become due and payable, together with any accrued and unpaid
          interest thereon, including Additional Interest (as defined in
          the accompanying Prospectus), if any, on May 31, 2044 (subject to
          Duquesne Light's rights and obligations to redeem the Series A
          Debentures prior to such date).  See "Redemption" below.

          INTEREST

               The Series A Debentures will bear interest at a rate of   %

          in part, at a redemption price equal to 100% of the principal
          amount thereof plus any accrued but unpaid interest, including
          Additional Interest, if any, to the date fixed for redemption. 
          In addition, the Series A Debentures may be subject to mandatory
          redemption at any time under the circumstances described under
          "Description of the Debentures and the Indenture--Mandatory
          Redemption" in the accompanying Prospectus.

                                                                  =========

               Under the terms and conditions of the Underwriting
          Agreement, the Underwriters are committed to take and pay for all
          such Series A MIPS offered hereby, if any are taken.

               The Underwriters propose to offer the Series A MIPS in part
          directly to the public at the initial public offering price set
          forth on the cover page of this Prospectus Supplement, and in
          part to certain securities dealers at such price less a
          concession of $        per security.  The Underwriters may allow,
          and such dealers may reallow, a concession not in excess of $     
          per security to certain brokers and dealers.  After the Series A
          MIPS are released for sale to the public, the offering price and
          other selling terms may from time to time be varied by the
          Representatives.

               In view of the fact that the proceeds of the sale of the
          Series A MIPS will be loaned to Duquesne Light, Duquesne Light
          has agreed, in the Underwriting Agreement, to pay to the
          Underwriters as compensation for their services an amount of $    
          per security ($     per security sold to certain institutions)
          for the accounts of the several Underwriters.

               Certain of the Underwriters engage in transactions with, and
          from time to time have performed services for, Duquesne Light in
          the ordinary course of business.

               Prior to this offering, there has been no public market for
          the Series A MIPS.  The Underwriters have advised Duquesne
          Capital and Duquesne Light that they will undertake to sell lots
          of 100 or more Series A MIPS to a minimum of 400 beneficial
          holders in order to meet one of the requirements for listing the
          Series A MIPS on the New York Stock Exchange.

               Duquesne Capital and Duquesne Light have agreed to indemnify
          the several Underwriters against certain liabilities, including
          liabilities under the Securities Act of 1933, as amended.

               Duquesne Capital and Duquesne Light have agreed, during the
          period beginning on the date of the Underwriting Agreement and
          continuing to and including the earlier of (1) the termination of
          trading restrictions for the Series A MIPS, as determined by the
          Underwriters, or (2) 30 days after the closing date, not to
          offer, sell, contract to sell or otherwise dispose of any
          Preferred Securities of Duquesne Capital, any limited partnership
          interests of Duquesne Capital or any preferred stock of Duquesne
          Light or any other securities of Duquesne Capital or Duquesne
          Light which are substantially similar to the Preferred
          Securities, or any securities convertible into or exchangeable
          for Preferred Securities, limited partnership interests,
          preferred stock or such substantially similar securities of
          either Duquesne Capital or Duquesne Light, without the prior
          written consent of the Underwriters.

                                DUQUESNE LIGHT COMPANY 

               Duquesne Capital L.P. ("Duquesne Capital"), a Delaware
          special purpose limited partnership, the sole general partner of
          which is Duquesne Light Company ("Duquesne Light"), may offer,
          from time to time, in one or more series, up to $150,000,000 of
          its Cumulative Monthly Income Preferred Securities (the "MIPS"),
          which are preferred securities ("Preferred Securities"),
          representing limited partner interests in Duquesne Capital.  The
          MIPS may be offered in amounts, at prices and on terms to be
          determined at the time of offering.  Duquesne Capital was formed
          for the sole purpose of issuing its limited partnership interests
          and lending the proceeds thereof to Duquesne  Light.  Duquesne
          Capital will lend the proceeds of the sale of the MIPS to
          Duquesne Light in return for Subordinated Deferrable Interest
          Debentures of Duquesne Light in an aggregate principal amount
          equal to the aggregate liquidation preference of the MIPS,
          bearing interest at an annual rate equal to the annual dividend
          rate on the MIPS and having certain redemption terms which
          correspond to the redemption terms for the MIPS ("Debentures").

               The payment of periodic cash distributions ("dividends") and
          payments on liquidation or redemption with respect to the MIPS,
          to the extent of funds held by Duquesne Capital and legally
          available therefor, will be guaranteed under a Payment and
          Guarantee Agreement (the "Guarantee") of Duquesne Light to the
          extent described herein.  The Guarantee and the Debentures will
          rank subordinate in right of payment to all Senior Indebtedness
          (as defined herein) of Duquesne Light.  Duquesne Capital's
          earnings will be limited to payments by Duquesne Light on the
          Debentures and other Indenture Securities (as defined herein)
          issued under the Indenture (as defined herein).  If Duquesne
          Light fails to make interest payments on the Debentures, Duquesne
          Capital will have insufficient funds to pay dividends on the MIPS
          and the Guarantee will not cover payment of such dividends.  In
          such event, the holders of MIPS may enforce certain rights in
          respect of the Debentures under the Indenture.  Interest on the
          Debentures may be deferred at the option of Duquesne Light as
          described under "Description of the Debentures and the
          Indenture--Option to Extend Interest Payment Period", and, as a
          consequence, monthly dividends on the MIPS may be deferred by
          Duquesne Capital.  See "Description of the Guarantee" and
          "Description of the Debentures and the Indenture" herein for a
          description of the terms and limitations of such obligations of
          Duquesne Light relating to the MIPS.

               Under certain circumstances described herein, Duquesne Light
          may cause Duquesne Capital to distribute the Debentures in
          exchange for MIPS.  See "Description of the MIPS--Special Event
          Redemption or Exchange".

               Certain specific terms of the MIPS and the related series of
          Debentures in respect of which this Prospectus is being delivered
          will be set forth in an accompanying Prospectus Supplement
          ("Prospectus Supplement"), including the series designation,
          number of securities and the dividend rate on MIPS, and the
          maturity and the interest rate on such Debentures and any other
          special terms.

               The MIPS will be sold directly, through agents,
          underwriters, including Goldman, Sachs & Co., or dealers as
          designated from time to time, or through a combination of such
          methods.  If agents of Duquesne Capital or any dealers or
          underwriters are involved in the sale of the MIPS in respect of
          which this Prospectus is being delivered, the names of such
          agents, dealers or underwriters and any applicable commissions or
          discounts will be set forth in or may be calculated from the
          accompanying Prospectus Supplement.  See "Plan of Distribution".
          
               This Prospectus may not be used to consummate sales of the
          MIPS unless accompanied by a Prospectus Supplement.

               This Prospectus does not contain all the information set
          forth in the Registration Statement on Form S-3, which Duquesne
          Light and Duquesne Capital have filed with the Commission under
          the Securities Act of 1933, as amended (the "Securities Act"). 
          Statements contained or incorporated by reference herein
          concerning the provisions of documents are necessarily summaries
          of such documents, and each statement is qualified in its
          entirety by reference to such Registration Statement, as amended
          by Amendment No. 1 thereto, including the documents filed as
          exhibits thereto (the "Registration Statement").

               No separate financial statements of Duquesne Capital have
          been included herein.  Duquesne Light and Duquesne Capital do not
          consider that such financial statements would be material to
          holders of MIPS because Duquesne Capital is a special purpose
          entity, has no operating history and no independent operations
          and is not engaged in, and does not propose to engage in, any
          activity other than as set forth below.  See "Description of the
          MIPS".  Duquesne Capital is a special purpose limited partnership
          organized under the laws of the State of Delaware, and Duquesne
          Light is the sole general partner.  Duquesne Capital exists for
          the sole purpose of issuing its limited partnership interests and
          lending the proceeds thereof to Duquesne Light.

                                DUQUESNE LIGHT COMPANY

               Duquesne Light was formed under the laws of Pennsylvania by
          the consolidation and merger in 1912 of three constituent
          companies.  As part of a corporate reorganization, Duquesne Light
          became a wholly-owned subsidiary of DQE, an energy services
          holding company formed in 1989.  Duquesne Light is engaged in the
          production, transmission, distribution and sale of electric
          energy.  Duquesne Light provides electric service to customers in
          Allegheny County, including the City of Pittsburgh, Pennsylvania

               Duquesne Capital is a limited partnership which was formed
          under the Delaware Revised Uniform Limited Partnership Act, as
          amended (the "Delaware Act"), on April 27, 1994.  Duquesne
          Capital was formed for the sole purpose of issuing its limited
          partnership interests and lending the proceeds thereof to
          Duquesne Light.  Duquesne Light is the sole general partner of
          Duquesne Capital (the "General Partner") and will manage the

          other Preferred Securities of Duquesne Capital will be limited
          partners in Duquesne Capital.  Duquesne Light will make capital
          contributions from time to time to the extent required so that
          the total contributions made by Duquesne Light, as General
          Partner, shall at all times be at least equal to 1% of the total
          contributions made by all partners.  Duquesne Capital will lend
          such amounts to Duquesne Light from time to time in return for
          Indenture Securities of Duquesne Light, including the Debentures. 
          The rights and obligations of Duquesne Light, as General Partner,
          and the limited partners of Duquesne Capital will be governed by

          supplier, which amounted to approximately $3.4 million for the
          year ended December 31, 1995, has been excluded.

               Earnings related to income taxes reflect a $13.5 million
          decrease for the twelve months ended December 31, 1995, and
          December 31, 1994, due to a financial statement reclassification
          related to SFAS 109.  The Ratio of Earnings to Fixed Charges
          absent this reclassification equals 2.81 and 2.67 for the twelve
          months ended December 31, 1995, and December 31, 1994,
          respectively.  The Ratio of Earnings to Fixed Charges and
          Preferred and Preference Stock Dividend Requirements absent this
          reclassification equals 2.72 and 2.57 for the twelve months ended
          December 31, 1995 and December 31, 1994, respectively.

                               DESCRIPTION OF THE MIPS

               SET FORTH BELOW IS A SUMMARY OF CERTAIN TERMS AND PROVISIONS
          OF THE MIPS.  THIS SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS
          SUBJECT TO, AND QUALIFIED IN ITS ENTIRETY BY REFERENCE TO, THE
          FORMS OF PARTNERSHIP AGREEMENT AND ACTION OF GENERAL PARTNER
          ESTABLISHING THE MIPS FILED AS EXHIBITS TO THE REGISTRATION
          STATEMENT.

          GENERAL

               The Partnership Agreement will authorize Duquesne Light as
          the General Partner, to establish various series of Preferred
          Securities, including one or more series of MIPS, having such
          designations, rights, privileges, restrictions and other terms
          and provisions as the General Partner may determine.  The MIPS
          are limited partner interests in Duquesne Capital, and may be
          issued from time to time, having terms described herein and in
          the Prospectus Supplement relating thereto.  The limited partner
          interests represented by the MIPS will have a preference with
          respect to cash distributions and amounts payable on liquidation
          over the General Partner's interest in Duquesne Capital.  The
          Action or Actions of General Partner creating the MIPS will not
          permit the issuance of any limited partnership interests of
          Duquesne Capital ranking, as to participation in profits or the
          assets of Duquesne Capital, senior to the MIPS.  

               Amounts payable in respect of the MIPS will be guaranteed by
          Duquesne Light to the extent set forth below under "Description
          of the Guarantee".

               Under certain circumstances described herein, the MIPS may
          be exchanged for Debentures of Duquesne Light.  See "Special
          Event Redemption or Exchange" below.

          DIVIDENDS

               Unless otherwise specified in a Prospectus Supplement,
          dividends on the MIPS of each series will be cumulative, will
          accumulate from the date of issue and will be payable monthly in
          arrears on the last day of each calendar month of each year
          except as otherwise described below.

               The annual dividend rate on the MIPS of each series will be
          set forth in a Prospectus Supplement relating to such series.

               The amount of dividends payable for any period will be
          computed on the basis of twelve 30-day months and a 360-day year
          and, for any period shorter than a full monthly dividend period,
          will be computed on the basis of the actual number of days
          elapsed in such period.  Payment of dividends on the MIPS is
          limited in relation to the amount of funds held by Duquesne
          Capital and legally available therefor.

               Dividends on the MIPS are required to be paid to the extent
          that, on any scheduled dividend payment date, Duquesne Capital
          has (x) funds legally available for the payment of such
          dividends, as determined by the General Partner, and (y) cash on
          hand sufficient to permit such payment.  Duquesne Capital's
          earnings will be limited to Duquesne Light's payments of interest
          on the Debentures and other Indenture Securities.  See
          "Description of the Debentures and the Indenture".  Duquesne
          Light has the right under the Indenture, from time to time, to
          extend the interest payment periods on the Debentures for up to
          60 consecutive months, and, as a consequence, monthly dividends
          on the MIPS will be deferred by Duquesne Capital (and will
          continue to accumulate but without interest on any amounts so
          deferred) during any such extended interest payment period.  See
          "Description of the Debentures and the Indenture--Option to Extend
          Interest Payment Period".

               Dividends on the MIPS will be payable to the holders thereof
          as they appear on the books and records of Duquesne Capital on
          the relevant record dates, which will be one Business Day (as
          hereinafter defined) prior to the relevant payment dates;
          provided, however, that if the MIPS of any series are not held by
          a securities depositary, the General Partner shall have the right
          to change such record dates.  Subject to any applicable laws and
          regulations and the provisions of the Partnership Agreement, each
          such payment will be made as described under "Book-Entry-Only
          Issuance" below.  In the event that any date on which dividends
          are payable on the MIPS is not a Business Day, then payment of
          the dividends payable on such date will be made on the next
          succeeding day which is a Business Day (and without any interest
          or other payment in respect of any such delay) except that, if
          such Business Day is in the next succeeding calendar year, such
          payment shall be made on the immediately preceding Business Day,
          in each case with the same force and effect, and in the same
          amount, as if made on such date.  A "Business Day" shall mean any
          day other than a day on which banking institutions in The City of
          New York or the City of Pittsburgh, Pennsylvania are authorized
          or required by law to close.

          CERTAIN RESTRICTIONS ON DUQUESNE CAPITAL

               If dividends have not been paid in full on the MIPS of any
          series, Duquesne Capital shall not:

                    (i)   pay, or set aside for payment, any dividends on
               any other Preferred Securities ranking pari passu with the
               MIPS of such series as regards participation in profits of
               Duquesne Capital ("Dividend Parity Securities"), unless, at
               the time of such payment or setting aside, there shall also
               be paid, or set aside for payment, as the case may be,
               dividends on the MIPS of such series on a pro rata basis, so
               that, after giving effect to the payment of all such
               dividends, 

                         (x)   the ratio of (a) the aggregate amount of
                    dividends paid on the MIPS of such series to (b) the
                    aggregate amount of dividends paid on such Dividend
                    Parity Securities is the same as 

                         (y)   the ratio of (a) the aggregate of all
                    accumulated arrears of unpaid dividends in respect of
                    the MIPS of such series to (b) the aggregate of all
                    accumulated arrears of unpaid dividends in respect of
                    such Dividend Parity Securities; 

                    (ii)   pay, or set aside for payment, any dividends or
               other distributions on any other securities of Duquesne
               Capital ranking junior to the MIPS of such series as to
               dividends ("Dividend Junior Securities"); or 

                    (iii)   redeem, purchase or otherwise acquire any MIPS
               of such series, any Dividend Parity Securities or any
               Dividend Junior Securities; 

          until, in each case, such time as all accumulated and unpaid
          dividends on the MIPS of such series shall have been paid in full
          for all dividend periods terminating on or prior to, in the case
          of clauses (i) and (ii), such payment and, in the case of clause
          (iii), the date of such redemption, purchase or acquisition.  

          OPTIONAL REDEMPTION

               Unless otherwise provided in a Prospectus Supplement, the
          MIPS of each series will be redeemable, at the option of Duquesne
          Capital and at the direction of Duquesne Light, in whole or in
          part from time to time, on or after the fifth anniversary of the
          last day of the month in which such MIPS are issued, upon not
          less than 30 nor more than 60 days' notice, at a redemption price
          of $25 per security, plus an amount equal to accumulated and
          unpaid dividends to the date fixed for redemption (the
          "Redemption Price"); provided, however, that prior to giving any
          such notice of redemption Duquesne Capital shall have received
          from Duquesne Light a notice of redemption of Debentures of the
          corresponding series having an aggregate principal amount equal
          to the aggregate liquidation preference of the MIPS to be
          redeemed.  In the event that fewer than all the outstanding MIPS
          of any series are to be so redeemed, the MIPS to be redeemed will
          be selected as described under "Book-Entry-Only Issuance" below. 
          If a partial redemption would result in a delisting of the MIPS
          of any series by any national securities exchange or other
          organization on which the MIPS of such series are then listed,
          Duquesne Capital may only redeem the MIPS of such series in
          whole.

          SPECIAL EVENT REDEMPTION OR EXCHANGE

               If a Special Event (as defined below) shall occur and be
          continuing, the General Partner will (i) cause Duquesne Capital
          to redeem the MIPS in whole (and not in part), upon not less than
          30 nor more than 60 days' notice, at the Redemption Price within
          90 days following the occurrence of such Special Event, or (ii)
          cause Duquesne Capital to distribute Debentures to holders of
          MIPS in exchange for such MIPS within 90 days following the
          occurrence of such Special Event.  Notwithstanding the foregoing,
          if the Special Event is solely a Tax Event (as defined below),
          neither the General Partner nor Duquesne Capital shall be
          required to elect either of the options described in (i) or (ii)
          above and may, instead, allow the MIPS to remain outstanding.

               In the event of a distribution of Debentures as described in
          (ii) above, each holder of MIPS would receive Debentures in an
          aggregate principal amount equal to the aggregate liquidation
          preference of $25 per security on the MIPS held by it and bearing
          interest at a rate per annum equal to the dividend rate per annum
          on such MIPS from the last date on which dividends on such MIPS
          were paid.  Under such circumstances, if there are no other
          Preferred Securities then outstanding, Duquesne Light may cause
          Duquesne Capital to be dissolved.

               After the date fixed for any such exchange, (i) the MIPS
          will no longer be deemed to be outstanding, (ii) the Depositary
          (as hereinafter defined) or its nominee, as the record holder of
          the MIPS, will exchange the global certificate or certificates
          representing the MIPS for a registered global certificate or
          certificates representing the Debentures to be delivered upon
          such exchange and (iii) any certificates representing shares of
          MIPS not held by the Depositary or its nominee will be deemed to
          represent Debentures having a principal amount equal to the
          liquidation preference of such MIPS until such certificates are
          presented to Duquesne Light or its agent for exchange.

               "Special Event" means an Investment Company Event or a Tax
          Event.

               "Investment Company Event" means the occurrence of a change
          in law or regulation or a written change in official
          interpretation of law or regulation by any legislative body,
          court, governmental agency or regulatory authority (a "Change in
          40 Act Law") to the effect that Duquesne Capital is or will be
          considered an "investment company" required to be registered
          under the Investment Company Act of 1940, as amended (the "1940
          Act"), which Change in 40 Act Law becomes effective on or after
          the date of the first issuance of MIPS of such series; provided
          that no Investment Company Event shall be deemed to have occurred
          if Duquesne Light or Duquesne Capital shall have obtained a
          written opinion of nationally recognized independent counsel
          experienced in practice under the 1940 Act, to the effect that
          Duquesne Light or Duquesne Capital has successfully taken either
          of the steps set forth in (i) or (ii) below to avoid such Change
          in 40 Act Law so that in the opinion of such counsel,
          notwithstanding such Change in 40 Act Law, Duquesne Capital is
          not required to be registered as an "investment company" within
          the meaning of the 1940 Act.  Such steps shall be either (i)
          issuing an additional or supplemental irrevocable and
          unconditional guarantee (x) of accumulated and unpaid dividends
          (whether or not moneys are legally available therefor) on the
          MIPS and (y) upon a liquidation of Duquesne Capital, of the full
          amount of the Liquidation Distribution (as hereinafter defined)
          on the MIPS (regardless of the amount of assets of Duquesne
          Capital otherwise available for distribution in such
          liquidation), or (ii) the use of any other reasonable measures
          that do not adversely affect holders of MIPS in any material
          respect.

               "Tax Event" means that Duquesne Light or Duquesne Capital
          shall have obtained an opinion of nationally recognized
          independent tax counsel experienced in such matters to the effect
          that, as a result of any amendment to, or change (including any
          announced prospective change) in, the laws (or any regulations
          thereunder) of the United States or any political subdivision or
          taxing authority thereof or therein affecting taxation, or any
          amendment to or change in an official interpretation or
          application of such laws or regulations, which amendment or
          change is effective on or after the date of the first issuance of
          MIPS of such series, and which change cannot be avoided by the
          use of any reasonable measures available to Duquesne Light or
          Duquesne Capital, there is a substantial increase in risk that
          (i) Duquesne Capital is subject to Federal income tax with
          respect to interest received on the Debentures, (ii) interest
          payable on the Debentures will not be deductible for Federal
          income tax purposes or (iii) Duquesne Capital is subject to more
          than a de minimis amount of other taxes, duties or other
          governmental charges.

          REDEMPTION PROCEDURES

               If at any time Duquesne Light (i) pays at maturity or (ii)
          redeems Debentures of any series as described under "Description
          of the Debentures and the Indenture--Optional Redemption", the
          proceeds from such payment or redemption of principal of such
          Debentures will be applied to redeem MIPS of the related series
          at the Redemption Price upon not less than 30 nor more than 60
          days' notice (except that no such notice will be required in the
          case of (i)).

               If (a) Duquesne Capital gives a notice of redemption in
          respect of MIPS of any series (which notice will be irrevocable)
          or (b) MIPS of any series shall become redeemable by virtue of
          the maturity of the related Debentures, then, on the date fixed
          for redemption (the "Redemption Date"), which in the case of (b)
          shall be the applicable Debenture maturity date, Duquesne Capital
          will pay the applicable Redemption Price to the record holders of
          such MIPS.  See "Book-Entry-Only Issuance" below.  If notice of
          redemption has been given and payment or provision for payment
          has been made on the Redemption Date as required, then upon such
          date, all rights of holders of such MIPS so called for redemption
          will cease, except the right of such holders to receive the
          Redemption Price, but without interest.  In the event that any
          Redemption Date is not a Business Day, payment of the Redemption
          Price payable on such date will be made on the next succeeding
          day which is a Business Day (and without any interest or other
          payment in respect of any such delay), except that, if such
          Business Day falls in the next calendar year, such payment will
          be made on the immediately preceding Business Day.  In the event
          that payment of the Redemption Price in respect of any MIPS is
          not paid either by Duquesne Capital or by Duquesne Light pursuant
          to the Guarantee described under "Description of the Guarantee",
          dividends on such MIPS will continue to accumulate (but without
          any interest on amounts so accumulating) from the original
          Redemption Date to the date of payment, in which case the actual
          payment date will be considered the Redemption Date for purposes
          of calculating the Redemption Price.

               Subject to the foregoing and applicable law (including,
          without limitation, Federal securities laws), Duquesne Light or
          its affiliates may at any time and from time to time purchase
          outstanding MIPS by tender, in the open market or by private
          agreement.  In the event that Duquesne Light surrenders any MIPS
          to Duquesne Capital, Duquesne Capital will distribute to or upon
          the order of Duquesne Light, Debentures of the corresponding
          series in aggregate principal amount equal to the aggregate
          liquidation preference on the MIPS so surrendered.

          LIQUIDATION DISTRIBUTION

               In the event of any voluntary or involuntary dissolution,
          liquidation or winding up of Duquesne Capital, the holders of the
          MIPS of each series at the time outstanding will be entitled to
          receive out of the assets of Duquesne Capital available for
          distribution to partners of Duquesne Capital, after satisfaction
          of liabilities to creditors, if any, as required by the Delaware
          Act, before any distribution of assets is made to the General
          Partner or any other series of Preferred Securities ranking
          junior to the MIPS of such series with respect to participation
          in the assets of Duquesne Capital, but together with the holders
          of every other series of Preferred Securities outstanding, if
          any, ranking pari passu with the MIPS of such series with respect
          to participation in the assets of Duquesne Capital ("Liquidation
          Parity Securities"), an amount equal to the aggregate of the
          liquidation preference of $25 per security plus an amount equal
          to all accumulated and unpaid dividends on the MIPS of such
          series to the date of payment (the "Liquidation Distribution").

               If, upon any such liquidation, the Liquidation Distribution
          for MIPS  of any series can be paid only in part because Duquesne
          Capital has insufficient assets available to pay in full the
          aggregate Liquidation Distribution for such series and the
          aggregate maximum liquidation distributions on the Liquidation
          Parity Securities, then the amounts payable directly by Duquesne
          Capital on the MIPS of such series and on such Liquidation Parity
          Securities shall be paid on a pro rata basis, so that

               (i)  the ratio of (x) the aggregate amount paid in respect
               of the Liquidation Distribution to (y) the aggregate amount
               paid in respect of liquidation distributions on the
               Liquidation Parity Securities is the same as 

               (ii) the ratio of (x) the aggregate Liquidation Distribution
               to (y) the aggregate maximum liquidation distributions on
               the Liquidation Parity Securities.

               Pursuant to the Partnership Agreement, Duquesne Capital
          shall be dissolved and its affairs shall be wound up: (i) on
          December 31, 2049, the expiration of the term of Duquesne
          Capital, (ii) upon the withdrawal, removal or bankruptcy of the
          General Partner, or the assignment by the General Partner of its
          general partner interest in Duquesne Capital or the occurrence of
          any other event that results in the General Partner ceasing to be
          a general partner of Duquesne Capital under the Delaware Act,
          except for a transfer to a permitted successor of Duquesne Light
          under the Indenture, unless in any such case the business of
          Duquesne Capital is continued in accordance with the Delaware
          Act, (iii) upon the entry of decree of a judicial dissolution, or
          (iv) upon the written consent of all partners of Duquesne
          Capital, including the holders of the Preferred Securities.

          SOURCE OF PAYMENT FOR THE MIPS

               Duquesne Capital is a special purpose limited partnership
          formed for the sole purpose of issuing its limited partnership
          interests and lending the proceeds thereof to Duquesne Light in
          return for debt securities of Duquesne Light.  The proceeds of
          the MIPS will be loaned to Duquesne Light in return for
          Debentures.  Duquesne Capital's earnings will be limited to
          payments by Duquesne Light on the Debentures and other Indenture
          Securities.

               Dividends on the MIPS and payments on liquidation or
          redemption with respect to the MIPS must be paid to the extent of
          funds held by Duquesne Capital and legally available to make such
          payments.  Under the terms of the Guarantee as described under
          "Description of the Guarantee--General" herein, such payments
          required to be made on the MIPS will be irrevocably and
          unconditionally guaranteed by Duquesne Light.  Because the
          payment terms of the Debentures will generally correspond to the
          payment terms of the MIPS, Duquesne Capital is expected to have
          sufficient funds to make payments on the MIPS so long as Duquesne
          Light is not in default in payment of the Debentures.  In
          addition, because Duquesne Light will covenant in the Guarantee
          to timely perform all of its duties as General Partner, including
          the duty to pay dividends on the MIPS and the duty to pay all
          costs and expenses of Duquesne Capital, it is expected that all
          payments on the Debentures will be available for the payment of
          dividends on the MIPS.  Duquesne Light and Duquesne Capital
          believe that the obligations of Duquesne Light under the
          Guarantee, the Partnership Agreement and the Debentures, taken
          together, are substantially equivalent to a full and
          unconditional guarantee by Duquesne Light of payments required to
          be made on the MIPS.  The Guarantee will be one of payment and
          not of collection, and holders of MIPS may enforce the Guarantee
          directly against Duquesne Light, without first proceeding against
          Duquesne Capital.  If Duquesne Light fails to make interest
          payments on the Debentures, Duquesne Capital will have
          insufficient funds to pay dividends on the MIPS, and the
          Guarantee will not cover payment of such dividends.  In such
          event, the holders of MIPS may enforce certain rights in respect
          of the Debentures under the Indenture.  In addition, under
          certain circumstances, to the fullest extent permitted by
          applicable law, holders of MIPS will have the right to appoint a
          Special Representative to enforce Duquesne Capital's rights as
          holder of the Debentures.

               See "Description of the Guarantee" and "Description of the
          Debentures and the Indenture" herein for a description of the
          terms and limitations of the obligations of Duquesne Light
          relating to the MIPS.

          MERGER, CONSOLIDATION, AMALGAMATION, ETC. OF DUQUESNE CAPITAL

               The General Partner is authorized and directed to conduct
          its affairs and to operate Duquesne Capital in such a way that
          Duquesne Capital would not be deemed to be an "investment
          company" required to be registered under the 1940 Act or taxed as
          a corporation for Federal income tax purposes and so that the
          Debentures will be treated as indebtedness of Duquesne Light for
          Federal income tax purposes.  In this connection, the General
          Partner is authorized to take any action not inconsistent with
          applicable law, the Certificate of Limited Partnership or the
          Partnership Agreement and that does not adversely affect the
          interests of holders of MIPS that the General Partner determines
          in its discretion to be necessary or desirable for such purposes.

               Duquesne Capital may not consolidate, amalgamate, merge with
          or into, or be replaced by, or convey, transfer or lease its
          properties and assets substantially as an entirety to any
          partnership, corporation or other body, except as described
          below.  Duquesne Light, as General Partner, may, without the
          consent of the holders of the MIPS, cause Duquesne Capital to
          consolidate, amalgamate, merge with or into, or be replaced by,
          or convey or transfer its properties and assets substantially as
          an entirety to, a Delaware limited partnership or "other business
          entity" (as defined in the Delaware Act but not including any
          general partnership) organized under the laws of any state of the
          United States or the Turks and Caicos Islands, provided that (i)
          such successor entity either (x) expressly assumes all of the
          obligations of Duquesne Capital under the MIPS or (y) substitutes
          for the MIPS other securities having substantially the same terms
          as the MIPS (the "Successor Securities") so long as the Successor
          Securities rank with respect to participation in the profits and
          assets of the successor entity, at least as high as the MIPS rank
          with respect to participation in the profits and assets of
          Duquesne Capital, (ii) Duquesne Light expressly acknowledges such
          successor entity as the holder of the Debentures relating to the
          MIPS, (iii) such merger, consolidation, amalgamation,
          replacement, conveyance or transfer does not cause the MIPS to be
          delisted by any national securities exchange or other
          organization on which the MIPS are then listed unless the MIPS
          are promptly relisted, or the Successor Securities are promptly
          listed, by such exchange or other organization, (iv) such merger,
          consolidation, amalgamation, replacement, conveyance or transfer
          does not cause the MIPS to be downgraded or the Successor
          Securities to be rated lower than the MIPS immediately prior to
          such merger, consolidation, amalgamation, replacement, conveyance
          or transfer by any "nationally recognized statistical rating
          organization", as that term is defined by the Commission for
          purposes of Rule 436(g)(2) under the Securities Act, (v) such
          merger, consolidation, amalgamation, replacement, conveyance or
          transfer does not adversely affect the powers, preferences and
          other special rights of holders of MIPS in any material respect,
          and (vi) prior to such merger, consolidation, amalgamation,
          replacement, conveyance or transfer Duquesne Light has received
          an opinion of nationally recognized independent counsel to
          Duquesne Capital experienced in such matters to the effect that
          (w) holders of MIPS will not recognize any gain or loss for
          Federal income tax purposes as a result of the merger,
          consolidation, amalgamation, replacement, conveyance or transfer,
          (x) such successor entity will be treated as a partnership for
          Federal income tax purposes, (y) following such merger,
          consolidation, amalgamation, replacement, conveyance or transfer,
          Duquesne Light and such successor entity will be in compliance
          with the 1940 Act without registering thereunder as an investment
          company, and (z) such merger, consolidation, amalgamation,
          replacement, conveyance or transfer will not adversely affect the
          limited liability of holders of MIPS.

          VOTING RIGHTS

               Except as provided below and under "Description of the
          Guarantee--Amendments and Assignments" and as otherwise required 
          by law and the Partnership Agreement, the holders of the MIPS will
          have no voting rights. 

               If (i) Duquesne Capital fails to pay dividends in full on
          the MIPS of any series for any period of 18 consecutive months,
          (ii) an Event of Default with respect to the corresponding series
          of Debentures (as described under "Description of the Debentures
          and the Indenture--Events of Default; Remedies") occurs and is
          continuing, or (iii) Duquesne Light is in default on any of its
          payment or other obligations under the Guarantee (as described
          under "Description of the GuaranteeCertain Covenants of Duquesne
          Light"), then, to the fullest extent permitted by applicable law,
          the holders of the outstanding MIPS of such series, together with
          the holders of any other series of Preferred Securities having
          the right to vote for the appointment of a special representative
          (the "Special Representative") in such event, acting as a single
          class, will be entitled, by vote of holders of a majority in
          aggregate liquidation preference of all Preferred Securities
          having the right to vote, to appoint and authorize a Special
          Representative to enforce Duquesne Capital's rights under the
          corresponding Indenture Securities (as hereinafter defined),
          including the corresponding Debentures, and the Indenture against
          Duquesne Light, enforce the obligations undertaken by Duquesne
          Light under the Guarantee and pay dividends on the MIPS of such
          series (to the extent Duquesne Capital has funds legally
          available for the payment of such dividends and cash on hand
          sufficient to permit such payment).

               For purposes of determining whether Duquesne Capital has
          failed to pay dividends in full for 18 consecutive months,
          dividends shall be deemed to remain in arrears, notwithstanding
          any payments in respect thereof, until full cumulative dividends
          have been or contemporaneously are set aside and paid with
          respect to all monthly dividend periods terminating on or prior
          to the date of payment of such full cumulative dividends.  Not
          later than 30 days after such right to appoint a Special
          Representative arises, the General Partner will convene a general
          meeting for the above purpose.  If the General Partner fails to
          convene such meeting within such 30-day period, the holders of
          10% in aggregate liquidation preference of the outstanding MIPS
          of any series will be entitled to convene such meeting.  The
          provisions of the Partnership Agreement relating to the convening
          and conduct of the general meetings of partners of Duquesne
          Capital will apply with respect to any such meeting.  Any Special
          Representative so appointed shall vacate office immediately if
          Duquesne Capital (or Duquesne Light pursuant to the Guarantee)
          shall have paid in full all accumulated and unpaid dividends on
          the MIPS of such series or such Event of Default or default under
          the Guarantee, as the case may be, shall have been cured. 
          Notwithstanding the appointment of any such Special
          Representative, Duquesne Light shall retain its rights under the
          Indenture to extend the interest payment period as provided under
          "Description of the Debentures and the Indenture--Option to Extend
          Interest Payment Period".  

               If any proposed amendment to the Partnership Agreement
          provides for, or the General Partner otherwise proposes to
          effect, (x) any action which would adversely affect the rights,
          preferences and privileges of the holders of MIPS of any series,
          whether by way of amendment to the Partnership Agreement or
          otherwise (including, without limitation, the authorization or
          issuance of any limited partnership interests of Duquesne Capital
          ranking, as to participation in the profits or assets of Duquesne
          Capital, senior to the MIPS of such series), or (y) the
          dissolution, liquidation or winding up of Duquesne Capital (other
          than in connection with a distribution of Debentures and
          dissolution of Duquesne Capital upon the occurrence of a Special
          Event or as described under "Description of the MIPS--Merger,
          Consolidation, Amalgamation, etc. of Duquesne Capital" above),
          then holders of outstanding MIPS of such series will be entitled
          to vote on such amendment or proposed action of the General
          Partner (but not on any other amendment or action) together as a
          class with, in the case of an action described in clause (x)
          above which would equally adversely affect the rights,
          preferences or privileges of holders of any Dividend Parity
          Securities or any Liquidation Parity Securities, holders of such
          Dividend Parity Securities or such Liquidation Parity Securities,
          as the case may be, or, in the case of any amendment described in
          clause (y) above, holders of all Liquidation Parity Securities,
          and such amendment or action shall not be effective except with
          the approval of the holders of 66 2/3% in aggregate liquidation 
          preference of such class; provided, however, that no such approval 
          shall be required if the dissolution, liquidation or winding up of 
          Duquesne Capital is proposed or initiated pursuant to the Partnership 
          Agreement or upon the initiation of proceedings, or after proceedings 
          have been initiated, for the dissolution, liquidation or winding up 
          of Duquesne Light.

               The rights of holders of MIPS of any series will be deemed
          not to be adversely affected by the creation or issue of, and no
          vote will be required for the creation of, any further limited
          partnership interests of Duquesne Capital ranking junior to, or
          pari passu with, the MIPS of such series with regard to
          participation in the profits or assets of Duquesne Capital. 
          Holders of MIPS will have no preemptive rights.  

               The Partnership Agreement provides that the General Partner
          will not permit or cause Duquesne Capital to file a voluntary
          petition in bankruptcy without the affirmative vote of the
          holders of 66 2/3% in aggregate liquidation preference of the 
          outstanding Preferred Securities.

               If any action is, by the terms of the Indenture, not
          permitted to be taken by Duquesne Capital without the consent of
          holders of Preferred Securities or any Special Representative,
          the General Partner shall not, without such requisite consent,
          take any such action.

               Any required approval of holders of MIPS of any series may
          be given at a separate meeting of such holders convened for such
          purpose, at a general meeting of partners of Duquesne Capital or
          pursuant to written consent.  Duquesne Capital will cause a
          notice of any meeting at which holders of the MIPS of such series
          are entitled to vote, or of any matter upon which action by
          written consent of such holders is to be taken, to be mailed to
          each holder of record of such MIPS.  Each such notice will
          include a statement setting forth (i) the date of such meeting or
          the date by which such action is to be taken, (ii) a description
          of any matter on which such holders are entitled to vote or upon
          which written consent is sought and (iii) instructions for the
          delivery of proxies or consents.

               No vote or consent of the holders of the MIPS will be
          required for Duquesne Capital to redeem and cancel MIPS in
          accordance with the Partnership Agreement. 

               Notwithstanding that holders of MIPS are entitled to vote or
          consent under any of the circumstances described above, the
          holders of MIPS that are owned by Duquesne Light or any affiliate
          of Duquesne Light shall not be entitled to vote or consent and
          shall, for the purposes of such vote or consent, be treated as if
          they were not outstanding.

          BOOK-ENTRY-ONLY ISSUANCE

               The Depository Trust Company ("DTC") will initially act as
          securities depository for the MIPS.  The MIPS will be issued only
          as fully-registered securities registered in the name of Cede &
          Co. (DTC's nominee).  DTC and any other depositary which may
          replace DTC as depositary for the MIPS are sometimes referred to
          herein as the "Depositary."  One or more fully-registered global
          certificates will be issued for each series, representing in the
          aggregate the total number of MIPS for such series, and will be
          deposited with DTC.

               DTC is a limited-purpose trust company organized under the
          New York Banking Law, a "banking organization" within the meaning
          of the New York Banking Law, a member of the Federal Reserve
          System, a "clearing corporation" within the meaning of the New
          York Uniform Commercial Code, and a "clearing agency" registered
          pursuant to the provisions of Section 17A of the Exchange Act. 
          DTC holds securities that its participants ("Participants")
          deposit with DTC.  DTC also facilitates the settlement among
          Participants of securities transactions, such as transfers and
          pledges, in deposited securities through electronic computerized
          book-entry changes in Participants' accounts, thereby eliminating
          the need for physical movement of securities certificates. 
          Direct Participants ("Direct Participants") include securities
          brokers and dealers, banks, trust companies, clearing
          corporations, and certain other organizations.  DTC is owned by a
          number of its Direct Participants and by The New York Stock
          Exchange, Inc., the American Stock Exchange, Inc., and the
          National Association of Securities Dealers, Inc.  Access to the
          DTC system is also available to others such as securities brokers
          and dealers, banks and trust companies that clear through or
          maintain a custodial relationship with a Direct Participant,
          either directly or indirectly ("Indirect Participants").  The
          rules applicable to DTC and its Participants are on file with the
          Commission.

               Purchases of MIPS under the DTC system must be made by or
          through Direct Participants, which will receive a credit for the
          MIPS on DTC's records.  The ownership interest of each actual
          purchaser of MIPS ("Beneficial Owner") is in turn to be recorded
          on the Direct and Indirect Participants' records.  Beneficial
          Owners will not receive written confirmation from DTC of their
          purchases, but Beneficial Owners are expected to receive written
          confirmations providing details of the transactions, as well as
          periodic statements of their holdings, from the Direct or
          Indirect Participants through which the Beneficial Owners
          purchased MIPS.  Transfers of ownership interests in the MIPS are
          to be accomplished by entries made on the books of Participants
          acting on behalf of Beneficial Owners.  Beneficial Owners will
          not receive certificates representing their ownership interests
          in MIPS, except in the event that use of the book-entry system
          for the MIPS is discontinued.

               To facilitate subsequent transfers, all MIPS deposited by
          Participants with DTC are registered in the name of Cede & Co. 
          DTC has no knowledge of the actual Beneficial Owners of the MIPS; 
          DTC's records reflect only the identity of the Direct
          Participants to whose accounts such MIPS are credited, which may
          or may not be the Beneficial Owners.  The Participants will
          remain responsible for keeping account of their holdings on
          behalf of their customers.

               Conveyance of notices and other communications by DTC to
          Direct Participants, by Direct Participants to Indirect
          Participants, and by Direct Participants and Indirect
          Participants to Beneficial Owners will be governed by
          arrangements among them, subject to any statutory or regulatory
          requirements as may be in effect from time to time.

               Redemption notices will be sent to Cede & Co.  If less than
          all of the MIPS of any series are being redeemed, DTC's practice
          is to determine by lot the amount of the interest of each Direct
          Participant in such series to be redeemed.

               Although voting with respect to the MIPS is limited, in
          those cases where a vote is required, neither DTC nor Cede & Co.
          will consent or vote with respect to MIPS.  Under its usual
          procedures, DTC would mail its Omnibus Proxy to Duquesne Capital
          as soon as possible after the record date.  The Omnibus Proxy
          assigns Cede & Co.'s consenting or voting rights to those Direct
          Participants to whose accounts the MIPS are credited on the
          record date (identified in a listing attached to the Omnibus
          Proxy).

               Dividend payments on the MIPS will be made to DTC.  DTC's
          practice is to credit Direct Participants' accounts on the
          relevant payable date in accordance with their respective
          holdings shown on DTC's records unless DTC has reason to believe
          that it will not receive payments on such payable date.  Payments
          by Participants to Beneficial Owners will be governed by standing
          instructions and customary practices, as is the case with
          securities held for the accounts of customers in bearer form or
          registered in "street name,"  and will be the responsibility of
          such Participant and not of DTC, Duquesne Capital or Duquesne
          Light, subject to any statutory or regulatory requirements as may
          be in effect from time to time.  Payment of dividends to DTC is
          the responsibility of Duquesne Capital, disbursement of such
          payments to Direct Participants is the responsibility of DTC, and
          disbursement of such payments to the Beneficial Owners is the
          responsibility of Direct Participants and Indirect Participants.

               Except as provided herein, a Beneficial Owner will not be
          entitled to receive physical delivery of MIPS.  Accordingly, each
          Beneficial Owner must rely on the procedures of DTC to exercise
          any rights under the MIPS.

               DTC may discontinue providing its services as securities
          depository with respect to the MIPS at any time by giving
          reasonable notice to Duquesne Capital.  Under such circumstances,
          in the event that a successor securities depository is not
          obtained, MIPS certificates are required to be printed and
          delivered.  Additionally, Duquesne Capital (with the consent of
          Duquesne Light) may decide to select another Depositary for the
          MIPS or to discontinue use of the system of book-entry transfers
          through DTC (or a successor Depositary).  In the latter event,
          certificates for the MIPS will be printed and delivered.

               The information in this section concerning DTC and DTC's
          book-entry system has been obtained from DTC.  Duquesne Capital
          and Duquesne Light believe such information to be reliable, but
          neither Duquesne Capital nor Duquesne Light takes any
          responsibility for the accuracy thereof.

               None of Duquesne Light, Duquesne Capital, any paying agent
          or any other agent of Duquesne Light or Duquesne Capital will
          have any responsibility or liability for any aspect of the
          records relating to or payments made on account of beneficial
          ownership interests in MIPS or for maintaining, supervising or
          reviewing any records relating to such beneficial ownership
          interests.

          REGISTRAR, TRANSFER AGENT AND PAYING AGENT

               Duquesne Light will act as registrar, transfer agent and
          paying agent for the MIPS.

               Registration of transfers of MIPS will be effected without
          charge by or on behalf of Duquesne Capital, but upon payment in
          respect of any tax or other governmental charges which may be
          imposed in relation to it, together with the giving of such
          indemnity as Duquesne Capital or Duquesne Light may require.

               Neither Duquesne Light nor Duquesne Capital will be required
          to register or cause to be registered the transfer of any MIPS
          which have been called for redemption.

                             DESCRIPTION OF THE GUARANTEE

               SET FORTH BELOW IS A SUMMARY OF CERTAIN TERMS AND PROVISIONS
          OF THE PAYMENT AND GUARANTEE AGREEMENT (THE "GUARANTEE") WHICH
          WILL BE EXECUTED AND DELIVERED BY DUQUESNE LIGHT FOR THE BENEFIT
          OF THE HOLDERS OF ANY SERIES FROM TIME TO TIME OF THE PREFERRED
          SECURITIES.  THIS SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS
          SUBJECT TO, AND QUALIFIED IN ITS ENTIRETY BY REFERENCE TO, THE
          FORM OF GUARANTEE FILED AS AN EXHIBIT TO THE REGISTRATION
          STATEMENT. 

          GENERAL

               Duquesne Light will irrevocably and unconditionally agree,
          to the extent set forth herein, to pay in full, to the holders of
          the Preferred Securities of each series (including any series of
          MIPS), the Guarantee Payments (as defined below), as and when
          due, regardless of any defense, right of set-off or counterclaim
          which Duquesne Capital may have or assert.  As used herein,
          Guarantee Payments means the following payments, without
          duplication, to the extent not paid by Duquesne Capital (the
          "Guarantee Payments"): (i) any accumulated and unpaid dividends
          on the Preferred Securities of such series, but only to the
          extent that Duquesne Capital has (a) funds legally available for
          the payment of such dividends, as determined by the General
          Partner, and (b) cash on hand sufficient to make such payment;
          (ii) the Redemption Price payable with respect to Preferred
          Securities of such series called for redemption by Duquesne
          Capital, but only to the extent that Duquesne Capital has (a)
          funds legally available for the payment of such Redemption Price,
          as determined by the General Partner, and (b) cash on hand
          sufficient to make such payment; and (iii) upon a liquidation of
          Duquesne Capital, the lesser of (a) the Liquidation Distribution
          and (b) the amount of assets of Duquesne Capital legally
          available to Duquesne Capital for distribution to holders of
          Preferred Securities.  Duquesne Light's obligation to make a
          Guarantee Payment may be satisfied by direct payment of the
          required amounts by Duquesne Light to holders of Preferred
          Securities or by causing Duquesne Capital to pay such amounts to
          such holders.

               If Duquesne Light fails to make payments of principal of or
          interest on the Debentures, Duquesne Capital will not have
          sufficient funds to make corresponding payments in respect of the
          Redemption Price or Liquidation Distribution, as the case may be,
          of, or dividends on, the MIPS.  The Guarantee does not cover
          payment of amounts in respect of the MIPS to the extent that
          Duquesne Capital does not have legally available funds for the
          payment thereof and cash on hand sufficient to make such payment. 
          In such event, a holder of MIPS may enforce certain rights in
          respect of the Debentures under the Indenture.  See "Description
          of the Debentures and the Indenture--Enforcement of Certain Rights
          by Holders of MIPS".

          CERTAIN COVENANTS OF DUQUESNE LIGHT

               In the Guarantee, Duquesne Light will covenant that, so long
          as any Preferred Securities remain outstanding, Duquesne Light
          shall not declare or pay any dividend on, or redeem, purchase,
          acquire or make a liquidation payment with respect to, any of its
          capital stock or make any guarantee payments with respect to the
          foregoing (other than payments under the Guarantee) if at such
          time Duquesne Light is in default with respect to its payment or
          other obligations under the Guarantee or there has occurred and
          is continuing a payment default (whether before or after the
          expiration of any period of grace) or an Event of Default under
          the Indenture.

               In the Guarantee, Duquesne Light will also covenant that, so
          long as any Preferred Securities of any series remain
          outstanding, it will (i) not voluntarily (to the extent permitted
          by law) dissolve, liquidate or wind up Duquesne Capital;
          (ii) remain the sole General Partner of Duquesne Capital and
          timely perform all of its duties as General Partner of Duquesne
          Capital (including the duty to pay dividends on the Preferred
          Securities), provided that any permitted successor of Duquesne
          Light under the Indenture may succeed to Duquesne Light's duties
          as General Partner; and (iii) use its reasonable efforts to cause
          Duquesne Capital to remain a limited partnership (or permitted
          successor under the Partnership Agreement) and otherwise continue
          to be treated as a partnership for Federal income tax purposes.

          AMENDMENTS AND ASSIGNMENT

               Except with respect to any changes which do not adversely
          affect the rights of holders of Preferred Securities of any
          series (in which case no vote will be required), the Guarantee
          may be amended only with the prior approval of the holders of not
          less than 66 2/3% in aggregate liquidation preference of the 
          outstanding Preferred Securities of each affected series
          (voting together as one class).  All guarantees and agreements
          contained in the Guarantee will bind the successors, assigns,
          receivers and trustees of Duquesne Light and will inure to the
          benefit of the holders of the Preferred Securities.

          TERMINATION OF THE GUARANTEE

               The Guarantee will terminate and be of no further force and
          effect upon full payment of the Redemption Price of all Preferred
          Securities or upon full payment of the amounts payable upon
          liquidation of Duquesne Capital.  The Guarantee will continue to
          be effective or will be reinstated, as the case may be, if at any
          time any holder of Preferred Securities must restore payment of
          any sums paid under the Preferred Securities or the Guarantee.

          STATUS OF THE GUARANTEE

               The Guarantee will constitute an unsecured obligation of
          Duquesne Light and will rank, like the Debentures and other
          Indenture Securities, subordinate in right of payment to all
          Senior Indebtedness (as hereinafter defined).  The Guarantee
          provides that each holder of Preferred Securities by acceptance
          thereof agrees that (1) amounts payable under the Guarantee will
          be subordinate in right of payment to amounts payable upon the
          Senior Indebtedness to the same extent that amounts payable under
          the Indenture and in respect of Indenture Securities (including
          the Debentures) are so subordinated and (2) the subordination
          provisions of the Indenture applicable to holders of Indenture
          Securities will be equally applicable to it.  For a discussion of
          the subordination provisions relating to the Debentures and other
          Indenture Securities, see "Description of the Debentures and the
          Indenture--Subordination".

               The Guarantee will constitute a guarantee of payment and not
          of collection.  A holder of Preferred Securities may enforce the
          Guarantee directly against Duquesne Light, and Duquesne Light
          will waive any right or remedy to require that any action be
          brought against Duquesne Capital or any other person or entity
          before proceeding against Duquesne Light.  The Guarantee will not
          be discharged except by payment of the Guarantee Payments in full
          to the extent not paid by Duquesne Capital and by complete
          performance of all obligations under the Guarantee.

          GOVERNING LAW

               The Guarantee will be governed by and construed and
          interpreted in accordance with the laws of the State of New York.


                   DESCRIPTION OF THE DEBENTURES AND THE INDENTURE

               SET FORTH BELOW IS A SUMMARY OF CERTAIN TERMS AND PROVISIONS
          OF THE INDENTURE AND THE DEBENTURES TO BE ISSUED THEREUNDER THAT
          WILL EVIDENCE THE LOANS TO BE MADE BY DUQUESNE CAPITAL TO
          DUQUESNE LIGHT OF THE PROCEEDS OF MIPS AND DUQUESNE LIGHT'S
          RELATED CAPITAL CONTRIBUTIONS TO DUQUESNE CAPITAL.  THIS SUMMARY
          DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT TO, AND QUALIFIED
          IN ITS ENTIRETY BY REFERENCE TO, THE DETAILED PROVISIONS OF THE
          FORMS OF INDENTURE AND OFFICER'S CERTIFICATE ESTABLISHING THE
          DEBENTURES FILED AS EXHIBITS TO THE REGISTRATION STATEMENT. 
          UNDER CERTAIN CIRCUMSTANCES FOLLOWING THE OCCURRENCE OF A SPECIAL
          EVENT, DEBENTURES MAY BE DISTRIBUTED TO THE HOLDERS OF MIPS AND
          DUQUESNE CAPITAL MAY BE DISSOLVED.  SEE "DESCRIPTION OF THE 
          MIPS--SPECIAL EVENT REDEMPTION OR EXCHANGE".

          GENERAL

               Pursuant to an Indenture (the "Indenture"), between Duquesne
          Light and The First National Bank of Chicago, trustee (the
          "Indenture Trustee"), Duquesne Light will issue to Duquesne
          Capital, with respect to each series of MIPS issued and sold by
          Duquesne Capital, a series of Monthly Income Subordinated
          Debentures (the "Debentures"), in an aggregate principal amount
          equal to the aggregate liquidation preference of such series of
          MIPS and the related capital contribution by Duquesne Light,
          bearing interest at an annual rate equal to the annual dividend
          rate on such series of MIPS and having certain other terms which
          correspond to the terms of such series of MIPS.

               Unless otherwise provided in a Prospectus Supplement, the
          entire principal amount of all Debentures will become due and
          payable, together with any accrued and unpaid interest thereon,
          including Additional Interest (as hereinafter defined), if any,
          on May 31, 2044. 

               The Indenture provides that, in addition to the Debentures,
          additional subordinated debentures may be issued thereunder,
          without limitation as to the aggregate principal amount, provided
          that such securities are issued to evidence loans by Duquesne
          Capital of the proceeds of the issuance of Preferred Securities
          and related capital contributions by Duquesne Light to Duquesne
          Capital.  The Debentures and all other subordinated debentures
          hereafter issued under the Indenture are collectively referred to
          as the "Indenture Securities".  The Indenture does not limit the
          amount of other debt, secured or unsecured, which may be issued
          by Duquesne Light.  The Indenture Securities will be subordinate
          and junior to all Senior Indebtedness of Duquesne Light.  As of
          December 31, 1995, Duquesne Light had approximately $1.7 billion
          of Senior Indebtedness outstanding (exclusive of certain
          guarantees and other contingent obligations, but inclusive of
          capitalized lease obligations and current installments and short-
          term notes payable).

               The Restated Articles of Incorporation of Duquesne Light
          provide that Duquesne Light may not issue any unsecured
          indebtedness without the consent of the holders of two-thirds of
          its outstanding preferred stock, except for certain limited
          purposes, if immediately after such issue the total principal
          amount of unsecured indebtedness issued or assumed by Duquesne
          Light then outstanding would exceed 20% of the aggregate of (i)
          the total principal amount of all secured indebtedness then
          outstanding and (ii) the total of the capital stock and earned
          and capital surplus of Duquesne Light plus any premiums on
          capital stock of Duquesne Light as then to be stated on its books
          plus any premiums on capital stock of Duquesne Light of any class
          then carried on its books.  At December 31, 1995 Duquesne Light
          could have issued approximately $216 million of unsecured
          indebtedness (such as the Debentures) without violating this
          restriction.

          MANDATORY REDEMPTION

               If Duquesne Capital redeems MIPS of any series in accordance
          with the terms thereof, Duquesne Light shall redeem Debentures of
          the corresponding series, in a principal amount equal to the
          aggregate liquidation preference of the MIPS of such series so
          redeemed, at a redemption price equal to 100% of the aggregate
          principal amount of such Debentures to be redeemed, plus any
          accrued but unpaid interest, including Additional Interest, if
          any, any such redemption to be made on the date such MIPS are
          redeemed or on such earlier date as Duquesne Capital and Duquesne
          Light shall agree.

          OPTIONAL REDEMPTION

               Unless otherwise provided in a Prospectus Supplement,
          Duquesne Light will have the right to redeem the Debentures of
          any series at any time on or after the fifth anniversary of the
          last day of the month in which such Debentures are issued, in
          whole or in part, at a redemption price equal to 100% of the
          aggregate principal amount of such Debentures to be redeemed,
          plus any accrued but unpaid interest, including Additional
          Interest, if any, to the date fixed for redemption, upon not less
          than 30 nor more than 60 days' notice.

          INTEREST

               The Debentures relating to MIPS of any series will bear
          interest at the annual rate set forth in the Prospectus
          Supplement for such series, accruing from the date they are
          issued until maturity.  Such interest will be payable monthly in
          arrears on the last day of each calendar month to the holder of
          record one Business Day prior to the relevant interest payment
          date, subject to the right of Duquesne Light to extend any
          interest payment period as described below; provided, however,
          that if the Debentures of any series are held neither by Duquesne
          Capital nor by a securities depositary, Duquesne Light shall have
          the right to change such record dates.

               The amount of interest payable for any monthly interest
          payment period will be computed on the basis of twelve 30-day
          months and a 360-day year and, for any period shorter than a full
          monthly interest period, will be computed on the basis of the
          actual number of days elapsed in such period.

               In the event that any date on which interest or principal is
          payable on the Debentures is not a Business Day, then payment of
          the amounts payable on such date will be made on the next
          succeeding day which is a Business Day (and without any interest
          or other payment in respect of any such delay), except that, if
          such Business Day is in the next succeeding calendar year, such
          payment shall be made on the immediately preceding Business Day,
          in each case with the same force and effect, and in the same
          amount, as if made on such date.

          OPTION TO EXTEND INTEREST PAYMENT PERIOD

               Duquesne Light shall have the right at any time or times
          during the term of the Indenture Securities of any series,
          including any series of Debentures, so long as Duquesne Light is
          not in default in the payment of interest under any Indenture
          Securities, to extend interest payment periods for up to 60
          consecutive months, and at, or at any time prior to, the end of
          any such extended interest payment period Duquesne Light will pay
          all interest then accrued and unpaid (together with interest
          thereon at the rate specified for such Indenture Securities to
          the extent permitted by applicable law); provided that, during
          any such extended interest payment period, Duquesne Light shall
          not declare or pay any dividend on, or redeem, purchase, acquire
          or make a liquidation payment with respect to, any of its capital
          stock or make any guarantee payments with respect to the
          foregoing (other than payments under the Guarantee).  Prior to
          the end of any such extended interest payment period of less than
          60 consecutive months, Duquesne Light may further extend the
          interest payment period; provided that such extended interest
          payment period, together with all such further extensions
          thereof, may not exceed a period of 60 consecutive months. 
          Following the termination of any extended interest payment
          period, if Duquesne Light has paid all accrued and unpaid
          interest required by the Indenture Securities for such period,
          Duquesne Light shall have the right to again extend interest
          payment periods for up to 60 consecutive months as herein
          described.  So long as Duquesne Capital is the sole holder of
          Indenture Securities, Duquesne Light shall give Duquesne Capital
          notice of its selection of any such extended interest payment
          period one Business Day prior to the earlier of (i) the date
          dividends on any series of Preferred Securities would otherwise
          be payable and (ii) the date Duquesne Capital is required to give
          notice of the record or payment date of such dividends to any
          national securities exchange on which the Preferred Securities of
          such series shall be listed or to holders of the Preferred
          Securities of such series, but in any event not less than two
          Business Days prior to such record date.  Duquesne Light will
          cause Duquesne Capital to give such notice of Duquesne Light's
          selection of any such extended interest payment period to the
          holders of the Preferred Securities.  If Duquesne Capital is not
          the sole holder of the Indenture Securities, Duquesne Light shall
          give the holders of Indenture Securities (including the
          Debentures) notice of its selection of such extended interest
          payment period ten Business Days prior to the related interest
          payment date.

          ADDITIONAL INTEREST

               If Duquesne Capital shall be required to pay, with respect
          to its income derived from the interest payments on the Indenture
          Securities of any series, any amounts for or on account of any
          taxes, duties, assessments or governmental charges of whatever
          nature imposed by the United States, or any other taxing
          authority, then, in any such case, Duquesne Light will pay as
          interest on such series of Indenture Securities such additional
          interest ("Additional Interest") as may be necessary in order
          that the net amounts received and retained by Duquesne Capital
          after the payment of such taxes, duties, assessments or
          governmental charges shall result in Duquesne Capital's having
          such funds as it would have had in the absence of the payment of
          such taxes, duties, assessments or governmental charges.

          BOOK-ENTRY SYSTEM AND SETTLEMENT IN THE EVENT OF EXCHANGE

               In the event that Debentures are to be distributed to the
          holders of the MIPS, it is anticipated that such distribution
          would occur in book-entry form and that DTC, or any successor
          Depositary for the MIPS, would act as depositary for the
          Debentures and that the depositary arrangements for the
          Debentures would be substantially identical to those in effect
          for the MIPS.  For a description of DTC and the terms of the
          depositary arrangements relating to payments, transfers, voting
          rights, redemption and other notices and other matters, see
          "Description of the MIPS--Book-Entry-Only Issuance".

               Except under certain limited circumstances as described
          under "Description of the MIPS--Book-Entry-Only Issuance" for
          delivery of certificates evidencing beneficial ownership in MIPS,
          the Debentures would not be issuable as, or exchangeable for,
          Debentures in definitive certificated form.  In the event that
          Debentures were to be issued in certificated form, such
          Debentures would be in denominations of $25.00 and integral
          multiples thereof and principal and interest on such Debentures
          would be payable at, and transfers or exchanges of such
          Debentures would be effected at, the office or agency of Duquesne
          Light designated for such purposes.

          SUBORDINATION

               The Indenture will provide (and each holder of MIPS by
          acceptance thereof agrees) that each of the Debentures is
          subordinate and junior in right of payment to all Senior
          Indebtedness.  The Indenture defines "Senior Indebtedness" as all
          obligations (other than non-recourse obligations and the
          indebtedness issued under the Indenture) of, or guaranteed or
          assumed by, Duquesne Light for borrowed money (including both
          senior and subordinated indebtedness for borrowed money (other
          than the Indenture Securities)) or for the payment of money
          relating to any lease which is capitalized on the consolidated
          balance sheet of Duquesne Light and its subsidiaries in
          accordance with generally accepted accounting principles as in
          effect from time to time, or evidenced by bonds, debentures,
          notes or other similar instruments, and in each case, amendments,
          renewals, extensions, modifications and refundings of any such
          indebtedness or obligations, whether existing as of the date of
          the Indenture or subsequently incurred by Duquesne Light;
          provided that Duquesne Light's obligations under the Guarantee
          shall not be deemed to be "Senior Indebtedness" for purposes of
          the Indenture (or the Guarantee).  

               Upon the maturity of any Senior Indebtedness of Duquesne
          Light by lapse of time, acceleration or otherwise, all such
          Senior Indebtedness then due and owing shall first be paid in
          full, before any payment is made on account of, or Duquesne Light
          can acquire, any Indenture Securities (including the Debentures).

               In the event (a) of any insolvency or bankruptcy
          proceedings, or any receivership, liquidation, reorganization or
          other similar proceedings in respect of Duquesne Light or a
          substantial part of its property or of any proceedings for
          liquidation, dissolution or other winding up of Duquesne Light,
          whether or not involving insolvency or bankruptcy, or (b) that
          (i) a default shall have occurred with respect to the payment of
          principal of or interest on or other monetary amounts due and
          payable on any Senior Indebtedness or (ii) there shall have
          occurred a default (other than a default in the payment of
          principal or interest, or other monetary amounts due and payable)
          in respect of any Senior Indebtedness, as defined therein or in
          the instrument under which the same is outstanding, permitting
          the holder or holders thereof to accelerate the maturity thereof
          (with notice or lapse of time, or both), and such default shall
          have continued beyond the period of grace, if any, in respect
          thereof, and, in the cases of subclauses (i) and (ii) of this
          clause (b), such default shall not have been cured or waived or
          shall not have ceased to exist, or (c) that the principal of and
          the accrued interest on the Indenture Securities of any series
          shall have been declared due and payable upon an Event of Default
          and such declaration shall not have been rescinded and annulled
          as provided under the Indenture, then the holders of all Senior
          Indebtedness shall first be entitled to receive payment of the
          full amount due thereon, or provision shall be made for such
          payment in money or money's worth, before the holders of any of
          the Indenture Securities are entitled to receive a payment on
          account of the principal of or any interest on the indebtedness
          evidenced by their Indenture Securities.  Any payment or
          distribution, whether in cash, securities or other property,
          which would otherwise (but for the subordination provisions) be
          payable or deliverable in respect of the Indenture Securities
          shall be paid or delivered directly to the holders of such Senior
          Indebtedness (or their representative or trustee) in accordance
          with the priorities then existing among such holders until all
          Senior Indebtedness of Duquesne Light shall have been paid in
          full before any payment or distribution is made to the holders of
          Indenture Securities.  In the event that notwithstanding such
          subordination provisions, any payment or distribution of assets
          of any kind or character is made on the Indenture Securities
          before all Senior Indebtedness is paid in full, the Indenture
          Trustee or the holders of Indenture Securities receiving such
          payment will be required to pay over such payment or distribution
          to the holders of such Senior Indebtedness.

               No present or future holder of any Senior Indebtedness of
          Duquesne Light shall be prejudiced in the right to enforce
          subordination of the indebtedness under the Indenture by any act
          or failure to act on the part of Duquesne Light.

               Senior Indebtedness will not be deemed to have been paid in
          full unless the holders thereof shall have received cash (or
          securities or other property satisfactory to such holders) in
          full payment of such Senior Indebtedness then outstanding.  Upon
          the payment in full of all Senior Indebtedness, the holders of
          Indenture Securities shall be subrogated to all the rights of any
          holders of such Senior Indebtedness to receive any further
          payments or distributions of cash, property or securities of
          Duquesne Light applicable to such Senior Indebtedness until the
          Indenture Securities shall have been paid in full, and such
          payments or distributions of cash, property or securities
          received by the holders of Indenture Securities, by reason of
          such subrogation, which otherwise would be paid or distributed to
          the holders of such Senior Indebtedness, shall, as between
          Duquesne Light and its creditors other than the holders of Senior
          Indebtedness, on the one hand, and the holders of Indenture
          Securities on the other, be deemed to be a payment on account of
          Senior Indebtedness, and not on account of the Indenture
          Securities.

          CERTAIN COVENANTS OF DUQUESNE LIGHT

               The Indenture will provide that, so long as any Preferred
          Securities of any series remain outstanding, Duquesne Light will
          not declare or pay any dividend on, or redeem, purchase, acquire
          or make a liquidation payment with respect to, any of its capital
          stock or make any guarantee payments with respect to the
          foregoing (other than payments under the Guarantee) if at such
          time (i) Duquesne Light will be in default with respect to its
          payment or other obligations under the Guarantee, (ii) there has
          occurred and is continuing a payment default (whether before or
          after the expiration of any period of grace) or an Event of
          Default under the Indenture or (iii) Duquesne Light has given
          notice of its election to extend any interest payment period as
          provided in the Indenture, and such period, or any extension
          thereof, shall be continuing. 

               The Indenture will also provide that, so long as Preferred
          Securities of any series remain outstanding, Duquesne Light will
          (i) maintain direct or indirect ownership of all interests in
          Duquesne Capital other than such Preferred Securities, (ii) not
          voluntarily (to the extent permitted by law) dissolve, liquidate
          or wind up Duquesne Capital, (iii) remain the sole General
          Partner of Duquesne Capital and timely perform in all material
          respects all of its duties as the General Partner of Duquesne
          Capital (including the duty to pay dividends on the MIPS as
          described in the fourth paragraph under "Description of the
          MIPS--Dividends"), provided that any permitted successor to
          Duquesne Light under the Indenture may succeed to Duquesne
          Light's duties as General Partner of Duquesne Capital, and (iv)
          use reasonable efforts to cause Duquesne Capital to remain a
          limited partnership and otherwise continue to be treated as a
          partnership for Federal income tax purposes; provided that
          Duquesne Light may permit Duquesne Capital to consolidate or
          merge with or into another limited partnership or other permitted
          successor as described above under "Description of the
          MIPS--Merger, Consolidation, Amalgamation, etc. of Duquesne
          Capital" so long as Duquesne Light  agrees to comply with the
          covenants described in clauses (i) through (iv) above with
          respect to such successor limited partnership or other permitted
          successor.

               So long as Duquesne Capital holds the Debentures of any
          series, it may not waive compliance or waive any default in
          compliance by Duquesne Light with any covenant or other term in
          such Debentures or the Indenture, or any past default under the
          Indenture, without the approval or consent of the holders of at
          least 66 2/3% in aggregate liquidation preference of the
          outstanding Preferred Securities affected.  

          EVENTS OF DEFAULT; REMEDIES

               The following events shall constitute Events of Default with
          respect to each series of Indenture Securities (including each
          series of Debentures) issued under the Indenture:

                    (a)  Duquesne Light shall fail to pay any interest,
               including any Additional Interest, on any Indenture
               Securities of such series within 30 days after the same
               becomes due and payable (whether or not payment is
               prohibited by the provisions described above under
               "Subordination" or otherwise); provided that a valid
               extension of the interest payment period by Duquesne Light
               shall not constitute a failure to pay interest for this
               purpose;

                    (b)  Duquesne Light shall fail to pay when due any
               principal of or premium, if any, on any Indenture Securities
               of such series, whether at maturity, upon redemption, by
               declaration of acceleration or otherwise (whether or not
               payment is prohibited by the provisions described above
               under "Subordination" or otherwise);

                    (c)  Duquesne Light shall fail to perform or breach any
               covenant or warranty in the Indenture (other than a covenant
               or warranty a default in the performance of which or breach
               of which is dealt with elsewhere under this paragraph) for a
               period of 60 days after there has been given to Duquesne
               Light by the Indenture Trustee, or to Duquesne Light and the
               Indenture Trustee by the holders of at least 25% in
               principal amount of outstanding Indenture Securities of such
               series, a written notice specifying such default or breach
               and requiring it to be remedied and stating that such notice
               is a "Notice of Default", unless the Indenture Trustee, or
               the Indenture Trustee and the holders of a principal amount
               of Indenture Securities of such series not less than the
               principal amount of Indenture Securities of such series the
               holders of which gave such notice, as the case may be, agree
               in writing to an extension of such period prior to its
               expiration; provided, however, that the Indenture Trustee,
               or the Indenture Trustee and such holders, as the case may
               be, will be deemed to have agreed to an extension of such
               period if corrective action has been initiated by Duquesne
               Light within such period and is being diligently pursued;

                    (d)  Certain events relating to reorganization,
               bankruptcy or insolvency of Duquesne Capital or Duquesne
               Light or the appointment of a receiver or trustee for its
               property; or

                    (e)  any other Event of Default specified with respect
               to Indenture Securities of such series.

          No Event of Default with respect to any series of Indenture
          Securities (other than that described in (d) above) necessarily
          constitutes an Event of Default with respect to the Indenture
          Securities of any other series issued under the Indenture.

               If an Event of Default due to the default in payment of
          principal of or interest on any series of Indenture Securities or
          due to the default in the performance or breach of any other
          covenant or warranty of Duquesne Light applicable to the
          Indenture Securities of such series but not applicable to all
          series occurs and is continuing, then either the Indenture
          Trustee or the holders of 25% in principal amount of the
          outstanding Indenture Securities of such series or a Special
          Representative appointed in respect of the Preferred Securities
          of the corresponding series as described under "Description of
          the MIPS--Voting Rights" may declare the principal of all of the
          Indenture Securities of such series and interest accrued thereon
          to be due and payable immediately (subject to the subordination
          provisions of the Indenture).  If an Event of Default due to the
          default in the performance of any other covenants or agreements
          in the Indenture applicable to all outstanding Indenture
          Securities or due to certain events of bankruptcy, insolvency or
          reorganization of Duquesne Light or Duquesne Capital has occurred
          and is continuing, either the Indenture Trustee or the holders of
          not less than 25% in principal amount of all outstanding
          Indenture Securities, considered as one class, or the Special
          Representative or Special Representatives appointed in respect of
          series of outstanding Indenture Securities representing not less
          than 25% in principal amount of all Indenture Securities then
          outstanding, and not the holders of the Indenture Securities of
          any one of such series or the Special Representative appointed in
          respect of any one series, may make such declaration of
          acceleration (subject to the subordination provisions of the
          Indenture).

               At any time after the declaration of acceleration with
          respect to the Indenture Securities of any series has been made
          and before a judgment or decree for payment of the money due has
          been obtained, the Event or Events of Default giving rise to such
          declaration of acceleration will, without further act, be deemed
          to have been waived, and such declaration and its consequences
          will, without further act, be deemed to have been rescinded and
          annulled, if (a) Duquesne Light has paid or deposited with the
          Indenture Trustee a sum sufficient to pay (1) all overdue
          interest on all Indenture Securities of such series; (2) the
          principal of and premium, if any, on any Indenture Securities of
          such series which have become due otherwise than by such
          declaration of acceleration and interest thereon at the rate or
          rates prescribed therefor in such Indenture Securities; (3)
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Indenture Securities to the extent that payment
          of such interest is lawful; and (4) all amounts due to the
          Indenture Trustee under the Indenture; and (b) any other Event or
          Events of Default with respect to the Indenture Securities of
          such series, other than the nonpayment of the principal of the
          Indenture Securities of such series which has become due solely
          by such declaration of acceleration, have been cured or waived as
          provided in the Indenture.

               If an Event of Default with respect to the Indenture
          Securities of any series occurs and is continuing, the holders of
          a majority in principal amount of the outstanding Indenture
          Securities of such series or the Special Representative appointed
          in respect of such series may direct the time, method and place
          of conducting any proceeding for any remedy available to the
          Indenture Trustee or exercising any trust or power conferred on
          the Indenture Trustee with respect to the Indenture Securities of
          such series; provided, however, that if an Event of Default
          occurs and is continuing with respect to more than one series of
          Indenture Securities, the holders of a majority in aggregate
          principal amount of the outstanding Indenture Securities of all
          such series, considered as one class, or the Special
          Representative or Special Representatives appointed with respect
          to series of outstanding Indenture Securities representing 66 2/3% 
          in aggregate principal amount of the outstanding Indenture 
          Securities of all such series, will have the right to make such 
          direction, and not the holders of the Indenture Securities of any 
          one of such series or the Special Representative of any one of 
          such series; and provided, further, that such direction will not 
          be in conflict with any rule of law or with the Indenture.  Before 
          proceeding to exercise any right or power under the Indenture at 
          the direction of such holders or any such Special Representative, 
          the Indenture Trustee shall be entitled to receive from such holders 
          or any such Special Representative reasonable security or indemnity 
          against the costs, expenses and liabilities which might be incurred 
          by it in compliance with any such direction.  

               Duquesne Light will be required to furnish to the Indenture
          Trustee annually a statement of an officer of Duquesne Light to
          the effect that, to the best of such officer's knowledge,
          Duquesne Light is not in default in the performance of the terms
          of the Indenture or, if such officer has knowledge that Duquesne
          Light is in default, specifying such default.  

               The Indenture provides that no holder of Indenture
          Securities issued under the Indenture may institute any
          proceeding against Duquesne Light with respect to the Indenture
          unless (a) the holder has previously given to the Indenture
          Trustee written notice of a continuing Event of Default and
          unless the holders of not less than 25% in principal amount of
          the Indenture Securities of all series of Indenture Securities in
          respect of which an Event of Default has occurred and is
          continuing (considered as one class) have requested the Indenture
          Trustee to institute such action and shall have offered the
          Indenture Trustee reasonable indemnity, (b) the Indenture Trustee
          shall not have instituted such action within 60 days of such
          request, and (c) the Indenture Trustee shall not have received
          direction inconsistent with such written request by the holders
          of a majority in principal amount of the outstanding Indenture
          Securities of such affected series (considered as one class).
          Furthermore, no holder will be entitled to institute any such
          action if and to the extent that such action would disturb or
          prejudice the rights of other holders of Indenture Securities. 
          Notwithstanding the foregoing, each holder of an Indenture
          Security has a right, which is absolute and unconditional, to
          receive payment of the principal of and premium, if any, and
          interest, subject to the right of Duquesne Light to extend
          interest payment periods in accordance with the Indenture, if
          any, on such Indenture Security when due and to institute suit
          for the enforcement of any such payment, and such rights may not
          be impaired without the consent of such holder.

               The Indenture requires the Indenture Trustee to give to all
          holders of outstanding Indenture Securities of any series notice
          of any default to the extent required by the Trust Indenture Act
          of 1939, as amended (the "Trust Indenture Act"), unless such
          default has been cured or waived; provided that in the case of
          any default of the character specified above in clause (c) under
          "Events of Default", no such notice will be given to such holders
          until at least 45 days after the occurrence thereof.  The Trust
          Indenture Act currently permits the Indenture Trustee to withhold
          notices of default (except for certain payment defaults) if the
          Indenture Trustee in good faith determines the withholding of
          such notice to be in the interests of the holders.

          ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF MIPS

               Holders of MIPS will have the rights referred to under
          "Description of the MIPS--Voting Rights", including the right under
          certain circumstances to appoint a Special Representative, which
          Special Representative shall be authorized to exercise Duquesne
          Capital's right to accelerate the principal amount of the
          Debentures and to enforce Duquesne Capital's other rights under
          the Debentures and the Indenture.

               The Indenture provides that for so long as any Preferred
          Securities remain outstanding, the obligations of Duquesne Light
          thereunder are for the benefit of the holders of Preferred
          Securities.  The holders may, to the fullest extent permitted by
          applicable law, enforce Duquesne Light's obligations under the
          Indenture and the Debentures directly against Duquesne Light to
          the same extent as if such holders of Preferred Securities held a
          principal amount of Debentures equal to the liquidation
          preference of the Preferred Securities held by such holders.

          MODIFICATION OF INDENTURE

               Without the consent of any holders of Indenture Securities,
          Duquesne Light and the Indenture Trustee may enter into one or
          more supplemental indentures for any of the following purposes:
          (a) to evidence the assumption by any successor to Duquesne Light
          of the covenants of Duquesne Light in the Indenture and the
          Indenture Securities; or (b) to add one or more covenants of
          Duquesne Light or other provisions for the benefit of the holders
          of all or any series of outstanding Indenture Securities or to
          surrender any right or power conferred upon Duquesne Light by the
          Indenture; or (c) to add any additional Events of Default with
          respect to all or any series of outstanding Indenture Securities;
          or (d) to change or eliminate any provision of the Indenture or
          to add any new provision to the Indenture, provided that if such
          change, elimination or addition will adversely affect the
          interests of the holders of Indenture Securities of any series in
          any material respect, such change, elimination or addition will
          become effective with respect to such series only when there is
          no Indenture Security of such series remaining outstanding under
          the Indenture; or (e) to provide collateral security for the
          Indenture Securities; or (f) to establish the form or terms of
          Indenture Securities of any series as permitted by the Indenture;
          or (g) to evidence and provide for the acceptance of appointment
          of a successor Indenture Trustee under the Indenture with respect
          to the Indenture Securities of one or more series and to add to
          or change any of the provisions of the Indenture as shall be
          necessary to provide for or to facilitate the administration of
          the trusts under the Indenture by more than one trustee; or (h) 
          to provide for the procedures required to permit the utilization
          of a noncertificated system of registration for any series of
          Indenture Securities; or (i) to change any place where (1) the
          principal of and premium, if any, and interest, if any, on any
          Indenture Securities shall be payable, (2) any Indenture
          Securities may be surrendered for registration of transfer or
          exchange and (3) notices and demands to or upon Duquesne Light in
          respect of Indenture Securities and the Indenture may be served;
          or (j) to cure any ambiguity or inconsistency or to make or
          change any other provisions with respect to matters and questions
          arising under the Indenture, provided such changes or additions
          shall not adversely affect the interests of the holders of
          Indenture Securities of any series in any material respect. 

               Without limiting the generality of the foregoing, if the
          Trust Indenture Act is amended after the date of the original
          Indenture in such a way as to require changes to the Indenture or
          the incorporation therein of additional provisions or so as to
          permit changes to, or the elimination of, provisions which, at
          the date of the original Indenture or at any time thereafter,
          were required by the Trust Indenture Act to be contained in the
          Indenture, Duquesne Light and the Indenture Trustee may, without
          the consent of any holders, enter into one or more supplemental
          indentures to effect or reflect any such amendment. 

               The consent of the holders of not less than a majority in
          aggregate principal amount of the Indenture Securities of all
          series then outstanding under the Indenture, considered as one
          class, is required for the purpose, pursuant to an indenture or
          supplemental indenture, of adding any provisions to, or changing
          in any manner or eliminating any of the provisions of, the
          Indenture or modifying in any manner the rights of the holders of
          such series; provided, however, that if less than all of the
          series of Indenture Securities outstanding under the Indenture
          are directly affected by a supplemental indenture, then the
          consent only of the holders of a majority in aggregate principal
          amount of the outstanding Indenture Securities of all series so
          directly affected, considered as one class, will be required; and
          provided, further, that no such supplemental indenture will,
          without the consent of the holder of each Indenture Security
          outstanding under the Indenture of each such series directly
          affected thereby, (a) change the stated maturity of, or any
          installment of principal of or the rate of interest on or method
          of calculating the rate of interest on (or the amount of any
          installment of interest on), any Indenture Security, or reduce
          the principal thereof or redemption premium thereon, if any, or
          change the currency in which any Indenture Security is payable,
          or impair the right to institute suit for the enforcement of
          payment on any Indenture Security, (b) reduce the percentage in
          principal amount of the Indenture Securities outstanding under
          such series (or, if applicable, in liquidation preference of any
          series of Preferred Securities) required to consent to any
          supplemental indenture or waiver under the Indenture or to reduce
          the requirements for quorum and voting or (c) modify the
          provisions in the Indenture relating to supplemental indentures,
          waivers of certain covenants and waivers of past defaults. 

               A supplemental indenture which changes or eliminates any
          covenant or other provision of the Indenture which has expressly
          been included solely for the benefit of one or more particular
          series of Indenture Securities, or which modifies the rights of
          the holders of Indenture Securities of such series with respect
          to such covenant or other provision, shall be deemed not to
          affect the rights under the Indenture of the holders of any other
          Indenture Securities.

               Notwithstanding the foregoing, so long as any of the
          Preferred Securities remain outstanding, Duquesne Capital shall
          not agree to any such amendment that affects the holders of
          Preferred Securities then outstanding, without the prior consent
          of the holders of not less than 66 2/3% in aggregate liquidation 
          preference of all such affected Preferred Securities outstanding 
          considered as one class (or, in the case of changes described in 
          (a), (b) or (c) above, 100% in aggregate liquidation preference of 
          all such affected Preferred Securities then outstanding considered 
          as one class).

          DEFEASANCE

               The Indenture Securities of any series, or any portion of
          the principal amount thereof, will be deemed to have been paid
          for purposes of the Indenture, and the entire indebtedness of
          Duquesne Light in respect thereof will be deemed to have been
          satisfied and discharged, if there shall have been irrevocably
          deposited with the Indenture Trustee or any paying agent other
          than Duquesne Light, in trust:  (a) money in the amount which
          will be sufficient, or (b) Government Obligations (as defined
          below), which do not contain provisions permitting the redemption
          or other prepayment thereof at the option of the issuer thereof,
          the principal of and the interest on which when due, without any
          regard to reinvestment thereof, will provide monies which,
          together with the money, if any, deposited with or held by the
          Indenture Trustee, will be sufficient, or (c) a combination of
          (a) and (b) which will be sufficient, to pay when due the
          principal of and premium, if any, and interest, if any, due and
          to become due on such Indenture Securities or portions thereof on
          and prior to the maturity thereof.  For this purpose, Government
          Obligations include direct obligations of, or obligations
          unconditionally guaranteed by, the United States of America
          entitled to the benefit of the full faith and credit thereof and
          certificates, depositary receipts or other instruments which
          evidence a direct ownership interest in such obligations or in
          any specific interest or principal payments due in respect
          thereof.

          GOVERNING LAW

               The Indenture and Debentures will be governed by and
          construed in accordance with the laws of the State of New York,
          except to the extent that the laws of any other jurisdiction
          shall be mandatorily applicable.

          MISCELLANEOUS

               The Indenture provides that Duquesne Light may consolidate
          or merge with, or convey, transfer or lease its properties and
          assets substantially as an entirety to any other corporation,
          provided that such successor corporation expressly assumes all
          obligations of Duquesne Light under the Indenture and certain
          other conditions are met.

          RESIGNATION OF THE INDENTURE TRUSTEE

               The Indenture Trustee may resign at any time by giving
          written notice thereof to Duquesne Light or may be removed at any
          time by act of the holders of a majority in aggregate principal
          amount of Indenture Securities then outstanding delivered to the
          Indenture Trustee and Duquesne Light; provided that so long as
          any Preferred Securities remain outstanding, Duquesne Capital
          shall not enter into any act to remove the Indenture Trustee
          without the consent of the holders of 66 2/3% in aggregate
          liquidation preference of Preferred Securities outstanding.  No
          resignation or removal of the Indenture Trustee and no
          appointment of a successor trustee will become effective until
          the acceptance of appointment by a successor trustee in
          accordance with the requirements of the Indenture.  So long as no
          Event of Default or event which, after notice or lapse of time,
          or both, would become an Event of Default has occurred and is
          continuing, if Duquesne Light has delivered to the Indenture
          Trustee a resolution of its Board of Directors appointing a
          successor trustee and such successor has accepted such
          appointment in accordance with the terms of the Indenture, the
          Indenture Trustee will be deemed to have resigned and the
          successor will be deemed to have been appointed as trustee in
          accordance with the Indenture.

                            UNITED STATES INCOME TAXATION

          IN GENERAL

               This section is a summary of certain Federal income tax
          considerations that may be relevant to prospective purchasers of
          MIPS and represents the opinion of Reid & Priest LLP, counsel to
          Duquesne Light and Duquesne Capital, insofar as it relates to
          matters of law and legal conclusions.  This section is based upon
          current provisions of the Internal Revenue Code of 1986, as
          amended (the "Code"), existing and proposed regulations
          thereunder and current administrative rulings and court
          decisions, all of which are subject to change.  Subsequent
          changes may cause tax consequences to vary substantially from the
          consequences described below.

               No attempt has been made in the following discussion to
          comment on all Federal income tax matters affecting purchasers of
          MIPS.  Moreover, the discussion focuses on holders of MIPS who
          are individual citizens or residents of the United States and has
          only limited application to corporations, estates, trusts or non-
          resident aliens.  In addition, this discussion does not address
          the tax consequences to persons who purchase MIPS other than
          pursuant to their initial issuance and distribution. 
          Accordingly, each prospective purchaser of MIPS should consult,
          and should depend upon, his or her own tax advisor in analyzing
          the Federal, state, local and foreign income tax consequences of
          the purchase, ownership, or disposition of MIPS.

          INCOME FROM MIPS

               In the opinion of Reid & Priest LLP, Duquesne Capital will
          be treated as a partnership for Federal income tax purposes. 
          Accordingly, each MIPS holder will be required to include in
          gross income his or her distributive share of Duquesne Capital's
          net income.  Any amount so included in a MIPS holder's gross
          income will increase his or her tax basis in the MIPS, and the
          amount of cash distributed to the MIPS holder will be a non-
          taxable reduction in his or her tax basis in the MIPS.  The
          income included in a MIPS holder's gross income should not exceed
          cash received on such MIPS, except in the limited circumstances
          described below under "Potential Extension of Interest Payment
          Period."  No portion of such income will be eligible for the
          dividends received deduction.

          DISPOSITION OF MIPS

               Upon the sale or redemption for cash of MIPS, gain or loss
          will be recognized by each MIPS holder in an amount equal to the
          difference between (i) the amount realized by the MIPS holder for
          such MIPS, and (ii) such holder's tax basis in such MIPS. 
          Depending upon the particular circumstances of a MIPS holder,
          gain or loss recognized by such holder on the sale or exchange of
          MIPS held for more than one (1) year will generally be taxable as
          long-term capital gain or loss.

          EXCHANGE OF THE MIPS FOR DEBENTURES

               Under certain circumstances, as described under the caption
          "Description of the MIPS--Special Event Redemption or Exchange",
          Duquesne Capital may distribute the Debentures to MIPS holders in
          exchange for the MIPS.  Such an exchange will generally be
          treated as a non-taxable exchange and will result in each MIPS
          holder receiving an aggregate basis in its Debentures equal to
          such holder's aggregate tax basis in its MIPS.  A MIPS holder's
          holding period in the Debentures received in such an exchange
          will include the period for which the MIPS were held by such
          holder, provided the MIPS were held as a capital asset.

               If such an exchange occurs following a determination that,
          due to a change in law, Duquesne Capital is subject to Federal
          income tax with respect to interest received on the Debentures,
          such  exchange will generally be taxable to the MIPS holder. 
          Gain or loss will be recognized in amount measured by the
          difference between the MIPS holder's basis in its MIPS and the
          value of the Debentures received in the exchange.  In such a
          case, the holding period of the MIPS holder for the Debentures
          will not include the period for which the MIPS were held.

          POTENTIAL EXTENSION OF INTEREST PAYMENT PERIOD

               Under the terms of the Debentures, Duquesne Light will be
          permitted to extend from time to time interest payment periods
          for up to 60 consecutive months.  Because the interest payment
          period is extendable, the Debentures will be treated as issued
          with "original issue discount" ("OID") pursuant to Code sections
          1271 et seq. and the Treasury Regulations promulgated thereunder. 
          Pursuant thereto, Duquesne Capital will be required to include
          the interest on the Debentures in income as it accrues in
          accordance with a constant yield method before actual receipt of
          the cash payment representing interest.

               Accrued income includible by Duquesne Capital during an
          extended interest payment period pursuant to the OID rules will
          be allocated, but not distributed, to MIPS holders of record on
          the Business Day preceding the last day of each calendar month. 
          As a result, during an extended interest payment period holders
          of MIPS will include interest in gross income in advance of the
          receipt of cash.  The tax basis of MIPS will be increased by the
          amount of any interest that is included in a MIPS holder's income
          without receipt of cash, and will be decreased when and if such
          cash is subsequently received by such MIPS holder from Duquesne
          Capital.

               However, in the event that interest payable on the
          Debentures is not deductible by Duquesne Light for Federal income
          tax purposes, during an extended interest payment period holders
          of the MIPS will not include any amount in gross income with
          respect to the MIPS until Duquesne Capital is required to include
          such amounts in its income, which should occur at approximately
          the same time as the receipt of cash from Duquesne Capital.  

          UNITED STATES ALIEN HOLDERS

               For purposes of this discussion, a "United States Alien
          Holder" is any holder of MIPS who is (i) a nonresident alien
          individual, foreign corporation, partnership, estate or trust,
          and (ii) not subject to Federal income tax on a net income basis
          in respect of such MIPS.

               Under current Federal income tax law:

                    (i) payments by Duquesne Capital or any of its paying
               agents to any United States Alien Holder will not be subject
               to Federal withholding tax provided that (a) the beneficial
               owner of MIPS does not actually or constructively own ten
               percent (10%) or more of the total combined voting power of
               all classes of stock of Duquesne Light entitled to vote, (b)
               the beneficial owner of MIPS is not a controlled foreign
               corporation that is related to Duquesne Light through stock
               ownership, and (c) either (1) the beneficial owner of MIPS
               certifies to Duquesne Capital or its agent, under penalties
               of perjury, that it is a United States Alien Holder and
               provides its name and address, or (2) the holder of MIPS is
               a securities clearing organization, bank or other financial
               institution that holds customers' securities in the ordinary
               course of its trade or business (a "Financial Institution")
               and such holder certifies to Duquesne Capital or its agent
               under penalties of perjury that such statement has been
               received from the beneficial owner by it or by a Financial
               Institution between it and the beneficial owner and
               furnishes Duquesne Capital or its agent with a copy thereof;
               and

                    (ii) a United States Alien Holder will generally not be
               subject to Federal tax on any gain realized upon the sale or
               exchange of MIPS unless such holder is present in the United
               States for 183 days or more in the taxable year of the sale
               and either has a "tax home" in the United States or certain
               other requirements are met.

          The above paragraphs (i) and (ii) are subject to the following
          discussion on backup withholding and assume satisfaction by
          Duquesne Light of its withholding tax obligations.

          DUQUESNE CAPITAL INFORMATION RETURNS AND AUDIT PROCEDURES

               Duquesne Light, as the general partner of Duquesne Capital,
          will furnish each MIPS holder with a Schedule K-1 for each year
          setting forth such MIPS holder's allocable share of income for
          the prior calendar year.  Duquesne Light is currently required to
          furnish such Schedule K-1's as soon as practicable following the
          end of each year, but in any event prior to March 31.

               Any person who holds MIPS as a nominee for another person is
          required to furnish to Duquesne Light: (i) the name, address and
          taxpayer identification number of the beneficial owner and
          nominee; (ii) information as to whether the beneficial owner is
          (a) a person that is not a United States person, (b) a foreign
          government, an international organization or any wholly-owned
          agency or instrumentality of the foregoing, or (c) a tax-exempt
          entity; (iii) the amount and description of the MIPS held,
          acquired or transferred for the beneficial owner; and (iv)
          certain information including the dates of acquisitions and
          transfers, means of acquisitions and transfers, and acquisition
          costs for purchases, as well as the amount of net proceeds from
          sales.  Brokers and financial institutions are required to
          furnish additional information, including whether they are United
          States persons, and certain information on MIPS that they
          acquire, hold, or transfer for their own accounts.  A penalty of
          $50 per failure (up to a maximum of $100,000 per calendar year)
          is imposed by the Code for failure to report such information to
          Duquesne Light.  The nominee is required to supply the beneficial
          owners of the MIPS with the information furnished to Duquesne
          Light.

          BACKUP WITHHOLDING AND INFORMATION REPORTING

               In general, information reporting requirements will apply to
          payments of the proceeds of the sale of MIPS within the United
          States to noncorporate U.S. holders of MIPS, and "backup
          withholding" at a rate of thirty-one percent (31%) will apply to
          such payments if such holder fails to provide to Duquesne Capital
          an accurate taxpayer identification number or fails to report in
          full dividend and interest income.

               Payments of the proceeds from the sale by a United States
          Alien Holder of MIPS made to or through a foreign office or a
          broker will not be subject to information reporting or backup
          withholding. However, if the broker is a United States person, a
          controlled foreign corporation for United States tax purposes, or
          a foreign person fifty percent (50%) or more of whose gross
          income is effectively connected with a United States trade or
          business for a specified three (3) year period, information
          reporting may apply to such payments.  Payments of the proceeds
          from the sale of MIPS to or through the United States office of a
          broker is subject to information reporting and backup withholding
          unless the holder or beneficial owner certifies as to its United
          States Alien Holder status or otherwise establishes an exemption
          from information reporting and backup withholding.

          POSSIBLE TAX LAW CHANGES

               On March 19, 1996, the Revenue Reconciliation Bill of 1996
          (the "Bill"), the revenue portion of President Clinton's budget
          proposal, was released.  The Bill would, among other things,
          generally deny interest deductions for interest on an instrument
          issued by a corporation that has a maximum weighted average
          maturity of more than 40 years.  The Bill would also generally
          treat as equity an instrument issued by a corporation that has a
          maximum term of 20 years and that is not shown as indebtedness on
          the separate balance sheet of the issuer or, where the instrument
          is issued to a related party (other than a corporation), where
          the holder or some other related party issues a related
          instrument that is not shown as indebtedness on the issuer's
          balance sheet.  The above-described provisions were proposed to
          be effective generally for instruments issued on or after
          December 7, 1995.  If either provision were to apply to the
          Debentures, Duquesne Light would be unable to deduct interest on
          the Debentures.  However, on March 29, 1996, the Chairmen of the
          Senate Finance and House Ways and Means Committees issued a joint
          statement to the effect that it was their intention that the
          effective date of the President's legislative proposals, if
          adopted, will be no earlier than the date of appropriate
          Congressional action.  There can be no assurance, however, that
          current or future legislative proposals or final legislation will
          not affect the ability of Duquesne Light to deduct interest on
          the Debentures.  Such a change would constitute a Tax Event,
          which would permit Duquesne Light to cause a redemption of the
          MIPS or a distribution of such Debentures in liquidation of
          Duquesne Capital, as described more fully under "Description of
          the MIPS--Special Event Redemption or Exchange" above.

                                 PLAN OF DISTRIBUTION

               Duquesne Capital may sell MIPS (i) through underwriters,
          including Goldman, Sachs & Co., (ii) through dealers, (iii)
          through agents or (iv) directly to purchasers.  The Prospectus
          Supplement relating to the MIPS of any series will set forth the
          terms of such offering, including the names of any underwriters,
          dealers or agents involved in the sale of such MIPS, the number
          of MIPS of such series to be purchased by any underwriters,
          dealers or agents and any applicable commissions or discounts. 
          The net estimated proceeds to Duquesne Capital from such series
          of MIPS will also be set forth in the Prospectus Supplement.

               If underwriters are used in the sale, the MIPS being sold
          will be acquired by the underwriters for their own account and
          may be resold from time to time in one or more transactions,
          including negotiated transactions, at a fixed public offering
          price or at varying prices determined at the time of sale. 
          Unless otherwise set forth in the Prospectus Supplement relating
          to the MIPS of any series, the obligations of the underwriters to
          purchase such MIPS will be subject to certain conditions
          precedent and the underwriters will be obliged to purchase all of
          such MIPS if any of such MIPS are purchased.  Any initial public
          offering price and any discounts or concessions allowed or
          reallowed or paid to dealers may be changed from time to time.

               If dealers are used in the sale, unless otherwise indicated
          in the Prospectus Supplement relating to the MIPS of any series,
          Duquesne Capital will sell such MIPS to the dealers as
          principals.  The dealers may then resell such MIPS to the public
          at varying prices to be determined by such dealers at the time of
          resale.

               MIPS of any series may also be sold through agents
          designated by Duquesne Capital from time to time or directly by
          Duquesne Capital.  Any agent involved in the offering and sale of
          any such MIPS will be named, and any commissions payable by
          Duquesne Capital to such agent will be set forth, in the
          Prospectus Supplement relating to the MIPS of such series. 
          Unless otherwise indicated in such Prospectus Supplement, any
          such agent will act on a reasonable efforts basis for the period
          of its appointment.

               Underwriters, dealers and agents may be entitled under
          agreements entered into with Duquesne Light or Duquesne Capital
          to indemnification by Duquesne Light or Duquesne Capital against
          certain civil liabilities, including liabilities under the
          Securities Act, or to contribution with respect to payments which
          the underwriters, dealers or agents may be required to make in
          respect thereof.  Underwriters, dealers and agents may be
          customers of, engage in transactions with, or perform services
          for, Duquesne Light and Duquesne Capital in the ordinary course
          of business.

               Each series of MIPS will be a new issue of securities and
          will have no established trading market.  Any underwriter to whom
          MIPS of any series are sold by Duquesne Capital for public
          offering and sale may make a market in such series of MIPS, but
          such underwriters will not be obligated to do so and may
          discontinue any market making at any time without notice.  If so
          indicated in the accompanying Prospectus Supplement for any
          series of MIPS, the MIPS of such series will be listed on a
          national securities exchange.  No assurance can be given as to
          the liquidity of, or the trading markets for, any MIPS.
