                                OFFICER'S CERTIFICATE


               ________________, the _________ of Delmarva Power & Light
          Company (the "Company"), pursuant to the authority granted in the
          Board Resolutions of the Company dated _____________, 1996, and
          Sections 201 and 301 of the Indenture defined herein, does hereby
          certify to Wilmington Trust Company (the "Trustee"), as Trustee
          under the Indenture of the Company (For Unsecured Subordinated
          Debt Securities relating to Trust Securities) dated as of
          ______________, 1996 (the "Indenture") that:

              
               1.   The securities of the first series to be issued under
                    the Indenture shall be designated "____% Junior
                    Subordinated Debentures, Series I, Due" (the
                    "Debentures of the First Series").  The Debentures of
                    the First Series are to be issued to Delmarva Power
                    Financing I, a Delaware statutory business trust (the
                    "Trust");
         

               2.   The Debentures of the First Series shall be limited in
                    aggregate principal amount to $_____________ at any
                    time Outstanding, except as contemplated in Section
                    301(b) of the Indenture;

               3.   The Debentures of the First Series shall mature and the
                    principal shall be due and payable together with all
                    accrued and unpaid interest thereon on ____________,
                    ____;

        
               4.   The Debentures of the First Series shall bear interest
                    from, and including, the date of original issuance, at
                    the rate of ____% per annum payable quarterly in
                    arrears (together with Additional Interest, if any) on
                    March 31, June 30, September 30 and December 31 of each
                    year (each, an "Interest Payment Date") commencing
                    ___________, 1996.  The amount of interest payable for
                    any such period will be computed on the basis of a 360-
                    day year of twelve 30-day months and for any period
                    shorter than a full month, on the basis of the actual
                    number of days elapsed in such period.  Interest on the
                    Debentures of the First Series will accrue from, and
                    including, the date of original issuance and will
                    accrue to, and including, the first Interest Payment
                    Date, and for each subsequent Interest Payment Date
                    will accrue from, and excluding, the last Interest
                    Payment Date through which interest has been paid or
                    duly provided for to, and including, such Interest
                    Payment Date. In the event that any Interest Payment
                    Date is not a Business Day, then payment of interest
                    payable on such date will be made on the next
                    succeeding day which is a Business Day, 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 as if made on such Interest Payment
                    Date;
                         

               5.   Each installment of interest on a Debenture of the
                    First Series shall be payable to the Person in whose
                    name such Debenture of the First Series is registered
                    at the close of business on the Business Day 15 days
                    preceding the corresponding Interest Payment Date (the
                    "Regular Record Date") for the Debentures of the First
                    Series; provided, however, that if the Debentures of
                    the First Series are held neither by the Trust nor by a
                    securities depositary, the Company shall have the right
                    to change the Regular Record Date by one or more
                    Officer's Certificates.  Any installment of interest on
                    the Debentures of the First Series not punctually paid
                    or duly provided for shall forthwith cease to be
                    payable to the Holders of such Debentures of the First
                    Series on such Regular Record Date, and may be paid to
                    the Persons in whose name the Debentures of the First
                    Series are registered at the close of business on a
                    Special Record Date to be fixed by the Trustee for the
                    payment of such Defaulted Interest.  Notice of such
                    Defaulted Interest and Special Record Date shall be
                    given to the Holders of the Debentures of the First
                    Series not less than 10 days prior to such Special
                    Record Date, or may be paid at any time in any other
                    lawful manner not inconsistent with the requirements of
                    any securities exchange on which the Debentures of the
                    First Series may be listed, and upon such notice as may
                    be required by such exchange, all as more fully
                    provided in the Indenture;

               6.   The principal and each installment of interest on the
                    Debentures of the First Series shall be payable at, and
                    registration and registration of transfers and
                    exchanges in respect of the Debentures of the First
                    Series may be effected at, the office or agency of the
                    Company in The City of New York; provided, however,
                    that payment of interest may be made at the option of
                    the Company by check mailed to the address of the
                    persons entitled thereto under the Indenture.  Notices,
                    demands to or upon the Company in respect of the
                    Debentures of the First Series may be served at the
                    office or agency of the Company in The City of New
                    York. The Trustee will initially be the agency of the
                    Company for such service of notices and demands;
                    provided, however, that the Company reserves the right
                    to change, by one or more Officer's Certificates any
                    such office or agency.  The Company will be the

                    Debentures of the First Series;

        
               7.   The Debentures of the First Series will be redeemable
                    on or after ________________ at the option of the
                    Company, at any time and from time to time, in whole or

                    principal amount of the Debentures of the First Series
                    being redeemed, together with any accrued interest,
                    including Additional Interest, if any, to the
                    redemption date, upon not less than 30 nor more than 60
                    days' notice given as provided in the Indenture.  
         

        
                    The Debentures of the First Series will also be
                    redeemable at any time at the option of the Company
                    upon the occurrence and during the continuation of a

                    days' notice given as provided in the Indenture.  "Tax
                    Event" means the receipt by the Trust of an opinion of
                    counsel (which may be counsel to the Company or an

                    acceptable to the Property Trustee under the Trust
                    Agreement) 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

                    of any official administrative or judicial
                    pronouncement or decision interpreting or applying such

                    effective or which pronouncement or decision is
                    announced on or after the date of original issuance of
                    the ____% Trust Preferred Capital Securities of the
                    Trust (the "Preferred Securities"), there is more than
                    an insubstantial risk that at such time or within 90
                    days thereof (i) the Trust is, or will be, subject to

                    Debentures of the First Series, is not, or will not be

                    purposes, or (iii) the Trust is, or will be, subject to
                    more than a de minimis amount of other taxes, duties or

                    regulation by any legislative body, court, governmental
                    agency or regulatory authority to the effect that the
                    Trust is or will be considered an "investment company"
                    that is required to be registered under the Investment

                    becomes effective on or after the date of original
                    issuance of the Preferred Securities;
         

        
                    The Debentures of the First Series will also be
                    redeemable, in whole but not in part, at the option of

                    of the First Series then Outstanding plus any accrued
                    and unpaid interest, including Additional Interest, if
                    any, to the redemption date;
         

        
                    The Company may not redeem less than all the Debentures
                    of the First Series Outstanding unless all accrued and
                    unpaid interest (including any Additional Interest) has
                    been paid in full or duly provided for on all
                    Debentures of the First Series Outstanding under the
                    Indenture for all quarterly interest periods
                    terminating on or prior to the date of redemption; 
         

        
                    Any notice of redemption given with respect to the
                    Debentures of the First Series shall be unconditional;
         

        
               8.   Pursuant to Section 311 of the Indenture, the Company
                    shall have the right, at any time and from time to time
                    during the term of the Debentures of the First Series,
                    to extend the interest payment period to a period not
                    exceeding 20 consecutive quarters (an "Extension
                    Period").  Prior to the end of an Extension Period, the
                    Company may, and at the end of the Extension Period the
                    Company shall, pay all interest accrued and unpaid
                    (together with interest thereon at the rate specified
                    for the Debentures of the First Series, compounded
                    quarterly, to the extent permitted by applicable law). 
                    During any such Extension Period, the Company shall not
                    declare or pay any dividend or distribution (other than
                    a dividend or distribution in common stock of the
                    Company) on, or redeem, purchase, acquire or make a
                    liquidation payment with respect to, any of its capital
                    stock, or make any payment of principal, interest or
                    premium, if any, on or repay, repurchase or redeem any
                    indebtedness that is pari passu with the Debentures of
                    the First Series (including other Securities issued
                    under the Indenture), or make any guarantee payments
                    with respect to the foregoing.  Prior to the
                    termination of any such Extension Period, the Company
                    may further extend the interest payment period,
                    provided that such Extension Period together with all
                    such previous and further extensions thereof shall not
                    exceed 20 consecutive quarters at any one time or
                    extend beyond the Stated Maturity of the Debentures of
                    the First Series.  Upon the termination of any such
                    Extension Period and the payment of all amounts then
                    due, the Company may select a new Extension Period,
                    subject to the above requirements.  No interest shall
                    be due and payable during an Extension Period, except
                    at the end thereof.  The Company will give the Trust or
                    other Holders and the Trustee notice of its election of
                    an Extension Period prior to the earlier of (i) one
                    Business Day prior to the record date for the interest
                    payment which would occur but for such election or (ii)
                    the date the Company is required to give notice to the
                    New York Stock Exchange or other applicable
                    self-regulatory organization of the record date;
         

        
               9.   In the event that, at any time subsequent to the
                    initial authentication and delivery of the Debentures
                    of the First Series, the Debentures of the First Series
                    are to be held by a securities depositary, the Company
                    may at such time establish the matters contemplated in
                    clause (r) in the second paragraph of Section 301 of
                    the Indenture in an Officer's Certificate supplemental
                    to this Certificate;
         

        
               10.  No service charge shall be made for the registration of
                    transfer or exchange of the Debentures of the First
                    Series; provided, however, that the Company may require
                    payment of a sum sufficient to cover any tax or other
                    governmental charge that may be imposed in connection
                    with the exchange or transfer;
         

        
               11.  The Debentures of the First Series shall have such
                    other terms and provisions as are provided in the form
                    set forth in Exhibit A hereto, and shall be issued in
                    substantially such form;
         

        
               12.  In the event that the Debentures of the First Series
                    are distributed to holders of the Preferred Securities
                    as a result of the occurrence of (i) a Tax Event or
                    (ii) an Investment Company Event, the Company will use
                    its best efforts to list the Debentures of the First
                    Series on the New York Stock Exchange or on such other
                    exchange as the Preferred Securities are then listed;
         

        
               13.  The undersigned has read all of the covenants and
                    conditions contained in the Indenture relating to the
                    issuance of the Debentures of the First Series and the
                    definitions in the Indenture relating thereto and in
                    respect of which this certificate is made;
         

        
               14.  The statements contained in this certificate are based
                    upon the familiarity of the undersigned with the
                    Indenture, the documents accompanying this certificate,
                    and upon discussions by the undersigned with officers
                    and employees of the Company familiar with the matters

               DELMARVA POWER & LIGHT COMPANY, a corporation duly organized
          and existing under the laws of the States of Delaware and
          Virginia (herein referred to as the "Company," which term
          includes any successor Person under the Indenture), for value
          received, hereby promises to pay to _________________________     
          _________________________ , or registered assigns, the principal
          sum of __________________________ Dollars on
          _____________________, and to pay interest on said principal sum,
          from and including, ____________________ or from, and excluding,
          the most recent Interest Payment Date through which interest has
          been paid or duly provided for, quarterly on March 31, June 30,
          September 30 and December 31 of each year, commencing __________,
          1996 at the rate of ____% per annum until the principal hereof is
          paid or made available for payment.  The amount of interest
          payable on any Interest Payment Date shall be computed on the
          basis of a 360-day year of twelve 30-day months.  Interest on the
          Securities of this series will accrue from, and including,
          _________________ through the first Interest Payment Date, and
          thereafter will accrue, from, and excluding, the last Interest
          Payment Date through which interest has been paid or duly
          provided for. In the event that any Interest Payment Date is not
          a Business Day, then payment of interest payable on such date
          will be made on the next succeeding day which is a Business Day,
          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 as if made on the Interest Payment Date. The interest so
          payable, and punctually paid or duly provided for, on any
          Interest Payment Date will, as provided in such Indenture, be
          paid to the Person in whose name this Security (or one or more
          Predecessor Securities) is registered at the close of business on
          the Regular Record Date for such interest, which shall be the
          Business Day 15 days preceding such Interest Payment Date.  Any
          such interest not so punctually paid or duly provided for will
          forthwith cease to be payable to the Holder on such Regular
          Record Date and may either be paid to the Person in whose name
          this Security (or one or more Predecessor Securities) is
          registered at the close of business on a Special Record Date for
          the payment of such Defaulted Interest to be fixed by the
          Trustee, notice whereof shall be given to Holders of Securities
          of this series not less than 10 days prior to such Special Record
          Date, or be paid at any time in any other lawful manner not
          inconsistent with the requirements of any securities exchange on
          which the Securities of this series may be listed, and upon such
          notice as may be required by such exchange, all as more fully
          provided in the Indenture referred to on the reverse hereof.
         

                    Payment of the principal of and premium, if any, and
          interest on this Security will be made at the office or agency of
          the Company maintained for that purpose in The City of New York,
          the State of New York in such coin or currency of the United
          States of America as at the time of payment is legal tender for
          payment of public and private debts; provided, however, that, at
          the option of the Company, interest on this Security may be paid
          by check mailed to the address of the person entitled thereto, as
          such address shall appear on the Security Register.

                    Reference is hereby made to the further provisions of
          this Security set forth on the reverse hereof, which further
          provisions shall for all purposes have the same effect as if set
          forth at this place.

                    Unless the certificate of authentication hereon has
          been executed by the Trustee referred to on the reverse hereof by
          manual signature, this Security shall not be entitled to any
          benefit under the Indenture or be valid or obligatory for any
          purpose.

                    IN WITNESS WHEREOF, the Company has caused this
          instrument to be duly executed.

                       REVERSE OF JUNIOR SUBORDINATED DEBENTURE

                    This Security is one of a duly authorized issue of
          securities of the Company (herein called the "Securities"),
          issued and to be issued in one or more series under an Indenture,
          dated as of ______________, 1996 (herein, together with any
          amendments thereto, called the "Indenture," which term shall have
          the meaning assigned to it in such instrument), between the
          Company and Wilmington Trust Company, as Trustee (herein called
          the "Trustee," which term includes any successor trustee under
          the Indenture), and reference is hereby made to the Indenture,
          including the Board Resolutions and Officer's Certificate filed
          with the Trustee on ________________, 1996, creating the series
          designated on the face hereof, for a statement of the respective
          rights, limitations of rights, duties and immunities thereunder
          of the Company, the Trustee and the Holders of the Securities and
          of the terms upon which the Securities are, and are to be,
          authenticated and delivered.  This Security is one of the series
          designated on the face hereof, limited in aggregate principal
          amount to $________________.

                    The Securities of this series are subject to redemption
          upon not less than 30 nor more than 60 days' notice by mail, at
          any time on or after _________________ as a whole or in part, at
          the election of the Company, at a Redemption Price equal to 100%
          of the principal amount, together in the case of any such
          redemption with accrued interest to, but not including, the
          Redemption Date, but interest installments whose Stated Maturity
          is on or prior to such Redemption Date will be payable to the
          Holder of such Security, or one or more Predecessor Securities,
          of record at the close of business on the related Regular Record
          Date referred to on the face hereof, all as provided in the
          Indenture.

        
                    The Securities of this series also will be redeemable
          at the option of the Company if a Tax Event or an Investment
          Company Event shall occur and be continuing, in whole but not in
          part, at a redemption price equal to 100% of the principal amount
          of the Securities of this series then Outstanding plus any
          accrued and unpaid interest, including Additional Interest, if
          any, to the redemption date, upon not less than 30 nor more than
          60 days' notice given as provided in the Indenture.  "Tax Event"
          means the receipt by Delmarva Power Financing I, a Delaware
          statutory business trust (the "Trust") of an opinion of counsel
          (which may be counsel to the Company or an affiliate but not an
          employee thereof and which must be acceptable to the Property
          Trustee under the Trust Agreement) 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 as a result of any official administrative or
          judicial pronouncement or decision interpreting or applying such
          laws or regulations, which amendment or change is effective or
          which pronouncement or decision is announced on or after the date
          of original issuance of the ____% Trust Preferred Capital
          Securities of the Trust (the "Preferred Securities"), there is
          more than an insubstantial risk that at such time or within 90
          days thereof (i) the Trust is, or will be, subject to United
          States federal income tax with respect to income received or
          accrued on the Securities, (ii) interest payable by the Company
          on the Securities, is not, or will not be, fully deductible for
          United States federal income tax purposes, or (iii) the Trust is,
          or will be, subject to more than a de minimis amount of other
          taxes, duties or other governmental charges.  "Investment Company
          Event" means the occurrence of a change in law or regulation or a
          change in interpretation or application of law or regulation by
          any legislative body, court, governmental agency or regulatory
          authority to the effect that the Trust is or will be considered
          an "investment company" that is required to be registered under
          the Investment Company Act of 1940, as amended, which change in
          law becomes effective on or after the date of original issuance
          of the Preferred Securities.
         

                    The Securities of this series also will be redeemable,
          in whole but not in part, at the option of the Company upon the
          termination and liquidation of the Trust pursuant to an order for
          the dissolution, termination or liquidation of the Trust entered
          by a court of competent jurisdiction at a redemption price equal
          to 100% of the principal amount of the Securities of this series
          then Outstanding plus any accrued and unpaid interest, including
          Additional Interest, if any, to the redemption date, upon not
          less than 30 nor more than 60 days' notice given as provided in
          the Indenture.

                    In the event of redemption of this Security in part
          only, a new Security or Securities of this series and of like
          tenor for the unredeemed portion hereof will be issued in the
          name of the Holder hereof upon the cancellation hereof.

                    The indebtedness evidenced by this Security is, to the
          extent provided in the Indenture, subordinated and subject in
          right of payment to the prior payment in full of all Senior
          Indebtedness, and this Security is issued subject to the
          provisions of the Indenture with respect thereto.  Each Holder of
          this Security, by accepting the same, (a) agrees to and shall be
          bound by such provisions, (b) authorizes and directs the Trustee
          on his behalf to take such action as may be necessary or
          appropriate to acknowledge or effectuate the subordination so
          provided and (c) appoints the Trustee his attorney-in-fact for
          any and all such purposes.  Each Holder hereof, by his acceptance
          hereof, hereby waives all notice of the acceptance of the
          subordination provisions contained herein and in the Indenture by
          each holder of Senior Indebtedness, whether now outstanding or
          hereafter incurred, and waives reliance by each such Holder upon
          said provisions.

                    The Indenture contains provisions for defeasance at any
          time of the entire  indebtedness of this Security upon compliance
          with certain conditions set forth in the Indenture.

                    If an Event of Default with respect to Securities of
          this series shall occur and be continuing, the principal of the
          Securities of this series may be declared due and payable in the
          manner and with the effect provided in the Indenture.

                    The Indenture permits, with certain exceptions as
          therein provided, the amendment thereof and the modification of
          the rights and obligations of the Company and the rights of the
          Holders of the Securities of each series to be affected under the
          Indenture at any time by the Company and the Trustee with the
          consent of the Holders of a majority in principal amount of the
          Securities at the time Outstanding of all series to be affected. 
          The Indenture also contains provisions permitting the Holders of
          specified percentages in principal amount of the Securities of
          each series at the time Outstanding, on behalf of the Holders of
          all Securities of such series, to waive compliance by the Company
          with certain provisions of the Indenture and certain past
          defaults under the Indenture and their consequences.  Any such
          consent or waiver by the Holder of this Security shall be
          conclusive and binding upon such Holder and upon all future
          Holders of this Security and of any Security issued upon the
          registration of transfer hereof or in exchange herefor or in lieu
          hereof, whether or not notation of such consent or waiver is made
          upon this Security.

                    As provided in and subject to the provisions of the
          Indenture, the Holder of this Security shall not have the right
          to institute any proceeding with respect to the Indenture or for
          the appointment of a receiver or trustee or for any other remedy
          thereunder, unless such Holder shall have previously given the
          Trustee written notice of a continuing Event of Default with
          respect to the Securities of this series, the Holders of not less
          than a majority in aggregate principal amount of the Securities
          of all series at the time Outstanding in respect of which an
          Event of Default shall have occurred and be continuing shall have
          made written request to the Trustee to institute proceedings in
          respect of such Event of Default as Trustee and offered the
          Trustee reasonable indemnity, and the Trustee shall not have
          received from the Holders of a majority in aggregate principal
          amount of Securities of all series at the time Outstanding in
          respect of which an Event of Default shall have occurred and be
          continuing a direction inconsistent with such request, and shall
          have failed to institute any such proceeding, for 60 days after
          receipt of such notice, request and offer of indemnity.  The
          foregoing shall not apply to any suit instituted by the Holder of
          this Security for the enforcement of any payment of principal
          hereof or any premium or interest hereon on or after the
          respective due dates expressed herein.

                    No reference herein to the Indenture and no provision
          of this Security or of the Indenture shall alter or impair the
          obligation of the Company, which is absolute and unconditional,
          to pay the principal of and any premium and interest on this
          Security at the times, place and rate, and in the coin or
          currency, herein prescribed.

        
                    The Company has the right at any time and from time to
          time during the term of the Securities of this series to extend
          the interest payment period to a period not exceeding 20
          consecutive quarters (an "Extension Period").  Prior to the end
          of an Extension Period, the Company may, and at the end of such
          Extension Period, the Company shall, pay all interest then
          accrued and unpaid (together with interest thereon at the same
          rate as specified for the Securities of this series, compounded
          quarterly, to the extent permitted by applicable law).  During
          any such Extension Period the Company shall not declare or pay
          any dividend or  distribution (other than a dividend or
          distribution in common stock of the Company) on, or redeem,
          purchase, acquire or make a liquidation payment with respect to,
          any of its capital stock, or make any payment of principal on,
          interest or premium if any, on or repay, repurchase or redeem any
          indebtedness that is pari passu with the Securities of this
          series (including other Securities issued under the Indenture),
          or make any guarantee payments with respect to the foregoing. 
          Prior to the termination of any such Extension Period, the
          Company may further extend the interest payment period, provided
          that such Extension Period, together with all such previous and
          further extensions thereof, may not exceed 20 consecutive
          quarters or extend beyond the Stated Maturity of the Securities
          of this series.  Upon the termination of any such Extension
          Period and the payment of all amounts then due, the Company may
          select a new Extension Period, subject to the above requirements. 
          No interest during the Extension Period, except at the end
          thereof, shall be due and payable.  The Company shall give the
          Holder of this Security notice of its selection of such Extension
          Period as provided in or pursuant to the Indenture.
            

                    The Securities of this series are issuable only in
          registered form without coupons in denominations of $25 and any
          integral multiple thereof.  As provided in the Indenture and
          subject to certain limitations therein set forth, Securities of
          this series are exchangeable for a like aggregate principal
          amount of Securities of this series and of like tenor and of
          authorized denominations, as requested by the Holder surrendering
          the same.

                    As provided in the Indenture, the Company shall not be
          required to make transfers or exchanges of Securities of this
          series for a period of 15 days immediately preceding the date of
          the mailing of any notice of redemption of such Securities and
          the Company shall not be required to make transfers or exchanges
          of any Securities of this series so selected for redemption in
          whole or in part (except the unredeemed portion of thereof).

                    No service charge shall be made for any such
          registration of transfer or exchange, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge payable in connection therewith.

                    The Company, the Trustee and any agent of the Company
          or the Trustee may treat the Person in whose name this Security
          is registered as the absolute owner hereof for all purposes,
          whether or not this Security be overdue, and neither the Company,
          the Trustee nor any such agent shall be affected by notice to the
          contrary.

                    All terms used in this Security which are defined in
          the Indenture shall have the meanings assigned to them in the
          Indenture.
