(1) Subject to the following sentence, there is being registered hereunder an
    indeterminate number of Preferred Securities of Potomac Electric Power
    Company Trust I (the "Trust") and an indeterminate principal amount of
    Junior Subordinated Debentures of Potomac Electric Power Company ("PEPCO")
    . In no event will the aggregate initial offering price of the Preferred
    Securities exceed $125,000,000, exclusive of accrued distributions, if
    any. A like amount of Junior Subordinated Debentures will be issued and
    sold by PEPCO to the Trust. The Junior Subordinated Debentures may later
    be distributed for no additional consideration to the holders of the
    Preferred Securities upon a dissolution of the Trust and the distribution
    of the assets thereof. The proposed maximum aggregate offering price has
    been estimated solely for the purpose of calculating the registration fee
    pursuant to Rule 457(o) under the Securities Act of 1933.
(2) The proposed maximum offering price per unit will be determined from time
    to time in connection with the issuance of the securities registered
    hereunder.
(3) Consists of the rights of holders of the Preferred Securities under the
    Guarantee and certain back-up undertakings, comprised of the obligations
    of PEPCO under the Declaration of Trust as issuer of the Junior
    Subordinated Debentures to provide certain indemnities in respect of, and
    pay and be responsible for certain costs, expenses, debts and liabilities
    of, the Trust (other than with respect to the Preferred Securities) and
    such obligations of PEPCO as set forth in the Declaration of Trust and the
    Indenture, in each case as amended from time to time and as further
    described in the Registration Statement. The Guarantee, when taken
    together with PEPCO's obligations under the Junior Subordinated
    Debentures, the Indenture and the Declaration of Trust, will provide a
    full and unconditional guarantee on a subordinated basis by PEPCO of
    payments due on the Preferred Securities. No separate consideration will
    be received for any Guarantee or such back-up obligations.
 
                                --------------
  THE REGISTRANTS HEREBY AMEND THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANTS
SHALL FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS
REGISTRATION STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH
SECTION 8(A) OF THE SECURITIES ACT OF 1933 OR UNTIL THIS REGISTRATION
STATEMENT SHALL BECOME EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING
PURSUANT TO SAID SECTION 8(A), MAY DETERMINE.

                    FULLY AND UNCONDITIONALLY GUARANTEED BY
                         POTOMAC ELECTRIC POWER COMPANY
 
  Potomac Electric Power Company Trust I (the "Trust"), a statutory business
trust formed under the laws of the State of Delaware by Potomac Electric Power
Company, a District of Columbia and Virginia corporation ("PEPCO" or the
"Company"), is offering preferred securities representing undivided beneficial
interests in the assets of the Trust ("Preferred Securities"). The payment of
periodic cash distributions ("distributions") with respect to Preferred
Securities out of moneys held by the Trust, and payments on liquidation,
redemption or otherwise with respect to such Preferred Securities, will be
guaranteed by PEPCO to the extent described herein (the "Preferred Securities
Guarantee"). See "Description of the Preferred Securities Guarantee." PEPCO's
obligations under the Preferred Securities Guarantee will be subordinate and
junior in right of payment to all other liabilities of PEPCO and will rank pari
passu with the most senior preferred or preference stock, if any, issued from
time to time by PEPCO. The Trust will invest the proceeds from the offering of
Preferred Securities and Common Securities (as defined herein) in subordinated
debt securities ("Junior Subordinated Debentures") issued by PEPCO. The Junior
Subordinated Debentures purchased by the Trust may be subsequently distributed
pro rata to holders of Preferred Securities and Common Securities in connection
with the dissolution of the Trust upon the occurrence of certain events as
described in an accompanying Prospectus Supplement (the "Prospectus
Supplement"). The Preferred Securities, the Preferred Securities Guarantee and
the Junior Subordinated Debentures are sometimes collectively referred to
hereafter as the "Offered Securities."
 
  The form in which the Offered Securities are to be issued, their specific
designation, aggregate principal amount or liquidation value or aggregate
initial offering price, maturity, if any, rate and times of payment of interest
or dividends, if any, redemption, conversion, and sinking fund terms, if any,
voting or other rights, if any, exercise price and detachability, if any, and
other specific terms will be set forth in the Prospectus Supplement, together
with the terms of offering of such Offered Securities. Any such Prospectus
Supplement will also contain information, as applicable, about certain material
United States federal income tax considerations relating to the particular
Offered Securities offered thereby.
 
  PEPCO and/or the Trust may sell the Offered Securities directly, through
agents designated from time to time, or through underwriters or dealers. See
"Plan of Distribution." If any agents of PEPCO and/or the Trust or any
underwriters or dealers are involved in the sale of the Offered Securities, the
names of such agents, underwriters or dealers and any applicable commissions
and discounts will be set forth in any related Prospectus Supplement.
 
  This Prospectus may not be used to consummate sales of securities unless
accompanied by a Prospectus Supplement.
 
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE COMMISSION  OR ANY STATE SECURITIES COMMISSION NOR HAS  THE SECURITIES
 AND EXCHANGE COMMISSION  OR ANY  STATE SECURITIES COMMISSION  PASSED UPON THE
 ACCURACY OR  ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION  TO THE CONTRARY
  IS A CRIMINAL OFFENSE.

                             AVAILABLE INFORMATION
 
  This Prospectus constitutes a part of a combined Registration Statement on
Form S-3 (together with all amendments and exhibits thereto, the "Registration
Statement") filed by PEPCO and the Trust with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to the Offered Securities. This
Prospectus does not contain all of the information set forth in such
Registration Statement, certain parts of which are omitted in accordance with
the rules and regulations of the Commission, although it does include a
summary of the material terms of the Indenture and the Declaration (each as
defined herein). Reference is made to such Registration Statement and to the
exhibits thereto for further information with respect to the Company, the
Trust and the Offered Securities. Any statements contained herein concerning
the provisions of any document filed as an exhibit to the Registration
Statement or otherwise filed with the Commission or incorporated by reference
herein are not necessarily complete, and, in each instance, reference is made
to the copy of such document so filed for a more complete description of the
matter involved. Each such statement is qualified in its entirety by such
reference.
 
  PEPCO is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Commission. Proxy statements, reports and other information concerning PEPCO
can be inspected and copied at the Commission's office at Room 1024, Judiciary
Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549 and the Commission's
Regional Offices in New York (Suite 1300, Seven World Trade Center, New York,
New York 10048) and Chicago (Northwestern Atrium Center, 500 West Madison
Street, Suite 1400, Chicago, Illinois 60661), and copies of such material can
be obtained from the Public Reference Section of the Commission at 450 Fifth
Street, N.W., Washington, D.C. 20549, at prescribed rates, or by accessing the
Commission's World Wide Web site at http://www.sec.gov. The common stock,
$1.00 par value, of PEPCO (the "Common Stock") and other securities of PEPCO
are listed on the New York Stock Exchange ("NYSE"). Reports, proxy material
and other information concerning PEPCO also may be inspected at the offices of
the NYSE, 20 Broad Street, New York, New York 10005.
 
  No separate financial statements of the Trust have been included herein.
PEPCO does not consider that such financial statements would be material to
holders of the Preferred Securities because (i) all of the voting securities
of the Trust will be owned, directly or indirectly, by PEPCO, a reporting
company under the Exchange Act, (ii) the Trust has no independent operations
but exists for the sole purpose of issuing securities representing undivided
beneficial interests in the assets of the Trust and investing the proceeds
thereof in Junior Subordinated Debentures issued by PEPCO, and (iii) PEPCO's
obligations described herein and in any accompanying Prospectus Supplement to
provide certain indemnities in respect of, and be responsible for, certain
costs, expenses, debts and liabilities of the Trust under the Indenture and
any supplemental indenture thereto and pursuant to the Declaration, the
Preferred Securities Guarantee issued with respect to Preferred Securities,
the Junior Subordinated Debentures purchased by the Trust and the Indenture,
taken together, constitute a full and unconditional guarantee of payments due
on the Preferred Securities. See "Description of the Junior Subordinated
Debentures" and "Description of the Preferred Securities Guarantee."
 
  The Trust is not currently subject to the informational requirements of the
Exchange Act. The Trust will become subject to such requirements upon the
effectiveness of the Registration Statement, although it intends to seek and
expects to receive an exemption therefrom.

<PAGE>
 
                                   THE TRUST
 
  The Trust is a statutory business trust formed under Delaware law pursuant
to (i) a declaration of trust executed by PEPCO, as sponsor for the Trust (the
"Sponsor"), and the Trustees (as defined herein) of the Trust, as amended and
restated from time to time (the "Declaration"), and (ii) the filing of a
certificate of trust with the Delaware Secretary of State. The Trust exists
for the exclusive purposes of (i) issuing the Preferred Securities and common
securities representing undivided beneficial interests in the assets of the
Trust (the "Common Securities" and, together with the Preferred Securities,
the "Trust Securities"), (ii) investing the gross proceeds from the sale of
the Trust Securities in Junior Subordinated Debentures, and (iii) engaging in
only those other activities necessary or incidental thereto. All of the Common
Securities will be directly or indirectly owned by PEPCO. The Common
Securities will rank pari passu, and payments will be made thereon pro rata,
with the Preferred Securities, except that upon an event of default under the
Declaration with respect thereto, the rights of the holders of the Common
Securities to payment in respect of distributions and to payments upon
liquidation, redemption and otherwise will be subordinated to the rights of
the holders of the Preferred Securities. PEPCO will, directly or indirectly,
acquire Common Securities in an aggregate liquidation amount equal to at least
3 percent of the total capital of the Trust.
 
  The Trust has a term of approximately 50 years, but may terminate earlier as
provided in the Declaration. The Trust's business and affairs will be
conducted by the trustees (the "Trustees") appointed by PEPCO, as the direct
or indirect holder of all the Common Securities. The holder of the Common
Securities will be entitled to appoint, remove or replace any of, or increase
or reduce the number of, the Trustees. The duties and obligations of the
Trustees shall be governed by the Declaration. One or more of the Trustees
will be persons who are employees or officers of PEPCO (the "Regular
Trustees"). One Trustee will be a financial institution which will be
unaffiliated with PEPCO and which shall act as institutional trustee under the
Declaration and as indenture trustee for purposes of the Trust Indenture Act
of 1939, as amended (the "Trust Indenture Act"), pursuant to the terms set
forth in a Prospectus Supplement (the "Institutional Trustee"). In addition,
unless the Institutional Trustee maintains a principal place of business in
the State of Delaware, and otherwise meets the requirements of applicable law,
one Trustee will have its principal place of business or reside in the State
of Delaware (the "Delaware Trustee"). PEPCO will pay all fees and expenses
related to the Trust and the offering of Trust Securities.
 
               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES
 
  The Junior Subordinated Debentures will be issued under an indenture, as it
may be supplemented from time to time (the "Indenture"), between the Company
and The Bank of New York, as trustee (the "Debt Trustee"). The form of the
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part. The terms of the Junior Subordinated Debentures
will include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act. While the following summary
of the material terms does not purport to be complete and is subject in all
respects to the provisions of, and is qualified in its entirety by reference
to, the Indenture and the Trust Indenture Act, all material terms of the
Junior Subordinated Debentures are set forth herein and in any Prospectus
Supplement relating to the particular Junior Subordinated Debentures being
offered thereby.
 
GENERAL
 
  The Junior Subordinated Debentures will be unsecured obligations of the
Company. The Indenture does not limit the aggregate principal amount of Junior
Subordinated Debentures which may be issued thereunder and provides that the
Junior Subordinated Debentures may be issued from time to time in one or more
series.
 
  The Junior Subordinated Debentures may be distributed pro rata to the
holders of the Trust Securities in connection with the dissolution of the
Trust upon the occurrence of certain events described in the Prospectus
Supplement.
 
                                       4
<PAGE>
 
  Reference is made to the Prospectus Supplement relating to the particular
Junior Subordinated Debentures being offered thereby for the following terms:
(1) the designation of such Junior Subordinated Debentures; (2) the aggregate
principal amount of such Junior Subordinated Debentures; (3) the percentage of
their principal amount at which such Junior Subordinated Debentures will be
issued; (4) the date or dates on which such Junior Subordinated Debentures
will mature and the right, if any, to shorten or extend such date or dates;
(5) the rate or rates, if any, per annum, at which such Junior Subordinated
Debentures will bear interest, or the method of determination of such rate or
rates; (6) the date or dates from which such interest shall accrue, the
interest payment dates on which such interest will be payable or the manner of
determination of such interest payment dates and the record dates for the
determination of holders to whom interest is payable on any such interest
payment dates; (7) the right, if any, to extend the interest payment periods
and the duration of such extension; (8) provisions, if any, for a sinking
purchase or other analogous fund; (9) the period or periods, if any, within
which, the price or prices of which, and the terms and conditions upon which
such Junior Subordinated Debentures may be redeemed, in whole or in part, at
the option of PEPCO or the holder; (10) the form of such Junior Subordinated
Debentures; and (11) any other specific terms of the Junior Subordinated
Debentures.
 
  The covenants contained in the Indenture would not necessarily afford
protection to holders of the Junior Subordinated Debentures in the event of a
decline in credit quality resulting from takeovers, recapitalizations or
similar restructurings.
 
FORM, EXCHANGE, REGISTRATION, TRANSFER AND PAYMENT
 
  Unless otherwise specified in the Prospectus Supplement, the Junior
Subordinated Debentures will be issued in fully registered form without
coupons and in denominations of $1,000 and multiples of $1,000. No service
charge will be made for any transfer or exchange of the Junior Subordinated
Debentures, but the Company or the Debt Trustee may require payment of a sum
sufficient to cover any tax or other government charge payable in connection
therewith.
 
  Unless otherwise provided in the Prospectus Supplement, principal and
premium, if any, or interest, if any, will be payable and the Junior
Subordinated Debentures may be surrendered for payment or transferred at the
offices of the Debt Trustee as paying and authenticating agent, provided that
payment of interest on Junior Subordinated Debentures that are not held by the
Trust may be made at the option of PEPCO by check mailed to the address of the
person entitled thereto as it appears in the security register.
 
BOOK-ENTRY JUNIOR SUBORDINATED DEBENTURES
 
  The Junior Subordinated Debentures of a series may be issued, in whole or in
part, in the form of one or more instruments that will be deposited with, or
on behalf of, a depositary (the "Global Depositary"), or its nominee,
identified in the Prospectus Supplement relating to such series (a "Global
Security"). In such a case, one or more Global Securities will be issued in a
denomination or aggregate denomination equal to the portion of the aggregate
principal amount of outstanding Junior Subordinated Debentures of the series
to be represented by such Global Security or Securities. Unless and until it
is exchanged in whole or in part for Junior Subordinated Debentures in
definitive registered form, a Global Security may not be registered for
transfer or exchange, except as a whole by the Global Depositary to a nominee
for such Global Depositary and except in the circumstances described in the
Prospectus Supplement.
 
  The specific terms of the depositary arrangement with respect to any portion
of the Junior Subordinated Debentures to be represented by a Global Security
and a description of the Global Depositary will be provided in the Prospectus
Supplement.
 
SUBORDINATION
 
  The Junior Subordinated Debentures will be subordinated and junior in right
of payment to certain other indebtedness of PEPCO to the extent set forth in
the Prospectus Supplement.

CERTAIN COVENANTS OF PEPCO
 
  If (i) there shall have occurred any event that would constitute an
Indenture Event of Default (as defined herein) or (ii) PEPCO shall be in
default with respect to its payment of any obligations under the related
Preferred Securities Guarantee or Common Securities Guarantee (as defined
herein), or (iii) PEPCO shall have given notice of its election to defer
payments of interest on such Junior Subordinated Debentures by extending the
interest payment period as provided in the Supplemental Indenture and such
period, or any extension thereof, shall be continuing, then (a) PEPCO shall
not declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any
of its capital stock (other than (y) purchases or acquisitions of shares of
Common Stock in connection with the satisfaction by PEPCO of its obligations
under any employee benefit plans or any other contractual obligation of PEPCO
(other than a contractual obligation ranking pari passu with or junior to the
Junior Subordinated Debentures) or (z) the purchase of fractional interests in
shares of PEPCO capital stock pursuant to the conversion or exchange
provisions of such PEPCO capital stock or the security being converted or
exchanged), (b) PEPCO shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued
by PEPCO which rank pari passu with or junior to such Junior Subordinated
Debentures and (c) PEPCO shall not make any guarantee payments with respect to
the foregoing (other than pursuant to the Preferred Securities Guarantee).
 
  For so long as the Trust Securities remain outstanding, PEPCO will covenant
(i) directly or indirectly to maintain 100 percent ownership of the Common
Securities; provided, however, that any permitted successor of PEPCO under the
Indenture may succeed to PEPCO's ownership of such Common Securities, (ii) to
use its reasonable efforts to cause the Trust (a) to remain a statutory
business trust, except in connection with the distribution of Junior
Subordinated Debentures to the holders of Trust Securities in liquidation of
the Trust, the redemption of all of the Trust Securities, or certain mergers,
consolidations or amalgamations, each as permitted by the Declaration, and (b)
otherwise to continue not to be treated as an association taxable as a
corporation or a partnership for United States federal income tax purposes and
(iii) to use its reasonable efforts to cause each holder of Trust Securities
to be treated as owning an undivided beneficial interest in the Junior
Subordinated Debentures.
 
LIMITATION ON MERGERS AND SALES OF ASSETS
 
  PEPCO shall not consolidate with, or merge into, any corporation or convey
or transfer its properties and assets substantially as an entirety to any
person or entity unless (a) the successor shall be a corporation organized
under the laws of any domestic jurisdiction and shall expressly assume the
obligations of PEPCO under the Indenture and (b) after giving effect thereto,
no default shall have occurred and be continuing under the Indenture.
 
EVENTS OF DEFAULT, WAIVER AND NOTICE
 
  The Indenture provides that any one or more of the following described
events which has occurred and is continuing constitutes an event of default
with respect to each series of Junior Subordinated Debentures (an "Indenture
Event of Default"):
 
    (a) default for 30 days in payment of any interest on the Junior
  Subordinated Debentures of that series, when due; provided, however, that a
  valid extension of the interest payment period by the Company shall not
  constitute a default in the payment of interest for this purpose; or
 
    (b) default in payment of principal of, or premium, if any, on, the
  Junior Subordinated Debentures of that series when due either at maturity,
  upon redemption, by declaration or otherwise; provided, however, that a
  valid extension of the maturity of such Junior Subordinated Debentures
  shall not constitute a default for this purpose; or
 
    (c) default by the Company in the performance of any other of the
  covenants or agreements in the Indenture which shall not have been remedied
  for a period of 90 days after notice to PEPCO; or
 
    (d) certain events of bankruptcy, insolvency or reorganization of PEPCO;
  or
 
                                       6
<PAGE>
 
    (e) after Junior Subordinated Debentures are issued to the Trust in
  connection with the issuance of Trust Securities by the Trust, the
  voluntary or involuntary dissolution, winding-up or termination of the
  Trust, except in connection with the distribution of Junior Subordinated
  Debentures to the holders of Trust Securities in liquidation of the Trust,
  the redemption of all of the Trust Securities, or certain mergers,
  consolidations or amalgamations, each as permitted by the Declaration.
 
  The Indenture provides that, if an Indenture Event of Default on any series
of Junior Subordinated Debentures shall have occurred and be continuing,
either the Debt Trustee or the holders of not less than 25 percent in
aggregate principal amount of the Junior Subordinated Debentures of such
series then outstanding may declare the principal of all such Junior
Subordinated Debentures of such series to be due and payable immediately. The
holders of a majority in aggregate outstanding principal amount of such series
of Junior Subordinated Debentures may annul such declaration and waive the
default if the default (other than the non-payment of the principal of such
series of Junior Subordinated Debentures which has become due solely by such
acceleration) has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Debt Trustee.
 
  The holders of a majority in principal amount of the Junior Subordinated
Debentures of any or all series affected and then outstanding shall have the
right to direct the time, method and place of conducting any proceeding for
any remedy available to the Debt Trustee under the Indenture, provided that
the holders of the Junior Subordinated Debentures shall have offered to the
Debt Trustee reasonable indemnity against expenses and liabilities.
Notwithstanding the foregoing, the right of any holder of Junior Subordinated
Debentures to receive payment of the principal of and interest on such Junior
Subordinated Debentures on or after the due dates therefor, as the same may be
extended in accordance with the terms of such Junior Subordinated Debentures,
or to institute suit for the enforcement of any such payment provisions, shall
not be impaired or affected without the consent of such holder.
 
  The Indenture requires the annual filing by PEPCO with the Debt Trustee of a
certificate as to the absence of defaults under the Indenture.
 
  The Indenture provides that the Debt Trustee may withhold notice to the
holders of a series of Junior Subordinated Debentures of an Indenture Event of
Default (except a default in payment of principal of, or of interest or
premium on, the Junior Subordinated Debentures) if the Debt Trustee in good
faith determines that the withholding of such notice is in the interest of the
holders.
 
MODIFICATION OF THE INDENTURE
 
  The Indenture contains provisions permitting the Company and the Debt
Trustee, with the consent of the holders of not less than a majority in
principal amount of the Junior Subordinated Debentures of all series affected
by such modification at the time outstanding, and the holders of a majority in
aggregate liquidation amount of the related Preferred Securities, to modify
the Indenture or any supplemental indenture or the rights of the holders of
the Junior Subordinated Debentures; provided that no such modification shall,
without the consent of the holders of each Junior Subordinated Debenture (and
each Preferred Security, if applicable) affected thereby, (i) extend the fixed
maturity of any Junior Subordinated Debenture, or reduce the principal amount
thereof or any premium thereon, or reduce any amount payable on redemption
thereof, or reduce the rate or extend the time of payment of interest thereon,
or make the principal of, or interest or premium on, the Junior Subordinated
Debentures payable in any coin or currency other than that provided in the
Junior Subordinated Debentures, or impair or affect the right of any holder of
Junior Subordinated Debentures to institute suit for the payment thereof or
the right of repayment, if any, at the option of the holder, (ii) reduce the
aforesaid percentage of Junior Subordinated Debentures the consent of the
holders of which is required for any such modification or (iii) otherwise
materially adversely affect the interest of the holders of any series of
Junior Subordinated Debentures.
 
DEFEASANCE AND DISCHARGE
 
  The Indenture provides that PEPCO, at PEPCO's option, will be discharged
from any and all obligations in respect of the Junior Subordinated Debentures
of a series (except for certain obligations to register the transfer
 
                                       7
<PAGE>
 
or exchange of Junior Subordinated Debentures, replace destroyed, lost, stolen
or mutilated Junior Subordinated Debentures, maintain paying agencies and hold
moneys for payment in trust) if PEPCO deposits, in trust with the Debt Trustee
or a defeasance agent, money or U.S. government obligations which through the
payment of interest thereon and principal thereof in accordance with their
terms will provide money, in an amount sufficient to pay all the principal
(including any mandatory sinking fund payments) of, and interest and premium,
if any, on, the Junior Subordinated Debentures of such series on the dates
such payments are due in accordance with the terms of such Junior Subordinated
Debentures. To exercise any such option, PEPCO is required to deliver to the
Debt Trustee and the defeasance agent, if any, an opinion of counsel to the
effect that (i) the deposit and related defeasance would not cause the holders
of the Junior Subordinated Debentures of such series to recognize income, gain
or loss for U.S. federal income tax purposes, accompanied by a private letter
ruling to that effect received by PEPCO from the United States Internal
Revenue Service or a revenue ruling pertaining to a comparable form of
transaction to that effect published by the United States Internal Revenue
Service, and (ii) if listed on any national securities exchange, such Junior
Subordinated Debentures would not be delisted from such exchange as a result
of the exercise of such option.
 
GOVERNING LAW
 
  The Indenture and the Junior Subordinated Debentures will be governed by,
and construed in accordance with, the internal laws of the State of New York.
 
THE DEBT TRUSTEE
 
  PEPCO and its affiliates maintain certain accounts and other banking
relationships with the Debt Trustee and its affiliates in the ordinary course
of business. The Debt Trustee also serves as the Preferred Guarantee Trustee
and as trustee under other indentures of PEPCO.
 
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
  The Trust may issue only one series of Preferred Securities. The Preferred
Securities will have the terms described in the Prospectus Supplement. The
Declaration will be qualified as an indenture under the Trust Indenture Act.
The Preferred Securities will have such terms, including distributions,
redemption, voting, liquidation rights and such other preferred, deferred or
other special rights or such restrictions as shall be set forth in the
Declaration or made part of the Declaration by the Trust Indenture Act and
which will mirror the terms of the Junior Subordinated Debentures held by the
Trust and described in the Prospectus Supplement. Reference is made to the
Prospectus Supplement for specific terms, including (i) the distinctive
designation of such Preferred Securities; (ii) the number of Preferred
Securities issuable by the Trust; (iii) the distribution rate (or method of
determining such rate) and the date or dates upon which such distributions
shall be payable; (iv) whether distributions shall be cumulative, and, in the
case of Preferred Securities having such cumulative distribution rights, the
date or dates or method of determining the date or dates from which
distributions shall be cumulative; (v) the amount or amounts which shall be
paid out of the assets of the Trust to the holders of Preferred Securities
upon voluntary or involuntary dissolution, winding-up or termination of the
Trust; (vi) the obligation, if any, of the Trust to purchase or redeem
Preferred Securities and the price or prices at which, the period or periods
within which, and the terms and conditions upon which, Preferred Securities
shall be purchased or redeemed, in whole or in part, pursuant to such
obligation; (vii) the voting rights, if any, of holders of Preferred
Securities in addition to those required by law, including the number of votes
per Preferred Security and any requirement for the approval by the holders of
Preferred Securities as a condition to specified action or amendments to the
Declaration; (viii) the terms and conditions, if any, upon which the Junior
Subordinated Debentures owned by the Trust may be distributed to holders of
Preferred Securities; (ix) if applicable, any securities exchange upon which
the Preferred Securities shall be listed; and (x) any other relevant rights,
preferences, privileges, limitations or restrictions of Preferred Securities
not inconsistent with the Declaration or
 
                                       8
<PAGE>
 
with applicable law. All Preferred Securities offered hereby will be
guaranteed by PEPCO to the extent set forth below under "Description of the
Preferred Securities Guarantee." Certain United States federal income tax
considerations applicable to any offering of Preferred Securities will be
described in the Prospectus Supplement.
 
  In connection with the issuance of Preferred Securities, the Trust will
issue one series of Common Securities. The Declaration authorizes the Regular
Trustees of the Trust to issue on behalf of the Trust one series of Common
Securities having such terms including distributions, redemption, voting,
liquidation rights or such restrictions as shall be set forth therein. Except
for voting rights, the terms of the Common Securities will be substantially
identical to the terms of the Preferred Securities and the Common Securities
will rank pari passu, and payments will be made thereon pro rata, with the
Preferred Securities, except that, upon an event of default under the
Declaration, the rights of the holders of the Common Securities to payment in
respect of distributions and payments upon liquidation, redemption and
otherwise will be subordinated to the rights of the holders of the Preferred
Securities. Except in certain limited circumstances, the Common Securities
will also carry the right to vote to appoint, remove or replace any of the
Trustees of the Trust. All of the Common Securities of the Trust will be owned
directly or indirectly by PEPCO.
 
               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEE
 
  PEPCO will execute and deliver the Preferred Securities Guarantee for the
benefit of the holders from time to time of Preferred Securities. The
Preferred Securities Guarantee will be qualified as an indenture under the
Trust Indenture Act. The Bank of New York will act as indenture trustee under
the Preferred Securities Guarantee for purposes of the Trust Indenture Act
(the "Preferred Guarantee Trustee"). The terms of the Preferred Securities
Guarantee will be those set forth in the Preferred Securities Guarantee and
those made part of such Preferred Securities Guarantee by the Trust Indenture
Act. While the following summary of the material terms of the Preferred
Securities Guarantee does not purport to be complete and is subject in all
respects to the provisions of, and is qualified in its entirety by reference
to, the form of Preferred Securities Guarantee, which is filed as an exhibit
to the Registration Statement of which this Prospectus forms a part, and the
Trust Indenture Act, all material terms of the Preferred Securities Guarantee
are set forth herein and in the Prospectus Supplement relating to the
particular Preferred Securities being offered thereby. The Preferred
Securities Guarantee will be held by the Preferred Guarantee Trustee for the
benefit of the holders of the Preferred Securities.
 
GENERAL
 
  Pursuant to the Preferred Securities Guarantee, PEPCO will agree, to the
extent set forth therein, to pay in full, to the holders of the Preferred
Securities, the Guarantee Payments (as defined herein), as and when due,
regardless of any defense, right of set-off or counterclaim which the Trust
may have or assert. The following payments with respect to Preferred
Securities to the extent not paid by the Trust (the "Guarantee Payments"),
will be covered by the Preferred Securities Guarantee (without duplication):
(i) any accrued and unpaid distributions which are required to be paid on such
Preferred Securities, to the extent the Trust shall have funds available
therefor; (ii) the redemption price, including all accrued and unpaid
distributions to the date of payment (the "Redemption Price"), to the extent
the Trust has funds available therefor, with respect to any Preferred
Securities called for redemption by the Trust; and (iii) upon a voluntary or
involuntary dissolution, winding-up or termination of the Trust (other than in
connection with the distribution of Junior Subordinated Debentures to the
holders of Preferred Securities or the redemption of all of the Preferred
Securities), the lesser of (a) the aggregate of the liquidation amount and all
accrued and unpaid distributions on such Preferred Securities to the date of
payment, to the extent the Trust has funds available therefor, and (b) the
amount of assets of the Trust remaining available for distribution to holders
of such Preferred Securities in liquidation of the Trust. The redemption price
and liquidation amount will be fixed at the time the Preferred Securities are
issued. PEPCO's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by PEPCO to the holders of Preferred
Securities or by causing the Trust to pay such amounts to such holders.
 
                                       9
<PAGE>
 
  The Preferred Securities Guarantee will not apply to any Guarantee Payment,
except to the extent the Trust shall have funds available therefor. If PEPCO
does not make interest payments on the Junior Subordinated Debentures
purchased by the Trust, the Trust will not pay distributions on the Preferred
Securities issued by the Trust and will not have funds available therefor.
 
  The Preferred Securities Guarantee, when taken together with PEPCO's
obligations under the Junior Subordinated Debentures, the Indenture, and the
Declaration, including its obligations to pay costs, expenses, debts and
liabilities of the Trust (other than with respect to the Trust Securities),
will provide a full and unconditional guarantee on a subordinated basis by
PEPCO of payments due on the Preferred Securities.
 
  PEPCO has also agreed separately to guarantee irrevocably and
unconditionally the obligations of the Trust with respect to the Common
Securities (the "Common Securities Guarantee") to the same extent as the
Preferred Securities Guarantee, except that upon an event of default under the
Declaration, holders of Preferred Securities shall have priority over holders
of Common Securities with respect to distributions and payments on
liquidation, redemption or otherwise.
 
CERTAIN COVENANTS OF PEPCO
 
  In the Preferred Securities Guarantee, PEPCO will covenant that, so long as
any Preferred Securities issued remain outstanding, if there shall have
occurred any event that would constitute an event of default under the
Preferred Securities Guarantee or the Declaration, or if PEPCO has exercised
its option to defer interest payments on the Junior Subordinated Debentures by
extending the interest payment period and such period or extension thereof
shall be continuing, then (a) PEPCO shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of shares of Common Stock in connection with the
satisfaction by PEPCO of its obligations under any employee benefit plans or
any other contractual obligation of PEPCO (other than a contractual obligation
ranking pari passu with or junior to the Junior Subordinated Debentures) or
(ii) the purchase of fractional interests in shares of PEPCO capital stock
pursuant to the conversion or exchange provisions of such PEPCO capital stock
or the security being converted or exchanged), (b) PEPCO shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by PEPCO which rank pari passu with or
junior to such Junior Subordinated Debentures and (c) PEPCO shall not make any
guarantee payments with respect to the foregoing (other than pursuant to such
Preferred Securities Guarantee).
 
MODIFICATION OF THE PREFERRED SECURITIES GUARANTEE; ASSIGNMENT
 
  Except with respect to any changes which do not adversely affect the rights
of holders of Preferred Securities (in which case no consent will be
required), the Preferred Securities Guarantee may be amended only with the
prior approval of the holders of at least a majority in liquidation amount of
the outstanding Preferred Securities. The manner of obtaining any such
approval of holders of such Preferred Securities will be as set forth in an
accompanying Prospectus Supplement. All guarantees and agreements contained in
the Preferred Securities Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of PEPCO and shall inure to the
benefit of the holders of the Preferred Securities then outstanding. Except in
connection with any merger or consolidation of PEPCO with or into another
entity or any sale, transfer or lease of PEPCO's assets to another entity,
each as permitted by the Indenture, PEPCO may not assign its rights or
delegate its obligations under such Preferred Securities Guarantee without the
prior approval of the holders of at least a majority in liquidation amount of
the outstanding Preferred Securities.
 
TERMINATION
 
  The Preferred Securities Guarantee will terminate as to the Preferred
Securities (a) upon full payment of the Redemption Price of all Preferred
Securities, (b) upon distribution of the Junior Subordinated Debentures held
by the Trust to the holders of the Trust Securities or (c) upon full payment
of the amounts payable in accordance with the Declaration upon liquidation of
the Trust. Notwithstanding the foregoing, the Preferred Securities
 
                                      10
<PAGE>
 
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of Preferred Securities issued by the Trust must
restore payment of any sums paid under such Preferred Securities or such
Preferred Securities Guarantee.
 
EVENTS OF DEFAULT
 
  An event of default under a Preferred Securities Guarantee will occur upon
the failure of the Company to perform any of its payment or other obligations
thereunder.
 
  The holders of a majority in liquidation amount of the Preferred Securities
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of the Preferred Securities Guarantee or to direct the exercise of any
trust or power conferred upon the Preferred Guarantee Trustee under the
Preferred Securities Guarantee. Any holder of Preferred Securities may
institute a legal proceeding directly against PEPCO to enforce the Preferred
Guarantee Trustee's rights and the obligations of PEPCO under the Preferred
Securities Guarantee, without first instituting a legal proceeding against the
Trust, the Preferred Guarantee Trustee or any other person or entity.
 
STATUS OF THE PREFERRED SECURITIES GUARANTEE
 
  The Preferred Securities Guarantee will constitute an unsecured obligation
of PEPCO and will rank (i) subordinate and junior in right of payment to all
other liabilities of PEPCO, except those made pari passu or subordinate by
their terms, (ii) pari passu with the most senior preferred or preference
stock now or hereafter issued by PEPCO and with any guarantee now or hereafter
entered into by PEPCO in respect of any preferred or preference stock of any
affiliate of PEPCO, and (iii) senior to the Common Stock. The terms of the
Preferred Securities provide that each holder of Preferred Securities by
acceptance thereof agrees to the subordination provisions and other terms of
the Preferred Securities Guarantee relating thereto.
 
  The Preferred Securities Guarantee will constitute a guarantee of payment
and not of collection (that is, the guaranteed party may institute a legal
proceeding directly against PEPCO to enforce its rights under the Preferred
Securities Guarantee without instituting a legal proceeding against any other
person or entity).
 
INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE
 
  The Preferred Guarantee Trustee, prior to the occurrence of a default with
respect to the Preferred Securities Guarantee and after the curing of any such
defaults that may have occurred, undertakes to perform only such duties as are
specifically set forth in such Preferred Securities Guarantee. After such a
default has occurred (of which a responsible officer of the Preferred
Guarantee Trustee has actual knowledge) and is continuing, the Preferred
Guarantee Trustee is required to exercise the rights and powers vested in it
by the Preferred Securities Guarantee using the same degree of care and skill
as a prudent person would exercise or use under the circumstances in the
conduct of his own affairs. Subject to such provisions, the Preferred
Guarantee Trustee is under no obligation to exercise any of the powers vested
in it by the Preferred Securities Guarantee at the request of any holder of
Preferred Securities, unless offered reasonable indemnity against the costs,
expenses and liabilities that might be incurred thereby.
 
  PEPCO and its affiliates maintain certain accounts and other banking
relationships with the Preferred Guarantee Trustee and its affiliates in the
ordinary course of business. The Preferred Guarantee Trustee also serves as
the Debt Trustee and as trustee under other indentures of PEPCO.
 
GOVERNING LAW
 
  The Preferred Securities Guarantee will be governed by and construed in
accordance with the internal laws of the State of New York.

                             PLAN OF DISTRIBUTION
 
  PEPCO and the Trust may sell the Offered Securities in any of, or any
combination of, the following ways: (i) directly to purchasers, (ii) through
agents and (iii) through underwriters or dealers.
 
  Offers to purchase Offered Securities may be solicited directly by PEPCO
and/or the Trust, as the case may be, or by agents designated by PEPCO and/or
the Trust, as the case may be, from time to time. Any such agent, who may be
deemed to be an underwriter as that term is defined in the Securities Act,
involved in the offer or sale of the Offered Securities in respect of which
this Prospectus is delivered will be named, and any commissions payable by
PEPCO to such agent will be set forth, in the Prospectus Supplement. Unless
otherwise indicated in the Prospectus Supplement, any such agent will be
acting on a best efforts basis for the period of its appointment (ordinarily
five business days or less). Agents, dealers and underwriters may be customers
of, engage in transactions with, or perform services for PEPCO in the ordinary
course of business.
 
  If an underwriter or underwriters are utilized in the sale, PEPCO will
execute an underwriting agreement with such underwriters at the time of sale
to them and the names of the underwriters and the terms of the transaction
will be set forth in the Prospectus Supplement, which will be used by the
underwriters to make releases of the Offered Securities in respect of which
this Prospectus is delivered to the public.
 
  If a dealer is utilized in the sale of the Offered Securities in respect of
which this Prospectus is delivered, PEPCO and/or the Trust, as the case may
be, will sell such Offered Securities to the dealer, as principal. The dealer
may then resell such Offered Securities to the public at varying prices to be
determined by such dealer at the time of resale. The name of the dealer and
the terms of the transaction will be set forth in the Prospectus Supplement.
Agents, underwriters, and dealers may be entitled under the relevant
agreements to indemnification by PEPCO and/or the Trust, as the case may be,
against certain liabilities, including liabilities under the Securities Act.
 
  Underwriters, agents or their controlling persons may engage in transactions
with and perform services for PEPCO in the ordinary course of business.

Securities will be passed upon on behalf of the Trust by Skadden, Arps, Slate,

Act, a corporation may indemnify against expenses any directors or officers
made party to a proceeding by reason of his service as such, except in
relation to matters as to which any such director or officer shall be adjudged
to be liable for negligence or misconduct in the performance of duty. Such
indemnification is not exclusive of any other rights to which those
indemnified may be entitled under any by-law, agreement, vote of shareholders
or otherwise.
 
  Under Section 13.1-697 of the Virginia Stock Corporation Act ("VSCA"), a
Virginia corporation may indemnify a director who was, is or is threatened to
be made a party to any proceeding if the director acted in good faith and (i)
he believed, in the case of conduct in his official capacity with the
corporation, that his conduct was in the best interests of the corporation or,
in the case of other conduct, that his conduct was at least not opposed to the
best interests of the corporation, or (ii) in the case of a criminal
proceeding, he had no reasonable cause to believe his conduct was unlawful. A
corporation may not indemnify a director in connection with (i) a proceeding
by or in the right of the corporation in which the director was found liable
to the corporation or (ii) any other proceeding charging improper personal
benefit to him, whether or not involving action in his official capacity, in
which he was adjudged liable on the basis that personal benefit was improperly
received. Indemnification permitted under this section of the VSCA in
connection with a proceeding by or in the right of the corporation is limited
to reasonable expenses incurred in connection with the proceeding.
 
  Under Section 13.1-698, unless limited by its Articles of Incorporation, a
corporation must indemnify against reasonable expenses a director who entirely
prevails in the defense of any proceeding to which he was a party because he
is or was a director of the corporation.
 
  Under Section 13.1-700.1, a court of appropriate jurisdiction, upon the
application of a director, may order a corporation to advance or reimburse
expenses or provide indemnification if the court determines that the director
is so entitled. With respect to a proceeding by or in the right of the
corporation, a court may order indemnification of the director to the extent
of his reasonable expenses even though he was adjudged liable to the
corporation.
 
  Under Section 13.1-699, a corporation may advance reasonable expenses to a
director made a party to a proceeding under certain circumstances, including
the furnishing by the director of (i) a written statement of his good faith
belief that he has met the standard of conduct necessary to obtain
indemnification and (ii) a written undertaking to repay the advance if it is
ultimately determined that he did not meet that standard. Under Section
 
                                     II-1
<PAGE>
 
13.1-702, a corporation may indemnify an officer, employee or agent of a
corporation to the same extent as a director. Under Section 13.1-704, a
corporation may provide indemnification in addition to that provided by
statute if authorized by its Articles of Incorporation, a bylaw made by the
shareholders, or any resolution adopted by the shareholders, except
indemnification against willful misconduct or a knowing violation of the
criminal law.
 
  The By-Laws of the Company provide that the Company shall indemnify each
director or officer and each former director and officer of the Company
against expenses actually and reasonably incurred in connection with the
defense of any action, suit or proceeding by reason of his or her being or
having been such director or officer, including liabilities incurred under the
Securities Act of 1933, as amended, except in relation to matters as to which
such director or officer shall be finally adjudged in such action, suit or
proceeding to have knowingly violated the criminal law or to be liable for
willful misconduct in the performance of his or her duty to the Company; and
that such indemnification shall be in addition to, and not exclusive of, any
other rights to which those indemnified may be entitled under any by-law,
agreement, vote of stockholders, or otherwise.
 
  In the Underwriting Agreement, the underwriters and agents will agree to
indemnify the Company, its directors, officers and controlling persons against
certain civil liabilities that may arise under the Securities Act of 1933 in
connection with this offering.
 
  The Company also has policies of insurance which insure officers and
directors against certain liabilities and expenses incurred by them in such
capacities.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrants hereby undertake:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
 
                                     II-2
<PAGE>
 
      (i) To include any prospectus required in section 10(a)(3) of the
    Securities Act of 1933 (the "1933 Act");
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement;
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;
 
  provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
  information required to be included in a post-effective amendment by those
  paragraphs is contained in periodic reports filed with or furnished to the
  Commission by the Company pursuant to section 13 or section 15(d) of the
  Securities Exchange Act of 1934 that are incorporated by reference in this
  Registration Statement;
 
    (2) That, for the purpose of determining any liability under the 1933
  Act, each such post-effective amendment shall be deemed to be a new
  registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof; and
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
  (b) The undersigned Registrants hereby undertake that for purposes of
determining any liability under the 1933 Act, each filing of the Company's
annual report pursuant to section 13(a) or 15(d) of the Securities Exchange
Act of 1934 that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  (c) Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the provisions described under Item 15 above, or
otherwise, the Registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the 1933 Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
the payment by the Registrants of expenses incurred or paid by a director,
officer or controlling person of the Registrants in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrants will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.
 
  (d) The undersigned Registrants hereby undertake that:
 
    (1) For purposes of determining any liability under the 1933 Act, the
  information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrants pursuant to Rule 424(b)(1) or (4)
  under the Securities Act shall be deemed to be part of this Registration
  Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the 1933 Act, each
  post-effective amendment that contains a form of prospectus shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

          (b)  An Indemnified Person shall be fully protected in relying in good
               faith upon the records of the Trust and upon such information,
               opinions, reports or statements presented to the Trust by any
               Person as to matters the Indemnified Person reasonably believes
               are within such other Person's professional or expert competence
               and who has been selected with reasonable care by or on behalf of
               the Trust, including information, opinions, reports or statements
               as to the value and amount of the assets, liabilities, profits,
               losses, or any other facts pertinent to the existence and amount
               of assets from which distributions to holders of Securities might
               properly be paid.

     SECTION 4.2  Fiduciary Duty.

          (a)  To the extent that, at law or in equity, an Indemnified Person
               has duties (including fiduciary duties) and liabilities relating
               thereto to the Trust or to any Covered Person, an Indemnified
               Person acting under this Declaration shall not be liable to the
               Trust or to any Covered Person for its good faith reliance on the
               provisions of this Declaration.  The provisions of this
               Declaration, to the extent that they restrict the duties and
               liabilities of an Indemnified Person otherwise existing at law or
               in equity, are agreed by the parties hereto to replace such other
               duties and liabilities of such Indemnified Person;

          (b)  Unless otherwise expressly provided herein:
 
               (i)  whenever a conflict of interest exists or arises between
                    Covered Persons; or

               (ii) whenever this Declaration or any other agreement
                    contemplated herein or therein provides that an Indemnified
                    Person shall act in a manner that is, or provides terms that
                    are, fair and reasonable to the Trust or any holder of
                    Securities, the Indemnified Person shall resolve such
                    conflict of interest, take such action or provide such
                    terms, considering in each case the relative interest of
                    each party (including its own interest) to such conflict,
                    agreement, transaction or situation and the benefits and
                    burdens relating to such interests, any customary or
                    accepted industry practices, and any applicable generally
                    accepted accounting practices or principles.  In the absence
                    of bad faith by the Indemnified Person, the resolution,
                    action or term so made, taken or provided by the Indemnified
                    Person shall not constitute a breach of this Declaration or
                    any other agreement contemplated herein or of any duty or
                    obligation of the Indemnified Person at law or in equity or
                    otherwise; and

                                       9
<PAGE>
 
          (c)  Whenever in this Declaration an Indemnified Person is permitted
               or required to make a decision:

               (i)  in its "discretion" or under a grant of similar authority,
                    the Indemnified Person shall be entitled to consider such
                    interests and factors as it desires, including its own
                    interests, and shall have no duty or obligation to give any
                    consideration to any interest of or factors affecting the
                    Trust or any other Person; or

               (ii) in its "good faith" or under another express standard, the
                    Indemnified Person shall act under such express standard and
                    shall not be subject to any other or different standard
                    imposed by this Declaration or by applicable law.

     SECTION 4.3  Indemnification.

          (a)  (i)  The Debenture Issuer shall indemnify, to the full extent
                     permitted by law, any Company Indemnified Person who was or
                     is a party or is threatened to be made a party to any
                     threatened, pending or completed action, suit or
                     proceeding, whether civil, criminal, administrative or
                     investigative (other than an action by or in the right of
                     the Trust) by reason of the fact that he is or was a
                     Company Indemnified Person against expenses (including 
                     attorneys' fees), judgments, fines and amounts paid in
                     settlement actually and reasonably incurred by him in
                     connection with such action, suit or proceeding if he acted
                     in good faith and in a manner he reasonably believed to be
                     in or not opposed to the best interests of the Trust, and,
                     with respect to any criminal action or proceeding, had no
                     reasonable cause to believe his conduct was unlawful.  The
                     termination of any action, suit or proceeding by judgment,
                     order, settlement, conviction, or upon a plea of nolo
                     contendere or its equivalent, shall not, of itself, create
                     a presumption that the Company Indemnified Person did not
                     act in good faith and in a manner which he reasonably
                     believed to be in or not opposed to the best interests of
                     the Trust, and, with respect to any criminal action or
                     proceeding, had reasonable cause to believe that his
                     conduct was unlawful.

               (ii)  The Debenture Issuer shall indemnify, to the full extent
                     permitted by law, any Company Indemnified Person who was or
                     is a party or is threatened to be made a party to any

                                       10
<PAGE>
 
                     threatened, pending or completed action or suit by or in
                     the right of the Trust to procure a judgment in its favor
                     by reason of the fact that he is or was a Company
                     Indemnified Person against expenses (including attorneys'
                     fees) actually and reasonably incurred by him in connection
                     with the defense or settlement of such action or suit if he
                     acted in good faith and in a manner he reasonably believed
                     to be in or not opposed to the best interests of the Trust
                     and except that no such indemnification shall be made in
                     respect of any claim, issue or matter as to which such
                     Company Indemnified Person shall have been adjudged to be
                     liable to the Trust unless and only to the extent that the
                     Court of Chancery of Delaware or the court in which such
                     action or suit was brought shall determine upon application
                     that, despite the adjudication of liability but in view of
                     all the circumstances of the case, such person is fairly
                     and reasonably entitled to indemnity for such expenses
                     which such Court of Chancery or such other court shall deem
                     proper.

               (iii) To the extent that a Company Indemnified Person shall be
                     successful on the merits or otherwise (including dismissal
                     of an action without prejudice or the settlement of an
                     action without admission of liability) in defense of any
                     action, suit or proceeding referred to in paragraphs (i)
                     and (ii) of this Section 4.3(a), or in defense of any
                     claim, issue or matter therein, he shall be indemnified, to
                     the full extent permitted by law, against expenses
                     (including attorneys' fees) actually and reasonably
                     incurred by him in connection therewith.

               (iv)  Any indemnification under paragraphs (i) and (ii) of this
                     Section 4.3(a) (unless ordered by a court) shall be made by
                     the Debenture Issuer only as authorized in the specific
                     case upon a determination that indemnification of the
                     Company Indemnified Person is proper in the circumstances
                     because he has met the applicable standard of conduct set
                     forth in paragraphs (i) and (ii).  Such determination shall
                     be made (1) by the Regular Trustees by a majority vote of a
                     quorum consisting of such Regular Trustees who were not
                     parties to such action, suit or proceeding, (2) if such a
                     quorum is not obtainable, or, even if obtainable, if a
                     quorum of disinterested Regular Trustees so directs, by
                     independent legal counsel in a written opinion, or (3) by
                     the holder of the Common Security.

               (v)   Expenses (including attorneys' fees) incurred by a Company

                                       11
<PAGE>
 
                     Indemnified Person in defending a civil, criminal,
                     administrative or investigative action, suit or proceeding
                     referred to in paragraphs (i) and (ii) of this Section
                     4.3(a) shall be paid by the Debenture Issuer in advance of
                     the final disposition of such action, suit or proceeding
                     upon receipt of an undertaking by or on behalf of such
                     Company Indemnified Person to repay such amount if it shall
                     ultimately be determined that he is not entitled to be
                     indemnified by the Debenture Issuer as authorized in this
                     Section 4.3(a).  Notwithstanding the foregoing, no advance
                     shall be made by the Debenture Issuer if a determination is
                     reasonably and promptly made (i) by the Regular Trustees by
                     a majority vote of a quorum of disinterested Regular
                     Trustees, (ii) if such a quorum is not obtainable, or, even
                     if obtainable, if a quorum of disinterested Regular
                     Trustees so directs, by independent legal counsel in a
                     written opinion or (iii) the holder of the Common Security
                     that, based upon the facts known to the Regular Trustees,
                     counsel or the holder of the Common Security at the time
                     such determination is made, such Company Indemnified Person
                     acted in bad faith or in a manner that such person did not
                     believe to be in or not opposed to the best interests of
                     the Trust, or, with respect to any criminal proceeding,
                     that such Company Indemnified Person believed or had
                     reasonable cause to believe his conduct was unlawful.  In
                     no event shall any advance be made in instances where the
                     Regular Trustees, independent legal counsel or holder of
                     the Common Security reasonably determine that such person
                     deliberately breached his duty to the Trust or its Common
                     or Preferred Security Holders.

               (vi)  The indemnification and advancement of expenses provided
                     by, or granted pursuant to, the other paragraphs of this
                     Section 4.3(a) shall not be deemed exclusive of any other
                     rights to which those seeking indemnification and
                     advancement of expenses may be entitled under any
                     agreement, vote of stockholders or disinterested directors
                     of the Debenture Issuer or holders of the Preferred
                     Security or otherwise, both as to action in his official
                     capacity and as to action in another capacity while holding
                     such office.  All rights to indemnification under this
                     Section 4.3(a) shall be deemed to be provided by a contract
                     between the Debenture Issuer and each Company Indemnified
                     Person who serves in such capacity at any time while this
                     Section 4.3(a) is in effect.  Any repeal or modification of
                     this Section 4.3(a) shall not affect any rights or
                     obligations then existing.

               (vii) The Debenture Issuer or the Trust may purchase and
                     maintain insurance on behalf of any person who is or was a
                     Company Indemnified Person against any liability asserted
                     against him and incurred by him in any such capacity, or
                     arising out of his status as such, whether or not the
                     Debenture Issuer would have the power to indemnify him
                     against such liability under the provisions of this Section
                     4.3(a).

               (viii)For purposes of this Section 4.3(a), references to "the
                     Trust" shall include, in addition to the resulting or
                     surviving entity, any constituent entity (including any
                     constituent of a constituent) absorbed in a consolidation
                     or merger, so that any person who is or was a director,
                     trustee, officer or employee of such constituent entity, or
                     is or was serving at the request of such constituent entity
                     as a director, trustee, officer, employee or agent of
                     another entity, shall stand in the same position under the
                     provisions of this Section 4.3(a) with respect to the
                     resulting or surviving entity as he would have with respect
                     to such constituent entity if its separate existence had
                     continued.

               (ix)  The indemnification and advancement of expenses provided
                     by, or granted pursuant to, this Section 4.3(a) shall,
                     unless otherwise provided when authorized or ratified,
                     continue as to a person who has ceased to be a Company
                     Indemnified Person and shall inure to the benefit of the
                     heirs, executors and administrators of such a person.

          (b)  The Debenture Issuer agrees to indemnify (i) the Delaware
               Trustee, (ii) any Affiliate of the Delaware Trustee, and (iii)
               any officers, directors, shareholders, members, partners,
               employees, representatives, nominees, custodians or agents of the
               Delaware Trustee (each of the Persons in (i) through (iii) being
               referred to as a "Fiduciary Indemnified Person") for, and to hold
               each Fiduciary Indemnified Person harmless against, any loss,
               liability or expense incurred without negligence or bad faith on
               its part, arising out of or in connection with the acceptance or
               administration of the trust or trusts hereunder, including the
               costs and expenses (including reasonable legal fees and expenses)
               of defending itself against, or investigating, any claim or
               liability in connection with the exercise or performance of any
               of its powers or duties hereunder. The obligation to indemnify as
               set forth in this Section 4.3(b) shall survive the termination of
               this Declaration.

     SECTION 4.4  Outside Businesses.

     Any Covered Person, the Sponsor and the Delaware Trustee may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the holders of Securities shall have no rights by
virtue of this Declaration in and to such independent ventures or the income or
profits derived therefrom and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper.  No Covered Person, the Sponsor or the Delaware Trustee shall be
obligated to present any particular investment or other opportunity to the Trust
even if such opportunity is of a character that, if presented to the Trust,
could be taken by the Trust, and any Covered Person, the Sponsor and the
Delaware Trustee shall have the right to take for its own account (individually
or as a partner or fiduciary) or to recommend to others any such particular
investment or other opportunity. Any Covered Person and the Delaware Trustee may
engage or be interested in any financial or other transaction with the Sponsor
or any Affiliate of the Sponsor, or may act as depositary for, trustee or agent
for or may act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.
