                       ABOUT THIS PROSPECTUS SUPPLEMENT

   This document is in two parts. The first part is this prospectus supplement,
which describes the specific terms of this notes offering. The second part, the
accompanying prospectus, gives more general information, some of which may not
apply to this offering.

   If the description of the offering varies between this prospectus supplement
and the accompanying prospectus, you should rely on the information in this
prospectus supplement.

   Unless we have indicated otherwise, or the context otherwise requires,
references in this prospectus supplement and the accompanying prospectus to
"Duke Capital," "we," "us" and "our" or similar terms are to Duke Capital
Corporation and its subsidiaries.

                          FORWARD-LOOKING STATEMENTS

   This prospectus supplement and the accompanying prospectus contain or
incorporate by reference statements that do not directly or exclusively relate
to historical facts. Such statements are "forward-looking statements" within
the meaning of the Private Securities Litigation Reform Act of 1995. You can
typically identify forward-looking statements because they include or are
preceded by forward-looking words, such as "may," "will," "could," "project,"
"believe," "anticipate," "expect," "estimate," "continue," "potential," "plan,"
"forecast" and the like. Those statements represent our intentions, plans,
expectations, assumptions and beliefs about future events and are subject to
risks, uncertainties and other factors. Many of those factors are outside our
control and could cause actual results to differ materially from the results
expressed or implied by those forward-looking statements. Some of the factors
that could cause such differences are:

   . state, federal and foreign legislative and regulatory initiatives that
     affect cost and investment recovery, have an impact on rate structures and
     affect the speed at and degree to which competition enters the natural gas
     industry;

   . industrial, commercial and residential growth in the service territories
     of our subsidiaries;

   . the weather and other natural phenomena;

   . the timing and extent of changes in commodity prices, interest rates and
     foreign currency exchange rates;

   . changes in environmental and other laws and regulations to which our
     subsidiaries are subject or other external factors over which we have no
     control;

   . the results of financing efforts, including our ability to obtain
     financing on favorable terms, which can be affected by various factors,
     including our credit ratings and general economic conditions;

   . the level of creditworthiness of counterparties to our transactions;

   . growth in opportunities for our subsidiaries; and

   . the effect of accounting policies issued periodically by accounting
     standard-setting bodies.

   In light of these risks, uncertainties and assumptions, the forward-looking
events referred to in this prospectus supplement and the accompanying
prospectus might not occur. Neither we nor the underwriters undertake any
obligation to publicly update or revise any forward-looking statements, whether
as a result of new information, future events or otherwise.

                           DESCRIPTION OF THE NOTES

General

   The following description of the terms of the   % Senior Notes and the   %
Senior Notes summarizes certain general terms that will apply to the Notes. The
Notes will be issued under a Senior Indenture between us and JPMorgan Chase
Bank (formerly known as The Chase Manhattan Bank), as trustee, dated as of
April 1, 1998, as supplemented from time to time (the "Senior Indenture"). This
description is not complete and should be read together with the description of
the general terms and provisions of Senior Notes provided under the caption
"Description of the Senior Notes" in the accompanying prospectus. Defined terms
have the meanings assigned to them in the Senior Indenture.

   The Notes will be issuable in denominations of $1,000 and integral multiples
of $1,000 in excess thereof. The   % Senior Notes will be issued in an
aggregate principal amount of $500,000,000. The   % Senior Notes will be issued
in an aggregate principal amount of $250,000,000.

   We may from time to time, without the consent of existing holders, create
and issue further Notes having the same terms and conditions as the Notes being
offered hereby in all respects, except for issue date, issue price and, if
applicable, the first payment of interest thereon. Additional Notes issued in
this manner will be consolidated with and will form a single series with the
previously outstanding Notes of like tenor.

   As used in this prospectus supplement, Business Day means, with respect to
any note, a day other than (i) a Saturday or a Sunday, (ii) a day on which
banking institutions in New York City are authorized or obligated by law or
executive order to remain closed or (iii) a day on which the corporate trust
office of the trustee is closed for business.

Ranking

   The Notes will be our direct, unsecured and unsubordinated obligations. The
Notes will rank equal in priority with all of our existing and future unsecured
and unsubordinated indebtedness and senior in right of payment to all of our
existing and future subordinated debt. Our Senior Indenture contains no
restrictions on the amount of additional indebtedness that we may issue under
it.

Interest on the   % Senior Notes

   Each   % Senior Note will mature on February    , 2013 and will bear
interest at the rate of   % per year from the date of original issuance. We
will pay interest semiannually on            and            of each year,
beginning           , 2002 to the person in whose name the   % Senior Note is
registered at the close of business on the fifteenth calendar day (whether or
not a Business Day) before the relevant interest payment date, except that we
will pay interest payable at the maturity date of the   % Senior Notes or on a
redemption date to the person or persons to whom principal is payable. The
amount of interest payable will be computed on the basis of a 360-day year of
twelve 30-day months. If any date on which interest is payable is not a
Business Day, we will pay that interest on the next Business Day without any
interest or other payment due to the delay.

Interest on the   % Senior Notes

   Each   % Senior Note will mature on February    , 2032 and will bear
interest at the rate of   % per year from the date of original issuance. We
will pay interest semi-annually on            and            of each year,
beginning           , 2002 to the person in whose name the   % Senior Note is
registered at the close of business on the fifteenth calendar day (whether or
not a Business Day) before the relevant interest payment date, except that we
will pay interest payable at the maturity date of the   % Senior Notes or on a
redemption date to

                                      S-6



the person or persons to whom principal is payable. The amount of interest
payable will be computed on the basis of a 360-day year of twelve 30-day
months. If any date on which interest is payable is not a Business Day, we will
pay that interest on the next Business Day without any interest or other
payment due to the delay.

Optional Redemption

   We will have the right to redeem the Notes, in whole or in part at any time,
at a redemption price equal to the greater of (1) 100% of the principal amount
of the   % Senior Notes or the   % Senior Notes to be redeemed and (2) the sum
of the present values of the remaining scheduled payments of principal and
interest on such notes (exclusive of interest accrued to the redemption date)
discounted to the redemption date on a semiannual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus    basis
points in the case of the    % Senior Notes and     basis points in the case of
the    % Senior Notes, plus, in either case, accrued and unpaid interest on the
principal amount being redeemed to such redemption date.

   "Treasury Rate" means, with respect to any redemption date, (1) the yield,
under the heading which represents the average for the immediately preceding
week, appearing in the most recently published statistical release designated
"H.15(519)" or any successor publication which is published weekly by the Board
of Governors of the Federal Reserve System and which establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity
corresponding to the Comparable Treasury Issue (if no maturity is within three
months before or after the maturity date of the notes to be redeemed, yields
for the two published maturities most closely corresponding to the Comparable
Treasury Issue shall be determined, and the Treasury Rate shall be interpolated
or extrapolated from such yields on a straight-line basis, rounding to the
nearest month) or (2) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain
such yields, the rate per year equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date. The Treasury
Rate will be calculated on the third Business Day preceding the redemption date.

   "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable
to the remaining term of the notes to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such notes.

   "Independent Investment Banker" means either Banc One Capital Markets, Inc.
or Barclays Capital Inc. or any successor firm or, if either such firm is
unwilling or unable to select the Comparable Treasury Issue, an independent
investment banking institution of national standing appointed by the trustee
after consultation with us.

   "Comparable Treasury Price" means with respect to any redemption date for
notes, (1) the average of four Reference Treasury Dealer Quotations for such
redemption date, after excluding the highest and lowest such Reference Treasury
Quotations, or (2) if the trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such quotations.

   "Reference Treasury Dealer" means (i) each of Banc One Capital Markets, Inc.
and Barclays Capital Inc., and their respective successors; provided, however,
that if any of the foregoing shall cease to be a primary U.S. Government
securities dealer in New York City (a "Primary Treasury Dealer"), we will
substitute therefor another Primary Treasury Dealer and (ii) up to two other
Primary Treasury Dealers selected by us.

   "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
trustee, of the bid and asked prices for the Comparable

                                      S-7



Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the trustee by such Reference Treasury Dealer at 5:00
p.m., New York City time, on the third Business Day preceding such redemption
date.

Redemption Procedures

   We will provide not less than 30 nor more than 60 days' notice mailed to
each registered holder of the Notes to be redeemed. If the redemption notice is
given and funds deposited as required, then interest will cease to accrue on
and after the redemption date on the notes or portions of such notes called for
redemption. In the event that any redemption date is not a Business Day, we
will pay the redemption price on the next Business Day without any interest or
other payment due to the delay.

Sinking Fund

   There is no provision for a sinking fund applicable to the Notes.

Defeasance and Covenant Defeasance

   The Notes will be subject to defeasance and covenant defeasance as described
in the Senior Indenture. See "Description of the Senior Notes--Defeasance and
Covenant Defeasance" in the accompanying prospectus.

   Under current United States federal income tax law, a defeasance would be
treated as an exchange of the relevant Notes in which holders of such Notes
might recognize gain or loss. In addition, the amount, timing and character of
amounts that holders would thereafter be required to include in income might be
different from that which would be includible in the absence of that
defeasance. We urge investors to consult their own tax advisors as to the
specific consequences of a defeasance, including the applicability and effect
of tax laws other than United States federal income tax laws.

   Under current United States federal income tax law, unless accompanied by
other changes in the terms of the Notes, covenant defeasance should not be
treated as a taxable exchange.

Book-Entry Only Issuance--The Depository Trust Company

   The Depository Trust Company ("DTC") will act as the initial securities
depositary for the Notes. The Notes will be issued only as fully registered
securities registered in the name of Cede & Co., DTC's nominee. One or more
fully registered global certificates for the   % Senior Notes and the   %
Senior Notes will be issued, representing in the aggregate the total principal
amount of   % Senior Notes and   % Senior Notes, and will be deposited with DTC
or its custodian.

   The following is based on information furnished to us by DTC:

   DTC is a limited-purpose trust company organized under the laws of the State
   of New York, a member of the Federal Reserve System, a "clearing
   corporation" within the meaning of the New York Uniform Commercial Code and
   a "clearing agency" registered pursuant to the provisions of Section 17A of
   the Securities Exchange Act of 1934. DTC was created to hold securities of
   its participants ("participants") and to facilitate the clearance and
   settlement of securities transactions among its participants in these
   securities through electronic book-entry changes in accounts of the
   participants, thereby eliminating the need for physical movement of
   securities certificates. DTC's participants include securities brokers and
   dealers (including the underwriters), banks, trust companies, clearing
   corporations and certain other organizations, some of whom (and/or their
   representatives) own DTC. Persons who are not participants may beneficially
   own securities held by DTC only through participants.

                                      S-8



   DTC is owned by a number of its direct participants and by the New York
   Stock Exchange, Inc., the American Stock Exchange LLC and the National
   Association of Securities Dealers, Inc. Access to DTC's system is also
   available to others including securities brokers and dealers, banks and
   trust companies that clear through or maintain a custodial relationship with
   a direct participant, either directly or indirectly ("indirect
   participants"). The rules applicable to DTC and its participants are on file
   with the SEC.

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

   DTC has no knowledge of the actual beneficial owners of the Notes. DTC's
   records reflect only the identity of the direct participants to whose
   accounts the Notes are credited, which may or may not be the beneficial
   owners. The participants will remain responsible for keeping account of
   their holdings on behalf of their customers.

   Conveyance of notices and other communications by DTC to direct
   participants, by direct participants to indirect participants, and by direct
   participants and indirect participants to beneficial owners will be governed
   by arrangements among them, subject to any statutory or regulatory
   requirements as may be in effect from time to time.

   Although voting with respect to the Notes is limited, in those cases where a
   vote is required, neither DTC nor Cede & Co. will itself consent or vote
   with respect to the Notes. Under its usual procedures, DTC would mail an
   omnibus proxy to us as soon as possible after the record date. The omnibus
   proxy assigns Cede & Co.'s consenting or voting rights to those direct
   participants to whose accounts the Notes are credited on the record date
   (identified in a listing attached to the omnibus proxy).

   Payments on the Notes will be made to DTC in immediately available funds.
   DTC's practice is to credit direct participants' accounts on the relevant
   payment date in accordance with their respective holdings shown on DTC's
   records unless DTC has reason to believe that it will not receive payments
   on the relevant payment date. Payments by participants to beneficial owners
   will be governed by standing instructions and customary practices, as is the
   case with securities held for the account of customers in bearer form or
   registered in "street name," and will be the responsibility of the
   participant and not our responsibility or the responsibility of DTC, subject
   to any statutory or regulatory requirements as may be in effect from time to
   time. Payment to DTC is our responsibility, disbursement of the payments to
   direct participants is the responsibility of DTC, and disbursement of the
   payments to the beneficial owners is the responsibility of direct and
   indirect participants.

   Except as provided in this prospectus supplement, a beneficial owner of   %
   Senior Notes and   % Senior Notes will not be entitled to receive physical
   delivery of   % Senior Notes and   % Senior Notes. Accordingly, each
   beneficial owner must rely on the procedures of DTC to exercise any rights
   under the   % Senior Notes or the   % Senior Notes. The laws of some
   jurisdictions require that certain purchasers of securities take physical
   delivery of securities in definitive form. These laws may impair the ability
   to transfer beneficial interests in a global   % Senior Note or a global   %
   Senior Note.

                                      S-9



   DTC may discontinue providing its services as securities depositary with
   respect to the Notes at any time by giving reasonable notice to us. Under
   those circumstances, in the event that a successor securities depositary is
   not obtained,   % Senior Note and   % Senior Note certificates will be
   printed and delivered to the holders of record. Additionally, we may decide
   to discontinue use of the system of book-entry transfers through DTC (or a
   successor depositary) with respect to the Notes. In that event, certificates
   for the   % Senior Notes and the   % Senior Notes will be printed and
   delivered to the holders of record.

   We have no responsibility for the performance by DTC or its participants of
their respective obligations as described in this prospectus supplement or
under the rules and procedures governing their respective operations.

                                                    ============     ============


   In this underwriting agreement, the underwriters have agreed, subject to
certain conditions, to purchase all of the Notes if any of the Notes are
purchased.

   The underwriters propose initially to offer the Notes to the public at the
initial public offering price set forth on the cover page of this prospectus
supplement, and to certain dealers at that price less a concession not in
excess of $      per    % Senior Note and $      per    % Senior Note. The
underwriters may allow, and those dealers may reallow, a discount not in excess
of $      per    % Senior Note and $      per    % Senior Note to certain other
dealers. The initial public offering price, selling concession and discount may
be changed after the initial public offering.

   The    % Senior Notes and the    % Senior Notes are each a new issue of
securities with no established trading market. The underwriters have advised us
that they intend to make a market in the Notes but are not obligated to do so
and may discontinue market-making at any time without notice. Neither we nor
the underwriters can provide any assurances as to the liquidity of the trading
market for the    % Senior Notes or the    % Senior Notes.

   The underwriters may purchase and sell the Notes in the open market in
connection with the offering. Those transactions may include over-allotment and
stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Notes. Syndicate short positions involve the sale by
the underwriters of a greater number of Notes than they are required to
purchase from us in the offering. The underwriters also may impose a penalty
bid, by which selling concessions allowed to syndicate members or other broker
dealers with respect to the securities sold in the offering for their account
may be reclaimed by the syndicate if those Notes are repurchased by the
syndicate in stabilizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the Notes, which
may be higher than the price that might otherwise prevail in the open market.
These activities, if commenced, may be discontinued at any time.

   The underwriters have agreed to reimburse our offering expenses and will
make an additional payment to us of $    .

   We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933.

   Certain of the underwriters and their affiliates engage in transactions
with, and, from time to time, have performed services for us or for certain of
our affiliates in the ordinary course of business and may do so in the future.

                             VALIDITY OF THE NOTES

   Simpson Thacher & Bartlett, New York, New York will issue an opinion about
the validity of the Notes and certain related matters on behalf of Duke
Capital. Sidley Austin Brown & Wood LLP will pass upon the validity of the
Notes for the underwriters.

                                USE OF PROCEEDS

   Each Trust will invest the proceeds it receives from the sale of the
Preferred Securities in Junior Subordinated Notes. Unless the applicable
prospectus supplement states otherwise, Duke Capital will use the net proceeds
that it receives from such investment and any proceeds that it receives from
sales of its Senior Notes or other sales of the Junior Subordinated Notes for
general corporate purposes, including capital expenditures, working capital,
debt repayments and advances to affiliates.

   If Duke Capital does not use the proceeds of the Senior Notes or the Junior
Subordinated Notes, or the net proceeds of the Preferred Securities,
immediately, it may temporarily invest them in short-term interest-bearing
obligations or deposit them with banks.

                                  THE TRUSTS

   Duke Capital formed each Trust as a statutory business trust under Delaware
law. Each Trust's business is defined in a trust agreement executed by Duke
Capital, as depositor, and Chase Manhattan Bank USA, National Association. Each
trust agreement will be amended when Preferred Securities are issued under it
and will be in substantially the form filed as an exhibit to the registration
statement, of which this prospectus is a part. An amended trust agreement is
called a "Trust Agreement" in this prospectus.

   The Preferred Securities and the Common Securities of each Trust represent
undivided beneficial interests in the assets of that Trust. The Preferred
Securities and the Common Securities together are sometimes called the "Trust
Securities" in this prospectus.

   The trustees of each Trust will conduct that Trust's business and affairs.
Duke Capital, as the holder of the Common Securities of each Trust, will
appoint the trustees of that Trust. The trustees of each Trust will consist of:

   . two officers of Duke Capital as Administrative Trustees;

   . The Chase Manhattan Bank as Property Trustee; and

   . Chase Manhattan Bank USA, National Association as Delaware Trustee.

   The prospectus supplement relating to the Preferred Securities of a Trust
will provide further information concerning that Trust.

   No separate financial statements of any Trust are included in this
prospectus. Duke Capital considers that such statements would not be material
to holders of the Preferred Securities because no Trust has any independent
operations and the sole purpose of each Trust is investing the proceeds of the
sale of its Trust Securities in Junior Subordinated Notes. Duke Capital does
not expect that any of the Trusts will be filing annual, quarterly or special
reports with the SEC.

   The principal place of business of each Trust will be c/o Duke Capital
Corporation, 526 South Church Street, Charlotte, North Carolina 28202,
telephone (704) 594-6200.

                                      4



                             ACCOUNTING TREATMENT

   Each Trust will be treated as a subsidiary of Duke Capital for financial
reporting purposes. Accordingly, Duke Capital's consolidated financial
statements will include the accounts of each Trust. The Preferred Securities,
along with other trust preferred securities that Duke Capital guarantees on an
equivalent basis, will be presented as a separate line item in Duke Capital's
consolidated balance sheets, entitled "Guaranteed Preferred Beneficial
Interests in Subordinated Notes of Duke Capital Corporation." Duke Capital will
record distributions that each Trust pays on the Preferred Securities as an
expense in its consolidated statement of income.

                        DESCRIPTION OF THE SENIOR NOTES

   Duke Capital will issue the Senior Notes in one or more series under its
Senior Indenture dated as of April 1, 1998 between Duke Capital and The Chase
Manhattan Bank, as Trustee, as supplemented from time to time. The Senior
Indenture is an exhibit to the registration statement, of which this prospectus
is a part.

   The Senior Notes are unsecured and unsubordinated obligations and will rank
equally with all of Duke Capital's other unsecured and unsubordinated
indebtedness.

   Duke Capital conducts its business through subsidiaries. Accordingly, its
ability to meet its obligations under the Senior Notes is dependent on the
earnings and cash flows of those subsidiaries and the ability of those
subsidiaries to pay dividends or to advance or repay funds to Duke Capital. In
addition, the rights that Duke Capital and its creditors would have to
participate in the assets of any such subsidiary upon the subsidiary's
liquidation or recapitalization will be subject to the prior claims of the
subsidiary's creditors. Certain subsidiaries of Duke Capital have incurred
substantial amounts of debt in the expansion of their businesses, and Duke
Capital anticipates that certain of its subsidiaries will do so in the future.

   The following description of the Senior Notes is only a summary and is not
intended to be comprehensive. For additional information you should refer to
the Senior Indenture.

General

   The Senior Indenture does not limit the amount of Senior Notes that Duke
Capital may issue under it. Duke Capital may issue Senior Notes from time to
time under the Senior Indenture in one or more series by entering into
supplemental indentures or by its Board of Directors or a duly authorized
committee authorizing the issuance. The form of supplemental indenture to the
Senior Indenture is an exhibit to the registration statement, of which this
prospectus is a part.

   The Senior Notes of a series need not be issued at the same time, bear
interest at the same rate or mature on the same date.

   The Senior Indenture does not protect the holders of Senior Notes if Duke
Capital engages in a highly leveraged transaction.

Provisions Applicable to Particular Series

     dollars;

   . if payments may be made, at Duke Capital's election or at the holder's
     election, in a currency other than that in which the Senior Notes are
     stated to be payable, then the currency in which those payments may be
     made, the terms and conditions of the election and the manner of
     determining those amounts;

   . the portion of the principal payable upon acceleration of maturity, if
     other than the entire principal;

   . whether the Senior Notes will be issuable as global securities and, if so,
     the securities depositary;

   . any changes in the events of default or covenants with respect to the
     Senior Notes;

   . any index or formula used for determining principal, premium or interest;

   . if the principal payable on the maturity date will not be determinable on
     one or more dates prior to the maturity date, the amount which will be
     deemed to be such principal amount or the manner of determining it; and

   . any other terms.

   Unless Duke Capital states otherwise in the applicable prospectus
supplement, Duke Capital will issue the Senior Notes only in fully registered
form without coupons, and there will be no service charge for any registration
of transfer or exchange of the Senior Notes. Duke Capital may, however, require
payment to cover any tax or other governmental charge payable in connection
with any transfer or exchange. Subject to the terms of the Senior Indenture and
the limitations applicable to global securities, transfers and exchanges of the
Senior Notes may be made at The Chase Manhattan Bank, 55 Water Street, New
York, New York 10041 or at any other office maintained by Duke Capital for such
purpose.

   The Senior Notes will be issuable in denominations of $1,000 and any
integral multiples of $1,000, unless Duke Capital states otherwise in the
applicable prospectus supplement.

   Duke Capital may offer and sell the Senior Notes, including original issue
discount Senior Notes, at a substantial discount below their principal amount.
The applicable prospectus supplement will describe special United States
federal income tax and any other considerations applicable to those securities.
In addition, the applicable prospectus supplement may describe certain special
United States federal income tax or other considerations, if any, applicable to
any Senior Notes that are denominated in a currency other than U.S. dollars.

                                      6



Global Securities

   Duke Capital may issue some or all of the Senior Notes as book-entry
securities. Any such book-entry securities will be represented by one or more
fully registered global certificates. Duke Capital will register each global
security with or on behalf of a securities depositary identified in the
applicable prospectus supplement. Each global security will be deposited with
the securities depositary or its nominee or a custodian for the securities
depositary.

   As long as the securities depositary or its nominee is the registered holder
of a global security representing Senior Notes, that person will be considered
the sole owner and holder of the global security and the Senior Notes it
represents for all purposes. Except in limited circumstances, owners of
beneficial interests in a global security:

   . may not have the global security or any Senior Notes it represents
     registered in their names;

   . may not receive or be entitled to receive physical delivery of
     certificated Senior Notes in exchange for the global security; and

   . will not be considered the owners or holders of the global security or any
     Senior Notes it represents for any purposes under the Senior Notes or the
     Senior Indenture.

   Duke Capital will make all payments of principal and any premium and
interest on a global security to the securities depositary or its nominee as
the holder of the global security. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of securities in
definitive form. These laws may impair the ability to transfer beneficial
interests in a global security.

   Ownership of beneficial interests in a global security will be limited to
institutions having accounts with the securities depositary or its nominee,
which are called "participants" in this discussion, and to persons that hold
beneficial interests through participants. When a global security representing
Senior Notes is issued, the securities depositary will credit on its book
entry, registration and transfer system the principal amounts of Senior Notes
the global security represents to the accounts of its participants. Ownership
of beneficial interests in a global security will be shown only on, and the
transfer of those ownership interests will be effected only through, records
maintained by:

   . the securities depositary, with respect to participants' interests; and

   . any participant, with respect to interests the participant holds on behalf
     of other persons.

   Payments participants make to owners of beneficial interests held through
those participants will be the responsibility of those participants. The
securities depositary may from time to time adopt various policies and
procedures governing payments, transfers, exchanges and other matters relating
to beneficial interests in a global security. None of the following will have
any responsibility or liability for any aspect of the securities depositary's
or any participant's records relating to beneficial interests in a global
security representing Senior Notes, for payments made on account of those
beneficial interests or for maintaining, supervising or reviewing any records
relating to those beneficial interests:

   . Duke Capital;

   . the Senior Indenture Trustee; or

   . an agent of either of the above.

Redemption

   Provisions relating to the redemption of Senior Notes will be set forth in
the applicable prospectus supplement. Unless Duke Capital states otherwise in
the applicable prospectus supplement, Duke Capital may

                                      7



redeem Senior Notes only upon notice mailed at least 30 but not more than 60
days before the date fixed for redemption. Unless Duke Capital states otherwise
in the applicable prospectus supplement, that notice may state that the
redemption will be conditional upon the Senior Indenture Trustee, or the
applicable paying agent, receiving sufficient funds to pay the principal,
premium and interest on those Senior Notes on the date fixed for redemption and
that if the Senior Indenture Trustee or the applicable paying agent does not
receive those funds, the redemption notice will not apply, and Duke Capital
will not be required to redeem those Senior Notes.

   Duke Capital will not be required to:

   . issue, register the transfer of, or exchange any Senior Notes of a series
     during the period beginning 15 days before the date the notice is mailed
     identifying the Senior Notes of that series that have been selected for
     redemption; or

   . register the transfer of or exchange any Senior Note of that series
     selected for redemption except the unredeemed portion of a Senior Note
     being partially redeemed.

Consolidation, Merger, Conveyance or Transfer

   The Senior Indenture provides that Duke Capital may consolidate or merge
with or into, or convey or transfer all or substantially all of its properties
and assets to, another corporation or other entity. Any successor must,
however, assume Duke Capital's obligations under the Senior Indenture and the
Senior Notes issued under it, and Duke Capital must deliver to the Senior
Indenture Trustee a statement by certain of its officers and an opinion of
counsel that affirm compliance with all conditions in the Senior Indenture
relating to the transaction. When those conditions are satisfied, the successor
will succeed to and be substituted for Duke Capital under the Senior Indenture,
and Duke Capital will be relieved of its obligations under the Senior Indenture
and the Senior Notes.

Modification; Waiver

   Duke Capital may modify the Senior Indenture with the consent of the holders
of a majority in principal amount of the outstanding Senior Notes of all series
of Senior Notes that are affected by the modification, voting as one class. The
consent of the holder of each outstanding Senior Note affected is, however,
required to:

   . change the maturity date of the principal or any installment of principal
     or interest on that Senior Note;

   . reduce the principal amount, the interest rate or any premium payable upon
     redemption on that Senior Note;

   . reduce the amount of principal due and payable upon acceleration of
     maturity;

   . change the currency of payment of principal, premium or interest on that
     Senior Note;

   . impair the right to institute suit to enforce any such payment on or after
     the maturity date or redemption date;

   . reduce the percentage in principal amount of Senior Notes of any series
     required to modify the Senior Indenture, waive compliance with certain
     restrictive provisions of the Senior Indenture or waive certain defaults;
     or

   . with certain exceptions, modify the provisions of the Senior Indenture
     governing modifications of the Senior Indenture or governing waiver of
     covenants or past defaults.

In addition, Duke Capital may modify the Senior Indenture for certain other
purposes, without the consent of any holders of Senior Notes.

   The holders of a majority in principal amount of the outstanding Senior
Notes of any series may waive, for that series, Duke Capital's compliance with
certain restrictive provisions of the Senior Indenture, including the

                                      8



covenant described under "Negative Pledge." The holders of a majority in
principal amount of the outstanding Senior Notes of all series under the Senior
Indenture with respect to which a default has occurred and is continuing,
voting as one class, may waive that default for all those series, except a
default in the payment of principal or any premium or interest on any Senior
Note or a default with respect to a covenant or provision which cannot be
modified without the consent of the holder of each outstanding Senior Note of
the series affected.

Events of Default

   The following are events of default under the Senior Indenture with respect
to any series of Senior Notes, unless Duke Capital states otherwise in the
applicable prospectus supplement:

   . failure to pay principal of or any premium on any Senior Note of that
     series when due;

   . failure to pay when due any interest on any Senior Note of that series
     that continues for 60 days; for this purpose, the date on which interest
     is due is the date on which Duke Capital is required to make payment
     following any deferral of interest payments by it under the terms of
     Senior Notes that permit such deferrals;

   . failure to make any sinking fund payment when required for any Senior Note
     of that series that continues for 60 days;

   . failure to perform any covenant in the Senior Indenture (other than a
     covenant expressly included solely for the benefit of other series) that
     continues for 90 days after the Senior Indenture Trustee or the holders of
     at least 33% of the outstanding Senior Notes of that series give Duke
     Capital written notice of the default; and

   . certain bankruptcy, insolvency or reorganization events with respect to
     Duke Capital.

In the case of the fourth event of default listed above, the Senior Indenture
Trustee may extend the grace period. In addition, if holders of a particular
series have given a notice of default, then holders of at least the same
percentage of Senior Notes of that series, together with the Senior Indenture
Trustee, may also extend the grace period. The grace period will be
automatically extended if Duke Capital has initiated and is diligently pursuing
corrective action.

   Duke Capital may establish additional events of default for a particular
series and, if established, any such events of default will be described in the
applicable prospectus supplement.

   If an event of default with respect to Senior Notes of a series occurs and
is continuing, then the Senior Indenture Trustee or the holders of at least 33%
in principal amount of the outstanding Senior Notes of that series may declare
the principal amount of all Senior Notes of that series to be immediately due
and payable. However, that event of default will be considered waived at any
time after the declaration but before a judgment for payment of the money due
has been obtained if:

   . Duke Capital has paid or deposited with the Senior Indenture Trustee all
     overdue interest, the principal and any premium due otherwise than by the
     declaration and any interest on such amounts, and any interest on overdue
     interest, to the extent legally permitted, in each case with respect to
     that series, and all amounts due to the Senior Indenture Trustee; and

   . all events of default with respect to that series, other than the
     nonpayment of the principal that became due solely by virtue of the
     declaration, have been cured or waived.

   The Senior Indenture Trustee is under no obligation to exercise any of its
rights or powers at the request or direction of any holders of Senior Notes
unless those holders have offered the Senior Indenture Trustee security or
indemnity against the costs, expenses and liabilities which it might incur as a
result. The holders of a majority

                                      9



in principal amount of the outstanding Senior Notes of any series have, with
certain exceptions, the right to direct the time, method and place of
conducting any proceedings for any remedy available to the Senior Indenture
Trustee or the exercise of any power of the Senior Indenture Trustee with
respect to those Senior Notes. The Senior Indenture Trustee may withhold notice
of any default, except a default in the payment of principal or interest, from
the holders of any series if the Senior Indenture Trustee in good faith
considers it in the interest of the holders to do so.

   The holder of any Senior Note will have an absolute and unconditional right
to receive payment of the principal, any premium and, within certain
limitations, any interest on that Senior Note on its maturity date or
redemption date and to enforce those payments.

   Duke Capital is required to furnish each year to the Senior Indenture
Trustee a statement by certain of its officers to the effect that it is not in
default under the Senior Indenture or, if there has been a default, specifying
the default and its status.

Payments; Paying Agent

   The paying agent will pay the principal of any Senior Notes only if those
Senior Notes are surrendered to it. The paying agent will pay interest on
Senior Notes issued as global securities by wire transfer to the holder of
those global securities. Unless Duke Capital states otherwise in the applicable
prospectus supplement, the paying agent will pay interest on Senior Notes that
are not in global form at its office or, at Duke Capital's option:

   . by wire transfer to an account at a banking institution in the United
     States that is designated in writing to the Senior Indenture Trustee at
     least 16 days prior to the date of payment by the person entitled to that
     interest; or

   . by check mailed to the address of the person entitled to that interest as
     that address appears in the security register for those Senior Notes.

   Unless Duke Capital states otherwise in the applicable prospectus
supplement, the Senior Indenture Trustee will act as paying agent for that
series of Senior Notes, and the principal corporate trust office of the Senior
Indenture Trustee will be the office through which the paying agent acts. Duke
Capital may, however, change or add paying agents or approve a change in the
office through which a paying agent acts.

   Any money that Duke Capital has paid to a paying agent for principal or
interest on any Senior Notes which remains unclaimed at the end of two years
after that principal or interest has become due will be repaid to Duke Capital
at its request. After repayment to Duke Capital, holders should look only to
Duke Capital for those payments.

Negative Pledge

   While any of the Senior Notes remain outstanding, Duke Capital will not, and
will not permit any Principal Subsidiary (as defined below) to, create, or
permit to be created or to exist, any mortgage, lien, pledge, security interest
or other encumbrance upon any Principal Property (as defined below) of Duke
Capital or of a Principal Subsidiary or upon any shares of stock of any
Principal Subsidiary, whether such Principal Property is, or shares of stock
are, owned on or acquired after the date of the Senior Indenture, to secure any
indebtedness for borrowed money of Duke Capital, unless the Senior Notes then
outstanding are equally and ratably secured for so long as any such
indebtedness is so secured.

   The foregoing restriction does not apply with respect to, among other things:

   . purchase money mortgages, or other purchase money liens, pledges, security
     interests or encumbrances upon property that Duke Capital or any Principal
     Subsidiary acquired after the date of the Senior Indenture;

                                      10



   . mortgages, liens, pledges, security interests or other encumbrances
     existing on any property or shares of stock at the time Duke Capital or
     any Principal Subsidiary acquired it or them, including those which exist
     on any property or shares of stock of an entity with which Duke Capital or
     any Principal Subsidiary is consolidated or merged or which transfers or
     leases all or substantially all of its properties to Duke Capital or any
     Principal Subsidiary;

   . mortgages, liens, pledges, security interests or other encumbrances upon
     any property of Duke Capital or any Principal Subsidiary or shares of
     stock of any Principal Subsidiary that existed on the date of the initial
     issuance of Senior Notes or upon the property or shares of stock of any
     corporation existing at the time that corporation became a Principal
     Subsidiary;

   . pledges or deposits to secure performance in connection with bids,
     tenders, contracts (other than contracts for the payment of money) or
     leases to which Duke Capital or any Principal Subsidiary is a party;

   . liens created by or resulting from any litigation or proceeding which at
     the time is being contested in good faith by appropriate proceedings;

   . liens incurred in connection with the issuance of bankers' acceptances and
     lines of credit, bankers' liens or rights of offset and any security given
     in the ordinary course of business to banks or others to secure any
     indebtedness payable on demand or maturing within 12 months of the date
     that such indebtedness is originally incurred;

   . liens incurred in connection with repurchase, swap or other similar
     agreements (including commodity price, currency exchange and interest rate
     protection agreements);

   . liens securing industrial revenue or pollution control bonds;

   . liens, pledges, security interests or other encumbrances on any property
     arising in connection with any defeasance, covenant defeasance or
     in-substance defeasance of indebtedness of Duke Capital or any Principal
     Subsidiary;

   . liens created in connection with, and created to secure, a non-recourse
     obligation;

   . mortgages, liens, pledges, security interests or other encumbrances in
     favor of the United States of America, any state, any foreign country or
     any department, agency or instrumentality or political subdivision of any
     such jurisdiction, to secure partial, progress, advance or other payments
     pursuant to any contract or statute or to secure any indebtedness incurred
     for the purpose of financing all or any part of the purchase price or the
     cost of constructing or improving the property subject to such mortgages;

   . indebtedness which Duke Capital or any Principal Subsidiary may issue in
     connection with the consolidation or merger of Duke Capital or any
     Principal Subsidiary with or into any other entity, which may be an
     affiliate of Duke Capital or any Principal Subsidiary, in exchange for or
     otherwise in substitution for secured indebtedness of that entity ("Third
     Party Debt") which by its terms (1) is secured by a mortgage on all or a
     portion of the property of that entity, (2) prohibits that entity from
     incurring secured indebtedness, unless the Third Party Debt is secured
     equally and ratably with such secured indebtedness or (3) prohibits that
     entity from incurring secured indebtedness;

   . indebtedness of any entity which Duke Capital or any Principal Subsidiary
     is required to assume in connection with a consolidation or merger of that
     entity, with respect to which any property of Duke Capital or any
     Principal Subsidiary is subjected to a mortgage, lien, pledge, security
     interest or other encumbrance;

   . mortgages, liens, security interests or other encumbrances on property
     held or used by Duke Capital or any Principal Subsidiary in connection
     with the exploration for, or development, gathering, production, storage
     or marketing of, natural gas, oil or other minerals (including liquefied
     gas and synthetic gas);

   . mortgages, liens, pledges, security interests and other encumbrances in
     favor of Duke Capital, one or more Principal Subsidiaries, one or more
     wholly owned Subsidiaries (as defined below) of Duke Capital or any of the
     foregoing in combination;

                                      11



   . mortgages, liens, pledges, security interests or other encumbrances upon
     any property acquired, constructed, developed or improved by Duke Capital
     or any Principal Subsidiary after the date of the Senior Indenture which
     are created before, at the time of, or within 18 months after such
     acquisition--or in the case of property constructed, developed or
     improved, after the completion of the construction, development or
     improvement and commencement of full commercial operation of that
     property, whichever is later--to secure or provide for the payment of any
     part of its purchase price or cost; provided that, in the case of such
     construction, development or improvement, the mortgages, liens, pledges,
     security interests or other encumbrances shall not apply to any property
     that Duke Capital or any Principal Subsidiary owns other than real
     property that is unimproved up to that time; and

   . the replacement, extension or renewal of any mortgage, lien, pledge,
     security interest or other encumbrance described above; or the
     replacement, extension or renewal (not exceeding the principal amount of
     indebtedness so secured together with any premium, interest, fee or
     expense payable in connection with any such replacement, extension or
     renewal) of the indebtedness so secured; provided that such replacement,
     extension or renewal is limited to all or a part of the same property that
     secured the mortgage, lien, pledge, security interest or other encumbrance
     replaced, extended or renewed, plus improvements on it or additions or
     accessions to it.

In addition, Duke Capital or any Principal Subsidiary may create or assume any
other mortgage, lien, pledge, security interest or other encumbrance not
excepted in the Senior Indenture without Duke Capital equally and ratably
securing the Senior Notes, if immediately after that creation or assumption,
the principal amount of indebtedness for borrowed money of Duke Capital that
all such other mortgages, liens, pledges, security interests and other
encumbrances secure does not exceed an amount equal to 10% of Duke Capital's
common stockholder's equity as shown on its consolidated balance sheet for the
accounting period occurring immediately before the creation or assumption of
that mortgage, lien, pledge, security interest or other encumbrance.

   For purposes of the preceding paragraphs, the following terms have these
meanings: "Principal Property" means any natural gas pipeline, natural gas
gathering system, natural gas storage facility, natural gas processing plant or
other plant or facility located in the United States that in the opinion of the
Board of Directors or management of Duke Capital is of material importance to
the business conducted by Duke Capital and its consolidated subsidiaries taken
as a whole; "Principal Subsidiary" means any Subsidiary of Duke Capital that
owns a Principal Property; and "Subsidiary" means, as to any entity, a
corporation of which more than 50% of the outstanding shares of stock having
ordinary voting power (other than stock having such power only by reason of
contingency) is at the time owned, directly or indirectly, through one or more
intermediaries, or both, by such entity.

Defeasance and Covenant Defeasance

   The Senior Indenture provides that Duke Capital may be:

   . discharged from its obligations, with certain limited exceptions, with
     respect to any series of Senior Notes, as described in the Senior
     Indenture, such a discharge being called a "defeasance" in this
     prospectus; and

   . released from its obligations under certain restrictive covenants
     especially established with respect to any series of Senior Notes,
     including the covenant described under "Negative Pledge," as described in
     the Senior Indenture, such a release being called a "covenant defeasance"
     in this prospectus.

Duke Capital must satisfy certain conditions to effect a defeasance or covenant
defeasance. Those conditions include the irrevocable deposit with the Senior
Indenture Trustee, in trust, of money or government obligations which through
their scheduled payments of principal and interest would provide sufficient
money to pay the principal and any premium and interest on those Senior Notes
on the maturity dates of those payments or upon redemption.

                                      12



   Following a defeasance, payment of the Senior Notes defeased may not be
accelerated because of an event of default under the Senior Indenture.
Following a covenant defeasance, the payment of Senior Notes may not be
accelerated by reference to the covenants from which Duke Capital has been
released. A defeasance may occur after a covenant defeasance.

   Under current United States federal income tax laws, a defeasance would be
treated as an exchange of the relevant Senior Notes in which holders of those
Senior Notes might recognize gain or loss. In addition, the amount, timing and
character of amounts that holders would thereafter be required to include in
income might be different from that which would be includible in the absence of
that defeasance. Duke Capital urges investors to consult their own tax advisors
as to the specific consequences of a defeasance, including the applicability
and effect of tax laws other than United States federal income tax laws.

   Under current United States federal income tax law, unless accompanied by
other changes in the terms of the Senior Notes, a covenant defeasance should
not be treated as a taxable exchange.

Concerning the Senior Indenture Trustee

   The Chase Manhattan Bank is the Senior Indenture Trustee and the trustee
under the Subordinated Indenture. Duke Capital and certain of its affiliates
maintain deposit accounts and banking relationships with The Chase Manhattan
Bank. The Chase Manhattan Bank also serves as trustee or agent under other
indentures and agreements pursuant to which securities of Duke Capital and of
certain of its affiliates are outstanding.

   The Senior Indenture Trustee will perform only those duties that are
specifically set forth in the Senior Indenture unless an event of default under
the Senior Indenture occurs and is continuing. In case an event of default
occurs and is continuing, the Senior Indenture Trustee will exercise the same
degree of care as a prudent individual would exercise in the conduct of his or
her own affairs.

                                      13



                 DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES

   Duke Capital will issue the Junior Subordinated Notes in one or more series
under its Subordinated Indenture dated as of April 1, 1998 between Duke Capital
and The Chase Manhattan Bank, as Trustee, as supplemented from time to time.
The Subordinated Indenture is an exhibit to the registration statement, of
which this prospectus is a part.

   The Junior Subordinated Notes are unsecured obligations of Duke Capital and
are junior in right of payment to "Senior Indebtedness" of Duke Capital. You
may find a description of the subordination provisions of the Junior
Subordinated Notes, including a description of Senior Indebtedness of Duke
Capital, under "Subordination."

   Duke Capital conducts its business through subsidiaries. Accordingly, its
ability to meet its obligations under the Junior Subordinated Notes is
dependent on the earnings and cash flows of those subsidiaries and the ability
of those subsidiaries to pay dividends or to advance or repay funds to Duke
Capital. In addition, the rights that Duke Capital and its creditors would have
to participate in the assets of any such subsidiary upon the subsidiary's
liquidation or recapitalization will be subject to the prior claims of the
subsidiary's creditors. Certain subsidiaries of Duke Capital have incurred
substantial amounts of debt in the expansion of their businesses and Duke
Capital anticipates that certain of its subsidiaries will do so in the future.

   The following description of the Junior Subordinated Notes is only a summary
and is not intended to be comprehensive. For additional information you should
refer to the Subordinated Indenture.

General

   The Subordinated Indenture does not limit the amount of Subordinated Notes,
including Junior Subordinated Notes, that Duke Capital may issue under it. Duke
Capital may issue Subordinated Notes, including Junior Subordinated Notes, from
time to time under the Subordinated Indenture in one or more series by entering
into supplemental indentures or by its Board of Directors or a duly authorized
committee authorizing the issuance. Two forms of supplemental indenture to the
Subordinated Indenture (one with respect to Junior Subordinated Notes initially
issued to a Trust and the other with respect to Junior Subordinated Notes
initially issued to the public) are exhibits to the registration statement, of
which this prospectus is a part.

   The Junior Subordinated Notes of a series need not be issued at the same
time, bear interest at the same rate or mature on the same date.

   The Subordinated Indenture does not protect the holders of Junior
Subordinated Notes if Duke Capital engages in a highly leveraged transaction.

Provisions Applicable to Particular Series

   The prospectus supplement for a particular series of Junior Subordinated
Notes being offered will disclose the specific terms related to the offering,
including the price or prices at which the Junior Subordinated Notes to be
offered will be issued. Those terms may include some or all of the following:

   . the title of the series;

   . the total principal amount of the Junior Subordinated Notes of the series;

   . the date or dates on which principal is payable or the method for
     determining the date or dates, and any right that Duke Capital has to
     change the date on which principal is payable;

   . the interest rate or rates, if any, or the method for determining the rate
     or rates, and the date or dates from which interest will accrue;

                                      14



   . any interest payment dates and the regular record date for the interest
     payable on each interest payment date, if any;

   . whether Duke Capital may extend the interest payment periods and, if so,
     the terms of the extension;

   . the place or places where payments will be made;

   . whether Duke Capital has the option to redeem the Junior Subordinated
     Notes and, if so, the terms of its redemption option;

   . any obligation that Duke Capital has to redeem the Junior Subordinated
     Notes through a sinking fund or to purchase the Junior Subordinated Notes
     through a purchase fund or at the option of the holder;

   . whether the provisions described under "Defeasance and Covenant
     Defeasance" will not apply to the Junior Subordinated Notes;

   . the currency in which payments will be made if other than U.S. dollars,
     and the manner of determining the equivalent of those amounts in U.S.
     dollars;

   . if payments may be made, at Duke Capital's election or at the holder's
     election, in a currency other than that in which the Junior Subordinated
     Notes are stated to be payable, then the currency in which those payments
     may be made, the terms and conditions of the election and the manner of
     determining those amounts;

   . the portion of the principal payable upon acceleration of maturity, if
     other than the entire principal;

   . whether the Junior Subordinated Notes will be issuable as global
     securities and, if so, the securities depositary;

   . any changes in the events of default or covenants with respect to the
     Junior Subordinated Notes;

   . any index or formula used for determining principal, premium or interest;

   . if the principal payable on the maturity date will not be determinable on
     one or more dates prior to the maturity date, the amount which will be
     deemed to be such principal amount or the manner of determining it;

   . the subordination of the Junior Subordinated Notes to any other of Duke
     Capital's indebtedness, including other series of Subordinated Notes; and

   . any other terms.

   The interest rate and interest and other payment dates of each series of
Junior Subordinated Notes issued to a Trust will correspond to the rate at
which distributions will be paid and the distribution and other payment dates
of the Preferred Securities of that Trust.

   Unless Duke Capital states otherwise in the applicable prospectus
supplement, Duke Capital will issue the Junior Subordinated Notes only in fully
registered form without coupons, and there will be no service charge for any
registration of transfer or exchange of the Junior Subordinated Notes. Duke
Capital may, however, require payment to cover any tax or other governmental
charge payable in connection with any transfer or exchange. Subject to the
terms of the Subordinated Indenture and the limitations applicable to global
securities, transfers and exchanges of the Junior Subordinated Notes may be
made at The Chase Manhattan Bank, 55 Water Street, New York, New York 10041 or
at any other office maintained by Duke Capital for such purpose.

   The Junior Subordinated Notes will be issuable in denominations of $1,000
and any integral multiples of $1,000, unless Duke Capital states otherwise in
the applicable prospectus supplement.

   Duke Capital may offer and sell the Junior Subordinated Notes, including
original issue discount Junior Subordinated Notes, at a substantial discount
below their principal amount. The applicable prospectus

                                      15



supplement will describe special United States federal income tax and any other
considerations applicable to those securities. In addition, the applicable
prospectus supplement may describe certain special United States federal income
tax or other considerations, if any, applicable to any Junior Subordinated
Notes that are denominated in a currency other than U.S. dollars.

Global Securities

   Duke Capital may issue some or all of the Junior Subordinated Notes as
book-entry securities. Any such book-entry securities will be represented by
one or more fully registered global certificates. Duke Capital will register
each global security with or on behalf of a securities depositary identified in
the applicable prospectus supplement. Each global security will be deposited
with the securities depositary or its nominee or a custodian for the securities
depositary.

   As long as the securities depositary or its nominee is the registered holder
of a global security representing Junior Subordinated Notes, that person will
be considered the sole owner and holder of the global security and the Junior
Subordinated Notes it represents for all purposes. Except in limited
circumstances, owners of beneficial interests in a global security:

   . may not have the global security or any Junior Subordinated Notes it
     represents registered in their names;

   . may not receive or be entitled to receive physical delivery of
     certificated Junior Subordinated Notes in exchange for the global
     security; and

   . will not be considered the owners or holders of the global security or any
     Junior Subordinated Notes it represents for any purposes under the Junior
     Subordinated Notes or the Subordinated Indenture.

   Duke Capital will make all payments of principal and any premium and
interest on a global security to the securities depositary or its nominee as
the holder of the global security. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of securities in
definitive form. These laws may impair the ability to transfer beneficial
interests in a global security.

   Ownership of beneficial interests in a global security will be limited to
institutions having accounts with the securities depositary or its nominee,
which are called "participants" in this discussion, and to persons that hold
beneficial interests through participants. When a global security representing
Junior Subordinated Notes is issued, the securities depositary will credit on
its book-entry, registration and transfer system the principal amounts of
Junior Subordinated Notes the global security represents to the accounts of its
participants. Ownership of beneficial interests in a global security will be
shown only on, and the transfer of those ownership interests will be effected
only through, records maintained by:

   . the securities depositary, with respect to participants' interests; and

   . any participant, with respect to interests the participant holds on behalf
     of other persons.

   Payments participants make to owners of beneficial interests held through
those participants will be the responsibility of those participants. The
securities depositary may from time to time adopt various policies and
procedures governing payments, transfers, exchanges and other matters relating
to beneficial interests in a global security. None of the following will have
any responsibility or liability for any aspect of the securities depositary's
or any participant's records relating to beneficial interests in a global
security representing Junior Subordinated Notes, for payments made on account
of those beneficial interests or for maintaining, supervising or reviewing any
records relating to those beneficial interests:

   . Duke Capital;

   . the Subordinated Indenture Trustee;

   . the Trust (if the Junior Subordinated Notes are issued to a Trust); or

   . any agent of any of them.

                                      16



Redemption

   Provisions relating to the redemption of Junior Subordinated Notes will be
set forth in the applicable prospectus supplement. Unless Duke Capital states
otherwise in the applicable prospectus supplement, Duke Capital may redeem
Junior Subordinated Notes only upon notice mailed at least 30 but not more than
60 days before the date fixed for redemption.

   Duke Capital will not be required to:

   . issue, register the transfer of, or exchange any Junior Subordinated Notes
     of a series during the period beginning 15 days before the date the notice
     is mailed identifying the Junior Subordinated Notes of that series that
     have been selected for redemption; or

   . register the transfer of or exchange any Junior Subordinated Note of that
     series selected for redemption except the unredeemed portion of a Junior
     Subordinated Note being partially redeemed.

Consolidation, Merger, Conveyance or Transfer

   The Subordinated Indenture provides that Duke Capital may consolidate or
merge with or into, or convey or transfer all or substantially all of its
properties and assets to, another corporation or other entity. Any successor
must, however, assume Duke Capital's obligations under the Subordinated
Indenture and the Subordinated Notes, including the Junior Subordinated Notes,
and Duke Capital must deliver to the Subordinated Indenture Trustee a statement
by certain of its officers and an opinion of counsel that affirm compliance
with all conditions in the Subordinated Indenture relating to the transaction.
When those conditions are satisfied, the successor will succeed to and be
substituted for Duke Capital under the Subordinated Indenture, and Duke Capital
will be relieved of its obligations under the Subordinated Indenture and any
Subordinated Notes, including the Junior Subordinated Notes.

Modification; Waiver

   Duke Capital may modify the Subordinated Indenture with the consent of the
holders of a majority in principal amount of the outstanding Subordinated Notes
of all series that are affected by the modification, voting as one class. The
consent of the holder of each outstanding Subordinated Note affected is,
however, required to:

   . change the maturity date of the principal or any installment of principal
     or interest on that Subordinated Note;

   . reduce the principal amount, the interest rate or any premium payable upon
     redemption on that Subordinated Note;

   . reduce the amount of principal due and payable upon acceleration of
     maturity;

   . change the currency of payment of principal, premium or interest on that
     Subordinated Note;

   . impair the right to institute suit to enforce any such payment on or after
     the maturity date or redemption date;

   . reduce the percentage in principal amount of Subordinated Notes of any
     series required to modify the Subordinated Indenture, waive compliance
     with certain restrictive provisions of the Subordinated Indenture or waive
     certain defaults; or

   . with certain exceptions, modify the provisions of the Subordinated
     Indenture governing modifications of the Subordinated Indenture or
     governing waiver of covenants or past defaults.

In addition, Duke Capital may modify the Subordinated Indenture for certain
other purposes, without the consent of any holders of Subordinated Notes,
including Junior Subordinated Notes.

                                      17



   The holders of a majority in principal amount of the outstanding Junior
Subordinated Notes of any series may waive, for that series, Duke Capital's
compliance with certain restrictive provisions of the Subordinated Indenture.
The holders of a majority in principal amount of the outstanding Subordinated
Notes of all series under the Subordinated Indenture with respect to which a
default has occurred and is continuing, voting as one class, may waive that
default for all those series, except a default in the payment of principal or
any premium or interest on any Subordinated Note or a default with respect to a
covenant or provision which cannot be modified without the consent of the
holder of each outstanding Subordinated Note of the series affected.

   Duke Capital may not amend the Subordinated Indenture to change the
subordination of any outstanding Junior Subordinated Notes without the consent
of each holder of Senior Indebtedness that the amendment would adversely affect.

Events of Default

   The following are events of default under the Subordinated Indenture with
respect to any series of Junior Subordinated Notes, unless Duke Capital states
otherwise in the applicable prospectus supplement:

   . failure to pay principal of or any premium on any Junior Subordinated Note
     of that series when due;

   . failure to pay when due any interest on any Junior Subordinated Note of
     that series that continues for 60 days; for this purpose, the date on
     which interest is due is the date on which Duke Capital is required to
     make payment following any deferral of interest payments by it under the
     terms of Junior Subordinated Notes that permit such deferrals;

   . failure to make any sinking fund payment when required for any Junior
     Subordinated Note of that series that continues for 60 days;

   . failure to perform any covenant in the Subordinated Indenture (other than
     a covenant expressly included solely for the benefit of other series) that
     continues for 90 days after the Subordinated Indenture Trustee or the
     holders of at least 33% of the outstanding Junior Subordinated Notes of
     that series give Duke Capital written notice of the default; and

   . certain bankruptcy, insolvency or reorganization events with respect to
     Duke Capital.

In the case of the fourth event of default listed above, the Subordinated
Indenture Trustee may extend the grace period. In addition, if holders of a
particular series have given a notice of default, then holders of at least the
same percentage of Junior Subordinated Notes of that series, together with the
Subordinated Indenture Trustee, may also extend the grace period. The grace
period will be automatically extended if Duke Capital has initiated and is
diligently pursuing corrective action.

   Duke Capital may establish additional events of default for a particular
series and, if established, any such events of default will be described in the
applicable prospectus supplement.

   If an event of default with respect to Junior Subordinated Notes of a series
occurs and is continuing, then the Subordinated Indenture Trustee or the
holders of at least 33% in principal amount of the outstanding Junior
Subordinated Notes of that series may declare the principal amount of all
Junior Subordinated Notes of that series to be immediately due and payable.
However, that event of default will be considered waived at any time after the
declaration but before a judgment for payment of the money due has been
obtained if:

   . Duke Capital has paid or deposited with the Subordinated Indenture Trustee
     all overdue interest, the principal and any premium due otherwise than by
     the declaration and any interest on such amounts, and any interest on
     overdue interest, to the extent legally permitted, in each case with
     respect to that series, and all amounts due to the Subordinated Indenture
     Trustee; and

   . all events of default with respect to that series, other than the
     nonpayment of the principal that became due solely by virtue of the
     declaration, have been cured or waived.

                                      18



   In the case of Junior Subordinated Notes issued to a Trust, a holder of
Preferred Securities may institute a legal proceeding directly against Duke
Capital, without first instituting a legal proceeding against the Property
Trustee of the Trust by which those Preferred Securities were issued or any
other person or entity, for enforcement of payment to that holder of principal
or interest on an equivalent amount of Junior Subordinated Notes of the related
series on or after the due dates specified in those Junior Subordinated Notes.

   The Subordinated Indenture Trustee is under no obligation to exercise any of
its rights or powers at the request or direction of any holders of Junior
Subordinated Notes unless those holders have offered the Subordinated Indenture
Trustee security or indemnity against the costs, expenses and liabilities which
it might incur as a result. The holders of a majority in principal amount of
the outstanding Junior Subordinated Notes of any series have, with certain
exceptions, the right to direct the time, method and place of conducting any
proceedings for any remedy available to the Subordinated Indenture Trustee or
the exercise of any power of the Subordinated Indenture Trustee with respect to
those Junior Subordinated Notes. The Subordinated Indenture Trustee may
withhold notice of any default, except a default in the payment of principal or
interest, from the holders of any series if the Subordinated Indenture Trustee
in good faith considers it in the interest of the holders to do so.

   The holder of any Junior Subordinated Note will have an absolute and
unconditional right to receive payment of the principal, any premium and,
within certain limitations, any interest on that Junior Subordinated Note on
its maturity date or redemption date and to enforce those payments.

   Duke Capital is required to furnish each year to the Subordinated Indenture
Trustee a statement by certain of its officers to the effect that it is not in
default under the Subordinated Indenture or, if there has been a default,
specifying the default and its status.

Payments; Paying Agent

   The paying agent will pay the principal of any Junior Subordinated Notes
only if those Junior Subordinated Notes are surrendered to it. The paying agent
will pay interest on Junior Subordinated Notes issued as global securities by
wire transfer to the holder of those global securities. Unless Duke Capital
states otherwise in the applicable prospectus supplement, the paying agent will
pay interest on Junior Subordinated Notes that are not in global form at its
office or, at Duke Capital's option:

   . by wire transfer to an account at a banking institution in the United
     States that is designated in writing to the Subordinated Indenture Trustee
     at least 16 days prior to the date of payment by the person entitled to
     that interest; or

   . by check mailed to the address of the person entitled to that interest as
     that address appears in the security register for those Junior
     Subordinated Notes.

   Unless Duke Capital states otherwise in the applicable prospectus
supplement, the Subordinated Indenture Trustee will act as paying agent for
that series of Junior Subordinated Notes, and the principal corporate trust
office of the Subordinated Indenture Trustee will be the office through which
the paying agent acts. Duke Capital may, however, change or add paying agents
or approve a change in the office through which a paying agent acts.

   Any money that Duke Capital has paid to a paying agent for principal or
interest on any Junior Subordinated Notes which remains unclaimed at the end of
two years after that principal or interest has become due will be repaid to
Duke Capital at its request. After repayment to Duke Capital, holders should
look only to Duke Capital for those payments.

                                      19



Defeasance and Covenant Defeasance

   The Subordinated Indenture provides that Duke Capital may be:

   . discharged from its obligations, with certain limited exceptions, with
     respect to any series of Junior Subordinated Notes, as described in the
     Subordinated Indenture, such a discharge being called a "defeasance" in
     this prospectus; and

   . released from its obligations under certain restrictive covenants
     especially established with respect to a series of Junior Subordinated
     Notes, as described in the Subordinated Indenture, such a release being
     called a "covenant defeasance" in this prospectus.

   Duke Capital must satisfy certain conditions to effect a defeasance or
covenant defeasance. Those conditions include the irrevocable deposit with the
Subordinated Indenture Trustee, in trust, of money or government obligations
which through their scheduled payments of principal and interest would provide
sufficient money to pay the principal and any premium and interest on those
Junior Subordinated Notes on the maturity dates of those payments or upon
redemption. Following a defeasance, payment of the Junior Subordinated Notes
defeased may not be accelerated because of an event of default under the
Subordinated Indenture.

   Under current United States federal income tax laws, a defeasance would be
treated as an exchange of the relevant Junior Subordinated Notes in which
holders of those Junior Subordinated Notes might recognize gain or loss. In
addition, the amount, timing and character of amounts that holders would
thereafter be required to include in income might be different from that which
would be includible in the absence of that defeasance. Duke Capital urges
investors to consult their own tax advisors as to the specific consequences of
a defeasance, including the applicability and effect of tax laws other than
United States federal income tax laws.

   Junior Subordinated Notes issued to a Trust will not be subject to covenant
defeasance.

Subordination

   Each series of Junior Subordinated Notes will be subordinate and junior in
right of payment, to the extent set forth in the Subordinated Indenture, to all
Senior Indebtedness as defined below. If:

   . Duke Capital makes a payment or distribution of any of its assets to
     creditors upon its dissolution, winding-up, liquidation or reorganization,
     whether in bankruptcy, insolvency or otherwise;

   . a default beyond any grace period has occurred and is continuing with
     respect to the payment of principal, interest or any other monetary
     amounts due and payable on any Senior Indebtedness; or

   . the maturity of any Senior Indebtedness has been accelerated because of a
     default on that Senior Indebtedness,

then the holders of Senior Indebtedness generally will have the right to
receive payment, in the case of the first instance, of all amounts due or to
become due upon that Senior Indebtedness, and, in the case of the second and
third instances, of all amounts due on that Senior Indebtedness, or Duke
Capital will make provision for those payments, before the holders of any
Junior Subordinated Notes have the right to receive any payments of principal
or interest on their Junior Subordinated Notes.

   "Senior Indebtedness" means, with respect to any series of Junior
Subordinated Notes, the principal, premium, interest and any other payment in
respect of any of the following:

   . all of Duke Capital's indebtedness that is evidenced by notes, debentures,
     bonds or other securities Duke Capital sells for money or other
     obligations for money borrowed;

   . all indebtedness of others of the kinds described in the preceding
     category which Duke Capital has assumed or guaranteed or which Duke
     Capital has in effect guaranteed through an agreement to purchase,
     contingent or otherwise; and

                                      20



   . all renewals, extensions or refundings of indebtedness of the kinds
     described in either of the preceding two categories.

   Any such indebtedness, renewal, extension or refunding, however, will not be
Senior Indebtedness if the instrument creating or evidencing it or the
assumption or guarantee of it provides that it is not superior in right of
payment to or is equal in right of payment with those Junior Subordinated
Notes. Senior Indebtedness will be entitled to the benefits of the
subordination provisions in the Subordinated Indenture irrespective of the
amendment, modification or waiver of any term of the Senior Indebtedness.

   Future series of Subordinated Notes which are not Junior Subordinated Notes
may rank senior to outstanding series of Junior Subordinated Notes and would
constitute Senior Indebtedness with respect to those series.

   The Subordinated Indenture does not limit the amount of Senior Indebtedness
that Duke Capital may issue. As of March 31, 2001, Duke Capital's Senior
Indebtedness totaled approximately $3,800,000,000.

Concerning the Subordinated Indenture Trustee

   The Chase Manhattan Bank is the Subordinated Indenture Trustee and the
Senior Indenture Trustee. Duke Capital and certain of its affiliates maintain
deposit accounts and banking relationships with The Chase Manhattan Bank. The
Chase Manhattan Bank also serves as trustee or agent under other indentures and
agreements pursuant to which securities of Duke Capital and of certain of its
affiliates are outstanding.

   The Subordinated Indenture Trustee will perform only those duties that are
specifically set forth in the Subordinated Indenture unless an event of default
under the Subordinated Indenture occurs and is continuing. In case an event of
default occurs and is continuing, the Subordinated Indenture Trustee will
exercise the same degree of care as a prudent individual would exercise in the
conduct of his or her own affairs.

                                      21



                    DESCRIPTION OF THE PREFERRED SECURITIES

   Each Trust may issue only one series of Preferred Securities. The Trust
Agreement of each Trust will authorize the Administrative Trustees to issue the
Preferred Securities of that Trust on behalf of that Trust. For additional
information you should refer to the applicable Trust Agreement. The form of
Trust Agreement is an exhibit to the registration statement, of which this
prospectus is a part.

   The prospectus supplement for a particular series of Preferred Securities
being offered will disclose the specific terms related to the offering,
including the price or prices at which the Preferred Securities to be offered
will be issued. Those terms will include some or all of the following:

   . the title of the series;

   . the number of Preferred Securities of the series;

   . the yearly distribution rate, or the method of determining that rate, and
     the date or dates on which distributions will be payable;

   . the date or dates, or method of determining the date or dates, from which
     distributions will be cumulative;

   . the amount that will be paid out of the assets of the Trust to the holders
     of the Preferred Securities upon the voluntary or involuntary dissolution,
     winding-up or termination of the Trust;

   . any obligation that the Trust has to purchase or redeem the Preferred
     Securities, and the price at which, the period within which, and the terms
     and conditions upon which the Trust will purchase or redeem them;

   . any voting rights of the Preferred Securities that are in addition to
     those legally required, including any right that the holders of the
     Preferred Securities have to approve certain actions under or amendments
     to the Trust Agreement;

   . any right that the Trust has to defer distributions on the Preferred
     Securities in the event that Duke Capital extends the interest payment
     period on the related Junior Subordinated Notes; and

   . any other rights, preferences, privileges, limitations or restrictions
     upon the Preferred Securities of the series.

   Duke Capital will guarantee each series of Preferred Securities to the
extent described below under the caption "Description of the Guarantees."

   The applicable prospectus supplement will describe any material United
States federal income tax considerations that apply to the Preferred Securities.

                                      22



                         DESCRIPTION OF THE GUARANTEES

   Duke Capital will execute the Guarantees from time to time for the benefit
of the holders of the Preferred Securities of the respective Trusts. The Chase
Manhattan Bank will act as Guarantee Trustee under each Guarantee. The
Guarantee Trustee will hold each Guarantee for the benefit of the holders of
the Preferred Securities to which it relates.

   The following description of the Guarantees is only a summary and is not
intended to be comprehensive. The form of Guarantee is an exhibit to the
registration statement, of which this prospectus is a part.

General

   Duke Capital will irrevocably and unconditionally agree under each Guarantee
to pay the Guarantee Payments that are defined below, to the extent specified
in that Guarantee, to the holders of the Preferred Securities to which the
Guarantee relates, to the extent that the Guarantee Payments are not paid by or
on behalf of the related Trust. Duke Capital is required to pay the Guarantee
Payments to the extent specified in the relevant Guarantee regardless of any
defense, right of set-off or counterclaim that Duke Capital may have or may
assert against any person.

   The following payments and distributions on the Preferred Securities of a
Trust are Guarantee Payments:

   . any accrued and unpaid distributions required to be paid on the Preferred
     Securities of the Trust, but only to the extent that the Trust has funds
     legally and immediately available for those distributions;

   . the redemption price for any Preferred Securities that the Trust calls for
     redemption, including all accrued and unpaid distributions to the
     redemption date, but only to the extent that the Trust has funds legally
     and immediately available for the payment; and

   . upon a dissolution, winding-up or termination of the Trust, other than in
     connection with the distribution of Junior Subordinated Notes to the
     holders of Trust Securities of the Trust or the redemption of all the
     Preferred Securities of the Trust, the lesser of:

       . the sum of the liquidation amount and all accrued and unpaid
         distributions on the Preferred Securities of the Trust to the payment
         date, to the extent that the Trust has funds legally and immediately
         available for the payment; and

       . the amount of assets of the Trust remaining available for distribution
         to holders of the Preferred Securities of the Trust in liquidation of
         the Trust.

   Duke Capital may satisfy its obligation to make a Guarantee Payment by
making that payment directly to the holders of the related Preferred Securities
or by causing the Trust to make the payment to those holders.

   Each Guarantee will be a full and unconditional guarantee, subject to
certain subordination provisions, of the Guarantee Payments with respect to the
related Preferred Securities from the time of issuance of those Preferred
Securities, except that the Guarantee will apply only to the payment of
distributions and other payments on the Preferred Securities when the Trust has
sufficient funds legally and immediately available to make those distributions
or other payments.

   If Duke Capital does not make the required payments on the Junior
Subordinated Notes that the Property Trustee holds under a Trust, that Trust
will not make the related payments on its Preferred Securities.

                                      23



Subordination

   Duke Capital's obligations under each Guarantee will be unsecured
obligations of Duke Capital. Those obligations will rank:

   . subordinate and junior in right of payment to all of Duke Capital's other
     liabilities, other than obligations or liabilities that rank equal in
     priority or subordinate by their terms;

   . equal in priority with the most senior preferred stock that Duke Capital
     may issue and similar guarantees; and

   . senior to Duke Capital's common stock.

   Duke Capital has no preferred stock outstanding that will rank equal in
priority with the Guarantees. Duke Capital has common stock outstanding that
will rank junior to the Guarantees.

   Each Guarantee will be a guarantee of payment and not of collection. This
means that the guaranteed party may institute a legal proceeding directly
against Duke Capital, as guarantor, to enforce its rights under the Guarantee
without first instituting a legal proceeding against any other person or entity.

   The terms of the Preferred Securities will provide that each holder of the
Preferred Securities, by accepting those Preferred Securities, agrees to the
subordination provisions and other terms of the related Guarantee.

Amendments and Assignment

   Duke Capital may amend each Guarantee without the consent of any holder of
the Preferred Securities to which that Guarantee relates if the amendment does
not materially and adversely affect the rights of those holders. Duke Capital
may otherwise amend each Guarantee with the approval of the holders of at least
66 2/3% of the outstanding Preferred Securities to which that Guarantee relates.

Termination

   Each Guarantee will terminate and be of no further effect when:

   . the redemption price of the Preferred Securities to which the Guarantee
     relates is fully paid;

   . Duke Capital distributes the related Junior Subordinated Notes to the
     holders of those Preferred Securities; or

   . the amounts payable upon liquidation of the related Trust are fully paid.

   Each Guarantee will remain in effect or will be reinstated if at any time
any holder of the related Preferred Securities must restore payment of any sums
paid to that holder with respect to those Preferred Securities or under that
Guarantee.

Events of Default

   An event of default will occur under any Guarantee if Duke Capital fails to
perform any of its payment obligations under that Guarantee. The holders of a
majority of the Preferred Securities of any series may waive any such event of
default and its consequences on behalf of all of the holders of the Preferred
Securities of that series. The Guarantee Trustee is obligated to enforce the
Guarantee for the benefit of the holders of the Preferred Securities of a
series if an event of default occurs under the related Guarantee.

   The holders of a majority of the Preferred Securities to which a Guarantee
relates have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee with respect to
that Guarantee or to direct the exercise of any trust or power that the
Guarantee Trustee holds under

                                      24



that Guarantee. Any holder of the related Preferred Securities may institute a
legal proceeding directly against Duke Capital to enforce that holder's rights
under the Guarantee without first instituting a legal proceeding against the
Guarantee Trustee or any other person or entity.

Concerning the Guarantee Trustee

   The Chase Manhattan Bank is the Guarantee Trustee. It is also the Property
Trustee, the Subordinated Indenture Trustee and the Senior Indenture Trustee.
Duke Capital and certain of its affiliates maintain deposit accounts and
banking relationships with The Chase Manhattan Bank. The Chase Manhattan Bank
also serves as trustee or agent under other indentures and agreements pursuant
to which securities of Duke Capital and certain of its affiliates are
outstanding.

   The Guarantee Trustee will perform only those duties that are specifically
set forth in each Guarantee unless an event of default under the Guarantee
occurs and is continuing. In case an event of default occurs and is continuing,
the Guarantee Trustee will exercise the same degree of care as a prudent
individual would exercise in the conduct of his or her own affairs. Subject to
those provisions, the Guarantee Trustee is under no obligation to exercise any
of its powers under any Guarantee at the request of any holder of the related
Preferred Securities unless that holder offers reasonable indemnity to the
Guarantee Trustee against the costs, expenses and liabilities which it might
incur as a result.

Agreements as to Expenses and Liabilities

   Duke Capital will enter into an Agreement as to Expenses and Liabilities
under each Trust Agreement. Each Agreement as to Expenses and Liabilities will
provide that Duke Capital will, with certain exceptions, irrevocably and
unconditionally guarantee the full payment of any indebtedness, expenses or
liabilities of the related Trust to each person or entity to whom that Trust
becomes indebted or liable. The exceptions are the obligations of the Trust to
pay to the holders of the related Preferred Securities or other similar
interests in that Trust the amounts due to the holders under the terms of those
Preferred Securities or those similar interests.

                                      25



                             PLAN OF DISTRIBUTION

   The Senior Notes, the Junior Subordinated Notes and the Preferred Securities
may be sold in any of three ways:

   . through underwriters or dealers;

   . directly to a limited number of institutional purchasers or to a single
     purchaser; or

   . through agents.

   The applicable prospectus supplement will describe the terms under which the
Senior Notes, the Junior Subordinated Notes or the Preferred Securities are
offered, including:

   . the names of any underwriters, dealers or agents;

   . the purchase price and the net proceeds from the sale;

   . any underwriting discounts and other items constituting underwriters'
     compensation;

   . any initial public offering price; and

   . any discounts or concessions allowed, re-allowed or paid to dealers.

   Any underwriters or dealers may from time to time change any initial public
offering price and any discounts or concessions allowed, re-allowed or paid to
dealers.

   If underwriters participate in the sale of the Senior Notes, the Junior
Subordinated Notes or the Preferred Securities, those underwriters will acquire
the Senior Notes, Junior Subordinated Notes or Preferred Securities for their
own account and may resell them in one or more transactions, including
negotiated transactions, at a fixed public offering price or at varying prices
determined at the time of the sale.

   Unless Duke Capital states otherwise in the applicable prospectus
supplement, the obligations of any underwriter to purchase the Senior Notes,
the Junior Subordinated Notes or the Preferred Securities will be subject to
conditions, and the underwriter will be obligated to purchase all the Senior
Notes, Junior Subordinated Notes or Preferred Securities offered, except that
in some cases involving a default by an underwriter, less than all of the
Senior Notes, Junior Subordinated Notes or Preferred Securities offered may be
purchased. If the Senior Notes, the Junior Subordinated Notes or the Preferred
Securities are sold through an agent, the applicable prospectus supplement will
state the name and any commission that may be paid to the agent. Unless Duke
Capital states otherwise in the prospectus supplement, that agent will be
acting on a best-efforts basis for the period of its appointment.

   Agents and underwriters may be entitled to indemnification against certain
civil liabilities, including liabilities under the Securities Act of 1933,
under agreements entered into with the applicable Trust and Duke Capital.

   Underwriters and their affiliates may engage in transactions with, and, from
time to time, perform services for, the Trusts and Duke Capital or their
affiliates in the ordinary course of their business.

   The Senior Notes, the Junior Subordinated Notes and the Preferred Securities
may or may not be listed on a national securities exchange.
