DUKE ENERGY(R)

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

   Duke Energy Corporation is offering 30,000,000 Equity Units, Series B. The
Equity Units initially will consist of units referred to as Corporate Units
with a stated amount of $25 per Corporate Unit. Each Corporate Unit will
include a purchase contract under which you will agree to purchase from us
shares of our common stock on November 16, 2004 and we will pay to you contract
adjustment payments at the rate of 3.68% of the stated amount per year as
described in this prospectus supplement. Each Corporate Unit also initially
will include $25 principal amount of 4.32% senior notes due 2006 of our wholly
owned subsidiary, Duke Capital Corporation. Because the senior notes are
pledged as collateral for your obligation under the purchase contracts, the
Duke Capital senior notes will not trade separately from the Corporate Units
unless and until substitution is made as described in this prospectus
supplement. The Duke Capital senior notes are described in the accompanying
prospectus supplement and prospectus of Duke Capital Corporation.

   We have applied to list the Corporate Units on the New York Stock Exchange,
or NYSE, under the symbol "DUR." On November 13, 2001, the last reported sale
price of our common stock on the NYSE was $40.40 per share.

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

                         PROSPECTUS SUPPLEMENT SUMMARY

   The following is qualified in its entirety by, and should be read together
with, the more detailed information and financial statements included or
incorporated by reference in this prospectus supplement and the accompanying
prospectus. Unless otherwise indicated, all of the following information
assumes that the underwriter has not exercised its option to purchase up to an
additional 4,500,000 Corporate Units within 30 days of the date of this
prospectus supplement.

                            Duke Energy Corporation

   We are a leading integrated energy and energy services provider with the
ability to offer physical delivery and management of both electricity and
natural gas throughout the United States and abroad. We own and operate one of
the world's largest portfolios of generating plants, one of the nation's
largest natural gas pipeline systems and one of the most active energy trading
and marketing operations. We are also the largest producer of natural gas
liquids, or NGLs, in the United States. Our integrated approach to building
regional energy businesses allows us to leverage the strengths of these
businesses and allows us to earn both higher operating margins and greater
returns on our portfolio of energy assets. The services and products we provide
are offered through the following seven business segments:

   . Franchised Electric generates, transmits, distributes and sells electric
     energy in central and western North Carolina and the western portion of
     South Carolina. Its operations are conducted primarily through Duke Power
     and Nantahala Power and Light. We currently operate 17,755 net megawatts,
     or MW, of generation capacity and serve approximately two million
     customers in the Carolinas.

   . Natural Gas Transmission provides interstate transportation and storage of
     natural gas for customers primarily in the Mid-Atlantic, New England and
     southeastern states. We currently have 12,000 miles of natural gas
     pipelines and transport approximately 25% of the natural gas consumption
     of the eastern United States. These operations are conducted primarily
     through Duke Energy Gas Transmission Corporation.

   . Field Services gathers, processes, transports, markets and stores natural
     gas and produces, transports, markets and stores NGLs. Its operations are
     conducted primarily through Duke Energy Field Services, LLC, which has a
     presence in each of the major gas-producing regions of the United States.
     We currently own and operate approximately 57,000 miles of natural gas
     gathering systems and 68 natural gas processing plants in the United
     States and Canada and one high-deliverability natural gas storage facility
     in the United States.

   . North American Wholesale Energy, or NAWE, is involved in the development,
     operation and management of power generation facilities, primarily through
     Duke Energy North America, LLC and commodity sales and services related to
     natural gas and electricity, primarily through Duke Energy Trading and
     Marketing, LLC. Our current merchant generation portfolio totals
     approximately 8,000 MW, and we have under construction approximately 6,000
     MW for operation in 2002 and approximately 2,400 MW for operation in 2003.
     In addition to our facilities in operation or under construction, we have
     approximately 11,000 MW in advanced development scheduled to begin
     operation between 2003 and 2004. NAWE also includes Duke Energy Merchants,
     which develops new business lines in the evolving energy commodity markets.

   . International Energy is involved in the development, operation and
     management of natural gas and power generation facilities and energy
     trading and marketing of natural gas and electricity. Its operations are
     conducted through Duke Energy International, LLC, and its activities are
     targeted in Latin America, Asia Pacific and Europe. Our current operating
     portfolio includes approximately 5,100 MW of power generation facilities
     and approximately 1,700 miles of natural gas pipelines.

                                      S-2





   . Other Energy Services is a combination of businesses that provide
     engineering, consulting, construction and integrated energy solutions
     worldwide, primarily through Duke Engineering & Services, Inc., Duke/Fluor
     Daniel and DukeSolutions, Inc.

   . Duke Ventures is comprised of other diverse businesses. Crescent
     Resources, Inc. develops high-quality commercial, residential and
     multi-family real estate projects and manages land holdings primarily in
     the southeastern United States. DukeNet Communications, Inc. provides
     fiber optic networks for industrial, commercial and residential customers.
     Duke Capital Partners provides financing, investment banking and asset
     management services to wholesale and commercial energy markets.

Business Strategy

   Our strategy is to develop and actively manage integrated energy businesses
in targeted regions where our extensive capabilities in developing energy
assets, operating electric power, natural gas and NGLs plants, optimizing
commercial operations and managing risk can provide comprehensive energy
solutions for our customers and create value for our shareholders. The key
elements of our strategy include:

   Pursue growth opportunities in deregulating and liberalizing markets. The
growth in and restructuring of global energy markets are providing
opportunities for our business segments to capitalize on their comprehensive
capabilities. In North America, we are aggressively investing in new merchant
power facilities, expanding our natural gas pipeline infrastructure, rapidly
increasing our leading position in natural gas processing and NGLs marketing
and developing our trading, marketing and structured origination expertise
across the energy spectrum. Internationally, we are focusing on integrated
electric and natural gas opportunities in markets such as Latin America, Asia
Pacific and Europe, where deregulation, privatization and liberalization are
opening energy markets to competition.

   Develop and integrate regional energy businesses in target markets. We
currently own and operate assets and provide services ranging from natural gas
gathering to trading and marketing of energy to the distribution of electricity
to customers. Through our integrated energy network of natural gas and electric
power assets coupled with trading and marketing, we are able to maximize the
returns of our energy portfolio. This is accomplished by creating an
environment that enables the more efficient flow of information between our
trading and marketing business and our merchant businesses that own and operate
these physical assets. These enhanced returns are achieved through timely
communication of information regarding dispatch and maintenance of generation
plants, commodity positions for natural gas and electricity, forward pricing
curves and other market knowledge. Our integrated approach to building regional
energy businesses enables us to choose the best times to enter or exit a market
and effectively manage and grow our business.

   Actively manage our asset portfolio. We utilize a portfolio management
strategy, rather than focusing on stand-alone projects or assets, that strives
to capture the greatest value by seeking opportunities to invest in energy
assets in markets that have capacity needs and to divest other assets when
significant value can be realized. This strategy enables us to monetize certain
assets and redeploy the capital to higher-return assets in target markets.
Additionally, this strategy prevents the institutionalized ownership of any
asset by encouraging us to continually review our asset portfolio.

   Mitigate exposure through disciplined risk management policies. Through our
enterprise risk management group, we actively manage the risks that our
business segments face. We believe managing risk at the corporate level is
consistent with the portfolio approach we use with our assets. Our risk
management policies are designed to help determine lines of business offering
attractive risk returns, assess current and future risk/return characteristics
of the enterprise and recommend appropriate strategic modifications. We
actively manage our commodity, interest rate, foreign currency and credit risks
through established policies that limit our exposure and require daily
reporting to management of potential financial exposure. Our risk management
policies are designed to mitigate our downside exposures while complementing
the operations of each of our business segments.

Recent Developments

Acquisition of Westcoast Energy

   On September 20, 2001, we announced our proposed acquisition of Westcoast
Energy Inc., a leading North American energy company headquartered in
Vancouver, British Columbia, for approximately $3.5 billion in cash and stock.
Westcoast Energy's interests include natural gas gathering, processing,
transmission, storage and distribution, as well as power generation,
international energy businesses, and financial, information technology and
energy services businesses. As of and for the nine months ended September 30,
2001, Westcoast Energy had assets of approximately Cdn $14.7 billion and
operating revenues of approximately Cdn $9.5 billion. After the acquisition,
our natural gas-related assets will include approximately 18,900 miles of
transmission pipelines, 241 billion cubic feet of natural gas storage, 58,700
miles of gathering pipeline, 84 processing facilities, and 16,500 miles of
distribution pipelines. The transaction provides for the acquisition of all
outstanding common shares of Westcoast Energy in exchange for a combination of
cash, shares of our common stock and exchangeable shares of one of our Canadian
subsidiaries so that 50% of the consideration will be paid in cash and 50% will
be paid in stock. We intend to use the proceeds of this offering to finance a
portion of the cash consideration for the acquisition. Consummation of the
transaction is subject to regulatory approval and the approval by Westcoast
Energy shareholders. We expect that the acquisition will be completed during
the first quarter of 2002.

Duke Power Regulatory Accounting Matters

   We were notified on August 3, 2001 that the North Carolina Utilities
Commission (NCUC) and the Public Service Commission of South Carolina (PSCSC)
had undertaken a joint investigation, along with the North Carolina Public
Staff, regarding certain regulatory accounting entries for 1998 at Duke Power.
In our internal review of the fourteen entries in question, we concluded that
nine of the fourteen items were correctly classified for regulatory accounting
treatment. Four of the items were incorrectly classified for regulatory
purposes for 1998 only but did not recur thereafter. The classification of the
remaining item, distributions from mutual insurance companies, is subject to
differing interpretations for regulatory treatment. We believe that we
appropriately classified this item but we are evaluating our classification for
future years. As part of their investigation, the NCUC and PSCSC have notified
us that they will jointly engage an independent firm to conduct an audit of
Duke Power's accounting records for reporting periods from 1998 through June
30, 2001. We have fully cooperated with the NCUC and the PSCSC in their
investigation. The NCUC has requested that we place the amount of the 2001
mutual insurance distribution, approximately $33.5 million, in a deferred
credit account, pending final outcome of the independent audit.

                                 The Offering

What are the components of a Corporate Unit?

   Each Corporate Unit consists of a purchase contract and, initially, $25
principal amount of Duke Capital senior notes. The Duke Capital senior note
that is a component of each Corporate Unit is owned by you, but it will be
pledged to us to secure your obligations under the purchase contract. If the
Duke Capital senior notes are successfully remarketed or a tax event redemption
occurs, in each case as described in this prospectus supplement, the applicable
ownership interest in the Treasury portfolio will replace the Duke Capital
senior note as a component of each Corporate Unit and will be pledged to us to
secure your obligations under the purchase contract.

What is a Purchase Contract?

   Each purchase contract underlying an Equity Unit obligates the holder of the
purchase contract to purchase, and obligates us to sell, on November 16, 2004,
for $25, a fraction of a newly issued share of our common stock equal to the
"settlement rate." The settlement rate will be calculated, subject to
adjustment under the circumstances set forth in "Description of the Purchase
Contracts--Anti-dilution Adjustments," as follows:

   . if the applicable market value of our common stock is equal to or greater
     than the threshold appreciation price of $47.548, the settlement rate will
     be 0.5258;

   . if the applicable market value of our common stock is less than the
     threshold appreciation price but greater than the reference price, the
     settlement rate will be equal to the stated amount divided by the
     applicable market value; and

   . if the applicable market value is less than or equal to the reference
     price, the settlement rate will be 0.6231.

   "Applicable market value" means the average of the closing price per share
of common stock on each of the twenty consecutive trading days ending on the
third trading day immediately preceding November 16, 2004. The "reference
price" is $40.125, which is the equivalent of the last reported sale price of
our common stock on the NYSE on November 13, 2001 after giving effect to the
dividend to be paid to holders of record on November 16, 2001.

What are Treasury Units?

   Treasury Units are Equity Units consisting of a purchase contract and a
Treasury security. The Treasury security is a 2.5% undivided beneficial
interest in a zero-coupon U.S. Treasury security with a principal amount of
$1,000 that matures on November 15, 2004. The Treasury security that is a
component of each Treasury Unit will be owned by the holder of the Treasury
Unit, but it will be pledged to us to secure the holders' obligations under the
purchase contract.

How can I create Treasury Units from Corporate Units?

   Unless the Treasury portfolio has replaced the Duke Capital senior notes as
a component of Corporate Units as a result of a successful remarketing of the
Duke Capital senior notes or a tax event redemption, each holder of Corporate
Units will have the right, at any time on or prior to the fifth business day
immediately preceding November 16, 2004, to substitute for the related Duke
Capital senior notes held by the collateral agent zero-coupon Treasury
securities with the CUSIP number specified in this prospectus supplement and
that mature on November 15, 2004, in a total principal amount at maturity equal
to the aggregate principal amount of the Duke Capital senior notes for which
substitution is being made. This substitution will create Treasury Units, and
the applicable Duke Capital senior notes will be released to the holder.
Because Treasury securities are issued in multiples of $1,000, holders of
Corporate Units may make this substitution only in integral multiples of 40
Corporate Units. However, if the Treasury portfolio has replaced the Duke
Capital senior notes as a component

                                      S-5




of Corporate Units as a result of a successful remarketing of the Duke Capital
senior notes or a tax event redemption, holders of Corporate Units may make
substitutions only in multiples of 100,000 Corporate Units, at any time on or
prior to the second business day immediately preceding November 16, 2004.
Holders would also obtain the release of the appropriate applicable ownership
interest in the Treasury portfolio rather than a release of the applicable Duke
Capital senior notes.

How can I recreate Corporate Units from Treasury Units?

   Unless the Treasury portfolio has replaced the Duke Capital senior notes as
a component of Corporate Units as a result of a successful remarketing of the
Duke Capital senior notes or a tax event redemption, each holder of Treasury
Units will have the right at any time on or prior to the fifth business day
immediately preceding November 16, 2004, to substitute Duke Capital senior
notes for the related Treasury securities held by the collateral agent in an
aggregate principal amount of such Duke Capital senior notes equal to the
aggregate principal amount at stated maturity of the Treasury securities. This
substitution would recreate Corporate Units, and the applicable Treasury
securities would be released to the holder. Because Treasury securities are
issued in integral multiples of $1,000, holders of Treasury Units may make
these substitutions only in integral multiples of 40 Treasury Units. If the
Treasury portfolio has replaced the Duke Capital senior notes as a component of
Corporate Units as a result of a successful remarketing of the Duke Capital
senior notes or a tax event redemption, holders of the Treasury Units may make
this substitution at any time on or prior to the second business day
immediately preceding November 16, 2004, but using the applicable ownership
interest of the Treasury portfolio instead of Duke Capital senior notes and
only in integral multiples of 100,000 Treasury Units.

To what payments am I entitled as a holder of Corporate Units?

   Holders of Corporate Units will be entitled to receive cash distributions
consisting of quarterly distributions on the related Duke Capital senior notes
payable by Duke Capital at the rate of 4.32% of the stated amount per year and
quarterly distributions of contract adjustment payments, payable by us at the
rate of 3.68% of the stated amount per year, subject to our right to defer the
payment of such contract adjustment amounts. Each Corporate Unit has a stated
amount of $25. In addition, because the Duke Capital senior notes are subject
to the contingent payment rules, original issue discount, or OID, will accrue
on each related Duke Capital senior note.

What payments will I be entitled to if I convert my Corporate Units to Treasury
Units?

   Holders of Treasury Units will be entitled to receive quarterly cash
distributions of contract adjustment payments payable by us at the rate of
3.68% of the stated amount of $25 per year, subject to our rights of deferral
described herein. In addition, OID will accrue on each related Treasury
security.

Do we have the option to defer current payments?

   We have the right to defer the payment of contract adjustment payments until
no later than November 16, 2004. However, such deferred contract adjustment
payments would accrue additional contract adjustment payments at the rate of
8.00% per year until paid, compounded quarterly, to but excluding November 16,
2004. Duke Capital is not entitled to defer payments of interest on the Duke
Capital senior notes.

What are the payment dates for the Corporate Units?

   The current payments described above in respect of the Corporate Units will
be payable quarterly in arrears on February 16, May 16, August 16 and November
16 of each year, commencing February 16, 2002. These payments will be payable
to but excluding the earlier of November 16, 2004 or the most recent quarterly
payment date on or before any early settlement of the related purchase
contracts. These contract adjustment payments are subject to the deferral
provisions described in this prospectus supplement. Interest payments on the
Duke Capital senior notes are described below under the questions and answers
beginning with "What interest payments will I receive on the Duke Capital
senior notes?"

                                      S-6





What is remarketing?

   The Duke Capital senior notes of Corporate Unit holders first will be
remarketed on the third business day immediately preceding August 16, 2004. The
remarketing agent will use its reasonable efforts to obtain a price of
approximately 100.5% of the purchase price for the Treasury portfolio. The
portion of the proceeds from the remarketing equal to the Treasury portfolio
purchase price will be applied to purchase the Treasury portfolio. The Treasury
portfolio will be substituted for the Duke Capital senior notes and will be
pledged to the collateral agent to secure the Corporate Unit holders'
obligation to purchase our common stock under the purchase contracts. When paid
at maturity, the principal amount of the Treasury portfolio equal to the
principal amount of the Duke Capital senior notes will automatically be applied
to satisfy the Corporate Unit holders' obligations to purchase common stock
under the purchase contracts.

   If the initial remarketing of the Duke Capital senior notes on the third
business day preceding August 16, 2004 fails because the remarketing agent
cannot obtain a price of at least 100% of the Treasury portfolio purchase price
or a condition precedent to the remarketing has not been satisfied, the Duke
Capital senior notes will continue to be a component of Corporate Units, and a
second remarketing will be attempted on the third business day immediately
preceding September 16, 2004. If the second remarketing of the Duke Capital
senior notes on the third business day preceding September 16, 2004 similarly
fails, the Duke Capital senior notes will continue to be a component of
Corporate Units, and a third remarketing will be attempted on the third
business day immediately preceding October 16, 2004.

   Unless one of the first three remarketings has been successful, the Duke
Capital senior notes of Corporate Unit holders who have failed to deliver cash
on or prior to the fourth business day before November 16, 2004 in order to
satisfy their obligations under the related purchase contracts will be
remarketed for the fourth time on the third business day immediately preceding
November 16, 2004. In this final remarketing, the remarketing agent will use
its reasonable efforts to obtain a price of approximately 100.5% of the
aggregate principal amount of these Duke Capital senior notes. The portion of
the proceeds from the remarketing equal to the total principal amount of the
Duke Capital senior notes will automatically be applied to satisfy in full the
Corporate Unit holders' obligations to purchase common stock under the related
purchase contracts.

   In connection with a successful first, second or third remarketing of the
Duke Capital senior notes, the remarketing agent will deduct as a remarketing
fee an amount not exceeding 25 basis points (.25%) of the Treasury portfolio
purchase price from any amount of the proceeds in excess of the Treasury
portfolio purchase price. In connection with a successful final remarketing,
the remarketing agent will deduct as a remarketing fee an amount not exceeding
25 basis points (.25%) of the aggregate principal amount of the remarketed Duke
Capital senior notes from any amount of the proceeds in excess of the aggregate
principal amount of the remarketed Duke Capital senior notes. The remarketing
agent will remit any remaining portion of the proceeds for the benefit of the
holders.

   If the final remarketing of the Duke Capital senior notes on the third
business day prior to November 16, 2004 fails because the remarketing agent
cannot obtain a price of at least 100% of the total principal amount of the
Duke Capital senior notes or a condition precedent to the remarketing has not
been satisfied, we will exercise our rights as a secured party to dispose of
the Duke Capital senior notes in accordance with applicable law and to satisfy
in full, from the proceeds of the disposition, the holder's obligation to
purchase common stock under the related purchase contracts.

What is the Treasury portfolio?

   The Treasury portfolio is a portfolio of zero-coupon U.S. Treasury
securities consisting of

   . interest or principal strips of U.S. Treasury securities that mature on or
     prior to November 15, 2004 in an aggregate amount equal to the principal
     amount of the Duke Capital senior notes included in Corporate Units, and

                                      S-7





   . with respect to the scheduled interest payment date on the Duke Capital
     senior notes that occurs on November 16, 2004, in the case of a successful
     remarketing of the Duke Capital senior notes, or with respect to each
     scheduled interest payment date on the Duke Capital senior notes that
     occurs after the tax event redemption date and on or before November 16,
     2004, in the case of a tax event redemption, interest or principal strips
     of U.S. Treasury securities that mature on or prior to that interest
     payment date in an aggregate amount equal to the aggregate interest
     payment that would be due on that interest payment date on the principal
     amount of the Duke Capital senior notes included in Corporate Units
     assuming no reset of the interest rate on the Duke Capital senior notes.

If I am not a party to a purchase contract, may I still participate in a
remarketing of my Duke Capital senior notes?

   Holders of Duke Capital senior notes that are not components of Corporate
Units may elect, in the manner described in this prospectus supplement, to have
their Duke Capital senior notes remarketed by the remarketing agent.

Besides participating in a remarketing, how else may I satisfy my obligations
under the purchase contracts?

   Holders of Equity Units may satisfy their obligations, or their obligations
will be terminated, under the purchase contracts

   . through early settlement by the delivery of cash to the purchase contract
     agent on or prior to the fifth business day immediately preceding November
     16, 2004;

   . in the case of holders of Corporate Units only, by settling the related
     purchase contracts with cash on or prior to the fourth business day
     immediately prior to November 16, 2004 pursuant to prior notification to
     the purchase contract agent; or

   . without any further action, upon the termination of the purchase contracts
     as a result of bankruptcy, insolvency or reorganization of Duke Energy.

   If the holder of an Equity Unit settles a purchase contract early, or if the
holder's purchase contract is terminated as a result of our bankruptcy,
insolvency or reorganization, such holder will have no right to receive any
accrued contract adjustment payments or deferred contract adjustment payments.

What interest payments will I receive on the Duke Capital senior notes?

   Interest payments on the Duke Capital senior notes will be payable initially
at the annual rate of 4.32% of the principal amount of $25 per Duke Capital
senior note to, but excluding the reset effective date, which will be the third
business day following the day on which any remarketing of the Duke Capital
senior notes is successfully completed. Following a reset of the interest rate,
the Duke Capital senior notes will bear interest from the reset effective date,
at the reset rate to, but excluding, November 16, 2006. In addition, because
the Duke Capital senior notes are subject to the contingent payment rules, OID
will accrue on the Duke Capital senior notes.

What are the payment dates on the Duke Capital senior notes?

   Interest payments will be payable quarterly in arrears on each February 16,
May 16, August 16 and November 16, commencing February 16, 2002.

When will the interest rate on the Duke Capital senior notes be reset?

   The interest rate on the Duke Capital senior notes will be reset in
connection with the initial remarketing or, if it fails, the next successful
subsequent remarketing. Unless a tax event redemption has occurred, the
interest rate on the senior notes will be reset on the initial remarketing
date, which will be three business days immediately preceding August 16, 2004,
and such reset rate will become effective on August 16, 2004. However,

                                      S-8




if the initial remarketing fails, the interest rate on the senior notes will
not be reset on the initial remarketing date and instead will be reset on the
second remarketing date, which will be three business days immediately
preceding September 16, 2004, and such reset rate will become effective on
September 16, 2004. Similarly, if the second remarketing fails, the interest
rate on the Duke Capital senior notes will not be reset on the second
remarketing date and instead will be reset on the third remarketing date, which
will be three business days immediately preceding October 16, 2004, and such
interest rate will become effective on October 16, 2004. Finally, if the third
remarketing fails, the interest rate on the senior notes will not be reset on
the third remarketing date and instead will be reset on the fourth and final
remarketing date, which will be three business days immediately preceding
November 16, 2004, and such reset rate will become effective on November 16,
2004.

What is the reset rate?

   In the case of a reset on the third business day immediately preceding
August 16, 2004, September 16, 2004 or October 16, 2004, the reset rate will be
the rate determined by the reset agent as the rate the Duke Capital senior
notes should bear in order for the Duke Capital senior notes included in
Corporate Units to have an approximate aggregate market value on the reset date
of 100.5% of the Treasury portfolio purchase price. In the case of a reset on
the third business day immediately preceding November 16, 2004, the reset rate
will be the rate determined by the reset agent as the rate the Duke Capital
senior notes should bear in order for each Duke Capital senior note to have an
approximate market value of 100.5% of the aggregate principal amount of the
Duke Capital senior note. The reset rate may not exceed the maximum rate, if
any, permitted by applicable law.

When may the Duke Capital senior notes be redeemed?

   The Duke Capital senior notes are redeemable at Duke Capital's option, in
whole but not in part, upon the occurrence and continuation of a tax event
under the circumstances described in the prospectus supplement for the Duke
Capital senior notes, which accompanies this prospectus supplement. Following
any such redemption of the Duke Capital senior notes, which we refer to as a
tax event redemption, prior to November 16, 2004, investors that own Corporate
Units will own the applicable ownership percentage of the Treasury portfolio as
a component of their Corporate Units.

What are the federal income tax consequences related to the Corporate Units,
Treasury Units and Duke Capital senior notes?

   Because an Equity Unit will consist of a purchase contract and a Duke
Capital senior note, the purchase price of each Equity Unit will be allocated
between the purchase contract and the related Duke Capital senior note in
proportion to their relative fair market values at the time of purchase. Duke
Capital expects that as of the date of issuance of the Equity Units, the fair
market value of each purchase contract will be $0.0 and the fair market value
of each Duke Capital senior note will be $25.0.

   The Duke Capital senior notes will be subject to the regulations concerning
contingent payment debt instruments. As such, a holder will be subject to
federal income tax on the accrual of original issue discount in respect of the
senior notes.

   If a holder owns Treasury Units, such holder will be required to include in
gross income such holder's allocable share of any original issue discount or
acquisition discount on the Treasury Securities that accrues in such year.

   Duke Energy intends to report the purchase contract adjustment payments as
income to holders, but holders may want to consult their tax advisor concerning
alternative characterizations.

   Because there is no statutory, judicial or administrative authority directly
addressing the tax treatment of Equity Units or instruments similar to Equity
Units, each holder is urged to consult its own tax advisor concerning the tax
consequences of an investment in Equity Units.

CONSEQUENCES" IN THIS PROSPECTUS SUPPLEMENT, STARTING ON PAGE S-41.

What are the uses of proceeds from the offering?

   We expect to use the net proceeds from the offering of Corporate Units
(approximately $730.7 million, or approximately $840.3 million if the
underwriter's over-allotment option is exercised in full) to fund a portion of
the cash consideration for our proposed acquisition of Westcoast Energy Inc.

                      The Offering--Explanatory Diagrams

   The following diagrams demonstrate some of the key features of the purchase
contracts, Corporate Units, Treasury Units and the Duke Capital senior notes,
and the transformation of Corporate Units into Treasury Units and Duke Capital
senior notes.

   The following diagrams assume that the Duke Capital senior notes are
successfully remarketed and the interest rate on the Duke Capital senior notes
is reset on the third business day immediately preceding August 16, 2004.

Purchase Contract

   Corporate Units and Treasury Units both include a purchase contract under
which the investor agrees to purchase shares of our common stock at the end of
three years. In addition, these purchase contracts include unsecured contract
adjustment payments as shown in the diagrams on the following pages.

(1)For each of the percentage categories shown, the percentage of shares to be
   delivered at maturity to an investor in a Corporate Unit or Treasury Unit is
   determined by dividing (a) the related number of shares to be delivered, as
   indicated in the footnote for each category, by (b) an amount equal to $25,
   the stated amount, divided by the reference price.
(2)If the applicable market value of our common stock is less than or equal to
   $40.125, the number of shares to be delivered will be calculated by dividing
   the stated amount by the reference price. The "applicable market value"
   means the average of the closing price per share of common stock on each of
   the twenty consecutive trading days ending on the third trading day
   immediately preceding November 16, 2004.
(3)If the applicable market value of our common stock is between $40.125 and
   $47.548, the number of shares to be delivered will be calculated by dividing
   the stated amount by the applicable market value.
(4)If the applicable market value of our common stock is greater than or equal
   to $47.548, the number of shares to be delivered will be calculated by
   dividing the stated amount by the threshold appreciation price.
(5)The "reference price" is equal to $40.125.
(6)The "threshold appreciation price" is equal to $47.548.

Transforming Corporate Units into Treasury Units and Duke Capital Senior Notes

   . To create a Treasury Unit, the investor separates a Corporate Unit into
     its components--the purchase contract and the Duke Capital senior
     note--and then combines the purchase contract with a zero-coupon Treasury
     security that matures concurrently with the maturity of the purchase
     contract.

   . The investor owns the Treasury security but will pledge it to us to secure
     its obligations under the purchase contract.

   . The Treasury security together with the purchase contract constitutes a
     Treasury Unit. The Duke Capital senior note, which is no longer a
     component of the Corporate Unit, is tradeable as a separate security.

   . Following the remarketing of the Duke Capital senior notes or a tax event
     redemption, upon the transformation of a Corporate Unit into a Treasury
     Unit the applicable ownership percentage of the Treasury portfolio, rather
     than the Duke Capital senior note, will be released to the holder and will
     trade separately.

   . The investor can also transform Treasury Units and Duke Capital senior
     notes into Corporate Units. Following that transformation, the Treasury
     security, which is no longer a component of the Treasury Unit, is
     tradeable as a separate security.

   . The transformation of Corporate Units into Treasury Units and Duke Capital
     senior notes, and the transformation of Treasury Units and Duke Capital
     senior notes into Corporate Units, requires certain minimum amounts of
     securities, as more fully described in this prospectus supplement.

                                 RISK FACTORS

   Before purchasing the Equity Units, you should carefully consider the
following risk factors as well as the other information contained in this
prospectus supplement, the accompanying prospectus and the information
incorporated by reference in order to evaluate an investment in the Equity
Units.

   You assume the risk that the market value of our common stock may decline.

   Although as a holder of Equity Units you will be the beneficial owner of the
related Duke Capital senior notes, Treasury portfolio or Treasury securities,
as the case may be, you do have an obligation pursuant to the purchase contract
to buy our common stock. Prior to November 16, 2004, unless you pay cash to
satisfy your obligation under the purchase contract or the purchase contracts
are terminated due to our bankruptcy, insolvency or reorganization, either the
principal of the appropriate applicable ownership interest of the Treasury
portfolio when paid at maturity or the proceeds derived from the remarketing of
the Duke Capital senior notes, in the case of Corporate Units, or the principal
of the related Treasury securities when paid at maturity, in the case of
Treasury Units, will automatically be used to purchase a specified number of
shares of our common stock on your behalf. The market value of the common stock
received by you on November 16, 2004 may not be equal to or greater than the
effective price per share of $40.125 paid by you for our common stock on the
date of this prospectus supplement. If the applicable market value of the
common stock is less than $40.125, the aggregate market value of the common
stock issued to you pursuant to each purchase contract on November 16, 2004
will be less than the effective price per share paid by you for the common
stock on the date of this prospectus supplement. Accordingly, you assume the
risk that the market value of the common stock may decline, and that the
decline could be substantial.

   The opportunity for equity appreciation provided by an investment in the
Equity Units is less than that provided by a direct investment in our common
stock.

   Your opportunity for equity appreciation afforded by investing in the Equity
Units is less than your opportunity for equity appreciation if you directly
invested in our common stock. This opportunity is less because the market value
of the common stock to be received by you pursuant to the purchase contract on
November 16, 2004 (assuming that the market value is the same as the applicable
market value of the common stock) will only exceed the effective price per
share of $40.125 paid by you for our common stock on the date of this
prospectus supplement if the applicable market value of the common stock
exceeds the threshold appreciation price (which represents an appreciation of
approximately 18.5% over $40.125 ). This situation occurs because in this
event, you would receive on November 16, 2004 only approximately 84.4% (the
percentage equal to $40.125 divided by the threshold appreciation price) of the
shares of common stock that you would have received if you had made a direct
investment in the common stock on the date of this prospectus supplement.

   The trading prices for the Equity Units will be directly affected by the
trading prices of our common stock.

   The trading prices of Corporate Units and Treasury Units in the secondary
market will be directly affected by the trading prices of our common stock, the
general level of interest rates and our credit quality. It is impossible to
predict whether the price of the common stock or interest rates will rise or
fall. Trading prices of the common stock will be influenced by our operating
results and prospects and by economic, financial and other factors. In
addition, general market conditions, including the level of, and fluctuations
in, the trading prices of stocks generally, and sales of substantial amounts of
common stock by us in the market after the offering of the Equity Units, or the
perception that such sales could occur, could affect the price of our common
stock. Fluctuations in interest rates may give rise to arbitrage opportunities
based upon changes in the relative value of the common stock underlying the
purchase contracts and of the other components of the Equity Units. Any such
arbitrage could, in turn, affect the trading prices of the Corporate Units,
Treasury Units, Duke Capital senior notes and our common stock.


                                     S-16



   If you hold Equity Units, you will not be entitled to any rights with
respect to our common stock, but you will be subject to all changes made with
respect to our common stock.

   If you hold Equity Units, you will not be entitled to any rights with
respect to our common stock (including, without limitation, voting rights and
rights to receive any dividends or other distributions on the common stock),
but you will be subject to all changes affecting the common stock. You will
only be entitled to rights on the common stock if and when we deliver shares of
common stock in exchange for Equity Units on November 16, 2004, or as a result
of early settlement, as the case may be, and the applicable record date, if
any, for the exercise of rights occurs after that date. For example, in the
event that an amendment is proposed to our articles of incorporation or by-laws
requiring stockholder approval and the record date for determining the
stockholders of record entitled to vote on the amendment occurs prior to
delivery of the common stock, you will not be entitled to vote on the
amendment, although you will nevertheless be subject to any changes in the
powers, preferences or special rights of our common stock.

   We may issue additional shares of common stock and thereby materially and
adversely affect the price of our common stock.

   The number of shares of common stock that you are entitled to receive on
November 16, 2004 or as a result of early settlement of a purchase contract, is
subject to adjustment for certain events arising from stock splits and
combinations, stock dividends and certain other actions by us that modify our
capital structure. We will not adjust the number of shares of common stock that
you are to receive on November 16, 2004, or as a result of early settlement of
a purchase contract for other events, including offerings of common stock for
cash by us or in connection with acquisitions. We are not restricted from
issuing additional common stock during the term of the purchase contracts and
have no obligation to consider your interests for any reason. If we issue
additional shares of common stock, it may materially and adversely affect the
price of our common stock and, because of the relationship of the number of
shares to be received on November 16, 2004 to the price of the common stock,
such other events may adversely affect the trading price of Corporate Units or
Treasury Units.

   The secondary market for the Equity Units may be illiquid.

   It is not possible to predict how Corporate Units, Treasury Units or Duke
Capital senior notes will trade in the secondary market or whether the market
will be liquid or illiquid. There is currently no secondary market for either
our Corporate Units or our Treasury Units. We have applied to list the
Corporate Units on the NYSE. If the Treasury Units or the Duke Capital senior
notes are separately traded to a sufficient extent that applicable exchange
listing requirements are met, we will try to list the Duke Capital senior notes
or the Treasury Units on the same exchange as the Corporate Units. There can be
no assurance as to the liquidity of any market that may develop for the
Corporate Units, the Treasury Units or the Duke Capital senior notes, your
ability to sell these securities or whether a trading market, if it develops,
will continue. In addition, in the event you were to substitute Treasury
securities for Duke Capital senior notes or Duke Capital senior notes for
Treasury securities, thereby converting your Treasury Units to Corporate Units
or your Corporate Units to Treasury Units, as the case may be, the liquidity of
Corporate Units or Treasury Units could be adversely affected. There can be no
assurance that the Corporate Units will not be delisted from the NYSE or that
trading in the Corporate Units will not be suspended as a result of your
election to create Treasury Units by substituting collateral, which could cause
the number of Corporate Units to fall below the requirement for listing
securities on the NYSE that at least 1,000,000 Corporate Units be outstanding
at any time.

   Your rights to the pledged securities will be subject to our security
interest.

   Although you will be the beneficial owner of the related Duke Capital senior
notes, Treasury securities or Treasury portfolio, as applicable, those
securities will be pledged to Bank One Trust Company, N.A., as the collateral
agent, to secure your obligations under the related purchase contracts. Thus,
your rights to the pledged securities will be subject to our security interest.
Additionally, notwithstanding the automatic termination of the

                                     S-17



purchase contracts in the event that we become the subject of a case under the
U.S. Bankruptcy Code, the delivery of the pledged securities to you may be
delayed by the imposition of the automatic stay of Section 362 of the
Bankruptcy Code.

   Duke Capital may redeem the Duke Capital senior notes upon the occurrence of
a tax event.

   Duke Capital may redeem the Duke Capital senior notes, on not less than 30
days' nor more than 60 days' prior written notice, in whole but not in part, at
any time before November 16, 2006 if a tax event occurs and continues under the
circumstances described in this prospectus supplement. If Duke Capital
exercises this option, it will redeem the Duke Capital senior notes at the
redemption price plus accrued and unpaid interest, if any. If Duke Capital
redeems the Duke Capital senior notes, it will pay the redemption price in cash
to the holders of the Duke Capital senior notes. If the tax event redemption
occurs before August 16, 2004, or before November 16, 2004 if the Duke Capital
senior notes have not been successfully remarketed by such date, the redemption
price payable to you as a holder of Corporate Units will be distributed to the
collateral agent, who in turn will apply an amount equal to the redemption
price to purchase the Treasury portfolio on your behalf, and will remit the
remainder of the redemption price to the holder, and the Treasury portfolio
will be substituted for the Duke Capital senior notes as collateral to secure
your obligations under the purchase contracts related to the Corporate Units.
If your Duke Capital senior notes are not components of Corporate Units, you
will receive redemption payments directly. There can be no assurance as to the
impact on the market prices for the Corporate Units if the Treasury portfolio
is substituted as collateral in place of any Duke Capital senior notes so
redeemed. A tax event redemption will be a taxable event to the holders of the
Duke Capital senior notes.

   The United States federal income tax consequences of the purchase, ownership
and disposition of the Equity Units are unclear.

   No statutory, judicial or administrative authority directly addresses the
treatment of the Equity Units or instruments similar to the Equity Units for
United States federal income tax purposes. As a result, the United States
federal income tax consequences of the purchase, ownership and disposition of
Equity Units are not entirely clear. In addition, any gain on the disposition
of a Duke Capital senior note prior to the purchase contract settlement date
generally will be treated as ordinary interest income; thus, the ability to
offset such interest income with a loss, if any, on a purchase contract may be
limited. For additional tax related risks, see "Prospectus Supplement
Summary--The Offering" and "United States Federal Income Tax Consequences."

   The purchase contract agreement will not be qualified under the Trust
Indenture Act and the obligations of the purchase contract agent are limited.

   The purchase contract agreement between us and the purchase contract agent
will not be qualified as an indenture under the Trust Indenture Act of 1939,
and the purchase contract agent will not be required to qualify as a trustee
under the Trust Indenture Act. Thus, you will not have the benefit of the
protection of the Trust Indenture Act with respect to the purchase contract
agreement or the purchase contract agent. The Duke Capital senior notes
constituting a part of the Corporate Units will be issued pursuant to an
indenture, which will be qualified under the Trust Indenture Act. Accordingly,
if you hold Equity Units, you will not have the benefit of the protections of
the Trust Indenture Act other than to the extent applicable to a Duke Capital
senior note included in a Corporate Unit. The protections generally afforded
the holder of a security issued under an indenture that has been qualified
under the Trust Indenture Act include

   . disqualification of the indenture trustee for "conflicting interests," as
     defined under the Trust Indenture Act;

   . provisions preventing a trustee that is also a creditor of the issuer from
     improving its own credit position at the expense of the security holders
     immediately prior to or after a default under such indenture; and

                                     S-18



   . the requirement that the indenture trustee deliver reports at least
     annually with respect to certain matters concerning the indenture trustee
     and the securities.

   The senior notes will be classified as contingent payment debt instruments
and you will be required to accrue original issue discount.

   For United States federal income tax purposes, the senior notes will be
classified as contingent payment debt instruments. As a result, you will be
required to include original issue discount in income during your ownership of
the senior notes, subject to some adjustments. Additionally, you will generally
be required to recognize ordinary income on the gain, if any, realized on a
sale, upon maturity, or upon other disposition of the senior notes. See "United
States Federal Income Tax Consequences" beginning on page S-41.

   The trading price of the Duke Capital senior notes may not fully reflect the
value of their accrued but unpaid interest.

   The Duke Capital senior notes may trade at a price that does not fully
reflect the value of their accrued but unpaid interest. If you dispose of your
Duke Capital senior notes between record dates for interest payments, you will
be required to include in gross income the daily portions of original issue
discount through the date of disposition in income as ordinary income, and to
add this amount to your adjusted tax basis in the Duke Capital senior notes
disposed of. To the extent the selling price is less than your adjusted tax
basis, you will recognize a loss.

   Our articles of incorporation and by-law provisions, and several other
factors, could limit another party's ability to acquire us and could deprive
you of the opportunity to obtain a takeover premium for your shares of common
stock.

   A number of provisions that are in our articles of incorporation and by-laws
will make it difficult for another company to acquire us and for you to receive
any related takeover premium for the common stock underlying the Equity Units.
See "Certain Anti-Takeover Matters" and "Preference Stock Purchase Rights"
under "Description of the Common Stock" in the accompanying prospectus.

                                USE OF PROCEEDS

   The net proceeds to us from the sale of the Corporate Units in this offering
are estimated to be approximately $730.7 million (approximately $840.3 million
if the underwriter's over-allotment option is exercised in full) after
deducting the underwriting discount and estimated offering expenses. We expect
to use the net proceeds from the offering of the Corporate Units to fund a
portion of the cash consideration for our proposed acquisition of Westcoast
Energy Inc. Pending the closing of the acquisition, we intend to use the
proceeds of this offering to repay commercial paper.

common stock.

                                   DIVIDENDS

   We have paid cash dividends on our common stock without interruption since
1926. We paid a quarterly dividend of $0.275 per share in each of 1999 and 2000
and for the first three quarters of 2001, and we expect to pay a quarterly
dividend of $0.275 per share on December 17, 2001 to holders of record on
November 16, 2001. Purchasers of the Equity Units offered hereby will not be
entitled to receive that quarterly dividend or any other quarterly dividend
with a record date prior to the contract settlement date. Future dividends will
depend upon our future earnings, financial condition and other factors
affecting dividend policy.

                        DESCRIPTION OF THE EQUITY UNITS

   We will issue the Equity Units under the purchase contract agreement between
us and the purchase contract agent. The Equity Units initially will consist of
30,000,000 units referred to as Corporate Units with a stated amount per
Corporate Unit equal to $25.

   Each Corporate Unit will consist of a unit comprising:

      (1) a purchase contract under which

         . the holder will purchase from us not later than November 16, 2004,
           for the stated amount, a number of newly issued shares of our common
           stock equal to the settlement rate described below under
           "Description of the Purchase Contracts--Purchase of Common Stock,"
           and

         . we will pay the holder contract adjustment payments at the rate of
           3.68% of the stated amount per year and

      (2) either

         . a Duke Capital senior note having a principal amount equal to the
           stated amount, or

         . following a successful remarketing of the Duke Capital senior notes
           on the third business day immediately preceding either August 16,
           2004, September 16, 2004 or October 16, 2004 or the occurrence of a
           tax event redemption prior to November 16, 2004, the appropriate
           applicable ownership interest in a portfolio of zero-coupon U.S.
           Treasury securities, which we refer to as the Treasury portfolio.

   "Applicable ownership interest" means, with respect to a Corporate Unit and
the U.S. Treasury securities in the Treasury portfolio,

      (1) a 1/40, or 2.5%, undivided beneficial ownership interest in a $1,000
   principal or interest amount of a principal or interest strip in a U.S.
   Treasury security included in the Treasury portfolio that matures on or
   prior to November 15, 2004, and

      (2) for the scheduled interest payment date on the Duke Capital senior
   notes that occurs on November 16, 2004, in the case of a successful
   remarketing of the Duke Capital senior notes, or for each scheduled interest
   payment date on the Duke Capital senior notes that occurs after the tax
   event redemption date and on or before November 16, 2004, in the case of a
   tax event redemption, a 0.0274% undivided beneficial ownership interest in a
   $1,000 principal or interest amount of a principal or interest strip in a
   U.S. Treasury security included in the Treasury portfolio that matures on or
   prior to that interest payment date.

   The purchase price of each Equity Unit will be allocated between the related
purchase contract and the related Duke Capital senior note in proportion to
their respective fair market values at the time of issuance. We expect that, at
the time of issuance, the fair market value of each Duke Capital senior note
will be $25.0 and the fair market value of each purchase contract will be $0.0.
This position generally will be binding on each beneficial owner of each
Corporate Unit but not on the IRS.

   As long as an Equity Unit is in the form of a Corporate Unit, the Duke
Capital senior note or the appropriate applicable ownership interest in the
Treasury portfolio, as applicable, forming a part of the Corporate Unit will be
pledged to the collateral agent to secure the holder's obligation to purchase
common stock under the related purchase contract.

Creating Treasury Units

   Unless the Treasury portfolio has replaced the Duke Capital senior notes as
a component of the Corporate Units as the result of a successful remarketing of
the Duke Capital senior notes or a tax event redemption, each holder of
Corporate Units will have the right, at any time on or prior to the fifth
business day immediately

                                     S-23



preceding November 16, 2004, to substitute for the related Duke Capital senior
notes zero-coupon Treasury securities (CUSIP No. 912803AB9) maturing on
November 15, 2004, which we refer to as Treasury securities, in a total
principal amount at maturity equal to the aggregate principal amount of the
Duke Capital senior notes for which substitution is being made. This
substitution will create Treasury Units, and the applicable Duke Capital senior
notes will be released to the holder.

   Each Treasury Unit will consist of a unit with a stated amount of $25
comprising:

      (1) a purchase contract under which

         . the holder will purchase from us not later than November 16, 2004,
           for the stated amount, a number of newly issued shares of our common
           stock equal to the settlement rate, and

         . we will pay the holder contract adjustment payments at the rate of
           3.68% of the stated amount per year and

      (2) a 2.5% undivided beneficial ownership interest in a Treasury security
   with a principal amount of $1,000.

   Because Treasury securities are issued in multiples of $1,000, holders of
Corporate Units may make this substitution only in integral multiples of 40
Corporate Units. However, if the Treasury portfolio has replaced the Duke
Capital senior notes as a component of the Corporate Units as the result of a
successful remarketing of the Duke Capital senior notes or a tax event
redemption, holders of Corporate Units may make substitutions only in multiples
of 100,000 Corporate Units, at any time on or prior to the second business day
immediately preceding November 16, 2004. Holders would also obtain the release
of the appropriate applicable ownership interest in the Treasury portfolio
rather than a release of the applicable Duke Capital senior notes.

   To create 40 Treasury Units, the Corporate Unit holder will:

   . deposit with the collateral agent a Treasury security with the specified
     CUSIP number and maturing on November 15, 2004 that has a principal amount
     at maturity of $1,000, and

   . transfer 40 Corporate Units to the purchase contract agent accompanied by
     a notice stating that the holder has deposited a Treasury security with
     the collateral agent and requesting the release to the holder of the 40
     Duke Capital senior notes relating to the 40 Corporate Units.

   Upon the deposit and receipt of an instruction from the purchase contract
agent, the collateral agent will release the related 40 Duke Capital senior
notes from the pledge under the pledge agreement, free and clear of our
security interest, to the purchase contract agent. The purchase contract agent
then will

   . cancel the 40 Corporate Units,

   . transfer the 40 related Duke Capital senior notes to the holder, and

   . deliver 40 Treasury Units to the holder.

   The Treasury security will be substituted for the Duke Capital senior notes
and will be pledged to the collateral agent to secure the holder's obligation
to purchase common stock under the related purchase contracts. The related Duke
Capital senior notes released to the holder thereafter will trade separately
from the resulting Treasury Units.

Recreating Corporate Units

   Unless the Treasury portfolio has replaced the Duke Capital senior notes as
a component of the Corporate Units as the result of a successful remarketing of
the Duke Capital senior notes or a tax event redemption, each holder of
Treasury Units will have the right, at any time on or prior to the fifth
business day immediately

                                     S-24



preceding November 16, 2004, to substitute for the related Treasury securities
held by the collateral agent Duke Capital senior notes in an aggregate
principal amount equal to the aggregate amount payable at stated maturity of
the Treasury securities. This substitution would create Corporate Units, and
the applicable Treasury securities would be released to the holder.

   Because Treasury securities are issued in integral multiples of $1,000,
holders of Treasury Units may make this substitution only in integral multiples
of 40 Treasury Units. If the Treasury portfolio has replaced the Duke Capital
senior notes as a component of the Corporate Units as the result of a
successful remarketing of the Duke Capital senior notes or a tax event
redemption, holders of the Treasury Units may make this substitution at any
time on or prior to the second business day immediately preceding November 16,
2004, but using the appropriate applicable ownership interest in the Treasury
portfolio instead of Duke Capital senior notes and only in integral multiples
of 100,000 Treasury Units.

   To create 40 Corporate Units, the Treasury Unit holder will:

   . deposit with the collateral agent 40 Duke Capital senior notes, which Duke
     Capital senior notes must be purchased in the open market at the holder's
     expense, and

   . transfer 40 Treasury Unit certificates to the purchase contract agent
     accompanied by a notice stating that the Treasury Unit holder has
     deposited 40 Duke Capital senior notes with the collateral agent and
     requesting that the purchase contract agent instruct the collateral agent
     to release the Treasury security relating to the Treasury Units.

   Upon the deposit and receipt of an instruction from the purchase contract
agent, the collateral agent will release the related Treasury securities from
the pledge under the pledge agreement, free and clear of our security interest,
to the purchase contract agent. The purchase contract agent will then

   . cancel the 40 Treasury Units,

   . transfer the related Treasury security to the holder of Treasury Units, and

   . deliver 40 Corporate Units to the holder of Treasury Units.

   The substituted Duke Capital senior notes or the applicable ownership
interest in the Treasury portfolio will be pledged with the collateral agent to
secure the Corporate Unit holder's obligation to purchase common stock under
the related purchase contracts.

   Holders that elect to substitute pledged securities, thereby creating
Treasury Units or recreating Corporate Units, will be responsible for any fees
or expenses payable in connection with the substitution.

Current Payments

   Holders of Corporate Units are entitled to receive cash distributions
consisting of distributions on the related Duke Capital senior notes or the
Treasury portfolio, as applicable, payable at the rate of 4.32% of the stated
amount per year, and quarterly contract adjustment payments payable by us at
the rate of 3.68% of the stated amount per year, subject to our right to defer
the payment of such contract adjustment amounts. In addition, because the Duke
Capital senior notes are subject to the contingent payment rules, OID will
accrue on the related Duke Capital senior notes.

   Holders who create Treasury Units will be entitled to receive quarterly
contract adjustment payments payable by us at the rate of 3.68% of the stated
amount per year, subject to our right to defer the payment of such contract
adjustment amounts. In addition, OID will accrue on the related Treasury
securities.

   The obligations of Duke Capital with respect to the Duke Capital senior
notes will be senior and unsecured and will rank on an equal basis in right of
payment with all of its other senior unsecured obligations. Our obligations
with respect to the contract adjustment payments will be subordinate in right
of payment to our senior indebtedness. "Senior indebtedness" with respect to
the contract adjustment payments means indebtedness of any kind unless the
instrument under which such indebtedness is incurred expressly provides that it
is on a parity in right of payment with or subordinate in right of payment to
the contract adjustment payments.

                                     S-25



Voting and Certain Other Rights

   Holders of purchase contracts forming part of the Corporate Units or
Treasury Units, in their capacities as such holders, will have no voting or
other rights in respect of the common stock.

Listing of the Securities

   We have applied to list the Corporate Units on the NYSE under the symbol
"DUR." Unless and until substitution has been made as described in "--Creating
Treasury Units" or "--Recreating Corporate Units," neither the Duke Capital
senior note or Treasury portfolio component of a Corporate Unit nor the
Treasury security component of a Treasury Unit will trade separately from
Corporate Units or Treasury Units. The Duke Capital senior note or Treasury
portfolio component will trade as a unit with the purchase contract component
of the Corporate Units, and the Treasury security component will trade as a
unit with the purchase contract component of the Treasury Units. If Treasury
Units or Duke Capital senior notes are separately traded to a sufficient extent
that the applicable exchange listing requirements are met, we will endeavor to
cause the Treasury Units or Duke Capital senior notes to be listed on the
exchange on which the Corporate Units are then listed, including, if
applicable, the NYSE.

Miscellaneous

   We or our affiliates may from time to time purchase any of the securities
offered by this prospectus supplement which are then outstanding by tender, in
the open market or by private agreement.

                                     S-26



                     DESCRIPTION OF THE PURCHASE CONTRACTS

Purchase of Common Stock

   Each purchase contract underlying an Equity Unit will obligate the holder of
the purchase contract to purchase, and us to sell, on November 16, 2004, for an
amount in cash equal to the stated amount of the Equity Unit, a number of newly
issued shares of common stock equal to the "settlement rate." The settlement
rate will be calculated, subject to adjustment under the circumstances
described in "--Anti-Dilution Adjustments," as follows:

   . If the applicable market value is equal to or greater than the threshold
     appreciation price of $47.548, which is approximately 18.5% above the
     reference price of $40.125, the settlement rate will be 0.5258, which is
     equal to the stated amount divided by the threshold appreciation price.
     Accordingly, if, between the date of this prospectus supplement and the
     period during which the applicable market value is measured, the market
     price for the common stock increases to an amount that is higher than the
     threshold appreciation price, the aggregate market value of the shares of
     common stock issued upon settlement of each purchase contract will be
     higher than the stated amount, assuming that the market value is the same
     as the applicable market value of the common stock. If the market price is
     the same as the threshold appreciation price, the aggregate market value
     of the shares will be equal to the stated amount, assuming that the market
     value is the same as the applicable market value of the common stock;

   . If the applicable market value is less than the threshold appreciation
     price but greater than the reference price, the settlement rate will be
     equal to the stated amount divided by the applicable market value.
     Accordingly, if the market price for the common stock increases between
     the date of this prospectus supplement and the period during which the
     applicable market value is measured, but the market price is less than the
     threshold appreciation price, the aggregate market value of the shares of
     common stock issued upon settlement of each purchase contract will be
     equal to the stated amount, assuming that the market value is the same as
     the applicable market value of the common stock; and

   . If the applicable market value is less than or equal to the reference
     price, the settlement rate will be 0.6231, which is equal to the stated
     amount divided by the reference price. Accordingly, if the market price
     for the common stock decreases between the date of this prospectus
     supplement and the period during which the applicable market value is
     measured, the aggregate market value of the shares of common stock issued
     upon settlement of each purchase contract will be less than the stated
     amount, assuming that the market value is the same as the applicable
     market value of the common stock. If the market price stays the same, the
     aggregate market value of the shares will be equal to the stated amount,
     assuming that the market value is the same as the applicable market value
     of the common stock.

   "Applicable market value" means the average of the closing price per share
of common stock on each of the twenty consecutive trading days ending on the
third trading day immediately preceding November 16, 2004.

   "Closing price" of the common stock on any date of determination means the
closing sale price (or, if no closing price is reported, the last reported sale
price) of the common stock on the NYSE on that date or, if the common stock is
not listed for trading on the NYSE on any such date, as reported in the
composite transactions for the principal United States securities exchange on
which the common stock is so listed. If the common stock is not so listed on a
United States national or regional securities exchange, the closing price means
the last closing sale price of the common stock as reported by the Nasdaq
National Market, or, if the common stock is not so reported, the last quoted
bid price for the common stock in the over-the-counter market as reported by
the National Quotation Bureau or similar organization. If the bid price is not
available, the closing price means the market value of the common stock on the
date of determination as determined by a nationally recognized independent
investment banking firm retained by us for this purpose.

                                     S-27



   A "trading day" means a day on which the common stock

   . is not suspended from trading on any national or regional securities
     exchange or association or over-the-counter market at the close of
     business, and

   . has traded at least once on the national or regional securities exchange
     or association or over-the-counter market that is the primary market for
     the trading of the common stock.

   We will not issue any fractional shares of common stock pursuant to the
purchase contracts. In lieu of fractional shares otherwise issuable (calculated
on an aggregate basis) in respect of purchase contracts being settled by a
holder of Corporate Units or Treasury Units, the holder will be entitled to
receive an amount of cash equal to the fraction of a share times the applicable
market value.

   On the business day immediately preceding November 16, 2004, unless:

   . a holder of Corporate Units or Treasury Units has settled the related
     purchase contracts prior to November 16, 2004 through the early delivery
     of cash to the purchase contract agent in the manner described under
     "--Early Settlement,"

   . a holder of Corporate Units that include Duke Capital senior notes has
     settled the related purchase contracts with separate cash on or prior to
     the fourth business day immediately preceding November 16, 2004 pursuant
     to prior notice given in the manner described under "--Notice to Settle
     with Cash," or

   . an event described under "--Termination" has occurred,

   then

   . in the case of Corporate Units where, as a result of a successful
     remarketing of the Duke Capital senior notes or the occurrence of a tax
     event redemption, the Treasury portfolio has replaced the Duke Capital
     senior notes as a component of the Corporate Units, the proceeds, when
     paid at maturity, of the appropriate applicable ownership interest of the
     Treasury portfolio will automatically be applied to satisfy in full the
     holder's obligation to purchase common stock under the related purchase
     contracts,

   . in the case of Corporate Units where the Treasury portfolio has not
     replaced the Duke Capital senior notes as a component of the Corporate
     Units because there has not been a successful remarketing or the
     occurrence of a tax event redemption, we will exercise our rights as a
     secured party to dispose of the Duke Capital senior notes in accordance
     with applicable law, and

   . in the case of Treasury Units, the principal amount of the related
     Treasury securities, when paid at maturity, will automatically be applied
     to satisfy in full the holder's obligation to purchase common stock under
     the related purchase contracts.

   The common stock will then be issued and delivered to the holder or the
holder's designee, upon presentation and surrender of the certificate
evidencing the Equity Units and payment by the holder of any transfer or
similar taxes payable in connection with the issuance of the common stock to
any person other than the holder.

   Each holder of Corporate Units or Treasury Units, by acceptance of these
securities, will be deemed to have:

   . irrevocably agreed to be bound by the terms and provisions of the related
     purchase contracts and the pledge agreement and to have agreed to perform
     its obligations thereunder for so long as the holder remains a holder of
     the Equity Units, and

   . duly appointed the purchase contract agent as the holder's
     attorney-in-fact to enter into and perform the related purchase contracts
     and pledge agreement on behalf of and in the name of the holder.

                                     S-28



   In addition, each beneficial owner of Corporate Units or Treasury Units, by
acceptance of the interest, will be deemed to have agreed to treat

   . itself as the owner of the related Duke Capital senior notes, the
     appropriate applicable ownership interest of the Treasury portfolio or the
     Treasury securities, as the case may be, and

   . the Duke Capital senior notes as indebtedness for all United States
     federal income tax purposes.

Remarketing

   Pursuant to the remarketing agreement and subject to the terms of the
supplemental remarketing agreement among the remarketing agent, the purchase
contract agent, Duke Capital and us, unless a tax event redemption has
occurred, the Duke Capital senior notes of Corporate Unit holders first will be
remarketed on the third business day immediately preceding August 16, 2004.

   The remarketing agent will use its reasonable efforts to remarket these Duke
Capital senior notes at an aggregate price of approximately 100.5% of the
Treasury portfolio price described below. The portion of the proceeds from the
remarketing equal to the Treasury portfolio purchase price will be applied to
purchase a Treasury portfolio consisting of

   . zero-coupon interest or principal strips of U.S. Treasury securities that
     mature on or prior to November 15, 2004 in an aggregate amount equal to
     the principal amount of the Duke Capital senior notes included in
     Corporate Units, and

   . zero-coupon interest or principal strips of U.S. Treasury securities that
     mature on or prior to November 15, 2004 in an aggregate amount equal to
     the aggregate interest payment that would be due on that date on the
     principal amount of the Duke Capital senior notes included in Corporate
     Units if the interest rate on the Duke Capital senior notes were not reset
     as described in "Description of the 4.32% Senior Notes due 2006--Market
     Rate Reset" in the accompanying prospectus supplement of Duke Capital.

The Treasury portfolio will be substituted for the Duke Capital senior notes
and will be pledged to the collateral agent to secure the Corporate Unit
holders' obligation to purchase our common stock under the purchase contracts.

   As used in this context, "Treasury portfolio purchase price" means the
lowest aggregate price quoted by a primary U.S. government securities dealer in
New York City to the quotation agent on the third business day immediately
preceding August 16, 2004 for the purchase of the Treasury portfolio described
above for settlement on August 16, 2004.

   "Quotation agent" means Morgan Stanley & Co. Incorporated or its successor
or any other primary U.S. government securities dealer in New York City
selected by us.

   If (1) despite using its reasonable efforts, the remarketing agent cannot
initially remarket the related Duke Capital senior notes, other than to us, at
a price equal to or greater than 100% of the Treasury portfolio purchase price,
or (2) the initial remarketing has not occurred because a condition precedent
to the remarketing has not been fulfilled, in each case resulting in a failed
remarketing, the Duke Capital senior notes will continue to be a component of
Corporate Units, and a second remarketing will be attempted on the third
business day immediately preceding September 16, 2004. If the second
remarketing of the Duke Capital senior notes similarly fails, the Duke Capital
senior notes will continue to be a component of Corporate Units, and a third
remarketing will be attempted on the third business day immediately preceding
October 16, 2004.

   If the third remarketing of the Duke Capital senior notes on the third
business day preceding October 16, 2004 has resulted in a failed remarketing,
unless a tax event redemption has occurred, the Duke Capital senior notes of
Corporate Unit holders who either have failed to notify the purchase contract
agent on or prior to the

                                     S-29



fifth business day immediately preceding November 16, 2004 of their intention
to settle the related purchase contracts with separate cash or who have so
notified the purchase contract agent but have not delivered separate cash on or
prior to the fourth business day immediately preceding November 16, 2004, will
be remarketed on the third business day immediately preceding November 16, 2004.

   The remarketing agent will then use its reasonable efforts to remarket these
Duke Capital senior notes at a price of approximately 100.5% of their aggregate
principal amount. The portion of the proceeds from this remarketing equal to
the aggregate principal amount of the Duke Capital senior notes will be
automatically applied to satisfy in full the Corporate Unit holders'
obligations to purchase common stock.

   In connection with a successful first, second or third remarketing of the
Duke Capital senior notes, the remarketing agent will deduct as a remarketing
fee an amount not exceeding 25 basis points (.25%) of the Treasury portfolio
purchase price from any amount of the proceeds in excess of the Treasury
portfolio purchase price. In connection with a successful final remarketing,
the remarketing agent will deduct, as a remarketing fee, an amount not
exceeding 25 basis points (.25%) of the aggregate principal amount of the
remarketed Duke Capital senior notes from any amount of the proceeds in excess
of the aggregate principal amount of the remarketed Duke Capital senior notes.
The remarketing agent will then remit any remaining portion of the proceeds for
the benefit of the holders. Corporate Unit holders whose Duke Capital senior
notes are remarketed will not otherwise be responsible for the payment of any
remarketing fee in connection with the remarketing.

   If (1) despite using its reasonable efforts, the remarketing agent cannot
remarket in the final remarketing the related Duke Capital senior notes, other
than to Duke Energy, at a price equal to or greater than 100% of the aggregate
principal amount of the Duke Capital senior notes, or (2) the final remarketing
has not occurred because a condition precedent to the remarketing has not been
fulfilled, in each case resulting in a failed remarketing, we will exercise our
rights as a secured party to dispose of the Duke Capital senior notes in
accordance with applicable law and such disposition will be deemed to satisfy
in full each holder's obligation to purchase common stock under the related
purchase contracts.

   We will cause a notice of any failed remarketing to be published on the
second business day immediately preceding August 16, 2004, September 16, 2004,
October 16, 2004 or November 16, 2004, as applicable, by publication in a daily
newspaper in the English language of general circulation in the City of New
York, which is expected to be The Wall Street Journal. If required, we will
endeavor to ensure that a registration statement with regard to the full amount
of the Duke Capital senior notes to be remarketed will be effective in a form
that will enable the remarketing agent to rely on it in connection with the
remarketing process. It is currently anticipated that Morgan Stanley & Co.
Incorporated will be the remarketing agent.

Early Settlement

   A holder of Corporate Units may settle the related purchase contracts at any
time on or prior to the fifth business day immediately preceding November 16,
2004 by presenting and surrendering the related Equity Unit certificate at the
offices of the purchase contract agent with the form of "Election to Settle
Early" on the reverse side of such certificate completed and executed as
indicated, accompanied by payment to us in immediately available funds of an
amount equal to

    .  the stated amount times the number of purchase contracts being settled,
       plus

    .  if the delivery is made with respect to any purchase contract during the
       period from the close of business on any record date next preceding any
       payment date to the opening of business on such payment date, an amount
       equal to the contract adjustment payments payable on the payment date
       with respect to the purchase contract; provided that no payment is
       required if we have elected to defer the contract adjustment payments
       which would otherwise be payable on the payment date.

   If the Treasury portfolio has replaced the Duke Capital senior notes as a
component of Corporate Units as a result of a successful remarketing of the
Duke Capital senior notes or a tax event redemption, holders of the Corporate
Units may settle early only in integral multiples of 100,000 Corporate Units at
any time on or prior to the second business day immediately preceding November
16, 2004.

                                     S-30



   A holder of Treasury Units may settle the related purchase contracts at any
time on or prior to the second business day immediately preceding November 16,
2004 by presenting and surrendering the related Equity Unit certificate at the
offices of the purchase contract agent with the form of "Election to Settle
Early" on the reverse side of such certificate completed and executed as
indicated, accompanied by payment in immediately available funds of an amount
equal to

   . the stated amount times the number of purchase contracts being settled,
     plus

   . if the delivery is made with respect to any purchase contract during the
     period from the close of business on any record date next preceding any
     payment date to the opening of business on such payment date, an amount
     equal to the contract adjustment payments payable on the payment date with
     respect to the purchase contract; provided that no payment is required if
     we have elected to defer the contract adjustment payments which would
     otherwise be payable on the payment date.

   Holders of Treasury Units may settle early only in integral multiples of 40
Treasury Units.

   So long as the Equity Units are evidenced by one or more global security
certificates deposited with the depositary, procedures for early settlement
will also be governed by standing arrangements between the depositary and the
purchase contract agent.

   Upon early settlement of the purchase contracts related to any Corporate
Units or Treasury Units:

   . the holder will receive 0.5258 newly issued shares of common stock per
     Corporate Unit or Treasury Unit, subject to adjustment under the
     circumstances described under "--Anti-Dilution Adjustments," accompanied
     by this prospectus supplement, as amended or stickered,

   . the Duke Capital senior notes, the appropriate applicable ownership
     interest in the Treasury portfolio or the Treasury securities, as the case
     may be, related to the Corporate Units or Treasury Units will be
     transferred to the holder free and clear of our security interest,

   . the holder's right to receive any deferred contract adjustment payments on
     the purchase contracts being settled will be forfeited,

   . the holder's right to receive future contract adjustment payments will
     terminate, and

   . no adjustment will be made to or for the holder on account of any deferred
     contract adjustment payments or any amounts accrued in respect of contract
     adjustment payments.

   If the purchase contract agent receives an Equity Unit certificate,
accompanied by the completed "Election to Settle Early" and required
immediately available funds, from a holder of Equity Units by 5:00 p.m., New
York City time, on a business day, that day will be considered the settlement
date. If the purchase contract agent receives the above after 5:00 p.m., New
York City time, on a business day or at any time on a day that is not a
business day, the next business day will be considered the settlement date.

   Upon early settlement of purchase contracts in the manner described above,
presentation and surrender of the Equity Unit certificate evidencing the
related Corporate Units or Treasury Units and payment of any transfer or
similar taxes payable by the holder in connection with the issuance of the
related common stock to any person other than the holder of the Corporate Units
or Treasury Units, we will cause the shares of common stock being purchased to
be issued, and the related Duke Capital senior notes, the appropriate
applicable ownership interest in the Treasury portfolio or the Treasury
securities, as the case may be, securing the purchase contracts to be released
from the pledge under the pledge agreement described in "--Pledged Securities
and Pledge Agreement" and transferred, within three business days following the
settlement date, to the purchasing holder or the holder's designee.

Notice to Settle with Cash

   Unless the Treasury portfolio has replaced the Duke Capital senior notes as
a component of Corporate Units as a result of a successful remarketing of the
Duke Capital senior notes or a tax event redemption, a holder of

                                     S-31



Corporate Units may settle the related purchase contract with separate cash on
the fourth business day immediately preceding November 16, 2004. A holder of a
Corporate Unit wishing to settle the related purchase contract with separate
cash must notify the purchase contract agent by presenting and surrendering the
Corporate Unit certificate evidencing the Corporate Unit at the offices of the
purchase contract agent with the form of "Notice to Settle by Separate Cash" on
the reverse side of the certificate completed and executed as indicated on or
prior to 5:00 p.m., New York City time, on the fifth business day immediately
preceding November 16, 2004. If a holder that has given notice of its intention
to settle the related purchase contract with separate cash fails to deliver the
cash to the collateral agent on the fourth business day immediately preceding
November 16, 2004, such holder's Duke Capital senior notes will be included in
the final remarketing of Duke Capital senior notes occurring on the third
business day immediately preceding November 16, 2004. If such final remarketing
is unsuccessful, we will exercise our rights as a secured party to dispose of
the Duke Capital senior notes in accordance with applicable law and such
disposition will be deemed to satisfy in full each holder's obligation to
purchase common stock under the related purchase contracts.

Contract Adjustment Payments

   Contract adjustment payments in respect of Corporate Units and Treasury
Units will be fixed at a rate per year of 3.68% of the stated amount per
purchase contract. Contract adjustment payments payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months. Contract
adjustment payments will accrue from November 19, 2001 and will be payable
quarterly in arrears on February 16, May 16, August 16   and November 16 of
each year, commencing February 16, 2002.

   Contract adjustment payments will be payable to the holders of purchase
contracts as they appear on the books and records of the purchase contract
agent on the relevant record dates, which will be on the first day of the month
in which the relevant payment date falls. These distributions will be paid
through the purchase contract agent, who will hold amounts received in respect
of the contract adjustment payments for the benefit of the holders of the
purchase contracts relating to the Equity Units. Subject to any applicable laws
and regulations, each such payment will be made as described under
"--Book-Entry System."

   If any date on which contract adjustment payments are to be made on the
purchase contracts related to the Equity Units is not a business day, then
payment of the contract adjustment payments payable on that date will be made
on the next succeeding day which is a business day, and no interest or payment
will be paid in respect of the delay. However, if that business day is in the
next succeeding calendar year, that payment will be made on the immediately
preceding business day, in each case with the same force and effect as if made
on that payment date. A business day means any day other than a Saturday,
Sunday or any other day on which banking institutions and trust companies in
the City of New York are permitted or required by any applicable law to close.

   Our obligations with respect to contract adjustment payments will be
subordinated and junior in right of payment to our obligations under any of our
senior indebtedness.

Option to Defer Contract Adjustment Payments

   We may, at our option and upon prior written notice to the holders of the
Equity Units and the purchase contract agent, defer the payment of contract
adjustment payments on the related purchase contracts forming a part of the
Equity Units until no later than November 16, 2004. However, deferred contract
adjustment payments will bear additional contract adjustment payments at the
rate of 8.00% per year (compounding on each succeeding payment date) until
paid. If the purchase contracts are terminated (upon the occurrence of certain
events of bankruptcy, insolvency or reorganization with respect to us), the
right to receive contract adjustment payments and deferred contract adjustment
payments will also terminate.

                                     S-32



   In the event we exercise our option to defer the payment of contract
adjustment payments, then until the deferred contract adjustment payments have
been paid, we will not declare or pay dividends on, make distributions with
respect to, or redeem, purchase or acquire, or make a liquidation payment with
respect to, any of our capital stock other than

   . purchases, redemptions or acquisitions of shares of our capital stock in
     connection with any employment contract, benefit plan or other similar
     arrangement with or for the benefit of employees, officers or directors or
     a stock purchase or dividend reinvestment plan, or the satisfaction by us
     of our obligations pursuant to any contract or security outstanding on the
     date of such event,

   . as a result of a reclassification of our capital stock or the exchange or
     conversion of one class or series of our capital stock for another class
     or series of the capital stock,

   . the purchase of fractional interests in shares of our capital stock
     pursuant to the conversion or exchange provisions of the capital stock or
     the security being converted or exchanged,

   . dividends or distributions in our capital stock (or rights to acquire
     capital stock), or repurchases, redemptions or acquisitions of capital
     stock in connection with the issuance or exchange of capital stock (or
     securities convertible into or exchangeable for shares of our capital
     stock),

   . redemptions, exchanges or repurchases of any rights outstanding under a
     shareholder rights plan or the declaration or payment thereunder of a
     dividend or distribution of or with respect to rights in the future, or

   . mandatory sinking fund payments with respect to any series of our
     preferred stock or preferred stock A; provided that the aggregate stated
     value of all such series outstanding at the time of any such payment does
     not exceed 5% of the aggregate of (1) the total principal amount of all
     bonds or other securities representing secured indebtedness issued or
     assumed by us and then outstanding and (2) our capital and surplus to be
     stated on our books of account after giving effect to such payment;
     provided, however, that any moneys deposited into any sinking fund and not
     in violation of this provision may thereafter be applied to the purchase
     or redemption of such preferred stock or preferred stock A in accordance
     with the terms of such sinking fund without regard to the foregoing
     restrictions.

Anti-Dilution Adjustments

   The formula for determining the settlement rate will be subject to
adjustment, without duplication, upon the occurrence of certain events,
including:

      (a) the payment of dividends and distributions of common stock on common
   stock;

      (b) the issuance to all holders of common stock of rights, warrants or
   options (other than pursuant to any dividend reinvestment or share purchase
   plans) entitling them, for a period of up to 45 days, to subscribe for or
   purchase common stock at less than the current market price thereof;

      (c) subdivisions, splits and combinations of common stock;

      (d) distributions to all holders of common stock of evidences of our
   indebtedness, shares of capital stock, securities, cash or property
   (excluding any dividend or distribution covered by clause (a) or (b) above
   and any dividend or distribution paid exclusively in cash);

      (e) distributions (other than regular quarterly cash distributions)
   consisting exclusively of cash to all holders of common stock in an
   aggregate amount that, together with (1) other all-cash distributions (other
   than regular quarterly cash distributions) made within the preceding 12
   months and (2) any cash and the fair market value, as of the expiration of
   the tender or exchange offer referred to below, of consideration payable in
   respect of any tender or exchange offer (other than consideration payable in
   respect of any odd-lot tender offer) by us or any of our subsidiaries for
   common stock concluded within the preceding 12 months, exceeds 15% of our
   aggregate market capitalization (aggregate market capitalization being the
   product of

                                     S-33



the current market price of common stock multiplied by the number of shares of
common stock then outstanding) on the date of the distribution; and

   (f) the successful completion of a tender or exchange offer made by us or
any of our subsidiaries for common stock which involves an aggregate
consideration that, together with (1) any cash and the fair market value of
other consideration payable in respect of any tender or exchange offer (other
than consideration payable in respect of any odd-lot tender offer) by us or any
of our subsidiaries for the common stock concluded within the preceding 12
months and (2) the aggregate amount of any all-cash distributions (other than
regular quarterly cash distributions) to all holders of common stock within the
preceding 12 months, exceeds 15% of our aggregate market capitalization on the
expiration of the tender or exchange offer.

   The "current market price" per share of common stock on any day means the
average of the daily closing prices for the five consecutive trading days
selected by us commencing not more than 30 trading days before, and ending not
later than, the earlier of the day in question and the day before the "ex date"
with respect to the issuance or distribution requiring the computation. For
purposes of this paragraph, the term "ex date," when used with respect to any
issuance or distribution, will mean the first date on which the common stock
trades regular way on the applicable exchange or in the applicable market
without the right to receive the issuance or distribution.

   In the case of certain reclassifications, consolidations, mergers, sales or
transfers of assets or other transactions that cause our common stock to be
converted into the right to receive other securities, cash or property, each
purchase contract then outstanding would, without the consent of the holders of
the related Corporate Units or Treasury Units, as the case may be, become a
contract to purchase such other securities, cash and property instead of our
common stock. Upon the occurrence of any such transaction, on the stock
purchase date the settlement rate then in effect will be applied to the value,
on the stock purchase date, of the securities, cash or property a holder would
have received had it held shares covered by the purchase contract when such
transaction occurred.

   If at any time we make a distribution of property to our stockholders which
would be taxable to the stockholders as a dividend for United States federal
income tax purposes (i.e., distributions out of our current or accumulated
earnings and profits or distributions of evidences of indebtedness or assets,
but generally not stock dividends or rights to subscribe for capital stock)
and, pursuant to the settlement rate adjustment provisions of the purchase
contract agreement, the settlement rate is increased, this increase may give
rise to a taxable dividend to holders of Equity Units.

   In addition, we may make increases in the settlement rate as our board of
directors deems advisable to avoid or diminish any income tax to holders of our
capital stock resulting from any dividend or distribution of capital stock (or
rights to acquire capital stock) or from any event treated as such for income
tax purposes or for any other reasons.

   Adjustments to the settlement rate will be calculated to the nearest
1/10,000th of a share. No adjustment in the settlement rate will be required
unless the adjustment would require an increase or decrease of at least one
percent in the settlement rate. However, any adjustments which are not required
to be made because they would have required an increase or decrease of less
than one percent will be carried forward and taken into account in any
subsequent adjustment.

   We will be required, within ten business days following the adjustment to
the settlement rate, to provide written notice to the purchase contract agent
of the occurrence of the adjustment and a statement in reasonable detail
setting forth the method by which the adjustment to the settlement rate was
determined and setting forth the revised settlement rate.

   Each adjustment to the settlement rate will result in a corresponding
adjustment to the number of shares of common stock issuable upon early
settlement of a purchase contract.

                                     S-34



Termination

   The purchase contracts, and our rights and obligations and the rights and
obligations of the holders of the Equity Units under the purchase contracts,
including the right and obligation to purchase common stock and the right to
receive accrued contract adjustment payments or deferred contract adjustment
payments, will immediately and automatically terminate upon the occurrence of
certain events of bankruptcy, insolvency or reorganization with respect to Duke
Energy. Upon any termination, the collateral agent will release the related
Duke Capital senior notes, the appropriate applicable ownership interest of the
Treasury portfolio or the Treasury securities, as the case may be, held by it
to the purchase contract agent for distribution to the holders, subject, in the
case of the Treasury portfolio or the Treasury securities, to the purchase
contract agent's disposition of the subject securities for cash, and the
payment of this cash to the holders, to the extent that the holders would
otherwise have been entitled to receive less than $1,000 principal amount or
interest, as the case may be, at maturity of any such security. Upon any
termination, however, the release and distribution may be subject to a delay.
In the event that we become the subject of a case under the U.S. Bankruptcy
Code, the delay may occur as a result of the automatic stay under the
Bankruptcy Code and continue until the automatic stay has been lifted. We
expect any such delay to be limited.

Pledged Securities and Pledge Agreement

   Pledged securities will be pledged to the collateral agent, for our benefit,
pursuant to the pledge agreement to secure the obligations of holders of Equity
Units to purchase common stock under the related purchase contracts. The rights
of holders of Equity Units to the related pledged securities will be subject to
our security interest created by the pledge agreement.

   No holder of Corporate Units or Treasury Units will be permitted to withdraw
the pledged securities related to the Corporate Units or Treasury Units from
the pledge arrangement except

   . to substitute Treasury securities for the related Duke Capital senior
     notes or the appropriate applicable ownership interest of the Treasury
     portfolio, as the case may be, as provided for under "Description of the
     Equity Units--Creating Treasury Units,"

   . to substitute Duke Capital senior notes or the appropriate applicable
     ownership interest of the Treasury portfolio, as the case may be, for the
     related Treasury securities, as provided for under "Description of the
     Equity Units--Recreating Corporate Units," or

   . upon the termination or early settlement of the related purchase contracts.

   Subject to the security interest and the terms of the purchase contract
agreement and the pledge agreement, each holder of Corporate Units, unless the
Treasury portfolio has replaced the Duke Capital senior notes as a component of
Corporate Units as a result of a successful remarketing of the Duke Capital
senior notes or a tax event redemption, will be entitled through the purchase
contract agent and the collateral agent to all of the proportional rights of
the related Duke Capital senior notes, including voting and redemption rights.
Each holder of Treasury Units and each holder of Corporate Units, if the
Treasury portfolio has replaced the Duke Capital senior notes as a component of
Corporate Units as a result of a successful remarketing of the Duke Capital
senior notes or a tax event redemption, will retain beneficial ownership of the
related Treasury securities or the appropriate applicable ownership interest of
the Treasury portfolio, as applicable, pledged in respect of the related
purchase contracts. We will have no interest in the pledged securities other
than our security interest.

   Except as described in "Certain Provisions of the Purchase Contract
Agreement and the Pledge Agreement--General," the collateral agent will, upon
receipt, if any, of payments on the pledged securities, distribute the payments
to the purchase contract agent, which will in turn distribute those payments,
together with contract adjustment payments received from us, to the persons in
whose names the related Corporate Units or Treasury Units are registered at the
close of business on the record date immediately preceding the date of payment.

                                     S-35



Book-Entry System

   The Depository Trust Company, which we refer to along with its successors in
this capacity as the depositary, will act as securities depositary for the
Equity Units. The Equity Units will be issued only as fully registered
securities registered in the name of Cede & Co., the depositary's nominee. One
or more fully registered global security certificates, representing the total
aggregate number of Equity Units, will be issued and will be deposited with the
depositary and will bear a legend regarding the restrictions on exchanges and
registration of transfer referred to below.

   The laws of some jurisdictions may require that some purchasers of
securities take physical delivery of securities in definitive form. These laws
may impair the ability to transfer beneficial interests in the Equity Units so
long as the Equity Units are represented by global security certificates.

   The depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934. The depositary holds securities that its participants
deposit with the depositary. The depositary also facilitates the settlement
among participants of securities transactions, including transfers and pledges,
in deposited securities through electronic computerized book-entry changes in
participants' accounts, thereby eliminating the need for physical movement of
securities certificates. Direct participants include securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. The depositary is owned by a number of its direct participants
and by the NYSE, the American Stock Exchange, Inc., and the National
Association of Securities Dealers, Inc. Access to the depositary's system is
also available to others, including securities brokers and dealers, banks and
trust companies that clear transactions through or maintain a direct or
indirect custodial relationship with a direct participant either directly or
indirectly. The rules applicable to the depositary and its participants are on
file with the SEC.

   Although the depositary has agreed to the foregoing procedures in order to
facilitate transfer of interests in the global security certificates among
participants, the depositary is under no obligation to perform or continue to
perform these procedures, and these procedures may be discontinued at any time.
We will not have any responsibility for the performance by the depositary or
its direct participants or indirect participants under the rules and procedures
governing the depositary.

   In the event that

   . the depositary notifies us that it is unwilling or unable to continue as a
     depositary for the global security certificates and no successor
     depositary has been appointed within 90 days after this notice,

   . the depositary at any time ceases to be a clearing agency registered under
     the Securities Exchange Act when the depositary is required to be so
     registered to act as the depositary and no successor depositary has been
     appointed within 90 days after we learn that the depositary has ceased to
     be so registered, or

   . we, in our sole discretion, determine that the global security
     certificates shall be so exchangeable,

certificates for the Equity Units will be printed and delivered in exchange for
beneficial interests in the global security certificates. Any global Equity
Unit that is exchangeable pursuant to the preceding sentence will be
exchangeable for Equity Unit certificates registered in the names directed by
the depositary. We expect that these instructions will be based upon directions
received by the depositary from its participants with respect to ownership of
beneficial interests in the global security certificates.

   As long as the depositary or its nominee is the registered owner of the
global security certificates, the depositary or its nominee, as the case may
be, will be considered the sole owner and holder of the global security

                                     S-36



certificates and all Equity Units represented by these certificates for all
purposes under the Equity Units and the purchase contract agreement. Except in
the limited circumstances referred to above, owners of beneficial interests in
global security certificates

   . will not be entitled to have such global security certificates or the
     Equity Units represented by these certificates registered in their names,

   . will not receive or be entitled to receive physical delivery of Equity
     Unit certificates in exchange for beneficial interests in global security
     certificates, and

   . will not be considered to be owners or holders of the global security
     certificates or any Equity Units represented by these certificates for any
     purpose under the Equity Units or the purchase contract agreement.

   All payments on the Equity Units represented by the global security
certificates and all transfers and deliveries of related Duke Capital senior
notes, Treasury portfolio, Treasury securities and common stock will be made to
the depositary or its nominee, as the case may be, as the holder of the
securities.

   Ownership of beneficial interests in the global security certificates will
be limited to participants or persons that may hold beneficial interests
through institutions that have accounts with the depositary or its nominee.
Ownership of beneficial interests in global security certificates will be shown
only on, and the transfer of those ownership interests will be effected only
through, records maintained by the depositary or its nominee, with respect to
participants' interests, or any participant, with respect to interests of
persons held by the participant on their behalf. Procedures for settlement of
purchase contracts on November 16, 2004 or upon early settlement will be
governed by arrangements among the depositary, participants and persons that
may hold beneficial interests through participants designed to permit
settlement without the physical movement of certificates. Payments, transfers,
deliveries, exchanges and other matters relating to beneficial interests in
global security certificates may be subject to various policies and procedures
adopted by the depositary from time to time. None of Duke Energy, Duke Capital,
the purchase contract agent or any agent of Duke Energy, Duke Capital or the
purchase contract agent will have any responsibility or liability for any
aspect of the depositary's or any participant's records relating to, or for
payments made on account of, beneficial interests in global security
certificates, or for maintaining, supervising or reviewing any of the
depositary's records or any participant's records relating to these beneficial
ownership interests.

   The information in this section concerning the depositary and its book-entry
system has been obtained from sources that we believe to be reliable, but we
have not attempted to verify the accuracy this information.

                                     S-37



                  CERTAIN PROVISIONS OF THE PURCHASE CONTRACT
                      AGREEMENT AND THE PLEDGE AGREEMENT

General

   Distributions on the Equity Units will be payable, purchase contracts (and
documents relating to the Equity Units and purchase contracts) will be settled,
and transfers of the Equity Units will be registrable at the office of the
purchase contract agent in the Borough of Manhattan, The City of New York. In
addition, if the Equity Units do not remain in book-entry form, payment of
distributions on the Equity Units may be made, at our option, by check mailed
to the address of the person entitled to payment as shown on the security
register or by a wire transfer to the account designated by such person by a
prior written notice.

   Shares of common stock will be delivered on November 16, 2004 (or earlier
upon early settlement), or, if the purchase contracts have terminated, the
related pledged securities will be delivered potentially after a delay as a
result of the imposition of the automatic stay under the Bankruptcy Code (see
"Description of the Purchase Contracts--Termination"), in each case upon
presentation and surrender of the Equity Unit certificate at the office of the
purchase contract agent.

   If a holder of outstanding Corporate Units or Treasury Units fails to
present and surrender the Equity Unit certificate evidencing the Corporate
Units or Treasury Units to the purchase contract agent on November 16, 2004,
the shares of common stock issuable in settlement of the related purchase
contract will be registered in the name of the purchase contract agent. The
shares, together with any distributions, will be held by the purchase contract
agent as agent for the benefit of the holder until the Equity Unit certificate
is presented and surrendered or the holder provides satisfactory evidence that
the certificate has been destroyed, lost or stolen, together with any indemnity
that may be required by the purchase contract agent and us.

   If the purchase contracts have terminated prior to November 16, 2004, the
related pledged securities have been transferred to the purchase contract agent
for distribution to the holders, and a holder fails to present and surrender
the Equity Unit certificate evidencing the holder's Corporate Units or Treasury
Units to the purchase contract agent, the related pledged securities delivered
to the purchase contract agent and payments on the pledged securities will be
held by the purchase contract agent as agent for the benefit of the holder
until the Equity Unit certificate is presented or the holder provides the
evidence and indemnity described above.

   The purchase contract agent will have no obligation to invest or to pay
interest on any amounts held by the purchase contract agent pending
distribution, as described above.

   No service charge will be made for any registration of transfer or exchange
of the Equity Units, except for any tax or other governmental charge that may
be imposed in connection with a transfer or exchange.

Modification

   With certain exceptions contained in the purchase contract agreement and the
pledge agreement for modifications that are not adverse to holders, the
purchase contract agreement and the pledge agreement will contain provisions
permitting us and the purchase contract agent or collateral agent, as the case
may be, with the consent of the holders of not less than a majority of the
purchase contracts at the time outstanding, to modify the terms of the purchase
contracts, the purchase contract agreement and the pledge agreement. However,
no such modification may, without the consent of the holder of each outstanding
purchase contract affected by the modification,

   . change any payment date,

   . change the amount or type of pledged securities related to the purchase
     contract, impair the right of the holder of any pledged securities to
     receive distributions on the pledged securities or otherwise adversely
     affect the holder's rights in or to the pledged securities,

                                     S-38



   . change the place or currency of payment or reduce any contract adjustment
     payments or deferred contract adjustment payments,

   . impair the right to institute suit for the enforcement of the purchase
     contract, any contract adjustment payments or any deferred contract
     adjustment payments,

   . reduce the number of shares of common stock purchasable under the purchase
     contract, increase the price to purchase common stock upon settlement of
     the purchase contract, change the purchase contract settlement date or the
     right to early settlement or otherwise adversely affect the holder's
     rights under the purchase contract or

   . reduce the above-stated percentage of outstanding purchase contracts the
     consent of the holders of which is required for the modification or
     amendment of the provisions of the purchase contracts, the purchase
     contract agreement or the pledge agreement.

If any amendment or proposal referred to above would adversely affect only the
Corporate Units or the Treasury Units, then only the affected class of holders
will be entitled to vote on the amendment or proposal, and the amendment or
proposal will not be effective except with the consent of the holders of not
less than a majority of the affected class or of all of the holders of the
affected classes, as applicable.

No Consent to Assumption

   Each holder of Corporate Units or Treasury Units, by acceptance of these
securities, will under the terms of the purchase contract agreement and the
Corporate Units or Treasury Units, as applicable, be deemed expressly to have
withheld any consent to the assumption (i.e., affirmance) of the related
purchase contracts by us or our trustee if we become the subject of a case
under the Bankruptcy Code.

Consolidation, Merger, Sale or Conveyance

   We will covenant in the purchase contract agreement that we will not merge
with and into, consolidate with or convert into any other entity or sell,
assign, transfer, lease or convey all or substantially all of our properties
and assets to any person or entity, unless (1) the successor entity is an
entity organized and existing under the laws of the United States of America or
a U.S. state or the District of Columbia and that entity expressly assumes our
obligations under the purchase contracts, the purchase contract agreement, the
pledge agreement and the remarketing agreement and (2) the successor entity is
not, immediately after the merger, consolidation, conversion, sale, assignment,
transfer, lease or conveyance, in default of its payment obligations under the
purchase contracts, the purchase contract agreement, the pledge agreement and
the remarketing agreement or in material default in the performance of any
other covenants under these agreements.

Title

   We, the purchase contract agent and the collateral agent may treat the
registered owner of any Equity Units as the absolute owner of the Equity Units
for the purpose of making payment and settling the related purchase contracts
and for all other purposes.

Replacement of Equity Unit Certificates

   In the event that physical certificates have been issued, any mutilated
Equity Unit certificate will be replaced by us at the expense of the holder
upon surrender of the certificate to the purchase contract agent. Equity Unit
certificates that become destroyed, lost or stolen will be replaced by us at
the expense of the holder upon delivery to us and the purchase contract agent
of evidence of their destruction, loss or theft satisfactory to us and the
purchase contract agent. In the case of a destroyed, lost or stolen Equity Unit
certificate, an indemnity satisfactory to the purchase contract agent and us
may be required at the expense of the holder of the Equity Units evidenced by
the certificate before a replacement will be issued.

                                     S-39



   Notwithstanding the foregoing, we will not be obligated to issue any
Corporate Unit or Treasury Unit certificates on or after the business day
immediately preceding November 16, 2004 (or after early settlement) or after
the purchase contracts have terminated. The purchase contract agreement will
provide that, in lieu of the delivery of a replacement Equity Unit certificate
following November 16, 2004, the purchase contract agent, upon delivery of the
evidence and indemnity described above, will deliver the common stock issuable
pursuant to the purchase contracts included in the Corporate Units or Treasury
Units evidenced by the certificate, or, if the purchase contracts have
terminated prior to November 16, 2004, transfer the pledged securities included
in the Corporate Units or Treasury Units evidenced by the certificate.

Governing Law

   The purchase contract agreement, the pledge agreement and the purchase
contracts will be governed by, and construed in accordance with, the laws of
the State of New York.

Information Concerning the Purchase Contract Agent

   JPMorgan Chase Bank will be the purchase contract agent. The purchase
contract agent will act as the agent for the holders of Corporate Units and
Treasury Units from time to time. The purchase contract agreement will not
obligate the purchase contract agent to exercise any discretionary actions in
connection with a default under the terms of the Corporate Units and Treasury
Units or the purchase contract agreement.

   The purchase contract agreement will contain provisions limiting the
liability of the purchase contract agent. The purchase contract agreement will
contain provisions under which the purchase contract agent may resign or be
replaced. This resignation or replacement would be effective upon the
acceptance of appointment by a successor.

   JPMorgan Chase Bank maintains commercial banking relationships with us.

Information Concerning the Collateral Agent

   Bank One Trust Company, N.A. will be the collateral agent. The collateral
agent will act solely as our agent and will not assume any obligation or
relationship of agency or trust for or with any of the holders of the Corporate
Units or Treasury Units except for the obligations owed by a pledgee of
property to the owner of the property under the pledge agreement and applicable
law.

   The pledge agreement will contain provisions limiting the liability of the
collateral agent. The pledge agreement will contain provisions under which the
collateral agent may resign or be replaced. This resignation or replacement
would be effective upon the acceptance of appointment by a successor.

   Bank One Trust Company, N.A. maintains commercial banking relationships with
us.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

   The following summary describes the material United States federal income
tax consequences of the purchase, ownership and disposition of the Equity
Units, Duke Capital senior notes, and Duke Energy common stock acquired under
the purchase contracts as of the date of this prospectus supplement.

   Except where otherwise stated, this summary deals only with Equity Units,
Duke Capital senior notes, and Duke Energy common stock held as capital assets
by a holder who:

  .  is a United States person (as defined below), and

  .  purchases the Equity Units upon original issuance at their original issue
     price.

   A "United States person" is a holder who is one of the following:

  .  a citizen or resident of the United States;

  .  a corporation, partnership or other entity created or organized in or
     under the laws of the United States or any political subdivision of the
     United States;

  .  an estate the income of which is subject to United States federal income
     taxation regardless of its source; or

  .  a trust if it (1) is subject to the primary supervision of a court within
     the United States and one or more United States persons have the authority
     to control all substantial decisions of the trust, or (2) has a valid
     election in effect under applicable United States Treasury regulations to
     be treated as a United States person.

   The tax treatment of a holder may vary depending on such holder's particular
situation. This summary does not address all the tax consequences that may be
relevant to holders that are subject to special tax treatment, such as:

  .  dealers in securities or currencies;

  .  financial institutions;

  .  tax-exempt investors;

  .  traders in securities that elect to use a mark-to-market method of
     accounting for their securities holdings;

  .  insurance companies;

  .  real estate investment companies;

  .  regulated investment companies;

  .  persons holding Corporate Units, Treasury Units, Duke Capital senior
     notes, or Duke Energy common stock as part of a hedging, conversion,
     integrated or constructive sale transaction;

  .  persons holding Corporate Units, Treasury Units, Duke Capital senior notes
     or Duke Energy common stock as part of a straddle;

  .  persons whose functional currency is not the United States dollar; or

  .  persons liable for alternative minimum tax.


   In addition, if a partnership holds Corporate Units, Treasury Units, Duke
Capital senior notes or Duke Energy common stock, the tax treatment of a
partner will generally depend upon the status of the partner and the activities
of the partnership. If an investor is a partner of a partnership holding the
above instruments, such investor should consult its tax advisors.

   This summary is based on the Internal Revenue Code of 1986, as amended
(which is referred to as the "Code"), the Treasury regulations promulgated
under the Code and administrative and judicial interpretations. These income
tax laws, regulations and interpretations, however, may change at any time. Any
change could be retroactive to the issuance date of the Equity Units.

                                     S-41



   No statutory, administrative or judicial authority directly addresses the
treatment of Equity Units or instruments similar to Equity Units for United
States federal income tax purposes. As a result, no assurance can be given that
the IRS or the courts will agree with the tax consequences described herein.
Each investor should consult its own tax advisor regarding the tax consequences
to such investor of the purchase, ownership and disposition of the Corporate
Units, Treasury Units, Duke Capital senior notes and Duke Energy common stock,
including the tax consequences under state, local, foreign and other tax laws.

Equity Units

  Allocation of Purchase Price

   A holder's acquisition will be treated as an acquisition of the Duke Capital
senior note and the purchase contract constituting the Equity Unit and, by
purchasing an Equity Unit, such holder will be deemed to have agreed to such
treatment. The purchase price of each unit will be allocated between the Duke
Capital senior note and the purchase contract in proportion to their respective
fair market values at the time of purchase. Such allocation will establish a
holder's initial tax basis in the Duke Capital senior note and the purchase
contract. Duke Capital will report the fair market value of each Duke Capital
senior note as $25.0 and the fair market value of each purchase contract as
$0.0. This position will be binding on each holder (but not on the IRS) unless
such holder explicitly discloses a contrary position on a statement attached to
such holder's timely filed United States federal income tax return for the
taxable year in which a unit is acquired. Thus, absent such disclosure, a
holder should allocate the purchase price for a unit in accordance with the
foregoing. The remainder of this discussion assumes that this allocation of the
purchase price will be respected for United States federal income tax purposes.

Duke Capital Senior Notes

  Accrual of Interest

   Because of the manner in which the interest rate on the Duke Capital senior
notes is reset, the notes will be classified as contingent payment debt
obligations under the Treasury regulations. All payments on the Duke Capital
senior notes including stated interest will be taken into account under these
Treasury regulations and actual cash payments of interest on the Duke Capital
senior notes will not be reported separately as taxable income. As discussed
more fully below, the effect of these Treasury regulations will be to:

  .  require each holder, regardless of its usual method of tax accounting, to
     use the accrual method with respect to the Duke Capital senior notes;

  .  possibly result in the accrual of original issue discount by each holder
     in excess of stated interest payments actually received by such holder; and

  .  generally result in ordinary rather than capital treatment of any gain,
     and to some extent loss, on the sale, exchange, or other disposition of
     the notes.

   Under the contingent payment debt rules, a holder will be required to
include original issue discount in income each year, regardless of its usual
method of tax accounting, based on the comparable yield of the Duke Capital
senior notes. In order to determine a holder's income, these rules require Duke
Capital to determine, as of the issue date, the comparable yield for the Duke
Capital senior notes. The comparable yield of the Duke Capital senior notes
will generally be the rate at which Duke Capital would issue a fixed rate debt
instrument with terms and conditions similar to the Duke Capital senior notes.

   Duke Capital is required to provide the comparable yield to the holders and,
solely for tax purposes, is also required to provide a projected payment
schedule that includes the actual interest payments on the Duke Capital senior
notes and estimates the amount and timing of contingent payments on the Duke
Capital senior notes. Duke Capital has determined that the comparable yield is
an annual rate of 5.04%, compounded quarterly. Based on the comparable yield,
the projected payment schedule per Duke Capital senior note is $0.2610 for the
period ending

                                     S-42



on February 16, 2002, $0.2700 for each subsequent quarter ending on or prior to
the initial remarketing date, $0.3780 for each quarter ending after the initial
remarketing date and $25.3780 at maturity. Under the fourth supplemental
indenture governing the Duke Capital senior notes, Duke Capital will agree, and
by acceptance of a beneficial interest in the Duke Capital senior notes each
holder will be deemed to have agreed, for United States federal income tax
purposes, to be bound by Duke Capital's determination of the comparable yield
and projected payment schedule.

   The comparable yield and the projected payment schedule are not provided for
any purpose other than the determination of each holder's interest accruals and
adjustments thereof in respect of the Duke Capital senior notes and do not
constitute a representation regarding the actual amount of the payment on a
Duke Capital senior note.

   The amount of original issue discount on a Duke Capital senior note for each
accrual period is determined by multiplying the comparable yield of the Duke
Capital senior note, adjusted for the length of the accrual period, by the Duke
Capital senior note's adjusted issue price at the beginning of the accrual
period, determined in accordance with the rules set forth in the contingent
payment debt regulations. The adjusted issue price of each Duke Capital senior
note at the beginning of each accrual period will equal $25.0, increased by any
original issue discount previously accrued on the Duke Capital senior note and
decreased by the fixed payments and by the contingent payments projected to be
made on the Duke Capital senior note. The amount of original issue discount so
determined is then allocated on a ratable basis to each day in the accrual
period that a holder held the Duke Capital senior note. Duke Capital is
required to provide information returns stating the amount of original issue
discount accrued on Duke Capital senior notes held of record by persons other
than corporations and other exempt owners.

   If after the remarketing date, the remaining amounts of principal and
interest payable on the Duke Capital senior notes differ from the payments set
forth on the foregoing projected payment schedule, negative or positive
adjustments reflecting such differences should be taken into account by a
holder as adjustments to interest income in a reasonable manner over the period
to which they relate.

Treasury Units

  Substitution of Treasury Security to Create Treasury Units

   If a holder delivers a Treasury security to the collateral agent in
substitution for the Duke Capital senior note, such holder generally will not
recognize gain or loss upon the delivery of the Treasury security or the
release of the Duke Capital senior note. Such holder will continue to include
in income any original issue discount with respect to the Duke Capital senior
notes and Treasury security, and such holder's tax basis in the Duke Capital
senior notes, Treasury security and the purchase contract will not be affected
by the delivery and release.

  Ownership of Treasury Securities

   Duke Capital and, by acquiring Treasury Units, each holder agrees to treat
such holder as the owner, for United States federal, state and local income and
franchise tax purposes, of the Treasury security that is a part of the Treasury
Units beneficially owned by such holder. Such holder's initial tax basis in the
Treasury security that is a part of the Treasury Units will be equal to the
amount paid for the Treasury security. In general, a holder will be required to
include in income each year that such holder holds a treasury security the
portion of the original issue discount or acquisition discount that accrues on
the Treasury security in such year.

  Substitution of Senior Notes to Recreate Corporate Units

   If a holder delivers Duke Capital senior notes to the collateral agent to
recreate Corporate Units, such holder generally will not recognize gain or loss
upon the delivery of the Duke Capital senior notes or the release of the

                                     S-43



Treasury security. Such holder will continue to take into account items of
income or deduction otherwise includible or deductible, respectively, with
respect to the Treasury security and the Duke Capital senior notes, and such
holder's tax basis in the Duke Capital senior notes, the Treasury security and
the purchase contract will not be affected by the delivery and release.

Purchase Contracts

  Purchase Contract Adjustment Payments

   There is no direct authority addressing the treatment of the purchase
contract adjustment payments under current law, and such treatment is unclear.
Purchase contract adjustment payments may constitute taxable income to a holder
of Equity Units when received or accrued, in accordance with the holder's
method of tax accounting. To the extent Duke Energy is required to file
information returns with respect to purchase contract adjustment payments, it
intends to report such payments as taxable income to each holder. Holders
should consult their own tax advisor concerning the treatment of purchase
contract adjustment payments, including the possibility that any such payment
may be treated as a loan, purchase price adjustment, rebate or payment
analogous to an option premium, rather than being includible in income on a
current basis. The treatment of purchase contract adjustment payments could
affect a holder's tax basis in a purchase contract or Duke Energy common stock
received under a purchase contract or the amount realized by a holder upon the
sale or disposition of Corporate Units or Treasury Units or the termination of
a purchase contract. See "--Acquisition of Duke Energy Common Stock Under a
Purchase Contract", "--Sale or Disposition of Corporate Units or Treasury
Units" and "--Termination of Purchase Contract".

  Acquisition of Duke Energy Common Stock Under a Purchase Contract

   A holder of an Equity Unit generally will not recognize gain or loss on the
purchase of Duke Energy common stock under a purchase contract, except with
respect to any cash paid in lieu of a fractional share of Duke Energy common
stock. Subject to the following discussion, a holder's aggregate initial tax
basis in the Duke Energy common stock received under a purchase contract
generally should equal (a) the purchase price paid for such Duke Energy common
stock, plus (b) such holder's tax basis in the purchase contract (if any), less
(c) the portion of such purchase price and tax basis allocable to the
fractional share. Purchase contract adjustment payments that were paid to a
holder in cash but were not includible in such holder's income should reduce
such holder's tax basis in the purchase contract or the shares of Duke Energy
common stock to be received thereunder. See "--Purchase Contract Adjustment
Payments". The holding period for Duke Energy common stock received under a
purchase contract will commence on the day acquired.

  Early Settlement of Purchase Contract

   A holder of Equity Units will not recognize gain or loss on the receipt of
such holder's proportionate share of the Duke Capital senior notes or Treasury
securities, upon early settlement of a purchase contract, and such holder will
have the same tax basis in such senior notes or Treasury securities, as the
case may be, as before such early settlement.

  Termination of Purchase Contract

   If a purchase contract terminates, a holder of an Equity Unit will recognize
capital gain or loss equal to the difference between the amount realized (if
any) upon such termination and such holder's adjusted tax basis (if any) in the
purchase contract at the time of such termination. Purchase contract adjustment
payments, if any, received by a holder but not includible in income by such
holder should either reduce such holder's tax basis in the purchase contract or
result in an amount realized on the termination of the purchase contract. See
"--Purchase Contract Adjustment Payments". Capital gains of individuals derived
in respect of capital assets held for more than one year are taxed at a maximum
rate of 20%. The deductibility of capital losses is subject to limitations.

                                     S-44



   A holder will not recognize gain or loss on the receipt of such holder's
proportionate share of the Duke Capital senior notes or Treasury securities
upon termination of the purchase contract and will have the same tax basis in
such senior notes or Treasury securities, as the case may be, as before such
termination. If the termination of the purchase contract occurs when the
purchase contract has a negative value, see "--Sale or Disposition of Corporate
Units or Treasury Units". Each holder should consult its own tax advisor
regarding the termination of the purchase contract when the purchase contract
has a negative value.

  Adjustment to Settlement Rate

   Holders of Equity Units might be treated as receiving a constructive
distribution from Duke Energy if (i) the settlement rate is adjusted and as a
result of such adjustment the proportionate interest of holders of Equity Units
in the assets or earnings and profits of Duke Energy is increased and (ii) the
adjustment is not made pursuant to a bona fide, reasonable anti-dilution
formula. An adjustment in the settlement rate would not be considered made
pursuant to such a formula if the adjustment were made to compensate a holder
for certain taxable distributions with respect to the Duke Energy common stock.
Thus under certain circumstances, an increase in the settlement rate might give
rise to a taxable dividend to a holder even though such holder would not
receive any cash related thereto.

Sale or Disposition of Corporate Units or Treasury Units

   Upon a disposition of Corporate Units or Treasury Units, a holder will be
treated as having sold, exchanged or disposed of the purchase contract and the
Duke Capital senior notes or Treasury securities, as the case may be, that
constitute such Corporate Units or Treasury Units. A holder generally will have
gain or loss equal to the difference between the portion of such holder's
proceeds allocable to the purchase contract and the Duke Capital senior notes
or Treasury securities, as the case may be, and such holder's respective
adjusted tax bases in the purchase contract and the Duke Capital senior notes
or Treasury securities. For purposes of determining gain or loss, a holder's
proceeds will not include an amount equal to accrued and unpaid interest on the
Treasury securities not previously included in income, which amount will be
treated as ordinary interest income. Further, to the extent a holder is treated
as having received an amount with respect to accrued or deferred purchase
contract adjustment payments, such amounts may be treated as ordinary income to
the extent not previously included in income. Alternatively, purchase contract
adjustment payments that a holder did not previously include in income could
either reduce such holder's tax basis in the purchase contract or result in an
increase of the amount realized on the disposition of the purchase contract.
See " --Purchase Contract Adjustment Payments".

   In the case of the purchase contracts and the Treasury securities, such gain
or loss generally will be capital gain or loss. Capital gains of individuals
derived in respect of capital assets held for more than one year are taxed at a
maximum rate of 20%. The deductibility of capital losses is subject to
limitations. If the disposition of Corporate Units or Treasury Units occurs
when the purchase contract has a negative value, a holder should be considered
to have received additional consideration for the Duke Capital senior notes or
Treasury securities in an amount equal to such negative value, and to have paid
such amount to be released from such holder's obligation under the purchase
contract. Each holder should consult its tax advisor regarding a disposition of
Corporate Units or Treasury Units at a time when the purchase contract has a
negative value.

   Gain on the sale, exchange or other disposition of a Duke Capital senior
note prior to and including the remarketing date generally will be treated as
ordinary income. Loss from the disposition of a Duke Capital senior note prior
to and including the remarketing date will be treated as ordinary loss to the
extent of a holder's prior net interest inclusions (reduced by the total net
negative adjustments previously allowed as an ordinary loss). Any loss in
excess of such amount will be treated as capital loss. Gain recognized on the
sale, exchange or other disposition of a Duke Capital senior note after the
remarketing date will be ordinary income to the extent attributable to the
excess, if any, of the present value of the total remaining principal and
interest payments due

                                     S-45



on the Duke Capital senior note over the total remaining payments set forth on
the projected payment schedule for such Duke Capital senior note. Any gain
recognized in excess of such amount and any loss recognized on such sale,
exchange or other disposition generally will be treated as capital gain or
loss. Capital gain of individuals derived in respect of capital assets held for
more than one year will be subject to tax at a maximum rate of 20%. The
deductibility of capital losses is subject to limitations.

   Special rules apply in determining the tax basis of a note. A holder's basis
in a note is generally increased by original issue discount such holder
previously accrued on the note, and reduced by the fixed payments and by the
contingent payments projected to be made.

Remarketing or Tax Event Redemption of the Duke Capital Senior Notes

   A remarketing or tax event redemption of the Duke Capital senior notes will
be a taxable event for holders of such senior notes which will be subject to
tax in the manner described above under "--Sale or Disposition of Corporate
Units or Treasury Units".

  Ownership of the Treasury Portfolio

   After the remarketing settlement date, a holder's Corporate Unit will
include a Treasury portfolio instead of a Duke Capital senior note. Duke Energy
and, by acquiring Corporate Units, each holder agree to treat such holder as
the owner, for United States federal, state and local income and franchise tax
purposes, of the Treasury portfolio that is a part of the Corporate Units
beneficially owned by such holder. Each holder's initial tax basis in its
applicable ownership interest of the Treasury portfolio will equal such
holder's pro rata portion of the amount paid by the remarketing agent for the
Treasury portfolio. Each holder's adjusted tax basis in the Treasury portfolio
will be increased by the amount of original issue discount included in income
with respect thereto and decreased by the amount of cash received in respect of
the Treasury portfolio.

  Interest Income and Original Issue Discount

   The Treasury portfolio will consist of stripped U.S. Treasury securities.
Following a remarketing of the Duke Capital senior notes, a holder of Corporate
Units will be required to treat its pro rata portion of each U.S. Treasury
security in the Treasury portfolio as a bond that was originally issued on the
date the collateral agent acquired the relevant U.S. Treasury securities and
that has original issue discount equal to the holder's pro rata portion of the
excess of the amounts payable on such U.S. Treasury securities over the value
of the U.S. Treasury securities at the time the collateral agent acquires them
on behalf of holders of Corporate Units. A holder, whether on the cash or
accrual method of tax accounting, will be required to include original issue
discount (other than original issue discount on short-term U.S. Treasury
securities as defined below) in income for United States federal income tax
purposes as it accrues on a constant yield to maturity basis. The amount of
such excess will constitute only a portion of the total amounts payable in
respect of the Treasury portfolio. Consequently, a portion of each scheduled
payment to holders will be treated as a return of such holders' investment in
the Treasury portfolio and will not be considered current income for United
States federal income tax purposes.

   In the case of any U.S. Treasury security with a maturity of one year or
less from the date of its issue (a "short-term U.S. Treasury Security"), in
general only accrual basis taxpayers will be required to include original issue
discount in income as it accrues. Unless such accrual basis holder elects to
accrue the original issue discount on a short-term U.S. Treasury security on a
constant yield to maturity basis, such original issue discount will be accrued
on a straight-line basis.

Non-United States Holders

   The following discussion applies only to Non-United States Holders. A holder
is a "Non-United States Holder" if such holder is not a United States person.
Special rules may apply to a holder if such holder is a "controlled foreign
corporation", "passive foreign investment company", "foreign personal holding
company" or in certain circumstances a U.S. expatriate, and such Non-U.S.
Holders should consult their own tax advisors.

                                     S-46



  United States Federal Withholding Tax

   The 30% United States federal withholding tax will not apply to any payment
of principal or interest (including original issue discount) on the Duke
Capital senior notes or Treasury securities provided that:

  .  a holder does not actually (or constructively) own 10% or more of the
     total combined voting power of all classes of Duke Capital's voting stock
     within the meaning of the Code and the Treasury regulations;

  .  a holder is not a controlled foreign corporation that is related to us
     through stock ownership;

  .  a holder is not a bank whose receipt of interest on the Duke Capital
     senior notes or Treasury securities is described in section 881(c)(3)(A)
     of the Code; and

  .  (a) a holder provides its name and address on an IRS Form W-8BEN (or other
     applicable form), and certifies, under penalty of perjury, that such
     holder is not a United States person, or (b) if a holder holds its
     Corporate Units, Treasury Units, Duke Capital senior notes or Treasury
     securities through certain foreign intermediaries, such holder satisfies
     the certification requirements of applicable United States Treasury
     regulations. Special certification requirements apply to certain
     Non-United States Holders that are pass-through entities rather than
     individuals.

   If a holder cannot satisfy the requirements described above, payments of
premium, if any, and interest (including original issue discount) made to such
holder will be subject to the 30% United States federal withholding tax, unless
such holder provides us with a properly executed (1) IRS Form W-8BEN (or other
applicable form) claiming an exemption from, or reduction in the rate of,
withholding under the benefit of an applicable tax treaty or (2) IRS Form
W-8ECI (or other applicable form) stating that interest paid on the Duke
Capital senior notes or Treasury securities is not subject to withholding tax
because it is effectively connected with a holder's conduct of a trade or
business in the United States.

   The 30% United States federal withholding tax will not apply to any gain
that a holder realizes on the sale, exchange, or other disposition of the
Corporate Units, Treasury Units, Treasury securities, Duke Capital senior notes
and Duke Energy common stock acquired under the purchase contract. However,
interest income including original issue discount and any gain treated as
ordinary income that a holder realizes on the sale, exchange or other
disposition of a Duke Capital senior note will be subject to withholding in
certain circumstances unless the conditions described in the four bullet points
above are satisfied.

   Duke Energy will generally withhold tax at a 30% rate on purchase contract
adjustment payments and dividends paid on the Duke Energy common stock acquired
under a purchase contract or such lower rate as may be specified by an
applicable income tax treaty. However, purchase contract adjustment payments or
dividends that are effectively connected with the conduct of a trade or
business by the Non-United States Holder within the United States and, where a
tax treaty applies, are attributable to a United States permanent establishment
of the Non-United States Holder, are not subject to the withholding tax,
provided the relevant certification requirements are satisfied, but instead are
subject to United States federal income tax, as described below.

   A Non-United States Holder of Duke Energy common stock or a purchase
contract who wishes to claim the benefit of an applicable treaty rate (and
avoid back-up withholding as discussed below) for dividends or purchase
contract adjustment payments, will be required to satisfy certain certification
and disclosure requirements described in the fourth bullet point above.

   A Non-United States Holder eligible for a reduced rate of United States
withholding tax on payments pursuant to an income tax treaty may obtain a
refund of any excess amounts withheld by filing an appropriate claim for refund
with the IRS.

  United States Federal Income Tax

   If a holder is engaged in a trade or business in the United States and
interest (including original issue discount) on the Duke Capital senior notes
or Treasury securities, dividends on the Duke Energy common stock,

                                     S-47



or to the extent they constitute taxable income, purchase contract adjustment
payments from the purchase contracts are effectively connected with the conduct
of that trade or business, such holder will be subject to United States federal
income tax on that interest, dividends or purchase contract adjustment payments
on a net income basis (although exempt from the 30% withholding tax), in the
same manner as if such holder were a United States person as defined under the
Code. Certain certification and disclosure requirements must be complied with
in order for effectively connected income to be exempt from withholding. In
addition, if a holder is a foreign corporation, such holder may be subject to a
branch profits tax equal to 30% (or lower applicable treaty rate) of such
holder's earnings and profits for the taxable year, subject to adjustments,
that are effectively connected with the conduct by such holder of a trade or
business in the United States. For this purpose, interest on the Duke Capital
senior notes or Treasury securities, dividends on the Duke Energy common stock
and, to the extent they constitute taxable income, the purchase contract
adjustment payments from the purchase contracts will be included in earnings
and profits.

   Any gain realized on the disposition of a Treasury security, Duke Capital
senior note, purchase contract or share of Duke Energy common stock generally
will not be subject to United States federal income tax unless (1) that gain
or income is effectively connected with the conduct of a trade or business by a
holder in the United States or (2) a holder is an individual who is present in
the United States for 183 days or more in the taxable year of that disposition,
and certain other conditions are met or (3) in the case of Corporate Units,
Treasury Units or Duke Energy common stock, Duke Energy is or has been a
"United States real property holding corporation" for United States federal
income tax purposes.

   An individual Non-United States Holder described in clause (1) above will be
subject to tax on the net gain derived from the sale under regular graduated
United States federal income tax rates. An individual Non-United States Holder
described in clause (2) above will be subject to a flat 30% tax on the gain
derived from the sale, which may be offset by United States source capital
losses (even though the individual is not considered a resident of the United
States). If a Non-U.S. Holder that is a foreign corporation falls under clause
(1) above, it will be subject to tax on its gain under regular graduated United
States federal income tax rates and, in addition, may be subject to the branch
profits tax equal to 30% of its effectively connected earnings and profits or
at such lower rate as may be specified by an applicable income tax treaty.

   Duke Energy has not determined whether it is a "United States real property
holding corporation" for United States federal income tax purposes. If Duke
Energy is or becomes a "United States real property holding corporation", so
long as the Duke Energy common stock continues to be regularly traded on an
established securities market, (1) a holder will not be subject to United
States federal income tax on the disposition of the Duke Energy common stock if
such holder holds or held (at any time during the shorter of the five year
period preceding the date of disposition or such holder's holding period) less
than or equal to five percent of the total outstanding shares of Duke Energy
common stock and (2) a holder will not be subject to United States federal
income tax on the disposition of the purchase contracts if on the day such
holder acquired the purchase contracts, the purchase contracts had a fair
market value less than five percent of the fair market value of all of the
purchase contracts.

  United States Federal Estate Tax

   A holder's estate will not be subject to United States federal estate tax on
the Duke Capital senior notes or Treasury securities beneficially owned by such
holder at the time of such holder's death, provided that (1) such holder does
not own 10% or more of the total combined voting power of all classes of Duke
Capital voting stock, within the meaning of the Code and United States Treasury
regulations, and (2) interest on those senior notes or
Treasury securities would not have been, if received at the time of such
holder's death, effectively connected with the conduct by such holder of a
trade or business in the United States. Duke Energy common stock acquired under
a purchase contract and owned by a holder at the time of such holder's death
will be subject to United

                                     S-48



States federal estate tax unless an applicable estate tax treaty provides
otherwise. Purchase contracts owned by a holder at the time of such holder's
death may be subject to United States federal estate tax unless an applicable
estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

  United States Holders

   In general, information reporting requirements will apply to payments on the
Corporate Units, Treasury Units, Duke Capital senior notes, Treasury
securities, and Duke Energy common stock made to a holder and to the proceeds
of the sale or other disposition of such instruments, unless such holder is an
exempt recipient such as a corporation. A backup withholding tax will apply to
such payments if a holder fails to provide a taxpayer identification number, a
certification of exempt status, or fail to report in full interest income.

  Non-United States Holders

   In general, no information reporting or backup withholding will be required
regarding payments on the Corporate Units, Treasury Units, Duke Capital senior
notes, Treasury securities, and Duke Energy common stock (except possibly with
respect to purchase contract adjustment payments) that Duke Energy and Duke
Capital make to a holder provided that Duke Energy and Duke Capital do not have
actual knowledge that such holder is a United States person and have received
from such holder the statement described above under "--United States Federal
Withholding Tax."

   In addition, no information reporting or backup withholding will be required
regarding the proceeds of the sale of Corporate Units, Treasury Units, Duke
Capital senior notes, Treasury securities, and Duke Energy common stock made
within the United States or conducted through certain United States financial
intermediaries if the payor receives the statement described above and does not
have actual knowledge that a holder is a United States person or such holder
otherwise establishes an exemption.

   Any amounts withheld under the backup withholding rules will be allowed as a
refund or a credit against a holder's United States federal income tax
liability provided the required information is furnished to the IRS.

                                     S-49



                             ERISA CONSIDERATIONS

   The following is a summary of certain considerations associated with the
acquisition, holding and disposition of Equity Units (and the securities
underlying such units) by employee benefit plans that are subject to Title I of
the U.S. Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
plans, individual retirement accounts and other arrangements that are subject
to Section 4975 of the Code or provisions under any federal, state, local,
non-U.S. or other laws or regulations that are similar to such provisions of
the Code or ERISA (collectively, "similar laws"), and entities whose underlying
assets are considered to include "plan assets" of such plans, accounts and
arrangements (each, a "plan").

General Fiduciary Matters

   ERISA and the Code impose certain duties on persons who are fiduciaries of a
plan subject to Title I of ERISA or Section 4975 of the Code and prohibit
certain transactions involving the assets of a plan and its fiduciaries or
other interested parties. Under ERISA and the Code, any person who exercises
any discretionary authority or control over the administration of such a plan
or the management or disposition of the assets of such a plan, or who renders
investment advice for a fee or other compensation to such a plan, is generally
considered to be a fiduciary of the plan.

   In considering an investment of a portion of the assets of any plan in the
Equity Units (and the securities underlying such units), a plan fiduciary
should determine whether the investment is in accordance with the documents and
instruments governing the plan and the applicable provisions of ERISA, the Code
or any similar law relating to a fiduciary's duties to the plan including,
without limitation, the prudence, diversification, delegation of control and
prohibited transaction provisions of ERISA, the Code and any of the applicable
similar laws.

   Any insurance company proposing to invest assets of its general account in
the securities should consider the extent that such investment would be subject
to the requirements of ERISA in light of the U.S. Supreme Court's decision in
John Hancock Mutual Life Insurance Co. v. Harris Trust and Savings Bank and
under any subsequent legislation or other guidance that has or may become
available relating to that decision, including the enactment of Section 401(c)
of ERISA by the Small Business Job Protection Act of 1996 and the regulations
promulgated thereunder.

Prohibited Transaction Issues

   Section 406 of ERISA and Section 4975 of the Code prohibit plans subject to
Title I of ERISA or Section 4975 of the Code from engaging in specified
transactions involving plan assets with persons or entities who are "parties in
interest," within the meaning of ERISA, or "disqualified persons," within the
meaning of Section 4975 of the Code, unless an exemption is available. A party
in interest or disqualified person who engages in a non-exempt prohibited
transaction may be subject to excise taxes and other penalties and liabilities
under ERISA and the Code. In addition, the fiduciary of a plan that engages in
such a non-exempt prohibited transaction may be subject to penalties and
liabilities under ERISA and the Code.

   The Equity Units (and the securities underlying such units) will be deemed
to constitute "plan assets" and the acquisition, holding and disposition of the
Equity Units (and the securities underlying such units) may constitute or
result in a direct or indirect prohibited transaction under Section 406 of
ERISA and/or Section 4975 of the Code, if Duke Energy, the seller or the
purchaser is a party in interest or disqualified person with respect to such
plan, unless an exemption is available. In this regard, the U.S. Department of
Labor (the "DOL") has issued prohibited transaction class exemptions, or
"PTCEs," that may apply to these transactions. These class exemptions include,
without limitation, PTCE 84-14 (respecting transactions determined by
independent qualified professional asset managers), PTCE 90-1 (respecting
insurance company pooled separate accounts), PTCE 91-38 (respecting bank
collective investment trust partnerships), PTCE 95-60 (respecting life insurance

                                     S-50



company general accounts), PTCE 96-23 (respecting transactions determined by
in-house asset managers), and PTCE 75-1 (respecting principal transactions by a
broker-dealer). However, there can be no assurance that all of the conditions
of any such exemptions will be satisfied.

   Accordingly, due to the complexities of these rules and the penalties that
may be imposed upon persons involved in nonexempt prohibited transactions, by
its purchase of the Equity Units (and the securities underlying such units),
each holder, and the fiduciary of any plan that is a holder, will be deemed to
have represented and warranted on each day from and including the date of its
purchase of the Equity Units (and the securities underlying such units) through
and including the date of disposition of the satisfaction of its obligation
under the purchase contract and the disposition of any such Equity Unit (and
any security underlying such unit) either (i) that it is not a plan or (ii)
that the acquisition, holding and the disposition of any Equity Unit (and any
security underlying such unit) by such holder does not and will not constitute
a prohibited transaction under ERISA or Section 4975 of the Code or other
similar laws unless an exemption is available with respect to such transactions
and the conditions of such exemption have been satisfied.

   In addition, no plan will be permitted to participate in the remarketing
program unless and until such plan provides the remarketing agent with
assurances, reasonable satisfactory to the remarketing agent, that such
participation in the remarketing program will not constitute a prohibited
transaction under ERISA or Section 4975 of the Code of other similar laws for
which an exemption is not available.

   Any plan or other entity whose assets include plan assets subject to ERISA,
Section 4975 of the Code or substantially similar federal, state or local law
should consult their advisors and/or counsel.

                                 UNDERWRITING

   Under the terms and subject to the conditions contained in an underwriting
agreement dated November 13, 2001, Morgan Stanley & Co. Incorporated (the
underwriter) has agreed to purchase, and we have agreed to sell to the
underwriter, all of the Corporate Units.

   The underwriter has agreed to purchase all of the Corporate Units sold under
the underwriting agreement if any of these Corporate Units are purchased.

   The underwriter is offering the Corporate Units, subject to prior sale,
when, as and if issued to and accepted by the underwriter, subject to approval
of legal matters by their counsel, including the validity of the Corporate
Units, and other conditions contained in the underwriting agreement, such as
the receipt by the underwriter of officers' certificates and legal opinions.
The underwriter reserves the right to withdraw, cancel or modify offers to the
public and to reject orders in whole or in part.

   We have granted an option to the underwriter to purchase up to an additional
4,500,000 Corporate Units at the public offering price less the underwriting
discount. The underwriter may exercise this option for 30 days from the date of
this prospectus supplement solely to cover any over-allotments. If the
underwriter's over-allotment option is exercised in full, the total price to
the public would be approximately $862.5 million, the total underwriting
discount would be approximately $21.6 million and the total proceeds, before
offering expenses, to Duke Capital would be approximately $840.9 million. The
expenses of the offering, not including the underwriting discount, are
estimated at $600,000.

   The underwriter has advised us that the underwriter proposes initially to
offer the Corporate Units to the public at the public offering price on the
cover page of this prospectus supplement and to dealers at that price less a
concession not in excess of $0.375 per Corporate Unit. After the public
offering, the public offering price, concession and discount may be changed.

   We and our executive officers have each agreed that subject to certain
exceptions, without the prior written consent of the underwriter, we and our
executive officers will not, during the 60-day period after the date of this
prospectus supplement:

   . offer, pledge, sell or contract to sell any Equity Units, purchase
     contracts, common stock or any similar securities or any security
     convertible into such securities,

   . sell any option or contract to purchase any Equity Units, purchase
     contracts, common stock or any similar securities or any security
     convertible into such securities,

   . purchase any option or contract to sell any Equity Units, purchase
     contracts, common stock or any similar securities or any security
     convertible into such securities,

   . grant any option, right or warrant for the sale of any Equity Units,
     purchase contracts, common stock or any similar securities or any security
     convertible into such securities,

   . lend or otherwise dispose of or transfer any Equity Units, purchase
     contracts, common stock or any similar securities or any security
     convertible into such securities, or

   . enter into any swap or other agreement that transfers, in whole or in
     part, the economic consequence of ownership of Equity Units, purchase
     contracts, common stock or any similar securities or any security
     convertible into such securities.

   This agreement does not apply to issuances under our employee or director
compensation plans or our employee or other investment plans. The underwriter,
in its sole discretion, may release any of the securities subject to these
lock-up agreements at any time without notice.

                                     S-52



   The Corporate Units are a new issue of securities with no established
trading market. We have applied to have the Corporate Units listed on the NYSE.
We have been advised by the underwriter that it intends to make a market in the
securities, but they are not obligated to do so and may discontinue
market-making at any time without notice. We can provide no assurance as to the
liquidity of, or any trading market for, the securities.

   This prospectus supplement, as amended or supplemented, may be used by the
remarketing agent for remarketing or upon early settlement or cash settlement
of the purchase contracts.

   Until the distribution of the Corporate Units offered hereby is completed,
SEC rules may limit the underwriter and any selling group members from bidding
for or purchasing the Corporate Units or shares of our common stock. However,
the underwriter may engage in transactions that stabilize the price of the
Corporate Units or our common stock, such as bids or purchases that peg, fix or
maintain the price of the Corporate Units or our common stock.

   In connection with the offering, the underwriter may make short sales of our
Corporate Units. Short sales involve the sale by the underwriter, at the time
of the offering, of a greater number of Corporate Units than the underwriter is
required to purchase in the offering. Covered short sales are sales made in an
amount not greater than the over-allotment option. The underwriter may close
out any covered short position by either exercising the over-allotment option
or purchasing Corporate Units in the open market. In determining the source of
Corporate Units to close out the covered short position, the underwriter will
consider, among other things, the price of Corporate Units available for
purchase in the open market as compared to the price at which they may purchase
the Corporate Units through the over-allotment option. Naked short sales are
sales in excess of the over-allotment option. The underwriter must close out
any naked short position by purchasing Corporate Units in the open market. A
naked short position is more likely to be created if the underwriter is
concerned that there may be downward pressure on the price of the Corporate
Units or our common stock in the open market after pricing that could adversely
affect investors who purchase in the offering. Similar to other purchase
transactions, the purchases by the underwriter to cover syndicate short
positions may have the effect of raising or maintaining the market price of the
Corporate Units and our common stock or preventing or retarding a decline in
the market price of the Corporate Units and our common stock. As a result, the
prices of the Corporate Units and our common stock may be higher than they
would otherwise be in the absence of these transactions.

   Neither we nor the underwriter make any representation or prediction as to
the direction or magnitude of any effect that the transactions described above
may have on the price of the Corporate Units or our common stock. In addition,
neither we nor the underwriter make any representation that the underwriter
will engage in these transactions or that these transactions, once commenced,
will not be discontinued without notice.

   We have agreed to indemnify the underwriter against certain liabilities,
including liabilities under the Securities Act of 1933, as amended, or if
indemnification is not allowed, to contribute to payments the underwriter may
be required to make because of those liabilities.

   In the ordinary course of business, the underwriter and its affiliates have
provided financial advisory, investment banking and general financing and
banking services to us and certain of our affiliates for customary fees.

                                    EXPERTS

   The consolidated financial statements and the related financial statement
schedules incorporated in this prospectus supplement by reference from our
annual report on Form 10-K for the year ended December 31, 2000 have been
audited by Deloitte & Touche LLP, independent auditors, as stated in their
report, which is incorporated herein by reference, and have been so

authority as experts in accounting and auditing.

                                 LEGAL MATTERS

   Certain legal matters with respect to the offering of the securities will be
passed on for us by Edward M. Marsh, Jr., Esq., who is our Deputy General
Counsel and Assistant Secretary, and Simpson Thacher & Bartlett, New York, New
York and for the underwriter by Sidley Austin Brown & Wood LLP, New York, New
York. In rendering their opinions, Simpson Thacher & Bartlett and Sidley Austin
Brown & Wood LLP will rely upon Mr. Marsh as to all matters of North Carolina
law. As of November 1, 2001, Mr. Marsh owned 8,764 shares of our common stock
or common stock units and options to purchase 27,450 shares, none of which were
exercisable.

                                USE OF PROCEEDS

   Unless Duke Energy states otherwise in the accompanying prospectus
supplement, Duke Energy intends to use the net proceeds from the sale of any
offered securities:

   . to redeem or purchase from time to time presently outstanding securities
     when it anticipates those transactions will result in an overall cost
     savings;

   . to repay maturing securities;

   . to finance its ongoing construction program; or

   . for general corporate purposes.

   The proceeds from the sale of Preferred Securities by a Trust will be
invested in Junior Subordinated Notes issued by Duke Energy. Except as Duke
Energy may otherwise describe in the related prospectus supplement, Duke Energy
expects to use the net proceeds from the sale of such Junior Subordinated Notes
to the applicable Trust for the above purposes.

                                  THE TRUSTS

   Duke Energy formed each Trust as a statutory business trust under Delaware
law. Each Trust's business is defined in a trust agreement executed by Duke
Energy, 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 Energy, 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 Energy 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 Energy 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 Energy 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 Energy
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 Energy for financial
reporting purposes. Accordingly, Duke Energy's consolidated financial
statements will include the accounts of each Trust. The Preferred Securities,
along with other trust preferred securities that Duke Energy guarantees on an
equivalent basis, will be presented as a separate line item in Duke Energy's
consolidated balance sheets, entitled "Guaranteed Preferred Beneficial
Interests in Subordinated Notes of Duke Energy Corporation or Subsidiaries."
Duke Energy 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 Energy will issue the Senior Notes in one or more series under its
Senior Indenture dated as of September 1, 1998 between Duke Energy 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 Energy's other unsecured and unsubordinated
indebtedness. The First and Refunding Mortgage Bonds are effectively senior to
the Senior Notes to the extent of the value of the properties securing them. As
of March 31, 2001, there were approximately $1,568,000,000 of First and
Refunding Mortgage Bonds outstanding.

   Duke Energy conducts its non-electric operations, and certain of its
electric operations outside its service area in the Carolinas, through
subsidiaries. Accordingly, its ability to meet its obligations under the Senior
Notes is partly 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 Energy. In addition, the rights that Duke Energy 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 of Duke Energy's subsidiaries
have incurred substantial amounts of debt in the expansion of their businesses,
and Duke Energy 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
Energy may issue under it. Duke Energy 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
Energy engages in a highly leveraged transaction.

Provisions Applicable to Particular Series

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

   . the total principal amount of the Senior Notes of the series;

   . the date or dates on which principal is payable or the method for

   . 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;

     dollars;

   . if payments may be made, at Duke Energy'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

     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 Energy states otherwise in the applicable prospectus supplement,
Duke Energy 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 Energy 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 or agency maintained by Duke Energy
for such purpose.

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

   Duke Energy 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 Energy 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 securities. Duke Energy 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 Energy 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 Energy;

   . the Senior Indenture Trustee; or

   . an agent of either of them.

Redemption

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

                                      7



redemption. Unless Duke Energy 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 Energy will not be required to redeem those
Senior Notes.

   Duke Energy 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 Energy 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 Energy's obligations under the Senior Indenture and the Senior
Notes issued under it, and Duke Energy 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 Energy under the Senior Indenture, and Duke Energy
will be relieved of its obligations under the Senior Indenture and the Senior
Notes.

Modification; Waiver

   Duke Energy 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 Energy 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 Energy's compliance with
certain restrictive provisions of the Senior Indenture, including the 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

                                      8



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 Energy 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 Energy 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
     Energy written notice of the default; and

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

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 Energy has initiated and is diligently pursuing
corrective action.

   Duke Energy 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 Energy 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 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

                                      9



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 Energy 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 Energy 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 Energy'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 Energy 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 Energy may,
however, change or add paying agents or approve a change in the office through
which a paying agent acts.

   Any money that Duke Energy 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 Energy
at its request. After repayment to Duke Energy, holders should look only to
Duke Energy for those payments.

Negative Pledge

   While any of the Senior Notes remain outstanding, Duke Energy will not
create, or permit to be created or to exist, any mortgage, lien, pledge,
security interest or other encumbrance upon any of its property, whether owned
on or acquired after the date of the Senior Indenture, to secure any
indebtedness for borrowed money of Duke Energy, 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 Energy acquired after
     the date of the Senior Indenture;

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

   . mortgages, liens, pledges, security interests or other encumbrances upon
     any property of Duke Energy that existed on the date of the initial
     issuance of the Senior Notes;

                                      10



   . 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 Energy 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 Energy;

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

   . Bonds issued or to be issued from time to time under Duke Energy's First
     and Refunding Mortgage, and the "permitted liens" specified in Duke
     Energy's First and Refunding Mortgage;

   . indebtedness which Duke Energy may issue in connection with its
     consolidation or merger with or into any other entity, which may be its
     affiliate, 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 Energy is required to assume in
     connection with a consolidation or merger of that entity, with respect to
     which any property of Duke Energy is subjected to a mortgage, lien,
     pledge, security interest or other encumbrance;

   . mortgages, liens, pledges, security interests or other encumbrances upon
     any property that Duke Energy acquired, constructed, developed or improved
     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 Energy 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 Energy may create or assume any other mortgage, lien, pledge,
security interest or other encumbrance not excepted in the Senior Indenture
without Duke Energy equally and ratably securing the Senior Notes, if
immediately after that creation or assumption, the principal amount of
indebtedness for borrowed money of Duke Energy that all such other mortgages,
liens, pledges, security interests and other encumbrances secure does not
exceed an amount equal to 10% of Duke Energy's common stockholders' equity as
shown on its

                                      11



consolidated balance sheet for the accounting period occurring immediately
before the creation or assumption of that mortgage, lien, pledge, security
interest or other encumbrance.

Defeasance and Covenant Defeasance

   The Senior Indenture provides that Duke Energy 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 Energy 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.

   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 Energy 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 Energy 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 is also the
trustee under Duke Energy's Subordinated Indenture and the trustee under Duke
Energy's First and Refunding Mortgage. Duke Energy 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 Energy 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.

                                      12



                 DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES

   Duke Energy will issue the Junior Subordinated Notes in one or more series
under its Subordinated Indenture dated as of December 1, 1997 between Duke
Energy 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 Energy and
are junior in right of payment to "Senior Indebtedness" of Duke Energy. You may
find a description of the subordination provisions of the Junior Subordinated
Notes, including a description of Senior Indebtedness of Duke Energy, under
"Subordination."

   Duke Energy conducts its non-electric operations, and certain of its
electric operations outside its service area in the Carolinas, through
subsidiaries. Accordingly, its ability to meet its obligations under the Junior
Subordinated Notes is partly 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 Energy. In addition, the rights that Duke Energy
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 of Duke
Energy's subsidiaries have incurred substantial amounts of debt in the
expansion of their businesses and Duke Energy 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 Energy may issue under it. Duke
Energy 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 Energy 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 Energy 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;

                                      13



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

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

   . any obligation that Duke Energy 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 Energy'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
     Energy'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 Energy states otherwise in the applicable prospectus supplement,
Duke Energy 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 Energy 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 Energy for such purpose.

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

   Duke Energy 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 supplement will
describe special United States federal income tax and any other considerations
applicable to

                                      14



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 Energy 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 Energy 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 Energy 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 Energy;

   . the Subordinated Indenture Trustee;

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

   . any agent of any of them.

                                      15



Redemption

   Provisions relating to the redemption of Junior Subordinated Notes will be
set forth in the applicable prospectus supplement. Unless Duke Energy states
otherwise in the applicable prospectus supplement, Duke Energy 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 Energy 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 Energy 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 Energy's obligations under the Subordinated
Indenture and the Subordinated Notes, including the Junior Subordinated Notes,
and Duke Energy 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 Energy under the Subordinated Indenture, and Duke Energy
will be relieved of its obligations under the Subordinated Indenture and any
Subordinated Notes, including the Junior Subordinated Notes.

Modification; Waiver

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

   The holders of a majority in principal amount of the outstanding Junior
Subordinated Notes of any series may waive, for that series, Duke Energy's
compliance with certain restrictive provisions of the Subordinated

                                      16



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 Energy 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 Energy 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 Energy 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 Energy written notice of the default; and

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

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 Energy has initiated and is
diligently pursuing corrective action.

   Duke Energy 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 Energy 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.

   In the case of Junior Subordinated Notes issued to a Trust, a holder of
Preferred Securities may institute a legal proceeding directly against Duke
Energy, without first instituting a legal proceeding against the Property

                                      17



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 Energy 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 Energy
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 Energy'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 Energy 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 Energy may, however, change or add paying agents or approve a
change in the office through which a paying agent acts.

   Any money that Duke Energy 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 Energy at its request. After repayment to Duke Energy, holders should look
only to Duke Energy for those payments.

Defeasance and Covenant Defeasance

   The Subordinated Indenture provides that Duke Energy 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

                                      18



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

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

   . 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

                                      19



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 Energy may issue. As of March 31, 2001, Duke Energy's Senior
Indebtedness totaled approximately $4,000,000,000.

Concerning the Subordinated Indenture Trustee

   The Chase Manhattan Bank is the Subordinated Indenture Trustee and is also
the Senior Indenture Trustee and the trustee under Duke Energy's First and
Refunding Mortgage. Duke Energy 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 Energy 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.

                                      20



             DESCRIPTION OF THE FIRST AND REFUNDING MORTGAGE BONDS

   Duke Energy will issue the First and Refunding Mortgage Bonds in one or more
series under its First and Refunding Mortgage, dated as of December 1, 1927, to
The Chase Manhattan Bank, as Trustee, as supplemented and amended. The First
and Refunding Mortgage is sometimes called the "Mortgage" and the First and
Refunding Mortgage Bonds are sometimes called the "Bonds" in this prospectus.
The trustee under the Mortgage is sometimes called the "Bond Trustee" in this
prospectus. The Mortgage is an exhibit to the registration statement, of which
this prospectus is a part.

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

General

   The amount of Bonds which Duke Energy may issue under the Mortgage is
unlimited. Duke Energy's Board of Directors will determine the terms of each
series of Bonds, including denominations, maturity, interest rate and payment
terms and whether the series will have redemption or sinking fund provisions.

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

   The Bonds will be issuable in denominations of $1,000 and multiples of
$1,000, unless Duke Energy states otherwise in the applicable prospectus
supplement. The Bonds will be exchangeable for an equivalent principal amount
of Bonds of other authorized denominations of the same series.

   The prospectus supplement for a particular series of Bonds will describe the
maturity, interest rate and payment terms of those Bonds and any relevant
redemption or sinking fund provisions.

Security

   The Mortgage creates a continuing lien to secure the payment of principal
and interest on the Bonds. All the Bonds are equally and ratably secured
without preference, priority or distinction. The lien of the Mortgage covers
substantially all of Duke Energy's properties, real, personal and mixed, and
Duke Energy's franchises, including properties acquired after the date of the
Mortgage, with certain exceptions. Those exceptions include cash, accounts
receivable, inventories of materials and supplies, merchandise held for sale,
securities that Duke Energy holds, certain after-acquired property not useful
in Duke Energy's electric business, certain after-acquired franchises and
certain after-acquired non-electric properties.

   The lien of the Mortgage is subject to certain permitted liens and to liens
that exist upon properties that Duke Energy acquired after it entered into the
Mortgage to the extent of the amounts of prior lien bonds secured by those
properties (not, however, exceeding 75% of the cost or value of those
properties) and additions to those properties. "Prior lien bonds" are bonds or
other indebtedness that are secured at the time of acquisition by a lien upon
property that Duke Energy acquires after the date of the Mortgage that becomes
subject to the lien of the Mortgage.

Issuance of Additional Bonds

   If Duke Energy satisfies the conditions in the Mortgage, the Bond Trustee
may authenticate and deliver additional Bonds in an aggregate principal amount
not exceeding:

   . the amount of cash that Duke Energy has deposited with the Bond Trustee
     for that purpose;

                                      21



   . the amount of previously authenticated and delivered Bonds or refundable
     prior lien bonds that have been or are to be retired which, with certain
     exceptions, Duke Energy has deposited with the Bond Trustee for that
     purpose; or

   . 66 2/3% of the aggregate of the net amounts of additional property
     (electric) certified to the Bond Trustee after February 18, 1949.

   The Bond Trustee may not authenticate and deliver any additional Bonds under
the Mortgage, other than certain types of refunding Bonds, unless Duke Energy's
available net earnings for twelve consecutive calendar months within the
immediately preceding fifteen calendar months have been at least twice the
amount of the annual interest charges on all Bonds outstanding under the
Mortgage, including the Bonds proposed to be issued, and on all outstanding
prior lien bonds that the Bond Trustee does not hold under the Mortgage.

   Duke Energy may not apply to the Bond Trustee to authenticate and deliver
any Bonds (1) in an aggregate principal amount exceeding $26,000,000 on the
basis of additional property (electric) that Duke Energy acquired or
constructed prior to January 1, 1949 or (2) on the basis of Bonds or prior lien
bonds paid, purchased or redeemed prior to February 1, 1949. Duke Energy may
not certify any additional property (electric) which is subject to the lien of
any prior lien bonds for the purpose of establishing those prior lien bonds as
refundable if the aggregate principal amount of those prior lien bonds exceeds
66 2/3% of the net amount of the additional property that is subject to the
lien of such prior lien bonds.

Release Provisions

   The Mortgage permits Duke Energy to dispose of certain property and to take
other actions without the Bond Trustee releasing that property. The Mortgage
also permits the release of mortgaged property if Duke Energy deposits cash or
other consideration equal to the value of the mortgaged property to be
released. In certain events and within certain limitations, the Bond Trustee is
required to pay out cash that the Bond Trustee receives--other than for the
Replacement Fund or as the basis for issuing Bonds--upon Duke Energy's
application.

   Duke Energy may withdraw cash that it deposited with the Bond Trustee as the
basis for issuing Bonds in an amount equal to the principal amount of any Bonds
that it is entitled to have authenticated and delivered on the basis of
additional property (electric), on the basis of Bonds previously authenticated
and delivered or on the basis of refundable prior lien bonds.

Replacement Fund

   The Mortgage requires Duke Energy to deposit with the Bond Trustee annually,
for the Replacement Fund established under the Mortgage, the sum of the
"replacement requirements" for all years beginning with 1949 and ending with
the last calendar year preceding the deposit date, less certain deductions.
Those deductions are (1) the aggregate original cost of all fixed property
(electric) retired during that time period, not exceeding the aggregate of the
gross amounts of additional property (electric) that Duke Energy acquired or
constructed during the same period, and (2) the aggregate amount of cash that
Duke Energy deposited with the Bond Trustee up to that time, or that Duke
Energy would have been required to deposit except for permitted reductions,
under the Replacement Fund.

   The "replacement requirement" for any year is 2 1/2% of the average "amount
of depreciable fixed property" (electric) owned by Duke Energy at the beginning
and end of that year, not exceeding, however, the amount Duke Energy is
permitted to charge as an operating expense for depreciation or retirement by
any governmental authority, or the amount deductible as depreciation or similar
expense for federal income tax purposes. The "amount of depreciable fixed
property" (electric) is the amount by which the sum of $192,913,385 plus the
aggregate gross amount of all depreciable additional property (electric) that
Duke Energy acquired or constructed from January 1, 1949 to the date as of
which such amount is determined exceeds the original cost of all of Duke

                                      22



Energy's depreciable fixed property (electric) retired during that period or
released from the lien of the Mortgage.

   Duke Energy may reduce the amount of cash at any time required to be
deposited in the Replacement Fund and may withdraw any cash that it previously
deposited that is held in the Replacement Fund:

   . in an amount equal to 150% of the principal amount of Bonds previously
     authenticated and delivered under the Mortgage, or refundable prior lien
     bonds, deposited with the Bond Trustee and on the basis of which Duke
     Energy would otherwise have been entitled to have additional Bonds
     authenticated and delivered; and

   . in an amount equal to 150% of the principal amount of Bonds which Duke
     Energy would otherwise be entitled to have authenticated and delivered on
     the basis of additional property (electric).

   Upon Duke Energy's application, the Bond Trustee will apply cash that Duke
Energy deposited in the Replacement Fund and has not previously withdrawn to
the payment, purchase or redemption of Bonds issued under the Mortgage or to
the purchase of refundable prior lien bonds.

   Duke Energy has never deposited any cash with the Bond Trustee for the
Replacement Fund. If Duke Energy deposits any cash in the future, it has agreed
not to apply that cash to the redemption of the Bonds as long as any Bonds then
outstanding remain outstanding.

Amendments of the Mortgage

   Duke Energy may amend the Mortgage with the consent of the holders of 66
2/3% in principal amount of the Bonds, except that no such amendment may:

   . affect the terms of payment of principal at maturity or of interest or
     premium on any Bond;

   . affect the rights of Bondholders to sue to enforce any such payment at
     maturity; or

   . reduce the percentage of Bonds required to consent to an amendment.

   No amendment may affect the rights under the Mortgage of the holders of less
than all of the series of Bonds outstanding unless the holders of 66 2/3% in
principal amount of the Bonds of each series affected consent to the amendment.

   The covenants included in the supplemental indenture for any series of Bonds
to be issued will be solely for the benefit of the holders of those Bonds. Duke
Energy may modify any such covenant only with the consent of the holders of 66
2/3% in principal amount of those Bonds outstanding, without the consent of
Bondholders of any other series.

Events of Default

   The Bond Trustee may, and at the written request of the holders of a
majority in principal amount of the outstanding Bonds will, declare the
principal of all outstanding Bonds due when any event of default under the
Mortgage occurs. The holders of a majority in principal amount of the
outstanding Bonds may, however, waive the default and rescind the declaration
if Duke Energy cures the default.

   Events of default under the Mortgage include:

   . default in the payment of principal;

   . default for 60 days in the payment of interest;

   . default in the performance of any other covenant in the Mortgage
     continuing for 60 days after the Bond Trustee or the holders of not less
     than 10% in principal amount of the Bonds then outstanding give notice of
     the default; and

                                      23



   . certain bankruptcy or insolvency events with respect to Duke Energy.

   Duke Energy provides a statement by certain of its officers each year to the
Bond Trustee stating whether it has complied with the covenants of the Mortgage.

Concerning the Bond Trustee

   The Chase Manhattan Bank is the Bond Trustee and is also the Senior
Indenture Trustee and the Subordinated Indenture Trustee. Duke Energy 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 Energy and of certain of its affiliates are outstanding.

   The Bond Trustee is under no obligation to exercise any of its powers at the
request of any of the holders of the Bonds unless those Bondholders have
offered to the Bond Trustee security or indemnity satisfactory to it against
the cost, expenses and liabilities it might incur as a result. The holders of a
majority in principal amount of the Bonds outstanding may direct the time,
method and place of conducting any proceeding for any remedy available to the
Bond Trustee, or the exercise of any trust or power of the Bond Trustee. The
Bond Trustee will not be liable for any action that it takes or omits to take
in good faith in accordance with any such direction.

                        DESCRIPTION OF THE COMMON STOCK

   The following description of Duke Energy's Common Stock is only a summary
and is not intended to be comprehensive. For additional information you should
refer to the applicable provisions of the North Carolina Business Corporation
Act and Duke Energy's Restated Articles of Incorporation (Articles) and
By-Laws. The Articles and By-Laws are exhibits to the registration statement,
of which this prospectus is a part.

General

   Duke Energy is authorized to issue up to 1,000,000,000 shares of Common
Stock. At March 31, 2001, 771,274,516 shares of Common Stock were outstanding.
Duke Energy is also authorized to issue up to 12,500,000 shares of Preferred
Stock, 10,000,000 shares of Preferred Stock A and 1,500,000 shares of
Preference Stock. At March 31, 2001, 2,284,984 shares of Preferred Stock,
2,057,185 shares of Preferred Stock A and no shares of Preference Stock were
outstanding. The Preferred Stock, Preferred Stock A and Preference Stock
together are sometimes called the "Preferred Stocks."

Dividends

   Holders of Common Stock are entitled to such dividends as may be declared
from time to time by the Board of Directors from legally available funds but
only if full dividends on all outstanding series of the Preferred Stocks for
the then current and all prior dividend periods and any required sinking fund
payments with respect to any outstanding series of such securities have been
paid or provided for.

Voting Rights

   Subject to the rights, if any, of the holders of the Preferred Stocks which
may be outstanding or as otherwise provided by law, the holders of Common Stock
have exclusive voting rights, each share being entitled to one vote. Holders of
Common Stock have noncumulative voting rights, which means that the holders of
more than 50% of the shares voting for the election of directors can elect 100%
of the directors and the holders of the remaining shares voting for the
election of directors will not be able to elect any directors.

   Whenever dividends on any part of any outstanding Preferred Stock or
Preferred Stock A are in arrears in an amount equivalent to the total dividends
required to be paid on that Preferred Stock or Preferred Stock A in any period
of 12 calendar months, the holders of the Preferred Stock as a class have the
exclusive right to elect a majority of the authorized number of directors and
the holders of the Preferred Stock A as a class have the exclusive right to
elect two directors. Those rights cease whenever Duke Energy pays all accrued
and unpaid dividends in full. Whenever six quarterly dividends on any
outstanding series of the Preference Stock are in arrears or any required
sinking fund payments are in default, the holders of the Preference Stock as a
class have the exclusive right to elect two directors. This right ceases
whenever all dividends and required sinking fund obligations in default have
been paid in full or provided for. In addition, the consent of the holders of
specified percentages of any outstanding Preferred Stock, Preferred Stock A or
Preference Stock, or some or all of the holders of such classes, is required in
connection with certain increases in authorized amounts of or changes in stock
senior to the Common Stock or in connection with any sale of substantially all
of Duke Energy's assets or certain mergers.

Rights Upon Liquidation

   The holders of Common Stock are entitled in liquidation to share ratably in
the assets of Duke Energy after payment of all debts and liabilities and after
required preferential payments to the holders of outstanding Preferred Stocks.

Miscellaneous

   The outstanding shares of Common Stock are, and the shares of Common Stock
sold hereunder will be, upon payment for them, fully paid and nonassessable.
Holders of Common Stock have no preemptive rights and

                                      25



no conversion rights. The Common Stock is not subject to redemption and is not
entitled to the benefit of any sinking fund provisions.

Transfer Agent and Registrar

   Duke Energy acts as transfer agent and registrar for the Common Stock.

Preference Stock Purchase Rights

   Each share of Common Stock has attached to it a Preference Stock Purchase
Right. The Rights initially are represented only by the certificates for the
shares of Common Stock and will not trade separately from those shares unless
and until:

   . ten days after it is publicly announced that a person or group (with
     certain exceptions) has acquired, or has obtained the right to acquire,
     the beneficial ownership of 15% or more of the outstanding Common Stock
     (an "acquiring person"); or

   . ten business days (or a later date determined by Duke Energy's Board of
     Directors) after the date a person or group commences, or public
     announcement is made that the person or group intends to commence, a
     tender or exchange offer that would result in the person or group becoming
     an acquiring person.

If and when the Rights separate, each Right will entitle the holder to purchase
1/10,000 of a share of Duke Energy's Series A Participating Preference Stock
for an exercise price that is presently $190.

   In the event that a person or group becomes an acquiring person, each Right
(except for Rights beneficially owned by the acquiring person or its
transferees, which Rights become void) will entitle its holder to purchase, for
the exercise price, a number of shares of Common Stock having a market value of
twice the exercise price. Also, if, after ten days following the date of the
announcement that a person or group has become an acquiring person:

   . Duke Energy is involved in a merger or similar form of business
     combination in which Duke Energy is not the surviving corporation or in
     which Duke Energy is the surviving corporation but the Common Stock is
     changed or exchanged; or

   . more than 50% of Duke Energy's assets or earning power is sold or
     transferred;

then each Right (except for voided Rights) will entitle its holder to purchase,
for the exercise price, a number of shares of common stock of the acquiring
company having a value of twice the exercise price. If any person or group
acquires from 15% to but excluding 50% of the outstanding Common Stock, Duke
Energy's Board of Directors may, at its option, exchange each outstanding Right
(except for those held by an acquiring person or its transferees) for one share
of Common Stock or 1/10,000 of a share of Series A Participating Preference
Stock.

   Duke Energy's Board of Directors may redeem the Rights for $0.01 per Right
prior to ten business days after the date of the public announcement that a
person or group has become an acquiring person.

   The Rights will not prevent a takeover of Duke Energy. However, the
existence of the Rights may cause substantial dilution to a person or group
that acquires 15% or more of the Common Stock unless the Board of Directors
first redeems those Rights.

                         Certain Anti-Takeover Matters

   Duke Energy's Articles and By-Laws include a number of provisions that may
have the effect of encouraging persons considering unsolicited tender offers or
other unilateral takeover proposals to negotiate with the Board of Directors
rather than pursue non-negotiated takeover attempts. Those provisions include:

                                      26



Classified Board of Directors; Removal of Directors; Vacancies

   Duke Energy's Articles provide for a Board of Directors divided into three
classes, with one class being elected each year to serve for a three-year term.
As a result, at least two annual meetings of shareholders may be required for
shareholders to change a majority of the Board of Directors. Duke Energy's
shareholders may remove directors only for cause. Vacancies and newly created
directorships on the Board of Directors may be filled only by the affirmative
vote of a majority of the directors remaining in office, and no decrease in the
number of directors may shorten the term of an incumbent director. The
classification of directors and the inability of shareholders to remove
directors without cause and to fill vacancies and newly created directorships
on the Board of Directors will make it more difficult to change the composition
of the Board of Directors, but will promote continuity of existing management.

Advance Notice Requirements

   Duke Energy's By-Laws establish advance notice procedures with regard to
shareholder proposals relating to the nomination of persons for election as
directors or new business to be brought before annual meetings of shareholders.
These procedures provide that shareholders must give timely notice of such
proposals in writing to the Secretary of Duke Energy. Generally, to be timely
with respect to an annual meeting of shareholders, notice must be received at
Duke Energy's principal executive offices not less than 90 days nor more than
120 days prior to the first anniversary date of the annual meeting for the
preceding year. The notice must contain certain information specified in the
By-Laws.

Special Meetings of Shareholders

   Neither the Articles nor the By-Laws of Duke Energy give shareholders the
right to call a special meeting of shareholders. The By-Laws provide that
special meetings of shareholders may be called only by the Board of Directors
or the Chairman of the Board.

Amendment of Certain Charter Provisions

   Duke Energy's Articles require the approval of not less than 80% of the
voting power of all outstanding shares of Common Stock to amend provisions
relating to the minimum and maximum size of the Board of Directors, the
classification of the Board of Directors, the removal of directors, the filling
of vacancies and newly created directorships on the Board of Directors and the
requirement that a decrease in the number of directors constituting the Board
of Directors may not shorten the term of any incumbent director. This amendment
provision will make it more difficult to dilute the anti-takeover effects of
Duke Energy's Articles and By-Laws.

                                      27



                  DESCRIPTION OF THE STOCK PURCHASE CONTRACTS
                         AND THE STOCK PURCHASE UNITS

   Duke Energy may issue stock purchase contracts representing contracts
obligating holders to purchase from Duke Energy, and Duke Energy to sell to the
holders, a specified number of shares of Common Stock (or a range of numbers of
shares pursuant to a predetermined formula) at a future date or dates. The
price per share of Common Stock may be fixed at the time the stock purchase
contracts are issued or may be determined by reference to a specific formula
set forth in the stock purchase contracts.

   The stock purchase contracts may be issued separately or as a part of units,
often known as stock purchase units, consisting of a stock purchase contract
and either:

   . Senior Notes, Junior Subordinated Notes or other debt securities of Duke
     Energy or one of its subsidiaries;

   . debt obligations of third parties, including U.S. Treasury securities; or

   . Preferred Securities or trust preferred securities issued by trusts, all
     of whose common securities are owned by Duke Energy or by subsidiaries of
     Duke Energy,

securing the holder's obligations to purchase the Common Stock under the stock
purchase contracts.

   The stock purchase contracts may require Duke Energy to make periodic
payments to the holders of the stock purchase units or vice versa, and such
payments may be unsecured or prefunded on some basis. The stock purchase
contracts may require holders to secure their obligations in a specified manner
and in certain circumstances Duke Energy may deliver newly issued prepaid stock
purchase contracts, often known as prepaid securities, upon release to a holder
of any collateral securing such holder's obligations under the original stock
purchase contract.

   The applicable prospectus supplement will describe the terms of any stock
purchase contracts or stock purchase units and, if applicable, prepaid
securities. The description in the applicable prospectus supplement will not
contain all of the information that you may find useful. For more information,
you should review the stock purchase contracts, the collateral arrangements and
depositary arrangements, if applicable, relating to such stock purchase
contracts or stock purchase units and, if applicable, the prepaid securities
and the document pursuant to which the prepaid securities will be issued. These
documents will be filed with the SEC promptly after the offering of such stock
purchase contracts or stock purchase units and, if applicable, prepaid
securities.


                                      28



                    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 Energy 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 Energy 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.

                                      29



                         DESCRIPTION OF THE GUARANTEES

   Duke Energy 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 Energy 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 Energy 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 Energy 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 Energy 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 to the payment of
distributions and other payments on the Preferred Securities only when the
Trust has sufficient funds legally and immediately available to make those
distributions or other payments.

   If Duke Energy 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.

                                      30



Subordination

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

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

   . equal in priority with Duke Energy's Preferred Stock and Preferred Stock A
     and similar guarantees; and

   . senior to Duke Energy's Common Stock.

   Duke Energy has Preferred Stock and Preferred Stock A outstanding that will
rank equal in priority with the Guarantees and 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 Energy, 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 Energy 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 Energy
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 Energy 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 Energy 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

                                      31



that Guarantee. Any holder of the related Preferred Securities may institute a
legal proceeding directly against Duke Energy 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, the Senior Indenture Trustee and
the Bond Trustee. Duke Energy 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 Energy 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 Energy 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 Energy 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.

                                      32



                             PLAN OF DISTRIBUTION

   Duke Energy and the Trusts may sell securities to one or more underwriters
or dealers for public offering and sale by them, or it may sell the securities
to investors directly or through agents. The prospectus supplement relating to
the securities being offered will set forth the terms of the offering and the
method of distribution and will identify any firms acting as underwriters,
dealers or agents in connection with the offering, including:

   . the name or names of any underwriters;

   . the purchase price of the securities and the proceeds to Duke Energy or
     the Trusts from the sale;

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

   . any public offering price;

   . any discounts or concessions allowed or reallowed or paid to dealers; and

   . any securities exchange or market on which the securities may be listed.

   Only those underwriters identified in the prospectus supplement are deemed
to be underwriters in connection with the securities offered in the prospectus
supplement.

   Duke Energy and the Trusts may distribute the securities from time to time
in one or more transactions at a fixed price or prices, which may be changed,
or at prices determined as the prospectus supplement specifies. Duke Energy may
sell securities through forward contracts or similar arrangements. In
connection with the sale of securities, underwriters, dealers or agents may be
deemed to have received compensation from Duke Energy in the form of
underwriting discounts or commissions and also may receive commissions from
securities purchasers for whom they may act as agent. Underwriters may sell the
securities to or through dealers, and such dealers may receive compensation in
the form of discounts, concessions or commissions from the underwriters or
commissions from the purchasers for whom they may act as agent.

   Duke Energy may sell the securities directly or through agents it designates
from time to time. Any agent involved in the offer or sale of the securities
covered by this prospectus, other than at the market offerings of common stock,
will be named in a prospectus supplement relating to such securities. At the
market offerings of common stock may be made by agents. Commissions payable by
Duke Energy to agents will be set forth in a prospectus supplement relating to
the securities being offered. Unless otherwise indicated in a prospectus
supplement, any such agents will be acting on a best-efforts basis for the
period of their appointment.

   Some of the underwriters, dealers or agents and some of their affiliates who
participate in the securities distribution may engage in other transactions
with, and perform other services for, Duke Energy and its subsidiaries or
affiliates in the ordinary course of business.

   Any underwriting or other compensation which Duke Energy pays to
underwriters or agents in connection with the securities offering, and any
discounts, concessions or commissions which underwriters allow to dealers, will
be set forth in the applicable prospectus supplement. Underwriters, dealers and
agents participating in the securities distribution may be deemed to be
underwriters, and any discounts and commissions they receive and any profit
they realize on the resale of the securities may be deemed to be underwriting
discounts and commissions under the Securities Act of 1933. Underwriters, and
their controlling persons, and agents may be entitled, under agreements entered
into with Duke Energy and the Trusts, to indemnification against certain civil
liabilities, including liabilities under the Securities Act of 1933.

                                      33

PROSPECTUS SUPPLEMENT
(To Prospectus dated May 10, 2001)

                                 $750,000,000

                           Duke Capital Corporation
                    a subsidiary of Duke Energy Corporation

                          4.32% Senior Notes due 2006

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

   We are offering the Senior Notes in connection with the issuance by Duke
Energy Corporation of 30,000,000 Duke Energy Corporation Equity Units as
described in the accompanying prospectus supplement and prospectus of Duke
Energy Corporation. Each Equity Unit will initially consist of a unit, referred
to as a Duke Energy Corporate Unit, which is comprised of a purchase contract
under which the holder agrees to purchase shares of common stock from Duke
Energy Corporation and a Senior Note in the principal amount of $25.

   Duke Energy has granted the underwriter a 30-day option to purchase up to
4,500,000 additional Duke Energy Corporate Units at the price to the public
less the underwriting discount as described in the accompanying prospectus
supplement and prospectus of Duke Energy Corporation to cover over-allotments,
which, if exercised, would involve the issuance by us of up to an additional
$112,500,000 of Senior Notes.

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

     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;

     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.

                DESCRIPTION OF THE 4.32% SENIOR NOTES DUE 2006

   The following description of the 4.32% Senior Notes due 2006 is only a
summary and is not intended to be comprehensive. The description should be read
together with the description set forth in the accompanying prospectus under
the caption "Description of the Senior Notes." In the event that information in
this prospectus supplement is inconsistent with information in the accompanying
prospectus, you should rely on this prospectus supplement.

General

   Reference in this prospectus supplement to Senior Notes refers to our 4.32%
Senior Notes due 2006. The Senior Notes will be issued as a separate series of
securities under our Senior Indenture.

   We are issuing the Senior Notes in connection with the issuance by Duke
Energy Corporation, our sole and direct parent, of Duke Energy Corporation
Equity Units. Each Equity Unit will initially consist of a unit, referred to as
a Duke Energy Corporate Unit, which is comprised of (1) a purchase contract
under which the holder agrees to purchase shares of Duke Energy common stock
from Duke Energy as provided therein and (2) a Senior Note in the principal
amount of $25. Holders of Duke Energy Corporate Units may substitute
zero-coupon Treasury securities for the Senior Notes that are part of their
Duke Energy Corporate Units under certain circumstances. In such an event, a
second type of Equity Unit, referred to as a Duke Energy Treasury Unit, is
created, with the Senior Note being released to the Equity Unit holder as a
result. Senior Notes that are part of Duke Energy Corporate Units will be
pledged to Duke Energy Corporation to secure the obligation that the Duke
Energy Corporate Unit holders have to purchase Duke Energy common stock. Duke
Energy Corporation has designated Bank One Trust Company, N.A. as collateral
agent to hold the pledged Senior Notes and any other pledged securities.

   The Senior Notes are limited in aggregate principal amount to $750,000,000
(or up to $862,500,000, if the underwriter's over-allotment option with respect
to the Equity Units is exercised in full). The entire principal amount of the
Senior Notes will mature and become due and payable, together with any accrued
and unpaid interest, on November 16, 2006, unless a tax event redemption has
occurred prior to November 16, 2006. Except for a tax event redemption, the
Senior Notes will not be redeemable by us. Senior Notes that are part of Duke
Energy Corporate Units will be issued in certificated form. The Senior Notes
will not be subject to a sinking fund provision.

Denominations; Transfer and Exchange

   The Senior Notes will be issuable in registered form, without coupons, in
denominations of $25 and integral multiples of $25, and may be transferred or
exchanged without service charge, but upon payment of any taxes or other
governmental charges payable in connection therewith.

Payments

   Payments on Senior Notes issued as a global security will be made to the
depositary, a successor depositary or, in the event that no depositary is used,
to a paying agent for the Senior Notes. Principal and interest with respect to
certificated Senior Notes will be payable, the transfer of the Senior Notes
will be registrable and Senior Notes will be exchangeable for Senior Notes of
other denominations of a like aggregate principal amount, at the office or
agency maintained by us for this purpose in the Borough of Manhattan, The City
of New York. However, at our option, payment of interest may be made by check
mailed to the address of the person entitled thereto as such address appears in
the security register or 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 payment. The Depository Trust Company will serve as the depositary
with

                                      S-4



respect to the Senior Notes, and JPMorgan Chase Bank will serve as the initial
paying agent, transfer agent and registrar for the Senior Notes. We may at any
time designate additional transfer agents and paying agents with respect to the
Senior Notes, and may remove any transfer agent, paying agent or registrar for
the Senior Notes. We will at all times be required to maintain a paying agent
and transfer agent for the Senior Notes in the Borough of Manhattan, The City
of New York.

   Any monies deposited with the Senior Indenture Trustee or any paying agent,
or held by us in trust, for the payment of principal of or interest on any
Senior Note and remaining unclaimed for two years after such principal or
interest has become due and payable will, at our request, be repaid to us or
released from trust, as applicable, and the holder of the Senior Note will
thereafter look, as a general unsecured creditor, only to us for the payment
thereof.

   The Senior Indenture does not contain provisions that afford holders of the
Senior Notes protection in the event of a highly leveraged transaction or other
similar transaction involving us that may adversely affect the holders.

Interest

   Each Senior Note will bear interest initially at the rate of 4.32% per year
from November 19, 2001, payable quarterly in arrears on February 16, May 16,
August 16 and November 16 of each year, commencing February 16, 2002. Interest
will be payable to the person in whose name the Senior Note is registered at
the close of business on the first day of the month in which the interest
payment date falls. In addition, because the Senior Notes are subject to the
contingent payment rules, Original Issue Discount, or OID, will accrue on the
Senior Notes.

   The interest rate on the Senior Notes will be reset in connection with the
initial remarketing or, if it fails, the next successful subsequent
remarketing. Unless a tax event redemption has occurred, the interest rate on
the Senior Notes will be reset to the reset rate described below under
"--Market Rate Reset" on the initial remarketing date, which will be three
business days immediately preceding August 16, 2004, and such reset rate will
become effective on August 16, 2004. However, if the initial remarketing fails,
the interest rate on the Senior Notes will not be reset on the initial
remarketing date and instead will be reset on the second remarketing date,
which will be three business days immediately preceding September 16, 2004, and
such reset rate will become effective on September 16, 2004. Similarly, if the
second remarketing fails, the interest rate on the Senior Notes will not be
reset on the second remarketing date and instead will be reset on the third
remarketing date, which will be three business days immediately preceding
October 16, 2004, and such reset rate will become effective on October 16,
2004. Finally, if the third remarketing fails, the interest rate on the Senior
Notes will not be reset on the third remarketing date and instead will be reset
on the fourth and final remarketing date, which will be three business days
immediately preceding November 16, 2004, and such reset rate will become
effective on November 16, 2004.

   The amount of interest payable for any period will be computed on the basis
of a 360-day year consisting of twelve 30-day months. The amount of interest
payable for any period shorter than a full quarterly period for which interest
is computed will be computed on the basis of the actual number of days elapsed
in the 90-day period. In the event that any date on which interest is payable
on the Senior Notes is not a business day, then payment of the interest payable
on such date will be made on the next succeeding day that is a business day,
without any interest or other payment in respect of the delay, except that, if
the business day is in the next succeeding calendar year, then the payment will
be made on the immediately preceding business day, in each case with the same
force and effect as if made on the scheduled payment date.

Market Rate Reset

   The reset rate will be equal to the sum of the reset spread and the rate of
interest on the applicable benchmark Treasury in effect on the applicable
remarketing date, and will be determined by the reset agent. In the case of a
reset on the third business day immediately preceding August 16, 2004,
September 16, 2004 or October 16, 2004, as the case may be, the reset rate will
be the rate determined by the reset agent as the rate the Senior Notes should
bear in order for the Senior Notes included in Duke Energy Corporate Units to
have an

                                      S-5



approximate aggregate market value on the reset date of 100.5% of the Treasury
portfolio purchase price. In the case of a reset on the third business day
immediately preceding November 16, 2004, the reset rate will be the rate
determined by the reset agent as the rate the Senior Notes should bear in order
for each Senior Note to have an approximate market value on the reset date of
100.5% of the principal amount of the Senior Note. The reset rate will in no
event exceed the maximum rate permitted by applicable law.

   The "applicable benchmark Treasury" means direct obligations of the United
States, as agreed upon by us and the reset agent (which may be obligations
traded on a when-issued basis only), having a maturity comparable to the
remaining term to maturity of the Senior Notes, which will be two years, two
and one-twelfth years, two and one-sixth years or two and one-quarter years, as
applicable. The rate for the applicable benchmark Treasury will be the bid side
rate displayed at 10:00 a.m., New York City time, on the third business day
immediately preceding August 16, 2004, September 16, 2004, October 16, 2004 or
November 16, 2004, as applicable, in the Telerate system (or if the Telerate
system is no longer available on that date or, in the opinion of the reset
agent (after consultation with us), is no longer an appropriate system from
which to obtain the rate, such other nationally recognized quotation system as,
in the opinion of the reset agent (after consultation with us), is
appropriate). If this rate is not so displayed, the rate for the applicable
benchmark Treasury will be, as calculated by the reset agent, the yield to
maturity for the applicable benchmark Treasury, expressed as a bond equivalent
on the basis of a year of 365 or 366 days, as applicable, and applied on a
daily basis, and computed by taking the arithmetic mean of the secondary market
bid rates, as of 10:30 a.m., New York City time, on the third business day
immediately preceding August 16, 2004, September 16, 2004, October 16, 2004 or
November 16, 2004, as applicable, of three leading United States government
securities dealers selected by the reset agent (after consultation with us)
(which may include the reset agent or an affiliate thereof). It is currently
anticipated that Morgan Stanley & Co. Incorporated will be the reset agent.

   On the tenth business day immediately preceding August 16, 2004, September
16, 2004, October 16, 2004 or November 16, 2004, the applicable benchmark
Treasury to be used to determine the reset rate on the third business day prior
to August 16, 2004, September 16, 2004, October 16, 2004, or November 16, 2004,
as applicable, will be selected, and the reset spread to be added to the rate
of interest on the applicable benchmark Treasury in effect on the third
business day immediately preceding August 16, 2004, September 16, 2004, October
16, 2004 or November 16, 2004, as applicable, will be established by the reset
agent, and the reset spread and the applicable benchmark Treasury will be
announced by us (the "reset announcement date"). We will cause a notice of the
reset spread and the applicable benchmark Treasury to be published on the
business day following the reset announcement date by publication in a daily
newspaper in the English language of general circulation in the City of New
York, which is expected to be The Wall Street Journal. We will also request,
not later than seven nor more than fifteen calendar days prior to the reset
announcement date, that the securities depositary for the Senior Notes notify
its participants holding Senior Notes (and Duke Energy will also so request
that the securities depositary for the Duke Energy Corporate Units and Duke
Energy Treasury Units notify its participants holding Duke Energy Corporate
Units or Duke Energy Treasury Units) of the reset announcement date and, in the
case of a final remarketing to be conducted on the third business day
immediately preceding November 16, 2004, if any, of the procedures that must be
followed if any owner of Duke Energy Corporate Units wishes to settle the
related purchase contract with separate cash on the fourth business day
immediately preceding November 16, 2004.

Optional Remarketing

   On or prior to the fifth business day immediately preceding August 16, 2004,
in the case of the remarketing to be conducted on the initial remarketing date,
or on or prior to the fifth business day immediately preceding the second,
third or fourth remarketing date in the case of the remarketing, if any, to be
conducted on the third business day preceding September 16, 2004, October 16,
2004 or November 16, 2004, respectively, but no earlier than the interest
payment date immediately preceding August 16, 2004, September 16, 2004, October
16, 2004 or November 16, 2004, as applicable, holders of Senior Notes that are
not part of Duke Energy Corporate Units may elect to have their Senior Notes
remarketed in the same manner as Senior Notes that are part of Duke

                                      S-6



Energy Corporate Units by delivering their Senior Notes along with a notice of
this election to the custodial agent designated by us. The custodial agent will
hold the Senior Notes in an account separate from the collateral account in
which the pledged Senior Notes are held. Holders of Senior Notes electing to
have their Senior Notes remarketed will also have the right to withdraw their
election on or prior to the fifth business day immediately preceding August 16,
2004, September 16, 2004, October 16, 2004 or November 16, 2004, as applicable.
The proceeds of the remarketing of Senior Notes that are not part of Duke
Energy Corporate Units will be paid to the holders in cash after deduction, to
the extent permissible, of the remarketing fee.

Tax Event Redemption

   If a tax event occurs and is continuing, we may, at our option, redeem the
Senior Notes in whole, but not in part, at any time at a redemption price equal
to, for each Senior Note, the redemption amount described below plus accrued
and unpaid interest, if any, to the redemption date. Installments of interest
on Senior Notes which are due and payable on or prior to a redemption date will
be payable to the holders of the Senior Notes registered as such at the close
of business on the relevant record dates. If, following the occurrence of a tax
event, we exercise our option to redeem the Senior Notes, the proceeds of the
redemption will be payable in cash to the holders of the Senior Notes except as
provided in the following sentence. If the tax event redemption occurs prior to
a successful remarketing of the Senior Notes, the redemption price for the
Senior Notes forming a part of the Duke Energy Corporate Units will be
distributed to the collateral agent, who in turn will purchase the Treasury
portfolio described below on behalf of the holders of Duke Energy Corporate
Units and remit the remainder of the redemption price, if any, to the purchase
contract agent designated by Duke Energy for payment to these holders. The
Treasury portfolio will be substituted for the Senior Notes and will be pledged
to the collateral agent for the benefit of Duke Energy to secure the Duke
Energy Corporate Unit holders' obligations to purchase Duke Energy common stock
under the purchase contracts that are part of the Duke Energy Corporate Units.

   "Tax event" means the receipt by us of an opinion of a nationally recognized
independent tax counsel experienced in such matters to the effect that there is
more than an insubstantial risk that interest payable by us on the Senior Notes
would not be deductible, in whole or in part, by us for United States federal
income tax purposes as a result of

   . any amendment to, change in, or announced proposed change in, the laws, or
     any regulations thereunder, of the United States or any political
     subdivision or taxing authority thereof or therein affecting taxation,

   . any amendment to or change in an interpretation or application of any such
     laws or regulations by any legislative body, court, governmental agency or
     regulatory authority, or

   . any interpretation or pronouncement that provides for a position with
     respect to any such laws or regulations that differs from the generally
     accepted position on the original issue date,

which amendment, change or proposed change is effective or which interpretation
or pronouncement is announced on or after the original issue date.

   The Treasury portfolio to be purchased on behalf of the holders of Duke
Energy Corporate Units will consist of

   . zero-coupon interest or principal strips of U.S. Treasury securities which
     mature on or prior to November 15, 2004 in an aggregate amount equal to
     the aggregate principal amount of the Senior Notes included in Duke Energy
     Corporate Units, and

   . with respect to each scheduled interest payment date on the Senior Notes
     that occurs after the tax event redemption date and on or before November
     16, 2004, zero-coupon interest or principal strips of U.S. Treasury
     securities which mature on or prior to that interest payment date in an
     aggregate amount equal to the aggregate interest payment that would be due
     on the aggregate principal amount of the Senior Notes on that date.

                                      S-7



   Solely for purposes of determining the Treasury portfolio purchase price in
the case of a tax event redemption date occurring on or after August 16, 2004,
September 16, 2004 or October 16, 2004 in the case of a successful remarketing
on any such date, or on or after November 16, 2004 if the third remarketing of
the Senior Notes on the third business day preceding October 16, 2004 resulted
in a failed remarketing, "Treasury portfolio" will mean a portfolio of
zero-coupon U.S. Treasury securities consisting of

   . principal or interest strips of U.S. Treasury securities which mature on
     or prior to November 15, 2006 in an aggregate amount equal to the
     aggregate principal amount of the Senior Notes outstanding on the tax
     event redemption date, and

   . with respect to each scheduled interest payment date on the Senior Notes
     that occurs after the tax event redemption date, interest or principal
     strips of U.S. Treasury securities which mature on or prior to that
     interest payment date in an aggregate amount equal to the aggregate
     interest payment that would be due on the aggregate principal amount of
     the Senior Notes outstanding on the tax event redemption date.

   "Redemption amount" means

   . in the case of a tax event redemption occurring prior to August 16, 2004,
     September 16, 2004 or October 16, 2004, or November 16, 2004 if the
     remarketing of the Senior Notes on the third business day preceding August
     16, 2004, September 16, 2004 or October 16, 2004, as the case may be,
     resulted in a failed remarketing, for each Senior Note the product of the
     principal amount of the Senior Note and a fraction whose numerator is the
     Treasury portfolio purchase price and whose denominator is the aggregate
     principal amount of Senior Notes included in Duke Energy Corporate Units,
     and

   . in the case of a tax event redemption date occurring on or after August
     16, 2004, September 16, 2004 or October 16, 2004 in the case of a
     successful remarketing on any such date, or November 16, 2004 if the third
     remarketing of the Senior Notes on the third business day preceding
     October 16, 2004 resulted in a failed remarketing, for each Senior Note
     the product of the principal amount of the Senior Note and a fraction
     whose numerator is the Treasury portfolio purchase price and whose
     denominator is the aggregate principal amount of the Senior Notes
     outstanding on the tax event redemption date.

   Depending on the amount of the Treasury portfolio purchase price, the
redemption amount could be less than or greater than the principal amount of
the Senior Notes.

   As used in this context, "Treasury portfolio purchase price" means the
lowest aggregate price quoted by a primary U.S. government securities dealer in
New York City to the quotation agent on the third business day immediately
preceding the tax event redemption date for the purchase of the Treasury
portfolio for settlement on the tax event redemption date.

   "Quotation agent" means Morgan Stanley & Co. Incorporated or its successor
or any other primary U.S. government securities dealer in New York City
selected by us.

   Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each registered holder of Senior Notes to
be redeemed at its registered address. Unless we default in payment of the
redemption price, on and after the redemption date interest will cease to
accrue on the Senior Notes. In the event any Senior Notes are called for
redemption, neither we nor the Senior Indenture Trustee will be required to
register the transfer of or exchange the Senior Notes to be redeemed.

Defeasance; Covenant Defeasance

   The provisions of the Senior Indenture that provide for defeasance and
covenant defeasance (as described in "Description of the Senior
Notes--Defeasance and Covenant Defeasance" in the accompanying prospectus) will
not apply to the Senior Notes.

                                      S-8



Book-Entry and Settlement

   Senior Notes which have been released from the pledge following substitution
thereof or early settlement of the purchase contracts that are part of the Duke
Corporate Units will be issued in the form of one or more global certificates,
which we refer to as global securities, registered in the name of the
securities depositary or its nominee. Except under the limited circumstances
described below or except upon recreation of Duke Energy Corporate Units from
Duke Energy Treasury Units, Senior Notes represented by the global securities
will not be exchangeable for, and will not otherwise be issuable as, Senior
Notes in certificated form. The global securities described above may not be
transferred except by the depositary to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or to a successor depositary or its nominee.

   The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of the securities in certificated form. These
laws may impair the ability to transfer beneficial interests in such a global
security.

   Except as provided below, owners of beneficial interests in such a global
security will not be entitled to receive physical delivery of Senior Notes in
certificated form and will not be considered the holders (as defined in the
Senior Indenture) thereof for any purpose under the Senior Indenture, and no
global security representing Senior Notes will be exchangeable, except for
another global security of like denomination and tenor to be registered in the
name of the depositary or its nominee or a successor depositary or its nominee.
Accordingly, each beneficial owner must rely on the procedures of the
securities depositary or, if such person is not a participant, on the
procedures of the participant through which such person owns its interest, to
exercise any rights of a holder under the Senior Indenture.

   In the event that

   . the depositary notifies us that it is unwilling or unable to continue as a

                                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

   The prospectus supplement for a particular series of Senior Notes being
offered will disclose the specific terms related to the offering, including the
price or prices at which the Senior 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 Senior Notes of the series;

                                      5



   . 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;

   . 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 Senior Notes and, if so,
     the terms of its redemption option;

   . any obligation that Duke Capital has to redeem the Senior Notes through a
     sinking fund or to purchase the Senior 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 Senior 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 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.

                                      26
