                               Notes due March 31, 2039.

                               preferred undivided beneficial interests in the
                               assets of the Trust.

Distributions; Distribution

                               to receive cumulative cash distributions at a
                               yearly rate of 7.20% of the liquidation amount
                               of $25 per Preferred Security. Distributions
                               will accrue from the original issue date.
                               Distributions will be payable, unless deferred,
                               quarterly on March 31, June 30, September 30 and
                               December 31 of each year, commencing on
                               September 30, 1999.

                               Subject to any deferral, distributions are
                               payable quarterly on the Preferred Securities.
                               The distribution dates will correspond to the
                               interest payment dates on the Series B

                                      S-3
<PAGE>

                               Junior Subordinated Notes and the rate at which
                               distributions will be paid on the Preferred
                               Securities will correspond to the interest rate
                               on the Series B Junior Subordinated Notes. If
                               Duke Energy does not pay principal or interest
                               on the Series B Junior Subordinated Notes, no
                               amounts will be paid on the Preferred
                               Securities.

Record Dates................  The close of business on the 15th calendar day
                               before the relevant distribution date.

Series B Junior
Subordinated Notes..........  $257,731,975 of Duke Energy's Series B Junior
                               Subordinated Notes due March 31, 2039. Duke
                               Energy will issue the Series B Junior
                               Subordinated Notes under its Subordinated
                               Indenture. The Trust will use the proceeds from
                               the sale of the Preferred Securities to purchase
                               Series B Junior Subordinated Notes. The Series B
                               Junior Subordinated Notes will be unsecured
                               subordinated obligations of Duke Energy.

Deferral of Distributions...  Duke Energy has the right to defer payments of
                               interest on the Series B Junior Subordinated
                               Notes by extending the interest payment period
                               on the Series B Junior Subordinated Notes, at
                               any time and as often as it wishes, for up to 20
                               consecutive quarters (each, an "extension
                               period") but not beyond the maturity date of the
                               Series B Junior Subordinated Notes. If Duke
                               Energy defers payments of interest on the Series
                               B Junior Subordinated Notes, distributions on
                               the Preferred Securities will also be deferred.

                               Deferred interest will bear interest at a yearly
                               rate of 7.20%, compounded quarterly, to the date
                               of payment, to the extent legally permitted.
                               Payments of deferred interest, and any interest
                               on deferred interest, on the Series B Junior
                               Subordinated Notes will be passed through to the
                               holders of the Preferred Securities.

                               The only restrictions on Duke Energy's ability
                               to defer payments of interest are that during
                               the extension period Duke Energy may not, with
                               certain exceptions, (1) pay dividends on, or
                               redeem or otherwise purchase, any of its capital
                               stock or (2) pay principal or interest on, or
                               redeem or otherwise purchase, any debt
                               securities ranking equal in

                                      S-4
<PAGE>

                               priority with or subordinate to the Series B
                               Junior Subordinated Notes.

                               During an extension period, holders of Preferred
                               Securities will recognize interest income for
                               United States federal income tax purposes in
                               advance of the receipt of the cash payments of
                               those deferred distributions even if the holder
                               is a cash basis taxpayer.

Redemption..................  The Trust will redeem the Preferred Securities
                               when Duke Energy repays the Series B Junior
                               Subordinated Notes at maturity or upon
                               redemption.

                               Duke Energy may redeem the Series B Junior
                               Subordinated Notes at any time, in whole or in
                               part, on or after June 30, 2004. Duke Energy may
                               also redeem the Series B Junior Subordinated
                               Notes at any time, in whole but not in part,
                               during the 90 days after the occurrence of a
                               Special Event (see below).

Redemption Price............  If the Preferred Securities are redeemed or the
                               Trust is terminated without distribution of the
                               Series B Junior Subordinated Notes, each holder
                               of a Preferred Security will be entitled to
                               receive a liquidation amount of $25 per
                               Preferred Security plus accrued and unpaid
                               distributions (including any interest on those
                               distributions) to the date of payment.

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

                               A "Tax Event" means that because of changes in
                               certain tax laws or regulations or in how they
                               are interpreted or applied, there is more than
                               an insubstantial risk that (1) the Trust would
                               be subject to United States federal income tax
                               with respect to income accrued or received on
                               the Series B Junior Subordinated Notes, (2)
                               interest payable on the Series B Junior
                               Subordinated Notes would not be deductible by
                               Duke Energy for United States federal income tax
                               purposes or (3) the Trust would be subject to
                               more than a de minimis amount of other taxes,
                               duties or other governmental charges.

                               An "Investment Company Act Event" means that
                               because of changes in certain laws or
                               regulations or in how they are interpreted or
                               applied, there is more than an

                                      S-5
<PAGE>

                               insubstantial risk that the Trust is or will be
                               considered an "investment company" under the
                               Investment Company Act of 1940.

Termination of Trust........  Duke Energy will have the right to terminate the
                               Trust at any time and cause the Property Trustee
                               to distribute Series B Junior Subordinated Notes
                               to the holders of the Preferred Securities in
                               exchange for those Preferred Securities. This
                               right is optional and wholly in Duke Energy's
                               discretion.

Ranking of Series B
Junior Subordinated Notes...  The Series B Junior Subordinated Notes will be
                               subordinate and junior in right of payment to
                               all indebtedness for borrowed money and other
                               obligations of Duke Energy included in the
                               definition of Senior Indebtedness. See

                               Subordination" in the accompanying Prospectus
                               for a description of Senior Indebtedness.

Guarantee...................  Duke Energy will guarantee the payment of
                               distributions and other payments by the Trust on
                               the Preferred Securities, but only to the extent
                               that the Trust has funds legally and immediately
                               available to make those distributions and
                               payments.

Ranking of Guarantee........  Duke Energy's obligations under the Guarantee
                               will be subordinate and junior in right of
                               payment to all of Duke Energy's other
                               liabilities, other than similar guarantees. The
                               Guarantee will rank equal in priority with Duke
                               Energy's preferred stock and preferred stock A
                               and with similar guarantees.

Book-Entry Issuance.........  The Preferred Securities will be represented by a
                               global certificate or certificates deposited
                               with and registered in the name of The
                               Depository Trust Company, New York, New York or
                               its nominee. This means that investors will not
                               receive certificates for their Preferred
                               Securities.

Listing.....................  The Preferred Securities have been approved for
                               listing on the New York Stock Exchange, subject
                               to official notice of issuance, under the symbol
                               "DUK PrV." Duke Energy expects that trading in
                               the Preferred Securities on the New York Stock
                               Exchange will begin within 30 days after the
                               original issue date.

The Trustees................  The Chase Manhattan Bank will act as Property
                               Trustee of the Trust. Two of Duke Energy's
                               officers will act as the Administrative Trustees
                               of the Trust. Chase Manhattan Bank Delaware will
                               be the Delaware Trustee of the Trust. The Chase
                               Manhattan Bank also serves as the Indenture
                               Trustee--the trustee under Duke Energy's
                               Subordinated Indenture under which the Series B
                               Junior Subordinated Notes will be issued--and
                               will act as the Guarantee Trustee--the trustee
                               under the Guarantee. The Chase Manhattan Bank is
                               also the Trustee under Duke Energy's First and
                               Refunding Mortgage and its Senior Indenture. The
                               Property Trustee, Delaware Trustee and
                               Administrative Trustees together are sometimes
                               referred to as the "Securities Trustees" in this
                               Prospectus Supplement.

                                  RISK FACTORS

  An investment in the Preferred Securities involves a number of risks. Some
risks relate to the nature of the Preferred Securities. Other risks relate to
Duke Energy. You should carefully read and consider the following risk factors,
as well as the other information contained in this Prospectus Supplement and
the accompanying Prospectus, before you buy any Preferred Securities.

Payments on the Preferred Securities Depend upon Payments on the Series B
Junior Subordinated Notes

  The only source of funds for payments on the Preferred Securities will be the
payments that Duke Energy makes on the Series B Junior Subordinated Notes. If
Duke Energy fails to make timely payments on the Series B Junior Subordinated
Notes, the Trust will lack available funds for distributions or other payments
on the Preferred Securities.

Rights under the Guarantee

  If the Trust does not have sufficient funds legally and immediately
available, the holders of the Preferred Securities will not be able to rely
upon the Guarantee for distributions or other payments on the Preferred
Securities.

Ranking of the Guarantee

  Duke Energy's obligations under the Guarantee 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.

Ranking of the Series B Junior Subordinated Notes

  Duke Energy's obligations under the Series B Junior Subordinated Notes are
subordinate and junior in right of payment to all of Duke Energy's Senior
Indebtedness. For a description of Duke Energy's Senior Indebtedness, see
"Description of the Junior Subordinated Notes--Subordination" in the
accompanying Prospectus.

  The Preferred Securities, the Series B Junior Subordinated Notes and the
Guarantee do not limit Duke Energy's ability to incur additional Senior
Indebtedness or other indebtedness.

  Duke Energy conducts its non-electric operations, and certain of its electric
operations outside its service area in the Carolinas, through subsidiaries.
Accordingly, Duke Energy's ability to meet its obligations under the Series B
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 will 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. Duke Energy anticipates that
certain of its subsidiaries will incur substantial amounts of debt in the
expansion of their businesses.


                                      S-8
<PAGE>

Option to Extend Interest Payment Period

  Duke Energy will have the right, at any time and from time to time, to defer
interest payments on the Series B Junior Subordinated Notes for up to 20
consecutive quarters, but not beyond the maturity date of the Series B Junior
Subordinated Notes. Any such deferral period is called an "extension period" in
this Prospectus Supplement. During an extension period distributions on the
Preferred Securities will also be deferred.

  Duke Energy will pay interest on any deferred interest on the Series B Junior
Subordinated Notes at a yearly rate of 7.20%, compounded quarterly, to the date
of payment, to the extent legally permitted. Payments of deferred interest,
together with any interest on those payments, will be passed through to the
holders of the Preferred Securities.

  If Duke Energy defers interest payments, each holder of Preferred Securities,
or of Series B Junior Subordinated Notes, will recognize income as original
issue discount for federal income tax purposes before the holder is paid
deferred distributions of interest. This will be so even if the holder is a
cash basis taxpayer. A holder of Preferred Securities, or of Series B Junior
Subordinated Notes, will not receive cash related to that income if the holder
disposes of the Preferred Securities, or the Series B Junior Subordinated
Notes, before the record date for the payment of such amounts. Investors should
consult their own tax advisors with respect to these and other tax consequences
of an investment in the Preferred Securities.

Special Event Redemption

  Duke Energy will have the option to redeem the Series B Junior Subordinated
Notes in whole during the 90 days after the occurrence of a Special Event. If
Duke Energy redeems the Series B Junior Subordinated Notes after the occurrence
of a Special Event, the Trust will redeem the Preferred Securities.

Distribution of Series B Junior Subordinated Notes upon Termination of Trust

  Duke Energy will have the right to terminate the Trust at any time and cause
the Series B Junior Subordinated Notes to be distributed to the holders of the
Preferred Securities in liquidation of the Trust.

  There can be no assurance as to the market price for the Series B Junior
Subordinated Notes if a termination and liquidation of the Trust occurs and
Series B Junior Subordinated Notes are distributed in exchange for Preferred
Securities. The Series B Junior Subordinated Notes that the investor would
receive may trade at less than the price that the investor paid to purchase the
Preferred Securities.

Limited Voting Rights

  Holders of Preferred Securities will have limited voting rights. See
"Description of the Preferred Securities--Voting Rights" for additional
information.

                                      S-9
<PAGE>

  In general, holders of Preferred Securities will not be entitled to vote to
appoint, remove or replace any of the Securities Trustees. Duke Energy, as the
holder of the Common Securities, generally has that right. However, the holders
of the Preferred Securities will have the right to appoint a substitute
Property Trustee or Delaware Trustee if an event of default with respect to the
Series B Junior Subordinated Notes occurs and is continuing.

Trading Characteristics of Preferred Securities

  Duke Energy expects to list the Preferred Securities on the New York Stock
Exchange. The Preferred Securities are expected to trade at a price that takes
into account the value, if any, of accrued but unpaid distributions.
Accordingly, purchasers will not pay and sellers will not receive accrued and
unpaid interest with respect to Preferred Securities that is not included in
the trading price of the Preferred Securities.

  If a holder disposes of Preferred Securities prior to the occurrence of an
extension period, any portion of the amount received that is attributable to
accrued interest will be treated as interest income for tax purposes and will
not be treated as part of the amount realized for purposes of determining gain
or loss on the disposition of the Preferred Securities. If an extension period
occurs, interest on the Series B Junior Subordinated Notes will be included in
the income of holders of Preferred Securities as it accrues rather than when it
is paid. If an extension period occurs, a holder that disposes of its Preferred
Securities between record dates for payments of distributions will be required
to include in income as original issue discount accrued but unpaid interest on
the Series B Junior Subordinated Notes through the date of disposition and to
add that amount to the holder's adjusted tax basis in the related Series B
Junior Subordinated Notes deemed disposed of. A holder generally will recognize
a capital loss to the extent the selling price is less than the holder's
adjusted tax basis. Subject to certain limited exceptions, capital losses
cannot be applied to offset ordinary income for federal income tax purposes.

  No public market for the Preferred Securities existed before this offering.
There can be no assurance that an active public market for the Preferred
Securities will develop. If an active trading market for the Preferred
Securities does develop, there can be no assurance that it will be sustained
after this offering.

Investment in Trust Involves Risks Parallel to Those of Investment in Duke
Energy

  An investment in the Trust, like an investment in Duke Energy, will involve
risks associated with Duke Energy's operating conditions and will be affected
by the competitive factors, economic conditions, industry conditions and equity
market conditions to which Duke Energy is subject.

Consequences of Highly Leveraged Transaction

  The Subordinated Indenture does not contain provisions that will protect
holders of the Series B Junior Subordinated Notes if Duke Energy engages in a
highly leveraged transaction. The Trust Agreement does not contain provisions
that will protect holders of Preferred Securities under those circumstances.

                          DUKE ENERGY CAPITAL TRUST II

  Duke Energy created the Trust as a statutory business trust under Delaware
law. The Trust's business is defined in a trust agreement executed by Duke
Energy, as depositor, and the Delaware Trustee. That trust agreement will be
amended when the Preferred Securities are issued. The amended trust agreement
will be in substantially the form filed as an exhibit to the Registration
Statement of which this Prospectus Supplement and the accompanying Prospectus
are a part. The amended trust agreement is called the "Trust Agreement" in this
Prospectus Supplement.

  The Trust exists for the exclusive purposes of issuing and selling the
Preferred Securities to the public and the Common Securities to Duke Energy and
investing the gross proceeds in the Series B Junior Subordinated Notes. The
Trust may engage in only those other activities as are necessary, appropriate,
convenient or incidental to those purposes. The Preferred Securities and the
Common Securities together are sometimes called the "Trust Securities" in this
Prospectus Supplement.

  The Trust has a term of approximately 45 years from its creation, but may
terminate earlier as provided in the Trust Agreement.

  The Securities Trustees will conduct the Trust's business and affairs. Duke
Energy, as the holder of the Common Securities, will appoint the Securities
Trustees. Two of Duke Energy's officers initially will serve as Administrative
Trustees. The Chase Manhattan Bank will serve as Property Trustee. Chase
Manhattan Bank Delaware will serve as Delaware Trustee. Duke Energy, as the
holder of all the Common Securities, will have the right to appoint, remove or
replace any of the Securities Trustees, subject to the right of the holders of
a majority of the Preferred Securities to appoint a substitute Property Trustee
and Delaware Trustee if an event of default with respect to the Series B Junior
Subordinated Notes occurs.

  The Property Trustee will hold legal title to the Series B Junior
Subordinated Notes for the benefit of the Trust and the holders of the Trust
Securities. The Property Trustee will have the power, with certain exceptions,
to exercise all rights, powers and privileges under the Subordinated Indenture
as the holder of the Series B Junior Subordinated Notes.

  The Series B Junior Subordinated Notes will constitute substantially all the
assets of the Trust. Other assets that may constitute "Trust Property" include
any cash on deposit in, or owing to, the payment account established under the
Trust Agreement. Trust Property will also include any other property or assets
that the Property Trustee holds under the Trust Agreement. The Trust may from
time to time receive cash from Duke Energy under the Agreement as to Expenses
and Liabilities between Duke Energy and the Trust.

  The Trust's office address in the State of Delaware is c/o Chase Manhattan
Bank Delaware, 1201 Market Street, Wilmington, Delaware 19801. The principal
place of business of the Trust will be c/o Duke Energy Corporation, 526 South
Church Street, Charlotte, North Carolina 28202 (telephone (704) 594-6200).

                    DESCRIPTION OF THE PREFERRED SECURITIES

  The following description of the Preferred Securities is only a summary and
is not intended to be comprehensive. For additional information you should
refer to the Trust Agreement. The form of the Trust Agreement is an exhibit to
the Registration Statement of which this Prospectus Supplement and the
accompanying Prospectus are a part.

General

  The Trust Agreement authorizes the Administrative Trustees to issue the
Preferred Securities and the Common Securities on behalf of the Trust. The
Preferred Securities represent preferred undivided beneficial interests in the
assets of the Trust. The Common Securities represent common undivided
beneficial interests in the assets of the Trust. The Trust Agreement does not
permit the Trust to issue any other securities or to incur any indebtedness for
borrowed money.

  The Preferred Securities will have an aggregate liquidation amount equal to
approximately 97% of the total capital of the Trust. The Common Securities will
have an aggregate liquidation amount equal to approximately 3% of the total
capital of the Trust.

  Duke Energy will own all the Common Securities.

  In general, the Preferred Securities will rank equal in priority with the
Common Securities and the Trust will make payments on the Preferred Securities
on a pro rata basis with the Common Securities. The rights of the holders of
the Preferred Securities to receive distributions and liquidation, redemption
and other payments will be senior to the rights of the holder of the Common
Securities if an event of default occurs under the Subordinated Indenture with
respect to the Series B Junior Subordinated Notes.

  Duke Energy has guaranteed, on a subordinated basis, certain payments with
respect to the Preferred Securities. Those payments are payments of
distributions and payments if the Preferred Securities are redeemed or the
Trust is liquidated, in each case to the extent set forth in the Guarantee. The
Guarantee does not cover those payments when the Trust does not have sufficient
funds legally and immediately available to make the payments. In that event,
the holders of a majority of the Preferred Securities may direct the Property
Trustee to enforce its rights under the Series B Junior Subordinated Notes. In
addition, a holder of Preferred Securities may institute a legal proceeding
directly against Duke Energy, without first instituting a legal proceeding
against the Property Trustee or any other person or entity, to enforce payment
to that holder of principal or interest on Series B Junior Subordinated Notes
having a principal amount equal to the liquidation amount of that holder's
Preferred Securities on or after the due dates specified or provided for in the
Series B Junior Subordinated Notes. These mechanisms and obligations, together
with Duke Energy's obligations under the Agreement as to Expenses and
Liabilities, provide a full and unconditional guarantee by Duke Energy of the
payments due on the Preferred Securities, subject to certain subordination
provisions.

                                      S-12
<PAGE>

Distributions

  Distributions on the Preferred Securities will be fixed at a yearly rate of
7.20% and will accrue from the original issue date of the Preferred Securities.

  Distributions on the Preferred Securities will be payable quarterly in
arrears on the following distribution dates: March 31, June 30, September 30
and December 31 of each year, commencing on September 30, 1999, except if an
extension period occurs. Distributions payable on a date that is not a Business
Day will be paid on the next day that is a Business Day (without any interest
or other payment due to the delay), except that if that Business Day falls in
the next calendar year, the payment will be made on the immediately preceding
Business Day. In each such case, payment will be made with the same effect as
if made on the date the payment was originally payable. "Business Day" means
any day other than a Saturday or Sunday, a day on which banks in New York City
are authorized or obligated by law or executive order to remain closed or a day
on which the principal corporate trust office of the Property Trustee or the
Indenture Trustee is closed for business.

  Distributions on the Preferred Securities will be payable to holders of
record at the close of business on the 15th calendar day before the relevant
distribution date. Each payment of a distribution will be made as described
under the caption "--Book-Entry Issuance--The Depository Trust Company" in this
Prospectus Supplement while the Preferred Securities are in book-entry only
form. Distributions will be computed on the basis of a 360-day year of twelve
30-day months.

  Duke Energy has the right to defer interest payments on the Series B Junior
Subordinated Notes by extending the interest payment period from time to time
on the Series B Junior Subordinated Notes. If Duke Energy exercises that right,
distributions on the Preferred Securities will be deferred during the extension
period. Deferred interest installments on the Series B Junior Subordinated
Notes will bear interest at a yearly rate of 7.20%, compounded quarterly, to
the payment date, to the extent legally permitted. Duke Energy will have the
right to make partial payments of interest on any interest payment date during
an extension period. If distributions are deferred, the deferred distributions
and accrued interest on those distributions will be paid, if funds are legally
available for those payments, to holders of record of the Preferred Securities
on the record date immediately after the extension period ends.

  The Trust will pay distributions on the Preferred Securities on the
distribution dates to the extent that it has funds legally and immediately
available. Those funds will be limited to payments that Duke Energy makes under
the Series B Junior Subordinated Notes.

Redemption

  The Trust will redeem the Preferred Securities when Duke Energy repays the
Series B Junior Subordinated Notes at maturity or upon redemption. The Series B
Junior Subordinated Notes will mature on March 31, 2039. Duke Energy may redeem
the Series B Junior Subordinated Notes, in whole or in part, at its option at
any time on or after June 30, 2004. Duke Energy may also redeem the Series B
Junior Subordinated Notes, in whole but not in part, at any time during the 90
days after the occurrence of a Special Event. In each case the redemption price
will be equal to 100% of the principal amount of the Series B Junior
Subordinated Notes to be redeemed plus accrued but unpaid interest (including
any Additional Interest as defined below) to the redemption date. Duke Energy
may redeem the Series B Junior Subordinated Notes only in whole if a partial
redemption of the Series B Junior Subordinated Notes would cause the Preferred
Securities to be delisted.

                                      S-13
<PAGE>

  Any Preferred Securities that are to be redeemed will be redeemed upon at
least 30 but not more than 60 days' notice at a redemption price for each
Preferred Security equal to the liquidation amount of $25 plus any accrued and
unpaid distributions on the Preferred Security to the date of payment. Any
Preferred Securities that are to be redeemed will be redeemed with the proceeds
from the redemption of an equivalent amount of Series B Junior Subordinated
Notes. The redemption price of the Preferred Securities will be deemed payable
on each redemption date only to the extent that the Trust has funds legally and
immediately available for payment of that redemption price.

  If fewer than all the outstanding Preferred Securities are to be redeemed and
the Preferred Securities are in book-entry form, DTC will reduce the amount of
the interest of each of its participants in the Preferred Securities in
accordance with its procedures. If the Preferred Securities are no longer in
book-entry form, the Property Trustee will redeem the Preferred Securities to
be redeemed in any manner that it deems fair and appropriate.

Special Event Redemption or Distribution

  Duke Energy may at its option redeem all the Series B Junior Subordinated
Notes during the 90 days after the occurrence of a Special Event. In that
event, the Preferred Securities will also be redeemed.

  A Special Event is either a Tax Event or an Investment Company Act Event.

  A "Tax Event" means that the Administrative Trustees and Duke Energy have
received an opinion of counsel experienced in such matters to the effect that,
as a result of:

  . any amendment to, or change (including any announced prospective change)
    in, the laws (or any regulations under those laws) of the United States
    or any political subdivision or taxing authority of or in the United
    States; or

  . any amendment to, or change in, an interpretation or application of such
    laws or regulations,

there is more than an insubstantial risk that:

  . the Trust would be subject to United States federal income tax with
    respect to income accrued or received on the Series B Junior Subordinated
    Notes;

  . interest payable on the Series B Junior Subordinated Notes would not be
    deductible by Duke Energy for United States federal income tax purposes;
    or

  . the Trust would be subject to more than a de minimis amount of other
    taxes, duties or other governmental charges,

which amendment or change becomes effective on or after the original issue date
of the Preferred Securities.

  An "Investment Company Act Event" means that the Administrative Trustees and
Duke Energy have received an opinion of counsel experienced in such matters to
the effect that, as a result of the occurrence of a change in law or regulation
or a written change in interpretation or application of law or regulation by
any legislative body, court, governmental agency or regulatory authority on or
after the original issue date of the Preferred Securities, there is more than
an insubstantial risk that the Trust is or will be considered an "investment
company" under the Investment Company Act of 1940, which change becomes
effective on or after the original issue date of the Preferred Securities.

                                      S-14

Distribution of Series B Junior Subordinated Notes upon Termination of Trust

  Duke Energy will have the right to terminate the Trust at any time and, after
the Trust satisfies its liabilities to creditors, cause the Series B Junior
Subordinated Notes to be distributed to the holders of the Preferred Securities
in liquidation of the Trust. That right is optional and wholly within Duke
Energy's discretion.

  Circumstances under which Duke Energy may decide to exercise its right to
terminate the Trust could include:

  . the occurrence of an Investment Company Act Event or a Tax Event;

  . adverse tax consequences to Duke Energy or the Trust that the definition
    of a Tax Event does not cover because those consequences do not result
    from an amendment or change described in that definition; and

  . changes in the accounting requirements applicable to the Preferred
    Securities that are described under the caption "Accounting Treatment" in
    the accompanying Prospectus.

  If Series B Junior Subordinated Notes are distributed to the holders of the
Preferred Securities, Duke Energy will use its best efforts to have the Series
B Junior Subordinated Notes listed on the New York Stock Exchange or other
exchange on which the Preferred Securities are then listed.

  After the date for any distribution of Series B Junior Subordinated Notes
upon termination of the Trust:

  . the Preferred Securities and the Guarantee will no longer be considered
    outstanding;

  . the securities depositary or its nominee, as the record holder of the
    Preferred Securities, will receive a registered global certificate or
    certificates representing the Series B Junior Subordinated Notes
    delivered upon the distribution; and

  . any certificates representing Preferred Securities not held by the
    securities depositary or its nominee will be deemed to represent Series B
    Junior Subordinated Notes. Those Series B Junior Subordinated Notes will
    have:

   . an aggregate principal amount equal to the aggregate liquidation amount
     of those Preferred Securities;

   . an interest rate identical to the rate at which cumulative cash
     distributions are payable on those Preferred Securities; and

   . accrued and unpaid interest equal to the accrued and unpaid
     distributions on those Preferred Securities,

  until the certificates are presented to Duke Energy or its agent for transfer
or reissuance.

  There can be no assurance as to the market prices for either the Preferred
Securities or the Series B Junior Subordinated Notes that may be distributed in
exchange for the Preferred Securities if a termination and liquidation of the
Trust occurs. Accordingly, the Preferred Securities that an investor may
purchase, or the Series B Junior Subordinated Notes that the investor may
receive if the Trust is terminated or liquidated, may trade at a price less
than the price paid by the investor to purchase the Preferred Securities.

Redemption Procedures

  If the Trust has the funds required for the redemption and the Preferred
Securities are in book-entry form, then the Property Trustee will irrevocably
deposit sufficient funds with the securities depositary on the redemption date
to pay the redemption price. If the Trust has the funds required for the
redemption and the Preferred Securities are not in book-entry form, the
Property Trustee will irrevocably deposit sufficient funds with the paying
agent to pay the redemption price and will instruct the paying agent to pay the
redemption price to the holders of the Preferred Securities upon surrender of
their Preferred Securities certificates. Immediately before the close of
business on the deposit date, distributions will cease to accrue and all rights
of holders of Preferred Securities called for redemption will cease, except the
right of those holders to receive the redemption price, without interest on it.

  If the redemption date is not a Business Day, the redemption price payable on
that date will be paid on the next day that is a Business Day (without any
interest or other payment due to the delay), except that if that Business Day
falls in the next calendar year, the payment will be made on the immediately
preceding Business Day.

  If fewer than all the Trust Securities are to be redeemed, the liquidation
amount of the Trust Securities to be redeemed will be allocated 97% to the
Preferred Securities and 3% to the Common Securities.

  If the Trust does not pay the redemption price and Duke Energy does not pay
the redemption price under the Guarantee, distributions on the Preferred
Securities to be redeemed will continue to accrue at the applicable rate from
the redemption date originally established for those Preferred Securities to
the date the redemption price is actually paid.

  The Preferred Securities will be book-entry securities. Upon issuance, all
book-entry securities will be represented by one or more fully registered
global certificates. Each global certificate will be deposited with, or on
behalf of, The Depository Trust Company ("DTC"), a securities depositary, and
will be registered in the name of DTC or a nominee of DTC. DTC or its nominee
will thus be the only registered holder of those Preferred Securities and will
be considered the sole owner of the Preferred Securities for purposes of the
Trust Agreement.

  Purchasers of Preferred Securities may only hold interests in the global
securities through DTC if they are participants in the DTC system. Purchasers
may also hold interests through a securities intermediary--banks, brokerage
houses and other institutions that maintain securities accounts for customers--
that has an account with DTC. DTC will maintain accounts showing the Preferred
Security holdings of its participants, and those participants will in turn
maintain accounts showing the Preferred Security holdings of their customers.
Some of those customers may themselves be

                                      S-16
<PAGE>

securities intermediaries holding Preferred Securities for their customers.
Thus, each beneficial owner of a book-entry Preferred Security will hold that
Preferred Security indirectly through a hierarchy of intermediaries, with DTC
at the "top" and the beneficial owner's own securities intermediary at the
"bottom."

  The Preferred Securities of each beneficial owner of a book-entry security
will be evidenced solely by entries on the books of the beneficial owner's
securities intermediary. The actual purchaser of the Preferred Securities will
generally not be entitled to have the Preferred Securities represented by the
global securities registered in its name and will not be considered the owner
under the Trust Agreement. In most cases, a beneficial owner will also not be
able to obtain a paper certificate evidencing the holder's ownership of
Preferred Securities. The book-entry system for holding Preferred Securities
eliminates the need for physical movement of certificates and is the system
through which most publicly traded common stock is held in the United States.
However, the laws of some jurisdictions require some purchasers of securities
to take physical delivery of their securities in definitive form. These laws
may impair the ability to transfer book-entry securities.

  A beneficial owner of book-entry Preferred Securities represented by a global
security will receive definitive (paper) Preferred Securities only if:

  . DTC is unwilling or unable to continue as depositary for such global
    security and Duke Energy is unable to find a qualified replacement for
    DTC within 90 days; or

  . Duke Energy in its sole discretion decides to terminate the book-entry
    system with respect to the Preferred Securities.

  Definitive Preferred Securities in registered form will have the same terms
and be in an equal aggregate principal amount as the equivalent book-entry
Preferred Securities, and will be in denominations of $25 or whole multiples of
$25. Definitive Preferred Securities will be registered in the name or names of
the person or persons that DTC specifies in a written instruction to the
registrar of the securities. DTC may base its written instruction upon
directions it receives from its participants.

  In this Prospectus Supplement, for book-entry Preferred Securities,
references to actions taken by holders of Preferred Securities will mean
actions taken by DTC upon instructions from its participants, and references to
payments and notices of redemption to holders of Preferred Securities will mean
payments and notices of redemption to DTC or its nominee as the registered
holder of the Preferred Securities for distribution to participants in
accordance with DTC's procedures.

  DTC is a limited purpose trust company organized under the laws of the State
of New York, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code and a "clearing
agency" registered under section 17A of the Securities Exchange Act of 1934.
The rules applicable to DTC and its participants are on file with the SEC.

  DTC's management is aware that some computer applications, systems and the
like for processing dates that are dependent upon calendar dates, including
dates before, on, and after January 1, 2000, may encounter "Year 2000
problems." DTC has informed its participants and other members of the financial
community that it has developed and is implementing a program so that its

                                      S-17
<PAGE>

systems, as they relate to the timely payment of distributions to
securityholders, book-entry deliveries and settlement of trades within DTC,
continue to function appropriately. This program includes a technical
assessment and a remediation plan, each of which is complete. Additionally,
DTC's plan includes a testing phase, which is expected to be completed within
appropriate time frames.

  Duke Energy, the Trust and the Securities Trustees will not have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests in the book-entry
securities or for maintaining, supervising or reviewing any records relating to
the beneficial ownership interests.

  The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that Duke Energy and the Trust believe to be
reliable, but neither Duke Energy nor the Trust takes responsibility for its
accuracy. Duke Energy and the Trust have no responsibility for the performance
by DTC, its participants or any securities intermediaries of their obligations,
including obligations that they have under the rules and procedures that govern
their operations.

Liquidation Distribution upon Dissolution

  The Trust will terminate on March 31, 2043, or earlier:

  . if one of certain bankruptcy, insolvency or reorganization events occurs
    with respect to Duke Energy, Duke Energy is dissolved or liquidated, or
    the Trust is dissolved by judicial decree;

  . if Duke Energy directs the Property Trustee to terminate the Trust and to
    distribute the Series B Junior Subordinated Notes to the holders of the
    Trust Securities in liquidation of the Trust; or

  . if Duke Energy repays all the Series B Junior Subordinated Notes at
    maturity or redemption and the Trust Securities are paid in full as a
    result.

  If an early termination occurs as described in the first and second instances
listed above, the Trust will be liquidated and the Property Trustee will
distribute an equivalent amount of Series B Junior Subordinated Notes to each
holder of Trust Securities after the Trust satisfies its liabilities to
creditors. If the Administrative Trustees determine that the distribution of
Series B Junior Subordinated Notes is not practical in the case of the first
instance listed above, those holders instead will receive an amount equal to
the liquidation amount of $25 per Trust Security plus accrued and unpaid
distributions to the date of payment out of the assets of the Trust that are
available for distribution, after satisfaction of the Trust's liabilities to
creditors. That amount is called the "liquidation distribution" in this
Prospectus Supplement.

  If the Trust does not have sufficient assets available to pay the total
liquidation distribution of the Trust Securities, then, except as described in
the next sentence, the Trust will make the payment to the holders of the
Preferred Securities and the holder of the Common Securities on a pro rata
basis. If an event of default under the Subordinated Indenture has occurred and
is continuing with respect to the Series B Junior Subordinated Notes, however,
the Preferred Securities will have a preference over the Common Securities with
respect to the payment.


                                      S-18

Events of Default

  The following are events of default under the Trust Agreement:

  . the occurrence of an event of default under the Subordinated Indenture
    with respect to the Series B Junior Subordinated Notes;

  . the Trust's failure to pay any distribution, when due, that continues for
    30 days;

  . the Trust's failure to pay the redemption price of any Preferred Security
    or Common Security when due;

  . failure to perform, or breach of, any covenant or warranty of the
    Securities Trustees in the Trust Agreement that continues for 60 days
    after the holders of at least 25% of the outstanding Preferred Securities
    give written notice of the failure or breach, requiring it to be
    remedied; or

  . the occurrence of certain bankruptcy or insolvency events with respect to
    the Trust.

In the case of the fourth event of default listed above, the holders of at
least the same percentage of Preferred Securities as had given the default
notice may extend the grace period. The grace period will be automatically
extended if the Securities Trustees have initiated and are diligently pursuing
corrective action.

  The Property Trustee will notify the holders of Trust Securities, the
Administrative Trustees and Duke Energy of any default known to it within 90
days after the default occurs, unless the default has been cured or waived. For
this purpose, the term "default" means any event which is an event of default
or which would become an event of default after notice has been given or a
grace period has expired or both, as the case may be.

  If an event of default under the Subordinated Indenture with respect to the
Series B Junior Subordinated Notes occurs and is continuing:

  . the holders of Preferred Securities will rely on the Property Trustee, as
    the holder of the Series B Junior Subordinated Notes, to enforce its
    rights against Duke Energy; and

  . the holders of a majority of the Preferred Securities will have the right
    to direct the time, method and place of conducting any proceeding for any
    remedy available to the Property Trustee or the exercise of any power of
    the Property Trustee under the Trust Agreement, including the right to
    direct the Property Trustee to exercise the remedies available to it as
    the holder of the Series B Junior Subordinated Notes.

  If the Property Trustee fails to enforce its rights under the Series B Junior
Subordinated Notes, a holder of Preferred Securities may, to the extent
permitted by law and the Trust Agreement, institute a legal proceeding against
Duke Energy to enforce the Property Trustee's rights under the Trust Agreement.
The holder would not need to first institute a legal proceeding against the
Property Trustee, the Trust or any other person or entity. A holder of
Preferred Securities may also institute a legal proceeding directly against
Duke Energy to enforce payment to that holder of principal or interest on
Series B Junior Subordinated Notes that are equal in principal amount to the
liquidation amount of the holder's Preferred Securities on or after the due
dates of the Series B Junior Subordinated Notes. The holder would not need to
first institute a legal proceeding against the Property Trustee or any other
person or entity.

                                      S-19
<PAGE>

  Duke Energy, as the holder of the Common Securities, may remove the
Securities Trustees at any time unless an event of default under the
Subordinated Indenture has occurred and is continuing with respect to the
Series B Junior Subordinated Notes. If such an event of default has occurred
and is continuing, the holders of a majority of the Preferred Securities may
remove the Property Trustee and the Delaware Trustee. Removal of the Property
Trustee or the Delaware Trustee will become effective when the successor
trustee accepts its appointment.

  If an event of default under the Subordinated Indenture with respect to the
Series B Junior Subordinated Notes has occurred and is continuing, the holders
of Preferred Securities will have a preference over the holders of Common
Securities if the Trust is dissolved.

  The Property Trustee will notify the holders of the Preferred Securities of
any notice of default that it receives from the Indenture Trustee with respect
to the Series B Junior Subordinated Notes.

Voting Rights

  So long as the Property Trustee holds any Series B Junior Subordinated Notes,
the Securities Trustees will not:

  . direct the time, method and place of conducting any proceeding for any
    remedy available to the Indenture Trustee, or exercising any power of the
    Indenture Trustee with respect to the Series B Junior Subordinated Notes;

  . consent to waive any past default under the Subordinated Indenture;

  . exercise any right to rescind or annul a declaration that the principal
    of all the Series B Junior Subordinated Notes will be due and payable; or

  . consent to any amendment, modification or termination of the Subordinated
    Indenture or the Series B Junior Subordinated Notes, if that consent is
    required, or to any other action, as the holder of the Series B Junior
    Subordinated Notes, under the Subordinated Indenture,

without obtaining the prior approval of the holders of at least 66 2/3% of the
outstanding Preferred Securities. When the Subordinated Indenture requires the
consent of each holder of Series B Junior Subordinated Notes affected, the
Securities Trustees will not give that consent without the prior consent of
each holder of outstanding Preferred Securities. The Securities Trustees may
not revoke any action that the holders of the Preferred Securities have
authorized or approved.

  If any proposed amendment to the Trust Agreement provides for any of the
following or the Securities Trustees propose to effect:

  . any action that would adversely affect the powers, preferences or special
    rights of the Preferred Securities; or

  . the dissolution, winding-up or termination of the Trust, other than
    pursuant to the Trust Agreement,

then the holders of outstanding Preferred Securities will have the right to
vote as a class on that amendment or proposal. The amendment or proposal will
be effective only if at least 66 2/3% of the outstanding Preferred Securities
approve it. Holders of Preferred Securities may provide their approval at a
meeting convened for that purpose or by written consent.

                                      S-20
<PAGE>

  Any Preferred Securities that Duke Energy, the Administrative Trustees, or
any affiliate of Duke Energy or an Administrative Trustee owns, whether of
record or beneficially, will be treated as not outstanding for purposes of a
vote or consent.

  The holders of the Preferred Securities will have no other voting rights
except those described under the caption "--Amendment of the Trust Agreement"
in this Prospectus Supplement and those described under the captions
"Amendments and Assignment" and "Events of Default" in "Description of the
Guarantees" in the accompanying Prospectus and any other voting rights
otherwise required by law and the Trust Agreement.

Co-Property Trustees and Separate Property Trustees

  Duke Energy, as the holder of the Common Securities, and the Property Trustee
will have the power to appoint one or more co-property trustees or separate
property trustees for all or part of the Trust Property for the purpose of
meeting certain legal requirements, including the legal requirements of any
jurisdiction in which part of the Trust Property is located. The Property
Trustee will have the power to make the appointment alone if Duke Energy, as
depositor, does not join in the appointment within 15 days after it receives a
request to do so, or in case an event of default under the Subordinated
Indenture with respect to the Series B Junior Subordinated Notes has occurred
and is continuing.

Amendment of the Trust Agreement

  Duke Energy and the Securities Trustees may amend the Trust Agreement without
the consent of the holders of the Trust Securities:

  . to cure any ambiguity or to make any corrections or additions that are
    not inconsistent with the other provisions of the Trust Agreement that do
    not adversely affect the interests of any holder of Trust Securities in
    any material respect; or

  . to modify, eliminate or add to any provisions of the Trust Agreement to
    the extent necessary to ensure that the Trust will not be classified as
    other than a grantor trust for United States federal income tax purposes.

  The Trust or the Securities Trustees may make other amendments to the Trust
Agreement if:

  . the holders of at least 66 2/3% of the outstanding Trust Securities
    approve the amendment; and

  . the Securities Trustees receive an opinion of counsel to the effect that
    the amendment will not affect the Trust's status as a grantor trust or
    the Trust's exemption from the Investment Company Act of 1940.

  The consent of each affected holder of Trust Securities will be required to
amend the Trust Agreement to:

  . change the amount or timing of any distribution or any payment upon
    redemption, or otherwise adversely affect the amount of any distribution
    or any payment upon redemption required to be made on the Trust
    Securities as of a specified date;

                                      S-21
<PAGE>

  . restrict the right of a holder of Trust Securities to sue to enforce any
    of those payments on or after that date;

  . change the purpose of the Trust;

  . authorize the issuance of any additional beneficial interests in the
    Trust; or

  . change the consent required to amend the Trust Agreement.

Mergers, Consolidations, Replacements, Transfers

  The Trust may not consolidate, amalgamate, merge with or into or be replaced
by any corporation or other entity, or convey, transfer or lease substantially
all of its properties and assets to any corporation or other entity, except as
described below. At Duke Energy's request but without the consent of the
holders of the Trust Securities, the Trust may consolidate, amalgamate, merge
with or into, or be replaced by a trust organized under the laws of any state,
if:

  . the successor entity either:

   . expressly assumes all the Trust's obligations with respect to the Trust
     Securities; or

   . substitutes other securities having substantially the same terms as the
     Trust Securities for the Preferred Securities and the Common Securities
     so long as those other securities--called "Successor Securities" in
     this Prospectus Supplement--rank equal in priority with the Trust
     Securities with respect to distributions and payments upon liquidation,
     redemption and otherwise;

  . Duke Energy expressly appoints a trustee of the successor entity,
    possessing the same powers and duties as the Property Trustee as the
    holder of the Series B Junior Subordinated Notes;

  . the Preferred Securities or any Successor Securities are listed on any
    national securities exchange or other organization on which the Preferred
    Securities are then listed, or any Successor Securities will be so listed
    upon notification of issuance;

  . the consolidation, amalgamation, merger or replacement does not cause the
    Preferred Securities, including any Successor Securities, to be
    downgraded by any nationally recognized statistical rating organization;

  . the consolidation, amalgamation, merger or replacement does not adversely
    affect the rights, preferences and privileges of the holders of the Trust
    Securities, including any Successor Securities, in any material respect;

  . the successor entity has a purpose substantially identical to that of the
    Trust;

  . prior to the consolidation, amalgamation, merger or replacement, Duke
    Energy and the Property Trustee have received an opinion of counsel to
    the effect that:

   . the transaction does not adversely affect the rights, preferences and
     privileges of the holders of the Trust Securities, including any
     Successor Securities, in any material respect; and

   . following the transaction, neither the Trust nor the successor entity
     will be required to register as an "investment company" under the
     Investment Company Act of 1940; and

                                      S-22
<PAGE>

  . Duke Energy owns all the common securities of the successor entity and
    guarantees the obligations of the successor relating to the Successor
    Securities at least to the extent provided by the Guarantee.

However, the Trust may not enter into any of the mergers, consolidations or
other transactions mentioned above if that transaction would cause the Trust or
its successor entity to be classified as other than a grantor trust for United
States federal income tax purposes except with the consent of the holders of
all the Trust Securities.

Payments; Paying Agent

  So long as DTC is the securities depositary for the Preferred Securities,
payments on the Preferred Securities will be made to DTC or its nominee and DTC
will credit the relevant accounts at DTC on the applicable distribution dates.
If DTC or its nominee no longer holds the Preferred Securities, the paying
agent will make payments on the Preferred Securities by check mailed to the
address of the holder entitled to the payment as that address appears in the
security register for the Preferred Securities.

  The paying agent will initially be the Property Trustee. The paying agent
will be permitted to resign as paying agent if it gives 30 days' written notice
to the Administrative Trustees and Duke Energy. The Administrative Trustees
will appoint a successor paying agent in the event of any such resignation.

Transfers; Registrar and Transfer Agent

  There will be no service charge for registration of transfers of any
Preferred Securities. However, payment of any tax or other governmental charges
may be required in connection with a transfer. The registrar and transfer agent
for the Preferred Securities will not be required to register any transfer of
Preferred Securities that have been called for redemption.

  Duke Energy and the Trust anticipate that the Property Trustee or one of its
affiliates will act as registrar and transfer agent for the Preferred
Securities.

Information Concerning the Property Trustee

  Before an event of default occurs under the Trust Agreement, the Property
Trustee will perform only those duties that are expressly specified in the
Trust Agreement. After any default, the Property Trustee will exercise the same
degree of care as a prudent person would exercise in the conduct of his or her
own affairs. Subject to these provisions, the Property Trustee is under no
obligation to exercise any of the powers vested in it by the Trust Agreement at
the request of any holder of Preferred Securities, unless that holder offers
the Property Trustee reasonable indemnity against the costs, expenses and
liabilities that the Property Trustee might incur as a result.

  The Chase Manhattan Bank is the Property Trustee. The Chase Manhattan Bank is
also the Indenture Trustee and the Guarantee Trustee and serves as Trustee
under Duke Energy's First and Refunding Mortgage and its Senior Indenture. Duke
Energy and certain of its affiliates maintain deposit accounts and banking
relationships with The Chase Manhattan Bank. The Chase Manhattan Bank serves as
trustee under other indentures pursuant to which securities of Duke Energy and
affiliates of Duke Energy are outstanding.

                                      S-23
<PAGE>

Miscellaneous

  The Trust Agreement directs the Administrative Trustees to operate the Trust
so that the Trust will not be:

  . deemed to be an "investment company" that is required to be registered
    under the Investment Company Act of 1940; or

  . treated as other than a grantor trust for United States federal income
    tax purposes.

The Trust Agreement also directs the Administrative Trustees to operate the
Trust so that the Series B Junior Subordinated Notes will be treated as
indebtedness of Duke Energy for United States federal income tax purposes. The
Trust Agreement authorizes the Administrative Trustees and Duke Energy to take
any action not inconsistent with applicable law, the Trust's certificate of
trust or the Trust Agreement, that they determine to be necessary or desirable
for those purposes. No such action may, however, materially and adversely
affect the interests of the holders of the Preferred Securities.

  Duke Energy and its affiliates may purchase outstanding Preferred Securities
by tender, in the open market or by private agreement, to the extent legally
permitted.

             DESCRIPTION OF THE SERIES B JUNIOR SUBORDINATED NOTES

  The following description of the Series B Junior Subordinated Notes is only a
summary and is not intended to be comprehensive. The description should be read
together with the description of the general terms and provisions of the Junior
Subordinated Notes provided under the caption "Description of the Junior
Subordinated Notes" in the accompanying Prospectus.

General

  Duke Energy will issue the Series B Junior Subordinated Notes as a series of
Subordinated Notes under the Subordinated Indenture. The Series B Junior
Subordinated Notes will be limited in principal amount to $257,731,975, which
is the liquidation amount of the Trust Securities.

  The Series B Junior Subordinated Notes will mature and become due and
payable, together with any accrued and unpaid interest, including any
Additional Interest, on March 31, 2039.

  The Series B Junior Subordinated Notes will rank equal in priority with any
other series of Junior Subordinated Notes issued under the Subordinated
Indenture.

  The Series B Junior Subordinated Notes are not subject to any sinking fund
provision.

Optional Redemption

  Duke Energy will have the right to redeem the Series B Junior Subordinated
Notes:

  . from time to time, in whole or in part, on or after June 30, 2004; or

  . at any time, in whole but not in part, during the 90 days after the
    occurrence of a Special Event.

Duke Energy may redeem the Series B Junior Subordinated Notes upon not less
than 30 nor more than 60 days' notice at a redemption price equal to the
principal amount to be redeemed plus any accrued and unpaid interest, including
any Additional Interest, to the redemption date.

  If a partial redemption of the Series B Junior Subordinated Notes would cause
the Preferred Securities to be delisted, Duke Energy will be required to redeem
all of the Series B Junior Subordinated Notes.

Interest

  The Series B Junior Subordinated Notes will bear interest at a yearly rate of
7.20% from the original issue date. Interest on the Series B Junior
Subordinated Notes will be payable quarterly in arrears on March 31, June 30,
September 30 and December 31 of each year, commencing on September 30, 1999,
unless the applicable interest period is extended. Interest will be payable to
the person or persons in whose name the Series B Junior Subordinated Notes are
registered at the close of business on the 15th calendar day before the
relevant interest payment date, except that interest payable on the maturity
date or on a redemption date will be paid to the person to whom principal is
payable. Interest will be computed on the basis of a 360-day year of twelve 30-
day months.

                                      S-25
<PAGE>

  If any date on which interest is payable on the Series B Junior Subordinated
Notes is not a Business Day, the interest payable on that date will be paid on
the next day that is a Business Day (without any interest or other payment due
to the delay), except that if that Business Day falls in the next calendar
year, interest will be paid on the immediately preceding Business Day.

Option to Extend Interest Payment Period

  Duke Energy will have the right, at any time and from time to time, to defer
interest payments on the Series B Junior Subordinated Notes by extending the
interest payment period for up to 20 consecutive quarters, but not beyond the
maturity date. When the extension period has ended, Duke Energy will pay all
accrued and unpaid interest, including any Additional Interest, on the next
interest payment date. Before any extension period ends, Duke Energy may
further defer interest payments by extending the interest payment period.
However, an extension period, together with any previous and further
extensions, may not exceed 20 consecutive quarters. During an extension period,
Duke Energy will have the right to make partial payments of interest on any
interest payment date. After an extension period terminates and all amounts due
are paid, Duke Energy may select a new extension period, subject to the
previously mentioned requirements.

  Duke Energy has no present intention of exercising its right to defer
payments by extending the interest payment period on the Series B Junior
Subordinated Notes.

  Duke Energy will notify the holder or holders of the Series B Junior
Subordinated Notes and the Indenture Trustee of its selection or extension of
an extension period at least one Business Day before the earlier of:

  . the record date for the interest payment date on which the extension
    period is to begin or the record date for the interest payment date on
    which the extension period that is being extended would otherwise
    terminate; or

  . the date that Duke Energy or the Trust is required to give notice to the
    New York Stock Exchange or other self-regulatory organization of the
    record date or the date those distributions are payable.

Additional Interest

  "Additional Interest" means:

  . those additional amounts as may be required so that the net amounts that
    a holder of Series B Junior Subordinated Notes (if the holder is the
    Trust) receives and retains after paying taxes, duties, assessments or
    governmental charges of whatever nature (other than withholding taxes)
    imposed by the United States or any other taxing authority will not be
    less than the amounts the holder would have received had no such taxes,
    duties, assessments or other governmental charges been imposed; and

  . interest on interest due but not paid on an interest payment date for the
    Series B Junior Subordinated Notes, accruing at a yearly rate of 7.20%
    from the applicable interest payment date to the date of payment,
    compounded quarterly, on each interest payment date, to the extent
    legally permitted.

                                      S-26
<PAGE>

Certain Covenants

  Duke Energy will covenant, for the benefit of the holders of Series B Junior
Subordinated Notes and the holders of the Preferred Securities, that:

  . if it has given notice of its election to extend an interest payment
    period for the Series B Junior Subordinated Notes and the extension is
    continuing; or

  . if an event of default under the Subordinated Indenture with respect to
    the Series B Junior Subordinated Notes has occurred and is continuing,

then it will not:

  . declare or pay any dividend or make any distributions with respect to any
    of its capital stock, or redeem, purchase, acquire or make a liquidation
    payment with respect to any of its capital stock; or

  . make any payment of interest, principal or premium on any debt
    securities, including guarantees other than the Guarantee, issued by it
    which rank equal in priority with or junior to the Series B Junior
    Subordinated Notes, or repay, repurchase or redeem any such debt
    securities.

  However, those covenants will not restrict:

  . any action described in the preceding sentence that results from a
    reclassification of Duke Energy's capital stock or the exchange or
    conversion of one class or series of Duke Energy's capital stock for
    another class or series;

  . the declaration and payment of a dividend or distribution or similar
    share purchase rights in the future;

  . repurchases, redemptions or other acquisitions of shares of Duke Energy's
    capital stock in connection with an employment contract, benefit plan or
    other similar arrangement with or for the benefit of employees, officers
    or directors, or a stock purchase and dividend reinvestment plan;

  . acquisitions of shares of Duke Energy's capital stock in connection with
    the issuance of shares of Duke Energy's capital stock (or securities
    convertible into or exchangeable for shares of Duke Energy's capital
    stock) as consideration in an acquisition transaction entered into before
    the beginning of the relevant extension period;

  . dividends or distributions in Duke Energy's capital stock;

  . the purchase of fractional interests in shares of Duke Energy's capital
    stock under the conversion or exchange provisions of that capital stock
    or the security being converted or exchanged; or

  . mandatory sinking fund payments with respect to any series of Duke
    Energy's preferred stock or preferred stock A, if the aggregate stated
    value of all such series outstanding at the time of the payment does not
    exceed 5% of the sum of:

   . the principal amount of all bonds or other securities representing
     secured indebtedness issued or assumed by Duke Energy and then
     outstanding; and

                                      S-27
<PAGE>

   . Duke Energy's capital and surplus to be stated on its books of account
     after giving effect to that payment.

   Any money deposited into any sinking fund that is not in violation of
   this provision may thereafter be applied to the purchase or redemption of
   that preferred stock or preferred stock A in accordance with the terms of
   that sinking fund without regard to the foregoing restrictions.

  Duke Energy will also covenant that, for so long as the Trust Securities are
outstanding, it will:

  . continue to own all the Common Securities directly or indirectly; and

  . use its reasonable efforts to cause the Trust:

   . to remain a statutory business trust, except in connection with the
     distribution of Series B Junior Subordinated Notes in liquidation of
     the Trust, the redemption of all the Trust Securities, or certain
     mergers, consolidations or amalgamations; and

   . to otherwise continue to be classified as a grantor trust for United
     States federal income tax purposes.

Any successor of Duke Energy may, however, succeed to Duke Energy's ownership
of the Common Securities without Duke Energy's violating this covenant if the
successor is permitted under the Subordinated Indenture.

Book-Entry Issuance

  Duke Energy expects that the Series B Junior Subordinated Notes will be
issued in the form of one or more global certificates registered in the name of
the securities depositary or its nominee if the Series B Junior Subordinated
Notes are distributed to holders of Trust Securities in connection with the
voluntary or involuntary dissolution, winding-up or liquidation of the Trust.
The procedures applicable to the transfer and payment of the Series B Junior
Subordinated Notes are expected to be substantially similar to those applicable
to the transfer and payment of the Preferred Securities.

Form; Denominations

  The Series B Junior Subordinated Notes will be issuable in registered form
without coupons. The Series B Junior Subordinated Notes will be issuable in
denominations of $25 or multiples of $25.

Defeasance

  The Series B Junior Subordinated Notes will be subject to Defeasance but not
to Covenant Defeasance.

Miscellaneous

  Duke Energy will have the right to assign any of its rights or obligations
under the Subordinated Indenture with respect to the Series B Junior
Subordinated Notes to one of its direct or indirect wholly owned subsidiaries.
Duke Energy will remain primarily liable for the performance of those
obligations in the event of an assignment.

                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
            THE SERIES B JUNIOR SUBORDINATED NOTES AND THE GUARANTEE

  As long as Duke Energy makes interest and other payments on the Series B
Junior Subordinated Notes when due, those payments will be sufficient to cover
distributions and payments due on the Preferred Securities and the Common
Securities. This is the case primarily because:

  . the total principal amount of the Series B Junior Subordinated Notes will
    be equal to the total liquidation amount of the Trust Securities;

  . the interest rate and interest and other payment dates on the Series B
    Junior Subordinated Notes will correspond to the distribution rate and
    distribution and other payment dates for the Preferred Securities;

  . the Agreement as to Expenses and Liabilities between Duke Energy and the
    Trust provides that Duke Energy will pay all costs and expenses of the
    Trust; and

  . the Trust Agreement provides that the Securities Trustees will not permit
    the Trust to engage in any activity that is inconsistent with the
    purposes of the Trust.

  If Duke Energy does not make the required payments on the Series B Junior
Subordinated Notes, it is expected that the Trust will not have sufficient
funds to make the related distributions on the Preferred Securities. Duke
Energy will guarantee payments of distributions and other payments due on the
Preferred Securities but only to the extent that the Trust has funds legally
and immediately available for the payment of those distributions and other
payments.

  If an event of default under the Subordinated Indenture with respect to the
Series B Junior Subordinated Notes occurs and is continuing, then:

  . the holders of Preferred Securities will rely on the Property Trustee, as
    the holder of the Series B Junior Subordinated Notes, to enforce its
    rights against Duke Energy; and

  . the holders of a majority of the Preferred Securities will have the right
    to direct the time, method and place of conducting any proceeding for any
    remedy available to the Property Trustee or to direct the exercise of any
    power of the Property Trustee under the Trust Agreement, including the
    right to direct the Property Trustee to exercise the remedies available
    to it as a holder of the Series B Junior Subordinated Notes.

  If the Property Trustee fails to enforce its rights under the Series B Junior
Subordinated Notes, a holder of Preferred Securities may, to the extent legally
permitted, institute a legal proceeding against Duke Energy to enforce its
rights under the Trust Agreement without first instituting a legal proceeding
against the Property Trustee, the Trust or any other person or entity. However,
a holder of Preferred Securities may institute a legal proceeding directly
against Duke Energy to enforce payment to that holder of principal or interest
on Series B Junior Subordinated Notes having a principal amount equal to the
liquidation amount of the Preferred Securities of that holder on or after the
due dates specified in the Series B Junior Subordinated Notes. The Trust
Agreement also provides a mechanism whereby the holders of Preferred Securities
may appoint a substitute Property Trustee if an event of default under the
Subordinated Indenture with respect to the Series B Junior Subordinated Notes
occurs and is continuing.

                                      S-29
<PAGE>

  The Guarantee provides a mechanism whereby the holders of the Preferred
Securities may direct the Guarantee Trustee to enforce its rights under the
Guarantee if Duke Energy fails to make payments under the Guarantee. In
addition, any holder of Preferred Securities may institute a legal proceeding
directly against Duke Energy to enforce the Guarantee Trustee's rights under
the Guarantee without first instituting a legal proceeding against the
Guarantee Trustee or any other person or entity.

  The Guarantee, the Subordinated Indenture, the Series B Junior Subordinated
Notes, the Trust Agreement and the Agreement as to Expenses and Liabilities
provide a full and unconditional guarantee, subject to certain subordination
provisions, by Duke Energy of the payments due on the Preferred Securities.

  The holders of Preferred Securities will be entitled to receive the
Liquidation Distribution in cash, out of assets legally available for
distribution to those holders, upon any voluntary or involuntary dissolution,
winding-up or termination of the Trust unless the Series B Junior Subordinated
Notes are distributed in connection with those events. Upon any voluntary or
involuntary liquidation or bankruptcy of Duke Energy, the Property Trustee, as
holder of the Series B Junior Subordinated Notes, would be a subordinated
creditor of Duke Energy, subordinated in right of payment to all Senior
Indebtedness, but entitled to receive payment in full of principal and interest
before any of Duke Energy's shareholders receive payments or distributions.
Because Duke Energy is guarantor under the Guarantee and has agreed to pay all
costs, expenses and liabilities of the Trust under the Agreement as to Expenses
and Liabilities, other than the Trust's obligations to holders of the Preferred
Securities, the positions of a holder of Preferred Securities and a holder of
Series B Junior Subordinated Notes relative to other creditors and Duke
Energy's shareholders would be substantially the same in the event of the
liquidation or bankruptcy of Duke Energy.

  A default or event of default under any Senior Indebtedness is not a default
or an event of default under the Subordinated Indenture. However, if a default
occurs with respect to Senior Indebtedness or if Senior Indebtedness is
accelerated, the subordination provisions of the Series B Junior Subordinated
Notes provide that no payments may be made in respect of the Series B Junior
Subordinated Notes:

  . until that Senior Indebtedness has been paid in full, in the case of any
    payment by, or distribution of assets of, Duke Energy to creditors upon a
    dissolution, winding-up, liquidation or reorganization of Duke Energy; or

  . until all amounts due on that Senior Indebtedness have been paid, in the
    case of a payment default beyond any grace period under that Senior
    Indebtedness or the acceleration of that Senior Indebtedness because of a
    default with respect to that Senior Indebtedness.

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

  Following is the opinion of Dewey Ballantine LLP, counsel to Duke Energy and
the Trust, as to the material United States federal income tax consequences of
the purchase, ownership and disposition of Preferred Securities by holders that
acquire Preferred Securities on their original issue at the initial offering
price and that hold the Preferred Securities as capital assets. The opinion
does not address all tax consequences that may be important to a holder in
light of the holder's peculiar

                                      S-30
<PAGE>

circumstances or to holders subject to special rules, such as financial
institutions, foreign persons, real estate investment trusts, regulated
investment companies, insurance companies, tax-exempt organizations, dealers in
securities or currencies, individual retirement and other tax deferred
accounts, and persons engaging in straddles or hedges relating to Preferred
Securities. This discussion is based on legal authorities that are subject to
change at any time in a manner that could adversely affect holders. Prospective
investors in Preferred Securities should consult their own tax advisors with
regard to the application of the tax considerations discussed below to their
own situations as well as the application of any state, local or other tax
laws.

  The Trust will be disregarded for federal income tax purposes and each holder
of Preferred Securities will be treated as the owner of a proportionate amount
of the Series B Junior Subordinated Notes held by the Trust. Accordingly, a
holder will include in income the holder's share of the income from the Series
B Junior Subordinated Notes. Duke Energy believes that the likelihood of the
occurrence of an extension period is remote and accordingly that under
applicable income tax regulations the Series B Junior Subordinated Notes should
not be treated as issued with original issue discount. These regulations have
not been addressed in any rulings or other interpretations by the Internal
Revenue Service and it is possible that the Internal Revenue Service could take
a contrary position. If, however, Duke Energy exercises its option to defer
payments of interest, the Series B Junior Subordinated Notes would at that time
be treated as issued with original issue discount and all the stated interest
payments on the Series B Junior Subordinated Notes would thereafter be treated
as original issue discount. As a result, holders would be required to accrue
original issue discount income on an economic accrual basis, even if the holder
uses the cash method of accounting for tax purposes and even though holders
will not receive any payments during the extension period. Because income on
the Preferred Securities will constitute interest or original issue discount,
corporate holders will not be entitled to a dividends-received deduction with
respect to any income from the Preferred Securities.

  Upon a sale, retirement or other taxable disposition of Preferred Securities,
a holder will recognize gain or loss equal to the difference between the amount
realized on the sale, retirement or other disposition and the holder's adjusted
tax basis in the Preferred Securities. If the holder disposes of Preferred
Securities prior to the occurrence of an extension period, any portion of the
amount received that is attributable to accrued interest will be treated as
interest income to the holder and will not be treated as part of the amount
realized for purposes of determining gain or loss on the disposition of the
Preferred Securities. Any recognized gain or loss will be capital gain or loss
and will be long-term capital gain or loss if the holding period for the
Preferred Securities is more than one year at the time of sale, retirement or
other disposition.

  Income on Preferred Securities will be reported to holders on Form 1099,
which form should be mailed to holders of Preferred Securities by January 31
following each calendar year. A holder will generally be required to furnish a
social security number or other taxpayer identification number in order to
avoid "backup withholding" tax on distributions on the Preferred Securities and
payment of the proceeds from the disposition of Preferred Securities. Any
amount so withheld will be allowed as a refund or a credit against the holder's
United States federal income tax liability, provided the required information
is furnished to the Internal Revenue Service.


                                      S-31
<PAGE>

  The United States federal income tax discussion set forth above may not be
applicable to a holder, depending upon the holder's particular situation, and
therefore each holder should consult a tax advisor with respect to the tax
consequences of the ownership and disposition of Preferred Securities,
including the tax consequences under state, local, foreign and other tax laws
and the possible effects of changes in federal or other tax law.

</TABLE>

  The Underwriters are obligated to take and pay for the total number of
Preferred Securities offered hereby if any such Preferred Securities are
purchased. In the event of default by any Underwriter, the Underwriting
Agreement provides that, in certain circumstances, purchase commitments of the
non-defaulting Underwriters may be increased or the Underwriting Agreement may
be terminated.

  The Underwriting Agreement provides that the Trust and Duke Energy will
indemnify the several Underwriters against certain liabilities, including
liabilities under the Securities Act of 1933.

  In view of the fact that the proceeds of the sale of the Preferred Securities
will ultimately be used to purchase the Series B Junior Subordinated Notes, the
Underwriting Agreement provides that Duke Energy will pay as compensation to
the Underwriters $0.7875 per Preferred Security for the accounts of the several
Underwriters ($7,875,000 in the aggregate).

  The Underwriters propose to offer the Preferred Securities, in part, directly
to the public at the public offering price set forth on the cover page of this
Prospectus Supplement, and to certain dealers at a price that represents a
concession not in excess of $0.50. The Underwriters may allow, and such dealers
may reallow, a concession not in excess of $0.45 per Preferred Security to
certain brokers and dealers. After the Preferred Securities are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives of the Underwriters.

  The Preferred Securities have been approved for listing on the New York Stock
Exchange, subject to official notice of issuance. Trading of the Preferred
Securities on the New York Stock Exchange is expected to begin within 30 days
after the original issue date of the Preferred Securities. The representatives
of the Underwriters have advised Duke Energy and the Trust that they intend to
make a market in the Preferred Securities before trading on the New York Stock
Exchange begins. The representatives of the Underwriters will have no
obligation to make a market in the Preferred Securities, however, and may cease
market making activities, if commenced, at any time.

  There has been no public market for the Preferred Securities before this
offering. In order to meet one of the requirements for listing the Preferred
Securities on the New York Stock Exchange, the Underwriters will undertake to
sell lots of 100 or more Preferred Securities to a minimum of 400 beneficial
holders.

                                      S-34
<PAGE>

  The Underwriters may engage in over-allotment, stabilizing transactions and
covering transactions in accordance with Regulation M under the Securities
Exchange Act of 1934. Over-allotment involves sales in excess of the offering
size, which creates a short position for the Underwriters. Stabilizing
transactions involve bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. Covering transactions
involve purchases of the Preferred Securities in the open market after the
distribution has been completed in order to cover short positions. Such
stabilizing transactions and covering transactions may cause the price of the
Preferred Securities to be higher than it would otherwise be in the absence of
such transactions.

  Duke Energy estimates that it will spend approximately $397,500 for printing,
listing, rating agency fees, trustees' fees, legal fees and other expenses of
the offering.

  The Underwriters and certain of their affiliates have engaged, and will in
the future engage, in investment banking transactions with Duke Energy and
certain of its affiliates in the ordinary course of their business.

                           VALIDITY OF THE SECURITIES

  Richards, Layton & Finger, P.A., special Delaware counsel to Duke Energy and
the Trust, will issue an opinion about the validity of the Preferred Securities
under Delaware law on behalf of Duke Energy and the Trust. Dewey Ballantine LLP
will issue an opinion about the validity of the Series B Junior Subordinated
Notes, the Guarantee and certain related matters as well as certain matters
relating to United States federal income tax considerations on behalf of Duke
Energy and the Trust. Ellen T. Ruff, Esq., who is Duke Energy's Vice President
and General Counsel, Corporate, Gas and Electric Operations, will pass upon
certain matters of North Carolina law on behalf of Duke Energy. As of May 31,
1999, Ms. Ruff owned 8,714 shares of Duke Energy's common stock and options to
purchase 25,400 shares of Duke Energy's common stock, 2,325 of which were
exercisable. Brown & Wood LLP will issue an opinion about the validity of the
Series B Junior Subordinated Notes and the Guarantee for the Underwriters.

  This Prospectus is part of a Registration Statement that Duke Energy, Duke
Energy Capital Trust II, Duke Energy Capital Trust III and Duke Energy Capital
Trust IV filed with the Securities and Exchange Commission ("SEC") utilizing a
"shelf" registration process. Under the shelf registration process, Duke Energy
Capital Trust II, Duke Energy Capital Trust III and Duke Energy Capital Trust
IV may issue trust preferred securities in one or more offerings up to a total
dollar amount of $500,000,000. Those trust preferred securities are called
"Preferred Securities" in this Prospectus.

  This Prospectus provides a general description of the Preferred Securities.
Each time Preferred Securities are sold, a Prospectus Supplement will provide
specific information about the terms of that offering. The Prospectus
Supplement may also add, update or change information contained in this
Prospectus. The Registration Statement filed with the SEC includes exhibits
that provide more details about the matters discussed in this Prospectus. You

directly or exclusively relate to historical facts. Such statements are
"forward-looking statements" within the meaning of the Private Securities

statements by the use of forward-looking words, such as "may," "will," "could,"
"project," "believe," "anticipate," "expect," "estimate," "continue,"
"potential," "plan," "forecast" and the like. Those statements represent Duke
Energy's intentions, plans, expectations and beliefs about future events and

are outside Duke Energy's control and could cause actual results to differ
materially from the results expressed or implied by those forward-looking
statements. Those factors include:

     cost and investment recovery, have an impact on rate structures, and
     affect the speed and degree to which competition enters the electric and
     natural gas industries;

  .  industrial, commercial and residential growth in Duke Energy's service
     territories or the service territories of Duke Energy's subsidiaries;

  .  the weather and other natural phenomena;

     Energy and its subsidiaries are subject or other external factors over
     which Duke Energy has no control;

  .  achievement of Year 2000 readiness; and

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

  Duke Energy undertakes no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. In light of these risks, uncertainties and assumptions,
the forward-looking events referred to in this Prospectus and any accompanying
Prospectus Supplement might not occur.

  Natural Gas Transmission, through its northeast pipelines, provides
interstate transportation and storage of natural gas for customers primarily in
the Mid-Atlantic and New England states. Until the sale of the midwest
pipelines to a subsidiary of CMS Energy Corporation, which was consummated on
March 29, 1999, Natural Gas Transmission provided interstate transportation and
storage services in the midwest states.

  Field Services gathers, processes, transports and markets natural gas and
produces and markets natural gas liquids. Field Services operates gathering
systems in ten states that serve major gas-producing regions in the Rocky
Mountains, Permian Basin, Mid-Continent and Gulf Coast areas. Field Services

the natural gas gathering, processing, fractionation and natural gas liquids
pipeline business of a unit of Union Pacific Resources.

  Trading and Marketing markets natural gas, electricity and other energy-
related products across North America. Duke Energy owns a 60% interest in
Trading and Marketing, with Mobil Corporation owning a 40% minority interest.

interests. PanEnergy Corp was involved in the gathering, processing,
transportation and storage of natural gas, the production of natural gas
liquids and the marketing of natural gas, electricity and other energy-related
products.

                                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 Energy will use the net proceeds
from that investment:

  .  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.

If Duke Energy does not use the net proceeds immediately, it may temporarily
invest them in short-term interest-bearing obligations or deposit them with
banks.

                                   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 Delaware. 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. Each
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 Delaware 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 current
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.

<PAGE>

                              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 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.

  You should refer to the applicable Prospectus Supplement for the terms of any
series of Preferred Securities, including:

  .  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.

                         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.

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.

                                       9
<PAGE>

  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 only apply 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 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.

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. See "Duke Energy Corporation--Recent
Financial Data" for additional information about those securities.

  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.

                                       10
<PAGE>

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 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 and the Trustee under the Subordinated Indenture. The Chase Manhattan
Bank also serves as trustee under Duke Energy's First and Refunding Mortgage
and its Senior Indenture. Duke Energy and certain of its affiliates maintain
deposit accounts and banking relationships with The Chase Manhattan Bank. The
Chase Manhattan Bank serves as trustee under other indentures pursuant to which
securities of Duke Energy and affiliates of Duke Energy 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

                                       11
<PAGE>

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.

                  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 called the "Subordinated Indenture" in this
Prospectus. The Trustee under the Subordinated Indenture is called the
"Trustee" in this Prospectus. The Subordinated Indenture is an exhibit to the
Registration Statement.

  The Junior Subordinated Notes are unsecured obligations of Duke Energy. As of
March 31, 1999, Duke Energy had approximately $2,300,000,000 of secured
indebtedness outstanding. The Junior Subordinated Notes are also 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 the
caption "Subordination" in this Prospectus.

  Duke Energy conducts its non-electric operations, and certain of its electric
operations outside its service area in the Carolinas, through subsidiaries.
Accordingly, Duke Energy's 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. Duke Energy
anticipates that certain of its subsidiaries will incur substantial amounts of
debt in the expansion of their businesses.

  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 Duke Energy's Board of Directors or a duly
authorized committee authorizing the issuance. The form of supplemental
indenture to the Subordinated Indenture is an exhibit to the Registration
Statement.

  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.

                                       12
<PAGE>

  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 will specify the terms of that series, including, if applicable:

  .  the title of the series;

  .  any limit on the 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;

  .  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, if other than the
     principal corporate trust office of the Trustee;

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

  .  whether the provisions described under the caption "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;

                                       13
<PAGE>

  .  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 the applicable Prospectus Supplement states otherwise, 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. Transfers and exchanges of the Junior
Subordinated Notes may be made at The Chase Manhattan Bank, 55 Water Street,
New York, New York 10041.

  The Junior Subordinated Notes will be issuable in denominations of $1,000 and
any multiples of $1,000, unless the applicable Prospectus Supplement states
otherwise.

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 certificate 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.

                                       14
<PAGE>

  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 Trustee;

  .  the Trust;

  .  any agent of any of the above.

Redemption

  Any provisions relating to the redemption of Junior Subordinated Notes will
be set forth in the applicable Prospectus Supplement. Unless the applicable
Prospectus Supplement states otherwise, 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, issued

                                       15
<PAGE>

under it, and Duke Energy must deliver an officers' certificate and an opinion
of counsel to the Trustee 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 the Subordinated Notes issued
under it.

Modification; Waiver

  Duke Energy may amend or modify the Subordinated Indenture with the consent
of the holders of a majority of the outstanding Subordinated Notes of all
series issued under it that are affected by the amendment or 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 amend or modify the Subordinated Indenture, to waive
     compliance with certain restrictive provisions of the Subordinated
     Indenture or to waive certain defaults; or

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

  Duke Energy may supplement the Subordinated Indenture to create new series of
Junior Subordinated Notes and for other purposes, without the consent of any
holders of Subordinated Notes, including Junior Subordinated Notes.

  The holders of a majority 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 Indenture under which those Junior
Subordinated Notes were issued. The holders of a majority of the outstanding
Subordinated Notes of all series under the Subordinated Indenture with respect
to which a default has occurred and is continuing, all holders of those series
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 amended or 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.

                                       16
<PAGE>

Events of Default

  The following are events of default under the Subordinated Indenture with
respect to any series of Junior Subordinated Notes, unless the applicable
Prospectus Supplement states otherwise:

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

  .  failure to pay any interest on any Junior Subordinated Note of that
     series, when due, 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 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 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 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.

  Additional events of default may be established for a particular series and,
if established, 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 Trustee or the holders of at least 33% 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 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 Trustee under the Subordinated Indenture; and

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

  A holder of Preferred Securities may institute a legal proceeding directly
against Duke Energy, without first instituting a legal proceeding against the
Property Trustee 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.


                                       17
<PAGE>

  The 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 Trustee security or indemnity against the costs,
expenses and liabilities which it might incur as a result. The holders of a
majority 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 Trustee or the
exercise of any power of the Trustee with respect to those Junior Subordinated
Notes. The 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 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 Trustee an officers'
certificate 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. Unless the applicable
Prospectus Supplement states otherwise, the paying agent will pay interest on
Junior Subordinated Notes, subject to such surrender, where applicable, 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 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 the applicable Prospectus Supplement states otherwise, the Trustee
will act as paying agent for the Junior Subordinated Notes, and the principal
corporate trust office of the 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 exceptions, with respect
     to any series of Junior Subordinated Notes, such a discharge being
     called a "Defeasance" in this Prospectus; and


                                       18
<PAGE>

  .  released from its obligations under certain restrictive covenants
     especially established with respect to a series of Junior Subordinated
     Notes, such a release being called a "Covenant Defeasance" in this
     Prospectus.

  Duke Energy must satisfy certain conditions to effect a Defeasance. Those
conditions include the irrevocable deposit with the 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 such 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 law, a Defeasance would be
treated as an exchange of the relevant Junior Subordinated Notes in which
holders of 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 what would be includible
absent 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.

  The Junior Subordinated Notes 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;


                                       19
<PAGE>

  .  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
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, 1999, Duke Energy's Senior
Indebtedness totaled approximately $4,100,000,000.

Concerning the Trustee

  The Chase Manhattan Bank is the Trustee under the Subordinated Indenture. The
Chase Manhattan Bank is also the Trustee under Duke Energy's First and
Refunding Mortgage and its Senior Indenture. Duke Energy and certain of its
affiliates maintain deposit accounts and banking relationships with The Chase
Manhattan Bank. The Chase Manhattan Bank serves as trustee under other
indentures pursuant to which securities of Duke Energy and affiliates of Duke
Energy are outstanding.

                              PLAN OF DISTRIBUTION

  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
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.


                                       20
<PAGE>

  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 Preferred Securities, those
underwriters will acquire the 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 the applicable Prospectus Supplement states otherwise, the obligations
of any underwriter to purchase the Preferred Securities will be subject to
conditions, and the underwriter will be obligated to purchase all the Preferred
Securities offered, except that in some cases involving a default by an
underwriter, less than all of the Preferred Securities offered may be
purchased. If 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 the Prospectus Supplement states otherwise,
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 Energy.

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