                           [   ] Preferred Securities
                         Duke Energy Capital Trust [  ]
                          % Trust Preferred Securities
                (Liquidation amount $   per Preferred Security)

wishes, Duke Energy may begin an extension period, during which distributions
will be deferred for up to consecutive quarters, but not beyond the maturity
date of the Series Junior Subordinated Notes. During an extension period,
deferred distributions on the Preferred Securities will accumulate additional
distributions at a yearly rate of %, to the extent legally permitted.
 
  When the Series   Junior Subordinated Notes mature or when Duke Energy
redeems or repays any Series   Junior Subordinated Notes, the Trust will
redeem a related amount of Preferred Securities. The maturity date of the
Series   Junior Subordinated Notes is          ,     . Duke Energy may redeem
the Series   Junior Subordinated Notes (1) at any time on or after          ,
    , in whole or in part, or (2) at any time during the 90 days after the
occurrence of certain tax or regulatory developments, in whole but not in part.
The redemption price of the Preferred Securities will equal their liquidation
amount plus any accumulated and unpaid distributions. Duke Energy may cause the
Trust to distribute to the holders of Preferred Securities an equivalent amount
of Series   Junior Subordinated Notes at any time in exchange for the Preferred
Securities.
 
  You should carefully read "Risk Factors" beginning on page S-8 to read about
specific risks associated with the Preferred Securities, as well as the other

                               Subordinated Notes due        ,   . Duke Energy
                               will issue the Series  Junior Subordinated Notes
                               under its Subordinated Indenture. The Trust will
                               use the proceeds from the sale of the Preferred
                               Securities to purchase Series   Junior
                               Subordinated Notes. The Series   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   Junior Subordinated
                               Notes by extending the interest payment period
                               on the Series   Junior Subordinated Notes, at
                               any time and as often as it wishes, for up to
                               consecutive quarters (each, an "extension
                               period") but not beyond the maturity date of the
                               Series   Junior Subordinated Notes. If Duke
                               Energy defers payments of interest on the Series
                                 Junior Subordinated Notes, distributions on
                               the Preferred Securities will also be deferred.
 
                               Deferred interest will bear interest at a yearly
                               rate of  %, 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   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

                               priority with or subordinate to the Series
                               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   Junior    
                               Subordinated Notes at maturity or upon         
                               redemption.                                     
 
                               Duke Energy may redeem the Series   Junior
                               Subordinated Notes at any time, in whole or in
                               part, on or after          ,       . Duke
                               Energy may also redeem the Series   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   Junior Subordinated Notes, each holder
                               of a Preferred Security will be entitled to
                               receive a liquidation amount of $   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   Junior Subordinated Notes, (2)      
                               interest payable on the Series   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

                               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   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
Junior Subordinated Notes...  The Series   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
                               "Description of the Junior Subordinated Notes--
                               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.....................  Duke Energy intends to list the Preferred         
                               Securities on the New York Stock Exchange under

                               Preferred Securities on the New York Stock       
                               Exchange will begin within 30 days after the

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
                               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
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   Junior Subordinated Notes. If
Duke Energy fails to make timely payments on the Series   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   Junior Subordinated Notes
 
  Duke Energy's obligations under the Series   Junior Subordinated Notes are
subordinate and junior in right of payment to all of Duke Energy's Senior
Indebtedness. As of          ,     , Duke Energy's Senior Indebtedness totaled
approximately $      . 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   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
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.

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   Junior Subordinated Notes for up to
consecutive quarters, but not beyond the maturity date of the Series   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   Junior
Subordinated Notes at a yearly rate of    %, 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   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   Junior
Subordinated Notes, will not receive cash related to that income if the holder
disposes of the Preferred Securities, or the Series   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    Junior Subordinated
Notes in whole during the 90 days after the occurrence of a Special Event. If
Duke Energy redeems the Series   Junior Subordinated Notes after the occurrence
of a Special Event, the Trust will redeem the Preferred Securities.
 
Distribution of Series   Junior Subordinated Notes upon Termination of Trust
 
  Duke Energy will have the right to terminate the Trust at any time and cause
the Series   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   Junior
Subordinated Notes if a termination and liquidation of the Trust occurs and
Series   Junior Subordinated Notes are distributed in exchange for Preferred
Securities. The Series   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   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   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   Junior Subordinated Notes through the date of disposition and to
add that amount to the holder's adjusted tax basis in the related Series
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   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 [   ]
 
  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   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    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   Junior
Subordinated Notes occurs.
 
  The Property Trustee will hold legal title to the Series   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   Junior Subordinated Notes.
 
  The Series   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   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   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   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   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
  % 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           ,     , 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   Junior
Subordinated Notes by extending the interest payment period from time to time
on the Series   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   Junior Subordinated
Notes will bear interest at a yearly rate of    %, 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   Junior Subordinated Notes.
 
Redemption
 
  The Trust will redeem the Preferred Securities when Duke Energy repays the
Series   Junior Subordinated Notes at maturity or upon redemption. The Series
Junior Subordinated Notes will mature on          ,     . Duke Energy may
redeem the Series   Junior Subordinated Notes, in whole or in part, at its
option at any time on or after         ,    . Duke Energy may also redeem the
Series   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   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   Junior Subordinated Notes
only in whole if a partial redemption of the Series   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 $   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   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   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   Junior Subordinated
    Notes;
 
  . interest payable on the Series   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.

Distribution of Series   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   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   Junior Subordinated Notes are distributed to the holders of the
Preferred Securities, Duke Energy will use its best efforts to have the Series
  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   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   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
    Junior Subordinated Notes. Those Series   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   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   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.
 
Book-Entry Issuance--The Depository Trust Company
 
  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 $     or whole multiples
of $    . 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           ,     , 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   Junior Subordinated Notes to the holders of the
    Trust Securities in liquidation of the Trust; or
 
  . if Duke Energy repays all the Series   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   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   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 $     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   Junior Subordinated Notes, however,
the Preferred Securities will have a preference over the Common Securities with
respect to the payment.

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   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 occurs and is continuing:
 
  . the holders of Preferred Securities will rely on the Property Trustee, as
    the holder of the Series   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   Junior Subordinated Notes.
 
  If the Property Trustee fails to enforce its rights under the Series   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   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   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   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   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   Junior Subordinated Notes.
 
Voting Rights
 
  So long as the Property Trustee holds any Series   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   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   Junior Subordinated Notes will be due and payable; or
 
  . consent to any amendment, modification or termination of the Subordinated
    Indenture or the Series   Junior Subordinated Notes, if that consent is
    required, or to any other action, as the holder of the Series   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   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.

  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   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   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.

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   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   JUNIOR SUBORDINATED NOTES
 
  The following description of the Series   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   Junior Subordinated Notes as a series of
Subordinated Notes under the Subordinated Indenture. The Series   Junior
Subordinated Notes will be limited in principal amount to $          , which is
the liquidation amount of the Trust Securities.
 
  The Series   Junior Subordinated Notes will mature and become due and
payable, together with any accrued and unpaid interest, including any
Additional Interest, on          ,     .
 
  The Series   Junior Subordinated Notes will rank equal in priority with any
other series of Junior Subordinated Notes issued under the Subordinated
Indenture.
 
  The Series   Junior Subordinated Notes are not subject to any sinking fund
provision.
 
Optional Redemption
 
  Duke Energy will have the right to redeem the Series   Junior Subordinated
Notes:
 
  . from time to time, in whole or in part, on or after          ,     ; 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   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   Junior Subordinated Notes would cause
the Preferred Securities to be delisted, Duke Energy will be required to redeem
all of the Series   Junior Subordinated Notes.
 
Interest
 
  The Series   Junior Subordinated Notes will bear interest at a yearly rate of
 % from the original issue date. Interest on the Series   Junior Subordinated
Notes will be payable quarterly in arrears on March 31, June 30, September 30
and December 31 of each year, commencing on         ,     , unless the
applicable interest period is extended. Interest will be payable to the person
or persons in whose name the Series 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   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   Junior Subordinated Notes by extending the
interest payment period for up to    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   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   Junior
Subordinated Notes.
 
  Duke Energy will notify the holder or holders of the Series   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    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   Junior Subordinated Notes, accruing at a yearly rate of    %
    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   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   Junior Subordinated Notes and the extension is
    continuing; or
 
  . if an event of default under the Subordinated Indenture with respect to
    the Series   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   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   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   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   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   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   Junior Subordinated Notes will be issuable in registered form
without coupons. The Series   Junior Subordinated Notes will be issuable in
denominations of $     and multiples of $    .
 
Defeasance
 
  The Series   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   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.

<PAGE>
 
                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
            THE SERIES   JUNIOR SUBORDINATED NOTES AND THE GUARANTEE
 
  As long as Duke Energy makes interest and other payments on the Series
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   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
    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   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   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   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   Junior Subordinated Notes.
 
  If the Property Trustee fails to enforce its rights under the Series   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   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   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   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   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    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   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   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    Junior Subordinated
Notes provide that no payments may be made in respect of the Series   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   Junior Subordinated Notes held by the Trust. Accordingly, a
holder will include in income the holder's share of the income from the Series
   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   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   Junior Subordinated Notes would at that
time be treated as issued with original issue discount and all the stated
interest payments on the Series   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

  Since the proceeds of the sale of the Preferred Securities will be used to
purchase Series   Junior Subordinated Notes, the Underwriting Agreement
provides that Duke Energy will pay as compensation to the Underwriters $
per Preferred Security for the accounts of the several Underwriters, or $
in the aggregate.
 
  The Underwriters have advised Duke Energy and the Trust that they propose to
offer the Preferred Securities:
 
  . in part directly to the public at the initial public offering price that
    is stated on the cover page of this Prospectus Supplement; and
 
  . in part to certain securities dealers at that price less a concession not
    in excess of $      per Preferred Security.
 
The Underwriters may allow, and those dealers may reallow, a concession not in
excess of $     per Preferred Security to certain other dealers. The
Representatives may vary the offering price and other selling terms from time
to time after the Preferred Securities are released for sale to the public.
 
  The Preferred Securities are expected to be 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
a 30-day period after the initial delivery of the Preferred Securities. The
Representatives 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 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,
 
                                      S-33
<PAGE>
 
the Underwriters will undertake to sell lots of 100 or more Preferred
Securities to a minimum of 400 beneficial holders.
 
  The Underwriters may purchase and sell the Preferred Securities in the open
market in connection with the offering. Those transactions may include over-
allotment and stabilizing transactions and purchases to cover syndicate short
positions created in connection with the offering. Stabilizing transactions
consist of certain bids or purchases for the purpose of preventing or retarding
a decline in the market price of the Preferred Securities. Syndicate short
positions involve the sale by the Underwriters of a greater number of Preferred
Securities than they are required to purchase from the Trust in the offering.
The Underwriters also may impose a penalty bid, by which selling concessions
allowed to syndicate members or other broker-dealers with respect to the
Preferred Securities sold for their account in the offering may be reclaimed by
the syndicate if those Preferred Securities are repurchased by the syndicate in
stabilizing or covering transactions. These activities may stabilize, maintain
or otherwise affect the market price of the Preferred Securities, which may be
higher than the price that might otherwise prevail in the open market. These
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the New York Stock Exchange, in the over-the-counter market
or otherwise.
 
  Duke Energy and the Trust have agreed to indemnify the Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.
 
  Duke Energy estimates that it will spend approximately $          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   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.            , who is Duke Energy's            , will pass

                                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.

                              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.

Item 17. Undertakings.
 
(a) Undertaking related to Rule 415 offering:
 
The undersigned registrants hereby undertake:
 
(1) To file, during any period in which offers or sales are being made, a post-
effective amendment to this registration statement:
 
(i) To include any prospectus required by Section 10(a)(3) of the Securities
Act of 1933 (the "Act");
 
(ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement;
notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;
 
(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;
 
Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, S-8 or F-3 and the information required
to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed by the registrants pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by reference
in the registration statement.
 
                                      II-3
<PAGE>
 
(2) That, for the purpose of determining any liability under the Act, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
(b) Undertaking related to filings incorporating subsequent Securities Exchange
Act of 1934 documents by reference:
 
The undersigned registrants hereby undertake that, for purposes of determining
any liability under the Act, each filing of Duke Energy Corporation's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange
Act of 1934 that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
(c) Undertaking related to acceleration of effectiveness:
 
Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of each undersigned
registrant pursuant to the indemnification provisions described in Item 15
above or in contractual arrangements pursuant thereto, or otherwise, each
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by each
undersigned registrant of expenses incurred or paid by a director, officer or
controlling person of each registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, each registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
(d) The undersigned registrants hereby undertake that:
 
(1) For purposes of determining any liability under the Act, the information
omitted from the form of prospectus filed as part of this registration
statement in reliance upon Rule 430A and contained in a form of prospectus
filed by the registrants pursuant to Rule 424(b)(1) or 497(h) under the Act
shall be deemed to be part of this registration statement as of the time it was
declared effective.
 
(2) For the purpose of determining any liability under the Act, each post-
effective amendment that contains a form of prospectus shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  be deemed to refer to and include the documents incorporated by reference
  therein, as of the date of such Preliminary Prospectus or Prospectus, as
  the case may be; any reference to any amendment or supplement to any

  and include any annual report of the Corporation filed pursuant to Section
  13(a) or 15(d) of the 1934 Act after the effective date of the Registration
  Statement that is incorporated by reference in the Registration Statement).

  time they were filed with the Commission, conformed in all material
  respects to the requirements of the 1934 Act and the rules and regulations

  untrue statement of a material fact or omit to state a material fact
  required to be stated therein or necessary to make the statements therein
  not misleading, and any documents deemed to be incorporated by reference in

  Regulations, and will not contain an untrue statement of a material fact or
  omit to state a material fact required to be stated therein or necessary to
  make the statements therein, in the light of the circumstances under which
  they are made, not misleading, except that the Corporation makes no
  warranty or representation to the Underwriters with respect to any
  statements or omissions made in reliance upon and in conformity with
  written information furnished to the Trust or the Corporation by any
  Underwriter through you specifically for use therein.

  provisions of this Agreement and the consummation of the transactions
  herein contemplated will not conflict with or result in a breach or
  violation of any of the terms or provisions of, or constitute a default

may become obligated to purchase pursuant to the provisions of Section 8
hereof.
 
  As compensation to the Underwriters for their commitments hereunder, and in
view of the fact that the proceeds of the sale of the Preferred Securities will
be used by the Trust to purchase the Notes of the Corporation, the Corporation

  The Preferred Securities to be purchased by the Underwriters hereunder will
be represented by a global certificate or certificates in book-entry form which
will be deposited by or on behalf of the Trust with The Depository Trust
Company ("DTC") or its designated custodian and registered in the name of Cede
& Co., as nominee of DTC. The Trust will deliver the Preferred Securities to
               , for the respective accounts of the Underwriters, against
payment by or on behalf of such Underwriters of the purchase price therefor by
wire transfer of immediately available funds to the Trust, by causing DTC to
credit the Preferred Securities to the account of                    , at DTC.
The time and date of such delivery and payment (the "Closing Date") shall be

accordance with the provisions of Section 8), or at such other time and date as
you, the Trust and the Corporation may agree upon in writing, at the office of
Dewey Ballantine LLP, 1301 Avenue of the Americas, New York, New York 10019, or

understood that each Underwriter has authorized                    , for its
account, to accept delivery of, receipt for, and make payment of the purchase
price, for the Preferred Securities which it has agreed to purchase.
 
  At the Closing Date, the Corporation will pay, or cause to be paid, the
compensation payable to the Underwriters under this Section 3 by wire transfer
of immediately available funds to                     , as representative of
and on behalf of the Underwriters.

  as soon as possible its lifting, if issued.

    (b) If at any time when a prospectus relating to the Preferred
  Securities, the Guarantee or the Notes is required to be delivered under
  the 1933 Act, any event occurs as a result of which the Prospectus as then
  amended or supplemented would include an untrue statement of a material
  fact, or omit to state any material fact necessary to make the statements
  therein, in the light of the circumstances under which they were made, not
  misleading, or if it is necessary at any time to amend the Prospectus to
  comply with the 1933 Act, the Trust and the Corporation promptly will
  prepare and file with the Commission an amendment, supplement or an
  appropriate document pursuant to Section 13 or 14 of the 1934 Act which
  will correct such statement or omission or which will effect such
  compliance.
 
    (c) The Trust and the Corporation, during the period when a prospectus
  relating to the Preferred Securities, the Guarantee or the Notes is
  required to be delivered under the 1933 Act, will file promptly all

  include all exhibits other than those incorporated by reference), the
  Prospectus, and all amendments and supplements to such documents, in each
  case as soon as available and in such quantities as you reasonably request.
 
    (f) The Trust and the Corporation will arrange or cooperate in
  arrangements for the qualification of the Preferred Securities, and to the
  extent required or advisable, the Guarantee and the Notes for sale under
  the laws of such jurisdictions as you designate and will continue such
  qualifications in effect so long as required for the distribution;
  provided, however, that neither the Trust nor the Corporation shall be
  required to qualify as a foreign corporation or to file any general
  consents to service of process under the laws of any state where it is not
  now so subject.

Corporation of their obligations hereunder and to the following additional
conditions precedent:
 
    (a) Prior to the Closing Date, no stop order suspending the effectiveness

      (ii) Each of the Corporation and the Principal Subsidiaries is duly
    qualified to do business in each jurisdiction in which the ownership or
    leasing of its property or the conduct of its business requires such
    qualification, except where the failure to so qualify, considering all
    such cases in the aggregate, does not have a material adverse effect on
    the business, properties, financial position or results of operations
    of the Corporation and its subsidiaries taken as a whole.
 
      (iii) The Trust Agreement has been duly authorized, executed and
    delivered by the Corporation, and, assuming due authorization,
    execution and delivery thereof by The Chase Manhattan Bank, as Property
    Trustee, constitutes a valid and legally binding instrument of
 
                                       6
<PAGE>
 
    the Corporation, enforceable against the Corporation in accordance with
    its terms, subject to the qualifications that the enforceability of the
    Corporation's obligations under the Trust Agreement may be limited by
    bankruptcy, insolvency, reorganization, moratorium and other similar
    laws relating to or affecting creditors' rights generally, and by
    general principles of equity (regardless of whether such enforceability
    is considered in a proceeding in equity or at law).
 
      (iv) The Guarantee Agreement has been duly authorized, executed and
    delivered by the Corporation, and, assuming due authorization,
    execution and delivery thereof by The Chase Manhattan Bank, as
    Guarantee Trustee, constitutes a valid and legally binding instrument
    of the Corporation, enforceable against the Corporation in accordance
    with its terms, subject to the qualifications that the enforceability
    of the Corporation's obligations under the Guarantee Agreement may be
    limited by bankruptcy, insolvency, reorganization, moratorium and other

    by general principles of equity (regardless of whether such
    enforceability is considered in a proceeding in equity or at law).
 
      (v) The Indenture has been duly authorized, executed and delivered by
    the Corporation and, assuming the due authorization, execution and
    delivery thereof by The Chase Manhattan Bank, as Indenture Trustee,
    constitutes a valid and legally binding instrument of the Corporation,
    enforceable against the Corporation in accordance with its terms,
    subject to the qualifications that the enforceability of the
    Corporation's obligations under the Indenture may be limited by
    bankruptcy, insolvency, reorganization, moratorium and other similar

    general principles of equity (regardless of whether such enforceability
    is considered in a proceeding in equity or at law).
 
      (vi) The Notes have been duly authorized and executed by the
    Corporation and, when authenticated by The Chase Manhattan Bank, as
    Indenture Trustee, in the manner provided in the Indenture and
    delivered against payment therefor, will constitute valid and legally
    binding obligations of the Corporation, enforceable against the
    Corporation in accordance with their terms, subject to the
    qualifications that the enforceability of the Corporation's obligations
    under the Notes may be limited by bankruptcy, insolvency,
    reorganization, moratorium and other similar laws relating to or
    affecting creditors' rights generally and by general principles of
    equity (regardless of whether such enforceability is considered in a
    proceeding in equity or at law).
 
      (vii) The Registration Statement has become effective under the 1933
    Act, and, to the best of the knowledge of such counsel, no stop order
    suspending the effectiveness of the Registration Statement has been
    issued and no proceedings for that purpose have been instituted or are
    pending or threatened under the 1933 Act.
 
      (viii) This Agreement has been duly authorized, executed and
    delivered by the Corporation.
 
      (ix) The North Carolina Utilities Commission and The Public Service
    Commission of South Carolina have issued appropriate orders with
    respect to the issuance of the Notes and the Guarantee, and, to the
    best of the knowledge of such counsel, such orders are still in effect;
    the issuance of the Notes and the Guarantee is in conformity with the
    terms of
 
                                       7
<PAGE>
 
    such orders; and no other authorization, approval or consent of any
    other governmental body is legally required for the issuance of the
    Notes and the Guarantee.
 
      (x) The performance by the Corporation of this Agreement and the
    Corporation Agreements will not contravene any of the provisions of the
    Restated Articles of Incorporation or By-Laws of the Corporation.
 
      (xi) The descriptions in the Registration Statement and Prospectus of
    legal or governmental proceedings are accurate and fairly present the
    information required to be shown and such counsel does not know of any
    other legal or governmental proceedings required to be described in the
    Registration Statement or Prospectus which are not described as
    required.
 
  Such counsel shall also state that nothing has come to her attention that has
caused her to believe that the Registration Statement as of the date of
effectiveness under the 1933 Act and the Prospectus as of the date it was filed
with, or transmitted for filing to, the Commission, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
that the Prospectus as of the date it was filed with, or transmitted for filing
to, the Commission and at the Closing Date, contained or contains any untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. Such counsel may also
state that, except as otherwise expressly provided in such opinion, she does
not assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement and the Prospectus and does
not express any opinion or belief as to the financial statements or other
financial data contained in or incorporated by reference into the Registration
Statement and the Prospectus or as to the statement of the eligibility and
qualification of each of the Indenture Trustee, Property Trustee and Guarantee
Trustee.
 
  In rendering the foregoing opinion, such counsel may state that she expresses
no opinion as to the laws of any jurisdiction other than North Carolina and may
rely on the opinion of Austin, Lewis & Rogers of Columbia, South Carolina as to
matters of South Carolina law. Such counsel may also state that she has relied
as to certain factual matters on information obtained from public officials,
officers of the Corporation and other sources believed by her to be
responsible.
 
   (e) You shall have received an opinion or opinions of Dewey Ballantine LLP,
counsel to the Corporation, dated the Closing Date, with respect to the matters
set forth in (i) and (iii) through (x) of Section 6(d) and to the further
effect that:
 
      (i) Each of the Principal Subsidiaries has been duly incorporated and
    is validly existing as a corporation in good standing under the laws of
    its jurisdiction of incorporation, with power and authority (corporate
    and other) to own its properties and conduct its business as described
    in the Prospectus.
 
      (ii) The Indenture is duly qualified under the Trust Indenture Act of
    1939.
 
      (iii) The Registration Statement as of the date of effectiveness
    under the 1933 Act and the Prospectus as of the date it was filed with,
    or transmitted for filing to, the Commission (in each case, other than
    the financial statements and other financial information included
    therein, as to which no opinion need be rendered) complied as to form
    in all material respects with the requirements of the 1933 Act and the
    1933 Act Regulations; the
 
                                       8
<PAGE>
 
    Corporation Agreements have each been qualified under the Trust
    Indenture Act of 1939; and nothing has come to their attention that
    would lead them to believe that the Registration Statement as of the
    date of effectiveness under the 1933 Act (or if an amendment to such
    Registration Statement or an annual report on Form 10-K has been filed
    by the Corporation with the Commission subsequent to the effectiveness
    of the Registration Statement, then at the time of the most recent such
    filing) contained an untrue statement of a material fact or omitted to
    state a material fact required to be stated therein or necessary to
    make the statements therein not misleading or that the Prospectus as of
    the date it was filed with, or transmitted for filing to, the
    Commission and at the Closing Date contained or contains an untrue
    statement of a material fact or omitted or omits to state a material
    fact necessary in order to make the statements therein, in the light of
    the circumstances under which they were made, not misleading.
 
      (iv) The statements made in the Prospectus under the captions
    "Description of the Preferred Securities," "Description of the
    Guarantees," "Description of the Series   Junior Subordinated Notes"
    and "Description of the Junior Subordinated Notes," insofar as they
    purport to constitute summaries of the terms of the Preferred
    Securities, the Guarantee and the Notes, and the statements as to
    matters of law and legal conclusions contained in the Prospectus under
    the caption "Material Federal Income Tax Considerations," are correct
    in all material respects.
 
  In rendering the foregoing opinion or opinions, Dewey Ballantine LLP may
state that such opinion or opinions are limited to the Federal laws of the
United States, the laws of the State of New York and the General Corporation
Law of the State of Delaware, and that they are relying on the opinion of Ellen
T. Ruff, Esq. as to matters of North Carolina law and on the opinion of Austin,
Lewis & Rogers of Columbia, South Carolina as to matters of South Carolina law.
In addition, such counsel may state that they have relied as to certain factual
matters on information obtained from public officials, officers of the
Corporation and other sources believed by them to be responsible and that the
signatures on all documents examined by them are genuine, assumptions which
such counsel have not independently verified.
 
   (f) You shall have received the opinion of Richards, Layton & Finger, P.A.,
special Delaware counsel to the Trust and the Corporation, dated the Closing
Date, to the effect that:
 
      (i) The Trust has been duly created and is validly existing in good
    standing as a business trust under the Business Trust Act of the State

    creation and valid existence of the Trust as a business trust have been

    Preferred Securities and the Common Securities.
 
                                       9
<PAGE>
 
      (iv) Under the Delaware Business Trust Act and the Trust Agreement,
    the execution and delivery by the Trust of this Agreement and the

    Trust Agreement have been duly authorized by all necessary business
    trust action on the part of the Trust.
 
      (v) The Trust Agreement constitutes a valid and binding obligation of
    the Corporation and the trustees named therein, enforceable against the
    Corporation and the trustees named therein, in accordance with its
    terms, subject, as to enforcement, to the effect upon the Trust
    Agreement of (a) bankruptcy, insolvency, moratorium, receivership,
    liquidation, fraudulent conveyance or transfer, reorganization and
    other similar laws relating to or affecting the remedies and rights of
    creditors generally, (b) principles of equity, including applicable law
    relating to fiduciary duties (regardless of whether considered or
    applied in a proceeding in equity or at law) and (c) the effect of
    applicable public policy on the enforceability of provisions relating
    to indemnification or contribution.
 
      (vi) The Preferred Securities have been duly authorized by the Trust
    Agreement and are duly and validly issued and, subject to the
    qualifications set forth herein, fully paid and non-assessable
    preferred undivided beneficial interests in the assets of the Trust;
    the Holders of the Preferred Securities, as beneficial owners of the
    Trust (the "Securityholders"), are entitled to the same limitation of
    personal liability extended to stockholders of private corporations for
    profit organized under the General Corporation Law of the State of
    Delaware; provided, however, that such counsel may note that the
    Securityholders may be obligated, pursuant to the Trust Agreement, to
    (a) provide indemnity and/or security in connection with and pay a sum
    sufficient to cover any taxes or governmental charges arising from
    transfers or exchanges of Preferred Securities certificates and the
    issuance of replacement Preferred Securities certificates and (b)
    provide security and/or indemnity in connection with requests of or
    directions to the Property Trustee (as defined in the Trust Agreement)
    to exercise its rights and powers under the Trust Agreement; and under
    the Delaware Business Trust Act and the Trust Agreement, the issuance
    of the Preferred Securities is not subject to preemptive or other
    similar rights.
 
      (vii) The Common Securities have been duly authorized by the Trust
    Agreement and are duly and validly issued and fully paid common
    undivided beneficial interests in the assets of the Trust; and under
    the Delaware Business Trust Act and the Trust Agreement, the issuance
    of the Common Securities is not subject to preemptive or other similar
    rights.
 
      (viii) The issuance and sale by the Trust of the Preferred Securities
    and the Common Securities, the execution, delivery and performance by
    the Trust of this Agreement, the performance by the Trust of the Trust
    Agreement, the consummation by the Trust of the transactions
    contemplated herein and therein and the compliance by the Trust with
    its obligations hereunder do not violate (a) any of the provisions of
    the Certificate of Trust of the Trust or the Trust Agreement or (b) any
    applicable Delaware law or Delaware administrative regulation.
 
      (ix) Assuming that the Trust derives no income from or connected with
    sources within the State of Delaware and has no assets, activities
    (other than having a Delaware trustee as required by the Delaware
    Business Trust Act and the filing of documents with the Secretary
 
                                       10
<PAGE>
 
    of State of the State of Delaware) or employees in the State of
    Delaware, no authorization, approval, consent or order of any Delaware
    court or Delaware governmental authority or Delaware agency is required
    to be obtained by the Trust solely as a result of the issuance and sale
    of the Preferred Securities, the consummation by the Trust of the
    transactions contemplated in this Agreement and the Trust Agreement or
    the compliance by the Trust of its obligations hereunder and
    thereunder.
 
      (x) Assuming that the Trust derives no income from or connected with
    sources within the State of Delaware and has no assets, activities
    (other than having a Delaware trustee as required by the Delaware
    Business Trust Act and the filing of documents with the Secretary of
    State of the State of Delaware) or employees in the State of Delaware,
    and assuming that the Trust is treated as a grantor trust for federal
    income tax purposes, the Securityholders (other than those holders of
    the Preferred Securities who reside or are domiciled in the State of
    Delaware) will have no liability for income taxes imposed by the State
    of Delaware solely as a result of their participation in the Trust, and
    the Trust will not be liable for any income tax imposed by the State of
    Delaware.
 
    In rendering the opinion expressed in this paragraph (f), such counsel
  need express no opinion concerning the securities laws of the State of
  Delaware.

  in the manner contemplated in the Prospectus. In such event there shall be
  no liability on the part of any party to any other party except as

  7. Indemnification. (a) The Trust and the Corporation, jointly and severally,
agree to indemnify and hold harmless each Underwriter and each person, if any,
who controls any Underwriter within the meaning of Section 15 of the 1933 Act,
as follows:
 
    (i) against any and all loss, liability, claim, damage and expense
  whatsoever arising out of any untrue statement or alleged untrue statement
  of a material fact contained in the Registration Statement (or any
  amendment thereto), or the omission or alleged omission therefrom of a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading or arising out of any untrue statement or
  alleged untrue statement of a material fact contained in any Preliminary
  Prospectus, the prospectus constituting a part of the Registration
  Statement in the form in which it became effective or the Prospectus (or
  any amendment or supplement thereto) or the omission or alleged omission
  therefrom of a material fact necessary in order to make the statements
  therein, in the light of the circumstances under which they were made, not
  misleading, unless such statement or omission or such alleged statement or
  omission was made in reliance upon and in conformity with written
  information furnished to the Trust or the Corporation by any Underwriter
  through you expressly for use in the Registration Statement (or any
  amendment thereto) or such Preliminary Prospectus, such prospectus, or the
  Prospectus (or any amendment or supplement thereto);
 
    (ii) against any and all loss, liability, claim, damage and expense
  whatsoever to the extent of the aggregate amount paid in settlement of any
  litigation, commenced or threatened, or of any claim whatsoever based upon
  any such untrue statement or omission or any such alleged untrue statement
  or omission, if such settlement is effected with the written consent of the
  Trust and the Corporation; and
 
                                       12
<PAGE>
 
    (iii) against any and all expense whatsoever reasonably incurred in
  investigating, preparing or defending against any litigation, commenced or
  threatened, or any claim whatsoever based upon any such untrue statement or
  omission, or any such alleged untrue statement or omission, to the extent
  that any such expense is not paid under (i) or (ii) above.
 
  In no case shall the Trust or the Corporation be liable under this indemnity
agreement with respect to any claim made against any Underwriter or any such
controlling person unless the Trust and the Corporation shall be notified in
writing of the nature of the claim within a reasonable time after the assertion
thereof, but failure so to notify the Trust or the Corporation shall not
relieve either of them from any liability which either of them may have
otherwise than on account of this indemnity agreement. The Trust and the
Corporation shall be entitled to participate at their own expense in the
defense, or, if they so elect, within a reasonable time after receipt of such
notice, to assume the defense of any suit brought to enforce any such claim,
but if they so elect to assume the defense, such defense shall be conducted by
counsel chosen by them and approved by the Underwriter or Underwriters or
controlling person or persons, or defendant or defendants in any suit so
brought, which approval shall not be unreasonably withheld. In any such suit,
any Underwriter or any such controlling person shall have the right to employ
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Underwriter or such controlling person unless (i) the Trust and
the Corporation and such Underwriter shall have mutually agreed to the
employment of such counsel, or (ii) the named parties to any such action
(including any impleaded parties) include both such Underwriter or such
controlling person and the Trust or the Corporation and such Underwriter or
such controlling person shall have been advised by such counsel that a conflict
of interest between the Trust or the Corporation and such Underwriter or such
controlling person may arise and for this reason it is not desirable for the
same counsel to represent both the indemnifying party and also the indemnified
party (it being understood, however, that the Trust and the Corporation shall
not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys for all such Underwriters
and all such controlling persons, which firm shall be designated in writing by
you). The Trust and the Corporation agree to notify you within a reasonable
time of the assertion of any claim against them, any of their officers,
directors or trustees or any person who controls the Trust or the Corporation
within the meaning of Section 15 of the 1933 Act, in connection with the sale
of the Preferred Securities.
 
  (b) Each Underwriter severally agrees that it will indemnify and hold
harmless the Trust and the Corporation, their directors, trustees,
representatives and each of the officers of the Corporation who signed the
Registration Statement and each person, if any, who controls them within the
meaning of Section 15 of the 1933 Act to the same extent as the indemnity
contained in subsection (a) of this Section, but only with respect to
statements or omissions made in the Registration Statement (or any amendment
thereto) or any Preliminary Prospectus, such prospectus or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Trust or the Corporation by such
Underwriter through you expressly for use in the Registration Statement (or any
amendment thereto), such Preliminary Prospectus, such prospectus or the
Prospectus (or any amendment or supplement thereto). In case any action shall
be brought against the Trust or the Corporation or any person so indemnified
based on the Registration Statement (or
 
                                       13
<PAGE>
 
any amendment thereto) or such Preliminary Prospectus, such prospectus or the
Prospectus (or any amendment or supplement thereto) and in respect of which
indemnity may be sought against any Underwriter, such Underwriter shall have
the rights and duties given to the Trust and the Corporation, and the Trust and
the Corporation and each person so indemnified shall have the rights and duties
given to the Underwriters, by the provisions of subsection (a) of this Section.
 
  8. Default by One or More of the Underwriters. (a) If any Underwriter shall
default in its obligation to purchase the Preferred Securities which it has
agreed to purchase hereunder on the Closing Date, you may in your discretion
arrange for you or another party or other parties to purchase such Preferred
Securities on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such
Preferred Securities, then the Trust and the Corporation shall be entitled to a
further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Preferred Securities on such
terms. In the event that, within the respective prescribed periods, you notify
the Trust and the Corporation that you have so arranged for the purchase of
such Preferred Securities, or the Trust or the Corporation notifies you that it
has so arranged for the purchase of such Preferred Securities, you, the Trust
or the Corporation shall have the right to postpone such Closing Date for a
period of not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Registration Statement or the Prospectus, or
in any other documents or arrangements, and the Trust and the Corporation agree
to file promptly any amendments to the Registration Statement or the Prospectus
which may be required. The term "Underwriter" as used in this Agreement shall
include any person substituted under this Section with like effect as if such
person had originally been a party to this Agreement with respect to such
Preferred Securities.
 
  (b) If, after giving effect to any arrangements for the purchase of the
Preferred Securities of a defaulting Underwriter or Underwriters by you, the
Trust or the Corporation as provided in subsection (a) above, the aggregate
number of such Preferred Securities which remains unpurchased does not exceed
one-eleventh of the aggregate number of all the Preferred Securities to be
purchased at such Closing Date, then the Trust and the Corporation shall have
the right to require each non-defaulting Underwriter to purchase the number of
Preferred Securities which such Underwriter agreed to purchase hereunder at
such Closing Date and, in addition, to require each non-defaulting Underwriter
to purchase its pro rata share (based on the number of Preferred Securities
which such Underwriter agreed to purchase hereunder) of the Preferred
Securities of such defaulting Underwriter or Underwriters for which such
arrangements have not been made; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.
 
  (c) If, after giving effect to any arrangements for the purchase of the
Preferred Securities of a defaulting Underwriter or Underwriters by you, the
Trust or the Corporation as provided in subsection (a) above, the aggregate
number of such Preferred Securities which remains unpurchased exceeds one-
eleventh of the aggregate number of all the Preferred Securities to be
purchased at such Closing Date, or if the Trust or the Corporation shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Preferred Securities of a defaulting Underwriter or
Underwriters, then this Agreement shall thereupon terminate, without liability
on the part of any non-defaulting Underwriter, the Trust or the Corporation,
except for the expenses to be borne by the Corporation as provided in Section
5(g) hereof and the indemnity agreement in Section 7 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

and their respective successors, heirs and legal representatives any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision herein contained; this Agreement and all conditions and provisions
hereof being intended to be and being for the sole and exclusive benefit of the
parties hereto and their respective successors and said controlling persons,
officers, directors, trustees and representatives and their respective
successors, heirs and legal representatives, and for the benefit of no other

Underwriter shall be deemed to be a successor or assign by reason merely of
such purchase.
 
  14. Counterparts. This Agreement may be executed in two or more counterparts,
each of which shall be deemed to be an original, but all of which together
shall constitute one and the same instrument.
 
  15. Applicable Law. This Agreement shall be governed by, and construed in
accordance with, the internal laws of the State of New York.

  there shall have been presented to the Trustee proof satisfactory to it
  that such Series   Notes are held by a bona fide purchaser in whose hands
  such Series   Notes are valid obligations of the Corporation;
 
provided, however, that in determining, during any period in which any Series
Notes are owned by any Person other than the Corporation or any Affiliate
thereof, whether the Holders of the requisite principal amount of Outstanding
Series   Notes have given, made or taken any request, demand, authorization,
direction, notice, consent, waiver or other action hereunder as of any date,
Series   Notes owned, whether of record or beneficially, by the Corporation or
any Affiliate thereof (with the exception of the Securities Trust) shall be
disregarded and deemed not to be Outstanding. In determining whether the
Trustee shall be protected in relying upon such request, demand, authorization,
direction, notice, consent, waiver or other action, only Series   Notes that
the Trustee knows to be so owned by the Corporation or an Affiliate of the
Corporation (with the exception of the Securities Trust) in the above
circumstances shall be so disregarded. Series   Notes so owned that have been
pledged in good faith may be regarded as Outstanding if the pledgee establishes
to the satisfaction of the Trustee the pledgee's right so to act with respect
to such Series   Notes and that the pledgee is not the Corporation or any
Affiliate of the Corporation.

prospective change) in, laws (or any regulations thereunder) of the United
States or any political subdivision or taxing authority thereof or therein or
(b) any amendment to, or change in, an interpretation or application of such

provided for. Interest shall be paid quarterly in arrears on each Interest
Payment Date commencing       ,      to the Person in whose name the Series
Notes are registered on the Regular Record Date for such Interest Payment Date;
provided that interest payable at the Stated Maturity of principal or on a
Redemption Date as provided herein will be paid to the Person to whom principal
is payable. So long as an Extension Period is not occurring, any such interest
that is not so punctually paid or duly provided for will forthwith cease to be
payable to the Holders on such Regular Record Date and may either be paid to
the Person or Persons in whose name the Series   Notes are registered at the
close of business on a Special Record Date for the payment of such defaulted
interest to be fixed by the Trustee ("Special Record Date"), notice whereof
shall be given to Holders of the Series   Notes not less than ten (10) days
prior to such Special Record Date, or be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange, if
any, on which the Series   Notes may be listed, and upon such notice as may be
required by any such exchange, all as more fully provided in the Original

but excluding the respective Interest Payment Dates. Interest payments for the
Series   Notes shall be computed and paid on the basis of a 360-day year of
twelve 30-day months. In the event that any date on which interest is payable

that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on the date the payment was
originally payable.
 
  Payment of the principal and interest (including Additional Interest, if any)
on the Series   Notes shall be made at the office of the Paying Agent in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts, with any such payment
that is due at the Stated Maturity or at earlier redemption of any Series
Notes being made upon surrender of such Series   Notes to the Paying Agent.
Payments of interest (including interest on any Interest Payment Date) will be
made, subject to such surrender where applicable, at the option of the
Corporation, (i) by check mailed to the address of the Person entitled thereto
as such address shall appear in the Security Register or (ii) by wire transfer
at such place and to such account at a banking institution in the United States
as may be designated in writing to the Trustee at least sixteen (16) days prior
to the date for payment by the Person entitled thereto.
 
  The Corporation shall pay, as additional interest on the Series   Notes, when
due to the United States or any other taxing authority, the amounts set forth
in clause (i) of the definition of Additional Interest.
 
  Section 104. Deferral of Interest Payments. The Corporation has the right at
any time and from time to time to extend the interest payment period of the
Series   Notes for up to        (  ) consecutive quarters (each, an "Extension
Period"), during which Extension Period the Corporation shall have the right to
make partial payments of interest on any Interest Payment Date; provided,
however, that no such Extension Period may extend beyond the Stated Maturity.
Notwithstanding the foregoing, the Corporation has no right to extend its
obligation to pay such amounts as are defined in clause (i) of the definition
of Additional Interest. Prior to the termination of any such Extension Period,
the Corporation may further extend the interest payment period; provided that
such Extension Period, together with all such previous and further extensions
of that Extension Period, shall not exceed        (  ) consecutive quarters.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due, the
Corporation may select a new Extension Period, subject to the above limitations
and requirements.
 
  Upon the termination of any Extension Period, which termination shall be on
an Interest Payment Date, the Corporation shall pay all Deferred Interest on
the next succeeding Interest Payment Date to the Person or Persons in whose
name the Series   Notes are registered on the Regular Record Date for such
Interest Payment Date; provided that Deferred Interest payable at Stated
Maturity or on any Redemption Date will be paid to the Person or Persons to
whom principal is payable.
 
 
                                       5

  The Corporation shall give the Holder or Holders of the Series   Notes and
the Trustee notice, as provided in Sections 105 and 106, respectively, of the
Original Indenture, of its selection or extension of an Extension Period at
least one Business Day prior to the earlier of (i) the Regular Record Date
relating to the Interest Payment Date on which the Extension Period is to
commence or relating to the Interest Payment Date on which an Extension Period
that is being extended would otherwise terminate, or (ii) the date the
Corporation or the Securities Trust is required to give notice to the New York
Stock Exchange or other applicable self-regulatory organization of the record
date or the date such distributions are payable. The Corporation shall cause
the Securities Trust to give notice of the Corporation's selection of such
Extension Period to Holders of the Trust Securities. The month in which any
notice is given pursuant to the immediately preceding sentence of this Section
shall constitute the first month of the first quarter of the        (  )
consecutive quarters which comprise the maximum Extension Period.
 
  At any time any of the foregoing notices are given to the Trustee, the
Corporation shall give to the Paying Agent for the Series   Notes such
information as said Paying Agent shall reasonably require in order to fulfill
its tax reporting obligations with respect to such Series   Notes.
 
  Section 105. Denominations. The Series   Notes may be issued in denominations
of $   or any integral multiple thereof.
 
  Section 106. Global Securities. If the Series   Notes are distributed to
holders of the Trust Securities in liquidation of such holders' interests
therein, the Series   Notes will be issued in the form of one or more Global
Securities registered in the name of the Depositary (which shall be The
Depository Trust Company) or its nominee. Except under the limited
circumstances described below, Series   Notes represented by such Global
Security or Global Securities will not be exchangeable for, and will not
otherwise be issuable as, Series   Notes in definitive form. The Global
Securities described above may not be transferred except by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary
or another nominee of the Depositary or to a successor Depositary or its
nominee.
 
  Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series   Note shall be exchangeable, except for
another Global Security of like denomination and tenor to be registered in the
name of the Depositary or its nominee or to a successor Depositary or its
nominee or except as described below. The rights of Holders of such Global
Security shall be exercised only through the Depositary.
 
  A Global Security shall be exchangeable for Series   Notes registered in the
names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Corporation that it is unwilling or unable to continue
as a Depositary for such Global Security and no successor Depositary shall have
been appointed by the Corporation within 90 days of receipt by the Corporation
of such notification, or if at any time the Depositary ceases to be a clearing
agency registered under the Exchange Act at a time when the Depositary is
required to be so registered to act as such Depositary and no successor
Depositary shall have been appointed by the Corporation within 90 days after it
becomes aware of such cessation, or (ii) the Corporation in its sole discretion
determines that such Global Security shall be so exchangeable. Any Global
Security that is
 
                                       6
<PAGE>
 
exchangeable pursuant to the preceding sentence shall be exchangeable for
Series   Notes registered in such names as the Depositary shall direct.
 
  Section 107. Redemption. The Series   Notes shall be subject to redemption at
the option of the Corporation, in whole or in part, without premium or penalty,
at any time or from time to time on or after        ,     , at a Redemption
Price equal to 100% of the principal amount to be redeemed plus accrued but
unpaid interest (including any Additional Interest) to the Redemption Date;
provided, however, that, if a redemption in part shall result in the delisting
of the Preferred Securities, the Corporation may redeem the Series   Notes only
in whole. In addition, upon the occurrence of a Special Event, the Corporation
may, within ninety (90) days following the occurrence thereof and subject to
the terms and conditions of the Indenture, redeem the Series   Notes, in whole,
at a price equal to 100% of the principal amount to be redeemed plus any
accrued but unpaid interest (including Additional Interest, if any) to the
Redemption Date.
 
  In the event of redemption of the Series   Notes in part only, a new Series
Note or Notes for the unredeemed portion shall be issued in the name or names
of the Holders thereof upon the surrender thereof.
 
  The Series   Notes shall not have a sinking fund.
 
  Notice of redemption shall be given as provided in Section 1104 of the
Original Indenture. Notwithstanding the foregoing, no notice of redemption that
is given pursuant to such Section with respect to any Series   Notes shall,
while any Preferred Securities are outstanding, contain a condition that
provides that redemption of the Series   Notes, or the part thereof, specified
therein, shall be conditional upon receipt by the Trustee or the Paying Agent
for such Series   Notes, on or prior to the date fixed for such redemption, of
money sufficient to pay the principal of and any interest on such Series
Notes. Any notice provided to the Trustee under Section 1102 of the Original
Indenture shall also be provided by the Corporation to the Property Trustee;
provided that the Corporation shall provide notice pursuant to such Section
1102 on a date less than 45 days prior to the Redemption Date only if such
shorter notice is satisfactory to both the Trustee and the Property Trustee.
 
  Any redemption of less than all of the Series   Notes shall, with respect to
the principal thereof, be divisible by $  .
 
  Section 108. Additional Interest. Whenever there is mentioned in the
Indenture, in any context, the payment of the principal of, or any premium or
interest on, or in respect of, Securities of any series, such mention shall,
with respect to the Series   Notes, be deemed to include mention of the payment
of Additional Interest provided for by the terms of the Series   Notes to the
extent that, in such context, Additional Interest is, was or would be payable
in respect thereof pursuant to such terms, and express mention of the payment
of Additional Interest in any provisions of this     Supplemental Indenture
shall not be construed as excluding Additional Interest in those provisions of
the Original Indenture or this     Supplemental Indenture in which such express
mention is not made.
 
  If, subsequent to the date that a satisfaction and discharge or Defeasance is
effected pursuant to Section 401 or 1302, respectively, of the Original
Indenture, Additional Interest (for purposes of this
 
                                       7
<PAGE>
 
paragraph, as defined in clause (i) of the definition thereof) (in excess of
that established as of the date that such discharge or Defeasance is effected)
becomes payable in respect of the Series   Notes so discharged or defeased, the
Corporation shall irrevocably deposit or cause to be irrevocably deposited in
accordance with the provisions of Section 401 or 1304 of the Original
Indenture, as the case may be, within ten Business Days prior to the date the
first payment in respect of any portion of such excess Additional Interest
becomes due, such additional moneys or Government Obligations as are necessary
to satisfy the provisions of Section 401 or 1304 of the Original Indenture, as
the case may be, as if a discharge or Defeasance were being effected as of the
date of such subsequent deposit.
 
  Except as otherwise provided in or pursuant to the Indenture, at least 10
days prior to the first Interest Payment Date upon which Additional Interest
(for purposes of this paragraph, as defined in clause (i) of the definition
thereof) shall be payable, and at least 10 days prior to each date of payment
of principal and any premium or interest if there has been any change with
respect to the information set forth in the Officers' Certificate hereinafter
mentioned, the Corporation shall furnish the Trustee and any Paying Agent, if
other than the Trustee or the Corporation, with an Officers' Certificate
stating the amount of the Additional Interest payable per minimum authorized
denomination of the Series   Notes.
 
  Section 109. Limitations on Dividend and Certain Other Payments. The
Corporation covenants, for the benefit of the Holders of the Series   Notes,
that, subject to the next succeeding sentence, (a) the Corporation shall not
declare or pay any dividend on, or make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock, and (b) the Corporation shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees other than the Guarantee) issued by the
Corporation which rank pari passu with or junior to the Series   Notes (i) if
at such time the Corporation shall have given notice of its election to extend
an interest payment period for the Series   Notes and such extension shall be
continuing or (ii) if at such time an Event of Default with respect to the
Series   Notes shall have occurred and be continuing. The preceding sentence,
however, shall not restrict (A) any of the actions described in the preceding
sentence resulting from any reclassification of the Corporation's capital stock
or the exchange or conversion of one class or series of the Corporation's
capital stock for another class or series of the Corporation's capital stock,
(B) the declaration and payment of a dividend or distribution or similar share
purchase rights in the future, (C) repurchases, redemptions or other
acquisitions of shares of the Corporation's capital stock in connection with
any employment contract, benefit plan or other similar arrangement with or for
the benefit of employees, officers or directors or a stock purchase and
dividend reinvestment plan, (D) acquisitions of shares of the Corporation's
capital stock in connection with the issuance of shares of the Corporation's
capital stock (or securities convertible into or exchangeable for shares of the
Corporation's capital stock) as consideration in an acquisition transaction
that was entered into prior to the commencement of the relevant Extension
Period, (E) dividends or distributions in capital stock of the Corporation, (F)
the purchase of fractional interests in shares of the Corporation's capital
stock pursuant to the conversion or exchange provisions of such capital stock
or the security being converted or exchanged, or (G) mandatory sinking fund
payments with respect to any series of the Corporation's preferred stock or
preferred stock A; provided that the aggregate stated value of all such series
outstanding at the time of any such payment does not exceed
 
                                       8
<PAGE>
 
5% of the aggregate of (1) the total principal amount of all bonds or other
securities representing secured indebtedness issued or assumed by the
Corporation and then outstanding and (2) the capital and surplus of the
Corporation to be stated on the books of account of the Corporation after
giving effect to such payment; provided, however, that any moneys deposited
into any sinking fund and not in violation of this provision may thereafter be
applied to the purchase or redemption of such preferred stock or preferred
stock A in accordance with the terms of such sinking fund without regard to the
restrictions contained in this Section 109.
 
  Section 110. Covenants Regarding Securities Trust. For so long as the Trust
Securities remain outstanding, the Corporation covenants (i) directly or
indirectly to maintain 100% ownership of the Common Securities (as defined in
the Trust Agreement) of the Securities Trust; provided, however, that any
permitted successor of the Corporation under the Indenture may succeed to the
Corporation's ownership of such Common Securities, and (ii) to use its
reasonable efforts to cause the Securities Trust (a) to remain a statutory
business trust, except in connection with the distribution of Series   Notes to
the holders of Trust Securities in liquidation of the Securities Trust, the
redemption of all of the Trust Securities, or certain mergers, consolidations
or amalgamations, each as permitted under the Trust Agreement, and (b) to
otherwise continue to be classified as a grantor trust for United States
federal income tax purposes. The Corporation shall deliver to the Trustee, no
later than the Business Day on which the event occurs, written notice of the
liquidation, dissolution or winding-up of the Securities Trust if such
liquidation, dissolution or winding-up would occur earlier than the Stated
Maturity of the Series   Notes owned by such Securities Trust.
 
  Section 111. No Fiduciary Duty of Trustee to Holders of Trust Securities. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Trust
Securities and shall be entitled to rely on the delivery to it of a written
notice by a Person representing himself to be a holder of a Trust Security to
establish that such Person is such a holder.
 
  Section 112. Listing of Series   Notes. If the Series   Notes are to be
issued as a Global Security or Global Securities in connection with the
distribution of the Series   Notes to the holders of the Preferred Securities,
the Corporation shall use its best efforts to list such Series   Notes on the
New York Stock Exchange or any other exchange on which such Preferred
Securities are then listed. The Corporation shall notify the Trustee if and
when the Series   Notes become admitted to trading on the New York Stock
Exchange or any other national securities exchange.
 
  Section 113. Covenant Defeasance. Section 1303 of the Original Indenture
shall not apply to any of the Series   Notes.
 
  Section 114. Set-Off. Notwithstanding anything to the contrary in the
Indenture or in any Series   Note, prior to the dissolution of the Securities
Trust, the Corporation shall have the right to set off and apply against any
payment it is otherwise required to make hereunder or thereunder with respect
to the principal of or interest (including any Additional Interest) on the
Series   Notes with and to the extent the Corporation has theretofore made, or
is concurrently on the date of such payment making, a payment with respect to
the Preferred Securities under the Guarantee. Contemporaneously with, or as
promptly as practicable after, any such payment under the Guarantee, the
Corporation shall deliver to the Trustee an Officers' Certificate (upon which
the Trustee shall be entitled to rely conclusively without any requirement to
investigate the facts contained therein) to the
 
                                       9
<PAGE>
 
effect that such payment has been made and that, as a result of such payment,
the corresponding payment under the Series   Notes has been set off in
accordance with this Section 114.
 
  Section 115. Subordination. The indebtedness evidenced by the Series   Notes
shall be, to the extent and in the manner set forth in the Original Indenture,
subordinate and junior in right of payment to the prior payment in full of all
Senior Indebtedness (as defined in the Original Indenture) with respect to the
Series   Notes, and the Series   Notes shall rank pari passu in right of
payment with each other series of Securities issued under the Indenture, with
the exception of any series of Securities which by its terms provides
otherwise.
 
  Section 116. Paying Agent. The Trustee shall initially serve as Paying Agent
with respect to the Series   Notes, with the Place of Payment initially being
the Corporate Trust Office of the Trustee.

Indenture are made by the Corporation only and not by the Trustee, and all of
the provisions contained in the Original Indenture in respect of the rights,

Corporation shall remain primarily liable for the performance of all such
obligations. The Indenture may also be assigned by the Corporation in
connection with a transaction described in Article Eight of the Original
Indenture.
 
  Section 205. Enforcement by Holders of Preferred Securities of Right of
Holders to Receive Principal and Interest. So long as the Series   Notes are
held by the Property Trustee on behalf of the Securities Trust, a registered
holder of Preferred Securities may institute a legal proceeding directly
against the Corporation, without first instituting a legal proceeding directly
against or requesting or directing that action be taken by the Property Trustee
or any other Person, for enforcement of payment to such registered holder of
principal of or interest on Series   Notes having a principal amount equal to
the aggregate stated liquidation amount of such Preferred Securities of such
registered holder on or after the due dates therefor specified or provided for
in the
 
                                       10

Series   Notes. This Section 205 and Section 109 of this     Supplemental
Indenture are for the benefit of the registered holders of Preferred Securities
and, prior to the dissolution of the Securities Trust, may be enforced by such
holders. A holder of a Preferred Security shall not have the right, as such
holder, to enforce any other provision of the Indenture.

in its name and behalf by its duly authorized officers, all as of the day and
year first above written.

paid to the Person in whose name this Series    % Junior Subordinated Note due
      ,    (this "Security") is registered at the close of business on the
Regular Record Date as specified above next preceding such Interest Payment
Date; provided that any interest payable at Stated Maturity or on any
Redemption Date will be paid to the Person to whom principal
 
                                      A-1
<PAGE>
 
is payable. Except as otherwise provided in the Indenture, any such interest
not so punctually paid or duly provided for will forthwith cease to be payable
to the Holder on such Regular Record Date and may either be paid to the Person
in whose name this Security is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange, if any, on which the Securities of this series shall be
listed, and upon such notice as may be required by any such exchange, all as
more fully provided in said Indenture.
 
  Payments of interest on this Security will include interest accrued to but
excluding the respective Interest Payment Dates. Interest payments for this
Security shall be computed and paid on the basis of a 360-day year of twelve
30-day months. In the event that any date on which interest is payable on this
Security is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day that is a Business Day (and
without any interest or payment in respect of any such delay), except that, if
such Business Day is in the next succeeding calendar year, payment shall be
made on the immediately preceding Business Day, in each case with the same
force and effect as if made on the date the payment was originally payable.
"Business Day" means a day other than (i) a Saturday or a Sunday, (ii) a day on
which banks in New York, New York are authorized or obligated by law or
executive order to remain closed or (iii) a day on which the Corporate Trust
Office or the principal corporate trust office of the Property Trustee is
closed for business.
 
  The Corporation shall have the right at any time and from time to time during
the term of this Security to extend the interest payment period of such
Security for up to    consecutive quarters (each, an "Extension Period"), but
not beyond the Stated Maturity of this Security, during which Extension Periods
interest shall accrue on unpaid installments of interest at the Interest Rate,
compounded quarterly, to the date of payment to the extent permitted by
applicable law (such unpaid interest plus such interest thereon being called
"Deferred Interest"); provided, however, that the Corporation shall have the
right to make partial payments of interest on any Interest Payment Date during
any Extension Period. Upon the termination of each Extension Period, which
shall be an Interest Payment Date, the Corporation shall pay all Deferred
Interest on the next succeeding Interest Payment Date to the Person in whose
name this Security is registered at the close of business on the Regular Record
Date for such Interest Payment Date; provided that any Deferred Interest
payable at Stated Maturity or on any Redemption Date will be paid to the Person
to whom principal is payable. Prior to the termination of any such Extension
Period, the Corporation may further extend the interest payment period;
provided that such Extension Period together with all such previous and further
extensions thereof shall not exceed        (  ) consecutive quarters. Upon the
termination of any such Extension Period, and the payment of all accrued and
unpaid interest (including any Additional Interest) then due, the Corporation
may select a new Extension Period, subject to the above requirements. The
Corporation shall not (i) declare or pay any dividend or distribution on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock, and (ii) make any payment of interest, principal or premium,
if any, on or repay, repurchase or redeem any debt securities (including
guarantees other than the Guarantee) issued by the Corporation that rank pari
passu with or junior to this Security if the Corporation shall have given
notice of its

<PAGE>
 
election to extend an interest payment period for this Security and such
extension shall be continuing or if at such time an Event of Default with
respect to the series of which this Security is a part shall have occurred and
be continuing. The preceding sentence, however, shall not restrict (A) any of
the actions described in the preceding sentence resulting from any
reclassification of the Corporation's capital stock or the exchange or
conversion of one class or series of the Corporation's capital stock for
another class or series of the Corporation's capital stock, (B) the declaration
and payment of a dividend or distribution or similar share purchase rights in
the future, (C) repurchases, redemptions or other acquisitions of shares of the
Corporation's capital stock in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of employees,
officers or directors or a stock purchase and dividend reinvestment plan, (D)
acquisitions of shares of the Corporation's capital stock in connection with
the issuance of shares of the Corporation's capital stock (or securities
convertible into or exchangeable for shares of the Corporation's capital stock)
as consideration in an acquisition transaction that was entered into prior to
the commencement of the relevant Extension Period, (E) dividends or
distributions on capital stock of the Corporation, (F) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, or (G) mandatory sinking fund payments with
respect to any series of the Corporation's preferred stock or preferred stock
A; provided that the aggregate stated value of all such series outstanding at
the time of any such payment does not exceed 5% of the aggregate of (1) the
total principal amount of all bonds or other securities representing secured
indebtedness issued or assumed by the Corporation and then outstanding and (2)
the capital and surplus of the Corporation to be stated on the books of account
of the Corporation after giving effect to such payment; provided, however, that
any moneys deposited into any sinking fund and not in violation of this
provision may thereafter be applied to the purchase or redemption of such
preferred stock or preferred stock A in accordance with the terms of such
sinking fund without regard to the restrictions contained in this provision.
The Corporation shall give the Holder of this Security and the Trustee notice
of its selection or extension of an Extension Period at least one Business Day
prior to the earlier of (i) the Regular Record Date relating to the Interest
Payment Date on which the Extension Period is to commence or relating to the
Interest Payment Date on which an Extension Period that is being extended would
otherwise terminate or (ii) the date the Corporation or the Securities Trust is
required to give notice to the New York Stock Exchange or other applicable
self-regulatory organization of the record date or the date such distributions
are payable.
 
  The Corporation also shall be obligated to pay when due and without extension
all additional amounts as may be required so that the net amount received and
retained by the Holder of this Security (if the Holder is the Securities Trust)
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 such Holder would have
received had no such taxes, duties, assessments, or other governmental charges
been imposed.
 
  Payment of the principal of and interest (including Additional Interest, if
any) due at the Stated Maturity or earlier redemption of this Security shall be
made upon surrender of this Security, at the Corporate Trust Office of the
Trustee, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts.
Payment of interest (including interest on an Interest Payment Date) will be
made, subject to such surrender where
 
                                      A-3
<PAGE>
 
applicable, at the option of the Corporation, (i) by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register or (ii) by wire transfer at such place and to such account at
a banking institution in the United States as may be designated in writing to
the Trustee at least sixteen (16) days prior to the date for payment by the
Person entitled thereto.
 
  The indebtedness evidenced by this Security is, to the extent and in the
manner set forth in the Indenture, subordinate in right of payment to the prior
payment in full of all Senior Indebtedness (as defined in the Indenture), and
this Security is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this Security, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate
the subordination so provided and (c) appoints the Trustee his attorney-in-fact
for any and all such purposes. Each Holder hereof, by his acceptance hereof,
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness whether now
outstanding or hereafter incurred and waives reliance by each such holder upon
said provisions.
 
  REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET FORTH
ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE
SAME EFFECT AS IF SET FORTH AT THIS PLACE.
 
  Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.
 
  IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly
executed under its corporate seal.

  This is one of the Securities of the series designated therein referred to in
the within-mentioned Indenture.
 
                                          The Chase Manhattan Bank, as Trustee

                           (Reverse Side of Security)
 
  This Security is one of a duly authorized issue of Securities of the
Corporation (the "Securities"), issued and issuable in one or more series under
a Subordinated Indenture, dated as of December 1, 1997, as supplemented (the
"Indenture"), between the Corporation and The Chase Manhattan Bank, as Trustee
(the "Trustee," which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitation of rights, duties and
immunities thereunder of the Corporation, the Trustee and the Holders of the
Securities issued thereunder and of the terms upon which said Securities are,
and are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof as Series    % Junior Subordinated Notes due
  ,      (the "Series   Notes") in the aggregate principal amount of up to
$     . Capitalized terms used herein for which no definition is provided
herein shall have the meanings set forth in the Indenture.
 
  The Corporation shall have the right, subject to the terms and conditions of
the Indenture, to redeem this Security at any time on or after        ,      at
the option of the Corporation, without premium or penalty, in whole or in part,
at a Redemption Price equal to 100% of the principal amount to be redeemed plus
accrued but unpaid interest (including any Additional Interest) to the
Redemption Date. Upon the occurrence of a Special Event (as defined below), the
Corporation may, within 90 days following the occurrence thereof and subject to
the terms and conditions of the Indenture, redeem this Security without premium
or penalty, in whole, at a Redemption Price equal to 100% of the principal
amount thereof plus accrued but unpaid interest (including any Additional
Interest) to the Redemption Date. A Special Event may be a Tax Event or an
Investment Company Act Event. "Tax Event" means that the Administrative
Trustees and the Corporation shall have received an Opinion of Counsel
experienced in such matters to the effect that, as a result of (a) any
amendment to, or change (including any announced prospective change) in, laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein or (b) any amendment to, or
change in, an interpretation or application of such laws or regulations, there
is more than an insubstantial risk that (i) the Securities Trust would be
subject to United States federal income tax with respect to income accrued or
received on the Series   Notes, (ii) interest payable on the Series   Notes
would not be deductible by the Corporation for United States federal income tax
purposes, or (iii) the Securities Trust would be subject to more than a de
minimis amount of other taxes, duties or other governmental charges, which
change or amendment becomes effective on or after the Original Issue Date.
"Investment Company Act Event" means that the Administrative Trustees and the
Corporation shall 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, there is more than an insubstantial risk that the Securities Trust
is or will be considered an "investment company" that is required to be
registered under the Investment Company Act of 1940, as amended, which change
becomes effective on or after the Original Issue Date.
 
  In the event of redemption of this Security in part only, a new Security or
Securities of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the surrender hereof. The Securities of this
series will not have a sinking fund.
 
                                      A-6
<PAGE>
 
  If an Event of Default with respect to the Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.
 
  The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Corporation and the rights of the Holders of the Securities of all series
affected under the Indenture at any time by the Corporation and the Trustee
with the consent of the Holders of not less than a majority in principal amount
of the Outstanding Securities of all series affected thereby (voting as one
class). The Indenture contains provisions permitting the Holders of not less
than a majority in principal amount of the Outstanding Securities of all series
with respect to which a default under the Indenture shall have occurred and be
continuing (voting as one class), on behalf of the Holders of the Securities of
all such series, to waive, with certain exceptions, such default under the
Indenture and its consequences. The Indenture also permits the Holders of not
less than a majority in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Corporation with certain provisions of the
Indenture affecting such series. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.
 
  No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Corporation, which is
absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.
 
  As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation for such purpose, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Corporation and
the Security Registrar and duly executed by, the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Securities of this
series, of authorized denominations and of like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.
 
  As provided in and subject to the provisions of the Indenture, the Holder of
this Security shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than a majority in principal
amount of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and
the Trustee shall not have received from the Holders of a majority in principal
amount of Securities of this series at the time Outstanding a direction
inconsistent with such request and shall have failed to
 
                                      A-7
<PAGE>
 
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity. The foregoing shall not apply to any suit instituted by
the Holder of this Security for the enforcement of any payment of principal
hereof or any interest hereon on or after the respective due dates expressed
herein.
 
  The Indenture contains provisions for defeasance at any time of the entire
indebtedness of the Securities of this series upon compliance with certain
conditions set forth in the Indenture.
 
  Prior to due presentment of this Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security be overdue, and neither the
Corporation, the Trustee nor any such agent shall be affected by notice to the
contrary.
 
  The Securities of this series are issuable only in registered form without
coupons in denominations of $   and any integral multiple thereof. As provided
in the Indenture and subject to the limitations therein set forth, Securities
of this series are exchangeable for a like aggregate principal amount of
Securities of this series of a different authorized denomination, as requested
by the Holder surrendering the same upon surrender of the Security or
Securities to be exchanged at the office or agency of the Corporation.
 
  This Security shall be governed by, and construed in accordance with, the
internal laws of the State of New York.

corporation, as trustee (the "Trustee"). The Depositor and the Trustee hereby
agree as follows:

     1.  The trust created hereby shall be known as "Duke Energy Capital Trust 
III" (the "Trust"), in which name the Trustee or the Depositor, to the extent 
provided herein, may conduct the business of the Trust, make and execute 
contracts, and sue and be sued.

     2.  The Depositor hereby assigns, transfers, conveys and sets over to the 
Trust the sum of $10.  Such amount shall constitute the initial trust estate.  
It is the intention of the parties hereto that the Trust created hereby 
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code, 
12 Del. C. (S)3801, et seq. (the "Business Trust Act"), and that this document 
   -------          -- ----
constitute the governing instrument of the Trust.  The Trustee is hereby 
authorized and directed to execute and file a certificate of trust with the 
Delaware Secretary of State in such form as the Trustee may approve.

     3.  The Depositor and the Trustee will enter into an amended and restated
Trust Agreement or Declaration satisfactory to each such party to provide for
the contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and Common Securities referred to therein. Prior to the
execution and delivery of such amended and restated Trust Agreement or
Declaration, the Trustee shall not have any duty or obligation hereunder or with
respect to the trust estate, except as otherwise required by applicable law or
as may be necessary to obtain prior to such execution and delivery any licenses,
consents or approvals required by applicable law or otherwise. Notwithstanding
the foregoing, the Trustee may take all actions deemed proper as are necessary
to effect the transactions contemplated herein.

     4.  The Depositor is hereby authorized, in its sole discretion, (i) to file
with the Securities and Exchange Commission (the "Commission") and to execute,
in the case of the 1933 Act Registration Statement and 1934 Act Registration
Statement (as herein defined), on behalf of the Trust, (a) the Registration
Statement on Form S-3 (the "1933 Act Registration Statement"), including pre-
effective or post-effective amendments to such Registration Statement, relating
to the registration under the Securities Act of 1933, as amended (the "1933
Act"), of the Preferred Securities of the Trust, (b) any preliminary prospectus
or prospectus or supplement thereto relating to the Preferred Securities
required to be filed under the 1933 Act, and (c) if required, a Registration
Statement on Form 8-A or other appropriate form (the "1934 Act Registration
Statement")(including all pre-effective and post-effective amendments thereto)
relating to the registration of the Preferred Securities of the Trust under the
Securities Exchange Act of 1934, as amended; (ii) to file with the New York
Stock Exchange or any other exchange (collectively, the "Exchange") and execute
on behalf of the Trust a listing application and all other applications,
statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities to be listed
<PAGE>
 
on the Exchange; (iii) to file and execute on behalf of the Trust such
applications, reports, surety bonds, irrevocable consents, appointments of
attorney for service of process and other papers and documents as shall be
necessary or desirable to register the Preferred Securities under the securities
or "Blue Sky" laws of such jurisdictions as the Depositor, on behalf of the
Trust, may deem necessary or desirable; (iv) to execute, deliver and perform on
behalf of the Trust, an underwriting agreement with the Depositor and the
underwriter or underwriters of the Preferred Securities of the Trust; (v) to
execute, deliver and perform a depository agreement with the initial clearing
agency, relating to the Preferred Securities; and (vi) to apply for and obtain a
tax identification number for the Trust.
 
        In the event that any filing referred to in this Section 4 is required
by the rules and regulations of the Commission, PORTAL or state securities or
Blue Sky laws to be executed on behalf of the Trust by the Trustee, the Trustee,
in its capacity as trustee of the Trust, is hereby authorized and directed to
join in any such filing and to execute on behalf of the Trust any and all of the
foregoing, it being understood that Chase Manhattan Bank Delaware, in its
capacity as trustee of the Trust, shall not be required to join in any such
filing or execute on behalf of the Trust any such document unless required by
the rules and regulations of the Commission, PORTAL or state securities or Blue
Sky laws. In connection with all of the foregoing, the Depositor hereby
constitutes and appoints Robert T. Lucas III, as its true and lawful attorney-
in-fact and agent, with full power of substitution and resubsititution for the
Depositor or in the Depositor's name, place and stead, in any and all
capacities, to sign any and all amendments (including all pre-effective and
post-effective amendments) to the 1933 Act Registration Statement and any 1934
Act Registration Statement and to file the same, with all exhibits thereto, and
any other documents in connection therewith, with the Commission, granting unto
said attorney-in-fact and agent full power and authority to do and perform each
and every act and thing requisite and necessary to be done in connection
therewith, as fully to all intents and purposes as the Depositor might or could
do in person, hereby ratifying and confirming all that said attorney-in-fact and
agent or his respective substitute or substitutes, shall do or cause to be done
by virtue hereof.

        5.  This Declaration may be executed in one or more counterparts.
     
        6.  The number of trustees of the Trust initially shall be one and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware. Subject to the foregoing, the Depositor is entitled to
appoint or remove without cause any trustee of the Trust at any time. Any
trustee of the Trust may resign upon thirty days' prior notice to the Depositor.

        7.  This Declaration shall be governed by, and construed in accordance
with, the laws of the State of Delaware (without regard to conflict of laws
principles).

  (E) Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Trust and to
operate the Trust so that the Trust will not be deemed to be an "investment
company" required to be registered under the Investment Company Act, or taxed
as other than a grantor trust for United States federal income tax purposes and
so that the Junior Subordinated Notes will be treated as indebtedness of the
Depositor for United States federal income tax purposes. In this connection,
the Depositor and the Administrative Trustees are authorized to take any
action, not inconsistent with applicable law, the Certificate of Trust or this
Trust Agreement, that each of the Depositor and the Administrative Trustees

long as such action does not materially and adversely affect the interests of
the Holders of the Preferred Securities.

Securityholders and the Trust in accordance with this Trust Agreement. The
right, title and interest of the Property Trustee to the Junior Subordinated

corporation or other entity, except as described below. The Trust may at the
request of the Corporation, with the consent of the Administrative Trustees and
without the consent of the Holders of the Trust Securities, consolidate,
amalgamate, merge with or into, or be replaced by a trust organized as such
under the laws of any state; provided that (i) such successor entity either (x)
expressly assumes all of the obligations of the Trust with respect to the Trust
Securities or (y) substitutes for the Preferred Securities and the Common
Securities other securities having substantially the same terms as the Trust
Securities (herein referred to as the "Successor Securities") so long as the
Successor Securities rank the same as the Trust Securities rank in priority
with respect to Distributions and payments upon liquidation, redemption and
otherwise, (ii) the Corporation expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of legal title to the Junior Subordinated Notes, (iii) the Preferred
Securities or any Successor Securities are listed, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on which the Preferred Securities are then
listed, (iv) such merger, consolidation, amalgamation or replacement does not
cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such consolidation,
 
                                       14
<PAGE>
 
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, (vi) such successor entity
has a purpose substantially identical to that of the Trust, (vii) prior to such
consolidation, amalgamation, merger or replacement, the Corporation and the
Property Trustee have received an Opinion of Counsel experienced in such
matters to the effect that (A) such 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, and (B) following such consolidation, amalgamation, merger or
replacement, neither the Trust nor such successor entity will be required to
register as an investment company under the Investment Company Act, and (viii)
the Corporation owns all of the common securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee. Notwithstanding
the foregoing, the Trust shall not, except with the consent of Holders of 100%
in Liquidation Amount of the Trust Securities, consolidate, amalgamate, merge
with or into, or be replaced by any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger or replacement would cause the Trust or the
successor entity to be classified as other than a grantor trust for United
States federal income tax purposes.

property deposited or held from time to time in the Payment Account shall be
held by the Property Trustee in the Payment Account for the exclusive benefit
of the Securityholders and for distribution as herein provided, including (and
subject to) any priority of payments provided for herein.

                           Distributions; Redemption
 
Section 4.01 Distributions.
 
  (a) Distributions on the Trust Securities shall be cumulative and accrue from
the Issue Date and, except in the event that the Depositor exercises its right
to extend the interest payment period for the Junior Subordinated Notes
pursuant to Section 104 of the Supplemental Indenture, shall be
 
                                       15
<PAGE>
 
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year, commencing on     ,   . If any date on which Distributions are
otherwise payable on the Trust Securities is not a Business Day, then the
payment of such Distribution shall be made on the next succeeding day which is
a Business Day (and without any interest or other payment in respect of any
such delay) except that, if such Business Day is in the next succeeding
calendar year, payment of such Distribution shall be made on the immediately
preceding Business Day, in each case, with the same force and effect as if made
on such date (each such date, a "Distribution Date").
 
  (b) Distributions payable on the Trust Securities shall be fixed at a rate of
  % per annum of the Liquidation Amount of the Trust Securities. The amount of
Distributions payable for any full quarterly period shall be computed on the
basis of twelve 30-day months and a 360-day year. If the interest payment
period for the Junior Subordinated Notes is extended pursuant to Section 104 of
the Supplemental Indenture (an "Extension Period"), then the rate per annum at
which Distributions on the Trust Securities accumulate shall be increased by an
amount such that the aggregate amount of Distributions that accumulate on all
Trust Securities during any such Extension Period is equal to the aggregate
amount of interest (including interest payable on unpaid interest at the
percentage rate per annum set forth above, compounded quarterly, to the extent
permitted by applicable law) that accrues during any such Extension Period on
the Junior Subordinated Notes. The payment of such deferred interest, together
with interest thereon, will be distributed, if funds are legally available
therefor, to the Holders of the Trust Securities (as they appear on the books
and records of the Trust on the record date (as specified in Section 4.01(d))
next following the termination of such Extension Period) as received at the end
of any Extension Period. The amount of Distributions payable for any period
shall include the Additional Amounts, if any.
 
  (c) Distributions on the Trust Securities shall be made and shall be deemed
payable on each Distribution Date only to the extent that the Trust has legally
and immediately available funds in the Payment Account for the payment of such
Distributions.
 
  (d) Distributions (including Additional Amounts, if any) on the Trust
Securities on each Distribution Date shall be payable to the Holders thereof as
they appear on the Security Register for the Trust Securities on the relevant
record date, which shall be the close of business on the fifteenth calendar day
prior to the relevant Distribution Date.
 
  Each Trust Security upon registration of transfer of or in exchange for or in
lieu of any other Trust Security shall carry the rights of Distributions
accrued (including Additional Amounts, if any) and unpaid, and to accrue
(including Additional Amounts, if any), which were carried by such other Trust
Security.
 
  Section 4.02 Redemption.
 
  (a) On each Redemption Date with respect to the Junior Subordinated Notes,
the Trust will be required to redeem a Like Amount of Trust Securities at the
Redemption Price.
 
  (b) Notice of redemption shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register. All notices of
redemption shall state:
 
    (i) the Redemption Date;
 
                                       16
<PAGE>
 
    (ii) the Redemption Price;
 
    (iii) the CUSIP number;
 
    (iv) if less than all the Outstanding Trust Securities are to be
  redeemed, the total Liquidation Amount of the Trust Securities to be
  redeemed; and
 
    (v) that on the Redemption Date the Redemption Price will become due and
  payable upon each such Trust Security to be redeemed and the Distributions
  thereon will cease to accrue on and after such date.
 
  (c) The Trust Securities redeemed on each Redemption Date shall be redeemed
at the Redemption Price with the proceeds from the contemporaneous redemption
of Junior Subordinated Notes. Redemptions of the Trust Securities shall be made
and the Redemption Price shall be deemed payable on each Redemption Date only
to the extent that the Trust has funds legally and immediately available in the
Payment Account for the payment of such Redemption Price.
 
  (d) If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 2:00 P.M. New York City time, on the Redemption
Date, subject to Section 4.02(c), the Property Trustee will, so long as the
Preferred Securities are in book-entry only form, irrevocably deposit with the
Clearing Agency for the Preferred Securities funds sufficient to pay the
applicable Redemption Price. If the Preferred Securities are not in book-entry
only form, the Property Trustee, subject to Section 4.02(c), shall irrevocably
deposit with the Paying Agent funds sufficient to pay the applicable Redemption
Price and will give the Paying Agent irrevocable instructions to pay the
Redemption Price to the Holders thereof upon surrender of their Preferred
Securities Certificates. Notwithstanding the foregoing, Distributions payable
on or prior to the Redemption Date for any Trust Securities called for
redemption shall be payable to the Holders of such Trust Securities as they
appear on the Security Register for the Trust Securities on the relevant record
dates for the related Distribution Dates. If notice of redemption shall have
been given and funds deposited as required, then immediately prior to the close
of business on the date of such deposit, all rights of Securityholders holding
Trust Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price, but without interest, and such
Securities will cease to be outstanding. In the event that any date on which
any Redemption Price is payable is not a Business Day, then payment of the
Redemption Price payable on such date shall be made on the next succeeding day
which is a Business Day (and without any interest or other payment in respect
of any such delay) except that, if such Business Day is in the next succeeding
calendar year, payment of such Redemption Price shall be made on the
immediately preceding Business Day, in each case, with the same force and
effect as if made on such date. In the event that payment of the Redemption
Price in respect of Trust Securities is improperly withheld or refused and not
paid either by the Trust or by the Depositor pursuant to the Guarantee,
Distributions on such Trust Securities will continue to accrue at the then
applicable rate, from such Redemption Date originally established by the Trust
for such Preferred Securities to the date such Redemption Price is actually
paid.
 
  (e) Payment of the Redemption Price on the Trust Securities shall be made to
the recordholders thereof as they appear on the Security Register for the Trust
Securities on the relevant record date, which shall be the close of business on
the fifteenth calendar day prior to the Redemption Date.

  (f) If less than all the Outstanding Trust Securities are to be redeemed on a
Redemption Date, then the aggregate Liquidation Amount of Trust Securities to
be redeemed shall be allocated 3% to the Common Securities and 97% to the
Preferred Securities, with such adjustments that each amount so allocated shall
be divisible by $ . The particular Preferred Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Property
Trustee from the Outstanding Preferred Securities not previously called for
redemption, by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $  or integral multiples thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $ ; provided, however, that
before undertaking redemption of the Preferred Securities on other than a pro
rata basis, the Property Trustee shall have received an Opinion of Counsel that
the status of the Trust as a grantor trust for United States federal income tax
purposes would not be adversely affected. The Property Trustee shall promptly
notify the Security Registrar in writing of the Preferred Securities selected
for redemption and, in the case of any Preferred Securities selected for
partial redemption, the Liquidation Amount thereof to be redeemed. For all
purposes of this Trust Agreement, unless the context otherwise requires, all
provisions relating to the redemption of Preferred Securities shall relate, in
the case of any Preferred Securities redeemed or to be redeemed only in part,
to the portion of the Liquidation Amount of Preferred Securities which has been
or is to be redeemed.
 
  (g) Subject to the foregoing provisions of Section 4.02 and to applicable law
(including, without limitation, United States federal securities laws), the
Corporation or its Affiliates may, at any time and from time to time, purchase
outstanding Preferred Securities by tender, in the open market or by private
agreement.
 
  Section 4.03 Subordination of Common Securities.
 
  (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made pro rata based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date an
Indenture Event of Default shall have occurred and be continuing, no payment of
any Distribution (including Additional Amounts, if applicable) on, or
Redemption Price of, any Common Security, and no other payment on account of
the redemption, liquidation or other acquisition of Common Securities, shall be
made unless payment in full in cash of all accumulated and unpaid Distributions
(including Additional Amounts, if applicable) on all Outstanding Preferred
Securities for all distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities, shall have been made or provided
for, and all funds immediately available to the Property Trustee shall first be
applied to the payment in full in cash of all Distributions (including
Additional Amounts, if applicable) on, or the Redemption Price of, Preferred
Securities then due and payable.
 
  (b) In the case of the occurrence of any Indenture Event of Default, the
Holder of Common Securities will be deemed to have waived any such Event of
Default under this Trust Agreement until the effect of all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Events of Default under this Trust
Agreement with respect to the Preferred Securities have been so cured, waived
or otherwise eliminated, the Property Trustee shall act solely on behalf of the
Holders of the Preferred Securities and not the Holder of the
 
                                       18
<PAGE>
 
Common Securities, and only the Holders of the Preferred Securities will have
the right to direct the Property Trustee to act on their behalf.
 
  Section 4.04 Payment Procedures. Payments in respect of the Preferred
Securities shall be made by check mailed to the address of the Person entitled
thereto as such address shall appear on the Security Register or, if the
Preferred Securities are held by a Clearing Agency, such Distributions shall be
made to the Clearing Agency, which shall credit the relevant Persons' accounts
at such Clearing Agency on the applicable distribution dates. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Holder of the Common
Securities.
 
  Section 4.05 Tax Returns and Reports. The Administrative Trustee(s) shall
prepare (or cause to be prepared), at the Depositor's expense, and file all
United States federal, state and local tax and information returns and reports
required to be filed by or in respect of the Trust. The Administrative
Trustee(s) shall provide or cause to be provided on a timely basis to each
Holder any Internal Revenue Service form required to be so provided in respect
of the Trust Securities.

  Section 5.01 Initial Ownership. Upon the formation of the Trust by the
contribution by the Depositor pursuant to Section 2.03 and until the issuance
of the Trust Securities, and at any time during which no Trust Securities are
outstanding, the Depositor shall be the sole beneficial owner of the Trust.
 
  Section 5.02 The Trust Securities Certificates. Each of the Preferred and
Common Securities Certificates shall be issued in minimum denominations of $
and integral multiples in excess thereof. The Trust Securities Certificates
shall be executed on behalf of the Trust by manual or facsimile signature of at
least one Administrative Trustee. Trust Securities Certificates bearing the
manual or facsimile signatures of individuals who were, at the time when such
signatures shall have been affixed, authorized to sign on behalf of the Trust,
shall be validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the authentication and delivery of such Trust Securities
Certificates or did not hold such offices at the date of authentication and
delivery of such Trust Securities Certificates. A transferee of a Trust
Securities Certificate shall become a Securityholder, and shall be entitled to
the rights and subject to the obligations of a Securityholder hereunder, upon
due registration of such Trust Securities Certificate in such transferee's name
pursuant to Section 5.04.
 
  Section 5.03 Authentication of Trust Securities Certificates. On the Issue
Date, the Administrative Trustees shall cause Trust Securities Certificates, in
an aggregate Liquidation Amount as provided in Sections 2.04 and 2.05, to be
executed on behalf of the Trust, authenticated and delivered to or upon the
written order of the Depositor signed by its Chairman of the Board, its
President or any Vice President, without further corporate action by the
Depositor, in authorized denominations. No Trust Securities Certificate shall
entitle its Holder to any benefit under this Trust
 
                                       19
<PAGE>
 
Agreement, or shall be valid for any purpose, unless there shall appear on such
Trust Securities Certificate a certificate of authentication substantially in
the form set forth in Exhibit E or Exhibit C, as applicable, executed by at
least one Administrative Trustee by manual signature; such authentication shall
constitute conclusive evidence that such Trust Securities Certificate shall
have been duly authenticated and delivered hereunder. All Trust Securities
Certificates shall be dated the date of their authentication.
 
  Section 5.04 Registration of Transfer and Exchange of Preferred Securities
Certificates. The Security Registrar shall keep or cause to be kept, at the
office or agency maintained pursuant to Section 5.08, a Security Register in
which, subject to such reasonable regulations as it may prescribe, the Security
Registrar shall provide for the registration of Preferred Securities
Certificates and the Common Securities Certificates (subject to Section 5.10 in
the case of the Common Securities Certificates) and registration of transfers
and exchanges of Preferred Securities Certificates as herein provided. The
Property Trustee shall be the initial Security Registrar.
 
  Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.08, the
Administrative Trustees shall execute, authenticate and deliver in the name of
the designated transferee or transferees, one or more new Preferred Securities
Certificates in authorized denominations of a like aggregate Liquidation Amount
dated the date of authentication by the Administrative Trustee or Trustees. The
Security Registrar shall not be required to register the transfer of any
Preferred Securities that have been called for redemption. At the option of a
Holder, Preferred Securities Certificates may be exchanged for other Preferred
Securities Certificates in authorized denominations of the same class and of a
like aggregate Liquidation Amount upon surrender of the Preferred Securities
Certificates to be exchanged at the office or agency maintained pursuant to
Section 5.08.
 
  Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Administrative Trustees and
the Security Registrar duly executed by the Holder or such Holder's attorney
duly authorized in writing. Each Preferred Securities Certificate surrendered
for registration of transfer or exchange shall be cancelled and subsequently
disposed of by the Security Registrar in accordance with its customary
practice.
 
  No service charge shall be made for any registration of transfer or exchange
of Preferred Securities Certificates, but the Security Registrar or the
Administrative Trustees may require payment of a sum sufficient to cover any
tax or governmental charge that may be imposed in connection with any transfer
or exchange of Preferred Securities Certificates.
 
  Section 5.05 Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates. If (a) any mutilated Trust Securities Certificate shall be
surrendered to the Security Registrar, or if the Security Registrar shall
receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Securities Certificate and (b) there shall be delivered to the Security
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees or any one of them on behalf of the
Trust shall execute and authenticate and make available for delivery, in
exchange for or in lieu of any such mutilated,
 
                                       20

destroyed, lost or stolen Trust Securities Certificate, a new Trust Securities
Certificate of like class, tenor and denomination. In connection with the
issuance of any new Trust Securities Certificate under this Section, the
Administrative Trustees or the Security Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith. Any duplicate Trust Securities Certificate
issued pursuant to this Section shall constitute conclusive evidence of an
ownership interest in the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Securities Certificate shall be found at any
time.
 
  Section 5.06 Persons Deemed Securityholders. Prior to due presentation of a
Trust Securities Certificate for registration of transfer, the Trustees or the
Security Registrar shall treat the Person in whose name any Trust Securities
Certificate shall be registered in the Security Register as the owner of such
Trust Securities Certificate for the purpose of receiving Distributions
(subject to Section 4.01(d)) and for all other purposes whatsoever, and neither
the Trustees nor the Security Registrar shall be bound by any notice to the
contrary.
 
  Section 5.07 Access to List of Securityholders' Names and Addresses. The
Administrative Trustees shall furnish or cause to be furnished to (i) the
Depositor and the Property Trustee semi-annually, not later than June 1 and
December 1 in each year and (ii) the Depositor or the Property Trustee, as the
case may be, within 30 days after receipt by any Administrative Trustee of a
request therefor from the Depositor or the Property Trustee, as the case may
be, in writing, a list, in such form as the Depositor or the Property Trustee,
as the case may be, may reasonably require, of the names and addresses of the
Securityholders as of a date not more than 15 days prior to the time such list
is furnished; provided that the Administrative Trustees shall not be obligated
to provide such list at any time such list does not differ from the most recent
list given to the Depositor and the Property Trustee by the Administrative
Trustees or at any time the Property Trustee is the Security Registrar. If
three or more Securityholders or one or more Holders of Trust Securities
Certificates evidencing not less than 25% of the outstanding Liquidation Amount
apply in writing to the Administrative Trustees, and such application states
that the applicants desire to communicate with other Securityholders with
respect to their rights under this Trust Agreement or under the Trust
Securities Certificates and such application is accompanied by a copy of the
communication that such applicants propose to transmit, then the Administrative
Trustees shall, within five Business Days after the receipt of such
application, afford such applicants access during normal business hours to the
current list of Securityholders. Each Holder, by receiving and holding a Trust
Securities Certificate, shall be deemed to have agreed not to hold either the
Depositor or the Administrative Trustees accountable by reason of the
disclosure of its name and address, regardless of the source from which such
information was derived.
 
  Section 5.08 Maintenance of Office or Agency. The Administrative Trustees
shall maintain in the Borough of Manhattan, New York, an office or offices or
agency or agencies where Preferred Securities Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Trustees in respect of the Trust Securities Certificates may be
served. The Administrative Trustees initially designate The Chase Manhattan
Bank, 450 West 33rd Street, New York, New York 10001 as the principal agency
for such purposes. The Administrative Trustees shall give prompt written notice
to the Depositor and to the Securityholders of any change in the location of
the Security Register or any such office or agency.

  Section 5.09 Appointment of Paying Agent. The Paying Agent shall make
Distributions and other payments provided hereby to Securityholders from the
Payment Account and shall report the amounts of such Distributions and payments
to the Property Trustee and the Administrative Trustees. Any Paying Agent shall
have the revocable power to withdraw funds from the Payment Account for the
purpose of making the Distributions and payments provided hereby. The
Administrative Trustees may revoke such power and remove the Paying Agent if
such Trustees determine in their sole discretion that the Paying Agent shall
have failed to perform its obligations under this Trust Agreement in any
material respect. The Paying Agent shall initially be the Property Trustee, and
it may choose any co-paying agent that is acceptable to the Administrative
Trustees and the Depositor. Any Person acting as Paying Agent shall be
permitted to resign as Paying Agent upon 30 days' written notice to the
Administrative Trustees and the Depositor. In the event that a Paying Agent
shall resign or be removed, the Administrative Trustees shall appoint a
successor that is acceptable to the Depositor to act as Paying Agent (which
shall be a bank or trust company). The Administrative Trustees shall cause such
successor Paying Agent or any additional Paying Agent appointed by the
Administrative Trustees to execute and deliver to the Trustees an instrument in
which such successor Paying Agent or additional Paying Agent shall agree with
the Trustees that as Paying Agent, such successor Paying Agent or additional
Paying Agent will hold all sums, if any, held by it for payment to the
Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders. The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to
the Property Trustee. The provisions of Sections 8.01, 8.03 and 8.06 shall
apply to the Property Trustee also in its role as Paying Agent, for so long as
the Property Trustee shall act as Paying Agent and, to the extent applicable,
to any other paying agent appointed hereunder. Any reference in this Agreement
to the Paying Agent shall include any co-paying agent unless the context
requires otherwise.
 
  Section 5.10 Ownership of Common Securities by Depositor. On the Issue Date,
the Depositor shall acquire, and thereafter retain, beneficial and record
ownership of the Common Securities. Any attempted transfer of the Common
Securities, except for transfers by operation of law or to an Affiliate of the
Depositor or a permitted successor under Section 801 of the Subordinated
Indenture, shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor and its permitted transferees to
contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS
PROVIDED IN THE TRUST AGREEMENT REFERRED TO HEREIN."
 
  Section 5.11 Book-Entry Preferred Securities Certificates; Common Securities
Certificate.
 
  (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Trust. Such Preferred Securities Certificate or Certificates
shall initially be registered on the Security Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no Owner will receive a
definitive Preferred Securities Certificate representing such beneficial
owner's interest in such Preferred Securities, except as provided in Section
5.13.

Unless and until Definitive Preferred Securities Certificates have been issued
to Owners pursuant to Section 5.13:
 
    (i) the provisions of this Section 5.11(a) shall be in full force and
  effect;
 
    (ii) the Security Registrar and the Trustees shall be entitled to deal
  with the Clearing Agency for all purposes of this Trust Agreement relating
  to the Book-Entry Preferred Securities Certificates (including the payment
  of principal of and interest on the Book-Entry Preferred Securities and the
  giving of instructions or directions to Owners of Book-Entry Preferred
  Securities) as the sole Holder of Book-Entry Preferred Securities and shall
  have no obligations to the Owners thereof;
 
    (iii) to the extent that the provisions of this Section conflict with any
  other provisions of this Trust Agreement, the provisions of this Section
  shall control;
 
    (iv) the rights of the Owners of the Book-Entry Preferred Securities
  Certificates shall be exercised only through the Clearing Agency and shall
  be limited to those established by law and agreements between such Owners
  and the Clearing Agency and/or the Clearing Agency Participants. Pursuant
  to the Certificate Depository Agreement, unless and until Definitive
  Preferred Securities Certificates are issued pursuant to Section 5.13, the
  Clearing Agency will make book-entry transfers among the Clearing Agency
  Participants and receive and transmit payments on the Preferred Securities
  to such Clearing Agency Participants; and
 
    (v) whenever this Trust Agreement requires or permits actions to be taken
  based upon instructions or directions of Holders of Trust Securities
  Certificates evidencing a specified percentage of the aggregate Liquidation
  Amount, the Clearing Agency shall be deemed to represent such percentage
  only to the extent that it has received instructions to such effect from
  Owners and/or Clearing Agency Participants owning or representing,
  respectively, such required percentage of the beneficial interest in the
  applicable class of Trust Securities Certificates and has delivered such
  instructions to the Trustees.
 
  (b) A single Common Securities Certificate representing the Common Securities
shall be issued to the Depositor in the form of a definitive Common Securities
Certificate.
 
  Section 5.12 Notices to Clearing Agency. To the extent a notice or other
communication to the Owners is required under this Trust Agreement, unless and
until Definitive Preferred Securities Certificates shall have been issued to
Owners pursuant to Section 5.13, the Trustees shall give all such notices and
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no obligations to the Owners.
 
  Section 5.13 Definitive Preferred Securities Certificates. If (i) the
Depositor advises the Trustees in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities with respect to the
Preferred Securities Certificates, and the Depositor is unable to locate a
qualified successor within 90 days of receipt by the Depositor of such written
advice, or (ii) the Depositor at its option advises the Trustees in writing
that it elects to terminate the book-entry system through the Clearing Agency,
then the Administrative Trustees shall notify the Clearing Agency and Holders
of the Preferred Securities. Upon surrender to the Administrative Trustees of
the typewritten Preferred Securities Certificate or Certificates representing
the Book-Entry Preferred Securities Certificates by the Clearing Agency,
accompanied by registration instructions, the
 
                                       23
<PAGE>
 
Administrative Trustees or any one of them shall execute and authenticate the
Definitive Preferred Securities Certificates in accordance with the
instructions of the Clearing Agency. Neither the Security Registrar nor the
Trustees shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Preferred Securities Certificates, the Trustees
shall recognize the Holders of the Definitive Preferred Securities Certificates
as Securityholders. The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidence by the
execution thereof by the Administrative Trustees or any one of them.
 
  Section 5.14 Rights of Securityholders. The legal title to the Trust Property
is vested exclusively in the Property Trustee (in its capacity as such) in
accordance with Section 2.09, and the Securityholders shall not have any right
or title therein other than the undivided beneficial
ownership interest in the assets of the Trust conferred by their Trust
Securities, and they shall have no right to call for any partition or division
of property, profits or rights of the Trust except as described below. The
Trust Securities shall be personal property giving only the rights specifically
set forth therein and in this Trust Agreement. The Trust Securities shall have
no preemptive or other similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. Except as otherwise provided in the
Expense Agreement and Section 10.01 hereof with respect to the Depositor, the
Holders of the Trust Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware.

  Section 6.01 Limitations on Voting Rights.
 
  (a) Except as provided in this Section, in Section 8.10 or Section 10.03 of
this Trust Agreement, in the Subordinated Indenture, and as otherwise required
by law, no Holder of Preferred Securities shall have any right to vote or in
any manner otherwise control the administration, operation and management of
the Trust or the obligations of the parties hereto, nor shall anything herein
set forth, or contained in the terms of the Trust Securities Certificates, be
construed so as to constitute the Securityholders from time to time as partners
or members of an association.
 
  (b) So long as any Junior Subordinated Notes are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Indenture Trustee, or
executing any trust or power conferred on the Indenture Trustee with respect to
such Junior Subordinated Notes, (ii) consent to waive any past default which is
waivable under Section 513 of the Subordinated Indenture, (iii) exercise any
right to rescind or annul a declaration that the principal of all the Junior
Subordinated Notes shall be due and payable or (iv) consent to any amendment,
modification or termination of the Subordinated Indenture or the Junior
Subordinated Notes, where such consent shall be required, or to any other
action, as holder of the Junior Subordinated Notes, under the Subordinated
Indenture, without, in each case, obtaining the prior approval of the Holders
of at least 66 2/3% in Liquidation Amount of the Outstanding Preferred
 
                                       24

Securities; provided, however, that where a consent under the Subordinated
Indenture would require the consent of each holder of Junior Subordinated Notes
affected thereby, no such consent shall be given by the Trustees without the
prior written consent of each Holder of Preferred Securities. The Trustees
shall not revoke any action previously authorized or approved by a vote of the
Holders of Preferred Securities, except pursuant to a subsequent vote of the
Holders of Preferred Securities. The Property Trustee shall notify all Holders
of the Preferred Securities of any notice of default received from the
Indenture Trustee with respect to the Junior Subordinated Notes.
 
  (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely
affect the powers, preferences or special rights of the Preferred Securities,
whether by way of amendment to this Trust Agreement or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than pursuant to the
terms of this Trust Agreement, then the Holders of Outstanding Preferred
Securities as a class will be entitled to vote on such amendment or proposal
and such amendment or proposal shall not be effective except with the approval
of the Holders of at least 66 2/3% in Liquidation Amount of the Outstanding
Preferred Securities.
 
  Section 6.02 Notice of Meetings. Notice of all meetings of the Preferred
Securityholders, stating the time, place and purpose of the meeting, shall be
given by the Administrative Trustees pursuant to Section 10.08 to each
Preferred Securityholder of record, at his registered address, at least 15 days
and not more than 90 days before the meeting. At any such meeting, any business
properly before the meeting may be so considered whether or not stated in the
notice of the meeting. Any adjourned meeting may be held as adjourned without
further notice. Any and all notice to which any Preferred Securityholder
hereunder may be entitled and any and all communications shall be deemed duly
served or given if mailed, postage prepaid, addressed to any Preferred
Securityholder of record at his last known address as recorded on the Security
Register.
 
  Section 6.03 Meetings of Preferred Securityholders. No annual meeting of
Securityholders is required to be held. The Administrative Trustees, however,
shall call a meeting of Securityholders to vote on any matter upon the written
request of the Preferred Securityholders of record of 25% of the Preferred
Securities (based upon their Liquidation Amount), and the Administrative
Trustees or the Property Trustee may, at any time in their discretion, call a
meeting of Preferred Securityholders to vote on any matters as to which
Preferred Securityholders are entitled to vote.
 
  Preferred Securityholders of record of 50% of the Preferred Securities (based
upon their Liquidation Amount), present in person or by proxy, shall constitute
a quorum at any meeting of Securityholders.
 
  If a quorum is present at a meeting, an affirmative vote by the Preferred
Securityholders of record present, in person or by proxy, holding more than 66
2/3% of the Preferred Securities (based upon their Liquidation Amount) held by
the Preferred Securityholders of record present, either in person or by proxy,
at such meeting shall constitute the action of the Securityholders, unless this
Trust Agreement requires a greater proportion of affirmative votes.
 
  Section 6.04 Voting Rights. Securityholders shall be entitled to one vote for
each $25 of Liquidation Amount represented by their Trust Securities in respect
of any matter as to which such Securityholders are entitled to vote.
 
                                       25

  Section 6.05 Proxies, etc. At any meeting of Securityholders, any
Securityholder entitled to vote may vote by proxy, provided that no proxy shall
be voted at any meeting unless it shall have been placed on file with the
Administrative Trustees, or with such other officer or agent of the Trust as
the Administrative Trustees may direct, for verification prior to the time at
which such vote shall be taken. Pursuant to a resolution of the Property
Trustee, proxies may be solicited in the name of the Property Trustee or one or
more officers of the Property Trustee. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several Persons,
any one of them may vote at any meeting in person or by proxy in respect of
such Trust Securities, but if more than one of them shall be present at such
meeting in person or by proxy, and such joint owners or their proxies so
present disagree as to any vote to be cast, such vote shall not be received in
respect of such Trust Securities. A proxy purporting to be executed by or on
behalf of a Securityholder shall be deemed valid unless challenged at or prior
to its exercise, and the burden of proving invalidity shall rest on the
challenger. No proxy shall be valid more than three years after its date of
execution.
 
  Section 6.06 Securityholder Action by Written Consent. Any action which may
be taken by Securityholders at a meeting may be taken without a meeting if
Securityholders holding at least 66 2/3% of all outstanding Trust Securities
entitled to vote in respect of such action (or such other proportion thereof as
shall be required by any express provision of this Trust Agreement) shall
consent to the action in writing (based upon their Liquidation Amount).
 
  Section 6.07 Record Date for Voting and Other Purposes. For the purposes of
determining the Securityholders who are entitled to notice of and to vote at
any meeting or by written consent, or to participate in any Distribution on the
Trust Securities in respect of which a record date is not otherwise provided
for in this Trust Agreement, or for the purpose of any other action, the
Administrative Trustees may from time to time fix a date, not more than 90 days
prior to the date of any meeting of Securityholders or the payment of any
Distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.
 
  Section 6.08 Acts of Securityholders. Any request, demand, authorization,
direction, notice, consent, waiver or other action provided or permitted by
this Trust Agreement to be given, made or taken by Securityholders may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Securityholders in person or by an agent appointed in
writing; and, except as otherwise expressly provided herein, such action shall
become effective when such instrument or instruments are delivered to the
Administrative Trustees. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Trust Agreement and (subject to
Section 8.01) conclusive in favor of the Trustees, if made in the manner
provided in this Section.
 
  The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgements of deeds, certifying that the individual signing such
instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also
 
                                       26
<PAGE>
 
constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustees
deem sufficient.
 
  The ownership of Preferred Securities shall be proved by the Security
Register.
 
  Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.
 
  Without limiting the foregoing, a Securityholder entitled hereunder to take
any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to
such appointment with regard to all or any part of such Liquidation Amount.
 
  If any dispute shall arise between the Holders of Trust Securities and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder
or Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.
 
  Section 6.09 Inspection of Records. Upon reasonable notice to the Trustees,
the records of the Trust shall be open to inspection by a Securityholder during
normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

                                  ARTICLE VIII
 
                                  The Trustees
 
  Section 8.01 Certain Duties and Responsibilities.
 
  (a) The rights, duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and the Delaware Business Trust Act (except
that the immunities and standard of care of the Property Trustee shall be
governed by New York law) and, in the case of the Property Trustee, the Trust
Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the
 
                                       28
<PAGE>
 
performance of any of their duties hereunder, or in the exercise of any of
their rights or powers, if they shall have reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to them. Whether or not therein expressly
so provided, every provision of this Trust Agreement relating to the conduct or
affecting the liability of or affording protection to the Trustees shall be
subject to the provisions of this Section.
 
  (b) All payments made by the Property Trustee in respect of the Trust
Securities shall be made only from the income and proceeds from the Trust
Property and only to the extent that there shall be sufficient income or
proceeds from the Trust Property to enable the Property Trustee to make
payments in accordance with the terms hereof. Each Securityholder, by its
acceptance of a Trust Security, agrees that it will look solely to the income
and proceeds from the Trust Property to the extent available for distribution
to it as herein provided and that the Trustees are not personally liable to it
for any amount distributable in respect of any Trust Security or for any other
liability in respect of any Trust Security. This Section 8.01(b) does not limit
the liability of the Trustees expressly set forth elsewhere in this Trust
Agreement or, in the case of the Property Trustee, in the Trust Indenture Act.
 
  Section 8.02 Notice of Defaults. Within 90 days after the occurrence of any
default, the Property Trustee shall transmit, in the manner and to the extent
provided in Section 10.08, notice of any such default known to the Property
Trustee to the Securityholders, the Administrative Trustees and the Depositor,
unless such default shall have been cured or waived. For the purpose of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default.
 
  Section 8.03 Certain Rights of Property Trustee. Subject to the provisions of
Section 8.01 and except as provided by law:
 
    (i) the Property Trustee may rely and shall be protected in acting or
  refraining from acting in good faith upon any resolution, Opinion of
  Counsel, certificate, written representation of a Holder or transferee,
  certificate of auditors or any other certificate, statement, instrument,
  opinion, report, notice, request, consent, order, appraisal, bond or other
  paper or document believed by it to be genuine and to have been signed or
  presented by the proper party or parties;
 
    (ii) if (A) in performing its duties under this Trust Agreement the
  Property Trustee is required to decide between alternative courses of
  action, or (B) in construing any of the provisions in this Trust Agreement
  the Property Trustee finds the same ambiguous or inconsistent with any
  other provisions contained herein, or (C) the Property Trustee is unsure of
  the application of any provision of this Trust Agreement, then, except as
  to any matter as to which the Preferred Securityholders are entitled to
  vote under the terms of this Trust Agreement, the Property Trustee shall
  deliver a notice to the Depositor requesting written instructions of the
  Depositor as to the course of action to be taken. The Property Trustee
  shall take such action, or refrain from taking such action, as the Property
  Trustee shall be instructed in writing to take, or to refrain from taking,
  by the Depositor; provided, however, that if the Property Trustee does not
  receive such instructions of the Depositor within ten Business Days after
  it has delivered such notice, or such reasonably shorter period of time set
  forth in such notice (which to the extent practicable shall not be less
  than two Business Days), it may, but shall be under no duty to, take
 
                                       29
<PAGE>
 
  or refrain from taking such action not inconsistent with this Trust
  Agreement as it shall deem advisable and in the best interests of the
  Securityholders, in which event the Property Trustee shall have no
  liability except for its own bad faith, negligence or willful misconduct;
 
    (iii) the Property Trustee may consult with counsel of its selection and
  the written advice of such counsel or any Opinion of Counsel shall be full
  and complete authorization and protection in respect of any action taken,
  suffered or omitted by it hereunder in good faith and in reliance thereon;
 
    (iv) the Property Trustee shall be under no obligation to exercise any of
  the rights or powers vested in it by this Trust Agreement as the request or
  direction of any of the Securityholders pursuant to this Trust Agreement,
  unless such Securityholders shall have offered to the Property Trustee
  reasonable security or indemnity against the costs, expenses and
  liabilities which might be incurred by it in compliance with such request
  or direction;
 
    (v) the Property Trustee shall not be bound to make any investigation
  into the facts or matters stated in any resolution, certificate, statement,
  instrument, opinion, report, notice, request, consent, order, approval,
  bond or other document, unless requested in writing to do so by one or more
  Securityholders; and
 
    (vi) the Property Trustee may execute any of the trusts or powers
  hereunder or perform any duties hereunder either directly or by or through
  its agents or attorneys, provided that the Property Trustee shall be
  responsible for its own negligence or recklessness with respect to
  selection of any agent or attorney appointed by it hereunder.
 
  Section 8.04 Not Responsible for Recitals or Issuance of Securities. The
recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness. The Trustees shall not be accountable for
the use or application by the Trust of the proceeds of the Trust Securities in
accordance with Section 2.05.
 
  The Property Trustee may conclusively assume that any funds held by it
hereunder are legally available unless an officer of the Property Trustee
assigned to its Corporate Trustee Administrative Department shall have received
written notice from the Corporation, any Holder or any other Trustee that such
funds are not legally available.
 
  Section 8.05 May Hold Securities. Except as provided in the definition of the
term "Outstanding" in Article I, any Trustee or any other agent of the Trustees
or the Trust, in its individual or any other capacity, may become the owner or
pledgee of Trust Securities and may otherwise deal with the Trust with the same
rights it would have if it were not a Trustee or such other agent.
 
  Section 8.06 Compensation; Fees; Indemnity.
 
  The Depositor agrees:
 
    (1) to pay to the Trustees from time to time reasonable compensation for
  all services rendered by the Trustees hereunder (which compensation shall
  not be limited by any provision of law in regard to the compensation of a
  trustee of an express trust);
 
                                       30
<PAGE>
 
    (2) except as otherwise expressly provided herein, to reimburse the
  Trustees upon request for all reasonable expenses, disbursements and
  advances incurred or made by the Trustees in accordance with any provision
  of this Trust Agreement (including the reasonable compensation and the
  expenses and disbursements of their agents and counsel), except any such
  expense, disbursement or advance as may be attributable to their
  negligence, willful misconduct or bad faith; and
 
    (3) to indemnify the Trustees for, and to hold the Trustees harmless
  against, any and all loss, damage, claims, liability or expense incurred
  without negligence, willful misconduct or bad faith on their part, arising
  out of or in connection with the acceptance or administration of this Trust
  Agreement, including the costs and expenses of defending themselves against
  any claim or liability in connection with the exercise or performance of
  any of its powers or duties hereunder.
 
  The provisions of this Section 8.06 shall survive the termination of this
Trust Agreement.
 
  Section 8.07 Trustees Required; Eligibility.
 
  (a) There shall at all times be a Property Trustee hereunder with respect to
the Trust Securities. The Property Trustee shall be a Person that has a
combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Property Trustee with
respect to the Trust Securities shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article.
 
  (b) There shall at all times be one or more Administrative Trustees hereunder
with respect to the Trust Securities. Each Administrative Trustee shall be
either a natural person who is at least 21 years of age or a legal entity that
shall act through one or more persons authorized to bind such entity.
 
  (c) There shall at all times be a Delaware Trustee with respect to the Trust
Securities. The Delaware Trustee shall either be (i) a natural person who is at
least 21 years of age and a resident of the State of Delaware or (ii) a legal
entity authorized to conduct a trust business and with its principal place of
business in the State of Delaware that shall act through one or more persons
authorized to bind such entity.
 
  Section 8.08 Conflicting Interests.
 
  If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. To the extent permitted by the Trust Indenture Act, the Property
Trustee shall not be deemed to have a conflicting interest by virtue of being
trustee under the Guarantee, the Guarantee Agreement dated as of December 8,
1997, between the Depositor, as guarantor, and The Chase Manhattan Bank, as
trustee, and the Amended and Restated Trust Agreement dated as of December
 
                                       31
<PAGE>

Delaware trustee, Robert T. Lucas III and S.L. Love, as administrative
trustees, and The Chase Manhattan Bank, as property trustee.
 
  Section 8.09 Co-Property Trustees and Separate Trustee.
 
  At any time or times, for the purpose of meeting the legal requirements of
the Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Holder of the Common Securities and
the Property Trustee shall have power to appoint, and upon the written request
of the Property Trustee, the Depositor shall for such purpose join with the
Property Trustee in the execution, delivery and performance of all instruments
and agreements necessary or proper to appoint, one or more Persons approved by
the Property Trustee either to act as co-property trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to act as
separate trustee of any such Trust Property, in either case with such powers as
may be provided in the instrument of appointment, and to vest in such Person or
Persons in the capacity aforesaid, any property, title, right or power deemed
necessary or desirable, subject to the other provisions of this Section. If the
Depositor does not join in such appointment within 15 days after the receipt by
it of a request so to do, or in case an Indenture Event of Default has occurred
and is continuing, the Property Trustee alone shall have power to make such
appointment. Any co-property trustee or separate trustee appointed pursuant to
this Section shall satisfy the requirements of Section 8.07.
 
  Should any written instrument from the Depositor be required by any co-
property trustee or separate trustee so appointed for more fully confirming to
such co-property trustee or separate trustee such property, title, right, or
power, any and all such instruments shall, on request, be executed,
acknowledged, and delivered by the Depositor.
 
  Every co-property trustee or separate trustee shall, to the extent permitted
by law, but to such extent only, be appointed subject to the following terms,
namely:
 
    (i) The Trust Securities shall be executed, authenticated and delivered
  and all rights, powers, duties, and obligations hereunder in respect of the
  custody of securities, cash and other personal property held by, or
  required to be deposited or pledged with, the Trustees hereunder, shall be
  exercised, solely by the Trustees.
 
    (ii) The rights, powers, duties, and obligations hereby conferred or
  imposed upon the Property Trustee in respect of any property covered by
  such appointment shall be conferred or imposed upon and exercised or
  performed by the Property Trustee or by the Property Trustee and such co-
  property trustee or separate trustee jointly, as shall be provided in the
  instrument appointing such co-property trustee or separate trustee, except
  to the extent that under any law of any jurisdiction in which any
  particular act is to be performed, the Property Trustee shall be
  incompetent or unqualified to perform such act, in which event such rights,
  powers, duties, and obligations shall be exercised and performed by such
  co-property trustee or separate trustee.
 
    (iii) The Property Trustee at any time, by an instrument in writing
  executed by it, with the written concurrence of the Depositor, may accept
  the resignation of or remove any co-property trustee or separate trustee
  appointed under this Section, and, in case an Indenture Event of Default
  has occurred and is continuing, the Property Trustee shall have power to
  accept the resignation of, or remove, any such co-property trustee or
  separate trustee without the
 
                                       32
<PAGE>
 
  concurrence of the Depositor. Upon the written request of the Property
  Trustee, the Depositor shall join with the Property Trustee in the
  execution, delivery, and performance of all instruments and agreements
  necessary or proper to effectuate such resignation or removal. A successor
  to any co-property trustee or separate trustee so resigned or removed may
  be appointed in the manner provided in this Section.
 
    (iv) No co-property trustee or separate trustee hereunder shall be
  personally liable by reason of any act or omission of the Property Trustee,
  or any other such trustee hereunder.
 
    (v) The Trustees shall not be liable by reason of any act of a co-
  property trustee or separate trustee.
 
    (vi) Any Act of Holders delivered to the Property Trustee shall be deemed
  to have been delivered to each such co-property trustee and separate
  trustee.
 
  Section 8.10 Resignation and Removal; Appointment of Successor. No
resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.
 
  Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Holders. If the
instrument of acceptance by the successor Trustee required by Section 8.11
shall not have been delivered to the Relevant Trustee within 30 days after the
giving of such notice of resignation, the resigning Relevant Trustee may
petition, at the expense of the Trust, any court of competent jurisdiction for
the appointment of a successor Relevant Trustee.
 
  Unless an Indenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by Act of the Holder of the Common
Securities. If an Indenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Holder of the Common Securities at any time. In no event will
the Holders of the Preferred Securities have a right to vote to appoint, remove
or replace the Administrative Trustees.
 
  If any Trustee shall resign, be removed or become incapable of continuing to
act as Trustee, or if a vacancy shall occur in the office of any Trustee for
any reason, at a time when no Indenture Event of Default shall have occurred
and be continuing, the Holder of the Common Securities, by Act of the Holder of
the Common Securities, shall promptly appoint a successor Trustee or successor
Trustees, and the retiring Trustee shall comply with the applicable
requirements of Section 8.11. If the Property Trustee or the Delaware Trustee
shall resign, be removed or become incapable of continuing to act as the
Property Trustee or the Delaware Trustee, as the case may be, or a vacancy
shall occur in the office of any such Trustee for any reason, at a time when an
Indenture Event of Default shall have occurred and be continuing, the Holders
of Preferred Securities, by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities then Outstanding, shall promptly appoint a
successor Relevant Trustee or Relevant Trustees and such successor Relevant
Trustee or Relevant Trustees shall comply with the applicable requirements of
Section 8.11. If an
 
                                       33
<PAGE>
 
Administrative Trustee shall resign, be removed or become incapable of acting
as Administrative Trustee, or a vacancy shall occur in the office of any such
Trustee for any reason, at a time when an Indenture Event of Default shall have
occurred and be continuing, the Holder of the Common Securities, by Act of the
Holder of the Common Securities, shall promptly appoint a successor
Administrative Trustee or Administrative Trustees and such successor
Administrative Trustee or Administrative Trustees shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee shall
have been so appointed in accordance with this Section 8.10 and accepted
appointment in the manner required by Section 8.11, any Holder who has been a
Holder of Trust Securities for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor Relevant Trustee.
 
  The Property Trustee shall give notice of each resignation and each removal
of a Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 10.08 and shall give notice to the Depositor. Each
notice shall include the name of the successor Relevant Trustee and the address
of its Corporate Trust Office if it is the Property Trustee.
 
  Notwithstanding the foregoing or any other provision of this Trust Agreement,
in the event any Administrative Trustee or a Delaware Trustee who is a natural
person dies or becomes, in the opinion of the Depositor, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (i) the act of the remaining Administrative Trustee or (ii)
otherwise by the Depositor (with the successor in each case being a Person who
satisfies the eligibility requirements for an Administrative Trustee or a
Delaware Trustee, as the case may be, set forth in Section 8.07).
 
  Section 8.11 Acceptance of Appointment by Successor. In case of the
appointment hereunder of a successor Relevant Trustee, every such successor
Relevant Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Relevant Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Relevant
Trustee shall become effective and such successor Relevant Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Relevant Trustee; but, on the request
of the Depositor or the successor Relevant Trustee, such retiring Relevant
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Relevant Trustee all the rights, powers and
trusts of the retiring Relevant Trustee and shall duly assign, transfer and
deliver to such successor Relevant Trustee all property and money held by such
retiring Relevant Trustee hereunder.
 
  Upon request of any such successor Relevant Trustee, the Trust shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Relevant Trustee all such rights, powers and trusts referred
to in the preceding paragraph.
 
  No successor Relevant Trustee shall accept its appointment unless at the time
of such acceptance such successor Relevant Trustee shall be qualified and
eligible under this Article.
 
  Section 8.12 Merger, Conversion, Consolidation or Succession to Business. Any
Person into which the Property Trustee, Delaware Trustee or any Administrative
Trustee which is not a natural person may be merged or converted or with which
it may be consolidated, or any Person resulting
 
                                       34
<PAGE>
 
from any merger, conversion or consolidation to which such Relevant Trustee
shall be a party, or any Person succeeding to all or substantially all the
corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided such Person shall be otherwise
qualified and eligible, without the execution or filing of any paper or any
further act on the part of any of the parties hereto.
 
  Section 8.13 Preferential Collection of Claims Against Depositor or Trust. If
and when the Property Trustee shall be or become a creditor of the Depositor or
the Trust (or any other obligor upon the Junior Subordinated Notes or the Trust
Securities), the Property Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Depositor or
Trust (or any such other obligor). For purposes of Sections 311(b)(4) and (6)
of the Trust Indenture Act:
 
    (a) "cash transaction" means any transaction in which full payment for
  goods or securities sold is made within seven days after delivery of the
  goods or securities in currency or in checks or other orders drawn upon
  banks or bankers and payable upon demand; and
 
    (b) "self-liquidating paper" means any draft, bill of exchange,
  acceptance or obligation which is made, drawn, negotiated or incurred by
  the Depositor or the Trust (or any such obligor) for the purpose of
  financing the purchase, processing, manufacturing, shipment, storage or
  sale of goods, wares or merchandise and which is secured by documents
  evidencing title to, possession of, or a lien upon, the goods, wares or
  merchandise or the receivables or proceeds arising from the sale of the
  goods, wares or merchandise previously constituting the security, provided
  the security is received by the Property Trustee simultaneously with the
  creation of the creditor relationship with the Depositor or the Trust (or
  any such obligor) arising from the making, drawing, negotiating or
  incurring of the draft, bill of exchange, acceptance or obligation.
 
  Section 8.14 Reports by Property Trustee.
 
  (a) Within 60 days after October 1 of each year commencing with October 1,
  , if required by Section 313(a) of the Trust Indenture Act, the Property
Trustee shall transmit a brief report dated as of such October 1 with respect
to any of the events specified in such Section 313(a) that may have occurred
since the later of the date of this Trust Agreement or the preceding October 1.
 
  (b) The Property Trustee shall transmit to Securityholders the reports
required by Section 313(b) of the Trust Indenture Act at the times specified
therein.

to the Persons required by Sections 313(c) and (d) of the Trust Indenture Act.
 
  Section 8.15 Reports to the Property Trustee. The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information as required by Section 314 of
the Trust Indenture Act (if any) and, within 120 days after the end of each
fiscal year of the Depositor, the compliance certificate required by Section
314(a)(4) of the Trust Indenture Act in the form and in the manner required by
Section 314 of the Trust Indenture Act.
 
                                       35
<PAGE>
 
  Section 8.16 Evidence of Compliance with Conditions Precedent. Each of the
Depositor and the Administrative Trustees on behalf of the Trust shall provide
to the Property Trustee such evidence of compliance with any conditions
precedent, if any, provided for in this Trust Agreement that relate to any of
the matters set forth in Section 314(c) of the Trust Indenture Act. Any
certificate or opinion required to be given pursuant to Section 314(c)(1) of
the Trust Indenture Act shall comply with Section 314(e) of the Trust Indenture
Act.
 
  Section 8.17 Number of Trustees.
 
  (a) The number of Trustees shall initially be four, provided that the
Depositor by written instrument may increase or decrease the number of
Administrative Trustees.
 
  (b) If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the
number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.
 
  (c) The death, resignation, retirement, removal, bankruptcy, incompetence or
incapacity to perform the duties of a Trustee shall not operate to annul the
Trust. Whenever a vacancy in the number of Administrative Trustees shall occur,
until such vacancy is filled by the appointment of an Administrative Trustee in
accordance with Section 8.10, the Administrative Trustees in office, regardless
of their number (and notwithstanding any other provision of this Trust
Agreement), shall have all powers granted to the Administrative Trustees and
shall discharge the duties imposed upon the Administrative Trustees by this
Trust Agreement.
 
  Section 8.18 Delegation of Power.
 
  (a) Any Administrative Trustee, may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any documents contemplated in Section
2.07(A), including any registration statement or amendment thereto filed with
the Commission, or making any other governmental filing; and
 
  (b) The Administrative Trustees shall have power to delegate from time to
time to such of their number the doing of such things and the execution of such
instruments either in name of the Trust or the names of the Administrative
Trustees or otherwise as the Administrative Trustees may deem expedient, to the
extent such delegation is not prohibited by applicable law or contrary to the
provisions of the Trust, as set forth herein.
 
  Section 8.19 Enforcement of Rights of Property Trustee by Securityholders. If
an Indenture Event of Default occurs and is continuing, then (i) the Holders of
Preferred Securities will rely on the enforcement by the Property Trustee of
its rights against the Corporation as the holder of the Junior Subordinated
Notes and (ii) the Holders of a majority in aggregate Liquidation Amount 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 trust or power conferred upon the Property
Trustee under this Trust Agreement, including the right to direct the Property
Trustee to exercise the remedies available to it as a holder of the Junior
Subordinated Notes, provided that such direction shall not be in conflict with
any rule of law or with this Trust
 
                                       36

Agreement, and could not involve the Property Trustee in personal liability in
circumstances where reasonable indemnity would not be adequate. If the Property
Trustee fails to enforce its rights under the Junior Subordinated Notes, a
Holder of Preferred Securities may, to the extent permitted by applicable law,
institute a legal proceeding against the Corporation to enforce its rights
under this Trust Agreement without first instituting any legal proceeding
against the Property Trustee or any other Person, including the Trust; it being
understood and intended that no one or more of such Holders shall have any
right in any manner whatsoever by virtue of, or by availing of, any provision
of this Trust Agreement to affect, disturb or prejudice the rights of any other
of such Holders or to obtain or to seek to obtain priority or preference over
any other of such Holders or to enforce any right under this Trust Agreement,
except in the manner herein provided and for the equal and ratable benefit of
all such Holders. Notwithstanding the foregoing, a Holder of Preferred
Securities may institute a legal proceeding directly against the Corporation
without first instituting a legal proceeding against or requesting or directing
that action be taken by the Property Trustee or any other Person, for
enforcement of payment to such Holder of principal of or interest on the Junior
Subordinated Notes having a principal amount equal to the aggregate stated
Liquidation Amount of the Preferred Securities of such Holder on or after the
due dates therefor specified or provided for in the Junior Subordinated Notes.
The Corporation shall be subrogated to all rights of the Holders of Preferred
Securities in respect of any amounts paid to such Holders by the Corporation
pursuant to this Section.
 
  Section 8.20 Delaware Trustee.
 
  (a) Notwithstanding any other provision of this Trust Agreement, the Delaware
Trustee shall not be entitled to exercise any powers, nor shall the Delaware
Trustee have any of the duties and responsibilities, of the Administrative
Trustees or the Property Trustee described in this Trust Agreement. The
Delaware Trustee shall be a trustee for the sole and limited purpose of
fulfilling the requirements of (S)3807 of the Delaware Business Trust Act.
 
  (b) It is expressly understood and agreed by the parties hereto that in
fulfilling its obligations as Delaware Trustee hereunder on behalf of the Trust
(i) any agreements or instruments executed and delivered by Chase Manhattan
Bank Delaware are executed and delivered not in its individual capacity but
solely as Delaware Trustee under this Trust Agreement in the exercise of the
powers and authority conferred and vested in it, (ii) each of the
representations, undertakings and agreements herein made on the part of the
Trust is made and intended not as representations, warranties, covenants,
undertakings and agreements by Chase Manhattan Bank Delaware in its individual
capacity but is made and intended for the purpose of binding only the Trust,
and (iii) under no circumstances shall Chase Manhattan Bank Delaware in its
individual capacity be personally liable for the payment of any indebtedness or
expenses of the Trust or be liable for the breach or failure of any obligation,
representation, warranty or covenant made or undertaken by the Trust under this
Trust Agreement, except if such breach or failure is due to any gross
negligence or willful misconduct of Chase Manhattan Bank Delaware as the
Delaware Trustee.

payment of the Trust Securities; (b) the payment of any expenses owed by the

occurs, the Trust shall be liquidated and the Property Trustee shall distribute
the Junior Subordinated Notes to the Securityholders as provided in this
Section 9.04.
 
  (b) In connection with a distribution of the Junior Subordinated Notes, each
Holder of Trust Securities shall be entitled to receive, after the satisfaction
of liabilities to creditors of the Trust (as evidenced by a certificate of the
Administrative Trustees), a Like Amount of Junior Subordinated Notes. Notice of
liquidation shall be given by the Trustees by first-class mail, postage
prepaid, mailed not later than 30 nor more than 60 days prior to the
Liquidation Date to each Holder of Trust Securities at such Holder's address
appearing in the Security Register. All notices of liquidation shall:
 
    (i) state the Liquidation Date;
 
    (ii) state that from and after the Liquidation Date, the Trust Securities
  will no longer be deemed to be Outstanding and any Trust Securities
  Certificates not surrendered for exchange will be deemed to represent a
  Like Amount of Junior Subordinated Notes; and
 
                                       38
<PAGE>
 
    (iii) provide such information with respect to the mechanics by which
  Holders may exchange Trust Securities Certificates for Junior Subordinated
  Notes as the Administrative Trustees or the Property Trustee shall deem
  appropriate.
 
  (c) In order to effect the liquidation of the Trust and distribution of the
Junior Subordinated Notes to Securityholders, the Property Trustee shall
establish a record date for such distribution (which shall be not more than 45
days prior to the Liquidation Date) and, either itself acting as exchange agent
or through the appointment of a separate exchange agent, shall establish such
procedures as it shall deem appropriate to effect the distribution of Junior
Subordinated Notes in exchange for the Outstanding Trust Securities
Certificates.
 
  (d) After the Liquidation Date, (i) the Trust Securities will no longer be
deemed to be Outstanding, (ii) certificates representing a Like Amount of
Junior Subordinated Notes will be issued to Holders of Trust Securities
Certificates, upon surrender of such certificates to the Administrative
Trustees or their agent for exchange, (iii) any Trust Securities Certificates
not so surrendered for exchange will be deemed to represent a Like Amount of
Junior Subordinated Notes, accruing interest at the rate provided for in the
Junior Subordinated Notes from the last Distribution Date on which a
Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so
surrendered, no payments of interest or principal will be made to Holders of
Trust Securities Certificates with respect to such Junior Subordinated Notes)
and (iv) all rights of Securityholders holding Trust Securities will cease,
except the right of such Securityholders to receive Junior Subordinated Notes
upon surrender of Trust Securities Certificates.
 
  (e) The Depositor will use its best efforts to have the Junior Subordinated
Notes that are distributed in exchange for the Preferred Securities to be
listed on such securities exchange as the Preferred Securities are then listed.
The Depositor may elect to have the Junior Subordinated Notes issued in book-
entry form to the Clearing Agency or its nominee pursuant to the Certificate
Depository Agreement.
 
  Section 9.05 Bankruptcy. If an Early Termination Event specified in clause
(i) of Section 9.02 has occurred, the Trust shall be liquidated. The Property
Trustee shall distribute the Junior Subordinated Notes to the Securityholders
as provided in Section 9.04, unless such distribution is determined by the
Administrative Trustees not to be practical, in which event the Holders will be
entitled to receive out of the assets of the Trust available for distribution
to Securityholders, after satisfaction of liabilities to creditors, an amount
equal to the Liquidation Amount per Trust Security plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If such Liquidation Distribution can be paid only
in part because the Trust has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Trust on the Trust Securities shall be
paid on a pro rata basis (based upon Liquidation Amounts). The Holder of the
Common Securities will be entitled to receive Liquidation Distributions upon
any such dissolution, winding-up or termination pro rata (determined as
aforesaid) with Holders of Preferred Securities, except that, if an Indenture
Event of Default has occurred and is continuing, the Preferred Securities shall
have a priority over the Common Securities.

enforceable by, all such Beneficiaries, whether or not such Beneficiaries have
received notice hereof.
 
  Section 10.02 Limitation of Rights of Securityholders. The death or
incapacity of any Person having an interest, beneficial or otherwise, in a

otherwise affect the rights, obligations and liabilities of the parties hereto

to matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement, provided,
however, that any such amendment shall not adversely affect in any material
respect the interests of any Securityholder, (ii) to modify, eliminate or add
to any provisions of this Trust Agreement to such extent as shall be necessary

Securities are outstanding; provided, however, that, in the case of clause (i),
any amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders or (iii) to provide the Property
Trustee with the authority to authenticate on behalf of the Administrative

consent of Securityholders representing not less than 66 2/3% (based upon
Liquidation Amounts) of the Trust Securities then Outstanding and (ii) receipt
by the Trustees of an Opinion of Counsel to the effect that such amendment or
the exercise of any power granted to the Trustees in accordance with such

States federal income tax purposes or the Trust's exemption from status of an
"investment company" under the Investment Company Act.
 
  (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent
being obtained in accordance with Section 6.03

as of a specified date, (ii) restrict the right of a Securityholder to
institute suit for the enforcement of any such payment on or after such date,
(iii) change the purpose of the Trust, (iv) authorize the issuance of any
additional beneficial interests in the Trust, or (v) change the consent
required pursuant to this Section 10.03.

Trustees shall not enter into or consent to any amendment to this Trust
Agreement which would cause the Trust to fail or cease to qualify for the
exemption from status of an "investment company" under the Investment Company
Act of 1940, as amended, afforded by Rule 3a-5 thereunder.
 
  (e) Without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

shall be entitled to receive, and (subject to Section 8.01) shall be fully
protected in relying upon an Opinion of Counsel stating that the execution of
such amendment is authorized or permitted by this Trust Agreement. Any Trustee
may, but shall not be obligated to, enter into any such amendment which affects
such Trustee's own rights, duties, immunities or liabilities under this Trust
Agreement or otherwise.

Administrative Trustees shall promptly provide to the Depositor a copy of such
amendment.

in the Trust Securities Certificates shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

  (a) This Guarantee Agreement shall be held by the Trustee for the benefit of
the Holders, and the Trustee shall not transfer this Guarantee Agreement to any
Person unless the Trustee shall assign rights hereunder to a Holder to the
extent such assignment is necessary to exercise such Holder's rights pursuant
to Section 5.04 or to a Successor Trustee upon acceptance by such Successor

undertake to perform only such duties as are specifically set forth in this
Guarantee Agreement, and no implied covenants shall be read into this Guarantee
Agreement against the Trustee. In case an Event of Default has occurred (that
has not been cured or waived pursuant to Section 2.06), the Trustee shall
exercise such of the rights and powers vested in it by this Guarantee
Agreement, and use the same degree of care and skill in its exercise thereof,
as a prudent person would exercise or use under the circumstances in the
conduct of his or her own affairs.
 
  (d) No provision of this Guarantee Agreement shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:
 
    (i) prior to the occurrence of any Event of Default and after the curing
  or waiving of all such Events of Default that may have occurred:
 
      (A) the duties and obligations of the Trustee shall be determined
    solely by the express provisions of this Guarantee Agreement, and the
    Trustee shall not be liable except for the
 
                                       5

    performance of such duties and obligations as are specifically set
    forth in this Guarantee Agreement; and
 
      (B) in the absence of bad faith on the part of the Trustee, the
    Trustee may conclusively rely, as to the truth of the statements and
    the correctness of the opinions expressed therein, upon any
    certificates or opinions furnished to the Trustee and conforming to the
    requirements of this Guarantee Agreement; but in the case of any such
    certificates or opinions that by any provision hereof are specifically
    required to be furnished to the Trustee, the Trustee shall be under a
    duty to examine the same to determine whether or not they conform to
    the requirements of this Guarantee Agreement;

  good faith by a Responsible Officer of the Trustee, unless it shall be
  proved that the Trustee was negligent in ascertaining the pertinent facts
  upon which such judgment was made;
 
    (iii) the Trustee shall not be liable with respect to any action taken or
  omitted to be taken by it in good faith in accordance with the direction of
  the Holders of a Majority in liquidation amount of the Preferred Securities
  relating to the time, method and place of conducting any proceeding for any
  remedy available to the Trustee, or exercising any trust or power conferred
  upon the Trustee under this Guarantee Agreement; and
 
    (iv) no provision of this Guarantee Agreement shall require the Trustee
  to expend or risk its own funds or otherwise incur personal financial
  liability in the performance of any of its duties or in the exercise of any
  of its rights or powers, if the Trustee shall have reasonable grounds for
  believing that the repayment of such funds or liability is not reasonably
  assured to it under the terms of this Guarantee Agreement or adequate
  indemnity against such risk or liability is not reasonably assured to it.
 
  Section 3.02. Certain Rights of Trustee.
 
  (a) Subject to the provisions of Section 3.01:
 
    (i) the Trustee may rely and shall be fully protected in acting or

  document believed by it to be genuine and to have been signed, sent or
  presented by the proper party or parties;
 
    (ii) any direction or act of the Guarantor contemplated by this Guarantee
  Agreement shall be sufficiently evidenced by an Officers' Certificate;
 
    (iii) whenever, in the administration of this Guarantee Agreement, the

  Certificate which, upon receipt of such request, shall be promptly
  delivered by the Guarantor;

  with such advice or opinion; such counsel may be counsel to the Guarantor
  or any
 
                                       6

  administration of this Guarantee Agreement from any court of competent
  jurisdiction;
 
    (v) the Trustee shall be under no obligation to exercise any of the

  person in the position of the Trustee, against the costs, expenses
  (including attorneys' fees and expenses) and liabilities that might be
  incurred by it in complying with such request or direction, including such
  reasonable advances as may be requested by the Trustee; provided that

  Trustee, upon the occurrence of an Event of Default, of its obligation to
  exercise the rights and powers vested in it by this Guarantee Agreement;
 
    (vi) the Trustee shall not be bound to make any investigation into the
  facts or matters stated in any resolution, certificate, statement,
  instrument, opinion, report, notice, request, direction, consent, order,
  bond, debenture, note, other evidence of indebtedness or other paper or
  document, but the Trustee, in its discretion, may make such further inquiry
  or investigation into such facts or matters as it may see fit;
 
    (vii) the Trustee may execute any of the trusts or powers hereunder or
  perform any duties hereunder either directly or by or through agents or

  it hereunder; and
 
    (viii) whenever in the administration of this Guarantee Agreement the
  Trustee shall deem it desirable to receive instructions with respect to
  enforcing any remedy or right or taking any other action hereunder, the
  Trustee (i) may request instructions from the Holders, (ii) may refrain
  from enforcing such remedy or right or taking such other action until such
  instructions are received, and (iii) shall be protected in acting in
  accordance with such instructions.
 
  (b) No provision of this Guarantee Agreement shall be deemed to impose any
duty or obligation on the Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it in any jurisdiction
in which it shall be illegal, or in which the Trustee shall be unqualified or
incompetent in accordance with applicable law, to perform any such act or acts
or to exercise any such right, power, duty or obligation. No permissive power
or authority available to the Trustee shall be construed to be a duty.
 
  Section 3.03. Compensation; Fees; Indemnity.
 
  The Guarantor agrees:
 
    (a) to pay to the Trustee from time to time reasonable compensation for
  all services rendered by the Trustee hereunder (which compensation shall
  not be limited by any provision of law in regard to the compensation of a
  trustee of an express trust);
 
    (b) except as otherwise expressly provided herein, to reimburse the
  Trustee upon request for all reasonable expenses, disbursements and
  advances incurred or made by the Trustee in accordance with any provision

  or any of the assets of the Trust;
 
    (e) any invalidity of, or defect or deficiency in, the Preferred
  Securities;
 
    (f) the settlement or compromise of any obligation guaranteed hereby or
  hereby incurred; or
 
    (g) any other circumstance whatsoever that might otherwise constitute a
  legal or equitable discharge or defense of a guarantor, it being the intent
  of this Section 5.03 that the obligations of the Guarantor hereunder shall
  be absolute and unconditional under any and all circumstances.
 
  There shall be no obligation of the Holders to give notice to, or obtain
consent of, the Guarantor with respect to the happening of any of the
foregoing.
 
  Section 5.04. Rights of Holders. The Guarantor expressly acknowledges that:
(i) this Guarantee Agreement will be deposited with the Trustee to be held for
the benefit of the Holders; (ii) the Trustee has the right to enforce this
Guarantee Agreement on behalf of the Holders; (iii) the Holders of a Majority
in liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee in respect of this Guarantee Agreement or to direct the exercise of
any trust or power conferred upon the Trustee under this Guarantee Agreement,
provided that such direction shall not be in conflict with any rule of law or
with this Guarantee Agreement, and could not involve the Trustee in personal
liability in circumstances where reasonable indemnity would not be adequate;
and (iv) any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee Agreement, without first
instituting a legal proceeding against or requesting or directing that action
be taken by the Trustee or any other person; it being understood and intended
that no one or more of such Holders shall have any right in any manner
whatsoever by virtue of, or by availing of, any provision of this Guarantee
Agreement to affect, disturb or prejudice the rights of any other of such
Holders or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Guarantee Agreement, except
in the manner herein provided and for the equal and ratable benefit of all of
such Holders.
 
  Section 5.05. Guarantee of Payment. This Guarantee Agreement creates a
guarantee of payment and not of collection. This Guarantee Agreement will not
be discharged except by payment of the Guarantee Payments in full (without
duplication) or upon the distribution of Junior Subordinated Notes to the
Holders in exchange for all of the Preferred Securities.
 
  Section 5.06. Subrogation. The Guarantor shall be subrogated to all (if any)
rights of the Holders against the Trust in respect of any amounts paid to the
Holders by the Guarantor under this Guarantee Agreement; provided, however,
that the Guarantor shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee Agreement,
if, at the time of any such payment, any amounts of Guarantee Payments are due
and unpaid under this Guarantee Agreement. If any amount shall be
 
                                       10
<PAGE>
 
paid to the Guarantor in violation of the preceding sentence, the Guarantor
agrees to hold such amount in trust for the Holders and to pay over such amount
to the Holders.
 
  Section 5.07. Independent Obligations. The Guarantor acknowledges that its
obligations hereunder are independent of the obligations of the Trust with
respect to the Preferred Securities and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03 hereof.
 
                                   ARTICLE VI
 
                                 Subordination
 
  Section 6.01. Subordination. This Guarantee Agreement will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to all other liabilities of the Guarantor, including the
Junior Subordinated Notes, except those obligations or liabilities made pari
passu or subordinate by their terms, (ii) pari passu with the preferred stock
or preferred stock A now or hereafter issued by the Guarantor, and (iii) senior
to all common stock of the Guarantor. This Guarantee Agreement ranks pari passu
with each other substantially similar guarantee agreement entered into by the
Guarantor in respect of trust or other preferred securities issued by an
Affiliate of the Guarantor.
 
                                  ARTICLE VII
 
                                  Termination
 
  Section 7.01. Termination. This Guarantee Agreement shall terminate and be of
no further force and effect upon: (i) full payment of the Redemption Price of
all Preferred Securities, (ii) the distribution of Junior Subordinated Notes to
the Holders in exchange for all of the Preferred Securities, or (iii) full
payment of the amounts payable in accordance with the Trust Agreement upon
liquidation of the Trust. Notwithstanding the foregoing, this Guarantee
Agreement will continue to be effective or will be reinstated, as the case may
be, if at any time any Holder must restore payment of any sums paid with
respect to Preferred Securities or under this Guarantee Agreement.
 
                                  ARTICLE VIII
 
                                 Miscellaneous
 
  Section 8.01. Successors and Assigns. All guarantees and agreements contained
in this Guarantee Agreement shall bind the successors, assigns, receivers,
trustees and representatives of the Guarantor and shall inure to the benefit of
the Holders then outstanding. Except in connection with a consolidation,
merger, conveyance, transfer, or lease involving the Guarantor that is
permitted under Article Eight of the Indenture, the Guarantor shall not assign
its obligations hereunder.
 
  Section 8.02. Amendments. Except with respect to any changes which do not
materially and adversely affect the rights of Holders (in which case no consent
of Holders will be required), this Guarantee Agreement may only be amended with
the prior approval of the Holders of not less than 66 2/3% in liquidation
amount of all the outstanding Preferred Securities. The provisions of Article
Six of the Trust Agreement concerning meetings of Holders shall apply to the
giving of such approval.

          Re:  Registration Statement on Form S-3

Gentlemen:

          We are acting as counsel to Duke Energy Corporation ("Duke") in
connection with the preparation of a Registration Statement on Form S-3 (the
"Registration Statement"), including a preliminary prospectus and a preliminary
prospectus supplement, being filed today with the Securities and Exchange
Commission (the "Commission") for the registration under the Securities Act of
1933, as amended (the "Act"), of (1) Junior Subordinated Notes (the "Junior
Subordinated Notes") to be issued by Duke to Duke Energy Capital Trust II (the
"Trust"), (2) Trust Preferred Securities (liquidation amount $        per
Preferred Security) to be issued by the Trust and (3) Duke's Guarantee (as
defined in the Registration Statement) with respect to such Trust Preferred
Securities.  The Junior Subordinated Notes will be issued pursuant to the
Subordinated Indenture, dated as of December 1, 1997, as supplemented, between
Duke and the trustee named therein (the "Subordinated Indenture") and the
Guarantee will be issued pursuant to a guarantee agreement between Duke and the
trustee named therein (the "Guarantee Agreement"), in the form filed as an
exhibit to the Registration Statement.

          We are of the opinion that, upon compliance with the pertinent
provisions of the Act and the Trust Indenture Act of 1939, as amended, upon
receipt of appropriate authorizations from the North Carolina Utilities
Commission and The Public Service Commission of South Carolina, upon compliance
with applicable securities or blue sky laws of various jurisdictions and upon
the adoption of appropriate resolutions by the Board of Directors of Duke or a
duly authorized committee thereof, when an indenture supplemental to the
Subordinated Indenture and the Guarantee Agreement have been duly executed and
delivered by the proper officers of Duke and the trustees named therein, and
when the Junior Subordinated Notes and the Guarantee have been executed,
authenticated and delivered in accordance with the terms of such supplemental
indenture and the Guarantee Agreement, as the case may be, the Junior
Subordinated Notes and the Guarantee will be valid, binding and legal
obligations of Duke (subject to applicable bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally and to general principles of equity, whether
considered in a proceeding at law or in equity). In rendering the foregoing
opinion, we have relied on the opinion of Ellen T. Ruff, Esq. attached hereto as
Annex I with respect to matters of North Carolina law.

          The foregoing opinion is limited solely to the laws of the State of
New York and the Federal laws of the United States of America.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the statements with respect to our firm under the
caption "Validity of the Securities" in the preliminary prospectus and "Validity
of the Securities" in the preliminary prospectus supplement included in the
Registration Statement. In giving the foregoing consent, we do not thereby
admit that we come within the category of persons whose consent is required
under Section 7 of the Act or the rules and regulations of the Commission 
thereunder.

          Re:  Registration Statement on Form S-3

Gentlemen:

          We are acting as counsel to Duke Energy Corporation ("Duke") in
connection with the preparation of a Registration Statement on Form S-3 (the
"Registration Statement"), including a preliminary prospectus and a preliminary
prospectus supplement, being filed today with the Securities and Exchange
Commission (the "Commission") for the registration under the Securities Act of
1933, as amended (the "Act"), of (1) Junior Subordinated Notes (the "Junior
Subordinated Notes") to be issued by Duke to Duke Energy Capital Trust IV (the
"Trust"), (2) Trust Preferred Securities (liquidation amount $        per
Preferred Security) to be issued by the Trust and (3) Duke's Guarantee (as
defined in the Registration Statement) with respect to such Trust Preferred
Securities.  The Junior Subordinated Notes will be issued pursuant to the
Subordinated Indenture, dated as of December 1, 1997, as supplemented, between
Duke and the trustee named therein (the "Subordinated Indenture") and the
Guarantee will be issued pursuant to a guarantee agreement between Duke and the
trustee named therein (the "Guarantee Agreement"), in the form filed as an
exhibit to the Registration Statement.

          We are of the opinion that, upon compliance with the pertinent
provisions of the Act and the Trust Indenture Act of 1939, as amended, upon
receipt of appropriate authorizations from the North Carolina Utilities
Commission and The Public Service Commission of South Carolina, upon compliance
with applicable securities or blue sky laws of various jurisdictions and upon
the adoption of appropriate resolutions by the Board of Directors of Duke or a
duly authorized committee thereof, when an indenture supplemental to the
Subordinated Indenture and the Guarantee Agreement have been duly executed and
delivered by the proper officers of Duke and the trustees named therein, and
when the Junior Subordinated Notes and the Guarantee have been executed,
authenticated and delivered in accordance with the terms of such supplemental
indenture and the Guarantee Agreement, as the case may be, the Junior
Subordinated Notes and the Guarantee will be valid, binding and legal
obligations of Duke (subject to applicable bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally and to general principles of equity, whether
considered in a proceeding at law or in equity). In rendering the foregoing
opinion, we have relied on the opinion of Ellen T. Ruff, Esq. attached hereto as
Annex I with respect to matters of North Carolina law.
<PAGE>
 
          The foregoing opinion is limited solely to the laws of the State of
New York and the Federal laws of the United States of America.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the statements with respect to our firm under the
caption "Validity of the Securities" in the preliminary prospectus and "Validity
of the Securities" in the preliminary prospectus supplement included in the
Registration Statement. In giving the foregoing consent, we do not thereby admit
that we come within the category of persons whose consent is required under
Section 7 of the Act or the rules and regulations of the Commission thereunder.

          Re:  Duke Energy Capital Trust II

Ladies and Gentlemen:

          We have acted as special Delaware counsel for Duke Energy Corporation,
a North Carolina corporation (the "Company"), and Duke Energy Capital Trust II,
a Delaware business trust (the "Trust"), in connection with the matters set
forth herein.  At your request, this opinion is being furnished to you.

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a) The Certificate of Trust of the Trust, dated November 14, 1997 as
filed with the office of the Secretary of State of the State of Delaware (the
"Secretary of State") on November 14, 1997;

          (b) The Trust Agreement of the Trust, dated as of November 14, 1997
between the Company, as Depositor, and the trustee of the Trust named therein;

          (c) The Registration Statement (the "Registration Statement") on Form
S-3, including a preliminary prospectus (the "Prospectus") and a preliminary
prospectus supplement (the "Prospectus Supplement"), relating to the     % Trust
Preferred Securities of the Trust representing preferred undivided beneficial
interests in the assets of the Trust (each, a "Preferred Security" and
collectively, the "Preferred Securities"), filed by the Company, the Trust and
others as set forth therein with the Securities and Exchange Commission on May
21, 1999;

          (d) A form of Amended and Restated Trust Agreement for the Trust, to
be entered into between the Company, the trustees of the Trust named therein,
and the holders, from time to time, of undivided beneficial interests in the
assets of the Trust (including Exhibits C and E thereto) (the "Trust
Agreement"), attached as an exhibit to the Registration Statement; and

          (e) A Certificate of Good Standing for the Trust, dated May 21, 1999,
obtained from the Secretary of State.
<PAGE>
 
          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (e) above.  In particular,
we have not reviewed any document (other than the documents listed in paragraphs
(a) through (e) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

          For purposes of this opinion, we have assumed (i) that the Trust
Agreement and the Certificate of Trust are in full force and effect and have not
been amended, (ii) except to the extent provided in paragraph 1 below, the due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Preferred Security is to be issued by the Trust (collectively, the "Preferred
Security Holders") of a Preferred Security Certificate for such Preferred
Security and the payment for such Preferred Security, in accordance with the
Trust Agreement and the Registration Statement, and (vii) that the Preferred
Securities are issued and sold to the Preferred Security Holders in accordance
with the Trust Agreement and the Registration Statement.  We have not
participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

                                       2

<PAGE>
 
          2.  The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.  The Preferred Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Validity of the
Securities" in the Prospectus and "Validity of the Securities" in the Prospectus
Supplement.  In giving the foregoing consents, we do not thereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.  Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other person for any purpose.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

                                       2

          2.  The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.  The Preferred Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Validity of the
Securities" in the Prospectus and "Validity of the Securities" in the Prospectus
Supplement.  In giving the foregoing consents, we do not thereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.  Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other person for any purpose.

          Re:  Registration Statement on Form S-3

Gentlemen:

          We have acted as counsel to Duke Energy Corporation ("Duke"), Duke
Energy Capital Trust II, Duke Energy Capital Trust III and Duke Energy Capital
Trust IV (the "Trusts") in connection with the preparation of a Registration
Statement on Form S-3, including a preliminary prospectus and preliminary
prospectus supplement, being filed today with the Securities and Exchange
Commission (the "Commission") for the registration under the Securities Act of
1933 (the "Securities Act"), of (1) Junior Subordinated Notes (the "Junior
Subordinated Notes") to be issued by Duke to the Trusts, (2) Trust Preferred
Securities (liquidation amount $    per Preferred Security) to be issued by
the Trusts and (3) Duke's Guarantees (as defined in the Registration Statement)
with respect to such Trust Preferred Securities. The Trusts will be organized
pursuant to an amended and restated trust agreement between Duke and the
trustees named therein. The Junior Subordinated Notes will be issued pursuant to
the Subordinated Indenture, as supplemented, dated as of December 1, 1997,
between Duke and the trustee named therein and the Guarantees will be issued
pursuant to guarantee agreements between Duke and the trustee named therein, in
the form filed as an exhibit to the Registration Statement.

          On the basis and subject to the accuracy of the statements contained
in the materials referred to above, and our consideration of such other matters
as we have deemed necessary, it is our opinion that under current law the
material federal income tax consequences to holders of Trust Preferred
Securities issued by the Trusts will be as described under the heading "Material
Federal Income Tax Considerations" in the preliminary prospectus supplement
constituting part of the Registration Statement.  You have not requested, and we
do not express, an opinion concerning any other tax consequences of the issuance
by the Trusts of the Trust Preferred Securities.  This opinion is not to be
used, circulated, quoted or otherwise referred to for any purpose without our
express written permission.

          We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement and to the statements with respect to
our firm in the section captioned "Material Federal Income Tax Considerations"
in the preliminary prospectus

supplement constituting part of the Registration Statement. In giving the
foregoing consent, we do not thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission thereunder.

                                    Very truly yours,

                                    /s/ Dewey Ballantine LLP
