                                   WITNESSETH:

WHEREAS, the Company has heretofore entered into an Indenture, dated as of
August 16, 2000 (the "Original Indenture") with The Chase Manhattan Bank, as

WHEREAS, the Company proposes to create under the Indenture a new series of
Securities;

WHEREAS, additional Securities of other series hereafter established, except as

issued from time to time pursuant to the Indenture as at the time supplemented
and modified; and

WHEREAS, all conditions necessary to authorize the execution and delivery of
this Second Supplemental Indenture and to make it a valid and binding obligation

                                   ARTICLE 1

                             ESTABLISHMENT OF SERIES

Securities to be issued under the Indenture, to be designated as the Company's

                                   ARTICLE 2

                             6 7/8% NOTES DUE 2011

Section 201. Establishment. There are to be authenticated and delivered
$250,000,000 principal amount of 2011 Notes, and no further 2011 Notes shall be
authenticated and delivered except as provided by Section 304, 305, 306, 906 or
1106 of the Original Indenture. The 2011 Notes shall be issued in fully
registered form without coupons. The 2011 Notes shall be substantially in the
form set out in Exhibit A hereto.

Each 2011 Note shall be dated the date of authentication thereof and shall bear
interest from the date of original issuance thereof or from the most recent
Interest Payment Date to which interest has been paid or duly provided for.

Section 202. Definitions. The following defined terms used herein with respect
to the 2011 Notes shall, unless the context otherwise requires, have the
meanings specified below. Capitalized terms used herein for which no definition
is provided herein shall have the meanings set forth in the Original Indenture.

"Interest Payment Dates" means February 1 and August 1, commencing August 1,
2001.

"Original Issue Date" means February 2, 2001.

"Regular Record Date" means, with respect to each Interest Payment Date, the
close of business on the 15th calendar day prior to such Interest Payment Date.

"Stated Maturity" means February 1, 2011.

Section 203. Payment of Principal and Interest. The principal of the 2011 Notes
shall be due at Stated Maturity, unless earlier redeemed. The unpaid amount of
the 2011 Notes shall bear interest at the rate of 6. % per annum until paid or
duly provided for, such interest to accrue from the Original Issue Date or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for. Interest shall be paid semi-annually in arrears on each Interest
Payment Date to the Person or Persons in whose name the 2011 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 shall be paid to the Person to whom principal is
payable. Any such interest that is not so punctually paid or duly provided for
shall 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 2011 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 2011 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 2011 Notes may be listed, and upon such notice as may be
required by any such exchange, all as more fully provided in the Original
Indenture.


                                        2
<PAGE>   5

Payments of interest on the 2011 Notes shall include interest accrued to but
excluding the respective Interest Payment Dates. Interest payments for the 2011
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 on the 2011
Notes is not a Business Day, then payment of the interest payable on such date
shall be made on the next succeeding day that is a Business day (and without any
interest or payment in respect of any such delay) 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 banking
institutions in the Place of Payment are authorized or obligated by law or
executive order to remain closed or (iii) a day on which the Corporate Trust
Office is closed for business.

Payment of principal of, premium, if any, and interest on the 2011 Notes shall
be made 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. Payments of
principal of, premium, if any, and interest on the 2011 Notes represented by a
Global Security shall be made by wire transfer of immediately available funds to
the Holder of such Global Security; provided that, in the case of payments of
principal and premium, if any, such Global Security is first surrendered to a
Paying Agent. If any of the 2011 Notes are no longer represented by a Global
Security, (i) payments of principal, premium, if any, and interest due at the
Stated Maturity or earlier redemption of such 2011 Notes shall be made at the
office of any Paying Agent upon surrender of such 2011 Notes to such Paying
Agent and (ii) payments of interest shall be made, at the option of the Company,
subject to such surrender where applicable, (A) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Security
Register or (B) 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.

Section 204. Denominations. The 2011 Notes shall be issued in denominations of
$1,000 or any integral multiple thereof.

Section 205. Global Securities. The 2011 Notes shall initially be issued in the
form of one or more Global Securities registered in the name of the Depositary
(which initially shall be The Depository Trust Company) or its nominee. Except
under the limited circumstances described below, the 2011 Notes represented by
such Global Security or Global Securities shall not be exchangeable for, and
shall not otherwise be issuable as, 2011 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.

A Global Security shall be exchangeable for 2011 Notes registered in the names
of Persons other than the Depositary or its nominee only if (i) the Depositary
notifies the Company 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 Company within 90 days of receipt by the Company of such notification, or
if at any time the Depositary



                                       3
<PAGE>   6

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 Company within 90 days
after it becomes aware of such cessation, or (ii) the Company in its sole
discretion determines that such Global Security shall be so exchangeable. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for 2011 Notes registered in such names as the Depositary shall
direct.

Section 206. Redemption at the Option of the Company. The 2011 Notes shall be
redeemable, in whole or in part at any time, at the option of the Company on any
date (a "Redemption Date"), at a Redemption Price equal to the greater of (i)
100% of the principal amount of the 2011 Notes to be redeemed and (ii) the sum
of the present values of the principal amount of the 2011 Notes to be redeemed
and the remaining scheduled payments of interest thereon (exclusive of interest
accrued to the Redemption Date) from the Redemption Date to the respective
scheduled payment dates discounted from their respective scheduled payment dates
to the Redemption Date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate (as hereinafter defined) plus 20
basis points, plus, in either case, accrued and unpaid interest on the principal
amount being redeemed to such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected
by the Quotation Agent as having a maturity comparable to the term between the
Redemption Date and the Stated Maturity (the "Remaining Life") that would be
utilized, at the time of selection, and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity with the Remaining Life.

"Comparable Treasury Price" means, with respect to any Redemption Date, the
average of two Reference Treasury Dealer Quotations for such Redemption Date.

"Quotation Agent" means the Reference Treasury Dealer appointed by the Company.

"Reference Treasury Dealer" means each of Merrill Lynch Government Securities
Inc. and Chase Securities Inc., and their respective successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in The City of New York (a "Primary Treasury
Dealer"), the Company shall substitute therefor another Primary Treasury Dealer.

"Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., The City
of New York time, on the third Business Day preceding such Redemption Date.

"Treasury Rate" means, with respect to any Redemption Date, (1) the yield, under
the heading which represents the average for the immediately preceding week,
appearing in the most recently published statistical release designated "H.15
(519)" or any successor



                                       4
<PAGE>   7

publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption "Treasury
Constant Maturities," for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the Stated
Maturity, yields for the two published maturities most closely corresponding to
the Comparable Treasury Issue shall be determined, and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (2) if such release (or any successor release)
is not published during the week preceding the calculation date or does not
contain such yields, the rate per year equal to the semiannual equivalent yield
to maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for the Redemption Date. The Treasury
Rate will be calculated on the third Business Day preceding the Redemption Date.

Notwithstanding Section 1104 of the Original Indenture, the notice of redemption
with respect to the foregoing redemption need not set forth the Redemption Price
but only the manner of calculation thereof.

The Company shall notify the Trustee of the Redemption Price with respect to the
foregoing redemption promptly after the calculation thereof. The Trustee shall
not be responsible for calculating said Redemption Price.

If less than all of the 2011 Notes are to be redeemed, the Trustee shall select
the 2011 Notes or portions of 2011 Notes to be redeemed by such method as the
Trustee shall deem fair and appropriate. The Trustee may select for redemption
2011 Notes and portions of 2011 Notes in amounts of whole multiples of $1,000.

The 2011 Notes shall not have a sinking fund.

Section 207. Paying Agents. The Trustee shall initially serve as the principal
Paying Agent with respect to the 2011 Notes, and the principal Place of Payment
shall initially be the office of The Chase Manhattan Bank at 55 Water Street,
New York, New York 10041.

                                   ARTICLE 3

Indenture are made by the Company only and not by the Trustee, and all of the

respect of the 2011 Notes and this Second Supplemental Indenture as fully and
with like effect as if set forth herein in full.

Section 302. Ratification and Incorporation of Original Indenture. As
supplemented hereby, the Original Indenture is in all respects ratified and
confirmed, and the Original

Duke Energy Field Services, LLC, a limited liability company duly organized and

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 the Holder of this Security 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 the 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

Security is first surrendered to the Paying Agent. If any of the Securities of
this series are no longer represented by a Global Security, (i) payments of
principal, premium, if any, and interest due at the Stated Maturity or earlier
redemption of such Securities shall be made at the office of the Paying Agent,
which is initially at 55 Water Street, New York, New York 10041, upon surrender
of such Securities to the Paying Agent, and (ii) payments of interest shall be
made, at the option of the Company, subject to such surrender where applicable,
(A) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (B) 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.

thereunder of the Company, 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 as
the 6 7/8% Notes due 2011 (the "2011 Notes"), limited in aggregate principal
amount of $250,000,000. Capitalized terms used herein for which no definitions
are provided herein shall have the meanings set forth in the Indenture.

The 2011 Notes shall be redeemable, in whole or in part at any time, at the
option of the Company on any date (a "Redemption Date"), at a Redemption Price
equal to the greater of (i) 100% of the principal amount of the 2011 Notes to be
redeemed and (ii) the sum of the present values of the principal amount of the
2011 Notes to be redeemed and the remaining scheduled payments of interest
thereon (exclusive of interest accrued to the Redemption Date) from the
Redemption Date to the respective scheduled payment dates discounted from their
respective scheduled payment dates to the Redemption Date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate (as hereinafter defined) plus 20 basis points, plus, in either case,
accrued and unpaid interest on the principal amount being redeemed to such
Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected
by the Quotation Agent as having a maturity comparable to the term between the
Redemption Date and the Stated Maturity (the "Remaining Life") that would be
utilized, at the time of selection, and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity with the Remaining Life.

"Comparable Treasury Price" means, with respect to any Redemption Date, the
average of two Reference Treasury Dealer Quotations for such Redemption Date.

"Quotation Agent" means the Reference Treasury Dealer appointed by the Company.

"Reference Treasury Dealer" means each of Merrill Lynch Government Securities
Inc. and Chase Securities Inc., and their respective successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in The City of New York (a "Primary Treasury
Dealer"), the Company shall substitute therefor another Primary Treasury Dealer.

"Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference



                                      A-5
<PAGE>   15

Treasury Dealer at 5:00 p.m., The City of New York time, on the third Business
Day preceding such Redemption Date.

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

The Trustee shall initially serve as the principal Paying Agent with respect to
the Securities of this series, and the principal Place of Payment shall
initially be at the office of The Chase Manhattan Bank at 55 Water Street, New
York, New York 10041.

Notice of any redemption by the Company will be mailed at least 30 days but not
more than 60 days before any Redemption Date to each Holder of the 2011 Notes to
be redeemed. If less than all the 2011 Notes are to be redeemed at the option of
the Company, the Trustee shall select, in such manner as it shall deem fair and
appropriate, the 2011 Notes to be redeemed in whole or in part. The Trustee may
select for redemption the 2011 Notes and portions of the 2011 Notes in amounts
of whole multiples of $1,000.

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
Company and the rights of the Holders of the Securities of all series affected
under the Indenture at any time by the Company 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



                                      A-6
<PAGE>   16

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 Company 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.

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 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
premium or interest hereon on or after the respective due dates expressed
herein.

No reference herein to the Indenture and no provision of this Security or of the
Indenture shall alter or impair the obligation of the Company, 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.

The Indenture contains provisions for defeasance at any time of the entire
indebtedness of the Securities of this series or of any Securities of this
series and for covenant defeasance at any time of certain covenants in the
Indenture upon compliance with certain conditions set forth in the Indenture.

Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company 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 Company, 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 $1,000 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 like tenor 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
Company.
