                                 Redemption" for a description of how the
                                 redemption price is calculated. The notes do
                                 not have the benefit of a sinking fund.

Ranking.......................   The notes will be our direct and unsecured
                                 obligations and will rank equal in priority

                                 from time to time outstanding.

Certain Covenants.............   The indenture governing the notes contains
                                 certain covenants that, among other things,
                                 limit our ability and the ability of certain of
                                 our subsidiaries:

                                 - to create liens on our assets; and

                                 - to enter into sale and leaseback
                                   transactions.

                                 See "Description of Debt Securities" in the

                                USE OF PROCEEDS

     We expect our net proceeds from the offering of the notes to be
approximately $298.4 million. We intend to use the net proceeds to repay a
portion of our outstanding commercial paper. The proceeds of the commercial
paper were originally used to make one-time cash distributions of approximately
$1,525 million to Duke Energy Corporation and approximately $1,220 million to
Phillips Petroleum Company in connection with the March 31, 2000 Combination (as
described in the accompanying prospectus) and for working capital requirements.
At October 31, 2001, we had outstanding approximately $457.5 million of
commercial paper with maturity dates ranging from one day to seven days and with
annual interest rates ranging from 2.85% to 3.02%.

(1) EBITDA consists of income from continuing operations before interest
    expense, income tax expense, and depreciation and amortization expense.
    Earnings before interest and tax (EBIT) consists of income from

                                       S-4


    continuing operations before interest expense and income tax expense.
    Neither EBITDA nor EBIT is a measurement presented in accordance with
    accounting principles generally accepted in the United States. You should
    not consider either measure in isolation from or as a substitute for net
    income or cash flow measures prepared in accordance with accounting
    principles generally accepted in the United States or as a measure of our
    profitability or liquidity. EBITDA is included as a supplemental disclosure
    because it may provide useful information regarding our ability to service
    debt and to fund capital expenditures. However, not all EBITDA may be
    available to service debt.

(2) Based on the NYMEX Henry Hub prices for the periods indicated.

(3) Based on the index prices from the Mont Belvieu and Conway market hubs that
    are weighted by our component and location mix for the periods indicated.

(4) The ratio of EBITDA to interest expense represents a ratio that provides an
    investor with information as to our current ability to meet our financing
    costs.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our consolidated ratio of earnings to fixed
charges for the periods indicated. From a financial reporting perspective, we
are the successor to Duke Energy Corporation's North American midstream natural
gas business. The subsidiaries of Duke Energy Corporation that conducted this
business were contributed to us in March 2000 immediately prior to the
combination of these subsidiaries with the North American midstream natural gas
business of Phillips Petroleum Company. For periods prior to the Combination,
Duke Energy Field Services, LLC and these former subsidiaries of Duke Energy
Corporation collectively are referred to as the "Predecessor Company."

</Table>

     For purposes of calculating the ratios of earnings to fixed charges: (1)
"earnings" means income before extraordinary charges plus income taxes and fixed
charges, and (2) "fixed charges" include interest on indebtedness, amortization
of deferred financing costs, and that portion of lease expense that is deemed to
be representative of an interest factor. The ratio includes amounts from our
company, all of our majority-owned subsidiaries and our proportionate share of
distributed amounts from 50% owned investments accounted for using the equity
method.

                            DESCRIPTION OF THE NOTES

     The following description of the material terms of the 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 Debt
Securities provided under the caption "Description of Debt Securities" in the
accompanying prospectus.

GENERAL

     The notes will be limited in principal amount to $300,000,000 and will be
issued as a series of Debt Securities under the indenture dated as of August 16,
2000, as amended and supplemented, between us and The Chase Manhattan Bank, as
Trustee.

     The entire principal amount of the notes will mature and become due and
payable, together with any accrued and unpaid interest, on November 15, 2006.

     The notes will not be subject to any sinking fund provision.

                                       S-5


INTEREST

     The notes will bear interest from November 9, 2001 at the annual rate
stated on the cover page of this prospectus supplement. We will pay interest
semiannually on May 15 and November 15 of each year, commencing May 15, 2002, to
each person in whose name the notes are registered at the close of business on
the fifteenth calendar day before the relevant interest payment date. The amount
of interest payable will be computed on the basis of a 360-day year of twelve
30-day months. In the event that any date on which interest is payable is not a
business day, we will pay that interest on the next business day without any
interest or other payment due to the delay.

OPTIONAL REDEMPTION

     We will have the right to redeem the notes, in whole or in part at any
time, at a redemption price equal to the greater of (1) 100% of the principal
amount of the notes to be redeemed and (2) the sum of the present values of the
remaining scheduled payments of principal and interest on such notes (exclusive
of interest accrued to the redemption date) discounted to the redemption date on
a semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Rate plus 30 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 remaining
term of the notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of such notes.

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

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

     "Reference Treasury Dealer" means each of Banc of America Securities LLC
and Merrill Lynch Government 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 New York City (a "Primary Treasury Dealer"), we
will substitute therefor another Primary Treasury Dealer.

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

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

                                       S-6


REDEMPTION PROCEDURES

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

RANKING

     The notes will be our direct and unsecured obligations. The notes will rank
equal in priority with all of our other existing and future unsecured and
unsubordinated indebtedness and senior in right of payment to all of our
existing and future subordinated debt. At October 31, 2001, we had outstanding
approximately $2.4 billion of unsecured and unsubordinated indebtedness. The
indenture contains no restrictions on the amount of additional indebtedness that
we may issue under it.

DENOMINATIONS

     The notes will be issuable in denominations of $1,000 and integral
multiples of $1,000.

DEFEASANCE AND COVENANT DEFEASANCE

     The notes will be subject to Defeasance and Covenant Defeasance as defined
and described in the indenture. See "Description of Debt
Securities -- Defeasance and Covenant Defeasance" in the accompanying
prospectus.

BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY

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

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

     Purchases of notes within the DTC system must be made by or through direct
participants, which will receive a credit for the notes on DTC's records. The
ownership interest of each actual purchaser of notes ("beneficial owner") is in
turn to be recorded on the direct and indirect participants' records. Beneficial
owners will not receive written confirmation from DTC of their purchases, but
beneficial owners are expected to receive written confirmations providing
details of the transactions, as well as periodic statements of their holdings,
from the direct or indirect participants through which the beneficial owners
entered into the transaction. Transfers of ownership interests in the notes are
to be accomplished by entries made on the books

                                       S-7


of participants acting on behalf of beneficial owners. Beneficial owners will
not receive certificates representing their ownership interests in the notes,
except in the event that use of the book-entry system for the notes is
discontinued.

     To facilitate subsequent transfers, all notes deposited by participants
with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The
deposit of notes with DTC and their registration in the name of Cede & Co.
effect no change in beneficial ownership. DTC has no knowledge of the actual
beneficial owners of the notes. DTC's records reflect only the identity of the
direct participants to whose accounts such notes are credited, which may or may
not be the beneficial owners. The participants will remain responsible for
keeping account of their holdings on behalf of their customers.

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

     Redemption notices will be sent to DTC. If less than all of the notes are
being redeemed, DTC will reduce the amount of interest of each direct
participant in the notes in accordance with its procedures.

     Neither DTC nor Cede & Co. will consent or vote with respect to notes.
Under its usual procedures, DTC would mail an Omnibus Proxy to us as soon as
possible after the record date. The Omnibus Proxy assigns Cede & Co.'s
consenting or voting rights to those direct participants to whose account notes
are credited on the record date (identified in a listing attached to the Omnibus
Proxy).

     Payments on the notes will be made to Cede & Co., as nominee of DTC. DTC's
practice is to credit direct participants' accounts, upon DTC's receipt of funds
and corresponding detailed information, on the relevant payment date in
accordance with their respective holdings shown on DTC's records. Payments by
participants to beneficial owners will be governed by standing instructions and
customary practices, as is the case with securities held for the account of
customers in bearer form or registered in "street name," and will be the
responsibility of such participants and not of DTC or us, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payment to Cede & Co. is the responsibility of our company or of the paying
agent, disbursement of such payments to direct participants is the
responsibility of Cede & Co. and disbursement of such payments to the beneficial
owners is the responsibility of direct and indirect participants.

     Except as provided herein, a beneficial owner of an interest in a global
note will not be entitled to receive physical delivery of notes. Accordingly,
each beneficial owner must rely on the procedures of DTC to exercise any rights
under the notes. The laws of some jurisdictions require that certain purchasers
of securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in a global note.

     DTC may discontinue providing its services as securities depositary with
respect to the notes at any time by giving reasonable notice to us. Under such
circumstances, in the event that a successor securities depositary is not
obtained within 90 days, certificates representing the notes will be printed and
delivered to the holders of record. Additionally, we may decide to discontinue
use of the system of book-entry transfers through DTC (or a successor securities
depositary) with respect to the notes. In that event, certificates for such
notes will be printed and delivered to the holders of record.

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

</Table>

     The obligation of the underwriters to purchase the notes is subject to the
terms and conditions set forth in the underwriting agreement. The underwriting
agreement requires the underwriters to purchase all the notes offered by this
prospectus supplement, if any of such notes are purchased.

     Notes sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus
supplement. Any notes sold by the underwriters to securities dealers may be sold
at a discount from the initial public offering price of up to 0.35% of the
principal amount of the notes. Any such securities dealers may resell any notes
purchased from the underwriters to certain other brokers or dealers at a
discount from the initial public offering price of up to 0.25% of the principal
amount of the notes. If all of the notes are not sold at the initial public
offering price, the underwriters may change the offering price and the other
selling terms.

     The notes are a new issue of securities with no established trading market.
We have been advised by the underwriters that they intend to make a market in
the notes but are not obligated to do so and may discontinue market making at
any time without notice. We cannot assure you as to the liquidity of the trading
market for the notes.

     In connection with the offering, the underwriters may purchase and sell the
notes in the open market. These transactions may include short sales,
stabilizing transactions and purchases to cover positions created by short
sales. Short sales involve the sale by the underwriters of a greater aggregate
principal amount of notes than they are required to purchase in the offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the notes
while the offering is in progress.

     The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because they have repurchased notes sold by or for the
account of such underwriter in stabilizing or short covering transactions.

     The expenses of the offering, not including the underwriting discount, are
estimated to be approximately $200,000. The underwriters have agreed to
reimburse us $750,000, of which approximately $200,000 is for expenses of the
offering.

     We have agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, and to
contribute to payments in respect thereto.

     In the ordinary course of their respective businesses, the underwriters and
their affiliates have engaged, and may in the future engage, in commercial
banking and/or investment banking transactions with us and our affiliates.
Because more than ten percent of the net proceeds of this offering may be paid
to members or affiliates of members of the National Association of Securities
Dealers, Inc. participating in the offering, the offering will be conducted in
accordance with NASD Conduct Rule 2710(c)(8).

                             ABOUT THIS PROSPECTUS

     This prospectus is part of registration statements that we filed with the
Securities and Exchange Commission using the "shelf" registration process. Under
this shelf registration process, we may issue the debt securities described in
this prospectus in one or more offerings up to a total dollar amount of
$550,000,000 (or its equivalent in foreign currencies).

     This prospectus constitutes part of the registration statements on Form S-3

the registration statements for further information with respect to us and the
securities we are offering. Any statement contained in this prospectus
concerning the provisions of any document filed as an exhibit to the
registration statements or otherwise filed with the SEC is not necessarily
complete, and in each instance reference is made to the copy of the document
filed.

     This prospectus provides you with a general description of the debt
securities that we may offer. Each time we sell debt securities, we will provide
a prospectus supplement that will contain specific information about the terms
of that offering and the debt securities to be sold. The prospectus supplement
may also add, update or change information contained in this prospectus. Any
statement that we make in this prospectus will be modified or superseded by any
inconsistent statement made by us in a prospectus supplement. The registration
statements filed with the SEC includes exhibits that provide more details about
the matters discussed in this prospectus. You should read this prospectus, the
related exhibits filed with the SEC and any prospectus supplement, together with
the additional information described under "Where You Can Find More
Information."

                      WHERE YOU CAN FIND MORE INFORMATION

an important part of this prospectus, and information that we file later with
the SEC will automatically update and supersede this information. We incorporate
by reference the documents listed below and any future filings made with the SEC

             CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS

     This prospectus contains or incorporates by reference statements that do
not directly or exclusively relate to historical facts. Such statements are
"forward-looking statements." You can typically identify forward-looking
statements by the use of forward-looking words, such as "may," "could,"
"project," "believe," "anticipate," "expect," "estimate," "potential," "plan,"
"forecast" and other similar words.

     All statements other than statements of historical facts contained in this
prospectus, including statements regarding our future financial position,
business strategy, budgets, projected costs and plans and objectives of
management for future operations, are forward-looking statements.

     The forward-looking statements in this prospectus reflect our intentions,
plans, expectations, assumptions and beliefs about future events and are subject
to risks, uncertainties and other factors, many of which are outside our
control. Important factors that could cause actual results to differ materially
from the expectations expressed or implied in the forward-looking statements
include known and unknown risks. Known risks include, but are not limited to the
following:

     - the timing and extent of changes in commodity prices and demand for our
       services;

     - our use of derivative financial instruments to hedge commodity and
       interest rate risks;

     - our ability to access the debt and equity markets, which will depend on
       general market conditions and the credit ratings for our debt
       obligations;

     - changes in laws and regulations, particularly with regard to taxes,
       safety and protection of the environment or the increased regulation of
       the gas gathering and processing industry;

     - weather and other natural phenomena;

     - industry changes, including the impact of consolidations, and changes in
       competition;

     - our ability to obtain required approvals for construction or
       modernization of gathering and processing facilities, and the timing of
       production from such facilities, which are dependent on the issuance by
       federal, state and municipal governments or agencies of building,
       environmental and other permits, the availability of specialized
       contractors and work force and prices of and demand for products; and

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

     In light of these risks, uncertainties and assumptions, the forward-looking
events referred to in this prospectus or in any prospectus supplement might not
occur or might occur to a different extent or at a different time than described
in this prospectus or in any prospectus supplement. Except as otherwise required
by law, we undertake no obligation to update or revise our forward-looking
statements, whether as a result of new information, future events or otherwise.

                                        2


                                  OUR COMPANY

     Duke Energy Field Services, LLC is a company that holds the combined North
American midstream natural gas gathering, processing, marketing and natural gas
liquids businesses of Duke Energy Corporation ("Duke Energy") and Phillips
Petroleum Company ("Phillips"). The transaction in which those businesses were
combined on March 31, 2000 is referred to in this prospectus as the
"Combination." Our limited liability company agreement limits the scope of our
business to the midstream natural gas industry in the United States and Canada,
the marketing of natural gas liquids in Mexico and the transportation, marketing
and storage of other petroleum products, unless otherwise approved by our Board
of Directors.

     Unless the context otherwise requires, descriptions of assets, operations
and results in this prospectus give effect to the Combination and related
transactions, the transfer to us of additional midstream natural gas assets
acquired by Duke Energy or Phillips prior to the Combination and the transfer to
us of the general partner of TEPPCO Partners, L.P. ("TEPPCO"). In this
prospectus, the terms "we," "us" and "our" refer to Duke Energy Field Services,
LLC and our subsidiaries, giving effect to the Combination and related
transactions.

     The midstream natural gas industry is the link between the exploration and
production of raw natural gas and the delivery of its components to end-use
markets. We operate in the two principal business segments of the midstream
natural gas industry:

     - natural gas gathering, processing, transportation and storage; and

     - natural gas liquids ("NGLs") fractionation, transportation, marketing and
       trading.

     We believe that we are one of the largest gatherers of raw natural gas,
based on wellhead volume, in North America. We are the largest producer, and we
believe that we are one of the largest marketers, of NGLs in North America. In
2000:

     - we gathered and/or transported an average of approximately 7.6 trillion
       British thermal units per day of raw natural gas;

     - we produced an average of approximately 360,000 barrels per day of NGLs;
       and

     - we marketed and traded an average of approximately 500,000 barrels per
       day of NGLs.

     We gather raw natural gas through gathering systems located in seven major
natural gas producing regions: Permian Basin, Mid-Continent, East
Texas -- Austin Chalk -- North Louisiana, Onshore Gulf of Mexico, Rocky
Mountains, Offshore Gulf of Mexico and Western Canada. Our gathering systems
consist of approximately 57,000 miles of gathering pipe, with approximately
35,000 active connections to producing wells.

     Our natural gas processing operations involve the separation of raw natural
gas gathered both by our gathering system and by third party systems into NGLs
and residue gas. We process the raw natural gas at our 68 owned and operated
plants and at 11 third-party operated facilities in which we hold an equity
interest.

     The NGLs separated from the raw natural gas by our processing operations
are either sold and transported as "NGL raw mix" or further separated through a
process known as fractionation into their individual components (ethane,
propane, butanes and natural gasoline) and then sold as components. We
fractionate NGL raw mix at our 12 owned and operated processing facilities and
at two third-party operated fractionators in which we hold an equity interest.

     We sell NGLs to a variety of customers ranging from large, multi-national
petrochemical and refining companies to small regional retail propane
distributors. Substantially all of our NGL sales are made at market-based
prices, including the approximately 40% of our NGL production that is committed
to Phillips under an existing 15-year contract, of which 14 years remain.

                                        3


     The residue gas that results from our processing is sold at market-based
prices to marketers or end users including large industrial customers and
natural gas and electric utilities serving individual consumers. We market
residue gas through our wholly owned gas marketing company. We also store
residue gas at our 8.5 billion cubic foot natural gas storage facility.

     On March 31, 2000, we obtained by transfer from Duke Energy the general
partner of TEPPCO Partners, L.P., a publicly traded limited partnership which
owns and operates a network of pipelines for refined products and crude oil. The
general partner is responsible for the management and operations of TEPPCO. We
believe that our ownership of the general partner of TEPPCO improves our
business position in the transportation sector of the midstream natural gas
industry and provides additional flexibility in pursuing our disciplined
acquisition strategy by providing an alternative acquisition vehicle. It also
provides us with an opportunity to sell appropriate assets currently held by our
company to TEPPCO. Through our ownership of the general partner of TEPPCO we
have the right to receive from TEPPCO incentive cash distributions in addition
to a 2% share of distributions based on our general partner interest. At
TEPPCO's 2000 per unit distribution level, the general partner:

     - receives approximately 20% of the cash distributed by TEPPCO to its
       partners, which consists of 18% from the incentive cash distribution and
       2% from the general partner interest; and

     - under the incentive cash distribution provisions, receives 50% of any
       increase in TEPPCO's per unit cash distributions.

     Our principal executive offices are located at 370 17th Street, Suite 900,
Denver, Colorado 80202, and our telephone number is (303) 595-3331.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table contains our consolidated ratio of earnings to fixed
charges for the periods indicated. From a financial reporting perspective, we
are the successor to Duke Energy's North American midstream natural gas
business. The subsidiaries of Duke Energy that conducted this business were
contributed to us in March 2000 immediately prior to the combination of these
subsidiaries with the North American midstream natural gas business of Phillips
Petroleum Company. For periods prior to the Combination, Duke Energy Field
Services, LLC and these former subsidiaries of Duke Energy collectively are
referred to as the "Predecessor Company."

     Unless the applicable prospectus supplement states otherwise, we will use
the net proceeds from the sale of the debt securities offered by this prospectus
and any prospectus supplement for general corporate purposes, which may include
repayment of indebtedness, capital expenditures, future acquisitions, advances
to subsidiaries and additions to our working capital. If we do not use the net
proceeds immediately, we may temporarily invest them in short-term
interest-bearing obligations or deposit them with banks.

                         DESCRIPTION OF DEBT SECURITIES

     Any debt securities issued using this prospectus ("Debt Securities") will
be our direct unsecured general obligations. The Debt Securities will be senior
debt securities.

     The Debt Securities will be issued under an Indenture (the "Indenture")
between us and The Chase Manhattan Bank (the "Trustee").

     The Debt Securities may be issued from time to time in one or more series.
The particular terms of each series that is offered by a prospectus supplement
will be described in the prospectus supplement.

     We have summarized selected provisions of the Indenture below. The summary
is not complete. The form of the Indenture has been filed as an exhibit to the
registration statement, and you should read the Indenture for provisions that
may be important to you. Whenever we refer in this prospectus or in any
prospectus supplement to particular sections or defined terms of the Indenture,
such sections or defined terms are incorporated by reference herein or therein,
as applicable. Capitalized terms used in this summary have the meanings
specified in the Indenture.

GENERAL

     The Indenture provides that Debt Securities in separate series may be
issued from time to time without limitation as to aggregate principal amount. We
may specify a maximum aggregate principal amount for the Debt Securities of any
series. We will determine the terms and conditions of the Debt Securities,
including the maturity, principal and interest, but those terms must be
consistent with the Indenture. Debt Securities of a series need not be issued at
the same time, bear interest at the same rate or mature on the same date.

     Each series of Debt Securities will rank equally with every other series of
Debt Securities and with all of our other unsecured and unsubordinated debt.

     A prospectus supplement relating to any series of Debt Securities being
offered will include specific terms related to the offering, including the price
or prices at which the Debt Securities to be offered will be issued. These terms
will include some or all of the following:

     - the title of the Debt Securities;

     - the total principal amount of the Debt Securities;

     - the date or dates on which the principal of the Debt Securities will be
       payable or the method for determining the date or dates, and any right
       that we have to change the date on which principal is payable;

     - the interest rate or rates of the Debt Securities, 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 we may extend the interest payment periods and, if so, the terms
       of the extension;

     - the places where payments on the Debt Securities will be payable;

     - whether we have the option to redeem the Debt Securities and, if so, the
       terms of our redemption option;

     - any obligation we have to redeem the Debt Securities through a sinking
       fund or to purchase the Debt Securities through a purchase fund or at the
       option of the holder;

     - whether the Debt Securities are defeasible;

     - 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;
                                        6


     - if payments may be made, at our election or at the holder's election, in
       a currency other than that in which the Debt Securities 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 Debt Securities will be issuable as global securities and, if
       so, the securities depositary;

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

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

     - any addition to or change in the events of default in the Indenture;

     - any addition to or change in the covenants in the Indenture; and

     - any other terms of the Debt Securities not inconsistent with the
       provisions of the Indenture.

     Unless we state otherwise in the prospectus supplement, we will issue the
Debt Securities only in fully registered form, without coupons, and there will
be no service charge for any registration of transfer or exchange of the Debt
Securities. We may, however, require payment to cover any tax or other
governmental charge payable in connection with any transfer or exchange. Subject
to the terms of the Indenture and the limitations applicable to global
securities, Debt Securities may be transferred or exchanged at the corporate
trust office of the Trustee or at any other office or agency maintained by us
for such purpose.

     The Debt Securities of each series will be issuable in denominations of
$1,000 and any integral multiples of $1,000, unless we state otherwise in the
prospectus supplement.

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

RANKING

     Each series of Debt Securities will be unsecured senior obligations and
will rank equally with every other series of Debt Securities and with all of our
other unsecured and unsubordinated debt. The Debt Securities will, however, be
effectively subordinated in right of payment to any secured indebtedness to the
extent of the value of the assets securing that indebtedness. Except as provided
in the Indenture or specified in any authorizing resolution or supplemental
indenture relating to a series of Debt Securities to be issued, the Indenture
will not limit the amount of additional indebtedness that may rank equally with
the Debt Securities or the amount of indebtedness, secured or otherwise, that
may be incurred or preferred stock that may be issued by any of our
subsidiaries.

GLOBAL SECURITIES

     We may issue some or all of the Debt Securities as book-entry securities.
Any such book-entry securities will be represented by one or more fully
registered global certificates. We 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.

                                        7


     As long as the securities depositary or its nominee is the registered
holder of a global security representing Debt Securities, that person will be
considered the sole owner and holder of the global security and the Debt
Securities 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 Debt Securities it represents
       registered in their names;

     - may not receive or be entitled to receive physical delivery of
       certificated Debt Securities in exchange for the global security; and

     - will not be considered the owners or holders of the global security or
       any Debt Securities it represents for any purposes under the Debt
       Securities or the Indenture.

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

     Ownership of beneficial interests in a global security will be limited to
institutions having accounts with the securities depositary or its nominee,
which are called "participants" in this discussion, and to persons that hold
beneficial interests through participants. When a global security representing
Debt Securities is issued, the securities depositary will credit on its
book-entry, registration and transfer system the principal amounts of Debt
Securities 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 Debt Securities, for payments made on account of those beneficial
interests or for maintaining, supervising or reviewing any records relating to
those beneficial interests:

     - our company;

     - the Trustee under the Indenture; or

     - an agent of either our company or the Trustee.

REDEMPTION

     Any provisions relating to the redemption of Debt Securities will be set
forth in the applicable prospectus supplement. Unless we state otherwise in the
applicable prospectus supplement, we may redeem Debt Securities only upon notice
mailed at least 30 but not more than 60 days before the date fixed for
redemption. Unless we state otherwise in the applicable prospectus supplement,
that notice may state that the redemption will be conditional upon the Trustee
or the paying agent receiving sufficient funds to pay the principal, premium and
interest on those Debt Securities on the date fixed for redemption and that if
the Trustee or the paying agent does not receive those funds, the redemption
notice will not apply, and we will not be required to redeem those Debt
Securities.

                                        8


     We will not be required to:

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

     - register the transfer of, or exchange any Debt Security of that series
       selected for redemption except the unredeemed portion of a Debt Security
       being partially redeemed.

CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER

     The Indenture provides that we may consolidate or merge with or into, or
convey or transfer all or substantially all of our properties and assets to,
another corporation or other entity. Any successor must, however, assume our
obligations under the Indenture and the Debt Securities, and we must deliver an
officers' certificate and an opinion of counsel to the Trustee that affirms
compliance with all conditions in the Indenture. When those conditions are
satisfied, the successor will succeed to and be substituted for us under the
Indenture, and we will be relieved of our obligations under the Indenture and
the Debt Securities.

EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, each of
the following will constitute an event of default under the Indenture:

     - failure to pay principal of or premium on any Debt Security of that
       series when due;

     - failure to pay when due any interest on any Debt Security of that series
       that continues for 60 days; for this purpose, the date on which interest
       is due is the date on which we are required to make payment following any
       deferral of interest payments by us under the terms of Debt Securities
       that permit such deferrals;

     - failure to make any sinking fund payment when required for any Debt
       Security of that series that continues for 60 days;

     - failure to perform any covenant in the 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 Debt Securities of that series give us written notice of the
       default;

     - certain events of bankruptcy, insolvency or reorganization affecting us;
       and

     - any other event of default that may be provided with respect to Debt
       Securities of that series.

     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 Debt
Securities of that series, together with the Trustee, may also extend the grace
period. The grace period will be automatically extended if we have initiated and
are diligently pursuing corrective action.

     If an event of default with respect to Debt Securities of a series occurs
and is continuing, then the Trustee or the holders of at least 33% of the
outstanding Debt Securities of that series may declare the principal amount of
all Debt Securities 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:

     - we have 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

                                        9


       interest, to the extent legally permitted, in each case with respect to
       that series, and all amounts due to the Trustee; and

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

     The Trustee is under no obligation to exercise any of its rights or powers
at the request or direction of any holders of Debt Securities unless those
holders have offered the Trustee security or indemnity against the costs,
expenses and liabilities that it might incur as a result. The holders of a
majority in principal amount of the outstanding Debt Securities 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 Debt Securities. 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 Debt Security will have an absolute and unconditional
right to receive payment of the principal, any premium and, within certain
limitations, any interest on that Debt Security on its maturity date or
redemption date and to enforce those payments.

     If certain payments on a series of Debt Securities are insured by a
financial guaranty insurance policy or other policy, terms other than those that
are described in the preceding three paragraphs may apply to that series.

     We will be required to furnish to the Trustee annually a statement by
certain of our officers to the effect that we are not in default under the
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 Debt Securities only if
those Debt Securities are surrendered to it. Unless we state otherwise in the
applicable prospectus supplement, the paying agent will pay interest on Debt
Securities, subject to such surrender, where applicable, at its office or, at
our 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 Debt Securities.

     Unless we state otherwise in the applicable prospectus supplement, the
Trustee will act as paying agent for that series of Debt Securities, and the
principal corporate trust office of the Trustee will be the office through which
the paying agent acts. We may, however, change or add paying agents or approve a
change in the office through which a paying agent acts.

     Any money that we have paid to a paying agent for principal or interest on
any Debt Securities that remains unclaimed at the end of two years after that
principal or interest has become due will be repaid to us at our request. After
repayment to us, holders should look only to us for those payments.

NEGATIVE PLEDGE

     While any of the Debt Securities remain outstanding, we will not, and will
not permit any Principal Subsidiary (as defined below) to, create, or permit to
be created or to exist, any mortgage, lien, pledge, security interest or other
encumbrance upon any Principal Property (as defined below) of ours or of a
Principal Subsidiary, or upon any shares of stock of any Principal Subsidiary,
whether such Principal Property is, or shares of stock are, owned on or acquired
after the date of the Indenture, to secure any of

                                        10


our indebtedness for borrowed money, unless the Debt Securities then outstanding
are equally and ratably secured for so long as any such indebtedness is so
secured.

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

     - purchase money mortgages, or other purchase money liens, pledges,
       security interests or encumbrances upon property that we or any Principal
       Subsidiary acquired after the date of the Indenture; mortgages, liens,
       pledges, security interests or other encumbrances existing on any
       property or shares of stock at the time we or any Principal Subsidiary
       acquired it or them, including those which exist on any property or
       shares of stock of an entity with which we or any Principal Subsidiary
       are consolidated or merged or which transfers or leases all or
       substantially all of its properties to us or any Principal Subsidiary; or
       conditional sales agreements or other title retention agreements and
       leases in the nature of title retention agreements with respect to any
       property that we or any Principal Subsidiary acquired after the date of
       the Indenture; provided, however, that no such mortgage, lien, pledge,
       security interest or other encumbrance shall extend to or cover any other
       property that we or any Principal Subsidiary owns;

     - mortgages, liens, pledges, security interests or other encumbrances upon
       any of our property or the property of any Principal Subsidiary or shares
       of stock of any Principal Subsidiary that existed on the date of the
       initial issuance of Debt Securities or upon the property or shares of
       stock of any corporation existing at the time that entity became a
       Principal Subsidiary;

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

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

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

     - mortgages, liens, pledges, security interests or other encumbrances on
       any property arising in connection with any defeasance, covenant
       defeasance or in-substance defeasance of our or any Principal
       Subsidiary's indebtedness, including the Debt Securities;

     - mortgages, liens, pledges, security interests or other encumbrances in
       favor of the United States of America, any State, any foreign country or
       any department, agency or instrumentality or political subdivision of any
       such jurisdiction, to secure partial, progress, advance or other payments
       pursuant to any contract or statute or to secure any indebtedness
       incurred for the purpose of financing all or any part of the purchase
       price or the cost of constructing or improving the property subject to
       such mortgages, including, without limitation, mortgages to secure
       indebtedness of the pollution control or industrial revenue bond type;

     - indebtedness which may be issued by us or any of our Principal
       Subsidiaries in connection with our consolidation or merger or the
       consolidation or merger of any of our Principal Subsidiaries with or into
       any other entity in exchange for or otherwise in substitution for secured
       indebtedness of that entity ("Third Party Debt") which by its terms (1)
       is secured by a mortgage on all or a portion of the property of that
       entity, (2) prohibits secured indebtedness from being incurred by that
       entity, unless the Third Party Debt is secured equally and ratably with
       such secured indebtedness, or (3) prohibits secured indebtedness from
       being incurred by that entity;

     - indebtedness of any entity which we or any Principal Subsidiary are
       required to assume in connection with a consolidation or merger of that
       entity, with respect to which any of our or any Principal Subsidiary's
       property is subjected to a mortgage, lien, pledge, security interest or
       other encumbrance;

                                        11


     - mortgages, liens, pledges, security interests or other encumbrances on
       property held or used by us or any Principal Subsidiary in connection
       with the gathering, processing, transportation or marketing of natural
       gas, oil or other minerals;

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

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

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

In addition, we or any Principal Subsidiary may create or assume any other
mortgage, lien, pledge, security interest or other encumbrance not excepted in
the Indenture without us equally and ratably securing the Debt Securities, if
immediately after that creation or assumption, our principal amount of
indebtedness for borrowed money that all such other mortgages, liens, pledges,
security interests and other encumbrances secure does not exceed an amount equal
to 10% of our Consolidated Adjusted Net Assets as shown on our consolidated
balance sheet for the accounting period occurring immediately before the
creation or assumption of that mortgage, lien, pledge, security interest or
other encumbrance.

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

LIMITATION ON SALES AND LEASEBACKS

     Neither we nor any Principal Subsidiary may enter into any Sale and
Leaseback Transaction unless:

     - we or that Principal Subsidiary would be entitled to incur indebtedness
       in a principal amount equal to the Attributable Debt with respect to such
       Sale and Leaseback Transaction, secured by a mortgage, lien, pledge,
       security interest or other encumbrance on the property subject to such
       Sale and Leaseback Transaction without equally and ratably securing the
       Debt Securities pursuant to the covenant described above under "Negative
       Pledge";

     - after the date on which the Debt Securities are originally issued and
       within a period beginning 12 months prior to the consummation of such
       Sale and Leaseback Transaction and ending 12

                                        12

       months after the consummation of such Sale and Leaseback Transaction, we
       or any Subsidiary shall have expended for property used or to be used in
       our business or the business of our Subsidiaries an amount equal to all
       or a portion of the net proceeds from such Sale and Leaseback Transaction
       and we shall have elected to designate such amount as a credit against
       such Sale and Leaseback Transaction (with any amount not being so
       designated to be applied as set forth in the following bullet point);

     - during the 12-month period after the effective date of such Sale and
       Leaseback Transaction, we shall have applied to the voluntary defeasance
       or retirement of Debt Securities or any other indebtedness an amount
       equal to the greater of the net proceeds of the sale or transfer of the
       property leased in such Sale and Leaseback Transaction and the fair
       value, as determined by our Board of Directors, of such property at the
       time such Sale and Leaseback Transaction was entered into (in either case
       adjusted to reflect the remaining term of the lease and any amount we
       expend as set forth in the preceding bullet point), less an amount equal
       to the principal amount of such Debt Securities or other indebtedness
       voluntarily defeased or retired within such 12-month period and not
       designated as a credit against any other Sale and Leaseback Transaction
       that we or any of our Subsidiaries enter into during such period; or

     - such Sale and Leaseback Transaction is with one of our Affiliates.

This restriction will not apply to certain Sale and Leaseback Transactions
between us and a Principal Subsidiary or between Principal Subsidiaries.

     For purposes of the preceding paragraph, the following terms have these
meanings: "Sale and Leaseback Transaction" means an arrangement with any lender
or investor or to which such lender or investor is a party providing for the
leasing for a term of greater than three years of any property or asset which
has been or is being sold or transferred more than 18 months after its
acquisition or the completion of construction or beginning of operation thereof
to such lender or investor or to any entity to whom funds have been or are to be
advanced by such lender or investor on the security of the property or asset;
"Affiliate" of a specified person or entity means any other person or entity
directly or indirectly controlling or controlled by or under direct or indirect
common control with such specified person or entity; "Attributable Debt" means
the total net amount of rent (discounted at the rate per year indicated in the
Indenture) required to be paid during the remaining term of any lease; and
"Consolidated Adjusted Net Assets" means the total amount of assets after
deducting:

     - all current liabilities (excluding any which are by their terms
       extendible or renewable at the option of the obligor to a time more than
       12 months after the time as of which the amount is being computed); and

     - total prepaid expenses and deferred charges.

MODIFICATION AND WAIVER

     The Indenture may be modified with the consent of the holders of a majority
in principal amount of the outstanding Debt Securities of all series affected by
the modification (voting as one class). The consent of the holder of each
outstanding Debt Security affected is, however, required to:

     - change the maturity date of the principal, or any installment of
       principal or interest on that Debt Security;

     - reduce the principal amount, the interest rate or any premium payable
       upon redemption of that Debt Security;

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

     - change the currency of payment of principal, premium or interest on that
       Debt Security;

                                        13


     - 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 Debt Securities of any
       series required to amend or modify the Indenture, waive compliance with
       certain restrictive provisions of the Indenture or waive certain
       defaults; or

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

     In addition, we may supplement the Indenture to create new series of Debt
Securities and for certain other purposes, without the consent of any holders of
Debt Securities.

     The holders of a majority in principal amount of the outstanding Debt
Securities of any series may waive, for that series, our compliance with certain
restrictive provisions of the Indenture, including the covenants described under
"Negative Pledge" and "Limitation on Sales and Leasebacks". The holders of a
majority in principal amount of the outstanding Debt Securities of all series
with respect to which a default has occurred and is continuing, voting as one
class, may waive that default for all those series, except a default in the
payment of principal or any premium or interest on any Debt Security or a
default with respect to a covenant or provision that cannot be amended or
modified without the consent of the holder of each outstanding Debt Security of
the series affected.

     If certain payments on a series of Debt Securities are insured by a
financial guaranty insurance policy or other policy, terms other than those that
are described in the preceding paragraph may apply to that series.

DEFEASANCE AND COVENANT DEFEASANCE

     If, and to the extent, indicated in the applicable prospectus supplement,
we may elect, at our option at any time, to have the provisions of the Indenture
relating to defeasance or covenant defeasance applied to the Debt Securities of
any series or to any part of a series. The Indenture provides that we may be:

     - discharged from our obligations, with certain limited exceptions, with
       respect to any series of Debt Securities, as described in the Indenture,
       such a discharge being called a "defeasance" in this prospectus; and

     - released from our obligations under the covenants described in "Negative
       Pledge" and "Limitations on Sales and Leasebacks" and any restrictive
       covenants that may be especially established with respect to any series
       of Debt Securities, such a release being called a "covenant defeasance"
       in this prospectus.

We must satisfy certain conditions to effect a defeasance or covenant
defeasance. Those conditions include the irrevocable deposit with the Trustee,
in trust, of money or government obligations that through their scheduled
payments of principal and interest would provide sufficient money to pay the
principal and any premium and interest on those Debt Securities on the maturity
dates of those payments or upon redemption. Additional conditions, if any, to
exercising defeasance or covenant defeasance with respect to any series of Debt
Securities will be described in the applicable prospectus supplement.

     Following a defeasance, payment of the Debt Securities defeased may not be
accelerated because of an event of default. Following a covenant defeasance, the
payment of Debt Securities may not be accelerated by reference to the covenants
from which we have been released. A defeasance may occur after a covenant
defeasance.

     Under current U.S. federal income tax laws, a defeasance would be treated
as an exchange of the relevant Debt Securities in which holders of those Debt
Securities might recognize gain or loss. In addition, the amount, timing and
character of amounts that holders would thereafter be required to include in
income might be different from that which would be includible in the absence of
that defeasance. We

                                        14


urge investors to consult their own tax advisors as to the specific consequences
of a defeasance, including the applicability and effect of tax laws other than
U.S. federal income tax laws.

     Under current U.S. federal income tax laws, unless accompanied by other
changes in the terms of the Debt Securities, a covenant defeasance should not be
treated as a taxable exchange.

CONCERNING THE TRUSTEE

     The Trustee will perform only those duties that are specifically set forth
in the Indenture unless an event of default occurs and is continuing. In case an
event of default occurs and is continuing, the 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 Trustee is under no obligation
to exercise any of its powers under the Indenture at the request of any holder
of Debt Securities unless that holder offers reasonable indemnity to the Trustee
against the costs, expenses and liabilities that it might incur as a result.

NOTICE

     Notice to holders of Debt Securities will be given by mail to such holders
as they may appear in the security register.

TITLE

     We, the Trustee and any agent of our company or of the Trustee may treat
the person in whose name a Debt Security is registered as the absolute owner of
the Debt Security, whether or not such Debt Security may be overdue, for the
purpose of making payment and for all other purposes.

GOVERNING LAW

     The Indenture and the Debt Securities will be governed by, and construed in
accordance with, the laws of the State of New York.

                              PLAN OF DISTRIBUTION

     We may sell the Debt Securities:

     - through underwriters or dealers;

     - through agents;

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

     - through a combination of any of these methods of sale.

     The applicable prospectus supplement will describe the terms under which
the offered Debt Securities are offered, including:

     - the names of any underwriters, dealers or agents;

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

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

     - any initial public offering price; and

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

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

                                        15


     If underwriters participate in the sale of the offered Debt Securities,
those underwriters will acquire the Debt 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. If the Debt Securities are sold through underwriters, the applicable
prospectus supplement will state the names and any compensation that may be paid
to the underwriters.

     Unless we state otherwise in the applicable prospectus supplement, the
obligations of any underwriter to purchase the offered Debt Securities will be
subject to conditions, and the underwriter will be obligated to purchase all the
Debt Securities offered, except that in some cases involving a default by an
underwriter, less than all of the Debt Securities offered may be purchased.

     If the offered Debt Securities are sold through an agent, the applicable
prospectus supplement will state the name and any compensation that may be paid
to the agent. Unless we state otherwise in the applicable prospectus supplement,
that agent will be acting on a best-efforts basis for the period of its
appointment.

     We may have agreements with the underwriters, dealers and agents to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act, or to contribute with respect to payments that the
underwriters, dealers or agents may be required to make.

     Underwriters, dealers, agents and their affiliates may engage in
transactions with us or our affiliates, and may from time to time perform
services for us or our affiliates in the ordinary course of their business.

     We may authorize agents, underwriters or dealers to solicit offers by
certain institutional investors to purchase offered Debt Securities providing
for payment and delivery on a future date specified in the applicable prospectus
supplement. Institutional investors to which such offers may be made, when
authorized, include commercial and savings banks, insurance companies, pension
funds, investment companies, education and charitable institutions and such
other institutions as may be approved by us. The obligations of any such
purchasers under such delayed delivery and payment arrangements will be subject
to the condition that the purchase of the offered Debt Securities will not at
the time of delivery be prohibited under applicable law. The underwriters and
such agents will not have any responsibility with respect to the validity or
performance of such contracts.

     The Debt Securities may or may not be listed on a national securities
exchange.
