excluding historical information, include forward-looking
statements -- statements that discuss our expected future results based on
current and pending business operations. We make these forwarding-looking
statements in reliance on the safe harbor protections provided under the Private

     Forward-looking statements can be identified by words such as
"anticipates," "believes," "expects," "planned," "scheduled" or similar

reasonable assumptions, statements made regarding future results are subject to
numerous assumptions, uncertainties and risks that may cause future results to
be materially different from the results stated or implied in this document.

     The following are important factors that could cause actual results to
differ materially from any results projected, forecasted, estimated or budgeted:

     - changes in general economic conditions in the United States and changes
       in the industries in which we conduct business;

     - changes in federal or state laws and regulations to which we are subject,
       including tax, environmental and employment laws and regulations;

     - the cost and effects of legal and administrative claims and proceedings
       against us or our subsidiaries;

     - conditions of the capital markets we utilize to access capital to finance
       operations;

     - the ability to raise capital in a cost-effective way;

     - the effect of changes in accounting policies;

     - the ability to manage rapid growth;

     - the ability to control costs;

     - the ability to successfully implement key systems, such as service
       delivery systems;

     - the impact of future federal and state regulations of business
       activities, including allowed rates of return, the pace of deregulation
       in retail natural gas and electricity markets, and the resolution of
       other regulatory matters discussed herein;

     - our ability to develop expanded markets and product offerings as well as
       our ability to maintain existing markets;

     - our ability and the ability of our subsidiaries to obtain governmental
       and regulatory approval of various expansion projects;

     - future utilization of pipeline capacity, which can depend on energy
       prices, competition from other pipelines and alternative fuels, the
       general level of natural gas and petroleum product demand, decisions by
       customers not to renew expiring natural gas transportation contracts, and
       weather conditions; and

     - global and domestic economic repercussions from terrorist activities and
       the government's response thereto.

                                 tax purposes. See the discussion below under

                                 offered for resale, resold or otherwise

                                 of Exchanging or Failing to Exchange Old
                                 Notes."

                    CONSEQUENCES OF NOT EXCHANGING OLD NOTES

     If you do not exchange your old notes in the exchange offer, your old notes
will continue to be subject to the restrictions on transfer described in the
legend on the certificate for your old notes. In general, you may offer or sell
your old notes only:

     - if they are registered under the Securities Act and applicable state
       securities laws;

     - if they are offered or sold under an exemption from registration under
       the Securities Act and applicable state securities laws; or

     - if they are offered or sold in a transaction not subject to the
       Securities Act and applicable state securities laws.

     We do not currently intend to register the old notes under the Securities
Act. Under some circumstances, however, holders of the old notes, including
holders who are not permitted to participate in the exchange offer or who may
not freely resell new notes received in the exchange offer, may require us to
file, and cause to become effective, a shelf registration statement covering
resales of old notes by these holders. For more information regarding the
consequences of not tendering your old notes and our obligation to file a shelf
registration statement, see "The Exchange Offer -- Consequences of Exchanging or
Failing to Exchange Old Notes" and "Exchange Offer; Registration Rights."

                      SUMMARY DESCRIPTION OF THE NEW NOTES

     The terms of the new notes and those of the outstanding old notes are
substantially identical, except that the transfer restrictions and registration
rights relating to the old notes do not apply to the new notes. In addition, if

     - we do not file a registration statement on or prior to September 16,
       2002,

     - this registration statement is not declared effective on or prior to
       October 31, 2002 or the exchange offer is not completed within 60 days
       after the registration statement is declared effective,

     - the exchange offer is not consummated by December 30, 2002,

     - we are obligated to file a shelf registration statement and we fail to do
       so prior to the 75th day after the obligation arises or the shelf
       registration statement is not declared effective prior to the 60th day
       after the date of filing, or

     - if the shelf registration statement ceases to be effective or usable,

we agree to pay liquidated damages in an amount equal to 0.25% per annum of the
principal amount of old notes for the first 90-day period immediately following
a default, increasing to 0.50% per annum thereafter.

     We did not file this registration statement on or prior to September 16,
2002, nor was it declared effective on or prior to October 31, 2002. Therefore,
liquidated damages have been accruing since
                                        5


September 17, 2002. The liquidated damages will cease to accrue as of the date
of this prospectus. However, since the exchange offer will not be consummated by
December 30, 2002, liquidated damages will begin to accrue from December 31,
2002 until such time as the exchange offer is consummated.

                                 year, commencing on January 15, 2003.

Ranking.......................   The new notes will be our unsecured and
                                 unsubordinated obligations and will rank
                                 equally with our other existing and future
                                 unsecured and unsubordinated indebtedness.

Sinking Fund..................   None.

Optional Redemption...........   We may redeem some or all of the notes at any
                                 time at the "make-whole" price, plus accrued
                                 and unpaid interest, if any, to the redemption
                                 date. See the discussion below under the
                                 caption "Description of Notes -- Terms and
                                 Conditions of the Notes -- Optional Redemption"
                                 for more information.

Covenants.....................   The terms of the new notes will restrict our
                                 ability to:

                                 - incur liens on our property;

                                 - enter into any sale and lease-back
                                   transactions; and

                                 - consolidate or merge or sell assets.

                                 These limitations are subject to a number of
                                 important qualifications and exceptions which
                                 are described in "Description of Notes -- Terms
                                 and Conditions of the Notes -- Covenants."

Events of Default.............   If there is an event of default on the notes,
                                 the principle amount of the notes plus accrued
                                 interest, if any, may be declared immediately
                                 due and payable in specified circumstances. See
                                 "Description of Notes -- Terms and Conditions
                                 of the Notes -- Events of Default."

                                  RISK FACTORS

     You should carefully consider all of the information contained in this
prospectus before deciding to tender your old notes in the exchange offer. In
particular, you should carefully review the specific factors described below
under the caption "Risk Factors," which contain important information about us
and the risks that may affect our business.

                                        6


                                  RISK FACTORS

     You should consider carefully the following factors, as well as the other
information set forth or incorporated by reference in the prospectus (including
the risks and other disclosure that are presented in our Annual Report on Form
10-K for the year ended December 31, 2001), before tendering your old notes in
the exchange offer. When we use the term "notes" in this prospectus, the term
includes the old notes and the new notes.

HOLDERS WHO FAIL TO EXCHANGE THEIR OLD NOTES WILL CONTINUE TO BE SUBJECT TO
RESTRICTIONS ON TRANSFER.

     If you do not exchange your old notes for new notes in the exchange offer,
you will continue to be subject to the restrictions on transfer of your old
notes described in the legend on the certificates for your old notes. The
restrictions on transfer of your old notes arise because we issued the old notes
under exemptions from, or in transactions not subject to, the registration
requirements of the Securities Act and applicable state securities laws. In
general, you may only offer or sell the old notes if they are registered under
the Securities Act and applicable state securities laws, or are offered and sold
under an exemption from these requirements. We do not plan to register any sale
of the old notes under the Securities Act unless required to do so under the
Registration Rights Agreement. For further information regarding the
consequences of tendering your old notes in the exchange offer, see the
discussions below under the captions "The Exchange Offer -- Consequences of
Exchanging or Failing to Exchange Old Notes" and "Material United States Federal
Income Tax Considerations."

     We believe that new notes issued in exchange for old notes pursuant to the
exchange offer may be offered for resale, resold or otherwise transferred by you
without registering the new notes under the Securities Act or delivering a
prospectus so long as you (1) are not one of our "affiliates," which is defined
in Rule 405 of the Securities Act; (2) acquire the new notes in the ordinary
course of your business and, (3) unless you are a broker dealer, you do not have
any arrangement or understanding with any person to participate in the
distribution of the new notes. Our belief is based on interpretations by the
SEC's staff in no-action letters issued to third parties. Please note that the
SEC has not considered our exchange offer in the context of a no-action letter,
and the SEC's staff may not make a similar determination with respect to our
exchange offer.

     Unless you are a broker-dealer, you must acknowledge that you are not
engaged in, and do not intend to engage in, a distribution of the new notes and
that you have no arrangement or understanding to participate in a distribution
of the new notes. If you are one of our affiliates, or you are engaged in,
intend to engage in or have any arrangement or understanding with respect to,
the distribution of new notes acquired in the exchange offer, you (1) should not
rely on our interpretations of the position of the SEC's staff, (2) will not be
permitted or entitled to tender the old notes in the exchange offer and (3) must
comply with the registration and prospectus delivery requirement of the
Securities Act in connection with any resale transaction.

     If you are a broker-dealer and receive new notes for your own account
pursuant to the exchange offer, you must acknowledge that you will deliver a
prospectus in connection with any resale of the new notes. The letter of
transmittal states that by so acknowledging and by delivering a prospectus, you
will not be deemed to admit that you are an "underwriter" within the meaning of
the Securities Act. If you are a broker-dealer, you may use this prospectus, as
it may be amended or supplemented from time to time, in connection with the
resale of new notes received in exchange for old notes acquired by you as a
result of market-making or other trading activities. For a period of 180 days
after the expiration or termination of the exchange offer, we will make this
prospectus available to any broker-dealer for use in connection with any resale.
See "Plan of Distribution."

     In addition, you may offer or sell the new notes in certain jurisdictions
only if they have been registered or qualified for sale there, or an exemption
from registration or qualification is available and is complied with. Subject to
the limitations specified in the registration rights agreements relating to the
old notes, we will register or qualify the new notes for offer or sale under the
securities laws of any jurisdictions that you reasonably request in writing.
Unless you request that the sale of the new notes be
                                        7


registered or qualified in a jurisdiction, we currently do not intend to
register or qualify the sale of the new notes in any jurisdiction.

YOU MAY FIND IT DIFFICULT TO SELL YOUR NOTES.

     There is no established trading market for the new notes or the old notes.
We do not intend to apply for listing of the new notes on any national
securities exchange or for quotation through The Nasdaq National Market. The
liquidity of any market for the new notes will depend upon the number of holders
of the new notes, our performance, the market for similar securities, the
interest of securities dealers in making a market in the new notes and other
factors relating to us. A liquid trading market may not develop for the new
notes. In addition, to the extent old notes are tendered and accepted in the
exchange offer, the trading market, if any, for the old notes would be adversely
affected.

YOU MUST COMPLY WITH THE EXCHANGE OFFER PROCEDURES IN ORDER TO RECEIVE NEW,
FREELY TRADABLE NOTES.

     Subject to the conditions set forth under "The Exchange Offer -- Conditions
to the Exchange Offer," delivery of new notes in exchange for old notes tendered
and accepted for exchange pursuant to the exchange offer will be made only after
timely receipt by the exchange agent of the following:

     - certificates for old notes or a book-entry confirmation of a book-entry
       transfer of old notes into the exchange agent's account at The Depository
       Trust Company, New York, New York as depository, including an agent's
       message (as defined) if the tendering holder does not deliver a letter of
       transmittal;

     - a completed signed letter of transmittal (or facsimile thereof), with any
       required signature guarantees, or, in the case of a book-entry transfer,
       an agent's message in lieu of the letter of transmittal; and

     - any other documents required by the letter of transmittal.

     Therefore, holders of old notes who would like to tender old notes in
exchange for new notes should be sure to allow enough time for the old notes to
be delivered on time. We are not required to notify you of defects or
irregularities in tenders of old notes for exchange. Old notes that are not
tendered or that are tendered but we do not accept for exchange will, following
consummation of the exchange offer, continue to be subject to the existing
transfer restrictions under the Securities Act and, upon consummation of the
exchange offer, certain registration and other rights under the registration
rights agreement will terminate. See "The Exchange Offer -- Procedures for
Tendering Old Notes" and "The Exchange Offer -- Consequences of Exchanging or
Failing to Exchange Old Notes."

SOME HOLDERS WHO EXCHANGE THEIR NOTES MAY BE DEEMED TO BE UNDERWRITERS.

     If you exchange your old notes in the exchange offer for the purpose of
participating in a distribution of the new notes, you may be deemed to have
received restricted securities and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction.

                                        8


                                USE OF PROCEEDS

     We will not receive any proceeds from the exchange offer. In consideration
for issuing the new notes as contemplated in this prospectus, we will receive in
exchange outstanding old notes in like principal amount. We will cancel all old
notes surrendered in exchange for new notes in the exchange offer.

</Table>

     For purposes of computing the ratio of earnings to fixed charges, earnings
are divided by fixed charges. "Earnings" represent the aggregate of (a) our
pre-tax income, adjusted for distributed income of equity investees, and (b)
fixed charges, net of interest capitalized. "Fixed charges" represent interest
(whether expensed or capitalized), the amortization of total debt premium,
discount and expense and that portion of rentals considered to be representative
of the interest factor.

                               THE EXCHANGE OFFER

TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES

     On July 3, 2002, we issued an aggregate principal amount of $325 million of
our 8 7/8% Senior Notes due July 15, 2012 in a private placement to Salomon
Smith Barney Inc. and other institutions as initial purchasers. Salomon Smith
Barney and the other institutions then resold the notes in an unregistered
offering pursuant to Rule 144A and Regulation S under the Securities Act. The
old notes were issued and the new notes will be issued, under an indenture
relating to the notes, dated July 3, 2002. The trustee under the indenture was
originally Citibank, N.A. Citibank, N.A. has been replaced as trustee by Wells
Fargo Bank, N.A. We sold the old notes to Salomon Smith Barney Inc. and other
institutions, as initial purchasers, under a purchase agreement, dated June 28,
2002, by and between Salomon Smith Barney Inc., the other institutions parties
thereto and us. When we sold the old notes to Salomon Smith Barney Inc. and the
other institutions we also signed a registration rights agreement in which we
agreed to exchange all the issued and outstanding old notes for a like principal
amount of our new notes. The terms of the new notes are substantially identical
to those of the outstanding old notes, except that the transfer restrictions and
registration rights relating to the old notes do not apply to the new notes.

     Subject to the terms and conditions set forth in this prospectus and in the
letter of transmittal, we are offering to exchange up to $325 million in
aggregate principal amount of our 8 7/8% Series B Senior Notes due July 15, 2012
for an equal amount of our outstanding 8 7/8% Series A Senior Notes due July 15,
2012.

     This prospectus and the enclosed letter of transmittal constitute an offer
to exchange new notes for all of the issued and outstanding old notes. This
exchange offer is being extended to all holders of the old notes. As of the date
of this prospectus, $325 million aggregate principal amount of 8 7/8% Series A
Senior Notes due July 15, 2012 are outstanding. This prospectus and the enclosed
letter of transmittal are first being sent on or about             , 2002, to
all holders of old notes known to us. Subject to the conditions listed below, we
will accept for exchange all old notes which are properly tendered on or prior
to the expiration of the exchange offer and not withdrawn as permitted below.
The exchange offer will expire at 5:00 p.m., New York City time, on           ,
2003. However, if we, in our sole discretion, extend the period of time during
which the exchange offer is open, the exchange offer will expire at the latest
time and date to which we extend the exchange offer. Our obligation to accept
old notes for exchange in the exchange offer is subject to the conditions listed
below under the caption "-- Conditions to the Exchange Offer."

     We expressly reserve the right, at any time and from time to time, to
extend the period of time during which the exchange offer is open, and thereby
delay acceptance for exchange of any old notes. If we elect to extend the period
of time during which the exchange offer is open, we will give you oral or
written notice of the extension and delay, as described below. During any
extension of the exchange offer, all old notes previously tendered and not
withdrawn will remain subject to the exchange offer and may be accepted for
exchange by us. We will return to the registered holder, at our expense, any old
notes not accepted for exchange as promptly as practicable after the expiration
or termination of the exchange offer. In the case of an extension, we will issue
a press release or other public announcement no later than 9:00 a.m., New York
City time, on the next business day after the previously scheduled expiration of
the exchange offer.

     We expressly reserve the right to amend or terminate the exchange offer,
and not to accept for exchange any old notes not previously accepted for
exchange if any of the events described below under the caption "-- Conditions
to the Exchange Offer" should occur. We will give you oral or written notice of
any amendment, termination or non-acceptance as promptly as practicable.

     Following completion of the exchange offer, we may, in our sole discretion,
commence one or more additional exchange offers to those old note holders who
did not exchange their old notes for new notes. The terms of these additional
exchange offers may differ from those applicable to this exchange offer. We may
use this prospectus, as amended or supplemented from time to time, in connection
with any additional exchange offers. These additional exchange offers may take
place from time to time until all
                                        11


outstanding old notes have been exchanged for new notes, subject to the terms
and conditions contained in the prospectus and letter of transmittal we will
distribute in connection with the additional exchange offers.

PROCEDURES FOR TENDERING OLD NOTES

     Old notes tendered in the exchange offer must be in denominations of $1,000
principal amount and any integral multiple thereof.

     When you tender your old notes, and we accept the old notes, this will
constitute a binding agreement between you and us subject to the terms and
conditions set forth in this prospectus and the enclosed letter of transmittal.
Unless you comply with the procedures described below under the caption
"-- Guaranteed Delivery Procedures," you must do one of the following on or
prior to the expiration of the exchange offer to participate in the exchange
offer:

     - tender your old notes by sending the certificates for your old notes, in
       proper form for transfer, a properly completed and duly executed letter
       of transmittal, with any required signature guarantees, and all other
       documents required by the letter of transmittal, to Wells Fargo Bank,
       N.A., as exchange agent, at one of the addresses listed below under the
       caption "-- Exchange Agent"; or

     - tender your old notes by using the book-entry procedures described below
       under the caption "-- Book-Entry Transfer" and transmitting a properly
       completed and duly executed letter of transmittal, with any required
       signature guarantees, or an agent's message instead of the letter of
       transmittal, to Wells Fargo Bank, N.A., as exchange agent, at one of the
       addresses listed below under the caption "-- Exchange Agent."

     In order for a book-entry transfer to constitute a valid tender of your old
notes in the exchange offer, the exchange agent must receive a confirmation of
book-entry transfer of your old notes into the exchange agent's account at The
Depository Trust Company prior to the expiration of the exchange offer. The term
"agent's message" means a message, transmitted by The Depository Trust Company
and received by the exchange agent and forming a part of the book-entry
confirmation, which states that The Depository Trust Company has received an
express acknowledgment from you that you have received and have agreed to be
bound by the letter of transmittal. If you use this procedure, we may enforce
the letter of transmittal against you.

     THE METHOD OF DELIVERY OF CERTIFICATES FOR OLD NOTES, LETTERS OF
TRANSMITTAL, AGENT'S MESSAGES AND ALL OTHER REQUIRED DOCUMENTS IS AT YOUR
ELECTION. IF YOU DELIVER YOUR OLD NOTES BY MAIL, WE RECOMMEND REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. IN ALL CASES, YOU SHOULD ALLOW
SUFFICIENT TIME TO ASSURE TIMELY DELIVERY. DO NOT SEND CERTIFICATES FOR OLD
NOTES, LETTERS OF TRANSMITTAL OR AGENT'S MESSAGES TO US.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless you are either a registered old note
holder and have not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on the letter of transmittal or you are
exchanging old notes for the account of an eligible guarantor institution. An
eligible guarantor institution means:

     - Banks (as defined in Section 3(a) of the Federal Deposit Insurance Act);

     - Brokers, dealers, municipal securities dealers, municipal securities
       brokers, government securities dealers and government securities brokers
       (as defined in the Exchange Act);

     - Credit unions (as defined in Section 19B(1)(A) of the Federal Reserve
       Act);

     - National securities exchanges, registered securities associations and
       clearing agencies (as these terms are defined in the Exchange Act); and

     - Savings associations (as defined in Section 3(b) of the Federal Deposit
       Insurance Act).

                                        12


     If signatures on a letter of transmittal or a notice of withdrawal are
required to be guaranteed, the guarantor must be an eligible guarantor
institution. If you plan to sign the letter of transmittal but you are not the
registered holder of the old notes -- which term, for this purpose, includes any
participant in The Depository Trust Company's system whose name appears on a
security position listing as the owner of the old notes -- you must have the old
notes signed by the registered holder of the old notes and that signature must
be guaranteed by an eligible guarantor institution. You may also send a separate
instrument of transfer or exchange signed by the registered holder and
guaranteed by an eligible guarantor institution, but that instrument must be in
a form satisfactory to us in our sole discretion. In addition, if a person or
persons other than the registered holder or holders of old notes signs the
letter of transmittal, certificates for the old notes must be endorsed or
accompanied by appropriate bond powers, in either case signed exactly as the
name or names of the registered holder or holders that appear on the
certificates for old notes.

     All questions as to the validity, form, eligibility -- including time of
receipt -- and acceptance of old notes tendered for exchange will be determined
by us in our sole discretion. Our determination will be final and binding. We
reserve the absolute right to reject any and all tenders of old notes improperly
tendered or to not accept any old notes, the acceptance of which might be
unlawful as determined by us or our counsel. We also reserve the absolute right
to waive any defects or irregularities or conditions of the exchange offer as to
any old notes either before or after the expiration of the exchange
offer -- including the right to waive the ineligibility of any holder who seeks
to tender old notes in the exchange offer. Our interpretation of the terms and
conditions of the exchange offer as to any particular old notes either before or
after the expiration of the exchange offer -- including the terms and conditions
of the letter of transmittal and the accompanying instructions -- will be final
and binding. Unless waived, any defects or irregularities in connection with
tenders of old notes for exchange must be cured within a reasonable period of
time, as determined by us. Neither we, Wells Fargo Bank, N.A., as exchange
agent, nor any other person has any duty to give notification of any defect or
irregularity with respect to any tender of old notes for exchange, nor will we
have any liability for failure to give this notification.

     If you are a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation, or act in a similar fiduciary or representative
capacity, and wish to sign the letter of transmittal or any certificates for old
notes or bond powers, you must indicate your status when signing. If you are
acting in any of these capacities, you must submit proper evidence satisfactory
to us of your authority to so act unless we waive this requirement.

     By tendering your old notes, you represent to us:

     - that you are not our "affiliate" as defined in Rule 405 under the
       Securities Act;

     - that any new notes you receive in the exchange offer are being acquired
       by you in the ordinary course of your business;

     - that at the time of the commencement of the exchange offer, you do not
       have any arrangement or understanding with any person to participate in
       the distribution of the new notes, as defined in the Securities Act, in
       violation of the Securities Act;

     - if you are not a participating broker-dealer, that you are not engaged
       in, and do not intend to engage in, the distribution of the new notes, as
       defined in the Securities Act; and

     - if you are a participating broker-dealer, that you will receive the new
       notes for your own account in exchange for old notes that were acquired
       by you as a result of your market-making or other trading activities and
       that you will deliver a prospectus in connection with any resale of the
       new notes you receive. As used in this prospectus, a "participating
       broker-dealer" is a broker-dealer that receives new notes for its own
       account in exchange for old notes that it acquired as a result of
       market-making or other trading activities. The SEC has taken the position
       that participating broker-dealers may fulfill their prospectus delivery
       requirements with respect to resales of the new notes -- other than a
       resale of an unsold allotment from the original sale of the old
       notes -- by

                                        13


       delivering this prospectus to prospective purchasers. For further
       information regarding participating broker-dealers and the prospectus
       delivery requirement, see "Plan of Distribution."

ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES

     Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the expiration of the exchange offer, all old
notes properly tendered and will issue the new notes promptly after the
acceptance of the old notes. For purposes of the exchange offer, we will be
deemed to have accepted properly tendered old notes for exchange when, as and if
we have given oral or written notice of acceptance to Wells Fargo Bank, N.A., as
exchange agent, with written confirmation of any oral notice to be given
promptly after any oral notice.

     For each outstanding note accepted for exchange in the exchange offer, the
holder of the old note will receive a new note having a principal amount at
maturity equal to that of the surrendered old note. Interest on the new note
will accrue:

     - from the later of the last date to which interest was paid on the old
       note surrendered in the exchange for the new note or if the old note is
       surrendered for exchange on a date in a period which includes the record
       date for an interest payment date to occur on or after the date of the
       exchange and as to which interest will be paid, the date to which
       interest will be paid on such interest payment date; or

     - if no interest has been paid on the old note, from and including July 3,
       2002.

     Payments of interest, if any, on old notes that were exchanged for new
notes will be made on each January 15 and July 15 during which the new notes are
outstanding to the person who, at the close of business on the record date next
preceding the interest payment date, is the registered holder of the old notes
if the record date occurs prior to the exchange, or is the registered holder of
the new notes if the record date occurs on or after the date of the exchange,
even if the old notes are cancelled after the record date and on or before the
interest payment date.

     In addition, if

     - we do not file a registration statement on or prior to September 16,
       2002,

     - this registration statement is not declared effective on or prior to
       October 31, 2002 or the exchange offer is not completed within 60 days
       after the registration statement is declared effective,

     - the exchange offer is not consummated by December 30, 2002,

     - we are obligated to file a shelf registration statement and we fail to do
       so prior to the 75th day after the obligation arises or the shelf
       registration statement is not declared effective prior to the 60th day
       after the date of filing, or

     - if the shelf registration statement ceases to be effective or usable,

(each a "Registration Default") then we agree to pay each holder of transfer
restricted securities affected thereby liquidated damages in an amount equal to
0.25% per annum of the principal amount of transfer restricted securities held
by such holder for the first 90-day period immediately following the occurrence
of a Registration Default, increasing to 0.50% per annum thereafter, from and
including the date on which any such registration default shall occur. We shall
not be required to pay liquidated damages for more than one Registration Default
at any given time. Following the cure of all Registration Defaults, the accrual
of liquidated damages will cease.

     We did not file this registration statement on or prior to September 16,
2002, nor was it declared effective on or prior to October 31, 2002. Therefore,
liquidated damages have been accruing since September 17, 2002. The liquidated
damages will cease to accrue as of the date of this prospectus. However, since
the exchange offer will not be consummated by December 30, 2002, liquidated
damages will begin to accrue from December 31, 2002 until such time as the
exchange offer is consummated.

                                        14


     In all cases, the issuance of new notes in exchange for old notes will be
made only after Wells Fargo Bank, N.A., as exchange agent, timely receives
either certificates for all physically tendered old notes, in proper form for
transfer, or a book-entry confirmation of transfer of the old notes into the
exchange agent's account at The Depository Trust Company, as the case may be, a
properly completed and duly executed letter of transmittal, with any required
signature guarantees, and all other required documents or, in the case of a
book-entry confirmation, a properly completed and duly executed letter of
transmittal, with any required signature guarantees, or an agent's message
instead of the letter of transmittal. If for any reason we do not accept any
tendered old notes or if old notes are submitted for a greater principal amount
than the holder desires to exchange, we will return the unaccepted or
non-exchanged old notes without expense to the registered holder. In the case of
old notes tendered by book-entry transfer into the exchange agent's account at
The Depository Trust Company by using the book-entry procedures described below,
the unaccepted or non-exchanged old notes will be credited to an account
maintained with The Depository Trust Company. Any old notes to be returned to
the holder will be returned as promptly as practicable after the expiration or
termination of the exchange offer.

BOOK-ENTRY TRANSFER

  BOOK-ENTRY, DELIVERY AND FORM

     The exchange agent will make a request to establish an account for the old
notes at DTC for purposes of the exchange offer within two business days after
the date of this prospectus. Any financial institution that is a participant in
DTC's systems must make book-entry delivery of old notes by causing DTC to
transfer those old notes into the exchange agent's account at DTC in accordance
with DTC's procedure for transfer. The participant should transmit its
acceptance to DTC at or prior to the expiration time or comply with the
guaranteed delivery procedures described below. DTC will verify this acceptance,
execute a book-entry transfer of the tendered old notes into the exchange
agent's account at DTC and then send to the exchange agent confirmation of this
book-entry transfer. The confirmation of this book-entry transfer will include
an agent's message confirming that DTC has received an express acknowledgment
from this participant that this participant has received and agrees to be bound
by the letter of transmittal and that we may enforce the letter of transmittal
against this participant.

     Delivery of new notes issued in the exchange offer may be effected through
book-entry transfer at DTC. However, the letter of transmittal or facsimile of
it or an agent's message, with any required signature guarantees and any other
required documents, must:

     - be transmitted to and received by the exchange agent at the address
       listed under "-- Exchange Agent" at or prior to the expiration time; or

     - comply with the guaranteed delivery procedures described below.

     Delivery of documents to DTC in accordance with DTC's procedures does not
constitute delivery to the exchange agent.

GUARANTEED DELIVERY PROCEDURES

     If you are a registered holder of the old notes and wish to tender your old
notes, but

     - the certificates for the old notes are not immediately available,

     - time will not permit your certificates for the old notes or other
       required documents to reach Wells Fargo Bank, N.A., as exchange agent,
       before the expiration of the exchange offer, or

     - the procedure for book-entry transfer cannot be completed before the
       expiration of the exchange offer,

                                        15


     then you may effect a tender of your old notes if:

     - the tender is made through an eligible guarantor institution;

     - prior to the expiration of the exchange offer, the exchange agent
       receives from an eligible guarantor institution a properly completed and
       duly executed notice of guaranteed delivery, substantially in the form we
       have provided, setting forth your name and address, and the amount of old
       notes you are tendering and stating that the tender is being made by
       notice of guaranteed delivery. These documents may be sent by overnight
       courier, registered or certified mail or facsimile transmission. If you
       elect to use this procedure, you must also guarantee that within three
       New York Stock Exchange, Inc. trading days after the date of execution of
       the notice of guaranteed delivery, the certificates for all physically
       tendered old notes, in proper form for transfer, or a book-entry
       confirmation of transfer of the old notes into the exchange agent's
       account at The Depository Trust Company, as the case may be, a properly
       completed and duly executed letter of transmittal, with any required
       signature guarantees, and all other required documents or, in the case of
       a book-entry confirmation, a properly completed and duly executed letter
       of transmittal, with any required signature guarantees, or an agent's
       message instead of the letter of transmittal, will be deposited by the
       eligible guarantor institution with the exchange agent; and

     - the exchange agent receives the certificates for all physically tendered
       old notes, in proper form for transfer, or a book-entry confirmation of
       transfer of the old notes into the exchange agent's account at The
       Depository Trust Company, as the case may be, a properly completed and
       duly executed letter of transmittal, with any required signature
       guarantees, and all other required documents or, in the case of a
       book-entry confirmation, a properly completed and duly executed letter of
       transmittal, with any required signature guarantees, or an agent's
       message instead of the letter of transmittal, in each case, within three
       New York Stock Exchange, Inc. trading days after the date of execution of
       the notice of guaranteed delivery.

WITHDRAWAL RIGHTS

  You may withdraw tenders of old notes at any time prior to the expiration of
  the exchange offer.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by Wells Fargo Bank, N.A., as exchange agent, prior to the expiration
of the exchange offer at one of the addresses listed below under the caption
"-- Exchange Agent." Any notice of withdrawal must:

     - specify the name of the person who tendered the old notes to be
       withdrawn;

     - identify the old notes to be withdrawn, including the principal amount of
       the old notes;

     - contain a statement that the holder is withdrawing its election to have
       the old notes exchanged;

     - be signed by the holder in the same manner as the original signature on
       the letter of transmittal by which the old notes were tendered, including
       any required signature guarantees, or be accompanied by documents of
       transfer to have the trustee with respect to the old notes register the
       transfer of the old notes in the name of the person withdrawing the
       tender; and

     - specify the name in which the old notes are registered, if different from
       that of the depositor.

     If certificates for old notes have been delivered or otherwise identified
to the exchange agent, then, prior to the release of the certificates, the
withdrawing holder must also submit the serial numbers of the particular
certificates to be withdrawn and a signed notice of withdrawal with signatures
guaranteed by an eligible guarantor institution unless the holder is an eligible
guarantor institution. If old notes have been tendered using the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at The Depository Trust Company to be credited
with the withdrawn old notes and otherwise comply with the procedures of the
book-entry transfer facility. All questions as to the validity, form and
eligibility -- including time of receipt -- of these notices will be determined
by us. Our determination will be final and binding.

                                        16


     Any old notes so withdrawn will be deemed not to have been validly tendered
for exchange for purposes of the exchange offer. Any old notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the registered holder without cost to that holder as soon as
practicable after withdrawal, non-acceptance of tender or termination of the
exchange offer. In the case of old notes tendered by book-entry transfer into
the exchange agent's account at The Depository Trust Company by using the
book-entry transfer procedures described above, any withdrawn or unaccepted old
notes will be credited to the tendering holder's account at The Depository Trust
Company. Properly withdrawn old notes may be retendered at any time on or prior
to the expiration of the exchange offer by following one of the procedures
described above under "-- Procedures for Tendering Old Notes."

CONDITIONS TO THE EXCHANGE OFFER

     Notwithstanding any other provision of the exchange offer, we will not be
required to accept any old notes for exchange or to issue any new notes in
exchange for old notes, and we may terminate or amend the exchange offer if, at
any time before the acceptance of the old notes for exchange or the exchange of
new notes for old notes, any of the following events occurs:

     - the exchange offer is determined to violate any applicable law or any
       applicable interpretation of the staff of the SEC;

     - an action or proceeding is pending or threatened in any court or by any
       governmental agency that might materially impair our ability to proceed
       with the exchange offer;

     - any material adverse development occurs in any existing legal action or
       proceeding involving us;

     - we do not receive any governmental approval we deem necessary for the
       completion of the exchange offer; or

     - any of the conditions precedent to our obligations under the registration
       rights agreement are not fulfilled.

     These conditions are for our benefit only and we may assert them regardless
of the circumstances giving rise to any condition. We may also waive any
condition in whole or in part at any time in our sole discretion. Our failure at
any time to exercise any of the foregoing rights will not constitute a waiver of
that right and each right is an ongoing right that we may assert at any time.

     In addition, we will not accept any old notes for exchange or issue any new
notes in exchange for old notes, if at the time a stop order is threatened or in
effect which relates to:

     - the registration statement of which this prospectus forms a part; or

     - the qualification under the Trust Indenture Act of 1939 of the indenture
       under which the old notes were issued and the new notes will be issued.

FEES AND EXPENSES

     The principal solicitation is being made by mail by Wells Fargo Bank, N.A.,
as exchange agent. We will pay the exchange agent customary fees for its
services, reimburse the exchange agent for its reasonable out-of-pocket expenses
incurred in connection with the provision of these services and pay other
registration expenses, including fees and expenses of the trustee under the
indenture relating to the notes, filing fees, blue sky fees and printing and
distribution expenses. We will not make any payment to brokers, dealers or
others soliciting acceptances of the exchange offer.

     Additional solicitation may be made by telephone, facsimile or in person by
our and our affiliates' officers and regular employees and by persons so engaged
by the exchange agent.

TRANSFER TAXES

     You will not be obligated to pay any transfer taxes in connection with the
tender of old notes in the exchange offer unless you instruct us to register new
notes in the name of, or request that old notes not tendered or not accepted in
the exchange offer be returned to, a person other than the registered tendering
holder. In those cases, you will be responsible for the payment of any
applicable transfer tax.

CONSEQUENCES OF EXCHANGING OR FAILING TO EXCHANGE OLD NOTES

     If you do not exchange your old notes for new notes in the exchange offer,
your old notes will continue to be subject to the provisions of the indenture
relating to the notes regarding transfer and exchange of the old notes and the
restrictions on transfer of the old notes described in the legend on your
certificates. These transfer restrictions are required because the old notes
were issued under an exemption from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In general, the old notes may not be offered or sold, unless registered
under the Securities Act, except under an exemption from, or in a transaction
not subject to, the Securities Act and applicable state securities laws. We do
not plan to register the old notes under the Securities Act unless required to
do so under the Registration Rights Agreement. Based on interpretations by the
staff of the SEC, as set forth in no-action letters issued to third parties, we
believe that the new notes you receive in the exchange offer may be offered for
resale, resold or otherwise transferred without compliance with the

                                        18


registration and prospectus delivery provisions of the Securities Act. However,
you will not be able to freely transfer the new notes if:

     - you are our "affiliate," as defined in Rule 405 under the Securities Act;

     - you are not acquiring the new notes in the exchange offer in the ordinary
       course of your business;

     - you have an arrangement or understanding with any person to participate
       in the distribution of the new notes, as defined in the Securities Act,
       you will receive in the exchange offer; or

     - you are a participating broker-dealer.

     We do not intend to request the SEC to consider, and the SEC has not
considered, the exchange offer in the context of a similar no-action letter. As
a result, we cannot guarantee that the staff of the SEC would make a similar
determination with respect to the exchange offer as in the circumstances
described in the no-action letters discussed above. Each holder, other than a
broker-dealer, must acknowledge that it is not engaged in, and does not intend
to engage in, a distribution of new notes and has no arrangement or
understanding to participate in a distribution of new notes. If you are our
affiliate, are engaged in or intend to engage in a distribution of the new notes
or have any arrangement or understanding with respect to the distribution of the
new notes you will receive in the exchange offer, you

     - may not rely on the applicable interpretations of the staff of the SEC
       and

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any resale transaction involving
       the new notes.

     If you are a participating broker-dealer, you must acknowledge that you
will deliver a prospectus in connection with any resale of the new notes. In
addition, to comply with state securities laws, you may not offer or sell the
new notes in any state unless they have been registered or qualified for sale in
that state or an exemption from registration or qualification is available and
is complied with. The offer and sale of the new notes to "qualified
institutional buyers" -- as defined in Rule 144A of the Securities Act -- is
generally exempt from registration or qualification under state securities laws.
We do not plan to register or qualify the sale of the new notes in any state
where an exemption from registration or qualification is required and not
available.

                              DESCRIPTION OF NOTES

     The old notes were issued and the new notes will be issued under an
indenture dated as of July 3, 2002. The trustee under the indenture was
originally Citibank, N.A. Citibank, N.A. has been replaced as trustee by Wells
Fargo Bank, N.A. This summary is qualified in its entirety by reference to the
indenture, a copy of which is available from us upon request.

     The old notes were and the new notes will be our unsecured and
unsubordinated obligations ranking equally with our other outstanding unsecured
and unsubordinated indebtedness. At September 30, 2002, we had outstanding
approximately $1.1 billion of unsecured and unsubordinated indebtedness. The
indenture contains no restrictions on the amount of additional secured or
unsecured indebtedness that we may issue.

TERMS AND CONDITIONS OF THE NOTES

     The notes will mature on July 15, 2012. The notes will bear interest from
the date of original issuance of the old notes or, if interest has already been
paid, from the date it was most recently paid, at the rate of 8.875% per year.
Interest will be payable semi-annually on January 15 and July 15 of each year,
beginning January 15, 2003, to the person in whose names the notes are
registered at the close of business on the preceding January 1 and July 1,
respectively, subject to certain exceptions. Interest on the notes will be
computed on the basis of a 360-day year comprised of twelve 30-day months.

     We may, without the consent of the holders of the notes, issue additional
notes having the same ranking and the same interest rate, maturity and other
terms as the old notes or the new notes. Any additional notes will, together
with the previously outstanding notes, constitute a single series of the notes
under the indenture. No additional notes may be issued if an event of default
has occurred with respect to the notes.

     The old notes are, and the new notes will initially be, issued only in
registered, book-entry form, in denominations of $1,000 and any integral
multiples of $1,000 as described under "The Exchange Offer -- Book-Entry
Transfer." We will issue global notes in denominations that together equal the
total principal amount of the outstanding notes.

  OPTIONAL REDEMPTION

     The old notes are, and the new notes will be redeemable, in whole at any
time, or in part, from time to time, at our option, at a redemption price equal
to the greater of:

     - 100% of the principal amount of the notes then outstanding to be
       redeemed, or

     - the sum of the present values of the remaining scheduled payments of
       principal and interest thereon from the redemption date to the maturity
       date computed by discounting such payments to the redemption date on a
       semi-annual basis (assuming a 360-day year consisting of twelve 30-day
       months) at a rate equal to the sum of 50 basis points plus the Adjusted
       Treasury Rate on the third business day prior to the redemption date, as
       calculated by an Independent Investment Banker.

     "Adjusted Treasury Rate" means:

     - 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 contains yields on actively traded U.S. 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
       remaining term of the notes, yields for the two published maturities most
       closely corresponding to the Comparable Treasury Issue will be determined
       and the Adjusted Treasury Rate will be interpolated or extrapolated from
       such yields on a straight line basis, rounding to the nearest month); or

                                        20


     - 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 annum 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.

     "Comparable Treasury Issue" means the U.S. Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining
term of the notes 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 the notes or,
if, in the reasonable judgment of the Independent Investment Banker, there is no
such security, then the Comparable Treasury Issue will mean the U.S. Treasury
security or securities selected by an Independent Investment Banker as having an
actual or interpolated maturity or maturities comparable to the remaining term
of the notes.

     "Comparable Treasury Price" means (1) the average of five Reference
Treasury Dealer Quotations for the applicable redemption date, after excluding
the highest and lowest Reference Treasury Dealer Quotations, or (2) if the
Independent Investment Banker obtains fewer than five such Reference Treasury
Dealer Quotations, the average of all such quotations.

     "Independent Investment Banker" means Salomon Smith Barney Inc. or any
successor firm, or if any such firm is unwilling or unable to serve as such, an
independent investment and banking institution of national standing appointed by
us.

     "Reference Treasury Dealer Quotations" means the average, as determined by
the Independent Investment Banker, 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 Independent Investment Banker and the
Trustee at 5:00 p.m., New York City time, on the third business day preceding
such redemption date.

     We will mail notice of redemption at least 30 days but not more than 60
days before the applicable redemption date to each holder of the notes to be
redeemed. If we elect to partially redeem the notes, the Trustee will select in
a fair and appropriate manner the notes to be redeemed.

     Upon the payment of the redemption price, plus accrued and unpaid interest,
if any, and liquidated damages, if any, to the date of redemption, interest will
cease to accrue on and after the applicable redemption date on the notes or
portions thereof called for redemption.

  COVENANTS

     Liens.  The indenture refers to any of our instruments securing
indebtedness, such as a mortgage, pledge, lien, security interest or encumbrance
on any of our property, as a "mortgage." The indenture further provides that,
subject to certain exceptions, we will not, nor will we permit any subsidiary
to, issue, assume or guarantee any indebtedness secured by a mortgage unless we
provide equal and proportionate security for the notes. Among these exceptions
are:

     - purchase money mortgages;

     - preexisting mortgages on any property acquired or constructed by us or a
       subsidiary;

     - mortgages created within one year after completion of such acquisition or
       construction or within one year of commencement of full operation of such
       property;

     - mortgages created on any contract for the sale of products or services
       related to the operation or use of any property acquired or constructed
       within one year after the later of completion of such acquisition or
       construction or commencement of full operation of such property;

     - mortgages on property of a subsidiary existing at the time it became our
       subsidiary; and

                                        21


     - mortgages, other than as specifically excepted, in an aggregate amount
       which, at the time of, and after giving effect to, the incurrence does
       not exceed five percent of our Consolidated Net Tangible Assets, as
       defined in the indenture.

     Limitation on Sale and Lease-Back Transactions.  We will not, and we will
not permit any of our subsidiaries to, enter into any arrangement with any
person providing for the leasing by us or any of our subsidiaries of any
Principal Property, acquired or placed into service more than 180 days prior to
such arrangement (except for leases of three years or less), whereby such
property has been or is to be sold or transferred by us or any of our
subsidiaries to such person (any such transaction being referred to as a "Sale
and Lease-Back Transaction"), unless:

     - we or any of our subsidiaries would, at the time of entering into a Sale
       and Lease-Back Transaction, be entitled to incur indebtedness secured by
       a mortgage on the property to be leased in an amount at least equal to
       the Attributable Debt in respect of such transaction without equally and
       ratably securing the Securities pursuant to the covenant described above
       under "-- Liens"; or

     - we shall covenant that we will apply an amount equal to the net proceeds
       from the sale of the Principal Property so leased to the retirement
       (other than any mandatory retirement) of our Funded Indebtedness within
       90 days of the effective date of any such Sale and Lease-Back
       Transaction, provided that the amount to be applied to the retirement of
       our Funded Indebtedness shall be reduced by (a) the principal amount of
       any notes delivered by us to the Trustee within 90 days after such Sale
       and Lease-Back Transaction for retirement and cancellation, and (b) the
       principal amount of Funded Indebtedness, other than notes, voluntarily
       retired by us within 90 days following such Sale and Lease-Back
       Transaction,

provided, further, this covenant shall not apply to, and there shall be excluded
from Attributable Debt in any computation under this covenant, Attributable Debt
with respect to any Sale and Lease-Back Transaction if:

     - such Sale and Lease-Back Transaction is entered into in connection with
       transactions which are part of an industrial development or pollution
       control financing or,

     - the only parties involved in such Sale and Lease-Back Transaction are us
       and/or any of our subsidiaries.

     Notwithstanding the foregoing, we and our subsidiaries may enter into,
create, assume and suffer to exist Sale and Lease-Back Transactions, not
otherwise permitted, if at the time of, and after giving effect to, such Sale
and Lease-Back Transaction, our total consolidated Attributable Debt does not
exceed five percent of our Consolidated Net Tangible Assets.

     "Attributable Debt" means, with respect to any Sale and Lease-Back
Transaction as of any particular time, the present value discounted at the rate
of interest implicit in the terms of the lease of the obligations of the lessee
under such lease for net rental payments during the remaining term of the lease
(including any period for which such lease has been extended or may, at our
option, be extended).

     "Consolidated Net Tangible Assets" means the total assets appearing on a
consolidated balance sheet of us and our consolidated subsidiaries, less:

     (1) intangible assets, unamortized debt discount and expense and stock
         expense and other deferred debits;

     (2) all current and accrued liabilities (other than consolidated Funded
         Indebtedness and capitalized rentals or leases); deferred credits
         (other than deferred investment tax credits), deferred gains and
         deferred income and billings recorded as revenues deferred pending the
         outcome of a rate proceeding (less applicable income taxes) to the
         extent refunds thereof shall not have been finally determined; and

     (3) all reserves (other than for deferred federal income taxes arising from
         timing differences) not already deducted from assets.
                                        22


     "Funded Indebtedness" means any indebtedness which matures more than one
year after the date as of which Funded Indebtedness is being determined less any
such Indebtedness as will be retired through or by means of any deposit or
payment required to be made within one year from such date under any prepayment
provision, sinking fund, purchase fund or otherwise.

     "Principal Property" means any natural gas pipeline, gathering property or
natural gas processing plant located in the United States, except any such
property that in the opinion of our board of directors is not of material
importance to the total business conducted by us and our consolidated
subsidiaries. "Principal Property" shall not include (i) the production or
proceeds from production of gas processing plants or natural gas or petroleum
products in any pipeline or storage field and (ii) any property acquired or
constructed by us or any of our subsidiaries after December 31, 1996.

     Consolidation, Merger, Conveyance of Assets.  The indenture provides, in
general, that we will not consolidate with or merge into any other entity or
convey, transfer or lease our properties and assets substantially as an entirety
to any person, unless:

     - the corporation, limited liability company, limited partnership, joint
       stock company or trust formed by such consolidation or into which we are
       merged or the person which acquires such assets expressly assumes our
       obligations under the indenture and the notes; and

     - immediately after giving effect to such transaction, no event of default,
       and no event which, after notice or lapse of time or both, would become
       an event of default, shall have happened and be continuing.

     Event Risk.  Except for the limitations on liens and consolidations,
mergers and conveyance of assets described above, neither the indenture nor the
notes contain any covenants or other provisions designed to afford holders of
the notes protection in the event of a highly leveraged transaction or change of
control involving us or any restrictions on the amount of additional
indebtedness that we may issue.

  MODIFICATION OF THE INDENTURE

     Without the consent of any holder, we and the trustee may amend or
supplement the indenture or the notes to:

     - cure any ambiguity, omission, defect or inconsistency;

     - comply with the indenture in the case of the merger, consolidation or
       sale or other disposition of all or substantially all of our assets;

     - provide for uncertificated notes in addition to or in place of
       certificated notes;

     - add any additional events of default;

     - provide for the acceptance of a successor trustee;

     - secure the notes pursuant to the requirements under the indenture;

     - comply with any requirements in order to effect or maintain the
       qualification of the indenture under the Trust Indenture Act of 1939;

     - comply with any requirements of the SEC in connection with qualifying the
       indenture under the Trust Indenture Act of 1939;

     - add to our covenants for the benefit of the holders of notes or surrender
       any power conferred upon us; or

     - make any change that does not adversely affect the rights of any holder
       of notes in any material respect.

                                        23


     We and the trustee may take the following actions with the consent of the
holders of at least a majority in principal amount of the notes then
outstanding:

     - add any provisions to the indenture;

     - change in any manner the indenture;

     - eliminate any of the provisions of the indenture; and

     - modify in any way the rights of the holders of the notes.

     These changes must conform to the Trust Indenture Act of 1939. In addition,
without the consent of each holder affected, we may not:

     - reduce the percentage of principal amount of notes whose holders must
       consent to an amendment, supplement or waiver;

     - reduce the rate of or change the time for payment of interest, including
       default interest, on any note;

     - reduce the principal of or change the fixed maturity of any note or alter
       the premium or other provisions with respect to redemption;

     - make any note payable in money or in a place other than that stated in
       the note;

     - impair the right to institute suit for the enforcement of any payment of
       principal of, or premium, if any, or interest on any note;

     - make any change in the percentage of principal amount of notes necessary
       to waive compliance with certain provisions of the indenture; or

     - waive a continuing default or event of default in the payment of
       principal of, or premium, if any, or interest on the notes.

  EVENTS OF DEFAULT

     In general, the indenture defines an event of default with respect to the
notes as being:

     - default in payment of any principal of the notes, either at maturity,
       upon any redemption, by declaration or otherwise;

     - default for 30 days in payment of any interest on the notes unless
       otherwise provided;

     - default for 90 days after written notice in the observance or performance
       of any covenant or warranty in the notes or the indenture other than:

        - default in or breach of a covenant which is dealt with otherwise
          below; or

        - if certain conditions are met, if the events of default described in
          this clause are the result of changes in generally accepted accounting
          principles; or

     - certain events of our bankruptcy, insolvency or reorganization.

     In general, the indenture provides that if an event of default described in
the first three clauses above occurs, the Trustee or the holders of the notes
may then declare the entire principal of all the notes and the interest accrued
on such principal to be due and payable immediately. Such a declaration by the
holders requires the approval of at least 25 percent in principal amount of the
notes then outstanding.

     Upon certain conditions, the holders of a majority in aggregate principal
amount of the notes then outstanding may annul such declarations and waive the
past defaults. However, the majority holders may not annul or waive a continuing
default in payment of principal of, premium, if any, or interest on the notes.

                                        24


     The indenture provides that the holders of the notes will indemnify the
trustee before the trustee exercises any of its rights or powers under the
indenture. This indemnification is subject to the trustee's duty to act with the
required standard of care during a default. The holders of a majority in
aggregate principal amount of the outstanding notes may direct the time, method
and place of:

     - conducting any proceeding for any remedy available to the trustee, or

     - exercising any trust or power conferred on the trustee.

     This right of the holders of the notes is, however, subject to the
provisions in the indenture providing for the indemnification of the trustee and
other specified limitations.

     In general, the indenture provides that holders of the notes may only
institute an action against us under the indenture if the following four
conditions are fulfilled:

     - the holder previously has given to the trustee written notice of default
       and the default continues;

     - the holders of at least 25 percent in principal amount of the notes then
       outstanding have both (1) requested the trustee to institute such action
       and (2) offered the trustee reasonable indemnity;

     - the trustee has not instituted such action within 60 days of receipt of
       such request; and

     - the trustee has not received direction inconsistent with such written
       request by the holders of a majority in principal amount of the notes
       then outstanding.

     The above four conditions do not apply to actions by holders of the notes
against us for payment of principal or interest on or after the due date
provided. The indenture contains a covenant that we will file annually with the
trustee a certificate of no default or a certificate specifying any default that
exists.

  DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     We can discharge or defease our obligations under the indenture as set
forth below.

     Under terms satisfactory to the trustee, we may discharge certain
obligations to holders of the notes which have not already been delivered to the
trustee for cancellation. These notes must also:

     - have become due and payable; or

     - be due and payable by their terms within one year.

     We may discharge the notes by irrevocably depositing an amount certified to
be sufficient to pay at maturity or upon redemption the principal of and
interest on and any liquidated damages with respect to the notes. We may make
the deposit in cash or U.S. Government Obligations, as defined in the indenture.

     We may also, upon satisfaction of the conditions listed below, discharge
certain obligations to holders of the notes at any time ("Defeasance"). Under
terms satisfactory to the trustee, we may be released from the obligations
imposed by the sections containing the covenants described above limiting liens
and consolidations, mergers and conveyances of assets. Also under terms
satisfactory to the trustee, we may omit to comply with these sections without
creating an event of default ("Covenant Defeasance"). Defeasance or Covenant
Defeasance may be effected only if, among other things:

     - we irrevocably deposit with the trustee cash or U.S. Government
       Obligations as trust funds in an amount certified to be sufficient to pay
       at maturity or upon redemption the principal of and interest on all
       outstanding notes; and

     - we deliver to the trustee an opinion of counsel to the effect that the
       holders of the notes will not recognize income, gain or loss for United
       States federal income tax purposes as a result of such Defeasance or
       Covenant Defeasance. The opinion must further state that these holders
       will be subject to United States federal income tax on the same amounts,
       in the same manner and at the same times as would have been the case if
       Defeasance or Covenant Defeasance had not occurred. In the case of a
       Defeasance, this opinion must be based on a ruling of the Internal
       Revenue

                                        25


       Service or a change in United States federal income tax law occurring
       after the date of the indenture, since this result would not occur under
       current tax law.

  CONCERNING THE TRUSTEE

     The trustee is one of a number of banks with which we and our subsidiaries
maintain ordinary banking relationships and with which we and our subsidiaries
maintain credit facilities.

  GOVERNING LAW

     The indenture and the notes are governed by, and construed in accordance
with, the laws of the State of New York.

                                        26


                      EXCHANGE OFFER; REGISTRATION RIGHTS

     We entered into a registration rights agreement with Salomon Smith Barney
Inc. and other institutions, as the initial purchasers of the old notes, for
your benefit. In the registration rights agreement, we agreed to:

     - file with the SEC within 75 days after the initial issuance of the old
       notes a registration statement relating to an offer to exchange the old
       notes for registered new notes with principal amount and terms identical
       in all material respects to the principal amount and terms of the old
       notes, except that the registered notes would not contain terms with
       respect to transfer restrictions under the Securities Act or the payment
       of liquidated damages;

     - use our reasonable best efforts to cause the exchange offer registration
       statement to be declared effective under the Securities Act within 120
       days after the initial issuance of the old notes;

     - commence the exchange offer promptly after the exchange offer
       registration statement has been declared effective;

     - use our reasonable best efforts to keep the exchange offer registration
       statement effective until the closing of the exchange offer; and

     - use our reasonable best efforts to cause the exchange to be completed
       within 60 days after the SEC declares the exchange offer registration
       statement effective.

     Promptly after the exchange offer registration statement has been declared
effective, we will offer the new notes in exchange for surrender of the old
notes. We will keep the exchange offer open for at least 20 business days, or
longer if required by applicable law, after the effective date of the
registration statement. Interest will accrue on each new note from the last
interest payment date on which we paid interest on the old note tendered in the
exchange offer, or if we have not paid interest on the tendered old note, from
the date of original issuance of the old note.

     Based on existing interpretations of the Securities Act by the staff of the
SEC set forth in several no-action letters to third parties, we believe that you
may offer for resale, resell and otherwise transfer the new notes without
further compliance with the registration and prospectus delivery requirements of
the Securities Act. However, if you are an affiliate of ours, if you intend to
participate in the exchange offer for the purpose of distributing the new notes
or if you are a broker-dealer who purchased the old notes for the purpose of
reselling the notes under Rule 144A or any other available exemption under the
Securities Act, you:

     - will not be able to rely on the interpretation of the staff of the SEC
       set forth in these letters;

     - will not be entitled to tender your old notes in the exchange offer; and

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any resale or transfer of the old
       notes unless the resale or transfer is made under an exemption from those
       requirements.

     If you wish to exchange your old notes for new notes in the exchange offer,
you will be required to represent that:

     - you are not an affiliate of ours;

     - at the time of the exchange offer, you have no arrangement or
       understanding with any person to participate in the distribution, within
       the meaning of the Securities Act, of the new notes; and

     - you are acquiring the new notes in the ordinary course of your business.

     In addition, any broker-dealer who acquired the old notes for its own
account as a result of market-making or other trading activities must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of the new notes. The SEC has taken the position that broker-dealers may
use the prospectus contained in the registration statement to fulfill this
prospectus delivery requirement.
                                        27


Under the registration rights agreement, we must allow broker-dealers and any
other persons subject to prospectus delivery requirements to use the prospectus
contained in the registration statement in connection with the resale of the new
notes.

     If (1) we determine that applicable law or the applicable interpretations
of the staff of the SEC do not permit us to effect the exchange offer, (2) for
any other reason the exchange offer has not been consummated within 180 days
after the initial issuance of the old notes or (3) in the written opinion of
counsel for holders of the old notes, a shelf registration statement must be
filed and a prospectus must be delivered by a holder of the old notes in
connection with its reoffering or resale of the old notes, then in addition to,
or instead of, effecting the registration of the new notes under the exchange
offer registration statement, we will:

     - file a shelf registration statement covering resales of the old notes
       within 75 days after the determination described in clause (1), the last
       date described in clause (2) or our receipt of the opinion described in
       clause (3), as applicable;

     - use our reasonable best efforts to cause the shelf registration statement
       to be declared effective under the Securities Act within 60 days after
       filing the registration statement; and

     - use our reasonable best efforts to keep the shelf registration statement
       continuously effective until the earlier of (1) the expiration of the
       period referred to in Rule 144(k) under the Securities Act, or similar
       successor rule, with respect to the notes or (2) such time as all of the
       old notes have been sold under the shelf registration statement or
       otherwise cease to be registrable notes within the meaning of the
       registration rights agreement.

     If we file a shelf registration statement, we will notify you when the
shelf registration statement has become effective and take other actions which
are required to permit unrestricted resales of the old notes. If you sell old
notes under the shelf registration statement, you will be:

     - required to deliver information to be used in connection with the shelf
       registration statement;

     - required to be named as a selling security holder in the related
       prospectus;

     - required to deliver a prospectus to purchasers;

     - subject to certain of the civil liability provisions under the Securities
       Act in connection with the sales; and

     - bound by some of the provisions of the registration rights agreement,
       including those regarding indemnification rights and obligations.

     By accepting an old note, you will be deemed to have agreed to be bound by
the provisions of the registration rights agreement. Under the registration
rights agreement, upon receipt of notice from us of the occurrence of any event
which makes any statement of a material fact in the prospectus which is part of
the exchange registration statement or shelf registration statement untrue or
which requires the making of any changes in the prospectus in order to make the
statements in the prospectus not misleading, you must suspend the disposition of
the old notes until we have amended or supplemented the prospectus to correct
the misstatement or omission and have furnished copies of the amended or
supplemented prospectus to you.

     For purposes of the registration rights agreement, "transfer restricted
securities" means each note until the earliest on the date of which (i) the note
is exchanged in the exchange offer and entitled to be resold to the public by
the holder of the note without complying with the prospectus delivery
requirements of the Securities Act, (ii) the note has been disposed of in
accordance with the shelf registration statement, (iii) the note is disposed of
by a broker-dealer pursuant to the "Plan of Distribution" contemplated by the
exchange offer registration statement (including delivery of the prospectus
contained therein) or (iv) the note is distributed to the public pursuant to
Rule 144 or under the Securities Act.

                                        28


     If:

     - we do not file with the SEC an exchange offer registration statement
       which we are required to file under the registration rights agreement on
       or prior to September 16, 2002;

     - the SEC does not declare an exchange offer registration statement
       effective on or prior to October 30, 2002;

     - we do not file with the SEC a shelf registration statement which we are
       required to file under the registration rights agreement on or prior to
       the date specified in the registration rights agreement and described
       above;

     - we do not consummate the exchange offer by December 30, 2002; or

     - we have filed, and the SEC has declared effective, the shelf registration
       statement and at any time prior to the expiration of the period referred
       to in Rule 144(k) under the Securities Act, or similar successor rule,
       with respect to the old notes, other than after all the old notes have
       been disposed of under the shelf registration statement or cease to be
       registrable notes under the registration rights agreement, the shelf
       registration statement ceases to be effective, or fails to be usable for
       its intended purpose without being succeeded within two business days by
       a post-effective amendment which cures the failure and that is itself
       immediately declared effective;

(each, a "Registration Default") then we agree to pay each holder of transfer
restricted securities affected thereby liquidated damages in an amount equal to
0.25% per annum of the principal amount of transfer restricted securities held
by such holder for the first 90 day period immediately following the occurrence
of a Registration Default, increasing to 0.50% per annum thereafter, from and
including the date on which any such Registration Default occurs. We shall not
be required to pay liquidated damages for more than one Registration Default at
any given time. Following the cure of all Registration Defaults, the accrual of
liquidated damages will cease.

     We did not file this registration statement on or prior to September 16,
2002, nor was it declared effective on or prior to October 31, 2002. Therefore,
liquidated damages have been accruing since September 17, 2002. The liquidated
damages will cease to accrue as of the date of this prospectus. However, since
the exchange offer will not be consummated by December 30, 2002, liquidated
damages will begin to accrue from December 31, 2002 until such time as the
exchange offer is consummated.

     We have agreed to (1) pay all expenses incident to the exchange offer and
(2) indemnify the initial purchasers and holders of the notes against some
liabilities, including liabilities under the Securities Act.

     We have not completely summarized the provisions of the registration rights
agreement in this prospectus and our summary is subject to, and is qualified in
its entirety by reference to, the actual registration rights agreement. For a
complete description of the terms of the registration rights agreement, you
should read the registration rights agreement, which is filed as an exhibit to
the registration statement of which this prospectus is a part. In addition, you
should not construe our description of the interpretations of, and positions
taken by, the staff of the SEC as legal advice. You should consult your own
legal advisor about this matter.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a discussion of the material U.S. federal income and
estate tax consequences applicable to the exchange of old notes for new notes in
the exchange offer and the ownership and disposition of the notes by an initial
beneficial owner of the notes that is a "non-U.S. holder," as defined below.
This discussion is based upon current provisions of the Internal Revenue Code of
1986, as amended, its legislative history, final, temporary and proposed
regulations, published rulings, and court decisions, all of which are subject to
change, possibly on a retroactive basis. For purposes of this discussion, you
are a "U.S. holder" if you are a beneficial owner of notes who is a "United
States person"

                                        29


for United States federal income tax purposes or a "non-U.S. holder" if you are
a beneficial owner of notes and are not a U.S. holder. A "United States person"
is:

     - a citizen or resident of the United States,

     - a corporation, partnership, or other entity created or organized in the
       United States or under the law of the United States or of any state
       thereof including the District of Columbia,

     - an estate whose income is subject to United States federal income
       taxation regardless of its source, or

     - a trust if a U.S. court is able to exercise primary supervision over the
       administration of the trust and one or more United States persons have
       the authority to control all substantial decisions of the trust.

     This discussion only applies to you if you are a beneficial owner of the
notes who holds the notes as capital assets. The tax treatment of holders of the
notes may vary depending upon their particular situations. Particular persons
including, for example, insurance companies, tax exempt organizations, financial
institutions, partnerships or other entities classified as partnerships for U.S.
federal income tax purposes, and broker-dealers, may be subject to special rules
not discussed below. If a partnership holds notes, the tax treatment of a
partner generally will depend on the status of the partner and the activities of
the partnership. Prospective investors are urged to consult their own tax
advisors regarding the particular U.S. federal tax consequences of holding and
disposing of notes, as well as any tax consequences that may arise under the
laws of any relevant foreign, state, local, or other taxing jurisdiction or
under any applicable tax treaty.

TAX CONSEQUENCES OF THE EXCHANGE OFFER

     The exchange of old notes for new notes pursuant to the exchange offer will
not be a taxable event for U.S. federal income tax purposes. U.S. holders and
non-U.S. holders will not recognize any taxable gain or loss as a result of the
exchange and will have the same tax basis and holding period in the new notes as
they had in the old notes immediately before the exchange.

TAX CONSEQUENCES TO NON-U.S. HOLDERS

  Payment of Interest

     Generally, interest we pay to you will not be subject to U.S. federal
income tax, provided that this interest income is not effectively connected with
your conduct of a United States trade or business, and will not be subject to
United States federal withholding tax provided that:

     - you do not actually or constructively own 10% or more our of the combined
       voting power of all classes of our stock,

     - you are not, for U.S. federal income tax purposes, a controlled foreign
       corporation related to us within the meaning of the Internal Revenue
       Code,

     - you are not a bank receiving interest on a loan entered into in the
       ordinary course of its business within the meaning of the Internal
       Revenue Code, and

     - either (A) you provide a Form W-8BEN (or a suitable substitute form),
       signed under penalties of perjury that includes your name and address and
       certify as to your non-U.S. holder status in compliance with applicable
       law and regulations or (B) hold your notes through a securities clearing
       organization, bank or other financial institution that holds customers'
       securities in the ordinary course of its trade or business and that
       provides a statement signed under penalties of perjury in which it
       certifies to us or our agent that a Form W-8BEN (or suitable substitute),
       has been received by it from you or a qualifying intermediary and
       furnishes us or our agent with a copy thereof.

                                        30


     If these conditions are not satisfied, then interest paid on the notes will
be subject to U.S. federal withholding tax at a rate of 30% unless that rate is
reduced or eliminated pursuant to an applicable tax treaty and you provide a
properly completed and executed IRS Form W-8BEN.

  Sale, Exchange or Redemption of the Notes

     You generally will not be subject to U.S. federal income and withholding
tax on any gain realized on the sale, exchange, redemption or other disposition
of a note unless:

     - the gain is effectively connected with your conduct of a United States
       trade or business, or, under an applicable tax treaty, is attributable to
       a permanent establishment you maintain in the United States, or

     - if you are an individual, you are present in the United States for a
       period or periods aggregating 183 days or more during the taxable year of
       the disposition and certain other requirements are met.

  Effectively Connected Income

     If the interest, gain or other income you recognize on a note is
effectively connected with your conduct of a trade or business within the United
States, you will be exempt from the withholding tax previously discussed if an
appropriate statement is furnished, but generally will be subject to U.S.
federal income tax on the interest, gain or other income at regular federal
income tax rates. In addition to regular U.S. federal income tax, if you are a
corporation, you may be subject to a branch profits tax equal to 30% of your
effectively connected earnings and profits, as adjusted for certain items,
unless you qualify for a lower rate under an applicable tax treaty.

  U.S. Federal Estate Tax Considerations

     A note beneficially owned by an individual who is not a citizen or resident
of the United States at the time of death will generally not be includable in
the decedent's gross estate for U.S. federal estate tax purposes, provided that
the beneficial owner did not at the time of death actually or constructively own
10% or more of the combined voting power of all classes of our stock entitled to
vote, and provided that, at the time of the holder's death, payments with
respect to that note would not have been effectively connected with the holder's
conduct of a trade or business within the United States.

  Information Reporting and Backup Withholding Tax

     United States information reporting requirements and backup withholding tax
generally will not apply to payments of interest and principal on a note if you
provide the certification described in "Payment of Interest" or otherwise
establish an exemption, provided that we do not have actual knowledge or reason
to know that you are a United States person.

     Information reporting requirements and backup withholding tax generally
will not apply to any payment of the proceeds of the sale of a note effected
outside the United States by a foreign office of a "broker." However, if the
broker:

     - is a United States person,

     - derives 50% or more of its gross income from all sources for certain
       periods from the conduct of a United States trade or business,

     - is a controlled foreign corporation for United States tax purposes or

     - is a foreign partnership in which one or more United States persons, in
       the aggregate, own more than 50% of the income or capital interests in
       the partnership or a foreign partnership that is engaged in a trade or
       business in the United States,

                                        31


payment of the proceeds will be subject to information reporting requirements
unless the broker has documentary evidence in its records that you are a
non-U.S. holder and certain other conditions are met, or you otherwise establish
an exemption.

     Payment of the proceeds of any sale of a note to or through the United
States office of a broker, whether foreign or United States, is subject to
information reporting and backup withholding requirements, unless you provide
the certification described in "Payment of Interest" or otherwise establish an
exemption and the broker does not have actual knowledge or reason to know that
you are a United States person or that the exemption conditions are not
satisfied.

     Backup withholding is not an additional tax. Any amounts withheld from a
payment to you under the backup withholding rules will be allowed as a credit
against your U.S. federal income tax liability and may entitle you to a refund,
provided that the required information is provided to the IRS.

     THIS DISCUSSION IS INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE
APPLICABLE DEPENDING UPON YOUR PARTICULAR SITUATION. YOU SHOULD CONSULT YOUR TAX
ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO YOU OF THE OWNERSHIP AND
DISPOSITION OF THE NOTES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR
OTHER TAX LAWS.

                          CERTAIN ERISA CONSIDERATIONS

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

GENERAL FIDUCIARY MATTERS

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

     In considering an investment in the notes of a portion of the assets of any
Plan, a fiduciary should determine whether the investment is in accordance with
the documents and instruments governing the Plan and the applicable provisions
of ERISA, the Code or any similar law relating to a fiduciary's duties to the
Plan including, without limitation, the prudence, diversification, delegation of
control and prohibited transaction provisions of ERISA, the Code and any other
applicable Similar Laws

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

PROHIBITED TRANSACTION ISSUES

     Section 406 of ERISA and Section 4975 of the Code prohibit Plans subject to
Title I of ERISA or Section 4975 of the Code from engaging in specified
transactions involving plan assets with persons or entities who are "parties in
interest," within the meaning of ERISA, or "disqualified persons," within the

                                        32


meaning of Section 4975 of the Code, unless an exemption is available. A party
in interest or disqualified person who engaged in a non-exempt prohibited
transaction may be subject to excise taxes and other penalties and liabilities
under ERISA and the Code. In addition, the fiduciary of the Plan that engaged in
such a non-exempt prohibited transaction may be subject to penalties and
liabilities under ERISA and the Code. The acquisition and/or holding of notes by
a Plan with respect to which we, our affiliates or the Initial Purchaser is
considered a party in interest or a disqualified person may constitute or result
in a direct or indirect prohibited transaction under ERISA and/or the Code,
unless the investment is acquired and is held in accordance with an applicable
statutory, class or individual prohibited transaction exemption. In this regard,
the U.S. Department of Labor has issued prohibited transaction class exemptions,
or "PTCEs," that may apply to the acquisition and holding of the notes. These
class exemptions include PTCE 84-14 respecting transactions determined by
independent qualified professional asset managers, PTCE 90-1 respecting
insurance company pooled separate accounts, PTCE 91-38 respecting bank
collective investment trusts, PTCE 95-60 respecting life insurance company
general accounts and PTCE 96-23 respecting transactions determined by in-house
asset managers. However, there can be no assurance that all of the conditions of
any such exemptions will be satisfied, or, if satisfied, that the scope of the
relief will cover all acts which might be construed as prohibited transactions.

     Because of the foregoing, the notes should not be purchased or held by any
person investing "plan assets" of any Plan, unless such purchase and holding
will not constitute a non-exempt prohibited transaction under ERISA and the Code
or similar violation of any applicable Similar Laws whether pursuant to an
applicable exemption or otherwise.

     The foregoing discussion is general in nature and is not intended to be all
inclusive. Due to the complexity of these rules and the penalties that may be
imposed upon persons involved in non-exempt prohibited transactions, it is
particularly important that fiduciaries, or other persons considering purchasing
the notes on behalf of, or with the assets of, any Plan, consult with their
counsel regarding the potential applicability of ERISA, Section 4975 of the Code
and any similar laws to such investment and whether an exemption would be
applicable to the purchase and holding of the notes.

                                        33


                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives new notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the new notes. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of new notes received in exchange for old notes where the old notes
were acquired as a result of market-making activities or other trading
activities. We have agreed that for 180 days after the closing of the exchange
offer we will make this prospectus, as amended or supplemented, available to any
broker-dealer that requests these documents from the Exchange Agent for use in
connection with resales of the new notes. In addition, until           , 2003,
all dealers effecting transactions in the new notes may be required to deliver a
prospectus.

     We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account in
the exchange offer may be sold from time to time in one or more transactions in
the over-the-counter market, in negotiated transactions, through the writing of
options on the new notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any resale of the new notes may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such new notes. Any broker-dealer
that resells new notes that were received by it for its own account in the
exchange offer and any broker or dealer that participates in a distribution of
the new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act. Any profit on any resale of new notes and any commissions or
concessions received by any persons deemed to be underwriters may be deemed to
be underwriting compensation under the Securities Act. The enclosed letter of
transmittal states that by acknowledging that it will deliver and be delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the closing of the exchange offer, we will
promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all expenses incident to the
exchange offer (including the expenses of one counsel for the holders of the old
notes) other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the old notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

     Following completion of the exchange offer, we may, in our sole discretion,
commence one or more additional exchange offers to holders of old notes who did
not exchange their old notes for new notes in the exchange offer on terms which
may differ from those contained in the prospectus and the enclosed letter of
transmittal. This prospectus, as it may be amended or supplemented from time to
time, may be used by us in connection with any additional exchange offers. These
additional exchange offers may take place from time to time until all
outstanding old notes have been exchanged for new notes, subject to the terms
and conditions in the prospectus and letter of transmittal distributed by us in
connection with these additional exchange offers.

                                 LEGAL MATTERS

     The validity of the new notes will be passed upon for us by Andrews & Kurth

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Transcontinental Gas Pipe Line Corporation is empowered by Section 145 of
the General Corporation Law of Delaware, subject to the procedures and
limitations stated therein, to indemnify any person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with any threatened, pending or
completed action, suit or proceeding in which such person is made a party by
reason of such person being or having been a director, officer, employee or
agent of Transcontinental Gas Pipe Line Corporation. The statute provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under any by-law, agreement,
vote of stockholders or disinterested directors, or otherwise. The By-laws of
Transcontinental Gas Pipe Line Corporation provide for indemnification by it of
its directors and officers to the fullest extent permitted by the General
Corporation Law of Delaware. In addition, Transcontinental Gas Pipe Line
Corporation has entered into indemnity agreements with its directors and certain
officers providing for, among other things, the indemnification of and the
advancing of expenses to such individuals to the fullest extent permitted by
law, and, to the extent insurance is maintained, for the continued coverage of
such individuals.

     Policies of insurance are maintained by Transcontinental Gas Pipe Line
Corporation under which its directors and officers are insured, within the
limits and subject to the limitations of the policies, against certain expenses
in connection with the defense of actions, suits or proceedings, and certain
liabilities which might be imposed as a result of such actions, suits or
proceedings, to which they are parties by reason of being or having been such
directors or officers.

ITEM 22.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

          (a)(1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment theory thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered)and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes
        in volume and price represent no more than a 20% change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement; and

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed with or furnished
     to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the
     Securities Exchange Act of 1934 that are incorporated by reference in the
     registration statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

          (b) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
     (and, where applicable, each filing of an employee benefit plan's annual
     report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
     that is incorporated by reference in the registration statement shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (c) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this
     form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

          (d) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the Registration Statement when
     it became effective.

          (e) To file an application for the purpose of determining the
     eligibility of the trustee to act under subsection (a) of section 310 of
     the Trust Indenture Act ("Act") in accordance with the rules and
     regulations prescribed by the Commission under Section 305(b)2 of the Act.

                                       II-2
