                                    SUMMARY

     This summary highlights information appearing in other sections of this
prospectus supplement and the accompanying prospectus. It may not contain all of
the information that you should consider before investing in the notes. You
should read the prospectus supplement and the accompanying prospectus carefully,
including the "Risk Factors" section and the financial statements and the
footnotes to those statements incorporated herein by reference. For purposes of
this prospectus supplement and the accompanying prospectus, unless the context
otherwise indicates, when we refer to "us," "we," "our," "ours," or "El Paso,"
we are describing El Paso Corporation and its subsidiaries.

                                  OUR BUSINESS

     We are a global energy company with operations that span the wholesale
energy value chain, from energy production and extraction to power generation.

     Our principal operations include:

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

     - marketing of energy and energy-related commodities and products;

     - generation of power;

     - refining of petroleum;

     - production of chemicals;

     - development and operation of energy infrastructure facilities;

     - exploration and production of natural gas and oil; and

     - mining of coal.

     Our Pipelines segment owns or has interests in approximately 60,000 miles
of interstate natural gas pipelines in the U.S. and internationally. In the
U.S., our systems connect the nation's principal natural gas supply regions to
the five largest consuming regions in the United States: the Gulf Coast,
California, the Northeast, the Midwest, and the Southeast. These operations
represent one of the largest, and only, integrated coast-to-coast mainline
natural gas transmission system in the U.S. Our U.S. pipeline systems also own
or have interests in over 425 billion cubic feet of storage capacity used to
provide a variety of services to our customers. Our international pipeline
operations include access from our U.S. based systems into Canada and Mexico as
well as interests in three major operating natural gas transmission systems in
Australia.

     Our Merchant Energy segment is involved in a broad range of activities in
the energy marketplace including asset ownership, trading and risk management
and financial services. We are one of North America's largest wholesale energy
commodity marketers and traders, and buy, sell, and trade natural gas, power,
crude oil, refined products, coal, and other energy commodities in the U.S. and
internationally. We are also a significant non-utility owner of electric
generating capacity with 84 facilities in 20 countries. Our four refineries have
the capacity to process 538,000 barrels of crude oil per day and produce a
variety of gasolines and other products. We also produce agricultural and
industrial chemicals and petrochemicals at seven facilities in the U.S. and
Canada. Our coal operations produce high-quality, bituminous coal with reserves
in Kentucky, Virginia, and West Virginia. Most recently, we have announced our
expansion into the liquefied natural gas business, capitalizing upon the U.S.
and worldwide demand for natural gas. The financial services businesses of
Merchant Energy invest in emerging businesses to facilitate growth in the U.S.
and Canadian energy markets. As a global energy merchant, we evaluate and
measure risks inherent in the markets we serve, and use sophisticated systems
and integrated risk management techniques to manage those risks.

     Our Field Services segment provides natural gas gathering, products
extraction, fractionation, dehydration, purification, compression and intrastate
transmission services. These services include gathering

                                       S-1
   4

of natural gas from more than 15,000 natural gas wells with approximately 24,000
miles of natural gas gathering and natural gas liquids pipelines, and 35 natural
gas processing, treating, and fractionation facilities located in some of the
most prolific and active production areas in the U.S., including the San Juan
Basin, east and south Texas, Louisiana, the Gulf of Mexico, and the Rocky
Mountains. We conduct our intrastate transmission operations through interests
in six intrastate systems, which serve a majority of the metropolitan areas and
industrial load centers in Texas as well as markets in Louisiana. Our primary
vehicle for growth and development of midstream energy assets is El Paso Energy
Partners, L.P., a publicly traded master limited partnership of which our
subsidiary is the general partner. Through Energy Partners, we provide natural
gas and oil gathering and transportation, storage, and other related services,
principally in the Gulf of Mexico.

     Our Production segment leases approximately 5 million net acres in 16
states, including Colorado, Kansas, Louisiana, New Mexico, Texas, Oklahoma,
Utah, Wyoming, and Arkansas, as well as the Gulf of Mexico. We also have
exploration and production rights in Australia, Brazil, Canada, Hungary,
Indonesia, and Turkey. During 2000, daily equivalent natural gas production
exceeded 1.6 billion cubic feet per day, and our reserves at December 31, 2000,
were approximately 6.4 trillion cubic feet of natural gas equivalents.

     In addition to our energy activities, we have announced a
telecommunications strategy that will leverage our knowledge of the commodity
and capital markets into the emerging telecommunications market. Our strategy
involves:

     - accessing fiber deep within metropolitan markets to aggregate supply in
       major U.S. cities;

     - utilizing fiber rings and key points of interconnection of major carriers
       and service providers to allow for liquidity to develop in major markets;
       and

     - assembling a high capacity thin fiber national long-haul backbone.

     We will overlay against this asset base a merchant-based operating support
system and valuation models that will allow us to apply the merchant skills
developed in our core commodity business to the rapidly changing
telecommunications markets.

     Our principal executive offices are located in the El Paso Building,
located at 1001 Louisiana Street, Houston, Texas 77002, and our telephone number
at that address is (713) 420-2600.

                              RECENT DEVELOPMENTS

FIRST QUARTER RESULTS

     For the first quarter ended March 31, 2001, we had a net loss of $400
million versus net income of $428 million for the quarter ended March 31, 2000.
The 2001 loss was a result of merger-related costs and asset impairment charges
totaling $1,161 million, or $890 million after taxes, related to our merger with
Coastal. In addition, we recorded net extraordinary losses totaling $10 million
aftertax as a result of Federal Trade Commission (FTC) ordered sales of our
Gulfstream project and, our investments in the Empire pipeline and Stingray
pipeline systems. During the first quarter of 2000, merger-related charges were
$4 million, or $3 million aftertax, and we recorded aftertax gains on FTC
ordered sales of our East Tennessee and Sea Robin Pipeline systems totaling $89
million. Net income, excluding the aftertax effects of merger-related charges
and extraordinary items, was $500 million in 2001, versus an adjusted $342
million, or 46 percent higher in 2001 versus 2000.

     Earnings before interest and taxes, or EBIT, was a loss of $68 million in
2001 versus earnings of $765 million in 2000. Excluding merger-related charges,
comparative EBIT was $1,093 million in 2001 versus $769 million in 2000, or an
increase of 42 percent. EBIT from the non-regulated segment of our business,
which includes our Merchant Energy, Production and Field Services segments,
totaled 63 percent of all operating segments, with our pipeline segment
contributing 37 percent of the total.

(2)  We restated historical operating revenues due to the implementation in 2000
     of Emerging Issues Task Force Issue No. 99-19, Reporting Revenue Gross as a
     Principal versus Net as an Agent, which provides guidance on the gross

                        SUMMARY COMBINED FINANCIAL DATA

     On January 29, 2001, we completed our merger with Coastal. The information
below presents the operating results data and financial position data from our
audited combined financial statements for the year ended December 31, 2000. Our
merger was accounted for as a pooling of interests. We filed on March 23, 2001 a
Current Report on Form 8-K reflecting supplemental combined financial data which
includes The Coastal Corporation operations for all periods presented. You
should read the following information together with our historical financial
statements and related notes contained in our 2000 Annual Report on Form 10-K,
as well as with the supplemental combined financial data and related notes
included in the Current Report on Form 8-K.

(1) Our operating results and financial position reflect the acquisitions in
    August 1998 of DeepTech International, and in December 2000 of PG&E's Texas
    Midstream operations. These acquisitions were accounted for as purchases and
    therefore operating results are included in our results prospectively from
    the purchase date.

(2) We restated historical operating revenues due to the implementation in 2000
    of Emerging Issues Task Force Issue No. 99-19, Reporting Revenue Gross as a
    Principal versus Net as an Agent, which provides guidance on the gross
    versus net presentation of revenues and expenses and to adjust Coastal's
    presentation of its petroleum trading activities to our manner of
    presentation. These reclassifications impacted operating revenues and
    expenses, but had no impact on net income or earnings per share.

(3) Reflects the consolidation of the U.S. operations of Coastal Merchant Energy
    in September 2000 as well as the significant growth in our Merchant Energy
    operations in 2000.

(4) Ceiling test charges are reductions in earnings that result when capitalized
    costs of natural gas and oil properties exceed the upper limit, or ceiling,
    on the value of these properties.

(5) We have assumed that cash dividends declared per share of common stock are
    the same as the historical dividends declared by El Paso during the periods
    presented.

                                  RISK FACTORS

     Before you invest in the notes, you should read the risks, uncertainties
and factors which may adversely affect us that are discussed under the caption
"Risk Factors and Cautionary Statement For Purposes of the "Safe Harbor"
Provisions of the Private Securities Litigation Reform Act of 1995" in our
Current Report on Form 8-K, filed March 23, 2001, which is incorporated by
reference in this prospectus supplement, as well as the following additional
risk factor related to this offering.

WE ARE A HOLDING COMPANY THAT DEPENDS ON CASH FLOW FROM OUR SUBSIDIARIES TO MEET
OUR DEBT SERVICE OBLIGATIONS.

     As a holding company, we conduct all of our operations exclusively through
our subsidiaries and our only significant assets are our investment in these
subsidiaries. This means that we are dependent on dividends or other
distributions of funds from our subsidiaries to meet our debt service and other
obligations, including the payment of principal and interest on the notes. Our
subsidiaries are separate and distinct legal entities and have no obligation to
pay any amounts due on these notes or to provide us with funds for our payment
obligations, whether by dividends, distributions, loans or other payments. In
addition, any payment of dividends, distributions, loans or advances by our
subsidiaries to us could be subject to statutory or contractual restrictions.
Payments to us by our subsidiaries will also be contingent upon our
subsidiaries' earnings and business considerations.

     The indenture governing the notes, subject to certain restrictions, permits
us to incur additional secured indebtedness and permits our subsidiaries to
incur additional secured and unsecured indebtedness, which would in effect be
senior to the notes. The indenture also permits certain of our subsidiaries to
pledge assets in order to secure our indebtedness and to agree with lenders
under any secured indebtedness to restrictions on repurchase of the notes and on
the ability of those subsidiaries to make distributions, loans, other payments
or asset transfers to us. The total long-term indebtedness of our subsidiaries
as of December 31, 2000, was approximately $3.4 billion and was approximately
$8.8 billion on a pro forma combined basis giving effect to our merger with
Coastal.

(1)  Gives effect to our merger with Coastal (accounted for as a pooling of
     interests) as if it occurred on December 31, 2000.

(2)  Since December 31, 2000, the following events have occurred to impact the
     total capitalization presented above:

     In February 2001, one of our wholly owned subsidiaries, Southern Natural
     Gas Company, issued $300 million of long-term debt. Southern used
     approximately $100 million to repay long-term debt, and the remainder was
     used for general corporate purposes.

     In February 2001, we issued $1,766,500,000 aggregate principal amount at
     maturity of Zero Coupon Convertible Debentures due February 28, 2021. We
     used the proceeds from that offering, approximately $784 million, to repay
     short term borrowings and for general corporate purposes.

     In March 2001, we issued E550 million (approximately $510 million) of euro
     notes at 5.75% due 2006. Proceeds of approximately $505 million, net of
     issuance costs, were used to repay short-term debt and for general
     corporate purposes. To reduce our exposure to foreign currency risk, we
     entered into a swap transaction exchanging the euro note for a $510 million
     U.S. dollar denominated obligation with a fixed interest rate of 6.61% for
     the five year term of the note.

     In the first quarter of 2001, we adopted Financial Accounting Standards
     Board Statement of Financial Accounting Standards No. 133, Accounting for
     Derivate Instruments and Hedging Activities (SFAS No. 133). Based on
     commodity prices, interest rates, and foreign currency exchange rates
     existing at December 31, 2000, we will reflect the impact of our adoption
     of SFAS No. 133 as of January 1, 2001, by recording a cumulative effect
     transition adjustment as a charge to other comprehensive income of $1,280
     million, net of income taxes. This charge to other comprehensive income
     represents the fair value of our derivative instruments designated as cash
     flow hedges. The majority of the initial charge relates to the hedging of
     the forecasted sales of natural gas we expect to produce through the end of
     2001.

(3)  Adjusted to reflect the application of the estimated proceeds from the
     issuance of approximately $496 million of the notes in this offering.

(4)  Upon completion of our merger with Coastal, we had 513,815,775 shares
     issued as of December 31, 2000.

                                USE OF PROCEEDS

     We will use the proceeds from the sale of the $500,000,000 of notes issued
in this offering to repay outstanding commercial paper and other short-term
indebtedness (the outstanding balance of which was approximately $1,078 million
as of March 31, 2001 having a weighted average annual interest rate at that date
of 6.21%) and for general corporate purposes. Funds not required immediately for
such purposes may be invested in marketable securities and short-term
interest-bearing investments.

                            DESCRIPTION OF THE NOTES

     The notes are to be issued under an indenture between El Paso and The Chase
Manhattan Bank, as trustee, dated as of May 10, 1999, as amended, copies of
which may be obtained from the trustee at its corporate trust office in New
York, New York. The terms of the notes include those stated in the indenture and
made a part thereof by reference to the Trust Indenture Act in effect on the
date of the indenture. This summary of the terms of the notes and the indenture
is not complete and is subject to, and is qualified in its entirety by reference
to, the indenture, including the definitions of some of the terms in the
indenture, and the Trust Indenture Act. Terms used in this section and not
otherwise defined in this section have the respective meanings assigned to them
in the indenture.

GENERAL

     The notes will be unsecured and will rank senior in right of payment to all
subordinated debt of El Paso. The notes will be limited to an aggregate
principal amount of $500,000,000. The indenture does not limit the incurrence or
issuance of other secured or unsecured debt of El Paso, whether under the
indenture or any existing or other indenture that El Paso may enter into in the
future or otherwise.

     The notes are not subject to any sinking fund provision. The entire
principal amount of the notes will mature, and become due and payable, together
with any accrued and unpaid interest thereon, on May 15, 2011.

     We may redeem the notes as described below, and we may purchase notes in
the open market, by tender or otherwise.

INTEREST

     The notes will bear interest at the annual rate of 7.0% per annum, payable
semi-annually in arrears on May 15 and November 15 of each year, commencing on
November 15, 2001 (each, an "interest payment date"), to the person in whose
name each note is registered at the close of business on the first day (whether
or not a business day) of the month of such interest payment date (the "regular
record date"), subject to certain exceptions. The amount of interest payable for
any period will be computed on the basis of a 360-day year of twelve 30-day
months. In the event that any date on which interest is payable on the notes is
not a business day, then payment of the interest payable on such date will be
made on the next succeeding day that is a business day (and without any interest
or other payment in respect of any such delay), except that if such business day
is in the next succeeding calendar year, then such payment shall be made on the
immediately preceding business day, in each case with the same force and effect
as if made on such interest payment date.

REDEMPTION

     The notes are redeemable, in whole or in part, at our option at any time at
a redemption price equal to the Make-Whole Price. "Make-Whole Price" means an
amount equal to the greater of (1) 100% of the principal amount of the notes
being redeemed, or (2) an amount equal to, as determined by an Independent
Investment Banker, the sum of the present values of the remaining scheduled
payments of principal and interest on the notes being redeemed, discounted to
the date of redemption on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in each
case, accrued and unpaid interest thereon to the date of redemption. Notice of
any redemption will
                                       S-9
   12

be mailed at least 30 days but not more than 60 days before the date of
redemption to each registered holder of the notes to be redeemed. Unless we
default in payment of the redemption price, on and after the date of redemption,
interest will cease to accrue on the notes or portions thereof called for
redemption. The notes do not provide for any sinking fund.

     "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) that is the same as the
Comparable Treasury Price for such redemption date, plus 0.25%.

     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker that (1) has a maturity comparable
to the remaining term of the notes to be redeemed and (2) would be used, at the
time of selection and in accordance with customary financial practice, to price
new issues of corporate debt securities with a maturity comparable to the
remaining term of the notes to be redeemed.

     "Comparable Treasury Price" means, with respect to any redemption date, (A)
the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, (B) if the Trustee obtains fewer than three such Reference Treasury
Dealer Quotations, the average of all such Reference Treasury Dealer Quotations,
or (C) if only one Reference Treasury Dealer Quotation is received, such
Reference Treasury Dealer Quotation.

     "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Trustee after consultation with El Paso.

     "Reference Treasury Dealer" means (A) each of Salomon Smith Barney Inc.,
BNP Paribas Securities Corp., BNY Capital Markets, Inc. and TD Securities (USA)
Inc. (or their respective affiliates which are Primary Treasury Dealers), and
their respective successors; provided, however, that if any of the foregoing
shall cease to be a primary U.S. Government securities dealer in New York City
(a "Primary Treasury Dealer"), we will substitute therefor another Primary
Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by us.

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

     El Paso may purchase notes in the open market, by tender or otherwise.
Notes so purchased may be held, resold or surrendered to the Trustee for
cancellation. If applicable, El Paso will comply with the requirements of Rule
14e-1 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and other securities laws and regulations in connection with any such
purchase. The notes may be defeased in the manner provided in the indenture.

ADDITIONAL NOTES

     We may, without the consent of the holders of the notes, create and issue
additional notes of any series ranking equally with these notes in all respects,
including having the same CUSIP number, so that such additional notes shall be
consolidated and form a single series with these notes and shall have the same
terms as to status, redemption or otherwise as these notes. No additional notes
may be issued if an event of default under the indenture has occurred and is
continuing with respect to the notes.

BOOK-ENTRY SYSTEM

     The notes will be issued in the form of one or more fully registered global
notes, which will be deposited with, or on behalf of, The Depository Trust
Company (DTC) and registered in the name of the nominee of DTC. Except as
described below, a global note may not be transferred except as a whole by

                                       S-10
   13

DTC to another nominee of DTC or to a successor of DTC or a nominee of such
successor. Transfers of a global note will be effected only through records
maintained by DTC and its participants. Beneficial interests in global notes
will be exchanged for notes in definitive form only under limited circumstances
described herein.

     When we issue a global note, DTC will credit, on its book-entry
registration and transfer system, the respective principal amounts of the notes
represented by such global note to the accounts of participants. The accounts to
be credited shall be designated by the agent through which a note was sold, or
by us if such note was sold directly by us. Ownership of beneficial interests in
a global note will be limited to participants or persons that may hold interests
through participants. Ownership of beneficial interests in a global note is
limited to participants that have accounts with DTC or its nominee, or persons
that may hold interests through those participants. In addition, ownership of
beneficial interests by participants in a global note will be evidenced only by,
and the transfer of that ownership interest will be effected only through,
records maintained by DTC or its nominee for a global note. So long as DTC or
its nominee is the registered owner thereof, DTC or its nominee, as the case may
be, will be considered the sole owner or holder of the notes represented by such
global note for all purposes under the indenture. Ownership of beneficial
interests in a global note by persons that hold interests through participants
will be evidenced only by, and the transfer of that ownership interest within
that participant will be effected only through, records maintained by that
participant. DTC has no knowledge of the actual beneficial owners of the notes.
Beneficial owners will not receive written confirmation from DTC of their
purchase, but beneficial owners are expected to receive written confirmations
providing details of the transaction, as well as periodic statements of their
holdings, from the participants through which the beneficial owners entered the
transaction. The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
laws may impair the ability to transfer beneficial interests in a global note.

     We will make payments of principal of, and interest on, notes represented
by a global note registered in the name of or held by DTC or its nominee to DTC
or its nominee, as the case may be, as the registered owner and holder of the
global note representing those notes. DTC has advised us that upon receipt of
any payment of principal of, or interest on, a global note, DTC will immediately
credit accounts of participants on its book-entry registration and transfer
system with payments in amounts proportionate to their respective beneficial
interests in the principal amount of that global note as shown in the records of
DTC. Payments by participants to owners of beneficial interests in a global note
held through those participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the sole
responsibility of those participants, subject to any statutory or regulatory
requirements that may be in effect from time to time.

     Neither we, any trustee nor any of our respective agents, will be
responsible for any aspect of the records of DTC, any nominee or any participant
relating to, or payments made on account of, beneficial interests in a permanent
global debt security or for maintaining, supervising or reviewing any of the
records of DTC, any nominee or any participant relating to such beneficial
interests.

     A global note is exchangeable for definitive notes registered in the name
of, and a transfer of a global note may be registered to, any person other than
DTC or its nominee, only if:

        - DTC notifies us that it is unwilling or unable to continue as
          depositary for that global note or at any time DTC ceases to be
          registered under the Exchange Act;

        - we determine in our discretion that the global note will be
          exchangeable for definitive notes in registered form; or

        - there shall have occurred and be continuing an event of default or an
          event which, with notice or the lapse of time or both, would
          constitute an event of default under the notes.

                                       S-11
   14

     Any global note that is exchangeable pursuant to the preceding sentence
will be exchangeable in whole for definitive notes in registered form, of like
tenor and of an equal aggregate principal amount as the global note, in
denominations specified in the applicable pricing supplement, if other than
$1,000 and integral multiples of $1,000. The definitive notes will be registered
by the registrar in the name or names instructed by DTC. We expect that these
instructions may be based upon directions received by DTC from its participants
with respect to ownership of beneficial interests in the global notes.

     Except as provided above, owners of the beneficial interests in a global
note will not be entitled to receive physical delivery of notes in definitive
form and will not be considered the holders of notes for any purpose under the
indenture. No global note will be exchangeable except for another global note of
like denomination and tenor to be registered in the name of DTC or its nominee.
Accordingly, each person owning a beneficial interest in a global debt security
must rely on the procedures of DTC and, if that person is not a participant, on
the procedures of the participant through which that person owns its interest,
to exercise any rights of a holder under the global note or the indenture.

     We understand that, under existing industry practices, in the event that we
request any action of holders, or an owner of a beneficial interest in a global
note desires to give or take any action that a holder is entitled to give or
take under the notes or the indenture, DTC would authorize the participants
holding the relevant beneficial interests to give or take that action, and those
participants would authorize beneficial owners owning through those participants
to give or take that action or would otherwise act upon the instructions of
beneficial owners owning through them.

     DTC has advised us that DTC is a limited purpose trust company organized
under the laws of the State of New York, a "banking organization" within the
meaning of the New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered under the Exchange Act. DTC was created
to hold securities of its participants and to facilitate the clearance and
settlement of securities transactions among its participants in those securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. DTC's
participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. DTC is owned by a number
of its participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to DTC's book-entry system is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. The rules
applicable to DTC and its participants are on file with the Securities and
Exchange Commission.

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES
                         FOR NON-UNITED STATES HOLDERS

     The following is a general discussion of the material United States federal
income and estate tax consequences of the ownership and disposition of the notes
by a purchaser of the notes that is a "Non-United States Holder." This
discussion is based upon the Internal Revenue Code of 1986, as amended, (Code)
its legislative history, existing and proposed regulations thereunder, published
rulings, and court decisions, all as in effect on the date of this document, and
all of which are subject to change, possibly on a retroactive basis. For
purposes of this discussion, you are a "Non-United States Holder" if you are a
beneficial owner of notes and you are not a "United States person" for United
States federal tax purposes. A "United States person" is:

     - a citizen or resident of the United States or any political subdivision
       thereof,

     - 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
                                       S-12
   15

     - 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 or
       certain electing trusts that were in existence on August 19, 1996, and
       treated as a domestic trust on that date.

     This discussion only applies to you if you are a Non-United States Holder
who holds the notes as capital assets. The tax treatment of holders of the notes
may vary depending upon their particular situations. Certain holders, including
insurance companies, tax exempt organizations, financial institutions,
broker-dealers and persons holding the notes as part of a "straddle," "hedge" or
"conversion transaction," may be subject to special rules not discussed below.
Prospective investors are urged to consult their own tax advisors regarding the
particular United States 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.

INTEREST

     Interest that we pay to you will not be subject to U.S. federal income tax
and withholding of U.S. federal income tax will not be required on that payment
if you:

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

     - are not a controlled foreign corporation with respect to which we are a
       related person, and

     - you certify to us, our payment agent, or the person who would otherwise
       be required to withhold United States tax, on Form W-8BEN (or applicable
       substitute form), under penalties of perjury, that you are not a United
       States person and provide your name and address.

     If you do not satisfy the three preceding requirements, your interest on a
note would generally be subject to United States withholding tax at a flat rate
of 30% (or a lower applicable treaty rate).

     If you are engaged in trade or business in the United States, and if
interest on a note is effectively connected with the conduct of that trade or
business (or in the case of an applicable tax treaty, is attributable to a
permanent establishment maintained by you in the United States), you will be
exempt from United States withholding tax but will be subject to regular United
States federal income tax on the interest in the same manner as if you were a
United States person. In order to establish an exemption from United States
withholding tax, you must provide to us, our payment agent or the person who
would otherwise be required to withhold United States tax, a properly executed
IRS Form W-8ECI (or applicable substitute form). Under the regulations discussed
below, you may also need to provide a United States taxpayer identification
number (social security number or employer identification number) on that form
in order to meet the requirements for that exemption. In addition to regular
United States federal income tax, if you are a foreign corporation, you may be
subject to a United States branch profits tax.

GAIN ON DISPOSITION

     You generally will not be subject to United States federal income tax with
respect to gain recognized on a sale, redemption, or other disposition of a note
unless:

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

     - if you are an individual, you are present in the United States for 183 or
       more days in the taxable year and certain other requirements are met.

                                       S-13
   16

FEDERAL ESTATE TAXES

     If interest on the notes is exempt from withholding of United States
federal income tax under the rules described above, the notes held by an
individual who at the time of death is a Non-United States Holder generally will
not be subject to United States federal estate tax as a result of such
individual's death provided such individual 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 death,
payments with respect to such note would not have been effectively connected
with the conduct by such individual of a trade or business within the United
States.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     We will, when required, report to you and the Internal Revenue Service the
amount of any interest paid on the notes in each calendar year and the amounts
of tax withheld, if any, with respect to such payments.

     Backup withholding tax is a withholding tax imposed at the rate of 31% on
certain payments to persons who fail to furnish the information required under
United States information reporting requirements. In the case of payments of
interest to you, backup withholding tax and certain information reporting will
not apply to such payments with respect to which either the certification
described under "Interest" above has been received or an exemption has otherwise
been established, provided that neither we nor our payment agent has actual
knowledge that you are a United States person or that the conditions of any
other exemption are not in fact satisfied.

     Payments to you of the proceeds from the sale of a note made to or through
a foreign office of a broker generally will not be subject to information
reporting or backup withholding. However, if the broker is a United States
person, a controlled foreign corporation for United States tax purposes, or a
foreign person 50% or more of whose gross income is effectively connected with a
United States trade or business for a specified three-year period, information
reporting (but not backup withholding) may apply to such payments, unless the
broker has documentary evidence in its records that you are not a United States
person and certain other conditions are met or you otherwise establish an
exemption.

     Payments to you of the proceeds from the sale of a note made to or through
the U.S. office of a broker are subject to information reporting and backup
withholding unless you certify under penalties of perjury as to your non-U.S.
status or otherwise establish an exemption from information reporting and backup
withholding.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be refunded or credited against your United States
federal income tax liability, provided that the required information is
furnished to the Internal Revenue Service.

     The United States Treasury Department has issued new regulations regarding
the withholding and information reporting rules discussed above. In general, the
new regulations do not significantly alter the substantive withholding and
information reporting requirements but rather unify current certification
procedures and forms and clarify reliance standards. The new regulations
require, however, that a foreign person furnish its taxpayer identification
number in certain circumstances to claim a reduction in U.S. federal withholding
tax and new rules are provided for foreign persons that hold debt instruments
through a foreign intermediary. The new regulations are generally effective for
payments made after December 31, 2000, subject to certain transition rules. You
should consult your own tax advisor with respect to the impact, if any, of the
new regulations.

APPLICABLE TAX TREATIES

     If you are a Non-United States Holder, you should consult with your own tax
advisor as to any applicable income tax treaties which may provide for a lower
rate of withholding tax, exemption from a reduction of branch profits tax, or
other rules different from those rules under United States federal tax laws.

     The underwriting agreement provides that the obligations of the
underwriters to purchase the notes included in this offering are subject to
approval of legal matters by counsel and to other conditions. The underwriters
are obligated to purchase all the notes if they purchase any of the notes.

     The underwriters propose to offer some of the notes directly to the public
at the public offering price set forth on the cover page of this prospectus
supplement and some of the notes to certain dealers at the public offering price
less a concession not to exceed 0.40% of the principal amount of the notes. The
underwriters may allow, and dealers may reallow a concession not to exceed 0.25%
of the principal amount of the notes on sales to other dealers. After the
initial offering of the notes to the public, the representatives may change the
public offering price and concessions.

     The following table shows the underwriting discounts and commissions that
we are to pay to the underwriters in connection with this offering (expressed as
a percentage of the principal amount of the notes).



                                                              PAID BY EL PASO

Per note....................................................      0.650%


     In connection with the offering, Salomon Smith Barney, on behalf of the
underwriters, may purchase and sell notes in the open market. These transactions
may include over-allotment, syndicate covering transactions and stabilizing
transactions. Over-allotment involves syndicate sales of notes in excess of the
principal amount of notes to be purchased by the underwriters in the offering,
which creates a syndicate short position. Syndicate covering transactions
involve purchases of the notes in the open market after the distribution has
been completed in order to cover syndicate short positions. Stabilizing
transactions consist of certain bids or purchases of notes made for the purpose
of preventing or retarding a decline in the market price of the notes while the
offering is in progress.

     The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession for a syndicate member when Salomon
Smith Barney, in covering syndicate short positions or making stabilizing
purchases, repurchases notes originally sold by that syndicate member.

     Any of these activities may have the effect of preventing or retarding a
decline in the market price of the notes. They may also cause the price of the
notes to be higher than the price that otherwise would exist in the open market
in the absence of these transactions. The underwriters may conduct these
transactions in the over-the-counter market or otherwise. If the underwriters
commence any of these transactions, they may discontinue them at any time.

     We estimate that our total expenses for this offering, not including
underwriting discounts and commissions, will be $150,000.

     The underwriters have performed investment banking and advisory services
for us from time to time for which they have received customary fees and
expenses. The underwriters may, from time to time, engage in transactions with
and perform services for us in the ordinary course of their business. Salomon
Smith Barney is an affiliate of Citibank, N.A., which is, among other things, a
lender to El Paso under its existing revolving credit facility. BNP Paribas
Securities Corp., BNY Capital Markets, Inc. and TD Securities (USA) Inc. are
also affiliates of other lenders to El Paso under its existing revolving credit
facility. Citibank, N.A. and such other affiliates will receive their
proportionate share of any repayment by El Paso of amounts outstanding under
such facility from the proceeds of any offering of the notes.

     We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make because of any of those
liabilities.

                                 LEGAL MATTERS

     The validity of the notes offered hereby and certain United States federal
income taxation matters will be passed upon for El Paso by Andrews & Kurth

                         CAUTIONARY STATEMENT REGARDING
                           FORWARD-LOOKING STATEMENTS

     We have made statements in this document and in documents that we have
incorporated by reference into this document that constitute forward-looking
statements, as that term is defined in the Private Securities Litigation Reform
Act of 1995. These statements are subject to risks and uncertainties.
Forward-looking statements include information concerning possible or assumed
future results of operations of El Paso. These statements may relate to, but are
not limited to, information or assumptions about earnings per share, capital and
other expenditures, dividends, financing plans, capital structure, cash flow,
pending legal proceedings and claims, including environmental matters, future
economic performance, operating income, cost savings, management's plans, goals
and objectives for future operations and growth and markets for the stock of El
Paso. These forward-looking statements generally are accompanied by words such
as "intend," "anticipate," "believe," "estimate," "expect," "should" or similar
expressions. You should understand that these forward-looking statements are
estimates reflecting the best judgment of senior management of El Paso, not
guarantees of future performance. They are subject to a number of assumptions,
risks and uncertainties that could cause actual results to differ materially
from those expressed or implied in the forward-looking statements. Important
factors that could cause actual results to differ materially from estimates or
projections contained in forward-looking statements include, among others, the
following:

     - the risk that earnings may be adversely affected by fluctuating energy
       prices;

     - the risk that rates charged to customers may be reduced by governmental
       authorities;

     - the highly competitive nature of the natural gas transportation,
       gathering, processing and storage businesses, the oil and gas exploration
       and production business, the energy marketing and power generation
       industries, the crude oil refining and chemical production businesses and
       the coal mining business;

     - the risk of favorable customer contracts expiring or being renewed on
       less attractive terms;

     - the timing and success of our exploration and development drilling
       programs, which would affect production levels and reserves;

     - changes to our estimates of oil, gas and coal reserves;

     - the risk of financial losses arising out of derivative transactions;

     - risks incident to the drilling and operation of oil and gas wells;

     - risks incident to operating crude oil refineries, chemical plants and
       coal mines;

     - future drilling, production and development costs, including drilling rig
       rates;

     - the costs of environmental liabilities, regulations and litigation;

     - the impact of operational hazards;

     - the risk that required regulatory approvals for proposed pipeline,
       storage and power generation projects may be delayed or may only be
       granted on terms that are unacceptable or significantly less favorable
       than anticipated;

     - the risks associated with future weather conditions;

     - the risk that our telecommunications strategy may not be successful;

     - the risk that the former businesses of The Coastal Corporation may not be
       successfully integrated with our businesses;

                                        1
   22

     - the risk that we may not fully realize the benefits expected to result
       from our merger with The Coastal Corporation;

     - the impact of the loss of key employees; and

     - the risk that other firms will further expand into markets in which we
       operate.

     These factors are more fully described in our Current Report on Form 8-K
filed March 23, 2001 and our 2000 Annual Report on Form 10-K under the heading
"Risk Factors and Cautionary Statement for Purposes of the "Safe Harbor"
Provisions of the Private Securities Litigation Reform Act of 1995" and are
incorporated herein by reference. Other factors that could cause actual results
to differ materially from estimates and projections contained in forward-looking
statements are described in the other documents that we incorporated by
reference into this document. In addition, we can give you no assurance that:

     - we have correctly identified and assessed all of the factors affecting
       our businesses;

     - the publicly available and other information with respect to these
       factors on which we have based our analysis is complete or correct;

     - our analysis is correct; or

     - our strategies, which are based in part on this analysis, will be
       successful.

     Accordingly, you should not place undue reliance on forward-looking
statements, which speak only as of the date of this prospectus, or, in the case
of documents incorporated by reference, the date of those documents.

     All subsequent written and oral forward-looking statements attributable to
us or any person acting on our behalf are expressly qualified in their entirety
by the cautionary statements contained or referred to in this section. We do not
undertake any obligation to release publicly any revisions to these
forward-looking statements to reflect events or circumstances after the date of
this prospectus or to reflect the occurrence of unanticipated events.

                              EL PASO CORPORATION

BUSINESS

     We are a global energy company with operations that span the wholesale
energy value chain, from energy production and extraction to power generation.

     Our principal operations include:

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

     - marketing of energy and energy-related commodities and products;

     - generation of power;

     - refining of petroleum;

     - production of chemicals;

     - development and operation of energy infrastructure facilities;

     - exploration and production of natural gas and oil; and

     - mining of coal.

     Our Pipelines segment owns or has interests in approximately 60,000 miles
of interstate natural gas pipelines in the U.S. and internationally. In the
U.S., our systems connect the nation's principal natural gas supply regions to
the five largest consuming regions in the United States: the Gulf Coast,
California, the Northeast, the Midwest, and the Southeast. These operations
represent one of the largest, and only, integrated coast-to-coast mainline
natural gas transmission system in the U.S. Our U.S. pipeline systems also own
or have interests in over 425 billion cubic feet of storage capacity used to
provide a variety of services to our customers. Our international pipeline
operations include access from our U.S. based systems into Canada and Mexico as
well as interests in three major operating natural gas transmission systems in
Australia.

     Our Merchant Energy segment is involved in a broad range of activities in
the energy marketplace including asset ownership, trading and risk management
and financial services. We are one of North America's largest wholesale energy
commodity marketers and traders, and buy, sell, and trade natural gas, power,
crude oil, refined products, coal, and other energy commodities in the U.S. and
internationally. We are also a significant non-utility owner of electric
generating capacity with 84 facilities in 20 countries. Our four refineries have
the capacity to process 538,000 barrels of crude oil per day and produce a
variety of gasolines and other products. We also produce agricultural and
industrial chemicals and petrochemicals at seven facilities in the U.S. and
Canada. Our coal operations produce high-quality, bituminous coal with reserves
in Kentucky, Virginia, and West Virginia. Most recently, we have announced our
expansion into the liquefied natural gas business, capitalizing upon the U.S.
and worldwide demand for natural gas. The financial services businesses of
Merchant Energy invest in emerging businesses to facilitate growth in the U.S.
and Canadian energy markets. As a global energy merchant, we evaluate and
measure risks inherent in the markets we serve, and use sophisticated systems
and integrated risk management techniques to manage those risks.

     Our Field Services segment provides natural gas gathering, products
extraction, fractionation, dehydration, purification, compression and intrastate
transmission services. These services include gathering of natural gas from more
than 15,000 natural gas wells with approximately 24,000 miles of natural gas
gathering and natural gas liquids pipelines, and 35 natural gas processing,
treating, and fractionation facilities located in some of the most prolific and
active production areas in the U.S., including the San Juan Basin, east and
south Texas, Louisiana, the Gulf of Mexico, and the Rocky Mountains. We conduct
our intrastate transmission operations through interests in six intrastate
systems, which serve a majority of the metropolitan areas and industrial load
centers in Texas as well as markets in Louisiana. Our primary vehicle for growth
and development of midstream energy assets is El Paso Energy
                                        4
   25

Partners, L.P., a publicly traded master limited partnership of which our
subsidiary is the general partner. Through Energy Partners, we provide natural
gas and oil gathering and transportation, storage, and other related services,
principally in the Gulf of Mexico.

     Our Production segment leases approximately 5 million net acres in 16
states, including Colorado, Kansas, Louisiana, New Mexico, Texas, Oklahoma,
Utah, Wyoming, and Arkansas, as well as the Gulf of Mexico. We also have
exploration and production rights in Australia, Brazil, Canada, Hungary,
Indonesia, and Turkey. During 2000, daily equivalent natural gas production
exceeded 1.6 billion cubic feet per day, and our reserves at December 31, 2000,
were approximately 6.4 trillion cubic feet of natural gas equivalents.

     In addition to our energy activities, we have announced a
telecommunications strategy that will leverage our knowledge of the commodity
and capital markets into the emerging telecommunications market. Our strategy
involves:

     - accessing fiber deep within metropolitan markets to aggregate supply in
       major U.S. cities;

     - utilizing fiber rings and key points of interconnection of major carriers
       and service providers to allow for liquidity to develop in major markets;
       and

     - assembling a high capacity thin fiber national long-haul backbone.

     We will overlay against this asset base a merchant-based operating support
system and valuation models that will allow us to apply the merchant skills
developed in our core commodity business to the rapidly changing
telecommunications markets.

     Our principal executive offices are located in the El Paso Building at 1001
Louisiana Street, Houston, Texas 77002, and our telephone number at that address
is (713) 420-2600.

                                   THE TRUSTS

     Each of El Paso Capital Trust II and El Paso Capital Trust III is a
statutory business trust created under Delaware law through the filing of a
certificate of trust with the Delaware Secretary of State. Each trust's business
is defined in a declaration of trust which we have executed, as sponsor for each
of the trusts. Officers of El Paso will be the administrative trustees, as
defined below, for each of the trusts. Each declaration will be amended and
restated before any trust preferred securities are sold by that trust. Each
declaration will also be qualified as an indenture under the Trust Indenture Act
of 1939, as amended. Each trust exists for the exclusive purposes of:

     - issuing and selling the trust preferred securities and the trust common
       securities;

     - investing the gross proceeds from the sale of the trust preferred
       securities in subordinated debt securities issued by us; and

     - engaging in only those other activities necessary or incidental to these
       purposes.

     We will, directly or indirectly, in connection with an offering of trust
preferred securities by an El Paso Trust purchase trust common securities in an
aggregate liquidation amount equal to 3% of the total capital of the trust.

     Each trust's business and affairs will be conducted by its trustees. A
majority of the trustees of each trust will be administrative trustees and will
be persons who are employees or officers of or affiliated with us. One trustee
of each trust will be a financial institution that will be unaffiliated with us
and that will act as property trustee and as indenture trustee for purposes of
the Trust Indenture Act, as described in the applicable prospectus supplement.
In addition, unless the property trustees maintain a principal place of business
in the State of Delaware, and otherwise meet the requirements of applicable law,
one trustee of each trust, the Delaware trustee, will have its principal place
of business or reside in the State of Delaware. The administrative trustees and
the property trustees, together with the Delaware trustee, are referred to in
this document as the "trustees." Each trust's business and affairs will be
conducted by the administrative trustees appointed by us, as the direct or
indirect holder of all the trust common securities. Except in limited
circumstances, we, as the holder of the trust common securities, will be
entitled to appoint, remove or replace any of, or increase or reduce the number
of, the trustees of a trust. The declaration of each trust will govern the
duties and obligations of the trustees. We will pay and guarantee all fees and
expenses related to the trusts and the offering of trust securities.

     The office of the Delaware Trustee for each El Paso Trust in the State of
Delaware is 1201 Market Street, Wilmington, Delaware 19801. The principal place
of business of each El Paso Trust will be c/o El Paso Corporation, El Paso
Building, 1001 Louisiana Street, Houston, Texas 77002, and its telephone number
is (713) 420-2600.

                                USE OF PROCEEDS

     We will use the net proceeds we receive from the sale of the securities
offered by this prospectus for general corporate purposes unless we specify
otherwise in an applicable prospectus supplement. We may invest any funds we do
not require immediately for general corporate purposes in marketable securities
and short-term investments. The trusts will use all proceeds received from the
sale of the trust preferred securities to purchase subordinated debt securities
from us.

  Preference Stock Dividend Requirements(1)...........  2.62x    2.53x    --(2)   --(2)   2.04x


- ---------------

(1) The ratio of earnings to combined fixed charges and preferred and preference
    stock dividend requirements for each of the periods presented is the same as
    the ratio of earnings to fixed charges since we have no outstanding
    preferred stock or preference stock and, therefore, no dividend
    requirements.

(2) Earnings were inadequate to cover fixed charges by $549 million in 1998 and
    $407 million in 1999.

     For purposes of computing these ratios, earnings means income (loss) from
continuing operations before:

     - income taxes;

     - minority interest in majority-owned subsidiaries;

     - interest expense, not including interest on rate refunds;

     - amortization of debt costs;

     - that portion of rental expense that we believe to represent an interest
       factor; and

     - adjustment to equity earnings to reflect actual distributions from equity
       investments.

     Fixed charges means the sum of the following:

     - interest cost, not including interest on rate refunds;

     - amortization of debt costs;

     - that portion of rental expense that we believe to represent an interest
       factor;

     - the pre-tax preferred stock dividend requirements of majority-owned
       subsidiaries; and

     - minority interest in majority-owned subsidiaries.

                       DESCRIPTION OF THE DEBT SECURITIES

     Any debt securities we offer will be our direct, unsecured general
obligations. The debt securities will be either senior debt securities or
subordinated debt securities and will be issued under one or more separate
indentures between us and The Chase Manhattan Bank, as indenture trustee. Senior
debt securities will be issued under a "senior indenture" and subordinated debt
securities will be issued under a "subordinated indenture." Together the senior
indenture and the subordinated indenture are called "indentures."

     We have summarized selected provisions of the indentures below. The
following description is a summary of the material provisions of the indentures.
It does not restate those agreements in their entirety. We urge you to read each
of the indentures because each one, and not this description, defines your
rights as holders of the debt securities. A senior indenture and a subordinated
indenture between us and The Chase Manhattan Bank, as trustee, have been filed
as exhibits to the registration statement.

GENERAL

     The debt securities will be our direct, unsecured obligations. The senior
debt securities will rank equally with all of our other senior and
unsubordinated debt. The subordinated debt securities will have a junior
position to all of our senior debt securities.

     If El Paso Capital Trust II or El Paso Capital Trust III issues trust
preferred securities, we will also issue subordinated debt securities to the
trust or a trustee of either trust. If the trusts are subsequently dissolved
upon the occurrence of the events described in the prospectus supplement
relating to the trust preferred securities, the trusts or trustees may
distribute these subordinated debt securities ratably to the holders of trust
preferred securities.

     A prospectus supplement and a supplemental indenture relating to any series
of debt securities being offered will include specific terms relating to the
offered debt securities. These terms will include some or all of the following:

     - the title and type of the debt securities;

     - the total principal amount of the debt securities and the currency, if
       other than U.S. dollars, in which such notes are denominated;

     - the percentage of the principal amount at which the debt securities will
       be issued and any payments due if the maturity of the debt securities is
       accelerated;

     - the dates on which the principal of the debt securities will be payable
       and the terms on which any such maturity date may be extended;

     - the interest rate which the debt securities will bear and the interest
       payment dates for the debt securities;

     - the form of the subordinated debt securities we will issue to the trusts
       or a trustee if the trusts issue trust preferred securities;

     - in the case of subordinated debt securities issued to the trusts or
       trustees, the right to extend payment periods and the duration of that
       extension;

     - any optional redemption periods;

     - any sinking fund or other provisions that would obligate us to repurchase
       or otherwise redeem some or all of the debt securities;

     - any changes to or additional events of defaults or covenants;

     - any special tax implications of the debt securities, including provisions
       for original issue discount securities, if offered;

                                        8
   29

     - restrictions on the declaration of dividends or requiring the maintenance
       of any asset ratio or the creation or maintenance of reserves; and

     - any other terms of the debt securities.

     None of the indentures limits the amount of debt securities that may be
issued. Each indenture allows debt securities to be issued up to the principal
amount that we may authorize and may be in any currency or currency unit we
designate.

     Debt securities of a series may be issued in registered, bearer, coupon or
global form.

DENOMINATIONS

     The prospectus supplement for each issuance of debt securities will state
whether the securities will be issued in registered form of $1,000 each or
multiples of $1,000 or bearer form of $5,000 each.

SUBORDINATION

     Under the subordinated indenture, payment of the principal, interest and
any premium on the subordinated debt securities will generally be subordinated
and junior in right of payment to the prior payment in full of all senior debt
securities. The subordinated indenture states that no payment of principal,
interest and any premium on the subordinated debt securities may be made in the
event:

     - of any insolvency, bankruptcy or similar proceeding involving us or our
       property, or

     - we fail to pay the principal, interest, any premium or any other amounts
       on any senior debt when due.

     The subordinated indenture will not limit the amount of senior debt that we
may incur.

     Senior debt includes all notes or other unsecured evidences of
indebtedness, including guarantees given by us, for money borrowed by us, not
expressly subordinate or junior in right of payment to any of our other
indebtedness.

CONSOLIDATION, MERGER OR SALE

     Each indenture generally permits a consolidation or merger between us and
another corporation. They also permit us to sell all or substantially all of our
property and assets. If this occurs, the remaining or acquiring corporation will
assume all of our responsibilities and liabilities under the indentures,
including the payment of all amounts due on the debt securities and performance
of the covenants in the indentures. However, we will consolidate or merge with
or into any other corporation or sell all or substantially all of our assets
only according to the terms and conditions of the indentures. The remaining or
acquiring corporation will be substituted for us in the indentures with the same
effect as if it had been an original party to the indentures. After that the
successor corporation may exercise our rights and powers under any indenture, in
our name or in its own name. Any act or proceeding required or permitted to be
done by our board or any of our officers may be done by the board or officers of
the successor corporation. If we sell all or substantially all of our assets, we
will be released from all our liabilities and obligations under any indenture
and under the debt securities.

MODIFICATION OF INDENTURES

     Under each indenture our rights and obligations and the rights of the
holders may be modified with the consent of the holders of a majority in
aggregate principal amount of the outstanding debt securities of each series
affected by the modification. No modification of the principal or interest
payment terms, and no modification reducing the percentage required for
modifications, is effective against any holder without its consent.

   30

EVENTS OF DEFAULT

     "Event of default" when used in an indenture, will mean any of the
following:

     - failure to pay the principal of or any premium on any debt security when
       due;

     - failure to pay interest on any debt security for 30 days;

     - failure to perform any other covenant in the indenture that continues for
       60 days after being given written notice;

     - certain events in our bankruptcy, insolvency or reorganization; or

     - any other event of default included in any indenture or supplemental
       indenture.

     An event of default for a particular series of debt securities does not
necessarily constitute an event of default for any other series of debt
securities issued under an indenture. The trustee may withhold notice to the
holders of debt securities of any default, except in the payment of principal or
interest, if it considers such withholding of notice to be in the best interests
of the holders.

     If an event of default for any series of debt securities occurs and
continues, the trustee or the holders of at least 25% in aggregate principal
amount of the debt securities of the series may declare the entire principal of
all the debt securities of that series to be due and payable immediately. If
this happens, subject to certain conditions, the holders of a majority of the
aggregate principal amount of the debt securities of that series can void the
declaration.

     Other than its duties in case of a default, a trustee is not obligated to
exercise any of its rights or powers under any indenture at the request, order
or direction of any holders, unless the holders offer the trustee reasonable
indemnity. If they provide this reasonable indemnification, the holders of a
majority in principal amount of any series of debt securities may direct the
time, method and place of conducting any proceeding or any remedy available to
the trustee, or exercising any power conferred upon the trustee, for any series
of debt securities.

COVENANTS

  General

     Under the indentures, we will:

     - pay the principal of, and interest and any premium on, the debt
       securities when due;

     - maintain a place of payment;

     - deliver a report to the trustee at the end of each fiscal year reviewing
       our obligations under the indentures; and

     - deposit sufficient funds with any paying agent on or before the due date
       for any principal, interest or premium.

     The senior indenture provides that we will not, nor will we permit any
restricted subsidiary to, create, assume, incur or suffer to exist any lien upon
any principal property, whether owned or leased on the date of the senior
indenture or thereafter acquired, to secure any of our debt or any other person
(other than the senior debt securities issued under the senior indenture),
without causing all of the senior debt securities outstanding under the senior
indenture to be secured equally and ratably with, or prior to, the new debt so
long the new debt is so secured. This restriction does not prohibit us from
creating the following:

          (i) any lien upon any of our property or assets or any restricted
     subsidiary in existence on the date of the senior indenture or created
     pursuant to an "after-acquired property" clause or similar term

                                        10
   31

     in existence on the date of the senior indenture or any mortgage, pledge
     agreement, security agreement or other similar instrument in existence on
     the date of the senior indenture;

          (ii) any lien upon any property or assets created at the time of
     acquisition of such property or assets by or any of our restricted
     subsidiaries or within one year after such time to secure all or a portion
     of the purchase price for such property or assets or debt incurred to
     finance such purchase price, whether such debt was incurred prior to, at
     the time of or within one year of such acquisition;

          (iii) any lien upon any property or assets existing on the property at
     the time of the acquisition of the property by us or any of our restricted
     subsidiaries (whether or not the obligations secured are assumed by us or
     any of our restricted subsidiaries);

          (iv) any lien upon any property or assets of a person existing on the
     property at the time that person becomes a restricted subsidiary by
     acquisition, merger or otherwise;

          (v) the assumption by us or any of our restricted subsidiaries of
     obligations secured by any lien existing at the time of the acquisition by
     us or any of our restricted subsidiaries of the property or assets subject
     to such lien or at the time of the acquisition of the person which owns
     that property or assets;

          (vi) any lien on property to secure all or part of the cost of
     construction or improvements on the property or to secure debt incurred
     prior to, at the time of, or within one year after completion of such
     construction or making of such improvements, to provide funds for any such
     purpose;

          (vii) any lien on any oil, gas, mineral and processing and other plant
     properties to secure the payment of costs, expenses or liabilities incurred
     under any lease or grant or operating or other similar agreement in
     connection with or incident to the exploration, development, maintenance or
     operation of such properties;

          (viii) any lien arising from or in connection with a conveyance by us
     or any of our restricted subsidiaries of any production payment with
     respect to oil, gas, natural gas, carbon dioxide, sulphur, helium, coal,
     metals, minerals, steam, timber or other natural resources;

          (ix) any lien in favor of us or any of our restricted subsidiaries;

          (x) any lien created or assumed by us or any of our restricted
     subsidiaries in connection with the issuance of debt the interest on which
     is excludable from gross income of the holder of such debt pursuant to the
     Internal Revenue Code of 1986, as amended, or any successor statute, for
     the purpose of financing, in whole or in part, the acquisition or
     construction of property or assets to be used by us or any of our
     subsidiaries;

          (xi) any lien upon property or assets of any foreign restricted
     subsidiary to secure debt of that foreign restricted subsidiary;

          (xii) permitted liens (as defined below);

          (xiii) any lien upon any additions, improvements, replacements,
     repairs, fixtures, appurtenances or component parts thereof attaching to or
     required to be attached to property or assets pursuant to the terms of any
     mortgage, pledge agreement, security agreement or other similar instrument,
     creating a lien upon such property or assets permitted by clauses (i)
     through (xii), inclusive, above; or

          (xiv) any extension, renewal, refinancing, refunding or replacement
     (or successive extensions, renewals, refinancing, refundings or
     replacements) of any lien, in whole or in part, that is referred to in
     clauses (i) through (xiii), inclusive, above, or of any debt secured
     thereby; provided, however, that the principal amount of debt secured shall
     not exceed the greater of the principal amount of debt so secured at the
     time of such extension, renewal, refinancing, refunding or replacement and
     the original principal amount of debt so secured (plus in each case the
     aggregate amount of premiums, other payments, costs and expenses required
     to be paid or incurred in connection with such extension, renewal,
     refinancing, refunding or replacement); provided further, however, that
     such extension,

                                        11
   32

     renewal, refinancing, refunding or replacement shall be limited to all or a
     part of the property (including improvements, alterations and repairs on
     such property) subject to the encumbrance so extended, renewed, refinanced,
     refunded or replaced (plus improvements, alterations and repairs on such
     property).

     Notwithstanding the foregoing, under the senior indenture, we may, and may
permit any restricted subsidiary to, create, assume, incur, or suffer to exist
any lien upon any principal property to secure our debt or any person (other
than the senior debt securities) that is not excepted by clauses (i) through
(xiv), inclusive, above without securing the senior debt securities issued under
the senior indenture, provided that the aggregate principal amount of all debt
then outstanding secured by such lien and all similar liens, together with all
net sale proceeds from sale-leaseback transactions (excluding sale-leaseback
transactions permitted by clauses (i) through (iv), inclusive, of the first
paragraph of the restriction on sale-leasebacks covenant described below) does
not exceed 15% of consolidated net tangible assets.

     The senior indenture also provides that we will not, nor will we permit any
restricted subsidiary to, engage in a sale-leaseback transaction, unless: (i)
such sale-leaseback transaction occurs within one year from the date of
acquisition of the principal property subject thereto or the date of the
completion of construction or commencement of full operations on such principal
property, whichever is later; (ii) the sale-leaseback transaction involves a
lease for a period, including renewals, of not more than three years; (iii) we
or any of our restricted subsidiaries would be entitled to incur debt secured by
a lien on the principal property subject thereto in a principal amount equal to
or exceeding the net sale proceeds from such sale-leaseback transaction without
securing the senior debt securities; or (iv) we or any of our restricted
subsidiaries, within a one-year period after such sale-leaseback transaction,
applies or causes to be applied an amount not less than the net sale proceeds
from such sale-leaseback transaction to (A) the repayment, redemption or
retirement of funded debt of us or any such restricted subsidiary, or (B)
investment in another principal property.

     Notwithstanding the foregoing, under the senior indenture we may, and may
permit any restricted subsidiary to, effect any sale-leaseback transaction that
is not excepted by clauses (i) through (iv), inclusive, of the above paragraph,
provided that the net sale proceeds from such sale-leaseback transaction,
together with the aggregate principal amount of outstanding debt (other than the
senior debt securities) secured by liens upon principal properties not excepted
by clauses (i) through (xiv), inclusive, of the first paragraph of the
limitation on liens covenant described above, do not exceed 15% of the
consolidated net tangible assets.

  Subordinated Indenture Covenants

     If we issue subordinated debt securities to an El Paso Trust in connection
with the issuance of trust securities by the El Paso Trust and

     - an event of default under the subordinated indenture has occurred,

     - we are in default of our payment obligations under the related trust
       guarantee or the guarantee of the trust common securities, or

     - we have elected to defer payments of interest on the subordinated debt
       securities by extending the interest payment period as provided in the
       subordinated indenture, and the interest payment period, or any extension
       of it, is continuing, then

we will be subject to restrictions regarding the declaration or payment of
dividends on, and the making of guarantee payments with respect to, any of our
capital stock, and the making of any payment of interest, principal or premium,
if any, on, or the repayment, repurchase or redemption of, any debt securities
(including guarantees) issued by us which rank the same as or junior to the
subordinated debt securities. These restrictions will be more fully described in
the prospectus supplement applicable to the particular series of subordinated
debt securities issued to a trust.

                                        12
   33

     In the event we issue subordinated debt securities to an El Paso Trust in
connection with the El Paso Trust's issuance of trust securities, for so long as
such trust securities remain outstanding, we will covenant in the declaration,
the guarantees or the supplemental indenture to the subordinated indenture with
respect to such El Paso Trust:

     - to directly or indirectly maintain 100% ownership of the common
       securities of the El Paso Trust; however, any permitted successor to us
       under the subordinated indenture may succeed to our ownership of the
       trust common securities and

     - not to voluntarily terminate, wind-up or liquidate the El Paso Trust,
       except in connection with

          (i) the distribution of subordinated debt securities to the holders of
     trust securities in liquidation of the trust,

          (ii) the redemption of all of the trust securities of the trust, or

          (iii) certain mergers, consolidations or amalgamations, each as
     permitted by the declaration of the trust.

We will also covenant to use our commercially reasonable efforts, consistent
with the terms and provisions of the declaration of the El Paso Trust, to cause
the trust to remain classified as a grantor trust and not taxable as a
corporation for United States federal income tax purposes.

     If the El Paso Trusts issue trust preferred securities and we issue
subordinated debt securities to the trust or a trustee in connection with the
issuance of the trust preferred securities and (1) an event of default as
defined in this document has occurred, (2) we are in default with respect to our
payment of any obligations under the related trust guarantee or the guarantee of
the trust common securities or (3) we have given notice of our election to defer
payments of interest on these subordinated debt securities by extending the
interest payment period as provided in the indenture governing these
subordinated debt securities, and this interest payment period, or any extension
of this interest payment period, is continuing, we will be subject to
restrictions regarding

     - the declaration of payment of dividends on, and the making of guarantee
       payments with respect to, any of our capital stock; and

     These restrictions will be described in more detail in the prospectus
supplement relating to these subordinated debt securities.

     If the El Paso Trusts issue trust preferred securities and we issue
subordinated debt securities to the trust or a trustee in connection with the
issuance of the trust preferred securities, for so long as the trust preferred
securities remain outstanding, we will covenant in the declaration of the
trusts, the related guarantees or the indenture governing these subordinated
debt securities:

     - To directly or indirectly maintain 100% ownership of the common

                                        14
   35

      - Not to voluntarily terminate, wind-up or liquidate either El Paso
        Capital Trust II or El Paso Capital Trust III, as the case may be,
        except in connection with

           - the distribution of subordinated debt securities to the holders of
             trust preferred securities in liquidation of either trust;

             or

           - mergers, consolidations or amalgamations permitted by the
             declaration of either trust.

     We will also covenant to use our commercially reasonable efforts,
consistent with the terms and provisions of the declaration of either trust, to
cause each trust to remain classified as a grantor trust and not taxable as a
corporation for U.S. federal income tax purposes.

PAYMENT AND TRANSFER

     Unless we specify otherwise in a prospectus supplement, we will pay
principal, interest and any premium on the debt securities, and they may be
surrendered for payment or transferred, at the offices of the trustee. We will
make payment on registered securities by check mailed to the persons in whose
names the debt securities are registered or by transfer to an account maintained
by the registered holder on days specified in the indentures or any prospectus
supplement. If we make debt securities payments in other forms, we will specify
the form and place in a prospectus supplement.

     We will maintain a corporate trust office of the trustee or another office
or agency for the purpose of transferring or exchanging fully registered
securities, without the payment of any service charge except for any tax or
governmental charge.

GLOBAL SECURITIES

     We may issue one or more series of the debt securities as permanent global
debt securities deposited with a depositary. Unless otherwise indicated in the
prospectus supplement, the following is a summary of the depository arrangements
applicable to debt securities issued in permanent global form and for which The
Depositary Trust Company (DTC) acts as depositary.

     Each global debt security will be deposited with, or on behalf of, DTC, as
depositary, or its nominee and registered in the name of a nominee of DTC.
Except under the limited circumstances described below, global debt securities
are not exchangeable for definitive certificated debt securities.

     Ownership of beneficial interests in a global debt security is limited to
participants that have accounts with DTC or its nominee, or persons that may
hold interests through those participants. In addition, ownership of beneficial
interests by participants in a global debt security will be evidenced only by,
and the transfer of that ownership interest will be effected only through,
records maintained by DTC or its nominee for a global debt security. Ownership
of beneficial interests in a global debt security by persons that hold through
participants will be evidenced only by, and the transfer of that ownership
interest within that participant will be effected only through, records
maintained by that participant. DTC has no knowledge of the actual beneficial
owners of the debt securities. Beneficial owners will not receive written
confirmation from DTC of their purchase, but beneficial owners are expected to
receive written confirmations providing details of the transaction, as well as
periodic statements of their holdings, from the participants through which the
beneficial owners entered the transaction. The laws of some jurisdictions
require that certain purchasers of securities take physical delivery of such
securities in definitive form. Such laws may impair the ability to transfer
beneficial interests in a global debt security.

     We will make payment of principal of, and interest on, debt securities
represented by a global debt security registered in the name of or held by DTC
or its nominee will be made to DTC or its nominee, as the case may be, as the
registered owner and holder of the global debt security representing those debt
securities. DTC has advised us that upon receipt of any payment of principal of,
or interest on, a global debt security, DTC will immediately credit accounts of
participants on its book-entry registration and

                                        15
   36

transfer system with payments in amounts proportionate to their respective
beneficial interests in the principal amount of that global debt security as
shown in the records of DTC. Payments by participants to owners of beneficial
interests in a global debt security held through those participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in "street name," and will be the sole responsibility of those participants,
subject to any statutory or regulatory requirements that may be in effect from
time to time.

     Neither we, any trustee nor any of our respective agents, will be
responsible for any aspect of the records of DTC, any nominee or any participant
relating to, or payments made on account of, beneficial interests in a permanent
global debt security or for maintaining, supervising or reviewing any of the
records of DTC, any nominee or any participant relating to such beneficial
interests.

     A global debt security is exchangeable for definitive debt securities
registered in the name of, and a transfer of a global debt security may be
registered to, any person other than DTC or its nominee, only if:

     - DTC notifies us that it is unwilling or unable to continue as depositary
       for that global debt security or at any time DTC ceases to be registered
       under the Exchange Act;

     - we determine in our discretion that the global debt security shall be
       exchangeable for definitive debt securities in registered form; or

     - there shall have occurred and be continuing an event of default or an
       event which, with notice or the lapse of time or both, would constitute
       an event of default under the debt securities.

     Any global debt security that is exchangeable pursuant to the preceding
sentence will be exchangeable in whole for definitive debt securities in
registered form, of like tenor and of an equal aggregate principal amount as the
global debt security, in denominations specified in the applicable prospectus
supplement, if other than $1,000 and integral multiples of $1,000. The
definitive debt securities will be registered by the registrar in the name or
names instructed by DTC. We expect that these instructions may be based upon
directions received by DTC from its participants with respect to ownership of
beneficial interests in the global debt security.

     Except as provided above, owners of the beneficial interests in a global
debt security will not be entitled to receive physical delivery of debt
securities in definitive form and will not be considered the holders of debt
securities for any purpose under the indentures. No global debt security shall
be exchangeable except for another global debt security of like denomination and
tenor to be registered in the name of DTC or its nominee. Accordingly, each
person owning a beneficial interest in a global debt security must rely on the
procedures of DTC and, if that person is not a participant, on the procedures of
the participant through which that person owns its interest, to exercise any
rights of a holder under the global debt security or the indentures.

     We understand that, under existing industry practices, in the event that we
request any action of holders, or an owner of a beneficial interest in a global
debt security desires to give or take any action that a holder is entitled to
give or take under the debt securities or the indentures, DTC would authorize
the participants holding the relevant beneficial interests to give or take that
action, and those participants would authorize beneficial owners owning through
those participants to give or take that action or would otherwise act upon the
instructions of beneficial owners owning through them.

     DTC has advised us that DTC is a limited purpose trust company organized
under the laws of the State of New York, a "banking organization" within the
meaning of the New York Banking Law, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered under the Exchange Act. DTC was created
to hold securities of its participants and to facilitate the clearance and
settlement of securities transactions among its participants in those securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. DTC's
participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. DTC is owned by a number
of its participants and by the New York Stock
                                        16
   37

Exchange, Inc., the American Stock Exchange, Inc. and the National Association
of Securities Dealers, Inc. Access to DTC's book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a participant, either directly
or indirectly. The rules applicable to DTC and its participants are on file with
the SEC.

DEFEASANCE

     We will be discharged from our obligations on the debt securities of any
series at any time if we deposit with the trustee sufficient cash or government
securities to pay the principal, interest, any premium and any other sums due to
the stated maturity date or a redemption date of the debt securities of the
series. If this happens, the holders of the debt securities of the series will
not be entitled to the benefits of the indenture except for registration of
transfer and exchange of debt securities and replacement of lost, stolen or
mutilated debt securities.

     Under U.S. federal income tax laws as of the date of this prospectus, a
discharge may be treated as an exchange of the related debt securities. Each
holder might be required to recognize gain or loss equal to the difference
between the holder's cost or other tax basis for the debt securities and the
value of the holder's interest in the trust. Holders might be required to
include as income a different amount than would be includable without the
discharge. Prospective investors should seek tax advice to determine their
particular consequences of a discharge, including the applicability and effect
of tax laws other than the U.S. federal income tax laws.

GOVERNING LAW

     Each indenture and the debt securities will be governed by and construed in
accordance with the laws of the State of New York.

NOTICES

     Notices to holders of debt securities will be given by mail to the
addresses of such holders as they appear in the security register.

COMMON STOCK

     We are currently authorized by our charter to issue up to 750,000,000
shares of common stock. The holders of common stock are entitled to one vote for
each share held of record on all matters submitted to a vote of stockholders.
Subject to preferences that may be applicable to any outstanding preferred
stock, holders of common stock are entitled to receive ratably dividends which
are declared by our board of directors out of funds legally available for such a
purpose. In the event of our liquidation, dissolution, or winding up, holders of

PREFERRED STOCK

     Our board of directors, without any further action by our stockholders, is
authorized to issue up to 50,000,000 shares of preferred stock and to divide the
preferred stock into one or more series. The Board may fix by resolution or

qualifications, limitations, or restrictions of the shares of each such series,
including, but not limited to, dividend rates, conversion rights, voting rights,
terms of redemption and liquidation preferences, and the number of shares
constituting each such series. The issuance of preferred stock may have the
effect of delaying, deterring or preventing a change in control of El Paso.
Preferred stock, upon issuance against full payment of the purchase price
therefor, will be fully paid and nonassessable. The specific terms of a
particular series of preferred stock will be described in the certificate of
designation relating to that series. The description of preferred stock set
forth below does not purport to be complete and is qualified in its entirety by
reference to the certificate of designation relating to the particular series of

by the certificate of designation relating to such series. The certificate of
designation relating to each series will specify the terms of the preferred
stock as follows:

       any accumulated dividends that the holders of shares of each series shall
       be entitled to receive upon the redemption of the shares;

     - The liquidation preference, if any, and any accumulated dividends
       thereon, that the holders of shares of each series shall be entitled to
       receive upon the liquidation, dissolution or winding up of the affairs of
       El Paso;

     - Whether or not the shares of each series will be subject to operation of
       a retirement or sinking fund, and, if so, the extent and manner in which
       any such fund shall be applied to the purchase or redemption of the
       shares of such series for retirement or for other corporate purposes and
       the terms and provisions relating to the operation of such fund;

     - The terms and conditions, if any, on which the shares of each series
       shall be convertible into, or exchangeable for, debt securities, shares
       of any other class or classes of our capital stock, or any series of any
       other class or classes, or of any other series of the same class,
       including the price or prices or the rate or rates of conversion or
       exchange and the method, if any, of adjusting the same;

     - The voting rights, if any, on the shares of each series; and

     As of the date of this offering circular, 200,000 shares of Series B
Mandatorily Convertible Single Reset Preferred Stock are outstanding. Pursuant
to the shareholder rights agreement, our board of directors has designated
7,500,000 shares of Series A preferred stock. A summary description of each of
the shareholder rights agreement, the Series A preferred stock and the Series B
Mandatorily Convertible Single Reset Preferred Stock is set forth below. You
should refer to the full text of the shareholder rights agreement and the
certificate of designation for each series of preferred stock for more complete
descriptions.

SHAREHOLDER RIGHTS AGREEMENT

     In July 1992, the board of directors of El Paso Natural Gas Company, our
predecessor ("EPG"), declared a dividend distribution of one preferred stock
purchase right (an "EPG right") for each share of EPG's common stock par value
$3.00 per share, then outstanding. In July 1997, EPG's board amended EPG's
shareholder rights agreement pursuant to which the EPG rights were issued. All
shares of EPG common stock issued subsequent to July 1992 also included these
EPG rights. In connection with the holding company reorganization effected as of
August 1, 1998, each one-half EPG right then associated with each outstanding
share of EPG common stock was converted into one preferred stock purchase right
(a "right") associated with each share of our common stock. All shares of our
common stock issued after August 1, 1998 will also include a right. Under
conditions specified in the shareholder rights agreement, each right may be
exercised to purchase from us one two-hundredths of a share of a series of our
preferred stock, designated as Series A junior participating preferred stock,
par value $.01 per share (the "Series A preferred stock"), at a price of $75 per
one two-hundredths of a share, subject to adjustment. In January 1999, the
shareholder rights agreement was amended and restated.

     Our charter provides that the holders of a whole share of Series A
preferred stock are entitled to 200 votes per share on all matters submitted to
a vote of our stockholders subject to adjustment. In addition, during any period
that dividends on the Series A preferred stock are in arrears in an amount equal
to six quarterly dividend payments, the holders of Series A preferred stock will
have the right to vote together as a class to elect two of our directors.

     The rights will separate from the common stock and will become exercisable
on the earlier of (1) the first date of the public announcement that a person or
group has acquired or obtained the right to acquire beneficial ownership of 15%
or more of the voting power of all of our outstanding voting securities and (2)
10 business days (or such later date as the board may determine) after the
commencement of, or
                                        19
   40

announcement of an intention to commence, a tender or exchange offer, that would
result in a person or group beneficially owning 15% or more of our voting
securities. If, after the rights become exercisable, we are involved in a merger
or other business combination transaction in which our common stock is exchanged
or changed, or it sells 50% or more of its assets or earning power, each holder
of a right will have the right to purchase at the right's then-current exercise
price, common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
right. If a person becomes the beneficial owner of securities having 15% or more
of the voting power of all of our then-outstanding voting securities (except
pursuant to a "permitted offer"), or if, during any period of such ownership,
there shall be any reclassification of securities or recapitalization of us, or
any merger or consolidation of us with any of our subsidiaries or any other
transaction or series of transactions which has the effect, directly or
indirectly, of increasing by more than 1% the proportionate share of the
outstanding shares of any class of our equity securities or any of our
subsidiaries which is directly or indirectly owned by such person, then for the
next 60 days each right not owned by such person will entitle the holder of the
right to purchase, at the right's then-current exercise price, shares of common
stock or, in the discretion of the board, the number of one two-hundredths of a
shares of series A preferred stock (or in circumstances specified in the
shareholder rights agreement, other of our equity securities with at least the
same economic value as the common stock) having a market value of twice the
right's then-current exercise price. The rights, which have no voting rights,
expire no later than 5:00 p.m., New York time on July 7, 2002. A "permitted
offer" is a tender or exchange offer for all outstanding shares of common stock
which is at a price and on terms determined, prior to the purchase of shares in
such offer, by a majority of the disinterested directors to be adequate and
otherwise in the best interests of us and our stockholders (other than the
person and its affiliates making the offer), taking into account all factors
that such disinterested directors deem relevant. "Disinterested directors" are
directors who are neither our officers nor the officers an acquiring company or
affiliate, associate or representative of such a company, or a person directly
or indirectly proposed or nominated as director by a transaction person (as
defined in the shareholder rights agreement). We may redeem the rights under
circumstances specified in the shareholder rights agreement, prior to their
expiration date at a purchase price of $.01 per right. It is possible that the
existence of the rights may have the effect of delaying, deterring or preventing
our takeover.

     Each share of our common stock issued upon conversion of the debentures
will include a right issued under the shareholder rights agreement.

EL PASO SERIES B MANDATORILY CONVERTIBLE SINGLE RESET PREFERRED STOCK

     In March 2000, we issued 200,000 shares of El Paso Series B Mandatorily
Convertible Single Reset Preferred Stock having an initial aggregate liquidation
preference of $1,000,000,000 in connection with the issuance by Limestone
Electron Trust and Limestone Electron, Inc. of $1,000,000,000 aggregate
principal amount of notes (the "Limestone Notes"). The shares of the El Paso
Series B Mandatorily Convertible Single Reset Preferred Stock were deposited
under a share trust agreement into a trust established for the benefit of the
holders of the Limestone Notes. We are the beneficial owner of the trust. The
preferred shares are to be sold by the trust only if:

     - the Limestone Notes are accelerated as a result of an event of default,
       including, in addition to various defaults under the documentation
       relating to the transactions pursuant to which the Limestone Notes were
       issued, payment defaults by El Paso under debt obligations specified in
       the documentation relating to the transactions;

     - the funds necessary to pay the Limestone Notes upon maturity are not
       timely deposited; or

     - our credit ratings fall below investment grade and our common stock price
       for ten consecutive trading days falls below $27.07, subject to certain
       adjustments.

     The date that the preferred shares are sold by the trust, or under certain
circumstances the date of a failed remarketing of the preferred shares, is the
"Rate Reset Date," and the market price of El Paso common stock on the day such
sale is priced or the date of such failed remarketing is the "Reset Price,"

                                        20
   41

which price is subject to certain antidilution adjustments. If the Limestone
Notes, which mature on March 15, 2003, are timely repaid in full, we expect the
El Paso Series B Mandatorily Convertible Single Reset Preferred Stock will be
retired and canceled.

     No dividends are payable on the El Paso Series B Mandatorily Convertible
Single Reset Preferred Stock prior to the Rate Reset Date. After the Rate Reset
Date, dividends are payable at a rate equal to 7% per annum plus an amount which
is intended to approximate the dividend yield on the El Paso common stock as of
the Rate Reset Date. Such dividends are payable quarterly in arrears and are
cumulative. The amount payable on shares of El Paso Series B Mandatorily
Convertible Single Reset Preferred Stock in the event of a liquidation,
dissolution or winding up of the affairs of El Paso is $5,000 per share,
together with accrued dividends to the date of payment. These dividend and
liquidation rights are senior to the dividend and liquidation rights of the El
Paso common stock and the El Paso Series A Participating Junior Preferred Stock.
The El Paso Series B Mandatorily Convertible Single Reset Preferred Stock is not
redeemable after the Rate Reset Date.

     After the Rate Reset Date and prior to the date on which the El Paso Series
B Mandatorily Convertible Single Reset preferred Stock automatically convert
into shares of El Paso common stock, the holders of the El Paso Series B
Mandatorily Convertible Single Reset Preferred Stock will be entitled to convert
the preferred shares into El Paso common stock based on a conversion price of
110% of the Reset Price. The El Paso Series B Mandatorily Convertible Single
Reset Preferred Stock will be converted automatically into El Paso common stock
on the later to occur of the third anniversary of the Rate Reset Date and March
15, 2006, and holders will also be entitled to receive cash equal to all accrued
dividends. The number of shares of El Paso common stock issuable per share of El
Paso Series B Mandatorily Convertible Single Reset Preferred Stock upon
automatic conversion will equal the quotient of $5,000 divided by a conversion
price which will be between 100% to 110% of the Reset Price, depending on the
market price of El Paso common stock at the time of automatic conversion.

     The holders of El Paso Series B Mandatorily Convertible Single Reset
Preferred Stock generally have no voting rights except as may be required by
statute, but are entitled to certain class voting rights, including the
requirement for approval by the holders of at least a majority thereof to
effect:

     - an amendment to El Paso's certificate of incorporation that would
       adversely affect the powers, rights or preferences of the holders of the
       El Paso Series B Mandatorily Convertible Single Reset Preferred Stock;

     - the authorization or issuance of capital stock ranking senior to the El
       Paso Series B Mandatorily Convertible Single Reset Preferred Stock; or

     - the merger or consolidation of El Paso in which holders of the El Paso
       Series B Mandatorily Convertible Single Reset Preferred Stock do not
       receive or continue to hold a similar interest in the surviving entity,
       subject to certain exceptions.

     If full cumulative dividends on the El Paso Series B Mandatorily
Convertible Single Reset Preferred Stock are not paid for six consecutive
quarters, the holders of the El Paso Series B Mandatorily Convertible Single
Reset Preferred Stock (together with the holders of any other series of capital
stock, including the Series A preferred stock, that are entitled to elect
directors as a result of dividend arrearages) will have the right to elect two
directors to El Paso's Board of Directors until all dividend arrearages have
been paid. If we fail to pay dividends when due on El Paso Series B Mandatorily
Convertible Single Reset Preferred Stock, we are prohibited from paying
dividends on prior stock, including El Paso common stock and Series A preferred
stock, and we and our subsidiaries are prohibited from redeeming or acquiring
junior stock, including El Paso common stock and Series A preferred stock.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

     We are a Delaware corporation subject to Section 203 of the Delaware
General Corporation Law. Generally, Section 203 prohibits a publicly held
Delaware corporation from engaging in a "business

                                        21
   42

combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless (1) prior to such date, either the business combination or
such transaction which resulted in the stockholder becoming an interested
stockholder is approved by the board of directors of the corporation, (2) upon
consummation of the transaction which resulted in the stockholder becoming an
interested stockholder, the interested stockholder owns at least 85% of the
outstanding voting stock, or (3) on or after such date, the business combination
is approved by the board of directors of the corporation and by the affirmative
vote at least 66 2/3% of the outstanding voting stock that is not owned by the
interested stockholder. A "business combination" includes merger, asset sales
and other transactions resulting in a financial benefit to the interested
stockholder. An "interested stockholder" is a person who, together with
affiliates and associates, owns, or, within three years, did own, 15% or more of
the corporation's outstanding voting stock.

EL PASO'S RESTATED CERTIFICATE OF INCORPORATION

     Our charter contains provisions applicable to a merger, consolidation,
asset sale, liquidation, recapitalization, or other business transactions,
including the issuance of our stock ("business combinations"). Our charter
requires the affirmative vote of 51% or more of our voting stock, excluding any
voting stock held by an interested stockholder (defined in our charter as any
person who owns 10% or more of the voting stock and specifically defined
affiliates), with respect to all business combinations involving the interested
stockholder, unless directors who served as such prior to the time the
interested stockholder became an interested stockholder determine by a
two-thirds vote that (1) the proposed consideration meets specified minimum
price criteria, or (2)(A) the interested stockholder holds 80% or more of the
voting stock and (B) the interested stockholder has not received (other than
proportionately as a stockholder) the benefit of any financial assistance from
us, whether in anticipation of or in connection with such business combination.
To meet the minimum price criteria, all stockholders must receive consideration
or retain value per share after the transaction which is not less than the price
per share paid by the interested stockholder. Our charter also requires the
dissemination to stockholders of a proxy or information statement describing the
business combination.

     Our charter also prohibits the taking of any action by written stockholder
consent in lieu of a meeting and the subsequent amendment of our charter to
repeal or alter the above provisions without the affirmative vote of 51% of our
voting stock, excluding voting stock held by any interested stockholder.

                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES

     Each trust may issue in one or more offerings only one series of trust
preferred securities having terms described in the applicable prospectus
supplement. The declaration of each trust authorizes the administrative trustees
to issue on behalf of that trust one series of trust preferred securities. The
declaration of each trust, as amended in connection with the trust's sale of
trust preferred securities, will be qualified as an indenture under the Trust
Indenture Act.

     The trust preferred securities will have such terms, including
distributions, redemption, voting, conversion, exchange, liquidation rights and
such other preferred, deferred or other special rights or such restrictions as
are set forth in the declaration, as amended in connection with the trust's sale
of trust preferred securities or made part of the declaration by the Trust
Indenture Act. You should refer to the prospectus supplement relating to the
trust preferred securities of the trust for specific terms, including:

     - the distinctive designation of the trust preferred securities;

     - the number of trust preferred securities issued by each trust;

     - the annual distribution rate (or method of determining such rate) for
       trust preferred securities issued by the trust and the date or dates upon
       which the distributions are payable;

     - the date or dates or method of determining the date or dates from which
       distributions on trust preferred securities will be cumulative;

                                        22
   43

     - the amount or amounts that will be paid out of the assets of the trust to
       the holders of trust preferred securities upon voluntary or involuntary
       dissolution, winding-up or termination of the trust;

     - the obligation, if any, of the trust to purchase or redeem the trust
       preferred securities and the price or prices at which, the period or
       periods within which, and the terms and conditions upon which, trust
       preferred securities will be purchased or redeemed, in whole or in part,
       pursuant to that obligation;

     - the voting rights, if any, of trust preferred securities in addition to
       those required by law, including the number of votes per trust preferred
       security and any requirement for the approval by the holders of trust
       preferred securities, as a condition to specified action or amendments to
       the declaration of the trust;

     - the terms and conditions, if any, upon which the assets of the trust may
       be distributed to holders of trust preferred securities;

     - provisions regarding convertibility or exchangeability of the trust
       preferred securities for our capital stock or debt securities;

     - if applicable, any securities exchange upon which the trust preferred
       securities will be listed; and

     - any other relevant rights, preferences, privileges, limitations or
       restrictions of trust preferred securities not inconsistent with the
       declaration of the trust or with applicable law.

     We will guarantee all trust preferred securities offered to the limited
extent set forth below under "Description of the Trust Preferred Securities
Guarantees."

     Any U.S. federal income tax considerations applicable to any offering of
trust preferred securities will be described in the applicable prospectus
supplement.

     In connection with the issuance of trust preferred securities, each trust
will issue one series of trust common securities. The declaration of each trust
authorizes the administrative trustees of the trust to issue on behalf of the
trust one series of trust common securities. The amended and restated
declaration of the trust will set forth the terms of the trust common
securities, including terms regarding distributions, redemption, voting,
liquidation rights and any restrictions. The terms of the trust common
securities issued by each trust will be substantially identical to the terms of
the trust preferred securities issued by the trust. The trust common securities
will rank equally, and payments will be made on the trust common securities pro
rata, with the trust preferred securities. However, upon an event of default
under the declaration, the rights of the holders of the trust common securities
to payment in respect of distributions and payments upon liquidation, redemption
and otherwise will be subordinated to the rights of the holders of the trust
preferred securities. Except in the limited circumstances to be described in the
amended and restated declaration, the trust common securities will also carry
the right to vote to appoint, remove or replace any of the trustees of a trust.
All of the trust common securities of each trust will be directly or indirectly
owned by us.

            DESCRIPTION OF THE TRUST PREFERRED SECURITIES GUARANTEES

     A summary of information concerning the trust guarantees which we will
execute and deliver from time to time for the benefit of the holders of the
trust preferred securities is set forth below. Each trust guarantee will be
qualified as an indenture under the Trust Indenture Act. The Chase Manhattan
Bank will act as the trust guarantee trustee, or indenture trustee, under each
trust guarantee. The terms of each trust guarantee will be those set forth in
that trust guarantee and those made part of that trust guarantee by the Trust
Indenture Act. The following is a summary of the material terms and provisions
of the trust preferred securities guarantees. You should refer to the provisions
of the form of trust guarantee and the Trust Indenture Act for a more complete
discussion. We have filed the form of trust guarantee as an exhibit to the
registration statement of which this prospectus is a part. Each trust guarantee
will be held

                                        23
   44

by the trust guarantee trustee for the benefit of the holders of the trust
preferred securities of the applicable trust.

GENERAL

     Under each trust guarantee, we will irrevocably and unconditionally agree,
to the extent set forth in each applicable trust guarantee, to pay the trust
guarantee payments described below in full to the holders of the trust preferred
securities issued by a trust, in the event they are not paid by or on behalf of
the applicable trust when due, regardless of any defense, right of set-off or
counterclaim which the trust may have or assert.

     The following payments (the trust guarantee payments) with respect to trust
preferred securities of any trust not paid by the trust when due, will be
subject to the related trust guarantee:

     - any accrued and unpaid distributions required to be paid on the trust
       preferred securities, to the extent that trust will have funds legally
       and immediately available for payment;

     - the redemption price of any trust preferred securities called for
       redemption by that trust, including all accrued and unpaid distributions
       to the date of redemption, to the extent that trust has funds available
       for payment; and

     - upon dissolution, winding-up or termination of that trust (other than in
       connection with the distribution of the assets of the trust to the
       holders of trust preferred securities or the redemption of all of the
       trust preferred securities), the lesser of:

          (a) the aggregate of the liquidation amount and all accrued and unpaid
     distributions on the trust preferred securities to the date of payment, to
     the extent that trust has funds available for payment and

          (b) the amount of assets of the trust remaining available for
     distribution to holders of its trust preferred securities in liquidation of
     the trust.

     Our obligation to make a trust guarantee payment will be satisfied by our
direct payment of the required amounts to the holders of the applicable trust
preferred securities or by causing the applicable trust to pay the required
amounts to the holders.

     Each trust guarantee will be a full and unconditional guarantee with
respect to the applicable trust preferred securities, but will not apply to any
payment of distributions when the applicable trust does not have funds "legally
and immediately" available for payment. If we do not make interest payments on
the subordinated debt securities purchased by a trust, that trust will not pay
distributions on the trust preferred securities issued by it and will not have
funds "legally and immediately" available for such payment. See "Description of
the Debt Securities -- Covenants" included in this prospectus.

     We have also agreed separately to irrevocably and unconditionally guarantee
the obligations of the trusts with respect to the trust common securities (the
trust common securities guarantees) to the same extent as the trust guarantees,
except that upon an event of default under the subordinated indenture relating
to the subordinated debt securities purchased by that trust, holders of trust
preferred securities will have priority over holders of trust common securities
with respect to distributions and payments on liquidation, redemption or
otherwise.

COVENANTS

     In each trust guarantee, we will covenant that, so long as any trust
preferred securities remain outstanding, if any event that would constitute an
event of default under the trust guarantee or the declaration of the applicable
trust occurs, then we will not declare or pay any dividend on, make any

                                        24
   45

distributions with respect to, or redeem, purchase or make any liquidation
payment with respect to, any of our capital stock, with the following
exceptions:

     - purchases or acquisitions of shares of our common stock in connection
       with our obligations under our employee benefit plans,

     - purchases or acquisitions of shares of our common stock in connection
       with our obligations under any contract or security requiring us to
       purchase shares of our common stock or,

     - the purchase of fractional interests in shares of our capital stock as a
       result of a reclassification of our capital stock or the exchange or
       conversion of one class or series of our capital stock for another class
       or series of our capital stock, or make any guarantee payments with
       respect to the foregoing.

     Additionally, we will not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities,
including guarantees, issued by us which rank equally with or junior to the
subordinated debt securities.

MODIFICATION OF THE TRUST GUARANTEES; ASSIGNMENT

     Except with respect to any changes which do not adversely affect the rights
of holders of trust preferred securities, in which case no vote will be
required, each trust guarantee may be amended only with the prior approval of
the holders of not less than a majority in liquidation amount of the outstanding
trust preferred securities of the applicable trust. The manner of obtaining this
approval of holders of the trust preferred securities will be described in an
accompanying prospectus supplement. All guarantees and agreements contained in a
trust guarantee will bind our successors, assigns, receivers, trustees and
representatives and will inure to the benefit of the holders of the trust
preferred securities of the applicable trust then outstanding.

TERMINATION

     Each trust guarantee will terminate as to the trust preferred securities of
the applicable trust upon the first to occur of:

     - full payment of the redemption price of all trust preferred securities of
       the applicable trust;

     - distribution of the assets of the trust to the holders of the trust
       preferred securities of the applicable trust; and

     - full payment of the amounts payable upon liquidation of the trust in
       accordance with the declaration of the trust.

     Each trust guarantee will continue to be effective or will be reinstated,
as the case may be, if at any time any holder of trust preferred securities
issued by the applicable trust must restore payment of any sums paid under the
trust preferred securities or the trust guarantee.

EVENTS OF DEFAULT

     An event of default under a trust guarantee will occur upon our failure to
perform any of our payment or other obligations under that trust guarantee.

     The holders of a majority in liquidation amount of the trust preferred
securities to which the trust guarantee relates have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the trust guarantee trustee in respect of the trust guarantee or to direct the
exercise of any trust or power conferred upon the trust guarantee trustee under
the trust preferred securities guarantee. If the trust guarantee trustee fails
to enforce the trust guarantee, any holder of trust preferred securities
relating to the trust guarantee may institute a legal proceeding directly
against us to enforce the trust guarantee trustee's rights under the trust
guarantee, without first instituting a legal proceeding against the

                                        25
   46

relevant trust, the trust guarantee trustee or any other person or entity.
However, if we have failed to make a guarantee payment, a holder of trust
preferred securities may directly institute a proceeding against us for
enforcement of the trust guarantee for such payment. We waive any right or
remedy to require that any action be brought first against the trust or any
other person or entity before proceeding directly against us.

STATUS OF THE TRUST GUARANTEES

     The trust guarantees will constitute our unsecured obligations and will
rank:

     - subordinate and junior in right of payment to all of our other
       liabilities, except those obligations or liabilities made equal in
       priority or subordinate by their terms;

     - equally with the most senior preferred or preference stock that we may
       issue and with any guarantee that we may enter into in respect of any
       preferred or preference stock of any our affiliates; and

     - senior to our common stock.

     The terms of the trust preferred securities provide that each holder of
trust preferred securities of the applicable trust, by acceptance of the
securities, agrees to the subordination provisions and other terms of the trust
guarantee relating to the applicable trust preferred securities.

     The trust guarantees will constitute a guarantee of payment and not of
collection. Accordingly, the guaranteed party may institute a legal proceeding
directly against the guarantor to enforce its rights under the trust guarantee
without instituting a legal proceeding against any other person or entity.

INFORMATION CONCERNING THE TRUST GUARANTEE TRUSTEE

     Prior to the occurrence of a default with respect to a trust guarantee and
after the curing or waiving of all events of default with respect to that trust
guarantee, the trust guarantee trustee undertakes to perform only those duties
as are specifically set forth in that trust guarantee. In case an event of
default has occurred and has not been cured or waived, the guarantee trustee
will exercise the same degree of care as a prudent individual would exercise in
the conduct of his or her own affairs. Subject to these provisions, the trust
guarantee trustee is under no obligation to exercise any of the powers vested in
it by a trust guarantee at the request of any holder of trust preferred
securities, unless offered reasonable indemnity against the costs, expenses and
liabilities which might be incurred through the exercise of those powers.

     We and our affiliates may, from time to time, maintain a banking
relationship with the trust guarantee trustee.

GOVERNING LAW

     The trust guarantees will be governed by, and construed in accordance with,
the laws of the State of New York.

                                        26

               RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES,
              THE SUBORDINATED DEBT SECURITIES AND THE GUARANTEES

     As long as we make payments of interest and other payments when due on the
subordinated debt securities, those payments will be sufficient to cover
distributions and other payments due on the trust preferred securities,
primarily because:

     - the aggregate principal amount of the subordinated debt securities will
       be equal to the sum of the aggregate stated liquidation preference of the
       trust securities;

     - the interest rate and interest and other payment dates of the
       subordinated debt securities will match the distribution rate and
       distribution and other payment dates for the trust preferred securities;

     - we will pay any and all costs, expenses and liabilities of the trusts,
       except the trusts' obligations to holders of its trust preferred
       securities under the terms of such trust preferred securities; and

     - the declaration of each trust prohibits the trust from engaging in any
       activity that is not consistent with the limited purposes of the trust.

     We irrevocably guarantee payments of distributions and other amounts due on
the trust preferred securities of a trust, to the extent the trust has funds
available for the payment of such distributions as described in "Description of
Trust Guarantees" in this prospectus. Taken together, our obligations under the
subordinated debt securities, the subordinated indenture, the declarations of
the trusts and the trust guarantees provide a full, irrevocable and
unconditional guarantee of payments of distributions and other amounts due on
the trust preferred securities. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such a
guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of each of
the trust's obligations under its trust preferred securities. If we do not make
payments on the subordinated debt securities, the trusts will not pay
distributions or other amounts due on the trust preferred securities. The trust
guarantees do not cover payment of distributions when the applicable trust does
not have sufficient funds to pay the distributions. In this event, the remedies
of a holder of the trust preferred securities of the trust are described in this
prospectus under "Description of the Trust Guarantees -- Events of Default." Our
obligations under the trust guarantees are unsecured and are subordinate and
junior in right of payment to all of our other liabilities.

     Notwithstanding anything to the contrary in the subordinated indenture and
to the extent set forth in the subordinated indenture, we have the right to
set-off any payment we are otherwise required to make under the subordinated
indenture with and to the extent we have made, or are concurrently on the date
of such payment making, a payment under a trust guarantee.

     A holder of trust preferred securities of a trust may institute a legal
proceeding directly against us to enforce its rights under the trust guarantee
without first instituting a legal proceeding against the trust guarantee
trustee, the trust or any other person or entity.

     The trust preferred securities of a trust evidence a beneficial interest in
the trust. The trusts exist for the sole purpose of issuing the trust securities
and investing the proceeds in subordinated debt securities. A principal
difference between the rights of a holder of trust preferred securities and a
holder of subordinated debt securities is that a holder of subordinated debt
securities is entitled to receive from us the principal amount of and interest
accrued on subordinated debt securities held, while a holder of trust preferred
securities is entitled to receive distributions from a trust, or from us under
the trust guarantee, if and to the extent the trust has funds available for the
payment of such distributions.

     Upon any voluntary or involuntary termination, winding-up or liquidation of
a trust involving the liquidation of the subordinated debt securities, the
holders of the trust preferred securities of the trust will be entitled to
receive, out of assets held by the trust and after satisfaction of liabilities
to creditors of the trust as provided by applicable law, the liquidation
distribution in cash. Upon any voluntary or involuntary liquidation or
bankruptcy of us, the property trustees of a trust, as holder of the
subordinated debt

                                        27
   48

securities of the trust, would be a subordinated creditor of us, subordinated in
right of payment to all of our senior debt, but entitled to receive payment in
full of principal and interest, before any of our stockholders receive payments
or distributions. Since we are the guarantor under the trust guarantees and we
have agreed to pay for all costs, expenses and liabilities of the trusts other
than the trusts' obligations to the holders of the trust preferred securities,
the positions of a holder of trust preferred securities and a holder of
subordinated debt securities relative to other creditors and to our shareholders
in the event of our liquidation or bankruptcy would be substantially the same.

     A default or event of default under any of our senior debt will not
constitute a default or event of default under the subordinated indenture.
However, in the event of payment defaults under, or acceleration of, our senior
debt, the subordination provisions of the subordinated indenture provide that no
payments may be made on the subordinated debt securities until our senior debt
has been paid in full or any payment default under our senior debt has been
cured or waived. Our failure to make required payments on a series of
subordinated debt securities would constitute an event of default under the
subordinated indenture.

       that the dealer will determine at the time it sells our securities.

liabilities, including liabilities under the Securities Act of 1933. Our agents,
underwriters, and dealers, or their affiliates, may be customers of, engage in
transactions with or perform services for us, in the ordinary course of
business.

     We may authorize our agents and underwriters to solicit offers by certain
institutions to purchase our securities at the public offering price under
delayed delivery contracts.

     - If we use delayed delivery contracts, we will disclose that we are using
       them in the prospectus supplement and will tell you when we will demand
       payment and delivery of the securities under the delayed delivery
       contracts.

     - These delayed delivery contracts will be subject only to the conditions
       that we set forth in the prospectus supplement.

     - We will indicate in our prospectus supplement the commission that
       underwriters and agents soliciting purchases of our securities under
       delayed delivery contracts will be entitled to receive.

     Underwriters, dealers and agents may engage in transactions with, or

obligated to do so and may discontinue any market making at any time without
notice. The securities may or may not be listed on a national securities
