                              ABOUT THE DEBENTURES

Securities Offered.........  $1,766,500,000 aggregate principal amount at
                             maturity of zero coupon convertible debentures due
                             February 28, 2021, including 8,456,621 shares of
                             common stock into which the debentures are
                             convertible. We will not pay periodic interest on
                             the debentures, except as described under
                             "Description of Debentures -- Tax Event." See
                             "Description of Debentures -- General."

Selling Security Holders...  The securities to be offered and sold using this
                             prospectus will be offered and sold by the selling
                             security holders named in this prospectus or in any
                             supplement to this prospectus. See "Selling
                             Security Holders."

Conversion.................  You have the option to convert the debentures into
                             our common stock at any time prior to maturity or
                             their earlier redemption. You can convert the
                             debentures into common stock at a fixed conversion
                             rate of 4.7872 shares per $1,000 principal amount
                             at maturity. The conversion rate will be subject to
                             adjustment if certain events occur. See
                             "Description of Debentures -- Tax Event."

                             You may exercise the option to convert only before
                             the debentures reach maturity and before we redeem
                             or repurchase them.

Original Issue Discount....  We originally issued the debentures at an original
                             issue discount for United States federal income tax
                             purposes equal to the excess of their principal
                             amount at maturity over the amount of their issue
                             price (which was $452.89 per $1,000 principal
                             amount at maturity). We will not make periodic cash
                             payments of interest on the debentures, except as
                             described under "Description of Debentures -- Tax
                             Event." Nonetheless, you should be aware that
                             accrued original issue discount will be included
                             periodically in your gross income for United States
                             federal income tax purposes. See "Material United
                             States Federal Income Tax Considerations."

                             You should be aware that you will be responsible
                             for the payment of taxes that may be due even
                             though you may not receive any cash payment at the
                             time original issue discount is included in your
                             gross income.

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

Redemption at Our Option...  We cannot redeem the debentures before February 28,
                             2006. At any time on or after February 28, 2006, we
                             can redeem all or part of the debentures for cash.
                             You can convert the debentures after they are
                             called for redemption at any time up to the
                             redemption date.

                             Redemption prices are equal to the issue price plus
                             accrued original issue discount to the date of
                             redemption. See "Description of Debentures --
                             Redemption of Debentures at Our Option."

Fundamental Change.........  You may require us to repurchase the debentures if
                             we experience a Fundamental Change. The Fundamental
                             Change purchase price is equal to the issue price
                             plus accrued original issue discount to the date of
                             repurchase, subject to adjustment in certain
                             circumstances. See "Description of
                             Debentures -- Repurchase at the Option of the
                             Holder Upon a Fundamental Change."

Repurchase at the Option of
the Holder.................  You may require us to repurchase the debentures on
                             February 28, 2006, February 28, 2011 and February
                             28, 2016 for a purchase price equal to the issue
                             price of $452.89 plus accrued original issue
                             discount to the date of repurchase. We may elect to
                             pay all or a portion of the purchase price in
                             common stock instead of cash. See "Description of
                             Debentures -- Repurchase of Debentures at the
                             Option of the Holder."

Conversion to Semiannual
  Coupon Debenture.........  If a tax event prevents us from deducting original
                             issue discount payable on the debentures, we can
                             elect to pay you interest in cash and terminate the
                             further accrual of original issue discount. See
                             "Description of Debentures -- Tax Event."

No Proceeds................  We will not receive any proceeds on the sale of the
                             securities or the conversion of the debentures.

Stock Exchange Symbol......  Our common stock is listed on the New York Stock
                             Exchange and the Pacific Exchange under the symbol
                             "EPG."

(1) Earnings were inadequate to cover fixed charges by $1 million for the year
    ended December 31, 1998, and $505 million for the quarter ended March 31,
    2001.

     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.

                                        3

     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.

                                  RISK FACTORS

     Before you invest in the Debentures and in El Paso common stock, you should
read the risks, uncertainties and factors which may adversely affect El Paso
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/A filed May 17, 2001,
which are incorporated by reference in this prospectus.

RISKS RELATED TO THE DEBENTURES

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 debentures.
Our subsidiaries are separate and distinct legal entities and have no obligation
to pay any amounts due on these debentures 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 senior indenture governing the debentures, 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 debentures. The senior 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 debentures and on the ability of such subsidiaries to make
distributions, loans, other payments or asset transfers to us. The total
long-term indebtedness of our subsidiaries as of March 31, 2001, was
approximately $8 billion on a pro forma combined basis giving effect to our
merger with Coastal.

We may not have the ability to raise the funds necessary to finance the change
in control repurchase or the repurchase at the option of the holder.

     Upon the occurrence of specific kinds of change in control events, holders
of debentures may require us to repurchase their debentures for cash. However,
it is possible that we would not have sufficient funds at that time to make the
required repurchase of debentures. In addition, some important corporate events,
such as leveraged recapitalizations, that would increase the level of our
indebtedness, would not constitute a change in control under the debentures.

                         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

                                        5
   8

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;

     - 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/A
filed May 17, 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;

                                        6
   9

     - 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.

                            SELLING SECURITY HOLDERS

     We originally sold the debentures to Credit Suisse First Boston Corporation
(CSFB) on February 28, 2001 in a private placement. CSFB has advised us that it
resold the debentures in transactions exempt from the registration requirements
of the Securities Act of 1933 to "qualified institutional buyers" (as defined in
Rule 144A under the Securities Act) in compliance with Rule 144A. These
subsequent purchasers (and their respective donees and transferees for no
consideration) may from time to time offer and sell any or all of the debentures
or the common stock issuable on conversion of the debentures pursuant to this
prospectus.

     The debentures and the common stock to be offered and sold using this
prospectus are being registered pursuant to a registration rights agreement
between us and CSFB. In that agreement, we undertook to file a registration
statement with regard to the debentures and common stock and, subject to certain
exceptions, to keep that registration statement effective for up to two years.
The registration statement to which this prospectus relates is intended to
satisfy our obligations under that agreement.

     The selling security holders named below have advised us that they
currently intend to sell the debentures and common stock set forth below
pursuant to this prospectus. Additional selling security holders may choose to
sell debentures and common stock from time to time upon notice to us. See "Plan
of Distribution."

     Before a security holder may use this prospectus in connection with an
offering of securities, this prospectus will be supplemented to include the name
and amount of debentures and common stock beneficially owned by the selling
security holder and the amount of debentures and common stock to be offered. Any
prospectus supplement will also disclose whether any selling security holder
selling in connection with that prospectus supplement has held any position,
office or other material relationship with us or any of our predecessors or
affiliates during the three years prior to the date of the prospectus
supplement.

     The following table is based solely on information provided by the selling
security holders.

                           DESCRIPTION OF DEBENTURES

     The debentures were issued under an indenture, dated as of May 10, 1999,
between El Paso and The Chase Manhattan Bank, as supplemented by the fifth
supplemental indenture dated February 28, 2001. The debentures are subject to
the terms of the indenture as so supplemented and those terms made a part of the
indenture by reference to the Trust Indenture Act of 1939, as amended. We have
summarized in this section the material terms and provisions of the indenture as
they relate to the debentures. You should read the indenture before you buy any
of these debentures. References in this section to El Paso are solely to El Paso
Corporation and not to its subsidiaries.

     The indenture does not limit the aggregate principal amount of indebtedness
which may be issued under it. The indenture also provides that senior debt
securities may be issued from time to time in one or more series. The debentures
constitute a separate series of securities under the indenture.

GENERAL

     The debentures are general unsecured obligations of El Paso and are limited
to an aggregate principal amount at maturity of $1,766,500,000. The debentures
are scheduled to mature on February 28, 2021. The debentures will rank equally
with all of our other unsecured and unsubordinated indebtedness. The debentures
were originally sold at a substantial discount to their face amount due at
maturity and therefore have original issue discount for U.S. federal income tax
purposes. Please read "Material United States Federal Income Tax
Considerations."

     There will be no periodic cash payments of interest on the debentures,
except as described under "-- Tax Event" below. The accrual of original issue
discount in the period during which a debenture remains outstanding will be
computed on a semi-annual bond equivalent basis. The accrual of original issue
discount commenced on the issue date of the debentures. Original issue discount
or, if the debentures are converted to semi-annual coupon debentures following
the occurrence of a tax event, interest on the debentures, will cease to accrue
upon conversion, repurchase or redemption under the terms and subject to the
conditions of the indenture.

     You have the option to convert your debentures into shares of our common
stock at a conversion rate of 4.7872 shares of common stock per debenture. This
is equivalent to an initial conversion price of $94.604 per share of common
stock based on the price to investors of $452.89 per debenture. The conversion
rate is subject to adjustment if specified events occur. Holders may surrender
debentures for conversion at any time prior to maturity, unless previously
redeemed or repurchased. Upon conversion, you will receive only shares of common
stock plus cash in lieu of fractional shares, if any. You will not receive any
cash payment for the accrued original issue discount to the conversion date.

INTEREST

     We do not pay cash interest on the debentures unless we elect to do so
following a Tax Event as described under "-- Tax Event" below. You should be
aware that original issue discount accruing for the period you hold the
debentures must be included in your gross income for federal income tax
purposes. Original issue discount is generally the difference between the
adjusted issue price and the $1,000 principal amount of the debenture at
maturity. See "Material United States Federal Income Tax Considerations."

REDEMPTION OF DEBENTURES AT OUR OPTION

     We may not redeem the debentures before February 28, 2006. Beginning on
February 28, 2006, we can redeem the debentures for cash in whole or in part at
any time, upon not less than 15 nor more than 60 days' notice by mail to holders
of debentures, for a price in cash equal to the sum of (1) the $452.89 original
issue price per debenture and (2) accrued original issue discount at a rate of
4.00% per annum, computed on a semi-annual bond equivalent basis. The debentures
will be redeemable in multiples of $1,000 principal amount payable at maturity.
No sinking fund is provided for the debentures.

     The table below shows redemption prices of debentures per $1,000 principal
amount at maturity, at February 28, 2006, at each following February 28 prior to
maturity and at maturity on February 28, 2021. The prices reflect the accrued
original issue discount calculated through each date. The redemption price of a
debenture redeemed between any two dates would include an additional amount
reflecting the additional original issue discount accrued since the immediately
preceding date in the table to the actual redemption date.

     From and after the date a tax event occurs and we elect to pay cash
interest at 4.00% per year on the debentures instead of accruing original issue
discount, the principal amount for redemption will be restated and will be
calculated by adding the $452.89 original issue price and the original issue
discount which had accrued until the date on which we exercise the option to
commence paying cash interest.

     If we decide to redeem fewer than all of the outstanding debentures, the
trustee will select the debentures to be redeemed by lot, on a pro rata basis or
by another method the trustee considers fair and appropriate.

     If the trustee selects a portion of your debentures for partial redemption
and you convert a portion of the same debentures, the converted portion will be
deemed to be from the portion selected for redemption. Debentures registered in
the name of DTC or its nominee will be redeemed as described under the caption
entitled "-- Book-Entry System."

CONVERSION OF DEBENTURES BY HOLDERS

     You have the right to convert each debenture into 4.7872 shares of common
stock so long as the conditions described below are met. You may convert a
debenture into shares of common stock at any time until the close of business on
the last business day prior to February 28, 2021. If a debenture has been called
for redemption, you will be entitled to convert the debenture until the close of
business on the business day immediately preceding the date of redemption,
unless we default in the payment of the redemption price. If you have delivered
a repurchase notice exercising your option to require us to repurchase your
debenture, you may not convert the debenture unless you withdraw the notice in
accordance with the terms of the indenture. Similarly, if you exercise your
option to require us to repurchase your debenture upon a change in control (as
described under "Change in Control" below), that debenture may be converted only
if you withdraw your election to exercise your option in accordance with the
terms of the indenture. You may convert your debentures in part so long as you
elect to convert debentures with an integral multiple of $1,000 principal amount
at maturity.

                                        11
   14

     The initial conversion rate is 4.7872 shares of our common stock for each
$1,000 principal amount at maturity of debentures. This is equivalent to an
initial conversion price of $94.604 per share of our common stock based on the
original issue price per debenture. You will not receive any cash payment
representing accrued original issue discount upon conversion of a debenture.
Instead, upon conversion we will deliver to you a fixed number of shares of our
common stock and a cash payment to account for fractional shares, if any. The
cash payment for fractional shares will be based on the closing price of our
common stock on the trading day immediately prior to the conversion date.
Delivery of shares of our common stock will be deemed to satisfy our obligation
to pay the principal amount of the debenture, including accrued original issue
discount. Accrued original issue discount will be deemed paid in full rather
than canceled, extinguished or forfeited. We will not adjust the conversion
ratio to account for the accrued original issue discount.

     The conversion rate will be subject to adjustment upon the following
events:

     - issuance of shares of our common stock as a dividend or distribution on
       our outstanding common stock;

     - any specified subdivision, combination or reclassification of the
       outstanding common stock;

     - issuance to all stockholders of rights or warrants that allow the holders
       to purchase shares of our common stock at less than the current market
       price; provided that no adjustment will be made if holders of the
       debentures may participate in such issuance on a basis and with notice
       that our board of directors determines to be fair and appropriate or in
       some other cases;

     - distribution to all stockholders of debt or other assets but excluding
       distributions of rights and warrants described above and all-cash
       distributions; provided that no adjustment will be made if holders of the
       debentures may participate in such distribution;

     - the distribution to all or substantially all stockholders of all-cash
       distributions in an aggregate amount that, together with (1) any cash and
       the fair market value of any other consideration payable in respect of
       any tender offer by us or any of our subsidiaries for shares of our
       common stock consummated within the preceding 12 months not triggering a
       conversion price adjustment and (2) all other all-cash distributions to
       all or substantially all stockholders made within the preceding 12 months
       not triggering a conversion price adjustment, exceeds an amount equal to
       12.5% of the market capitalization of our common stock on the business
       day immediately preceding the day on which we declare the distribution,
       provided that no adjustment will be made if holders of the debentures may
       participate in such distribution; and

     - the purchase of shares of our common stock pursuant to a tender offer
       made by us or any of our subsidiaries to the extent that the same
       involves aggregate consideration that, together with (1) any cash and the
       fair market value of any other consideration payable in respect of any
       tender offer by us or any of our subsidiaries for shares of our common
       stock consummated within the preceding 12 months not triggering a
       conversion price adjustment and (2) all-cash distributions to all or
       substantially all stockholders made within the preceding 12 months not
       triggering a conversion price adjustment, exceeds an amount equal to
       12.5% of the market capitalization of our common stock on the expiration
       date of the tender offer.

     Each share of common stock issued upon conversion of a debenture will
include a right issued under our existing shareholder rights agreement. If our
existing shareholder rights agreement expires or is terminated and, while the
debentures are outstanding, we implement another shareholder rights plan, such
plan will provide that in lieu of making an adjustment of the conversion rate,
each share of our common stock issued upon conversion of the debentures at any
time will include a preferred stock purchase right

                                        12
   15

(notwithstanding the occurrence of an event causing such rights to separate from
our common stock prior to conversion). As a result, there will not be any
adjustment to the conversion rate as a result of:

     - the distribution of separate certificates representing the rights;

     - the exercise or redemption of the rights in accordance with the
       shareholder rights agreement; or

     - the termination or invalidation of the rights.

     We may from time to time increase the conversion rate to the extent
permitted by law by any amount for any period if the period is at least 20 days
or such longer period as may be required by law, so long as the increase is
irrevocable during the period. Subsequent to such increase, we may from time to
time lower the conversion rate to any rate that is not lower than the conversion
rate that would have been applicable had such increase not been made, if we
determine that the decrease would be in our best interests. For purposes of this
paragraph, a determination by our board of directors will be conclusive. If we
increase or decrease the conversion rate, we will give at least seven days'
notice of the increase. We may, at our option, make increases in the conversion
rate, in addition to those described above, as we deem advisable to avoid or
diminish any income tax to holders of common stock resulting from any dividend
or distribution of stock, or rights to acquire stock, or from any event treated
as a dividend distribution or a right to acquire stock for income tax purposes.
See "Material United States Federal Income Tax Considerations."

     No adjustment in the conversion rate will be required unless the adjustment
would require a change of at least 1% in the rate then in effect; provided that
any adjustment that would otherwise be required to be made will be carried
forward and taken into account in any subsequent adjustment.

     Except as stated above, the conversion rate will not be adjusted for the
issuance of common stock or any securities convertible into or exchangeable for
common stock or carrying the right to purchase any of the foregoing.

     If we exercise our option to pay interest in cash in lieu of accruing
original issue discount on a debenture following a tax event, the holder will be
entitled on conversion to receive the same number of shares of common stock that
the holder would have received if we had not exercised our option. If we
exercise our option, debentures surrendered for conversion during the period
from the close of business on the record date next preceding the next interest
payment date to the opening of business on the next interest payment date
(except debentures to be redeemed on the next interest payment date) must also
be accompanied by an amount equal to the accrued and unpaid interest on the
debenture that the registered holder is to receive in cash. Except where
debentures surrendered for conversion must be accompanied by the payment
described in this paragraph, no interest on converted debentures will be payable
by us on any interest payment date subsequent to the date of conversion. See
"-- Tax Event."

     In the case of either: (1) any reclassification of the common stock, or (2)
a consolidation or merger involving El Paso or a conveyance, transfer or lease
to another entity of the property and assets of El Paso substantially as an
entirety, if holders of our common stock would be entitled to receive any form
of consideration with respect to or in exchange for common stock, the holders of
the debentures then outstanding would be entitled to convert their debentures
into the kind and amount of consideration which they would have owned or been
entitled to receive had their debentures been converted immediately prior to the
applicable transaction. This assumes that a holder of debentures would not have
exercised any rights of election as to the consideration receivable in
connection with the transaction.

     In the event of a taxable distribution to holders of common stock or in
certain other circumstances requiring an adjustment to the conversion rate, the
holders of debentures may, in certain circumstances, be deemed to have received
a distribution subject to United States income tax as a dividend. In certain
other circumstances, the absence of an adjustment may result in a taxable
dividend to the holders of common stock. See "Material United States Federal
Income Tax Considerations."

REPURCHASE OF DEBENTURES AT THE OPTION OF THE HOLDER

     You have the right to require us to repurchase the debentures on February
28, 2006, February 28, 2011 and February 28, 2016. We will be required to
repurchase any outstanding debenture for which you deliver a written repurchase
notice to the paying agent. This notice must be delivered during the period
beginning at any time from the opening of business on the date that is 20
business days prior to the relevant repurchase date until the close of business
on the business day next preceding the repurchase date. If the repurchase notice
is given and withdrawn during the period, we will not be obligated to repurchase
the debenture(s) for which the withdrawn notice was given. Our repurchase
obligation will be subject to some additional conditions. Also, our ability to
satisfy our repurchase obligations may be affected by the factors described in
"Risk Factors" under the caption "We May Not Have the Ability to Raise the Funds
Necessary to Finance the Change in Control Repurchase or the Repurchase at the
Option of the Holder."

     The purchase price payable in respect of a debenture will be equal to the
$452.89 original issue price plus accrued original issue discount to the
repurchase date. The repurchase prices of a debenture as of each of the
repurchase dates will be:



REPURCHASE DATE                                               REPURCHASE PRICE
- ---------------                                               ----------------
                                                           
February 28, 2006...........................................      $552.07
February 28, 2011...........................................      $672.97
February 28, 2016...........................................      $820.35


     We will have the option to pay the purchase price, in whole or in part, in
our common stock, in cash or in a combination of cash and shares of our common
stock. For a discussion of the tax treatment of a holder receiving cash, shares
of our common stock or any combination thereof, please read "Material United
States Federal Income Tax Considerations." If we elect to pay the purchase
price, in whole or in part, in shares of our common stock, the number of shares
to be delivered by us in respect of the portion of the purchase price to be paid
in common stock will be equal to that portion of the purchase price divided by
the market price of one share of our common stock, such market price to be
determined as provided below. However, no fractional shares of our common stock
will be delivered upon any repurchase by El Paso of debentures. Instead, we will
pay cash based on the market price for all fractional shares.

     If following a tax event, we have previously exercised our option to pay
cash interest instead of accruing original issue discount on the debentures, the
repurchase price will be equal to the restated principal amount plus the accrued
and unpaid interest that accrued on the debenture from the date we exercise our
option through the repurchase date. See "-- Tax Event."

     If we choose to pay the repurchase price in whole or in part in shares of
our common stock or a combination of cash and shares of our common stock, we
will be required to give notice on a date not less than 20 business days prior
to each repurchase date to all holders at their addresses shown in the register
of the registrar, and to beneficial owners as required by applicable law (that
is, if the notice contemplated in this paragraph is not given, we will pay the
repurchase price with cash), stating among other things:

     - whether we will pay the purchase price of the debentures in cash, in
       shares of our common stock, or any combination thereof, specifying the
       percentages of each;

     - if we elect to pay all or part of the purchase price in shares of our
       common stock, the method of calculating the market price of our common
       stock; and

     - the procedures that holders must follow to require us to repurchase their
       debentures.

                                        14
   17

     Your notice electing to require us to repurchase your debentures must
state:

     - if certificated debentures have been issued, the debenture certificate
       numbers, or if not certificated, your notice must comply with appropriate
       DTC procedures;

     - the portion of the principal amount at maturity of debentures to be
       repurchased, in integral multiples of $1,000;

     - that the debentures are to be repurchased by us pursuant to the
       applicable provisions of the indenture and the debentures; and

     - if we elect, pursuant to the notice that we are required to give, to pay
       the purchase price in shares of our common stock, in whole or in part,
       but the purchase price is ultimately to be paid to the holder entirely in
       cash because any of the conditions to payment of the purchase price or
       portion of the purchase price in shares of our common stock is not
       satisfied prior to the close of business on the third business day prior
       to the repurchase date, as described below, whether the holder elects:

          (1) to withdraw the repurchase notice as to some or all of the
     debentures to which it relates, or

          (2) to receive cash in respect of the entire repurchase price for all
     debentures or portions of debentures subject to the repurchase notice.

     If the holder fails to indicate the holder's choice with respect to the
election described in the final bullet point above, the holder will be deemed to
have elected to receive cash in respect of the entire repurchase price for all
debentures subject to the repurchase notice in these circumstances. For a
discussion of the tax treatment of a holder receiving cash instead of shares of
common stock, see "Material United States Federal Income Tax Considerations."

     You may withdraw any repurchase notice by a written notice of withdrawal
delivered to the paying agent prior to the close of business on the business day
next preceding the repurchase date. The notice of withdrawal must state:

     - the principal amount at maturity of the withdrawn debenture(s);

     - if certificated debentures have been issued, the certificate numbers of
       the withdrawn debentures, or if not certificated, your notice must comply
       with appropriate DTC procedures; and

     - the principal amount at maturity, if any, which remains subject to the
       repurchase notice.

     For purposes of any repurchase to be made as described herein with shares
of our common stock, the term "market price" means the average of the sale
prices of our common stock for the five trading day period ending on the third
business day prior to the applicable repurchase date (if the third business day
prior to the applicable repurchase date is a trading day, or if not, then on the
last trading day immediately preceding the third business day), appropriately
adjusted to take into account the occurrence, during the period commencing on
the first of the trading days during the five trading day period and ending on
the repurchase date, of some events that would result in an adjustment of the
conversion rate with respect to our common stock.

     The "sale price" of our common stock on any date means the reported closing
sale price per share of our common stock (or if no closing sale price is
reported, the average of the bid and ask prices or, if there is more than one
bid or ask price, the average of the average bid and the average ask prices) on
the date as reported in composite transactions for the principal United States
securities exchange on which the common stock is traded or, if the common stock
is not traded on a United States national or regional securities exchange, as
reported by the Nasdaq System.

     Because the market price of the common stock is determined prior to the
applicable repurchase date, holders of debentures bear the market risk with
respect to the value of the common stock to be received from the date the market
price is determined to the repurchase date. We may pay the purchase price or

                                        15
   18

any portion of the purchase price in shares of our common stock only if the
information necessary to calculate the market price is published in a daily
newspaper of national circulation.

     Upon determination of the actual number of shares of our common stock to be
paid upon redemption of the debentures, we will issue a press release containing
this information or publish the information on our Web site on the World Wide
Web or through such other public medium as we may use at that time.

     El Paso's right to repurchase debentures with common stock is subject to
the satisfaction of various conditions, including:

     - the registration of the common stock under the Securities Act, if
       required, and

     - compliance with other applicable federal and state securities laws, if
       any.

     If the conditions are not satisfied by a repurchase date, El Paso will pay
the purchase price of the debentures to be purchased on the repurchase date
entirely in cash. El Paso will comply with the provisions of Rule 13e-4 and any
other tender offer rules under the Securities Exchange Act which may then be
applicable. In connection with any offer by us to repurchase debentures at the
option of holders, we will file Schedule TO or any other schedule required.

     A holder must either effect book-entry transfer or deliver the debenture,
together with necessary endorsements, to the office of the paying agent after
delivery of the repurchase notice to receive payment of the repurchase price.
You will receive payment promptly following the later of the repurchase date and
the time of book-entry transfer or the delivery of the debenture. If the paying
agent holds money or securities sufficient to pay the purchase price of the
debenture on the business day following the purchase date, then on and after
such date:

     - the debenture will cease to be outstanding;

     - original issue discount (or, if the debentures have been converted to
       interest-bearing debentures following a tax event, interest) will cease
       to accrue; and

     - all other rights of the holder will terminate.

This will be the case whether or not book-entry transfer of the debenture is
made or whether or not the debenture is delivered to the paying agent, and all
other rights of the holder will terminate, other than the right to receive the
purchase price upon book-entry transfer or delivery of the debenture.

     No debentures may be repurchased at the option of the holder for cash if
there has occurred, prior to, on or after the giving by the holders of the
debentures of the required repurchase notice, and is continuing an event of
default described under "-- Events of Default; Notice and Waiver" below, other
than a default in the payment of the purchase price with respect to the
debentures.

RANKING

     The debentures constitute senior debt of El Paso and rank equally with all
of our unsecured and unsubordinated debt and will rank senior to any future
subordinated indebtedness.

     El Paso is a holding company that conducts all of its operations
exclusively through its subsidiaries. Our only significant assets are the
capital stock of our subsidiaries, and our subsidiaries generate substantially
all of our operating income and cash flow. As a result, dividends or advances
from our subsidiaries are the principal source of funds necessary to meet our
debt service obligations. Contractual provisions or laws, as well as our
subsidiaries' financial condition and operating requirements, may limit our
ability to obtain cash from our subsidiaries that we require to pay our debt
service obligations, including payments on the debentures. In addition, holders
of the debentures have a junior position to the claims of creditors of our
subsidiaries on their assets and earnings.

                                        16
   19

TAX EVENT

     We have the option to elect to pay cash interest on the debentures from and
after the date a tax event (as defined below) occurs instead of accruing
original issue discount. The principal amount, which will be restated if we
exercise this option, will be calculated by adding the $452.89 original issue
price per debenture and the original issue discount which had accrued up until
the date on which we exercise this option. This restated principal amount will
be the amount due at maturity (instead of $1,000). If we elect this option,
interest will be based on a 360-day year comprised of twelve 30-day months.
Interest will accrue from the option exercise date and will be payable
semi-annually on February 28 and August 28.

     A tax event occurs when we receive an opinion from an experienced
independent tax counsel stating that, as a result of either:

     - any amendment, change or announced prospective change in the laws or
       regulations of the United States or any of its political subdivisions or
       taxing authorities of the United States; or

     - any amendment, change, interpretation or application of the laws or
       regulations by any legislative body, court, government agency or
       regulatory authority,

there is more than an insubstantial risk that interest, including original issue
discount, payable on the debentures either

     - would not be deductible on a current accrual basis; or

     - would not be deductible under any other method,

in whole or in part, by us for United States federal income tax purposes.

CHANGE IN CONTROL

     If we undergo a change in control, you will have the option to require us
to purchase your debentures 35 business days after the change in control. If you
exercise this option, we will pay you a purchase price equal to the $452.89
original issue price per debenture plus accrued original issue discount thereon
through the purchase date or, if we have elected to pay cash interest on the
debentures following a tax event, the restated principal amount plus accrued and
unpaid interest through the purchase date. You may require us to purchase all or
any part of the debentures so long as the principal amount at maturity of the
debentures being purchased is a multiple of $1,000.

     A change in control will occur in the following situations:

     - any person or group (other than El Paso or any of its subsidiaries) after
       the first issuance of debentures becomes the beneficial owner of our
       voting stock representing more than 50% of the total voting power of all
       of our classes of voting stock entitled to vote generally in the election
       of the members of our board of directors; or

     - we consolidate with or merge into another person (other than a
       subsidiary), we sell, convey, transfer or lease our properties and assets
       substantially as an entirety to a person (other than a subsidiary), or
       any person (other than a subsidiary) consolidates with or merges with or
       into our company, and our outstanding common stock is reclassified into,
       exchanged for or converted into the right to receive any other property
       or security, provided that none of these circumstances will constitute a
       change in control if, after a transaction, the persons that beneficially
       owned our voting stock immediately prior to the transaction beneficially
       own, in substantially the same proportion, shares with a majority of the
       total voting power of all outstanding voting securities of the surviving
       or transferee person that are entitled to vote generally in the election
       of that person's board of directors;

unless, in each case, at least 50% of the consideration, other than cash
payments for fractional shares, in the transaction or transactions constituting
the change in control, consists of shares of voting common
                                        17
   20

stock of the person that are, or upon issuance will be, traded on a national
securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States.

     You must deliver a written notice to the paying agent prior to the close of
business on the business day prior to the date on which the debentures are to be
repurchased to exercise the repurchase right upon a change in control. This
notice must specify the debentures submitted for repurchase. You may withdraw
the notice by delivering a written notice of withdrawal to the paying agent
before the same date.

     Within 15 business days after a change in control, we will publish and mail
to the trustee and to each holder of the debentures a written notice of the
change in control which specifies the terms and conditions and the procedures
required for exercise of a holder's right to require us to purchase its
debentures.

     If a change in control were to occur, we may not have enough funds to pay
the change in control repurchase price. In addition, we have, and may in the
future incur, other indebtedness with similar change in control provisions
permitting its holders to accelerate or to require us to repurchase our
indebtedness upon the occurrence of similar events or on some specified dates.
If we fail to repurchase the debentures when required following a change in
control, we will be in default under the indenture whether or not repurchase is
permitted by the related subordination provisions.

MERGER AND SALES OF ASSETS BY EL PASO

     The indenture generally permits a consolidation or merger by El Paso with
another entity or a sale by us of all or substantially all of our assets as an
entirety. We have agreed, however, that we will not consolidate with or merge
with or into any other person or convey or transfer or lease our properties and
assets substantially as an entirety to another person, unless among other items:

     - we are the continuing corporation or, if we are not the continuing
       corporation, the resulting, surviving or transferee person is a
       corporation or partnership organized under the laws of the United States
       or any state thereof or the District of Columbia;

     - the successor or transferee entity, if other than us, expressly assumes
       by a supplemental indenture executed and delivered to the trustee, in
       form satisfactory to the trustee, the due and punctual payment of the
       principal of, any premium on and any interest on, all the outstanding
       debentures and the performance of every covenant in the indenture to be
       performed or observed by us and provides for conversion rights in
       accordance with applicable provisions of the indenture;

     - immediately after giving effect to the transaction, no event of default
       (as defined in the indenture) exists; and

     - we have delivered to the trustee an officers' certificate and an opinion
       of counsel, each stating that such consolidation, merger, conveyance or
       transfer and such supplemental indenture comply with the foregoing
       provisions relating to such transaction.

     In case of any such consolidation, merger, conveyance or transfer, the
successor entity will succeed to and be substituted for us as obligor on the
debentures, with the same effect as if it had been named in the indenture as our
company.

COVENANTS

     The indenture contains covenants that are applicable (unless waived or
amended) so long as any debentures remain outstanding.

     LIMITATION ON LIENS.  The 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
indenture or thereafter acquired, to secure any debt of El Paso or any other
person (other than the debt securities issued under the indenture), without
causing all of the debt securities outstanding under the indenture to be secured
equally and ratably with, or prior to, the new debt

                                        18
   21

so long as the new debt is so secured. This restriction does not, however,
prohibit us from creating the following:

     - Any lien upon any property or assets of El Paso or any restricted
       subsidiary in existence on the date the debentures are issued or created
       pursuant to an "after-acquired property" clause or similar term in
       existence on the date the debentures are issued or any mortgage, pledge
       agreement, security agreement or other similar instrument in existence on
       the date the debentures are issued;

     - Any lien upon any property or assets created at the time of acquisition
       of such property or assets by El Paso or any restricted subsidiary 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;

     - Any lien upon any property or assets existing thereon at the time of the
       acquisition thereof by us or any restricted subsidiary (whether or not
       the obligations secured thereby are assumed by us or any restricted
       subsidiary);

     - Any lien upon any property or assets of a person existing thereon at the
       time such person becomes a restricted subsidiary by acquisition, merger
       or otherwise;

     - The assumption by us or any restricted subsidiary of obligations secured
       by any lien existing at the time of the acquisition by us or any
       restricted subsidiary of the property or assets subject to such lien or
       at the time of the acquisition of the person which owns such property or
       assets;

     - Any lien on property to secure all or part of the cost of construction or
       improvements thereon 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;

     - 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;

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

     - Any lien in favor of El Paso or any restricted subsidiary;

     - Any lien created or assumed by El Paso or any restricted subsidiary 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 El Paso or any
       subsidiary;

     - Any lien upon property or assets of any foreign restricted subsidiary to
       secure debt of that foreign restricted subsidiary;

     - Permitted liens (as defined below);

     - 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 any
       of the 12 bullet points above; or

                                        19
   22

     - 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 the 13 bullet
       points above, or of any debt secured thereby; provided, however, that the
       principal amount of debt secured thereby 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, 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 limitation on liens, under the indenture, we
may, and we may permit any restricted subsidiary to, create, assume, incur, or
suffer to exist any lien upon any principal property to secure debt of El Paso
or any person (other than debt securities issued under the indenture) that is
not excepted by the 14 bullet points in the preceding paragraph without securing
the debt securities issued under the 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 the four bullet
points of the first paragraph of the restriction on sale-leasebacks covenant
described below) does not exceed 15% of consolidated net tangible assets.

     LIMITATION ON SALE AND LEASE-BACK TRANSACTIONS.  The indenture also
provides that we will not, nor will we permit any restricted subsidiary to
engage in a sale-leaseback transaction, unless:

     - 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;

     - the sale-leaseback transaction involves a lease for a period, including
       renewals, of not more than three years;

     - El Paso or such restricted subsidiary 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 debt securities; or

     - El Paso or such restricted subsidiary, 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 El Paso or any such restricted subsidiary, or (B) investment in
       another principal property.

     Notwithstanding the limitation on liens described in the immediately
preceding paragraph, under the indenture we may, and we may permit any
restricted subsidiary to, effect any sale-leaseback transaction that is not
excepted by any 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 the 14 bullet points of the first paragraph
of the limitation on liens covenant described above, do not exceed 15% of the
consolidated net tangible assets.

                                        21
   24

          "PERSON" means any individual, corporation, partnership, joint
     venture, limited liability company, association, joint-stock company,
     trust, other entity, unincorporated organization, or government or any
     agency or political subdivision thereof.

          "PRINCIPAL PROPERTY" means (1) any pipeline assets of El Paso or any
     subsidiary, including any related facilities employed in the
     transportation, distribution or marketing of natural gas, that are located
     in the United States or Canada, and (2) any processing or manufacturing
     plant owned or leased by El Paso or any subsidiary that is located within
     the United States or Canada, except, in the case of either clause (1) or
     (2), any such assets or plant which, in the opinion of El Paso's board of
     directors, is not material in relation to the activities of El Paso and its
     subsidiaries as a whole.

          "RESTRICTED SUBSIDIARY" means any subsidiary of El Paso owning or
     leasing any principal property.

          "SALE-LEASEBACK TRANSACTION" means the sale or transfer by El Paso or
     any restricted subsidiary of any principal property to a person (other than
     El Paso or a subsidiary) and the taking back by El Paso or any restricted
     subsidiary, as the case may be, of a lease of such principal property.

EVENTS OF DEFAULT

     The following are events of default with respect to the debentures:

     - default for 30 days in the payment of any interest on the debentures
       (after any election by us to pay cash interest on the debentures
       following a tax event) or in the payment of any additional interest due
       under the registration rights agreement;

     - default in payment of the principal of or any premium on the debentures
       at maturity (or, if we have elected to pay cash interest on the
       debentures following a tax event, the restated principal amount),
       original issue price, accrued original issue discount, redemption price,
       repurchase price or change in control price, when the same becomes due
       and payable;

     - our failure to comply with any of our covenants or agreements in the
       debentures or in the indenture (other than an agreement or covenant that
       we have included in the indenture solely for the benefit of other series
       of debt securities) for 60 days after written notice by the trustee or by
       the holders of at least 25% in principal amount of all outstanding debt
       securities affected by that failure;

     - specified events involving bankruptcy, insolvency or reorganization of El
       Paso.

     The trustee may withhold notice to the holders of the debentures of any
default or event of default (except in any payment on the debentures) if the
trustee considers it in the interest of the holders of the debentures to do so.

     If an event of default for the debentures occurs and is continuing, the
trustee or the holders of at least 25% in principal amount of the debentures
(or, in some cases, 25% in principal amount of all debt securities under the
senior indenture affected, voting as one class) may declare the original issue
price plus accrued original issue discount on the debentures to be due and
payable immediately. If this happens, subject to certain conditions, the holders
of a majority in principal amount of the outstanding debentures can void the
declaration. If we exercise our option to pay interest instead of accruing
original issue discount on the debentures following a tax event, the declaration
of acceleration referred to above will make the restated principal amount plus
accrued and unpaid interest immediately payable.

     Other than its duties in case of a default, the trustee is not obligated to
exercise any of its rights or powers under the 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 the debentures 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 the debentures.

                                        22
   25

     No holder of any debentures may institute any action, or pursue any remedy
under the indenture, unless:

     - such holder gives the trustee written notice of a continuing event of
       default for the debentures;

     - the holders of not less than 25% in principal amount of the outstanding
       debentures make a written request to the trustee to pursue the remedy;

     - such holder or holders have offered to the trustee indemnity reasonably
       satisfactory to the trustee;

     - the trustee has failed to institute an action for a period of 60 days
       after receipt of notice and offer of indemnity; and

     - during that 60-day period, the holders of a majority in principal amount
       of the debentures do not give the trustee a direction inconsistent with
       the request.

     This provision does not, however, affect the right of a holder of
debentures to sue for enforcement of any overdue payment.

     In most cases, holders of a majority in principal amount of the outstanding
debentures (or of all debt securities affected, voting as one class) may direct
the time, method and place of

     - conducting any proceeding for any remedy available to the trustee; and

     - exercising any trust or power conferred on the trustee not relating to or
       arising under an event of default.

     The indenture requires us to file with the trustee each year a written
statement as to our compliance with the covenants contained in the indenture.

MODIFICATION AND WAIVER

     We may amend or supplement the indenture if the holders of a majority in
principal amount of the outstanding debt securities of all series affected by
the amendment or supplement (acting as one class) consent to it. Without the
consent of the holder of each debenture, however, no modification may:

     - change the stated maturity of the principal of, or any installment of
       principal of or interest, if any, on, any security, or reduce the
       principal amount thereof or premium, if any, on or the rate of interest
       thereon;

     - reduce the percentage in principal amount of the outstanding securities
       of any series, the consent of whose holders is required for any such
       supplemental indenture, or the consent of whose holders is required for
       any waiver provided for in the indenture;

     - change any of our obligations with respect to outstanding securities of a
       series, to maintain an office or agency in the places and for the
       purposes specified in the indenture for such series;

     - subject to specific limitations, modify specified provisions of the
       indenture except to increase the percentage of holders of a series
       required to take action under that provision or to provide that certain
       other provisions of the indenture cannot be modified or waived without
       the consent of the holder of each outstanding security affected thereby;
       or

     - adversely affect the conversion or repurchase provisions of the
       debentures.

     We may amend or supplement the indenture or waive any provision of it
without the consent of any holders of debentures in some circumstances,
including:

     - to secure the debentures pursuant to the requirements of the indenture or
       otherwise;

     - to evidence the succession of another person to El Paso and the
       assumption by any such successor of our covenants in the indenture and in
       the debentures;
                                        23
   26

     - to add to our covenants or the events of default for the benefit of the
       holders of all or any series of our securities (and if such covenants or
       events of default are to be for the benefit of less than all series of
       securities, stating that such covenants or events of default, as the case
       may be, are expressly being included solely for the benefit of such
       series) or to surrender any right or power herein conferred upon us;

     - to add to, change or eliminate any of the provisions of the indenture in
       respect of one or more series of our securities; provided, however, that
       any such addition, change or elimination will become effective only when
       there is no security outstanding of any series created prior to the
       execution of such supplemental indenture which is entitled to the benefit
       of such provision;

     - to establish the form or terms of securities of any series as permitted
       by the indenture;

     - to cure any ambiguity, to correct or supplement any provision herein
       which may be inconsistent with any other provision herein, to comply with
       any applicable mandatory provisions of law or to make any other
       provisions with respect to matters or questions arising under the
       indenture, provided that such action shall not adversely affect the
       interests of the holders of securities of any series in any material
       respect;

     - to evidence and provide for the acceptance of appointment of a successor
       trustee with respect to the securities of one or more series and to add
       to or change any of the provisions of the indenture as necessary to
       provide for or facilitate the administration of the trusts thereunder by
       more than one trustee; or

     - to modify, eliminate or add to the provisions of the indenture to the
       extent necessary to effect the qualification of the indenture under the
       Trust Indenture Act or under any similar federal statute subsequently
       enacted, and such other provisions as may be required under the Trust
       Indenture Act.

     The holders of a majority in principal amount of the outstanding debentures
(or of all debt securities affected, voting as one class) may waive any existing
or past default or event of default with respect to those debt securities. Those
holders may not, however, waive any default or event of default in any payment
on any debenture or compliance with a provision that cannot be amended or
supplemented without the consent of each holder affected.

DEFEASANCE

     When we use the term defeasance, we mean discharge from some or all of our
obligations under the indenture. If we deposit with the trustee funds or
government securities sufficient to make payments on the debentures on the dates
those payments are due and payable, then, at our option, either of the following
will occur:

     - we will be discharged from our obligations with respect to the debentures
       ("legal defeasance"); or

     - the related events of default will no longer apply to us ("covenant
       defeasance").

     If we defease the debentures, the holders of the debentures will not be
entitled to the benefits of the senior indenture, except for our obligations to
register the transfer or exchange of debentures, replace stolen, lost or
mutilated debentures or maintain paying agencies and hold moneys for payment in
trust. In the case of covenant defeasance, our obligation to pay principal,
premium and interest on the debentures will also survive.

     We will be required to deliver to the trustee an opinion of counsel that
the deposit and related defeasance would not cause the holders of the debentures
to recognize income, gain or loss for federal income tax purposes. If we elect
legal defeasance, that opinion of counsel must be based upon a ruling from the
United States Internal Revenue Service or a change in law to that effect.

                                        24
   27

GOVERNING LAW

     The senior indenture and the debentures are governed by, and construed in
accordance with, the law of the State of New York, without regard to conflicts
of laws principles.

TRUSTEE

     The Chase Manhattan Bank is the trustee, registrar, conversion agent and
paying agent in respect of the debentures.

     If an event of default occurs and is continuing, the trustee will be
required to use the degree of care and skill of a prudent man in the conduct of
his own affairs. The trustee will become obligated to exercise any of its powers
under the senior indenture at the request of any of the holders of any
debentures only after those holders have offered the trustee indemnity
reasonably satisfactory to it.

     If the trustee becomes one of our creditors, it will be subject to
limitations in the senior indenture on its rights to obtain payment of claims or
to realize on some property received for any such claim, as security or
otherwise. The trustee is permitted to engage in other transactions with us. If,
however, it acquires any conflicting interest, it must eliminate that conflict
or resign.

FORM, EXCHANGE, REGISTRATION AND TRANSFER

     We issued the debentures in registered form, without interest coupons. We
will not charge a service charge for any registration of transfer or exchange of
the debentures. We may, however, require the payment of any tax or other
governmental charge payable for that registration.

     Debentures will be exchangeable for other debentures, for the same total
principal amount and for the same terms but in different authorized
denominations in accordance with the indenture. Holders may present debentures
for registration of transfer at the office of the security registrar or any
transfer agent we designate. The security registrar or transfer agent will
effect the transfer or exchange when it is satisfied with the documents of title
and identity of the person making the request.

     We have appointed the trustee as security registrar for the debentures. We
may at any time rescind that designation or approve a change in the location
through which any registrar acts. We are required to maintain an office or
agency for transfers and exchanges in each place of payment. We may at any time
designate additional registrars for the debentures.

     In the case of any redemption, the security registrar will not be required
to register the transfer or exchange of any debenture either:

     - during a period beginning 15 business days prior to the mailing of the
       relevant notice of redemption and ending on the close of business on the
       day of mailing of the notice, or

     - if the debentures have been called for redemption in whole or in part,
       except the unredeemed portion of any debenture being redeemed in part.

PAYMENT AND PAYING AGENTS

     Payments on the debentures will be made in U.S. dollars at the office of
the trustee. At our option, however, we may make payments by check mailed to the
holder's registered address or, with respect to global debentures, by wire
transfer. We will make interest payments to the person in whose name the
debenture is registered at the close of business on the record date for the
interest payment.

     The Chase Manhattan Bank is designated as our paying agent for payments on
debentures. We may at any time designate additional paying agents or rescind the
designation of any paying agent or approve a change in the office through which
any paying agent acts.

     Subject to the requirements of any applicable abandoned property laws, the
trustee and paying agent shall pay to us upon written request any money held by
them for payments on the debentures that remain

                                        25
   28

unclaimed for two years after the date upon which that payment has become due.
After payment to us, holders entitled to the money must look to us for payment.
In that case, all liability of the trustee or paying agent with respect to that
money will cease.

BOOK-ENTRY SYSTEM

     The debentures are represented by several Global Securities (each a "Global
Security"). Each Global Security has been deposited with, or on behalf of, DTC
and is registered in the name of a nominee of DTC. Except under circumstances
described below, the debentures will not be issued in definitive form.

     DTC will credit on its book-entry registration and transfer system the
accounts of persons holding beneficial interest in the Global Security with the
respective principal amounts of the debentures represented by the Global
Security. Ownership of beneficial interests in a Global Security will be limited
to persons that have accounts with DTC or its nominee ("participants") or
persons that may hold interests through participants. Ownership of beneficial
interests in a Global Security will be shown on, and the transfer of that
ownership will be effected only through, records maintained by DTC or its
nominee (with respect to interests of persons other than participants). The laws
of some states require that some purchasers of securities take physical delivery
of the securities in definitive form. Such limits and such laws may impair the
ability to transfer beneficial interests in a Global Security.

     So long as DTC or its nominee is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
holder of the debentures represented by that Global Security for all purposes
under the indenture. Except as provided below, owners of beneficial interests in
a Global Security will not be entitled to have debentures represented by that
Global Security registered in their names, will not receive or be entitled to
receive physical delivery of debentures in definitive form and will not be
considered the owners or holders thereof under the indenture. Principal and
interest payments, if any, on debentures registered in the name of DTC or its
nominee will be made to DTC or its nominee, as the case may be, as the
registered owner of the relevant Global Security. None of El Paso, the trustee,
any paying agent or the registrar for the debentures will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.

     We expect that DTC or its nominee, upon receipt of any payment of principal
or interest, if any, will credit immediately participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of the relevant Global Security as shown on the records of
DTC or its nominee. We also expect that payments by participants to owners of
beneficial interests in a Global Security held through these participants will
be governed by standing instructions and customary practices, as is the case
with securities held for the accounts of customers in bearer form or registered
in "street name," and will be the responsibility of the participants.

     If DTC is at any time unwilling or unable to continue as a depositary and a
successor depositary is not appointed by us within 90 days, we will issue
debentures in definitive form in exchange for the entire Global Security for the
debentures. In addition, we may at any time and in our sole discretion determine
not to have debentures represented by a Global Security and, in such event, will
issue debentures in definitive form in exchange for the entire Global Security
relating to the debentures. In any such instance, an owner of a beneficial
interest in a Global Security will be entitled to physical delivery in
definitive form of debentures represented by the Global Security equal in
principal amount to the beneficial interest and to have the debentures
registered in its name. Debentures so issued in definitive form will be issued
as registered debentures in denominations of $1,000 and multiples thereof,
unless otherwise specified by us.

     DTC has advised us as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a clearing corporation within the meaning of the Uniform
Commercial Code and a clearing agency registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and to facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes to the
accounts of its participants. This practice eliminates the need for physical
movement of
                                        26
   29

certificates. Participants include securities brokers and dealers, banks, trust
companies and clearing corporations and may include certain other organizations.
Some of the participants, or their representatives, together with other
entities, own DTC. Indirect access to the DTC system is 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.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Security among participants, it is under no
obligation to perform or continue to perform these procedures, and these
procedures may be discontinued at any time.

     Conveyance of notices and other communications by DTC to participants, by
participants to indirect participants and indirect participants to beneficial
owners will be governed by arrangements among them, subject to any statutory or
regulatory requirements that may be in effect from time to time. Redemption
notices will be sent to Cede & Co., as nominee of DTC. If less than all of the
debentures are being redeemed, DTC will reduce the amount of interest of each
participant in the debentures in accordance with its procedures.

                          DESCRIPTION OF CAPITAL STOCK

     The statements under this caption are brief summaries and are subject to,
and are qualified in their entirety by reference to, the more complete
descriptions contained in (1) our Restated Certificate of Incorporation, as
amended (the "charter"), and the Amended and Restated Shareholder Rights
Agreement, dated as of January 20, 1999, between us and Fleet National Bank c/o
EquiServe, as rights agent (the "shareholder rights agreement"), copies of which
are available upon request to El Paso, and (2) the certificate of designation
relating to each series of preferred stock, which will be filed with the SEC at,
or prior to, the time of the offering of such series of preferred stock.

GENERAL

     We are currently authorized by our charter to issue up to 750,000,000
shares of common stock and up to 50,000,000 shares of preferred stock. As of May
4, 2001, there were 509,175,906 shares of common stock and 200,000 shares of
Series B Mandatorily Convertible Single Reset Preferred Stock issued and
outstanding.

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
common stock are entitled to share ratably in all assets remaining after payment
of liabilities and liquidation preference of any outstanding preferred stock.
Holders of common stock have no preemptive rights and have no rights to convert
their common stock into any other securities. The common stock is not
redeemable. All of the outstanding shares of common stock are, and the common
stock offered by this offering circular will be, fully paid and nonassessable
upon issuance against full payment of the purchase price.

     Fleet National Bank c/o EquiServe is the transfer agent and registrar for
our common stock.

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
resolutions any of the designations, powers, preferences and rights, and the
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
preferred stock.

     The designations, powers, preferences and rights, and the qualifications,
limitations, or restrictions of the preferred stock of each series will be fixed
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:

     - The maximum number of shares to constitute each series and the
       distinctive designation of the shares;

     - The annual dividend rate, if any, on shares of each series, whether such
       rate is fixed or variable or both, the date or dates from which dividends
       will begin to accrue or accumulate and whether dividends will be
       cumulative;
                                        28
   31

     - The purchase price and terms of conditions of the shares of each series,
       including the time during which shares of each series may be redeemed and
       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

     - Any or all other preferences and relative, participating, operational, or
       other special rights, qualifications, limitations, or restrictions on
       each series.

     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
                                        29
   32

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,"

                                        30
   33

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

                                        31
   34

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.

                              PLAN OF DISTRIBUTION

     The debentures and common stock are being registered to permit public
secondary trading of these securities by the selling security holders from time
to time after the date of this prospectus. We have agreed to bear all expenses
in connection with the registration of the debentures and common stock, other
than discounts and commissions. We will not receive any of the proceeds from the
offering of debentures and common stock by the selling security holders or the
issuance of common stock on conversion of the debentures.

     The selling security holders (and their respective donees and transferees
for no consideration) may sell all or a portion of the debentures and common
stock beneficially owned by them and offered by this prospectus from time to
time on any exchange on which the securities are listed on terms to be
determined at the time of sale. The selling security holders may also make
private sales directly or through a broker. Alternatively, any of the selling
security holders may from time to time offer the debentures and common stock
beneficially owned by them through dealers or agents, who may receive
compensation in the form of commissions or concessions from the selling security
holders and the purchasers for whom they may act as agent. The aggregate
proceeds to the selling security holders from the sale of the debentures and
common stock offered by them will be the purchase price less discounts and
commissions, if any.

     The debentures and common stock may be sold from time to time in one or
more transactions at fixed offering prices, which may be changed, or at varying
prices determined at the time of sale or at negotiated prices. Prices will be
determined by the holders of the securities or by agreement between the holders
and dealers who may receive fees or commissions in connection with the sale.

     The shares of our common stock offered by this prospectus are issuable on
conversion of the debentures. Holders may convert the debentures into shares of
our common stock at any time before maturity at a conversion rate of 4.7872
shares per $1,000 principal amount at maturity. See "Description of Debentures".
We will not receive any cash proceeds on conversion of the debentures.

     Our common stock is traded on the New York Stock Exchange under the symbol
"EPG."

     CSFB is making a market in the debentures; however, it is not obligated to
do so and any such market-making may be discontinued at any time without notice,
in the sole discretion of CSFB. We do not intend to apply for listing of the
debentures on any securities exchange. Accordingly, no assurance can be given as
to the development or liquidity of any trading market that may develop for the
debentures.

     The selling security holders and any broker-dealers or agents that
participate with the selling security holders in the distribution of the
securities offered pursuant to this prospectus may be deemed to be
"underwriters" within the meaning of the Securities Act, in which event any
commissions received by the broker-dealers or agents and any profits realized by
the selling security holders on the resales of the debentures and common stock
purchased by them may be deemed to be underwriting commissions or discount under
the Securities Act.

     In addition, any securities covered by this prospectus which qualify for
sale pursuant to Rule 144, Rule 144A or any other available exemption from
registration under the Securities Act may be sold under Rule 144, Rule 144A or
such other available exemption rather than pursuant to this prospectus. There is
no assurance that any selling security holder will sell any or all of the
debentures and common stock described in this prospectus, and any selling
security holder may transfer, devise or gift such securities by other means not
described in this prospectus.

     We originally sold the debentures to CSFB on February 28, 2001 in a private
placement. We agreed to indemnify and hold CSFB harmless against certain
liabilities under the Securities Act that could arise in connection with the
sale of the debentures by CSFB. The registration rights agreement pursuant to
which we filed the registration statement to which this prospectus relates
provides for us and the selling security holders to indemnify each other against
certain liabilities arising under the Securities Act.

                                        33
   36

     In the ordinary course of business, CSFB and certain of its affiliates have
in the past and may in the future engage in investment banking or other
transactions of a financial nature with us and our affiliates, including
providing advisory services to us, for which they have received customary
compensation.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the material United States federal income tax
considerations to U.S. holders and the material U.S. federal income and estate
tax considerations to non-U.S. holders relating to the purchase, ownership and
disposition of the debentures or shares of common stock. This discussion is
limited to holders of debentures who hold the debentures and any shares of
common stock into which the debentures are converted as capital assets.

     This discussion does not contain a complete analysis of all the potential
tax considerations relating to the purchase, ownership and disposition of the
debentures or shares of common stock. In particular, this discussion does not
address all tax considerations that may be important to you in light of your
particular circumstances such as the alternative minimum tax provisions or
special rules applicable to certain categories of investors. Special rules may
apply, for instance, to certain financial institutions, insurance companies,
tax-exempt organizations, dealers in securities, persons who hold debentures or
shares of common stock as part of a hedge, conversion or constructive sale
transaction, or straddle or other integrated or risk reduction transaction, or
persons who have ceased to be United States citizens or to be taxed as resident
aliens. In addition, the discussion does not apply to holders of debentures or
shares of common stock which are partnerships. This discussion also does not
address the tax consequences arising under the laws of any foreign, state or
local jurisdiction.

     This discussion is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), existing and proposed Treasury Regulations, and judicial decisions
and administrative interpretations thereunder, as of the date hereof, all of
which are subject to change or different interpretations, possibly with
retroactive effect. We cannot assure you that the Internal Revenue Service will
not challenge one or more of the tax results described herein, and we have not
obtained, nor do we intend to obtain, a ruling from the IRS with respect to the
U.S. federal tax consequences of acquiring, holding or disposing of the
debentures or shares of common stock.

     Please consult your own tax advisors as to the particular tax consequences
to you of acquiring, holding, converting or otherwise disposing of the
debentures and shares of common stock, including the effect and applicability of
state, local or foreign tax laws.

U.S. HOLDERS

     You are a "U.S. holder" for purposes of this discussion if you are a holder
of a debenture or common stock that is, for U.S. federal income tax purposes:

     - a citizen or resident of the United States;

     - a corporation created or organized in or under the laws of the United
       States or of any political subdivision thereof;

     - an estate the income of which is subject to U.S. federal income taxation
       regardless of its source; or

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

     Original Issue Discount on the Debentures.  The debentures were issued at a
substantial discount from their principal amount. For U.S. federal income tax
purposes, the excess of the principal amount of each debenture over its issue
price constitutes original issue discount, or OID. The issue price of the
debentures was $452.89 per $1000 principal amount at maturity. Thus, the OID of
the debentures equals $547.11 per $1000 principal amount at maturity. As the
holder of a debenture, subject to the rules for acquisition premium described
below, you will be required to include OID in income as it accrues, in
                                        34
   37

accordance with a constant yield method, before receipt of the cash or stock
attributable to that income, regardless of your regular method of accounting for
U.S. federal income tax purposes. Under these rules, you will have to include in
gross income increasingly greater amounts of OID in each successive accrual
period. Your original tax basis for determining gain or loss on the sale or
other disposition of a debenture will be increased by any accrued OID included
in your gross income.

     Acquisition Premium. A U.S. holder of a debenture is generally subject to
the rules for accruing OID described above. However, if your purchase price for
the debenture exceeds the adjusted issue price but is less than or equal to the
sum of all amounts payable on the debenture after the purchase date, the excess
is acquisition premium and is subject to special rules. The adjusted issue price
of a debenture will be the issue price of the debenture increased by the accrued
OID included in your income for all prior accrual periods.

     Acquisition premium ratably offsets the amount of accrued OID otherwise
includible in your taxable income, that is, you may reduce the daily portions of
OID by a fraction, the numerator of which is the excess of your purchase price
for the debenture over the adjusted issue price, and the denominator of which is
the excess of the sum of all amounts payable on the debenture after the purchase
date over the debenture's adjusted issue price. As an alternative to reducing
the amount of OID otherwise includible in income by this fraction, you may elect
to compute OID accruals with respect to the debentures by treating the purchase
as a purchase at original issue and applying the rules described above under
" -- Original Issue Discount on the Debentures."

     Market Discount. Under the market discount rules of the Code, a U.S. holder
who purchases a debenture at a market discount generally will be required to
treat any gain recognized on the disposition of the debenture as ordinary income
to the extent of the lesser of the gain or the portion of the market discount
that accrued during the period that the U.S. holder held the debenture. Market
discount is generally defined as the amount by which your purchase price for a
debenture is less than the revised issue price of the debenture on the date of
purchase, subject to a statutory de minimis exception. A debenture's revised
issue price equals the sum of the issue price of the debenture and the aggregate
amount of the OID includible in the gross income of all holders of the debenture
for periods before the acquisition of the debenture by the holder, likely
reduced, although the Code does not expressly so provide, by any cash payment in
respect of the debenture. If you acquire a debenture at a market discount you
may be required to defer a portion of any interest expense that otherwise may be
deductible on any indebtedness incurred or continued to purchase or carry the
debenture until you dispose of the debenture in a taxable transaction.

     A U.S. holder who has elected under applicable Code provisions to include
market discount in income annually as the discount accrues will not, however, be
required to treat any gain recognized as ordinary income or to defer any
deductions for interest expense under these rules. In that case your tax basis
in a debenture is increased by each accrual of amounts treated as market
discount. This election to include market discount in income currently, once
made, applies to all market discount obligations acquired on or after the first
day of the taxable year to which the election applies and may not be revoked
without the consent of the IRS. U.S. holders should consult their tax advisors
as to the portion of any gain that would be taxable as ordinary income under
these provisions and any other consequences of the market discount rules that
may apply to them in particular.

     Election to Treat All Interest as Original Issue Discount. U.S. holders may
elect to include in gross income all amounts in the nature of interest that
accrue on a debenture, including any stated interest, acquisition discount, OID,
market discount, de minimis market discount and unstated interest, as adjusted
by acquisition premium, by using the rules described above under " -- Original
Issue Discount on the Debentures." An election for a debenture with market
discount results in a deemed election to accrue market discount in income
currently for the debenture and for all other bonds you acquire with market
discount on or after the first day of the taxable year to which the election
first applies, and may be revoked only with permission of the IRS. Your tax
basis in a debenture is increased by each accrual of the amounts treated as OID
under the election described in this paragraph.

                                        35
   38

     Sale, Exchange or Retirement of the Debentures.  Except as described below,
upon the sale, exchange or retirement of a debenture, you will recognize gain or
loss equal to the difference between the sale or redemption proceeds and your
adjusted tax basis in the debenture. Your adjusted tax basis in a debenture will
generally equal your cost of the debenture increased by any OID or market
discount previously included in income with respect to the debenture. Subject to
the market discount rules discussed above, gain or loss realized on the sale,
exchange or retirement of a debenture will generally be capital gain or loss and
will be long term capital gain or loss if the debenture is held for more than
one year. You should consult your tax advisors regarding the treatment of
capital gains (which may be taxed at lower rates than ordinary income for
taxpayers who are individuals) and losses (the deductibility of which is subject
to limitations). Our election to pay interest on the debentures instead of
accruing OID will not constitute a taxable exchange of the debentures to the
holders, although the timing of income could be affected.

     Conversion of Debentures.  The conversion of a debenture into common stock
will generally not be a taxable event, except with respect to cash received in
lieu of a fractional share. To the extent the debentures converted into common
stock have accrued market discount, the amount of the unrecognized accrued
market discount will carry over to the common stock and will be treated as
ordinary income upon disposition of that common stock. Your basis in the common
stock received on conversion of a debenture will be the same as your basis in
the debenture at the time of conversion, exclusive of any tax basis allocable to
a fractional share. The holding period for the common stock received on
conversion will include the holding period of the converted debenture, except
that the holder's holding period for common stock attributable to accrued OID
may commence on the day following the date of conversion. Subject to the market
discount rules discussed above, the receipt of cash in lieu of a fractional
share upon conversion of a debenture should generally result in capital gain or
loss measured by the difference between the cash received for the fractional
share interest and your tax basis in the debenture allocable to the fractional
share interest.

     Exercise of Repurchase Right.  If you require us to repurchase a debenture
on a repurchase date and if we issue shares of common stock in full satisfaction
of the repurchase price, the exchange of a debenture for shares of common stock
will be treated the same as a conversion. If you require us to repurchase a
debenture on a repurchase date and if we deliver a combination of cash and
common stock in payment of the repurchase price, then, in general, you will
realize gain, but not loss, to the extent that the cash and the value of the
common stock exceeds your adjusted tax basis in the debenture, but in no event
will the amount of recognized gain exceed the amount of cash received. This gain
will be subject to the rules governing market discount discussed above. Your
basis in the common stock received will be the same as your basis in the
debenture tendered, except for any basis allocable to a fractional share,
decreased by the amount of cash received, other than cash received in lieu of a
fractional share, and increased by the amount of any gain recognized, other than
with respect to a fractional share. The holding period of the common stock
received in the exchange will include the holding period for the debenture
tendered to us, except that the holding period of shares attributable to OID may
commence on the day following the date of delivery. Subject to the market
discount rules discussed above, the receipt of cash in lieu of a fractional
share of common stock should generally result in capital gain or loss measured
by the difference between the cash received for the fractional share interest
and your tax basis in the debenture allocable to the fractional share interest.
To the extent the debentures tendered in exchange for common stock have accrued
market discount, the amount of the unrecognized accrued market discount will
carry over to the common stock and will be treated as ordinary income upon
disposition of that common stock.

     Adjustment of Conversion Rate.  If at any time we make a distribution of
property to stockholders that would be taxable to the stockholders as a dividend
for U.S. federal income tax purposes (for example, distributions of evidences of
indebtedness or assets of ours, but generally not stock dividends or rights to
subscribe for common stock) and, pursuant to the anti-dilution provisions of the
indenture, the conversion rate of the debentures is increased, that increase may
be deemed to be the payment of a taxable dividend to you. If the conversion rate
is increased at our discretion or in certain other circumstances, that increase
also may be deemed to be the payment of a taxable dividend to you.

                                        36
   39

     Ownership and Disposition of Common Stock.  Distributions, if any, paid on
shares of common stock generally will be includable in your income as ordinary
income to the extent made from our current or accumulated earnings and profits.
Subject to the market discount rules discussed above, upon the sale, exchange or
other disposition of shares of common stock, you generally will recognize
capital gain or capital loss equal to the difference between the amount realized
on the sale or exchange and your adjusted tax basis in the shares. You should
consult your tax advisors regarding the treatment of capital gains, which may be
taxed at lower rates than ordinary income for taxpayers who are individuals, and
losses, the deductibility of which is subject to limitations.

NON-U.S. HOLDERS

     You are a "non-U.S. holder" for purposes of this discussion if you are a
holder of a debenture or common stock that is not a U.S. holder as described
above.

     Withholding Tax on Payments of Principal and Original Issue Discount on
Debentures.  The payment to you of principal, including any OID included
therein, on a debenture by us or any of our paying agents will not be subject to
U.S. federal withholding tax, provided that in the case of a payment in respect
of OID:

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

     - you are not a controlled foreign corporation that is related to us within
       the meaning of the Internal Revenue Code; and

     - either (A) the beneficial owner of the debenture certifies to the
       applicable payor or its agent, under penalties of perjury, that it is not
       a U.S. holder and provides its name and address on U.S. Treasury Form
       W-8BEN (or a suitable substitute form), or (B) a securities clearing
       organization, bank or other financial institution, that holds customers'
       securities in the ordinary course of its trade or business and holds the
       debenture, certifies under penalties of perjury that such a Form W-8BEN
       (or a suitable substitute form) has been received from the beneficial
       owner by it or by a financial institution between it and the beneficial
       owner and furnishes the payor with a copy thereof.

     Under section 871(h)(4) of the Code, otherwise exempt interest and OID is
subject to U.S. federal withholding tax if such interest or OID is based on
certain enumerated equity-like features. Although the IRS has not provided any
guidance regarding the application of this provision to an instrument such as a
debenture, we have been advised that this section should not apply and,
accordingly, do not plan to withhold amounts, provided the conditions above are
met.

     Except to the extent otherwise provided under an applicable tax treaty, you
generally will be taxed in the same manner as a U.S. holder with respect to OID
on a debenture if that OID is effectively connected with a U.S. trade or
business of yours. Effectively connected OID received by a non-U.S. holder which
is a foreign corporation may also be subject to an additional "branch profits
tax" at a 30% rate or, if applicable, a lower treaty rate, subject to certain
adjustments. That effectively connected OID will not be subject to withholding
tax if the holder delivers a U.S. Treasury Form W-8ECI to the payor.

     Dividends.  Dividends, if any, paid to you on shares of our common stock
generally will be subject to a 30% U.S. federal withholding tax, subject to
reduction if you are eligible for the benefits of an applicable income tax
treaty. You will be required to satisfy certain certification requirements in
order to claim treaty benefits. Except to the extent otherwise provided under an
applicable tax treaty, you generally will be taxed in the same manner as a U.S.
holder on dividends that are effectively connected with your conduct of a trade
or business in the United States. If you are a foreign corporation, you may also
be subject to a U.S. branch profits tax on such effectively connected income at
a 30% rate or such lower rate as may be specified by an applicable income tax
treaty, subject to certain adjustments.

     Gain on Disposition of the Debentures and Common Stock.  You generally will
not be subject to U.S. federal income tax on gain realized on the sale, exchange
or redemption of a debenture, including the
                                        37
   40

exchange of a debenture for shares of common stock, or the sale or exchange of
shares of common stock unless:

     - you are an individual present in the United States for 183 days or more
       in the year of such sale, exchange or redemption and either (A) you have
       a "tax home" in the United States and certain other requirements are met,
       or (B) the gain from the disposition is attributable to an office or
       other fixed place of business in the United States;

     - in the case of an amount which is attributable to OID, you do not meet
       the conditions for exemption from U.S. federal withholding tax, as
       described in "Withholding Tax on Payments of Principal and Original Issue
       Discount on Debentures," above;

     - the gain is effectively connected with your conduct of a United States
       trade or business; or

     - we are, or have been during certain periods, a U.S. real property holding
       corporation for U.S. federal income tax purposes.

     If we are or have been a U.S. real property holding corporation, a non-U.S.
holder will generally not be subject to U.S. federal income tax on gain
recognized on a sale or other disposition of our common stock provided that the
non-U.S. holder does not hold, and has not held during certain periods, directly
or indirectly, more than 5% of the outstanding debentures or more than 5% of our
outstanding common stock, and our common stock continues to be regularly traded
on an established securities market for U.S. federal income tax purposes. If we
are or have been a U.S. real property holding corporation and the above
exception does not apply, a non-U.S. holder will be subject to U.S. federal
income tax with respect to gain realized on any sale or other disposition of our
common stock as well as to withholding tax, generally at a rate of 10% on the
proceeds. Any amount withheld pursuant to a withholding tax will be creditable
against a non-U.S. holder's U.S. federal income tax liability.

     U.S. Federal Estate Tax.  A debenture held by an individual who at the time
of death is not a citizen or resident of the United States, as specially defined
for U.S. federal estate tax purposes, will not be subject to U.S. federal estate
tax if the individual did not actually or constructively own 10% or more of the
total combined voting power of all classes of our stock and, at the time of the
individual's death, payments with respect to the debenture would not have been
effectively connected with the conduct by the individual of a trade or business
in the United States. Common stock held by an individual who at the time of
death is not a citizen or resident of the United States, as specially defined
for U.S. federal estate tax purposes, will be included in the individual's
estate for U.S. federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     U.S. Holders.  OID and any payments of interest or dividends made by us on,
or the proceeds of the sale or other disposition of, the debentures or shares of
common stock may be subject to information reporting and U.S. federal backup
withholding tax at the rate of 31% if the recipient of such payment fails to
supply an accurate taxpayer identification number or otherwise fails to comply
with applicable United States information reporting or certification
requirements. Any amount withheld from a payment to a U.S. holder under the
backup withholding rules is allowable as a credit against the holder's U.S.
federal income tax, provided that the required information is furnished to the
IRS.

     Non-U.S. Holders.  If you are a non-U.S. holder you may have to comply with
certification procedures to establish that you are not a U.S. person in order to
avoid backup withholding tax requirements with respect to our payments of
principal, including cash payments in respect of OID, on the debentures. In
addition, we must report annually to the IRS and to each non-U.S. holder the
amount of any dividends paid to, and the tax withheld with respect to, such
holder, regardless of whether any tax was actually withheld. Copies of these
information returns may also be made available under the provisions of a
specific treaty or agreement to the tax authorities of the country in which the
non-U.S. holder resides.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS OF EL PASO CORPORATION.

     Section 145 of the Delaware General Corporation Law (the "DGCL") provides
that a corporation may indemnify directors and officers as well as other
employees and individuals against expenses (including attorneys' fees),
judgments, fines, and amounts paid in settlement in connection with specified
actions, suits, proceedings whether civil, criminal, administrative, or
investigative (other than action by or in the right of the corporation -- a
"derivative action"), if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is
applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys' fees) incurred in connection with the
defense or settlement of such action, and the statute requires court approval
before there can be any indemnification where the person seeking indemnification
has been found liable to the corporation. The statute provides that it is not
exclusive of other indemnification that may be granted by a corporation's
charter, by-laws, disinterested director vote, stockholder vote, agreement, or
otherwise.

     Article X of the by-laws of El Paso requires indemnification to the full
extent permitted under Delaware law as from time to time in effect. Subject to
any restrictions imposed by Delaware law, the by-laws of El Paso provide an
unconditional right to indemnification for all expense, liability, and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes, or penalties
and amounts paid in settlement) actually and reasonably incurred or suffered by
any person in connection with any actual or threatened proceeding (including, to
the extent permitted by law, any derivative action) by reason of the fact that
such person is or was serving as a director or officer or employee of El Paso,
such person or is or was serving at the request of El Paso as a director,
officer, employee or agent of another corporation or of a partnership, joint
venture, trust, or other enterprise, including service with respect to an
employee benefit plan. The by-laws of El Paso also provide that El Paso may, by
action of its board of directors, provide indemnification to its agents with the
same scope and effect as the foregoing indemnification of directors and
officers.

     Section 102(b)(7) of the DGCL permits a corporation to provide in its
certificate of incorporation that a director of the corporation shall not be
personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability for (i) any
breach of the director's duty of loyalty to the corporation or its stockholders,
(ii) acts of omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) payment of unlawful dividends or unlawful
stock purchases or redemptions, or (iv) any transaction from which the director
derived an improper personal benefit.

                                       II-1
   44

     Article 10 of El Paso's restated certificate of incorporation, as amended,
provides that to the full extent that the DGCL, as it now exists or may
hereafter be amended, permits the limitation or elimination of the liability of
directors, a director of El Paso shall not be liable to El Paso or its
stockholders for monetary damages for breach of fiduciary duty as a director.
Any amendment to or repeal of such Article 10 shall not adversely affect any
right or protection of a director of El Paso for or with respect to any acts or
omissions of such director occurring prior to such amendment or repeal.

     El Paso maintains directors' and officers' liability insurance which
provides for payment, on behalf of the directors and officers of El Paso and its
subsidiaries, of certain losses of such persons (other than matters uninsurable
under law) arising from claims, including claims arising under the Securities
Act of 1933, as amended ("Securities Act") for acts or omissions by such persons
while acting as directors or officers of El Paso and/or its subsidiaries, as the
case may be.

ITEM 17. UNDERTAKINGS.

     The undersigned registrants hereby undertake:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement: (i) to
     include any prospectus required by Section 10(a)(3) of the Securities Act
     of 1933; (ii) to reflect in the prospectus any facts or events arising
     after the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement; notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective Registration Statement; and (iii) to include any material
     information with respect to the plan of distribution not previously
     disclosed in the Registration Statement or any material change to such
     information in the Registration Statement; provided, however, that clauses
     (i) and (ii) do not apply if the information required to be included in a
     post-effective amendment by those clauses is contained in periodic reports
     filed by El Paso pursuant to Section 13 or 15(d) of the Securities Exchange
     Act of 1934 that are incorporated by reference in the Registration
     Statement.

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

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

          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of El Paso's annual report pursuant to
     Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
     incorporated by reference in the Registration Statement shall be deemed to
     be a new registration statement relating to the securities offered herein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (5) To file an application for the purpose of determining the
     eligibility of the trustee to act under subsection (a) of Section 310 of
     the Trust Indenture Act of 1939 in accordance with the rules and
     regulations prescribed by the Commission under Section 305(b)(2) of the
     Trust Indenture Act of 1939.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
of the Registrants pursuant to the provisions of Item 15. of this Registration
Statement, or otherwise, each Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by El Paso of expenses incurred or paid by a
director, officer or controlling person of each of the Registrants in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, each Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy, as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.
