[REVERSE OF SECURITY]

El Paso Corporation
7.25% Senior Note due 2018

     This Security is one of a duly authorized issue of securities of the Company (the “Securities”), issued and to be issued in one or more series under an Indenture dated as of May 10, 1999 (as amended and supplemented from time to time, the “Indenture”), between the Company and HSBC Bank USA, National Association, as Trustee (the “Trustee”, which term includes any successor trustee under the Indenture), as supplemented by the Thirteenth Supplemental Indenture dated as of May 30, 2008, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture, the Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest, if any, at different rates, may be subject to different redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided or permitted.

     The Securities of this series are redeemable, upon not less than 30 nor more than 60 days’ notice, at any time in whole or from time to time in part, at the option of the Company at a Redemption Price (the “Make-Whole Price”) equal to the greater of (i) 100% of the principal amount thereof and (ii) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest thereon from the Redemption Date to Maturity, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate less accrued and unpaid interest thereon to the Redemption Date, plus, in each case, accrued and unpaid interest thereon to the Redemption Date, but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.

     The notice of redemption shall set forth the manner of calculation of the Make-Whole Price, but not necessarily its amount. The Company shall notify the Trustee of the amount of the Make-Whole Price with respect to any redemption promptly after the calculation thereof, and the Trustee shall not be responsible for the accuracy of the calculation. Unless the Company defaults in payment of the Make-Whole Price, on and after the applicable Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

A-5

     “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) assuming a price for the Comparable Treasury Issue that is the same as the Comparable Treasury Price for such redemption date, plus 0.50%.

     “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

     “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

     “Independent Investment Banker” means any of Deutsche Bank Securities Inc., Xxxxxxx, Xxxxx & Co. and X.X. Xxxxxx Securities Inc., and their respective successors, or, if any such firm or their successors, if any, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

     “Reference Treasury Dealer” means Deutsche Bank Securities Inc., Xxxxxxx, Xxxxx & Co., X.X. Xxxxxx Securities Inc. and one additional primary U.S. government securities dealer in New York City selected by the Company, and their respective successors (provided, however, that if any such firm or any such successor shall cease to be a primary U.S. government securities dealer in New York City, the Company shall substitute therefor another dealer).

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

     If a Change of Control Triggering Event occurs, unless the Company has exercised its option to redeem all Securities of this series then outstanding, the Company will make an offer to each Holder of Securities of this series to repurchase all or any part (in integral multiples of $1,000) of that Holder’s Securities of this series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased plus any accrued and unpaid interest on the Securities of this series repurchased to the date

A-6

of purchase. Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase Securities of this series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment date specified in the notice. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Securities of this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Securities of this series by virtue of such conflict.

     (1) accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to the offer;

     (2) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered; and

     (3) deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an officers’ certificate stating the aggregate principal amount of Securities of this series being purchased by the Company.

     The Company will not be required to make an offer to repurchase the Securities of this series upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Securities of this series properly tendered and not withdrawn under its offer.

     “Change of Control” means the occurrence of any of the following:

     (1) the direct or indirect sale, lease or exchange (other than by way of merger or consolidation), in one transaction or a series of related transactions, of all or substantially all of the assets of the Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) other than the Company or one of its subsidiaries; or

A-7

     (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above), becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s Voting Stock, measured by voting power rather than number of shares.

     “Change of Control Triggering Event” means (a) the occurrence of a Change of Control and (b) during the period beginning on the earlier of (i) the date of the public notice of the Company’s intention to effect such Change of Control and (ii) the occurrence of such Change of Control and ending 90 days after the occurrence of such Change of Control, (x) if three Rating Agencies are continuing to provide ratings for the Securities of this series on such date, more than one of the Rating Agencies rating the Securities of this series at such time shall downgrade, below the rating as of the date of the supplemental indenture establishing the terms of the Securities of this series, its respective rating of the Securities of this series as a result of such Change of Control, (y) if fewer than three Rating Agencies are continuing to provide ratings for the Securities of this series on such date, any of the Rating Agencies rating the Securities of this series at such time shall downgrade, below the rating as of the date of the supplemental indenture establishing the terms of the Securities of this series, its respective rating of the Securities of this series as a result of such Change of Control, or (z) no Rating Agency provides a rating for the Securities of this series.

     “Fitch” means Fitch Inc.

     “Moody’s” means Xxxxx’x Investor Services Inc.

     “Rating Agency” means (1) each of Xxxxx’x, S&P and Fitch; and (2) if any of Moody’s, S&P or Fitch ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Securities Exchange Act of 1934, as amended, selected by the Company (as certified by a resolution of the Company’s board of directors) as a replacement agency for Moody’s, S&P or Fitch, or all, as the case may be.

     “S&P” means Standard & Poor’s Ratings Services, a division of XxXxxx-Xxxx, Inc.

     “Voting Stock” of any specified “person” (as defined above) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

A-8

     In the event of redemption or repurchase of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed or unpurchased portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

     If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Outstanding Securities of all affected series (voting as one class), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture. The Indenture permits, with certain exceptions as therein provided, the Holders of a majority in principal amount of Securities of any series then Outstanding to waive past defaults under the Indenture with respect to such series and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

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

A-9

absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the times, place(s) and rate, and in the coin or currency, herein prescribed.

     [This Global Security or portion hereof may not be exchanged for Definitive Securities of this series except in the limited circumstances provided in the Indenture.

     The holders of beneficial interests in this Global Security will not be entitled to receive physical delivery of Definitive Securities except as described in the Indenture and will not be considered the Holders thereof for any purpose under the Indenture.]⁵

     [As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in the Borough of Manhattan, The City of New York or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or its attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.]⁶

     The Securities of this series are issuable only in registered form without coupons in denominations of U.S.$1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

     This Security may be surrendered for registration of transfer and exchange at the Corporate Trust Office.

     No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
