SECURITIES ACT) (A “QIB”) OR (B) IT IS NOT A U.S. PERSON, IS NOT ACQUIRING THIS SECURITY FOR THE ACCOUNT OR BENEFIT OF A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE
SECURITIES ACT, 
 (2) AGREES THAT IT WILL NOT, WITHIN THE TIME PERIOD REFERRED TO UNDER RULE 144(k) (TAKING
INTO ACCOUNT THE PROVISIONS OF RULE 144(d) UNDER THE SECURITIES ACT, IF APPLICABLE) UNDER THE SECURITIES ACT AS IN EFFECT ON THE DATE OF THE TRANSFER OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER OR ANY
SUBSIDIARY THEREOF, (B) TO A PERSON WHOM THE HOLDER REASONABLY BELIEVES IS A QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE

 (3) AGREES
THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY OR AN INTEREST HEREIN IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(D) OR (2)(E) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 

IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY OR ANY INTEREST HEREIN WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE
HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND
“U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. 

(2) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security
represented by a Global Note) pursuant to Rule 144 under the Securities Act or an effective registration statement under the Securities Act, which in either case shall be certified by the Company to the Trustee and the Security Registrar upon which

restriction on the transfer of such Transfer Restricted Security; and 

 (b) in the case of any Transfer Restricted Security represented by a
Global Note, such Transfer Restricted Security shall not be required to bear the legend(s) set forth in (1) above if all other interests in such Global Note have been or are concurrently being sold or transferred pursuant to Rule 144 under the
Securities Act or pursuant to an effective registration statement under the Securities Act, but such Transfer Restricted Security shall continue to be subject to the provisions of Section 305 of the Original Indenture and this Section 2.06

With respect only to the Notes of each series, in addition to the other events or circumstances set forth as Events of Default in
Section 501 of the Original Indenture, the following event shall constitute an Event of Default: default in the payment of Liquidated Damages (as defined in the Registration Rights Agreement), if any, when such Liquidated Damages become due and

 SECTION
2.10. Redemption of 6.70% Senior Notes due 2027.
 Notwithstanding anything to the contrary
set forth herein or in the Indenture, the provisions of this Section 2.10 shall apply to, and be for the equal and proportionate benefit of all Holders of, only the 6.70% Senior Notes due 2027 (for the purposes of this Section 2.10, the
“ 6.70% Notes ”). 
 (1) The 6.70% Notes are not redeemable at the Company’s option
prior to their Stated Maturity. On February 15, 2007, or if such date is not a Business Day, then the next succeeding Business Day (for the purposes of this Section 2.10, the “ Redemption Date ”), each Holder of 6.70%
Notes will have the right (for the purposes of this Section 2.10, the “ Redemption Right ”) to require the Company to redeem all or any part (equal to $1,000 in principal amount or an integral multiple thereof) of such
Holder’s 6.70% Notes, in accordance with the provisions set forth herein, for cash at a purchase price equal to 100% of the aggregate principal amount thereof (for the purposes of this Section 2.10, the “ Redemption Price
”), plus accrued and unpaid interest, if any, thereon to the Redemption Date. 
 (2) On or prior to
November 30, 2006, the Company shall send, by first class mail, postage prepaid, a notice of the Redemption Right to each Holder of 6.70% Notes at its address appearing in the Security Register, with a copy to the Trustee, stating: 

 (a) that such Holder has the Redemption Right; 

(b) the Redemption Date; 
 (c) the Redemption Price (including the amount of any accrued and unpaid interest); 
 (d) that any 6.70% Note not submitted for redemption will continue to accrue interest; 
 (e) that on the Redemption Date the Redemption Price shall become due and payable upon each 6.70% Note submitted for redemption pursuant to the Redemption Right and that, unless the Company defaults
in paying the Redemption Price therefor, any 6.70% Note submitted for redemption pursuant to the Redemption Right shall cease to accrue interest after the Redemption Date; 

(f) that any Holder electing to have a 6.70% Note redeemed pursuant to the Redemption Right will be required to
surrender the 6.70% Note, or transfer the 6.70% Note by book-entry, with the form entitled “Option of Holder to Elect Redemption on February 15, 2007” on the reverse side of such 6.70% Note, duly completed, to the Trustee during the
period from December 15, 2006 and prior to 5:00 p.m. (New York City time) on January 15, 2007 (or if such date is not a Business Day, then the next succeeding Business Day) at the address specified in such notice; 

(g) that any election on the part of a Holder to exercise the Redemption Right effected in accordance herewith shall
be irrevocable on the part of the Holder and may not be withdrawn; and 
 (h) that Holders whose 6.70%
Notes are being redeemed only in part will be issued a new 6.70% Note or 6.70% Notes equal in principal amount to the unredeemed portion of the 6.70% Notes surrendered (which unredeemed portion must be equal to $1,000 in principal amount or an
integral multiple thereof). 
 (3) On or prior to the Redemption Date, the Company shall deposit with the
Trustee or with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003 of the Indenture) an amount of cash sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) any accrued and unpaid interest on, all 6.70% Notes or portions thereof which are to be redeemed on that date. 

(4) The 6.70% Notes to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price
thereof and from and after such date (unless the Company shall default in the payment of the Redemption Price) such 6.70% Notes shall cease to bear interest. Upon submission of any 6.70% Note for redemption in accordance with the provisions hereof,
such 6.70% Note shall be paid by the Company at the Redemption Price, plus accrued and unpaid interest, if any, to the Redemption Date; provided , however , that installments of interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such 6.70% Notes registered as such on the relevant Record Date according to the terms and provisions hereof and Section 307 of the Indenture. 

(5) If any 6.70% Note is to be redeemed in part, the Company shall execute and the Trustee, upon Company Order, shall
authenticate and deliver to the Holder of such 6.70% Note, without service charge, a new 6.70% Note or 6.70% Notes equal in principal amount to the unredeemed portion of the 6.70% Note surrendered (which unredeemed portion must be equal to $1,000 in
principal amount or an integral multiple thereof). 
 (6) The Company shall comply with the requirements of
Rule 14e-1 under the Securities Exchange Act of 1934, as amended, and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable to the redemption of the 6.70% Notes pursuant to the Redemption Right.
To the extent that the provisions of any such rule conflict with the provisions hereof relating to the Redemption Right, the Company shall comply with the provisions of such rule and be deemed not to have breached its obligations relating to the
Redemption Right by virtue thereof. 

 (7) All questions regarding the validity, form, eligibility (including
time of receipt) and acceptance of any 6.70% Notes for redemption will be determined by the Company, and its determination will be final and binding. 
 SECTION 2.11. Redemption of 7.75% Senior Notes due 2032.
 Notwithstanding anything to the contrary set forth herein or in the Indenture, the provisions of this Section 2.11 shall apply to, and be for the equal and proportionate benefit of all Holders of,
only the 7.75% Senior Notes due 2032 (for the purposes of this Section 2.11, the “ 7.75% Notes ”). 
 (1) Each 7.75% Note will be subject to redemption at the option of the Company on any date on and after the Redemption Commencement Date specified on the face thereof, in whole or from time to time
in part, at the Make-Whole Price (as defined below), on notice given no more than 60 nor less than 30 calendar days prior to the date of redemption (for the purposes of this Section 2.11, the “ Redemption Date ”) and in
accordance with the provisions of the Indenture. 
 (2) For the purposes of this Section 2.11,
“Make-Whole Price” means an amount equal to the greater of (i) 100% of the principal amount of a 7.75% Note to be redeemed and (ii) as determined by an Independent Investment Banker (as defined below), the sum of the
present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 25 basis points, plus, in the case of both (i) and (ii), accrued and unpaid interest to the Redemption Date. Unless the Company defaults in payment of
the Make-Whole Price, on and after the Redemption Date, interest will cease to accrue on the principal amount of a 7.75% Note to be redeemed. In the event of redemption of the 7.75% Note in part only, a new 7.75% Note of like tenor for the
unredeemed portion thereof and otherwise having the same terms as the 7.75% Note shall be issued in the name of the Holder thereof upon the presentation and surrender thereof. 

(3) For the purposes of this Section 2.11, 

(a) “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 a 7.75% Note that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of such 7.75% Note; 
 (b) “Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or
(ii) if the Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations; 
 (c) “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company; 

(d) “Reference Treasury Dealer” means (i) Banc of America Securities LLC; ABN AMRO
Incorporated; BNP Paribas Securities Corp.; Credit Lyonnais Securities (USA) Inc. and J.P. Morgan Securities Inc. and their respective successors; provided , however , that if any of the foregoing shall not be a primary U.S. government
securities dealer in New York City (for the purposes of this Section 2.11, a “ Primary Treasury Dealer ”), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any two other Primary Treasury
Dealers the Company selects; 
 (e) “Reference Treasury Dealer Quotations” means, with
respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date; and 

 (f) “Treasury Rate” means, with respect to any
Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication that
is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,”
for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be
determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

(4) Notwithstanding Section 1104 of the Indenture, the notice of redemption with respect to the foregoing
redemption need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company shall notify the Trustee of the Make-Whole Price with respect to the foregoing redemption promptly after the calculation thereof, and the
Trustee shall not be responsible for such calculation.

 [REVERSE OF 10 3/4% SENIOR NOTE DUE 2010] 

EL PASO CORPORATION 
 10 
3/4% Senior Note due 2010 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original
Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as
trustee (the “ Trustee ,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This note is one of the notes in a series designated as 10 3/4% Senior Notes due 2010 of the Company (hereinafter called the
“ 10 3/4% Notes ”), issued under the Original Indenture, which
10 3/4% Notes are limited in aggregate principal
amount to $56,573,000. 
 Except as provided in Sections 1006 and 1007 of the Original
Indenture, neither the Indenture nor the 10 3/4%
Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 10 3/4% Notes issued under the Indenture are direct, unsecured obligations of the Company and will mature on October 1, 2010. The 10 3/4% Notes rank on parity with all other unsecured, unsubordinated
indebtedness of the Company. 
 The 10 3/4% Notes will bear interest as set forth on the face hereof.

 The
10 3/4% Notes are not redeemable prior to their
Stated Maturity. 
 The 10 3/4% Notes are not entitled to any sinking fund. 

If an Event of Default with respect to the 10 3/4% Notes shall occur and be continuing, the principal of the 10 3/4% Notes 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 aggregate 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 10 3/4% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 10 3/4% Note 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 10 3/4% Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this 10 3/4% Note 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 the 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 10 3/4% Note for the enforcement of any payment of principal hereof or
interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 10 3/4% Note or of the Indenture shall alter or impair the
obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 10 3/4% Note at the times, place(s) and rates, and in the coin or currency, herein prescribed. 

[If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 10 3/4% Note is registrable in the Security Register, upon
surrender of this 10 3/4% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for a
like aggregate principal amount, will be issued to the designated transferee or transferees. 

The 10 3/4% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the 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. 
 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 transfer tax or other similar governmental charge payable in connection therewith. 

Prior to due presentment of this
10 3/4% Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
10 3/4% Note is registered as the owner hereof for
all purposes, whether or not this 10 3/4% Note be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 

THIS 10 3/4% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 

Except as otherwise expressly provided herein, all terms used in this 10 3/4% Note but not otherwise defined herein shall have the meanings
assigned to them in the Indenture.

 [REVERSE OF 9 5/8% SENIOR NOTE DUE 2012] 

EL PASO CORPORATION 
 9 
5/8% Senior Note due 2012 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original
Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as
trustee (the “ Trustee ,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This note is one of the notes in a series designated as 9 5/8% Senior Notes due 2012 of the Company (hereinafter called the
“ 9 5/8% Notes ”), issued under the Original Indenture, which 9 5/8% Notes are limited in aggregate principal amount to $150,000,000. 
 Except as provided in Sections 1006 and 1007 of the Original Indenture, neither the Indenture nor the
9 5/8% Notes limit or otherwise restrict the amount
of indebtedness which may be incurred or other securities which may be issued by the Company. The 9 5/8% Notes issued under the Indenture are direct, unsecured obligations of the Company and will mature on May 15, 2012. The 9 5/8% Notes rank on parity with all other unsecured, unsubordinated
indebtedness of the Company. 
 The 9 5/8% Notes will bear interest as set forth on the face hereof.

 The
9 5/8% Notes are not redeemable prior to their
Stated Maturity. 
 The 9 5/8% Notes are not entitled to any sinking fund. 

If an Event of Default with respect to the 9 5/8% Notes shall occur and be continuing, the principal of the 9 5/8% Notes 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 aggregate 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 9 5/8% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 9 5/8% Note 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 9 5/8% Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this 9 5/8% Note 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 the 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 9 5/8% Note for the enforcement of any payment of principal hereof or
interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 9 5/8% Note or of the Indenture shall alter or impair the
obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this
9 5/8% Note at the times, place(s) and rates, and in
the coin or currency, herein prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.]

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 9 5/8% Note is registrable in the Security Register, upon
surrender of this 9 5/8% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for a
like aggregate principal amount, will be issued to the designated transferee or transferees. 

The 9 5/8% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the 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. 
 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 transfer tax or other similar governmental charge payable in connection therewith. 

Prior to due presentment of this
9 5/8% Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
9 5/8% Note is registered as the owner hereof for
all purposes, whether or not this 9 5/8% Note be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 

THIS 9 5/8% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 

Except as otherwise expressly provided herein, all terms used in this 9 5/8% Note but not otherwise defined herein shall have the meanings
assigned to them in the Indenture. 
 [If a Transfer Restricted Security, insert—The
Holder of this 9 5/8% Note is entitled to the
benefits of the Registration Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement”), by and among the Company and the Dealer Managers named therein, and such Holders shall also have certain
obligations to indemnify the Company under certain circumstances, all as more fully set forth in the Registration Rights Agreement.]

 EL PASO CORPORATION (the “Company,” which term includes any
successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to [                    ] [ if a
Global Security, insert — Cede & Co., as nominee for The Depository Trust Company], or registered assigns, the principal sum of
                     [ if a Global Security, insert — , or such other principal amount as shall be set forth in the Schedule of Increases
or Decreases attached hereto], on the Stated Maturity Date specified above (or any Redemption Date or Repayment Date, each as defined on the reverse hereof) (each such Stated Maturity Date, Redemption Date or Repayment Date being hereinafter
referred to as the “ Maturity ” with respect to the principal repayable on such date) and to pay interest thereon, at the Interest Rate per annum specified above, until the principal hereof is paid or duly made available for
payment. The Company will pay interest in arrears on each Interest Payment Date, if any, specified above (each, an “ Interest Payment Date ”), commencing with the first Interest Payment Date next succeeding the Issue Date specified
above, and at Maturity; provided , however , that the first payment of interest on any 7.75% Note (as defined on the reverse hereof) originally issued between a record date and an Interest Payment Date will be made on the first
Interest Payment Date following the next succeeding record date to the Holder of the 7.75% Note on such succeeding record date. Unless otherwise specified on the face hereof, interest on this 7.75% Note will be computed on the basis of a 360-day
year of twelve 30-day months. 
 Notwithstanding the foregoing, if an Addendum is attached hereto or “Other
Provisions” apply to this 7.75% Note as specified above, this 7.75% Note shall be modified by and subject to the terms set forth in such Addendum or such “Other Provisions.” 

Interest on this 7.75% Note will accrue from, and including, October 15, 2005 (or from and including the most recent date to which
interest has been paid or duly provided for) to, but excluding, the applicable Interest Payment Date or the Maturity, as the case may be. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, subject
to certain exceptions described herein, be paid to the person in whose name this 7.75% Note (or one or more predecessor 7.75% Notes) is registered at the close of business on the Regular Record Date (whether or not a Business Day, as defined below)
immediately preceding such Interest Payment Date; provided , however , that interest payable at Maturity will be payable to the person to whom the principal hereof and premium, if any, hereon shall be payable. 

“Business Day,” as used herein, means each Monday, Tuesday, Wednesday, Thursday and Friday that is neither a legal
holiday nor a day on which banking institutions are generally authorized or obligated by law or executive order to close in The City of New York or any other place or places where the principal of (and premium, if any) and interest on the 7.75%
Notes is payable and also, with respect to 7.75% Notes denominated in a Specified Currency other than U.S. dollars, in the Principal Financial Center (as defined below) of the country issuing the Specified Currency. 

Payment of principal, premium, if any, and interest in respect of this 7.75% Note due at Maturity to be made in U.S. dollars will be made in immediately
available funds upon presentation and surrender of this 7.75% Note (and, with respect to any applicable repayment of this 7.75% Note, a duly completed election form as contemplated on the reverse hereof) at the office of the Paying Agent in The City
of New York, or at such other places as may be designated by the Company; provided that the 7.75% Note is presented to the Paying Agent in time for the Paying Agent to make such payments in such funds in accordance with its normal procedures. Unless
otherwise specified above, if any payment at Maturity is to be made in a Specified Currency other than U.S. dollars as set forth below, such payment will be made by wire transfer of immediately available funds to an account with a bank located in
the Principal Financial Center of the country issuing the Specified Currency or other jurisdiction acceptable to the Company and the Paying Agent as shall have been designated by the Holder hereof at least five Business Days prior to Maturity,
provided that such bank has appropriate facilities therefor and that this 7.75% Note (and, if applicable, a duly completed election form) is presented and surrendered at the aforementioned office of the Paying Agent in time for the Paying Agent to
make such payments in such funds in accordance with its normal procedures. (Such designation with respect to a payment in other than U.S. dollars shall be made by filing the appropriate information with the Paying Agent at the office of the Paying
Agent in The City of New York, and, unless revoked, any such designation made with respect to this 7.75% Note by its registered Holder will remain in effect with respect to any further payments with respect to this 7.75% Note payable to its Holder.
If such a payment with respect to this 7.75% Note cannot be made by wire transfer because the required designation has not been received by the Paying Agent on or before the requisite date or for any other reason, a notice will be mailed to the
Holder of this 7.75% Note at its registered address requesting a designation pursuant to which such wire transfer can be made and, upon the Paying Agent’s receipt of such a 

 
designation, such payment will be made within five Business Days of such receipt.) The Company will pay any administrative costs imposed by banks in connection with making payments by wire
transfer, but any tax, assessment or governmental charge imposed upon payments will be borne by the Holder of this 7.75% Note. 

If this 7.75% Note is denominated in and principal, premium, if any, and interest is payable in U.S. dollars, principal (and premium, if
any) and any interest will be payable at the principal corporate trust office of the Trustee in The City of New York, or at such other places as may be designated by the Company, provided that the Company, at its option, may pay interest other than
interest due at Maturity by check mailed or delivered to the address of the person entitled thereto as such address appears in the Security Register, or by wire transfer of immediately available funds to an account designated by such person if
appropriate wire transfer instructions have been received in writing by the Paying Agent not less than 10 calendar days prior to such Interest Payment Date. Any such wire transfer instructions received by the Paying Agent shall remain in effect
until revoked by such Holder. Unless otherwise specified above, any interest on this 7.75% Note (other than interest at Maturity) that is payable in a Specified Currency other than U.S. dollars will be paid by mailing a check or draft in the
Specified Currency drawn on an account at a bank outside of the United States. 
 If any Interest Payment Date, Redemption Date,
Optional Repayment Date or Stated Maturity falls on a day that is not a Business Day, the required payment of principal, premium, if any, and/or interest need not be made on such day, but may be made on the next succeeding Business Day with the same
force and effect as if made on the date such payment was due, and no interest shall accrue with respect to such payment for the period from and after such Interest Payment Date, Redemption Date, Optional Repayment Date or Stated Maturity, as the
case may be, to the date of such payment on the next succeeding Business Day. 
 “Principal Financial Center”
means the capital city of the country issuing the Specified Currency in respect of which payment on the 7.75% Notes is to be made, except that with respect to U.S. dollars, Australian dollars, Deutsche marks, Dutch guilders, Italian lire, Swiss
francs and ECUs, the Principal Financial Center shall be The City of New York, Sydney, Frankfurt, Amsterdam, Milan, Zurich and Luxembourg, respectively. 
 The Company is obligated to make payment of principal, premium, if any, and interest in respect of this 7.75% Note in the Specified Currency (or, if the Specified Currency is not at the time of such
payment legal tender for the payment of public and private debts, in such other coin or currency of the country which issued the Specified Currency as at the time of such payment is legal tender for the payment of such debts). If the Specified
Currency is other than U.S. dollars, any such amounts so payable by the Company, at the option of the Company, may be converted by the Exchange Rate Agent specified above into U.S. dollars for payment to the Holder of this 7.75% Note;
provided , however , that, if specified above under “Other Provisions,” the Holder of this 7.75% Note may elect to receive such amounts in U.S. dollars or in the Specified Currency pursuant to the provisions set forth below.

 Payments of principal of, premium, if any, and interest on any 7.75% Note denominated in a Specified Currency other than U.S.
dollars (a “ Foreign Currency Note ”) will be made in U.S. dollars if the registered Holder of such 7.75% Note on the relevant Regular Record Date, or at Maturity, as the case may be, has transmitted a written request for such
payment in U.S. dollars to the Paying Agent at the office of the Paying Agent in The City of New York on or before such Regular Record Date, or the date 15 days before Maturity, as the case may be. Such request may be in writing (mailed or hand
delivered) or sent by cable, telex, or other form of facsimile transmission. Any such request made for any 7.75% Note by a registered Holder will remain in effect for any further payments of principal of, premium, if any, and interest on such 7.75%
Note payable to such Holder, unless such request is revoked on or before the relevant Regular Record Date or the date 15 days before Maturity, as the case may be. 
 Any U.S. dollar amount to be received by a Holder of a Foreign Currency Note will be based on the highest bid quotation in The City of New York received by the Exchange Rate Agent at approximately 11:00
a.m. New York City time on the second Business Day preceding the applicable payment date from three recognized foreign exchange dealers (one of whom may be the Exchange Rate Agent) selected by the Exchange Rate Agent and approved by the Company for
purchase by the quoting dealer of the Specified Currency for U.S. dollars for settlement on such payment date in the aggregate amount of the Specified Currency payable to all Holders of Foreign Currency Notes scheduled to receive U.S. dollar
payments and at which the applicable dealer commits to execute a contract. All currency exchange costs will be borne by the Holder of such Foreign Currency Note by deductions from such payments. If three such bid quotations are not available on the
second Business Day prior to the applicable payment date, payments may be made in the Specified Currency. 

 A Holder of a Foreign Currency Note may elect to receive payment of the principal of and
premium, if any, and interest on such 7.75% Note in the Specified Currency by submitting a written request for such payment to the Trustee at its Corporate Trust Office in The City of New York on or prior to the applicable Regular Record Date or at
least 15 calendar days prior to Maturity, as the case may be. Such written request may be may be in writing (mailed or hand delivered) or sent by cable, telex, or other form of facsimile transmission. A Holder of a Foreign Currency Note may elect to
receive payment in the applicable Specified Currency for all such principal, premium, if any, and interest payments and need not file a separate election for each payment. Such election will remain in effect until revoked by written notice to the
Trustee, but written notice of any such revocation must be received by the Trustee on or prior to the applicable Regular Record Date or at least 15 calendar days prior to Maturity, as the case may be. 

If the principal of, and premium, if any, or interest on any 7.75% Note is payable in a Specified Currency other than U.S. dollars and
such Specified Currency is not available to the Company for making payments thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company, the Company will be entitled to satisfy its obligations to the
Holder of such 7.75% Note by making such payment (including any such payment at Maturity) in U.S. dollars on the basis of the methodology described in the second preceding paragraph. 

All determinations referred to above made by the Exchange Rate Agent shall be at its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and binding on the Holder of this 7.75% Note. 
 Reference is hereby made to the
further provisions of this 7.75% Note set forth on the reverse hereof and, if so specified above, in the Addendum hereto, which further provisions shall have the same force and effect as if set forth on the face hereof. 

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this 7.75% Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [REVERSE OF 7.75% SENIOR NOTE DUE 2032] 

EL PASO CORPORATION 
 7.75% Senior Note due 2032 
 (Fixed Rate) 

This note 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 (the “ Original Indenture ”), as previously supplemented and as further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the
“ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC Bank USA, National Association, a national banking association, as successor-in-interest
to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This note is one of the notes in a series
designated as 7.75% Senior Notes due 2032 of the Company (hereinafter called the “ 7.75% Notes ”), issued under the Original Indenture, which 7.75% Notes are limited in aggregate principal amount to $150,000,000. All terms used but
not defined in this 7.75% Note or specified on the face hereof or in an Addendum hereto shall have the meanings assigned to such terms in the Indenture. 
 This 7.75% Note is issuable only in registered form without coupons. 7.75% Notes denominated in U.S. dollars will be initially issued in denominations of $1,000 and integral multiples thereof, and 7.75%
Notes denominated in other than U.S. dollars will be initially issued in denominations of the equivalent of $1,000 in the Specified Currency (rounded down to an integral multiple of 1,000 units of such Specified Currency), at the noon buying rate
for cable transfers in The City of New York of such Specified Currency (the “ Exchange Rate ”) on the Business Day next preceding the date on which the Company accepts the offer to purchase such 7.75% Note. 

This 7.75% Note will not be subject to any sinking fund and, unless otherwise provided on the face hereof in accordance with the
provisions of the following two paragraphs, will be redeemable but not repayable prior to the Stated Maturity Date. 
 The
Company has the option, if specified on the face hereof, to reset the interest rate on the date or dates specified on the face hereof as Optional Reset Dates. If the Company elects to reset the interest rate, the Holder will have the option to elect
repayment of this 7.75% Note by the Company on any Optional Reset Date at a price equal to the aggregate principal amount thereof outstanding on, plus any interest accrued to, such Optional Reset Date (or, for an Original Issue Discount Note, as
specified below). In order for this 7.75% Note to be so repaid on an Optional Reset Date, the Holder must follow the procedures specified below in connection with optional repayment, except that (i) the period for delivery of such 7.75% Note or
notification to the Trustee will be at least 25 but not more than 35 days prior to such Optional Reset Date and (ii) a Holder who has tendered a 7.75% Note for repayment pursuant to a Reset Notice (as defined below) may, by written notice to
the Trustee, revoke any such tender until the close of business on the tenth day prior to such Optional Reset Date. 
 The
Company may exercise the option to reset the interest rate on this 7.75% Note by notifying the Trustee (the “ Company’s Notice of Reset ”) of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date
for such 7.75% Note. After receipt of the Company’s Notice of Reset, and not later than 40 days prior to such Optional Reset Date, the Trustee for this 7.75% Note will mail, first class, postage prepaid, or deliver to the Holder a notice (the
“ Reset Notice ”). Based on information provided to the Trustee by the Company in the Company’s Notice of Reset, the Reset Notice will indicate whether the Company has elected to reset the interest rate and, if so,
(i) such new interest rate and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or, if there is no such next Optional Reset Date, to the Stated Maturity Date of
this 7.75% Note (each such period, a “ Subsequent Interest Period ”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during such Subsequent
Interest Period. Notwithstanding the foregoing, the Company may, at its option, revoke the interest rate as provided for in the Reset Notice, and establish a higher interest rate than the interest rate provided for in the relevant Reset 

 
Notice for the Subsequent Interest Period commencing on such Optional Reset Date, by notifying the Trustee of such revocation and such higher interest rate and causing the Trustee to mail or
deliver to the Holder, not later than 20 days prior to an Optional Reset Date for this 7.75% Note (or, if such day is not a Business Day, on the immediately succeeding Business Day), notice of such higher interest rate. Such notice will be
irrevocable. The Company must notify the Trustee of its intention to revoke such Reset Notice at least 25 days prior to such Optional Reset Date. If the interest rate of this 7.75% Note is reset on an Optional Reset Date and the Holder has not
tendered this 7.75% Note for repayment (or has validly revoked any such tender) in accordance with the applicable procedures this 7.75% Note will bear such higher interest rate for the Subsequent Interest Period. 

As specified on the face hereof, this 7.75% Note will be subject to redemption at the option of the Company on any date on and after the
Redemption Commencement Date specified on the face hereof, in whole or from time to time in part, at the Make-Whole Price (as defined below), on notice given no more than 60 nor less than 30 calendar days prior to the date of redemption (the
“ Redemption Date ”) and in accordance with the provisions of the Indenture. “ Make-Whole Price ” means an amount equal to the greater of (i) 100% of the principal amount of this 7.75% Note to be redeemed 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 (not including any portion of such payments of interest accrued as of the Redemption
Date) discounted back to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 25 basis points, plus, in the case of both (i) and (ii), accrued and
unpaid interest to the Redemption Date. Unless the Company defaults in payment of the Make-Whole Price, on and after the Redemption Date, interest will cease to accrue on the principal amount of this 7.75% Note to be redeemed. In the event of
redemption of the 7.75% Note in part only, a new 7.75% Note of like tenor for the unredeemed portion hereof and otherwise having the same terms as this 7.75% Note shall be issued in the name of the Holder hereof upon the presentation and surrender
hereof. 
 “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 this 7.75% Note 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 this 7.75% Note. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date, (i) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains
fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation
with the Company. 
 “Reference Treasury Dealer” means (i) Banc of America Securities LLC; ABN AMRO
Incorporated; BNP Paribas Securities Corp.; Credit Lyonnais Securities (USA) Inc. and J.P. Morgan Securities Inc. and their respective successors; provided , however , that if any of the foregoing shall not be a primary U.S. government
securities dealer in New York City (a “ Primary Treasury Dealer ”), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any two other Primary Treasury Dealers the Company selects. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.
on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means, with respect to any
Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication that
is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,”
for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after 
 the
Stated Maturity, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding
to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield

 
to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price
for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

Notwithstanding Section 1104 of the Indenture, the notice of redemption with respect to the foregoing redemption need not set forth
the Make-Whole Price but only the manner of calculation thereof. The Company shall notify the Trustee of the Make-Whole Price with respect to the foregoing redemption promptly after the calculation thereof, and the Trustee shall not be responsible
for such calculation. 
 If specified on the face hereof, this 7.75% Note (unless this 7.75% Note is an Original Issue Discount
Note) will be subject to repayment by the Company at the option of the Holder hereof on the Optional Repayment Date(s), if any, specified on the face hereof, in whole or in part in increments of U.S. $1,000 (or 1,000 units of the Specified
Currency), at the Optional Repayment Price stated on the face hereof, which is a price equal to 100% of the unpaid principal amount to be repaid, together with any accrued and unpaid interest and premium payable thereon to the specified Optional
Repayment Date (each, a “ Repayment Date ”). For this 7.75% Note to be repaid, the Company must receive at its offices or agencies for that purpose in The City of New York not more than 60 nor less than 30 calendar days prior to the
Repayment Date, (i) the 7.75% Note with the form herein entitled “Option to Elect Repayment” duly completed or (ii) a telegram, telex, facsimile transmission or letter from a member of a national securities exchange or the
National Association of Securities Dealers, Inc. or a commercial bank or a trust company in the United States of America setting forth the name of the holder of the 7.75% Note, the principal amount of the 7.75% Note, the amount of the 7.75% Note to
be repaid, a statement that the option to elect repayment is being exercised thereby and a guarantee that the 7.75% Note to be repaid with the form entitled “Option to Elect Repayment” herein duly completed will be received by the Company
not later than five Business Days after the date of such telegram, telex, facsimile transmission or letter and such 7.75% Note and form duly completed are received by the Company by such fifth Business Day. Exercise of such repayment option by the
Holder hereof will be irrevocable. In the event of repayment of this 7.75% Note in part only, a new 7.75% Note of like tenor for the unrepaid portion hereof and otherwise having the same terms as this 7.75% Note shall be issued in the name of the
Holder hereof upon the presentation and surrender hereof. All questions as to the validity, eligibility (including time of receipt) and acceptance of this 7.75% Note for repayment will be determined by the Company, whose determination will be final
and binding. 
 If this 7.75% Note is an Original Issue Discount Note as specified on the face hereof, the amount payable to the
Holder of this 7.75% Note in the event of redemption, repayment or acceleration of Maturity will be equal to (i) the Amortized Face Amount (as defined below) as of the date of such event, plus (ii) with respect to any redemption, the
Initial Redemption Percentage specified on the face hereof (as adjusted by the Annual Redemption Percentage Reduction, if any, specified on the face hereof) minus 100% multiplied by the Issue Price specified on the face hereof, net of any portion of
such Issue Price which has been paid prior to the Redemption Date, or the portion of the Issue Price (or the net amount) proportionate to the portion of the unpaid principal amount to be redeemed, plus (iii) any accrued interest to the date of
such event, the payment of which would constitute qualified stated interest payments within the meaning of Treasury Regulation 1.1273-1(c) under the Internal Revenue Code of 1986, as amended (the “ Code ”). The accrued interest
described in clause (iii) above will be computed on the basis of a 360-day year of twelve 30-day months, compounded semiannually. The “Amortized face Amount” means an amount equal to (i) the Issue Price plus (ii) the
aggregate portions of the original issue discount (the excess of the amounts considered as part of the “stated redemption price at maturity” of this 7.75% Note within the meaning of Section 1273(a)(2) of the Code, whether denominated
as principal or interest, over the Issue Price) which shall theretofore have accrued pursuant to Section 1272 of the Code (without regard to Section 1272(a)(7) of the Code) from the Original Issue Date to the date of determination, minus
(iii) any amount considered as part of the “stated redemption price at maturity” of this 7.75% Note which has been paid from the Original Issue Date to the date of determination. 

If the Maturity of an Original Issue Discount Note that bears no interest falls on a day that is not a Business Day with respect to such
Original Issue Discount Note, the payment due at Maturity will be made on the following day that is a Business Day with the same force and effect as if it were made on the date such payment was due, and no interest shall accrue on the amount so
payable for the period from and after Maturity. 
 Unless otherwise stated on the face hereof, each 7.75% Note will mature at
the Stated Maturity Date of such 7.75% Note. If stated on the face hereof, the Company has the option to extend the Stated Maturity Date of such 7.75% Note for one or more periods of whole years from one to five (each an “ Extension
Period ”) up to but not beyond the date (the “ Final Maturity ”) set forth on the face hereof. 

 The Company may exercise such option with respect to a 7.75% Note by notifying the Trustee
(the “ Company’s Notice of Extension ”) of such exercise at least 50 but not more than 60 days prior to the old Stated Maturity Date for such 7.75% Note. After receipt of the Company’s Notice of Extension, and not later
than 40 days prior to the old Stated Maturity Date of such 7.75% Note, the Trustee for such 7.75% Note will mail, first class, postage prepaid, or deliver to the Holder thereof a notice (the “ Extension Notice ”). Based on
information provided to the Trustee in the Company’s Notice of Extension, the Extension Notice will set forth (i) the election of the Company to extend the Stated Maturity Date of such 7.75% Note; (ii) the new Stated Maturity Date;
(iii) the interest rate applicable to the Extension Period; and (iv) the provisions, if any, for redemption during the Extension Period, including the date or dates on which or the period or periods during which and the price or prices at
which such redemption may occur during the Extension Period. Upon the mailing or delivery by such Trustee of an Extension Notice to the Holder of a 7.75% Note, the Stated Maturity Date of such 7.75% Note shall be extended automatically, and, except
as modified by the Extension Notice and as described in the next paragraph, such 7.75% Note will have the same terms as prior to the mailing or delivering of such Extension Notice. 

Notwithstanding the foregoing, not later than 20 days prior to the old Stated Maturity Date of such 7.75% Note (or, if such day is not a
Business Day, on the immediately succeeding Business Day), the Company may, at its option, revoke the interest rate provided for in the Extension Notice for such 7.75% Note and establish a higher interest rate for the Extension Period, by notifying
the Trustee of such revocation and such higher interest rate and causing the Trustee for such 7.75% Note to mail, first class, postage prepaid, or deliver notice of such higher interest rate to the Holder of such 7.75% Note. Such notice will be
irrevocable. All 7.75% Notes with respect to which the Stated Maturity Date is extended will bear such higher interest rate for the Extension Period, whether or not tendered for repayment. 

If the Company extends the Stated Maturity Date of this 7.75% Note, the Holder of this 7.75% Note will have the option to elect repayment
of such 7.75% Note by the Company on the old Stated Maturity Date at a price equal to the aggregate principal amount thereof outstanding on, plus interest accrued to, such date or, for an Original Issue Discount Note, as described above. In order
for a 7.75% Note to be repaid on the old Stated Maturity Date once the Company has extended the Stated Maturity Date thereof, the Holder thereof must follow the procedures applicable to optional repayment set forth above, except that (i) the
period for delivery of this 7.75% Note or notification to the Trustee for this 7.75% Note will be at least 25 but not more than 35 days prior to the old Stated Maturity Date and (ii) a Holder who has tendered a 7.75% Note for repayment pursuant
to an Extension Notice may, by written notice to the Trustee, revoke any such tender for repayment until the close of business on the tenth day before the old Stated Maturity Date. 

If an Event of Default, as defined in the Indenture, shall occur and be continuing, the principal of the 7.75% Notes may be declared due
and payable in the manner and with the effect provided in the Indenture. The Indenture contains provisions setting forth certain conditions to the institution of proceedings by Holders of 7.75% Notes with respect to the Indenture or for any remedy
under the Indenture. 
 The Indenture contains provisions for discharge of the 7.75% Notes and for defeasance of (i) the
entire indebtedness of the 7.75% Notes or (ii) certain covenants and Events of Default with respect to the 7.75% Notes, in each case upon compliance with certain conditions set forth therein, which provisions apply to the 7.75% Notes.

 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 a series of Securities at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of all series of
Securities (acting as one class) at the time outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the outstanding Securities of all affected
series, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain restrictive provisions of the Indenture. Furthermore, provisions in the Indenture permit the Holders of not less than a majority of
the aggregate principal amount of any series, in certain instances, to waive, on behalf of all of the Holders of Securities of such series, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this 7.75% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 7.75% Note and other 7.75% Notes 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 the 7.75% Note. 

 No reference herein to the Indenture and no provision of this 7.75% Note or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay principal, premium, if any, and interest in respect of this 7.75% Note at the times, places and rate or formula, and in the coin or currency, herein
prescribed. 
 As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of
this 7.75% Note is registrable in the Security Register of the Company upon surrender of this 7.75% Note for registration of transfer at the office or agency of the Company in any place where this 7.75% Note is payable, 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 by his attorney duly authorized in writing, and thereupon one or more new 7.75% Notes, of
authorized denominations and for the same aggregate principal amount and having the same terms and conditions, will be issued to the designated transferee or transferees. As provided in the Indenture and subject to certain limitations therein and
herein set forth, this 7.75% Note is exchangeable for a like aggregate principal amount of 7.75% Notes of different authorized denominations but otherwise having the same terms and conditions, as requested by the Holder hereof surrendering the same.
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. 

The Indenture provides that no recourse may be taken, directly or indirectly, against any incorporator, subscriber to the capital stock,
stockholder, officer, director or employee of the Company or of any predecessor or successor of the Company with respect to the Company’s obligations on the 7.75% Notes or the obligations of the Company under the Indenture. Each Holder by
accepting a 7.75% Note waives all such recourse. 
 Prior to due presentment of this 7.75% Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 7.75% Note is registered as the owner thereof for all purposes, whether or not this 7.75% Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary. 
 THIS 7.75% NOTE SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 [If a Transfer Restricted Security, insert—The Holder of
this 7.75% Note is entitled to the benefits of the Registration Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement ”), by and among the Company and the Dealer Managers named therein, and such
Holders shall also have certain obligations to indemnify the Company under certain circumstances, all as more fully set forth in the Registration Rights Agreement.]

 [REVERSE OF 7.42% SENIOR NOTE DUE 2037] 

EL PASO CORPORATION 
 7.42% Senior Note due 2037 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further
supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC
Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are,
and are to be, authenticated and delivered. This note is one of the notes in a series designated as 7.42% Senior Notes due 2037 of the Company (hereinafter called the “ 7.42% Notes ”), issued under the Original Indenture, which
7.42% Notes are limited in aggregate principal amount to $200,000,000. 
 Except as provided in Sections 1006 and 1007 of the
Original Indenture, neither the Indenture nor the 7.42% Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 7.42% Notes issued under the Indenture are direct,
unsecured obligations of the Company and will mature on February 15, 2037. The 7.42% Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 

The 7.42% Notes will bear interest as set forth on the face hereof. 

The 7.42% Notes are not redeemable prior to their Stated Maturity. 

The 7.42% Notes are not entitled to any sinking fund. 
 If an Event of Default with respect to the 7.42% Notes shall occur and be continuing, the principal of the 7.42% Notes 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 aggregate 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 7.42%
Note shall be conclusive and binding upon such Holder and upon all future Holders of this 7.42% Note 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 7.42% Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of
this 7.42% Note 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 the 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 7.42% Note for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

 No reference herein to the Indenture and no provision of this 7.42% Note or of the Indenture
shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 7.42% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 7.42% Note is registrable in the
Security Register, upon surrender of this 7.42% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees. 
 The 7.42% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the 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.

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 7.42% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 7.42% Note is registered as the owner hereof for all purposes, whether or not
this 7.42% Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 
 THIS 7.42% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Except as otherwise expressly provided herein, all terms used in this 7.42% Note but not otherwise defined herein shall have the meanings assigned to them in the Indenture. 

[If a Transfer Restricted Security, insert—The Holder of this 7.42% Note is entitled to the benefits of the Registration
Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement ”), by and among the Company and the Dealer Managers named therein, and such Holders shall also have certain obligations to indemnify the
Company under certain circumstances, all as more fully set forth in the Registration Rights Agreement.]

 [REVERSE OF 6.95% SENIOR NOTE DUE 2028] 

EL PASO CORPORATION 
 6.95% Senior Note due 2028 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further
supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC
Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are,
and are to be, authenticated and delivered. This note is one of the notes in a series designated as 6.95% Senior Notes due 2028 of the Company (hereinafter called the “ 6.95% Notes ”), issued under the Original Indenture, which
6.95% Notes are limited in aggregate principal amount to $200,000,000. 
 Except as provided in Sections 1006 and 1007 of the
Original Indenture, neither the Indenture nor the 6.95% Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 6.95% Notes issued under the Indenture are direct,
unsecured obligations of the Company and will mature on June 1, 2028. The 6.95% Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 
 The 6.95% Notes will bear interest as set forth on the face hereof. 
 The 6.95%
Notes are not redeemable prior to their Stated Maturity. 
 The 6.95% Notes are not entitled to any sinking fund. 

If an Event of Default with respect to the 6.95% Notes shall occur and be continuing, the principal of the 6.95% Notes 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 aggregate 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 6.95% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 6.95% Note 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 6.95% Note. 
 As provided in and subject to
the provisions of the Indenture, the Holder of this 6.95% Note 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 the 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 6.95% Note for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 6.95% Note or of the Indenture
shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 6.95% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 6.95% Note is registrable in the
Security Register, upon surrender of this 6.95% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees. 
 The 6.95% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the 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.

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 6.95% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 6.95% Note is registered as the owner hereof for all purposes, whether or not
this 6.95% Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 
 THIS 6.95% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Except as otherwise expressly provided herein, all terms used in this 6.95% Note but not otherwise defined herein shall have the meanings assigned to them in the Indenture. 

[If a Transfer Restricted Security, insert—The Holder of this 6.95% Note is entitled to the benefits of the Registration
Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement ”), by and among the Company and the Dealer Managers named therein, and such Holders shall also have certain obligations to indemnify the
Company under certain circumstances, all as more fully set forth in the Registration Rights Agreement.]

 [REVERSE OF 6.375% SENIOR NOTE DUE 2009] 

EL PASO CORPORATION 
 6.375% Senior Note due 2009 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as
further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and
HSBC Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities
are, and are to be, authenticated and delivered. This note is one of the notes in a series designated as 6.375% Senior Notes due 2009 of the Company (hereinafter called the “ 6.375% Notes ”), issued under the Original Indenture,
which 6.375% Notes are limited in aggregate principal amount to $200,000,000. 
 Except as provided in Sections 1006 and 1007 of
the Original Indenture, neither the Indenture nor the 6.375% Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 6.375% Notes issued under the Indenture are
direct, unsecured obligations of the Company and will mature on February 1, 2009. The 6.375% Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 

The 6.375% Notes will bear interest as set forth on the face hereof. 

The 6.375% Notes are not redeemable prior to their Stated Maturity. 

The 6.375% Notes are not entitled to any sinking fund. 
 If an Event of Default with respect to the 6.375% Notes shall occur and be continuing, the principal of the 6.375% Notes 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 aggregate 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 6.375%
Note shall be conclusive and binding upon such Holder and upon all future Holders of this 6.375% Note 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 6.375% Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of
this 6.375% Note 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 the 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 6.375% Note for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 6.375% Note or of the
Indenture shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 6.375% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 6.375% Note is registrable in the
Security Register, upon surrender of this 6.375% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees. 
 The 6.375% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the 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.

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 6.375% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 6.375% Note is registered as the owner hereof for all purposes, whether or not
this 6.375% Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 
 THIS 6.375% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Except as otherwise expressly provided herein, all terms used in this 6.375% Note but not otherwise defined herein shall have the meanings assigned to them in the Indenture. 

[If a Transfer Restricted Security, insert—The Holder of this 6.375% Note is entitled to the benefits of the Registration
Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement “), by and among the Company and the Dealer Managers named therein, and such Holders shall also have certain obligations to indemnify the

 [REVERSE OF 7.625% SENIOR NOTE DUE 2008] 

EL PASO CORPORATION 
 7.625% Senior Note due 2008 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as
further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and
HSBC Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities
are, and are to be, authenticated and delivered. This note is one of the notes in a series designated as 7.625% Senior Notes due 2008 of the Company (hereinafter called the “ 7.625% Notes ”), issued under the Original Indenture,
which 7.625% Notes are limited in aggregate principal amount to $215,000,000. 
 Except as provided in Sections 1006 and 1007 of
the Original Indenture, neither the Indenture nor the 7.625% Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 7.625% Notes issued under the Indenture are
direct, unsecured obligations of the Company and will mature on September 1, 2008. The 7.625% Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 

The 7.625% Notes will bear interest as set forth on the face hereof. 

The 7.625% Notes are not redeemable prior to their Stated Maturity. 

The 7.625% Notes are not entitled to any sinking fund. 
 If an Event of Default with respect to the 7.625% Notes shall occur and be continuing, the principal of the 7.625% Notes 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 aggregate 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 7.625%
Note shall be conclusive and binding upon such Holder and upon all future Holders of this 7.625% Note 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 7.625% Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of
this 7.625% Note 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 the 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 7.625% Note for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 7.625% Note or of the
Indenture shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 7.625% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 7.625% Note is registrable in the
Security Register, upon surrender of this 7.625% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees. 
 The 7.625% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the 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.

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 7.625% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 7.625% Note is registered as the owner hereof for all purposes, whether or not
this 7.625% Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 
 THIS 7.625% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Except as otherwise expressly provided herein, all terms used in this 7.625% Note but not otherwise defined herein shall have the meanings assigned to them in the Indenture. 

[If a Transfer Restricted Security, insert—The Holder of this 7.625% Note is entitled to the benefits of the Registration
Rights Agreement, dated as of December 28, 2005 (the “ Registration Rights Agreement ”), by and among the Company and the Dealer Managers named therein, and such Holders shall also have certain obligations to indemnify the
Company under certain circumstances, all as more fully set forth in the Registration Rights Agreement.]

 [REVERSE OF 6.50% SENIOR NOTE DUE 2006] 

EL PASO CORPORATION 
 6.50% Senior Note due 2006 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further
supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC
Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as trustee (the “ Trustee ,” which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are,
and are to be, authenticated and delivered. This note is one of the notes in a series designated as 6.50% Senior Notes due 2006 of the Company (hereinafter called the “ 6.50% Notes ”), issued under the Original Indenture, which
6.50% Notes are limited in aggregate principal amount to $109,500,000. 
 Except as provided in Sections 1006 and 1007 of the
Original Indenture, neither the Indenture nor the 6.50% Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The 6.50% Notes issued under the Indenture are direct,
unsecured obligations of the Company and will mature on May 15, 2006. The 6.50% Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 
 The 6.50% Notes will bear interest as set forth on the face hereof. 
 The 6.50%
Notes are not redeemable prior to their Stated Maturity. 
 The 6.50% Notes are not entitled to any sinking fund. 

If an Event of Default with respect to the 6.50% Notes shall occur and be continuing, the principal of the 6.50% Notes 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 aggregate 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 6.50% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 6.50% Note 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 6.50% Note. 
 As provided in and subject to
the provisions of the Indenture, the Holder of this 6.50% Note 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 the 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 6.50% Note for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

 No reference herein to the Indenture and no provision of this 6.50% Note or of the Indenture
shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 6.50% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.] 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 6.50% Note is registrable in the
Security Register, upon surrender of this 6.50% Note 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for a like aggregate principal amount, will be issued to the designated transferee or transferees. 
 The 6.50% Notes are issuable only in registered forms without coupons, in minimum denominations of $1,000 or any integral multiple thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the 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.

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 6.50% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 6.50% Note is registered as the owner hereof for all purposes, whether or not

 No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or for any claim based thereon or otherwise in respect thereof, or in
any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person, either directly
or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly
waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 
 THIS 6.50% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Except as otherwise expressly provided herein, all terms used in this 6.50% Note but not otherwise defined herein shall have the meanings assigned to them in the Indenture.

unless the Company defaults in paying the Redemption Price therefor, any 6.70% Note submitted for redemption pursuant to the Redemption Right shall cease to accrue interest after the Redemption Date; 

	 	(f)	that any Holder electing to have a 6.70% Note redeemed pursuant to the Redemption Right will be required to surrender the 6.70% Note, or transfer the 6.70% Note by
book-entry, with the form entitled “Option of Holder to Elect Redemption on February 15, 2007” on the reverse side of such 6.70% Note, duly completed, to the Trustee during the period from December 15, 2006 and prior to 5:00 p.m.
(New York City time) on January 15, 2007 (or if such date is not a Business Day, then the next succeeding Business Day) at the address specified in such notice; 

 

	 	(g)	that any election on the part of a Holder to exercise the Redemption Right effected in accordance herewith shall be irrevocable on the part of the Holder and may not be
withdrawn; and 

  

	 	(h)	that Holders whose 6.70% Notes are being redeemed only in part will be issued a new 6.70% Note or 6.70% Notes equal in principal amount to the unredeemed portion of the
6.70% Notes surrendered (which unredeemed portion must be equal to $1,000 in principal amount or an integral multiple thereof). 

 On or prior to the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003 of the Indenture) an amount of cash sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) any accrued and unpaid interest on, all 6.70% Notes or portions thereof which are
to be redeemed on that date. 
 The 6.70% Notes to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price thereof and from and after such date (unless the Company shall default in the payment of the Redemption Price) such 6.70% Notes shall cease to bear interest. Upon submission of any 6.70% Note for redemption in accordance with the
provisions hereof, such 6.70% Note shall be paid by the Company at the Redemption Price, plus accrued and unpaid interest, if any, to the Redemption Date; provided , however , that installments of interest whose Stated Maturity is on
or prior to the Redemption Date shall be payable to the Holders of such 6.70% Notes registered as such on the relevant Record Date according to the terms and provisions hereof and Section 307 of the Indenture. 

If any 6.70% Note is to be redeemed in part, the Company shall execute and the Trustee, upon Company Order, shall authenticate and
deliver to the Holder of such 6.70% Note, without service charge, a new 6.70% Note or 6.70% Notes equal in principal amount to the unredeemed portion of the 6.70% Note surrendered (which unredeemed portion must be equal to $1,000 in principal amount
or an integral multiple thereof). 
 The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange
Act of 1934, as amended, and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable to the redemption of the 6.70% Notes pursuant to the Redemption Right. To the extent that the provisions of any
such rule conflict with the provisions hereof relating to the Redemption Right, the Company shall comply with the provisions of such rule and be deemed not to have breached its obligations relating to the Redemption Right by virtue thereof.

 All questions regarding the validity, form, eligibility (including time of receipt) and acceptance of any 6.70% Notes for
redemption will be determined by the Company, and its determination will be final and binding. 
 The 6.70% Notes are not
entitled to any sinking fund. 
 If an Event of Default with respect to the 6.70% Notes shall occur and be continuing, the
principal of the 6.70% Notes 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 aggregate 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 6.70% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 6.70% Note 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 6.70% Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this 6.70% Note 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 the 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 6.70% Note for the enforcement of any payment of principal hereof or interest hereon on or after the
respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this 6.70% Note or of the
Indenture shall alter or impair the obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this 6.70% Note at the times, place(s) and rates, and in the coin or currency, herein
prescribed. 
 [If a Global Security, insert - The holders of beneficial interests in this Global Security will

 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 transfer tax or other similar governmental charge payable in connection therewith. 
 Prior to due
presentment of this 6.70% Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this 6.70% Note is registered as the owner hereof for all purposes, whether or not

any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor Person,

 
either directly or through the Company or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it
being expressly understood that all such liability is hereby expressly waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 

THIS 6.70% NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

 [REVERSE OF 7 1/2% SENIOR NOTE DUE 2006] 

EL PASO CORPORATION 
 7 
1/2% Senior Note due 2006 
 This note 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 (the “ Original Indenture ”), as previously supplemented and as further supplemented by a Tenth Supplemental indenture, dated as of December 28, 2005 (the “ Supplemental Indenture ,” and the Original
Indenture, as so supplemented, the “ Indenture ”), between the Company and HSBC Bank USA, National Association, a national banking association, as successor-in-interest to JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as
trustee (the “ Trustee ,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This note is one of the notes in a series designated as 7 1/2% Senior Notes due 2006 of the Company (hereinafter called the
“ 7 1/2% Notes ”), issued under the Original Indenture, which 7 1/2% Notes are limited in aggregate principal amount to $204,910,000. 
 Except as provided in Sections 1006 and 1007 of the Original Indenture, neither the Indenture nor the
7 1/2% Notes limit or otherwise restrict the amount
of indebtedness which may be incurred or other securities which may be issued by the Company. The 7 1/2% Notes issued under the Indenture are direct, unsecured obligations of the Company and will mature on August 15, 2006. The 7 1/2% Notes rank on parity with all other unsecured, unsubordinated
indebtedness of the Company. 
 The 7 1/2% Notes will bear interest as set forth on the face hereof.

 The
7 1/2% Notes are not redeemable prior to their
Stated Maturity. 
 The 7 1/2% Notes are not entitled to any sinking fund. 

If an Event of Default with respect to the 7 1/2% Notes shall occur and be continuing, the principal of the 7 1/2% Notes 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 aggregate 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 7 1/2% Note shall be conclusive and binding upon such Holder and upon all future Holders of this 7 1/2% Note 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 7 1/2% Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this 7 1/2% Note 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 the 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 7 1/2% Note for the enforcement of any payment of principal hereof or
interest hereon on or after the respective due dates expressed herein. 

 No reference herein to the Indenture and no provision of this 7 1/2% Note or of the Indenture shall alter or impair the
obligation of the Company, which are absolute and unconditional, to pay the principal of, and premium, if any, and interest on this
7 1/2% Note at the times, place(s) and rates, and in
the coin or currency, herein prescribed. 
 [If a Global Security, insert - 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 hereof for any purpose under the Indenture.]

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this 7 1/2% Note is registrable in the Security Register, upon
