The Series of Securities

SECTION 2.1 The Form and Title of the Securities.

There is hereby established, in accordance with Section 3.1 of the Original Indenture, a new series of Securities to be issued under the Indenture and to be designated as the Company’s 4.70% Senior Notes due 2042 (the “Notes”). The Notes shall be substantially in the form attached as Exhibit A hereto, with such appropriate insertions, omissions, substitutions, notations and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as the Company may deem appropriate or as may be required or appropriate to comply with any laws or with any rules made pursuant thereto or with the rules of any securities exchange or automated quotation system on which the Notes may be listed or traded, or to conform to general usage, or as may, consistently with the Indenture, be determined by the Officer executing such Notes, as evidenced by his execution thereof.

The Notes shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to, the terms, conditions and covenants of the Original Indenture as supplemented by this Supplemental Indenture (including the form of Note attached as Exhibit A hereto (the terms of which are incorporated in and made a part of this Supplemental Indenture for all intents and purposes)).

SECTION 2.2 Amount.

The aggregate principal amount of the Notes that may be authenticated and delivered pursuant hereto is unlimited. The Trustee shall initially authenticate and deliver the Notes for original issue on the date hereof in an initial aggregate principal amount of $475,000,000, upon delivery to the Trustee of a Company Order for the authentication and delivery of the Notes. The aggregate principal amount of the Notes to be issued hereunder may be increased at any time hereafter and the series may be reopened for issuances of Additional Notes, upon Company Order, without the consent of any Holder and without any further supplement or amendment to the Original Indenture or this Supplemental Indenture, and accordingly, Additional Notes may be issued on any Business Day after the date hereof. The Notes issued on the date hereof and any such Additional Notes that may be issued hereafter shall be part of the same series of Securities for all purposes under the Indenture.

SECTION 2.3 Denominations.

The Notes shall be issuable in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

SECTION 2.4 Stated Maturity.

The Stated Maturity of the principal of the Notes shall be November 1, 2042.

SECTION 2.5 Interest and Interest Rates.

The rate or rates at which the Notes shall bear interest, the date or dates from which such interest shall accrue, the Interest Payment Dates on which any such interest shall be payable and the Regular Record Date for any interest payable on any Interest Payment Date, in each case, shall be as set forth in the form of Note attached as Exhibit A hereto.

SECTION 2.6 Place of Payment.

As long as any Notes are Outstanding, the Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where the principal of and any premium and interest on the Notes shall be payable, where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. Unless otherwise designated by the Company by written notice to the Trustee, such office or agency shall be the Trustee’s Corporate Trust Office, as long as such office is located in the Borough of Manhattan, The City of New York. The Company will give prompt written notice to the Trustee of any change in the location of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more additional offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 2.7 Optional Redemption of the Notes.

At its option, the Company may redeem the Notes, in whole or in part, in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof, at any time or from time to time, at the applicable Redemption Price determined as set forth in the form of Note attached hereto as Exhibit A, in accordance with the terms set forth in the Notes and in accordance with Article Eleven of the Original Indenture.

SECTION 2.8 Defeasance and Discharge; Covenant Defeasance.

Article Thirteen of the Original Indenture (as amended and supplemented by this Supplemental Indenture) shall apply to the Notes. Furthermore, each of the covenants set forth in Article Four of this Supplemental Indenture, and the Event of Default specified in Section 5.1(c) of the Original Indenture, shall, in each case, constitute “Additional Defeasible Provisions” (as such term is used in the Original Indenture).

SECTION 2.9 Global Securities.

The Notes shall initially be issuable in whole or in part in the form of one or more Global Securities. Such Global Securities (i) shall be deposited with, or on behalf of, The Depository Trust Company, New York, New York, which shall act as Depositary with respect to the Notes, (ii) shall bear the legends applicable to Global Securities set forth in Sections 2.2 and 2.4 of the Original Indenture, (iii) may be exchanged in whole or in part for Securities in definitive form upon the terms and subject to the conditions provided in Section 3.5 of the Original Indenture and in this Supplemental Indenture and (iv) shall otherwise be subject to the applicable provisions of the Indenture.

SECTION 2.10 Parent Guarantee.

Article Fourteen of the Original Indenture (as amended and supplemented by this Supplemental Indenture) shall apply to the Notes. The MLP hereby agrees that it shall be a Guarantor of the Notes in accordance with Article Fourteen of the Original Indenture. For the purposes of this Supplemental Indenture and the Notes (including without limitation the provisions of the Original Indenture to the extent applicable thereto), the term “Guarantor” shall mean the MLP, and accordingly, the Parent Guarantee of the MLP shall be a Securities Guarantee with respect to the Indenture and the Notes; provided, however that such Securities Guarantee shall not apply to any obligations under any series of Securities other than the Notes.

To evidence its Parent Guarantee set forth in Article Fourteen of the Original Indenture (as amended and supplemented by this Supplemental Indenture), the Guarantor hereby agrees that a notation of such Parent Guarantee substantially in the form attached as Exhibit B hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Supplemental Indenture will be executed on behalf of such Guarantor by one of its Officers.

The Guarantor hereby agrees that its Parent Guarantee set forth in Article Fourteen of the Original Indenture (as amended and supplemented by this Supplemental Indenture) will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Parent Guarantee.

If an Officer whose signature is on this Supplemental Indenture or on the notation of such Parent Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a notation of such Parent Guarantee is endorsed, the Parent Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Parent Guarantee set forth in the Indenture on behalf of the Guarantor.

SECTION 4.3 Offer to Purchase Upon a Change of Control Triggering Event.

Section 10.8 Offer to Purchase Upon a Change of Control Triggering Event.

(a) If a Change of Control Triggering Event occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer (“Change of Control Offer”) on the terms set forth below. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of the Notes repurchased pursuant to the foregoing, plus accrued and unpaid interest on such Notes repurchased to the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of such Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company will mail a notice to each Holder of Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of this Indenture by virtue of the Company’s compliance with such securities laws or regulations.

(b) With respect to any Change of Control Offer, on the Change of Control Payment Date, the Company will, to the extent lawful:

(i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent (to the extent the Paying Agent acts as tender agent for such offer) an amount equal to the Change of Control Payment in respect of all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; and

(iii) deliver or cause to be delivered to the Trustee all Notes accepted for purchase together with an Officer’s Certificate stating the aggregate principal amount of the Notes or portions thereof being purchased by the Company.

(c) Upon receipt of the Change of Control Payment from the Company, the Paying Agent (to the extent the Paying Agent acts as tender agent for such offer) will promptly mail to each Holder of Notes properly tendered pursuant to the Change of Control Offer the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee, upon receipt of a Company Order, will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment.

(d) The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(e) Notwithstanding anything to the contrary in this Section 10.8, the Company will not be required to make a Change of Control Offer with respect to the Notes upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture that are applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, or (ii) prior to the Change of Control Triggering Event, notice of redemption of all outstanding Notes has been given pursuant to the redemption provisions of this Indenture, unless and until there is a default in payment of the applicable Redemption Price.

(f) A Change of Control Offer may be made with respect to the Notes in advance of a Change of Control Triggering Event, and conditioned upon the occurrence of such Change of Control Triggering Event, if a definitive agreement for the Change of Control Triggering Event is in place at the time of making the Change of Control Offer. Notes repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not Outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to clause (e) of this Section 10.8 will have the status of Notes issued and Outstanding.

(g) In the event that, pursuant to this Section 10.8, the Company shall be required to commence a Change of Control Offer, it shall follow the procedures specified above in this Section 10.8, and, to the extent not inconsistent therewith, the procedures specified below in this paragraph (g).

(i) A Change of Control Offer shall remain open for a period of no less than 30 days and no more than 60 days following its commencement, except to the extent that a longer period is required by applicable law (the “Offer Period”). Promptly after the

termination of the Offer Period, the Company shall purchase all Notes tendered and not withdrawn in response to the Change of Control Offer in accordance with Section 10.8(b) above.

(ii) Upon the commencement of a Change of Control Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders of Notes. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Change of Control Offer. The Change of Control Offer shall be made to all Holders of Notes. The notice, which shall govern the terms of the Change of Control Offer, shall state:

(A) that the Change of Control Offer is being made pursuant to this Section 10.8, and the length of time the Change of Control Offer shall remain open;

(B) the purchase price and the Change of Control Payment Date;

(D) that, unless the Company defaults in making such payment, any Note (or portion thereof) accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date;

(E) that Holders electing to have a Note purchased pursuant to a Change of Control Offer may elect to have such Notes purchased equal to $2,000 and integral multiples of $1,000 in excess thereof;

(F) that Holders electing to have a Note purchased pursuant to any Change of Control Offer shall be required to surrender such Note, with the form entitled “Option of Holder to Elect Repurchase” on the reverse of the Note completed, or transfer by book entry transfer, to the Company, the Depositary, if appointed by the Company, or a Paying Agent (to the extent the Paying Agent acts as tender agent for such offer) at the address specified in the notice at least three Business Days before the Purchase Date;

(G) that Holders shall be entitled to withdraw their election if the Company, the Depositary or the Paying Agent (to the extent the Paying Agent acts as tender agent for such offer), as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of such Note the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Note purchased; and

(H) that Holders whose Notes were purchased only in part, pursuant to this section, shall be issued new Notes equal in principal amount to the unpurchased portion of such Notes surrendered (or transferred by book entry transfer).

[REVERSE OF NOTE]

EL PASO PIPELINE PARTNERS OPERATING COMPANY, L.L.C.

4.70% Senior Note due 2042

This Security is one of a duly authorized issue of senior securities of the Company (the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 30, 2010, as amended and supplemented by the Fourth Supplemental Indenture thereto dated as of November 8, 2012 (such Indenture, as so amended and supplemented being referred to herein as the “Indenture”), by and among the Company, El Paso Pipeline Partners, L.P. (the “Guarantor”) and HSBC Bank USA, National Association, a national banking association organized and existing under the laws of the United States of America, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used but not defined herein have the meanings set forth in the Indenture. This Security is one of the series designated on the face hereof.

This Security is the general, unsecured, senior obligation of the Company and is guaranteed pursuant to a guarantee (the “Parent Guarantee”) by the Guarantor. The Parent Guarantee is the general, unsecured, senior obligation of the Guarantor.

This Security is redeemable, in whole or in part, at the Company’s option at any time prior to maturity. Beginning on May 1, 2042, the Redemption Price will equal 100% of the principal amount of this Security plus accrued and unpaid interest to the Redemption Date. Prior to May 1, 2042, the Redemption Price will equal the greater of (a) 100% of the principal amount of this Security, and (b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest (not including any portion of those payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 35 basis points, plus, in each case, accrued and unpaid interest to the Redemption Date.

For purposes of determining the Redemption Price prior to May 1, 2042, the following definitions shall apply:

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for the Redemption Date. The Adjusted Treasury Rate will be calculated on the third Business Day preceding the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the applicable Quotation Agent as having a maturity comparable to the remaining term of this Security 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 Security.

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

“Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

“Reference Treasury Dealer” means (a) Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, RBC Capital Markets, LLC and RBS Securities Inc.; provided that, if any of the foregoing is not then a primary U.S. Government securities dealer (a “Primary Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer; and (b) any other Primary Treasury Dealers selected by the Company.

“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 applicable

Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding that Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on this Security or the portions hereof called for redemption.

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

The Company is not required to make mandatory redemption or sinking fund payments with respect to this Security.

If a Change of Control Triggering Event occurs, each Holder of Securities will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Securities pursuant to an offer (“Change of Control Offer”) on the terms set forth in the Indenture. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid interest on the Securities repurchased to the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of Securities on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company will mail a notice to each Holder of Securities describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Securities on the Change of Control Payment Date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture and described in such notice.

The Indenture contains provisions for defeasance at any time of (1) the entire indebtedness of this Security or (2) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantor 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 Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected (with each series voting as a separate class). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company and the Guarantor with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, regardless of whether notation of such consent or waiver is made upon this Security.

No Holder of this Security shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of this series, (b) the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under the Indenture, (c) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding and (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of this series; it

being understood and intended that no one or more of such Holders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Indenture, except in the manner therein provided and for the equal and ratable benefit of all such Holders.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place(s) and rate, and in the coin or currency, herein prescribed.

[If a Global Security, insert—This Global Security or portion hereof may not be exchanged for Definitive Securities of this series except in the limited circumstances provided in the Indenture. The holders of beneficial interests in this Global Security will not be entitled to receive physical delivery of Definitive Securities except as described in the Indenture and will not be considered the Holders thereof for any purpose under the Indenture.]

[If a Definitive Security, insert—As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in The City of New York, or, subject to any laws or regulations applicable thereto and to the right of the Company (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the offices of the Security Registrar 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 such Holder’s attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.]

The Securities of this series are issuable only in registered form without coupons in denominations of U.S. $2,000 and any integral multiple of U.S. $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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.

Prior to due presentment of this Security for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and none of the Company, the Guarantor, 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 the Parent Guarantee endorsed thereon, or for any claim based thereon or otherwise in respect thereof, or in any Security or in the Parent Guarantee, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, shareholder, partner, member, officer, manager or director, as such, past, present or future, of the Company or the Guarantor or of any successor Person, either directly or through the Company or the Guarantor 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 execution of the Indenture and the issuance of the Securities.

This Security shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
