August 23, 2017 (the “Issue Date”) to, but excluding, the Maturity Date. Such interest shall be payable semiannually in arrears on March 1 and September 1 of each year
(each an “Interest Payment Date”), beginning March 1, 2018 to the persons in whose names the Notes (or one or more Predecessor Securities) are registered at the close of business on February 15 and

and shall either (i) be paid to the Person in whose name such Note (or one or more Predecessor Securities) is registered at the close of business on the Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee,
notice whereof shall be given to Holders of the Notes not less than 10 days prior to such Special Record Date, or (ii) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange or automated

interest payable for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the days elapsed in any partial month. In the event that any date on which interest is payable on a Note is not a Business Day, then
a payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date the payment
was originally payable. 
 (d) Any principal and premium, if any, and any installment of interest, which is overdue shall bear interest at

thereto as specified in the Security Register.

 Section 401 Redemption Price. The Notes shall be redeemable, at the option of the Company, at any time or from
time to time, in whole or in part, on any date prior to March 1, 2047 (the “Par Call Date”) at a price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) the sum of the
present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due if the Notes matured on the Par Call Date but for the redemption (not including any portion of such payments of interest
accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 20 basis points plus, in each case, accrued and unpaid interest
on the principal amount being redeemed, if any, to, but excluding, the Redemption Date. On or after the Par Call Date, the Company may redeem the Notes, at any time or from time to time, in whole or in part, by paying 100% of the principal amount of
the Notes to be redeemed plus accrued and unpaid interest on the principal amount being redeemed, if any, to, but excluding, the Redemption Date. The Trustee shall have no responsibility for the calculation of such amount.

 Section 402 Calculation. The Treasury Rate will be calculated by the Independent
Investment Banker on the third Business Day preceding the Redemption Date. For purposes of this Article Four, the following terms shall mean as follows: 

“Treasury Rate” means, with respect to any Redemption Date, the yield calculated on the third Business Day preceding the
redemption date, as follows: for the latest day that appears in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any
successor publication) under the caption “Treasury Constant Maturities—Nominal”, the Independent Investment Banker shall select two yields – one for the maturity immediately before and one for the maturity immediately after the
remaining maturity of the Notes (assuming the Notes matured on the Par Call Date) – and shall interpolate on a straight-line basis using such yields; if there is no such maturity either before or after, the Independent Investment Banker shall
select the maturity closest to the Par Call Date that appears on the release; or 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 semiannual equivalent yield to maturity of the applicable Comparable Treasury Issue, calculated by the Independent Investment Banker 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. 
 “Comparable Treasury Issue” means the U.S. Treasury security
selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term (“Remaining Term”) of the Notes to be redeemed (assuming for this purpose that the Notes matured on the Par
Call Date) 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 Notes. 

“Comparable Treasury Price” means (1) the average of three Reference Treasury Dealer Quotations for such Redemption
Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Independent Investment Banker” means one of Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC or Morgan
Stanley & Co. LLC, as specified by the Company, or if these firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing selected by the Company. 

“Reference Treasury Dealer” means each of (1) Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC and Morgan
Stanley & Co. LLC, each of which is a primary U.S. government securities dealer in the United States of America (a “Primary Treasury Dealer”), provided, however, that if any of the foregoing shall cease to be a Primary Treasury
Dealer, the Company shall substitute therefor another Primary Treasury Dealer and (2) any other Primary Treasury Dealer selected by the Company after consultation with the Independent Investment Banker. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Independent Investment Banker, 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 Independent Investment Banker at
5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

  
 9 

 Section 403 Partial Redemption. If fewer than all of the Notes are to be
redeemed by the Company pursuant to this Article Four, not more than 60 days prior to the Redemption Date, the particular Notes or portions thereof for redemption will be selected from the outstanding Notes not previously called by such method as
the Trustee deems fair and appropriate. The Trustee may select for redemption Notes and portions of Notes in amounts of $1,000 or whole multiples of $1,000. A new Note in principal amount equal to the unredeemed portion of the original Note
shall be issued upon the cancellation of the original Note. In the case of a partial redemption of Notes registered in the name of Cede & Co, the Notes to be redeemed will be determined in accordance with the procedures of The Depository
Trust Company. 
 Section 404 Notice of Optional Redemption. The Trustee, at the written direction of the Company, will
send a notice of redemption prepared by the Company to each holder of Notes to be redeemed by first-class mail (or in accordance with the procedures of The Depository Trust Company with respect to Notes registered in the name of Cede & Co.)
at least 15 and not more than 60 days prior to the date fixed for redemption. Unless the Company defaults on payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the Redemption
Date. If any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount to be redeemed.

 [FORM OF REVERSE SIDE OF SECURITY] 

CENTERPOINT ENERGY RESOURCES CORP. 

4.10% NOTES DUE 2047 
 This
Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of February 1, 1998 (herein called the “
Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, National Association (successor to JPMorgan Chase Bank, National Association (formerly Chase
Bank of Texas, National Association)), as Trustee (herein called 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, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $300,000,000; provided, however, that the authorized aggregate principal amount of the Securities may
be increased above such amount by a Board Resolution to such effect. 
 This Security shall be redeemable, at the option of the Company, at
any time or from time to time, in whole or in part, on any date prior to March 1, 2047 (the “Par Call Date”) at a price equal to the greater of (i) 100% of the principal amount of this Security (or the portion hereof to be
redeemed) or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed that would be due if this Security (or the portion hereof to be redeemed) matured on the Par Call
Date but for the redemption (not including any portion of such payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the
applicable Treasury Rate plus 20 basis points plus, in each case, accrued and unpaid interest on the principal amount being redeemed, if any, to, but excluding, the Redemption Date. On or after the Par Call Date, the Company may redeem this
Security, at any time or from time to time, in whole or in part, by paying 100% of the principal amount of this Security (or such portion to be redeemed) plus accrued and unpaid interest on the principal amount being redeemed, if any, to, but
excluding, the Redemption Date. The Trustee shall have no responsibility for the calculation of such amount. 
 The Treasury Rate will be
calculated by the Independent Investment Banker on the third Business Day preceding the Redemption Date. For purposes of calculating the Redemption Price, the following terms shall mean as follows: 

“Treasury Rate” means, with respect to any Redemption Date, the yield calculated on the third Business Day preceding the redemption
date, as follows: for the latest day that appears in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor
publication) under the caption “Treasury Constant Maturities - Nominal”, the Independent Investment Banker 

  
 A-6 

 
shall select two yields – one for the maturity immediately before and one for the maturity immediately after the remaining maturity of this Security (assuming this Security matured on the
Par Call Date) – and shall interpolate on a straight-line basis using such yields; if there is no such maturity either before or after, the Independent Investment Banker shall select the maturity closest to the Par Call Date that appears on the
release; or 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 semiannual equivalent yield to maturity of the Comparable
Treasury Issue, calculated by the Independent Investment Banker 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. 

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having an actual or
interpolated maturity comparable to the remaining term (“Remaining Term”) of this Security to be redeemed (assuming for this purpose that the Securities matured on the Par Call Date) 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 (1) the average of three Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Independent Investment Banker” means one of Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC or Morgan
Stanley & Co. LLC as specified by the Company, or if these firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing selected by the Company. 

“Reference Treasury Dealer” means each of (1) Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC and Morgan
Stanley & Co. LLC, each of which is a primary U.S. government securities dealer in the United States of America (a “Primary Treasury Dealer”), provided, however, that if any of the foregoing shall cease to be a Primary Treasury
Dealer, the Company shall substitute therefor another Primary Treasury Dealer and (2) any other Primary Treasury Dealer selected by the Company after consultation with the Independent Investment Banker. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average,
as determined by the Independent Investment Banker, 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 Independent Investment Banker at 5:00 p.m.,
New York City time, on the third Business Day preceding such Redemption Date. 
 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 Securities of this series are not entitled to the benefit of any sinking fund. 

  
 A-7 

 The Indenture contains provisions for satisfaction and discharge of the entire indebtedness of
this Security upon compliance by the Company with certain conditions set forth in the Indenture. 
 The Indenture contains provisions for
defeasance at any time of the entire indebtedness of this Security or 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 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 principal amount of the Securities at the time Outstanding of each series to be affected. 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 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, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than 33% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and
shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment
of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the
Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and
rate, and in the coin or currency, herein prescribed. 

  
 A-8 

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer
of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are

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. 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.

Indenture shall have the meanings assigned to them in the Indenture.

REVERSE OF NOTE

 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in one or more series under an Indenture (the “Base Indenture”), dated as of September 8, 2014, between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee), as amended and supplemented by the First Supplemental Indenture, dated as of September 8, 2014, between the Company and the Trustee (the “First Supplemental Indenture,” and the Base Indenture as supplemented by the First Supplemental Indenture, the “Indenture”), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.  This Note constitutes a duly authorized issuance of “Additional Securities” under the Indenture relating to the Company’s 5.25% Senior Notes due 2024.  The Company initially issued $500,000,000 aggregate principal amount of such securities under the Indenture on September 8, 2014 (the “Initial Securities”).  This Note shall have the same ranking and the same interest rate, maturity and other terms as the Initial Securities, except for the public offering price, the issue date and the initial interest payment date and initial interest accrual date. This Note, together with the Initial Securities, shall constitute a single series of securities under the Indenture.

 

All terms used but not defined in this Note that are defined in the Indenture shall have the meaning assigned to them in the Indenture.

 

Except as otherwise may be specified in the Indenture, at any time or from time to time prior to June 15, 2024, the Company shall have the right to redeem the Notes, in whole or in part, upon not less than 30 days nor more than 60 days’ notice at its option, at a redemption price equal to the greater of:

 

i.                  100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date; and

 

ii.               as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date), discounted to the Redemption Date on a semiannual basis (assuming a 360-day year comprised of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points, plus accrued and unpaid interest thereon to but excluding the Redemption Date (provided, in each case, that interest payments due on or prior to the Redemption Date will be paid to the record holders of such Notes on the relevant Record Date).

 

At any time or from time to time on or after June 15, 2024, the Company shall have the right to redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date (provided, in each case, that interest payments due on or prior to

 

R-1

 

the Redemption Date will be paid to the record holders of such Notes on the relevant Record Date).

 

The term “Optional Redemption Price” means, with respect to any redemption of Notes, the applicable redemption price for such Notes set forth in the preceding two paragraphs; and the term “Redemption Date” means, with respect to any redemption of Notes, the date fixed for such redemption pursuant to the Indenture and the Notes.

 

The Company shall mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) notice of any redemption to the registered holders of the Notes to be redeemed at least 30 and not more than 60 days prior to the Redemption Date. If Notes are only partially redeemed pursuant to the preceding paragraphs, the Notes to be redeemed will be selected by the Trustee in such manner as in its sole discretion it shall deem appropriate and fair; provided that if at the time of redemption the Notes to be redeemed are registered as a Global Note, the Depositary shall determine, in accordance with its procedures, the principal amount of the Notes to be redeemed held by each of its participants that holds a position in such Notes. The Optional Redemption Price for any Notes to be redeemed shall be paid prior to 12:00 noon, New York City time, on the Redemption Date or at such later time as is then permitted by the rules of the Depositary for the related Notes (if then registered as a Global Note); provided that the Company shall deposit with the Trustee an amount sufficient to pay the Optional Redemption Price for the Notes to be redeemed by 10:00 a.m., New York City time, on the date such Optional Redemption Price is to be paid.

 

In the event of redemption of this Note in part only, a new Note or Notes for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the cancellation hereof. Except as set forth in the preceding paragraphs and in Article 3 of the First Supplemental Indenture, the Company may not redeem the Notes at its option prior to the Maturity Date.

 

Upon a Change of Control Triggering Event, the Company may be required to offer to repurchase all or any part of the Notes.

 

The Notes are not entitled to the benefit of any sinking fund.

 

The Indenture contains provisions for defeasance of the obligations of the Company at any time upon compliance by the Company with certain conditions set forth therein, which provisions apply to the Notes.

 

If an Event of Default with respect to Notes shall occur and be continuing, the principal of the 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 Notes at any time by the Company and the Trustee, with the consent of the holders of a majority in the aggregate principal amount of the Securities of each series affected thereby at the time Outstanding, voting as a single class.  The Indenture also contains provisions permitting the holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the holders of all Notes, to waive certain past defaults under the Indenture and their

 

R-2

 

consequences.  Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note 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 Note.

 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are 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 his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
