The Trustee shall authenticate and deliver the Notes for original issue on the Issue Date in the aggregate principal amount of $500,000,000 upon a Company Order for the authentication and delivery thereof and satisfaction of Sections 301 and 303 of the Original Indenture.  Such order shall specify the amount of the     Notes to be authenticated, the date on which the original issue of Notes is to be authenticated and the name or names of the initial Holder or Holders.

Section 203    Stated Maturity.  The stated maturity of the Notes shall be September 1,         2022 (the “Maturity Date”).
 
Section 204    Interest and Interest Rates.
 
(a)    The Notes shall bear interest at a rate of 2.50% per year, from and including                             August 10, 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 August 15 (each a “Regular Record Date”) (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date.
 
(b)    Any such interest not so punctually paid or duly provided for shall forthwith cease                       to be payable to the Holder on such Regular Record Date 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 quotation system on which the Notes may be listed or traded, and upon such notice as may be required by such            exchange or automated quotation system, all as more fully provided in the Indenture.

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 the rate of 2.50% per annum (to the extent permitted by law), from the dates such amounts are due until they are paid or made available for payment, and such               interest shall be payable on demand.

At the option of the Company,          payment of interest may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer in immediately         available funds at such place and to such account as may be designated in writing by the Person entitled thereto as specified in the Security Register.
 
Section 206    Place of Registration or Exchange; Notices and Demands With Respect to    the Notes.  The place where the Holders of the Notes may present the Notes for registration of              transfer or exchange and may make notices and demands to or upon the Company in respect of      the Notes shall be the Corporate Trust Office of the Trustee.

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 August 1,        2022 (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 12.5 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.

“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 

6

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 four 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 four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of Barclays Capital Inc., Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC or MUFG Securities Americas Inc. 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) Barclays Capital Inc., Goldman Sachs & Co. LLC and Morgan Stanley and Co. LLC and a primary U.S. government securities dealer in       the United States of America (a “Primary Treasury Dealer”) designated by MUFG Securities Americas Inc. and their respective affiliates or successors, each of which is 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.
 

7

Section 303   Partial Redemption.  If fewer than all of the Notes are to be redeemed by         the Company pursuant to this Article III, 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 304   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.

CENTERPOINT ENERGY, INC.

2.50% NOTES DUE 2022

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 May 19, 2003 (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 JPMorgan Chase Bank)), 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 $500,000,000; 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 August 1, 2022 (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 12.5 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 shall select two yields – one for the maturity immediately before and one for the maturity   

A-6

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 four 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 four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of Barclays Capital Inc., Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC or MUFG Securities Americas Inc. 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) Barclays Capital Inc., Goldman Sachs & Co. LLC and Morgan Stanley and Co. LLC and a primary U.S. government securities dealer in      the United States of America (a “Primary Treasury Dealer”) designated by MUFG Securities Americas Inc. and their respective affiliates or successors, each of which is 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 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.

[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-7

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-8

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.
