I, the undersigned officer of CenterPoint Energy Houston Electric, LLC, a Texas limited liability company (the “Company”), do hereby certify that I am an Authorized Officer of the Company as such term is defined in the Indenture (as defined herein). I am delivering this certificate pursuant to the authority granted in the Resolutions adopted by written consent of the sole Manager of the Company dated November 25, 2008, and Sections 105, 201, 301, 401(1), 401(5), 403(2)(A), 403(2)(B) and 1403 of the General Mortgage Indenture, dated as of October 10, 2002, as heretofore supplemented to the date hereof (as heretofore supplemented, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, National Association (as successor in trust to JPMorgan Chase Bank), as Trustee (the “Trustee”). Terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture, unless the context clearly requires otherwise. Based upon the foregoing, I hereby certify on behalf of the Company as follows:

(2) There shall be no limit upon the aggregate principal amount of the Series T Bonds that may be authenticated and delivered under the Indenture. The Trustee shall authenticate and deliver the Series T Bonds for original issue on November 25, 2008 (the “Issue Date”) in the aggregate principal amount of $600,000,000, upon a Company Order for the authentication and delivery thereof and satisfaction of Section 401 of the Indenture.

(3) Not applicable.

The amount of principal of the Series T Bonds payable by the Company on any such date shall equal the aggregate principal amount of the Loans due and payable on such date pursuant to the

Credit Agreement (but, in no event, shall exceed the aggregate principal amount of the Series T Bonds). The obligation of the Company to make any payment of the principal on the Series T Bonds shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has paid the principal then due and payable on the Loans made pursuant to the Credit Agreement.

(5) The Series T Bonds shall bear interest from the time hereinafter provided at such rate per annum as shall cause the amount of interest payable on each Interest Payment Date (as hereinafter defined) on the Series T Bonds to equal the amount of interest payable on such Interest Payment Date under the Credit Agreement. Such interest on the Series T Bonds shall be payable on the same dates as interest is payable from time to time pursuant to the Credit Agreement (each such date herein called an “Interest Payment Date”), until the maturity of the Series T Bonds, or, in the case of any default by the Company in the payment of the principal due on the Series T Bonds, until the Company’s obligation with respect to the payment of such principal shall be discharged as provided in the Indenture. The amount of interest payable from time to time under the Credit Agreement, the basis on which such interest is computed and the dates on which such interest is payable are set forth in the Credit Agreement. Each Series T Bond shall bear interest (a) from the date of initial authentication of this Bond to but excluding the Interest Payment Date next succeeding, and (b) from each Interest Payment Date to but excluding the Interest Payment Date next succeeding. The obligation of the Company to make any payment of interest on the Series T Bonds shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has paid the interest on the Loans then due and payable pursuant to the Credit Agreement.

The obligation of the Company to make any payment of the principal on this Bond shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has paid the principal then due and payable on the Loans made pursuant to the Credit Agreement.

Interest shall be payable on this Bond on each Interest Payment Date (as hereinafter defined) at such rate per annum as shall cause the amount of interest payable on such Interest Payment Date on this Bond to equal the amount of interest payable on such Interest Payment Date under the Credit Agreement. Such interest shall be payable on the same dates as interest is payable from time to time in respect of the Loans pursuant to the Credit Agreement (each such date herein called an “Interest Payment Date”), until the maturity of this Bond, or, if the Company shall default in the payment of the principal due on this Bond, until the Company’s obligation with respect to the payment of such principal shall be discharged as provided in the Indenture. The amount of interest payable from time to time under the Credit Agreement, the basis on which such interest is computed and the dates on which such interest is payable

are set forth in the Credit Agreement. This Bond shall bear interest (a) from the date of initial authentication of this Bond to but excluding the Interest Payment Date next succeeding, and (b) from each Interest Payment Date to but excluding the Interest Payment Date next succeeding. The obligation of the Company to make any payment of interest on this Bond shall be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that the Company has paid the interest on the Loans then due and payable pursuant to the Credit Agreement.

This Bond is issued to the Administrative Agent by the Company pursuant to the Company’s obligations under the Credit Agreement, dated as of November 25, 2008 (as amended, supplemented, restated or otherwise modified from time to time, the “Credit Agreement”), among the Company, Bank of America, N.A. and Deutsche Bank Securities Inc., as Co-Syndication Agents, HSBC Bank USA, N.A. and The Bank of Nova Scotia, as Co-Documentation Agents, Citicorp North America, Inc., as Administrative Agent, and the banks and other financial institutions from time to time parties thereto (the “Banks”). This Bond shall be held by the Administrative Agent subject to the terms of the Pledge Agreement, dated as of November 25, 2008, between the Company, the Administrative Agent and the Administrative Agent in such capacity under the Credit Agreement. Any capitalized terms used herein and not defined herein shall have the meanings specified in the Indenture (as defined below), unless otherwise noted.

The Administrative Agent shall surrender this Bond to the Trustee when all of the principal of and interest on the Loans made pursuant to the Credit Agreement shall have been duly paid and the Credit Agreement shall have been terminated.

Payments of the principal of and interest on this Bond shall be made at the Corporate Trust Office of The Bank of New York Mellon Trust Company, National Association, as Trustee, located at 601 Travis Street, 16th Floor, Houston, Texas 77002, or at such other office or agency as may be designated for such purpose by the Company from time to time. Payment of the principal of and interest on this Bond, as aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts.

This Bond is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or more series under and equally secured by a General Mortgage Indenture, dated as of October 10, 2002 (such Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, National Association (as successor in trust to 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 description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities are, and are to be, authenticated and delivered and secured. The acceptance of this Bond shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Bond is one of the series designated above.

The Bonds of this series will not be entitled to the benefit of any sinking fund or voluntary redemption provisions.

If an Event of Default, as defined in the Indenture, shall occur and be continuing, the principal of this Bond 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 Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; PROVIDED, HOWEVER, that if there shall be Securities of more than one series Outstanding under the Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and PROVIDED, FURTHER, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed

supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and PROVIDED, FURTHER, that the Indenture permits the Trustee to enter into one or more supplemental indentures for limited purposes without the consent of any Holders of Securities. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, 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 Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Bond.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Bond is registrable in the Security Register, upon surrender of this Bond for registration of transfer at the Corporate Trust Office of The Bank of New York Mellon Trust Company, National Association in Houston, Texas or such other office or agency as may be designated by the Company from time to time, 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 Bonds of this series of authorized denominations and of like tenor and aggregate principal amount, will be issued to the designated transferee or transferees.

This Bond has been issued by the Company to the Administrative Agent for the benefit of the holders of the Loans to (i) provide security for the payment of the Company’s obligations on the Loans under the Credit Agreement and (ii) provide to the holders of such Loans the benefits of the security provided for this Bond pursuant to the Indenture.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in whose name this Bond shall be registered upon the Security Register for the Bonds of this series as the absolute owner of such Bond for the purpose of receiving payment of or on account of the principal of and interest on this Bond and for all other purposes, whether or not this Bond be overdue, and neither the Company nor the Trustee shall be affected by any notice to the contrary; and all such payments so made to such registered owner or upon his order shall be valid and effectual to satisfy and discharge the liability upon this Bond to the extent of the sum or sums paid.

The Trustee may conclusively presume that the obligation of the Company to pay the principal of and interest on this Bond shall have been fully satisfied and discharged unless and until it shall have received a written notice from the Administrative Agent, signed by an authorized officer of the Administrative Agent and attested by the Secretary or an Assistant Secretary of the Administrative Agent within 90 days after the applicable Interest Payment Date, stating that the payment of principal of or interest on this Bond has not been fully paid when due and specifying the amount of funds required to make such payment.

Before any transfer of this Bond by the registered holder or his or its legal representative will be recognized or given effect by the Company or the Trustee, the registered holder shall note the amounts of all reductions in the principal of the Loans under the Credit Agreement, and shall notify the Company and the Trustee of the name and address of the transferee and shall afford the Company and the Trustee the opportunity of verifying the notation as to such reductions. By acceptance hereof the holder of this Bond and each transferee shall be deemed to have agreed to indemnify and hold harmless the Company and the Trustee against all losses, claims, damages or liability arising out of any failure on part of the holder or of any such transferee to comply with the requirements of the preceding sentence.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in any indenture supplemental thereto, or in any Bond or coupon thereby secured, or because of any indebtedness thereby secured, shall be had against any incorporator, member, manager, stockholder, officer, director or employee, as such, past, present or future, of the Company or any predecessor or successor corporation or company, either directly or through the Company or any predecessor or successor corporation or company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture, any indenture supplemental thereto and the obligations thereby

secured, are solely corporate obligations of the Company, and that no personal liability whatsoever shall attach to, or be incurred by, such incorporators, members, managers, stockholders, officers, directors or employees, as such, of the Company or of any predecessor or successor corporation or company, or any of them, because of the creation of the indebtedness thereby authorized, or under or by reason of any of the obligations, covenants or agreements contained in the Indenture or in any indenture supplemental thereto or in any of the Bonds or coupons thereby secured, or implied therefrom.

This Bond shall be governed by and construed in accordance with the law of the State of New York except as provided in the Indenture.

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

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.
