CENTERPOINT ENERGY RESTORATION BOND COMPANY, LLC

SENIOR SECURED SYSTEM RESTORATION BONDS, Tranche [    ].

CenterPoint Energy Restoration Bond Company, LLC, a limited liability company organized and existing under the laws of the State of Delaware (herein referred to as the “Issuer”), for value received, hereby promises to pay to the registered holder under Section 2.05 of the Indenture, or registered assigns, the Initial Principal Amount shown above in semiannual installments on the Payment Dates (as defined below) and in the amounts specified on the reverse hereof or, if less, the amounts determined pursuant to Section 8.02(d) of the Indenture referred to on the reverse hereof, in each year, commencing on the date determined as provided on the reverse hereof and ending on or before the Final Maturity Date of this Tranche [    ] Bond, to pay the entire unpaid principal hereof on such Final Maturity Date and to pay Interest, at the Bond Rate shown above, on each February 15 and August 15, or if any such day is not a Business Day, the next succeeding Business Day, commencing on August 15, 2010 and continuing until the earlier of the payment of the Principal hereof and the Final Maturity Date of this Tranche [    ] Bond (each a “Payment Date”), on the Principal amount of this Tranche [    ] Bond outstanding from time to time. Interest on this Tranche [    ] Bond will accrue for each Payment Date from the most recent Payment Date on which Interest has been paid to but excluding such Payment Date or, if no

A-1

Interest has yet been paid, from November 25, 2009. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Such Principal of and Interest on this Tranche [    ] Bond shall be paid in the manner specified on the reverse hereof.

The Principal of and Interest on this Tranche [    ] Bond are payable in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to this Tranche [    ] Bond shall be applied first to Interest due and payable on this Tranche [    ] Bond as provided above and then to the unpaid Principal of and premium, if any, on this Tranche [    ] Bond, all in the manner set forth in Section 8.02(d) of the Indenture.

This Tranche [    ] Bond is a “transition bond” as such term is defined in the Public Utility Regulatory Act. Principal and Interest on this Tranche [    ] Bond are payable from and secured primarily by the system restoration property authorized by the Financing Order. System restoration property is known as “transition property” in the Public Utility Regulatory Act.

[through the Transition Charge Adjustment Process] . . . reduce, alter, or impair the transition charges to be imposed, collected, and remitted to financing parties, until the principal, interest, and premium, and any other charges incurred and contracts to be performed in connection with the related transition bonds have been paid and performed in full.”

Reference is made to the further provisions of this Tranche [    ] Bond set forth on the reverse hereof, which shall have the same effect as though fully set forth on the face of this Tranche [    ] Bond.

Unless the certificate of authentication hereon has been executed by the Trustee whose name appears below by manual signature, this Tranche [    ] Bond shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to the Issuer or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

REVERSE OF BOND

This Tranche [    ] Senior Secured System Restoration Bond is one of a duly authorized issue of Senior Secured System Restoration Bonds of the Issuer (herein called the “Bonds”), which are issuable in one or more Tranches, in which this Tranche [    ] Senior Secured System Restoration Bond represents an interest, including the Tranche [    ] Senior Secured System Restoration Bonds (herein called the “Tranche [    ] Bonds”), all issued and to be issued under an indenture dated as of November 25, 2009, and a supplemental indenture thereto dated as of even date therewith (such supplemental indenture, as supplemented or amended, the “Supplement” and, collectively with such indenture, as supplemented or amended, the “Indenture”), each between the Issuer and Deutsche Bank Trust Company Americas 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 Trust Estate pledged, the nature and extent of the security and the respective rights, obligations and immunities thereunder of the Issuer, the Trustee and the Bondholders. All terms used in this Tranche [    ] Bond that are defined in the Indenture, as supplemented or amended, shall have the meanings assigned to them in the Indenture.

The Tranche [    ] Bonds and the other Tranche of Bonds issued by the Issuer are and will be equally and ratably secured by the Trust Estate pledged as security therefor as provided in the Indenture or the Supplement.

The Principal of this Tranche [    ] Bond shall be payable on each Payment Date only to the extent that amounts in the Collection Account are available therefor, and only until the outstanding Principal balance thereof on such Payment Date (after giving effect to all payments of Principal, if any, made on such Payment Date) has been reduced to the Principal balance specified in the Expected Amortization Schedule which is attached to the Supplement as Schedule A, unless payable earlier because an Event of Default shall have occurred and be continuing and the Trustee or the Bondholders representing not less than a majority of the Outstanding Amount of the Bonds have declared the Bonds to be immediately due and payable in accordance with Section 5.02 of the Indenture. However, actual Principal payments may be made in less than expected amounts and at later than expected times as determined pursuant to Section 8.02(d) of the Indenture and Section 5.02 of the Supplement. The entire unpaid Principal amount of this Tranche [    ] Bond shall be due and payable on the Final Maturity Date of this Tranche [    ] Bond. Notwithstanding the foregoing, the entire unpaid Principal amount of the Bonds shall be due and payable, if not then previously paid, on the date on which an Event of Default shall have occurred and be continuing and the Trustee or the Bondholders representing a majority of the Outstanding Amount of the Bonds have declared the Bonds to be immediately due and payable in the manner provided in Section 5.02 of the Indenture. All Principal payments on the Tranche [    ] Bonds shall be made pro rata to the Tranche [    ] Bondholders entitled thereto based on the respective Principal amounts of the Bonds held by them.

Payments of Interest on this Tranche [    ] Bond due and payable on each Payment Date, together with the installment of Principal or premium, if any, due on this Tranche [    ] Bond on such Payment Date shall be made by check mailed first-class, postage prepaid, to the Person whose name appears as the Holder of this Tranche [    ] Bond in the Bond Register as of the close of business on the Record Date or in such other manner as may be provided in the Supplement, except that with respect to Tranche [    ] Bonds

A-6

registered on the Record Date in the name of a Clearing Agency, payments will be made by wire transfer in immediately available funds to the account designated by such Clearing Agency and except for the final installment of Principal and premium, if any, payable with respect to this Tranche [    ] Bond on a Payment Date which shall be payable as provided below. Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears in the Bond Register as of the applicable Record Date without requiring that this Tranche [    ] Bond be submitted for notation of payment. Any reduction in the Principal amount of this Tranche [    ] Bond (or any one or more predecessors to such Bond) effected by any payments made on any Payment Date shall be binding upon all future Bondholders of this Tranche [    ] Bond and of any Tranche [    ] Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If funds are expected to be available, as provided in the Indenture, for payment in full of the then remaining unpaid Principal amount of this Tranche [    ] Bond on a Payment Date, then the Trustee, in the name of and on behalf of the Issuer, will notify the Person who was the Holder hereof as of the preceding Record Date to such Payment Date by notice mailed no later than five days prior to such final Payment Date and shall specify that such final installment will be payable to the Holder hereof as of the Record Date immediately preceding such final Payment Date and only upon presentation and surrender of this Tranche [    ] Bond and shall specify the place where this Tranche [    ] Bond may be presented and surrendered for payment of such installment.

The Issuer shall pay Interest on overdue installments of Interest on this Tranche [    ] Bond at the Bond Rate for Tranche [    ] to the extent lawful.

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Tranche [    ] Bond may be registered in the Bond Register upon surrender of this Tranche [    ] Bond for registration of transfer at the office or agency designated by the Issuer pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder hereof or his attorney duly authorized in writing, with such signature guaranteed by an Eligible Guarantor Institution, and thereupon one or more new Tranche [    ] Bonds of any Authorized Denominations and in the same aggregate unpaid Principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any registration of transfer or exchange of this Tranche [    ] Bond, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange.

Prior to the due presentment for registration of transfer of this Tranche [    ] Bond, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name this Tranche [    ] Bond is registered (as of the day of determination) as the owner hereof for the purpose of receiving payments of Principal of and premium, if any, and Interest on this Tranche [    ] Bond and for all other purposes whatsoever, whether or not this Tranche [    ] Bond be overdue, and neither the Issuer, the Trustee nor any such agent shall be affected by notice to the contrary.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Bondholders under the Indenture at any time by the Issuer with the consent of the

A-7

Bondholders representing a majority of the Outstanding Amount of all Bonds at the time Outstanding of each Tranche to be affected. The Indenture also contains provisions permitting the Bondholders representing specified percentages of the Outstanding Amount of the Bonds, on behalf of all Bondholders, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Bondholders of this Tranche [    ] Bond (or any one or more predecessors of such Bonds) shall be conclusive and binding upon such Bondholder and upon all future Bondholders of this Tranche [    ] Bond and of any Tranche [    ] Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Tranche [    ] Bond. The Indenture also permits the Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of the Bondholders.

For so long as the Servicer and Issuer are each disregarded as an entity separate from CenterPoint Energy, Inc., a Texas corporation (“CenterPoint Energy”), under U.S. Treasury Regulations §§ 301.7701-2 and -3, each Bond Owner, by acquiring a beneficial interest, agrees to treat such Bond as indebtedness of CenterPoint Energy for federal income (and, to the extent applicable, state and local income and franchise) tax purposes unless otherwise required by appropriate taxing authorities. For any time period other than that in which the Servicer and Issuer are each disregarded as an entity separate from CenterPoint Energy or to the extent the appropriate taxing authorities require a tax treatment contrary to that described in the preceding sentence, each Bond Owner agrees to treat such Bond as indebtedness of the Issuer or such other party as is required by the appropriate taxing authority. For purposes other than federal income (and, to the extent applicable, state and local income and franchise) tax purposes, each Bond Owner is looking to the Issuer for payment of the amounts due and payable hereunder.

The term “Issuer” as used in this Tranche [    ] Bond includes any successor to the Issuer under the Indenture.

The Issuer is permitted by the Indenture, under certain circumstances, to merge or consolidate.

The Tranche [    ] Bonds are issuable only in registered form in Authorized Denominations as provided in the Indenture and the Supplement, subject to certain limitations therein set forth.

THIS TRANCHE [    ] BOND, THE INDENTURE AND THE SUPPLEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

No reference herein to the Indenture and no provision of this Tranche [    ] Bond or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the Principal of and Interest on this Tranche [    ] Bond at the times, place, and rate, and in the coin or currency herein prescribed.
