Such interest shall be payable semiannually in arrears, on May 1 and November 1,
of each year (each such date, an "Interest Payment Date"), commencing November
1, 2006.

      (b) The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Persons in whose names the Notes
(or one or more Predecessor Securities) are registered at the close of business

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

that any date on which interest is payable on a Note is not a Business Day, then

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 6.15% 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.

presented or surrendered for payment shall be the Corporate Trust Office of the
Trustee.

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

thereof, shall apply to the Notes.

      (b) Solely with respect to the Notes issued hereby, the first sentence of

      In case the Company or any Subsidiary shall propose to pledge, mortgage,
or hypothecate any Principal Property at any time owned by it to secure any
indebtedness, other than as permitted by paragraphs (a) to (p), inclusive, of
this Section 303, the Company shall prior thereto


give written notice thereof to the Trustee, and the Company shall or shall cause
such Subsidiary to, prior to or simultaneously with such pledge, mortgage or
hypothecation, by supplemental indenture executed and delivered to the Trustee
(or to the extent legally necessary to another trustee or additional or separate
trustee), in form satisfactory to the Trustee, effectively secure all the Notes
equally and ratably with, or prior to, such indebtedness.

      Notwithstanding the foregoing provisions of this Section 303, the Company
or a Subsidiary may issue, assume or guarantee indebtedness secured by a
mortgage which would otherwise be subject to the foregoing restrictions in an
aggregate amount which, together with all other indebtedness of the Company or a
Subsidiary secured by a mortgage which (if originally issued, assumed or
guaranteed at such time) would otherwise be subject to the foregoing
restrictions (not including indebtedness permitted to be secured under
subdivisions (a) through (p) above) and the Value of all Sale and Leaseback
Transactions in existence at such time (other than any Sale and Leaseback
Transaction which, if such Sale and Leaseback Transaction had been a lien, would
have been permitted by paragraph (i), (j) or (k) of this Section 303 and other
than Sale and Leaseback Transactions as to which application of amounts have
been made in accordance with Section 304) does not at the time of incurrence of
such indebtedness exceed 5% of Consolidated Net Tangible Assets. "Value" means,
with respect to a Sale and Leaseback Transaction, as of any particular time, the
amount equal to the greater of (1) the net proceeds from the sale or transfer of
the property leased pursuant to such Sale and Leaseback Transaction or (2) the
fair value, in the opinion of the Board of Directors, of such property at the
time of entering into such Sale and Leaseback Transaction, in either case
divided first by the number of full years of the term of the lease and then
multiplied by the number of full years of such term remaining at the time of
determination, without regard to any renewal or extension options contained in
the lease.

      For purposes of this Section 303, "Subsidiary" does not include a Project
Finance Subsidiary.

      Section 304. Restrictions on Sale and Leaseback Transactions. The Company
shall not, nor shall it permit any Subsidiary to, enter into any Sale and
Leaseback Transaction unless the net proceeds of such sale are at least equal to
the fair value (as determined by the Board of Directors) of such Principal
Property and either (a) the Company or such Subsidiary would be entitled,
pursuant to the provisions of (1) paragraph (i) or (j) of Section 303 or (2)
paragraph (k) of Section 303, to incur indebtedness secured by a lien on the
Principal Property to be leased without equally and ratably securing the Notes,
or (b) the Company shall, and in any such case the Company covenants that it
will, within 120 days of the effective date of any such arrangement, apply an
amount not less than the fair value (as so determined) of such Principal
Property (i) to the payment or other retirement of Funded Debt incurred or
assumed by the Company which ranks senior to or pari passu with the Notes or of
Funded Debt incurred or assumed by any Subsidiary (other than, in either case,
Funded Debt owned by the Company or any Subsidiary), or (ii) to the purchase at
not more than fair value (as so determined) of Principal Property (other than
the Principal Property involved in such sale). For this purpose, "Funded Debt"
means any indebtedness which by its terms matures at or is extendable or
renewable at the sole option of the obligor thereon without requiring the
consent of the obligee to a date more than 12 months after the date of the
creation of such indebtedness.



      For purposes of this Section 304, "Subsidiary" does not include a Project
Finance Subsidiary.

      Section 305. Expiration of Restrictions on Liens and Restrictions on Sale
and Leaseback Transactions. Notwithstanding anything to the contrary herein, on
the date (the "Termination Date") (and continuing thereafter) on which there
remains outstanding, in the aggregate, no more than $200,000,000 in principal
amount of Long-Term Indebtedness, the covenants of the Company set forth in
Sections 303 and 304 hereof shall terminate and the Company shall no longer be
subject to the covenants set forth in such Sections.

                                  ARTICLE FOUR

                        Optional Redemption of the Notes

      Section 401. Redemption Price.

      (a) The Company shall have the right to redeem the Notes, in whole or in
part, at its option at any time from time to time at a price equal to (i) 100%
of the principal amount thereof plus (ii) accrued and unpaid interest thereon,
if any, to but excluding the Redemption Date plus (iii) the Make-Whole Premium,
if any (collectively, the "Redemption Price").

      (b) The amount of the Make-Whole Premium with respect to any Note (or
portion thereof) to be redeemed will be equal to the excess, if any, of: (i) the
sum of the present values, calculated as of the Redemption Date, of: (A) each
interest payment that, but for such redemption, would have been payable on the
Note (or portion thereof) being redeemed on each Interest Payment Date occurring
after the Redemption Date (excluding any accrued and unpaid interest for the
period prior to the Redemption Date); and (B) the principal amount that, but for
such redemption, would have been payable on the Note (or portion thereof) being
redeemed at the Maturity Date; over (ii) the principal amount of the Note (or
portion thereof) being redeemed. The present values of interest and principal
payments referred to in clause (i) above will be determined in accordance with
generally accepted principles of financial analysis. Such present values will be
calculated by discounting the amount of each payment of interest or principal
from the date that each such payment would have been payable, but for the
redemption, to the Redemption Date at a discount rate equal to the Comparable
Treasury Yield (as defined below) plus 20 basis points.

      (c) The Make-Whole Premium shall be calculated by an independent
investment banking institution of national standing appointed by the Company;
provided, that if the Company fails to make such appointment at least 45 days
prior to the Redemption Date, or if the institution so appointed is unwilling or
unable to make such calculation, such calculation shall be made by Barclays
Capital Inc., LaSalle Financial Services, Inc. or Scotia Capital (USA) Inc., or,
if such firms are unwilling or unable to make such calculation, by an
independent investment banking institution of national standing appointed by the
Company (in any such case, an "Independent Investment Banker").

      Section 402. Make-Whole Premium Calculation.



      (a) For purposes of determining the Make-Whole Premium, "Comparable
Treasury Yield" means a rate of interest per annum equal to the weekly average
yield to maturity of United States Treasury securities that have a constant
maturity that corresponds to the remaining term to maturity of the Notes,
calculated to the nearest 1/12th of a year (the "Remaining Term"). The
Comparable Treasury Yield shall be determined as of the third Business Day
immediately preceding the applicable Redemption Date.

      (b) The weekly average yields of United States Treasury securities shall
be determined by reference to the most recent statistical release published by
the Federal Reserve Bank of New York and designated "H.15 (519) Selected
Interest Rates" or any successor release (the "H.15 Statistical Release"). If
the H.15 Statistical Release sets forth a weekly average yield for United States
Treasury securities having a constant maturity that is the same as the Remaining
Term, then the Comparable Treasury Yield shall be equal to such weekly average
yield. In all other cases, the Comparable Treasury Yield shall be calculated by
interpolation, on a straight-line basis, between the weekly average yields on
the United States Treasury securities that have a constant maturity closest to
and greater than the Remaining Term and the United States Treasury securities
that have a constant maturity closest to and less than the Remaining Term (in
each case as set forth in the H.15 Statistical Release). Any weekly average
yields so calculated by interpolation shall be rounded to the nearest 1/100th of
1%, with any figure of 1/200th of 1% or above being rounded upward. If weekly
average yields for United States Treasury securities are not available in the
H.15 Statistical Release or otherwise, then the Comparable Treasury Yield shall
be calculated by interpolation of comparable rates selected by the Independent
Investment Banker.

      Section 403. Partial Redemption. If the Company redeems the Notes in part
pursuant to this Article Four, the Trustee shall select the Notes to be redeemed
on a pro rata basis or by lot or by such other method that the Trustee in its
sole discretion deems fair and appropriate. The Company shall redeem Notes
pursuant to this Article Four in multiples of $1,000 in original principal
amount. A new Note in principal amount equal to the unredeemed portion of the
original Note shall be issued upon cancellation of the original Note.

      Section 404. Notice of Optional Redemption. If the Company elects to
exercise its right to redeem all or some of the Notes pursuant to this Article
Four, the Company or the Trustee shall mail a notice of such redemption to each
Holder of a Note that is to be redeemed not less than 30 days and not more than
60 days before 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.

                                  ARTICLE FIVE

                                    REMEDIES

      Section 501. Additional Events of Default; Acceleration of Maturity.

      (a) Solely with respect to the Notes issued hereby, Section 501(7) of the
Original Indenture is hereby deleted in its entirety, and the following is
substituted in lieu thereof as an



"Event of Default" in addition to the other events set forth in Section 501 of
the Original Indenture:

            "(7) the default by the Company or any Subsidiary, other than a
            Project Finance Subsidiary, in the payment, when due, after the
            expiration of any applicable grace period, of principal of
            indebtedness for money borrowed, other than Non-Recourse Debt, in
            the aggregate principal amount then outstanding of $50 million or
            more, or acceleration of any indebtedness for money borrowed in such
            aggregate principal amount so that it becomes due and payable prior
            to the date on which it would otherwise have become due and payable
            and such acceleration is not rescinded or such default is not cured
            within 30 days after there has been given, by registered or
            certified mail, to the Company by the Trustee or to the Company and
            the Trustee by the holders of at least 25% in principal amount of
            Notes written notice specifying such default and requiring the
            Company to cause such acceleration to be rescinded or such default
            to be cured and stating that such notice is a "Notice of Default"
            under the Indenture;".

      (b) Solely with respect to the Notes issued hereby, the first paragraph of
Section 502 of the Original Indenture is hereby deleted in its entirety, and the
following is substituted in lieu thereof:

            "If an Event of Default (other than an Event of Default specified in
            Section 501(5) or 501(6)) with respect to the Notes at the time
            Outstanding occurs and is continuing, then in every such case the
            Trustee or the Holders of not less than 25% in principal amount of
            the Notes Outstanding may declare the principal amount of all the
            Notes to be due and payable immediately, by a notice in writing to
            the Company (and to the Trustee if given by Holders), and upon any
            such declaration such principal amount (or specified amount) shall
            become immediately due and payable. If an Event of Default specified
            in Section 501(5) or 501(6) with respect to the Notes at the time
            Outstanding occurs and is continuing, the principal amount of all
            the Notes shall automatically, and without any declaration or other
            action on the part of the Trustee or any Holder, become immediately
            due and payable."

      Section 502. Expiration of Additional Events of Default. Notwithstanding
anything to the contrary herein, on the Termination Date (and continuing
thereafter), the event of default of the Company set forth in Section 501(a)
hereof shall terminate and the Company shall no longer be subject to such event
of default.



                                   ARTICLE SIX

[For as long as this Global Security is deposited with or on behalf of The

      CENTERPOINT ENERGY RESOURCES CORP., a corporation duly organized and
existing under the laws of the State of Delaware formerly known as NorAm Energy
Corp. (herein called the "Company", which term includes any successor Person
under the Indenture hereinafter referred to), for value received, hereby
promises to pay to _______________, or registered assigns, the principal sum of
____________________ Dollars on May 1, 2016, and to pay interest thereon from
May 18, 2006 or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, semi-annually on May 1 and November 1 in each
year, commencing November 1, 2006, at the rate of 6.15% per annum, until the
principal hereof is paid or made available for payment, provided that any
principal and premium, and any such installment of interest, which is overdue
shall bear interest at the rate of 6.15% per annum (to the extent permitted by
applicable 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. The amount
of

                                       A-1



interest payable for any period shall be computed on the basis of twelve 30-day
months and a 360-day year. The amount of 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 this Security 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. A "Business Day" shall mean, when used with respect to any
Place of Payment, each Monday, Tuesday, Wednesday, Thursday and Friday which is
not a day on which banking institutions in that Place of Payment are authorized
or obligated by law or executive order to close. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the April 15 or
October 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. 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 be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on a Special Record Date for the payment of such Defaulted Interest to be fixed
by the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such Special Record Date, or 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 Securities of
this series 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 said
Indenture.

      Payment of the principal of (and premium, if any) and any such interest on
this Security will be made at the Corporate Trust Office of the Trustee, 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; provided, however, that 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.

      Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

      Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

authenticated and delivered. This Security is one of the series designated on
the face hereof, initially limited in aggregate principal amount to
$325,000,000; provided, however, that the authorized aggregate principal amount
of the Securities may be increased above such amount by a Board Resolution to
such effect.

      The Company shall have the right to redeem the Securities of this series,
in whole or in part, at its option at any time from time to time at a price
equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid
interest thereon, if any, to (but excluding) the Redemption Date plus (iii) the
Make-Whole Premium, if any.

      The amount of the Make-Whole Premium with respect to any Security of this
Series (or portion thereof) to be redeemed will be equal to the excess, if any,
of: (i) the sum of the present values, calculated as of the Redemption Date, of:
(A) each interest payment that, but for such redemption, would have been payable
on the Security of this series (or portion thereof) being redeemed on each
Interest Payment Date occurring after the Redemption Date (excluding any accrued
and unpaid interest for the period prior to the Redemption Date); and (B) the
principal amount that, but for such redemption, would have been payable on the
Security of this series (or portion thereof) being redeemed at May 1, 2016; over
(ii) the principal amount of the Security of this series (or portion thereof)
being redeemed. The present values of interest and principal payments referred
to in clause (i) above will be determined in accordance with generally accepted
principles of financial analysis. Such present values will be calculated by
discounting the amount of each payment of interest or principal from the date
that each such payment would have been payable, but for the redemption, to the
Redemption Date at a discount rate equal to the Comparable Treasury Yield (as
defined below) plus 20 basis points.

      For purposes of determining the Make-Whole Premium, "Comparable Treasury
Yield" means a rate of interest per annum equal to the weekly average yield to
maturity of United States Treasury securities that have a constant maturity that
corresponds to the remaining term to maturity of the Securities of this series,
calculated to the nearest 1/12th of a year (the "Remaining Term"). The
Comparable Treasury Yield shall be determined as of the third Business Day
immediately preceding the Redemption Date.

      The weekly average yields of United States Treasury securities shall be
determined by

                                       A-4



reference to the most recent statistical release published by the Federal
Reserve Bank of New York and designated "H.15 (519) Selected Interest Rates" or
any successor release (the "H.15 Statistical Release"). If the H.15 Statistical
Release sets forth a weekly average yield for United States Treasury securities
having a constant maturity that is the same as the Remaining Term, then the
Comparable Treasury Yield shall be equal to such weekly average yield. In all
other cases, the Comparable Treasury Yield shall be calculated by interpolation,
on a straight-line basis, between the weekly average yields on the United States
Treasury securities that have a constant maturity closest to and greater than
the Remaining Term and the United States Treasury securities that have a
constant maturity closest to and less than the Remaining Term (in each case as
set forth in the H.15 Statistical Release). Any weekly average yields so
calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with
any figure of 1/200th of 1% or above being rounded upward. If weekly average
yields for United States Treasury securities are not available in the H.15
Statistical Release or otherwise, then the Comparable Treasury Yield shall be
calculated by interpolation of comparable rates selected by the Independent
Investment Banker.

      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.

      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 25% 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

herein prescribed.

Company and the Security Registrar duly executed by, the Holder hereof or his
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

Trustee nor any such agent shall be affected by notice to the contrary.

      The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple 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.

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

      THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND
