Indenture, dated as of May 19, 2003 (the "Original Indenture" and, as hereby

     Pursuant to the terms of the Indenture, the Company desires to provide for

     Section 301 of the Original Indenture provides that various matters with
respect to any series of Securities issued under the Indenture may be
established in an indenture supplemental to the Indenture.

     Subparagraph (7) of Section 901 of the Original Indenture provides that the
Company and the Trustee may enter into an indenture supplemental to the
Indenture to establish the form or terms of Securities of any series as
permitted by Sections 201 and 301 of the Original Indenture.

Securities provided for herein, it is mutually covenanted and agreed, for the
equal and proportionate benefit of the Holders of the Securities of such series,

Date. Such interest shall be payable semiannually in arrears on February 1 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

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

system, all as more fully provided in the Indenture.

     (c) The amount of interest payable for any period shall be computed on the
basis of a 360-day year of twelve 30-day months. 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 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 5.95% 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.

     Section 401 Redemption Price.

part, at its option at any time from time to time at a price equal to (i) 100%

                                       8

<PAGE>

     (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 Banc of America
Securities LLC, Deutsche Bank Securities Inc. or J.P. Morgan Securities Inc.,
or, if such firms are unwilling or unable to make such calculation, by a
different independent investment banking institution of national standing
appointed by the Company (in any such case, an "Independent Investment Banker").

     (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 to be
redeemed, 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

                                       9

<PAGE>

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 IV 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
IV, 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.

[For as long as this Global Security is deposited with or on behalf of The
Depository Trust Company it shall bear the following legend.] Unless this
certificate is presented by an authorized representative of The Depository Trust

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 February 1, 2017, and to pay
interest thereon from February 6, 2007 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semi-annually on
February 1 and August 1 in each year, commencing August 1, 2007, at the rate of
5.95% 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 5.95% 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 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 any
day other than a Saturday, a Sunday or a day on which banking institutions in
The City of New York are authorized or required by law, regulation 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 January 15 or July 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.

                       [FORM OF REVERSE SIDE OF SECURITY]

                            CENTERPOINT ENERGY, INC.

                              5.95% NOTES DUE 2017

     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 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 $250,000,000; 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 February 1, 2017;
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.

                                       A-4

<PAGE>

     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.

     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

                                       A-5

Exhibit 10(mm)

CenterPoint Energy, Inc.

Summary of Non-employee Director Compensation

     The following is a summary of compensation paid to the non-employee directors of CenterPoint
Energy, Inc. (the “Company”) effective June 2, 2005. For additional information regarding the
compensation of the non-employee directors, please read the definitive proxy statement relating to
the Company’s 2007 annual meeting of shareholders to be filed pursuant to Regulation 14A.

	 	•	 	Annual retainer fee of $50,000 for Board membership;
	 
	 	•	 	Fee of $1,500 for each Board meeting attended;
	 
	 	•	 	Fee of $2,000 for each Audit Committee meeting attended;
	 
	 	•	 	Fee of $1,500 for each meeting of any other Board committee attended;
	 
	 	•	 	Supplemental annual retainer of $10,000 for serving as a chairman of the Audit
Committee; and
	 
	 	•	 	Supplemental annual retainer of $5,000 for serving as a chairman of any other Board
committee.

     The Chairman receives the compensation payable to other non-employee directors plus
supplemental compensation pursuant to a letter agreement with the Company incorporated by reference
to Exhibit 10(v) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.

     Stock Grants. Each non-employee director also receives an annual grant of up to 5,000 shares
of CenterPoint Energy common stock which vest in one-third increments on the first, second and
third anniversaries of the grant date. Upon the initial nomination to the Board, in addition to
the annual grant, a non-employee director may be granted a one-time grant of up to 5,000 shares of CenterPoint Energy common stock.

     Deferred Compensation Plan. Directors may elect each year to defer all or part of their
annual retainer fees and meeting fees. Directors participating in these plans may elect to receive
distributions of their deferred compensation and interest in three ways: (i) an early distribution
of either 50% or 100% of their account balance in any year that is at least four years from the
year of deferral up to the year in which they reach age 70, (ii) a lump sum distribution payable in
the year after they reach age 70 or upon leaving the Board of Directors, whichever is later, or
(iii) 15 annual installments beginning on the first of the month coincident with or next following
age 70 or upon leaving the Board of Directors, whichever is later.

     Director Benefits Plan. Non-employee directors elected to the Board before 2004 participate
in a director benefits plan under which a director who serves at least one full year will receive
an annual cash amount equal to the annual retainer (excluding any supplemental retainer) in effect
when the director terminates service. Benefits under this plan begin the January following the
later of the director’s termination of service or attainment of age 65, for a period equal to the
number of full years of service of the director.

     Executive Life Insurance Plan. Non-employee directors who were elected to the Board before
2001 participate in CenterPoint Energy’s executive life insurance plan. This plan provides
endorsement split-dollar life insurance with a death benefit equal to six times the director’s
annual retainer, excluding any supplemental retainer, with coverage continuing after the director’s
termination of service at age 65 or later. Directors elected to the Board after 2000 may not
participate in this plan.
