     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 of either series, in whole or in part, at its option at any time from time to time prior to October 15, 2020, in the case of the 2021 Notes (three months prior to the 2021 Maturity Date), or July 15, 2040, in the case of the 2041 Notes (six months prior to the 2041 Maturity Date), at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date plus (iii) the Make-Whole Premium, if any.

     (b) At any time on or after October 15, 2020, in the case of the 2021 Notes, or at any time on or after July 15, 2040, in the case of the 2041 Notes, the Company shall have the right to redeem the Notes of such series, in whole or in part, at its option at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date.

     (c) 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, in the case of each of the 2021 Notes and the 2041 Notes.

     (d) 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 RBS Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets, LLC or SunTrust Robinson Humphrey, 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”).

     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 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 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 of any series 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

     (b) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Note) pursuant to Rule 144 under the

Securities Act or an effective registration statement under the Securities Act, which shall be certified to the Trustee and Security Registrar upon which each may conclusively rely:

     (i) in the case of any Transfer Restricted Security represented by a certificated note, the Security Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a certificated note that does not bear the legend set forth in Section 502(a) hereof and rescind any restriction on the transfer of such Transfer Restricted Security; and

     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 January 15, 2021, and to pay interest thereon from January 11, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on January 15 and July 15 in

each year, commencing July 15, 2011, at the rate of 4.50% 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 4.50% 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, 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 January 1 or July 1 (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.

4.50% SENIOR NOTES DUE 2021
SERIES [A/B]

     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, N.A. (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 $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 prior to October 15, 2020 (three months prior to the 2021 Maturity Date) at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date plus (iii) the Make-Whole Premium, if any. At any time on or after October 15, 2020, the Company shall have the right to redeem the Securities of this series, in whole or in part, at its option at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date.

     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 January 15, 2021; 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 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 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.

     As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, 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 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 transferees. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the 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 $2,000 and any integral multiple of $1,000 in excess 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.

     By its acceptance of this Security bearing a legend restricting transfer, each Holder of this Security acknowledges the restrictions on transfer of this Security set forth in the Indenture and such legend and agrees that it will transfer this Security only as provided in the Indenture. In addition to the rights provided to Holders of this Security under the Indenture, Holders shall have all the rights set forth in that certain Registration Rights Agreement, dated as of January 11, 2011, among the Company, the Initial Purchasers and the Dealer Managers, including without limitation the right to receive Additional Interest as described in Section 2.5 thereof.

     THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

5.85% SENIOR NOTES DUE 2041
SERIES [A/B]

     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, N.A. (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.

     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 prior to July 15, 2040 (six months prior to the 2041 Maturity Date) at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date plus (iii) the Make-Whole Premium, if any. At any time on or after July 15, 2040, the Company shall have the right to redeem the Securities of this series, in whole or in part, at its option at a price equal to (i) 100% of the principal amount thereof plus (ii) accrued and unpaid interest thereon, if any, including Additional Interest, if any, to (but excluding) the Redemption Date.

     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 January 15, 2041; 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 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.
