RECITALS OF THE ISSUER

The Issuer has duly authorized the creation of an issue of its 4.10% Senior Bonds due September 15, 2042 (the “Securities”) of substantially the tenor and amount hereinafter set forth, and to provide therefor the Issuer has duly authorized the execution and delivery of this Agreement.

All things necessary to make the Securities, when executed by the Issuer and authenticated and delivered hereunder and duly issued by the Issuer, the valid and legally binding obligations of the Issuer, and to make this Agreement a valid and legally binding agreement of the Issuer, in accordance with their and its terms, have been done.

1.The Securities.

(a)General. The initial aggregate principal amount of Securities issued under this Agreement will be $250,000,000. The aggregate principal amount of Securities which may be authenticated and delivered under this Agreement is unlimited, including without limitation, Securities authenticated and delivered upon registration of transfer, or in exchange for, or in lieu of other Securities pursuant to the provisions of this Agreement or the Securities. The Securities and any additional Securities subsequently issued under this Agreement will be treated as a single class for all purposes under this Agreement.

The Securities shall be known and designated as the “4.10% Senior Bonds due 2042” of the Issuer. The Securities will be unsecured, direct, unconditional and general obligations of the Issuer and will rank paripassuwith all other unsecured and unsubordinated indebtedness of the Issuer.

(b)Form of Securities; Denominations of Securities. The Securities will be issued in registered form without coupons in substantially the form, and including the terms, provided for herein and on Exhibit A. The Securities shall be executed manually or in facsimile on behalf of the Issuer by its Chairman of the Board, President or a Vice President and by its Secretary or an Assistant Secretary (the “Authorized Officers”), notwithstanding that such officers, or any one of them, shall have ceased, for any reason, to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. The Securities may also have such additional provisions, omissions, variations or substitutions as are not inconsistent with the provisions of this Agreement and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with any law or with any rules made pursuant thereto or with the rules of any securities exchange or governmental agency or as may, consistently herewith, be determined by the Authorized Officers of the Issuer executing such Securities, as conclusively evidenced by their execution of such Securities. All of the Securities shall be otherwise substantially identical except as to denominations of Securities and as provided herein.

(i) Except as otherwise set forth in this Agreement, the Securities offered and sold in their initial resale distribution to a qualified institutional buyer (as defined in Rule 144A (“Rule 144A”) under the Securities Act of 1933, as amended (the “Act”), each a “QIB”) in reliance on Rule 144A (“Rule 144A Securities”) shall initially be issued in the form of one or more Global Securities (as defined in Section 1(e) hereof) in definitive, fully registered form, substantially in the form set forth on Exhibit A, with such applicable legends as are provided for herein and on Exhibit A, and in minimum denominations of $2,000 and in integral multiples of $1,000 in excess of $2,000. Such Global Securities shall be duly executed by the Issuer and authenticated by the Fiscal Agent as hereinafter provided, and deposited with the U.S. Depository (as defined in Section 1(e) hereof). Until such time as the Holding Period (as defined below) shall have terminated, each such Security shall be referred to as a “Rule 144A Global Security.” The aggregate principal amount of any Rule 144A Global Security may be adjusted by endorsements to Schedule A on the reverse thereof in any situation where adjustment is permitted or required by this Agreement or provided for on Exhibit A. Unless the Issuer determines otherwise in accordance with applicable law, the legend setting forth transfer restrictions shall be removed or deemed removed from a Rule 144A Security in accordance with the procedures set forth in Section 1(d) after such time as the applicable Holding Period shall have terminated, and each such Security shall thereafter be held as an unrestricted Security. As used herein, the term “Holding Period,” with respect to Rule 144A Securities, means the period referred to in Rule 144(d) under the Act or any successor provision thereto (“Rule 144(d)”) and as may be amended or revised from time to time, beginning from the later of (i) the original issue date of such Securities or (ii) the last date on which the Issuer or any affiliate of the Issuer was the beneficial owner of such Securities (or any predecessor thereof).

(ii) Except as otherwise set forth in this Agreement, Securities offered and sold in reliance on Regulation S under the Act (“Regulation S”) will be issued initially in the form of one or more temporary Global Securities in the form provided for herein and on Exhibit A, with such applicable legends as are provided for herein and on Exhibit A, and in minimum denominations of $2,000 and in integral multiples of $1,000 in excess of $2,000 equal to the outstanding principal amount of the Securities initially sold in reliance on Rule 903 of Regulation S under the Act (the “Regulation S Temporary Global Securities”).

(“Clearstream”), shall be duly executed by the Issuer and authenticated by the Fiscal Agent as hereinafter provided. Following the termination of the Distribution Compliance Period (as defined below) and upon the receipt by the Fiscal Agent of:

NY3667693.72

a.a written certificate from the U.S. Depository, together with copies of certificates from Euroclear and Clearstream, certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Securities (except to the extent of any beneficial owners thereof who acquired an interest therein during the Distribution Compliance Period pursuant to another exemption from registration under the Act and who will take delivery of a beneficial ownership interest in a Rule 144A Global Security or a Restricted Definitive Security (as defined below), all as contemplated by Section 5(d) hereof); and

b.a certificate signed by the Authorized Officers (“Officers' Certificate”),

beneficial interests in the Regulation S Temporary Global Securities will be exchanged for beneficial interests in a permanent global Security in the form provided for herein and on Exhibit A, issued in a denomination equal to the outstanding principal amount of the Regulation S Temporary Global Securities (the “Regulation S Permanent Global Securities”) pursuant to the rules and regulations of the U.S. Depository, Euroclear or Clearstream, as applicable, in each case pertaining to beneficial interests in Global Securities (“Applicable Procedures”). Simultaneously with the authentication of the Regulation S Permanent Global Securities, the Fiscal Agent will cancel the Regulation S Temporary Global Securities. As used herein, “Regulation S Global Securities” means the Regulation S Temporary Global Securities or the Regulation S Permanent Global Securities, as applicable.

The aggregate principal amount of the Regulation S Temporary Global Securities and the Regulation S Permanent Global Securities may be adjusted by endorsements to Schedule A on the reverse thereof in any situation where adjustment is permitted or required by this Agreement. As used herein, the term “Distribution Compliance Period,” with respect to Regulation S Securities, means the period of 40 consecutive days beginning on and including the later of (i) the date on which interests in such Securities are offered to Persons (as defined below) other than distributors (as defined in Regulation S) and (ii) the original issue date of such Securities. Except as otherwise provided in this Agreement, no Regulation S Global Security shall be issued except as provided in this paragraph to evidence Securities offered and sold in reliance on Regulation S. Unless the Issuer determines otherwise in accordance with applicable law, the legend setting forth transfer restrictions shall be removed or deemed removed from a Regulation S Security in accordance with the procedures set forth in Section 1(d) hereof, and each such Security shall thereafter be held as an unrestricted Security. As used herein, “Person” means any individual, corporation, limited liability company, partnership, joint venture, association, joint-stock company, trust, unincorporated organization or government or any agency or political subdivision thereof.

The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Securities and the Regulation S PermanentGlobal Securities that are held by Agent Members (as defined in Section 1(e)) through Euroclear or Clearstream.

NY3667693.73

(iii) Except as otherwise provided in this Agreement, Securities offered and sold in their initial resale distribution to purchasers who are institutional “accredited investors” as described in Rule 501(a)(1), (2), (3) or (7) under the Act and who are not QIBs shall be issued in the form of fully registered, definitive, physical certificates, substantially in the form set forth herein and on Exhibit A, with such applicable legends as are provided for on Exhibit A, and in minimum denominations of $200,000 and in integral multiples of $1,000 in excess of $200,000 (such securities are herein referred to as “Restricted Definitive Securities”). Unless the Issuer determines otherwise in accordance with applicable law, the legend setting forth transfer restrictions shall be removed or deemed removed from a Restricted Definitive Security in accordance with the procedures set forth in Section 1(d) after such time as the applicable Holding Period shall have terminated, and each such Security shall thereafter be held as an unrestricted Security. As used herein, the term “Holding Period,” with respect to Restricted Definitive Securities, means the period referred to in Rule 144(d) or any successor provision thereto and as may be amended or revised from time to time, beginning from the later of (i) the original issue date of such Securities or (ii) the last date on which the Issuer or any affiliate of the Issuer was the beneficial owner of such Securities (or any predecessor thereof).

(c)Temporary Securities. Until definitive Securities are prepared, the Issuer may execute, and there shall be authenticated and delivered in accordance with the provisions of Section 3 hereof (in lieu of definitive printed Securities), temporary Securities. Such temporary Securities may be in registered global form. Such temporary Securities shall be subject to the same limitations and conditions and entitled to the same rights and benefits as definitive Securities, except as provided herein or therein. Temporary Securities shall be exchangeable for definitive Securities, when such definitive Securities are available for delivery; and upon the surrender for exchange of such temporary Securities, the Issuer shall execute and there shall be authenticated and delivered, in accordance with the provisions of Sections 6 and 7 hereof, in exchange for such temporary Securities, a like aggregate principal amount of definitive Securities of like tenor. The Issuer shall pay all charges, including (without limitation) stamp and other taxes and governmental charges, incident to any exchange of temporary Securities for definitive Securities. All temporary Securities shall be identified as such and shall describe the right of the holder thereof to effect an exchange for definitive Securities and the manner in which such an exchange may be effected.

(d)Legends. Securities shall be stamped or otherwise be imprinted with the legends set forth on the face of the text of the Securities attached as Exhibit A, including any legend provided for pursuant to Section 1(e) hereof. The legends so provided on the face of the text of the Securities may be removed from any Security, upon written order signed in the name of the Issuer by the Authorized Officers and delivered to the Fiscal Agent (“Order”), (i) one year from the later of issuance of the Security or the date such Security (or any predecessor) was last acquired from an “affiliate” of the Issuer within the meaning of Rule 144 (“Rule 144”) under the Act or (ii) in connection with a sale made pursuant to the volume (and other restrictions) of Rule 144 following one year from such time, provided that, if the legend is removed and the Security is subsequently held by such an affiliate of the Issuer, the legend shall be reinstated. Any legends provided pursuant to Section 1(e) hereof may be removed in the event the applicable Global Securities cease to be Global Securities in accordance with Section 5 hereof.

NY3667693.74

(e)Book-Entry Provisions. Subject to the other provisions of this Section 1, the Securities may be issued initially in the form of one or more registered global Securities (“Global Securities”) deposited with or on behalf of a depository located in the United States, which initially shall be The Depository Trust Company together with its nominee Cede & Co. (the “U.S. Depository”), that (i) shall be registered in the name of the U.S. Depository for such Global Security or Securities or the nominee of such U.S. Depository, (ii) shall be delivered by the Fiscal Agent to such U.S. Depository or pursuant to such U.S. Depository's instruction and (iii) shall bear a legend substantially similar to the following:

THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE U.S. DEPOSITORY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE FISCAL AGENCY AGREEMENT, AND NO TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE U.S. DEPOSITORY TO A NOMINEE OF THE U.S. DEPOSITORY OR BY A NOMINEE OF THE U.S. DEPOSITORY TO THE U.S. DEPOSITORY OR ANOTHER NOMINEE OF THE U.S. DEPOSITORY OR BY THE U.S. DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR U.S. DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR U.S. DEPOSITORY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES.

UNLESS THIS GLOBAL SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE U.S. DEPOSITORY TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE IS ISSUED IN THE NAME OR NAMES AS DIRECTED IN WRITING BY THE U.S. DEPOSITORY, ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL IN AS MUCH AS THE REGISTERED HOLDER HEREOF, THE U.S. DEPOSITORY, HAS AN INTEREST HEREIN.”

Members of, or direct or indirect participants in, the U.S. Depository (“Agent Members”) shall have no rights under this Agreement with respect to any Global Security held on their behalf by the U.S. Depository or under the Global Security, and such U.S. Depository may be treated by the Issuer, the Fiscal Agent, and any agent of the Issuer or the Fiscal Agent as the owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Fiscal Agent, or any agent of the Issuer or the Fiscal Agent from giving effect to any written certification, proxy or other authorization furnished by the U.S. Depository or impair, as between the U.S. Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Security.

So long as the U.S. Depository or its nominee is the registered holder of the Securities, the U.S. Depository or such nominee will for all purposes of the Securities and this Agreement be considered the sole owner or holder of such Securities. Until such time as definitive Securities may be issued, beneficial owners of Securities will not be entitled to have Securities registered in their names, will not receive or be entitled to receive physical delivery of Securities in definitive form, and will not be considered the owners or holders thereof under this Agreement for any purpose.

The Issuer initially appoints the Fiscal Agent to serve as custodian for the Global Securities.

NY3667693.76

4.Payment and Cancellation.

(a)Payment. Subject to the following provisions, the Issuer shall provide to the Fiscal Agent in funds available on or prior to each date on which a payment of principal of or any interest on the Securities shall become due, as set forth in the text of the Securities, such amount, in such coin or currency, as is necessary to make such payment, and the Issuer hereby authorizes and directs the Fiscal Agent from funds so provided to it to make or cause to be made payment of the principal of and interest on, as the case may be, the Securities set forth herein and in the text of the Securities. The Fiscal Agent shall arrange directly with any Paying Agent who may have been appointed pursuant to the provisions of Section 2 hereof for the payment from funds so paid by the Issuer of the principal of and interest on the Securities as set forth herein and in the text of the Securities. Notwithstanding the foregoing, the Issuer may provide directly to a Paying Agent funds for the payment of the principal thereof and premium and interest, if any, payable thereon under an agreement with respect to such funds containing substantially the same terms and conditions set forth in this Section 4(a) and in Section 9(b) hereof; and the Fiscal Agent shall have no responsibility with respect to any funds so provided by the Issuer to any such Paying Agent.

Any interest on the Securities shall be paid, unless otherwise provided in the text of the Securities, to the Persons in whose names such Securities are registered on the register maintained pursuant to Section 7 hereof at the close of business on the record dates designated in the text of the Securities (the “registered holders”). Payments of principal of Securities shall be payable against surrender thereof at the Corporate Trust Office or office of an agent of the Fiscal Agent and at the offices of such other Paying Agents as shall have been appointed pursuant to Section 2 hereof. Payments of principal shall be made against surrender of Securities, and payments of interest on Securities shall be made, in accordance with the foregoing and subject to applicable laws and regulations, by check mailed on or before the due date for such payment to the Person entitled thereto at such Person's address appearing on the register of the Securities maintained pursuant to Section 7 hereof, or, in the case of payments of principal, to such other address as the registered holder shall provide in writing at the time of such surrender; provided, however, that such payments may be made, in the case of a registered holder of greater than $1,000,000 aggregate principal amount of Securities, by wire transfer to an account maintained by the payee with a bank if such registered holder so elects by giving notice to the Fiscal Agent, not less than 15 days (or such fewer days as the Fiscal Agent may accept at its discretion) prior to the date of the payments to be obtained, of such election and of the account to which payment is to be made.

(b)Cancellation. All Securities delivered to the Fiscal Agent (or any other Agent appointed pursuant to Section 2 hereof) for payment, registration of transfer or exchange as herein or in the Securities provided shall be forwarded to the Fiscal Agent by the Agent to which they are delivered. All such Securities shall be canceled and disposed of by the Fiscal Agent or such other Person as may be jointly designated by the Issuer and the Fiscal Agent, which shall thereupon furnish certificates of such disposal to the Issuer upon the Issuer's request.

NY3667693.77

5.Transfer and Exchange of Securities.

(a)Transfers of Global Securities as Such. Except as otherwise expressly set forth in this Agreement or any amendment hereto, a Global Security representing all or a portion of the Securities may not be transferred in global form, except as a whole (i) by the U.S. Depository to a nominee of such U.S. Depository, (ii) by a nominee of such U.S. Depository to such U.S. Depository or another nominee of such U.S. Depository or (iii) by such U.S. Depository or any such nominee to a successor U.S. Depository or a nominee of such successor U.S. Depository.

(b)Exchanges of Global Securities for Definitive Securities. A Global Security shall be exchangeable, in whole but not in part, for definitive Securities if (a) the U.S. Depository notifies the Issuer that it is unwilling or unable to continue to hold book-entry interests in such Global Security or the U.S. Depository at any time ceases to be a “clearing agency” registered as such under the Exchange Act of 1934, as amended (the “Exchange Act”), and, in either case, a successor is not appointed by the Issuer within 120 days, (b) while a Global Security is a restricted Security the book-entry interests in such Global Security cease to be eligible for the U.S. Depository's services because the Securities are neither (i) rated in one of the top four categories by a nationally recognized statistical rating organization nor (ii) included within a Self-Regulatory Organization system approved by the Securities and Exchange Commission (the “Commission”) for the reporting of quotation and trade information of securities eligible for transfer pursuant to Rule 144A, such as the PORTAL system, (c) the U.S. Depository for Securities notifies the Issuer that it is unwilling or unable to continue as U.S. Depository with respect to such Global Security and no successor is appointed within 120 days or (d) the Issuer in its sole discretion executes and delivers to the Fiscal Agent an Officers' Certificate providing that such Global Security shall be so exchangeable; provided, however, that in no event shall the Regulation S Temporary Global Securities be exchanged by the Issuer for definitive Securities prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the Transfer Agent of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Act. Securities so issued in exchange for any such Global Security shall have the same interest rate, if any, and maturity and have the same terms as such Global Security, in authorized denominations and in the aggregate having the same principal amount as such Global Security and registered in such names as the U.S. Depository for such Global Security shall direct. Upon such exchange, the surrendered Global Security shall be cancelled by the Fiscal Agent.

A Global Security shall be exchangeable, in whole or in part, for definitive registered Securities if there shall have occurred and be continuing an event of default (as set forth in paragraph 7 of the Securities) and the registered holder, in such circumstances, shall have requested in writing that all or a part of the Global Security be exchanged for one or more definitive Securities (an “Optional Definitive Security Request”), provided, however, that in no event shall the Regulation S Temporary Global Securities be exchanged by the Issuer for definitive registered Securities prior to (x) the expiration of the Distribution Compliance Period and (y) the receipt by the Transfer Agent of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Act. Upon any such surrender, (i) the Issuer shall execute and the Fiscal Agent shall authenticate and deliver without charge to each Person specified by the U.S. Depository, in exchange for such Person's beneficial interest in the Global Security, a new Security or Securities in definitive registered form having the same interest rate, if any, and maturity and having the same terms as such Global Security, in any authorized denomination requested by such Person and in an aggregate principal amount equal to such Person's beneficial interest in the Global Security, and (ii) if the Global Security is being exchanged (x) as a whole, then the surrendered Global Security shall be cancelled by the Fiscal Agent, or (y) in part, then the principal amount of the surrendered Global Security shall be reduced by an endorsement on Schedule A thereto in the appropriate amount.

NY3667693.78

Unless otherwise provided by the Issuer, definitive Securities issued in exchange for a Global Security pursuant to this Section 5(b) shall be issued only in registered form and shall be registered in such names and in such authorized denominations as the U.S. Depository for such Global Security, pursuant to instructions of its Agent Members or otherwise, shall instruct the Fiscal Agent. The Fiscal Agent shall deliver such Securities to the Persons in whose names such Securities are so registered.

(c)Beneficial Interests. Subject to the provisions herein, beneficial interests in a Global Security may be transferred in any manner consistent with the Applicable Procedures.

(d)Special Provisions Regarding Transfer of Beneficial Interests in a Regulation S Global Security. The transfer of beneficial interests in a Regulation S Global Security shall be effected in a manner not inconsistent with the following provisions:

(i) Transfer Through a Rule 144A Global Security. If the holder of a beneficial interest in a Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in a Rule 144A Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section 5(d)(i), provided, however, that prior to the expiration of the Distribution Compliance Period, transfers of beneficial interests in the Regulation S Temporary Global Securities may not be made to a U.S. person (as defined under Regulation S) or for the account or benefit of a U.S. person (other than an initial purchaser). Upon receipt by the U.S. Depository of the instructions, order and certificate set forth below, the U.S. Depository shall promptly forward the same to the Transfer Agent at the Corporate Trust Office. Upon receipt by the Transfer Agent from the U.S. Depository at the Corporate Trust Office of (1) written instructions given in accordance with the Applicable Procedures from an Agent Member directing the U.S. Depository to cause to be credited to a specified Agent Member's account a beneficial interest in the Rule 144A Global Security equal to that of the beneficial interest in the Regulation S Global Security to be so transferred, (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member to be credited with, and the account of the Agent Member held for Euroclear or Clearstream to be debited for, such beneficial interest, and (3) a certificate substantially in the form set forth in or contemplated by Exhibit B given by the transferor of such beneficial interest, the Transfer Agent, shall (A) reduce the principal amount of the Regulation S Global Security, and increase the principal amount of the Rule 144A Global Security, in each case by an amount equal to the principal amount of the beneficial interest in the Regulation S Global Security to be so transferred, as evidenced by appropriate endorsements on Schedule A of the respective Global Securities, and (B) instruct the U.S. Depository, (x) to make corresponding reductions and increases in the amounts represented by the respective Global Securities and (y) to cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security having a principal amount equal to the amount by which the principal amount of the Regulation S Global Security was reduced upon such transfer.

Delivery of a beneficial interest in the Regulation S Global Security may not be taken in the form of a beneficial interest in the Rule 144A Global Security if immediately prior to the contemplated transfer no Rule 144A Global Security is then Outstanding (as defined in Section 12(c) hereof).

NY3667693.79

(c)Successors. In case at any time the Fiscal Agent or any Paying Agent in respect of the Securities (if such Paying Agent is the only Paying Agent located in a place where, by the terms of the Securities or this Agreement, the Issuer is required to maintain a Paying Agent) shall resign, or shall be removed, or shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or shall file a voluntary petition in bankruptcy or make an assignment for the benefit of its creditors or consent to the appointment of a receiver of all or any substantial part of its property, or shall admit in writing its inability to pay or meet its debts as they severally mature, or if a receiver of it or of all or any substantial part of its property shall be appointed, or if an order of any court shall be entered approving any petition filed by or against it under the provisions of the Federal Bankruptcy Act or under the provisions of any similar legislation, or if a receiver of it or its property shall be appointed, or if any public officer shall take charge or control of it or of its property or affairs, for the purpose or rehabilitation, conservation or liquidation, a successor Fiscal Agent or Paying Agent, as the case may be, qualified as aforesaid, shall be appointed by the Issuer by an instrument in writing, filed with the successor Fiscal Agent or Paying Agent, as the case may be, and the predecessor Fiscal Agent or Paying Agent, as the case may be. Upon the appointment as aforesaid of a successor Fiscal Agent or Paying Agent, as the case may be, and acceptance by such successor of such appointment, the Fiscal Agent or Paying Agent, as the case may be, so succeeded shall cease to be Fiscal Agent or Paying Agent, as the case may be, hereunder. If no successor Fiscal Agent or other Paying Agent, as the case may be, shall have been so appointed by the Issuer and shall have accepted appointment as hereinafter provided, and, in the case of such other Paying Agent, if such other Paying Agent is the only Paying Agent located in a place where, by the terms of the Securities or this Agreement, the Issuer is required to maintain a Paying Agent, then any holder of a Security who has been a bona fide holder of a Security for at least six (6) months, on behalf of such holder and all others similarly situated, or the Fiscal Agent may petition any court of competent jurisdiction at the expense of the Issuer for the appointment of a successor agent. The Issuer shall give prompt written notice to each other Paying Agent of the appointment of a successor Fiscal Agent.

(e)Merger, Consolidation, etc. Any corporation into which the Fiscal Agent hereunder may be merged, or any corporation resulting from any merger or consolidation to which the Fiscal Agent shall be a party, or any corporation to which the Fiscal Agent shall sell or otherwise transfer all or substantially all of the corporate trust business of the Fiscal Agent, provided that it shall be qualified as aforesaid, shall be the successor Fiscal Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto.

It shall not be necessary for the consent of the holders of Securities to approve the particular form of any proposed modification, amendment, supplement, request, demand, authorization, direction, notice, consent, waiver or other action, but it shall be sufficient if such consent shall approve the substance thereof.

In entering into any amendment hereof, the Fiscal Agent shall receive, and may conclusively rely on, an opinion of counsel that such amendment is authorized or permitted by the terms of this Agreement.

NY3667693.724

New Securities modified to conform, in the opinion of the Fiscal Agent and the Issuer, to any such modification, amendment, supplement, request, demand, authorization, direction, notice, consent, waiver or other action may be prepared by the Issuer, authenticated by the Fiscal Agent (or any authenticating agent appointed pursuant to Section 3 hereof) and delivered in exchange for Outstanding Securities.

For this purpose, such Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the Outstanding Securities and to have satisfied all its other obligations under such Securities and this Agreement insofar as the Securities are concerned (and the Issuer and the Fiscal Agent shall execute proper instruments acknowledging the same), except for the following, which shall survive until otherwise terminated or discharged hereunder: (i) the rights of holders of the Securities to receive, solely from the trust fund described in Section 15(d) and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and any interest on the Securities when such payments are due, (ii) the Issuer's obligations with respect to the Securities under Sections 1(d), 2, 4, 6, 7, 8(a), 8(b) and 10 of this Agreement and paragraphs 3, 4, 6, 10 (insofar as it relates to Sections 8(a) and 8(b) of this Agreement), 11 and 12 of the Securities and (iii) this Section 15.

Upon the Issuer's exercise of the option provided in Section 15(a) applicable to this Section 15(c), the Issuer shall be released from its obligations under paragraphs 7(iii), 8, and 9(a)(iii) of the Securities on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of the Issuer's obligations shall be unaffected thereby.

(d)Conditions to Defeasance and Covenant Defeasance. The following shall be the conditions to application of either Section 15(b) or Section 15(c) to the then Outstanding Securities:

(i) The Issuer shall irrevocably have deposited or caused to be deposited with a trustee, who may be the Fiscal Agent and who shall agree to comply with the provisions of this Section 15 applicable to it (the “Defeasance Trustee”), as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the holders of the Securities, (A) money in an amount, or (B) U.S. Government Obligations and/or Eligible Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Defeasance Trustee, to pay and discharge, and which shall be applied by the Defeasance Trustee to pay and discharge, the principal of, premium, if any, and each installment of interest on the Securities not later than one day before the stated maturity of such principal or installment of interest in accordance with the terms of this Agreement and of the Securities. For this purpose: “U.S. Government Obligations” means securities that are (x) direct obligations of the United States of America for the payment of which its full faith and credit are pledged or (y) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depository receipt issued by a bank (as defined in Section 3(a)(2) of the Act) as custodian with respect to any such U.S. Government Obligation or a specific payment of principal of or interest on any such U.S. Government Obligation held by such custodian for the account of the holder of such depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such depository receipt; and “Eligible Obligations” means interest bearing obligations as a result of the deposit of which the Securities are rated in the highest generic long-term debt rating category assigned to legally defeased debt by one or more nationally recognized rating agencies.

NY3667693.727

(ii) In the case of an election under Section 15(b), the Issuer shall have delivered to the Defeasance Trustee an opinion of counsel stating that (x) the Issuer has received from, or there has been published by, the U.S. Internal Revenue Service a ruling, or (y) since the date of this Agreement there has been a change in the applicable U.S. Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the Outstanding Securities will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to U.S. Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred.

(iii) In the case of an election under Section 15(c), the Issuer shall have delivered to the Defeasance Trustee an opinion of counsel to the effect that the holders of the Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and Covenant Defeasance and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and Covenant Defeasance had not occurred.

(iv) No event of default under paragraph 7 of the Securities or event which with notice or lapse of time or both would become such an event of default shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs 7(iv) and (v) of the Securities are concerned, at any time during the period ending on the 121st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(v) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of or constitute a default under, any other agreement or instrument to which the Issuer is a party or by which it is bound.

(vi) The Issuer shall have delivered to the Fiscal Agent and the Defeasance Trustee an Officers' Certificate and an opinion of counsel, each stating that all conditions precedent provided for relating to either the Defeasance under Section 15(b) or the Covenant Defeasance under Section 15(c) (as the case may be) have been complied with.

(vii) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company as defined in the Investment Company Act of 1940, as amended, or such trust shall be qualified under such act or exempt from regulation thereunder.

NY3667693.728

(e)Deposit in Trust; Miscellaneous. All money, U.S. Government Obligations and Eligible Obligations (including the proceeds thereof) deposited with the Defeasance Trustee pursuant to Section 15(d) in respect of the Securities shall be held in trust (which in the case of cash, shall be uninvested) and applied by the Defeasance Trustee, in accordance with the provisions of the Securities and this Agreement, to the payment, either directly or through any Paying Agent as the Defeasance Trustee may determine, to the holders of the Securities, of all sums due and to become due thereon in respect of principal, premium, if any, and any interest, but such money need not be segregated from other funds except to the extent required by law. Any money deposited with the Defeasance Trustee for the payment of the principal of, premium, if any, or any interest on any Security and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer upon an Order; and the holder of such Security shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof and all liability of the Defeasance Trustee with respect to such trust money shall thereupon cease. In the absence of an Order from the Issuer to return unclaimed funds to the Issuer, the Defeasance Trustee shall from time to time deliver all unclaimed funds to or as directed by applicable escheat authorities, as determined by the Defeasance Trustee in its sole discretion, in accordance with the customary practices and procedures of the Defeasance Trustee.

The Issuer shall pay and indemnify the Defeasance Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations or Eligible Obligations deposited pursuant to Section 15(d) or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the holders of the Outstanding Securities.

Anything in this Section 15 to the contrary notwithstanding, the Defeasance Trustee shall deliver or pay to the Issuer from time to time upon the request of the Issuer any money, U.S. Government Obligations or Eligible Obligations held by it as provided in Section 15(d) which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Defeasance Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

(f)Reinstatement. If the Defeasance Trustee is unable to apply any money in accordance with Section 15(b) or 15(c) by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer's obligations under this Agreement and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Section 15 until such time as the Defeasance Trustee is permitted to apply all such money in accordance with Section 15(b) or 15(c); provided, however, that if the Issuer makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the holders of such Securities to receive such payment from the money held by the Defeasance Trustee.

16.Headings. The section headings herein are for convenience only and shall not affect the construction hereof.

17.Counterparts. This Agreement may be executed in one or more counterparts, and by each party separately on a separate counterpart, and each such counterpart when executed and delivered shall be deemed to be an original. Such counterparts shall together constitute one and the same instrument.

18.Successors and Assigns. All covenants and agreements in this Agreement by the Issuer shall bind its respective successors and assigns, whether so expressed or not.

NY3667693.729

19.Separability Clause. In case any provision in this Agreement or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

20.Waiver of Jury Trial. EACH OF THE ISSUER AND THE FISCAL AGENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTION CONTEMPLATED HEREBY.

21.Force Majeure. In no event shall the Fiscal Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Fiscal Agent shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

[Form of reverse of Security]

1.This Security is one of a duly authorized issue of securities of the Issuer designated as its 4.10% Senior Bonds due 2042 (herein called the “Securities”), issued in aggregate principal amount of $250,000,000 and to be issued in accordance with a Fiscal Agency Agreement, dated as of August 27, 2012 (herein called the “Fiscal Agency Agreement”), between the Issuer and The Bank of New York Mellon Trust Company, N.A., as Fiscal Agent (herein called the “Fiscal Agent,” which term includes any successor fiscal agent under the Fiscal Agency Agreement), copies of which Fiscal Agency Agreement are on file and available for inspection at the corporate trust office of the Fiscal Agent which at the date hereof is at 2 N. LaSalle Street, Suite 1020, Chicago, Illinois 60602.

The Securities are unsecured direct, unconditional and general obligations of the Issuer and will rank equally with all other unsecured and unsubordinated indebtedness of the Issuer.

2.[If this Security is a Global Security, insert-This Security is issuable only in fully registered form, without coupons, in minimum denominations of U.S. $2,000 and integral multiples of $1,000 in excess of $2,000.] [If this Security is a Restricted Definitive Security, insert-This Security is issuable only in fully registered form, without coupons, in minimum denominations of U.S. $200,000 and integral multiples of $1,000 in excess of $200,000.]

3.The Issuer shall maintain in the Borough of Manhattan, The City of New York, an established place of business or agency where Securities may be surrendered for registration of transfer or exchange. The Issuer has initially appointed the Fiscal Agent acting through its corporate trust office in Chicago, and at its agent's office in the Borough of Manhattan, The City of New York, as its agent for such purpose and the Issuer has agreed to cause to be kept at such offices a register in which, subject to such reasonable regulations as it may prescribe, the Issuer will provide for the registration of Securities and of transfers of Securities. The Issuer reserves the right to vary or terminate the appointment of the Fiscal Agent as security registrar or of any Transfer Agent or to appoint additional or other registrars or Transfer Agents or to approve any change in the office through which any security registrar or any Transfer Agent acts, provided that there will at all times be a security registrar or agent thereof in the Borough of Manhattan, The City of New York. Registered holders of the Securities will receive notice of any such change.

The transfer of a Security is registrable on the aforementioned register upon surrender of such Security at the corporate trust office of the Fiscal Agent or the office of the agent of the Fiscal Agent or any Transfer Agent duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Fiscal Agent duly executed by, the registered holder thereof or such holder's attorney duly authorized in writing. Upon such surrender of this Security for registration of transfer, the Issuer shall execute, and the Fiscal Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities, dated the date of authentication thereof of any authorized denominations and of a like aggregate principal amount.

NY3667693.7A -8

At the option of the registered holder upon request confirmed in writing, Securities may be exchanged for Securities of any authorized denominations and of a like tenor, form and aggregate principal amount upon surrender of the Securities to be exchanged at the office of any Transfer Agent or at the corporate trust office of the Fiscal Agent or agent thereof. Whenever any Securities are so surrendered for exchange, the Issuer shall execute, and the Fiscal Agent shall authenticate and deliver, the Securities which the registered holder making the exchange is entitled to receive. Any registration of transfer or exchange will be effected upon the Transfer Agent or the Fiscal Agent, as the case may be, being satisfied with the documents of title and identity of the person making the request and subject to such reasonable regulations as the Issuer may from time to time agree with the Transfer Agent and the Fiscal Agent.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Issuer evidencing the same debt, and entitled to the same benefits, as the Securities surrendered upon such registration of transfer or exchange. No service charge shall be made for any registration of transfer or exchange, but the Issuer 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 Issuer, the Fiscal Agent and any agent of the Issuer or the Fiscal Agent 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 Issuer, the Fiscal Agent nor any such agent shall be affected by notice to the contrary.

[If this Security is a Regulation S Temporary Global Security, insert--This Regulation S Temporary Global Security is exchangeable in whole or in part for one or more Global Securities only (i) on or after the termination of the 40-day Distribution Compliance Period (as defined in Regulation S) and (ii) upon presentation of certificates required by Section 5(d) of the Fiscal Agency Agreement. Upon exchange of this Regulation S Temporary Global Security for one or more Global Securities, the Fiscal Agent shall cancel this Regulation S Temporary Global Security.]

4.(a)The Issuer shall pay to the Fiscal Agent at its Corporate Trust Office, on or prior to each Interest Payment Date and the maturity date of the Securities, in such amounts sufficient (with any amounts then held by the Fiscal Agent and available for the purpose) to pay the interest on, principal of and premium, if any, on the Securities due and payable on such Interest Payment Date or maturity date, as the case may be, in funds available on such date. The Fiscal Agent shall apply the amounts so paid to it to the payment of such interest and principal in accordance with the terms of the Securities. Any monies paid by the Issuer to the Fiscal Agent for the payment of the principal of, premium, if any, or interest on any Securities and remaining unclaimed at the end of two years after such principal, premium, if any, or interest shall have become due and payable (whether at maturity or otherwise) shall then be repaid to the Issuer upon its written request, and upon such repayment all liability of the Fiscal Agent with respect thereto shall cease, without, however, limiting in any way any obligation the Issuer may have to pay the principal of, premium, if any, and interest on this Security as the same shall become due.

(b)In any case where the due date for the payment of the principal of, premium, if any, or interest on any Security shall be at any place of payment on a day on which banking institutions are authorized or obligated by law to close, then payment of principal, premium, if any, or interest need not be made on such date at such place but may be made on the next succeeding day at such place which is not a day on which banking institutions are authorized or obligated by law to close, with the same force and effect as if made on the date for such payment, and no interest shall accrue for the period after such date.

NY3667693.7A -9

5.The Securities are subject to redemption upon not less than 30 or more than 60 days' notice to the registered holders of such Securities, at any time, as a whole or in part, at the election of the Issuer, at a redemption price equal to the greater of: (i) 100% of the Principal Amount of the Securities being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities being redeemed discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 25 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities to the Redemption Date.

The Securities are also subject to redemption upon not less than 30 or more than 60 days' notice to the registered holders of such Securities, at any time on or after March 15, 2042 (which is the date that is six months prior to the maturity date of the Securities), as a whole or in part, at the election of the Issuer, at a redemption price equal to 100% of the Principal Amount of the Securities being redeemed, plus accrued and unpaid interest on the Securities to the Redemption Date.

If fewer than all the Securities are to be redeemed, selection of Securities for redemption will be made by the Fiscal Agent in any manner the Fiscal Agent deems fair and appropriate; provided, however, that so long as the Securities are in the form of Global Securities, such selection will be made by the U.S. Depository in accordance with its applicable procedures.

Unless the Issuer defaults in payment of the redemption price, from and after the Redemption Date, the Securities or portions thereof called for redemption will cease to bear interest, and the holders thereof will have no right in respect of such Securities except the right to receive the redemption price thereof.

[If this Security is a Global Security, insert-In the event of redemption of this Security in part only, the Fiscal Agent will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.]

10.Section 8 of the Fiscal Agency Agreement, which requires the Issuer to provide registered holders of Securities or, in the case of clauses (a) and (b) thereof, designated prospective purchasers of Securities with certain information and an Officers' Certificate, is hereby incorporated mutatismutandis by reference herein.

11.Until the date that is one year from the date of original issuance of the Securities, the Issuer will not, and will not permit any of its “affiliates” (as defined under Rule 144 under the Act or any successor provision thereto) to, resell any Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

Every new Security issued pursuant to this Paragraph 12 in lieu of any destroyed, lost or stolen Security, shall constitute an original additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone.

Any new Security delivered pursuant to this Paragraph 12 shall be so dated that neither gain nor loss in interest shall result from such exchange.

The provisions of this Paragraph 12 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.
