        one or more series, as the case may be, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. If Securities of a series are issuable as
        Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by
        the record of Holders of Securities of such series voting in favor thereof, whether in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of
        Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and,
        where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument
        or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject
        to Section 612) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner
        provided in Section 1506.

      

      

      
        8

        
          


      

      (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other
        officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his
        individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved
        in any other reasonable manner which the Trustee deems sufficient.

      

      

      (c) The ownership of Registered Securities shall be proved by the Security Register or by a certificate of the Security Registrar.

      

      

      (d) The ownership of Bearer Securities may be proved by the production of such Bearer Securities or by a certificate executed, as depository, by any trust company, bank, banker or other depository,
        wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depository, or exhibited to it, the Bearer Securities therein described; or
        such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any
        Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer
        Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership of Bearer Securities may also be proved in any other manner which the Trustee deems sufficient.

      

      

      (e) If the Company shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, in or
        pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so.
        Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in
        connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but
        only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to
        such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders
        on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

      

      

      (f) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every
        Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, any Security Registrar, any Paying Agent, any Authenticating Agent or
        the Company in reliance thereon, whether or not notation of such action is made upon such Security.

        of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to
        Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or
        direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
        Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
        (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite
        principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the
        proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

      

      

      (h) With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the
        Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in
        the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to
        have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
        later than the 180th day after the applicable record date. Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal
        amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

      

      

      Section 105 Notices, Etc., To The Trustee And Company.

      

      

      Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to or filed
        with,

      

      

      (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office,
        Attention: Corporate Trustee Administration, or

      

      

      (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first class postage prepaid,
        to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company.

      

      

      Section 106 Notice To Holders; Waiver.

      

      

      Where this Indenture provides for notice of any event to Holders of Registered Securities by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly
        provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed
        for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of
        such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed
        to have been received by such Holder, whether or not such Holder actually receives such notice.

      

      

      If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders
        of Registered Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder.

      

      

      
        10

        
          


      

      Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 301, where this Indenture provides for notice to Holders of Bearer Securities
        of any event, such notice shall be sufficiently given if published in an Authorized Newspaper in The City of New York and in such other city or cities as may be specified in such Securities, and if the Securities of such series are listed on any
        stock exchange outside the United States, in any place at which such Securities are listed on a securities exchange to the extent that such securities exchange so requires, on a Business Day, such publication to be not later than the latest date,
        and not earlier than the earliest date, prescribed for the giving of such notice. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once, on the date of the first such publication.

      

      

      If by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of
        Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither the failure to
        give notice by publication to any particular Holder of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the sufficiency
        of any notice to Holders of Registered Securities given as provided herein.

      

      

      Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an
        official language of the country of publication.

      

      

      Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall
        be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

      

      

      Notwithstanding any of the foregoing, notices with respect to any global Security shall be sufficient if given in accordance with the applicable procedures of the relevant Depository.

      

      

      Section 107 Effect Of Headings And Table Of Contents.

      

      

      The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

      

      

      Section 108 Successors And Assigns.

      

      

      All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

      

      

      Section 109 Separability Clause.

      

      

      In case any provision in this Indenture or in any Security or coupon 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.

      

      

      Section 110 Benefits Of Indenture.

      

      

      Nothing in this Indenture or in the Securities or coupons appertaining thereto, express or implied, shall give to any Person, other than the parties hereto, any Security Registrar, any Paying
        Agent, any Authenticating Agent and their successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture.

      Section 111 No Personal Liability.

      

      

      No recourse under or upon any obligation, covenant or agreement contained in this Indenture, in any Security or coupon appertaining thereto, or because of any indebtedness evidenced thereby, shall
        be had against any promoter, as such, or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or
        constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the Holders thereof and as part of
        the consideration for the issue of the Securities.

      

      

      Section 112 Governing Law; Waiver of Trial by Jury.

      

      

      This Indenture and the Securities and coupons shall be governed by and construed in accordance with the laws of the State of New York. This Indenture is subject to the provisions of the TIA that
        are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions and any provisions of this Indenture that are not permitted by the provisions of the TIA shall be deemed to be deleted or modified to the
        extent such provisions are required to be deleted or modified for the Indenture to be qualified under the TIA. Each of the Company and the Trustee 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 Indenture or the transactions contemplated hereby.

      

      

      Section 113 Legal Holidays.

        to convert or exchange a Security at a particular conversion or exchange price shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security or coupon other than a provision in the
        Securities of any series which specifically states that such provision shall apply in lieu hereof), payment of interest or any Additional Amounts or principal (and premium or Make-Whole Amount, if any) need not be made at such Place of Payment on
        such date, conversion or exchange need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date,
        Redemption Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or Maturity or on such last day for conversion or exchange, provided that so long as such payment is made on the next succeeding Business Day, no interest shall
        accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity or on such last day for conversion or exchange, as the case may be, to
        such Business Day.

        established in or pursuant to one or more indentures supplemental hereto or by or pursuant to authority granted by one or more Board Resolutions, shall have such appropriate insertions, omissions, substitutions and other variations as are required
        or permitted by this Indenture or any indenture supplemental hereto, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements placed thereon as the Company may deem appropriate and as are

        any Depository therefor, or to conform to usage. If temporary Securities of any series are issued as permitted by Section 304, the form thereof also shall be established as provided in the preceding sentence. If the forms of Securities and coupons,
        if any, of any series are established by, or by action taken pursuant to, a Board Resolution, a copy of the Board Resolution together with an appropriate record of any such action taken pursuant thereto, including a copy of the approved form of
        Securities or coupons, if any, shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 303 for the authentication and
        delivery of such Securities.

      

      

      
        12

        
          


      

      Unless otherwise specified as contemplated by Section 301, Bearer Securities shall have interest coupons attached.

      

      

      The definitive Securities and coupons, if any, shall be printed, lithographed or engraved or produced by any combination of these methods on a steel engraved border or steel engraved borders or may
        be produced in any other manner, all as determined by the officers of the Company executing such Securities or coupons, as evidenced by their execution of such Securities or coupons.

      

      

      Section 202 Form Of Trustee’s Certificate Of Authentication.

      

      

      Subject to Section 611, the Trustee’s certificate of authentication shall be in substantially the following form:

      

      

      This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

      

      

      	 	 	
              , as Trustee

            


      

      

      	 	
              By:

            	 	 
	 	 	
              Authorized Signatory

            	 


      

      

      Section 203 Securities Issuable In Global Form.

      

      

      If Securities of or within a series are issuable in global form, as specified as contemplated by Section 301, then, notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
        such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such series from time to time endorsed thereon
        and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or
        decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon written instruction given by such Person or Persons as shall be specified therein or in the Company Order to be delivered to
        the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon written instructions
        given by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 303 or Section 304 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or
        delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 102 and need not be accompanied by an Opinion of Counsel.

      

      

      The provisions of the last sentence of Section 303 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Company and the Company
        delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities
        represented thereby, together with the written statement contemplated by the last sentence of Section 303.

      

      

      Notwithstanding the provisions of Section 307, unless otherwise specified as contemplated by Section 301, payment of principal of and any premium or Make-Whole Amount and interest on any Security
        in permanent global form shall be made to the Person or Persons specified therein.

      

      

      Notwithstanding the provisions of Section 308 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company and the Trustee shall treat as the Holder of
        such principal amount of Outstanding Securities represented by a permanent global Security (i) in the case of a permanent global Security in registered form, the Holder of such permanent global Security in registered form, or (ii) in the case of a
        permanent global Security in bearer form, Euroclear or Clearstream.

        and the terms and conditions upon which such conversion or exchange shall be effected (including, without limitation, the initial conversion price or rate, the conversion or exchange period, any adjustment of the applicable conversion or exchange
        price or rate and any requirements relative to the reservation of such shares for purposes of conversion or exchange);

      

      

      (24) if convertible or exchangeable, any applicable limitations on the ownership or transferability of the securities or property into which such Securities are convertible or exchangeable;

      

      

      (25) if the principal amount payable at the Stated Maturity of any Securities of the series will not be determinable as of any one or more dates prior to the Stated Maturity, the amount which shall
        be deemed to be the principal amount of such Securities as of any such date for any purpose thereunder or hereunder, including the principal amount thereof which shall be due and payable upon any Maturity other than the Stated Maturity or which
        shall be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in any such case, the manner in which such amount deemed to be the principal amount shall be determined); and

      

      

      (26) any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture except as permitted by Section 901(5)).

      

      

      All Securities of any one series and the coupons appertaining to any Bearer Securities of such series, if any, shall be substantially identical except, in the case of Registered or Bearer
        Securities issued in global form, as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution or in any indenture supplemental hereto. All Securities of any one series need not be issued at the same time and,
        unless otherwise provided, a series may be reopened, without the consent of the Holders, for issuances of additional Securities of such series.

      

      

      
        16

        
          


      

      If any of the terms of the Securities of any series are established by action taken pursuant to, or by authority granted pursuant to, one or more Board Resolutions, a copy of an appropriate record
        of such action(s) shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order for authentication and delivery of such Securities.

      

      

      Section 302 Denominations.

      

      

      The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by Section 301. With respect to Securities of any series denominated in Dollars, in the
        absence of any such provisions with respect to the Securities of any series, the Registered Securities of such series, other than Registered Securities issued in global form (which may be of any denomination), shall be issuable in denominations of
        $2,000 and integral multiples of $1,000 in excess thereof and the Bearer Securities of such series, other than Bearer Securities issued in global form (which may be of any denomination), shall be issuable in denominations of $5,000 and any integral
        multiple thereof.

      

      

      Section 303 Execution, Authentication, Delivery And Dating.

      

      

      The Securities and any coupons appertaining thereto shall be executed on behalf of the Company by a Chief Executive Officer, President or Vice President. The signature of any of these officers on
        the Securities and coupons may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities.

      

      

      Securities or coupons appertaining thereto bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding
        that such individuals or any of them have ceased 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 or coupons.

      

      

      At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with any coupon appertaining thereto, executed by
        the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities; provided,
        however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the United States; and provided further that, unless otherwise specified with respect to any series of Securities
        pursuant to Section 301 a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate to Euroclear or Clearstream, as the case may be, in
        the form set forth in Exhibit A-1 to this Indenture or such other certificate as may be specified with respect to any series of Securities pursuant to Section 301, dated no earlier than 15 days prior to the earlier of the date on which such Bearer
        Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. Except as permitted by Section 306, the Trustee shall
        not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and canceled.

      

      

      If all of the Securities are not to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures
        acceptable to the Trustee for the issuance of such Securities and determining the terms of particular Securities of such series, such as interest rate or formula, maturity date, date of issuance and date from which interest shall accrue. In
        authenticating Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 612 and TIA Section 315(a) through 315(d)) shall be
        fully protected in conclusively relying upon:

      

      

      (i) an Opinion of Counsel complying with Section 102 and stating that:

      

      

      (a) the form or forms of such Securities and any coupons have been, or will have been upon compliance with such procedures as may be specified therein, established in conformity with the provisions
        of this Indenture;

      

      

      
        17

        
          


      

      (b) the terms of such Securities and any coupons have been, or will have been upon compliance with such procedures as may be specified therein, established in conformity with the provisions of this
        Indenture; and

      

      

      (c) such Securities, together with any coupons appertaining thereto, when completed pursuant to such procedures as may be specified therein, and executed and delivered by the Company to the Trustee
        for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will
        constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the
        enforcement of creditors’ rights generally and to general equitable principles and to such other matters as may be specified therein; and

      

      

      (ii) an Officers’ Certificate complying with Section 102 and stating that all conditions precedent provided for in this Indenture relating to the issuance of such Securities have been, or will have
        been upon compliance with such procedures as may be specified therein, complied with and that, to the best of the knowledge of the signers of such certificate, no Event of Default with respect to such Securities shall have occurred and be
        continuing.

      

      

      Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver a Company
        Order, an Opinion of Counsel or an Officers’ Certificate otherwise required pursuant to the preceding paragraph at the time of issuance of each Security of such series, but such order, opinion and certificate, with appropriate modifications to
        cover such future issuances, shall be delivered at or before the time of issuance of the first Security of such series.

      

      

      The Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties, obligations or
        immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

      

      

      Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated by Section 301.

      

      

      No Security or coupon appertaining thereto shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security or the Security to
        which such coupon appertains a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive
        evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered
        hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 102 and need not be
        accompanied by an Opinion of Counsel) stating that such Security has never been issued or sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never
        be entitled to the benefits of this Indenture.

      

      

      Section 304 Temporary Securities.

      

      

      (a) Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall
        authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are
        issued, in registered form, or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities
        may determine, as conclusively evidenced by their execution of such Securities. In the case of Securities of any series, such temporary Securities may be in global form.

      

      

      
        18

        
          


      

      Except in the case of temporary Securities in global form (which shall be exchanged in accordance with Section 304(b) or as otherwise provided in or pursuant to a Board Resolution), if temporary
        Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall
        be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for
        cancellation of any one or more temporary Securities of any series (accompanied by any non-matured coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount
        of definitive Securities of the same series of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that a definitive Bearer
        Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 303. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same
        benefits under this Indenture as definitive Securities of such series.

      

      

      (b) Unless otherwise provided as contemplated in Section 301, this Section 304(b) shall govern the exchange of temporary Securities issued in global form other than through the facilities of DTC.
        If any such temporary Security is issued in global form, then such temporary global Security shall, unless otherwise provided therein, be delivered to the London office of a depository or common depository (the “Common Depository”), for the benefit
        of Euroclear and Clearstream.

      

      

      Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security (the “Exchange Date”), the Company
        shall deliver to the Trustee definitive Securities, in an aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or after the Exchange Date, such temporary global Security shall be
        surrendered by the Common Depository to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in
        exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of or within the same series of authorized denominations and of like tenor as the portion of such temporary global Security to
        be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as
        specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided, however, that, unless otherwise specified in such temporary global Security, upon such presentation
        by the Common Depository, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euroclear as to the portion of such temporary global Security, if any, held for its account then to
        be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global Security, if any, held for its account then to be exchanged, each in the form set forth in Exhibit A-2
        to this Indenture or in such other form as may be established pursuant to Section 301; and provided further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security only in compliance with the
        requirements of Section 303.

      

      

      Unless otherwise specified in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive
        Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear or Clearstream, as the case
        may be, a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 301), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate shall be
        available from the offices of Euroclear or Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be
        made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like unless such Person takes delivery of such
        definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall be delivered only outside the United States.

      

      

      
        19

        
          


      

      Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the
        same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series
        occurring prior to the applicable Exchange Date shall be payable to Euroclear or Clearstream on such Interest Payment Date upon delivery by Euroclear or Clearstream to the Trustee of a certificate or certificates in the form set forth in Exhibit
        A-2 to this Indenture (or in such other forms as may be established pursuant to Section 301), for credit without further interest on or after such Interest Payment Date to the respective accounts of Persons who are the beneficial owners of such
        temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange
        Date in the form set forth as Exhibit A-1 to this Indenture (or in such other forms as may be established pursuant to Section 301). Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall
        satisfy the certification requirements of the preceding two paragraphs of this Section 304(b) and of the third paragraph of Section 303 of this Indenture and the interests of the Persons who are the beneficial owners of the temporary global
        Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange Date or the date of certification if such date occurs after the Exchange Date, without
        further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal or interest owing with respect to a beneficial interest in a temporary global Security will be made unless and until such
        interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear or Clearstream and not paid as herein provided shall be returned to the Trustee prior to the
        expiration of two years after such Interest Payment Date in order to be repaid to the Company.

      

      

      Section 305 Registration, Registration Of Transfer And Exchange.

      

      

      The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register for each series of Securities (the
        registers maintained in such office or in any such office or agency of the Company in a Place of Payment being herein sometimes referred to collectively as the “Security Register”) in which, subject to such reasonable regulations as it or the
        Security Registrar may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Security Register shall be in written form or any other form capable of being converted into
        written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed “Security Registrar” for the purpose of registering Registered Securities and transfers of Registered Securities on such Security
        Register as herein provided. In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at all reasonable times and to require that a copy of the Security Register in written form be
        delivered to it from time to time as reasonably requested. Subject to the provisions of this Section 305, upon surrender for registration of transfer of any Registered Security of any series at any office or agency of the Company in a Place of
        Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized denominations
        and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical terms and provisions.

      

      

      Subject to the provisions of this Section 305, at the option of the Holder, Registered Securities of any series (not in global form) may be exchanged for other Registered Securities of the same
        series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical terms and provisions, upon surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any such
        Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with
        respect to any series of Securities as contemplated by Section 301, Bearer Securities may not be issued in exchange for Registered Securities.

      

      

      
        20

        
          


      

      If (but only if) permitted as contemplated by Section 301, at the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any
        authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured coupons in default thereto appertaining.
        If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds
        acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there is furnished to them such security or
        indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such
        Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an
        office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like
        tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of
        business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be,
        and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will
        be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the
        Securities which the holder making the exchange is entitled to receive.

      

      

      Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph. If the
        Depository for any permanent global Security is DTC, then, unless the terms of such global Security expressly permit such global Security to be exchanged in whole or in part for definitive Securities, a global Security may be transferred, in whole
        but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies the Company that
        it is unwilling or unable to continue as depository for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency registered under the Exchange Act if so required by applicable law or regulation, the Company
        shall appoint a successor depository with respect to such global Security or Securities. If (x) a successor depository for such global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or
        becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable series of Securities represented by such
        global Security or Securities advise DTC to cease acting as depository for such global Security or Securities or (z) the Company, in its sole discretion and subject to the procedures of DTC, determines at any time that all Outstanding Securities
        (but not less than all) of any series issued or issuable in the form of one or more global Securities shall no longer be represented by such global Security or Securities (provided, however, the Company may not make such determination during the
        40-day restricted period provided by Regulation S under the Securities Act or during any other similar period during which the Securities must be held in global form as may be required by the Securities Act), then the Company shall execute, and the
        Trustee shall authenticate and deliver definitive Securities of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such global Security or Securities. If any beneficial owner of
        an interest in a permanent global Security is otherwise entitled to exchange such an interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section
        301 and provided that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company
        shall execute, and the Trustee shall authenticate and deliver definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security. On or after the earliest date on
        which such interests may be so exchanged, such permanent global Security shall be surrendered for exchange by DTC or such other depository as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for
        such purpose; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which
        exchange is requested may be among those selected for redemption; and provided further that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United
        States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business
        at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted
        Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for
        payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

      

      

      
        21

        
          


      

      All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under
        this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

      

      

      Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company, the Trustee or the Security Registrar) be duly
        endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

      

      

      No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge
        that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, Section 906, Section 1107 or Section 1305 not involving any transfer.

      

      

      The Company or the Trustee, as applicable, shall not be required (i) to issue, register the transfer of or exchange any Security if such Security may be among those selected for redemption during a
        period beginning at the opening of business 15 days before selection of the Securities to be redeemed under Section 1103 and ending at the close of business on (A) if such Securities are issuable only as Registered Securities, the day of the
        mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if such Securities are also issuable as Registered Securities and
        there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except, in the case of any Registered Security to be
        redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that
        such Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue or to register the transfer or exchange of any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any,
        of such Security not to be so repaid.

      

      

      Section 306 Mutilated, Destroyed, Lost And Stolen Securities.

      

      

      If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee or the Company, together with such security or indemnity as may be required by the
        Company or the Trustee to save each of them or any agent of either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and principal amount, containing
        identical terms and provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.

      

      

      If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon, and (ii) such security or indemnity as
        may be required by them to save each of them and any agent of either of them harmless, then, in the absence of actual notice to the Company or the Trustee that such Security or coupon has been acquired by a bona fide purchaser, the Company shall
        execute and upon its written request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant
        coupons not destroyed, lost or stolen), a new Security of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any,
        appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains.

      

      

      
        22

        
          


      

      Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company
        in its discretion may, instead of issuing a new Security, with coupons corresponding to coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains, pay such
        Security or coupon; provided, however, that payment of principal of (and premium or Make-Whole Amount, if any), any interest on and any Additional Amounts with respect to Bearer Securities shall, except as otherwise provided in Section 1002, be
        payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons
        appertaining thereto.

      

      

      Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
        thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

      

      

      Every new Security of any series with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed,
        lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any
        time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series and their coupons, if any, duly issued hereunder.

      

      

      The provisions of this Section 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 or coupons.

      

      

      Section 307 Payment Of Interest; Interest Rights Preserved.

      

      

      Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, interest on any Registered Security that is payable, and is punctually paid or
        duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or
        agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest on any Registered Security may at the Company’s option be paid by (i) mailing a check for such interest, payable to or
        upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the payee located inside the United States.

      

      

      Unless otherwise provided as contemplated by Section 301 with respect to the Securities of any series, payment of interest may be made, in the case of a Bearer Security, by transfer to an account
        maintained by the payee with a bank located outside the United States.

      

      

      Unless otherwise provided as contemplated by Section 301, every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to DTC, Euroclear
        and/or Clearstream, as the case may be, with respect to that portion of such permanent global Security held for its account by DTC, Euroclear or Clearstream, as the case may be, for the purpose of permitting such party to credit the interest
        received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof.

      

      

      In case a Bearer Security of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such
        series) on any Regular Record Date and before the opening of business (at such office or agency) on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date and
        interest will not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this
        Indenture.

      

      

      
        23

        
          


      

      Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, any interest on any Registered Security of any series that is payable, but is
        not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such
        Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

      

      

      (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are
        registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to
        be paid on each Registered Security of such series and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount
        of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) equal to
        the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust
        for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than
        10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at
        the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Registered Securities of such series at his address
        as it appears in the Security Register not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest
        shall be paid to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the
        following clause (2). In case a Bearer Security of any series is surrendered at the office or agency in a Place of Payment for such series in exchange for a Registered Security of such series after the close of business at such office or agency on
        any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such proposed date of
        payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with
        the provisions of this Indenture.

      

      

      (2) The Company may make payment of any Defaulted Interest on the Registered Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on
        which such Securities may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed
        practicable by the Trustee.

      

      

      Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other
        Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

      

      

      Subject to the provisions of Section 1402 and except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, in the case of any Security
        which is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Security, the principal of (or premium, if any, on) which shall become due and payable, whether at a Stated
        Maturity or by declaration of acceleration, call for redemption, or otherwise, prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such
        conversion or exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on such Regular
        Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted or exchanged, interest whose Stated Maturity is after the date of conversion or exchange of such Security
        shall not be payable.

      Section 308 Persons Deemed Owners.

      

      

      Prior to due presentment of a Registered 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 such
        Registered Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium or Make-Whole Amount, if any), and (subject to Section 305 and Section 307) interest on and Additional Amounts with
        respect to, such Registered Security and for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the
        contrary.

      

      

      Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company, the Trustee and any agent of the Company or the Trustee may treat the Holder of any Bearer
        Security and the Holder of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Security or coupon be overdue, and
        neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

      

      

      None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of
        beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

      

      

      Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any
        written certification, proxy or other authorization furnished by any depository, as a Holder, with respect to such global Security or impair, as between such depository and owners of beneficial interests in such global Security, the operation of
        customary practices governing the exercise of the rights of such depository (or its nominee) as Holder of such global Security.

      

      

      Section 309 Cancellation.

      

      

      All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against any sinking fund payment shall, if
        surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall be promptly canceled by it. The Company may
        at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to
        the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If the Company shall so acquire any of the
        Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be
        authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. Canceled Securities and coupons held by the Trustee shall be destroyed by the Trustee and, if required
        in writing by the Company, the Trustee shall deliver a certificate of such destruction to the Company, unless by a Company Order the Company directs their return to it.

      

      

      Section 310 Computation Of Interest.

      

      

      Except as otherwise specified as contemplated by Section 301 with respect to Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year
        consisting of twelve 30-day months.

      Section 311 Cusip Numbers.

      

      

      The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption or other related material as a
        convenience to Holders; provided that any such notice or other related material may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption or other
        related material and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.

        theretofore delivered to the Trustee for cancellation, for principal (and premium or Make-Whole Amount, if any) and interest, and any Additional Amounts with respect thereto, to the date of such deposit (in the case of Securities which have become
        due and payable) or the Stated Maturity or Redemption Date, as the case may be;

        principal (and premium or Make-Whole Amount, if any), and any interest and Additional Amounts for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated from other funds except to the

        all Securities of any series will become immediately due and payable without any action on the part of the Trustee or any Holder.

      

      

      
        28

        
          


      

      At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the
        Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its
        consequences if:

      

      

      (1) the Company has paid or deposited with the Trustee a sum sufficient to pay in the currency, currency unit or composite currency in which the Securities of such series are payable (except as
        otherwise specified pursuant to Section 301 for the Securities of such series):

      

      

      (A) all overdue installments of interest on and any Additional Amounts payable in respect of all Outstanding Securities of that series and any related coupons;

      

      

      (B) the principal of (and premium or Make-Whole Amount, if any, on) any Outstanding Securities of that series which have become due otherwise than by such declaration of
        acceleration and interest thereon at the rate or rates borne by or provided for in such Securities;

      

      

      (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest and any Additional Amounts at the rate or rates borne by or provided for
        in such Securities; and

      

      

      (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

      

      

      (2) all Events of Default with respect to Securities of that series, other than the nonpayment of the principal of (or premium or Make-Whole Amount, if any) or interest on Securities of that series
        which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

      

      

      No such rescission shall affect any subsequent default or impair any right consequent thereon.

      

      

      Section 503 Collection Of Indebtedness And Suits For Enforcement By Trustee.

      

      

      The Company covenants that if:

      

      

      (1) default is made in the payment of any installment of interest or Additional Amounts, if any, on any Security of any series and any related coupon when such interest or Additional Amount becomes
        due and payable and such default continues for a period of 30 days, or

      

      

      (2) default is made in the payment of the principal of (or premium or Make-Whole Amount, if any, on) any Security of any series at its Maturity, then the Company will, upon demand of the Trustee,
        pay to the Trustee, for the benefit of the Holders of such Securities of such series and coupons, the whole amount then due and payable on such Securities and coupons for principal (and premium or Make-Whole Amount, if any) and interest and
        Additional Amounts, with interest upon any overdue principal (and premium or Make-Whole Amount, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest or Additional Amounts,
        if any, at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
        disbursements and advances of the Trustee, its agents and counsel.

      

      

      If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the
        sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities of such series and collect the moneys adjudged or decreed to be payable in
        the manner provided by law out of the property of the Company or any other obligor upon such Securities of such series, wherever situated.

      

      

      
        29

        
          


      

      If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders
        of Securities of such series and any related coupons by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this
        Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

      

      

      Section 504 Trustee May File Proofs Of Claim.

      

      

      In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any
        other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities of any series shall then be due and payable as therein expressed or
        by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium or Make-Whole Amount, if any, or interest) shall be entitled and empowered, by intervention
        in such proceeding or otherwise to take any and all actions authorized under the TIA in order to have any claims of the Holders and the Trustee allowed in any such proceeding and:

      

      

      (i) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of principal (and premium or Make-Whole
        Amount, if any) and interest and Additional Amounts, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim
        for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

      

      

      (ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

      

      

      and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Holder of Securities of such series and coupons to
        make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and
        advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 606.

      

      

      Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or coupon any plan of reorganization,
        arrangement, adjustment or composition affecting the Securities or coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or coupon in any such proceeding; provided,
        however, that the Trustee may, only on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee.

      

      

      Section 505 Trustee May Enforce Claims Without Possession Of Securities Or Coupons.

      

      

      All rights of action and claims under this Indenture or any of the Securities or coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or coupons or
        the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the
        reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities and coupons in respect of which such judgment has been recovered.

      Section 506 Application Of Money Collected.

      

      

      Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
        account of principal (or premium or Make-Whole Amount, if any) or interest and any Additional Amounts, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and
        upon surrender thereof if fully paid:

      

      

      FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 606,

      

      

      SECOND: To the payment of the amounts then due and unpaid upon the Securities and coupons for principal (and premium or Make-Whole Amount, if any) and interest and any Additional Amounts payable,
        in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Securities and coupons for principal (and premium or
        Make-Whole Amount, if any), interest and Additional Amounts, respectively, and

      

      

      THIRD: To the payment of the remainder, if any, to the Company.

      

      

      Section 507 Limitation On Suits.

      

      

      No Holder of any Security of any series or any related coupon shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a
        receiver or trustee, or for any other remedy hereunder, unless:

      

      

      (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

      

      

      (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of
        such Event of Default in its own name as Trustee hereunder;

      

      

      (3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request;

      

      

      (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

      

      

      (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding
        Securities of that series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights
        of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all
        such Holders.

      

      

      Section 508 Unconditional Right Of Holders To Receive Principal, Premium Or Make-Whole Amount, If Any, Interest And Additional Amounts.

      

      

      Notwithstanding any other provision in this Indenture, the Holder of any Security or coupon shall have the right which is absolute and unconditional to receive payment of the principal of (and
        premium or Make-Whole Amount, if any) and (subject to Section 305 and Section 307) interest on, and any Additional Amounts in respect of, such Security or payment of such coupon on the respective due dates expressed in such Security or coupon (or,
        in the case of redemption, on the Redemption Date), to convert or exchange such Securities in accordance with Article Sixteen and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent
        of such Holder.

      

      

      
        31

        
          


      

      Section 509 Restoration Of Rights And Remedies.

      

      

      If the Trustee or any Holder of a Security or coupon has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any
        reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, the Trustee and the Holders of Securities and coupons shall, subject to any determination in such proceeding, be restored severally
        and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

      

      

      Section 510 Rights And Remedies Cumulative.

      

      

      Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph of Section 306, no right or remedy herein
        conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every
        other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
        appropriate right or remedy.

      

      

      Section 511 Delay Or Omission Not Waiver.

      

      

      No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute
        a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee
        or by the Holders of Securities or coupons, as the case may be.

      

      

      Section 512 Control By Holders Of Securities.

      

      

      The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any
        proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series, provided that

      

      

      (1) such direction shall not be in conflict with any rule of law or with this Indenture,

      

      

      (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

      

      

      (3) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities of such series not joining therein (but the Trustee shall
        have no obligation as to the determination of such undue prejudice).

      

      

      Section 513 Waiver Of Past Defaults.

      

      

      The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series and any related
        coupons consent to the waiver of any past default hereunder with respect to such series and its consequences, except a default

      

      

      (1) in the payment of the principal of (or premium or Make-Whole Amount, if any) or interest including Additional Amounts payable in respect of any Security of such series or any related coupons,
        or

      

      

      (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

      

      

      
        32

        
          


      

      Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall
        extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

      

      

      Section 514 Waiver Of Stay, Usury Or Extension Laws.

      

      

      The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
        usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all
        benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been
        enacted.

      

      

      Section 515 Undertaking For Costs.

      

      

      All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
        enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that
        such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the
        provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities, or to any suit
        instituted by any Holder for the enforcement of the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on or Additional Amounts payable with respect to any Security on or after the respective Stated Maturities
        expressed in such Security (or in the case of redemption, on or after the Redemption Date) or to enforce the right to convert or exchange any Security in accordance with Article Sixteen.

        notice of such default hereunder actually known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium or
        Make-Whole Amount, if any) or interest on or any Additional Amounts with respect to any Security of such series, or in the payment of any sinking fund installment with respect to the Securities of such series, the Trustee shall be protected in
        withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Securities and coupons of such series; and provided further that in
        the case of any default or breach of the character specified in Section 501(4) with respect to the Securities and coupons of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose
        of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Securities of such series.

      

      

      Section 602 Certain Duties, Responsibilities And Rights Of Trustee.

      

      

      (a) The Trustee’s duties and responsibilities under this Indenture shall be governed by the Trust Indenture Act.

      

      

      (b) Subject to the provisions of TIA Section 315(a) through 315(d):

      

      

      
        33

        
          


      

      (1) except during the continuance of an Event of Default, the Trustee shall perform only such duties as are expressly undertaken by it to perform under this Indenture and no implied covenants or
        obligations shall be read into this Indenture against the Trustee;

      

      

      (2) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
        direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

      

      

      (3) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order (other than delivery of any Security, together with any coupons
        appertaining thereto, to the Trustee for authentication and delivery pursuant to Section 303 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently evidenced by a Board
        Resolution;

      

      

      (4) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the
        Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate;

      

      

      (5) the Trustee may consult with counsel and as a condition to the taking, suffering or omission of any action hereunder may demand an Opinion of Counsel, and the advice of such counsel or any
        Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

      

      

      (6) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of Securities of any series or
        any related coupons pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request
        or direction;

      

      

      (7) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
        consent, order, bond, debenture, note, coupon or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make
        such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney;

      

      

      (8) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, custodians or nominees and the Trustee shall

      (9) if the Trustee is acting as Paying Agent or Transfer Agent and Registrar hereunder, the rights, indemnities and protections afforded to the Trustee pursuant to this Article VI shall also be
        afforded to such Paying Agent or Transfer Agent and Registrar;

      

      

      (10) the Trustee shall not be deemed to have knowledge of any Event of Default unless the Trustee shall have received written notice, or a Responsible Officer charged with the administration of
        this Indenture shall have actual knowledge of such Event of Default;

      

      

      (11) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers
        conferred upon it by this Indenture. The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers,
        if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not reasonably assured to it;

      

      

      
        34

        
          


      

      (12) the Trustee shall not be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised
        of the likelihood of such loss or damage and regardless of the form of action; and

      

      

      (13) the Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture 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 or hardware) services.

      

      

      Section 603 Not Responsible For Recitals Or Issuance Of Securities.

      

      

      The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, and in any coupons shall be taken as the statements of the Company, and neither the Trustee
        nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities or coupons, except that the Trustee represents that it is
        duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities
        or the proceeds thereof.

      

      

      Section 604 May Hold Securities.

      

      

      The Trustee, any Paying Agent, Security Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and
        coupons and, subject to Section 613 and TIA Section 310(b) and Section 311, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such other agent.

      Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on, or investment of,
        any money received by it hereunder except as otherwise agreed in writing with the Company.

      

      

      Section 606 Compensation And Reimbursement.

      

      

      The Company agrees:

      

      

      (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder, including extraordinary services rendered in connection with or during the
        continuation of a default hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

      

      

      (2) to reimburse each of the Trustee and any predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by it in accordance with any provision of
        this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except to the extent any such expense, disbursement or advance may be attributable to its gross negligence or bad faith; and

      

      

      (3) to indemnify each of the Trustee and any predecessor Trustee and each of their respective directors, officers, agents and employees for, and to hold each of them harmless against, any loss,
        liability or expense, arising out of or in connection with the acceptance or administration of the trust or trusts or the performance of its duties hereunder, including the costs and expenses of defending itself against any claim or liability in
        connection with the exercise or performance of any of its powers or duties hereunder except to the extent any such loss, liability or expense may be attributable to its own gross negligence or bad faith.

      

      

      
        35

        
          


      

      As security for the performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the
        Trustee as such, except funds held in trust for the payment of principal of (or premium or Make-Whole Amount, if any) or interest on particular Securities or any coupons.

      

      

      Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default described in Section
        501(6) and (7), such expenses (including the fees and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law.

      

      

      The provisions of this Section shall survive the termination of this Indenture or the resignation or removal of the Trustee.

      

      

      Section 607 Corporate Trustee Required; Eligibility.

      

      

      There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000. If such
        Trustee or Person publishes reports of condition at least annually, pursuant to law or the requirements of Federal, State, Territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined
        capital and surplus of such Trustee or Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the
        provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

      

      

      Section 608 Resignation And Removal; Appointment Of Successor.

      

      

      (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee
        in accordance with the applicable requirements of Section 609.

      

      

      (b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If an instrument of acceptance by a successor Trustee
        shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

      

      

      (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities of such
        series delivered to the Trustee and to the Company.

      

      

      (d) If at any time:

      

      

      (1) the Trustee shall fail to comply with the provisions of Section 613 or TIA Section 310(b) after written request therefor by the Company or by any Holder of a Security who has been a bona fide
        Holder of a Security for at least six months, or

      

      

      (2) the Trustee shall cease to be eligible under Section 607 and shall fail to resign after written request therefor by the Company or by any Holder of a Security who has been a bona fide Holder of
        a Security for at least six months, or

      

      

      (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take
        charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company by or pursuant to a Board Resolution may remove the Trustee and appoint a
        successor Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated,
        petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

      

      

      
        36

        
          


      

      (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause with respect to the Securities of one or more series,
        the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to
        the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the requirements of Section 609.

      

      

      If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of
        the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the
        successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the
        Company or the Holders of Securities and accepted appointment in the manner hereinafter provided, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others
        similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to Securities of such series.

      

      

      (f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the
        Securities of any series to the Holders of Securities of such series in the manner provided for notices to the Holders of Securities in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such
        series and the address of its Corporate Trust Office.

      

      

      Section 609 Acceptance Of Appointment By Successor.

      

      

      (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee shall execute, acknowledge and deliver to the Company and to the
        retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all
        the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor
        Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any,
        provided for in Section 606.

      

      

      (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with
        respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as
        shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of
        such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the
        retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as
        shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
        trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the
        resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
        the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and
        deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

      

      

      
        37

        
          


      

      (c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights,
        powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

      

      

      (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

      

      

      Section 610 Merger, Conversion, Consolidation Or Succession To Business.

      

      

      Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the
        Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible
        under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities or coupons shall have been authenticated, but not delivered, by the Trustee then in office, any
        successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities or coupons so authenticated with the same effect as if such successor Trustee had itself authenticated such
        Securities or coupons. In case any Securities or coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities or coupons, in either its own name or that of its
        predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee.

      

      

      Section 611 Appointment Of Authenticating Agent.

      

      

      At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to
        act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption or repayment thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the
        benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, a copy
        of which instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be
        deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be reasonably
        acceptable to the Company and, except as may otherwise be provided pursuant to Section 301, shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of
        America or of any State or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State
        authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and
        surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with
        the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

      

      

      
        38

        
          


      

      Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
        which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be
        otherwise eligible under this Section, without the execution or filing of any paper or further act on the part of the Trustee or the Authenticating Agent.

      

      

      An Authenticating Agent for any series of Securities may at any time resign by giving written notice of resignation to the Trustee for such series and to the Company. The Trustee for any series of
        Securities may at any time terminate the agency of an Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case
        at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give
        notice of such appointment to all Holders of Securities of or within the series with respect to which such Authenticating Agent will serve in the manner set forth in Section 106. Any successor Authenticating Agent upon acceptance of its appointment
        hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under
        the provisions of this Section.

      

      

      The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation including reimbursement of its reasonable expenses for its services under this Section.

      

      

      If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee’s
        certificate of authentication, an alternate certificate of authentication substantially in the following form:

      

      

      This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

      

      

      	 	 	
              , as Trustee

            


      

      

      	 	
              By:

            	 	
              , as Authenticating Agent

            
	 	
              By:

            	 	
              , Authorized Officer

            


      

      

      Section 612 Certain Duties And Responsibilities.

      

      

      No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the
        exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not reasonably assured to it. Whether or not therein expressly
        so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

      

      

      Section 613 Conflicting Interests.

      

      

      If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner
        provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with
        respect to Securities of more than one series. In case an Event of Default shall occur and be continuing, the Trustee shall exercise such of its rights and powers under the applicable Indenture and use the same degree of care and skill in their
        exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

      

      

      Section 614 Preferential Collection Of Claims Against Company.

      

      

      If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection
        of claims against the Company (or any such other obligor).

      Every Holder of Securities or coupons, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any Authenticating Agent nor any
        Paying Agent nor any Security Registrar nor any director, officer, agent or employee of any of them shall be held accountable by reason of the disclosure of any information as to the names and addresses of the Holders of Securities or coupons in
        accordance with TIA Section 312, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA Section 312(b).

      

      

      Section 702 Reports By Trustee.

      

      

      Within 60 days after March 15 of each year commencing with the first March 15 after the first issuance of Securities pursuant to this Indenture, the Trustee shall transmit by mail to all Holders of
        Securities as provided in TIA Section 313(c) a brief report dated as of such March 15 if and to the extent required by TIA Section 313(a).

      

      

      A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with the Commission and with the Company and, provided the Trustee has received written
        notification by the Company that any Securities are listed on any stock exchange, with each stock exchange upon which the Trustee has been so notified that such Securities are listed.

      

      

      Section 703 Reports By Company.

      

      

      The Company will:

      

      

      (1) file with the Commission copies of annual reports, quarterly reports and other documents which the Company is required to file pursuant to Section 13 or 15(d) of the Exchange Act, and the
        Company will promptly, upon written request and payment of the reasonable cost of duplication and delivery, supply copies of such documents to any prospective Holder;

      

      

      (2) file with the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such additional information, documents and reports with respect to compliance
        by the Company with the conditions and covenants of this Indenture as may be required from time to time by such rules and regulations; and

      

      

      Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information
        contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

      

      

      Section 704 Company To Furnish Trustee Names And Addresses Of Holders.

      

      

      The Company will furnish or cause to be furnished to the Trustee:

        addresses of the Holders of Registered Securities of such series as of such Regular Record Date, or if there is no Regular Record Date for interest for such series of Securities, semi-annually, upon such dates as are set forth in the Board
        Resolution or indenture supplemental hereto authorizing such series, and

      

      

      (2) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15
        days prior to the time such list is furnished, provided, however, that, so long as the Trustee is the Security Registrar, no such lists shall be required to be furnished.

      Section 801 Consolidations And Mergers Of Company And Sales, Leases And Conveyances Permitted Subject To Certain Conditions.

      

      

      With respect to any series of Securities, the Company shall not consolidate with, or sell, lease, transfer, convey or otherwise dispose of all or substantially all of its assets, in one transaction
        or a series of related transactions, to, or merge with or into, any other Person, unless in any such case, (i) either the Company shall be the continuing entity, or the successor entity (if other than the Company) shall (a) be a corporation
        organized and existing under the laws of the United States of America, any State thereof, or the District of Columbia, and (b) expressly assume the due and punctual payment of the principal of (and premium or Make-Whole Amount, if any) and any
        interest (including all Additional Amounts, if any, payable pursuant to Section 1011) on all of the Securities of such series, according to their tenor, and the due and punctual performance and observance of all of the other covenants, conditions
        and obligations under such Securities and this Indenture (together with any supplement or supplemental indenture relating to such series of Securities) applicable to such series to be performed by the Company by supplemental indenture, complying
        with Article Nine hereof, satisfactory to the Trustee, executed and delivered to the Trustee by such Person, and the conversion or exchange rights shall be provided for in accordance with Article Sixteen, if applicable, or as otherwise specified
        pursuant to Section 301; and (ii) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Company or any Subsidiary as a result thereof as having been incurred by the Company or such
        Subsidiary at the time of such transaction, no Event of Default applicable to such series, and no event which, after notice or the lapse of time, or both, would become an Event of Default applicable to such series, shall have occurred and be
        continuing.

      

      

      For purposes of this Section 801, the sale, lease, transfer, conveyance or disposition of all or substantially all of the assets of one or more Subsidiaries of the Company to another Person, which
        assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all
        of the assets of the Company to another Person.

      

      

      Section 802 Rights And Duties Of Successor Corporation.

      

      

      In case of any such consolidation, merger, sale, lease or conveyance and upon any such assumption by the successor entity, such successor entity shall succeed to and be substituted for the Company,
        with the same effect as if it had been named herein as the party of the first part, and the predecessor entity, except in the event of a lease, shall be relieved of any further obligation applicable to such series under this Indenture and the
        Securities of such series. Such successor entity thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Securities of such series issuable hereunder which theretofore shall not have
        been signed by the Company and delivered to the Trustee; and, upon the order of such successor entity, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and
        shall deliver any Securities of such series which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Securities of such series which such successor entity thereafter shall cause
        to be signed and delivered to the Trustee for that purpose. All the Securities of such series so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities of such series theretofore or thereafter
        issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

      

      

      In case of any such consolidation, merger, sale, lease or conveyance, such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be
        appropriate.

        Securities in any material respect; or

      

      

      (10) to cure any ambiguity, to correct or supplement any provision herein which may be defective or inconsistent with any other provision herein, or to make any other provisions with respect to
        matters or questions arising under this Indenture which shall not be inconsistent with the provisions of this Indenture or to make any other changes, provided that in each case, such provisions shall not adversely affect the rights or interests of
        the Holders of Securities of any series or any related coupons in any material respect; or

      

      

      (11) to close this Indenture with respect to the authentication and delivery of additional series of Securities or to qualify, or maintain qualification of, this Indenture under the TIA; or

      (14) to make any change that does not adversely affect the rights or interests of any Holder of any Securities.

      

      

      Section 902 Supplemental Indentures With Consent Of Holders.

      

      

      Except as may otherwise be provided pursuant to Section 301 for all or any specific Securities of any series, with the consent of the Holders of not less than a majority in aggregate principal
        amount of all Outstanding Securities affected by such supplemental indenture, considered together as one class for this purpose (such affected Securities may be Securities of the same or different series and, with respect to any series, may
        comprise fewer than all the Securities of such series), by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee may enter into an indenture or indentures
        supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of such affected Securities and any related
        coupons under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby:

      

      

      (1) change the Stated Maturity of the principal of (or premium or Make-Whole Amount, if any, on) or any installment of principal of or interest on, any Security; or reduce the principal amount
        thereof or the rate or amount of interest thereon or any Additional Amounts payable in respect thereof, or any premium or Make-Whole Amount payable upon the redemption thereof, or change any obligation of the Company to pay Additional Amounts
        pursuant to Section 1011 (except as contemplated by Section 801(i) and permitted by Section 901(1)), or reduce the amount of the principal of an Original Issue Discount Security or Indexed Security or Make-Whole Amount, if any, that would be due
        and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable in bankruptcy pursuant to Section 504, or adversely affect any right of repayment at the option of the Holder of any
        Security, or change any Place of Payment where, or the currency or currencies, currency unit or units or composite currency or currencies in which, the principal of any Security or any premium or Make-Whole Amount or any Additional Amounts payable
        in respect thereof or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption or repayment at the option of the Holder, on
        or after the Redemption Date or the Repayment Date, as the case may be); or

      

      

      
        43

        
          


      

      (2) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose
        Holders is required for any waiver with respect to such series (or compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, or reduce the requirements of Section 1504
        for quorum or voting; or

      

      

      (3) modify any of the provisions of this Section, Section 513 or Section 1012, except to increase the required percentage to effect such action or to provide that certain other provisions of this
        Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby;

      

      

      (4) make any change that adversely affects the right to convert or exchange any Security as provided in Article Sixteen or pursuant to Section 301 (except as permitted by Section 901(9)) or
        decrease the conversion or exchange rate or increase the conversion or exchange price of any such Security; or

      

      

      (5) adversely affect the ranking of any Securities.

      

      

      It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the
        substance thereof.

      

      

      A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included for the benefit of one or more particular series of
        Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

      

      

      Section 903 Execution Of Supplemental Indentures.

        conditions precedent to the execution of such supplemental indenture have been complied with. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities

      Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture
        for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder and of any coupon appertaining thereto shall be bound thereby.

      

      

      Section 905 Conformity With Trust Indenture Act.

      

      

      Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect.

      

      

      Section 906 Reference In Securities To Supplement Indentures.

      

      

      Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form
        approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental
        indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

      COVENANTS

      

      

      Section 1001 Payment Of Principal, Premium Or Make-Whole Amount, If Any, Interest And Additional Amounts.

      

      

      The Company covenants and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the principal of (and premium or Make-Whole Amount, if any) and
        interest on and any Additional Amounts payable in respect of the Securities of that series in accordance with the terms of such series of Securities, any coupons appertaining thereto and this Indenture. Unless otherwise specified as contemplated by
        Section 301 with respect to any series of Securities, any interest due on and any Additional Amounts payable in respect of Bearer Securities on or before Maturity, other than Additional Amounts, if any, payable as provided in Section 1011 in
        respect of principal of (or premium or Make-Whole Amount, if any, on) such a Security, shall be payable only upon presentation and surrender of the several coupons for such interest installments as are evidenced thereby as they severally mature.
        Unless otherwise specified with respect to Securities of any series pursuant to Section 301, at the option of the Company, all payments of principal may be paid by check to the registered Holder of the Registered Security or other person entitled
        thereto against surrender of such Security.

      

      

      Section 1002 Maintenance Of Office Or Agency.

      

      

      If Securities of a series are issued as Registered Securities, the Company shall maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series
        may be presented or surrendered for payment or conversion, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be converted or exchanged in accordance with Article
        Sixteen, and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issued as Bearer Securities, the Company will maintain: (A) in the City of
        Oklahoma City, Oklahoma, or in the Borough of Manhattan, The City of New York, an office or agency where any Registered Securities of that series may be presented or surrendered for payment or conversion, where any Registered Securities of that
        series may be surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or
        surrendered for payment or conversion in the circumstances described in the following paragraph (and not otherwise); (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the
        United States, an office or agency where Securities of that series and related coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Securities of that series pursuant to Section 1011) or
        conversion.

      

      

      Unless otherwise specified with respect to any Securities pursuant to Section 301, no payment of principal, premium, Make-Whole Amount or interest on or Additional Amounts in respect of Bearer
        Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States; provided, however, that,
        if the Securities of a series are payable in Dollars, payment of principal of and any premium and interest on any Bearer Security (including any Additional Amounts or Make-Whole Amount payable on Securities of such series pursuant to Section 1011)
        shall be made at the office of the Company’s Paying Agent in the City of Oklahoma City, Oklahoma, or the Borough of Manhattan, The City of New York, if (but only if) payment in Dollars of the full amount of such principal, premium, interest,
        Additional Amounts or Make-Whole Amount, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture, is illegal or effectively precluded by exchange controls
        or other similar restrictions.

      

      

      
        45

        
          


      

      The Company may from time to time designate one or more other offices or agencies where the Securities of one or more series and related coupons, if any, may be presented or surrendered for any or
        all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the
        requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

      

      

      Unless otherwise specified with respect to any Securities pursuant to Section 301 with respect to a series of Securities, the Company hereby designates as a Place of Payment for each series of
        Securities the office or agency of the Company in the contiguous United States, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent and as its agent to receive all such presentations, surrenders, notices and demands;
        provided that, the Corporate Trust Office shall not be an office or agency of the Company for service of legal process on the Company.

      

      

      Unless otherwise specified with respect to any Securities pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in
        a Foreign Currency, or so long as it is required under any other provision of the Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent.

      

      

      Section 1003 Money For Securities Payments To Be Held In Trust.

      

      

      If the Company shall at any time act as its own Paying Agent with respect to any series of any Securities and any related coupons, it will, on or before each due date of the principal of (and
        premium or Make-Whole Amount, if any), or interest on or Additional Amounts in respect of, any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies,
        currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (and premium or
        Make-Whole Amount, if any) or interest or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to act.

      

      

      Whenever the Company shall have one or more Paying Agents for any series of Securities and any related coupons, it will, on or before each due date of the principal of (and premium or Make-Whole
        Amount, if any), or interest on or Additional Amounts in respect of, any Securities of that series, deposit with a Paying Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the
        preceding paragraph) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or interest or Additional Amounts, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium,
        Make-Whole Amount or interest or Additional Amounts and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

      

      

      The Company will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
        provisions of this Section, that such Paying Agent will:

      

      

      (1) hold all sums held by it for the payment of principal of (and premium or Make-Whole Amount, if any) or interest on Securities or Additional Amounts in trust for the benefit of the Persons
        entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

      

      

      (2) give the Trustee written notice of any default by the Company (or any other obligor upon the Securities) in the making of any such payment of principal (and premium or Make-Whole Amount, if
        any) or interest or Additional Amounts; and

      

      

      (3) at any time during the continuance of any such default upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

      

      

      
        46

        
          


      

      The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the
        Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to
        the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

      

      

      Except as otherwise provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of
        (and premium or Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect of, any Security of any series and remaining unclaimed for two years after such principal (and premium or Make-Whole Amount, if any), interest or
        Additional Amounts has become due and payable shall be paid to the Company upon Company Request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general
        creditor, look only to the Company for payment of such principal of (and premium or Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect of, any Security, without interest thereon, and all liability of the Trustee or such
        Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the
        expense of the Company cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed
        balance of such money then remaining will be repaid to the Company.

      

      

      Section 1004 Existence.

      

      

      Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence as a corporation.

      

      

      Section 1005 Statement As To Compliance.

      

      

      The Company will deliver to the Trustee within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal
        accounting officer as to his or her knowledge of the Company’s compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof. For purposes
        of this Section 1010, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

      

      

      Section 1006 Additional Amounts.

      

      

      If any Securities of a series provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series or any coupon appertaining thereto Additional Amounts
        as may be specified as contemplated by Section 301. Whenever in this Indenture there is mentioned, in any context except in the case of Section 502(1), the payment of the principal of or any premium, Make-Whole Amount or interest on, or in respect
        of, any Security of any series or payment of any related coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the
        terms of such series established pursuant to Section 301 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express mention of the payment of Additional Amounts (if
        applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

      

      

      
        47

        
          


      

      Except as otherwise specified as contemplated by Section 301, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date
        with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least 10 days prior to each date of payment of
        principal and any premium or Make-Whole Amount or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company will furnish the Trustee and the Company’s principal Paying
        Agent or Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall
        be made to Holders of Securities of that series or any related coupons who are not United States Persons without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of or within the series.
        If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities of that series or related coupons and the Company will
        pay to the Trustee or such Paying Agent the Additional Amounts, if any, required by the terms of such Securities. In the event that the Trustee or any Paying Agent, as the case may be, shall not so receive the above mentioned certificate, then the
        Trustee or such Paying Agent shall be entitled (i) to assume that no such withholding or deduction is required with respect to any payment of principal or interest with respect to any Securities of a series or related coupons until it shall have
        received a certificate advising otherwise and (ii) to make all payments of principal and interest with respect to the Securities of a series or related coupons without withholding or deductions until otherwise advised. The Company covenants to
        indemnify the Trustee and any Paying Agent and their respective officers, directors, employees and agents for, and to hold them harmless against, any loss, liability or expense (including legal fees and expenses) reasonably incurred without gross
        negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section or in reliance on the Company’s not furnishing such an
        Officers’ Certificate.

      

      

      Section 1007 Waiver Of Certain Covenants.

      

      

      The Company may omit in any particular instance to comply with any covenant set forth in Section 1004 or any covenants of the Company added to this Article Ten pursuant to Section 301(14) or
        Section 301(15) in connection with the Securities of a series (except any such term, provision or condition which could not be amended without the consent of Holders of all Securities of such series pursuant to Section 902 or the specific terms of
        such series), if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of all Outstanding Securities of such series, by Act of such Holders, either waive such compliance in such instance or
        generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the
        Company and the duties of the Trustee in respect of any such covenant shall remain in full force and effect.

      

      

      ARTICLE ELEVEN

      REDEMPTION OF SECURITIES

      

      

      Section 1101 Applicability Of Article.

      

      

      Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for
        Securities of any series) in accordance with this Article.

      

      

      Section 1102 Election To Redeem; Notice To Trustee.

      

      

      The election of the Company to redeem any Securities, including coupons, if any shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company,
        the Company shall, at least 30 days and not more than 60 days prior to the giving of the notice of redemption in Section 1104 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee, in writing, of such Redemption Date,
        Redemption Price and of the principal amount of Securities of the series to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere
        in this Indenture or pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officers’ Certificate and Opinion of Counsel evidencing compliance
        with such restriction or condition.

      Section 1103 Selection By Trustee Of Securities To Be Redeemed.

      

      

      If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from
        the Outstanding Securities of such series issued on such date with the same terms not previously called for redemption, pro rata, by lot or by such method as the Trustee shall deem fair and appropriate and in the case of global Securities, in
        accordance with the procedures of the Depository; provided that such method complies with the rules of any national securities exchange or quotation system on which the Securities are listed, and which may provide for the selection for redemption
        of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple permitted by such Securities of that series) of the principal amount of Securities of such series of a denomination larger than the
        minimum authorized denomination for Securities of that series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for
        Securities of such series. The Trustee shall make the selection from Securities of the series that are Outstanding and that have not previously been called for redemption and may provide for the selection for redemption of portions (equal to the
        minimum authorized denomination for Securities, including coupons, if any, of that series or any integral multiple permitted by such Securities of that series).

      

      

      If any Security selected for partial redemption is converted in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted or
        exchanged portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as
        Outstanding for the purpose of such selection. In any case where more than one Security is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security.

      

      

      The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for
        partial redemption, the principal amount thereof to be redeemed.

      

      

      For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be
        redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

      

      

      Section 1104 Notice Of Redemption.

      

      

      Notice of redemption shall be given in the manner provided in Section 106, not less than 30 days nor more than 60 days prior to the Redemption Date, unless a shorter period is specified by the
        terms of such series established pursuant to Section 301, to each Holder of Securities to be redeemed, but failure to give such notice in the manner herein provided to the Holder of any Security designated for redemption as a whole or in part, or
        any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Security or portion thereof.

      

      

      Any notice that is mailed to the Holders of Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the
        notice.

      

      

      All notices of redemption shall state:

      

      

      (1) the Redemption Date;

      

      

      (2) the Redemption Price (or if not then ascertainable, the manner of calculation thereof), accrued interest to the Redemption Date payable as provided in Section 1106, if any, and Additional
        Amounts, if any;

      

      

      (3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or
        Securities to be redeemed;

      

      

      (4) in case any Security is to be redeemed in part only, that on and after the Redemption Date, upon surrender of such Security, the holder will receive, without a charge, a new Security or
        Securities of authorized denominations for the principal amount thereof remaining unredeemed;

      

      

      
        49

        
          


      

      (5) that on the Redemption Date the Redemption Price and accrued interest to the Redemption Date payable as provided in Section 1106, if any, will become due and payable upon each such Security, or
        the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date;

      

      

      (6) the Place or Places of Payment where such Securities, together in the case of Bearer Securities with all coupons appertaining thereto, if any, maturing after the Redemption Date, are to be
        surrendered for payment of the Redemption Price and accrued interest, if any, or for conversion or exchange;

      

      

      (7) that the redemption is for a sinking fund, if such is the case;

      

      

      (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all coupons maturing subsequent to the date fixed for
        redemption or the amount of any such missing coupon or coupons will be deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee for such series and any Paying Agent is furnished;

      

      

      (9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered
        Securities not subject to the redemption on this Redemption Date pursuant to Section 305 or otherwise, the last date, as determined by the Company, on which such exchanges may be made;

      

      

      (10) the CUSIP number of such Security, if any, provided that neither the Company nor the Trustee shall have any responsibility for any such CUSIP number; and

      

      

      (11) if applicable, that a Holder of Securities who desires to convert or exchange Securities to be redeemed must satisfy the requirements for conversion or exchange contained in such Securities,
        the then existing conversion or exchange price or rate and the date and time when the option to convert or exchange shall expire and the place or places where such Securities may be surrendered for conversion.

      

      

      Notice of redemption of Securities to be redeemed shall be given by the Company or, at the Company’s written request, by the Trustee in the name and at the expense of the Company.

      

      

      Section 1105 Deposit Of Redemption Price.

      

      

      On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, which it may not do in the case of a
        sinking fund payment under Article Twelve, segregate and hold in trust as provided in Section 1003) an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series
        are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay on the Redemption Date the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
        interest on, all the Securities or portions thereof which are to be redeemed on that date.

      

      

      Section 1106 Securities Payable On Redemption Date.

      

      

      Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified in the currency
        or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) (together with accrued interest,
        if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall, if the same were interest-bearing, cease to bear interest and the
        coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Except as provided in the next succeeding paragraph, upon surrender of any such Security for redemption in
        accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption
        Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in
        Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of coupons for such interest; and provided further that except as otherwise provided with respect to Securities convertible or
        exchangeable into other securities or property of the Company, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more
        Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

      

      

      
        50

        
          


      

      If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the
        Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may
        require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the
        Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest (and any Additional Amounts) represented by coupons shall be payable only at an office or agency located outside the United States
        (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons. If any Security called for redemption shall not be so paid upon surrender thereof
        for redemption, the principal, (and premium or Make-Whole Amount, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

      

      

      Section 1107 Securities Redeemed In Part.

      

      

      Any Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered at a Place of Payment therefor (with, if the Company or the
        Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the
        Trustee shall authenticate and deliver to the Holder of such Security without service charge a new Security or Securities of the same series, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in
        exchange for the unredeemed portion of the principal of the Security so surrendered.

      

      

      ARTICLE TWELVE

      SINKING FUNDS

      

      

      Section 1201 Applicability Of Article.

      

      

      The provisions of this Article Twelve shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 301 for
        Securities of such series.

      

      

      The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such
        minimum amount provided for by the terms of such Securities of any series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities of any series, the cash amount of any mandatory sinking fund
        payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

      

      

      Section 1202 Satisfaction Of Sinking Fund Payments With Securities.

      

      

      The Company may, in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of a series, (1) deliver Outstanding Securities of such series (other than
        any previously called for redemption) together in the case of any Bearer Securities of such series with all unmatured coupons appertaining thereto and (2) apply as a credit Securities of such series which have been redeemed either at the election
        of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, as provided for by the terms of such Securities, or which have otherwise been
        acquired by the Company; provided that such Securities so delivered or applied as a credit have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the applicable Redemption Price
        specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

      Section 1203 Redemption Of Securities For Sinking Fund.

      

      

      Not less than 60 days prior to each sinking fund payment date for Securities of any series, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next
        ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the currency or currencies, currency unit or units or composite currency or
        currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities
        of that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so delivered and credited. If such Officers’
        Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not more than 60 nor less than 30 days before each
        such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the
        expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 1106 and Section 1107.

      

      

      ARTICLE THIRTEEN

      REPAYMENT AT THE OPTION OF HOLDERS

      

      

      Section 1301 Applicability Of Article.

      

      

      Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities, if any, and (except as otherwise
        specified by the terms of such series established pursuant to Section 301) in accordance with this Article Thirteen.

      

      

      Section 1302 Repayment Of Securities.

      

      

      Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities, be repaid at a Repayment
        Price equal to the principal amount thereof, together with interest, if any, thereof accrued and unpaid to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that on or before the Repayment Date it
        will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the currency or currencies, currency unit or units or
        composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (or, if so provided by the terms of the
        Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest on, all the Securities or portion thereof, as the case may be, to be repaid on such date.

      

      

      
        52

        
          


      

      Section 1303 Exercise Of Option.

      

      

      Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form on the Securities. In order for any Security to be repaid at the
        option of the Holder, the Trustee must receive at the Place of Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not
        earlier than 60 days nor later than 30 days prior to the Repayment Date (1) the Security so providing for such repayment together with the “Option to Elect Repayment” form duly completed by the Holder (or by the Holder’s attorney duly authorized in
        writing) or (2) a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority, Inc., or a commercial bank or trust company in the United States setting forth
        the name of the Holder of the Security, the principal amount of the Security, the principal amount of the Security to be repaid, the CUSIP number, if any, or a description of the tenor and terms of the Security, a statement that the option to elect
        repayment is being exercised thereby and a guarantee that the Security to be repaid, together with the duly completed form entitled “Option to Elect Repayment” the Security, will be received by the Trustee not later than the third Business Day
        after the date of such telegram, telex, facsimile transmission or letter; provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such Security and form duly completed are received by the Trustee by
        such third Business Day. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments of the minimum denomination for
        Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such Security surrendered that is not to be repaid, must be specified. The
        principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination
        of Securities of or within the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by
        the Holder shall be irrevocable.

      

      

      Section 1304 When Securities Presented For Repayment Become Due And Payable.

      

      

      If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article Thirteen and as provided by or pursuant to the terms
        of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the
        Company shall default in the payment of such Securities on such Repayment Date) such Securities for the portion thereof, shall, if the same were interest bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer
        Securities so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, together with all coupons, if any, appertaining thereto maturing after the
        Repayment Date, the Repayment Price shall be paid by the Company; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except as
        otherwise provided in Section 1002) and, unless otherwise specified pursuant to Section 301, only upon presentation and surrender of such coupons; and provided further that, in the case of Registered Securities, installments of interest, if any,
        whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company shall default in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered
        as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.  Surrender of Securities which are to be repaid in part only shall also be subject to Section 1305.

      

      

      If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date, such Security may be paid after deducting from the amount
        payable therefor as provided in Section 1302 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such security
        or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have
        been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States
        (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons. If the principal amount of any Security surrendered for repayment shall not be so
        repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of
        Original Issue Discount Securities) set forth in such Security.

      Section 1305 Securities Repaid In Part.

      

      

      Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without
        service charge and at the expense of the Company, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the
        principal of such Security so surrendered which is not to be repaid.

      

      

      ARTICLE FOURTEEN

      DEFEASANCE AND COVENANT DEFEASANCE

      

      

      Section 1401 Applicability Of Article; Company’s Option To Effect Defeasance Or Covenant Defeasance.

      

      

      If, pursuant to Section 301, provision is made for either or both of (a) defeasance of the Securities of or within a series under Section 1402 or (b) covenant defeasance of the Securities of or
        within a series under Section 1403 to be applicable to the Securities of any series, then the provisions of such Section or Sections, as the case may be, together with the other provisions of this Article Fourteen (with such modifications thereto
        as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any coupons appertaining thereto, and the Company may at its option by Board Resolution at any time, with respect to such
        Securities and any coupons appertaining thereto, elect to defease such Outstanding Securities and coupons appertaining thereto pursuant to Section 1402 (if applicable) or Section 1403 (if applicable) upon compliance with the conditions set forth
        below in this Article.

      

      

      Section 1402 Defeasance And Discharge.

      

      

      Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its
        obligations with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the
        Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1405
        and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all of its other obligations under such Securities and any coupons appertaining thereto and this Indenture insofar as such Securities and any
        coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder:
        (A) the rights of Holders of such Outstanding Securities and any coupons appertaining thereto to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments in respect of the principal of (and
        premium or Make-Whole Amount, if any) and interest, if any, on such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with respect to such Securities under Section 305, Section 306, Section
        1002 and Section 1003 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1011, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Fourteen.
        Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 1403 with respect to such Securities and any coupons appertaining thereto.

      

      

      Section 1403 Covenant Defeasance.

      

      

      Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be released from its obligations under Section
        1004 and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the conditions set forth in Section 1404 are satisfied
        (hereinafter, “covenant defeasance”), and such Securities and any coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the
        consequences of any thereof) in connection with Section 1004, or such other covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such
        Outstanding Securities and any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other covenant, whether directly or
        indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission to
        comply shall not constitute a default or an Event of Default under Section 501(4) or Section 501(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and any coupons appertaining
        thereto shall be unaffected thereby.

      Section 1404 Conditions To Defeasance Or Covenant Defeasance.

      

      

      The following shall be the conditions to application of Section 1402 or Section 1403 to any Outstanding Securities of or within a series and any coupons appertaining thereto:

      

      

      (a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to comply with the
        provisions of this Article Fourteen applicable to it) 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 such Securities and any
        coupons appertaining thereto:

      

      

      (1) an amount in such currency, currencies or currency unit in which such Securities and any coupons appertaining thereto are then specified as payable at Stated Maturity,

      

      

      (2) if Securities of such series are not subject to early repayment at the option of the Holders, United States Government Obligations applicable to such Securities and coupons
        appertaining thereto (determined on the basis of the currency, currencies or currency unit in which such Securities and coupons appertaining thereto are then specified as payable at Stated Maturity) 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 of principal of (and premium or Make-Whole Amount, if any) and interest, if any, and Additional Amounts, if any,
        on such Securities and any coupons appertaining thereto, money in an amount, or

      

      

      (3) a combination thereof,

      

      

      in each case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants
        expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge: (i) the principal of (and premium or Make-Whole Amount, if
        any) and interest, if any, and Additional Amounts, if any on such Outstanding Securities and any coupons appertaining thereto on the Stated Maturity of such principal or installment of principal or interest and (ii) any mandatory sinking fund
        payments or analogous payments applicable to such Outstanding Securities and any coupons appertaining thereto on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any
        coupons appertaining thereto; provided, that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such United States Government Obligations to said payments with respect to such Securities. Before such a
        deposit, the Company may give to the Trustee, in accordance with Section 1102 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such
        series and Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

      

      

      (b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a breach or default under, this Indenture or any other material agreement or instrument to
        which the Company is a party or by which it is bound (and shall not cause the Trustee to have a conflicting interest pursuant to Section 310(b) of the TIA with respect to any Security of the Company).

      

      

      (c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any coupons appertaining thereto shall have occurred
        and be continuing on the date of such deposit or, insofar as Section 501(6) and Section 501(7) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be
        deemed satisfied until the expiration of such period).

      

      

      
        55

        
          


      

      (d) In the case of an election under Section 1402, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the beneficial owners of such Outstanding Securities and
        any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts (including, without limitation, principal,
        premium, if any, any Make-Whole Amounts, if any, Additional Amounts, if any, and interest), in the same manner and at the same times as would have been the case if such defeasance had not occurred, which Opinion of Counsel must be based upon a
        ruling of the Internal Revenue Service to the same effect unless there has been a change in applicable Federal income tax law after the date of execution of this Indenture such that a ruling is no longer required;

      

      

      (e) In the case of an election under Section 1403, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the beneficial owners of such Outstanding Securities and
        any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts (including, without limitation,
        principal, premium, if any, any Make-Whole Payments, if any, Additional Amounts, if any, and interest) in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

      

      

      (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance under Section 1402 or the
        covenant defeasance under Section 1403 (as the case may be) have been complied with and an Opinion of Counsel to the effect that either (i) as a result of a deposit pursuant to subsection (a) above and the related exercise of the Company’s option
        under Section 1402 or Section 1403 (as the case may be) registration is not required under the Investment Company Act of 1940, as amended, by the Company, with respect to the trust funds representing such deposit or by the Trustee for such trust
        funds or (ii) all necessary registrations under said Act have been effected.

      

      

      (g) After the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights
        generally, including, without limitation, Section 547 of the United States Bankruptcy Code and Section 15 of the New York Debtor and Creditor Law.

      

      

      (h) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations
        which may be imposed on the Company in connection therewith pursuant to Section 301.

      

      

      Section 1405 Deposited Money And Government Obligations To Be Held In Trust; Other Miscellaneous Provisions.

      

      

      Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds thereof)
        deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405, the “Trustee”) pursuant to Section 1404 in respect of any Outstanding Securities of any series and any coupons appertaining thereto shall be
        held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its
        own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium or Make-Whole Amount, if any) and interest and
        Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

      

      

      
        56

        
          


      

      Unless otherwise specified with respect to any Security pursuant to Section 301, if, after a deposit referred to in Section 1404(a) has been made, (a) the Holder of a Security in respect of which
        such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a currency or currency unit other than that in which the deposit pursuant to Section 1404(a) has been made in respect
        of such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which the deposit pursuant to Section 1404(a) has been made, the indebtedness represented by such Security and any coupons appertaining thereto shall
        be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium or Make-Whole Amount, if any), and interest, if any, on such Security as the same becomes due out of the proceeds yielded by
        converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the currency or currency unit in which such Security becomes payable as a result of such
        election or Conversion Event based on the applicable market exchange rate for such currency or currency unit in effect on the second Business Day prior to each payment date, except, with respect to a Conversion Event, for such currency or currency
        unit in effect (as nearly as feasible) at the time of the Conversion Event.

      

      

      The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 1404 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 such Outstanding Securities and any coupons appertaining thereto.

      

      

      Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other
        property and any proceeds therefrom) held by it as provided in Section 1404 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess
        of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Article.

      

      

      Section 1406 Reinstatement.

      

      

      If the Trustee or the Paying Agent is unable to apply any money or the Government Obligations, as the case may be, in accordance with this Article Fourteen with respect to any Securities by reason
        of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture, such Securities and any coupons appertaining thereto from which the Company
        has been discharged or released pursuant to Section 1402 or Section 1403 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is
        permitted to apply all money or Government Obligations, as the case may be, held in trust pursuant to Section 1405 with respect to such Securities and any coupons appertaining thereto in accordance with this Article Fourteen; provided, however,
        that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities or
        coupons to receive such payment from the money or Government Obligations, as the case may be, so held in trust.

      

      

      Section 1407 Qualifying Trustee.

      

      

      Any trustee appointed pursuant to Section 1404 for the purpose of holding trust funds deposited pursuant to that Section shall be appointed under an agreement in form acceptable to the Trustee and
        shall provide to the Trustee a certificate of such trustee, upon which certificate the Trustee shall be entitled to conclusively rely, that all conditions precedent provided for herein to the related defeasance or covenant defeasance have been
        complied with. In no event shall the Trustee be liable for any acts or omissions of said trustee.

      (b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in
        Section 1502(b), in which case the Company or the Holders of Securities of or within the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the

        by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right
        to vote, except as a Holder of a Security of such series or proxy.

        aggregate principal amount of the Outstanding Securities of such series represented at the meeting, and the meeting may be held as so adjourned without further notice.

        of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by agent duly appointed in writing; and, except as herein otherwise
        expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this
        Indenture and (subject to Sections 315(a) through 315(d) of the TIA) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Article.

        the Company has made such election.

      Section 1603 No Fractional Shares.

      

      

      No fractional shares of securities shall be delivered upon exchanges of Securities of any series. If more than one Security shall be surrendered for exchange at one time by the same Holder, the
        number of full shares which shall be delivered upon exchange shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If, except for the
        provisions of this Section 1603, any Holder of a Security or Securities would be entitled to a fractional share of a security upon the exchange of such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an
        amount in cash equal to the current market value of such fractional share computed on the basis of an average Closing Price of such security. The “Closing Price” of any security on any date of determination means, (i) if such security is listed or
        admitted to unlisted trading privileges on a national securities exchange, the last reported sale price regular way on such exchange, (ii) if such security is not at the time so listed, as reported by the NASDAQ National Market, or (iii) if such
        security is not at the time so listed or reported or admitted to unlisted trading privileges on a national securities exchange, the average of the bid and asked prices of such security in the over-the-counter market, as reported by the National
        Quotation Bureau, Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer reporting such information, or if not so available, the market price as determined by a nationally recognized independent investment
        banking firm retained for this purpose by the Company.

      

      

      Section 1604 Adjustment Of Exchange Rate.

      

      

      The exchange rate of Securities of any series that is exchangeable for other securities or property (including securities of other issuers, provided that such securities are registered under
        Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company shall be adjusted for any stock dividends, stock splits, reclassification, combinations
        or similar transactions or any consolidation, merger or other reorganization event in accordance with the terms of the supplemental indenture or Board Resolution setting forth the terms of the Securities of such series.

      

      

      Whenever the exchange rate is adjusted, the Company shall compute the adjusted exchange rate in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare
        an Officers’ Certificate setting forth the adjusted exchange rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of
        exchange of Securities pursuant to Section 1002 and, if different, with the Trustee. The Company shall forthwith cause a notice setting forth the adjusted exchange rate to be mailed, first class postage prepaid, to each Holder of Securities of such
        series at its address appearing on the Security Register and to any exchange agent other than the Trustee.

      

      

      Section 1605 Payment Of Certain Taxes Upon Exchange.

      

      

      The Company will pay any and all taxes that may be payable in respect of the transfer and delivery of shares of other securities or property (including securities of other issuers, provided that
        such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company on exchange of Securities pursuant hereto. The
        Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the delivery of shares of securities in a name other than that of the Holder of the Security or Securities to be exchanged, and no
        such transfer or delivery shall be made unless and until the Person requesting such transfer has paid to the Company the amount of any such tax, or has established, to the satisfaction of the Company, that such tax has been paid.

      

      

      Section 1606 Shares Free And Clear.

      

      

      The Company hereby warrants that upon exchange of Securities of any series, the Holder of a Security shall receive all rights held by the Company in such security for which such Security is at such
        time exchangeable under this Article Sixteen, free and clear of any and all liens, claims, charges and encumbrances other than, to the extent permitted by the terms of the Securities of such series, any liens, claims, charges and encumbrances which
        may have been placed on any such security by the prior owner thereof, prior to the time such security was acquired by the Company. Except as provided in Section 1604, the Company will pay all taxes and charges with respect to the delivery of such
        security delivered in exchange for Securities hereunder.

      

      

      Section 1607 Cancellation Of Security.

      

      

      Upon receipt by the Trustee of Securities of any series delivered to it for exchange under this Article Sixteen, the Trustee shall cancel and dispose of the same as provided in Section 309.

      Section 1608 Duties Of Trustee Regarding Exchange.

      

      

      Neither the Trustee nor any exchange agent shall at any time be under any duty or responsibility to any Holder of Securities of any series that is exchangeable into other securities or property
        (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the
        Company to determine whether any facts exist which may require any adjustment of the exchange rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, whether herein or in any
        supplemental indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company provided to be employed in making the same. Neither the Trustee nor any exchange agent shall be accountable with
        respect to the validity or value (or the kind or amount) of any securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use
        Form S-3 (or any successor form) for a primary offering of its securities) of the Company, or of any Securities and neither the Trustee nor any exchange agent makes any representation with respect thereto. Subject to the provisions of Section 612,
        neither the Trustee nor any exchange agent shall be responsible for any failure of the Company to issue, transfer or deliver any stock certificates or other securities or property (including securities of other issuers, provided that such
        securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) upon the surrender of any Security for the purpose of exchange or to
        comply with any of the covenants of the Company contained in this Article Sixteen or in the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized officers of the
        Company.

      

      

      Section 1609 Repayment Of Certain Funds Upon Exchange.

      

      

      Any funds which at any time shall have been deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any, and
        interest, if any, on any of the Securities (including funds deposited for the sinking fund referred to in Article Twelve hereof) and which shall not be required for such purposes because of the exchange of such Securities as provided in this
        Article Sixteen shall after such exchange be repaid to the Company by the Trustee upon the Company’s written request.

      

      

      Section 1610 Exercise Of Conversion Privilege.

      

      

      In order to exercise a conversion or exchange privilege, the Holder of a Security of a series with such a privilege shall surrender such Security to the Company at the office or agency maintained
        for that purpose pursuant to Section 1002, accompanied by written notice to the Company that the Holder elects to convert or exchange such Security or a specified portion thereof. Such notice shall also state, if different from the name or names
        (with address) in which the Securities are registered, the name or names in which the securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer
        is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company which shall be issuable on such conversion or exchange shall be issued. Securities surrendered for conversion or exchange shall (if so
        required by the Company or the Trustee) be duly endorsed by or accompanied by instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the registered Holder or its attorney duly authorized in writing; and
        Securities so surrendered for conversion or exchange during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof called
        for redemption during such period) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security then being converted, and
        such interest shall be payable to such registered Holder notwithstanding the conversion or exchange of such Security, subject to the provisions of Section 307 relating to the payment of Defaulted Interest by the Company. As promptly as practicable
        after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject to Section 303, set forth, or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures
        supplemental hereto setting forth the terms of such series of Security, and the surrender of such Security in accordance with such reasonable regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or
        agency at which such Security is surrendered, to such Holder or on its written order, securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer
        is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company issuable or deliverable upon the conversion or exchange of such Security (or specified portion thereof), in accordance with the
        provisions of such Board Resolution, Officers’ Certificate or supplemental indenture, and cash as provided therein in respect of any fractional share of such common stock otherwise issuable upon such conversion or exchange. Such conversion or
        exchange shall be deemed to have been effected immediately prior to the close of business on the date on which such notice and such payment, if required, shall have been received in proper order for conversion or exchange by the Company and such
        Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered such Security and shall have instructed the Company to effect the conversion or exchange on a particular date following such surrender and such Holder
        shall be entitled to convert or exchange such Security on such date, in which case such conversion or exchange shall be deemed to be effected immediately prior to the close of business on such date) and at such time the rights of the Holder of such
        Security as such Security Holder shall cease and the person or persons in whose name or names any securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and
        such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company shall be issuable or deliverable upon such conversion or exchange shall be deemed to have become the Holder or Holders of
        record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 307, no payment or adjustment shall be made upon any conversion or exchange on account of any interest accrued on the Securities
        surrendered for conversion or exchange or on account of any interest or dividends on the securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such
        issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company issued or delivered upon such conversion or exchange.

      

      

      
        62

        
          


      

      In the case of any Security which is converted or exchanged in part only, upon such conversion or exchange the Company shall execute and the Trustee shall authenticate and deliver to or on the
        order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the unconverted or unexchanged portion of such Security.

      

      

      Section 1611 Effect Of Consolidation Or Merger On Conversion Privilege.

      

      

      In case of any consolidation of the Company with, or merger of the Company into or with any other Person, or in case of any sale of all or substantially all of the assets of the Company, the
        Company or the Person formed by such consolidation or the Person into which the Company shall have been merged or the Person which shall have acquired such assets, as the case may be, shall execute and deliver to the Trustee a supplemental
        indenture providing that the Holder of each Security then outstanding of any series that is convertible into common stock of the Company shall have the right, which right shall be the exclusive conversion right thereafter available to said Holder
        (until the expiration of the conversion right of such Security), to convert such Security into the kind and amount of shares of stock or other securities or property (including cash) receivable upon such consolidation, merger or sale by a holder of
        the number of shares of common stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger or sale, subject to compliance with the other provisions of this Indenture, such Security and
        such supplemental indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in such Security. The above provisions of this Section shall similarly
        apply to successive consolidations, mergers or sales. It is expressly agreed and understood that anything in this Indenture to the contrary notwithstanding, if, pursuant to such merger, consolidation or sale, holders of outstanding shares of common
        stock of the Company do not receive shares of common stock of the surviving corporation but receive other securities, cash or other property or any combination thereof, Holders of Securities shall not have the right to thereafter convert their
        Securities into common stock of the surviving corporation or the corporation which shall have acquired such assets, but rather, shall have the right upon such conversion to receive the other securities, cash or other property receivable by a holder
        of the number of shares of common stock of the Company into which the Securities held by such holder might have been converted immediately prior to such consolidation, merger or sale, all as more fully provided in the first sentence of this Section
        1611. Anything in this Section 1611 to the contrary notwithstanding, the provisions of this Section 1611 shall not apply to a merger or consolidation of another corporation with or into the Company pursuant to which both of the following conditions
        are applicable: (i) the Company is the surviving corporation and (ii) the outstanding shares of common stock of the Company are not changed or converted into any other securities or property (including cash) or changed in number or character or
        reclassified pursuant to the terms of such merger or consolidation.

      

      

      
        63

        
          


      

      As evidence of the kind and amount of shares of stock or other securities or property (including cash) into which Securities may properly be convertible after any such consolidation, merger or
        sale, or as to the appropriate adjustments of the conversion prices applicable with respect thereto, the Trustee shall be furnished with and may accept the certificate or opinion of an independent certified public accountant with respect thereto;
        and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely thereon, and shall not be responsible or accountable to any Holder of Securities for any provision in conformity therewith or approved by such
        independent certified accountant which may be contained in said supplemental indenture.

      

      

      This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same
        Indenture.

      IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed by their respective officers hereunto duly authorized, all as of the day and year first above written.

        account or for resale, or (b) United States person(s) who acquired the Securities through foreign branches of United States financial institutions and who hold the Securities through such United States financial institutions on the date hereof (and
        in either case (a) or (b), each such United States financial institution hereby agrees, on its own behalf or through its agent, that you may advise Bank7 Corp. or its agent that such financial institution will comply with the requirements of
        Section 165(j)(3)(A), (B) or (C) of the United States Internal Revenue Code of 1986, as amended, and the regulations thereunder), or (iii) are owned by United States or foreign financial institution(s) for purposes of resale during the restricted
