        be construed to render ineffective any action taken at any time by the Holders (or their duly appointed agents) of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is so taken.  Notwithstanding
        the foregoing or the Trust Indenture Act, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any notice, declaration or direction referred to in the next paragraph.

        any record date is set pursuant to this paragraph, the Trustee shall notify the Company and the Holders of Outstanding Securities of such series of any such record date so fixed and the proposed action.  The Holders of Outstanding Securities of
        such series on such record date (or their duly appointed agents), and only such Persons, 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, unless such notice, declaration, request or direction shall have become effective by virtue of Holders of the requisite principal amount of
        Outstanding Securities of such series on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such notice, declaration, request or direction shall automatically and without any
        action by any Person be cancelled and of no further effect.  Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a notice,
        declaration, request or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration, request or direction to which such record date relates, in which event the Trustee may set a new record
        date in respect thereof pursuant to this paragraph.  Nothing in this paragraph shall be construed to render ineffective any notice, declaration, request or direction of the type referred to in this paragraph given at any time to the Trustee and the
        Company by Holders (or their duly appointed agents) of the requisite principal amount of Outstanding Securities of the relevant series on the date such notice, declaration, request or direction is so given.

      

      

      Without limiting the foregoing, a Holder entitled hereunder to give or 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 different part of such principal amount.

      

      

      Section 1.06          Notices, Etc., to Trustee, 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 (which may be via facsimile) to or with the Trustee at [its Corporate Trust Office, Attention: Corporate Trust
          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 instrument or at any other address previously furnished in writing to the Trustee by the Company.

      

      

      The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile
        transmission or other similar unsecured electronic methods; provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of
        such designated persons.  If the Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s
        understanding of such instructions shall be deemed controlling.  The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions or directions
        notwithstanding such instructions or directions conflict or are inconsistent with a subsequent written instruction or direction.  The party providing instructions or directions by unsecured e-mail, facsimile transmission or other similar unsecured
        electronic methods, as aforesaid, agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized
        instructions, and the risk of interception and misuse by third parties.

      Section 1.07          Notice to Holders; Waiver.  Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein
          expressly provided) if in writing and delivered electronically or mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not
          earlier than the earliest date (if any), prescribed for the giving of such notice.  In any case where notice to Holders is given by mail or email, neither the failure to mail or email such notice, nor any defect in any notice so mailed or
          emailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.  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.

        made or duly provided for.  Interest on any overdue principal shall be payable on demand.  Any such interest on any overdue principal that is not so paid on demand shall bear interest at the rate of __% per annum, which shall accrue from the date
        of such demand for payment to the date payment of such interest has been made or duly provided for, and such interest shall also be payable on demand.]

            kind, insert – The Securities of this series are not subject to redemption prior to Stated Maturity.]

      

      

      [If applicable, insert — The Indenture
        contains provisions for defeasance at any time of [(1) the entire indebtedness of this Security or (2)] certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set
        forth in the Indenture.]

      

      

      [If the Security is not an Original Issue Discount
            Security, insert — If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect

      [If the Security is an Original Issue Discount Security,
            insert — If an Event of Default with respect to Securities of this series shall occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect

        Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.  Any such consent or waiver by the Holder of this Security
        shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
        waiver is made upon this Security.

      

      

      As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
        proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
        the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
        as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and
        shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.  The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of
        principal hereof or any premium or interest hereon on or after the respective due dates expressed or provided for herein [Insert, if applicable — or for
        enforcement of the right to convert this Security as provided under the Indenture].

      No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
        Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed [Insert if applicable — or to convert this Security as provided in the Indenture].

        Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied
        by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like
        tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

      

      

      The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple
        of $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a
        different authorized denomination, as requested by the Holder surrendering the same.

      

      

      No service charge shall be made for any such registration of transfer or exchange, but the Company or the Security Registrar may require
        payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

      

      

      Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
        Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
        contrary.

        IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.  EVERY SECURITY AUTHENTICATED AND DELIVERED UPON REGISTRATION OF TRANSFER OF, OR IN EXCHANGE FOR OR IN LIEU OF, THIS SECURITY SHALL BE A GLOBAL SECURITY SUBJECT TO THE FOREGOING, EXCEPT IN

      The Company may, from time to time, by adoption of a Board Resolution and subject to compliance with any other applicable provisions of
        this Indenture, without the consent of the Holders, create and issue pursuant to this Indenture additional Securities of any series of Securities (“Add On Securities”) having terms and conditions identical to those of such series of Outstanding
        Securities, except that such Add On Securities:

      

      

      (A)          may
          have a different issue date, initial interest accrual date or initial Interest Payment Date from such series of Outstanding Securities;

      

      

      (B)          may
          have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on such series of Outstanding Securities; and

      

      

      (C)          may
          have terms specified in such Board Resolution for such Add On Securities that make appropriate adjustments to this Article III applicable to such Add On Securities in order to conform to and ensure compliance with the Securities Act (or
          applicable securities laws) which are not adverse in any material respect to the Holder of any Outstanding Securities (other than such Add On Securities) and which shall not affect the rights or duties of the Trustee.

      

      

      Section 3.02          Denominations.  The Securities of each series shall be issuable only in registered form without coupons in such denominations as shall be specified as
          contemplated by Section 3.01.  In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $2,000 and any integral multiple of $1,000 in
          excess of $2,000.

      

      

      Section 3.03          Execution, Authentication, Delivery and Dating.  The Securities shall be executed on behalf of the Company by any of a Chairman of the Board, if any, the Chief
          Executive Officer, the President, an Executive Vice President, a Senior Vice President, a Vice President, the Chief Financial Officer, the Treasurer, an Assistant Treasurer, the Secretary or an Assistant Secretary.  The signature of any of these
          officers on the Securities may be manual or facsimile.

      

      

      Securities 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.

      

      

      At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
        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, or pursuant to such procedures acceptable to the Trustee set forth
        in, the Company Order shall authenticate and deliver such Securities.  The Stated Maturity, original issue date, interest rate and any other terms of the Securities of such series may, if not previously established by a Board Resolution, Officer’s
        Certificate or indenture supplemental hereto pursuant to Section 3.01, be determined by or pursuant to such Company Order and procedures.  If the form or terms of the Securities of the series have been established in or pursuant to one or more
        Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be provided with, and (subject to
        Section 6.01) shall be fully protected in relying upon, (a) a copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and form of the Securities were established, certified by the Secretary or an Assistant
        Secretary of the Company to have been duly adopted by the Board of Directors and to be in full force and effect as of the date of such certificate, and if the terms and form of such Securities are established by an Officer’s Certificate pursuant to
        general authorization of the Board of Directors, such Officer’s Certificate; (b) an executed supplemental indenture, if any; (c) an Officer’s Certificate delivered in accordance with Section 1.02; and (d) an Opinion of Counsel delivered in
        accordance with Section 1.02 and also stating,

      

      

      (1)          if the
          form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture;

      

      

      
        17

        
          


      

      

      

       

      (2)          if the
          terms of such Securities, or the manner of determining such terms, have been established by or pursuant to Board Resolution as permitted by Section 3.01, that such terms, or the manner of determining such terms, have been established in
          conformity with the provisions of this Indenture;

      

      

      (3)          that
          such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company
          enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles;
          and

      

      

      (4)          that
          all laws and requirements in respect of the execution and delivery by the Company of such Securities have been complied with.

      

      

      If such form or terms have been so established, 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 or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

      

      

      Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a series are not to be originally
        issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.01 or the Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of
        authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

      

      

      Each Security shall be dated the date of its authentication.

      

      

      No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such
        Security a certificate of authentication substantially in the form provided for herein 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.  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 3.09, 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 3.04          Temporary Securities.  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 or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions,
          omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

      

      

      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 the Company shall execute and the Trustee shall
        authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of a like tenor and aggregate principal amount.  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 and tenor.

      Section 3.05          Registration, Registration of Transfer and Exchange.  The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register
          maintained in such office or in any other office or agency of the Company in a Place of Payment being herein sometimes referred to as the “Security Register”; provided, that, in no case shall there be more than one Security Register with respect
          to a series of Securities) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities.  The Trustee is hereby appointed “Security Registrar”
          for the purpose of registering Securities and transfers of Securities as herein provided.

      

      

      Upon surrender for registration of transfer of any Security of any series at the 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 Securities of the same series, of any authorized denominations and of a like tenor
        and aggregate principal amount.

      

      

      At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized
        denominations and of a like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency.  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.

      

      

      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 Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee)
        be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and 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 or Security Registrar 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 3.04, 9.06 or 11.07 not
        involving any transfer.

      

      

      The Company shall not be required (1) to issue, register the transfer of or exchange Securities of any series during a period beginning
        at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (2) to register
        the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

      

      

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

      

      

      (1)          Each
          Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each
          such Global Security shall constitute a single Security for all purposes of this Indenture.

      

      

      (2)          Notwithstanding
          any other provision in this Indenture, and subject to such applicable provisions, if any, as may be specified as contemplated by Section 3.01, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a
          Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary has notified the Company that it is unwilling or unable or no
          longer permitted under applicable law to continue as Depositary for such Global Security and the Company has not appointed a successor within 90 days of receipt of such notice or (B) there shall have occurred and be continuing an Event of Default
          with respect to such Global Security or (C) the Company so directs the Trustee by Company Order, subject to the Depositary’s procedures or (D) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been
          specified for this purpose as contemplated by Section 3.01.

      

      

      
        19

        
          


      

      

      

       

      (3)          Subject
          to Clause (2) above and to such applicable provisions, if any, as may be specified as contemplated by Section 3.01, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for
          a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

      

      

      (4)          Every
          Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or otherwise, shall be
          authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

      

      

      None of the Company, the Trustee nor any agent of the Company or the Trustee 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 Global Security or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

      

      

      Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken by the Depositary.

      

      

      Section 3.06          Mutilated, Destroyed, Lost and Stolen Securities.  If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall
          authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

      

      

      If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any
        Security 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 notice to the Company or the Trustee that such Security has been acquired by a bona fide
        purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not
        contemporaneously outstanding.

      

      

      In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its
        discretion may, instead of issuing a new Security, pay such Security.

      

      

      Upon the issuance of any new Security under this Section, the Company or the Security Registrar 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) in connection therewith.

      

      

      Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an
        original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security 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 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.

      

      

      Section 3.07          Payment of Interest; Interest Rights Preserved.  Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities,
          interest on any Security which 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.

      

      

      
        20

        
          


      

      

      

       

      Any interest on any Security of any series which 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 Holder 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 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 Security of such series and the date of the proposed
          payment, and at the same time the Company shall deposit with the Trustee an amount of money 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 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
          delivered electronically or mailed, first-class postage prepaid, to each Holder of 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 so delivered or mailed, such Defaulted Interest shall be paid to the Persons in whose names the 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).

      

      

      (2)          In lieu
          of the procedure set forth in Clause (1) above, the Company may make payment of any Defaulted Interest on the 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 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, 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.

      

      

      In the case of any Security which is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment
        Date, interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, 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, interest whose Stated Maturity is after the date of conversion of such Security shall not be payable.

      

      

      Section 3.08          Persons Deemed Owners.  Prior to due presentment of a 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 Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.07) any interest on such Security and for all
          other purposes whatsoever, whether or not such 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.

      

      

      
        21

        
          


      

      

      

       

      Section 3.09          Cancellation.  All Securities surrendered for payment, redemption, registration of transfer or exchange or conversion or for credit against any sinking fund
          payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled 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 cancelled by the Trustee.  No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as
          expressly permitted by this Indenture.  All cancelled Securities held by the Trustee shall be disposed of by the Trustee in its customary manner.

      

      

      Section 3.10          Computation of Interest.  Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series
          shall be computed on the basis of a 360-day year of twelve 30-day months.

      

      

      Section 3.11          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 as a convenience to Holders; provided that any such notice 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 a redemption 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.  The Company will promptly notify the Trustee of any changes in the “CUSIP” numbers.

      SATISFACTION AND DISCHARGE

      

      

      Section 4.01          Satisfaction and Discharge of Indenture.  This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of
          conversion, registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

      

      

      (1)          either

      

      

      (A)          all
          Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.06 and (ii) Securities for whose payment money has theretofore
          been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust as provided in Section 10.03) have been delivered to the Trustee for cancellation; or

      

      

      (B)          all
          such Securities not theretofore delivered to the Trustee for cancellation (including, if applicable, upon conversion);

      

      

      (i)          have
          become due and payable, or

      

      

      (ii)          will
          become due and payable at their Stated Maturity within one year, or

      

      

      (iii)          are
          to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee
          as trust funds in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the
          date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

      

      

      
        22

        
          


      

      

      

       

      (2)          the
          Company has paid or caused to be paid all other sums payable hereunder by the Company; and

      

      

      (3)          the
          Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

      

      

      Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.06, the
        obligations, if any, of the Trustee to any Authenticating Agent under Section 6.11 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section, the obligations of the Trustee under Section 4.02
        and the last paragraph of Section 10.03, shall survive such satisfaction and discharge.

      

      

      Section 4.02          Application of Trust Money.  Subject to the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in
          trust and applied by it, in accordance with the provisions of the Securities 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 Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee.  All money deposited with the Trustee pursuant to Section 4.01 (and held by it or any Paying Agent) for
          payment of Securities of a series that is convertible in accordance with the terms of such Securities and that are subsequently converted, shall be returned to the Company.

      REMEDIES

      

      

      Section 5.01          Events of Default.  “Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the
          reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental
          body):

      

      

      (1)          a
          default in any payment of interest on any Security of that series when due and payable and such default continues for 30 days;

      

      

      (2)          a
          default in the payment of principal of (or premium, if any, on) any Security of that series when due and payable at its Maturity;

      

      

      (3)          a
          default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series;

      

      

      (4)          (i) a
          default in the observance or performance of Article VIII or (ii) a default in the observance or performance of any other covenant or agreement contained in this Indenture or applicable to such series pursuant to Section 3.01(16) (other than (a)
          those addressed in (1), (2) or (3) above, or (b) any covenant or warranty a default in whose performance or whose breach has expressly been included in this Indenture solely for the benefit of series of Securities other than that series) which
          default under this clause (ii) continues for a period of 90 days after there has been given to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that
          series, a written notice specifying the default and demanding that such default be remedied and stating that such notice is a “Notice of Default” hereunder;

      

      

      
        23

        
          


      

      

      

       

      (5)          the
          failure to pay at final stated maturity (giving effect to any applicable grace periods and any extensions thereof) the principal amount of any Indebtedness of the Company, or the acceleration of the final stated maturity of any such Indebtedness
          (which Indebtedness is not discharged or which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Company of notice from the Trustee, or by the Company and the Trustee of notice from the Holders of at
          least 25% in principal amount of the Outstanding Securities of that series, of any such failure to pay or acceleration, which notice shall specify the default and demand that such default be remedied and state that such notice is a “Notice of
          Default” hereunder) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated (in each case
          with respect to which the 30-day period described above has elapsed), aggregates $50 million or more at any time;

      

      

      (6)          the
          Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

      

      

      (A)          commences
          a voluntary case;

      

      

      (B)          consents

      (C)          consents
          to the appointment of a Custodian of it or for any substantial part of its property;

      

      

      (D)          makes a
          general assignment for the benefit of its creditors; or takes any comparable action under any foreign laws relating to insolvency; or

      

      

      (E)          takes
          any corporate action to authorize or effect any of the foregoing;

      

      

      (7)          a court
          of competent jurisdiction enters an order or decree under any Bankruptcy Law:

      

      

      (A)          that is
          for relief against the Company or any Significant Subsidiary in an involuntary case;

      

      

      (B)          appoints
          a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or

      

      

      (C)          orders
          the winding up or liquidation of the Company or any Significant Subsidiary;

      

      

      and such order or decree remains unstayed and in effect for 60 days; or

      

      

      (8)          any
          other Event of Default provided with respect to the Securities of that series.

      

      

      The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officer’s
        Certificate of any event which is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Company is taking or proposes to take with respect thereto.

      Section 5.02          Acceleration of Maturity; Rescission and Annulment.  If an Event of Default (other than an Event of Default specified in Section 5.01(6) or 5.01(7) with
          respect to the Company) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that
          series may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) and unpaid interest of
          all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become
          immediately due and payable.  If an Event of Default specified in Section 5.01(6) or 5.01(7) with respect to the Company with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that
          series (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) and unpaid interest thereon shall automatically, and
          without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

      

      

      At any time after such a declaration of acceleration or automatic acceleration with respect to Securities of any series has been made or
        has occurred 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 principal amount of the Outstanding Securities of that series, by
        written notice to the Company and the Trustee, may rescind and annul such declaration or automatic acceleration and its consequences if

      

      

      (1)          the
          Company has paid or deposited with the Trustee a sum sufficient to pay

      

      

      (A)          all
          overdue interest on all Securities of that series,

      

      

      (B)          the
          principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration or automatic acceleration and any interest thereon at the rate or rates prescribed therefor in such
          Securities,

      

      

      (C)          to the
          extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor 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 non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in
          Section 5.13.

      

      

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

      

      

      Section 5.03          Collection of Indebtedness and Suits for Enforcement by Trustee.  The Company covenants that if:

      

      

      (1)          default
          is made in the payment of any interest on any Security when such interest 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, if any, on) any Security at the Maturity thereof,

      

      

      the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such
        Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor
        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.

      

      

      
        25

        
          


      

      

      

       

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

      

      

      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 by such appropriate judicial proceedings as the Trustee shall deem necessary 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 5.04          Trustee May File Proofs of Claim.  In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), or any of the
          property or creditors of the Company (or any other obligor upon the Securities), the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in
          order to have claims of the Holders and the Trustee allowed in any such proceeding.  In particular, the Trustee shall be authorized 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 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other
          amounts due the Trustee under Section 6.06.

      

      

      No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
        Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders,
        vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

      

      

      Section 5.05          Trustee May Enforce Claims Without Possession of Securities.  All rights of action and claims under this Indenture or the Securities may be prosecuted and
          enforced by the Trustee without the possession of any of the Securities 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 in
          respect of which such judgment has been recovered.

      

      

      Section 5.06          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 any premium or interest, upon presentation of the Securities 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 under Section 6.06;

      

      

      SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities 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 amounts due and payable on such Securities for principal and any premium and interest, respectively; and

      

      

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

      

      

      
        26

        
          


      

      

      

       

      Section 5.07          Limitation on Suits.  No Holder of any Security of any series 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 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 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 of such Holders.

      

      

      Section 5.08          Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert.  Notwithstanding any other provision in this Indenture, the Holder of
          any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.07) interest on such Security on the respective Stated Maturities expressed in such Security
          (or, in the case of redemption, on the Redemption Date) and, if applicable, to convert such Security in accordance with the terms of such Securities and to institute suit for the enforcement of any such payment and right to convert, and such
          rights shall not be impaired without the consent of such Holder.

      

      

      Section 5.09          Restoration of Rights and Remedies.  If the Trustee or any Holder 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, subject to any determination in such proceeding, the Company, the Trustee and the
          Holders shall 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 5.10          Rights and Remedies Cumulative.  Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in
          the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders 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.

      

      

      
        27

        
          


      

      

      

       

      Section 5.11          Delay or Omission Not Waiver.  No delay or omission of the Trustee or of any Holder of any Securities 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 an 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, as the case may be.

      

      

      Section 5.12          Control by Holders.  The Holders of a majority in 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)          subject
          to the provisions of Section 6.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or Officers of the Trustee, determine, and the Trustee shall have received a
          legal opinion stating, that the proceedings so directed would involve the Trustee in personal liability.

      

      

      Section 5.13          Waiver of Past Defaults.  The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders
          of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default

      

      

      (1)          in the
          payment of the principal of or any premium or interest on any Security of such series, or

      

      

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

      

      

      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 impair any right consequent thereon.

      

      

      Section 5.14          Undertaking for Costs.  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,
          suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs, including reasonable attorney’s fees and expenses, against any such party
          litigant, having due regard to the merits and good faith of the claims or defenses made by the party litigant; provided that this Section shall not apply
          to any suit instituted by the Trustee, to any suit instituted by any Holders of the Securities, or group of Holders of the Securities, holding in the aggregate more than 10% of the principal amount of the Outstanding Securities of any series, or
          to any suit instituted by any Holder of the Outstanding Securities for the enforcement of the payment of principal of or any premium or interest on any Outstanding Securities held by such Holder, on or after the respective due dates expressed or
          provided for in such Outstanding Securities, and provided, further,
          that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or the Trustee or, if applicable, in any suit for the
          enforcement of the right to convert any Security in accordance with the terms of such Security.

      

      

      Section 5.15          Waiver of Usury, Stay 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.

      

      

      
        28

        
          


      

      

      

       

      ARTICLE VI

      

      

      THE TRUSTEE

      

      

      The Trustee hereby accepts the trust imposed upon it by this Indenture and covenants and agrees to perform the same, as herein expressed.

      

      

      Section 6.01          Duties of Trustee.

      

      

      (a)          If an Event of Default has
          occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this 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.

      

      

      (b)          Except during the
          continuance of an Event of Default:

      

      

      (1)          The
          Trustee need perform only those duties as are specifically set forth in this Indenture and no others, and no covenants or obligations shall be implied in or read into this Indenture against the Trustee.

      

      

      (2)          In the
          absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the
          requirements of this Indenture, but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the certificates and
          opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

      

      

      (c)          Notwithstanding anything
          to the contrary contained herein, the Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

      

      

      (1)          This
          paragraph does not limit the effect of paragraph (b) of this Section 6.01.

      

      

      (2)          The
          Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts.

      

      

      (3)          The
          Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received from the Holders of a majority in principal amount of the Outstanding Securities of any series pursuant to
          Section 5.12 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such
          series.

      

      

      (4)          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 to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

      

      

      (d)          Every provision of this
          Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 6.01 and to the provisions of the Trust Indenture Act.

      

      

      (e)          The Trustee shall not be
          liable for interest on any assets received by it, except as the Trustee may agree in writing with the Company.  Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by law.

      

      

      
        29

        
          


      

      

      

       

      Section 6.02          Rights of Trustee.  Subject to Section 6.01:

      

      

      (a)          The Trustee may rely
          conclusively and shall be protected in acting or refraining from acting on any document (whether in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper person.  The Trustee need not
          investigate any fact or matter stated in any document.

      

      

      (b)          Before the Trustee acts or
          refrains from acting, it may conclusively rely on an Officer’s Certificate or an Opinion of Counsel covering such matters as it shall reasonably request.  The Trustee shall not be liable for any action it takes or omits to take in good faith in
          reliance on such certificate or opinion.

      

      

      (c)          The Trustee may execute
          any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys or independent contractors and the Trustee will not be responsible for any misconduct or negligence on the part of any agent,
          attorney or independent contractor appointed with due care by it hereunder.

      

      

      (d)          The Trustee shall not be
          liable for any action taken, suffered, or omitted to be taken 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.

      

      

      (e)          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, consent, order, approval, bond, debenture, note 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 at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

      

      

      (f)          The Trustee shall be under
          no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders, pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee
          security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby.

      

      

      (g)          The Trustee may consult
          with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by the Trustee hereunder in good
          faith and in reliance thereon.

      

      

      (h)          The Trustee shall not be
          deemed to have notice of any default hereunder or Event of Default unless written notice of any event which is in fact such a default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice
          references the Securities and this Indenture.

      

      

      (i)          The rights, privileges,
          protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
          other Person employed to act hereunder.

      

      

      (j)          In no event shall the
          Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such
          loss or damage and regardless of the form of action.

      

      

      (k)          The Trustee may request
          that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any
          person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

      

      

      (l)          Any request or direction

      Section 6.03          Individual Rights of Trustee.  The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with
          the Company or its Affiliates with the same rights it would have if it were not Trustee.  Any Authenticating Agent, Paying Agent or Security Registrar may do the same with like rights.  However, the Trustee must comply with Sections 6.09 and
          6.10.

      

      

      Section 6.04          Trustee’s Disclaimer.  The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities,
          it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or
          in the Securities other than the Trustee’s certificate of authentication, or the use or application of any funds received by a Paying Agent other than the Trustee.  Any Authenticating Agent shall be entitled to the benefit of the preceding
          sentence.  The Trustee shall not be charged with knowledge of the identity of any Significant Subsidiary unless a Responsible Officer of the Trustee shall have received notice thereof in accordance with Section 1.06 hereof from the Company or any
          Holder.

      

      

      Section 6.05          Notice of Default.  If a default with respect to Securities of any series occurs and is continuing and if it is known to the Trustee, the Trustee shall deliver
          to each Holder of Securities of such series notice of the uncured default within 90 days after such default occurs; provided, however, that in the case of any default of the character specified in Section 5.01(4) with respect to Securities of
          such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof.  Except in the case of a default in payment of principal (or premium, if any) of, or interest on, any Security (including payments pursuant
          to the mandatory redemption provisions of such Security, if any), the Trustee may withhold the notice if and so long as a committee of Responsible Officers in good faith determines that withholding the notice is in the interest of the Holders of
          Securities of such series.  For purposes 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 6.06          Compensation and Indemnity.  The Company shall pay to the Trustee from time to time such compensation for its services as the Company and the Trustee shall
          from time to time agree in writing.  The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.  The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses made
          by it, including costs of collection, in addition to compensation for its services.  Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents, accountants, experts and counsel.

      

      

      The Company shall indemnify the Trustee against any and all loss, liability, claim, damage, taxes or expense (including reasonable
        attorneys’ fees and expenses) incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expense of enforcing this Indenture against the Company (including
        this Section 6.06) and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its rights, powers or duties hereunder.  The Trustee
        shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company of its indemnity obligations hereunder.  The Company may, subject to the approval of the Trustee,
        defend the claim, and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense.  The Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel; provided, however, that the Company shall not be required to pay such fees and expenses if it
        assumes the Trustee’s defense and, in the Trustee’s reasonable judgment, there is no conflict of interest between the Company and such parties in connection with such defense.  The Company need not pay for any written settlement made without its
        prior written consent, which consent will not be unreasonably delayed, conditioned or withheld.  The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own
        willful misconduct or negligence.

      

      

      To secure the Company’s payment obligations in this Section 6.06, the Trustee shall have a lien prior to the Securities on all money or
        property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

      

      

      The Company’s payment obligations pursuant to this Section 6.06 shall survive the satisfaction or discharge of this Indenture, any
        rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee.  Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses after the
        occurrence of an Event of Default specified in Section 5.01(6) or (7), the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

      

      

      
        31

        
          


      

      

      

       

      The provisions of this Section shall survive the termination of this Indenture.

      

      

      Section 6.07          Replacement of Trustee.  The Trustee may resign at any time with respect to the Securities of one or more series by so notifying the Company in writing 30 days
          prior to the effectiveness of such resignation.  The Holder or Holders of a majority in principal amount of the Outstanding Securities of a series may remove the Trustee with respect to Securities of such series by so notifying the Company and
          the Trustee in writing 30 days prior to the effectiveness of such removal.  The Company may remove the Trustee if:

      

      

      (1)          the
          Trustee fails to comply with Section 6.09;

      

      

      (2)          the
          Trustee is adjudged bankrupt or insolvent;

      

      

      (3)          a
          receiver, custodian, or other public officer takes charge of the Trustee or its property; or

      

      

      (4)          the
          Trustee becomes incapable of acting.

      

      

      With respect to the Securities of one or more series, if the Trustee resigns or is removed by the Company or by the Holders of a majority
        in principal amount of the Outstanding Securities of that series, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a
        successor Trustee with respect to Securities of that or those series.  If, within one year after such resignation or removal 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 in
        accordance with this Section 6.07, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.

      

      

      A successor Trustee with respect to one or more series of Securities shall deliver a written acceptance of its appointment to the
        retiring Trustee and to the Company.  Thereupon the resignation or removal of the retiring Trustee with respect to such series of Securities shall become effective, and the successor Trustee shall have all the rights, powers and duties of the
        Trustee under this Indenture with respect to such series of Securities.  The successor Trustee shall mail a notice of its succession to each Holder of Securities of that or those series.  The retiring Trustee shall (upon payment of its charges
        hereunder) promptly transfer all property held by it as Trustee with respect to such series of Securities to the successor Trustee, subject to the lien provided for in Section 6.06.

      

      

      If a successor Trustee with respect to a series of Securities does not take office within 60 days after the retiring Trustee resigns or
        is removed, the retiring Trustee (at the Company’s expense), the Company or the Holder or Holders of at least 10% in principal amount of the Outstanding Securities of that series may petition at the expense of the Company any court of competent
        jurisdiction for the appointment of a successor Trustee with respect to such series.

      

      

      If the Trustee fails to comply with Section 6.09, unless the Trustee’s duty to resign is stayed as provided in Trust Indenture Act
        Section 310(b), any Holder who has been a bona fide holder of Securities of a series for at least six months may petition any court of competent jurisdiction for the removal of the Trustee with respect to such series and the appointment of a
        successor Trustee with respect to such series.

      

      

      Notwithstanding replacement of the Trustee pursuant to this Section 6.07, the Company’s obligations under Section 6.06 shall continue for
        the benefit of the retiring Trustee.

      

      

      Section 6.08          Successor Trustee by Merger, Etc.  If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust
          business to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise qualified and eligible hereunder, be
          the successor Trustee.

      

      

      
        32

        
          


      

      

      

       

      In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts
        created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated;
        and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in
        all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

      

      

      Section 6.09          Eligibility; Disqualification.  The Trustee shall at all times satisfy the requirements of Trust Indenture Act Section 310(a)(1) and Trust Indenture Act
          Section 310(a)(5).  The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.  The Trustee shall comply with Trust Indenture Act Section 310(b), subject to
          its right to apply for a stay of its duty to resign under the penultimate paragraph of Trust Indenture Act Section 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act Section 310(b)(1) any indenture or indentures under which other securities or
          certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act Section 310(b)(1) are met.

      

      

      Section 6.10          Preferential Collection of Claims against Company.  The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor relationship
          listed in Trust Indenture Act Section 311(b).  A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated.

      

      

      Section 6.11          Appointment of Authenticating Agent.  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 original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.06, 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.  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 acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof 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 authority.  If such Authenticating
          Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said 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.  If 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.

      

      

      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 any further act on the part of the Trustee or the Authenticating Agent.

      

      

      An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company.  The Trustee may at
        any time terminate the agency of an Authenticating Agent by giving written notice thereof 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 may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the
        manner provided in Section 1.07 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve.  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.  No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

      

      

      
        33

        
          


      

      

      

       

      Except with respect to an Authenticating Agent appointed at the request of the Company, the Trustee agrees to pay to each Authenticating
        Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.06.

      

      

      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 the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

      

      

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

      Section 7.02          Preservation of Information; Communications to Holders.  The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses
          of Holders contained in the most recent list furnished to the Trustee as provided in Section 7.01 and the names and addresses of Holders received by the Trustee in its capacity as Security Registrar.  The Trustee may destroy any list furnished to
          it as provided in Section 7.01 upon receipt of a new list so furnished.

      

      

      The rights of the Holders to communicate with other Holders with respect to their rights under this Indenture or under the Securities,
        and the corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act.

      

      

      Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the
        Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant to the Trust Indenture Act.

      Section 7.03          Reports by Trustee.  The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant
          to the Trust Indenture Act at the times and in the manner provided pursuant thereto.  Reports so required to be transmitted at stated intervals of not more than 12 months shall be transmitted no later than November 15 in each calendar year,
          commencing in the year in which this Indenture is executed.

          that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is filed with the Commission.  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 Officer’s Certificates).

          its assets, the predecessor Company shall not be released from the obligation to pay the principal of (and premium, if any) and interest on the Securities.  When a surviving or successor Person duly assumes all of the obligations of the Company
          pursuant hereto and pursuant to the Securities, except in the circumstances described in the proviso to the preceding sentence, the predecessor shall be relieved of the performance and observance of all obligations and covenants of this Indenture

          at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:

      (2)          to add

      (6)          to

      Section 9.02          Supplemental Indentures with Consent of Holders.  With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities
          of each series affected by such supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by 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 Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall,
          without the consent of the Holder of each Outstanding Security of each series so affected:

      

      

      (1)          change
          the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the

      (4)          adversely
          affect any right of repayment or repurchase at the option of the Holder; or

      

      

      (5)          reduce
          or postpone any sinking fund or similar provision.

      

      

      A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely 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.

      

      

      
        37

        
          


      

      

      

       

      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.

      

      

      Section 9.03          Execution of Supplemental Indentures.  In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the
          modifications thereby of the trusts created by this Indenture, the Trustee shall be given, and (subject to Section 6.01) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of
          such supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent in the Indenture to the execution of the supplemental indenture have been complied with, and that the supplemental indenture is a legal, valid
          and binding obligation of the Company, enforceable against it in accordance with its terms.  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
          under this Indenture or otherwise.

      

      

      Section 9.04          Effect of Supplemental Indentures.  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 shall be bound thereby.

      

      

      Section 9.05          Conformity with Trust Indenture Act.  Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture
          Act.

      

      

      Section 9.06          Reference in Securities to Supplemental 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 such new Securities may be authenticated and delivered by the Trustee in exchange for
          Outstanding Securities of such series.

      

      

      ARTICLE X

      

      

      COVENANTS

      

      

      Section 10.01          Payment of Securities.  The Company covenants and agrees for the benefit of each series of Securities that it will pay the principal of and interest on the
          Securities of that series on the dates and in the manner provided in the Securities of that series and this Indenture.  An installment of principal, premium, if any, or interest on the Securities shall be considered paid on the date it is due if
          the Trustee or Paying Agent (other than the Company or an Affiliate of the Company) holds for the benefit of the Holders, on that date, immediately available funds deposited and designated for and sufficient to pay the installment.

      

      

      The Company shall pay interest on overdue principal and on overdue installments of interest at the rate specified in the Securities
        compounded semi-annually, to the extent lawful.

      

      

      Section 10.02          Maintenance of Office or Agency.  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, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of any series that is convertible may be surrendered for conversion, and where
          notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served.  The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office
          or agency.  If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
          Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

      

      

      
        38

        
          


      

      

      

       

      The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be
        presented or surrendered for any or all 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 each Place of Payment for Securities of any
        series for such purposes.  The Company shall 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.  The Company hereby initially designates the
        Corporate Trust Office as such agency of the Company for the foregoing purposes.

      

      

      Section 10.03          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 Securities, it
          will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any
          premium and interest 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, it will, on or prior to each due date of the
        principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, 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 for any series of Securities other than the Trustee to execute and deliver to the Trustee an
        instrument in which such Paying Agent shall agree with the Trustee and the Company, subject to the provisions of this Section, that such Paying Agent will:

      

      

      (1)          Hold
          all sums held by it for the payment of the principal of, premium, if any, or interest on Securities of such series for the benefit of the Persons entitled thereto until such sum 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 of that series) in the making of any payment of principal, premium, if any, or interest; and

      

      

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

      

      

      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 money.

      

      

      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 or
        any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on 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 thereof, 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 a newspaper published in the English language, customarily
        published on each Business Day and of general circulation in New York City, 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 10.04          Corporate Existence.  Subject to Article VIII, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its
          corporate existence in accordance with its organizational documents and its rights (charter and statutory) and corporate franchises; provided, however, that the Company shall not be required to preserve any right or franchise, if the Company shall determine that the preservation thereof is no longer
          desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole.

      

      

      Section 10.05          Compliance Certificate; Notice of Default.

      

      

      (a)          The Company shall deliver
          to the Trustee within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officer’s Certificate complying with Section 314(a)(4) of the Trust Indenture Act and stating, as to each such officer signing such
          certificate, whether or not the signer knows of any failure by the Company or any Subsidiary of the Company to comply with any conditions or covenants in this Indenture and, if such signer does know of such a failure to comply, the certificate
          shall describe such failure with particularity.  The Officer’s Certificate shall also notify the Trustee should the relevant fiscal year end on any date other than the current fiscal year end date.

      

      

      (b)          The Company shall, so long
          as any of the Securities of any series are outstanding, deliver to the Trustee, within 30 days after becoming aware of any Event of Default with respect to such series under this Indenture, an Officer’s Certificate specifying such Event of
          Default, its status and what action the Company is taking or proposes to take with respect thereto.

      

      

      Section 10.06          Waiver of Certain Covenants.  Except as otherwise specified as contemplated by Section 3.01 for Securities of such series, the Company may, with respect to the
          Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.01(16), 9.01(2) or 9.01(7) for the benefit of the Holders of such series if before
          the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such
          term, provision or condition, but no such waiver shall extend to or affect such term, provision 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 term, provision or condition shall remain in full force and effect.

      

      

      ARTICLE XI

      

      

      REDEMPTION OF SECURITIES

      

      

      Section 11.01          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 3.01 for Securities of any series) in accordance with this Article.

      

      

      Section 11.02          Election to Redeem; Notice to Trustee.  The election of the Company to redeem any Securities shall be evidenced by a Board Resolution.  In case of any
          redemption at the election of the Company of the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of
          such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed.  In the case of any redemption of Securities (a) prior to the expiration of any
          restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this
          Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction or condition.

      

      

      Section 11.03          Selection by Trustee of Securities to Be Redeemed.  If less than all the Securities of any series are to be redeemed (unless all of the Securities of such
          series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date from the Outstanding
          Securities of such series not previously called for redemption, by lot or, if the Securities to be redeemed are Global Securities, pursuant to the applicable procedures of the Depositary, 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 thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for
          Securities of that series.

      

      

      
        40

        
          


      

      

      

       

      If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the
        portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption.  Securities which have been converted during a selection of Securities to be redeemed shall be
        treated by the Trustee as Outstanding for the purpose of such selection.

      

      

      The Trustee shall notify the Company 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.

      

      

      The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether
        such Security is to be redeemed in whole or in part.  In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum
        authorized denomination) for such Security.

      

      

      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 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

      

      

      Section 11.04          Notice of Redemption.  Notice of redemption shall be delivered electronically or by first-class mail, postage prepaid, mailed not less than 30 nor more than 60
          days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register.

      

      

      All notices of redemption shall state:

      

      

      (1)          the
          Redemption Date,

      

      

      (2)          the
          Redemption Price, or if not then ascertainable, the manner of calculation thereof,

      

      

      (3)          if less
          than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed), the identification (and, in the case of partial
          redemption of any Securities, the principal amount) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series constituting a single Security are to be redeemed, the principal amount of the
          particular Security to be redeemed,

      

      

      (4)          that on
          the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

      

      

      (5)          in the
          case of any Securities that are convertible pursuant to the terms of such Securities, the conversion price or rate, the date on which the right to convert the principal of the Securities to be redeemed will terminate and the place or places where
          such Securities may be surrendered for conversion,

      

      

      (6)          the
          place or places where such Securities are to be surrendered for payment of the Redemption Price,

      

      

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

      

      

      (8)          applicable
          CUSIP Numbers and the statement in Section 3.11.

      

      

      Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
        request and with the notice information provided to the Trustee, by the Trustee in the name and at the expense of the Company and shall be irrevocable; provided,
        in the latter case, the Company will give the Trustee at least ten days’ prior notice of the date of the giving of the notice (unless a shorter notice shall be satisfactory to the Trustee).  Notice of redemption of Securities to be redeemed at the
        election of the Company received by the Trustee shall be given by the Trustee to each Paying Agent in the name of and at the expense of the Company.

      

      

      
        41

        
          


      

      

      

       

      Section 11.05          Deposit of Redemption Price.  At or prior to 11:00 a.m. New York City time on the 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, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment
          Date (unless otherwise specified as contemplated by Section 3.01)) accrued interest on, all the Securities which are to be redeemed on that date other than any Securities called for redemption on that date which have been converted prior to the
          date of such deposit.

      

      

      If any Security called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and
        held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 3.07) be paid to the Company upon Company
        Request or, if then held by the Company, shall be discharged from such trust.

      

      

      Section 11.06          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, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest.  Upon
          surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.01, installments of
          interest 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 3.07.

      

      

      If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall,
        until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

      

      

      Section 11.07          Securities Redeemed in Part.  Any Security which is to be redeemed only in part 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 and of like tenor, 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.

      SINKING FUNDS

      

      

      Section 12.01          Applicability of Article.  The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as
          otherwise specified as contemplated by Section 3.01 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 Securities of any series is herein referred to as an “optional sinking fund payment”.  If provided for by the terms of Securities of any
        series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.02.  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 12.02          Satisfaction of Sinking Fund Payments with Securities.  The Company (1) may deliver Outstanding Securities of a series (other than any Securities previously
          called for redemption) and (2) may apply as a credit Securities of a series which have been converted pursuant to the terms of such Securities or 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, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series
          required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been
          previously so credited.  Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund
          payment shall be reduced accordingly.

      Section 12.03          Redemption of Securities for Sinking Fund.  Not less than 45 days prior to each sinking fund payment date for any series of Securities, the Company will
          deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing 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 and the
          portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 12.02 and the basis for such credit, and will also deliver to the Trustee any Securities to be so delivered.  Not 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 11.03 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 11.04.  Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07.

      

      

      ARTICLE XIII

      

      

      DEFEASANCE AND COVENANT DEFEASANCE

      

      

      Section 13.01          Company’s Option to Effect Defeasance or Covenant Defeasance.  The Company may elect, at its option by Board Resolution at any time, to have either Section
          13.02 or Section 13.03 applied to the Outstanding Securities of any series designated pursuant to Section 3.01 as being defeasible pursuant to this Article XIII (hereinafter called a “Defeasible Series”), upon compliance with the conditions set
          forth below in this Article XIII.

      

      

      Section 13.02          Defeasance and Discharge.  Upon the Company’s exercise of the option provided in Section 13.01 to have this Section 13.02 applied to the Outstanding Securities
          of any Defeasible Series, the Company shall be deemed to have been discharged from its obligations, with respect to the Outstanding Securities of such series, as provided in this Section on and after the date the conditions set forth in Section
          13.04 are satisfied (hereinafter called “Defeasance”).  For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities of such series and to
          have satisfied all its other obligations under the Securities of such series and this Indenture with respect to such Securities (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same provided to
          it by the Company), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of Securities of such series to receive, solely from the trust fund described in Section 13.04 and as
          more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities of such series when payments are due, (2) the Company’s obligations with respect to the Securities of such series under
          Sections 3.04, 3.05, 3.06, 10.02 and 10.03, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article XIII.  Subject to compliance with this Article XIII, the Company may exercise its option provided in
          Section 13.01 to have this Section 13.02 applied to the Outstanding Securities of any Defeasible Series notwithstanding the prior exercise of its option provided in Section 13.01 to have Section 13.03 applied to the Outstanding Securities of such
          series.

      

      

      Section 13.03          Covenant Defeasance.  Upon the Company’s exercise of the option provided in Section 13.01 to have this Section 13.03 applied to the Outstanding Securities of
          any Defeasible Series, (1) the Company shall be released from its obligations under Section 8.01, Section 10.04, and such other covenants as may have been made applicable to such Defeasible Series pursuant to Sections 3.01(16), 9.01(2) and
          9.01(7) and (2) the occurrence of any event specified in Sections 5.01(3), 5.01(4) (with respect to any of Sections 8.01 or 10.04 or such other applicable covenants referred to in the preceding clause (1)) and 5.01(5) shall be deemed not to be or
          result in an Event of Default (hereinafter called “Covenant Defeasance”).  For this purpose, such Covenant Defeasance means that 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 specified Section (to the extent so specified in the case of Section 5.01(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to
          any other provision herein or in any other document, but the remainder of this Indenture and the Securities of such series shall be unaffected thereby; provided
          that notwithstanding a Covenant Defeasance with respect to Section 8.01, any Person to whom a transfer, sale, lease or other disposition is made pursuant to Section 8.01, shall as a condition to such transfer, sale, lease or other disposition,
          assume by an indenture supplemental hereto in form satisfactory to the Trustee, executed by such successor Person and delivered to the Trustee, the obligations of the Company to the Trustee under Section 6.06 and the second to the last paragraph
          of Section 13.05.

      

      

      
        43

        
          


      

      

      

       

      Section 13.04          Conditions to Defeasance or Covenant Defeasance.  The following shall be the conditions to application of either Section 13.02 or Section 13.03 to the
          Outstanding Securities of any Defeasible Series:

      

      

      (1)          The
          Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee that satisfies the requirements contemplated by Section 6.09 and agrees to comply with the provisions of this Article XIII 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 Outstanding Securities of such series, (A) money in an amount, or (B) U.S.
          Government Obligations that through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a
          combination thereof, in each case sufficient, 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 any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on the Securities of such series on the respective Stated Maturities or on redemption, in accordance with the terms of this
          Indenture and the Securities of such series.  As used herein, “U.S. Government Obligation” means (x) any security that is (i) a direct obligation of the United States of America for the payment of which full faith and credit of the United States
          of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit
          obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities
          Act) as custodian with respect to any U.S. Government Obligation specified in Clause (x) and held by such custodian for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on
          any such U.S. Government Obligation, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount
          payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt.

      

      

      (2)          In the
          case of an election under Section 13.02, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the
          date first set forth hereinabove, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of the Outstanding Securities of such
          series will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to the Securities of such series and will be subject to Federal income tax on the same amount,
          in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur.

      

      

      (3)          In the
          case of an election under Section 13.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Securities of such series will not recognize gain or loss for Federal income tax
          purposes as a result of the deposit and Covenant Defeasance to be effected with respect to the Securities of such series and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case
          if such deposit and Covenant Defeasance were not to occur.

      

      

      (4)          After
          giving pro forma effect to such Defeasance or Covenant Defeasance, no Event of Default or event that (after notice or lapse of time or both) would become an Event of Default with respect to the Securities of such series shall have occurred and be
          continuing at the time of such deposit or, with regard to any such event specified in Sections 5.01(6) and (7), at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed
          satisfied until after such 90th day).

      

      

      
        44

        
          


      

      

      

       

      (5)          Such
          Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act, assuming all Securities Outstanding hereunder were in default within the meaning of the Trust Indenture
          Act.

      

      

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

      

      

      (7)          The
          Company shall have delivered to the Trustee an Opinion of Counsel to the effect that any trust resulting from the deposit under this Section does not require registration under the U.S. Investment Company Act of 1940, as amended.

      

      

      (8)          If the
          Securities of such series are to be redeemed, either notice of such redemption shall have been given or the Company shall have given the Trustee irrevocable directions to give notice of such redemption in the name, and at the expense of, the
          Company, under arrangements satisfactory to the Trustee.

      

      

      (9)          The
          Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.

      

      

      Section 13.05          Deposited Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions.  Subject to the provisions of the last paragraph of
          Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.06, the Trustee and any such other trustee are
          referred to collectively as the “Trustee”) pursuant to Section 13.04 in respect of the Securities of any Defeasible Series shall be held in trust and applied by the Trustee, in accordance with the provisions of the Securities of such series and
          this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of Securities of such series, of all sums due and to become due
          thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law.

      

      

      The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government
        Obligations deposited pursuant to Section 13.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge that by law is for the account of the Holders of Outstanding Securities.

      

      

      Anything in this Article XIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon
        Company Request any money or U.S. Government Obligations held by it as provided in Section 13.04 with respect to Securities of any Defeasible Series that, 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 that would then be required to be deposited to effect an equivalent Defeasance or Covenant Defeasance with respect to the Securities of such series.

      

      

      Section 13.06          Reinstatement.  If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article XIII with respect to the Securities of any
          series by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture with respect to the Securities of such series
          and under such Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article XIII with respect to Securities of such series until such time as the Trustee or Paying Agent is permitted to apply all money
          held in trust pursuant to Section 13.05 with respect to Securities of such series in accordance with this Article XIII; provided, however, that if the Company makes any payment of principal of or any premium or interest on any Security of such series following the reinstatement of its obligations, the
          Company, as the case may be, shall be subrogated to the rights of the Holders of Securities of such series to receive such payment from the money so held in trust.

      

      

      
        45

        
          


      

      

      

       

      Section 13.07          Qualifying Trustee.  Any trustee appointed pursuant to Section 13.04 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.

      

      

      This instrument 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 instrument. The exchange of copies of this instrument and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this instrument as to the
        parties hereto and may be used in lieu of the original instrument for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signature for all purposes.
